Description

Technical Field

[0001] The present application relates to the technical field of winches, and in particular to a winch with a braking function. Background Art

[0002] A winch uses a cable wound around a drum to reel in and out objects. It can be used alone in heavy lifting applications requiring high traction, or as a component in machinery for lifting, road construction, and mine hoisting. It is widely used due to its simple operation, large rope capacity, and easy relocation. When a winch is in use, if the cable is pulling a load upward or lowering a load, a sudden loss of power can cause the load to rapidly slide or fall under its own weight, creating a dangerous situation. The winch, under the influence of the cable and the load, can slip, causing it to rotate very quickly. Without a brake mechanism, the winch cannot be stopped immediately. Prolonged slippage can damage both the load and the winch. Summary of the Invention

[0003] In view of this, the present application proposes a winch with a braking function.

[0004] According to one aspect of the present application, there is provided a winch with a braking function, comprising: a bracket, a rotating drum and a brake assembly;

[0005] The bracket includes: two supporting plates arranged opposite to each other; the two ends of the rotating drum are rotatably arranged on the two supporting plates, and the rotating drum is suitable for winding the cable;

[0006] One end of the drum is fixedly connected to a brake disc with an annular structure, and the center of the brake disc is on the same straight line as the axis of the drum; the brake assembly is located on the side of the drum where the brake disc is located;

[0007] The brake assembly includes: a brake handle, a connecting rod, a rotating shaft, a toggle and a brake band; the brake band is located inside the inner ring of the brake disc, and one end of the brake band is fixedly connected to the support plate, and the other end of the brake band is movably connected to the toggle;

[0008] The brake handle and the connecting rod are both located on the side of the support plate away from the rotating drum, and the brake handle is movably connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to one end of the rotating shaft, and the body length direction of the rotating shaft is perpendicular to the plane where the support plate is located. The end of the rotating shaft away from the connecting rod passes through the support plate and is fixedly connected to the toggle member. The brake handle is suitable for driving the toggle member to rotate through the connecting rod and the rotating shaft, and the toggle member is suitable for driving the brake band to move in a direction toward or away from the inner wall of the brake disc.

[0009] In a possible implementation, mounting discs are provided at both ends of the rotating drum, and the brake disc is provided on a side of one of the mounting discs facing away from the rotating drum.

[0010] In a possible implementation, a limiting hole is provided at one end of the connecting rod connected to the rotating shaft, and a limiting block is provided at one end of the rotating shaft connected to the connecting rod. The limiting block matches the limiting hole and can be embedded in the limiting hole.

[0011] In a possible implementation, the main body of the toggle member is an elliptical cylindrical structure.

[0012] In a possible implementation, the rotating shaft is provided with an isolation tube; the isolation tube is sleeved on the outside of the rotating shaft and is located between the support plate and the rotating shaft.

[0013] In a possible implementation, the device further includes: a return spring;

[0014] One end of the return spring is connected to the toggle member, and the other end of the return spring is connected to the brake band, which is suitable for setting a preset distance between the brake band and the inner wall of the brake disc when the spring is in a free state.

[0015] In a possible implementation, one end of the brake handle is rotatably connected to the support plate, and the connecting rod is hinged to the middle portion of the brake handle.

[0016] In a possible implementation, it further includes: arc-shaped teeth; the arc-shaped teeth are fixedly arranged on the side of the support plate away from the rotating drum, and the brake handle is provided with a tongue, and the brake handle is detachably connected to the arc-shaped teeth through the tongue.

[0017] In a possible implementation, a cylinder shaft is fixed at the center of the two mounting plates away from the rotating cylinder; the cylinder shaft rotates through the bearing and the support plate.

[0018] Beneficial effects: The bracket is suitable for supporting and installing the rotating drum, ensuring that the rotating drum can rotate on the bracket, so that the rotating drum drives the cable to be lowered or reeled in; the brake assembly is suitable for reducing the rotating speed of the rotating drum during high-speed rotation of the rotating drum and finally braking the rotating drum to stop rotation. During the normal rotation of the drum, the brake belt is initially suspended in the inner ring of the brake disc. There is a certain distance between the brake belt and the inner ring of the brake disc and they will not directly contact each other. At this time, the brake belt will not interfere with the normal rotation of the drum, and the drum will maintain its rotating state. When the drum needs to brake, the brake handle is operated to rotate the toggle member, driving the brake belt to move toward the inner wall of the brake disc. When the brake belt contacts the inner wall of the brake disc, friction resistance is generated between the brake belt and the inner wall of the brake disc. Since the brake disc and the drum are fixedly connected, the speed of the drum can be reduced and the drum can be stopped under the action of friction. When the drum stops, the toggle member is rotated in the opposite direction, and the toggle member drives the brake belt to gradually move away from the inner wall of the brake disc, and finally the brake belt is reset to its initial position.

