Description
Technical Field
The utility model relates to the field of valves, in particular to a working table frame device of bridge prestressed tendon tensioning equipment.
Background
At present, with the rapid development of road construction, the proportion of bridges in the road construction is larger and larger. The precast beam is more widely applied to bridge design, most beam bodies need to be subjected to prestress tensioning, and the tensioning engineering quantity of each beam field is larger. In the current tensioning operation construction process, a prestressed jack is often used for tensioning, and because the prestressed jack is heavy in quality, a simple support frame and a chain block are often adopted as a lifting system to lift and install the prestressed jack, the position adjustment operation is very complicated, the material and labor cost are increased in the construction process, the mounting quality and efficiency of the prestressed jack are not high, and great potential safety hazards exist.

Drawings
FIG. 1 is a perspective view of the structure of the present invention;
FIG. 2 is another state diagram of FIG. 1;
in the figure: the device comprises a frame-shaped support frame 1, universal wheels 2, a sliding chute 3, a sliding frame 4, a winch 5, a steel wire rope 6, a prestress jack 7, a sliding wheel 8, a sliding rope 9 and a rocking handle 10.
Detailed Description
The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:
as shown in fig. 1 and 2, a bridge prestressed tendon tensioning equipment workbench device comprises a frame type support frame 1 with an open front end, sliding grooves 3 are formed in two sides of the top of the frame type support frame 1, sliding grooves 4 are formed in the sliding grooves 3 and are connected with a sliding frame 4 in a sliding mode, a winch 5 is fixed to the top of the sliding frame 4, a steel wire rope 6 end of the winch 5 is fixedly arranged on a prestressed jack 7 on the inner side of the frame type support frame 1, a pulley mechanism used for pulling the sliding frame 4 to move back and forth is arranged on the upper portion of the frame type support frame 1, the pulley mechanism comprises a sliding wheel 8 arranged at the top of the front end and the rear end of the frame type support frame 1, a sliding rope 9 is arranged on the sliding wheel 8 in a penetrating mode, and two ends of the sliding rope 9 are fixedly connected with two sides of the sliding frame 4 respectively.
A rocking handle 10 is fixed on one side of the sliding wheel 8, and the rocking handle 10 is arranged on the other side of the open end of the frame-shaped support frame 1.
The universal wheel 2 arranged at the bottom of the frame-shaped support frame 1 is arranged by adopting a self-locking universal wheel.
The working principle is as follows: when a reinforcing steel bar anchor cable bundle on a box girder is tensioned by using a prestress jack 7, firstly, the prestress jack 7 is fixed at the end of a steel wire rope 6 of a winch 5, a frame-shaped support frame 1 is pushed to rapidly move through a universal wheel 2 at the lower part, when an opening at the front end of the frame-shaped support frame 1 is opposite to the reinforcing steel bar anchor cable bundle of the box girder to a certain distance in the moving process, the prestress jack 7 is kept opposite to the reinforcing steel bar anchor cable bundle at the horizontal position, and the universal wheel 2 is locked to fix the frame-shaped support frame 1;
after the hoisting machine 5 is fixed, the prestressed jack 7 at the lower part of the hoisting machine 5 is adjusted to be at the height position, so that the prestressed jack 7 is over against the box girder steel bar anchor cable bundle in height, after the height position is adjusted, the rocking handle 10 is held to drive the sliding wheel 8 to drive the sliding frame 4 at the lower part of the hoisting machine 5 to move on the sliding groove 3 through the sliding rope 9, the adjustment of the front and back positions of the hoisting machine 5 and the prestressed jack 7 at the lower part thereof can be realized, the adjustment of the distance between the prestressed jack 7 and the steel bar anchor cable bundle is realized, after the distance is adjusted, the prestressed jack 7 is installed on the over-against steel bar anchor cable bundle, so that the prestressed jack is consistent with the steel bar anchor cable bundle in position when being installed, the installation precision and the installation efficiency are greatly improved, the operation is simple and flexible, the transportation of the prestressed jack is convenient, and the labor cost is greatly saved, and the lifting and fixing safety of the prestress jack 7 is greatly improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
