Description

Technical Field

[0001] The utility model relates to the technical field of gantry crane arm frames, in particular to an anti-collision alarm device for a gantry crane arm frame. Background Art

[0002] In order to ensure the efficiency of loading and unloading, port gantry cranes usually encounter situations where they are concentrated in a certain area for joint operations. When encountering situations such as multiple machines grabbing materials at the same cargo ship's hold, the distance between two adjacent gantry cranes will be closer.

[0003] However, since the arm span of a gantry crane often reaches thirty to forty meters, there is often a risk of arm collision when working together. The arm of the gantry crane moves in a circular motion and cooperates with the amplitude variation motion. The traditional sensor-type collision detection device is limited by the installation method and detection angle, and often cannot cope with this more complex motion state and has a certain detection blind spot. It is impossible to perform anti-collision alarm operations for two adjacent groups of port gantry cranes in the first time, and cannot meet daily use needs. Therefore, it is urgent to design a gantry crane arm anti-collision alarm device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a gantry crane boom anti-collision alarm device to solve the problem raised in the above background technology that since the arm span of the gantry crane often reaches thirty to forty meters, there is often a risk of arm collision when working together, and the arm of the gantry crane performs circular motion and cooperates with variable amplitude motion. The traditional sensor-type collision detection device is limited by the installation method and detection angle, and often cannot cope with this relatively complex motion state and has a certain detection blind spot. It is impossible to perform the anti-collision alarm operation of two adjacent groups of port gantry cranes in the first time, and cannot meet the daily use needs.

[0005] To achieve the above object, the utility model provides the following technical solutions: a gantry crane arm anti-collision alarm device, comprising a mounting support, a control room is provided on the surface of the mounting support, a grabbing arm is provided at one end of the control room, a grabbing arm is provided at one end of the grabbing arm, and a hoisting seat is provided at one end of the grabbing arm;

[0006] A connection frame is provided at the bottom of the mounting support.

[0007] Preferably, both ends of the connection frame are fixedly connected with connection seats, and an encoder is arranged inside the connection seat.

[0008] Preferably, a detection groove is provided at the center of the front side of the connection frame, and an infrared scattering mirror is provided on the inner wall of the detection groove.

[0009] Preferably, an infrared probe assembly is provided at the back of the detection tank.

[0010] Preferably, an angle sensor is provided between the mounting support and the control chamber.

[0011] Preferably, the two groups of control rooms are connected by electrical signals via a connection rack.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The anti-collision alarm device for the gantry crane boom can make the device perform more accurate anti-collision alarm operation between two groups of gantry crane booms through the installation support, control room, grabbing boom, grabbing arm, hoisting seat, connection frame, detection slot, infrared diffuser, infrared probe assembly and angle sensor. In actual use, when two groups of grabbing booms simultaneously control their own grabbing booms, grabbing arms and hoisting seats to grab materials at the same cargo ship's hold, once a group of grabbing booms, grabbing arms and hoisting seats rotates through the detection slot at the center of the connection frame, the infrared probe assembly can quickly capture the grabbing boom, grabbing arm and hoisting seat through the infrared scanning rays uniformly emitted by the angle sensor, and an alarm prompt will appear in the control room of the corresponding area in time, thereby forcing the corresponding control room to perform a material grabbing operation to the other side of the ship's hold. At the same time, the angle sensor between the installation support and the control room can also perform real-time rotation monitoring operations, more accurately avoiding the collision risk of the grabbing structures of the two control rooms, reflecting the practicality of the equipment design.

[0014] The gantry crane arm anti-collision alarm device further improves the overall use effect of the equipment through the installation support, connection frame, connection seat, encoder, detection slot, infrared diffuser, infrared probe group and angle sensor. In daily use, the corresponding trolley position, amplitude change distance, rotation angle, etc. of the gantry crane are first collected through measuring devices such as encoders and angle sensors, and these data are connected to the anti-collision control host. Communication lines or devices such as optical fiber reels are set on the gantry crane, and the terminal gantry crane unit is networked into a local area network, so that each arm anti-collision host can share the corresponding data resources on other machines. On the arm anti-collision system of any gantry crane, according to the data of trolley position, amplitude change length and rotation position, the gantry crane arm movement at a certain moment can be simulated as a line segment motion in a circular motion. Due to data sharing, the arm movement of adjacent gantry cranes can be monitored simultaneously on this machine, thereby fundamentally avoiding the possible operation collision problem between the gantry crane arms, which reflects the comprehensiveness of the equipment design.

Once a group of grabbing arm 3, grabbing arm 4 and lifting seat 5 rotate through a detection slot 9 at the center of the connecting frame 6, the infrared probe group 11 can quickly capture the grabbing arm 3, grabbing arm 4 and lifting seat 5 through the infrared scanning rays uniformly emitted by the angle sensor 12, and an alarm prompt will appear in the corresponding area control room 2 in time.

Communication lines or devices such as optical fiber reels are set on the gantry crane, and the terminal gantry crane unit is networked into a local area network, so that each boom anti-collision host can share the corresponding data resources on other machines.

[0024] Working principle: When in use, when two groups of grabbing arms 3 simultaneously control their own grabbing arms 3, grabbing arms 4 and lifting seats 5 to grab materials at the same cargo ship's hold, once a group of grabbing arms 3, grabbing arms 4 and lifting seats 5 rotate through the detection slot 9 at the center of the connecting frame 6, the infrared scanning rays uniformly emitted by the infrared probe group 11 through the angle sensor 12 can quickly capture the grabbing arms 3, grabbing arms 4 and lifting seats 5, and promptly display an alarm prompt in the corresponding area control room 2, thereby forcing the corresponding control room 2 to perform a grabbing operation on the other side of the ship's hold. At the same time, the angle sensor 12 installed between the support 1 and the control room 2 can also perform real-time rotation monitoring operations to more accurately avoid the risk of collision between the grabbing structures of the two control rooms 2. In daily During use, firstly, the corresponding trolley position, amplitude change distance, rotation angle, etc. of the gantry crane are collected through measuring devices such as encoder 8 and angle sensor 12, and these data are connected to the anti-collision control host. Communication lines or devices such as optical fiber reels are set on the gantry crane, and the terminal gantry crane unit is networked into a local area network, so that each boom anti-collision host can share the corresponding data resources on other machines.
