Description

Technical Field

[0001] The utility model relates to a compensator of a clamp, in particular to a compensator of a clamp used for clamping a carbon block by a multifunctional overhead crane. Background Art

[0002] The original multifunctional overhead crane clamp determines the length of the clamp beam according to the type and quantity of the blocks loaded in the furnace and the length of the material box in the furnace chamber. The clamp is a customized device with a certain gap between the blocks, which can clamp several types of carbon blocks with small block deviations. The customization cost of a single-model clamp is about tens of thousands of yuan, which is expensive. When the deviation of the two block types clamped in the furnace is large, due to the limited clamping distance of the clamp, 7 blocks of 700mm width carbon blocks for self-use and 6 blocks of 740mm width carbon blocks for export can be clamped. If a single-block type single clamp is purchased, the cost of purchasing the clamp is high and the replacement is also troublesome, resulting in passive production of roasting and loading, and it cannot be used for carbon blocks of multiple specifications. For this reason, a clamp compensation device is needed to enable it to meet the clamping of carbon blocks of multiple specifications. Utility Model Content

[0017] The compensator includes a static steel structure 4, a dynamic steel structure 5 and a supporting steel structure 7. The static steel structure 4 is fixed to the clamp arm 2. The dynamic steel structure 5 and the static steel structure 4 are rotatably connected through the supporting steel structure 7. The static steel structure 4 is provided with annularly distributed adjustment holes 8. The supporting steel structure 7 is provided with limit holes corresponding to the positions of the adjustment holes 8. Pins 9 penetrate the adjustment holes 8 and the limit holes to limit the supporting steel structure 7. When the clamp requires a wider clamping distance, the overhead crane clamp 1 falls to the ground, and the static steel structure 4, dynamic steel structure 5 and clamp arm 2 at the bottom touch the ground. The bottom of the dynamic steel structure 5 can contact a movable platform, such as a rail car, and the pins 9 are manually removed. After all the pins 9 are removed, the overhead crane clamp 1 is lifted up, and the dynamic steel structure 5 is lifted up under the action of gravity. 5 is always in contact with the rail car, the angle of the supporting steel structure 7 is tilted, driving the dynamic steel structure 5 and the rail car to move, as the overhead crane clamp 1 is lifted up, the limit hole will coincide with the different adjustment holes 8, after the adjustment is completed, the pin 9 limits the supporting steel structure 7 through the adjustment hole 8 and the limit hole to keep the angle, completing the debugging of the dynamic steel structure 5, the distance between the dynamic steel structure 5 and the static steel structure 4 is shortened, and the distance between the clamps 3 is increased, which can adapt to the clamping of carbon blocks of different specifications, and vice versa, the distance between the dynamic steel structure 5 and the static steel structure 4 can be widened, the distance between the clamps 3 is reduced, and the clamping distance is compensated, and the operation is simple and convenient, the steel structure is stable, can withstand the pressure and load-bearing capacity within the operating range, and meet the operating requirements.

[0018] In a preferred embodiment, the static steel structure 4 is fixed to the clamp arm 2 by bolts, and the static steel structure 4 and the dynamic steel structure 5 are rotatably connected to the supporting steel structure 7 by the rotating shaft 6. A bearing is installed on the outer side of the rotating shaft 6, and the outer side of the bearing is connected to the supporting steel structure 7, so that the supporting steel structure 7 can rotate. The closer the angle of the supporting steel structure 7 is to vertical, the shortest distance between the static steel structure 4 and the dynamic steel structure 5 is, and the closer the angle of the supporting steel structure 7 is to horizontal, the longest distance between the static steel structure 4 and the dynamic steel structure 5 is, so as to adjust the compensation and meet the clamping distance.

[0019] In a preferred embodiment, the number of supporting steel structures 7 on one side is not less than two, and the static steel structure 4, the dynamic steel structure 5 and the supporting steel structure 7 form a deformable parallelogram structure. The static steel structure 4 and the dynamic steel structure 5 always remain vertical and parallel. The layout spacing and number of the supporting steel structures 7 are set according to the force during clamping. The parallelogram structure composed of the static steel structure 4, the dynamic steel structure 5 and the supporting steel structure 7 can not only meet the condition that the dynamic steel structure 5 is always vertical, but also has a large compensation range, a simple structure and low maintenance cost.

[0020] In a preferred embodiment, the adjustment holes 8 are distributed in a ring shape with the rotating shaft 6 as the center. When the supporting steel structure 7 rotates, the limit holes will be aligned with different adjustment holes 8, and the pins 9 are inserted to form a fixation. The supporting steel structure 7 rotates with the rotating shaft 6 as the center. Therefore, the travel trajectory of the limit holes is an arc with the rotating shaft 6 as a circle. The adjustment holes 8 need to be distributed on the travel trajectory of the limit holes to ensure the insertion of the pins 9. A nut is provided at the other end of the pin 9. After the pin 9 is inserted into the limit hole and the adjustment hole 8 to form a fixation, it is locked by the nut to prevent it from falling off.
