Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically relating to a wire rope winding and anti-tangling limit device for construction cranes. Background Technology

[0002] The winch system is the lifting mechanism of a crane. It transmits power by winding a wire rope, converting rotary motion into linear motion, and completing tasks such as lifting, stopping, and lowering heavy objects. However, during the winding process of the wire rope, the winch drum is prone to tangling. The wire rope cannot be wound regularly on the drum, and the wire ropes squeeze each other, which can easily cause wear and affect the service life of the wire rope. Utility Model Content

[0003] The purpose of this invention is to provide a wire rope winding anti-tangling limiting device for construction cranes, which can guide the wire rope during winding to ensure that the wire rope is evenly wound on the winch. Furthermore, this device can be applied to different types of cranes, effectively improving its applicability.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A wire rope winding prevention and tangling limiting device for a construction crane includes a base. One end of the base is fixedly connected to a support plate, and the other end of the support plate is fixedly connected to the outer side of a support frame. The middle of the left and right sides of the support frame is rotatably connected to the two ends of a reciprocating screw via bearings. The reciprocating screw is threadedly connected to a reciprocating screw nut, which is fixedly disposed in the middle of a translation plate. The translation plate is fixedly connected to a fixed frame, and the fixed frame is also rotatably connected to a support shaft via bearings. One end of the support shaft is fixedly connected to a connecting frame.

[0006] Furthermore, the end of the support shaft is fixedly connected to a gear, and the gear meshes with a gear plate.

[0007] Furthermore, the toothed plate is provided with both a screw hole and a sleeve hole, and the screw hole is threadedly connected to the screw rod.

[0008] Furthermore, the optical axes at both ends of the screw are rotatably connected to one end of each of the two fixed plates via bearings, and the other ends of the two fixed plates are fixedly connected to the fixing frame.

[0009] Furthermore, the second sleeve hole is sleeved with the second slide rod, and the two ends of the second slide rod are respectively fixedly connected to two fixed plates.

[0010] Furthermore, the right end of the reciprocating screw is fixedly connected to the motor output shaft, and the motor is fixedly connected to the support frame via a mounting base.

[0011] Furthermore, the translation plate also has two sleeve holes, which are respectively connected to two sliding rods.

[0012] Furthermore, the two ends of the two slide rods are respectively fixedly connected to the two ends of the support frame.

[0013] Furthermore, the left and right ends of the connecting frame are respectively fixedly connected to the opposite ends of the two electric push rods, and the opposite ends of the two electric push rods are respectively fixedly connected to the two pulleys.

[0014] Furthermore, both pulleys are connected to the wire rope, and mounting holes are provided at the four corners of the base.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention features an electric push rod and pulleys mounted on a connecting frame. During operation, the crane wire rope passes through the two pulleys, and the two electric push rods extend, bringing the pulleys closer together to clamp and limit the wire rope. When the wire rope is wound up using a winch, the motor, reciprocating screw, reciprocating screw nut, and translation plate drive the connecting frame and pulleys to move left and right, adjusting the position of the wire rope. This allows the wire rope to wind sequentially along the winch drum, preventing irregular and messy winding that could cause compression and effectively extending the wire rope's lifespan. Furthermore, by connecting the connecting frame and translation plate with a fixed frame and support shaft, the angle of the connecting frame and pulleys can be adjusted according to the wire rope's orientation, ensuring the pulleys remain horizontal and guaranteeing their limiting and guiding effect on the wire rope.

[0017] When using this invention, the device's state can be adjusted according to the angle of the wire rope. For example, when tower cranes and truck cranes are used, their wire ropes are horizontal or at a certain angle in the horizontal direction. In this case, the device can be adjusted to state one. When gantry cranes are used, their wire ropes are vertical. In this case, the device can be adjusted to state two. This effectively improves the applicability of the device to cranes of different sizes and models. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, a wire rope winding prevention and tangling limiting device for a construction crane includes a base 1. The base 1 is fixedly connected to one end of a support plate 2, and the other end of the support plate 2 is fixedly connected to the outer side of a support frame 4. The middle of the left and right sides of the support frame 4 is rotatably connected to the two ends of a reciprocating screw 5 via bearings. The reciprocating screw 5 is threadedly connected to a reciprocating screw nut 12, which is fixedly installed in the middle of a translation plate 10. The translation plate 10 is fixedly connected to a fixed frame 7, which is also rotatably connected to a support shaft 14 via bearings. The support shaft 14 is fixedly connected to one end of a connecting frame 8.

