Description

Technical Field

[0001] The present application relates to the technical field of verticality detection equipment, and in particular to a verticality adjustment device for a power line pole vehicle and an adjustment method thereof. Background Art

[0002] Utility poles are the main facilities supporting power transmission and distribution lines. They can arrange electric wires in every corner and provide stable electricity to the people. To ensure the safe and stable operation of power lines, utility poles must be perpendicular to the ground during the assembly process.

[0003] In the related art, a Chinese patent with application number CN201410581948.0 proposes a reinforced concrete pole vertical measuring instrument and a method for correcting a pole using the measuring instrument. The vertical measuring instrument includes a level body with a level, and a detachable pad is arranged on the side of one end of the level body, and the ratio of the horizontal thickness of the pad to the height of the level body is 1:75. Because the taper of the standard tapered rod is 1 / 75, the pad is installed on the side of the end of the level body, the end of the level body with the pad is upward, and the side with the pad is attached to the side of the pole, and the pole is adjusted according to the indication of the level at the top, so that the level indicates zero scale; the level body is moved 90 degrees along the circumference of the pole, and the pole is adjusted according to the indication of the level at the top, so that the level indicates zero scale; finally, the pole is fixed. For cylindrical poles, the pad can be removed, which is more convenient to use; when the level body is made of cast iron, the pad can be made of magnets, etc., so that it is more convenient to disassemble.

[0004] The above-mentioned related technologies have the following defects: currently in the construction process of wire poles, telescopic arms are mainly used to install wire poles into wire pole pits. After the wire pole clamps the wire pole clamps, the arm luffing cylinder of the telescopic arm is retracted to insert the wire pole into the wire pole pit. At this time, the wire pole will tilt, and it is necessary to adjust the wire pole luffing cylinder connected to the wire pole clamp to straighten the wire pole. After the wire pole is straightened, it will deviate from the wire pole pit again, and it is necessary to operate the telescopic cylinder of the telescopic arm to retract the telescopic arm, resulting in an extremely cumbersome operation process and the need for manual re-measurement and adjustment, which greatly affects the construction efficiency. Once the wire pole is tilted into the pit, it will cause the wire pole to break, affecting the construction quality. Summary of the invention

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses a vertical adjustment device for a power line pole vehicle. Figure 1 , Figure 2 and Figure 3 It includes a chassis 11, a telescopic arm 12 and a pole clamp 13. The chassis 11 is used to be installed on a movable frame. The telescopic arm 12 is provided with a pole luffing cylinder 14 for adjusting the pitch angle of the pole. The chassis 11 is provided with an arm luffing cylinder 15 for adjusting the pitch angle of the telescopic arm 12. The telescopic arm 12 is provided with a telescopic cylinder 16 for adjusting its length. The specific structure, connection method and control procedure of the above-mentioned components are conventional technologies and will not be repeated here.

[0021] It also includes an upper detection module 2 installed on the wire pole clamp 13 and a lower detection module 3 arranged on the peripheral side of the wire pole pit 6. Specifically, the upper detection module 2 is located on the non-moving part of the wire pole clamp 13, such as on its fixed seat.

[0022] The upper detection module 2 includes: The upper arc frame 21 is installed at the bottom end of the wire rod clamp 13, and is specifically configured to be coaxial with the wire rod clamped in the wire rod clamp 13; The central axis light emitter 22 is installed on the upper arc frame 21, and the strip light emitted downward is parallel to the central axis of the telescopic arm 12 and its extension line passes through the central axis of the wire pole to be installed in the wire pole fixture 13; and The side point light emitter 23 is installed at the free end of the upper arc frame 21 and emits light downward.

[0023] The lower detection module 3 includes: The lower arc frame 31 is adapted to the upper arc frame 21 and is located directly below it, and is used to be installed on the side of the wire rod pit 6; fixing holes 313 are opened at both ends of the lower arc frame 31, and anchor nails for fixing to the ground are passed through the fixing holes 313, which can stably fix the lower arc frame 31 after adjustment.

