Description

Tip lorry with alarm device

Technical Field

The utility model relates to the technical field of transportation equipment, in particular to a dump truck with an alarm device.

Background

In construction sites or mining areas of mines, a large number of dump trucks are often used to transport and load and unload materials. A dump truck is a special vehicle with a tiltable hopper and used for short-distance material conveying. A "bucket" like container is mounted on the body of the dump truck as a bucket, the front end of which can be raised to facilitate unloading. The dump truck is suitable for short-distance transportation of various bulk materials such as sand, earthwork, coal, ore and the like, has strong power and usually has a mechanical return function. In the practical application process, the front end of the hopper is lifted for unloading, so that materials in the hopper fall from the rear end, but the hopper is forgotten to fall back to the initial position after the driver finishes unloading, and the hopper directly drives away from an unloading site. In this case, a car hopper whose front end is inclined upward is likely to cause a safety accident, and road administration facilities such as a height limit pole on a road are also likely to be damaged by the car hopper.

SUMMERY OF THE UTILITY MODEL

The present invention is made to solve the above-mentioned technical problems, and an object of the present invention is to provide a dump truck having an alarm device, wherein when the front end of the truck hopper rises, an alarm message is issued, and the alarm message is stopped after the truck hopper falls to an initial position, so as to ensure that a driver can drive the truck in a safe condition.

In order to achieve the above object, the present invention provides a dump truck having an alarm device, comprising: the device comprises a vehicle body, a hopper and an alarm device; the rear end of the car hopper is hinged to the rear end of the car body, and the car body is provided with a telescopic device for driving the front end of the car hopper to lift; the alarm device comprises a power supply, a travel switch and an alarm, which form a loop, wherein the travel switch is arranged between the hopper and the vehicle body; when the car hopper is lifted, the contact of the travel switch is closed, and the warning indicator sends warning information; when the car hopper falls down, the contacts of the travel switch are separated, and the warning indicator stops sending warning information.

Preferably, the alarm comprises an alarm light and/or an electric bell.

Preferably, the alarm is two alarm lamps and an electric bell which are arranged in parallel.

Preferably, the power supply is an on-board direct current 24V storage battery.

Preferably, the electric bell is a 24V automobile reversing buzzer.

Preferably, the warning lamp is a 24V automobile bulb.

Preferably, the travel switch is a ball rocker type travel switch.

Preferably, the travel switch is fixedly mounted on the vehicle body, and a swing rod of the travel switch faces the hopper.

Preferably, the warning indicator is disposed in a cab of the dump truck.

As can be seen from the above description and practices, the dump truck with alarm device described in the present invention is provided with an alarm device including a power source, a travel switch and an alarm, wherein the travel switch is provided between the body and the hopper of the dump truck for monitoring the state of the hopper rising or falling. When the car hopper is lifted, the contact of the travel switch is closed, and accordingly the warning device is connected with the power supply and sends warning information; when the car hopper falls down, the contacts of the travel switch are separated, and accordingly, the warning indicator is disconnected from the power supply and stops sending warning information.

Fig. 1 is a schematic structural view of a dump truck with an alarm device according to an embodiment of the present invention, showing an external structure of the dump truck. Fig. 2 is a schematic circuit diagram of an alarm device according to an embodiment of the present invention.

Referring to fig. 1 and 2, a dump truck with an alarm device mainly includes a truck body 1, a hopper 2, and an alarm device. Wherein the vehicle body 1 is an existing carrier, and the vehicle hopper 2 is a container in a shape of a 'hopper'. The hopper 2 is arranged on the vehicle body 1, and the rear end of the hopper 2 is hinged with the rear end of the vehicle body 1. The vehicle body 1 is provided with a telescopic device, such as a hydraulic telescopic rod, for driving the front end of the hopper 2 to ascend and descend. When the telescopic device extends, the front end of the car hopper 2 is driven to rise, and materials in the car hopper 2 can be discharged from the car hopper; when the driving device is contracted, the front end of the driving hopper 2 falls down, and the hopper 2 is restored to the initial state, at this time, the transportation operation can be carried out.

The alarm device comprises a power supply, a travel switch and an alarm which form a loop. Wherein the travel switch is provided between the vehicle body 1 and the hopper 2, and the position of the travel switch is set to: when the car hopper 2 rises, the contact of the travel switch is closed, and accordingly the warning device is connected with the power supply and sends warning information; when the car hopper 2 falls down, the contacts of the travel switch are separated, and accordingly, the alarm is disconnected from the power supply and stops working.

In this embodiment, as shown in fig. 2, the alarm device is composed of a power source 3, a travel switch 4, a warning lamp 5 and an electric bell 6. Specifically, the power supply 3 may be an on-board dc 24V battery, which is a common device on the vehicle, in other words, the travel switch and the alarm in the embodiment may be directly connected to the existing circuit in the vehicle. The alarm device is convenient to set, and meanwhile, the cost can be saved.

In the embodiment, the alarm adopts the alarm lamp 5 and the electric bell 6 which are connected in parallel into the circuit of the alarm device, when the travel switch 4 is closed, the alarm lamp 5 is turned on, and the electric bell 6 makes a sound to remind a driver that the car hopper 2 is in a rising state. Specifically, the warning light 5 can be a 24V automobile bulb, and the electric bell 6 can be a 24V automobile reversing buzzer, which is a common device for automobile vehicles, is low in price and can be adapted to a vehicle-mounted storage battery.

In other embodiments, only the warning light 5 or the electric bell 6 may be provided as a warning indicator, and the driver may be reminded that the car body 2 is in the lifted state. In addition, the warning lamp and the electric bell 6 can be arranged in the cab, so that a driver can know the state of the hopper 2 when driving the vehicle.

In addition, in this embodiment, the travel switch 4 is a ball rocker type travel switch. The travel switch is fixedly arranged on the vehicle body 1, and a swing rod on the travel switch faces one side of the vehicle hopper 2. When the car hopper 2 rises, the swing rod rises upwards under the pushing of a spring in the travel switch 4, at the moment, a contact in the travel switch 4 is closed, so that a circuit of the alarm device is closed, and the alarm sends out alarm information; when the car hopper 2 falls down and resets, the swing rod falls back downwards under the pushing of the car hopper 2, at the moment, the contacts in the travel switch 4 are separated, the circuit of the alarm device is disconnected, and the alarm stops sending out alarm information. The travel switch 4 can accurately realize the on-off of the alarm device, thereby reminding a driver of the current rising or resetting state of the car hopper 2 and ensuring the safety and reliability of the material transportation process.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
