DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] The protective fence is often used for protection in the process of road and bridge construction or use. For example, during the process of road and bridge construction, the protective fence is needed to be placed around the foundation pit for protection when the foundation pit is excavated. After the bridge deck is erected, the protective fence is needed to be placed around the edge of the deck for protection when other bridge deck engineering is constructed. During the use process, i.e. after the road and bridge are built, the road and bridge surface is damaged when the vehicle starts to run normally, and the protective fence is needed to be placed around the repair site for protection of the safety of the repair workers. In these working conditions, the protective fence is used, but the installation mode of the protective fence is different due to different working conditions. For example, during the protection of the foundation pit, the support part of the protective fence is directly inserted into the soil, which is the most convenient way. During the construction above the wall beam, the connecting steel bars are usually reserved on the deck, and the support part of the protective fence is connected with the steel bars to fix the protective fence. During the normal operation of the road and bridge, the protective fence mainly plays a warning role when the workers need to maintain and repair the road. The support part of the protective fence is placed on the road surface. However, the main part of the protective fence (equivalent to the main frame of the application) is the core part of the protective fence for warning or blocking protection, and the main difference is the support part of the protective fence. The protective fence is usually an integral structure, so in the actual construction, the business of the related enterprises covers multiple scenes of road and wall beam construction and use. In order to adapt to different construction conditions, the related enterprises need to purchase different protective fences with different support parts according to different working conditions, which obviously increases the production cost of the enterprises. Therefore, the application provides the following scheme to solve the problem.

[0032] As shown in Figure 1 A protective device for road and bridge is disclosed, which comprises a main frame 1 and a plurality of different structures of mounting bases 5, and the plurality of different structures of mounting bases 5 correspond to different working conditions in the process of road and wall beam construction and use.

[0033] A plurality of metal fences 2 are uniformly welded in the main frame 1, and a fixing unit 3 is installed on both sides of the length direction of the main frame 1, and different main frames 1 can be connected together through the fixing unit 3.

[0034] Two main socket sleeves 4 are symmetrically welded on the lower side of the main frame 1, and the main socket sleeve 4 is detachably connected with any one of the mounting bases 5.

[0035] In the above embodiment, the main frame 1 of the present application is a rectangular frame structure welded by a plurality of steel pipes, and the plurality of metal railings 2 welded uniformly inside the main frame 1 can play a protective effect for workers together with the main frame 1 in actual use. In order to improve the warning effect of the entire device for workers or pedestrians, the main frame 1 and the metal railing 2 can be coated with a reflective warning material.

[0036] Two main socket sleeves 4 are symmetrically welded below the main frame 1 of the present application, wherein the main socket sleeve 4 can be freely replaced with the corresponding installation base 5 structure according to the actual use scene, and the selected installation base 5 is installed in the main socket sleeve 4 at the bottom of the main frame 1 of the present application. Thus, the main frame 1 with a plurality of metal railings 2 installed inside can be effectively applied in various working conditions. Compared with the integrated protective railing in the prior art, the present application not only effectively reduces the procurement cost of purchasing corresponding protective railings for different working conditions by enterprises, but also effectively improves the turnover utilization efficiency of the protective device of the present application, since most of the protective devices can be used in multiple working conditions.

[0037] Further, as shown in Figure 1 The first fixing hole 6 for installing the installation base 5 is provided on the main socket sleeve 4 along the radial direction thereof.

[0038] In the above embodiment, the first fixing hole 6 on the main socket sleeve 4 can be easily assembled and fixed with the installation base 5 by inserting connecting members such as bolts.

[0039] In one possible implementation, as shown in Figure 2 and Figure 3 The installation base 5 is a first installation base 51, which includes a support bottom plate 511, and a first stand 512 is welded on one end of the upper side of the support bottom plate 511. The outer diameter of the first stand 512 is equal to the inner diameter of the main socket sleeve 4, and the first stand 512 is provided with a second fixing hole 513, and the hole diameter of the second fixing hole 513 is equal to the hole diameter of the first fixing hole 6.

[0040] In the above embodiment, the hole diameter of the second fixing hole 513 on the first column 512 is equal to the hole diameter of the first fixing hole 6 on the main socket sleeve 4, so that when the worker uses the first mounting base 51, the second fixing hole 513 on the first column 512 and the first fixing hole 6 on the main socket sleeve 4 can be aligned to form a through hole therebetween, and at this time the worker can connect the first column 512 and the main socket sleeve 4 together by inserting a bolt into the through hole and cooperating with a nut. The support bottom plate 511 below the first column 512 is a flat plate, so that the main frame 1 internally provided with the metal railing 2 can be directly and stably placed on the ground through the support bottom plate 511. When maintenance and repair are required during the use of the road and bridge, the first mounting base 51 can be replaced below the main frame 1. When the worker works, the entire device provided with the first mounting base 51 is directly placed around the work area, and the main frame 1 can be automatically stabilized by the support bottom plate 511 in the structure, thereby quickly warning and guiding the passing vehicles around the work area.

