Description

Technical Field

[0001] The invention relates to the technical field of mine transportation equipment, in particular to a vehicle-mounted lifting device for an electric locomotive. Background Art

[0002] As the core equipment in the mine rail transportation system, electric locomotives are widely used in the transportation of materials, equipment and construction materials in underground mines. In some special operation scenarios, electric locomotives are also equipped with on-board lifting devices for lifting and carrying large equipment or heavy components in the mine. Due to the small space and limited passages inside the mine, the rails mostly use a light-weight and easy-to-lay steel rail system, and their load-bearing capacity and structural stability are weaker than those of ground rails.

[0003] When an electric locomotive performs a lifting operation, the weight of the vehicle body and the load of the hoisted object will be concentrated on the contact point between the wheel and the rail. Since the contact area between the wheel and the rail is small, the bearing pressure per unit area increases significantly, which can easily cause local structural damage to the track. During long-term operation, indentations, plastic deformation, fatigue cracks may appear on the rail surface, and even cause the sleeper to shift or the foundation to sink, which not only affects the safety of vehicle traffic, but also may prevent the lifting operation from being successfully completed.

[0004] In order to reduce the pressure of the wheels on the track, some existing technologies use auxiliary outriggers or limited support structures, so that when the electric locomotive is lifting, part of the load can be transferred to the support surface outside the track through the outriggers, thereby sharing the force load of the track. However, this type of structure still has many limitations in actual underground applications. Especially in the case of limited space in the underground working environment, the deployment of the auxiliary outriggers is often restricted by surrounding structures, support structures or lifting paths, resulting in interference or insufficient space, which affects the deployment and use of the outriggers, reduces the overall operating efficiency, and even makes the outriggers useless.

[0005] For this purpose, we propose a vehicle-mounted lifting device for an electric locomotive. Summary of the invention

[0006] The purpose of the present invention is to provide a vehicle-mounted lifting device for an electric locomotive to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions: a vehicle-mounted lifting device for an electric locomotive, comprising: A vehicle body, wherein the bottom of the vehicle body is rotatably connected to wheels; Pads, the number of pads corresponds to the number of wheels, the top of the pads is an arc-shaped structure, the bottom is a concave structure, the bottom is used to increase the contact area with the rail, the pad is provided with a plate edge on one side close to the inner side of the rail, and the plate edge is used to cooperate with the inner side of the rail; Folding mechanism, which is arranged on both sides of the vehicle body and is used to store or deploy the backing plate; Transverse movement structure, which is connected between the folding mechanism and the vehicle body and is used to keep the relative position of the backing plate and the folding mechanism unchanged relative to the track during the movement of the vehicle body, so as to realize the relative separation or contact between the wheel and the backing plate.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: a vehicle-mounted lifting device for an electric locomotive, comprising: A vehicle body 10, wherein a wheel 11 is rotatably connected to the bottom of the vehicle body 10; The backing plates 20 are corresponding to the number of wheels 11. The top of the backing plates 20 is an arc-shaped structure and the bottom is a concave structure. The bottom is used to increase the contact area with the rail. The backing plates 20 are provided with a plate edge 21 on one side close to the inner side of the rail. The plate edge 21 is used to engage with the inner side of the rail. A folding mechanism 30, which is disposed on both sides of the vehicle body 10 and is used to store or unfold the pad 20; A transverse movement structure 40, which is connected between the folding mechanism 30 and the vehicle body 10, and is used to keep the relative positions of the pad 20 and the folding mechanism 30 unchanged relative to the track during the movement of the vehicle body 10, thereby achieving relative separation or contact between the wheel 11 and the pad 20; It should be noted that in the scenario where the electric locomotive runs on a straight rail and needs to perform a vehicle-mounted lifting operation, the present invention provides a vehicle-mounted lifting device with a reasonable structure and easy operation. Specifically, when the electric locomotive needs to perform a lifting operation on the track, the operator first unfolds the pad 20 through the folding mechanism 30 arranged on both sides of the vehicle body 10, such as Figure 8As shown in the figure, it is laid flat above the rail. Subsequently, the locomotive is started, and fine-tuning control is carried out in cooperation with the transverse movement structure 40 arranged on the vehicle body 10, so as to realize the relative static state of the folding mechanism 30 and the backing plate 20 during operation, that is, to keep its position relative to the track unchanged, so that after the locomotive travels to the target position, its wheels 11 can press on the backing plate 20. During this process, when the vehicle body 10 and the wheels 11 move forward, the servo motor two 41 drives the lead screw two 42 to rotate, so that the sliding plate 43 drives the entire backing plate 20, the folding mechanism 30 and the compensation component 45 to remain stationary in place relative to the rail. After the wheels 11 are pressed into the backing plate 20, the servo motor two 41 stops working, thus completing the preparation steps before the lifting operation.

