Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological exploration technology, specifically to a portable surveying and marking pole. Background Technology
[0002] Geological exploration is short for geological exploration work. Broadly speaking, it can generally be understood as synonymous with geological work. It involves investigating and studying the geological conditions of a specific area, including rocks, stratigraphy, minerals, groundwater, and landforms, based on the needs of economic development, national defense, and scientific and technological advancements. Different types of geological exploration work exist depending on their purpose. Before conducting a geological exploration, designers need to survey the site, thus requiring the installation of markers for auxiliary purposes. In the surveying process, markers are a common and important tool used for on-site measurement and positioning.
[0003] The primary function of a benchmark is to serve as a reference point, facilitating accurate measurements and mapmaking by surveyors. The functions of a benchmark are: 1. Providing a stable reference point. As a measurement reference, a benchmark must possess stability. By fixing the benchmark to the ground, it ensures that it is not disturbed by external factors during the measurement process, thus greatly improving the accuracy and reliability of the measurement. 2. Achieving precise measurements. Benchmarks are usually engraved with scales, allowing direct measurement of distances and heights. Surveyors can accurately measure objects or locations on the ground based on the scales on the benchmark, thereby creating accurate maps. To ensure accuracy, benchmarks generally need to be kept vertical. 3. Achieving relative positioning. Relative positioning is required during measurement and mapmaking. Benchmarks can serve as fixed reference points, allowing measurements to be taken at different points to establish a coordinate system and achieve relative positioning.
[0004] Utility model CN222013133U discloses a field of geological exploration technology, specifically relating to a convenient geological exploration marker. It includes a flat plate with a detachably fixed drill rod. A circular hole is opened on one side of the plate, and multiple push rods are evenly distributed and fixed within the hole. A universal ball is installed at the end of each push rod facing the axis of the circular hole. A sphere is placed inside the circular hole, with its lower outer edge in rolling contact with the universal ball. A vertical connecting rod is fixed to the lower end of the sphere, and a counterweight ball is fixed to the lower end of the connecting rod. The sphere, connecting rod, and counterweight ball are concentric. A marker is fixed to the upper end of the sphere, with its axis coinciding with the axis of the connecting rod. A positioning component is provided on the flat plate to stabilize the sphere. This utility model utilizes the drill rod to stabilize the flat plate, and under the gravity of the counterweight ball, the marker can remain parallel to the horizontal plane. It can automatically adjust the marker to maintain its parallelism with the horizontal plane.
[0005] Although this utility model can ensure that the marking is always vertical, in actual use it has been found that when setting up the marker, a fixed point is usually made on the ground, and the marker needs to be directly inserted into the fixed point. However, in actual use, the rod and the marker are not collinear, which causes the marker to not coincide with the fixed point. Utility Model Content
[0006] The purpose of this invention is to provide a portable surveying and marking pole, which can be adjusted in actual use to make the pole coincide with the fixed point, thereby improving the positioning accuracy of the pole.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A portable surveying and marking pole includes a mounting plate, a chisel rod mounted on the mounting plate, a movable plate, a ball, a marker, and a counterweight. The movable plate is slidably mounted on the mounting plate, and an adjustment unit is provided on the movable plate for adjusting the distance between the movable plate and the mounting plate.
[0009] A spherical groove is provided on the movable plate, the sphere is movably installed in the spherical groove, the marker is installed at the upper end of the sphere, the counterweight is set at the lower end of the sphere, and the extension line of the marker axis and the center of gravity of the counterweight passes through the center of the sphere.
[0010] Furthermore, the mounting plate is provided with guide rods, and the movable plate is provided with guide holes. The guide rods pass through the guide holes to achieve a sliding connection between the mounting plate and the movable plate.
[0011] The adjustment unit includes a spring and an adjustment handwheel. The spring is fitted onto a guide rod, and the end of the guide rod that extends through the guide hole and out of the movable plate is threaded. The adjustment handwheel engages with the thread on the guide rod.
[0012] Further optimization includes the addition of a thrust ball bearing, with one end of the thrust ball bearing fixedly mounted on the movable plate and the other end connected to the adjustment handwheel.
[0013] The movable plate is equipped with a fixing unit for fixing the ball.
[0014] Furthermore, a pressure plate is installed on the drill rod.
[0015] Preferably, the counterweight is equipped with a positioning unit.
[0016] Furthermore, the positioning unit includes a laser emitting device mounted on a counterweight.
[0017] Among them, the marker is a telescopic pole.
