A cable management device for tower cranes

Abstract

This utility model discloses a cable sorting device for tower cranes, including a bracket with a U-shaped structure. A take-up roller is rotatably connected to the bracket. A pair of columns are provided on one side of the take-up roller. A groove is opened on one side wall of the column, and a support arm is slidably connected in the groove. A screw is rotatably connected between the two support arms. A guide plate is threaded onto the screw, and a cable is inserted into the guide plate. One end of the cable passing through the guide plate is wound around the take-up roller. This utility model has the following advantages: When the cable passes through the guide plate, during the take-up or unwinding operation, the driver is activated to drive the screw to rotate. Through the threaded connection between the screw and the sleeve, the guide plate is driven to move back and forth along the screw, which can drive the cable to move synchronously, thereby adjusting the position of the cable. This can effectively distribute the cable evenly on the take-up roller, thereby avoiding the cable from concentrating in one place on the take-up roller and affecting the stability of the cable winding.

Description

Technical Field

[0001] This utility model relates to the technical field of cable sorting equipment, specifically to a cable sorting device for tower cranes. Background Technology

[0002] Tower cranes, also known as tower hoists, are one of the main pieces of equipment in the construction industry. They can transport building materials vertically and horizontally, and can also turn, effectively improving the delivery of building materials and thus accelerating the construction progress. They mainly use drive components to drive special cables to lift and transport building materials.

[0003] Because cables need to be frequently switched between winding and unwinding, their movement needs to be guided to ensure smooth operation. However, current cable drive equipment lacks the necessary equipment, which can easily lead to the cable getting tangled in one or adjacent locations. This increases the pressure on that area and causes the tension generated by the cable to become too concentrated, affecting the stability of the equipment. Utility Model Content

[0004] This utility model provides a cable sorting device for tower cranes, which can solve problems such as the cable getting tangled and gathered in one place, causing excessive pressure in that area, and the cable gathering causing an imbalance in the pulling force on the winding roller, affecting the force balance of the winding roller, and causing the winding equipment to malfunction.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a cable sorting device for tower cranes, including a bracket, the bracket having a U-shaped structure, a take-up roller rotatably connected to the bracket, a pair of columns provided on one side of the take-up roller, a sliding groove provided on one side wall of the column, a support arm slidably connected in the sliding groove, a screw rotatably connected between the two support arms, a guide plate threaded onto the screw, a cable inserted into the guide plate, and one end of the cable passing through the guide plate being wound around the take-up roller.

[0006] As a preferred embodiment of this utility model, a rotating block is fixedly connected to the middle of the bottom surface of the guide plate, a fixed block is rotatably connected to the middle of the bottom end of the rotating block, and a sleeve block is fixedly connected to the bottom surface of the fixed block, with the sleeve block threaded onto the screw rod.

[0007] As a preferred technical solution of this utility model, a positioning rod is fixedly connected between the two support arms and on the side wall below the screw, and the positioning rod is inserted into the sleeve block near the bottom. A driver is detachably connected to one side wall of the support arm, and the output shaft of the driver is detachably connected to one end of the screw through the support arm.

[0008] As a preferred technical solution of this utility model, a through groove is provided in the middle of the screw, and a ball bearing is rotatably connected to the inner wall of the through groove near both ends, and the ball bearing is in contact with a section of the cable located in the through groove.

[0009] As a preferred embodiment of this utility model, one end of the bracket is detachably connected to a motor, the output end of the motor is connected to the center point of one end of the winding roller, and both the bracket and the column are detachably connected to the tower crane by screws.

[0010] This invention has the following advantages: When the cable passes through the guide plate, the driver is activated to rotate the screw during winding or unwinding operations. The screw and the sleeve block are connected by a thread, which drives the guide plate to move back and forth along the screw. This causes the cable to move synchronously, thereby adjusting the position of the cable. This effectively distributes the cable evenly on the winding roller, preventing the cable from concentrating in one place on the winding roller, which would affect the stability of the cable winding and winding. It also avoids safety problems caused by the unbalanced force on the winding roller due to the concentration of cable. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3 The present invention relates to a cable management device for tower cranes, comprising a support 1, the support 1 having a U-shaped structure, a take-up roller 3 rotatably connected to the support 1, a pair of columns 4 provided on one side of the take-up roller 3, a screw 7 rotatably connected between the two support arms 6, a guide plate 8 threaded onto the screw 7, a cable being inserted into the guide plate 8, and one end of the cable passing through the guide plate 8 being wound around the take-up roller 3; A rotating block 12 is fixedly connected to the middle of the bottom surface of the guide plate 8. A fixed block 11 is rotatably connected to the middle of the bottom end of the rotating block 12. A sleeve block 10 is fixedly connected to the bottom surface of the fixed block 11. The sleeve block 10 is threaded onto the screw rod 7. A positioning rod is fixedly connected to the side wall between the two support arms 6 and below the screw rod 7. The positioning rod is inserted into the sleeve block 10 near the bottom. A driver 9 is detachably connected to one side wall of the support arm 6. The output shaft of the driver 9 passes through the support arm 6 and is detachably connected to one end of the screw rod 7. A through groove 13 is opened in the middle of the screw rod 7. A ball bearing 14 is rotatably connected to the inner wall of the through groove 13 near both ends. The ball bearing 14 fits against the section of the cable located in the through groove 13.

[0015] The technical effect of this solution is as follows: The starter 9 drives the screw 7 to rotate. As the screw 7 rotates, the guide plate 8 moves along the screw 7 through the threaded connection. Because the positioning rod is connected to the support arm 6 and the positioning rod is inserted into the sleeve block 10, the smooth movement of the sleeve block 10 can be ensured. This prevents the sleeve block 10 from rotating with the screw 7 due to friction, which would affect the sorting effect on the cable. As the guide plate 8 moves, it will move the cable synchronously. This allows the cable to be evenly distributed on the take-up roller 3 instead of being concentrated. The even sorting of the cable can disperse the pulling force on the take-up roller 3 and avoid the cable from being concentrated, which would affect the take-up and unwinding operations. Because the guide plate 8 and the sleeve block 10 are in a rotating relationship through the fixed block 11 and the rotating block 12, the guide plate 8 can adaptively rotate and adjust according to the condition of the cable, ensuring that the tilt state of the guide plate 8 corresponds to that of the cable, reducing the obstruction caused by the guide plate 8 to the cable, and improving the smoothness of the cable operation. It should be noted that the speed of the driver 9 must correspond to that of the winding roller 3, so as to ensure that the cable is evenly spirally wound on the winding roller 3.

[0016] Reference Appendix Figure 1 As shown: A sliding groove 5 is provided on one side wall of the column 4. A support arm 6 is slidably connected in the sliding groove 5. A motor 2 is detachably connected to one end of the bracket 1. The output end of the motor 2 is connected to the center point of one end of the winding roller 3. Both the bracket 1 and the column 4 are detachably connected to the tower crane by screws.

[0017] The technical advantages of this solution are as follows: A groove 5 is provided on the column 4, allowing the height of the support arm 6 to be adjusted as needed. Because the cable is inserted into the guide plate 8, when the cable is taut, it will pull the guide plate 8 upward, thereby lifting the support arm 6 as well, achieving an adaptive height adjustment effect. This also allows for the movement of the cable, reducing the burden on the cable caused by rigid limits. When the cable is slack, the support arm 6 will automatically descend under gravity. Of course, a telescopic component can also be installed in the groove 5 to achieve active control of the lifting and lowering of the support arm 6, depending on the actual situation.

[0018] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0019] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
