Description

Technical Field

[0001] This utility model belongs to the field of building engineering warehousing, specifically a mobile material shed. Background Technology

[0002] Materials are the source of enterprise production, and their effective management and safe storage are not only important means to improve production efficiency, but also a crucial foundation for cost reduction and efficiency improvement. The accelerating pace of increasing reserves and production in oil and gas fields poses greater challenges to material supply; high-quality development and the widespread use of new materials and processes place higher demands on material supply; in the high-sulfur region of northeastern Sichuan, a large amount of materials require sulfur and corrosion resistance, which places higher demands on the production, procurement, transportation, and storage of materials. This necessitates the storage of large quantities of bimetallic composite pipes, pipe fittings, instruments, flanges, etc., in warehouses, with some instruments and other materials even having higher requirements for temperature and humidity. To meet these requirements and adhere to high standards and regulations for material storage, mobile storage shed technology has been introduced. The use of mobile storage sheds avoids open-air storage of materials, significantly improving the quality of the material storage environment. Currently used mobile material sheds typically consist of a frame and a tarpaulin covering the frame. The frame includes multiple support frames and a scissor mechanism between adjacent support frames. Each support frame includes an arched roof joist and uprights fixed to both ends of the roof joist. Each upright has casters at its bottom, allowing the shed to move by rolling on the ground. During physical transport, forklifts or hoisting equipment are often used. During transport, the mobile material shed is usually folded up to expose the material, facilitating forklift or hoisting operations. After transport, the shed is unfolded to cover the material. However, in actual field use, we have found that traditional mobile material sheds using casters have the following drawbacks:

[0003] Firstly, the staff found it very difficult to push and pull the material shed;

[0004] Secondly, during the movement, the travel distance between the two sides of the material shed is significantly different, which not only affects the efficiency of the operation, but may also damage the stability of the material shed structure and shorten its service life. At the same time, the covering tarpaulin is also easily damaged.

[0005] Thirdly, it is supported by casters and relies on its own weight to resist wind, which has poor wind resistance. In strong winds, it is at risk of being blown away or overturned. Utility Model Content

[0006] The purpose of this invention is to provide a mobile material shed that improves the stability and mobility of the material shed.

[0007] The technical solution adopted by this utility model is: a mobile material shed, including a shed body and a moving mechanism disposed at its bottom. The shed body includes a tarpaulin and multiple support frames arranged longitudinally in a row. Each support frame includes a roof keel with an arc-shaped top and uprights fixed to both ends of the roof keel. The tarpaulin covers the roof keel. A scissor mechanism is installed between the uprights of adjacent support frames along the longitudinal direction. The moving mechanism includes a track system and a moving roller system. The track system includes two parallel tracks extending longitudinally, and the tracks are fixed to... The foundation is an I-beam, comprising an upper flange, a web, and a lower flange. The moving roller system includes multiple three-ring roller assemblies, each of which is fixedly installed at the bottom of the upright via a connecting bracket and matches the track. Each three-ring roller assembly includes a load-bearing roller and two limiting rollers. The load-bearing roller is located above the upper flange of the track and rolls in contact with the upper surface of the upper flange. The two limiting rollers are symmetrically arranged on both sides of the load-bearing roller and roll in contact with the lower surface of the upper flange of the I-beam track.

[0008] Furthermore, the lower flange of the track is fixed to the foundation by anchor bolts.

[0009] Furthermore, an installation groove is provided on the foundation that is recessed downward along the ground, and the track is installed in the installation groove, with the upper surface of the upper flange plate of the track parallel to the ground.

[0010] Furthermore, the connecting bracket includes a top plate and side plates fixed laterally to both sides of the top plate. The top plate and the side plates on both sides surround to form a groove-shaped structure with the opening facing downward. The lower surface of the top plate is provided with two lugs for installing load-bearing rollers. The load-bearing rollers are installed in the lugs. The limiting rollers are located in the groove and are rotatably installed on the side plates.

[0011] Furthermore, the connecting bracket also includes a sleeve, the bottom end of which is fixed to the top plate, the bottom of which is inserted into the sleeve, and a locking structure is provided between the upright and the sleeve.

