Description
Technical Field
[0001] This utility model relates to the field of rail maintenance equipment technology, and in particular to a grinding vehicle that can derail and reset. Background Technology
[0002] The grinding machine is the core equipment for railway line maintenance. It is mainly used to grind and repair the surface and contour of the rails, eliminate defects generated during the use of the rails (such as wear, cracks, and wavy wear), restore the standard cross-sectional shape of the rails, extend the service life of the rails, reduce train running noise, and improve the smoothness of the rails and the safety of train operation.
[0003] When the grinding machine is in operation, under normal conditions, the inner sides of the two rails lock the flanges of the grinding machine's wheels, thus limiting the grinding machine's movement to the left and right. This allows the grinding machine's wheels to travel safely on the rails without derailing. However, due to special reasons such as jumping caused by obstacles on the rails, lateral forces during grinding operations, or uneven heights of the rails, the locking mechanism between the flanges and the inner sides of the rails may fail. The wheels may then climb onto the rails from the flanges and fall off. Therefore, it is necessary to reset the grinding machine to return it to the rails and prevent it from becoming immobile in the event of a derailment, which could lead to line paralysis and serious losses.
[0004] In related technologies, due to the large size and weight of grinding vehicles, after a grinding vehicle derails, the common vehicle rerailing device is a hydraulically driven device that needs to be assembled on-site, which requires many operators, is complex, and takes a long time. Utility Model Content
[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a grinding cart that can be derailed and reset. It can be reset by setting a support translation component on the main body of the grinding cart, and setting two support translation mechanisms on both sides of the main body of the grinding cart. The positioning support parts of the two support translation mechanisms support and position the bottom sides of the grinding cart, and then the first driving member and the second driving member move the grinding cart up, down and sideways.
[0006] The technical solution adopted by this utility model to solve its problem is: A derailable and repositionable grinding vehicle includes, Grinding machine body; The support translation assembly includes two support translation mechanisms, which are spaced apart on both sides of the grinding vehicle body in a first direction. Each support translation mechanism includes a first support base, a first drive member, a second support base, and a second drive member. The first support base is provided with a positioning support part, which is connected to the grinding vehicle body. The first support base and the first drive member are mounted on the second support base. The first support base and the second support base are slidably engaged by a guide structure and can slide along the first direction. The first drive member is used to drive the first support base to slide along the first direction. The second drive member is used to drive the second support base to rise and fall.
[0007] As an optional implementation, the guide structure includes a slide rail and a slide groove, both of which extend along the first direction; the slide rail and the slide groove are slidably engaged.
[0008] As an optional implementation, the slide rail is disposed at the bottom end of the first support base, and the slide groove is disposed at the top end of the second support base.
[0009] As an optional implementation, the outer walls on both sides of the slide rail are provided with a first guide slope, which slopes outward from top to bottom; the inner walls on both sides of the slide groove are provided with a second guide slope, which slopes outward from top to bottom; the first guide slope and the second guide slope slide in cooperation.
[0010] As an optional implementation, the positioning support includes a positioning plate and a support plate, the support plate being fixedly disposed at the top of the first support seat; the positioning plate being disposed on the outside of the support plate and vertically connected; the positioning plate and the support plate forming a positioning recess; the bottom side of the grinding machine body being installed in the positioning recess.
[0011] As an optional implementation, the first support base is provided with a reinforcing rib plate, which is connected to the outside of the positioning plate.
[0012] As an optional implementation, the first driving component includes a first hydraulic cylinder, the cylinder body of the first hydraulic cylinder being connected to the second support base, and the piston rod of the first hydraulic cylinder being connected to the bottom end of the first support base.
[0013] As an optional implementation, a connecting piece is provided at the bottom end of the first support base, and the piston rod of the first oil cylinder is hinged to the connecting piece via a rotating shaft.
[0014] As an optional implementation, the second driving component includes a second hydraulic cylinder, the cylinder body of which is provided with a support base, and the piston rod of the second hydraulic cylinder is connected to the second support base.
