What is a cabin pump ?


Manual cabin pump for cab tilting, including cabin pump body, plunger assembly

, reversing handle, reversing valve assembly, lifting nozzle and lowering nozzle,

There are mounting threaded holes on the side of the cabin pump body, cabin lifting oil nipple and lowering oil

The nozzle is located on the side of the cabin pump body, which is at the same location as the mounting threaded hole of the tilt pump body.

On one side; the drop nozzle is located at the end of the reversing valve assembly, and is connected to the

The rotation axis of the reversing valve assembly is coaxial. The utility model avoids due to poor road conditions, the oil nozzle was damaged by obstacles, resulting in damage to the hydraulic system when the cab is tilting over; the cabin pump body is easier to process, and the reversing valve has only one radial oil outlet and one axial oil outlet,the oil circuit between the reversing valve and the cabin pump body only needs to control the radial oil outlet

It is enough to seal at the place, which makes the structure of the whole manual hydraulic tilting pump simpler and more efficient,can be more reliable.

Cabin pump for heavy duty trucks

1. Refactored software architecture to support 32/64-bit and larger image processing;

2. Support more special effects filter functions;

3. Added portrait beauty functions, facial remodeling, etc.;

4. Support more basic adjustment functions and more brush functions;

5. Contains more material text functions;

6. New functions such as intelligent puzzle and automatic cutout are added.

The purpose of this is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of lifting oil nozzle and lower

The oil drop nozzle is not easy to be damaged, the structure is simple, the processing technology is simplified, and the manual cabin hydraulic pump for cab tilt turnover with superior performance.

The technical scheme adopted by the technical problem that the utility model solves is:

A kind of manual hydraulic cab tilt pump for cab overtilting is provided, comprising cabin pump body, plunger assembly, reversing handle, reversing valve assembly,

The lifting nozzle and the lowering nozzle are provided with mounting threaded holes on the side of the tiltig pump body, which are characterized in that the lifting nozzle and the lowering nozzle are arranged on the pump

The side of the cabin pump body is located on the same surface as the mounting threaded hole of the cabin pump body.

[0006]

In specific implementation, the descending oil nozzle is arranged at the end of the reversing valve assembly, which is coaxial with the rotation axis of the reversing valve assembly.

There is an axial oil outlet in the axial direction of the rotating shaft of the valve assembly, and the end of the output channel of the axial oil outlet is provided with a blockage, which lifts the oil nozzle.

It communicates with the output channel of the axial oil outlet.

[0007]

The mounting threaded holes are used to connect with the frame, and the mounting threaded holes on the lifting nozzle and the lowering nozzle are in the pump body.

On the same side and perpendicular to the surging direction of the plunger, the lifting nozzle is parallel to the rotation axis of the reversing valve assembly, and the center of the falling nozzle is

The line is coaxial with the axis of the rotating shaft of the reversing valve assembly, and there is a radial oil outlet between the centerline of the drop nozzle and the reversing valve assembly.

The reversing valve assembly of the utility model is provided with a radial oil outlet and an axial oil outlet.

The beneficial effect of the present utility model is:

[0009]

1. Since the lifting nozzle and the lowering nozzle are located on the side of the pump body near the installation threaded hole, the

The oil nozzle was damaged by the obstacle, which caused damage to the hydraulic tilting system of the cab turning

2, when adopting the installation structure of the present utility model, the processing of the cab tilt pump body is simpler, and the reversing valve has only one radial oil outlet

And an axial oil outlet, the oil circuit between the reversing valve and the cab tilt pump body only needs to control the seal at the radial oil outlet, so that the whole

A manual hydraulic cab tilting pump has a simpler structure and more reliable performance.

Description of drawings

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

1. Pump body 2. Lowering nozzle 3. Lifting nozzle 4. Blocking 5. Reversing valve assembly 6. Reversing handle

7. Plunger assembly 8. Rocker arm A, radial oil outlet B, axial oil outlet C, mounting threaded holes.

detailed description

[0015]

In Figure 2, a manual hydraulic pump for cab flipping includes a pump body 1, a plunger assembly 7, a reversing handle 6, Direction valve assembly 5, lift oil nozzle 3, lower oil nozzle 2 and rocker arm 8; there are two installations on the side of cab tilting pump body 1 for connecting with the frame

Threaded hole C, lift nipple 3 and drop nipple 2 are on the same side as the two mounting threaded holes C on pump body 1 and are on the same side as the plunger

The movement direction of the assembly 7 is vertical and parallel to the rotation axis of the reversing valve assembly 5, wherein the center line of the descending oil nozzle 2 and the reversing valve assembly

5 The axis of rotation is coaxial; the reversing valve assembly 5 has only one radial oil outlet A and one axial oil outlet B, and the axial oil outlet B

There is a plug 4 on the lower surface of the output channel leading to the cab pump body 1, and the oil lift nozzle 3 is communicated with the output channel of the axial oil outlet B.

The utility model is because the lifting oil nozzle 3 and the descending oil nozzle 2 are located on the side of the cabin pump body by the installation threaded hole A, which avoids the

Due to the poor road conditions, the lift nozzle 3 and the drop nozzle 2 were damaged by obstacles, which caused damage to the hydraulic tilting system of the cab overturning.

Bad. After adopting this installation structure at the same time, the reversing valve assembly 5 has only one radial oil outlet A and one axial oil outlet B,

The oil circuit between the reversing valve assembly 5 and the cabin pump body 1 only needs to control the seal at the radial oil outlet A. In short, the utility model

The involved manual hydraulic cab tilt pump for cab turning has the advantages of simpler structure and more reliable performance.

The basic working principle of the embodiment of the present invention is the same as the prior art, and is not described here.

Above-described embodiment is the description of the present utility model, is not the limitation of the present utility model, any in the present utility model

The structure after simple transformation on the basis of the model belongs to the protection scope of the present invention.
