Description

Technical Field

[0001] The present application relates to the technical field of large-scale steel pipe gallery construction equipment, and in particular to a large-scale steel pipe gallery mobile jacking device and a construction method. Background Art

[0002] In petrochemical plants, the structure of the public engineering pipeline corridor is mostly in the form of concrete columns at the bottom and steel structure at the top. Pipelines, electrical cables, etc. are distributed on the upper part of the steel structure. The wheelbase and axis spacing of the concrete columns are generally 6-9 meters, and the height of the concrete columns is generally about 6 meters. The upper steel structure is about 20 meters high and weighs about 150 tons. The characteristics of the steel pipeline corridor are large size and light weight.

[0003] In order to realize the modular prefabrication and installation of the steel structure on the top of the concrete column of the pipe gallery and the attached pipelines and electrical instrument brackets, the installation was mostly carried out by prefabrication in the prefabrication yard, transportation of the axis plate, and on-site hoisting. The construction of the pipe gallery is characterized by large workload and operation area, and tight construction period. Secondly, the amount of pipes used is large, the operation front is long, and the workload is large; in addition, the large and light steel pipe gallery is transported by an integral axis vehicle, which increases the cost; finally, there are many high-altitude operations and hoisting operations, the construction operation area is large, and the construction organization is difficult.

[0004] When hoisting the steel pipe gallery, crawler cranes are used for installation. It is necessary to select crawler cranes of corresponding tonnage according to the size and weight of the steel pipe gallery. The tonnage of crawler cranes is limited by the size and weight of the steel pipe gallery, and the hoisting capacity is poor and the cost is high. When hoisting the steel pipe gallery, crawler cranes will occupy the road. Due to the slow hoisting speed, crawler cranes occupy the road for a long time, affecting the passage of other vehicles in the site. In addition, crawler cranes have relatively high requirements for the hardening conditions of the road at the station, and the station needs to be treated with foundation. Summary of the invention

[0054] See also Figures 1 to 4 As shown, the first aspect of the embodiment of the present application provides a large-scale steel pipe gallery mobile jacking device, comprising:

[0055] The steel pipe gallery lifting assembly 10 includes a lower support seat 11 and a steel pipe gallery support frame 12 located above the lower support seat 11. A lifting mechanism 13 for lifting the steel pipe gallery support frame 12 to a set height is provided on the lower support seat 11. The lower support seat 11 provides a bottom foundation for the steel pipe gallery support frame 12 and the lifting mechanism 13. The lifting mechanism 13 lifts the steel pipe gallery support frame 12 to a set height by adjusting its own height. The steel pipe gallery support frame 12 is used to connect the steel pipe gallery 40, thereby stably supporting the steel pipe gallery 40 on the steel pipe gallery support frame 12.

[0056] The jacking assembly transport vehicle includes a self-propelled module transport vehicle 30 located at the bottom of the steel pipe gallery jacking assembly 10 for synchronously moving the steel pipe gallery jacking assembly 10 and the steel pipe gallery 40 to the set work station, and the lower support seat 11 is fixed on the top of the self-propelled module transport vehicle 30.

[0057] The large-scale mobile jacking device of the embodiment of the present application is provided with a steel pipe gallery jacking assembly 10 for lifting the steel pipe gallery 40, and the steel pipe gallery jacking assembly 10 is provided with a lower support seat 11 fixed on the top of the self-propelled module transport vehicle 30, and a steel pipe gallery support frame 12 is provided above the lower support seat 11, and a jacking mechanism 13 for lifting the steel pipe gallery support frame 12 to a set height is provided on the lower support seat 11. The self-propelled module transport vehicle 30 is used to transport the steel pipe gallery jacking assembly 10 and the steel pipe gallery 40 from the steel pipe gallery prefabrication site to the steel pipe gallery to be installed. After the steel pipe gallery 40 is transported to the steel pipe gallery to be installed, the steel pipe gallery jacking assembly 10 lifts the steel pipe gallery 40 to the top of the steel pipe gallery concrete column 50 and places it on the steel pipe gallery concrete column 50, completing the transportation and installation of the steel pipe gallery 40.

