Description

Technical Field

[0001] The present invention relates to a floating slab sleeve, and more particularly to a sleeve with adjustable support position and a method for adjusting the sleeve height. Background Art

[0002] In the field of rail transit vibration reduction, the steel spring or rubber spring floating slab system is currently the highest-level vibration reduction system. The floating slab system consists of a concrete slab, an outer sleeve embedded in the concrete slab, a vibration isolator (also known as an inner sleeve) installed in the outer sleeve later, a height-adjusting pad, a locking pad, and other main key components. Only when all components cooperate well can a good vibration reduction function be achieved.

[0003] In the prior art, the outer sleeve generally has a jacking layer and a support layer. As shown in Figure 1 When height adjustment is required, several height-adjusting pads are arranged between the support layer of the outer sleeve and the vibration isolator, as shown in Figure 2 During the jacking of the floating slab construction, the pads need to be inserted one by one and then adjusted one by one into place, resulting in low construction efficiency and high cost of the height-adjusting pads. Moreover, the installation process of the height-adjusting pads is cumbersome, requiring a high technical level of the operator and taking a long time.

[0004] Due to the above reasons, the inventor of the present invention has conducted in-depth research on the existing sleeves, hoping to design a new sleeve and a method for adjusting the sleeve height that can solve the above problems. Summary of the Invention

[0005] In order to overcome the above problems, the inventor of the present invention has conducted intensive research and designed a sleeve and an adjustment method capable of continuously adjusting the support position. The device includes multiple support surfaces fixedly installed in the cylinder body. The vibration isolator can abut against the bottom of any one of the support surfaces. By adjusting the position of the specific abutting support surface, the overall assembly height dimension of the sleeve and the vibration isolator can be adjusted, thus completing the present invention.

[0006] Specifically, the object of the present invention is to provide a sleeve capable of continuously adjusting the support position. The sleeve is embedded in the floating slab and includes a cylinder body 1. Multiple support surfaces 2 are provided on the inner wall of the cylinder body 1.

[0007] A vertical channel 4 for the vibration isolator 3 to enter is provided in the middle of the cylinder body 1.

[0008] Support claws 5 are provided on the vibration isolator 3.

[0009] By rotating the vibration isolator 3 placed in the vertical channel 4, the support claws 5 are made to abut against the lower surface of any one of the support surfaces 2.

[0010] Among them, 2 to 10 layers of the support surfaces 2 are provided.

[0011] Each layer of the support surface 2 includes a plurality of support blocks 21 independently fixed to the inner wall of the cylinder 1;

[0012] Preferably, each supporting surface 2 includes 2 to 4 supporting blocks 21 .

[0013] The lower surfaces of the plurality of support blocks 21 constituting the same support surface 2 are coplanar.

[0014] The support blocks 21 in two adjacent layers of support surfaces 2 are arranged alternately in the vertical direction.

[0015] The support blocks 21 in adjacent support surfaces 2 are connected to each other and arranged in a step-like manner as a whole, and the support claws 5 are horizontally limited by their connection parts.

[0016] The present invention also provides a method for adjusting the height of a floating plate, wherein the above-mentioned sleeve is pre-embedded in the floating plate, and a vibration isolator is installed in the sleeve; the method comprises the following steps:

[0017] Step a, pressing the vibration isolator 3 so that the support claw 5 on the vibration isolator 3 moves downward and is out of contact with the support block 21, or lifting the floating plate so that the support block 21 moves upward together with the sleeve and is out of contact with the support claw 5;

[0018] Step b, rotating the vibration isolator 3 so that the supporting claw 5 is rotated out from under the current supporting block 21 and rotated under another supporting block 21;

[0019] Step c, releasing the pressure on the vibration isolator 3, or releasing the lifting of the floating plate, so that the top surface of the supporting claw 5 is in contact with the bottom surface of another supporting block 21 and transmits force;

[0020] Step d, repeating steps a, b and c until the vibration isolator 3 is adjusted to a desired height position.

[0021] Wherein, in each of the floating plates, two rows of sleeves are pre-buried along the extending direction of the rails, and each row includes at least 4 sleeves.

[0022] Wherein, in step a, the vibration isolator 3 is compressed by a jack cylinder pressure system, or the floating plate is lifted by a jack.

[0023] Wherein, installing the sleeve to the vibration isolator comprises the following steps:

[0024] Step 1: Place the vibration isolator 3 in the vertical channel 4 of the cylinder 1.

[0025] Step 2, pressing the vibration isolator 3 so that the support claw 5 on the vibration isolator 3 moves downward, or lifting the floating plate so that the support block 21 to be used moves upward together with the sleeve until the top surface height of the support claw 5 is less than the bottom surface height of the support block 21 to be used;

[0026] Step 3: Rotate the vibration isolator 3 or the cylinder 1 so that the support claw 5 is screwed under the support block 21 to be used.

