Vertical shaft construction stepping template system, hydraulic control system thereof and pipeline collecting/mounting method

Abstract

The invention relates to a vertical shaft construction stepping template system, a hydraulic control system thereof and a pipeline collecting / mounting method. The vertical shaft construction stepping template system comprises a hydraulic station, an upper gripper shoe loop, a lower gripper shoe loop, a stepping loop and a template loop; the upper gripper shoe loop comprises a pilot loop I and a main oil loop I; the pilot loop I comprises an upper gripper shoe operating rod, and the main oil loop I comprises an upper gripper shoe oil cylinder set and a first energy accumulator; the lower gripper shoe loop comprises a pilot loop II and a main oil loop II; the pilot loop II comprises a lower gripper operating lever; the main oil loop II comprises a lower gripper shoe oil cylinder set and a second energy accumulator; sequence valves are arranged between the upper gripper operating lever and a main valve A and between the lower gripper operating lever and a main valve B; and one-way valve sets are arranged between the upper gripper shoe oil cylinder set and the first energy accumulator and between the lower gripper shoe oil cylinder set and the second energy accumulator correspondingly. According to the vertical shaft construction stepping template system, the distance between the gripper shoe and a template can be increased, a hydraulic pipeline is protected, the manual labor amount is reduced, and the safety of the construction process is improved.

Description

technical field [0001] The invention relates to the technical field of shaft construction in mines, and in particular to a stepping formwork system for shaft construction, a hydraulic control system, and a pipeline collection / installation method. Background technique [0002] Vertical (vertical) shaft is a main development method of mine mining. In recent years, new mines account for about 45% of the total number of mines. With the construction of new districts and the deep development of mining, the proportion of vertical shaft development will increase. The construction technology of shaft shaft engineering is complicated, the working place is narrow, the working environment is harsh, and it is often subject to changes in geological conditions. Therefore, although its engineering volume only accounts for about 6% of the total mine shaft engineering volume, its construction period usually accounts for more than 40% of the total mine construction period. [0003] There are...

Problems solved by technology

[0003] There are still some deficiencies in the current related schemes: the integral hydraulic formwork of the casing wall of the vertical shaft (CN103850686A) takes up a large amount of equipment materials such as car stabilizers and steel wire ropes, and cannot adapt to deep well mining; the integral metal formwork (CN107083976A) only The movement can be realized through longitudinal support and guidance, but the circumferential movement of the upper and lower formwork can not be avoided; the distance between the support shoes and the formwork of the vertical shaft construction based on hydraulic drive (CN110863831A) is too close and does not take into account the impact on the hydraulic pipeline when blasting out. protection of
