DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] In the existing hoisting guide, before the guide column reaches the limit position during extension and retraction, it moves at a constant speed. When approaching the limit position during extension and retraction, it cannot decelerate automatically and cannot stop smoothly when reaching the limit position.

[0020] The present utility model provides a new type of guiding system as shown in Figures 1 to 4 Figure, which includes a hoisting machine 1. A telescopic mechanism 2 is installed at the bottom end of the hoisting machine 1. A hoisting tool 4 is installed at the telescopic end of the telescopic mechanism 2. A sliding component 3 is arranged at the top end of the hoisting tool 4. The sliding component 3 is connected to the hoisting machine 1 through a cable.

[0021] During use, a telescopic mechanism 2 is installed at the bottom of the hoisting machine 1. The telescopic mechanism 2 is connected to the lifting tool 4. During the telescoping process of the hoisting machine 1, the cable of the hoisting machine 1 is connected to the sliding assembly 3. As the hoisting machine 1 telescopes, the lifting tool 4 is lifted and lowered through the sliding assembly 3. During the lifting and lowering process of the lifting tool 4, the telescopic mechanism 2 adaptively follows the movement trajectory of the cable to perform corresponding movements, ensuring the movement trajectory of the telescopic mechanism 2 for extension or retraction and driving the lifting tool 4 to move.

[0022] At the same time, the telescopic mechanism 2 guides the movement of the lifting tool 4 to prevent the lifting tool 4 from swaying in the air.

[0023] The telescopic mechanism 2 includes a first guiding column 201, a second guiding column 202, and a third guiding column 203. A first rope head fixing column 204 is provided at the top of the first guiding column 201. A second pulley 206 is provided at the top of the second guiding column 202. A second rope head fixing column 209 is provided at the bottom of the third guiding column 203. The first rope head fixing column 204, the second pulley 206, and the second rope head fixing column 209 are connected by a cable.

[0024] During use, the first guiding column 201 is the fixed end and is fixed to the bottom of the hoisting machine 1. A fixing plate is installed at the bottom of the hoisting machine 1, and the other end of the fixing plate is installed with the first guiding column 201. The first rope head fixing column 204 at one end of the first guiding column 201 is used to connect the cable. The cable passes through the second pulley 206 of the second guiding column 202 and is connected to the second rope head fixing column 209 of the third guiding column 203.

[0025] By retracting and releasing the cable of the hoisting machine 1, the lifting tool 4 is driven to move. The retracting and releasing of the lifting tool 4 drives the third guiding column 203 to move. The third guiding column 203 extends out of the second guiding column 202. At the same time, the second rope head fixing column 209 of the third guiding column 203 drives the cable to move. Therefore, the position of the cable is between the second guiding column 202 and the third guiding column 203. Therefore, the second rope head fixing column 209 of the third guiding column 203 drives the cable to slide out of the second guiding column 202. At this time, the cable extends out of the second guiding column 202 to be lengthened, and the elongation speed of the third guiding column 203 can be controlled.

[0026] A third rope head fixing column 208 is provided at the top of the first guiding column 201. A first pulley 205 is provided at the bottom of the second guiding column 202. A fourth rope head fixing column 207 is provided at one end of the third guiding column 203. The third rope head fixing column 208, the first pulley 205, and the fourth rope head fixing column 207 are connected by a cable.

[0027] During use, while the third guiding column 203 moves, the fourth rope head fixing column 207 of the third guiding column 203 drives the cable to move.

[0028] The fourth rope end fixing post 207 passes through the first pulley 205 to drive the second guiding post 202 to move, and the second guiding post 202 extends out of the interior of the first guiding post 201.

[0029] The first pulley 205 is located inside the first guiding post 201 and is connected to the bottom end of the second guiding post 202.

[0030] The first pulley 205 is arranged inside the first guiding post 201, facilitating the movement of the second guiding post 202. Meanwhile, the cable is located between the two guiding posts, facilitating the sliding of the cable.

[0031] Special polytetrafluoroethylene blocks made of high molecular materials are installed between adjacent guiding posts. This material is smooth, wear-resistant, resistant to high temperature and corrosion, and has a certain hardness. Since this structure is a surface-to-surface friction, it can effectively reduce stress concentration, eliminate jerks, and make the mechanism operate smoothly and reliably.

[0032] The sliding assembly 3 is a pulley block.

[0033] When in use, the sliding assembly 3 is a pulley block, facilitating the hoisting machine 1 to drive the lifting appliance 4 to lift and lower.

[0034] Working principle

[0035] A telescopic mechanism 2 is installed at the bottom end of the hoisting machine 1. The telescopic mechanism 2 is connected to the lifting appliance 4. During the telescoping process of the hoisting machine 1, the cable of the hoisting machine 1 is connected to the sliding assembly 3. When the hoisting machine 1 telescopes, the lifting appliance 4 is lifted and lowered through the sliding assembly 3. During the lifting and lowering process of the lifting appliance 4, the telescopic mechanism 2 adaptively follows the movement trajectory of the cable to make corresponding movements, ensuring that the telescopic mechanism 2 extends or retracts and drives the lifting appliance 4 to move.

[0036] The first guiding post 201 is a fixed end, fixed at the bottom end of the hoisting machine 1. A fixing plate is installed at the bottom end of the hoisting machine 1, and the other end of the fixing plate is installed with the first guiding post 201. The first rope end fixing post 204 at one end of the first guiding post 201 is used to connect the cable. The cable passes through the second pulley 206 of the second guiding post 202 and is connected to the second rope end fixing post 209 of the third guiding post 203.

[0037] By winding and unwinding the ropes of the hoisting machine 1, the spreader 4 is driven to move. The movement of the spreader 4 drives the third guiding column 203 to move. The third guiding column 203 extends out of the second guiding column 202. The fourth rope head fixing column 207 at the top of the third guiding column 203 drives the rope to move. The rope passes through the first pulley 205 and drives the second guiding column 202 to move. At the same time, the second rope head fixing column 209 of the third guiding column 203 drives the rope to move. Therefore, the position of the rope is between the second guiding column 202 and the third guiding column 203. Therefore, the second rope head fixing column 209 of the third guiding column 203 drives the rope to slide out of the second guiding column 202. During the descending process, the telescopic mechanism 2 can be used to achieve a stable and orderly landing of the guiding system.

[0038] At the same time, the rope is located between the two guiding columns, which is convenient for the sliding of the rope. A special high molecular material, polytetrafluoroethylene block, is installed between adjacent guiding columns. This material is smooth, wear-resistant, resistant to high temperature and corrosion, and has a certain hardness. Since this structure is a surface-to-surface friction, it can effectively reduce stress concentration, eliminate jolts, and make the mechanism operate smoothly and reliably.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
