Description
Technical field
The utility model relates to a kind of security warning, fender guard, specifically, relates to the two-way accident pull switch of a kind of band conveyor.
Background technology
At steel plant, colliery, thermal powerplant, cement mill, chemical plant, harbour etc., main use band conveyor convey materials, for ensureing the safe operation of band conveyor, generally the two-way accident pull switch of band conveyor can be set in the both sides of band conveyor.When finding that belt operation jeopardizes personal device security phenomenon, pull stay cord immediately, stay cord drives the action of two-way accident pull switch, makes band conveyor out of service.
Mainly there is following defect in existing band conveyor two-way accident pull switch: 1, material is mostly ironcasting or aluminum casting, and oxide etch is fast; 2, the check screw of installation chassis is common galvanized screw, easily serious corrosion occurs and causes extremely difficult dismounting; 3, most of two-way accident pull switch alarm free instruction, the two-way accident pull switch of the tape light having indivedual producer to provide is also just with a kind of very little red light instruction, and naked eyes are difficult to differentiate; 4, the mode of connection of stay cord is extraction, must carry out cable junction like this, easily intake, cause misoperation frequent outside switch.
Utility model content
The purpose of this utility model is, provides a kind of band conveyor two-way accident pull switch, to solve above-mentioned technical matters.
For solving the problem, the technical scheme that the utility model adopts is:
The two-way accident pull switch of a kind of band conveyor, comprise housing, the bottom of described housing is provided with installation chassis, and the two ends of described installation chassis offer mounting hole respectively; It is characterized in that: the bottom of described housing cavity is provided with bi-directional expansion transverse axis, the two ends of described bi-directional expansion transverse axis are run through and are movably arranged on the left and right sidewall of housing; The middle part of described bi-directional expansion transverse axis is installed with touches block, described in touch block the left and right sides be respectively equipped with left side spring, right side spring, described left side spring, right side spring are all enclosed within bi-directional expansion transverse axis; The described top touching block is symmetrically arranged with two micro-switchs, is left side micro-switch, right side micro-switch respectively; The top of described housing cavity is provided with relay, and described relay is provided with connection terminal.
Say further, the top of described housing right side wall is installed with combined aural and visual alarm.
Again furtherly, be also provided with relay reset switch in described housing cavity, described relay reset switch is arranged on the left side wall of housing.
Beneficial effect: compared with prior art, the utility model long service life, easy to maintenance, operation is simple, all wiring are all in switch case, cable junction outside switch can be avoided, stop because of the moisture-induced misoperation of cable junction, also facilitate service personnel to carry out line fault investigation simultaneously, facilitate the replacing of service personnel switch to install.And the utility model has sound and light of alarm, can the discovery trouble point of simple, intuitive, convenient maintenance, operations staff process in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, the two-way accident pull switch of band conveyor described in the utility model, comprises the housing 1 adopting nylon to add fire-proofing material to process.The bottom of described housing 1 is provided with installation chassis 7, and the two ends of described installation chassis 7 offer mounting hole respectively.
The bottom of described housing 1 inner chamber is provided with bi-directional expansion transverse axis 6, and the two ends of described bi-directional expansion transverse axis 6 are run through and are movably arranged on the left and right sidewall of housing 1.The middle part of described bi-directional expansion transverse axis 6 is installed with touches block 9, described in touch block 9 the left and right sides be respectively equipped with left side spring 8, right side spring 10, described left side spring 8, right side spring 10 are all enclosed within bi-directional expansion transverse axis 6.The described top touching block 9 is symmetrically arranged with two micro-switchs, is left side micro-switch 5, right side micro-switch 11 respectively.The top of described housing 1 inner chamber is provided with relay 2, and described relay 2 is provided with connection terminal.Described relay 2 adopts low-voltage direct 24V power supply, and safety performance is high.The top of described housing 1 right side wall is installed with combined aural and visual alarm 3.Also be provided with relay reset switch 4 in described housing 1 inner chamber, described relay reset switch 4 is arranged on the left side wall of housing 1.
Principle of work of the present utility model is summarized as follows: the two ends of bi-directional expansion transverse axis 6 connect stay cord respectively; When belt attendant or field service personnel find belt error state, pull the stay cord arranged along belt direction; Stay cord drives bi-directional expansion transverse axis 6 to produce displacement, the block 9 that touches be fixed in the middle of bi-directional expansion transverse axis 6 touches left side micro-switch 5 or right side micro-switch 11, left side micro-switch 5 or right side micro-switch 11 action power transmission are to relay 2, relay 2 action power transmission is to the tripping relay in belt shipper case, and band conveyor is out of service; Meanwhile, combined aural and visual alarm 3 luminous alarm, extremely, attendant or service personnel check on-the-spot belt for prompting attendant or service personnel scene, process abnormal condition; After being disposed, press the button of relay reset switch 4, band conveyor recovers normal and runs.
