Description

TECHNICAL FIELD

[0001] The utility model relates to a measuring device especially relates to a building construction site intelligent measuring device. BACKGROUND

[0002] In the building construction scene, the measuring equipment is the core tool for realizing accurate construction, and common equipment includes laser level, total station and electronic level, etc. These devices are widely used in ground leveling, wall verticality detection, steel structure installation positioning, etc. For example, in the floor pouring stage, the operator needs to project the reference line through the laser level, and cooperate with the ruler to measure the elevation of multiple points. In the wall building process, the electronic inclinometer needs to be repeatedly used to check the verticality deviation. The traditional bubble level and tape measure are often used for local leveling and size rechecking of small components. Modern devices are usually fixed by tripod, and the reference surface is calibrated by automatic leveling system, and then the data is collected by optical or electronic sensor, and the construction personnel adjusts manually according to the displayed value or marking line. Some intelligent devices can also synchronize the measurement data to the terminal through the wireless module to form a three-dimensional space coordinate model to assist construction decision-making.

[0003] However, the existing measuring equipment has significant defects in human-computer interaction: the traditional leveling tool needs the operator to repeatedly visually compare the bubble position of the level, and adjusts the amplitude by experience, which leads to low efficiency of single operation and easy visual fatigue; although the intelligent device can automatically output data, it lacks real-time human-computer cooperation mechanism, for example, it cannot directly guide the operator to adjust the angle and height of the construction instrument through tactile feedback or sound and light prompt, and still needs to rely on personnel to repeatedly check the instrument and manually calibrate. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a building construction site intelligent measuring device which accelerates the leveling speed of the measuring device through human-computer interaction.

[0005] To achieve the above purpose, the utility model technical scheme is as follows: a building construction site intelligent measuring device, comprising a measuring instrument and a support assembly for supporting the measuring instrument, the support assembly comprising at least three telescopic support legs, further comprising a leveling assembly, the support assembly comprising a horizontally arranged support table, the measuring instrument being arranged on the support table, the leveling assembly comprising a bearing disc and a display screen for displaying where the support leg needs to be adjusted, the bearing disc being provided with a ball which can slide therein, the number of corners of the bearing disc corresponding to the number of support legs and the corners of the bearing disc being arranged correspondingly to the positions of the support legs, and a sensor for measuring the distance between the ball and the corner of the bearing disc being arranged on each corner of the bearing disc.

[0006] The utility model discloses beneficial effect is: through the position offset of ball in the bearing disc and the distance change of each side angle sensor, establish the corresponding relation of support leg and bearing disc side angle, when one side sensor detects the distance with ball is the least, show that the support leg height of this side corresponding needs adjustment. The display screen directly indicates the support leg that needs operation through visual mode, avoided the cumbersome operation that needs repeatedly observed bubble level in traditional leveling process. The structure realizes the quantitative measurement of leveling process, can reduce artificial judgment error, especially suitable for the complex working condition that the ground exists local concave and convex. As a preferred mode, the sensor can adopt the laser ranging module of annular array layout, and each module corresponds a bearing disc side angle, and its measurement data generates three-dimensional coordinate system interface with direction arrow after algorithm processing, and the operator can directly see the support leg number and adjustment level that need adjustment.

[0007] Further, the bearing disc center is provided with a placing area for placing the ball, the placing disc is divided into several independent placing areas according to the number of bearing disc side angles, and a ball is arranged in each placing area, and a communication channel is arranged between each placing area and the corresponding bearing disc side angle for communicating the two.

[0008] The structure ensures that each ball can only move in a specific communication channel in a one-way manner through physical isolation, preventing measurement errors caused by mutual interference of multiple balls. The independent placing area design makes the adjustment operation of each support leg independent. When a side support leg is adjusted in place, the corresponding ball stays in a changed position in the communication channel until the distance between the several balls and the bearing disc side angle is equal, indicating that leveling is successful. At this time, the operator can be prompted on the display screen. As a preferred mode, the communication channel can adopt a tapered guide groove structure, the inlet width of which is greater than the diameter of the ball, and the end width is slightly smaller than the diameter of the ball, ensuring that the ball can only roll in one direction to the measurement position under the action of gravity, and will be locked by the guide groove when moving in the opposite direction.

[0009] Further, the edge of the placing disc is provided with a blocking plate corresponding to the number of placing areas, which is used to prevent the ball from entering the communication channel before leveling.

[0010] The blocking plate forms a temporary closed structure through physical blocking, and even if jolting or tilting occurs during transportation, the ball is still limited in the placing area, ensuring the reliability of the initial state of the device after it reaches the site. This design also maintains the reset state of the leveling system in the non-use state, avoiding sensor zero drift caused by long-term pressure. As a preferred mode, the blocking plate can be designed as a rotatable sector-shaped baffle, and a torsional spring is arranged at the shaft of the baffle. Under normal circumstances, the spring force keeps the baffle in a vertical blocking state. When leveling operation is needed, the baffle is rotated to a horizontal state by pressing the top of the baffle downward, thereby releasing the closure of the communication channel.

[0011] Further, the leveling assembly further comprises a moving column and a positioning sleeve sliding on the moving column, the positioning sleeve is connected with each blocking plate respectively to drive the blocking plate to move up and down, a plurality of positioning holes are arranged on the moving column, and a telescopic inserting column is arranged on the positioning sleeve, the inserting column and the positioning hole are matched to position the position of the blocking plate.

[0012] The linkage mechanism realizes synchronous control of multiple blocking plates, and all blocking mechanisms can be opened and closed through single-point operation, thereby significantly improving operation efficiency. The cooperation of the positioning hole and the inserting column ensures that the blocking plate has a clear position locking in the working and storage states, thereby avoiding accidental displacement caused by vibration. As a preferred mode, the moving column can adopt a hexagonal prism structure, a corresponding hexagonal guide groove is arranged in the positioning sleeve, smooth sliding is ensured and rotation misplacement is prevented, and the end of the inserting column is designed as a hemispherical elastic head, thereby forming an interference fit with the conical positioning hole, and ensuring the positioning firmness.

[0013] Further, the leveling assembly further comprises a back-off plate made of transparent material, the back-off plate is arranged at the end of the communication channel close to the sensor side, and the back-off plate is slidingly arranged in the communication channel.

[0014] The transparent material facilitates observation of the position state of the ball, and the sliding back-off plate can manually or automatically push the measured ball back to the initial position, thereby preparing for next measurement. This design is particularly suitable for continuous multiple measurement working conditions, and the physical reset ensures the consistency of the reference for each measurement. As a preferred mode, the back-off plate can be integrated with a spring reset mechanism, a limiting buckle is arranged at the end of the sliding track of the back-off plate, when reset is needed, the operator pulls the back-off plate backward to the limiting position, and the ball is stably pushed back to the placement area after the spring is released, and the contact surface between the ball and the back-off plate in the reset process can be designed as a wavy anti-skid pattern to enhance the thrust transmission efficiency.
