Description

Technical Field

[0001] The present invention relates to a transport device, in particular to a transport device for power supply equipment applied in the field of power supply equipment transportation. Background Art

[0002] During the construction of urban rail transit, a large number of power supply equipment need to be transported and installed. At present, the transportation of power supply equipment is usually carried out by manpower in conjunction with ordinary rail vehicles. This method of manpower in conjunction with ordinary rail vehicles requires a large number of sleepers and steel plates to be transported to the site before transportation. When unloading, it is necessary to manually build a bridge device with sleepers and steel plates, and then use a hydraulic trolley and a hand winch to transport the power supply equipment to the designated installation location. During the entire transportation process of the power supply equipment, approximately 10 to 15 people are required to work simultaneously, which makes the transportation of the power supply equipment time-consuming and labor-intensive, and greatly affects the work efficiency of the power supply equipment transportation.

[0003] In order to solve the above problems, the specification of Chinese patent CN209395667U discloses a power supply equipment transportation device, including a transportation mechanism, a lifting assembly installed on the transportation mechanism, a loading platform installed on the transportation mechanism through the lifting assembly, and a bridge assembly. The lifting assembly drives the loading platform to be lifted and lowered, the bridge assembly includes an installation state located in the circumference of the loading platform and matched with the loading platform, and the bridge assembly includes a bridge plate and an adjustable support member installed at the bottom of the bridge plate. The power supply equipment transportation device can achieve that when the power supply equipment transportation device loaded with the power supply equipment is moved into place, only a small number of personnel are needed to easily push the power supply equipment from the loading platform to the designated installation position, making the transportation of the power supply equipment more time-saving and labor-saving, thereby making the work efficiency of the power supply equipment transportation higher.

[0004] The height of the wheels at the lower end of the existing power supply equipment transportation device is basically fixed. Therefore, when encountering a rugged road, the device as a whole will be in an uneven state, causing the power supply equipment loaded thereon to also be tilted and the center of gravity to shift. When tilted to a certain angle, it may also roll over, resulting in poor transportation and damage to the equipment. Although the existing power supply equipment transportation device also has wheels that can adaptively rise and fall within a certain range, it is mainly achieved through an elastic damping structure, which can cope with bumpy road conditions well, but for road conditions with a slope, it still cannot prevent the overall displacement of the power supply equipment transportation device or the displacement of the power supply equipment. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to design a transportation device for power supply equipment that can maintain the overall level of the device on rugged roads (especially on slopes) to cope with complex road conditions, ensure that the power supply equipment does not shift its center of gravity or roll over during transportation, and ensure the safety of the power supply equipment and the transportation device itself.

[0006] In order to solve the above problems, the present invention provides a transport device for power supply equipment, including a transport base, a fence and a limit support plate are installed above the transport base, a roller for driving the transport base to move is installed on the circumference of the lower side of the transport base, and a driving motor for driving the roller to rotate is installed at one end of the transport base; A terrain acquisition unit is installed at the forward direction end of the conveyor base, and the terrain acquisition unit is used to acquire terrain data in the forward direction of the conveyor base and transmit it to the processor, and the processor processes the terrain data and transmits the processed data to the controller in real time; A transmission mechanism connected to the output shaft of the driving motor is installed inside the transporter base, and the transmission mechanism drives the roller to rotate; The transmission mechanism is also provided with an adjustment structure, which is used to adjust the distance between the lower end of the roller and the bottom of the conveyor base, and the adjustment structure is electrically connected to the controller.

[0007] In the above-mentioned transportation device for power supply equipment, a terrain acquisition unit is used to obtain terrain data in the forward direction of the transport base and transmit it to the processor. The terrain data is processed by the processor and the processed data is transmitted to the controller in real time; the controller controls the operation of the adjustment structure according to the terrain data, thereby driving the roller to rise or fall, that is, adjusting the distance between the lower end of the roller and the bottom of the transport base, so that the distances between multiple rollers and the bottom of the transport base are different, to adapt to the rugged driving environment, to ensure that the transport base is always in a horizontal state, thereby ensuring that the power supply equipment it carries is always in a horizontal state during transportation, avoiding the center of gravity shift and tilt of the power supply equipment due to the tilt of the transportation device, thereby avoiding the possibility of tilting or overturning of the power supply equipment during transportation, which is beneficial to ensuring the safety of transportation.

