Description

Technical Field

[0001] This utility model is a verticality calibration device for civil engineering walls, belonging to the field of civil engineering. Background Technology

[0002] Civil engineering, also known as civil construction engineering, is a general term for civil engineering and building engineering. It is an engineering discipline that constructs various facilities and places for human life, production, protection and other activities. It covers buildings and facilities within the scope of engineering projects such as houses, roads, railways, airports, and bridges, including those above ground, underground, on land, on water, and underwater.

[0003] The existing technology has the following problems: In civil engineering, wall verticality calibration devices are often needed, but the existing calibration devices cannot adjust the position between the device and the wall according to the thickness of the building wall. In addition, the existing devices cannot adjust the verticality of the measured part of the wall according to the specific needs during measurement, and the difference in wall verticality measurement cannot be intuitively obtained during measurement.

[0004] In the prior art, application number CN202022499461.1, entitled "A Wall Verticality Calibration Device for Civil Engineering", discloses a wall verticality calibration device for civil engineering, including a shell with a concave structure, a groove fixedly provided on the top surface of the shell, a hook slider slidably connected to the top surface of the groove, and a motor fixedly provided on the upper part of the inner sidewall of the left end face of the shell.

[0005] Although the aforementioned patent can obtain the difference in wall verticality measurement more intuitively based on the wall thickness and distance from the wall, the plumb bob may shake when the line is laid out, which may have a certain impact on the calibration accuracy of verticality. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a verticality calibration device for civil engineering walls.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A civil engineering wall verticality calibration device includes a movable frame and a retractable frame. The retractable frame is vertically slidably connected to the top of the movable frame. A fixed guide rod is fixed on each of the two inner sides of the movable frame. A lifting plate is slidably sleeved between the two fixed guide rods. An inner cavity is opened inside the movable frame. A lifting mechanism that cooperates with the lifting plate is provided in the inner cavity. A level and a mounting frame are provided on the lifting plate. A distance measuring instrument is installed on the bottom side of the mounting frame. A leveling mechanism is provided at the bottom of the movable frame.

[0008] Furthermore, the leveling mechanism includes a mounting cavity formed at the bottom of the movable frame. The bottom of the mounting cavity is connected to the outer surface of the bottom of the movable frame through a movable hole. A lifting cylinder is installed in the mounting cavity. The bottom output end of the lifting cylinder is connected and fixed to a support leg. The support leg slides vertically in the movable hole. The bottom end of the support leg extends movably through to the bottom of the movable frame and is connected to a moving wheel. Several sets of electromagnets that cooperate with the support leg are provided on the inner wall of the movable hole.

[0009] Furthermore, a guide groove is provided on the top of the movable frame, and a guide plate is vertically slidably connected in the guide groove. The top of the guide plate slides through to the top of the movable frame and is connected and fixed to the bottom of the movable frame.

[0010] Furthermore, the lifting mechanism includes support plates installed on both sides inside the inner cavity. A fixed screw is rotatably connected to the support plate. The smooth end of the fixed screw extends through the lower part of the support plate and is connected and fixed to the driven bevel gear. A rotating shaft is rotatably connected between the two support plates. A driving bevel gear is fixed below the two support plates on the rotating shaft. The driving bevel gear meshes with the driven bevel gear. One end of the rotating shaft is connected to the output end of a motor. The motor is fixed on one side of the support plate.

[0011] Furthermore, the threaded end of the fixed lead screw extends movably into the interior of the movable frame, and a nut movable seat that cooperates with the fixed lead screw is fixed on the lifting plate.

[0012] Furthermore, the top ends of both the fixed guide rod and the fixed lead rod extend movably through to the top of the movable frame.

[0013] Furthermore, it also includes a detachable guide rod and a detachable lead rod that are connected and fixed to the fixed guide rod and the fixed lead rod.

[0014] The beneficial effects of this utility model are: Through the design of the leveling mechanism, during use, the equipment is moved to the side of the civil engineering wall, and then leveled by the adjustment mechanism and level. Specifically, the support legs are lowered by the lifting cylinder, and the lowering of the support legs pushes the moving wheels to lower, thus performing the leveling action. The equipment is leveled by adjusting the four sets of support legs one by one. After the support legs are adjusted, several sets of electromagnets in the movable holes are activated. The support legs and the moving frame are magnetically fixed by the electromagnets, thus connecting the support legs and the moving frame into a whole.

[0015] Through the design of the lifting mechanism, during verticality calibration, the motor and rangefinder are started. The motor drives the rotating shaft to rotate, which in turn drives the active bevel gear to rotate. The active bevel gear drives the driven bevel gear to rotate, which in turn drives the fixed screw to rotate, thereby adjusting the lifting plate. During the lifting process, the rangefinder moves vertically, measuring the distance between different positions on the wall and the mounting bracket. By comparing the data measured at various positions on the wall by the rangefinder, it is possible to accurately determine whether the verticality of the wall meets the requirements.