[0015] As an optional implementation, the support translation assembly includes at least two sets, which are spaced apart at both ends of the grinding vehicle body in a second direction.
[0016] In summary, this utility model has the following technical effects: A support and translation assembly can be installed on the side of the rail. The two support and translation mechanisms of this assembly are distributed on both sides of the grinding vehicle body. When the grinding vehicle body derails during operation, the second drive component descends to contact the ground on the side of the rail. The second drive component then continues to operate, using the ground as support, and reverses direction to lift the second support seat upwards. The positioning support part of the first support seat can position and abut against the bottom and sides of the grinding vehicle body. Then, the first drive component drives the first support seat to move in the first direction, applying force to the side of the grinding vehicle, causing it to translate laterally. This allows the wheels of the grinding vehicle body to re-engage with the rail, thus resetting the grinding vehicle. After the grinding vehicle resets, the second drive component can move upwards and retract, allowing the grinding vehicle body to continue moving. No other structures are needed during derailment; the vehicle can reset itself automatically, making operation convenient. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0026] See Figures 1-9 This utility model discloses a grinding cart that can be derailed and reset, including a grinding cart body 20 and a support and translation component 1. Specifically, the support and translation component 1 includes two support and translation mechanisms 10, which are distributed at intervals on both sides of the grinding cart body 20 in a first direction.
[0027] The support translation mechanism 10 includes a first support base 11, a first driving member, a second support base 13, and a second driving member 12. The first support base 11 is provided with a positioning support part 111, which is connected to the side of the grinding vehicle body 20. The first support base 11 and the first driving member are mounted on the second support base 13. The first support base 11 and the second support base 13 are slidably engaged by a guide structure, allowing the first support base 11 to slide along a first direction. The first driving member drives the first support base 11 to slide along the first direction; the second driving member 12 drives the second support base 13 to rise and fall.
[0028] Based on the above structure, when using the derailable and repositionable grinding cart of this utility model, the grinding cart body 20 can travel on the rails 30 via its wheels 21 to perform maintenance on the rails 30. Under normal conditions, the inner sides of the two rails 30 lock the wheel flanges of the grinding cart 20, thus limiting the left and right sides of the grinding cart body 20, ensuring that the wheels of the grinding cart body 20 can safely travel on the rails 30 without derailing.
[0029] It should be noted that the first direction in this embodiment is the width direction of the main body 20 of the grinding machine 20, that is, the left and right direction.
[0030] Due to obstacles on the rail 30 causing vibration, lateral force during grinding operations, or uneven height of the rail 30, the locking mechanism between the wheel flange and the inner side of the rail 30 fails. The wheel climbs onto the rail 30 from the wheel flange and falls off. However, because the vehicle speed is extremely low during grinding operations, the wheel 21 is very close to the rail 30 after falling off.
[0031] Specifically, the grinding car body 20 has support translation mechanisms 10 distributed on both sides. When performing the derailment reset action, the second drive component can first descend to the ground side of the rail. After that, the second drive component continues to move, and can use the ground as support to lift the second support seat in the opposite direction, so that the first support seat on the second support seat and the grinding car body 20 connected to the positioning support part of the first support seat rise together.
[0032] When the left wheel 21 disengages from the left rail 30, the first support seat 11 of the left-side support translation mechanism 10 can move to the right under the drive of the first driving member. Simultaneously, the first support seat 11 of the right-side support translation mechanism 10 can also move adaptively to the right in conjunction with the left-side support translation mechanism 10 under the drive of the first driving member. This allows the grinding vehicle body 20 to move as a whole and achieve a smoother reset. Conversely, when the right wheel 21 disengages from the left rail 30, the first support seat 11 of the right-side support translation mechanism 10 can move to the left under the drive of the first driving member. Similarly, the first support seat 11 of the left-side support translation mechanism 10 can also move adaptively to the left in conjunction with the right-side support translation mechanism 10 under the drive of the first driving member. This allows the grinding vehicle body 20 to move as a whole and achieve a smoother reset.
