[0002] At present, a Chinese patent with publication number CN117904958A discloses a bridge height adjustment bearing, in which two wedge blocks are symmetrically arranged between an upper adjustment plate and a lower adjustment plate, and a plurality of groups of grooves are arranged on the lower adjustment plate. The bottom surfaces of the two wedge blocks are provided with ridges matching the grooves, and the ridges are slidably connected in the grooves. A slope matching the wedge blocks is arranged on one side of the upper adjustment plate facing the wedge blocks. Mounting plates are arranged on the ends of the two wedge blocks, and driving elements are arranged between the mounting plates arranged on the same side of the two wedge blocks, and the driving elements are used to push the wedge blocks to move on the lower adjustment plate.

[0003] This patent has a complex structure, and the driving element is a hydraulic rod, which poses a great risk of hydraulic oil leakage leading to jacking failure. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a tensile-resistant height-adjustable rubber bearing and a height adjustment method thereof, so as to achieve the purpose of vertical height adjustment of the rubber bearing.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a tensile-type height-adjustable rubber bearing, comprising a rubber bearing body, an upper mounting plate and a lower mounting plate, wherein the upper mounting plate and the lower mounting plate are respectively fixed to the two ends of the rubber bearing body, and further comprising a limit baffle and a fixing plate for fixing with the embedded part, wherein the limit baffle is fixedly connected with the fixing plate, a lower limit groove is provided on the fixing plate, the lower limit groove is slidably connected with a lower wedge block along its length direction, and an adjusting bolt is connected to the limit baffle;

[0006] After the adjusting bolt rotates and pushes the lower wedge block to move along the lower limit groove, the rubber support body is moved in a direction away from the fixing plate through the transmission assembly.

[0007] To implement the above technical solution, the adjusting bolt is rotated to move the lower wedge block along the lower limit groove, and the rubber bearing body is moved upward through the transmission assembly, so that the height position of the rubber bearing body can be adjusted to adapt to the situation that when the rubber bearing body is subjected to tension, the lower wedge block continues to move along the lower limit groove. The rubber bearing body is only subjected to force after the lower wedge block collides with the end of the lower limit groove. In addition, through the limiting effect of the lower limit groove, the lower wedge block cannot be separated from the lower limit groove, so that the rubber bearing body can be stably subjected to force, thereby having a vertical tensile resistance effect.

[0008] As a preferred solution of the present invention, the transmission assembly includes an upper wedge block, an upper inclined groove, a guide block and a stop bar, the upper wedge block is connected to the lower mounting plate, the upper inclined groove is opened on the lower wedge block, the guide block is fixedly connected to the upper wedge block and slidably connected in the upper inclined groove, and the stop bar is fixed on the inner wall of the upper inclined groove and is used to interfere with the guide block.

[0009] To implement the above technical solution, the adjusting bolt is rotated, and the lower wedge block moves along the length direction of the lower limit groove. At the same time, the guide block moves along the length direction of the upper inclined groove, so that the height position of the rubber bearing body can be adjusted. When receiving a vertical force, the guide block and the baffle bar interfere with each other to prevent the guide block from falling out of the upper inclined groove. At the same time, the lower wedge block cannot fall out of the lower limit groove, so that the rubber bearing body is subjected to a vertical force, which plays a tensile resistance role.

[0010] As a preferred solution of the present invention, an L-shaped portion is fixedly connected to the upper wedge-shaped block, and the edge of the lower mounting plate is fixed in the L-shaped portion.

[0011] To implement the above technical solution, when subjected to vertical pressure, the upper wedge block tends to move along the length direction of the upper inclined groove, so that the L-shaped portion exerts a force on the lower mounting plate in a direction close to the rubber bearing body, thereby achieving a compression-resistant effect.

[0012] As a preferred solution of the present invention, a connecting recessed hole is provided on the side wall of the lower wedge-shaped block, and the end of the adjusting bolt has a hemispherical portion, and the hemispherical portion abuts against the inner wall of the connecting recessed hole.

