Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1:

referring to fig. 1 to 3: a falling prevention device for power equipment comprises a mounting frame 1, at least two groups of rollers 2 and a falling prevention mechanism 3, wherein a guide cavity matched and sleeved on a power equipment slide rail is formed in the middle of the mounting frame 1, the at least two groups of rollers are sequentially arranged along the length direction of the guide cavity, each group of rollers comprises two rollers symmetrically arranged on two sides of the guide cavity, and each roller is mounted on the mounting frame and partially protrudes into the guide cavity; the anti-falling mechanism 3 is arranged corresponding to the lower roller 2 and comprises a tension component 4 and two limiting components 5, the two limiting components 5 correspond to the lower roller 22 one by one, each limiting component 5 comprises a limiting hook 51, a limiting spring 52 and a tension ring 53, one end of each limiting hook 51 is hinged to the connecting part 6 of the mounting frame 1, the other end of each limiting hook 51 forms a limiting surface, and a through hole 511 is formed in each limiting surface; at least one end of the limiting spring is connected with the limiting hook 51 and generates a limiting surface for driving the limiting hook 51 to abut against the elastic force of the lower roller 22, the tension ring 53 is arranged on the top surface of the connecting portion 6 of the mounting frame 1, the tension assembly 4 comprises a fixing frame 41, a roller 42 and a tension rope 43, the fixing frame 41 is mounted at the bottom of the electric power equipment, the roller 42 is rotatably mounted on the fixing frame 41, one end of the tension rope 43 is wound on the roller 42, the other end of the tension rope forms two tension ends, and the two tension ends are respectively connected into the through holes 511 of the limiting hook 51.

1 inside wall lower part of mounting bracket is equipped with connecting

portion

6, and 6 one end of this connecting portion is the stiff end other end for the hinged end (connecting

portion

6 and 1 fixed connection's of mounting bracket one end stiff end, the other end is the hinged end), sets firmly a tension ring 53 on the terminal surface of stiff end, and the protection rope passes the ring portion of tension ring 53, realizes the fixed to the protection rope, and it has first hinge hole to open on the hinged end, and the one end that spacing hook 51 and first hinge hole match is articulated portion, is equipped with the second hinge hole on the articulated portion, first hinge hole and second hinge hole position one-to-one, make spacing hook 51 can move about from top to bottom after the hinged end of spacing hook articulated portion and connecting portion articulates, is equipped with a through-hole 511 on spacing hook 51's the spacing face, and tension rope 43 rigid coupling is.

When limit hook only set up in one side of gyro wheel, probably because the gyro wheel became invalid the back mounting bracket extremely fast tenesmus in-process mounting bracket to a lopsidedness, can break away from the slide rail even, from safety consideration, limit hook sets up to two, is the symmetry setting, and the roller was kept away from to the pulling force rope both ends are connected respectively in two limit hook's through-hole, in order to prevent that the pulling force rope from droing, are equipped with a packing ring in through-hole and pulling force rope junction.

The utility model discloses a theory of operation does: roller and mounting bracket are two independent structures, during the installation, adorn the roller in the bottom of slide rail, then be connected the pulling force rope from the roller through-hole on pulling out and spacing hook, then be connected the protecting device on protecting rope and electric power maintainer body, upwards when electric power maintainer was ascending this moment, the mounting bracket upwards slides simultaneously, the pulling force rope was in taut state this moment, spacing hook kept away from the gyro wheel and contacted with the bottom of mounting bracket under the pulling force effect of pulling force rope, this in-process as long as the mounting bracket keeps rising, spacing hook can not contact with the gyro wheel promptly. After the gyro wheel became invalid, the mounting bracket can drop suddenly, and the pulling force rope is lax simultaneously spacing hook resets rapidly and blocks simultaneously between gyro wheel and slide rail because of the pulling force that loses the pulling force rope this moment to restriction gyro wheel lapse, the effective control mounting bracket is dropped, the personal safety of circuit maintenance personnel that has greatly limited.
