Description

Technical Field

[0001] The utility model relates to the technical field of subway tunnel construction, and mainly provides measurement, marking and positioning of pipeline supports in subway tunnels; more specifically, it relates to a measuring and marking device. Background Art

[0002] At present, during the construction of subway tunnel interval supports, there are slopes and curves in the tunnel. Most of the time, an infrared level is used in conjunction with a tape measure and an angle ruler to measure and mark the installation position of the interval supports; or a level is used in conjunction with a tower ruler to measure and mark the installation position of the interval supports.

[0003] These measurement methods are very cumbersome, requiring multiple point measurements, with large measurement errors, requiring a large number of personnel, and consuming a lot of construction time. Some brackets with high installation heights require the use of vertical ladders for measurement, which poses a high safety risk and seriously affects the construction progress and quality. In subway tunnels, rails need to be adjusted and sloped, and pipeline brackets are installed at different heights. Their installation angles and curvatures also need to be measured. Otherwise, there is a risk of intrusion after installation, affecting the overall construction quality. For the above problems, we propose a device that can quickly measure and mark.

[0036] See also Figure 1-4 , the utility model provides a technical solution:

[0037] A measuring and marking device, comprising:

[0038] Base 1, used as the overall support of the device;

[0039] A first support rod 2 is vertically rotatably connected to the middle of the base 1 through a rotating connection assembly 10, and the angle of the first support rod 2 relative to the base 1 can be adjusted;

[0040] The second support rod 3 is vertically connected to the top of the first support rod 2;

[0041] A first level 6, connected to the first support rod 2, for measuring whether the first support rod 2 is vertical;

[0042] A fixing assembly, used to keep the first support rod 2 at an adjusted angle;

[0043] An angle ruler 7, connected to the second support rod 3 near the first support rod 2;

[0044] A marking pen 5, which is telescopically connected to the end of the second support rod 3 and is used to draw lines on the structural surface;

[0045] The first support rod 2 and the second support rod 3 are both telescopic rods that can generate linear reciprocating motion.

[0046] Specifically, the first support rod 2 is a telescopic rod, so that the height of the second support rod 3 relative to the base 1 can be adjusted, and the second support rod 3 is a telescopic rod, so that the length of the second support rod 3 can be adjusted. The first support rod 2 and the second support rod 3 can be rod-shaped or plate-shaped, and the figure shows a plate-shaped.

[0047] Furthermore, the first support rod 2 and the second support rod 3 may be electric push rods, hydraulic push rods, jacks or the like.

[0048] When in use, move the device to the place where measurement and marking are required, observe the first level ruler 6, if the first support rod 2 is not vertical, adjust it to vertical, and fix it by the fixing assembly; measure the angle of the structural surface by the angle ruler 7; when marking is required, push the device and move it to the position where marking is required, make the marking pen 5 abut against the structural surface, push the device to move, and then marking can be done.

[0049] In this embodiment, the device also includes a second level ruler 8, which is connected to the second support rod 3 and is used to measure whether the second support rod 3 is horizontal; observe the second level ruler 8, if the second support rod 3 is not horizontal, rotate the first support rod 2 until the second support rod 3 is horizontal.

[0050] There are slope and curve sections in the tunnel, and the rigid connection is easy to damage the marker 5. In order to avoid damage to the marker 5, the device also includes a protection component, which includes a rotating disk 4, which can be rotatably connected to the bottom surface of the end of the second support rod 3 and the marker 5. The end surface of the second support rod 3 is dug with an inward groove 14, and a spring 13 is fixedly connected in the groove 14. The other end of the spring 13 is connected to the marker 5. An axial hole is opened in the middle of the rotating disk 4, and the bottom surface of the end of the second support rod 3 is fixedly connected to the connecting shaft. The connecting shaft can be inserted into the axial hole. The end of the connecting shaft protrudes a circle of edges for limiting and preventing the rotating disk from being separated from the connecting shaft. The length of the connecting shaft is slightly greater than the thickness of the rotating disk 4. The rotating disk 4 needs to ensure that the body of the marker 5 is located on the diameter of the rotating disk 4. When the spring 13 is in the natural state, the tip of the marker 5 extends out of the rotating disk 4. After the spring 13 is compressed, the tip of the marker 5 can be flush with the edge of the rotating disk 4.

[0051] Since the measuring and marking device is generally heavy and bulky, and it takes time and effort to carry it, in order to solve this problem, wheels 11 are connected to the four corners of the base 1.

[0052] In order to prevent the device from moving after the placement is completed, the wheel 11 is a wheel 11 with a brake.

[0053] In this embodiment, the fixing assembly includes a support seat 12 and a support telescopic rod 9. The support seat 12 is connected to both sides of the first support rod 2 on the base 1. The upper end of the support seat 12 is rotatably connected to the support telescopic rod 9 through a rotating connection piece. The end of the support telescopic rod 9 away from the support seat 12 is connected to the lower side of the first support rod 2. The two sides should be the two sides where the support telescopic rod 9 is tilted at an angle so that the first support rod 2 can be fixed. The rotating connection piece is not limited to hinges, hinges, etc. It is also possible to connect protruding plates on both sides of the lower part of the first support rod 2, and the end of the support telescopic rod 9 away from the support seat 12 is free. After the angle of the first support rod 2 is adjusted appropriately, the lengths of the two support telescopic rods 9 are adjusted so that they are against the two protruding plates.

[0054] In this embodiment, the rotating connection assembly 10 includes two fixed plates connected to the other two sides of the first support rod 2 on the base 1, that is, the midpoint line of the two fixed plates is perpendicular to the line connecting the two support seats 12, and the two fixed plates can be welded and integrally formed in the middle of the base 1, and the distance between the two fixed plates is adapted to the width of the bottom of the first support rod 2, so that the bottom of the first support rod 2 can be stuck between the two. Connecting shafts are connected to the two sides of the bottom of the first support rod 2, and connecting shaft holes are opened at positions adapted to the connecting shafts on the two fixed plates. The connecting shafts can be rotatably inserted into the connecting shaft holes, thereby realizing the change of the angle of the first support rod 2 relative to the base 1. During tunnel construction, there is generally an uneven ground inside, and the first support rod 2 needs to always remain vertical. The first support rod 2 can be rotated to a vertical position by rotating the connecting assembly 10.

[0055] In this embodiment, a counterweight is connected to the base 1 to make the device more stable when walking. The counterweight can be a lead block, a cement block, a cast steel or other object with a high density.

[0056] In this embodiment, the wheels 11 are nylon track wheels to cooperate with the tracks in the subway tunnel section to facilitate driving.

[0057] Specifically, in this embodiment, the supporting telescopic rod 9 is a hydraulic telescopic rod.