[0013] The above technical solution is implemented to reduce the friction between the lower wedge block and the adjusting bolt.

[0014] As a preferred solution of the present invention, the adjusting bolt includes a rotating section and a displacement section, the rotating section is rotatably connected to the limit baffle, the displacement section is used to interfere with the connecting recessed hole, and the rotating section rotates and translates the displacement section through the conduction component.

[0015] To implement the above technical solution, the rotating section is rotated, and the displacement section is translated through the conduction component to abut against the inner wall of the connecting recessed hole.

[0016] As a preferred solution of the present invention, the transmission component includes a first tooth plate, a second tooth plate, a fixed rod, a screw groove, a slider, a straight groove, and an elastic member. The first tooth plate is slidably connected to the rotating section, and the two ends of the elastic member are respectively connected to the first tooth plate and the rotating section. The rotating section drives the first tooth plate to rotate through a flat key, and the second tooth plate is rotatably connected to the limit baffle and meshes with the first tooth plate. The fixed rod is fixed to the second tooth plate, the screw groove is opened on the outer wall of the fixed rod, and the straight groove is opened on the limit baffle. The displacement section is sleeved on the fixed rod, one end of the slider is slidably connected to the screw groove, and the other end of the slider passes through the displacement section and is slidably connected to the straight groove.

[0017] To implement the above technical solution, the rotating section is rotated, the first tooth plate drives the second tooth plate to rotate, the second tooth plate drives the fixed rod to rotate, and the slider moves along the length direction of the straight groove through the transmission action of the screw groove. At the same time, the slider drives the displacement section to move, so that the displacement section contacts the inner wall of the connecting recessed hole, pushing the lower wedge block to move. As the lower wedge block moves and the rubber support body moves closer to the equipment, the pressure on the rubber support body increases until relative rotation occurs between the first tooth plate and the second tooth plate, thereby avoiding pressure damage to the rubber support body; when relative rotation occurs between the first tooth plate and the second tooth plate, the elastic force of the elastic member causes the first tooth plate and the second tooth plate to correspond again; and the self-locking property of the screw groove is used to achieve positioning of the displacement section.

[0018] As a preferred solution of the present invention, a limiting ring groove is provided on the second tooth plate, the limiting ring groove is coaxially arranged with the second tooth plate, a straight rod is fixedly connected to the limiting baffle plate, and the straight rod is placed in the limiting ring groove.

[0019] To implement the above technical solution, during the rotation of the second tooth plate, the straight rod abuts against the inner wall of the limiting ring groove, so that the second tooth plate and the fixed rod cannot move, and at the same time, the second tooth plate can rotate smoothly.

[0020] As a preferred solution of the present invention, a first gear ring is fixedly connected to the outer wall of the first gear plate, a support seat is fixedly connected to the limit baffle, a drive sleeve is threadedly connected to the support seat, a second gear ring meshing with the first gear ring is fixedly connected to the outer wall of the drive sleeve, a positioning groove is provided on the support seat, a clamping block is hinged on the positioning groove, a clamping plate is fixedly connected to the fixed plate, and the drive sleeve rotates and positions the clamping plate between the clamping block and the support seat through a linkage structure.

[0021] To implement the above technical solution, during the rotation of the first tooth plate, the driving sleeve is moved along its own axial direction through the meshing action of the first tooth ring and the second tooth ring, and the clamping plate is positioned between the clamping block and the support seat through the linkage structure to achieve auxiliary positioning between the limit baffle and the fixed plate.

[0022] As a preferred embodiment of the present invention, the linkage structure includes a linkage rod, a connecting block, a convex portion, and a linkage groove. The linkage groove is opened on the support seat, the linkage rod is slidably connected in the linkage groove and both ends of the linkage rod are slidably connected to the driving sleeve, the convex portion is fixed to the end of the clamping block and forms an L-shaped structure with the clamping block, the connecting block is fixed on the linkage rod and contacts the convex portion, and the support seat is fixedly connected with a spring sheet for contacting the clamping block.