[0033] Therefore, a support translation component 1 can be installed on the side of the rail 30, and the two support translation mechanisms 10 of the support translation component 1 are distributed on both sides of the rail 30. The second drive member 12 drives the second support seat 13 to be lifted upward. The first support seat 11 on the second support seat 13 can move to the bottom end of the grinding car body 20. The positioning support part 111 of the first support seat 11 can position and abut against the bottom end and side of the grinding car body 20. After that, the first drive member drives the first support seat 11 to move in the first direction. The first support seat 11 can then apply force to the side of the grinding car body 20, driving the grinding car body 20 to translate in the left and right directions, so that the wheels 21 of the grinding car body 20 can re-engage with the rail 30, thereby realizing the reset of the grinding car body 20.
[0034] In addition, since the main body 20 of the grinding car is large in size, when the whole body is moved by the support and translation mechanism 10 on both sides, the weight is too large and the translation is not smooth. For example, if the main body 20 of the grinding car moves back and forth along the rail 30 during the left and right process, the left and right translation movement will be blocked. Therefore, the first support seat 11 and the second support seat 13 guide the movement in the first direction through the guide structure, and restrict the movement of the main body 20 of the grinding car in the front and back direction.
[0035] Of course, after the grinding carriage is reset, the second drive component can move upward and retract, at which point the grinding carriage body can continue to travel without interfering with the normal travel of the grinding carriage body 20. Compared to related technologies, which require on-site assembly of hydraulic drive devices to reset the grinding carriage body 20, this application eliminates the need for temporary assembly. The support and translation components are directly mounted on both sides of the grinding carriage body, moving with the movement of the grinding carriage body. In use, the support and translation components are raised and translated to support and translate the grinding carriage. It can be used immediately at the derailment position for derailment reset, making the operation process simpler.
[0036] As an optional implementation, the guiding structure in this embodiment includes a slide rail 115 and a slide groove 131. Both the slide rail 115 and the slide groove 131 extend along a first direction. The slide rail 115 and the slide groove 131 are slidably engaged, so that the first support seat 11 and the second support seat 13 can be guided to move in the first direction through the sliding engagement of the slide rail 115 and the slide groove 131.
[0037] Specifically, in this embodiment, the slide rail 115 can be set at the bottom end of the first support base 11, and the slide groove 131 can be set at the top end of the second support base 13. In this way, when the first support base 11 moves relative to the second support base 13 in the first direction, the slide rail 115 at the bottom end of the first support base 11 can slide with the slide groove 131 of the second support base 13, so that the cooperation between the slide groove 131 and the slide rail 115 restricts the front and back swing of the first support base 11 and the second support base 13.
[0038] As an optional implementation, the outer walls of both sides of the slide rail 115 are provided with first guide slopes 116, which slope outward from top to bottom; the inner walls of both sides of the slide groove 131 are provided with second guide slopes 132, which slope outward from top to bottom; the first guide slopes 116 and the second guide slopes 132 slide in cooperation. In this way, the two first guide slopes 116 of the slide rail 115 and the two second guide slopes 132 of the slide groove 131 can form a "V" structure. Even if there is a small gap, the slopes can limit the wobbling through the "automatic centering effect". When the slide rail 115 tends to shift to the left, the right slope will be squeezed by the slide groove 131, generating a rightward corrective force, and vice versa.
[0039] In addition, the inclined surface of the slide rail 115 fits tightly with the inclined surface of the slide groove 131. When an external force attempts to pull the slide rail 115 upward, the inclined surface will generate a "lateral reaction force" to counteract the pull-out force, thus making the guiding structure of the slide rail 115 and the slide groove 131 more stable.
