DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 7 As shown, a construction measurement device provided by an embodiment of the present invention includes a support frame 1, which is composed of a fixed frame 11 and a movable frame 12. The movable frame 12 is telescopically arranged in the fixed frame 11. The support frame 1 is provided with a retractable adjustment mechanism 4, which includes a driving component 41, a telescopic member 42 and a connecting component 43. The connecting component 43 is plugged into the telescopic member 42. The driving component 41 is arranged at one end of the telescopic member 42.

The gravity mechanism 3 includes a gravity frame 31 and a gravity ball 32. A spring 33 is connected between the gravity ball 32 and the gravity frame 31. Guide rods 34 are penetrated at both ends of the gravity frame 31. The measuring mechanism 2 includes a first measuring component 21 and a second measuring component 22. The first measuring component 21 and the second measuring component 22 are respectively arranged on the first measuring component 21 and the gravity frame 31. The second measuring component 22 includes a laser rangefinder 223. A press switch 222 is connected to the bottom of the laser rangefinder 223.

[0022] Furthermore, a support block 13 is fixedly connected to the upper surface of the movable frame 12 , a mounting shaft 52 is rotatably connected between the upper portion of the support block 13 and one end of the movable frame 12 , and an I-shaped shaft 51 is fixedly sleeved on the mounting shaft 52 .

[0023] Specifically, the suspension rope 5 is arranged at one end of the movable frame 12 extending out of the fixed frame 11, and the other end of the movable frame 12 is slidably connected to the fixed frame 11. One end of the telescopic member 42 is fixedly connected to the installation shaft 52. The support block 13 is arranged at the connection between the telescopic member 42 and the installation shaft 52 to support the two. The extension of the telescopic member 42 and the outward extension of the movable frame 12 can drive the suspension rope 5, the measuring mechanism 2 and the gravity mechanism 3 to move synchronously, and the measuring point can be changed to perform multiple measurements to ensure that the measurement result can reflect the overall depth of the groove, rather than the local depth value, thereby improving the accuracy of the measurement.

[0024] Furthermore, the driving assembly 41 includes a rotating rod 411, a worm 412 and a worm wheel 413. The bottom of the rotating rod 411 is rotatably installed on one end of the upper surface of the fixed frame 11. The worm 412 is fixedly sleeved on the rotating rod 411. The worm 412 is meshed and connected with the worm wheel 413. The telescopic member 42 includes a sleeve 421 and a sleeve rod 422. One end of the sleeve rod 422 is threadedly sleeved in the sleeve 421. The worm wheel 413 is fixedly sleeved at one end of the sleeve 421. The sleeve 421 and the sleeve rod 422 are respectively provided with a first thread groove 423 and a through hole 424. The connecting assembly 43 includes a screw 431 and a fastening bolt 432. The screw 431 is threadedly inserted into the movable frame 12, and the bottom passes through the movable frame 12. The fastening bolt 432 passes through the sleeve rod 422 and the bottom is threadedly connected to the upper end of the screw 431. A second thread groove 311 adapted to the bottom of the screw 431 is provided on one side of the gravity frame 31.

[0025] Specifically, the worm 412 is driven to rotate synchronously by rotating the rotating rod 411, and the worm 412 is threadedly matched with the worm wheel 413, so that the worm wheel 413 drives the sleeve 421 to rotate synchronously. One end of the sleeve 421 is rotatably mounted on the fixing frame 11, one end of the sleeve rod 422 is threadedly connected to the sleeve 421, and the other end is fixedly connected to the mounting shaft 52. When the fastening bolt 432 is screwed into the first thread groove 423 and the sleeve rod 422 is pressed tightly, the sleeve rod 422 and the sleeve 421 are integrated as a whole and can rotate synchronously. At this time, the driving assembly can be used 41 drives the telescopic member 42 and the installation shaft 52 to rotate, so as to realize the retraction and extension of the suspension rope 5. When the fastening bolt 432 is inserted into the through hole 424 and passes through the sleeve rod 422, the driving component 41 can only drive the sleeve 421 to rotate. Through the threaded cooperation between the sleeve rod 422 and the sleeve 421, the sleeve rod 422 is gradually extended outward to realize the elongation of the telescopic member 42. The bottom thread of the screw rod 431 is inserted into the movable frame 12, and the upper part is threadedly cooperated with the fastening bolt 432, so that the movable frame 12 and the sleeve rod 422 move synchronously, thereby improving the stability during the movement.

[0026] Furthermore, the first measuring component 21 includes two mounting plates 211, an encoder 212 and two rollers 213. The two mounting plates 211 are fixedly connected to the lower surface of the movable frame 12, the two rollers 213 are rotatably installed in the mounting plates 211, the encoder 212 is fixedly installed on one side of the mounting plate 211, the input end of the encoder 212 is fixedly connected to one end of one of the encoders 212, the suspension rope 5 is wound around the two rollers 213, the bottom is fixedly connected to the upper surface of the gravity frame 31, one side of the upper surface of the gravity frame 31 is fixedly connected with the mounting frame 221, the push switch 222 is fixedly connected to the top inner wall of the mounting frame 221, and the laser rangefinder 223 is fixedly connected to the upper surface of the mounting frame 221.

