Description

Technical Field

[0001] This utility model relates to the field of cable well and substation technology, specifically a cable well routing guide device. Background Technology

[0002] Substations are crucial for the construction of rural power grids, serving as the "starting point" of electrical energy. Cable wells, on the other hand, are the "joints" of the power transmission channels; without them, the substation's outgoing lines are essentially choked. Cable wells not only perform critical functions such as cable turning, branching, jointing, fireproofing, and providing access for maintenance, but they are also essential passageways for maintenance personnel for daily inspections, fault location, and emergency repairs. Their location, size, drainage, and fire resistance directly determine whether cables can safely and quickly cross roads, rivers, and building complexes, ultimately achieving a reliable connection between the substation and the load center. In short, cable wells are the "external lifeline" of the substation's cable system.

[0003] In new construction or expansion projects, cable routing within cable wells is frequent. A single cable often needs to be threaded back and forth between multiple cable wells, each with anywhere from two to six openings. The two openings within the same well must coordinate synchronously, making the operation difficult and labor-intensive. Currently, various tools are available for cable routing within wells, such as protective mesh sleeves, manual hoists, and small traction machines, but none can achieve the desired effect in cable routing and protection. The main reasons are: First, the limited space underground restricts the adjustable range of embedded equipment due to size limitations, making them inflexible in use. For example, various cable-laying frames with rollers can only barely manage the guiding position and angle, making them inconvenient to use. External traction equipment cannot be used deep underground; for example, traction machines used underground are prone to causing cable wear and tear on the cable and the entry / exit points due to excessive pulling height. Second, most existing tools require coordinated operation. For example, with traction equipment, pulling and positioning require different people working together, resulting in low efficiency and high error rates. Therefore, in the current operation, the wiring and guidance of the four cable inlets and outlets has become a bottleneck restricting the rapid power supply of the substation. It not only takes a long time and has a heavy workload, but also results in cable loss. Utility Model Content

[0004] The purpose of this utility model is to provide a cable well routing guide device, which is suitable for cable laying operations in underground cable wells, significantly reducing the workload, improving the accuracy and safety of cable laying, and solving the problem of cable swaying and wear.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A cable well routing guide device includes a mounting frame, the mounting frame including a base, with strip plates telescopically fitted at both ends of the base in opposite directions, a right-angle clamping plate at the outer end of the strip plate, one side of the right-angle clamping plate being fixed at a 45-degree angle to the strip plate, a sleeve hinged to the center of the bottom surface of the base, a telescopic tube telescopically fitted at the end of the sleeve, and a wheel frame with adjustable height above the sleeve, on which guide wheels are mounted.

[0007] The seat has a vertically extending partition in the center, and sliding openings at both ends of the partition. A strip plate passes through the sliding openings and the two slide together. A baffle parallel to the partition is provided on the side of the sliding opening away from the partition. The thickness of the strip plate is adapted to the distance between the partition and the baffle. A first threaded sleeve passes through the baffle, and a first bolt is internally threaded onto the first threaded sleeve. The inner end of the first bolt contacts the strip plate.

[0008] The telescopic tube is provided with a support plate that is fixed vertically to the end away from the sleeve. When the telescopic tube is horizontal, the support plate extends vertically.

[0009] The support plate is a sheet material with a right-angle bend, or the support plate is an arc-shaped plate.

[0010] A sliding sleeve is movably fitted onto the sleeve. The sliding sleeve is fitted onto the outside of the sleeve and slides along its length. A second threaded sleeve is provided on the sliding sleeve, penetrating its side wall. A second bolt is threaded into the second threaded sleeve. Multiple through holes are penetrating the sleeve and are equidistantly distributed in a row along the length of the sleeve. The second bolt is movably inserted into the through hole, and the bottom end of the second bolt contacts the telescopic tube.

[0011] A lifting sleeve is fixed to one side of the sliding sleeve and is perpendicular to the sliding sleeve. A lifting tube is slidably fitted inside the sliding sleeve. A positioning hole is provided on the side wall of the lifting tube. A third threaded sleeve passes through the lifting sleeve. A butterfly-shaped third bolt is threaded inside the third threaded sleeve. The third bolt is movably pinned to the positioning hole. A swing seat is provided eccentrically on the top of the lifting tube near the sliding sleeve. A connecting shaft is provided on the swing seat. The axis of the connecting shaft is coplanar with the center of the sleeve. The wheel frame is rotatably connected to the connecting shaft.

