Description

Technical Field

[0001] The invention belongs to the technical field of cable laying, in particular to a double telescopic pressure rod for adjusting a cable in a tunnel in a serpentine shape. Background Art

[0002] The importance of the power tunnel system, as the backbone of the modern power industry power supply network, is self-evident. With the acceleration of urbanization and the growing demand for electricity, power cables, with their advantages of high efficiency, beauty, and small footprint, play an increasingly critical role in power grid construction. In the process of laying high-voltage cables, especially for ultra-high voltage, long-length, and large-section cable lines laid in tunnels, the challenges faced are particularly severe. Such cables not only carry huge power transmission tasks, but their huge volume and weight also put forward higher requirements for construction. Among them, the serpentine laying technology of cables is a crucial process measure. This technology pre-lays the cables in a wavy or serpentine manner, reserves sufficient expansion space, and absorbs the thermal expansion and contraction effects of cables caused by factors such as ambient temperature changes and load fluctuations in a natural and gentle way, thereby effectively protecting the cable body and its accessories from mechanical stress damage caused by length changes, ensuring the long-term stable operation of the cable line;

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figures 1 to 7 As shown, the present invention provides a double telescopic pressure rod for adjusting a cable snake in a tunnel, comprising a bottom plate 1, a fixing groove 2 is provided on the top of the bottom plate 1, and a support block 3 is slidably connected inside the fixing groove 2;

[0031] An adjustment mechanism is arranged at the top of the support block 3, and the adjustment mechanism includes a fixed shell 4, which is fixedly connected to the top of the support block 3. There are two fixed shells 4, and the interiors of the two fixed shells 4 are slidably connected with a slide bar 5, and a compression rod 1 6 and a compression rod 2 7 are arranged on one side of the top of the surface of the slide bar 5. A driving assembly 14 is fixedly installed on the opposite side of the top of the fixed shell 4, and a screw rod 15 is fixedly installed on the output end of the driving assembly 14. A threaded block 16 is threadedly connected to the surface of the screw rod 15, and the opposite side of the threaded block 16 is fixedly connected to the opposite side of the slide bar 5;

[0032] The adjusting mechanism is arranged in the middle of the top of the base plate 1, and the adjusting mechanism includes a fixed box 10, which is fixedly connected to the middle of the top of the base plate 1, and two gears 11 are rotated on one side of the interior of the fixed box 10, and a push rod 12 is fixedly installed on one side of the surface of the gear 11, and a mounting plate 8 is fixedly installed on the side of the fixed shell 4 close to the push rod 12, and a slide groove 9 is opened on the surface of the mounting plate 8, and a sliding block 13 located inside the slide groove 9 is fixedly installed on one side of the push rod 12, and a motor 17 is fixedly installed on the side of the fixed box 10 away from the push rod 12, and the output end of the motor 17 extends to the interior of the fixed box 10 and is fixedly connected to the gear 11.

[0033] The above scheme is adopted: the operator installs the equipment at the preset position, and then the motor 17 can be driven to rotate the gear 11. Because the two gears 11 are meshed with each other, the gear 11 will drive the other gear 11 to rotate, and then the two gears 11 will drive the two push rods 12 to rotate, and then the push rod 12 will drive the sliding block 13 to move inside the sliding groove 9. During the movement of the sliding block 13, the push rod 12 will push the mounting plate 18 and the fixed shell 4 to move relative to or towards each other, and then the fixed shell 4 will drive the support block 3 to move inside the fixed groove 2, and then the mounting plate 18 will drive the sliding rod 15, the compression rod 16 and the compression rod 27 to move, and then the compression rod 16 and the compression rod 27 can be moved to the specified position, and finally the compression rod 16 and the compression rod 27 can be driven by the motor 17 to move relative to or relative to each other, so that the equipment can adjust the distance between the compression rod 16 and the compression rod 27 according to the bending requirements of the cable, thereby improving the adaptability and flexibility of the equipment;

[0034] After the compression rod 1 6 and the compression rod 2 7 are adjusted, the cable can be allowed to enter between the compression rod 1 6 and the compression rod 2 7, and then the driving assembly 14 can be driven to rotate the screw rod 15. Since the screw rod 15 is threadedly connected to the threaded block 16, when the screw rod 15 rotates, the threaded block 16 will move on the surface of the screw rod 15, and then the threaded block 16 will drive the sliding rod 1 5 and the compression rod 1 6 to move upward, while the other threaded block 16 will drive the sliding rod 1 5 and the compression rod 2 7 to descend, and then the compression rod 1 6 and the compression rod 2 7 will both contact the top and bottom ends of the cable surface, and then the shape of the cable is adjusted by extrusion to make it close to the expected serpentine bending state. After the adjustment is completed, the corresponding clamp can be used to fix the shape of the cable to prevent it from moving or deforming during use.

