Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a dust suppression device, demolition equipment and construction method for bridge demolition. Background Technology

[0002] In existing technologies, mist cannons or water trucks are commonly used to suppress dust during bridge demolition. However, fixed or immobile mist cannons cannot spray in real-time alongside mobile demolition equipment, resulting in delayed dust suppression. Water trucks, due to the complex environment of construction sites, often cannot approach the core demolition area during the process. These issues lead to poor simultaneous dust suppression during bridge demolition. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a dust suppression device, demolition equipment, and construction method for bridge demolition, particularly suitable for use with demolition equipment to reduce dust generation synchronously with the equipment's movement. In this invention, "dust suppression" refers to the use of methods such as spraying water mist to moisten and settle the dust inevitably generated during bridge demolition operations due to mechanical crushing, impact, and falling debris, thereby significantly reducing the diffusion and emission of dust into the surrounding environment. It should be understood that this invention aims to reduce dust pollution, not completely eliminate dust generation; the term "dust suppression" in the names of the devices, equipment, and methods of this invention should be understood in this technical sense.

[0004] The technical solution adopted in this invention is: a dust suppression device for bridge demolition, comprising a water tank configured to be detachably connected to the main body of the demolition equipment via an adjustable fixing mechanism; a pumping mechanism whose inlet pipe is connected to the inside of the water tank; and a delivery pipe connected to the outlet pipe of the pumping mechanism, wherein the delivery pipe is equipped with a nozzle.

[0005] Furthermore, the adjustable fixing mechanism includes a first clamping plate, a second clamping plate, and multiple adjusting components. The first clamping plate is connected to the main body of the dismantling equipment, the second clamping plate is disposed opposite to the first clamping plate, and the second clamping plate is movably connected to the first clamping plate through the adjusting components to clamp or release the water tank.

[0006] Furthermore, the adjustment assembly includes an adjustment screw and a matching number of adjustment nuts. The adjustment screw passes through the first clamping plate and the second clamping plate in sequence, and the adjustment nuts are threadedly connected to the adjustment screw to limit the distance between the first clamping plate and the second clamping plate.

[0007] Furthermore, at least one adjusting screw is threadedly engaged with the second clamping plate to move the second clamping plate closer to or away from the first clamping plate.

[0008] Furthermore, the adjustable fixing mechanism also includes an arc-shaped clamping plate assembly that is detachably connected to the first clamping plate and / or the second clamping plate.

[0009] On the other hand, the present invention also provides a demolition device, which includes the above-mentioned dust suppression device for bridge demolition, and also includes a demolition device body and a mechanical arm for demolition operations. The mechanical arm is connected to the demolition device body, an adjustable fixing mechanism is installed on the demolition device body, and a conveying pipe is at least partially laid along the mechanical arm.

[0010] On the other hand, the present invention also provides a construction method, comprising the following steps:

[0011] The water tank is installed on the main body of the dismantling equipment using an adjustable fixing mechanism;

[0012] Connect the inlet pipe of the pumping mechanism to the water tank;

[0013] A delivery pipe is laid along the robotic arm and connected to the outlet pipe of the pumping mechanism;

[0014] Start the pumping mechanism to deliver water to the spray nozzles.

[0015] The advantages and positive effects of this invention are: by adopting the above technical solution, synchronous spraying is achieved as the dismantling equipment moves to reduce dust and improve the timeliness of spraying; it also has the advantages of simple structure and rapid deployment.

[0027] The embodiments of the present invention will now be described with reference to the accompanying drawings. The described embodiments are only some embodiments of the invention, and not all embodiments.

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation," "connection," and "fixing" should be interpreted broadly, and can refer to direct connection, installation, or fixing, or indirect connection, installation, or fixing. The present invention does not impose any limitations in this regard.

