Description

Technical Field

[0001] The invention relates to the technical field of height-adjustable supports, in particular to a height-adjustable support with adjustable anchoring thickness. Background Art

[0002] At present, the common height adjustment schemes at home and abroad include four methods: pad height adjustment, spiral height adjustment, wedge height adjustment and injection filling body height adjustment. The spiral height adjustment structure bears the load through the threaded pair, which is not suitable for occasions with high bearing capacity requirements; the bolts that push the wedge in the wedge height adjustment are subject to large forces, and the wedge inclination cannot be too large, so the height adjustment amount is limited; the height adjustment operation of the filling body is complicated, and the filling body solidification time is long; the pad height adjustment method is currently the most widely used and simplest height adjustment method. The pad height adjustment support is adjusted by adding a height adjustment pad between the support and the bottom of the beam. Since the support anchor is connected to the support upper plate, the height adjustment pad and the pre-buried sleeve at the bottom of the beam through the upper bolt, the bolts anchoring the support and the beam body need to increase the design length to meet the maximum height adjustment requirements of the support. When the length of the anchor bolt on the support increases, the design height of the support needs to be increased to meet the anchor bolt installation space. Therefore, the weight of the support increases significantly and the economy is poor. In recent years, a retractable screw height adjustment structure has also appeared, but this structure uses a full-thread connection method. The screw telescopic operation during the height adjustment process is complicated and the height adjustment speed is slow. In addition, since the screw thread bears the horizontal load of the support, the thread is easily compressed and deformed, causing telescopic obstacles when adjusting the height again. It is necessary to develop a more convenient and reliable large-adjustment support to meet various height adjustment requirements. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an adjustable height bearing with adjustable anchoring thickness, which solves the problem that the existing general height-adjustable bearing has different bearing heights due to different height adjustment amounts and poor economy, and solves the problem that the existing screw telescopic anchor scheduling bearing is inconvenient to operate and the height adjustment failure caused by thread deformation due to stress. The bearing meets the requirements of reliable function, easy operation, wide range of height adjustment and good economy.

[0004] In order to achieve the above technical purpose, the adopted technical solution is: an adjustable height support with adjustable anchor thickness, comprising a support body, an adjustable height anchor bolt and a common anchor bolt;

[0005] The support body is composed of a beam bottom embedded plate, an upper seat plate, a middle seat plate and a lower seat plate symmetrically arranged along the center line. The lower seat plate is composed of a lower crown body located in the center and a lower flat plate outside the lower crown body. The lower flat plate and the lower crown body are arranged as one body. Lower anchor holes for installing ordinary anchor bolts are provided at the four feet of the lower flat plate. A concave spherical surface is provided on the upper surface of the lower crown body. A middle seat plate is installed above the lower crown body. The lower surface of the middle seat plate is a convex spherical surface matching the concave spherical surface. The upper surface of the middle seat plate is a plane. An upper seat plate is installed above the middle seat plate. It is composed of an upper plate located in the middle and a limit plate integrally arranged with the upper plate. The two limit plates are respectively not in contact with the middle seat plate and are vertically arranged on the outer longitudinal or transverse sides of the lower crown body. A guide friction pair is arranged between the limit plate and the lower crown body. The upper and lower surfaces of the upper plate are both planes. Two upper anchor holes for installing height-adjustable anchor bolts are respectively arranged on the transverse side edges of the upper plate. A beam bottom embedded plate is fitted on the upper surface of the upper plate. The beam bottom embedded plate is provided with mounting holes corresponding to the upper anchor plates for the height-adjustable anchor bolts to pass through.

