Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to an auxiliary device for cable trench construction in power engineering. Background Technology

[0002] In the field of power engineering, cable trenches serve as crucial infrastructure for cable laying, and their construction quality and efficiency directly impact the stability and safety of power transmission. Cable trenches typically require the laying of a large number of cables, and the proper support and arrangement of these cables is paramount. Auxiliary construction devices installed on the trench walls to support the cables are a key component of cable trench construction.

[0003] Currently, most cable support devices used in power engineering cable trenches are made of rigid plastic or metal. These materials can meet the basic requirements of cable support to a certain extent, possessing a certain strength and load-bearing capacity. However, in practical applications, these support devices have certain shortcomings in assisting construction.

[0004] For example, during cable laying, limiting and adjusting the position of the cable is a very important operation. For instance, at the bends in the cable trench, the cable needs to be limited to maintain a bending deformation similar to that of the cable trench. However, after the cable is bent, it will have a rebound reaction force. At this stage, cable ties are usually used for limiting. When the position of the cable needs to be adjusted according to actual needs later, it is often necessary to remove some of the cable ties, which is a relatively troublesome and time-consuming operation.

[0005] Furthermore, in terms of cable fixing effectiveness, cable ties are a relatively simple and ineffective method. When cables are subjected to external forces, such as thermal expansion and contraction or external vibrations, the cable ties are prone to loosening, causing the cables to shift on the support device. This not only affects the neatness of the cable arrangement but may also cause the cables to become entangled, increasing electromagnetic interference between cables and reducing the stability and reliability of power transmission. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary device for cable trench construction in power engineering, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for cable trench construction in power engineering, comprising: a base plate, a support plate fixedly attached to the right surface of the base plate, multiple cables laid on the upper surface of the support plate, limiting units provided on both sides of the outer wall of the cables, the limiting unit comprising: multiple partitions, the multiple partitions respectively attached to both sides of the outer wall of the multiple cables, a vertical rod fixedly attached to the bottom end of the partition, the vertical rod penetrating the top of the support plate through a first horizontal groove, a bottom block fixedly attached to the bottom end of the vertical rod, multiple inserts fixedly attached to the lower surface of the bottom block, toothed plates inserted into the bottom end of the inserts, the toothed plates being fixedly connected to the inner bottom end of the support plate, a sleeve plate fitted on the outer wall of the vertical rod, a pair of sliding strips fixedly attached to the outer wall of the vertical rod, the sliding strips being slidably limited connected to the sleeve plate, ball bearings being slidably engaged at the four corners of the upper surface of the sleeve plate, the ball bearings being attached to the upper part of the support plate, and a compression spring fixedly connected between the sleeve plate and the bottom block.

[0008] Preferably, a fixing unit is provided above the cable. The fixing unit includes: multiple pressure blocks, the pressure blocks being located above the outer wall of the cable and abutting against the cable; a slider being connected above the pressure blocks; a strip being provided on the inner wall of the slider; the outer wall of the strip being in clearance fit with the inner wall of the slider; a second transverse groove being formed on the upper surface of the strip; multiple first bolts being inserted into the upper surface of the strip; the first bolts passing through the second transverse groove; and the bottom end of the outer wall of the first bolt being threadedly connected to the partition plate.

[0009] Preferably, the bottom end of the pressing block has a double-sloped structure.

[0010] Preferably, an anti-slip pad is fixed to the lower surface of the pressure block, and the anti-slip pad is in contact with the contact surface of the cable.

[0011] Preferably, the pressure block is connected to the slider via an auxiliary unit, and a pair of vertical cylinders are pressed between the pressure block and the slider. A pair of grooves are provided on the lower surface of the pressure block, and a through-hole corresponding to the grooves is provided on the lower surface of the anti-slip pad. A second bolt is provided inside the groove, and the second bolt passes through the pressure block and the vertical cylinder in sequence. The second bolt is threadedly connected to the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This auxiliary device for cable trench construction in power engineering has the following advantages over traditional technology:

