[0016] A method for assembling and positioning a bridge guardrail reinforcement bar assembly device comprises the following steps:

[0017] S1. Calibration position: by installing pulleys at the four corners of the bottom end of the counterweight plate, the trailer mechanism drives the entire structure of the device to move, and through the rotation connection of the main shaft, multiple pendulum rods are rotated in azimuth, and then the horizontal detection function of the electronic level is used to monitor the horizontal condition of the trailer mechanism in real time, and the telescopic function of the electric push rod is used to make the four corners of the counterweight plate realize lifting and lowering adjustment, and then cooperate with the command conversion of the controller to facilitate the conversion of the data of the electronic level, thereby prompting each electric push rod to perform telescopic adjustment and prompting the counterweight plate to maintain levelness, and by pushing the trailer mechanism horizontally, the device is made to move parallel to the guardrail steel bar, and one of the pendulum rods is blocked by the guardrail steel bar, causing it to swing and rotate around the main shaft until one of the pendulum rods extends to the gap between the guardrail steel bars, and the remaining pendulum rods are respectively located outside the guardrail steel bars and fit with the outer wall of the guardrail steel bars, thereby quickly moving to the designated positioning area;

[0018] S2. Flush adjustment: The sliding sleeve is then moved to drive the support rod to rise and fall to the designated area, and the support rod is connected to the rotating shaft to facilitate the swing of the support rod around one side of the sliding sleeve.

The towing mechanism 500 includes a counterweight plate 5001 and a pulley 5002. The pulleys 500 are respectively installed at the four corners of the bottom end of the counterweight plate 5001. 2. A right-angled turning rod 600 is welded to one side of the top of the counterweight plate 5001. One end of the right-angled turning rod 600 is connected to one side of the outer wall of the standing beam 100. The rotating rod mechanism 400 includes a main shaft 4001 and a plurality of rocker rods 4002. Both ends of the main shaft 4001 are respectively provided with bearings. The main shaft 4001 is rotatably connected to the bottom end of the standing beam 100 and the top end of the counterweight plate 5001 through the bearings. The outer wall of the main shaft 4001 is connected to a plurality of rocker rods 4002, and the rocker rods 4002 are equidistantly distributed from each other.

[0032] The embodiment of the present invention is also implemented through the following technical solutions.

[0033] In accordance with an embodiment of the present invention, the standing beam 100 further includes a beam body 1001, a hollow groove 1002 and a spring 1003. The hollow groove 1002 is provided on one side of the outer wall of the beam body 1001. The inner top end of the hollow groove 1002 is connected to the spring 1003. Through the setting of the hollow groove 1002, space is provided for the height limiting rod 200 to move inside the standing beam 100.

One end of the spring 1003 is connected to the top side of the high cross bar 2001. The positional relationship between the slot 2003 and the hollow groove 1002 facilitates the improvement of the stability of the lifting and lowering activities of the high cross bar 2001, and the elastic effect of the spring 1003 on the high cross bar 2001 makes the high cross bar 2001 stable. 01 When in contact with the top of the guardrail steel bar, it remains in close contact. A slide groove is provided at the bottom end of the high cross bar 2001. The internal sliding connection of the slide block 2002 allows the slide block 2002 to slide inside the slide groove, so that the slide block 2002 can contact multiple positions of the top of the guardrail steel bar. Bolts 800 are threadedly connected on both sides of the outer wall of the high cross bar 2001. One end of the two bolts 800 is respectively fitted with both sides of the level ruler body 700. The knob 3002 is used for connection to facilitate tightening the sleeve 3001, so that the sleeve 3001 slides to either side of the standing beam 100 and maintains a tight connection.

[0035] According to an embodiment of the present invention, an electronic level 101 is embedded in the top center position of the trailer mechanism 500, and the pulley 5002 includes an electric push rod 500201 and a universal wheel 500202.

The electric push rod 500201 is electrically connected to the controller through a wire. The controller is electrically connected to the electronic level 101 and is controlled by the controller. Through the horizontal detection function of the electronic level 101, it monitors the horizontal condition of the trailer mechanism 500 in real time, and through the telescopic function of the electric push rod 500201, the four corners of the counterweight plate 5001 are adjusted to rise and fall, and then cooperated with the command conversion of the controller to facilitate the conversion of the data of the electronic level 101, thereby prompting each electric push rod 500201 to be telescopically adjusted and prompting the counterweight plate 5001 to remain horizontal.

