Description

Technical Field

[0001] This utility model relates to the field of railway vehicle booster equipment technology, and more specifically to vehicle booster devices. Background Technology

[0002] Currently, there are two most common methods for track switching and moving cars. The first method is manual pushing, which requires at least 7 people each time: 4 people push the car, 1 person directs, 1 person watches, and 1 person provides cover. The second method is to use a combined road and rail car or a booster for traction.

[0003] Using manual carts presents several challenges: Safety: Manual cart pushing is highly dangerous; Manpower: Significant manpower waste, with each car expected to be pushed and pulled an average of 6 times during major overhauls, requiring at least 7 people per push; Efficiency: The process of pushing and pulling each car, including waiting time, is lengthy, with each train requiring 30 cars and 7-8 people per trip, totaling approximately 132 hours of work; Accuracy: Manual cart pushing makes precise positioning impossible, often resulting in misalignment of the vehicles.

[0004] Vehicle boosters are used in rail vehicle shunting operations to move an entire train (or a single car) of subway or urban rail vehicles from one workstation to another. Commercially available boosters typically consist of a traction fixture, a power drive system, a control system, a steering wheel assembly, and a drive wheel assembly. The traction fixture and the booster car body are rigidly connected, a lifting fixture ensures reliable connection, the drive wheel assembly connects to a motor to provide driving force, and the steering wheel assembly consists of casters that control the booster's direction of travel.

[0005] By employing a booster, a speed control device, auxiliary positioning wheels, and a safety alarm, emergency stop and braking functions are added, enabling uniform pushing and pulling with effective braking. Previously, pushing a vehicle required 4-6 people, but with this vehicle push-pull equipment, only 1 person is needed, significantly reducing labor costs. Using the booster also reduces waiting time and slow pushing / pulling caused by speed and positioning issues. Furthermore, it solves the problems of stopping, positioning, and alignment during vehicle pushing and pulling.

[0006] Currently, the traction tool and the booster body are rigidly connected. When the booster turns or its direction of travel deviates, a large mechanical stress will be generated at the connection between the traction tool and the booster. Long-term use will reduce the service life of the equipment.

[0007] For those skilled in the art, improving the service life of boosters is a technical problem that needs to be solved. Utility Model Content

[0008] The core of this utility model is to provide a vehicle booster device in which the traction tooling and the booster body form a flexible connection, which can reduce stress concentration caused by rigid connections and improve service life; moreover, three different couplers can meet more diverse usage requirements, as detailed below:

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the vehicle booster device of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Combination Figure 1 As shown, this utility model provides a vehicle booster device, which includes a booster body 10 and a traction fixture 20. The booster body 10 serves as the main structure of the entire vehicle booster device, and the traction fixture 20 is used to connect the coupler. After the traction fixture 20 is connected to the coupler, the booster body 10 can push or pull the vehicle forward.

[0039] The booster unit 10 includes a housing 110, a drive wheel assembly 120, and a steering wheel assembly 130. The housing 110 houses relevant components such as a controller, motor, and battery pack. The drive wheel assembly 120 and the steering wheel assembly 130 are mounted on the housing 110. Figure 1 As shown, the housing 110 is roughly rectangular, the drive wheel assembly 120 is located at one end of the housing 110, and the steering wheel assembly 130 is located at the other end of the housing 110; there are two drive wheel assemblies 120, located on both sides of the housing 110 respectively, and one steering wheel assembly 130, located at the middle of one end of the housing 110.

[0040] In use, the drive wheel assembly 120 provides driving force to move the housing 110. The drive wheel assembly 120 can be driven by a motor and a reducer or other drive device. The direction of travel of the housing 110 is controlled by the steering wheel assembly 130.

[0041] The box body 110 is equipped with a traction adapter 140, combined with Figure 1 As shown, in this embodiment, the traction adapter 140 is disposed on one end side wall of the housing 110, and the traction adapter 140 and the drive wheel assembly 120 are located at the same end of the housing 1.

[0042] The traction adapter 140 includes a traction base 141 and a traction movable seat 142. The traction base 141 is fixedly mounted to the housing 110 and can be directly or indirectly installed on the housing 110. The traction movable seat 142 is swayably mounted to the traction base 141 and can swing relative to the traction base 141.

[0043] The term "traction fixture 20" is a general term. Specifically, the traction fixture 20 includes fully automatic coupler fixture 210, semi-permanent coupler fixture 220, and process bogie fixture 230. The fully automatic coupler fixture 210 is used to connect the fully automatic coupler on the train, the semi-permanent coupler fixture 220 is used to connect the semi-permanent coupler on the train, and the process bogie fixture 230 is used to connect the process bogie installed on the train during maintenance.

[0044] The three types of fixtures—fully automatic coupler fixture 210, semi-permanent coupler fixture 220, and process bogie fixture 230—have different extension structures. The extension rod of the process bogie fixture 230 is the longest, followed by the extension rod of the semi-permanent coupler fixture 220, and the extension rod of the fully automatic coupler fixture 210 is the shortest.

