Description
Technical Field
[0001] The utility model relates to the technical field of surveying and mapping, in particular to a bracket-type surveying and mapping leveling rod. Background Art
[0002] A surveying level rod is a measuring tool used in engineering surveying and topographic mapping. Existing surveying level rods are generally mounted on a bracket, which is supported by a movable bracket.
[0003] The existing bracket generally includes a top plate and a plurality of supporting legs arranged below the top plate. The top plate is used to install the surveying level. After the supporting legs and the top plate support the level body above the ground, the level body is in a suspended state. In order to maintain the stability of the measurement reference surface or when measuring the elevation of buildings, bridges, etc., it is necessary to adjust the level according to the height of the object to be measured to ensure the accuracy of the measurement results. The existing technology generally achieves this by adjusting the positions of multiple supporting legs. However, the existing technology's method of adjusting the height and position of the surveying level is relatively simple. Adjusting the height of the surveying level requires frequent adjustment of multiple supporting legs, which results in large errors and inconvenient adjustment methods. In addition, the measuring range of the surveying level is limited, and it cannot be adaptively adjusted according to the height and position of the object to be measured, affecting the accuracy of the measurement results. Utility Model Content
[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a bracket-type surveying and mapping leveling rod.
[0005] The technical solution of this utility model is as follows:
[0006] A bracket-type surveying and mapping level ruler comprises a base and a plurality of support legs hinged to the base, a vertical column is provided through the middle of the base, the height of the column on the base is adjustable, and a clamping mechanism is detachably connected to the upper portion of the column;
[0007] The clamping mechanism includes a clamping frame and a first locking member. One side of the clamping frame is detachably connected to the upper end of the column through a quick-release assembly. The clamping frame is provided with a through-hole in the vertical direction. The surveying and mapping level rod is detachably connected to the plug-in hole. One end of the first locking member passes through the clamping frame and is tightened to the outer surface of the surveying and mapping level rod.
[0008] The quick-release assembly includes a locking block and a locking shell clamped thereon. The locking block is connected to the upper end of the column, and the locking shell is connected to one side of the clamping frame. The angular position of the locking shell and the locking block is adjustable, and the locking block and the locking shell are plug-connected by a second locking piece.
[0009] The surveying level rod is vertically inserted into the clamping frame of the clamping mechanism. The first locking member can finely adjust the height position of the surveying level rod in the clamping frame and cooperate with the up-and-down coarse adjustment of the column on the base to drive the surveying level rod to move up and down. By means of coarse adjustment and fine adjustment of the height position of the surveying level rod, it can be adaptively adjusted according to the different heights of the measured object, which is convenient for measurement and the accuracy of measurement data. Moreover, the front-back or left-right position of the surveying level rod is adjustable, and the position of the surveying level rod can be adjusted without moving the support legs.
[0010] The specific structure of the above-mentioned clamping frame is that the clamping frame includes a vertical plate and a component placement frame. The vertical plate is vertically arranged above the locking shell, and the vertical plate is connected to the component placement frame through a cross bar. The insertion opening is provided on the component placement frame.
[0011] To facilitate the first locking member to have a good clamping effect on the surveying level rod and not cause damage to the outer surface of the surveying level rod, an anti-slip member is provided on one outer side of the surveying level rod close to the cross bar. The anti-slip member is arranged along the length direction of the surveying level rod, and one end of the first locking member can pass through the clamping frame and abut against one side of the anti-slip member.
[0012] The specific structure of the above-mentioned anti-slip member is that the length of the anti-slip member is greater than the length of the insertion opening in the vertical direction, so that when the surveying level rod moves up and down within a certain range in the insertion opening, the first locking member can be pressed against the anti-slip member on one side of the surveying level rod; the length of the anti-slip member is 1 / 3 - 2 / 3 of the length of the surveying level rod, which can ensure that the anti-slip member can correspond to the first locking member within a large moving range of the surveying level rod.
