Cable trench cover plate opening tool

Abstract

The invention discloses a cable trench cover plate opening tool, and relates to the field of power distribution operation and maintenance. The cable trench cover plate opening tool is characterized inthat a support mechanism is fixed to a moving mechanism; a suspension mechanism is fixed to the support mechanism; an adjusting mechanism is mounted on the suspension mechanism; a lever mechanism issuspended at the tail end of the suspension mechanism; and a lifting mechanism is clamped on the lever mechanism. According to the cable trench cover plate opening tool disclosed by the invention, a device is moved through the moving mechanism, so that labor force is saved; the cable trench cover plate opening tool can enter a narrow area, and has high universality; the height of a connector and the height of a hook can be adjusted in a suspension manner through the adjusting mechanism, so that the cable trench cover plate opening tool has a plurality of working modes, and is easy to operate,rapid in adjustment, and firm in fixation; the lever mechanism can be suspended through the suspension mechanism, lifting of a cover plate is more labor-saving according to the lever principle, and workers can set different lever ratios as required through four or more fixing rings, so that the cable trench cover plate opening tool has high adaptability, and can be used for lifting cable trench cover plates of various weights.

Description

technical field [0001] The invention relates to the field of power distribution operation and maintenance, in particular to a cable trench cover opening tool. Background technique [0002] Power distribution operation and maintenance personnel need to open the cable trench cover when performing engineering acceptance, troubleshooting, and upgrade assembly operations on underground cables. At present, most cable trench covers are made of reinforced concrete, which is heavy, and the old ones have lifting holes. The cover plate has been eliminated because it cannot prevent urban waste from falling into the cable trench. Most of the widely used cable trench cover plates do not have lifting holes. Tools, the old-fashioned opening tool with hooks cannot be fixed on the new cover. When it is necessary to open a large number of covers in a large range, the work efficiency is very low, the operation is complicated, and it takes a lot of manpower and material resources, and it is impo...

[0002] Power distribution operation and maintenance personnel need to open the cable trench cover when performing engineering acceptance, troubleshooting, and upgrade assembly operations on underground cables. At present, most cable trench covers are made of reinforced concrete, which is heavy, and the old ones have lifting holes. The cover plate has been eliminated because it cannot prevent urban waste from falling into the cable trench. Most of the widely used cable trench cover plates do not have lifting holes. Tools, the old-fashioned opening tool with hooks cannot be fixed on the new cover. When it is necessary to open a large number of covers in a large range, the work efficiency is very low, the operation is complicated, and it takes a lot of manpower and material resources, and it is impossible to enter narrow areas. low work efficiency
