[0049] The adjustable supporting device according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0050] The adjustable supporting device according to the embodiment of the present invention includes a base 10 , a top seat 20 , a central hinge assembly 30 , a sliding block 40 and an adjusting assembly 50 .

[0051] Specifically, a cylindrical seat 12 with a hollow structure protruding upward is provided in the middle of the bottom plate 11 of the base 10; the top surface of the top plate 21 of the top seat 20 is a plane, and a spherical seat 22 with a hollow structure protruding downward is provided in the middle of the side opposite to the top surface; one end of the central hinge assembly 30 is formed as a ball head body 31, and the ball head body 31 is hingedly connected to the spherical seat 22; the other end is formed as a sleeve 32, which is embedded in the cylindrical seat 12 and can move up and down relative to the cylindrical seat 12; the slider 40 is placed on the base 10 and supports the top seat 20; the four sliders 40 are hinged with the center hinge The components 30 are arranged horizontally around the center; the slider 40 has a first contact surface 41 and a second contact surface 42 that can respectively abut the top seat 20 and the base 10; the extension surfaces of the first contact surface 41 and the second contact surface 42 can intersect to form a conical section, and one end of the intersection line is close to the central hinge component 30; the adjustment component 50 horizontally passes through the slider 40 and is connected to the central hinge component 30, and the adjustment component 50 can adjust the distance between the slider 40 and the central hinge component 30; wherein each slider 40 can be individually adjusted by the adjustment component 50.

[0052] In other words, the adjustable support device according to the embodiment of the present invention is mainly composed of a base 10, a top base 20, a central hinge assembly 30, a slider 40 and an adjustment assembly 50. Figure 1 As shown, a cylindrical seat 12 with a hollow structure protruding upward is provided in the middle of the bottom plate 11 of the base 10. The bottom plate 11 and the cylindrical seat 12 are preferably made of steel with high strength and low cost. The bottom plate 11 and the cylindrical seat 12 can be made as a whole by hot forging or connected by welding.

[0053] The top plate 21 of the top seat 20 is a plane surface, which is used for lifting / supporting the structure. A spherical seat 22 with a hollow structure protruding downward is provided in the middle of the side opposite to the top surface. The top 20 and the spherical seat 22 can be made of hot forging as a whole, or can be connected by welding. Figure 8As shown, a spherical cavity is formed inside the spherical seat 22. The top surface of the top seat 20 serves as a pressure-bearing surface for contacting and pushing into the structure 60, that is, the supported object.

[0054] The central hinge assembly 30 is arranged vertically, and one end of the central hinge assembly 30 is formed into a ball head body 31, which is hingedly connected to the spherical seat 22, so that the spherical seat 22 and the ball head body 31 can rotate in all directions; the other end of the central hinge assembly 30 is formed into a sleeve 32, which is embedded in the cylindrical seat 12 and can move up and down relative to the cylindrical seat 12. Therefore, the central hinge assembly 30 is restricted by the cylindrical seat 12, so that the central hinge assembly cannot move in the horizontal direction and can only move up and down in the vertical direction. Lubricating oil can be applied to the spherical seat 22 and the cylindrical seat 12 to reduce the friction of the movement of the central hinge assembly.

[0055] The slider 40 is placed on the base 10 and supports the top seat 20; there are four sliders 40, and the four sliders 40 have the same size and structure. The four sliders 40 are horizontally arranged around the central hinge assembly 30 with the central hinge assembly 30 as the center; the slider 40 has a first contact surface 41 and a second contact surface 42 that can abut against the top seat 20 and the base 10 respectively, that is, the first contact surface 41 of the slider 40 abuts against the top seat 20, and the second contact surface 42 of the slider 40 abuts against the base 10; the top seat 20 is supported by the first contact surfaces 41 of the four sliders 40. The extended surfaces of the first contact surface 41 and the second contact surface 42 can intersect to form a conical section, and one end of the intersection line is close to the central hinge assembly 30, that is, the cross-section of the slider 40 is similar to a trapezoidal section, wherein the two oblique sides form the first contact surface 41 and the second contact surface 42, and respectively abut against the top seat 20 and the base 10, and the short side of the trapezoid is close to the central hinge assembly 30; in this way, the first contact surfaces 41 of the four sliders 40 form a support for the top seat 20, and when the slider 40 approaches the central hinge assembly 30, as the abutment surface between the first contact surface 41 and the top seat 20 moves up along the first contact surface 41, the top seat 20 rises accordingly; when the slider 40 moves away from the central hinge assembly 30, as the abutment surface between the first contact surface 41 and the top seat 20 moves down along the first contact surface 41, the top seat 20 lowers accordingly.

