Further, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
As shown in fig. 1 and 2, the communication tower includes a tower body 100, the tower body 100 includes a tower body 110 capable of being lifted and a communication end 120, the communication end 120 is installed at one end of the tower body 110 for being lifted, so that the height of the communication end 120 is raised by lifting the tower body 110, and the tower body 110 is lifted by sleeving a plurality of section arms as in the prior art, which may cause a problem, because the tower body 100 is temporarily built, during the extending process of the section arms, the connection between the section arms may cause the inclination between the adjacent section arms due to the operation of an operator, or the connection between the later-stage connection may cause the inclination between the adjacent section arms due to the instability of the connection, which may be difficult to determine that the two section arms are inclined by measuring the overall inclination of the tower body 110, and it is impossible to know the inclination angle between the inclined section arms.
Wherein: a measurable space (the space is positioned on one side of the extendable arm, if the present invention has a third-stage arm, that is, three arms are sequentially sleeved, the measurable space of the first-stage arm is positioned on one side of the second-stage arm, the measurable space of the second-stage arm is positioned on one side of the extendable arm, and the measurable space of the third-stage arm is positioned on one side of the extendable arm, but the third-stage arm has no arm extending continuously, so there is no measurable space, so it can be said that the measurable space is positioned on one side of the extendable arm extending out of the next arm), and the inclination angle measuring mechanism 200 is installed in the measurable space by the operator in the later period.
To this end, the present invention provides an inclination measuring device for detection based on a lifting communication tower, which includes an inclination measuring mechanism 200, wherein the inclination measuring mechanism 200 is installed in a measurable space during measurement, as shown in fig. 3 and 4, the inclination measuring mechanism 200 is composed of a support system 210 and a measuring system 220, the support system 210 is fixed in the measurable space, and a support part is provided above the support system 210, the measuring system 220 is mounted on the support part to measure the inclination angle of a projecting section arm, specifically, a point line is formed in the measurable space through the measuring system 220, a point is a measuring base point, and a line is a measuring line, because two adjacent section arms form a cliff in the measurable space (because the section arms are sleeved, the cliff is formed at the joint of the two section arms, because the inclination angle of the projecting section arm is measured, the base point needs to be located on the projecting section arm, and at this time, the measuring line is attached to the projecting section arm, so as to obtain the inclination angle parameter of the projecting section arm, the specific parameter is obtained through a sensor).
It should be noted that the support system 210 is fixed in the measurable space in a detachable manner.
Next, a first embodiment of the present invention is shown by fig. 5, 6, 8 and 9,
fig. 5 discloses a support system 210, wherein the support system 210 comprises an upper clamping plate 211 and a lower clamping plate 212, the upper clamping plate 211 and the lower clamping plate 212 are rotatably connected, which can be realized in a hinged manner, an upper fingerplate 213 is arranged on the upper clamping plate 211 at one side of the rotatable connection, a support 214 is arranged on the lower clamping plate 212 at one side of the rotatable connection, and a clamping space 210A formed between the upper clamping plate 211 and the lower clamping plate 212 is opened by pressing the upper fingerplate 213.
The upper clamping plate 211 and the lower clamping plate 212 are arranged to be semi-arc structures, when the upper clamping plate 211 and the lower clamping plate 212 are closed, a clamping space 210A with a circular cross section is formed, and the embodiment is suitable for the section arms built by the column structures with uniform specifications.
However, in the practical process, the specification of the columnar structure is difficult to be unified, and another embodiment needs to be provided at this time, namely, the upper clamping plate 211 and the lower clamping plate 212 are set to be non-semicircular arc structures, so that the columnar structure smaller than the arc radius can realize clamping, even if the specification is different, the clamping fixing capacity is reduced compared with the semi-arc structure.
The upper clamping plate 211 and the lower clamping plate 212 can also be arranged in a straight plate structure, so that the use of the section arm with the square main body part can be adapted.
Further, a rubber layer may be provided on the inner surfaces of the upper and lower clamping plates 211 and 212 to increase friction with the contact surface at the time of clamping, thereby achieving an increase in fixing ability.
The supporting member 214 in this embodiment includes a lower finger plate 214b, the lower finger plate 214b is fixed to a side where the lower plate 212 is rotatably connected to the upper plate 211, and the supporting portion is an outer surface of the upper plate 211.
Fig. 6 discloses a measuring system 220, wherein the measuring system 220 comprises a measuring arm 221, a base point arm 222 and a connecting arm 223, the measuring arm 221 and the base point arm 222 are rotatably connected, the base point arm 222 and the connecting arm 223 are rotatably connected, the connecting arm 223 is mounted on a supporting part, the mounting mode can be fixed mounting or detachable mounting, and is preferably detachable mounting, so that the measuring system is convenient to carry and convenient to replace a bad party, and angle sensors are mounted at the switching part of the measuring arm 221 and the base point arm 222 and the switching part of the base point arm 222 and the connecting arm 223 to measure the rotating angles of the corresponding arm bodies, namely the measuring arm 221 and the base point arm 222.
