Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a hoisting device for a prefabricated building construction machine with auxiliary balancing function. Background Technology

[0002] A building construction machine is a piece of equipment or technical system used for the rapid construction of high-rise buildings. Primarily used in the structural construction of high-rise buildings, it improves construction efficiency and safety through mechanization and automation, while reducing labor costs. In modern construction, building construction machines have become a crucial piece of equipment for improving construction efficiency and are an important symbol of the industrialization and intelligent development of the construction industry. During the construction of high-rise prefabricated buildings, various prefabricated components need to be hoisted into the building construction machine for assembly. Currently, tower cranes are mainly used on top of the machine to hoist these components. However, the tower cranes themselves are quite tall, making the assembly and disassembly processes on the upper part of the building cumbersome. After the prefabricated components are hoisted to the assembly position, they are often in an unstable state, requiring repeated communication and coordination between assembly and construction personnel to ensure smooth assembly. This places high demands on the skill level of the construction personnel, which is not conducive to ensuring high-precision and high-efficiency assembly. Furthermore, during the lateral movement of the prefabricated components hoisted by the tower crane, wind resistance and the crane's own inertia (especially for prefabricated wall panels) can cause the components to sway. Improper operation can lead to violent shaking, posing a safety hazard and requiring improvement. Utility Model Content

Detailed Implementation

[0025] Example 1, see appendix Figure 1-8 A hoisting device for a prefabricated building construction machine 1 with auxiliary balancing function includes a traveling mechanism installed between two parallel supporting main beams 3. The two supporting main beams 3 are fixedly installed on both sides of the upper end of the building construction machine 1. Several raised frames 6 are evenly arranged between the supporting main beams 3 and the building construction machine 1. The raised frames 6 support the supporting main beams 3 to a certain height, providing space for the prefabricated components to be hoisted and moved laterally, ensuring that the prefabricated components can be hoisted and moved freely on the upper part of the building body 2.

[0026] The upper surface of the supporting main beam 3 is provided with a longitudinal track 31 along its length. The main body of the traveling mechanism is a square shell-shaped main frame 4. Two track wheels 41 are arranged side by side at both ends of the main frame 4. The track wheels 41 at both ends are matched and connected to the longitudinal track 31 on both sides. The main frame 4 can move along the longitudinal track 31 through the track wheels 41. The main frame 4 is provided with a longitudinal drive assembly connected to the track wheels 41. The longitudinal drive assembly drives the track wheels 41 to rotate. The bottom surface of the main frame 4 is provided with an I-beam 42. A winch 5 is provided below the I-beam 42. The winch 5 is slidably connected to the I-beam 42 through a sliding bracket 51. The winch 5 slides along the I-beam 42 under the action of the sliding bracket 51. A transverse drive assembly is provided between the winch 5 and the I-beam 42. The transverse drive assembly provides power to the sliding bracket 51, driving the sliding bracket 51 and the winch 5 to move along the I-beam 42.

[0027] Two clamping and positioning mechanisms 7 are symmetrically fixedly installed on the housings on both sides of the winch 5. The hook 56 of the winch 5 is located between the two clamping and positioning mechanisms 7. The clamping and positioning mechanism 7 includes a lead screw motor 71, two symmetrically arranged L-shaped upper connecting rods 72, and two symmetrically arranged jaws 73. The lead screw motor 71 is fixedly installed inside the docking frame 74. A lower support 76 is fixedly connected to the lower end of the docking frame 74 through a vertical support column 75. Two lower connecting rods 77 are symmetrically hinged on both sides of the lower support 76. The upper ends of the two jaws 73 are hinged to the outer ends of the two lower connecting rods 77. The jaws 73 are connected to the lower support 76 through the lower connecting rods 77. The working space of the gripper 73 is increased, thereby increasing the clamping range of the two grippers 73 and increasing the clamping force on the precast component. The lower ends of the two L-shaped upper connecting rods 72 are respectively hinged to the upper ends of the two grippers 73. The lower part of the L-shaped upper connecting rod 72 has a U-shaped structure, which can improve its stability when hinged to the upper end of the gripper 73. A lead screw 711 is connected to the output shaft of the lead screw motor 71. The lower end of the lead screw 711 is rotatably connected to the lower support 76. A nut sleeve 78 is connected to the lead screw 711. A transverse drive rod 79 is fixedly installed on the nut sleeve 78. The two ends of the transverse drive rod 79 are respectively hinged to the upper ends of the two L-shaped upper connecting rods 72.