[0006] The height-adjustable anchor bolt comprises a sleeve, an anchor rod, an adjusting bolt, a deformable plate and a nut. The lower end of the sleeve is installed in the mounting hole and is pressed against the upper surface of the upper seat plate. The sleeve is provided with a deformable plate and one end of the anchor rod that match the clearance of the inner hole of the sleeve. The other end of the anchor rod passes through the matching upper anchor hole and is tightened and fixed to the upper surface of the upper plate by the nut. A through hole is provided in the center of the anchor rod, and the through hole matches the clearance of the adjusting bolt. The adjusting bolt is inserted from the lower end of the anchor rod and extends out from the other end and is threadedly connected to the deformable plate. A protruding part on the lower surface of the deformable plate is a convex column, and a slot is provided on the upper surface of the anchor rod. The convex column is arranged in the slot. The deformable plate is pressed or left on the upper surface of the anchor rod by rotating the adjusting bolt, and the deformable plate is deformed and pressed or moved away from the inner wall of the sleeve to achieve compression, fixation or contraction and relaxation.

[0007] The deformation plate is composed of an upper fixed plate and a lower elastic block, and the elastic block is arranged close to the inner hole surface of the sleeve.

[0008] One or more pairs of parallel planes are arranged on the side surface of the anchor rod below the nut.

[0009] The lower end of the sleeve is provided with a stepped outer circle, and the stepped surface is respectively arranged on the upper surface of the upper flat plate and the upper surface of the beam bottom embedded plate.

[0010] The beneficial effects of the present invention are:

[0011] 1) The height-adjustable support structure of the present invention is applicable to the height-adjustable support with a large height-adjustable amount. The support height does not change with the height-adjustable amount. This setting does not affect other functions of the support structure and has good economy and cost-effectiveness.

[0012] 2) The height adjustment operation of the height-adjustable support described in the present invention is simple and convenient. Tightening and loosening can be achieved quickly by simply turning the adjustment bolt, and the axial position can be adjusted and fixed, which greatly improves the operating efficiency of the support height adjustment and has the advantages of high height adjustment frequency, short cycle and low cost.

[0013] 3) The height-adjustable support of the present invention transmits the horizontal force of the support through the outer cylindrical surface of the anchor rod, which makes the force more safe and reliable, avoids the adverse effect of thread extrusion and deformation caused by the use of a threaded structure to transmit force in contact with the sleeve or the support, resulting in the inability to rotate the thread, and also avoids the risk of anchor failure caused by stress concentration caused by the threaded structure.

[0021] The support body 1 is composed of a beam bottom embedded plate 101, an upper seat plate 102, a middle seat plate 103 and a lower seat plate 104 which are symmetrically arranged along the center line. The lower seat plate 104 is composed of a lower crown body 104-1 located in the center and a lower flat plate 104-2 outside the lower crown body 104-1. The lower flat plate 104-2 and the lower crown body 104-1 are integrally arranged. The size of the lower flat plate 104-2 is smaller than that of the upper seat plate 102. The four feet of the lower flat plate 104-2 are provided with lower anchor holes for installing ordinary anchor bolts 3. Ordinary The anchor bolt passes through the lower anchor hole and is fixedly connected to the bridge pier. The upper surface of the lower crown body 104-1 is provided with a concave spherical surface. A middle seat plate 103 is installed above the lower crown body 104-1. The lower surface of the middle seat plate 103 is a convex spherical surface that matches the concave spherical surface. The concave spherical surface and the convex spherical surface match to realize the rotation of the support, and a rotating friction pair is provided between the two. The upper surface of the middle seat plate 103 is a plane. An upper seat plate 102 is installed above the middle seat plate 103. The upper seat plate 102 consists of an upper flat plate 102-1 located in the middle and a convex spherical surface that matches the upper The plate 102-1 is composed of a limit plate 102-2 which is integrally arranged. The two limit plates 102-2 are respectively not in contact with the middle seat plate and are vertically arranged on the outer longitudinal or transverse sides of the lower crown body 104-1. The support can slide in the transverse bridge direction or the longitudinal bridge direction. A guide friction pair is arranged between the limit plate 102-2 and the lower crown body 104-1. The upper and lower surfaces of the upper plate 102-1 are both flat. Two upper anchor holes for installing height-adjustable anchor bolts 2 are respectively arranged on the transverse side edges of the upper plate 102-1. The upper surface of 102-1 is fitted with a pre-embedded plate 101 at the bottom of the beam, and the pre-embedded plate 101 at the bottom of the beam is provided with mounting holes corresponding to the upper anchor plate for the passage of the height-adjustable anchor bolts 2. The upper plate 102-1 and the pre-embedded plate 101 at the bottom of the beam are independent of each other. When adjusting the height-adjustable anchor bolts, there is no need to change the position height of the support. Only the height-adjustable anchor bolts need to be loosened, the pre-embedded plate at the bottom of the beam body lifted, the bridge body raised, the height-adjusting pad to be added to match the height to be adjusted, and the height-adjustable anchor bolts need to be lowered and tightened to achieve adjustment.

