Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to an active pulling anti-slip device for a train. Background Art

[0002] In recent years, with the substantial increase in railway train speed, operating density, and load carrying capacity, higher requirements have been placed on ensuring railway transportation safety. Among these, the most important and critical requirements include the research on anti-skid protection technology and devices for trains.

[0003] At present, the operating conditions of train formation, stations, lines, etc. are diversified, making the anti-skid operation of trains complicated and changeable, especially the increase in the weight carried by trains and the increase in speed, which adds new difficulties to the train's stay. The main anti-skid operation methods still remain in the technical means of iron shoes, manual brakes (fasteners), wheel stoppers and anti-skid sleepers. These technical means have a common feature, that is, they are all installed on the side of the train with a tendency to skid, and the friction resistance between them and the rails is used to achieve the purpose of preventing skidding. For example, the most widely used iron shoe is installed between the track and the wheel to form a wedge support. Due to the influence of multiple factors such as train load, road inclination, strong wind, rain, snow and vibration, once the iron shoe becomes loose or becomes unstable, it is very easy to cause a skidding accident. Therefore, the utility model proposes an active traction anti-skid equipment for trains to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the present invention proposes an active pulling anti-skid device for a train, which is easy to operate, less affected by environmental factors, safe, reliable and has good stability.

[0006] The wheel caliper includes a right branch and a left branch of the wheel caliper. The left branch of the wheel caliper is rotatably mounted on the right branch of the wheel caliper and is self-lockingly fixed. The right branch and the left branch of the wheel caliper clamp the wheel. The rail clamp device includes a left rail block, a right rail block and a wedge block. The upper ends of the left and right rail blocks are connected to each other and clamped on the vehicle rails. The wedge block is arranged between the upper inner side of the left and right rail blocks and the vehicle rails. The top of the wedge block is inclined, and a hook body is provided at one end of the wedge block. The traction rope connects the hook body and the right branch of the wheel caliper.

The traction rope 2 connects the wheel clamp 1 and the rail clamp device 3. The rail clamp device 3 is used to clamp on the rail 4. The wheel clamp 1 is used to clamp the wheel 5.

[0027] The wheel caliper 1 includes a right branch 6 and a left branch 7 of the wheel caliper.

The upper ends of the left rail block 8 and the right rail block 9 are connected to each other and clamped on the vehicle rail 4. The wedge block 10 is arranged between the inner upper side of the left rail block 8 and the right rail block 9 and the vehicle rail 4. The top of the wedge block 10 is inclined, and a hook body 11 is provided at one end of the wedge block 10. The traction rope 2 connects the hook body 11 and the right branch 6 of the wheel caliper. When in use, the device is installed on the side away from the tendency of the train to slip, the wheel 5 is clamped by the wheel clamp 1, and the wheel is clamped on the rail 4 by the rail clamp device 3. The wheel clamp 1 and the rail clamp device 3 are connected by the traction rope 2. The wedge block 10 of the rail clamp device 3 is fixed to the left rail block 8 and the right rail block 9 along the length direction of the rail. Due to the inclined surface of the top of the wedge block 10, when it is pulled by the traction rope 2, it is displaced and squeezes the rail 4 to generate friction force toward the hook body 11, upward and inward, so that the device is self-locking, easy to operate, less affected by environmental factors, safe and reliable, and has good stability.

[0028] The right branch 6 and the left branch 7 of the caliper are rotatably mounted via a caliper pin 12. A mounting groove is provided at one end of the interior of the left branch 7 of the caliper, and a stopper 14 is rotatably provided inside the mounting groove via an elastic cylindrical pin 13. One end of the stopper 14 is provided with a pointed protrusion 15, and one end of the inner side of the right branch 6 of the caliper is provided with a slot 16 that matches the pointed protrusion 15. A straight-arm torsion spring 17 is provided on the elastic cylindrical pin 13, one end of which is supported on the inner side of the stopper 14, and the other end of the straight-arm torsion spring 17 is supported on one end of the interior of the mounting groove. When in use, the right branch 6 of the wheel caliper and the left branch 7 of the wheel caliper are rotatably installed through the wheel caliper pin 12. When the right branch 6 of the wheel caliper and the left branch 7 of the wheel caliper clamp the wheel 5, the tip protrusion 15 of the stopper 14 is stuck in the groove 16 of the right branch 6 of the wheel caliper under the elastic force of the straight arm torsion spring 17, preventing the wheel caliper 1 from falling off. It has the characteristics of high safety and high reliability. One end of the stopper 14 is exposed in the installation groove. When disassembling, it is only necessary to manually move the exposed position of the stopper 14 to unlock the tip protrusion 15 and the groove 16, and then the clamping of the right branch 6 of the wheel caliper and the left branch 7 of the wheel caliper can be opened.