[0013] Regarding the specific structure for the column to be able to adjust its height on the base, a third locking member is threadedly connected to one side of the base along the direction perpendicular to the column. The column is provided with a plurality of adjustment holes along its length direction, and one end of the third locking member can pass through the base and be inserted into the adjustment holes.
[0014] The specific connection structure of the above-mentioned locking block and the locking shell is that the locking block and the locking shell are correspondingly provided with through holes, and the through holes are toothed insertion holes. The axial direction of the toothed insertion holes is perpendicular to the vertical plane where the insertion opening is located. The second locking member is a toothed insertion bar adapted to it, and its length is greater than the length of the toothed insertion hole. By such a setting, when the toothed insertion bar is pulled out, the locking shell can be rotated by a certain angle to adjust the position of the surveying level rod without moving multiple support legs as a whole.
[0015] Regarding the structure of the contact surface between the locking block and the locking shell, the locking block is a spherical structure, and the lower surface of the locking shell is an arc surface adapted to the locking block, which is convenient for the locking shell to drive the clamping frame and the surveying level rod thereon to adjust the position.
[0016] The beneficial effects of the present utility model are as follows:
[0017] Adjusting the height position of the column in the base through the third locking member can play a role in roughly adjusting the surveying level installed on the upper part of the column. Combining with the adjustment of the height position of the surveying level in the clamping bracket by the first locking member, the height position of the surveying instrument body can be finely adjusted. Through the combination of rough adjustment and fine adjustment methods, the surveying level can be accurately adjusted to the preset height position, realizing adaptive adjustment according to the height of the measured object and ensuring the accuracy of the measurement results;
[0018] By setting a quick-release component, the quick-release component is used to quickly connect or disassemble the column and the clamping bracket, and is also used to quickly adjust the position of the clamping bracket and the surveying level thereon in the front-back or left-right direction, and the position of the surveying level can be adjusted without moving multiple support legs.

[0031] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, a bracket-type surveying level staff includes a base 1 and a plurality of support legs 3 hinged to the base 1. The upper end of the support leg 3 is a hinge end 2, which is hinged to the outside of the base 1 through the hinge end 2. The plurality of support legs 3 are arranged at equal intervals. A vertical hole is provided in the middle of the base 1, and a column 4 is inserted into the vertical hole. A plurality of adjustment holes 401 are arranged along the length direction of the column 4. A third locking member 5 is threadedly connected to one side of the base 1 in a direction perpendicular to the column 4. The third locking member 5 can be a plug rod. One end of the third locking member 5 can pass through the base 1 and be inserted into the corresponding adjustment hole 401, so that the height of the column 4 on the base 1 is adjustable. A clamping mechanism is detachably connected to the upper part of the column 4.
[0032] See Figure 2 and Figure 3 As shown, among them, the above-mentioned clamping mechanism includes a clamping frame and a first locking member 15. The clamping frame includes a vertical plate 11 and a component placement frame 13. The vertical plate 11 is vertically arranged above the locking shell 8. The vertical plate 11 is connected to the component placement frame 13 through two parallel cross bars 12. The component placement frame 13 is a vertically arranged rectangular long block. One side of the vertical plate 11 is detachably connected to the upper end of the column 4 through a quick-release component. The vertical plate 11 and the column 4 are both vertically arranged and located in the same vertical plane, which is convenient for determining the position of the component placement frame 13 and the surveying level staff 6 thereon. The component placement frame 13 is provided with a through insertion interface in the vertical direction. The surveying level staff 6 is detachably connected to the insertion interface. One end of the first locking member 15 passes through the clamping frame and abuts against the outer surface of the surveying level staff 6. Tightening the first locking member 15 can squeeze the surveying level staff 6 in the insertion interface to play a fixing role. Loosening the first locking member 15 can adjust the position of the surveying locking member.
