Description

A kind of overhead man-riding chair lift reversing arrangement and commutation method

Technical field

The present invention relates to a kind of overhead man-riding chair lift reversing arrangement and commutation method, belong to mining equipment field, be particularly suited for mine overhead passenger device.

Background technology

Mine overhead passenger device (is commonly called as monkey car) and is a kind of mine working and transports the transporting equipment of personnel, and the practical situation in tunnel have decided on whether can installing rack overhead manned device, the overhead manned equipment chair lift width both sides of Bidirectional circulation should have certain safe distance, when span length does not reach the safe distance of Bidirectional circulation, common chair lift can only travel in the same direction, just can not pass through. And the suitability of chair lift determines the mounting condition in tunnel, therefore how realizing one and also can install monkey car in narrow opening, the technical scheme of chair lift need to research and solve.

Summary of the invention

In order to solve in existing tunnel, the safety traffic of narrow opening monkey car and road ability problem, it is desirable to provide a kind of overhead man-riding chair lift reversing arrangement, this overhead man-riding chair lift reversing arrangement simple in construction, commutation simplicity, low cost of manufacture.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of overhead man-riding chair lift reversing arrangement, is used for being arranged between chair lift top pipe and chair lift lower circular pipe; It is structurally characterized in that, and described overhead man-riding chair lift reversing arrangement includes commutation rotating shaft; The lower end of the top of described commutation rotating shaft and described chair lift top pipe is fixedly linked, the outer sheathed adapter sleeve of this commutation rotating shaft, the bottom of this adapter sleeve and described chair lift lower circular pipe top are fixedly linked, and the top end face of described commutation rotating shaft lower surface and chair lift lower circular pipe has gap; The outer wall of described commutation rotating shaft is provided with radially grooving and axial grooving, and this radial direction grooving is connected with multiple axial grooving in communication; The inwall of described adapter sleeve is provided with and is placed in radial direction grooving or axial grooving and for the positioning convex for positioning chair lift.

Thus, it is desirable to during commutation, make to move on chair lift lower circular pipe and adapter sleeve, and rotate to required direction, positioning convex falls in corresponding axially grooving, it is achieved commutation.

According to embodiments of the invention, it is also possible to the present invention to be done further optimization, the below technical scheme for being formed after optimizing:

Preferably, the radial direction grooving place of described commutation rotating shaft forms axle journal. Further, described positioning convex can rotate freely around the axle journal of commutation rotating shaft when chair lift commutates.

As a kind of concrete version, described positioning convex is through described adapter sleeve and extension pin that to be fixed on adapter sleeve prominent to adapter sleeve inwall.

The reliability that the lower end on top with described chair lift top pipe in order to ensure commutation rotating shaft is fixedly linked, the external wall of upper portion of described commutation rotating shaft is provided with the step preventing chair lift top pipe from moving down, and the lower surface of this step and the upper surface of adapter sleeve exist gap.

Preferably, the gap between described commutation rotating shaft lower surface and the top end face of chair lift lower circular pipe is more than the groove depth of axial grooving, and the gap of the upper surface of the lower surface of step and adapter sleeve is more than the groove depth of axial grooving.

In order to realize coming and going the commutation between both direction, described commutation rotating shaft is provided with two axial groovings, and two axial groovings are oppositely arranged.

Thus, chair lift top round tube inside diameter is socketed on the step upper outside of commutation rotating shaft by the reversing arrangement of the present invention, the bottom of commutation rotating shaft has rotatable radial direction grooving location, have under rotatable radial direction grooving and position no less than an axial grooving, the internal diameter of adapter sleeve is socketed on the external diameter of commutation rotating shaft, the internal diameter of adapter sleeve is connected with chair lift lower circular pipe external diameter, hang pin to be connected by adapter sleeve, have in rotatable radial direction grooving in the bottom of commutation rotating shaft, when taking, commutation turns the tip of the axis and certain gap is left in chair lift bottom, when commutation, chair lift bottom and adapter sleeve are integrated when being lifted up, chair lift lower tip and commutation rotating shaft leave certain interval, also matched in clearance under adapter sleeve inner-diameter portion whose and commutation rotating shaft step, it is made to rotate flexibly, after commutation, hang when taking in the radial direction grooving that pin drops on commutation rotating shaft, it is made all around not swing, for this, the problem taken that quickly commutates of chair lift can be solved.

Based on same inventive concept, present invention also offers a kind of method utilizing above-mentioned overhead man-riding chair lift reversing arrangement that chair lift is commutated, it comprises the steps:

1) during normal operation, positioning convex is positioned at axial grooving, it is necessary to during commutation, and one hands of user catches chair lift top pipe, another hands catches chair lift lower circular pipe, pulls shifting on chair lift lower circular pipe to make positioning convex depart from axial grooving and enter in radial cut groove simultaneously;

2) rotating chair lift lower circular pipe, positioning convex rotates around radial direction grooving, until proceeding to the direction of needs, then unclamps chair lift lower circular pipe, relies on chair lift gravity, and positioning convex falls in corresponding radially grooving, it is achieved commutation.

Compared with prior art, the invention has the beneficial effects as follows: the chair lift apparatus structure capable of reversing of the present invention is simple, commutation simplicity, low cost of manufacture, is the propagable product of the one of chair lift in existing mine overhead passenger device.

Below in conjunction with drawings and Examples, the present invention is further elaborated.
