Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a large equipment frame jacking device and sliding method. Background Technology

[0002] In the jacking and sliding construction of large equipment or heavy-tonnage structures, the jacking cylinder serves as the core actuator, providing forward thrust. However, existing technologies often face risks such as poor synchronization among multiple cylinders and uneven thrust leading to stress concentration or displacement of components, especially prominent in large-tonnage, long-distance projects. The accompanying jacking pump station, as the power source, suffers from insufficient pressure and flow control accuracy and lag in multi-cylinder coordinated response, making it difficult to accurately guarantee synchronous jacking.

[0003] Meanwhile, the locking reliability and response speed of the rail clamps are crucial. Existing rail clamps often suffer from insufficient clamping force, sluggish action, poor coordination with the jacking cylinder, and low automation, requiring frequent manual intervention and posing safety hazards. Overall, existing jacking systems are inadequate in terms of efficient and reliable coordinated control between the cylinder, pump station, and rail clamps, thus hindering construction efficiency and safety.

[0004] Therefore, it is necessary to propose a large equipment frame jacking device and sliding method to address the above problems. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a large equipment frame jacking device and sliding method to solve the above problems.

[0006] A large equipment frame jacking device includes a support mechanism, a jacking mechanism, and a monitoring mechanism. The jacking mechanism and the monitoring mechanism are both mounted on the support mechanism, and the jacking mechanism is connected to the monitoring mechanism.

[0007] Preferably, the support mechanism includes columns, a lower bracket, a crossbeam, and a roadbed plate. The columns are mounted on the lower bracket, the lower bracket is mounted on the roadbed plate, and the crossbeam is located between the two columns.

[0008] Preferably, the crossbeam includes a leg crossbeam and a Bailey beam, the leg crossbeam being connected between the bottoms of the two columns, and the Bailey beam being connected between the middle parts of the two columns.

[0009] Preferably, the roadbed plate includes a steel plate and a rail, with the rail disposed on the steel plate.

[0010] Preferably, the jacking mechanism includes a jacking cylinder, a rail clamp, a first connecting steel plate, and a second connecting steel plate. The two ends of the jacking cylinder are respectively hinged to the first connecting steel plate and the second connecting steel plate. The first connecting steel plate is fixed to the rail clamp, and the second connecting steel plate is fixed to the lower bracket. The rail clamp is installed on the rail.

[0011] Preferably, both the first connecting steel plate and the second connecting steel plate are provided with reinforcing ribs.

[0012] Preferably, the jacking mechanism further includes a jacking pump station, which is located between the two support leg beams and is connected to the jacking cylinder.

[0013] Preferably, the monitoring mechanism includes a control box and a network bridge, the control box being electrically connected to the network bridge and the jacking pump station respectively, and the jacking pump station being connected to the jacking cylinder via a hydraulic hose.

Install the support mechanism, lay four road plate slabs in parallel, set two lower brackets at intervals on every two road plate slabs, the four lower brackets are distributed in parallel and symmetrically, and install columns on each of the four lower brackets. Along the direction of the road plate slab, connect the support leg beam between the bottom of the two columns, and connect the Bailey beam in the middle of the two columns 11. S2. Install the jacking mechanism and monitoring mechanism. Four jacking cylinders are set at the lower bracket at the front end along the sliding direction. The four jacking cylinders are distributed on the steel rails of the four track plates. One end of each jacking cylinder is connected to the lower bracket, and the other end of each jacking cylinder is connected to the rail clamp.

The control box is electrically connected to the network bridge and the jacking pump station. The jacking pump station and the jacking cylinder are connected by hydraulic hoses. S3. During the jacking process, after the control box issues the jacking command, the rail clamp clamps the rails on the roadbed plate, grease is applied to the rails, and a jacking stroke begins. The jacking cylinder pushes the lower bracket in the sliding direction, thereby driving the front column to slide forward. The front column drives the rear column to slide through the support leg beam. After one stroke is completed, the control box issues a release oil circuit command, the rail clamp opens, and the jacking cylinder drives the rail clamp to begin retracting. After completion, the previous command is repeated to achieve fully automated and efficient jacking and sliding.

