Height limiting early warning device for transport vehicle

Abstract

The invention relates to the technical field of transportation, in particular to a height limiting early warning device for a transport vehicle, the device comprises a horizontal slide rail pair, a vertical slide rail pair and an early warning assembly which are mounted at the top of a vehicle head of the transport vehicle and are arranged in parallel along the width direction of the transport vehicle, and the vertical slide rail pair is arranged at the top of the moving end of the horizontal slide rail pair; an early warning assembly is arranged on the side, facing the moving direction of the moving end of the horizontal sliding rail pair, of the moving end of the vertical sliding rail pair. The height of light emitted by the laser generator can be adjusted through the horizontal sliding rail pair and the vertical sliding rail pair, it is guaranteed that the height of the light is higher than the height of the highest point of goods, then the height of the highest point of the goods is determined by directly measuring or calculating the height of the light, and the height of the highest point of the goods can be determined by blocking the upper end of the early warning rod and extruding the trigger switch through the lower end of the early warning rod. The alarm is powered on to give an alarm to remind the driver that the height of the goods is too high, and the driver can avoid in advance or pass after adjusting the goods.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a height limit early warning device for a transportation vehicle. Background technique [0002] When a transport vehicle transports goods, especially those that are not square, it is difficult to measure the specific height of the highest point of the goods, so it is impossible to know in advance whether it can safely pass through a known height limiting device that is not much different from its height, so it cannot be avoided in advance and cannot pass For unknown caves, tunnels and height-limiting devices, before the transport vehicle passes through caves, tunnels and height-limiting devices, especially the difference between the height-limiting dimensions of caves, tunnels and height-limiting devices and the height of the highest point of the cargo When it is not large, the driver needs to stop and observe (there is no other person on the transport vehicle), and multip...

Problems solved by technology

[0002] When the transport vehicle is transporting goods, especially the goods that are not square, it is difficult to measure the specific height of the highest point of the goods, so it is impossible to know in advance whether it can safely pass through known and other places. Height-limiting devices with little difference in height, so it is impossible to avoid the height-limiting devices that cannot be passed in advance. For unknown caves, tunnels and height-limiting devices, it is necessary to transport vehicles before passing through caves, tunnels and height-limiting devices, especially caves and tunnels. When the height limit size of the height limit device is not much different from the height of the highest point of the cargo, the driver needs to stop and observe (there is no other person on the transport vehicle), and multiple operations are required. This operation is also affected by the viewing angle and cannot be advanced It is foreseeable that the goods need to be close to the height limit position to determine whether the transport vehicle can be installed, which is time-consuming and laborious, and a little carelessness may easily lead to scratches and safety accidents

[0003] At present, the existing Chinese patent with the publication number CN211391076U discloses an over-elevation warning mechanism for a vehicle-specific transport vehicle, including a bracket, which is placed on the vehicle The special transport vehicle is fixed on the forward extension platform, the height limit rod is placed on the side of the bracket, the front extension rod is placed on the top of the height limit rod and fixed connected, one end of the spring is hung on the height limit rod, and the other end is hung on the tension wire In the wire loop of the alarm device, the input end of the alarm component is placed on the bracket and fixedly connected, and the display end is located in the cab. Although the device can play an early warning function, the device still has the following defects; 1. The device does not have the ability to measure The height dimension of the highest point of the cargo, so there is still a technical problem that it is difficult to measure the specific height of the highest point of the cargo, so it is impossible to know in advance whether it is safe to pass through a known height-limiting device that is not much different from its height, and it cannot be avoided in advance. 2. Before the device enters the height limit position, if the road surface is downhill and then the road surface is level, it will cause the front end of the front extension rod to be lower than the top of the height limit rod. After the front end of the front extension rod passes, the front end The extension rod is subjected to a downward force, which causes damage to the front extension rod and fails to trigger the normally closed sensor switch; if the road surface is uphill and then the road surface is level, it will cause the front end of the front extension rod to be higher than the top of the height limit rod 1. The height limit device that can barely pass, the front end of the front extension rod cannot pass the height limit position, triggering the normally closed sensor switch, resulting in the need to unload or detour, affecting operating profits
