Description

Technical Field

[0001] The utility model relates to the technical field of material unloading equipment, in particular to a discharge port platform. Background Art

[0002] As a fast unloading equipment for trucks, hydraulic flaps have been rapidly developed due to their high unloading efficiency. They are widely used in large-scale operations such as grain, coal, feed, wood chips, and building materials.

[0003] When the cargo in the truck is dumped into the unloading pit through the hydraulic flap, in order to improve the working efficiency, a discharge port platform is generally set above the unloading pit. When the discharge port platform is closed, the truck can move forward through the discharge port platform and onto the hydraulic flap. Before the hydraulic flap dumps the truck, the discharge port platform is opened so that the cargo on the truck can be dumped into the unloading pit.

[0004] There is a lifting type discharge port platform, which includes a bottom support, a grille platform, a driving mechanism and a hinge mechanism. The grille platform is installed on the foundation, and the grille platform is supported and positioned by the bottom support below it; a driving mechanism is provided on the front and rear sides of the grille platform, and the right side of the grille platform is connected to the foundation through a hinge mechanism. The driving mechanism drives the grille platform to flip and rise around the hinge mechanism, thereby exposing the discharge pit below.

[0005] However, during the application of this type of unloading port platform, in order to avoid collision between the truck and the unloading port platform, the hydraulic flap needs to wait until the platform is fully raised before the truck can be dumped, resulting in low unloading efficiency. Utility Model Content

[0006] The main purpose of the utility model is to provide a discharge port platform, aiming to improve the unloading efficiency.

[0007] To achieve the above-mentioned purpose, the discharge port platform proposed in the present invention includes:

[0008] a platform assembly, one end of which is rotatably connected to the periphery of the discharge port; and

[0009] The driving device is arranged at the periphery of the discharge port, driving the platform assembly to rotate the platform assembly so that the platform assembly has a closed position for sealing the discharge port and an open position for entering the discharge pit.

[0010] In one embodiment, the driving device comprises:

[0011] a base assembly fixed to the periphery of the discharge port; and

[0012] The telescopic assembly has a first end and a second end relative to each other, wherein the first end is rotatably connected to the base assembly, and the second end is rotatably connected to the platform assembly. The telescopic assembly is extended and retracted so that the platform assembly switches between the closed position and the open position.

[0013] In one embodiment, the telescopic assembly is a hydraulic cylinder.

[0014] In one embodiment, the discharge port platform also includes a first limit switch, which is arranged on one side of the telescopic assembly and electrically connected to the telescopic assembly, and is used to control the working state of the telescopic assembly to keep the platform assembly in the closed position.

[0015] In one embodiment, the discharge port platform further includes a second limit switch, which is disposed on one side of the platform assembly and electrically connected to the telescopic assembly, for controlling the working state of the telescopic assembly to keep the platform assembly in the open position.

[0016] In one embodiment, the second limit switch is disposed inside the unloading pit.

[0017] In one embodiment, the platform components include:

[0018] a grille platform, one end of which is rotatably connected to the periphery of the discharge port; and

[0019] The support frame is arranged on a side of the grid platform away from the discharge pit, and the second end of the telescopic assembly is rotatably connected to an end of the support frame away from the grid platform.

[0020] In one embodiment, one support frame is provided on each of the two opposite sides of the grid platform, and each support frame is correspondingly provided with one telescopic assembly, and the two telescopic assemblies are synchronously extended and retracted.

[0021] In one embodiment, the base assembly comprises:

[0022] A seat body is provided at the periphery of the discharge port, and one end of the telescopic assembly is rotatably connected to the seat body; and

[0023] The embedded part is connected to the seat body and fixed in the concrete foundation of the periphery of the unloading pit.

[0024] In one embodiment, one end of the embedded component away from the base is bent to form an anchoring structure.

