Description

Technical Field

[0001] The invention belongs to the technical field of monorail vehicles, and more specifically, relates to a transition coupler structure of a monorail vehicle. Background Art

[0002] With the increasing traffic pressure in small and medium-sized cities, monorail vehicles are gradually being favored by owners who need small and medium-sized rail transit due to their medium-volume characteristics. However, since the structure of monorail vehicles is different from that of traditional rail vehicles, the relevant production and maintenance equipment needs to be redeveloped according to needs. Transition hooks are indispensable in the production and operation sites of monorails, and transition hooks are required when vehicles need to be moved within the factory. Defects of the prior art: 1: Monorail vehicles are now divided into head vehicles and middle vehicles. The height of the hooks of the two models is different, and the height of the center of the hooks differs by a distance. There is a height difference, and the type of hook head is also different. It is impossible to use a transition hook to be compatible with two models. 2: When towing vehicles in the factory, the tractor can only achieve one-to-one towing. The head vehicle can only be towed with the transition hook of the head vehicle. When towing the middle vehicle, it is necessary to change the transition hook of the middle vehicle to tow the middle vehicle, which requires disassembly of the hook. It is troublesome. 3: Since the transition hook is heavy and needs to be removed and replaced on the track beam, it is very time-consuming and laborious. 4: During production, it may be necessary to tow the middle car after towing the first car. There is only one tractor, so the transition coupler needs to be replaced constantly, which seriously affects production efficiency.

[0003] In the prior art, there is a technology named "Railway Transit Vehicle and Monorail Transit System" and with a publication (announcement) number of "CN112849196A", which relates to a rail transit vehicle and a monorail transit system. The rail transit vehicle includes a vehicle body and a buffer coupler, and two adjacent vehicle bodies are connected by a buffer coupler. The buffer coupler includes a first connector, a second connector, a connecting pin and an electromagnetic device. One of the two adjacent vehicle bodies is provided with a first connector, and the other is provided with a second connector. The connecting pin is inserted through the first connector and the second connector to connect the two adjacent vehicle bodies. The electromagnetic device can pull out the connecting pin when powered on, so that the first connector and the second connector are separated. When it is necessary to connect the two adjacent vehicle bodies, it is only necessary to insert the connecting pin through the first connector and the second connector; when it is necessary to separate the two vehicle bodies, it is only necessary to power on the electromagnetic device and pull out the connecting pin from the first connector and the second connector. Therefore, flexible assembly and disassembly of vehicles can be achieved, and rescue can be carried out quickly when the vehicle fails. However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in view of the shortcomings of the prior art, a monorail vehicle transition coupler structure with a simple structure is provided, which can be used to tow both the head car and the intermediate car, and can tow two types of intermediate cars without disassembling the coupler, thereby improving work efficiency, and does not require frequent adjustments in the later stage after installation and debugging, and is easy to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: The present invention discloses a transitional coupler structure for a monorail vehicle.

[0009] The connecting piece plate body and the connecting pipe piece are also connected via a reinforcing plate.

[0010] The other end of the connecting pipe is provided with a connecting pipe connecting groove, and one end of the vehicle traction rod is provided with a vehicle traction rod connecting clamping strip.

[0011] The connecting groove of the connecting pipe is arranged along a circle of the connecting pipe, and the connecting strip of the vehicle traction rod is arranged along a circle of the vehicle traction rod.

[0012] The monorail vehicle transition coupler structure also includes a connecting snap ring, which includes a first snap ring component and a second snap ring component. The first snap ring component has a first groove and a second groove on its inner wall, and the second snap ring component has a first groove and a second groove on its inner wall. The first snap ring component and the second snap ring component are configured to be connected by a bolt and nut assembly.

[0013] The monorail vehicle transition coupler structure also includes a head hook connector.

[0014] The first side surface and the second side surface are in a vertically arranged structure.

[0015] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows: The monorail vehicle transition coupler structure of the present invention is separately manufactured into a tractor vehicle coupler body, a rotating mounting seat, and an intermediate vehicle traction rod connector.

