The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the present invention discloses a transportation vehicle rescue device, which includes a bracket 100, a traveling mechanism and a jacking mechanism 200. In this embodiment, the type of transport vehicle may be multiple, and it may be AGV, RGV, IGV, etc., and the embodiment of the present invention does not limit the specific type of transport vehicle.

Wherein, the bracket 100 is a main body component of the transportation vehicle rescue device, and provides a supporting and installing foundation for the walking mechanism and the jacking mechanism 200.

The transport vechicle rescue device passes through running gear and removes, particularly, when practical application, can lift up the walking wheel group of transport vechicle through this transport vechicle rescue device, makes the walking wheel group take off from ground, realizes the removal of transport vechicle rescue device through running gear this moment, and then drives the transport vechicle and remove. It should be understood that, in this embodiment, what the transport vechicle rescue device was jacked is the running wheel group that the transport vechicle can not rotate, is usually the drive wheel group of transport vechicle, because from the driven wheel group can continue normal rotation when this transport vechicle rescue device drives the transport vechicle and removes, consequently need not jack it up.

It should be noted that, in this embodiment, the type of the supporting surface may be various, and the supporting surface is usually the ground, and may also be other types such as a work table.

The jacking mechanism 200 is a functional component of the transportation vehicle rescue device, and the travelling wheel set of the transportation vehicle can be jacked up by the jacking mechanism 200 to be separated from the supporting surface. In this embodiment, there is at least one jacking mechanism 200, that is, there may be one or more jacking mechanisms 200. As shown in fig. 2, there are two jacking mechanisms 200, and in this case, when the two jacking mechanisms 200 jack the road wheel set of the transport vehicle, the driving effect is more balanced and the stability is better.

The jacking mechanism 200 includes a jacking member 210, a drive assembly 220, and a stop assembly 230. Generally, the lifting member 210 is detachably connected to the support 100, that is, the lifting member 210 can be installed on the support 100 and detached from the support 100; it should be understood that, since the jacking mechanism 200 needs to be jacked at the traveling wheel set of the transportation vehicle, if the jacking member 210 and the bracket 100 are of an integral structure, the jacking member 210 may interfere with the transportation vehicle when the transportation vehicle rescue apparatus is in use, so that the transportation vehicle rescue apparatus is difficult to place under the transportation vehicle, and in this embodiment, the bracket 100 may be placed under the transportation vehicle first, and then the jacking member 210 is assembled to the bracket 100, and after the rescue operation is completed, the jacking member 210 may be detached from the bracket 100 first, and then the bracket 100 may be removed from the transportation vehicle.

The jack 210 is movable on the support 100, that is, the jack 210 can perform relative movement with respect to the support 100. It should be noted that, the embodiment does not limit the specific connection relationship between the jacking member 210 and the support 100, and in an embodiment, as shown in fig. 2 and 4, the jacking member 210 may be a hollow cylindrical structure, which can be sleeved on a support arm structure described later on the support 100 and can move on the support arm structure; in another embodiment, a guide groove structure may be formed on the bracket 100, and a slider structure adapted to the guide groove structure may be disposed on the jacking member 210, so that the jacking member 210 and the bracket 100 are connected and movably connected through a sliding fit relationship between the slider structure and the guide groove structure.

The driving assembly 220 is connected to the lifting member 210, and the driving assembly 220 can drive the lifting member 210 to move on the support 100 along the first direction, that is, the driving assembly 220 can realize that the lifting member 210 moves relative to the support 100, and the moving direction is the first direction.

In this embodiment, the support 100 is provided with a pushing portion 140, and the pushing portion 140 can be pushed against one side of the traveling wheel set of the transportation vehicle to limit the traveling wheel set. It should be noted that, the first direction is not particularly limited in this embodiment, as long as the jacking piece 210 can be close to the abutting portion 140.

