Description

Technical Field

[0001] This utility model belongs to the field of gantry crane technology, and in particular relates to an anti-collision sensing device for gantry cranes. Background Technology

[0002] Gantry cranes are widely used in factories, warehouses, and docks for lifting and transferring equipment and workpieces within the factory grounds. Because workers use handheld remote controls to lift objects, the operator's view can be obstructed by other objects while the crane is in motion, posing a safety risk of collision. To ensure safe lifting operations, technicians have installed infrared anti-collision sensors in front of the gantry crane. When the crane is moving while lifting an object, the infrared sensor sends an infrared signal with a sensing range of 0-2 meters forward. If a person is within 2 meters in front of the crane, the sensor receives the reflected signal and transmits it to the crane's main control circuit, causing the crane to stop and preventing injury.

[0003] However, during the application of this technology, the equipment is easily affected by various heat sources and light sources when used in outdoor environments. Furthermore, when the ambient temperature is close to the human body temperature, the detection and sensitivity of the infrared sensor will decrease significantly, sometimes causing short-term malfunctions. There is a technical problem that the sensor cannot be isolated and cooled for protection to ensure its anti-collision sensing sensitivity and avoid accidents. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a gantry-type collision avoidance sensing device for vehicles, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a gantry-type anti-collision sensing device for vehicles, comprising a vehicle body, and further comprising: an alarm installed at the rear end of the top of the vehicle body; an infrared sensor installed at the top of the front end of the vehicle body; a protective cover installed outside the infrared sensor at the top of the front end of the vehicle body; a negative pressure fan installed on one side inside the protective cover; a ventilation slot installed on the other side inside the protective cover; stabilizing slots installed at the front ends of both sides of the vehicle body; mounting strips installed at the rear ends of both sides inside the protective cover; and disassembly and positioning components installed at the front end of the vehicle body and the rear end of the infrared sensor.

[0007] Furthermore, the protective cover is U-shaped, the output end of the negative pressure fan is located on the outside of the protective cover, and the ventilation slots are arranged at equal intervals on the other side inside the protective cover.

[0008] Furthermore, the mounting strips are symmetrically arranged on the inside of the protective cover, and the mounting strips are inserted into the interior of the stabilizing slot.

[0009] Furthermore, the disassembly and positioning assembly includes a fixed bracket, which is fixedly connected to the top of the front end of the vehicle body. A connecting bracket is provided at the rear end of the infrared sensor. A stabilizing strip is provided at the bottom of the inner rear end of the connecting bracket. A limiting groove is provided at the bottom of the inner front end of the fixed bracket.

[0010] Furthermore, the connecting card holder is U-shaped, the bottom of the inner rear end of the connecting card holder is chamfered, and the vertical cross-section of the stabilizing strip is semi-circular.

[0011] Furthermore, the rear end of the connecting card holder is inserted into the inner side of the fixed card seat, and the stabilizing card strip is embedded into the interior of the limiting groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model provides a protective component for the infrared sensor located at the top front of the vehicle body. In use, the protective cover is attached to the front of the vehicle body, and the mounting strip is inserted into the corresponding stable slot. This allows the protective cover to be stably installed outside the infrared sensor at the front of the vehicle body. The protective cover protects the infrared sensor from rain and snow, while also preventing interference from various heat sources and light sources that could lead to a decrease in sensor performance or false alarms. Furthermore, in hot weather, a negative pressure fan can be activated in conjunction with the ventilation slot to accelerate the airflow inside the protective cover, reducing the operating temperature of the infrared sensor inside the cover and preventing overheating that could reduce the detection and sensitivity of the infrared sensor or even cause it to malfunction.

