Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics track, in particular to a mounting structure of logistics track. BACKGROUND

[0002] In modern buildings, especially in office buildings, hospitals, hotels and other places, in order to maintain the beauty and cleanliness of the internal space, suspended ceilings are usually installed to hide pipelines, air ducts and other equipment. At the same time, in order to improve logistics efficiency and reduce labor costs, automated guided vehicles, suspended logistics conveying systems and other automated logistics equipment are increasingly widely used. Logistics tracks need to be stably installed on building structures, and corridors are often the only way to install tracks as the key passageway connecting various functional areas. At present, the mainstream method for installing such tracks in corridors usually has the following technical defects: limited installation foundation and poor adaptability: traditional installation methods often rely on directly fixing a hanger to the building roof (floor), and then installing a track at the lower end of the hanger. However, in the corridor environment, the top space is often occupied by various pipelines and bridge structures, resulting in a mismatch between the track installation position and the available anchor points on the roof. In addition, the track path often needs to cross two different height or material suspended ceiling areas, and the traditional single hanger installation method is difficult to stably fix on such non-continuous and uneven top structures. Insufficient adjustment capability and low installation efficiency: the existing installation structure often lacks effective adjustment mechanism. During installation, each hanger needs to be accurately measured and cut to ensure the levelness of the installed track. This process is time-consuming and labor-intensive, and once an error occurs, it is difficult to rework, which seriously affects the installation efficiency and accuracy. Large damage to existing structures and questionable stability: when the track needs to be installed on the side of the suspended ceiling, the construction personnel may use self-tapping screws to directly penetrate the suspended ceiling joist or even the suspended ceiling plate itself for fixation, which not only damages the integrity of the suspended ceiling structure, but also cannot guarantee its bearing capacity and long-term stability, posing a safety hazard. SUMMARY

[0003] In view of the deficiencies in the prior art, the purpose of the present application is to provide a mounting structure of logistics track to solve the technical problems of difficult installation and difficult adjustment of installation precision of logistics track in the prior art.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows: A mounting structure of logistics track is installed between a corridor roof and two suspended ceilings, and an installation position for installing a track is formed between the two suspended ceilings. The mounting structure comprises: a suspension structure comprising two spaced apart threaded rods, one end of each threaded rod being connected to the roof and the other end extending towards the installation position; The fixing member comprises a cross arm and two C-shaped clamps, two ends of the cross arm are movably connected with two side walls of the ceiling through the threaded rods, upper ends of the C-shaped clamps are clamped on the cross arm, and lower ends of the C-shaped clamps are connected with the track. The C-shaped clamps have a first fixing direction and a second fixing direction, and the first fixing direction is perpendicular to the second fixing direction.

[0005] Further, upper ends of the C-shaped clamps are provided with first clamping plates and second clamping plates, the first clamping plates and the second clamping plates are arranged in a front-rear direction, and the first clamping plates and the second clamping plates are used for clamping opposite end surfaces of the cross arm.

[0006] Further, the first clamping plate is fixed at a front end of the C-shaped clamp, and the second clamping plate is movably arranged at a rear end of the C-shaped clamp through a lead screw.

[0007] Further, a bottom end of the C-shaped clamp is screw-connected with an abutting column, and the abutting column abuts against a bottom surface of the cross arm.

[0008] Further, opening directions of the two C-shaped clamps are opposite.

[0009] Further, opposite end surfaces of the cross arm are provided with fixing grooves, the first clamping plate and the second clamping plate are provided with fixing blocks, the fixing blocks can be inserted into the fixing grooves, and the first clamping plate and the second clamping plate are clamped on two ends of the cross arm.

[0012] Compared with the prior art, the present application has the following beneficial effects: 1. By setting the combination of the suspension structure and the fixing member, using the cross arm as a bridge spanning two ceilings, the upper end of the threaded rod is fixed to the solid building roof, and the lower end is transferred to the side walls of the two ceilings through the cross arm, so that the track is no longer dependent on the ceiling itself as the main bearing structure, and the load is effectively transmitted to the building main body; 2.

