When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figures 1 to 6 In an embodiment of the present invention, a device for detecting the verticality of the guide rail frame installation of a construction elevator includes a triangular base frame 1, three sets of leveling components arranged at three corners of the triangular base frame 1, and a distance measuring mechanism arranged at the center above the triangular base frame 1;

[0032] The distance measuring mechanism includes a triangular prism 2 vertically fixed at the center above the triangular base frame 1, a lifting component movably arranged on the triangular prism 2, and a horizontal deviation measuring component arranged on the top of the lifting component;

[0033] A manual adjustment structure connected to the lifting assembly for driving the lifting assembly to move vertically along the triangular prism sleeve 2 is installed on one side of the triangular prism sleeve 2. The manual adjustment structure is connected to the horizontal deviation measuring assembly through a transmission assembly. When the manual adjustment structure drives the lifting assembly to move vertically along the triangular prism sleeve 2, the transmission assembly drives the horizontal deviation measuring assembly to extend in the horizontal direction.

[0034] In an embodiment of the present invention, the orientation of the tripod base frame 1 is adjusted by a leveling assembly so that the tripod base frame 1 is in a horizontal position, which can be suitable for bumpy ground in different scenarios; the lifting assembly is driven to rise upward by a manual adjustment structure, and at the same time, the manual adjustment structure drives the horizontal deviation measuring assembly to extend in the horizontal direction through the transmission assembly. When the horizontal deviation measuring assembly touches the guide rail frame of the construction elevator, the tangent or cotangent value of the measured horizontal distance and the vertical distance is calculated to obtain the verticality deviation value.

[0035] As an embodiment of the present invention, the manual adjustment structure includes a turntable 8 rotatably arranged on one side of the triangular prism 2, a first bevel gear 9 is fixed to one side of the turntable 8, and the first bevel gear 9 is connected to a driven rod 11 rotatably arranged on the outer wall of the triangular prism 2 through a second bevel gear 10;

[0036] The driven rod 11 is respectively connected to the lifting assembly and the transmission assembly.

[0037] In the embodiment of the present invention, the first bevel gear 9 can be driven to rotate by manually rotating the turntable 8, and the first bevel gear 9 drives the driven rod 11 to rotate with the help of the second bevel gear 10. When the driven rod 11 rotates, it drives the lifting component to move while also using the transmission component to drive the horizontal deviation measuring component to move, thereby realizing the function of synchronously measuring height and horizontal distance.

[0038] As an embodiment of the present invention, the lifting assembly includes a lead screw 18 rotatably arranged in the center of the triangular prism sleeve 2, a lifting column 7 vertically slidably arranged in the triangular prism sleeve 2 and threadedly connected to the lead screw 18, and a second transmission member 17 for connecting the driven rod 11 and the lead screw 18;

[0039] The horizontal deviation measuring assembly is installed on the top of the lifting column 7, and the driven rod 11 is a hollow tube. Of course, a through hole is opened on the outer wall of the triangular sleeve column 2 for the second transmission member 17 to pass through.

[0040] In the embodiment of the present invention, when the driven rod 11 rotates, the second transmission member 17 is used to drive the screw 18 to rotate. The rotating screw 18 drives the lifting column 7 to slide upward along the inner wall of the triangular prism sleeve 2, thereby driving the horizontal deviation measuring component to move upward.

[0041] As an embodiment of the present invention, the horizontal deviation measuring assembly includes a reel 14 fixed on the top of the lifting column 7, a reel groove 20 spirally opened at the center of the reel 14, and a steel tape measure 16 arranged in the reel groove 20;

[0042] The fixed end of the steel tape measure 16 is connected to the transmission assembly via a snap-fit ​​structure.

[0043] In the embodiment of the present invention, when the driven rod 11 rotates, the transmission assembly cooperates with the engaging structure to drive the steel tape measure 16 to be released from the winding groove 20 on the reel 14 or to be wound into the winding groove 20 on the reel 14 .

[0044] As an embodiment of the present invention, the transmission assembly includes a transmission rod 12 rotatably arranged on the lifting column 7 and cooperating with the driven rod 11, a reel 15 passing through the reel 14 and connected to the steel tape measure 16, and a first transmission member 13 for connecting the reel 15 and the transmission rod 12;

[0045] A cavity is provided at the center of the upper portion of the lifting column 7, the reel 15 is rotatably disposed in the cavity, and the upper portion of the reel 15 passes through the bottom of the reel 14 and is rotatably connected thereto, a hole is provided on the lifting column 7 for the No. 1 transmission member 13 to pass through, and a coaxial structure is also provided between the transmission rod 12 and the driven rod 11.

[0046] In the embodiment of the present invention, when the driven rod 11 rotates, the coaxial structure is used to drive the transmission rod 12 to follow the rotation. It should be noted that the setting of the coaxial structure can make the transmission rod 12 slide along the axis of the driven rod 11. Therefore, when the lead screw 18 drives the lifting column 7 to move vertically, although the lifting column 7 drives the transmission rod 12 to follow the lifting, it does not affect the rotation of the transmission rod 12 driven by the driven rod 11.

[0047] The transmission rod 12 drives the reel 15 to rotate with the help of the first transmission member 13 , and the reel 15 cooperates with the engaging structure to drive the steel tape measure 16 to be released from the reel 14 or put into the reel 14 .

[0048] As an embodiment of the present invention, the coaxial structure includes a fillet formed on the inner wall of the driven rod 11 and a ridge fixed on the outer wall of the transmission rod 12, and the ridge is slidably engaged in the fillet.

[0049] In the embodiment of the present invention, since the insert strip and the ridge are provided, the transmission rod 12 can be driven to rotate when the driven rod 11 rotates, and the transmission rod 12 can also move up and down along the axis of the driven rod 11 without affecting the transmission between the two.

[0050] As an embodiment of the present invention, the locking structure includes a locking groove 23 arranged on one side of the upper part of the reel 15, a locking tooth 22 fixed to one end of the steel tape measure 16 close to the center of the reel 14, and a through groove 21 opened on the reel 14 for the locking tooth 22 to pass through, and a top cover 19 is fixed on the top of the reel 15.

[0051] In the embodiment of the present invention, when the reel 15 rotates, the latching teeth 22 are driven to make spiral motion in the reel groove 20 through the latching groove 23, thereby releasing the steel tape measure 16 from the reel groove 20 on the reel 14 or collecting it into the reel groove 20. The top cover 19 is provided to prevent the steel tape measure 16 from detaching from the upper part of the reel groove 20.

[0052] As an embodiment of the present invention, the leveling assembly includes a sleeve shaft 3 that passes through and is fixed on the three corners of the triangular base frame 1, a screw rod 5 that is rotatably arranged on the sleeve shaft 3, a foot sleeve 4 that is threadedly connected to the lower part of the screw rod 5, and a telescopic column 6 that is fixed on both sides of the foot sleeve 4 and vertically slides with the triangular base frame 1.

[0053] In the embodiment of the present invention, rotating the screw rod 5 can make the foot cover 4 move up and down under the constraint of the telescopic columns 6 on both sides, so that the heights of the three corners of the triangular frame 1 can be adjusted individually until the triangular frame 1 is in a horizontal position, so that the device can adapt to ground foundations with different degrees of potholes.
