Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to an automatic climbing verticality measuring instrument. Background Technology

[0002] With the widespread adoption of steel structures, more and more buildings are using steel structure construction. However, as prefabricated components, if the installation accuracy does not meet the requirements, subsequent components may not be able to be installed. Therefore, after the steel columns are installed, their verticality needs to be measured and adjusted promptly. However, conventional measurement methods rely on professional surveyors and total stations. Total stations are expensive and cannot be widely deployed, resulting in slow verticality measurement of steel columns. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic climbing verticality measuring instrument, which simplifies the operation process of verticality measurement and improves the measurement accuracy.

[0004] To achieve the above technical effects, this utility model provides an automatic climbing verticality measuring instrument, which includes:

[0005] An automatic crawling device includes two toothed rods magnetically connected to the surface of a component and capable of reciprocating alternately on the surface of the component. A drive mechanism is provided between the two toothed rods for driving the two toothed rods to reciprocate alternately, thereby climbing on the surface of the component.

[0006] A verticality measuring device is fixedly connected to the automatic crawling device. The verticality measuring device includes a power supply, an ammeter, and a sliding rheostat that are electrically connected to each other. A first connecting rod is fixedly connected to the slider of the sliding rheostat, and a gravity ball for contacting the surface of the component is fixedly connected to the end of the first connecting rod opposite to the slider.

[0007] Preferably, electromagnets are fixedly connected to the ends of the two racks that are relatively far apart on one side.

[0008] Preferably, the drive mechanism includes two gears meshing between the tooth surfaces of the two racks and rotating in opposite directions. Each of the two gears is provided with a horizontal moving component for driving the two gears to move horizontally to enter between the tooth surfaces of the two racks, thereby driving the two racks to rise alternately through alternating rotation.

[0009] Preferably, the horizontal moving assembly includes a slide groove connected to the gear via a connecting rod, a flying disc rotatably mounted on one side of the gear, and a second connecting rod disposed between the slide groove and the flying disc. The first end of the second connecting rod is slidably disposed in the slide groove, and the second end is fixedly connected to the flying disc. A motor is coaxially connected to the flying disc for driving the flying disc to rotate around its own axis and causing the first end of the second connecting rod to be displaced in the slide groove, thereby driving the gear to move between the tooth surfaces of the two racks. The rotation direction of the flying disc is perpendicular to the rotation direction of the gear.

[0010] Preferably, a rotating rod is connected between the first connecting rod and the gravity ball, and the rod surface of the rotating rod is in contact with the surface of the component.

[0011] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0012] 1) Used for measuring the verticality of steel columns and steel plate shear walls of various shapes.

[0013] 2) Compared with other measurement methods, it reduces the difficulty of operation and the need for high-precision instruments and professional personnel.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0029] Please see Figures 1 to 9 As shown, this utility model embodiment provides an automatic climbing verticality measuring instrument, including an automatic climbing device and a verticality measuring device fixedly connected to the automatic climbing device. The automatic climbing device includes two toothed rods 1 magnetically connected to the surface of a component and capable of reciprocating alternately on the surface of the component. A driving mechanism is provided between the two toothed rods 1 for driving the two toothed rods 1 to reciprocate alternately, thereby climbing on the surface of the component. The verticality measuring device includes a power supply 5, an ammeter 6, and a sliding rheostat 7 electrically connected to each other. A first connecting rod 8 is fixedly connected to the slider of the sliding rheostat 7. A gravity ball 10 for contacting the surface of the component is fixedly connected to the end of the first connecting rod 8 opposite to the slider.

[0030] Furthermore, electromagnets 2 are fixedly connected to the ends of both racks 1 that are relatively far apart from each other. For example... Figures 4 to 7 As shown, in this embodiment, the automatic crawling device includes a first toothed rod 11 and a second toothed rod 12. A first electromagnet 21 is fixedly connected to one end of the first toothed rod 11 that is relatively far away from the second toothed rod 12, and a second electromagnet 22 is fixedly connected to one end of the second toothed rod 12 that is relatively far away from the first toothed rod 11.

