Description

Technical Field

[0001] This utility model relates to the field of heavy building construction technology, and in particular to a long-distance displacement device for large silos. Background Technology

[0002] Large silos, as common storage structures, require overall displacement under certain circumstances (such as plant area redevelopment or equipment upgrades). Existing displacement technologies mostly employ rollers or small guide rails, which suffer from problems such as short displacement distances, poor directional control, inadequate stability, high foundation requirements, and high costs. Especially for long-distance displacements of hundreds of meters, ensuring a smooth, continuous, controllable, and cost-effective displacement process is a pressing technical challenge that needs to be addressed in this field.

[0003] However, existing methods for displacing large silos present technical challenges such as complex operation, low displacement efficiency, high frictional resistance, high risk of structural damage to the silo, and difficulty in achieving stable long-distance movement. Due to the large size and heavy weight of large silos, traditional displacement methods are prone to deformation or damage due to uneven stress. To address the shortcomings of existing technologies, the purpose of this utility model is to provide a long-distance displacement device for large silos, which aims to achieve stable, continuous, and long-distance displacement of the silos, while also possessing the advantages of structural stability, precise control, and good economy. Utility Model Content

[0004] The purpose of this invention is to provide a long-distance displacement device for large silos to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution. A long-distance displacement device for large silos includes a bottom fixing component, a track component, a box component, a lateral displacement component, a vertical lifting jack, and a silo.

[0006] The bottom fixing component serves as a basic support and is laid on the ground; the track component is laid above the bottom fixing component along the displacement direction; the box assembly is slidably supported above the track assembly by its bottom; the lateral displacement component is disposed between the box assembly and the bottom fixing component to provide power for the box assembly to move along the track assembly; the vertical lifting jack is fixedly installed inside the box assembly, and its hydraulic rod extends upward, with the top end used to support and lift the silo.

[0007] Furthermore, the bottom fixing assembly includes a base beam and a concrete reaction pier. The base beam is arranged along the extension direction of the track assembly, and the concrete reaction pier is fixedly mounted on the base beam and located at one end of the track assembly to provide robust reaction support for the lateral displacement assembly.

[0008] Furthermore, the track assembly includes a slide rail, a limiting angle steel, and anchor blocks. The slide rail is fixedly laid on the upper surface of the base beam, and the anchor blocks are fixedly connected to the corner positions of the slide rail; the limiting angle steel is arranged along the length direction of the slide rail and fixed between adjacent anchor blocks to accurately guide and limit the box assembly and prevent deviation.

[0009] As a preferred embodiment of this utility model, the front and rear ends of the slide rail are provided with tongue and groove joints, and multiple sets of slide rails are joined together along the length direction through the tongue and groove joints to form a continuous sliding track. This structure ensures that the box assembly can slide smoothly across the track joints, effectively avoiding impact and vibration at the joints, which is the key to achieving stable long-distance displacement.

[0010] As another preferred embodiment of this utility model, the slide rail is composed of a base material and a surface material. The surface material is fixedly disposed on the upper surface of the base material, and the surface friction coefficient of the surface material is lower than that of the base material. This composite structure creatively solves the contradiction between cost and performance, namely, using a high-strength base material (such as steel) to ensure structural stability, while using a low-friction surface material (such as mirror stainless steel) to reduce sliding resistance, thus combining economy and functionality.

[0011] Furthermore, the housing assembly includes a sliding box, an MGB plate, and a jack nozzle mounting hole. The MGB plate is fixedly disposed on the lower surface of the sliding box and forms a low-friction sliding pair with the upper surface of the track assembly, greatly reducing sliding resistance. The jack nozzle mounting hole is located on the side wall of the sliding box, facilitating the connection of hydraulic lines.

[0012] Furthermore, the lateral displacement assembly includes a horizontal traction jack, a precision-rolled threaded steel bar, and a threaded steel bar sleeve. The cylinder end of the horizontal traction jack is fixedly connected to the concrete reaction pier; the threaded steel bar sleeve is pre-embedded inside the concrete reaction pier; one end of the precision-rolled threaded steel bar passes through the slide box and is threadedly connected to the threaded steel bar mounting bolt, and the precision-rolled threaded steel bar is rotatably connected to the slide box; the other end passes through the threaded steel bar sleeve and the horizontal traction jack in sequence, and the precision-rolled threaded steel bar is threadedly connected to the horizontal traction jack. The horizontal traction jack rotates to drive the precision-rolled threaded steel bar to move, thereby achieving the purpose of tractioning the slide box. This traction method provides direct force transmission and precise control.

