The weight of each brick can be evenly stacked on it without tilting. In this way, the stability and bearing capacity of the wall will be better, and naturally its wind and earthquake resistance will be better.

[0017] With the above structure, the present invention has the following advantages:

[0018] 1. Through the combination of the hydraulic push assembly and the protractor, the verticality of the wall can be accurately measured. When the wall is tilted, the angle change of the rotating rod will push the piston plate through the hydraulic oil, and then drive the pointer on the protractor to indicate the inclination of the wall.

[0019] 2. When the measuring mechanism detects different positions of the wall, the device sets the pointer and the protractor on the top of the column. The position will not move during measurement. The operator only needs to observe the position of the pointer, and the reading is more accurate and more convenient. After the measuring rod is away from the wall, the elastic force of the second spring can push the piston plate to reset, that is, push the hydraulic oil into the second piston cylinder, push the push rod to move upward, and the push rod abuts against the side wall of the V-shaped groove, so that the rotating rod can be flipped and reset to the vertical state.

[0020] 3. When the device is in use, the operator drives the second conical tooth to rotate by turning the hand wheel, thereby rotating the first conical tooth meshing with the second conical tooth, and then the threaded rod rotates, driving the first slider to slide upward or downward in the slide groove, thereby realizing the up and down sliding of the lifting rod. The measuring mechanism can be used to measure different positions of the wall.

[0021] 4. The present invention not only has the function of measuring the verticality of the wall, but also integrates the function of cleaning the wall surface, realizing the integration of detection and cleaning, and improving work efficiency and practicality. When cleaning the wall surface, the lifting rod slides up and down along the column, the fourth gear meshes with the rack, and the fourth gear will rotate. Through the cooperation of the two second transmission wheels and the second transmission belt, the third gear on the upper side will be driven to rotate synchronously, that is, the second gear will be driven to rotate. In this way, by utilizing the up and down movement of the lifting rod, the cleaning roller can be driven to rotate, and the wall surface can be cleaned without additional power, and the structural design is reasonable.

[0035] like Figure 4 As shown, a protractor 3 is fixed to the upper end of the column 11, a sleeve 31 is rotatably mounted on the back of the protractor 3, a pointer 32 is arranged on the scale side of the protractor 3, and the pointer 32 is fixedly connected to the sleeve 31. A first piston cylinder 33 is fixed to the upper end of the column 11, the first piston cylinder 33 is coaxially arranged with the sleeve 31, a piston plate 34 is sealed and slidably mounted in the first piston cylinder 33, a piston rod 35 is arranged in the oil rod cavity at one end of the piston plate 34 facing the sleeve 31, one end of the piston rod 35 is connected to the piston plate 34, and the other end is slidably connected to the sleeve 31. Specifically, a spiral guide groove 36 is opened on the inner wall of the sleeve 31, and the piston rod 35 extends out of the first piston One end of the cylinder 33 is arranged in the sleeve 31 and a second slider 37 is fixed thereon. The second slider 37 is slidably installed in the spiral guide groove 36. The second slider 37 moves in the spiral guide groove 36 through the axial movement of the piston rod 35, thereby promoting the positive and negative rotation of the sleeve 31. A second spring 341 is sleeved on the piston rod 35 in the first piston cylinder 33. One end of the second spring 341 is fixed on the first piston cylinder, and the other end is fixed on the piston plate 34. The rotating rod 23 is connected to the rodless cavity of the first piston cylinder 33 through a hydraulic pushing component. The rotation angle of the rotating rod 23 around the fixed axis 22 controls the axial movement of the piston rod 35.

