[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-11 , the present invention provides a technical solution: a tower crane special elevator, including an elevator main body 1, a tower crane standard section 11 is carried above the elevator main body 1, and a driving motor capable of driving the movement of the elevator main body 1 is arranged above the elevator main body 1;

[0033] A fixing mechanism 2, the fixing mechanism 2 is located inside the elevator main body 1, and the fixing mechanism 2 can fix the tower crane standard section 11;

[0034] A clamping mechanism 3, the clamping mechanism 3 is located above the elevator main body 1, and when the fixing mechanism 2 fixes the tower crane standard section 11, the clamping mechanism 3 can clamp the tower crane standard section 11;

[0035] An adjusting member 4, the adjusting member 4 is located inside the elevator main body 1, and after the adjusting member 4 fixes the tower crane standard section 11 through the fixing mechanism 2, it can adjust the driving force of the driving motor according to the size of the tower crane standard section 11 inside the elevator main body 1;

[0036] When the present invention is in use, when the tower crane standard section 11 is pushed into the interior of the elevator main body 1, the tower crane standard section 11 is clamped and fixed by the fixing mechanism 2, and at the same time, the tower crane standard section 11 is clamped by the clamping mechanism 3 to ensure that the tower crane standard section 11 is fixed inside the elevator main body 1. The fixing mechanism 2 cooperates with the clamping mechanism 3 to quickly hold the tower crane standard section 11 tightly, reducing the time for construction workers to fix and disassemble the equipment and improving the overall construction efficiency.

[0037] After the tower crane standard section 11 is fixed by the fixing mechanism 2 each time, the size and specification of the tower crane standard section 11 are determined by the moving distance of the clamping plate 63. At the same time, the adjusting member 4 adjusts the voltage of the driving motor in a variable frequency manner according to the size of the tower crane standard section 11, and automatically adjusts the speed and torque according to the load weight and operating height, ensuring both stable lifting and energy conservation.

[0038] The fixing mechanism 2 includes a pressing plate 21 arranged inside the elevator main body 1. The pressing plate 21 is slidably connected to the elevator main body 1. Both ends of the pressing plate 21 are provided with connecting plates 22. The connecting plates 22 are rotatably connected to the pressing plate 21. One end of the connecting plate 22 away from the pressing plate 21 is rotatably connected to a sliding plate 23. A sliding groove 24 is formed above the sliding plate 23.

[0039] When it is necessary to use the elevator main body 1 to transport the tower crane standard section 11, the tower crane standard section 11 is placed inside the elevator main body 1, and the tower crane standard section 11 is pushed to make the tower crane standard section 11 push the pressing plate 21. The pressing plate 21 drives the sliding plate 23 to slide through the connecting plate 22. At this time, the connecting plates 22 and the sliding plate 23 at both ends slide towards both ends, and at this time, the pressing plate 21 fits against the inner wall of the elevator main body 1.

[0040] A limiting member 5 capable of restricting the sliding of the sliding plate 23 is provided inside the elevator main body 1. The limiting member 5 includes two limiting rods 51 fixedly connected to the inner wall of the elevator main body 1. The limiting rods 51 are located in the sliding groove 24 and are slidably connected to the sliding groove 24. The sliding plate 23 moves parallel to the inner wall of the elevator main body 1. One end of the sliding plate 23 away from the connecting plate 22 is fixedly connected to a sliding ring 52. A reciprocating lead screw 53 is arranged inside the sliding ring 52. The sliding ring 52 is threadedly connected to the reciprocating lead screw 53. The end of the reciprocating lead screw 53 is rotatably connected to the elevator main body 1. A fixing member 6 capable of fixing the tower crane standard section 11 is arranged on the periphery of the reciprocating lead screw 53.

[0041] When the sliding plate 23 slides, since the limiting rod 51 fixedly connected to the inner wall of the elevator main body 1 is located inside the sliding groove 24 formed in the sliding plate 23, at this time, the sliding plate 23 slides along the inner wall of the elevator main body 1. When the sliding plate 23 slides, the sliding ring 52 fixedly connected to the end of the sliding plate 23 slides around the reciprocating lead screw 53. Since the sliding ring 52 is threadedly connected to the reciprocating lead screw 53, and both ends of the reciprocating lead screw 53 are rotatably connected to the elevator main body 1, when the sliding ring 52 slides, the reciprocating lead screw 53 rotates inside the sliding ring 52. When the reciprocating lead screw 53 rotates, it can drive the fixing member 6 to fix the tower crane standard section 11.

[0042] The fixing member 6 includes a fixing ring 61 arranged around the reciprocating lead screw 53. The fixing ring 61 is threadedly connected to the reciprocating lead screw 53. The fixing ring 61 has a reverse thread with the sliding ring 52. The fixing ring 61 is located at one end of the sliding ring 52 close to the pressing plate 21. An extension plate 62 is fixedly connected to the outer wall of the fixing ring 61. A clamping plate 63 is fixedly connected to one end of the extension plate 62 away from the fixing ring 61. The clamping plate 63 is located inside the elevator main body 1 and is slidably connected to the elevator main body 1.

