Description of drawings
Fig. 1 is the vertical section structure schematic diagram of the utility model jacking apparatus.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of jacking apparatus.
With reference to Fig. 1, Fig. 1 is the vertical section structure schematic diagram of the utility model jacking apparatus.
In the present embodiment, a kind of jacking apparatus is provided, comprise that power take-off unit, two are threaded the inclined-plane support slipper of through hole, two lifting fore-sets, what the tapped through hole of described two inclined-plane support slippers was adaptive is socketed on the screw-thread drive shaft 2, these screw-thread drive shaft 2 one ends are connected on the power take-off unit, described two lifting fore-sets are corresponding with the inclined-plane of described two inclined-plane support slippers respectively, and described each lifting fore-set is installed in the lifting fore-set fixedly in the chute device; Described power take-off unit comprises worm speed reducer 1 and hand wheel 11, and is connected with described screw-thread drive shaft 2 respectively; Roller 10 is equipped with in end, described lifting fore-set bottom, and described roller 10 is corresponding with support slipper inclined-plane, inclined-plane.Certainly, energy-conservation in order to use in the present embodiment, also can two bearings 3 be installed at screw-thread drive shaft 2, so that screw-thread drive shaft 2 rotates is laborsaving.Principle of the present utility model is, power take-off unit drives screw-thread drive shaft 2 and rotates, be threaded on the screw-thread drive shaft 2, two adaptive being socketed on the screw-thread drive shaft 2 of inclined-plane support slipper that are threaded through hole, hand of spiral corresponding to the screw-thread drive shaft of support slipper position, two inclined-planes is adaptive, corresponding above the inclined-plane support slipper lifting fore-set arranged at each, on the end face of described lifting fore-set bottom a roller 10 is installed, simultaneously lifting fore-set is in the fixedly chute device 8 interior slips of lifting fore-set, when screw-thread drive shaft 2 rotates, because the existence of screw thread, two inclined-plane support slippers are along screw-thread drive shaft 2 horizontal slips, his direction of slip depends on the direction of the screw thread on the screw-thread drive shaft 2, the user can be according to the direction of the adaptive selection screw thread of the installation direction on inclined-plane, and the roller 10 that contacts with the inclined-plane support slipper can roll and drive the lifting of whole lifting fore-set accordingly, jacking apparatus of the present utility model so just can be realized jacking or decline, the lifting fore-set can stop at current location because of the setting of screw thread transmission in outage simultaneously, the situation such as can not sink suddenly occurs, the appearance accident, worm speed reducer 1 outputting power that uses electric power generally speaking, in the time of outage, can hand rotation hand wheel 11, carry out the jacking operation.Certainly, easy to use for jacking apparatus, can also return facilities be housed at two lifting fore-sets, generally we use adaptive spring 9 as the main restoring force device that resets.
In the above-described embodiments, described jacking apparatus also comprises two detection and localization switches that high-order detector switch 13 and low level detector switch 12 be housed corresponding with described two inclined-plane support slippers, the high-order detector switch 13 of the corresponding detection and localization switch of inclined-plane vertex of described inclined-plane support slipper, the low level detector switch 12 of the corresponding detection and localization switch of inclined-plane nadir of inclined-plane support slipper.When inclined plane slide block moves to high-order detector switch 13 or low level detector switch 12; the detection and localization switch is just given 1 one signals of worm speed reducer; this signal control the start and stop of worm speed reducer 1, like this can actv. protects the safe handling of this utility model.In the present embodiment, described two lifting fore-sets are respectively equipped with the mechanical stop limiter for restriction lifting fore-set range, described two mechanical elevating inhibiting device link with two detection and localization Ka Guan respectively, described detection and localization Ka Guan generally adopts the spacing means of inductance approach switch, convenient and easy the realization, can certainly use other sensor, such as rang sensor etc., the interlock mode has multiple, when detecting the lifting fore-set and exceed position range such as automatically controlled detection inhibiting device, transmitted signal stops worm speed reducer 1 action.When automatically controlled limit detection device is malfunctioning can not the detection position time; this moment, mechanical stop limiter was with the generation effect; utilize support slipper sway position, two inclined-planes spacing; on a support slipper left side, two inclined-planes or the right side when moving to the limit mechanical resistance increase simultaneously generation current overload; utilize the current over-load protector overload protection; stop to produce interlock to the worm speed reducer power supply, realize mechanical electric interlock location double insurance.
In above-mentioned example, the inclined-plane of described two inclined-plane support slippers high-end close, namely the right tilted surface support slipper 4 shown in the figure and left tilted surface support slipper 6.Certainly, in another embodiment, two inclined-plane support slippers can be that low side is relative, or high-end relative with low side, and the hand of spiral on the corresponding screw-thread drive shaft 2 and the drive connection between the inclined-plane support slipper are also adjusted accordingly.
In the above-described embodiments, described lifting fore-set is perpendicular to described screw-thread drive shaft 2, like this can so that the lifting fore-set with equal length, the height of lifting is maximum, simultaneously, also can be so that the fixing chute device 8 stressed minimums of lifting fore-set.
In the above-described embodiments, one bracing or strutting arrangement is installed between two inclined-plane support slippers on the described screw-thread drive shaft 2, i.e. intermediate strutting device among the figure 5, mainly be in order to play screw-thread drive shaft 2 spacing effects with fixing, screw-thread drive shaft 2 can be fixed in a straight line, keep the position of screw-thread drive shaft 2 not to be offset, so just guaranteed stable use of the present utility model.
In the above-described embodiments, back-up block 7 is equipped with respectively on the top of described two lifting fore-sets, and described two support respectively to tilt to two outsides, help like this to hold up columniform object.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
