Abstract
The utility model discloses a hydraulic pressure overload protection device of a concrete mixing and transporting car. A pressure sensor is arranged on a hydraulic pipeline communicated with a hydraulic motor, and the pressure sensor is connected with a programmable logic controller (PLC) by a signal line. In the overload protection device, the pressure sensor is arranged on the hydraulic pipeline communicated with the hydraulic motor, and the pressure change at an input end of the hydraulic motor can be measured by the pressure sensor so as to learn the loading capacity of the concrete mixing and transporting car, therefore, the loading information of the concrete mixing and transporting car can be provided to a user, and, the phenomena of the concrete mixing and transporting car that car systems such as an operating system, a braking system and the like are deteriorated, faults can be caused easily, and the like due to overloading can be avoided; and the overload protection device has the advantages that the design is reasonable, the structure is simple, the efficiency is high, the automatic degree is high, the production cost is low, and the generality is good.
Description
Technical field
The utility model belongs to the facilities for transport and communication technical field, is specifically related to a kind of concrete mixer truck hydraulic pressure overload protection device.
Background technology
Truck mixer is a kind of vehicle that can specialize in the conveying of commerical ready-mixed concrete.Along with the development of ready mixed concrete plant, press for the transportation device of cement concrete from the preparation place to the pouring scene.Truck mixer is exactly to be specifically designed to long mechanical equipment apart from delivering concrete, it is on goods carrying vehicle or special-purpose carriage chassis concrete central mix plant to be installed, have the dual-use function of delivery and ready-mixed concrete concurrently, can concretely simultaneously it be stirred or stir transporting, to guarantee that cement concrete by behind the long-distance transport, does not produce segregation phenomenon.
In the last few years, the range of use of concrete mixer truck was enlarging day by day.Along with the develop rapidly of China's urban construction and the raising of the level of urbanization, China's concreting machinery has obtained fast development.Along with the demand of ready-mixed concrete is increasing, domestic communication in recent years, municipal are greatly developed in addition. and road and bridge facility situation is greatly improved, and strengthening the infrastructure investment dynamics, increase the demand of ready-mixed concrete thus on the one hand, created favourable transportation condition for mixermobile transports commerical ready-mixed concrete on the other hand.
In recent years, the problem that transfinites in the highway in China transportation was outstanding day by day, had become and 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 overload protection device, and the user can't grasp vehicle loading weight, therefore, is badly in need of a kind of device that can point out user's overload of vehicle of development.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming that concrete mixer truck does not have overload protection device, for concrete mixer truck provides a kind of reasonable in design, simple in structure, productive costs is low, commonality is good concrete mixer truck hydraulic pressure overload protection device.
Solving the problems of the technologies described above the technical scheme that is adopted is: be provided with pressure sensor with the conduit under fluid pressure of HM Hydraulic Motor UNICOM, pressure sensor links by signal wire (SW) and Programmable Logic Controller.
The utility model by with conduit under fluid pressure that HM Hydraulic Motor connects on pressure sensor is set, pressure by sensor measurement HM Hydraulic Motor input end changes, thereby learn the load carrying ability of concrete mixer truck, the weight information of concrete mixer truck is provided for the user, avoid the generation of phenomenons such as system deterioration, easy break-down such as trailer reversing that concrete mixer truck produces because of overload, braking, had advantage reasonable in design, simple in structure, that efficient is high, degree of automation is high, productive costs is low, commonality is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and each embodiment the utility model is further described, but the utility model is not limited to these embodiment.
Embodiment 1
In Fig. 1, the concrete mixer truck hydraulic pressure overload protection device of present embodiment is made of Programmable Logic Controller 1, signal wire (SW) 2, pressure sensor 3 connections.
HM Hydraulic Motor 4 links by conduit under fluid pressure and Hydraulic Pump 5, HM Hydraulic Motor 4 provides power for the concrete central mix plant of concrete mixer truck, on the conduit under fluid pressure of Hydraulic Pump 5 and HM Hydraulic Motor 4 UNICOMs, connect pressure sensor 3 is installed by connector, pressure sensor 3 is used to measure the pressure variation of HM Hydraulic Motor 4 input ends, when concrete mixer truck loads cement concrete, the pressure of HM Hydraulic Motor 4 input ends can increase owing to the increase of load, promptly knows the load carrying ability of concrete mixer truck by the variation of measuring HM Hydraulic Motor 4 input end pressure with pressure sensor 3.Pressure sensor 3 links to each other with Programmable Logic Controller 1 by signal wire (SW) 2, the model of Programmable Logic Controller 1 is CP1H-XA40DT-D, the commodity of Programmable Logic Controller 1 for selling on the market, pressure sensor 3 converts the pressure signal that receives to electric signal and converts digital signal to and outputs to Programmable Logic Controller 1 by signal wire (SW) 2, Programmable Logic Controller 1 compares signal of receiving and the overload signal that is stored in advance in the Programmable Logic Controller 1, Programmable Logic Controller 1 can link to each other with combined aural and visual alarm by signal wire (SW), or link to each other by the switch of signal wire (SW) with engine fuel oil circuit or circuit, when Programmable Logic Controller 1 detects the load carrying ability generation overload of concrete mixer truck, Programmable Logic Controller 1 can send signal conditioning overload incident, as the switch of opening combined aural and visual alarm sends the sound and light alarm signal, or the switch combustion cutoff fuel path of kill engine fuel path or circuit or circuit etc.Programmable Logic Controller 1 stored unit further stores the operating mode details, understands the vehicle operation situation for user, driver, for traffic accident processing, traffic police's detection provide the information reference data.
The utility model adopts setting pressure sensor 3 on the conduit under fluid pressure of HM Hydraulic Motor 4 input ends, change the measurement that realizes the concrete mixer truck load carrying ability by the pressure of measuring HM Hydraulic Motor 4 input ends, avoid phenomenons such as system deterioration, easy break-down such as trailer reversing that concrete mixer truck produces because of overload, braking to take place, the utlity model has advantages such as reasonable in design, simple in structure, that efficient is high, degree of automation is high, productive costs is low, commonality is good.