When the measuring device is used, the measuring system 220 on the supporting part is installed on the first-stage arm in a measurable space through the upper clamping plate 211 and the lower clamping plate 212 (namely, the inclination angle of the second-stage arm needs to be measured at the moment, if the inclination angle of the third-stage arm is measured, the measuring system 220 needs to be installed on the second-stage arm, and the like), and the state of the supporting part needs to be adjusted by a level gauge during installation, so that the supporting part is kept horizontal;
then, with reference to fig. 8 and 9, the base point arm 222 is rotated to be attached to the secondary arm and a base point is formed at the attachment point, and at this time, a measurement coordinate system B is established with the base point, so that the rotation angle of the measurement line is measured by using the re-established measurement coordinate system B, and thus the extended arm, that is, the secondary arm, can be measured, and the problem that the inclination angle between the two arms is difficult to measure is solved, and the base point arm 222 and the horizontal axis where the connecting arm 223 is connected to each other form a base coordinate system a in the upward direction, and the measurement coordinate system B and the base coordinate system a combine to form a dual coordinate system in which the angle is formed by the base coordinate system a, and the angle is formed by the base coordinate system a in the present embodiment because the secondary arm is extended to form a cliff, and the base coordinate system a corresponds to the angle sensor installed at the connection point of the base point arm 222 and the connecting arm 223, and the angle sensor measures the angle formed by rotating counterclockwise from the horizontal line as a starting point, that is a4 in fig. 9;
then, with reference to fig. 8 and 9, the measuring arm 221 is rotated to be attached to the secondary arm, and at this time, the measuring angle of the measuring line in the coordinate system B is measured, specifically, the measuring angle is measured by the angle sensor installed at the junction of the measuring arm 221 and the base arm 222, and the measuring manner of the angle sensor is an angle formed by clockwise/counterclockwise rotation with the axial direction of the base arm 222 as a starting point, that is, a1 in fig. 9;
finally, referring to fig. 9, it can be seen from the principle that the stagger angles between two parallel lines are equal: a3= a4, since a3 and a4 are mutually staggered angles, and a1= a2+ a3, where a2 is a comparison angle, it can be deduced that a2= a1-a4, at which time both a1 and a4 can be measured, so a2 can also be calculated, and the resultant a2 is compared with a 90-degree angle, where:
a2=90 °, it means that the secondary arm is not tilted with respect to the primary arm;
a2 ≠ 90 °, which means that the secondary arm is tilted with respect to the primary arm, the tilt angle and direction being given by a2-90, for example: a2=100, then 100-90=10, at which time it can be concluded that the secondary arm is inclined 10 degrees in the counterclockwise direction with respect to the primary arm; a2=80, then 80-90= -10, which may result in the arm of the second stage being tilted 10 degrees clockwise with respect to the arm of the first stage.
In addition, in order to ensure the stability of the segment arm to which the measuring arm 221 and the base point arm 222 are attached, as shown in fig. 6, a magnetic attraction plate 224 is provided on the side of the segment arm to which the measuring arm 221 is attached, and the magnetic attraction plate 224 can attract the segment arm when the measuring arm 221 is attached to the segment arm, so that the stability of the connection of the upper plate 211 is improved, and the base point arm 222 is naturally stabilized after the measuring arm 221 is stabilized.
Moreover, the magnetic attraction plate 224 can also attract the base point arm 222 or the lower clamp plate 212, and if the connecting arm 223 is fixedly mounted on the supporting portion, the magnetic attraction plate 224 can attract the lower clamp plate 212, so that the magnetic attraction plate 224 attracts the lower clamp plate 212 to prevent the measuring arm 221 and the base point arm 222 from swinging, and thus the portable measuring device is convenient to carry;
if the connecting arm 223 can be detached, the measuring arm 221 and the base point arm 222 are overlapped, so that the magnetic attraction plate 224 attracts the base point arm 222, and the connecting arm is also convenient to carry.
In a second embodiment of the present invention, the first embodiment,
in this embodiment, another embodiment of the supporting member 214 is disclosed, in which the supporting system 210 is composed of an upper plate and a lower plate, and the upper plate and the lower plate are provided with bolt structures, a clamping space 210A is formed between the upper plate and the lower plate, the clamping space 210A is sleeved outside the main body of the arm segment, then the upper plate and the lower plate are attached to the main body of the arm segment, and then the bolt structures are tightened, so that the main body of the arm segment can be clamped.

Figure 10 shows a third embodiment of the invention,
with respect to the two embodiments described above, in this embodiment, the inclination angle of the communication tower is not measured, but the slope gradient is measured, B3 in fig. 10 is the angle that can be measured by the base coordinate system a, in this embodiment, the angle that the slope forms refers to the angle that the slope forms, and B1 is the measured angle that can be measured by the measuring coordinate system B, and similarly, since B2 and B3 are stagger angles, B2= B3, and the inclination angle c of the slope is relative to the horizontal, c = B1+ B2, and c = B1+ B3 can be derived, and B1 and B3 can be measured, so the inclination angle c of the slope can also be calculated.
In the embodiment, because the support system 210 is not required to be clamped, but the support system 210 needs to be placed on a horizontal plane smoothly, for this reason, the support system 210 shown in fig. 7 is disclosed in the embodiment, the support system 210 includes an upper clamp plate 211 and a lower clamp plate 212, the upper clamp plate 211 and the lower clamp plate 212 are also connected in a rotating manner, and an upper fingerboard 213 is fixed on one side where the upper clamp plate 211 is connected with the lower clamp plate 212;
