Abstract
The utility model relates to a self-mounting pivot-point type lifter, which belongs to a hoisting machine for construction. The utility model comprises an overbridge whose one end is hinged with a tower body, and the other end is fixedly connected with a supporting point which is clamped on buildings; steel cables on a winding engine reel drum are passed through a tower body pulley and an overbridge pulley and is buckled with a lifting frame used for hoisting weights; a hydraulic cylinder of a tower body is hinged with the bottom part of the tower body; a hydraulic cylinder of an overbridge is respectively hinged with the tower body and the overbridge. Both the vertical and lying positions of the tower body and the closing and opening of the overbridge are automatically completed. The utility model has the characteristics of high anti-incline caterpillar, stability, rigidity, convenient and safe operation, reasonable integration stress, and simple structure.
Description
The utility model relates to the elevator machinery in a kind of building operation.
In building operation, elevator machinery is indispensable material handling machinery.In the low-rise building installation, elevator machinery has masts type, derrick formula and bar crane voluntarily; Masts type, derrick formula elevator machinery exists the alerting ability deficiency, moves difficulty, and service radius is little, poor safety performance; Bar crane comprises crawler type, rubber-tyred, truck mounted three class hoisting cranes voluntarily, and they exist mechanism's complexity, setup time is long, executive cost is high, and there is strict demand the work-yard, can't be used for the building operation in rural area, small towns.In the construction of multilayer and high level, the tower crane of use exists complex structure again, stressed irrational distribution, and the site assembly time is long, and is strict to the work-yard, and deficiencies such as power supply must be provided.Therefore, when at present widely used all kinds of elevator machineries all exist erection cost, shift that difficulty, poor safety performance, range of use are limited to, propulsion source is single, shortcomings such as manufacturing cost height.
The purpose of this utility model provides a kind of quick and easy for installation, and safety performance is superior, and stressed distribution is reasonable, shifts rapidly, is not subjected to the fulcrum type of the installation certainly hoisting crane of working space landform and propulsion source kind restriction.
Technical solution of the present utility model is: a kind of from the pedestal that driving, winch, alighting gear and the body of the tower bottom of setting up on overline bridge that the fulcrum type hoisting crane comprises that body of the tower, an end link to each other with body of the tower, the overline bridge are installed, its difference from prior art is: the other end of overline bridge is connected in the supporting-point that is stuck on the building, be hinged with hydraulic actuating cylinder between overline bridge and body of the tower and body of the tower and the pedestal, hydraulic cylinder power is provided by the hydraulic actuating cylinder engine installation.
Be wound with steel rope on the lifting drum that links with propulsion source, the free end of steel rope passes the body of the tower pulley, the overline bridge pulley is buckled and lain on the alighting gear, and alighting gear is used for hook block floor or other building material.Form the hydraulic actuating cylinder engine installation by the Hydraulic Pump of drive power source, its propulsion source can be shared with the winch propulsion source, the hydraulic actuating cylinder engine installation links to each other with hydraulic actuating cylinder with control cock by pressure oil pipe, overline bridge hydraulic actuating cylinder two ends are hinged closing up and strut with the control overline bridge with body of the tower top and overline bridge front portion respectively, the body of the tower hydraulic actuating cylinder is hinged mutually with body of the tower, with the automatic setting that realizes body of the tower with keep flat.Certainly, the setting of body of the tower with keep flat also and can affect steel rope to realize by winch.
This machine both can have been finished the crane lifting service of floor or other building material separately, also can use to finish the loading and unloading transportation and the crane lifting service of floor or other building material with the floor combined vehicle.
The utility model has the advantages that: the setting of body of the tower, strutting all of overline bridge finished automatically, shortened the set-up time of hoisting crane greatly, reduced labour intensity, and actv. has been avoided hidden dangers such as body of the tower setting, overline bridge lifting.One end of overline bridge is supported on the building by supporting-point, the other end is supported on the body of the tower, overline bridge constitutes a single supported beam form, only be subjected to positive pressure in the body of the tower working process, make the stressed very reasonable of overline bridge, body of the tower, because the overline bridge that is supported on the building can play reliable support to body of the tower, make body of the tower more firm again, deviation resistance, the stability of hoisting crane improve greatly, and body of the tower, a day bridge construction are able to effective simplification.Thereby saved materials, alleviated deadweight.The both available diesel engine of the propulsion source that links to each other with winch, hydraulic power unit, spark ignition engine, also can adopt electrical motor and other engine, propulsion source is unrestricted, and the range of use of hoisting crane is further expanded, and is specially adapted to the building operation in rural area, small towns.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing is of the present utility model a kind of from the enforcement structural representation that the fulcrum type hoisting crane is installed.
Hinged body of the tower (1) on pedestal (12) links to each other with overline bridge (5) by hinge (4), hinge (4) is a two-dimentional hinge, so that overline bridge (5) both can close up with body of the tower (1), strut, with can rotate around body of the tower (1), body of the tower, overline bridge all adopts truss structure, make integral rigidity better, more economize with material, be wound with steel rope (2) on winch (14) reel that joins with propulsion source, pulley and the pulley on the overline bridge (5) that the free end of steel rope (2) passes on the body of the tower (1) lie on the alighting gear (8) of framed structure, alighting gear is used for hook block building material (9), set up the driving (6) that to move along the overline bridge length direction on the overline bridge (5), reel in the driving and steel wire rope hook be used to sling floor or other material parallel motion, the other end of overline bridge (5) is supported on the supporting-point (7), and supporting-point is stuck on the building (15).
Hydraulic actuating cylinder engine installation (13) is formed by propulsion source and hydraulic pump combination, hydraulic actuating cylinder engine installation (13) is connected with body of the tower hydraulic actuating cylinder (10) with overline bridge hydraulic actuating cylinder (3) respectively with control cock by pressure oil pipe (11), the two ends of body of the tower hydraulic actuating cylinder (10) are hinged with the bottom and the pedestal (12) of body of the tower (1) respectively, with the setting that realizes body of the tower with set level, the two ends of overline bridge hydraulic actuating cylinder (3) are hinged mutually with overline bridge (5) and body of the tower (1) respectively, to finish strutting automatically and close up of overline bridge.
Claims (2)
1. one kind from driving, winch, the alighting gear that sets up on overline bridge that the fulcrum type hoisting crane comprises that body of the tower, an end link to each other with body of the tower, the overline bridge, the pedestal that reaches the body of the tower bottom are installed, it is characterized in that: the other end of overline bridge is connected in the supporting-point that is stuck on the building, be hinged with hydraulic actuating cylinder between overline bridge and body of the tower and body of the tower and the pedestal, hydraulic cylinder power is provided by the hydraulic actuating cylinder engine installation.