[0024] The central axis alignment strip 32 is arranged along the radial direction of the lower arc frame 31 and fixed to the upper end surface of the lower arc frame 31, and is used to cooperate with the strip light emitted by the central axis light emitter 22 to calibrate the position of the lower arc frame 31; and The side point light receiver 33 is arranged on the upper end surface of the lower arc frame 31 and is located directly below the side point light transmitter 23. It is in the shape of a long strip and its length direction is parallel to the central axis alignment strip 32. It is used to cooperate with the light emitted by the side point light transmitter 23 to monitor the pitch angle error of the pole to be installed.

[0025] Among them, in the specific configuration, the central axis light emitter 22 and the side point light emitter 23 can be infrared emitters or laser emitters. The difference is that the central axis light emitter 22 emits horizontal transverse light strips, and the side point light emitter 23 emits vertical light beams; the side point light receiver 33 is composed of an array of multiple photosensors, which can detect the position of the light spot on the light beam emitted by the side point light emitter 23, and the photosensor is only applicable to the specific light emitted by the aforementioned infrared emitter or laser emitter.

[0026] Therefore, when installing the power line pole, firstly, the pole to be installed is clamped by the pole clamp 13, and then moved to the pole pit 6 with the help of the chassis 11, and the posture of the telescopic arm 12 is adjusted so that its central axis is aligned with the central axis of the pole pit 6; then the lower arc frame 31 is placed on the side of the line pit, and the position of the lower arc frame 31 is calibrated by the strip light irradiated on the central axis alignment strip 32 by the central axis light emitter 22, specifically, it is ensured that the strip light is parallel to the central axis alignment strip 32 and is located at its center line, and then the lower arc frame 31 is fixed on the side of the pole pit 6, and the preparation work for the installation of the power line pole is completed.

[0027] Then, the posture of the pole to be installed is continuously adjusted by means of recovering the arm luffing cylinder 15, extending the pole luffing cylinder 14, recovering the telescopic cylinder 16, etc., so that it can be inserted into the pole pit 6 in a vertical state; in this process, if the posture of the pole changes, for example, when its lower end approaches the proximal end of the chassis 11, the landing point of the light emitted by the side point light transmitter 23 on the side point light receiver 33 is located on the side of the side point light receiver 33 close to the chassis 11, which can prompt the operator to adjust the pitch angle of the pole to be installed so that the landing point is restored to the midpoint position of the side point light receiver 33 to ensure the verticality of the pole to be installed; similarly, when the lower end of the pole to be installed approaches the distal end of the chassis 11, the pitch angle of the pole to be installed can be adjusted by means of the position of the above-mentioned landing point.

[0028] Among them, it should be clearly stated that since the strip light emitted by the installed central axis light emitter 22 is parallel to the central axis of the telescopic arm 12 and its extension line passes through the central axis of the pole to be installed or the central axis of the pole pit 6, during the installation of the pole, the posture deflection of the pole only occurs on the same plane where the above three lines are located, which can be called the pole pitch plane; combined with the cooperation of the side point light emitter 23 and the side point light receiver 33, the spatial posture change of the pole to be installed, that is, the change of its pitch angle, can be accurately obtained, which can greatly improve the installation and adjustment efficiency of the pole to be installed.

[0029] Specifically, refer to Figure 2 , Figure 3 and Figure 4 The side point light receiver 33 is connected to a detection controller, the midpoint of the side point light receiver 33 is set as the vertical midpoint, and the detection controller is configured as follows: If the vertical midpoint of the side point light receiver 33 receives the light emitted by the side point light transmitter 23, a qualified signal is output; If the side point light receiver 33 close to the end of the chassis 11 receives the light emitted by the side point light transmitter 23, it outputs a tilt control signal; If the side point light receiver 33 at the end away from the chassis 11 receives the light emitted by the side point light emitter 23 , a pitch control signal is output.

