Description

Technical Field

[0001] The invention belongs to the technical field of measuring rulers, in particular to a verticality measuring device for building construction. Background Art

[0002] During the house construction process, verticality is an indicator that measures the degree of conformity of the wall in space with the vertical reference line (usually the direction of gravity, that is, the direction of the plumb line). From the perspective of structural safety, walls with good verticality can ensure that the wall evenly bears the load transmitted from the upper structure, avoiding uneven force caused by wall tilt, which may cause structural safety hazards.

[0003] A two-meter ruler is a commonly used tool for measuring the verticality of indoor walls. The operator places one side of the ruler against the wall, observes the gap between the ruler and the wall, and measures the width of the largest gap by inserting a feeler gauge into the gap. This width value can reflect the degree of deviation of the wall relative to the vertical direction within the two-meter range. During the measurement process, since the operator manually inserts the feeler gauge into the gap, the operator can only judge the largest part of the wall gap by visual inspection. Therefore, in order to ensure the accuracy of the measurement, the operator needs to adjust the insertion position of the feeler gauge several times to ensure the accuracy of the measurement data. At the same time, when the ruler is close to the wall, if the wall is cut obliquely as a whole, at this time, by placing one side of the ruler close to the wall and measuring with the feeler gauge, the measured data will be biased, because the deviation value reflected by the ruler at this time may not be a simple deviation of the verticality of the wall, but also includes additional errors caused by the overall tilt of the wall.

[0004] Therefore, in order to solve the above problems, a verticality measuring device for building construction is proposed. Summary of the invention

A rack is also movably connected to the inside of the slider, and the rack passes through the elastic block. A slope is provided on the rack, and the upward movement of the rack can cause the slope to squeeze the elastic block, thereby causing the elastic block to escape from the one-way slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The above scheme makes the fixed ruler close to the wall through the convex seat, and the elastic push rod is also compressed and contacts the wall. Then the monitoring component detects whether the vertical ruler is in a vertical state, and controls the adjustment mechanism to drive the vertical ruler to rotate and adjust the vertical ruler to a vertical state. At this time, the initial position of the pick is recorded as L0. Then the operator moves the slider downward, so that the end of the pick moves downward along the wall. The horizontal displacement L of the elastic push rod during the downward process is recorded at all times by the data processing module. n The vertical displacement H of the slider is monitored in real time by the distance sensor.

In the above scheme, the slider drives the spring gear member downward so that the spring part on the spring gear member is compressed and stored. At the same time, the slider also drives the elastic block downward along the one-way slot. When the operator makes a mistake and releases the movement of the slider, the elastic block and the one-way slot are engaged to prevent the spring stored on the spring gear member from driving the slider upward to reset. 3. The above scheme moves the rack 1 upward to make the slope squeeze the elastic block, so that the elastic block is separated from the one-way slot. When the vertical surface below the slope abuts against the elastic block, the operator can release the rack 1. At this time, the slider will move upward under the action of the clockwork gear.

The above scheme pulls down rack 2 and the limit rod and drives rack 1 upward through the transmission of the limit rod. When the limit rod goes down, it also drives the cam shaft to slide in the straight groove, so that the connecting rod rotates, and drives the damping wheel to contact the outer edge of the ring and reduce the speed of the spring gear when it rotates and resets, thereby avoiding the situation where the slider rebounds quickly and causes a collision.

The photoelectric sensor 21 is used to detect whether the through hole 23 is on the same axis as the photoelectric sensor 21. The adjustment mechanism 3 includes a gear motor 31 fixedly connected to the bottom of the vertical ruler 12, and a gear 1 32 and a worm 33 are also movably connected to the bottom of the vertical ruler 12. The gear 1 32 is fixedly sleeved on the worm 33, and the output end of the gear motor 31 is meshed and connected with the gear 1 32; A worm gear arc segment 121 is fixedly connected to the bottom of the vertical ruler 12 , and the worm 33 is meshedly connected with the worm gear arc segment 121 .

[0019] By adopting the above scheme, the fixed ruler 11 is brought close to the wall through the convex seat 13, and the elastic push rod 42 is also compressed and contacts the wall. Then, the monitoring component 2 detects whether the vertical ruler 12 is in a vertical state, and the vertical ruler 12 is driven to rotate by controlling the adjustment mechanism 3 to adjust the vertical ruler 12 to a vertical state. At this time, the initial position of the paddle 43 is recorded as L0. Then, the operator moves the slider 41 downward, so that the end of the paddle 43 moves downward along the wall, and the horizontal displacement L of the elastic push rod 42 in the downward process is constantly recorded by the data processing module 45. n The displacement H of the slider 41 in the vertical direction is monitored in real time by the distance sensor 46.

[0020] like Figure 4-Figure 10 As shown, a tooth groove 122 is provided on the vertical ruler 12; a spring gear 412 is elastically connected inside the slider 41, and the spring gear 412 is also meshed with the tooth groove 122.

