This design is easy to install and disassemble, and has a high recycling rate. During the construction process, the lattice columns are usually hoisted into the foundation pit by a crane. In order to ensure the construction quality, the lattice columns need to be kept in a vertical arrangement.

[0003] In the prior art, a ruler is often used to measure the verticality of the lattice column after the lattice column is installed. Due to the limited accuracy of the ruler itself, it cannot accurately measure errors of smaller angles. Moreover, the ruler can only determine whether the object to be measured is straight, but cannot measure the actual offset angle, which is not conducive to subsequent correction. Summary of the invention

[0010] Furthermore, a backup ring is installed on the outer circumferential surface of the measuring tube, and the structure of the backup ring is the same as that of the basic ring.

[0011] Furthermore, the adjustment ring is a square ring.

Through the position of the laser on the display mark, it is possible to obtain whether the laser is vertical and the degree of deflection of the straight tube, and then the degree of deflection of the lattice column in the vertical direction can be known, so as to facilitate the adjustment of the lattice column, thereby solving the problem that the error caused by relying on a ruler to detect the verticality of the lattice column in the prior art is large, and smaller offset angles cannot be accurately measured.

[0029] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0030] In the embodiment 1 of the laser-based lattice column verticality detection device (hereinafter referred to as the detection device) of the present invention:

[0031] The detection device in the present invention includes a mounting bracket and a measuring tube that can move relative to each other. The connection position between the measuring tube and the mounting bracket is located on the upper side of the center of gravity of the measuring tube, so that the measuring tube can move freely relative to the mounting bracket under the action of gravity and automatically maintain a vertical state. Afterwards, the laser path is measured using the laser inlet and display mark on the measuring tube. When the laser transmitter is installed on the lattice column, the orientation of the lattice column can naturally be displayed.

[0032] Specifically, Figure 1 and Figure 4As shown, the detection device in the present invention includes a measuring tube 1, which is a transparent glass tube with one end open and the other end closed. The glass tube is cylindrical and can hold liquid. When in use, the end of the measuring tube 1 with the opening is arranged upward. A base ring 11 is arranged on the outer circumference of the glass tube. The base ring 11 is located at one-third of the distance from the tube mouth of the transparent glass tube. The base ring 11 includes a ring body fixedly connected to the outer circumference of the glass tube and in a circular shape and a first connecting shaft 111 located on the ring body. The first connecting shaft 111 has two first connecting shafts 111 located on both sides of the ring body, and the axes of the two first connecting shafts 111 are collinear, so that the measuring tube 1 can rotate along the axis of the first connecting shaft 111. Of course, in other embodiments, the measuring tube can also be a square tube, and the ring body of the base ring should also be adaptively adjusted to a square ring. Alternatively, in other embodiments, the first connecting shaft can also be directly set on the glass tube during the manufacturing process. Alternatively, in other embodiments, the measuring tube can also be an acrylic tube for convenient observation of the laser. Alternatively, in other embodiments, the measuring tube may also be a transparent glass tube with both ends sealed, in which case the tube may be filled with liquid or remain empty.

[0033] The outer periphery of the base ring 11 is also hingedly connected with an adjustment ring 2. Specifically, the first connecting shaft 111 is installed on the adjustment ring 2. The adjustment ring 2 includes a square ring body and two second connecting shafts 21 located on both sides thereof. The axes of the two second connecting shafts 21 are collinear, and the axes of the second connecting shafts 21 and the first connecting shaft 111 are perpendicular to each other and located in the same plane. A mounting bracket 3 is also provided on the outer side of the adjustment ring 2, and the second connecting shaft 21 is installed on the mounting bracket 3. In this way, during the adjustment process, the measuring tube 1 has rotational freedom in two directions relative to the mounting bracket 3, which facilitates the automatic adjustment of the measuring tube 1. And because the base ring 11 is located on the upper side of the center of gravity of the measuring tube 1, the first connecting shaft 111 and the second connecting shaft 21 are respectively located on the upper side of the center of gravity of the measuring tube 1. When in use, the measuring tube 1 will tend to be in a vertical downward state under the action of gravity. Of course, in other embodiments, the adjustment ring can also be set to other shapes.

