Abstract
The utility model discloses a rope loosing protective device for mine hoists and aims at providing the rope loosing protective device for mine hoists. The rope loosing protective device for mine hoists comprises a steel pipe, a pre-tightening nut, a spring seat, a spring, a supporting seat, a bolt, a sleeve and a stroke switch and is characterized in that one end of the bolt is connected with the steel pipe and the pre-tightening nut through screw threads, and the other end of the bolt is connected with the supporting seat through the sleeve arranged outside the bolt. The spring is arranged between the sleeve and the spring seat and sleeved with the bolt, and the stroke switch is connected with the supporting seat through screw threads and arranged under the bolt. The rope loosing protective device for mine hoists is mainly used for mine hoists.
Description
Technical field
The utility model relates to a kind of fender guard, relates in particular to a kind of mine hoist and uses the rope creep protection device.
Background technology
Traditional rope creep protection device (mine hoist parts) that mine is used is realized with a travel switch; Promptly fix a travel switch (the bracing frame other end is an articulated structure) with bracing frame at the one of which end at winding houses steel rope rope outlet place; Bracing frame is positioned at the steel rope below; During the gig normal operation, be wrapped in steel rope on the elevator drum along cylinder axis direction sway, this moment, steel rope and travel switch had certain vertical distance.But owing in lifting process, having disconnected rope, card jar, crossing and reason such as put, be pressed onto travel switch this moment when steel rope can cause it sagging because of slack rope, the travel switch normally closed contact breaks off safety return circuit makes gig carry out safety arrestment.But because gig steel rope when work is along cylinder axis direction sway; When steel rope drops on the bracing frame pin jointed end when slack rope; The protection of travel switch action just possibly is failure to actuate or move untimely, thus just might be when slack rope occurring gig can not carry out safety arrestment and have an accident.
Summary of the invention
The purpose of the utility model is to provide a kind of mine hoist to use the rope creep protection device, to overcome above-mentioned drawback.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of mine hoist is used the rope creep protection device; Comprise steel pipe 1, pre-load nut 2, spring perch 3, spring 4, supporting seat 5, bolt 6, sleeve 7 and travel switch 8; It is characterized in that: an end of described bolt 6 links to each other with steel pipe 1, pre-load nut 2 through screw thread; The other end links to each other with supporting seat 5 through the sleeve 7 of its outside, spring 4 between sleeve 7 and spring perch 3 and with bolt 6 sockets, travel switch 8 links to each other with supporting seat 5 through screw thread and is positioned at the below of bolt 6.
The beneficial effect of the utility model is:
1, owing on supporting seat, be provided with two cover travel switches, no matter which position steel rope arrives along cylinder axis direction sway, and travel switch can both move exactly when slack rope takes place, and realizes safety arrestment effectively thereby promote function.
2, because supporting seat has kidney slot, travel switch installation site and steel rope location gap are adjustable up and down, have solved between the two to cause frequent safety arrestment parking apart from too small, even the also difficult situation that makes the travel switch action of the excessive appearance slack rope of spacing.
3, through the screw-in of pre-load nut on bolt or the amount of compression of back-out adjustable springs, thus thereby can be according to steel rope all compression stroke switch realization mine hoist safety brakings effectively when slack rope occurring of different unit weights.
The realization of above-mentioned beneficial effect has guaranteed that this rope creep protection device does not receive the influence of steel rope run location, steel rope unit weight and elevation angle, when the slack rope state occurring, all can effectively realize safety arrestment, has guaranteed the safe in operation of mine hoist.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side-looking structural representation of Fig. 1.
Among the figure: 1---steel pipe, 2---pre-load nut, 3---spring perch, the 4-spring, 5---supporting seat, 6---bolt, 7---sleeve, 8---travel switch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are done further explain.
Referring to accompanying drawing; A kind of mine hoist is used the rope creep protection device; Comprise steel pipe 1, pre-load nut 2, spring perch 3, spring 4, supporting seat 5, bolt 6, sleeve 7 and travel switch 8, it is characterized in that: an end of described bolt 6 links to each other with steel pipe 1, pre-load nut 2 through screw thread, and the other end links to each other with supporting seat 5 through the sleeve 7 of its outside; Spring 4 between sleeve 7 and spring perch 3 and with bolt 6 sockets, travel switch 8 links to each other with supporting seat 5 through screw thread and is positioned at the below of bolt 6.
Adjust the spacing of steel rope and travel switch 8 and the pre compressed magnitude of spring 4 according to the unit weight and the run location of steel rope in advance; When the slack rope situation occurring; Sagging steel rope forces steel pipe 1 to move vertically downward through its deadweight; Screw rod 6 is descending along the axial direction of sleeve 7, compression stroke switch 8.Travel switch normally closed contact disconnection this moment safety return circuit makes gig carry out safety arrestment.
At the bracing frame two ends travel switch is installed all, pre-load nut and spring is set is convenient to regulate compressive force, travel switch is offered the distance that kidney slot is convenient to regulate steel rope and travel switch, realizes the safe operation of mine hoist.
