Description

Technical Field

[0001] The present application relates to the technical field of battery loading and unloading, and specifically to a battery loading and unloading device for a new energy transport vehicle. Background Art

[0002] A battery loading and unloading device is a commonly used processing equipment, which facilitates the transfer of batteries onto a transport vehicle, thereby improving work efficiency. When the battery loading and unloading device in the prior art is in use, the top plate is generally moved to the bottom of the battery tray by a driving mechanism, and the top plate is driven by a pneumatic cylinder to lift the tray, thereby resetting it so that the battery tray can be installed on the transport vehicle.

[0003] However, since a counterweight is generally installed inside the loading and unloading device to prevent the transport vehicle from tilting when the battery is loaded and unloaded, and since the weight of the counterweight installed inside is certain, when a heavier battery is installed, it will tilt, which is not conducive to the use of operators. A Chinese patent (Announcement No.: CN 220031791 U) discloses a battery loading and unloading device for a new energy transport vehicle, which allows operators to adjust the weight of the counterweight according to the weight of the battery, so as to avoid tilting during loading and unloading, which brings convenience to operators.

[0004] However, it is still inconvenient for the operator to adjust the weight of the counterweight in the above document. When the battery is loaded and unloaded, the battery is moved out of the inner side of the transport vehicle, which makes it inconvenient for the operator to replace the counterweight from the loading and unloading end of the transport vehicle. Therefore, the operator needs to bend down to move the counterweight out from the inner side of the transport vehicle. Since the counterweight has a certain weight, it is inconvenient for the operator to move it out. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a battery loading and unloading device for a new energy transport vehicle, which has the advantages of easy adjustment and solves the problem of inconvenient adjustment.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a battery loading and unloading device for a new energy transport vehicle, comprising a transport vehicle body, a lifting platform is provided at the bottom of the inner cavity of the transport vehicle body, a lifting assembly for adjusting the height of the lifting platform is provided inside the lifting platform, a placing platform for placing a counterweight is fixed on the top of the lifting platform, and a clamping assembly is provided on the top of the placing platform;

[0007] The lifting assembly includes a screw, two moving blocks, two partitions, a dual-axis motor, a lifting rod fixedly mounted on the lower end of the moving block and hinged, a rotating rod fixedly mounted on the output end of the dual-axis motor, a first gear fixedly mounted on the outer surfaces of the two rotating rods, and two second gears fixedly mounted on the outer surfaces of the screw.

[0008] By adopting the above technical solution, when adjusting the weight of the counterweight block, the operator does not need to bend down to move the counterweight block out of the transport vehicle body, which can effectively improve the convenience of the operator during transportation.

[0009] Furthermore, the lifting platform is in the shape of a rectangle with a hollow inner cavity and a missing lower end, and one end of the two lifting rods away from the shifting block is hingedly connected to the bottom of the inner side of the transport vehicle body.

[0010] By adopting the above technical solution, the lifting rod can be hinged to the bottom of the inner cavity of the transport vehicle body, so that the position height of the lifting platform can be adjusted.

[0011] Furthermore, threaded holes for allowing a screw rod to pass through the inside of the two moving blocks are provided on opposite sides of the two moving blocks, and the two sections of threads on the outer surface of the screw rod turn in opposite directions.

[0012] By adopting the above technical solution, the screw rod can drive the two moving blocks to move relative to or away from each other.

[0013] Furthermore, a circular hole for a screw to pass through is provided on one side opposite to the two partitions, and the two partitions are fixed to the inner cavity of the lifting platform.

[0014] By adopting the above technical solution, the partition plate can isolate the second gear from the shift block, thereby preventing the shift block from affecting the operation of the second gear.

[0015] Furthermore, the clamping assembly includes two clamping plates, a first motor, two tooth plates, a transmission tooth fixedly mounted on the output end of the first motor, two T-shaped support plates fixedly mounted on the opposite sides of the two tooth plates, and a connecting rod fixedly mounted on the top of the two outer T-shaped support plates.

[0016] The above technical solution is adopted to clamp and fix the counterweight block, thereby preventing the counterweight block from falling from the placement table, and preventing the counterweight block from shaking in the inner cavity of the transport vehicle body during transportation.

[0017] Furthermore, both the front and rear walls of the inner cavity of the placement table are provided with sliding grooves for the T-shaped support plate to slide in the inner cavity.

[0018] By adopting the above technical solution, two T-shaped support plates in the same group can support the tooth plate, so that the tooth plate can be stably moved in the inner cavity of the placement table.

[0019] Furthermore, a through hole is provided on the top of the placement platform for the connecting rod to pass through.

[0020] By adopting the above technical solution, the connecting rod can pass through the interior of the placement table.

[0021] Furthermore, the tops of the two connecting rods are respectively fixed to the lower ends of the two clamping plates, and the first motor is fixed to the bottom of the inner cavity of the placement table.

[0022] By adopting the above technical solution, the connecting rod can drive the clamping plate to move on the top of the placement table.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The battery loading and unloading device of the new energy transport vehicle is provided with a lifting assembly. When adjusting the weight of the counterweight block, the operator does not need to bend down to move the counterweight block out of the transport vehicle, which can effectively improve the convenience of the operator during transportation. A clamping assembly is provided so that the counterweight block can be clamped and fixed, which can prevent the counterweight block from falling from the placement table and prevent the counterweight block from shaking in the inner cavity of the transport vehicle during transportation.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] See also Figure 1-2 A battery loading and unloading device for a new energy transport vehicle in this embodiment includes a transport vehicle body 1. A lifting platform 2 is provided at the bottom of the inner cavity of the transport vehicle body 1. A lifting component for adjusting the position height of the lifting platform 2 is provided inside the lifting platform 2. A placing platform 3 for placing a counterweight block is fixed on the top of the lifting platform 2. A clamping component is provided on the top of the placing platform 3.

