Description

TECHNICAL FIELD

[0001] The application relates to the technical field of engineering surveying, in particular to a construction engineering supervision engineering surveying device. BACKGROUND

[0002] In the supervision process of a construction project, surveying work is a key quality control link. The surveying precision directly affects the design implementation effect and construction quality of the project.

[0003] The construction engineering supervision engineering surveying device comprises a placing rack and a surveying main body. In the storage and transportation process of the construction engineering supervision engineering surveying device, foam is usually used to protect the lens of the surveying instrument, and before the construction engineering supervision engineering surveying device is used, the foam needs to be removed from the surveying instrument, and then the construction engineering supervision engineering surveying device is placed on the ground. According to the above related technology, the inventors consider that the lens of the surveying instrument cannot be protected when the construction engineering supervision engineering surveying device is placed on the ground and the surveying instrument is not used for surveying. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problem that the lens of the surveying instrument cannot be protected when the construction engineering supervision engineering surveying device is placed on the ground and the surveying instrument is not used for surveying, the application provides a construction engineering supervision engineering surveying device.

[0005] The construction engineering supervision engineering surveying device provided by the application adopts the following technical scheme:

[0006] The construction engineering supervision engineering surveying device comprises a placing rack and a surveying main body. The top of the placing rack is provided with a placing table for arranging the surveying main body. A protection frame for protecting the surveying main body is installed at the placing table. The top of the placing table is provided with a circular boss. The protection frame comprises a rotating sleeve rotatingly arranged outside the circular boss and two protection side plates symmetrically connected to the top of the rotating sleeve. A surveying gap is formed between the two protection side plates. The protection frame has a first station and a second station when rotating on the placing table. When the protection frame is in the first station, the lens of the surveying main body is opposite to the surveying gap. When the protection frame is in the second station, the lens of the surveying main body is opposite to the protection side plates.

[0007] By adopting the technical scheme, when the placing rack stands on the ground and when measurement by the measurement main body is needed, the measurement gaps of the two protective side plates are made to face the lens of the measurement main body by rotating the protective side plates, so that measurement by the measurement main body can be performed; when measurement by the measurement main body is not needed, the protective side plates are made to face the lens of the measurement main body by rotating the protective frame, so that protection of the lens of the measurement main body can be achieved.

[0008] Optionally, a limiting ring groove is formed in the outer side wall of the circular boss in the circumferential direction, an inner wall of the rotating sleeve is provided with a rotating sliding block arranged in the limiting ring groove, a bottom surface of the rotating sliding block is provided with a rotating ball groove, and a rotating ball is rotatably arranged in the rotating ball groove.

[0009] By adopting the technical scheme, the cooperation of the limiting ring groove and the rotating sliding block can reduce the probability that the rotating sleeve is separated from the circular boss during rotation. The cooperation of the rotating ball groove and the rotating ball enables the rotating ball to abut against the bottom surface of the limiting ring groove during rotation of the rotating sleeve, which helps to improve the fluency of the rotating sleeve during rotation.

[0010] Optionally, the rotating sleeve is provided with a mounting through hole penetrating through the inner and outer surfaces, and the rotating sleeve is provided with a locking bolt threadedly matched with the rotating sliding block at the mounting through hole.

[0011] By adopting the technical scheme, the rotating sliding block is connected and fixed with the rotating sleeve through the locking bolt, and the rotating sleeve can be detachably mounted on the placing table by unscrewing the locking bolt from the rotating sliding block.

[0012] Optionally, a limiting convex ring is arranged on the top of the rotating sleeve and abuts against the top surface of the circular boss, the top surface of the circular boss is provided with a plunger hole, a ball head spring plunger is arranged in the plunger hole, a first limiting hole and a second limiting hole for clamping a plunger ball of the ball head spring plunger are arranged on the bottom surface of the limiting convex ring, the protective frame is in a first station when the plunger ball of the ball head spring plunger is clamped in the first limiting hole, and the protective frame is in a second station when the plunger ball of the ball head spring plunger is clamped in the second limiting hole.

[0013] By adopting the above technical solution, by setting a ball-head spring plunger on the circular boss and setting a first limiting hole and a second limiting hole on the bottom surface of the limiting ring, the cooperation between the first limiting hole and the plunger ball of the ball-head spring plunger ensures that the protective frame has ideal stability when it is in the first working position, and the measuring gap can be kept directly aligned with the lens of the measuring body; the cooperation between the second limiting hole and the plunger ball of the ball-head spring plunger ensures that the protective frame has ideal stability when it is in the second working position, and the protective side plate can be kept directly aligned with the lens of the measuring body.

[0014] Optionally, the protective frame is further provided with a connecting top plate connecting the tops of the two protective side plates; the outer side wall of the protective side plate is provided with an adjustment handle.

[0015] By adopting the above technical solution, the top plate connection allows the other protective side plate to rotate simultaneously when one protective side plate is rotated. The adjustment handle makes it easier to rotate the protective frame.

[0016] Optionally, the width of the connecting top plate is smaller than the width of the protective side plate.

[0017] By adopting the above technical solution and limiting the width of the connecting top plate and the protective side plate, the field of view of the measuring subject is improved when measuring through the lens of the measuring subject.

[0018] Optionally, the protective side plate is further provided with a protective component; the protective component includes an adjusting rod threaded through the protective side plate and a protective cover installed at the end of the adjusting rod for covering the lens of the measuring body.

[0019] By adopting the above technical solution, when the protective frame is in the second position, the protective cover moves toward the lens of the measuring subject by rotating the adjustment rod, thereby covering the lens of the measuring subject and helping to reduce the probability of the lens of the measuring subject being scratched.

[0020] Optionally, the protective assembly further includes an adjusting handwheel mounted on the other end of the adjusting rod.

[0021] By adopting the above technical solution, the adjustment handwheel is designed to make it easier for users to turn the adjustment lever.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. A construction engineering supervision engineering surveying device, by installing a protective frame on a placing table, when measurement is needed, by rotating the protective frame to make the measurement gap opposite the lens of the measurement main body, so as to realize measurement; when measurement is not needed, by rotating the protective frame to make the protective side plate opposite the lens of the measurement main body, so as to realize protection of the lens of the measurement main body.

[0024] 2. By setting a ball head spring plunger on the circular boss and setting a first limiting hole and a second limiting hole on the limiting convex ring, cooperation of the plunger ball of the ball head spring plunger with the first limiting hole makes the stability of the protective frame in the first station ideal, and cooperation of the plunger ball of the ball head spring plunger with the second limiting hole makes the stability of the protective frame in the second station ideal.
