Description

Technical Field

[0001] This utility model belongs to the field of hydraulic engineering construction technology, and in particular relates to a concrete interlocking precast block laying hoist. Background Technology

[0002] In the construction of slope protection in hydraulic engineering, the laying of interlocking precast concrete blocks is a crucial step. Interlocking precast concrete blocks are block-shaped materials made of concrete that achieve an interlocking effect through specific design to enhance the stability and durability of the structure. To achieve efficient and safe laying, specialized lifting equipment is required to lift and move these precast blocks.

[0003] Existing lifting equipment is usually made by fixing the horizontal and vertical beams with nuts and then welding them together. During the lifting process, due to the heavy weight of the interlocking precast concrete blocks, the welded joints of the horizontal and vertical beams of the lifting equipment are easily subjected to large stresses, which can lead to cracks. This not only affects the service life of the lifting equipment, but may also pose a safety threat to construction workers. Utility Model Content

[0009] As a preferred embodiment of the above technical solution, the number of the inclined blocks is equal to the sum of the number of the vertical support blocks and the horizontal support blocks.

[0010] As a preferred embodiment of the above technical solution, the interior of the crossbeam, vertical beam and partition is provided with a slot, and the positioning nut is set as a T-shaped nut and inserted into the interior of the slot.

[0011] As a preferred embodiment of the above technical solution, both the vertical support block and the horizontal support block are connected to limit protrusions, and the inclined block has a limit groove inside, with the limit protrusion inserted into the limit groove.

[0012] As a preferred embodiment of the above technical solution, a spacer is provided between the screw and the vertical support block and the horizontal support block, and the spacer is used to increase the friction between the screw and the vertical support block and the horizontal support block.

[0013] As a preferred embodiment of the above technical solution, the bottom of the crossbeam and the vertical beam are connected with hanging ears, which are welded to the crossbeam and the vertical beam.

[0014] The beneficial effects of this utility model are as follows:

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a concrete interlocking precast block laying hoist, such as Figures 1 to 3 As shown, the concrete interlocking precast block laying hoist includes a horizontal beam 1, a vertical beam 2, a partition plate 3, and a support assembly. The horizontal beam 1 and the vertical beam 2 are fixed together by nuts and then welded together for connection with the hoisting equipment. Two sets of partition plates 3 are provided and welded to the two horizontal beams 1. The support assembly includes inclined blocks 4, vertical support blocks 5, horizontal support blocks 6, screws 7, and positioning nuts 8. Multiple sets of inclined blocks 4 are provided and connected to the horizontal beam 1, the vertical beam 2, and the partition plate 3 respectively. The vertical support blocks 5 and the horizontal support blocks 6 are both connected to the inclined blocks 4, and the total number of vertical support blocks 5 and horizontal support blocks 6 is equal to the number of inclined blocks 4. Multiple screws 7 are provided and connected to the vertical support blocks 5 and the horizontal support blocks 6. The positioning nuts 8 are installed on the outer surface of the screws 7 by threaded connection. The vertical support blocks 5 and the horizontal support blocks 6 are used to fix the inclined blocks 4 inside the hoist.

[0024] In this embodiment, multiple lugs 12 are welded to the bottom of the crossbeam 1 and the vertical beam 2. The lugs 12 are used to connect with the hoisting ropes. Limiting protrusions 10 are fixedly connected to the outer surfaces of the vertical support block 5 and the horizontal support block 6. Limiting grooves 11 are opened inside the inclined block 4, and the limiting protrusions 10 are inserted into the limiting grooves 11.

[0025] By installing the vertical support block 5 and the horizontal support block 6 between each pair of inclined blocks 4, and then passing the screw 7 through the vertical support block 5 and the horizontal support block 6 and threading it into the positioning nut 8, the vertical support block 5 and the horizontal support block 6 can be fixedly installed on the lifting device, providing a stable support effect for the lifting of the horizontal beam 1 and the vertical beam 2.

