Description

Technical Field

[0001] This utility model relates to the technical field of precast concrete pipe hoisting equipment, and specifically to a pipe hoisting device. Background Technology

[0002] Precast concrete pipes are widely used in underground pipe networks. When storing, loading, unloading, and installing precast concrete pipes, a "U"-shaped lifting tool is typically used. The "U"-shaped lifting tool has an opening on the side; when lifting precast concrete pipes, the tool is inserted into the upper wall of the pipe through the side opening and then lifted. The "U"-shaped lifting tool has the following disadvantages: First, there is no pipe restraint device at the side opening of the "U"-shaped lifting tool, posing a risk of pipe slippage during lifting and a significant safety hazard. Second, the "U"-shaped lifting tool cannot be used for lifting pipes of different lengths, requiring customization based on pipe length, which increases construction costs.

[0003] Chinese patent document with application number 201922107302.X discloses an adjustable hoisting device for reinforced concrete pipes, including a top plate whose upper end can be connected to a hook of a hoisting device, a crossbeam fixedly connected to the lower end of the top plate, two sliding lifting rings respectively installed at both ends of the crossbeam and each capable of moving left and right along the crossbeam, and two hooks respectively connected to the two sliding lifting rings, with the reinforced concrete pipe clamped between the two hooks. This adjustable hoisting device for reinforced concrete pipes has the following shortcomings: 1) Although the chute lifting ring can move left and right along the crossbeam to adjust the spacing to accommodate reinforced concrete pipes of different lengths, the crossbeam is fixed. When facing shorter reinforced concrete pipes, the two ends of the crossbeam need to protrude a long distance outward relative to the reinforced concrete pipe, which is easily obstructed by the external environment and affects the lifting operation. When facing longer reinforced concrete pipes, the crossbeam cannot be extended, making it difficult to meet the lifting requirements and resulting in poor adaptability. 2) When lifting a reinforced concrete pipe by clamping it with two hooks, since both hooks are rotatably connected to the crossbeam, the clamping action of the two hooks can only be used by external mechanisms (such as tightening the two hooks with ropes). This is cumbersome and inefficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pipe hoisting device that is telescopic and adjustable, easy to hoist, and highly adaptable.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A pipe hoisting device includes a main beam and two sliding beams. The two sliding beams are slidably sleeved to both ends of the main beam. A locking component for locking the main beam and each sliding beam is provided. A hook is provided at the outer cantilever end of each sliding beam. The hooks on the two sliding beams are respectively hooked to both ends of the pipe. The main beam is provided with lifting lugs.

[0006] As a further improvement to the above technical solution: The locking assembly includes a locking bolt and a sliding groove on the sliding beam. The locking bolt is located on the main beam and passes through the sliding groove.

[0007] The main beam is provided with a bearing slot on each of its left and right halves, and the sliding beam is inserted into the corresponding bearing slot.

[0008] The locking bolts are provided in multiple quantities and are arranged at intervals along the length of the main beam.

[0009] The main beam has a transverse through hole at the location of the locking bolt, and the locking bolt passes through the transverse through hole.

[0010] Both the main beam and the sliding beam have square cross-sections.

[0011] The hook is hinged to the sliding beam, and the sliding beam is provided with a locking element for locking the hook.

[0012] The locking element is a locking pin parallel to the rotation axis of the hook. The hook has a first locking hole, and the sliding beam has a second locking hole corresponding to the first locking hole. The locking element passes through the corresponding first and second locking holes.

[0013] The bottom of the sliding beam is fixedly provided with a hinge seat, the hook is hinged to the hinge seat, and the second locking hole is provided on the hinge seat.

[0014] The hook is L-shaped, with one end hinged to the sliding beam and the other end used to hook the pipe.

[0015] Compared with the prior art, the advantages of this utility model are: One usage process of the pipeline hoisting device of this utility model is as follows: First, the main beam is hoisted onto the hoisting equipment via lifting lugs; second, the hoisting equipment lifts the entire pipeline hoisting device to a suitable position above the pipeline; next, the sliding beams are slidably adjusted relative to the main beam so that the total length of the sliding beams and the main beams meets the length requirements of the pipeline, and the hooks on the two sliding beams are engaged and hooked onto both ends of the pipeline respectively; finally, the pipeline is transported to the required position by the hoisting equipment. On one hand, the main beam and the two sliding beams form a telescopically adjustable hoisting rod, and the hooks are located at the outer cantilever ends of the sliding beams, adjusting their position as the length of the hoisting rod changes. Thus, for shorter pipelines (close to the shortest length of the hoisting rod), the hoisting rod can retract to a very short length under the sliding action of the sliding beams, thereby reducing the outward cantilever length, making it less susceptible to obstruction by the external environment and facilitating hoisting operations; for longer pipelines, the hoisting rod can extend to meet its hoisting requirements, demonstrating strong adaptability.