[0027] The end of the support shaft 14 is fixedly connected to the gear 13, and the gear 13 meshes with the toothed plate 20. When in use, the angle of the connecting frame 8 and the pulley 21 can be adjusted according to the placement angle of the wire rope 9 so that the pulley 21 can keep the wire rope 9 horizontal, thereby ensuring the limiting and guiding effect of the pulley 21 on the wire rope 9. The state of the device can also be adjusted according to the usage angle of the wire rope 9. For example, when the wire rope 9 of a tower crane or a truck crane is horizontal or at a certain angle in the horizontal direction, the device can be adjusted to state one. When the wire rope 9 of a gantry crane is vertical, the device can be adjusted to state two. This effectively improves the applicability of the device to cranes of different sizes and models.

[0028] The toothed plate 20 has a screw hole 19 and a sleeve hole 18, and the screw hole 19 is threadedly connected to the screw rod 17.

[0029] The optical shafts at both ends of the screw 17 are rotatably connected to one end of the two fixing plates 15 via bearings, and the other ends of the two fixing plates 15 are fixedly connected to the fixing frame 7.

[0030] The second sleeve hole 18 is sleeved with the second slide rod 16. The two ends of the second slide rod 16 are respectively fixedly connected to the two fixed plates 15. By opening the second sleeve hole 18 in the toothed plate 20 and sleeved with the second slide rod 16, the movement of the toothed plate 20 is limited by the sleeve hole 18 and the second slide rod 16, so as to avoid the screw 17 from rotating and affecting the translation and sliding of the toothed plate 20.

[0031] The right end of the reciprocating screw 5 is fixedly connected to the output shaft of the motor 3. The motor 3 is fixedly connected to the support frame 4 through the mounting base. By setting an electric push rod 22 and a pulley 21 on the connecting frame 8, the crane wire rope 9 is passed through the two pulleys 21 when the device is in use. The two electric push rods 22 are controlled to extend so that the two pulleys 21 move closer to each other to clamp and limit the wire rope 9. When the wire rope 9 is wound up by the winch, the motor 3, the reciprocating screw 5, the reciprocating screw nut 12, and the translation plate 10 can drive the connecting frame 8 and the pulley 21 to move back and forth. The position of the wire rope 9 can be adjusted by the translation of the connecting frame 8 and the pulley 21, so that the wire rope 9 can be wound sequentially along the winch drum. This avoids the compression caused by the irregular and messy winding of the wire rope 9 on the drum, and effectively extends the service life of the wire rope 9.

[0032] The translation plate 10 also has two sleeve holes 11, which are respectively connected to two slide rods 6.

[0033] The two ends of the two slide rods 6 are fixedly connected to the two ends of the support frame 4, respectively.

[0034] The left and right ends of the connecting frame 8 are fixedly connected to the opposite ends of the two electric push rods 22, and the opposite ends of the two electric push rods 22 are fixedly connected to the two pulleys 21. When using this device, the wire rope 9 can be placed between the two pulleys 21, and the extension of the two electric push rods 22 can be controlled to bring the two pulleys 21 closer to each other. When both pulleys 21 are in close contact with the wire rope 9, the extension of the electric push rods 22 is stopped, thereby using the pulleys 21 to clamp and limit the wire rope 9, and then using the translation of the connecting frame 8 and the pulleys 21 to guide the wire rope 9.

[0035] Both pulleys 21 are connected to the wire rope 9, and mounting holes are provided at the four corners of the base 1.

[0036] The working principle of this utility model is as follows: When this device is installed on a crane such as a tower crane or a truck crane where the wire rope 9 is placed horizontally, the user can install the base 1 on the crane arm on one side of the winch, then place the wire rope 9 between two pulleys 21, and control the extension of the two electric push rods 22 to bring the two pulleys 21 closer to each other. When both pulleys 21 are in close contact with the wire rope 9, the extension of the electric push rods 22 is stopped. At this time, the device is in state one.

[0037] When this device is installed on a gantry crane or other crane where the wire rope 9 is placed vertically, the user can invert the device so that the base 1 is installed on the crossbeam of the gantry crane, and rotate the screw 17 to drive the toothed plate 20 to move horizontally through the screw hole 19. When the toothed plate 20 moves horizontally, it drives the support shaft 14 and the connecting frame 8 to rotate through the gear 13, so that the connecting frame 8 rotates to a horizontal state. At this time, the wire rope 9 can be placed between the two pulleys 21, and the electric push rod 22 is controlled to extend so that the pulleys 21 squeeze and limit the wire rope 9. At this time, the device is in state two.

[0038] When the winch winds up the wire rope 9, the control motor 3 drives the reciprocating screw 5 to rotate. When the reciprocating screw 5 rotates, it drives the translation plate 10, the fixed frame 7 and the connecting frame 8 to reciprocate through the reciprocating screw nut 12. At this time, the translation of the connecting frame 8 and the pulley 21 guides the wire rope 9.

[0039] The above description is merely a preferred embodiment 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. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