[0036] like Figure 8 As shown, the hydraulic push assembly includes an oil passage 226 that is arranged in the middle of the fixed shaft 22 and the middle of the sliding rod 2 and is connected to each other. The oil passage 226 is communicated with the rodless chamber of the second piston cylinder 221 through a hose 227. A second piston cylinder 221 is arranged on the outer side of the fixed shaft 22. The central axis of the second piston cylinder 221 is perpendicular to the central axis of the fixed shaft 22. A sealing plate 222 is sealed and slidably assembled in the second piston cylinder 221. A push rod 223 is fixedly connected to the upper end of the sealing plate 222. The rodless chamber of the second piston cylinder 221 is communicated with the rodless chamber of the first piston cylinder 33 through the oil passage in the middle of the fixed shaft 22, the oil passage in the middle of the sliding rod 2, and the hose 227 in sequence. The first piston cylinder 33 and the second piston cylinder 221 store Hydraulic oil, a circular ring 224 coaxially arranged with the fixed shaft 22 is fixed outside the rotating rod 23 and outside the fixed shaft 22, and a V-shaped groove 225 is provided on the upper side of the inner wall of the center hole of the circular ring 224, and the top of the push rod 223 is in sliding contact with the inner wall of the center hole. Furthermore, a roller can also be provided on the top of the push rod 223, and the roller is in rolling contact with the inner wall of the center hole of the circular ring 224, thereby reducing the influence of friction; in the initial state, the top of the push rod 223 is in contact with the side wall of the V-shaped groove 225 farthest from the center of the fixed shaft 22. In the working state, when the rotating rod 23 rotates, the circular ring 224 is driven to rotate, so that the push rod 223 slides on the inner wall of the circular ring 224, thereby realizing the radial movement of the push rod 223.

[0037] In this embodiment, the top rod 223 is located in the middle of the V-shaped groove 225, and the rotating rod 23 is in a vertical state;

[0038] When measuring a building wall, the control device moves toward the wall until the upper and lower measuring rods 24 abut against the wall, pushing the slide bar 2 to slide a short distance in the through hole, so that the first spring 211 is compressed. The resilience of the first spring 211 can ensure that the measuring rod 24 always abuts against the wall. If the wall is in a vertical state, the relative positions of the two measuring rods 24 will not change, and the rotating rod 23 will not rotate. The lifting rod 12 slides up and down in the column 11 to measure the verticality of the entire wall. If the wall has a certain deflection during the measurement process, one of the two measuring rods 24 will abut against the wall first, which will push the rotating rod 23 to rotate until the other measuring rod 24 abuts against the wall. When the rotating rod 23 rotates, it will drive the ring 224 to rotate relative to the fixed shaft 22 , the side wall of the V-shaped groove 225 will abut against the push rod 223, pushing the push rod 223 to move radially, then the sealing plate 222 moves inwardly in the second piston cylinder 221, and the hydraulic oil in the second piston cylinder 221 is pushed into the first piston cylinder 33 through the oil passage 226 and the hose 227, and the piston plate 34 in the first piston cylinder 33 drives the piston rod 35 to slide inside the sleeve 31, and the second slider 37 slides in the spiral guide groove 36, which can drive the sleeve 31 to rotate, and then drive the pointer 32 to rotate relative to the protractor 3. With this design, if the wall is deflected, the angle of the rotating rod 23 will be deflected, and the hydraulic oil is used as a medium to transmit the deflection of the rotating rod 23 to the pointer 32, so that the pointer 32 indicates the change of the value of the protractor 3, and the value displayed by the protractor 3 is the inclination of the wall;

[0039] When the measuring mechanism detects different positions of the wall, the present design sets the pointer 32 and the protractor 3 at the top of the column 11, and the position thereof will not move during measurement. The operator only needs to observe the position of the pointer 32, and the reading is more accurate and more convenient.

[0040] After the measuring rod 24 is away from the wall, the elastic force of the second spring 341 can push the piston plate 34 to reset, that is, push the hydraulic oil into the second piston cylinder 221, push the push rod 223 to move upward, and through the abutment between the push rod 223 and the side wall of the V-shaped groove 225, the rotating rod 23 can be flipped and reset to a vertical state.

[0041] like Figure 3As shown, a vertically arranged slide groove 111 is opened in the middle of the column 11, and the lifting rod 12 is installed in the slide groove 111 through the first slider 112. A vertically arranged threaded rod 113 is rotatably installed in the slide groove 111. The first slider 112 is threadedly connected with the threaded rod 113. A first conical tooth 114 is fixed to the upper end of the threaded rod 113. A second conical tooth 115 meshing with the first conical tooth 114 is rotatably installed on the side wall of the slide groove 111. A hand wheel 116 is rotatably installed on the right side of the column 11, and the hand wheel 116 is coaxially connected with the second conical tooth 115.

[0042] The operator rotates the hand wheel 116 to drive the second conical tooth 115 to rotate, thereby rotating the first conical tooth 114 meshing therewith, and then the threaded rod 113 rotates, driving the first slider 112 to slide upward or downward in the slide groove 111, thereby realizing the up and down sliding of the lifting rod 12. The measuring mechanism can be used to measure different positions of the wall.

