Abstract
The invention relates to the field of mechanical support equipment and in particular relates to a spherical support device. A pair of wearable steel balls capable of rotating universally is used as a support piece in the device. A fluorine cushion plate is laid on the contact surface of an inner ball base and the wearable steel balls. The wearable steel balls and the fluorine cushion plate form a friction pair having the characteristics of low friction coefficient and rapid rotating and sliding. The ball base is composed of inner and outer ball bases, the fluorine cushion plate, a shock absorption pad, a pressure cover, an adjustable pad, a felt, an oil cup, a screw and a ball base bottom plate. The inner and outer ball bases are installed on the ball base bottom plate through the screw. The outer ball base is used for pressing the inner ball base on the lug boss of the ball base bottom plate through the fluorine cushion plate. A rubber shock absorption pad is arranged between the lug boss of the ball base bottom plate and the groove of the inner ball base. A clearance is between the outer plane of the groove of the inner ball base and the outer plane of the lug boss of the ball base bottom plate so as to ensure that the shock absorption pad plays a role. The felt is arranged at the flange of the pressure cover. The felt surface tightly resists the wearable steel balls. The pressure cover is fixed on the outer ball base by the screw through the adjustable pad. The adjustable pad is used for adjusting the pressure of the pressure cover which is applied to the wearable steel balls. The centre line of the ball base and the vertical centre line of the spherical support device form an included angle of 15 degrees so as to be advantageously for centring and stabilizing a sleeve in the event of being disassembled and assembled.
Description
Technical field
The present invention relates to the mechanical support apparatus field, relate in particular to a kind of spherical hydraulic support device.
Background technology
Hydraulic support frame is auxiliary device important in the petroleum casing pipe disassemblerassembler, and its major function is to play a supportive role in the sleeve pipe disassembly process, and existing moving axially during the sleeve pipe dismounting has again rotation, and the supporting way of bracing frame working face should satisfy job requirement.Prior art generally adopts roller device, can not satisfy simultaneously sleeve pipe and both move, the requirement of rotating again.
Summary of the invention
The purpose of this invention is to provide a kind of spherical support device, this device adopts a pair of abrasion-proof steel ball as support member, can do Universal rotary, the contact-making surface of interior ball seat and abrasion-proof steel ball lays the fluorine backing plate, and abrasion-proof steel ball and fluorine backing plate form friction pair and have the sliding fast characteristics of the little rotation of coefficient of friction.Ball seat is comprised of inside and outside ball seat, fluorine backing plate, beam, gland, adjusting pad, felt, lubricating cup, screw, ball seat base plate.Described inside and outside ball seat is arranged on the ball seat base plate with screw, outer ball seat is pressed in interior ball seat on ball seat base plate boss by the fluorine backing plate, place Rubber shock-absorbing pad between ball seat base plate boss and interior ball seat groove, interior ball seat groove outerplanar and ball seat base plate boss outerplanar leave the gap, play a role to guarantee beam.Described gland stop portion is equipped with felt, and the felt face is close to abrasion-proof steel ball, and gland is fixed on outer ball seat by adjusting pad with screw, and the effect of adjusting pad is to adjust the pressure that gland gives abrasion-proof steel ball.The center line of described ball seat becomes 15 ° of angles with the vertical center line of spherical support device, the centering of sleeve pipe and stable when being beneficial to dismounting.
Description of drawings
Accompanying drawing is a kind of structure chart of spherical support device
The specific embodiment
For making those skilled in the art better understand technical scheme of the present invention, below in conjunction with the drawings and specific embodiments.Be described further.Spherical support device of the present invention adopts a pair of abrasion-proof steel ball 1 as support member, two ball symmetries are arranged on ball seat, abrasion-proof steel ball 1 center line becomes 15 ° of angles with the spherical support device vertical center line, can do Universal rotary during abrasion-proof steel ball 1 work, interior ball seat 4 lays fluorine backing plate 5 with the contact-making surface of abrasion-proof steel ball 1, abrasion-proof steel ball 1 forms friction pair with fluorine backing plate 5, supplies oil lubrication by lubricating cup 12.Ball seat is comprised of the outer ball seat 3 of interior ball seat 4, beam 6, gland 2, adjusting pad 8, felt 9, lubricating cup 12, screw 10, screw 11, ball seat base plate 7.Described inside and outside ball seat is arranged on ball seat base plate 7 with screw 10, outer ball seat 3 is pressed in interior ball seat 4 on ball seat base plate 7 boss by fluorine backing plate 5, place Rubber shock-absorbing pad 6 between ball seat base plate 7 boss and interior ball seat 4 grooves, interior ball seat 4 groove outerplanars and ball seat base plate 7 boss outerplanars leave the gap, to guarantee that beam 6 plays a role.Described gland 2 stop portions are equipped with felt 9, and felt 9 faces are close to abrasion-proof steel ball 1, and gland 2 use screws 11 are fixed on outer ball seat 3 by adjusting pad 8, and the effect of adjusting pad 8 is to adjust the pressure that gland 2 gives abrasion-proof steel ball 1.
