Abstract
The utility model belongs to the building trade, build large-span hoist and mount beam structure specifically says so. Aiming at the problem that the large-span stage for building open celebration and entertainment performance in the prior art cannot solve, the structure adopting the diagonal draw rope and the counterweight is designed, and the structure is composed of a cross beam, a support column, a reinforcing rope and an electric hoist; the inclined pulling rope passes through a pulley arranged at the upper part of the supporting column. Has the advantages of reasonable design and simple structure; the construction of the large-span hoisting beam structure becomes practical. Can be widely popularized and applied in the construction of large-span stages for grand celebration and great performance.
Description
Technical field
The utility model belongs to building trade, is specifically to build large span lifting girder construction.
Background technology
The stage that activities such as common outdoor celebration, open-air performance are built, owing to be subjected to the restriction of factors such as structure, the length of stage is the longest to be reached about 30 meters; Growing along with national economy, grand celebration activity with day increase, grand variety show requires increasingly to stage, has become building trade a great problem anxious to be solved and build the large span stage.
The utility model content
The purpose of this utility model is to build the difficult problem that the large span stage exists at prior art, has designed a kind of new construction, adds the oblique rope rope at lifting roof beam structure two ends, and sets the mass that is complementary, so that construction large span stage is become a reality.
Large span lifting girder construction is to be made of crossbeam, support column, reinforcing rope and electric each parts of calabash stove, it is characterized in that the crossbeam two ends are provided with the oblique rope rope, the oblique rope rope other end is the pulley of installing through support column top, is linked to be movable whole by counterweight rope and mass and electric calabash stove.
Good effect of the present utility model is, adopts the mounting means of tradition lifting beam, and the load of crossbeam is all born by the lifting rope by lifting electricity calabash stove, and after crossbeam lifted on the support column, when crossbeam during greater than 30 meters, crossbeam easily produced amount of deflection, and the waist phenomenon occurs collapsing; This structure is at the crossbeam two ends oblique rope rope to be set, the load of crossbeam is except that lifting rope burden, the oblique rope rope that mass is installed also participates in bearing the load on the crossbeam, it is more laborsaving to make that the lifting rope promotes crossbeam, and, because of the oblique rope rope that mass is installed is arranged on the crossbeam, crossbeam does not have amount of deflection and produces; Along with the increase of crossbeam span, the increase of loading, crossbeam is equipped with the oblique rope rope can make span reach 40m length or longer, also can't realize in any case this is traditional hoisting structure mode.

The specific embodiment
To structure of the present utility model and action mechanism, specifically be explained as follows in conjunction with the accompanying drawings:
The utility model sees also Fig. 1, it is to be made of crossbeam, support column, reinforcing rope and electric each parts of calabash stove, crossbeam 5 two ends are provided with oblique rope rope 7, and the pulley 4,10 that oblique rope rope 7 is installed through support column 12 tops is linked to be movable whole by counterweight rope 11 and mass 1 and electric calabash stove 2.
During operation, earlier support column 12 is highly built up on request, and the electric calabash stove of lifting crossbeam and oblique rope rope 7 pulley 4,10 by its slideway is installed on support column 12 tops, the crossbeam 5 usefulness lifting ropes of then assembling being finished 8 are fixing, and with the other end by pulley 4,10, the oblique rope rope 7 that electric calabash stove 2 and mass 1 are installed is fixed on the crossbeam both ends; Start in the hoisting process, not only the lifting rope of crossbeam lifting electricity calabash stove is born crossbeam load, and the oblique rope rope is also born crossbeam load respectively, and like this, the electric calabash stove load that promotes crossbeam can reduce greatly, and lifting is more prone in place; Oblique rope rope 7 is equipped with electric calabash stove 2 and mass 1 by pulley 4,10, the oblique pulling of oblique rope rope 7 makes crossbeam eliminate the possibility that produces amount of deflection, and owing to the oblique rope rope 7 of mass 1 by slideway is fixed on the crossbeam, so, when the load on the crossbeam 5 changed, the autoregulation that mass 1 possesses can make crossbeam remain normal condition.Behind crossbeam 5 hoisted in position, further fixing with reinforcing rope 3 and 6.
When the crossbeam span is big, when weighing load increased, the crossbeam two ends were established two respectively, perhaps three to four oblique rope ropes 7, and respectively at the other end setting electric calabash stove 2 and the mass 1 separately of oblique rope rope 7.
Claims (2)
1. large span lifting girder construction is by crossbeam (5), support column (12), reinforces each parts formation of rope (3), (6) and electric calabash stove (2), it is characterized in that crossbeam (5) two ends are provided with oblique rope rope (7), oblique rope rope (7) other end is provided with electric calabash stove (2) and mass (1).
2. large span lifting girder construction according to claim 1, it is characterized in that it is pulley (4), (10) of installing through support column (12) top that crossbeam (5) is gone up the oblique rope rope (7) that is provided with, and is linked to be movable whole by counterweight rope (11) and mass (1) and electric calabash stove (2).