[0058] The embodiment of the present application adopts a split self-propelled modular transport vehicle 30 to transport the steel pipe corridor 40. Multiple self-propelled modular transport vehicles 30 are flexible to operate and improve transportation efficiency, solving the problem of high transportation costs of using an integral axle vehicle. The self-propelled modular transport vehicle 30 can be assembled in longitudinal and transverse connection, and can adapt to the transportation of objects of different tonnages. It has a wide range of applications and solves the problem of limited quality and size of the steel pipe corridor 40. The steel pipe corridor jacking assembly 10 and the self-propelled modular transport vehicle 30 use a low-position transportation and high-position installation method to install the steel pipe corridor 40. Compared with the crawler crane hoisting construction, it has high alignment accuracy, solves the problem of large shaking and poor accuracy of crane hoisting, and the equipment occupies a small area, is safe and efficient, and has a high degree of automation and intelligence.

[0059] In some alternative embodiments: See Figures 1 to 3 As shown, the embodiment of the present application provides a large-scale steel pipe gallery mobile jacking device, wherein the steel pipe gallery support frame 12 of the large-scale steel pipe gallery mobile jacking device includes a left longitudinal beam 121 and a right longitudinal beam 122 which are parallel to each other and spaced apart, a front cross beam 123 and a rear cross beam 124 which connect the left longitudinal beam 121 and the right longitudinal beam 122 into one body, and an intermediate longitudinal beam 125 which connects the front cross beam 123 and the rear cross beam 124, and the jacking mechanism 13 is connected to the intermediate longitudinal beam 125. The left longitudinal beam 121, the right longitudinal beam 122, the front cross beam 123, the rear cross beam 124 and the intermediate longitudinal beam 125 are all processed and formed by steel profiles.

[0060] The front cross beam 123 and the rear cross beam 124 are parallel to each other and spaced apart. The middle of the front cross beam 123 and the rear cross beam 124 are provided with guide slots for sliding connection with the middle longitudinal beam 125. After the two ends of the middle longitudinal beam 125 are respectively connected with the front cross beam 123 and the rear cross beam 124 through the guide slots, the left longitudinal beam 121, the right longitudinal beam 122, the front cross beam 123 and the rear cross beam 124 move relatively to the middle longitudinal beam 125 along the width direction of the middle longitudinal beam 125.

[0061] The left longitudinal beam 121 and the right longitudinal beam 122 of the embodiment of the present application are symmetrically arranged on both sides of the lower support seat 11, and the lower support seat 11 is a longitudinal beam structure extending along the length direction of the left longitudinal beam 121 and the right longitudinal beam 122. The left longitudinal beam 121 and the right longitudinal beam 122 are used to connect and support the steel pipe gallery 40. The front cross beam 123 and the rear cross beam 124 are located at the top of the left longitudinal beam 121 and the right longitudinal beam 122, and the two ends of the front cross beam 123 and the rear cross beam 124 are fixedly connected to the left longitudinal beam 121 and the right longitudinal beam 122 respectively. The jacking mechanism 13 is provided with two groups, the bottoms of the two groups of jacking mechanisms 13 are connected to the lower support seat 11, and the tops of the two groups of jacking mechanisms 13 are connected to the middle longitudinal beam 125, so as to lift the left longitudinal beam 121, the right longitudinal beam 122, the front cross beam 123 and the rear cross beam 124 together.

[0062] In some alternative embodiments: See Figures 1 to 3 As shown, the embodiment of the present application provides a large steel pipe gallery mobile jacking device, the jacking mechanism 13 of the large steel pipe gallery mobile jacking device includes a multi-stage jacking oil cylinder 131, and the multi-stage jacking oil cylinder 131 is provided with two groups and is symmetrically arranged at the two ends of the middle longitudinal beam 125 and is respectively fixedly connected to the front cross beam 123 and the rear cross beam 124. The fixed end of the multi-stage jacking oil cylinder 131 is connected to the lower support seat 11, and the telescopic ends of the two groups of multi-stage jacking oil cylinders 131 are respectively connected to the two ends of the middle longitudinal beam 125.

[0063] The lifting mechanism 13 also includes a multi-stage guide column 132, which is connected to each other by sliding and telescopic connection of a multi-section guide sleeve. The bottom of the multi-stage guide column 132 is connected to the lower support seat 11, and the top of the multi-stage guide column 132 is connected to the telescopic end of the multi-stage lifting cylinder 131 through a connecting plate. There are two groups of multi-stage guide columns 132, which are respectively located on the sides of the two groups of multi-stage lifting cylinders 131. The two groups of multi-stage guide columns 132 provide vertical telescopic guidance for the two groups of multi-stage lifting cylinders 131, and enhance the bending moment of the multi-stage lifting cylinders 131.

