Abstract
A lifting rotating type installing bracket of hoister current-collector relates to a mobile power supply device of a hoister. An installing bracket of a current-collector in the prior art has a single path of movement, when a hoister which is equipped with a pressure-type current-collector is examined and repaired, the hoister is not only needed to be driven to a plant examination and repair zone, but also the power supply of the plant needs to be cut off, and the installation and maintenance of the current-collector are not very convenient. The lifting rotating type installing bracket of hoister current-collector combines a rotary type installing bracket with a single path of movement with a lifting type installing bracket to form an installing bracket which can be lifted and rotated. The lifting rotating type installing bracket of hoister current-collector is characterized in that two lifting doors are respectively fixed with two rotating doors (namely the rotating doors are the support door frames of lifting doors) together through a fixing device which can regulate strokes, and the current-collector is mounted on the lifting doors. The lifting rotating type installing bracket of hoister current-collector not only can be used to install a pressure-type current-collector, but also can be used to install a lateral-pressure type current-collector, and solves the shortcomings that the prior art is inconvenient to install and maintain current-collectors.

Summary of the invention
The purpose of this utility model is exactly in order to overcome the shortcoming of prior art, a kind of up-down rotary type mounting bracket of hoisting crane current colector is provided, not only can be used for the installation of roof pressing type current colector, also can be used for the installation of side compression type current colector, solve the shortcoming of prior art current colector installation and maintenance inconvenience.
The utility model is achieved through the following technical solutions its purpose:
A kind of up-down rotary type mounting bracket of hoisting crane current colector combines the rotary mounting bracket and the lifting mode mounting bracket of the single movement track of prior art, forms the also rotatable mounting bracket of liftable.Concrete structure is as follows:
A kind of up-down rotary type mounting bracket of hoisting crane current colector, comprise: rotary support and lifting mode support that current colector is installed, described rotary support: the revolving door that its revolving door supports channel-section steel and is positioned at the revolving door both sides supports angle steel and is fixed on the inspection platform of hoisting crane, one side of two fan revolving doors is hinged with two revolving doors support angle steel respectively by hinge, and the opposite sides of two fan revolving doors support channel-section steel with revolving door respectively by bearing pin and peg graft; Described lifting mode support: its two fans overhead door is connected with the supporter of overhead door respectively by the anchor fitting that has adjustment travel, the bottom of overhead door is connected with jacking system, it is characterized in that: the supporter of described overhead door is a revolving door, that is: two fan overhead doors are fixed together by (the support doorframe that revolving door is overhead door) with two fan revolving doors respectively by the anchor fitting that has adjustment travel, and current colector is installed on the overhead door.
The described anchor fitting that has adjustment travel is made up of two locating pieces and connecting screw rod, and No. 1 locating piece and overhead door are fixed, the frame fixation of No. 2 locating pieces and revolving door, and No. 1 locating piece is connected with screw rod with No. 2 locating pieces.
The described anchor fitting that has adjustment travel has 4 at least.
Described jacking system is a kind of manual type worm-and-wheel gear.
The utility model compared with prior art, during the maintenance current colector, shake the handle rising overhead door on the jacking system, make current colector and factory building slip break away from (current colector outage, hoisting crane is in off-position), after rotating revolving door to 80～90 degree, just can on the inspection platform of hoisting crane, overhaul current colector.Adopt this device, just not needing to travel to the maintenance zone for the hoisting crane that the roof pressing type current colector is installed can be under the situation that factory building does not cut off the power supply, and current colector is safeguarded and changed, and has shortened the maintenance time of hoisting crane, has improved work efficiency.This structure operation is simple, and is safe and reliable.
