Description

Technical Field

[0001] This utility model belongs to the field of surveying and mapping engineering technology, specifically, it relates to a surveying and mapping auxiliary surveying device. Background Technology

[0002] In surveying engineering, the leveling rod is the core tool used in conjunction with the level instrument to measure elevation. Its structure usually consists of multiple sections of extendable rod body and a base. When using it, the leveling rod needs to be placed vertically at the measurement point, and the elevation is calculated by reading the scale on the rod body through the level instrument.

[0003] Chinese patent CN222635483U discloses a surveying auxiliary mapping device. Lubricating oil is added to an oil filling tank through a filler port. After the oil is added, a telescopic rod can be pushed forward, which drives an oil filling piston forward. This piston forces the lubricating oil from the oil filling tank into lubrication grooves within a rubber sleeve. During the telescopic movement of the leveling rod, the lubricating oil in the grooves is coated onto the leveling rod, forming an oil film. This reduces friction between the leveling rod sections, prevents wear on the scale, and extends the lifespan of the leveling rod. However, the thrust and speed of the telescopic rod rely entirely on manual feel, making it impossible to quantify the amount of oil added. Excessive thrust leads to excessive lubricating oil overflow, wasting consumables and potentially contaminating the scale on the leveling rod. Insufficient thrust results in insufficient lubricating oil, failing to form a complete oil film and still exacerbating friction and wear between the leveling rod sections.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a surveying and mapping auxiliary surveying device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A surveying and mapping auxiliary surveying device includes: a leveling rod body, which is composed of an outer leveling rod and an inner leveling rod, and the inner leveling rod and the outer leveling rod are sleeved together, and the inner leveling rod and the outer leveling rod are capable of relative extension and retraction; it also includes a lubrication component, which is disposed between the outer leveling rod and the inner leveling rod, and the lubrication component is used to deliver lubricating oil to the contact surface of the inner leveling rod and the outer leveling rod and form an oil film when the inner leveling rod and the outer leveling rod are in relative extension and retraction.

[0008] Optionally, the lubrication assembly includes a connecting seat, an oil storage box, and a roller. The connecting seat is connected to the surface of the outer rail gauge, the oil storage box is connected to the top of the outer rail gauge, and the roller is rotatably connected to the bottom of the oil storage box. The bottom of the roller surface passes through the oil storage box, the connecting seat, and the outer rail gauge in sequence, and abuts against the surface of the inner rail gauge.

[0009] Optionally, the oil storage box is composed of an oil storage chamber and an oil outlet chamber, and a first channel is provided between the oil storage chamber and the oil outlet chamber, and the roller is connected to the bottom of the oil outlet chamber.

[0010] Optionally, the oil storage box is further provided with a groove between the oil storage chamber and the oil outlet chamber, and a lifting plate is connected to the groove. The surface of the lifting plate is provided with a second channel corresponding to the first channel.

[0011] Optionally, a bolt is connected to the center of the lifting plate, the bottom end of the bolt passes through the lifting plate and connects to the groove, and the bolt is threadedly connected to the lifting plate.

[0012] Optionally, the oil storage box has an oil inlet at the top of the oil storage chamber, and a filter tube is threadedly connected to the oil inlet. The lower surface of the filter tube has multiple filter holes, and the top extends to the outside of the oil storage box. A sealing cap is threadedly connected to the top of the filter tube.

[0013] Optionally, the unconnected ends of the outer and inner leveling gauges are each connected to a support base. A guide groove is formed on the outer wall of the inner leveling gauge along the length direction. A guide block adapted to the guide groove is fixed on the inner wall of the outer leveling gauge. The guide block is slidably embedded in the guide groove.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up a graded cavity structure of oil storage chamber and oil outlet chamber, and cooperating with the corresponding design of the first channel and the second channel, the path control of lubricating oil delivery can be realized. The oil storage chamber serves as the main oil storage space, and the oil outlet chamber serves as the transition chamber. The two are connected through the first channel. The second channel on the lifting plate forms an adjustable flow cross section with the first channel, providing basic structural support for oil injection control. At the same time, rotating the bolt and using the thread transmission to drive the lifting plate to move up and down along the groove changes the overlapping area of ​​the second channel and the first channel (the larger the overlapping area, the larger the flow cross section), thereby quantitatively controlling the amount of lubricating oil flowing from the oil storage chamber into the oil outlet chamber and avoiding the uncertainty of relying on manual feel.

