Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly to a device for detecting the parallelism of buildings in construction engineering. Background Art

[0002] When constructing a building, various parameters of the building need to be measured and detected. Among these parameters, parallelism is the most common one. The parallelism of the walls or other components of a building complex can effectively improve the aesthetics and support stability of the building, and also improve the accuracy of construction.

[0003] Existing devices for detecting the parallelism of buildings in construction engineering usually use methods such as measuring distances with a steel tape and the string-hanging method to detect the parallelism of buildings. However, these detection methods are relatively cumbersome to operate, have low efficiency, and are affected by human and external factors. They also cannot quickly detect the parallelism of two groups of buildings according to requirements, reducing the convenience of building detection. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for detecting the parallelism of buildings in construction engineering, which solves the problems of the existing methods for detecting the parallelism of buildings in construction engineering being relatively cumbersome to operate and having low efficiency.

Two groups of distance measuring instruments are symmetrically and fixedly connected to the lower surface of the detection table. A verticality adjustment component is installed on the surface of the detection table. The verticality adjustment component includes a connecting rope and a clamping component. The top end of the connecting rope is fixedly installed at the center of the lower surface of the detection table. The bottom end of the connecting rope is fixedly connected to a plumb bob. The clamping component is used to clamp and fix the sphere after the plumb bob adjusts the distance measuring instrument to be horizontal.

[0006] Preferably, the clamping component includes a plurality of slots. The slots are opened on the surface of the ball socket. A telescopic clamping rod is fixedly connected to the inner wall of the slot. A guide wheel is fixedly arranged at one end of the telescopic clamping rod outside the slot.

[0007] Preferably, the clamping component further includes a plurality of limiting frames. The bottom end of the limiting frame is fixedly connected to the upper surface of the base. The top end of the limiting frame penetrates through the installation table and is fixedly connected to a top seat. The upper side wall of the top seat is fixedly connected to the upper side wall of the support frame.

[0008] Preferably, the limiting frame includes a guiding section, an inclined section and a supporting section from top to bottom.

[0009] Preferably, the telescopic clamping rod includes an outer cylinder body, a partition layer is fixedly connected inside the outer cylinder body, an I-shaped inner rod body is penetrated through the surface of the partition layer, and a spring member is sleeved at the groove of the inner rod body.

[0010] Preferably, a windproof cylinder is fixedly connected to the upper surface of the base, and four groups of moving wheels are fixedly arranged on the lower surface of the base.

[0011] Preferably, a limiting component is installed on the surfaces of the ball sleeve, the base and the detection table. The limiting component includes a plurality of telescopic connecting rods. The tops of the telescopic connecting rods are fixedly connected to the lower surface of the ball sleeve. The bottoms of the telescopic connecting rods are fixedly connected with limiting rings. The plumb bob passes through the limiting rings. A tension spring is sleeved outside the telescopic connecting rods. The two ends of the tension spring are respectively fixedly connected to the bottom end of the upper cylinder body of the telescopic connecting rod and the upper surface of the limiting ring.

[0012] Preferably, the limiting component further includes a plurality of limiting columns, and the tops of the limiting columns are fixedly installed on the lower surface of the detection table.

[0013] Preferably, a supporting protrusion is arranged directly below the limiting ring, and the bottom end of the supporting protrusion is fixedly connected to the upper surface of the base.

[0014] Preferably, the limiting ring is made of ferromagnetic material, and a magnetic ring is fixedly connected to the upper surface of the supporting protrusion.

[0015] Working principle: When detecting a building, move the device to one side of the building. Make the plumb bob perpendicular to the ground and pull the sphere to rotate inside the ball sleeve through the connecting rope, so as to level the detection table, so that the rangefinder can face the building vertically. First, measure the distance from the rangefinder at a lower point to the building. Subsequently, the electric sliding table runs, and the electric sliding table runs to raise the rangefinder, so that the rangefinder can measure the distance from the building at a higher point. If the two measurement results are the same, the building is vertical. If the two measurement results are the same, the building is inclined. When detecting the parallelism of adjacent buildings, move the device to both sides of the buildings, and measure the distances from the two groups of rangefinders to the two groups of buildings at high and low points respectively. When the data measured by the rangefinders at high and low points are the same, the two groups of buildings are horizontal. This device can quickly level the rangefinder through the verticality adjustment component, so as to realize the rapid measurement of the parallelism of the buildings.

