DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 As shown, it is a structural diagram of a tower crane auxiliary ladder climbing device provided by an embodiment of the present invention, including a protective plate 1 and a belt 2, the surface of the belt 2 is provided with a suspension rope 21, the bottom wall of the protective plate 1 is fixedly installed with a balancing cone 3, the bottom wall of the protective plate 1 is rotatably installed with multiple groups of support rods 4, the end of the support rod 4 away from the protective plate 1 is provided with a first clamping rod 41, the first clamping rod 41 is an inverted V-shaped structure, and the multiple groups of support rods 4 are arranged around the balancing cone 3 in a circular shape with equal intervals, and a control mechanism 5 that cooperates with the support rods 4 is provided in the balancing cone 3, the control mechanism 5 includes a pulling component 51, a limiting component 52 and a protective component 53, the pulling component 51 is located in the balancing cone 3, one end of the pulling component 51 is connected to the support rod 4, and the other end of the pulling component 51 is connected to the suspension rope 21, and the pulling component 51 is connected to the suspension cone 3 by The ropes 21 cooperate with each other to pull the multiple groups of support rods 4 to rotate toward the balance cone 3. The limit assembly 52 includes a support portion 521 and an adjustment portion 522. The support portion 521 is located on the side wall of the balance cone 3 and is connected to the support rod 4. The support portion 521 is used to position the support rod 4 outside the balance cone 3. The adjustment portion 522 is located in the balance cone 3 and is connected to the support portion 521. The adjustment portion 522 adjusts the inclination angle of the support rod 4 by cooperating with the support portion 521, thereby adjusting the relative distance between the first clamping rod 41 and the balance cone 3. The protective assembly 53 is located on the side wall of the balance cone 3 and contacts with the support rod 4. When the pulling assembly 51 releases the pulling force on the support rod 4, the protective assembly 53 is used to push the support rod 4 to rotate away from the balance cone 3, thereby increasing the relative distance between the first clamping rod 41 and the balance cone 3.

[0024] When the staff climbs in the inner cavity of the tower crane, they first tie the belt 2 to the tail of the waist. During the climbing process, the belt 2 cooperates with the lifting rope 21 to suspend the protective plate 1. The protective plate 1 is below the staff, and the balance cone 3 controls the protective plate 1 to maintain a horizontal state. During the climbing process, the pulling component 51 cooperates with the supporting part 521 to position the support rod 4 outside the balance cone 3. At this time, multiple groups of support rods 4 are inclined outside the balance cone 3. During the climbing process, the support rod 4 and the first clamping rod 41 are both in the inner cavity of the tower crane. The support rod 4 and the first clamping rod 41 will not interfere with the rods of the tower crane. During a long climbing process, when the staff is tired and wants to rest, the staff stands in the inner cavity of the tower crane, and the staff can pull the lifting rope 21, and the lifting rope 21 drives the protective plate 1 moves upward, the staff first holds the protective plate 1, and then controls the lifting rope 21 to adjust the pulling force of the pulling component 51 on the support rod 4. At this time, the protective component 53 cooperates with the pulling component 51 to control the support rod 4 to rotate a certain range in the direction away from the balance cone 3, so that the first clamping rod 41 is just above the rod on the surface of the tower crane, and the first clamping rod 41 is clamped on the rod on the surface of the tower crane. Multiple groups of support rods 4 can stably support and position the protective plate 1. At this time, the staff can sit on the surface of the protective plate 1 to rest. After the rest, the staff continues to climb upward. At this time, the lifting rope 21 suspends the protective plate 1, and the lifting rope 21 is in a straightened state. The lifting rope 21 cooperates with the pulling component 51 to apply pulling force to the support rod 4, and the support rod 4 rotates to the original position in the direction of the balance cone 3. During the continuous climbing process, the protective plate 1 is always under the staff and moves upward synchronously. When an accident occurs during climbing and the staff steps on air and falls down, the lifting rope 21 and the pulling assembly 51 cooperate with each other to release the pulling force on the support rod 4, and the protective assembly 53 quickly controls the support rod 4 to rotate away from the balance cone 3. The bottom ends of the multiple groups of support rods 4 extend to the outside of the tower crane rod. The flat bottom wall of the protective plate 1 can limit the rotation range of the support rod 4, and the multiple groups of support rods 4 remain in a horizontal state. The multiple groups of support rods 4 can stably support the protective plate 1, and the staff will fall directly on the surface of the protective plate 1. The height between the position where the staff falls and the protective plate 1 is relatively short, and no injuries will occur, which can effectively prevent the staff from falling continuously in the inner cavity of the tower crane and causing accidents.