[0016] 2. By setting up a roller structure that abuts against the surface of the inner rail, the output of lubricating oil is linked and matched with the extension and retraction of the rail. The roller rotates synchronously with the extension and retraction of the inner rail, and its rotation speed matches the movement amplitude of the rail. This allows the amount of lubricating oil to be applied to be dynamically adjusted according to the actual movement requirements, further ensuring the precise matching of oil injection and lubrication needs, and avoiding over- or under-lubrication.

[0017] 3. By setting a stable oil film formation mechanism, the scale on the surface of the leveling rod is effectively protected, reducing scale damage caused by friction and wear, and extending the service life of the leveling rod.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figure 1-6 As shown, this embodiment provides a surveying engineering auxiliary surveying device, including: a leveling rod body, which is composed of an outer leveling rod 1 and an inner leveling rod 2, and the inner leveling rod 2 and the outer leveling rod 1 are sleeved together, and the inner leveling rod 2 and the outer leveling rod 1 can move relative to each other; it also includes an oiling component, which is disposed between the outer leveling rod 1 and the inner leveling rod 2, and the oiling component is used to deliver lubricating oil to the contact surface of the inner leveling rod 2 and the outer leveling rod 1 and form an oil film when the inner leveling rod 2 and the outer leveling rod 1 move relative to each other.

[0032] The main body of the leveling rod adopts a socket design of outer leveling rod 1 and inner leveling rod 2. The measurement length is adjusted by the relative extension and retraction of the inner and outer leveling rods, which takes into account both measurement flexibility and storage portability. The lubrication component is installed at the socket gap of the inner and outer leveling rods 1. Its core function is to use the relative movement of the inner and outer leveling rods as a "power source" to automatically complete the delivery of lubricating oil and the formation of oil film without additional manual operation. When the inner leveling rod 2 is pulled in the outer leveling rod 1, the force generated by the movement will bring the lubricating oil stored in the lubrication component into the contact gap between the two leveling rods. As the movement continues, the lubricating oil forms a stable pressure oil film in the gap, completely separating the metal surfaces that were originally in direct contact.

[0033] Example 2

[0034] Please see Figure 1-6 As shown, in this embodiment, the lubrication assembly includes a connecting seat 4, an oil storage box 5, and a roller 9. The connecting seat 4 is connected to the surface of the outer tower gauge 1. The oil storage box 5 is connected to the top of the outer tower gauge 1. The roller 9 is rotatably connected to the bottom of the oil storage box 5. The bottom of the surface of the roller 9 passes through the oil storage box 5, the connecting seat 4, and the outer tower gauge 1 in sequence, and abuts against the surface of the inner tower gauge 2. The inside of the oil storage box 5 consists of an oil storage chamber 13 and an oil outlet chamber 14. A first channel 15 is provided between the oil storage chamber 13 and the oil outlet chamber 14. The roller 9 is connected to the bottom of the oil outlet chamber 14. The oil storage box 5 also has a groove 17 between the oil storage chamber 13 and the oil outlet chamber 14. A lifting plate 10 is connected to the groove 17. A second channel 16 corresponding to the first channel 15 is provided on the surface of the lifting plate 10. A bolt 11 is connected to the center of the lifting plate 10. The bottom of the bolt 11 passes through the lifting plate 10 and is connected to the groove 17. The bolt 11 is threadedly connected to the lifting plate 10.

[0035] The connecting seat 4 is fixed to the surface of the outer tower gauge 1, serving as the mounting base for the oil reservoir 5 and ensuring the relative position stability between the oil reservoir 5 and the outer tower gauge 1. The oil reservoir 5 is divided into two chambers (oil reservoir 13 and oil outlet 14). The oil reservoir 13 is used for long-term storage of lubricating oil, and the oil outlet 14 serves as a transition chamber, connected to the oil reservoir 13 through the first channel 15, guiding the lubricating oil to the roller 9. The roller 9 is rotatably connected to the bottom of the oil outlet 14, and its lower end passes through the outer tower gauge 1 and abuts against the surface of the inner tower gauge 2. When the inner tower gauge 2 extends or retracts relative to the outer tower gauge 1, the friction of the inner tower gauge 2 surface drives the roller 9 to rotate, and the roller 9 delivers the lubricating oil from the oil outlet 14. The lubricant is evenly applied to the surface of the inner tower gauge 2. Simultaneously, as the inner tower gauge 2 moves, the lubricant is carried into the contact gap between the inner and outer tower gauges 1 to form an oil film. A lifting plate 10 is provided in the groove 17 between the oil storage chamber 13 and the oil outlet chamber 14. The second channel 16 on the lifting plate 10 corresponds to the first channel 15. By rotating the bolt 11 (threadedly connected to the lifting plate 10), the lifting plate 10 can be driven to move up and down, adjusting the overlapping area (i.e., the flow cross-section size) of the second channel 16 and the first channel 15, thereby controlling the amount of lubricant flowing from the oil storage chamber 13 into the oil outlet chamber 14 (the larger the overlapping area, the greater the flow rate), and avoiding excessive or insufficient lubricant overflow.

