Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical parking equipment, specifically relating to a cable tightening device for a parking equipment transporter. Background Technology
[0002] With the surge in the number of cars, mechanical parking equipment has been widely used due to its high space utilization. Among them, the transfer device, as a key component for vehicle transfer within the parking equipment, requires power to be transmitted to it via cables to drive its reciprocating sliding motion. Therefore, the stability of the cables directly affects the operation of the equipment.
[0003] Currently, cable winding mostly adopts a drum-type winding and unwinding structure, that is, the middle section of the cable is fixed to the drum, and the two ends of the cable are connected to the transporter and power supply device. The winding or unwinding of the cable is achieved by the forward and reverse rotation of the drum to coordinate with the movement of the transporter.
[0004] However, during actual operation, due to factors such as mechanical friction and load changes, the winding and unwinding speed of the cable on the drum and the moving speed of the transporter are not strictly synchronized. When the drum release speed is slower than the moving speed of the transporter, the cable will sag and cannot provide stable traction, causing the transporter to jam and the cable to be dragged and worn, making it easy to be damaged. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a cable tightening device for a parking equipment transporter. Through the tightening device, the cable is dynamically adjusted to ensure that the cable is always taut, avoiding dragging and wear caused by the cable slack and sagging, thus ensuring the service life of the cable and the operational stability of the transporter.
[0006] The specific technical solution adopted in this utility model is as follows:
[0007] A cable tensioning device for a parking equipment includes a guide wheel assembly and a tensioning device mounted on a transport trolley. The transport trolley is also equipped with a slidable transporter. The guide wheel assembly includes a fixed pulley assembly and a slidable movable pulley. The cable passes through the movable pulley and the fixed pulley assembly and is connected to the transporter. The movable pulley has the freedom to move back and forth with the help of the tensioning device.
[0008] The transport trolley is equipped with a slide rail parallel to the sliding direction of the transporter. The movable pulley slides in cooperation with the slide rail via a sliding seat, and the traction end of the tensioning device is connected to the sliding seat.
[0009] The fixed end of the cable is fixedly connected to the transport trolley, and the output end of the cable passes through the movable pulley and the fixed pulley group in sequence along the N-shaped trajectory and is connected to the transporter.
[0010] The fixed pulley assembly includes a fixed pulley and a reversing pulley. The fixed pulley and the movable pulley are located in the same plane and their axes are parallel to each other. The plane where the reversing pulley is located is perpendicular to the plane where the fixed pulley is located. The output end of the cable passes through the movable pulley and the fixed pulley in sequence along the horizontal plane, and then changes direction with the help of the reversing pulley and connects to the transporter along the vertical direction of the transport trolley.
[0011] The deflector wheels are arranged in pairs. The two sets of deflector wheels are arranged side by side along the sliding direction of the movable pulley and are located in the same vertical plane. The output end of the cable passes through the gap between the two sets of deflector wheels and is guided by the clamping of the two sets of deflector wheels to form a deflection.
[0012] The tensioning device includes a guide roller and a connecting rope wound around the guide roller. The connecting rope forms the traction end of the tensioning device and is connected to a movable pulley. A reset spring is provided on the rotating shaft of the guide roller. The sliding pulley pulls the connecting rope and drives the guide roller to rotate. When the guide roller rotates, it compresses the reset spring and generates a reset tendency with the help of the reset spring.
[0013] The slide rail includes two slide rods parallel to the sliding direction of the transporter. The two ends of the slide rods are fixedly connected to the two sides of the transport trolley, respectively. The slide block is sleeved with the slide rod to form a sliding fit. The movable pulley has the freedom to move in the horizontal direction with the help of the slide block.
[0014] The beneficial effects of this utility model are:
[0015] This utility model adds a guide wheel assembly and a tensioning device for tightening the cable. The tensioning device and the fixed end of the cable are located at the two ends of the sliding track of the movable pulley and form a reverse tension. Through the tensioning device, the cable is dynamically adjusted so that the cable is always kept taut, avoiding dragging and wear caused by the cable slack and drooping, thus ensuring the service life of the cable and the operational stability of the transporter.
