Abstract
The utility model provides a kind of paddle coal feeder flat cable tension force fender guard, belongs to power industry fender guard technical field.This device comprises proximity switch, elastic element.This device utilizes elastic element to carry out deformation monitoring, and when the tension force drawn and push away both direction is increased to a certain degree, deformation of elastic element reaches 5mm; touch proximity switch; proximity switch sends signal, and paddle coal feeder is shut down, thus reaches the object of protection cable.This device can when paddle coal feeder limit switch fault, coaster bite and misoperation, timely action protection cable and miscellaneous part, and this device makes simple, and cost is low, can increase work efficiency.
Description
Technical field
The utility model relates to power industry fender guard technical field, refers to a kind of paddle coal feeder flat cable tension force fender guard especially.
Background technology
Paddle coal feeder is indispensable major equipment in thermal powerplant mounted in slotted coal channel, and it along the longitudinal axle track walking of coal ditch or can be parked in a place by coal quantitatively, push on coal conveyer belt uniformly continous.Paddle coal feeder reliable operation, directly has influence on the safety and stability of whole coal handling system.Paddle coal feeder is powered to working motor by flat cable.Flat cable is overlapped on coaster or slip, and then linked in order to protect cable by steel rope, before and after paddle coal feeder, end position is provided with mechanical trip switch in order to protect paddle coal feeder and cable.And due to coal handling system Dust Capacity larger; and paddle coal feeder is general all at below ground; humidity is larger; coaster or slip bite, wearing and tearing are more serious; often there is the situation that coaster or slip are broken; now operating personal will cause the possibility that power cable is torn, breaks unless you give your whole attention to it; if the limit switch malfunctioning cable that also can cause in front and back is torn, is broken in addition; and accident fault miscellaneous part may be expanded further; do not have cable installed protection device in actual production at present, make in production, to there is very large potential safety hazard.
Therefore, can effectively avoid cable failure for available protecting flat cable and related accessories install tension force protection additional, break.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of paddle coal feeder flat cable tension force fender guard.
This device comprises proximity switch, elastic element one and elastic element two.
Wherein, proximity switch is arranged on elastic element one, and accesses paddle coal feeder control loop; Elastic element one and elastic element two are welded on fixing channel-section steel two ends respectively; Elastic element one, elastic element two are positioned at paddle coal feeder coaster side, and are connected with steel rope respectively.
Proximity switch is switch-type sensor, and elastic element one and elastic element two are made up of grid material.
The gap of proximity switch and elastic element two is operating distance+4 ~ 6mm of proximity switch.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme; tension force fender guard is installed additional to the power cable of existing paddle coal feeder; the cable effectively avoiding maloperation, equipment appurtenance bite, limit switch failure and other reasons to cause breaks and even breaks; actv. protects paddle coal feeder cable and other annexes; increase work efficiency; and this device makes simply, cost is low, is applicable to the cable protection of all paddle coal feeders.
Accompanying drawing explanation
Fig. 1 is the structural representation of paddle coal feeder cable stretch fender guard of the present utility model.
In figure,
1-proximity switch; 2-elastic element one; 3-elastic element two; 4-coaster; 5-steel rope.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1; the paddle coal feeder flat cable tension force fender guard that the utility model proposes; elastic element 1 and elastic element 23 is welded respectively at fixing channel-section steel two ends; proximity switch 1 is arranged on elastic element 1; and access paddle coal feeder control loop; elastic element 1 and elastic element 23 connecting steel wire ropes 5 respectively, the other end of steel rope 5 is connected on coaster 4, and flat cable is overlapped on coaster 4.Wherein, proximity switch 1 adopts switch-type sensor, and the characteristic of its existing travel switch, micro-switch, has sensing capabilities simultaneously, and reliable in action, stable performance, frequency response is fast, application life is long, and antijamming capability is strong, and has the features such as waterproof, shockproof, withstanding corrosion; Elastic element 1 and elastic element 23 are made up of grid material, and make simple, cost is low.
During this device is applied at the scene; elastic element one is connected to detect pulling force with the steel rope of coaster with elastic element two; when coaster bite; the stress pushing away, draw both direction increases, and elastic element 1 and elastic element 23 deform, when elastic element 1 and elastic element 23 distortion reach 5mm; touch proximity switch 1; proximity switch 1 sends signal, and paddle coal feeder is shut down, thus avoids the accidents such as steel rope is broken, cable is broken generation.
The gap of proximity switch and elastic element two is carried out debugging by on-the-spot real-world operation and is determined, for proximity switch operating distance+4 ~ 6mm, this gap makes proximity switch not malfunction also can not tripping, cause equipment irregular operating or damage, moreover elastic element one and elastic element two will have suitable flexibility, can recover in time after there is deformation.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
