Abstract
The invention relates to a drum shearer power supply cable protection device. The drum shearer power supply cable protection device comprises a microswitch, an upper cover, a lower cover, safety pins, bolts and a control ring. The upper cover and the lower cover are connected through the bolts. The control ring is installed in the upper cover and the lower cover. The microswitch is installed on the upper part of the upper cover, the lower part of the microswitch is fixedly connected with a spring, a steel ball is installed on the lower part of the spring, and the steel ball is attached to the surface of the control ring under the effect of the spring. The number of the safety pins is two, one safety pin is installed in the upper cover and the control ring, and the other safety pin is installed in the lower cover and the control ring. The drum shearer power supply cable protection device has the advantages that the structure design is reasonable, the cost is relatively low, etc. When a full force exceeding a maximum allowable pull force is applied to a cable, the safety pins break, the shearer stops working, the pull force is no longer applied to the cable, the protection on the cable is in time and effective, and a cable protection sheath is prevented from being torn due to a too small bending radium of a cable elbow.
Description
Technical field
The present invention relates to cable protection equipment technology field, specifically a kind of flitting service cableProtective device.
Background technology
Coal-winning machine service cable is the pith that ensures the normal work of coal-winning machine, and flitting is at working faceIn the process of working in reciprocating mode, service cable is mainly protected and is dragged by the cable handler of flitting back and forth.But cable handler environment in the time of work is severe, sometimes can lose efficacy to the protection of cable, causes service cable to be subject toTo pulling force, in order to make cable not be subject to pulling force, working site is generally to hold first cable clamp by ropePin-and-hole place, after use after a while (be generally about two weeks), in order to ensure ropeSecurity, workman can replace rope again, but change be a more loaded down with trivial details process. AndIf the time is too of a specified duration, can reduce in the cable surplus of cable elbow, the bending radius of cable is too small, and having canCan be able to make cable receive the risk of bending damage, this just need to take out cable from cable handler, thenAgain penetrate again, make cable elbow have enough cable length surpluses, ensure larger bending radius.Time and effort consuming like this, has had a strong impact on the operating efficiency of working face, has increased workman's labour intensity, and has givenThe safety of cable has been brought hidden danger.
Summary of the invention
It is a kind of reasonable in design, lower-cost that technical problem to be solved by this invention is to provide,Can realize the device to cable protection, i.e. a kind of flitting service cable protective device.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of flitting service cable protective device, comprise microswitch, upper cover, lower cover, safety pin,Bolt and control loop. Described upper cover top is provided with square groove, and described square groove middle part is provided with one number service hole, described onThe portion that covers is also provided with door, and described door is positioned at square groove top, is covered with through hole No. two on described, described inUpper cover both sides end face is equipped with annular groove No. one, and described upper cover middle part is provided with semicircle groove No. one, described No. oneSemicircle groove is provided with No. three through holes and No. four through holes, described one number service hole and No. three through hole concentrics, described inUpper cover top is also provided with pin-and-hole No. one, and a pin-and-hole and No. four through hole concentrics. Upper cover can be arranged on and adoptOn the electric cabinet of coal machine.
Under described, be covered with four screwed holes, described lower cover both sides end face is equipped with annular groove No. two, described No. twoAnnular groove is provided with through hole No. five, and described lower cover middle part is provided with semicircle groove, described No. two semicircle grooves No. twoBe provided with through hole No. five, and No. five through holes and described No. five through hole concentrics.
Because upper cover both sides end face is equipped with annular groove No. one, lower cover both sides end face is equipped with annular groove No. two, when upperWhen lid is connected with lower cover, a complete groove can be formed, the installation of other parts can be facilitated like thisWith dismounting, can also alleviate the weight of whole part, make flitting service cable protective device install,Transport, keep in repair convenient.
Described control loop is tubbiness, and described control loop one end is provided with clamp screw consent, and clamp screw consent quantityBe four, in described clamp screw consent, tightening plug screw be installed, when cable is through after control loop, use tighteningPlug screw compress cable jacket, now cable can with control loop keep relative fixing, described control loop anotherEnd is provided with pin-and-hole No. two, and described No. two pin-and-holes have two, and two pin-and-holes are distributed in the same circular section of control loop,And axle center conllinear, described control loop middle part is hollow-core construction. Hollow-core construction penetrates for cable.
Described upper cover is connected by bolt with lower cover, the circle of a described annular groove and No. two annular groove completes,Described control loop is arranged in the circle of an annular groove and No. two annular groove formations; Described microswitch is arranged on square grooveIn, described microswitch below is fixed with spring, and described spring is through one number service hole and No. three through holes, instituteState spring below steel ball is installed, described steel ball is attached to control loop surface under the effect of spring; Described safetyPin has two, and one of them safety pin is arranged in upper cover and control loop, and another one safety pin is arranged on downIn lid and control loop. Safety pin makes control loop keep relative fixing with upper cover and lower cover, is drawn at cableWhen power, the same under tension of safety pin, in the time that pulling force exceedes the allowable stress of safety pin, safety pin can be sent outRaw fracture, the allowable stress of safety pin is less than the maximum pull that cable can bear. Microswitch is installingCheng Hou, connects with the gauge tap of coal-winning machine, if microswitch in closure state, coal-winning machine can be justNormal work, if microswitch in off-state, coal-winning machine quits work. Spring and steel ball can ensureMicroswitch is in pressured state, and now microswitch is in closure state. When cable under tension excessive,Shear pin breakage, control loop can be pulled out from upper cover and lower cover, and now steel ball and control loop depart from, at bulletUnder spring effect, steel ball comes off, now pressurized not of microswitch, and in off-state, coal-winning machine stops workDo, cable can not continue to be subject to pulling force, has effectively protected cable.
Described control loop is provided with arcwall face, and described steel ball is attached on arcwall face. Be adjacent to after arcwall face at steel ball,The structure of arcwall face can make steel ball that Slideslip, displacement phenomenon can not occur.
The diameter of described steel ball is less than the internal diameter of No. three through holes, can ensure like this at flitting power supply electricityAfter the installation of cable protection device, steel ball is close on arcwall face under the effect of spring, can ensure fine motionSwitch, in closure state, ensures the normal work of coal-winning machine.
The invention has the beneficial effects as follows: the present invention has the advantages such as reasonable in design, cost be lower. Work as electricityWhen the pulling force that cable is subject to exceedes the maximum pull of permission, safety pin can rupture, and now microswitch can disconnect,Coal-winning machine quits work, and makes cable not be subject to pulling force, timely and effective to the protection of cable, and can protectThe bending radius of card cable elbow can be not too small, and cause cable protective sleeve to be torn.