[0027] Specifically, the weight of the gravity mechanism 3 causes a certain tension in the suspension rope 5. When the retractable and adjustable mechanism 4 causes the mounting shaft 52 to rotate, the gravity mechanism 3 pulls the suspension rope 5 to gradually lengthen it. The friction between the suspension rope 5 and the roller 213 causes the roller 213 to rotate. At this time, the encoder 212 detects the rotation parameters of the roller 213, and accurately obtains the extended length of the suspension rope 5 based on the parameters, thereby obtaining the depth of the groove.

[0028] Furthermore, the upper end of the spring 33 is fixedly connected to the top inner wall of the gravity frame 31, and the lower end is fixedly connected to a mounting cover 36. A connecting tube 35 is fixedly connected to the middle of the upper surface of the mounting cover 36. The connecting tube 35 is covered outside the spring 33. The gravity ball 32 is rotatably connected to the mounting cover 36. Two guide rods 34 are respectively fixedly connected to both sides of the upper surface of the mounting cover 36 and slide through the gravity frame 31. The upper end of one of the guide rods 34 is located on the inner side of the mounting frame 221.

[0029] Specifically, when carrying the device, the gravity mechanism 3 is flipped to a position close to the movable frame 12, and the bottom of the screw rod 431 is threadedly connected to the second thread groove 311 to fix the gravity mechanism 3 to prevent the gravity mechanism 3 from shaking during carrying. The gravity ball 32 is movably arranged inside the gravity frame 31 through the spring 33. During the extension of the suspension rope 5, the gravity mechanism 3 gradually moves downward. When the gravity ball 32 moves to the bottom of the groove, the gravity frame 31 will continue to move under the action of its own gravity, compressing the spring 33 so that the spring 33 is pressed into the connecting tube 35, and the guide rod 34 moves upward relative to the gravity frame 31. Then, the pressing switch 222 is squeezed to turn on the laser rangefinder 223. The laser rangefinder 223 emits a laser to irradiate the movable frame 12 to obtain the measurement parameters and then the groove depth. Through this arrangement, the gravity mechanism 3 can be measured immediately after reaching the bottom of the groove, so as to achieve fast measurement, improve the measurement efficiency, and improve the convenience of the measurement operation.

[0030] like Figure 1-Figure 7 As shown, a method for using a construction measurement device provided by an embodiment of the present invention comprises the following steps: The device is installed by inserting the upper part of the connecting component 43 into the end of the telescopic member 42 close to the driving component 41, and fixing the fixing frame 11 on the ground on one side of the groove, so that the suspension rope 5 and the gravity mechanism 3 are suspended above the groove; Depth measurement: the rotating driving assembly 41 drives the telescopic member 42 and the upper part of the connecting assembly 43 to rotate synchronously, so that the suspension rope 5 gradually extends under the gravity of the gravity mechanism 3. When the gravity ball 32 contacts the bottom of the groove, the gravity frame 31 continues to move downward under its gravity, so that the spring 33 contracts, and the guide rod 34 moves upward relative to the gravity frame 31, pressing the push switch 222 to start the laser rangefinder 223 for detection. During the extension of the suspension rope 5, the depth of the groove is obtained according to the extension length detected by the first measuring assembly 21; For transposition measurement, the upper part of the connecting component 43 is plugged into the end of the telescopic member 42 away from the driving component 41, and the telescopic member 42 is extended by rotating the driving component 41, thereby driving the measuring mechanism 2 and the gravity mechanism 3 to move synchronously, changing the measuring position to meet the measurement requirements at different positions.

[0031] In summary: this kind of construction measurement device can realize the extension or reeling of the suspension rope 5 through the retractable adjustment mechanism 4, thereby realizing the lowering and recovery of the measurement mechanism 2 and the gravity mechanism 3. When the gravity ball 32 moves to the bottom of the groove, the gravity frame 31 continues to move downward, so that the guide rod 34 moves upward relative to the gravity frame 31, and the press switch 222 is squeezed to make the laser rangefinder 223 start measuring. After the gravity mechanism 3 reaches the bottom of the groove, measurement can be carried out immediately, thereby realizing rapid measurement, improving measurement efficiency, and improving the convenience of measurement operation. By changing the plug-in position of the connecting component 43, the telescopic part 42 and the movable frame 12 can also be extended, and the measurement point can be changed for multiple measurements to ensure that the measurement result can reflect the overall depth of the groove, rather than the local depth value. By setting two different measurement methods of the first measuring component 21 and the second measuring component 22, the measurement results can be verified with each other, reducing the limitations of a single measurement method and improving the accuracy of the measurement.
