Abstract
The utility model relates to a mounting structure with double car top sheaves of a lift. The mounting structure comprises vertical upper beam boards which are symmetrical and parallel with each other; transverse upper beam boards are symmetrically mounted on the lower end faces of the vertical upper beam boards in parallel; U-shaped bolts are fixedly connected with the both ends of each transverse upper beam board; and a car top sheave rotating shaft with each car top sheave is arranged between each two U-shaped bolts. The mounting structure provided by the utility has the advantages of simple structure and convenience in installation, and can not only maintain the stability of a lift car in a drawing process, but also shorten a transverse distance between a traction sheave and a diversion sheave of an engine room, so that the traction force is improved, and the lift can smoothly and stably run.
Description
Technical field
The utility model relates to the lift facility field, the mounting structure of the two crosshead sheaves of especially a kind of elevator.
Background technology
In the elevator design field, the depth size of lift car has determined whether the towing machine traction is up to standard, when car depth is excessive, as shown in Figure 1, the wrap angle of elevator dragging wire rope 104 on traction sheave 101 diminishes, and is prone to the situation that traction sheave can't draw lift car; The method of common increase traction is as follows:
(1) increase the weight of lift car self, but the weight that improves lift car can increase cost of manufacture;
(2) increase traction by increasing wrap angle, as shown in Figure 1, the method that increases wrap angle is two: shorten traction sheave 101 and 102 transverse distance L1 of machine room diversion sheave or increase above-mentioned fore-and-aft distance L2 between the two; The fore-and-aft distance that increases by 102 of traction sheave 101 and machine room diversion sheaves need to be by increasing the height of base of traction machine, and the method requires high to machine room height, also increased design cost and building cost simultaneously.If adopt the words that shorten traction sheave 101 and 102 transverse distance L1 of machine room diversion sheave, need to change the installation site (upper beam assembly not shown) of sedan-chair top diversion sheave 103 on upper beam assembly, change its installation site so that sedan-chair top diversion sheave 103 can't be positioned at the middle part of upper beam assembly, easily cause the unsettled situation of elevator cage operation.
The utility model content
The applicant is for the problems referred to above, and the mounting structure of the two crosshead sheaves of a kind of elevator is provided, and has simple in structurely, easy for installation, effectively raises the advantage of elevator traction power.
The technical scheme that the utility model adopts is as follows:
The mounting structure of the two crosshead sheaves of a kind of elevator, comprise the vertically upper beam slab that Parallel Symmetric arranges, transversely the beam slab Parallel Symmetric is installed on the lower surface of vertically upper beam slab, and transversely the two ends of beam slab affixed " U " shape bolt installs the crosshead sheave rotating shaft with crosshead sheave between two " U " shape bolt.
It is further characterized in that:
Described vertically upper beam slab reaches transversely, and beam slab is " C " shape channel-section steel;
The affixed boots plate of leading in two ends of described vertically upper beam slab upper surface, the transversely affixed connecting panel in the two ends of beam slab.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, stationarity when the mounting structure of the two crosshead sheaves of employing has not only kept the lift car traction, shortened simultaneously the transverse distance between traction sheave and the machine room diversion sheave, thereby increased the cornerite of steel rope on traction sheave, improved traction, make elevator can be smoothly, the pulsation-free operation, solved the problem that has in the past increased design cost and building cost.
Description of drawings
Fig. 1 is the application drawing of existing crosshead sheave.
Fig. 2 is front view of the present utility model.
Fig. 3 is the lateral plan of Fig. 2.
Fig. 4 is the upward view of Fig. 3.
Fig. 5 is application drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 2, the utility model comprises the vertically upper beam slab 4 that Parallel Symmetric arranges, and transversely beam slab 7 Parallel Symmetrics are installed on the lower surface of vertically upper beam slab 4, vertically go up beam slab 4 and reaches transversely that beam slab 7 is " C " shape channel-section steel.As shown in Figure 3, Figure 4, transversely 5 devices of the two ends of beam slab 7 affixed " U " shape bolts 5, two " U " shape bolt are with the crosshead sheave rotating shaft 8 of crosshead sheave 1, and as shown in Figure 1, and it is fixing to pass through nut 6, prevents that the rotating shaft 8 of crosshead sheave 1 from dropping, loosening.Such as Fig. 2, shown in Figure 3, the in the vertical affixed boots plate 2 of leading in the two ends of beam slab 4 upper surfaces, the transversely affixed connecting panel 3 in the two ends of beam slab 7.
As shown in Figure 5, owing to adopt the mounting structure of two crosshead sheaves, changed the installation site of towing machine, shorten traction sheave 101 and 102 transverse distance L1 of machine room diversion sheave, thereby increased the wrap angle of steel rope on traction sheave, improved traction, make elevator can be smoothly, the pulsation-free operation, solved the problem that in the past increases design cost and building cost.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of basic structure of the present utility model, the utility model can be done any type of modification.
