Description

Technical Field

[0001] The utility model relates to the field of brake systems, in particular to an air brake device for electric locomotives. Background Art

[0002] The air brake device is one of the most important components of an electric locomotive. It carries the braking, relief and operation performance of the locomotive. Its good performance is related to the safety of vehicle operation.

[0003] The air in the air brake device is generally transmitted through the brake pipe, and the brake pipe is generally fixed to the bottom of the electric locomotive by a clamp. However, when the existing clamp is used to clamp the brake pipe, the inner walls of the upper pipe clamp and the lower pipe clamp are smooth. Therefore, when they abut against the outer wall of the brake pipe, the friction is small, which causes the brake pipe to slide easily and the clamping is not firm. Moreover, the upper pipe clamp and the lower pipe clamp are directly locked and fixed by bolts. When the torque between the upper pipe clamp and the lower pipe clamp is large, it is easy to cause the bolts to break, which will also affect the stability of the key clamp. Utility Model Content

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. The elastic convex teeth arranged on the inner wall of the clamp abut against the outer wall of the brake pipe, thereby improving the clamping effect of the pipe clamp. Then, by turning the countersunk screw, the second clamping block is clamped relative to the first clamping block, thereby effectively increasing the friction between the pipe clamp and the pipe, preventing the pipe from moving, and improving the stability of the pipe clamp.

DETAILED DESCRIPTION

[0025] The following combination Figures 1-6 The utility model is described in further detail.

[0026] This embodiment discloses an electric locomotive air brake device: Figures 1-6 An electric locomotive air brake device includes a bracket 10, an air compression module 20, a brake module 30, a brake main pipe module 40, a pipe clamp 50 and a connecting assembly 60;

[0027] The brake main pipe module 40 includes a plurality of brake pipes 41 , and the pipe clamp 50 is sleeved on the brake pipes 41 . The pipe clamp 50 is mounted on the bracket 10 via a connecting assembly 60 .

[0028] The pipe clamp 50 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 is provided with a first guide groove 511, and the second clamping block 52 is provided with a second guide groove 521. A clamping plate 53 is installed in the first guide groove 511 and the second guide groove 521. The inner wall of the clamping plate 53 is integrally formed with a convex tooth 531. The first clamping block 51 and the second clamping block 52 are both provided with a threaded hole 54. A countersunk screw 55 is inserted between the first clamping block 51 and the second clamping block 52 through the threaded hole 54. A plurality of limit rods 512 are provided on the first clamping block 51, and a plurality of limit grooves 522 are provided on the second clamping block 52.

[0029] When installing the brake pipe 41, the clamping plate 53 is installed after the first guide groove 511 and the second guide groove 521, and then the limiting rod 512 set at the bottom end of the first clamping block 51 is inserted into the inner side of the limiting hole set at the top end of the second clamping block 52, so as to facilitate the quick docking between the first clamping block 51 and the second clamping block 52. At the same time, after the first clamping block 51 and the second clamping block 52 are fixed together by the countersunk screw 55, the torsional resistance of the countersunk screw 55 can be effectively improved to prevent the countersunk screw 55 from breaking. At the same time, the elastic convex teeth 531 set on the inner wall of the clamping plate 53 are in contact with the outer wall of the brake pipe 41, and then the second clamping block 52 is clamped relative to the first clamping block 51 by rotating the countersunk screw 55, thereby effectively increasing the friction between the pipe clamp 50 and the pipe, preventing the pipe from moving, and improving the stability of the pipe clamp 50.

[0030] Reference Figure 1-Figure 3 The air compression module 20 includes an air tank 22 and an air compressor 21. The air compressor 21 and the air tank 22 are both arranged on the bracket 10. The air compressor 21 is connected to the air tank 22 through a brake pipe 41; the air tank 22 is provided with a safety valve 221 and a pressure gauge 222.

[0031] The compressed air generated by the air compressor 21 is stored in the air tank 22 through the brake pipe 41. The air compressor 21 is used to compress the gas, and the air tank 22 is used to store the compressed gas. The pressure gauge 222 is used to facilitate the staff to observe the air pressure in the air tank 22. If the air pressure is too high, the safety valve 221 can be opened to exhaust. On the one hand, the air pressure in the air tank 22 is too high and an explosion occurs.

[0032] Reference Figure 3The brake module 30 includes a brake 33, a brake cylinder 32 and a brake valve 31. The cylinder and the brake valve 31 are arranged on the bracket 10. The air tank 22 is connected to the brake cylinder 32 through a brake pipe 41. The brake valve 31 is arranged on the brake pipe 41 between the air tank 22 and the brake cylinder 32. The driving end of the brake cylinder 32 is connected to the brake 33.

[0033] The brake 33 is set at the wheel. When the brake valve 31 is opened, the compressed air in the air tank 22 enters the brake cylinder 32, pushing the driving end of the brake cylinder 32 to move, so that the brake 33 tightly hugs the wheel and brakes.

[0034] Reference Figure 4 The limiting grooves 522 are arranged on both sides of the threaded hole 54, and the threaded hole 54 is arranged on both sides of the clamping plate 53. The second clamping block 52 is fixedly connected to the connecting plate 523, and a plurality of first bolts 524 are arranged on the connecting plate 523.

[0035] The limiting grooves 522 are arranged on both sides of the threaded hole 54, so that the limiting rod 512 can limit the relative installation between the first clamping block 51 and the second clamping block 52 through the limiting groove 522, thereby strengthening the limiting effect of the limiting rod 512 and further improving the torsion resistance of the countersunk screw 55; the threaded holes 54 are arranged on both sides of the clamping plate 53, so that the countersunk screw 55 can be fixed on both sides between the first clamping block 51 and the second clamping block 52, thereby enhancing the fixing effect; the setting of the connecting plate 523 and the first bolt 524 makes it convenient for users to install the pipe clamp 50.

[0036] Reference Figure 4-Figure 5 The connecting assembly 60 includes a first mounting column 61 and a second mounting column 62. The connecting plate 523 is connected to the first mounting column 61 through a plurality of first bolts 524. The second mounting column 62 is arranged on the bracket 10. The surface of the first mounting column 61 is provided with through holes 611 distributed in a linear array. A second bolt 621 is provided on one side of the second mounting column 62, and the second bolt 621 is adapted to the through hole 611.

[0037] When the bracket 10 is far away from the brake pipe 41, the surface of the second mounting column 62 is provided with through holes 611 distributed in a linear array. By limiting the position quota of the bolts and the through holes 611, the extension distance of the second mounting column 62 relative to the first mounting column 61 can be controlled to adjust the length of the entire device; it has the function of highly adaptable installation.

[0038] Reference Figure 6 The connecting assembly 60 includes an elastic pad 63 , and the screw portion of the first bolt 524 passes through the connecting plate 523 and the elastic pad 63 and is rotatably disposed on the bracket 10 .

[0039] When the distance between the bracket 10 and the brake pipe 41 is relatively close, an elastic pad 63 can be added in the gap between the connecting plate 523 and the bracket 10, so that the screw portion of the first bolt 524 passes through the connecting plate 523 and the elastic pad 63 and is rotated and set on the bracket 10. Therefore, the setting of the elastic pad 63 makes it convenient for the user to install the pipe clamp 50 on the bracket 10.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
