Description

Technical Field

[0001] This utility model relates to the technical field of roof chain trench covering structures, and in particular to a compact automatic roof chain trench covering structure. Background Technology

[0002] A mobile workbench is an automated device that runs on ground rails and is widely used in industrial production.

[0003] To ensure a stable power and air supply for the mobile workbench during operation, cable chains are typically used to carry cables and hoses. Cable chains not only effectively protect cables and hoses from environmental damage but also ensure their neat arrangement and prevent tangling during movement. Therefore, to prevent the cable chain from being exposed on the ground, existing technologies usually employ an automatic top-plate chain trench covering mechanism. This mechanism mainly consists of an upper support, a lower support, grooved rollers, flat rollers, and a top-plate chain. The grooved rollers are mounted between the upper supports via shafts, while the flat rollers are mounted at both ends of the lower support. The top-plate chain covers the trench and, guided by the grooved and flat rollers, forms an arched structure, ensuring the mobile workbench can pass smoothly during operation.

[0004] The inventors discovered that the aforementioned prior art suffers from at least the following drawbacks: Because the groove rollers and flat rollers form a layered structure, the top plate chain needs to pass through multiple rollers to form an arch, which increases the overall size of the mechanism. Furthermore, cables and hoses need to pass under the mechanism, further increasing its space requirements. Therefore, in installation environments with limited space, this top plate chain trench covering mechanism often fails to meet practical needs, limiting its application range. Utility Model Content

[0005] This application provides a compact automatic covering structure for roof chain trenches, which solves the technical problem of large space occupation in existing roof chain trench covering mechanisms.

[0006] To solve the aforementioned technical problems, this utility model adopts the following technical solution: a compact automatic covering structure for a top plate chain trench, comprising a top plate chain II covering the trench and two fixed supports mounted on a movable workbench. A circular ring and two pressure blocks are installed between the two fixed supports, with the two pressure blocks located on opposite sides of the circular ring. The top plate chain II passes through the bottom of the pressure blocks and the top of the circular ring, forming an arch. Both fixed supports have through holes aligned with the inner cavity of the circular ring. This structure, by supporting the circular ring and pressure blocks with the two fixed supports, allows the top plate chain II to form an arch after passing through the bottom of the pressure blocks and the top of the circular ring, effectively reducing the overall space occupied. Simultaneously, the alignment of the through holes on the fixed supports with the inner cavity of the circular ring facilitates the passage of cables and flexible conduits, adapting to the installation requirements of confined spaces and improving space utilization and wiring flexibility.

[0007] As a further improvement to the above solution, the fixed bracket is plate-shaped, and the ring and pressure block are located between the two fixed brackets, with the two pressure blocks located near the two ends of the fixed bracket.

[0008] As a further improvement to the above solution, connecting rods are inserted through both the ring and the pressure block, and the two ends of the connecting rods are fixed to two fixed brackets respectively; a transverse column is also inserted through the pressure block, and the two ends of the transverse column are inserted through two fixed brackets and connected to an adjustment component, which is fixed to the movable worktable.

[0009] As a further improvement to the above solution, the adjustment assembly includes an adjustment screw, a lower nut, spring I, and an upper nut. The adjustment screw extends vertically through the end of the transverse column and is fixed to the movable worktable. The lower nut engages with the adjustment screw and is located below the end of the transverse column. Spring I is located above the end of the transverse column, and the upper nut is pressed against the top of spring I. The height of the transverse column can be adjusted by the engagement of the lower nut and the adjustment screw, thereby changing the height of the top plate chain arch. Spring I provides elastic support, which can adapt to different tension requirements of the top plate chain and maintain the stability and reliability of the structure.

[0010] As a further improvement to the above solution, two nuts are installed on the upper part of each adjusting component; this prevents loosening and improves the stability of the structure.

[0011] As a further improvement to the above scheme, the holes through which the connecting rods and transverse columns pass in the pressure block are strip-shaped holes, and the length direction of the strip-shaped holes is consistent with the horizontal extension direction of the top plate chain; thus, even when the fixed bracket is fixed, the pressure blocks on both sides of the ring can be finely adjusted within a certain range, thereby ensuring the fit of the top plate chain II and improving the flexibility of the structure.

