Abstract

The utility model relates to an electric screw type lifting device. The electric screw type lifting device is suitable for shipping the object with heavy weight in the less storey situations and being used in the parking lots, and replaces the existing electric drag rope elevator. The electric screw type lifting device is mainly composed of a control box, a drive gear set, screw columns, a screw opening, a fixed bearing, etc. The control box is a power source of the complete machine and is an electronic control system device. The lateral face of the top of the control box is a bottom disc which is made of the hard material and is used as a support body of the complete machine. A drive gear wheel and four rotation gear wheels on the central position of the upper surface of the control box are meshed and are used as a power driving system. The rotation gear wheels and the screw columns are fixed into an integral body, and drive the box body to slide from top to bottom when the otation gear wheels follow the screw columns to rotate. The box body is a frame form structure. The top and the bottom of the box body are penetrated on the four screw columns, and realize the conversion of the rotation and the slide through the screw opening. The box body can be safely and stably lifted from top to bottom. The utility model has novel structure, simple theory and easy preparation and installation.

Description

Electric screw formula jacking system

Technical field:

The utility model relates to a kind of low-rise building occasions such as commercial and residential building room and parking area that are applicable to and promotes the electric screw formula jacking system of goods, can be used as elevator and transports than parcel lifting floor.

Technical background:

Elevator has become that the floor gap that generally uses in the modern architecture house conveys goods and the jacking system of manpower, and particularly along with the increasing of skyscraper building, escalator is must obligato jacking system.In addition, building is intensive in the modern city, and ground space is more and more littler, and the underground parking area of setting up of some building lacks the space, gangway, need vehicle that jacking system will be to be deposited to promote or drop to suitable floor, this also needs to design the jacking system that is suitable for using.Existing elevator is fairly perfect from structure and performance each side, and end is got up, and also there are a little deficiencies in existing elevator aspect the big dead weight cargo transporting, and the one, because its structure is by steel wire tow line rolling pull-up or puts down that it draws gravity not to be easy to do greatly; The 2nd, existing this pulling structure relatively adapts to the multi-story structure of high level, and when transporting weight for the seldom several floors of having only of special use, because need increasing the building of top layer, the installation of pulling frame sets up special escalator, cause trouble to architectural design, and have building to forbid when high in planning, and have to sacrifice top uneasy elevator and realize the lifting purpose, arrive top, need be climbed up top again at the second top elevator down, this is very inconvenient.The purpose of this utility model mainly is the electric screw formula jacking system that to convey goods the lifting problem between each level in the low level building and design and produce a kind of special use in order to solve, particularly design and produce a kind of underground multistory car park be used for lift car or convey goods with the vertical lift device of electric power as propulsion source.

Summary of the invention:

In order to realize goal of the invention of the present utility model; this device comprises control box; driving gear; arm revolving gear; the chassis; casing; borded pile; hand steered sleeve; assembly such as fixed type bearing and screw-socket; the control box top end face center of bottom of device is shaped on the dynamical axis interlock in driving gear and the control box; place, driving gear four direction angle four arm revolving gears of symmetry peace system and driving gear interlock; arm revolving gear and four upright borded pile bottoms are connected; four borded piles are respectively through being formed on the casing of framed structure; eight screw-sockets on the following end face penetrate casing; the top of four borded piles is shaped on fixed type bearing respectively; fixed type bearing can adopt welding or prefabricated means to be fixed on the top board of building; be shaped on hand steered sleeve respectively in the casing and between four pairs of cooresponding screw-sockets; both can protect the spiral shell of column in the casing, and can make the interior bearing people of casing again as handrail.Control box is made box structure, and conventional power plant, transmission gear shift equipment, electric auto-control system etc. are equipped with in its inside, belong to the prior art scope.The principle of work of this device is: drive four arm revolving gears simultaneously and rotate with speed when the driven by motor driving gear in the control box rotates, promptly four borded piles rotate synchronously, because borded pile and screw-socket adopt the biting connecions transmission, thereby when four borded piles rotate synchronously, casing is along four upper and lower slips of borded pile, and can control the speed that casing slides up and down easily through the speed of control motor.The utility model novel structure, principle is simple, processing and preparing and assembling easy construction, and transport power is big, be specially adapted to the lifting transportation of big weight object, and because casing overlaps dangerous phenomenons such as can not occurring the unexpected whereabouts of casing on four crash-resistant rigidity borded piles all the time.

Description of drawings:

Fig. 1 is the structural principle scheme drawing of the utility model.

Specific embodiments:

During enforcement, this device all adopts the hard rigid metallic material to be processed into agent structure, complete machine comprises control box 1, driving gear 2, arm revolving gear 3, chassis 4, casing 5, borded pile 6, hand steered sleeve 7, parts such as fixed type bearing 8 and bottle screw 9, control box 1 adopts prior art to assemble as the power and the control mechanism of complete machine, control box 1 should be firm as the base of complete machine and has a corresponding space structure, its top end face adopts hard steel plate to be processed into as domain 4,4 centers, chassis are shaped on the dynamical axis interlock in rotating driving gear 2 and the control box 1,4 arm revolving gears 3 be formed on admittedly respectively four rigidity screw pillars borded pile 6 the bottom and with driving gear 2 interlocks, when rotating with assurance driving gear 2, four arm revolving gears 3 can rotate and drive four borded piles 6 synchronously and rotate synchronously, whole box body 5 pierces on four borded piles 6, be shaped on four pairs of screw-sockets 9 of the same race respectively at the correspondence place of penetrating of casing 5, screw-socket 9 both was formed on the casing 5 admittedly, and can guarantee when rotating with borded pile 6 that again casing 5 integral body slide up and down steadily with the synchronous rotation of borded pile 6; In force, the inside of casing 5 can open type, also the internal protection layer can be housed; When adopting open type; 6 sections hand steered sleeves 7 that are shaped on stainless steel material outward of borded pile in the casing 5; both played the effect of protection borded pile 6; can be the landing people again safety rail is provided; hand steered sleeve 7 does not rotate with the rotation of borded pile 6; and can in sleeve, place suitable lubricating oils; smooth and easy to guarantee the rotation between borded pile 6 and the screw-socket 9; and can play the effect of eliminating the metal friction noise; fixed type bearing 8 is made on the top of four borded piles 6 respectively admittedly; the connecting element of its fixed type bearing 8 can be by welding or in advance on building top transverse slat or crossbeam, to guarantee the upright stable and smooth rotation of four borded piles 6.
