Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a dust suppression device. Background Technology

[0002] Construction work in urban areas generates a large amount of dust, which seriously affects the surrounding air quality and residents' lives. Currently, the common method for dust suppression is to install a spray dust suppression system on top of the construction site enclosure. This system typically includes a transmission pipe running along the enclosure and multiple atomizing nozzles installed at intervals on the transmission pipe.

[0003] In existing technologies, the transmission pipe is typically directly bound and fixed to a square steel pipe (hereinafter referred to as "square steel") at the top of the enclosure using plastic cable ties, wire, or simple clamps. This fixing method has significant drawbacks: First, the binding force is difficult to control precisely. If the binding is too tight, the transmission pipe (especially the plastic hose) will be deformed under pressure, affecting the smooth flow of water inside and even causing uneven water output from the nozzles; if the binding is too loose, it cannot remain stable under wind load, water flow impact, or human touch, easily causing the transmission pipe and nozzles to shift or tilt, affecting the dust suppression range and effect. Second, during the non-working periods of the intermittent operation of the spray system, the transmission pipe may shrink due to temperature changes or material loosening, further exacerbating the problem of loose fixing, creating safety hazards and adjustment burdens for the next start-up. In addition, the surface temperature of the metal square steel is extremely high under summer sunlight, and direct contact may cause the plastic transmission pipe to age or deform more quickly.

[0004] Therefore, there is an urgent need for an installation and fixing device that can quickly and stably fix the dust suppression system transmission pipe, adapt to harsh on-site working conditions, and is easy to disassemble and install. Summary of the Invention

[0018] When the insert rod moves upward, the two clamping plates are driven to move away from each other through the linkage transmission assembly;

[0019] When the insert rod moves downward, the two clamping plates are driven to move closer to each other through the linkage transmission assembly to clamp the square steel.

[0020] In one embodiment, the linkage transmission assembly includes: a shaft plate, two limiting plates, two adjusting rods, and a fixed shaft;

[0021] The shaft plate is disposed at the top of the insertion rod;

[0022] The limiting plate is disposed on the inner side of the top of the vertical section of each of the card plates;

[0023] The two adjusting rods are located on both sides of the insert rod, and the first end of each adjusting rod is hinged to the corresponding limiting plate, and the second end is hinged to the side of the shaft plate.

[0028] The elastic reset member is disposed between the top of the lifting groove and the lifting plate, providing a downward elastic force to the lifting plate;

[0029] The locking rod is vertically installed at the bottom of the lifting plate;

[0030] Multiple locking holes are spaced apart vertically at the top of the vertical section of each card plate, and the locking rod passes through the locking holes;

[0031] The operating button is located on the outer wall of the fixed block and connected to the lifting plate, and is used to drive the lifting plate to move upward so that the locking rod disengages from the lock hole.

[0033] In one embodiment, a magnetic block is provided on the upper side wall of the insertion rod, and an adsorption part corresponding to the magnetic block is provided inside the fixing block.

[0042] Based on the above description and practical experience, the dust suppression device of this invention has the following advantages compared with traditional dust suppression devices:

[0043] 1. When using this invention, by pushing the operating button upwards, the locking rod can be moved out of the lock hole. At this time, the two sets of clamping plates are adjusted to separate them. At the same time, after inserting the rod into the slot on the square steel, the two sets of clamping plates are adjusted again to bring them closer together and close. By pushing the operating button downwards, the locking rod is moved into the lock hole, which can limit the lateral movement of the clamping plates, thereby preventing the clamping plates from moving downwards. This allows the transmission pipe to be quickly and easily and stably fixed on the square steel, preventing the transmission pipe and atomizing nozzle from becoming loose or shifting due to poor fixing during operation and non-operation periods.

[0044] 2. When using this invention, the transmission pipe is supported and fixed to the square steel by the fixing block, which can effectively avoid direct contact between the transmission pipe and the square steel. This reduces the direct conduction of high temperature from the square steel to the transmission pipe and the water flow inside the transmission pipe in hot weather, thus reducing the impact of high temperature on the transmission pipe and the spraying operation.

