Description

Technical Field

[0001] This utility model relates to the technical field of mining machinery and equipment, and in particular to a connection device for the rear frame and axle of an underground trackless vehicle. Background Technology

[0002] In underground mining environments, trackless vehicles play a crucial role in material transport and personnel transport. The connection between the rear frame and the axle is a key component ensuring stable vehicle operation. However, some existing connection devices suffer from insufficient structural strength. Due to the complex underground conditions, vehicles are frequently subjected to bumps and impacts during operation, which can easily lead to loosening of the connections, affecting vehicle safety and stability. Furthermore, some connection devices are cumbersome to install and maintain, requiring significant manpower and time, hindering efficient mining operations. In addition, existing connection devices have inadequate buffering designs between the axle and the rear frame, failing to effectively absorb vibrations during operation. This not only reduces the lifespan of vehicle components but also affects driver comfort. Utility Model Content

A front baffle support plate is installed at the rear bottom of the rear frame, and a front baffle base plate is installed at the bottom of the front baffle support plate. A rear baffle is installed at the rear bottom of the rear frame, located behind the front baffle support plate. A rear baffle base plate is located at the bottom of the rear baffle, and a rear baffle support plate is located on the side of the rear baffle. A support base plate connects the bottom of the front baffle base plate and the rear baffle base plate. A threaded hole is provided through the support base plate at the position corresponding to the connection hole. The axle is installed below the rear end of the rear frame. The upper surface of the axle is connected to the rear bottom of the rear frame, the front surface is connected to the front baffle support plate, the rear surface is connected to the rear baffle, and the bottom end is connected to the top of the support base plate. Fastening bolts pass sequentially through the connection hole of the rear frame, the axle, and the support base plate to connect the rear frame and the axle.

[0006] A pad is provided at the bottom rear end of the rear frame at the position corresponding to the connection hole, and a threaded hole is provided through the pad at the position corresponding to the connection hole.

[0007] Pads are provided at both ends of the bottom of the pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] Through the coordinated action of the front baffle support plate, front baffle bottom plate, rear baffle, rear baffle bottom plate, rear baffle support plate and support base plate, a stable support structure is formed, which greatly enhances the connection strength between the rear frame and the axle. It can effectively cope with the bumps and impacts caused by the complex road conditions underground, and ensure the safety and stability of vehicle driving.

[0010] The connection device of this utility model has a reasonable structural design and the installation positions of each component are clear and specific, which reduces the operational difficulty in the installation and maintenance process, saves manpower and time costs, and is conducive to the efficient production operation of the mine.

[0011] The pads at both ends of the bottom of the pad can play a certain role in cushioning, effectively absorbing vibrations during vehicle operation, extending the service life of vehicle parts, and improving the driver's operating comfort. Attached Figure Description
