Description

Technical Field

[0001] This utility model belongs to the field of rail transit technology, specifically relating to a steel spring floating plate tilt compensation piece. Background Technology

[0002] In the construction of steel spring floating slabs, after the planar position of the steel springs is determined, the area where the vibration isolators will be placed must be ground to ensure a flat base before the vibration isolators can be installed. Finally, the jacking construction is completed. Figure 1 As shown in the diagram. However, base grinding must be carried out within the space of the outer sleeve. The worker's operation is greatly restricted in the confined space of the outer sleeve, often resulting in poor base grinding quality and difficulty in completely resolving the problem of uneven base surfaces. Uneven base surfaces will cause the steel spring vibration isolator to become skewed, as shown in the diagram. Figure 2 and Figure 3 As shown in the image.

[0003] After the steel spring floating plate is lifted, the top surface of the vibration isolator cannot fully contact the supporting surface of the outer sleeve, meaning there is a gap between the shims on the steel spring vibration isolator and the supporting surface of the outer sleeve. Based on the number of gaps in each vibration isolator, this can be categorized as follows: Figure 2 The side shown is detached and as Figure 3 The two sides shown are detached, which affects the transmission of load on the floating slab. At the same time, the vibration isolator may become unstable under eccentric compression, posing a risk to train operation.

[0004] The traditional solution is to insert a certain number and thickness of shims into the gaps on the top surface of the vibration isolator. This method can temporarily solve the problem of load transfer of the floating plate. However, since the shims are only inserted into the gaps, the operating space is small and inconvenient during the lifting process. Moreover, the floating plate is subjected to strong vibrations during train operation. Since there are no fixing measures, the shims are prone to shifting or even falling off under the action of vibration loads, which will disrupt the force balance of the steel spring floating plate and affect the safety of train operation.

[0005] Therefore, in order to effectively solve the problem of voiding in rail transit, the applicant has developed a steel spring floating plate tilt compensation piece after long-term research and experimentation. This piece can quickly and efficiently fill voids with excellent filling effect, and the filled compensation piece will not fall off in subsequent work. Utility Model Content

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, the inventors have conducted intensive research and designed a steel spring floating plate tilt compensation plate. The main body of this compensation plate is annular, with one or two compensation angles extending outwards from the edge. These compensation angles can be rotated into the voided area. Before rotational filling, the appropriate type of compensation plate is selected based on the number of voids, and the appropriate number and thickness of compensation plates are selected based on the void height, thereby fully filling the voided area. A baffle plate is provided on the inner side of the compensation plate to ensure horizontal restraint during installation. A groove is created on the inner side of the compensation plate to allow for fixing with positioning bolts, preventing loosening and detachment due to vibration. Thus, this utility model is completed.

[0007] Specifically, the purpose of this utility model is to provide a steel spring floating plate tilt compensation piece, wherein the main body of the compensation piece is ring-shaped, and one or two compensation angles 1 extend outward from the outer side of the ring;

[0008] The outer contour of the compensation angle 1 includes an arc segment in the middle and straight segments on both sides of the arc segment, and the straight segments smoothly transition to the annular outer side of the compensation plate body.

[0009] The contour shape of the compensation angle 1 is consistent with the contour shape of the support claw 21 on the vibration isolator support plate 2.

[0010] The compensation angle 1 and the annular compensation plate body are an integral structure with basically the same thickness.

[0011] The inner contour dimensions of the annular compensation plate body are consistent with the inner contour dimensions of the height adjustment pad 3 above the vibration isolator.

[0012] Among them, three semi-circular grooves 4 are evenly distributed on the inner side of the annular compensation plate body, and the grooves 4 are used to accommodate positioning bolts.

[0013] Among them, three baffles 5 extend inward and downward from the inner side of the annular compensation plate body.

[0014] The steel spring floating plate tilt compensation piece is provided with various thickness specifications, including 1mm, 2mm, 3mm and 5mm.

[0015] Preferably, the material of the steel spring floating plate tilt compensation piece is stainless steel or galvanized Q235B steel.

[0016] The beneficial effects of this utility model include:

[0017] (1) The steel spring floating plate skew compensation piece provided by this utility model solves the problem of the gap between the upper pad of the vibration isolator and the outer sleeve support surface caused by the skew of the vibration isolator.

[0018] (2) The steel spring floating plate tilt compensation piece provided by this utility model is easy to install and has positioning capability.

[0019] (3) The steel spring floating plate tilt compensation piece provided by this utility model has the same cross-sectional dimensions as the shim when the compensation piece contacts the outer sleeve support surface, making the force transmission more stable. Attached Figure Description

[0038] 8-Steel spring floating plate skew compensation piece Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. While various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0040] This utility model provides a steel spring floating plate tilt compensation piece, such as... Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the main body of the compensation plate is ring-shaped, with one or two compensation angles 1 extending outward from the outer side of the ring; that is, there are two types of steel spring floating plate tilt compensation plates, one is a steel spring floating plate tilt compensation plate that extends by one compensation angle, and the other is a steel spring floating plate tilt compensation plate that extends by two compensation angles.

