Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment installation / maintenance technology, and specifically to a method for installing a sintering machine head wheel. Background Technology

[0002] Sintering is an important step in metallurgical engineering. The heavy weight of the equipment involved in sintering is a major challenge in the installation of mechanical equipment in metallurgical construction. Specifically, the head wheel of the sintering machine is heavy, and lifting machinery often cannot enter the plant for hoisting, making installation difficult. Typically (as in the installation method of the star wheel of the belt sintering machine head disclosed in CN 200910219850.X), it is necessary to borrow the upper trolley track of the sintering machine for simultaneous installation. This requires using other existing tracks, which not only introduces limitations—that is, the upper trolley track of the sintering machine must be installed first—but also easily damages existing tracks, posing a certain risk that the existing tracks may become unusable (requiring repair).

[0003] Therefore, developing an installation method for the sintering machine head wheel that is easy to install, requires no large lifting machinery, does not damage other tracks, and does not require the use of the upper trolley track of the sintering machine is of great practical significance. Summary of the Invention

[0004] Due to the aforementioned defects in the existing technology, the present invention provides an installation method for the sintering machine head wheel that is easy to install, requires no large lifting machinery for hoisting, does not damage other tracks, and does not require the use of the upper trolley track or other tracks of the sintering machine. This method overcomes the defects of the existing sintering machine head wheel installation, which requires the use of the upper trolley track or other tracks of the sintering machine, affects subsequent installation, and is extremely easy to damage the tracks.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for installing a sintering machine head wheel includes the following steps:

[0007] (1) Processing the movable frame of the sintering machine head wheel and the hoisting assembly, wherein the movable frame of the sintering machine head wheel is a frame structure and its hollow part allows the sintering machine head wheel to pass through in the vertical direction, and the bottom of the movable frame of the sintering machine head wheel is equipped with movable frame rollers that match the sintering machine track, and the hoisting assembly includes a hoisting beam and a crane fixedly installed on the hoisting beam, and the crane is equipped with a crane strap;

[0008] (2) Place the movable frame of the sintering machine head wheel on the sintering machine track, install a winch in front of the target installation position of the sintering machine head wheel, and fix the traction rope of the winch to the movable frame of the sintering machine head wheel;

[0009] (3) Connect the overhead crane to the hoisting assembly and use the crane straps to hold the head wheel of the sintering machine to be installed;

[0010] (4) After using the overhead crane to lift the sintering machine head wheel to be installed, move the movable frame of the sintering machine head wheel to the side of the sintering machine head wheel to be installed, place the lifting beam on the movable frame of the sintering machine head wheel and fix the two, and remove the connection between the overhead crane and the lifting assembly;

[0011] (5) Use a winch to pull the movable frame of the sintering machine head wheel to directly above the target installation position of the sintering machine head wheel;

[0012] (6) Use a crane to slowly lower the sintering machine head wheel to be installed, adjust the position of the sintering machine head wheel to be installed, and then install and fix the sintering machine head wheel to be installed.

[0013] The sintering machine head wheel installation method of the present invention can complete the installation of the sintering machine head wheel using the sintering machine track, without the risk of damaging other tracks. It does not require the prior installation of other auxiliary tracks such as the upper trolley track of the sintering machine, which is convenient for construction and operation. It does not require large lifting machinery (such as cranes) for hoisting. The tools used are simple in structure and easy to manufacture, with low cost and great application prospects.

[0014] As a preferred technical solution:

[0015] As described above, the sintering machine head wheel installation method includes a bottom frame and an upper fixed rod.

[0016] The bottom frame is a square frame structure, consisting of two bottom fixing rods I and two bottom fixing rods II. The two bottom fixing rods I are parallel to each other and are parallel to the arrangement direction of the sintering machine track. The two bottom fixing rods II are parallel to each other. Movable frame rollers are installed at the bottom of the bottom frame.

[0017] There are two upper fixing rods, which are parallel to each other and located directly above the bottom fixing rod I. The two ends of the upper fixing rods are fixedly connected to the two ends of the bottom fixing rod I through the two side fixing rods.

[0018] As described above, in the installation method of the sintering machine head wheel, the bottom fixing rod I, the upper fixing rod, and the two side fixing rods form an isosceles trapezoidal structure.

[0019] As described above, in the installation method of the sintering machine head wheel, two sets of wheel pairs are installed below the bottom frame. Each set of wheel pairs includes an axle and two movable frame rollers fixed at both ends of the axle.

[0020] As described above, in the installation method of the sintering machine head wheel, the bottom frame is provided with a plurality of wheel axle fixing hole groups for the wheel axle to pass through. All wheel axle fixing holes in a wheel axle fixing hole group are on the same straight line. The wheel axle passes through all wheel axle fixing holes in a wheel axle fixing hole group in sequence, and the wheel axle can rotate freely.

[0021] In the above-described method for installing the head wheel of a sintering machine, the traction rope is parallel to the track of the sintering machine.

[0022] In the above-described method for installing the sintering machine head wheel, the hoisting beam and the movable frame of the sintering machine head wheel are fixedly connected by bolts.

[0023] As described above, in the installation method of the sintering machine head wheel, there are two cranes, which are bolted to both ends of the lifting beam.

[0024] As described above, in the installation method of the sintering machine head wheel, the lifting beam is provided with a lifting hole on the side away from the crane installation. The crane hook can hook into the lifting hole of the lifting beam to realize the connection between the crane and the lifting component.

[0025] The above technical solution is only one feasible technical solution of the present invention. The scope of protection of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.
