Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The embodiment of the present application discloses a positioning device for positioning and adjusting the embedded part 2 of a bridge guardrail. Referring to Figure 1 , the positioning device for positioning and adjusting the embedded part 2 of a bridge guardrail includes an adjustable support and a positioning plate 1 for mounting the embedded part 2. The adjustable support can support the positioning plate 1 with the embedded part 2 on the bridge guardrail to be poured, so that the embedded part 2 extends into the templates on both sides of the bridge guardrail, so that when concrete is poured into the templates to form the bridge guardrail, the embedded part 2 can be embedded and fixed in the bridge guardrail. Considering the accuracy of the installation position of the embedded part 2, it is necessary to adjust the embedded part 2 to a suitable position in real time according to the construction situation. Therefore, the adjustable support includes a frame body and a plurality of lifting supports 3 for supporting the frame body on the bridge guardrail. The positioning plate 1 is movably installed on the frame body, and the positioning plate 1 can adjust its position among the plurality of lifting supports 3, thereby driving the embedded part 2 to quickly adjust its position, so that the embedded part 2 can be accurately positioned and installed.

[0027] To facilitate the quick adjustment of the erection position of the embedded part 2, referring to Figure 1, there are four lifting supports 3. The four lifting supports 3 are divided into two groups, with two in each group. The two lifting supports 3 in the same group are respectively fixed on the templates on both sides of the bridge guardrail. The two groups of lifting supports 3 are arranged at intervals along the length direction of the template. The frame body includes two first support rods respectively corresponding to the two groups of lifting supports 3 one by one, two sliders 5 slidably mounted on the two first support rods, a first locking member for locking the slider 5 on the first support rod, a second support rod for movably mounting the positioning plate 1 between the two sliders 5, and a second locking member provided on the second support rod; the length direction of the first support rod is consistent with the distribution direction of the templates on both sides of the bridge guardrail. The two ends of the first support rod are respectively connected to the two lifting supports 3 in the same group. The slider 5 can slide between the templates on both sides of the bridge guardrail along the length direction of the first support rod, and the first locking member can lock the slider 5 at any position on the first support rod. To facilitate quickly locking the slider 5, in the embodiment of the present application, the first support rod is set as the first screw rod 4, and the first locking member is set as two first nuts 6 threadedly sleeved on the first screw rod 4. The slider 5 is slidably sleeved on the first screw rod 4. The two first nuts 6 are respectively located on both sides of the slider 5. By driving the two first nuts 6 to rotate on the first screw rod 4, the two first nuts 6 respectively abut against both sides of the slider 5, so that the slider 5 can be locked at any position on the first screw rod 4.

[0028] Referring to Figure 1 and Figure 3 , the length direction of the second support rod is consistent with the length direction of the templates on both sides of the bridge guardrail. In the embodiment of the present application, the second support rod is two groups of second screw rods 7 provided on both sides of the positioning plate 1. Each group of second screw rods 7 has two. The two second screw rods 7 in the same group both pass through the slider 5 on the same side. The end of the second screw rod 7 away from the slider 5 is detachably connected to the side wall of the positioning plate 1, so that the positioning plate 1 is slidably mounted between the two sliders 5 under the support of the two groups of second screw rods 7, and the positioning plate 1 is not easy to rotate between the two sliders 5; by driving the second screw rod 7 to slide on the slider 5, the position of the embedded part 2 on the positioning plate 1 can be adjusted along the length direction of the bridge guardrail template. Correspondingly, the second locking member is a second nut 8 threadedly sleeved on the second screw rod 7. The second nut 8 is located on the side of the two sliders 5 facing away from each other. By rotating the second nut 8, the second nuts 8 on the two groups of second screw rods 7 respectively abut against the side walls on the side of the sliders 5 away from the positioning plate 1, so as to lock the two groups of second screw rods 7 between the two sliders 5, and further stably lock the positioning plate 1 and the embedded part 2.

[0029] In other embodiments, the second support rod is arranged as a screw rod passing through the entire positioning plate 1. Both ends of the screw rod are fixedly connected to two sliders 5 respectively. The positioning plate 1 can slide on the screw rod, thereby driving the embedded part 2 to adjust its position. Correspondingly, the second locking member is arranged as two nuts threadedly sleeved on the screw rod. The two nuts respectively abut against both sides of the positioning plate 1, thereby quickly locking the positioning plate 1 and the embedded part 2 between the two sliders 5.