[0030] Moreover, the pole luffing cylinder 14, the arm luffing cylinder 15 and the telescopic cylinder 16 form an adjustment module and are commonly connected to an adjustment controller, the detection controller is electrically connected to the adjustment controller, and the adjustment controller is configured as follows: If the regulating controller receives a qualified signal, it controls the regulating module to operate so that the pole to be installed moves downward; If the adjustment controller receives the tilt control signal, it controls the adjustment module to work so that the lower end of the pole to be installed flips in a direction away from the chassis 11; If the adjustment controller receives the pitch control signal, it controls the adjustment module to work so that the lower end of the pole to be installed turns toward the direction close to the chassis 11 .

[0031] Furthermore, in order to further improve the degree of automatic control of the present application, alignment sensors 34 are installed at both ends of the central axis alignment bar 32. The alignment sensors 34 are the aforementioned photosensitive sensors that are only applicable to the specific light emitted by the infrared emitter or laser emitter selected by the aforementioned central axis light emitter 22. The two ends of the light strip emitted by the central axis light emitter 22 that falls on the central axis alignment bar 32 just correspond to two alignment sensors 34.

[0032] The two alignment sensors 34 are commonly connected to an alignment controller, the alignment controller has a higher priority than the detection controller, and only when the two alignment sensors 34 detect the strip light, the alignment controller controls the detection controller to operate.

[0033] Therefore, in the actual working process of the adjustment device of the present application, first, after the strip light emitted by the central axis light emitter 22 falls on the central axis alignment strip 32, if the two alignment sensors 34 sense the strip light at the same time, it means that at this time, on the one hand, the pole to be installed is on the predetermined pole pitch plane, and on the other hand, the lower arc frame 31 is installed in place, and the automatic installation of the power pole can be carried out. Then the detection controller works, and in the process of the adjustment module driving the pole to move downward, the detection controller can output a corresponding qualified signal, an elevation control signal or a pitch control signal according to the light signal received at different positions of the side point light receiver 33; after receiving the above signal, the adjustment controller can control the adjustment module to perform corresponding actions to move the pole to be installed downward, flip the lower end of the pole to be installed in a direction away from the chassis 11, or flip the lower end of the pole to be installed in a direction close to the chassis 11, until the detection controller outputs a qualified signal again; such a cycle can make the pole to be installed be installed in the pole pit 6 with a higher verticality.

[0034] In this process, as the pole clamp 13 moves down to the pole to be installed, the relative position of the central axis light emitter 22 and the central axis alignment strip 32 decreases, and the length of the strip light of the central axis light emitter 22 on the central axis alignment strip 32 is greater than the spacing between the two alignment sensors 34, that is, when the pole to be installed undergoes a small pitch change, the alignment controller will not trigger the action of controlling the detection controller to shut down, and the detection controller and the adjustment controller can still continue to work to ensure efficient work. However, once the pitch angle of the pole is deflected too much or the pole deviates from the pitch plane of the pole, the two alignment sensors 34 cannot detect the light emitted by the central axis light emitter 22 at the same time, and the detection controller and the adjustment controller must stop working, and the on-site operator must manually take over the operation, which can greatly improve the safety of the adjustment device of the present application when it is working on the basis of ensuring construction efficiency.

[0035] In addition, considering that when replacing poles with different outer diameters, especially when the outer diameter of the pole is larger, the probability of device jitter during installation of the pole is also greater, at this time, if the distance between the side point light emitter 23 and the central axis light emitter 22 is small, it will cause the sensitivity of the device to be too high, triggering frequent operation of the detection controller and the adjustment controller, which is not conducive to the efficient installation of the pole.

[0036] To this end, on the one hand, the upper arc frame 21 is configured to be rotatably mounted on the wire rod clamp 13, so that when installing wire rods with different outer diameters, the upper arc frame 21 can be horizontally rotated so that the distance between the side point light emitter 23 and the wire rod center axis in the wire rod clamp 13 and the distance between the center axis light emitter 22 and the wire rod center axis in the wire rod clamp 13 are the same.

