Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis production, in particular to a small box clamp adjustment tool for aluminum electrolysis production. Background Art

[0002] In aluminum electrolysis production, the small box clamp is a key component for fixing the anode group. It is used to connect the anode guide rod and the horizontal busbar. When replacing the anode, lifting the busbar, starting a new slot, etc., it needs to be adjusted to loosen and fix the anode group. These operations are very critical for aluminum electrolysis production and must be taken seriously. Any carelessness will cause major problems, especially the adjustment of the small box clamp. On the one hand, it is necessary to quickly adjust the small box clamp to reduce the operation time. On the other hand, it is necessary to improve the operation quality and ensure the tightness of the small box clamp. In the existing operation, in order to improve the adjustment speed of the small box clamp, the operator often stands on the slot cover plate with a quick wrench to adjust it. This operation method has problems such as personal injury caused by high-temperature flue gas and high safety risks in high-altitude operations. In order to ensure the tightening strength of the small box clamp, a large wrench is generally used for re-tightening. Due to limited space during operation, the worker needs to remove the large wrench every time the screw of the small box clamp is rotated about 120°, return to the starting point, re-place the wrench, and repeat this operation, which not only increases the workload, but also makes the operation inefficient.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

The plate 5 is located on the same circle, the top and bottom surfaces of the arc-shaped guard plate 5 are fixedly connected to the shell 2 respectively, and the center of the arc-shaped guard plate 5 overlaps with the center of the ratchet gear 3; the connecting mechanism includes a connecting sleeve 6, a force-bearing rod 7 and a connecting rod 8, one end of the force-bearing rod 7 is inserted into the connecting sleeve 6, and the other end is fixedly connected to the connecting rod 8, an angle is set between the force-bearing rod 7 and the connecting rod 8, and a through pin hole is set on the connecting sleeve 6 and the force-bearing rod 7, and a pin 9 is inserted in the pin hole, and the end of the connecting rod 8 away from the force-bearing rod 7 is fixedly connected to the handle 1.

[0026] The top surface and the bottom surface of the arc-shaped guard plate 5 are fixedly connected to the upper plate 10 and the lower plate 11 respectively.

[0027] The center of the ratchet gear 3 overlaps with the axis of the built-in wrench 4, and the outer end of the ratchet gear 3 is close to the arc-shaped guard plate 5 but not in contact with it.

[0028] The spacings between adjacent arc-shaped guard plates 5 are equal.

[0029] A gear stopper 12 cooperating with the ratchet gear 3 is further provided in the housing 2 , and a rotating shaft 13 of the gear stopper 12 is fixedly connected to the upper plate 10 and the lower plate 11 respectively.

[0030] The inner circular walls of the upper plate 10 and the lower plate 11 of the shell 2 are symmetrically provided with mounting grooves 17, the axis of which overlaps with the diameter of the upper plate 10 or the lower plate 11. The upper plate 10 or the lower plate 11 is also provided with an anti-slip mechanism, which is in an inverted "J" shape and includes a baffle 14 and connecting vertical plates 15 arranged parallel to both ends of the baffle 14. The bottom ends of the connecting vertical plates 15 are symmetrically provided with plug plates 18, which are respectively inserted into the mounting grooves 17 of the connecting vertical plates 15.

[0031] The projections of the axes of the ratchet gear 3, the built-in wrench 4, the baffle 14, the connecting sleeve 6, the force-bearing rod 7, the connecting rod 8 and the handle 1 are on the same straight line.

[0032] The included angle between the force-bearing rod 7 and the connecting rod 8 is 115-125°, and the included angle between the connecting rod 8 and the handle 1 is greater than 120°.

[0033] A cavity 16 matching with the stress-bearing rod 7 is arranged in the connecting sleeve 6 .

[0034] The sum of the heights of the adjusting mechanism and the anti-slipping mechanism is less than the height of the screw and nut of the small box fixture.

[0035] During operation, just put the built-in spanner 4 on the screw and nut of the small box fixture and it can be used.

