Description

Technical Field

[0001] The utility model relates to the technical field of smelting and feeding, in particular to a starting pole piece unit oil cylinder fixing support device. Background Art

[0002] The crane lifts the storage box with the starting electrode sheets onto the conveyor rollers. At the plate-taking position of the conveyor, the starting electrode sheets are sucked out of the box and sent to the shaping device. The shaping device flattens, corrugates and corrects the starting electrode sheets. The lifting ears are sucked out of the lifting ear storage box and sent to the assembly table. At the same time, the conductive rods are sent to the assembly table by the conductive rod unit. The three become cathode plates after being assembled with the ears. The cathode plates are turned into a vertical state by the plate turning machine. The lifting conveyor lifts the cathode plates piece by piece to the plate arrangement conveyor for plate arrangement. The starting electrode sheets with a set number of pole pitches are transported to the lifting position by the transfer trolley and then lifted to the electrolytic cell by the crane.

[0003] The movable horizontal oil cylinder of the starting pole piece unit in the electrolysis workshop adopts an integral support to install the outer ear shaft of the oil cylinder, and the inner hole of the support and the shaft are clearance-matched. Because the oil cylinder is installed upside down, and the maximum pressure of the hydraulic system is 10-12Mpa, the working pressure is high, and the opening action is frequent, resulting in serious wear of the support hole and the shaft. In addition, due to the tight production tasks and high work intensity, the wear of the shaft hole is aggravated, forming a gap of 1-3mm. When the oil cylinder is working, the shaft and the mounting support will instantly collide and make abnormal sounds, which can aggravate the loss of the oil cylinder and accelerate the wear speed of the shaft. In addition, the vibration and beating of the oil cylinder will affect the production. The oil cylinder mainly performs hole punching processing on the ear of the starting pole piece. Due to the gap between the shaft and the support, it will cause uneven wear on both sides. When the oil cylinder is punched, it will cause deviation in the position of the ear of the starting pole piece, which seriously affects the processing performance.

[0004] At the same time, there are serious safety hazards. Due to the unreasonable design at this stage, the cylinder will generate outward pressure on the support seats on both sides when running. The supports on both sides are open to both sides during operation. After long-term operation, the cylinder ear shaft is in danger of falling off the support. Once it falls off, it will cause serious consequences, interrupting production and posing a safety hazard to surrounding personnel.

[0005] Moreover, when a gap is generated, the current practice is to use copper sheets to make arc-shaped gaskets and insert them into the gap between the shaft and the hole. However, this method is not easy to operate and is extremely inconvenient to install. Moreover, the gap cannot be fundamentally eliminated after installation. After running for a period of time, the gasket may become loose or fall off, and the problem cannot be fundamentally solved. Moreover, the production tasks in the electrolysis workshop are tight and the work intensity is high. Frequent maintenance will affect production and cause interruptions to production tasks. Moreover, the support is inconvenient to disassemble and install, and requires the cooperation of lifting, which poses a safety hazard. Moreover, since the ear shaft and the hydraulic cylinder are integrated, it is inconvenient and uneconomical to replace the ear shaft after wear. Replacing the support alone still only treats the symptoms and not the root cause, and the problem cannot be fundamentally and thoroughly solved. Utility Model Content

[0006] The utility model aims to provide a starting piece unit oil cylinder fixing support device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A starting piece unit oil cylinder fixed support device includes support components located on both sides of the oil cylinder, the two ends of the two groups of support components are connected by two tie rod screws respectively, and a bushing is installed in the middle of the two groups of support components, and the bushing is installed in cooperation with the shaft ear on the oil cylinder.

[0009] The support assembly comprises an upper support seat and a lower support seat which are arranged opposite to each other, and the upper support seat and the lower support seat have the same structure.

[0010] A through hole with a semicircular structure matching with the bushing is opened on the side wall at the middle position of the upper supporting seat and the lower supporting seat.

[0011] Both ends of the upper supporting seat and the lower supporting seat are provided with mounting holes matched with the pull rod screw.

[0012] Circular holes are arranged on the side walls at both ends of the upper supporting seat and the lower supporting seat, and fastening bolts are arranged on the circular holes.

[0013] The ends of the fastening bolts are threadedly connected to the anchor base of the foundation, and the fastening bolts are used for fixed connection between the upper support base, the lower support base and the foundation.

