Description

Technical Field

[0001] The invention relates to the technical field of cable laying assemblies, and in particular to a multi-lumen cable laying assembly for multiple lines of rail transit. Background Art

[0002] Multi-lumen cable laying components, also known as cable seals, are special products for sealing cables, optical fibers, etc. They are mainly designed to meet the requirements of airtightness, fire prevention, and waterproofing, while ensuring the integrity of the objects being passed through. They are mostly used for laying cables through walls in rail transit, underground pipe galleries, and other locations.

[0003] The patent with the publication number CN1330062C discloses a cable penetration device, comprising a tubular sleeve, one end of which has a component for fixing the device in a wall opening, and the other end of which has a thread that engages with a thread on a nut. The nut includes a supporting boss, and the device includes a rubber sleeve positioned in the tubular sleeve, and its outer diameter corresponds to the inner diameter of the tubular sleeve. The rubber sleeve is accommodated between the circular boss of the tubular sleeve and the supporting boss of the nut. The device also includes a plurality of module components, each of which includes a channel for accommodating a cable and is separated so that the channel can be accessed laterally. The modules together fill the opening of the elastic sleeve, and the opening has a shape that is adapted to the composite outer contour shape of the modules in a sealed combination.

[0004] Although the above technical solution can achieve the sealed penetration of the cable, in its actual use, during the pouring of the concrete wall, the sleeve is often placed in the concrete wall so that the sleeve and the concrete wall are integrated, and then the elastic rubber block is first knocked into the sleeve by hammering, and then the fastening component and the pressure plate are inserted, and then the elastic module is placed inside the elastic rubber block, and finally the fastening component is tightened to make the pressure plate squeeze the elastic rubber block to expand and achieve the sealing effect. In the above installation method, since the elastic rubber block needs to be installed with a tight fit, it is extremely inconvenient to knock and install, and it is easy to damage related components, causing difficulties in installation.

[0029] Technical effects and advantages of the present invention:

[0030] 1. The present invention cooperates with each other through the raised elastic sealing piece, the elastic rubber block, the first pressing plate, the second pressing plate, the fastening assembly, the elastic module, the elastic auxiliary pressing block, the extrusion block and the plug plate. Since the diameter of the elastic rubber block is smaller than the inner diameter of the sleeve, the elastic rubber block can be easily placed in the sleeve. Then, the first pressing plate and the second pressing plate are pre-tightened on the elastic rubber block by the forward-rotating bidirectional screw rod, so that the elastic rubber block expands and fits the inner wall of the sleeve, thereby achieving preliminary fixation of the elastic rubber block. The two are fixed only by a small friction force, preparing for subsequent fastening and fixation.

[0031] 2. The present invention realizes the extrusion of the elastic rubber block by tightening the fastening assembly twice through the mutual cooperation among the raised elastic sealing piece, the elastic rubber block, the first pressure plate, the second pressure plate, the fastening assembly, the elastic module, the elastic auxiliary pressure block, the extrusion block and the plug plate, so that the outer edge of the elastic rubber block expands outward and fits the inner wall of the sleeve, and fills the groove, so that the elastic rubber block and the sleeve are fixed by the friction between the two on the one hand, and on the other hand, due to the effect of filling the groove, the elastic rubber block, the sleeve and the wall can be limited, thereby further improving the fixing firmness of the elastic rubber block and the sleeve.

[0032] 3. The present invention cooperates with each other among the raised elastic sealing piece, the elastic rubber block, the first pressure plate, the second pressure plate, the fastening assembly, the elastic module, the elastic auxiliary pressure block, the extrusion block and the plug plate. When it is necessary to increase the extrusion force on the elastic module corresponding to a certain cable, the slider, the extrusion block and the elastic auxiliary pressure block are moved by rotating the bidirectional screw rod forward to apply a greater extrusion force to the elastic rubber block near the corresponding bidirectional screw rod, so that the elastic rubber block at the edge of the corresponding cable further expands and deforms, thereby increasing the extrusion force between the elastic module corresponding to the certain cable and the elastic rubber block, thereby further improving the sealing performance.

