Abstract

The utility model relates to an endless rope winch for sublevel continuous drafters in mine auxiliary transportation. A motor and a speed reducer are arranged on one side of a base along the length direction of the base, and a rope roll is arranged beside the motor and the speed reducer. A speed reducing gear pair is arranged between the rope roll and an output shaft of the speed reducer, and the output shaft of the speed reducer is in a shaft sheathing type connection with a shaft of a small gear. A big gear is arranged on a shaft of the rope roll and is fixedly connected with the rope roll; both ends of the shaft of the small gear and the rope roll are provided with bearing seats fixed on the base. The utility model has the advantages of small ground occupation, convenient installation and movement, and good integral performance.

Description

Endless rope winch

The utility model relates to the endless rope winch of the gate continuous towing vehicle system that is used for mining assistant conveyance.

Crossheading traction continuously is a kind of transportation device that utilizes the operation of rope traction car team, and endless rope winch is the propulsion source of gate continuous towing vehicle system.Endless rope winch has base, on its base, be arranged in order directly or indirectly and base bonded assembly motor, reductor, transmission gear, barrel, wherein motor is laid sidewards, make the integral structure of winch looser like this, floor area is bigger, all brings difficulty for the installation of winch, resettlement.

The purpose of this utility model is to propose the stepless rope winch of a kind of reasonable integral structure, compactness.

Technical solution adopted in the utility model is that motor and reductor are arranged on base one side along the base length direction, barrel is arranged on the side of motor and reductor, be provided with a pair of speed reducing gear pair between barrel axle and speed reducer output shaft, speed reducer output shaft is a hollow shaft, pinion shaft is plugged in the hollow shaft, and connects with key, and big gear wheel is arranged on the barrel axle, and captive joint with barrel, pinion shaft, barrel axle two ends are equipped with the bearing seat that is fixed on the base.

Above-mentioned barrel axle is on the base length line of centers.

The coupler of above-mentioned connection motor and reductor is provided with the power hydraulic pressure pusher brake.

The grooving cross sectional shape of above-mentioned barrel is parabola shaped.

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 is that the utility model pinion shaft is connected diagrammatic sketch with speed reducer output shaft.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 and shown in Figure 2, the utlity model has base 1, at base in a side, be provided with explosion separation motor 2 and reductor 5 along its length, adopt resilient pin coupler 3 to be connected between motor shaft and reductor input shaft, promptly each fixes a terminal pad on diaxon, with several nylon pin pin joints, this coupler has certain buffer action between two dishes.Be provided with hand-driven belt type brake 6 on reductor, this is a kind of common drg, and power hydraulic pressure pusher brake 4 is set on coupler, and embodiment adopts the YWZ series power hydraulic pressure pusher brake that supply is arranged on the market.Be provided with barrel 14 at the side of motor and reductor and on the base length line of centers, 7 of barrel axle 2 and speed reducer output shafts are provided with a pair of gear pair 11,10, pinion shaft 9 is connected (see figure 2) with the cover shaft type that is connected to of speed reducer output shaft 7, be that speed reducer output shaft 7 is hollow shaft, pinion shaft 9 is plugged in the hollow shaft, and connect with key 15, big gear wheel 11 is fastened on the barrel axle 12 by key, and by being threaded and barrel 14 is fixed together, grooving 16 cross sectional shapes of barrel are parabola shaped.The pinion shaft two ends respectively are provided with the bearing seat 8 that is fixed on the base, and in fact pinion shaft forms three point support, promptly the diaxon bearing and and speed reducer output shaft between point of connection, barrel axle two ends are provided with the bearing seat 13 that is fixed on the base equally.

The utility model is owing to a side setting of taking motor and reductor along base, barrel is arranged on the side of motor and reductor, and pinion shaft adopts the cover shaft type to be connected with speed reducer output shaft, omitted coupler, make compact overall structure, the size of base narrows down to 2.4M * 1.5M from original 3.5M * 1.8M, and floor area greatly reduces, and gives and installs, moves and bring great convenience; Barrel is symmetrical in the setting of base length line of centers, steel rope can both be drawn in two ends, can select being installed on the 180 degree directions of winch according to field working conditions, provide certain convenience to installation, make the holding-down bolt of base stressed evenly simultaneously, avoid base phenomenon to take place to lift up because of unbalance stress; The utility model has increased the power hydraulic pressure pusher brake that can declutch automatically with the start-stop of motor, descends lock except hand brake, improved the safety performance of tractor truck.The three point support of pinion shaft, the rigidity and the vibration resistance of pinion shaft have been improved, the grooving cross sectional shape of barrel adopts parabolic type, has guaranteed that the phenomenon of steel rope effusion grooving can not take place the two-way rotation of barrel, and these all make the overall performance of product increase.
