Description

Technical Field

[0001] This utility model belongs to the field of measurement equipment technology, specifically relating to an elevation measurement device for geodetic surveying. Background Technology

[0002] Elevation measurement, as a crucial technique for determining the vertical distance between any two points on the Earth's surface, directly impacts the accuracy, safety, and cost-effectiveness of subsequent engineering design and construction. Traditional elevation measurement primarily relies on precision optical instruments such as total stations. Total stations utilize laser ranging and angle measurement principles to accurately determine three-dimensional coordinates, providing strong support for geodetic surveying.

[0003] However, in current total station usage, tripods are typically used for support. When performing elevation measurements, surveyors need to operate the total station while standing. Since the measurement process takes a certain amount of time, surveyors need to remain standing for extended periods, increasing labor intensity and easily causing fatigue. Therefore, the applicant proposes an elevation measurement device for geodetic surveying to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an elevation measuring device for geodetic surveying, aiming to improve the current situation where total stations are usually supported by tripods. When performing elevation measurements, surveyors need to operate the total station in a standing position. Since the measurement operation takes a certain amount of time, surveyors need to remain standing in one place for a long time, which increases the labor intensity and easily causes fatigue to the surveyors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A geodetic elevation measuring device, comprising:

[0007] An elevation measuring mechanism and a seat mechanism mounted on the bottom of the elevation measuring mechanism;

[0008] The elevation measuring mechanism includes a fixed plate, and a plurality of support rods arranged in a circular array are hinged to the periphery of the fixed plate. A telescopic rod is sleeved at the bottom of the support rods.

[0009] The seat mechanism includes a fixed column fixedly installed at the bottom of the fixed plate, a movable sleeve slidably installed on the fixed column, a folding arm hinged to one side of the movable sleeve, a seat plate fixedly installed to one side of the folding arm, a support cylinder hinged to the bottom of the seat plate, and a support frame sleeved at the bottom of the support cylinder.

[0010] Preferably, a mounting base is fixedly installed on the top of the mounting plate, and a total station is connected to the top of the mounting base.

[0011] Preferably, the support rod and the telescopic rod are fixed together by a first fixing knob, and an anti-slip cone is fixedly installed at the bottom of the telescopic rod.

[0012] Preferably, a limiting plate is fixedly installed at the bottom of the fixed column, and the periphery of the limiting plate is provided with multiple slots corresponding to the support rod.

[0013] Preferably, the movable sleeve is fixed to the fixed post by a second fixing knob, and a magnetic block corresponding to the fixed post is fixedly installed on the top of the folding arm.

[0014] Preferably, the front and rear ends of the support cylinder are hinged to a limit frame, and the front and rear ends of the folding arm are fixedly installed with limit posts that engage with the limit frame.

[0015] Preferably, the support cylinder is fixed to the support frame by a third fixing knob, and a sponge pad is attached to the top of the seat plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The present invention is provided with a seat mechanism on the elevation measuring mechanism. When using the elevation measuring mechanism for measurement, the seat mechanism can be unfolded so that the seat board can be flipped to a horizontal state. The seat board can be adjusted up and down to make it convenient for measuring personnel of different heights to use. The measuring personnel can sit on the seat board to perform the elevation measuring operation, which can effectively avoid the fatigue caused by standing for a long time and reduce the labor intensity of the measuring personnel. At the same time, after use, the seat mechanism can be folded and stored, so that the seat mechanism and the elevation measuring mechanism can be combined and stored together for easy carrying and transportation.

[0018] (2) The present invention provides a limiting plate at the bottom of the fixed column, which allows the support rod to be snapped into the slot after it is retracted, making it easy to lock and fix the support rod. This can prevent the support rod from shaking and coming apart during carrying, bringing more convenience to carrying and operation. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an elevation measuring device for geodetic surveying includes:

[0030] Elevation measuring mechanism 1 and seat mechanism 2 mounted on the bottom of elevation measuring mechanism 1;

[0031] The elevation measuring mechanism 1 includes a fixed plate 11, and a plurality of support rods 12 arranged in a ring array are hinged to the periphery of the fixed plate 11. A telescopic rod 13 is sleeved at the bottom of the support rods 12.

[0032] The seat mechanism 2 includes a fixed column 21 fixedly installed at the bottom of the fixed plate 11. A movable sleeve 22 is slidably installed on the fixed column 21. A folding arm 26 is hinged to one side of the movable sleeve 22. A seat plate 28 is fixedly installed on one side of the folding arm 26. A support cylinder 29 is hinged to the bottom of the seat plate 28. A support frame 210 is sleeved on the bottom of the support cylinder 29.

