Description

Technical Field

[0001] The utility model relates to the technical field of port lifting equipment and detection accessories thereof, and in particular to a FLAG plate positioning and installation device used for positioning an automated rail crane trolley. Background Art

[0002] The trolley positioning solution for automated rail cranes usually uses a laser sensor + FLAG board + incremental encoder calibration method. This solution is characterized by high precision and low cost, and is widely used in domestic docks. However, the design of the FLAG board is different. In the prior art, if an L-shaped FLAG board is used and fixed with expansion bolts, there are two problems during use: 1. Due to the settlement of a local area of ​​the yard, the FLAG board in some positions cannot be sensed, resulting in abnormal positioning of the rail crane trolley; 2. Due to the loose installation of the expansion bolts, the FLAG board tilts forward and backward, causing interference between the FLAG board and the laser sensor mounting bracket, resulting in damage to the FLAG board.

[0003] Other adjustment schemes for the FLAG board are mainly to achieve the design purpose by changing the positioning device for installing the FLAG board. For example, the Chinese utility model patent "An automated rail crane trolley positioning device with a flag board" with application number 202223002566.7 chooses a segmented design: the FLAG board is divided into three sections, the FLAG board, the middle connecting plate and the L-shaped bracket connected from top to bottom relative to the ground. The mounting hole of the middle connecting plate is designed to be a long hole to facilitate limited height adjustment of the FLAG board. Although the technical solution of this utility model solves the problem of height adjustment of the FLAG board, the size of its connecting plate limits the adjustable height. If a higher height needs to be adjusted, a connecting plate needs to be added or remade. Moreover, this design form is difficult to adapt to problems such as settlement of port yards. If rectification is required in the later stage, sufficient FLAG boards need to be processed in advance for backup. If all of them are replaced, the construction will be more complicated.

[0004] The automated rail crane detects the FLAG board installed on the ground through the laser sensor on the inside of the trolley mechanism and realizes the precise positioning of the trolley mechanism by combining the comprehensive verification of the trolley encoder. However, due to the settlement of the installation position of the FLAG board, the laser sensor installed on the trolley cannot detect the FLAG board, resulting in the problem that the trolley positioning cannot be calibrated in real time. In this case, it is necessary to adjust the height of the FLAG board to reach the detection height of the rail crane laser sensor, or adjust the installation height of the laser sensor. However, the height of the FLAG board itself is fixed and cannot be adjusted or the adjustable height is limited. The height of the laser sensor is also limited due to the installation position. At the same time, because the trolley driving range of the rail crane is about 700 meters, the number of FLAG boards covered is large, and the settlement of each position is different, which makes the adjustment more difficult.

This construction process has a defect: the curing of anchoring glue requires a long time, and the on-site operation cannot be interrupted. Therefore, the normal use of FLAG board 100 needs to be ensured during the time waiting for the anchoring glue to cure; the reserved through groove 9 is convenient for adjusting the position of the fifth screw rod 12 during anchoring, so as to ensure that the installation error of FLAG board 100 is within the allowable range after the anchoring glue solidifies and the installation bracket is removed; by designing a FLAG board positioning and installation device for the automated rail crane trolley, after the screw rod is anchored, the FLAG board 100 is fixed to the screw rod through the installation device, which not only ensures the verticality of the screw rod after the screw rod is anchored, but also solves the operation requirements of the automated rail crane; after the anchoring glue is cured, the FLAG board 100 positioning and installation device can be removed and reused.

[0070] In addition, the clamping assembly can be two sets of bolts and nuts used to tightly fit the FLAG plate 100 to the front side of the vertical back plate 6; through holes are provided on the left and right sides of the vertical back plate 6 and the FLAG plate 100, and the left and right sides of the FLAG plate 100 are locked by two sets of bolts and nuts.

[0071] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
