[0032] Embodiment 1

[0033] As Figures 1 to 5 shown, a carbon block lifting device is disclosed. The lifting device includes a vehicle body 1, a lifting beam 2 connected to the vehicle body 1, and at least one clamp 3 connected to the lifting beam 2; the clamp 3 includes two clamping arms 32 and two groups of connecting rods connected to the lifting beam 2; each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31. One end of the first connecting rod 30 is hinged to the lifting beam 2, and the other end is hinged to the second connecting rod 31. The end of the second connecting rod 31 away from the first connecting rod 30 is connected to the clamping arm 32. A clamp bracket 33 is also hingedly connected between the two second connecting rods 31; a locking device 4 for locking the open state of the clamp 3 is further provided on the lifting beam 2.

[0034] In this embodiment, the clamp 3 for clamping the carbon block is arranged on the vehicle body 1, and the mobility of the vehicle body 1 is utilized to drive the movement of the clamp 3, so as to realize the clamping and transfer of carbon blocks in different areas. For the convenience of installing the clamp 3, specifically, the clamp 3 can be installed on the clamp beam 2, and the clamp beam 2 is connected to the vehicle body 1. The clamp 3 specifically includes two clamping arms 32 and two groups of connecting rods connected to the lifting beam 2. The two connecting rod structures are the same. Each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31. One end of the first connecting rod 30 is hinged to the lifting beam 2. Specifically, one end of the first connecting rod 30 can be connected to the lifting beam 2 through a pin shaft. The other end of the first connecting rod 30 is hinged to one end of the second connecting rod 31, and specifically, it can also be connected through a pin shaft. Then, the end of the second connecting rod 31 away from the first connecting rod 30 is connected to the clamping arm 32, and specifically, it can also be connected through a pin shaft. At the same time, the two second connecting rods 31 are respectively hinged to the clamp bracket 33.

[0035] In this embodiment, when the lifting device is in the standby state, that is, when the clamp 3 is in the open state, the distance between the two clamping arms 32 is the largest, and the state of the clamp is locked by the locking device 4. During operation, under the action of the vehicle body 1, the clamp 3 is driven to move above the carbon block, and then the clamp beam 2 is lowered. When the clamping arms 32 are located on both sides of the carbon block, the locking device 4 is opened. At this time, the locking device 4 releases the locking of the clamp, and under the action of gravity, the clamping arms 32 will descend. During the descending process, under the articulated action of the two groups of connecting rods and the clamp bracket 33, the clamping arms 32 will gradually approach and finally adhere to both sides of the carbon block. When the lifting beam 2 is lifted, under the articulated action, the clamping arms 32 will tightly adhere to both sides of the carbon block. Through the frictional force between the clamping arms 32 and the carbon block and the clamping force of the two clamping arms 32 on the carbon block, the clamping of the carbon block is realized. Finally, through the vehicle body 1, the carbon block is transferred to the designated area. The lifting beam 2 is lowered again until the carbon block contacts the ground. When the lifting beam 2 is lowered again, under the articulated action, the clamping arms 32 will move away from each other. Finally, it is locked by the locking device 4, and then the lifting beam 2 is pulled up. At this time, the distance between the clamping arms 32 will not change.

[0036] The carbon block is clamped by the clamp 2, and the vehicle body 1 is used to drive the clamp 2 to move, so as to realize the clamping and transfer operation of the carbon blocks in different areas.

[0037] Embodiment 2

[0038] Disclosed is a carbon block lifting device, which includes a vehicle body 1, a lifting beam 2 connected to the vehicle body 1, and at least one clamp 3 connected to the lifting beam 2; the clamp 3 includes two clamping arms 32 and two groups of connecting rods connected to the lifting beam 2; each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31. One end of the first connecting rod 30 is articulated to the lifting beam 2, and the other end is articulated to the second connecting rod 31. The end of the second connecting rod 31 away from the first connecting rod 30 is connected to the clamping arm 32. A clamp bracket 33 is also articulated between the two second connecting rods 31; a locking device 4 for locking the open state of the clamp 3 is further provided on the lifting beam 2.

[0039] The difference between this embodiment and Embodiment 1 is that: a support frame 5, a lifting arm 6 articulated to the support frame 5, and a first hydraulic cylinder 7 are provided on the vehicle body 1; the output end of the first hydraulic cylinder 7 is connected to the lifting arm 6; the lifting beam 2 is connected to the end of the lifting arm 6 away from the vehicle body 1.

[0040] A support frame 5 is provided on the vehicle body 1. Specifically, the support frame 5 is articulated to the vehicle body 1, and the support frame 5 is articulated to the lifting arm 6. Under the action of the first hydraulic cylinder 7, the lifting arm 6 is pushed to rotate relative to the support frame 5, so as to adjust the angle between the lifting arm 6 and the vehicle body 1, and finally achieve the purpose of adjusting the height of the lifting beam 2.

[0041] In this embodiment, specifically, the lifting arm 6 can also be set as a telescopic lifting arm.

[0042] Specifically, a second hydraulic cylinder 8 is further provided at one end of the telescopic boom away from the vehicle body, and the output end of the second hydraulic cylinder 8 is connected to the spreader beam 2. The second hydraulic cylinder 8 is connected to the spreader beam 2, so that the levelness of the fixture 3 can be adjusted through the second hydraulic cylinder 8.