[0016] By using a detachable guide rod and a detachable lead screw, when the height of the wall is higher than the fixed guide rod and the fixed lead screw, the detachable guide rod and the detachable lead screw can be assembled and connected to the top of the fixed guide rod and the fixed lead screw, thereby extending the height of the fixed guide rod and the fixed lead screw, and thus extending the detection height of the rangefinder.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution for a civil engineering wall verticality calibration device, including a movable frame 1 and a mobile frame 2. The mobile frame 2 is vertically slidably connected to the top of the movable frame 1. A fixed guide rod 5 is fixed on each of the two sides inside the movable frame 1. A lifting plate 6 is slidably sleeved between the two fixed guide rods 5. The movable frame 1 has an inner cavity, in which a lifting mechanism that cooperates with the lifting plate 6 is provided. A level 16 and a mounting frame 14 are provided on the lifting plate 6. A rangefinder 15 is installed on the bottom side of the mounting frame 14. A leveling mechanism is provided at the bottom of the movable frame 1. Through the design of the leveling mechanism and the lifting mechanism, the device can be leveled by the leveling mechanism, and the rangefinder 15 can be stably driven to move vertically up and down by the lifting mechanism, thereby performing wall verticality calibration.

[0022] See Figure 4 The leveling mechanism includes a mounting cavity at the bottom of the movable frame 1. The bottom of the mounting cavity is connected to the outer surface of the bottom of the movable frame 1 through a movable hole 18. A lifting cylinder 21 is installed in the mounting cavity. The bottom output end of the lifting cylinder 21 is connected and fixed to a support leg 19. The support leg 19 slides vertically in the movable hole 18. The bottom end of the support leg 19 extends through to the bottom of the movable frame 1 and is connected to a moving wheel 17. Several sets of electromagnets 20 are provided on the inner wall of the movable hole 18 to cooperate with the support leg 19. A guide groove 4 is provided at the top of the movable frame 1. A guide plate 3 is vertically slidably connected in the guide groove 4. The top of the 3 slides through to the top of the movable frame 1 and is connected and fixed to the bottom of the movable frame 2; through the design of the leveling mechanism, when in use, the equipment is moved to the side of the civil engineering wall, and then the equipment is leveled by the adjustment mechanism and the level 16. That is, the support leg 19 is pushed down by the lifting cylinder 21, and the support leg 19 pushes the moving wheel 17 down to perform the leveling action. The equipment is leveled by adjusting the four sets of support legs 19 one by one. After the support leg 19 is adjusted, several sets of electromagnets 20 in the movable hole 18 are activated. The support leg 19 and the movable frame 1 are magnetically fixed by the several sets of electromagnets 20, and then the support leg 19 and the movable frame 1 are connected into a whole.

[0023] See Figures 1-3The lifting mechanism includes support plates 8 installed on both sides of the inner cavity. A fixed screw 9 is rotatably connected to the support plate 8. The smooth end of the fixed screw 9 extends through the lower part of the support plate 8 and is connected and fixed to the driven bevel gear 10. A rotating shaft 11 is rotatably connected between the two support plates 8. A driving bevel gear 12 is fixed below the two support plates 8 on the rotating shaft 11. The driving bevel gear 12 meshes with the driven bevel gear 10. One end of the rotating shaft 11 is connected to the output end of a motor 13. The motor 13 is fixed on one side of the support plate 8. The threaded end of the fixed screw 9 extends through the interior of the movable frame 1. A nut that cooperates with the fixed screw 9 is fixed on the lifting plate 6. The top ends of both the fixed guide rod 5 and the fixed lead screw 9 extend movably through to the top of the movable frame 2. Through the design of the lifting mechanism, during verticality calibration, the motor 13 and the rangefinder 15 are started. The motor 13 drives the rotating shaft 11 to rotate, which in turn drives the active bevel gear 12 to rotate. The active bevel gear 12 drives the driven bevel gear 10 to rotate, which in turn drives the fixed lead screw 9 to rotate, thereby adjusting the lifting plate 6. During the lifting process of the lifting plate 6, the rangefinder 15 moves vertically, measuring the distance between different positions on the wall and the mounting frame 14. Then, by comparing the data measured at various positions on the wall by the rangefinder 15, the verticality of the wall can be accurately determined to meet the requirements.

[0024] See Figure 2 It also includes a detachable guide rod 22 and a detachable lead rod 23 that are connected and fixed to the fixed guide rod 5 and the fixed lead rod 9. Through the design of the detachable guide rod 22 and the detachable lead rod 23, when the height of the wall is higher than the fixed guide rod 5 and the fixed lead rod 9, the detachable guide rod 22 and the detachable lead rod 23 are assembled and connected to the top of the fixed guide rod 5 and the fixed lead rod 9, thereby extending the height of the fixed guide rod 5 and the fixed lead rod 9, and thus extending the detection height of the rangefinder 15.

[0025] In use, the equipment is moved to the side of the civil engineering wall, and then leveled using the adjustment mechanism and level 16. Specifically, the lifting cylinder 21 pushes the support legs 19 down, which in turn pushes the moving wheels 17 down to perform the leveling action. The equipment is leveled by adjusting each of the four sets of support legs 19 one by one. After the support legs 19 are adjusted, several sets of electromagnets 20 in the movable holes 18 are activated. These electromagnets magnetically fix the support legs 19 and the moving frame 1 together, thus connecting them into a single unit. Then, the motor is started. The motor 13 and the rangefinder 15 drive the rotating shaft 11 to rotate, which in turn drives the active bevel gear 12 to rotate. The active bevel gear 12 drives the driven bevel gear 10 to rotate, which in turn drives the fixed screw 9 to rotate, thereby adjusting the lifting plate 6. During the lifting process, the rangefinder 15 moves vertically, measuring the distance between different positions on the wall and the mounting bracket 14. By comparing the data measured at various positions on the wall by the rangefinder 15, the verticality of the wall can be accurately determined to meet the requirements.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