[0056] The adjustment component 50 is arranged horizontally, passes through the slider 40 and is connected to the central hinge component 30, preferably connected by a hinge. The adjustment component 50 can adjust the distance between the slider 40 and the central hinge component 30. The adjustment component 50 can be one, and the adjustment function of the four sliders 40 can be realized through one adjustment component 50. The adjustment component 50 can also be four, corresponding to the sliders 40 one by one. The present invention preferably has four adjustment components 50, and the distance between the slider 40 and the central hinge component 30 can be adjusted by the four adjustment components 50. When the four sliders 40 are close to the central hinge component 30, as the first contact surface 41 and the contact surface of the top seat 20 move up along the first contact surface 41, the top seat 20 rises accordingly; when the four sliders 40 are away from the central hinge component 30, as the first contact surface 41 and the contact surface of the top seat 20 move down along the first contact surface 41, the top seat 20 lowers accordingly. In addition, each slider 40 can be adjusted individually by the adjustment component 50. The adjustment component 50 adjusts a single slider 40 to achieve fine adjustment of the horizontality of the top seat 20.

[0057] According to the adjustable support device of the embodiment of the present invention, the central hinge assembly 30 is used as the force-bearing core, which can slide freely up and down in the cylindrical seat 12. Restricted by the cylindrical seat 12, the central hinge assembly 30 cannot be displaced laterally to avoid the displacement of the top seat 20, and can only move up and down to drive the top seat 20 to rise and fall. At the same time, the ball head body 31 of the central hinge assembly 30 is installed in the ball seat 22 of the top seat 20, so that the top seat 20 can rotate around the ball head body 31, and the fine adjustment of the horizontality of the top seat 20 can be achieved while achieving height lifting and lowering.

[0058] Therefore, according to the adjustable support device of the present invention, the top seat 20 can rotate in all directions around the central hinge assembly 30, and the adjustment assembly 50 can adjust the distance between the four sliders 40 and the central hinge assembly 30. By adjusting the central hinge assembly 30 and the slider 40, the lifting and lowering of the top seat 20 is controlled, thereby realizing the adjustment of the height of the adjustable support device, and by adjusting the individual positions of the four sliders 40, the height adjustment of the top seat 20 in different directions is controlled, thereby realizing the fine adjustment of the horizontality of the top seat 20. The adjustable support device of the present invention is simple to operate, and can realize the fine adjustment of the horizontality while realizing the height adjustment, so that the structure 60 (the supported object) is evenly stressed, stress concentration is avoided to the greatest extent, deformation and damage of the structure 60 (the supported object) are reduced, and it can be applied to a variety of occasions.

[0059] According to one embodiment of the present invention, the adjustment assembly 50 includes: an adjustment screw 51, a connecting ear plate 52 and an adjustment nut 53, one end of the adjustment screw 51 is fixedly connected to the connecting ear plate 52, the connecting ear plate 52 is connected to the central hinge assembly 30, and the adjustment nut 53 is arranged at the other end of the adjustment screw 51 and abuts against the slider 40.

[0060] In other words, the adjustment assembly 50 is composed of an adjustment screw 51, a connecting lug 52 and an adjustment nut 53, see Fig.14 ,in, Fig.14 It is an exploded view of the adjustment component 50 according to the embodiment of the adjustable support device of the present invention. One end of the adjustment screw 51 is fixedly connected to the connecting ear plate 52, and the material thereof is threaded steel, preferably a trapezoidal thread high-strength fine-rolled threaded steel with a grade of PSB500 or above. The connecting ear plate 52 is connected to the central hinge assembly 30, preferably by a hinge connection. The connecting ear plate 52 is preferably made of 40cr material. The adjustment nut 53 is arranged at the other end of the adjustment screw 51 and abuts against the slider 40, and the slider 40 is located between the adjustment nut 53 and the connecting ear plate 52. The adjustment screw 51 passes through the slider 40 and is hingedly connected to the central hinge assembly 30, so that the slider 40 connected to the adjustment screw 51 has an adjustment function of rotating up and down with the hinge point of the adjustment assembly 50 and the central hinge assembly 30 as the center, so as to adapt to the lifting and lowering of the central hinge assembly 30.

[0061] The slider 40 is pushed closer to the central hinge assembly 30 by rotating the adjusting nut 53. As the abutment surface between the first contact surface 41 and the top seat 20 moves upward along the first contact surface 41, the top seat 20 rises accordingly. When the adjusting nut 53 is rotated in the opposite direction, the top seat 20 generates a force on the slider 40 away from the central hinge assembly 30 through the first contact surface 41 under the action of the gravity of the structure 60, so that the slider 40 continues to abut the adjusting nut 53. As the adjusting nut 53 rotates and moves, the slider 40 also moves accordingly. At this time, the abutment surface between the first contact surface 41 and the top seat 20 moves downward along the first contact surface 41, and the top seat 20 is lowered accordingly.

