Abstract
Description
Technical Field
[0001] The present application relates to the field of cable trenches, and in particular to a position-limiting and noise-reducing cable trench steel track. Background Art
[0002] In places with dense cables such as substations, cables are generally laid by digging cable trenches, which can effectively protect the cables and facilitate the maintenance or replacement of the cables in the future.
[0003] At present, after the overall concrete curing of the cable trench is completed, a cover plate will be placed on the track of the cable trench to cover the cable trench. On the one hand, it can prevent external debris from falling into the cable trench and ensure that the cables in the cable trench are in a relatively stable working environment. On the other hand, when the cable trench is covered by all the cover plates, the inspection vehicle can travel on the cover plates to cross the cable trench or walk along the length of the cable trench.
[0004] However, the cover plate will inevitably deform during transportation, storage or installation, which will cause the cover plate to not fit completely with the track of the cable trench. In this way, when the inspection vehicle or inspection personnel walk on the cover plate, the cover plate will become loose and collide with the track, generating noise and posing certain safety hazards. Summary of the Invention
[0005] In order to improve the problem of poor flatness and noise generation after the cover plate is installed on the existing track, the present application provides a limited noise reduction cable trench steel track.
[0006] This application provides a position-limiting and noise-reducing cable trench steel track, which adopts the following technical solutions:
[0007] A position-limiting and noise-reducing cable trench steel track comprises a track body, wherein the track body comprises a fixing portion and a receiving portion, wherein the fixing portion is in an inverted U shape and the receiving portion is straight and connected to the lower portion of the outer wall of the fixing portion;
[0008] The fixing part and the receiving part are both welded to the support pad of the cable trench. The top height of the receiving part is lower than the top height of the fixing part. A silicone pad is provided on the receiving part. The silicone pad and the receiving part are connected by a number of self-tapping screws. A number of cover plates are placed on the silicone pad in sequence.
[0009] By adopting the above technical solution, after the positions of the fixing part and the receiving part on the support pad are adjusted, the fixing part and the receiving part are welded so that they are fixed on the support pad and the multiple track bodies in a cable trench are in a flat state. Then, a silicone pad that matches the receiving part is placed on the receiving part, and the silicone pad is fixed with self-tapping screws. In this way, after the cover plate is placed in the track body, the cover plate will contact the silicone pad, and the silicone pad can produce a certain amount of deformation, thereby improving the overall flatness of the cable trench, reducing the noise generated by the collision between the cover plate and the track body, and improving the construction quality. Moreover, the inspection personnel or inspection vehicles can walk on the cover plate more smoothly without generating noise due to the poor flatness of the track body.
[0010] Optionally, the silicone pad is provided with a plurality of countersunk holes, and the head of the self-tapping screw passes through the silicone pad and then drills into the interior of the receiving portion, and the tail of the self-tapping screw is located in the countersunk hole.
[0011] By adopting the above technical solution, the self-tapping screws can be prevented from directly contacting the cover plate, thereby further reducing noise. In addition, the self-tapping screws are arranged on the silicone pad at intervals of 40-45 cm to ensure that the silicone pad can be fixed on the receiving part in a flat state without arching, thereby improving the fit between the silicone pad and the cover plate, and enabling the cover plate to be laid flatly on a pair of track bodies in the cable trench. Moreover, the tail of the self-tapping screw is located in the countersunk hole and will not collide with the cover plate, thereby further reducing the collision between the cover plate and hard objects, thereby improving the noise reduction effect and ensuring the flatness of the cover plate on the silicone pad. In this way, when patrol personnel or patrol vehicles walk on the cover plate, they can be more stable and no safety accidents will occur. By suppressing noise, the attention of patrol personnel can be ensured not to be affected by noise, thereby improving patrol efficiency and effectiveness.
[0012] Optionally, a partition is provided between the silicone pad and the receiving portion, the partition is in an inverted L-shape, the vertical end of the partition is connected to the receiving portion, and the horizontal end of the partition is parallel to the receiving portion and extends into the fixing portion.
[0013] By adopting the above technical solution, the silicone pad can be fixed after the self-tapping screw passes through the partition, and the thickness of the partition is smaller than the thickness of the receiving part. In this way, the difficulty of rotating the self-tapping screw can be reduced, ensuring that the self-tapping screw can be quickly screwed into the receiving part during installation, thereby realizing the rapid laying and fixing of the silicone pad, avoiding the loosening of the self-tapping screw in the later stage, and ensuring that the silicone pad can be reliably fixed on the track body.
[0014] Optionally, there is a distance between the transverse end of the partition and the receiving portion, and the self-tapping screw passes through the transverse end of the partition and is screwed into the receiving portion.
