[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] See also Figure 1-3 A road and bridge guardrail prefabrication auxiliary device in this embodiment includes a main vehicle 1 and a hoisting structure located on the main vehicle 1.

[0025] Specifically, the main vehicle 1 is driven by a flatbed trolley equipped with an electric motor, and can achieve translation on the road bridge.

[0026] The upper part of the main vehicle 1 is fixedly installed with a column 2 and a boom 3 that are vertically connected to each other. The lengths of the lever arms on both sides of the boom 3 that are relatively far away from the top of the column 2 are unequal. The boom 3 on the side with the long lever arm is used to provide an extended installation position. In addition, a reinforcing rod 4 is fixedly installed between the column 2 and the boom 3 to improve the supporting effect.

[0027] In this embodiment, a hook 5 is hung on one side of the short lever arm of the boom 3 , and a counterweight 6 is hung below the hook 5 .

[0028] With such a design, the main vehicle 1 will not tilt and fall toward the long lever arm end of the boom 3 due to the downward pressure of the counterweight 6 .

[0029] It should be noted that a hanging basket platform and a lifting fixture are provided on the long lever arm end of the boom 3, wherein the lifting fixture includes a slider 11 slidably mounted on the boom 3 and a movable structure connected to the slider 11. There are two sliders 11 in total at the front and rear of the boom 3, and a T-shaped steel 12 is fixedly installed between the two sliders 11 so that the two sliders 11 can move synchronously.

[0030] The movable structure in this embodiment includes a rotating rod 20 rotatably mounted at the lower end of the T-shaped steel 12, a gear 21 fixedly mounted at the lower end of the rotating rod 20, and a rack 24 fixed on the inner side of the boom 3. The rotation of the gear 21 can enable the T-shaped steel 12 to slide relative to the boom 3.

[0031] Preferably, in order to adjust the rotation of the gear 21, an adjusting motor 18 is fixedly installed on one end of the slider 11, and a main shaft 19 fixedly connected to the power end of the adjusting motor 18 is rotatably installed between the two sliders 11. A worm 22 is fixedly installed on the outside of the main shaft 19, and a worm wheel 23 is fixedly installed on the outside of the rotating rod 20, and the worm wheel 23 is meshed with the worm 22.

[0032] In a specific implementation, the adjusting motor 18 drives the main shaft 19 on the power end to rotate. The main shaft 19 rotates by driving the externally mounted worm 22 to rotate. The worm 22 rotates by meshing with the worm gear 23, so that the worm gear 23 is driven to rotate. At this time, the rotating rod 20 connected to the worm gear 23 rotates. After the gear 21 at the end of the rotating rod 20 rotates, it meshes with the rack 24, so that the slider 11 slides along the surface of the boom 3 and changes its position.

[0033] This design firstly enables the worm wheel 23 to cooperate with the worm 22 to drive the traction slider 11 to move, and secondly, through the meshing of the worm wheel 23 and the worm 22, the mediated transmission part can achieve self-locking.

[0034] In this embodiment, the lifting fixture also includes a lifting point 13 fixedly installed on the T-shaped steel 12 and a clamping plate located on the drooping end of the lifting point 13. The lifting point 13 can be used to conveniently assist in suspending the road and bridge guardrail below.

[0035] Preferably, the clamping plate includes a right-angle plate 15 fixed on the lifting end of the lifting point 13, and a slide plate 16 slidably connected to the right-angle plate 15. Specifically, by bringing the slide plate 16 close to the right-angle plate 15, the prefabricated formwork of the road and bridge guardrail can be clamped, making lifting convenient.

[0036] Furthermore, a bolt 17 threadedly connected to the right-angle plate 15 is threadedly installed on the slide plate 16 , and the clamping force of the slide plate 16 can be conveniently adjusted through the connection of the bolt 17 .

[0037] In this embodiment, the long arm end of the boom 3 is also hinged with a mounting pin 7, and a folding frame 8 is installed on the mounting pin 7, wherein the folding frame 8 is composed of two C-shaped steel welded beams, and the folding frame 8 is divided into two sections, and the end of one section of the folding frame 8 is fixedly connected to the outer wall of the mounting pin 7, so that the folding frame 8 can be rotated and folded relative to the boom 3.

[0038] It should be noted that a hanging basket 9 is rotatably mounted on the other end of the folding frame 8 away from the boom 3. The hanging basket 9 is used to provide standing space for the staff and can also place templates to improve the auxiliary convenience of the prefabrication of road and bridge guardrails.

[0039] In this embodiment, a suspension rope 10 for adjusting the height of the hanging basket 9 is also installed at the bottom of the suspension arm 3.

[0040] The working principle of the above embodiment is:

[0041] By placing the front template and the rear template of the road bridge guardrail to be prefabricated on the hanging basket 9, the main vehicle 1 is moved to the edge of the road bridge, so that the hanging basket 9 at the end of the boom 3 can be suspended to the outside of the road bridge. At this time, the template can be clamped between the right angle plate 15 and the slide plate 16 by adjusting the bolt 17, and the template on the hoisting hoist 14 can be assisted to be placed at the edge of the road bridge by the swaying hoisting hoist 14;

[0042] When it is necessary to adapt to the road and bridge adjustment, the adjusting motor 18 can be controlled to drive the main shaft 19 on the power end to rotate. The main shaft 19 rotates by driving the externally installed worm 22 to rotate. The worm 22 rotates by meshing with the worm wheel 23, so that the worm wheel 23 is driven to rotate. At this time, the rotating rod 20 connected to the worm wheel 23 rotates. After the gear 21 at the end of the rotating rod 20 rotates, it meshes with the rack 24, so that the slider 11 slides along the surface of the boom 3 and changes its position.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