Further, the jacking member 210 includes a pushing portion 211, and when the jacking mechanism 200 is mounted on the bracket 100, the pushing portion 211 is disposed opposite to the pushing portion 140. In a specific working process, when the jacking member 210 moves on the bracket 100 along the first direction, the pushing and supporting portion 211 can move towards the supporting portion 140 along with the jacking member 210, that is, the pushing and supporting portion 211 and the supporting portion 140 are close to each other, and because the travelling wheel set of the transport vehicle is located between the pushing and supporting portion 211 and the supporting portion 140, the pushing and supporting portion 211 can gradually approach and push against the travelling wheel set of the transport vehicle, when the jacking member 210 continues to move along the first direction, the pushing and supporting portion 211 and the supporting portion 140 apply acting force to the travelling wheel set of the transport vehicle, and both acting force can be decomposed into jacking force to the vertical supporting surface of the travelling wheel set of the transport vehicle, and under the action of the jacking forces at both sides, the travelling wheel set of the transport vehicle is jacked to be separated from the supporting surface.

In this embodiment, the stop assembly 230 is connected to the lifting member 210, and the stop assembly 230 is capable of cooperating with the bracket 100 to limit the movement of the lifting member 210 on the bracket 100 along the second direction; wherein the first direction is opposite to the second direction. Specifically, when the driving assembly 220 drives the jacking member 210 to move on the bracket 100 along the first direction, the travelling wheel set of the transport vehicle may be detached from the supporting surface by the jacking force, but when the driving assembly 220 cancels the driving action on the jacking member 210, due to the gravity effect of the travelling wheel set of the transport vehicle, the pushing part 211 and the pushing part 140 have a tendency of being pushed by the travelling wheel set of the transport vehicle to be spread, that is, the jacking member 210 moves on the bracket 100 along the second direction under the driving action, and at this time, the travelling wheel set of the transport vehicle has a tendency of falling to the supporting surface; in this embodiment, after the stopping assembly 230 is engaged with the bracket 100, the stopping assembly 230 is limited by the bracket 100, and then the stopping assembly 230 can limit the jacking piece 210, so that the jacking piece 210 cannot move on the bracket 100 along the second direction, thereby ensuring that the road wheel set of the transportation vehicle is always separated from the supporting surface.

Under the general condition, running gear can be the walking wheel group, and this transport vechicle rescue device accessible walking wheel group rolls on the holding surface and realizes removing, and the walking wheel group of the rescue form of this transport vechicle of course can cooperate with the follow driving wheel of transport vechicle, and so the removal effect is better.

Specifically, the traveling mechanism may include a first traveling wheel group 310 and a second traveling wheel group 320, the first traveling wheel group 310 being disposed on the bracket 100, and the second traveling wheel group 320 being disposed on the climbing mechanism 200. So set up down, this transport vechicle rescue device is more even with the removal stress point distribution of holding surface, and the removal efficiency can be higher, moreover also possess with the holding surface under the circumstances of relative movement ability at climbing mechanism 200, also can avoid climbing mechanism 200 direct and ground contact, and be favorable to climbing mechanism 200 relative movement on support 100.

Further, the end portions of the pushing portion 211 and the pushing portion 140 may be provided with a third traveling wheel set, so that the moving performance of the transportation vehicle rescue device can be further optimized, and in practical application, the pushing portion 211 and the pushing portion 140 are in direct contact with the traveling wheel set of the transportation vehicle, and under the condition that the pushing portion 211 and the pushing portion 140 have moving capability, the overall moving effect of the transportation vehicle rescue device is better.

In order to facilitate the moving operation of the transportation vehicle rescue device, in an alternative scheme, as shown in fig. 1 to 3, the transportation vehicle rescue device may further include a traction part 180, the traction part 180 is disposed on the bracket 100, and the traction part 180 is used for pulling the transportation vehicle rescue device. Particularly, the operator can conveniently pull the transportation vehicle rescue device to move by pulling the traction part 180, so that the operation is more labor-saving undoubtedly, and the efficiency is higher.

Further, the pulling part 180 may be hinged to the stand 100, that is, the pulling part 180 may be relatively rotated with respect to the stand 100, so that the pulling angle of the pulling part 180 may be adjusted to suit different operators and operation modes, and to suit a more labor-saving mode. Of course, the specific shape of the pulling portion 180 is not limited in this embodiment, and it may be formed into an ergonomic shape, for example, a handle is disposed on the pulling portion 180 for the operator to grasp.