[0027] Step 4: Release the pressure on the vibration isolator 3 or the jacking of the floating plate so that the top surface of the support claw 5 is in contact with the bottom surface of the support block 21 to be used and transmits force.

[0028] The beneficial effects of the present invention include:

[0029] (1) According to the sleeve capable of continuously adjusting the support position and the height adjustment method provided by the present invention, the installation process of the vibration isolator can be simplified. There is no need to select the number and thickness of the shims according to the specific working conditions. Only by rotating the vibration isolator can the appropriate height be quickly adjusted, simplifying the installation process and reducing the installation difficulty.

[0030] (2) According to the sleeve capable of continuously adjusting the support position and the height adjustment method provided by the present invention, when settlement and other conditions occur in some areas, the support height of the vibration isolator can be adjusted by rotating the vibration isolator and abutting the vibration isolator against the support surfaces at different height positions, so as to quickly and effectively eliminate the adverse effects brought by settlement and other conditions.

[0050] The present invention will be further described in detail below with reference to the drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become more clear and definite.

[0051] The special word "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0052] A sleeve with continuously adjustable support position provided according to the present invention, as Figure 3 , Figure 4 shown, the sleeve includes a cylinder 1, both ends of the cylinder 1 are transparent, and the cross-sectional shape is circular or regular polygon. The sleeve can be prepared from metal or non-metal materials, and its processing technology can adopt techniques such as welding, casting, or 3D printing.

[0053] The sleeve is embedded in the floating slab, and a vibration isolator is installed in the sleeve. The bottom end of the vibration isolator extends out from the bottom of the floating slab and abuts against the foundation, so as to support the sleeve and the floating slab through the vibration isolator.

[0054] On the inner wall of the cylinder body 1, multiple support surfaces 2 are provided. The support surfaces 2 can be fixed to the inner wall by welding or integrally formed with the sleeve.

[0055] In the middle of the cylinder body 1, a vertical channel 4 for the vibration isolator 3 to enter is provided. As Figure 5 shown, the cross-sectional shape and size of the vertical channel 4 can just allow the vibration isolator 3 to enter. After the vibration isolator 3 rotates a certain angle, it cannot be taken out from the vertical channel 4.

[0056] On the vibration isolator 3, support claws 5 are provided. The number of the support claws 5 needs to be selected according to the structural form of the cylinder body 1. Preferably in this application, the vibration isolator 3 is a spring vibration isolator.

[0057] By rotating the vibration isolator 3 placed in the vertical channel 4, the support claws 5 are made to abut against the lower surface of any one layer of the support surface 2. Since the heights of different support surfaces 2 are different, when the support claws 5 abut against the lower part of different support surfaces, the total height of the sleeve and the vibration isolator is different, thus achieving the purpose of height adjustment.

[0058] In a preferred embodiment, the support surfaces 2 are provided with 2 to 10 layers. The more layers of the support surfaces are provided, the finer the height adjustment ability is and the more adjustable gears there are, and it can be selected and designed according to specific working conditions requirements. Figure 3 The schematic diagram showing the setting of 2 layers of support surfaces is shown in Figure 6 The schematic diagram showing the setting of 10 layers of support surfaces is shown in

[0059] In a preferred embodiment, each layer of the support surface 2 includes a plurality of support blocks 21 independently fixed to the inner wall of the cylinder body 1; further, the support surface 2 is composed of a plurality of support blocks 21, and there is a certain gap between these support blocks 21 and they do not contact each other.

[0060] Preferably, each layer of the support surface 2 includes 2 to 4 support blocks 21. The number of support blocks 21 in each layer of the support surface 2 is the same as the number of support claws 5, so that the support claws 5 correspond to each support block 21 one by one. When the support claws 5 are in close contact with the support surface 2, each support claw 5 is in close contact with one support block 21.

[0061] In a preferred embodiment, the lower surfaces of the plurality of support blocks 21 constituting the same support surface 2 are coplanar, so that the support claws 5 and the support blocks 21 can be in full and close contact, the overall force is balanced, and the force transmission is stable.

[0062] In a preferred embodiment, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、Figure 9 and Figure 10 As shown in , the support blocks 21 in two adjacent layers of support surfaces 2 are arranged in a staggered manner in the vertical direction. Thus, the support claws 5 can be rotated from directly below one layer of support surface to directly below another adjacent layer of support surface by rotating at a small angle.

[0063] Preferably, the support blocks 21 in adjacent support surfaces 2 are connected to each other and arranged in a stair-like manner as a whole, and the support claws 5 are horizontally limited by their connection parts. Specifically, the number of support blocks included in each layer of support surface is the number of steps, and one support block is taken out from each layer of support surface to form a step around the inner wall of the cylinder 1, such as Figure 6 , Figure 8 and Figure 10 as shown in .

[0064] In a preferred embodiment, the distance between two adjacent layers of support surfaces can be selected and set according to the height dimension of each jacking construction and the number of support surface layers set.