[0054] like Figures 1 to 4 As shown in the figure, this embodiment discloses a dust suppression device that solves the problems of unstable fixing, easy loosening, easy deformation, great temperature influence, and inconvenience in disassembly and assembly when the transmission pipe of the dust suppression device is fixed to the square steel of the enclosure by means of cable ties or other methods.

[0055] like Figure 1 and Figure 2As shown, the present invention mainly includes: a transmission pipe 1, several atomizing nozzles 2, and multiple fixing components. The transmission pipe 1 is typically a flexible plastic or rubber pipe used to transport dust suppression water from a water source. The atomizing nozzles 2 are conventional spray elements, which are fixedly installed on the transmission pipe 1 at certain intervals along its length, according to the required dust suppression range and density. Each atomizing nozzle 2 communicates with the inner cavity of the transmission pipe 1, allowing the water flow to be atomized and sprayed out. The fixing components are also arranged at intervals along the length of the transmission pipe 1, and each fixing component is located between two adjacent atomizing nozzles 2, ensuring that the transmission pipe 1 is effectively supported and fixed near the working position of the atomizing nozzle 2, avoiding nozzle directional deviation caused by partial suspension or shaking of the pipe. Each fixing component mainly includes three parts: a fixing block 3, a clamping mechanism, and a locking mechanism. The top of the fixing block 3 is designed with an arc-shaped support or clamp structure that matches the shape of the transmission pipe 1, used to stably support and restrict the transmission pipe 1, allowing it to be placed smoothly above the enclosure. The clamping mechanism is connected to the bottom of the fixing block 3. Its main function is to directly connect to the metal square steel at the top of the construction site enclosure, using a mechanical structure to grip and fix the square steel. A locking mechanism is installed on the fixing block 3 and connected to the clamping mechanism. After the clamping mechanism completes its clamping action, the locking mechanism activates, locking the clamping mechanism to prevent accidental loosening under vibration, wind force, or the pipe's own stress, thus ensuring the entire fixing assembly remains reliably clamped for a long period. Through this fixing assembly, the device can be quickly deployed and disassembled, while providing significantly superior fixing strength and stability compared to traditional binding methods.

[0056] The clamping mechanism consists of a rod 8, two symmetrically arranged clamping plates 7, and a linkage transmission assembly. A vertical, through-hole or non-through-hole mounting channel is machined at the bottom center of the fixing block 3. The rod 8 is installed in the mounting channel in a sliding manner. The lower end of the rod 8 is designed to be tapered or flat-headed for easy insertion. Before actual installation, mounting holes matching the lower end size of the rod 8 need to be pre-drilled on the top surface of the square steel of the enclosure. The primary function of the rod 8 is positioning; by inserting it into the mounting hole, the accurate position of the fixing assembly along the length of the square steel can be quickly determined. On the left and right side walls of the fixing block 3, a vertical, long clamping groove 6 is provided. Both clamping plates 7 are L-shaped metal or high-strength plastic parts. The upper part of their vertical sections passes through the corresponding clamping groove 6 and can slide within a certain range within the groove 6. Their horizontal sections extend outwards and downwards from the bottom of the fixing block 3. The linkage drive assembly is housed within an adjustment groove 24 inside the fixed block 3. Auxiliary grooves 22 may also be formed on both sides or at the ends of the adjustment groove 24 to provide additional clearance space for the swinging of the adjustment rod 18 or the movement of the limiting plate 17, ensuring smooth and interference-free transmission. The linkage drive assembly converts the movement of the top of the insertion rod 8 into the opening and closing movement of the horizontal sections of the two clamping plates 7. Its working principle is as follows: When the device needs to be installed, the operator lifts the insertion rod 8 upwards. The insertion rod 8 moves upwards, and through the transmission and conversion of the linkage drive assembly, drives the vertical sections of the two clamping plates 7 to slide away from each other (i.e., outwards) within the clamping groove 6. Since the clamping plates 7 are L-shaped, the outward movement of their vertical sections causes the lower horizontal sections to swing outwards synchronously, thus widening the opening between the two horizontal sections, facilitating their placement across the top of the square steel. When the insertion rod 8 is pressed downwards, its movement is transmitted in the opposite direction through the linkage drive assembly, driving the vertical sections of the two clamping plates 7 to slide closer to each other (i.e., inwards), thereby causing their horizontal sections to close inwards. Ultimately, the inner sides of the two horizontal sections will firmly support the lower edges (or bottom surface) of the square steel from below, forming a solid mechanical clamp. The vertical movement of the insert rod 8 drives the clamping plate 7 to clamp horizontally. The structure is compact, the force transmission is direct, and the operation is intuitive.