[0030] In this application, the reason for choosing the former method for the setting of the second support rod is that after the casting of the bridge guardrail is completed, the positioning plate 1 and the embedded part 2 can be quickly removed from the second support rod, so that the adjustable support can be reused in a cyclic manner. To facilitate the quick removal of the positioning plate 1 from the second screw rod 7, referring to Figure 1 、 Figure 3 and Figure 4 , a U-shaped block 14 is arranged at one end of the second screw rod 7 away from the slider 5. The U-shaped block 14 is fixedly connected to the two second screw rods 7 in the same group, and one side of the positioning plate 1 is in snap-fit with the U-shaped block 14. A clamping screw 15 is passed through the U-shaped block 14, and a threaded hole threadedly adapted to the clamping screw 15 is provided on the positioning plate 1. The positioning plate 1 can be quickly locked in the U-shaped block 14 through the clamping screw 15. When it is necessary to remove the positioning plate 1 from the second screw rod 7, only need to remove the clamping screw 15 from the U-shaped block 14, and then pull the second screw rod 7 in the direction away from the positioning plate 1. At this time, the positioning plate 1 can be removed from the U-shaped block 14, so that the second screw rod 7 is separated from the positioning plate 1.

[0031] By moving the slider 5 along the length direction of the first screw rod 4 and driving the second screw rod 7 to slide on the slider 5, the embedded part 2 can be driven by the positioning plate 1 to adjust its position between the templates on both sides of the bridge guardrail, so that the embedded part 2 is accurately embedded to a suitable position. Although the position of the embedded part 2 can be quickly adjusted, the embedding depth of the embedded part 2 also needs to be considered. For this purpose, referring to Figure 1 and Figure 2, the lifting support 3 includes a base 31, a mounting frame 32 that is liftably arranged above the base 31, and a lifting adjustment member that is arranged between the mounting frame 32 and the base 31 and is used to adjust the distance between the two. The mounting frame 32 is arranged in a U shape, and through holes 9 for the first screw rod 4 to pass through are respectively formed through both side walls of the mounting frame 32. Through the through holes 9 on both side walls of the mounting frame 32, the first screw rod 4 can be stably supported. To facilitate the disassembly and storage of the mounting frame 32 and the first screw rod 4 when not in use, the first screw rod 4 is movably arranged through the through hole 9, so that the first screw rod 4 can be pulled out from the through hole 9 for removal. To facilitate the quick locking of the first screw rod 4 between the two mounting frames 32 during use, a third locking member for locking the first screw rod 4 between the two mounting frames 32 is arranged on the first screw rod 4. The third locking member is arranged as two third nuts 10 that are threadedly sleeved on the first screw rod 4. The two third nuts 10 are respectively located on the opposite sides of the two mounting frames 32, and by rotating the third nuts 10, the two third nuts 10 respectively abut against the side walls of the corresponding mounting frames 32, so that when the two mounting frames 32 are stably installed on the templates on both sides of the bridge guardrail by the base 31, the first screw rod 4 is also stably locked between the two mounting frames 32, and further the slider 5, the positioning plate 1 and the embedded part 2 that are locked on the first screw rod 4 by the second nut 8 are in a stable position.

[0032] Regarding the setting of the lifting adjustment member, the lifting adjustment member can be an electric push rod, a hydraulic cylinder, an adjustment screw rod 33, etc. Considering the manufacturing cost, in the embodiment of the present application, with reference to Figure 1 and Figure 2 , the lifting adjustment member is arranged as an adjustment screw rod 33 and two adjustment nuts 34 that are threadedly sleeved on the adjustment screw rod 33. One end of the adjustment screw rod 33 is vertically fixed on the base 31, and the other end vertically passes through the bottom wall of the mounting frame 32. The two adjustment nuts 34 respectively abut against the inner and outer sides of the bottom wall of the mounting frame 32, so that under the locking action of the two adjustment nuts 34, it can be stably locked above the base 31 at a certain height.

[0033] Considering that when adjusting the height between the mounting frame 32 and the base 31, the mounting frame 32 may rotate relative to the base 31, so that the two ends of the first screw rod 4 cannot be quickly aligned and installed in the through holes 9 of the two mounting frames 32. Therefore, with reference to Figure 2 , multiple groups of lifting adjustment members are arranged between the mounting frame 32 and the base 31. Considering the convenience of adjustment and the manufacturing cost, in the embodiment of the present application, two groups of lifting adjustment members are arranged. Under the adjustment action of the two groups of lifting adjustment members, the mounting frame 32 is not likely to rotate on the base 31.

[0034] Since the embedded part 2 needs to support the mechanical and electrical facilities, the embedded part 2 needs to ensure its verticality as much as possible during installation. With reference to Figure 1 andFigure 4 The positioning plate 1 is set as a rectangular plate. When installing and erecting the positioning plate 1, it is necessary to keep the positioning plate 1 in a horizontal state, and the embedded part 2 is arranged perpendicular to the positioning plate 1. To facilitate observing whether the positioning plate 1 is horizontal, a horizontal monitoring component for monitoring its horizontal state is provided on the positioning plate 1. The horizontal monitoring component includes a first bubble level 12 installed on the side wall of the positioning plate 1 and a second bubble level 13 installed on the top wall of the positioning plate 1. The length direction of the first bubble level 12 is the same as the length direction of the second screw rod 7, and the length direction of the second bubble level 13 is the same as the length direction of the first screw rod 4. When adjusting the positions of the positioning plate 1 and the embedded part 2, it is possible to quickly identify whether the current positioning plate 1 is horizontal and whether the embedded part 2 is vertical according to the first bubble level 12 and the second bubble level 13.