[0033] 4. The present invention reverses the bidirectional screw through the mutual cooperation among the raised elastic sealing piece, the elastic rubber block, the first pressure plate, the second pressure plate, the fastening assembly, the elastic module, the elastic auxiliary pressure block, the extrusion block and the plug plate. Due to the wedge-shaped cooperation between the wedge-shaped groove on the extrusion block and the wedge-shaped cooperation of the matching block, the extrusion block continues to move outward to pull the matching block toward the edge of the elastic rubber block. The movement of the matching block will drive the plug plate to move toward the edge of the elastic rubber block, thereby reducing the extrusion force between the plug plate and the elastic rubber block, thereby facilitating the adjustment of the length of a single cable extending out of the elastic module.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The present invention provides Figures 1 to 16 The multi-lumen cable laying assembly for multiple rail transit lines shown in the figure comprises a sleeve 1 having a plurality of first limiting grooves 101 arranged in an array on the side wall; the present invention provides the first limiting grooves 101 and, before pouring the wall, seals the first limiting grooves 101 with a raised elastic sealing member 2, thereby preventing concrete from entering the first limiting grooves 101 during pouring; on the other hand, since the raised elastic sealing member 2 has a protrusion, after pouring, a groove can be formed between the poured wall and the sleeve 1 by pulling out the raised elastic sealing member 2.

[0053] It also includes a raised elastic sealing member 2, which is placed in the first limiting groove 101 and is used to seal the first limiting groove 101, and after the concrete wall is poured, a groove is formed between the wall and the sleeve 1; the specific raised elastic sealing member 2 includes a sealing portion 201, and its outer wall is provided with a raised portion 202.

[0054] The elastic rubber block 3 is placed in the sleeve 1, and its diameter is smaller than the inner diameter of the sleeve 1. A square through hole 301 is opened in the center, and a plurality of annular hollow grooves 302 and square hollow grooves 303 are opened in the inner part. By opening the annular hollow grooves 302 and the square hollow grooves 303, the elastic rubber block 3 can be expanded quickly when the elastic rubber block 3 is squeezed.

[0055] Two groups of first pressure plates 4 are symmetrically arranged on both sides of the elastic rubber block 3, and each group of first pressure plates 4 has four first pressure plates 4, which are all located at the four corners of the square through hole 301; the present invention sets the first pressure plate 4 to limit the second pressure plate 5, thereby avoiding relative movement between the second pressure plates 5 located on the same side of the elastic rubber block 3.

[0056] The second pressing plate 5 is located between two adjacent first pressing plates 4, and its two ends are respectively limitedly plugged with the two adjacent first pressing plates 4; the present invention forms an annular structure connected end to end by limiting the second pressing plate 5 and the first pressing plate 4, and forms them into one by limiting the position, thereby avoiding relative movement between the first pressing plate 4 and the second pressing plate 5.

[0057] Specifically, the first pressing plate 4 is in an "H" shape.

[0058] Both ends of the bottom of the second pressing plate 5 are provided with "H"-shaped grooves for limited insertion and matching with the first pressing plate 4.

[0059] The fastening assembly 6 passes through the elastic rubber block 3 and the second pressure plate 5, and can enable the two second pressure plates 5 to clamp the elastic rubber block 3 and elastically deform the elastic rubber block 3. The present invention realizes the clamping of the second pressure plate 5 on the elastic rubber block 3 by setting the fastening assembly 6, thereby realizing the deformation and expansion of the elastic rubber block 3.

[0060] Specifically, Fig.11 As shown, the fastening assembly 6 includes a bidirectional screw rod 601 penetrating the second pressing plate 5 and the elastic rubber block 3, and a second limiting groove 602 is formed in an array on the peripheral side wall thereof.

[0061] The two sliders 603 are respectively threadedly connected to the two ends of the bidirectional screw rod 601 , and the side walls thereof are both limitedly slidably connected to the second pressing plate 5 through the limit plates 604 and the limit columns 605 .

[0062] The present invention twists the bidirectional screw 601, and since the slider 603 is in limited sliding connection with the second pressing plate 5, under the action of the thread, the slider 603 is moved closer to the elastic rubber block 3, and the second pressing plates 5 at both ends are pushed to squeeze the elastic rubber block 3, thereby clamping the elastic rubber block 3. The bidirectional screw 601 is twisted in the opposite direction, so that the sliders 603 are moved away from each other, and the clamping of the elastic rubber block 3 is released; for the convenience of understanding the present invention, the rotation direction of the bidirectional screw 601 that can make the two sliders 603 move closer to each other is defined as forward rotation, and the rotation direction of the bidirectional screw 601 that can make the two sliders 603 move away from each other is defined as reverse rotation.

