Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to an anti-collision protection device for shuttle vehicles. Background Art

[0002] Although traditional shuttle vehicles perform well in improving work efficiency and reducing labor costs, they are subject to collision risks in complex and ever-changing work sites, especially when sharing a workspace with human operators. This may not only cause damage to the equipment, but more seriously, it may threaten the personal safety of the operators.

[0003] Traditional shuttle safety protection measures mostly rely on simple physical barriers or basic infrared sensing technology. These methods either have limited protection range or are susceptible to false alarms due to environmental interference, and cannot accurately and promptly respond to various emergencies. For example, infrared sensors may fail due to environmental factors such as dust and water mist, which greatly reduces the protection function.

[0004] Therefore, it is necessary to provide an anti-collision protection device for a shuttle vehicle to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an anti-collision protection device for a shuttle vehicle, which greatly protects the human body, reduces safety hazards, and improves the safety of the shuttle vehicle during its movement.

[0006] The utility model provides an anti-collision protection device for a shuttle vehicle, comprising:

[0007] A fixing frame, wherein a transmitting and receiving sensor is installed on the back of the fixing frame, two first hooks are fixedly installed on the front of the fixing frame, and a plurality of positioning holes are opened on the front of the fixing frame;

[0008] An elastic sheet is arranged on the front of the fixing frame, and a plurality of bolt assemblies are arranged at both ends of the elastic sheet, and the two ends of the elastic sheet are connected to the positioning holes through the bolt assemblies. A detachable mounting plate is installed on the elastic sheet, and a reflector is fixedly connected to the back of the mounting plate for connecting the photoelectric switch of the shuttle vehicle, and two second hooks are fixedly connected to the back of the elastic sheet;

[0009] Two support springs are arranged between the fixing frame and the elastic sheet, and two ends of the support springs are respectively clamped on the second hook and the first hook.

[0011] Preferably, the two support springs are distributed in a cross shape, and both support springs are located below the transmitting and receiving sensors.

[0012] Preferably, the transmitting and receiving sensors are designed to be tilted, and the positions of the transmitting and receiving sensors correspond one-to-one to the positions of the reflectors.

[0015] Compared with the related art, the anti-collision protection device for a shuttle vehicle provided by the utility model has the following beneficial effects:

[0016] 1. The utility model integrates a fixing frame and an elastic sheet on the side of the shuttle car through an ingeniously designed structure, thereby realizing a high-level safety protection mechanism. When the shuttle car accidentally approaches an obstacle or a pedestrian, the elastic sheet in the device will first contact and undergo elastic deformation.

[0025] The utility model provides an anti-collision protection device for a shuttle vehicle, comprising:

[0026] A fixing frame 1, a transmitting and receiving sensor 6 is installed on the back of the fixing frame 1, two first hooks 3 are fixedly installed on the front of the fixing frame 1, and a plurality of positioning holes 13 are opened on the front of the fixing frame 1;

[0027] The elastic sheet 2 is arranged on the front of the fixing frame 1, and a plurality of bolt assemblies 12 are arranged at both ends of the elastic sheet 2, and the two ends of the elastic sheet 2 are connected to the positioning holes 13 through the bolt assemblies 12. A detachable mounting plate 7 is installed on the elastic sheet 2, and a reflector 8 is fixedly connected to the back of the mounting plate 7 for connecting the photoelectric switch of the shuttle vehicle. Two second hooks 4 are fixedly connected to the back of the elastic sheet 2;

[0028] Two support springs 5 ​​are arranged between the fixing frame 1 and the elastic sheet 2 , and two ends of the support spring 5 are respectively clamped on the second hook 4 and the first hook 3 .

[0029] In the specific implementation process, Figure 1 As shown, the elastic sheet 2 is designed as an arc-shaped structure, and a plurality of movable rollers 11 are arranged on the front of the elastic sheet 2. By setting the plurality of movable rollers 11, when the elastic sheet 2 collides with the human body, the friction between the elastic sheet 2 and the human body can be reduced through the movable rollers 11, thereby preventing the human body and the elastic sheet 2 from being scratched, facilitating the separation of the two, and further improving the protection performance.

[0030] In the specific implementation process, Figure 2 As shown, the two support springs 5 ​​are distributed in a cross shape, and the two support springs 5 ​​are both located below the transmitting and receiving sensors 6. Through their design, the support springs 5 ​​can elastically support the elastic sheet 2, supplement the elastic potential energy of the elastic sheet 2, and ensure that the elastic sheet 2 can recover its later deformation after being bumped or squeezed, while also increasing the elastic protective effect of the elastic sheet 2.

[0031] In the specific implementation process, Figure 2 As shown, the transmitting and receiving sensor 6 is tilted, and the position of the transmitting and receiving sensor 6 corresponds to the position of the reflector 8. Through its design, the transmitting and receiving sensor 6 can correspond to the reflector 8, preventing the supporting spring 5 from blocking the correspondence between the transmitting and receiving sensor 6 and the reflector 8.

[0032] In the specific implementation process, Figure 3 As shown, a slot 10 is provided at the bottom of the mounting plate 7, and the mounting plate 7 is connected to the elastic sheet 2 through the slot 10, and the inner wall of the slot 10 is coated with a rubber layer. The rubber layer can increase the friction between the slot 10 in the mounting plate 7 and the elastic sheet 2 to prevent the mounting plate 7 from loosening.

[0033] In the specific implementation process, Figure 3 As shown, a fastening screw 9 is threadedly connected to the back of the mounting plate 7, and the front end of the fastening screw 9 passes through the slot 10. After adjusting the position of the mounting plate 7, the mounting plate 7 can be positioned by tightening the fastening screw 9 and squeezing the elastic sheet 2, so as to facilitate the positioning of the reflector 8 at any time after adjusting it.

[0034] The working principle of the anti-collision protection device for a shuttle vehicle provided by the utility model is as follows: first, the device is installed on one side of the shuttle vehicle in the direction of travel by means of a fixing frame 1 in conjunction with screws. The light emitted from the transmitting and receiving sensor 6 by the photoelectric switch on the shuttle vehicle is reflected back to the transmitting and receiving sensor 6 through the reflector 8 for reception. When the shuttle vehicle touches an object or a human body during travel, the elastic sheet 2 is firstly elastically deformed by the touch, which plays a buffering role. At the same time, the elastic sheet 2 is deformed during the deformation process, so that the reflector 8 is also displaced. Then the light emitted from the transmitting and receiving sensor 6 cannot pass through the reflector 8 to return to the receiver of the transmitting and receiving sensor 6. Then the photoelectric switch generates a detection switch signal to control the shuttle vehicle to stop moving. After the person walks away or moves away the touched object, the elastic sheet 2 returns to its original state, and the transmitting and receiving sensor 6 can receive the signal again, so that the shuttle vehicle can move normally.

[0035] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
