Remote control type automatic opening and closing earthwork hopper device

Abstract

According to the remote control type automatic opening and closing earthwork hopper device, when the remote control type automatic opening and closing earthwork hopper device receives a hopper closing instruction, a control module sends out an electric signal to drive a locking assembly to act, so that the locking assembly is locked with a fixed position on a bottom plate. At the moment, the bottom plate is fixed to the closed position, and the hopper is in a closed state and can be used for loading or transporting earthwork. And when the remote control type automatic opening and closing earthwork hopper device receives an instruction of opening the hopper, the control module sends out an electric signal again to drive the locking assembly to act, so that the locking assembly is unlocked from the fixed position. After unlocking, due to the fact that the bottom plate is rotationally connected with the side plates, the bottom plate can rotate under the action of gravity or mechanical force, and therefore the hopper is opened, and earthwork is discharged. Through remote control and automatic control, manual hook unlocking and locking operation is avoided, the risk that personnel are exposed in a hoisting area is remarkably reduced, and the risk of high-altitude operation or operation in a narrow space is reduced.

Description

Technical Field

[0001] This application relates to the field of construction, and more particularly to a remote-controlled automatic opening and closing earthwork hopper device. Background Technology

[0002] Deep foundation pit earthwork refers to the process of excavation and treatment of earthwork in deep foundation pit engineering. Earthwork engineering is a fundamental part of deep foundation pit construction, involving multiple aspects such as soil excavation, transportation, stockpiling, or disposal.

[0003] The typical earthwork excavation construction sequence is as follows: preparatory work (site leveling, drainage layout, etc.), layered earthwork excavation, simultaneous construction of support structures, earthwork transportation and removal.

[0004] For deep foundation pits, the "layered excavation and segmented support" method is usually adopted, in which the soil is excavated layer by layer while the foundation pit support structure is installed to ensure the stability of the foundation pit.

[0005] After the demolition of the existing temporary roads in the foundation pit, the limited space around the pit may not provide enough space to build alternative transportation channels. This means that the handling and transport of excavated soil can only rely on vertical transportation equipment (such as tower cranes and hoists).

[0006] When using existing earthmoving hoppers to transport earth, the hoppers have an opening and closing side, and are secured and disassembled using hooks and release hooks. During disassembly and installation, personnel must approach the hopper to operate the hooks, meaning they are exposed to the hoisting area. In the event of equipment failure, hopper shaking, or earth overflow, operators may be injured, especially at height or in confined spaces where the risk is even greater.

[0007] When hoisting earth, the hopper may be affected by external factors (such as wind or mechanical swaying), which increases the uncertainty and danger for personnel during the operation.

[0008] Secondly, during the unhooking and locking of the hopper, improper design or operation of the hopper opening and closing mechanism may lead to uneven loading of the earthwork, affecting the stability of the hoisting. If the earthwork tilts or falls during hoisting, it will not only affect construction efficiency but also pose a risk of injury from falling objects. Summary of the Invention

[0009] In view of this, it is necessary to provide a remote-controlled automatic opening and closing earthwork hopper device to solve the above problems.

[0010] An embodiment of this application provides a remote-controlled automatic opening and closing earthmoving hopper device, comprising:

[0011] The hopper includes a side plate and a bottom plate, one end of the bottom plate is rotatably connected to the side plate, and the other end of the bottom plate is provided with a fixed position;

[0022] In at least one embodiment of this application, the remote-controlled automatic opening and closing earthmoving hopper device further includes:

[0023] The third hinge has one end located on the side plate and the other end hinged to the middle of the locking arm.

[0024] In at least one embodiment of this application, the locking position extends along the length direction perpendicular to the locking arm to form a locking portion;

[0025] The fixing position is equipped with a fixing post;

[0026] When the locking part is locked with the fixing post, the projected area of ​​the locking part blocks the projected area of ​​the fixing post in the vertically upward direction.

[0028] In at least one embodiment of this application, the distance from the first hinge to the locking position is denoted as c, and the distance from the second hinge to the locking position is denoted as d, satisfying the relationship: c < d.

