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 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 related art, Chinese patent application number CN201410581948.0 proposes a reinforced concrete pole verticality measuring instrument and a method for calibrating a utility pole using the instrument. The instrument comprises a level body with a leveling plate. A removable pad is attached to the side of one end of the level body. The ratio of the horizontal thickness of the pad to the height of the level body is 1:75. Because the taper of a standard tapered pole is 1 / 75, the pad is attached to the side of the end of the level body. The level body is positioned with the pad facing upward, and the pad-bearing side is pressed against the side of the utility pole. The pole is then adjusted according to the leveling plate on top, until the level reaches zero. The level body is then moved 90 degrees around the circumference of the utility pole, and the level is adjusted according to the leveling plate on top, until the level reaches zero. Finally, the utility pole is secured. For cylindrical utility poles, the pad can be removed for increased convenience. For cast iron level bodies, the pad can be made of magnets, for example, for easier removal.

[0004] The above-mentioned related technologies have the following defects: At present, during the construction of wire poles, telescopic arms are mainly used to install wire poles into wire pole pits. After the wire pole clamp is clamped, the arm-length-changing 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 the wire pole-length-changing cylinder connected to the wire pole clamp needs to be adjusted to straighten the wire pole. After the wire pole is straightened, it will deviate from the wire pole pit again, and the telescopic cylinder of the telescopic arm needs to be operated 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

[0005] In order to improve the problem of low construction efficiency when installing power poles in pits using telescopic arms, the present application provides a verticality adjustment device for a power pole vehicle and an adjustment method thereof.

[0006] The first aspect of the present application provides a verticality adjustment device for a power line pole vehicle, which adopts the following technical solution:

[0023] If the adjustment controller receives the pitch control signal, it controls the adjustment module to operate so that the lower end of the to-be-installed pole flips toward the direction close to the chassis.

[0024] Furthermore, alignment sensors are installed at both ends of the central axis alignment strip, and the two ends of the light beam emitted by the central axis light emitter that falls on the central axis alignment strip just correspond to two of the alignment sensors;

[0025] The two alignment sensors are commonly connected to an alignment controller. The alignment controller has a higher priority than the detection controller, and only when both the alignment sensors detect the strip light, the alignment controller controls the detection controller to operate.

[0026] Furthermore, an upper arc groove and a lower arc groove are respectively provided on the upper arc frame and the lower arc frame, the side point light emitter is slidably set in the upper arc groove and is provided with an upper locking piece, the side point light receiver is slidably set in the lower arc groove and is provided with a lower locking piece, and the lower arc frame is provided with a constant level mechanism for keeping the side point light receiver parallel to the central axis alignment bar.

[0036] Furthermore, both ends of the lower arc-shaped frame are provided with fixing holes, and anchor nails for fixing to the ground are passed through the fixing holes.

[0037] The second aspect of the present application provides a method for adjusting the verticality of a power line pole using the following technical solution:

[0038] A method for adjusting the verticality of a power line pole, based on the verticality adjustment device of a power line pole vehicle, comprises the following steps:

[0039] S1. Clamp the pole to be installed by the pole clamp and move the chassis to the pole pit, adjust the telescopic arm so that its central axis is aligned with the central axis of the pole pit;

[0040] S2. The position of the lower arc frame is calibrated by irradiating the strip light on the central axis alignment strip through the central axis light emitter, and then the lower arc frame is fixed to the side of the wire rod pit;

[0041] S3. Control the arm luffing cylinder, the telescopic cylinder and the pole luffing cylinder operation so that the pole slowly moves down in the pole pit;

[0042] S4. During the process of lowering the utility pole, the alignment between the central axis light transmitter and the central axis alignment bar is maintained. Simultaneously, the pitch angle error of the utility pole to be installed is monitored by using the position of the lateral light transmitter on the lateral light receiver. The posture of the utility pole to be installed is controlled so that the light emitted by the lateral light transmitter always illuminates the midpoint of the lateral light receiver.

[0043] S5. After the utility pole is installed and fixed, the chassis is transferred to the next utility pole pit.

[0044] In summary, the beneficial technical effects of this application are:

[0045] 1. By aligning the strip light emitted by the central axis light transmitter parallel to the central axis of the telescopic arm, with its extension passing through the central axis of the pole to be installed, or the central axis of the pole pit, during the installation process, the pole's posture deflection only occurs on the same plane as the three lines, known as the pole pitch plane. Combined with the coordination of the side-point light transmitter and the side-point light receiver, the spatial posture change of the pole to be installed, that is, the change in its pitch angle, can be accurately determined, greatly improving the installation and adjustment efficiency of the pole to be installed.

[0046] 2. The alignment controller determines whether the utility pole to be installed is on the predetermined utility pole pitch plane, and controls the working state of the detection controller. Thus, when the adjustment module drives the utility pole downward, the detection controller can output a corresponding qualified signal, an elevation control signal, or a pitch control signal according to the light signals received by the light receivers at different positions of the side points. After receiving the above signals, the adjustment controller can control the adjustment module to perform corresponding actions to move the utility pole to be installed downward, flip the lower end of the utility pole to be installed away from the chassis, or flip the lower end of the utility pole to be installed toward the chassis, until the detection controller outputs a qualified signal again. This cycle allows the utility pole to be installed in the utility pole pit with a high degree of verticality.

