Embodiment Construction

[0048] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0049] Such as Figure 1-8 Shown, a kind of elevator weight testing device comprises test trolley 1, control trolley 2, the water storage tank 3 of control trolley, the water tank 4 (being called for short test water tank) of test trolley, water pump 5, Load cell 6, display screen 7 and controller 8.

[0050] The trolley is driven by a motor and plastic tracks, and a load cell 6 is arranged on the trolley, which displays the weight of the vehicle on a display screen 7 near the handrail of the trolley. Through the keyboard on the controller 8, input the rated load capacity, loading factor, the total weight of the test trolley and the test water tank, automatically calculate the volume of water to be added, and transfer from the w...

Abstract

The invention discloses an elevator weight test device and method. The elevator weight test device comprises a controller and two trolleys with a same structure; one trolley is marked as a test trolley, and the other trolley is marked as a control trolley; each trolley is provided with a water tank, a water pump, a weighing sensor and a display screen; a water inlet of each water pump is communicated with the corresponding water tank; a water outlet of each water pump is provided with a flow sensor and is communicated with one end of a water pipe; the other end of the water pip can be communicated with the water tank of the other trolley; each weighing sensor is arranged at the bottom of the corresponding water tank; and the water pumps, the flow sensors, the weighing sensors and the display screens of the two trolleys are electrically connected with the controller. For the elevator weight test device, the test trolley is remotely controlled by the controller to perform a related weight test; a person does not need to enter an elevator car in the whole process to be prevented from being damaged by accidents of sudden shearing, elevator slip and the like of the elevator in the testprocess, and automatic uniform loading can be realized without needing that a person carries a weight back and forth, so that the test time is shortened, the labor intensity is lowered, and the efficiency and the safety of the weight test are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator weight test device and method. Background technique [0002] According to the provisions and requirements of relevant national laws and regulations, the installation and use of the elevator need to be inspected, and the elevator can only be put into use after passing the inspection. According to the "Elevator Supervision Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" (TSG T7001-2009), the balance coefficient test, speed limiter-safety gear linkage test, elevator speed test, and traction in the downward braking condition Inspection, static traction inspection, brake test and other inspection items all need to carry weights manually for load detection, which is labor-intensive and takes a long time for the test, especially for the 125% rated load downward braking test, which needs to be carried manually from outside the ele...
