Description
Technical field
The utility model relates to Construction Safety technical field, specifically, relates to a kind of instable slope autoalarm.
Background technology
In each high earth and rockfill dam filling construction process, be all faced with dam abutment excavation, each import slope excavating, building stones field slope excavating and borrow pit slope excavating.Due to the trend of each excavation slope rock fracture and the difference of earth material character, in slope excavating process, easily form instable slope.The development trend of instable slope, in instable slope construction processing process, must be understood in time in scene, could in guaranteeing construction safety, reach the object of quick early warning.
Deformation characteristics (creep--changing of the relative positions--collapses) after forming in conjunction with instable slope, must lay warning system in work progress, just can make workmen and timely, orderly the withdrawing of equipment in instable slope region.
Conventional report to the police supervisoryly for manually instable slope being carried out to the other station of safety and patrol and construction time, find that slope displacement adopts the staff on intercom notice warning horn side to sound the alarm immediately when changing greatly or collapsing, reach the object of warning.Adopt conventional alarm method pre-warning time longer, be unfavorable for reaching the object of quick hedging, and easily off one's guard after the long-term spiritual high concentration of tour supervisor.
Utility model content
The purpose of this utility model is to provide a kind of instable slope autoalarm, after reaching instable slope distortion, warns fast.
The technical scheme that the utility model adopts is: a kind of instable slope autoalarm, comprise steel pipe, and one end sealing of steel pipe, the other end arranges wire rope chute, and side has slide block chute; Steel duct is provided with tension spring, and one end of tension spring is connected to the blind end of steel pipe, and the other end is connected to the bottom of slide block; The top of slide block is connected to wire rope; Wire rope is drawn through the wire rope chute of steel pipe, is connected with joint bar; Steel pipe arranged outside has upper stroke switch and lower stroke switch, and upper stroke switch and lower stroke switch are connected respectively to the auxiliary contact of contactor; On slide block, be provided with teat, teat stretches out from slide block chute, between upper stroke switch and lower stroke switch; The main contacts of contactor and power supply, warning horn connect and compose alarm circuit successively.
As further improvement: the wire rope of described autoalarm forms by two sections, the middle wire clips that adopts connects.
When the utility model can meet instable slope and deforms, the quick warning of the very first time, can be widely used in all kinds of unsettled side slopes.Simple in structure, easy processing, safe and reliable, highly sensitive, has alleviated safety and patrol personnel's pressure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-joint bar; 2-wire rope; 3-wire clips; 4-steel pipe; 5-fixes joint bar; 6-tension spring; 7-slide block; 8-lower stroke switch; 9-upper stroke switch; 10-electric wire; 11-contactor; 12-power supply; 13-warning horn.
Embodiment
Embodiment: as shown in Figure 1, this instable slope autoalarm, comprises steel pipe 4, one end sealing of steel pipe 4, the other end arranges wire rope chute, and side has slide block chute; Steel pipe 4 inside are provided with tension spring 6, and one end of tension spring 6 is connected to the blind end of steel pipe 4, and the other end is connected to the bottom of slide block 7; The top of slide block 7 is connected to wire rope 2; Wire rope 2 is drawn through the wire rope chute of steel pipe 4, is connected with joint bar 1; Steel pipe 4 arranged outside have upper stroke switch 9 and lower stroke switch 8, and upper stroke switch 9 and lower stroke switch 8 are connected respectively to the auxiliary contact of contactor 11; On slide block 7, be provided with teat, teat stretches out from slide block chute, between upper stroke switch 9 and lower stroke switch 8; The main contacts of contactor 11 and power supply 12, warning horn 13 connect and compose alarm circuit successively.
In the time that the displacement variable of instable slope is more than or equal to the spacing of slide block 7 and upper stroke switch 9 or lower stroke switch 8, wire rope 2 will pull slide block 7 to touch upper stroke switch 9, or pull slide block 7 to touch lower stroke switch 8 by tension spring 6, thereby contactor 11, power supply 12, warning horn 13 are communicated with and form a closed-loop path, warning horn 13 rings, reach fast, accurately report to the police.
Draw bad warning device for fear of the excessive wire rope 2 that causes of deflection, wire rope 2 forms by two sections, and the middle wire clips 3 that adopts connects, and in the time that deflection acquires a certain degree, the wire rope being connected by wire clips 3 will come off.And wire clips 3 can regulate length and the level of tightness of wire rope when mounted easily.
Shown in Fig. 1, in the installation process of autoalarm, the joint bar 1 in instable slope should have enough insertion depths, meets firm, the stable condition of inserting.In order to improve the degree of accuracy of warning device, joint bar 1 axially should be with steel pipe 4 axially identical.
In the present embodiment, joint bar 1 is arranged in (joint bar 1 buried depth 2.0m, exposes 2.0m) within the scope of instable slope.Warning device is arranged in the stabilized zone beyond instable slope, and warning device basis adopts C20 concreting (the wide * of long * high=1m*1m*1m) warning device basis to adopt 0.8m to fix joint bar 5 to connect (spacing 0.3m, buried depth 0.7m, exposes 0.1m).
In the work progress of warning device basis (the C20 concrete of 1.0 cubic metres), need in warning device basis, insert 6 fixing joint bars 5, for fixing steel pipe 4, fixing joint bar 5 spacing should match with steel pipe 4.
In warning device installation process, the spacing of adjustable slide block 7 and upper stroke switch 9 and lower stroke switch 8, thus can be issued to Rapid Alarm in the situation of drafting displacement variable.
Warning device power supply all adopts storage battery power supply, is connected with a large amount of circuits simultaneously, should take corresponding rainproof measure.
Warning horn should be placed on the wider place of spaciousness and overlay area.