[0062] Therefore, according to the adjustable supporting device of the present invention, when supporting the structure 60, the top seat 20 generates a driving force on the slider 40 under the action of the gravity of the structure 60, and the self-locking function of the adjusting screw 51 and the adjusting nut 53 is used to prevent the slider 40 from moving, thereby forming a jack-like structure as a whole, which has a high load-bearing capacity and is safe and reliable.

[0063] According to one embodiment of the present invention, the adjustment assembly 50 also includes a spring 54, and a spring baffle 55 is provided at one end of the adjustment screw 51 close to the connecting ear plate 52. The spring 54 is passed through the adjustment screw 51, and one end of the spring 54 abuts against the spring baffle 55, and the other end abuts against the slider 40.

[0064] That is, a spring 54 is arranged between the slider 40 and the connecting ear plate 52, and the spring 54 is inserted into the adjusting screw 51. One end of the spring 54 abuts against the spring baffle 55, and the other end abuts against the slider 40. The spring 54 can freely shuttle along the adjusting screw 51, and the spring 54 is in a compressed state under normal conditions. When it is necessary to adjust the top seat 20 to rise, the adjusting nut 53 is rotated to push the slider 40 close to the central hinge assembly 30, and the spring 54 continues to be compressed and deformed under the action of the slider; when it is necessary to adjust the top seat 20 to lower, the adjusting nut 53 is rotated in the opposite direction, and the slider 40 moves away from the central hinge assembly 30 as the adjusting nut 53 moves under the action of the gravity of the top seat 20 and the tension of the spring 54. By arranging the spring 54 between the slider 40 and the connecting ear plate 52, a pre-tightening force is provided for the slider 40, and when the top seat 20 is adjusted to lower, it is further facilitated for the slider 40 to move away from the central hinge assembly 30.

[0065] According to one embodiment of the present invention, the center hinge assembly 30 includes: a center hinge piston 33 and a center hinge base 34, one end of the center hinge piston 33 is provided with a ball head body 31, and the other end is embedded in the center hinge base 34; one end of the center hinge base 34 away from the center hinge piston 33 is embedded in the cylindrical seat 12, and the other end is provided with four ear plates 35 on the outer circumference, and the ear plates 35 are hinged to the adjustment assembly 50; the center hinge piston 33 can perform piston motion in the center hinge base 34.

[0066] In other words, the center hinge assembly 30 is composed of a center hinge piston 33 and a center hinge base 34. Fig.11 As shown, a ball head body 31 is provided at one end of the center hinge piston 33, and the ball head body 31 is hingedly connected to the spherical seat 22. The other end of the center hinge piston 33 is embedded in the center hinge base 34, and the center hinge piston 33 can perform piston movement in the center hinge base 34. The end of the center hinge base 34 away from the center hinge piston 33 is embedded in the cylindrical seat 12, and can perform piston movement in the cylindrical seat 12. Four ear plates 35 are provided on the outer circumference of the other end of the center hinge base 34, and the ear plates 35 are hingedly connected to the adjustment assembly 50. Specifically, the ear plates 35 are hingedly connected to the connecting ear plates 52 of the adjustment assembly 50. In order to ensure the strength requirements of the center hinge assembly 30, the center hinge piston 33 and the center hinge base 34 are preferably made of 40cr manganese steel.

[0067] Therefore, according to the adjustable support device of the present invention, the center hinge assembly 30 serves as the force-bearing core, and its center hinge piston 33 can move freely up and down in the center hinge base 34, and the center hinge base 34 can move freely up and down in the cylindrical seat 12, further increasing the telescopic stroke of the center hinge component 30 and the lifting height of the top seat 20 to adapt to the support adjustment needs of different occasions.

[0068] In some specific embodiments of the present invention, the slider 40 includes an end plate 43 and a slide side plate 44; the end plate 43 is vertically arranged, and the two slide side plates 44 are vertically and parallelly fixed on one side of the end plate 43 and arranged opposite to each other, and the two side edges of the slide side plate 44 form a first contact surface 41 and a second contact surface 42, and the adjustment component 50 passes through the middle hole 45 of the end plate 43.

