Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping poles, in particular to a pole used for centering or positioning in surveying and mapping technology, and specifically to a tiltable protective engineering surveying and mapping pole. Background Art

[0002] Surveying and mapping instruments include, but are not limited to, total stations, levels, and surveying instruments, which are used in the surveying and mapping procedures before construction projects and require the use of benchmarks to measure the construction. For example, in the prior art, a positioning benchmark for geological surveying with a publication number of CN117470206B relates to the technical field related to benchmarks and includes a stabilizing mechanism arranged at the bottom of a first-level benchmark. The invention provides a stabilizing mechanism that collects snow and sand in loose terrain and squeezes the loose sand, snow, and other materials through the extrusion of a displacement plate and a shrink film, thereby ensuring the stability of the benchmark. Normal squeezing of surface snow and sand can only achieve shallow surface compaction. Inserting a compacted surface benchmark into it still poses a risk of toppling and may not necessarily maintain stability. However, squeezing the sand and snow that are artificially piled above the surface can increase the height of the compacted portion, thereby making the benchmark more stable after insertion and maintaining stable support for the benchmark in special terrains such as deserts and snowfields, greatly improving the efficiency and effectiveness of stabilizing the benchmark in loose and special terrains such as deserts and snowfields.

[0003] Another example is a surveying pole for municipal engineering topographic surveying with a prior art announcement number CN117570946B, which includes a No. 1 support pole, a No. 2 support pole, and a No. 3 support pole. The No. 1 support pole has a symmetrically defined outer wall with a No. 1 limit slot, a No. 3 fixing pole symmetrically mounted inside the No. 1 limit slot, a No. 1 spring mounted on the outer wall of the No. 3 fixing pole, a limit plate slidably mounted on the inner wall of the No. 1 limit slot, a fixing block symmetrically mounted on the outer wall of the limit plate, and a No. 1 slot defined on the outer wall of the fixing block. By moving the No. 2 and No. 3 support poles, the limit plate is partially removed from the No. 1 limit slot, the No. 2 and No. 3 support poles are rotated 180°, and the No. 2 and No. 3 support poles are loosened, allowing the No. 1 and No. 2 plug poles to be inserted into the No. 1 slot and No. 2 slot, respectively. The surveying pole is quickly formed, avoiding the time-consuming and labor-intensive process of assembling the surveying pole through threaded connections.

[0004] The above-mentioned existing technologies have made relatively mature technical improvements to the splicing of the benchmarks themselves or the stable placement of the benchmarks in special terrains, and have high practical effects. However, although some of the existing technologies have stabilizing mechanisms that make the benchmarks more stable, the way in which the stabilizing mechanisms directly enter the pile makes the overall placement resistance of the benchmarks larger, and the actual use efficiency is not high. Summary of the Invention

[0005] The purpose of the present invention is to provide a tiltable protective engineering surveying marker to solve the problem raised in the above background technology that although some existing technologies have stabilizing mechanisms to make the markers more stable, the way in which the stabilizing mechanisms directly enter the pile makes the overall placement resistance of the marker greater and the actual use efficiency is low.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tippable protective engineering surveying and mapping marker, comprising a locator for stabilizing the marker on the ground, a reminder, and an operator for operating the above-mentioned functional devices, and the above-mentioned functional devices are connected by splicing parts that can be connected end to end. The bottom end of the locator is provided with a cone, and the side of the locator is connected to an anti-roll plate with an initial vertical distribution through a connecting rod, wherein the anti-roll plate is connected to a driving mechanism in the locator through the connecting rod for changing the state of the anti-roll plate.

[0007] Preferably, the driving mechanism includes a valve plate and a pressure plate distributed in sequence up and down, wherein the valve plate is driven to move vertically by an operator, and drives the pressure plate to press down synchronously and change the state of the anti-roll plate through a transmission mechanism.