[0026] When using it, the vertical support block 5 and the horizontal support block 6 need to be installed inside the lifting device. Figure 1 As shown, the limiting protrusions 10 connected to the vertical support block 5 and the horizontal support block 6 are respectively inserted into the limiting grooves 11. Then, the screw 7 is passed through the vertical support block 5 and the horizontal support block 6, and the end of the screw 7 is threaded into the positioning nut 8. This allows the vertical support block 5 and the horizontal support block 6 to be firmly installed between each pair of inclined blocks 4, preventing slippage. At the same time, under the action of the inclined blocks 4, the vertical support block 5 and the horizontal support block 6, the lifting device can effectively reduce the stress on the weld joints during lifting operations, reducing the risk of cracks at the weld joints of the horizontal beam 1 and the vertical beam 2.

[0027] The interior of the crossbeam 1, vertical beam 2, and partition 3 is also provided with slots 9. The positioning nut 8 is specifically set as a T-shaped nut, and when the positioning nut 8 is inserted into the interior of the slot 9, the rectangular outer surface of the positioning nut 8 can fit against the inner wall of the slot 9. This allows the positioning nut 8 to be stably inserted into the interior of the crossbeam 1, vertical beam 2, and partition 3 when the screw 7 is installed inside the positioning nut 8 through a threaded connection, avoiding the risk of the positioning nut 8 rotating and slipping off during hoisting operations, and improving the stability and safety of the hoisting process.

[0028] like Figure 1 As shown, in this embodiment, four sets of inclined blocks 4 are installed between two sets of partitions 3 to support two sets of vertical support blocks 5 and two sets of horizontal support blocks 6 in the middle four sets of inclined blocks 4. The two sets of vertical support blocks 5 are fixedly supported by two sets of screws 7 and positioning nuts 8 respectively, and the two sets of horizontal support blocks 6 are fixedly supported by one set of screws 7 and positioning nuts 8 respectively.

[0029] Specifically, when the screw 7 is threaded through the vertical support block 5 and the horizontal support block 6 and installed into the positioning nut 8, a spacer is provided between the screw 7 and the vertical support block 5 and the horizontal support block 6. The spacer is made of stainless steel, which has excellent corrosion resistance and oxidation resistance and can resist rust in various environments. At the same time, the surface of the stainless steel spacer is treated with sandblasting, wire drawing and other techniques to improve the surface roughness of the spacer and increase the friction between the screw 7 and the vertical support block 5 and the horizontal support block 6.

[0030] Working principle: The specific installation process of this lifting device is as follows:

[0031] The limiting protrusions 10 fixedly installed on the vertical support block 5 and the horizontal support block 6 are respectively inserted into the limiting grooves 11. Then, the screw 7 is passed through the vertical support block 5 and the horizontal support block 6. Subsequently, the positioning nut 8 is inserted into the slots 9 opened on the crossbeam 1, the vertical beam 2 and the partition plate 3, and the screw 7 is rotated so that its end thread is installed into the interior of the positioning nut 8. Then, the vertical support block 5 and the horizontal support block 6 are fixedly installed between every two inclined blocks 4. Under the action of the inclined blocks 4, the vertical support block 5 and the horizontal support block 6, a stable support effect can be provided for the welded crossbeam 1 and the vertical beam 2. This allows the lifting tool to effectively reduce the stress at the welding position of the crossbeam 1 and the vertical beam 2 during lifting operations, thereby reducing the risk of cracks at the welding position and extending the service life of the lifting tool.

[0032] By using screw 7 and positioning nut 8, the vertical support block 5 and the horizontal support block 6 can be easily installed on the lifting device. The screw 7 and positioning nut 8 can be disassembled by reversing the above installation operation, which simplifies the assembly and disassembly process of the lifting device and saves manpower and time costs.

[0033] After the lifting device is installed, it is connected to the lifting equipment and the lifting rope is connected to the lug 12. Then, the precast concrete interlocking block to be lifted is connected to the lifting rope, and the lifting equipment can be operated to complete the lifting operation.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