[0063] The two arrays are provided with unidirectional rotation adjustment components 606, which are used to cooperate with the second limiting groove 602 to adjust the rotation direction of the bidirectional screw 601. The present invention adjusts the rotation direction of the bidirectional screw 601 by adjusting the unidirectional rotation adjustment component 606. When the bidirectional screw 601 rotates forward, the bidirectional screw 601 is limited to rotate only in the forward direction by adjusting the unidirectional rotation adjustment component 606.

[0064] like Fig.13 and 14As shown, the unidirectional rotation adjustment component 606 includes a limit rod 6061, one end of which is wedge-shaped and placed in the second limit groove 602, and the other end passes through the slider 603 and extends to the outside of the slider 603. The side wall of the limit rod 6061 located outside the slider 603 is provided with a first square limit block 6062 and a limit ring 6064, the outer sliding sleeve of the first square limit block 6062 is provided with a second square limit block 6063 connected to the slider 603, and the outer sleeve of the limit ring 6064 is provided with a rotating ring 6065, and the rotating ring 6065 is connected to the second square limit block 6063 through a tension spring. The present invention pulls the limit rod 6061, and the limit rod 6061 will slide outward under the action of the pulling force. At this time, the first square limit block 6062 slides out from the second square limit block 6063, and then the limit rod 6061 is rotated. The rotation of the limit rod 6061 will cause the wedge-shaped end face of the limit rod 6061 to rotate from one side to the other side. Due to the adjustment of the wedge-shaped end face, the rotation direction of the bidirectional screw rod 601 is adjusted.

[0065] like Figure 8 As shown, a plurality of elastic modules 7 are arranged in an array in the square through hole 301 . The present invention facilitates sealing between the elastic module 7 and the elastic rubber block 3 by setting the elastic rubber block 3 to be elastic.

[0066] The elastic auxiliary pressure block 8 passes through the second pressure plate 5 and is elastically connected to the second pressure plate 5, and is used to perform secondary compression on the elastic rubber block 3. The present invention sets an elastic auxiliary pressure block 8, and performs secondary compression on the elastic rubber block 3 by compressing the elastic auxiliary pressure block 8, thereby achieving sealing compression between the elastic module 7 and the elastic rubber block 3.

[0067] The extrusion block 12 is inserted into the top of the elastic auxiliary pressure block 8 and has a wedge-shaped groove 1201 on its top. The present invention sets the extrusion block 12 and rotates the bidirectional screw 601 forward to make the slider 603 press the extrusion block 12 downward. The downward pressure of the extrusion block 12 will push the elastic auxiliary pressure block 8 to move toward the elastic rubber block 3, thereby realizing secondary clamping.

[0068] A plurality of plug-in plates 13 are arranged on the inner wall of the square through hole 301 and correspond to the elastic module 7. The plug-in plates 13 are used to adjust the gap between the elastic rubber block 3 and the elastic module 7, so as to facilitate the adjustment of the cables in the single elastic module 7. The end of the plug-in plates 13 is plugged with a matching block 10 for matching with the wedge-shaped groove 1201. The present invention provides the plug-in plates 13, which are used to limit the elastic module 7 on the one hand, and on the other hand, cooperate with the matching block 10 and the wedge-shaped groove 1201 to press the elastic rubber block 3 outward, reduce the squeezing force of the elastic rubber block 3 on the elastic module 7, and thus facilitate the adjustment of the cables clamped in the elastic module 7.

[0069] Specifically, each elastic module 7 includes two elastic blocks 701, and a cable receiving groove 702 is opened on the opposite side. Multiple layers of cushion layers 703 are arranged in an array in the cable receiving groove 702, and adjacent cushion layers 703 on the same elastic block 701 are bonded to each other; the cushion layer 703 is set on the cylinder of the present invention, and the excess cushion layer 703 can be removed according to the cable diameter, so that the cable can be placed between the two elastic blocks 701.

[0070] The ends of the cushion layer 703 on the same elastic block 701 are all provided with grooves, and the grooves of the cushion layer 703 on the same elastic block 701 gradually extend from one side to the other side; by providing the grooves, the present invention facilitates the removal of excess cushion layer 703 when the cable is placed between the elastic blocks 701.

