Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to an integrated prefabricated building construction machine lifting and transportation device. Background Technology

[0002] Building construction machines are characterized by their wide applicability, high load-bearing capacity, and multi-level fall protection. They are fully enclosed operating spaces integrating safety, canopy, and maintenance systems. Building construction machines can significantly increase construction speed; some can complete a floor in as little as 3 or 4 days, far exceeding the speed of traditional scaffolding construction. The fully enclosed operating space effectively isolates potential hazards on the construction site, providing workers with a safer working environment. In 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 to hoist prefabricated components from the top of the machine. However, the large height of the tower cranes makes assembly and disassembly on the upper part of the building cumbersome and carries a high risk. Furthermore, tower cranes have poor stability when hoisting prefabricated components; when the components reach the assembly position, they are often unstable, requiring repeated communication and coordination between assembly and construction personnel to ensure smooth assembly. This places high demands on the skill level of construction workers and is not conducive to ensuring high-precision and high-efficiency assembly, requiring improvement. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an integrated prefabricated building construction machine lifting and transportation device.

[0004] The technical solution of this utility model is: an integrated prefabricated building construction machine lifting and transportation device, including a traveling mechanism installed between two parallel supporting main beams. The two supporting main beams are fixedly installed on the two sides of the upper end of the building construction machine. Both supporting main beams are high-strength I-beams. The upper surface of the supporting main beams is provided with longitudinal rails along their length. The main body of the traveling mechanism is a square shell-shaped main frame. Two track wheels are provided side by side at both ends of the main frame. The track wheels at both ends are matched and connected to the longitudinal rails on both sides. The circumferential side of the track wheel is provided with an annular groove along the circumferential direction to ensure the stability of the track wheel's movement. The main frame is provided with a longitudinal drive component connected to the track wheels. The bottom surface of the main frame is provided with an I-beam. A winch is provided below the I-beam. The winch is provided with a protective shell. The winch is slidably connected to the I-beam through a sliding bracket. The sliding bracket is welded and fixed to the winch's frame. A transverse drive component is provided between the winch and the I-beam.

[0005] Preferably, the longitudinal drive assembly includes a first geared motor and a main shaft disposed inside the main frame. The first geared motor is fixedly mounted on the base plate of the support frame. A first gear is provided on the shaft of the first geared motor. The main shaft is rotatably connected between the two end plates of the main frame through a bearing seat. A second gear that meshes with the first gear is provided in the middle of the main shaft. Both ends of the main shaft are provided with drive wheels. The size of the drive wheels is smaller than that of the track wheels. The drive wheels are in contact with the circumferential sides of the two adjacent track wheels.

[0006] Preferably, the drive wheel is a third gear, and a gear ring is coaxially provided at the inner end of the track wheel. The third gear meshes with the gear ring, and the size of the gear ring is larger than the size of the third gear.

[0007] Preferably, a synchronous shaft is connected between the corresponding track wheels at both ends of the main frame.

[0008] Preferably, the lower part of both sides of the I-beam is provided with transverse rails, the transverse rails on both sides are arranged symmetrically, and the upper part of the sliding bracket is provided with guide wheels on both sides, with at least two guide wheels on each side arranged side by side, and the guide wheels on both sides are matched and connected to the two transverse rails.

[0009] Preferably, the lateral drive assembly includes a second reduction motor disposed on the upper part of the winch and a rack disposed on the bottom surface of the I-beam, the rack extending to both ends of the I-beam, and a fourth gear disposed on the shaft of the second reduction motor, the fourth gear meshing with the rack.

[0010] Preferably, a number of raised support frames are evenly provided between the main supporting beam and the building machine.

[0011] The beneficial technical effects of this utility model are:

[0012] Installed on top of the building construction machine, the winch, driven by the longitudinal and transverse drive components and the longitudinal and transverse rails, can move to the outside of the building structure to hoist prefabricated components onto the upper part of the building construction machine. It can also drive the prefabricated components to adjust their position along the rails, offering the advantages of simple and convenient hoisting operation. Operators can perform assembly work with high quality and efficiency using this device. Furthermore, this device solves the problem of poor hoisting stability caused by the large height of tower cranes, thus improving the safety of prefabricated component hoisting.

[0020] Example 1, see appendix Figure 1-3 An integrated prefabricated building construction machine hoisting and transportation device 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.

[0021] 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. The track wheels 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 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.

[0022] 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, 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. It has the advantages of simple and convenient hoisting operation. Operators can perform assembly operations with high quality and high efficiency through this device.

[0023] Example 2, see appendix Figure 3-4 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.

[0024] 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 46 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, carrying the winch 5 below to move longitudinally on the top of the building machine 1 to lift 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 47 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.

[0025] Example 3, see appendix Figure 3-46. This embodiment is basically the same as embodiment one, 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 55 meshes with the rack 54.

[0026] 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.
