Description

Technical Field

[0001] This application relates to the technical field of material stacking equipment, and in particular to an adjustable spray boom device for stacking. Background Technology

[0002] Stacking operations are common logistics and warehousing activities in scenarios such as yards, ports, and mines. These scenarios typically require handling large volumes of goods, including bulk cargo, containers, and steel. To improve operational efficiency, reduce labor costs, and improve the working environment, specialized stacking equipment is usually required. Efficient stacking equipment can reduce manual labor intensity, lower operating costs, and thus improve the efficiency of the entire logistics and production process.

[0003] In related technologies, dust suppression and covering of material stacks are achieved through a single boom in the stacking equipment. However, it is impossible to uniformly and effectively carry out dust suppression and covering operations for stacks of different shapes and areas. Therefore, a device is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an adjustable spraying boom device for stacking.

[0005] The adjustable spray boom device for stacking provided in this application adopts the following technical solution: An adjustable spray boom device for stacking, comprising:

[0006] The base includes two parallel guide rails spaced apart;

[0007] A vehicle frame, which is slidably connected to the base via the guide rail;

[0008] Two boom bodies are spaced parallel to each other and fixedly connected to the vehicle frame. Each boom body includes a column and a boom. The column is fixedly connected to the vehicle frame, and the boom is movably connected to the column. The vertical projection length of the boom on the stack is greater than the width of the stack. The vehicle frame is used to drive the boom bodies to move horizontally along the guide rails.

[0009] The adjustment mechanism includes a winch, pulleys, and a cable. The winch is fixedly installed on the column. Two pulleys are located at the top of the column and near the middle of the boom. The cable is configured to cooperate with the pulleys and its two ends are connected to the winch and the ends of the boom away from the column, respectively. The adjustment mechanism is used to adjust the relative angle between the boom body and the vehicle frame body.

[0010] By adopting the above technical solution, the two spaced parallel guide rails of the base allow the vehicle frame to slide stably. The vehicle frame drives the boom to move horizontally along the guide rails, which facilitates the adjustment of the boom's position above the stack. The two spaced parallel booms increase the coverage of the stacking operation, and the projected length of the boom is greater than the width of the stack, making the stacking operation more flexible. The adjustment mechanism, through the cooperation of winch, pulley and cable, can adjust the relative angle between the boom and the vehicle frame to meet the stacking operation requirements of different height differences.

[0011] Preferably, the columns are connected by three tie rods, and the arm includes three parallel main beams and secondary beams. The main beams form an equilateral triangular structure with the perimeter of the triangle gradually decreasing in the direction away from the columns. The secondary beams are fixedly arranged between the main beams and form a triangular structure between adjacent secondary beams.

[0012] By adopting the above technical solution, the stability of the boom is enhanced by setting three tie rods to connect the columns. The three main beams of the boom form an equilateral triangle structure with a gradually decreasing perimeter. Combined with the secondary beams, they form multiple triangular structures, which further improves the strength and stability of the boom.

[0013] Preferably, the frame includes two support legs corresponding to the guide rail and a mounting platform. The support legs are slidably connected to the guide rail, and the column is fixedly connected to the mounting platform.

[0014] By adopting the above technical solution, the outriggers of the vehicle frame are slidably connected to the guide rail, which allows the vehicle frame to drive the boom to move horizontally along the guide rail, thus realizing the sliding of the equipment on the base; the mounting platform is used to fix the column, so that the boom is stably connected to the vehicle frame.

[0015] Preferably, it also includes a dust suppression device, which includes a water storage tank disposed in the installation platform and a water distribution pipe connected to the water storage tank. The water distribution pipe passes through the column and is fixed parallel to the boom. The water distribution pipe is provided with a plurality of nozzles along its length and a spray gun is connected to one end away from the column.

[0016] By adopting the above technical solution, water is supplied by the water storage tank in the installation platform, and the water distribution pipe passes through the column and is fixed parallel to the boom. With the help of the nozzles and spray guns on it, dust can be reduced in the stacking operation area, reducing dust and improving the working environment.

[0017] Preferably, the outrigger includes a bracket, a roller mechanism, and an anchoring mechanism. Two roller mechanisms are provided and fixedly connected to the bracket. The anchoring mechanism is fixedly provided on one of the roller mechanisms and cooperates with the base to fix the outrigger.