[0025] The discharge port platform in the technical solution of the present invention includes a platform assembly and a drive device. The platform assembly is rotatably connected to the periphery of the discharge port. The drive device drives the platform assembly to rotate. The platform assembly has a closed position and an open position through rotation. When the platform assembly is in the closed position, the discharge port is closed, and a truck can move forward from above the platform assembly to above the hydraulic flap without reversing, so that the truck can get on the hydraulic flap more quickly. When the drive device drives the platform assembly to move toward the open position, the platform assembly rotates toward the inside of the discharge pit. During this process, the downward-turned platform assembly does not have the risk of colliding with the rear end of the truck. Therefore, the hydraulic flap can turn the truck over and dump the cargo without waiting for the platform assembly to move to the open position, thereby improving the unloading efficiency. On the other hand, the downward-turned open platform assembly will not interfere with other components above the discharge pit, such as the dust removal pipe, thereby making the setting position of the discharge pit more flexible.

[0045] In one embodiment of the present invention, the discharge port platform 100 includes:

[0046] a platform assembly 110, one end of the platform assembly 110 being rotatably connected to the periphery of the discharge port; and

[0047] The driving device 120 is provided at the periphery of the discharge port, and drives the connecting platform assembly 110 to rotate the platform assembly 110 so that the platform assembly 110 has a closed position for sealing the discharge port and an open position for entering the discharge pit.

[0048] The unloading port platform 100 in the technical solution of the present invention includes a platform assembly 110 and a driving device 120. The platform assembly 110 is rotatably connected to the periphery of the unloading port. The driving device 120 drives the connected platform assembly 110 to rotate the platform assembly 110. The platform assembly 110 has a closed position and an open position through rotation. When the platform assembly 110 is in the closed position, the unloading port is closed. The truck 300 can move forward from above the platform assembly 110 to above the hydraulic flip plate 200. The truck 300 does not need to reverse, so that the truck 300 can get on the hydraulic flip plate 200 faster; when the driving device 120 drives the platform assembly 110 to move toward the open position, the platform assembly 110 rotates toward the inside of the unloading pit. During this process, the downward-flipped platform assembly 110 does not have the risk of colliding with the rear end of the truck 300. Therefore, the hydraulic flip plate 200 can flip the truck 300 to dump the goods without waiting for the platform assembly 110 to move to the open position, thereby improving the unloading efficiency. On the other hand, the platform assembly 110 that is flipped open downward will not interfere with other components above the unloading pit, such as the dust removal pipe, etc., thereby making the setting position of the unloading pit more flexible.

[0049] In this embodiment, when the platform assembly 110 is in the closed position, the upper surface of the platform assembly 110 is flush with the ground. The driving device 120 can be implemented in a rotary drive form such as a motor or a reducer, or in a linear drive form such as a hydraulic cylinder or an electric push rod.

[0050] In one embodiment, the driving device 120 includes:

[0051] A base assembly 121 is fixed to the periphery of the discharge port; and

[0052] The telescopic assembly 122 has a first end and a second end opposite to each other. The first end is rotatably connected to the base assembly 121, and the second end is rotatably connected to the platform assembly 110. The telescopic assembly 122 is telescoped to switch the platform assembly 110 between a closed position and an open position.

[0053] Combine Figure 2 and Figure 5In an embodiment of the present invention, the drive device 120 includes a base assembly 121 and a telescopic assembly 122. The base assembly 121 is used to mount the telescopic assembly 122. The ends of the telescopic assembly 122 are rotatably connected to the base assembly 121 and the platform assembly 110, respectively. This allows the telescopic assembly 122 to rotate while linearly extending and retracting, thereby driving the platform assembly 110 to rotate and preventing the telescopic assembly 122 from becoming stuck. Specifically, when the telescopic assembly 122 extends, it drives the platform assembly 110 to rotate toward the closed position; when the telescopic assembly 122 retracts, it drives the platform assembly 110 to rotate toward the open position. The telescopic movement of the telescopic assembly 122 controls the rotation of the platform assembly 110, resulting in a simple structure, easy implementation, and convenient maintenance, reducing maintenance costs during long-term use. Furthermore, the telescopic assembly 122 occupies a small space, which reduces the space occupied by the drive device 120. This reduces the possibility of collision between the truck 300 and the drive device 120 and further increases the flexibility of the unloading pit location.

[0054] In one embodiment, the telescoping assembly 122 is a hydraulic cylinder.

