Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a hoisting transfer device. Background Art

[0002] The tunnel boring machine is a new type of tunnel boring machine developed based on the principle of insects digging holes. Compared with the shield machine: it is small in size and light in weight. It can move forward and backward in the tunnel, has flexible steering, and can dig in any direction, up and down, left and right. It is very convenient to repair faults during tunneling, replace drilling tools, or deal with dangerous geological conditions ahead. After the tunnel excavation support is completed, the tunnel boring machine can be withdrawn along the original route; before using the tunnel boring machine, due to its large size, a hoisting device is required for transportation. At this time, a hoisting and transportation device will be used. The hoisting and transportation device is a device used to transport and transport heavy equipment or machinery. It usually consists of motors, chains or ropes, hooks, brackets and other components. When working, the motor provides power to wind or unwind the chain or rope, thereby controlling the up and down movement of the hook. The hook is fixed to the equipment or machinery to be transported through the bracket, and then it is lifted or lowered by the drive of the motor to realize the transportation operation. The design and specifications of the lifting and transporting device vary according to the weight and size of the objects to be transported. It can be used to lift and transport various types of equipment, including but not limited to tunnel boring machines, cranes, construction materials, etc.

[0003] After searching, the Chinese patent with the announcement number: CN106494994A discloses a hoisting and transferring device. The patent records a buffer device of the hoisting and transferring work platform. When the hoisting and transferring work platform is lowered, the buffer device will play a buffering role to prevent the bottom of the hoisting and transferring work platform from strongly colliding with the ground, effectively protecting the workpiece on the hoisting and transferring work platform as well as the hoisting and transferring work platform itself and the bottom surface technical solution;

[0004] In this solution, the staff carries the transported objects by using the bottom plate, the retaining wall and the retaining chain. Meanwhile, the space they carry is limited. When transporting different transported objects, there will be problems such as being unable to carry the load and shaking due to the increased space. The tunnel boring machine equipment is heavy, and the device cannot effectively fix the tunnel boring machine during transportation, thereby greatly reducing the work efficiency. In order to solve this technical problem, the utility model proposes a hoisting and transporting device. Summary of the invention

[0024] Embodiment 1: A lifting and transporting device comprises a vehicle body 1 and a top plate 13, a connecting block 16 is slidably connected to the inside of the top plate 13, and a slider 18 is slidably connected to the top of the top plate 13, two sets of connecting plates 2 are fixedly connected to the outer wall of the vehicle body 1, and a support rod 3 is fixedly connected to the other end of the connecting plate 2, a bracket 4 is fixedly connected to the top of the vehicle body 1, a motor 5 is fixedly connected to the top of the bracket 4, and a rotating column 6 is fixedly connected to the output end of the motor 5, and the rotating column 6 is rotatably connected to the bracket 4, a cross bar 7 is fixedly connected to the outer wall of the rotating column 6, and a chain electric hoist 8 is fixedly connected to the other end of the cross bar 7, and a hook 9 is fixedly connected to the output end of the chain electric hoist 8, and a chain frame 10 is arranged inside the hook 9, and the two ends of the chain frame 10 are rotatably connected to the inner rod 12, and the two ends of the top of the top plate 13 are fixedly connected to the fixing frame 11, and the inner rod 12 is fixedly connected to the fixing frame 11 Inside the fixed frame 11, one side of the top plate 13 is fixedly connected to a motor 2 14, and the output end of the motor 2 14 is fixedly connected to a bidirectional threaded rod 15, and the bidirectional threaded rod 15 is rotatably connected to the inside of the top plate 13. At the same time, the outer walls at both ends of the top plate 13 are threadedly connected to connecting blocks 16, and both sides of the connecting blocks 16 are fixedly connected to sliders 18. Fixed plates 19 are fixedly connected to the top two ends of the top plate 13, and a pair of fixed rods 17 are fixedly connected between the fixed plates 19 on both sides. At the same time, the fixed rods 17 correspond to the sliders 18, and the sliders 18 are slidably connected to the outer walls of the fixed rods 17, and chains 20 are fixedly connected to the bottom walls of the connecting blocks 16 on both sides, and the outer walls of the other ends of the chains 20 are fixedly connected to an upper pressure plate 21, and the upper pressure plate 21 is threadedly connected to a threaded column 22, and the other end of the threaded column 22 is fixedly connected to an anti-slip plate 23, and the bottom end of the chain 20 is fixedly connected to a bottom plate 24.

[0025] The equipment is supported by the vehicle body 1 and supported and fixed by the support rods 3 on the four-corner connecting plates 2. The motor 1 5 is started, which drives the rotating column 6 to rotate, thereby rotating the crossbar 7 at a fixed point, and adjusting the top plate 13 until the tunnel boring machine is directly above. Then, the chain electric hoist 8 is started, which releases the hook 9 and moves the top plate 13 on the chain frame 10 downward. When it moves to the outer wall of the tunnel boring machine, the motor 2 14 is started, which drives the bidirectional threaded rod 15 to rotate, thereby driving the connecting block 16 to move back and forth.

When the bottom plate 24 fits the bottom of the tunnel boring machine, the threaded column 22 on the upper pressure plate 21 is rotated to drive the anti-slip plate 23 to move downward until it is completely matched with the clamping plates on both sides of the tunnel boring machine and fixed.

When it moves to the outer wall of the tunnel boring machine, start the motor 2 14, and the motor 2 14 drives the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 will drive the connecting blocks 16 at both ends to move back and forth. The sliders 18 on both sides are limited on the fixed rod 17 to prevent deviation during movement. When the connecting block 16 moves, the bottom plate 24 on the chain 20 will be driven to move. When it moves to fit with the clamping plates on both sides of the tunnel boring machine, the bottom plate 24 is fitted to the bottom of the tunnel boring machine. At this time, the threaded column 22 on the upper pressure plate 21 is rotated, and the anti-slip plate 23 is driven to move downward under the rotation of the threaded column 22 until it moves to fit with the clamping plates on both sides of the tunnel boring machine and is firmly stuck. After the fixation is completed, the chain electric hoist 8 is started in reverse, the top plate 13 is driven upward through the chain frame 10, and the tunnel boring machine is driven to rise and then transported by starting the motor 5. Through the cooperation between them, the work efficiency is greatly improved.