[0043] A counterweight is sleeved in the middle of the hose 227, and the counterweight is located in the slide slot 111; by applying gravity to the hose 227 through the counterweight, the hose 227 can be kept in a vertical state, preventing the hose 227 from being scattered outside the device.

[0044] like Figure 2 , 3 As shown in , 7, as an improvement of the previous embodiment, the two measuring rods 24 are coaxially provided with movable grooves, and L-shaped rods 41 are slidably provided in the two movable grooves. The L-shaped rod 41 includes a horizontal section and a vertical section. The horizontal section of the L-shaped rod 41 is slidably installed in the movable groove, and the vertical section of the L-shaped rod 41 extends from the side of the rotating rod 23 away from the measuring rod 24. An opening connected to the movable groove is provided on the opposite side of the two measuring rods 24. A cleaning roller 42 is vertically arranged between the two measuring rods 24, and both ends of the cleaning roller 42 pass through the measuring rods 24. The opening on the upper part is rotatably assembled on the horizontal section of the L-shaped rod 41, and the vertical section of the L-shaped rod 41 is connected to the rotating rod 23 by a third spring 43. The vertical section end of the L-shaped rod 41 is rotatably assembled with a first gear 44. A transmission assembly is provided in the L-shaped rod 41, and the transmission assembly connects the first gear 44 with the cleaning roller 42. The cleaning roller 42 can be driven to rotate by driving the first gear 44; the upper side of the lifting rod 12 is rotatably assembled with a second gear 5 that matches the position of the first gear 44, and the second gear 5 is driven to rotate by the rotating assembly.

[0045] like Figure 6As shown, further, the transmission assembly includes a first cavity opened in the horizontal section of the L-shaped rod 41, and the first transmission wheel 411 and the second transmission wheel are respectively rotatably mounted at both ends of the first cavity, the first transmission wheel 411 and the second transmission wheel are connected by a first transmission belt, the cleaning roller 42 is connected by a transmission connection with the second transmission wheel, and the first gear 44 is connected by a transmission rod with the first transmission wheel 411; when the first gear 44 rotates, the right first transmission wheel 411 can be driven to rotate through the transmission rod, and then the left first transmission wheel 411 can be driven to rotate synchronously through the first transmission belt, so that the cleaning roller 42 rotates. A plurality of scrapers are fixed on the side wall of the cleaning roller 42; the soil and mud blocks of the wall are cleaned by the scrapers, and the cleaning effect is better.

[0046] The rotating assembly includes a second cavity provided in the middle of the lifting rod 12, and second transmission wheels 51 are rotatably mounted at both ends of the second cavity. The lifting rod 12 is rotatably mounted with a third gear 52 meshing with the second gear 5. The two second transmission wheels 51 are connected by a second transmission belt, and the third gear 52 is coaxially connected with the second transmission wheel 51. A fourth gear 53 is rotatably mounted on the lower side of the lifting rod 12, and the fourth gear 53 is coaxially connected with the second transmission wheel 51. A rack 54 meshing with the fourth gear 53 is fixed to the side wall of the column 11. When cleaning the wall surface, the lifting rod 12 slides up and down along the column 11, and the fourth gear 53 meshes with the rack 54. The fourth gear 53 will rotate, and the cooperation of the two second transmission wheels 51 and the second transmission belt will drive the third gear 52 on the upper side to rotate synchronously, that is, drive the second gear 5 to rotate, so that by utilizing the up and down movement of the lifting rod 12, the cleaning roller 42 can be driven to rotate, and the wall surface is cleaned without additional power, and the structural design is reasonable.

[0047] like Figure 5 , 7 As shown, a guide groove 45 is provided on the side wall of the slide bar 2, and a fixing block 46 matching the guide groove 45 is fixed in the through hole of the column 11. After the slide bar 2 is installed in the through hole, the fixing block 46 is slidably transferred to the guide groove 45. The guide groove 45 is composed of a first transverse groove 451, a second spiral groove 452 and a second transverse groove 453 which are interconnected and arranged from one end of the slide bar 2 to the other end. The first transverse groove 451 and the second transverse groove 453 are both arranged along the axial direction of the slide bar 2, and the second spiral groove 452 connects the first transverse groove 451 and the second transverse groove 453. The first transverse groove 451 and the second transverse groove 453 are staggered 90 degrees in the circumferential direction. A pulling ring 461 is installed at the end of the slide bar 2 away from the rotating rod 23. A locking assembly which can lock the axial movement position of the slide bar 2 is also provided between the slide bar 2 and the lifting rod 12. When the slide bar 2 slides, the fixing block 46 slides in the guide groove 45 for guidance, which can drive the slide bar 2 to rotate ninety degrees.