[0035] Refer to Figure 1 , Figure 2 and Figure 3 , since the first screw rod 4 is movably installed through the through hole 9 on the mounting bracket 32, the aperture of the through hole 9 is usually designed to be slightly larger than the rod diameter of the first screw rod 4. The second screw rod 7 is installed through the slider 5, so there may be manufacturing precision problems with the hole on the slider 5 for the second screw rod 7 to pass through, resulting in the second screw rod 7 being able to deflect on the slider 5. Therefore, when locking the two ends of the first screw rod 4 into the through holes 9 on the two mounting brackets 32 respectively and locking the second screw rod 7 on the slider 5, the situation where the first screw rod 4 and the through hole 9 are not coaxial and the second screw rod 7 is not perpendicular to the slider 5 may occur, and further the embedded part 2 installed on the positioning plate 1 is not in a vertical state. The mounting bracket 32 is installed on the base 31 in a lift-adjustable manner through a lift adjustment member, which can not only adjust the installation depth of the embedded part 2, but also finely adjust the verticality of the embedded part 2. When it is necessary to finely adjust the verticality of the embedded part 2, the first bubble level 12 and the second bubble level 13 can be referred to, and the heights of the four mounting brackets 32 can be finely adjusted, so as to be able to adjust the angles of the first screw rod 4 and the second screw rod 7 during locking installation to a certain extent, ensuring that the embedded part 2 can be erected vertically.

[0036] Although the installation depth of the embedded part 2 can be adjusted by adjusting the heights of the four mounting brackets 32, to further accurately adjust the installation depth of the embedded part 2, refer to Figure 4The positioning plate 1 is provided with a mounting hole for the embedded part 2 to pass through, and the embedded part 2 is movably provided with the mounting hole of the positioning plate 1, and the positioning plate 1 is provided with a fourth locking member for locking the embedded part 2, so that the installation depth of the embedded part 2 can be further adjusted according to the installation situation. In the embodiment of the present application, the top of the embedded part 2 is provided as a threaded rod, and the fourth locking member is provided as two fourth nuts 11 threadedly sleeved on the threaded rod of the embedded part 2, and the two fourth nuts 11 are respectively pressed against the upper and lower sides of the positioning plate 1, so that after the adjustment of the installation depth of the embedded part 2 is completed, the two fourth nuts 11 can stably lock the embedded part 2 on the positioning plate 1, ensuring that the embedded part 2 can maintain a stable installation position when casting the bridge guardrail.

[0037] The implementation principle of a positioning device for positioning and adjusting the embedded parts 2 of bridge guardrails in an embodiment of the present application is as follows: First, four bases 31 are fixed in groups of two on the templates on both sides of the bridge guardrail, and the mounting frames 32 on the four bases 31 are adjusted to the same height. Then, the two ends of the first screw rod 4 are respectively passed through the through holes 9 of the two mounting frames 32 of the same group, and the first screw rod 4 is locked between the two mounting frames 32 by the third nut 10. Then, the two groups of second screw rods 7 are respectively passed through the two sliders 5, and the two sliders 5 are moved along the length direction of the first screw rod 4 so that the second screw rods 7 on the two sliders 5 are aligned. Then, the two ends of the positioning plate 1 are fixedly connected to the second screw rods 7 on both sides by the clamping screws and the clamping blocks 14. Finally, the embedded part 2 is vertically mounted on the positioning plate 1 by the fourth nut 11, and the erection of the embedded part 2 can be completed at this time.

[0038] After the embedded part 2 is installed, the position of the embedded part 2 can be adjusted between the templates on both sides of the bridge guardrail by moving the slider 5 along the length direction of the first screw 4 and driving the second screw 7 to slide on the slider 5 according to the required embedded position of the embedded part 2, so that the embedded part 2 can be accurately installed to the appropriate position. Then the slider 5 is locked by the first nut 6 and the second screw 7 is locked by the second nut 8 to ensure the stability of the position of the embedded part 2. When adjusting the depth of the embedded part 2, the height between the mounting frame 32 and the base 31 or the installation depth of the embedded part 2 on the positioning plate 1 can be adjusted to ensure that the embedded part 2 is installed at a suitable height. At the same time, when adjusting the height between the mounting frame 32 and the base 31, it is necessary to refer to the first bubble level 12 and the second bubble level 13 to ensure the horizontality of the positioning plate 1 and the verticality of the embedded part 2.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
