Description

Technical Field

[0001] This utility model relates to power construction equipment, and in particular to a winch. Background Technology

[0002] A winch (also known as a motorized winch, traction winch, or cable winch) is a mobile mechanical device driven by a diesel engine, gasoline engine, or electric motor. It uses gears or a hydraulic system to reduce speed and increase torque, and then winds a steel wire rope / traction rope onto a drum to provide strong linear traction. In power engineering, cables are heavy and difficult to drag manually; this is where winches come in. Existing winches have a relatively simple structure, mainly including a winch, traction rope, reducer, and diesel (gasoline) engine. During construction, the engine drives the winch connected to the reducer, thus completing the cable traction action. It's important to note that during traction, the winch is subjected to a large traction force and is easily pulled by the cable. Therefore, stones are often placed on the winch's chassis during construction to increase stability. However, this method of piling stones on the winch is not safe because the stones are mostly taken on-site and have irregular shapes. Their placement on the winch is unstable. When the winch is moved by the reverse force from the cable, the unstable stones are very likely to fall off the winch, causing a series of accidents. Utility Model Content

[0003] The purpose of this utility model is to provide a winch to solve the problem of poor stability of existing winches during cable pulling.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A winch, comprising

[0006] The chassis is L-shaped.

[0007] The main body of the winch has an L-shaped structure and is appropriately arranged on the chassis;

[0008] A counterweight placement frame is placed in the L-shaped gap of the chassis to allow counterweights to be placed during electrical work.

[0009] Preferably, the counterweight placement frame includes a fixed mesh plate fixedly connected to the chassis. The fixed mesh plate covers the back of the winch of the winch body. Two folded mesh plates are symmetrically arranged on both sides of the fixed mesh plate. One side of the folded mesh plate is hinged to the fixed mesh plate, and the free end of the other side is hinged to a movable mesh plate. A limiting plate is provided at the bottom of the movable mesh plate. When the folded mesh plate is opened, the fixed mesh plate, the movable mesh plate, and the two folded mesh plates form a rectangular frame. A bottom plate is also hinged to the chassis. When the bottom plate is folded down, the free end of the bottom plate rests on the upper surface of the limiting plate.

[0010] Preferably, a support arm is provided on one side of the chassis, the support arm extends rearward to below the limiting plate, one end of the limiting plate is mounted on the upper surface of the chassis, and the other end is mounted on the support arm.

[0011] Preferably, the limiting plate has first pin holes at both ends, and the chassis and support arm have second pin holes. After the counterweight placement frame is unfolded, a locking pin passes through the first pin hole and is inserted into the second pin hole.

[0012] Preferably, the chassis is further provided with a third pin hole. After the counterweight placement frame is folded, the locking pin passes through the first pin hole and is inserted into the third pin hole.

[0013] Preferably, the upper edge of the fixing mesh plate is provided with binding straps.

[0014] Preferably, a plurality of anti-reverse pins are evenly distributed on the lower surface of the free end of the base plate, and a plurality of fourth pin holes are provided on the limiting plate. When the base plate is laid horizontally, the anti-reverse pins are inserted into the fourth pin holes.

[0015] Preferably, the support arm is hinged to the chassis, and the support arm has two fifth pin holes, in which a U-shaped pin is inserted. The chassis has a sixth pin hole on the side near the support arm. When the support arm is flipped back to fit against the chassis, one end of the U-shaped pin is inserted into the fifth pin hole and the other end is inserted into the sixth pin hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This solution involves setting a counterweight placement frame on the chassis. The counterweights used to increase stability during the operation of the winch can be placed in the counterweight placement frame, which can effectively prevent the counterweights from falling off the chassis of the angle grinder during operation.

[0018] 2. The counterweight in this design prevents the basket from having a foldable storage structure, making it convenient for subsequent handling and storage.

[0019] 3. By setting up support arms, the stability of the counterweight placement frame after the heavy object is placed in is ensured, as well as its integrity with the winch. Attached Figure Description

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1-3 The diagram shows a winch, including a chassis 1 with an L-shaped structure. A winch body 2, used for electrical work (cable pulling), is mounted on the chassis. The winch body 2 mainly consists of a winch, coupling, reducer, and power components (diesel engine, gasoline engine, electric motor). These components are adapted to the L-shaped chassis, and their connection method is also L-shaped. Therefore, there is an empty section behind the winch. It should be noted that... Figure 1 As shown, a counterweight placement block 3 is installed in the empty space of the chassis. This counterweight placement box can hold loose counterweight blocks to increase the overall weight of the winch during electrical work, preventing the winch from moving due to the reaction force when dragging cables. It is important to note that because of the presence of the counterweight placement box, even if the winch moves due to the reaction force of the cable during electrical work, the counterweight blocks will not fall off and cause subsequent adverse reactions.