[0064] The multi-stage guide column 132 and the multi-stage lifting cylinder 131 form a lifting mechanism 13 that expands and contracts in a direction perpendicular to the ground plane, playing a key role in lifting the steel pipe gallery 40. The multi-stage guide column 132 plays a guiding role in the direction perpendicular to the ground plane. When the multi-stage lifting cylinder 131 expands and contracts, the multi-stage guide column 132 and the multi-stage lifting cylinder 131 move synchronously. Since the multi-stage lifting cylinder 131 cannot bear lateral loads, after the multi-stage lifting cylinder 131 is extended, the multi-stage guide column 132 plays a role in bearing bending moment and guiding.

[0065] In some alternative embodiments: See Figures 1 to 4As shown, the embodiment of the present application provides a large-scale steel pipe gallery mobile jacking device, and both ends of the left longitudinal beam 121 and the right longitudinal beam 122 of the large-scale steel pipe gallery mobile jacking device are slidably connected with telescopic longitudinal beams 126. The left longitudinal beam 121 and the right longitudinal beam 122 are both provided with a first horizontal jacking mechanism for driving the telescopic longitudinal beam 126 to telescope, and the first horizontal jacking mechanism is preferably but not limited to a hydraulic cylinder. The end of each telescopic longitudinal beam 126 away from the left longitudinal beam 121 and the right longitudinal beam 122 is provided with a balancing oil top 127 for supporting the steel pipe gallery 40 and an anchor 129 connecting the steel pipe gallery 40.

[0066] In the embodiment of the present application, both ends of the left longitudinal beam 121 and the right longitudinal beam 122 are slidably connected with telescopic longitudinal beams 126, and the telescopic longitudinal beams 126 can adjust the lengths of the left longitudinal beam 121 and the right longitudinal beam 122 by telescopic movement in the left longitudinal beam 121 and the right longitudinal beam 122. The first horizontal pushing mechanism is fixed in the left longitudinal beam 121 and the right longitudinal beam 122, and the first horizontal pushing mechanism can synchronously push the telescopic longitudinal beams 126 to move in directions approaching or moving away from each other. The first horizontal pushing mechanism can also synchronously push the telescopic longitudinal beams 126 at both ends of the left longitudinal beam 121 and the right longitudinal beam 122 to synchronously telescopically move in the same direction, so as to achieve precise longitudinal alignment of the steel pipe gallery 40.

[0067] Each telescopic longitudinal beam 126 is provided with a balancing oil top 127 for supporting the steel pipe gallery 40 at one end away from the left longitudinal beam 121 and the right longitudinal beam 122. The balancing oil top 127 is mainly used to support the steel pipe gallery 40. When the steel pipe gallery support frame 12 supports the steel pipe gallery 40, the supporting point of the steel pipe gallery support frame 12 adopts the balancing oil top 127 to support the steel pipe gallery 40, and the balancing oil top 127 is passively loaded. By presetting the supporting force range of the balancing oil top 127, when the pressure exceeds the maximum value, the balancing oil top 127 overflows, and when the pressure is lower than the minimum value, the accumulator replenishes oil to the balancing oil top 127 to ensure that the steel pipe gallery 40 is not damaged. The balancing oil top 127 is set to detect the position and pressure, and the ultra-high pressure passive overflow and ultra-low pressure active oil replenishment methods are used to control the force of each supporting point of the steel pipe gallery 40 within the design range.

[0068] In some alternative embodiments: See Figures 1 to 4As shown, the embodiment of the present application provides a large-scale steel pipe gallery mobile jacking device, the two ends of the front crossbeam 123 and the rear crossbeam 124 of the large-scale steel pipe gallery mobile jacking device are respectively fixedly connected to the left longitudinal beam 121 and the right longitudinal beam 122, and the lower support seat 11 is provided with a second horizontal jacking mechanism 128 that synchronously drives the left longitudinal beam 121, the right longitudinal beam 122, the left longitudinal beam 123 and the right longitudinal beam 124 to synchronously reciprocate along the width direction of the middle longitudinal beam 125. The second horizontal jacking mechanism 128 is preferably, but not limited to, a hydraulic cylinder. The second horizontal jacking mechanism 128 pushes the left longitudinal beam 121 and the right longitudinal beam 122 to move in the direction close to or away from the lower support seat 11 through its own telescopic movement, so as to realize the precise lateral alignment of the steel pipe gallery 40.

[0069] In some alternative embodiments: See Figures 1 to 4 As shown, the embodiment of the present application provides a large-scale steel pipe gallery mobile jacking device, and the jacking assembly transport vehicle of the large-scale steel pipe gallery mobile jacking device also includes a flatbed transport vehicle 20 for moving the steel pipe gallery jacking assembly 13 to a set work station.
