Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] As Figures 1-4As shown, the embodiment provides a dust falling device for road and bridge construction, which comprises a support frame and a water spraying assembly selectively connected to the support frame. The support frame comprises a support bottom, a support middle and a support top. The support bottom comprises a plurality of first horizontal rods 1 and a plurality of supporting legs 2, wherein the supporting legs 2 are arranged in parallel to each other, and the first horizontal rods 1 are arranged above the supporting legs 2. Each first horizontal rod 1 is detachably connected to the upper side of the supporting leg 2. The support middle comprises four first vertical rods 3 and a plurality of second horizontal rods 4. The support top comprises two third horizontal rods 5, and the end of the third horizontal rod 5 is fixedly connected to the first vertical rod 3. The water spraying assembly is selectively connected to the first vertical rod 3 or the second horizontal rod 4.

[0047] In the embodiment, when the device is erected with a group of water spraying assemblies for dust falling, the plurality of first horizontal rods 1 and the plurality of supporting legs 2 are connected by bolts 6 to form the support bottom of the overall support frame. When the dust falling range is large, the two first horizontal rods in the middle of the entire row of first horizontal rods 1 are removed, and at the same time, the supporting leg in the middle of the entire row of supporting legs 2 is removed, and the side of the original support frame is connected to form the support bottom of the second support frame after extension. Then, the other two first horizontal rods 2 and the plurality of second horizontal rods 4 are used to connect the side of the support frame to form the support middle of the second support frame after extension. Finally, the two first horizontal rods are connected to the top to form the support top of the second support frame after extension.

[0048] Specifically, the first horizontal rod 1, the second horizontal rod 4, the third horizontal rod 5 and the first vertical rod 3 are respectively made of a square tube. In the first horizontal rod 1, a group of opposite side walls are provided with first horizontal holes 11, and another group of opposite side walls are provided with first vertical holes 12. In the second horizontal rod 4, a group of opposite side walls are provided with second horizontal holes 41, and another group of opposite side walls are provided with second vertical holes 42. In the third horizontal rod 5, a group of opposite side walls are provided with third horizontal holes 51, and another group of opposite side walls are provided with third vertical holes 52. In the first vertical rod 3, a group of opposite side walls are provided with first horizontal holes 31, and another group of opposite side walls are provided with first vertical holes 32.

[0049] As shown in the drawings, the water spraying assembly comprises a water tank 7, a water pump 8, a water pipe 9 and a plurality of water spraying nozzles 10. The water tank 7 is connected to the water pump 8, and the water pump 8 is connected to the water pipe 9. The water pipe 9 is connected to the water spraying nozzles 10. Figure 3As shown, the leg 2 is a tubular structure with a middle upward protruding section, wherein a set of opposite side walls of the protruding section are provided with fourth horizontal holes 21, and another set of opposite side walls are provided with fourth vertical holes 22; the fixed ends of the two ends of the leg 2 are respectively provided with fifth vertical holes 23 for fixing to the ground to ensure the stability of the entire device. Among them, the first vertical holes at the ends of the first horizontal rod 1 are detachably connected with the fourth vertical holes of the protruding section of the leg 2 by bolts 6. The first horizontal holes 31 of the first vertical rod 3 are detachably connected with the second horizontal holes 41 at the ends of the second horizontal rod 4 by bolts 6. The first longitudinal holes 32 of the first vertical rod 3 can also be used to connect the first horizontal rod 1, and also to form more groups of extended support frames. The second horizontal rod 4 can be detachably connected to the side of the first vertical rod 3, or can be connected below the plurality of first horizontal rods 1.

[0050] Further, the first horizontal rod 1, the second horizontal rod 4, the third horizontal rod 5, and the leg 2 are respectively provided with a plurality of roots. Two of the first horizontal rods 1 located in the middle of the row and two of the legs 2 located in the middle of the row are used as the support bottom of the extended support frame. The other two first horizontal rods 1 located in the middle are used as vertical supports of the extended support frame after being vertically arranged; two of the second horizontal rods 4 located in the middle and the other two first horizontal rods 1 located in the middle are used as the support top of the extended support frame.

[0051] In order to increase the stability of the support frame, diagonal bracing rods 7 are also arranged between the two first vertical rods 3. The arrangement of the diagonal bracing rods 7 can further enhance the overall stability of the support frame. During the construction of the road and bridge, especially when the water spraying assembly is working, the impact force of the water flow may have a certain influence on the support frame. The diagonal bracing rods can effectively disperse and offset these impact forces, ensure that the support frame remains stable during the dust falling operation, avoid shaking, deformation and other situations, and thus ensure the normal operation of the dust falling device and the construction safety.

