Description

Technical Field

[0001] The utility model specifically relates to a civil engineering measurement device used in engineering sites, belonging to the technical field of civil engineering measurement. Background Art

[0002] All kinds of civil engineering projects need to be measured by measuring devices before, during and after construction in order to achieve accurate construction. Most existing measuring devices use surveying instruments. When measuring, the measuring device needs to be placed horizontally to make the measured value more accurate. The use occasion of the measuring device is often a construction site, so it is difficult to fix the measuring device to a horizontal position, which affects the measurement. For this reason, China Patent Authorization Announcement No.: CN213657876U discloses a civil engineering measuring device for use on-site. When measuring, the measuring device is placed on the ground through a base, and then the horizontal plane and the surface of the visual mirror are observed. The utility model can be judged whether the multiple scale lines are parallel or not, thereby judging whether it is horizontal. Then, when adjustment is needed, the corresponding rotating block can be rotated, and the corresponding moving block can be driven to descend through the rotation of the threaded rod, so that the moving block and the measuring device can be driven to make a slight deflection, so that they slowly approach the horizontal; most of the existing surveying and mapping instruments have the function of adjusting the angle, so that the level of the surveying and mapping end can be automatically adjusted; but the existing surveying and mapping instruments need to be moved to multiple positions and need to adapt to different on-site landforms during on-site measurement. They are only supported by a tripod, which is inconvenient to move and cannot select a suitable measurement method according to the on-site landform. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a civil engineering measurement device for use at the construction site, which can perform single-arm support, triangular high-position support, triangular low-position support and portable support on the surveying instrument, provide a variety of support measurement methods, meet various measurement needs, and improve measurement efficiency.

[0004] The utility model discloses a civil engineering measurement device for use at a construction site, comprising:

[0005] A pedestal, a surveying instrument being installed on the top surface of the pedestal;

[0006] A storage cylinder, wherein a plurality of gripping rods are fixed at intervals on the outer side of the bottom of the storage cylinder and the outer side of the pedestal; a first locking bolt is provided on the storage cylinder;

[0007] A telescopic rod, the top of which is screwed to the inner side of the storage tube; the first locking bolt is screwed to the telescopic rod; a bolt section is fixed to the bottom of the telescopic rod;

[0008] The cylinder seat has a through hole at the center of the bottom of the cylinder seat; an inner card slot is arranged on the inner side of the cylinder seat, and the grip rod and the storage cylinder slide through the inner card slot; a plurality of hinge seats are fixed at intervals on the upper part of the outer cylinder seat, and the cylinder seat has an outer card slot pressed on the lower part of the hinge seat;

[0011] When in use, first unfold the legs. When unfolding, you need to press the bottom of the convex seat to make the connecting plate swing along one side of the convex seat to realize the unfolding of the legs.

Then, through the automatic control of the surveying instrument, realize the horizontal adjustment. After the adjustment is completed, engineering measurement can be carried out. It can be applied to complex environments, such as obstructions on the low side, muddy site, etc.

[0012] When the on-site environment is relatively flat, single-arm support can be used. When using it, first pull down the convex seat to swing the connecting plate along the hinge of the support leg, so that the convex seat is separated from the extension tube, then rotate the support plate to separate the support plate from the telescopic rod, then lift the grip rod to separate the base from the tube seat along the inner slot, then rotate and assemble the support plate and the bottom of the telescopic rod, then adjust the bolts on the telescopic rod to adjust the telescopic rod to the set length, and then lock the position of the telescopic rod; at this time, the surveying instrument can be installed on the top surface of the base, then the horizontality can be adjusted through automatic control of the surveying instrument, and after the adjustment is completed, engineering measurement can be carried out.

[0013] Furthermore, a clamping block is fixed on the support leg, and the clamping block is clamped with the bottom surface of the support plate; when the support leg is stored, the bottom of the support plate is tightened by the clamping block to achieve secondary locking of the support plate.

[0014] Furthermore, a folding groove is provided at the lower part of the grip rod, and a hanging frame is hinged in the folding groove; when the on-site environment is poor and triangular support is not suitable, or the triangular support requires a long adjustment time, the hanging frame can be directly hung on the shoulder, and the third point support on site can be performed through the telescopic rod and the support plate. Then, the horizontality can be adjusted through automatic control of the surveying instrument. After completing one measurement, the telescopic rod is pulled out and directly transported to the next measurement position.

[0015] Furthermore, a positioning foot is screwed onto the bottom of the mounting frame; when the use occasion is a hardened water surface, the mounting frame can be rotated outward and the levelness can be preliminarily adjusted by the positioning foot. Then, the surveying instrument can automatically adjust the levelness to achieve a secondary adjustment. After the adjustment, on-site measurement can be carried out. After completing one measurement, it can be directly sent to the next measurement position through the grip rod. It is easy to carry and adjust, and can improve the measurement efficiency.

[0016] Furthermore, a locking seat is fixed on the outside of the cylinder seat, the support leg is engaged with the locking seat, and the support leg is provided with a locking bolt screwed to the locking seat; before or after measurement, the locking bolt is locked with the locking seat, thereby achieving limit locking of the support leg and the cylinder seat, making it convenient to carry the support leg.

[0017] Compared with the prior art, the civil engineering measuring device of the utility model for use on-site can select a suitable supporting and measuring method in combination with the on-site environment when in use, such as using supporting legs to perform triangular high-position support on the surveying instrument, using telescopic rods and supporting plates for single-arm support, using a hanging frame and adjusting feet for triangular low-position support, and using a hanging frame in combination with a shoulder to achieve portable support, etc., to achieve a variety of supporting and measuring methods, meet various measurement needs, and improve measurement efficiency.
