In general, logistics transportation is an important link in the modern logistics system. It provides a strong guarantee for the production and sales of enterprises through efficient, accurate and safe transportation services, and also promotes economic development and the process of globalization.

[0003] Among them, in the process of logistics transportation, using transport vehicles to transport goods is one of the main means of logistics transportation. In the process of using transport vehicles to transport goods, when the transport vehicles enter the unloading area to unload the goods, due to the generally large size of the transport vehicles, there are many dead angles and blind spots in the unloading process of the transport vehicles, especially at night when the lighting is insufficient, the transport vehicles cannot be easily parked in the unloading area, and the transport vehicles are prone to scratches, thereby increasing the safety risk of unloading the transport vehicles. Utility Model Content

[0004] The purpose of the utility model is to provide a safety positioning device for a transport vehicle to solve the problem raised in the above-mentioned background technology that in the process of using a transport vehicle to transport goods, when the transport vehicle enters the unloading area to unload the goods, due to the generally large size of the transport vehicle, there are many dead angles and blind spots in the process of unloading the goods, especially at night when the ambient lighting is insufficient, the transport vehicle cannot be easily parked in the unloading area, and the transport vehicle is prone to scratches, thereby increasing the safety risk of unloading the transport vehicle.

[0005] To achieve the above purpose, the utility model provides the following technical solution: comprising an unloading area and an installation shell, wherein a pre-buried installation groove is provided on the outer periphery of the rear side of the unloading area, an installation outer edge is provided on the upper end of the installation shell, and installation holes are provided through the four corners of the installation outer edge;

[0006] Limiting tubes are fixedly installed at the four corners of the bottom of the installation shell, the inner wall of the upper end of the limiting tube is movably connected to the limiting column, the upper top of the limiting column is fixedly installed with an installation inner shell, the four corners of the bottom of the installation inner shell are fixedly installed with supporting springs, the inner side of the inner bottom of the installation inner shell respectively supports and fixes an infrared detection type proximity sensor and a warning light, the upper end of the installation inner shell is fixedly installed with an arc-shaped protective top cover, the inner side wall of the arc-shaped protective top cover is penetrated and fixedly installed with a transparent cover, and the outer inner wall of the arc-shaped protective top cover is fixedly installed with a speaker for sound prompting the truck driver.

[0007] Preferably, a drainage groove is provided through the bottom of the embedded installation groove, and the drainage groove is connected to an external sewer.

[0008] Preferably, the installation shell is movably connected to the inner wall of the embedded installation groove, and the installation holes are symmetrically distributed at the four corners of the installation outer edge.

[0009] Preferably, a first wiring hole and a drainage hole are respectively formed through the middle and both sides of the inner bottom of the installation shell.

[0010] Preferably, the limiting tubes are symmetrically distributed at the four corners of the bottom inner of the mounting shell, the outer peripheral surface of the mounting inner shell is movably connected to the inner wall of the upper end of the mounting shell, and the lower bottom end of the support spring is fixedly installed at the four corners of the bottom of the mounting inner shell.

[0011] Preferably, a second wiring hole is provided through the outer side of the inner bottom of the mounting inner shell, and the warning light is in a normally on state.

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

[0014] 1. The utility model can guide the truck driver with light positioning by the prompt light emitted by the prompt light penetrating through the transparent cover. When the truck is unloading in the unloading area, if there is a position deviation, the truck deviation will cause the rear of the truck to approach the arc-shaped protective top cover. When the rear of the truck is close to the arc-shaped protective top cover, the infrared detection proximity sensor will sense the approach of the truck. When the infrared detection proximity sensor senses the approach of the truck, the controller can control the speaker to turn on for voice prompts, thereby achieving the light positioning guidance of the truck. When the truck has a position deviation, a voice safety reminder will be given to avoid the truck from being scratched or collided when unloading.

[0015] 2. The utility model also can prevent the arc-shaped protective top cover from being damaged by the pressure of the truck tire when the truck has position deviation and causes the truck tire to accidentally press on the arc-shaped protective top cover. The arc-shaped protective top cover will drive the installation inner shell to move downward and shrink along the inner wall of the upper end of the installation outer shell. When the arc-shaped protective top cover shrinks downward, the arc-shaped protective top cover can be avoided. At the same time, when the installation inner shell moves downward and shrinks, it will push the limit column to move linearly downward along the inner wall of the upper end of the limit tube while pushing the compression support spring. When the support spring is pushed and compressed, the elastic potential energy generated by the compression deformation of the support spring will automatically push the installation inner shell to move upward and reset. When the truck tire no longer presses the arc-shaped protective top cover, the arc-shaped protective top cover and the installation inner shell will automatically move upward and reset under the push of the elastic potential energy of the support spring, thereby achieving the effect of automatically moving and resetting the arc-shaped protective top cover while avoiding being damaged by the pressure of the truck tire.

