Description

It is a kind of for testing the test device of limiter of speed rope clamping block force value
Technical field
The present invention relates to a kind of elevator governor test equipments, and in particular to one kind is for testing limiter of speed rope clamping block force value Test device.
Background technique
Elevator governor is indispensable safety device in elevator device, and elevator governor can be matched with safety tongs As elevator overspeed or it is out of control when linked protector.The device that elevator governor is clamped as speed responsing and handling safety. And safety tongs is then with mechanical action by elevator mechanism of the stop on guide rail by force.When the overspeed switch of elevator governor is dynamic Make, cutting off elevator safety loop or control loop brakes electromagnetic brake power loss.Such as elevator continues downward Accelerating running, electricity Terraced limiter of speed will block wirerope, and wirerope lifts safety tongs linkage tie-bar, safety tongs is forced to act, and elevator is made by force It is parked on guide rail.Elevator governor is clamped wirerope by the effect of rope clamping block, and rope clamping block needs to have certain force value Wirerope can be clamped, if limiter of speed rope clamping block is inadequate to the force value of braking clamp, be easy to cause and be difficult in an emergency braking situation Elevator is braked, to cause safety accident.In production, the force value to limiter of speed rope clamping block is needed to detect, with Guarantee the quality of limiter of speed, but lack such test device at present, limiter of speed rope clamping block conveniently, accurately test.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems and provides a kind of for testing limiter of speed rope clamping block force value Test device.
The purpose of the present invention is achieved through the following technical solutions:
It is a kind of for testing the test device of limiter of speed rope clamping block force value, including rack, the support on rack top is set Frame, the support frame top lower end are arranged pressure sensor, set on the table top of the rack in the positive lower end of pressure sensor There is a lifting body, the pressure sensor connects display unit, and when work, measured workpiece is jacked up and is pressed on by lifting body Between lifting body and pressure sensor, the pressure sensor is by force value real-time Transmission to display unit.
Further, the display unit is liquid crystal display, is set to upper end at the top of support frame, can be in real time by pressure The pressure value of sensor is shown on a liquid crystal display, convenient for observing the force value of measured workpiece in time.
Further, the support frame includes the four columns of lower part and the Supporting cover set on four columns upper end Plate, the column are embedded in rack, and the support cover board is bolted on column, and four columns are embedded in rack It is interior, it firmly installs, support cover board is bolted on column, easy to disassemble, adjusting.
Further, the lifting body is electrohydraulic cylinder or lifting cylinder, passes through electrohydraulic cylinder or lifting air Cylinder can fast implement the jack-up of measured workpiece.
Further, the upper end of the lifting body is circular tube structure, is provided with a pair of of square on the round tube wall of the circular tube structure Circular tube structure is arranged in shape slot, lifting body upper end, can be convenient tested rope clamping block fixed placement, while can keep axial Alignment, so that when lifting body works, measured workpiece is pressed on pressure sensor;It is provided on the round tube wall of circular tube structure A pair of of rectangular shaped slot, convenient for picking and placing and adjusting measured workpiece.
Further, the pressure sensor lower end is in upper coarse and lower fine ladder circle column, and is equipped with four in lower part and is in Cross bolt, facilitates the upper end of measured workpiece to be clamped fixation, and bolt can guarantee that measured workpiece does not shift.
The present invention provides a kind of easy to operate, simple test device of structure for the force value tests of limiter of speed rope clamping block, The force value tests to rope clamping block can be fast implemented by the present apparatus, due to reflecting force value, detection essence in real time using pressure sensor Degree is high, can effectively ensure that the quality of limiter of speed, production efficiency and product quality are ensured.
