Technical Field
[0001] This utility model relates to the technical field of roadway support equipment, specifically to a rock retaining support adjustment device. Background Technology
[0002] Coal is the foundation of my country's social and national economic development, accounting for more than 70% of my country's energy consumption for a long time. During the mining process, in order to ensure construction safety, coal pillars are reserved between the transport roadway and the return airway in the mining area. The main function of the goaf-side roadway is to use technical means to re-support the original return roadway along the edge of the goaf, so that it can be used as the roadway (such as the return airway) of the next working face. This allows the recovery of the protective coal pillars left in traditional mining methods. The most common method is to rebuild the roadway support pillar, using flexible molds as concrete templates to pour a continuous concrete wall. When the concrete is completely solidified, it can support the original return roadway.
[0003] The retaining rock support group along the goaf is located behind the working face support. Generally, the posture of the two retaining rock support groups is adjusted by using each other as a reference. The traditional bottom adjustment device is located in the middle of the base and can only adjust the distance between the two supports by the thrust of the jack. This means that the distance between the two supports can only be increased, not decreased. At the same time, due to the thrust caused by the accumulation of gangue in the goaf, the retaining rock support group will continuously move towards the roadway side during the continuous forward movement. This can easily cause the retaining rock support group to tilt too much towards the roadway side or even slide horizontally, damaging the pushing mechanism or support device. Utility Model Content
[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide a rock retaining bracket adjustment device, which can promptly correct the gap and orientation between the two bracket bases and avoid damage to the equipment due to large-scale tilting.

Because two front ear plates are installed at the front end of the first support base and one rear ear plate is installed at the rear end; and front adjustment holes for connecting the first or second front adjustment seat and rear adjustment holes for installing the first or second rear adjustment seat are provided, changing the position of the front and rear adjustment holes can further expand the adjustment distance between the first and second support bases. Moreover, the connecting heads of the front and rear pull-to-move auxiliary cylinders are hinged and can rotate at a certain angle. During the movement, even if a slight offset occurs, there will be no interference. Furthermore, both the front and rear pull-to-move auxiliary cylinders have a large thrust, which can provide auxiliary thrust for the movement of the support base. Attached Figure Description
