Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-11 The present invention provides a technical solution: a special tower crane elevator, comprising an elevator body 1, a tower crane standard section 11 is carried on the elevator body 1, and a driving motor capable of driving the elevator body 1 to move is arranged above the elevator body 1; A fixing mechanism 2, the fixing mechanism 2 is located inside the elevator body 1, and the fixing mechanism 2 can fix the tower crane standard section 11; The clamping mechanism 3 is located above the elevator body 1. When the fixing mechanism 2 fixes the tower crane standard section 11, the clamping mechanism 3 can clamp the tower crane standard section 11; The adjusting member 4 is located inside the elevator body 1. After the adjusting member 4 fixes the tower crane standard section 11 through the fixing mechanism 2, the driving force of the driving motor can be adjusted according to the size of the tower crane standard section 11 inside the elevator body 1; When the present invention is in use, when the tower crane standard section 11 is pushed into the interior of the elevator body 1, the tower crane standard section 11 is clamped and fixed by the fixing mechanism 2, and the tower crane standard section 11 is clamped by the clamping mechanism 3 at the same time, ensuring that the tower crane standard section 11 is fixed inside the elevator body 1. The tower crane standard section 11 is quickly clamped by the fixing mechanism 2 and the clamping mechanism 3, which reduces the time for construction personnel to fix and disassemble equipment, thereby improving the overall construction efficiency; Each time the tower crane standard section 11 is fixed by the fixing mechanism 2, the size and specification of the tower crane standard section 11 will be determined by the moving distance of the clamping plate 63. At the same time, the adjusting part 4 performs frequency conversion adjustment on the voltage of the driving motor 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, which can ensure smooth lifting and lowering and save energy.

[0018] The fixing mechanism 2 includes an extrusion plate 21 disposed inside the lift body 1, the extrusion plate 21 is slidably connected to the lift body 1, and connecting plates 22 are disposed at both ends of the extrusion plate 21, the connecting plate 22 is rotatably connected to the extrusion plate 21, and one end of the connecting plate 22 away from the extrusion plate 21 is rotatably connected to a sliding plate 23, and a sliding groove 24 is provided above the sliding plate 23; When the elevator body 1 is needed to transport the tower crane standard section 11, the tower crane standard section 11 is placed inside the elevator body 1, and the tower crane standard section 11 is pushed, so that the tower crane standard section 11 pushes the extrusion plate 21, and the extrusion plate 21 drives the sliding plate 23 to slide through the connecting plate 22. At this time, the connecting plates 22 and the sliding plates 23 at both ends slide toward both ends, and at this time, the extrusion plate 21 is attached to the inner wall of the elevator body 1; A limiter 5 capable of limiting the sliding of the sliding plate 23 is provided inside the lift body 1. The limiter 5 includes two limiter rods 51 fixedly connected to the inner wall of the lift body 1. The limiter rods 51 are located in the sliding grooves 24 and are slidably connected to the sliding grooves 24. The sliding plate 23 moves parallel to the inner wall of the lift body 1. The sliding plate 23 is fixedly connected to a sliding ring 52 at one end away from the connecting plate 22. A reciprocating screw rod 53 is provided inside the sliding ring 52. The sliding ring 52 is threadedly connected to the reciprocating screw rod 53. The end of the reciprocating screw rod 53 is rotatably connected to the lift body 1. A fixing member 6 capable of fixing the tower crane standard section 11 is provided on the periphery of the reciprocating screw rod 53. When the sliding plate 23 slides, since the limit rod 51 fixedly connected to the inner wall of the elevator body 1 is located inside the sliding groove 24 opened in the sliding plate 23, the sliding plate 23 slides along the inner wall of the elevator body 1 at this time. When the sliding plate 23 slides, the sliding ring 52 fixedly connected at the end of the sliding plate 23 slides around the reciprocating screw rod 53. Since the sliding ring 52 is threadedly connected to the reciprocating screw rod 53, and the two ends of the reciprocating screw rod 53 are rotatably connected to the elevator body 1, when the sliding ring 52 slides, the reciprocating screw rod 53 is located inside the sliding ring 52 and rotates. When the reciprocating screw rod 53 rotates, it can drive the fixing part 6 to fix the tower crane standard section 11.

