The technical solution adopted in the utility model is to provide a kind of rope sheave with self-locking device, comprises runner, steel rope, bracing frame, also comprises self-locking mechanism on bracing frame, described steel wire penetrating self-locking mechanism; Described self-locking mechanism comprises U-shaped adapter plate, roller; The biside plate of described U-shaped adapter plate has a pair of long slot bore on identical position; Described roller is provided with the gear teeth, and roller shaft is fixed with wheel shaft in the heart; Described wheel shaft two ends and described a pair of long slot bore bearing fit; Angle between at the bottom of the U-lag of the length direction of described a pair of long slot bore and U-shaped adapter plate is acute angle, and the minimum clearance between at the bottom of the gear teeth of roller and U-lag is less than the diameter of steel rope.
Preferably, with the rope sheave of self-locking device, described acute angle is between 15 ° to 45 ° angles.
Preferably, with the rope sheave of self-locking device, on described wheel shaft, be also provided with spanner.
Preferably, with the rope sheave of self-locking device, support frame as described above is provided with hook.
The beneficial effect that the utility model produces is while using rope sheave with self-locking device to transport up and down instrument and material, the steel wire penetrating self-locking mechanism of rope sheave, the runner of self-locking mechanism because friction force along with steel rope rotates, when steel rope moves downward, runner also moves downward, and steel rope is locked.Can prevent like this that misoperation or steel rope from breaking causes weight to fall, injure operating personnel and preparation of construction, and, by the spanner on manual control runner, can also effectively Steel wire rope lock be fixed on to optional position, the instrument and the material that facilitate staff to take off to transport, improved work efficiency, reduced security risk.Can be widely used in the machineries such as fixed pulley or capstan winch, strand roller, winch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model roller;
Fig. 3 is the structural representation of the utility model embodiment 2.
In figure, 1 hook, 2 bracing frames, 3 runners, 4 steel ropes, 5U shape adapter plate, 6 long slot bores, 7, roller, 8 rotating shafts, 9 spanners.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
Shown in Fig. 1 embodiment, with the rope sheave of self-locking device, comprise on runner 3, steel rope 4, bracing frame 2, bracing frame 2 and also comprise self-locking mechanism, described steel rope 4 is through self-locking mechanism.
Further explain the present embodiment, because rope sheave is fixed, thus on rope sheave, install self-locking mechanism additional, directly that the bracing frame of self-locking mechanism and rope sheave 2 is fixing, the steel rope of rope sheave 4 is passed from self-locking mechanism.The beneficial effect producing is like this, after rope sheave and self-locking mechanism are secured together, to facilitate carrying of whole body of tool, and, in the process of rope sheave reeve 4 also through self-locking mechanism, threading repeatedly in installation process.The object that installs self-locking mechanism on rope sheave additional is to prevent steel rope 4 tenesmus that meets accident, and causes falling accident, and, installing self-locking mechanism additional can also, when needed by steel rope 4 lockings, make weight remain on certain height, convenient working personnel's operation, save manpower, increase work efficiency.
As Fig. 1, in this enforcement, with the rope sheave of self-locking device, described self-locking mechanism comprises U-shaped adapter plate 5, roller 7; The biside plate of described U-shaped adapter plate 5 has a pair of long slot bore 6 on identical position; Described roller 7 is provided with the gear teeth, and roller is fixed with wheel shaft 8 on 7 axle center; Described wheel shaft 8 two ends and described a pair of long slot bore 6 bearing fits; Angle between at the bottom of the length direction of described a pair of long slot bore 6 and the U-lag of U-shaped adapter plate 5 is acute angle, and the minimum clearance between at the bottom of the gear teeth of roller 7 and U-lag is less than the diameter of steel rope 4; Described acute angle is between 15 ° to 45 ° angles.
Further explain the present embodiment, this self-locking mechanism, on U-shaped adapter plate 5, install the roller 7 with the gear teeth additional, roller 7 contacts with steel rope 4, when steel rope 4 upward movement, roller 7 is because of friction force also upwards rotation, due to the length direction of long slot bore 6 and the bottom land of U-shaped adapter plate 5 in a certain angle, this angle is between 15 ° to 45 °, when steel rope 4 moves downward, roller 7 also moves downward, and extruded cords rope 4, and the object that roller 7 is provided with the gear teeth is the friction force increasing steel rope 4.While declining due to steel rope 4, be subject to friction force effect, stop declining, be so just locked in self-locking mechanism.The beneficial effect that the present embodiment produces is that roller 7 is followed the motion of steel rope 4 and rotates, and when steel rope 4 declines, steel rope 4 is locked rapidly, and the reaction time is fast, and braking effect is strong.
As Fig. 1, with the rope sheave of self-locking device, on described wheel shaft 8, be also provided with spanner 9.
The beneficial effect of the present embodiment is, in the time need to removing self-locking mechanism to the locking of steel rope 4, rotary spanner 9, turns to roller 7 top of long slot bore 6, removes the extruding of 7 pairs of steel ropes 4 of pair roller.And the beneficial effect of the present embodiment also comprises: when operating personnel initiatively locks steel rope 4, rotary spanner 9, forwards roller 7 to long slot bore 6 belows, initiatively, by steel rope 4 lockings, will more accurately weight be fixed on to certain height like this.
As Fig. 1, with the rope sheave of self-locking device, on support frame as described above 2, be also provided with hook 1.The effect of hook 1 is can make to be used as and surely to change wheel use with the rope sheave of self-locking device.
Embodiment 2
Self-locking mechanism as shown in Figure 3, the difference of the present embodiment and embodiment 1 is that described self-locking mechanism comprises two rollers 7, two pairs of long slot bores 6.
Further explain the present embodiment: in the present embodiment, the structure of self-locking mechanism is different with the self-locking mechanism of embodiment 1, adopt two rollers, 7 friction and extruded cords ropes 4, when steel rope 4 declines, two rollers 7 decline simultaneously, from both direction, push Locking stylet rope 4 simultaneously, like this steel rope 4 decline very little distance just can be locked, the beneficial effect of the present embodiment be can be more accurately Locking stylet rope rapidly, increase work efficiency, ensure operating personnel's safety.