[0043] When the reciprocating lead screw 53 rotates, since the fixing ring 61 is arranged around the reciprocating lead screw 53 and is threadedly connected to the reciprocating lead screw 53, the reciprocating lead screw 53 drives the fixing ring 61 to move. Also, since the fixing ring 61 has a reverse thread with the sliding ring 52, the sliding ring 52 slides towards both ends, and the fixing ring 61 moves towards the center. At this time, the fixing ring 61 drives the clamping plate 63 to slide through the extension plate 62. When the clamping plate 63 slides, since a limiting block 64 is fixedly connected to the bottom of the clamping plate 63, and a limiting groove 65 is formed in the inner wall of the elevator main body 1, the limiting block 64 is located inside the limiting groove 65 and is slidably connected to the limiting groove 65. The limiting block 64 located below the clamping plate 63 sliding inside the limiting groove 65 can ensure the horizontal movement of the clamping plate 63. The two clamping plates 63 moving closer can clamp the tower crane standard section 11, fixing the tower crane standard section 11 inside the elevator main body 1, and can accurately adapt to tower crane standard sections 11 of different specifications, ensuring a stable connection during the operation of the elevator. The installation time can be greatly shortened compared with the traditional method.

[0044] The clamping mechanism 3 includes a rope 31 fixedly connected to the outer wall of the clamping plate 63. The outer wall of the elevator main body 1 is fixedly connected with a conduit 32. The rope 31 is located inside the conduit 32 and is slidably connected to the conduit 32. One end of the conduit 32 away from the clamping plate 63 is located above the elevator main body 1. Above the elevator main body 1, there is a clamping member 7 capable of clamping the tower crane standard section 11. The clamping member 7 includes a support rod 71 fixedly connected to the upper end of the elevator main body 1. The support rod 71 is located above the conduit 32. A torsion spring 72 is fixedly connected to the outer wall of the support rod 71. One end of the torsion spring 72 away from the support rod 71 is fixedly connected with a winch 73. The winch 73 is located around the support rod 71 and is rotatably connected to the support rod 71. One end of the rope 31 away from the clamping plate 63 is wound around the periphery of the winch 73. A clamping rod 74 is fixedly connected to the outer wall of the winch 73. The clamping rod 74 is rotatably connected to the elevator main body 1;

[0045] When the clamping plates 63 at both ends approach each other, the clamping plates 63 drive the rope 31 to slide inside the conduit 32. One end of the rope 31 away from the clamping plate 63 drives the winch 73 to rotate. At this time, the winch 73 drives the torsion spring 72 to store energy. At the same time, the winch 73 drives the clamping rod 74 to rotate around the elevator main body 1. When the clamping rod 74 rotates, it can abut against the upper end of the tower crane standard section 11 to clamp and fix the tower crane standard section 11. The clamping rod 74 cooperates with the clamping plate 63 to ensure that the tower crane standard section 11 shakes, effectively reducing the shaking amplitude during operation and greatly improving the safety of material transportation.

[0046] A handle 75 is fixedly connected to the end of the clamping rod 74. A limiting plate 76 is fixedly connected to the outer wall of the elevator main body 1. One end of the limiting plate 76 abuts against the clamping rod 74. When it is necessary to remove the tower crane standard section 11, pull the handle 75. At this time, the handle 75 drives the clamping rod 74 to rotate in the reverse direction. The clamping rod 74 drives the winch 73 to rotate in the reverse direction. At this time, the rope 31 pulls the clamping plate 63 to move towards both ends. The reverse movement of the clamping plate 63 can drive the sliding plate 23 to move in the reverse direction through the reciprocating lead screw 53, which will not be elaborated here. The extrusion plate 21 returns to its original position to eject the tower crane standard section 11. Quick disassembly and assembly can improve the efficiency of material transportation.

[0047] The adjusting member 4 includes an adjusting plate 41 fixedly connected to the outer wall of the elevator main body 1. A resistance wire 42 is fixedly connected inside the adjusting plate 41. An electrode rod 43 is fixedly connected to the outer wall of the fixing ring 61. The electrode rod 43 is located at one end of the fixing ring 61 away from the extension plate 62. The electrode rod 43 is in close contact with the resistance wire 42. The electrode rod 43 and the resistance wire 42 are respectively connected to the driving motor circuit;

[0048] When the fixed ring 61 slides around the reciprocating lead screw 53, the electrode rod 43 at one end of the fixed ring 61 slides closely along the resistance wire 42. Since the electrode rod 43 and the resistance wire 42 are respectively connected to the driving motor circuit (the driving motor is not shown in the figure), when the tower crane standard section 11 inside the elevator main body 1 is larger, the moving distance of the clamping plate 63 is closer. Similarly, the moving distance of the fixed ring 61 is closer. At this time, the fixed ring 61 drives the electrode rod 43 to slide on the outer wall of the resistance wire 42, so that the effective resistance length of the electrode rod 43 and the resistance wire 42 becomes shorter and the resistance decreases. At this time, the driving torque of the driving motor is larger, which is convenient for lifting the larger and heavier tower crane standard section 11. On the contrary, similarly, for the larger tower crane standard section 11, the driving torque of the driving motor can be reduced, which is an energy-saving design and can reduce the frequency of equipment failure maintenance, effectively saving the construction cost and creating greater economic benefits for the construction project.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
