Description

Technical Field

[0001] This invention belongs to the field of large building translation technology, specifically relating to a split-type sliding device and translation method for heavy-duty silos. Background Technology

[0002] Silos are structures for storing bulk materials, and can be broadly classified into agricultural silos and industrial silos according to their use. Agricultural silos are used to store granular and powdery materials such as grains and feed; industrial silos are used to store bulk materials such as coke, cement, salt, and sugar. According to materials, they are classified into reinforced concrete silos, steel silos, and brick silos. Considering economic and durability factors, the most widely used type in engineering is the monolithically cast ordinary reinforced concrete silo. A typical ordinary reinforced concrete silo includes a roof, walls, supporting structure (walls or columns), and bottom. For silos with a diameter greater than 12m, a ground-mounted structure is recommended. The heavy-duty silo to be moved in this invention is a coal mine storage silo. "Heavy-duty" refers to a single-point load exceeding 1000t. Due to production development needs, it requires overall relocation, i.e., the bottom is cut and the entire silo is moved.

[0003] Building relocation technology has a history of over 100 years. As early as the 1990s, my country successfully relocated many buildings of different structural forms. The specific method involves completely separating the building from its original foundation and then using a whole-unit replacement to create a movable whole, which is then moved from its original site to a new site by a relocation device. Common relocation methods include rolling and sliding, and the directions of movement include longitudinal, lateral, turning, and a combination of movement and turning. Commonly used relocation devices include track-type (translational or rolling) relocation devices, walking-type jacking devices, and SPMT (Special Purpose Vehicle) whole-unit relocation. However, based on the structural characteristics of the raw coal bunker, the load is mainly transmitted along the cylinder wall, and the load is analyzed in a circular manner, making it impossible to use existing relocation devices.

[0004] Cases of using the overall translation technology for heavy-duty silos with a height-to-width ratio greater than 2 are rare, and there are no cases of using the overall translation method to relocate raw coal silos, either domestically or internationally. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a split sliding device and its sliding method for heavy-duty silo relocation. It adopts a single-point support slide box and lightweight matching slide rail, which is convenient for on-site implementation in small installation spaces and has the characteristics of low friction coefficient, reduced traction force for relocation, and improved relocation construction efficiency. It is suitable for heavy-duty long-stroke relocation.

[0006] A split-type sliding device for translating heavy-duty silos includes a sliding box, a sliding groove, a vertical lifting device, and a horizontal pulling device; the sliding box is placed on the sliding groove and can slide along the sliding groove, and the coefficient of friction of the contact surface between the two is as small as possible;

[0007] Both the vertical lifting device and the horizontal pulling device are connected to the sliding box. The other end of the horizontal pulling device is connected to a steel rod and a horizontal traction jack. The horizontal traction jack is supported on the reaction pier. The top of the vertical lifting device supports the heavy-duty silo to be moved.

[0008] Under the horizontal pulling force provided by the horizontal pulling device, the sliding box drives the heavy-duty silo above the sliding box to slide along the sliding groove, thus realizing translation.

[0009] A lower track beam is cast between the old and new silo locations, and a chute is laid on the lower track beam. The upper surface of the chute is covered with a mirror-finished stainless steel plate. The chute is designed as one or more chute units, which can be reused during the silo's relocation process. The chute units are joined together with tongue and groove joints to ensure that the chute can slide smoothly through the joints.

[0010] The vertical jacking device and the horizontal traction device are set up separately. Specifically, the sliding box and the vertical jacking device are installed together with the silo and move together with the silo during the translation process; the horizontal traction device is installed on the concrete reaction pier outside the silo and its position does not move during the translation process. Placing the horizontal traction device outside the silo facilitates the adjustment of the length of the connecting steel bar, the synchronous control of the horizontal traction jacks, and the monitoring of whether multiple tracks are synchronized during the translation process. In addition, a split sliding device is adopted, with the jacking load control box and the traction load control box set up in different locations, which can ensure the accuracy of manual operation during construction and avoid the construction safety risks caused by misoperation.

