Abstract

The utility model discloses a rear counterweight of a goods lift free of a machine room. The rear counterweight of the goods lift free of the small machine room comprises a traction wheel (1), a counterweight wheel (2), a car bottom wheel (3), a car (4), a guide wheel (5), a lateral guide wheel (6), a car door (7), a counterweight body (8) and a traction rope (9). The car bottom wheel (3) is arranged at the bottom of the car (4). The car door (7) is arranged in the front of the car (4). The counterweight wheel (2) is arranged above the counterweight body (8) and is arranged in the rear of the car (4) along with the counterweight body (8). One side of the traction rope (9) starts from the traction wheel (1), passes by the car bottom wheel (3) and the lateral guide wheel (6) and arrives at a fixation point (M) of the traction rope and the other side of the traction rope (9) passes by the guide wheel (5), the counterweight wheel (2) and the lateral guide wheel (6) and arrives at a fixation point (N) of the traction rope. Compared with the prior art, the width of the car and the car door is maximized as possible. The rear counterweight of the goods lift of the small machine room runs stably and is widely applied to goods lifts free of machine rooms.

Description

The rear counterweight of machine room cargo lift

Technical field

The utility model belongs to the elevator field, relates in particular to the traction system of cargo lift, specifically, relates to the counterweight of machine room cargo lift.

Background technology

For the machine room cargo lift, all be the side counterweight usually, adopt sedan-chair return pulley wiring, so that desired hoistway headroom height is minimum when main frame is put.As shown in Figure 1, a kind of known solution for machine room cargo lift side counterweight, it comprises roller 2, sedan-chair return pulley 3, car 4, car door 7, pair weight 8, sedan-chair return pulley 3 is typically provided with 4 and all be positioned at the bottom of car 4, there are 2 also to form counterweight system for elevators with the pair weight 8 that is positioned under it to roller 2, car door 7 is arranged on the front side of car 4, and roller 2 and pair weight 8 are positioned at the left side of car 4, namely forms so-called side counterweight.The design's weak point is: when the elevator hoistways width is restricted, and require simultaneously car width larger, and when car is monolateral opening the door, the side counterweight will tie up this with regard to narrow and small width spaces, so that car and car door can't wide as far as possible settings, out of reach user's psychological needs weaken the competitiveness of product in market.

The utility model content

For the weak point of current techniques, the utility model is special to propose a kind of rear counterweight of new machine room cargo lift, and it can not only address the deficiencies of the prior art, and also has other many useful effects.

The rear counterweight of machine room cargo lift, comprise traction sheave 1, to roller 2, sedan-chair return pulley 3, car 4, track adjusting wheel 5, side guide wheel 6, car door 7, pair weight 8, hoist ropes 9, described sedan-chair return pulley 3 is positioned at the bottom of described car 4, described car door 7 is arranged on the front side of described car 4, described roller 2 is positioned at described pair weight 8 tops, the two forms counterweight system for elevator, the described rear side that roller 2 and described pair weight 8 is positioned at described car 4; Described hoist ropes 9 one sides from traction sheave 1 via sedan-chair return pulley 3 and side guide wheel 6 to hoist ropes attachment point M, opposite side from traction sheave 1 via track adjusting wheel 5, to roller 2, side guide wheel 6 to hoist ropes attachment point N.

Above-mentioned listed each member is the common configuration of elevator, and its structure function does not describe in detail at this.Need to prove, so-called car door, it namely is usually alleged elevator door, it is the passage that passenger or goods enter lift car, we are defined as the front side of car its position, and its position that faces, and are exactly the rear side of car, and here, the set position of the utility model counterweight system just.

In order to make whole traction system running smooth, usually, sedan-chair return pulley 3 is provided with 4, one group in twos, and all be distributed in four jiaos of places, bottom of car 4, because the sedan-chair return pulley is positioned at rear and front end at the bottom of the sedan-chair, in cargo handing, because the effect of hoist ropes is led boots to the application force of guide rail in the time of can significantly alleviating because of cabin uneven loading.

Because above-mentioned setting, make the utility model realize its goal of the invention, its beneficial effect is: when (1) is restricted when the elevator hoistways width, and require simultaneously car width larger, and when car is monolateral opening the door, rear counterweight will can not tie up this with regard to narrow and small width spaces, so that car and car door obtain wide as far as possible setting, reach user's psychological needs, improve the competitiveness of product in market; (2) operate steadily.Sedan-chair return pulley 3 is provided with 4, and all is distributed in four jiaos of places, bottom of car 4, in cargo handing, because the effect of hoist ropes is led boots to the application force of guide rail in the time of can significantly alleviating because of cabin uneven loading.

Because above-mentioned beneficial effect, the utility model is widely used in the machine room cargo lift, especially the large-tonnage cargo lift.

The specific embodiment

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

As shown in Figure 2, the rear counterweight of machine room cargo lift, it comprises roller 2, sedan-chair return pulley 3, car 4, car door 7, pair weight 8, sedan-chair return pulley 3 is provided with 4 and all be positioned at four jiaos of places, bottom of car 4, there are 2 also to form counterweight system for elevators with the pair weight 8 that is positioned under it to roller 2, car door 7 is arranged on the front side of car 4, and roller 2 and pair weight 8 are positioned at the rear side of car 4, namely forms so-called rear counterweight.So-called car door namely is usually alleged elevator door, is the passage that passenger or goods enter lift car, and we are defined as the front side of car its position, and the position of its car opposite side that faces, and are exactly the rear side of car.

As shown in Figure 3, be the winding structure scheme drawing of a kind of embodiment of the utility model.It comprises traction sheave 1, to roller 2, sedan-chair return pulley 3, car 4, track adjusting wheel 5, side guide wheel 6, car door 7, pair weight 8, hoist ropes 9.Described sedan-chair return pulley 3 is provided with 4, namely forms so-called 4 to 1 tracting structures, they one group in twos, all be positioned at four jiaos of places, bottom (bottom surface of car is usually rectangular) of described car 4.Described car door 7 is arranged on the front side of described car 4, is the passage that passenger or goods enter car.Described roller 2 is positioned at described pair weight 8 tops, the two forms counterweight system for elevator, in order to make the elevator operation more steady, is 2 to the number of roller 2, is symmetrically distributed in the top of pair weight 8.Roller 2 and described pair weight 8 are positioned at the rear side of described car 4; Described hoist ropes 9 one sides from traction sheave 1 via sedan-chair return pulley 3 and side guide wheel 6 to hoist ropes attachment point M, opposite side from traction sheave 1 via track adjusting wheel 5, to roller 2, side guide wheel 6 to hoist ropes attachment point N.