[0057] The linkage assembly includes a shaft plate 16, two limiting plates 17, two adjusting rods 18, and a fixed shaft 20. The shaft plate 16 is a plate-shaped part fixed to the top of the insert rod 8, and moves up and down with the insert rod 8. A limiting plate 17 is fixedly installed on the inner side of the top of the vertical section of each clamping plate 7, primarily providing a hinge point. The two adjusting rods 18 are roughly elongated, arranged on the left and right sides of the insert rod 8. One end of each adjusting rod 18 is connected to the corresponding limiting plate 17 via a pivot or hinge pin, allowing relative rotation; its other end is also hinged to the side of the shaft plate 16. Thus, the shaft plate 16, adjusting rods 18, and limiting plates 17 form a variable triangular linkage mechanism with three hinge points as vertices. The fixed shaft 20 is a shaft horizontally fixed in the adjusting groove 24 inside the fixed block 3, located approximately in the middle of the adjusting rod 18. Each adjusting rod 18 has a long, movable groove 19 along its length. The adjusting rod 18 is not directly hinged to the fixed shaft 20, but rather sleeved onto the fixed shaft 20 through this movable groove 19. The fixed shaft 20 passes through the movable groove 19 and can slide relative to it along the length of the groove. When the insert rod 8 drives the shaft plate 16 to move up and down, it forces the two adjusting rods 18 to swing around their hinge point with the limiting plate 17. During this swinging process, the fixed shaft 20 slides within the movable groove 19 of the adjusting rod 18, thus constraining the movement trajectory of the adjusting rod 18 and providing an additional fulcrum. The linear up-and-down movement of the insert rod 8 is decomposed and converted into the approximately horizontal linear opening and closing movement of the two clamping plates 7, resulting in high transmission efficiency and a well-defined motion relationship.

[0058] The locking mechanism is used to lock the state of the steel after the clamping mechanism has finished clamping it, preventing accidental release. The locking mechanism mainly consists of a lifting plate 12, at least one locking rod 15, an elastic reset member, and an operating button. Inside the fixing block 3, above or to the side of the two side slots 6, there is a vertical lifting groove 11. The lifting plate 12 slides up and down within this lifting groove 11. In this embodiment, the elastic reset member is two telescopic springs 13, which are vertically installed between the top inner wall of the lifting groove 11 and the top of the lifting plate 12. In its natural state, the elastic force of the telescopic springs 13 acts downward on the lifting plate 12, attempting to keep it in the lower position of the lifting groove 11. One or more locking rods 15 are vertically fixed to the bottom of the lifting plate 12 and rise and fall together with the lifting plate 12. At the top of the vertical section of each clamping plate 7, multiple locking holes 14 are machined at intervals along its sliding direction (vertical direction). The locking holes 14 can be round, square, or other shaped grooves. When the clamping plate 7 moves to the appropriate position to clamp the square steel, one of its top locking holes 14 will be precisely aligned with the lower end of the locking rod 15 located above it. Driven by the telescopic spring 13, the lifting plate 12 moves the locking rod 15 downwards, causing the lower end of the locking rod 15 to insert into the locking hole 14. Since the locking rod 15 is fixed to the lifting plate 12, and the lifting movement of the lifting plate 12 is restricted by the lifting groove 11, the locking rod 15 inserted into the locking hole 14 forms a mechanical obstacle, preventing the clamping plate 7 from moving horizontally, thus locking the position of the clamping plate 7. The operating button, i.e., the operating button 5 located on the outer wall of the fixing block 3, has its inner part firmly connected to the internal lifting plate 12 via a sliding groove 4. When it is necessary to unlock the device for disassembly or adjustment, the operator pushes the operating button 5 upward with their finger. The operating button 5 causes the lifting plate 12 to compress the telescopic spring 13 and move upward, thereby completely pulling the locking rod 15 out of the locking hole 14 of the clamping plate 7. Once the locking rod 15 is disengaged, the clamping plate 7 is no longer restricted in its horizontal direction and can move freely, thus releasing the clamping state.

