[0002] With the acceleration of global urbanization and the improvement of people's demand for travel efficiency, the rail transit industry has ushered in unprecedented development opportunities. However, with the increase in train speed and operation density, the safety and comfort of trains during operation have become the focus of widespread attention within and outside the industry. This is not only related to the travel experience of passengers, but also directly affects the overall operational efficiency and safety of the rail transit system.

[0003] In the design of traditional train hose handshakes, there are often a series of problems that need to be solved urgently. First, the complex structure leads to high manufacturing and maintenance costs. As an important part of the train connection device, the complexity of the structure of the hose handshake not only increases the difficulty of manufacturing, but also brings great challenges to subsequent maintenance work. Secondly, the high connection accuracy requirements make the installation and debugging process cumbersome. The traditional hose handshake design has extremely high requirements for connection accuracy, which not only increases the difficulty of installation and debugging, but also increases the skill requirements for operators. Finally, maintenance difficulties lead to reduced operational efficiency. Due to the complex structure and high connection accuracy requirements, traditional hose handshakes often require a lot of time and manpower during the maintenance process, which not only reduces operational efficiency, but also brings potential risks to the normal operation of the train. Summary of the invention

[0004] The purpose of the present invention is to solve the above deficiencies in the prior art and provide a high-stability train hose handshake based on modular design.

[0005] A high-stability train hose handshake based on modular design, comprising a buffer device, a connecting rod, a center rod, and a height adjustment device, wherein one end of the connecting rod is connected to one end of the center rod, the other end of the center rod is connected to the buffer device, the height adjustment device is connected to the center rod, the height adjustment device comprises a connecting block, a first connecting rod, a second connecting rod, and a telescopic bottom rod, the connecting block is fixedly connected to the center rod, one end of the first connecting rod and the second connecting rod are both hinged on the connecting block, and the rotation axes of the two are parallel and staggered, and the other ends of the first connecting rod and the second connecting rod are respectively connected to the two ends of the telescopic bottom rod;

[0006] The telescopic low rod includes a first sliding rod and a second sliding rod. The first sliding rod and the second sliding rod are parallelly and slidably connected to the upper end surface of the base. The inner surfaces of the first sliding rod and the second sliding rod are both provided with a rack structure. A gear meshing with the rack structure is provided between the first sliding rod and the second sliding rod. The opposite ends of the first sliding rod and the second sliding rod are respectively connected to the first connecting rod and the second connecting rod. A motor is provided in the base, and the output end of the motor is connected to the gear.

[0007] Furthermore, the first sliding rod, the second sliding rod and the upper end surface of the base are connected via a slider guide structure.

[0008] Furthermore, a matching groove is formed on one of the connecting block and the center rod, and a matching protrusion matching with the matching groove is provided on the other of the connecting block and the center rod.

[0009] Furthermore, the matching groove is formed on the central rod, and the matching protrusion is provided on the connecting block.

[0010] Furthermore, the depth of the matching groove is greater than the height of the matching protrusion.

[0011] Furthermore, the cross-sectional area of ​​the connection block is larger than the cross-sectional area of ​​the matching protrusion, and a groove for accommodating at least a portion of the connection block and communicating with the matching groove is formed on the center rod.

[0012] Furthermore, the central rod and the one end of the connecting rod are connected by a pin.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

DETAILED DESCRIPTION

[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0027] like Figure 1-3 As shown, the coupler buffer 100, the connecting rod 1, the center rod 2, the matching grooves 20a, 20b, the groove 20b, the height adjustment device 3, the first connecting rod 31, the second connecting rod 32, the connecting block 33, the first sliding rod 34, the second sliding rod 35, the gear 36, the base 37, the pin 4, the intermediate bearing seat 5, the base 6, the fixing bolt 61, and the rotating device 62;

[0028] A high-stability train hose handshake based on modular design includes a buffer device (not shown), a connecting rod 1, a center rod 2 and a height adjustment device 3.

[0029] One end of the connecting rod 1 is connected to the buffer device, the central rod 2 is connected between the above-mentioned one end of the connecting rod 1 and the buffer device, and the height adjustment device 3 is arranged on the central rod 2.