[0016] When the transporter moves, the output end of the cable moves to the far end, the cable length between the movable pulley and the reversing wheel shortens, and the contraction of the cable drives the slide block where the movable pulley is located to move towards the fixed end of the cable. During this process, the traction end of the tensioning device will always pull the movable pulley with a reverse pulling force. When the cable slacks and tends to detach from the movable pulley, or when the moving speed of the movable pulley under the action of inertia is greater than the contraction speed of the cable, the tensioning device will pull the slide block where the movable pulley is located to move in the opposite direction, so that the cable is tightened again and fits against the movable pulley.
[0017] When the transporter resets, the cable length between the movable pulley and the reversing wheel returns to its original length. At this time, the traction force of the tensioning device is greater than the tension force of the cable on the movable pulley. The movable pulley slides along the slide rail toward the tensioning device end. During the reset sliding process, the cable is always kept in a taut state in contact with the movable pulley.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0022] Specific embodiments, such as Figure 1-2 As shown, a cable 5 tightening device for a parking equipment includes a guide wheel assembly and a tensioning device 2 mounted on a transport trolley 1. The transport trolley 1 is also equipped with a slidable transporter. The guide wheel assembly includes a fixed pulley assembly and a slidable movable pulley 3. The cable 5 passes through the movable pulley 3 and the fixed pulley assembly and is connected to the transporter. The movable pulley 3 has the freedom to move back and forth with the help of the tensioning device 2.
[0023] Currently, cable 5 is mostly wound using a drum-type winding and unwinding structure. The middle section of cable 5 is fixed to the drum, while both ends of cable 5 are connected to the transporter and power supply. The winding or unwinding of cable 5 is achieved by rotating the drum in both directions to coordinate with the movement of the transporter. However, during actual operation, due to factors such as mechanical friction and load changes, a speed difference will occur between the winding and unwinding speed of cable 5 on the drum and the moving speed of the transporter. When the unwinding speed of the drum is slower than the moving speed of the transporter, cable 5 will sag and become loose, failing to provide stable traction. This causes the transporter to jam, and cable 5 will be directly dragged and worn, easily leading to damage.
[0024] Therefore, this utility model adds a guide wheel group and a tensioning device 2 for tightening the cable 5. The tensioning device 2 and the fixed end of the cable 5 are respectively located at both ends of the sliding track of the movable pulley 3 and form a reverse tension.
[0025] When the transporter moves, the output end of cable 5 moves to the far end, and the length of cable 5 between the movable pulley 3 and the reversing wheel 7 shortens. The contraction of cable 5 will drive the slide 4 where the movable pulley 3 is located to move towards the fixed end of cable 5. During this process, the traction end of the tensioning device 2 will always pull the slide 4 with a reverse pulling force. When cable 5 slackens and tends to detach from the movable pulley 3, or when the moving speed of the movable pulley 3 under the action of inertia is greater than the contraction speed of cable 5, the tensioning device 2 will pull the slide 4 where the movable pulley 3 is located to move in the opposite direction, so that cable 5 is tightened again and fits against the movable pulley 3.
[0026] When the transporter resets, the length of the cable 5 between the movable pulley 3 and the reversing wheel 7 returns to its original length. At this time, the traction force of the tensioning device 2 is greater than the tension force of the cable 5 on the movable pulley 3. The movable pulley 3 slides along the slide rail toward the end of the tensioning device 2. During the reset sliding process, the cable 5 is always kept in a taut state in contact with the movable pulley 3.
[0027] The tightening device in this invention enables dynamic adjustment of the cable 5, ensuring that the cable 5 is always taut and preventing dragging and wear caused by slackness and sagging. This guarantees the service life of the cable 5 and the operational stability of the transporter.
[0028] The transport trolley 1 is equipped with a slide rail parallel to the sliding direction of the transporter. The movable pulley 3 slides with the slide rail via the slide seat 4, and the traction end of the tensioning device 2 is connected to the slide seat 4.
[0029] The fixed end of the cable 5 is fixedly connected to the transport trolley 1, and the output end of the cable 5 passes through the movable pulley 3 and the fixed pulley group in sequence along the N-shaped trajectory and is connected to the transporter.
[0030] The input end of cable 5 is connected to the output end of the power supply equipment.
