Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for anode carbon blocks to enter and exit a furnace. Background Art

[0002] At present, most of the anode products of aluminum carbon anode enterprises are sold externally. Due to the different block types and supply quantities in the market, manufacturers need to adjust the furnace loading mode according to orders. Enterprises that produce aluminum anode blocks cannot adjust the size of the anode blocks because the size of the roasting kiln is fixed. However, in the production process, the filling rate of the anode blocks in each material box is the key to determining the energy consumption used in production. The higher the filling rate, the lower the unit electricity consumption and natural gas consumption under the same production cycle.

[0003] During the production process, an overhead crane is used to load the furnace, which can only place a fixed number of blocks. After placing a certain number of blocks, if the furnace chamber is still a certain width, it will be difficult to put in a small block. Conventionally, personnel are required to use a wire rope to adjust the carbon blocks and put them in, and then manually go down to the furnace chamber to remove the wire rope. However, when the cooked blocks are taken out of the furnace, the carbon blocks will reach a high temperature of more than 200 degrees Celsius, and personnel cannot enter the furnace chamber at all, resulting in the inability to take out the blocks that are loaded individually, and there are great safety hazards in the process of placing and taking out. Therefore, this application is proposed to efficiently carry out the operation of putting independent anode carbon blocks in and out of the furnace while ensuring safety. Utility Model Content

[0004] The utility model aims to provide an anode carbon block unloading fixture to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anode carbon block unloading fixture comprises two clamping plates, the two clamping plates are connected by a connecting piece and a movable support rod, and the movable support rod is rotatably connected to the two clamping plates through a supporting connection seat;

[0007] The connecting piece includes a control connecting seat, a driving arm and a lifting ring. The two clamps are respectively installed with the driving arms through the control connecting seat. The two driving arms are rotatably connected through a mounting pin at one end away from the clamp, and both ends of the mounting pin are fixed to the lifting ring.

[0008] As a further solution of the utility model: handle pull rods are installed on the top ends of the two clamping plates.

[0009] As a further solution of the utility model: a control member having the same installation and structure as the connecting member is installed between the two clamping plates, the lifting ring of the connecting member is bent downward, and the lifting ring of the control member is bent upward.

[0010] As a further solution of the utility model: the length of the movable support rod is less than the sum of the lengths of the two driving arms. When the two driving arms of the connecting member are bent toward a horizontal angle, the two splints are inclined with the movable support rod as a fulcrum, and the bottom spacing becomes smaller.

[0011] As a further solution of the utility model: a clamping nail located below the movable support rod is provided on the opposite side of the two clamping plates.

[0012] As a further solution of the utility model: the connecting seat is composed of two seat bodies and a shaft, the two seat bodies are provided with shaft holes, the shaft is rotatably installed in the shaft holes of the two seat bodies, and the driving arm is installed on the shaft.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

The operating handle pull rod opens the clamp. The crane electric hoist hook is used to pull the lifting ring upward. The lifting ring rises, and the clamp pins clamp the carbon block. The movable pull rod or wire rope is stressed to make the clamp clamp the carbon block, and the lifting and lowering actions begin.

[0015] 2. When the anode carbon block unloading fixture has two sets of independently driven wire hooks, the connecting parts and control parts are driven by driving different wire hooks to make the clamping plate in a clamping or releasing state according to different requirements, without the control of the handle pull rod.

[0021] See also Figures 1 to 4In the embodiment of the utility model, an anode carbon block unloading fixture includes two clamps 1, the two clamps 1 are connected by a connecting piece and a movable support rod 7, and the movable support rod 7 is rotatably connected to the two clamps 1 through a supporting connection seat 6;

[0022] The connecting piece includes a control connection seat 2, a driving arm 3 and a lifting ring 5. The two clamps 1 are respectively installed with the driving arms 3 through the control connection seat 2. The two driving arms 3 are rotatably connected at one end away from the clamp 1 through the mounting pin 4. Both ends of the mounting pin 4 are fixed to the lifting ring 5. By designing a new type of lightweight clamp, the clamp is hung on the hook of the overhead crane electric hoist, and the flexible clamping and lifting of the carbon block can be realized. Two wide clamps 1 are used. The opposite sides of the two clamps 1 are provided with clamping nails 8 located below the movable support rod 7. The bottom of the clamp 1 Four clamping nails 8 are installed at the bottom, and a movable support rod 7 with adjustable length is used on the upper part of the clamping nail 8 as the force point for lifting the splint 1. The middle part of the splint 1 adopts a V-shaped support rod with movable ends and the middle part, that is, a connecting piece. The overhead crane hook can be hung on the lifting ring 5 in the middle of the connecting piece. When the splint 1 is stuck on the two flat wide surfaces of the charcoal block, the overhead crane hoist hook is upward to give an open force to the upper part of the two splints 1. The splint 1 uses the movable support rod 7 as the fulcrum, and the bottom clamping nail 8 is closed inward to clamp the charcoal block. The heavier the charcoal block, the greater the clamping force, so that individual charcoal blocks can be put in and out of the furnace.

[0023] In a preferred embodiment, handle rods 9 are installed on the top of the two clamps 1. When placing the middle and bottom carbon blocks, there is a bolt hole on the top of each clamp 1, through which the handle rod 9 can be inserted to be inserted into the top filling of the middle or bottom carbon blocks, and the opening and closing of the clamps 1 can be controlled. For extra-large blocks, two sets of such clamps can be used for lifting at the same time.

[0024] In a preferred embodiment, a control member 10 with the same installation and structure as the connecting member is installed between the two splints 1. The lifting ring 5 of the connecting member is bent downward, and the lifting ring 5 of the control member 10 is bent upward. The length of the movable support rod 7 is less than the sum of the lengths of the two driving arms 3. When the two driving arms 3 of the connecting member are bent toward a horizontal angle, the two splints 1 are tilted with the movable support rod 7 as a fulcrum, and the bottom spacing becomes smaller. For a lifting device with two independently controllable wire cranes or electric hoists, the connecting member and the control member 10 can be connected separately. When lowering, the steel wire connecting the control member 10 is tensioned, and the steel wire assembled with the connecting member is in a relaxed state, resulting in the control member 10 being subjected to force to expand the clamping point of the splint 1 outward, so that the splint 1 opens at a larger angle when clamped, and the position is easier to calibrate. When lifting, the steel wire of the control member 1 is in a relaxed state, and the steel wire assembled with the connecting member is tensioned and lifted. At this time, the opening angle of the splint 1 becomes smaller, and the clamped carbon block moves without the control of the handle pull rod 9.

[0025] In a preferred embodiment, the connecting seat 2 is composed of two seat bodies and an axis. The two seat bodies are provided with axis holes. The axis can be rotatably installed in the axis holes of the two seat bodies. The driving arm 3 is installed on the axis. The connecting seat 2 serves as a rotating connecting structure and plays an important role in connecting the left and right sides, so that all its structures can only rotate on the same plane, maintaining the symmetry of the force points during clamping, thereby improving its clamping stability.

[0026] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0027] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
