Description

Technical Field

[0001] This invention relates to the field of large pipeline installation equipment technology, and in particular to an integrated jacking installation system. Background Technology

[0002] During construction, when assembling large prefabricated pipe components at heights, the large size and weight of these components often necessitate hoisting. This involves using a crane to lift each component individually to a designated installation height before assembly. Currently, there is no suitable jacking equipment to achieve the overall jacking and installation of batches of prefabricated pipe components, leading to an increase in construction time. Therefore, we propose an overall jacking and installation system. Summary of the Invention

[0003] The main objective of this invention is to provide an overall lifting and installation system that uses hydraulic lifting to achieve batch overall lifting of large prefabricated pipelines, which can shorten the overall construction cycle of the pipeline and effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An integrated jacking and installation system for the integrated jacking and installation of large prefabricated pipelines includes a jacking support, a hydraulic jack, a jacking hydraulic pipe, a combined hydraulic and air distribution manifold, a pneumatic compressor, and a prefabricated assembly bracket. The jacking support is horizontally fixed to the ground, and a hydraulic jack is mounted on its top. The head end of the hydraulic jack is fixedly connected to the prefabricated assembly bracket. Both the oil inlet and outlet of the hydraulic jack are connected to the hydraulic pipe, and the other end of the hydraulic pipe is connected to the combined hydraulic and air distribution manifold, which is connected via a high-pressure pipeline. The system includes a pneumatic compressor. A three-way valve is installed in the middle section of the high-pressure pipeline. The port of the three-way valve is connected to a climbing hydraulic combined air distributor via another high-pressure pipeline. The output end of the climbing hydraulic combined air distributor is connected to a climbing hydraulic pipe. The other end of the climbing hydraulic pipe is connected to a hydraulic climbing jack. The base end and the top end of the hydraulic climbing jack are respectively connected to a climbing frame and a base frame. Both the climbing frame and the base frame are equipped with a pulley system on their inner sides. Both the climbing frame and the base frame are connected to the lifting support via the pulley system. The upper end of the climbing frame is fixedly connected to the base of the hydraulic lifting jack.

[0006] Furthermore, to facilitate the manufacturing and assembly of the lifting support, the lifting support is composed of lifting units stacked vertically. The lifting unit is a frame structure welded from square steel, and each of the four corners of the upper end of the lifting unit is provided with a tenon groove, and the lower end is provided with a mortise at the corresponding position of the tenon groove. Through the mutual cooperation of the tenon groove and the mortise, the rapid positioning and assembly of adjacent lifting units can be achieved.

[0007] Furthermore, in order to improve the overall strength of the prefabricated assembly support and reduce the processing difficulty of the prefabricated assembly support, the prefabricated assembly support includes a transverse support beam, a longitudinal support beam and a partition beam. The transverse support beams are evenly distributed on the upper side of the hydraulic jack. The ends of the longitudinal support beams are fixedly connected to the transverse support beams and are perpendicular to each other. The partition beams are fixedly installed on the upper end of the transverse support beams in a vertical state.

[0008] Furthermore, to facilitate switching between the system's jacking and climbing states, control valves are installed in the middle of the high-pressure pipeline.

[0009] Furthermore, in order to simplify the system structure, enhance the system strength, and compensate for the deficiency of insufficient lifting height, both the climbing frame and the base frame are frame structures welded from square steel, and both are fitted and installed on the outside of the lifting support. The side end of the climbing frame without the hydraulic climbing jack is the mounting surface, and the distance between the upper and lower square steel bars at the mounting surface is not less than 1.5 times the overall height of the lifting unit.

[0010] Furthermore, to facilitate the lifting of the climbing frame and the base frame, reduce mutual friction between the equipment and improve operational stability, the pulley assembly includes a body and pulleys. The body has an L-shaped cross-section, and the pulleys are rotatably connected to the body. The pulleys are evenly distributed in the middle of the inner end face of the body, while the outer end face of the body is fixedly connected to both the climbing frame and the base frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The overall jacking installation system proposed in this invention first assembles the prefabricated pipes at a height of one meter on the ground during jacking. After assembly, pipes of various sizes are evenly laid on the upper end of the prefabricated assembly support. The air compressor is started, and the air compressor distributes the pressurized air evenly to the hydraulic jacking jack through the jacking hydraulic combined air distribution outlet, so that the top end of the hydraulic jacking jack rises and the prefabricated assembly support and prefabricated pipes are jacked to the installation position height. The hydraulic jacking method is used to realize the batch overall jacking of large prefabricated pipes, which can shorten the overall construction cycle of the pipes, with good jacking effect, low construction difficulty, and high safety.