[0015] By adopting the above technical solution, the self-tapping screw will continue to be screwed into the receiving part after being screwed into the relatively thin partition. The self-tapping screw will be in a threaded connection with the partition and the receiving part, ensuring that the silicone pad can be reliably fixed, and can improve the screw-in efficiency of the self-tapping screw. It can also prevent the self-tapping screw from being damaged during the rotation process to a certain extent, which will reduce the durability of the self-tapping screw and is not conducive to the continuous fixation of the silicone pad by the self-tapping screw.
[0016] Optionally, a pair of clamping plates are provided between the lateral ends of the partition and the receiving portion, and the pair of clamping plates are symmetrically arranged on both sides of the self-tapping screws, and the clamping plates are used to support the partition.
[0017] By adopting the above technical solution, a pair of card plates can provide support force for the partition, ensuring that the partition can remain flat after the self-tapping screws lock the silicone pad, thereby ensuring that the silicone pad and the cover plate arranged on the silicone pad can have a high degree of flatness; and the card plates can, to a certain extent, limit and guide the screw-in direction of the self-tapping screws, ensuring that the self-tapping bolts can be rotated downward in a vertical state, thereby improving the locking effect of the silicone pad.
[0018] Optionally, the outer wall of the vertical end of the partition is flush with the outer wall of the receiving portion, and there is a distance between the horizontal end of the partition and the inner wall of the fixing portion after the horizontal end of the partition passes through the interior of the fixing portion.
[0019] By adopting the above technical solution, after pouring is completed, the outer wall of the vertical end of the partition is flush with the outer wall of the receiving part, and both are located on the inner wall of the cable trench, which improves the flatness of the inner wall of the cable trench and ensures that the cable will not interfere with the outer wall of the vertical end of the partition or the outer wall of the receiving part during the laying process or produce mutual squeezing and friction, thereby avoiding damage to the cable; the horizontal end of the partition is convex in shape, thus ensuring that the horizontal end of the partition can be inserted into the interior of the fixed part without causing the fixed part to be cut off, and then after concrete is poured into the interior of the fixed part, the partition located inside the fixed part can cooperate with the concrete to enhance the tensile strength of the track body, thereby further improving the stability of the overall structure.
[0020] Optionally, an indicator needle is provided between the pair of card plates, one end of the indicator needle is located below the partition plate, and the other end of the indicator needle passes through the partition plate and the silicone pad in sequence and extends to the top of the countersunk hole;
[0021] The bottom of the self-tapping screw is provided with an accommodating hole, and the indicator needle is inserted into the accommodating hole.
[0022] By adopting the above technical solution, before welding the partition, the indicator needle is placed between a pair of clamping plates, and the indicator needle is passed through the partition and the silicone pad, so that the indicator needle is in a state of active connection, that is, the indicator needle can be displaced under the drive of external force, and maintain the current state after the external force is removed. Since the other end of the indicator needle is located above the countersunk hole, it can play a role in indicating the position of the countersunk hole, which is convenient for the installer to quickly find the installation point of the self-tapping screw and improve the screw-in efficiency of the self-tapping screw; further, since the bottom of the self-tapping screw is provided with a accommodating hole, the precise positioning of the self-tapping screw is achieved in the process of inserting the indicator needle into the accommodating hole, and since the indicator needle will punch the holes left on the silicone pad and the partition during the penetration process, the self-tapping screw can more easily pass through the partition and be screwed into the receiving part.
[0023] Optionally, the depth of the accommodating hole is smaller than the length of the indicator needle, and a pair of limiting plates made of rubber material are provided on the top of the silicone pad. A pull rope is passed through the silicone pad, one end of the pull rope is connected to the bottom of the limiting plate, and the other end of the pull rope is connected to the lower part of the indicator needle after passing through the silicone pad, the partition and the card plate.
[0024] By adopting the above technical solution, in the process of the self-tapping screw rotating downward, since the depth of the accommodating hole is less than the length of the indicator needle, the self-tapping screw will continue to rotate downward after the indicator needle is fully entered into the accommodating hole, thereby forming a downward pushing effect on the indicator needle. Since the indicator needle and the limit plate are connected by a pull rope, the limit plate will also move downward at the same time as the indicator needle under the pulling action of the pull rope, thereby forming a downward pressing effect on the silicone pad. The pull rope can be an elastic rope. In this way, after the pull rope is tightened, it can generate sufficient tension on the limit plate, and the limit plate only ensures the downward pressing effect on the silicone pad through a slight displacement, ensuring that the silicone pad remains in a state of being in contact with the partition, avoiding direct contact of the cover plate with the receiving part to generate noise; furthermore, space for the pull rope to move is reserved between the pull rope and the silicone pad and between the pull rope and the partition, avoiding repeated friction between the partition and the silicone pad after the pull rope is subjected to the tension transmitted by the indicator needle, causing the pull rope to break or causing damage to the partition and the silicone pad.