[0033] As can be seen from the above, when using this device, it is moved to a suitable position, and the support rod 12 is flipped outward and unfolded. The telescopic rod 13 can support the ground, which can facilitate the support of this device. The telescopic rod 13 can move in and out along the inside of the support rod 12, which can facilitate the adjustment of the height of the fixed plate 11 and the adjustment operation can be carried out according to the measurement requirements.

[0034] By flipping the folding arm 26 outward, the seat plate 28 can be made horizontal. The movable sleeve 22 can slide up and down along the fixed column 21, which can easily adjust the height of the seat plate 28, making it suitable for measurement personnel of different heights. By flipping the support cylinder 29 to a vertical state, the support frame 210 can easily support the ground. The support frame 210 can slide up and down along the support cylinder 29, which can easily adjust the height of the seat plate 28 from the ground, providing support for the seat plate 28. Measurement personnel can sit on the seat plate 28 to perform measurement operations on the elevation measurement mechanism 1, which can effectively avoid the fatigue caused by standing for a long time and reduce the labor intensity of measurement personnel.

[0035] After use, by flipping the folding arm 26 upward to a vertical position, the seat plate 28 can be flipped up and erected simultaneously. Using the effect of gravity, the support cylinder 29 can be kept vertical and can fit against one side of the folding arm 26. Sliding the support frame 210 upward can retract it into the support cylinder 29, which can easily fold and store the entire seat mechanism 2 at the bottom of the fixed plate 11. This allows the seat mechanism 2 and the elevation measuring mechanism 1 to be combined and stored together, making it convenient for carrying and transportation.

[0036] Depend on Figure 3 It can be seen that a fixed base 16 is fixedly installed on the top of the fixed plate 11, and a total station 17 is connected to the top of the fixed base 16.

[0037] As can be seen from the above, the total station 17 can be easily fixed on the fixed plate 11 by the fixed base 16, which can easily support the total station 17 and enable the measurement function of the total station 17 to perform elevation measurement operations.

[0038] For details, please refer to Figure 3 As shown, the support rod 12 and the telescopic rod 13 are fixed together by the first fixing knob 15, and the bottom of the telescopic rod 13 is fixedly installed with an anti-slip cone 14.

[0039] As can be seen from the above, the telescopic rod 13 can be easily fixed at a suitable length by the first fixing knob 15, and the operating height of the total station 17 can be easily adjusted according to the measurement requirements. The anti-slip cone 14 can increase the friction between the telescopic rod 13 and the ground, making it less likely for the telescopic rod 13 to slide or displace between itself and the ground.

[0040] For details, please refer to Figure 2 and Figure 4 As shown, a limiting plate 24 is fixedly installed at the bottom of the fixed column 21, and multiple slots 25 corresponding to the support rod 12 are opened on the periphery of the limiting plate 24.

[0041] As can be seen from the above, by folding the support rod 12, the support rod 12 can be inserted into the slot 25. The limiting plate 24 can support and limit the support rod 12, which can prevent the support rod 12 from shaking and falling apart during carrying, thus bringing more convenience to carrying and operation.

[0042] Example 2:

[0043] refer to Figure 4 and Figure 5 As shown, the movable sleeve 22 is fixed to the fixed post 21 by the second fixing knob 23, and the top of the folding arm 26 is fixedly installed with a magnetic block 27 corresponding to the fixed post 21.

[0044] As can be seen from the above, the movable sleeve 22 can be easily fixed in a suitable position on the fixed post 21 by the second fixing knob 23, so as to prevent the movable sleeve 22 from sliding up and down. When the folding arm 26 is flipped upward to a vertical state, the magnetic block 27 can contact the fixed post 21. The fixed post 21 is made of metal material, which allows the magnetic block 27 to be attracted to the fixed post 21, so as to easily fix the folding arm 26 and keep the seat mechanism 2 in a folded state, so as to prevent it from unfolding during the carrying process.

[0045] refer to Figure 4 and Figure 5 As shown, the front and rear ends of the support cylinder 29 are hinged to a limit frame 212, and the front and rear ends of the folding arm 26 are fixedly installed with limit stakes 213 that are engaged with the limit frame 212.

[0046] As can be seen from the above, by connecting the limiting frame 212 and the limiting stake 213, the support cylinder 29 and the folding arm 26 can be supported and fixed, so that the support cylinder 29 can support the seat plate 28 and prevent the measuring personnel from shaking or tilting when sitting on the seat plate 28, thus providing stable support for the measuring personnel's sitting posture.

[0047] refer to Figure 4 As shown, the support cylinder 29 is fixed to the support frame 210 by a third fixing knob 211, and a sponge pad 214 is attached to the top of the seat plate 28.

[0048] As can be seen from the above, the support frame 210 can be easily fixed to a suitable length by the third fixing knob 211, which is convenient for supporting according to the height of the seat plate 28. The sponge pad 214 can easily improve the comfort of sitting on the seat plate 28.