[0012] Furthermore, the locking structure is formed by connecting bolts passing radially through the upright and sleeve and then tightening them with nuts.

[0013] Furthermore, both the upright and the sleeve have square cross-sections.

[0014] Furthermore, the load-bearing rollers and limiting rollers are made of nylon or polyurethane.

[0015] This utility model has the following beneficial effects: The mobile material shed disclosed in this utility model bears the vertical load through load-bearing rollers, and the limiting rollers on both sides are tightly and rollingly engaged with the side walls of the I-beam track, effectively limiting the lateral movement and swaying of the shed body, avoiding torsional deformation caused by uneven force, and greatly improving the overall structural stability. The rolling of the three-ring roller assembly on the track results in low frictional resistance, making the pushing and pulling of the material shed very convenient, reducing labor intensity and improving work efficiency. The tight connection between the three-ring roller assembly and the track improves wind resistance. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0023] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, B existing alone, or both A and B existing simultaneously.

[0024] Mobile material sheds, such as Figure 1 and Figure 2 As shown, the shed includes a main body and a moving mechanism located at its base. The main body includes a tarpaulin and multiple support frames 1 arranged longitudinally in a row. Each support frame 1 includes a canopy keel 1-1 with an arc-shaped top and uprights 1-2 fixed to both ends of the canopy keel 1-1. The tarpaulin covers the canopy keel 1-1. The edges of the tarpaulin are securely fixed to the canopy keel 1-1 using strips and fasteners to prevent the edges from being lifted or shaken by strong winds, reducing the impact of wind resistance on the shed structure, avoiding material damage caused by tarpaulin tearing, and improving wind resistance and durability. The tarpaulin is made of a material with excellent waterproof, fireproof, and mildew-proof properties. The tarpaulin is not shown in the figure.

[0025] Along the longitudinal direction, a scissor mechanism 2 is installed between the uprights 1-2 of two adjacent support frames 1. The scissor mechanism 2 connects the two adjacent support frames 1, so that the two adjacent support frames 1 can be closed or opened. The moving mechanism includes a track system and a moving roller system. The track system includes two parallel tracks 3 extending longitudinally, fixed to the foundation. Each track 3 is an I-beam, comprising an upper flange, a web, and a lower flange. The moving roller system includes multiple three-ring roller assemblies 4. Each three-ring roller assembly 4 is fixedly installed at the bottom end of the upright 1-2 via a connecting bracket 5 and matches the track 3. Each three-ring roller assembly 4 includes a load-bearing roller 4-1 and two limiting rollers 4-2. The load-bearing roller 4-1 is located above the upper flange of the track 3 and rolls in contact with the upper surface of the upper flange. The two limiting rollers 4-2 are symmetrically arranged on both sides of the load-bearing roller 4-1 and roll in contact with the lower surface of the upper flange of the I-beam track 3, respectively.

[0026] The I-beam track 3, due to its cross-sectional characteristics, possesses high bending strength and torsional stiffness, enabling it to bear large loads and exhibiting good stability. The three-ring roller assembly 4, in conjunction with the I-beam track 3, forms a low-friction, high-stability sliding pair. The load-bearing roller 4-1 transfers the vertical load to the track 3, while the two limiting rollers 4-2 clamp the I-beam track 3 from both sides, forming a reliable three-point contact anti-overturning constraint. This low-friction, high-stability sliding pair, along with the reliable anti-overturning constraint, significantly reduces the force required to push the material shed, making operation extremely labor-saving and ensuring the material shed always moves in a straight line along the track without deviating.

[0027] After deployment, the scissor lift mechanism provides stable triangular support in the longitudinal direction, enhancing overall rigidity. Simultaneously, the moving roller system firmly locks the shed onto the tracks, limiting lateral displacement. The combination of these two elements improves the structural stability and wind resistance of the material shed, effectively resisting lateral wind loads and preventing swaying or overturning during movement or when stationary.