[0055] In an embodiment of the present invention, the telescopic component 122 is a hydraulic cylinder, which can provide a large push-pull force, thereby improving the stability and reliability of the unloading port platform 100, and especially can more effectively ensure that the truck 300 passes through the platform component 110; on the other hand, the hydraulic cylinder has a simple and sturdy structure, can maintain stable performance in harsh working environments, has a long service life, and is suitable for application in truck 300 unloading scenarios.

[0056] In one embodiment, the discharge port platform 100 further includes a first limit switch 130, which is disposed on one side of the telescopic assembly 122 and electrically connected to the telescopic assembly 122, and is used to control the working state of the telescopic assembly 122 to keep the platform assembly 110 in a closed position.

[0057] Reference Figure 5In an embodiment of the present invention, a first limit switch 130 is disposed on one side of the telescopic assembly 122 and is electrically connected to the telescopic assembly 122. Since the telescopic assembly 122 itself moves as it drives the platform assembly 110 to rotate, the position of the platform assembly 110 can be detected by detecting the position of the telescopic assembly 122. When the platform assembly 110 reaches the closed position, the telescopic assembly 122 triggers the first limit switch 130, which stops the telescopic assembly 122 from extending further, ensuring that the platform assembly 110 remains accurately in the closed position. The first limit switch 130 can be in various forms, such as a travel switch or a photoelectric switch. The first limit switch 130 can ensure that the platform assembly 110 stops moving when it reaches the closed position, thereby improving the reliability of the positioning of the platform assembly 110 and ensuring that the platform assembly 110 is flush with the ground; on the other hand, it can prevent the platform assembly 110 from being damaged due to excessive extension of the telescopic assembly 122; on the other hand, there is no need for the operator to judge whether the platform assembly 110 has reached the closed position, so that the closing of the discharge port platform 100 can be automated, reducing manual intervention and improving work efficiency.

[0058] In one embodiment, the discharge port platform 100 further includes a second limit switch 140, which is disposed on one side of the platform assembly 110 and electrically connected to the telescopic assembly 122, for controlling the working state of the telescopic assembly 122 to keep the platform assembly 110 in an open position.

[0059] Reference Figure 1 and Figure 3 In an embodiment of the present invention, a second limit switch 140 is disposed on one side of the platform assembly 110 and is electrically connected to the telescopic assembly 122. The second limit switch 140 is used to detect the position of the platform assembly 110. When the platform assembly 110 reaches the open position, the platform assembly 110 triggers the second limit switch 140, which controls the telescopic assembly 122 to stop further retraction, ensuring that the platform assembly 110 can accurately maintain the open position. The second limit switch 140 can be in various forms, such as a travel switch or a photoelectric switch. The second limit switch 140 can ensure that the platform assembly 110 stops moving when it reaches the open position, thereby improving the reliability of the positioning of the platform assembly 110 and ensuring that the discharge port is sufficiently open, thereby improving the efficiency of the goods falling into the discharge pit; on the other hand, it can prevent the platform assembly 110 from being damaged due to excessive retraction of the telescopic assembly 122, thereby extending the service life of the discharge port platform 100; on another hand, there is no need for the operator to judge whether the platform assembly 110 has reached the open position, so that the opening of the discharge port platform 100 can be automated, reducing manual intervention and improving work efficiency.

[0060] In one embodiment, the second limit switch 140 is disposed inside the unloading pit.

[0061] Reference Figure 3 In an embodiment of the present invention, the second limit switch 140 is arranged inside the unloading pit, that is, below the platform assembly 110, which can prevent people or vehicles on the platform assembly 110 from accidentally hitting or triggering the second limit switch 140, thereby improving the accuracy of the platform assembly 110 moving to the open position and extending the service life of the second limit switch 140.

[0062] In an embodiment of the present utility model, the discharge port platform 100 also includes a hydraulic station and an electrical control cabinet. The hydraulic station provides power for the hydraulic flap 200 and the telescopic assembly 122 at the same time. The electrical control cabinet is electrically connected to the drive device 120, the first limit switch 130 and the second limit switch 140, and is used to receive signals from the first limit switch 130 and the second switch and control the telescopic assembly 122 to extend and retract.

