[0001] The invention relates to a multi-angle winch system and belongs to the technical field of emergency rescue. Background Art
[0002] At present, a traction winch and a truck crane are installed on some rescue vehicles, such as emergency fire trucks. The traction winch is used to drag objects for self-rescue or rescue, and the truck crane is used to remove or transfer objects.
[0003] Once the existing traction winch is installed in a fixed position on the vehicle, the towing operation can only be carried out along the rope output direction of the winch. When multiple rescue points are located in different directions, the vehicle angle needs to be adjusted so that the rope output direction of the winch is aligned with the rescue point, which greatly limits the operating range of the rescue vehicle. Summary of the invention
[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a multi-angle winch system, which can solve the problem that traditional winches can only operate along the rope output direction. The winch system has a large operating range and can freely switch between multiple directions and multiple angles, which is more conducive to the implementation of self-rescue or towing rescue.
[0005] In order to achieve the above-mentioned object, the present invention provides a multi-angle winch system, including a winch mechanism, wherein the winch mechanism includes a winch, a support rod 1, a support rod 2, a guide turning wheel 1 and a connecting and fixing frame, wherein the connecting and fixing frame is fixed on a vehicle body, and includes a horizontal mounting surface with an open end, wherein the winch is fixed on the mounting surface, and the end where the rope outlet is located faces the direction where the open end of the mounting surface is located;

[0007] A guide and direction-changing wheel is arranged at the hinge point. The guide and direction-changing wheel is rotatably connected to the hinge shaft at the hinge point, and the center of the wheel is coaxially arranged with the hinge shaft.
[0008] Furthermore, it also includes a bracket mechanism, which includes a top seat, a second guide and direction-changing wheel, a plurality of longitudinal support rods and a transverse connecting rod. The upper ends of the plurality of longitudinal support rods are hinged to the outer circumference of the lower end surface of the top seat at equal intervals, the lower end of each longitudinal support rod is hinged to a foot, and the lower parts of adjacent longitudinal support rods are hingedly connected by a transverse connecting rod; the second guide and direction-changing wheel is rotatably connected to the middle part of the lower end surface of the top seat.
[0009] Furthermore, the support rod 2 includes a sleeve section 1 and a rod body section 1 slidably sleeved therein, the sleeve section 1 has a connecting hole 1 at one end close to the rod body section 1, a plurality of connecting holes 2 are provided on the rod body section 1 corresponding to the connecting hole 1, and the connecting holes 1 and the connecting holes 2 are connected by a pin shaft 1.
[0010] Furthermore, the longitudinal support rod includes a sleeve section 2 and a rod body section 2 slidably sleeved therein, the sleeve section 2 is provided with a connecting through hole 3 at one end close to the rod body section 2, and a plurality of connecting through holes 4 are provided on the rod body section 2 corresponding to the connecting through hole 3, and the connecting through holes 3 and 4 are connected by a pin 2; the transverse connecting rod is a two-section type hingedly connected, the middle part of each transverse connecting rod is hingedly connected by a pin 3, and the two ends are hingedly connected to the longitudinal support rod on its side by pins 4 and 5 respectively.

When in use, the rope is extended from the winch, wound around the guide turning wheel and connected to the rescue object. The angle rotation range of the hinge between the support rod one, the support rod two and the connecting fixed frame can meet the multi-angle and multi-directional operation of the rope to a certain extent; the support rod two is set as a retractable sleeve structure to further increase the angle range of the rope operation; by adding a bracket mechanism, lifting and towing operations across obstacles can be carried out without using a truck crane, thereby overcoming the defects that the lifting capacity of the existing truck crane is greatly affected by the distance, the truck crane itself has a large weight and volume, and the installation of the truck crane together with the traction winch occupies a large vehicle carrying space, which is more conducive to the implementation of self-rescue or towing.

[0024] In order to overcome the defects of existing truck cranes that the lifting capacity is greatly affected by the distance, the truck crane itself is heavy and large in size, and it takes up a large vehicle carrying space when installed together with the traction winch, it is possible to carry out lifting and towing operations across obstacles without using the truck crane, such as Figure 5As shown, the system also includes a support mechanism 9, which includes a top seat 10, a guide and direction-changing wheel 11, a plurality of longitudinal support rods 12 and a transverse connecting rod 13.

According to the on-site conditions, this system can perform lateral towing operations, forward towing operations, lifting operations and towing operations across obstacles. These four operation processes are described in detail below.
[0028] 1. Lateral dragging operation
[0029] like Figure 3 As shown, when the rescued object 28 is not in the winch rope-out direction A, there is an angle α between the traction direction B of the winch rope 29 and the winch rope-out direction A, the winch mechanism is adjusted to the unfolded state, the winch rope 29 comes out of the winch 1, bypasses the guide changing wheel 4 and connects with the rescued object 28; the winch cable drum of the winch 1 rotates to recover the winch rope 29, and the winch rope 29 bypasses the guide changing wheel 4 and changes direction to drag the rescued object 28 in the opposite direction of direction B to perform a lateral towing operation.
[0030] 2. Forward dragging operation
[0031] like Figure 4 As shown, when the rescued object 28 is in the direction A of the winch's rope output, that is, when the angle α is 0° or within the range that the winch 1 can withstand, the winch mechanism is adjusted to the recovery state, the winch rope 29 is connected to the rescued object 28, and the winch drum of the winch 1 rotates to recover the winch rope 29, dragging the rescued object 28 along the recovery direction of the winch rope 29 to perform a forward towing operation.
[0032] 3. Lifting Operation
[0033] like Figure 6 As shown, the winch mechanism is adjusted to the unfolded state, and the bracket mechanism is unfolded and placed above the rescued object 28. The winch rope 29 comes out of the winch 1, bypasses the guide changing wheel 1 4 and the guide changing wheel 2 11, and is connected to the rescued object 28. There is an angle α between the traction direction B of the winch rope 29 and the winch rope output direction A. The winch cable drum of the winch 1 rotates to recycle the winch rope 29. The winch rope 29 bypasses the changing wheel 4 and the guide changing wheel 2 11 and changes direction, and then drags the rescued object 28 upward to perform the lifting operation.
[0034] 4. Dragging across obstacles
[0035] like Figure 7 As shown, the winch mechanism is adjusted to the unfolded state, and the bracket mechanism is unfolded and placed next to the rescued object 28. The winch rope 29 comes out of the winch 1, bypasses the guide turning wheel 1 4 and the guide turning wheel 2 11, crosses the obstacle 30, and then connects with the rescued object 28. There is an angle α between the traction direction B of the winch rope 29 and the winch rope output direction A. The winch cable drum of the winch 1 rotates to recycle the winch rope 29. The winch rope 29 bypasses the guide turning wheel 1 4 and the guide turning wheel 2 11 and changes direction, then drags the rescued object 28 to move, and performs the towing operation across the obstacle 30.