[0041] Further, as shown in Figure 2 and Figure 3 , the upper side of the support bottom plate 511 away from the first column 512 is welded with a second column 7, and a support ring 8 is fixedly installed at the middle position of the second column 7. When the worker sets the hollow end shaft 10 of the warning banner 9 on the second column 7, the support ring 8 is used to provide support and limiting effect for the hollow end shaft 10.

[0042] In the above embodiment, during the normal use of the road and bridge, the worker can set the hollow end shaft 10 of the warning banner 9 at both ends on the two second columns 7 of the protective device facing the oncoming vehicles after unfolding the warning banner 9, and the support ring 8 on the second column 7 can support and limit the hollow end shaft 10 of the warning banner 9 to ensure that the unfolded warning banner 9 is hung at a suitable height of the corresponding protective device, thereby facilitating and quickly attracting the attention of the drivers of the oncoming vehicles.

[0043] In another possible implementation manner, as shown in Figures 4-6 , the mounting base 5 is a second mounting base 52, and the second mounting base 52 includes a third column 521. The outer diameter of the third column 521 is equal to the inner diameter of the main socket sleeve 4, the lower end of the third column 521 is a conical pointed structure, the third column 521 is provided with a third fixing hole 522 which has the same specification as the first fixing hole 6, and the third column 521 is fixedly connected with a positioning ring 523.

[0044] In the above embodiment, the lower end of the third column 521 is a conical tip structure, and the second mounting base 52 of this structure is suitable for being directly inserted into soft ground to fix the entire protective device. For example, at the initial stage of road and bridge construction, pit excavation is often carried out, and at this time, in order to prevent workers or mistaken pedestrians from falling into the pit, a protective device needs to be installed around the upper end of the pit. Since the surrounding of the pit is mostly soil structure and the ground is uneven, the second mounting base 52 is selected to be inserted into the soil to fix the entire device, which is not only convenient and fast to operate, but also has good fixing effect. The third column 521 in the second mounting base 52 is provided with a third fixing hole 522 which has the same specification as the first fixing hole 6, and its function is the same as the second fixing hole 513 in the previous embodiment, which facilitates workers to quickly assemble it with the main frame 1 through bolts and nuts. The positioning ring 523 on the third column 521 can play a positioning effect when workers insert it into the soil.

[0045] In yet another possible implementation, as shown in Figures 7-9 the mounting base 5 is a third mounting base 53, and the third mounting base 53 includes a fourth column 531, the outer diameter of the fourth column 531 is equal to the inner diameter of the main socket sleeve 4, and the fourth column 531 is provided with a fourth fixing hole 532 which has the same specification as the first fixing hole 6.

[0046] The lower end of the fourth column 531 is fixedly connected to the middle position of a horizontal mounting plate 533, the horizontal mounting plate 533 is provided with two steel bar mounting holes 534 which are penetrated, and the positions of the two steel bar mounting holes 534 on the horizontal mounting plate 533 are symmetrical about the fourth column 531. The lower side of the length direction of both ends of the horizontal mounting plate 533 is fixedly installed with an extension block 535, and the mutually close sides of the two extension blocks 535 are both arc-shaped structures. The two extension blocks 535 are movably installed with a U-shaped bolt 536.

[0047] In the above embodiments, when there are pre-reserved connecting steel bars at the edge of the work area during road and bridge construction, the third mounting base 53 of this structure can be used. For example, after the bridge beams are completed, some connecting steel bars are usually reserved at the edge of the beams to facilitate the subsequent installation of other components. Utilizing these connecting steel bars to install protective devices can not only reduce damage to the beam surface, but also ensure that the fixed and installed protective devices have sufficient capacity to guarantee the safety of workers when constructing other bridge deck works. In actual operation, workers can insert the reserved steel bars on the surface of the beam and slab upwards along the arc-shaped groove area on the extension block 535 into the corresponding steel bar installation holes 534 on the horizontal mounting plate 533. Then, by tightening the nuts on both ends of the U-bolt 536, the reserved steel bars, extension block 535, and horizontal mounting plate 533 are fixed together using the U-bolt 536. Next, the main socket sleeve 4 below the main frame 1 is fitted onto the fourth column 531. The fourth fixing through hole 532 on the fourth column 531 and the first fixing through hole 6 on the main socket sleeve 4 are fixedly connected together using bolts and nuts. This allows the main frame 1, which has metal railings 2 installed inside, to provide a stable and solid protective effect at the edge of the beam and slab.

