Description
TECHNICAL FIELD
[0001] The utility model relates to the port automation equipment technical field field, specifically disclose the alignment check device of automatic track crane one key anchoring system. BACKGROUND
[0002] The anchoring system accurate alignment device of automatic track crane is through integrated high accuracy sensor and dynamic adjusting mechanism, solves the alignment deviation problem of anchoring plate and anchoring pit caused by factors such as wharf site settlement, trolley deviation, especially suitable for the anchoring operation scene of double-suspension automatic track crane, suspensionless track crane and other equipment.
[0003] In the automatic wharf yard, the '' one key anchoring system '' of track crane has replaced manual operation, but there are still significant defects in its actual application:
[0004] 1. The positioning accuracy is insufficient: the traditional scheme relies on encoder and Flag calibration, but track settlement, wheel skidding and other reasons can cause trolley deviation or encoder data misalignment, and the horizontal deviation of anchoring plate and anchoring pit can reach more than 100mm, and the anchoring failure rate is as high as 35%;
[0005] 2. Serious mechanical loss: if the anchoring plate and the anchoring pit are not aligned, the anchoring motor instantaneous current overload when forcibly anchoring, and the push rod is easy to deform under lateral impact, and the annual average maintenance cost of a single device increases by 40-50 thousand yuan;
[0006] 3. Safety hazards are prominent: in extreme weather (such as typhoon, heavy rain), maintenance personnel need to frequently enter the yard to adjust the anchoring plate, and there is a risk of slipping, electric shock and other risks;
[0007] 4. Poor adaptability: the existing fixed calibration device cannot dynamically compensate for site settlement (annual settlement is about 1-3mm), resulting in alignment failure after long-term use.
[0008] In the prior art, some schemes try to improve the positioning accuracy by encrypting Flag plate or optimizing encoder algorithm, but there are the following limitations:
[0009] 1. There is still a certain blind area between the two Flag plates, which cannot achieve absolute positioning;
[0010] 2. Algorithm optimization cannot solve the mechanical deviation problem at the physical layer.
[0011] Therefore, a device with accurate measurement, dynamic adjustment and active protection is needed to improve the reliability and safety of the anchoring system. UTILITY MODEL CONTENTS
[0012] Therefore, the purpose of the utility model is to provide an alignment check device for the one key anchoring system of automatic track crane to solve the technical problem of how to accurately position and align the anchoring plate and the anchoring pit.
[0013] To achieve the above object, the utility model provides the following technical scheme:
[0014] An automatic rail-mounted crane one-key anchoring system alignment verification device, including inductive proximity sensor arranged on the anchoring plate and calibrator arranged on the anchoring pit;The calibrator includes a base, a screw rod adjusting mechanism and a calibration plate, the screw rod adjusting mechanism is arranged on the base, the calibration plate is arranged on the screw rod adjusting mechanism, and the screw rod adjusting mechanism can adjust the height of the calibration plate.In the scheme, positioning is mainly carried out through the principle that the inductive proximity sensor can send signals when approaching metal, when the distance between the inductive proximity sensor and the calibration plate reaches the standard (less than or equal to 5cm), it indicates that the inductive proximity sensor reaches the target position, that is, the anchoring plate and the anchoring pit position are aligned, at this time, anchoring can be carried out.The screw rod adjusting mechanism is arranged on the calibration plate, and the screw rod adjusting mechanism can vertically adjust the position of the calibration plate.
[0015] Optionally, the anchoring plate is provided with a position adjusting mechanism, and the inductive proximity sensor is arranged on the position adjusting mechanism, and the position adjusting mechanism can adjust the position of the inductive proximity sensor in the horizontal and vertical directions.The position adjusting mechanism can adjust the position of the inductive proximity sensor to correct the displacement of the inductive proximity sensor caused by typhoon and the like.
[0016] Optionally, the top of the screw rod adjusting mechanism is provided with a spherical hinge, the calibration plate is arranged on the spherical hinge, the bottom of the calibration plate is provided with a detachable support, the support is arranged on the ground, and the support is perpendicular to the ground.In the scheme, the support is vertically arranged on the ground, and the support is fixedly connected with the calibration plate, so that the calibration plate is perpendicular to the ground;When the ground subsides, deforms or the like, the support can be detached, and then the length of the support is replaced to keep the calibration plate in a horizontal state.
[0017] Optionally, the position adjusting mechanism includes a horizontal screw rod, the horizontal screw rod is arranged on the anchoring plate, a horizontal sliding seat is arranged on the horizontal screw rod, a vertical screw rod is threadedly connected to the bottom of the horizontal sliding seat, an installation plate is arranged at the bottom of the vertical screw rod, and the inductive proximity sensor is arranged on the installation plate.By adopting the scheme, the horizontal position of the horizontal sliding seat can be adjusted by the horizontal screw rod mechanism, and then the horizontal position of the inductive proximity sensor can be adjusted.The vertical position of the inductive proximity sensor can be adjusted by the vertical screw rod.
[0018] Optionally, the inductive proximity sensor is vertically arranged on the installation plate in a threaded connection mode.The connection mode of the scheme is simple and convenient.
[0019] Optionally, a waterproof sleeve is sleeved on the inductive proximity sensor.
