A boarding bridge device for vehicle-mounted remote control non-road walking equipment

Abstract

The invention discloses a vehicle-mounted boarding bridge device for remotely controlling non-road walking equipment. The device comprises an installation bottom plate, a bridge plate, a bridge plate telescopic hydraulic cylinder, a bridge plate variable amplitude hydraulic cylinder, a hydraulic power source and a control component. The bridge plate comprises a foundation bridge plate and at least one telescopic bridge plate. The foundation bridge plate and the telescopic bridge plates are further provided with bridge plate side baffles which are arranged in a left-right symmetrical mode, extend out of the upper surfaces of the foundation bridge plate and the telescopic bridge plates in the front-back direction and are each of a vertical plate structure. The distance between the bridge plate side baffles is matched with the wheel rim distance in the left-right direction of a fire-fighting robot, and the bridge plate side baffles of the foundation bridge plate are staggered with those of the telescopic bridge plates in the left and right direction. The vehicle-mounted boarding bridge device for remotely controlling the non-road walking equipment can remotely control the non-road walking equipment to stably, rapidly and automatically enter a compartment any time any where, then, the purpose of rapid response is achieved, and the vehicle-mounted boarding bridge device is particularly applicable to boarding for remote control non-road walking equipment such as large-power fire-fighting robots, smoke exhaust robots and detection robots.

Description

technical field [0001] The invention relates to a boarding bridge device, in particular to a boarding bridge device for vehicle-mounted remote control non-road walking equipment suitable for remote control of non-road walking equipment getting on and off, and belongs to the field of special equipment loading and unloading transportation. Background technique [0002] For the transportation of non-road walking equipment with crawlers such as excavators, transport trucks are usually used for transportation. However, due to the high distance between the chassis of the truck and the ground, it is difficult to load and unload the walking equipment. The existing loading and unloading methods usually adopt the following three methods: 1. The loading and unloading site adopts a fixed or mobile loading platform. The transport truck backs up to the fixed loading platform for docking, or moves the mobile loading platform to the transport truck for docking. Loading and unloading, this m...

[0002] For the transportation of non-road walking equipment with crawlers such as excavators, transport trucks are usually used for transportation. However, due to the high distance between the chassis of the truck and the ground, it is difficult to load and unload the walking equipment. The existing loading and unloading methods usually adopt the following three methods: 1. The loading and unloading site adopts a fixed or mobile loading platform. The transport truck backs up to the fixed loading platform for docking, or moves the mobile loading platform to the transport truck for docking. Loading and unloading, this method is limited by the loading and unloading location, and it cannot be loaded and unloaded anytime and anywhere, and the operation is more troublesome, time-consuming and laborious; 2. Use the vehicle-mounted hydraulic tail lift for loading and unloading, and the hydraulic tail lift uses vertical lifting to load the vehicle The equipment is lifted to be flush with the upper plane of the transport truck chassis so that the loading and unloading personnel can easily load and unload. This method is mainly used for loading and unloading of goods, but for walking equipment, due to its load capacity and the size of the tail lift platform, it is only suitable for weight and loading and unloading of smaller-sized walking equipment; 3. The loading and unloading of the vehicle-mounted boarding bridge is a method that can form an inclined plane between the truck chassis and the ground. Most used

[0003] The existing vehicle boarding bridge can realize fast boarding and disembarkation for non-road walking equipment such as excavators driven manually, but for large-scale remote non-road walking equipment such as fire robots, smoke exhaust robots, and detection robots, due to the robot Operators usually do not control on the equipment, so the control of its walking direction is often carried out through visual inspection or monitoring screen, which makes it difficult to control the accurate traveling direction of this kind of remote control non-road walking equipment when boarding the vehicle using the boarding bridge, and the direction is not grasped. Accuracy or poor control of the driving speed can easily lead to side slipping and damage caused by falling. Therefore, the existing large-scale remote control non-road walking equipment usually does not use the way of boarding bridges but the way of hoisting. However, the way of hoisting is limited by the hoisting space. restrictions, and the hoisting process is time-consuming, it is not suitable for large-scale remote control off-road walking equipment such as fire-fighting robots that require quick response; in addition, high-power fire-fighting robots, smoke exhaust robots and other remote control off-road walking Functional limitations result in its own weight (about 2t) and low climbing ability (about 20°). Even if a boarding bridge is used, the inclination angle of the boarding bridge must be smaller than the climbing angle of the equipment. The length of the axle is too long, the vehicle is difficult to carry, and the loading and unloading takes a long time; moreover, if the high-power remote control non-road walking equipment fails to walk during the boarding process, the boarding cannot be completed