The support legs of the crossbeams and Bailey beams enhance the rigidity and versatility of the support, while the steel plates and rails of the roadbed plates distribute the load and ensure smooth movement. The jacking mechanism's jacking cylinders are detachably connected to the connecting steel plates via ear plates, high-strength bolts, and rail clamps, ensuring precise positioning. The reinforced ribs enhance connection stability, and the jacking pump station provides stable hydraulic power and makes efficient use of space.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0022] like Figure 1 and combined Figures 2 to 6 As shown, a large equipment frame jacking device includes a support mechanism 1, a jacking mechanism 2, and a monitoring mechanism 3. The jacking mechanism 2 and the monitoring mechanism 3 are both mounted on the support mechanism 1, and the jacking mechanism 2 is connected to the monitoring mechanism 3.

[0023] Furthermore, the support mechanism 1 includes a column 11, a lower bracket 12, a crossbeam 13, and a roadbed 14. The column 11 is mounted on the lower bracket 12, the lower bracket 12 is mounted on the roadbed 14, and the crossbeam 13 is located between the two columns 11.

[0024] The following benefits are derived from the adoption of further technical solutions: The column 11 is installed on the lower bracket 12, which is laid on the roadbed plate 14. This allows the load generated by the jacking operation to be evenly transferred to the column 11 through the lower bracket 12, dispersing the local stress and preventing damage to the roadbed or installation surface. The crossbeam 13 connects the two columns 11, effectively enhancing the overall rigidity and deformation resistance of the support mechanism 1, preventing the column 11 from tilting or swaying when subjected to jacking force, further improving the load-bearing stability of the support mechanism 1, and providing a solid guarantee for the stable operation of the jacking mechanism 2.

[0025] Furthermore, the crossbeam 13 includes a leg crossbeam 131 and a Bailey beam 132. The leg crossbeam 131 is connected between the bottoms of the two columns 11, and the Bailey beam 132 is connected between the middle parts of the two columns 11.

[0026] The following benefits are derived from the adoption of further technical solutions: The support beam 131 connects the bottom of the two columns 11, which can strengthen the connection strength of the bottom of the columns 11, prevent the bottom of the columns 11 from shifting under force, and improve the bottom stability of the support mechanism 1; The Bailey beam 132 connects the middle of the two columns 11. By utilizing the high strength, light weight and convenient disassembly and assembly of the Bailey beam 132, the rigidity of the middle of the support mechanism 1 is further enhanced, effectively resisting the lateral force and bending moment generated during the jacking operation, and avoiding the deformation of the middle of the support mechanism 1. At the same time, the setting of the Bailey beam 132 also makes it easy to adjust the support span according to the actual jacking requirements, thereby improving the versatility of the device.

[0027] Furthermore, the roadbed plate 14 includes a steel plate 141 and a rail 142, with the rail 142 disposed on the steel plate 141.

[0028] The benefits of adopting further technical solutions are as follows: the steel plate 141 can increase the contact area between the roadbed plate 14 and the ground, further disperse the jacking load, and avoid uneven ground pressure leading to settlement; the steel rail 142 can reduce the frictional resistance between the lower bracket 12 and the roadbed plate 14, making it easier for the support mechanism 1 to drive the large equipment frame to move smoothly during the jacking process. At the same time, the steel rail 142 has excellent wear resistance and compressive strength, which can extend the service life of the roadbed plate 14, reduce equipment maintenance costs, and ensure the smoothness of the jacking operation.

[0029] Furthermore, the jacking mechanism 2 includes a jacking cylinder 21, a rail clamp 22, a first connecting steel plate 23, and a second connecting steel plate 24. The two ends of the jacking cylinder 21 are respectively hinged to the first connecting steel plate 23 and the second connecting steel plate 24. The first connecting steel plate 23 is fixed to the rail clamp 22, and the second connecting steel plate 24 is fixed to the lower bracket 12. The rail clamp 22 is installed on the rail 142.

[0030] The advantages of adopting further technical solutions are as follows: the jacking cylinder 21 in the jacking mechanism 2 is detachably connected to the rail clamp 22 and the first connecting steel plate 23 and the second connecting steel plate 24 on the lower bracket 12, and the connection method is firm and reliable; the rail clamp 22 can realize positioning and locking during the jacking process, prevent the jacking mechanism 2 from slipping, and ensure that the jacking displacement is accurate and controllable.

[0031] Furthermore, both the first connecting steel plate 23 and the second connecting steel plate 24 are provided with reinforcing ribs 26.

