[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example: Please refer to Figure 1-2A bridge guardrail construction trolley includes a movable plate 1 and four movable wheels 2. The four movable wheels 2 are respectively installed at the four corners of the lower end of the movable plate 1. A support frame 3 is installed on the upper end of the movable plate 1. A fixed frame 4 is provided on the upper end of the support frame 3. A counterweight installation structure is installed on one side of the fixed frame 4, and a hoisting construction structure is installed on the upper end of the other side of the fixed frame 4.
[0020] The counterweight installation structure includes: four first mounting rings 5, eight lifting rods 6, eight second mounting rings 7, four connecting frames 8, two counterweight bodies 9, a fixing rod 10, two limiting rods 11, and two limiting frames 12;
[0021] Four first mounting rings 5 are respectively installed on both sides of the lower end of the fixed frame 4. The tops of eight lifting rods 6 are respectively connected to the four first mounting rings 5. The eight second mounting rings 7 are respectively connected to the bottom ends of the eight lifting rods 6. The four connecting frames 8 are respectively connected to the eight second mounting rings 7. The tops of two counterweight bodies 9 are respectively connected to the lower ends of the four connecting frames 8. The top of the fixed rod 10 is fixedly installed at the center of the lower wall of one end of the fixed frame 4. The two limiting rods 11 are respectively installed on both sides of the lower end of the fixed rod 10. The two limiting frames 12 are respectively movably fitted on the outside of the two counterweight bodies 9 and are respectively connected to the two limiting rods 11.
[0022] During the construction of bridge guardrails, workers first move the device to the designated position using the four wheels 2 at the lower end of the moving plate 1. The support frame 3 provides overall support for the fixed frame 4. Then, the eight second mounting rings 7 at the upper end of the four connecting frames 8 are connected to the eight lifting rods 6, and the tops of the eight lifting rods 6 are connected to the four first mounting rings 5 to lift the counterweight body 9. Next, two limiting frames 12 are fitted onto the upper ends of the two counterweight bodies 9. Then, the two limiting frames 12 are connected to the two limiting rods 11 with bolts. Under the connection between the fixed rod 10 and the fixed frame 4, the two counterweight bodies 9 are bound together. During the movement, the fixed rod 10 counteracts the inertia of the counterweight bodies 9, preventing the counterweight bodies 9 from shaking and affecting the construction. Finally, the construction basket is installed and lifted by the hoisting construction structure, thus achieving the purpose of constructing the bridge guardrail.
[0023] In the specific implementation process, the hoisting construction structure includes: traction rod 13 and two electric hoists 14;
[0024] The traction rod 13 is fixedly installed on the other side of the upper end of the fixed frame 4, and two electric hoists 14 are respectively installed on the upper end of the traction rod 13.
[0025] When constructing the bridge guardrail, the two electric hoists 14 at the upper end of the traction rod 13 are connected to the suspended platform. By having the two electric hoists 14 work synchronously, the height of the suspended platform can be adjusted, thereby realizing the hoisting of the suspended platform and the construction of the guardrail.
[0026] In the specific implementation process, a connecting component is installed between the fixed frame 4 and the support frame 3. The connecting component includes: a connecting frame 15 and four connecting rods 16.
[0027] The connecting frame 15 is fixedly installed at the upper center of the support frame 3. One end of each of the four connecting rods 16 is connected to both sides of the connecting frame 15, and the other end is connected to both sides of the fixing frame 4.
[0028] During installation, the two ends of the four connecting rods 16 are connected to the connecting frame 15 and the two sides of the fixing frame 4 respectively, which can ensure the stability of the fixing frame 4 under stress.
[0029] In the specific implementation process, the limiting frame 12 is connected to the limiting rod 11 by bolts.
[0030] In the specific implementation process, the shape of the limiting frame 12 is "U".