[0029] In at least one embodiment of this application, the remote-controlled automatic opening and closing earthmoving hopper device further includes:

[0030] The hinge has one end located on the side plate and the other end located on the bottom plate.

[0034] The power supply is located on the control box;

[0035] A control circuit board is located on the control box and is electrically connected to the power supply and the locking assembly.

[0036] The remote-controlled automatic opening and closing earthwork hopper device of this embodiment will have at least the following beneficial effects:

[0039] When the remote-controlled automatic opening and closing earthmoving hopper device receives the instruction to open the hopper, the control module sends an electrical signal again to drive the locking component to unlock it from the fixed position.

[0040] After unlocking, the bottom plate, due to its rotating connection with the side plates, can rotate under the action of gravity or mechanical force, thereby opening the hopper and unloading the excavated soil.

[0041] Remote and automated control eliminates the need for manual unhooking and locking, significantly reducing the risk of personnel exposure in the hoisting area and minimizing the dangers of working at heights or in confined spaces.

[0042] Automated control enables rapid opening and closing of the hopper, reducing manual operation time. Remote control also allows for continuous operation, improving the efficiency of earthwork transportation and unloading. Attached Figure Description

[0053] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0054] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0055] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] An embodiment of this application provides a remote-controlled automatic opening and closing earthmoving hopper 110 device 100, comprising:

[0057] The hopper 110 includes a side plate 111 and a bottom plate 112. One end of the bottom plate 112 is rotatably connected to the side plate 111, and the other end of the bottom plate 112 is provided with a fixed position 112a.

[0058] A locking assembly 120 is disposed on the side plate 111 and is rotatably connected to the side plate 111;

[0059] The control module 130 is located on the side plate 111 and is electrically connected to the locking assembly 120;

[0060] The control module 130 controls the movement of the locking component 120 to lock or unlock the locking component 120 with the fixed position 112a, thereby fixing or releasing the base plate 112.

[0061] Please refer to Figures 1-4 In this embodiment, when the remote-controlled automatic opening and closing earthwork hopper 110 device 100 receives the instruction to close the hopper 110, the control module 130 sends an electrical signal to drive the locking component 120 to lock it with the fixed position 112a on the base plate 112.

[0062] At this time, the bottom plate 112 is fixed in the closed position, and the hopper 110 is in a closed state, which can be used to load or transport earth.

[0063] When the remote-controlled automatic opening and closing earthwork hopper 110 device 100 receives the instruction to open the hopper 110, the control module 130 sends an electrical signal again to drive the locking component 120 to unlock it from the fixed position 112a.

[0064] After unlocking, the bottom plate 112 can rotate under the action of gravity or mechanical force due to its rotational connection with the side plate 111, thereby opening the hopper 110 and unloading the soil.

[0065] Remote and automated control eliminates the need for manual unhooking and locking, significantly reducing the risk of personnel exposure in the hoisting area and minimizing the dangers of working at heights or in confined spaces.

[0066] The automated control system enables rapid opening and closing of the hopper 110, reducing manual operation time. Remote control also allows for continuous operation, improving the efficiency of earthwork transportation and unloading.

[0067] The precise fit between the locking component 120 and the fixing position 112a of the base plate 112 ensures that the hopper 110 has high stability in the closed state, preventing soil overflow and tilting during transportation and effectively ensuring the safety and continuity of the construction process.

[0068] It should be noted that the hopper 110 is roughly a trapezoidal structure with an internal concavity, the side plate 111 is composed of four trapezoidal plates, and the bottom plate 112 is a rectangular plate.

[0069] In at least one embodiment of this application, the locking component 120 includes:

[0070] Telescopic rod 121, the fixed end of which is rotatably connected to the side plate 111;

[0071] The locking arm 122 is rotatably connected at one end to the movable end of the telescopic rod 121, and the other end is the locking position 1211. The locking arm 122 is rotatably connected to the side plate 111.

[0072] The telescopic rod 121 extends and retracts to drive the locking arm 122 to rotate, so that the locking position 1211 is locked or unlocked with the fixed position 112a.

