DETAILED DESCRIPTION

[0047] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] like Figure 1-Figure 12 As shown, a lifting device applied to an aluminum electrolytic carbon block warehouse of the present invention comprises a fixed frame 1 capable of moving in the front-rear direction. In this embodiment, a groove with an opening facing upward is first opened on the ground in the warehouse, and then a slide channel is fixedly installed in the groove. Since a pulley is fixedly provided at the bottom of the fixed frame 1, the pulley can slide along the slide channel, and a fifth driving device is fixedly provided on two of the pulleys.

[0049] In this embodiment, the fifth driving device is a fifth driving self-locking motor. After the fifth driving device is started, it can drive two of the pulleys to move along the slide channel to drive the fixed frame 1 to move in the warehouse, making it convenient to take and place the carbon blocks 4.

[0050] A fixed box 3 is provided on the fixed frame 1. A general driving mechanism for moving the fixed box 3 up, down, left, and right is provided on the fixed frame 1. When the general driving mechanism is started, the fixed box 3 can be driven to move, so that the carbon blocks 4 on the fixed box 3 can be moved.

[0051] Specifically, the overall driving mechanism includes a horizontal driving mechanism 23 and a vertical driving mechanism 24. The horizontal driving mechanism 23 is fixedly mounted on the fixed frame 1. The horizontal driving mechanism 23 can move the fixed box 3 in the left-right direction.

[0052] The vertical driving mechanism 24 is fixedly disposed below the horizontal driving mechanism 23 . The bottom of the vertical driving mechanism 24 is fixedly connected to the fixed box 3 to enable the fixed box 3 to move. The vertical driving mechanism 24 can move the fixed box 3 in the up and down directions.

[0053] In order to facilitate the left-right movement of the fixed box 3 , in this embodiment, the horizontal driving mechanism 23 includes a linear slide rail 2301 and a moving frame 2302 , and the linear slide rail 2301 is arranged on the top of the fixed frame 1 .

[0054] In this embodiment, the linear slide rail 2301 is composed of a slide rail, a slider and balls or rollers, so that the slider can move along the slide rail.

[0055] The mobile frame 2302 is connected to the linear slide rail 2301 in a transmission manner so that the mobile frame 2302 can move left and right. The vertical drive mechanism 24 is installed on the mobile frame 2302. In this embodiment, since the mobile frame 2302 is fixedly connected to the slider, when the slider moves, it can drive the mobile frame 2302 to move. This technology is a prior art and will not be elaborated here. When the mobile frame 2302 moves, it can drive the vertical drive mechanism 24 to move, thereby indirectly driving the fixed box 3 to move left and right.

[0056] In order to facilitate the up and down movement of the fixed box 3, in this embodiment, the vertical driving mechanism 24 includes a plurality of vertically arranged connecting rods 2401 and a vertically arranged telescopic device 2402. In this embodiment, the telescopic device 2402 is an electric telescopic rod. When the movable rod of the electric telescopic rod is extended, it can be extended. This technology is a prior art and will not be elaborated here. The connecting rod 2401 is fixed on the mobile frame 2302. When the mobile frame 2302 moves, it can drive the connecting rod 2401 to move. Since the connecting rod 2401 and the fixed box 3 are connected by the telescopic device 2402, the fixed box 3 will also move with the connecting rod 2401 when the connecting rod 2401 moves.

[0057] The lower end of the connecting rod 2401 is fixedly connected to the fixed rod end of the telescopic device 2402, and the movable rod end of the telescopic device 2402 is fixedly connected to the fixed box 3 to realize the up and down movement of the fixed box 3. After the telescopic device 2402 is driven to start, the telescopic rod end of the telescopic device 2402 can drive the fixed box 3 to move up and down, so that the carbon block 4 can be taken or placed.

[0058] When the fixed box body 3 is lowered to a certain position, in the present embodiment, in order to facilitate placing the carbon blocks 4 on the L-shaped plate 5 for lifting and transportation, two relatively arranged L-shaped plates 5 are provided under the fixed box body 3, and the carbon blocks 4 are placed on the two L-shaped plates 5. When the L-shaped plates 5 move, they can drive the carbon blocks 4 to move, and the carbon blocks 4 can be placed on the L-shaped plates 5 for transportation.

[0059] Specifically, a clamping mechanism 6 is provided in the fixed box body 3 , and the two L-shaped plates 5 are both transmission-connected to the clamping mechanism 6 , so that the two L-shaped plates 5 move in opposite directions to each other, thereby clamping the carbon block 4 .