[0011] The vertical lifting device includes: a vertical lifting jack and a lifting load control box; wherein, the assembly sequence of the vertical lifting device is as follows: the chute is laid outside the silo to leave space for the sliding box to be hoisted → the sliding box is hoisted and placed in the chute → the vertical lifting jack is hoisted → the sliding box is horizontally pulled to the lifting point → the oil pipe of the vertical lifting jack is connected to the lifting load control box. After the vertical lifting device is assembled, the lifting load control box is started to realize the lifting and support of the silo.

[0012] The horizontal traction device includes: a connecting steel bar, a concrete reaction pier, a horizontal traction jack, and a traction load control box; wherein, one end of the connecting steel bar is connected to the sliding box, and the other end passes through the concrete reaction pier and connects to the horizontal traction jack; the concrete reaction pier is located at the end of the lower track beam of the silo translation, is cast together with the lower track beam and is located outside the silo, and can reliably provide support for the horizontal traction jack; the assembly sequence of the horizontal traction device is as follows: the vertical jacking device is completed → the connecting steel bar is installed → the connecting steel bar passes through the concrete reaction pier → the horizontal traction jack is installed → the oil pipe of the horizontal traction jack is connected to the traction load control box. After the horizontal traction device is assembled, the traction load control box is started. Under the drive of the horizontal traction jack, the connecting steel bar pulls the sliding box to move along the slide, thereby driving the silo to move.

[0013] The sliding box is welded from steel plates to ensure reliable transmission of vertical lifting load and horizontal traction force. Connecting steel rod anchor blocks are installed at both ends of the sliding box to ensure that multiple sliding boxes can be connected in series on the same sliding track. The middle area of ​​the sliding box is divided into upper and lower sections. The upper section is the installation area for the vertical lifting jacks, and the lower section is the installation area for the MGB plate. The height of the upper section steel plate in the middle area of ​​the sliding box should be less than the height of the vertical lifting jacks to ensure that the entire lifting load is borne by the vertical lifting jacks. The upper section steel plate is equipped with mounting holes for the jack grease fittings. The height of the lower section steel plate in the middle area of ​​the sliding box should be less than the thickness of the MGB plate. The MGB plate is embedded in the lower section of the middle area of ​​the box and protrudes ≥10mm from the sliding box body. This ensures that the MGB plate slides together with the sliding box body and that the contact surface between the sliding box and the sliding track is only the contact between the MGB plate and the mirror-finished stainless steel.

[0014] The horizontal traction device is symmetrically arranged in two sets to prevent large swings of the slide box when pulled at a single point.

[0015] The section where the connecting steel bar passes through the concrete reaction pier is equipped with a pre-embedded steel pipe sleeve.

[0016] The sliding device is no more than 500mm high and is installed under the main load-bearing wall column of the heavy-duty silo. A follow-up horizontal sliding device is arranged at the center of the silo plane to ensure the safety of the upper track beam during sliding.

[0017] The heavy-duty silo translation and sliding process based on a split-type sliding device for heavy-duty silo translation includes the following steps:

[0018] (1) Casting the upper and lower track beams for translation and the stress transfer ring beam at the bottom of the silo wall;

[0019] (2) Once the strength of the upper and lower track beams and the load transfer beams meets the requirements, cut the concrete between the upper and lower tracks on the silo wall and set up temporary supports simultaneously;

[0020] (3) Lay a chute on the top surface of the lower track beam, use hoisting machinery to hoist the sliding box on the outside of the silo, and install the sliding box on the chute;

[0021] (4) Hoist the vertical lifting jack into the sliding box, but do not install the oil pipe for the time being;

[0022] (5) Horizontally pull the sliding box to the jacking point below the silo wall column, connect the vertical jacking jack and the jacking load control box, start the jacking load control box, complete the jacking and replacement of the silo and remove all temporary supports;

[0023] (6) Install the horizontal traction connecting steel bar and the horizontal traction jack, and connect the horizontal traction jack to the traction load control box;

[0024] (7) Start the traction load control box to realize the horizontal movement of the silo;

[0025] During the silo relocation process, a sliding groove is used to ensure that the sliding surface is the contact surface between the MGB plate and the stainless steel mirror plate.