[0033] See Figure 3As shown in the figure, to facilitate the first locking member 15 to have a better clamping effect on the surveying level rod 6 and not cause damage to the outer surface of the surveying level rod 6, an anti-slip member 14 is provided on an outer side surface of the surveying level rod 6 close to the cross bar 12. The anti-slip member 14 is arranged along the length direction of the surveying level rod 6. One end of the first locking member 15 passes through the clamping bracket and can abut against one side of the anti-slip member 14. The specific structure of the anti-slip member 14 is that the length of the anti-slip member 14 is greater than the length of the insertion port in the vertical direction, so that when the surveying level rod 6 moves up and down within a certain range in the insertion port, the first locking member 15 can be pressed against the anti-slip member 14 on one side of the surveying level rod 6; the length of the anti-slip member 14 is 1 / 3 - 2 / 3 of the length of the surveying level rod 6. In this embodiment, the length of the anti-slip member 14 is preferably 2 / 3 of the length of the surveying level rod 6. This length is located at the middle position on one side of the surveying level rod 6, and can ensure that the anti-slip member 14 can correspond to the first locking member 15 within a relatively large moving range of the surveying level rod 6.
[0034] See Figure 6 and Figure 7 As shown in the figure, the quick-release assembly includes a locking block 16 and a locking shell 8 clamped thereon. The locking block 16 is connected to the upper end of the column 4 through a bearing seat 7, and the locking shell 8 is connected to the vertical plate 11 through a support seat 10. The angular position between the locking shell 8 and the locking block 16 is adjustable, and the locking block 16 and the locking shell 8 are connected by inserting a second locking member 9.
[0035] See Figure 7 , Figure 8 and Figure 9 As shown in the figure, the specific connection structure between the above-mentioned locking block and the locking shell 8 is that the locking block 16 and the locking shell 8 are respectively provided with through holes, and the through holes are toothed insertion holes 17. The toothed insertion hole 17 includes a circular hole and a plurality of tooth grooves equally spaced along the outer circumference of the circular hole. The two ends of the tooth grooves are also through settings, and a plurality of tooth grooves are all communicated with the circular hole. The cross-section of the toothed insertion hole 17 close to the outside is in the shape of a gear cross-section. The axial direction of the toothed insertion hole 17 is perpendicular to the vertical plane where the insertion port is located. The second locking member 9 is a toothed insert strip adapted to it. The cross-section of the toothed insert strip is in the shape of a gear cross-section adapted to the toothed insertion hole 17, and its length is greater than the length of the toothed insertion hole 17. The toothed insert strip is inserted into the toothed insertion hole 17. By setting like this, when the toothed insert strip is pulled out, the locking shell 8 can be rotated by a certain angle, and then the toothed insert strip is aligned with the toothed insertion hole 17, and the toothed insert strip is inserted into the toothed insertion hole 17 to adjust the position of the surveying level rod 6. Compared with the prior art that requires the overall movement of the support legs 3 inserted into the ground, in this embodiment, it is not necessary to move the plurality of support legs 3 as a whole, and the adjustment method is relatively fast. Regarding the structure of the contact surface between the locking block and the locking shell, the locking block is a spherical structure, and the lower surface of the locking shell 8 is an arc surface adapted to the locking block, which is convenient for the locking shell to drive the clamping bracket and the surveying level rod 6 thereon to adjust the position.
[0036] The functions that the above structure can achieve are as follows: The survey leveling staff 6 is vertically inserted into the clamping frame of the clamping mechanism. The first locking member 15 can finely adjust the height position of the survey leveling staff 6 in the clamping frame, and cooperate with the up-and-down coarse adjustment of the column 4 on the base 1 to drive the survey leveling staff 6 to move up and down. By means of coarse adjustment and fine adjustment of the height position of the survey leveling staff 6, it can be adaptively adjusted according to the different heights of the measured object, which is convenient for measurement and the accuracy of measurement data. Moreover, the front and rear positions of the survey leveling staff 6 are adjustable. In the prior art, when adjusting the front and rear positions of the survey leveling staff, it is necessary to pull out the support legs inserted into the ground, which is rather troublesome. In this embodiment, the position of the survey leveling staff 6 can be adjusted without moving the support legs 3.