As can be seen from the above description, in the rescue device for a transportation vehicle disclosed in the embodiment of the present invention, the driving component 220 can drive the jacking component 210 to move on the bracket 100 along the first direction, at this time, the pushing part 211 moves towards the pushing part 140, and the traveling wheel set of the transportation vehicle can be separated from the supporting surface under the joint jacking action of the pushing part 140 and the pushing part 211; meanwhile, the stopping assembly 230 can limit the jacking member 210 to move on the bracket 100 along a second direction opposite to the first direction, so as to avoid the descending of the travelling wheel set of the transport vehicle, further ensure that the travelling wheel set of the transport vehicle is always separated from the supporting surface, and thus, the transport vehicle can be conveniently moved to complete rescue operation.

Compared with the prior art, the embodiment of the utility model discloses a transport vechicle rescue device can reduce the rescue degree of difficulty of transport vechicle undoubtedly to improve rescue efficiency, simultaneously, this rescue device still possesses advantages such as simple structure, simple operation, stable performance, environmental suitability are strong.

In this embodiment, the driving assembly 220 has various types, for example, the driving assembly 220 may include a linear electrode, the linear electrode directly drives the lifting member 210 to move, and the pushing portion 211 approaches or moves away from the pushing portion 140 along with the lifting member 210; alternatively, the driving assembly 220 may include a rack-and-pinion structure, the lifting member 210 is connected to the rack structure, the rack structure is driven by the gear structure to drive the lifting member 210 to move, and the pushing portion 211 is close to or far from the pushing portion 140 along with the lifting member 210.

In another specific embodiment, as shown in fig. 2 to 4, the rack area 150 extending along the first direction may be disposed on the bracket 100, the driving assembly 220 includes a driving element 221 and a transmission module 222, the driving element 221 has a first end and a second end facing away from each other, the first end of the driving element 221 is embedded in a tooth slot of the rack area 150, and the transmission module 222 is connected to the driving element 221. With this arrangement, the transmission module 222 can apply a force to the driving element 221, and the driving element 221 can generate a relative action with respect to the rack area 150.

Meanwhile, the transmission module 222 drives the first end of the driving element 221 to abut against the tooth slot of the tooth rack area 150 along the second direction, so as to push the lifting element 210 to move along the first direction. It should be understood that, as mentioned above, the driving element 221 can generate an opposing action with the rack area 150 under the driving action of the transmission module 222, and since the lifting member 210 is movably disposed on the bracket 100, when the first end of the driving element 221 abuts against the tooth slot of the rack area 150 along the second direction, and the force is further applied, the rack area 150 (corresponding to the bracket 100) applies a reaction force to the driving element 221, and the lifting member 210 can be driven by the driving element 221 to move on the bracket 100 along the first direction.

Alternatively, the transmission module 222 may drive the first end of the driving element 221 to move in the first direction in the rack area 150. It should be understood that, in combination with the foregoing, the stopping assembly 230 may limit the movement of the lifting member 210 on the bracket 100 along the second direction, so that when the driving element 221 drives the lifting member 210 to move on the bracket 100 along the first direction, the stopping assembly 230 may limit the movement of the lifting member 210; at this time, the transmission module 222 can move on the rack area 150 through the first end of the driving element 221 and move along the first direction, so as to change the position of the first end of the driving element 221 on the rack area 150, and then the transmission module 222 can drive the first end of the driving element 221 to abut against the tooth slot of the rack area 150 along the second direction, so as to push the jacking member 210 to move along the first direction again. In this way, the lifting member 210 is continuously driven to move along the first direction on the bracket 100, so as to drive the pushing portion 211 to approach the pushing portion 140.

In the present embodiment, without limiting the specific type of the driving element 221, the driving element 221 can be generally a first pawl, and the rack section 150 can be a ratchet bar; of course, the driving element 221 may be a driving dog, an eccentric sector wedge, or the like.

Meanwhile, the present embodiment also does not limit the specific type of the transmission module 222, for example, the transmission module 222 may be a crank-link structure, and the crank rotates to drive the link and the driving element 221 to reciprocate, so as to achieve the effect of the present embodiment.