[0030] like Figures 1 to 7 The diagram illustrates an embodiment of a dust suppression device for bridge demolition according to the present invention. It includes a water tank 1, configured to be detachably connected to the main body 9 of the demolition equipment via an adjustable fixing mechanism; a pumping mechanism 2, whose inlet pipe 21 is connected to the interior of the water tank 1; and a delivery pipe, connected to the outlet pipe of the pumping mechanism 2 and extending along the mechanical arm 10 of the demolition equipment, with nozzles 3 mounted on the delivery pipe. Preferably, the nozzles 3 are located at the end of the delivery pipe. The nozzles 3 used for spraying can move with the bridge demolition equipment and spray synchronously with the demolition operation, improving the timeliness of spraying. The structure of the nozzles 3 is existing technology, and existing general-purpose spray nozzles 3 can be used. During construction, water tanks 1 of different volumes can be flexibly selected according to the expected spraying duration, construction needs, and the load capacity of the demolition equipment, and can be quickly installed via the adjustable fixing mechanism, thereby improving the adaptability of the entire construction plan and reducing dust generation by moving synchronously with the demolition operation.

[0031] The adjustable fixing mechanism includes a first clamping plate 4, a second clamping plate 5, and multiple adjusting components. The first clamping plate 4 is connected to the main body 9 of the demolition equipment. The second clamping plate 5 is positioned opposite to the first clamping plate 4, and the second clamping plate 5 is movably connected to the first clamping plate 4 via the adjusting components to clamp or release the water tank 1. Specifically, the first clamping plate 4 is fixedly connected to the main body 9 of the demolition equipment. The second clamping plate 5 adjusts its distance from the first clamping plate 4 according to the size of the water tank 1, and together with the multiple adjusting components, forms a rectangular fixing structure for fixing the water tank 1, limiting the water tank 1 on all four sides. The adjustable fixing mechanism enables rapid fixing of the water tank 1, has a simple structure, low manufacturing cost, and allows for flexible selection of water tanks 1 of different sizes according to the work requirements of bridge demolition, better achieving the effect of reducing dust flying simultaneously with demolition operations and reducing the number of water storage cycles.

[0032] The adjustment assembly includes an adjustment screw 6 and a matching number of adjustment nuts 61. The adjustment screw 6 passes sequentially through a first clamping plate 4 and a second clamping plate 5. The adjustment nuts 61 are threadedly connected to the adjustment screw 6 to limit the distance between the first clamping plate 4 and the second clamping plate 5. In this embodiment, the first clamping plate 4 and the second clamping plate 5 have multiple insertion holes for the adjustment screw 6 to pass through. The two ends of the adjustment screw 6 are respectively screwed with adjustment nuts 61 to secure the first clamping plate 4 and the second clamping plate 5 against the first and third surfaces of the side of the water tank 1. The first clamping plate 4 and the second clamping plate 5 are arranged parallel to each other, and each adjustment screw 6 is arranged perpendicular to the first clamping plate 4. The multiple adjustment screws 6 are at least partially arranged opposite each other to limit the second and fourth surfaces of the side of the water tank 1. Preferably, the first clamping plate 4 and the second clamping plate 5 are provided with multiple insertion holes in the horizontal and vertical directions to selectively insert the adjusting screw 6. Selectively inserting the adjusting screw 6 in the vertical direction can improve the stability of fixing the water tank 1 and the applicability of water tanks 1 of different heights. Selectively inserting the adjusting screw 6 in the horizontal direction, together with the first clamping plate 4 and the second clamping plate 5 with adjustable spacing, can better improve the stability of fixing water tanks 1 of different sizes.

[0033] Preferably, it can be as follows Figure 8 As shown, at least one adjusting screw 6 is threadedly engaged with the second clamping plate 5 to move the second clamping plate 5 closer to or away from the first clamping plate 4. The insertion hole of the second clamping plate 5 has at least a portion of an internal thread adapted to the adjusting screw 6. Preferably, the first end of the adjusting screw 6 threadedly engaged with the second clamping plate 5 is connected to the drive unit to control the rotation of the adjusting screw 6. In this embodiment, the drive unit is a drive motor 8, and its output end is connected to the first end of the corresponding adjusting screw 6. The adjusting screw 6 assists in moving the second clamping plate 5, optimizing the installation steps of the water tank 1 and facilitating personnel adjustment.