[0016] During adjustment in the initial state, the electric slide table operates to drive the guide wheel to descend to the inclined section. At this time, the distance between the inclined section and the sphere increases, so that the telescopic clamping rod does not press tightly against the sphere. As a result, the sphere rotates under the action of the gravity of the plumb bob to level the rangefinder. And at this time, the ball sleeve descends into the inside of the windproof cylinder, and the windproof cylinder intercepts the external wind force to prevent the external wind force from causing the plumb bob to shake, thus affecting the leveling accuracy. After the leveling is completed, the electric slide table drives the guide wheel to rise to the guiding section, and the guiding section limits the guide wheel and the telescopic clamping rod, so that one end of the telescopic clamping rod tightly presses against the sphere, thereby automatically clamping and fixing the sphere after leveling to prevent the sphere from rotating under the influence of external forces such as wind force, which affects the levelness of the rangefinder, realizing the stable measurement of the rangefinder and improving the measurement accuracy of the rangefinder.

[0017] When the plumb bob descends into the inside of the windproof cylinder for adjustment, the magnetic ring adsorbs the limit ring, thereby pulling the limit ring to move downward, so that the plumb bob can be adjusted by breaking away from the restriction of the limit ring. And when the plumb bob rises and the magnetic ring no longer applies magnetic adsorption force to the limit ring, the limit ring presses against the plumb bob upward through the tension spring, thereby supporting the plumb bob to prevent the plumb bob from shaking under the influence of strong wind and preventing the connecting rope from breaking due to excessive shaking amplitude of the plumb bob, resulting in the plumb bob falling and causing safety hazards.

[0018] The present invention provides a device for detecting the parallelism of buildings in construction engineering. It has the following beneficial effects:

[0019] 1. The present invention adjusts the verticality of the detection table through the plumb bob, so that the rangefinder below the detection table can face the building vertically. The device is moved to both sides of the building, and the distances between the two groups of rangefinders and the two groups of buildings are measured from high and low positions respectively. When the data measured by the rangefinders at high and low positions are the same, the two groups of buildings are horizontal. The present device can quickly level the rangefinder through the verticality adjustment component, thereby realizing the rapid measurement of the parallelism of the buildings.

[0020] 2. The present invention limits the guide wheel and the inner rod body through the guiding section, so that the inner rod body tightly presses against the sphere for fixation, thereby automatically clamping and fixing the sphere after leveling to prevent the sphere from rotating under the influence of external forces such as wind force, which affects the levelness of the rangefinder, realizing the stable measurement of the rangefinder and improving the measurement accuracy of the rangefinder.

[0021] 3. The present invention calibrates by lowering the plumb bob into the inside of the windproof cylinder. The windproof cylinder can intercept the external wind force to prevent the external wind force from causing the plumb bob to shake, thereby affecting the leveling accuracy.

[0022] 4. The limiting ring of the present invention supports the plumb bob upward through a tension spring, thereby preventing the plumb bob from shaking under the influence of strong wind, and preventing the connecting rope from breaking due to excessive shaking amplitude of the plumb bob, which may cause the plumb bob to fall and pose a safety hazard. At the same time, it can avoid the plumb bob applying a pulling force to the sphere. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to the attached Figure 1 - Attachment Figure 4 In an embodiment of the present invention, a building parallelism detection device for construction engineering is provided, including a base 1. A support frame 2 is fixedly connected to the upper surface of the base 1. An electric slide table 3 is fixedly embedded inside the support frame 2. A slider of the electric slide table 3 is fixedly connected to a mounting table 4. A ball sleeve 5 is fixedly connected to the lower surface of the mounting table 4. A sphere 6 is nested inside the ball sleeve 5. A T-shaped detection table 7 is fixedly connected to the lower surface of the sphere 6. Two groups of distance measuring instruments 8 are symmetrically and fixedly connected to the lower surface of the detection table 7. A perpendicularity adjustment assembly 9 is installed on the surface of the detection table 7. The perpendicularity adjustment assembly 9 includes a connecting rope 91 and a clamping assembly 93. The top end of the connecting rope 91 is fixedly installed at the center of the lower surface of the detection table 7. The bottom end of the connecting rope 91 is fixedly connected to a plumb bob 92. The clamping assembly 93 is used to clamp and fix the sphere 6 after the plumb bob 92 adjusts the distance measuring instrument 8 to be horizontal.

