Abstract

The utility model relates to a straight elevator restraining-corner upper-lower-beam structure, which comprises a compartment, an elevator upper beam, an elevator lower beam and a counterweight device, wherein the compartment and the counterweight device are arranged in a shaftway, the elevator upper beam and the elevator lower beam are respectively fixed on the top and the bottom of the compartment, four corners of the elevator upper beam and those of the elevator lower beam are in a restraining relationship, so that two ends of the elevator upper beam and those of the elevator lower beam are in a splayed shape, and the counterweight device is arranged on a position which is close to the outer side of the compartment; and through the technical scheme, under the situation that the design requirements of a diversion sheave, a traction sheave and a counterweight diversion sheave are met in the shaftway, the design of the compartment and the counterweight is more compact and reasonable, and the arrangement of the counterweight device can be closer to the compartment, so that a large shaftway space can be saved, the utilization rate of the shaftway is increased, the construction cost of a building can be reduced.

Description

Up and down, craspedodrome elevator gram angle girder construction

Technical field

The utility model relates to the craspedodrome elevator, particularly relates to up and down, a kind of craspedodrome elevator gram angle girder construction.

Background technology

in the prior art, as depicted in figs. 1 and 2, on the elevator of craspedodrome elevator, underbeam is all to adopt the steel plate bending mode, bending forms as shown in Figure 3, the lift crosshead structure of craspedodrome elevator and the structure of elevator underbeam are basic identical, as shown in Figure 4, car top arranges diversion sheave, be provided with traction sheave and counterweight diversion sheave on the right of diversion sheave, described diversion sheave, traction sheave and counterweight diversion sheave, the center line edge coincidence of these three rope sheaves, position relationship between car and counterweight is followed this principle, and require the certain safety distance of underbeam maintenance on counterweight and car and elevator, along with the growing tension of living space, in saving building as far as possible, usable floor area can bring the saving on very large cost.

The utility model content

In view of this, the technical problems to be solved in the utility model is to provide up and down, a kind of craspedodrome elevator gram angle girder construction, pass through the technical program, make in hoistway can be more near car to rearrangement, thereby saved the hoistway space of bulk, promote the degree of utilization of hoistway, reduced the cost of building.

For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that up and down, a kind of craspedodrome elevator gram angle girder construction, comprise underbeam and counterweight on car, elevator, described car and counterweight are arranged in hoistway, on elevator, underbeam is separately fixed at the top of car and the bottom of car, on described elevator, the Si Jiaochu of underbeam is the gram horn shape, makes that on elevator, the underbeam two ends are splayed, and described counterweight is arranged on the position in neighbour's car outside.

The technique effect that utility model reaches is as follows: up and down, a kind of craspedodrome elevator gram angle girder construction, pass through the technical program, make under the designing requirement of hoistway internal satisfaction diversion sheave, traction sheave and counterweight diversion sheave, the compact and reasonable more of car and counterweight design, the layout of counterweight can be more near car, thereby saved the hoistway space of bulk, promoted the degree of utilization of hoistway, reduced the cost of building.

Description of drawings

Fig. 1 is the plan structure figure of underbeam on elevator in prior art.

Fig. 2 is the front elevation of Fig. 1.

Fig. 3 is the lateral plan of Fig. 1.

Fig. 4 is the section drawing in hoistway in prior art.

Fig. 5 is the section drawing in hoistway in the utility model.

In figure, underbeam, 2 cars, 3 diversion sheaves, 4 traction sheaves, 5 counterweight diversion sheaves, 6 gram horn shapes, 7 counterweights, 8 hoistways, 9 hoistway space of saving on 1 elevator.

The specific embodiment

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

As shown in Figure 5, up and down, the craspedodrome elevator gram angle girder construction that the utility model relates to, comprise underbeam 1 and counterweight 7 on car 2, elevator, described car 2 and counterweight 7 are arranged in hoistway 8, on elevator, underbeam 1 is separately fixed at the top of car 2 and the bottom of car 2, on described elevator, the Si Jiaochu of underbeam 1 is gram horn shape 6, makes that on elevator, underbeam 1 two ends are splayed, and described counterweight 7 is arranged on the position in neighbour's car 2 outsides.

In the utility model, after the position of counterweight 7 changes, the diversion sheave 3, traction sheave 4 and counterweight diversion sheave 5 threes that are positioned at hoistway 8 will meet the requirement of center line edge coincidence, that is to say, be positioned at the counterweight diversion sheave 5 on counterweight 7, counterweight 7 to left dislocation when the car 2, a center line edge of center line edge on traction sheave 4 and counterweight diversion sheave 5 is coincided, counterweight 7 is after left dislocation, and the position of vacateing is the hoistway space 9 of saving.

In the utility model, elevator curb girder (not marking in accompanying drawing) is arranged on the both sides of car 2 for C type outward opening, the two ends up and down of elevator curb girder are connected with underbeam 1 on elevator respectively, when underbeam 1 carried out the gram angle on to elevator, maximum gram horn shape 6 was not to injure the elevator curb girder as principle.

The above is only preferred embodiment of the present utility model, is not be used to limiting protection domain of the present utility model.

Claims

1. up and down, craspedodrome elevator gram angle girder construction, comprise underbeam and counterweight on car, elevator, described car and counterweight are arranged in hoistway, on elevator, underbeam is separately fixed at the top of car and the bottom of car, it is characterized in that, on described elevator, the Si Jiaochu of underbeam is the gram horn shape, makes that on elevator, the underbeam two ends are splayed, and described counterweight is arranged on the position in neighbour's car outside.