[0065] The present invention also provides a method for adjusting the height of a floating plate, the method comprising the following steps:

[0066] The above-mentioned sleeve is embedded in the floating plate, and a vibration isolator is installed in the sleeve; Figure 11 As shown in

[0067] Step a, pressing the vibration isolator 3 so that the support claw 5 on the vibration isolator 3 moves downward and is out of contact with the support block 21; or lifting the floating plate so that the support block 21 moves upward together with the sleeve and is out of contact with the support claw 5; continue to press the vibration isolator 3 downward, or lift the floating plate upward, until the vibration isolator 3 can rotate in the cylinder 1;

[0068] Step b, rotating the vibration isolator 3 so that the supporting claw 5 is rotated out from under the current supporting block 21 and rotated under another supporting block 21;

[0069] Step c, releasing the pressure on the vibration isolator 3, or releasing the lifting of the floating plate, so that the top surface of the supporting claw 5 is in contact with the bottom surface of another supporting block 21 and transmits force;

[0070] Step d, repeating steps a, b and c until the support member is adjusted to a desired height position.

[0071] Preferably, in each of the floating plates, two rows of sleeves are pre-buried along the extension direction of the rails, and each row includes at least 4 sleeves.

[0072] Preferably, in step a, the vibration isolator 3 is compressed by a jack hydraulic system, or the floating plate is lifted by a jack.

[0073] Preferably, installing the sleeve into the vibration isolator includes the following steps:

[0074] Step 1: Place the vibration isolator 3 in the vertical channel 4 of the cylinder 1.

[0075] Step 2: Compress the vibration isolator 3 to move the upper support claws 5 of the vibration isolator 3 downward, or jack up the floating plate to move the to-be-used support block 21 upward together with the sleeve until the top surface height of the support claws 5 is less than the bottom surface height of the to-be-used support block 21.

[0076] Step 3: Rotate the vibration isolator 3 or the cylinder 1 to screw the support claws 5 under the to-be-used support block 21.

[0077] Step 4: Release the compression on the vibration isolator 3 or the jacking up of the floating plate so that the top surface of the support claws 5 is in contact with and transfers force to the bottom surface of the to-be-used support block 21.

[0078] Preferably, in this application, the to-be-used support block refers to the support block that specifically abuts against the support claws after installation according to the required design height.

[0079] More preferably, when the top surface of the support claws 5 is in contact with the bottom surface of the to-be-used support block 21, if it is found that the overall height of the floating plate is inappropriate, the vibration isolator 3 can be compressed again or the floating plate can be jacked up to disengage the support claws 5 from the support block 21 above. If the overall height of the floating plate is too high, rotate the support claws 5 under the lower support surface; if the overall height of the floating plate is too low, rotate the support claws 5 under the higher support surface.

[0080] Embodiment:

[0081] Select the floating plate as shown in Figure 11 and Figure 12 , with a length of 3.6 m, a width of 2.7 m, a thickness of 0.33 m, and a weight of 7800 kg, and 6 sleeves as shown in Figure 3 and Figure 4 embedded therein;

[0082] The specific construction process of this floating plate is as follows:

[0083] Place this floating plate on the roadbed and adjust it to the appropriate position;

[0084] Place the vibration isolator in the vertical channel of the cylinder.

[0085] Compress the vibration isolator through the hydraulic system of the jack cylinder to move the upper support claws of the vibration isolator downward until the top surface height of the support claws is less than the bottom surface height of the to-be-used support block. The vibration isolator can rotate in the cylinder.

[0086] Rotate the vibration isolator so that the support claw is screwed under the support block to be used;

[0087] Release the pressure on the vibration isolator so that the top surface of the support claw fits against the bottom surface of the support block to be used and transmits force.

[0088] The time required to install all the isolators on a floating plate is 10-15 minutes.

[0089] The average installation time of a traditional floating slab that adjusts its height by raising the pad is 30-50 minutes.

[0090] When the ballast under the floating slab is empty and the support effect of the vibration isolator on the embedded sleeve in the floating slab is weakened or lost, the floating slab system is repaired by adjusting the support position of the vibration isolator. The process of repairing and eliminating empty hanging is as follows:

[0091] The jack hydraulic system presses the vibration isolator, causing the support claw on the vibration isolator to move downward and break away from the support block.

[0092] Rotate the vibration isolator so that the support claw is rotated out from under the current support block and rotated under another support block at a lower position; release the pressure on the vibration isolator so that the top surface of the support claw is in contact with the bottom surface of another support block and transmits force;

[0093] Repeat the above steps until the vibration isolator is adjusted to the desired height, so that the bottom end of the vibration isolator abuts against the bottom of the empty suspension area, and the top end fits against and transmits force to the bottom surface of the support block, thereby offsetting the adverse effects of the empty suspension; the overall maintenance process takes 20-25 minutes / meter, and there is no need to lift the floating plate or add a height adjustment pad during the maintenance process.

[0094] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve only as an illustration. On this basis, the present invention may be subjected to a variety of substitutions and improvements, all of which fall within the scope of protection of the present invention.