[0013] Furthermore, the vertical lifting jacks are provided in multiple sets and are evenly and fixedly connected to the inner bottom of the sliding box. The hydraulic rods of all the vertical lifting jacks extend vertically upward, and their top ends are used together to support the silo, ensuring that the lifting process is evenly stressed, stable and reliable.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Achieved stable displacement over ultra-long distances: Through tongue-and-groove sliding rail splicing technology, a seamless and continuous sliding track was formed, enabling the silo to smoothly transition through track joints, laying the structural foundation for achieving long-distance displacement of hundreds of meters.

[0015] 2. Excellent economic efficiency: The slide rail adopts a composite structure of "high-strength base layer + low-friction surface layer", which significantly reduces material costs while ensuring load-bearing capacity and low friction performance, resulting in good economic benefits.

[0016] 3. Stable and controllable displacement process: The guiding system composed of limiting angle steel and anchor blocks effectively prevents the box assembly from deviating during displacement. The lateral displacement assembly uses precision-rolled threaded steel for traction, with a clear force transmission path and precise stroke control. Multiple sets of vertical lifting jacks are evenly distributed to ensure stability and safety during the lifting and lowering of the silo. Modular structure and convenient construction: Each component has a clear structure and can be prefabricated and assembled on-site, improving construction efficiency and reducing on-site operation difficulty.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-8 This utility model provides an embodiment of a large silo long-distance displacement device, comprising a bottom fixing component 1, a track component 2, a box component 3, a lateral displacement component 4, a vertical lifting jack 5, and a silo 6. The bottom fixing component 1 serves as a foundation support and is laid on the ground. The track component 2 is laid above the bottom fixing component 1 along the displacement direction. The box component 3 is slidably supported above the track component 2 by its bottom. The lateral displacement component 4 is disposed between the box component 3 and the bottom fixing component 1 to provide power for the box component 3 to move along the track component 2. The vertical lifting jack 5 is fixedly installed inside the box component 3, and its hydraulic rod extends upward, with the top end used to support and lift the silo 6.

[0024] Specifically, the bottom fixing component 1 includes a base beam 101 and concrete reaction piers 102. Multiple sets of base beams 101 are arranged parallel to the extension direction of the track component 2. The concrete reaction piers 102 are fixedly installed on the base beams 101 and located at both ends of the extension direction of the track component 2. They are used to provide reaction force for the lateral displacement component 4. The base beams 101 effectively disperse the concentrated load on the upper part. The concrete reaction piers 102 set at both ends serve as solid anchor points, specifically used to balance and withstand the huge reaction force generated during horizontal traction, ensuring that the traction force is effectively applied to the box assembly.

[0025] Specifically, the track assembly 2 includes a slide rail 201, a limiting angle steel 202, and an anchor block 203. The slide rail 201 is fixedly laid on the upper surface of the base beam 101. The anchor block 203 is fixedly connected to the corner of the slide rail 201. The limiting angle steel 202 is set along the length of the slide rail 201 and fixed between adjacent anchor blocks 203 to guide and limit the box assembly 3. The slide rail 201 is the main load-bearing and sliding surface. The anchor block 203 serves as a connecting node to firmly install the limiting angle steel 202 on the slide rail 201. The limiting angle steel 202 maintains a small gap with both sides of the box assembly 3, forming a guide channel to effectively prevent the box from shifting laterally or deviating during movement, ensuring the accuracy of the displacement path.

[0026] Specifically, the front and rear ends of the slide rail 201 are provided with tongue and groove joints. Multiple sets of slide rails 201 are joined together along the length direction through the tongue and groove joints to form a continuous sliding track. This allows the box assembly 3 to slide smoothly through the joint. Through the tongue and groove joint technology, multiple slide rail segments can be seamlessly and smoothly connected into an ultra-long track, eliminating the steps or gaps that may be generated by traditional docking methods. This ensures that the box assembly and the silo it carries can pass through the track joint smoothly and without impact, which is the key to achieving long-distance continuous sliding.

[0027] Specifically, the slide rail 201 is composed of a base material and a surface material. The surface material is fixed on the upper surface of the base material, and the surface friction coefficient of the surface material is lower than that of the base material. The core function of the composite material design of the slide rail is to balance performance and cost. High-strength, low-cost base materials (such as steel) are used to ensure the structural strength and load-bearing capacity of the rail. At the same time, a surface material with a low friction coefficient (such as mirror stainless steel) is used to provide a smooth sliding interface to minimize sliding resistance, thereby achieving efficient and energy-saving traction.

