Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency rescue, in particular to an emergency rescue and rescue vehicle. BACKGROUND

[0002] The rescue trailer is the key equipment for emergency rescue and rescue, and the core role is reflected in multidimensional support: first, quickly drag away the fault or accident vehicle, remove the on-site obstacles, avoid secondary accidents, and ensure the smoothness of the road; second, transport excavators, breaking equipment and other heavy rescue tools, tents, medicines and other emergency materials to open up the "last mile" of material transportation; third, adapt to special scenes such as off-road and water, undertake customized tasks such as righting accident vehicles and transporting dangerous goods. As the link of the emergency system, it connects the front and rear rescue links, improves the overall response efficiency, and is an important support for controlling risks and ensuring the smooth progress of rescue.

[0003] With the development of new energy technology, the rescue trailer can directly power the equipment on the chassis through the setting of the on-board battery, thereby achieving efficient operation while saving energy expenditure.

[0004] In the actual use process of the new energy rescue trailer, first, the battery is used to drive the trailer board to be inclined and removed from the base, then the connecting ring at one end of the steel wire rope on the trailer board is connected with the towing hook at the front end of the vehicle to be rescued, and finally the steel wire rope is wound, so that the vehicle can be towed to the trailer board. Because the towing hook of the vehicle to be rescued is located on one side of the vehicle, when the steel wire rope pulls the vehicle, the pulling force of the steel wire rope during the towing process will produce a horizontal component, which will cause the vehicle to deviate to one side. Especially the accident vehicle will deviate from the symmetric position due to the deformation of the vehicle body, thereby reducing the towing stability and safety of the vehicle to be rescued, and further affecting the rescue efficiency of the vehicle.

[0033] Working principle: When rescuing a vehicle that cannot move normally for some reason, the rescue vehicle is first moved to the front side of the vehicle to be rescued, and then the driving mechanism on the chassis 101 is used to tilt the trailer board 102 out, and one end of the trailer board 102 is moved close to the vehicle to be rescued. After the trailer board 102 is tilted out, the wire rope 104 can be pulled to move the wire rope 104 out of the winding box 103; In the process of pulling the steel wire rope 104, the two sets of correction rollers 303 will be driven to rotate synchronously under the action of friction, and under the limiting action of the two sets of correction rollers 303 and the guide roller 305, the steel wire rope 104 between the two rectangular frames 301 is in a vertical state and will not be changed by the moving direction of the steel wire rope 104. Therefore, in the process of driving the correction roller 303 to rotate during the pulling of the steel wire rope 104, the transmission member 704 (the transmission member 704 is a combination of a transmission wheel and a transmission belt) will synchronously drive the rotating shaft 701 to rotate, and then drive the gear 702 at one end of the rotating shaft 701 to rotate, and then drive the detection ring 501 to rotate under the meshing transmission action of the gear 702 and the end face gear ring 703; In the process of rotating the detection ring 501, the detection roller 503 will be pushed by the extrusion assembly to abut against the surface of the steel wire rope 104, and then rotate in the process of rotating the detection roller 503, thereby improving the comprehensiveness of the surface damage detection of the steel wire rope 104; When the surface of the steel wire rope 104 is damaged in the process of rotating the detection roller 503, the surface of the steel wire rope 104 will appear a convex point under the breaking of the steel wire, and then the detection roller 503 in contact with the convex point will move close to the detection ring 501 under the pushing action of the convex point, and in the process of moving the detection roller 503 close to the detection ring 501, the two first T-shaped rods 601 will be pushed to move close to the marker ring 802, and when the two first T-shaped rods 601 move with the driving plate 1001 on one side of the marker ring 802, the driving plate 1001 will be pushed to move close to the marker ring 802 under the interaction force of the inclined groove 1002 and the guiding action of the telescopic assembly; In the process of moving the driving plate 1001 close to the marker ring 802, the air bag 805 will be extruded, and then the pigment in the discharge pipe 803 will be sprayed from the L-shaped pipe 804 to the surface of the steel wire rope 104 under the action of the air pressure under the extrusion action and the one-way conduction action of the two one-way valves 807, thereby marking the surface damage of the steel wire rope 104, so as to realize the damage detection of the steel wire rope 104 and mark the surface damage of the steel wire rope 104, thereby providing a convenient and fast search for the staff to check and confirm the damage of the steel wire rope 104, thereby improving the effectiveness of the detection of the steel wire rope 104; With the continuous pulling of the steel wire rope 104, when the traction hook 105 at one end of the steel wire rope 104 moves to the front end of the vehicle, the traction hook 105 can be connected with the traction connection of the vehicle, and after the traction hook 105 is connected with the traction vehicle, the steel wire rope 104 can be wound by the winding box 103. In the process of winding the steel wire rope 104, the vehicle to be rescued will be continuously dragged to the trailer plate 102 under the traction of the steel wire rope 104, and in the process of the vehicle to be rescued moving to the trailer plate 102, since the traction position of the vehicle to be rescued is located on one side of the vehicle, when the vehicle is pulled by the steel wire rope 104, the lateral component force of the pulling force of the steel wire rope 104 during the dragging process will cause the vehicle to be rescued to deviate to one side, especially the accident vehicle will deviate from the symmetric position due to the deformation of the vehicle body, and when the vehicle to be rescued deviates, the staff can drive the lead screw 403 to rotate by starting the motor 404, and then drive the two rectangular frames 301 to move to the side opposite to the deviation direction of the vehicle head of the vehicle to be rescued under the threaded engagement transmission action of the lead screw 403 and the threaded sleeve and the guiding action of the moving rod 401 and the moving plate 402, and then in the process of the two rectangular frames 301 moving to the side opposite to the deviation direction of the vehicle head of the vehicle to be rescued, the two sets of correction rollers 303 are used to pull the steel wire rope 104, so that the deviated vehicle head is gradually corrected under the action of the pulling force. After the deviated vehicle head is corrected, the two rectangular frames 301 need to be moved by using the moving assembly, so that the steel wire rope 104 is perpendicular to the vehicle. At this time, the vehicle can be continuously pulled, and in the process of pulling, the pulling direction of the steel wire rope 104 is adjusted according to the deviation of the vehicle, so that the risk of the vehicle to be rescued tilting and deviating on the trailer plate 102 is reduced while the vehicle to be rescued is dragged to the trailer plate 102, thereby improving the stability and safety of the dragging of the vehicle to be rescued, thereby ensuring the rescue efficiency of the vehicle.