[0013] (2) When the required lifting height exceeds the maximum stroke of the hydraulic lifting jack, the air compressor is connected to the climbing hydraulic combined air distribution pipe through the control valve. The climbing hydraulic combined air distribution pipe pumps high-pressure air into the hydraulic climbing jack, causing the end of the hydraulic climbing jack to extend and push the climbing frame upward. The climbing frame pushes the prefabricated assembly support upward a certain distance, so that the upper end face of the lifting unit located on the uppermost side of the lifting support and the lower end face of the climbing frame are on the same horizontal plane. Then, another lifting unit is added into the climbing frame through the addition face, so that the tenon groove of the added lifting unit matches the tenon of the original uppermost lifting unit and is reliably fixed. After that, the control valve is closed, the end of the hydraulic climbing jack is reset, and the bolts connecting the base frame and the lifting support are removed. The lifting support can be raised. With this setting, the system does not need to use a hydraulic lifting jack with a large stroke. It can lift the pipeline to a higher level by simply increasing the height of its own lifting support. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

[0023] Example 1

[0024] like Figure 1-3 As shown, an integrated jacking installation system for the integrated jacking installation of large prefabricated pipes includes a jacking support 1, a hydraulic jacking jack 2, a jacking hydraulic pipe 3, a jacking hydraulic combined air distribution manifold 4, a pneumatic compressor 5, and a prefabricated assembly bracket 6. The jacking support 1 is horizontally fixed to the ground, and a hydraulic jacking jack 2 is mounted on its top. The top end of the hydraulic jacking jack 2 is fixedly connected to the prefabricated assembly bracket 6. The oil inlet and outlet of the hydraulic jacking jack 2 are both connected to the jacking hydraulic pipe 3, and the other end of the jacking hydraulic pipe 3 is connected to the jacking hydraulic combined air distribution manifold 4. The jacking hydraulic combined air distribution manifold 4 is connected to a high-pressure pipeline... A pneumatic compressor 5 is connected to a three-way valve in the middle of a high-pressure pipeline. The port of the three-way valve is connected to a climbing hydraulic combined air distribution manifold 7 through another high-pressure pipeline. The output end of the climbing hydraulic combined air distribution manifold 7 is connected to a climbing hydraulic pipe 16. The other end of the climbing hydraulic pipe 16 is connected to a hydraulic climbing jack 8. The base end and the top end of the hydraulic climbing jack 8 are respectively connected to a climbing frame 9 and a base frame 10. Both the climbing frame 9 and the base frame 10 are equipped with a pulley assembly 11 on their inner sides. Both the climbing frame 9 and the base frame 10 are connected to the lifting support 1 through the pulley assembly 11. The upper end of the climbing frame 9 is fixedly connected to the base of the hydraulic lifting jack 2.

[0025] During the jacking process, the prefabricated pipes are first assembled at a height of one meter above the ground. After assembly, the pipes of various sizes are then arranged as follows: Figure 1 The prefabricated assembly support 6 is evenly laid on the upper end of the prefabricated assembly support 6. The air compressor 5 is started. The air compressor 5 distributes the pressurized air evenly to the hydraulic jack 2 through the lifting hydraulic combined air distribution 4, so that the top end of the hydraulic jack 2 rises and lifts the prefabricated assembly support 6 and the prefabricated pipe to the installation position height.

[0026] To facilitate the fabrication and assembly of the lifting support 1, the lifting support 1 is constructed by vertically stacking lifting units 101. The lifting unit 101 is a frame structure welded from square steel, and each of the four corners of the upper end of the lifting unit 101 is provided with a tenon 102, and the lower end is provided with a mortise 103 at the corresponding position of the tenon 102. Through the mutual cooperation of the tenon 102 and the mortise 103, the rapid positioning and assembly of adjacent lifting units 101 can be achieved. Before the lifting operation, the lifting support 1 of the corresponding height needs to be assembled according to the assembly position of the prefabricated pipe. During assembly, the adjacent lifting units 101 should be reliably fixed, and the upper surface of the assembled lifting support 1 should be on the same horizontal plane to ensure the stability of the lifting process.

[0027] To improve the overall strength of the prefabricated assembly support 6 and reduce its processing difficulty, the prefabricated assembly support 6 includes a transverse support beam 601, a longitudinal support beam 602, and a partition beam 603. The transverse support beams 601 are evenly distributed on the upper side of the hydraulic jack 2. The ends of the longitudinal support beams 602 are fixedly connected to the transverse support beams 601 and are perpendicular to each other. The transverse support beams 601 and the longitudinal support beams 602 are staggered, which can improve the overall rigidity of the prefabricated assembly support 6 and facilitate assembly. The partition beams 603 are fixedly installed vertically on the upper end of the transverse support beams 601 and are used to separate multiple prefabricated pipes to ensure that the prefabricated pipes do not sway during the jacking process, thus preventing a decrease in system stability.