[0032] The benefits of adopting further technical solutions are as follows: strengthening the rib plate 26 can effectively enhance the structural strength of the welded parts, disperse the stress concentration at the welded parts, and avoid problems such as weld cracking and falling off due to repeated stress on the first connecting steel plate 23 and the second connecting steel plate 24 during the jacking operation. It further improves the stability and firmness of the connection between the components of the jacking mechanism 2, and ensures that the jacking force transmitted by the jacking cylinder 21 can act on the large equipment frame efficiently and stably, thus ensuring the safe and orderly conduct of the jacking operation.

[0033] Furthermore, the jacking mechanism 2 also includes a jacking pump station 27, which is located between the two support beams 131 and is connected to the jacking cylinder 21 via a hydraulic hose.

[0034] The advantages of adopting a further technical solution are as follows: The jacking pump station 27 is installed between the two support leg beams 131, which is a reasonable layout and can make full use of the space of the support mechanism 1, avoiding the occupation of additional working space; The jacking pump station 27 is connected to the jacking cylinder 21, which can provide stable hydraulic power to the jacking cylinder 21, accurately control the extension and retraction speed and jacking force of the jacking cylinder 21, and realize the smooth and precise jacking of the large equipment frame. At the same time, the jacking pump station 27 is installed between the support leg beams 131 and can be protected by the support mechanism 1, reducing damage caused by external collisions, dust and other factors, and extending the service life of the jacking pump station 27.

[0035] Furthermore, the monitoring mechanism 3 includes a control box 31 and a network bridge 32. The control box 31 is electrically connected to the network bridge 32 and the jacking pump station 27, respectively. The jacking pump station 27 is connected to the jacking cylinder 21 through a hydraulic hose.

[0036] The benefits of adopting further technical solutions are as follows: the control box 31 can adjust the operating parameters of the jacking cylinder 21 in real time through the jacking pump station 27, thereby realizing automated control of the jacking operation and reducing the intensity of manual operation; the network bridge 32 can realize stable transmission of control signals, ensuring smooth signal between the control box 31 and the jacking mechanism 2, and avoiding loss of control of the jacking operation due to signal interruption; at the same time, the control box 31 can collect the operating data of the jacking cylinder 21 and the jacking pump station 27 in real time, and transmit it to the back-end terminal through the network bridge 32, so that the staff can monitor the status of the jacking operation in real time, discover and deal with abnormal problems in a timely manner, and further improve the safety, controllability and intelligence level of the jacking operation.

The control box 31 is electrically connected to the network bridge 32 and the jacking pump station 27. The jacking pump station 27 is connected to the jacking cylinder 21 through a hydraulic hose. S3.

The jacking cylinder 21 pushes the lower bracket 12 in the sliding direction, thereby driving the front column 11 to slide forward. The front column 11 drives the rear column 11 to slide through the support leg beam 131. After one stroke is completed, the control box 31 issues the release oil circuit command, the rail clamp 22 opens, and the jacking cylinder 21 drives the rail clamp 22 to begin to retract. After completion, the previous command is repeated to achieve fully automated and efficient jacking and sliding.

[0038] Compared with the prior art, the present invention has the following advantages: In the support mechanism 1, the column 11, lower bracket 12, crossbeam 13 and roadbed 14 cooperate with each other to provide a stable bearing foundation for the overall device. The support beam 131 and Bailey beam 132 of the crossbeam 13 enhance the support rigidity and versatility. The steel plate 141 and rail 142 of the roadbed 14 distribute the load and ensure smooth movement.

The various mechanisms work together, simplifying the structure and facilitating maintenance, which greatly improves the safety, controllability and intelligence level of the jacking operation of large equipment frames.

[0040] Example 1: Jacking Construction of Large Bridge Steel Box Girder This embodiment is applied to the jacking construction of a large bridge steel box girder with a span of 50m and a weight of 800t. The construction site is a flat road section, and the foundation bearing capacity has been treated to reach 250kPa. The total jacking distance is 300m. The large equipment frame jacking device and sliding method of this invention are used. The specific implementation process is as follows: 1. Support Structure Installation: Four roadbed plates, each measuring 6m × 1.2m × 0.08m, are selected. The steel plates are made of Q355B material, and the rails are P50 heavy rails. They are laid parallel to each other on the treated foundation at a spacing of 4.5m. Two lower supports are installed at 8m intervals on every two roadbed plates. The lower supports are welded from structural steel and measure 2m × 1.8m × 0.5m. The four lower supports are arranged in a parallel and symmetrical manner. Uprights are installed on each of the four lower supports. The uprights are made of seamless steel pipe with a height of 6m and a diameter of Φ630×16mm. Along the length of the roadbed plate, a support beam (H-beam, H400×200×8×12) is connected between the bottom of two uprights. A Bailey beam, made of 321 type, is connected between the two uprights (3m from the bottom). Each section of the Bailey beam is 3m long and spliced ​​together to a length of 8m according to the support span to ensure the overall rigidity of the support structure.