[0022] like Figure 2 As shown, the height-adjustable anchor bolt 2 includes a sleeve 201 , an anchor rod 202 , an adjustment bolt 203 , a deformation plate 204 and a nut 205 .

[0023] The lower end of the sleeve 201 is installed in the installation hole and supported on the upper surface of the upper seat plate 102. The sleeve 201 is provided with a deformable plate 204 and one end of the anchor rod 202 that are in clearance with the inner hole of the sleeve 201. The other end of the anchor rod 202 passes through the matching upper anchor hole and is fixed on the upper surface of the upper plate 102-1 by a nut 205. A through hole is provided in the center of the anchor rod 202, and the through hole is in clearance with the adjustment bolt 203. The adjustment bolt 203 is inserted from the lower end of the anchor rod 202 and extends from the other end and is threadedly connected with the deformable plate 204. The protruding part on the lower surface of the deformable plate 204 is a convex column, which is a part of the deformable plate, which can save economic costs, is easy to install, and has a reliable structure. A slot is provided on the upper surface of the anchor rod 202, and the convex column is arranged in the slot. When the adjustment bolt 203 rotates, the deformable plate is threadedly matched with the adjustment bolt, and the deformable plate moves up and down along the adjustment bolt. By rotating the adjusting bolt 203 , the deformable plate 204 is pressed against or away from the upper surface of the anchor rod 202 , and the deformable plate 204 is deformed and pressed against or away from the inner wall of the sleeve 201 , thereby achieving compression and fixation or contraction and relaxation.

[0024] like Figure 1 As shown, the deformation plate 204 is composed of an upper fixed plate 204 - 1 and a lower elastic block 204 - 2 , and the elastic block 204 - 2 is arranged close to the inner hole surface of the sleeve 201 . One of the settings is: the fixing plate 204-1 is threadedly connected with the adjusting bolt 203, the elastic block is annular, and when in a relaxed state, the outer surface of the ring is in a clearance fit with the inner surface of the sleeve, an integrated boss 207 is provided below the circular fixing plate 204-1, the boss 207 is arranged in the hole on the upper surface of the anchor rod, the number of bosses matches the number of holes, and the elastic block 204-2 below is tightened or loosened as the distance between the fixing plate 204-1 and the anchor rod 202 changes. Another setting is: the fixing plate 204-1 is fixedly connected with the adjusting bolt 203, the elastic block is a block-shaped block distributed in a ring shape, and when in a relaxed state, the outer surface of the ring is in a clearance fit with the inner surface of the sleeve, and the elastic block 204-2 below is tightened or loosened as the distance between the fixing plate 204-1 and the anchor rod 202 changes. Figure 4 , Figure 5As shown, the third setting form is: the outer surface of the anchor rod 202 and the fixing plate 204-1 of the height-adjusting support matches with the inner hole of the sleeve 201, and the upper part of the anchor rod 202 and the lower part of the fixing plate 204-1 are provided with a plurality of wedge-shaped grooves, and the elastic block 204-2 is placed in the wedge-shaped groove. Under the pressure of the fixing plate 204-1, the elastic block 204-2 can move in the groove along the wedge surface, and move radially toward the sleeve 201 at the same time, forming expansion and fixation. The fixing plate 204-1 of the height-adjusting support is integrally arranged with the boss 207, and one or more small holes are also arranged at the top of the anchor rod 202, forming a clearance fit with the boss 207. When the fixing plate 204-1 moves up and down, the boss 207 can move axially in the small hole of the anchor rod 202, and prevent the fixing plate 204-1 and the anchor rod 202 from relative rotation.