[0016] This utility model's pipe lifting device maintains a constant boom length when lifting pipes of the same length. By simply unlocking and locking the locking mechanism, the hooks on the two sliding beams can be hooked onto both ends of the pipe. For example, first unlock the hook on the first sliding beam, hook the hook on the second sliding beam onto the other end of the pipe, and then use the rotation and locking function of the hook on the first sliding beam to hook it onto one end of the pipe. This eliminates the need for sliding beams to achieve the hooking operation and removes the need for external mechanisms to restrict the hooking action, resulting in simple operation and high efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0027] Figures 1 to 5 This invention illustrates one embodiment of the pipe hoisting device. The pipe hoisting device of this embodiment includes a main beam 1 and two sliding beams 2. The two sliding beams 2 are slidably connected to both ends of the main beam 1. A locking component 3 for locking the two is provided between the main beam 1 and each sliding beam 2. A hook 4 is provided at the outer cantilever end of each sliding beam 2. The hooks 4 on the two sliding beams 2 are respectively hooked to both ends of the pipe 6. A lifting lug 5 is provided on the main beam 1.

[0028] One usage process of this pipeline hoisting device is as follows: First, the main beam 1 is hoisted onto the hoisting equipment via the lifting lugs 5; second, the hoisting equipment lifts the entire pipeline hoisting device to a suitable position above the pipeline 6; next, the sliding beams 2 are slidably adjusted relative to the main beam 1 so that the total length of the sliding beams 2 and the main beam 1 meets the length requirement of the pipeline 6, and the hooks 4 on the two sliding beams 2 are engaged to hook onto both ends of the pipeline 6; finally, the pipeline 6 is transported to the required position by the hoisting equipment. On one hand, the main beam 1 and the two sliding beams 2 form a telescopically adjustable hoisting rod, and the hooks 4 are located at the outer cantilever ends of the sliding beams 2, adjusting their positions as the length of the hoisting rod changes. Thus, for shorter pipelines 6 (close to the shortest length of the hoisting rod), the hoisting rod can retract to a very short length under the sliding action of the sliding beams 2, thereby reducing the outward cantilever length, making it less susceptible to obstruction by the external environment and facilitating hoisting operations; for longer pipelines 6, the hoisting rod can extend to meet its hoisting requirements, demonstrating strong adaptability.

[0029] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the locking assembly 3 includes a locking bolt 31 and a groove 32 on the sliding beam 2. The locking bolt 31 is located on the main beam 1 and passes through the groove 32. When the locking bolt 31 is loose, it does not restrict the sliding of the sliding beam 2 on the main beam 1, thus meeting the requirements for adjusting the extension and retraction of the boom. When the locking bolt 31 is tightened, it locks the main beam 1 and the sliding beam 2.

[0030] Furthermore, in this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the main beam 1 has a socket 11 on each of its left and right halves, and the sliding beam 2 is inserted into the corresponding socket 11. That is, the main beam 1 is larger than the sliding beam 2, forming a suspension rod structure that is thicker in the middle and thinner at both ends, thereby improving the load-bearing capacity.

[0031] Furthermore, in this embodiment, multiple locking bolts 31 are provided and arranged at intervals along the length of the main beam 1. The main beam 1 and the sliding beam 2 are locked together by multiple locking bolts 31, which improves the connection strength and locking stability.

[0032] Furthermore, in this embodiment, the main beam 1 has a transverse through hole 7 at the location of the locking bolt 31, and the locking bolt 31 passes through the transverse through hole 7. Specifically, the transverse through hole 7 penetrates vertically through the main beam 1.

[0033] Furthermore, in this embodiment, both the main beam 1 and the sliding beam 2 have square cross-sections.

[0034] Furthermore, in this embodiment, the hook 4 is hinged to the sliding beam 2, and the sliding beam 2 is provided with a locking element 8 for locking the hook 4. Thus, when lifting pipes 6 of the same length, the length of the lifting rod can remain constant. By simply unlocking and locking the locking element 8, the hooks 4 on the two sliding beams 2 can be hooked onto both ends of the pipe 6. For example, first unlock the hook 4 on the first sliding beam 2, hook the hook 4 on the second sliding beam 2 onto the other end of the pipe 6, and then, through the rotation and locking function of the hook 4 on the first sliding beam 2, hook the hook 4 on the first sliding beam 2 onto one end of the pipe 6. This eliminates the need for sliding the sliding beams 2 to hook the pipe, and also eliminates the need for external mechanisms to restrict the hooks 4, making the operation simple and efficient.

[0035] Furthermore, in this embodiment, as Figure 3 As shown, the locking element 8 is a locking pin parallel to the rotation axis of the hook 4. The hook 4 is provided with a first locking hole 41, and the sliding beam 2 is provided with a second locking hole 21 corresponding to the first locking hole 41. The locking element 8 passes through the corresponding first locking hole 41 and second locking hole 21.

[0036] Furthermore, in this embodiment, a hinge seat 9 is fixedly provided at the bottom of the sliding beam 2, the hook 4 is hinged to the hinge seat 9, and the second locking hole 21 is provided on the hinge seat 9. Preferably, the hook 4 is L-shaped, one end of the hook 4 is hinged to the sliding beam 2, and the other end is used to hook the pipe 6.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
