Abstract
The invention relates to a hanging bracket for pouring bridges and cantilevers, in particular to an electric hanging bracket with a traveling right-handed wheel. The hanging bracket adopts the right-handed pressing wheel machine traveling mode and is driven by an electric winch. A traveling device comprises one or more right-handed pressing wheel machines. The right-handed pressing wheel machinesare connected with anchor rods embedded on the bridge deck by connectors. Rollers of the right-handed pressing wheel machines are welded in a chute on the hanging bracket and roll but not move along with the hanging bracket. A set of electric winches and a set of angle pulley blocks are respectively arranged on each of two longitudinal girders of the hanging bracket to serve as drive systems for moving the hanging bracket. The hanging bracket does not need to balance weights, does not need traveling tracks and features lighter dead weight, lower cost, easy and simple operation, low labor intensity and high efficiency.
Description
Technical field
The present invention relates to a kind of bridge cantilever pouring Hanging Basket, especially do not have balance ballast Hanging Basket.
Background technology
Firm structure of prestressed concrete or continuous girder bridge adopt the cast-in-place method of sections sections ground cantilever to construct, and each sections links up by reinforcing bar and prestressing force steel hinge line.Cantilever pouring concrete and prestress engineering all carry out on Hanging Basket.After a sections was finished, Hanging Basket needed cantilever running to arrive the continuation construction of next position, and so circulation is carried out, until last sections.
The cantilever pouring Hanging Basket adopts the Hanging Basket of no balance ballast at present mostly, under the situation particularly big in bridge span, that wind load is big, in order to alleviate the weight of Hanging Basket, can only adopt the Hanging Basket of no balance ballast to carry out cantilever construction.Hanging Basket needs cantilever and the load of playing is walked to walk to next position and continued operation after finishing the building of a beam section, therefore, during the Hanging Basket walking, the problem of must solution toppling forward.At present, the left-hand thread wheel mode is all adopted in the walking of known no balance ballast Hanging Basket, and the left-hand thread wheel is connected the Hanging Basket rear end and fastens the edge of a wing that is anchored at the track on the bridge floor.During the Hanging Basket walking, the left-hand thread wheel moves and fastens the edge of a wing of track and topples to prevent Hanging Basket with Hanging Basket, and behind stroke of traveling, the track of the back of dismantling is installed on it the place ahead again and walks on for Hanging Basket.This left-hand thread wheel mode, track must be arranged, this track is very heavy, not only need the transportation that manufactures and designs of the time-consuming expense material of taking a lot of work to install, and dismounting and transporting repeatedly also in the course of the work, every installation once all will be jack-uped Hanging Basket heavy walking road can be filled in Hanging Basket longeron below, and labour intensity is big, speed is low, but also has unsafe factor.The type of drive of existing Hanging Basket has hydraulic pressure, electronic and manual mode, but all takes turns away line mode at left-hand thread.
Summary of the invention
In order to overcome the deficiency of above-mentioned Hanging Basket, the invention provides a kind of electric hanging bracket with traveling right-handed wheel.This Hanging Basket adopts electric winch to drive, and right hand thread pinch rollers is adopted in walking, need not the balance ballast, also need not the track of walking.
The present invention is achieved by the following technical programs: cover electric winch and an angle pulley group respectively is set, the drive system that moves as Hanging Basket on two longerons of Hanging Basket.
The present invention also is achieved by the following technical programs: running gear comprises one or more right hand thread pinch rollers.Right hand thread pinch rollers is connected with embedded anchor bar on being embedded in bridge floor with connector, rolls in the chute of the roller of right hand thread pinch rollers on being welded in Hanging Basket but does not move with Hanging Basket.
The invention has the beneficial effects as follows:
● Hanging Basket need not the balance ballast, also need not walking rails, conduct oneself with dignity lighter, cost is lower, and is easy and simple to handle, labour intensity is low, efficient is high.
● electric winch and assembly pulley are the standing instrument equipment of unit in charge of construction, and Hanging Basket drives and adopts hoist system, can improve utilization rate of equipment and installations; Hoist engine and assembly pulley also are the standard devices of using always, purchase convenient and swift, even the therefore also very easy acquisition of cash purchase.

Component part numbers among the figure is as follows:
1-Hanging Basket spandrel girder;
2-Running System (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5): 21-right hand thread pinch rollers, 22-chute, 23-bridge floor embedded anchor bar, 24-cushion block, 211-anchor pole, 212-nut, 213-backing plate, 214-bearing pin; The 215-balancing stand, 216-turning rolls, 217-roller, 218-connector;
3-drives system (Fig. 1, Fig. 2): 31-electric winch, 32-angle pulley group; The pre-buried anchor ring of 33-;
4-hangs system.
The specific embodiment
Hanging Basket mainly is made up of spandrel girder (1), Running System (2), driving system (3), suspension system (4) and anchor device.Drive system (3) and Running System (2) and be used for driving the Hanging Basket walking, and the overturning moment of balance Hanging Basket when walking.The overturning moment of Hanging Basket when cantilever pouring come balance with anchor device.
Drive (3) (Fig. 1, the Fig. 2) of system and form, angle pulley group (32) is used for Hanging Basket position counteragent when accurately adjusting by hoist engine (31), angle pulley group (32) and pre-buried anchor ring (33).Driving system (3) has two cover drive units, is installed on respectively on two longerons.
Running System (2) (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5) is made up of some right hand thread pinch rollers (21), chute (22), bridge floor embedded anchor bar (23) and cushion block (24), pressing wheel device (21) is connected on the bridge floor embedded anchor bar (23) with connector, the roller of pressing wheel device (21) rolls in chute (22), chute is welded on the longeron of Hanging Basket, when Hanging Basket moves, the Hanging Basket longeron is gone up at cushion block (24) and is slided, chute (22) moves with Hanging Basket, and the roller of pressing wheel device (21) rolls in chute (22).When drive unit drove the Hanging Basket walking, right hand thread pinch rollers (21) was rolled on the Hanging Basket longeron but is not moved.After Hanging Basket walking puts in place and finishes a beam section construction of bridge, take being connected of embedded anchor bar (23) on right hand thread pinch rollers (21) and the bridge apart, carry out next working cycles.Embedded anchor bar (23) can replace with bridge vertical prestressing reinforcing bar, also can adopt the fining twisted steel reinforcing bar to be embedded in bridge floor in advance.