[0028] To further enhance wind resistance, ground anchors or ground bolts are installed on the outer side of the main body of the shed. These anchors or bolts provide additional windproof reinforcement. Once the shed is positioned, it can be secured to the ground with ropes or chains, forming a second layer of wind protection. This significantly enhances the shed's resistance to overturning when stationary, making it particularly suitable for strong wind environments in the field.

[0029] Preferably, the lower flange of the track 3 is fixed to the foundation by anchor bolts 8. The anchor bolt fixing method provides a stable foundation for the entire mobile material shed. It ensures that the track 3 will not shift due to the movement of the material shed body or external wind loads, guaranteeing the long-term alignment and reliable operation of the entire system, and further enhancing the overall stability of the material shed under adverse weather conditions.

[0030] The track 3 can be directly installed on the ground. In this embodiment, a mounting groove 6 is provided on the foundation, recessed downwards along the ground. The track 3 is installed in the mounting groove 6, and the upper surface of the upper flange plate of the track 3 is parallel to the ground. This structure completely eliminates the obstacle formed by the track 3 being higher than the ground. This allows forklifts, handcarts, and other equipment and personnel to move smoothly and unobstructed around and inside the material shed, greatly improving the accessibility and efficiency of the work area and avoiding safety risks caused by tripping or bumping.

[0031] Furthermore, the connecting bracket 5 is a single piece, including a top plate 5-1 and side plates 5-2 fixed laterally on both sides of the top plate 5-1. The top plate 5-1 and the side plates 5-2 surround to form a downward-facing groove structure. The lower surface of the top plate 5-1 is provided with two lugs 5-4 for mounting load-bearing rollers 4-1. The load-bearing rollers 4-1 are mounted on the lugs 5-4. The limiting rollers 4-2 are located in the groove and are rotatably mounted on the side plates 5-2.

[0032] The channel-shaped connecting bracket 5 has good bending resistance, which can significantly enhance the vertical and lateral stiffness of the connecting bracket 5, thereby more stably bearing and transmitting the load from the material shed body and preventing the connecting bracket 5 from deforming under heavy load. It integrates the load-bearing roller 4-1 and the limiting roller 4-2 into a compact channel-shaped space. The load-bearing roller 4-1 is rotatably supported on both sides of the lug 5-4 by bearings, etc., and the limiting roller 4-2 is built into both sides of the channel, making the entire roller system compact and rationally laid out. The fit with the I-beam rail 3 is more precise and reliable, and it can effectively prevent the roller system from detaching from the rail 3.

[0033] The bottom end of the upright 1-2 can be directly welded to the top plate 5-1. Preferably, in this embodiment, the connecting bracket 5 also includes a sleeve 5-3. The bottom end of the sleeve 5-3 is fixed to the top plate 5-1, the bottom of the upright 1-2 is inserted into the sleeve 5-3, and a locking structure is provided between the upright 1-2 and the sleeve 5-3.

[0034] The sleeve 5-3 is fixed to the upper surface of the top plate 5-1, providing an insert-type connection for the upright 1-2. This simplifies the assembly process of the moving roller system and the material shed body, reducing installation difficulty. The insert-type connection between the upright 1-2 of the material shed body and the sleeve 5-3 also facilitates disassembly, replacement, and transportation.

[0035] The locking structure ensures that the upright 1-2 is fixed to the sleeve 5-3, preventing relative movement and improving the stability of the material shed in both moving and fixed states. It can be a pin or similar structural form. In this embodiment, the locking structure is formed by connecting bolts 7 passing radially through the upright 1-2 and sleeve 5-3 and then tightening them with nuts.

[0036] Both the upright 1-2 and the sleeve 5-3 have square cross-sections.

[0037] In this embodiment, the load-bearing roller 4-1 and the limiting roller 4-2 are made of nylon or polyurethane. Using non-metallic materials such as nylon or polyurethane for the rollers firstly avoids the noise and sparks generated by friction between the steel wheel and the rail, making it safer; secondly, these materials have a certain degree of self-lubrication and elasticity, which can reduce the coefficient of friction and wear, while protecting the surface of the I-beam rail 3 and extending the service life of the entire sliding system.

[0038] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