[0025] like Figure 5 As shown, for the third setting form of the deformable plate, the elastic block 204-2 can be set to a spherical or curved surface rotation shape, with a small hole in the center, and the annular spring 206 passes through the center hole of the elastic block 204-2 to connect multiple elastic blocks 204-2 into one. The elastic block 204-2 can be extended and retracted by the spring 206. The elastic block 204-2 can also be a protruding surface at one end that matches the groove of the sleeve 1, and a conical surface at the other end that matches the anchor rod 202 and the fixing plate 204-1. When the fixing plate 204-1 moves downward, it pushes the pressure ball to move outward to form a tight fixation.

[0026] The lower end of the sleeve 201 is provided with a stepped outer circle, and the stepped surface is respectively placed on the upper surface of the upper plate 102-1 and the upper surface of the beam bottom embedded plate 101, which can not only limit the position, but also prevent the sleeve from exceeding the lower bottom surface of the beam bottom embedded plate when adjusting the height.

[0027] The inner hole of the sleeve 201 of the height adjustment support is provided with multiple annular grooves, which cooperate with the deformable plate 204 when the anchor rod 6 is fixed to transmit the axial force of the anchor rod 202. The lower part of the sleeve 201 is embedded in the beam bottom embedded plate 101, and is cast together with the beam bottom embedded plate 101 at the bottom of the beam to form a beam body anchor body.

[0028] A thread is also provided at the lower part of the anchor rod 202 to cooperate with the nut 205 for tightening the support body. In order to prevent the anchor rod 202 from relative rotation during the tightening of the nut 205, a pair or more pairs of parallel planes are provided on the side surface of the anchor rod 202 located below the nut 205, which is convenient for tightening the anchor rod 202 using a wrench or other tools.

[0029] Example 1

[0030] like Figure 1 , Figure 4 , Figure 5It is mainly composed of an upper sleeve 201, a fixing plate 204-1, an elastic block 204-2, a spring 206, an adjusting bolt 203, an anchor rod 202, a beam bottom embedded plate 101, a support body, a nut 205, a boss 207, etc.

[0031] The lower part of the sleeve 201 in this embodiment is provided with a stepped outer circular structure, which is embedded in the installation hole of the beam bottom embedded plate 101 and cast together with the beam bottom embedded plate 101 at the bottom of the beam to form a beam body anchor body.

[0032] The inner hole of the sleeve 201 in this embodiment matches the anchor rod 202 and the outer surface of the fixing plate 204-1 with the inner hole of the sleeve 201. In the relaxed state, the anchor rod 202 and other components can move freely along the axis in the inner hole of the sleeve 201. A plurality of annular grooves are provided on the inner hole of the sleeve 201. When adjusting the height, the groove where the pressure ball is located can be selected according to the height adjustment amount to ensure that the anchor rod 202 is exposed to a suitable position on the bottom plane of the support upper seat plate. When the anchor rod 202 is in the fixed state, it matches with the elastic block 204-2 to transmit the axial force of the anchor rod 202.

[0033] In this embodiment, the upper part of the anchor rod 202 and the lower part of the fixing plate 204-1 are each provided with four corresponding wedge-shaped grooves, in which the elastic block 204-2 is placed. Under the pressure of the fixing plate 204-1, the elastic block 204-2 can move in the groove along the wedge surface and move radially toward the sleeve 201 to form expansion and fixation.

[0034] The fixing plate 204-1 in this embodiment is provided with two small holes, which form a tight fit with the boss 207. Two small holes are also provided on the top of the anchor rod 202, which form a clearance fit with the boss 207. When the fixing plate 204-1 moves up and down, the boss 207 can move axially in the small holes of the anchor rod 202, while preventing relative rotation between the fixing plate 204-1 and the anchor rod 202.

