Background technology
The power plant mainly towing machine of elevator, specifically comprises electrical motor, drg, coupler, drop-gear box, traction sheave and frame.Wherein, traction sheave also claims traction rope sheave or drives rope sheave, is the device that elevator transmits traction power, utilizes the friction force transferring power of grooving on traction steel-cable and traction wheel rim, be contained on the worm-wheel shaft in retarder.The usual one end of hoist ropes is fixed on elevator counterweight, and the other end is fixed on car, is realized the lifting of elevator by forward and reverse rotation of traction sheave.Multi-rope friction hoisting form is a kind of form usually adopted, and has hoisting capacity large, the advantage that degree of safety is high.But due to independent mutually between each hoist ropes, after using a period of time, there is difference in suffered Tensity size, affects elevator safety.At present, usually respectively nut and recoil spring are arranged to each hoist ropes, regulated stressed by rotating nut, reach the stress balance between each hoist ropes, often need to regulate multiple nut just can be effective, very inconvenient, accommodation accuracy is also not easy to control simultaneously, affects elevator stability and safety.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of structure simple, automatically regulate, degree of balance is high, the tension-adjusting gear of the elevator rope of good stability.
For achieving the above object, the technical solution used in the present invention is: a kind of tension-adjusting gear of elevator rope, described hoist ropes is more than two or two, tension-adjusting gear comprises the rope bar that connect corresponding to described each hoist ropes, be located at the hydraulic actuating cylinder of described each rope bar free end and the hydraulic pipe being communicated with each hydraulic actuating cylinder, it is characterized in that: described hydraulic pipe gets back to first hydraulic actuating cylinder be communicated with all the other each hydraulic actuating cylinders successively from first hydraulic actuating cylinder after, form C/LOOP.
In a preferred embodiment of the present invention, comprise described each hydraulic actuating cylinder cross section further and be parallel to each other and be parallel to the C/LOOP plane of described hydraulic pipe.
In a preferred embodiment of the present invention, the cross-wise direction comprising described whole rope bar is further provided with the positioning plate limiting each rope bar longitudinal movement.
In a preferred embodiment of the present invention, comprise described each rope bar further through each spacing hole on described positioning plate, rope bar and spacing hole's one_to_one corresponding, and the shape of every root rope bar arbitrary cross section is identical, and consistent with corresponding spacing hole's shape, be polygon.
In a preferred embodiment of the present invention, comprise further on described each rope bar and be arranged with recoil spring between positioning plate and hydraulic actuating cylinder.
In a preferred embodiment of the present invention, comprise described each rope bar cross-sectional plane further and corresponding spacing hole's shape is regular hexagon.
In a preferred embodiment of the present invention, comprise described hydraulic actuating cylinder is fixed on longitudinal extension fixed support by horizontal fixed link further, described limiting bracket is also fixed on described fixed support.
The invention solves the defect existed in background technology, the tension-adjusting gear of elevator rope of the present invention adopts the hydraulic actuating cylinder being communicated with into closed-loop to regulate and to balance each hoist ropes stressed, automatic adjustment replaces manual regulation, convenient, formation closed-loop is conducive to liquid in hydraulic actuating cylinder and better flows, and improves balance.Polygon can be arranged in rope bar cross section and corresponding spacing hole's profile, be conducive to preventing from hoist ropes work, being with running rope bar to produce bad twisting, affect stressed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1-2, the tension-adjusting gear of a kind of elevator rope of the present invention, described hoist ropes 1 is 5-6 root, is arranged in a straight line.Tension-adjusting gear comprises the rope bar 2 that connect corresponding to described each hoist ropes 1, is located at the hydraulic actuating cylinder 4 of described each rope bar 2 free end and the hydraulic pipe 6 being communicated with each hydraulic actuating cylinder 4.The cross-wise direction of described whole rope bar 2 is provided with the positioning plate 8 limiting each rope bar 2 longitudinal movement, each rope bar 2 is through each spacing hole 81 on described positioning plate 8, rope bar 2 and spacing hole 81 one_to_one corresponding, and the shape of every root rope bar 2 arbitrary cross section is identical, and it is consistent with corresponding spacing hole 81 shape, for regular hexagon, size, the shape of described each spacing hole 81 are also identical.Each rope bar 2 is arranged with recoil spring 10 between positioning plate 81 and hydraulic actuating cylinder 4, the effect of damping can be played corresponding rope bar 2 and hoist ropes 1.Recoil spring 10 cross-sectional outer diameter is less than hydraulic actuating cylinder 4 diameter of section, is greater than spacing hole 81 internal diameter.Described hydraulic pipe 6 gets back to first hydraulic actuating cylinder 4 from first hydraulic actuating cylinder 4 after relative position is from the close-by examples to those far off communicated with all the other each hydraulic actuating cylinders 4 successively, forms C/LOOP.Described each hydraulic actuating cylinder 4 be parallel to each other and arbitrary hydraulic actuating cylinder 4 cross-section parallel in the C/LOOP plane of described hydraulic pipe 6.Described tension-adjusting gear also comprises the fixed support 12 of a longitudinal extension, and described hydraulic actuating cylinder 4 is fixed on this fixed support 12 by horizontal fixed link 14, and described positioning plate 8 is also fixed on this fixed support 12.
Be installed on by tension-adjusting gear of the present invention on elevator rope 1, after elevator work a period of time, some hoist ropes 1 are stressed to change, and breaks the balance between original hoist ropes 1.Liquid now in hydraulic actuating cylinder 4 forms C/LOOP owing to being communicated with by hydraulic pipe 6, and liquid can free-flowing, automatically regulates the pressure of each hydraulic actuating cylinder 4, makes to reach balance, namely adjust the stress balance of each hoist ropes 1.It is circular that rope bar 2 cross section is different from tradition, but regular hexagon design, effectively prevent rope bar 2 and hoist ropes 1 from twisting, affect stress balance and hoist ropes life-span.The C/LOOP in-plane of described hydraulic pipe 6, concentrates on side because hydraulic actuating cylinder 4 is arranged in a row, and may cause steady in this direction of hydraulic actuating cylinder 4 and hydraulic pipe 6, arrange fixed link 14 and hydraulic actuating cylinder 4 is fixed on fixed support 12, can strengthen its balance.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to right.