[0025] Optionally, a rectangular tube is provided on both sides of the bottom of the cover plate, and the rectangular tube is pressed on the top of the limiting plate.
[0026] By adopting the above technical solution, the rectangular tube can maintain a fit with both the receiving part and the fixing part, thereby improving the firmness and stability of the installation of the cover plate between a pair of rail bodies, and avoiding noise generated by collision between the cover plate and the receiving part when patrol personnel or vehicles walk on the cover plate.
[0027] Optionally, a pouring hole is provided on a side of the fixing portion facing away from the receiving portion, and concrete enters the interior of the fixing portion through the pouring hole and solidifies.
[0028] By adopting the above technical solution, after the rail body is welded on the support pad, the formwork is set up for pouring to realize the overall formation of the cable trench. During the pouring process, concrete will enter the interior of the fixed part through the pouring hole, thereby improving the overall strength.
[0029] In summary, this application has the following beneficial effects:
[0030] 1. By placing a silicone pad that matches the receiving part on the receiving part and then fixing the silicone pad with self-tapping screws, after the cover is placed in the track body, the cover will only contact the softer silicone pad, so that the cover can be laid more flatly in the cable trench and avoid contact between the cover and other hard objects, thus avoiding the cover from generating loud noise due to collision and improving the construction quality.
[0031] 2. By setting countersunk holes on the silicone pad and ensuring that the top of the self-tapping screw does not protrude above the countersunk hole, collision between the cover plate and the self-tapping screw is avoided, ensuring that the self-tapping screw is securely locked and the silicone pad is securely installed, while further reducing noise.
[0032] 3. By inserting an indicator needle in the countersunk hole, it can indicate the screw-in point of the self-tapping screw. Furthermore, an axially extending accommodating hole is provided at the bottom of the self-tapping screw, and limit plates are provided on both sides of the countersunk hole, and the limit plates and the indicator needle are connected by a pull rope. In this way, under the continuous downward rotation of the self-tapping screw, the indicator needle will drive the pull rope to move downward and tighten, thereby applying downward pressure to the silicone pad through the limit plate to ensure that the silicone pad is securely installed.

[0039] The following is combined with Figure 1-5 This application is described in further detail.
[0040] Figure 1 is a schematic three-dimensional diagram of this application, Figure 2 This is a schematic diagram of the internal state of this application. Figure 1 and Figure 2 , a limited noise reduction cable trench steel track, including a track body 1, a pair of track bodies 1 are respectively arranged on both sides of the cable trench, the track body 1 includes a fixing portion 11 and a receiving portion 12, the fixing portion 11 is inverted U-shaped, the receiving portion 12 is straight and connected to the lower portion of the outer wall of the fixing portion 11, the fixing portion 11 and the receiving portion 12 can be welded to each other or can be an integrally formed structure, the top of the fixing portion 11 is flush with the top of the cable trench, the top of the receiving portion 12 is located inside the cable trench, the fixing portion 11 plays a role of overall fixing, the receiving portion 12 is used to receive the cover plate 5, when the cover plate 5 is placed on the receiving portion 12, the top of the cover plate 5 is flush with the top of the fixing portion 11.
[0041] Several support pads 2 for supporting the track body 1 are provided on both sides of the top of the cable trench. The track body 1 is placed on the support pads 2, and then the height of the support pads 2 is adjusted (the height adjustment method of the support pads 2 is the existing technology, so the specific structure of the support pads 2 is not explained) to ensure that multiple track bodies 1 are at the same height. Then the fixing part 11 and the receiving part 12 of the track body 1 are welded to the support pads 2, and then the two adjacent track bodies 1 are welded. Finally, the formwork is set up, and the support pads 2, the fixing part 11 and the receiving part 12 are poured. After the pouring is completed, the support pads 2 are located inside the concrete, and the top of the fixing part 11, the side where the fixing part 11 and the receiving part 12 are connected, and the top of the receiving part 12 are exposed, and the rest of the parts are also located inside the concrete. In this way, the laying of the track body 1 in the cable trench is completed.
[0042] Since a pouring hole 110 is provided on the side of the fixing part 11 that is opposite to the receiving part 12, during the pouring process of the rail body 1, concrete will enter the interior of the fixing part 11 through the pouring hole 110, thereby improving the fixing effect of the fixing part 11 and ensuring that the fixing part 11 always maintains the height of the support plate 2 after adjustment.