[0071] It also includes an observation hole 11, which is opened in the middle of the second pressure plate 5, and a countersunk hole 9 corresponding to the observation hole 11 is opened on the elastic rubber block 3. The present invention can facilitate observation of the deformation of the elastic rubber block 3 by setting the observation hole 11 and the countersunk hole 9.

[0072] Specifically, the elastic auxiliary pressure block 8 includes a pressure block body 801, and an elastic portion 802 is provided on one side of the pressure block body 801 close to the first pressure plate 4, and the elastic portion 802 is connected to the second pressure plate 5; by setting the elastic portion 802, when the extrusion block 12 reduces the extrusion force on the elastic auxiliary pressure block 8, the elastic auxiliary pressure block 8 will be reset under the action of the elastic force of the elastic portion 802.

[0073] The plug board 13 includes a board body 1301 , both ends of which are provided with limiting portions 1302 . The present invention facilitates docking with the matching block 10 by providing the limiting portions 1302 .

[0074] It also includes two pipe sleeve fixing rings 14, which are respectively placed at the two ends of the sleeve 1 and are threadedly connected to the sleeve 1. Rubber sealing pads 15 are provided on the opposite sides of the pipe sleeve fixing rings 14. The present invention fixes the two ends of the sleeve 1 by setting the pipe sleeve fixing rings 14, and at the same time, due to the setting of the rubber sealing pads 15, the sealing between the sleeve 1 and the wall is achieved.

[0075] The mating block 10 is provided with a plugging slot 1001 that matches with the limiting portion 1302 . The present invention realizes the plugging of the mating block 10 and the plugging board 13 by providing the plugging slot 1001 .

[0076] During the pouring of the concrete wall, the sleeve 1 with the raised elastic plugging piece 2 is placed into the concrete wall so that the sleeve 1 and the concrete wall are integrated. After solidification, the raised elastic plugging piece 2 is removed from the sleeve 1, so that a groove is formed between the poured wall and the sleeve 1. Then the bidirectional screw 601 is passed through the elastic rubber block 3, and then the first pressing plate 4 and the second pressing plate 5 are connected and inserted into the two ends of the bidirectional screw 601, and then the slider 603 is connected to the bidirectional screw 601, and the unidirectional rotation adjustment component 606 is adjusted to a position where the bidirectional screw 601 can rotate in the forward direction, and then the slider 603 is grasped and the bidirectional screw 601 is twisted. , because the slider 603 is grasped and limited, the two sliders 603 are close to each other and penetrate into their corresponding limiting columns 605, thereby realizing the limiting of the slider 603; then the elastic rubber block 3 is placed in the sleeve 1. Since the diameter of the elastic rubber block 3 is smaller than the inner diameter of the sleeve 1, the elastic rubber block 3 can be easily placed in the sleeve 1, and then the first pressing plate 4 and the second pressing plate 5 are pre-pressed on the elastic rubber block 3 by the forward rotating bidirectional screw rod 601, so that the elastic rubber block 3 expands and fits the inner wall of the sleeve 1, realizing the preliminary fixation of the elastic rubber block 3, and the two are fixed by friction, preparing for further fixation later.

[0077] Then insert the plug plate 13 into the inner wall of the square through hole 301, and then remove the cushion layer 703 of the elastic module 7 according to the cable diameter, so that the elastic module 7 adapts to the cable, and then connect the elastic module 7 to the cable, and then put the elastic module 7 that clamps the cable into the square through hole 301, so as to complete the placement of the elastic module 7 that clamps the cable. It should be emphasized in the present invention that the elastic module 7 can be easily inserted into the elastic rubber block 3 when the elastic rubber block 3 is pre-compressed, that is, the size of the elastic module 7 is smaller than the size of the square through hole 301 after the elastic rubber block 3 is pre-compressed.

[0078] Then the fastening component 6 is tightened for the second time. At this time, since the unidirectional rotation adjustment component 606 is in a position where the bidirectional screw rod 601 can be rotated in the forward direction, the bidirectional screw rod 601 can be rotated forward to squeeze the elastic rubber block 3, so that the outer edge of the elastic rubber block 3 expands outward and fits the inner wall of the sleeve 1, and fills the groove, so that the elastic rubber block 3 and the sleeve 1 are fixed on the one hand by the friction between the two, and on the other hand, due to the effect of filling the groove, the elastic rubber block 3, the sleeve 1 and the wall can be limited, thereby improving the fixing firmness of the elastic rubber block 3 and the sleeve 1; at the same time, the extrusion can make the inner edge of the elastic rubber block 3 expand inward, thereby squeezing the elastic module 7, thereby achieving sealing between the elastic module 7 and the elastic rubber block 3.

