Abstract
The invention discloses a forklift hydraulic cylinder detector and relates to the technical field of hydraulic cylinder displacement detection and display. The forklift hydraulic cylinder detector comprises a flow meter, a temperature sensor, a single chip microcomputer, a liquid level sensor, a display module, an alarming module and a power supply module, wherein the flow meter is mounted on a hydraulic oil pipe connected with a hydraulic cylinder and is used for detecting the flow of hydraulic oil flowing into the hydraulic cylinder in real time; the temperature sensor is mounted on the outer cylinder wall of the hydraulic cylinder and is used for detecting the temperature of the hydraulic cylinder; the single chip microcomputer is connected with the flow meter and is used for receiving information of the flow meter and analyzing data; the liquid level sensor is mounted in the hydraulic cylinder and is used for detecting the oil level of the hydraulic cylinder; the single chip microcomputer is respectively connected with the flow meter, the temperature sensor and the liquid level sensor and is applied to data processing; the display module is connected with the single chip microcomputer and is used for displaying the displacement, the temperature and the liquid level of the hydraulic cylinder; the alarming module is connected with the single chip microcomputer; the power supply module supplies power to all the modules. The forklift hydraulic cylinder detector has the advantages that the detector can be directly mounted, the conventional mechanical structure of a forklift is not changed, the normal use of the forklift is not impacted, and the breakage situation of a hydraulic rod in the hydraulic cylinder is reduced.
Description
Technical field
The present invention relates to oil hydraulic cylinder displacement monitoring and Display Technique field, specifically a kind of forklift oil hydraulic cylinder detection device, is applicable to all kinds of oil hydraulic cylinder model.
Background technique
Along with improving constantly of industrial automation level, the ratio of forklift shared by engineering machinery constantly increases.Forklift in the market does not possess the function of display oil hydraulic cylinder present position in real time, can only lean on the experience of driver to operate machines.But often because driver does not note the concrete condition of front necromancer stone, thus excavate by force, cause hydraulic rod to rupture.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of forklift oil hydraulic cylinder detection device; In time oil hydraulic cylinder misalignment can be fed back to driver, thus judge timely, reduce the situations such as forklift hydraulic rod fracture and occur.
The present invention realizes with following scheme: a kind of forklift oil hydraulic cylinder detection device, comprising on the hydraulic oil pipe that is arranged on and is connected with oil hydraulic cylinder for detecting the flowmeter flowing into hydraulic fluid flow rate in oil hydraulic cylinder in real time, being arranged on oil hydraulic cylinder on outside casing wall for the temperature transducer that detects oil hydraulic cylinder temperature for being connected with flowmeter for accepting flowmeter information and analyzing the single-chip microcomputer of data; Be arranged on oil hydraulic cylinder inner for detecting the liquid level sensor of oil hydraulic cylinder oil level; Being connected with flowmeter, temperature transducer and liquid level sensor Dare single-chip microcomputer respectively and being used for the single-chip microcomputer of data processing, being connected the display modular for showing oil hydraulic cylinder displacement, temperature and liquid level with single-chip microcomputer; The alarm module for reporting to the police is connected with single-chip microcomputer; To the power module that above-mentioned modules is powered.
The invention has the beneficial effects as follows: level of integration is high, volume is little, and cost is low, directly installs the existing machinery mechanism that need not change forklift, does not affect the normal use of forklift, decreases the situation of hydraulic rod fracture in oil hydraulic cylinder.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described in more detail.
Fig. 1 is principle of the invention block diagram.
In figure: 1, oil hydraulic cylinder; 2, hydraulic oil pipe, 3, flowmeter, 4, guard shield, 5, liquid level sensor, 6, temperature transducer.
Embodiment
As shown in Figure 1, for detecting the flowmeter 3 flowing into hydraulic fluid flow rate in oil hydraulic cylinder in real time on the hydraulic oil pipe 2 that a kind of forklift oil hydraulic cylinder detection device has to be arranged on to be connected with oil hydraulic cylinder 1, to be arranged on oil hydraulic cylinder on outside casing wall for the temperature transducer 6 that detects oil hydraulic cylinder temperature for being connected for accepting flowmeter information and analyzing the single-chip microcomputer of data with flowmeter; Be arranged on oil hydraulic cylinder inner for detecting the liquid level sensor 5 of oil hydraulic cylinder oil level; Being connected with flowmeter 3, temperature transducer 6 and liquid level sensor 5 Dare single-chip microcomputer respectively and being used for the single-chip microcomputer of data processing, being connected the display modular for showing oil hydraulic cylinder displacement, temperature and liquid level with single-chip microcomputer; The alarm module for reporting to the police is connected with single-chip microcomputer; To the power module that above-mentioned modules is powered.
In order to prevent temperature transducer from wearing and tearing, the casing wall of oil hydraulic cylinder is installed the guard shield 4 of the described temperature transducer of a protection.Wherein flowmeter 3 is for measuring the flow flowing into hydraulic oil oil hydraulic cylinder from hydraulic tube; When oil hydraulic cylinder exceeds certain limit or temperature is too high or liquid level is too low, give the alarm to point out driver careful operation.Flowmeter is arranged on the hydraulic oil pipe 2 that is connected with oil hydraulic cylinder 1, does not affect the normal use of forklift.
Working procedure: be arranged on the hydraulic oil pipe be connected with oil hydraulic cylinder by the flowmeter in this device, display modular is arranged in operator cabin.Once hydraulic system is started working, driver just can see hydraulic displacement, can judge timely, thus reduces the situation of hydraulic rod fracture.Meanwhile, the information that temperature transducer and liquid level sensor are detected is sent on display modular and shows.