[0034] Preferably, it can be as follows Figure 9As shown, the adjustable fixing mechanism also includes an arc-shaped clamping plate assembly detachably connected to the first clamping plate 4 and / or the second clamping plate 5. The detachable arc-shaped clamping plate assembly is better suited for water tanks 1 with curved outer walls (e.g., circular water tanks 1). The arc-shaped clamping plate assembly can be prefabricated as needed to fit the curved outer wall of the water tank 1. The adjustable fixing mechanism can be adjusted to accommodate water tanks 1 of different sizes or shapes, significantly improving the versatility of the device and its adaptability to different site conditions.

[0035] Preferably, the delivery pipe includes a rigid pipe section 222 laid along the robotic arm 10 of the demolition equipment, a flexible pipe section 221 located at the moving part of the robotic arm 10, and a quick connector 223 for connecting the rigid pipe section 222 and the flexible pipe section 221. In different embodiments, the water outlet pipe of the pumping mechanism 2 is connected to the corresponding rigid pipe section 222 or flexible pipe section 221, and the robotic arm 10 fixes the rigid pipe section 222 or flexible pipe section 221 of the delivery pipe through a fixed support 24. The layout and fixing method of the delivery pipe on the demolition equipment body 9 can also be flexibly selected based on the general technical knowledge of those skilled in the art, and the present invention is not limited thereto. The rigid pipe section 222 can ensure the stability of the pipeline on the robotic arm 10, and the flexible pipe section 221 adapts to the operation of the robotic arm 10.

[0036] The pumping mechanism 2 is a conventional fluid transport mechanism in the field, usually adopting the existing technology of integrating the motor and the water pump. Its specific structure and working principle are common knowledge.

[0037] On the other hand, the present invention also provides a demolition device, which includes the aforementioned dust suppression device for bridge demolition, a demolition device body 9, and a robotic arm 10 for demolition operations. The robotic arm 10 is connected to the demolition device body 9, and an adjustable fixing mechanism is installed on the demolition device body 9. A delivery pipe is at least partially laid along the robotic arm 10. A pumping mechanism 2 is installed on the demolition device body 9. The specific structure of the robotic arm 10 and the way it is movably connected to the demolition device body 9 are common knowledge. For example, a combination of an excavator and a hydraulic breaker (referred to as a "jackhammer") can be used as the demolition device, combined with the dust suppression device for bridge demolition.

[0038] On the other hand, the present invention also provides a construction method, comprising the following steps:

[0039] The water tank 1 is installed on the main body 9 of the dismantling equipment via an adjustable fixing mechanism;

[0040] Connect the water inlet pipe 21 of the pumping mechanism 2 to the water tank 1;

[0041] A delivery pipe is laid along the robotic arm 10 and connected to the outlet pipe of the pumping mechanism 2;

[0042] Start the pumping mechanism 2 to deliver water to the nozzle 3 and spray it out.

[0043] Example 1:

[0044] like Figures 1 to 7 As shown, the dust suppression device for bridge demolition includes a water tank 1, a pumping mechanism 2, and a delivery pipe. The water tank 1 is used for water storage and is typically a square or round plastic water tank. The top of the water tank 1 is equipped with an openable cover 11, which can be fastened to the water tank 1. The cover 11 has an outlet hole with a diameter that matches the water inlet pipe 21 of the pumping mechanism 2. The water outlet pipe of the pumping mechanism 2 leads water to the nozzle 3 through the delivery pipe. The nozzle 3 is installed at the mechanical arm 10 of the demolition equipment (e.g., a jackhammer) used for demolition operations to spray water synchronously with the demolition operation.

[0045] Water tank 1 is installed on the main body 9 of the dismantling equipment (such as the counterweight area of ​​the gun machine) via an adjustable fixing mechanism.

