Description

Technical Field

[0001] The invention patent relates to the field of track vibration control technology, specifically a waterproof square track vibration isolator. Background Art

[0002] At present, the floating slab track structure of urban rail transit mainly adopts steel spring isolators. Steel spring isolators can be divided into circular isolators and square isolators according to their appearance. In the prefabricated steel spring floating slab, the combination of circular isolators and square isolators has better economic benefits than the solution of using circular isolators alone. At present, the waterproof structure of circular isolators is relatively mature, that is, water hose sheaths and clamps are used as waterproof structures. However, when the water hose sheath and clamp waterproof structure are applied to square isolators, the waterproof effect is poor, and the clamp damage rate is high, and the economic benefits are poor. Now it is necessary to design a stable and low-cost waterproof structure for square isolators to extend the service life of square isolators.

[0003] Invention patent content

[0004] The purpose of this patent is to provide a waterproof square track vibration isolator to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the patent of the present invention provides the following technical solutions: a waterproof square track vibration isolator, comprising a top cover and a base, wherein the bottom end of the top cover and the top end of the base are welded with a surrounding frame, and a spring group array is welded between the top cover and the base located in the surrounding frame, wherein the spring group array is composed of a plurality of springs, and a waterproof adhesive layer A is brushed on the outer wall of the surrounding frame, and a waterproof tape is wrapped and bonded on the outer walls of the two surrounding frames, and the waterproof tape covers the waterproof adhesive layer A and the gap between the two surrounding frames.

[0006] Furthermore, an upper spring stop tube and a lower spring stop tube are respectively embedded and slidably arranged in the inner sides of both ends of the spring, the top end of the upper spring stop tube is welded and fixed to the bottom end of the top cover, and the bottom end of the lower spring stop tube is welded and fixed to the top end of the base.

[0007] Furthermore, two groups of connecting tubes are symmetrically and welded on the top of the base located on both sides of the frame, and each group of connecting tubes has at least one. The top of the top cover is provided with locking bolts equal to the number of connecting tubes. The locking bolts pass through the top of the top cover and are threadedly connected to the inner wall of the corresponding side connecting tube.

[0008] Furthermore, one end of the waterproof tape covers the other end of the waterproof tape.

[0009] Furthermore, a waterproof adhesive layer B is applied to the joint between the edge of the waterproof tape and the outer wall of the frame and the joint between the two layers of waterproof tape.

[0010] The beneficial effects achieved by the present invention are:

[0011] 1. The waterproof tape covers the waterproof adhesive layer A and the gap between the two frames, effectively closing any possible tiny gaps or joints to prevent moisture from penetrating. At the same time, the waterproof tape also provides an additional physical barrier to enhance the water resistance of the overall structure. The waterproof adhesive layer B is applied to the joints between the edge of the waterproof tape and the outer wall of the frame and the joints between the two layers of waterproof tape, effectively filling the tiny gaps or imperfect fits that may exist at the joints of the waterproof tape, while also increasing the connection strength between the edge of the waterproof tape and the frame. The waterproof adhesive layer A is able to resist external moisture and prevent it from penetrating into the interior of the isolator through the gap between the frame and the waterproof tape. One end of the waterproof tape covers the other end to form a tighter and continuous waterproof barrier. This overlapping design can reduce the possibility of moisture penetrating through the joints at the ends of the waterproof tape.

[0012] 2. The cost of using waterproof glue and waterproof tape is lower than that of rubber belt and clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3 As shown, the patent of the present invention discloses a waterproof square track vibration isolator, including: a top cover 1 and a base 2, a frame 3 is welded to the bottom end of the top cover 1 and the top end of the base 2, a spring group array 4 is welded between the top cover 1 and the base 2 located in the frame 3, the spring group array 4 is composed of a plurality of springs, a waterproof adhesive layer A5 is brushed on the outer wall of the frame 3, a waterproof tape 6 is wrapped and bonded on the outer walls of the two frames 3, and the waterproof tape 6 covers the waterproof adhesive layer A5 and the gap between the two frames 3.