[0079] Due to the different diameters of some cables, in order to increase the sealing firmness between the elastic module 7 of a certain cable and the elastic rubber block 3, when it is necessary to increase the extrusion force on the elastic module 7 corresponding to a certain cable, the two unidirectional rotation adjustment components 606 on the bidirectional screw rod 601 corresponding to the cable are adjusted to make the unidirectional rotation adjustment component 606 be in a position capable of reversing the bidirectional screw rod 601, and then the bidirectional screw rod 601 is reversed to make the two sliders 603 move away from each other. At this time, although the sliders 603 on one of the bidirectional screw rods 601 on the corresponding second pressure plate 5 move away from each other, since there is still a slider 603 on the other bidirectional screw rod 601 pressing the second pressure plate 5, the second pressure plate 5 will not be loosened. When the two sliders 603 moving away from each other move away to the top of the extrusion block 12, the extrusion block 12 and the elastic auxiliary The pressure block 8 is plugged in, and then the two unidirectional rotation adjustment components 606 on the bidirectional screw rod 601 corresponding to the cable are adjusted to make the unidirectional rotation adjustment component 606 in a position that can make the bidirectional screw rod 601 rotate forward, and then the bidirectional screw rod 601 rotates forward to make the two sliders 603 approach each other. After overcoming the elastic force of the elastic part 802 on the elastic auxiliary pressure block 8, the sliders 603 approach each other and push the extrusion block 12 to approach the elastic rubber block 3. The movement of the extrusion block 12 will push the elastic auxiliary pressure block 8 to approach the elastic rubber block 3. The movement of the elastic auxiliary pressure block 8 will apply a greater extrusion force to the elastic rubber block 3 at the edge of the corresponding cable, causing the elastic rubber block 3 at the edge of the corresponding cable to further expand and deform, thereby increasing the extrusion force between the elastic module 7 and the elastic rubber block 3 corresponding to the cable, and further improving the sealing.

[0080] When it is necessary to adjust the length of a single cable extending out of the elastic module 7, the unidirectional rotation adjustment component 606 on the bidirectional screw rod 601 corresponding to the upper and lower sides of the cable is adjusted to enable the bidirectional screw rod 601 to be reversed, and then the bidirectional screw rod 601 is reversed, so that the two sliders 603 on the same bidirectional screw rod 601 move away from each other to a position where the extrusion block 12 is no longer squeezed, and then restored to the initial position under the elastic force of the elastic auxiliary pressure block 8, thereby reducing the extrusion force on the corresponding elastic module 7, and then the extrusion block 12 is pushed to slide to one side, so that the extrusion block 12 is misaligned with the elastic auxiliary pressure block 8, and at the same time, the extrusion block 12 is misaligned with the limit plate 604 and the limit column 605, and then the extrusion block 12 is pulled to move upward, and the extrusion block 12 moves upward to the side of the limit plate 604 away from the elastic rubber block 3, and then the extrusion block 12 is pushed. Slide toward the center of the limiting column 605 so that the extrusion block 12 is on the side of the limiting plate 604 away from the elastic rubber block 3, and the two are facing each other at this time, then the matching block 10 is connected with the plugging plate 13, and then the bidirectional screw rod 601 is twisted in the opposite direction to make the wedge-shaped groove 1201 on the extrusion block 12 conflict with the matching block 10 to form a matching connection, and then the bidirectional screw rod 601 is continued to be twisted in the opposite direction, thereby driving the extrusion block 12 to move in the direction away from the elastic rubber block 3. Due to the wedge-shaped fit between the wedge-shaped groove 1201 on the extrusion block 12 and the matching block 10, the outward movement of the extrusion block 12 will cause the matching block 10 to move toward the side wall of the elastic rubber block 3, and the movement of the matching block 10 will drive the plugging plate 13 to move toward the side wall of the elastic rubber block 3, thereby reducing the extrusion force between the plugging plate 13 and the elastic rubber block 3, thereby facilitating the adjustment of the length of a single cable extending out of the elastic module 7.
