However, the braking distance of the existing brake rail is long, and when facing heavy transport vehicles, the heavy transport vehicles cannot be braked at all due to the small braking force.

[0019] In an optional embodiment, the depth of the bevel is 50% to 80% of the depth of the groove.

[0020] Beneficial effect: By setting the depth of the bevel to between 50% and 80% of the groove depth, the pattern segment can be self-checked based on whether the bevel is completely worn out to determine whether it needs to be repaired or replaced.

[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0036] In the related art, the anti-skid device achieves the anti-skid effect by friction braking between the extension and contraction of the brake rail and the roller of the rail vehicle, and maintaining the friction force after the rail vehicle stops. However, the braking distance of the existing brake rail is long, and when facing heavy transport vehicles, the heavy transport vehicles cannot be braked at all due to the small braking force.

[0037] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0038] According to an embodiment of the utility model, on the one hand, a brake rail for preventing slippage from being caused to increase braking performance is provided, such as Figure 1 As shown, it includes a rail body 100 , which includes a connecting portion 10 and a friction portion 20 . The connecting portion 10 is suitable for connecting with the telescopic end of the telescopic drive mechanism; the friction portion 20 is suitable for braking contact with the rail vehicle, and the friction portion 20 includes a pattern segment 201 .

[0039] It should be noted that the pattern segment 201 is provided with a pattern for reducing the contact area to increase the friction coefficient. The shape of the pattern is not limited, as long as it can increase the friction coefficient.

[0040] In this embodiment, a pattern segment 201 is provided on the friction portion 20 on the rail body 100. The pattern segment 201 has a pattern and a large friction coefficient. When the thrust of the telescopic drive mechanism remains unchanged, the braking force of the friction portion 20 on the vehicle can be increased and the braking distance can be shortened, thereby enhancing the braking effect.

[0041] In one embodiment, Figure 1 As shown, the friction portion 20 further includes a plane segment 202 . The plane segment 202 and the pattern segment 201 are arranged in sequence along the height direction of the rail body 100 , and the plane segment 202 is not higher than the height of the pattern segment 201 .

[0042] In this implementation, the plane section 202 and the pattern section 201 are arranged in sequence along the height direction of the rail body 100, and the plane section 202 is not higher than the height of the pattern section 201. When the plane section 202 is flush with the pattern section 201, the vehicle is braked by combining the planar plane section 202 and the pattern section 201, which can meet the braking force while taking into account the wear loss and improve the service life of the brake rail; when the plane section 202 is lower than the pattern section 201, only the pattern section 201 is used for braking friction, and the braking force is maximum at this time.

[0043] In one embodiment, Figure 2 As shown, the rail body 100 includes a rail body 30 and a brake strip assembly 40, and the rail body 30 is suitable for connecting with the telescopic drive mechanism; the brake strip assembly 40 is fixedly connected to the rail body 30 and can be removed, and the pattern segment 201 is located on the brake strip assembly 40, wherein the specific connection method of the brake strip assembly 40 and the rail body 30 is: a receiving groove for installing the brake strip assembly 40 is provided on the rail body 30, and the brake strip assembly 40 is screwed into the receiving groove by bolts. It should be noted that the position of the receiving groove can be located at any position on the rail body 30 along the height direction of the rail body 30, preferably, it is located at a position on the rail body 30 away from the ground, and this position is preferably repaired and replaced by maintenance personnel.

[0044] Of course, in some embodiments not shown, the brake strip assembly 40 may also be connected to the rail body 30 in other detachable ways, such as by providing a slide groove on the rail body 30, and providing a matching slider on the brake strip assembly 40, connecting them by matching the slide groove and the slider, and simultaneously passing the slider and the slide groove through a corresponding limit pin to fix the two together.

[0045] In this embodiment, the tread segment 201 is disposed on the brake strip assembly 40 and is connected to the rail body 30 in a detachable manner, so that the tread segment 201 can be easily replaced after being worn.

[0046] In one embodiment, Figure 2 As shown, the brake strip assembly 40 includes a plurality of brake strip segments 401 sequentially arranged along the length direction of the rail body 30. Specifically, the length of the brake strip segment 401 can be selected according to actual needs, such as a length of 50 cm to 120 cm, preferably 80 cm;

[0047] In this embodiment, the brake strip assembly 40 includes a plurality of brake strip segments 401 sequentially arranged along the length direction of the rail body 30 , which can facilitate parts manufacturing, transportation and installation.

[0048] In one embodiment, the brake strip assembly 40 is a high temperature and wear resistant brake strip, specifically: the brake strip segment 401 is cast into a base using high temperature and wear resistant materials (such as powder metallurgy brake materials, etc.), the pattern can be directly cast and then subjected to subsequent treatments such as rust prevention.

[0049] In this embodiment, the brake strip assembly 40 is a high temperature resistant and wear resistant brake strip, that is, it is made of high temperature resistant and wear resistant material, which can increase the service life of the brake strip assembly 40.