[0034] Specifically, the electric slide table 3 is used to adjust the height of the distance measuring instrument 8 to achieve multi-point measurement and improve the measurement accuracy. The distance measuring instrument 8 is used to measure the distance from the building wall surface. The plumb bob 92 is used to level the detection table 7 by its own gravity. When detecting a building, the device is moved to one side of the building. The plumb bob 92 is perpendicular to the ground and pulls the sphere 6 to rotate inside the ball sleeve 5 through the connecting rope 91, thereby leveling the detection table 7 so that the distance measuring instrument 8 can face the building vertically. First, the distance from the building is measured at a lower point by the distance measuring instrument 8. Subsequently, the electric slide table 3 operates. The electric slide table 3 drives the mounting table 4 to rise. The mounting table 4 drives the ball sleeve 5, the sphere 6, and the detection table 7 to rise. The detection table 7 rises to raise the distance measuring instrument 8 so that the distance measuring instrument 8 can measure the distance from the building at a higher point. If the two measurement results are the same, the building is vertical. If the two measurement results are different, the building is tilted. When detecting the parallelism of adjacent buildings, the device is moved to both sides of the buildings, and the distances from the two groups of buildings are measured respectively at high and low positions by the two groups of distance measuring instruments 8. When the data measured by the distance measuring instrument 8 at high and low positions are the same, the two groups of buildings are horizontal. This device can quickly level the distance measuring instrument 8 through the perpendicularity adjustment assembly 9, thereby realizing the rapid measurement of the building parallelism.

[0035] Please refer to the attached Figure 3 - Attachment Figure 6, the clamping assembly 93 includes a plurality of slots 931 opened on the surface of the ball sleeve 5. A telescopic clamping rod 934 is fixedly connected to the inner wall of the slot 931. A guide wheel 932 is fixedly arranged at one end of the telescopic clamping rod 934 outside the slot 931. The clamping assembly 93 further includes a plurality of limit frames 936. The bottom end of the limit frame 936 is fixedly connected to the upper surface of the base 1. The top end of the limit frame 936 penetrates through the mounting table 4 and is fixedly connected to a top seat 10. The upper side wall of the top seat 10 is fixedly connected to the upper side wall of the support frame 2. The limit frame 936 includes a guiding section 9361, an inclined section 9362, and a supporting section 9363 from top to bottom.

[0036] Specifically, the top seat 10 is used to support the support frame 2, and the guide wheel 932 is used to move on the surface of the limit frame 936 to reduce resistance. In the initial state, the electric slide 3 operates to drive the guide wheel 932 to descend to the inclined section 9362. At this time, the distance between the inclined section 9362 and the sphere 6 increases, so that the telescopic clamping rod 934 does not tightly press against the sphere 6, so that the sphere 6 rotates under the action of the gravity of the plumb bob 92 to level the rangefinder 8. After leveling, the electric slide 3 drives the guide wheel 932 to rise to the guiding section 9361, and the guiding section 9361 is used to limit the guide wheel 932 and the telescopic clamping rod 934, so that one end of the telescopic clamping rod 934 tightly abuts against the sphere 6, so as to automatically clamp and fix the sphere 6 after leveling, preventing the sphere 6 from rotating under the influence of external forces such as wind, thus affecting the levelness of the rangefinder 8 and realizing the stable measurement of the rangefinder 8 and improving the measurement accuracy of the rangefinder 8.

