Description

Walking pushing device

The technical field is as follows: the invention relates to an application occasion of pushing of a variable-section bridge, in particular to a pusher device capable of transversely and automatically transversely moving a bridge.

Background art: at present, in continuous bridge pushing construction, a walking type pushing machine is adopted for pushing operation, the self structural characteristics of a bridge are that the transverse bridge direction linearity is constant in width, and the width of a stress web position of the bridge is constant. Once the structure of the bridge is designed to be of a variable cross section, the transverse width of the stressed web position of the bridge changes along with the pushing process, and at the moment, a walking type pushing machine and temporary support are required to move transversely along with the web position. The walking type pushing machine and the temporary support move transversely on the temporary pier due to the fact that the weight of the single body is large, high-altitude operation is achieved, large-scale operation equipment cannot enter the temporary pier to participate in work, manual transverse movement is difficult to achieve, when the transverse movement distance is large, the requirement for the using amount of the transverse moving beam at the bottom is very large, the requirement for temporary measures of site construction is very large, project cost is very high, and economy is poor. Because the walking type pushing machine and the temporary support are used for respectively carrying out stress support on the bridge, if the transverse moving is carried out in a manual mode or a pulled gourd mode on site, the overall efficiency is low, and the operation intensity is high.

The invention content is as follows:

aiming at the defects in the prior art, the invention aims to provide a walking thruster, which not only solves the transverse self-translation function of the thruster, but also realizes the stress concentration of jacking.

In order to achieve the purpose, the invention adopts the following technical scheme:

the walking pushing device comprises the following components: a carrying pole beam, a walking type pushing machine, a transverse moving beam, a pushing machine base and a transverse moving oil cylinder. The carrying pole beam is used as a temporary support in the pushing process of the bridge, and the walking type pushing machine is used for jacking, pushing and rectifying the deviation of the bridge. The transverse beam can bear the load of the upper part and can be used as a transverse track of the walking pushing device. The pushing machine base is used for placing the walking pushing machine, and the pushing oil cylinder is installed on the pushing machine base through screws. When the position of a web plate of the bridge changes in the transverse knocking direction, the whole equipment needs to move transversely, the walking type pushing machine can be emptied at the moment, the whole stress of the bridge is transferred to the stress of the carrying beam, the transverse moving oil cylinder controls the direction through the reversing valve, and the oil cylinder can drive the bottom plate of the whole pushing machine and the walking type pushing machine to move together because the carrying beam is pressed by the bridge at the moment and the transverse moving cannot be generated due to the movement of the transverse moving oil cylinder. When the transverse moving oil cylinder moves in place by one stroke, the walking type pushing machine is jacked to bear force, the carrying pole beam is emptied, the transverse moving oil cylinder is loaded by reverse force, and the oil cylinder can drive the carrying pole beam to transversely move because the walking type pushing machine is pressed by the bridge and cannot transversely move.

When the carrying pole beam is pressed, the front and rear stress points of the carrying pole beam are transmitted to the middle transverse beam through the carrying pole beam, so that the transverse beam of the walking thruster and the transverse beam of the carrying pole beam are the same.

The walking type pushing machine can realize the integral jacking, pushing and deviation rectifying of the bridge and the future beam falling. All walking thrusters are uniformly controlled by a computer, and all actions can be realized by a control room.

The transverse moving beam realizes the stressed support of the walking type pushing machine and the carrying beam and realizes the transverse movement of the walking type pushing machine and the carrying beam.

The pushing machine base is used for supporting the walking pushing machine and realizing the transverse moving support of the walking pushing machine.

The transverse moving oil cylinder is used for realizing transverse moving of the walking type pushing machine and transverse moving of the carrying pole beam.

The device of the invention has the following beneficial effects:

1) the transverse movement of the walking type pushing machine and the carrying pole beam is automatically realized;

2) the design of the shoulder beam reduces the construction strength requirement of the temporary pier and saves the use requirement of the transverse beam;

3) the use of the transverse moving oil cylinder effectively reduces the requirement on the labor intensity of workers.
