Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Fig. 1 to a kind of small-sized heavy load jacking apparatus shown in Fig. 3, including pedestal 1, motor 17,4 mechanism of plane cam and Horizontal drive mechanism, motor 17,4 mechanism of plane cam and horizontal drive mechanism are respectively arranged on pedestal 1, are driven by motor 17 Horizontal drive mechanism connection is in rolling contact by the idler wheels 2 of two sides and 4 mechanism of plane cam and drives 4 mechanism liter of plane cam Drop.
The principle of small-sized heavy load jacking apparatus provided by the utility model is as follows:
Motor 17 drives horizontal drive mechanism to slide in the horizontal direction, simultaneously as the idler wheel 2 on horizontal drive mechanism It is in rolling contact and connect with planar cam mechanism, therefore, during horizontal drive mechanism slides in the horizontal direction, rolling can be passed through The lifting of 2 driving planar cam mechanism of wheel.
In order to which the rolling of idler wheel 2 connects plane cam in the supporting role of scissor link mechanism 3 and horizontal drive mechanism The lifting realized on vertical direction is touched down, 4 mechanism of plane cam includes scissor link mechanism 3 and plane cam 4, scissor connecting rod machine Structure 3 and plane cam 4 are symmetrically distributed in 1 two sides of pedestal, are fixedly connected between plane cam 4 by connecting plate 5, scissor connecting rod machine It is connected between structure 3 by several connecting shafts 6,3 bottom end of scissor link mechanism is hinged in the fixed plate 7 of 1 side of pedestal, cuts The fork 3 bottom other end of link mechanism is slidably located in the fixed plate 7 of 1 side of pedestal, and 3 top one end of scissor link mechanism is hinged On the plane cam 4 for being located at 1 side of pedestal, the 3 top other end of scissor link mechanism is slidably provided at 1 side of pedestal On plane cam 4, plane cam 4 includes a upwardly recessed groove 1, and the inner wall of groove 1 is equipped with sliding surface, plane cam 4 further include a horizontal support surface 10 for being lower than sliding surface, and plane cam 4 is with the horizontal movement and idler wheel 2 of idler wheel 2 in sliding surface It is supported and goes up and down by idler wheel 2 with the sliding in horizontal support surface 10.
In order to which the idler wheel 2 slided to horizontal direction limits, be equipped in the fixed plate 7 of 1 two sides of pedestal respectively with it is flat The adaptable groove 29 of face cam 4.
In order to realize the supporting role of scissor link mechanism 3 in the vertical direction to plane cam 4,1 two sides of pedestal are consolidated The sliding slot 1 for the 3 bottom other end of scissor link mechanism and the sliding of the top other end is equipped on fixed board 7, on plane cam 4 Equipped with the sliding slot 2 12 for the 3 bottom other end of scissor link mechanism and the sliding of the top other end.
In order to which the rolling for keeping idler wheel 2 smooth is divided into horizontal support surface 10, sliding surface includes a vertical plane and an inclined-plane, inclined-plane Junction between horizontal support surface 10 forms smooth transition slope.
In order to, in lowest order, idler wheel 2 is fixed in plane cam 4, the connection of vertical plane and inclined-plane in plane cam 4 Place forms smooth transition arc surface.
In order to drive the roll-sliding in level of idler wheel 2, horizontal drive mechanism includes the ball screw driven by motor 17 13, feed screw nut 14, nut seat 15 and a pair of idler wheel 2 for being movably fixed to 15 two sides of nut seat respectively, are movably fixed to rolling Feed screw nut 14 on ballscrew 13 is fixed with nut seat 15 outside.
In order to realize buffering and reset response to 4 vertical lifting of plane cam, horizontal drive mechanism further includes that will put down The spring 16 of 4 reset of face cam, one end of spring 16 are fixed in the fixed plate 7 of 1 side of pedestal, the other end of spring 16 It is fixed in 4 mechanism of plane cam.
In one embodiment of the utility model, motor 17 drives ball screw 13 to rotate, and feed screw nut 14 is pushed to do level Movement, the further idler wheel 2 for driving 14 top nut seat of feed screw nut, 15 two sides fixed move horizontally together, idler wheel 2 and position Square plane cam 4, which is always maintained at, thereon is in rolling contact connection, converts horizontal movement to the vertical movement of plane cam 4, The load-carrying of 4 top of plane cam is further jacked, the scissor link mechanism 3 positioned at 1 two sides of pedestal plays holding, prevents It is all around shaken after 4 heavy duty jacking of plane cam, maintains high-order heavy duty steady, while 14 machine of ball screw 13 and feed screw nut Structure combination plane cam 4 accurately controls rising height.When plane cam 4 is in the non-raising state of low level, only connect with idler wheel 2 Touching, idler wheel 2 are in the state that do not stress;When jacking, idler wheel 2 is moved horizontally, and reduces resistance and plane cam 4 by rolling friction Power is transmitted to plane cam 4 by contact, it is made to move vertically, further, the load of 4 top of jacking plane cam;Work as liter When height arrives extreme higher position, the flat contact face contact of idler wheel 2 and plane cam 4, guarantee ball screw 13 is only by tangential force, no By axial force, in addition, since ball screw 13 is without self-locking function, when idler wheel 2 is in the horizontal contact face position of plane cam 4, It is not required to motor 17 to work again, so that energy be no longer consumed while realizing holding jacking height.Existing either hydraulic lifting Mechanism or screw rod lifting body, require consumption electric energy etc. to maintain to jack loaded-up condition, the present invention then completely without, from And it can effectively improve energy utilization efficiency.
The advantage of the utility model is:
The utility model utilizes the advantage of plane cam structure Yu scissor structure simultaneously, in conjunction with conservation of energy superposition principle, Physical burden, while compact-sized microminiaturization are effectively increased, can effectively overcome the problems, such as various narrow spaces but load weight, together When have the high advantage of jacking positioning accuracy.According to " conservation of energy superposition principle " principle, be converted to vertically using horizontal movement Movement, i.e., kinetic energy is converted to gravitional force, according to function=power × work distance principle, by increasing distance so that power is effectively reduced Demand, so that bigger load can be jacked it is only necessary to 17 torsion of motor of very little.
Above are merely preferred embodiments of the utility model, it is not intended to limit the utility model, it is noted that for For those skilled in the art, without deviating from the technical principle of the utility model, if can also make Dry improvement and modification, such improvement and modification also should be regarded as the protection scope of the utility model.
