Abstract
The invention discloses a detachable propeller strut for crane. The detachable propeller strut for crane comprises an upper support and a lower support. The top of the upper support is provided with an assembly pulley. The upper support comprises a vertical upper link and an upper strut, one end of which is connected with the upper link. The upper support comprises a vertical lower link and a lower struct which is connected with the upper link through a connecting rod. The bottoms of the upper link and the upper strut are detachably connected with the tops of the lower link and the lower strut. The above detachable propeller strut for crane divides a whole support into the upper support and the lower support which are detachably connected with each other. During transportation, the upper support is dismounted so as to reduce the height of the propeller strut. When in use, the upper support only needs to be installed on the lower support. On the prerequisite of guaranteeing safe reliability, the detachable propeller strut for crane is convenient to transport and install.
Description
Technical field
The present invention relates to elevator machinery technical field, particularly relate to a kind of Detachable propeller strut being applicable to hoisting crane.
Background technology
At present, hoisting crane is many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, also known as crane, belongs to material carrying machine.Jib-type crane can circle and on idle job, be used for the work such as outdoor handling and installation.
Shears is requisite component in jib-type crane, the general front strut be connected with pull bar by upright pull bar and upper end forms, pull bar and front strut form " people " font, therefore title Shears, pulley assembly is installed on the top of Shears, arrange winch assembly bottom Shears, copper rope is by the pulley assembly traction jib on Shears top.But the height of Shears is general all higher, causes the volume of whole hoisting crane comparatively large, be not easy to transport and install.
Summary of the invention
The object of the present invention is to provide a kind of Detachable propeller strut for hoisting crane, it has easy accessibility, convenient transportation and safe and reliable feature, adopts the hoisting crane Problems existing of Shears form to solve upper rotary column in prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of Detachable propeller strut for hoisting crane, it comprises upper bracket and lower bracket, the top of described upper bracket arranges pulley assembly, described upper bracket comprises the upper strut that upright top rod is connected with top rod with one end, described lower bracket comprises the lower supporting rod that upright lower link is connected by pipe link with top rod with top, and the top of the bottom of described top rod and upper strut and lower link and lower supporting rod is dismantled and assembled to be connected.
Especially, between described top rod and upper strut, parallel interval is fixedly installed the stirrup of at least one.
Especially, the bottom of described top rod and upper strut is all connected with upper junction plate, described upper junction plate offers through hole, top corresponding to lower link and lower supporting rod is all connected with lower connecting plate, described lower connecting plate offers through hole, and upper bracket is connected with lower bracket through the through hole of upper and lower connecting panel by bearing pin.
Especially, described upper strut connects anti-hypsokinesis connecting rod.
Especially, described pulley assembly comprises first and second clamp, sheave shaft and pulley, installs sheave shaft, described sheave shaft is arranged several pulleys between first and second clamp described by bolt and packing ring.
Beneficial effect of the present invention is, compared with prior art integral support is divided into upper and lower support by the described Detachable propeller strut for hoisting crane, and by dismantled and assembled for upper and lower support connection, during transport, upper bracket is removed, reduce the height of Shears, in use, only need upper bracket be installed on lower bracket, under the prerequisite ensureing safe reliability, there is the advantage of being convenient to transport and install.