[0012] As a further improvement to the above scheme, the middle part of the transverse column also has a threaded hole that passes through it radially. A screw is installed in the threaded hole, and one end of the screw abuts against a spring II. The length direction of the spring II is consistent with the horizontal extension direction of the top plate chain II. The pressure block always maintains an appropriate clamping force on the top plate chain II to ensure the stability of this structure and the top plate chain II during relative movement.

[0013] As a further improvement to the above scheme, the side of the pressure block that contacts the top plate chain II is an arc surface; this can improve the fit between the pressure block and the top plate chain.

[0014] As a further improvement to the above solution, a cable chain mounting bracket is connected to the bottom of the fixed bracket, and a cable chain mounting bracket is connected to the cable chain.

[0015] As a further improvement to the above solution, the cable chain mounting bracket and the fixed bracket are integrated into one structure.

[0016] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages:

[0017] 1. This utility model supports the ring and pressure block with two fixed brackets, so that the top plate chain II forms an arch after passing through the bottom of the pressure block and the top of the ring, which effectively reduces the overall space occupied. At the same time, the through holes on the fixed brackets are aligned with the inner cavity of the ring, which facilitates the passage of cables and hoses, adapts to the installation requirements of narrow environments, and improves space utilization and wiring flexibility.

[0018] 2. Since there are adjustment components at both ends of the transverse column, the height of the top plate chain arch can be changed by adjusting the components, which is conducive to the smooth operation of the top plate chain II. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0028] To better understand the improvements made by this utility model compared to the prior art, the prior art mentioned in the background section will be explained in conjunction with the accompanying drawings before a detailed description of the specific embodiments of this utility model.

[0029] Figure 1 and Figure 2 The specific structure of the automatic covering mechanism for the top plate chain trench disclosed in the prior art Chinese utility model patent application publication CN204400016U and the specific application of the mechanism are shown respectively.

[0030] like Figure 1 , Figure 2 As shown, the lower support 1 is mounted on the movable worktable by fixing bolts 2 and clamping springs 3, and the upper support 4 is mounted above the lower support 1 by fastening bolts 5. The grooved roller 6 is mounted between the two upper supports 4 by a shaft, and the flat roller 7 is mounted at both ends of the two lower supports 1 respectively. This mechanism, through the arrangement of the grooved roller 6 and the flat roller 7, can realize its movement relative to the top plate chain I 8.

[0031] exist Figure 1 and Figure 2In the disclosed automatic top-plate chain covering mechanism, the grooved rollers 6 and flat rollers 7 form a layered structure, with the top-plate chain I8 covering the trench and fixed at both ends. To ensure the stability of the mechanism during movement, the lower surface of the top-plate chain I8 needs to press against the grooved rollers 6, and the flat rollers 7 need to press against the upper surface of the top-plate chain I8. That is, the top-plate chain I8 needs to pass through four flat rollers 7 and three grooved rollers 6 to form an arched structure, while cables and air pipes also need to pass through the underside of the mechanism. Therefore, this structure occupies a large amount of space and is not suitable for installation in small spaces.

[0032] The present invention addresses the problem that existing top-plate chain trench covering mechanisms occupy a large overall space and are unsuitable for installation in smaller spaces. The specific embodiments of the present invention are described in detail below.

[0033] This utility model discloses a compact automatic covering structure for roof chain trenches, such as Figures 3 to 6 As shown, it includes a top plate chain II 9 covering the trench and two fixed supports 10 mounted on a movable workbench. The two fixed supports 10 are plate-shaped structures, and a ring 11 and two pressure blocks 12 are installed between the two fixed supports 10. The two pressure blocks 12 are located on both sides of the ring 11 and close to the two ends of the fixed supports 10.

