Abstract

The utility model discloses a cantilever crane. An upper base and a lower base, namely a base I and a base II, are arranged on an upright post; bearings are assembled in the base I and the base II; the base II is transversely fixed at one end of a cantilever suspension arm rack; the base I is fixed at one ends of a cantilever hauling rod I and a cantilever hauling rod II; the other ends of the cantilever hauling rod I and the cantilever hauling rod II are fixed on the upper side of the cantilever suspension arm rack; and an electric hoist is arranged on the lower side of the cantilever suspension arm rack. According to the bearings assembled in the base I and the base II, the cantilever crane can smoothly rotate. According to the design of the two cantilever hauling rods, the stability and flexibility of the cantilever crane are improved, an integrated cantilever shaft is replaced by two bases with bearings, and the cantilever crane is convenient to maintain, mount and manufacture.

Description

Cantilever crane
Technical field
The utility model relates to the lifting tool in mechanical equipment, is specifically related to a kind of cantilever crane.
Background technology
Cantilever crane is a kind of light lifting equipment in modern production, is generally made up of column, revoliving arm device for revolving and driving and electric block, and one end of revoliving arm is laterally arranged on column, easily causes one end fixed end absent-mindedness, initiation potential after long-time use.The version that has the fixing welding in angle, right angle reinforced rib between revoliving arm and column in prior art, when revoliving arm rotation, fixing reinforced rib alerting ability is little, easily damages, and reduces cantilever crane flexibility of operation.Or revoliving arm device for revolving and driving is the revoliving arm being fixed on projecting shaft, the difficulty that this integral structure form has increased maintenance and installed, increases cost.
Utility model content
Utility model object: the utility model is in order to solve the deficiencies in the prior art, provide a kind of firmly, cantilever crane flexibly.
Technical scheme: a kind of cantilever crane, on column, install lower two bases, be respectively base I and base II, in base I and base II, is all furnished with bearing, base II is laterally fixed wtih one end of cantilever crane jib, base I is fixed wtih one end of cantilever crane pull bar I and cantilever crane pull bar II, and the other end of described cantilever crane pull bar I and cantilever crane pull bar II is fixed on described cantilever crane jib upside, and described cantilever crane jib downside is equipped with electric block.Electric block can be at cantilever crane jib downside transverse shifting.
As optimization, described cantilever crane pull bar I is longer than cantilever crane pull bar II, between cantilever crane pull bar I, cantilever crane pull bar II and cantilever crane jib, forms obtuse-angled triangle.Leg-of-mutton cantilever crane Tiebar structure contributes to the firm of cantilever crane.
As optimization, described cantilever crane pull bar I is fixedly connected on cantilever crane jib upside apical position, and described cantilever crane pull bar II is fixedly connected on cantilever crane jib upside midway location.
As optimization, described cantilever crane pull bar I and cantilever crane pull bar II are steel rope pull bar.Cantilever crane pull bar adopts steel rope, while being convenient to install, regulates, and is also convenient to later period maintenance, maintenance.
As optimization, between described base I and base II and column, be fixedly connected with by anchor ear.Adopt circular anchor ear and workshop column to be welded and fixed, be convenient to fabrication and installation, also increased safety in utilization.
As optimization, anti-collision rubber is equipped with in the other end both sides of described cantilever crane jib.Crashproof between two cantilever cranes between adjacent upright posts and cantilever crane and column.
Beneficial effect: the bearing of joining in the utility model base I and base II can ensure cantilever crane Rotate 180 ° smoothly.The steadiness of cantilever crane has been strengthened in the design of two cantilever crane pull bars, alerting ability, and the base with bearing replaces the projecting shaft of one with two, maintenance, install, manufacture all more convenient.
Brief description of the drawings
Fig. 1 is the utility model cantilever crane structure schematic diagram;
Fig. 2 is the birds-eye view of Fig. 1.
Detailed description of the invention
As Fig. 1, a kind of cantilever crane shown in 2, comprise the steel column column 1 of vertical placement, steel column column 1 is the cylindrical pillar connecting with reinforced rib between two, two bases are housed on one of them cylindrical pillar, be respectively the base II3 that is contained in the base I2 of top and is contained in below, base I2 and base II3 are welded on cylindrical pillar by anchor ear 8, one end of cantilever crane jib 4 is fixed on base II3, cantilever crane jib 4 is that horizontal direction is vertical with steel column column 1, can rotate around steel column column 1, the upper end of steel rope cantilever crane pull bar I5 and steel rope cantilever crane pull bar II6 is fixedly mounted on base I2, steel rope cantilever crane pull bar I5 and steel rope cantilever crane pull bar II6 lower end are fixedly connected on cantilever crane jib 4 upsides, cantilever crane jib 4 downsides are equipped with electric block 7 that can transverse shifting, anti-collision rubber 9 is equipped with in cantilever crane jib 4 both sides, top.
Cantilever crane pull bar I5 is longer than cantilever crane pull bar II6, the other end of cantilever crane pull bar I5 is connected to cantilever crane jib 4 positions, upside top, the other end of cantilever crane pull bar II6 is connected to cantilever crane jib upside midway location, between cantilever crane pull bar I5, cantilever crane pull bar II6 and cantilever crane jib 4, forms firm triangle.
Cantilever crane pull bar I5, cantilever crane pull bar II6 and cantilever crane jib 4 can carry out 180 ° of rotations around column 1 by the bearing of base I2 and base II3 mounted inside.
