The main disadvantages of this method are: first, the construction cost of the steel beam is high and the construction period is long; second, there is no suitable longitudinal steel beam in some shafts or it is not suitable to install the longitudinal steel beam, so the cable fixing cannot be implemented; Third, because the position of the steel beam is fixed, the position of the cable cannot be adjusted. There are special requirements for the distance between the cable and the container (such as a cage) or the distance between the cable and the container (such as a cage) cannot be fixed when the distance needs to be adjusted.

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and examples.
[0017] The steps of the present invention are as follows: figure 1 An upper beam 2 and a lower beam 6 are respectively fixed at the appropriate positions of the upper end (generally at the upper end of the shaft) and the lower end of the cable laying in the shaft 1, and the bearing strength of the upper beam 2 and the lower beam 6 is determined by the weight of the cable and the depth of the well.
[0018] Fix the upper ends of the two steel wire ropes 4 with appropriate thickness on the upper beam 2 respectively, and use a guide chain with a dynamometer to tighten the two steel wire ropes 4 so that the tension of the two steel wire ropes is the same, and then the two steel wire ropes The lower end is fixed to the lower beam 6 through the UT clamp 5.
[0019] On the steel wire rope 4, a cable connection mechanism 3 for cable laying is fixedly arranged eve...

The present invention is a flexible fixing method for special-demand cables in shafts. 1) Fix an upper beam and a lower beam at the upper end and lower end of cable laying in the shaft; 2) Fix the upper ends of two steel wire ropes on the upper beam respectively and use a guide chain with a dynamometer to tighten the two steel wire ropes so that the tension of the two steel wire ropes is the same, and then fix the lower ends of the two steel wire ropes to the lower beam; 3). A cable connection mechanism for cable laying and fixing is provided at a distance, so that the cable is laid in a straight line parallel to the axis of the shaft in the shaft. In a vertical shaft without longitudinal steel beams, the cable can be laid in a straight line parallel to the axis of the shaft in the shaft, the plane of the cable is parallel to the facade of the container, the horizontal spacing distance can be adjusted, and the construction cost is low.
Description
technical field [0001] The invention relates to a cable fixing method applied in a shaft. Background technique [0002] With the development of control technology, the functions, shapes and materials of cables in mine shaft shafts are various, so the fixing methods of cables are also varied. The traditional shaft cable fixing method is to use the steel beams arranged longitudinally (the direction is consistent with the shaft) in the shaft, and fix the cables on the steel beams at certain distances with the help of suitable cable clips. The main disadvantages of this method are: first, the construction cost of steel beams is high and the construction period is long; second, there are no suitable longitudinal steel beams in some shafts or it is not suitable to install longitudinal steel beams, so cable fixing cannot be implemented; Third, because the position of the steel beam is fixed, the position of the cable cannot be adjusted. There are special requirements for the dista...