[0013] Through the cooperation of the base plate, support plate, cable, and limiting unit, the operator can apply force to the cable to make its angle similar to the angle of the cable trench bend. During this process, the operator pulls the partition upward, causing the compression spring to compress and deform. At this time, the insert block separates from the toothed plate, and the toothed plate no longer limits the insertion block. Then, the partition is moved laterally so that it abuts against the outer wall of the bent cable. Then, the upward pulling force on the partition is released, the compression spring rebounds, and the insert block reconnects with the toothed plate, thus limiting the position of the partition. Once the position of the partition is determined, it can resist the rebound reaction force after the cable bends, eliminating the need for cable ties for limiting. Moreover, if the cable position needs to be adjusted laterally according to actual needs, it is only necessary to pull the partition upward again and move it laterally. The operation is relatively simple and convenient, providing convenience for cable laying operations in power engineering cable trenches.

[0014] Through the cooperation of the base plate, support plate, cable, limiting unit, and fixing unit, after the cable laid inside the cable trench is adjusted and limited by the partition, the operator places the strip above the partition and then applies a lateral force to the slider, causing it to slide laterally on the strip. At this time, the pressure block below the slider is directly above the cable. Next, the first bolt is used to pass through the second transverse groove to thread the strip to the partition. When the pressure block is fully in contact with the cable and pressed tightly, the first bolt is stopped from being rotated. Thus, the clamping and fixing of the cable is completed. This fixing method is much stronger than the cable tie fixing method. When the cable is subjected to external force, it is not easy to shift, which helps to keep the cable neatly arranged and thus ensures the stability and reliability of power transmission.

[0015] Through the cooperation between the base plate, support plate, cable, limiting unit, fixing unit and auxiliary unit, when there is a difference in the outer diameter of multiple cables laid on the support plate during construction, the operator selects vertical cylinders of different lengths and places them between the pressure block and the slider. In this way, when the fixing unit is used to fix the cable, the multiple pressure blocks on the lower surface of the plate can effectively press the multiple cables with different outer diameters. That is, the pressure block and the support plate can effectively clamp the cable, thereby improving the overall adaptability of the device. Its application range is relatively wide and it is easy to promote and use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: an auxiliary device for cable trench construction in power engineering, comprising: a base plate 1, a support plate 2 fixedly attached to the right surface of the base plate 1, multiple cables 3 laid on the upper surface of the support plate 2, and limiting units provided on both sides of the outer wall of the cables 3, the limiting units comprising: multiple partitions 4, the multiple partitions 4 respectively attached to both sides of the outer wall of the multiple cables 3, a vertical rod 5 fixedly attached to the bottom end of the partition 4, the vertical rod 5 passing through the top of the support plate 2 through a first horizontal groove 6, and the bottom end of the vertical rod 5 fixedly attached to... There is a base block 7, and multiple insert blocks 8 are fixedly connected to the lower surface of the base block 7. A toothed plate 9 is inserted into the bottom end of the insert block 8. The toothed plate 9 is fixedly connected to the inner bottom end of the support plate 2. A sleeve plate 10 is fitted on the outer wall of the vertical rod 5. A pair of slide bars 11 are fixedly connected to the outer wall of the vertical rod 5. The slide bars 11 are slidably limited to the sleeve plate 10. Roller balls 13 are slidably engaged at the four corners of the upper surface of the sleeve plate 10. The roller balls 13 are attached to the upper part of the inner side of the support plate 2. A compression spring 12 is fixedly connected between the sleeve plate 10 and the base block 7.