[0008] As a further supplement to the present application, the adjustment structure includes a movable connecting member, a second transmission group and a hydraulic cylinder, the movable connecting member is movably mounted on the transmission mechanism, the second transmission group is mounted in the movable connecting member, and one end of the second transmission group is transmission-connected to the roller through a rotating shaft; The hydraulic cylinder is fixedly embedded in the conveyor base, and the end of the piston rod at the lower end of the hydraulic cylinder is fixed to one side of the movable connecting piece.

[0009] As a further supplement to this application, the transmission mechanism includes: A transmission rod, the transmission rod is drivingly connected to the output shaft of the driving motor; A first transmission group, the first transmission group includes a first bevel gear and a second bevel gear, the first bevel gear is fixedly sleeved on one end of the transmission rod, and the second bevel gear is meshed with the first bevel gear; The square rod has an upper end fixed to the second bevel gear, a movable connecting piece is vertically slidably installed on the lower part of the square rod, and the square rod is connected to the roller transmission through the second transmission group.

[0010] As a further supplement to the present application, the second transmission group includes a third bevel gear and a fourth bevel gear. The third bevel gear is vertically slidably sleeved on the square rod. The fourth bevel gear is meshed with the third bevel gear. The third bevel gear is connected to the roller transmission through rotation.

[0011] As a further supplement to the present application, the movable connecting part includes an installation box, the top wall of the installation box is rotatably connected to the upper end of the third bevel gear, and the side of the fourth bevel gear away from the square rod is rotatably connected to one side of the installation box through a rotating shaft.

[0012] Through the arrangement of the first transmission group, the installation box, the hydraulic cylinder, the square rod and the second transmission group, when it is necessary to adjust the vertical distance between the roller and the conveyor base, the controller controls the piston rod of the hydraulic cylinder to extend, so that the hydraulic cylinder drives the installation box to descend. When the installation box descends, the second transmission group installed in the installation box descends synchronously, that is, the third bevel gear slides vertically downward along the square rod, and the fourth bevel gear descends synchronously with the descent of the installation box. During the descent process, the third bevel gear still rotates with the square rod and rotates through the fourth bevel gear, thereby ensuring that the roller still keeps moving during the adjustment process. Since the third bevel gear rotates and is installed in the installation box at the same time, the rotation of the third bevel gear is not affected by the installation box, thereby achieving the adjustment of the distance between the lower ends of the multiple rollers and the lower end of the conveyor base without affecting the overall advancement of the transportation device for the power supply equipment, thereby ensuring that the transportation device for the power supply equipment is always kept level during transportation even if it encounters a rugged road surface, thereby achieving a smooth transportation effect.

[0013] As a further supplement to the present application, a fixing ear is integrally formed on a side of the mounting box away from the roller, and the lower end of the piston rod of the hydraulic cylinder is fixed to the upper end of the fixing ear.

[0014] As a further supplement to the present application, through holes are provided at both the upper and lower ends of the installation box, the square rod movably passes through the through holes, a limit block is fixed at the lower end of the square rod, and the diameter of the limit block is greater than the length of the square rod and smaller than the inner diameter of the through hole.

[0015] By setting the through hole and the limit block, it is possible to avoid friction with the square rod during the lifting and packing process, thereby preventing the lifting process from being affected. At the same time, after the third bevel gear drops to a certain height, the lower end abuts against the limit block and stops dropping, thereby preventing the third bevel gear from being separated from the square rod. Since the square rod and the third bevel gear rotate synchronously, there is no friction when the third bevel gear abuts against the limit block, thereby avoiding damage to the third bevel gear. As a further supplement to the present application, a ball is rollingly embedded in the top wall of the installation box, and the lower end of the ball is in rolling contact with the upper end of the third bevel gear.

