Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and particularly relates to a combined bus duct with an interlayer anti-collision structure. Background Art

[0002] A bus duct is a trunk-type and tap-able power supply system for relatively large currents, mostly referring to an intensive bus duct or an enclosed bus duct. It usually consists of a metal shell made of iron or aluminum, a conductor, an insulating material, and related accessories. The copper bars inside are closely arranged together. Through insulation treatment, it can operate safely and stably, and is used to distribute relatively large power to each component of the decentralized system.

[0003] For example, in the patent named "A combined bus duct with an interlayer anti-collision structure" (patent publication number: CN217824154U), a combined bus duct with an interlayer anti-collision structure is disclosed. Through the setting of anti-collision buffer plates and impact buffer mechanisms, when the bus duct encounters an impact, the anti-collision buffer plates on all four sides of the bus duct can provide an additional layer of protection to prevent direct impact on the copper bars. At the same time, when an impact occurs, the anti-collision buffer plates at the impact site will compress the buffer springs in the impact buffer mechanism, and the buffer springs will deform to absorb the huge energy at the moment of impact, preventing the combined anti-collision box from being damaged, but it is difficult to effectively protect the corners of the bus duct.

[0004] Therefore, it is very necessary to propose a combined bus duct with an interlayer anti-collision structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined bus duct with an interlayer anti-collision structure to solve the problem of difficult effective protection of the corners of the bus duct.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A combined bus duct with an interlayer anti-collision structure, including a bus duct housing. Both ends of the bus duct housing are fixedly connected with positioning boxes, and the positioning boxes are located at the corners of the bus duct housing. An elastic air cylinder is arranged between the two positioning boxes. A rotating tube penetrates through the elastic air cylinder, and the rotating tube is fixedly connected with the elastic air cylinder. The rotating tube is rotatably connected between the two positioning boxes. A buffer mechanism is arranged between the elastic air cylinder and the rotating tube. The buffer mechanism includes an outer plate, a first spring, and an inner plate. The outer plate is fixedly connected to the inner wall of the elastic air cylinder, the inner plate is fixedly connected to the outer wall of the rotating tube, one end of the first spring is fixedly connected to the outer plate, and the other end of the first spring is fixedly connected to the inner plate.

[0007] Preferably, multiple groups of the buffer mechanisms are provided, and the multiple groups of buffer mechanisms are evenly distributed around the rotating tube.

[0008] Preferably, a plurality of circular grooves are formed in the rotating pipe, and the rotating pipe is communicated with the elastic air cylinder through the circular grooves and is also communicated with the positioning box.

A second spring is fixedly connected to the side of the sliding plate facing away from the rotating pipe, and the end of the second spring away from the sliding plate is fixedly connected to the inner wall of the cylinder. A limiting rod is fixedly connected to the side of the sliding plate facing the rotating pipe, and the limiting rod is in abutting cooperation with the rotating pipe.

[0010] Preferably, air holes are formed at one end of the cylinder away from the positioning box.

[0011] Preferably, the elastic air cylinder sequentially includes a support layer, a reinforcement layer, and a wear-resistant layer from the inside to the outside.

[0012] Preferably, a plurality of conductive copper bars are arranged inside the busbar housing.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a combined busway Figures 1 to 6 as shown, with a sandwich anti-collision structure, including a busway housing 1, and a plurality of conductive copper bars 14 are arranged inside the busway housing 1. Positioning boxes 2 are fixedly connected to both ends of the busway housing 1, and the positioning boxes 2 are located at the corners of the busway housing 1. An elastic air cylinder 3 is arranged between the two positioning boxes 2. A rotating pipe 4 passes through the elastic air cylinder 3, and the rotating pipe 4 is fixedly connected to the elastic air cylinder 3. The rotating pipe 4 is rotatably connected between the two positioning boxes 2. During specific use, the positioning box 2 together with other structures can be installed at the corners of the busway housing 1 in a combined manner, especially on the side that is easily impacted, or can also be installed at multiple corners. For example, in a factory workshop, when an operator carries a tubular workpiece obliquely on the shoulder, the tubular workpiece is likely to collide with the corners of the busway housing 1 inadvertently.

[0025] At the same time, since the elastic air cylinder 3 protrudes from the busway housing 1, even a frontal collision can be cushioned.

