[0025] Control motor 12 is connected with control switch circuit in button box 11, and the internal control circuit of button box 11 can control the positive and negative rotation of motor 12 by remote PLC and the button installed on button box 11 again;Control motor 12 positive and negative rotation is driven up or down of anchoring plate 10 by transmission rod 5 and lug 3.

[0026] Anchoring plate 10, the upper end of the anchoring plate 10 is connected with transmission rod 5 by lug 3, and the transmission rod 5 drives the anchoring plate 10 to rise or fall;The anchoring plate 10 is vertically through two cross plates, and the cross plates are fixed on the cart walking mechanism, and the corresponding position of the anchoring plate 10 is opened, the opening size is suitable for the anchoring plate 10 to pass through, and the two cross plates can ensure the firmness and stability of the anchoring plate 10.

[0032] The upper proximity switch is used for detecting and controlling the rising of the anchor plate 10 to the position, and the lower proximity switch is used for detecting and controlling the lowering of the anchor plate 10 to the position. When the anchor plate 10 rises or lowers to the position, the upper and lower proximity switches detect the signal of the position, and then transmit the signal to the control center. The control center judges the position of the anchor plate 10 according to the signal of the upper / lower proximity switch. That is, the rising to the position or the lowering to the position realizes the lifting and anchoring functions.

[0033] When the proximity switch fails, the anchor plate 10 continues to rise or lower, and after moving a small distance, the travel switch 7 is contacted.

[0034] In some embodiments, the distance between the first proximity switch 13, the second proximity switch 14 and the switch baffle 8 is less than 15mm.

[0035] The proximity switch and the travel switch 7 play a double safety protection role in the whole operation of the electric anchoring device, and ensure the safety of the electric anchoring device. The rising and lowering of the anchor plate 10 to the position contacts the proximity switch or the travel switch 7 and stops; the installation of the proximity switch and the travel switch 7 in the large vehicle anchoring device can ensure that when the proximity switch fails, the other travel switch 7 is effective, so that the safety accident caused by the anchoring failure of the whole equipment is avoided; the electric anchoring device is installed on the walking mechanism of the ship loader large vehicle, and the automatic disengagement and anchoring are realized.

[0036] In order to improve the overall strength, the welding base 1, the connecting base 2, the lug 3, the proximity switch support 4, the button box 11 support, the travel switch support 6 and the proximity switch baffle 8 in the assembled and processed parts are all made of carbon structural steel (Q235). During the assembly process of the whole device, all the bolts, nuts, flat washers and flat washers used are made of stainless steel, and are subjected to reinforcement and rust prevention treatment.

[0037] An anchor pit is arranged on the track side, the anchor plate 10 is lowered and inserted into the anchor pit through the transmission rod 5, and the large vehicle is anchored.

[0038] The anchor pit is surrounded by steel material, and a right trapezoidal steel material reinforcing plate is arranged in front of and behind the anchor pit in the direction of the track.

[0039] When the second proximity switch 14 detects the switch baffle 8, the position of the anchor plate 10 descending is the depth of the anchor pit.

[0040] The device further comprises a connecting base 2 and a welding base 1, the connecting base 2 is fixed on the cart walking mechanism through the welding base 1, the welding base 1 is a pair of welding bases on the cart walking mechanism, the connecting base 2 is in the shape of a convex upper half, and both ends are welded on the welding base 1 to form a base platform, the control motor 12 is fixed on the base platform, and the transmission rod 5 passes through the base platform.

[0041] In some embodiments, when strong wind weather occurs or other conditions require anchoring of the cart mechanism, the cart is controlled to travel in the direction of the anchor pit, and a limiting piece can be arranged on the track to control the parking position of the cart to be exactly in the best position for anchoring.

[0042] In some embodiments, after the cart is configured with a position detection device and an electric anchoring device, not only can the cart anchoring device be controlled by a remote or local button box 11, but also a "one-key anchoring" function can be set. The cart walking mechanism can master the walking distance in real time through an absolute value encoder and an RFID magnetic nail calibration system, and when anchoring is needed, the cart walking mechanism can be pre-walked above the anchor pit through the "one-key anchoring" function. At this time, the electric anchoring process is formally entered.

[0043] When the cart walking mechanism reaches the anchoring position, remote or manual operation buttons can be used to control the start of anchoring operation, which is realized through the internal control circuit of the button box 11, such as remote PLC function; the manual operation button is a switch arranged on the button box 11, and when anchoring operation is needed, the button can be pressed. The device realizes automatic anchoring through electricity, specifically using a control motor 12 to provide kinetic energy, the control motor 12 has forward and reverse functions, can drive the transmission rod 5 to move forward or backward, and thus realizes anchoring and disengagement of the cart. The forward and reverse rotation of the control motor 12 can be controlled by remote PLC or buttons.

[0044] Specifically, the control center is used for controlling the operation of the device, when receiving the anchoring instruction, the control motor 12 is controlled to rotate forward to drive the transmission rod 5, when the transmission rod 5 moves downward, the anchoring plate 10 gradually descends, when the travel switch 7 is triggered, the control center receives the triggering information of the travel switch 7, at this time, the control center confirms that the anchoring plate 10 has descended to the specified position, that is, the control motor 12 stops working. At the same time, the second proximity switch 14 in the device is just in line with the position of the switch baffle 8 at this time, the second proximity switch 14 can sense the distance from the switch baffle 8, so as to judge that the anchoring plate 10 has reached the specified anchoring position, and transmit the information to the control center, after the control center receives the sensing information of the second proximity switch 14, it is confirmed whether the control motor 12 stops at this time. That is, the anchoring effect is ensured by the travel switch 7 and the proximity switch.

[0045] Specifically, when the cart walking mechanism needs to be disengaged from the anchoring, the control center issues an instruction to control the control motor 12 to reverse the rotation to drive the transmission rod 5 to move upward, so that the anchoring plate 10 rises. When the anchoring plate 10 rises to a certain height, the travel switch 7 is triggered, at this time, it is judged that the anchoring plate 10 has disengaged from the anchoring pit, after the control center receives the information, the control motor 12 stops working. At the same time, the first proximity switch 13 in the device is just in line with the position of the switch baffle 8 at this time, the first proximity switch 13 can sense the distance from the switch baffle 8, so as to judge that the anchoring plate 10 has reached the specified anchoring position, and transmit the information to the control center, after the control center receives the sensing information of the first proximity switch 13, it is confirmed whether the control motor 12 stops at this time. That is, the disengaging anchoring effect is ensured by the travel switch 7 and the proximity switch.
