Abstract

The invention relates to an automatic tank-locking cradle. The automatic tank-locking cradle is fixed in the mouth of a well and/or a parking lot at the bottom of the well and forms an automatic tank-stopping and lifter control device which consists of a lock head, a control switch, a pressure spring, a lock disc, an oil cylinder, a bracket and a shaking tip. The automatic tank-locking cradle at the bottom of the well serves as the starting point of automatic control; two modes of controlling power failure of the lifter are adopted and comprise a well bottom control mode and a well mouth mode; when the well bottom control mode is adopted, the cradle of other modes or the cradle of the mode can be adopted at the well mouth to automatically lock a lifting container reaching the starting point at the parking lot at the bottom of the well under the non-repair state, a lifter control circuit is started, the lifter is in power failure, brakes and stops, and the containers at the mouth of the well and the bottom of the well stops at the same time; if the control circuit is provided with a delay switch, the container at the mouth of the well continuously lifts after the container at the bottom of the well is locked, the lifter is in power failure, brakes and stops after delay, and the container at the mouth of the well stops; when the well mouth control mode is adopted, the control switch of the cradle at the mouth of the well controls the lifter circuit to be in power failure after the cradle at the bottom of the well is locked, the lifter brakes and stops, and the container arriving at the mouth of the well stops.

Description

Automatic lock jar cage chair

Technical field

The present invention relates to a kind of catching device of mine hoisting container, specifically is a kind of automatic lock jar cage chair, when lifting container arrives well head or shaft bottom stop position; This device cuts off the power supply gig automatically; Band-type brake stops, and is widely used in belonging to the mining machinery field in the lifting yarn system of colliery metallurgical mine.

Background technology

The metallurgy industry in the colliery at present, the mode of accepting of lifting container extensively adopts the long-armed type cage chair, but container bob and the bigger problem of the power that is hit when existing loading and unloading; To deep-well and the bigger container of deadweight; Because it is inaccurate to stop jar position, makes the rocking arm lift angle excessive, sometimes even can't use; Though existing have new product to occur, each item performance figure can't reach satisfied requirement.

Summary of the invention

The objective of the invention is in order to overcome the weak point of above-mentioned prior art, a kind of automatic lock jar cage chair be provided, it be fixed on well head discord (or) shaft station, forms a kind of jar and hoister control device of stopping automatically; By tapered end, master cock, stage clip, lock collar, oil cylinder, support and shake point and forms, do the automatically controlled actuation point with the automatic lock jar cage chair in shaft bottom, the mode that adopts two kinds of control gigs to cut off the power supply, promptly the shaft bottom is controlled and the well head mode; When adopting shaft bottom control, well head can adopt the cage chair of other form, also can adopt the cage chair of this form, pins the lifting container that arrives this point under the non-inspecting state automatically in the shaft station; While start-up control gig circuit, gig outage at this moment, band-type brake stops, and well head and shaft bottom container stop simultaneously; If control circuit has time-delay switch, after the shaft bottom container was lockable, the well head container continued to rise; After time-delay, the gig outage, band-type brake stops; The well head container stops, when adopting well head control, after the shaft bottom cage chair pins; The master cock control gig down circuitry of well head cage chair, band-type brake stops, and the container that arrives well head is stopped.

The present invention realizes with following technical scheme: a kind of automatic lock jar cage chair is characterized in that: it comprises two tapered ends that have gradient, and is rack-mount, is connected with master cock on the tapered end; There is stage clip at the tapered end rear portion, and baffle plate is arranged on the tapered end, and tapered end can move along the front and back horizontal direction; Symmetrical midline at two tapered ends has axle, is fixed by front and back bearings, and lock collar is fixed on the axle; The lock collar two ends are wedge forms, and the lock collar two ends are connected with connecting rod, with shake the point be connected; Also be fixed with lever on the axle, lever can link to each other with oil cylinder, also can link to each other with manual handle.

Described tapered end and support adopt the friction of rolling mode to be associated, and have yielding rubber.

Described master cock adopts various ways, and the pinning action of lock collar and the certain speed value of lifting container are linked, when values for actual speed during less than the velocity amplitude of setting; Lock collar action, when values for actual speed during greater than the velocity amplitude set, lock collar is failure to actuate; But the gig outage, the drg band-type brake.

Advantage of the present invention is: mine hoisting system easily is automated, and it is accurate to stop jar position, no longer beats during the lifting container loading and unloading, eliminates the suffered impact of hoisting rope when starting and stopping basically, has improved the stressed of whole elevator system.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is described further:

The specific embodiment

As shown in the figure: a kind of automatic lock jar cage chair is characterized in that: it comprises two tapered ends 1 that have gradient, installs on the support 12, is connected with master cock 9 on the tapered end; There is stage clip 4 at the tapered end rear portion, and baffle plate 2 is arranged on the tapered end, and horizontal direction moved before and after tapered end can prolong; Symmetrical midline at two tapered ends has axle 10, and fixing with rear bearing 8 by front bearing 11, lock collar 3 is fixed on the axle; Lock collar two ends band wedge form, the lock collar two ends are connected with connecting rod 14, and shake point and 13 are connected; Also be fixed with bar bar 6 on the axle, lever can link to each other with oil cylinder 5, also can link to each other with manual handle 7.

Described tapered end 1 adopts the friction of rolling mode to be associated with support 12, has yielding rubber.

Described master cock 9 adopts various ways, and the pinning action of lock collar 3 and the certain speed value of lifting container 18 are linked.

Working process: when adopting the shaft bottom mode, under non-inspecting state, rigidly connect when touching tapered end 1 when lifting container 18 low speed drop to, tapered end 1 is pushed back gradually; Lifting container 18 continues low speed and descends, and tapered end 1 progresses in the lock fangs 19 on lifting container 18 chassis, and tapered end 1 stretches out gradually, when tapered end 1 stretches out fully; Master cock 9 actions start oil cylinder 5, and lock collar 3 is rotated, and pins tapered end 1; While start-up control gig circuit, if time-delay switch is arranged, the well head container can continue upwards to move a segment distance, gig outage then; Band-type brake stops, if there is not time-delay switch, gig cuts off the power supply immediately, and well head and shaft bottom container stop simultaneously; When adopting the well head mode, its process is basic identical, and different is the outage of removing to control gig with the tapered end and the master cock of well head cage chair, and band-type brake stops.