In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0043] Figure 1 A diagram showing the main structure of a winch with a braking function according to an embodiment of the present application; Figure 2The main structure diagram of the winch with a braking function according to an embodiment of the present application is shown; Figure 1 As shown, the winch with a braking function comprises: a bracket, a drum 100 and a brake assembly; the bracket comprises: two support plates 200 arranged opposite to each other; the two ends of the drum 100 are rotatably arranged on the two support plates 200, and the drum 100 is suitable for winding cables; one end of the drum 100 is fixedly connected to a brake disc 400 with an annular structure, and the center of the brake disc 400 is on the same straight line as the axis of the drum 100; the brake assembly is located on the side of the drum 100 where the brake disc 400 is provided; the brake assembly comprises: a brake handle 300, a connecting rod 500, a rotating shaft 510, a toggle member 700 and a brake band 600; the brake band 600 is located in the inner ring of the brake disc 400, and one end of the brake band 600 is connected to the support plate 20 0 is fixedly connected, and the other end of the brake band 600 is movably connected to the toggle piece 700; the brake handle 300 and the connecting rod 500 are located on the side of the support plate 200 away from the rotating drum 100, and the brake handle 300 is movably connected to one end of the connecting rod 500, and the other end of the connecting rod 500 is fixedly connected to one end of the rotating shaft 510, and the body length direction of the rotating shaft 510 is perpendicular to the plane where the support plate 200 is located. The end of the rotating shaft 510 away from the connecting rod 500 passes through the support plate 200 and is fixedly connected to the toggle piece 700. The brake handle 300 is suitable for driving the toggle piece 700 to rotate through the connecting rod 500 and the rotating shaft 510, and the toggle piece 700 is suitable for driving the brake band 600 to move in a direction toward or away from the inner wall of the brake disc 400.

[0044] Here, it should be noted that the bracket is suitable for supporting and installing the drum 100, ensuring that the drum 100 can rotate on the bracket, so that the drum 100 can drive the cable to be lowered or reeled; the brake assembly is suitable for reducing the rotation speed of the drum 100 during the high-speed rotation of the drum 100 and finally braking the drum 100 to stop rotating. Furthermore, the bracket includes two support plates 200. The arrangement of the two support plates 200 can improve the installation stability of the overall equipment, can withstand greater pressure, and effectively support both ends of the drum 100. Further, as Figure 7As shown, the brake handle 300 is suitable for driving the connecting rod 500 to rotate, and the connecting rod 500 is suitable for driving the rotating shaft 510 to rotate. When the rotating shaft 510 rotates, it can drive the toggle member 700 at one end of the rotating shaft 510 to rotate. Since the toggle member 700 is connected to the brake band 600, when the toggle member 700 rotates, it can drive the brake band 600 to move. The brake band 600 rotates slightly with one end of the brake band 600 connected to the support plate 200 as the center, thereby realizing the movement of the brake band 600 toward or away from the inner wall of the brake disc 400. It should be noted that during the normal rotation of the drum 100, the brake band 600 is initially suspended within the inner ring of the brake disc 400. There is a certain distance between the brake band 600 and the inner ring of the brake disc 400 so that they do not directly contact each other. At this time, the brake band 600 will not interfere with the normal rotation of the drum 100, and the drum 100 will maintain its rotation state. When the drum 100 needs to brake, the toggle member 700 rotates, driving the brake band 600 to move toward the inner wall of the brake disc 400. When the brake band 600 contacts the inner wall of the brake disc 400, frictional resistance is generated between the brake band 600 and the inner wall of the brake disc 400. Since the brake disc 400 is fixedly connected to the drum 100, the friction force can reduce the speed of the drum 100 and ultimately stop the drum 100. When the drum 100 stops, the toggle member 700 rotates in the opposite direction, driving the brake band 600 to gradually move away from the inner wall of the brake disc 400, and finally returning the brake band 600 to its initial position. The overall structure of this application is compact. While having the function of lifting and lowering heavy objects, it can also achieve the ability to brake the winch at any time, preventing the winch from slipping for a long time, extending the service life of the winch, and preventing damage to the load and cable caused by the heavy object falling to the ground at high speed.