In this way, the applicable scope of the structure is improved, and there is no need to frequently replace the transition hook for different intermediate vehicle models, which is convenient to use.

[0017] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings: As attached Figure 1 -Attached Figure 5As shown, the present invention is a transitional coupler structure for a monorail vehicle, wherein the rotating mounting seat 2 includes a first side surface 9 and a second side surface 10, the tractor coupler body 1 extends from the opening surface of the rotating mounting seat to the interior of the rotating mounting seat 2, the tractor coupler body 1 and the rotating mounting seat 2 are movably connected via a pin 8, the first side surface 9 or the second side surface 10 is connected to the intermediate vehicle traction rod connector 3, the intermediate vehicle traction rod connector 3 includes a connector plate body 11 and a connecting pipe 12, one end of the connecting pipe 12 is connected to the connector plate body 11, and the horizontal height of the connecting pipe 12 is lower than the horizontal height of the tractor coupler body 1. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When setting up the structure, the tractor vehicle coupler body 1, the rotating mounting seat 2, and the intermediate vehicle traction rod connector 3 are made separately. The rotating mounting seat 2 includes an upper plate surface and a lower plate surface. The two adjacent side surfaces of the rotating mounting seat are open surfaces, and the other two adjacent side surfaces of the rotating mounting seat are a first side surface 9 and a second side surface 10. The first side surface 9 and the second side surface 10 are respectively connected to the upper plate surface and the lower plate surface. In this way, the rotating mounting seat 2 can reliably ensure its own strength. The tractor vehicle coupler body 1 extends to the inside of the rotating mounting seat 2 through the open surface. The two are movably connected by a pin shaft. The tractor vehicle coupler body 1 can swing horizontally within a certain range relative to the rotating mounting seat 2. On the one hand, the shaking and swinging requirements during traction are realized. On the other hand, the switching requirements of the intermediate vehicle traction rod connectors 3 of different models can be realized. The first side surface 9 and the second side surface 10 are respectively connected to an intermediate vehicle traction rod connector 3. The two intermediate vehicle traction rod connectors 3 have different structures and are suitable for different vehicle models. According to the use requirements, when it is necessary to tow a certain type of vehicle, the tractor hook body 1 is connected to the tractor, and the rotating mounting seat 2 is rotated, so that the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is extended to the rear position, at which time the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is located at the side position, and the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is connected to the intermediate vehicle of the corresponding model. When it is necessary to tow another type of vehicle, the tractor hook body 1 is connected to the tractor, and the rotating mounting seat 2 is rotated, and the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is extended to the rear position, at which time the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is located at the side position, and the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is connected to the intermediate vehicle of the corresponding model. Because the heights of the couplers of the tractor (lead vehicle) and the intermediate vehicle are different, when the structure is improved, the coupler body 1 of the tractor is of one height, and one end of the connecting pipe 12 of the intermediate vehicle traction rod connector 3 is connected to the connector plate 11, and the horizontal height of the connecting pipe 12 is lower than the horizontal height of the coupler body 1 of the tractor, thereby effectively adapting to the different heights of the couplers of the tractor and the intermediate vehicle. In this way, the applicable scope of the structure is improved, and there is no need to frequently replace the transition coupler for different intermediate vehicle models, which is convenient to use.The monorail vehicle transition coupler structure described in the present invention has a simple structure, can be used to tow both the head vehicle and the intermediate vehicle, and can tow two types of intermediate vehicles without disassembling the coupler, thereby improving work efficiency. After installation and debugging, frequent adjustments are not required in the later stage, and the use is convenient.

[0018] A plurality of first side positioning screws 13 are arranged on the first side 9, and a first side positioning nut is screwed onto each first side positioning screw 13, and a plurality of second side positioning screws are arranged on the second side 10, and a second side positioning nut 14 is screwed onto each second side positioning screw. The above structure can be used to achieve the connection of the intermediate vehicle traction rod connector 3 corresponding to one model through the plurality of first side positioning screws 13 and the plurality of first side positioning nuts on the first side 9, and can be convenient for disassembly and switching. Similarly, the plurality of second side positioning screws and the plurality of second side positioning nuts 14 on the second side 10 can be used to achieve the connection of the intermediate vehicle traction rod connector 3 corresponding to another model, and can be convenient for disassembly and switching of the traction rod connector.

