Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1-3, a platform truck for installation of two lining reinforcing bars in tunnel construction comprises supporting part, longitudinal reinforcing bar installation department and arc reinforcing bar installation department.
Specifically, the supporting part comprises a plurality of longitudinally arranged door-shaped frames 1, and the door-shaped frames 1 are connected through longitudinal beams to form a steel frame. In order to facilitate walking, the bottom of the door-shaped frame 1 is provided with a walking wheel driven by a motor; in order to facilitate the operation, horizontal operation platforms 2 are arranged on the top and two sides of the door-shaped frame 1, and connecting crawling ladders 3 are installed between the adjacent horizontal operation platforms 2. In order to improve the stability of the steel frame, reinforcing inclined struts 4 are welded between the door-shaped frame 1 and the horizontal operating platform 2.
The longitudinal steel bar installation part comprises a plurality of arc-shaped rails welded on the outer side of the portal frame 1 correspondingly, each arc-shaped rail comprises a pair of inner rails 5.1 and outer rails 5.2 arranged along the cross section of the tunnel, and a sliding rod 5.3 is arranged between the inner rails 5.1 and the outer rails 5.2 in a sliding mode and serves as a first bracket. When the device is used, the longitudinal steel bars are placed on the corresponding sliding rods 5.3, and the sliding rods 5.3 are driven by the winch to enable the longitudinal steel bars to move in place along the arc-shaped rails. In order to improve the structural stability, longitudinal support rods are welded between the adjacent inner rails 5.1 and the adjacent outer rails 5.2.
Arc reinforcing bar installation department is including being located the arc steelframe 6 that steel frame is close to tunnel exit one end, and the bottom both ends of this arc steelframe 6 all link to each other with steel frame through horizontal rotating shaft, and above-mentioned horizontal rotating shaft sets up along tunnel cross section for arc steelframe 6 can be round horizontal rotating shaft 90 within range rotations between ground and tunnel cross section, thereby conveniently will place the arc reinforcing bar subaerial and shift to the steel frame outer fringe and carry out the ligature. In order to fix the arc-shaped steel bars conveniently, a plurality of radial steel plates 7 are uniformly welded on the outer side of the arc-shaped steel frame 6 to serve as second brackets. The radial steel plate 7 is provided with a plurality of grooves for clamping arc-shaped steel bars, generally, the grooves are divided into an upper groove 8.1 and a lower groove 8.2 which are arranged along the horizontal direction in order to match the outer arc-shaped steel bars and the inner arc-shaped steel bars used by the two lining steel bars, and the opening directions of the upper groove 8.1 and the lower groove 8.2 face the inner side of the tunnel. After the arc-shaped steel bars are turned in place along with the arc-shaped steel frame 6, the arc-shaped steel bars can be conveniently transferred to the steel frame from the radial steel plates 7 and then are pushed towards the inner side of the tunnel along the steel frame.
In addition, a winch for driving the sliding rod 5.3 and the arc-shaped steel frame 6 is also arranged at the top of the steel frame.
During the construction, place arc steelframe 6 upset subaerial earlier, with outside arc reinforcing bar joint in last recess 8.1, then lift arc steelframe 6 up through hoist engine wire rope, make it carry out 90 upsets, when arc steelframe 6 was located tunnel cross section position, pull out outside arc reinforcing bar from last recess 8.1 in to along steel framework to the tunnel inboard migration suitable position, operation more than the repetition, until whole outside arc reinforcing bars target in place. In a second step, the longitudinal reinforcement is placed on the corresponding sliding bar 5.3 and is moved into position along the curved track by moving the sliding bar 5.3. Typically, the left longitudinal rebar transitions up from the left side of the curved track and the right longitudinal rebar transitions up from the right side of the curved track centered on the top longitudinal rebar. And then binding the longitudinal steel bars and the outer arc-shaped steel bars, and temporarily fixing the inner longitudinal steel bars at corresponding positions while binding the outer longitudinal steel bars. And thirdly, installing the inner arc-shaped reinforcing steel bars, and then binding the longitudinal and transverse reinforcing steel bars to finish construction.
In the description of the present invention, it should be noted that the terms "front", "back", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
