Description

Technical Field

[0001] The present invention relates to the technical field of measurement, and particularly relates to a flatness detection device for buildings. Background Art

[0002] Buildings are the general term for buildings and structures. They are artificial environments created by people to meet the needs of social life, using the mastered material and technical means and applying certain scientific laws and aesthetic principles. In the construction industry, after the wall construction is completed, it is necessary to detect the flatness of the wall surface, that is, to detect the flatness of the wall surface to determine whether the wall meets the standards. At present, the flatness detector commonly used in production consists of a straightedge and a wedge-shaped feeler gauge. The usage method is to place the straightedge close to the wall surface, insert the wedge-shaped feeler gauge at the gap, read the reading on the wedge-shaped feeler gauge, and record the reading in a manual. It is very inconvenient to use and has low accuracy.

[0003] To solve the above problems, a Chinese invention patent with the publication number CN109764834B discloses a flatness detection device for construction engineering quality, including a crossbeam support and a connection mechanism. A first screw rod is further arranged below the crossbeam support. A first nut sleeve is threadedly connected to the first screw rod. An electric push rod is fixedly installed at the bottom of the first nut sleeve. The telescopic end of the electric push rod is fixedly installed with the connection mechanism. When this patent conducts flatness detection, the position where the right side plate is located is selected as the reference position for detecting the flatness of the detection surface. The infrared capturing mechanism captures the infrared rays emitted by the infrared emitting mechanism and records in real time the distance between the infrared receiving point and the detection surface. Since the infrared rays are emitted horizontally, the distance between the receiving point and the detection surface is the distance between the emitting point and the detection surface, thereby realizing the detection of the flatness of the detection surface, eliminating the need for workers to manually measure, record, and calculate, not only reducing the labor intensity of workers, but also improving the accuracy of flatness detection.

[0004] During the actual use of the above patent, after the left side plate and the right side plate are placed on a flat ground, the flatness of the wall surface is detected. However, during the detection period, the movements of the rotary motor, the first screw rod, and the first nut sleeve will cause the left side plate and the right side plate to shake, and further cause displacement of the left side plate and the right side plate, directly affecting the accuracy of the detection. If the ground to be detected is inclined, the left side plate and the right side plate will directly fall after being placed on the ground without external force, resulting in the inability to carry out the detection work. If two people are used to position the left side plate and the right side plate respectively during the detection period, it will directly increase the detection cost, and there may also be accidental injuries to the staff during the detection. Summary of the Invention

[0005] The present invention aims to provide a flatness detection device for buildings to solve the problem that the existing flatness detection device is prone to inaccurate detection in its usage method.

[0006] To achieve the above object, the present invention adopts the following technical solution: A flatness detection device for construction, including a detection part, further including a side seat, on which a first clamping plate and a second clamping plate are provided; a chute is horizontally provided on the first clamping plate, and a movable block is slidably connected in the chute, and the detection part is fixedly connected to the movable block;

[0007] A threaded rod for abutting against the wall surface is threadedly connected to the first clamping plate, and the threaded rod is perpendicular to the first clamping plate and the second clamping plate; further including an adjusting mechanism for adjusting the position of the movable block.

[0008] The principle and advantages of this solution are as follows:

[0009] 1. In this solution, the end of the wall is placed between the first clamping plate and the second clamping plate, so that the wall is limited between the first clamping plate and the second clamping plate; and by rotating the threaded rod to move in the direction away from the second clamping plate of the wall, the threaded rod abuts against the side of the wall away from the second clamping plate, that is, the clamping effect on the wall can be strengthened through the threaded rod and the second clamping plate, so that the side seat can be more stably positioned on the wall, and then the detection part on the movable block can be more stably positioned on the wall. Compared with the current technology, in this solution, the detection part is positioned on the wall surface, so that it will not be affected by the inclination of the ground and affect the detection accuracy, nor will the detection accuracy be affected by shaking, that is, the position of the detection part will not change during the detection in this solution, effectively ensuring the accuracy of the flatness detection of the wall surface.

[0010] 2. When this solution is used, when the width of the wall surface to be measured is less than the detection width of the detection, the flatness of the entire wall surface can be directly detected by the detection part; when the width of the wall surface to be measured is greater than the detection width of the detection, the adjusting structure can be used to drive the movable block to move, and then drive the detection part to move, so as to detect the flatness of different positions of the wall surface, with strong practicability.

[0011] Further, the adjusting mechanism includes a rotating shaft and a rack. The rotating shaft is rotatably connected to the first clamping plate and is perpendicular to the first clamping plate; the rack is fixedly connected to the movable block and is slidably connected to the chute; a gear meshing with the rack is rotatably connected to the rotating shaft, and the gear is located in the chute; further including a stopping part for stopping the rotating shaft.

[0012] With the above settings, when the rotating shaft is rotated, the rotating shaft drives the gear to rotate. The gear meshes with the rack to drive the rack to move, and then the rack drives the movable block to move horizontally, and then drives the detection part to move synchronously; when the detection part moves to the specified detection position, the rotating shaft is stopped by the stopping part, and then the detection part is stopped through the gear, the rack and the movable block.