[0018] Furthermore, the benchmark is to be made of plastic or carbon fiber materials.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This invention utilizes a counterweight and a sphere to keep the marker vertically downward under the influence of the counterweight. Simultaneously, a movable plate, adjusted by a unit, allows for the control of its position relative to the mounting plate. After inserting the marker, rotating the mounting plate positions the counterweight along the line extending from the fixed point. Adjusting the position of the movable plate relative to the mounting plate allows the movable plate to move closer to or further away from the marker. The process stops when the marker is above the fixed point, at which point the marker and the fixed point are aligned. In practical use, this invention allows for adjustment of the marker's position as needed, ensuring the marker coincides with the fixed point and improving its accuracy. Attached Figure Description

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0034] See Figures 1-3 This embodiment discloses a marker post, specifically a portable survey marker post, including a mounting plate 101, a chisel 102 mounted on the mounting plate 101, a movable plate 103, a ball 104, a marker 105, and a counterweight 106. The movable plate 103 is slidably mounted on the mounting plate 101, and an adjustment unit 109 is provided on the movable plate 103. The adjustment unit 109 is used to adjust the distance between the movable plate 103 and the mounting plate 101.
[0035] A spherical groove 110 is provided on the movable plate 103. The sphere 104 is movably installed in the spherical groove 110. The marker 105 is installed on the upper end of the sphere. The counterweight 106 is set at the lower end of the sphere 104. The axis of the marker 105 and the extension line of the center of gravity of the counterweight 106 pass through the center of the sphere 104.
[0036] This invention utilizes a counterweight 106 and a ball 104 to ensure the ball 104, under the action of the counterweight 106, keeps the marker 105 vertically downward. Simultaneously, the movable plate 103, through an adjustment unit 109, allows for positional adjustment between the movable plate 103 and the mounting plate 101. After inserting the drill rod 102, rotating the mounting plate 101 positions the counterweight 106 on the extension line of the fixed point and the drill rod 102. Then, adjusting the position between the movable plate 103 and the mounting plate 101 allows the movable plate 103 to move closer to or further away from the drill rod 102. The process stops when the marker 105 is above the fixed point, at which point the marker 105 and the fixed point are aligned. In practical use, this invention allows for adjustment of the marker 105's position as needed, ensuring the marker 105 coincides with the fixed point and improving the accuracy of the marker 105.
[0037] It should be noted that the fixed point mentioned in this embodiment is a preset point.
[0038] The mounting plate 101 is provided with a guide rod 111, and the movable plate 103 is provided with a guide hole 112. The guide rod 111 passes through the guide hole 112 to achieve a sliding connection between the mounting plate 101 and the movable plate 103. The guide rod 111 and the guide hole 112 enable the movable plate 103 to move stably.
[0039] Furthermore, in actual use, the mounting plate 101 is provided with a groove 113, and the guide rod 111 is located in the groove 113, with one end of the guide rod located in the groove 113; thus, when adjusting the position of the mounting plate 101 and the moving plate 103, the spring 107 is compressed into the groove 113, which serves to make way, allowing the mounting plate 101 and the moving plate 103 to contact each other, and thus a larger adjustment range.
[0040] The adjustment unit 109 includes a spring 107 and an adjustment handwheel 108. The spring 107 is fitted onto the guide rod 111, and the guide rod 111, extending through the guide hole 112 and out of the movable plate 103, is threaded. The adjustment handwheel 108 engages with the thread on the guide rod 111. By rotating the adjustment handwheel 108, the position between the movable plate 103 and the mounting plate 101 can be adjusted.
[0041] The adjustment unit 109 also includes a thrust ball bearing 114, one end of which is fixedly mounted on the movable plate 103, and the other end is connected to the adjustment handwheel 108. The thrust ball bearing 114 makes it easier to rotate the adjustment handwheel and avoids excessive friction between the adjustment handwheel and the movable plate 103, which would affect the smoothness of adjustment.
[0042] The movable plate 103 is equipped with a fixing unit 119 for fixing the ball 104. The fixing unit 119 secures the ball 104, preventing wobbling of the swing arm after positioning. The fixing unit includes a cylinder 115, an annular plate 116, and a stud 117. The stud 117 is fixedly mounted on the movable plate 103, which has an annular groove. The cylinder 115 is slidably mounted within the annular groove and has an extension 121. The stud 117 passes through the extension 121 and connects to a locking nut 118. The annular plate 116 is located inside the cylinder 115, and its contact with the ball 104 locks and secures the ball.
[0043] Furthermore, a pressure plate 120 is provided on the drill rod 102. The pressure plate 120 serves two purposes: first, to limit the movement, and second, to make it easier to insert the drill rod 102 into the ground.
[0044] Furthermore, in some preferred embodiments, the counterweight 106 is provided with a positioning unit.
[0045] The positioning unit includes a laser emitting device mounted on a counterweight 106. The laser emitting device illuminates the ground with a beam of light, and the light spot formed on the ground coincides with the positioning point, so as to facilitate the confirmation of the position of the marker 105.
[0046] Furthermore, the marker 105 is a telescopic rod, which is easy to carry, and the length of the marker 105 can be selected according to the needs of the site, thus improving the adaptability of the device.
[0047] Furthermore, the benchmark 105 is made of plastic or carbon fiber materials to reduce its weight.
[0048] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