[0069] In other words, Fig.12 As shown, the slider 40 is mainly composed of an end plate 43 and a slide side plate 44. The end plate 43 is vertically arranged, similar to the long side of a trapezoidal cross section. The two slide side plates 44 are vertically and parallelly fixed on one side of the end plate 43 and arranged oppositely. The slide side plates 44 are welded together with the end plate 43. The upper and lower sides of the two slide side plates 44 form a first contact surface 41 and a second contact surface 42, similar to the two hypotenuses of a trapezoidal cross section. The angle between the two hypotenuses of the slide side plates 44 and the end plate 43 is an acute angle, preferably an angle of 75°, so as to form a propping effect on the top seat 20 and the base 10 when sliding close to the central hinge assembly 30. A middle hole 45 is provided in the middle of the end plate 43, and the adjustment assembly 50 passes through the middle hole 45 of the end plate 43 to drive the slider 40 to move.

[0070] In some specific embodiments of the present invention, the slider 40 further includes a reinforcing partition 46 and a washer 47 . The reinforcing partition 46 connects two parallel slide side plates 44 ; the washer 47 is disposed at the hole 45 in the end plate 43 .

[0071] In other words, the reinforcing partition 46 connects the two parallel slide side plates 44, and the reinforcing partition 46 and the slide side plates 44 form a semi-enclosed space, which plays a reinforcing role and reserves a movable space for the adjusting screw 51. The washer 47 is arranged at the position of the hole 45 in the end plate 43, which plays a role in reinforcing the strength of the end plate 43 and relieving the wear of the end plate 43 caused by the long-term contact of the adjusting nut 53.

[0072] In some specific embodiments of the present invention, a first slide 23 is provided on the top seat 20 and extends from the central hinge assembly 30 to the surrounding areas along the plane of the top plate 21. The position of the first slide 23 corresponds to the position of the first contact surface 41 to form a sliding fit, and the inclination angle of the first slide 23 corresponds to the inclination angle of the first contact surface 41.

[0079] In other words, bolt holes 15 are provided on the bottom plate 11 of the base 10 and the top plate 21 of the top seat 20, for assembling two or more adjustable support seat devices to meet the occasion where the adjustment height is insufficient. When the adjustment height of one adjustable support device is insufficient to adjust and support the structure 60, two or more adjustable support devices can be used, and the multiple adjustable support devices can be stacked together and connected by bolts through the bolt holes 15 to meet the use requirements.

[0080] The steps for using the adjustable support device of the present invention are as follows:

[0081] refer to Fig.15 As shown, Fig.15 It is a schematic diagram of the preliminary lifting of a structure (supported object) according to an embodiment of the adjustable support device of the present invention. First, place the adjustable support device of the present invention under the structure 60, at which time the adjustable support device is in the minimum height state. Secondly, rotate the adjusting nuts 53 in four directions to push the slider 40 close to the central hinge assembly 30. At this time, the top seat 20 slowly rises under the push of the slider 40, and the central hinge assembly 30 also extends accordingly. Since the bottom of the structure 60 is a slanted force-bearing surface with a low left side and a high right side, when the left side of the bottom of the structure 60 first contacts the top surface of the top plate 21, a support gap 70 still exists on the right side of the bottom of the structure 60. At this time, stop adjusting the other three adjusting nuts 53 except the right side. Continue to rotate the right adjustment nut 53, and the right slider 40 continues to push the top plate 21 upward. At this time, the other three positions of the top plate 21 are not stressed. Under the condition of unidirectional force on the right side, the top plate 21 moves in a universal direction around the ball head 31, and the right side of the top plate 21 continues to rise, forming the right side of the top plate 21 tilted, until the right side of the top plate 21 is completely in contact with the right side of the structure 60, and the adjustment is completed. At this time, the top plate 21 is completely in contact with the bottom surface of the structure 60. After the adjustment is completed, Fig.16 shown.

[0082] According to the adjustable support device of the present invention, the top seat 20 can rotate in all directions around the central hinge assembly 30, and the adjustment assembly 50 can adjust the distance between the four sliders 40 and the central hinge assembly 30. By adjusting the central hinge assembly 30 and the sliders 40, the lifting and lowering of the top seat 20 is controlled, thereby realizing the adjustment of the height of the adjustable support device, and by adjusting the individual positions of the four sliders 40, the height adjustment of the top seat 20 at different positions is controlled, thereby realizing the fine adjustment of the horizontality of the top seat 20. The adjustable support device of the present invention is simple to operate, and can realize the fine adjustment of the horizontality while realizing the height adjustment, so that the structure 60 (the supported object) is evenly stressed, stress concentration is avoided to the greatest extent, deformation and damage of the structure 60 (the supported object) are reduced, and it can be applied to a variety of occasions.
