Adopting the above-mentioned technical solution, the beneficial effects of the auxiliary device for opening a manhole cover provided by the embodiment of the present invention are as follows:

Because the auxiliary device for opening the manhole cover includes a frame, a mounting platform driven by the first power device is installed vertically on the frame, a turntable driven by the second power device is rotated on the installation platform, and dust is slidably installed on the top of the turntable. Loosening mechanism, the dust loosening mechanism is distributed on the periphery of the turntable and extends downward; the dust loosening mechanism is provided with a dust cleaning mechanism; there is also a manhole cover shaking mechanism driven by a third power device on the frame below the installation platform. Based on the above Structure, in actual use of the auxiliary device for opening a manhole cover, firstly, the auxiliary device for opening a manhole cover is moved to just above the manhole cover, and then, the first power device drives the installation platform down and loosens the dust loosening mechanism Located on the outer circumference of the manhole cover, after that, the second power device drives the turntable to rotate, and then drives the dust loosening mechanism to rotate. During the rotation process, the dust loosening around the manhole cover is completed. At the same time, the dust after transportation is cleaned by the dust cleaning mechanism. , the first power device drives the installation platform to return, and then the third power device drives the manhole cover shaking mechanism to shake the manhole cover, so that the outer circumference of the manhole cover is no longer closely matched with the ground or other structures, and the manhole cover can be easily opened at this time.

To sum up, compared with the traditional manual opening, the use of the auxiliary device for opening the manhole cover greatly reduces the labor intensity of the staff and the difficulty of opening the manhole cover, and it also takes less time, and the opening efficiency of the manhole cover is high, which ensures the power grid. The system can quickly carry out maintenance, maintenance and normal power supply; at the same time, it will not cause any damage to the manhole cover body, ensuring the service life of the manhole cover; in addition, the auxiliary device for opening the manhole cover is easy to operate, has good use effect, and is practical powerful.

Because the dust loosening mechanism includes a plurality of slide rails arranged on the upper surface of the turntable, each slide rail is slidably installed with a fan-shaped slider, one end of the fan-shaped slider close to the center point of the turntable is hinged with a buffer element, and the other end of the buffer element is hinged On the turntable; the other end of the fan-shaped slider is provided with a downwardly extending connecting block, a linear driving element is installed vertically on the connecting block, and a scraper is provided at the executive end of the linear driving element, so that when the periphery of the manhole cover is loosened, First, through the sliding of the fan-shaped slider along the slide rail, a plurality of scrapers are distributed on the periphery of the manhole cover. After that, the second power unit drives the turntable to rotate, so that the scraper loosens the dust packed around the manhole cover. The transition not only ensures the connection between the fan-shaped slider and the installation platform, but also lays a foundation for the loosening of dust around the inclined manhole cover.

Because the support column is fixed on the upper surface of the turntable, the support column is covered with a connecting sleeve, and the connecting sleeve and the support column are meshed together through the connecting teeth; the outer wall of the connecting sleeve is provided with a plurality of connecting lugs, and the buffer element is hinged to the connection Therefore, in use, according to the diameter of the manhole cover, by adjusting the engaging position of the connecting sleeve and the support column, the position of the connecting lug plate on the connecting sleeve relative to the fan-shaped slider can be adjusted.

The structure is simple, the shaking effect of the manhole cover is good, and the manhole cover is not damaged.

Since there is an avoidance groove on the shaking rod, the tie rod in the groove of the manhole cover is avoided by the avoidance groove, so that the shaking rod can be inserted into the groove of the manhole cover more deeply, and the contact area between the shaking rod and the manhole cover is increased, which is not only conducive to shaking The rod exerts force on the manhole cover, and the contact area between the shaking rod and the manhole cover is small, which causes damage to the manhole cover when force is applied.

Since there is a hanging shaft on the rocking rod located in the avoidance groove; the end of the rocking rod far from the installation platform is defined as the reference, and the distance between the hanging shaft and the reference is greater than the depth of the groove on the manhole cover, so that through this structure, the hanging The installation of the shaft not only does not affect the cooperation between the shaking rod and the manhole cover, but also facilitates the installation of the hanger for hoisting the manhole cover through the hanging shaft, and because there is a linear jacking element located on one side of the connecting block, the execution end of the linear jacking element faces the scraper. , and the execution end of the linear jacking element is provided with a walking wheel, so that when the manhole cover is moved, the other end of the hanger mounted on the hanging shaft is hung on the tie rod, and then the linear jacking element moves and makes the execution end extend The manhole cover is lifted out, and the manhole cover is lifted as a whole, and then the force is applied to the frame. The auxiliary device for opening the manhole cover can drive the movement of the manhole cover through the rolling of the walking wheels. The structure is simple, and there is no need for staff to manually Moving the manhole cover further reduces the labor intensity of the staff.

Since the bottom of the frame is provided with a plurality of universal rollers, the movement of the auxiliary device for opening the manhole cover is facilitated by the universal rollers; because the frame is also hinged with a pull rod, and the pull rod is provided with a handle, so that in use, The worker can realize the movement of the auxiliary device for opening the manhole cover by grasping the handle tightly by hand and applying a pulling force, which greatly improves the convenience of movement.
