Description

A tooling platform for assembling the upper shaft assembly of a flotation machine

technical field

The utility model relates to the technical field of flotation machine maintenance equipment, in particular to a tooling platform for assembling an upper shaft assembly of a flotation machine.

Background technique

KYF/XCF flotation machine is the most important equipment for beneficiation reverse flotation process. The installed capacity is large and the maintenance frequency is high. The upper shaft assembly is composed of two parts, the bearing box of the flotation machine and the upper shaft. First assemble the upper shaft bearing and seal, and after the assembly is completed, stand upright on the ground. Lift the bearing box and assemble the upper shaft and assemble it to the bearing hole of the box. Because the bearing hole and the bearing outer ring are excessively matched, the upper shaft, the bearing outer ring and the bearing box must be kept horizontal. If one of the three levels fails to meet the requirements, the assembly cannot be completed. Because the bearing box is large and is in a suspended state, during the assembly process, the maintenance personnel cannot directly adjust the level of the upper shaft and the outer ring of the bearing, but can only lift the bearing box to the ground. After the adjustment, try again. This assembly operation requires repeated adjustment and hoisting to complete the assembly, which is time-consuming and labor-intensive. In addition, during the assembly process, maintenance personnel need to observe the assembly situation, and there is a safety risk when it is close to the lifting bearing box.

Utility model content

In view of the above technical problems, the utility model provides a tooling platform for assembling the upper shaft assembly of the flotation machine, which can avoid the current assembly of the upper shaft assembly of the flotation machine, which is often continuously hoisted by hoisting equipment, and finally completes the assembly. The working time is long and the labor intensity is high. In addition, during the assembly process, the maintenance personnel need to observe the assembly situation, and there is a safety risk when it is close to the lifting bearing box.

In order to achieve the above object, the technical scheme of the present utility model is as follows:

A tooling platform for assembling an upper shaft assembly of a flotation machine includes a support frame, a staircase is arranged on one side of the support frame, and a support plate capable of vertically fixing a bearing box is arranged on the upper part of the support frame. The bearing box is placed vertically on the support plate on which the bearing box is vertically fixed, and the upper bearing is hoisted on the bearing box.

A guardrail is arranged around the support plate capable of vertically fixing the bearing box.

The support plate capable of vertically fixing the bearing box is provided with a flat plate structure with a square hole that can be vertically inserted into the bearing box as the center, and the lower side of the square hole is fixed to the inner side of the support frame through a number of diagonal ties.

The beneficial effects of the present utility model are as follows: the utility model inverts the bearing box through the lifting device and then vertically places the bearing box on the support plate that can fix the bearing box vertically, and then lifts the upper bearing into the bearing box through the lifting device. By standing on the support plate that can fix the bearing box vertically, the hoisting process is fine-tuned, and the assembly is finally completed. The support plate that is fixed vertically is a flat plate structure with a square hole that can be vertically put into the bearing box as the center. For the support function, in order to improve the support strength, the lower side of the square hole is fixed to the inner side of the support frame through a number of diagonal ties.

Figure 3 is a state diagram of the utility model in use.

Among them, 1-support frame, 2-guardrail, 3-stair.

Detailed ways

As shown in Figures 1 to 3, a tooling platform for assembling the upper shaft assembly of the flotation machine includes a support frame 1, a staircase 3 is arranged on one side of the support frame 1, and the upper part of the support frame 1 is provided with a bearing box that can vertically The fixed support plate can place the bearing box vertically on the support plate that can fix the bearing box vertically. The straight-fixed support plate has a flat plate structure with a square hole in the center that can be vertically placed into the bearing box, and the lower side of the square hole is fixed to the inner side of the support frame 1 through a number of diagonal ties.

When the utility model is in use, the operator makes the bearing box upside down through the hoisting equipment, and lifts it into the square hole. After the adjustment position is placed stably, the support plate on the outside of the bearing box and the square hole are fixed to each other with bolts, and the upper shaft is installed with a movable seal The gland and bearing B are assembled upside down and the bearing box are assembled. During the process, the maintenance personnel stand on the channel of the platform and adjust the position of the bearing B and the upper shaft at any time. The bearing B can be loaded into the bearing box boring hole in one lifting. After completion, hoist the assembly to the ground, and then install the bearing A. The assembly process saves time and effort. When the upper shaft is assembled with the bearing box, the lifted upper shaft has been inserted into the bearing box. The safety of the maintenance personnel can be ensured, and the overall occupied space of the utility model is small; the assembly time of the assembly is reduced from the original 8 hours to the current 2 hours, the maintenance efficiency is greatly improved, the maintenance operation conditions are improved, and the maintenance personnel are essentially guaranteed. The safety of the assembly process of the assembly.
