Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to an aluminum profile for rail transit that is easy to traction. Background Technology

[0002] Rail transit aluminum profiles mainly refer to large hollow aluminum alloy profiles used to manufacture train bodies. They are mainly made of 6000 series aluminum alloy and are formed in one piece through high-temperature extrusion. Their core advantages are high strength and lightweight. They adopt a thin-walled multi-cavity structure, which significantly reduces the weight of the car body while ensuring load-bearing capacity and rigidity, thereby reducing operating energy consumption and improving transportation efficiency.

[0003] The existing rail transit aluminum profile traction mainly uses a double-headed relay traction machine, which uses hydraulic drive to complete the traction operation. However, the structure is relatively complex, and multiple parts need to work together during the traction process. The failure rate is high, and it relies on manual adjustment for a long time, which affects the stability of traction and makes the efficiency of traction of aluminum profiles low.

[0004] Therefore, those skilled in the art have provided a rail transit aluminum profile that is easy to traction, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rail transit aluminum profile that is easy to traction, thereby improving the traction efficiency of the aluminum profile body and extending its service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rail transit aluminum profile that is easy to pull includes an aluminum profile body and a traction component. Threaded grooves are provided on both sides of the aluminum profile body near the front end. The traction component is located directly in front of the aluminum profile body.

[0008] The traction assembly includes a traction block, two arc-shaped extrusion blocks, and two bearing seats. Connecting plates are fixedly installed on both sides of the rear end face of the traction block. Rotating rods are rotatably sleeved on the inner sides of the two bearing seats. Torsion springs are sleeved on both sides of the two rotating rods. Arc-shaped openings are opened on opposite sides of the rear ends of the two arc-shaped extrusion blocks. A gasket is fixedly installed in the middle of the front end face of the traction block. A semi-circular groove is opened in the middle of the front end face of the gasket.

[0009] The aluminum profile body includes a base layer and multiple reinforcing ribs. A reinforcing layer is fixedly disposed on the outside of the base layer, a treatment layer is fixedly disposed on the outside of the reinforcing layer, and an outer layer is fixedly disposed on the outside of the treatment layer.

[0010] Furthermore, the two arc-shaped extrusion blocks are respectively fixedly sleeved around the rotating rod, and connection holes are opened in the middle of both sides of the two connecting plates.

[0011] Furthermore, the four torsion springs are fixed in pairs on both sides of the two arc-shaped extrusion blocks.

[0012] Furthermore, the base layer is made of aluminum alloy, and the reinforcing ribs are made of glass fiber.

[0013] Furthermore, the reinforcing layer is made of aramid fiber reinforced composite material, and the treatment layer undergoes chromium-free conversion treatment.

[0014] Furthermore, the outer layer is made of a chromium oxide ceramic coating.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a rail transit aluminum profile that is easy to pull. When the aluminum profile body of the traction component is pulled, the operation efficiency and stability are greatly improved, and the detachment during the traction process is prevented.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 One embodiment of this utility model is a rail transit aluminum profile that is easy to pull, including an aluminum profile body 1 and a traction component 2. Threaded grooves 3 are opened on both sides of the aluminum profile body 1 near the front end, and the traction component 2 is located in front of the aluminum profile body 1.

[0027] Specifically, by setting threaded grooves 3 in the middle of both sides of the aluminum profile body 1 near the front end, the installation bolts pass through the connecting holes 202 opened in the connecting plate 201 of the traction assembly 2 and are then threaded into the threaded grooves 3, which facilitates the installation and removal of the traction assembly 2 on the aluminum profile body 1. Since the traction assembly 2 is located at the front end of the aluminum profile body 1, the traction assembly 2 improves the efficiency and stability of the aluminum profile body 1 in traction.