[0025] In the specific implementation process, it is worth noting that the base plate 1 and the support plate 2, as the basic supporting components of the entire device, are made of high-strength alloy steel. This material has high strength and good toughness, and can withstand large external forces without deformation, ensuring stability and reliability in the complex environment of the cable trench. The partition plate 4 is made of engineering plastic, which has the characteristics of high strength, light weight, and corrosion resistance. When it is attached to the outer wall of the cable 3, it will not damage the cable. The vertical rod 5 is made of stainless steel, which has high strength and corrosion resistance, ensuring that it will not rust during long-term use and affect the normal operation of the device. The bottom block 7 and the insertion block 8 are integrally molded structures made of hard plastic or metal. This structure makes the insertion of the insertion block 8 into the toothed plate 9 more secure. It is not easy to loosen when subjected to external force. The tooth design on the toothed plate 9 is reasonable, and the tooth pitch and tooth height are precisely calculated. It can achieve stable and reliable insertion and separation with the insert block 8, and meet the fixing requirements of the partition 4 in different positions. The sliding limit connection between the slide bar 11 and the sleeve plate 10 can ensure that the sleeve plate 10 moves smoothly and steadily. There will be no relative rotation between the sleeve plate 10 and the vertical rod 5. The ball 13 is composed of a groove seat and a steel ball. The steel ball can roll, but cannot be separated from the groove seat. The surface of the steel ball is smooth. When it rolls inside the upper part of the support plate 2, it can reduce the friction of the sleeve plate 10 when it moves, making the operation easier and less strenuous. The elastic coefficient of the compression spring 12 is 10-30N / CM, which can ensure sufficient insertion force between the insert block 8 and the toothed plate 9.

[0026] Furthermore, a fixing unit is provided above the cable 3. The fixing unit includes multiple pressure blocks 14. The pressure blocks 14 are located above the outer wall of the cable 3 and abut against the cable 3. A slider 15 is connected above the pressure blocks 14. A strip 16 is provided on the inner wall of the slider 15. The outer wall of the strip 16 is in clearance fit with the inner wall of the slider 15. A second transverse groove 17 is opened on the upper surface of the strip 16. Multiple first bolts 18 are inserted into the upper surface of the strip 16. The first bolts 18 pass through the second transverse groove 17. The bottom end of the outer wall of the first bolt 18 is threadedly connected to the partition 4.

[0027] In the specific implementation process, it is worth noting that the pressure block 14 and the slider 15 are made of high-strength plastic material, which has good wear resistance and can maintain its shape and performance stability during long-term use. The clearance fit between the inner wall of the slider 15 and the strip 16 is highly precise, ensuring that the slider 15 slides smoothly on the strip 16 without shaking or jamming. The strip 16 is made of stainless steel, which has high strength and corrosion resistance. The width and depth of the second transverse groove 17 opened on its upper surface are precisely designed to ensure that the first bolt 18 can pass through smoothly and achieve a reliable threaded connection. The first bolt 18 can withstand large tensile and shear forces, ensuring that the connection of the fixing unit is firm and reliable.

[0028] Furthermore, the feature is that the bottom end of the pressure block 14 has a double-sloped structure.

[0029] In the specific implementation process, it is worth noting that the double-slope structure of the pressure block 14 is ingeniously designed. This structure can better adapt to cables 3 with different outer diameters. When the pressure block 14 presses the cable 3 down, the double slope can form a tighter fit with the outer surface of the cable 3, thereby improving the pressing effect and making the cable 3 less likely to be displaced when subjected to external force.

[0030] Furthermore, the feature is that an anti-slip pad 22 is fixedly attached to the lower surface of the pressure block 14, and the anti-slip pad 22 abuts against the contact surface of the cable 3.

[0031] In the specific implementation process, it is worth noting that the anti-slip pad 22 is made of rubber material and has fine anti-slip texture on its surface. These textures can increase the friction between the anti-slip pad 22 and the cable 3. When the pressure block 14 presses the cable 3, the anti-slip pad 22 can fit tightly against the surface of the cable 3, effectively preventing the cable 3 from sliding when it is pulled or vibrated by external force, further enhancing the stability of the cable fixation. At the same time, the anti-slip pad 22 also has a certain degree of elasticity, which can play a buffering role during the pressing process and reduce damage to the cable 3.

[0032] Furthermore, the pressure block 14 is connected to the slider 15 through an auxiliary unit. A pair of vertical cylinders 21 are pressed between the pressure block 14 and the slider 15. A pair of grooves 19 are provided on the lower surface of the pressure block 14. A through-hole corresponding to the groove 19 is provided on the lower surface of the anti-slip pad 22. A second bolt 20 is provided inside the groove 19. The second bolt 20 passes through the pressure block 14 and the vertical cylinder 21 in sequence. The second bolt 20 is threadedly connected to the slider 15.

