Description
Technical field
The present invention relates to a kind of for ballast support or levelling device, particularly relate to a kind of device support mechanism.
Background technology
Lifting Equipment mainly applies to large treatment device, the lifting of component, assembling, maintenance and installation, with realize equipment in said process or component levelling, between equipment bay and ground, producing gap, to be beneficial to fork of forklift truck in place or arrange rolling body between equipment and ground.
Above Lifting Equipment many employings mechanical jack, hydraulic jack or hydraulic power unit in prior art, but mechanical jack and hydraulic jack realize uprightly comparatively bothering of respective axial direction in the vertical direction in prior art, on the screw thread that mechanical jack is exposed after adhesive dust, easily thread failure is caused under larger load, pressurization deposited by hydraulic power unit and stringing part-structure is complicated, equipment cost is high, be not easy to carrying, also there is seal failure in hydraulic power unit and hydraulic jack simultaneously, and the accuracy levelling to equipment and device security exist the defect of hidden danger.
Summary of the invention
In order to solve, the fault rate that in above-mentioned prior art, Lifting Equipment exists is high, device structure is complicated, be not easy to the problem installing or affect jacking precision, the invention provides a kind of device support mechanism.
For the problems referred to above, the present invention solves problem by the following technical programs: a kind of device support mechanism, comprise base and be fixed on the lifting unit for device support on base, described lifting unit comprises lifting handle, lifting pin and the negative thread seat in column, described negative thread seat is provided with the internal thread hole along its axis, lifting pin is provided with outside thread and multiple axial tooth, described axial tooth is uniform along lifting pin side, and the axis being parallel of the length direction of axial tooth and lifting pin, one end of described lifting handle is between any two axial tooths, outside thread on lifting pin becomes to be threaded with described internal thread hole, negative thread seat is fixedly connected with base, also seal ring is provided with between the upper end of described lifting pin and negative thread seat, the upper end of described lifting pin is also provided with the top cover that can rotate around lifting pin circumference.
Concrete, the lifting handle arranged is used for breaking top rising stem and rotates: apply compression effort by lifting handle to the side of axial tooth, lifting pin rotates around its axis, on outside thread on lifting pin and negative thread seat, the application force of negative thread forces lifting pin to rise or declines, the upper end of lifting pin is the present invention and the plane of action treating Lifting Equipment, namely the present invention regulates lifting pin relative to the position of equipment by traversing portion, is regulated the height of lifting pin by lifting handle; The seal ring arranged drops in the screw thread pair between negative thread seat and lifting pin for preventing dust or other impurity; The top cover arranged, for reducing the friction force of the present invention in the course of the work and between equipment, is namely achieved the above object by the friction of rolling of top cover and lifting pin.Further, the negative thread on preferred negative thread seat is the T-shaped screw thread with self-locking pitch, to increase load-carrying capacity of the present invention and to simplify operation of the present invention, can remove the power be applied on traversing handle when lifting pin arrives ultimate position.
Further technical scheme is:
Described lifting handle comprises drive sleeve and is set in the brake rod in drive sleeve, one end and the lifting pin of described drive sleeve are articulated and connected, and drive sleeve can be rotated around the circumference of lifting pin, one end end face that brake rod gos deep into drive sleeve is diagonal-cut joint, and the other end of brake rod protrudes relative to drive sleeve.
The drive sleeve arranged is convenient to the relative position of fixing lifting handle relative to lifting pin: namely make the interactional brake rod with axial tooth be positioned at lifting pin all the time in the radial direction, the diagonal-cut joint arranged makes the structural relation between lifting handle and axial tooth be ratchet structure, namely by regulate diagonal-cut joint towards, operating personal braking lifting handle carrys out back rotation by a small margin, can realize the directional rotating impelling lifting pin.
For ease of described diagonal-cut joint towards adjustment, making to complete diagonal-cut joint can automatically revert in the teeth groove between axial tooth towards the rear brake rod of adjustment at every turn, also spring cavity is provided with in described drive sleeve, retracing spring is provided with in spring cavity, described brake rod is also provided with boss, described retracing spring to be set on brake rod and to be in compressive state, retracing spring and being limited between spring cavity and boss.The retracing spring arranged forces brake rod towards an end motion of axial tooth.
One end that described brake rod is provided with diagonal-cut joint is also provided with two radial notchs, described radial notch lays respectively at otch upper side and the otch comparatively downside of diagonal-cut joint, and the distance on two radial notch distance diagonal-cut joint tops is less than the degree of depth of teeth groove between adjacent axial tooth, the width of brake rod is greater than the width of described teeth groove.The position of two radial notchs arranged and the setting of the width of brake rod are collided for the top and teeth groove preventing diagonal-cut joint, can prevent like this diagonal-cut joint generation plastic deformation affect diagonal-cut joint towards adjustment.
For ease of diagonal-cut joint towards fixing and diagonal-cut joint towards instruction, to improve the efficiency that breaking top rising stem rotates, the free end of described drive sleeve is also provided with draw-in groove, and described brake rod is also provided with two card articles relative to one end that drive sleeve is protruded.
Described base is also provided with at least two bolt of lower base holes.The bolt of lower base hole arranged is used for the fixing of base, with the use of holding-down bolt, is conducive to the stability that the present invention installs.
For making the present invention can for treating that Lifting Equipment provides more than strong point, more than one of the quantity of described lifting unit.
For preventing treating that Lifting Equipment is by landing in the present invention, also comprise the side block block be arranged on negative thread seat, and described side block block can rotate around the axis of negative thread seat.Side block block and equipment contacts side surfaces in use, the version that side block block can rotate around negative thread seat, makes the present invention be not limited to equipment and puts orientation relative to of the present invention.
The present invention compared with prior art, has following beneficial effect:
The lifting handle arranged is used for breaking top rising stem and rotates, namely the present invention regulates the height of lifting pin by lifting handle, like this, base is used for support top rising stem makes it be in vertical direction, the type of drive of pure mechanical structure form, this make the present invention not only load-carrying capacity strong, be easy to put, also there is the high feature of jacking precision simultaneously; The seal ring arranged drops in the screw thread pair between negative thread seat and lifting pin for preventing dust or other impurity, is conducive to ensureing service life of the present invention; The top cover arranged to make in working process of the present invention because friction force to rotate to lifting pin the resistance brought little, this makes finishing equipment support labor-saving of the present invention, efficiently.
