Description

Technical Field

[0001] The invention belongs to the technical field of winches and relates to a manual lifting device for a winch. Background Art

[0002] Manual winches are very useful in a variety of situations. They are mainly used to lift, pull or position heavy objects. On construction sites, manual winches are often used to lift building materials, tools and other equipment to the required height. In industrial environments, they are used to move heavy machinery, equipment parts or other heavy objects. Due to their portability, they are also widely used in many other fields.

[0003] The existing manual hoisting device of the winch simply relies on manual rotation to lift the objects. Therefore, during long-term use, the staff will have to manually rotate the objects too many times. In addition, the existing manual hoisting device of the winch only relies on manual rotation, which will lead to a high work intensity. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a manual hoisting device for a winch, which solves the problem that the existing manual hoisting device for a winch simply relies on manual rotation to lift objects, thus resulting in high operating intensity during long-term use.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The cam is connected with the gear train of the gear shifting device and the gear train is connected with the gear train of the gear shifting device and the gear train is connected with the gear train of the gear shifting device.

[0007] Preferably, the tail end of the rocker is rotatably connected to a handle, the outer wall of the side plate is fixedly connected to a reinforcement plate, and the bottom of the reinforcement plate is fixedly connected to the top surface of the bottom plate.

[0008] Preferably, the fixing assembly includes a pull rod, an insertion rod and a spring; the bottom of the pull rod is rotatably connected to the middle part of one side of the outer wall of the cover shell, the middle and upper part of the pull rod is rotatably connected to one end of the insertion rod, the middle part of the insertion rod is arranged on the upper part of one side of the cover shell, the other end of the insertion rod is arranged on one side of the main gear, one side of the spring is fixedly connected to the middle part of the pull rod, and the other side of the spring is fixedly connected to the middle part of one side of the outer wall of the cover shell.

[0009] Preferably, a plurality of slots are provided on the outer middle portion of one side of the main gear, and one end of the insertion rod is located inside one of the slots.

[0010] Preferably, an ear plate is fixedly connected to the middle of one side of the outer wall of the cover shell, a support rod is fixedly connected to the bottom of the pull rod, and the support rod is rotatably connected to the middle of the ear plate.

[0011] Preferably, a first connecting seat is fixedly connected to the middle upper portion of one side of the pull rod, a clamping rod is fixedly connected to one end of the insertion rod, and the clamping rod is rotatably connected to the middle portion of the first connecting seat.

[0012] Preferably, a mounting hole is provided at the top of one side of the outer wall of the housing, and the middle portion of the insertion rod is located inside the mounting hole.

[0013] Preferably, a limiting hole is provided in the middle of the insertion rod, and a limiting rod is fixedly connected to the interior of the mounting hole, and the limiting rod is located inside the limiting hole.

[0014] Preferably, the width of the mounting hole is greater than the width of the insertion rod.

[0015] Working principle: When in use, the bottom plate serves as the foundation of the entire device, bearing the weight of each component, and the side plate is fixedly connected to the top surface of the bottom plate. One side of the winch is rotatably connected to the side plate. When the steel cable needs to be reeled in, first pull the top of the pull rod to move the insertion rod away from the main gear, and then rotate the handle to drive the rocker to rotate, and the rocker can drive the second gear to rotate, and the second gear can drive the first gear to rotate. Therefore, under the rotation of the first gear, the main gear can drive the winch to rotate, thereby realizing the retraction and release of the steel cable, and when the rocker is used to drive the winch to rotate, the gear ratio of the main gear, the first gear and the second gear can be used to make the rocker rotate manually. When the winch is rotated, the purpose of labor saving is achieved, and when the winch is rotated, the power-assist motor can be started, and the power-assist motor can be used to drive the third gear to rotate, and the third gear can be used to drive the fourth gear to rotate, so that the first gear can be used to assist the rotation of the rocker, thereby achieving the effect of labor saving, and a fixing component is provided in the middle of the outer wall of the cover shell, and the fixing component mainly includes a pull rod, an insertion rod and a spring. Therefore, when the winch needs to be fixed, the pull rod is loosened. At this time, the pull rod can be pulled back by the spring, so that the insertion rod is close to the main gear and inserted into the inside of the slot. At this time, the insertion rod can be used to clamp the main gear, thereby preventing the winch from rotating and causing the steel cable to be released, thereby improving the safety of use.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention can drive the winch to rotate by rotating the rocker. At this time, the steel cable can be retracted to lift the equipment. The gear ratio between the main gear, the first gear and the gear can facilitate manual rotation by the staff. At the same time, the third gear can be driven to rotate by driving the power-assisting motor, thereby realizing auxiliary rotation of the rocker, thereby avoiding the increase of work intensity caused by too many manual rotations.

[0018] 2. The present invention can make the pull rod close to the cover shell through the elastic force of the spring. At this time, the pull rod can drive the insertion rod to approach the main gear. When one end of the insertion rod enters the slot on one side of the main gear, the insertion rod can be used to lock the main gear, thereby avoiding the phenomenon that the winch rotates and causes the steel cable to be released, thereby improving the practicality of the device.
