Abstract

The invention provides a locking tool for a construction lift landing door. The locking tool comprises a locking rod and a base, the locking rod is fixed to the base, the base comprises a supporting plate, a first mounting seat, a second mounting seat and a third mounting seat, the first mounting seat is located under the locking rod, the second mounting seat is fixed to one side of the first mounting seat, the third mounting seat is fixed to one side of the second mounting seat, and two locking pins are fixed to the locking rod. The locking tool for the construction lift landing door has thefollowing advantages that adjusting is conducted according to the need, using is convenient, the structure is more firm, the structure is simple, demounting and mounting are convenient, and the service life is longer.

Description

Technical field [0001] The invention belongs to the field of mechanical tools, and in particular relates to a locking tool for a floor door of a construction elevator. Background technique [0002] The linear switch valve is a mechanical component that is opened by a hydraulic cylinder and closed by a compression spring after the pressure is released from the hydraulic cylinder. It is widely used in the process of underwater oil and gas exploitation. When the opening device of the linear switch valve fails, the equipment cannot operate normally, which directly affects the oil production process, and even causes huge economic losses. In addition, the underwater situation is complicated, the operation and maintenance are difficult, the maintenance time is long, and the cost is high. [0003] Therefore, there is an urgent need to develop an effective auxiliary tool that can maintain the normal operation of the linear switch valve when the opening device of the linear switch valve its...
