Abstract
The utility model discloses a counterweight of a 4:1 small machine room freight elevator, which comprises a side guide wheel 1, counterweight wheels 2, a dragging wheel 3, a dragging rope 4 and a counterweight body 5, wherein the counterweight wheels 2 are vertically arranged; and the dragging wheel 3 goes in from the lower counterweight wheel 2 through the dragging rope 4, goes out from the side guide wheel 1 to the upper counterweight 2 and is connected to a fixed rope head. The utility model has the beneficial effects that the counterweight width can be minimized, and the device has great significance particularly for the condition which requires a car platform sill through door, and is more suitable for an elevator dragging the car platform sill through door.
Description
Technical field
The utility model belongs to the elevator field, relates in particular to the counterweight system of elevator, specifically, relates to the counterweight of 4:1 small room cargo lift.
Background technology
The Elevator weight sensor balanced system that also weighs, the radical function of this system is the relative equilibrium car weight, and the weight difference between car and counterweight is remained within the limit, guarantees that the traction transmission of elevator is normal.Because its importance, the design arrangement of counterweight also becomes one of key areas in the elevator system design.
For 4:1 small room cargo lift, because the inherent characteristics of himself, there are obviously difference in its counterweight and traditional elevator.Be called as name: the Elevator weight sensor device, the patent No. is: 97212450.0 Chinese patent, its counterweight mainly by counterweight frame, to pouring weight, lead boots, buffer head is formed.Have another name called and be called: a kind of novel elevator counterweight, the patent No. is: 200820224223.6 Chinese patent, its counterweight mainly is made up of framework, casing, weighting material.
Above-mentioned design-calculated deficiency is: be not suitable for 4:1 small room cargo lift, and design is complicated.
Summary of the invention
At the weak point of current techniques, special a kind of new counterweight design plan, the i.e. counterweight of 4:1 small room cargo lift of proposing of the utility model.
The counterweight of 4:1 small room cargo lift, it comprises side guide wheel 1, counterweight wheel 2, traction sheave 3, hoist ropes 4, counterweight body 5, described side guide wheel 1, counterweight wheel 2 and counterweight body 5 are formed the Elevator weight sensor system, described traction sheave 3 is connected with described Elevator weight sensor system by described hoist ropes 4, the number of counterweight wheel 2 is 2, and the two is vertical setting; Described traction sheave 3 is gone into from following counterweight wheel 2 by described hoist ropes 4, via side guide wheel 1, goes out and is connected to fixedly fag end to top counterweight wheel 2.
In order to realize goal of the invention of the present utility model, reach the small room elevator, traction sheave 3 of the present utility model is driven by permanent-magnet synchnorous gearless dragging machine, this permanent-magnet synchnorous gearless dragging machine is applied among the man lift usually, in Cargo Lift, especially do not use in the large-tonnage cargo lift, because of it belongs to the especially general purpose module among the man lift of elevator, so repeat no more, in this Figure of description, also do not illustrate.
The beneficial effects of the utility model are: because two wheels on the counterweight are vertically placed, because of the counterweight wheel with on the approaching same perpendicular line of heavy side machine room guide wheel, thereby the width dimensions that can make counterweight reduces to minimum, the width dimensions that reduces counterweight is significant, particularly requires the situation of car rear opening.
Because above-mentioned beneficial effect, the utility model is widely used in the 4:1 towed elevator, especially in the elevator that 4:1 traction car rear opening is arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Identifier declaration: 1-side guide wheel; 2--counterweight wheel; The 3--traction sheave; 4-hoist ropes; 5--counterweight body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the counterweight of 4:1 small room cargo lift, it comprises side guide wheel 1, counterweight wheel 2, traction sheave 3, hoist ropes 4, counterweight body 5, described side guide wheel 1, counterweight wheel 2 and counterweight body 5 are formed the Elevator weight sensor system, described traction sheave 3 is connected with described Elevator weight sensor system by described hoist ropes 4, the number of counterweight wheel 2 is 2, and the two is vertical setting; Described traction sheave 3 is gone into from following counterweight wheel 2 by described hoist ropes 4, via side guide wheel 1, goes out and is connected to fixedly fag end to top counterweight wheel 2.
The width of counterweight occupies the hoistway area, for the less elevator of car depth, the width dimensions that reduces counterweight is significant, particularly requires the situation of car rear opening, for realizing this goal, present embodiment the wheel arrangement of counterweight and machine room near on the same perpendicular line.This structure greatly reduces the width of counterweight, and for avoiding the mutual interference of rope, two wheels on the counterweight and a wheel diameter of machine room have nothing in common with each other.
Being similar among Fig. 1 " ground connection " sign be to be fixing fag end, be the general setting of all elevators, no longer detailed description.
The engine installation of traction system is that non-the present utility model main points do not illustrate among Fig. 1 for permanent-magnet synchnorous gearless dragging machine drives, and also no longer describes in detail.
About design advantage of the present utility model and use occasion, substantially ditto state bright, so repeat no more.
