Elevator load testing machine

Abstract

The invention discloses an elevator load testing machine and relates to the technical field of elevator detection. The problems that time and labor are wasted and labor cost is high when a load test is conducted on an elevator are solved. The elevator load testing machine is technically characterized in that the elevator load testing machine comprises a first water storage device, an electromagnetic valve, a water pipe, a flow meter, a water pump, a second water storage device and a microcomputer controller, the first water storage device, the electromagnetic valve, the flow meter, the water pump and the second water storage device are sequentially connected through the water pipe, and the electromagnetic valve, the flow meter and the water pump are connected with the microcomputer controller through leads; and water is accurately metered through a metering control device based on the single-chip microcomputer technology, the elevator load testing machine is equivalent to a traditionalstandard substance weight to be used for various load tests of the elevator, computer calculation control replaces manual calculation carrying, the problems of reworking and time consumption caused by errors generated in the weight carrying process are thoroughly solved, and high improvement of load test work efficiency and great reduction of physical labor intensity are achieved.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to an elevator load testing machine. Background technique [0002] With the rapid development of the economy, elevators have become a special equipment closely related to people's lives. It can be seen everywhere. The safety of elevators has increasingly become the focus of people's attention. For this reason, our country has issued a series of national standards and technical specifications The design, manufacture, installation, inspection, and use of the elevator have made detailed regulations and requirements. The elevator must pass the self-inspection of the installation unit before it can apply for supervision and inspection to the inspection agency. supervision and inspection projects. [0003] Elevator load test is the most important item related to elevator safety, and it is also an item that must be inspected. Compared with other safety device inspections, load ...