[0045] Automatic couplers are typically located at the ends of trains and are used for connections between trains or between trains and rescue / shunting equipment. The interface design of automatic couplers is perfectly matched to other automatic couplers, ensuring a fast and reliable connection process without requiring manual access under the car. Semi-permanent couplers (Drawbars) are primarily used for connections between cars within the same train unit. They are designed for long-term fixation and infrequent uncoupling. Semi-permanent coupler connections require manual tightening using shackles and bolts, and electrical and pneumatic connections also require manual intervention. Process bogies are directly connected to the process bogies.

[0046] Fully automatic couplers are installed at both ends of the train, allowing the train to quickly and automatically connect or disconnect when needed (such as for rescue, shunting, or marshalling); semi-permanent couplers are installed at the unit connections inside the train to connect the cars together to form a stable whole, and these couplers will not separate unless an emergency occurs or a major overhaul is carried out.

[0047] During the reversing of the train during frame-building and major overhaul, there are three traction conditions depending on whether the process bogie is used and the configuration of the couplers of each unit of the train when the process bogie is not used. These conditions correspond to the three traction fixtures designed in this utility model. They can meet the needs of traction process bogies and ensure that the operator is at the front of the vehicle in the direction of travel when traction of the subway train. Under the premise of meeting safety requirements, they can effectively reduce the number of lookout personnel.

[0048] The fully automatic coupler fixture 210 and the semi-permanent coupler fixture 220 share the same traction movable seat 142, while the process bogie fixture 230 is installed on a separate traction movable seat 142. The two traction movable seats 142 have different heights, thus corresponding to connection positions at different heights; the traction movable seat 142 shared by the fully automatic coupler fixture 210 and the semi-permanent coupler fixture 220 is located at a higher height than the traction movable seat 142 corresponding to the process bogie fixture 230.

[0049] The fully automatic coupler fixture 210 and the semi-permanent coupler fixture 220 can be optionally detachably and fixedly mounted on one of the traction seats 142, and the process bogie fixture 230 can be detachably and fixedly mounted on the other traction seat 142. All three fixtures—fully automatic coupler fixture 210, semi-permanent coupler fixture 220, and process bogie fixture 230—adopt a detachable connection method. Only one of the three fixtures can be used at any given time, thus meeting various docking requirements and broadening the range of applications.

[0050] Since all three types of tooling need to be installed on the traction movable seat 142 during use, and the traction movable seat 142 can swing relative to the traction base 141, all three coupler toolings can swing relative to the booster body 10. Each coupler tooling forms a flexible connection with the booster body 10, which can effectively absorb the vibration and impact energy caused by uneven track or deviation in traction direction, extend the service life of the equipment, and reduce the failure rate.

[0051] Based on the above scheme, the traction base 141 and the traction movable seat 142 of this utility model swing around a vertical axis, that is, the traction base 141 and the traction movable seat 142 are hinged together, and the traction movable seat 142 swings around the vertical axis, so that the tooling can swing left and right. In addition, the traction base 141 and the traction movable seat 142 can also be connected by a ball joint, and these specific connection methods should be included within the protection scope of this utility model.

[0052] Combination Figure 1As shown, a traction handle 150 is provided on the housing 110, and the traction handle 150 and the steering wheel assembly 130 are located at the same end of the housing 110. Specifically, the bottom end of the traction handle 150 is connected to the mounting bracket of the steering wheel assembly 130. The traction handle 150 is used to control the direction of the steering wheel assembly 130. The operator can change the direction of the steering wheel assembly 130 by rotating the traction handle 150. The upper end of the traction handle 150 is for the operator to grip, allowing the operator to apply control force.

[0053] The traction base 141 is provided with a connecting pin or a connecting pin sleeve, and the traction movable seat 142 is provided with a connecting pin sleeve or a connecting pin. Specifically, when the traction base 141 is provided with a connecting pin, the traction movable seat 142 is provided with a connecting pin sleeve; when the traction base 141 is provided with a connecting pin sleeve, the traction movable seat 142 is provided with a connecting pin.

[0054] The connecting pin is inserted into the connecting pin cylinder. A buffer sleeve is provided in the annular gap between the connecting pin and the connecting pin cylinder. The buffer sleeve can further reduce the connection stiffness between the traction base 141 and the traction movable seat 142, and play a shock absorption role.

[0055] In one specific embodiment, the traction adapter 140 includes a drive mechanism 143, combined with Figure 2 As shown, the drive mechanism 143 includes a fixed part and a movable part. The fixed part of the drive mechanism 143 is installed on the housing 110, and the movable part is connected to the traction base 141. The drive mechanism 143 is used to drive the traction base 141 to rise and fall vertically. The vertical position of the traction base 141 can be changed through the drive mechanism 143, which can more easily match and connect with couplers of different heights.

[0056] The drive mechanism 143 can specifically be a hydraulic cylinder, with the cylinder liner fixed to the housing 110 and the cylinder rod connected to the traction base 141. To maintain stability during the lifting process, vertical guide rails are installed on the side wall of the housing 110 to provide vertical guidance for the traction base 141.

