Description

Technical Field

[0001] This utility model relates to the technical field of transfer equipment in continuous casting process, and in particular to a flatbed truck safety anti-collision device and transfer vehicle. Background Technology

[0002] Flatbed transport vehicles are a type of electric rail transport equipment widely used in industrial plants. They have significant advantages such as simple structure, convenient operation, low maintenance cost, and strong load-bearing capacity, and are therefore widely used in metallurgy, machinery manufacturing and other fields.

[0003] In the specific working environment of a continuous casting workshop, the use of flatbed transfer carts poses safety hazards. Due to the special nature of the continuous casting process, the goods that the transfer carts need to carry are usually extremely heavy components such as sector sections and tundishes, often weighing tens or even hundreds of tons. During transportation, the excessive load increases the inertia of the vehicle during starting and braking, making it difficult for operators to precisely control the vehicle's speed and stopping position. Especially in high-traffic areas of the workshop, this difficulty in control can easily lead to collisions: on the one hand, it may cause injuries to passing personnel, endangering worker safety; on the other hand, a severe collision can damage the cart's structure, affecting its normal use. More seriously, once an accident occurs, it will not only cause personal injury and property damage, but also delay the material transfer schedule of the entire continuous casting production line, resulting in huge economic losses for the company.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1-3 As shown, this utility model discloses a flatbed truck safety anti-collision device, comprising:

[0026] The vehicle body 1 has buffer mechanisms 11 symmetrically arranged on both sides of the vehicle body 1 in the direction of movement, and rollers 12 are provided at the bottom of the vehicle body 1.

[0027] The drive assembly 2 includes a drive source 21 and a reducer 22. The drive source 21 is located at the bottom of the vehicle body 1, and the output end of the drive source 21 is connected to the reducer 22. The reducer 22 drives the roller 12 to rotate.

[0028] The detection component 3 includes a pair of laser rangefinders 31 and a control module 33. The pair of laser rangefinders 31 are symmetrically arranged on both sides of the vehicle body 1 in the direction of movement. The control module 33 is electrically connected to the laser rangefinders 31 and the drive source 21. A sound and light alarm 32 is also installed on both sides of the vehicle body 1 in the direction of movement. The sound and light alarm 32 is electrically connected to the control module 33.

[0029] In this invention, the vehicle body 1 is driven by a drive source 21 to drive a reducer 22, which in turn drives axle 23 to rotate. Axle 23 then drives roller 12 to rotate, thus enabling the entire vehicle body 1 to move. The laser rangefinder 31 in the detection assembly 3 is positioned at both ends of the vehicle body 1 in the direction of movement. It can monitor the distance between the vehicle and obstacles in front or behind in real time. When the distance is too close, the system automatically reduces the vehicle speed or applies emergency braking to avoid a collision. Specifically, the laser rangefinder 31 uses the TOF (Time-of-Flight) ranging principle to monitor the distance between the vehicle and obstacles in real time. The laser rangefinder 31 feeds back the detection signal to the control module 33. The control module 33 has a control program internally programmed. A preset safety threshold is input. When the detected obstacle distance is less than the preset safety threshold, the control module 33 controls the drive source 21 to automatically reduce the vehicle speed. If the distance continues to shorten to within 1.5m, emergency braking is triggered. Furthermore, the audible and visual alarm 32 achieves its warning function through both sound and light signals. In noisy environments, sound alone may be masked, while light (such as flashing lights) can create a strong visual stimulus; in dimly lit places, sound can overcome visual limitations. The combination of the two can attract people's attention to the greatest extent and ensure that the warning information is received quickly. In actual use, the control module 33 feeds back the detection signal to the audible and visual alarm 32, and the alarm will emit a high-frequency buzzer and flash warning lights to remind people in the vicinity to take precautions and prevent safety accidents from occurring.

[0030] This invention also includes a buffer mechanism 11, and a pair of buffer mechanisms 11 are symmetrically arranged at both ends of the vehicle body 1 in the direction of movement, serving as a mechanical anti-collision mechanism for the vehicle body 1. When the laser rangefinder 31 fails, the buffer mechanisms 11 on both sides of the vehicle body 1 come into direct contact with the obstacle, buffering and absorbing the impact force generated by the collision, thereby minimizing the risk of accidents.

