[0011] A height adjustment method for a tape-wound spherical height adjustment support includes the following steps:

[0012] S1. Preliminary inspection and preparation: Comprehensively inspect each component of the jack, the upper beam body, the upper support base, and the lower support base to ensure that they are intact and have normal functions. At the same time, confirm that the silicon grease is applied to the spherical slide plate and the surface treatment of the spherical crown liner meets the standards. Place the jack in the appropriate position and firmly support it, and clean the sundries in the jacking area;

[0013] S2. Jack up and separate the beam body: Start the jack and slowly jack up the upper beam body to separate the upper support base and the upper support assembly at its bottom from the lower support base. During the process, pay attention to the contact state of the compression spring and the connecting side plate to ensure smooth separation;

[0014] S3. Determine and jack up to the appropriate height: According to the design value and operation requirements, operate the jack to jack up the upper beam body to the appropriate height, and auxiliary measurement tools can be used for confirmation.

[0015] S4. Perform the tape winding operation: Use tools to rotate the second roller, drive the rotation of the conveyor belt, and wind the pre-stored tape outside the first roller. During this period, closely monitor the winding state to ensure uniform and neat winding.

[0016] S5. Confirm that the tape winding thickness meets the standard: Continuously wind until the overlapping thickness of the conveyor belt meets the pre-calculated height adjustment requirements, and judge by measurement or marking.

[0017] S6. Fix the rollers: First, tighten the nuts to initially lock the first roller and the second roller, and then insert the split pin and bend it open to complete double fixation.

[0018] S7. Lower the beam to complete the height adjustment: Operate the jack to reset and lower the beam. The upper beam body pushes the upper support seat downward, and the upper support assembly moves to the top of the conveyor belt. Wait until the support plate abuts against the conveyor belt to achieve height adjustment. Finally, recheck the equipment status.

[0019] The beneficial effects of the present invention are as follows:

[0020] For the tape-winding spherical height-adjustable bearing and a bearing height-adjustment method of the present invention, during the operation process, the operator rotates the second roller, and drives the conveyor belt to convey by means of the friction force between it and the conveyor belt, accurately pulls out the pre-stored tape on the first roller and winds it outside the conveyor belt. By real-time monitoring of the overlapping thickness of the conveyor belt, the rising height of the upper beam body can be accurately controlled to meet the stringent requirements of various projects for the height adjustment accuracy, ensuring the accuracy and reliability of height adjustment. As the overlapping thickness of the conveyor belt increases, it can provide a stable support for the upper support seat and the upper beam body. After the beam is lowered, the pressure can be evenly dispersed, reducing the single-point force, ensuring the stability of the upper beam body at the new height, and avoiding potential safety hazards such as displacement and deformation. Moreover, this tape-winding height-adjustment method has extremely strong adaptability, is not overly restricted by the beam type, size and working environment. Whether it is large-scale bridge construction or small-scale building structure height adjustment, it can be flexibly handled by adjusting parameters such as the length of the pre-stored tape, the material and specifications of the conveyor belt. The operation process is clear and simple, without the need for complex equipment and tools, reducing the operation difficulty and labor cost, effectively improving the operation efficiency, shortening the project cycle, and showing excellent application value in actual projects.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] Such as Figures 1 to 12As shown in the figure, a coiled-tape spherical height-adjustable support of an embodiment of the present invention includes a lower beam body 1, an upper beam body 2, a lower support seat 4, and an upper support seat 5. An upper beam body 2 is arranged above the lower beam body 1. Jacks 3 are installed on both sides of the top of the lower beam body 1. The pushing ends at the tops of the jacks 3 are fixedly connected to the bottom of the upper beam body 2. A lower support seat 4 is installed at the middle position of the top of the lower beam body 1. An upper support seat 5 is installed at the middle position of the bottom of the upper beam body 2. The position of the upper support seat 5 corresponds exactly to that of the lower support seat 4. An upper support assembly is arranged at the bottom of the upper support seat 5. A lower support assembly is arranged inside the lower support seat 4. Sleeve anchor bolts 6 are installed at the four corners of the lower support seat 4 and the upper support seat 5.

