Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a construction engineering measuring device. Background Art

[0002] A large number of steel pipes are needed in construction projects. Steel pipes have hollow sections and their length is much longer than the diameter or circumference of steel. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes. During construction, workers need to measure the diameter of the steel pipe to check whether it meets the standards.

[0003] A current measuring device for construction engineering, as described in the patent with publication number CN220893218U, comprises: a supporting base plate, a placement groove is provided on the top of the supporting base plate, a supporting plate is fixed to the right end face of the supporting base plate, a fixed top plate is fixed to the top of the supporting plate, a cylinder is installed on the top of the fixed top plate, the power end of the cylinder is connected to and fixed to a limit plate, the limit plate and the placement groove are both arc-shaped parts with arc openings relative to each other, and also includes a positioning rod, two vertically corresponding fixed plates are fixed to the outer wall of the supporting plate, a threaded rod is rotatably installed between the two fixed plates, and a movable plate is screwed on the threaded rod.

[0004] However, when the above-mentioned measuring device for construction engineering is working, the steel pipe is positioned by the cylinder and the limit plate, and the movable plate is driven by the hand-cranked threaded rod to move, so that the positioning rod is moved vertically to the top of the steel pipe, and the diameter is measured by pointing the measuring plate on the scale line. Although the device can measure the diameter of the steel pipe, it is necessary to first position the steel pipe and then measure it manually during the measurement process, and the diameter value is obtained by observing the scale indication with the naked eye. Not only does the measurement process have more steps, resulting in slow efficiency, but the numerical error obtained by naked eye observation is also large, affecting the accuracy of the measurement data.

The diameter data of the steel pipe can be automatically measured through the structure, avoiding the problem of data deviation caused by manual subjective reading of the scale, thereby improving the accuracy of measuring the diameter data of the steel pipe.

[0029] Embodiment 2

[0030] See also Figures 1 to 5 The lifting structure 3 also includes a screw 303 rotatably connected to the upper surface of the base 1, a motor 304 arranged on the inner wall of the base 1 and connected to the screw 303, and a positioning pressure rod 306 welded to the lower surface of the positioning frame 305. The screw 303 and the lifting seat 302 are threadedly connected to each other. By using the motor 304 to drive the screw 303 to rotate, the threaded lifting seat 302 can be moved up and down on the lifting column 301, and the electric-controlled automatic lifting positioning pressure rod 306 can be used to position the steel pipe. There is no need to use an external air pipe to position it using a cylinder, which reduces the investment in equipment and the cost of construction measurement.

[0031] The measuring structure 4 also includes a battery 404 arranged on the inner wall of the base 1, the output end of the battery 404 is connected to the input end of the PLC controller 403, and the output end of the PLC controller 403 is connected to the infrared receiving module 401, the infrared transmitting module 402, the LED display screen 405 and the input end of the motor 304.

[0032] Embodiment 3

[0033] See also Figures 1 to 5 , the infrared receiving module 401 is located at the bottom of the positioning groove 2 on the other side of the blocking bar 5, and the infrared receiving module 401 is located in the middle of the inner wall of the positioning groove 2. By setting the infrared receiving module 401 at one end of the positioning groove 2, it is possible to avoid the steel pipe or other structures blocking the receiving infrared for measurement. And it is located in the middle of the inner wall of the positioning groove 2, so that the receiving point of the infrared receiving module 401 coincides with the bottom end of the steel pipe diameter, so as to improve the accuracy of measuring the steel pipe diameter. The infrared transmitting module 402 is located at the top of the arc plate at the bottom of the positioning pressure rod 306. The infrared receiving module 401 and the infrared transmitting module 402 are on the same vertical line. By connecting the infrared transmitting module 402 and the positioning pressure rod The top of the arc plate of the rod 306 is aligned, so that the infrared transmitting module 402 can be located at the top of the steel pipe diameter to transmit infrared, so that the infrared receiving module 401 on the vertical line can accurately receive infrared to measure the steel pipe diameter, so as to improve the accuracy of measuring the steel pipe diameter and reduce the impact of the actual measurement error on the construction. The arc length of the arc plate at the bottom of the positioning pressure rod 306 is less than the length of the arc of the inner wall of the positioning groove 2. By setting the length of the arc plate at the bottom of the positioning pressure rod 306, the height of the positioning pressure rod 306 that can be lowered to locate the steel pipe can be increased, thereby increasing the lower limit of measuring different diameters of steel pipes, so as to increase the range of measuring diameters of steel pipes of different diameters and improve the practicality of the device.

[0034] Working principle: When in use, place the steel pipe on the upper part of the positioning groove 2 against the baffle 5, use the switch 406 to control the motor 304 to drive the screw 303 to rotate, so that the lifting seat 302 drives the positioning frame 305 to move on the lifting column 301, and stops descending when the arc plate of the positioning pressure rod 306 presses on the top of the steel pipe. At the same time, the infrared transmitting module 402 emits infrared rays, which are received by the infrared receiving module 401 and the data is transmitted to the PLC controller 403 in real time for analysis, so that the measured data is displayed in real time on the LED display screen 405. When the positioning pressure rod 306 stops, the data displayed on the LED display screen 405 is the diameter of the steel pipe.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
