Description

Technical Field

[0001] The present invention relates to the technical field of connection structures, and particularly to a mounting bracket for an electric power device at the bottom of a mine-use trackless rubber-tyred vehicle. Background Art

[0002] With the increasingly strict national requirements for environmental protection and safety, as well as the continuous development of mine exploitation technologies and the rapid development of new energy technologies, the electrification of mine-use vehicles has become an inevitable trend in the industry. Due to its high efficiency, flexibility, strong adaptability, driverless and other characteristics, the mine-use trackless rubber-tyred vehicle has been widely used in modern mine transportation. As an important mine transportation equipment, the mine-use trackless rubber-tyred vehicle is mainly used for tasks such as underground personnel transportation, material handling, and equipment transfer. The electric power device adopted by the mine-use trackless rubber-tyred vehicle can not only reduce carbon emissions and environmental pollution in the mine, but also effectively reduce operating noise and improve operation safety.

[0003] The electric power device on the mine-use trackless rubber-tyred vehicle is generally installed at the bottom of the rubber-tyred vehicle through a mounting bracket. In the traditional structure, the mounting bracket is a bracket-like structure with multiple mounting positions, which is fastened by bolts. When disassembling and assembling the mounting bracket and the electric power device, due to the narrow space at the bottom of the rubber-tyred vehicle and the bolts for fastening the mounting bracket generally being installed vertically upward from the plane of the bottom of the rubber-tyred vehicle, the disassembly and assembly work is extremely inconvenient, and it is necessary to hold up the mounting bracket at the bottom of the rubber-tyred vehicle for a long time. Therefore, the difficulty of this operation method is relatively large. And for the operation method of lifting the rubber-tyred vehicle with a lift, it is necessary to uniformly move the rubber-tyred vehicle to the position where the lift is located. Therefore, its use convenience is also relatively poor. Summary of the Invention

[0004] The present invention provides a mounting bracket for an electric power device at the bottom of a mine-use trackless rubber-tyred vehicle, which can effectively solve the problems in the background art.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A mounting bracket for an electric power device at the bottom of a mine-use trackless rubber-tyred vehicle, comprising a base fixed to the bottom of the rubber-tyred vehicle, a plurality of intermediate rails provided on the base, long rails provided on each of the intermediate rails, and a bracket installed on the plurality of long rails; The long rails and the intermediate rails both move in the same horizontal direction, and the long rails and the intermediate rails are detachably arranged, and the bracket is designed to install the electric power device; Wherein, a locking structure for locking the position of the long rails is provided on the base.

Detailed Embodiments

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] As Figures 1 to 2 shown, a mounting bracket for a bottom electric power device of a mine trackless rubber-tyred vehicle according to the present invention includes a base 100 fixed to the bottom of the rubber-tyred vehicle, a plurality of intermediate rails 103 provided on the base 100, long rails 101 provided on each intermediate rail 103, and brackets 102 mounted on the plurality of long rails 101; The long rails 101 and the intermediate rails 103 both move in the same horizontal direction, and the long rails 101 and the intermediate rails 103 are detachably arranged. The brackets 102 are designed to mount the electric power device; Among them, a locking structure for locking the position of the long rails 101 is provided on the base 100; In the present invention, the base 100 is pre-fastened to the bottom of the rubber-tyred vehicle by means of bolts, snap connections, etc. The long rail 101 is connected to the bracket 102, and the electric power device of the rubber-tyred vehicle is installed on the bracket 102. In this way, the disassembly and assembly work of the electric power device only needs to complete the disassembly and assembly work of the long rail 101 and the base 100. The base 100 can be used as a general part to cooperate with any long rail 101 and intermediate rail 103; the intermediate rail 103 mainly serves as an intermediate body to realize the connection work between the long rail 101 and the base 100, and the use of the intermediate rail 103 can increase the moving space of the long rail 101, so as to facilitate the direct removal of the bracket 102 from the bottom of the rubber-tyred vehicle without the need for workers to drill into the bottom of the rubber-tyred vehicle and disassemble the bracket 102. This direct removal method can facilitate the workers to directly disassemble and assemble the long rail 101 and the intermediate rail 103 on the side of the rubber-tyred vehicle, and is also convenient for directly overhauling the electric power device on the long rail 101. During assembly, it is also only necessary to install the long rail 101 on the intermediate rail 103 on the side of the rubber-tyred vehicle, thus facilitating the disassembly and assembly work of the electric power device, simplifying the operation method, reducing the operation difficulty, and this method can directly operate at the parking position of the rubber-tyred vehicle, reducing the requirements for the site; the movement mode of the long rail 101 and the intermediate rail 103 on the water surface can directly horizontally move the bracket 102 at the bottom of the rubber-tyred vehicle and the electric power device thereon, thereby reducing the influence of the narrow space at the bottom of the rubber-tyred vehicle on the disassembly and assembly work, and there is no need to lift the electric power device and the bracket 102 for a long time; the same-direction movement of the long rail 101 and the intermediate rail 103 can regard the long rail 101, the intermediate rail 103 and the base 100 as a telescopic structure, so as to extend the moving range of the bracket 102 and facilitate the movement of the electric power device from the bottom of the rubber-tyred vehicle to outside the rubber-tyred vehicle. The number of sections of this telescopic structure can be determined according to the actual situation, that is, the setting quantity of the intermediate rail 103 along its own moving direction is not limited herein. As long as it can achieve the effects of this case, it is within the protection scope of this case; It should be noted that the intermediate rail 103 is slidably connected to the base 100 and is not detachably arranged. The intermediate rail 103 is slidably connected to the long rail 101 and is detachably arranged, that is, the intermediate rail 103 also serves as a general part to cooperate with the base 100; the setting quantity of the intermediate rail 103 and the long rail 101 can be set to two or more, as long as it can provide sufficient sliding distance and support strength for the bracket 102; when the long rail 101, the intermediate rail 103 and the base 100 are contracted to the shortest state, the bracket 102 and the electric power device move to the bottom of the rubber-tyred vehicle. At this time, the position of the long rail 101 can be locked by a locking structure, so as to fix the position of the electric power device; By adopting a horizontally movable design method, the disassembly, installation and maintenance efficiency of the electric power device at the bottom of the mine trackless rubber-tyred vehicle is significantly optimized. The electric power device can be directly removed from the side of the rubber-tyred vehicle through horizontal movement, without workers having to drill into the narrow bottom space or use a lift. This reduces the operation difficulty and requirements for the site, effectively solves the problems of inconvenient disassembly and installation and high labor intensity in the traditional method, improves work efficiency and reduces costs.