[0025] like Figure 1 , Figure 2 , Figure 4As shown, as a preferred embodiment of the present invention, the pulling assembly 51 includes a vertical hole 511 opened downward from the surface of the protective plate 1 and extending to the inside of the balance cone 3, and the side wall of the balance cone 3 is opened inward with multiple groups of circularly distributed horizontal holes 512, and the horizontal holes 512 are connected to the bottom ends of the vertical holes 511, and a pulling rope 513 is fixedly installed on the side wall of the support rod 4, and the end of the pulling rope 513 away from the support rod 4 passes through the horizontal hole 512 and the vertical hole 511 to extend to the outside of the protective plate 1 and is connected to the bottom end of the suspension rope 21.

[0026] When climbing, the staff tie the belt 2 around the tail end of the waist. During the climbing process, the belt 2 cooperates with the lifting rope 21 to suspend the protective plate 1. The lifting rope 21 cooperates with the pulling rope 513 to apply tension to the support rod 4 so that the support rod 4 rotates toward the balance cone 3. The support part 521 supports and positions the support rod 4 on the outside of the balance cone 3. Since the protective plate 1 and the support rod 4 are a whole, when the staff climbs upward in the inner cavity of the tower crane, the staff will move upward synchronously with the lifting rope 21. The lifting rope 21 cooperates with the pulling rope 413 to pull the protective plate 1 to move upward synchronously with the staff, and the protective plate 1 always remains in a horizontal state below the staff.

[0027] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, the support portion 521 includes a plurality of groups of limit rods 5211 rotatably installed on the side wall of the balancing cone 3 and distributed relatively to the support rod 4, and the end of the limit rod 5211 away from the balancing cone 3 is provided with a second clamping rod 5212 which cooperates with the support rod 4, and the second clamping rod 5212 is a V-shaped structure, and the adjusting portion 522 is connected to the limit rod 5211, and the adjusting portion 522 is used to adjust the inclination angle of the limit rod 5211 at the side wall of the balancing cone 3.

[0028] The adjusting portion 522 supports and positions the limiting rod 5211 at the outside of the balancing cone 3. When the support rod 4 rotates toward the balancing cone 3, the support rod 4 contacts the second clamping rod 5212, and the limiting rod 5211 and the second clamping rod 5212 cooperate with each other. The support rod 4 can be positioned at the outside of the balancing cone 3. During the climbing process, the support rod 4 is in the inner cavity of the tower crane. The inclination angle of the limiting rod 5211 can be adjusted through the adjusting portion 522, and then the inclination angle of the support rod 4 can be adjusted, which is convenient for use in the inner cavity of tower cranes of different models and sizes.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, as a preferred embodiment of the present invention, the adjusting portion 522 includes a control cavity 5221 opened inside the balancing cone 3, and the side wall of the balancing cone 3 is provided with multiple groups of connecting grooves 5222 distributed in an annular manner and connected to the control cavity 5221, a threaded rod 5223 is rotatably installed in the control cavity 5221, and a control block 5224 is threadedly connected to the surface of the threaded rod 5223, and the control block 5224 is slidably installed in the control cavity 5221, and a push-pull rod 5225 is rotatably installed on the side wall of the control block 5224, and one end of the push-pull rod 5225 away from the control block 5224 extends through the connecting groove 5222 to the outside of the balancing cone 3 and is rotatably connected to the side wall of the limiting rod 5211, and the bottom end of the threaded rod 5223 extends to the outside of the balancing cone 3 and is fixedly installed with a control disk 5226.

[0030] When in use, the handheld control disk 5226 is rotated, and the control disk 5226 drives the threaded rod 5223 to rotate and then pushes the control block 5224 to move in the control cavity 5221. The control block 5224 cooperates with the push-pull rod 5225 to conveniently adjust the inclination angle of the limit rod 5211 on the outside of the balance cone 3. The limit rod 5211 cooperates with the second clamping rod 5212 to synchronously adjust the inclination angle of the support rod 4 on the outside of the configuration function block 3. During the entire climbing process, the protective plate 1 and the support rod 4 are both in the inner cavity of the tower crane and will not interfere with the rods of the tower crane, thereby enabling the equipment to be used in the inner cavity of tower cranes of different models and sizes.

[0031] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, the protective component 53 includes an extrusion spring fixedly installed on the side wall of the balancing cone 3, and the extrusion springs are provided in multiple groups and are distributed in a ring shape with equal spacing around the balancing cone 3, and one end of the extrusion spring away from the balancing cone 3 is in contact with the support rod 4.

