Technical Field
The invention belongs to the field of overhead passenger devices, and particularly relates to a broken shaft protection device of an overhead passenger device.
Background
The aerial passenger device is mainly used for transporting personnel in inclined roadways and level roadways of mines, and the working principle of the aerial passenger device is that a motor drives a driving wheel on a speed reducer to serve as a driving device, and an aerial stepless circulating steel wire rope is adopted to serve as traction bearing. The steel wire rope is mainly tensioned by a tail tensioning device and supported by a rope pulley along the way so as to maintain the winding degree and the tension of the steel wire rope between the riding wheels. The rope clip connects the manned hanging chair with the steel wire rope and carries out circulating operation with the manned hanging chair, so that the purpose of transporting personnel is achieved.
The aerial passenger device mainly comprises a driving device, a driving wheel, a driven wheel, a tensioning device, a steel wire rope, a supporting (pressing) wheel, an electric control seat, a passenger seat, a comprehensive protection device and the like. In the actual operation process, because the personnel constantly go up and down, the transportation load constantly changes, will produce reciprocal horizontal shearing force to the main shaft, easily arouses the fatigue of main shaft material, and then produces the crackle and splits even for the action wheel or follow driving wheel drop, thereby arouse the incident, cause the casualties.
The existing aerial passenger device is not provided with a safety protection device after the shaft of the driving wheel or the driven wheel is broken, only the nondestructive inspection of the two main shafts is strengthened from the side, the defects generated in the operation process of the main shafts are discovered as early as possible, the safety accidents are avoided, and the casualties or the equipment damage caused by the falling of the driving wheel or the driven wheel after the main shafts are suddenly broken cannot be fundamentally solved.
Disclosure of Invention
The technical problem that this application will be solved provides a disconnected axle protection device for aerial passenger device, can effectively solve the problem of the casualties accident that leads to the fact owing to connecting the main shaft fracture in the aerial passenger device operation process.
The technical scheme of the application is as follows:
the utility model provides an overhead passenger device's disconnected axle protection device, its characterized in that, includes hanging beam and bracket, the hanging beam sets up the inboard at the runner, the hanging beam is the steel pipe of two vertical settings, the bracket is including two horizontal poles and two vertical poles that are the groined type connection, the bracket cavity has been enclosed to two horizontal poles and two vertical poles middles, the hanging beam is do not connected to the one end of two horizontal poles is equallyd divide, the bracket sets up the below at the runner, the center of bracket cavity sets up with the center of runner relatively, four edge lengths of bracket cavity all are less than the diameter of runner.
Furthermore, vertical convex columns are arranged in the center positions of the four sides of the cavity of the bracket.
Furthermore, at least one group of long-arm travel switches are arranged on the cavity of the bracket, and the height of each long-arm travel switch is higher than that of the corresponding convex column.
Furthermore, the bracket is arranged horizontally, the hanging beam is arranged vertically, and one end of the bracket is welded with the bottom of the hanging beam to form an L shape.
The beneficial effect of this application does:
the aerial passenger device is convenient to use, avoids rapid downward movement of the rotating wheel after the shaft of the aerial passenger device is broken, stops the aerial passenger device, perfects the protective measures of the aerial passenger device, improves the operation safety of the system, and has remarkable economic and social benefits.

Fig. 1 is a schematic front view of the present invention;
fig. 2 is a schematic bottom view of the present invention.
In the figure: hanging beam 1, bracket 2, horizontal pole 21, vertical pole 22, bracket cavity 23, fixed platform 3, action wheel 4, follow driving wheel 5, projection 6, long arm travel switch 7, wire rope 8.
Detailed Description
The present application is further described with reference to the following description and detailed description of the preferred embodiments.
A broken shaft protection device of an overhead passenger device is characterized by comprising a hanging beam 1 and a bracket 2, wherein one end of the hanging beam 1 is fixed on a fixed platform 3, the other end of the hanging beam 1 is connected with the bracket 2, the hanging beam 1 is arranged on the inner side of a rotating wheel, the rotating wheel comprises a driving wheel 4 and a driven wheel 5, the hanging beam 1 is two vertically arranged steel pipes, the bracket 2 comprises two cross rods 21 and two longitudinal rods 22 which are connected in a # -shape, a bracket cavity 23 is enclosed between the two cross rods 21 and the two longitudinal rods 22, one end of each cross rod 21 is respectively connected with the hanging beam 1, the bracket 2 is arranged below the rotating wheel, the center of the bracket cavity 23 is opposite to the center of the rotating wheel, four side lengths of the bracket cavity 23 are smaller than the diameter of the rotating wheel, and the bracket 2 is installed to effectively prevent the driving wheel 4 or the driven wheel 5 from falling on the ground after the broken shaft, avoid taking place the accident of dropping, hanging beam 1 can effectually prevent that the action wheel or follow driving wheel slide to the inboard behind the broken axle.
Furthermore, vertical convex columns 6 are arranged in the center positions of the four sides of the bracket cavity 23, and the convex columns 6 can effectively prevent the driving wheel or the driven wheel from rotating by inertia after the shaft is broken, so that the driving wheel or the driven wheel is clamped by the convex columns.
Further, at least one group of long-arm travel switches 7 are arranged on the bracket cavity 23, the heights of the long-arm travel switches 7 are higher than those of the convex columns 6, the rotating wheel falls off to touch the long-arm travel switches 7, the long-arm travel switches 7 can cut off a power supply immediately after shaft breakage, electric locking is achieved, and further accidents are prevented.
Further, the bracket 2 is arranged horizontally, the hanging beam 1 is arranged vertically, and one end of the bracket is welded to the bottom of the hanging beam to form an L shape.
In the aerial passenger device operation in-process, if the main shaft splits, action wheel 4 drops, bracket 2 can hold action wheel 4, avoid action wheel 4 to drop, because wire rope 8's pulling force action wheel 4 can slide to the inboard after the main shaft splits, hanging beam 1 can prevent that action wheel 4 from further moving to the inboard, long arm travel switch 7 on the bracket can guarantee to cut off power supply immediately after the action wheel takes place to drop, realize electric shutting, effectively prevent casualties or equipment damage, projection 6 on the bracket can prevent action wheel 4 or from the inertial rotation after 5 fall of driving wheel, prevent further emergence accident.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
