Description

Technical Field

[0001] This utility model relates to the technical field of tools for elevation measurement, specifically an assemblable leveling rod device. Background Technology

[0002] In elevation surveying, the level instrument and leveling rod are commonly used measuring tools. The level instrument is used to take readings, while the leveling rod provides the elevation point readings for the level instrument. Therefore, the accuracy of the elevation point measurement results is closely related to whether the leveling rod provides a standard reading scale. In actual engineering surveying, the leveling rod often relies solely on the surveyor to control its level to ensure accurate elevation point measurement. However, due to the weight of the leveling rod itself, the noisy working environment, and the limited ability of the surveyor to maintain a perfectly level level for a sustained period, and because the surveyor needs to signal the level instrument to take a reading (either by looking up or speaking loudly), the surveyor's arm may move unconsciously for a moment. All of these factors can lead to the level instrument being read while the leveling rod is tilted.

[0003] This degree of tilt is often very small, and due to factors in the work environment, the person using the leveling instrument cannot discern it. Furthermore, the person controlling the leveling rod often cannot clearly state whether the rod remained level for the few seconds following the initial reading, thus compromising the accuracy of the reading. In elevation measurements, errors accumulate gradually, leading to multiple reworks due to discrepancies between the measured and known elevations. This can even result in data modification after multiple unsuccessful reworks to achieve the desired measurement result. Utility Model Content

[0004] The purpose of this utility model is to provide a leveling rod device, which aims to solve the problems existing in the above-mentioned technical problems, so as to ensure the leveling rod is horizontal and facilitate the leveling rod operator to indicate the leveling instrument reading after the leveling rod is horizontal.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A leveling rod device, comprising:

[0007] Leveling board;

[0008] The leveling plate is detachably mounted on the connecting member;

[0009] An adjustable leg is movably mounted on the connector, and the adjustable leg keeps the leveling plate in a vertical position.

[0010] A sign flag is movably mounted on the connector to alert workers.

[0011] This utility model also has the following technical features:

[0012] In one embodiment of this utility model, at least three sets of adjustable legs are provided on the connecting member, and the length of the adjustable legs is adjustable.

[0013] In one embodiment of this utility model, the connector is provided with a slot, the slot is vertical, and the leveling plate is locked in the slot.

[0014] In one embodiment of this utility model, the connector is provided with a fixing member, and the fixing member extends out of the two sides of the slot and abuts against or separates from the two sides of the leveling plate.

[0015] In one embodiment of this utility model, a flagpole is provided on the flag, and the flagpole and the connecting member are in a rotatable fit.

[0016] In one embodiment of this utility model, a connecting bearing is provided on the connector, and a plug is provided at the end of the flagpole, the plug being inserted into the inner ring of the connecting bearing.

[0017] In one embodiment of this utility model, the fixing member is a fastening bolt, and fastening nuts are provided on both sides of the groove wall of the slot, and the fixing member is screwed into the fastening nuts.

[0018] In one embodiment of this utility model, the connector is provided with a hinged connecting seat, the hinge axis of the hinged connecting seat is horizontal, and the adjusting leg is tubular in shape with one end inserted into the hinged connecting seat.

[0019] In one embodiment of the present invention, the hinge shaft end of the hinge connector is provided with a nut section, and a locking nut is provided on the nut section, the locking nut being used to lock the hinge shaft.

[0020] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0021] The adjustable legs are movably mounted on the connector, allowing for real-time and precise adjustment of the leveling rod's angle based on the flatness and inclination of the actual measured ground. Whether on uneven construction sites or sloping terrain, the flexible adjustment of the adjustable legs' extension and angle ensures the leveling rod remains vertical, eliminating measurement errors caused by leveling rod inclination at the source. This significantly improves the accuracy and reliability of elevation measurement data, providing solid data support for engineering construction, topographic mapping, and other work.

[0022] The movable marker flags, mounted on the connectors, can be flexibly adjusted in position and angle according to the work scenario and measurement needs. In complex measurement environments, especially when there is insufficient light, limited visibility, or the measurement personnel are far away, the marker flags can attract the attention of the operators in a conspicuous manner, clearly indicating the accurate position of the leveling rod, avoiding measurement deviations or misoperations caused by visibility problems, effectively improving the efficiency and safety of measurement operations, and also facilitating cooperation among team members to ensure the smooth progress of the measurement work.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] In actual engineering surveying, the leveling rod often relies solely on the surveyor to maintain its horizontal position to ensure accurate elevation measurements. However, due to the weight of the leveling rod itself, noisy working environments, and the limited ability of the surveyor to maintain a perfectly horizontal level for an extended period, coupled with the fact that the surveyor needs to signal the leveling instrument to take a reading (either by looking up or speaking loudly), the surveyor's arm may move unconsciously for a moment. All of these factors can lead to the leveling instrument being read while the leveling rod is tilted. This tilt is often very slight, and due to the working environment, the person using the leveling instrument may not be able to discern it. Furthermore, the person controlling the leveling rod often cannot clearly state whether the rod remained horizontal for the few seconds following the signal to begin reading, thus compromising the accuracy of the reading. In elevation measurement, errors accumulate gradually, leading to repeated rework due to discrepancies between the measured and known elevations. This can even result in data modification after multiple unsuccessful rework attempts to achieve the desired measurement results. To address this, a leveling rod device is proposed, comprising: a leveling rod plate 10; a connecting member 20, wherein the leveling rod plate 10 is detachably mounted on the connecting member 20; an adjusting leg 30, movably mounted on the connecting member 20, which keeps the leveling rod plate 10 vertical; and a marker flag 40, movably mounted on the connecting member 20, to alert the operator.

