Description

Technical Field

[0001] The utility model relates to the technical field of goods detection, in particular to a multi-radar combined goods detection device. Background Technique

[0002] As a transfer station for unloading ships at ports by sea-going vessels, during use, goods are hoisted into the hopper by a crane. The loading vehicle is driven into the lower end of the hopper discharge port in advance, and the goods are filled into the truck through the hopper discharge port for mobile transportation.

[0003] At present, when the vehicle for unloading ships enters the hopper to discharge goods, it is usually manually operated. The discharge volume mainly depends on manual experience, which easily leads to overweighing or underweighing of goods. Overloading not only increases the hidden danger of vehicle driving, but also for overweighed vehicles, the driver has to unload goods midway to ensure that the vehicle is not overloaded, affecting the operation efficiency.

[0004] Therefore, we propose a multi-radar combined goods detection device to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-radar combined goods detection device to solve the problems in the above-mentioned background technique that when the vehicle for unloading ships enters the hopper to discharge goods, it is usually manually operated. The discharge volume mainly depends on manual experience, which easily leads to overweighing or underweighing of goods. Overloading not only increases the hidden danger of vehicle driving, but also for overweighed vehicles, the driver has to unload goods midway to ensure that the vehicle is not overloaded, affecting the operation efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A multi-radar combined goods detection device, including a unloading hopper and a support assembly arranged around the outer wall of the unloading hopper. The outer surface of the lower end of the unloading hopper is fixedly installed with a shielding assembly around the periphery. The bottom end of the shielding assembly is fixedly installed with a detection assembly around the periphery, and the detection assembly is adapted to monitor the loading condition of the unloading vehicle. The upper end of the detection assembly is fixedly installed with a docking assembly, and the docking assembly is adapted to fixedly install the detection assembly.

[0007] The detection assembly includes a receiving mechanism and a high-frequency radar detection mechanism fixedly installed in the inner cavity of the receiving mechanism. One end of the receiving mechanism is threadedly connected with a protection mechanism. The high-frequency radar detection mechanism is fixedly installed through the receiving mechanism, and the protection mechanism is used to protect the outer surface of the high-frequency radar detection mechanism.

[0008] Preferably, the receiving mechanism includes a hollow circular block and a threaded half groove opened in the middle of the outer periphery of the upper end of the hollow circular block. Threaded circular grooves are opened on both sides of the inner wall of the hollow circular block.

[0009] Preferably, a long threaded rod is threadedly connected in the inner cavity of the threaded circular groove, and a bearing is fixedly installed at one end of the long threaded rod, and a semi-circular clamping plate is fixedly installed at one end of the bearing.

[0010] Preferably, the protection mechanism includes a fitting circular ring and a hollow threaded ring fixedly installed in the middle of the lower end of the fitting circular ring.

[0011] Preferably, a circular frame is fixedly installed at the upper end of the fitting circular ring, and a protective net is embedded around the outer surface and the top surface of the circular frame.

[0012] Preferably, the docking assembly includes a T-shaped fixed plate and circular threaded grooves respectively opened on both sides of the upper end of the T-shaped fixed plate, and fixed screws are threadedly connected in the inner cavities of the circular threaded grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When loading goods into the freight car compartment, since the unloading hopper has different specific gravities of goods, when loading a pile of goods, the vehicle enters the hopper to start discharging. All four high-frequency radar detection mechanisms are activated. When any one of the high-frequency radar detection mechanisms detects that the height of the goods in the compartment reaches the set value, the hopper door closes and the vehicle is prompted to leave. When two piles of goods need to be loaded, when the vehicle enters the hopper and any one of the high-frequency radar detection mechanisms on either side first detects the vehicle, the direction in which the vehicle enters the hopper is judged. For the first pile of goods, all four high-frequency radar detection mechanisms work simultaneously. After detecting that the material reaches the set height, the high-frequency radar detection mechanism stops working and the vehicle is prompted to move for the second pile of goods. After 10 seconds, the high-frequency radar detection mechanism is activated again. When the vehicle enters, the high-frequency radar detection mechanism has already judged the direction in which the vehicle enters. For example, if the vehicle is traveling from east to west, then the second pile of goods will be detected by the two high-frequency radar detection mechanisms on the west side, and the high-frequency radar detection mechanisms on the east side will not detect. After detecting that the material reaches the set height, the hopper door is closed and the vehicle is prompted to leave. By detecting the material with the east and west groups of high-frequency radar detection mechanisms, the weights of one pile of goods and two piles of goods are ensured to be consistent, improving the vehicle transportation efficiency.