[0026] The elastic air cylinder 3 sequentially includes a support layer 15, a reinforcement layer 16, and a wear-resistant layer 17 from the inside to the outside. The support layer 15, the reinforcement layer 16, and the wear-resistant layer 17 are thermally bonded together. The support layer 15 can use but is not limited to natural rubber materials to enhance the tear resistance, aging resistance, etc. of the elastic air cylinder 3; the reinforcement layer 16 can use but is not limited to fiber reinforcement materials, such as carbon fiber, etc., to enhance the service strength of the rubber of the elastic air cylinder 3; the wear-resistant layer 17 can use but is not limited to TPU materials to enhance the wear resistance of the rubber of the elastic air cylinder 3. By setting the support layer 15, the reinforcement layer 16, and the wear-resistant layer 17 to form a sandwich structure, the service performance of the elastic air cylinder 3 is improved.

[0027] A buffer mechanism is provided between the elastic air cylinder 3 and the rotating pipe 4. The buffer mechanism includes an outer plate 6, a first spring 7, and an inner plate 8. The outer plate 6 is fixedly connected to the inner wall of the elastic air cylinder 3, the inner plate 8 is fixedly connected to the outer wall of the rotating pipe 4, one end of the first spring 7 is fixedly connected to the outer plate 6, and the other end of the first spring 7 is fixedly connected to the inner plate 8. During specific use, a relatively large number of first springs 7 can be provided between the outer plate 6 and the inner plate 8 to improve the shock absorption ability. The buffer mechanism is provided in multiple groups, and the multiple groups of buffer mechanisms are evenly distributed around the rotating pipe 4.

[0028] When an external impact force acts on the elastic air cylinder 3, since the rotating pipe 4 is rotatably connected between the two positioning boxes 2, the elastic air cylinder 3 rotates, dispersing the impact force; when the elastic air cylinder 3 is squeezed, due to the certain elasticity of the elastic air cylinder 3, the force can be unloaded and buffered. At the same time, the outer plate 6 squeezes the first spring 7, and the first spring 7 contracts for a second buffer, realizing the protection of the busbar trunking housing 1.

[0029] By providing structures such as the positioning box 2, the elastic air cylinder 3, the rotating pipe 4, and the buffer mechanism, and installing them at the corners of the busbar trunking housing 1 in a grouped manner. At the same time, the elastic air cylinder 3 is rotatably arranged, so that the impact force is dispersed and multiple force unloading and buffering can be carried out, realizing the protection of the busbar trunking housing 1.

[0030] A plurality of circular grooves 5 are provided on the rotating pipe 4. The rotating pipe 4 is communicated with the elastic air cylinder 3 through the circular grooves 5, and the rotating pipe 4 is communicated with the positioning box 2. When the elastic air cylinder 3 is squeezed, the gas inside it enters the inside of the positioning box 2 through the circular grooves 5 and the rotating pipe 4.

[0031] One side of the positioning box 2 facing away from the rotating pipe 4 is communicated with a cylinder 9. A sliding plate 11 is slidably connected inside the cylinder 9. A second spring 12 is fixedly connected to the side of the sliding plate 11 facing away from the rotating pipe 4. One end of the second spring 12 far from the sliding plate 11 is fixedly connected to the inner wall of the cylinder 9. An air hole 10 is provided at one end of the cylinder 9 far from the positioning box 2. A limiting rod 13 is fixedly connected to the side of the sliding plate 11 facing the rotating pipe 4, and the limiting rod 13 is in abutting cooperation with the rotating pipe 4.

[0032] Specifically, when the elastic air cylinder 3 is squeezed, the gas inside it enters the inside of the positioning box 2 through the circular grooves 5 and the rotating pipe 4, and squeezes the sliding plate 11 to slide in a direction away from the rotating pipe 4, causing the second spring 12 to contract, also achieving a buffering effect; and the gas at one end of the cylinder 9 close to the second spring 12 is discharged through the air hole 10.

[0033] When the sliding plate 11 slides in a direction away from the rotating pipe 4, the end of the limiting rod 13 leaves the rotating pipe 4, without affecting the rotation of the rotating pipe 4.

[0034] After the external impact force disappears, the elastic air cylinder 3 resumes deformation under the reset elastic force of structures such as the second spring 12 and the first spring 7, which is convenient for subsequent use. The end of the limit rod 13 abuts against the rotating tube 4, preventing the rotating tube 4 and the elastic air cylinder 3 from rotating randomly in the non-use state, reducing wear and avoiding noise generation.
