Description

Technical Field

[0001] The utility model belongs to the technical field of drag chain devices, and particularly relates to an impact-resistant reinforced drag chain device. Background Art

[0002] A drag chain device, also known as a cable drag chain, cable tray or cable trolley, is a device used to protect and guide cables, hoses, air pipes, etc. for reciprocating movement on mobile equipment. It can ensure that these cables and pipes will not be entangled, pulled or damaged during the movement of mechanical equipment; the drag chain device usually consists of a series of interconnected links, which can be plastic or metal, depending on the application requirements. The links are connected by hinges, so that the drag chain can bend and stretch to adapt to different movement paths. There are usually partition plates inside the drag chain to separate different types of cables and pipes to prevent them from rubbing or interfering with each other.

[0003] At present, when the drag chain device is in normal use, it is extremely vulnerable to strong mechanical shocks or vibrations due to external factors, which may cause the loosening or damage of its fixing points, thus causing displacement. The displacement may cause the cables and pipes inside the drag chain to be subjected to additional pulling, twisting or friction, thereby increasing the risk of damage. If the cables or pipes are damaged, it may lead to interrupted electrical connections, incorrect signal transmission or blocked fluid conveyance, affecting the normal function of the equipment.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0028] Embodiment 1

[0029] Referring to Figure 1-7 , this is the first embodiment of the present utility model. This embodiment provides an impact-resistant and reinforced drag chain device, including a drag chain mechanism 1, an impact resistance mechanism 2, and a positioning mechanism 6;

[0030] The impact-resistant mechanism 2 includes a rubber protection backing plate 201, damping springs 202, buffer gaskets 203, anti-collision guard plates 204, flexible joints 205 and fastening bolts 206. The buffer gaskets 203 are respectively arranged on the upper and lower sides of the damping springs 202. The damping springs 202 are distributed on the surface of the top of the rubber protection backing plate 201. The downward bends on both sides of the anti-collision guard plate 204 are fixedly connected to both sides of the top of the rubber protection backing plate 201. The flexible joints 205 are respectively located in the inner cavities on both sides of the rubber protection backing plate 201. The number of the fastening bolts 206 is four, and they are distributed around the top of the anti-collision guard plate 204 and are threadedly connected to a fixing mechanism 3.

[0031] Specifically, the fixing mechanisms 3 are respectively arranged on the front and rear sides of the surface of the drag chain mechanism 1. The fixing mechanism 3 includes a first mounting plate 301, a second mounting plate 302, a positioning rod 303, a threaded rod 304, a rocker 305, a first adjustment channel 306, a first limiting plate 307, a second limiting plate 308 and a second adjustment channel 309. The first mounting plate 301 is located on the left side of the drag chain mechanism 1. First adjustment channels 306 are opened at both the top and bottom on the left side of the first mounting plate 301. The threaded rod 304 is inserted through the inner cavity of the first adjustment channel 306 in a penetrating manner. A first limiting plate 307 is threadedly mounted on one side of the surface of the threaded rod 304. One end of the threaded rod 304 is provided with a rocker 305.

[0032] Further, the first mounting plate 301 and the second mounting plate 302 are respectively placed on the left and right sides of the drag chain mechanism 1. The threaded rod 304 is inserted into the inner cavity of the first adjustment channel 306 for adjusting the up and down position. At the same time, the positioning rod 303 can be inserted into the inner cavity of the second adjustment channel 309 for adjustment. After the adjustment, by holding the rocker 305 to drive the threaded rod 304 to rotate, the rotation will drive one end of the threaded rod 304 to be threadedly connected to one end of the positioning rod 303. After rotating to a suitable angle, the fixing mechanism 3 is fixedly installed on the surface of the drag chain mechanism 1.

[0033] Specifically, the second mounting plate 302 is located on the right side of the drag chain mechanism 1. Second adjustment channels 309 are opened at both the top and bottom on the right side of the second mounting plate 302. The positioning rod 303 is inserted through the inner cavity of the second adjustment channel 309 in a penetrating manner. One end of the positioning rod 303 is threadedly connected to the other end of the threaded rod 304. A second limiting plate 308 is sleeved on the other end of the positioning rod 303.

[0034] Further, when the positioning rod 303 adjusts the up and down position in the inner cavity of the second adjustment channel 309, the second limiting plate 308 can play a certain limiting role. The first limiting plate 307 will automatically move and adjust to achieve positioning following the rotation position of the threaded rod 304. The second limiting plate 308 limits the up and down position adjustment of the positioning rod 303. When the positioning rod 303 changes the left and right position, the position of the second limiting plate 308 needs to be manually moved.

[0035] Specifically, the positioning mechanism 6 is arranged at the bottom of the inner cavity of the drag chain mechanism 1. The positioning mechanism 6 includes an adjustment track 601, a rectangular groove 602, and a cable positioning component 603. The adjustment track 601 is opened at the top of the positioning mechanism 6, the rectangular groove 602 is opened on the left side of the adjustment track 601, and the cable positioning component 603 is clamped and installed in the inner cavity of the positioning mechanism 6.