[0015] 2. By placing the high-frequency radar detection mechanism into the inner cavity of the hollow circular block and respectively rotating the long threaded rods threadedly connected to both sides of the inner wall of the hollow circular block, the long threaded rods drive the semi-circular clamping plates to clamp and fix the high-frequency radar detection mechanism. By threadedly fixing and installing the T-shaped fixed plate at the installation position at the lower end of the shielding assembly with fixed screws, the installation of the set position of the high-frequency radar detection mechanism can be completed.

Detailed implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4 , a multi - radar combined cargo detection device, including an unloading hopper 1 and a support assembly 2 arranged around the outer wall of the unloading hopper 1. The outer surface of the lower end of the unloading hopper 1 is fixedly installed with a shielding assembly 3 around the perimeter. The bottom end of the shielding assembly 3 is fixedly installed with a detection assembly 4 around the perimeter. The detection assembly 4 is adapted to monitor the loading condition of the unloading vehicle. The upper end of the detection assembly 4 is fixedly installed with a docking assembly 5, and the docking assembly 5 is adapted to fixedly install the detection assembly 4.

[0024] The detection assembly 4 includes an accommodation mechanism 41 and a high - frequency radar detection mechanism 42 fixedly installed in the inner cavity of the accommodation mechanism 41. One end of the accommodation mechanism 41 is threadedly connected with a protection mechanism 43. The high - frequency radar detection mechanism 42 is fixedly installed through the accommodation mechanism 41, and the protection mechanism 43 is used to protect the outer surface of the high - frequency radar detection mechanism 42.

[0025] The model of the high - frequency radar detection mechanism 42 is VEGAPULSC11.

[0026] In this embodiment: a high-frequency radar detection mechanism 42 is installed at each of the four corners of the lower end of the shielding component 3 to detect the materials in the truck compartment. When the truck compartment is loaded, due to the different specific gravity of the goods in the unloading hopper 1, sometimes one pile of goods is needed, and sometimes two piles of goods are needed. When one pile of goods is placed, the vehicle enters the hopper and starts to discharge the materials. The four high-frequency radar detection mechanisms 42 are all started. Any high-frequency radar detection mechanism 42 detects that the height of the cargo in the compartment reaches the set value, and the hopper door is closed to prompt the vehicle to leave. If two piles of materials need to be placed, the high-frequency radar detection mechanism 42 on either side of the vehicle entering the hopper first detects the vehicle, and then determines the direction of the vehicle entering the hopper, such as: driving from east to west or from west to east. For the first pile of materials, the four high-frequency radar detection mechanisms 42 work simultaneously. When it is detected that the material reaches the set height After that, the high-frequency radar detection mechanism 42 stops working, prompting the vehicle to move to place the second pile of materials. After 10 seconds, the high-frequency radar detection mechanism 42 starts working again. When the vehicle enters, the high-frequency radar detection mechanism 42 has determined the direction of the vehicle's entry. For example, if it is traveling from east to west, the second pile of materials will be detected by the two high-frequency radar detection mechanisms 42 on the west side, and the high-frequency radar detection mechanism 42 on the east side will not perform any detection. After detecting that the material has reached the set height, the bucket gate is closed to prompt the vehicle to leave. The materials are detected by the east and west groups of high-frequency radar detection mechanisms 42, and real-time data is transmitted, which not only ensures that the vehicle is not overloaded or underweight when there is one pile of goods, but also accurately controls the amount of goods when placing two piles of goods, ensures that the weight of one pile and two piles of goods is consistent, improves vehicle loading balance, improves vehicle transportation efficiency, and improves vehicle transportation safety.

[0027] Example 2

[0028] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3 The accommodating mechanism 41 includes a hollow circular block 411 and a threaded half groove 412 opened in the middle of the outer circumference of the upper end of the hollow circular block 411 , and threaded circular grooves 413 are opened on both sides of the inner wall of the hollow circular block 411 .

[0029] A long threaded rod 414 is threadedly connected in the inner cavity of the threaded circular groove 413, a bearing 415 is fixedly installed at one end of the long threaded rod 414, and a semi-arc clamping plate 416 is fixedly installed at one end of the bearing 415. The long threaded rod 414 is threadedly installed in the inner cavity of the threaded circular groove 413. When the threaded circular groove 413 moves, it will drive the bearing 415 and the semi-arc clamping plate 416 to move together in the inner cavity of the hollow round block 411.