[0043] Embodiment 3

[0044] Disclose a carbon block spreader, the spreader includes a vehicle body 1, a spreader beam 2 connected to the vehicle body 1, and at least one fixture 3 connected to the spreader beam 2; the fixture 3 includes two clamping arms 32 and two groups of connecting rods connected to the spreader beam 2; each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31, one end of the first connecting rod 30 is hinged to the spreader beam 2, the other end is hinged to the second connecting rod 31, and the end of the second connecting rod 31 away from the first connecting rod 30 is connected to the clamping arm 32. A fixture bracket 33 is also hingedly connected between the two second connecting rods 31; a locking device 4 for locking the open state of the fixture 3 is further provided on the spreader beam 2.

[0045] The difference between this embodiment and Embodiment 1 is that in order to increase the friction between the clamping arm 32 and the carbon block, a clamping plate 34 can be provided on the clamping arm 32. Specifically, the shape of the clamping arm 32 can be set as an "L" shape.

[0046] Embodiment 4

[0047] Disclose a carbon block spreader, the spreader includes a vehicle body 1, a spreader beam 2 connected to the vehicle body 1, and at least one fixture 3 connected to the spreader beam 2; the fixture 3 includes two clamping arms 32 and two groups of connecting rods connected to the spreader beam 2; each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31, one end of the first connecting rod 30 is hinged to the spreader beam 2, the other end is hinged to the second connecting rod 31, and the end of the second connecting rod 31 away from the first connecting rod 30 is connected to the clamping arm 32. A fixture bracket 33 is also hingedly connected between the two second connecting rods 31; a locking device 4 for locking the open state of the fixture 3 is further provided on the spreader beam 2.

[0048] The difference between this embodiment and Embodiment 1 is that the locking device 4 includes a window provided on the spreader beam 2, a long shaft 40 and a motor 41 provided on the spreader beam 2. The output end of the motor 41 is connected to the long shaft 40. The locking device 4 further includes a rotating shaft 42 connected to the long shaft 40 and rotating following the movement of the long shaft 40. One end of the rotating shaft 42 away from the long shaft 40 passes through the window and a limit post 43 is provided at the end of the rotating shaft 42 away from the long shaft 40. Specifically, the limit post 43 can be set as two.

[0049] When 9 fixtures 3 are installed on the spreader beam 2, only one long shaft 40 can be provided, and 9 rotating shafts 42 are respectively provided at positions corresponding to the fixtures 3 on the long shaft 40. The 9 rotating shafts 42 are sequentially connected to the fixture brackets 33 of the 9 fixtures 3.

[0050] Specifically, the long shaft 40 and the rotating shaft 42 can be connected by a connecting plate. Under the driving action of the motor 41, the long shaft 40 moves left and right. During the movement of the long shaft 40, the rotating shaft 42 will be driven to rotate.

[0051] When the fixture 3 is in the standby state, that is, when the fixture 3 is in the open state, the two limit posts 43 on the rotating shaft 42 are just located at the bottom of the fixture bracket 33 at the window opening. At this time, the upper end of the rotating shaft 42 is connected to the sling beam 2, and the lower end of the rotating shaft 42 is connected to the fixture bracket 33, so as to ensure that the distance between the sling beam 2 and the fixture bracket 33 will not become larger. Naturally, the fixture 3 cannot be opened. When it is necessary to start the fixture 3 to clamp the material, the motor 41 is started to drive the long shaft 40 to move, thereby driving the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, the limit posts 43 connected to the rotating shaft 42 will also rotate accordingly. Since the size of the limit posts 43 is smaller than the long side size of the window opening, when rotated by 90°, the limit posts 43 will be located directly below the window opening and will not contact the bottom of the fixture bracket 33. At this time, the limit posts 43 will have no lifting force on the fixture bracket 33, and the fixture bracket 33 will descend under the action of gravity. Under the hinge action, the two clamping arms 32 at both ends will gradually approach and thus closely adhere to both sides of the material, thereby realizing the grasping of the material. Through the locking device 4, the open state of the fixture 3 can be locked, so as to ensure that the fixture 3 is always in the open state before clamping the material, thus ensuring that the fixture 3 can smoothly clamp the material.

[0053] Disclosed is a carbon block sling, which includes a vehicle body 1, a sling beam 2 connected to the vehicle body 1, and at least one fixture 3 connected to the sling beam 2; the fixture 3 includes two clamping arms 32 and two groups of connecting rods connected to the sling beam 2; each group of connecting rods includes a first connecting rod 30 and a second connecting rod 31. One end of the first connecting rod 30 is hinged to the sling beam 2, and the other end is hinged to the second connecting rod 31. The end of the second connecting rod 31 far from the first connecting rod 30 is connected to the clamping arm 32. A fixture bracket 33 is also hingedly connected between the two second connecting rods 31; a locking device 4 for locking the open state of the fixture 3 is further provided on the sling beam 2.

[0054] The difference between this embodiment and the above embodiment is that: in order to improve the transfer efficiency of the carbon blocks, specifically, 9 fixtures 3 can be provided on the fixture beam 2. The 9 fixtures 3 are arranged at equal intervals. By providing 9 fixtures 3, 9 carbon blocks can be transferred at one time.

[0055] Of course, the number of the fixtures 3 is not fixed at 9. By increasing the number of the fixtures 3, the transfer efficiency of the carbon blocks can be improved.

[0056] Furthermore, a counterweight 9 is also provided on the vehicle body 1 to keep the vehicle body 1 balanced.

[0057] Obviously, the above embodiments are merely examples for clearly explaining the technical solutions of the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here.