[0046] The adjustable fixing mechanism includes a first clamping plate 4, a second clamping plate 5, and multiple adjusting screws 6. The first clamping plate 4 can be fixedly connected to the main body 9 of the dismantling equipment by welding or bolting. The second clamping plate 5 is parallel to the first clamping plate 4. During installation, one side of the water tank 1 is placed against the first clamping plate 4, and then the second clamping plate 5 is placed on the other side of the water tank 1. Subsequently, multiple screws are passed through the corresponding insertion holes on the first clamping plate 4 and the second clamping plate 5 in sequence, and adjusting nuts 61 are tightened at both ends (or one end) of the adjusting screws 6, so that the first clamping plate 4, the second clamping plate 5, and the adjusting screws 6 together form an adjustable frame, fixing the water tank 1 from all sides. By selecting adjusting screws 6 of different lengths and adjusting the position of adjusting nuts 61 on the adjusting screws 6, different sizes of water tanks 1 can be accommodated. In specific implementation, multiple insertion hole arrays can be opened on the first clamping plate 4 and the second clamping plate 5 to meet the installation requirements of different sizes of water tanks 1; or, the spacing of the insertion holes opened on the first clamping plate 4 and the second clamping plate 5 conforms to the standard size of commonly used water tanks 1.

[0047] The pumping mechanism 2 is mounted on the demolition equipment body 9 by a fixing frame. The fixing frame includes opposing side plates 22 and a bottom plate 23 connecting the bottom of the two side plates 22. The side plates 22 have grooves (e.g., semi-circular) to support the pumping mechanism 2, and the bottom plate 23 is connected to the demolition equipment body 9.

[0048] The delivery pipe includes a rigid pipe section 222 (such as a stainless steel pipe) laid along the robotic arm 10 of the demolition equipment (e.g., the main arm and auxiliary arm connected sequentially on a ram machine), and a flexible pipe section 221 connected at the moving parts of the robotic arm 10 (e.g., the joint connecting the main arm and auxiliary arm). The rigid pipe section 222 and the flexible pipe section 221 are connected by a quick connector 223. The rigid pipe section 222 is connected to the robotic arm 10 by a fixed support 24. The fixed support 24 may include an angle steel and a U-bolt. The first side of the angle steel is pre-connected to the boom of the robotic arm 10 of the demolition equipment by welding or bolting. The U-bolt spans the rigid pipe section 222 (such as a stainless steel pipe) of the delivery pipe, and its two threaded rods pass downward through corresponding through holes opened on the second side of the angle steel. Nuts are screwed onto the threaded rods at both ends of the U-bolt on the upper and lower sides of the second side of the angle steel to lock it in place. By tightening the nut, the U-bolt firmly presses and fixes the rigid pipe section 222 onto the angle steel, thereby achieving a fixed connection between the conveying pipe and the robotic arm 10.

[0049] The end of the delivery pipe is connected to two pendant water curtain nozzles 3 via a universal tee connector 31 to expand the spray range. Typically, the tee connector 31 is connected to the corresponding rigid pipe section 222.

[0050] In a specific use case:

[0051] S1: Select a suitable water tank 1 based on the required spray volume and the load-bearing capacity of the demolition equipment. Securely install the water tank 1 onto the main body 9 of the demolition equipment (such as the rear of the demolition machine or a designated location) using an adjustable fixing mechanism.

[0052] S2: Install the pumping mechanism 2 at a suitable position on the dismantling equipment body 9 through its mounting bracket, and insert its pumping pipe (inlet pipe 21) through the inlet hole of the cover 11 of the water tank 1 into the water tank 1.

[0053] S3: Based on the dimensions and movement trajectory of the robotic arm 10 of the dismantling equipment, plan the delivery pipeline route. Lay stainless steel pipes (rigid pipe sections 222) along the main body 9 of the dismantling equipment and the main arm of the robotic arm 10, and fix them in sections with fixed supports 24. At the locations where the robotic arm 10 needs to move (e.g., at the connection between the main arm and the auxiliary arm), connect hoses (flexible pipe sections 221) of appropriate length through quick connectors 223.

