Abstract
The utility model relates to an automobile hopper unloading alarm device.A middle relay coil (2) is connected with a proximity switch contact (3) in series; auxiliary contact (4) of intermediate relay establishes ties with audible-visual annunciator (5), and these two sets of series circuit are parallelly connected and all connect in parallel with car power (1), and proximity switch (7) are located mounting bracket (9), and mounting bracket (9) all install on car (6) with hopper (8). The utility model has simple structure, low cost and good economical efficiency, and only needs to be provided with the photoelectric inductive switch to be matched with the intermediate relay for use. The combination of sound and flashing light can improve the warning effect, especially at night. Can be used for lift trucks, cranes and other vehicle types, and has the advantages of wide application range and the like. The utility model can only alarm when the hopper is lowered to the original position, thus improving the warning effect.
Description
The technical field is as follows:
the utility model relates to an automobile hopper unloading alarm device.
Background art:
when the automobile dump truck automatically unloads on the truck bed, the truck hopper is jacked up, and at the moment, a driver still can drive the automobile to continue to walk by operation, so that personal injury and equipment damage are caused by the risks of collision height limiting measures, various pipelines, high-voltage cables and the like. Therefore, it is necessary to develop a device for sounding and flashing an alarm when the hopper of the dump truck is lifted, so as to remind a driver of the position of the hopper, pay attention to safety, and the alarm disappears when the hopper is restored to the original position.
The utility model content is as follows:
the utility model aims to provide an automobile hopper unloading alarm device which is simple in structure, low in manufacturing cost and good in economical efficiency, and only needs to be provided with a photoelectric sensing switch to be matched with an intermediate relay for use.
The technical scheme of the utility model is as follows: an automobile hopper unloading alarm device is characterized in that an intermediate relay coil (2) is connected with a proximity switch contact (3) in series; auxiliary contact (4) of intermediate relay establishes ties with audible-visual annunciator (5), and these two sets of series circuit are parallelly connected and all connect in parallel with car power (1), and proximity switch (7) are located mounting bracket (9), and mounting bracket (9) all install on car (6) with hopper (8).
The auxiliary contact (4) of the intermediate relay is an auxiliary contact on the coil (2) of the intermediate relay, and the contact (3) of the proximity switch is a contact on the proximity switch (7).
The working principle of the utility model is as follows:
when the automobile unloads and the hopper rises, the proximity switch contact (3) is closed, the intermediate relay coil (2) is electrified, the intermediate relay auxiliary contact (4) is closed, the audible and visual alarm (5) is electrified, and the audible and visual prompt begins to be sent out by the alarm. When the automobile finishes unloading, after the hopper is lowered to the original position, the proximity switch contact (3) is opened, the intermediate relay coil (2) loses power, meanwhile, the intermediate relay auxiliary contact (4) is opened, the audible and visual alarm (5) loses power, and the audible and visual alarm disappears.
The utility model has the technical effects that:
the structure of the utility model detects the position of the hopper through the proximity switch, and has the following advantages:
1. the structure is simple, only the photoelectric sensing switch is required to be installed to be matched with the intermediate relay for use, the manufacturing cost is low, and the economical efficiency is good.
2. The combination of sound and flashing light can improve the warning effect, especially at night.
3. The utility model can be used for lift trucks, cranes and other vehicle types, and has the advantages of wide application range and the like.
4. The utility model can only alarm when the hopper is lowered to the original position, thus improving the warning effect.
