Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1: as shown in fig. 1 to 5, a measure, device of self-checking tower crane straightness that hangs down, including straight board 1, bevel protractor 2 and vertical survey board 3, bevel protractor 2 is fixed to be set up on straight board 1, bevel protractor 2 adopts semicircle bevel protractor, bevel protractor 2 adopts stainless steel's semicircle bevel protractor, bevel protractor 2's straight flange sets up with the lower limb laminating of straight board 1, vertical survey board 3's one end is articulated to be set up in bevel protractor 2's centre of a circle position, vertical survey board 3 can rotate around bevel protractor 2 centre of a circle, vertical survey board 3's lower limb and bevel protractor 2's straight flange laminating setting, vertical survey board 3's lower limb sets up with bevel protractor 2's straight flange laminating simultaneously, vertical survey board 3 and bevel protractor 2 articulated one end fixedly connected with pointer 4.
Preferably, the lower edge of the pointer 4 is arranged in line with the lower edge of the vertical plate 3. And the pointer 4 points to the corresponding angle value when the vertical measuring plate 3 is vertical under the action of gravity.
Preferably, vertical survey board 3 passes through the articulated setting of locating pin 5 and on straight board 1 locating pin 5 can guarantee that vertical survey board 3 and pointer 4 can be stable rotation connection on the bevel protractor.
Preferably, the straight plate 1 and the vertical measuring plate 3 are stainless steel rulers.
Preferably, the angle ruler 2 is fixed on the straight plate 1 by means of glue bonding.
Example 2: in embodiment 1, there is also a problem that the straight plate 1 is not stably attached to the tower crane to be detected during measurement, which affects the measurement accuracy, and therefore, on the basis of embodiment 1, this embodiment further includes: a backing plate 6 is fixedly arranged on one side surface of the straight plate 1 departing from the angle ruler 2. The width of backing plate 6 is less than the width of straight board 1, and the top edge laminating setting of the top edge of backing plate 6 and straight board 1 makes the device establish in the tower crane standard festival outside through backing plate 6 card, has guaranteed the accuracy of inspection result. The backing plate 6 is made of KT plastic.
When carrying out the hang tower straightness measurement of hanging down, place the backing plate 6 laminating tower crane standard festival outside, vertical survey board 3 can keep vertical state under the action of gravity, and the reading of pointer 4 on bevel protractor 2 then is the straightness that hangs down of hang tower this moment.
Calculating the inclination X according to a trigonometric function formula, namely the inclination distance X is the height of the combination tool (the height of the device close to a position point from the top surface of the tower crane foundation) Tg (reading of a bevel rule 2);
firstly, the X is generally less than 0.4 percent under the requirement of the independent height of the tower crane
② when there is a counterfort, X is less than 0.2%
According to the monitoring and control requirements: assuming that the tower crane independent height is set to 40m, the reverse angle 2 reading must be less than 0.229 ° ═ 824.4 ″