[0016] To summarize, a terrain acquisition unit is used to acquire terrain data in the forward direction of the conveyor base and transmit it to a processor. After the processor processes the terrain data and transmits the processed data to a controller in real time, the controller controls the operation of the adjustment structure according to the terrain data, thereby driving the roller to rise or fall, that is, adjusting the distance between the lower end of the roller and the bottom of the conveyor base. Specifically, the controller controls the extension of the piston rod of the hydraulic cylinder so that the hydraulic cylinder drives the installation box to descend. When the installation box descends, the second transmission group installed in the installation box descends synchronously, that is, the third bevel gear slides vertically downward along the square rod, and the fourth bevel gear descends synchronously with the descent of the installation box. During the descent, the third bevel gear still rotates with the square rod and rotates through the fourth bevel gear, thereby maintaining the vertical position of the conveyor base. The rollers keep moving during the adjustment process. Since the third bevel gear is rotated and installed in the installation box at the same time, the rotation of the third bevel gear is not affected by the installation box. Therefore, the distance between the lower ends of the multiple rollers and the lower end of the transport base is adjusted without affecting the overall forward movement of the transport device for the power supply equipment. This makes the distances between the multiple rollers and the bottom of the transport base different to adapt to the rugged driving environment, ensure that the transport base is always in a horizontal state, and thus ensure that the power supply equipment it carries is always in a horizontal state during transportation, avoid the power supply equipment from shifting and tilting its center of gravity due to the tilt of the transport device, thereby avoiding the possibility of the power supply equipment tilting or overturning during transportation, which is beneficial to ensure the safety of transportation.

[0019] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0020] The first implementation method: The present invention provides a transport device for power supply equipment, see Figure 1-Figure 3 , Figure 6 , including a conveyor base 1, a fence 2 and a limit support plate 4 are installed above the conveyor base 1, a roller 3 for driving the conveyor base 1 to move is installed on the lower side of the conveyor base 1, and a driving motor 5 for driving the roller 3 to rotate is installed at one end of the conveyor base 1; A terrain acquisition unit 6 is installed at the forward direction end of the transport base 1. The terrain acquisition unit 6 is used to acquire terrain data in the forward direction of the transport base 1 and transmit it to the processor. The processor processes the terrain data and transmits the processed data to the controller in real time. A transmission mechanism connected to the output shaft of the driving motor 5 is installed inside the transport base 1, and the transmission mechanism drives the roller 3 to rotate; The transmission mechanism is also provided with an adjustment structure, which is used to adjust the distance between the lower end of the roller 3 and the bottom of the conveyor base 1, and the adjustment structure is electrically connected to the controller.

[0021] Based on the above structure, a terrain acquisition unit 6 is used to acquire terrain data in the forward direction of the transport base 1 and transmit it to the processor. After the processor processes the terrain data, the processed data is transmitted to the controller in real time; the controller controls the operation of the adjustment structure according to the terrain data, thereby driving the roller 3 to rise or fall, that is, adjusting the distance between the lower end of the roller 3 and the bottom of the transport base 1, so that the distances between multiple rollers 3 and the bottom of the transport base 1 are different, to adapt to the rugged driving environment, to ensure that the transport base 1 is always in a horizontal state, thereby ensuring that the power supply equipment it carries is always in a horizontal state during transportation, avoiding the center of gravity shift and tilt of the power supply equipment due to the tilt of the transportation device, thereby avoiding the possibility of tilting or overturning of the power supply equipment during transportation, which is beneficial to ensuring the safety of transportation.

[0022] It should be noted that the terrain acquisition unit 6 used in the present application can adopt a device for collecting terrain information that is commonly used in the prior art and applicable to the present embodiment, such as a laser measuring instrument, a terrain detector, etc., and the processor and controller also adopt a processor and controller that is commonly used in the prior art and applicable to the present embodiment, so as to realize terrain information processing and be able to control and adjust the distance between the roller 3 and the bottom of the conveyor base 1 according to the obtained terrain data information.

[0023] Figure 3-Figure 4 The adjustment structure includes a movable connecting member, a second transmission group 12 and a hydraulic cylinder 9. The movable connecting member is movably mounted on the transmission mechanism, the second transmission group 12 is mounted in the movable connecting member, and one end of the second transmission group 12 is transmission-connected to the roller 3 through a rotating shaft; The hydraulic cylinder 9 is fixedly embedded in the conveyor base 1, and the piston rod end at the lower end of the hydraulic cylinder 9 is fixed to one side of the movable connecting piece.

[0024] Figure 3-Figure 4 The transmission mechanism is shown to include a transmission rod 10, a first transmission group 7 and a square rod 11, and the transmission rod 10 is transmission-connected to the output shaft of the driving motor 5; The first transmission group 7 includes a first bevel gear 701 and a second bevel gear 702. The first bevel gear 701 is fixedly sleeved on one end of the transmission rod 10, and the second bevel gear 702 is meshed with the first bevel gear 701. The upper end of the square rod 11 is fixed to the second bevel gear 702 , and the movable connecting piece is vertically slidably installed on the lower part of the square rod 11 . The square rod 11 is transmission-connected to the roller 3 through the second transmission group 12 .

