Abstract

The utility model relates to an elevator for construction. A combined device of floor stopping linkage self locking and preventing ropes breaking is arranged on the cage, which makes the functions of self locking and preventing ropes breaking of the cage more safe, the combined device is arranged at the lateral surface of the cage which has little possibility to be polluted and being convenient to be repaired. The cage adopts bilateral double rail type sliding guide rail, which overcomes the defect that the existing single rail type cage is easy to derail, and the stability of the cage is simultaneously enhanced. A balance weight is additionally arranged between the winding machine and the pulley block, the total load borne by the winding machine is lightened, the power required by the winding machine is reduced, and thereby, the electric energy is saved. The utility model is suitable for using in construction.

Description

Lift for building

The utility model relates to the elevator that a kind of building operation is used.

The anti-break rope device of the elevator that generally uses during building operation now; all be independent telescopic structure of installing, during wire cable rupture, support foot stretches out and is stuck on the horizon bar of derrick in action of the spring; make the unlikely tenesmus of cage, thereby play the breaking rope protecting effect.But this device is very serious to the destruction of derrick, and in case flexible support foot is stuck on the brace of derrick, whole cage will tilt and drop, and therefore, its anti-break rope design is incomplete.

In addition; have layer protection that stop of elevator now; many unlatchings by the lever gate; the drive transmission device rotates, and support foot stretches out and reaches the protection purpose, and this device is because the transmission device complex structure; big and the difficult control of journey error when making support foot flexible; in fact protect effect be difficult to guarantee, and the space of occupying during lever-type gate opening is big, has hindered material handling.And stop layer protection and be installed in the cage bottom, easily adhere to foul, maintenance is also inconvenient.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of building operation elevator that stops layer linkage self-locking and anti-break rope composite set that has is provided.

The purpose of this utility model reaches like this: load onto extension spring, anti-break rope steel rope, lever above cage; The cage side is installed touching lever, transmission shaft and support foot; The gate of cage adopts stacked movable type, and its outer appropriate location is provided with touching lever holder part, stops layer linkage self-locking and anti-break rope composite set thereby constitute.When cage stops layer, gate opening makes the support foot that is in the position lift to the level position and stretches into guide rail beam by linkage self-locking mechanism, makes cage be in self-locking state.When the cage hoist rope ruptures suddenly; the extension spring of cage top, suspension rod, lever, steel rope etc. produce chain reaction, and the pull-up support foot is to the level position and stretch into guide rail beam, and cage is bearing on the guide rail; prevented that cage from falling, played the anti-break rope protective effect.

Fig. 1 is a keystone configuration scheme drawing of the present utility model.

Fig. 2 is that cage of the present utility model stops layer linkage self-locking and anti-break rope composite set structural representation, and as Figure of abstract.

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model mainly comprises winch (1), steel rope (2), assembly pulley (3) and cage (4), total weight is less than the bob-weight (5) of cage weight on connecting between fixed pulley group and winch, the gross load that winch is born alleviates greatly, reduce the winch power demand, saved electric energy.When the steel rope between winch and the bob-weight ruptured suddenly, because the relative load-carrying of cage alleviates, the impulsive force that the anti-break rope device is born reduced greatly simultaneously, and the degree of tortuosity that derrick is subjected to also reduces greatly.

Cage is done lifting with two steel ropes (6) by assembly pulley, steel rope is housed on two parallel steel ropes pricks head (snap close) (7), like this, when arbitrary steel rope wherein broken, another just can bear up the weight of cage, avoids cage and bob-weight to fall.Be the stability and the minimizing derailing possibility of reinforcement cage, cage can adopt bilateral double rail type guide rail to slide, and the also corresponding setting of pulley promptly is housed near side (ns) angular position, cage both sides slides guide rail.

The side of cage (8) is contained in the touching lever (10) that links to each other with the cage side by transmission shaft (9), and support foot (11) is equipped with in the below of transmission shaft, and the latter links to each other with the cage side by a fulcrum, and its front end connects anti-break rope steel rope hypomere (12).There is spacing support slot (13) top.The installing of cage upper cross-beam is by extension spring (14), lever (15) and anti-break rope steel rope epimere (16), the two ends of lever are connected with hypomere (12), the epimere (16) of anti-break rope steel rope respectively, extension spring one end is fixed on the cage crossbeam, and the other end is connected with anti-break rope steel rope epimere (16).Under normal condition, anti-break rope steel rope epimere (16) is in tension, and extension spring is pulled up, and lever remains static.

When the suspension wire rope ruptures suddenly; suspension rod (17) falls; anti-break rope steel rope epimere (16) is loose rapidly; extension spring is because of the rapid homing of elastic reaction; drive the lever perk, stretch out (12) tensioning of anti-break rope steel rope hypomere and pull-up support foot to level position, and cage is bearing on the guide rail beam (18); prevent to fall, play the breaking rope protecting effect.

Cage gate (19) adopts stacked movable type, and its skin is equipped with touching lever holder part (20) in the outer part with on the corresponding appropriate location of touching lever.Gate is left behind and is closed, and touching lever is in initial condition by deadweight, and lever is static under the normal circumstances, and anti-break rope steel rope hypomere is in relaxed state.Support foot is in the bevelled initial condition because of no external force effect, and cage is done normal operation.When cage stops layer loading and unloading, gate upwardly opens, and touching lever holder part holds up touching lever, drives transmission shaft and rotates, and the projection on the transmission shaft (21) presses down the support foot rear end, makes the horizontal perk of its front end and stretches into guide rail beam, cage thereby be in self-locking state.Completed loading, the gate of leaving behind, touching lever holder part moves down thereupon, and touching lever loses depending on deadweight and replys initial condition, and support foot also tilts saggingly because of no external force effect, and cage can continue to move.

The utility model stops layer self-locking and the anti-break rope effect is safe and reliable.And overcome the shortcoming that cage easily derailed when monorail slided in the past, improved the stability of cage simultaneously yet, stopped a layer self-locking protecting device and be installed in the cage side, vulnerable to pollution is not easy to maintenance, uses when being suitable for building operation.