[0022] In some embodiments of the present invention, at least part of the moving space of the intermediate rail 103 is located outside the rubber-tyred vehicle, and at least part of the intermediate rail 103 is located on the base 100; In the present invention, as a connecting member, the movement range of the intermediate rail 103 is not limited to the space at the bottom of the rubber-tyred vehicle, but can extend outside the rubber-tyred vehicle through horizontal sliding. This design enables the electric power device installed on the bracket 102 to be directly removed from the bottom of the rubber-tyred vehicle, so that workers can perform disassembly, installation or maintenance operations in a more spacious external environment without having to enter the narrow space under the vehicle. This method significantly reduces the operation difficulty and improves work efficiency; as an intermediate body, part of the intermediate rail 103 is always fixedly or slidably connected to the base 100 to ensure a stable connection relationship with the base 100. The base 100, as a basic component fixed to the bottom of the rubber-tyred vehicle, provides support and guidance for the intermediate rail 103. At the same time, since the intermediate rail 103 is slidably connected to the base 100, the intermediate rail 103 can move relative to the base 100 within a certain range, thereby realizing the horizontal displacement of the electric power device. This design not only ensures the structural stability but also endows the system with flexibility.

[0023] As Figure 2 shown, in some embodiments of the present invention, a first spring 104 is connected between the intermediate rail 103 and the base 100, and a limiting body 105 for limiting the moving space of the intermediate rail 103 is provided on the base 100; It can be seen that the first spring 104 is mainly provided to apply an elastic pulling force to the intermediate rail 103. When the bracket 102 is disassembled and horizontally moved, the first spring 104 will pull the intermediate rail 103 to move synchronously. When the intermediate rail 103 moves to the position of the stopper 105 and is restricted by the stopper 105, the intermediate rail 103 stops moving. At this time, a part of the intermediate rail 103 is located outside the rubber-tyred vehicle, and the first spring 104 stops deforming, thereby transporting the electric power device and the bracket 102 outside the rubber-tyred vehicle, facilitating direct operation by workers. When the bracket 102 is continuously moved, the long rail 101 will slide on the intermediate rail 103 until they are separated from each other, thus completing the disassembly work. From the above content, it can be seen that the use of the first spring 104 is mainly to prevent the intermediate rail 103 from sliding relative to the long rail 101 and causing the bracket 102 to fall off when the bracket 102 has not yet moved outside the rubber-tyred vehicle. This setting method can ensure that the bracket 102 can be translated to the designated position and realizes the sequential movement mode of the intermediate rail 103 and the long rail 101. The limitation of the intermediate rail 103 by the stopper 105 can ensure that at least a part of the intermediate rail 103 is always located on the base 100. In actual use, at least one-third of the intermediate rail 103 needs to be always located on the base 100 to ensure sufficient strength. The stopper 105 can adopt any structure such as a protrusion, a baffle, etc. that can limit the position of the intermediate rail 103, and they are all within the protection scope of this case.

