Abstract

The utility model relates to a chain breakage protecting device, which comprises a drive sprocket wheel, a guide rail, a chain, a driven sprocket wheel, a power device and a control system, wherein the lower portion of the drive sprocket wheel is equipped with a detecting device, signals transmitted by the detecting device are connected with the control system, the detecting device comprises an inductive transducer and a mechanical stroke switch, should be arranged below the loose selvedge of the chain, and is about 1.8-2.5 cm away from the vertical surface of the drive sprocket wheel, and detecting signals are transmitted to the running control system. Chain breakage fault diagnosis is achieved by the detection of the detecting signals to a chain drive system, and a device is protected without being greatly damaged through cutting off a power source by the control system practically.

Description

A kind of chain breakage protection device
One, technical field
The utility model relates to chain gear, particularly relates to a kind of chain breakage protection device.
Two, background technology
At present; water treatment is with all adopting chain transmission mode as grid maker, chain type mud scraper in the mechanical equipment; a conveyer chain is set respectively in the equipment rack both sides; drive functional component and make gyroscopic movement; because the running environment of water processor machinery equipment is more abominable; be subjected to the long-term erosion of corrosive property gas, liquid; chain easily ruptures; particularly in one-sided chain fracture; can cause the functional component operation asynchronous; as untimely shutdown, will further cause the equipment large tracts of land and damage, even complete machine is scrapped.
This mechanical equipment generally all is provided with the setting of machine overload protection, but mechanical protection is based upon on the chain transmission system basis in working order, can not prevent the generation of chain rupture accident.
Three, summary of the invention
The purpose of this utility model is at above-mentioned the problems of the prior art, and a kind of chain breakage protection device is provided.
In order to reach described purpose, the invention provides a kind of chain breakage protection device, comprise drive sprocket, guide rail, chain, driven sprocket, engine installation, control system, arrangement for detecting is installed in the below of drive sprocket, and the signal of arrangement for detecting transmission links to each other with control system; Arrangement for detecting comprises inductosyn, mechanical stroke switch; Arrangement for detecting should be positioned at the below of chain slack list; Below two sprocket for main drive lateral surfaces arrangement for detecting is set, this installs apart from the about 1.8-2.5cm of the vertical surface of drive sprocket, and detection signal transfers to operation control system.
Beneficial effect is that by the detecting realization chain rupture Fault Diagnosis of detection signal to chain transmission system, by control system cut-out propulsion source, preventive device is not subjected to more macrolesion conscientiously.
Four, description of drawings
Fig. 1 is a kind of chain breakage protection device construction profile of the utility model scheme drawing.
Fig. 2 is a kind of chain breakage protection device Facad structure of the utility model scheme drawing.
Among the figure: 1. chain, 2. drive sprocket, 3. arrangement for detecting, 4. lower guide, 5. upper rall, 6. frame, 7. chain rupture point, 8. driven sprocket, 9. transmission shaft, 10. actuating device, 11. control system
Five, the specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in further detail:
Drive sprocket 2 is fixed on the transmission shaft 9 by pin key among Fig. 1,2, transmission shaft 9 is bearing on the frame 6 by bearing, rotation under actuating device 10 drives, and arrangement for detecting 3 is arranged on the frame 6, be positioned at the below in drive sprocket 2 outsides, apart from the drive sprocket 2 face 20mm that stands.Upper rall 5, lower guide 4, driven sprocket 8 are separately fixed on the frame 6, and driven sprocket 8 can turn round, and drive sprocket 2, lower guide 4, driven sprocket 8, upper rall 5 are formed the closed loop delivery system of chain 1.Arrangement for detecting 3 comprises inductosyn, mechanical stroke switch; Arrangement for detecting 3 should be positioned at the below of chain 1 slack list; Below sprocket for main drive 2 lateral surfaces arrangement for detecting 8 is set, this installs apart from the about 1.8-2.5cm of the vertical surface of drive sprocket 2.
In engineering is used; the chain rupture point 7 of grid maker generally be positioned at upper rall 5 certain a bit; in case fracture accident takes place in chain 1; because actuating device 10 is still in running; chain 1 begins sagging because of the lax drive sprocket 2 that breaks away from; reach the reconnaissance range of arrangement for detecting 3 when sag after; arrangement for detecting 3 sends the chain rupture signal; existing side by side soon, this signal imports control system 11 into; send halt instruction to actuating device 10 by control system 11; actuating device 10 shuts down, and sends alerting signal.

Claims (3)