[0057] The traction base 141 includes a first base 1411 and a second base 1412, which are combined Figure 2 As shown, the first base 1411 is installed on the movable part of the drive mechanism 143, and the drive mechanism 143 directly drives the first base 1411 to move up and down.

[0058] The first base 1411 is a vertical rod-shaped structure and can be made of hollow steel tubing. Several vertically arranged connecting holes 1413 are provided on the first base 1411 for connection... Figure 2As shown, a row of connecting holes 1413 is provided vertically on both sides of the first base 1411. The two side walls of the second base 1412 are fitted onto both sides of the first base 1411, and the second base 1412 is also provided with through holes, the number of which is less than the number of connecting holes 1413. When the through holes of the second base 1412 are aligned with several connecting holes 1413, the second base 1412 is fixed to the connecting holes 1413 by bolts. By installing it in different connecting holes 1413, the position of the second base 1412 can be adjusted, so that the second base 1412 is fixedly installed in different positions of the first base 1411.

[0059] Each traction movable seat 142 is mounted on a second base 1412, combined with Figure 2 As shown, two second bases 1412 are installed on a first base 1411, and each second base 1412 corresponds to a traction movable seat 142. The two second bases 1412 are installed at different heights. For different models, the two second bases 1412 are installed at different heights. During normal use, it is not necessary to change the position of the second bases 1412. It is only necessary to adjust them vertically within a certain range through the drive mechanism 143.

[0060] Combination Figure 2 As shown, the traction seat 142 is provided with a first ear plate 1421, which is a flat plate structure and has connecting holes. The fully automatic coupler fixture 210, the semi-permanent coupler fixture 220, and the process bogie fixture 230 are each provided with a second ear plate 240, which is also a flat plate structure and has connecting holes. When the first ear plate 1421 and the second ear plate 240 are in contact, they are fixed together by several bolts. For different operating conditions, one of the three fixtures—the fully automatic coupler fixture 210, the semi-permanent coupler fixture 220, and the process bogie fixture 230—is fixedly installed.

[0061] Based on any of the above-mentioned schemes and their combinations, this utility model provides auxiliary positioning assemblies 30 on both sides of the housing 110. Each auxiliary positioning assembly 30 includes an auxiliary rod 310, a positioning seat 320, a positioning wheel 330, and a spring suspension 340. In use, the auxiliary rod 310 extends horizontally or is slightly inclined. One end of the auxiliary rod 310 is mounted on the housing 110, and the other end is connected to the positioning seat 320 via the spring suspension 340. The positioning wheel 330 is mounted on the positioning seat 320. Specifically, the spring suspension 340 includes a connecting rod and a spring. The upper end of the connecting rod is slidably mounted on the auxiliary rod 310, and the lower end of the connecting rod is fixed to the positioning seat 320. When the positioning wheel 330 is impacted, the spring suspension 340 can be compressed, reducing vibration during the movement of the propulsion body 10. Figure 3As shown, each positioning seat 320 is connected to the auxiliary rod 310 via two spring suspensions 340. By setting the spring suspensions 240, when the device encounters unevenness, it stores impact energy, effectively transmits the force between the positioning wheel 330 and the auxiliary rod 310, mitigates operational impact, and ensures smooth operation.

[0062] Combination Figure 3 , Figure 4 As shown, the outer periphery of the positioning wheel 330 is radially protruding with a travel limit block 331, forming a tread shape similar to that of a rail vehicle wheel. The travel limit block 331 is used for positioning with the track. The travel limit block 331 can contact the side of the track to ensure that the vehicle booster device runs longitudinally along the track.

[0063] The end of the auxiliary rod 310 is hinged to the housing 110. The auxiliary rod 310 can swing up and down relative to the housing 110. When the auxiliary positioning assembly 30 is not needed, the auxiliary rod 310 can be retracted upwards. When it needs to move on the track, the auxiliary rod 310 can be adjusted to a horizontal state. A locking structure is provided between the auxiliary rod 310 and the housing 110 to ensure that the auxiliary rod 310 provides certain support to the housing 110 when it is in a horizontal state.

[0064] Combination Figure 5 As shown, an angle limiting block 111 is provided on the housing 110. Two angle limiting blocks 111 are provided to limit the steering angle range of the steering wheel assembly 130, so that the steering wheel assembly 130 can move within a certain angle range to adjust the direction of travel. For example, the angle range of the steering wheel assembly 130 can be limited to 5°, 10°, 15°, etc.

[0065] Combination Figure 5 As shown, the angle limiting block 111 restricts the traction grip 150, thereby limiting the steering angle of the steering wheel assembly 130, ensuring that the booster does not deviate from its direction during operation.

[0066] This utility model employs various replaceable traction fixtures to meet different working conditions; it replaces rigid connections with flexible connections, effectively absorbing vibration and impact energy generated during operation and extending the service life of the device. An angle limit block 111 is provided to limit the rotation angle of the steering wheel assembly 130; an auxiliary positioning assembly 30 is added to ensure the accuracy of traction guidance.