[0041] 2. Installation of the jacking mechanism and monitoring mechanism: Four jacking cylinders are installed at the lower bracket at the front end of the sliding direction. Double-acting cylinders of model HSG125 / 70-1200 are selected, with a rated thrust of 1200kN and a stroke of 1200mm. The four jacking cylinders are evenly distributed on the rails of the four track plates. Each jacking cylinder is connected at both ends to a first connecting steel plate and a second connecting steel plate via hinges. The connecting steel plates are made of 20mm thick Q355B steel plates, each welded with reinforcing ribs (16mm thick, 300mm×200mm). The first connecting steel plate is bolted to a rail clamp (model JGQ-20, clamping force 200kN), and the second connecting steel plate is welded to the lower bracket. The rail clamp is mounted on the rail and its tightness is adjusted. Two jacking pump stations are installed between the two support beams near the jacking cylinders. CB-KP200 hydraulic pump stations with a rated pressure of 31.5 MPa are selected. Each jacking pump station is connected to two jacking cylinders via hydraulic hoses to achieve synchronous oil supply. The control box of the monitoring mechanism uses a PLC control cabinet (model S7-1200), and the network bridge is an industrial-grade wireless network bridge (transmission distance ≥500m). The control box is electrically connected to the network bridge and the jacking pump stations to collect real-time data on jacking cylinder pressure, displacement, and rail clamp status.

[0042] 3. Jacking and Sliding Construction: Following the sliding method described in the invention, after completing steps S1 and S2, equipment debugging is performed to ensure normal operation of each mechanism. During the jacking process in S3, the control box issues a jacking command, the rail clamp quickly clamps the rail (response time ≤0.5s), grease is applied to the rail surface to reduce frictional resistance, and the jacking cylinder pushes the lower support frame in the sliding direction at a speed of 50mm / min, moving the front column forward. The front column, through the support leg beam, pulls the rear column to slide synchronously. The single jacking stroke is 1200mm, the thrust is controlled between 800-1000kN, and the synchronization error of multiple cylinders is ≤3mm. After one stroke, the control box issues a release command, the rail clamp opens, and the jacking cylinder retracts at a speed of 80mm / min. After retraction, the jacking process is repeated. The entire process is automated and requires no manual intervention. During construction, the operating status of each component was monitored in real time through the control box, and the network bridge stably transmitted signals to ensure a smooth jacking process. After 600 jacking strokes, the 300m steel box girder was jacked up with a jacking deviation of ≤5mm. There were no problems such as stress concentration or displacement of components, and the construction efficiency was improved by more than 30% compared with the traditional jacking method.

[0043] Example 2: Construction of Steel Roof Truss Jacking for Large Factory Buildings This embodiment is applied to the jacking construction of a large factory steel roof truss with a span of 36m and a weight of 350t. The construction site is an industrial plant area with a foundation bearing capacity of 200kPa. The total jacking distance is 120m. The steel roof truss is assembled in sections and then jacked as a whole. The device and method of this invention are used, and the specific implementation process is as follows: 1. Support Structure Installation: Four roadbed plates, each measuring 5m × 1.0m × 0.06m, are selected. The steel plates are made of Q235B steel, and the rails are P43 type. They are laid parallel to each other on the hardened ground of the factory area at a spacing of 3.8m. Two lower brackets, each measuring 1.8m × 1.5m × 0.4m, are installed at 6m intervals on every two roadbed plates. These lower brackets are welded from structural steel sections, and the four lower brackets are arranged in a parallel and symmetrical manner. The uprights are made of Φ530×14mm seamless steel pipes, with a height of 5m. A support beam (H-beam, H350×175×7×11) is connected between the bottom of two uprights, and a 321 type Bailey beam is connected in the middle (2.5m from the bottom). The splicing length is 6m, which is suitable for the steel roof truss support requirements and enhances the deformation resistance of the support structure.

