The electro-hydraulic station is fixed to the side of the trolley's balance beam connecting frame, precisely controlling the hydraulic cylinder stroke via a limit switch, and connects to a controller with a wireless module for remote operation. This structure replaces manual climbing operations, eliminates eccentric load torque through simultaneous double-sided anchoring, and enhances self-locking reliability with a wedge-shaped contact surface, achieving efficient, safe, and stable automated anchoring operations.

Description

Technical Field

[0001] This utility model relates to the technical field of bulk cargo loading and unloading machinery and equipment in the rear storage yard of a wharf, and in particular to an electric hydraulic anchoring device for a bucket wheel excavator. Background Technology

[0002] With the development of bulk cargo handling machinery and equipment technology in port backyards, the bucket wheel stacker-reclaimer has emerged as a core handling equipment. This technology features strong continuous operation capability and high stacking and reclaiming efficiency, effectively meeting the large-scale needs of port bulk cargo transshipment, and thus becoming a key piece of equipment in modern port backyards.

[0003] In related technologies, the anchoring operation of bucket wheel stacker-reclaimers is usually carried out manually, requiring workers to manually control the anchoring device to secure the equipment. The specific process includes: before operation, workers need to climb to the anchoring position of the equipment and manually insert or remove the anchoring pins; during operation, the equipment status needs to be monitored in real time and the anchoring force needs to be adjusted; after operation, the reverse operation needs to be repeated to release the anchor.

[0004] However, the above-mentioned manual anchoring method has significant problems:

[0005] First, each manual anchoring operation takes a long time, which affects the efficiency of equipment operation.

[0006] Second, manual operation makes it difficult to ensure the consistency of anchoring torque, and equipment slippage accidents are prone to occur under severe working conditions such as strong winds.

[0007] Third, the high intensity of physical labor can easily lead to worker fatigue, further exacerbating safety hazards. Utility Model Content

[0008] In response to the shortcomings of the existing production technology, the applicant provides an electric hydraulic anchoring device for the main trolley of a bucket wheel excavator, thereby enabling electric operation, reducing manual intervention, and lowering labor intensity.

[0009] The technical solution adopted in this utility model is as follows:

[0010] An electro-hydraulic anchoring device for a bucket wheel excavator includes:

[0011] The components include a pin plate, an anchor seat fixed to the ground, a hydraulic cylinder that drives the pin plate, an electric hydraulic station that provides power to the hydraulic cylinder, a trolley balance beam connecting frame installed on the trolley frame, and a limit switch that controls the stroke of the hydraulic cylinder.

[0012] The bottom of the hydraulic cylinder is connected to the pin plate via a hinge shaft, and the top of the hydraulic cylinder is hinged to the trolley balance beam connecting frame via a hinge shaft.

[0013] The hydraulic cylinder is connected to the electric hydraulic station via an oil circuit, and the electric hydraulic station is fixedly installed on the side of the support of the trolley balance beam connecting frame.

[0014] As a further improvement to the above technical solution:

[0015] In one embodiment, the bottom hinge point of the hydraulic cylinder is connected to the upper end of the pin plate, forming a vertically downward driving force transmission path.

[0016] In one embodiment, the anchor seat has a symmetrically distributed guide rail structure, with each side guide rail being matched and plugged into a pin plate.

[0017] In one embodiment, the large frame is provided with symmetrical through-hole structures on both sides, and two pin plates are respectively movably inserted into the corresponding through holes to form a double-sided synchronous anchoring mechanism.

[0018] In one embodiment, the limit switch is located at the end of the movement path of the pin plate to detect whether the pin plate is fully inserted or disengaged.

[0019] In one embodiment, the electro-hydraulic station is connected to a controller, which is configured with a wireless communication module and connected to a remote controller.

[0020] In one embodiment, the controller automatically cuts off the power supply to the hydraulic cylinder based on the feedback signal from the limit switch.

[0021] In one embodiment, an installation platform is added to one side of the trolley balance beam connecting frame, and the electric hydraulic station is fixed to the installation platform by bolts.