[0015] The present invention will be further described in detail below through specific embodiments: In embodiments of the present invention, such as Figures 1-4 As shown, an installation structure for a logistics track 7 is installed between a corridor ceiling slab 1 and two suspended ceilings 2. The space between the two suspended ceilings 2 is configured as an installation position for the track 7. The installation structure includes: The suspension structure includes two threaded rods 3 spaced apart, one end of each threaded rod 3 being connected to the top plate 1 and the other end extending toward the mounting position. The fastener includes a crossbeam 5 and two C-clamps 4. The two ends of the crossbeam 5 are movably connected to the side walls of the two ceilings 2 with the corresponding threaded rods 3. The upper end of the C-clamps 4 is clamped to the crossbeam 5, and the lower end is connected to the track 7. The C-shaped clip 4 has a first fixed direction and a second fixed direction, and the first fixed direction is perpendicular to the second fixed direction.

[0016] In this embodiment, when installing the track 7, first fix one end of the two threaded rods 3 to the ceiling 1, and extend the other end vertically to the installation position. Then thread the two fixing members to the end of the threaded rods 3 near the installation position, and adjust the length by rotating the threaded rods 3 to adapt to the height changes or unevenness of the ceiling 1. The threaded rods 3 provide fine adjustment capability in the vertical direction, allowing the track 7 to be accurately aligned with the installation position. The fixing member includes a cross arm 5 and a C-shaped clamp 4. The two ends of the cross arm 5 are threadedly connected to the ends of the two vertically arranged threaded rods 3, and are located on the side walls of the two suspended ceilings 2, allowing the cross arm 5 to move up and down in the horizontal direction to adapt to the changes in the distance between the side walls of the suspended ceilings 2 or installation errors. The upper end of the C-shaped clamp 4 is clamped to the cross arm 5, and the lower end is connected to the track 7, without the need for welding and direct fixing, facilitating adaptive adjustment of the track 7 during installation. At the same time, the C-shaped clamp 4 has a first fixing direction and a second fixing direction, which are perpendicular to each other. The logistics track 7 bears forces in multiple directions (such as vertical load and horizontal inertial force) during operation, so the C-shaped clamp 4 needs to be able to withstand these forces. The first fixing direction (e.g. horizontal direction) and the second fixing direction (e.g. vertical direction) are perpendicular to each other, allowing the C-shaped clamp 4 to constrain the movement of the track 7 in both directions, improving overall stability. The double-direction fixing design ensures the firmness of the track 7 in three-dimensional space, reducing the risk of vibration and deviation. In addition, since the installation is located between the two suspended ceilings 2, the structure is compact and does not occupy additional space. The double-direction design of the C-shaped clamp 4 allows the track 7 to be close to the side walls of the suspended ceilings 2, maximizing the use of narrow corridor space. The double fixing direction of the C-shaped clamp 4 provides multi-directional constraint, which is more reliable than single direction fixing, significantly reduces the risk of track 7 derailment or deformation, and improves the safety and service life of the track 7. The track 7 installation structure uses standardized parts (such as threaded rods 3 and C-shaped clamps 4), and the modular design makes installation as simple as assembling building blocks. Compared with the prior art, it reduces on-site welding or cutting, and the installation efficiency is improved by more than 50%, reducing labor costs. The structure is suitable for various corridors and suspended ceilings 2, without the need for customization for each project, reducing inventory and design costs, and reducing the overall cost of ownership compared with the prior art, improving the scalability of the project.

[0017] The upper end of the C-shaped clamp 4 is provided with a first clamping plate 41 and a second clamping plate 42, which are spaced apart in front and back directions and used to clamp opposite end faces of the cross arm 5.

[0018] In this embodiment, the upper end of the C-shaped clamp 4 is provided with a first clamping plate 41 and a second clamping plate 42, which are spaced apart in the front-rear direction and clamped to the opposite end faces of the cross arm 5. During operation of the track 7, the track 7 trolley needs to be transported back and forth for a long time, and the first clamping plate 41 and the second clamping plate 42 provide strong clamping force to the two sides of the cross arm 5, ensuring that the track 7 does not shake or loosen during long-term operation.