[0052] In the embodiment, the water spraying assembly is selectively connected to the first horizontal hole 31 of the first vertical rod 3 or the second horizontal hole 41 of the second horizontal rod 4. The water spraying assembly includes a water spraying pipe 8 and a connecting disc 9 at both ends of the water spraying pipe 8, and a water inlet pipe 81 is connected to the water spraying pipe 8. The water inlet pipe 81 is connected to an external water pump. A plurality of spray heads 10 are arranged on the water spraying pipe 8, and each spray head is arranged in a row and has the same direction. The spray head 10 can be an atomizing spray head, which can spray water into fine mist to effectively reduce dust during construction. The connecting disc 9 is provided with an annular matrix of inner connecting holes 91 and outer connecting holes 92. Two adjacent inner connecting holes 91 and outer connecting holes 92 on the same diameter are used to fixedly connect the water spraying assembly. The distance between the two adjacent inner connecting holes 91 and outer connecting holes 92 on the same diameter is the same as the distance between the two adjacent first horizontal holes 31, and the distance between the two adjacent second horizontal holes 41. A sleeve 93 is arranged on the inner side of the connecting disc 9. The water spraying pipe 8, the connecting disc 9 and the sleeve 93 are made of stainless steel, and the end of the water spraying pipe 8 is embedded in the sleeve 93 and fixed by welding.

[0053] The bolt is used to fixedly connect the two adjacent inner connecting holes 91 and outer connecting holes 92 on the same diameter at different positions, so that the spray heads on the water spraying assembly can form different directions, that is, the design of the plurality of inner connecting holes 91 and outer connecting holes 92 on the connecting disc 9 can form different water spraying directions to adapt to the dust reduction needs of different construction positions. The water spraying assembly can be fixed at different heights of the first vertical rod 3 to form water spraying assemblies at different heights. The water spraying assembly can also be fixed to the second horizontal rod at different heights to form water spraying assemblies at different heights. The water spraying assembly is installed in a position suitable for different road and bridge construction conditions.

[0054] The water spraying assembly can be selectively connected to the first vertical rod 3. By aligning the adjacent inner connecting holes 91 and outer connecting holes 92 on the connecting disc 9 on the same diameter with the first horizontal hole 31 (or the first longitudinal hole) of the first vertical rod 3, and then using a bolt 6 or the like fastener to fixedly connect, the water spraying assembly is installed on the first vertical rod 3. In this way, the water spraying assembly can be installed at a suitable height of the first vertical rod 3 according to the height requirement of the construction, and the upper space of the construction area can be dusted.

[0055] The water spray assembly can also be optionally connected to the second horizontal bar 4. Align the adjacent inner connecting holes 91 and outer connecting holes 92 of the same diameter on the connecting plate 9 with the second horizontal hole 41 (or second vertical hole) on the second horizontal bar 4, and secure them using fasteners such as bolts 6. The water spray assembly installed on the second horizontal bar 4 can suppress dust in the central space of the construction area, and works in conjunction with the water spray assembly installed on the first vertical bar to form a more comprehensive dust suppression coverage.

[0056] The dust suppression equipment for road and bridge construction provided in this embodiment places the first horizontal bar 1 above the support leg 2. Fasteners such as bolts 6 pass through the first horizontal hole 11 of the first horizontal bar 1 and the fourth vertical hole 22 of the support leg 2, achieving a detachable connection between the first horizontal bar 1 and the support leg 2, thereby establishing the basic structure of the support base. Two of the first horizontal bars 1 and two of the support legs 2 located in the middle can be used as the support base for an extended support frame. Figure 4 As shown, when it is necessary to expand the coverage area of ​​the dust suppression equipment, the two first horizontal bars 1 and the two support legs 2 can be connected to the original support bottom in the above connection method to form a larger support bottom structure, providing a foundation for the subsequent extension of the support middle and support top. Then, using two more first horizontal bars 2, the two vertical first horizontal bars 2 and several second horizontal bars 4, one side of the original support frame is connected to form the support middle of the extended second support frame; it is worth noting that the vertical first horizontal bars 2 and the first vertical bars 3 are reinforced by another horizontally arranged first horizontal bar. Finally, two more first horizontal bars are connected to the top to form the support top of the extended second support frame. In this embodiment, the first crossbar 1, the second crossbar 4, the third crossbar 5, and the support leg 2 are respectively equipped with various horizontal and vertical connecting holes. This design can ensure the stability when assembled into a support frame. The multiple and detachable design also facilitates the formation of an extended support frame. This allows for the installation of corresponding water spray components according to the needs of road and bridge construction, meeting the requirements of different dust suppression ranges under different construction conditions.

[0057] The connecting plate 9 is equipped with an inner connecting hole 91 and an outer connecting hole 92 arranged in a ring matrix. Two adjacent inner connecting holes 91 and outer connecting holes 92 located on the same diameter are used to fix the water spray assembly. This design allows the water spray assembly to be installed in different positions as needed, and different water spray directions can be formed by selecting two adjacent inner connecting holes 91 and outer connecting holes 92 at different positions to fix it, so as to adapt to the dust suppression requirements of different construction positions.

[0058] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