[0059] Furthermore, multiple locking rods 15 of varying lengths are located at the bottom of the lifting plate 12. The purpose of these different lengths is to provide varying locking depths. Since the top of the clamping plate 7 has multiple locking holes 14 at different heights, and the height of the top of the clamping plate 7 relative to the fixing block 3 may vary slightly when clamping different thicknesses or under different clamping forces, the varying lengths of the locking rods 15 ensure that when the lifting plate 12 is pressed down, at least one locking rod 15 can always be effectively and deeply inserted into the currently aligned locking hole 14, ensuring reliable locking. For example, a longer locking rod 15 may be used for locking when the clamping plate 7 is at its maximum clamping stroke (i.e., the top position is relatively low), while a shorter locking rod 15 is used for locking when the clamping plate 7 is clamping thinner square steel or is not fully clamped (i.e., the top position is relatively high). This stepped locking design enhances adaptability to different working conditions and installation states, avoids locking failures or insufficient locking depths due to unsuitable lengths of individual locking rods, and improves the versatility and reliability of the device.

[0060] Furthermore, a magnetic block 23, such as a permanent magnet, is embedded in the upper side wall of the insertion rod 8. Correspondingly, inside the fixing block 3, specifically at the position on the inner wall of the installation channel corresponding to the movement trajectory of the magnetic block 23, an adsorption part made of magnetically conductive material is provided. This adsorption part can be an embedded magnetically conductive metal sheet. The working process is as follows: when the operator presses down on the insertion rod 8, causing its lower end to insert into the mounting hole of the square steel and reach near the predetermined clamping position, the magnetic block 23 on the insertion rod 8 will move to a position very close to or in contact with the adsorption part inside the fixing block 3. At this time, a magnetic attraction force is generated between the magnetic block 23 and the adsorption part. Although the magnetic attraction force is insufficient to counteract the force of manual unlocking or the holding force of clamping, it can temporarily hold the insertion rod 8 before the locking mechanism fully locks, preventing the insertion rod 8 from accidentally springing upwards due to its own weight or slight disturbance. This facilitates single-person installation operation, making the installation process smoother and more stable, eliminating the need to constantly hold the insertion rod 8 in place.