[0036] Except for the force-bearing rod 7, all other parts of the utility model are made of stainless steel. The selection of dimensional data ensures that the utility model has sufficient strength while adapting to the strong magnetic field environment of aluminum electrolysis production, reducing the labor intensity of workers. The built-in spanner 4 is square and made of high-strength stainless steel. Its size matches the size of the screw nut of the small box fixture used in the electrolytic cell; the ratchet gear 3 is fixedly connected to the outside of the built-in spanner 4 and is at the same height as the built-in spanner 4; the gear stop 12 is matched with the ratchet gear 3, so that the ratchet gear 3 drives the built-in spanner 4 to rotate only in one direction; the sum of the heights of the adjustment mechanism and the anti-slip mechanism is less than the height of the screw nut of the small box fixture. The design of the anti-slip mechanism and the height limitation ensure that the built-in spanner 4 is stably sheathed outside the screw nut of the small box fixture when the tool is used, and will not fall off when the tool rotates.

[0037] The connecting sleeve 6 is a stainless steel round tube with an outer diameter greater than 35 mm and a wall thickness greater than 3 mm. The front end is welded to the shell 2. The force-bearing rod 7 is a steel rod with a diameter slightly smaller than the inner diameter of the connecting sleeve 6 and the same length as the connecting sleeve 6. The connecting sleeve 6 and the force-bearing rod 7 are both provided with pin holes in the up and down directions. The latch 9 passes through the pin holes to lock the connecting sleeve 6 and the force-bearing rod 7 together. The design of the connecting structure enables the adjusting mechanism to be flexibly disassembled so as to be flipped in the vertical direction. When flipping, the latch 9 is pulled out, and the adjusting mechanism is twisted to rotate the connecting sleeve 6 180° on the force-bearing rod 7, and then the latch 9 is inserted to re-lock the connecting structure. At the same time, the anti-slip mechanism interchanges the positions of the upper plate 10 and the lower plate 11.

[0038] The connecting rod 8 is a stainless steel round tube with an outer diameter and wall thickness equal to those of the connecting sleeve 6. The front end is welded to the force-bearing rod 7, and the tail is connected to a handle 1. The handle 1 is also a stainless steel round tube with an outer diameter and wall thickness equal to those of the connecting sleeve 6. The surface of the handle 1 is engraved with anti-skid patterns. The design of the anti-skid patterns makes the operator more stable when using the tool, and it is not easy to slip out of the hand, reducing the safety risk. The angle between the connecting rod 8 and the force-bearing rod 7 is 120±5°, and the angle between the connecting rod 8 and the handle 1 is greater than 120°. The setting of this angle is to improve the overall coordination of the tool and make it more flexible when used.

[0039] A specific application of this embodiment is:

[0040] In a certain 500kA aluminum electrolysis production, the diameter of the screw nut of the small box fixture is 38mm and the height is 50mm. The built-in wrench 4 of the utility model has an inner diameter of 38mm and a height of 32mm, the height of the anti-slip mechanism is 12mm, the thickness of the shell 2 is 6mm, and the total height of the adjustment mechanism and the anti-slip mechanism is 50mm; the length of the connecting sleeve 6 and the force rod 7 are both 25cm, the connecting sleeve 6, the connecting rod 8, and the handle 1 are all stainless steel round tubes with an outer diameter of 40mm and a wall thickness greater than 4mm, the length of the connecting rod 8 is 1.8m, and the length of the handle 1 is 35cm.

[0041] When loosening and tightening the small box fixture, the operator only needs to hold the utility model tool and put the built-in spanner 4 on the screw nut of the small box fixture from above. At this time, the anti-slip mechanism is naturally located on the top of the nut. The operator holds the handle 1 with both hands and pushes it horizontally. When the handle 1 is close to the electrolytic cell and cannot move forward, it is pulled back. At this time, the built-in spanner 4 will not rotate. Repeated operations can complete the unidirectional adjustment. When the small box fixture needs to be adjusted in the opposite direction, unplug the pin 9, rotate the adjustment mechanism 180°, reinsert the pin 9, and interchange the positions of the upper plate 10 and the lower plate 11 of the anti-slip mechanism, and continue the above operation.