[0037] The lower support assembly includes a first roller 41 and a second roller 44 arranged on both sides inside the lower support seat 4. The first roller 41 is close to the two side walls inside the lower beam body 1. The second roller 44 on the left is located at the lower right position of the first roller 41 on the left. The second roller 44 on the right is located at the lower left position of the first roller 41 on the right. Roller holes 411 are provided at the front and rear ends of the first roller 41. The roller holes 411 are opened at the front and rear ends of the lower support seat 4. The front and rear ends of the first roller 41 protrude from the front and rear ends of the lower support seat 4 through the roller holes 411. Strip-shaped holes 441 are provided at the front and rear ends of the second roller 44. The strip-shaped holes 441 are opened at the front and rear ends of the lower support seat 4. The front and rear ends of the second roller 44 protrude from the front and rear ends of the lower support seat 4 through the strip-shaped holes 441. Pull springs 46 are arranged at the two ends of two adjacent first rollers 41 and second rollers 44. One end of the pull spring 46 is connected to the first roller 41, and the other end of the pull spring 46 is connected to the second roller 44.

[0038] A pre-stored tape 412 is wound around the outside of the first roller 41. A rotary tape 442 is arranged outside the two second rollers 44. One end of the pre-stored tape 412 outside the first roller 41 on the left is led out from the bottom of the first roller 41 and fixedly connected to the bottom of the rotary tape 442. One end of the pre-stored tape 412 outside the first roller 41 on the right is led out from the top of the first roller 41 and fixedly connected to the top of the rotary tape 442. A statistical slide bar 45 is arranged on one side wall of the lower support seat 4.

[0039] Nuts 47 are externally threaded on the first roller 41 and the second roller 44 protruding from the front and rear ends of the lower support seat 4. Pin holes 49 are opened at the two ends of the first roller 41 and the second roller 44. Split pins 48 are inserted into the pin holes 49. The split pins 48 are located at one end of the nuts 47. Threaded holes 421 are opened on both sides at the front and rear ends of the inner bottom wall of the lower support seat 4. Studs 42 are threadedly connected to the inside of the threaded holes 421. The studs 42 are located at the front and rear ends of the rotary tape 442. Compression springs 43 are wound around the outside of the studs 42.

[0040] The upper support assembly includes a flat slide plate 51 disposed at the middle position of the bottom of the upper support base 5. A spherical crown liner 52 is fixed to the bottom of the flat slide plate 51. A spherical slide plate 53 is disposed at the bottom of the spherical crown liner 52. A support plate 54 is disposed at the bottom of the spherical slide plate 53. The support plate 54 is placed inside the lower support base 4 and abuts against the top of the rotary belt 442. Two connecting side plates 55 are respectively fixed at both ends of the support plate 54. The docking holes in the connecting side plates 55 are sleeved outside the stud 42 and abut against the top of the compression spring 43. The inner side wall of the stop block at one end of the bottom of the upper support base 5 is provided with a side stainless steel 56.

[0041] Specifically, silicone grease is applied on the spherical slide plate 53 and welded to the bottom of the upper support base 5 with the flat slide plate 51 to form a sliding surface.

[0042] The spherical surface of the spherical crown liner 52 is polished and chrome-plated or covered with mirror stainless steel.

[0043] The pre-storage belt 412 and the rotary belt 442 can be made of metal but are not limited to metal.

[0044] High-friction materials are coated on the first roller 41 and the second roller 44.

[0045] The first roller 41 and the second roller 44 are connected to the symmetric side rollers by a synchronizer.

[0046] The pulling force of the tension spring 46 shall not be less than the frictional force required for the second roller 44 to drive the rotary belt 442 to roll.

[0047] The total elastic force of the compression spring 43 shall not be lower than the weight of the support plate 54 and can enable it to move upward by a certain range, and the range depends on the height adjustment design value.

[0048] Hexagons are machined at the ends of the first roller 41 and the second roller 44 to facilitate the fitting and rotation of tools.

[0049] Furthermore, in the actual operation scenario, when it is necessary to perform a height adjustment operation on the upper beam body 2, first, the operator will precisely control the jack 3 to steadily and evenly lift the upper beam body 2 upward. As the jack 3 continuously exerts force, the upper beam body 2 gradually rises, and the upper support base 5 and the upper support assembly tightly connected to its bottom also rise slowly, and then gradually separate from the lower support base 4. During this process, the connecting side plate 55 pressing the compression spring 43 moves upward synchronously due to the upward movement of the upper support base 5. And the compression spring 43 itself has a strong elastic potential energy. When the connecting side plate 55 moves upward, the compression spring 43 quickly moves upward and resets, and by virtue of its own elastic force, finally firmly abuts against the bottom of the connecting side plate 55, continuously providing a stable supporting force to ensure the stability of the structure during the dynamic adjustment process.