[0035] like Figure 5 and Figure 6As shown, it also includes: a control mechanism, which is arranged on one side of the surface of the bottom plate 1, and the control mechanism includes a connecting rod 18, the connecting rod 18 is fixedly connected to one side of the surface of the bottom plate 1, the surface of the connecting rod 18 is movably sleeved with a square shell 19, and a connecting rod 20 is fixedly installed on the opposite side of the connecting rod 18, and a mounting shell 21 is fixedly installed on the top of the square shell 19, and the interior of the mounting shell 21 is rotatably connected to a transmission gear 22, and the number of the transmission gears 22 is two, and the surfaces of the two transmission gears 22 are rotatably connected to a toothed belt 23, and the mounting shell 21 is fixedly installed on the top of the square shell 19. A motor 24 is fixedly installed on the top of the mounting shell 21, and the output end of the motor 24 extends to the inside of the mounting shell 21 and is fixedly connected to the top of the transmission gear 22. A square plate 25 is fixedly installed on the side opposite to the square shell 19, and a slide bar 26 is fixedly installed on the side of the square plate 25 away from the surface of the bottom plate 1. The surface of the slide bar 26 is slidably connected to a slide bar 27 located at the top of the connecting rod 20. A connecting plate 33 is fixedly installed on the side of the toothed belt 23 close to the surface of the slide bar 27, and the other end of the connecting plate 33 is fixedly connected to the surface of the slide bar 27.

[0036] The above scheme is adopted: through the design of the control mechanism, after the position adjustment of the compression rod 1 6 and the compression rod 2 7 is completed, the motor 2 24 can be driven to rotate the transmission gear 22. Since the surface transmission of the two transmission gears 22 is connected with the toothed belt 23, the transmission gear 22 will drive the toothed belt 23 and the other transmission gear 22 to rotate, and then the toothed belt 23 will drive the connecting plate 33 to move, and then the connecting plate 33 will drive the slider 27 to move on the surface of the slide rod 2 26, and the slider 27 will drive the connecting rod 20 to move, and the connecting rod 20 will pull the connecting rod 1 18 to move, and the connecting rod 1 18 will pull the bottom plate 1 to move, and then the bottom plate 1 will drive the compression rod 1 6 and the compression rod 2 7 to move, and then the cable will enter between the compression rod 1 6 and the compression rod 2 7, and finally the connecting plate 33 will pull the connecting rod 1 18 and the bottom plate 1 to move by driving the motor 2 24, so as to facilitate the cable to enter between the compression rod 1 6 and the compression rod 2 7, thereby increasing the convenience of the entire adjustment process and improving the work efficiency.

[0037] like Figure 1 and Figure 7 As shown, a mounting plate 28 is fixedly mounted on one side of the square shell 19 away from the surface of the bottom plate 1. The mounting plate 28 is designed to be longitudinally symmetrical about the center of the bottom plate 1. Threaded holes 29 are provided on the surface of the mounting plate 28. There are four threaded holes 29, and the array is distributed on the surface of the mounting plate 28. Slide grooves 31 are provided on both sides of the surface of the slide rod 26. A pulley 32 is rotatably connected to the inside of the slider 27, and the surface of the pulley 32 fits the inner wall of the slide groove 31.

[0038] The above scheme is adopted: through the design of the second mounting plate 28 and the threaded hole 29, the second mounting plate 28 can be placed on the wall inside the tunnel, and then the fixing bolt can be inserted into the threaded hole 29, so that the entire device can be fixed at a preset position, and the number of the threaded holes 29 is four, which can increase the fixing effect of the device and improve the working stability of the device. Through the design of the second slide groove 31 and the pulley 32, when the slider 27 moves, the pulley 32 will be driven to move. Since the surface of the pulley 32 fits the inner wall of the second slide groove 31, the friction between the pulley 32 and the second slide groove 31 causes the pulley 32 to rotate when it moves, so that the slider 27 can move more smoothly.

[0039] like Figure 4 As shown, square grooves 34 are provided on both sides of the interior of the fixed shell 4, and connecting blocks 35 are slidably connected inside the square grooves 34. The opposite sides of the connecting blocks 35 are fixedly connected to the surface of the slide rod 5. A square hole is provided on one side of the surface of the mounting shell 21, and the connecting plate 33 can slide inside the square hole.

[0040] The above scheme is adopted: through the design of the square groove 34 and the connecting block 35, when the slide bar 5 moves, the slide bar 5 will drive the connecting block 35 to move inside the square groove 34. Since the size of the connecting block 35 is adapted to the square groove 34, the slide bar 5 can be limited. Through the design of the mounting shell 21, since a square hole is provided on one side of the mounting shell 21, and the connecting plate 33 can be inside the square hole, the mounting shell 21 will not interfere with the movement of the connecting plate 33. When the surface of the connecting plate 33 contacts one side of the square hole, the square hole will block the movement of the connecting plate 33, thereby preventing the connecting rod 18 from moving out of the square shell 19.