[0031] Furthermore, the drive mechanism includes two gears 3 meshing between the tooth surfaces of two racks 1 and rotating in opposite directions. Each gear 3 is equipped with a horizontal moving assembly 4 for driving the two gears 3 to move horizontally between the tooth surfaces of the two racks 1, thereby alternately rotating and driving the two racks 1 to rise alternately. Figures 4 to 7 As shown, in this embodiment, a first gear 31 and a second gear 32 are meshed between the first rack 11 and the second rack 12. The first gear 31 and the second gear 32 rotate in different directions and are driven by the horizontal moving component 4 to enter or exit the force of the automatic climbing device. Preferably, the horizontal movement component includes a groove 42 connected to the gear 3 via a connecting rod 41, a flying disc 43 rotatably mounted on one side of the gear 3, and a second connecting rod 44 disposed between the groove 42 and the flying disc 43. The first end of the second connecting rod 44 is slidably disposed in the groove 42, and the second end is fixedly connected to the flying disc 43. A motor 45 is coaxially connected to the flying disc 43 to drive the flying disc 43 to rotate around its own axis, thereby causing the first end of the second connecting rod 44 to generate a horizontal displacement in the groove 42, which in turn drives the gear 3 to rotate. The gear 3 enters or leaves the rack 1 through rotation. In this embodiment, the rotation direction of the flying disc is perpendicular to the rotation direction of the gear 3. By considering the size of the flying disc 43 and the length of the second connecting rod 44, the time for the gear 3 to enter and leave is exactly equal to the time for the rack 1 to move one cycle. It should be noted that in this embodiment, the first gear 31 and the second gear 32 are respectively coaxially connected to drive motors that drive their own rotation. The gears 3 are controlled by the horizontal moving component 4. The first rack 11 and the second rack 12 rise alternately under the action of the first gear 31 and the second gear 32. After reaching the specified height, the motor 45 is turned off, the equipment stops running, and it is tightly connected to the surface of the steel component by the attraction of the electromagnet 2.

[0032] Please refer to the following: Figures 1 to 3 As shown, in this embodiment, a rotating rod 9 is connected between the first connecting rod 8 and the gravity ball 10, and the rod surface of the rotating rod 9 is in contact with the surface of the component.

[0033] The working principle of the dynamic climbing verticality measuring instrument according to this utility model embodiment includes:

[0034] In operation, the first electromagnet 21 of the first rack 11 is activated, and the first gear 31 enters the working state. Because the first electromagnet 21 is attracted to the steel component, the first gear 31 rotates counterclockwise, driving the measuring instrument upwards, and simultaneously driving the second rack 12 to move and retract upwards. Figure 4 Entering the state in Figure 6 In state one, the measuring instrument rises to a certain height. At this time, the first gear 31 disengages, and the second gear 32 rotates clockwise. The second electromagnet 22 of the second rack 12 is activated and attracted to the steel component. The second gear 32 rises along the second rack 12, simultaneously driving the first rack 11 to extend upwards. Figure 6 Once the state in is entered Figure 7 In state two, the first gear 31 and the second gear 32 rotate in different directions and are driven by the horizontal moving component 4 to enter or exit the force of the automatic climbing device.

[0035] During measurement, if the perpendicularity of the component is not zero, the rotating rod 9, driven by the gravity ball 10, will move relative to its initial position (e.g., Figure 2 As shown) will rotate (as shown) Figure 3 As shown in the diagram, the slider in the sliding rheostat 7 (whose structure and working principle are publicly known prior art) is moved by the first connecting rod 8, thereby changing the resistance value of the circuit connected to the sliding rheostat 7, which in turn causes a change in the current. The change in current is proportional to the degree of tilt of the component. By using the principle that the change in resistance of the sliding rheostat in the circuit causes a change in current, the rotation of the measuring rod is converted into a change in current, ensuring the accuracy of the measurement. The accurate value of the verticality of the component can be obtained by calculation (and the tilt direction of the component can also be determined). It should be noted that in this embodiment, after the data measurement is completed, the data is stored. The automatic climbing verticality measuring instrument returns to the initial position from the component by the alternating movement of the rack 1, and the verticality measurement of the next component can be performed.

[0036] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