[0035] The anchor rod 202 in this embodiment is provided with an inner hole in the center, and a stepped hole is provided at the lower part of the anchor rod 202 for accommodating the head of the adjusting bolt 203. A thread is also provided at the lower part of the anchor rod 202 to cooperate with the nut 205 for fastening the support. In order to prevent the anchor rod 202 from relative rotation during the tightening of the nut 205, a pair or more pairs of parallel planes are also provided at the lower part of the anchor rod 202 to facilitate the use of a wrench or other tools to tighten or fix the anchor rod 202.

[0036] The adjusting bolt 203 in this embodiment is a hexagon socket head bolt, and an external thread is provided on the upper part of the adjusting bolt 203, which cooperates with the internal thread provided on the center of the fixing plate 204-1. By rotating the adjusting bolt 203, the fixing plate 204-1 can be axially moved to achieve the tightening and loosening of the elastic block 204-2.

[0037] The pressure ball 2 in this embodiment is spherical with a small hole in the center. The annular spring 206 passes through the center hole of the pressure ball 2 to connect multiple pressure balls 2 into one. The extension and retraction of the spring 206 can realize the extension and retraction of the pressure ball 2. When the adjusting bolt 203 is turned in the opposite direction, the fixing plate 204-1 moves upward, and the spring 206 contracts inward under the action of the elastic force, and finally is in a natural state. At this time, the outer surface of the pressure ball 2 is not higher than the outer surface of the anchor rod 202, which is convenient for the anchor rod 202 to move freely in the sleeve 201. When the adjusting bolt 203 is turned forward, the fixing plate 204-1 moves downward, pushing the elastic block 204-2 to move downward and outward along the wedge-shaped groove of the anchor rod 202 and the fixing plate 204-1. At this time, the elastic block 204-2 can be placed in the groove of the sleeve 201 by adjusting the axial movement of the anchor rod 202. The adjusting bolt 203 is continued to be turned forward to press the elastic block 204-2 and the sleeve 201 tightly to fix the anchor rod 202.

[0038] like Figure 3 As shown, the steps of adjusting the height of the support in this embodiment are as follows: remove the nut 205, reversely screw the adjusting bolt 203, the adjusting bolt 203 drives the fixing plate 204-1 to move upward, release the pressure on the elastic block 204-2, and the elastic block 204-2 is separated from the sleeve 201 under the action of the spring 206, and shrinks inside the outer surface of the anchor rod 202, push the anchor rod assembly into the sleeve 201, so that the lower end surface of the anchor bolt 6 does not expose the lower surface of the sleeve 201, tighten the adjusting bolt 203 in the forward direction, so that the anchor rod assembly is temporarily fixed in the sleeve 201, use the hydraulic jack to lift the beam body, add the height adjustment pad 4, and make the height adjustment pad 4 installation hole Align with the upper anchor hole of the upper seat plate, release the pressure of the hydraulic jack, let the beam fall back, turn the adjusting bolt 203 in the reverse direction, loosen the anchor rod assembly, move the anchor rod 202 downward, expose the appropriate length of the lower bottom surface of the support upper plate, and when the adjusting bolt 203 is turned forward, the fixed plate 204-1 moves downward, pushing the elastic block 204-2 to move downward and outward along the wedge-shaped groove of the anchor rod 202 and the fixed plate 204-1. At this time, slightly adjust the anchor rod 202 up and down so that the elastic block 204-2 is in the groove of the sleeve 201, continue to turn the adjusting bolt 203 forward to fix the anchor rod 202, install the nut 205 and tighten it, and complete the support height adjustment.

[0039] In this embodiment, the height adjustment support is fixed to different positions of the sleeve 201 by the anchor rod 202 to realize the anchor connection with the support when different height adjustment amounts are achieved. There is no problem of lengthening the anchor bolt design due to the height adjustment amount, and increasing the support height. The support and the sleeve at the bottom of the beam transmit horizontal force through the anchor rod 202, which can realize the height adjustment of the bridge structure in large settlement areas. The support is clearly stressed, and the height adjustment operation is convenient and fast. It can effectively save the support manufacturing cost and the height adjustment operation cost, and has good economic and social significance.