[0060] In this embodiment, after the clamping mechanism 6 is driven, it can drive the two L-shaped plates 5 to move in opposite directions so as to abut against the side of the carbon block 4 to clamp the carbon block 4 and prevent the carbon block 4 from falling during transportation.

[0061] The clamping mechanism 6 includes a main gear 601 and racks 602 that are distributed on the front and rear sides of the main gear 601 and are arranged opposite to each other. The two racks 602 are meshed with the main gear 601. Since the racks 602 and the main gear 601 are meshed with each other, they can drive the two racks 602 to move in opposite or opposite directions.

[0062] A second driving device 17 is fixedly provided in the fixed box body 3. In the present embodiment, the second driving device 17 is a second driving self-locking motor. After the second driving device 17 is started, it can drive the main gear 601 to rotate. The output end of the second driving device 17 is fixedly connected to the main gear 601, and one end of the rack 602 is fixedly connected to the L-shaped plate 5. A sliding hole for sliding the rack 602 is provided on the fixed box body 3, so that the two racks 602 can move in relative or opposite directions. When the two racks 602 move in relative or opposite directions, they can drive the two L-shaped plates 5 to move in relative or opposite directions, so as to clamp the carbon block 4.

[0063] In order to facilitate the auxiliary support of the carbon block 4 during the clamping process, in the present embodiment, a flippable U-shaped frame 7 is provided on the front side of the fixed box body 3, and the upper and lower sides of the U-shaped frame 7 are respectively connected with connecting plates 9 by hinges. When the U-shaped frame 7 is flipped to the front or rear side of the fixed box body 3, the connecting plate 9 can be interconnected with the fixed box body 3.

[0064] In this embodiment, when the U-shaped frame 7 is turned over to the front side or the rear side of the fixed box body 3 , the connecting plate 9 can be turned over so that the connecting plate 9 and the fixed box body 3 are connected to each other.

[0065] Specifically, threaded grooves 8 are respectively provided on the front and rear sides of the fixed box body 3, and threaded holes corresponding to the threaded grooves 8 are opened on the connecting plate 9, and bolts 22 are inserted in the threaded holes. When the connecting plate 9 is flipped to be parallel to the fixed box body 3, the bolts 22 can be passed through the threaded holes and threadedly connected to the threaded grooves 8, so that the connecting plate 9 and the fixed box body 3 are connected to each other. When the U-shaped frame 7 is flipped to the front or rear side of the fixed box body 3, the bolts 22 are passed through the threaded holes and threadedly connected to the threaded grooves 8 to realize the connection between the U-shaped frame 7 and the fixed box body 3 through the connecting plate 9. Similarly, when the U-shaped frame 7 is flipped to the other side, the other connecting plate 9 can be flipped, so that the L-shaped plate 5 can be in placement grooves in different directions, so that the carbon blocks 4 can be placed from the front or rear side without the need for overall rotation, thereby greatly improving work efficiency.

[0066] A telescopic rod 10 is rotatably provided on one side of the two L-shaped plates 5 facing away from each other. In the present embodiment, the telescopic rod 10 is composed of a plurality of sleeves splined together. When the L-shaped plate 5 moves, the sleeves therein can be driven to extend together. The side of the telescopic rod 10 away from the L-shaped plate 5 is fixedly connected to the U-shaped frame 7, so that the U-shaped frame 7 can rotate around the telescopic rod 10, so that the U-shaped frame 7 can protect the front or rear side of the L-shaped plate 5. Through the arrangement of the telescopic rod 10, the L-shaped plate 5 will not affect the flipping and use of the U-shaped frame 7 during the adjustment process, so as to improve the stability between the L-shaped plate 5 and the U-shaped frame 7.

[0067] In order to facilitate the transportation of the carbon blocks 4 and prevent them from falling and being damaged, in the present embodiment, a storage block 11 that can move up and down is slidably provided on the front side of the U-shaped frame 7, and two groups of telescopic components 12 spaced apart on the left and right are provided inside the storage block 11. A protective cloth 13 is fixed between each telescopic component 12 to protect the fallen carbon blocks 4.

[0068] Two slide rails 14 spaced apart from each other and extending in the up-down direction are fixedly provided on the front side of the U-shaped frame 7 , and both upper and lower ends of the slide rails 14 are closed.

[0069] The storage block 11 is slidably inserted in the slide rail 14 so that the storage block 11 can slide.

[0070] In this embodiment, when the carbon block 4 is suspended, the storage block 11 can slide downward under gravity, and then drive the telescopic component 12 to start, so that the protective cloth 13 is extended so that it can be laid under the L-shaped plate 5 to prevent the carbon block 4 from falling and being damaged.