[0037] Please refer to the appendix Figure 5 , the telescopic clamping rod 934 includes an outer cylinder 9341. A partition layer 9342 is fixedly connected inside the outer cylinder 9341. An I-shaped inner rod 9343 is penetrated through the surface of the partition layer 9342. A spring member 9344 is sleeved at the groove of the inner rod 9343.

[0038] Specifically, the center line of the inner rod 9343 coincides with the midpoint of the sphere 6. The length of the inner rod 9343 plus the guide wheel 932 is slightly greater than the distance from the guiding section 9361 to the sphere 6, so that when the guide wheel 932 moves to the guiding section 9361, one end of the inner rod 9343 located inside the ball sleeve 5 tightly abuts against the sphere 6 for fixation. When the guide wheel moves to the inclined section 9362, the extrusion force applied to the inner rod 9343 disappears. At this time, the inner rod 9343 no longer clamps the sphere 6, and under the elastic force of the spring member 9344, the inner rod 9343 is pushed to slide outwards.

[0039] Please refer to the appendix Figure 7 , the upper surface of the base 1 is fixedly connected with a windproof cylinder 11, and four groups of moving wheels are fixedly arranged on the lower surface of the base 1.

[0040] Specifically, when the guide wheel descends to the inclined section 9362, the ball sleeve 5 descends into the interior of the windproof cylinder 11, and the windproof cylinder 11 intercepts the external wind force, preventing the external wind force from causing shaking on the plumb bob 92, thereby affecting the leveling accuracy. The moving wheels facilitate the movement of the device.

[0041] Please refer to the appendix Figure 7 , a limiting component 12 is installed on the surfaces of the ball sleeve 5, the base 1 and the detection table 7. The limiting component 12 includes a plurality of telescopic connecting rods 121. The tops of the telescopic connecting rods 121 are fixedly connected to the lower surface of the ball sleeve 5. The bottoms of the telescopic connecting rods 121 are fixedly connected with limiting rings 122. The plumb bob 92 passes through the limiting rings 122. A tension spring 126 is sleeved outside the telescopic connecting rod 121. The two ends of the tension spring 126 are respectively fixedly connected to the bottom end of the upper cylinder of the telescopic connecting rod 121 and the upper surface of the limiting ring 122.

[0042] Specifically, the telescopic connecting rod 121 includes an upper cylinder and a lower rod body that are slidably connected. When the plumb bob 92 moves out of the windproof cylinder 11, the limiting ring 122 upwardly abuts against the plumb bob 92 through the tension spring 126, thereby supporting the plumb bob 92 to prevent the plumb bob 92 from shaking under the influence of strong wind, and preventing the connecting rope 91 from breaking due to excessive shaking amplitude of the plumb bob 92, resulting in potential safety hazards caused by the plumb bob 92 falling.

[0043] Please refer to the appendix Figure 7 , the limiting component 12 further includes a plurality of limiting columns 123. The tops of the limiting columns 123 are fixedly installed on the lower surface of the detection table 7.

[0044] Specifically, the limiting column 123 limits the top end of the plumb bob 92, further improving the stability of the plumb bob 92. The length of the limiting column 123 is less than the length of the connecting rope 91.

[0045] Please refer to the appendix Figure 8 , a support protrusion 124 is arranged directly below the limiting ring 122. The bottom end of the support protrusion 124 is fixedly connected to the upper surface of the base 1. The limiting ring 122 is made of a ferromagnetic material. A magnetic ring 125 is fixedly connected to the upper surface of the support protrusion 124.

[0046] Specifically, the support protrusion 124 is used to raise the height of the magnetic ring 125. When the plumb bob 92 descends into the interior of the windproof cylinder 11, the magnetic ring 125 adsorbs the limiting ring 122, thereby pulling the limiting ring 122 to move downward, enabling the plumb bob 92 to be adjusted by breaking away from the restriction of the limiting ring 122.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