[0041] like Figure 2 and Figure 4 As shown, compression rod 1 6 and compression rod 2 7 can rotate on one side of sliding rod 1 5, and compression rod 1 6 and compression rod 2 7 are both rough in design, sliding block 13 is cylindrical in design, sliding block 13 is smooth in design, and the surface of sliding block 13 fits with the inner wall of sliding groove 1 9.

[0042] The above scheme is adopted: through the design of compression rod 1 6 and compression rod 2 7, when compression rod 1 6 and compression rod 2 7 squeeze the cable, compression rod 1 6 and compression rod 2 7 will rotate due to the friction between the cable, and then when adjusting the bending state of the cable, compression rod 1 6 and compression rod 2 7 can protect the cable, and through the design of the sliding block 13, since the sliding block 13 is cylindrical and the surface is smooth, it is convenient for the sliding block 13 to move inside the slide groove 1 9, and the surface of the sliding block 13 fits with the inner wall of the slide groove 1 9, so it is convenient for the push rod 12 and the sliding block 13 to push the mounting plate 1 8 to move.

[0043] like Figure 4 and Figure 6 As shown, a blocking plate 30 is provided at the top of the transmission gear 22, and the bottom end of the blocking plate 30 is in contact with the top end of the toothed belt 23. The size of the blocking plate 30 is larger than the transmission gear 22. The support block 3 is T-shaped, and the support block 3 is longitudinally symmetrically designed about the center of the bottom plate 1. The surface of the support block 3 is in contact with the inner wall of the fixing groove 2.

[0044] The above scheme is adopted: through the design of the blocking plate 30, when the transmission gear 22 rotates, the blocking plate 30 will be driven to rotate. Since the size of the blocking plate 30 is larger than the transmission gear 22, and the bottom end of the blocking plate 30 contacts the top end of the toothed belt 23, the blocking plate 30 can limit the position of the toothed belt 23 to prevent the toothed belt 23 from detaching from the surface of the transmission gear 22 when the toothed belt 23 rotates. Through the design of the support block 3, since the support block 3 is T-shaped and the surface of the support block 3 fits the inner wall of the fixed groove 2, when the support block 3 moves, the two fixed shells 4 can be supported and limited, thereby ensuring the normal movement of the fixed shell 4.

[0045] The working principle and use process of the present invention:

[0046] First, the operator can install the device at the preset position, and then make the mounting plate 28 contact the wall inside the tunnel, and then insert the fixing bolt into the threaded hole 29, and then fix the device at the preset position. After the installation is completed, the motor 17 can be driven to rotate the two gears 11, and the gear 11 will drive the push rod 12 to rotate, and the push rod 12 will drive the sliding block 13 to move inside the slide groove 9, and then the push rod 12 and the sliding block 13 will push the mounting plate 8, the fixed shell 4 and the sliding rod 5 to move, and then the sliding rod 5 will drive the compression rod 16 and the compression rod 27 to move, and then the compression rod 16 and the compression rod 27 can be moved to the specified position;

[0047] After the adjustment is completed, the motor 24 can be driven to rotate the transmission gear 22, and the transmission gear 22 will drive the toothed belt 23 and another transmission gear 22 to rotate, and the toothed belt 23 will drive the connecting plate 33 to move, and the connecting plate 33 will drive the slider 27 to move on the surface of the slide rod 26. When the slider 27 moves, the pulley 32 will rotate inside the slide groove 21, so that the slider 27 can move more smoothly, and then the slider 27 will drive the connecting rod 20 to move, and the connecting rod 20 will drive the connecting rod 18 to move, and the connecting rod 18 will pull the bottom plate 1, the compression rod 16 and the compression rod 27 to move, and then the cable enters Between the compression rod 1 6 and the compression rod 2 7, the driving assembly 14 can then be driven to rotate the screw rod 15, and then the threaded block 16 will move on the surface of the screw rod 15, the threaded block 16 will drive the sliding rod 1 5 and the compression rod 1 6 to move upward, and the other threaded block 16 will drive the other sliding rod 1 5 and the compression rod 2 7 to descend, and then the surfaces of the compression rod 1 6 and the compression rod 2 7 will contact the surface of the cable, and then the shape of the cable is adjusted by extrusion to make it close to the expected serpentine bending state. After the adjustment is completed, the corresponding clamp can be used to fix the shape of the cable to prevent it from moving or deforming during use, and finally complete the operation process.