[0061] To enhance the tightness, uniformity, and shock absorption of the clamping mechanism, an elastic pressure pad assembly is provided on the upper surface of the horizontal section of each clamping plate 7. The elastic pressure pad assembly mainly consists of a compression plate 9 and a compression spring 10. The compression plate 9 is positioned above the horizontal section of the clamping plate 7, maintaining a certain gap between its bottom surface and the horizontal section. One or more compression springs 10 are installed in this gap, with the upper end of the spring pressing against the lower surface of the compression plate 9 and the lower end fixed to the upper surface of the horizontal section of the clamping plate 7. When the horizontal section of the clamping plate 7 closes and supports the bottom of the square steel, the compression plate 9 first contacts the bottom surface of the square steel. As the clamping plate 7 continues to close or the locking mechanism presses down, the compression spring 10 is compressed. The compressed spring 10 generates a continuous upward elastic force, which acts on the bottom surface of the square steel through the compression plate 9. The elastic pressure first compensates for any slight unevenness or corrosion on the bottom surface of the square steel, making the pressure on the contact surface more uniform and increasing static friction, thereby improving the anti-slip capability. Secondly, the elasticity of the spring can absorb and buffer the instantaneous impact force caused by vibration of the transmission pipe, wind sway, etc., avoiding the loosening of the fixed structure due to rigid impact. Finally, the spring makes the clamping action lighter, reducing the stringent requirements for positional accuracy during installation and making it easier to achieve tight clamping.

[0062] To ensure the stability and straightness of the insertion rod 8 during its up-and-down movement and to prevent it from tilting or jamming due to uneven force, one or more limiting rods 21 are installed on the inner wall of the mounting channel of the fixing block 3. The limiting rod 21 is vertically fixed, with one end of it fixed to the internal structure of the fixing block 3. Through holes are correspondingly provided on the top of the insertion rod 8 and on the shaft plate 16 fixed to the top of the insertion rod 8. The limiting rod 21 passes through the through holes on the shaft plate 16 and the top of the insertion rod 8 (or vice versa). When the insertion rod 8 and the shaft plate 16 move up and down, they slide along the axial direction of the limiting rod 21. The limiting rod 21 provides precise guidance, ensuring that the movement trajectory of the insertion rod 8 remains strictly vertical and does not deflect, preventing deviation of the hinge point movement trajectory of the adjusting rod 18, which could lead to transmission problems, jamming, or additional wear. Simultaneously, the limiting rod 21 also indirectly restricts the rotation of the insertion rod 8 around its own axis, maintaining the directional consistency of the entire mechanism.

[0063] In this device, the transmission pipe 1 is positioned on the upper surface of the fixing block 3. The top of the fixing block 3 is typically designed with an arc-shaped recess or semi-enclosed groove, the shape of which matches the outer diameter of the transmission pipe 1. This securely supports the transmission pipe 1, preventing it from rolling off and avoiding excessive clamping force that could cause deformation. The fixing block 3 forms a physical spacer between the transmission pipe 1 and the underlying metal square steel. In summer or under direct sunlight, the surface temperature of the metal square steel of the enclosure can rise significantly. If the transmission pipe 1 directly contacts the high-temperature square steel, the plastic or rubber material of the pipe may age faster, soften, or even deform, affecting its lifespan and pressure resistance. Simultaneously, the high temperature may also transfer to the water inside the pipe, affecting the spraying effect to some extent. The spacer provided by the fixing block 3 effectively blocks the main path of heat transfer from the square steel to the transmission pipe 1, providing thermal insulation and improving the durability and reliability of the device in harsh environments.

[0064] In this embodiment, the fixing block 3 is preferably made of metal, such as cast iron, cast steel, or aluminum alloy formed by casting, forging, or machining. Using metal provides extremely high mechanical strength, rigidity, and impact resistance, sufficient to withstand the weight of the transmission pipe 1, the water, and external loads such as wind loads and accidental collisions, ensuring long-term use without deformation or cracking. Metal also has good weather resistance and corrosion resistance, adapting to the harsh environment of the construction site, including sun, rain, and dust erosion. Furthermore, the metal block itself has a certain weight, which helps increase the stability of the entire fixing assembly on the square steel, reducing swaying. Although the cost of metal may be higher than that of plastic, its advantages in reliability, lifespan, and load-bearing capacity are crucial for dust suppression devices that require long-term stable operation. Of course, under the premise of meeting strength requirements, high-strength engineering plastics may also be considered for manufacturing the fixing block 3 in some embodiments to reduce weight and cost, but metal remains the preferred option to ensure the highest reliability.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
