Detailed Implementation

[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 As shown, Figure 1 This is a schematic diagram of the first embodiment of the lifting device used for the traveling track of the multi-functional overhead crane in aluminum electrolysis.

[0024] The lifting device for the traveling track of a multi-functional overhead crane for aluminum electrolysis, as described in this utility model, includes a first positioning plate 1 and a second positioning plate 2. The first positioning plate 1 and the second positioning plate 2 are arranged in parallel. A first connecting rod 3 is vertically fixed on the first positioning plate 1, and a second connecting rod 4 is vertically fixed on the second positioning plate 2. One end of the first connecting rod 3 is detachably connected to the second positioning plate 2, and the second connecting rod 4 is detachably connected to the first positioning plate 1, thereby realizing the detachable connection between the first positioning plate 1 and the second positioning plate 2. A first track positioning block 5 is provided on the first positioning plate 1, and a second track positioning block 6 is provided on the second positioning plate 4. The first track positioning block 5 and the second track positioning block 6 are arranged symmetrically. The first connecting rod 3 is located between the second connecting rod 4 and the first track positioning block 5.

[0025] When the first positioning plate 1 and the second positioning plate 2 are fixedly connected by the first connecting rod 3 and the second connecting rod 4, the travel track is set between the first positioning plate 1 and the second positioning plate 2, and the first track positioning block 5 and the second track positioning block 6 are respectively set on both sides of the travel track to clamp and support the travel track. The cross-section of the travel track is generally I-shaped, consisting of an upper horizontal plate, a lower horizontal plate and a connecting plate. The upper horizontal plate and the lower horizontal plate are parallel and connected by the connecting plate. Steel grooves are formed on both sides of the connecting plate. The first track positioning block 5 and the second track positioning block 6 are respectively inserted into the steel grooves on both sides of the travel track, and the upper horizontal plate at the top of the travel track is contacted and lifted at the bottom. The lifting ring of the lifting device is sleeved on the second connecting rod 4, and the lifting ring is pulled by the sling to realize the lifting operation of the travel track.

[0026] In this embodiment, the second positioning plate 2 is provided with a first connecting hole, the first connecting rod 3 is disposed in the first connecting hole, and a locking nut 7 is threadedly connected to the first connecting rod 3. The second positioning plate 2 is disposed between the first positioning plate 1 and the locking nut 7. By turning the locking nut 7 against the second positioning plate 2, the second positioning plate 2 can be moved toward the first positioning plate 1, thereby achieving the clamping effect of the first positioning plate 1 and the second positioning plate 2 on the traveling track.

[0027] The first positioning plate 1 is provided with a hoisting positioning block 8, which is located above the end of the second connecting rod 4 near the first positioning plate 1. The hoisting positioning block 8 is in contact with the end of the second connecting rod 4, and is used to bear the upward pulling force when the second connecting rod 4 is hoisted.

[0028] The length of the second connecting rod 4 is less than the width of the travel track, so as to prevent the second connecting rod 4 from touching the first positioning plate 1, thereby ensuring that the first positioning plate 1 and the second positioning plate 2 or the first track positioning block 5 and the second track positioning block 6 can fit and clamp tightly with both sides of the travel track.

[0029] Generally, the first connecting rod 3 and the second connecting rod 4 are arranged in parallel. The extension direction of the first track positioning block 5 and the second track positioning block 6 is not perpendicular to the plane containing the axes of the first connecting rod 3 and the second connecting rod 4. That is, the first track positioning block 5 and the second track positioning block 6 extend at an angle. When using two-point hoisting, it can be ensured that while the first track positioning block 5 and the second track positioning block 6 horizontally support the traveling track, the sling is located on the plane containing the axes of the first connecting rod 3 and the second connecting rod 4, thereby ensuring the balance and stability of the hoisting.

[0030] This utility model is ingeniously designed and highly reliable; it has a reasonable structure, is easy to maintain; it is easy to operate, highly usable, and highly safe; it has high work efficiency, saves time and effort, and ensures the personal safety of operators; it is easy to install and disassemble, has a locking function, and is of reliable strength; this utility model effectively reduces the labor intensity of workers and improves work efficiency; specifically, the first positioning plate and the second positioning plate are fixed on both sides of the traveling track by the positioning plate connecting bolts and locking nuts, and the hoisting fixing rod is connected by the lifting ring and the sling, and the upper end is fixed by the positioning block of the hoisting fixing rod, thereby hoisting the aluminum electrolysis multi-functional overhead crane traveling track.

