Adjustable non-nail chock

Abstract

The invention relates to fixing equipment for railway transportation wheel type equipment and belt type equipment, namely, an adjustable non-nail chock. The adjustable non-nail chock comprises an anti-skidding seat. Two ends of a beam are inserted in the anti-skidding seat and slide in the anti-skidding seat. The beam is supported by four connecting rods at two sides. A pair of connecting boards are connected between the four connecting rods at the two sides. A screw rod is connected between the two connecting boards. Each shovel type bottom chock comprises two side upright boards and a shovel board connected between the two side upright boards. The front ends of the two side upright boards are respectively provided with a slope. The shovel type bottom chocks are inserted in two outer sides of the anti-skidding seat through the two side upright boards. According to the adjustable non-nail chock, nails are not required for fixing, pretightening force is adjustable, disassembly and assembly are convenient, speed is high and safety property is good. When a wheel receives large impact force and the adjustable non-nail chock receives the same impact force, a gap can not generated. The adjustable non-nail chock is reusable, long in using time and capable of reducing using cost.

Description

technical field [0001] The invention relates to a fixing device for railway transportation of wheeled equipment (vehicles) and crawler equipment (tanks, bulldozers), that is, an adjustable nailless wheel stop. Background technique [0002] In the prior art, wheel chocks are used to fix tires when the wheeled equipment is transported by rail. At present, the wheel chocks mainly include triangular wood and iron-plastic triangular wheel chocks. The disadvantages are: [0003] 1. The original triangular wood and iron-plastic triangular wheel chocks are non-adjustable in structure and fixed with nails. Vehicle-mounted reinforcement of wheeled equipment can only be carried out on wooden floor flat cars, that is to say, wheeled equipment cannot be transported on iron floor flat cars or containers at present. For wheels with small wheel diameters, installation is very inconvenient, especially when the working space Hours cannot be reinforced with iron-plastic triangular wheel choc...

AI Technical Summary

Problems solved by technology

Wheeled equipment can only be reinforced on a wooden floor flat car, that is to say, wheeled equipment cannot be transported on an iron floor flat car or container at present. For wheels with small wheel diameters, it is very inconvenient to install, especially when the work space Hours cannot be reinforced with iron-plastic triangular wheel chocks

[0004]2. It takes time and effort to dismantle the original triangular wood and iron-plastic triangular wheel chocks

Affect the mobility and rapid response capabilities of the troops

[0005]3. During the use of triangular wood and iron-plastic triangular wheel chocks, when a large impact is received, a certain distance is formed between the wheel and the chock, and the impact force is eliminated After that, the gap cannot be eliminated, which affects the safety of use

[0007] For crawler mobile equipment, square wood and nails are currently used for reinforcement, and crawler mobile equipment can only be transported on a wooden floor flat truck