[0030] The docking assembly 5 includes a T-shaped fixing plate 51 and circular thread grooves 52 respectively opened on both sides of the upper end of the T-shaped fixing plate 51. The inner cavity of the circular thread groove 52 is threadedly connected with a fixing screw 53. The T-shaped fixing plate 51 is fixedly installed on the lower end of the shielding assembly 3 by the fixing screw 53.

[0031] The protection mechanism 43 includes a fitting ring 431 and a hollow screw ring 432 fixedly installed at the middle part of the lower end of the fitting ring 431. The hollow screw ring 432 is threadedly connected to the inner cavity of the threaded half groove 412, thereby driving the fitting ring 431 to be placed on the upper end of the hollow block 411, so that the circular frame 433 drives the protection net 434 to be arranged around the upper end of the hollow block 411.

[0032] A circular frame 433 is fixedly installed at the upper end of the fitting ring 431. The protection net 434 is embedded around the outer surface and on the top surface of the circular frame 433 to block the splashing of objects.

[0033] In this embodiment: When installing the high-frequency radar detection mechanism 42, by placing the high-frequency radar detection mechanism 42 into the inner cavity of the hollow block 411 and respectively rotating the long threaded rods 414 threadedly connected to both sides of the inner wall of the hollow block 411, the long threaded rods 414 are rotated threadedly to drive the semi-arc clamping plates 416 to clamp and fix the high-frequency radar detection mechanism 42, and thus the installation of the high-frequency radar detection mechanism 42 can be completed. By using the fixing screws 53 to threadedly and fixedly install the T-shaped fixing plate 51 at the lower installation position of the shielding assembly 3, the installation of the setting position of the high-frequency radar detection mechanism 42 can be completed. By threadedly connecting the hollow screw ring 432 to the inner cavity of the threaded half groove 412, the circular frame 433 drives the protection net 434 to protect the outer periphery of the high-frequency radar detection mechanism 42, improving the safety of using the high-frequency radar detection mechanism 42.

[0034] Working principle: By placing the high-frequency radar detection mechanism 42 into the inner cavity of the hollow circular block 411, rotate the long threaded rods 414 threadedly connected to both sides of the inner wall of the hollow circular block 411 respectively, so that the threaded rotation of the long threaded rods 414 drives the semi-circular clamping plates 416 to clamp and fix the high-frequency radar detection mechanism 42, and the installation of the high-frequency radar detection mechanism 42 can be completed. By using the fixing screw 53 to threadedly fix and install the T-shaped fixing plate 51 at the lower installation position of the shielding assembly 3, the installation of the set position of the high-frequency radar detection mechanism 42 can be completed. When loading goods into the freight car compartment, since the unloading hopper 1 has different specific gravities of goods, sometimes a pile of goods needs to be placed, and sometimes two piles of goods need to be placed. When placing a pile of goods, the vehicle enters the hopper and starts discharging. All four high-frequency radar detection mechanisms 42 are activated. When any one of the high-frequency radar detection mechanisms 42 detects that the height of the goods in the compartment reaches the set value, the hopper door closes, and the vehicle is prompted to leave. When two piles of materials need to be placed, when the high-frequency radar detection mechanism 42 on any side of the vehicle detects the vehicle first when the vehicle enters the hopper, it is judged the direction of the vehicle entering the hopper, such as driving from east to west or from west to east. For the first pile of materials, the four high-frequency radar detection mechanisms 42 work simultaneously. After detecting that the materials reach the set height, the high-frequency radar detection mechanism 42 stops working, and the vehicle is prompted to move for the second pile of discharging. After 10 seconds, the high-frequency radar detection mechanism 42 starts working again. When the vehicle enters, the high-frequency radar detection mechanism 42 has already judged the direction of the vehicle entering. If it is driving from east to west, then the two high-frequency radar detection mechanisms 42 on the west side will perform the detection work for the second pile of materials, and the high-frequency radar detection mechanisms 42 on the east side will not perform the detection. After detecting that the materials reach the set height, the hopper door is closed, and the vehicle is prompted to leave. By using the two groups of high-frequency radar detection mechanisms 42 on the east and west sides to detect the materials and transmit real-time data, it not only ensures that the vehicle is not overloaded or underweight in the case of a pile of goods, but also accurately controls the quantity of goods when placing two piles of goods, ensures that the weights of a pile of goods and two piles of goods are the same, improves the loading balance of the vehicle, improves the transportation efficiency of the vehicle, and enhances the transportation safety of the vehicle.

The content protected by the present utility model does not involve improvements to software and methods either.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