[0019] The fixing member 6 includes a fixing ring 61 disposed on the periphery of the reciprocating screw rod 53, the fixing ring 61 is threadedly connected to the reciprocating screw rod 53, the fixing ring 61 and the sliding ring 52 have opposite threads, the fixing ring 61 is located at one end of the sliding ring 52 close to the extrusion plate 21, an extension plate 62 is fixedly connected to the outer wall of the fixing ring 61, and a clamping plate 63 is fixedly connected to one end of the extension plate 62 away from the fixing ring 61, and the clamping plate 63 is located inside the lift body 1 and is slidably connected to the lift body 1; When the reciprocating screw 53 rotates, since the fixed ring 61 is located at the periphery of the reciprocating screw 53 and is threadedly connected to the reciprocating screw 53, the reciprocating screw 53 drives the fixed ring 61 to move, and since the fixed ring 61 and the sliding ring 52 have opposite threads, the sliding ring 52 slides toward both ends, and the fixed ring 61 moves toward the center. At this time, the fixed ring 61 drives the clamping plate 63 to slide through the extension plate 62. When the clamping plate 63 slides, since the bottom of the clamping plate 63 is fixedly connected to the limiting block 64, the inner wall of the elevator body 1 is provided with a limiting block Slot 65, the limit block 64 is located inside the limit slot 65 and is slidably connected to the limit slot 65, the limit block 64 located below the clamping plate 63 is located inside the limit slot 65 and slides to ensure the horizontal movement of the clamping plate 63, and the clamping plates 63 at both ends are close together to clamp the tower crane standard section 11, so that the tower crane standard section 11 is fixed inside the elevator body 1, and can accurately adapt to tower crane standard sections 11 of different specifications, ensuring the stable connection of the elevator during operation, and the installation time can be greatly shortened compared with the traditional method.

[0020] The clamping mechanism 3 includes a rope 31 fixedly connected to the outer wall of the clamping plate 63, a conduit 32 fixedly connected to the outer wall of the lift body 1, the rope 31 is located inside the conduit 32 and is slidably connected to the conduit 32, the end of the conduit 32 away from the clamping plate 63 is located above the lift body 1, and a clamping member 7 capable of clamping the tower crane standard section 11 is provided above the lift body 1, the clamping member 7 includes a support rod 71 fixedly connected to the upper end of the lift 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, and a capstan 73 is fixedly connected to the end of the torsion spring 72 away from the support rod 71, the capstan 73 is located outside the support rod 71 and is rotatably connected to the support rod 71, the end of the rope 31 away from the clamping plate 63 is wound around the periphery of the capstan 73, a clamping rod 74 is fixedly connected to the outer wall of the capstan 73, and the clamping rod 74 is rotatably connected to the lift body 1; When the two end clamps 63 are close to each other, the clamps 63 drive the rope 31 to slide inside the guide tube 32, and the end of the rope 31 away from the clamps 63 drives the winch 73 to rotate. At this time, the winch 73 drives the torsion spring 72 to store force. At the same time, the winch 73 drives the clamping rod 74 to rotate around the elevator 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 clamps 63 to ensure that the tower crane standard section 11 can swing, effectively reducing the swing amplitude during operation and greatly improving the safety of material transportation.

[0021] A handle 75 is fixedly connected to the end of the clamping rod 74, and a limit plate 76 is fixedly connected to the outer wall of the lifting body 1. One end of the limit plate 76 abuts against the clamping rod 74. When the tower crane standard section 11 needs to be removed, the handle 75 is pulled. At this time, the handle 75 drives the clamping rod 74 to rotate in the opposite direction, and the clamping rod 74 drives the winch 73 to rotate in the opposite direction. At this time, the rope 31 pulls the splint 63 to move toward both ends. The reverse movement of the splint 63 can drive the sliding plate 23 to move in the opposite direction through the reciprocating screw rod 53. It will not be repeated here. The resetting of the extrusion plate 21 can pop out the tower crane standard section 11, and quick disassembly and assembly can improve material transportation efficiency.

[0022] The adjusting member 4 includes an adjusting plate 41 fixedly connected to the outer wall of the elevator 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 the end of the fixing ring 61 away from the extension plate 62, the electrode rod 43 is close to the resistance wire 42, and the electrode rod 43 and the resistance wire 42 are respectively connected to the driving motor circuit; When the fixed ring 61 slides around the reciprocating screw rod 53, the electrode rod 43 located at one end of the fixed ring 61 slides close to the resistance wire 42. Since the electrode rod 43 and the resistance wire 42 are respectively connected to the drive motor circuit, the drive motor is not shown in the figure. When the tower crane standard section 11 located inside the elevator body 1 is larger, the clamping plate 63 moves a shorter distance. Similarly, the fixed ring 61 moves a shorter distance. 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 is reduced. At this time, the driving torque of the drive motor is larger, which is convenient for lifting larger and heavier tower crane standard sections 11. Conversely, for larger tower crane standard sections 11, the driving motor torque can be reduced. Energy-saving design and reduced frequency of equipment failure maintenance can effectively save construction costs and create greater economic benefits for construction projects.