[0030] For example, Figure 1 As shown, one end of the connecting rod 1 (for example, Figure 1 The right end of the connecting rod 100 is connected to the buffer device through the center rod 2, and the height adjustment device 3 can be arranged at the bottom of the center rod 2 to support the center rod 2 and adjust the height of the center rod 2 in the vertical direction. Therefore, the connecting rod 1 and the height adjustment device 3 are indirectly connected to the buffer device through the center rod 2, thereby simplifying the structure of the coupler buffer 100, and reducing the accuracy requirements of the connection between the connecting rod 1 and the buffer device, and the height adjustment device 3 and the buffer device, thereby reducing the processing cost of the coupler buffer 100.

[0031] Specifically, the other end of the connecting rod 1 (for example, Figure 1 When the height of the coupler needs to be adjusted, the height adjustment device 3 is adjusted first, and the connecting rod 1 is placed in a horizontal state by adjusting the position of the center rod 2. At this time, the breaking bolt (not shown) can be adjusted to make the coupler buffer 100 in a horizontal state, thereby facilitating the adjustment of the height of the coupler and the coupler buffer 100.

[0032] In one embodiment of the present invention, the height adjustment device 3 includes a connecting block 33, a first connecting rod 31, a second connecting rod 32, and a telescopic bottom rod. The connecting block 33 is fixedly connected to the center rod, one end of the first connecting rod 31 and the second connecting rod 32 are both hinged to the connecting block 33, and the rotation axes of the two are parallel and staggered, and the other ends of the first connecting rod 31 and the second connecting rod 32 are respectively connected to the two ends of the telescopic bottom rod;

[0033] The telescopic low rod includes a first sliding rod 34 and a second sliding rod 35. The first sliding rod 34 and the second sliding rod 35 are parallelly and slidably connected to the upper end surface of the base 37. The inner surfaces of the first sliding rod 34 and the second sliding rod 35 are both provided with a rack structure. A gear 36 meshing with the rack structure is provided between the first sliding rod 34 and the second sliding rod 35. The opposite ends of the first sliding rod 34 and the second sliding rod 35 are respectively connected to the first connecting rod 31 and the second connecting rod 32. A motor is provided in the base 37, and the output end of the motor is connected to the gear 36.

[0034] Specifically, the first connecting rod 31, the second connecting rod 32, the telescopic bottom rod, and the connecting block 33 form an isosceles trapezoid. Since they are all hinged, when the length of the telescopic bottom rod is adjusted, the angle between the first connecting rod 31, the second connecting rod 32 and the telescopic bottom rod can be adjusted, thereby adjusting the height of the connecting block 33;

[0035] In addition, the gear 36 is located directly below the connecting block 33, that is, the projection of the center position of the line between the two hinges of the connecting block 33 on the base 37, to ensure that the isosceles trapezoidal structure will not be damaged after the first connecting rod 31 and the second connecting rod 32 move. A gear 36 cover (not shown in the figure) is provided above the gear 36, and the gear 36 cover is fixedly connected to the base 37. A retractable top column (not shown in the figure) is provided on the upper end face of the gear 36 cover, and the top end of the top column is connected to the lower end face of the connecting block 33. The top column is perpendicular to the upper end face of the gear 36 cover and the lower end face of the connecting block 33, and the length of the top column can be locked by a locking structure. After locking, the length of the top column no longer changes.

[0036] It should be noted that the retractable column structure with a locking structure is a prior art, so it will not be described in detail. The locked top column can enhance the supporting effect on the connecting block 33 to prevent structural damage, and the retractable structure can adapt to changes in the height of the isosceles trapezoidal structure.

[0037] In an optional embodiment of the present invention, a matching groove 20a is formed on one of the connecting block 33 and the center rod 2, and a matching protrusion 34 matching with the matching groove 20a is provided on the other of the connecting block 33 and the center rod 2. Thus, the height adjustment device 3 is connected to the center rod 2 through the matching between the matching groove 20a and the matching protrusion 34, which reduces the accuracy of the matching between the height adjustment device 3 and the center rod 2, and has a simple structure and convenient processing, reduces the components of the coupler buffer 100, and thus reduces the cost of the coupler buffer 100.

[0038] Specifically, the matching groove 20a is formed on the center rod 2, and the matching protrusion 34 is provided on the connecting block 33. For example, Figure 1 and Figure 2 As shown, the mating groove 20a can be formed at the bottom of the center rod 2, and the mating groove 20a can be formed by the upward concave lower edge of the center rod 2, and the mating protrusion 34 can be arranged on the upper side of the connecting block 33, and the mating protrusion 34 extends into the mating groove 20a and cooperates with the mating groove 20a to complete the connection between the height adjustment device 3 and the center rod 2, thereby improving the connection efficiency between the height adjustment device 3 and the center rod 2.

