Description

Technical Field

[0001] This invention relates to the field of hoisting technology, and in particular to an anti-entanglement hoisting machine. Background Technology

[0002] A hoist is a large mechanical device that transports goods by changing their potential energy, such as a mine hoist or a dam hoist. Broadly speaking, elevators, overhead cranes, winches, trolleys, cranes, and gate hoists can all be called hoists. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. The transportation process is completed by using a power machine to drive a flexible steel wire rope and the transported goods up and down. The steel wire rope is an indispensable and important component of lifting machinery, and the main types include phosphated coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, and bright steel wire rope, etc.

[0003] Currently available hoists on the market use a fixed drum installation method. The main drawback is that when the wire rope is wound and unwound on the drum, there is a distance between the starting and ending points. This can be understood as the wire rope swinging back and forth on the drum, which creates an angle with other components or pulleys. When the angle is too large, the wire rope may derail and overlap with the wire rope on the pulleys or drum, causing abnormal noise or malfunctions. To address this, we have proposed an anti-winding hoist. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-entanglement lifting machine to overcome the technical problems existing in the prior art.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention provides the following technical solution:

[0006] An anti-entanglement lifting machine includes a base. Moving rails are connected to the front and rear sides of the top of the base. Two movable sliders are slidably connected to the moving rails. A left side plate is connected between the tops of the two left movable sliders, and a right side plate is connected between the tops of the two right movable sliders. A roller is provided between the left and right side plates. A reduction gearbox is connected to the right end of the right side plate. A reduction motor is installed at the drive end of the reduction gearbox. A lead screw fixing seat is connected to the top left side of the base. A reciprocating lead screw is connected to the upper end of the lead screw fixing seat. A trapezoidal nut is threaded onto the outer wall of the reciprocating lead screw. A seated bearing is installed between the trapezoidal nut and the left side plate.

[0007] Preferably, in an anti-winding hoist, a fixing plate is connected to the right side of the inner wall of the drum, a main shaft is connected to the center of the fixing plate, the main shaft is fixed to the output end of the gearbox, an assembly plate is connected to the left side of the inner wall of the drum, a linkage seat is connected to the center of the assembly plate, a trapezoidal nut is connected to the left end of the linkage seat, and a rope groove is opened on the outer wall of the drum, and a steel wire rope is wound in the rope groove.

[0008] Preferably, in an anti-winding lifting machine, two sets of switch brackets are connected to the top left side of the base, a micro limit switch is connected to the outer wall of the switch bracket, and a trigger plate is connected to the lower part of the outer wall of the left side plate, the trigger plate being located above the switch bracket.

[0009] Preferably, in an anti-winding hoist, channel steel pulleys are symmetrically arranged in pairs on the outer wall of the base, guide wheels are installed at the four corners of the bottom of the base, a rope passage is opened in the middle of the base, and a positioning clamp is connected to the lower end of the rope passage, through which the wire rope passes.

[0010] Preferably, in an anti-winding lifting machine, a fixed rod is connected between the upper parts of the left side plate and the right side plate, and a rope pressing wheel is rotatably connected between the lower parts of the left side plate and the right side plate. The fixed rod and the rope pressing wheel are distributed around the drum.

[0011] Preferably, in an anti-winding lifting machine, a welding seat is connected to the top right side of the base, and T-shaped clamps are installed at the front and rear of the top of the welding seat, with the T-shaped clamps located directly above the channel steel pulley.

[0012] Preferably, in an anti-winding hoist, a rope-pressing block is connected to the lower part of the outer wall of the drum.

[0013] Preferably, in an anti-winding lifting machine, a through hole for the main shaft to pass through is provided at the center of the right side plate.

[0014] Preferably, in an anti-winding hoist, the outer surfaces of the rope pressing block and the reciprocating screw are both treated with oxidation and blackening.

[0015] Preferably, in an anti-entanglement hoist, the moving track is an I-beam rail.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention has a reasonable structural design. It uses a roller to wind and unwind the wire rope. The main shaft, fixed plate, and assembly plate rotate synchronously with the roller. The moving track limits and guides the moving slider. The threaded connection between the trapezoidal nut and the reciprocating screw allows the roller to move laterally while the wire rope suspension point remains fixed. The roller moves back and forth while winding the wire rope, which effectively avoids the wire rope from getting tangled and overlapping at the same position in the rope groove, thus ensuring the stability of the lifting operation.

[0018] 2. In this invention, a channel steel pulley is installed on the outer wall of the base and a guide wheel is installed at the bottom, which facilitates the overall movement of the equipment along the channel steel. The T-shaped clamp is located directly above the channel steel pulley, which facilitates braking of the channel steel pulley and ensures the stable transport of materials.