[0028] Specifically, the housing assembly 3 includes a sliding box 301, an MGB plate 302, and a jack nozzle mounting hole 303. The MGB plate 302 is fixedly mounted on the lower surface of the sliding box 301 and forms a sliding pair with the upper surface of the track assembly 2. The jack nozzle mounting hole 303 is located on the side wall of the sliding box 301 and is used for installing and operating the jack nozzle. The sliding box 301 serves as the core load-bearing structure, integrating all lifting and sliding components. The MGB plate 302 cooperates with the track surface to form a low-friction pair, converting sliding friction into efficient solid lubrication and significantly reducing traction requirements. The jack nozzle mounting hole 303 provides an access point for hydraulic lines, facilitating subsequent installation and maintenance.

[0029] Specifically, the lateral displacement assembly 4 includes a horizontal traction jack 401, a precision-rolled threaded steel bar 402, and a threaded steel bar sleeve 403. The cylinder end of the horizontal traction jack 401 is fixedly connected to the concrete reaction pier 102. The threaded steel bar sleeve 403 is pre-embedded inside the concrete reaction pier 102. One end of the precision-rolled threaded steel bar 402 passes through the sliding box 301 and is threadedly connected to the threaded steel bar mounting bolt 404. The precision-rolled threaded steel bar 402 and the sliding box 301 are connected by a thread. The rotating connection connects the other end to the threaded steel sleeve 403 and the horizontal traction jack 401 in sequence. The fine-rolled threaded steel 402 is threadedly connected to the horizontal traction jack 401. The horizontal traction jack 401 rotates to drive the fine-rolled threaded steel 402 to move, thereby achieving the purpose of traction of the slide box 301. The threaded steel sleeve 403 protects the fine-rolled threaded steel from concrete abrasion. The through-hole jack drives the fine-rolled threaded steel by rotation, realizing large-tonnage traction with precise control and high efficiency.

[0030] Specifically, multiple sets of vertical lifting jacks 5 are evenly and fixedly connected to the inner bottom of the sliding box 301, and the hydraulic rods of the vertical lifting jacks 5 extend vertically upward, with their tops used to support the silo 6. By evenly arranging multiple sets of jacks at the bottom of the bearing platform (sliding box), the huge silo load is evenly distributed, and the overall stability and synchronization of the silo are maintained during the lifting and lowering process, effectively avoiding structural damage or overturning risks caused by uneven force.

[0031] Its working principle follows these steps in sequence: Step 1: Vertical lifting and load transfer First, connect the hydraulic pump station through the jack nozzle mounting hole 303 on the side wall of the housing assembly 3, and start all vertical lifting jacks 5.

[0032] Multiple sets of evenly arranged vertical lifting jacks 5, under the command of the synchronous control system, extend their hydraulic rods vertically upward synchronously and at a uniform speed to jointly push the silo 6 above.

[0033] As the jacks are lifted, the load of silo 6 is gradually transferred from its original foundation to a new rigid support system consisting of slide box 301, track assembly 2 and bottom fixing assembly 1, until the bottom of silo 6 is completely detached from the original foundation and the predetermined lifting height is reached.

[0034] Step 2: Lateral traction and long-distance sliding. After the silo 6 is fully lifted, the lateral displacement assembly 4 is activated. The cylinder of the horizontal traction jack 401 is fixed to the concrete reaction pier 102 as the origin of force application. The horizontal traction jack 401 rotates and drives the threaded steel bar 402 inserted therein through its internal movable connection. The other end of the threaded steel bar 402 is fixedly connected to the sliding box 301, thereby converting the thrust of the jack into a direct pulling force on the box assembly 3.

[0035] This pulling force drives the entire box assembly 3 and the silo 6 it carries to begin sliding along the track assembly 2. At this time, a high-performance sliding pair is formed between the MGB plate 302 fixed to the bottom of the sliding box 301 and the low-friction surface layer (such as a mirror stainless steel plate) fixed to the upper surface of the slide rail 201, which transforms sliding friction into low-resistance solid lubrication, making the movement of huge loads possible. The limiting angle steels 202 on both sides of the track continuously guide the sliding box 301 to prevent it from deviating during long-distance movement.

[0036] When it is necessary to cross the track joint, the tongue and groove structure at the end of the slide rail 201 ensures that the traveling mechanism of the slide box 301 can achieve a smooth transition without impact or vibration, ensuring the continuity of ultra-long distance displacement until the silo 6 is pulled to the target position.

[0037] Step 3: Precise positioning and load return Once the housing assembly 3, carrying the silo 6, has slid to a position directly above the target foundation, the lateral displacement assembly 4 ceases operation. The vertical lifting jack 5 is then operated again, controlling its hydraulic rods to retract synchronously and at a uniform speed, allowing the silo 6 to smoothly land on the new permanent foundation. After the load on the silo 6 has been completely transferred to the new foundation, this displacement device is dismantled, completing the entire displacement project.

[0038] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
