Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically a bidirectional self-locking structure based on a winch. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects; it is also called a winch. Winches can lift vertically and pull horizontally or at an angle. Winches are divided into three types: manual winches, electric winches, and hydraulic winches. Currently, electric winches are the most common. They can be used independently or as components in lifting, road construction, and mine hoisting machinery. However, the existing self-locking structure of winches still encounters some problems in actual use.

[0003] For example, application number CN202220350153.9 discloses a locking and protective structure for a winch, including a winch body. The side wall of the winding drum of the winch body is provided with a locking and protective structure. The locking and protective structure locks and protects the winding shaft of the winding drum. The locking and protective structure is connected to an automatic unlocking structure and a manual unlocking structure, which has the characteristic of reducing damage to the motor. Existing winch self-locking structures can often only perform locking operations during the descent process and cannot perform locking operations during the ascending state, resulting in significant limitations in use and making it unfavorable.

[0004] To address the aforementioned problems, a bidirectional self-locking structure based on a winch is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional self-locking structure based on a winch. By using this device, the problem of existing winch self-locking structures being unable to perform locking operations during the descent phase and thus limiting their use is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional self-locking structure based on a winch, comprising a mounting platform and a support frame fixedly connected to the top of the mounting platform, wherein two sets of support frames are provided, and a winding chamber is fixedly connected between the two sets of support frames. A winding roller is rotatably connected inside the winding chamber. A locking structure is provided inside both sets of support frames, and the locking structure locks the winding roller. The locking structure includes a spring rod fixedly connected inside one set of support frames, and a drive motor fixedly connected to one side of the other set of support frames. A pulley is fixedly connected to the output end of the drive motor.

[0007] Preferably, an electromagnet is fixedly connected inside the support frame, a locking block is fixedly connected to one end of the spring rod, and a ratchet is rotatably connected inside the support frame.

[0008] The above-described structure design, through the setting of the support frame, allows related components to be connected to the support frame, thereby improving the space utilization of the device.

[0009] Preferably, the ratchet is fixedly connected to the take-up roller, and the other set of support frames is rotatably connected to the pulley. A belt is fitted on the outer side of the pulley and the pulley, and the pulley is fixedly connected to the take-up roller.

[0010] By adopting the above-described structure, the transmission direction of the drive motor is changed through the setting of pulley one and pulley two, thus advancing the workflow.

[0011] Preferably, the second pulley is fixedly connected to the take-up roller, and a second ratchet is fixedly connected to one side of the second pulley. An electromagnet is also fixedly connected inside the other set of support frames. Both the second electromagnet and the first electromagnet are fixedly connected to the drive motor.

[0012] The above-described structure, through the arrangement of ratchet two and ratchet one, enables bidirectional self-locking of the take-up roller during the use of the overall structure.

[0013] Preferably, another set of the support frames also has a magnetic suction plate slidably connected inside. The magnetic suction plate is magnetically engaged with an electromagnet. A spring rod is fixedly connected to one side of the magnetic suction plate, and one end of the spring rod is fixedly connected to the inside of the other set of the support frames.

[0014] The above-described structure, with the addition of spring rod two, enables the magnetic plate to automatically reset, thus improving its usability.

[0015] Preferably, a connecting rod is fixedly connected to one side of the magnetic suction plate, a trapezoidal block is slidably connected to the top of the connecting rod, a second locking block is fixedly connected to the top of the trapezoidal block, the second locking block matches the second ratchet, and an installation chamber is fixedly connected to one side of another set of support frames.

[0016] The above-described structure, with the installation chamber, allows the magnetic plate to move along the connecting shaft during its movement, thus improving work efficiency.

[0017] Preferably, a connecting shaft is rotatably connected inside the mounting chamber, the connecting shaft is fixedly connected to a pulley, a sliding disc is slidably connected to one end of the connecting shaft, a friction disc is also fixedly connected inside the mounting chamber, and a fixing ring is fixedly connected to one side of the magnetic suction plate, the fixing ring matching the sliding disc.

[0018] The above-described structure, through the setting of the fixing ring and the sliding disc, achieves multiple fixing effects on the take-up roller.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application achieves bidirectional self-locking of the winding roller during overall structure use by setting ratchet one, ratchet two, support frame and electromagnet one, which improves the use effect and solves the problem that the existing winch self-locking structure can only lock during the descent process and cannot lock during the ascent, resulting in great limitations and inconvenience in use.

