Abstract
The utility model discloses a mechanical rope adjusting device. The mechanical rope adjusting device comprises a lead screw, an adjusting nut, a spring, a spring base, a wheel frame and a sliding wheel, wherein the spring is sleeved above the lead screw, the spring base is sleeved outside the spring, the wheel frame is fixedly arranged below the lead screw through a rivet, and the sliding wheel is fixedly arranged in the middle of the wheel frame through a pin shaft. The mechanical rope adjusting device can enable the length of a steel wire rope to be conveniently adjusted, the steel wire rope is better tensioned, a weight is lifted steadily, and meanwhile the mechanical rope adjusting device can play a good role in buffering to impact force.
Description
Technical field
The utility model relates to a kind of being installed on the derrick in small mine, be used for the rope regulator of trustworthy rope, check band tension.
Background technology
Country is for small-sized mine poor management before, a lot of mines are voluntarily to steady rope tension, adopt various forms, modal tension is to lead chain one of crown installation steady rope is strained, even this tension mode is passable for the steady rope of tension, but, but there is very big potential safety hazard for anti-fall rope.Catch device moment when catching anti-fall rope when catching, steel rope is had very big impact, leading chain is steel chain, is easy to break under the effect of impulsive force.
The utility model content
The purpose of this utility model is to overcome above deficiency a kind of mechanical rope regulator is provided, and can conveniently adjust length of steel wire rope, and have buffer action, reduces the potential safety hazard in the use, increases the service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mechanical rope regulator comprises the screw mandrel that is arranged on the crossbeam, is arranged with spring on the screw mandrel on crossbeam top, and the screw mandrel at spring top is provided with adjustment nut, and the screw mandrel end of crossbeam bottom is provided with wheel carrier, and pulley is installed in the wheel carrier.
Described spring overcoat is provided with spring perch, and the bottom of spring perch is contained on the crossbeam.
Described pulley is fixed in the middle of the wheel carrier by bearing pin.
Adopt technique scheme, the utility model has following advantage: after steel rope long-term use elongation, adjustment nut is tightened spring downwards, can adjust length of steel wire rope once more, make connection cage steel rope all around be in identical tension all the time, keep the balance of cage in lifting process; Break when main rope, catch and catch device when catching check band, the rope regulator spring can play buffer action, reduces potential safety hazard.
Description of drawings
Fig. 1 is the structural representation of the utility model machinery rope regulator.
The specific embodiment
Mechanical rope regulator as shown in Figure 1 comprises the screw mandrel 1 that is arranged on the crossbeam 7, is arranged with spring 3 on the screw mandrel on crossbeam top, and the screw mandrel at spring 3 tops is provided with adjustment nut 2, and the screw mandrel end of crossbeam bottom is provided with wheel carrier 5, and pulley 6 is installed in the wheel carrier 5.Be arranged with spring perch 4 outside spring 3, the bottom of spring perch 4 is contained on the crossbeam 7.Pulley 6 is fixed in the middle of the wheel carrier 5 by bearing pin.
Mechanical rope regulator is installed on the derrick, adjustment nut 2 is tightened spring 3 downwards can make steel rope be in identical tension, guarantee can not swing when weight promotes, make the steady lifting of weight, after using a period of time, steel rope has stretching in various degree, tightens adjustment nut 2 tense wire rope very easily; Break when main rope, catch and catch device when catching check band, spring 3 can play buffer action, reduces the impulsive force of weight to mechanical rope regulator, reduces potential safety hazard, and increases the service life.