[0013] Further, the stopping portion includes a cylinder and a first wedge. The cylinder is fixedly connected to the rotating shaft, and the cylinder is coaxially arranged with the rotating shaft. A first wedge surface for pressing the first wedge is provided on the side wall of the cylinder; the threaded rod includes, from top to bottom, a first threaded section, a shaft section, and a second threaded section for threaded connection with the first clamping plate that are connected to each other. The diameter of the shaft section is smaller than the diameters of the first threaded section and the second threaded section;

[0014] The first wedge is rotatably connected to the shaft section. A strip-shaped groove is provided on the first wedge along the length direction of the first wedge. The shaft section is located in the strip-shaped groove, and the shaft section is in sliding fit with the strip-shaped groove; a special-shaped groove is provided on the side seat. One end of the first wedge away from the cylinder is in sliding fit with the special-shaped groove. A first spring is provided in the special-shaped groove, and the first spring is located on the movement track of the end of the first wedge away from the cylinder;

[0015] A plurality of stopping grooves for the first wedge to extend into are circumferentially provided on the rotating shaft. The first wedge is in sliding fit with the stopping grooves, and the stopping grooves are located below the cylinder.

[0016] Through the above settings, when the detection portion moves to the specified detection position, the rotating shaft stops rotating; rotate the threaded rod so that the threaded rod moves towards the wall; during the movement of the threaded rod, specifically during the movement of the first threaded section, the shaft section, and the second threaded section, since the first wedge is rotatably connected to the shaft section, the first wedge will not rotate synchronously with the shaft section. Therefore, the shaft section drives the first wedge to move synchronously towards the wall; the shaft section continues to move, so that the first wedge is affected by the wedge surface and moves leftward relative to the shaft section along the path of the strip-shaped groove, and the first spring is compressed; the shaft section continues to move further, so that the first wedge crosses the cylinder, and the first wedge slides into the stopping groove under the action of the first spring, thereby realizing the stopping of the rotating shaft, avoiding the rotation of the rotating shaft, and further realizing the stopping of the rack and the movable block, that is, realizing the stopping and positioning of the detection portion; therefore, according to the detection needs, this solution can adjust the detection portion to move to the position on the wall that needs to be detected, and has strong practicability.

[0017] Further, limiting blocks are provided on both sides of the gear in the chute, and the distance between the two limiting blocks is equal to the thickness of the gear.

[0018] Through the above settings, during the rotation of the rotating shaft driving the gear, the gear is located between the two limiting blocks, so that the gear will not displace along the axial direction of the rotating shaft, thereby improving the structural stability.

[0019] Further, the special-shaped groove includes, from top to bottom, a vertical groove, a transition groove, and a horizontal groove that are sequentially communicated. When the first wedge surface presses the first wedge, the end of the first wedge away from the cylinder slides in the vertical groove, the transition groove, and the horizontal groove in sequence; the first spring is arranged in the horizontal groove.

[0020] With the above settings, during the movement of the shaft section driving the first wedge block, the left end of the first wedge block slides successively from top to bottom in the vertical groove, the transition groove, and the horizontal groove, so as to guide the vertical movement of the first wedge block and the threaded rod, and at the same time prevent the first wedge block from rotating synchronously with the shaft section.

[0021] Furthermore, a first auxiliary groove is provided in the first clamping plate, a second auxiliary groove is provided on the side seat, and a third auxiliary groove is provided in the second clamping plate. The first auxiliary groove, the second auxiliary groove, and the third auxiliary groove are communicated, and the first auxiliary groove, the second auxiliary groove, and the third auxiliary groove form an inner groove; a second wedge block slides horizontally in the inner groove, and a second spring is provided between the second wedge block and the inner groove; the second threaded section passes through the first auxiliary groove, a ring groove is provided on the second threaded section, and a third wedge block for pressing the second wedge block is rotatably connected in the ring groove; a chamber communicated with the first auxiliary groove is provided in the first clamping plate, the second threaded section passes through the chamber, the third wedge block can rotate and move vertically in the chamber, and the second wedge block extends into the chamber; a top groove communicated with the third auxiliary groove is vertically provided on the surface of the second clamping plate, and a fourth wedge block for abutting against the wall is slidably connected in the top groove, a third spring is provided between the fourth wedge block and the top groove, and the fourth wedge block is located on the movement track of the second wedge block.

[0022] With the above settings, during the movement of the shaft section driving the first wedge block, the second threaded section moves synchronously with the shaft section; the second shaft section drives the third wedge block to rotate in the chamber, and at the same time the second shaft section drives the third wedge block to move towards the wall in the chamber, so that the third wedge block presses the second wedge block to move leftward, and the second spring is compressed; at the same time, the second wedge block presses the fourth wedge block to move towards the wall, and the third spring is compressed, that is, the second threaded section and the fourth wedge block move towards each other; when the first wedge block slides into the stop groove, the second threaded section and the fourth wedge block respectively abut against both sides of the wall, so as to clamp the wall, so that the detection part will not shake or tilt during detection, and further ensure the accuracy of detection.

