Description

Detachable bracket trailer for coal mine Technical Field The invention relates to the field of underground trackless rubber-tyred transport vehicles of coal mines, in particular to a detachable bracket trailer for coal mines. Background The support trailer is a key auxiliary transportation device for transporting large-scale and heavy equipment such as a hydraulic support and the like under a coal mine. In the prior art, a support carrier or two scooters are commonly used to cooperatively transport a hydraulic support. However, the support carrier has single function and lower working efficiency, and the two scooters have high requirement on synchronism during transportation, and the whole carrier has longer size and large occupied space. More importantly, in many coal mines, the cage is limited in size and cannot accommodate an integral bracket trailer or a bracket carrier to go into the well, so that the vehicle cannot work underground, and the production efficiency is severely restricted. Therefore, it is necessary to design a detachable bracket trailer for coal mines to solve the problems in the prior art. Disclosure of Invention The invention aims to provide a detachable bracket trailer for a coal mine. The invention provides a detachable bracket trailer for coal mines, which comprises the following components: the left side and the right side of the front assembly are respectively provided with a left assembly and a right assembly; The left assembly pin penetrates through the connecting holes of the front assembly and the left assembly and is used for detachably and fixedly connecting the front assembly and the left assembly; the right side assembly pin penetrates through the connecting holes of the front assembly and the right assembly and is used for fixedly connecting the front assembly and the right assembly in a detachable mode. According to the detachable bracket trailer for the coal mine, the guide sleeves are arranged in the connecting holes of the left component and the right component, and the outer walls of the guide sleeves are tightly attached to the hole walls of the connecting holes. According to the detachable bracket trailer for the coal mine, the lubricating bearing groups are arranged between the left side assembling pin, the right side assembling pin and the inner wall of the corresponding guide sleeve. According to the detachable bracket trailer for the coal mine, the lubricating bearing group comprises two short self-lubricating bearings and two long self-lubricating bearings, the two short self-lubricating bearings are arranged on two sides of the guide sleeve, and the two long self-lubricating bearings are arranged between the two short self-lubricating bearings. According to the detachable bracket trailer for the coal mine, axial gaps are arranged between the short self-lubricating bearing and the adjacent long self-lubricating bearing and between the two long self-lubricating bearings, and the axial gaps form grease storage grooves for storing lubricating grease. According to the detachable bracket trailer for the coal mine, the limiting baffles are arranged at the two ends of the left side assembling pin and the right side assembling pin. The detachable bracket trailer for the coal mine, provided by the invention, further comprises a pressing plate, wherein the pressing plate is detachably connected to the front assembly and abuts against the limit baffle. Compared with the prior art, the application has the beneficial effects that: According to the invention, the left assembly, the right assembly and the front assembly are detachably and fixedly connected through the left assembly pin and the right assembly pin respectively, so that the whole bracket trailer is divided into three modules, and the arrangement of the modularized structure is convenient for disassembling and assembling the bracket trailer, and improves the working efficiency of carrying the bracket and other equipment.
