Description

Technical Field

[0001] This application relates to the technical field of engineering supervision, and particularly to a flatness meter for engineering quality inspection. Background Art

[0002] A flatness meter is an instrument for measuring the flatness of a road surface. Flatness is an important indicator in road evaluation and construction acceptance, mainly reflecting the flatness of the longitudinal section profile curve of the road surface. When it is a smooth curve, it indicates that the road surface is relatively flat, or the flatness is relatively good, otherwise it indicates that the flatness is relatively poor.

[0003] According to a flatness meter for supervision disclosed in Chinese Patent Publication No. CN215003475U, this patent enables the laser to be adjusted and rotated in any direction by setting a damping sleeve, thereby achieving the effect of being able to measure both the wall surface and the ground surface. However, there are still certain deficiencies in the actual operation of this patent. Since the flatness meter only detects the flatness of the ground surface and the verticality of the wall surface in most cases, although this patent can achieve stepless rotation adjustment, it does not set relevant limit structures at the key points parallel and perpendicular to the ground, resulting in the need for operators to spend more time and effort to adjust the angle to make the laser parallel to the ground or perpendicular to the wall surface, reducing the efficiency of flatness detection, and thus there is a certain room for improvement in the practicality of the existing flatness meter for supervision.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0031] Please refer to Figures 1-4 , the present application provides a technical solution: a flatness meter for engineering quality inspection, including a base 1, a support plate 201 is fixedly connected to the top of the base 1, a fixing plate 202 is fixedly connected to the front of the support plate 201, a lead screw 203 is rotatably connected between the bottom of the fixing plate 202 and the top of the base 1 through a bearing, a leveling component 400 for leveling the base 1 is installed at the bottom of the base 1, and an adjustment mechanism for sliding and rotating to adjust the laser emission position is installed on the outer side of the lead screw 203

[0032] Through the combined use of the leveling component 400 at the bottom of the base 1, the sliding component 500 and the adjusting component 600 at the top, the convenience of the supervision personnel during the adjustment operation can be greatly improved, enabling the supervision personnel to easily judge whether the rotation angle is in place, thereby improving the efficiency of flatness detection. At the same time, the height adjustment method is optimized, allowing the supervision personnel to more conveniently and accurately adjust the height of laser emission, thereby effectively improving the practicality of the flatness meter for supervision

[0033] It should be noted that a bubble level 204 is fixedly installed on the top of the base 1. Under the action of the bubble level 204, it is convenient for the operator to judge whether the base 1 is parallel to the ground. The top end of the screw rod 203 penetrates through the bottom of the fixing plate 202 and is fixedly installed with a handle 206. The screw rod 203 can be conveniently rotated through the handle 206.

[0034] In this embodiment, the adjustment mechanism is a structure for adjusting the position and angle of laser emission.

[0035] As Figure 1 、 Figure 2 and Figure 4 shown, the adjustment mechanism includes a sliding component 500 installed on the outside of the screw rod 203 and an adjustment component 600 installed on the front of the sliding component 500.

[0036] It should be noted that under the action of the adjustment mechanism, the functions of lateral adjustment and rotational adjustment can be performed.

[0037] In this embodiment, the adjustment component 600 is a structure for facilitating the adjustment of the laser emission angle.

[0038] As Figure 1 、 Figure 2 and Figure 3 shown, the adjustment component 600 includes a mounting plate 601, two mounting blocks 602 detachably connected to the front of the mounting plate 601, two damping rotating shafts 603 respectively rotatably connected to opposite sides of the two mounting plates 601, a laser emitter body 604 fixedly installed between opposite ends of the two damping rotating shafts 603, two fixed boxes 605 respectively fixedly connected to opposite sides of the two mounting blocks 602, a telescopic rod 606 fixedly connected to the inside of the fixed box 605, a spring 607 fixedly connected to the inside of the fixed box 605, a limiting plate 608 fixedly connected to the front end of the telescopic rod 606, four limiting blocks 609 respectively fixedly connected to the inside of the two fixed boxes 605, and a spherical block 610 fixedly connected to the front of the limiting plate 608; spherical grooves 611 for inserting the corresponding spherical blocks 610 are provided at the top and back of the damping rotating shaft 603.

[0039] It should be noted that a communication hole 3 is provided in the top of the base 1. The communication hole 3 is located at the bottom of the laser emitter body 604, and the front of the communication hole 3 is open. Under the action of the communication hole 3, the laser beam can normally emit forward. Among them, when the spherical block 610 is inserted into the inside of the corresponding back spherical groove 611, the laser emitter body 604 is perpendicular to the ground, and the emitted beam is parallel to the ground at this time. When the spherical block 610 is inserted into the inside of the corresponding top spherical groove 611, the laser emitter body 604 is parallel to the ground, and the emitted beam is perpendicular to the ground at this time.