[0026] Because the installation space between the upper and lower tracks is narrow, no more than 500mm, it is impossible to use hoisting machinery to lift the relatively heavy sliding box and jacks; therefore, the sliding box is hoisted from the outside of the silo after the sluice is laid and pulled to the lower part of the silo, while the jacks are placed directly outside the silo for easy installation and control.

[0027] Since the heavy-duty silo has a circular plan and the main force is transmitted directly along the silo wall, a horizontal sliding device is installed on the main load-bearing columns of the silo wall. Considering the large span of the heavy-duty silo, a follow-up horizontal sliding device is generally arranged at the center of the silo plan to ensure the safety of the upper track beam during sliding.

[0028] Requirements for the horizontal sliding device:

[0029] (1) It is necessary to consider the load-bearing requirements of more than 1200 tons, but the load-bearing area of ​​the sliding box should not be too large and the height of the entire sliding device should not exceed 500mm to avoid instability of the heavy-duty silo during the translation process.

[0030] (2) The coefficient of friction between the sliding box and the sliding groove should be as small as possible. In this invention, the bottom surface of the sliding box is an embedded MGB plate, and the compressive bearing capacity of the MGB plate is required to be greater than 30MPa; the sliding groove is covered with a 2mm thick mirror stainless steel plate. The above measures can ensure that the coefficient of friction of the sliding surface is not greater than 0.08.

[0031] A limiting device is installed between the sliding box and the sliding chute to prevent the heavy-load silo from swaying too much during the translation process.

[0032] Connecting screw anchor blocks are installed at both the front and rear of the sliding box to ensure that multiple sliding boxes can be connected in series on the same sliding track.

[0033] Beneficial effects

[0034] (1) The silos that are moved by this invention have the characteristics of large overall weight, high height and obvious force transmission characteristics of the cylinder wall. The operating space between the upper and lower track beams is limited, and the allowable load-bearing capacity of the moving equipment needs to be considered. The split sliding device provided by this invention is suitable for heavy-duty silos and has small installation space requirements. With the matching lightweight slide rail, it can realize the manual installation and correction of the existing silo lower slide rail, and can be reused and save costs.

[0035] (2) This invention is designed for the characteristics of silos. It uses a single-point supported sliding box and a lightweight matching sliding rail for overall translation. This facilitates manual installation under the existing silos and enables rapid connection and installation of multiple sliding boxes on a single rail. At the same time, the sliding surface structure between the sliding box and the sliding rail facilitates on-site implementation and has a low coefficient of friction, reducing the translation traction force and improving the translation construction efficiency.

[0036] (3) By using the method and apparatus of the present invention, the amount of engineering equipment can be greatly reduced, the difficulty of construction synchronization control can be reduced, the number of personnel in the translation construction stage can be reduced, the construction period of the entire translation can be shortened, and the project cost can be saved.

[0037] (4) Due to the limited operating space at the bottom of the heavy-duty silo, and considering the needs of jack hoisting and maintenance, the horizontal traction jacks need to be placed on the traction piers outside the silo. This device, which separates the traction jacks from the sliding box, is called a split-type sliding device. The horizontal traction jacks and the sliding box are connected by two high-strength steel bars. The advantage of using two steel bars is that it can prevent large swings of the sliding box when traction is applied at a single point.