[0041] Preferably, the outer contour of the compensation angle 1 includes an arc segment in the middle and straight segments on both sides of the arc segment, and the straight segments smoothly transition to the annular outer side of the compensation plate body.

[0042] The contour shape of the compensation angle 1 is consistent with the contour shape of the support claw 21 on the vibration isolator support plate 2, and also with the contour shape of the support claw at the edge of the height adjustment shim 3. That is, the structural shape of the steel spring floating plate tilt compensation piece and the height adjustment shim 3 are similar, except that one or two support claws are missing. This arrangement can ensure that the load in the vertical direction is evenly transmitted.

[0043] Preferably, the compensation angle 1 and the annular compensation plate body are an integral structure with essentially the same thickness. It is preferably obtained through an integral stamping process.

[0044] Preferably, the inner contour dimension of the annular compensation plate body is consistent with the inner contour dimension of the height adjustment shim 3 above the vibration isolator.

[0045] Three semi-circular grooves 4 are evenly distributed on the inner side of the annular compensating plate body. These grooves 4 are used to accommodate positioning bolts. After the compensating plate is installed in place, rotational displacement is restricted by the positioning bolts; the positioning bolts are screwed and fixed to the vibration isolator support plate 2. Figure 5 and Figure 7 The image shows the bolt holes used to tighten the mounting positioning bolts.

[0046] Preferably, three baffles 5 extend inward and downward from the inner side of the annular compensation plate body. The baffles are evenly distributed, and the length of the baffles is basically the same as the thickness of a height adjustment shim; when installing the compensation plate, the horizontal displacement can be restricted by the baffles 5 to ensure that the compensation plate rotates around the axis.

[0047] Preferably, the steel spring floating plate tilt compensation piece is provided with multiple thickness specifications, including 1mm, 2mm, 3mm and 5mm; in the actual filling compensation work, multiple compensation pieces can be selected to fill together according to the specific void height.

[0048] Preferably, the material of the steel spring floating plate tilt compensation piece is stainless steel or galvanized Q235B steel.

[0049] This utility model also provides a method for filling voids, such as... Figure 8 and Figure 9 As shown in the figure, in this method, the steel spring floating plate tilt compensation piece 8 mentioned above is filled into the void, thereby filling the void.

[0050] Preferably, the method includes the following steps:

[0051] Step 1: Investigate the vibration isolators exhibiting voiding to determine the number and location of voids.

[0052] Step 2: Check the height of the gap using a feeler gauge, and select the corresponding type and thickness specification of steel spring floating plate skew compensation piece 8 accordingly.

[0053] Step 3: Use a jack to lift the floating plate, place the steel spring floating plate tilt compensation piece outside the area to be filled, and then rotate the compensation piece 60° around the axis to fill the empty area with the compensation angle 1 of the compensation piece.

[0054] Preferably, in step 1, the pads at the three support surfaces of the vibration isolator are hammered with a small hammer, and the sound is used to determine whether the pads are compacted. If the pads are not compacted, there is a void.

[0055] Preferably, in step 2, when the number of empty spaces is one, a steel spring floating plate tilt compensation piece with a compensation angle is selected;

[0056] When there are two voids, select a steel spring floating plate with two compensation angles for tilt compensation; when there are three voids on the vibration isolator, height adjustment shims need to be installed.

[0057] Preferably, to compensate for the compression of the steel spring floating plate tilt compensation piece, the total thickness of the compensation piece is selected to be 1-3 mm larger than the measured clearance height.

[0058] Example

[0059] A 500-meter-long test track was selected, and a floating plate with steel spring vibration isolators was laid on it. There were 20 steel spring vibration isolators with gaps. The gaps were filled by the following method.

[0060] Step 1: Use a small hammer to strike the pads at the three support surfaces of the vibration isolator. Determine whether the pads are compacted based on the sound. If the pads are not compacted, there is a gap. This will help determine the number and location of the gaps.

[0061] Step 2: Check the height of the void using a feeler gauge, and select the corresponding type and thickness of steel spring floating plate skew compensation piece 8 accordingly; when there is one void, select a steel spring floating plate skew compensation piece with one compensation angle; when there are two voids, select a steel spring floating plate skew compensation piece with two compensation angles; the total thickness of the compensation piece should be 1-3 mm greater than the measured void height.

[0062] Step 3: Use a jack to lift the floating plate, place the steel spring floating plate tilt compensation piece outside the area to be filled, and then rotate the compensation piece 60° around the axis to fill the empty area with the compensation angle 1 of the compensation piece.

[0063] Five operators worked together and completed the filling and repair work on the 20 steel spring vibration isolators that had become detached in 10 hours.

[0064] After 100 trains passed over the 500-meter-long test track, 20 steel spring vibration isolators that had come loose were inspected. It was found that the steel spring floating plate tilt compensation pieces that were filled during the repair were all intact, without any damage or displacement, and were able to bear and transmit the load normally.

[0065] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and serve only an illustrative purpose. Based on this, various substitutions and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