[0018] The structure of the backing plate 20 adopted in the present invention also has significant technical advantages. Specifically, the top of the backing plate 20 is designed with an arc structure, which can better fit the curved surface contour at the bottom of the locomotive wheels 11, increase the contact area between the wheels 11 and the backing plate 20, and thus effectively disperse the pressure borne by the wheels 11 per unit area, reducing the risk of damage to the backing plate caused by concentrated loads. At the same time, the bottom of the backing plate 20 adopts a concave structure, which can accurately fit the top contour of the rail, enhance the contact stability and friction between the backing plate 20 and the rail, and improve the overall bearing capacity and structural stability during heavy-duty lifting operations.

[0019] In addition, a plate edge 21 is provided at one end of the backing plate 20 close to the inner side of the rail. The plate edge 21 is used to form a clamping structure with the inner side of the rail, further restricting the lateral displacement of the backing plate 20 during operation, ensuring the stable and reliable position of the backing plate 20, and preventing it from shifting or falling off due to the vibration or eccentric load of the vehicle body 10, thus improving the use safety.

[0020] After the lifting operation is completed, the operator makes the folding mechanism 30 and the backing plate 20 remain relatively static again through the transverse movement structure 40, and controls the locomotive to start slowly, so as to realize the gradual separation of the wheels 11 from the backing plate 20. After the backing plate 20 is completely separated from the wheels 11, the backing plate 20 is stored on the side of the vehicle body 10 through the folding mechanism 30, without interfering with the normal operation and driving track of the locomotive, achieving the convenient operation effect of installing and using as needed and storing as needed.

[0021] In summary, through the optimized design of the structure of the backing plate 20 and the coordinated cooperation of the folding and transverse movement mechanisms, the present invention not only improves the adaptability and stability of the vehicle-mounted lifting device under complex working conditions, but also significantly reduces the risk of structural damage to the rail and the wheels 11 caused by concentrated stress.

[0022] Further as Figure 3 and Figure 4 shown, it is worth specifically explaining that the folding mechanism 30 includes: A housing 31, wherein an extension plate 32 is slidably connected in the housing 31, a fixed shaft is fixedly connected to one side of the pad 20, and the fixed shaft is rotatably connected to the bottom end of the extension plate 32, and a rotation mechanism 33 is provided on the extension plate 32, and the rotation mechanism 33 is used to drive the pad 20 to rotate; A servo motor 34, wherein the servo motor 34 is disposed on the upper side of the housing 31, a screw rod 35 is fixedly connected to the end of the internal rotating shaft of the servo motor 34, a connecting ear 36 is fixedly connected to one side of the extension plate 32, and the connecting ear 36 is threadedly connected to the screw rod 35; It should be noted that, in order to realize the unfolding and storage of the pad 20, the servo motor 34 disposed above the housing 31 plays a key driving role. When the pad 20 needs to be unfolded, the servo motor 34 is started, and its internal shaft rotates, driving the screw 35 connected thereto to rotate synchronously. Since the screw 35 and the connecting ear 36 are in a threaded connection relationship, the rotation of the screw will drive the connecting ear 36 to move axially, thereby pushing the extension plate 32 fixedly connected thereto to slide up and down along the inside of the housing 31.

[0023] At the same time, the rotating mechanism 33 provided on the extension plate 32 starts to work in conjunction. The rotating mechanism 33 is used to drive the pad 20 to rotate and unfold around the fixed axis at one end thereof during the movement of the extension plate 32. Thus, while the extension plate 32 slides downward, the pad 20 synchronously completes the rotation and opening action, and finally unfolds above the track to form a stable supporting structure.

[0024] On the contrary, after the pad 20 is used, it is only necessary to control the servo motor 1 34 to run in the reverse direction, so that the screw rod 1 35 rotates in the reverse direction, thereby driving the connecting ear 36 and the extension plate 32 to move upward. In this process, the rotating mechanism 33 works in coordination, so that the pad 20 rotates in the reverse direction around the fixed axis while being lifted, and is gradually folded and recovered to the side of the vehicle body 10. Through the above structure and control coordination, the entire process of unfolding and folding the pad 20 can be automated, and the operation is convenient and efficient, meeting the requirements for stability and rapid deployment in electric locomotive lifting operations.

[0025] Further as Figure 4 As shown, it is worth to explain in detail that the rotating mechanism 33 includes: The first sprocket 331 is fixedly connected to the fixed shaft. The upper end of the extension plate 32 is rotatably connected to the second sprocket 332. A chain 333 is connected between the first sprocket 331 and the second sprocket 332. A gear assembly 334 is fixedly connected to the chain 333. A rack 335 is provided on the inner wall of the housing 31. The gear assembly 334 includes a plurality of gears meshing with each other. One of the gears is fixedly connected to the second sprocket 332, and the other gear meshes with the rack 335 provided on the inner wall of the housing 31, so as to convert the linear motion of the rack 335 into the rotational motion of the backing plate 20 during the up and down movement of the extension plate 32; It should be noted that through the coordinated cooperation of the first sprocket 331, the second sprocket 332, the chain 333, the gears and the rack 335, the rotation mechanism 33 realizes the control of the synchronous unfolding or folding of the backing plate 20 during the up and down sliding of the extension plate 32. Specifically, when the first servo motor 34 drives the first lead screw 35 to rotate, causing the extension plate 32 to move up and down along the housing 31, the second sprocket 332 rotatably connected to the upper end of the extension plate 32 is linked with the first sprocket 331 through the chain 333. A gear assembly 334 is fixedly installed on the chain 333. The gear assembly 334 includes three gears meshing with each other, which are structurally in sequence: a small gear meshing with the rack 335, a large gear in the middle, and an output gear coaxially connected to the second sprocket 332.

