Adopt above structure, there is between two assembly pulleys and adjacent side plates the angle of opposite angles, hoisting crane operating room can be prevented, suspension hook group steel rope bracket, and reduce steel rope abrasion, extension device service life.
Preferably, described second assembly pulley comprises two symmetrically arranged second pulleys, two second pulleys are supported between the side plate of both sides by the second sheave shaft, second pulley is obliquely installed, have angle-α between its radial center axis and side plate, described second sheave shaft and the first sheave shaft are positioned in same level.This structure makes two pulley block structures consistent, and convenient manufacture, is conducive to saving production cost, and improves the mutual property of parts.
Preferably, corresponding first sheave shaft of described side plate and the second sheave shaft end position are provided with sheave shaft via hole, and this sheave shaft via hole is obliquely installed, and to facilitate installation sheave shaft, and comparatively reasonably realizes the inclination of assembly pulley.
Preferably, for convenience of dead sheave axle, prevent it from rotating, be provided with former outside described sheave shaft via hole, this former and side plate are fixed, and are provided with square opening in the middle part of it, the first sheave shaft and the second sheave shaft stretch out the end of side plate and this square opening suitable.
Preferably, the angle of angle α is determined with steel rope position on reel according to suspension hook dead sheave when driving a vehicle limes superiors, is generally 3 ~ 8 °, in the present invention preferably 5 °.
Preferably, be provided with suspension hook transverse axis below described first sheave shaft, these suspension hook transverse axis two ends are installed on the side plate of both sides, and suspension hook transverse axis is arranged with suspension hook, and this topology layout is reasonable, convenient for assembly.
The invention has the beneficial effects as follows:
1, structure is simple, novel, and cost aspect is comparatively economical;
2, easy for installation, installation method similar to traditional suspension hook can be adopted;
3, with traditional hanger components highly versatile, except side plate, substantially can realize parts exchange;
4, reduce groove skipping of steel rope while risk, ensure the reliability that hoisting crane uses;
5, decrease steel rope abrasion, effectively extend the service life of steel rope.

Fig. 3 is the mounting structure schematic diagram of biside plate in the present invention;
Fig. 4 is using state reference diagram of the present invention.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
A kind of suspension hook group pulley installation structure as shown in Figures 1 to 4, comprise two blocks of side plates be oppositely arranged 1 and be arranged on the first assembly pulley 2 and the second assembly pulley 3 between biside plate 1, side plate 1 is vertically arranged, by the first sheave shaft 22 between biside plate 1, second sheave shaft 32 and 5 three, suspension hook transverse axis are connected and fixed, side plate 1 structure roughly triangular in shape, bottom is protruded downwards, second sheave shaft 32 and the first sheave shaft 22 are positioned in same level, suspension hook transverse axis 5 is positioned at below the first sheave shaft 22 and the second sheave shaft 32 place horizontal surface, these suspension hook transverse axis 5 two ends are bolted on both sides side plate 1, suspension hook 6 is provided with by bearing carrier ring in the middle part of suspension hook transverse axis 5.
As seen from Figure 2, described first assembly pulley 2 and the second assembly pulley 3 specular are arranged, this first assembly pulley 2 comprises two symmetrically arranged first pulleys 21, two first pulleys 21 are supported between both sides side plate 1 by the first sheave shaft 22, antifriction-bearing box is provided with between first pulley 21 and the first sheave shaft 22, first pulley 21 is obliquely installed, and has the angle α of 3 ~ 8 ° between its radial center axis and side plate 1, is preferably 5 ° in the present invention.
Described second assembly pulley 3 structure is identical with the first assembly pulley 2, and specular each other, this second assembly pulley 3 comprises two symmetrically arranged second pulleys 31, two second pulleys 31 are supported between both sides side plate 1 by the second sheave shaft 32, second pulley 31 is obliquely installed, and between its radial center axis and side plate 1, tool angle is the angle of-α.
