Detection and homing device of tank type vehicle retaining device

Abstract

The invention discloses a detection and homing device for a tank type vehicle retaining device. The detection device comprises a vehicle stopping connector and a vehicle stopping homing device. The number of the vehicle stopping connectors is two, and the vehicle stopping connectors can be placed on the vehicle stopping homing device. The vehicle stopping connector comprises a retaining device body and a connection detection assembly. The connection detection assembly comprises a first wireless communication module, a connection detection module and a first magnet. The vehicle stopping homing device comprises a homing detection assembly, and the homing detection assembly comprises a second wireless communication module, a homing detection module and a second magnet; and the vehicle stopping connector and the vehicle stopping homing device realize communication interconnection through the first wireless communication module and the second wireless communication module. The detection device can conveniently detect whether the retaining device is placed in place or not when in use and whether the vehicle stopping connector is reset or not after loading and unloading are completed, if violation operation is carried out, an alarm is triggered, signals are sent to an on-site loading and unloading system, interlocking control is carried out, and the loading and unloading process is stopped, so that the safety and the working efficiency during use are improved.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a detection and return device for a tank-type vehicle backstop. Background technique [0002] Backstops are also called car stoppers, triangular wood, anti-skid triangular wood, etc. It belongs to the anti-sports car device, which is generally installed under the wheel. On the one hand, it restricts the vehicle to stay in the specified position, and on the other hand, it is used to prevent sports car accidents. It is often used in conjunction with carts, dumpers, climbing cars and tankers. [0003] In the field of petrochemical industry, tank trucks are often used to transport petrochemical products. When loading and unloading dangerous goods (oil products, chemicals) storage and transportation tank trucks, backstops should be used to prevent the vehicles from moving. According to safety requirements, before loading and unloading the tanker, the driver needs to place the ba...

Problems solved by technology

However, in the actual use process, the technicians found that the detection device has a heavy structure and weight, which increases the difficulty of operation; Pull out the steel wire rope in the reel, and check whether the backstop is in place according to the length of the pullout. However, after the backstop is in place, the steel wire rope will be pulled out for a distance of 3-5 meters, and the steel wire rope is very thin, so the on-site personnel do not pay attention You will be tripped and there are potential safety hazards; the length of the wire rope in the reel is about 5 meters, so there are high requirements for the installation position of the reel. If it is too close, the backstop will not be detected under the wheel. If it is far away, the backstop cannot be placed under the wheel, and because the detection principle is to determine that the backstop is in place after pulling out a certain distance, it is impossible to detect whether the backstop is accurately placed under the wheel; due to this detection principle, The backstop must be moved more than 3 meters, and the backstop must be returned after use. This process is time-consuming and laborious, and the work efficiency is low; the vehicle must drive into the detection range of the device, which increases the difficulty of loading and unloading. There are certain limitations
