Description

Technical Field

[0001] The utility model relates to the technical field of automatic anchoring, in particular to an automatic anchoring device for a stacker cantilever. Background Art

[0002] As a large-scale storage and transportation equipment in ports, the cantilever frame of the stacker is directly exposed to the external environment, especially the wind, during operation. As the size and windward area of ​​the stacker increase, the threat posed by wind load to its stability is increasing. Strong winds, especially sudden gusts, have become a key factor affecting port safety production. As the main wind load-bearing component, the structural safety of the cantilever frame is directly related to the stability and operational safety of the entire stacker. Therefore, the importance of the stacker cantilever anchoring device is self-evident. It can not only ensure the stability of the cantilever frame under severe weather conditions, but also effectively prevent equipment damage and safety accidents caused by excessive wind loads. It is one of the important equipment to ensure port safety production.

[0003] The existing stacker boom anchoring device includes a steel wire rope and a fixed pile. When encountering severe weather such as strong winds, workers will first connect one end of the steel wire rope to the stacker boom, and then tie the other end to the fixed pile on the ground. Through this connection method, the steel wire rope can effectively pull and stabilize the stacker boom, ensuring that it will not move or swing under the action of wind.

[0004] However, in actual operation, when workers tighten the wire rope in a strong wind environment, they are easily affected by the wind and lose their balance, resulting in falling and injury. In addition, when workers tie the wire rope, it is difficult to ensure that the wire rope is firmly tightened. This unstable fixed state may cause the stacker boom to topple over, posing a serious safety hazard. Summary of the invention

[0005] The utility model aims at solving the problems that workers are prone to falling and getting injured and the stacker cantilever is prone to tipping over when anchoring the stacker cantilever, and provides an automatic anchoring device for the stacker cantilever which can achieve the goal of not causing injuries to workers and not causing tipping over of the stacker cantilever when anchoring the stacker cantilever.

[0006] To solve the above problems, the technical solution adopted by the utility model is a kind of automatic anchoring device for the boom of a stacker, which includes a mounting frame. A connecting seat is fixed on the top of the mounting frame, and a connecting head is installed on the connecting seat. The connecting head can be fixed on the boom of the stacker. Fixed clamping seats are arranged on both sides of the connecting head, and the fixed clamping seats can be fixed on the boom of the stacker. Two limiting grooves are arranged on the top of the mounting frame, and the two limiting grooves are distributed on both sides of the connecting seat. Fixed clamping pins are installed in the limiting grooves, and a driving mechanism is arranged on the fixed clamping pins. The driving mechanism can make the fixed clamping pins snap into the fixed clamping seats. The connecting head and the fixed clamping seats are fixed on the boom of the stacker. When it is necessary to fix the boom of the stacker, only need to move the boom of the stacker to accurately dock the connecting head to the connecting seat. The driving mechanism controls the two fixed clamping pins to slide along the limiting grooves, so that the two fixed clamping pins are respectively accurately embedded into the fixed clamping seats on both sides of the connecting head, thereby locking the boom of the stacker on the mounting frame. Therefore, this device realizes the automatic anchoring and fixing of the boom of the stacker, significantly reduces the working risk, and avoids the possibility of workers being injured. At the same time, through anchoring on both sides at the same time, the stability and safety of the boom of the stacker are ensured, and the risk of tipping is greatly reduced.

[0007] Preferably, the driving mechanism includes a servo electric cylinder. The moving direction of the push rod of the servo electric cylinder is parallel to the length direction of the limiting groove, and the push rod of the servo electric cylinder is fixedly connected to the bottom of the fixed clamping pin. The moving direction of the push rod of the servo electric cylinder is parallel to the length direction of the limiting groove. By precisely controlling the telescopic action of the push rod of the servo electric cylinder, it can ensure that the fixed clamping pin slides accurately and smoothly along the limiting groove, so that the fixed clamping pin can accurately snap into or disengage from the fixed clamping seat.

[0008] Preferably, position sensors are arranged at both ends of the limiting groove. When the fixed clamping pin slides to both ends of the limiting groove, the position sensors will quickly respond and accurately transmit signals to the driving mechanism to make it stop working immediately, so as to ensure the stable stop of the fixed clamping pin.

[0009] Preferably, a bracket is fixed to the bottom of the mounting frame. The bracket provides a stable supporting function for the mounting frame.

[0010] Preferably, a control cabinet is fixed on the bracket. The control cabinet is installed on the bracket, which is convenient for the staff to repair when the device fails.

[0011] Preferably, a support plate is fixed to the top of the bracket, and the mounting frame is fixed on the support plate. The support plate significantly enhances the fixed connection between the bracket and the mounting frame, ensuring that the mounting frame can be stably and firmly installed on the bracket.

[0012] Preferably, it further includes a monitoring camera, and the monitoring camera can be fixed on the boom of the stacker. Workers can monitor the running state of this device in real time through the monitoring camera. Once any failure occurs to the device, workers can immediately discover and respond.

[0013] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: When the connection head of the boom of the stacking machine is docked with the connection seat, the driving mechanism will control the two fixed pins to slide precisely along the limiting groove to ensure that the two fixed pins are respectively inserted into the fixed seat cards on both sides of the connection head, thereby realizing the automatic anchoring and fixing of the boom of the stacking machine on the mounting frame. To sum up, the device realizes the automatic anchoring and fixing of the boom of the stacking machine, significantly reduces the working risk, and avoids the possibility of workers being injured. At the same time, through the simultaneous anchoring on both sides, the stability and safety of the boom of the stacking machine are ensured, and the risk of tipping is greatly reduced.