[0034] In order to measure the verticality, a laser transmitter is provided for installation on the part to be detected. In this embodiment, the lattice column is measured, so the part to be detected is the lattice column. Of course, if other objects are to be detected, the laser transmitter can also be adaptively installed on other objects. Figure 2 and Figure 3As shown, in order to display the laser, a bottom end cap 13 is provided at the bottom of the measuring tube 1, and the center of the bottom end cap 13 is provided with the laser entrance 131, thereby ensuring that only one laser enters. A top cover plate 14 is installed on the top of the measuring tube 1, and a display mark 141 is provided on the top cover plate 14 to conveniently display the landing point of the laser at the top. In this embodiment, the laser propagates from bottom to top. Of course, if in other embodiments, the laser emitter emits the laser downward, the positions of the top cover plate 14 and the bottom end cap 13 can also be swapped to ensure that the laser entrance 131 is placed close to the laser emitter. The display mark 141 is a plurality of circular scale lines with different diameters arranged at intervals and the center of the circle is located on the axis of the measuring tube 1. In addition, a cross-shaped coordinate axis is provided, and a scale is displayed on the coordinate axis, so that the degree of deflection of the laser can be conveniently and intuitively read. Of course, in other embodiments, the display mark can also be set to other forms, such as only a coordinate axis, and no longer a circular ring.

[0035] In addition, since it is uncertain whether the laser emitter is located on the upper or lower side of the measuring tube, in other embodiments, the bottom end cap with the laser inlet may face upward, and the top end cap with the display mark may face downward. In order to facilitate the adjustment of the up and down direction of the measuring tube, a backup ring 12 with the same structure as the basic ring 11 is also provided on the outer circumference of the measuring tube 1. The backup ring is located at a position close to two-thirds of the tube mouth. When the backup ring 12 is installed on the adjustment ring 2, the direction of the measuring tube can naturally be changed.

[0036] In order to facilitate the laser visualization, a visualization liquid for laser visualization is also provided in the measuring tube 1. In this embodiment, the visualization liquid is red ink. Of course, in other embodiments, it can also be replaced with an ion solution or food coloring solution that can display the laser path. In addition, the measuring tube 1 filled with the visualization liquid is heavier, and the torque during rotation is greater, which is convenient for maintaining the vertical state of the measuring tube 1. The detection device is usually set up in the open air. Under the erosion of rainwater, rust may occur at the first connecting shaft 111 and the second connecting shaft 21. By setting the visualization liquid, the torque during rotation can also be increased, which is convenient for overcoming friction and rotation. If it is necessary to use the spare ring 12 to reverse the measuring tube 1, the measuring tube can be set as a glass tube with closed ends. At this time, even if the direction is reversed, the visualization liquid will not spill out.

[0037] In an embodiment of the method for installing a lattice column of the present invention:

[0038] In this embodiment, the above-mentioned laser-based verticality detection device is used. During the installation of the lattice column, a laser emitter is first installed at the top of the lattice column, and the position of the laser emitter relative to the lattice column is adjustable. During installation, it is necessary to keep the light emitted by the laser emitter consistent with the direction of the lattice column. Specifically, the lattice column can be placed on the ground during installation. At this time, the natural lattice column is parallel to the ground. Then the laser emitter is allowed to emit a laser. The emission port of the laser emitter is at a determined height from the ground. If the distance between the laser and the ground is the same after a certain distance, it means that the laser is parallel to the ground. A baffle is placed on the travel path of the laser of the laser emitter, and the height of the point where the laser is located on the baffle and the ground is measured. If the height of the point where the laser is located and the ground is the same as the height of the emission port of the laser emitter from the ground, it means that the laser emitted by the laser emitter is parallel to the lattice column, which is convenient for subsequent use.

[0039] like Figure 5 As shown, before the installation of the lattice column, a construction frame is usually built at the construction site, and the construction frame has a certain height. In order to detect the verticality of the lattice column, a parallel connecting rod 41 is also provided between the two construction frames, and the mounting bracket 3 is placed on the connecting rod 41. The two connecting rods 41 are arranged in parallel, so that it is convenient to set the mounting bracket 3 at any position of the connecting rod 41. During installation, it is necessary to pay attention to setting the mounting bracket 3 roughly above the installation position of the lattice column, and then lower the lattice column. During the lowering process, especially during the pile hole of the lattice column, in order to avoid finding that the lattice column is skewed after the construction is completed, it is necessary to observe the posture of the lattice column more. During the detection process, the position of the mounting bracket 3 is adjusted, and then the measuring tube 1 is driven to adjust its position, so that the laser can enter the measuring tube 1 through the laser inlet 131, so as to know the degree of deflection of the lattice column, which is convenient for adjustment before solidification.

[0040] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
