Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Examples

As shown in fig. 1, the hook special for the cable trench cover in the substation room comprises a bottom plate 1 which is in a cylindrical structure and is horizontally arranged, at least four support plates 2 which are horizontally arranged are arranged on the periphery of the bottom plate 1 at equal intervals, a hinge rod 3 hinged with the side wall of the bottom plate 1 is arranged right above each support plate 2, a supporting platform 4 parallel to the bottom plate 1 is arranged at the free end of each hinge rod 3, and the hook special for the cable trench cover is arranged through the supporting platform 4 in a natural state, so that the supporting platform 4 is parallel to the cable trench cover to be lifted as much as possible, the area of the hook when the hook is in contact with the cable trench cover is increased, and a powerful condition is provided for stably lifting the cable trench cover;

an adjusting plate 5 is arranged right above the bottom plate 1, the vertical center line of the adjusting plate 5 is coincident with the vertical center line of the bottom plate 1, at least one pinching block 10 is arranged at the top end of the adjusting plate 5, workers can conveniently gather the special hook through the pinching block 10, so that convenience is provided for the special hook to penetrate through a mounting hole in a cable trench cover plate, an upward extending pull rod 6 is vertically fixed at the center of the top end of the bottom plate 1, a rope hole 11 is arranged at the top end of the pull rod 6, the special hook is conveniently connected with a lifting rope through the rope hole 11, a through hole 7 for the free end of the pull rod 6 to penetrate through is arranged at the center of the adjusting plate 5, extending plates 8 which are parallel to the bottom plate 1 and are in one-to-one correspondence and alignment with the supporting plates 2 on the bottom plate are arranged at equal intervals on the circumference of the adjusting plate 5, a connecting rod 9 with one end hinged with, the free end of each connecting rod 9 is hinged with the hinge rod 3 on the corresponding side, the top end of the bottom plate 1 is fixed with a spring 12 wrapping the periphery of the pull rod 6, and the top end of the spring 12 is fixedly connected with the bottom end of the adjusting plate 5.

The specific application process of the hook special for the cover plate of the cable trench in the substation is as follows: when in use, a worker firstly fixes the pinching block 10 by hands and upwards pulls the adjusting plate 5 along the pull rod 6, so as to furl the special hook for the cable trench cover plate in a natural state, secondly, the furled special hook passes through the mounting hole on the cable trench cover plate, secondly, the pinching block 10 is released, so that the special hook returns to the natural state under the stretching of the spring 12, thereby the support table 4 on the special hook is positioned below the bottom end surface of the cable trench cover plate, secondly, the support table 4 in the natural state is contacted and supported with the bottom end surface of the cable trench cover plate by pulling the pull rod 6 through the lifted lifting rope, secondly, the cable trench cover plate contacted with the support table 4 downwards extrudes the support table 4 along with the continuous rising of the pull rod 6, thereby driving the hinged rod 3 to be unfolded by taking the vertical central line of the base 1 as the center of a circle, thereby driving the connecting rod 9 hinged with the upper end surface of the hinged rod 3 to be unfolded by taking the vertical central line of the adjusting plate 5 as the center of a circle, the adjusting plate 5 slides downwards on the pull rod 6 under the action of the connecting rod 9, so that the extending plate 8 performs downward translation work until the extending plate 8 is in close contact with the top end of the cable trench cover plate, and the extrusion work of the surface of the top end of the cable trench cover plate is realized while a certain point at the top ends of the unfolded hinge rods 3 supports the contacted cable trench cover plate, so that the stability in the hoisting process of the cable trench cover plate is ensured;

after the installation is finished, the lifting rope moves downwards to enable the pull rod 6 to move downwards under the action of the spring and the self gravity, so that the release work of the installed cable trench cover plate is realized, and then the special hook is taken out of the cable trench cover plate in a furled state, so that the use process of the special hook for the cable trench cover plate is completed.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