[0023] To implement the above technical solution, the driving sleeve rotates and moves along its own axial direction, and the linkage rod moves along the length direction of the linkage groove, so that the connecting block contacts the convex portion, so that the clamping block is flipped and the clamping plate is clamped by the support seat and the clamping block, and the driving sleeve is positioned on the support seat through the self-locking property of the thread; when the driving sleeve rotates and moves away from the support seat, the pressure of the spring sheet can cause the clamping block to rotate, so that the clamping block and the clamping plate are separated.

DETAILED DESCRIPTION

[0041] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0042] A tensile-type height-adjustable rubber bearing comprises a rubber bearing body 1, an upper mounting plate 11 and a lower mounting plate 12; the upper mounting plate 11 and the lower mounting plate 12 are respectively fixed to the upper and lower ends of the rubber bearing body 1. The rubber bearing body 1 is located at the center of the upper mounting plate 11 and the lower mounting plate 12. The device is fixed above the upper mounting plate 11.

[0043] The limit baffle 2 is in the shape of a square frame, and the fixing plate 21 is located inside the limit baffle 2. The limit baffle 2 is welded to the fixing plate 21. The fixing plate 21 is located below the lower mounting plate 12, and the fixing plate 21 is fixedly connected to the embedded part. A lower limit groove 22 is provided on the fixing plate 21, and the cross section of the lower limit groove 22 is T-shaped. Two lower limit grooves 22 are provided on each side of the fixing plate 21, and the length direction of the lower limit groove 22 is parallel to the length direction of the side of the fixing plate 21.

[0044] The lower wedge block 23 is slidably connected to the lower limit groove 22 along the length direction of the lower limit groove 22. Since the cross section of the lower limit groove 22 is T-shaped, the lower wedge block 23 can be prevented from moving up and coming out of the lower limit groove 22. An adjusting bolt 3 is connected to the limit baffle 2.

[0045] The transmission assembly 4 includes an upper wedge block 41, an upper inclined groove 42, a guide block 43 and a stop bar 44. An L-shaped portion 45 is fixedly connected to the upper wedge block 41, and the edge of the lower mounting plate 12 is welded and fixed in the L-shaped portion 45. The upper inclined groove 42 is opened on the lower wedge block 23, and the height position of the upper inclined groove 42 is lower at one end close to the rubber support body 1, and the height position of the upper inclined groove 42 is higher at one end away from the rubber support body 1. The guide block 43 is fixedly connected to the lower end of the upper wedge block 41 and slidably connected in the upper inclined groove 42. The stop bar 44 is fixed on the inner wall of the upper inclined groove 42 and is used to interfere with the guide block 43 to prevent the guide block 43 from escaping from the upper inclined groove 42, so that the cross section of the upper inclined groove 42 is T-shaped.

[0046] Accordingly, when the lower wedge block 23 is moved along the lower limit groove 22 toward the rubber support body 1, the guide block 43 is moved along the length direction of the upper inclined groove 42, so that the rubber support body 1 is moved vertically upward. Applying a vertical downward pressure to the rubber support body 1 can make the rubber support body 1 move downward while the guide block 43 is moved along the length direction of the upper inclined groove 42, and the lower wedge block 23 is moved along the lower limit groove 22 away from the rubber support body 1. In this way, the height position of the rubber support body 1 can be adjusted, so that the rubber support body 1 can provide better support for the equipment.

[0047] A connecting recessed hole 46 is provided on the side wall of the lower wedge block 23, and the cross section of the connecting recessed hole 46 is semicircular. The end of the adjusting bolt 3 has a hemispherical portion 47, which abuts against the inner wall of the connecting recessed hole 46, and the adjusting bolt 3 is rotatably connected to the limit baffle 2.

