Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick construction, and particularly to a fixture tool for hoisting refractory bricks. Background Art

[0002] In the daily repair station of coke oven doors, refractory bricks are frequently hoisted. Since refractory bricks are heavy, in the past, lifting straps were used to bind refractory bricks for hoisting. This method has a long maintenance time during the hoisting and handling process, requires a lot of labor, and has high safety risks and low efficiency. At the same time, the thickness of coke oven refractory bricks is relatively large, and it is difficult to balance the center of gravity of refractory bricks during hoisting with ordinary brick clamps, thus causing safety accidents.

[0005] To achieve the above object, the utility model provides a fixture tool for hoisting refractory bricks, which is characterized in that it includes a first connecting rod group and a second connecting rod group with a scissors structure: the upper ends of the first connecting rod group and the second connecting rod group are connected with suspension ropes, and chucks are arranged at the lower ends;

[0006] The first connecting rod group and the second connecting rod group are arranged in parallel, and their scissors mid-axes are connected by a pin shaft perpendicular to the connecting rod group;

[0007] A support plate extends inward from the bottom surface of the chuck; the chucks and support plates at the lower ends of the first connecting rod group and the chucks and support plates at the lower ends of the second connecting rod group together form a refractory brick clamping space.

[0008] When using the fixture tool, only need to place the refractory brick in the middle of the fixture, lift the four suspension ropes at the upper ends of the connecting rod group, and rely on gravity to tighten the fixture, so that the support plate is inserted into the left and right sides of the bottom of the refractory brick, and the chuck clamps the refractory brick, then the hoisting of the refractory brick can be realized. When using the fixture, almost no manual close-range operation is required. The refractory brick is clamped by two layers of scissors, and the center of gravity is stable, so it saves time and effort and has high safety.

[0009] Further, the first connecting rod group includes two first movable connecting rods arranged in a cross shape; the second connecting rod group includes two second movable connecting rods arranged in a cross shape; the chucks are respectively arranged at the lower ends of the first movable connecting rod and the second movable connecting rod and are integrally formed with the movable connecting rods. The distance between the first connecting rod group and the second connecting rod group is slightly smaller than the width of the refractory brick, so that the refractory brick can be stably supported.

[0010] Furthermore, the lengths of the first movable link and the second movable link are 900 mm respectively; the length of the chuck is 500 mm; the included angle between the first movable link or the second movable link and the chuck is 120°.

[0011] Furthermore, the end parts of the first link group and the second link group and the connection parts of the chuck are respectively connected by a horizontal axis perpendicular to the link group, so as to better ensure the synchronous operation of the two groups of links and further improve safety.

[0012] Furthermore, rope threading rings are arranged on the outer sides of the first link group, the second link group and the chuck, so that the fixture can also be used in combination with a sling.

[0013] Furthermore, the pallet is triangular to reduce the resistance when the pallet is inserted into the bottom of the refractory brick.
