Abstract
The invention provides a supporting leg and a universal wheel for heavy equipment, which relate to the design and innovation of supporting and transporting components of the heavy equipment. A multi-ball type universal wheel is fabricated by evenly distributing a plurality of ball roller wheels on the same circumference of the same wheel disc; a spiral type supporting leg is arranged in the middle of the multi-ball type universal wheel; a layer of thick high-performance damping cushion is arranged above the multi-ball type universal wheel and is fixed under an equipment bracket by a plurality of symmetrically-distributed bolt washers. When extending out, the spiral type supporting leg replaces the multi-ball type universal wheel to play a role in supporting; and when the spiral type supporting leg retracts, the multi-ball type universal wheel restores the transporting function. The problems that the universal wheel has a large size, is easy to deform due to long-term stress, cannot adjust the height and the level of the equipment and the like are solved. The high-performance damping cushion can effectively absorb vibrations when the equipment runs, and can further reduce uneven stresses and vibrations of the roller wheels caused by uneven ground surface when the equipment is used for transportation. Thus the high-performance damping cushion is a caster wheel component with comparatively complete functions for the heave equipment.
Description
Affiliated technical field
The present invention relates to the design and the innovation of heavy wares supporting and transport section.
Background technology
At present, domestic and international quantity-produced industrial castor of specialized factory and universal caster wheel, as gauge member or general part, extensively be installed on hand barrow, furniture, seat and the roving middle-size and small-size medical facilities of palpus, the electromechanical appliance, bring great convenience for people's work, life and production.But, deal big for many volumes is heavy, and without the under-chassis bolt, less again mobile heavy wares but lacks a kind ofly based on supporting, can conveniently move caster wheel once in a while.Existing gauge member or general part castor based on transportation, obviously can not carry on a shoulder pole its important task: the one, bear static heavy load for a long time, castor easily produces permanent deformation; The 2nd, the anti-heavy load caster wheel size of energy is bigger than normal, very inapplicable; The 3rd, can not regulate height and level, be difficult to satisfy the installation and the operating needs of equipment.Along with the development of society, the use amount of heavy wares in all trades and professions constantly rises, and be if at the indoor heavy wares that moves once in a while, just remove to call large-scale lifting and transportation device, very uneconomical certainly, also inconvenient.So, for a kind of energy of heavy device design supports, the caster wheel that can roll is necessary.
Summary of the invention
The present invention organically combines both according to the principle and the screw rod rotating regulation type under-chassis structure commonly used of existing ball-type universal caster wheel, designs a kind of support foot and cardan wheel of heavy wares special use.
The present invention adopts following scheme to realize: many ball rollers are evenly distributed on the same circumference of same wheel disc, make many ball type universal wheel, a spiral type supporting leg is installed in the centre of many ball type universal wheel, on many ball type universal wheel, add the thick performance-oriented cushion blocking of one deck, with the bolt washer of several symmetrical distributions be fixed on equipment supporter below.When spiral type supporting leg is stretched out, substitute many ball type universal wheel and play a supportive role; During the spiral type supporting leg indentation, many ball type universal wheel are recovered transportation function.
Specialize in support with spiral type supporting leg, can prevent the long-term stress deformation of many ball type universal wheel, influence its rolling characteristics; And height and level that can conditioning equipment, satisfy the installation and the operating needs of equipment.Many ball type universal wheel can be reduced oad greatly, prevent to increase equipment volume; And the weight that can effectively decompose heavy wares, prevent self parts distortion and ground surface damage.Add performance-oriented cushion blocking between equipment and many ball type universal wheel, trembling when absorption equipment moves effectively at ordinary times more can be reduced the uneven and equipment vibrations of the roller stress that causes because of the ground injustice during transportation; Be the comparatively complete heavy wares of a kind of function castor parts.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
The present invention is combined by many ball type universal wheel A, spiral type supporting leg B, performance-oriented cushion blocking (12) and bolt washer (13), except that felt collar oil sealing (6) and cushion blocking (12), is metal parts; Every heavy wares uses quantity of the present invention at least more than three.
Many ball type universal wheel A is made up of wheel disc (3), small ball (4), ball roller (5), felt collar oil sealing (6), back-up ring (7) and screw (11).Many ball rollers (5) are rectangular distribution on the same circumference of same wheel disc (3), and quantity is 3～12, is used for sharing different weights of equipment; The top of every ball roller (5) the circle small ball (4) that all gathers, improving its rolling characteristics, but and any direction rotation, so be referred to as " many ball type universal wheel ".Wheel disc (3) is the hollow parts that profile is " protruding " sample, and the center is the big screw of dress supporting screw (1), is the two-layer stepped hole that size is slightly larger than clamp (9) and sole (10) below the screw greatly, it can be taken in the abdomen; The bottom surface is on the line of the center of circle of same diameter, uniform the blind hole identical and the screw hole of equivalent amount with ball roller (5) quantity, the limit mouth of blind hole all is processed with oil seal groove, with felt collar oil sealing (6), back-up ring (7) and screw (11), small ball (4) and ball roller (5) is encapsulated among the blind hole; On top and the plane that cushion blocking (12) contact, select the neutral gear between the blind hole of bottom surface, process the bolt hole of 2～6 symmetrical distributions, usefulness bolt washer (13) is connected with cushion blocking (12) with equipment supporter (14).Felt collar oil sealing (6) is attached to the surface of ball roller (5), can prevent that internally lubricating oil from oozing out, and external enwergy is prevented that dust from entering.Back-up ring (7) is corresponding with the shape of wheel disc (3) bottom surface, and uniform identical macropore and the aperture of quantity, big bore dia are less than ball roller (5), in case it comes off, aperture is fixed itself and wheel disc (3) with screw (11).
Spiral type supporting leg B is made up of supporting screw (1), jam nut (2), screw (8), clamp (9) and sole (10); Supporting screw (1) has an end of prismatic column to make progress, and is contained in the centre of wheel disc (3), drives its rotation with spanner, realizes up-and-down movement, when arriving the desired location, tightens jam nut (2) again from above; There is an end of circular groove downward, inserts two semicircle clamps (9), be connected with sole (10), damage ground when preventing supporting screw (1) rotation with the screw (8) of several symmetrical distributions.Spiral type supporting leg B does not directly contact with equipment supporter (14), and in the intersection of equipment supporter (14) with supporting screw (1) and jam nut (2), leaving can be for the crack, work hole of spanner activity, so that give full play to the shock-absorbing function of cushion blocking (12).
Cushion blocking (12) is a polymer composite, and hardness is: (45～65) Shao Shi A, and tensile strength at break is: (10～15) MPa, thickness is: (1～3) centimetre, to satisfy the performance requriements of damping and resistance to deformation.