[0028] Example 2

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, an integrated jacking installation system for the integrated jacking installation of large prefabricated pipes includes a jacking support 1, a hydraulic jacking jack 2, a jacking hydraulic pipe 3, a jacking hydraulic combined air distribution manifold 4, a pneumatic compressor 5, and a prefabricated assembly bracket 6. The jacking support 1 is horizontally fixed to the ground, and a hydraulic jacking jack 2 is mounted on its top. The top end of the hydraulic jacking jack 2 is fixedly connected to the prefabricated assembly bracket 6. The oil inlet and outlet of the hydraulic jacking jack 2 are both connected to the jacking hydraulic pipe 3, and the other end of the jacking hydraulic pipe 3 is connected to the jacking hydraulic combined air distribution manifold 4. The jacking hydraulic combined air distribution manifold 4 is connected to a high-pressure pipeline... A pneumatic compressor 5 is connected to a three-way valve in the middle of a high-pressure pipeline. The port of the three-way valve is connected to a climbing hydraulic combined air distribution manifold 7 through another high-pressure pipeline. The output end of the climbing hydraulic combined air distribution manifold 7 is connected to a climbing hydraulic pipe 16. The other end of the climbing hydraulic pipe 16 is connected to a hydraulic climbing jack 8. The base end and the top end of the hydraulic climbing jack 8 are respectively connected to a climbing frame 9 and a base frame 10. Both the climbing frame 9 and the base frame 10 are equipped with a pulley assembly 11 on their inner sides. Both the climbing frame 9 and the base frame 10 are connected to the lifting support 1 through the pulley assembly 11. The upper end of the climbing frame 9 is fixedly connected to the base of the hydraulic lifting jack 2.

[0030] When the required lifting height exceeds the maximum stroke of the hydraulic jack 2, the base frame 10 and the lifting support 1 are rigidly connected by bolts. After fixing, the control valve 14 connects the pneumatic compressor 5 to the climbing hydraulic combined air distributor 7. The climbing hydraulic combined air distributor 7 pumps high-pressure air into the hydraulic climbing jack 8, causing the end of the hydraulic climbing jack 8 to extend and push the climbing frame 9 upward. The climbing frame 9 moves relative to the lifting support 1 through the pulley block 11, pushing the prefabricated assembly bracket 6 upward a certain distance, so that the lifting unit 101 located on the uppermost side of the lifting support 1... The lower end face of the mounting surface 15 of the upper end climbing frame 9 is on the same horizontal plane. Then, another lifting unit 101 is added into the climbing frame 9 through the mounting surface 15, so that the tenon 102 of the added lifting unit 101 matches the tenon 103 of the original uppermost lifting unit 101 and is reliably fixed. Then, the control valve 14 is closed to reset the end of the hydraulic climbing jack 8. The bolts connecting the base frame 10 and the lifting support 1 are removed, and the lifting support 1 can be raised. Then, the lifting steps in embodiment 1 are repeated to lift the prefabricated assembled bracket 6 again. This will not be described in detail here.

[0031] To facilitate the fabrication and assembly of the lifting support 1, the lifting support 1 is constructed by vertically stacking lifting units 101. The lifting unit 101 is a frame structure welded from square steel, and each of the four corners of the upper end of the lifting unit 101 is provided with a tenon 102, and the lower end is provided with a mortise 103 at the corresponding position of the tenon 102. Through the mutual cooperation of the tenon 102 and the mortise 103, the rapid positioning and assembly of adjacent lifting units 101 can be achieved. Before the lifting operation, the lifting support 1 of the corresponding height needs to be assembled according to the assembly position of the prefabricated pipe. During assembly, the adjacent lifting units 101 should be reliably fixed, and the upper surface of the assembled lifting support 1 should be on the same horizontal plane to ensure the stability of the lifting process.

[0032] To facilitate switching between the system's jacking and climbing states, control valves 14 are installed in the middle of the high-pressure pipeline 13. The flow direction of the compressed gas from the air compressor 5 can be controlled by the control valves 14, thereby switching between the system's jacking and climbing states as needed.

[0033] To simplify the system structure, enhance system strength, and compensate for insufficient lifting height, both the climbing frame 9 and the base frame 10 are welded square steel frame structures, and are both fitted and installed on the outside of the lifting support 1. The side end of the climbing frame 9 without the hydraulic climbing jack 8 is the mounting surface 15. The distance between the upper and lower square steel bars at the mounting surface 15 is not less than 1.5 times the overall height of the lifting unit. This setting facilitates the installation of the lifting unit 101.

[0034] To facilitate the lifting of the climbing frame 9 and the base frame 10, reduce mutual friction between the equipment, and improve operational stability, the pulley block 11 includes a body 111 and pulleys 112. The body has an L-shaped cross-section. The pulleys 112 are rotatably connected to the body 111, and are evenly distributed in the middle of the inner end face of the body 111. The outer end face of the body 111 is fixedly connected to both the climbing frame 9 and the base frame 10.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
