Specifically, the surveying and mapping frame for construction further comprises a first hydraulic cylinder, wherein the first hydraulic cylinder is used for driving the limiting rod 217 to slide in a direction perpendicular to the first hydraulic cavity 206 and the second hydraulic cavity 207, and locking of the limiting rod 217 to the first hydraulic cavity 206 and the second hydraulic cavity 207 is released.
In the present embodiment, the first hydraulic chamber 206 and the sliding block 208 and the second hydraulic chamber 207 and the sliding block 208 are connected by return springs. Not identified in the drawing, after the first locking member locks the support plate 130 with the first rotating plate 202, the first hydraulic cylinder drives the limiting member to release the limitation of the first hydraulic cavity 206 and the second hydraulic cavity 207, and the return spring resets the driving sliding block 208, so that the sliding block 208 returns to the initial state, and the first positioning block 210 is not pressed any more.
By combining the above embodiments, the specific working principle and working process are as follows:
in use, the base 110 is placed on the ground, and then the positioning rod 218 is pulled out to unlock the first rotating plate 202 and the supporting plate 130, and when the base 110 tilts around the third reference axis along the first rotation direction, the first rotating plate 202 is caused to rotate, so that the relative position of the first rotating plate 202 and the supporting plate 130 is changed, and the first rotating plate 202 is caused to rotate to a direction perpendicular to the tilting direction.
While the first rotating plate 202 rotates, if the base 110 is tilted to compress the hydraulic oil in the first hydraulic rod 204, the first hydraulic rod 204 is communicated with the first hydraulic chamber 206. The hydraulic oil in the first hydraulic rod 204 is compressed to the first hydraulic cavity 206, so that the first hydraulic cavity 206 has a stretching trend, and since the first hydraulic cavity 206 and the second hydraulic cavity 207 are initially limited by the limiting rod 217 and cannot move in the radial direction of the support plate 130, the first hydraulic cavity 206 causes the sliding block 208 to slide in the radial direction of the support plate 130, so that the sliding block 208 pushes the first positioning block 210 to move, and further drives the driven gear 214 to move, so that the driven gear 214 is meshed with the first driving gear 215.
Then, the positioning rod 218 is inserted downwards from the first through hole, after the positioning rod 218 is inserted downwards from the first through hole, an operator manually pushes the positioning rod 218 to rotate, the positioning rod 218 rotates to drive the supporting plate 130 to synchronously rotate until the supporting plate 130 rotates to a position parallel to the first rotating plate 202 again, at this time, the positioning rod 218 can pass through the second through hole 219 to lock the supporting plate 130 and the first rotating plate 202, and after the first rotating plate 202 rotates to a direction perpendicular to the tilting direction, the supporting plate 130 is used to drive the connecting platform 140 to rotate to a direction perpendicular to the tilting direction.
Then, the first motor is started to drive the first driving gear 215 to start, the driven gear 214 is driven to rotate reversely by forward rotation of the first driving gear 215, and the connecting platform 140 can be driven to rotate reversely and anticlockwise by rotation of the driven gear 214.
I.e., when the base 110 is tilted about the third reference axis in a clockwise direction of rotation, here clockwise, the first direction of rotation, the first hydraulic stem 204 is compressed and the connecting platform 140 is rotated in the opposite direction of the first direction of rotation, i.e., counter-clockwise. After the connection platform 140 rotates a first preset angle in the reverse direction of the first turn, the alarm does not sound any more at this time and stops the first motor.
The mapping may then begin by mounting the mapping instrument on the connection platform 140. After the mapping is completed, the first hydraulic cylinder is started, the limiting rod 217 is driven to slide on the supporting plate 130, limiting on the first hydraulic cavity 206 and the second hydraulic cavity 207 is released, the sliding block 208 is driven to return by the return spring, the sliding block 208 returns to the initial state, the first positioning block 210 is not extruded any more, and the driven gear 214 is not meshed with the first driving gear 215 any more.