[0040] In addition, the laser emitter body 604 is a device capable of emitting visible light beams such as infrared beams, and a small battery is detachably connected inside. The front of the fixed box 605 is open. The spring 607 is located outside the corresponding telescopic rod 606. The front of the spring 607 is fixedly connected to the back of the corresponding limit plate 608, enabling the spring 607 to be stably compressed. The back of the limit block 609 abuts against the front of the corresponding limit plate 608, and the limit block 609 can limit and block the limit plate 608.

[0041] At the same time, two locking bolts are threadedly connected to the front of the mounting plate 601. The end of the locking bolt passes through the front of the sliding block 503 and fits against the outside of the sliding rod 502. The locking bolt can abut against and limit the sliding block 503, improving the overall stability.

[0042] In this embodiment, the sliding assembly 500 is a structure for horizontally adjusting the laser emission position.

[0043] As Figure 1 and Figure 2 shown, the sliding assembly 500 includes a sliding box 501 threadedly connected to the outside of the lead screw 203, a sliding rod 502 fixedly connected to the inside of the sliding box 501, a sliding block 503 slidably connected to the outside of the sliding rod 502, a scale plate 504 fixedly connected between the top of the base 1 and the bottom of the fixed plate 202, and an indicating block 505 fixedly connected to the left side of the sliding box 501 and fitting against the front of the scale plate 504.

[0044] It should be noted that two positioning rods 205 are fixedly connected between the bottom of the fixed plate 202 and the top of the base 1. The two positioning rods 205 are symmetrically distributed left and right. The bottom end of the positioning rod 205 passes through the top of the sliding box 501, enabling the sliding box 501 to be limited by the two positioning rods 205, so that it can be driven by the lead screw 203 for lifting adjustment. The front of the sliding box 501 is open. The front of the sliding block 503 is fixedly connected to the back of the mounting plate 601, and the mounting plate 601 can move left and right together with the sliding block 503 for adjustment.

[0045] In this embodiment, the leveling assembly 400 is a structure for adjusting the base 1 to a position parallel to the ground.

[0046] As Figure 1 shown, the leveling assembly 400 includes four support cylinders 401 fixedly connected to the bottom of the base 1, threaded rods 402 threadedly connected to the inside of the support cylinders 401, and feet 403 hinged to the bottom ends of the threaded rods 402 through ball joints.

[0047] It should be noted that the four support cylinders 401 are evenly distributed at the four corners of the bottom of the base 1. The bottom of the support cylinder 401 is open, allowing the threaded rod 402 to rotate normally inside the support cylinder 401.

[0048] The working principle of the above embodiment is as follows:

[0049] When it is necessary to detect the flatness of the road surface, place the whole device on the road surface to be detected, and rotate the threaded rod 402 so that the corresponding support cylinder 401 can move up or down. By adjusting the four support cylinders 401 and observing the bubble level 204, the base 1 can be adjusted to a position parallel to the ground. Rotate the handle 206 to make the lead screw 203 rotate. Under the positioning and matching action between the two positioning rods 205, the sliding box 501 can be adjusted up and down. With the use of the indicating block 505 and the scale plate 504, it is convenient for the operator to observe the current height. Rotate the laser emitter body 604 so that the spherical block 610 is inserted into the inner side of the corresponding rear spherical groove 611. At this time, the operator's hand will feel a certain resistance and will also hear the sound of structural collision, indicating that the rotation is in place. Since the base 1 is parallel to the ground, when the spherical block 610 is inserted into the inner side of the corresponding rear spherical groove 611, the laser emitter body 604 is perpendicular to the base 1, so the laser emitter body 604 is also perpendicular to the ground. Start the laser emitter body 604 to emit a laser beam parallel to the ground. By measuring the distances between multiple laser points and the road surface, the flatness of the road surface can be obtained.

[0050] Compared with the prior art, the flatness meter for engineering quality inspection can greatly improve the convenience of the supervisor during the adjustment operation through the cooperation of the leveling component 400 at the bottom of the base 1, the sliding component 500 at the top, and the adjustment component 600. It enables the supervisor to easily judge whether the rotation angle is in place, thus improving the efficiency of flatness detection. At the same time, it also optimizes the height adjustment method, allowing the supervisor to more conveniently and accurately adjust the height of the laser emission, thereby effectively improving the practicality of the flatness meter for supervision and solving the disadvantage that the existing flatness meter for supervision is not convenient during the actual rotation adjustment process.