In another specific embodiment, the transmission module 222 may include a first transmission rod 222a and a first elastic element 222b, where the first transmission rod 222a is hinged to the lifting member 210, that is, the first transmission rod 222a may rotate relative to the lifting member 210; the second end of the driving element 221 is hinged to the first driving rod 222a, and the second end of the driving element 221 can move close to or away from the rack area 150 along with the rotation of the first driving rod 222 a; both ends of the first elastic member 222b are connected to the first end of the driving member 221 and the lift 210, respectively.

Specifically, with such an arrangement, when the operator drives the first transmission rod 222a downward, the first transmission rod 222a can drive the second end of the driving element 221 to descend, that is, the second end of the driving element 221 moves close to the rack area 150, so that the projection of the driving element 221 on the rack area 150 is lengthened, at this time, the first end of the driving element 221 gradually abuts against the tooth slot of the rack area 150, and drives the rack area 150, and the rack area 150 exerts a reaction force on the driving element 221, and can drive the jacking member 210 to move on the bracket 100 along the first direction through the driving element 221.

After the lifting member 210 moves on the bracket 100, the first end of the driving element 221 will generate a relative displacement with the lifting member 210 under the aforementioned driving action, and in this process, the first elastic element 222b will be stretched; when the first transmission rod 222a is not driven any more, the stored resilient energy of the first elastic element 222b when being stretched is released and recovered, in this process, the first elastic element 222b can pull the first end of the driving element 221 to move on the rack area 150 and move along the first direction, so that the position of the first end of the driving element 221 on the rack area 150 can be changed, and then the first end of the driving element 221 can be driven by the first transmission rod 222a to abut against the tooth grooves of the rack area 150 along the second direction, so as to push the jacking member 210 to continue to move along the first direction. In this way, the lifting member 210 is continuously driven to move along the first direction on the bracket 100, so as to drive the pushing portion 211 to approach the pushing portion 140.

In order to enable the first driving rod 222a to return to the initial position after the driving element 221 is driven, so as to facilitate the secondary driving, in an alternative scheme, the driving module 222 may further include a reset element 222c for driving the first driving rod 222a to rotate, and the reset element 222c is respectively connected to the first driving rod 222a and the lifting member 210.

It should be understood that when the first driving rod 222a drives the driving element 221, it may deviate from the initial position, and it may be difficult to drive the driving element 221 for a second time; in the present embodiment, due to the existence of the reset element 222c, the reset element 222c will generate a driving action on the first driving rod 222a to drive the first driving rod 222a to return to the initial position, so as to drive the driving element 221 again and further drive it for a second time.

In the present embodiment, the specific type of the reset element 222c is not limited, and as shown in fig. 4, the reset element 222c may be selected as a torsion spring; of course, the reset element 222c may also be a compression spring or other structures, specifically, the compression spring may be disposed between the first transmission rod 222a and the jacking member 210, when the operator drives the first transmission rod 222a downward, the compression spring is in a compressed energy storage state, and then the compression spring may be restored to release energy, that is, the first transmission rod 222a may be driven to return to the initial position.

In this embodiment, the types of the stopping assembly 230 are various, for example, the stopping assembly 230 may include a clamping strip movably connected to the jacking member 210, and after the traveling wheel set of the transportation vehicle is jacked up by the jacking mechanism 200, the clamping strip may be placed into the tooth socket of the rack area 150, so that the jacking member 210 is fixedly matched with the rack area 150 through the clamping strip, so that the jacking member 210 does not generate relative displacement with the rack area 150, that is, the jacking member 210 does not generate relative displacement with the bracket 100, and the traveling wheel set of the transportation vehicle always keeps a jacked state.

In another specific embodiment, the stopping assembly 230 may include a stopping element 231, the stopping element 231 has a first end and a second end facing away from each other, the first end of the stopping element 231 is overlapped on the rack section 150, and the stopping element 231 is hinged to the lifting member 210, and the first end of the stopping element 231 can move in the rack section 150 along with the movement of the lifting member 210 or can be embedded in the tooth socket of the rack section 150. Specifically, since the stopper element 231 is hinged to the lifter 210, when the lifter 210 moves on the bracket 100 in a first direction, the stopper element 231 can rotate relative to the lifter 210, so that the first end of the stopper element 231 can move on the rack region 150 without interfering with the rack region 150; when the driving assembly 220 cancels the driving action on the jacking piece 210, the first end of the stopping element 231 is embedded in the tooth slot of the rack area 150, so that the stopping element 231 and the tooth slot of the rack area 150 form a limit matching relationship, and the stopping element 231 can limit the jacking piece 210, so that the jacking piece 210 cannot move on the bracket 100 along the second direction, and further the travelling wheel set of the transport vehicle is ensured to be always separated from the supporting surface.