[0008] Preferably, the transmission mechanism includes a rack fixed to the lower end surface of the pressure plate and a gear meshing with the rack, the gear is fixed to the inner end of the connecting rod, and the horizontally distributed connecting rod is rotatably mounted on the side wall of the positioner.

[0009] Preferably, the transmission mechanism includes a ring body fixed under the pressure plate, which is rotatably connected to the end of the connecting rod, and the square section of the middle section of the connecting rod slides through the guide groove, which is distributed in an arc shape and is used to guide the connecting rod to deflect synchronously when moving downward.

[0010] Preferably, the ends of the splicing piece are in mutually fitting connection structures, and the interior of the splicing piece contains an air cavity running vertically through it.

[0011] Preferably, the reminder comprises a connecting section in the lower half and a rotating section in the upper half, wherein the outer surface of the rotating section is inlaid with a rotatable and expandable display bar, and the inner wall of the display bar is rotatably connected to the bottom end of the pull rod.

[0012] As a preference, the top end of the pull rod is vertically slidably mounted in the rotating section, and a light bar is embedded on the surface of the display bar.

[0013] Preferably, the bottom end of the rotating section is connected to the mounting ring, wherein the mounting ring is threadedly embedded in the top end of the twisted rod, and the bottom end of the twisted rod is connected to the force plate, the edge of the force plate is sealed and fits vertically on the inner wall of the connecting section, and the force plate is driven to move by the operator.

[0014] Preferably, the light bar is powered and illuminated by the rotation of the rotating section, wherein a magnetic block is slidably installed in the inner cavity of the display bar.

[0015] Preferably, a coil is distributed around the periphery of the cavity, wherein the coil is coupled to the light bar.

[0016] Preferably, the operator includes a movable plate whose vertical movement can be controlled by an external slip ring, and a first magnetic plate is installed on the upper and lower sides of the movable plate, and corresponding to the magnetic plate is a second magnetic plate located at both ends inside the operator and attracted or repelled by the first magnetic plate.

[0017] Preferably, the two second magnetic plates are respectively connected to a movable plate, and the movable plate is driven to move vertically through the movement of the movable plate and the magnetic effect, so as to change the air pressure in the space outside the movable plate at the corresponding position and drive the locator or reminder, wherein the change in air pressure is transmitted to the locator or reminder through the splicing parts.

[0018] The beneficial effects of this surveying and mapping benchmark are: it adopts a movable positioning mechanism to adjust different usage states according to different surveying and mapping scenarios, and has less resistance and is more stable, more convenient to operate, and at the same time has a better reminder display effect, which is more suitable for use in dim light or special scenarios. The details are shown below.

[0019] 1. The anti-roll plate is designed to be movable and can be folded and stored in normal situations to reduce the difficulty of movement. At the same time, the anti-roll plate can be used to rotate to keep it in a vertical position before entering the pile to reduce the placement resistance. After entering the pile, it can be rotated to a horizontal position to utilize the resistance generated by the pile to ensure the stability of the marker on the flat surface.

[0020] Furthermore, the structural design of the ring body and the guide groove enables the anti-roll plate to tilt synchronously during the arc movement after entering the pile, thereby further reducing the resistance of the anti-roll plate to rotation and adjustment inside the pile, and improving practicality and placement stability.

[0021] 2. The use of a reminder composed of a display bar and other structures in the rotating section can realize the rotation and expansion of the display bar through simple manual operation of the construction workers to achieve a better eye-catching effect. At the same time, the use of its internal magnetic blocks and coils can synchronize the rotation of the reminder to realize the lighting function of the light bar, thereby cooperating with the revolution of the light bar itself to produce a light effect similar to a light ring, thereby facilitating surveyors to better locate the benchmark in dark light or special environments.