[0047] 3. By hingedly connecting the ends of the two telescopic rods to the ends of the side point light receivers and the center axis alignment bar, the four are arranged in a standard parallelogram. This ensures that when adapting to poles of different outer diameters, the side point light receivers and the center axis alignment bar can remain parallel. Therefore, when installing poles of different outer diameters, the poles to be installed on the pitch plane can be effectively monitored, and poles of different outer diameters can be installed efficiently and accurately.

[0060] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0061] The embodiment of the present application 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.

[0062] It also includes an upper detection module 2 installed on the wire rod clamp 13 and a lower detection module 3 arranged on the side of the wire rod pit 6. Specifically, the upper detection module 2 is located on the non-moving part of the wire rod clamp 13, such as on its fixed seat.

[0063] Upper detection module 2 includes:

[0064] 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;

[0065] The central axis light emitter 22 is mounted on the upper arc frame 21, and the strip light it emits downward is parallel to the central axis of the telescopic arm 12, and its extension line passes through the central axis of the wire rod to be installed in the wire rod fixture 13; and

[0066] The side point light emitter 23 is mounted on the free end of the upper arc frame 21 and emits light downward.

[0067] The lower detection module 3 includes:

[0068] 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.

[0069] A central axis alignment strip 32 is provided radially along 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

[0070] 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 emitter 23. It is long 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 emitter 23 to monitor the pitch angle error of the pole to be installed.

[0071] 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.

[0072] Therefore, when installing the power pole, first clamp the pole to be installed with the pole clamp 13, then move it to the pole pit 6 with the help of the chassis 11, adjust the posture of the telescopic arm 12 so that its central axis is aligned with the central axis of the pole pit 6; then place the lower arc frame 31 on the side of the wire pit, and calibrate the position of the lower arc frame 31 by irradiating the strip light on the central axis alignment strip 32 by the central axis light emitter 22, specifically, ensure that the strip light is parallel to the central axis alignment strip 32 and is located at its center line, and then fix the lower arc frame 31 on the side of the wire pit 6, thus completing the preparation work for the installation of the power pole.

[0073] Then, the posture of the utility pole to be installed is continuously adjusted by retracting the arm luffing cylinder 15, extending the utility pole luffing cylinder 14, and retracting the telescopic cylinder 16, so that it can be inserted into the utility pole pit 6 in a vertical state. During this process, if the posture of the utility pole changes, for example, when its lower end approaches the proximal end of the chassis 11, the point where the light emitted by the side point light emitter 23 falls 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 utility pole to be installed so that the landing point is restored to the midpoint of the side point light receiver 33 to ensure the verticality of the utility pole to be installed. Similarly, when the lower end of the utility pole to be installed approaches the distal end of the chassis 11, the pitch angle of the utility pole to be installed can be adjusted by means of the position of the above-mentioned landing point.

[0074] Among them, it needs to 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, therefore, during the installation process 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.

[0075] 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:

[0076] If the vertical midpoint of the side point light receiver 33 receives the light emitted by the side point light emitter 23, a qualified signal is output;

[0077] If the side point light receiver 33 close to the end of the chassis 11 receives the light emitted by the side point light emitter 23, it outputs the tilt control signal;

[0078] 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 , it outputs a pitch control signal.

[0079] Furthermore, the rod luffing cylinder 14, the arm luffing cylinder 15 and the telescopic cylinder 16 constitute 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:

[0080] If the adjustment controller receives a qualified signal, it controls the adjustment module to operate so that the pole to be installed moves downward;

[0081] 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 is flipped away from the chassis 11;

[0082] If the adjustment controller receives the pitch control signal, it controls the adjustment module to operate so that the lower end of the to-be-installed pole flips toward the direction close to the chassis 11 .

[0083] In addition, 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.

[0084] 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 both the two alignment sensors 34 detect the strip light, the alignment controller controls the detection controller to operate.

[0085] Therefore, during the actual operation of the adjustment device of the present application, first, the strip of light emitted by the central axis light emitter 22 falls on the central axis alignment strip 32. If the two alignment sensors 34 simultaneously sense the strip of light, it indicates that the power pole to be installed is in the predetermined pitch plane and the lower arc frame 31 is installed in place, allowing the automated installation of the power pole to proceed. The detection controller then operates. As the adjustment module drives the pole downward, the detection controller can output a corresponding pass signal, an elevation control signal, or a pitch control signal based on the light signals received at different positions of the side point light receivers 33. After receiving these signals, the adjustment controller can control the adjustment module to perform corresponding actions, causing the pole to move downward, tilt the lower end of the pole to be installed away from the chassis 11, or tilt the lower end of the pole to be installed toward the chassis 11, until the detection controller outputs a pass signal again. This cycle allows the pole to be installed in the pole pit 6 with a high degree of verticality.

