[0002] In the field of construction surveying, the vertical transfer measurement of the axis is mainly divided into two control measurement methods, namely external control method and internal control method.

[0003] Currently, the primary method for measuring the vertical alignment of a building's axis is internal control, typically using a laser plumb line projection method. This method addresses most of the drawbacks of the plumb line method, which suffers from the lack of accuracy and the theodolite zenith method, which requires additional accessories and is inconvenient to operate. However, the laser receiving target must be placed on a concrete slab, making precise movement and alignment difficult. Furthermore, after receiving the light spot, the laser receiver itself is difficult to secure to the floor. Utility Model Content

[0004] The purpose of the utility model is to provide a floor layout auxiliary tool with an adjustable frame height and a movable laser receiving target. By installing the laser receiving target on a movable and height-adjustable auxiliary tool, the problem of the inconvenience of moving the laser receiving target during the existing layout process is solved, and the problem of inaccurate alignment caused by the unevenness of the ground itself is also solved.

[0005] To achieve the above-mentioned purpose, the utility model provides a floor layout auxiliary tool with adjustable frame height and movable laser receiving target, comprising multiple sets of telescopic rods, each set of which is fixed with a positioning foot at the bottom end;

[0006] A plurality of connecting frames are horizontally arranged at the top of the telescopic rod, and a connecting shaft is sleeved between each two connecting frames, and the telescopic rod is rotatably connected to the connecting frame through the connecting shaft;

[0007] A pan head is horizontally arranged on the connecting frame, and the pan head is fixedly connected to the connecting frame.

[0008] Furthermore, the telescopic rod includes an outer rod and an inner rod matching the outer rod, and the inner rod is sleeved in the outer rod;

[0009] The top end of the outer rod is provided with a connecting hole matching the connecting shaft.

[0010] Furthermore, an adjusting screw is provided on the outer rod, and the adjusting screw passes through the outer rod and abuts against the inner rod.

[0011] Furthermore, the positioning foot is a cone with the tip facing downwards;

[0012] The upper end of the positioning foot is threadedly connected to the inner rod.

[0013] Furthermore, a fixing screw is provided on the connecting frame, and the connecting frame is fixedly connected to the pan / tilt head via the fixing screw.

[0014] Furthermore, a leveling device is provided on the upper end surface of the pan / tilt platform, and the leveling device is arranged horizontally.

[0015] Furthermore, a plurality of magnets are horizontally arranged on the upper end surface of the pan / tilt head.

[0016] Compared with existing equipment, this utility model has the following benefits:

[0017] 1. The laser receiving target is placed on a height-adjustable and movable frame. When performing the spot receiving alignment work, it is easier to move and align, and the alignment accuracy is higher.

[0030] Example 1

[0031] This embodiment provides Figures 1 to 3 The illustrated floor-laying auxiliary tool with adjustable frame height and movable laser receiving target comprises a plurality of telescopic rods 1, the bottom end of each telescopic rod 1 being fixed with a positioning foot 2, the telescopic rod 1 being the bottom support structure of the line-laying auxiliary tool, and the telescopic structure design can effectively solve the problem of inaccurate alignment that may occur when the laser receiving target is placed on the ground, and also solves the problem of obstruction by working layer materials that may occur on site. Preferably, three groups of telescopic rods 1 are installed, and the bottom of the telescopic rods 1 is provided with matching positioning feet 2 for positioning and playing a role of fixed support. The three positioning feet 2 form an equilateral triangle structure after the telescopic rods 1 are stretched out, which provides better support and positioning effect for the entire line-laying auxiliary tool;

[0032] Specifically, three connecting frames 3 are horizontally arranged at the top of the telescopic rod 1. The connecting frames 3 are triangular-shaped plates. A connecting shaft 4 is sleeved between each two connecting frames 3. The telescopic rod 1 is rotatably connected to the connecting frames 3 through the connecting shaft 4.

[0033] A pan head 5 is horizontally arranged on the connecting frame 3, and the pan head 5 is fixedly connected to the connecting frame 3;

[0034] The line-laying auxiliary tool is composed of a pan-tilt head 5, a connecting frame 3 and a telescopic rod 1. The pan-tilt head 5 is the top component of the line-laying auxiliary tool, serving as a carrying platform for the laser receiving target. The telescopic rod 1 is the final supporting structure of the line-laying auxiliary tool. It is also designed as a lifting structure to adapt to different occasions, or for surveyors of different heights, the height can be freely adjusted to facilitate spot reception. The three connecting frames 3 are fixedly connected together by three connecting shafts 4 to form a connecting frame of the entire line-laying auxiliary tool. The connecting frame connects the pan-tilt head 5 and the telescopic rod 1 together to finally form the entire line-laying auxiliary tool.