[0019] The intermediate vehicle traction rod connector 3 includes a first intermediate vehicle traction rod connector 3 and a second intermediate vehicle traction rod connector 3, and the first intermediate vehicle traction rod connector 3 and the second intermediate vehicle traction rod connector 3 respectively include a connector plate 11 and a connecting pipe 12. In the above structure, two types of intermediate vehicle traction rod connectors 3 are provided, and the two types of intermediate vehicle traction rod connectors 3 are different in model and are suitable for intermediate vehicles, which reliably improves the applicable scope of the structure and does not require frequent switching.

[0020] The rotating mounting seat 2 is provided with two mounting seat positioning holes, the tractor vehicle coupler body positioning hole is provided on the tractor vehicle coupler body 1, and the monorail vehicle transition coupler structure further includes a positioning pin 7, and the positioning pin 7 is configured to be able to pass through a mounting seat positioning hole and a tractor vehicle coupler body positioning hole. In the above structure, after the tractor vehicle coupler body 1 rotates 90° relative to the rotating mounting seat 2 so that a corresponding intermediate vehicle traction rod connector 3 is switched to the use position, the positioning pin 7 passes through a mounting seat positioning hole on the rotating mounting seat 2 and a tractor vehicle coupler body positioning hole on the tractor vehicle coupler body 1, thereby realizing the positioning of the rotating mounting seat 2 and a type of intermediate vehicle traction rod connector 3. When the intermediate vehicle traction rod connector 3 needs to be switched, the positioning pin 7 is pulled out, and then after the traction vehicle coupler body 1 is rotated 90° relative to the rotating mounting seat 2 so that another type of intermediate vehicle traction rod connector 3 is switched to the use position, the positioning pin 7 passes through another mounting seat positioning hole on the rotating mounting seat 2 and the traction vehicle coupler body positioning hole on the traction vehicle coupler body 1 to realize the positioning of the rotating mounting seat 2 and another type of intermediate vehicle traction rod connector 3, and the switching is convenient, reliable and fast. The structural improvement of the present invention only requires the plugging and unplugging of the plug pin and the rotating traction rod connector to switch the intermediate vehicle traction rod connector 3, without the need to disassemble and replace the coupler, thereby reducing the workload and improving the work efficiency.

[0021] The connector plate 11 and the connecting pipe 12 are also connected by a reinforcing plate 15. In the above structure, the reinforcing plate 15 effectively improves the connection strength between the connector plate 11 and the connecting pipe 12.

[0022] A connecting pipe connection slot 16 is provided at the other end of the connecting pipe 12, and a vehicle traction rod connection clip strip 17 is provided at one end of the vehicle traction rod 5. The connecting pipe connection slot 16 is provided along the connecting pipe 12, and the vehicle traction rod connection clip strip 17 is provided along the vehicle traction rod 5. The monorail vehicle transition coupler structure also includes a connecting snap ring 4, which includes a first snap ring component 18 and a second snap ring component 19. The first snap ring component 18 has a first groove and a second groove on its inner wall, and the second snap ring component 19 has a first groove and a second groove on its inner wall. The first snap ring component 18 and the second snap ring component 19 are provided as a structure that can be connected by a bolt and nut component 20. In the above structure, after the connecting snap ring 4 is connected by the bolt and nut assembly, the connecting pipe 12 and the vehicle traction rod 5 can be reliably clamped to achieve a reliable connection.

[0023] The monorail vehicle transition coupler structure further comprises a head hook connector 6 .

[0024] The first side surface 9 and the second side surface 10 are arranged vertically. In the above structure, the rotating mounting seat rotates 90 degrees to switch the first side surface 9 and the second side surface 10.

