[0026] Figures 1 to 3A double-channel steel rail sliding device in an embodiment of the utility model is shown, which can be used for rail transportation of heavy equipment such as CCTV equipment, and may include a rail assembly 100 and a sliding assembly 300; the rail assembly 100 includes a left rail 120 and a right rail 110, and the left rail 120 and the right rail 110 are both long groove-shaped, and the groove direction of the left rail 120 is open in a direction away from the right rail 110, and the groove direction of the right rail 110 is open in a direction away from the left rail 120; the sliding assembly 300 includes a base 200 and a roller assembly, The base 200 is arranged above the track assembly 100. The base 200 is provided with downwardly extending baffles 210 on both sides parallel to the left track 120 and the right track 110. The roller assembly is arranged on the baffle 210. The roller assembly includes a bracket 310, a longitudinal roller 330 and a transverse roller 320. The longitudinal roller 330 is arranged at one end of the bracket 310, and the longitudinal roller 330 abuts against the top and bottom surfaces of the left track 120 or the right track 110. The transverse roller 320 is arranged at the other end of the bracket 310, and the transverse roller 320 abuts against the side of the left track 120 or the right track 110. The double tracks are provided to strengthen the load bearing capacity. The double tracks are in the shape of long grooves with the grooves facing outward, which is conducive to increasing the spacing between the rollers of the base 200. Even if the tracks are worn, the tilt change angle of the equipment as a whole is reduced, making the equipment more stable. Secondly, because the longitudinal rollers 330 abut against the left track 120 and the right track 110 at the same time, when one side of the track is under heavy pressure, the longitudinal rollers 330 of the other side of the track will abut against the top surface of the track to share the load. At the same time, the transverse rollers 320 can limit the lateral movement of the base 200, so that the roller assembly maintains a spacing from the left track 120 and the right track 110, limiting the left and right swinging of the sliding device, so that the force of the entire double-groove steel track sliding device is more balanced and stable, and it can withstand a higher load.

[0027] In one embodiment, the base 200 may include four roller assemblies. The base 200 is provided with two roller assemblies on the left track 120 and the right track 110 respectively. The roller assemblies provided at the four corners of the base 200 are conducive to maintaining the balance and stability of the sliding device on the track. It can be understood that the base 200 can be provided with more roller assemblies, such as 6, 8, 10, etc., according to actual needs.

[0028] In one embodiment, the roller assembly may include: the roller assembly is in the same track, one end of the roller assembly with a transverse roller 320 is close to another end of the roller assembly with a transverse roller 320, or; the roller assembly is in the same track, one end of the roller assembly with a longitudinal roller 330 is close to another end of the roller assembly with a longitudinal roller 330, or; the roller assembly is in the same track, one end of the roller assembly with a longitudinal roller 330 is close to another end of the roller assembly with a transverse roller.

[0029] It can be understood that when the base 200 is small in size, the roller assembly is generally arranged in the same track, with one end of the roller assembly having a transverse roller 320 close to the other end of the roller assembly having a transverse roller 320. Because the longitudinal rollers 330 are the main load wheels, arranging them around them is beneficial to improving the force balance and avoiding tipping due to unbalanced force at both ends caused by the load wheels being concentrated in the middle of the base 200; when the base 200 is large in size, any of the three roller assembly arrangements can be selected.

[0030] In one embodiment, the roller assembly may include: the rollers in the left track 120 and the right track 110 are symmetrically arranged, and the supporting points of the base 200 are relatively uniform and neat, which is easy to balance and adjust, thereby improving the stability of the movement of the double-slot steel track sliding device.

[0031] In one embodiment, the roller assembly may include a longitudinal roller 330 that is a double-wheel combination structure. When worn, usually only local wear will occur on the roller, such as near the edge portion, which will gradually become rounded, etc., which will reduce the roller's load-bearing capacity, while the other roller will not be affected, greatly improving the service life and lowering the replacement cost.

[0032] In one embodiment, the baffle 210 may include a protrusion 212 provided on the baffle 210, the protrusion 212 abutting against the upper part of the roller group, and the protrusion 212 extending from the baffle 210 toward the roller assembly. The roller assembly is mainly loaded on its upper part rather than the side. This can prevent the base 200 and the roller assembly from moving relative to each other when the base 200 is subjected to a large load. If only the side is connected, relative displacement may occur after wear when subjected to a large load, affecting the assembly accuracy and further affecting the detection accuracy of the CCTV equipment.

[0033] In one embodiment, the base 200 may include: an annular boss 220 is provided on the upper portion of the base 200, and a through hole 221 is provided inside the boss 220. The annular boss 220 is used to fix a manipulator or other equipment, and the through hole 221 is used to install and fix the manipulator or other equipment with screws.

[0034] In one embodiment, the roller assembly may include: the roller assembly is connected to the baffle 210 via bolts 211. Of course, other connection and fixing methods may also be used, such as gluing, welding, etc.

[0035] See also Figures 4 to 6 In one embodiment, a double-channel steel rail sliding device may include two longitudinal rollers 330 , and the two longitudinal rollers 330 are respectively abutted against the top surface and the bottom surface of the left rail 120 or the right rail 110 .

[0036] In one embodiment, the roller assembly may include gaskets 331 on both sides of the longitudinal roller 330 , and the gaskets 331 can prevent the longitudinal roller 330 from directly contacting the bracket 310 , thereby avoiding friction between the sides of the longitudinal roller 330 and the bracket 310 .

[0037] In one embodiment, the roller assembly may include: the transverse roller 320 is also provided with a roller shaft 321 and a retaining ring 322. The roller shaft 321 passes through one side of the bracket 310 to the other side, and the transverse roller 320 passes through the roller shaft 321. The other end of the roller shaft 321 is fixed by the retaining ring 322. The user only needs to remove the retaining ring 322 to take out the roller shaft 321, which is convenient for disassembly of the transverse roller 320 and thus convenient for disassembly and assembly of the double-slot steel track sliding device.

[0038] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