[0018] By adopting the above technical solution, the outrigger is equipped with a bracket, a roller mechanism and an anchoring mechanism. The two roller mechanisms are fixed on the bracket, which allows the frame to slide smoothly on the guide rail. The anchoring mechanism cooperates with the base to fix the outrigger, improve the stability of the equipment during operation and prevent the frame from moving randomly and affecting the stacking operation.

[0019] Preferably, buffer components are fixedly connected to the opposite ends of the roller mechanism, and stop plates are provided at both ends of the guide rail, with the stop plates fixedly installed on the base.

[0020] By adopting the above technical solution, stop plates are set at both ends of the guide rail on the base, and buffer components are fixedly connected to the opposite ends of the roller mechanism. This can prevent the frame from moving out of the guide rail range due to excessive movement during the horizontal movement of the frame body and the boom body along the guide rail. The buffer components can reduce the impact force when the roller mechanism collides with the stop plates, protecting the equipment from damage.

[0021] Preferably, the roller mechanism includes two parallel rail clamps and a drive motor connected to one of the rail clamps, the rail clamps being tightly fitted with the guide rail.

[0022] By adopting the above technical solution, the roller mechanism is equipped with two parallel rail clamps and a drive motor connected to one of the rail clamps, which can effectively realize the sliding action of the vehicle frame on the guide rail. The drive motor provides power to the rail clamp, so that the rail clamp clamps the guide rail to stably and reliably drive the vehicle frame to move.

[0023] Preferably, the anchoring mechanism includes a mounting housing, a rotating shaft, a rotating rod, a connecting rod, and pins. The mounting housing is fixedly connected to the roller mechanism. The rotating shaft passes through the mounting housing. Two rotating rods are provided and rotatably connected to both ends of the rotating shaft. Two connecting rods are provided and rotatably connected to the ends of the rotating rods away from the rotating shaft. Two pins are provided and rotatably connected to the ends of the connecting rods away from the rotating rods. The side wall of the mounting housing near the pins is provided with a positioning groove, and the pins pass through the positioning groove. Limiting grooves are provided parallel to each other on both sides of the guide rail, and the limiting grooves correspond to the pins.

[0024] By adopting the above technical solution, the base guide rail allows the frame to slide, the frame drives the boom to move horizontally, the adjustment mechanism can adjust the relative angle between the boom and the frame, the outriggers move on the guide rail through the roller mechanism, the mounting housing of the anchoring mechanism is fixed on the roller mechanism, and the rotating rod, connecting rod and pin cooperate to allow the pin to be inserted into the limiting grooves on both sides of the guide rail to fix the outriggers and enhance the stability of the equipment during operation.

[0025] Preferably, a support frame is fixedly connected to the end of the extension arm away from the column, and a traveling wheel is connected to the end of the support frame near the ground. The traveling wheel is connected to a synchronous motor, and the synchronous motor is fixedly installed on the support frame.

[0026] By adopting the above technical solution, a support frame with traveling wheels and a synchronous motor are installed at the end of the boom away from the column. This enhances the stability of the boom during stacking operations, improves the reliability of equipment operation, makes the boom move more smoothly and accurately, reduces swaying and deviation, and enables synchronous drive of the traveling wheels through the synchronous motor, ensuring coordination during boom movement and further improving the equipment's working efficiency and operational accuracy.

[0027] Preferably, it also includes a control box, and the winch, the drive motor and the synchronous motor are all electrically connected to the control box.

[0028] By adopting the above technical solution, the operation of the winch, drive motor and synchronous motor can be uniformly controlled by the control box, realizing coordinated control of the relative angle adjustment of the boom body, the movement of the frame body and the movement of the traveling wheels at the end of the boom, improving the convenience and intelligence of equipment operation, and making the equipment operation more efficient, stable and safe.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The frame can drive the boom to move horizontally along the guide rail. The adjustment mechanism can adjust the relative angle between the boom and the frame, so that the equipment can flexibly adjust the boom angle and position, improving its adaptability to irregularly shaped stacks or special layout sites.