When the rack 52 moves upward, the slope 53 can squeeze the elastic card block 51, so that the elastic card block 51 is separated from the one-way card slot 123; a stopper 124 located above the rack 52 is fixedly connected to the top of the vertical ruler 12; With the above solution, the slider 41 drives the spring gear 412 downward so that the spring part on the spring gear 412 is compressed and stores force. At the same time, the slider 41 also drives the elastic block 51 downward along the one-way slot 123. When the operator makes a mistake and releases the movement of the slider 41, the elastic block 51 and the one-way slot 123 are engaged with each other to avoid the situation that the spring force on the spring gear 412 drives the slider 41 upward to reset. When the slider 41 needs to be reset upward, the rack 1 52 is moved upward to make the slope 53 squeeze the elastic block 51, so that the elastic block 51 is disengaged from the one-way slot 123. When the vertical surface below the slope 53 abuts against the elastic block 51, the operator can release the rack 1 52. At this time, the slider 41 will move upward under the action of the clockwork gear 412. When the slider 41 moves upward to the top, the stopper 124 will first squeeze the top of the rack 1 52 and release the squeezing of the elastic block 51, and the elastic block 51 will be reset by its own elastic force and be clamped into the one-way slot 123 again to reset.

[0021] like Figure 6-Figure 10 As shown, a transmission assembly 6 is also provided inside the slider 41, and the transmission assembly 6 includes a rack 2 61, a limit rod 62, a cross bar 63 and a gear 2 64 movably connected to the inside of the slider 41, the rack 2 61 and the bottom ends of the limit rod 62 are fixedly connected through the cross bar 63, and the gear 2 64 is respectively meshed with the upper part of the rack 2 61 and the rack 1 52, and the bottom ends of the rack 2 61 and the limit rod 62 extend to the bottom of the slider 41 and are elastic; A damping assembly 7 is also provided inside the slider 41. The damping assembly 7 includes a connecting rod 71 whose middle part is hinged inside the slider 41. A damping wheel 72 is movably connected to one end of the connecting rod 71. A straight slot 73 is provided on the other end of the damping wheel 72. A convex shaft 74 that can slide in the straight slot 73 is fixedly connected to the limiting rod 62. The spring gear 412 is symmetrically provided with an annular outer edge 4121, and the connecting rod 71 rotates to make the damping wheel 72 contact with the annular outer edge 4121; By adopting the above scheme, rack 1 52 is moved upward by pulling down rack 2 61 and limit rod 62 and the limit rod 62 drives rack 1 52 to move upward. When limit rod 62 moves downward, cam shaft 74 is also driven to slide in straight slot 73, thereby rotating connecting rod 71 and driving damping wheel 72 to contact annular outer edge 4121 and reduce the speed of rotation and reset of clockwork gear 412, thereby avoiding the occurrence of collision caused by rapid rebound of slider 41.

[0022] The working principle and use process of the present invention: First, the operator places the fixed ruler 11 close to the wall through the convex seat 13, and the elastic push rod 42 is compressed and contacts the wall. Then, the monitoring component 2 detects whether the vertical ruler 12 is in a vertical state, and the vertical ruler 12 is driven to rotate by controlling the adjustment mechanism 3 to adjust the vertical ruler 12 to a vertical state. At this time, the initial position of the paddle 43 is recorded as L0. Then, the operator moves the slider 41 downward, so that the end of the paddle 43 moves downward along the wall, and the horizontal displacement L of the elastic push rod 42 in the downward process is constantly recorded by the data processing module 45. nThe displacement H of the slider 41 in the vertical direction is monitored in real time by the distance sensor 46. At this time, the displacement L is converted into n and displacement H are arranged and plotted into a curve graph and displayed on the protection component 5, so that the operator can judge the flatness of the wall at any position measured by the device; When the slider 41 moves downward, it also drives the spring gear 412 downward, so that the spring part on the spring gear 412 is compressed and stores force, so as to facilitate the subsequent reset of the slider 41. At the same time, when the slider 41 moves downward, it also drives the elastic block 51 downward along the one-way slot 123. When the operator makes a mistake and releases the movement of the slider 41, the elastic block 51 and the one-way slot 123 are engaged with each other to avoid the situation that the spring force on the spring gear 412 drives the slider 41 upward to reset. When the slider 41 needs to be reset, the rack 1 52 is moved upward so that the slope 53 squeezes the elastic block 51, so that the elastic block 51 is separated from the one-way slot 123. When the vertical surface below the slope 53 abuts against the elastic block 51, the operator can release the rack 1 52. At this time, the slider 41 will move upward under the action of the clockwork gear 412. When the slider 41 moves upward to the top, the stopper 124 will first squeeze the top of the rack 1 52 and release the squeezing of the elastic block 51. The elastic block 51 will be reset by its own elastic force and will be clamped into the one-way slot 123 again to reset. The operator can also pull down rack 2 61 and limit rod 62 and move rack 1 52 upward through the transmission of limit rod 62. When limit rod 62 moves downward, it will also drive cam 74 to slide in straight slot 73, so that connecting rod 71 rotates, and drives damping wheel 72 to contact annular outer edge 4121 and reduce the speed of rotation and reset of clockwork gear 412, so as to avoid the situation that slider 41 rebounds quickly and causes collision.