[0031] The laser rangefinders 31 at both ends of the vehicle body 1 can monitor the distance between the vehicle and obstacles in front or behind in real time, and issue warning signals through the sound and light alarm 32, which can effectively reduce collision accidents caused by operational errors or blind spots. This not only protects the safety of on-site workers, but also avoids equipment damage, improves production efficiency, and reduces safety hazards.

[0032] Furthermore, a storage battery 15 is installed at the bottom of the vehicle body 1, and the storage battery 15 is electrically connected to the drive source 21 and the control module 33 respectively.

[0033] Specifically, in this utility model, the battery 15 can output electrical energy to the drive source 21 to drive the drive source 21 to rotate; at the same time, it can also supply power to the control module 33 for the transmission of signals from the laser rangefinder 31 and the audible and visual alarm 32.

[0034] Furthermore, marker lights 34 are provided on both sides of the vehicle body 1 in the direction of movement, and the marker lights 34 are electrically connected to the battery 15.

[0035] Specifically, the transfer vehicle in this invention is used in a continuous casting workshop where the lighting is dim. High-brightness LED marker lights 34 are used to ensure clear identification of the vehicle's outline even in low light conditions. This reminds operators in the workshop of the transfer vehicle's location, further enhancing safety.

[0036] Furthermore, a pair of limiting plates 13 are provided on the top surface of the vehicle body 1, and the pair of limiting plates 13 are arranged on both sides of the vehicle body 1 in the direction of movement.

[0037] Specifically, two limiting plates 13 are set on both sides of the vehicle body 1 in the direction of movement. During the actual transfer process, the product to be transferred is placed between the two limiting plates 13 to prevent the product from overturning due to the large inertia of the entire vehicle body 1 when the vehicle stops suddenly, thus further improving safety and reliability.

[0038] Furthermore, the buffer mechanism 11 includes a fixed rod 111, a telescopic rod 112, and a buffer plate 113. The fixed rod 111 is connected to the vehicle body 1. One end of the telescopic rod 112 passes through the fixed rod 111, and the other end of the telescopic rod 112 is connected to the buffer plate 113. An elastic element 115 is provided between the telescopic rod 112 and the fixed rod 111.

[0039] Specifically, one side of the buffer plate 113 in the entire buffer mechanism 11 is in direct contact with the obstacle. The buffer plate 113 is compressed by the telescopic rod 112, causing the telescopic rod 112 to shorten. Due to the elastic element 115 between the telescopic rod 112 and the fixed rod 111, the impact force generated by the impact can be absorbed and buffered, reducing the damage of vibration to goods, vehicles and related components.

[0040] Furthermore, a buffer pad 114 is provided on the surface of the buffer plate 113 away from the telescopic rod 112.

[0041] Specifically, the cushioning pad 114 can further absorb the impact force. As a preferred embodiment of this utility model, the cushioning pad 114 is made of rubber. It utilizes the elastic deformation and internal friction of rubber to consume energy, and has both cushioning and sound insulation effects, as well as good wear resistance.

[0042] Furthermore, the buffer pad 114 and the buffer plate 113 are detachably connected. Specifically, the buffer pad 114 and the buffer plate 113 are connected by bolts, so that the buffer pad 114 can be replaced after it is worn.

[0043] Furthermore, the surface of the top of the vehicle body 1 is provided with anti-slip texture 14.

[0044] Specifically, the anti-slip texture 14 on the top of the vehicle body 1 can increase the friction between the transported product and the vehicle body 1, preventing the product from tipping over due to inertial sliding when the vehicle body 1 stops suddenly, thereby further improving the safety and reliability of the transport vehicle.

[0045] A transfer vehicle includes the flatbed truck safety anti-collision device described in the above embodiments.

[0046] In summary, this utility model introduces a flatbed truck safety anti-collision device and a transfer vehicle. The laser rangefinders 31 at both ends of the vehicle body 1 can monitor the distance between the vehicle and obstacles in front or behind in real time, and issue warning signals through audible and visual alarms 32. This effectively reduces collisions caused by operational errors or blind spots, protecting the safety of on-site personnel, preventing equipment damage, improving production efficiency, and reducing safety hazards. Furthermore, the buffer mechanisms 11 on both sides of the vehicle body 1 serve as mechanical anti-collision mechanisms. When the laser rangefinders 31 fail, the buffer mechanisms 11 can absorb and buffer the resulting impact force, reducing vibration damage to goods, vehicles, and related components, further improving the safety and reliability of the transfer vehicle.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