In the present embodiment, without limiting the specific type of the stop element 231, the stop element 231 may be a second pawl, in which case the rack section 150 may be a ratchet; of course, the stop element 231 may also be a drive dog, an eccentric sector wedge, or the like.

After the vehicle has been transferred to the destination location, the vehicle needs to be lowered, at which point the retaining element 231 (corresponding to the retaining assembly 230) needs to be moved out of engagement with the rack area 150 (corresponding to the rack 100). In one embodiment, the operator may manually lift the stop element 231.

In another specific embodiment, the stopping assembly 230 may further include a second elastic member 232, and both ends of the second elastic member 232 are connected to the first end of the stopping member 231 and the lifting member 210, respectively.

It should be understood that the first elastic element 222b can play a role of pulling the first end of the driving element 221 to be embedded in the tooth socket of the rack area 150, and correspondingly, the second elastic element 232 can play a role of pulling the first end of the stopping element 231 to be embedded in the tooth socket of the rack area 150, at this time, the stopping element 231 can form a limit matching relationship with the tooth socket of the rack area 150, and the stopping element 231 can play a role of limiting the lifting piece 210, so that the lifting piece 210 cannot move on the bracket 100 in the second direction, thereby ensuring that the road wheel set of the transportation vehicle is always separated from the supporting surface.

Of course, the present embodiment is not limited to the specific types of the first elastic element 222b and the second elastic element 232, which may be extension springs in general, but may be other types such as elastic foam, rubber structures, and the like.

When it is desired to lower the vehicle, the jack 210 is required to move in the second direction, and the restraining action of the stop assembly 230 on the jack 210 can be eliminated, particularly by rotating the stop element 231 so that the first end of the stop element 231 is removed from the gullet of the rack section 150, but rotation of the stop element 231 is not conveniently accomplished due to the structural size limitations of the stop element 231 and the layout limitations of other components.

As shown in fig. 5, a second driving lever 231a may be epitaxially formed at a second end of the stopper element 231 in order to optimize the convenience of using the stopper element 231. In this way, an operator can press the second transmission rod 231a downwards, and based on the lever principle, when the stopping element 231 rotates, the second transmission rod 231a can lift the first end of the stopping element 231, so that the stopping element 231 is disengaged from the rack area 150.

Meanwhile, in order to avoid interference between the second driving rod 231a and the first driving rod 222a when in use, the second driving rod 231a of the present embodiment may be bent to avoid the first driving rod 222 a; similarly, the first driving rod 222a of the present embodiment may also be bent to avoid the second driving rod 231 a.

In conjunction with the foregoing, during lowering of the transporter, it is also necessary to disengage the drive element 221 (corresponding to drive assembly 220) from the rack area 150 (corresponding to rack 100), and in one embodiment, the operator can manually lift the drive element 221.

In another specific embodiment, the jacking member 210 may be provided with a screw transmission member 212, and the second end of the driving member 221 is located on the transmission path of the screw transmission member 212. Specifically, the operator can press the second end of the driving element 221 by rotating the screw driving member 212, and then continue to screw in, so as to drive the second end of the driving element 221 to descend, and since the driving element 221 is hinged to the first transmission rod 222a, the driving element 221 will rotate relative to the first transmission rod 222a, and the first end of the driving element 221 will run out of the tooth slot of the rack area 150, at this time, the driving element 221 and the rack area 150 will be disengaged.

Of course, when the transportation vehicle is rescued by the rescue apparatus at the transportation location, the screw driving member 212 needs to be screwed up to avoid the screw driving member 212 from contacting the driving member 221, so as to prevent interference with the driving member 221. Meanwhile, in the present embodiment, the screw driving member 212 may be selected from a driving bolt, a screw, and the like, and the present embodiment does not limit the type thereof.