[0073] In at least one embodiment of this application, the remote-controlled automatic opening and closing earthmoving hopper 110 device 100 further includes:

[0074] The first hinge 123 has one end fixed to the side plate 111 and the other end hinged to the fixed end of the telescopic rod 121;

[0075] The second hinge 124 has one end fixed to the movable end of the telescopic rod 121, and the other end hinged to the end of the locking arm 122 away from the locking position 1211.

[0076] In at least one embodiment of this application, the remote-controlled automatic opening and closing earthmoving hopper 110 device 100 further includes:

[0077] The third hinge 125 has one end located on the side plate 111 and the other end hinged to the middle of the locking arm 122.

[0078] In at least one embodiment of this application, the locking position 1211 extends along the length direction perpendicular to the locking arm 122 to form a locking portion;

[0079] The fixed position 112a is provided with a fixed post 113;

[0080] When the locking part is locked with the fixing post 113, the projected area of ​​the locking part blocks the projected area of ​​the fixing post 113 in the vertically upward direction.

[0081] Please refer to Figures 1-4 In this embodiment, the control module 130 sends a signal to retract the telescopic rod 121. The movement of the telescopic rod 121 causes the locking arm 122 to rotate through the second hinge 124, ultimately aligning and locking the locking part on the locking position 1211 with the fixing post 113 on the fixing position 112a.

[0082] When the locking part successfully locks with the fixing column 113, the bottom plate 112 is fixed in the closed state, ensuring that the hopper 110 will not open during hoisting.

[0083] When it is necessary to dump earth, the control module 130 issues a command, and the telescopic rod 121 moves in the opposite direction. The movable end of the telescopic rod 121 extends, causing the locking arm 122 to rotate in the opposite direction through the second hinge 124 and the third hinge 125, thereby unlocking the connection between the locking part and the fixed column 113.

[0084] After unlocking, the base plate 112 falls freely or opens under the action of gravity, and the hopper 110 is in the open state, allowing the excavated soil to be unloaded.

[0085] By cooperating with the telescopic rod 121, the locking and unlocking process is automated and remotely controlled, avoiding the risk of operators having to approach the hopper 110 for manual operation and greatly improving the safety of operation.

[0086] The first hinge 123, the second hinge 124, and the third hinge 125 enable the locking arm 122 to remain stable when under force and convert the linear motion of the telescopic rod 121 into the rotational motion of the locking arm 122, ensuring precise engagement between the locking position 1211 and the fixed post 113.

[0087] The locking part and the fixing column 113 ensure the stability of the connection by blocking the projected area. Even if there is some vibration or shaking in the construction environment, the base plate 112 can remain in the closed state to prevent the soil from overflowing.

[0088] Automated control reduces operator involvement and significantly improves the efficiency of the 110-type hopper opening and closing mechanism, making it suitable for continuous earthmoving operations. At the same time, it reduces the labor intensity of manual operations and enhances the overall operational efficiency of the construction site.

[0089] It should be noted that the locking position 1211 extends along the length of the locking arm 122 to form a locking part, which is used to lock with the fixing post 113 on the fixing position 112a. This allows the locking part to abut against the fixing post 113 in the vertical direction and lock together.

[0090] The fixing post 113 is located on the fixing position 112a. When the locking part is locked with it, the projected area of ​​the locking part can block the projected area of ​​the fixing post 113, thereby achieving a stable locking effect.

[0091] The locking mechanism and fixing post 113 ensure that the bottom plate 112 of the hopper 110 is firmly fixed in the closed position during hoisting, preventing soil from tilting or overflowing. Their shape and extension direction further guarantee stability in the vertical direction.

[0092] It should be further explained that after locking, the locking arm 122 and the locking part will abut against the circumferential surface of the fixing column 113. The force on the base plate 112 will be directly applied to the locking part through the fixing column 113. The locking arm 122 and the locking part directly block the fixing column 113 in the radial direction, and in the vertical upward direction, the projected area of ​​the locking part blocks the projected area of ​​the fixing column 113, so as to firmly fix the fixing column 113 on the locking part, so that the side plate 111 and the base plate 112 form a space for accommodating earthwork.