[0037] On the other hand, referring to Figure 2 and Figure 3 An upper arc groove 211 and a lower arc groove 311 are respectively provided on the upper arc frame 21 and the lower arc frame 31. The side point light emitter 23 is slidably set in the upper arc groove 211 and is provided with an upper locking piece 212. The side point light receiver 33 is slidably set in the lower arc groove 311 and is provided with a lower locking piece 312. The upper locking piece 212 and the lower locking piece 312 are both common locking bolts, which can be locked after tightening the locking bolts; in addition, positioning scales are provided on the upper arc frame 21 and the lower arc frame 31 to mark the positions of the upper locking piece 212 and the lower locking piece 312 in the upper arc groove 211 and the lower arc groove 311 respectively after being locked, so as to locate the positions of the side point light emitter 23 and the side point light receiver 33.

[0038] The lower arc frame 31 is provided with a constant level mechanism for keeping the side point light receiver 33 and the central axis alignment bar 32 parallel.

[0039] Reference Figure 2 , Figure 3 and Figure 5 , Hengping institutions include: The slider 41 is slidably disposed in the lower arc groove 311, and the lower locking member 312 is used to lock the slider 41 in the lower arc groove 311; A rotating shaft 42 is rotatably mounted on the slider 41, and a middle portion of the side point light receiver 33 is fixedly connected to the rotating shaft 42; A locking assembly, used to lock the rotating shaft 42 on the slider 41; The telescopic rods 43 are provided with two, one end of which is hinged to the end of the central axis alignment bar 32 and the other end is hinged to the end of the side point light receiver 33, and the side point light receiver 33 is of the same length as the central axis alignment bar 32, so that the end of the central axis alignment bar 32, the side point light receiver 33 and the two telescopic rods 43 form a movable parallelogram, and the telescopic rods 43 are provided with a length scale for indicating the length thereof.

[0040] The locking assembly includes: The locking spring 51 is sleeved outside the rotating shaft 42, and one end of the locking spring 51 is pressed against the slider 41, and the other end of the locking spring 51 is pressed against the side point light receiver 33; The locking block 52 is fixedly connected to the lower end of the rotating shaft 42. The slider 41 is provided with a receiving groove 411 for the locking block 52 to slide. The rotating shaft 42 passes through the slider 41 from the receiving groove 411 and is fixedly connected to the side point light receiver 33. A damping rubber 53 is fixedly connected to one side of the locking block 52 close to the top wall of the receiving groove 411. The upper end surface of the damping rubber 53 is a frosted surface, which can further increase the friction resistance after the locking block 52 is lifted and tightened, and reduce the probability of the side point light receiver 33 rotating autonomously.

[0041] In this way, when the position adjustment of the upper arc frame 21 and the side point light emitter 23 is completed, the slider 41 is moved to the corresponding positioning scale beside the lower arc groove 311 according to the positioning scale of the side point light emitter 23 corresponding to the upper arc groove 211, and then the lower arc frame 31 is aligned and fixed. In the process of moving the slider 41 in the lower arc groove 311, the side point light receiver 33 can be pressed so that the rotating shaft 42 on it pushes the locking block 52 downward, so that the side point light receiver 33 can have a certain rotation ability on the slider 41. After the slider 41 moves into place, keep pressing the side point light receiver 33 and rotate it. By observing the length scale, the actual lengths of the two telescopic rods 43 are consistent. Then stop pressing, and the side point light receiver 33 moves upward under the deformation force of the locking spring 51, and the damping rubber on the locking block 52 is deformed. The glue 53 is pressed against the upper top wall of the accommodating groove 411, and the side point light receiver 33 can be fixed to a certain extent; at this time, since the two ends of the two telescopic rods 43 are respectively hinged to the two ends of the side point light receiver 33 and the central axis alignment strip 32, the four are in a standard parallelogram, which can ensure that the side point light receiver 33 and the central axis alignment strip 32 maintain a parallel posture. Therefore, when installing poles with different outer diameters, the poles to be installed on the pitch surface of the poles can be effectively monitored, and poles with different outer diameters can be installed efficiently and accurately.

