Embodiment Construction

[0005] In order to enable those skilled in the art to better understand the technical solution of the present invention, the accompanying drawings and specific implementation methods are combined below. for further clarification. The spherical support device of the present invention adopts a pair of wear-resistant steel balls 1 as supports, and the two balls are symmetrically installed on the ball seat. When the steel ball 1 is working, it can do universal rotation. The contact surface between the inner ball seat 4 and the wear-resistant steel ball 1 is laid with a fluorine backing plate 5. The wear-resistant steel ball 1 and the fluorine backing plate 5 form a friction pair, and oil is supplied by the oil cup 12. lubricating. Ball seat is made up of inner ball seat 4, outer ball seat 3, damping pad 6, gland 2, adjustment pad 8, felt 9, oil cup 12, screw 10, screw 11, ball seat base plate 7. The inner and outer ball seats are installed on the ball seat bottom plate 7 with sc...

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 afriction 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 lugboss 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 steelballs. 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 [0001] The invention relates to the field of mechanical support equipment, in particular to a spherical hydraulic support device. Background technique [0002] The hydraulic support frame is an important accessory equipment in the oil casing disassembly and assembly equipment. Its main function is to play a supporting role in the casing disassembly and assembly process. When the casing is disassembled, it has both axial movement and rotation. The working surface of the support frame The support method should meet the work requirements. The prior art generally adopts a roller shaft device, which cannot meet the requirements of both movement and rotation of the casing. Contents of the invention [0003] The object of the present invention is to provide a spherical support device, which adopts a pair of wear-resistant steel balls as supports, and can be used for universal rotation. The friction pair composed of the ball and the fluorine backing plate has the...