[0014] The pull rod screw is threadedly connected with a plurality of fastening nuts, and the fastening nuts 4 are used to adjust the distance between the two groups of support components.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1) After the implementation of the utility model, the drawbacks of clearance fit can be fundamentally solved. The split structure can tightly fix and lock the shaft. The problem of the gap between the ear shaft and the support seat is solved. At the same time, this method can provide a strong gripping force, solve the problem of the uneven force generated by the oil cylinder during drilling, causing the rotation and causing the inaccurate drilling position, and completely solve the problem caused by the gap in the shaft hole; reduce the failure rate, solve the problem of shaft beating, and eliminate safety hazards; and the split support seat is easy to install and maintain; at the same time, it reduces the replacement cycle of the support seat, reduces the wear rate of the shaft, and saves the cost of spare parts.

[0017] 2) The utility model adds four opposing adjustment rods for the support seat. The adjustment rods use four M24 through-threads. Each screw is equipped with eight nuts, which can lock the screws in four positions (inside and outside positions of each bearing seat). The support seat can be fixed and restricted in the horizontal direction, solving the need for the support seat to be horizontally limited. In addition, the use of the rod screw enhances the integrity, stability and durability of the structure. The rod screw can increase the restraining force in the horizontal direction, prevent the support seat from tilting outward when the oil cylinder is working, and play a role in limiting, fixing and strengthening the support seat, eliminating the sign of the ear shaft falling off the support seat.

[0018] 3) After the utility model was modified and installed, the use effect was good, the oil cylinder ran smoothly, and the support seat was no longer worn, which extended the service life of the equipment, reduced the probability of failure and shutdown, and reduced the number of times that production was affected. Moreover, after the support seat was modified, the processing accuracy of the pole piece lifting lug was improved, and the deviation problem of the pole piece drilling position was solved.

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-2As shown, the utility model provides a starting piece unit cylinder fixing support device, including support components located on both sides of the cylinder 7, the two ends of the two groups of support components are respectively connected by two tie rod screws 3, and the middle of the two groups of support components is installed with a bushing 6, which is installed in cooperation with the shaft ear on the cylinder 7.

[0025] The support assembly includes an upper support seat 1 and a lower support seat 2 which are arranged relatively. The upper support seat 1 and the lower support seat 2 are designed in a split type. They can be fixedly connected and fastened to the anchor seat by fastening bolts 5. The thickness of the upper support seat 1 and the lower support seat 2 is thickened. The actual thickness is twice the thickness of the working thickness of the oil cylinder shaft ear and the support surface. This method can enhance the strength of the support seat and stabilize the system. Since the upper support seat 1 and the lower support seat 2 are designed in an axisymmetric manner, if the working surface of the inner hole of the support seat is worn, the support seat can be turned over 180° and continued to be used. Since the shaft ear installation position only wears half of the position of the support seat, the other half can still be turned over and continued to be used. Save spare parts costs. The middle of the upper support seat 1 and the lower support seat 2 is the working surface for installing the bushing 6. The middle hole of the support seat is quenched to increase the local strength. The bushing 6 is a wearing part. If the bushing 6 is worn after a long period of operation, only the bushing 6 can be replaced. This method can extend the service life of the upper support seat 1 and the lower support seat 2.

[0026] The installed tie rod screw 3 is used in conjunction with the fastening nut 4. The fastening nut on the inner side can play a role of limiting adjustment and fastening, and the nut on the outer side can play a role of locking. The bushing 6 can be installed in conjunction with the cylinder shaft ear, and the gap can be adjusted to eliminate the interference fit. Through this matching installation method, the problem of the upper support seat 1 and the lower support seat 2 opening turning outward due to frequent starting of the cylinder can be eliminated, resulting in a reduction in the contact area between the cylinder shaft ear and the support seat, which poses a safety hazard. Through 4 groups of tie rod screws 3 and fastening nuts 4, the role of limiting fastening is played, eliminating the risk of the cylinder shaft ear falling off the support seat.

[0027] Since the oil cylinder is installed upside down, only the inner hole of the upper support seat 1 is seriously worn during actual operation. When the planed support seat is used for maintenance, only the pull rod screw 3, the fastening nut 4, and the fastening bolt 5 can be removed before the bushing 6 and the upper support seat 1 can be installed. There is no need to lift the oil cylinder for maintenance.
