Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a building pipe lifting device used in building engineering construction. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Construction pipes are often used in the construction process of construction projects, and pipe hoists are needed to lift the construction pipes to a high place.

[0003] For example, the Chinese patent with publication number CN211713695U discloses a pipe lifting device for bridge construction, which relates to the technical field of bridge construction related equipment. Some existing pipes are long, or of different lengths, and are smooth, which makes it difficult to fix them before lifting, and therefore it is not easy to lift and hoist them, which will affect the construction progress. The following scheme is proposed, a hanger, a pull rope, a hook and a pipe fixing device, wherein the pipe fixing device is movably mounted on the hook, and the pipe fixing device includes a first pipe fixing end plate and a second pipe fixing end plate. The utility model can load and hoist pipes of different lengths, and can load and hoist single pipes and multiple pipes, which is convenient for on-site operation according to actual conditions. During the loading and hoisting process, it can prevent the pipe from falling due to the instability of the telescopic connecting rod causing the length change during the lifting process. It is easy to remove during on-site construction, which is convenient for the hanger to lift different construction materials during construction, which is convenient for construction.

[0004] However, this patent and most current pipe lifting devices require workers to lift the pipe into a placement trough, and then use a crane or other lifting device to drive the pipe up. In some cases, the weight of the pipe is large, and after the pipe is transported to the construction site, it is difficult for workers to lift it and place it in the placement trough, which is inconvenient for workers to use.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1 to 3The utility model discloses a construction pipe lifting device for construction engineering, comprising a top plate 1, the top of which is connected to the output end of a crane through a lifting rope. Two fixed plates 2 are fixedly connected to the bottom of the top plate 1, a threaded barrel 3 is arranged below the top plate 1, the threaded barrel 3 rotates through the two fixed plates 2, a driving part 4 is arranged above the threaded barrel 3, two screws 5 are connected to the inner thread of the threaded barrel 3, a moving block 6 is fixedly connected to the end of the screw 5 away from the threaded barrel 3, a limiting part 7 is arranged above the moving block 6, a side plate 8 is fixedly connected to the bottom of the moving block 6, and a support barrel 9 is fixedly connected to the side of the side plate 8 close to the threaded barrel 3.

[0025] In this embodiment, the crane tightens the rope when working, thereby driving the top plate 1 to move up and down. The driving part 4 drives the threaded barrel 3 to rotate, and the threaded barrel 3 drives the two screws 5 to move in the opposite direction when rotating, thereby adjusting the distance between the two moving blocks 6.

[0026] In the initial state, the distance between the two support cylinders 9 is greater than the length of the pipe. The staff moves the top plate 1 to a suitable position so that the two support cylinders 9 are located at both ends of the pipe. Then the driving unit 4 works to insert the two support cylinders 9 into the ends of the pipe until the side plate 8 fits the end surface of the pipe. At this time, the crane drives the device to move upward, and the support cylinder 9 moves upward to contact the inner wall of the pipe and drives the pipe to move upward, thereby lifting the pipe.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the limiting portion 7 includes a plurality of limiting grooves 71 opened on the side wall of the top plate 1, and a plurality of limiting plates 72 are fixedly connected to the top of the moving block 6. The limiting plates 72 are L-shaped, and the horizontal sections of the limiting plates 72 are slidably connected to the corresponding limiting grooves 71.

[0028] In this embodiment, the limiting plate 72 can only slide in the corresponding limiting groove 71, so that the moving block 6 can only move linearly.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the driving part 4 includes a motor fixedly connected to the bottom of the top plate 1, the output end of the motor is transmission-connected with a driving bevel gear, the outer circumference of the threaded cylinder 3 is fixedly sleeved with a driven bevel gear, and the driving bevel gear is meshed with the driven bevel gear.

[0030] In this embodiment, the motor drives the driving bevel gear to rotate, and the driving bevel gear drives the driven bevel gear to rotate, thereby driving the threaded cylinder 3 to rotate.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, two handles 10 are fixedly connected to the top surface of the top plate 1 .

[0032] In this embodiment, when the motor is working, the staff holds the corresponding handle 10 to fix the top plate 1 to prevent the top plate 1 from shaking violently when the motor is working, which may cause the support tube 9 to be unable to be inserted into the pipe.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, a cavity 11 is opened in the support tube 9, and an electric push rod 12 is fixedly penetrated on the side of the side plate 8 away from the support tube 9, and the output end of the electric push rod 12 extends into the cavity 11, and the output end of the electric push rod 12 is fixedly connected to a driving plate 13, and a plurality of sliding plates 14 are slidably penetrated on the inner circumference of the cavity 11, and a fixed block 15 is fixedly connected to one end of the sliding plate 14 located outside the support tube 9, and a plurality of connecting plates 16 are hinged on one side of the driving plate 13, and the end of the connecting plate 16 away from the driving plate 13 is hinged to the corresponding sliding plate 14.

[0034] In this embodiment, after the support tube 9 is inserted into the pipe, the electric push rod 12 drives the driving plate 13 to move, and the driving plate 13 drives the sliding plate 14 to slide out of the cavity 11 through the connecting plate 16, thereby driving the fixing block 15 to contact the inner wall of the pipe, fixing the pipe from the inside of the pipe, and further preventing the pipe from shaking during the lifting process.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, the two side panels 8 are arranged in a mirror image with respect to the center plane of the top panel 1 .

[0036] In this embodiment, since the side plate 8 fits the end surface of the pipe, the center plane of the pipe is ensured to be coplanar with the center plane of the top plate 1. Therefore, when the pipe is lifted, the force on both sides of the device is uniform and no tilting occurs.

[0037] The implementation principle of the above embodiment is:

[0038] In the initial state, the distance between the two support tubes 9 is greater than the length of the pipe. The staff holds the handle 10 and moves the top plate 1 to a suitable position so that the two support tubes 9 are located at both ends of the pipe, and then starts the motor to drive the threaded tube 3 to rotate, and the threaded tube 3 drives the two screws 5 and the two moving blocks 6 to move toward each other, and the moving blocks 6 drive the side plates 8 and the support tube 9 to move, and the support tube 9 is inserted into the pipe, and the side plates 8 fit the end surface of the pipe. At this time, the motor is turned off and the staff releases the handle 10.

[0039] Then the electric push rod 12 works to drive the driving plate 13 to move, and the driving plate 13 drives the sliding plate 14 to slide out of the cavity 11 through the connecting plate 16, thereby driving the fixing block 15 to contact the inner wall of the pipe. Finally, several fixing blocks 15 are in contact with the inner wall of the pipe to limit the rotation of the pipe.

[0040] Then the crane works to lift the top plate 1, thereby driving the pipe to rise. When the pipe is lifted, the crane places the pipe at the corresponding position, the electric push rod 12 moves in the reverse direction, the fixed block 15 returns to its original position, the motor rotates in the reverse direction, the support tube 9 is separated from the inside of the pipe, and then the crane transfers the device to the next pipe that needs to be lifted to continue the operation.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
