Abstract
The utility model relates to the technical field of auxiliary devices for monorail crane transportation, in particular to a pneumatic limiting device for a track switch of a monorail crane. The limiting device comprises an oil wire rope (1), a stop pin (2), a jack (3), a compressed air switch and a fixed pulley (4), wherein the jack (3) is arranged above the track switch of the monorail crane and connected with the compressed air switch; the front end of a piston rod of the jack (3) is connected with the oil wire rope (1); the fixed pulley (4) is arranged above the stop pin (2) and at one side near the jack (3); and the other end of the oil wire rope (1) is connected with the stop pin (2) through the fixed pulley (4). The pneumatic limiting device is characterized by reasonable structure, convenient operation, high automation degree, time and labor saving, safety, reliability and the like.
Description
Technical field
The utility model relates to a kind of technical field of monorail crane transportation auxiliary device, the pneumatic inhibiting device of specifically a kind of monorail crane track switch.
Background technology
Monorail crane transportation has at present become the important assistant conveyance mode in colliery, and air operated control has been adopted in stirring of monorail crane track switch, has reached conveniently purpose.Yet the inhibiting device of track switch still adopts the mode of artificial rope for traction to control, there is the slow-footed shortcoming of effort of taking a lot of work, and in the bigger tunnel of aspect ratio, manually be difficult to operation, once occurred because the track switch inhibiting device is not in place for this reason, track switch is not tight, cause taking place the accident that monorail crane locomotive string trouble slides down and causes the monorail crane locomotive to fall, not only influence is produced, and the locomotive driving personnel are brought personal injury.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of rational in infrastructure, easy to operate that the utility model provides, and the degree of automation height is time saving and energy saving, the safe and reliable pneumatic inhibiting device of monorail crane track switch.
The technical solution adopted in the utility model is: the pneumatic inhibiting device of a kind of monorail crane track switch, comprise oil thread rope and locating dowel pin, also comprise jack, air pressure switch and fixed pulley, described jack is arranged on the top of monorail crane track switch, jack is connected with air pressure switch, the piston rod front end of jack is connected with oil thread rope, and fixed pulley is arranged on locating dowel pin top that side near jack, and the other end of oil thread rope is connected with locating dowel pin through fixed pulley.
Because the utility model is provided with jack above the track switch of monorail crane, the piston rod front end of jack is connected with locating dowel pin by oil thread rope, make locating dowel pin mention or fall by air pressure switch control jack flexible, thereby realize the pneumatic position-limiting action of locating dowel pin, the utility model degree of automation height, time saving and energy saving, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise: oil thread rope 1, locating dowel pin 2, jack 3, air pressure switch and fixed pulley 4, described jack 3 is arranged on the track switch top of monorail crane, jack 3 is connected with air pressure switch, the piston rod front end of jack 3 is connected with oil thread rope 1, and fixed pulley 4 is arranged on locating dowel pin 2 tops that side near jack 3, and the other end of oil thread rope 1 is connected with locating dowel pin 2 through fixed pulley 4.
In the present embodiment, fixed pulley 4 is set to two, and the line of the point of attachment of locating dowel pin 2 and jack 3 and oil thread rope 1 is set to the symmetric line of two fixed pulleys 4.Make locating dowel pin 2 motions steadily.
During normal the use, the piston rod of jack 3 is for stretching out state, and locating dowel pin 2 is arranged in spacing hole and plays position-limiting action.When needs change the circulation line of monorail crane, start air pressure switch, jack 3 is shunk, the piston rod of jack 3 drives connected oil thread rope 1 when shrinking mentions the locating dowel pin 2 of track switch, and just rotatable at this moment turnout is to the position of regulation.If start air pressure switch once more, jack 3 piston rods are stretched out, locating dowel pin 2 resets, and falls in the spacing hole, reaches spacing effect.
Characteristics of the present utility model:
1, the mode that has solved artificial rope for traction is controlled the slow-footed shortcoming of effort of taking a lot of work that the track switch inhibiting device exists, and under the artificial unworkable situation in the bigger tunnel of aspect ratio, has demonstrated its preceence more.
2, solved artificial rope for traction control track switch inhibiting device effectively, cause the track switch inhibiting device not in place, track switch is not tight, cause monorail crane locomotive string trouble to slide down easily accident that locomotive falls, eliminated potential safety hazard, guaranteed the reliability of track switch inhibiting device, realized transporting safely, practicality is stronger, has application value.
Because characteristics such as it is rational in infrastructure, easy to operate that as seen this, the utlity model has, and the degree of automation height is time saving and energy saving, and is safe and reliable.
In the pneumatic inhibiting device technical field of monorail crane track switch; everyly include the top that described jack is arranged on monorail crane track switch; jack is connected with air pressure switch; the piston rod front end of jack is connected with oil thread rope; fixed pulley is arranged on locating dowel pin top that side near jack, the other end of oil thread rope through fixed pulley and locating dowel pin bonded assembly technology contents all in the scope that the utility model is protected.