[0021] 2. This application achieves multiple fixing effects on the winding roller through the setting of sliding disc, pulley 1, connecting shaft and friction disc, which further improves the safety factor and solves the problem that the locking structure of the existing winch self-locking structure is mostly simple and cannot quickly brake the winding roller, resulting in the inability to adapt to rapid stop during use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-4 A bidirectional self-locking structure based on a winch includes a mounting platform 1 and a support frame 11 fixedly connected to the top of the mounting platform 1. The support frame 11 is provided in two sets, and a winding chamber 2 is fixedly connected between the two sets of support frames 11. A winding roller 21 is rotatably connected inside the winding chamber 2. A locking structure is provided inside both sets of support frames 11. The locking structure locks the winding roller 21. The locking structure includes a spring rod 111 fixedly connected inside one set of support frames 11, and a drive motor 12 fixedly connected to one side of the other set of support frames 11. A pulley 121 is fixedly connected to the output end of the drive motor 12.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1:

[0034] To address the limitation of existing winch self-locking structures, which typically only lock during descent and not during ascent, resulting in significant operational constraints, this embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, an electromagnet 112 is fixedly connected inside the support frame 11. A locking block 113 is fixedly connected to one end of the spring rod 111. A ratchet 114 is rotatably connected inside the support frame 11 and is fixedly connected to the take-up roller 21. A pulley 122 is rotatably connected inside another set of support frames 11. A belt is fitted on the outer side of pulleys 121 and 122. Pulley 122 is fixedly connected to the take-up roller 21. A ratchet 123 is fixedly connected to one side of pulley 122. An electromagnet is also fixedly connected inside the other set of support frames 11. Electromagnets 112 and 113 are fixedly connected to the drive motor 12. A magnetic plate 131 is slidably connected inside another set of support frames 11. The magnetic plate 131 magnetically engages with electromagnet 13. A spring rod 132 is fixedly connected to one side of the magnetic plate 131, and one end of the spring rod 132 is fixedly connected inside the other set of support frames 11. A connecting rod 133 is fixedly connected to one side of the magnetic plate 131. A trapezoidal block 134 is slidably connected to the top of the connecting rod 133. A locking block 135 is fixedly connected to the top of the trapezoidal block 134, and the locking block 135 matches the ratchet 123. During use... When the overall structure is required, the drive motor 12 located on one side of the other support frame 11 can be started. The drive motor 12 drives the pulley 121 to rotate, which in turn drives the pulley 122 to rotate via the belt connected to it. At this time, the pulley 122 can drive the winding roller 21 inside the winding chamber 2 to rotate, thereby enabling the winding and unwinding operation of the steel rope. When the drive motor 12 is damaged, the drive motor 12 loses power, which in turn causes the electromagnet 13 and the electromagnet 112 to lose power. The electromagnet 112 loses power and loses its attraction effect on the clamp 113. Under the action of the spring rod 111, the clamp 113 and the spring rod 111 stop moving. Ratchet 114 engages, preventing it from rotating. Simultaneously, electromagnet 13 loses power and loses its attraction to magnetic plate 131. Under the action of spring rod 132, connecting rod 133 moves horizontally, causing trapezoidal block 134 to move vertically. Trapezoidal block 134 drives locking block 135 to move, thus fixing locking block 135 to ratchet 123. Since ratchet 123 and ratchet 114 are in opposite directions, it can achieve bidirectional fixing of winding roller 21, realizing bidirectional self-locking of winding roller 21 during overall structure use, thus improving the performance.

[0035] Example 2:

[0036] To address the issue that existing winch self-locking structures often have relatively simple locking mechanisms that cannot quickly brake the take-up roller 21, thus failing to adapt to rapid stops during operation, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 6 As shown, another set of support frames 11 has a mounting chamber 14 fixedly connected to one side. A connecting shaft 141 is rotatably connected inside the mounting chamber 14. The connecting shaft 141 is fixedly connected to a pulley 121. A sliding disk 142 is slidably connected to one end of the connecting shaft 141. A friction disk 143 is also fixedly connected inside the mounting chamber 14. A fixing ring 144 is fixedly connected to one side of the magnetic suction plate 131. The fixing ring 144 matches the sliding disk 142. When the electromagnet 13 is de-energized, it loses its contact with the magnetic suction plate 131. After the adsorption effect is achieved, the magnetic suction plate 131 moves under the action of the spring rod 132, which in turn causes the fixing ring 144 to move. The fixing ring 144 can push the sliding disk 142 to move, which in turn causes the sliding disk 142 to fit tightly with the friction disk 143. At this time, it can brake the pulley 121, preventing the pulley 121 from rotating and causing the take-up roller 21 to continue to rotate. This achieves multiple fixing effects on the take-up roller 21 and further improves the safety factor.