[0036] Example 3

[0037] Please see Figure 1-6 As shown, in this embodiment, the oil storage box 5 has an oil inlet at the top of the oil storage chamber 13. A filter tube 12 is threadedly connected to the oil inlet. The lower surface of the filter tube 12 has multiple filter holes, and the top extends to the outside of the oil storage box 5. A sealing cap 6 is threadedly connected to the top of the filter tube 12.

[0038] The oil inlet at the top of the oil storage chamber 13 is used to replenish lubricating oil. The filter tube 12 filters the injected lubricating oil through the filter holes on its surface (removing impurities and particles) to avoid clogging the channel or scratching the surface of the tower gauge. The sealing cover 6 can prevent dust and rainwater from entering the oil storage chamber 13 and ensure the cleanliness of the lubricating oil.

[0039] The unconnected ends of the outer gauge 1 and the inner gauge 2 are both connected to a support base 3. A guide groove 8 is provided on the outer wall of the inner gauge 2 along the length direction. A guide block 7 that matches the guide groove 8 is fixed on the inner wall of the outer gauge 1. The guide block 7 is slidably embedded in the guide groove 8.

[0040] The guide groove 8 on the outer wall of the inner leveling rod 2 and the guide block 7 on the inner wall of the outer leveling rod 1 form a sliding fit. Their function is to restrict relative rotation when the inner and outer leveling rods 1 extend and retract, ensuring that they only move along the axial direction (length direction), avoiding uneven wear or jamming of the contact surface caused by torsion. The support seat 3 is used to provide stable support when the leveling rod is placed, avoiding deformation and wear caused by the end of the leveling rod directly contacting the ground or other objects, while ensuring that the rod body is vertical during measurement and improving the stability of the reading.

[0041] Working principle:

[0042] When the measurement length needs to be adjusted, the operator pulls or pushes the inner ruler 2 to slide it inside the outer ruler 1. By changing the overlap length of the inner and outer rulers 1, the measurement range can be flexibly adjusted (such as extending from the short ruler state to the long ruler state, or vice versa). The guide groove 8 on the outer wall of the inner ruler 2 and the guide block 7 on the inner wall of the outer ruler 1 form a sliding fit, which restricts the relative rotation of the two during the extension and retraction process, ensuring that the movement is only along the axial direction, avoiding jamming, uneven wear or ruler body skew caused by torsion, and ensuring the stability and smoothness of the extension and retraction action.

[0043] The lubrication assembly uses the relative motion of the inner and outer gauges 1 as power to automatically complete the delivery, regulation, and oil film formation of lubricating oil. The specific process is as follows:

[0044] The oil storage chamber 13 of the oil storage box 5 is replenished with lubricating oil through the top oil inlet. When injecting, the lubricating oil first passes through the filter tube 12, and impurities (such as particles and dust) are removed through the filter holes on the surface of the filter tube 12 to prevent contaminants from entering the lubrication system. After the oil is injected, the sealing cap 6 is tightened to prevent the lubricating oil in the oil storage chamber 13 from being contaminated by the outside or evaporating. The operator can drive the lifting plate 10 to move up and down by rotating the bolt 11 to adjust the overlapping area of ​​the second channel 16 and the first channel 15. The larger the overlapping area, the more lubricating oil flows from the oil storage chamber 13 to the oil chamber 14. The smaller the overlapping area, the less the flow rate. Thus, the oil supply can be precisely controlled according to the usage frequency, ambient temperature and other requirements to avoid waste or insufficient supply.

[0045] The roller 9 at the bottom of the oil outlet chamber 14 directly abuts against the surface of the inner rail 2. When the inner rail 2 extends or retracts relative to the outer rail 1, the friction on the surface of the inner rail 2 drives the roller 9 to rotate synchronously. The rotating roller 9 evenly absorbs and coats the lubricating oil in the oil outlet chamber 14 onto the surface of the inner rail 2. As the inner rail 2 continues to slide, the lubricating oil coated on the surface is carried into the sleeve gap between the inner and outer rails 1, forming a stable pressure oil film on the contact surface. This separates the metal surfaces that were originally in direct contact, realizing the transformation from "solid friction" to "fluid friction", reducing wear and resistance.
