Abstract

The utility model relates to a kind of mining crane adding tightening device, comprising friction turn, steel rope, tractor truck, braking car, freight container and return rope sheave, described steel rope is connected to friction turn and forms operating loop with returning between rope sheave, tractor truck, braking car and freight container are installed on the up rope body of steel rope, the descending rope body that steel wire is strong is provided with and can makes steel rope and the close-connected tightening device of crane, described tightening device comprises large gyrostat, and be located at large gyrostat and friction turn respectively, return the little gyrostat between rope sheave, described large gyrostat is hung with counter weight device, the tightening device that this crane is set up is formed primarily of a large gyrostat and two little gyrostats, rub between itself and steel rope less, the degradation of energy caused is few, crane still can smooth working in transportation, the counter weight device be connected with large gyrostat can adjust with the relax level of steel rope, operates also more convenient, on the whole, the safety of crane transport improves greatly.

Description

A kind of mining crane adding tightening device
Technical field
The utility model relates to a kind of equipment transported for underground coal mine material, equipment and personnel, is more particularly a kind of mining crane adding tightening device.
Background technology
Mining crane is underground coal mine, in upper and lower mountain, exploiting field and driving surface gallery, be especially used for transporting one of the advanced accessory equipment of material, equipment and personnel.The track of crane is a kind of special I-beam section, and i-beam track is suspended on excavation support or builds on overarm, anchor pole and pre-buried chain.Material, equipment etc. are suspended in by carrying vehicle or lifting beam on the single track at top, tunnel by crane, drawn transport by the trailer coupling of crane.Crane transport haul distance is generally 1000 ~ 2000 m, and maximumly reach 3000 m, running velocity is: fortune people is l.5 ~ 2m/s; Haul and equipment are 2 ~ 2.5m/s, sometimes up to 4.5 m/s.Under the continual translocation of crane, haulage cable can relax in time, on the one hand conveying efficiency is reduced, on the other hand, brings potential safety hazard to production.
Utility model content
The purpose of this utility model is to provide a kind of mining crane adding tightening device, makes steel rope be in tensioning state all the time, and tensioning intensity is adjustable, avoids steel rope to endanger because using tired generation.
The purpose of this utility model is by realizing with under type: a kind of mining crane adding tightening device, comprising friction turn, steel rope, tractor truck, braking car, freight container and return rope sheave; Described steel rope is connected to friction turn and forms operating loop with returning between rope sheave, tractor truck, braking car and freight container are installed on the up rope body of steel rope, the descending rope body that steel wire is strong is provided with and can makes steel rope and the close-connected tightening device of crane, described tightening device comprises large gyrostat, and the little gyrostat be located at respectively between large gyrostat and friction turn, time rope sheave, described large gyrostat is hung with counter weight device.
Described little gyrostat is positioned on same level line.
Described counter weight device is weights, conveniently can regulate the tensioning intensity of large gyrostat.
The utility model compared with prior art has the following advantages: a kind of mining crane adding tightening device, the tightening device set up is formed primarily of a large gyrostat and two little gyrostats, rub between itself and steel rope less, the degradation of energy caused is few, and crane still can smooth working in transportation; The counter weight device be connected with large gyrostat can adjust with the relax level of steel rope, operates also more convenient; On the whole, the safety of crane transport improves greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation adding the mining crane of tightening device.
In figure, 1. friction turns, and 2. steel rope, 3. tractor truck 4. brake car, 5. freight container, 6. time rope sheave, 7. tightening device, the large gyrostat of 7-1., the little gyrostat of 7-2., 7-3. counter weight device.
Detailed description of the invention
In the accompanying drawings, a kind of mining crane adding tightening device, comprising friction turn 1, steel rope 2, tractor truck 3, braking car 4, freight container 5 and return rope sheave 6; Described steel rope 2 is connected to friction turn and forms operating loop between 1 and time rope sheave 6, tractor truck 3, braking car 4 and freight container 5 are installed on the up rope body of steel rope 2, the descending rope body of steel wire strong 2 is provided with and can makes steel rope 2 and the close-connected tightening device 7 of crane, described tightening device 7 comprises large gyrostat 7-1, and be located at large gyrostat 7-1 respectively and friction turns 1, returns little gyrostat 7-2 between rope sheave 6, described large gyrostat 7-1 is hung with counter weight device 7-3.
Described little gyrostat 7-2 is positioned on same level line.
Described counter weight device 7-3 is weights, conveniently can regulate the tensioning intensity of large gyrostat 7-1.
This crane mainly relies on adhesion to drive, under tightening device 7 acts on, and steel rope 2 and crane each several part compact siro spinning technology, then drive steel rope 2 to run by the friction force that steel rope 2 and friction turn 1, return rope sheave 6, thus traction crane is along track crank motion.Can by the intensity regulating weights to regulate tensioning.
