Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly relates to a lifting device for installing heavy pipelines. Background Art

[0002] In large public buildings, the main pipes such as air-conditioning water pipes, heating pipes, and boiler flue gas pipes have large diameters, heavy pipe weights, large high-altitude installation workloads, many vertical transportation operations, and long horizontal transportation distances. During installation, it is necessary to transport, hoist, and weld large metal pipes in sections according to the characteristics of the site.

[0003] For hoisting, electric hoists or manual hoists can be used for lifting and installation. After mechanical calculations, two lifting lugs are welded on both sides of the metal pipe respectively, and steel wire ropes are hung on the lifting lugs respectively to vertically lift the metal pipe. After hoisting, the height of the pipe is adjusted by an electric hoist or a manual hoist, or a lift truck is used to lift the pipe to the corresponding height. When there is support at the bottom, manual dragging is used to translate the spatial position of the pipe, and after placing it on the support hanger, the assembly is completed and welded. Each section of the pipe is installed in sequence.

[0004] However, during the installation of large pipes, the safety of personnel and the transportation of the spatial position of the pipes are the most important goals. The problem of too long lifting time using an electric hoist or a manual hoist is inevitable, and due to the self-weight of the pipe and the additional force, the kinetic energy generated by the spatial displacement during transportation is extremely large, and the losses caused by collisions with personnel or related machinery may cause quite serious consequences.

[0005] Moreover, the drawback of using a conventional lift truck to transport pipes is that when oblique transportation is required due to obstacles, the anti-tilting and sliding ability of the pipe is poor, and after transporting to the designated height, it has little effect on lateral displacement. As a result, the manual workload is large and the safety factor is poor, which needs to be improved. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lifting device for installing heavy pipelines, which can facilitate the pipe to cross obstacles for lifting and can realize the full-automatic and all-round spatial position adjustment of the pipe.

[0016] In a preferred example of the present utility model, it can be further configured that: a plurality of sliding rollers are vertically and spacedly rotatably connected to the inner side wall of the clamping plate.

Detailed Embodiment

[0029] The following further describes the present utility model in detail with reference to the drawings.

[0030] As Figure 1 、 Figure 2 、 Figure 3 shown, a lifting device for heavy pipeline installation includes a pair of remote control electric vehicles 1, an elevator 2, a supporting platform 3, a clamping plate 4 and a limit plate 5.

[0031] As Figure 1 、 Figure 2 、 Figure 3 shown, a pair of remote control electric vehicles 1 are used for moving on the ground, and the elevator 2 is vertically arranged on the remote control electric vehicle. The supporting platform 3 is horizontally arranged at the upper end of the elevator 2, and one side close to the elevator 2 is horizontally rotatably connected to the elevator 2, and a hydraulic cylinder 21 for controlling the rotation of the supporting platform 3 is arranged on the elevator 2.

[0032] AsFigure 1 , Figure 2 , Figure 3 As shown in Figure 3 , the clamping plate 4 is vertically arranged on the supporting platform 3 and is used for clamping both sides of the pipeline. A plurality of electric rollers 31 are horizontally and rotatably connected at intervals in the middle position of the supporting platform 3. The electric rollers 31 are arranged between a pair of clamping plates 4. A plurality of sliding rollers 41 are vertically and rotatably connected at intervals on the inner side wall of the clamping plate 4.

[0033] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 3 , a sliding seat 42 horizontally slidably connected to the supporting platform 3 is horizontally arranged between the lower ends of a pair of clamping plates 4. An adjusting rod 32 is threadedly connected to the supporting platform 3, and the adjusting rod 32 is rotatably connected to the side wall of the sliding seat 42.

[0034] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 3 , sliders 43 horizontally slidably connected to the sliding seat 42 are arranged at the lower ends of a pair of clamping plates 4. A bidirectional lead screw 44 threadedly connected to the slider 43 is horizontally rotatably connected to the sliding seat 42.