[0035] Further, such as Figure 1 and Figure 2 As shown, the telescopic rod 1 includes an outer rod 11 and an inner rod 12 that matches the outer rod 11. The inner rod 12 is sleeved in the outer rod 11. The inner rod 12 is nested in the outer rod 11 and can slide up and down in the outer rod 11, so that the height can be adjusted;

[0036] The top of the outer rod 11 is provided with a connecting hole 111 that matches the connecting shaft 4. The connecting shaft 4 passes through the connecting hole 111 and is fixedly connected to the two connecting frames 3, so that the telescopic rod 1 is connected to the connecting frame 3 and can be rotated. When in different occasions or when the height of the entire line-releasing auxiliary tool needs to be lowered, the three outer rods 11 can be pulled outward to lower the overall height.

[0037] Furthermore, an adjusting screw 6 is provided on the outer rod 11, and the adjusting screw 6 passes through the outer rod 11 and abuts against the inner rod 12. When height adjustment is required, first loosen the screw 6, then extend or push the inner rod 12 to the required height, and then tighten the adjusting screw 6 until it is tight against the inner rod 12.

[0038] Furthermore, the positioning foot 2 serves as the bottom support and positioning structure. The positioning foot 2 is a cone with the tip of the cone facing downward. The tips of the three positioning feet 2 jointly support the ground to effectively prevent the line-laying auxiliary tool from moving after it is placed. The three positioning feet 2 are arranged separately in a triangle when spread out, which further improves the stability of the line-laying auxiliary tool.

[0039] The upper end of the positioning foot 2 is threadedly connected to the inner rod 12. After the positioning foot 2 is damaged, it can be replaced quickly and promptly to prevent the damaged positioning foot 2 from affecting the horizontal accuracy of the line-laying auxiliary tool or causing damage to the equipment due to sliding.

[0040] Furthermore, a plurality of fixing screws 7 are provided on the connecting frame 3, and the fixing screws 7 pass through the connecting frame 3 from bottom to top and are fixedly connected to the pan / tilt head 5;

[0041] The fixing screw 7 further limits and fixes the connection frame.

[0042] Furthermore, the pan-tilt platform 5, as a supporting platform for placing the laser receiving target, requires an accurate horizontal reference. A leveling device 8 is horizontally embedded on the upper end surface of the pan-tilt platform 5. The leveling device 8 is a circular leveler, which can make up for the problem of the small size of the pan-tilt platform 5.

[0043] Further, such as Figure 3 As shown, a plurality of magnets 9 are horizontally arranged on the upper end surface of the pan-tilt head 5 and embedded at the three top corners of the pan-tilt head 5. Specifically, the magnet 9 is a neodymium magnet. The neodymium magnet has the characteristics of strong machinability and high energy density. The neodymium magnet is processed into the shape of a small circular plate so that it can be embedded in the pan-tilt head 5 with a smaller surface area. At the same time, it can also provide sufficient magnetic force to prevent the laser receiving target from moving due to a small force and affecting the reception of the light spot. When in use, a neodymium magnet needs to be placed on the end face of the laser receiving target.

[0044] When in use: place the line-setting auxiliary tool above the line-setting hole. After the laser plumb line in the floor has completed the laser beam projection, place the laser receiving target on the upper end face of the pan-tilt 5 of the line-setting auxiliary tool. Place a neodymium magnet on the end face of the laser receiving target. The neodymium magnet of the laser receiving target is attracted to the magnet 9 of the pan-tilt 5. Fix the laser receiving target on the pan-tilt 5. After fixing the laser receiving target, adjust the overall level of the line-setting auxiliary tool through the telescopic rod 1. After that, complete the horizontal accuracy adjustment of the line-setting auxiliary tool through the leveling device 8. Fix the telescopic rod 1 to make the entire line-setting auxiliary tool stable and immovable.

[0045] Then remove the neodymium magnet of the laser receiving target and move the laser receiving target to receive the laser beam emitted by the laser plumb line. After the laser beam is received, the neodymium magnet of the laser receiving target is attracted to the magnet 9 of the pan-tilt head 5 to fix the laser receiving target and complete the measurement.

[0046] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
