Description
Technical field
The present invention relates to a kind of equipment for coaster, specifically, relate to a kind of pulley sheave.
Background technology
At present, in order to ensure power supply quality, improve the inspection speed of transmission line, many employing coasters are hung on transmission line and carry out inspection and maintenance.Existing coaster many employings pulley, is hung on transmission line, and by surface personnel's pulling motion, but this pulley is in the process used, exist come off and the risk vibrated as: transmission line exists foreign matter and coaster can be caused to rock, even come off; The simultaneously stopping and moving ahead of coaster controls by ground staff mostly, and on coaster, staff freely cannot control the stopping of coaster as required, uses inconvenience.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, thus a kind of design science is provided, rational in infrastructure, strong adaptability, slip-off preventing are effective and the pulley sheave of good damping effect.
To achieve these goals, the technical solution adopted in the present invention is: a kind of pulley sheave, it comprises pulley base and pulley, wherein, described pulley base comprises top board, left side baffle plate, right-hand apron and spring shock (absorber) strut, the both sides of described top board are fixedly connected with one end of described spring shock (absorber) strut respectively, the other end of described spring shock (absorber) strut connects described left side baffle plate and described right-hand apron respectively, the wheel shaft two ends of described pulley are separately fixed on described left side baffle plate and described right-hand apron, described left side baffle plate and described right-hand apron are respectively arranged with corresponding chute, brake block is slidably equipped with in described chute.
Based on above-mentioned, it also comprises protective plate, is hinged bottom described protective plate one end and described right-hand apron, and the described protective plate other end is provided with snap close, is provided with the locking member supporting with described snap close bottom the baffle plate of described left side.
Based on above-mentioned, described left side baffle plate is or/and described right-hand apron is provided with braking spanner, and described braking spanner connects described brake block.
Based on above-mentioned, described top board is provided with link.
Based on above-mentioned, the rubbing surface of described pulley is arcs of recesses.
Hinge structure of the present invention has outstanding substantive distinguishing features and significant progress, specifically, the present invention is different from original pulley sheave, it comprises pulley base and pulley, wherein, described pulley base comprises top board, left side baffle plate, right-hand apron and spring shock (absorber) strut, during use, if transmission line exists foreign matter, spring shock structure can play the effect of damping and slip-off preventing; Brake block is set, facilitates the staff of coaster to stop coaster in time as required; It also comprises protective plate, mounts rear fastening protective plate, plays better slip-off preventing effect; It has design science, rational in infrastructure, strong adaptability, slip-off preventing are effective and the advantage of good damping effect.