[0025] In the monorail vehicle transition coupler structure described in the present invention, the tractor vehicle coupler body 1 is made of carbon steel parts sprayed with paint, used to connect with the tractor vehicle, and plays the role of supporting the entire coupler. The tractor vehicle coupler body 1 can swing left and right, so it can be used to connect with vehicles in various line conditions. Rotating mounting seat 2: This component has two mutually perpendicular sides (mounting surfaces), which can be connected with two types of intermediate vehicle traction rod connectors 3 respectively, and can rotate around the pin shaft 8. When rotated into place, the tractor vehicle coupler body 1 and the rotating mounting seat 2 are positioned with the positioning pin 7, so that the corresponding intermediate vehicle traction rod connector 3 can be used. Intermediate vehicle coupler connector 3: This part is specially used to connect with the intermediate vehicle coupler. Since the intermediate vehicle coupler is 281mm lower than the head vehicle, a reinforcing plate structure is used to lower the center of the intermediate vehicle traction rod connector 3 to a height that matches the intermediate vehicle to meet the use requirements. Snap ring 4: This snap ring is used to connect the intermediate vehicle traction rod connector 3 with the intermediate vehicle coupler. Head hook connector 5: This hook head is a standard head car hook head, which is specially used to connect with the head car hook. The model and height size match the head car hook head. When using it, you only need to drive the tractor to hit it at a set speed to complete the connection. The transitional hook of the present invention can be compatible with both the head car hook and the intermediate car hook. Even if the two hooks are of different heights, the influence of the height difference of the hooks can be compensated by the sinking design. At the same time, the rotating mounting seat can be used to connect intermediate cars of different models.

[0026] The monorail vehicle transition coupler structure of the present invention is configured by separately manufacturing a tractor vehicle coupler body 1, a rotating mounting seat 2, and an intermediate vehicle traction rod connector 3. The rotating mounting seat 2 includes an upper plate surface and a lower plate surface. The two adjacent side surfaces of the rotating mounting seat are open surfaces, and the other two adjacent side surfaces of the rotating mounting seat are a first side surface 9 and a second side surface 10. The first side surface 9 and the second side surface 10 are respectively connected to the upper plate surface and the lower plate surface. In this way, the rotating mounting seat 2 can reliably ensure its own strength. The tractor vehicle coupler body 1 extends to the inside of the rotating mounting seat 2 through the open surface. The two are movably connected by a pin. The tractor vehicle coupler body 1 can swing horizontally within a certain range relative to the rotating mounting seat 2. On the one hand, the shaking and swinging requirements during traction are realized. On the other hand, the switching requirements of intermediate vehicle traction rod connectors 3 of different models can be realized. The first side surface 9 and the second side surface 10 are respectively connected to an intermediate vehicle traction rod connector 3. The two intermediate vehicle traction rod connectors 3 have different structures and are suitable for different vehicle models. According to the use requirements, when it is necessary to tow a certain type of vehicle, the tractor hook body 1 is connected to the tractor, and the rotating mounting seat 2 is rotated, so that the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is extended to the rear position, at which time the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is located at the side position, and the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is connected to the intermediate vehicle of the corresponding model. When it is necessary to tow another type of vehicle, the tractor hook body 1 is connected to the tractor, and the rotating mounting seat 2 is rotated, and the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is extended to the rear position, at which time the intermediate vehicle traction rod connecting piece 3 connected to the first side 9 is located at the side position, and the intermediate vehicle traction rod connecting piece 3 connected to the second side 10 is connected to the intermediate vehicle of the corresponding model. Because the heights of the couplers of the tractor (lead vehicle) and the intermediate vehicle are different, when the structure is improved, the coupler body 1 of the tractor is of one height, and one end of the connecting pipe 12 of the intermediate vehicle traction rod connector 3 is connected to the connector plate 11, and the horizontal height of the connecting pipe 12 is lower than the horizontal height of the coupler body 1 of the tractor, thereby effectively adapting to the different heights of the couplers of the tractor and the intermediate vehicle. In this way, the application range of the entire transition coupler structure is improved, and there is no need to frequently replace the transition coupler for different intermediate vehicle models, which is convenient to use.

[0027] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