[0024] As Figures 3 to 4 shown, further, a plurality of support plates 106 are provided at the bottom of the base 100, and each support plate 106 supports each long rail 101. Among them, the support plate 106 is inclined, and a supporting surface 107 for cooperating with the support plate 106 is provided at the bottom of the long rail 101. In a common structure, the pallet 106 is generally horizontally arranged, which can lift the structure above the pallet 106. However, in this case, since the long rail 101 needs to move horizontally, there needs to be a certain gap distance between the pallet 106 and the supporting surface 107. The setting of this gap will cause the pallet 106 to be unable to effectively lift the long rail 101; setting the pallet 106 and the supporting surface 107 obliquely can make the pallet 106 and the supporting surface 107 in a surface contact state when the long rail 101 moves to the bottom of the base 100, that is, the pallet 106 realizes the direct and effective lifting effect on the long rail 101 through the supporting surface 107. And this setting method will not affect the movement of the long rail 101. At the same time, along the length direction of the pallet 106, the pallet 106 and the supporting surface 107 can achieve a long-distance contact effect; by adopting the structural setting of the pallet 106 and the supporting surface 107, when the electric power device is in the working position, a firm connection effect between the bracket 102 and the base 100 can be realized, improving the overall firmness of the equipment and avoiding the phenomenon of looseness when the intermediate rail 103, as an intermediate structure, connects the base 100 and the long rail 101.

[0025] As Figures 3 to 4 shown, optimized from the above implementation, a clamping edge 108 is provided on the pallet 106, and a clamping groove 109 for cooperating with the clamping edge 108 is opened at the bottom of the supporting surface 107; Since the pallet 106 and the supporting surface 107 are inclined, the clamping edge 108 and the clamping groove 109 are both in an inclined state. When the bracket 102 moves to the bottom of the rubber-tyred vehicle, the clamping groove 109 moves to the position of the clamping edge 108, and the clamping edge 108 is clamped into the clamping groove 109. At this time, while the pallet 106 realizes the lifting effect on the long rail 101, the clamping edge 108 and the clamping groove 109 also realize the locking effect on the long rail 101 in the horizontal direction, cooperating with the locking structure, so as to realize the direct fastening connection relationship between the base 100 and the long rail 101, greatly improving the structural strength; at this time, the locking structure realizes the lateral limitation of the long rail 101, the pallet 106 realizes the vertical limitation of the long rail 101, and the clamping edge 108 and the clamping groove 109 realize the longitudinal limitation of the long rail 101.

[0026] Further, the locking structure includes a sealing plate 110 slidably installed on the pallet 106, and the sealing plate 110 is located at the lower end of the pallet 106. The sealing plate 110 is used to block the end opening of the pallet 106, and the sealing plate 110 is connected to the pallet 106 through a second spring 111; Since the support plate 106 is inclined, the lower end of the support plate 106 faces the movable direction of the long rail 101, that is, the long rail 101 can move from this end of the support plate 106 to the support plate 106, and the locking structure completes the blocking of this end of the support plate 106, thereby realizing the locking work of the long rail 101; in the present invention, the sliding direction of the sealing plate 110 is perpendicular to the moving direction of the long rail 101, and the second spring 111 provides an elastic thrust for the sealing plate 110. When the long rail 101 moves toward the support plate 106, the support surface 107 at the bottom of the long rail 101 is inclined, so that the bottom surface of the support surface 107 can generate a thrust on the sealing plate 110, so that the sealing plate 110 automatically avoids the long rail 101, and when the long rail 101 moves onto the support plate 106, the long rail 101 is separated from the sealing plate 110, and the second spring 111 pushes the sealing plate 110 to reset and confine the long rail 101 to the support plate 106, thereby realizing the locking work; It should be noted that when the moving direction of the sealing plate 110 is also horizontal, Figure 3 As shown, the inclination of the support surface 107 cannot generate a lateral thrust on the sealing plate 110, that is, the support surface 107 cannot push the sealing plate 110 to move. At this time, the support surface 107 can be synchronously tilted toward the sealing plate 110 based on its original inclination direction. In this way, the lateral thrust on the sealing plate 110 can be achieved, and in order to reduce friction, a rolling body 112 can be added to the sealing plate 110.

