Embodiment 1

[0034] A portable cable manhole cover tool, such as figure 2 and Figure 5 As shown, it includes a pressing rod assembly 1, a steel wire rope 2 and a hook 3. The described pressing rod assembly 1 includes an upwardly open first rod 11, one end of the first rod 11 is hingedly connected to one end of the second rod 12, and the other end of the second rod 12 is The third bar 13 is hingedly installed. The compression bar assembly 1 can change the length of use, and adjust according to actual needs, so as to change the torque; the compression bar assembly 1 has a compact structure, does not occupy extra space, and is easy to carry and transport.

[0035] Such as Figure 1-Figure 4 As shown, the other end of the steel wire rope 2 is a bifurcated structure, each end is respectively equipped with a hook 3, and the lengths of the bifurcated sections are inconsistent. When in use, after the hook 3 is connected with the well cover, one side of the well cover is lifted up and then rem...

Embodiment 2

[0047] On the basis of Embodiment 1, the locking assembly 9 can also be another structure, such as Figure 7 As shown, that is, the locking assembly 9 includes a gear 91 and a bayonet pin 98. The gear 91 is installed on the bottom side of the middle part of the pressure rod assembly 1. The gear 91 is rotatably connected to the connecting sleeve 81 through the connecting shaft 82, and the gear 91 is fixedly connected to the connecting shaft 82. , the connecting shaft 82 is bearing-connected with the connecting sleeve 81; one side of the connecting sleeve 81 is provided with a round hole, and a bayonet pin 98 moving along it is arranged in the round hole, and the bayonet pin 98 is inserted between the teeth of the gear 91.

[0048] When in use, the user separates the bayonet pin 98 from the gear 91, and then rotates the pressing rod assembly 1. The rotation of the pressing rod assembly 1 drives the rotation of the gear 91, and the rotation of the gear 91 drives the rotation of th...

Abstract

The invention provides a portable tool for uncovering a cable manhole cover. The portable tool comprises a pressing rod assembly, a steel wire rope and a hook, wherein one end of the pressing rod assembly is provided with the steel wire rope through a hanging ring, a clamping block matched with the pressing rod assembly is arranged in the middle of the steel wire rope, and the other end of the steel wire rope is provided with a clamping hook; a bottom plate and a stand column are arranged on the lower side of the pressing rod assembly, a connecting sleeve matched with the pressing rod assemblyis arranged on the stand column, the pressing rod assembly is connected with the connecting sleeve through a connecting shaft, and a locking assembly for fixing the angle of the pressing rod assemblyis arranged in the connecting sleeve; the stand column is sleeved with a connecting rod moving along the stand column, and a clamping ring matched with the clamping hook is arranged on the connectingrod; and the stand column is provided with rotatable wheel rods, the lower ends of the wheel rods are provided with rollers capable of penetrating through the bottom plate, and the wheel rods are provided with sliding grooves matched with the two ends of the connecting rod. According to the portable tool for uncovering the cable manhole cover, the lever principle is utilized, and the cable manhole cover is effectively uncovered through the pressing rod and the stand column, so that the labor intensity and the number of people are reduced, personal injury is avoided, and the working efficiencyis improved; and the bottom plate is in contact with the ground during use, and the contact area is increased, so that the use stability is improved advantageously.

Description

technical field [0001] The invention belongs to the technical field of electric power survey equipment, in particular to a portable cable well cover tool. Background technique [0002] As the government's requirements for urban power planning are getting higher and higher, the cable conversion rate of power lines, especially urban power distribution lines, is also increasing. Cable manhole covers must be frequently uncovered and covered during the initial survey, intermediate construction, and later operation and maintenance of the cable line renovation project. [0003] At present, the commonly used tool for uncovering the cable well cover is a crowbar or a person directly manually uncovering the cover. Because the cable cover plate is heavy, the gap between the cover plates is small, and there are even three or four well covers in the cable well with many loops. The work efficiency is low and the labor intensity is high when the personnel bend over to remove the cover, an...