[0031] See also Figure 1-2 The lifting assembly in this embodiment includes a screw rod 21, two moving blocks 22, two partitions 24, a dual-axis motor 25, a lifting rod 23 fixedly mounted on the lower end of the moving block 22, a rotating rod 26 fixedly mounted on the output end of the dual-axis motor 25, a first gear 27 fixedly mounted on the outer surfaces of the two rotating rods 26, and two second gears 28 fixedly mounted on the outer surface of the screw rod 21.

[0032] Moreover, the dual-axis motor 25 is fixed to the top of the inner cavity of the lifting platform 2, and the other ends of the two rotating rods 26 are rotatably connected to the left and right walls of the inner cavity of the lifting platform 2 through bearings, and the left and right ends of the screw 21 are rotatably connected to the left and right walls of the inner cavity of the lifting platform 2 through bearings, so that the rotating rod 26 and the screw 21 can be firmly rotated in the inner cavity of the lifting platform 2.

[0033] Among them, the lifting platform 2 is a rectangle with a hollow inner cavity and a missing lower end. The two lifting rods 23 are hingedly connected to the bottom of the inner side of the transport vehicle body 1 at one end away from the moving block 22, so that the two lifting rods 23 are gradually erected. The two lifting rods 23 can push the lifting platform 2 to move upward in the inner cavity of the transport vehicle body 1, so that the lifting platform 2 can drive the counterweight block to move out of the transport vehicle body 1, so that the operator does not need to bend down to carry the counterweight block, which can improve the convenience of adjusting the weight of the counterweight block.

[0034] In addition, threaded holes are provided on opposite sides of the two moving blocks 22 for the screw 21 to pass through, so that the screw 21 can drive the two moving blocks 22 to move. The two sections of threads on the outer surface of the screw 21 turn in opposite directions, so that the screw 21 can drive the two moving blocks 22 to move relative to or away from each other.

[0035] At the same time, circular holes for the screw 21 to pass through are opened on the opposite sides of the two partitions 24. The two partitions 24 are fixed to the inner cavity of the lifting platform 2, so that the screw 21 can rotate on the inner side of the partition 24, so that when the two moving blocks 22 move away from each other, they can avoid contact with the second gear 28, thereby preventing the partition 24 from affecting the operation of the second gear 28.

[0036] See also Figure 1 and Figure 3 The clamping assembly in this embodiment includes two clamping plates 36, a first motor 31, two tooth plates 33, a transmission tooth 32 fixedly mounted on the output end of the first motor 31, two T-shaped support plates 34 fixedly mounted on the opposite sides of the two tooth plates 33, and a connecting rod 35 fixedly mounted on the top of the two outer T-shaped support plates 34.

[0037] Secondly, the front and rear walls of the inner cavity of the placement table 3 are both provided with sliding grooves for the T-shaped support plate 34 to slide in its inner cavity. The T-shaped support plate 34 can be moved stably in the inner cavity of the placement table 3 through the sliding grooves, so that two T-shaped support plates 34 in the same group can support the tooth plate 33.

[0038] In addition, a through hole is provided on the top of the placement table 3 for the connecting rod 35 to pass through, so as to facilitate the fixing of the connecting rod 35 and the clamping plate 36 so that the connecting rod 35 can drive the clamping plate 36 to move.

[0039] Furthermore, the tops of the two connecting rods 35 are respectively fixed to the lower ends of the two clamping plates 36 , and the first motor 31 is fixed to the bottom of the inner cavity of the placement table 3 .

[0040] The working principle of the above embodiment is:

[0041] During use, when the operator transports heavier electric vehicles and needs to adjust the weight of the counterweight, the output end of the dual-axis motor 25 drives the two rotating rods 26 to rotate, so that the two rotating rods 26 drive the two first gears 27 to rotate, so that the two first gears 27 can mesh with the two second gears 28, so that the two second gears 28 can drive the screw 21 to rotate, and the screw 21 drives the two moving blocks 22 to move back to each other, so that the moving blocks 22 drive the two lifting rods 23 to gradually form a vertical shape, so that the lifting rods 23 can push the lifting platform 2 to gradually move out of the transport vehicle body 1, so that the configuration block gradually moves out of the transport vehicle body 1, so that when the operator adjusts the weight of the counterweight, the operator does not need to bend down to carry the counterweight out of the transport vehicle body 1, which can effectively improve the convenience of adjustment;

[0042] Secondly, when the weight of the counterweight block needs to be adjusted and the counterweight block is moved out of the transport vehicle body 1 (or after the counterweight block is adjusted, the counterweight block is moved into the transport vehicle body 1), the output end of the first motor 31 drives the transmission gear 32 to rotate, so that the transmission gear 32 engages with the two tooth plates 33, thereby causing the two tooth plates 33 to move relative to each other, and the two tooth plates 33 drive the left and right connecting rods 35 to move relative to each other through the front and rear groups of T-shaped support plates 34, so that the two connecting rods 35 drive the two clamping plates 36 to move relative to each other, and the clamping plates 36 clamp and fix the counterweight block, so that when the lifting platform 2 drives the counterweight block to move through the placing platform 3, the counterweight block can be prevented from falling from the placing platform 3, and the transport vehicle body 1 can prevent the counterweight block from shaking in the inner cavity of the transport vehicle body 1 during transportation.