[0048] The lower wedge block 23 is pushed toward the rubber support body 1 by adjusting the bolt 3, so as to adjust the height position of the rubber support body 1. When the rubber support body 1 is subjected to vertical downward pressure, the limiting effect of the lower wedge block 23 by adjusting the bolt 3 can make the rubber support body 1 have better support and buffering effect on the equipment. When the rubber support body 1 is subjected to vertical tension, the lower wedge block 23 contacts the end of the lower limiting groove 22, and then the L-shaped portion 45 and the upper wedge block 41 apply a lateral force to the lower mounting plate 12, and then the rubber support body 1 is stretched, thereby achieving a better vertical tensile resistance effect.

[0049] The adjusting bolt 3 includes a rotating section 31 and a displacement section 32. The rotating section 31 is rotatably connected to the limit baffle 2, and the rotating section 31 cannot move. The displacement section 32 is used to abut against the connecting recess 46, and has a hemispherical portion 47. The rotating section 31 rotates and causes the displacement section 32 to translate through the transmission component 5.

[0050] The transmission component 5 includes a first tooth plate 51, a second tooth plate 52, a fixing rod 53, a screw groove 54, a slider 55, a straight groove 56, and an elastic member 57. The first tooth plate 51 is slidably connected to the rotating section 31, and the first tooth plate 51 slides along the length direction of the rotating section 31. The rotating section 31 drives the first tooth plate 51 to rotate through a flat key. The first tooth plate 51 is coaxially arranged with the rotating section 31. The elastic member 57 is a spring, and the two ends of the elastic member 57 are respectively connected to the first tooth plate 51 and the rotating section 31, so as to exert a force on the first tooth plate 51 to move toward the end of the rotating section 31.

[0051] The second tooth plate 52 is rotatably connected to the limit baffle 2 and meshed with the first tooth plate 51, and the first tooth plate 51 is coaxially arranged with the second tooth plate 52. The fixing rod 53 is coaxially fixed to the second tooth plate 52, and the screw groove 54 is opened on the outer wall of the fixing rod 53. The straight groove 56 is opened on the limit baffle 2, and the length direction of the straight groove 56 is parallel to the axial direction of the fixing rod 53. The displacement section 32 is sleeved on the fixing rod 53, and the displacement section 32 is coaxially arranged with the fixing rod 53. The slider 55 moves from top to bottom, so that one end of the slider 55 is slidably connected to the screw groove 54, and the other end of the slider 55 passes through the displacement section 32 and is slidably connected to the straight groove 56.

[0052] Accordingly, when the rotating section 31 is rotated, the rotating section 31 drives the first tooth plate 51 to rotate, the first tooth plate 51 drives the second tooth plate 52 to rotate, and the second tooth plate 52 drives the fixing rod 53 to rotate. Through the conduction of the thread, the slider 55 moves along the length direction of the straight groove 56. At the same time, the slider 55 drives the displacement section 32 to move, so that the displacement section 32 pushes the lower wedge block 23 to move.

[0053] As the lower wedge block 23 moves, it will exert pressure on the rubber support body 1. As the equipment generates a reaction force on the rubber support body 1, as the first tooth plate 51 continues to rotate, the first tooth plate 51 and the second tooth plate 52 will be separated and misaligned, and then re-matched through the elastic force of the elastic member 57. This prevents the rubber support body 1 from being damaged.

[0054] A limiting annular groove 59 is provided on the second tooth plate 52 , and the limiting annular groove 59 is coaxially arranged with the second tooth plate 52 . A straight rod 58 is fixedly connected to the limiting baffle 2 , and the straight rod 58 is placed in the limiting annular groove 59 , so that the second tooth plate 52 cannot move.