[0042] The two ends of the telescopic rod 43 are movably hinged, and can be removed after the position adjustment of the side point light receiver 33 is completed to prevent interference with the entry of the wire pole into the wire pole pit 6.

[0043] The present application embodiment discloses a method for adjusting the verticality of a power line pole, based on the verticality adjustment device of a power line pole vehicle described above, referring to Figure 1 and Figure 4 , which comprises the following steps: S1. Clamp the pole to be installed by the pole clamp 13 and move the chassis 11 to the pole pit 6, adjust the telescopic arm 12 so that its central axis is aligned with the central axis of the pole pit 6; S2. The position of the lower arc frame 31 is calibrated by irradiating the strip light on the central axis alignment strip 32 through the central axis light emitter 22, and then the lower arc frame 31 is fixed to the side of the wire rod pit 6; S3. The control arm luffing cylinder 15, the telescopic cylinder 16 and the pole luffing cylinder 14 operate so that the pole slowly moves down in the pole pit 6; S4. During the process of moving the pole downward, the calibration of the central axis light transmitter 22 and the central axis alignment strip 32 is maintained, and the pitch angle error of the pole to be installed is monitored by using the position of the measuring point light transmitter irradiated on the side point light receiver 33, and the posture of the pole to be installed is controlled so that the light emitted by the measuring point light transmitter is always irradiated on the midpoint of the side point light receiver 33; S5. After the utility pole is installed and fixed, the chassis 11 is transferred to the next utility pole pit 6.

[0044] The implementation principle of the verticality adjustment device of a power line pole vehicle in the embodiment of the present application is as follows: When installing a power line pole, firstly, the pole to be installed is clamped by the pole clamp 13, and then the base 11 is used to move the pole to the pole pit 6, and the telescopic arm 12 is adjusted to align its central axis with the central axis of the pole pit 6; then the lower arc frame 31 is placed on the side around the line pit, and the position of the lower arc frame 31 is calibrated by the strip light irradiated on the central axis alignment strip 32 by the central axis light emitter 22, specifically, it is ensured that the strip light is parallel to the central axis alignment strip 32 and is located at its center line, and then the lower arc frame 31 is fixed on the side around the pole pit 6, and the preparation work for the installation of the power line pole is completed.

[0045] Then, the posture of the pole to be installed is continuously adjusted by means of recovering the arm luffing cylinder 15, extending the pole luffing cylinder 14, recovering the telescopic cylinder 16, etc., so that it can be inserted into the pole pit 6 in a vertical state; in this process, if the posture of the pole changes, for example, when its lower end approaches the proximal end of the chassis 11, the landing point of the light emitted by the side point light transmitter 23 on the side point light receiver 33 is located on the side of the side point light receiver 33 close to the chassis 11, which can prompt the operator to adjust the pitch angle of the pole to be installed so that the landing point is restored to the midpoint position of the side point light receiver 33 to ensure the verticality of the pole to be installed; similarly, when the lower end of the pole to be installed approaches the distal end of the chassis 11, the pitch angle of the pole to be installed can be adjusted by means of the position of the above-mentioned landing point.

[0046] Among them, since the strip light emitted by the installed central axis light emitter 22 is parallel to the central axis of the telescopic arm 12 and its extension line passes through the central axis of the pole to be installed or the central axis of the pole pit 6, during the installation of the pole, the posture deflection of the pole only occurs on the same plane where the above three lines are located, which is called the pole pitch plane; combined with the cooperation of the side point light emitter 23 and the side point light receiver 33, the spatial posture change of the pole to be installed, that is, the change of its pitch angle, can be accurately obtained, which can greatly improve the installation and adjustment efficiency of the pole to be installed.