[0029] One end of the right support 6 of the wheel clamp is provided with a threaded groove, and a pin 23 is installed in the internal thread of the threaded groove. The pin 23 is used to connect the traction rope 2. When in use, the device is installed on the side facing away from the tendency of the train to slip. The wheel 5 is clamped by the wheel clamp 1 and clamped on the track 4 by the track clamp 3. The pin 23 and the hook body 11 are connected between the wheel clamp 1 and the track clamp 3 by the traction rope 2.

[0030] The traction rope 2 includes an intermediate protective sleeve 18 and a fiber rope 19. The fiber rope 19 passes through the interior of the intermediate protective sleeve 18, and both ends of the fiber rope 19 are provided with a collar 20. The collar 20 is compatible with the pin 23 and the hook body 11. The traction rope 2 uses a fiber rope 19 with molded collars 20 at both ends. The fiber rope 19 is woven with 12 strands and made of ultra-high molecular weight polyethylene material, which makes the fiber rope 19 light in weight, large in load-bearing capacity, stable in performance and resistant to aging, does not require later maintenance, and is easy to insert and manufacture. The intermediate protective sleeve 18 is added in the middle to protect the fiber rope 19 from wear. Secondly, it increases the diameter of the rope body to make the force on the rope more reasonable. The intermediate protective sleeve 18 can slide in the protective part to ensure that when the installation position on the rail 4 deviates, the force is always the same.

[0031] Example 2

[0032] according to Figure 1 、 2 As shown in Figures 3, 4, 5, 6, and 7, this embodiment provides an active pulling anti-skid device for a train, comprising a wheel clamp 1, a traction rope 2, and a rail clamp device 3. The traction rope 2 connects the wheel clamp 1 and the rail clamp device 3. The rail clamp device 3 is used to clamp on the rail 4. The wheel clamp 1 is used to clamp the wheel 5.

[0033] The wheel caliper 1 includes a right branch 6 and a left branch 7 of the wheel caliper. The left branch 7 of the wheel caliper is rotatably installed on the right branch 6 of the wheel caliper and is self-lockingly fixed. The right branch 6 and the left branch 7 of the wheel caliper clamp the wheel 5. The rail device 3 includes a left rail block 8, a right rail block 9 and a wedge block 10. The upper ends of the left rail block 8 and the right rail block 9 are connected to each other and clamped on the vehicle rail 4. The wedge block 10 is arranged between the inner upper side of the left rail block 8 and the right rail block 9 and the vehicle rail 4. The top of the wedge block 10 is inclined, and a hook body 11 is provided at one end of the wedge block 10. The traction rope 2 connects the hook body 11 and the right branch 6 of the wheel caliper. When in use, the device is installed on the side away from the tendency of the train to slip, the wheel 5 is clamped by the wheel clamp 1, and the wheel is clamped on the rail 4 by the rail clamp device 3. The wheel clamp 1 and the rail clamp device 3 are connected by the traction rope 2. The wedge block 10 of the rail clamp device 3 is fixed to the left rail block 8 and the right rail block 9 along the length direction of the rail. Due to the inclined surface of the top of the wedge block 10, when it is pulled by the traction rope 2, it is displaced and squeezes the rail 4 to generate friction force toward the hook body 11, upward and inward, so that the device is self-locking, easy to operate, less affected by environmental factors, safe and reliable, and has good stability.

[0034] A rail block pin 21 is inserted into the upper end of the left and right rail blocks 8, 9, which are connected to each other.

When in use, the lower edges of the left and right rail blocks 8, 9 are hooked on the lower side of the head of the vehicle rail 4. The hook body 11 of the wedge block 10 is connected to the traction rope 2. When the traction rope 2 is subjected to tension, the wedge block 10 is displaced and squeezes the vehicle rail 4. The pressure generated by the inclined surface of the wedge block 10 generates friction.

[0035] This train's active traction anti-skid device is installed on the side facing away from the train's skidding tendency. It clamps the wheel 5 with a wheel clamp 1 and clamps it onto the track 4 with a track clamp 3. The wheel clamp 1 and track clamp 3 are connected by a traction rope 2. The wedge block 10 of the track clamp 3 is fixed to the left track block 8 and the right track block 9 along the length of the track. Due to the inclined top surface of the wedge block 10, when subjected to the tension of the traction rope 2, it displaces and squeezes the track 4, generating friction toward the hook body 11, upward, and inward, completing the self-locking of the device. It is easy to operate, less affected by environmental factors, safe, reliable, and has good stability. Furthermore, when the right and left branches 6 and 7 of the wheel clamp clamp clamp 5, the tip protrusion 15 of the block 14 is clamped into the slot 16 of the right branch 6 of the wheel clamp clamp under the elastic force of the straight-arm torsion spring 17, preventing the wheel clamp 1 from falling off. This device is characterized by high safety and reliability. Furthermore, this product is lightweight and easy to carry, easy to load and unload, and suitable for a variety of application scenarios.
