Description
Technical field
The utility model is specifically related to a kind of prestressed stretch-draw support, belongs to prestressing technique field, building site.
Background technology
In highway, the construction of railroad bridge post stressed concrete, can run into many situations needing presstressed reinforcing steel, wherein, presstressed reinforcing steel is mostly heat tempering bar, steel wire, steel strand.And for installation ground tackle and tensioning equipment: when ground tackle and tensioning equipment are installed, to straight-line prestressed muscle, the position of tension force and duct center line should be made to overlap in stretching process; To curved prestressing tendon, the tangent line of the position of stretching force and cell ends central point should be made to overlap.Therefore, the various situation to stressing equipment requirement for height and angle requirement can be run in construction at the scene.
Adopt scaffold temporarily assembled with regard to prestressed stretch-draw support majority in current stressing equipment, or adopt i iron to be welded into Hanging Basket, make it react on wing plate, keep balance.But this device not only weighs, and operation, mobile very inconvenient, and jack can not horizontal slip, and can easily not adjust according to the length of the muscle to be tensioned exposing beam-ends, stretch-draw efficiency comparison is low.
Summary of the invention
For the problems referred to above, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, uses flexibly, can carry out the prestressed stretch-draw support of position adjustment according to the length of muscle to be tensioned.
Prestressed stretch-draw support of the present utility model, comprises base plate; Described base plate is fixedly installed the first hydraulically extensible bar group; Described first hydraulically extensible bar group upper end is fixedly installed gripper shoe; Symmetrically arranged rail groove before and after described support plate upper surface offers; Symmetrically arranged support side plate before and after being provided with above described gripper shoe; Described support side plate is fixedly linked by upper connecting rod and lower link; Described support side plate arranged outside has roller; Described roller is by being movably connected through the rotating shaft in support side plate and support side plate; Described roller is arranged in rail groove; Described support side plate left end is fixedly linked by the second hydraulically extensible bar group and gripper shoe; In the middle part of described upper connecting rod, below is welded with hook; Described hook is mounted with the jack for stretch-draw muscle by cable wire; On the left of described base plate, top is fixedly installed hydraulic means; Described first hydraulically extensible bar group is all connected with hydraulic means by hydraulic tube with the second hydraulically extensible bar group.
Further, described first hydraulically extensible bar group is made up of four hydraulically extensible bars.
Further, described rail groove is provided with two.
Further, described support side plate is " A " font.
The utility model beneficial effect: a kind of structure of the present utility model is simple, uses flexibly, can carry out the prestressed stretch-draw support of position adjustment according to the length of muscle to be tensioned; When using the utility model, muscle to be tensioned is fixed on the jack of stretch-draw muscle; The utility model operationally, controls the flexible of the first hydraulically extensible bar group and the second hydraulically extensible bar group by hydraulic means, by the height of the flexible adjustable support plate of the first hydraulically extensible bar group, thus adjusts the height of jack; Stretching by the second hydraulically extensible bar group, makes support side plate and roller move left and right on rail groove, thus changes the right position of jack; The utility model can change the position of jack by the control of hydraulic means to the first hydraulically extensible bar group and the second hydraulically extensible bar group to such an extent as to adapt to the muscle to be tensioned of different length, therefore have and use the advantage flexible, the scope of application is wide, indirectly can improve the efficiency of tension of prestressed tendon simultaneously.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is right TV structure schematic diagram of the present utility model.
Detailed description of the invention
Prestressed stretch-draw support as depicted in figs. 1 and 2, comprises base plate 1; Described base plate 1 is fixedly installed the first hydraulically extensible bar group 2; Described first hydraulically extensible bar group 2 upper end is fixedly installed gripper shoe 3; Symmetrically arranged rail groove 4 before and after described gripper shoe 3 upper surface offers; Symmetrically arranged support side plate 5 before and after being provided with above described gripper shoe 3; Described support side plate 5 is fixedly linked by upper connecting rod 6 and lower link 7; Described support side plate 5 arranged outside has roller 9; Described roller 9 is by being movably connected through the rotating shaft 8 in support side plate 5 with support side plate 5; Described roller 9 is arranged in rail groove 4; Described support side plate 5 left end is fixedly linked with gripper shoe 3 by the second hydraulically extensible bar group 10; In the middle part of described upper connecting rod 6, below is welded with hook 11; Described hook 11 is mounted with the jack 13 for stretch-draw muscle by cable wire 12; On the left of described base plate 1, top is fixedly installed hydraulic means 14; Described first hydraulically extensible bar group 2 is all connected with hydraulic means 14 by hydraulic tube (not shown) with the second hydraulically extensible bar group 10; Described first hydraulically extensible bar group 2 is made up of four hydraulically extensible bars; Described rail groove 4 is provided with two; Described support side plate 5 is " A " font.
When using the utility model, muscle to be tensioned is fixed on the jack of stretch-draw muscle; The utility model operationally, controls the flexible of the first hydraulically extensible bar group and the second hydraulically extensible bar group by hydraulic means, by the height of the flexible adjustable support plate of the first hydraulically extensible bar group, thus adjusts the height of jack; Stretching by the second hydraulically extensible bar group, makes support side plate and roller move left and right on rail groove, thus changes the right position of jack.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