[0031] 2. The projected length of the boom on the stack is greater than the width of the stack, which can better cover the stacking area and help to complete the stacking operation efficiently;

Detailed Implementation

[0041] The following will be combined with the appendix Figure 1-7 The technical solutions in the embodiments of this utility model are described in further detail below. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0042] Example 1

[0043] refer to Figure 1This application provides an adjustable spray boom device for stacking, mainly applicable to dust suppression, covering, and shape scanning operations in scenarios such as stockpiles, ports, and mines. Stockpiles, ports, and mines typically involve the open-air storage of large quantities of bulk materials (such as coal, ore, grain, and sand), thus requiring dust suppression, covering, and shape scanning operations. Open-air stockpiled materials easily generate dust during wind or mechanical operations, polluting the air and affecting worker health and the surrounding environment. Meeting environmental regulations: Various countries have strict limits on industrial dust emissions; dust suppression measures (such as spraying and crusting agents) can reduce PM2.5 / PM10 emissions, avoiding fines or work stoppages. Reducing material loss: Dust dispersion leads to material loss; dust suppression can improve resource utilization.

[0044] Covering (for rain protection, wind protection, and oxidation prevention): Materials such as coal and grain are prone to deterioration or clumping when exposed to water; tarpaulins prevent moisture penetration. Reducing wind impact: Strong winds can scatter lightweight materials (such as mineral powder and grains); covering helps maintain the shape of stacks. Inhibiting oxidation reactions: Some materials (such as sulfur concentrate) will oxidize and generate heat when exposed for extended periods; covering can slow down the chemical reaction.

[0045] Shape scanning refers to using radar or laser to scan the shape of a stack, accurately calculate material inventory, and optimize scheduling. Safety monitoring: Detects the risk of stack collapse (such as abnormal slope) and prevents safety accidents. Automation support: Provides real-time data for unmanned equipment (such as spraying robots and covering robotic arms) to achieve precise operations.

[0046] An adjustable spraying boom device for stacking includes a base 1, a frame 2, a boom 3, and an adjustment mechanism 4. The frame 2 is slidably connected to the base 1 via a guide rail 11 and can move horizontally along the guide rail 11 of the base 1. Two booms 3 are arranged parallel to each other at intervals and are fixedly connected to the frame 2. The frame 2 drives the booms 3 to move together. The adjustment mechanism 4 is connected to the booms 3 and is used to adjust the relative angle between the booms 3 and the frame 2. This cooperation allows the boom device to flexibly reach the stacking position and adjust the angle, better adapting to different stacking tasks.

[0047] refer to Figure 1 and Figure 4 Specifically, the base 1 includes two parallel guide rails 11 spaced 10 meters apart. The guide rails 11 are generally made of high-strength steel to ensure they can support the weight of components such as the frame 2 and boom 3. The guide rails 11 can be I-beam guide rails, which offer good guidance and load-bearing capacity; or they can be channel steel guide rails, which are relatively inexpensive and easier to install.

[0048] The frame body 2 includes two outriggers 21 corresponding to guide rails 11 and a mounting platform 22. The outriggers 21 are slidably connected to the guide rails 11, and the uprights 31 are fixedly connected to the mounting platform 22. The outriggers 21 are typically welded from steel structures to ensure their strength and stability. The mounting platform 22 is a steel frame with a steel plate platform, providing a mounting foundation for components such as the boom body 3.

[0049] refer to Figure 1 , Figure 4 and Figure 5 The outrigger 21 includes a bracket 211, a roller mechanism 212, and an anchoring mechanism 213. Two roller mechanisms 212 are provided and fixedly connected to the bracket 211. The bracket 211 is fixedly connected to the mounting platform 22 by bolts or welding. The anchoring mechanism 213 is fixedly mounted on one of the roller mechanisms 212 and cooperates with the base 1 to fix the outrigger 21. Buffer members 214, made of elastic material such as rubber, are fixedly connected to the opposite ends of the roller mechanisms 212. Stop plates 12 are provided at both ends of the guide rail 11 and are fixedly mounted on the base 1. The roller mechanism 212 includes two parallel rail clamps 2121 and a drive motor 2122 connected to one of the rail clamps 2121. The rail clamps 2121 are electric rail clamps, and the drive motor 2122 drives the rail clamps 2121 to move horizontally along the guide rail 11.