[0045] In one possible implementation, Figure 5 As shown, mounting plates 110 are provided at both ends of the drum 100, and the brake disc 400 is mounted on the side of one of the mounting plates 110 facing away from the drum 100.

[0046] In one possible implementation, Figure 5 As shown, a drum shaft 120 is fixedly provided at the center of the two mounting plates 110 away from the drum 100. Figure 16 As shown, the two mounting plates 110 are provided with bolt holes 111, as shown in FIG. Figure 8As shown, bolt holes 121 are provided at one end of the two cylindrical shafts 120; the bolt holes 111 and the bolt holes 121 are aligned one by one, and the mounting plate 110 and the cylindrical shafts 120 are fixedly connected by bolts. The cylindrical shafts 120 are rotatably connected to the support plate 200 via bearings 121. The two cylindrical shafts 120 are respectively inserted into the mounting grooves 201 of the support plates 200 on both sides. Bearings 121 are sleeved on the outside of the cylindrical shafts 120. The bearings 121 are set in the mounting grooves 201 of the support plates 200 and are fixedly connected to the support plates 200 via bearing seats 122. Under the action of the bearings 121, the cylindrical shafts 120 can rotate smoothly, thereby realizing a rotatable connection between the rotating drum 100 and the bracket.

[0047] Further, such as Figure 2 As shown, the bearing 121 is provided with a bearing seat 122, and the bearing seat 122 is provided with two or more bolt holes; Figure 17 As shown, more than two bolt holes 202 are provided around the mounting groove 201 of the support plate 200 ; the bearing seat 122 and the support plate 200 can be fixed by bolt connection, thereby improving the installation stability of the bearing 121 .

[0048] It should be noted that the cylindrical shaft 120 can be connected to the output end of the motor, and the motor directly drives the cylindrical shaft 120 to rotate, and the cylindrical shaft 120 drives the rotating drum 100 to rotate, so that the rotating drum 100 can retract and release the cable.

[0049] In one possible implementation, Figure 7 As shown, the main body of the brake disc 400 is annular in structure, a plurality of bolt holes 420 are provided on the brake disc 400, and a plurality of bolt holes 112 are correspondingly provided on the mounting plate 110.

[0051] Further, such as Figure 17 As shown, the support plate 200 is provided with a bolt hole 204 , and the bolt hole 204 is arranged opposite to the connecting member 610 , and the support plate 200 and the connecting member 610 can be fixedly connected by bolt connection.

[0052] In a possible implementation, the brake band 600 uses an asbestos brake pad.

[0053] In a possible implementation, the main body of the toggle member 700 is an elliptical cylindrical structure. Figure 11 As shown, the brake band 600 is movably connected to the toggle member 700. Further, as shown in FIG. Figure 2 As shown, a movable groove 710 is formed on the side wall of the toggle 700, and a protrusion 630 is formed on the end of the brake band 600 connected to the toggle 700; the protrusion 630 extends into the movable groove 710. When the toggle 700 rotates clockwise, the lower end of the toggle 700 rotates leftward and presses the brake band 600 to the left, so that the brake band 600 gradually approaches the inner ring of the brake disc 400 and finally contacts each other to form a Figure 8 After the brake is completed, the reverse rotation of the toggle member 700, the lower end of the toggle member 700 is rotated to the right to release the brake band 600, the brake band 600 leaves the inner ring of the brake disc 400 to form Figure 7 The status shown.

[0054] In one possible implementation, Figure 6 and 10 As shown, the apparatus further includes a return spring 800; one end of the return spring 800 is connected to the toggle member 700, and the other end of the return spring 800 is connected to the brake band 600. This spring is adapted to maintain a predetermined distance between the brake band 600 and the inner sidewall of the brake disc 400 when the spring is in a free state. It should be noted that the provision of the return spring 800 improves the rapid resetting of the toggle member 700 and the rapid separation of the brake band 600 from the brake disc 400, effectively preventing the brake band 600 from being delayed in resetting and causing difficulty in rotating the drum 100.

[0055] Further, such as Figure 12 As shown, the brake band is provided with a spring connecting hole 640; the toggle block 700 is provided with a spring connecting hole 720; hooks are provided at both ends of the return spring 800, and the hooks at both ends of the spring are respectively hooked with the spring connecting hole 640 and the spring connecting hole 720, thereby realizing the installation of the return spring 800.
