Description
Technical field
The invention belongs to elevator detection technique field, is related to a kind of detection device of improved elevator sky rail.
Background technology
Elevator can be generally divided into two kinds：A kind of is the vertical conveyor using motor as power, equipped with box-like gondola, is used
Multiply people or carrying cargo in tier building；Another is step, and step plate continuously runs on crawler belt, is commonly called as helping automatically
Ladder or moving sidewalk, serve the fixed type lifting equipment of regulation floor.Vertical lift elevator has a carriage, operates in
At least two row it is vertical or between rigid guideway of the inclination angle less than 15 °.Car size and structure type come in and go out easy to passenger or
Handling goods.No matter traditionally its type of drive, the general name using elevator as vertical transportation means of transport in building.Electricity
Ladder can divide slower elevators (below 1 meter per second), express lift (1-2 meter per seconds) and express elevator (more than 2 meter per seconds) by speed.
Cage guide, is important component in running process of elevator, it is divided into car guide rail and counter weight guide track, and guide rail exists
While playing the guiding role, carriage is born, impact force during elevator brake, is divided into T-shaped from cross sectional shape, L-shaped and three kinds hollow
Form.And in actual manufacturing process, technical staff is generally by cross sectional shape is T-shaped and L-shaped is known as real rail, by cross sectional shape
It is known as empty rail in hollow shape.Real rail and empty rail are the important component of cage guide, to maintain the stable operation of elevator.
Elevator operationally its load-carrying and position of centre of gravity can with crowd number and crowd erect-position situation always
Changing, elevator sky rail must be able to bear operation of the elevator under various load conditions.In order to ensure the security of elevator sky rail
Can, it is necessary to elevator sky rail is detected, to examine its quality, the detection to elevator sky rail at present mainly by structural strength come
Carry out, there is no the detection device of simulating actual conditions, therefore detection data are more single, and reference value is not high.
The content of the invention
The purpose of the present invention is for existing technology, there are the above problem, it is proposed that a kind of inspection of improved elevator sky rail
Survey device, present invention solves the technical problem that be can simulant elevator practical operation situation detect elevator sky rail.
The purpose of the present invention can be realized by following technical proposal：
A kind of detection device of improved elevator sky rail, including testing stand and slide plate, it is characterised in that on the testing stand