[0022] 3. The use of the operator in conjunction with the hollow structure splicing parts makes it convenient for construction workers to manually control the functions of the devices at the bottom and top of the benchmark. At the same time, the operation method of changing the air pressure through magnetic conduction can realize the normal operation of the benchmark after splicing at any length, which is more suitable for surveying and mapping operations in special construction areas such as deep pits.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-11 , the present invention provides the following technical solutions:

[0037] Example 1: The solution disclosed in this example is mainly to solve the problems existing in the prior art, such as Figure 1-Figure 2 As shown, it includes a locator 1 for stabilizing the benchmark on the ground, a reminder 4 and an operator 3 for operating the above-mentioned functional devices, and the above-mentioned functional devices are connected by a splicing piece 2 that can be connected end to end. The bottom end of the locator 1 is provided with a cone 6, and the side of the locator 1 is connected to an anti-roll plate 5 with an initial state of vertical distribution through a connecting rod 7, wherein the anti-roll plate 5 is connected to the driving mechanism in the locator 1 through the connecting rod 7, which is used to change the state of the anti-roll plate 5. The driving mechanism is essentially controlled by the operator 3, and the benchmark as a whole is still placed on the predetermined plane to be constructed through the cone 6. When there is a certain thickness of snow, sand or other materials on the plane, the anti-roll plate 5 with an initial state of vertical distribution The tilt plate 5 will be embedded in it, and the resistance will be relatively small. Later, if the benchmark needs to be in a non-handheld and stable standing state, the control mechanism can be driven by the operator 3 to convert the anti-tilt plate 5 from vertical to inclined or horizontal state. At this time, the sand, snow, etc. above the anti-tilt plate 5 will exert a limiting force on the anti-tilt plate 5, so that the benchmark as a whole is in a more stable distribution state, thereby achieving a better anti-tilt effect. At the same time, the anti-tilt plate 5 can also be set to a solution that can rotate or disassemble with the connecting rod 7 in a vertical state. In this way, under normal use, the anti-tilt plate 5 can be stored or removed to improve the convenience in normal use environments that require frequent movement.

[0038] The solution disclosed in this embodiment further discloses how to change the state of the anti-roll plate 5 when needed, such as Figure 2-Figure 3As shown, the driving mechanism includes a valve plate 9 and a pressure plate 8 distributed in sequence up and down, wherein the valve plate 9 is driven to move vertically by the operator 3, and drives the pressure plate 8 to press down synchronously and change the state of the anti-roll plate 5 through the transmission mechanism. The transmission mechanism includes a rack 10 fixed to the lower end face of the pressure plate 8 and a gear 11 meshing with the rack 10, and the gear 11 is fixed to the inner end of the connecting rod 7. At the same time, the horizontally distributed connecting rod 7 is rotatably mounted on the side wall of the positioner 1. When the bottom end of the positioner 1 is immersed in the accumulation above the ground, the valve plate 9 can be controlled to move downward by the operator 3. The reason for using the valve The plate has this structural form because the various functional components are connected by hollow structure splicing pieces 2. Therefore, the operator 3 can be used to change the air pressure and drive the valve plate to move through the sealing conduction of several splicing pieces 2. Therefore, after the valve plate 9 moves, it will drive the pressure plate 8 and the rack 10 below it to move synchronously. Therefore, under the meshing transmission action of the rack 10 and the gear 11, the connecting rod 7 will drive the anti-roll plate 5 to rotate from a vertical state to a horizontal state. Therefore, part of the deposits above the plane will be moved to the top of the anti-roll plate 5 and provide a limiting force, thereby improving the stability and anti-dumping effect of the benchmark.