[0028] It is important to note that in this design, the counterweight placement frame 3 is foldable for easy handling and storage, minimizing space requirements. Specifically, the counterweight placement frame includes a fixed mesh plate 31 fixedly connected to the chassis 1, located behind the winch of the winch body. Two folding mesh plates 32 are symmetrically arranged on both sides of the fixed mesh plate 31. These folding mesh plates can be folded into a screen-like structure and are hinged to the fixed mesh plate. A movable mesh plate 33 is hinged to the end of each folding mesh plate that is not connected to the fixed mesh plate. Figure 1 As shown, when the folding mesh panel is unfolded, the fixed mesh panel, the movable mesh panel, and the folding mesh panel form a rectangular frame for placing the counterweight. When the folding mesh panel is folded down, the movable mesh panel and the fixed mesh panel overlap, reducing the space occupied by the counterweight placement box.

[0029] It is also important to know that in this design, a limiting plate 35 is connected to the lower edge of the movable mesh plate. Simultaneously, a base plate 34 is hinged to the chassis. This base plate is located within the frame formed by the fixed mesh plate, the movable mesh plate, and the folding mesh plate. When the base plate is folded down, its movable edge presses against the upper surface of the limiting plate 35 to ensure that the counterweight placed in the counterweight placement frame 3 can increase the stability of the entire winch.

[0030] Furthermore, it should be noted that if the counterweight placement frame in this solution only transmits the force of the counterweight through a fixed mesh plate, its reliability is somewhat lacking. Therefore, this solution also provides a support arm 11 on the side of the chassis 1. This support arm extends rearward to below the limiting plate 35, so that during operation, one end of the limiting plate is assumed to be on the upper surface of the chassis 1, and the other end is supported on the support arm.

[0031] It should also be noted that, to improve the stability of the counterweight placement frame shape during operation, this design includes a first pin hole 351 at each end of the limiting plate. Simultaneously, second pin holes 111 are provided on the chassis and support arm. During electrical work, after unfolding the counterweight placement frame, the first and second pin holes are aligned coaxially. At this point, a locking pin 36 can be inserted into the second pin hole 111 after passing through the first pin hole to ensure that the limiting plate does not move relative to the counterweight placement frame, thus preventing any change in its shape.

[0032] It should also be noted that in this solution, a third pin hole 112 is provided near the winch on the chassis 1. When the counterweight block 3 is folded and stored, a first pin hole on the limiting plate is coaxially opposite to the third pin hole. At this time, the locking pin can be passed through the first pin hole and the third pin hole to fix the shape of the folded counterweight block placement frame by locking the limiting plate.

[0033] Furthermore, this solution can also use binding straps 37 to bind the folded fixed mesh panel together with the movable mesh panel. Specifically, at least one binding strap 37 is provided along the upper edge of the fixed mesh panel.

[0034] In addition, to ensure the stability of the base plate during electrical operations, several anti-reverse pins 341 are evenly distributed on the lower surface of the base plate at both ends. Meanwhile, several fourth pin holes 352 are provided on the limiting plate 35. When the base plate is tilted down, the anti-reverse pins are inserted into the fourth pin holes to ensure that the base plate will not slip off the limiting plate due to heavy pressure.

[0035] It is also important to know that, to reduce the impact of the support arm during storage, in this design, the support arm 11 and the chassis 1 are connected by a rotatable hinge structure. When the counterweight anti-framing frame is folded and stored, the support arm can be flipped to fit against the edge of the chassis. To prevent the support arm from swinging freely after flipping, two fifth pin holes 113 are provided on the support arm 11, and a U-shaped pin 12 is inserted into each of these five fifth pin holes 113. At the same time, a sixth pin hole 114 is also provided on the chassis 1. When the support arm rotates to fit against the chassis 1, the U-shaped pin is pulled out, so that one end of the U-shaped pin is inserted into the fifth pin hole and the other end is inserted into the sixth pin hole.

[0036] This solution prevents the counterweight, which is used to increase the stability of the winch during power operations, from falling off the winch by setting up a counterweight anti-fall frame, thereby ensuring the safety of dragging cables during power operations.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
