Description

Technical Field

[0001] This utility model relates to the field of tunnel construction surveying and positioning technology, specifically a rapid positioning device for tunnel construction surveying. Background Technology

[0002] Construction surveying refers to the surveying work carried out for control, setting out, and final acceptance during construction. Construction setting out involves marking the location, shape, size, and elevation of the designed building on the ground according to the design drawings, so that construction can be carried out based on these points and lines. Therefore, a locating device is required.

[0003] For example, an existing patent (publication number: CN222560982U) discloses a precise point-fixing device for construction surveying. This device solves the problems of accuracy and efficiency in point marking during construction surveying. Compared with the previous measurement and layout, the efficiency is increased by 1.5 times, and it avoids the need for personnel to frequently bend over to mark points and the input of extra personnel. The device is lightweight and quick.

[0004] However, the above-mentioned construction surveying precision positioning device still has some drawbacks in actual use: although the construction surveying precision positioning device can avoid the need for personnel to frequently bend over to mark and the input of extra personnel, it still requires personnel to step on and press the rod in actual use, which makes the workload still relatively large and time-consuming and laborious.

[0005] To address these issues, we designed a rapid positioning device for tunnel construction surveying. Utility Model Content

[0006] The purpose of this invention is to provide a rapid positioning device for tunnel construction surveying to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a rapid positioning device for tunnel construction surveying, including a storage cylinder filled with paint, a piston plate slidably disposed inside the storage cylinder, an electric push rod disposed horizontally on one side of the storage cylinder, the driving end of the electric push rod slidably extending into the storage cylinder and fixedly connected to one side of the piston plate, and a discharge port communicating with the interior of the storage cylinder fixedly inserted at the end of the storage cylinder away from the electric push rod, and a valve disposed on the inner ring of the discharge port.

[0008] Furthermore, an airbag ring is provided on the inner ring of the discharge port, and an air collection box is fixedly installed on the top of the storage cylinder. A one-way air inlet valve and a one-way air outlet valve connected to the interior are respectively provided on the top and one side of the air collection box. An L-shaped tube connected to the interior is fixedly inserted into one side of the air collection box. Part of the one-way air outlet valve is located inside the L-shaped tube. The other end of the L-shaped tube is fixedly inserted into the discharge port and extends into the airbag ring. An inflation component for inflating the airbag ring is provided inside the air collection box.

[0009] Furthermore, the inflation assembly includes a piston component, which is slidably disposed within the air collection box. A pull rod is provided on one side of the piston component, and the other end of the pull rod slidably penetrates through the air collection box and is provided with a pull block. The diameter of the pull block is larger than the diameter of the pull rod.

[0010] Furthermore, a spring is provided between the piston and the inner wall of the gas collecting box, and the spring is movably sleeved on the pull rod.

[0011] Furthermore, a material injection pipe connected to the interior is fixedly inserted into the top of the storage cylinder, and a cap is movably sleeved on the other end of the material injection pipe.

[0012] Furthermore, a handle is provided at one end of the bottom of the storage cylinder, and the outer surface of the handle is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by oriented the storage cylinder and the outlet toward the measurement point, and then opening the electric push rod and the valve, the drive end of the electric push rod can be extended to drive the piston plate to move inside the storage cylinder, and the paint can be sprayed onto the point through the valve and the outlet, thus achieving the effect of electric positioning of the measurement point. The whole process requires less manual intervention, saving time and effort.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by pushing and pulling the block, the block can drive the pull rod and piston to move horizontally back and forth in the air collection box. During this process, outside air will be drawn into the air collection box through the one-way air intake valve, and then injected into the airbag ring through the one-way exhaust valve and L-shaped pipe, which can cause the airbag ring to expand, thereby changing the diameter of the inner ring of the airbag ring, so as to adjust the size of the sprayed paint according to the requirements of the site.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a rapid positioning device for tunnel construction measurement, including a storage cylinder 1 filled with paint, a piston plate 2 slidably disposed inside the storage cylinder 1, an electric push rod 3 disposed horizontally on one side of the storage cylinder 1, the driving end of the electric push rod 3 slidably extends into the storage cylinder 1 and is fixedly connected to one side of the piston plate 2, and a discharge port 4 communicating with the interior is fixedly inserted into one end of the storage cylinder 1 away from the electric push rod 3, and a valve 17 is disposed on the inner ring of the discharge port 4.