[0035] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 3 , the limiting plate 5 is vertically slidably connected to the upper end of the elevator 2 and is used for abutting against the end of the pipeline.

[0036] When the pipeline needs to be lifted and installed, the two ends of the pipeline can be placed on a pair of supporting platforms 3, and then the bidirectional lead screw 44 is controlled to rotate, so that a pair of clamping plates 4 approach each other and clamp the pipeline, thereby realizing the limiting and fixing of the pipeline.

[0037] Subsequently, the elevator 2 can be used to control the vertical movement of the supporting platform 3 to realize the lifting and elevation of the pipeline. When the height position of the pipeline meets the requirements, the sliding control of the sliding seat 42 can be realized by controlling the rotation of the adjusting rod 32, thereby realizing the synchronous movement control of a pair of clamping plates 4 and driving the pipeline to slide horizontally to realize the adjustment of the horizontal position of the pipeline.

[0038] Subsequently, the electric rollers 31 are controlled to rotate, and the cooperation of the electric rollers 31 and the sliding rollers 41 is used to realize the adjustment of the pipeline in the longitudinal direction, facilitate the centering or calibration of the pipeline, quickly adjust the position of the pipeline, and realize the precise and rapid installation of the pipeline.

[0039] When an obstacle is encountered during the lifting process of the pipeline, the limiting plate 5 can be raised at this time, and then one of the elevators 2 is controlled to drive the supporting platform 3 to move downward, or one of the elevators 2 is controlled to drive the supporting platform 3 to move upward, so that a height difference is formed between the two supporting platforms 3 and the pipeline is supported in an inclined state.

[0040] Subsequently, the hydraulic cylinder 21 is used to control the rotation of the supporting platform 3 so that the two ends of the pipeline are integrally supported by the supporting platform 3. Subsequently, the pair of elevators 2 are controlled to move synchronously, and the pair of remote control electric vehicles 1 are controlled to move synchronously, so that the upper end of the inclined pipeline first crosses the obstacle, and then the elevator 2 at the lower position is controlled to move, and the hydraulic cylinder 21 is controlled to work synchronously to move the pipeline to a horizontal state for avoiding the obstacle.

[0041] Therefore, by setting the rotary supporting platform 3, when the pipeline is lifted, once there is an obstacle above, it can cooperate with the hoist to realize the oblique transportation and lifting of the pipeline or the translational movement after lifting with an angle conversion for avoiding the obstacle, so as to realize the full-automatic and all-round spatial position adjustment of the pipeline, which is convenient for the installation and construction operations of the pipeline.

[0042] During the working process of the device, the use of labor is saved, the cycle of the installation process is reduced, the safety of personnel and the surrounding environment is improved, and the arbitrary adjustment of the spatial position of the pipeline under a bad working environment can be realized, and the effect is remarkable.

[0043] Such as Figure 1 、 Figure 2 、 Figure 3 As shown, a hanging basket 6 is arranged on one side of the supporting platform 3, and a pair of hooks 61 for hooking and supporting the platform 3 are arranged on the hanging basket 6. Therefore, by setting the detachable hanging basket 6, after the pipeline is positioned, the construction personnel can be lifted, which is convenient for the construction personnel to carry out operations such as welding on the pipeline at a high place.

[0044] Such as Figure 1 、 Figure 2 、 Figure 3 As shown, support rods 7 are horizontally arranged around the remote control electric vehicle, and support feet 71 for abutting against the ground are vertically slidably connected to the support rods 7, so as to make the support feet 71 abut against the ground after the remote control electric vehicle stops stably, preventing the remote control electric vehicle from moving, thereby increasing the stability of the remote control electric vehicle during operation.

[0045] Such as Figure 1 、 Figure 2 、 Figure 3 As shown, a plurality of counterweights 8 are arranged on the remote control electric vehicle to increase the bottom counterweight of the whole device and prevent tipping, so as to realize the stable lifting and transportation of the pipeline.