[0063] In one embodiment, the platform component 110 includes:

[0064] A grid platform 111, one end of which is rotatably connected to the periphery of the discharge port; and

[0065] The support frame 112 is disposed on a side of the grid platform 111 away from the discharge pit, and the second end of the telescopic assembly 122 is rotatably connected to an end of the support frame 112 away from the grid platform 111 .

[0066] Reference Figures 5 to 7 In an embodiment of the present invention, the platform assembly 110 includes a grille platform 111 and a support frame 112. The grille platform 111 has a plurality of grille holes, so that small-volume cargo can directly pass through the grille platform 111 into the interior of the unloading pit, further improving the unloading efficiency. In addition, the grille platform 111 is light in weight and easy to assemble; the support frame 112 is triangular in shape and is arranged on the side of the grille platform 111 away from the unloading pit, which is convenient for connection with the telescopic assembly 122 and also improves the stability of the platform assembly 110.

[0067] In one embodiment, a support frame 112 is provided on two opposite sides of the grid platform 111 , and each support frame 112 is correspondingly provided with a telescopic assembly 122 . The two telescopic assemblies 122 are synchronously telescoped.

[0068] Reference Figures 6 and 7In an embodiment of the present invention, a support frame 112 is provided on each side of the width direction of the grille platform 111, and a driving device 120 is correspondingly provided for each support frame 112. The two driving devices 120 synchronously drive the two sides of the width direction of the grille platform 111, providing more supporting force for the grille platform 111 and making the force on the grille platform 111 more uniform, thereby further improving the stability and safety of the grille platform 111.

[0069] In one embodiment, the base assembly 121 includes:

[0070] A seat body 1211 is provided at the periphery of the discharge port, and one end of the telescopic assembly 122 is rotatably connected to the seat body 1211; and

[0071] The embedded part 1212 is connected to the base body 1211 and fixed in the concrete foundation around the unloading pit.

[0072] Reference Figures 5 and 6 In an embodiment of the present utility model, the base assembly 121 includes a base body 1211 and an embedded part 1212. The embedded part 1212 is fixed in the concrete foundation, and the base body 1211 is welded to the embedded part 1212, which greatly improves the stability of the base assembly 121, thereby improving the stability of the telescopic assembly 122 during the telescopic process.

[0073] In one embodiment, one end of the embedded component 1212 away from the base 1211 is bent to form an anchoring structure 12121 .

[0074] Reference Figure 5 In an embodiment of the present invention, one end of the embedded part 1212 away from the base body 1211 is bent to form an anchoring structure 12121. The anchoring structure 12121 can be L-shaped, hook-shaped, wavy or multi-bend, etc., to increase the bonding force between the embedded part 1212 and the concrete, thereby making the base assembly 121 more stable. Especially when the base assembly 121 is subjected to an upward pull force, the anchoring structure 12121 can provide additional pull-out resistance to prevent the base body 1211 from moving upward due to external force.

[0075] Specifically, the specific unloading process of the discharge port platform 100 is as follows: in the initial state, the discharge port platform 100 is in the closed position, the hydraulic cylinder is in the extended state, at this time the first limit switch 130 is in the triggered state, the truck 300 passes through the platform assembly 110 and enters the hydraulic flap 200, the wheel stopper of the hydraulic flap 200 rises, and then the hydraulic cylinder of the discharge port platform 100 retracts, and the platform assembly 110 rotates downward until the second limit switch 140 is in the triggered state. After the first limit switch 130 is disconnected, The flip platform of the hydraulic flip plate 200 can drive the truck 300 to start flipping, so that the truck 300 enters the unloading state. After the material flows smoothly into the unloading pit and the unloading is completed, the hydraulic flip plate 200 drives the truck 300 to descend and return to a horizontal state. The hydraulic cylinder of the unloading port platform 100 extends, causing the platform assembly 110 to rotate upward until the first limit switch 130 is triggered again, so that the platform assembly 110 returns to the closed position, the wheel stopper retracts, and the truck 300 drives out of the hydraulic flip plate 200 in the forward direction, and the entire unloading process is completed.
