Abstract
The utility model discloses a kind of electric power self extending formula lift, comprise base and be fixed on the shell on base, center vertical is fixed with the central tube of rectangle in the enclosure, extension ladder is set with in central tube, every section of end of described extension ladder is respectively arranged with resilient key, central tube both sides are in the enclosure respectively arranged with transmission mechanism, and the friction roller of transmission mechanism is symmetricly set on extension ladder both sides, and friction roller coordinates with resilient key and compresses or discharge.The utility model utilizes symmetrical friction roller to promote extension ladder, makes its automatic lifting, without the need to manual operation.The axle of friction roller is positioned at fork end, and progress mechanism can pull fork to move to center, thus no matter how extension ladder changes because of the width of telescopic process every section, and fork can guarantee that both sides friction roller is fitted in extension ladder surface all the time.Utilize the mode of friction roller elasticity of compression pin, make extension ladder can indentation, can self-supporting after expansion.
Description
Technical field
The utility model relates to lift improvement opportunity in power system, is specifically related to a kind of electric power self extending formula lift.
Background technology
In power system, often need to use lift to carry out climbing operation.Existing lift or be fixed on as vehicle-mounted lifting ladder on car body, or be that Portable lifting is terraced, be all widely used with telescopic escalator structure.The lifting process of existing telescopic lift must manual operation, and adjustable height can not arbitrarily control, and for larger lift, has singlely been difficult to stretch and has three-dimensionally placed operation, troublesome poeration.
Utility model content
The purpose of this utility model is to provide a kind of lift with self extending function, realizes convenient manipulation, saves the effect of manpower.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of electric power self extending formula lift, comprise base and be fixed on the shell on base, center vertical is fixed with the central tube of rectangle in the enclosure, extension ladder is set with in central tube, every section of end of described extension ladder is respectively arranged with resilient key, central tube both sides are in the enclosure respectively arranged with transmission mechanism, the friction roller of transmission mechanism is symmetricly set on extension ladder both sides, and friction roller coordinates with resilient key and compresses or discharge.Described transmission mechanism, the output shaft of its motor is provided with drive sprocket, and the rotating shaft of friction roller is provided with driven sprocket, and drive sprocket is connected by chain drive with driven sprocket, and is provided with strainer.Strainer is that wall is hinged with tensioning pull bar in the enclosure, and is connected with spring, and the end of tensioning pull bar is provided with regulating wheel.Be hinged with fork on the upside of portion in the enclosure, described friction roller is arranged on fork end.The bottom of described shell is provided with universal wheel.
The beneficial effects of the utility model are: utilize symmetrical friction roller to promote extension ladder, make its automatic lifting, without the need to manual operation.The axle of friction roller is positioned at fork end, and progress mechanism can pull fork to move to center, thus no matter how extension ladder changes because of the width of telescopic process every section, and fork can guarantee that both sides friction roller is fitted in extension ladder surface all the time.Utilize the mode of friction roller elasticity of compression pin, make extension ladder can indentation, can self-supporting after expansion.The utility model may be used for vehicle-mounted or ground translation use, effective, is applicable to promotion and implementation.
Accompanying drawing explanation
Fig. 1 is internal construction schematic diagram of the present utility model;
Fig. 2 is that the A of Fig. 1 is to structural representation;
Fig. 3 is that the B of Fig. 1 is to structural representation.
In figure, label 1 is base, and 2 is shell, cylinder centered by 3,4 is extension ladder, and 5 is motor, and 6 is drive sprocket, 7 is driven sprocket, and 8 is friction roller, and 9 is balance staff, 10 is regulating wheel, and 11 is tensioning pull bar, and 12 is spring, 13 is chain, and 14 is fork, and 15 is rotating shaft, 16 is resilient key, and 17 is shell fragment, and 18 is rubbing surface.
Detailed description of the invention
Be be fixed with shell 2 on base 1 see the electric power self extending formula lift in Fig. 1, figure, shell 2 is highly applicable to normal person's spanning height.Base can arrange universal wheel 1 time so that translation uses.
In shell 2, center vertical is fixed with the central tube 3 of rectangle, is set with extension ladder 4 in central tube 3.See Fig. 2, every section of end of extension ladder 4 is respectively arranged with resilient key 16.In Fig. 3, extension ladder side is provided with pin-and-hole, resilient key 16 is drawn from pin-and-hole, is provided with shell fragment 17 in extension ladder inner chamber, and shell fragment 17 one end is fixed on resilient key 16.
In Fig. 1 and Fig. 2, central tube 3 both sides in shell 2 are respectively arranged with transmission mechanism, and the friction roller 8 of transmission mechanism is symmetricly set on extension ladder 4 both sides, and friction roller 8 coordinates with resilient key 16 and compresses or discharge.
Transmission mechanism in Fig. 1 comprises motor 5, drive sprocket 6 and driven sprocket 7, and chain 13, strainer etc.The output shaft of its motor 5 is provided with drive sprocket 6, the rotating shaft of friction roller 8 is provided with driven sprocket 7, drive sprocket 5 and driven sprocket 7 are in transmission connection by chain 13.Strainer is hinged with tensioning pull bar 10 at shell 2 inwall, and be connected with spring 12, and the end of tensioning pull bar 10 is provided with regulating wheel 11.
In addition, as seen from Figure 1, be hinged with fork 14 in shell 2 upper inside, the rotating shaft 15 of described friction roller 8 is arranged on fork 14 end.Thus under strainer effect, fork 14 has certain pressure to center from start to finish, force friction pulley 8 to be close to the both sides of extension ladder 4, no matter how extension ladder every section width changes, and not only can guarantee frictional property, and can have certain pressure to resilient key.The one or both sides of extension ladder 4 can arrange rubbing surface 18, so that the frictional force between increasing friction roller.