[0044] 2. Installation of the jacking mechanism and monitoring mechanism: Four jacking cylinders are installed at the lower bracket at the front end of the sliding direction. These are double-acting cylinders, model HSG100 / 63-1000, with a rated thrust of 800kN and a stroke of 1000mm, evenly distributed on the four rails. The first and second connecting steel plates are made of 16mm thick Q235B steel plates, with welded reinforcing ribs (14mm thick, 250mm×180mm). The two ends of the jacking cylinders are hinged together. The first connecting steel plate is fixed to the rail clamp (model JGQ-15, clamping force 150kN), and the second connecting steel plate is fixed to the lower bracket. The rail clamp is installed on the rails, and its locking reliability is tested. Two jacking pump stations (model CB-KP160, rated pressure 25MPa) are installed between the support leg beams near the jacking cylinders. Each pump station connects to two jacking cylinders to ensure stable hydraulic power. The control box of the monitoring unit uses a PLC control cabinet, and the network bridge uses an industrial wireless network bridge. The control box is electrically connected to the jacking pump station and the network bridge to monitor the jacking speed, cylinder pressure and rail clamp operation status in real time. In case of abnormality, the machine can automatically stop and alarm.

[0045] 3. Jacking and Sliding Construction: After completing the sliding steps described in the invention and the installation and debugging of S1 and S2, the jacking operation begins. During S3, the control box issues a jacking command, the rail clamps quickly clamp the rails, grease is applied to the rail surface to reduce friction, and the jacking cylinders push the lower support frame at a speed of 40mm / min, moving the columns and steel roof trusses forward. The single jacking stroke is 1000mm, the thrust is controlled between 350-450kN, and the synchronization error of multiple cylinders is ≤2mm. After one stroke, the rail clamps release, the jacking cylinders retract, and the jacking process is repeated after retraction. The entire operation is automated, and the operator only needs to monitor the operating data in the background. During construction, the support structure is stable, without tilting or deformation, the jacking pump station pressure is stable, and the rail clamps move in a coordinated manner without slippage. After 120 jacking strokes, the 120m steel roof truss was jacked up with a jacking deviation of ≤4mm. The construction was safe and reliable. Compared with the traditional manual jacking method, it greatly reduced the labor intensity, reduced safety hazards, and shortened the construction period by 25%.

9. A sliding method for a large equipment frame jacking device as described in any one of claims 1-8, characterized in that: The method and steps are as follows: S1. Install support mechanism (1), lay four road plate slabs (14) in parallel, and set two lower brackets (12) at intervals on each two road plate slabs (14). The four lower brackets (12) are distributed in parallel and symmetrically. A column (11) is installed on each of the four lower brackets (12). Along the direction of the road plate slab (14), a support beam (131) is connected between the bottom of the two columns (11), and a Bailey beam (132) is connected in the middle of the two columns (11). S2. Install the jacking mechanism (2) and the monitoring mechanism (3). Set four jacking cylinders (21) at the lower bracket (12) at the front end along the sliding direction. The four jacking cylinders (21) are distributed on the rails (142) of the four roadbed plates (14). One end of each jacking cylinder (21) is connected to the lower bracket (12), and the other end of each jacking cylinder (21) is connected to the rail clamp (22). Set two jacking pump stations (27) between the two support beams (131) near the jacking cylinder (21). Each jacking pump station (27) is connected to two jacking cylinders (21). The control box (31) is electrically connected to the network bridge (32) and the jacking pump station (27). The jacking pump station (27) and the jacking cylinder (21) are connected by hydraulic hoses. S3. During the jacking process, after the control box (31) issues the jacking command, the rail clamp (22) clamps the rail (142) of the road plate (14), grease is applied to the rail (142), and a jacking stroke begins. The jacking cylinder (21) pushes the lower bracket (12) in the sliding direction, thereby driving the column (11) in front to slide forward. The column (11) in front drives the column (11) in the back to slide through the support leg beam (131). After a stroke is completed, the control box (31) issues the release oil circuit command, the rail clamp (22) opens, and the jacking cylinder (21) drives the rail clamp (22) to start retracting. After completion, the previous command is repeated to achieve fully automated and efficient jacking and sliding.
