Description

Technical Field

[0001] The present invention relates to intelligent sensing technology on a container crane, and more particularly to a retractable sensor installation platform for avoiding collision. Background Art

[0002] In order to realize the automated operation of containers, it is necessary to detect the deviation between the container spreader and the container, the lifted container and the container below, the lifted container and the horizontal transport vehicle, etc. Existing solutions mostly use sensors installed under the trolley frame to achieve this function, but the distance between the trolley frame and the target is relatively far, especially the quay crane (usually more than 30 meters), resulting in low detection accuracy.

[0003] If the sensor can be installed on the spreader, the sensor can move closer to the target as the spreader moves, reducing the detection distance and improving the detection accuracy. However, there are two problems with installing the sensor on the spreader:

[0004] 1) In the actual operation process, the lifting device will generate a large impact load at the moment of landing, causing damage to the sensor;

[0005] 2) Since it is necessary to detect the relative position relationship between the hoisted container and the container below when the container is in the loaded state, the sensor needs to be installed outside the frame range of the hoist. As a result, during the operation, the sensor will directly collide with surrounding obstacles, causing damage to the sensor. Summary of the invention

[0006] In view of the defects existing in the prior art, the purpose of the present invention is to provide a retractable collision-avoiding sensor mounting platform, which can not only absorb the impact load generated by the sling during operation, but also actively retract the sensor to a safe position when a collision risk is detected.

DETAILED DESCRIPTION

[0041] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0042] Combination Figure 1 As shown, a retractable collision-avoiding sensor mounting platform provided by the present invention includes a protection component 1, a flip component 2, a sensor connection component 3, an anti-collision sensor connection component 4 and a motor component 5.

[0043] Combination Figure 2 As shown, the protection component 1 includes a steel structure frame 11 , an anti-collision sensor protection cover 12 and an aviation plug 13 .

[0044] The steel structure frame 11 provides effective protection for the entire sensor installation platform, and is provided with a plurality of installation holes for connecting various components.

[0045] There are two anti-collision sensor protection covers 12 symmetrically installed on both sides of the steel structure frame 11 , and are used to install the anti-collision sensor connection assembly 2 and provide effective protection for the anti-collision sensor connection assembly 2 .

[0046] The aviation plug 13 is provided on the steel structure frame 11 to provide power and control interface for the entire sensor installation platform. The aviation plug 13 can provide power to the rotating motor 52 and the sensor in the sensor installation platform, and the external controller can also obtain sensor data information or control the movement of the rotating motor 52 through the interface.

[0047] Combination Figure 3 As shown, the flip assembly 2 includes a fixing portion 21 and a flip portion 22 .

[0048] The fixing part 21 is firmly connected to the steel structure frame 11 of the protection component 1 through four fixing bolts 26 .

[0049] One end of the flip part 22 is rotatably connected to one end of the fixed part 21 via a through shaft 25 and a clamping spring 24 , and the flip part 22 rotates around the through shaft 25 .

[0050] The clamping spring 24 provides a certain torque, so that in a steady state, a certain angle can be formed between the flip part 22 and the fixed part 21, ensuring that the sensor located in the flip part 22 has an optimal perception field of view.

[0051] A rain cover 23 is also provided on the flip part 22 to prevent the sensor inside the flip part 22 from being corroded by rain.

[0052] Combination Figure 4 As shown, the sensor connecting assembly 3 includes a sensor connecting plate 31 , an angle adjustment mechanism 32 and a fixed base 33 .

[0053] The sensor is mounted on the sensor connecting plate 31 .

[0054] The sensor connecting plate 31 is mounted on the angle adjustment mechanism 32 by means of bolts.

[0055] After the angle adjustment is completed, the angle adjustment mechanism 32 is installed on the fixed base 33 through the pressing plate.

[0056] A movable structure is disposed on the left and right sides of the fixed base 33 , respectively. The movable structure includes a slide rail 35 and a slider 36 .

[0057] The slider is installed on the side of the fixed base 33 , the slide rail 35 is matched with the corresponding slider 36 , and the slider 36 moves on the slide rail 35 .

[0058] The slide rail 35 is connected to the flip part 22 of the flip assembly 2, so that the entire sensor can be retracted into the steel structure frame 11 of the entire protection assembly 1 as the flip part 22 moves, thereby preventing the sensor from being damaged.

[0059] A shock absorbing spring 34 is installed between the slide rail 35 and the slider 36 , and a shock absorbing spring 37 is installed between the slider 36 and the fixed base 33 , which can effectively absorb vibration and prevent the sensor from being damaged.

[0060] Combination Figure 5 As shown, there are two groups of anti-collision sensor connection components 4, which are respectively arranged on both sides of the sensor connection component 3. The anti-collision sensor connection components 4 each include an anti-collision sensor 41, a fixing bracket 42 and a slide rail 43.

[0061] The anti-collision sensor 41 is mounted on a fixing bracket 42 .

[0062] A through hole is formed in the middle of the fixing bracket 42 for the slide rail 43 to pass through.

[0063] The bottom of the slide rail 43 is connected to the steel structure frame 11 of the protection assembly 1 by bolts.

[0064] A shock absorbing spring is installed between the fixing bracket 42 and the slide rail 43 to protect the anti-collision sensor 41 .

[0065] Combination Figure 6 As shown, the motor assembly 5 includes a motor mounting plate 51 and a rotating motor 52 .

[0066] The rotary motor 52 is mounted on the motor mounting plate 51 .

[0067] The motor mounting plate 51 is firmly connected to the steel structure frame 11 of the protection component 1 through four spring-loaded shock-absorbing bolts 54 .

[0068] The output end of the rotating motor 52 drives a traction wire rope 53 , and the traction wire rope 53 is connected to the flip part 22 of the flip assembly 2 .

[0069] The retracting and extending actions of the flip part 22 are realized by controlling the forward and reverse rotation of the rotary motor 52.

[0070] Combination Figure 7 As shown, the sensor installation platform 100 of the present invention has a variety of installation schematic diagrams, such as Figure 7 As shown in (a), two sensor mounting platforms 100 of the present invention are installed at the bottom of the sling 200 near the side, as shown in FIG. Figure 7 As shown in (b), two sensor installation platforms 100 of the present invention are installed on the top of the hanger 200 near the side, as shown in FIG. Figure 7 As shown in (c), a sensor mounting platform 100 of the present invention is installed in the middle of the hanger 200 near the side.

[0071] The basic working principle of the sensor installation platform of the present invention is as follows:

[0072] The sensor installation platform of the present invention has two modes: active anti-collision and passive anti-collision. After the sensor installation platform of the present invention is installed, only the flip part 22 of the flip assembly 2 is exposed outside the steel structure of the sling, which has the risk of collision.

[0073] Passive anti-collision means that when the flip part 22 hits an obstacle and the impact force exceeds the torque provided by the torsion spring, the entire flip part 22 will quickly retract into the steel structure frame 11 of the protection component 1 to prevent damage to the sensor.

[0074] Active collision avoidance means that when the collision avoidance sensor 41 detects a collision risk, the controller controls the rotary motor 52 to rotate and retract the flip part 22 into the steel structure frame 11 of the protection component 1 to prevent the occurrence of a collision.

[0075] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.
