Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum electrolysis production, in particular to an anode guide rod anti-falling device for an aluminum electrolysis multifunctional overhead crane. Background Art
[0002] Anodes need to be replaced frequently during the aluminum electrolysis production process. Due to the heavy weight of the anodes, a multifunctional overhead crane is generally used to lift and replace them through the anode mechanism.
[0003] During hoisting, the anode mechanism moves downward to leave the upper limit position, and after the anode clamp at the end of the anode mechanism clamps the anode guide rod, the anode mechanism moves upward to return to the upper limit position to hoist the anode. Since the stroke of the anode clamp is controlled by the extension and contraction of the oil cylinder, when the anode clamp clamps the anode guide rod, the oil cylinder is in a tightened state. At this time, if the operator of the multi-functional overhead crane makes a mistake and the oil cylinder rod extends quickly, the anode clamp will loosen the anode guide rod, and the anode guide rod will fall off, causing the anode to be unable to be hoisted or fall to the ground during the hoisting process, reducing the operating efficiency and posing a greater safety hazard.
[0004] In order to prevent the anode guide rod from falling off due to misoperation during the anode replacement process, a device for preventing the anode guide rod from falling off has appeared in the prior art. However, most manufacturers' anode guide rod anti-falling devices are currently controlled by a cylinder, an electromagnetic push rod or an electromagnetic valve, and the control system and structure are relatively complex, prone to failure during use, and have high maintenance costs in the later stage. In addition, the existing anode guide rod anti-falling devices usually require experienced operators to operate correctly, and there is also a certain probability of misoperation, resulting in the anode falling to the ground, which fails to fundamentally eliminate the problem of anode guide rod falling off. Utility Model Content
[0005] The purpose of the utility model is to provide an anode guide rod anti-falling device for an aluminum electrolysis multifunctional overhead crane to solve the problems existing in the above-mentioned prior art. The anode clamp is automatically locked by a mechanical structure to achieve the effect of preventing the anode guide rod from falling off, improve the efficiency of anode replacement operations, and reduce safety hazards. In addition, the device has a simple structure, does not require complex electrical control, and has low technical requirements for the operator.
[0006] To achieve the above purpose, the utility model provides the following solutions:
[0007] The utility model provides an anode guide rod anti-falling device for a multifunctional overhead crane for aluminum electrolysis, comprising a mounting plate, a baffle, a connecting rod mechanism, a locking plate and an elastic connecting mechanism, wherein the mounting plate is used to be fixed on the anode frame at a position close to the anode mechanism, and the baffle is used to be fixed on the anode mechanism at a position close to the anode clamp; the connecting rod mechanism is arranged on the mounting plate, and the connecting rod mechanism comprises an upper connecting rod, a middle connecting rod and a lower connecting rod that are rotatably connected in sequence from top to bottom, the middle part of the upper connecting rod is rotatably connected to the mounting plate through a first rotating shaft, and the end of the lower connecting rod away from the middle connecting rod is fixedly connected to the locking plate and is connected to the locking plate through a second rotating shaft. The rotatable connection with the mounting plate; one end of the elastic connection mechanism is a fixed end, and the other end is a movable end, and the movable end is connected with the connecting rod mechanism. When the anode mechanism leaves the upper limit position, the baffle plate is separated from the upper connecting rod, and the elastic connection mechanism drives the locking plate to rotate downward around the second rotating axis through the connecting rod mechanism, so that the anode clamp is in an open state. When the anode mechanism is located at the upper limit position, the baffle plate abuts against the upper connecting rod, so that the connecting rod mechanism pulls down the elastic connection mechanism and drives the locking plate to rotate upward around the second rotating axis, thereby putting the anode clamp in a locked state.
[0008] Preferably, the elastic connection mechanism includes an elastic connector and a fixed block, the fixed block is used to be fixed on the anode frame at a position above the mounting plate, one end of the elastic connector is connected to the fixed block, and the other end is connected to an end of the upper connecting rod close to the middle connecting rod.
[0009] Preferably, the elastic connecting member is a spring.
[0010] Preferably, the fixing block can be fixed to the anode frame by welding.
[0011] Preferably, the upper connecting rod is rotatably connected to the middle connecting rod via a first pin.
[0012] Preferably, the lower connecting rod is rotatably connected to the middle connecting rod via a second pin shaft.
[0013] Compared with the prior art, the utility model has achieved the following technical effects:
[0014] The utility model provides an anode guide rod anti-falling device for an aluminum electrolysis multifunctional overhead crane, comprising a mounting plate, a baffle, a connecting rod mechanism, a locking plate and an elastic connecting mechanism. When in use, the device is mounted on the anode frame. When the anode mechanism leaves the upper limit position, that is, the anode mechanism moves downward, the baffle is separated from the upper connecting rod. At the same time, the elastic connecting mechanism drives the locking plate to rotate downward around the second rotating axis through the connecting rod mechanism, so that the anode clamp is in an open state. At this time, the anode clamp can clamp the anode guide rod. After clamping the anode guide rod, the anode mechanism moves upward. When the anode mechanism is located at the upper limit position, the baffle abuts against the upper connecting rod, so that the connecting rod mechanism pulls down the elastic connecting mechanism and drives the locking plate to rotate upward around the second rotating axis, so that the anode clamp is in a locked state. At this time, the anode guide rod is firmly fixed in the anode clamp, achieving the effect of preventing the anode guide rod from falling off.
[0015] The device utilizes the up and down movement of the anode mechanism to automatically control the lifting and lowering of the baffle. At the same time, under the elastic force of the elastic connection mechanism, the baffle can drive the locking plate to rotate through the connecting rod mechanism, thereby automatically locking or opening the anode clamp. Without affecting the normal operation of the anode clamp, it is ensured that the anode clamp will not be disengaged due to emergencies during the lifting process, avoiding the problem of the anode guide rod falling off due to the disengagement of the anode clamp, improving the efficiency of the anode replacement operation, and reducing safety hazards. In addition, the device has a simple structure, does not require complex electrical control, and has low technical requirements for the operator. BRIEF DESCRIPTION OF THE DRAWINGS