[0071] Specifically, each telescopic assembly 12 includes a scissors-type telescopic frame 1201 and a first drive device 1202. In the present embodiment, the first drive device 1202 is a first drive self-locking motor. After the first drive device 1202 is started, it can drive the scissors-type telescopic frame 1201 to swing, so that the scissors-type telescopic frame 1201 can be extended or retracted. The first drive device 1202 is disposed in the storage block 11, and the output end of the first drive device 1202 is transmission-connected to the scissors-type telescopic frame 1201 to realize the expansion and contraction of the scissors-type telescopic frame 1201.

[0072] In this embodiment, the output end of the first drive device 1202 is fixedly connected to a lead screw, which is rotatably inserted into the scissors-type telescopic frame 1201. One of the round rods on the scissors-type telescopic frame 1201 is threadedly connected and sleeved on the lead screw. When the first drive device 1202 is started, it can drive the lead screw to rotate, thereby driving one of the round rods on the scissors-type telescopic frame 1201 to move closer to one side, so as to realize the extension and contraction of the scissors-type telescopic frame 1201. This technology is prior art and will not be elaborated here.

[0073] In order to assist in suspending the scissors-type telescopic frame 1201 after extension, in the present embodiment, winding wheels 15 are rotatably provided on both the left and right sides of the storage block 11, and a coil spring 16 is fixed inside the winding wheel 15. The other end of the coil spring 16 is fixed on the upper and lower sides of the slide rail 14. After the traction rope 25 is pulled out, the coil spring 16 will be squeezed to tighten the traction rope 25, so as to achieve the auxiliary suspension of one end of the scissors-type telescopic frame 1201 after extension, so as to improve stability.

[0074] A traction rope 25 is fixed on the winding wheel 15, and the traction rope 25 is hingedly connected to one end of the scissors-type telescopic frame 1201 to achieve auxiliary traction on the side of the scissors-type telescopic frame 1201 away from the storage block 11. When the scissors-type telescopic frame 1201 is extended, the traction rope 25 can be pulled out.

[0075] In this embodiment, in order to facilitate the extrusion of the carbon block 4, a first spring 18 is fixedly provided on the inner wall of the L-shaped plate 5, and a first extrusion plate 19 is fixedly provided at the other end of the first spring 18. The first extrusion plate 19 is pressed against the side of the carbon block 4. Under the action of the first spring 18, the first extrusion plate 19 can be pressed against the side of the carbon block 4 to clamp the carbon block 4 from the left and right directions.

[0076] A second spring 20 is fixed to the bottom of the fixed box 3, and a second extrusion plate 21 is fixed to the other end of the second spring 20. The second extrusion plate 21 is against the top of the carbon block 4. Through the setting of the second spring 20, the top of the carbon block 4 can be squeezed to clamp the carbon block 4 from the top and bottom directions.

[0077] Working principle: When in use, since a pulley is fixedly provided at the bottom of the fixed frame 1, the pulley can slide along the slide groove, and a fifth driving device is fixedly provided on two of the pulleys. After the fifth driving device is started, it can drive two of the pulleys to move along the slide groove, so as to drive the fixed frame 1 to move in the warehouse, so as to facilitate the picking up and placement of the carbon blocks 4.

[0078] Since the movable frame 2302 is fixedly connected to the slider, when the slider moves, it can drive the movable frame 2302 to move. This technology is prior art and will not be elaborated here. When the movable frame 2302 moves, it can drive the vertical driving mechanism 24 to move, thereby indirectly driving the fixed box 3 to move left and right; after the driving telescopic device 2402 is started, the end of the telescopic rod of the telescopic device 2402 can drive the fixed box 3 to move up and down, so that the carbon block 4 can be taken or placed.

[0079] The charcoal block 4 is placed on the L-shaped plate 5, and then the second drive device 17 is started, which can drive the main gear 601 to rotate. When the two racks 602 move in relative or opposite directions, they can drive the two L-shaped plates 5 to move in relative or opposite directions, so as to clamp the charcoal block 4. When the U-shaped frame 7 is flipped to the front or rear side of the fixed box 3, the connecting plate 9 can be flipped up so that the connecting plate 9 and the fixed box 3 are connected to each other, so that the L-shaped plate 5 can be in placement grooves in different directions, so that the charcoal block 4 can be placed from the front or rear side without the need for overall rotation, which greatly improves work efficiency.

[0080] When the carbon block 4 is suspended, the storage block 11 can slide downward under gravity, and then drive the telescopic component 12 to start, so that the protective cloth 13 is extended to be laid under the L-shaped plate 5 to prevent the carbon block 4 from falling and being damaged.

[0081] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is limited by the appended claims rather than the above description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