[0033] In the specific implementation process, it is worth noting that the vertical cylinder 21 is made of metal and its length is available in various specifications. The operator can select a suitable length of vertical cylinder 21 based on the difference in the outer diameter of the cable 3 laid above the pallet 2 and place it between the pressure block 14 and the slider 15 to adjust the distance between the pressure block 14 and the slider 15, thereby accommodating cables 3 with different outer diameters. The design of the groove 19 ensures that the second bolt 20 does not directly contact the cable 3, avoiding damage to the outer wall of the cable 3 due to the compression of the second bolt 20. At the same time, it can ensure that the connection between the second bolt 20 and the pressure block 14, the vertical cylinder 21 and the slider 15 is firm and reliable. The second bolt 20 is a high-strength bolt that can withstand large tensile and shear forces, ensuring the connection stability of the auxiliary unit and enabling the pressure block 14 to effectively press and fix cables 3 with different outer diameters.

[0034] Working principle:

[0035] Installation of the base plate and tray, and initial cable placement:

[0036] Operators use expansion bolts to securely install base plate 1 and support plate 2 inside the cable trench of the power project. After installation, the cable 3 is placed on the surface of support plate 2, which provides initial support for the cable and ensures the initial positioning of the cable in the cable trench.

[0037] Limiting unit for bending cable:

[0038] When the base plate 1 and the support plate 2 are installed at the bend in the cable trench, the operator applies force to the cable 3 to make the angle of the cable 3 similar to the angle of the bend in the cable trench, so as to meet the laying requirements of the cable in the bend section. During this process, the operator pulls the partition plate 4 upward. The movement of the partition plate 4 causes the compression spring 12 to compress and deform. At the same time, the insert 8 separates from the toothed plate 9, and the toothed plate 9 no longer limits the insertion 8. Then, the partition plate 4 is moved laterally so that it is tightly pressed against the outer wall of the bent cable 3. Then, the upward pulling force on the partition plate 4 is released, the compression spring 12 rebounds, and pushes the insert 8 to reconnect with the toothed plate 9, thereby limiting the position of the partition plate 4. After the position of the partition plate 4 is determined, it can resist the rebound reaction force generated by the bending of the cable 3 and effectively fix the position of the cable 3 without the need to use cable ties for limiting. Moreover, if the cable position is adjusted according to actual needs later, it is only necessary to pull the partition plate 4 upward again and move it laterally. The operation is simple and convenient, improving the construction efficiency.

[0039] The fixing unit clamps and secures the cable:

[0040] After the cable 3 laid inside the cable trench is adjusted and limited by the partition 4, the fixing process begins. The operator places the strip 16 above the partition 4 and then applies a lateral force to the slider 15, causing it to slide laterally on the strip 16. At this time, the pressure block 14 below the slider 15 moves to directly above the cable 3. Next, the first bolt 18 is used to thread the strip 16 and the partition 4 through the second transverse groove 17. As the first bolt 18 is tightened, the pressure block 14 gradually moves downward. When the pressure block 14 is fully in contact with and pressed against the cable 3, the first bolt 18 is stopped. Thus, the clamping and fixing of the cable 3 is completed. This fixing method is much stronger than that of cable tie fixing. When the cable 3 is subjected to external forces, it is not easy for it to shift, which helps to keep the cable 3 neatly arranged, thereby ensuring the stability and reliability of power transmission.

[0041] Auxiliary unit adaptability to cables of different outer diameters:

[0042] During construction, when there are differences in the outer diameter of multiple cables 3 laid above the support plate 2, the auxiliary unit comes into play. The operator selects vertical cylinders 21 of different lengths and places them between the pressure block 14 and the slider 15. The vertical cylinders 21 can adjust the distance between the pressure block 14 and the slider 15 to accommodate cables 3 with different outer diameters. In this way, when the fixing unit is used to fix the cables 3, the multiple pressure blocks 14 on the lower surface of the strip 16 can effectively press the multiple cables 3 with different outer diameters. That is, the pressure block 14 and the support plate 2 can effectively clamp the cables 3, thereby improving the overall adaptability of the device, enabling it to meet the laying requirements of cables of different specifications. It has a wide range of applications and is easy to promote and use.