[0018] Further, such as Figure 2 As shown, an upper spring stop tube 41 and a lower spring stop tube are respectively embedded and slidably arranged in the inner sides of both ends of the spring, the top end of the upper spring stop tube 41 is welded and fixed to the bottom end of the top cover 1, and the bottom end of the lower spring stop tube is welded and fixed to the top end of the base 2.

[0019] Further, such as Figure 1-2As shown, two groups of connecting tubes 7 are symmetrically and welded on the top of the base 2 located on both sides of the frame 3, and each group of connecting tubes 7 has at least one. The top of the top cover 1 is provided with locking bolts 8 equal in number to the connecting tubes 7. The locking bolts 8 pass through the top of the top cover 1 (the top cover 1 is provided with a through hole for the locking bolts 8 to pass through), and are threadedly connected to the inner wall of the corresponding side connecting tube 7.

[0020] Further, such as Figure 3 As shown, one end of the waterproof tape 6 covers the other end of the waterproof tape 6 .

[0021] Further, such as Figure 3 As shown, the joints between the edge of the waterproof tape 6 and the outer wall of the surrounding frame 3 and the joints between the two layers of waterproof tape 6 are all brushed with a waterproof adhesive layer B8.

[0022] Based on the above structure, Figure 1-3 As shown, during assembly, the surrounding frame 3 is first welded to the bottom end of the top cover 1 and the top end of the base 2 respectively, and then a plurality of upper spring retaining tubes 41 and a plurality of lower spring retaining tubes are welded to the bottom end of the top cover 1 and the top end of the base 2 in the surrounding frame 3 respectively. After completion, the spring is sleeved on the lower spring retaining tube and fixedly welded to the top end of the base 2. Then, the top cover 1 with the surrounding frame 3 and the upper spring retaining tube 41 is placed on the spring group array 4, and the plurality of upper spring retaining tubes 41 are kept embedded in the plurality of springs respectively. Then, the springs are aligned with each other through the gap between the two surrounding frames 3. The top end of the spring and the bottom end of the top cover 1 are welded and fixed, and then the waterproof adhesive layer A5 is evenly brushed on the outer wall of the surrounding frame 3. After the waterproof adhesive layer A5 is cured, one end of the waterproof tape 6 is bonded to the outer sides of the two surrounding frames 3, and the other end is wrapped around the two surrounding frames 3 and covers the previously bonded ends. The waterproof tape 6 covers the gap between the two surrounding frames 3. Then, the waterproof adhesive layer B8 is brushed on the joint between the edge of the waterproof tape 6 and the outer wall of the surrounding frame 3. Finally, the locking bolt 8 is passed through the top cover 1 and screwed to the corresponding side connecting tube 7.

[0023] The waterproof tape 6 covers the gap between the waterproof adhesive layer A5 and the two surrounding frames 3, effectively closing any possible tiny gaps or joints to prevent water from penetrating. At the same time, the waterproof tape 6 also provides an additional physical barrier to enhance the water resistance of the overall structure. The waterproof adhesive layer B8 is applied to the joints between the edge of the waterproof tape 6 and the outer wall of the surrounding frame 3 and the joints between the two layers of waterproof tape 6, effectively filling the tiny gaps or imperfect fits that may exist at the joints of the waterproof tape 6, and also increasing the connection strength between the edge of the waterproof tape 6 and the surrounding frame 3. The waterproof adhesive layer A5 is able to resist external moisture and prevent it from penetrating into the interior of the vibration isolator through the gap between the surrounding frame 3 and the waterproof tape 6. One end of the waterproof tape 6 covers the other end to form a tighter and continuous waterproof barrier. This overlapping design can reduce the possibility of moisture penetrating through the joints at the ends of the waterproof tape 6.

[0024] The arrangement of the locking bolt 8 and the connecting tube 7 limits the distance between the top cover 1 and the base 2, effectively preventing the problem of loose connection between the top cover 1 and the spring due to the inertia generated when the spring group array 4 rebounds.
