Abstract

This utility model discloses a vertical control system for a utility pole erecting machine, belonging to the technical field of pole erecting machines, and solves the technical problem of low efficiency in verticality adjustment. The system includes a boom and a forearm. The forearm is equipped with a quick connector and a Y-direction adjusting cylinder that drives the quick connector to rotate up and down. The quick connector is connected to a pole gripper via an X-direction adjusting motor. The pole gripper is equipped with a gravity verticality detector. The controller detects the angular deviation of the utility pole in both the X and Y directions using the gravity verticality detector. It can simultaneously control the X and Y axis adjustments by linking the X-axis positive control proportional valve or the X-axis negative control proportional valve, and the Y-axis positive control proportional valve or the Y-axis negative control proportional valve, thereby improving construction efficiency and accuracy. When the angular deviation is large, the speed of the Y-direction adjusting cylinder and the X-direction adjusting motor can be further increased by using the Y-direction pilot handle and the X-direction handle button to further improve efficiency.

Description

Technical Field

[0001] This utility model relates to the field of pole erecting machine technology, and more specifically, it relates to a vertical control system for a utility pole erecting machine. Background Technology

[0002] Pole erecting machines are hoisting equipment used in the construction of power transmission and distribution lines. They are mainly used for pole erection operations and belong to the category of special construction machinery for power engineering.

[0003] For example, patent publication CN116122657A provides a pole erection control system and method for a power distribution network mechanized construction integrated machine. By setting an angle sensor in the pole erection mechanism, during the pole erection process, the boom, arm and pole erection mechanism are controlled to lift the pole and rotate it 90 degrees in the air. The angle sensor detects whether the pole is vertical. Once it is vertical, the arm and arm are controlled to lower the pole along the axis of the pole hole and install the pole into the pole hole.

[0004] Because manual operation during pole erection requires repeated measurements and adjustments to ensure the pole is vertical in the air, the process is time-consuming and inefficient in terms of verticality adjustment. Utility Model Content

[0023] Work process:

[0024] The pole erecting machine operates traditionally by clamping the utility pole, rotating it to the appropriate vertical angle, and placing it into a pre-drilled hole. During or after the pole has reached the bottom, pressing the one-button vertical installation adjustment on the controller automatically adjusts the pole to a vertical position. Specifically, the controller uses a gravity verticality detector to measure the angular deviation of the utility pole in both the X and Y directions. It can simultaneously control the X-axis positive or negative proportional valves, and the Y-axis positive or negative proportional valves in a coordinated manner to adjust both axes, keeping the angular deviation within the error range and improving construction efficiency and accuracy. When the angular deviation is large, the speed of the Y-axis adjusting cylinder can be further increased by controlling the shuttle valve via the Y-axis pilot handle, or by directly pressing the X-axis handle button, the controller can increase the current of the proportional valve to increase the speed of the X-axis adjusting motor, further improving efficiency.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