[0043] See also Figure 2 and Figure 4 An inverted L-shaped partition 6 is provided on the top of the receiving portion 12. The vertical end face of the partition 6 is flush with the end face of the receiving portion 12. There is a distance between the horizontal end of the partition 6 and the receiving portion 12. The horizontal end face of the partition 6 is delayed to the interior of the fixing portion 11 (an opening is provided on the side where the fixing portion 11 is connected to the receiving portion 12, and the horizontal end of the partition 6 is convex. The side with the smaller outer diameter of the partition 6 is inserted into the fixing portion 11 through the opening). In the process of concrete entering the fixing portion 11 through the pouring hole 110, the tensile strength of the concrete is improved, ensuring that the fixing portion 11 and the receiving portion 12 are in a fixed position. A silicone pad 3 is provided on the top of the partition 6. The silicone pad 3 is laid along the length direction of the support portion. A number of countersunk holes 30 are provided at intervals on the top of the silicone pad 3. The distance between two adjacent countersunk holes 30 is 40-45 cm. A self-tapping screw 4 is screwed into the countersunk hole 30. The head of the self-tapping screw 4 passes through the silicone pad 3 and the partition 6 and then drills into the interior of the receiving portion 12. The tail of the self-tapping screw 4 is located in the countersunk hole 30. In this way, the self-tapping screw 4 can be threadedly connected with the silicone pad 3, the partition 6 and the receiving portion 12, ensuring that the self-tapping screw 4 will not loosen, thereby ensuring that the silicone pad 3 can be reliably assembled on the top of the receiving portion 12 without arching. In this way, the self-tapping screw 4 can be threadedly connected with the silicone pad 3, the partition 6 and the receiving portion 12, thereby ensuring that the self-tapping screw 4 will not loosen, thereby ensuring that the silicone pad 3 can be reliably assembled on the top of the receiving portion 12 without arching. After the cover plate 5 is placed on the top of the silicone pad 3, the pressing effect of the cover plate 5 on the silicone pad 3 will cause the silicone pad 3 to produce a certain elastic deformation. In this way, when the inspection personnel or the inspection vehicle walk on the cover plate 5, the silicone pad 3 will form a buffering effect on the cover plate 5, reducing the swing amplitude of the cover plate 5, thereby effectively reducing the noise; moreover, when the flatness of the cover plate 5 is poor, the deformation of the silicone pad 3 can make up for the curved part of the cover plate 5, which can effectively reduce the large-scale prying of the curved cover plate 5 after being stepped on by the inspection personnel, thereby reducing the impact noise generated when the cover plate 5 is reset after being pried, and improving the flatness of the cover plate 5 laid on the track body 1.
[0044] Figure 3 This is a reference diagram of the cover plate 5 and the self-tapping bolts in the unassembled state in this application. Figure 4 This is a schematic diagram of the internal structure of the cover plate 5 and the self-tapping bolts in the present application when not assembled. Figure 3 and Figure 4Furthermore, a pair of clamping plates 7 are provided between the partition 6 and the receiving portion 12. A plurality of indicator pins 8 are provided between the pair of clamping plates 7. The plurality of indicator pins 8 correspond one-to-one to the plurality of countersunk holes 30. One end of the indicator pin 8 is located below the partition 6. The other end of the indicator pin 8 passes through the partition 6 and the silicone pad 3 in sequence and extends above the countersunk hole 30. A pair of rubber-made limiting plates 9 are symmetrically provided on top of the silicone pad 3 and on both sides of the countersunk hole 30. The limiting plates 9 and the indicator pins 8 are connected by a pull rope 90. One end of the pull rope 90 is fixed to the bottom of the limiting plate 9. The other end of the pull rope 90 passes through the silicone pad 3, the partition 6, and the clamping plates 7 and is connected to the lower portion of the indicator pin 8. At this time, the indicator pin 8 is suspended between the partition 6 and the receiving portion 12 due to the friction and clamping action of the silicone pad 3, with the lower portion of the indicator pin 8 close to the bottom of the partition 6. A waist hole 70 is provided on the clamping plate 7, and the pull rope 90 is inserted through the waist hole 70 and connected to the indicator needle 8. The waist hole 70 extends in the vertical direction. In this way, the pull rope 90 can move up and down in the waist hole 70, so that after the indicator needle 8 is pressed down, the pull rope 90 can be displaced and be in a tensioned state.