[0054] S4: Connect the end of the stainless steel pipe to two pendant water curtain nozzles 3 via a tee connector 31.

[0055] S5: Before construction, fill water tank 1 with water. During demolition, start pumping mechanism 2, and water is sprayed from nozzle 3 through delivery pipe to form a water curtain, thereby reducing dust in real time during the crushing and demolition process.

[0056] This embodiment allows for quick adaptation to water tanks 1 of different sizes by adjusting the position of the adjusting nut 61 or replacing the adjusting screw 6. It can move synchronously with the dismantling operation to reduce dust while also flexibly selecting a suitable water tank 1 to reduce unnecessary load.

[0057] Example 2:

[0058] like Figure 8 As shown, for ease of operation, based on Embodiment 1, at least one adjusting screw 6 can be threaded into the second clamping plate 5, and a drive unit can be provided at the end of the adjusting screw 6. The drive unit can be a hand crank. In this embodiment, the drive unit is a drive motor 8, the output end of which is connected to the end of the adjusting screw 6. The shaft of the adjusting screw 6 passes through the insertion hole (through hole) of the first clamping plate 4 and is threaded into the insertion hole (threaded hole) of the second clamping plate 5. The end of the adjusting screw 6 away from the drive unit is rotatably connected to a connecting seat 62 fixed on the demolition equipment body 9 through a structure such as a bearing. In use, the water tank 1 is initially placed, and then the adjusting screw 6 is controlled to rotate. The bottom of the second clamping plate 5 contacts the demolition equipment body 9 or is guided and restricted by it to not rotate. Then, the second clamping plate 5 moves along the axial direction of the adjusting screw 6 to initially clamp the water tank 1. Adjusting nuts 61 are then installed and tightened on the other adjusting screws 6 that are not threaded into the second clamping plate 5. In this embodiment, the adjusting screw 6 is rotated by the driving unit, which realizes the quick and labor-saving adjustment of the position of the second clamping plate 5, simplifies the water tank installation steps, and makes it more flexible to use.

[0059] Example 3:

[0060] like Figure 9 As shown, based on Embodiment 1 or Embodiment 2, when a water tank 1 with an arc-shaped outer wall (e.g., a circular water tank 1) is required, an arc-shaped clamping plate assembly can be detachably installed on the first clamping plate 4 and the second clamping plate 5. The arc-shaped clamping plate assembly includes a connector 71 and an arc-shaped plate 7. The connector 71 can be U-shaped, with its horizontal portion overlapping the top of the first clamping plate 4 (or the second clamping plate 5), and its vertical portions located on either side of the first clamping plate 4 (or the second clamping plate 5). The horizontal or vertical portions of the connector 71 are fastened to the first clamping plate 4 (or the second clamping plate 5) by set screws or bolts. The arc-shaped plate 7 is fixedly connected to the side of the connector 71. The arc-shaped plate 7 is used to press against the arc-shaped outer wall of the water tank 1, and, in conjunction with the adjustable-spaced first clamping plate 4 and the second clamping plate 5, achieves stable fixation.

[0061] By adding a detachable arc-shaped clamping plate assembly, the adjustable fixing mechanism can fix both square water tank 1 and round water tank 1, which significantly improves the applicability of the device and the flexibility of material management.

[0062] This invention can effectively reduce dust during bridge demolition work. In actual operation, it can also be used in conjunction with traditional fixed or immobile dust suppression equipment to reduce spraying delays and blind spots. The adjustable fixing mechanism improves the adaptability to water tanks 1 of different sizes and shapes, and the capacity of water tank 1 can be flexibly configured according to spraying needs, which helps to reduce dust and lower the overall load of the equipment, making it particularly suitable for rapid deployment at construction sites.

[0063] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