[0023] The middle part and both sides of the inner bottom of the installation shell 2 are respectively penetrated with a first wiring hole 7 and a drainage hole 8, the four corners of the inner bottom of the installation shell 2 are fixedly installed with a limiting tube 9, and the limiting tubes 9 are symmetrically distributed at the four corners of the inner bottom of the installation shell 2, the inner wall of the upper end of the limiting tube 9 fits and is movably connected with a limiting column 10, the top of the limiting column 10 is fixedly installed with an installation inner shell 11, and the outer circumferential surface of the installation inner shell 11 fits and is movably connected to the inner wall of the upper end of the installation shell 2, the four corners of the bottom of the installation inner shell 11 are fixedly installed with a supporting spring 12, and the lower bottom end of the supporting spring 12 is fixedly installed at the four corners of the bottom of the installation inner shell 11, so that the installation inner shell 11 is elastically supported by the supporting spring 12 in cooperation with the limiting tube 9 and the limiting column 10, the outer side of the inner bottom of the installation inner shell 11 is penetrated with a second wiring hole 13, and the inner side of the inner bottom of the installation inner shell 11 is respectively supported and fixedly installed with a red An external detection proximity sensor 14 and a warning light 15, and the warning light 15 is always on, so that the driver is informed of the position of the unloading area 1 by the warning light 15. The infrared detection proximity sensor 14 is composed of an infrared transmitter and a receiver. When a truck approaches, a part of the infrared rays will be reflected. After the receiver receives these reflected infrared rays, the proximity of the truck can be determined. An arc-shaped protective top cover 16 is fixedly installed on the upper end of the inner shell 11, and a transparent cover 17 is fixedly installed through the inner wall of the arc-shaped protective top cover 16. A speaker 18 for sound prompting the truck driver is fixedly installed on the outer inner wall of the arc-shaped protective top cover 16, and the infrared detection proximity sensor 14 is electrically connected to the speaker 18 through a wire and a controller, so that the infrared detection proximity sensor 14 cooperates with the controller to control the opening and closing of the speaker 18.

[0024] Working principle: When in use, when a truck enters the unloading area 1 at night when there is insufficient light, the utility model can provide light positioning guidance for the truck driver through the prompt light emitted by the prompt light 15 passing through the transparent cover 17. When the truck is unloading in the unloading area 1, if there is a position deviation, the truck deviation will cause the rear end of the truck to approach the arc-shaped protective top cover 16. When the rear end of the truck approaches the arc-shaped protective top cover 16, the infrared detection proximity sensor 14 will sense the approach of the truck. When the infrared detection proximity sensor 14 senses the approach of the truck, the controller can control the speaker 18 to turn on for a sound prompt, thereby achieving light positioning guidance for the truck. When the truck has a position deviation, a sound safety reminder will be given to avoid scratches and collisions when the truck is unloading.

[0025] At the same time, when the truck has a position deviation and causes the truck tire to accidentally press on the curved protective top cover 16, the curved protective top cover 16 will drive the installation inner shell 11 to move downward and shrink along the inner wall of the upper end of the installation outer shell 2. When the curved protective top cover 16 shrinks downward, the situation in which the curved protective top cover 16 is damaged by the pressing of the truck tire can be avoided. At the same time, when the installation inner shell 11 moves downward and shrinks, it will push the limit column 10 to move linearly downward along the inner wall of the upper end of the limit tube 9 while pushing the compression support spring 12. When the support spring 12 is pushed and compressed, the elastic potential energy generated by the compression deformation of the support spring 12 will automatically push the installation inner shell 11 to move upward and reset, so that when the truck tire no longer presses the curved protective top cover 16, the curved protective top cover 16 and the installation inner shell 11 will automatically move upward and reset under the push of the elastic potential energy of the support spring 12, thereby achieving the effect of automatically moving and resetting the curved protective top cover 16 while avoiding being pressed and damaged by the truck tire.
