Abstract
The invention discloses a kind of screw retention detectors, including detection circuit, several measure loops are parallel in the detection circuit, the thin film switch and wireless launcher of series connection are respectively equipped in each measure loop, the thin film switch is located at the gasket of bolt, and crane master switch is equipped with the control device for the signal for receiving the wireless launcher transmitting.The advantage of the invention is that：The tightness of each standard knot fixing bolt can be monitored automatically, master switch and the alarm of crane are disconnected in bolt looseness, and cage is avoided more to save manpower into unsteady guide rail bracket section.
Description
Technical field
The present invention relates to a kind of bolt detection device more particularly to a kind of screw retention detectors.
Background technology
5.6.1 regulations should have effective measures in existing elevator standard GB26557, detect unsteady guide rail bracket
Section, and can prevent cage into the guide rail bracket section or can guarantee cage without departing from firm guide rail bracket section；5.4.1.3 regulation is led
Rail gantry is directly connected to keep firm.Connection in the various specifications of derrick crane, standard all with standard knot should consolidate.It is logical
Often, the standard knot fixing bolt of elevator or derrick crane can only be checked after installing for the first time by artificial method,
Major way is：Macroscopic appearance inspection, sound test, are extremely inspected by random samples individually using torque spanner.Every two feast-brand mark of derrick crane is accurate
It is bolted between section using 4 to 8, quantity is more, erection is high, checks that bolt tightness labor intensive is big, and can not protect
Demonstrate,prove result.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of master switch that crane can be disconnected in bolt looseness
Screw retention detector.
The present invention is to solve above-mentioned technical problem by the following technical programs：A kind of screw retention detector, including inspection
Slowdown monitoring circuit (1) is parallel with several measure loops in the detection circuit (1), the film of series connection is respectively equipped in each measure loop
Switch (2) and wireless launcher (3), the thin film switch (2) are located at the gasket of bolt, and crane master switch is equipped with and connects
Receive the control device of the signal of the wireless launcher (3) transmitting.
Technical solution as an optimization, the power supply of the detection circuit (1) use DC power supply.
Technical solution as an optimization, the thin film switch (2) are circular ring shape.
Technical solution as an optimization, which, which further includes, receives the signal that the wireless launcher (3) emits
Warning device.
Technical solution as an optimization, the detector further include reception of wireless signals end (4) and display end (5), the nothing
Line signal receiving end (4) receives the signal of wireless launcher (3) transmitting, and the reception of wireless signals end (4) connects institute
State display end (5).
The advantage of the invention is that：The tightness of each standard knot fixing bolt can be monitored automatically, in bolt looseness
The master switch of crane and alarm are disconnected, cage is avoided more to save manpower into unsteady guide rail bracket section.
Description of the drawings
Fig. 1 is the structure diagram of screw retention detector of the present invention.
Specific embodiment
As shown in Figure 1, a kind of screw retention detector, including detection circuit 1, thin film switch 2, wireless launcher 3, nothing
Line signal receiving end 4, display end 5, crane master switch control device and warning device.
Several measure loops are parallel in detection circuit 1, the thin film switch 2 and nothing of series connection are respectively equipped in each measure loop
Line emitter 3, thin film switch 2 are located at the gasket of bolt, crane master switch control device, warning device and wireless signal
Receiving terminal 4 receives the signal of the transmitting of wireless launcher 3 respectively, and reception of wireless signals end 4 connects display end 5.
The power supply of detection circuit 1 uses DC power supply, and thin film switch 2 is circular ring shape.
It is fitted closely using the thin film switch 2 and standard knot fixing bolt of circular ring shape, when bolt normally compresses, film is opened
It closes 2 to be pressurized, measure loop is in "on" position；When bolt looseness, 2 stress of thin film switch variation, measure loop is in
Off-position.
3 dead electricity of wireless launcher when measure loop is in off-position, controls crane master switch control device
Heavy-duty machine master switch is disconnected and alarmed, and cage is avoided to enter unsteady guide rail bracket section.
Each thin film switch 2 controls the power on/off of a wireless launcher 3, and each wireless launcher 3 is compiled
Number and distinguish wireless signal, receive all wireless signals at reception of wireless signals end 4, and distinguish and be shown on display end 5, appoint
One wireless signal of meaning has break-make situation, and display end 5 can distinguish display.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should all be included in the protection scope of the present invention.
