Description

Technical Field

[0001] The utility model relates to the technical field of mounting brackets, in particular to a cab lifting oil pump bracket. Background Art

[0002] The lifting oil pump is usually used to transport the hydraulic medium of the hydraulic device. The oil pump of the hydraulic device at the bottom of the cab is usually installed near the bottom of the cab. After searching, the Chinese patent authorization number CN203306122U discloses a cab lifting oil pump bracket. Although the bracket can cleverly install the lifting oil pump to avoid occupying the space outside the frame, the engine of the truck is usually installed near the cab. The engine will vibrate when it starts, and the vibration will be transmitted to the oil pump through the frame structure. When the oil pump is vibrated for a long time, it will affect the service life of the oil pump. At the same time, it will cause the connection between the oil pump and the pipeline to be loosened due to long-term vibration, which will pose a safety hazard. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a cab lifting oil pump bracket, which solves the problem in the background technology that the existing oil pump bracket will affect the service life of the oil pump when subjected to vibration for a long time, and will cause the connection between the oil pump and the pipeline to loosen due to vibration for a long time.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a cab lifting oil pump bracket, including a mounting frame body, a first spring, a lifting plate and a slide groove, a fixing block is welded at one end of the top of the mounting frame body, and the bottom of the fixing block is fixed to the frame surface by mounting bolts, two first dampers are installed at the bottom of the mounting frame body, a first spring is sleeved on the outside of the first damper, one end of the top of the first damper is welded to the bottom of the lifting plate, a slide plate is arranged above the lifting plate, an oil pump body is arranged on the top of the slide plate, and the bottom of the oil pump body is fixed to the top of the slide plate by bolts.

[0005] Preferably, the bottom of the mounting frame body is in an L-shaped structure, and the bottom end of the mounting frame body is welded to one end of the bottom of the limiting rod, and the outer wall of the limiting rod is in sliding contact with the four ends of the lifting plate, which is conducive to enabling the lifting plate to slide up and down through the limiting rod when it is vibrated, and then helps to keep the lifting plate level and improve the stability of the bracket.

[0006] Preferably, a groove is provided on the top surface of the lifting plate, and a ball is embedded in the groove on the top surface of the lifting plate. The ball is in sliding contact with the bottom of the skateboard. The ball helps to improve the smoothness of sliding of the skateboard when it is shaken in the horizontal direction, thereby reducing the friction at the bottom of the skateboard, thereby extending the service life of the skateboard.

[0007] Preferably, a connecting block is welded on the top of the lifting plate, two second dampers are welded on one side of the connecting block, a second spring is mounted on the outside of the second damper, and the other end of the second damper is rotatably connected to a roller, and the roller is located inside the slide groove, which helps the second damper to remain connected to the slide plate when the lifting plate moves in the horizontal direction, which helps the lifting plate to buffer multiple horizontal direction shakes, and helps to further improve the stability of the bracket.

[0008] Preferably, the slide groove is provided on the outer surface of the sliding plate, and the cross section of the slide groove is a T-shaped structure, and the interior of the slide groove is slidably connected to the roller.

[0009] The utility model provides a cab lifting oil pump bracket, which has the following beneficial effects:

[0010] (1) A cab lifting oil pump bracket, wherein the bracket is installed on the frame at the bottom of the cab by installing a fixing block, so that when the vehicle engine is started, the vibration is transmitted to the mounting bracket body through the frame, so that the mounting bracket can reduce the vibration of the lifting plate through the first damper and the first spring at the bottom of the lifting plate, which is beneficial to the effect of reducing the vibration of the oil pump body installed above the lifting plate, thereby greatly reducing the vibration of the oil pump body, which is beneficial to protecting the oil pump body.

[0011] (2) In the cab lifting oil pump bracket, when the oil pump is subjected to horizontal shaking, the oil pump body will move horizontally through the slide plate at the bottom, and then the slide bar will slide through the ball bearing at the bottom. At the same time, the outer side of the slide bar will squeeze the outer second damper and the second spring. The second damper and the second spring are helpful for the oil pump body to reduce the vibration in the horizontal direction, thereby helping to further improve the shock absorption effect.

[0012] This solves the problem that the service life of the oil pump is affected when the existing oil pump bracket is subjected to vibration for a long time, and the problem that the connection between the oil pump and the pipeline is loosened due to vibration for a long time is also solved.