[0038] (4) The sliding box needs to support a single point load of 1200 tons. Four 350t lifting jacks are connected in series inside the sliding box to support the upper load. The advantages of doing so are: ① Increase the contact area between the sliding box and the silo ground; ② The height of a single 350t lifting jack is much smaller than that of a single 1200t jack, which can meet the requirement that the height of the sliding device does not exceed 500mm; ③ The weight of a single 350t lifting jack is light. Since the construction is carried out at the bottom of the silo, the lightweight equipment is convenient for workers to carry out the construction. Attached Figure Description

[0048] The technical solution of the present invention will be described below with reference to specific embodiments:

[0049] Example 1

[0050] This embodiment involves the relocation of a raw coal silo in a coal preparation plant. The silo is 55m high and 21m in diameter (height-to-width ratio greater than 2). The lower part of the silo is supported by a column-supported wall, and the top of the silo houses the raw coal conveying workshops (independent of each other). The maximum weight of a single silo is approximately 6900t. The relocation distance is approximately 150m. The overall relocation of the silo must also consider long-distance horizontal movement.

[0051] Figure 1 This is a schematic diagram showing the connection relationship between the lower track beam, the chute, and the sliding box. Figure 2 This is a three-dimensional view of the slide box. Figure 3 This is a top view of the slide box. Figure 4 This is a schematic diagram of the split-type sliding process for heavy-duty silo translation according to the present invention. Figure 5 This is a schematic diagram of the chute structure, for reference. Figure 1-5As shown, based on the arrangement of the silo wall columns, the split-type sliding device for heavy-duty silo translation provided by this invention is installed under the main load-bearing wall columns of the heavy-duty silo, and a follow-up horizontal sliding device is arranged at the center of the silo plane to ensure the safety of the upper track beam during sliding. This achieves translation support points under all main silo wall columns, with an average single-point support load of approximately 800t.

[0052] A split-type sliding device for heavy-duty silo translation is provided. It adopts a track-type design, with horizontal traction equipment installed on each sliding track, and all tracks are pulled synchronously.

[0053] Specifically, it includes upper and lower tracks; a lower track beam 5 is cast between the old and new translation positions, and a chute is laid on the lower track beam 5; the lower track is the chute. The chute is spliced ​​from multiple chute units using a chute tongue and groove joint 19. The sliding box 1 is installed on the chute 2, and a limiting device is set between the sliding box and the chute to prevent large swaying of the heavy-load silo during translation. Connecting bolt anchor blocks 3 are set at both the front and rear of the sliding box to ensure that multiple sliding boxes can be connected in series on the same sliding track.

[0054] To ensure the coefficient of friction between the sliding box and the sliding groove is minimized, this invention employs an embedded MGB plate 10 on the bottom surface of the sliding box, with a compressive strength requirement greater than 30 MPa; the sliding groove is paved with a mirror-finished stainless steel plate 4, and lubricating oil is applied to the cross-section of the MGB plate. These measures ensure that the coefficient of friction is no greater than 0.08.

[0055] The chute is manufactured using standard modules. As the sliding box moves forward, the chute is continuously reused, saving costs when the sliding distance is long. Regarding the splicing requirements of the chute: ① The ends of the side limiting steel plates of the chute need to be welded with chute connecting anchor blocks 3, and the two chute pieces are connected together using connecting bolts; ② The chute joint should use a 19mm tongue and groove joint to avoid unevenness in the track, which could lead to a height difference at the joint of the two chute pieces, causing unevenness when the sliding box passes through the joint, ultimately leading to chute failure.

[0056] The sliding box 1 has connecting steel bar mounting holes 7 on the front and rear sides. One end of the connecting steel bar 13 is connected to the sliding box 1 through the hole, and the other end passes through the concrete reaction pier 16 and is connected to the horizontal traction jack 14. The part of the connecting steel bar passing through the concrete reaction pier 16 is provided with a pre-embedded steel sleeve 15. Under the drive of the horizontal traction jack 14, the sliding box is pulled along the slide groove by the connecting steel bar, thereby driving the silo 17 to move.

[0057] The horizontal traction jacks and connecting steel bars are symmetrically arranged in two sets to prevent large swings when the slide box is pulled at a single point.