[0022] In one embodiment, the hydraulic cylinder, the electric hydraulic station, and the limit switch constitute a closed hydraulic control system to achieve automatic maintenance and release of the anchoring force.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model has a compact structure. Through the symmetrical guide rails on both sides of the anchor seat and the through holes on both sides of the main frame, the two pin plates are arranged on the left and right. Driven synchronously by the hydraulic cylinder, the pins on both sides are inserted into the anchor seat at the same time, avoiding the distortion of the main frame caused by unilateral force. The symmetrical force distribution improves the anchoring force. In addition, the bottom of the hydraulic cylinder is hinged to the upper part of the pin plate to form a vertical downward thrust, and the top of the hydraulic cylinder is hinged to the main frame balance beam connecting frame to form a fixed force application fulcrum. The vertical force application makes the contact surface pressure between the pin plate and the anchor seat uniform. Attached Figure Description

[0034] like Figures 1-2 The accompanying drawing shows a structural schematic diagram of an electro-hydraulic anchoring device for a bucket wheel excavator according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0035] This utility model provides an electric hydraulic anchoring device for a bucket wheel excavator, including a pin plate 100, an anchoring seat 200, a hydraulic cylinder 300, an electric hydraulic station 400, a trolley balance beam connecting frame 500, and a limit switch 600.

[0036] In some embodiments, the anchoring seat 200 is vertically fixed to the ground foundation by anchor bolts, and its top is provided with symmetrically distributed guide rail structures, the spacing of which matches the wheel track of the main frame.

[0037] In some embodiments, the main trolley balance beam connecting frame 500 is welded to the center position of the bottom of the bucket wheel excavator frame, and an installation platform extends from one side of it, with an array of bolt mounting holes machined on the surface of the platform.

[0038] In some embodiments, the electric hydraulic station 400 is fixed to the side of the mounting platform by high-strength bolts, and its output end is connected to the oil inlet and oil return port of the hydraulic cylinder 300 through a high-pressure oil pipe.

[0039] In some embodiments, the top hinge point of the hydraulic cylinder 300 is hinged to the ear plate of the trolley balance beam connecting frame 500 through a pin assembly to form a fixed rotation fulcrum; the bottom hinge point is connected to the upper end of the pin plate 100 through a universal joint hinge shaft, so that the extension and retraction motion of the hydraulic cylinder 300 is converted into a vertically downward linear driving force.

[0040] In some embodiments, the lower end of the pin plate 100 is matched and inserted into the guide rail of the anchor seat 200, and the middle part passes through the through hole of the side wall of the frame.

[0041] In some embodiments, two pin plates 100 are symmetrically distributed on the left and right sides of the main frame. The left pin plate 100 is connected to the bottom of the left hydraulic cylinder 300 through a hinge, and the right pin plate 100 is connected to the right hydraulic cylinder 300. When the hydraulic cylinders 300 extend synchronously, the two pin plates 100 descend vertically along the through hole of the main frame until the slot is engaged with the guide rail of the anchor seat 200, forming a double-sided mechanical lock.

[0042] In some embodiments, the limit switch 600 is mounted on the inner side wall of the guide rail of the anchor seat 200, with the detection end aligned with the boss at the lower end of the pin plate 100.

[0043] In some embodiments, the controller is integrated into the electro-hydraulic station 400 and receives the position signal from the limit switch 600; at the same time, the controller establishes a connection with the remote controller through the wireless communication module; after the trigger signal is triggered, the power supply to the hydraulic pump is immediately cut off and the hydraulic lock-up valve is activated to maintain pressure.

[0044] In practice, the workflow of this utility model is as follows:

[0045] Anchoring command: The remote controller sends a start signal → the controller starts the electric hydraulic station 400 → the hydraulic cylinder 300 extends synchronously;

[0046] Mechanical locking: The pin plate 100 is vertically inserted into the anchor seat 200 guide rail → the limit switch 600 detects the position → the system enters the pressure holding state;

[0047] Release anchoring: Remote release command → Hydraulic cylinder 300 retracts → Pin plate 100 is raised to disengage from the guide rail → Limit switch 600 resets.

[0048] In summary, this utility model uses symmetrical guide rails on both sides of the anchor seat 200 and through holes on both sides of the main frame to separate the two pin plates 100 to the left and right. Driven synchronously by the hydraulic cylinder 300, the pin plates 100 on both sides are inserted into the anchor seat 200 at the same time, avoiding the distortion of the main frame caused by unilateral force. The symmetrical force distribution improves the anchoring force.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