[0039] In one embodiment of the present invention, the depth of the matching groove 20a is greater than the height of the matching protrusion 34. For example, the axial depth of the matching groove 20a is greater than the axial height of the matching protrusion 34. When the matching protrusion 34 is matched in the matching groove 20a, an extra matching space can be reserved in the matching groove 20a to avoid the center rod 2 from being damaged during the height adjustment.

[0040] The mating groove 20 a exerts axial pressure on the mating protrusion 34 , thereby protecting the mating protrusion 34 .

[0041] In an optional embodiment of the present invention, the cross-sectional area of ​​the connecting block 33 is larger than the cross-sectional area of ​​the matching protrusion 34, and a groove 20b for accommodating at least part of the connecting block 33 and communicating with the matching groove 20a is formed on the central rod 2. Figure 1 and Figure 2 As shown, the groove 20b is located at the lower side of the matching groove 20a, and the groove 20b can be matched with the upper part of the connecting block 33. When the connecting block 33 and the matching protrusion 34 are coaxially arranged, the groove 20b and the matching groove 20a are also coaxially arranged. Therefore, by setting the connecting block 33, the cross-sectional area of ​​the connecting block 33 is larger than the cross-sectional area of ​​the matching protrusion 34, the supporting effect of the connecting block 33 on the center rod 2 can be improved, and the supporting effect of the connecting block 33 on the center rod 2 can be made reliable; moreover, the at least partial matching of the groove 20b with the connecting block 33 can reduce the lateral shear force generated by the lower end of the matching groove 20a on the matching protrusion 34, thereby improving the lateral shear resistance of the connecting block 33 and the matching protrusion 34.

[0042] In a specific embodiment of the present invention, Figure 1 As shown, the center rod 2 is connected to one end of the connecting rod 1 (for example, Figure 1 The right end in the middle) is detachably connected, and the other end of the connecting rod 1 (for example, Figure 1 The left end of the center rod 2 is connected to the coupler, thereby facilitating the disassembly and assembly between the coupler and the coupler buffer 100 through the disassembly and assembly between the center rod 2 and the connecting rod 1, thereby facilitating the replacement of the coupler.

[0043] Alternatively, if Figure 1 As shown, the center rod 2 and one end of the connecting rod 1 (for example, Figure 1 The right end of the coupler is connected by a pin 4. Thus, the efficiency of assembly and disassembly between the coupler and the coupler buffer 100 is improved, the structure of the coupler buffer 100 is further simplified, the components of the coupler buffer 100 are reduced, and the cost of the coupler buffer 100 is reduced. In addition, the pin 4 connection, such as the conical pin connection, makes the positioning accuracy between the coupler and the coupler buffer 100 high, and avoids the floating and sinking of the coupler during use and assembly and disassembly, so that the coupler buffer 100 can well protect the coupler and extend the service life of the coupler.

[0044] The rail transit system according to the second embodiment of the present invention includes the coupler buffer 100 according to the first embodiment of the present invention. It is understood that the rail transit system can be a train, a subway or a light rail, but is not limited thereto. In the following description of the present application, the coupler buffer 100 is applied to a light rail as an example for explanation.

[0045] When the coupler buffer 100 is applied to a rail transit system such as a light rail, the right end of the center rod 2 can be connected to the body of the rail transit system such as a light rail through a buffer sleeve, a center adjustment device, a collapse device and a fixing bolt 61, wherein the fixing bolt 61 is arranged on a base 6, and an intermediate bearing seat 5 and a rotating device 62 are provided on the base 6. The rotating device 62 can realize automatic centering of the coupler buffer 100. The left end of the connecting rod 1 is connected to the coupler of the rail transit system such as a light rail, thereby buffering the impact force between the above-mentioned body and the coupler, thereby improving the comfort and safety of the rail transit system such as a light rail.

[0046] According to the rail transit system of the embodiment of the present invention, by adopting the above-mentioned coupler buffer 100, the rail transit system has a simple structure and low cost, and can effectively buffer the impact force between the car body and the coupler of the rail transit system, thereby improving the comfort and safety of the rail transit system.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