[0020] The working principle and beneficial effects of this solution are as follows:
[0021] In this design, an inductive proximity sensor is installed on the anchoring plate, and a metal calibration plate is placed next to the anchoring pit. When the inductive proximity sensor approaches the calibration plate, it detects the calibration plate and sends a signal, indicating that the inductive proximity sensor and the calibration plate are close enough. This further confirms that the anchoring plate and the anchoring pit are aligned, allowing for anchoring. The design includes horizontal and vertical screws to adjust the horizontal and vertical positions of the inductive proximity sensor, preventing it from shifting over time. A screw adjustment mechanism is also located at the bottom of the calibration plate to adjust its height, and a bracket is used to adjust the levelness of the calibration plate.
[0022] The structure in this solution is very simple. The horizontal screw, vertical screw, and screw adjustment mechanism used are all very common structures.

Detailed Implementation
[0027] The following detailed description illustrates the specific implementation method:
[0028] Example 1
[0029] An alignment and verification device for an automated rail-mounted crane one-button anchoring system, such as Figure 1 As shown, it includes an inductive proximity sensor 7 mounted on the anchor plate and a calibrator mounted on the anchor pit 1.
[0030] An anchor plate is equipped with a position adjustment mechanism, on which an inductive proximity sensor 7 is mounted. The position adjustment mechanism can adjust the position of the inductive proximity sensor 7 in both horizontal and vertical directions. The position adjustment mechanism includes a horizontal screw 2, which is horizontally fixed to the anchor plate. A horizontal slide block 4 is slidably mounted on the horizontal screw 2. Two nuts 3 are installed on the horizontal screw 2, located at the front and rear ends of the horizontal slide block 4 respectively. A vertical screw 5 is threadedly connected to the bottom of the horizontal slide block 4. A mounting plate 6 is fixedly mounted to the bottom of the vertical screw 5. The inductive proximity sensor 7 is mounted on the mounting plate 6 via a threaded connection. A waterproof sleeve is fitted over the inductive proximity sensor 7.
[0031] The calibrator includes a base 8, a screw adjustment mechanism 9, and a calibration plate 10. The base 8 is fixedly set on the ground next to the anchoring pit 1, the screw adjustment mechanism 9 is set on the base 8, and the calibration plate 10 is fixedly set on the screw adjustment mechanism 9.
[0032] In practice:
[0033] First, the position of the inductive proximity sensor 7 is adjusted using the position adjustment mechanism. Simultaneously, a calibrator is installed next to the anchoring pit 1, and the position of the calibration plate 10 is adjusted. When the rail-mounted gantry crane reaches the preset position in the anchoring pit 1, the onboard sensors begin detecting the alignment device. If the lateral distance error is ≤5CM, it is determined that "anchoring is permitted." The vehicle anchoring mechanism is activated, and the anchoring motor drives the anchoring plate into the anchoring pit 1 via a worm gear, completing the anchoring. If the lateral distance error is >5CM, the onboard sensors cannot detect the ground-based alignment device, the system will alarm and trip, requesting manual intervention from the remote control operator.
[0034] Example 2
[0035] An alignment and verification device for an automated rail-mounted crane one-button anchoring system, such as Figure 2 As shown, it includes an inductive proximity sensor 7 mounted on the anchor plate and a calibrator mounted on the anchor pit 1.
[0036] An anchor plate is equipped with a position adjustment mechanism, on which an inductive proximity sensor 7 is mounted. The position adjustment mechanism can adjust the position of the inductive proximity sensor 7 in both horizontal and vertical directions. The position adjustment mechanism includes a horizontal screw 2, which is horizontally fixed to the anchor plate. A horizontal slide block 4 is slidably mounted on the horizontal screw 2. Two nuts 3 are installed on the horizontal screw 2, located at the front and rear ends of the horizontal slide block 4 respectively. A vertical screw 5 is threadedly connected to the bottom of the horizontal slide block 4. A mounting plate 6 is fixedly mounted to the bottom of the vertical screw 5. The inductive proximity sensor 7 is mounted on the mounting plate 6 via a threaded connection. A waterproof sleeve is fitted over the inductive proximity sensor 7.
[0037] The calibrator includes a base 8, a screw adjustment mechanism 9, and a calibration plate 10. The base 8 is fixedly mounted on the ground next to the anchoring pit 1. The screw adjustment mechanism 9 is mounted on the base 8, and a ball joint 13 is provided on the top of the screw adjustment mechanism 9. The calibration plate 10 is fixedly mounted on the ball joint 13. The screw adjustment mechanism 9 can adjust the height of the calibration plate 10. A bracket 11 is detachably mounted on the bottom surface of the calibration plate 10 via a hanging ring 12. A hanging ring 12 is also provided on the ground, and the bracket 11 is mounted on the ground via the hanging ring 12.
[0038] In practice:
[0039] The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 adds a ball joint and bracket 11 structure. After the calibration plate 10 is installed on the ball joint, the calibration plate 10 is in a movable state. The bracket 11 connects the calibration plate 10 to the ground. As long as the length of the bracket 11 is sufficient, the calibration plate 10 can be kept in a horizontal state. This structure is mainly used for ground with severe settlement and deformation, such as ground with severe torsion that causes the calibration plate 10 to deflect significantly. In this case, the bracket 11 can be disassembled and a new bracket 11 of appropriate length can be made and installed to keep the calibration plate 10 in a horizontal state under the support of the bracket 11.
[0040] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
