Abstract
The invention relates to a construction hoist in a bridge tower cavity, which comprises a dragging device, a suspension cage, a guide rail rack, a counterweight and a counterweight guide rail, wherein the guide rail rack is mounted on the side, near to a bridge deck, in the bridge tower cavity; the suspension cage is mounted on the guide rail rack via a gear rack; the dragging device is mounted at the top of the guide rail rack, and drags and drives the suspension cage via a steel wire rope; the counterweight guide rail is mounted on the inner wall, corresponding to the moving track of the suspension cage, of the tower cavity; the counterweight is mounted on the counterweight guide rail and is connected with the dragging device through the steel wire rope; and an escape door is arranged at the top of a driving cab of the suspension cage. Through the adoption of the structure, the use of the hoist can be satisfied very well without the arrangement of a machine room; since the guide rail rack is mounted on the side, near the bridge deck, in the bridge tower cavity to serve as a track for the suspension cage of the construction hoist to move up and down, the problem that guide rails of common construction hoists and elevators are difficult to mount in the inner cavities of main towers of large-size and over-size bridges is avoided; and through the arrangement of the escape door, a driver in the driving cab can escape smoothly.
Description
Technical field
The present invention relates to a kind of elevator, particularly relate to the building hoist in a kind of bridge tower chamber, belong to elevator technology field.
Background technology
At present, the jacking equipment used in tower chamber on bridge is building hoist and elevator, because tower cavity space is narrow and small, particularly large-scale and extra-large bridge king-tower intracavity section not relates to by standard hoistway, thus cause the installation of building hoist or elevator very complicated, waste time and energy, cost is very high.In addition, in general in order to coordinate the use of elevator, all machine room can be configured, but space is too little in bridge main tower can not arrange machine room; In addition, construction elevator cage operator's compartment in the market does not all arrange escape door, only arranges the window for life-saving at cage top, and the goods stacked in cage when there is unforeseen circumstances may hinder the driver in operator's compartment to escape.
Summary of the invention
Technical matters to be solved by this invention is for the deficiencies in the prior art, provides building hoist in a kind of bridge tower chamber.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: building hoist in a kind of bridge tower chamber, comprise drag device, cage, guide rail bracket, counterweight and counter weight guide track, described guide rail bracket is arranged in bridge tower chamber by bridge floor side, described cage is arranged on described guide rail bracket by rack-and-gear, described drag device is arranged on guide rail bracket top, described drag device is by cage described in steel rope tractive driving, the tower cavity wall corresponding with described cage running orbit installs counter weight guide track, described counter weight guide track installs counterweight, described counterweight is connected with drag device by steel rope, the operator's compartment top of described cage is provided with escape door.
The invention has the beneficial effects as follows: structure of the present invention does not need to arrange the use that machine room is also well positioned to meet elevator; And guide rail bracket is arranged on by bridge floor side in bridge tower chamber, in this, as the track that construction elevator cage runs up and down, avoid general building hoist with elevator in the large-scale problem with mounting guide rail difficulty in extra-large bridge king-tower inner chamber; By arranging escape door, the driver in operator's compartment is escaped smoothly.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described escape door hinged with cage, is provided with handle inside relative another side; Described escape door inner surface is provided with waterproof and goes along with sb. to guard him layer.
The beneficial effect of above-mentioned further scheme is adopted to be: waterproof to be set and to go along with sb. to guard him layer and can prevent rainwater from entering in operator's compartment.
Further, protective fence is provided with bottom described guide rail bracket.
Further, described escape door is connected by closing appliance with cage.
The beneficial effect of above-mentioned further scheme is adopted to be: by arranging latching device, escape door and cage body to be locked completely, avoiding elevator and send noise in the process of moving.
Further, described closing appliance comprises stem stem, and stem stem outside is provided with contract plate, be flexibly connected between described stem stem with contract plate, contract plate is socketed in the outside of stem stem by a tubular structure, can along stem stem axial rotation, and described closing appliance is arranged on escape door and cage contact position.
The beneficial effect of above-mentioned further scheme is adopted to be: latching device adopts triangle wedge structure, can adjust the position of latching device and cage body contact point as required, effectively can eliminate the gap between escape door and doorframe, escape door effectively can be locked.
