Abstract
A standard section connection sleeve of a tower crane relates to the technical field of building machinery. An upper connection sleeve and a lower connection sleeve are arranged on a main branch of each standard section, two adjustable standard sections are connected through bolts, a sink platform is arranged on an inner ring at the upper end of each upper connection sleeve, and a chamfer is arranged on an outer ring at the lower end of each lower connection sleeve. The sink tables and the chamfers of two adjacent standard sections are connected in matching mode. The lower ends of eight lower connection sleeves on four main branches under the standard sections are chamfered, and the sink tables are turned on the inner rings at the upper ends of the eight upper connection sleeves, so that the adjacent two standard sections can be conveniently led in in installation. Positioning size of the connection sleeves welded on the main branches of the standard sections is adjusted to enable the connection sleeves to be in better face contact with the upper connection sleeves of the standard sections at the lower end. The standard section connection sleeve has the effect of quick positioning and installation in section increase of a tower body, and friction produced by better face contact of the upper connection sleeves and the lower connection sleeves can offset a part of torsion, so that shearing force received by the bolts is reduced, and integral strength and safety of the tower crane are improved.
Description
Technical field
The utility model relates to the vehicle for construction technical field, is a kind of column crane mast section coupling sleeve specifically.
Background technology
The body of the tower of tower crane is to be formed by connecting by high strength bolt by base section, reinforcement joint and standard knot, is the important support link that bed rearrangement tower machine is rised sheer from level ground.The huge moment of torsion that tower crane produces in the course of the work adheres to the building except fraction passes to by the attached wall strut, has all passed to tower crane self in addition greatly.The moment of torsion that how to reduce or produce when eliminating the rotation of the big arm of tower crane reduces the shearing force to tie bolt, for the mechanical strength that strengthens tower crane, improves security of products and can seem particularly important.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of column crane mast section coupling sleeve, by increasing the area of contact of body of the tower standard knot, to increase the friction force between the standard knot, reduce the suffered shearing force of high strength bolt, improve the security of products energy.
For achieving the above object, the master of standard knot of the present utility model props up and is provided with coupling sleeve and lower link cover, and adjacent two standard knots connect by high strength bolt, on connect the set upper side inner ring heavy stand arranged, there is chamfering lower link cover outer ring, lower end, and heavy stand and the chamfering of adjacent two standard knots are connected.
Eight lower link cover outer ring, lower end chamferings that the utility model props up four masters in standard knot below, and eight gone up connect set upper side inner ring car and go out heavy stand, when installing, adjacent two standard knots are convenient to introduce; Adjust the lower link cover and be welded on the location dimension that the standard knot master props up, can be with better face with upward connecting of lower end standard knot and contact.
The utility model compared with prior art, when the body of the tower supernumerary segment, can play the effect of quick location and installation, and the friction force that the face contact that upper and lower coupling sleeve is good produces can be offset a part of torsion, thereby reduces the suffered shearing force of bolt, increases bulk strength and the safety of tower crane.
Description of drawings
Fig. 1 is the utility model standard knot integral installation scheme drawing.
Fig. 2 is the I-I enlarged drawing of Fig. 1.
Fig. 3 is A-A generalized section among Fig. 2.
The specific embodiment
As shown in Figure 1, body of the tower is to be assembled by several standard knots 1, and per two standard knots 1 all adopt the high strength bolt of 8 10.9 grades M30 to connect and tighten up, and sequence number 2 is propped up for the master of standard knot 1.
As shown in Figure 2, Fig. 2 is the I-I enlarged drawing of Fig. 1.The master of standard knot props up and is provided with coupling sleeve 3 and lower link cover 4, adjacent two standard knots connect by high strength bolt 5, last coupling sleeve 3 upper end inner rings have heavy stand 6, and lower link is overlapped outer ring, 4 lower end chamfering 7, and heavy stand 6 and the chamfering 7 of adjacent two standard knots 1 are connected.
During installation, the utility model design has the lower link cover 4 and the last coupling sleeve 3 that has heavy stand 6 of chamfering 7, can not only play the introduction effect, shorten the set-up time, and the good face contact of coupling sleeve can produce certain friction force, with counteracting torsion, thereby reduce the suffered shearing force of bolt.The utility model also can strengthen the whole torsional strength of tower crane when prolonging its service life, improve the safety when using.