[0022] In practice, personnel first measure the points at the tunnel construction site. Then, personnel hold the storage cylinder 1 and point the discharge port 4 toward the measurement points. Then, they open the electric push rod 3 and the valve 17, which causes the drive end of the electric push rod 3 to extend and drive the piston plate 2 to move inside the storage cylinder 1. The paint is then sprayed onto the measurement points through the valve 17 and the discharge port 4, thus achieving the effect of electric positioning of the measurement points. The whole process requires less manual intervention and saves time and effort.

[0023] See Figure 1-4 An airbag ring 5 is provided in the inner ring of the discharge port 4. An air collection box 6 is fixedly installed on the top of the storage cylinder 1. A one-way air inlet valve 7 and a one-way air outlet valve 8 connected to the interior are respectively provided on the top and one side of the air collection box 6. An L-shaped tube 9 connected to the interior is fixedly inserted into one side of the air collection box 6. Part of the one-way air outlet valve 8 is located inside the L-shaped tube 9. The other end of the L-shaped tube 9 is fixedly inserted into the discharge port 4 and extends into the airbag ring 5. An inflation component for inflating the airbag ring 5 is provided inside the air collection box 6.

[0024] The inflation assembly includes a piston 10, which is slidably disposed in the air collection box 6. A pull rod 11 is provided on one side of the piston 10, and the other end of the pull rod 11 slides through the air collection box 6 and is provided with a pull block 12. The diameter of the pull block 12 is larger than the diameter of the pull rod 11.

[0025] In specific implementation, based on the above implementation, by pushing and pulling the pull block 12, the pull block 12 can drive the pull rod 11 and the piston 10 to move horizontally back and forth in the air collection box 6. During this process, outside air will be drawn into the air collection box 6 through the one-way air intake valve 7, and then injected into the airbag ring 5 through the one-way exhaust valve 8 and the L-shaped pipe 9, which can cause the airbag ring 5 to expand, thereby changing the diameter of the inner ring of the airbag ring 5, so as to adjust the size of the sprayed paint according to the site requirements.

[0026] In addition, it should be noted that we also need to install an exhaust pipe on the discharge port 4, which extends into the airbag ring 5, and install an air vent valve on the exhaust pipe. Opening the air vent valve allows the gas inside the airbag ring 5 to be discharged, making it convenient to inflate the airbag ring 5 next time.

[0027] See Figure 1-4 A spring 13 is provided between the piston 10 and the inner wall of the air collection box 6, and the spring 13 is movably sleeved on the pull rod 11. When the pull block 12 drives the piston 10 to one end inside the air collection box 6 and is released, the spring 13 will push the piston 10 back to its original position due to its own elasticity, which makes it easier for people to push and pull the piston 10.

[0028] See Figure 1-4 The top of the storage cylinder 1 is also fixedly connected to an injection pipe 14 that communicates with the interior, and the other end of the injection pipe 14 is movably fitted with a cap 15. Removing the cap 15 from the injection pipe 14 makes it easy to replenish paint in the storage cylinder 1.

[0029] See Figure 1-4 A handle 16 is provided at one end of the bottom of the storage cylinder 1, and the outer surface of the handle 16 is provided with anti-slip texture. This makes it convenient for personnel to hold the fixed device, achieving a portable effect, and the anti-slip texture can increase the friction between the personnel's hand and the handle 16, thereby reducing the problem of slippage.

[0030] Working principle: Before use, all electrical appliances involved in the fixed-point device need to be connected to an external power source, or a battery pack needs to be installed in an area outside the storage cylinder 1 that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the devices. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0031] In use, personnel first measure the points at the tunnel construction site. Then, personnel hold handle 16 and align the storage cylinder 1 and the outlet 4 with the measurement points. Then, they open the electric push rod 3 and valve 17, which extends the drive end of the electric push rod 3 and drives the piston plate 2 to move inside the storage cylinder 1. The paint is then sprayed onto the measurement points through valve 17 and outlet 4, thus achieving the effect of electric positioning of the measurement points. The whole process requires less manual intervention, saving time and effort.

[0032] Furthermore, during the above operation, by pushing and pulling the pull block 12, the pull block 12 can drive the pull rod 11 and the piston 10 to move horizontally back and forth in the air collection box 6. During this process, outside air will be drawn into the air collection box 6 through the one-way air intake valve 7, and then injected into the airbag ring 5 through the one-way exhaust valve 8 and the L-shaped pipe 9, which can cause the airbag ring 5 to expand, thereby changing the diameter of the inner ring of the airbag ring 5, so as to adjust the size of the sprayed paint according to the site requirements.