[0014] This invention features a disassembly and positioning assembly at the front end of the vehicle body and the rear end of the infrared sensor. During use, the rear end of the connecting bracket is inserted into the fixed bracket, and the stabilizing strip is engaged with the limiting groove, thus securing the connecting bracket within the fixed bracket. This allows for stable installation of the infrared sensor at the front end of the vehicle body. Pushing the rear end of the connecting bracket backward removes the stabilizing strip from the limiting groove, and pulling the connecting bracket upward allows for easy removal of the infrared sensor. This facilitates convenient and quick installation, fixation, and disassembly of the infrared sensor, enabling easy replacement or maintenance of the anti-collision sensor components.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a collision avoidance sensing device for a gantry crane, including a crane body 1, and further including: an alarm 6 installed at the rear end of the top of the crane body 1, and an infrared sensor 4 installed at the top of the front end of the crane body 1. Using the crane's main control circuit distribution box, three wires are used to connect the crane's limit switch, relay, and infrared sensor 4, and simultaneously connect the alarm 6. When the crane is lifting an object, the infrared sensor 4 sends an infrared signal with a sensing distance of 0-2 meters forward. If there is a person within 2 meters in front of the crane, the sensor will receive the reflected sensing signal and immediately transmit the sensing signal to the crane's main control circuit, causing the crane to cut off power, stop working, and sound an alarm to prevent injury to people. A U-shaped protective cover 2 is installed outside the infrared sensor 4 at the top front end of the crane body 1. Stabilizing slots 8 are installed at the front ends of both sides of the crane body 1. Mounting strips 7 are provided at the rear ends on both sides. The mounting strips 7 are symmetrically arranged inside the protective cover 2. The mounting strips 7 are inserted into the inside of the stabilizing slot 8, so that the protective cover 2 can be stably installed outside the infrared sensor 4 at the front of the vehicle body 1. The protective cover 2 protects the infrared sensor 4 from rain and snow, and avoids interference from various heat sources and light sources, which may cause the sensor performance to degrade or false alarm. A negative pressure fan 3 is installed on one side inside the protective cover 2. The output end of the negative pressure fan 3 is located on the outside of the protective cover 2. A ventilation slot 5 is provided on the other side inside the protective cover 2. The ventilation slots 5 are arranged at equal intervals on the other side inside the protective cover 2. In hot weather, the negative pressure fan 3 can be activated in conjunction with the ventilation slot 5 to accelerate the airflow inside the protective cover 2, reduce the working environment temperature of the infrared sensor 4 inside the protective cover 2, and avoid the infrared sensor 4 from being desensitized or even malfunctioning due to overheating.

[0024] When in use, the protective cover 2 is attached to the front end of the vehicle body 1 and the mounting strip 7 is inserted into the corresponding stable slot 8. The protective cover 2 can be stably installed on the outside of the infrared sensor 4 at the front end of the vehicle body 1. The protective cover 2 protects the infrared sensor 4 from rain and snow. In hot weather, the negative pressure fan 3 can be started in conjunction with the ventilation slot 5 to speed up the air flow inside the protective cover 2 and reduce the working temperature of the infrared sensor 4.

[0025] As a further implementation of this embodiment, such as Figure 1-4As shown, the front end of the vehicle body 1 and the rear end of the infrared sensor 4 are provided with a disassembly and positioning assembly. The disassembly and positioning assembly includes a fixing bracket 9, which is fixedly connected to the top of the front end of the vehicle body 1. The rear end of the infrared sensor 4 is provided with a U-shaped connecting bracket 12, and the bottom of the inner rear end of the connecting bracket 12 is chamfered. The bottom of the inner rear end of the connecting bracket 12 is provided with a stabilizing strip 11, which has a semi-circular vertical cross-section. The bottom of the inner front end of the fixing bracket 9 is provided with a limiting groove 10. The rear end of the connecting bracket 12 is inserted into... The retaining strip 11 is inserted into the inner side of the fixed bracket 9 and embedded into the inner side of the limiting groove 10, thereby limiting the connecting bracket 12 within the fixed bracket 9. This achieves the purpose of stably installing the infrared sensor 4 at the front end of the vehicle body 1. Pushing the rear end of the connecting bracket 12 backward will remove the retaining strip 11 from the limiting groove 10, and pulling the connecting bracket 12 upward will remove the infrared sensor 4. This achieves the purpose of convenient and quick installation, fixing, and removal of the infrared sensor 4 to facilitate the disassembly, replacement, or maintenance of the anti-collision sensor components.

[0026] Working principle: When using the anti-collision sensing device, first insert the rear end of the connecting bracket 12 into the interior of the fixed bracket 9, and simultaneously insert the stabilizing strip 11 into the interior of the limiting slot 10, thereby fixing the connecting bracket 12 within the fixed bracket 9. This allows the infrared sensor 4 to be stably installed at the front end of the vehicle body 1. Then, cover the front end of the vehicle body 1 with the protective cover 2 and insert the mounting strip 7 into the corresponding stabilizing slot 8. This stably installs the protective cover 2 outside the infrared sensor 4 at the front end of the vehicle body 1. When the vehicle is lifting an object, the infrared sensor 4 sends an infrared signal with a sensing distance of 0-2 meters forward. If the object is within 2 meters in front of the vehicle... If someone is present, the sensor will receive a reflected signal. The sensor will immediately transmit the signal to the vehicle's main control circuit, causing the vehicle to lose power, stop working, and sound an alarm to prevent injury. The protective cover 2 protects the infrared sensor 4 from rain and snow. In hot weather, the negative pressure fan 3 can be activated in conjunction with the ventilation slot 5 to accelerate the airflow inside the protective cover 2, reducing the operating temperature of the infrared sensor 4 and ensuring its sensitivity. When the infrared sensor 4 needs to be replaced or maintained, push the rear end of the connecting bracket 12 backward to remove the retaining strip 11 from the limiting slot 10, and then pull the connecting bracket 12 upward to remove the infrared sensor 4.

[0027] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
