Abstract
A manual hydraulic pump used for overturn of a driving cab comprises a pump body, a plunger assembly, a reversing handle, a reversing valve assembly, a lifting lubricating nipple and a descending lubricating nipple. An installation threaded hole is arranged on a side face of the pump body. The lifting lubricating nipple and the descending lubricating nipple are arranged on a side face of the pump body, and are on the same face with the installation threaded hole of the pump body. The descending lubricating nipple is arranged on the tail end of the reversing valve assembly, and is coaxial with a rotary axis of the reversing valve assembly. According to the manual hydraulic pump used for the overturn of the driving cab, the occasion that a hydraulic system for the overturn of the driving cab is damaged due to the fact that the lubricating nipples are broken by stumbling blocks due to a poor road condition is avoided; the pump body is easy to machine; a reversing valve is only provided with one radial oil outlet and one axial oil outlet, so an oil line between the reversing valve and the pump body can be controlled by means of seal control of the radial oil outlet; and the whole manual hydraulic pump is simple in structure and reliable in performance.
Description
Technical field
The utility model relates to a kind of automobile cab switching mechanism, especially hydraulic hand-pump.
Background technique
At present; The hydraulic turnover mechanism that domestic all basically commercial-vehicle cab upsets are all adopted; This mechanism is made up of hand () hydrodynamic press pump, hydraulic lifting cylinder and oil pipe etc.; Through machinery () can be converted into hydraulic pressure kinetic energy, and then be converted into mechanical energy, thereby realize the lifting and the falling of operator cabin.As shown in Figure 1; The driver's cab turnover of existing technology comprises the pump housing 1, plunger piston assembly 7, reversing handle 6, reversing valve complement 5, lifting oil nozzle 3, decline oil nozzle 2 and rocking arm 8 with hydraulic hand-pump; The lifting oil nozzle 2 of hand () the hydrodynamic press pump of the car load factory of technology all is down with decline oil nozzle 3 now; Link with high-pressure oil pipe and hydraulic lifting cylinder lifting oil nozzle and decline oil nozzle then, this structure has taken additional space in the automobile chassis space, under the pavement behavior condition of severe; Can cause oil nozzle to be collided with, thereby cause the driver's cab turnover hydraulic system to damage and cisco unity malfunction by obstacle.
The model utility content
The utility model purpose is to overcome the deficiency that above-mentioned existing technology exists, and provides a kind of lifting oil nozzle and decline oil nozzle to be not easy to damage, and simple in structure, processing technology is simplified, and the driver's cab turnover of superior performance is used hydraulic hand-pump.
The technological scheme that technical problem adopted that the utility model solves is:
Provide a kind of driver's cab turnover to use hydraulic hand-pump; Comprise the pump housing, plunger piston assembly, reversing handle, reversing valve complement, lifting oil nozzle and decline oil nozzle; Pump housing side is provided with the installation tapped hole; It is characterized in that lifting oil nozzle and decline oil nozzle are located at the side of the pump housing, be positioned on same with the installation tapped hole of the pump housing.
During practical implementation; The decline oil nozzle is located at the end of reversing valve complement, with the coaxial of reversing valve complement, the reversing valve complement rotatingshaft be axially arranged with axial oil outlet; Its axial oil outlet output channel end is provided with obstruction, and the lifting oil nozzle is connected with axial oil outlet output channel.
It is to be used for being connected with vehicle frame that tapped hole is installed; Installation tapped hole on lifting oil nozzle and the decline oil nozzle and the pump housing is in the same side; And to spring up direction vertical with plunger; The lifting oil nozzle is parallel with the reversing valve complement rotation axis, and the axis coaxle of wherein descend oil nozzle center line and reversing valve complement rotatingshaft is provided with a radially oil outlet between decline oil nozzle center line and reversing valve complement; The utility model reversing valve complement is provided with radially an oil outlet and an axial oil outlet altogether.
The beneficial effect of the utility model is:
1, because lifting oil nozzle and decline oil nozzle are in the pump housing by the tapped hole side is installed, avoided badly being knocked the bad oil mouth, thereby caused the driver's cab turnover hydraulic system to damage by obstacle because of pavement behavior
When 2, adopting the utility model mounting structure; Pump housing processing is simpler; And selector valve has only radially an oil outlet and an axial oil outlet; Oil circuit between the selector valve and the pump housing only need be controlled the radially sealing at oil outlet place and get final product, and makes whole hand-hydraulic pump structure simpler, more reliable performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the utility model embodiment's a structural representation.
Among the figure: 1, the pump housing 2, decline oil nozzle 3, lifting oil nozzle 4, stop up 5, reversing valve complement 6, reversing handle 7, plunger piston assembly 8, rocking arm A, radially oil outlet B, axially oil outlet C, tapped hole is installed.
Embodiment
Among Fig. 2, a kind of driver's cab turnover is used hydraulic hand-pump, and it comprises the pump housing 1, plunger piston assembly 7, reversing handle 6, reversing valve complement 5, lifting oil nozzle 3, decline oil nozzle 2 and rocking arm 8; The pump housing 1 side is provided with vehicle frame and links with two installation tapped hole C; Tapped hole C are installed are positioned at the same side for two on lifting oil nozzle 3 and the decline oil nozzle 2 and the pump housing 1; And it is vertical with plunger piston assembly 7 moving direction; Parallel with reversing valve complement 5 rotation axiss, oil nozzle 2 center lines and reversing valve complement 5 coaxial wherein descend; Reversing valve complement 5 has only radially an oil outlet A and an axial oil outlet B, and axially oil outlet B output channel following being provided with of leading to the pump housing 1 stops up 4, and lifting oil nozzle 3 is connected with axial oil outlet B output channel.
The utility model has been avoided badly being knocked bad lifting oil nozzle 3 and decline oil nozzle 2 by obstacle because of pavement behavior, thereby has been caused the driver's cab turnover hydraulic system to damage because lifting oil nozzle 3 is in the pump housing by tapped hole A side is installed with decline oil nozzle 2.After adopting this mounting structure simultaneously, reversing valve complement 5 has only radially an oil outlet A and an axial oil outlet B, and the oil circuit between the reversing valve complement 5 and the pump housing 1 only need be controlled the radially sealing at oil outlet A place and get final product.To have structure with hydraulic hand-pump simpler for the related driver's cab turnover of this model utility in a word, the advantage of more reliable performance.
The same existing technology of the utility model embodiment's basic functional principle is not done narration at this.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, and any structure after simple transformation on the utility model basis all belongs to the protection domain of the utility model.
