Abstract

The utility model belongs to mine promotes transportation equipment field, concretely relates to cage accepts equipment pivot and shifts up cradle. The track rocker comprises rocker arms, rocker tips at the front ends of the rocker arms, balance weights at the rear ends of the rocker arms, a driving device, a supporting device, a guide rail lining and a connecting device between the two rocker arms, and is characterized in that rocker arm rotating shafts are half shafts and are respectively fixed on the outer sides of the two rocker arms, and the central lines of the rocker arm rotating shafts are higher than the bottom plane of a track. The distance between the central line of the rotating shaft of the swing platform and the upper plane of the rail is small, so that the gap between the rails at the rotating shaft of the swing arm is also small, the running impact of the mine car is small at the position, and the accident that the mine car falls off the rail is not easy to happen. Similarly, the track clearance of the car pusher is small, when the car pusher chain passes through the shaking table, the car pusher runs stably, and the phenomena of clamping and derailing of the car pusher chain can not occur. The whole running process of the mine car is stable and the mine car is not easy to fall off.

Description

Shaft up-shifting swing

Technical field

The utility model belongs to mine hoisting transportation device field, is specifically related to a kind of cage and accepts the equipment shaft up-shifting swing.

Background technology

In the mine that the active tank cage promotes, cage chair is to use the most widely cage to accept equipment.Existing cage chair has enough rigidity in order to make rocking arm; rocker shaft is an axis; interfere for fear of rocker shaft and car puller track simultaneously; shaft centerline must have big separation apart from rail level; the hunting range in the assurance cage chair operational process, between rocker shaft place tramroad enough gaps must be arranged, so tramroad gap, rocker shaft place is bigger; operational shock is bigger herein to cause mine car, and the mine car accident that slides down easily takes place; In like manner, car puller track gap herein is also bigger, and operational shock is bigger when causing car puller to pass through this gap, easily take place the chain link card not, derailment occurring, fault rate is higher.

Summary of the invention

The purpose of this utility model is to provide a kind of can guarantee mine car, steady, the smooth and easy shaft up-shifting swing that passes through of car puller.

The utility model is achieved through the following technical solutions:

It is a kind of shaft up-shifting swing, the counterweight, actuating device, bracing or strutting arrangement, guide rail lining, the middle connecting device of two rocking arms that comprise the rear end of shaking point and rocking arm of rocking arm and rocking arm front end, it is characterized in that rocker shaft is a semiaxis, be separately fixed at the two rocking arms outside, the rocker shaft line of centers is higher than the track baseplane.

Described guide rail lining is fixed on the cage, is provided with twilight orbit and guard rail.

Cage chair lifts when falling work and rotates around the rocker shaft line of centers, be to guarantee the hunting range in the cage chair operational process; between rocker shaft place tramroad enough gaps must be arranged; this gap increases with the increase of plan range on the tramroad of rocker shaft line of centers; when on rocker shaft line of centers and the tramroad during planes overlapping, orbit gap can reach minimum.

The rocker shaft line of centers is higher than the tramroad baseplane, less apart from planar dimension on the tramroad, so tramroad gap, rocker shaft place is also less, when mine car when tramroad reaches rocking arm, mine car operational shock herein is less, the difficult accident that slides down.In like manner, the car puller orbit gap is also less, when go-cart unit chain when the cage chair, the car puller operation is also more steady, can not take place go-cart unit chain card not, derailment occurring.

Owing to float in the position of cage, cage chair shakes a point and a jar inner orbit in-line, shakes point and is overlapped on smoothly on the cage for making, and shaking point must have enough gaps with a jar inner orbit.When mine car travelled when shaking point and entering cage by guide rail lining, tramcar wheel is along reaching a jar inner orbit through the twilight orbit on the guide rail lining, and twilight orbit has played the effect of shaking point and jar inner orbit that connects.The guide rail lining is provided with the guard rail to the tramcar wheel guiding, and mine car is operated steadily when point enters cage by shaking, and is difficult for sliding down.

Because be provided with the car puller track between two rocking arms, after moving on the rocker shaft, the middle part should disconnect, adopt semiaxis.

The utlity model has simple in structurely, mine car is difficult for sliding down, and the advantage that car puller operates steadily can be widely used in the accepting of cage of vertical shaft hoistings such as coal, mine.

As shown in FIG.: 1 cage, 2 shake point, 3 rocking arms, 4 mine cars, 5 actuating devices, 6 tramroads, 7 counterweights, 8 bracing or strutting arrangements, 9 go-cart unit chains, 10 car puller tracks, 11 tramroad baseplanes, 12 guide rails lining, 13 tramroad gaps, 14 rocker shafts, 15 car puller orbit gaps, 16 jars of inner orbits, 17 tramcar wheels, 18 tramcar wheel edges, 19 guard rails, 20 twilight orbits, the direction that the A rocking arm rotates.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises rocking arm 3, rocking arm 3 front ends shake point 2; counterweight 7 of rocking arm 3 rear ends, actuating device 5, bracing or strutting arrangement 8; guide rail lining 9, shake point 2 and rocking arm 3 and be connected by hinge, rocking arm 3 pass through rocker shaft 14 and bracing or strutting arrangement 8 hinged.Rocker shaft 14 is a semiaxis, is separately fixed at two rocking arms, 3 outsides, and rocker shaft 14 line of centerss are higher than track baseplane 11, and guide rail lining 12 is fixed on the cage 1, is provided with twilight orbit 20 and guard rail 19.

During the utility model work, cage chair lifts when falling work and rotates around rocker shaft 14 line of centerss, be to guarantee the hunting range in the cage chair operational process; 6 of rocker shaft 14 place's tramroads must have enough gaps; this gap increases with the increase of plan range on the tramroad 6 of rocker shaft 14 line of centerss; when on rocker shaft 14 line of centerss and the tramroad 6 during planes overlapping, tramroad gap 13 can reach minimum.

Rocker shaft 14 line of centerss are higher than tramroad baseplane 11, less apart from planar dimension on the tramroad 6, so tramroad gap 13, rocker shaft 14 place is also less, when mine car 4 when tramroad 6 reaches rocking arm 3, mine car 4 operational shock herein is less, the difficult accident that slides down.In like manner, car puller orbit gap 15 is also less, and when go-cart unit chain 9 passed through cage chair, the car puller operation was also more steady, and other, the derailment occurring of go-cart unit chain 9 cards can not take place.

Owing to float in the position of cage 1, shake a point 2 and jar inner orbit 16 in-lines, shake point 2 and be overlapped on smoothly on the cage 1 for making, shaking point 1 must have enough gaps with a jar inner orbit 16.When mine car travelled when shaking point 1 and entering cage by guide rail lining 12, tramcar wheel reaches jar inner orbit 16 along 18 through the twilight orbits 21 on the guide rails lining 12, and twilight orbit 19 has played the effect of shaking point 2 and jar inner orbit 16 that connects.The guard rail 19 that guide rail lining 12 is provided with tramcar wheel 17 guiding makes mine car 4 operate steadily when point 2 enters cage 1 by shaking, and is difficult for sliding down.
