[0005] For the second type of cable trench cover and the third type of cable trench cover, on the one hand, because the construction personnel need to forcefully lift the cable trench cover, it takes a lot of physical strength for the construction personnel, which increases the labor force of the construction personnel. Labor intensity
On the other hand, because the construction workers need to remove the cable trench cover directly by hand, they are easy to be injured by the cable trench cover during the process of carrying the cable trench cover, which reduces the construction safety of the construction workers

Embodiment 1
[0052] Such as Figure 1-3 As shown, a cable trench cover prying device includes a moving frame 1, a lifting member 2, and a prying mechanism 3.
[0053] The mobile frame 1 includes a mobile plate 11 , a mobile leg 12 , and a mobile wheel 13 arranged in sequence from top to bottom. There are four moving legs 12, the upper ends of the four moving legs 12 are welded with the moving plate 11, and the lower ends of the four moving legs 12 are equipped with moving wheels 13.
[0054] In order to facilitate construction personnel to move the mobile frame 1, one end of the mobile plate 11 is welded with a mobile handle 111 .
[0055] Lifting part 2 adopts electric push rod. The upper end of the electric push rod is welded and fixed with the moving plate 11.
[0056] The prying mechanism 3 includes an inserting plate 31 , a rotating plate 32 and an adjusting plate 33 .
[0057] Two inserting plates 31 are arranged side by side, and a first connecting plate 311 is arranged between ...
Embodiment 2
[0083] Through the construction process of embodiment 1 "removing the cable trench cover 7 located on the cable trench", it can be seen that a kind of cable trench cover prying device in embodiment 1 can be moved back and forth between the cable trench and the open space. Take one cable trench cover plate 7, so when it is necessary to remove multiple cable trench cover plates 7, the user needs to push a kind of cable trench cover plate prying device in embodiment 1 to go back and forth between the cable trench and the open space Multiple trips. Thereby reducing the efficiency of removing a plurality of cable trench cover plates 7 from the cable trench.
[0084] In this regard, on the basis of Embodiment 1, this Embodiment 2 makes the following improvements:
[0085] Such as Figure 8-12 As shown, there are six moving legs 12, the upper ends of the six moving legs 12 are welded with the moving plate 11, and the lower ends of the six moving legs 12 are equipped with moving whe...

Abstract
The invention discloses a prying device for cable trench cover plates, and relates to the technical field of disassembling and assembling cable trench cover plates. It includes a moving frame, a lifting piece, and a prying mechanism. The prying mechanism includes a plug-in plate, a rotating plate, and an adjusting plate. The middle part of the plate is connected, one end of the rotating plate is hinged with the lower end of the adjusting plate, and the adjusting plate is slidingly connected with the inserting plate. When the lower end of the adjusting plate is flush with the lower end of the inserting plate, the rotating plate turns to the level supporting the cable trench cover state. The invention can reduce the labor intensity of the construction personnel and improve the construction safety of the construction personnel.
Description
technical field [0001] The invention relates to the technical field of disassembly and assembly of cable trench cover plates, in particular to a prying device for cable trench cover plates. Background technique [0002] When laying cables underground, it is necessary to bury cable trenches underground first, then lay cables in the cable trenches, and finally cover multiple cable trench covers side by side above the cable trenches. When construction workers overhaul and replace cables in the cable trench, they need to move a plurality of cable trench cover plates covering the cable trench to the open space, so that construction personnel can enter the cable trench for maintenance. [0003] Most of the cable trench covers are made of cement steel bars, and the weight usually reaches 40-50kg. The cable trench cover is mainly divided into three types according to the structure: the first type is a cable trench cover with a steel handle embedded; the second is a cable trench cov...
