Abstract

The invention discloses an electric jacking device which comprises a base with wheels, wherein a motor and a machine frame are mounted above the base; the motor is in matching transmission with a gear mechanism arranged at the upper part of the machine frame through a reducer and a chain wheel mechanism in sequence; the gear mechanism is used for driving a gear rack in the machine frame to move up and down; one side of the gear rack is fixedly connected with a lifting frame arranged at the upper part of the machine frame; and the lifting frame can slide up and down along a chute on the inner side of the machine frame. Due to the design principle of chain transmission and a gear rack mechanism, the electric jacking device is movable, small in size, convenient and reliable, can be operated in a room or outdoors, reduces the labor intensity and improves the working efficiency.

Description

A kind of electronic jacking apparatus

?

Technical field

The present invention relates to the equipment of a kind of midget plant, pipeline installation application, belong to the Architectural Equipment technical field.

?

Background technology

At present, for the installation of some small-sized pipe fittings, mainly rely on manpower or use jack to promote pipe fitting, labour intensity is big, and efficient is low, and large lifting equipment can't be implemented because limit in the place.

Summary of the invention

It is a kind of removable the present invention seeks to provide to the defective that prior art exists, and volume is little, can be in the room or the electronic jacking apparatus of field work.

The present invention adopts following technical scheme for realizing above-mentioned purpose: a kind of electronic jacking apparatus, comprise the base of being with wheel, and said base top is equipped with motor and frame; Said motor cooperates transmission through retarder, chain-wheel mechanism and the gear mechanism that is arranged on said upper rack successively; Said gear mechanism driving is arranged on said frame in-to-in tooth bar and moves up and down, and said tooth bar one side is captiveed joint with the crane that is arranged on said upper rack; Said crane can be along the inboard chute slippage up and down of said frame.

Further, said gear mechanism comprises through big gear wheel, minor sprocket and the tooth clutch of axle mounting on said frame; Said minor sprocket cooperates installation through chain with hinge wheel on being arranged on motor; Said big gear wheel is installed in said frame inside and cooperates installation with said tooth bar.

Further, on one side said tooth clutch is welded on the axle, another side is installed on the minor sprocket, with minor sprocket together sky be enclosed within on the said axle, can slide along axle.

Preferably, said clamping mechanism is made up of carriage and spiral push rod.

Preferably, also comprise rack-mounted electric machine controller.

Beneficial effect of the present invention: this device utilizes chain-driving and pinion and rack principle of design, and removable, volume is little, can be in the room or field work, and convenient and reliable, reduce labour intensity, improved work efficiency.

Description of drawings

Fig. 1 front view structural representation of the present invention;

Fig. 2 left view structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:

Like Fig. 1, shown in Figure 2, be a kind of electronic jacking apparatus, base 7 belows are equipped with wheel 8, and base 7 tops are equipped with frame 6, and motor and retarder 9 are installed between base 7 and the frame 6 and are fixed on the base 7.Gear 4 is equipped with on frame 6 tops, and gear 4 is installed on the axle 14 with the tooth clutch 15, the minor sprocket 13 that are installed in frame 6 one sides jointly.This axle 14 is installed on the frame 6, and hinge wheel 10 is installed in motor and retarder 9 ends, and minor sprocket 13 is connected through chain 11 with hinge wheel 10; Crane 3 is contained in frame 6 tops; Tooth bar 5 is equipped with in crane 3 one inboards, and tooth bar 5 is meshed with gear 4, and gear body partly has u type hole; Axle 14 passes u type hole, is beneficial to crane 3 and goes up and down with tooth bar 5.Carriage 2 and spiral push rod 1 are equipped with in crane 3 tops.Said tooth clutch 15 is welded on the axle 14 on one side, and another side is installed on the minor sprocket 13, and with minor sprocket 13 together sky be enclosed within on the said axle 14, can slide along axle; Realize the closed of tooth clutch 15 and separate, with minor sprocket 13 mating parts be castellated shaft.Electric machine controller 12 is installed on the frame 6, the forward and backward of control motor.

In use, be placed on pipe fitting or small-sized parts on the carriage 2 earlier, adjust two spiral push rods 1 then simultaneously, workpiece is fixed on the carriage 2; Make power-transfer clutch 15 be in released state, press electric machine controller 12 then, motor and retarder 9 rotate, and rotate thereby drive hinge wheel 10; Hinge wheel 10 drives minor sprocket 13 and rotates through sprocket wheel 11, and minor sprocket 13 rotates with gear 4 coaxial 14, gear 4 and tooth bar 5 engagements; Tooth bar 5 drives crane 3 and goes up and down, thereby workpiece is promoted or landing, after equal altitudes is adjusted; Disable motor controller 11, closed tooth clutch 15 is fixed on the setting height workpiece.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