[0093] It should be further explained that the telescopic rod 121 is a hydraulic rod; the locking arm 122 is roughly L-shaped; the first hinge 123, the second hinge 124 and the third hinge 125 are all rotatable hinges; the fixing post 113 is a circular column, and the axial direction of the fixing post 113 is parallel to the plane of the base plate 112 when locked; the locking part is plate-shaped.

[0094] In at least one embodiment of this application, the length of the locking part is a, and the diameter of the fixing post 113 is b, satisfying the relationship: 2b>a>b.

[0095] Please refer to Figures 1-4 In this embodiment, the locked state is as follows:

[0096] When the control module 130 drives the telescopic rod 121 to push the locking arm 122, the locking part gradually approaches the fixed post 113. Since the length a of the locking part is greater than the diameter b of the fixed post 113, when the locking part approaches the fixed post 113, it can smoothly surround and lock the fixed post 113, forming a stable locking state.

[0097] In the locked state, the length of the locking part ensures that it can completely cover the projected area of ​​the fixed column 113, thereby ensuring the stability of the bottom plate 112 of the hopper 110 when closed, and preventing it from being unlocked due to vibration or shaking during the pit operation.

[0098] Unlocked status:

[0099] When the control module 130 issues an unlocking instruction and the telescopic rod 121 moves in the reverse direction to drive the locking arm 122 to rotate, the locking portion gradually disengages from the fixed column 113. Since the length of the locking portion is appropriate (satisfying a > b and a < 2b), there is sufficient freedom during unlocking and it can smoothly disengage from the fixed column 113, achieving rapid unlocking and thus opening the bottom plate 112.

[0100] This ensures the flexibility and efficiency of the operation process, and there will be no jamming or instability caused by the excessive or insufficient length of the locking portion.

[0101] In at least one embodiment of the present application, the distance from the first hinge 123 to the locking position 1211 is denoted as c, and the distance from the second hinge 124 to the locking position 1211 is denoted as d, satisfying the relational expression: c < d.

[0102] Please refer to Figures 1-4 , in this embodiment, when the control module 130 drives the telescopic rod 121 to retract, the fixed end of the telescopic rod 121 is fixed to the side plate 111 through the first hinge 123, providing a fulcrum. Due to the lever relationship of c < d, when the movable end of the telescopic rod 121 pulls the locking arm 122 inward, the locking arm 122 rotates around the third hinge 125.

[0103] Because d (the distance from the second hinge 124 to the locking position 1211) is greater than c, the longer lever arm can cause sufficient rotation of the end of the locking arm 122 (i.e., the locking position 1211), so that the locking portion can completely surround and tightly hold the fixed column 113, achieving a firm lock.

[0104] When the control module 130 issues an unlocking instruction and extends the telescopic rod 121, the movable end of the telescopic rod 121 pushes the locking arm 122 outward, causing it to rotate in the reverse direction around the third hinge 125.

[0105] Since the distance (d) from the second hinge 124 to the locking position 1211 is long, the end of the locking arm 122 can quickly and smoothly disengage from the fixed column 113, achieving a rapid and smooth unlocking action, ensuring the flexibility and accuracy of the unlocking process.

[0106] In at least one embodiment of the present application, the remotely controlled automatic opening and closing earthwork hopper 110 device 100 further includes:

[0107] A hinge 140, one end is provided on the side plate 111, and the other end is provided on the bottom plate 112.

[0108] Please refer to Figures 1-4In this embodiment, when the control module 130 sends an unlock signal, the locking component 120 unlocks, one end of the base plate 112 is no longer fixed, and the base plate 112 rotates around the hinge 140. Due to the fulcrum effect of the hinge 140, the base plate 112 hangs freely under the action of gravity, thereby opening the hopper 110 and dumping the soil.

[0109] This ensures that the base plate 112 can rotate smoothly when opened and stay on a controlled trajectory, without irregular swaying or loss of control.

[0110] In at least one embodiment of this application, a lifting hole 111a is provided at one end of the side plate 111 away from the bottom plate 112, and the lifting hole 111a is used to fix it to an external lifting device.

