Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a multifunctional winch fixing device and a winch. Background Art

[0002] A winch is a device that can be used for traction. It is mainly used for self-rescue and rescue of vehicles in harsh environments. When a vehicle is stuck in mud or rugged terrain and it is difficult for all four wheels to land, the winch can use other objects as a fulcrum to tow the vehicle out of danger. The winch can also be used to pull or drag large obstacles such as trees. The existing electric winch is mainly composed of a motor body, a transmission shaft, a reduction gearbox, a winch drum and other structures. The reduction gearbox connects the power between the motor body and the winch drum, so that the wire rope wound on the winch drum can generate a large traction force to achieve the winch traction function.

[0003] However, the winches currently in use can generally only be used in conjunction with a rescue tripod for underground or tunnel rescue. Their usage scenarios are limited, and during use, multiple protection personnel are often required to monitor the safety of the winch. Utility Model Content

[0006] A multifunctional winch fixing device of the present application is provided with a screw transmission device and a clamping part on the winch base. The opening and closing degree of the clamping part can be controlled by the extension and retraction of the screw transmission device, so that the winch can be fixed on different objects. At the same time, the L-shaped clamping plate can be inserted into a gap such as a wheel hub, thereby improving the stability of the winch and solving the problem in the prior art that when the winch is used in conjunction with a tripod, the usage scenario is single and multiple safety personnel need to be equipped.

The rotation of the sleeve drives the screw connecting the fixed part and the telescopic part to rotate, thereby driving the telescopic part to move forward and backward in the cavity of the fixed part, thereby completing the telescopic movement of the telescopic part.

[0008] As an improvement of the above-mentioned mounting part of the present application, the mounting part includes: a front plate, a support frame, a support frame connecting piece and a belly plate boss. The front plate and the support frame are sleeve-mounted on the outer surface of the fixed part, and the front plate and the support frame are positioned by the limiting boss on the fixed part to prevent the mounting part from detaching from the surface of the fixed part. Two support frame connecting pieces are symmetrically welded to the lower part of the support frame, and a certain gap is left between the two support frame connecting pieces.

[0009] Furthermore, the front plate is installed on the front cylindrical surface of the fixing part, and the support frame is installed on the remaining three cylindrical surfaces of the fixing part in a sleeve-like manner.

[0010] Furthermore, the upper end surface of the front plate has a trapezoidal boss integrally formed therewith, a connecting end ring is welded in front of the trapezoidal boss, and a front plate connecting piece is welded on the lower end surface of the front plate.

[0011] Furthermore, a groove is formed on the trapezoidal boss.

[0012] As an improvement of the support frame of the present application, the support frame includes an upper belly plate, a bottom plate, and a back plate. The upper belly plate and the bottom plate are respectively tightly fitted with the upper cylindrical surface and the lower cylindrical surface of the fixed part, and the back plate is tightly fitted with the rear cylindrical surface of the fixed part. The support frame connecting piece is welded and installed on the bottom plate and connected to the front plate connecting piece by a pin, and the belly plate boss is welded and installed on the upper belly plate and keeps in fit with the trapezoidal boss.

[0013] Furthermore, a groove is formed on the web boss, and coaxial through holes are formed on the groove walls on both sides of the groove.

[0014] As an improvement of the clamping part of the present application, the clamping part includes: an L-shaped clamping plate installed on the lower cylindrical surface of the telescopic part and the lower cylindrical surface of the fixed part, and a reinforcing plate connecting the left end surface of the lower cylindrical surface of the telescopic part, the right end surface of the lower cylindrical surface of the fixed part and the L-shaped clamping plate, wherein the two L-shaped clamping plates are symmetrically distributed, their long sides are vertically welded on the end surfaces, and the short sides are horizontally arranged, and the short sides of the two symmetrical L-shaped clamping plates are in the same horizontal plane.

[0015] As an improvement of the above-mentioned connecting part of the present application, the connecting part includes: a clamping screw, a fixing pin and a handle, the clamping screw is arranged in the grooves of the web boss and the trapezoidal boss, the end of the clamping screw is provided with a through hole coaxial with the web boss, one end of the clamping screw is fixed by the fixing pin through the through hole, the other end of the clamping screw passes through the connecting end ring, and the handle is screwed and connected to the clamping screw.

[0016] Based on the same concept of the above-mentioned winch fixing device, the present application also provides a winch, which includes any one of the winch fixing devices in the above-mentioned solutions.

[0017] The beneficial effects of this application are:

[0018] 1. A multifunctional winch fixing device of the present application adds a screw transmission device with a clamping function to the base of the winch, and connects the screw transmission device and the winch with a fixing part. The opening and closing degree of the clamping part can be adjusted by the extension and retraction of the screw transmission device, so that the winch can be fixed on different objects, which solves the problem of the single usage scenario caused by the tripod used to match the winch in the prior art.

[0019] 2. The clamping part of the present application is composed of an L-shaped clamping plate and a reinforcing plate. The short side of the L-shaped clamping plate can extend into the wheel hub gap of various vehicles commonly used in emergency rescue. The clamping of the clamping part is controlled by a screw transmission device, which greatly improves the stability of the winch during use. At this time, only one safety personnel is needed to inspect the winch, which greatly reduces the labor cost. BRIEF DESCRIPTION OF THE DRAWINGS
