The specific embodiment
Fig. 1 is the embodiment of self-locking single-unit point hoist apparatus of the present invention, shows the integral structure that is installed on the mechanical floor guide rail, and Fig. 2 is the scheme drawing of disassembling of the present invention.Among the figure, guide rail 2 is necessary facilities that various suspender members are installed on the mechanical floor, slide plate briquetting 1 symmetry that two block sizes equate is installed on guide rail 2 both sides, the contact surface of slide plate briquetting and guide rail matches, which is provided with several tapped bore, slide plate 4 is provided with and the corresponding tapped bore of slide plate briquetting 1 upper screwed hole, with screw slide plate briquetting 1 and slide plate 4 is fastened as one, and is convenient to self-locking single-unit point hoist apparatus and moves on guide rail.
Center at slide plate 4 is provided with through hole, the external diameter of rotating disk 8 and the equal diameters of through hole, and rotating disk 8 is installed in the through hole of slide plate 4 and can 360 degree rotation; Rotating disk 8 is provided with perforation, and the upper end of rope sheave support 5 is passed from the perforation of rotating disk 8, its upper surface contact guide rail 2; Axle 3 is captiveed joint rope sheave support 5 with rotating disk 8; In the present embodiment, the upper surface of rope sheave support 5 is provided with plan-convex 10 and inclined-plane 11 (as shown in Figure 2); Rope sheave 7 is installed on rope sheave support 5 lower ends by wheel shaft 6.
The through hole at slide plate 4 centers of present embodiment has groove (as shown in Figure 3, Figure 4), rotating disk 8 upper ends are provided with step, through hole groove diameter in stepped diameters and the slide plate 4 equates, after rotating disk 8 inserts through hole, the step of rotating disk 8 upper ends is stuck in slide plate 4 grooves and with slide plate 4 planes and coincide, and promptly rotating disk 8 becomes same plane with the last plane of slide plate 4.
As shown in Figure 2, rotating disk has axis hole on 8 sides, and cooresponding axis hole is arranged on the rope sheave support 5, the axis hole place is provided with pad 9, and axle 3 passes two axis holes rope sheave support 5 is connected with slide plate 4, also is connected with guide rail 2 simultaneously, rotating disk 8 rotates in slide plate 4, drives 5 servo-actuateds of rope sheave support simultaneously.
Fig. 5 is that the rope sheave support is locked view in the embodiments of the invention on guide rail, shows the self-locking single-unit point hoist apparatus self-lock mechanism.Wheel shaft 6 passes rope sheave support 5 lower end circular holes and rope sheave 7 centre holes, makes rope sheave 7 be installed in rope sheave support 5 lower ends, and rope sheave 7 outer rings are provided with groove, are wound with steel rope in the groove.
When the wire rope hanging weight, steel rope pulls down, because axle 3 arrives the arm of force of rope sheave support plan-convex 10 and guide rail contact surface much larger than axle 3 to the arm of force of wheel shaft 6, therefore produce very big positive pressure, the plan-convex 10 of rope sheave support 5 withstands guide rail 2 bottom surfaces, as long as the product of the ratio of two arm of force power and friction coefficient is greater than 1, then friction force will be realized the self-locking location greater than lateral pull.When needing displacement, will hang weight and unload, plan-convex 10 promptly leaves guide rail 2 bottom surfaces, promotes rope sheave support 5, and its inclined-plane 11 is parallel with guide rail 2 bottom surfaces, can realize any running fix of self-locking single-unit point hoist apparatus.
The present invention is a portable self-locking single-unit point hoist apparatus of new generation, utilizes lever principle, by being installed in the rope sheave support on the guide rail, utilize two slide rail briquettings can realize hanging weight along guide rail move, location and self-locking.Easy to operate, safe and reliable, time saving and energy saving, improved work efficiency greatly.
