Description

Pillar enclosure supporting device Technical Field The utility model belongs to the technical field of foundation engineering construction equipment, and particularly relates to a pillar enclosure supporting device. Background In the mine exploitation construction process, the mining method determines the stoping process, material equipment, labor productivity, comprehensive utilization degree of resources and the like. After the whole ore block is completely extracted, performing primary cemented filling to form an artificial ore pillar, after the cemented body reaches the maintenance time, returning the artificial ore pillar to a mining room by the same method, and performing primary non-cemented filling after the ore room is completely extracted. In the existing open stope subsequent filling mining process of the ore pillar, the ore pillar is alternately divided into an ore room and the ore pillar, the ore pillar is used for supporting and controlling the ground pressure, and ores and surrounding rocks are all required to be stable, so that the ore pillar is required to be subjected to enclosing and reinforcing treatment, and the stability of the ore pillar is improved. However, the topography and the top of the periphery of the pillar are uneven, so that the enclosure devices cannot be stably fixed, and meanwhile, the enclosure devices are required to be stably and flexibly connected and reinforced. Disclosure of utility model Aiming at the problems, the utility model provides the pillar enclosure supporting device which is used for realizing the height adjustment of pillar enclosure supporting pieces and improving the connection strength between the supporting pieces at the same time so as to improve the adaptability and the firmness of the whole device. In order to achieve the above purpose, the utility model adopts the following technical scheme: A pillar enclosure supporting device comprises base pillars which are uniformly arranged at the lower part of the outer side of a pillar at intervals, a track is vertically arranged on the side edge of the base pillar, a top pillar which can be adjusted and moved up and down is arranged in the track, a fastening piece with the front end fixed in the pillar is arranged between the base pillar and the top pillar, an enclosure belt is arranged between the base pillars and outside the pillar, the enclosure belt comprises a fastening belt, and two ends of the fastening belt are respectively connected with the fastening pieces on two adjacent base pillars. As a further improvement of the scheme, the number of the base columns is four, connecting arms are arranged between two symmetrical pairs of base columns, and the enclosure belt is arranged between the base columns which are not connected through the connecting arms. As a further improvement of the above scheme, the enclosure further comprises a base protection belt, and the base protection belts are fixedly connected with the bottoms of two adjacent base posts respectively. As a further improvement of the scheme, the top of the jacking column is provided with a jacking block, the upper surface of the jacking block is a contact surface, and the cross section profile of the contact surface is zigzag. As a further improvement of the scheme, the jack post is provided with a fastening groove at a fastening piece, and the side face of the jack post is provided with a warning lamp. As a further improvement of the scheme, the base is arranged at the bottom of the base column, and the base is provided with a column foot for auxiliary support in an outward extending mode. As a further improvement of the scheme, the base column is provided with a through groove in the track, the fastening piece is fixedly connected with the bottom end of the top column, the front end of the fastening piece penetrates through the through groove and is fixed on the ore column, and the fastening piece is a fastening anchor. Compared with the prior art, the utility model has the beneficial effects that: 1. Through the track sliding fit of base post and jack-up post, realize the adaptability support of the not co-altitude of ore pillar side, join in marriage simultaneously and further connect between the guard band to the base post and consolidate, let the base post more stable and closely support in the ore pillar outside. 2. The zigzag contact surface can effectively improve the bonding strength of the top column and the top surface of the ore column, and the fastener with the fastening anchor can more conveniently adjust the relative displacement distance of the base column and the top column. 3. The nameplate and the warning lamp can help staff to know information of the current pillar enclosing and supporting device, the setting of the column foot can further improve the stability degree of the base column, and the front end of the column foot can also help staff to divide the pillar enclosing range.
