Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

The utility model provides a line overhauls with climbing pole cat ladder, as shown in figure 1, including the mobile jib body 1, the mobile jib body 1 top is provided with couple 2, and couple 2 is the goat's horn shape, including crossbeam 2b and a pair of coupler body 2c, and coupler body 2c is the arc and sets up at crossbeam 2b both ends, can dismantle fixedly through fasteners such as screws between crossbeam 2b and the mobile jib body 1. So set up, the cat ladder is more at the last strong point of cable, and the triangle-shaped structure is more stable. In order to ensure the structural strength of the two, a reinforcing rib 2a is further arranged below the cross beam 2b, and the head of the main rod body 1 is clamped by the reinforcing rib 2 a.

As can be seen from fig. 1 and 2, the main lever 1 has accommodating grooves 1a on both sides thereof, the accommodating grooves 1a are distributed in a staggered manner, the pedal lever 3 is mounted on the accommodating groove 1a, the lower end of the pedal lever 3 is rotatably connected to the accommodating groove 1a through the hinge shaft 7, the inner side of the upper end of the pedal lever 3 is provided with a guide surface 3a, the outer side thereof is provided with a locking groove 3b, and the locking groove 3b is engaged with the locking lever 4 when being received in the accommodating groove 1 a. Vertical the sliding of gag lever post 4 is installed on the mobile jib body 1, and the spout on the mobile jib body 1 just in time is located holding tank 1a top, and this spout side direction opening to make things convenient for horizontal control handle 4b to stretch out on the gag lever post 4, with control

gag lever post

4, 4 afterbody of gag lever post set up spring 5, and spring 5 is with gag lever post 4 propelling movement downwards. The head of the limiting rod 4 is abutted against the clamping groove 3b in a normal state, and the pedal rod 3 is limited in the containing groove 1 a.

Referring to fig. 2 in particular, the outward rotation of the foot bar 3 may be achieved by providing a torsion spring 6 on the hinge shaft 7, one end of the torsion spring 6 abutting against the foot bar 3 and the other end thereof being supported at the side wall of the receiving groove 1a, thereby applying an outward rotation elastic force to the foot bar 3. In order to ensure that the pedal lever 3 can be better supported when rotated to the horizontal position, an auxiliary support block 8 may be additionally provided near the notch of the receiving groove 1 a. In addition to the torsion spring 6, the pedal 3 can be ejected outwards by magnetic force, for example, a magnet is mounted on the pedal 3, a magnet is mounted on the bottom of the accommodating groove 1a, and the two magnets repel each other when the pedal 3 is in the storage state.

When the pedal rod 3 needs to be unfolded, the operating handle 4b is pulled by a hand, so that the limiting rod 4 overcomes the acting force of the spring 5 to contract inwards, and the pedal rod 3 rotates outwards under the action of the pop-up assembly after being not limited. The operating handles 4b can adopt a linkage mode, namely, connecting rods are arranged in the main rod body 1 to connect all the operating handles 4b together, so that the operation is more convenient. When pedal lever 3 is withdrawed to needs, manual rotation pedal lever 3, the cooperation of inclined plane 4a on guide face 3a on the pedal lever 3 and the gag lever post 4, with gag lever post 4 inwards press, when rotating to draw-in groove 3b opposite with gag lever post 4, then draw-in groove 3b is gone into to gag lever post 4 under the effect of spring 5 to the accomodation of pedal lever 3 has been realized.

Specifically referring to fig. 3, for the sake of safety, the main rod body 1 may be hinged with a clamping strip 9 below the hook 2, the clamping strip 9 is hinged in the same manner, the main rod body 1 is provided with an installation groove 1b on the back surface, the clamping strip 9 is hinged at the bottom of the installation groove 1b, a clamping block 10 is arranged at the notch of the installation groove 1b, and the inner side of the clamping block 10 is an inclined surface. When the cat ladder is put in an inclined mode, the cable is pulled into the hook 2 in the clamping strip 9, the clamping strip 9 rotates downwards under the action of self gravity and finally collides with the clamping block 10 to form the state shown in the figure 3, and therefore the cable is embraced in the hook 2 and the clamping strip 9. The clamping strip 9 is a sectional structure, the upper section and the lower section are in threaded connection, when the ladder is required to be removed from the cable, the upper section is removed, and the cable can be pulled out from the opening between the lower end and the hook 2.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
