Abstract

The invention discloses a trailer frame structure for coal mine collection, which comprises a frame body, a vehicle body installation groove is arranged on the top of the vehicle frame body, and a hollow groove is arranged at the bottom of the vehicle body installation groove. There are four ends arranged symmetrically in the hollow groove, and a draw bar is fitted between the two opposite ends, and the two ends of the draw bar pass through the ends and the frame body in sequence , the end of the traction rod passing through the frame body is provided with a traction hole, two mounting plates are symmetrically disposed in the hollow groove, and two guide wheels are symmetrically disposed at the bottom of the mounting plate, so Bolts are fitted between the guide wheels and the mounting plate; the device carries the trailer body through the frame mounting groove to prevent the trailer body from being directly subjected to traction force, and the device bears the tension through the two ends of the traction rod to improve Capacity, increase the overall bearing capacity of the device, the structure of the device is relatively simple, and the cost is relatively low.

Description

technical field [0001] The invention relates to a trailer frame structure for coal mine collection. Background technique [0002] After the coal ore is collected, it needs to be towed to the outside of the coal mine by a trailer. The trailer in the prior art is provided with several sections, and the several sections of the trailer are connected by simple steel cables. The car body of the trailer is damaged, and it does not have the function of overload protection, which reduces the service life of the trailer. [0003] Based on the above problems, it is necessary to provide a trailer frame structure that can replace the trailer for stress and prolong the service life. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a trailer frame structure for coal mine collection. This device carries the trailer body through the frame mounting groove, so as to avoid the trailer body from being directly subjected to traction f...
