Description

Technical Field

[0001] The invention belongs to the technical field of gate installation, and relates to a narrow space gate installation, in particular to a narrow space gate installation method and installation tooling. Background Art

[0002] A gate usually refers to a device used to control the flow of water, air or other materials. It can be used in water conservancy projects, sewage treatment, power plants and other places to adjust water levels, flow or prevent backflow. There are many types of gates, such as gate plates, gate valves, gates, etc. Different types of gates are suitable for different scenarios and needs. Gate installation is an important task in the fields of water conservancy projects, sewage treatment, channel management, etc.

[0003] After searching, it is found that a Chinese patent document discloses a gate hoisting construction method for narrow working space [Application number: CN201910605597.5; Publication number: CN110304588B]. For gate installation in narrow working space, the upper cavity of the gate is used as the space for rotation construction. The first and second segments of the gate are hoisted first, and the short sides are used for hoisting. After the upper cavity is rotated, it is placed upstream or downstream of the gate slot, and the installation space of the gate slot is reserved. Then, the third segment is hoisted on the short side, and after the third segment is rotated in the upper cavity, it is lowered to the gate slot, and then the second segment and the first segment are hoisted in sequence, and placed in the gate slot in sequence.

[0004] The assembly of the segmented gate disclosed in the patent can make full use of the narrow space above the gate slot to improve work efficiency. However, it is difficult to transport the gate in a narrow space. In particular, the gate slot position is narrow during the transportation of the segmented gate, which may result in insufficient transportation width. In addition, the position of the gate needs to be adjusted after transportation, so the gate needs to be rotated. However, the operation is not convenient in a small space, so the above problems need to be solved. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a narrow space gate installation method and installation tooling. The technical problem to be solved by the invention is: how to achieve efficient grinding and mixing of ground film masterbatch by a film blowing machine and carry out quantitative and precise delivery.