[0019] The first clamping plate 41 is fixed to the front end of the C-shaped clamp 4, and the second clamping plate 42 is movably arranged at the rear end of the C-shaped clamp 4 through a lead screw 45.

[0020] In this embodiment, during installation, the two C-shaped clamps 4 are clamped to the cross arm 5 with a spacing, and the installation position between them is adjusted so that the lower end of the track 7 is parallel to the two suspended ceilings 2, and then the second clamping plate 42 is driven by the lead screw 45 to move towards the first clamping plate 41, so as to lock the C-shaped clamp 4 on the cross arm 5.

[0021] The bottom end of the C-shaped clamp 4 is provided with an abutting column 6, which abuts against the bottom surface of the cross arm 5.

[0022] In this embodiment, the gravity of the track 7 itself, the track 7 trolley and the C-shaped clamp 4 are completely dependent on the clamping friction force of the lead screw 45 and the second clamping plate 42 at the upper end of the C-shaped clamp 4 to bear, which has certain risks. In long-term use or under heavy load, the clamping force may loosen. A abutting column 6 is arranged at the lower end of the C-shaped clamp 4, which abuts against the bottom surface of the cross arm 5 in the up-down direction, and converts the heavy vertical force from shear force (friction force of the clamping plate) to more suitable pressure (supporting force of the abutting column 6). The main function of the first clamping plate 41 and the second clamping plate 42 is changed from bearing to anti-swing and anti-twist, which greatly improves the safety; at the same time, by rotating the abutting column 6, the installation height of the C-shaped clamp 4 and the track 7 hung below it can be accurately fine-tuned, ensuring that multiple tracks 7 are on the same horizontal plane, to compensate for the slight unevenness of the building structure itself.

[0023] The opening directions of the two C-shaped clamps 4 are opposite.

[0024] In this embodiment, the opening directions of the two C-shaped clamps 4 are set to be opposite, which aims to optimize the stress and prolong the fatigue life of the cross arm 5 and the entire structure. If the opening directions of the two C-shaped clamps 4 are the same (for example, both forward), when the track 7 trolley runs between the two C-shaped clamps 4, the track 7 will be slightly bent like a beam, and this bending will produce a prying effect on the upper end of the C-shaped clamp 4. For each C-shaped clamp 4, the force exerted by the track 7 will form a couple (a pair of forces of equal magnitude and opposite direction) at the first clamp plate 41 and the second clamp plate 42. Since the first clamp plate 41 and the second clamp plate 42 of all C-shaped clamps 4 are fixed in the same direction, this couple will cause all cross arms 5 to twist in the same direction, generating a continuous and cyclic torsional stress on the cross arm 5, which will concentrate on the fixed area of the cross arm 5, especially the part connected with the threaded rod 3 and the part clamped by the C-shaped clamp 4, and is prone to metal fatigue. When the opening directions of the two C-shaped clamps 4 are opposite (for example, one forward and one backward), the mechanical model changes fundamentally. Similarly, when the trolley is located between the two C-shaped clamps 4, the bending of the track 7 will produce opposite prying forces on the two C-shaped clamps 4. The first C-shaped clamp 4 twists the cross arm 5 clockwise, and the second C-shaped clamp 4 twists the cross arm 5 counterclockwise. The two opposite moments will cancel out a large part of each other on the cross arm 5, so that the cross arm 5 no longer mainly bears the repeated torsional stress, but more bears the relatively uniform vertical bending stress. The distribution of bending stress on the cross section of the cross arm 5 is more uniform than the torsional stress, and its maximum value is usually lower. Through the torque cancellation of the opposite installation of the two C-shaped clamps 4, the stress cycle amplitude borne by the cross arm 5 is significantly reduced, prolonging the fatigue life. The stress changes from mainly torsional to mainly bending. For common section steels (such as square tubes and I-beams), their bending resistance is usually better than their torsional resistance. Letting the material work in the stress mode it is better at naturally makes it more durable. Avoiding the cross arm 5 being repeatedly stressed in a single direction, the local pressure at the clamping point of the C-shaped clamp 4 also becomes more symmetrical and stable, reducing the risk of fretting wear and fatigue crack initiation.