[0050] refer to Figure 1 , Figure 4 and Figure 5 The anchoring mechanism 213 includes a mounting housing 2131, a rotating shaft 2132, a rotating rod 2133, a connecting rod 2134, and a pin 2135. The mounting housing 2131 is fixedly connected to the roller mechanism 212. The rotating shaft 2132 passes through the mounting housing 2131. Two rotating rods 2133 are provided and rotatably connected to both ends of the rotating shaft 2132. Two connecting rods 2134 are provided and rotatably connected to the end of the rotating rod 2133 away from the rotating shaft 2132. Two pins 2135 are provided and rotatably connected to the end of the connecting rod 2134 away from the rotating rod 2133. The mounting housing 2131 has a positioning slot 2136 on its side wall near the pin 2135. The pin 2135 passes through the positioning slot 2136. Limiting grooves 13 are provided parallel to each other on both sides of the guide rail 11. The limiting grooves 13 are provided corresponding to the pins 2135. The limiting grooves 13 are the gaps formed after the two baffles are fixed. When it is necessary to fix the frame body 2, drive the rotating rod 2133 to rotate, and drive the pin 2135 to be inserted into the limiting groove 13 through the connecting rod 2134, thereby fixing the frame body 2.

[0051] One end of the rotating rod 2133 can be connected to a manual wrench (not shown in the figure) for manual locking or unlocking by the operator. In another embodiment, the rotating shaft 2132 can also be driven by a small geared motor (not shown in the figure) to achieve electric operation of the anchoring mechanism. Reference Figures 1-3 Two boom bodies 3 are arranged parallel to each other and fixedly connected to the vehicle frame 2. Each boom body 3 includes a column 31 and a boom 32. The column 31 is fixedly connected to the vehicle frame 2, and the boom 32 is movably connected to the column 31, with the vertical projection length of the boom 32 on the stack greater than the width of the stack. The column 31 is typically a hollow steel pipe column; this structure ensures the strength of the column 31 while reducing its own weight. The inside of the column 31 can be filled with reinforcing ribs to further improve its strength.

[0052] Reference image - Figure 3 The boom 32 includes three parallel main beams 321 and secondary beams 322. The three main beams 321 form an equilateral triangular structure with the perimeter of the triangle gradually decreasing in the direction away from the column 31. The secondary beams 322 are fixedly installed between the main beams 321, and adjacent secondary beams 322 form a triangular structure. This triangular structure has high stability and can effectively resist bending and torsional forces. The main beams 321 and secondary beams 322 can be made of aluminum alloy, which is lightweight and corrosion-resistant. The columns 31 are connected by three tie rods 5, which enhance the connection stability between the columns 31. The tie rods 5 are generally steel wire ropes or cables, which have high tensile strength. In one embodiment, a single boom 32 can cover a range of 50 meters, divided into six sections, with high spraying or covering efficiency. The overall structure is simple and lightweight, with uniform stress and small deformation, and strong wind resistance. The weight of the six-section boom is approximately 2007 kg, and the weight of the column is approximately 6507 kg.

[0053] The boom 32 can also be equipped with a 600mm wide platform walkway and a 1200mm high guardrail to facilitate equipment maintenance and repair while ensuring personnel safety. The top of the column 31 is equipped with a ladder and maintenance platform for easy inspection and maintenance of the cables.

[0054] refer to Figure 1 and Figure 2The adjusting mechanism 4 includes a winch 41, pulleys 42, and a cable 43. The winch 41 is fixedly mounted on the column 31. Two pulleys 42 are located at the top of the column 31 and near the middle of the boom 32. The cable 43 is configured to cooperate with the pulleys 42, with both ends connected to the winch 41 and the ends of the boom 32 furthest from the column 31. For example, the cable 43 can be installed at 1 / 2 and 5 / 6 of the distance from the column 31 on the boom 32. The winch 41 can be an electric winch 41, providing stable tension, or a hydraulic winch 41, which has greater driving force. The pulleys 42 are generally made of cast steel, which has high strength and good wear resistance. The cable 43 can be a steel wire rope, which has high strength and flexibility. By winding and unwinding the cable 43 with the winch 41 and changing the direction of force with the pulleys 42, the angle between the boom 32 and the column 31 can be adjusted.

