Abstract
Description
Technical Field
[0001] The utility model relates to a device capable of reducing the wear of a balance beam pin shaft, and belongs to the technical field of balance beam pin shafts. Background Art
[0002] A trailer is a vehicle towed by a car but without its own power drive device. It is a combination of a car (truck or tractor, forklift) and one or more trailers. The truck and tractor are the driving sections of the car train, called the main car. The balance beam pin is the part used to connect the balance beam and the trailer. When some existing pins are used, a solid structure will be adopted to enhance the stability of the connection.
[0003] There are still some problems in the use of the existing balance beam pin device. For example, during use, the balance beam pin constantly shakes at the connection of the semi-trailer, which increases the friction between the surface of the mounting column and the connection when it is squeezed, thereby causing it to wear faster. At the same time, a nut is fixedly connected to the outside of the mounting column. When the nut needs to be replaced, it is more troublesome to replace it because the nut is welded to the outside of the mounting column. Utility Model Content
[0004] The purpose of the utility model is to provide a device that can reduce the wear of the balance beam pin shaft. The utility model has a simple structure and is easy to use. When the balance beam pin shaft shakes, it can lubricate the installation column and the connection, thereby reducing wear, and can easily replace the nut on the outside of the installation column to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] The cam is secured to the outer wall of the oil pump, and the cam is secured to the outer wall of the oil pump with a spring, and the cam is secured to the outer wall of the oil pump with a spring.
[0007] Furthermore, a threaded hole is provided inside the mounting column, a rotating tube is fixedly connected to the outer side of the clamping plate, a screw rod is rotatably connected inside the rotating tube, and a rotating cover is fixedly connected to the outer side of the screw rod.
[0008] Furthermore, the oil bag is installed inside the beam pin shaft body through a stabilizing plate and a No. 1 return spring, and the movable ring is symmetrically distributed on the outside of the beam pin shaft body.
[0009] Furthermore, the extrusion rod is located inside the beam pin shaft body away from the force-bearing cover, and the No. 1 return spring is located outside the extrusion rod.
[0010] Furthermore, the oil spray cover is located on the outside of the mounting column, and one end of the oil inlet pipe away from the oil bag is fixedly connected to the outside of the beam pin shaft body.
[0011] Furthermore, the threaded holes are evenly distributed inside the mounting column, and the rotating tubes are evenly distributed outside the clamping plate.
[0012] Furthermore, the screw is rotatably connected to the inside of the rotating tube through a rotating cover, and one end of the screw away from the rotating cover is threadedly connected to the inside of the threaded hole.
[0013] The beneficial effects of the utility model are:
[0014] (I) The utility model provides a support seat, and a beam pin shaft body is fixedly connected to the outer side of the support seat. When the beam pin shaft body shakes during operation, the force cover on the outer side thereof is squeezed, so that the force cover drives the squeezing rod to move inside the movable circle. The oil bag inside the beam pin shaft body is squeezed by the movement of the squeezing rod, so that the lubricant inside the oil bag is sprayed to the outer side of the mounting column through the oil outlet pipe and the oil spray cover, and a No. 1 return spring is fixedly connected to the outer side of the squeezing rod. Therefore, the squeezing rod can intermittently squeeze the oil bag. When the lubricant flows to the outer side of the mounting column, the friction between the mounting column and the connection can be reduced, thereby reducing the wear of the beam pin shaft body. By opening the sealing cover, the lubricant can be added to the inside of the oil bag through the oil inlet pipe.
[0015] (ii) The utility model provides a beam pin shaft body, and a mounting column is fixedly connected to the outer side of the beam pin shaft body, and is mounted on the outer side of the mounting column through a clamping plate and a nut. When the nut needs to be replaced, the screw rod is driven to rotate inside the rotating tube through a rotating cover, so that the bottom of the screw rod moves out of the threaded hole inside the mounting column. At this time, the mounting column can be moved out from the inside of the clamping plate, thereby achieving the effect of facilitating the replacement of the nut. BRIEF DESCRIPTION OF THE DRAWINGS
