Technical Field

[0001] The utility model relates to the field of construction, in particular to a construction measurement and positioning device. Background Art

[0002] Construction measurement and positioning refers to the use of various measurement tools and techniques to accurately measure and position buildings or engineering projects during the construction process to ensure that the location, size and elevation of the building meet the design requirements. Construction measurement and positioning devices are equipment used for measurement and positioning at the construction site.

[0003] The existing construction measurement and positioning is carried out by using a laser level, and then the ink line or rope in the ink cartridge is dipped in ink, and then the ink line is pulled out manually, and then the ink line is pulled by people so that the ink line contacts the wall or the ground for marking. The ink line is easily offset when pulled by people, resulting in errors in the measurement points, affecting the accuracy of the construction. At the same time, the ink is easy to stick to the hands of the operator.

[0004] Therefore, it is necessary to design a construction measurement and positioning device that can draw lines on the wall or the ground for measurement and positioning, reduce errors, ensure the accuracy and precision of construction, and prevent ink from sticking to the operator's hands.

The rotating bin is rotatably connected between the lower parts of the lifting frame, the rotating bin is connected to the sponge ring, and the top of the lifting frame is connected to the ink bag.

[0010] Furthermore, the lifting frames are all hollow structures.

[0011] Furthermore, it also includes a tensioning mechanism, which includes a support arm, a rotating frame, a contact wheel and a torsion spring. The support arm is connected to the left side of the upper part of the connecting frame, and the support arm is in contact with the pull rope. The supporting arm is rotatably connected to the rotating frame, and the contact wheels are rotatably connected to the upper and lower sides of the rotating frame, and the contact wheels are in contact with the pull rope. Two front and rear torsion springs are connected between the rotating frame and the support arm.

[0012] The utility model has the following advantages: 1.

DETAILED DESCRIPTION

[0020] The preferred technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0021] A construction measurement and positioning device, such as Figure 1-Figure 4 As shown, it includes a support bin 1, a winding wheel 2, an adjusting screw 4, a pull rope 5, a connecting frame 6 and a marking mechanism 7. The winding wheel 2 is rotatably connected to the support bin 1, and also includes a crank 3. The crank 3 is provided on the upper side of the middle of the winding wheel 2. The adjusting screw 4 is threadedly connected to the left side of the upper part of the support bin 1. The adjusting screw 4 is in contact with the winding wheel 2. Two upper and lower pull ropes 5 are wound around the winding wheel 2. A connecting frame 6 is connected between the right sides of the pull ropes 5. A handle is provided on the upper right side of the connecting frame 6. A marking mechanism 7 for marking lines during construction is provided on the pull rope 5.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the marking mechanism 7 includes a support frame 71, a support wheel 72, a lifting frame 73, a rotating bin 74, a sponge ring 75 and an ink bag 76. The support frame 71 is slidably connected to the pull rope 5. The upper and lower sides of the support frame 71 are rotatably connected to the upper and lower support wheels 72. The support wheels 72 are in contact with the pull rope 5. The front and rear sides of the support frame 71 are slidably connected to the lifting frames 73. The lifting frames 73 are all hollow structures. The rotating bin 74 is rotatably connected between the lower parts of the lifting frames 73. The rotating bin 74 is connected to the sponge ring 75, and the top of the lifting frames 73 is connected to the ink bag 76.

[0023] When measurement and positioning are required for construction, the device can be used and brought to the construction site. The support bin 1 is fixed on the wall or the ground, and then the winding wheel 2 is driven to rotate by turning the crank 3 to release the pull rope 5. After the release is completed, the winding wheel 2 is contacted by twisting the adjusting screw 4 to fix the winding wheel 2 and stop it from rotating. Then, the connecting frame 6 is pulled by the handle to move, and then the connecting frame 6 is fixed on the wall or the ground to straighten the pull rope 5. Then, the height of the lifting frame 73 is adjusted to make the sponge ring 75 contact the wall or the ground, and the ink in the ink bag 76 flows from the lifting frame 73 into the rotating bin 74 and then flows on the rotating bin 74. The lifting frames 73 are all hollow structures, which are convenient for the ink to flow out of the rotating bin 74. The support frame 71 moves left and right, causing the support wheel 72 to rotate, thereby driving the lifting frame 73 to move, causing the rotating bin 74 to rotate, and then driving the sponge ring 75 to rotate. During the movement of the lifting frame 73, the lifting frame 73 will move up and down to adapt to the undulations of the ground, thereby drawing lines on the wall or on the ground for measurement and positioning, and can accurately draw straight lines or mark points, reduce errors, ensure the accuracy and precision of construction, and prevent ink from sticking to the hands of operators. After the measurement is completed, pull the lifting frame 73 to reset, so that the sponge ring 75 is separated from the wall or the ground, the support bin 1 and the connecting frame 6 are removed, and then the support frame 71 is moved and reset, and then the adjusting screw 4 is twisted in the reverse direction to disengage the winding wheel 2, and the winding wheel 2 is driven to rotate by rotating the crank 3 in the reverse direction, and the pull rope 5 can be reeled in.

[0024] like Figure 1 and Figure 5 As shown, it also includes a tensioning mechanism 8, which includes a support arm 81, a rotating frame 82, a contact wheel 83 and a torsion spring 84. The support arm 81 is connected to the left side of the upper part of the connecting frame 6, and the support arm 81 is in contact with the pull rope 5. The support arm 81 is rotatably connected to the rotating frame 82, and the contact wheels 83 are rotatably connected to the upper and lower sides of the rotating frame 82. The contact wheels 83 are in contact with the pull rope 5, and two front and rear torsion springs 84 are connected between the rotating frame 82 and the support arm 81.

[0025] Before pulling the support frame 71 to move left and right to draw a line, you can twist the rotating frame 82 on the support arm 81 to the left by hand, so that the torsion spring 84 is deformed, and then let go, the torsion spring 84 rotates and resets, thereby driving the rotating frame 82 to reset, so that the contact wheel 83 rotates and moves, thereby straightening the pull rope 5 for measurement and positioning, ensuring the accuracy of measurement and positioning, and preventing the pull rope 5 from loosening and causing inaccurate measurement and positioning.
