Description

Technical Field

[0001] This invention belongs to the field of clamps, and particularly relates to a multi-functional overhead crane clamping plate device for calcining aluminum. Background Technology

[0002] Currently, in aluminum electrolysis, the prebaked anode electrolytic cells used require anode carbon blocks of a certain size and specification. During the manufacturing process of carbon anode blocks, specifically during the anode roasting step, the anode carbon blocks are typically clamped and hoisted using a multi-functional overhead crane for roasting. This hoisting requires a clamping device for the anode carbon blocks. Existing clamping devices hold the carbon blocks using clamping plates equipped with several gripping pins, which increase the stability of the clamping. However, since different factories and power plants use different specifications of carbon blocks, the thickness of the clamping plates used by the overhead crane must also vary depending on the size of the carbon blocks. Changing to clamping plates of different thicknesses results in cumbersome disassembly and installation operations. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention aims to provide a clamping plate with variable thickness to solve the problems mentioned in the background section. To achieve the above objective, the present invention provides the following technical solution: A multi-functional overhead crane clamping plate device for calcining aluminum, the device comprising: clamping arms, clamping plates, thickened plates, plate surface gripping nails, and a transmission module; The clamping plate is fixedly connected to several clamping arms, and several plate-side gripping nails are installed on the clamping plate; The thickened plate is mounted on the clamping arm via a transmission module, and a number of plate-side gripping nails are installed on the thickened plate. Both the clamping plate and the thickened plate include a clamping end and a supporting end. The supporting end is the end close to the clamping arm, and the clamping end is the end away from the clamping arm. The thickened plate has two rated positions when it moves; when the thickened plate is in one rated position, the supporting end of the thickened plate is in contact with the clamping arm, and the plate surface grappling nail on the thickened plate and the plate surface grappling nail on the clamping plate are located on the same plane; when the thickened plate is in the other rated position, the supporting end of the thickened plate is in contact with the clamping end of the clamping plate. The transmission module is used to move the thickened plate between two rated positions.

[0004] Furthermore, the thickened plate includes a nail-grabbing plate, a vertical plate, a horizontal plate, and a support plate. Two vertical plates and two horizontal plates are fixedly connected to each other to form a thickened frame. The nail-grabbing plate is fixedly connected to the thickened frame. The support plate is fixedly installed inside the thickened frame. One end of the support plate is attached to the nail-grabbing plate, and the other end of the support plate can be attached to the clamping arm.

[0005] Furthermore, the thickened plate is also provided with several reinforcing plates that are perpendicular to the support plate.

[0006] Furthermore, the transmission module includes a connecting rod, a limiting block, a transmission shaft A, and a drive; the output shaft of the drive is connected to two transmission shafts A through a gearbox, the two transmission shafts A rotate in the same direction, and both ends of each transmission shaft A are fixedly connected to a limiting block. A connecting rod is inserted into each limiting block, the connecting rod can rotate with the transmission shaft A, each connecting rod is parallel to each other, and each connecting rod is rotatably connected to the thickened plate.

[0007] Furthermore, the connecting rod is threaded, and nuts are connected to both sides of the connecting rod corresponding to the limiting block.

[0008] Furthermore, the connecting rod is provided with threads, and a limiting nut and a fixing nut are respectively provided on both sides of the connecting rod corresponding to the limiting block. An elastic element is provided between the limiting nut and the limiting block, and the elastic element applies a force toward the thickened plate to the limiting nut.

[0009] Furthermore, a rotatable drive shaft B is installed inside the thickened plate, and the connecting rod is fixedly connected to the drive shaft B.

[0010] Furthermore, an independent gripping pin is fixedly installed on the clamping arm. When the thickened plate is in contact with the clamping plate, the tip of the independent gripping pin is on the same plane as the tips of all the plate-side gripping pins on the thickened plate.

[0011] Furthermore, a second independent gripping pin is fixedly installed on the clamping arm. The second independent gripping pin is located between the independent gripping pin and the clamping plate, and the tip of the second independent gripping pin is on the same plane as the tips of all the plate-side gripping pins on the clamping plate.

[0012] Furthermore, a movable gripper is fixedly installed on the clamping arm. The movable gripper is movable and has two rated positions when it moves. When the movable gripper is in one rated position, its tip is on the same plane as the tips of all the plate-face grippers on the clamping plate. When the movable gripper is in the other rated position, the thickened plate is in contact with the clamping plate, and at this time the tip of the movable gripper is on the same plane as the tips of all the plate-face grippers on the thickened plate.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In this invention, by providing a movable thickened plate, the thickness of the clamping plate can be changed, thereby adapting to different size requirements. Specific embodiments are described below.