[0048] Furthermore, such as Figure 1 and Figure 10 As shown, the fixing unit 3 includes two overlapping hooks 31. The overlapping hooks 31 in the fixing units 3 on both sides of the main frame 1 along the length direction are staggered, and each overlapping hook 31 is provided with a fifth fixing through hole 32.

[0049] In the above embodiments, the overlapping hooks 31 in the two fixed units 3 along the length of the main frame 1 are staggered. This ensures that when the two main frames 1 are connected together, the overlapping hooks 31 at their connection points are exactly offset, preventing them from interfering with each other during connection. The bent portion of the overlapping hook 31 has an arc-shaped structure. When it is necessary to connect the two main frames 1 together, the sides of the overlapping hooks 31 on the two main frames 1 that are exactly offset can be aligned first. After all the overlapping hooks 31 on the two main frames 1 are aligned, the axes of the arc-shaped bends in their overlapping hooks 31 are exactly collinear. At this time, the worker can insert a steel pipe 11 into these aligned overlapping hooks 31. A through hole of the same specification as the fifth fixed through hole 32 can be opened on the steel pipe 1 at the position corresponding to these overlapping hooks 31. In this way, the worker can use bolts and nuts to connect the two main frames 1 together through the steel pipe 11, so that they form an integral structure, so as to cover more construction areas that need protection in actual use.

[0050] Furthermore, the diameter of the fifth fixed through hole 32 is equal to the diameter of the first fixed through hole 6.

[0051] In the above embodiment, the hole diameter of the fifth fixed through hole 32 is also equal to that of the first fixed through hole 6, so that when different protective devices are connected together by using mounting bases 5 of different structures, the bolts and nuts used for connection can be universal, which is convenient for workers to work and for purchasing personnel to purchase.

[0052] The implementation principle of the embodiment is that the protective device has a detachable structure of the main frame 1 with the metal rail 2 inside and the mounting base 5 for placement or fixation, wherein the mounting base 5 has a plurality of different structures in actual use, so that workers can place the main frame 1 with the metal rail 2 inside by using the corresponding mounting base 5 structure when used in different use scenarios.

[0053] For example, when workers need to maintain and repair the local area of the road and bridge surface during the normal use of the road and bridge, the first mounting base 51 containing the first vertical column 512 can be selected, and in specific use, the second fixed through hole 513 on the first vertical column 512 and the first fixed through hole 6 on the main socket sleeve 4 are aligned to form a through hole therebetween, at this time, workers can connect the first vertical column 512 and the main socket sleeve 4 together by inserting a bolt into the through hole and cooperating with a nut. Since the support bottom plate 511 below the first vertical column 512 is a flat panel, workers can directly place the first mounting base 51 containing the first vertical column 512 around the work area when working, and the main frame 1 can be automatically stabilized by the support bottom plate 511 in the structure, so as to quickly warn and guide the passing vehicles around the work area. In order to further improve the warning effect, a warning banner 9 can be placed on the second vertical column 7 on the support bottom plate 511.

[0054] When workers need to place protective devices around the foundation pit during the initial construction of the road and bridge project, the second mounting base 52 containing the third vertical column 521 can be selected, and in specific operation, the third vertical column 521 with a conical tip structure at the lower end can be inserted into the soil on the side of the foundation pit, and then connected to the main socket sleeve 4 below the main frame 1 by bolts and nuts.

[0055] When the bridge engineering is completed, the reserved connecting steel bars on the side of the beam plate are convenient for the subsequent installation of other components, the workers can choose the third installation base 53 containing the fourth column 531, in actual operation, the workers can insert the reserved steel bars on the surface of the beam plate into the corresponding steel bar installation hole 534 on the horizontal installation plate 533 along the arc-shaped groove area on the extension block 535, and then fix the reserved steel bars, the extension block 534 and the horizontal installation plate 533 together by rotating the U-shaped bolts 536 and the corresponding nuts on both ends of the U-shaped bolts 536, then the main frame 1 is installed on the fourth column 531, and the fourth fixed hole 532 on the fourth column 531 and the first fixed hole 6 on the main socket sleeve 4 are fixed and connected together by bolts and nuts, so that the main frame 1 with the metal guardrail 2 installed inside can play a stable and firm protection effect on the side of the beam plate.

[0056] Compared with the integral protection guardrail in the prior art, the assembled protection device of the application not only effectively reduces the procurement cost of purchasing corresponding protection guardrails for different working conditions, but also effectively improves the turnover utilization efficiency of the protection device, because the main frame 1 containing the metal guardrail 2 in the protection device can be used in multiple working conditions.

[0057] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the application, and are not limited thereto; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
