Description

Technical Field

[0001] This invention relates to the field of bridge railing reinforcement positioning, and particularly to a bridge railing reinforcement positioning device. Background Technology

[0002] In highway bridge construction, crash barriers are not only a guarantee of driving safety, but also a reflection of the bridge's appearance. Their engineering quality is of paramount importance for safety assurance. Bridge guardrails are generally constructed by installing steel bars and then pouring concrete. The quality of the steel bar installation is crucial and will affect the service life of the guardrails.

[0003] Referring to the existing Chinese patent with publication number CN218175607U, it discloses a bridge railing rebar positioning device, including a base, a vertical rod and a horizontal rod. The horizontal rod is fixed to the top of the vertical rod and is perpendicular to the vertical rod. The lower end of the vertical rod is set on the base. Two markers are provided at the head end of the horizontal rod (used to locate the installation position of the railing rebar and the template installation position, respectively). The distance between the two markers is adjustable. The lower part of the vertical rod or the base is provided with a positioning mechanism for aligning with the construction ink line.

[0004] The aforementioned bridge railing rebar positioning device, by accurately positioning the top of the railing rebar, reduces repetitive measurements by workers, alleviates their labor intensity, solves the problems of inaccurate rebar positioning and low installation efficiency, improves the construction speed of crash barriers, significantly shortens the construction cycle of crash barrier rebar installation, and reduces manpower input. However, this bridge railing rebar positioning device still has some drawbacks, such as: 1. Because the laser instrument needs to be placed on a horizontal surface, the requirements for the bottom surface are high, and the levelness of the bridge surface needs to be determined. If the levelness is not adjusted, the positioning accuracy will be reduced; 2. After the laser instrument is moved and positioned, it is easy to misalign or shift. Even a small amount of shift will reduce the positioning error, and long-term use will increase the resulting error; 3. The measuring part is relatively long and occupies a lot of space when stored, making it inconvenient to store. Summary of the Invention

[0005] In view of the problems mentioned in the background art, the purpose of the present invention is to provide a bridge railing reinforcement positioning device to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A bridge railing reinforcement positioning device includes a fixed base, an adjusting plate above the fixed base, two sets of side plates welded to one end of the lower surface of the adjusting plate, a support plate welded to one end of the upper surface of the fixed base, the top of the support plate hinged between the two sets of side plates, a fixed plate welded to the other end of the upper surface of the fixed base, an adjusting screw threadedly connected to the fixed plate, a moving block rotatably connected to one end of the adjusting screw, a sliding lower surface of the other end of the adjusting plate slidably disposed on the upper surface of the moving block, a handwheel welded to the other end of the adjusting screw, a level bubble meter fixedly disposed on the outer surface of the adjusting plate, a first spring seat fixedly disposed on the upper surface of the fixed base, a second spring seat fixedly disposed on the lower surface of the adjusting plate, and a first return spring fixedly disposed between the first spring seat and the second spring seat.

[0008] A column is welded to the upper surface of the adjusting plate. Several sets of positioning holes are opened on the column. A sliding sleeve is slidably fitted on the circumference of the column. A fastening bolt is threaded onto the sliding sleeve. The sliding sleeve is fixedly connected to one set of positioning holes through the fastening bolt. A crossbar is connected to one side of the sliding sleeve through a fixing component. A standard rod is welded to the other end of the crossbar. A reference spotlight is fixedly installed at the connection between the crossbar and the standard rod. A movable frame is slidably connected to the standard rod. A laser is fixedly installed on the outer surface of the movable frame. A tightening bolt is threaded onto the upper surface of the movable frame. The other end of the tightening bolt contacts the surface of the standard rod.

[0009] By adopting the above technical solution, a horizontal bubble meter is set up. Rotating the handwheel drives the adjusting screw to move, which in turn moves the moving block. The restoring force of the first return spring allows one end of the adjusting plate to move stably along the surface of the moving block, facilitating the adjustment of the plate's angle and thus enabling leveling. By setting a tightening bolt, after the moving frame moves on the standard rod and the laser meter's accurate position is determined, the bolt is tightened to stably fix the moving frame on the standard rod, preventing deviation and improving the accuracy of rebar positioning. The fixing assembly allows for easy disassembly and assembly of the crossbar, facilitating both use and storage. Furthermore, several sets of positioning holes allow the fastening bolts to position the sliding sleeve at different heights, facilitating measurement and positioning at various heights.