[0055] A first gear ring 6 is fixedly connected to the outer wall of the first gear plate 51, and the first gear ring 6 is coaxially arranged with the first gear plate 51. A support seat 7 is fixedly connected to the inner wall of the limit stopper 2, and a drive sleeve 71 is threadedly connected to the outer wall of the support seat 7. A second gear ring 72 meshing with the first gear ring 6 is fixedly connected to the outer wall of the drive sleeve 71, and the second gear ring 72 is coaxially arranged with the drive sleeve 71. The teeth on the first gear ring 6 and the second gear ring 72 are both straight teeth and are parallel to the length direction of the flat key.

[0056] A strip-shaped positioning groove 81 is provided on the support seat 7, and two symmetrically arranged clamping blocks 82 are hinged on the positioning groove 81. A U-shaped clamping plate 83 is fixedly connected to the side wall of the fixed plate 21, and the driving sleeve 71 rotates and positions the clamping plate 83 between the clamping block 82 and the support seat 7 through the linkage structure 9.

[0057] The linkage structure 9 includes a linkage rod 91, a connection block 92, a convex portion 93, and a linkage groove 94. The linkage groove 94 is provided on the support seat 7, and the length direction of the linkage groove 94 is parallel to the axial direction of the drive sleeve 71. The linkage rod 91 is slidably connected to the linkage groove 94, and both ends of the linkage rod 91 are slidably connected to the drive sleeve 71. When the drive sleeve 71 is rotated, the linkage rod 91 can move along the length direction of the linkage groove 94.

[0058] The protrusion 93 is fixed to the end of the clamping block 82 and forms an L-shaped structure with the clamping block 82. The connecting block 92 is fixed to the linkage rod 91 and contacts the protrusion 93. The support seat 7 is fixedly connected with a spring sheet 95 for contacting the clamping block 82. The spring sheet 95 contacts one end of the clamping block 82 near the protrusion 93.

[0059] Accordingly, during the rotation of the rotating section 31, the lower wedge block 23 moves, and at the same time, the first gear ring 6 drives the second gear ring 72 to rotate, and the second gear ring 72 drives the driving sleeve 71 to rotate. During the movement of the driving sleeve 71 along the length direction of the support seat 7, the connecting block 92 and the convex portion 93 collide, causing the clamping block 82 to flip along the hinge, and the end of the clamping block 82 moves toward the direction close to the clamping plate 83, so that the clamping plate 83 is not easy to escape from the cavity between the clamping block 82 and the support seat 7. This improves the connection stability between the fixed plate 21 and the limit baffle 2, and is not easy to separate due to large vibrations.

[0060] As mentioned above, after the second tooth plate 52 stops rotating, the first tooth plate 51 continues to rotate, so that the first tooth ring 6 drives the second tooth ring 72 to continue rotating until the rotating sleeve is tightened and the first tooth plate 51 cannot rotate.

[0061] The present invention also discloses a method for adjusting the height of a tensile-resistant height-adjustable rubber support, comprising the following steps:

[0062] S1, fixing the upper and lower ends of the rubber support body 1 to the upper mounting plate 11 and the lower mounting plate 12 respectively;

[0063] S2, a lower limit groove 22 is formed on the fixed plate 21, and the lower wedge block 23 is slidably connected to the lower limit groove 22;

[0064] S3, the upper wedge block 41 is fixedly connected to the upper mounting plate 11, an upper inclined groove 42 is opened on the lower wedge block 23, and the upper wedge block 41 is slidably connected to the upper inclined groove 42;

[0065] S4, a connecting recessed hole 46 is opened on the lower wedge block 23, the limit baffle 2 is fixed to the outside of the fixing plate 21, the adjusting bolt 3 is threadedly connected to the limit baffle 2, and the end of the adjusting bolt 3 is connected to the connecting recessed hole 46;

[0066] S5. Connect the fixing plate 21 to the embedded parts, and connect the upper mounting plate 11 to the equipment.

[0067] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