[0027] like Figure 1 As shown, each long rail 101 is provided with a shock absorbing body 200 and a plurality of guide rods 201, the bracket 102 is installed on the long rail 101 through the shock absorbing body 200 and the plurality of guide rods 201, and the guide rods 201 slide vertically on the long rail 101; By providing the shock-absorbing body 200, a buffering effect can be achieved for the bracket 102 and the electric power device thereon, thereby preventing the vibration of the rubber-wheeled vehicle during operation and driving from being transmitted to the electric power device and causing damage to the device, and at the same time preventing the mounting bracket from being loosened and damaged due to vibration; since the bracket 102 and the electric power device thereon will produce relative movement with the base 100 due to the action of the shock-absorbing body 200, it is necessary to achieve a sliding connection relationship between the guide rod 201 and the long rail 101, and the provision of the guide rod 201 can limit the shock-absorbing direction of the bracket 102, thereby preventing the bracket 102 from moving arbitrarily in space.

[0028] like Figures 5 to 6As shown in the figure, optimized based on the above implementation, the shock absorber 200 includes an oil barrel 202 fixed on the long rail 101, a first piston 203 slidably located in the oil barrel 202, and a number of first oil holes 204 opened on the first piston 203. The first oil holes 204 are used to connect the spaces on both sides of the first piston 203. A third spring 205 is connected between one side of the first piston 203 and the oil barrel 202. A connecting rod 206 is provided on the other side of the first piston 203. The end of the connecting rod 206 slides out of the oil barrel 202 and is connected to the bracket 102. In the present invention, the interior of the oil barrel 202 stores oil. When the first piston 203 moves in the oil barrel 202, the oil on the upper and lower sides of the first piston 203 can flow through a number of first oil holes 204. The third spring 205 can provide an elastic pulling force for the first piston 203, so as to provide an elastic pulling force for the bracket 102 through the connecting rod 206. When the rubber-tyred vehicle vibrates, the long rail 101 drives the oil barrel 202 to vibrate. At this time, due to inertia, the first piston 203 will move in the oil barrel 202. The setting of the third spring 205 can provide a buffering force for the first piston 203, so as to provide a buffering effect for the bracket 102. At the same time, when the oil flows through the first oil holes 204, it is restricted by the caliber of the first oil holes 204, so as to utilize the oil and the first oil holes 204 to achieve the damping effect on the first piston 203, so as to avoid the continuous vibration of the bracket 102 and the structures thereon due to the expansion and contraction of the third spring 205.

[0029] In some embodiments of the present invention, the caliber of the first oil holes 204 can be adjusted; this adjustable setting method can adjust the flow rate and flow velocity of the oil when it flows through the first oil holes 204, so as to adjust its damping effect. In the present invention, as Figure 7 shown, a circular chamber can be provided inside the first piston 203, and a rotating body 207 is provided in the circular chamber. The rotating body 207 blocks the first oil holes 204. A number of second oil holes 208 are opened on the rotating body 207. When at least part of the second oil holes 208 coincides with the first oil holes 204, the oil can flow through the first oil holes 204 and the second oil holes 208. In this way, by rotating the rotating body 207, the overlapping area of the second oil holes 208 and the first oil holes 204 can be adjusted, so as to achieve the purpose of adjusting the damping effect; for the convenience of rotating the rotating body 207, an adjusting rod 209 can be inserted through the middle of the connecting rod 206, so that one end of the adjusting rod 209 is connected to the rotating body 207, and the other end of the adjusting rod 209 extends outside the connecting rod 206. In this way, the rotating body 207 can be driven to rotate by rotating the adjusting rod 209. A setscrew 210 can be used to lock between the adjusting rod 209 and the connecting rod 206; it should be noted that the cross-sections of the oil barrel 202 and the first piston 203 can be set in any shape such as square or circular.

[0030] As Figure 6As shown, in some embodiments of the present invention, the shock absorber 200 further includes a secondary barrel 211 mounted on the long rail 101 and a piston three 212 that divides the internal space of the secondary barrel 211. The space on one side of the piston three 212 is used to store high-pressure inert gas, and the space on the other side of the piston three 212 is used to communicate with the inside of the oil barrel 202; By setting high-pressure inert gas on one side of the piston three 212, a certain pressure can be provided to the piston three 212, so as to always provide a certain pressure to the hydraulic oil on the other side of the piston three 212. In this way, the pressure can be transmitted into the oil barrel 202, so that the hydraulic oil in the oil barrel 202 always maintains a certain pressure. The purpose of this is to avoid the formation of bubbles in the oil when the oil pressure is too low, resulting in a decline or even damage to the performance of the damper, that is, to avoid cavitation phenomenon. At the same time, the constant pressure makes the oil flow more smoothly, reduces the resistance inside the damper, and facilitates the provision of a consistent damping force under different working conditions; Since the space occupied by the connecting rod 206 inside the oil barrel 202 decreases when the connecting rod 206 moves towards the outside of the oil barrel 202, more oil is needed to fill the vacated space. The setting of the secondary barrel 211 and the piston three 212 can achieve this purpose.