[0031] Cable 5 forms an N-shaped distribution trajectory with the help of the guide wheel group, which can realize the storage of cable 5 with twice the length in a smaller space, thereby reducing space occupation and reducing economic costs.
[0032] The fixed pulley assembly includes a fixed pulley 6 and a reversing pulley 7. The fixed pulley 6 and the movable pulley 3 are located on the same plane and their axes are parallel to each other. The plane where the reversing pulley 7 is located is perpendicular to the plane where the fixed pulley 6 is located. The output end of the cable 5 passes through the movable pulley 3 and the fixed pulley 6 in sequence along the horizontal plane, and then changes direction with the help of the reversing pulley 7 and connects to the transporter along the vertical direction of the transport trolley 1.
[0033] If the fixed wheel 6 and the movable pulley 3 are not on the same plane, the cable 5 will experience localized tension concentration due to oblique winding, which can easily lead to wear and breakage of the cable 5 after long-term use. Since the transport trolley 1 has a plate-like structure with a large horizontal area and a thin vertical thickness, the fixed wheel 6 and the movable pulley 3 need to be set along the horizontal plane to save space. However, since the cable 5 needs to be led out to connect with the transporter, a deflecting wheel 7 is provided to change the direction of the cable 5 so that it can be led out and connected to the transporter.
[0034] The deflector wheels 7 are arranged in pairs. The two sets of deflector wheels 7 are arranged side by side along the sliding direction of the movable pulley 3 and are located in the same vertical plane. The output end of the cable 5 passes through the gap between the two sets of deflector wheels 7 and is guided by the clamping of the two sets of deflector wheels 7 to form a deflection.
[0035] If there is only one set of directional pulleys 7, when the transporter slides away from the directional pulleys 7, the cable 5 will gradually detach from the directional pulleys 7, which may cause derailment. By using two sets of directional pulleys 7 to form a bidirectional clamping and limiting of the cable 5, regardless of whether the output end of the cable 5 moves forward or backward with the transporter, the cable 5 is always confined within the gap and closely attached to one set of directional pulleys 7.
[0036] The tensioning device 2 includes a guide roller 201 and a connecting rope 202 wound on the guide roller 201. The connecting rope 202 forms the traction end of the tensioning device 2 and is connected to the movable pulley 3. A reset coil spring is provided on the rotating shaft of the guide roller 201. The sliding pulley 3 pulls the connecting rope 202 and drives the guide roller 201 to rotate. When the guide roller 201 rotates, it compresses the reset coil spring and generates a reset tendency with the help of the reset coil spring.
[0037] The bottom of the slide 4 is equipped with a hook, and the traction end of the connecting rope 202 is equipped with a hook ring that engages with the hook.
[0038] When the movable pulley 3 slides and pulls the connecting rope 202, the connecting rope 202 drives the guide roller 201 to rotate. The reset spring is compressed and generates a reset elastic force opposite to the pulling force of the movable pulley 3. When the load of the transporter increases, the tension of the cable 5 needs to increase synchronously. At this time, the pulling force of the movable pulley 3 on the connecting rope 202 increases, the compression of the spring increases, and the reset elastic force increases synchronously to ensure that the tension matches the load.
[0039] During the reset process of the transporter, the tension provided by the cable 5 to the movable pulley 3 is less than the reset spring force. The coil spring will release the compression amount, and the guide roller 201 will rotate in the opposite direction, thereby causing the connecting rope 202 to be wound up. The connecting rope 202 pulls the movable pulley 3 to reset and slide, ensuring that the cable 5 and the movable pulley 3 are always in contact.
[0040] The slide rail includes two slide rods 8 parallel to the sliding direction of the transporter. The two ends of the slide rods 8 are fixedly connected to the two sides of the transport trolley 1, respectively. The slide seat 4 is sleeved with the slide rods 8 to form a sliding fit. The movable pulley 3 has the freedom to move in the horizontal direction with the help of the slide seat 4.
[0041] The end of the slide rod 8 is fixedly connected to the transport trolley 1 by bolts. The slide rail uses two slide rods 8 parallel to the sliding direction of the transporter. Compared with a single slide rod 8, the slide rail formed by the double slide rods 8 is more stable and can prevent the slide block 4 from shaking during the sliding process.