[0058] Hydraulic jacks 6 are symmetrically arranged inside the sliding box 1. In this embodiment, there are 4 jacks because the sliding box needs to support a single point load of 800 tons. The upper load is supported by 4 350t lifting jacks connected in series inside the sliding box. The advantages of doing so are: ① Increasing the contact area between the sliding box and the bottom of the silo; ② The height of a single 350t lifting jack is much smaller than that of a single 800t jack, which can meet the requirement that the height of the sliding device does not exceed 500mm; ③ The weight of a single 350t lifting jack is light. Since the construction is carried out at the bottom of the silo, the lightweight equipment is convenient for workers to construct.

[0059] Due to the limited operating space at the bottom of the heavy-duty silo, and considering the needs of jack hoisting and maintenance, the horizontal traction jack 14 needs to be placed on the traction side of the concrete reaction pier 16 outside the silo. This device, which separates the traction jack from the sliding box, is called a split-type sliding device.

[0060] The process for a split-type sliding device for heavy-duty silo relocation based on the above-mentioned split-type sliding device for heavy-duty silo relocation is as follows:

[0061] (1) Casting the upper and lower track beams for translation and the stress transfer ring beam at the bottom of the silo wall;

[0062] (2) Once the strength of the upper and lower track beams and the load transfer beams meets the requirements, cut the concrete between the upper and lower tracks on the silo wall and set up temporary supports simultaneously;

[0063] (3) Lay a chute on the top surface of the lower track beam, use hoisting machinery to hoist the sliding box on the outside of the silo, and install the sliding box on the chute;

[0064] Because the installation space between the upper and lower tracks is narrow, no more than 500mm, it is impossible to use hoisting machinery to lift the relatively heavy sliding boxes and jacks; therefore, the sliding boxes are hoisted from the outside of the silo after the sluice is laid, and then pulled to the lower part of the silo, which facilitates installation and control.

[0065] Since the heavy-duty silo is circular in plan and the main force is transmitted directly along the silo wall, a horizontal sliding device is installed under the main load-bearing wall columns of the silo.

[0066] Considering the large span of heavy-duty silos, a follow-up horizontal sliding device is usually arranged at the center of the silo plane to ensure the safety of the upper track beam during sliding.

[0067] Requirements for the horizontal sliding device:

[0068] (a) It is necessary to consider the load-bearing requirements of more than 1,200 tons, but the load-bearing area of ​​the sliding box should not be too large and the height of the entire sliding device should not exceed 500 mm to avoid instability of the heavy-duty silo during the translation process.

[0069] (b) The coefficient of friction between the sliding box and the sliding groove should be as small as possible. In this invention, the bottom surface of the sliding box is an embedded MGB plate, and the MGB plate has a compressive strength requirement of more than 30 MPa; the sliding groove is paved with mirror stainless steel plate, and the contact surface is coated with lubricating oil. The above measures can ensure that the coefficient of friction is not greater than 0.08.

[0070] (4) Hoist the 350t lifting jack into the sliding box, but do not install the oil pipe for the time being;

[0071] (5) Horizontally pull the sliding box to the jacking point below the silo wall column, connect the vertical jacking jack and the jacking load control box, start the jacking load control box, complete the jacking and replacement of the silo and remove all temporary supports;

[0072] (6) Install the horizontal traction connecting steel bar and the horizontal traction jack, and connect the horizontal traction jack to the traction load control box; the traction jack, sliding box, and connecting steel plate are located at the same level;

[0073] (7) Start the traction load control box to realize the horizontal movement of the silo;

[0074] (8) During the silo translation process, a chute is used for turnover to ensure that the sliding surface during the sliding process is the contact surface between the MGB plate and the stainless steel mirror plate.

[0075] The above description is merely a specific embodiment of this patent, but the scope of protection of this patent is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this patent should be included within the scope of protection of this patent. Therefore, the scope of protection of this patent should be determined by the scope of protection of the stated claims.
