Description

Technical Field

[0001] This utility model relates to a mechanism for providing collision warning for mobile filling equipment in automobile assembly lines, belonging to the technical field of automobile mobile filling equipment. Background Technology

[0002] With the development of automation in the automotive manufacturing industry, mobile filling equipment in automobile assembly workshops usually needs to follow the production line in a complex environment to meet the high-speed material filling needs of automobiles on the assembly line.

[0003] However, existing mobile dispensing equipment has certain safety hazards during operation, as it is prone to collisions with other objects (such as material racks, operators, etc.), leading to equipment damage or even personal injury.

[0004] Currently, although some mobile refueling equipment is equipped with simple anti-collision devices, such as safety edge devices or simple limit switches, these devices have limited anti-collision effectiveness and cannot effectively prevent collision accidents. Therefore, developing an efficient and reliable anti-collision mechanism for mobile refueling equipment is of significant practical importance. Utility Model Content

[0005] This invention addresses the shortcomings of existing anti-collision technologies for mobile refueling equipment by providing a safety anti-collision early warning mechanism for mobile refueling equipment. This mechanism can effectively detect obstacles during the movement of the mobile refueling equipment and take timely measures to avoid collisions when obstacles are triggered, thereby improving the safety and reliability of the equipment.

[0006] To achieve the above objectives, the mobile refueling equipment anti-collision warning device of this utility model adopts the following technical solution:

[0007] The device includes a bracket and a safety contact edge. The safety contact edge is connected to the bracket via an anti-collision actuator. A photoelectric switch and a safety trigger switch detection plate are installed inside the safety contact edge. The safety trigger switch is installed on the bracket.

[0008] Both the through-beam switch and the safety trigger switch are connected to the control unit, which is also connected to the braking actuator. The control unit and the braking actuator are located within the mobile refueling equipment. The braking actuator employs either an electric brake or a hydraulic brake.

[0009] The anti-collision actuator is a linear bearing, which is mounted on a bracket, and the safety contact strip is connected to the moving shaft of the linear bearing.

[0010] A buffer mechanism is provided between the bracket and the safety contact edge. The buffer mechanism is a spring. The effective compression stroke of the spring is not less than 100mm.

[0011] One set of the above-mentioned device is installed at the front and rear of the mobile refueling equipment. The through-beam switch and the safety trigger switch are electrically connected to the control unit in the mobile refueling equipment. The safety contact strip and the detection piece of the safety trigger switch inside it move with the mobile refueling equipment. When the safety contact strip triggers an obstacle, it is squeezed and deformed, pushing the linear bearing's moving axis backward. The through-beam switch built into the safety trigger strip triggers a detection signal. After the safety trigger strip can no longer be squeezed and deformed, the obstacle continues to push the linear bearing, causing the detection piece of the safety trigger switch to contact the safety trigger switch. The relay inside the safety trigger switch is activated, sending a signal to the control unit in the mobile refueling equipment. The control unit outputs a control signal, activating the braking actuator to decelerate and stop the mobile refueling equipment.

[0012] This invention enables effective detection of obstacles during the movement of mobile refueling equipment and takes timely measures to avoid collisions when obstacles are triggered, thereby improving the safety and reliability of the equipment. In practical applications, it can effectively detect obstacles and take timely measures to slow down and brake when obstacles are triggered, thus improving the safety and reliability of the equipment. The combination of a through-beam switch and a safety trigger switch provides omnidirectional detection, intelligent control, and buffer protection, making it suitable for the collision avoidance needs of mobile refueling equipment in various complex environments. By configuring a dual anti-collision warning mechanism, the safety risks after switch failure are effectively resolved. Attached Figure Description

[0017] The mobile refueling equipment anti-collision warning device of this utility model, such as Figure 1 As shown, the system includes a bracket 6, a safety contact strip 1, linear bearings 2, a safety trigger switch 3, a safety trigger switch detection plate 4, and a buffer spring 5. Two linear bearings 2 are mounted on the bottom of the bracket 6 (the outer rings of the linear bearings 2 are mounted on the bracket 6), and the safety contact strip 1 is connected to the moving shafts 7 of the two linear bearings 2.

[0018] The safety contact edge 1 is equipped with a through-beam switch and a safety trigger switch detection piece 4, which moves together with the safety contact edge 1. The safety trigger switch 3 is mounted on the bracket 6.

[0019] A buffer spring 5 is mounted on the moving shaft 7 of the linear bearing 2. The buffer spring 5 is located between the safety contact strip 1 and the bracket 6 (or the linear bearing 2). The effective compression stroke of the buffer spring 5 should be no less than 100 mm.

[0020] Both the through-beam switch and the safety trigger switch 3 are connected to the control unit, which is also connected to the braking actuator. The control unit and the braking actuator are located within the mobile refueling equipment. The braking actuator can be an electric brake or a hydraulic brake. The control unit receives obstacle information detected by the through-beam switch and the safety trigger switch 3 and issues a command to activate the braking actuator. Based on the operating status of the mobile refueling equipment, the actuator brakes the equipment quickly and smoothly until it stops moving.

[0021] The working principle of the above-mentioned mechanism is as follows.

[0022] When the safety contact strip 1 triggers an obstacle, it deforms under pressure, pushing the linear bearing 2's moving shaft 7 backward, compressing the buffer spring 5. During the movement of the safety contact strip 1 and the moving shaft 7, the safety contact strip 1 first deforms under pressure, triggering a detection signal from the built-in through-beam switch. After the safety contact strip 1 can no longer be deformed, the obstacle continues to push the linear bearing 2, causing the safety contact switch detection piece to contact the safety contact switch 3. At this point, the relay inside the safety contact switch 3 engages, sending a signal to the control unit in the mobile dispensing equipment. The control unit receives the signals from the safety contact switch 3 and the built-in through-beam switch in the safety contact strip 1, and outputs a control signal to decelerate and stop the mobile dispensing equipment.

[0023] like Figure 2 As shown, the mobile refueling equipment anti-collision warning device of this utility model consists of a warning mechanism installed at both the front and rear ends of the mobile refueling equipment, namely a front anti-collision mechanism 9 and a rear anti-collision mechanism 8. By configuring dual anti-collision warning mechanisms, the safety risks after switch failure are effectively solved.

[0024] The mobile refueling equipment anti-collision warning device has an effective compression stroke of 100mm, which is used to absorb some of the energy in the event of a collision and to decelerate and brake within this stroke to prevent the impact of sudden braking collisions on the equipment.
