Abstract
The utility model discloses a hydraulic pressure overload protection device for a concrete mixing transportation vehicle, which comprises a vehicle body. The vehicle body is provided with a tank body,a hydraulic motor and a hydraulic pump. A hydraulic circuit input pipeline of the hydraulic motor is connected with a pressure sensor. The pressure sensor is connected with a control unit through a signal wire. The control unit is connected with an actuating mechanism and can drive the actuating mechanism to work when the tank body is overloaded. The utility model has simple structure, convenientuse and high automation degree, and can effectively avoid the accident potential caused by the overloaded vehicle.
Description
Technical field
The utility model relates to a kind of concrete mixer truck overload protection device, especially relates to a kind of concrete mixer truck hydraulic pressure overload protection device.
Background technology
Along with the development of ready mixed concrete plant, just press for and solve the transportation device of cement concrete from the preparation place to the pouring scene.Truck mixer is exactly this mechanical equipment that is used for long apart from delivering concrete.It is the concrete central mix plant that a kind of uniqueness is installed on goods carrying vehicle or special-purpose carriage chassis, have the dual-use function of delivery and ready-mixed concrete concurrently, can concretely simultaneously it be stirred or stir transporting, to guarantee cement concrete by behind the long-distance transport, still unlikely generation segregation phenomenon.
In recent years, the problem that transfinites in the highway in China transportation was outstanding day by day, had become and had jeopardized people's life security and national wealth safety, influenced the outstanding social concern that social economy coordinates, develops in a healthy way.Concrete mixer truck transfinites also becomes the urban highway killer day by day.Concrete mixer truck in the market all is not with anti-overload, and the user can't grasp vehicle loading weight, has caused certain accident potential.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of concrete mixer truck hydraulic pressure overload protection device is provided, and it is simple in structure, and is easy to use, the degree of automation height can effectively be avoided the accident potential that causes because of overload of vehicle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of concrete mixer truck hydraulic pressure overload protection device, comprise car body, on the described car body tank body is installed, link to each other with described tank body and drive the HM Hydraulic Motor of described tank body axial rotation and be connected with described HM Hydraulic Motor and drive the Hydraulic Pump of HM Hydraulic Motor, it is characterized in that: on the oil circuit input channel of described HM Hydraulic Motor, be connected with pressure sensor, described pressure sensor is connected with control unit by signal wire (SW), is connected with actuating unit on the described control unit and drives described actuating unit action when described tank body overloads.
Described actuating unit is the warning device that can send the sound and light alarm signal, or cuts off the electrical motor fuel path or/and the action element of circuit.
Be connected with the memory cell that is used for storing pressure sensor institute transmission signals on the described control unit.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, easy to use, by on the oil circuit input channel of Hydraulic Pump, connecting pressure sensor, can predict the actual bearer weight of tank body, and when overloading, tank body drives actuating unit action by control unit, to guarantee vehicular transport safety, system deterioration and troublesome situations such as trailer reversing that concrete mixer truck produces because of overload, braking have been avoided; On the other hand, on control unit, connect memory cell, for settlement of accident, traffic police detect, vehicle operation provides accurate data.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises car body, the HM Hydraulic Motor 5 that is used to load concrete tank body, links to each other with tank body and drives the tank body axial rotation is installed on the car body and is connected with HM Hydraulic Motor 5 and drives the Hydraulic Pump 1 of HM Hydraulic Motor 5, on the oil circuit input channel of HM Hydraulic Motor 5, be connected with pressure sensor 4, pressure sensor 4 is connected with control unit 3 by signal wire (SW), is connected with actuating unit 2 on the control unit 3 and drives actuating unit 2 actions when tank body overloads.
Working process of the present utility model is: when concrete mixer truck loads the transportation cement concrete, because the pressure of HM Hydraulic Motor 5 oil circuit input channels can be owing to the tank body load increases, therefore, by measuring HM Hydraulic Motor 5 oil circuit input channel pressure, it is the signal of pressure sensor 4, can learn the actual bearer weight of tank body, pressure sensor 4 arrives control unit 3 with signal by signal wire transmits again, control unit 3 is with institute's transmission signals and overload signal contrast, and driving actuating unit 2 actions when tank body overloads.
In the present embodiment, actuating unit 2 be for sending the warning device of sound and light alarm signal, or cuts off the electrical motor fuel path or/and the action element of circuit, to guarantee vehicle driving safety.Be connected with the memory cell that is used for storing 4 transmission signals of pressure sensor on the control unit 3, like this, memory cell can store the operating mode details of concrete mixer truck, so that provide the information reference data for vehicle operation situation, traffic accident processing are understood by leasing company, the traffic police detects.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
