Abstract
The utility model provides a detachable rope warding-off device for a load trolley. The load trolley at least comprises a transverse beam and two vertical beams, wherein the two ends of the two vertical beams are movably mounted on a cargo boom rack through front and back walking wheels; the transverse beam is arranged between the two vertical beams and are fixedly connected with the two vertical beams; the transverse beam is provided with a pulley assembly, a steel rope and a lifting hook; the pulley assembly comprises a pulley seat mounted on the transverse beam; two pulleys which are arrayed in parallel are fixedly arranged in front and back of the pulley seat respectively by a pulley shaft; a rope warding-off plate is outwards connected with each of the two sides of the two pulleys on the pulley seat; each rope warding-off plate is transversely provided with a detachable pin shaft which is provided with an opening pin and is located outside wheel edges of the two pulleys. The detachable rope warding-off device for the load trolley has the characteristics of reasonable structure, safety and reliability, convenience for installation and detachment, capability of effectively preventing the steel wire rope from jumping out of a pulley groove to cause accidents and the like.
Description
Technical field
The present invention relates to a kind of loading trolley of tower machine, belong to heavy-duty machinery technical field.
Background technology
Tower machine, " tower crane " is called for short, and claims again " tower crane ", is a kind of weight-lifting equipment for building operation; Loading trolley is the part on tower machine.Loading trolley is arranged on elevator boom rack, and can move with respect to elevator boom rack; Assembly pulley and steel cable and suspension hook are installed, for towing weight on loading trolley.
Existing loading trolley comprises crossbeam and two longerons, former and later two road wheel component capable of movable installeds are passed through on elevator boom rack in the two ends of described two longerons, described crossbeam is arranged between two longerons, and be fixedly connected with described two longerons, described assembly pulley and steel cable and suspension hook are all arranged on described crossbeam; Steel rope is wherein the consumable accessory of tower machine, is the pith that affects tower machine safety.Wire line thimble on existing tower machine loading trolley is around two pulleys side by side, and the both sides of pulley only rely on rope blocking plate to play the anticreep effect of steel rope; But when loading trolley operation working process, steel rope is jumped out pulley and still happened occasionally, once steel rope is jumped out pulley and steel rope easily occurs rubbed when suspension hook hoists, very easily cause safety misadventure.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, safe and reliable, and Assembly &Disassembly is convenient, can effectively prevent that steel rope from jumping out the detachable ward off rope device of the loading trolley that pulley groove causes the accident.
The purpose of this utility model completes by following technical solution, described loading trolley, which comprises at least crossbeam and two longerons, former and later two road wheel component capable of movable installeds are passed through on elevator boom rack in the two ends of described two longerons, described crossbeam is arranged between two longerons, and be fixedly connected with described two longerons, on described crossbeam, be provided with pulley assembly and steel cable and suspension hook, it is characterized in that described pulley assembly comprises that one is arranged on the pulley base on crossbeam, the front and back of this pulley base are fixed with two pulleys side by side with sheave shaft respectively, pulley base is positioned at the both sides of two pulleys respectively to being externally connected with a rope blocking plate, and on described rope blocking plate, laterally dispose with spring cotter, be positioned at two detachable bearing pins outside pulley wheel edge.
The tight rope ratchet device of using and the Anti-breaking rope device that prevents from blocking crane arm are installed on the crossbeam of described pulley base one side.
The utlity model has rational in infrastructurely, safe and reliable, Assembly &Disassembly is convenient, can effectively prevent that steel rope from jumping out the features such as pulley groove causes the accident.
Accompanying drawing explanation
Fig. 1 is loading trolley structural representation described in the utility model.
Fig. 2 is ward off rope device structural representation described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, loading trolley described in the utility model, which comprises at least crossbeam 1 and two longerons 2, former and later two road wheel 3 component capable of movable installeds are passed through on elevator boom rack in the two ends of described two longerons 2, described crossbeam 1 is arranged between two longerons 2, and be fixedly connected with described two longerons 2, on described crossbeam 1, be provided with pulley assembly and steel cable and suspension hook.
Shown in Fig. 2, described pulley assembly comprises that one is arranged on the pulley base 4 on crossbeam 1, the front and back of this pulley base 4 are fixed with two pulleys 6 side by side with sheave shaft 5 respectively, pulley base 4 be positioned at two pulleys 6 both sides each to being externally connected with a rope blocking plate 7, and on described rope blocking plate 7, laterally dispose with spring cotter 8, be positioned at two pulleys 6 and take turns the detachable bearing pin 9 outside edge.
The tight rope ratchet device 10 of using and the Anti-breaking rope device 11 that prevents from blocking crane arm are installed on the crossbeam 1 of pulley base 4 one sides described in the utility model.