[0025] Figure 4It is shown that the second transmission group 12 includes a third bevel gear 1201 and a fourth bevel gear 1202. The third bevel gear 1201 is vertically slidably sleeved on the square rod 11. The fourth bevel gear 1202 is meshed with the third bevel gear 1201. The third bevel gear 1201 is transmission-connected to the roller 3 by rotation.

[0026] Figure 4 The movable connecting part is shown to include an installation box 8, the inner top wall of the installation box 8 is rotatably connected to the upper end of the third bevel gear 1201 through a bearing, and the bearing does not contact the square rod 11, and the side of the fourth bevel gear 1202 away from the square rod 11 is rotatably connected to one side of the installation box 8 through a rotating shaft.

[0027] Through the arrangement of the first transmission group 7, the installation box 8, the hydraulic cylinder 9, the square rod 11 and the second transmission group 12, when it is necessary to adjust the vertical distance between the roller 3 and the conveyor base 1, the controller controls the piston rod of the hydraulic cylinder 9 to extend, so that the hydraulic cylinder 9 drives the installation box 8 to descend. When the installation box 8 descends, the second transmission group 12 installed in the installation box 8 descends synchronously, that is, the third bevel gear 1201 slides vertically downward along the square rod 11, and the fourth bevel gear 1202 descends synchronously with the installation box 8. During the descent, the third bevel gear 1201 still rotates with the square rod 11 and is driven by the fourth bevel gear 1202. The bevel gear 1202 rotates to ensure that the roller 3 remains in motion during the adjustment process. Since the third bevel gear 1201 is simultaneously rotated and installed in the installation box 8, the rotation of the third bevel gear 1201 is not affected by the installation box 8. This allows the distance between the lower ends of the plurality of rollers 3 (i.e., the ground) and the lower end of the transport base 1 to be adjusted without affecting the overall advancement of the transport device for power supply equipment. This ensures that during the transportation of the transport device for power supply equipment, even if it encounters a rough road surface, the transport base 1 can always be kept level, thereby achieving a smooth transportation effect.

[0028] Figure 4 It is shown that a fixing ear 801 is integrally formed on the side of the installation box 8 away from the roller 3 , and the lower end of the piston rod of the hydraulic cylinder 9 is fixed to the upper end of the fixing ear 801 .

[0029] Figure 4 and Figure 8 It is shown that through holes 802 are opened at the upper and lower ends of the box 8, and the square rod 11 movably passes through the through hole 802. A limit block 1101 is fixed at the lower end of the square rod 11. The diameter of the limit block 1101 is greater than the length of the square rod 11 and smaller than the inner diameter of the through hole 802.

[0030] By setting the through hole 802 and the limit block 1101, it is possible to avoid friction with the square rod 11 during the lifting and lowering of the box 8, thereby affecting the lifting process. At the same time, after the third bevel gear 1201 drops to a certain height, the lower end abuts against the limit block 1101 and then stops falling. At this time, there is a gap between the circumferential side of the limit block 1101 and the end of the fourth bevel gear 1202, thereby avoiding the third bevel gear 1201 from disengaging from the square rod 11. Since the square rod 11 drives the third bevel gear 1201 and the limit block 1101 to rotate synchronously and in the same direction at the same time, the third bevel gear 1201 is relatively still when abutting against the limit block 1101, so that the abutment of the third bevel gear 1201 against the limit block 1101 will not generate friction, thereby avoiding damage to the third bevel gear 1201 after the abutment.

[0031] Figure 5 It is shown that a ball 13 is rollingly embedded in the inner top wall of the installation box 8, and the lower end of the ball 13 is in rolling contact with the upper end of the third bevel gear 1201. Through the provision of the ball 13, the friction between the third bevel gear 1201 and the inner top wall of the installation box 8 can be greatly reduced during the rotation process, thereby significantly extending the service life of the third bevel gear 1201 and the installation box 8, ensuring that the transportation device for the power supply equipment is kept in good condition during long-distance transportation, thereby ensuring the smooth completion of long-distance transportation operations.

[0032] Second implementation method: In other embodiments, the driving motor 5 can drive multiple rollers 3 to rotate simultaneously through a linkage structure, or can drive a certain group (front and rear groups) of rollers 3 to rotate, that is, to realize different driving modes of four-wheel drive or front / rear drive to adapt to different geological transportation requirements, which is more flexible and convenient to use.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
