Lifting and descending device for electric energy meter checking device

Abstract

The invention relates to a lifting and descending device for an electric energy meter checking device. The lifting and descending device is characterized by comprising a fixed frame (1), wherein a movable plate (2) is arranged in the fixed frame (1); electric energy meters (21) are arranged on the movable plate (2); and a driving mechanism (3) which controls the movable plate (2) to lift and descend vertically is arranged between the fixed frame (1) and the movable plate (2). When an operator needs to assemble or disassemble a certain row of electric energy meters, a hand wheel is rotated to drive a pull wheel to rotate, and a steel wire rope which is embedded in the pull wheel drives the movable plate to move vertically through friction, so the electric energy meters are moved to the most appropriate place by the operator, a positioning bolt is inserted into a positioning strip through hole and used for fixing the movable plate, and the operator can safely, conveniently and effortlessly assemble and disassemble the electric energy meters. The lifting and descending device for the electric energy meter checking device has the advantages that the electric energy meter checking device is in accordance with a man-machine engineering principle; the operator can conveniently and effortlessly assemble and disassemble the electric energy meters; and compared with a fully-automatic lifting and descending device, the lifting and descending device is high in working efficiency, simple in structure and low in cost.

Description

【Technical field】 [0001] The invention relates to a lifting device, in particular to a lifting device used for a verification device of an electric energy meter. 【Background technique】 [0002] The traditional lifting device used for electric energy meter verification device has at least two rows of meter positions on the upper and lower sides, and each row has at least two meter positions on the electric energy meter, so as to realize multi-meter position verification, because each The meter position is fixedly installed, and the distance between the upper and lower rows is relatively large. The upper row is too high and the lower row is too low. It is not convenient for the staff to assemble and disassemble the meter and adjust the photoelectric head. The site area is large, and the staff has a long distance to walk back and forth; on the other hand, due to the different heights of the staff who assemble and disassemble the meter, the appropriate height for the staff to mo...

Problems solved by technology

[0002] The traditional lifting device used for electric energy meter verification device has at least two rows of meter positions on the upper and lower sides, and each row has at least two meter positions on the electric energy meter, so as to realize multi-meter position verification, because each The meter position is fixedly installed, and the distance between the upper and lower rows is relatively large. The upper row is too high and the lower row is too low. It is not convenient for the staff to assemble and disassemble the meter and adjust the photoelectric head. The site area is large, and the staff has a long distance to walk back and forth; on the other hand, due to the different heights of the staff who assemble and disassemble the meter, the appropriate height for the staff to mount the electric energy meter is different, and the working habits of different staff are different. The appropriate height of the meter is also different. Therefore, the staff of the traditional lifting device used for the calibration device of the electric energy meter are prone to fatigue. The electric energy meters in each row must be disassembled and calibrated at the same time, that is, when a certain row of electric energy meters is assembled and disassembled, the other row of electric energy meters cannot be calibrated, and the work efficiency is low. In order to improve the efficiency of electric energy meter inspection work and reduce the work Labor intensity of personnel, currently there are many kinds of automatic energy meter calibration devices or systems, but many kinds of fully automatic lifting device systems for energy meter calibration devices have a large station area and high cost, and can only calibrate electronic energy meters
