Abstract
The utility model discloses a device preventing insufficient closing of a shaft elevator skip. An overtravel-limit switch is arranged at the left side of the mouth of the current shaft; the normally closed contact of the overtravel-limit switch is connected with the control loop of the shaft elevator skip in series; the probe of the overtravel-limit switch faces to the shaft elevator skip and the horizontal distance between the probe and the shaft elevator skip is 10-20mm. When the shaft elevator skip is descended into the well under the state of being insufficiently closed, the left side of the shaft elevator skip can contact the probe, then the probe drives the normally closed contact inside the overtravel-limit switch to be disconnected, thereby cutting off the control loop of the shaft elevator skip; then the elevator is powered off and stops working, thereby avoiding elevating accidents and guaranteeing safe production.
Description
Technical field
The utility model relates to the vertical shaft winder skip bucket, relates in particular to a kind of device that prevents that the vertical shaft winder skip bucket is not closed completely.
Background technology
The vertical shaft winder skip bucket is the container that is used to load mineral, as shown in Figure 1, existing vertical shaft winder skip bucket comprises bucket frame 1, the top of bucket frame 1 is equipped with bucket case 3 by last S. A. 2, the right side, bottom of bucket case 3 is equipped with the bucket end 5 by following S. A. 4, the bottom at the bucket end 5 is equipped with tugboat 6, and bucket frame 1 bottom is equipped with the low right high stepped tugboat bend 7 in a left side, and tugboat 6 contacts with tugboat bend 7 and can roll along the upper surface of tugboat bend 7.In conjunction with Fig. 2, when the vertical shaft winder skip bucket need unload, the push rod 9 that is installed on bucket case 3 right sides promotes bucket case 3 made its underpart tilt to dumping apron 8 tops to the left, opens the bucket end 5 then and just the mineral in the vertical shaft winder skip bucket can be unloaded.Under the normal circumstances, after having unloaded when push rod 9 retraction drives vertical shaft winder skip bucket returns, tugboat 6 passive sliding to the right until the bucket end 5 is closed fully along tugboat bend 7.Yet foreign material such as finger stone is arranged are blocked sometimes with the junction of bucket case 3 in the bucket end 5, thereby cause the vertical shaft winder skip bucket to be not closed completely, the bottom of vertical shaft winder skip bucket will be tilted to the left slightly, in case the lifting accident will take place in well operations under the vertical shaft winder skip bucket under this state, the influence safety in production.
The utility model content
The purpose of this utility model is to provide a kind of device that can prevent that the vertical shaft winder skip bucket is not closed completely, the lifting accident that occurs to prevent therefore.
For achieving the above object, the utility model provides a kind of device that prevents that the vertical shaft winder skip bucket is not closed completely, comprise the travel switch that is fixed on left side, vertical shaft well head place, the normally closed contact of described travel switch is serially connected with on the control loop of vertical shaft winder skip bucket, the probe of described travel switch towards described vertical shaft winder skip bucket and and horizontal throw between it be 10～20 millimeters.
The device that prevents that the vertical shaft winder skip bucket is not closed completely of the present utility model, described travel switch are the JLXK1-511 travel switch.
The device that prevents that the vertical shaft winder skip bucket is not closed completely of the present utility model, described travel switch is installed on the guardrail that is positioned at described vertical shaft well head.
The device that prevents that the vertical shaft winder skip bucket is not closed completely of the present utility model, described travel switch are installed on by an oblong iron plate and are positioned on the described guardrail.
The device that prevents that the vertical shaft winder skip bucket is not closed completely of the present utility model is in left side, existing vertical shaft well head place a travel switch to be installed, the normally closed contact of travel switch is serially connected with on the control loop of vertical shaft winder skip bucket, the probe of travel switch towards the vertical shaft winder skip bucket and and horizontal throw between it be 10～20 millimeters.Under being not closed completely state, the vertical shaft winder skip bucket goes into the well, probe will be run in the left side of this vertical shaft winder skip bucket, probe then drives the inner normally closed contact of travel switch and disconnects, thereby cut off the control loop of vertical shaft winder skip bucket, the gig outage quits work, thereby avoided the lifting accident, guaranteed safety in production.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail:
With reference to figure 3, the device that prevents that the vertical shaft winder skip bucket is not closed completely of the present utility model comprises the oblong iron plate 304 of guardrail 303 inside top that are welded on vertical shaft well head left side, is fixed with JLXK1-511 travel switch 301 on the oblong iron plate 304.In conjunction with Fig. 4, the normally closed contact 305 of this JLXK1-511 travel switch 301 is serially connected with on the control loop 306 of vertical shaft winder skip bucket, and the probe 302 of this JLXK1-511 travel switch 301 towards the vertical shaft winder skip bucket and and the horizontal throw of vertical shaft winder skip bucket between 10～20 millimeters.At the bottom of the bucket of vertical shaft winder skip bucket, block foreign material such as finger stone is arranged sometimes with the junction of bucket case, the vertical shaft winder skip bucket is not closed completely, the bottom of vertical shaft winder skip bucket will be tilted to the left slightly, owing between the level of probe 302 and vertical shaft winder skip bucket under the normal closed condition of vertical shaft winder skip bucket 10～20 mm distance are only arranged.Therefore, in case the vertical shaft winder skip bucket is gone into the well under the state of being not closed completely, probe 302 will be run in the left side of this vertical shaft winder skip bucket, pop one's head in 302 and drive the 301 inner normally closed contacts disconnections of JLXK1-511 travel switch, thereby cut off the control loop 306 of vertical shaft winder skip bucket, the gig outage quits work, thereby has avoided the lifting accident, has guaranteed safety in production.Wherein, travel switch claims limit switch or position switch again.It is a kind of according to movable parts travel position and the control apparatus of commutation circuit mode of operation.The operating principle of travel switch is similar to control button, usually be used in the machine equipment, in advance travel switch is installed on certain travel position according to technological requirement during use, the be in operation probe that touches travel switch of parts makes the contact action of travel switch and realizes the switching of circuit, reaches the purpose of controlled motion parts travel position.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