[0026] During the movement of the extension plate 32, the small gear rotates under the linear meshing action of the rack 335, and drives the middle large gear and the output gear to rotate in sequence through gear transmission, finally causing the second sprocket 332 to rotate, and then driving the entire chain 333 system to act. Through this rotation process, the backing plate 20 connected to the fixed shaft is synchronously unfolded or folded. This structure cleverly converts the linear motion of the extension plate 32 into the rotational drive of the second sprocket 332, realizing the smooth unfolding and storage of the backing plate 20 in the limited space track interval.

[0027] Furthermore, as shown in Figure 5 、 Figure 8 、 Figure 9 and Figure 10 , it is worth specifically explaining that the lateral movement structure 40 includes: The second servo motor 41 is fixedly connected to the vehicle body 10. The end of the internal rotating shaft of the second servo motor 41 is fixedly connected to the second lead screw 42. A sliding plate 43 is threadedly connected to the second lead screw 42. A guide rail 44 is fixedly connected to the vehicle body 10. The sliding plate 43 is slidably connected to the guide rail 44. A compensation assembly 45 is provided at the bottom of the sliding plate 43; It should be noted that the rotation of the lead screw two 42 is driven by the end of the rotating shaft inside the servo motor two 41. Driven by the rotation of the lead screw two 42, the sliding plate 43 threadedly connected thereto realizes precise linear movement along the guide rail 44 on the vehicle body 10. The movement of the sliding plate 43 further drives the compensation assembly 45 and the folding mechanism 30 in a linkage manner, so that the backing plate 20 can maintain a state of relative rest with respect to the track position during the overall movement of the battery locomotive. Through this process, when the battery locomotive starts or moves slowly in the working mode, the effective separation between the wheels 11 and the backing plate 20 can be achieved.

[0028] Furthermore, as Figure 4 and Figure 5 shown, it is worth specifically stating that the compensation assembly 45 includes: A connecting rod 451, the connecting rod 451 is fixedly connected to the bottom of the sliding plate 43, one side of the housing 31 is fixedly connected with a circular ring part 452, a spiral spring 453 is arranged inside the circular ring part 452, one side of the spiral spring 453 is fixedly connected with the connecting rod 451, and the other side is fixedly connected with the inner wall of the circular ring part 452; It should be noted that the rotation of the lead screw two 42 is driven by the end of the rotating shaft inside the servo motor two 41. The lead screw two 42 drives the sliding plate 43 to move along the direction of the vehicle body 10, and then cooperates with the compensation assembly 45 and the folding mechanism 30 to make the backing plate 20 stationary relative to the rail, that is, the backing plate 20 remains stationary at the top of the rail, and the vehicle body 10 and the wheels 11 move to the other side, so as to realize the separation of the wheels 11 and the backing plate 20. During this process, the compensation assembly 45 not only plays a role in transmission connection, but also has a certain elastic adjustment ability to adapt to the slight offset of the sliding plate 43 and the backing plate 20 in different position states. In addition, during the process of the wheels 11 pressing on the backing plate 20, since the unfolding of the backing plate 20 will cause the wheels 11 to be slightly lifted upward together with the vehicle body 10, at this time, the spiral spring 453 can provide a certain elastic space to adapt to this vertical displacement change, so as to avoid structural interference or impact due to rigid connection, and further improve the flexible buffering performance and use safety of the whole system during operation.

[0029] Furthermore, as Figure 6 shown, it is worth specifically stating that the connecting rod 451 is fixedly connected with limiting circular plates 454 on both sides of the circular ring part 452; It should be noted that the setting of the limiting circular plate 454 is mainly used to restrict the moving direction of the connecting rod 451 inside the circular ring part 452, so that it always moves along the axial direction perpendicular to the plane of the circular ring part 452, preventing the connecting rod 451 from being deflected or swinging during the elastic expansion and contraction of the spiral spring 453. Through the guiding and limiting functions of the limiting circular plate 454, the guiding stability of the compensation assembly 45 can be improved, ensuring that the connecting rod 451 is always in the correct position during expansion and contraction.

[0030] Furthermore, as Figure 7 shown, it is specifically noted that the bottom of the backing plate 20 is a hollow structure, provided with a replaceable anti-slip insert, and the anti-slip insert increases the friction when contacting the rail to prevent slipping; It should be noted that by embedding the replaceable anti-slip insert, the friction coefficient between the backing plate and the rail is increased, preventing the backing plate from slipping during the hoisting operation of the electric locomotive. The anti-slip insert can be conveniently replaced after long-term use or damage, improving the maintainability and service life of the equipment, and ensuring the stability and safety during the hoisting operation.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and all belong to the scope of protection of the present invention.