[0034] The top plate chain II9 passes through the bottom of the pressure block 12 and the top of the ring 11 to form an arched structure. Both fixed brackets 10 are provided with through holes, the positions of which are aligned with the inner cavity of the ring 11. Thus, the cables and hoses in the cable carrier in the trench can pass through the through holes of the fixed brackets 10 and the ring 11 to enter the mobile workbench, thereby effectively reducing the overall space occupied and adapting to the installation requirements of confined spaces.

[0035] Specifically, in this embodiment, connecting rods 13 are inserted through both the ring 11 and the pressure block 12. The two ends of the connecting rods 13 are fixed to two fixed brackets 10 respectively to ensure the overall stability of the structure. A transverse column 14 is also installed through the pressure block 12. The two ends of the transverse column 14 are inserted through the two fixed brackets 10 respectively and connected to an adjustment component. The pressure of the pressure block 12 on the top plate chain II 9 can be adjusted by the adjustment component.

[0036] The adjustment assembly includes an adjustment screw 15, a lower nut 16, a spring I 17, and an upper nut 18. The adjustment screw 15 extends vertically through the end of the transverse column 14 and is fixedly connected to the movable worktable, thereby enabling the installation of the fixed bracket 10 on the worktable. The lower nut 16 cooperates with the adjustment screw 15 and is located below the end of the transverse column 14. When the lower nut 16 is rotated, the transverse column 14 can move upward or downward, thereby changing the arch height of the top plate chain II 9. The upper nut 18 is located at the top of the adjustment screw, and the spring I 17 is located between the transverse column 14 and the upper nut 18, providing elastic support and allowing the structure to adapt to different tension requirements of the top plate chain II 9. Preferably, two upper nuts 18 are installed in each adjustment assembly, thereby effectively preventing loosening and improving the stability of the structure through the double nut design.

[0037] To further improve the flexibility of adjustment, the holes through which the connecting rod 13 and the transverse column 14 pass in the pressure block 12 are strip-shaped holes, and the length direction of the strip-shaped holes is consistent with the horizontal extension direction of the top plate chain II 9. Therefore, even when the fixed bracket 10 is fixed, the pressure blocks on both sides of the ring 11 can be finely adjusted within a certain range, thereby ensuring the fit of the top plate chain II 9.

[0038] Furthermore, the transverse column 14 has a threaded hole in its center, through which it passes radially. A screw 19 is installed in the threaded hole, with one end of the screw 19 abutting against a spring II 20. The other end of the screw II 20 extends along the horizontal extension direction of the top plate chain II 9 to the outside of the pressure block 12. The length direction of the spring II 20 is consistent with the horizontal extension direction of the top plate chain II 9. Thus, under the elastic force of the spring II 20, the pressure block 12 can be prevented from loosening, ensuring that the pressure block 12 is always tightly pressed against the top plate chain II 9. Moreover, when the present invention vibrates or shifts during movement, the spring II 20 can absorb some of the vibration energy, so that the pressure block 12 always maintains an appropriate clamping force on the top plate chain II 9.

[0039] On the other hand, in this embodiment, the side of the pressure block 12 that is used to contact the top plate chain II 9 is an arc surface. The arc surface of the pressure block 12 can increase the contact area between the pressure block 12 and the top plate chain II 9, and improve the fit between the pressure block 12 and the top plate chain II 9.

[0040] In addition, such as Figure 3 , Figure 4 As shown, to facilitate the installation and fixing of the cable chain, a cable chain mounting bracket 21 is also connected to the bottom of the fixing bracket 10. The cable chain mounting bracket 21 and the fixing bracket 10 can be an integral structure or a detachable connection structure.

[0041] In application, the top plate chain II9 covers the trench and is fixed at both ends. After passing through the pressure block 12 and the ring 11, the top plate chain II9 forms an arched structure, avoiding the need for flat rollers and grooved rollers, thus occupying less space overall. Simultaneously, cables and pipelines in the cable trench can pass through the drag chain mounting bracket 21 and then be connected to the mobile worktable via the through hole of the fixed bracket 10 and the ring 11, allowing for more flexible cable and pipeline arrangement.