[0055] refer to Figures 1-3 A stacking adjustable spray boom device also includes a dust suppression device 6. The dust suppression device 6 includes a water tank 61 installed within an installation platform 22 and a water distribution pipe 62 connected to the water tank 61. The water distribution pipe 62 passes through a column 31 and is fixed parallel to the boom 32. The fixing method can be achieved using pipe clamps commonly used in the field. Several nozzles 63 are spaced apart along the length of the water distribution pipe 62, and a spray gun 64 is connected to the end furthest from the column 31. A spray gun 64 with a range of 20 meters is selected to spray water mist or a crusting agent onto the stack to achieve dust suppression. The water tank 61 is generally made of plastic or stainless steel and can be connected to the water distribution pipe 62 using a water pump, as these materials have good corrosion resistance. The nozzles 63 can be atomizing nozzles, which can spray water in the form of fine droplets for better dust suppression. The spray gun 64 can be a high-pressure spray gun, which can spray water to a greater distance.

[0056] refer to Figure 1 and Figure 4 A stacking adjustable spray boom device also includes a control box 10, with a winch 41 and a drive motor 2122 electrically connected to the control box 10. The control box 10 can centrally control the operation of each motor, realizing automated operation of the equipment. The control system is used to synchronously control the movement of the chassis 2, the ground support frame 7, and the traveling wheels 8. More specifically, the control box 10 has a built-in programmable logic controller (PLC). To achieve synchronous control, both the drive motor 2122 and the synchronous motor 9 are equipped with rotary encoders to detect their actual speed and displacement. The PLC adopts a master-slave control strategy, with the drive motor 2122 of the chassis 2 as the master drive. The PLC collects its encoder signals in real time and calculates the target speed and position of the synchronous motor 9 according to the preset transmission ratio. The driver precisely controls the synchronous motor 9 to follow, thereby ensuring that the traveling wheels 8 move synchronously with the chassis 2.

[0057] In other embodiments, the boom 32 can be equipped with a scanning radar to scan the shape of the stack; and a tarpaulin support can be installed to cover the stack. When used for covering operations, a winding drum (not shown) can be installed between the two booms 32. This drum is driven by a motor and can unfold or wind up the flexible tarpaulin along a guide rail or steel cable between the two booms.

[0058] The implementation principle of the adjustable spray boom device for stacking in this embodiment is as follows: The adjustable spray boom device for stacking moves the boom body 3 horizontally to a suitable stacking position by sliding the frame body 2 on the guide rail 11 of the base 1. The adjustment mechanism 4 can flexibly adjust the angle of the boom 32 to adapt to stacking tasks of different shapes and layouts. The unique triangular structure design of the boom 32 ensures its strength and stability, and can withstand a large weight. The dust suppression device 6 can effectively reduce dust flying during stacking operations, improving the working environment. The roller mechanism 212 and anchoring mechanism 213 of the outriggers 21 make the frame body 2 easy to move and securely fixed. The control box 10 realizes the automated control of the equipment, improving work efficiency.

[0059] Example 2

[0060] refer to Figure 6 and Figure 7 Compared to Embodiment 1, the difference in this embodiment is that a support frame 7 is fixedly connected to the end of the boom 32 away from the column 31, and a traveling wheel 8 is connected to the end of the support frame 7 near the ground. The traveling wheel 8 is connected to a synchronous motor 9, which is fixedly mounted on the support frame 7. The support frame 7 is typically a steel frame structure, providing support for the traveling wheel 8. The traveling wheel 8 can be a rubber wheel, which has good shock absorption performance; or it can be a cast iron wheel, which has strong load-bearing capacity. The synchronous motor 9 enables the traveling wheel 8 to move synchronously with the frame 2, improving the stability and coordination of the equipment. The synchronous motor 9 is electrically connected to the control box 10, and the synchronous motor 9 and the drive motor 2122 are synchronously controlled for operation.

[0061] The implementation principle of an adjustable spraying boom device for stacking according to an embodiment of this application is as follows: the support frame 7 and the traveling wheels 8 can support the boom 32 with greater weight, and the boom 32 can be lengthened as needed to adapt to stacking of a larger area.

[0062] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