[0048] like Figure 5As shown, further, the locking assembly includes an installation cavity 47 opened on the upper side of the lifting rod 12 and connected to the through hole of the column 11, a pulling block 471 is installed in the installation cavity 47, one end of the pulling block 471 extends from the top of the lifting rod 12 to form a handle, a slider is installed in the middle of the pulling block 471, and a locking block 473 is formed at the bottom of the pulling block. The locking block 473 can extend from the installation cavity 47 and be inserted into the through hole of the column 11. The pulling block 471 is slidably installed in the installation cavity 47 through the slider in the middle, and the upper side of the slider of the pulling block 471 is connected to the top wall of the installation cavity 47 through a fourth spring 472, and the slide bar 2 is provided with a locking groove matching the locking block 473;

[0049] In the initial state, the fixed block 46 is located in the first transverse groove 451 to limit the slide bar 2. Under the push of the elastic force of the third spring 43, the cleaning roller 42 between the two L-shaped rods 41 is located close to the rotating rod 23. When measuring the wall, the measuring rod 24 abuts against the wall, pushing the slide bar 2 to slide a short distance in the through hole. At this time, the fixed block 46 still slides in the first transverse groove 451, and the slide bar 2 as a whole only slides horizontally. The elastic force of the first spring 211 is used to keep the measuring rod 24 in contact with the wall at all times.

[0050] If there are clods of soil and mud on the wall, the detection results will be affected and they need to be cleaned. The operator first rotates the pull ring 461 to pull the slide bar 2 to slide to the right, so that the fixed block 46 enters the second spiral groove 452 from the first transverse groove 451, and then enters the second transverse groove 453. In this way, the slide bar 2 rotates itself ninety degrees during the horizontal rightward sliding process; when the fixed block 46 just enters the second transverse groove 453, Fig. 9 As shown, at this time, the L-shaped rod 41 has been turned over and is in a horizontal state. The first gear 44 connected at the end will be in the same horizontal plane with the second gear 5, and the fixed block 46 continues to move along the second transverse groove 453. The L-shaped rod 41 slides horizontally to the right. After the first gear 44 and the second gear 5 are in contact and meshed, the rotating rod 23 continues to be pulled to the right as a whole. At this time, the L-shaped rod 41 will slide to the left as a whole relative to the rotating rod 23, pushing the cleaning roller 42 to move along the opening on the measuring rod 24 to the side away from the rotating rod 23, so that the cleaning roller 42 extends out of the end of the measuring rod 24. At this time, the fixed block 46 will be at the end of the second transverse groove 453, as shown in FIG. Fig. 9 As shown, the rotating rod 23, the L-shaped rod 41 and the cleaning roller 42 are all in a horizontal state, at which time the first gear 44 is meshed with the second gear 5, and the cleaning roller 42 is at the end of the measuring rod 24. At this time, the position of the slide bar 2 is fixed by the locking assembly, and the device can maintain this state;

[0051] In this way, the operator can make the cleaning roller 42 contact with the wall in the above state, drive the second gear 5 to rotate through the rotating component, and then transmit power to the first gear 44, and drive the power to be transmitted to the cleaning roller 42 through the transmission component. The rotating cleaning roller 42 contacts the wall, and can clean the soil and mud on its surface to prevent affecting the detection accuracy.

[0052] The end of the hose 227 and the slide bar 2 may be rotatably connected, and the rotation of the slide bar 2 will not drive the hose 227 to rotate synchronously.

[0053] When the fixing block 46 moves to the end of the second transverse groove 453, the rotating rod 23, the L-shaped rod 41 and the cleaning roller 42 are all in a horizontal state, and the locking groove on the slide bar 2 is aligned with the locking block 473, and the locking block 473 is pushed into the locking groove by the elastic force of the fourth spring 472, thereby fixing the slide bar 2. When the device is restored to the measuring state, it is only necessary to pull the pulling block 471 upwards, and the locking block 473 is pushed out of the locking groove. The slide bar 2 is reset under the elastic force of the first spring 211, and the rotating rod 23 and the L-shaped rod 41 are restored to the vertical state as a whole.

[0054] The present application can realize the transformation of the overall state of the rotating rod 23 and the measuring rod 24 as needed, so as to achieve the function of measuring or cleaning the wall, and is more practical.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
