Description

Technical Field

[0001] The utility model belongs to the technical field of loading and unloading for flow meter calibration, and particularly relates to a loading and unloading device for flow meter calibration. Background Art

[0002] A flow meter is an instrument used to measure the flow of fluids (such as water, gas, oil, etc.) in a pipeline or open channel. It can indicate the instantaneous flow rate of the measured fluid and / or the total flow rate within a specific time interval. Flow meters are widely used in industrial production, environmental monitoring, energy management and other fields to ensure the accuracy of process control and the effective use of resources. The flow meter calibration loading and unloading device is a device designed for the calibration and maintenance of flow meters. It allows the flow meter to be safely and efficiently moved from the site of use to the calibration device for accuracy verification or calibration, and then returned to use.

[0003] The existing flow meter calibration loading and unloading device loads and unloads the flow meter through a mobile cart, but its fixing mechanism cannot be adjusted in size to accommodate flow meters of different sizes. A fixing mechanism of a fixed size can only be applied to flow meters of a specific size, which means that the same device cannot serve multiple models of flow meters, reducing the versatility and economy of the equipment. Utility Model Content

[0004] In view of this, the utility model aims to provide a loading and unloading device for flow meter calibration, which can adjust the distance between the arc-shaped fixing plates on both sides to adapt to the loading and unloading of flow meters of different sizes, significantly improve the use range and flexibility of the equipment, and facilitate personnel to use.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a loading and unloading device for flow meter calibration, including a bottom plate, four electric push rods are arranged on the upper end of the bottom plate, a lifting plate is arranged between the telescopic ends of the four electric push rods, a push handle is arranged on the upper end of the bottom plate, a clamping and fixing loading and unloading mechanism is arranged inside the lifting plate, a supporting and stabilizing mechanism is arranged on the front and rear sides of the bottom plate, the clamping and fixing loading and unloading mechanism includes two arc-shaped fixed plates slidably arranged inside the lifting plate, two rotating seats are arranged at the lower ends of the two arc-shaped fixed plates, a connecting frame is rotatably arranged inside the four rotating seats, and the lower end of the lifting plate Two rotating frames are slidingly arranged, and two adjacent front and rear connecting frames are respectively rotatably connected to the inside of one rotating frame, and two rectangular plates corresponding to the left and right positions are arranged at the lower end of the lifting plate, and screw rods are rotatably arranged inside the two rectangular plates, and the thread directions of the two screw rods are opposite, and the two rotating frames are respectively threadedly connected to the adjacent screw rods, and an arc plate is also arranged at the upper end of the lifting plate, and an electric drive unit is arranged at the lower end of the lifting plate to drive the screw rod to rotate, and the electric drive unit includes a double-axis motor arranged at the lower end of the lifting plate, and the output shafts on the left and right sides of the double-axis motor are respectively connected to the relative inner ends of the two screw rods through couplings.

[0007] As a further improvement of the utility model, flexible pads are bonded to the inner curved surfaces of the curved fixing plates.

[0008] As a further improvement of the utility model, casters are rotatably provided at the four corners of the lower end of the base plate.

[0009] As a further improvement of the utility model, a control panel is arranged at the upper end of the push handle, and the dual-axis motor, the electric push rod 1 and the electric push rod 2 are all electrically connected to the control panel.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] First, the flowmeter is hoisted onto the arc plate through external hoisting equipment so that it is located between the two arc-shaped fixed plates. Then, the control panel is controlled to open the double-axis motor, and the output shaft drives the screws on both sides to rotate. Since the screw threads on both sides are in opposite directions, the rotating frame moves away from each other, and its internal connecting frame rotates and contracts, driving the arc-shaped fixed plates on the rotating seat to move closer to each other to clamp the front and back sides of the dose meter. Then, the loading and unloading device is pushed to a suitable installation position by the push handle and the caster at the lower end. Then, the control panel is controlled to open the electric push rod 1, which can adjust the height of the meter on the lifting plate to correspond to the position of the installation mechanism, and install the flowmeter through bolts. The control panel is controlled to open the electric push rod 1 to make the arc plate on the lifting plate contact with the flowmeter. Then, the control panel is controlled to open the double-axis motor to make the arc-shaped fixed plates on both sides move closer to each other to fix the flowmeter. Then, the bolts are removed to disassemble the flowmeter. The spacing between the arc-shaped fixed plates on both sides can be adjusted to accommodate the loading and unloading of flowmeters of different sizes, which significantly improves the use range and flexibility of the equipment and is convenient for personnel to use.

[0012] Secondly, the control panel is used to control the opening of the electric push rod 2, and the telescopic end drives the support plate to move downward and contact the ground, thereby expanding the contact area between the loading and unloading device and the ground, making the operation of the loading and unloading device more stable.

[0013] Thirdly, the flow meter can be protected from damage by the flexible pad on the inner curved surface of the curved fixing plate.

[0014] Fourthly, the control panel makes it easy for personnel to control the electrical components on the loading and unloading device, making it convenient for personnel to use. BRIEF DESCRIPTION OF THE DRAWINGS