[0111] Please refer to Figures 1-4 In this embodiment, the main function of the lifting hole 111a is to connect with the lifting equipment, thereby realizing the vertical lifting, movement and positioning of the hopper 110. By connecting the hook or connector of the lifting equipment to the lifting hole 111a, the hopper 110 can be safely lifted and kept balanced.

[0112] The hooks or connectors of the hoisting equipment are fixed to the side plate 111 of the hopper 110 through the lifting hole 111a, ensuring that the hopper 110 is safely connected to the hoisting equipment. At this time, the lifting hole 111a serves as the force-bearing point of the entire hopper 110, and the hopper 110 can be lifted vertically.

[0113] Under the action of the hoisting equipment, the hopper 110 is vertically lifted or moved. The position of the lifting hole 111a is far away from the bottom plate 112, ensuring that the hopper 110 is in a balanced state during hoisting. At the same time, since the lifting hole 111a is located at the top of the side plate 111, the bottom plate 112 can remain in a free state throughout the hoisting process, providing space for subsequent opening and closing operations.

[0114] After being hoisted to the designated location, the hopper 110 can be positioned and the earthwork dumping operation can be carried out. The fixing of the lifting hole 111a to the hoisting equipment ensures that the hopper 110 is not affected by external forces during the dumping process and remains stable.

[0115] After the earthwork dumping is completed, the hoisting equipment returns the hopper 110 to its starting position through the lifting hole 111a and continues the subsequent operations.

[0116] It should be further noted that the lifting hole 111a is a circular through hole.

[0117] It should be noted again that one end of the first hinge is welded to the side plate, and the other end is fixed to one end of the telescopic rod using bolts or other fasteners; both ends of the second hinge are fixed to the telescopic rod and the locking arm using bolts or other fasteners; one end of the third hinge is welded to the side plate, and the other end is fixed to the telescopic rod using bolts or other fasteners; the fixing post is cylindrical.

[0118] In at least one embodiment of this application, the control module 130 includes:

[0119] The control box 131 is located on the side plate 111;

[0120] Power supply 132 is located on the control box 131;

[0121] The control circuit board 133 is located on the control box 131 and is electrically connected to the power supply 132 and the locking component 120.

[0122] Please refer to Figures 1-4 In this embodiment, the control box 131 is mounted on the side plate 111 and serves as the carrier of the entire control module 130, used to house and protect electrical components such as the power supply 132 and the control circuit board 133.

[0123] The power supply 132 is located inside the control box 131 and provides power to all electrical components of the control module 130. It ensures that the control circuit board 133 and the locking assembly 120 connected to it can function properly.

[0124] The control circuit board 133 is located inside the control box 131 and is electrically connected to the power supply 132 and the locking component 120. The control circuit board 133 is responsible for receiving external commands (such as remote control signals), processing information, and sending commands to the locking component 120 to perform opening and closing operations.

[0125] The hooks or connectors of the hoisting equipment are fixed to the side plate 111 of the hopper 110 through the lifting hole 111a, ensuring that the hopper 110 is safely connected to the hoisting equipment. At this time, the lifting hole 111a serves as the force-bearing point of the entire hopper 110, and the hopper 110 can be lifted vertically.

[0126] Under the action of hoisting equipment, hopper 110 is vertically lifted or moved.

[0127] The remote-controlled automatic opening and closing earthmoving hopper 110 device 100 is placed on the soil surface to be loaded. Then, the weight of the device 100 presses down, naturally closing the bottom plate 112 and side plate 111. After closing, the control circuit board 133 is activated, sending a locking signal. The telescopic rod 121 shortens, pushing the locking arm 122 to rotate. The locking arm 122 rotates until it engages with the fixed column 113, pressing down on the bottom plate 112 and completing the fixation of the bottom plate 112. Then, the hoisting device suspends the device above the loading and unloading vehicle, so that the bottom plate 112 is attached to the truck bed. The control circuit board 133 is activated, sending an unlocking signal, driving the telescopic rod 121 to extend, causing the locking arm 122 to rotate. The locking part of the locking arm 122 disengages from the fixed column 113, lifting the hopper 110 and completing the unloading. This eliminates the need for manual hooking and unhooking, and enables remote opening and closing, improving soil removal efficiency and reducing safety risks.

[0128] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
