Problems solved by technology
[0005] The purpose of the present invention is to solve the above-mentioned problem that the middle part of the inside of the flexible water tank does not have the operating space for the locking of the connecting rod group, rationally utilize the existing structure of the flexible water tank, and design a limiting device that can be operated at the remote end Realize the locking of the middle connecting rod group inside the two tanks
With the structure that the pushing device extends to the edge of the flexible water tank, the locking and unlocking of the middle link group 32 inside the flexible water tank can be realized by operating the limit device 1 at the far end, which solves the problem of locking the middle part of the water tank. The problem of tight and no operating space

The invention discloses a flexible water tank locking device, belonging to the technical field of oil and natural gas fracturing stimulation equipment. The locking device comprises a foldable hollow support, wherein the foldable hollow support comprises at least two frames and a linkage set. The linkage set comprises two linkages which are hinged together, and the two linkages are respectively hinged onto the adjacent two frames. The other ends of the linkages are sliding ends, and the sliding ends of the linkages are arranged on the adjacent frames in a sliding mode. A chute is arranged in at least one frame, and the chute is formed in the inner part of the frame. The sliding ends of the linkages are arranged in the chute, and a limiting device is installed on the frame. The limiting device can limit the position of the sliding ends of the linkages and extends to the edge of a flexible water tank. The limiting device can be operated at the end part of the water tank, the locking and unlocking of the linkages is realized, and the problem that the middle locking position of the water tank does not have an operating space is solved.
Description
technical field [0001] The invention mainly relates to a flexible water tank locking device, which is used for oil and natural gas fracturing stimulation construction, and belongs to the technical field of manufacturing oil and natural gas fracturing stimulation equipment. Background technique [0002] In the process of fracturing construction, thousands of cubic meters of fracturing water are needed. The number of traditional water tanks required is large and the floor area is large. The use of flexible water tanks can greatly reduce the number of water tanks and thus reduce the land occupation. area. [0003] The applicant's early utility model patent - Chinese patent specification CN 202609381 U discloses a liquid container, a liquid container device and a liquid container assembly. The utility model mainly relates to a liquid container, including a foldable hollow bracket and a The soft bag used for containing liquid in the bracket also relates to a liquid container dev...