[0032] When climbing, the support rod 4 applies a thrust to the extrusion spring. At this time, the extrusion spring is in a compressed state. When the staff member misses a step and falls during climbing, the staff member will release the tension on the lifting rope 21 when falling, and the lifting rope 21 and the pulling rope 513 will simultaneously release the tension on the support rod 4. At this time, the extrusion spring applies a thrust to the support rod 4, and the support rod 4 rotates away from the balance cone 3. At this time, the bottom end of the support rod 4 is inserted to the outside of the rod of the tower crane. When the protective plate 1 falls, the multiple groups of support rods 4 can stably support the protective plate 1, and the staff member will directly fall on the surface of the protective plate 1. The height between the position where the staff member falls and the protective plate 1 is relatively short, and no injury will occur, which can effectively prevent the staff from falling continuously in the inner cavity of the tower crane and causing accidents.

[0033] like Figure 4As shown, as a preferred embodiment of the present invention, a roller 6 cooperating with the pulling rope 513 is rotatably installed in the transverse hole 512 .

[0034] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, the upper half of the balancing cone 3 is an inverted truncated cone structure, and the lower half of the configuration block 3 is a cylindrical structure.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the bottom wall of the balancing cone 3 is provided with multiple groups of positioning screw holes 7 distributed in an annular shape, and the surface of the control disk 5226 is provided with positioning screws 8 that cooperate with the positioning screw holes 7.

[0036] The working principle of the present invention is: when the staff climbs in the inner cavity of the tower crane, they first tie the belt 2 to the tail of the waist. During the climbing process, the staff drives the lifting rope 21 to move upward synchronously. The lifting rope 21 cooperates with the pulling rope 513 to apply tension to the support rod 4 so that the support rod 4 rotates toward the balance cone 3. The support rod 4 is in contact with the second clamping rod 5212, and the limit rod 5211 cooperates with the second clamping rod 5212 to position the support rod 4 on the outside of the balance cone 3. At this time, the support rod 4 and the protective plate 1 form a whole, and the belt 2 and the lifting rope 21 cooperate with each other to suspend the protective plate 1. The protective plate 1 is always under the staff. When climbing, the staff can move upward synchronously with the protective plate 1, and the balance cone 3 controls the protective plate 1 to maintain a horizontal state.

[0037] During the climbing process, the support rod 4 and the first clamping rod 41 are both in the inner cavity of the tower crane, and the support rod 4 and the first clamping rod 41 will not interfere with the rods of the tower crane. During a long period of climbing, the protective plate 1 is always under the staff and moves upward synchronously. When the staff is tired and wants to rest, the staff's feet stand on the rods in the inner cavity of the tower crane, and the staff can pull the lifting rope 21, and the lifting rope 21 drives the protective plate 1 to move upward. The staff first holds the protective plate 1, and then controls the lifting rope 21 to adjust the pulling force of the pulling rope 513 on the support rod 4, which can control the support rod 4. The support rod 4 is rotated a certain distance away from the balance cone 3, so that the first clamping rod 41 is directly above the rod on the surface of the tower crane, and the first clamping rod 41 is clamped on the rod on the surface of the tower crane. Multiple groups of support rods 4 can stably support and position the protective plate 1. At this time, the staff can sit on the surface of the protective plate 1 to rest. After the rest, the staff continues to climb upwards. At this time, the protective plate 1 is suspended by the lifting rope 21, and the lifting rope 21 is in a straightened state. The lifting rope 21 and the pulling rope 513 cooperate with each other to apply tension to the support rod 4. At this time, the support rod 4 rotates to its original position toward the balance cone 3. When an accident occurs during climbing and a worker misses a step and falls, the worker will release the tension on the lifting rope 21 when falling, and the lifting rope 21 and the pulling rope 513 will simultaneously release the tension on the support rod 4. At this time, the extrusion spring applies a thrust to the support rod 4, and the support rod 4 rotates away from the balance cone 3. At this time, the bottom end of the support rod 4 is inserted to the outside of the rod of the tower crane. When the protective plate 1 falls, the multiple groups of support rods 4 can stably support the protective plate 1, and the worker will directly fall on the surface of the protective plate 1. The height between the position where the worker falls and the protective plate 1 is relatively short, and no injury will occur, which can effectively prevent the worker from falling continuously in the inner cavity of the tower crane and causing accidents.

[0038] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