[0050] In one embodiment, Figures 1-2 As shown, the pattern segment 201 is provided with a plurality of grooves at intervals along the length direction of the rail body 100 , and a trapezoidal protrusion 2011 is formed between any two adjacent grooves.

[0051] In this embodiment, a plurality of spaced grooves are provided on the friction portion 20 to form a trapezoidal protrusion 2011. The processing method is simple, and the trapezoidal protrusion 2011 has high stability, is not prone to breakage, and has a long service life. The surface of the trapezoidal protrusion 2011 is a plane.

[0052] In some embodiments not shown, by providing a plurality of spaced grooves on the friction portion 20, bosses of other shapes such as rectangular bosses, square bosses, and parallelogram bosses may be formed, as long as they can be easily processed or cast.

[0053] In one embodiment, Figures 1-2 As shown, the edge of the trapezoidal protrusion 2011 is provided with an oblique angle 2012 .

[0054] In this implementation, the setting of the bevel 2012 can reduce stress concentration, reduce the damage probability of the trapezoidal protrusion 2011, and increase the service life of the brake rail.

[0055] In a specific embodiment, the depth of the bevel 2012 is 50% to 80% of the groove depth. In this implementation, by setting the depth of the bevel 2012 to between 50% and 80% of the groove depth, the pattern segment 201 can be self-checked based on whether the bevel 2012 is completely worn out to determine whether it needs repair or replacement.

[0056] In the second aspect, the utility model also provides an anti-slip device, such as Figure 3 As shown, it includes a telescopic driving mechanism and an anti-skid brake rail for increasing braking performance as in any one embodiment of the first aspect, and the connecting part 10 is connected to the telescopic end of the telescopic driving mechanism.

[0057] Specifically, the anti-slip device includes two anti-slip device brake rails for increasing braking performance, the friction parts 20 of the two anti-slip device brake rails for increasing braking performance are arranged back to back, and multiple driving screws are arranged side by side and spaced along the length direction of the anti-slip device brake rails for increasing braking performance between the two anti-slip device brake rails for increasing braking performance, and the telescopic walls at both ends of the multiple driving screws are respectively connected to the anti-slip device brake rails for increasing braking performance, so as to simultaneously drive the two telescopic walls to move relative to each other or run back to back, and the multiple driving screws are connected to the driving motor through the driving shaft, and the multiple driving screws, the driving shaft and the driving motor constitute a telescopic driving mechanism.

[0058] It should be noted that "back to back" means back to back.

[0059] In this embodiment, because the anti-skid device includes the anti-skid device brake rail for increasing the braking performance, it has the same effect as the anti-skid device brake rail for increasing the braking performance, and will not be described in detail here.

[0060] In a third aspect, the utility model further provides a track, comprising the anti-slip device as in the second aspect.

[0061] It should be noted that the track may be a train track, a tram track, a city subway or light rail track, etc.

[0062] In this embodiment, because the track includes an anti-slip device, it has the same effect as the anti-slip device and is not described in detail here.

[0063] The following describes the application scenario of the anti-skid brake rail for increasing the braking performance in combination with the solutions in the above embodiments:

[0064] (1) The brake strip segment 401 is cast from powder metallurgy brake material, and a wear-resistant layer may be provided on its surface;

[0065] (2) A mounting groove is provided at the upper edge of the rail body 30, and a plurality of brake strip segments 401 are screwed into the mounting groove by bolts, and the height of the pattern segment 201 on the brake strip segment 401 is kept flush with the height of the plane segment 202 on the anti-slip brake rail for increasing the braking performance, wherein both ends and the middle of the brake strip segment 401 are screwed to the rail body 30 by bolts;

[0066] (3) Install the anti-slip device at the position where the train needs to stop, wherein the brake rail on the anti-slip device adopts the anti-slip device brake rail with increased braking performance;

[0067] (4) When the train arrives at the designated position, the control center controls the anti-slip device to perform braking action, specifically: the driving motor drives multiple driving screws through the driving shaft at the same time, so that the telescopic walls on both sides of the driving screws extend outward at the same time, so that the anti-slip device brake rail that increases the braking performance contacts and rubs with the braking part on the train, and the pattern segment 201 and the plane segment 202 on the anti-slip device brake rail that increases the braking performance simultaneously contact and rub with the braking part on the train to brake until the train stops, and then ensure the corresponding braking holding force to prevent the train from slipping. Before the train starts, the control center controls the anti-slip device to move, so that the anti-slip device brake rail that increases the braking performance is separated from the braking part on the train, and then the train is started. During the braking process, due to the presence of the pattern segment 201, the braking force will be increased, thereby reducing the braking distance and improving the braking effect;

[0068] (5) After a certain period of use, the brake strip segment 401 needs to be regularly inspected for wear. When it is found that the bevel 2012 of the trapezoidal protrusion 2011 on the brake strip segment 401 is completely worn and the non-bevel 2012 part begins to wear, the brake strip segment 401 needs to be replaced with a new one.

[0069] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
