[0026] The anchor assembly 5 is rotatably connected to the driver's cab 3, and the front end of the anchor assembly 5 is used to slide into the anchor groove 63 through the anchoring slideway 61;

[0027] The lifting assembly 4 is arranged above the anchoring assembly 5, and the lifting assembly 4 is used to drive the front end of the anchoring assembly 5 to lift up or drop down.

[0028] In this embodiment, the anchor assembly 5 includes a fixed bracket and an anchor plate 54. The fixed bracket includes a fixed bottom plate 51 and two fixed ears 52. The fixed bottom plate 51 is fixed on the driver's cab 3 walkway pedal grille near the anchoring position of the driver's cab 3. The two fixed ears 52 are fixed on the fixed bottom plate 51 at intervals. A rotating rod 53 is rotatably connected between the two fixed ears 52. The rear end of the anchor plate 54 is fixed to the rotating rod 53, so as to be rotatably connected to the fixed bracket, and the front end of the anchor plate 54 is engaged with the anchor groove 63. The fixed bracket is fixed to the driver's cab 3 to provide rotation support for the anchor plate 54. The front end of the anchor plate 54 is used to engage with the anchor groove 63 to anchor the driver's cab 3.

[0029] In this embodiment, an unanchoring switch 55 and an anchoring switch 56 are respectively fixed on the two fixing ears 52 of the fixing bracket. The unanchoring switch 55 and the anchoring switch 56 are proximity switches. When the front end of the anchoring assembly 5 is lifted, it is close to the unanchoring switch 55, and when the front end of the anchoring assembly 5 is dropped, it is close to the anchoring switch 56. The unanchoring switch 55 and the anchoring switch 56 are both connected to the control system of the driver's cab 3. Through the unanchoring switch 55 and the anchoring switch 56, a signal is sent to the control system, so as to determine the unanchoring and anchoring states, so as to facilitate the control system to control the lifting assembly 4 to rise and fall.

[0030] In this embodiment, the lifting assembly 4 includes an electric push rod 41 and a connecting chain 42. The electric push rod 41 is connected to the control system of the driver's cab 3. The housing of the electric push rod 41 is fixed on the walkway guardrail of the driver's cab 3. The output end of the electric push rod 41 is connected to the connecting chain 42. The lower end of the connecting chain 42 is connected to the front end of the anchor plate 54 through a connecting lug. Preferably, the upper end and the lower end of the connecting chain 42 are respectively connected to the output end of the electric push rod 41 and the front end of the anchor plate 54 by a snap connection, which is convenient for disassembly and assembly and addition and subtraction of the connecting chain 42, so that the device can be applied to a variety of ship unloaders. The anchor plate 54 is lifted and lowered by the electric push rod 41 and the connecting chain 42 to realize automatic anchoring and automatic unanchoring of the driver's cab 3.

[0031] In this embodiment, a fixed block is fixed on the top of the cab 3, and an anchor release lever 2 is rotatably connected to the side wall of the fixed block. The top of the anchor release lever 2 extends upward, and an anchor release limit 1 is fixedly arranged on the ship unloader cross beam above the cab 3. When the cab 3 leaves the anchoring position, the top of the anchor release lever 2 contacts the anchor release limit 1, so that the anchor release lever 2 swings. A sensor capable of detecting the position change of the top of the anchor release lever 2 is arranged on the anchor release lever 2. The anchor release lever 2 is connected to the control system of the cab 3, so as to send an anchor release signal to the control system of the cab 3. The anchor release lever 2 provides an anchor release signal to the control system of the cab 3, so that the control system can control the lifting assembly 4 to lower the anchor plate 54, so that the anchor plate 54 is flat, so that when the cab 3 returns to the anchoring position, the anchor plate 54 can automatically slide into the anchor groove 63 through the anchoring slide 61.

[0032] In this embodiment, a fixing slot 541 is provided at the front end of the anchor plate 54, and a clamping block 62 smaller than the size of the fixing slot 541 is fixed to one side of the anchoring slot 63 of the anchor plate 54. When the anchor plate 54 slides into the anchoring slot 63, the clamping block 62 automatically inserts into the fixing slot 541. The clamping block 62 cooperates with the fixing slot 541 to prevent the driver's cab 3 from slightly moving laterally and driving the anchor plate 54 to move, so that the anchor plate 54 falls off from the anchoring slot 63, affecting the anchoring effect of the driver's cab 3.

[0033] When anchoring is performed by the device of this embodiment:

[0034] During the process of the driver's cab 3 returning to the anchoring position, the front end of the anchoring plate 54 first contacts the anchoring slide 61 of the limit plate 6, and driven by the driver's cab 3, slides into the anchoring groove 63 through the anchoring slide 61. When the anchoring plate 54 slides into the anchoring groove 63 and approaches the anchoring switch 56 on the fixed bracket, the control system receives the signal of the anchoring switch 56 and can determine that the driver's cab 3 is anchored, thereby controlling the driver's cab 3 to stop moving.

[0035] When unmooring by the device of this embodiment:

[0036] The control system of the driver's cab 3 controls the electric push rod 41 to retract, and the front end of the anchor plate 54 is lifted from the anchor groove 63 under the drive of the connecting chain 42. At this time, the driver's cab 3 has been unanchored, and then the driver's cab 3 can be controlled to move; when the driver's cab 3 moves below the anchoring limit 1, the anchoring lever 2 at the top of the driver's cab 3 contacts the anchoring limit 1 and rotates, so that the anchoring lever 2 sends an anchoring signal to the driver's cab 3 control system, and the driver's cab 3 control system controls the electric push rod 41 to extend through the anchoring signal. At this time, the front end of the anchor plate 54 is flattened so that the driver's cab 3 returns to the anchoring position and slides into the anchoring groove 63.

[0037] The automatic anchoring device of the utility model can realize automatic anchoring and automatic unanchoring of the driver's cab 3, avoiding the danger of the operator anchoring outside the driver's cab 3; through this device, when the driver's cab 3 returns to the anchoring position, the front end of the anchor plate 54 automatically slides into the anchoring groove 63 through the anchoring slide 61, and the driver's cab 3 is automatically anchored; when the driver's cab 3 needs to leave the anchoring position, the front end of the anchoring assembly 5 is lifted by the lifting assembly 4, so that the anchor plate 54 and the anchoring groove 63 are unanchored, thus ensuring that the driver's cab 3 will not slide accidentally and the safety of the operator is also guaranteed.