[0010] Preferably, self-locking casters are fixedly installed on all four sides of the lower surface of the fixed base.

[0011] By adopting the above technical solution, it is convenient to move the fixed base.

[0012] Preferably, a stabilizing component is fixedly disposed on the outer surface of the fixed base, and four sets of the stabilizing components are disposed on both sides of the fixed base.

[0013] By adopting the above technical solution, the stability of the fixed base is increased when it is not moved.

[0014] Preferably, the stabilizing component includes a positioning plate, a rotating screw, a knob, and a pressure plate. The positioning plate is welded to the outer surface of the fixed base, the rotating screw is threaded onto the positioning plate, the knob is welded to the top of the rotating screw, and the pressure plate is welded to the bottom of the rotating screw.

[0015] By adopting the above technical solution, rotating the knob drives the rotating screw to rotate, and the rotating screw drives the pressure plate to move downward, so that the pressure plate comes into contact with the bridge surface, thereby increasing the friction and reducing the risk of movement.

[0016] Preferably, the movable block is configured as a trapezoidal structure, and a guide rod is welded to the bottom of the movable block. The guide rod passes through the fixed plate and is slidably connected to the fixed plate.

[0017] By adopting the above technical solution, it is convenient to level the adjusting plate and prevent the moving block from rotating.

[0018] Preferably, a limiting block is welded to the upper surface of the fixed base, and the height of the top of the limiting block is higher than the height of the smaller end of the movable block.

[0019] By adopting the above technical solution, one end of the adjusting plate is prevented from moving to a height lower than one end of the moving block, thereby avoiding the possibility that the moving block cannot be inserted into the bottom of the adjusting plate.

[0020] Preferably, a triangular reinforcing plate is welded between the bottom outer surface of the column and the upper surface of the adjusting plate.

[0021] By adopting the above technical solutions, the stability of the columns is increased, and the structural strength is enhanced.

[0022] Preferably, the fixing component includes a fixing seat, a pin, a socket, a limiting pin, a slot, and a pull ring. The fixing seat is welded to one side of the sliding sleeve, the pin is welded to the lower surface of one end of the crossbar, the socket is opened inside the fixing seat, the pin is inserted into the socket, the limiting pin is slidably disposed in the fixing seat, the slot is opened on the outer surface of the pin, one end of the limiting pin is inserted into the slot, and the pull ring is welded to the end of the limiting pin.

[0023] By adopting the above technical solution, by pulling the pull ring, the pull ring moves the limiting pin out of the slot, thereby allowing the insertion post to be moved out of the insertion hole, thus enabling the crossbar to be disassembled and stored.

[0024] Preferably, the fixing assembly further includes a second return spring and a cavity, the cavity being formed inside the fixing seat, the second return spring being disposed inside the cavity, the second return spring being sleeved on the circumference of the limiting pin, and the end of the second return spring away from the pull ring being fixedly connected to the surface of the limiting pin.

[0025] By adopting the above technical solution, the limiting pin can be easily and stably inserted into the slot, thereby improving the stability of the installation.

[0026] Preferably, the outer surface of the standard rod is provided with scale lines.

[0027] By adopting the above technical solution, it is convenient to measure distances and to accurately locate objects.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] First, the present invention uses a horizontal bubble meter, which drives the adjusting screw to move by rotating the handwheel. The adjusting screw drives the moving block to move, and the restoring force of the first reset spring makes one end of the adjusting plate move stably along the surface of the moving block, thereby facilitating the change of the angle of the adjusting plate and making it easier to level the adjusting plate.

[0030] Secondly, by setting a tightening bolt, after the moving frame moves on the standard rod and the accurate position of the laser instrument is determined, the moving frame is stably fixed on the standard rod by tightening the bolt, thereby preventing the moving frame from shifting and improving the accuracy of rebar positioning.

[0031] Third, by setting a fixing component, the present invention can easily disassemble and assemble the crossbar, thus facilitating assembly during use and storage when not in use. In addition, by setting several sets of positioning holes, the fastening bolts can position the sliding sleeve at different heights, thus facilitating measurement and positioning at different heights.
