[0025] Embodiment 1:

[0026] When construction workers turn over the cable manhole cover, they usually insert a pry bar into the small pit around the manhole cover, use the lever principle to pry the manhole cover open a gap, and then use manpower to pad the manhole cover along the pried gap, and then pull up the manhole cover. Because the manhole cover is too heavy, workers are easily injured; some cable manhole covers have been deformed due to long years of use, and the gap in contact with the ground is small, so workers cannot use pry bars to open the manhole cover normally.

[0027] In response to the above problems, Figure 1 As shown, this embodiment provides an auxiliary device for opening a cable manhole cover, including a supporting mechanism 1, a sleeve 2, a bearing 3, an operating mechanism 4 and a hook 5.

[0029] The support mechanism 1 includes a support rod 101, the operating mechanism 4 is arranged in the middle position of the support rod 101, and bases 102 are respectively arranged at both ends of the support rod 101. By symmetrically arranging the bases 102 at both ends of the support mechanism 1, the overall force of the device is decomposed to the two ends of the support mechanism, thereby improving the stability of the cable well cover auxiliary device.

[0030] In this embodiment, the base 102 is a truncated cone, which is arranged on the support rod 101 by welding or bolt connection. The base 102 is a truncated cone, which increases the force-bearing area and further improves the stability.

[0031] In some embodiments, the base 102 is provided with a plurality of connection holes, and the base 102 is fixed to the ground or other work platform by means of bolts or screws. For example, the base 102 is fixed to a work vehicle by means of bolts or screws, so as to facilitate the overall movement of the device to the working position, and the device can work directly on the work vehicle.