[0020] like Figure 1-3 As shown, a multi-functional overhead crane clamping plate device for calcining aluminum is specifically as follows: The device includes: a clamping arm 2, a clamping plate 3, a thickened plate 4, plate surface gripping nails 6, and a transmission module; The clamping plate 3 is fixedly connected to a plurality of clamping arms 2, and a plurality of plate surface gripping nails 6 are installed on the clamping plate 3; The thickened plate 4 is mounted on the clamping arm 2 via a transmission module, and a plurality of plate surface gripping nails 6 are mounted on the thickened plate 4; Both the clamping plate 3 and the thickened plate 4 include a clamping end and a supporting end. The supporting end is the end close to the clamping arm 2, and the clamping end is the end away from the clamping arm 2. The thickened plate 4 has two rated positions when it moves; when the thickened plate 4 is in one rated position, the supporting end of the thickened plate 4 is in contact with the clamping arm 2, and the plate surface gripping nail 6 on the thickened plate 4 and the plate surface gripping nail 6 on the clamping plate 3 are located on the same plane; when the thickened plate 4 is in the other rated position, the supporting end of the thickened plate 4 is in contact with the clamping end of the clamping plate 3. The transmission module is used to drive the thickened plate 4 to move between two rated positions.

[0021] like Figure 2 As shown in the embodiment of the present invention, the thickened plate 4 includes a nail-grabbing plate, a vertical plate 41, a horizontal plate 42, and a support plate 43. The two vertical plates 41 and the two horizontal plates 42 are fixedly connected to each other to form a thickened frame. The nail-grabbing plate is fixedly connected to the thickened frame. The support plate 43 is fixedly installed inside the thickened frame. One end of the support plate 43 is attached to the nail-grabbing plate, and the other end of the support plate 43 can be attached to the clamping arm 2.

[0022] Furthermore, the clamping arm 2 is provided with a groove 15 corresponding to the thickened plate 4, so that when the supporting end of the thickened plate 4 is in contact with the clamping arm 2, the plate surface gripping nail 6 on the thickened plate 4 and the plate surface gripping nail 6 on the clamping plate 3 are located on the same plane.

[0023] Furthermore, to enhance the structural stability of the overall thickened frame, the thickened plate 4 is also provided with a number of reinforcing plates 44 that are perpendicular to the support plate 43.

[0024] like Figure 3 As shown, in some embodiments of the present invention, the thickness of the support plate 43 is greater than that of the other plates in the thickened frame shown, so that the support plate 43 serves as the support component for the entire clamping plate 3.

[0025] like Figure 1As shown, in some embodiments of the present invention, the transmission module includes a connecting rod 9, a limiting block 12, a transmission shaft A7, and a drive 14; the output shaft of the drive 14 is connected to two transmission shafts A7 through a gearbox, the two transmission shafts A7 rotate in the same direction, and both ends of the transmission shaft A7 are fixedly connected to the limiting block 12. A connecting rod 9 is inserted in each limiting block 12, and the connecting rod 9 can rotate with the transmission shaft A7. Each connecting rod 9 is parallel to each other, and each connecting rod 9 is fixedly connected to the transmission shaft B8 in the thickened plate 4, and the transmission shaft B8 can rotate within the thickened plate 4.

[0026] With the above settings, the drive shaft A7 can be rotated by the drive 14, which in turn drives the drive shaft B8 to rotate via the connecting rod 9, thereby moving the entire thickened plate 4 to the clamping plate 3, thus achieving the thickening effect.

[0027] Furthermore, in some embodiments of the present invention, the connecting rod 9 is provided with threads, and nuts are connected to both sides of the connecting rod 9 corresponding to the limiting block 12, so that the actual length of the connecting rod 9 can be adjusted by means of the nuts.

[0028] Furthermore, in some embodiments of the present invention, the connecting rod 9 is provided with threads, and a limiting nut 10 and a fixing nut 13 are respectively provided on both sides of the connecting rod 9 corresponding to the limiting block 12. An elastic element 11 is provided between the limiting nut 10 and the limiting block 12. The elastic element 11 applies a force toward the thickened plate 4 to the limiting nut 10. The actual length of the connecting rod 9 can be adjusted by the fixing nut 13, and the elasticity of the elastic element 11 can be adjusted by the limiting nut 10.

[0029] Furthermore, such as Figure 3 As shown, in some embodiments of the present invention, an independent gripping nail 1 is fixedly installed on the clamping arm 2. When the thickened plate 4 is in contact with the clamping plate 3, the tip of the independent gripping nail 1 and the tips of all the plate-side gripping nails 6 on the thickened plate 4 are located on the same plane. The independent gripping nail 1 can play a role in stabilizing the carbon block in actual use.

[0030] Furthermore, such as Figure 4 As shown, in some embodiments of the present invention, a second independent gripping nail 101 is also fixedly installed on the clamping arm 2. The second independent gripping nail 101 is located between the independent gripping nail 1 and the clamping plate 3. The tip of the second independent gripping nail 101 is on the same plane as the tips of all the plate-side gripping nails 6 on the clamping plate 3. In practical applications, the independent gripping nail 1 and the second independent gripping nail 101 correspond to carbon blocks of different sizes.

[0031] It should be noted that the functions of independent gripper 1 and second independent gripper 101 can also be replaced by retractable independent grippers: A movable gripper is fixedly installed on the clamping arm 2. The movable gripper is movable and has two rated positions when it moves. When the movable gripper is in one rated position, its tip is on the same plane as the tips of all the plate-side grippers 6 on the clamping plate 3. When the movable gripper is in the other rated position, the thickened plate 4 is in contact with the clamping plate 3, and at this time the tips of the movable gripper and the tips of all the plate-side grippers 6 on the thickened plate 4 are on the same plane.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