[0033] In one embodiment, at least three sets of the adjusting legs 30 are provided on the connector 20, and the length of the adjusting legs 30 is adjustable.

[0034] In one embodiment, two sets of adjusting legs 30 are provided on both sides of the connector 20, and one set of adjusting legs 30 is provided behind the connector 20, for a total of three sets. The three sets of adjusting legs 30 are movably connected, which can reliably support the leveling plate 10, prevent the entire device from tipping over, and facilitate handling and transportation.

[0035] In one embodiment, the adjusting leg 30 has three sections, with a maximum diameter of 10 mm, a minimum diameter of 9.2 mm, and a length of approximately 1350 mm, and is made of stainless steel.

[0036] In one embodiment, the adjusting leg 30 is a telescopic rod, which can be an existing mature telescopic rod device. By adjusting the length of the adjusting leg 30, it can adapt to different working terrains, so that the leveling rod plate 10 remains vertical, thereby improving the accuracy of elevation measurement data.

[0037] When the leveling rod plate 10 is actually connected to the connector 20, the connector 20 is provided with a slot 21, the slot 21 is vertical, and the leveling rod plate 10 is locked in the slot 21.

[0038] In one embodiment, in order to fix the leveling plate 10 and the connector 20, the connector 20 is provided with a fixing member 22, which extends out of the two side walls of the slot 21 and abuts against or separates from the two sides of the leveling plate 10.

[0039] Specifically, the fixing member 22 is a fastening bolt, and fastening nuts 211 are provided on both sides of the groove wall of the slot 21. The fixing member 22 is screwed into the fastening nuts 211. When the leveling plate 10 is inserted into the groove 21, the end of the fastening nut 211 extends out of both sides of the groove wall of the slot 21 by screwing the fastening nut 211, thereby clamping the leveling plate 10 on both sides.

[0040] In one embodiment, the flag flag 40 is provided with a flagpole 41, and the flagpole 41 and the connector 20 are in a rotatable engagement.

[0041] In one embodiment, the identification flag 40 can be a striking yellow or orange-red color, with a flag height of approximately 120 mm and a width of approximately 50 mm.

[0042] To achieve a straight swinging state between the flag 40 and the connector 20, a connecting bearing 24 is provided on the connector 20, and a plug 411 is provided at the end of the flagpole 41, with the plug 411 inserted into the inner ring of the connecting bearing 24.

[0043] In one embodiment, the insertion rod 411 and the inner ring of the connecting bearing 24 are interference fit. The insertion rod 411 can be pressed into the inner ring of the connecting bearing 24 to achieve a rotational connection, thereby making it convenient for the operator to swing the identification flag 40 so that the identification flag 40 is in a waving state.

[0044] In one embodiment, a PTFE (polytetrafluoroethylene) washer can be provided on the inner wall of the inner ring of the connecting bearing 24 to prevent the flagpole 41 from moving unexpectedly due to vibration or external force, thereby ensuring measurement accuracy and operational reliability. After the marker flag 40 is installed with the flagpole 41, the flagpole is temporarily kept vertical. After the entire device is connected to the leveling plate 10, the surveyor can use a plumb bob to precisely adjust the vertical state of the marker flag 40 to ensure that the initial state of the marker flagpole is vertical, so that it can be rotated to a horizontal state for illustration during subsequent measurements.

[0045] In one embodiment, to achieve a movable connection between the adjusting leg 30 and the connecting member 20, the connecting member 20 is provided with a hinged connecting seat 23, the hinge axis of the hinged connecting seat 23 is horizontal, and the adjusting leg 30 is generally tubular with one end inserted into the hinged connecting seat 23.

[0046] Specifically, after adjusting the position so that the leveling plate 10 remains vertical, the hinge shaft end of the hinge connecting seat 23 is provided with a nut section, and a locking nut 231 is provided on the nut section. The locking nut 231 is used to lock the hinge shaft. By screwing the locking nut 231, the locking nut 231 abuts against the connecting piece 20, thereby locking the hinge shaft of the connecting seat 23, fixing the adjusting leg 30 and preventing it from tipping over.

[0047] In one embodiment, a non-slip rubber pad can be fitted onto one end of the adjusting leg 30 to further prevent the adjusting leg 30 from shifting, thereby preventing the entire device from tipping over.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