[0040] As an optional implementation, the positioning support 111 includes a positioning plate 113 and a support plate 112. The support plate 112 is fixedly mounted on the top of the first support base 11, and the positioning plate 113 is disposed on the outside of the support plate 112 and vertically connected. The positioning plate 113 and the support plate 112 form a positioning recess. This allows the support plate 112 to abut against the bottom surface of the grinding carriage body 20, while the positioning plate 113 abuts against the outer side of the grinding carriage body 20. The grinding carriage body 20 can be positioned and assembled by the positioning recess formed by the support plate 112 and the positioning plate 113, reducing the displacement of the grinding carriage body during the lifting and translation process.
[0041] It should be noted that a positioning groove can also be directly set on the first support seat 11, and the bottom wall and side wall of the positioning groove are used to position and assemble the bottom end face and outer side face of the grinding machine body 20, respectively.
[0042] As an optional implementation, since the positioning plate 113 is used to abut against the outer side of the grinding machine body 20 to apply force to the grinding machine body 20, the positioning plate 113 is easily subjected to the reaction force of the grinding machine body 20. Therefore, a reinforcing rib 114 can be provided on the first support seat 11. The reinforcing rib 114 is connected to the outer side of the positioning plate 113. In this way, the reinforcing rib 114 can support the outer side of the positioning plate 113, improve the strength of the positioning plate 113, and prevent the positioning plate 113 from breaking under the reaction force of the grinding machine body 20.
[0043] As an optional implementation, the first driving component in this embodiment includes a first hydraulic cylinder. The cylinder body of the first hydraulic cylinder is connected to the second support base 13, and the piston rod of the first hydraulic cylinder is connected to the bottom end of the first support base 11. The piston rod of the first hydraulic cylinder can extend along a first direction, so that the first support base 11 can be translated by the extension and retraction of the piston rod of the first hydraulic cylinder.
[0044] Specifically, a connecting piece 117 can be provided at the bottom of the first support seat 11. The piston rod of the first oil cylinder is hinged to the connecting piece 117 through a rotating shaft. In this way, the first support seat 11 and the piston rod of the first oil cylinder are hinged. The first support seat 11 can adapt to the piston rod of the first oil cylinder during the translation of the grinding machine body 20 due to external force jumping and other factors, reducing the situation of jamming.
[0045] As an optional implementation, the second driving member 12 includes a second hydraulic cylinder, the cylinder body of which is provided with a support base 141, and the piston rod of the second hydraulic cylinder is connected to the second support base 13.
[0046] When the grinding car body 20 derails, the second hydraulic cylinder is activated during the derailment reset operation. The piston rod of the second hydraulic cylinder extends, and the overall height of the grinding car body remains unchanged. The cylinder body of the second hydraulic cylinder descends during the piston rod extension. After descending to the point where the support base 141 contacts the ground, the piston rod of the second hydraulic cylinder continues to extend, using the support base 141 as support, thus initiating the lifting action on the second support seat 13. Since the support base 141 of the second hydraulic cylinder serves as a support surface, its outer diameter can be larger than the outer diameter of the cylinder body, resulting in a larger support surface and more stable support.
[0047] Of course, after the derailment reset action is completed, the piston rod of the second cylinder retracts, which can drive the cylinder body of the second cylinder and the support base back to their original positions and detach from the ground, so that the main body of the grinding vehicle can start to move normally.
[0048] It should be noted that, since the main body 20 of the grinding vehicle is lifted and then moved horizontally in this embodiment, and the overall weight of the main body 20 of the grinding vehicle is relatively large, the first driving component and the second driving component 12 mentioned above are both selected as hydraulic cylinders, which use oil as the medium for driving operation. Compared with the use of pneumatic cylinders, the load-bearing capacity is better and the thrust stability is better.
[0049] As an optional implementation, the support translation component 1 includes at least two sets, which are distributed at intervals in a second direction. The second direction can also be the length direction of the grinding vehicle body, consistent with the extension direction of the rail. That is, at least two sets of support translation components 1 are distributed at different positions on the rail 30. The two support translation mechanisms 10 of each set of support translation components 1 are respectively located at both ends of the grinding vehicle body 20 to perform support translation operations at different positions in the travel direction of the grinding vehicle body 20, making the process more stable.
[0050] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
