Abstract
The utility model discloses a pantogrpah for crane, which aims at providing a pantogrpah which can make the contact between a brush and a track be good, the performance is durable, the structure is strong, and the operation is flexible, the margin is large, and can be applicable for being used in continuous track. The utility model comprises a permanent seat, an upper connecting rod, a lower connecting rod and a brush; the permanent seat is provided with a shaft which is vertical to the permanent seat; the shaft is covered with a rotating shaft block, the rotating shaft block is hinge connected with the upper connecting rod and lower connecting rod; the other end of the upper connecting rod and lower connecting rod is hinge connected with a mandril block; an extension spring is arranged between the upper connecting rod and the lower connecting rod; one end of the extension spring is fixed at an upper suspension loop of the upper connecting rod, and the other end is fixed at an lower suspension loop of the lower connecting rod; a mandril is inserted into the mandril block, and the mandril is connected with the brush, the interface between the top and the brush is in an arc shape.
Description
Technical field
The utility model relates to a kind of Electricity collecting frame, particularly a kind of crane Electricity collecting frame.
Background technology
Flourish along with industry, a lot of factory floors, warehouse all transmit material by crane system, in the hope of increasing work efficiency.In order to make crane system safe and reliable in use, crane system can adopt the electric rail of continuous type as the transmission of electricity track, the brush of and electric rail moving contact fixing by Electricity collecting frame, prevent that brush breaks away from electric rail, realize electrically connecting of electric rail and mobile electrical devices, and Electricity collecting frame alerting ability in the past is relatively poor, and design is compact inadequately.In addition, its nargin is little, and is not accurate enough if electric rail has injustice or Electricity collecting frame to install slightly, the brush on the Electricity collecting frame just may with electric rail bad contact, it is unreliable to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of brush that can make to contact well with electric rail, and is durable, structure is strong, and action flexibly, nargin is big, and is suitable for the Electricity collecting frame that uses on the continuous type electricity rail.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Electricity collecting frame, comprise permanent seat, boxed rod, lower link and brush, the axle perpendicular with it arranged on described permanent seat, be with shaft seat on the described axle, described shaft seat hinge joint boxed rod and lower link, the other end hinge joint tip-lever support of described boxed rod and lower link, be connected with extension spring between boxed rod and the lower link, described extension spring one end is fixed on the last hangers of boxed rod, the other end is fixed on the following hangers of lower link, be inserted with push rod on the described tip-lever support, described push rod connects brush, and the contact surface of its top and brush is circular-arc.
The beneficial effects of the utility model are: boxed rod and lower link hinge joint can be rotated around anchor shaft on shaft seat, and action is flexible, nargin is big; Boxed rod cooperates extension spring with lower link, brush is close on the electric rail level with suitable pressure steadily slides, electrically contact good and structure strong; The opposite face of boxed rod and lower link is respectively equipped with projection, and by the restriction of projection, the opposite face of two connecting rods can directly be close to, and the upward force that spring is provided remains on certain value; Spring is hidden in the connecting rod, can avoid in stroke and the contacting of foreign object, and prevents the generation of short circuit accident; The boss of push rod tail end matches with tip-lever support circular hole inner end surface, and push rod and brush fixed thereon can not dropped out when Assembly ﹠Disassembly outward, and is safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the mansion view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of Electricity collecting frame, comprise permanent seat 3, boxed rod 1, lower link 2 and brush 7, the axle 10 perpendicular with it arranged on described permanent seat 3, be with shaft seat 9 on the described axle 10, described shaft seat 9 hinge joint boxed rod 1 and lower links 2, upper and lower connecting rod can rotate around axle 10, and action is flexible, nargin is big; The other end hinge joint tip-lever support 8 of described boxed rod 1 and lower link 2, boxed rod 1 and lower link 2 form hollow structure by front panel 12 and rear panel 13 respectively, built-in extension spring 5, can avoid in stroke and the contacting of foreign object, prevent the generation of short circuit accident, described extension spring 5 one ends are fixed on the last hangers 11 of boxed rod 1, the other end is fixed on the following hangers 21 of lower link 2, in order to power upwards to be provided, brush 7 is close on the electric rail level with suitable pressure steadily to be slided, electrically contact good, boxed rod 1 is respectively equipped with projection 4 with the opposite face of lower link 2, by the restriction of projection 4, the opposite face of two connecting rods can directly be close to, and the upward force that spring is provided remains on certain value; Be inserted with push rod 6 on the described tip-lever support 8, described push rod 6 connects brush 7, the contact surface of its top and brush 7 is circular-arc, make brush 7 flexible with contacting of push rod 6, it is unimpeded to walk, and no jam phenomenon takes place, and the boss 61 of push rod 6 tail ends matches with tip-lever support 8 circular hole inner end surfaces 81, push rod 6 and brush 7 fixed thereon can not dropped out when Assembly ﹠Disassembly outward, safe and reliable.