[0086] During 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 distance 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 operation. However, once the pitch angle of the pole deflects 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. On the basis of ensuring construction efficiency, it can greatly improve the safety of the adjustment device of this application during operation.

[0087] In addition, considering that when replacing utility poles with different outer diameters, especially when the outer diameter of the utility pole is larger, the probability of device jitter during installation of the utility 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 operations of the detection controller and the adjustment controller, which is not conducive to the efficient installation of the utility pole.

[0088] To this end, on the one hand, the upper arc frame 21 is set 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.

[0089] On the other hand, refer to Figure 2 and Figure 3 The upper arc frame 21 and the lower arc frame 31 are respectively provided with an upper arc groove 211 and a lower arc groove 311. 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 they are locked, so as to locate the positions of the side point light emitter 23 and the side point light receiver 33.

[0090] The lower arc frame 31 is provided with a constant leveling mechanism for keeping the side point light receiver 33 and the central axis alignment bar 32 parallel.

[0091] Reference Figure 2 、 Figure 3 and Figure 5 , Hengping institutions include:

[0092] The slider 41 is slidably disposed in the lower arc-shaped groove 311 , and the lower locking member 312 is used to lock the slider 41 in the lower arc-shaped groove 311 ;

[0093] 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;

[0094] A locking assembly, used to lock the rotating shaft 42 on the slider 41;

[0095] The telescopic rods 43 are provided with two ends, 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. 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. The telescopic rods 43 are provided with a length scale for indicating their length.

[0096] The locking assembly includes:

[0097] The locking spring 51 is sleeved on the outside of the rotating shaft 42, with one end pressed against the slider 41 and the other end pressed against the side point light receiver 33;

[0098] The locking block 52 is fixed to the lower end of the rotating shaft 42. The slider 41 defines a receiving slot 411 for the locking block 52 to slide in. The rotating shaft 42 passes through the receiving slot 411 and then is fixed to the side-point light receiver 33. A damping rubber 53 is fixed to the side of the locking block 52 near the top wall of the receiving slot 411. The upper end surface of the damping rubber 53 is frosted to further increase the frictional resistance when the locking block 52 is lifted and tightened, thereby reducing the possibility of the side-point light receiver 33 rotating on its own.

[0099] In this way, after 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 next to 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, the side point light receiver 33 is kept pressed and rotated. By observing the length scale, the actual lengths of the two telescopic rods 43 are made consistent. Then, the pressing is stopped. 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 tightly against the upper top wall of the accommodating groove 411, which can fix the side point light receiver 33 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 pole can be effectively monitored, and poles with different outer diameters can be installed efficiently and accurately.

[0100] 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 rod into the wire rod pit 6.

[0101] The present application embodiment discloses a method for adjusting the verticality of a power line pole, based on the verticality adjustment device of the power line pole vehicle mentioned above, referring to Figure 1 and Figure 4 , which includes the following steps:

[0102] 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;

[0103] S2. The position of the lower arc frame 31 is calibrated by the central axis light emitter 22 irradiating the strip light on the central axis alignment strip 32, and then the lower arc frame 31 is fixed to the side of the wire rod pit 6 weeks;

[0104] S3. The control arm luffing cylinder 15, the telescopic cylinder 16 and the pole luffing cylinder 14 operate so that the pole slowly moves downward in the pole pit 6;

[0105] S4. During the process of lowering the pole, the alignment between the central axis light emitter 22 and the central axis alignment bar 32 is maintained. At the same time, the pitch angle error of the pole to be installed is monitored by using the position of the side point light emitter 23 on the side point light receiver 33. The posture of the pole to be installed is controlled so that the light emitted by the side point light emitter 23 always illuminates the midpoint of the side point light receiver 33.

[0106] S5. After the utility pole is installed and fixed, the chassis 11 is transferred to the next utility pole pit 6.

[0107] The implementation principle of the verticality adjustment device of a power line pole vehicle in the embodiment of the present application is as follows:

[0108] When installing a power pole, first, the pole to be installed is clamped by the pole clamp 13, and then the base 11 is used to move it to the pole pit 6, 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 pole 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, thus completing the preparations for the installation of the power pole.

[0109] Then, the posture of the utility pole to be installed is continuously adjusted by retracting the arm luffing cylinder 15, extending the utility pole luffing cylinder 14, and retracting the telescopic cylinder 16, so that it can be inserted into the utility pole pit 6 in a vertical state. During this process, if the posture of the utility pole changes, for example, when its lower end approaches the proximal end of the chassis 11, the point where the light emitted by the side point light emitter 23 falls 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 utility pole to be installed so that the landing point is restored to the midpoint of the side point light receiver 33 to ensure the verticality of the utility pole to be installed. Similarly, when the lower end of the utility pole to be installed approaches the distal end of the chassis 11, the pitch angle of the utility pole to be installed can be adjusted by means of the position of the above-mentioned landing point.

[0110] 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 process 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 between 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.