[0036] Furthermore, the cable positioning component 603 can be placed by being clamped through the rectangular groove 602. After being placed, the cable positioning component 603 will be movably clamped in the inner cavity of the adjustment track 601 to achieve position adjustment.

[0037] Specifically, the cable positioning component 603 includes a movable clamping sleeve 603a, a fixed clamping sleeve 603b, a movable slider 603c, a buffer block 603d, a magnetic attraction groove 603e, and a magnet block 603f. The movable clamping sleeve 603a is hinged at the top of the fixed clamping sleeve 603b. The magnet block 603f is fixedly installed on the left side of the bottom of the movable clamping sleeve 603a. The magnetic attraction groove 603e is opened on the left side of the top of the fixed clamping sleeve 603b. The fixed clamping sleeve 603b is fixedly installed on the top of the movable slider 603c.

[0038] Furthermore, after the movable clamping sleeve 603a is opened, it is convenient to place the cable. And after being placed, the cable can be positioned by the acting force of mutual attraction between the magnet block 603 and the magnetic attraction groove 603e, avoiding collision or abrasion between the cables after they are located in the inner cavity of the drag chain mechanism 1.

[0039] Specifically, the movable slider 603c is movably clamped in the inner cavity of the positioning mechanism 6, and the buffer blocks 603d are respectively arranged on both sides of the movable slider 603c.

[0040] Furthermore, when the movable slider 603c freely slides in the inner cavity of the positioning mechanism 6, the provided buffer blocks 603d can effectively prevent collision between the movable sliders 603c.

[0041] Specifically, clamping holes 4 are opened on both sides at the rear of the drag chain mechanism 1, and clamping blocks 5 are fixedly installed on both sides at the front of the drag chain mechanism 1. The clamping blocks 5 are clamped and installed in the inner cavities of the clamping holes 4.

[0042] Furthermore, the clamping blocks 5 and the clamping holes 4 can realize the installation of multiple groups of drag chain mechanisms 1. Conversely, it is convenient to disassemble the drag chain mechanism 1.

[0043] Working principle: The first mounting plate 301 and the second mounting plate 302 are respectively placed on the left and right sides of the drag chain mechanism 1. The threaded rod 304 is inserted into the inner cavity of the first adjustment channel 306 for vertical position adjustment. At the same time, the positioning rod 303 can be inserted into the inner cavity of the second adjustment channel 309 for adjustment. After adjustment, the threaded rod 304 is driven to rotate by holding the rocker 305. The rotation will drive one end of the threaded rod 304 to be threadedly connected with one end of the positioning rod 303. After rotating to a suitable angle, the fixing mechanism 3 is fixedly installed on the surface of the drag chain mechanism 1. When the positioning rod 303 adjusts its vertical position in the inner cavity of the second adjustment channel 309, the second limiting plate 308 can play a certain limiting role. The first limiting plate 307 will automatically move and adjust with the rotation position of the threaded rod 304 to achieve positioning. After the movable ferrule 603a is opened, it is convenient to place the cable. After placement, the cable can be positioned by the adsorption force between the magnet block 603 and the magnetic adsorption groove 603e. The rubber protection cushion plate 201 can absorb and disperse the impact force, reducing the direct impact on the drag chain mechanism 1 itself. The buffer gasket 203 can be used at the connection points or joints of the drag chain mechanism 1 to provide additional buffering effect, reducing wear and damage caused by mechanical shock or vibration. The buffer gasket 203 is usually made of a flexible material and can absorb the impact energy to protect the structural integrity of the drag chain mechanism 1. The anti-collision guard plate 204 is installed outside the drag chain mechanism 1 to provide a physical barrier to prevent external objects from directly hitting the drag chain mechanism 1. The anti-collision guard plate 204 is made of polyurethane material, having a certain strength and impact resistance, and can protect the drag chain mechanism 1 from damage caused by accidental impact. At the same time, it can be bent when the drag chain mechanism 1 makes an angle adjustment together with the rubber protection cushion plate 201.

[0044] In summary, the overall beneficial effects of Embodiment 1: The fixing mechanism 3 is adjusted and positioned according to the drag chain mechanisms 1 of different sizes. Subsequently, the anti-impact mechanism 2 is directly installed at the fixing mechanism 3 through the fastening bolt 206. The rubber protection cushion plate 201 is installed on the movement paths on the upper and lower sides of the drag chain mechanism 1, which can absorb and disperse the impact force, reducing the direct impact on the drag chain mechanism 1 itself. The elastic characteristics of the rubber help buffer sudden impacts and protect the drag chain mechanism 1 from damage. The damping spring 202 is installed at the support structure or fixing points of the drag chain mechanism 1, which can effectively absorb and reduce the vibration transmitted to the drag chain mechanism 1. The elastic deformation of the damping spring 202 can buffer the impact force and reduce the dynamic load on the drag chain mechanism 1, thereby effectively improving the anti-impact ability of the drag chain mechanism 1 and reducing damage caused by mechanical shock or vibration.