[0045] Figure 5 It is a schematic three-dimensional diagram of the self-tapping screw 4 in this application. Figure 5 Combined with Figure 4 , a receiving hole 40 is provided at the bottom of the self-tapping screw 4, and the depth of the receiving hole 40 is less than the length of the indicator needle 8. In this way, when the self-tapping screw 4 is rotated downward, the receiving hole 40 will be sleeved on the outside of the indicator needle 8, and as the self-tapping screw 4 continues to rotate downward, the top of the indicator needle 8 will touch the top of the receiving hole 40. At this time, the self-tapping screw 4 has not yet been screwed into the receiving portion 12, and the pair of pull ropes 90 are both in a tensioned state. If the self-tapping screw 4 is continued to be rotated, the self-tapping screw 4 will be screwed into the receiving plate and will bring The pull rope 90 is pulled downward, so that the pull rope 90 has an obvious and continuous downward pulling force on the limit plate 9, which will make the silicone pad 3 reliably fit with the top of the partition 6. That is to say, in the process of inserting the indicator needle 8 into the self-tapping screw 4, the self-tapping screw 4 will pull the pull rope 90 downward, thereby improving the installation firmness of the silicone pad 3 and ensuring that the silicone pad 3 is in a straight state. Moreover, the indicator needle 8 extends to the top of the countersunk hole 30, which can play the role of indicating the screw-in point of the self-tapping screw 4, thereby facilitating the rapid screwing in of the self-tapping screw 4.
[0046] When the self-tapping screw 4 is screwed into the receiving portion 12 and the limiting plate 9 is reliably pressed against the silicone pad 3, the cover plate 5 is placed in the cable trench. A pair of rectangular tubes 50 are symmetrically provided at the bottom of the cover plate 5. The rectangular tubes 50 extend along the length direction of the cover plate 5. The pair of rectangular tubes 50 are respectively placed above the pair of silicone pads 3, and the top of the silicone pad 3 and the bottom of the rectangular tube 50 are separated by the limiting plate 9. The width of the rectangular tube 50 is consistent with the width of the silicone pad 3, and the length of the rectangular tube 50 is consistent with the length of the silicone pad 3. When several limiting plates on a silicone pad 3 are After 9 contacts the bottom of the rectangular tube 50, the rectangular tube 50 is placed in place and the cover plate 5 is installed. At this time, the distance between the bottom of the rectangular tube 50 and the tail of the self-tapping screw 4 is not less than the thickness of the limit plate 9. In this way, it can be ensured that there is enough distance between the self-tapping screw 4 and the rectangular tube 50 for the deformation of the silicone pad 3 and the limit plate 9, thereby ensuring that after the silicone pad 3 and the limit plate 9 are deformed, the rectangular tube 50 will not hit the self-tapping screw 4, which minimizes the noise generated by the cover plate 5 due to hitting foreign objects and improves the overall noise reduction effect.
[0047] The working process of the present application when in use is as follows: first, the fixing portion 11 and the receiving portion 12 of the track body 1 are placed on the supporting pad 2, and then the height of the supporting pad 2 is adjusted so that the track bodies 1 on both sides of the cable trench are in the same horizontal state, and then the track body 1 support pad 2 and the track body 1 are welded to complete the positioning operation of the track body 1;
[0048] After the track body 1 is positioned, the card plate 7 and the partition 6 are placed on the top of the receiving portion 12, and a pouring hole 110 is opened on the side of the fixing portion 11 facing away from the receiving portion 12. An opening is opened on the side where the fixing portion 11 and the receiving portion 12 are connected. Then, the horizontal end of the partition 6 is inserted into the interior of the fixing portion 11, and then the track body 1 and the support pad 2 are integrally poured with concrete, so that a fixed-size whole is formed between the track body 1 and the support pad 2. At this time, the part of the partition 6 located above the receiving portion 12 is exposed, and then the silicone pad 3 and the limit plate 9 are placed on the top of the partition 6. , and insert the pull rope 90 used to connect the limit plate 9 and the indicator needle 8 into the silicone pad 3, the partition plate 6 and the card plate 7, then screw in the self-tapping screw 4, and insert the self-tapping screw 4 into the outside of the indicator needle 8. The self-tapping bolt presses the indicator needle 8 to complete the pulling down of the pull rope 90, and then the locking of the self-tapping screw 4 and the downward pressure of the limit plate 9 ensure that the silicone pad 3 can be laid reliably, and with the auxiliary action of the limit plate 9, provide soft support for the cover plate 5 and the rectangular tube 50 at the bottom of the cover plate 5, avoid the cover plate 5 and other components from expanding and generating noise, and have a good noise reduction effect.
[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