[0039] Embodiment 2: The solution disclosed in this embodiment is different from the above embodiment. Figure 4-Figure 5 As shown, the transmission mechanism includes a ring body 13 fixed under the pressure plate 8, and the ring body 13 is rotatably connected to the end of the connecting rod 7. At the same time, the square section of the middle section of the connecting rod 7 slides through the guide groove 12. The guide groove 12 is distributed in an arc shape and is used to guide the connecting rod 7 to deflect synchronously when moving downward. The difference from the first embodiment is that the rotation scheme in the first embodiment is that after the anti-roll plate 5 has been immersed in the pile, the anti-roll plate 5 is directly rotated along the axis of the connecting rod 7, so that the rotation resistance to be overcome is greater. In this embodiment, the ring body 13 and the connecting rod 7 are pressed down by the pressure plate 8, so that the connecting rod 7 will first drive the anti-roll plate 5 to continue to slide downward. The vertical anti-roll plate 5 has less resistance to overcome downward, and while sliding, due to the guidance of the guide groove 12 and the middle section of the connecting rod 7, the anti-roll plate 5 will gradually rotate while moving downward along the arc trajectory. Therefore, the resistance overcome in the process of rotating from horizontal to horizontal state is smaller, and the depth is also deeper, so the anti-dumping effect is better.

[0040] Example 3: In the case of rainy or evening light conditions or when the surveyor / total station is too far away, the pole is not easy to be located by the instrument. Therefore, in order to solve this problem, this embodiment discloses the following method: Figure 7-Figure 9In the scheme shown, the ends of the splicing piece 2 are connected to each other, and the interior thereof contains an air cavity 14 running vertically through it. The reminder 4 includes a connecting section of the lower half and a rotating section 15 of the upper half, wherein the outer surface of the rotating section 15 is inlaid with a rotatable display bar 19, the inner wall of the display bar 19 is rotatably connected to the bottom end of the pull rod 21, and the top end of the pull rod 21 is vertically slidably installed in the rotating section 15, and the surface of the display bar 19 is also inlaid with a light bar 20, the bottom end of the rotating section 15 is connected to the mounting ring 16, wherein the mounting ring 16 is threadedly nested in the top end of the twisted rod 17, and the bottom end of the twisted rod 17 is connected to the The force plate 18 is connected, and the edge of the force plate 18 is sealed and fits and slides vertically on the inner wall of the connecting section, wherein the force plate 18 is driven to move by the operator 3. The operation of the operator 3 will cause the force plate 18 to move in the vertical direction. Therefore, the synchronous movement of the twisted rod 17 and the threaded transmission of the mounting ring 16 will drive the mounting ring 16 and the rotating section 15 to rotate. At this time, under the action of centrifugal force, the display bar 19 will rotate and expand accordingly, thereby making the overall benchmark more eye-catching, and combined with the light ring effect formed by the light bar 20 on its surface during the rotation of the display bar 19, it can be more suitable for environments with poor lighting.

[0041] This embodiment further discloses a solution for making the light bar 20 emit light and the brightness thereof related to the overall rotation speed of the rotating section 15, specifically as follows: Figure 9 As shown, the light bar 20 is powered and illuminated by the rotation of the rotating section 15, wherein a magnetic block 22 is slidably installed in the internal cavity of the display bar 19, and a coil 23 is distributed around the periphery of the cavity, wherein the coil 23 is coupled to the light bar 20. During the rotation of the rotating section 15, its rotation speed will not remain unchanged because it is manually controlled, so the moving speed of the magnetic block 22 in the space surrounded by the coil 23 will also change periodically accordingly, so the induced electromotive force will also change intermittently, so that the light bar 20 can produce a bright and dark alternating phenomenon, which can further improve the reminder effect of the benchmark in a dark light environment.

[0042] The operator 3 includes a movable plate 24 that can be controlled by an external slip ring for vertical movement. A first magnetic plate 25 is installed on the upper and lower sides of the movable plate 24, and corresponding to the magnetic plate is a second magnetic plate 26 located at both ends of the inside of the operator 3 and attracted or repelled by the first magnetic plate 25. The two second magnetic plates 26 are respectively connected to a movable plate 27, and the movable plate 27 is driven to move vertically through the movement of the movable plate 24 and the magnetic effect, so as to change the air pressure in the space outside the corresponding movable plate 27 and drive the positioner 1 or reminder 4. The change in air pressure is transmitted to the positioner 1 or reminder 4 through the splicing part 2, and drives the valve plate 9 and the force plate 18 to move in a predetermined direction.
