Problems solved by technology

If the faulty vehicle is a heavy vehicle, and the heavy vehicle is in a complex environment such as silt, sand sink or ditch, the existing towing ambulance often cannot reliably support the towing and rescue due to its insufficient traction and no supporting reaction force. Vehicles, in the process of towing and rescue, it often happens that the towed and rescued vehicle is overturned due to the heavy weight of the rescued vehicle, causing safety hazards to the towed and rescued vehicles, and the towing and rescue operation cannot be completed well

Embodiment 1

[0042] like Figure 1 to Figure 5 As shown, it is an exemplary embodiment of the rescue device for heavy-duty wheeled vehicles provided by the present invention. In this exemplary embodiment, a tow-and-rescue device for heavy-duty wheeled vehicles comprises a base frame 1, a Mast 2, support arm 3, main winch 4, auxiliary winch 5, lifting cylinder 7, turning cylinder 8.

[0043] The base frame 1 is installed above the frame between the two rear axle wheels at the rear of the towed vehicle through the saddle 18, and the auxiliary winch 5 is installed above the front of the base frame 1, which can provide the towed vehicle with a traction force of 176 kN , the overturning oil cylinder 8 is installed at the rear of the base frame 1, and a towing rope winch 9 is installed on one side of the rear part of the base frame 1. The towing rope winch is used to assist the main winch 4 and the auxiliary winch to release the wire rope. A turning block shaft 14 is welded on the rear end of t...

Embodiment 2

[0060] A tow rescue device for heavy-duty wheeled vehicles, its structure and layout are the same as those of Embodiment 1, and specifically, it also includes a first pulley 19, the first pulley 19 is installed on the outer side of the front end of the support arm 3, the main and auxiliary pulleys 19. The wire rope of the winch goes around the first pulley 19 and is connected to the rescued vehicle.

[0061] The following takes the side drag operation as an example to describe the operation process:

[0062] When there is insufficient space at the rescue site and it is impossible to deploy the rear drag, side drag can be used.

[0063] The steps of side towing operation are as follows:

[0064] 1) Park the tow truck in front of the rescued vehicle, the center line of the frame is perpendicular to the center line of the rescued vehicle, and unfold the tow rescue device, such as Figure 11 shown.

[0065] 2) Install the first pulley 19 on the outer side of the front end of th...

Embodiment 3

[0070] A tow rescue device for heavy-duty wheeled vehicles, the structure and layout of which are the same as those of Embodiment 1, and specifically include a chain 20 and a second pulley 21, one end of the chain 20 is connected to both sides of the support arm 3 , the other end of the chain is connected to the second pulley 21, the wire rope of the auxiliary winch 4 bypasses the fixed pulley 10 and the second pulley 21 and is connected to the rescued vehicle. The center line of the auxiliary winch is basically parallel, such as Figure 16 As shown, in this way, the stress of the rescued vehicle can be effectively improved during the towing operation.

[0071] The operation method and process are the same as those in Embodiment 1, and will not be repeated here.

[0072] The towing and rescue device provided by the present invention operates through the main and auxiliary winches at the same time, so as to provide sufficient traction force for it. It supports the reaction fo...

Abstract

The invention relates to a dragging and rescuing device for a heavy wheeled vehicle. A base frame is mounted above a frame between two rear axle wheels at the tail of the dragging and rescuing vehicle through a saddle, an auxiliary winch is mounted on the base frame, a turnover oil cylinder is mounted on the base frame, a mast is slidably connected with the base frame, and the upper end of the mast is hinged to a telescopic rod of the turnover oil cylinder; the mast is controlled to move up and down and turn over along the base frame through stretching and retracting of the turning oil cylinder, the supporting arm is hinged to the lower end of the mast, a telescopic rod of the lifting oil cylinder is hinged to the supporting arm, turning over of the supporting arm is controlled through stretching and retracting of the lifting oil cylinder, a detachable parking shovel is installed at the front end of the supporting arm, and the main winch is installed on the portion, in front of the base frame, of the vehicle body. During dragging and rescuing operation, the mode of single-rope traction of the auxiliary winch, single-rope traction of the main winch or double-rope traction of the main winch and the auxiliary winch can be provided according to different conditions. The dragging and rescuing vehicle can be reliably supported, sufficient traction force can be provided, and safe dragging and rescuing operation can be carried out on heavy wheeled vehicles in complex environments such as silting, sand sinking and ditch falling.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a tow rescue device for heavy-duty wheeled vehicles. Background technique [0002] When a wheeled vehicle fails to run normally due to a malfunction or accident, in order to clear the road or send it to the factory for repair in time, it is usually necessary to use a tow truck to drag the faulty vehicle away from the roadway or return it to the repair shop. Currently, existing tow vehicles can only tow and rescue small and light wheeled vehicles. If the faulty vehicle is a heavy-duty vehicle, and the heavy-duty vehicle is in a complex environment such as silt, sand or ditch, the existing tow trucks often cannot reliably support tow rescue due to insufficient traction force and no supporting force. In the process of towing and rescuing, the towed vehicle is often overturned due to the heavy weight of the rescued vehicle, which poses a safety hazard to the towed vehicle and can...
