Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated shafts, in particular to a prefabricated shaft unloading device. Background Art

[0002] Existing pipeline laying usually involves docking multiple groups of prefabricated shafts and then laying them into the soil layer. Prefabricated shafts are usually made of cast concrete. Before laying, the prepared prefabricated shafts need to be transported to the laying site. The bumps generated during transportation can easily cause cracks on the surface of the prefabricated shafts, thereby causing damage to the prefabricated shafts. This requires the use of a prefabricated shaft unloading device.

[0003] Patent document CN219708889U discloses a prefabricated shaft unloading device, "including a mounting frame, a clamping member, rollers and a mounting assembly, etc., wherein a left-right symmetrical clamping member is slidably connected to the middle of the mounting frame, and a plurality of rollers are connected to the mounting frame and the clamping member, and a mounting assembly is connected to the upper middle side of the mounting frame. The utility model enables the prefabricated shaft to be surrounded and clamped by the clamping member and the mounting frame through the cooperation between the clamping member and the mounting frame, thereby enabling the crane to lift the prefabricated shaft by lifting the mounting frame to prevent the prefabricated shaft from tipping over, and supports the bottom of the prefabricated shaft by the bottom supporting member, so that the prefabricated shaft can be stably placed during unloading."

[0004] The above-mentioned equipment supports the bottom of the prefabricated shaft through the supporting parts, so that the prefabricated shaft can be stably placed during unloading. Since the prefabricated shaft is made of cast concrete, cracks are easily generated after being vibrated, which may cause damage to the prefabricated shaft. When the prefabricated shaft is transported, it is difficult for the equipment to cushion the vibration, which may easily cause damage to the prefabricated shaft. This requires staff to improve their equipment. Utility Model Content

[0027] Before using the equipment to load and transport the prefabricated shaft, first rotate and open the first protective plate 1 and the second protective plate 2, then hoist the two groups of prefabricated shafts to the top of the two groups of arc plates 5 respectively through the hoisting equipment, and then rotate the first protective plate 1 and the second protective plate 2 to close them. After the first protective plate 1 and the second protective plate 2 are closed, the prefabricated shaft is wrapped in the middle. When the equipment is vibrated during transportation, the first spring 6 and the damper 4 are used in combination to form a buffer between the arc plate 5 and the support plate 3, thereby buffering the prefabricated shaft on the top of the arc plate 5.

[0028] See also Figure 1 A prefabricated wellbore unloading device: the inner walls of one side of the first protective plate 1 and the second protective plate 2 are fixedly connected with a fixed plate 7, a universal wheel 8 is provided at the bottom of the fixed plate 7, and triangular support blocks 9 are fixedly connected to both sides of the top of the fixed plate 7, and one side of the triangular support block 9 is fixedly connected to the bottom of one side of the first protective plate 1.

[0029] After loading the prefabricated shaft, the staff can move it through the universal wheels 8 at the bottom of the fixed plate 7.

The movement of the first protective plate 1 and the second protective plate 2 drives the internal prefabricated shaft to move and transport. The triangular support block 9 can reinforce the fixed plate 7 and the first protective plate 1 and the second protective plate 2.

[0031] Before loading the prefabricated shaft, first pull the handle 13 to remove the latch 12 from the slot 11, thereby rotating the first protective plate 1 and the second protective plate 2 open. After loading the prefabricated shaft, rotate the first protective plate 1 and the second protective plate 2 closed, so that the block 10 on one side of the second protective plate 2 is inserted into the slot 20 on one side of the first protective plate 1, and then release the handle 13 to reset the second spring 14. The reset of the second spring 14 pushes the limit plate 15 to move. After the limit plate 15 moves, it drives the latch 12 to reset. After the latch 12 is reset, it is inserted into the slot 11, thereby fixing the first protective plate 1 and the second protective plate 2.

A hand wheel 18 is threadedly connected to one side of the inner wall of the telescopic plate 17. A threaded groove 19 is opened on the top of the first protective plate 1, and the bottom of the hand wheel 18 is threadedly connected to the inner wall of the threaded groove 19.

[0033] After the prefabricated wellbore is loaded, the telescopic plate 17 is rotated to overlap the side of the telescopic plate 17 with the handwheel 18 to the top of the threaded groove 19. The handwheel 18 is rotated to fix the handwheel 18 to the top of the threaded groove 19, thereby fixing one end of the telescopic plate 17 to the top of the first protective plate 1.

[0034] Working principle: before using the equipment to load the prefabricated shaft, first take out the pin 12 from the slot 11, then rotate the first protective plate 1 and the second protective plate 2, and after the two groups are opened, hoist the prefabricated shaft to the top of the arc plate 5, then close the first protective plate 1 and the second protective plate 2, and insert the pin 12 into the slot 11 to fix the first protective plate 1 and the second protective plate 2. The staff can push the equipment for transportation through the universal wheel 8. When the equipment is vibrated during transportation, the first spring 6 and the damper 4 are used in combination to form a buffer between the arc plate 5 and the support plate 3, thereby buffering the prefabricated shaft on the top of the arc plate 5.