[0025] The opposite end surfaces of the cross arm 5 are each provided with a fixing groove 51, and the first clamp plate 41 and the second clamp plate 42 are provided with a fixing block 43, which can extend into the fixing groove 51 and clamp the first clamp plate 41 and the second clamp plate 42 to the two ends of the cross arm 5.

[0026] In this embodiment, on the two opposite end faces of the cross arm 5 (i.e. the side faces clamped by the first clamping plate 41 and the second clamping plate 42), a fixing groove 51 is arranged, and a fixing block 43 is arranged on the first clamping plate 41 and the second clamping plate 42, the fixing block 43 is matched in shape and size with the fixing groove 51 on the cross arm 5, when installed, the fixing block 43 on the first clamping plate 41 and the second clamping plate 42 extends into the fixing groove 51 of the cross arm 5, when the track 7 tries to rotate the C-shaped clamp 4 around the cross arm 5 under stress, the side face of the fixing block 43 will immediately contact with the side wall of the fixing groove 51, effectively transmitting the torque to the cross arm 5, thereby effectively inhibiting the torsion, partially converting the entire structure from the clamping connection mode to an inlaid connection mode, significantly improving the rigidity of the connection between the C-shaped clamp 4 and the cross arm 5, so that the vibration and deformation of the track 7 during operation is greatly reduced, and the operation is more stable.

[0027] The fixing groove 51 is provided with a locking groove 52 communicated therewith in the up-down direction, the fixing block 43 is movably provided with two locking blocks 44, the locking block 44 has a mounting state hidden in the fixing block 43 and a locking state protruding outside the fixing block 43, in the locking state, the locking block 44 is clamped with the locking groove 52.

[0028] In this embodiment, the locking groove 52 is arranged in communication with the fixing groove 51 at the upper and lower ends of the fixing groove 51, and two movable locking blocks 44 are arranged at the upper and lower ends of the fixing block 43, one end of the locking block 44 is movably connected to the fixing block 43 through a torsion spring, in the installation, the two locking blocks 44 are pressed tightly to make them fit with the fixing block 43, until the root of the locking block 44 completely extends into the fixing groove 51, the locking block 44 extends out from the upper and lower sides of the fixing block 43 through the torsion spring, in this state, the extended locking block 44 will be clamped into the corresponding locking groove 52 of the cross arm 5 in the up-down direction, finally, the screw rod 45 at the upper end of the C-shaped clamp 4 is tightened, and the entire clamping process is completed, even if the screw rod 45 at the upper end of the C-shaped clamp 4 is loosened, as long as the locking block 44 is in the locking state, the C-shaped clamp 4 cannot directly fall off the cross arm 5, the locking block 44 is clamped in the locking groove 52, forming a mechanical constraint in the vertical direction, providing a crucial safety backup for the entire installation structure, preventing the entire installation structure from failing in extreme cases.

[0029] The cross section of the locking block 44 is triangular.

[0030] In this embodiment, the slope of the triangle constitutes a simple slope mechanism. When the locking block 44 is subjected to an upward force, it will be decomposed into two components, one normal to the slope, a normal force, and one parallel to the slope, a friction force, directed towards the interior of the triangle. Under a reasonable slope angle, the friction force is sufficient to prevent the locking block 44 from moving upward. Once the locking block 44 comes into abutment with the locking groove 52, the locking block 44 will be pulled tighter, having a self-locking function, greatly enhancing the anti-vibration and anti-impact capabilities. The tip of the triangular locking block 44 provides a guide surface when entering the locking groove 52. The slope guides the locking block 44 to smoothly slide into the locking groove 52. The root of the triangular locking block 44 has the maximum width, and the bending moment is also the largest. When it comes into abutment with the locking groove 52, the root comes into abutment with the inner wall of the locking groove 52, enhancing the bending strength.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and they should be covered in the scope of the claims of the present application.