[0028] Reference Figures 1-4 The traction assembly 2 includes a traction block 203, two arc-shaped extrusion blocks 207 and two bearing seats 206. A connecting plate 201 is fixedly installed on both sides of the rear end face of the traction block 203. A rotating rod 2010 is rotatably sleeved on the inner side of each of the two bearing seats 206. Torque springs 209 are sleeved on both sides of the two rotating rods 2010. An arc-shaped opening 208 is opened on the opposite side of the rear end of each of the two arc-shaped extrusion blocks 207. A gasket 204 is fixedly installed in the middle of the front end face of the traction block 203. A semi-circular groove 205 is opened in the middle of the front end face of the gasket 204.

[0029] Two arc-shaped extrusion blocks 207 are fixedly sleeved around the rotating rod 2010. Two connecting plates 201 have connecting holes 202 in the middle of both sides. Four torsion springs 209 are fixed in pairs on both sides of the two arc-shaped extrusion blocks 207.

[0030] Specifically, the connecting block at the rear end of the traction block 203 can slide easily on both sides of the aluminum profile body 1, facilitating the installation and removal of the traction assembly 2 from the aluminum profile body 1. The rotating rod 2010 inside the bearing seat 206 allows the arc-shaped extrusion block 207 to be fixedly sleeved around the rotating rod 2010. The torsion spring 209 sleeved around the rotating rod 2010 is fixed on both sides of the arc-shaped extrusion block 207, allowing the arc-shaped extrusion block 207 to rotate and return to its original position after being extruded. The semi-circular groove 205 at the front of the gasket 204 and the arc-shaped opening 208 at the rear end of the arc-shaped extrusion block 207 allow the traction rod to fit around the traction rod when it makes small displacements between the arc-shaped extrusion block 207 and the gasket 204, improving the traction efficiency and stability of the aluminum profile body 1.

[0031] Reference Figure 1 , Figure 5 The aluminum profile body 1 includes a base layer 101 and multiple reinforcing ribs 102. A reinforcing layer 103 is fixedly provided on the outside of the base layer 101, a treatment layer 104 is fixedly provided on the outside of the reinforcing layer 103, and an outer layer 105 is fixedly provided on the outside of the treatment layer 104.

[0032] The base layer 101 is made of aluminum alloy, the reinforcing rib 102 is made of glass fiber, the reinforcing layer 103 is made of aramid fiber reinforced composite material, the treatment layer 104 is chromium-free conversion treatment, and the outer layer 105 is made of chromium oxide ceramic coating.

[0033] Specifically, by uniformly placing reinforcing ribs 102 inside the base layer 101, the reinforcing ribs 102 are made of glass fiber, and the reinforcing layer 103 is made of aramid fiber reinforced composite material. The reinforcing ribs 102 and the reinforcing layer 103 improve the strength and rigidity of the aluminum profile body 1, as well as its impact resistance. The treatment layer 104 is a chromium-free conversion treatment, forming a conversion film with good corrosion resistance and effectively preventing corrosive media. The outer layer 105 is made of chromium oxide ceramic coating, forming a protective layer with extremely high hardness and wear resistance to resist severe abrasive wear. The internal structure of the aluminum profile body 1 improves the service life of the aluminum profile body 1.

[0034] Working principle: The aluminum profile body 1 is fixedly connected to the traction component 2. Bolts pass through the connecting holes 202 on the connecting plate 201, and the bolts are threaded into the threaded grooves 3 on the aluminum profile body 1 to facilitate the installation and removal of the traction component 2. When traction is applied, the traction rod is pressed against the arc-shaped pressing block 207 around the rotating rod 2010. The rotating rod 2010, which is rotated and sleeved inside the bearing seat 206, drives the arc-shaped pressing block 207 to rotate backward, so that the traction rod is pressed into the semi-circular groove 205 of the pad 204. The arc-shaped pressing block 207 is reset by the torsion springs 209 on both sides, blocking the traction rod between the arc-shaped pressing block 207 and the pad 204. The traction rod makes a small displacement between the semi-circular groove 205 on the pad 204 and the arc-shaped opening 208 behind the arc-shaped pressing block 207 to prevent the traction rod from falling off, thereby stabilizing the aluminum profile body 1 and improving the traction efficiency.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
