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 the elevator machinery technical field, relate in particular to a kind of removable Shears that is 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, claims crane again, belongs to material handling machinery.Jib-type crane can circle and on idle job, be used for work such as open-air loading and unloading and installation more.
Shears is a requisite member in the jib-type crane; Generally form by upright pull bar and upper end and pull bar bonded assembly front strut; Pull bar and front strut constitute " people " font, so claim Shears, pulley assembly is installed on the top of Shears; The Shears bottom is provided with the winch assembly, and the copper rope is through the pulley assembly traction jib on Shears top.But the height of Shears is generally all higher, causes the volume of whole hoisting crane bigger, is not easy to transportation and installation.
Summary of the invention
The object of the present invention is to provide a kind of removable Shears that is used for hoisting crane, it has easy accessibility, convenient transportation and safe and reliable characteristics, to solve the problem that last rotary column adopts the hoisting crane of Shears form to exist in the prior art.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of removable Shears that is used for hoisting crane; It comprises upper bracket and lower bracket; The top of said upper bracket is provided with pulley assembly; Said upper bracket comprises strut on upright top rod and an end and the top rod bonded assembly, and said lower bracket comprises upright lower link and top and top rod through pipe link bonded assembly lower supporting rod, the dismantled and assembled connection of top of the bottom of said top rod and last strut and lower link and lower supporting rod.
Especially, parallel interval is set with at least one stirrup between said top rod and the last strut.
Especially; The bottom of said top rod and last strut all is connected with upper junction plate; Offer through hole on the said upper junction plate; Top corresponding to lower link and lower supporting rod all is connected with lower connecting plate, offers through hole on the said lower connecting plate, and the through hole that bearing pin passes upper and lower connecting panel is connected upper bracket with lower bracket.
Especially, said going up connects anti-hypsokinesis connecting rod on the strut.
Especially, said pulley assembly comprises first and second clamp, sheave shaft and pulley, through bolt and packing ring sheave shaft is installed between said first and second clamp, and several pulleys are set on the said sheave shaft.
Beneficial effect of the present invention does, the compared with prior art said removable Shears that is used for hoisting crane is divided into upper and lower support with integral support, and with the dismantled and assembled connection of upper and lower support; During transportation, upper bracket is removed, reduced the height of Shears; In use; Only need upper bracket is installed on the lower bracket and get final product, under the prerequisite of assurance safe reliability, have and be convenient to the advantage of transporting and installing.
Description of drawings
Fig. 1 is the structural representation of the removable Shears that is used for hoisting crane that provides of the specific embodiment of the invention 1;