[0028] The working principle of the clamping and positioning mechanism 7 is as follows: the lead screw motor 71 drives the lead screw 711 to rotate, the lead screw 711 drives the nut sleeve 78 to move up and down through the thread, the nut sleeve 78 pulls the L-shaped upper connecting rods 72 on both sides through the drive rod, the two L-shaped upper connecting rods 72 push and pull the two lower jaws 73 at the same time, and the two jaws 73 move synchronously towards each other or in opposite directions under the action of the lower connecting rod 77 to achieve clamping or loosening action.

[0029] The inner side of the gripper 73 is provided with a rubber block 791, and the inner side of the rubber block 791 is provided with an anti-slip texture 792. The friction between the gripper 73 and the precast component is increased by the rubber block 791 and the anti-slip texture 792, so as to ensure the firmness of the gripper on the precast component.

[0030] When the device is working, the longitudinal drive assembly drives the I-beam 42 and the winch 5 to move synchronously along the longitudinal track 31. When the winch 5 moves to the outside of the building body 2, the winch 5 is started to lower the hook 56 to the ground. The hook 56 is engaged with the lifting lug on the precast component. The winch 5 rotates in the opposite direction to lift the precast component. When the precast component reaches the top of the building machine 1 and is ready to be moved laterally to the top of the building body, the two clamping and positioning mechanisms 7 are started simultaneously. The jaws 73 at the lower end of the two clamping and positioning mechanisms 7 close synchronously and clamp the upper part of the precast wall panel 8, which plays an auxiliary positioning role. Then, the combination of the longitudinal drive assembly and the transverse drive assembly is used to adjust the position of the precast component along the track, which can effectively improve the stability of the precast component during the transverse movement and avoid violent shaking. It has the advantages of simple and convenient hoisting operation. Operators can use this device to perform assembly work with high quality and high efficiency.

[0031] Example 2, see appendix Figure 3-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the longitudinal drive assembly includes a first reduction motor and a main shaft 43 disposed inside the main frame 4. The first reduction motor is fixedly mounted on the bottom plate of the main frame 4. A first gear 44 is provided on the shaft of the first reduction motor. The main shaft 43 is rotatably connected between the two end plates of the main frame 4 and is located in the middle of the main frame 4. A second gear 45 that meshes with the first gear 44 is provided in the middle of the main shaft 43. Both ends of the main shaft 43 are provided with drive wheels. The drive wheels are in contact with the circumferential sides of the two adjacent track wheels 41. The drive wheel is a third gear 46. A gear ring 411 is coaxially provided at the inner end of the track wheel 41. The size of the gear is smaller than the size of the gear ring 411. The third gear 46 meshes with the gear ring 411.

[0032] When the longitudinal drive assembly of this embodiment is working, the first reduction motor is started to drive the second gear 45 to rotate. The second gear 45 drives the first gear 44 and the main shaft 43 to rotate. The two third gears 46 at both ends of the main shaft 43 rotate accordingly. The third gears drive the two track wheels 41 to rotate synchronously by meshing with the gear rings 411 on both sides, thereby realizing the synchronous drive of the four track wheels 41 on the main frame 4. The main frame 4 moves along the tracks on both sides, and the winch 5 below moves longitudinally on the top of the building machine 1 to lift the prefabricated components. At the same time, a synchronous shaft 47 is connected between the corresponding track wheels 41 at both ends of the main frame 4. The synchronous shaft ensures that the track wheels 41 on both sides rotate synchronously, thereby improving the stability of the main frame 4 moving along the longitudinal track 31 and avoiding the phenomenon of the main frame 4 deviating from the track due to the different speeds of the track wheels 41 on both sides.

[0033] Example 3, see appendix Figure 2 , 4 -7. This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the lower part of both sides of the I-beam 42 is provided with transverse rails 421, and the upper part of the sliding bracket 51 is provided with guide wheels 52 on both sides. The guide wheels have a certain taper. The guide wheels 52 on both sides are matched and connected to the two transverse rails 421. The transverse rails 421 are set as inclined rails according to the taper of the guide wheels 52. The winch 5 is suspended below the I-beam 42 by the guide wheels 52 on the sliding bracket 51. The transverse drive assembly includes a second reduction motor 53 set on the upper part of the winch 5 and a rack 54 set on the bottom surface of the I-beam 42. A fourth gear 55 is provided on the shaft of the second reduction motor 53, and the fourth gear meshes with the rack.

[0034] When the lateral drive group of this embodiment is working, the second reduction motor 53 is started to drive the fourth gear 55 to rotate. The fourth gear 55 moves along the length direction of the rack 54, thereby moving the winch 5 below along the lateral track 421 to adjust the lateral position of the prefabricated component.
