Abstract
The utility model discloses a push away jack device from anchor formula for push away the bridge roof beam body, jack and track to setting up including the level, the one end of jack is fixed with reaction frame fixed connection, the other end with fixing the supporting shoe fixed connection of bridge roof beam body afterbody, reaction frame fixed mounting be in on the track. The utility model has the advantages that: the self-anchored jacking jack device not only enables the track of the bridge to roll smoothly and has small impact force in the jacking process, but also has simple device structure and good effect of realizing quick and continuous jacking.
Description
Technical Field
The utility model relates to a bridge thrustor, concretely relates to from anchor type top and push away jack device.
Background
At present, the well-known bridge mainly relates to construction working conditions such as crossing roads, riverways, railways and the like, and mainly adopts a dragging or walking type pushing erection construction process.
Wherein, the dragging construction speed is fast, but the impact force is generated and the stability is not stable. The walking type pushing construction cost is high, the equipment is more and complex, and the speed is slow.
Disclosure of Invention
The utility model aims at providing a from anchor top pushing jack device according to the weak point of above-mentioned prior art, the device sets up jack and reaction frame through the bridge girder body afterbody on the track to realize the gentle roll of bridge girder body on the track and push away in succession.
The utility model discloses the purpose is realized accomplishing by following technical scheme:
a self-anchored jacking jack device is used for jacking a bridge body and is characterized by comprising jacks and a track, wherein the jacks are horizontally arranged, one end of each jack is fixedly connected with a reaction frame, the other end of each jack is fixedly connected with a supporting block fixed at the tail of the bridge body, and the reaction frames are fixedly arranged on the track.
The bridge beam body is erected on a sliding frame, and the sliding frame is installed on the track in a matched mode.
The reaction frame is fixedly connected with the track through steel pins, and a plurality of pin holes for the steel pins to be inserted are preset on the track at intervals.
The top head of the jack is fixedly connected with the reaction frame, and the base of the jack is fixedly connected with the supporting block.
The top head of the jack is fixedly connected with the supporting block, and the base of the jack is fixedly connected with the reaction frame.
The reaction frame is triangle-shaped, is in including bottom plate and riser and the setting that mutually perpendicular set up the bottom plate with a plurality of vertical stiffening rib of saying between the riser.
The utility model has the advantages that: the self-anchored jacking jack device not only enables the track of the bridge to roll smoothly and has small impact force in the jacking process, but also has simple device structure and good effect of realizing quick and continuous jacking.

Fig. 1 is a schematic structural view of a self-anchored jacking jack device in an initial state of the present invention;
fig. 2 is a schematic view of the self-anchored jacking jack device for jacking up the middle part to the maximum stroke of the present invention;
fig. 3 is a schematic view of the jack driving the reaction frame to retract after the middle pushing of the utility model is completed.
Detailed Description
The features of the present invention and other related features are described in further detail below by way of example with reference to the accompanying drawings, for the understanding of those skilled in the art:
referring to fig. 1-3, the symbols in the figures are: the bridge comprises a bridge body 1, supporting blocks 2, a sliding frame 3, a jack 4, a reaction frame 5, a steel pin 6 and a track 7.
Example (b): as shown in fig. 1, 2, and 3, the present embodiment specifically relates to a self-anchored jacking jack device, which is used for jacking and pushing a bridge beam body 1 on a track 7, and mainly includes a jack 4 and a reaction frame 5, where the jack 4 is horizontally erected (i.e., arranged parallel to the track 7), a head of the jack 4 is fixedly connected to the reaction frame 5, a base of the jack 4 is fixedly connected to a support block 2 at a tail end of the bridge beam body 1, the bridge beam body 1 is erected on a sliding frame 3, and the sliding frame 3 is specifically a roller device, and can form rolling friction on the track 7 to reduce jacking resistance of the bridge beam body 1, and under the jacking drive of the jack 4, the bridge beam body 1 can roll forward along with the sliding frame 3, so as to realize continuous and smooth jacking of the bridge beam body 1.
As shown in fig. 1, 2 and 3, the reaction frame 5 in this embodiment is in a triangular shape, and includes a bottom plate, a vertical plate and a longitudinal stiffening rib, the bottom plate is horizontally disposed close to the track 7, the vertical plate is welded and fixed to the bottom plate, and a plurality of longitudinal stiffening ribs are disposed between the bottom plate and the vertical plate. It should be noted that a plurality of pin holes are preset at intervals on the rail 7, and the reaction frame 5 is inserted into the pin holes on the rail 7 through a plurality of steel pins 6, so as to realize the fixed connection with the rail 7, and provide a horizontal reaction force for the pushing of the jack 4.
As shown in fig. 1, 2 and 3, before the pushing operation, the steel pin 6 is inserted into the pin holes on the reaction frame 5 and the rail 7, so that the reaction frame 5 and the rail 7 are connected into a whole to provide a reaction point for the jack 4 to push, and the bridge body 1 is driven to move forwards by the jacking of the jack 4; and after the jack 4 is jacked to reach the maximum stroke, pulling out the steel pin 6 on the reaction frame 5, retracting the jack 4 to drive the reaction frame 5 to contract and move along with the jack 4 until the jack 4 contracts in place, fixing the reaction frame 5 and the track 7 through the steel pin 6 again, and continuing the next jacking process of the jack 4.
The beneficial effect of this embodiment lies in: the impact force in the bridge dragging construction process is reduced, the stability is enhanced, and the problems of low walking type pushing speed, more equipment and complexity are solved, so that the device has a simple structure, and the rapid and continuous pushing is realized.