[0023] Furthermore, a support roller is provided on the side wall of the movable block, a traction rope is wound and fixed on the rotating shaft, and one end of the traction rope away from the rotating shaft is wound and fixed on the support roller.

[0024] With the above settings, during the lateral movement of the movable block, the traction rope on the rotating shaft will be released, and at the same time the movable block pulls the traction rope to move through the support roller. Therefore, the traction rope can support the movable block, and further improve the stability of the structure. Description of the Drawings

When the first wedge surface 62 presses the first wedge 61, one end of the first wedge 61 away from the cylinder 60 slides in the vertical groove 631, the transition groove 632, and the horizontal groove 633 in sequence.

[0033] A first auxiliary groove 701 is formed in the first clamping plate 21, a second auxiliary groove 702 is formed in the side seat 20, and a third auxiliary groove 703 is formed in the second clamping plate 22. The first auxiliary groove 701, the second auxiliary groove 702, and the third auxiliary groove 703 are communicated, and the first auxiliary groove 701, the second auxiliary groove 702, and the third auxiliary groove 703 form an inner groove 70.

[0034] A support roller 80 is fixedly connected to the side wall of the movable block 30. A traction rope 81 is wound and fixedly connected to the rotating shaft 50. One end of the traction rope 81 away from the rotating shaft 50 is wound and fixedly connected to the support roller 80.

[0035] The specific implementation process is as follows:

[0036] During use, the staff moves the side seat 20 to one end face position of the wall, so that one end of the wall is located between the first clamping plate 21 and the second clamping plate 22; rotates the rotating shaft 50, the rotating shaft 50 drives the gear 52 to rotate, the gear 52 meshes with the rack 51 to drive the rack 51 to slide horizontally, and further drives the movable block 30 to move horizontally, that is, drives the detection part 10 to move horizontally to the position to be detected on the wall surface.

[0037] When the detection part 10 moves to the position to be detected on the wall surface, the rotating shaft 50 stops rotating; rotates the threaded rod 40 so that the threaded rod 40 moves towards the wall; during the movement of the threaded rod 40, specifically during the movement of the first threaded section 401, the shaft section and the second threaded section 402, since the first wedge block 61 is rotatably connected to the shaft section, the first wedge block 61 will not rotate synchronously with the shaft section. Therefore, the shaft section drives the first wedge block 61 to move synchronously towards the wall; the shaft section continues to move, so that the first wedge block 61 moves leftward relative to the shaft section along the path of the strip-shaped groove 611 under the action of the wedge surface, and the first spring 64 is compressed; the shaft section continues to move, so that the first wedge block 61 passes over the cylinder 60, and the first wedge block 61 slides into the stop groove 65 under the action of the first spring 64, thereby realizing the stopping of the rotating shaft 50, avoiding the rotation of the rotating shaft 50, and further realizing the stopping of the rack 51 and the movable block 30, that is, realizing the stopping and positioning of the detection part 10; therefore, according to the detection needs, this solution can adjust the detection part 10 to move to the position on the wall surface that needs to be detected, and has strong practicability.

[0038] During the movement of the shaft section driving the first wedge block 61, the left end of the first wedge block 61 slides in the vertical groove 631, the transition groove 632 and the horizontal groove 633 from top to bottom in sequence, which can play a guiding role in the vertical movement of the first wedge block 61 and the threaded rod 40, and at the same time can also prevent the first wedge block 61 from rotating synchronously with the shaft section.

[0039] During the movement of the shaft section driving the first wedge block 61, the second threaded section 402 moves synchronously with the shaft section; the second shaft section drives the third wedge block 73 to rotate in the chamber, and at the same time the second shaft section drives the third wedge block 73 to move towards the wall in the chamber, so that the third wedge block 73 squeezes the second wedge block 71 to move leftward, and the second spring 72 is compressed; at the same time, the second wedge block 71 squeezes the fourth wedge block 74 to move towards the wall, and the third spring 75 is compressed, that is, the second threaded section 402 and the fourth wedge block 74 move towards each other; when the first wedge block 61 slides into the stop groove 65, the second threaded section 402 and the fourth wedge block 74 respectively abut against the two sides of the wall, thereby clamping the wall, so that the detection part 10 will not shake or tilt during detection, and further ensuring the accuracy of detection.

[0040] During the lateral movement of the movable block 30, the towing rope 81 on the rotating shaft 50 is released. At the same time, the movable block 30 pulls the towing rope 81 through the support roller 80. Therefore, the towing rope 81 can support the movable block 30, thereby improving the stability of the structure.

[0041] In this embodiment, rubber layers are fixedly connected to the bottom of the second threaded section 402 and the top of the fourth wedge 74. Since the rubber layer is a flexible material, the rubber layer is used to contact the wall surface instead of the second threaded section 402 and the fourth wedge 74, effectively reducing the wear on the wall surface.

[0042] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