[0031] Example 2

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, Figure 2 This is a front view of the structure of the second embodiment of the lifting device used for the traveling track of the multi-functional overhead crane in aluminum electrolysis; Figure 3 This is an outer structural view of the first positioning plate in Embodiment 2; Figure 4 This is an inner structural view of the first positioning plate in Embodiment 2.

[0033] This embodiment is a further improvement on the first embodiment. The improvement is that the first positioning plate 1 is provided with a second connecting hole, the first connecting rod 3 and the second connecting rod 4 are of equal length, and the second connecting rod 4 is disposed in the second connecting hole, so that when the locking nut is turned to push against the second positioning plate 2, the first positioning plate 1 can move linearly along the second connecting rod 4.

[0034] Preferably, both the first positioning plate 1 and the second positioning plate 2 are provided with clamping and adjusting components. The first positioning plate 1 is connected to the first track positioning block 5 through the clamping and adjusting components, and the second positioning plate 4 is connected to the second track positioning block 6 through the clamping and adjusting components. After the first positioning plate 1 and the second positioning plate 2 are adjusted into position, the positions of the first track positioning block 5 and the second track positioning block 6 are adjusted so that the first positioning plate 1, the second positioning plate 2, the first track positioning block 5 and the second track positioning block 6 are all in contact with the traveling track, thereby further improving the stability and structural strength between the present invention and the traveling track, and ensuring the smooth progress of hoisting.

[0035] Specifically, the clamping adjustment assembly includes a guide post 9 and an adjustment post 10, which are arranged in parallel. The first positioning plate 1 and the second positioning plate 2 are respectively provided with guide holes and adjustment holes. The guide post 9 and the adjustment post 10 are both arranged perpendicularly to the first positioning plate 1 and the second positioning plate 2. One end of the guide post 9 is vertically fixed on the first track positioning block 5 or the second track positioning block 6. The guide post 9 is set in the corresponding guide hole. One end of the adjustment post 10 is rotatably connected to the first track positioning block 5 or the second track positioning block 6. The adjustment post 10 is threadedly connected in the adjustment hole.

[0036] By rotating the adjusting column 10, the distance between the first positioning plate 1 and the first track positioning block 5 or between the second positioning plate 4 and the second track positioning block 6 can be adjusted. Thus, after the first positioning plate 1 and the second positioning plate 2 are clamped on both sides of the traveling track by the locking nut 7, rotating the adjusting column 10 will cause the first track positioning block 5 or the second track positioning block 6 to extend into the steel groove and fit against both sides of the connecting plate, thereby forming a good clamping and fixing effect.

[0037] Preferably, the same clamping and adjusting assembly is provided with two guide posts 9 and one adjusting post 10. The two guide posts 9 are symmetrically arranged on both sides of the adjusting post 10, and the two guide posts 9 are fixedly arranged at both ends of the first track positioning block 5 or the second track positioning block 6, thereby ensuring the stability of the clamping and adjusting process.

[0038] Preferably, a first bonding layer 11 is provided on the end face of the first track positioning block 5 away from the first positioning plate 1 and on the end face of the second track positioning block 6 away from the second positioning plate 4. The first bonding layer 11 is a rubber layer. The first track positioning block 5 or the second track positioning block 6 contacts and bonds with the travel track through the first bonding layer 11, thereby increasing the static friction force during clamping and fixing, and thus improving the hoisting stability.

[0039] Generally, a second bonding layer 12 is provided on the inner side of the first positioning plate 1 and the second positioning plate 2. The second bonding layer 12 is disposed between the second connecting rod 4 and the first track positioning block 5 or the second track positioning block 6. The second bonding layer 12 is a rubber layer. The first positioning plate 1 or the second positioning plate 2 contacts and adheres to the traveling track through the second bonding layer 12 to improve the static friction force during clamping and fixing, thereby improving the hoisting stability.

[0040] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