[0050] The operator continuously uses the jack 3 to slowly jack up the beam body 2, constantly paying attention to the rising height of the beam body 2 until it reaches a suitable position that meets the engineering requirements. At this time, the operator begins to rotate the two second rollers 44. Under the precise operation of the operator, the second rollers 44 rotate stably in the established direction. By virtue of the tight frictional force between them and the rotary belt 442, the rotary belt 442 is driven to convey orderly outside it. As the rotary belt 442 continuously conveys, its powerful pulling force acts on the pre-stored belt 412 outside the first roller 41, pulling out the pre-stored belt 412 little by little and winding it orderly around the outside of the rotary belt 442. As the winding process continues, the overlapping thickness of the rotary belt 442 is also continuously increasing.

[0051] The operator constantly monitors the overlapping thickness of the rotary belt 442. When the overlapping thickness precisely reaches the value required by the project, the next operation is immediately carried out. First, the operator picks up the nut 47 and skillfully screws it onto both ends of the first roller 41 and the second roller 44. Under the tightening action of the operator, the nut 47 gradually fits tightly with the first roller 41 and the second roller 44, initially locking the first roller 41 and the second roller 44 and effectively restricting their rotation. Immediately afterwards, the operator takes out the split pin 48 and inserts the split pin 48 into the specially set jacking hole at the rear end of the nut 47. At the same time, the split pin 48 is accurately aligned with the pre-processed pin holes 49 at both ends of the first roller 41 and the second roller 44 and gently inserted until the split pin 48 is completely embedded in the pin holes 49. After this series of operations, the first roller 41 and the second roller 44 are firmly fixed to ensure that there will be no accidental rotation during the subsequent operation process.

[0052] Finally, reset the jack 3 to perform the beam lowering operation. The beam body 2 will push the upper support seat 5 downward. The bottom of the upper support seat 5 consists of an upper support assembly composed of a flat slide plate 51, a spherical crown liner 52, a spherical slide plate 53 and a support plate 54. The downward movement of the upper support seat 5 will drive the upper support assembly to move into the top of the overlapping rotary belt 442 inside the lower support seat 4. Since the rotary belt 442 overlaps with a certain thickness, when the bottom of the support plate 54 abuts against the top of the rotary belt 442, the overlapping rotary belt 442 increases the position of the support plate 54, changing the position height of the upper support seat 5. At this time, the height between the lower beam body 1 and the upper beam body 2 increases, and thus the height adjustment operation can be completed.

[0053] A height adjustment method for a belt - winding spherical height - adjusting bearing, the height adjustment method comprising the following steps:

[0054] S1. Preliminary inspection and preparation: Comprehensively inspect each component of the jack 3, the beam body 2, the upper support seat 5, and the lower support seat 4 to ensure that they are intact and have normal functions. At the same time, confirm that the greasing of the spherical slide plate 53 and the surface treatment of the spherical crown liner 52 meet the standards. Place the jack 3 in a proper position and firmly support it, and clean the sundries in the jacking area;

[0055] S2, lifting and separating the beam body: start the jack 3, slowly lift up the upper beam body 2, so that the upper support seat 5 and its bottom upper support assembly are separated from the lower support seat 4. During the process, pay attention to the conflict state between the compression spring 43 and the connecting side plate 55 to ensure smooth separation;

[0056] S3. Determine and lift the appropriate height: According to the design value and operation requirements, operate the jack 3 to lift the upper beam 2 to the appropriate height, and measurement tools can be used to assist in confirmation;

[0057] S4, perform the tape winding operation: rotate the roller 2 44 with the aid of a tool to drive the rotary belt 442 to be transported so that it winds up the pre-stored tape 412 outside the roller 1 41, and closely monitor the winding state during the process to ensure that the winding is uniform and neat;

[0058] S5. Confirm that the thickness of the tape meets the standard: Continue winding until the overlapping thickness of the rotary tape 442 meets the height adjustment requirement calculated in advance, which is determined by measurement or marking;

[0059] S6, fixing the rollers: first tighten the nut 47 to preliminarily lock the roller 1 41 and the roller 2 44, then insert the split pin 48 and pry open the split pin to complete the double fixation;

[0060] S7, the height adjustment of the dropped beam is completed: operate the jack 3 to reset the dropped beam, the upper beam body 2 pushes the upper support seat 5 to move downward, and the upper support assembly moves to the top of the rotating belt 442, and waits for the support plate 54 to be tightly pressed against the rotating belt 442 to achieve the height adjustment, and finally review the equipment status.
