When installing the air-facing formwork of the anti-collision concrete guardrail, the traditional operation method is to directly use cranes and other equipment in conjunction with manual assembly and fixation of the formwork. Due to the small operating space, difficulty in installation and fixation, and high risk, the formwork is prone to accidentally falling, especially when crossing existing roads for construction, the risk is even greater.

[0003] In view of the above problems, the prior art (publication number CN215561917U) discloses a crash barrier formwork construction trolley, including a trolley body, the lower surface of the trolley body is fixedly connected to a hydraulic cylinder, the telescopic end of the hydraulic cylinder is fixedly connected to a working box, the sides of the working box are respectively provided with an entrance and a working port, the inner bottom wall of the working box is fixedly connected to a handrail, the surface of the handrail is slidably connected to a sliding ring, the surface of the sliding ring is respectively fixedly connected to a first strap and a second strap, and the end of the first strap away from the sliding ring is fixedly connected to a Japanese-shaped buckle. The crash barrier formwork construction trolley, by providing a working box and a working port, is convenient for workers to install the outer template, and by providing a handrail, a sliding ring, a first strap, a second strap and a Japanese-shaped buckle, it is convenient for workers to connect to the working box and protect the workers, thereby achieving the effect of protecting the workers and protecting the personal safety of the workers.

[0004] However, during use, the above-mentioned anti-collision barrier formwork construction trolley only offsets the gravity of the working box by setting a counterweight, so that there is still a risk of rollover when installing the free surface formwork. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a crash barrier template construction trolley, which can solve the problem that there is still a risk of rollover when installing the free surface template.

[0006] In order to solve the above technical problems, according to one aspect of the utility model, more specifically a crash barrier formwork construction trolley includes a base plate, a first universal wheel is fixed at the bottom corner of the base plate, a counterweight device is provided above the base plate, support rods are fixed at the top corners of the base plate, cross bars are fixed to the tops of the two front support rods and the two rear support rods, a lifting hydraulic cylinder is fixed to the middle right part of the bottom of the cross bar, an operating box is fixed to the bottom of the two lifting hydraulic cylinders, and a safety device is provided at the bottom of the operating box.

[0007] Furthermore, the counterweight device includes two adjusting tubes, which are fixed at the front and rear of the top of the base plate, and an adjusting rod is passed through the inside of the adjusting tube. A limiting block is fixed to the right end of the adjusting rod, a second universal wheel is fixed to the left side of the bottom of the adjusting rod, a mounting plate is fixed to the left side of the top of the two adjusting rods, and a counterweight block is fixed in the middle of the top of the mounting plate.

[0008] Furthermore, the safety device includes two guide rails, which are fixed to the front and rear sides of the bottom of the operation box, a sliding rod is provided in the middle of the two guide rails, and sliders are fixed to the front and rear ends of the sliding rods, and the sliders are inserted into the inside of the guide rails, and mounting rods are symmetrically fixed to the front and rear sides of the bottom of the sliding rods, an electric telescopic rod is fixed to the left side of the top of the mounting rod, a pad is fixed to the top of the electric telescopic rod, a threaded groove is provided in the middle of the right side of the sliding rod, a motor is fixed to the right side of the bottom middle of the operation box, a threaded rod is fixed to the left end of the output shaft of the motor, and an anti-slip block is fixed to the left end of the threaded rod.

[0009] Furthermore, the bottom of the first universal wheel and the bottom of the second universal wheel are in the same horizontal plane.

[0010] Furthermore, the outer wall of the sliding block fits with the inner part of the guide rail.

[0011] Furthermore, the internal thread of the thread groove matches the thread of the threaded rod.

[0012] The utility model provides a kind of anti-collision barrier template construction trolley with beneficial effects as follows: the trolley can be moved by the first universal wheel and the second universal wheel. When installing the template, the mounting plate can be moved to the left by the adjusting tube and the adjusting rod in cooperation with the second universal wheel, thereby the counterweight block is moved to the left to increase the offset effect on the gravity of the operation box, further increasing the stability of the trolley when installing the template. After use, the mounting plate is moved to the right to drive the counterweight block to move to the right, thereby reducing the volume of the trolley and facilitating the movement of the trolley. The lifting hydraulic cylinder can adjust the height of the operation box, which is convenient for adjusting the height of the operation box according to the needs of use. When installing the template, the rotation of the motor drives the threaded rod to rotate, and the installation rod is driven to move to the left under the action of the guide rail, the sliding block and the sliding rod, and finally drives the electric telescopic rod and the cushion block to move to the left to the bottom of the bridge deck. At this time, the electric telescopic rod is extended to make the cushion block press against the bottom of the bridge deck and cooperate with the first universal wheel and the second universal wheel of the trolley to further increase the stability of the trolley. After use, the electric telescopic rod is shortened first and then the motor is reversed to retract the electric telescopic press and the cushion block to the bottom of the operation box.