[0036] According to an embodiment of the present invention, a movable positioning mechanism 300 is further provided on one side of the outer wall of the standing beam 100. The movable positioning mechanism 300 includes a sleeve 3001, a knob 3002, a support rod 3003, a rotating shaft 3004, a torsion spring 3005 and a blocking rod 3006. The sleeve 3001 is slidably connected to the outer wall of the standing beam 100. The rotating shaft 3004 is installed at one end of the sleeve 3001. The sleeve 3001 is rotatably connected to one end of the support rod 3003 through the rotating shaft 3004. The sleeve 3001 is rotatably connected to one end of the support rod 3003 through the rotating shaft 3004. The connection through the rotating shaft 3004 facilitates the support rod 3003 to swing around one side of the sleeve 3001.

[0037] In one embodiment of the present invention, a torsion spring 3005 is further provided on the outer wall of the rotating shaft 3004 , the top end of the supporting rod 3003 is connected to the blocking rod 3006 , and one end of the blocking rod 3006 is in contact with the outer wall of the standing beam 100 .

[0038] In an embodiment of the present invention, the outer wall of the sleeve 3001 is threadedly connected to the knob 3002, one end of the knob 3002 passes through the sleeve 3001 and fits against the outer wall of the standing beam 100. The elastic action of the torsion spring 3005 on the rotating shaft 3004 causes the support rod 3003 to be subjected to elastic torsion and maintain an elevation angle trend. Combined with the blocking action of the blocking rod 3006, the support rod 3003 maintains its elasticity and is in a horizontal state, which is conducive to the support rod 3003 being flush with the bottom of the guardrail steel bar.

[0039] In accordance with an embodiment of the present invention, damping shafts 102 are respectively installed on both sides of the top of the standing beam 100, and the standing beam 100 is hinged with brackets 103 through the two damping shafts 102.

[0040] In accordance with an embodiment of the present invention, further, a spacing is provided between one end of each of the plurality of pendulum rods 4002 and one side of the right-angled turning rod 600, and the spirit level body 700 is conveniently disassembled by being connected by bolts 800. A spacing is provided between one end of each of the plurality of pendulum rods 4002 and one side of the right-angled turning rod 600, and the setting of the spacing avoids collision between the pendulum rod 4002 and the right-angled turning rod 600. Example

[0041] Refer to the attached Figure 7 As shown, the present invention also provides a method for locating a bridge guardrail steel bar assembly device, comprising the following steps:

[0042] S1. Calibration position: By installing pulleys 5002 at the four corners of the bottom end of the counterweight plate 5001, the trailer mechanism 500 drives the entire structure of the device to move, and through the rotation connection of the main shaft 4001, the multiple rocker rods 4002 are rotated in azimuth. Then, through the level detection function of the electronic level 101, it monitors the level of the trailer mechanism 500 in real time, and through the telescopic function of the electric push rod 500201, the four corners of the counterweight plate 5001 are adjusted up and down, and then the command conversion of the controller is coordinated to facilitate the data of the electronic level 101 to be processed. The electric push rods 500201 are converted, thereby causing each electric push rod 500201 to be telescopically adjusted and causing the counterweight plate 5001 to remain horizontal. By pushing the towing mechanism 500 horizontally, the device is moved parallel to the guardrail steel bar. One of the swing rods 4002 is blocked by the guardrail steel bar, causing it to swing and rotate around the main axis 4001 until one of the swing rods 4002 extends to the gap between the guardrail steel bars, and the remaining swing rods 4002 are respectively located outside the guardrail steel bars and fit against the outer wall of the guardrail steel bars, thereby quickly moving to the designated positioning area.

[0043] S2. Flush adjustment: The sliding sleeve 3001 is then toggled to cause the sliding sleeve 3001 to drive the supporting rod 3003 to rise and fall to the designated area, and the supporting rod 3003 is facilitated to swing around one side of the sliding sleeve 3001 through the connection with the rotating shaft 3004. The torsion spring 3005 exerts an elastic force on the rotating shaft 3004, causing the supporting rod 3003 to be subjected to elastic torsion and maintain an elevation angle. The blocking effect of the blocking rod 3006 is combined with the support rod 3003 to maintain its elasticity and be in a horizontal state, thereby facilitating the supporting rod 3003 to be flush with the bottom of the guardrail reinforcement.

[0044] S3. Positioning completed: After steps S1 to S2, the level body 700 is kept in the specified positioning area, and the current value is compared with the specified positioning value to determine whether the bridge guardrail steel bar remains in the specified range, and adjustments are made until the positioning requirements are met;

[0045] S4. Transfer position: by pushing the device to move horizontally to a different position, and repeating the above step S3, the positioning data of the bridge guardrail steel bars at different positions are obtained, and the positioning work of the next position is performed according to the current value.
