Description

Technical Field

[0001] The utility model relates to the technical field of electricity safety protection, in particular to a safety electricity protection device. Background Art

[0002] The production process of an enterprise cannot be separated from automated machinery and equipment. When setting up automated machinery and equipment, they need to be combined with electrical equipment, that is, electromechanical installation. Electromechanical installation is a relatively large-scale project, including the installation of boilers, ventilation and air conditioning, refrigeration, electrical, instrumentation, motors, compressor units, and radio, film, and television broadcast control equipment. During the electromechanical installation process, a large number of mechanical and electrical equipment are required, so it is necessary to perform electromechanical installation on safety protection devices to ensure the safety of electricity use. Most of the protective devices used for electromechanical installation pass the wires over the ground and set up wire guards to protect the wires from damage by passing personnel and equipment; but the disadvantage of doing so is that although the wires are not damaged, when personnel and equipment touch the wire guards, they may accidentally trip, causing personal injury or equipment damage.

[0003] In the prior art, for example, the Chinese patent with the announcement number CN218498739U, entitled "An electrical safety protection device for electromechanical installation", discloses a technical solution that provides a protection platform, with support cylinders fixed at both ends of the protection platform, a lifting seat installed on the support cylinder, and a cable tie rod fixed on the upper end of the lifting seat. When in use, the lifting seat and the cable tie rod are lifted and lowered to drive the wires on the cable clamp to a suitable height, and the wires are lifted off the ground to prevent people and equipment from being tripped by the wires. However, when people and equipment pass under the wires, they may be blocked by the protection platform, thus posing a safety hazard. Utility Model Content

When the two sliders are close to each other, the slider drives the piston of the auxiliary hydraulic cylinder to slide, and presses the hydraulic oil in the hydraulic cavity of the auxiliary hydraulic cylinder into the sealing cavity, so as to drive the inner rod to extend upward, so as to extend the support rod and increase the height of passing through the gap.

[0013] Furthermore, two clamping mechanisms are symmetrically provided about the second direction and are distributed at both ends of the carrying plate; the clamping mechanism includes a center column, a clamping plate, and a trigger plate; the center column is vertically arranged and fixed on the carrying plate; multiple sliding columns are provided on both sides of the center column; multiple sliding columns are arranged at intervals along the second direction; the upper end of the sliding column is slidably mounted on the carrying plate through a sliding groove; a rhombus-distributed connecting rod is hinged between the center column and the adjacent sliding columns; through the rhombus-distributed connecting rod, when any sliding column is pushed to slide toward the center column, all sliding columns are made to slide toward the center column; multiple clamping plates are provided and distributed at the upper end of the carrying plate along the second direction; the clamping plate is fixed on the upper end of the sliding column; the middle clamping plate is fixed on the upper end of the center column; the opposite side walls of adjacent clamping plates are in an arc shape; the trigger plate is arranged along the second direction and is arranged at the lower end of the outermost sliding column; one end of the trigger plate close to the corresponding sliding column is fixed to the lower end of the sliding column, and the end away from the corresponding sliding column is in an arc shape and abuts against the inner rod side wall of the support rod.
