Detailed Description
The present utility model will be described in further detail with reference to specific embodiments in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limiting the utility model.
Fig. 1 shows a conventional lifting machine, which comprises a vertical column 1 and a supporting arm 2, wherein the supporting arm 2 is arranged on the vertical column 1 and can be lifted along the height direction of the vertical column 1, the supporting arm 2 is used for lifting an automobile, when the supporting arm 2 is positioned below the automobile, an operator operates an operation box 3, and the supporting arm 2 is started to lift so as to drive the automobile to lift.
The utility model provides a safety alarm device for a digital monitoring lifting machine, which monitors whether a safety support frame is placed below the lifting machine in a digital mode, and alarms when the safety support frame is not placed below a lifting arm of the lifting machine after the lifting arm is lifted, so that an operator is reminded to place the safety support frame normally, and the safety of using the lifting machine is improved.
Specifically, the safety alarm device of the digital monitoring lifter comprises a controller, a range finder 5 and an alarm device 7, wherein the range finder 5 is arranged on the lower surface of the supporting arm 2 and is used for measuring the real-time height of the supporting arm 2 from the ground; the alarm device 7 is arranged on the side wall of the top of the upright post 1 and is used for timely giving an alarm according to the instruction of the controller, and the alarm device 7 is arranged on the side wall of the upright post 1 and can not influence the normal lifting operation of the lifting machine.
The controller is respectively connected with the distance meter 5 and the alarm device 7, and judges whether the safety support frame 4 is placed below the supporting arm 2 according to the real-time height change measured by the distance meter 5, and then sends an instruction to the alarm device for alarm. The judgment logic is as follows: when the safety support frame 4 is not placed below the support arm 2, the distance meter 5 measures the distance from the lower surface of the support arm 2 to the ground, the distance is slowly increased along with the rising of the support arm 2 or is kept unchanged along with the rest of the support arm 2, when the safety support frame 4 is placed below the support arm 2, the distance measured by the distance meter 5 is the distance from the lower side of the support arm 2 to the top of the safety support frame 4, the measured value is instantaneously reduced, and the controller can judge that the safety support frame 4 is arranged below the support arm 2.
When the supporting arm 2 is lifted to the set height, the controller does not detect that the safety support frame 4 is placed below the supporting arm 2 within the set time, the controller controls the alarm device 7 to continuously alarm until the controller controls the alarm device 7 to stop alarming after the safety support frame 4 is placed.
The set height and the set time can be set manually through an input device, and the controller carries out logic judgment of whether to alarm or not according to the input value.
Preferably, the distance meter is an infrared distance meter, and the alarm device is a voice audible and visual alarm device.
The safety warning device further comprises a power adapter 6, said power adapter 6 being adapted to supply power to the whole device.
The safety alarm device also comprises network communication equipment, wherein the network communication equipment is used for reporting alarm information in a networking way, preferably an Ethernet interface is embedded in the controller, and the Ethernet interface is used for transmitting data records to an external upper system, so that the safety alarm device has a good system docking function in a later period.
In this example, the height was set to 1.2 meters and the time was set to 30 seconds. As shown in fig. 2, after the lifter starts to operate, the lifter bracket 2 and the upper body of the bracket start to rise, the distance meter 5 monitors the distance between the lower surface of the bracket 2 and the ground in real time, when the real-time distance measured by the distance meter is greater than or equal to 1.2 meters, the controller starts to perform logic judgment on whether to place the safety support frame 4, when the safety support frame 4 is judged not to be placed and the duration exceeds 30s, the alarm device 7 sends out a command to the alarm device 7, the alarm device 7 sends out a voice audible and visual alarm to remind an operator to pay attention until the operator places the safety support frame 4 under the bracket 2, the alarm is stopped, and the operator can perform safety operation.
The device also has additional monitoring functions: if the operation is stopped for a long time, the operation personnel are reminded that the lifting machine needs to be lowered into place, and the lifting machine is not allowed to ascend in a height position for a long time. The controller sets an automatic timing task, acquires the current height of the lifting machine at a shift time point, and carries out voice sound-light alarm to remind operators if the height is higher than 40cm, so as to prevent the situation that the lifting machine has a car on the upper surface from being lowered to a safe height and accidents occur.
The foregoing detailed description describes the basic principles and main features of the present utility model. It should be understood by those skilled in the art that the scope of the present utility model is not limited to the above-described embodiments, and any modifications or substitutions which are not subject to the inventive effort should be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