[0019] 3. In this invention, the wire rope passes through the positioning clamp along the rope opening to ensure that the wire rope lifting point is fixed. The lower part of the outer wall of the drum is connected to the rope pressing block to prevent the wire rope from falling out of the groove during winding and unwinding. This ensures the orderly progress of winding and unwinding work and reduces the failure rate. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 As shown, this embodiment is an anti-winding lifting machine, including a base 1. The top front and rear sides of the base 1 are connected to movable rails 2. Two movable sliders 3 are slidably connected on the movable rails 2. A left side plate 4 is connected between the tops of the two movable sliders 3 on the left side, and a right side plate 5 is connected between the tops of the two movable sliders 3 on the right side. A roller 6 is provided between the left side plate 4 and the right side plate 5. A reduction gearbox 7 is connected to the right end of the right side plate 5. A reduction motor 8 is installed on the drive end of the reduction gearbox 7. A lead screw fixing seat 9 is connected to the top left side of the base 1. A reciprocating lead screw 10 is connected to the upper end of the lead screw fixing seat 9. A trapezoidal nut 11 is threaded onto the outer wall of the reciprocating lead screw 10. A seated bearing 12 is installed between the trapezoidal nut 11 and the left side plate 4.

[0032] A fixing plate 61 is connected to the right side of the inner wall of the roller 6. A main shaft 62 is connected to the center of the fixing plate 61. The output end of the reduction gearbox 7 is fixed to the main shaft 62. An assembly plate 63 is connected to the left side of the inner wall of the roller 6. A linkage seat 64 is connected to the center of the assembly plate 63. A trapezoidal nut 11 is connected to the left end of the linkage seat 64. A rope groove 65 is opened on the outer wall of the roller 6. A steel wire rope 66 is wound in the rope groove 65. The reduction gearbox 7 drives the main shaft 62 to rotate, and the roller 6 and the assembly plate 63 rotate accordingly. The trapezoidal nut 11 is threaded to the reciprocating screw 10, so that the roller 6 moves in a lateral position.

[0033] Two sets of switch brackets 41 are connected to the top left side of the base 1. A micro limit switch 42 is connected to the outer wall of the switch bracket 41. A trigger plate 43 is connected to the lower part of the outer wall of the left side plate 4. The trigger plate 43 is located above the switch bracket 41, which facilitates the control of the travel distance of the roller 6 in the lateral movement.

[0034] The outer wall of the base 1 is symmetrically provided with channel steel pulleys 21 in pairs. The bottom corners of the base 1 are equipped with guide wheels 22 to facilitate the overall movement of the equipment along the channel steel. The base 1 has a rope passage 23 in the middle. The lower end of the rope passage 23 is connected to a positioning clamp 24. The wire rope 66 passes through the positioning clamp 24 along the rope passage 23 to ensure that the lifting point position of the wire rope 66 is fixed.

[0035] A fixing rod 51 is connected between the upper parts of the left side plate 4 and the right side plate 5, and a rope pressing wheel 52 is rotatably connected between the lower parts of the left side plate 4 and the right side plate 5. The fixing rod 51 and the rope pressing wheel 52 are distributed around the drum 6 to ensure the winding and unwinding of the wire rope 66 drum 6.

[0036] A welding seat 13 is connected to the top right side of the base 1. T-shaped clamps 14 are installed at the front and back of the top of the welding seat 13. The T-shaped clamps 14 are located directly above the channel steel pulley 21, which facilitates braking of the channel steel pulley 21 and thus positioning the equipment.

[0037] The lower part of the outer wall of the roller 6 is connected to a rope pressing block 67 to prevent the wire rope 66 from coming off the groove when it is wound up.

[0038] The right side plate 5 has a through hole at its center for the main shaft 62 to pass through, so as to avoid interfering with the rotation of the main shaft 62.

[0039] The outer surfaces of the rope pressing block 67 and the reciprocating lead screw 10 are both treated with oxidation and blackening to prevent rust by eliminating air.

[0040] The moving track 2 is an I-beam track to prevent the moving slider 3 from derailing when it slides.

[0041] The specific implementation method of this embodiment is as follows:

[0042] This device is powered by an external power source. The base 1 has channel steel pulleys 21 installed on its outer wall and guide wheels 22 installed at its bottom, facilitating overall movement along the channel steel. The roller 6 winds and unwinds the wire rope 66, enabling material lifting and transportation. During the winding and unwinding of the wire rope 66, the reduction motor 8 starts and drives the main shaft 62 to rotate via the reduction gearbox 7. The main shaft 62 is connected to the roller 6 via a fixing plate 61. When the roller 6 rotates counterclockwise, the wire rope 66 winds and lifts upwards. The mounting plate 63 is fixed to the inner wall of the roller 6, and the end of the linkage seat 64 is connected to a trapezoidal nut 11. The moving track 2 limits and guides the moving slider 3. The threaded connection between the trapezoidal nut 11 and the reciprocating screw 10 causes the left side plate 4 to move the roller 6 laterally. The wire rope 66 passes through the rope opening 23 and the positioning clamp 24, ensuring the lifting point remains fixed. The roller 6 can reciprocate while winding the wire rope, preventing the wire rope 66 from tangling and overlapping at the same position in the rope groove 65, thus ensuring the stability of the lifting operation.
