Description

Technical Field

[0001] This utility model relates to the field of railway surveying technology, specifically to a railway engineering surveying point marking device. Background Technology

[0002] In railway engineering surveying, fixed-point markers are the core spatial reference for the entire project, from surveying and design to construction and later operation and maintenance. They directly determine the quality of the project and operational safety. Fixed-point markers can ensure the accuracy and uniformity of the spatial positioning of the project, serve as the core guiding basis during the construction phase, and are the foundation for track smoothness and train operation safety.

[0003] However, in railway engineering surveying, the stability and applicability of the fixed-point marking device directly affect the measurement accuracy. Existing fixed-point marking devices are difficult to adapt to different ground specifications, resulting in insufficient stability and thus failing to meet engineering requirements.

[0004] Therefore, there is an urgent need for a railway engineering surveying and marking device that can adapt to different ground sizes. Summary of the Invention

[0005] The purpose of this invention is to provide a railway engineering surveying and marking device to at least solve the problem that existing marking devices are difficult to adapt to different ground sizes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A railway engineering surveying and marking device, comprising a marking rod;

[0008] A level is provided at the top of the marking rod, a cover plate is provided at the bottom of the marking rod, a support base is provided at the bottom of the cover plate, an airbag is provided at the bottom of the support base, and a vacuum pump is provided on the outer wall of the support base. The vacuum pump is connected to the airbag through the support base.

[0009] The airbag is filled with several spherical blocks.

[0010] Furthermore, the marking rod has a tubular structure.

[0011] Furthermore, the cover plate includes a connecting plate and a protrusion, the protrusion being disposed at the bottom center of the connecting plate, and the top of the connecting plate being disposed at the bottom of the marking rod.

[0012] Furthermore, the protrusion is cylindrical, and the outer wall of the protrusion is provided with external threads.

[0013] Furthermore, the support base includes a support column and a support plate, with the support column integrally disposed on the upper end surface of the support plate.

[0014] Furthermore, both the support column and the support plate are cylindrical structures with through holes inside, and the inner diameters of the support column and the support plate are the same.

[0015] Furthermore, the inner wall of the support column is provided with an internal thread that matches the external thread on the protrusion.

[0016] Furthermore, the side wall of the support base is provided with mounting holes.

[0017] Furthermore, a storage battery is installed inside the support base, and the storage battery is electrically connected to the vacuum pump.

[0018] Furthermore, a sealing structure is provided between the cover plate and the support base.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model provides a railway engineering surveying and marking device, which includes a marking rod, a level, a cover plate, a support base, a vacuum pump, an air bladder, and a ball block. The marking rod is held in place so that the bottom of the air bladder contacts the ground. Due to gravity, the ball block fills the bottom of the air bladder. The device is leveled using the level, and the vacuum pump is activated to remove air. This causes the air bladder to deform according to the different elevations or depressions on the ground. The vacuum pump compresses the ball block, allowing the ball block, along with the deformed air bladder, to clamp or fill the elevations or depressions on the ground, thus achieving stable placement of the device. Furthermore, the air bladder and ball block can adapt to different ground dimensions, facilitating the fulfillment of engineering requirements. Attached Figure Description

[0030] Example:

[0031] like Figure 1 As shown, this embodiment provides a railway engineering surveying and marking device, including a marking rod 1. The marking rod 1 has a tubular structure, which helps to reduce the weight of the device and makes it easy to use.

[0032] Specifically, a level 2 is welded and fixed to the top of the marking rod 1, which facilitates the adjustment of the device's horizontal state. A cover plate 3 is welded and fixed to the bottom of the marking rod 1.

[0033] The cover plate 3 includes a connecting plate and a protrusion. The protrusion is integrally set at the bottom center of the connecting plate, and the top of the connecting plate is set at the bottom of the marking rod 1.

[0034] Both the connecting plate and the protrusion are cylindrical, and the outer wall of the protrusion is provided with external threads.

[0035] Specifically, a support base 4 is provided at the bottom of the cover plate 3. The support base 4 includes a support column and a support plate. The support column is integrally set on the upper end face of the support plate. Both the support column and the support plate are cylindrical structures with through holes inside. The inner diameters of the support column and the support plate are the same, and the inner wall of the support column is provided with an internal thread that matches the external thread on the protrusion.

[0036] The diameter of the protrusion is smaller than the inner diameter of the support base 4, the height of the protrusion is smaller than the height of the support column, the diameter of the connecting plate is the same as the outer diameter of the support column, and the external thread of the protrusion matches the internal thread of the support column, so that the cover plate 3 is threaded onto the top of the support base 4 through the protrusion.

[0037] In this embodiment, a sealing structure is provided between the cover plate 3 and the support base 4. The sealing structure is a sealing rubber ring, which can enhance the sealing effect between the cover plate 3 and the support base 4.

[0038] An airbag 6 is provided at the bottom of the support base 4. The opening at the top of the airbag 6 is fixedly sleeved on the support plate of the support base 4. A vacuum pump 5 is provided on the outer wall of the support column. The vacuum pump 5 is connected to the airbag 6 through the support base 4.

[0039] The support base 4 has mounting holes on its side wall for mounting the vacuum pump 5.

[0040] Specifically, a storage battery is welded and fixed to the inner wall of the support base 4, and the storage battery is electrically connected to the vacuum pump 5. The storage battery supplies power to the vacuum pump 5 to ensure that the device can work independently. When the vacuum pump 5 is started, the air inside the airbag 6 is sucked out.

[0041] In this embodiment, as Figure 2 and Figure 3 As shown, the airbag 6 is filled with several small spheres 7. The spheres 7 do not need to completely fill the airbag 6 to avoid the airbag 6 being unable to contract effectively. When the bottom of the airbag 6 contacts the ground, due to gravity, the spheres 7 inside the airbag 6 will move towards the bottom of the airbag 6 to fill the airbag 6. Under the action of the vacuum pump 5, when the bottom of the airbag 6 contacts the ground, it will deform according to the different heights of the protrusions or depressions on the ground. The vacuum pump 5 causes the airbag 6 to compress the spheres 7, so that the spheres 7, together with the deformed airbag 6, clamp or fill the protrusions or depressions on the ground, thus making the device stably placed on the ground and suitable for placement on different sizes of ground.

[0042] The usage process of this embodiment is as follows:

[0043] Hold the marking rod 1, take the device, and place it at the location to be marked. The bottom of the airbag 6 contacts the ground. Due to gravity, the ball 7 inside the airbag 6 will move towards the bottom of the airbag 6 to fill it. Once the bottom of the airbag 6 is completely in contact with the ground, adjust the position of the device using the level 2 to make it level. Then start the vacuum pump 5. As the vacuum pump 5 sucks the air from inside the airbag 6, the bottom of the airbag 6 deforms according to the different heights of the bumps or depressions on the ground. Because the airbag 6 compresses the ball 7, the ball 7, along with the deformed airbag 6, clamps or fills the bumps or depressions on the ground, thus making the device stable on the ground.

[0044] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