[0012] The guide wheels are two in number and are symmetrically mounted on the wheel frame relative to the connecting axis.

[0013] The guide wheel has a groove in the center, and a circular tray is provided at the bottom of the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This guiding device can be installed at the entrance and exit of a cable well through telescopic adjustment. Utilizing a reverse telescopic strip plate and an L-shaped right-angle clamping plate, it can be quickly secured at the diagonal position of the well opening, achieving gravity bearing and height positioning. The hinged sleeve at the bottom of the base and the telescopic tube form a "support rod" structure. The support plate, tightened against the well corner, forms a three-point support with the clamping plate, ensuring the device remains stable and does not wobble at the entrance and exit height. This allows for fixed installation at the corresponding entrance and exit height, solving the problems of insufficient height, easy displacement, inaccurate alignment, and laborious manual diagonal pulling, as well as cable swaying and wear associated with traditional cable trays at the bottom of wells. Furthermore, it is easy to assemble and disassemble, significantly reducing labor intensity and improving cable laying accuracy and safety. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Example 1:

[0024] This example demonstrates the design of a common cable well structure—a four-way rectangular cable well. The cable well is rectangular, with entrances and exits located in the center of each of its four walls, designated as the east, south, west, and north entrances. These correspond to four cable penetration holes around the well, allowing for simultaneous introduction and exit of cables from multiple directions.

[0025] In existing operations, it is common practice to directly erect the cable guide frame at the bottom of the well. However, the height of the cable guide frame is often insufficient, and it is difficult to fix it securely. This often leads to displacement and cable detachment during cable delivery, and the position of the cable is also difficult to align with the expected position. Another method is to use equipment or a manual hoist to pull the cable diagonally, which is a heavy workload and can only be done at an angle, resulting in significant cable sway and easy abrasion.

[0026] This guiding device can be directly installed at the corresponding entrance / exit height inside the well to stably guide the cable. Its main structure includes a mounting frame, which includes a base 1. A vertically extending partition 2 is located at the center of the base 1. Sliding openings 3 are located at both ends of the partition 2. A baffle 4, parallel to the partition 2, is located on the side of the sliding opening 3 away from the partition 2. A strip plate 7, slidably connected to the sliding opening 3, is located between the partition 2 and the baffle 4. The thickness of the strip plate 7 is adapted to the spacing between the partition 2 and the baffle 4. The strip plate 7 is further constrained by the baffle 4 and the partition 2, stabilizing the extension and retraction of the partition 2.

[0027] In the above structure, the base 1 has two strip plates 7 that slide and engage with it. In actual use, the sliding and extending directions of the strip plates 7 are opposite, thus achieving bidirectional outward extension and retraction. This structure is simple and, compared to complex slide rails and sliding structures, can be assembled using a simple design. Furthermore, the two strip plates 7 can be slid outwards and pulled out, facilitating replacement of the strip plates 7 and allowing selection of strip plates 7 within the required length range.

[0028] A first threaded sleeve 5 passes through the baffle 4, and a first bolt 6 is internally threaded onto the first threaded sleeve 5. The first bolt 6 is a wing bolt. By tightening it, the inner end of the first bolt 6 abuts against the surface of the strip plate 7, thereby limiting the extension and retraction of the strip plate 7 relative to the seat 1 and locking the extension length of the two strip plates 7.

[0029] The outer end of the strip plate 7 is provided with an L-shaped right-angle clamping plate 8. The right-angle clamping plate 8 can be made of angle steel cut and welded to the outer end of the strip plate 7. One side of the right-angle clamping plate 8 is welded and fixed to the strip plate 7 at a 45-degree angle. The inside corners of the two right-angle clamping plates 8 are set in the same direction. By clamping the right-angle clamping plates 8 at the adjacent entrances and exits of the cable well, the guiding position can be positioned on the diagonal, so that the bending and pulling position of the cable is located at the optimal position on the diagonal.

[0030] If the entrance / exit is square, the right-angle clamping plate 8 is placed on the bottom side of the square opening. The weight and support of the right-angle clamping plate 8 and the device by the bottom side of the square opening enhance the stability of the device at that height, facilitating quick positioning and height constraint. If the entrance / exit is circular, the right-angle clamping plate 8 is clamped in the center of the circular opening (where the distance between adjacent entrances / exits is closest), and the extended length of the strip plate 7 is tightened and locked, thereby constraining the height of the device.

[0031] A hinge seat 9 is centrally located at the bottom of the base 1. A sleeve 10 is rotatably connected to the hinge seat 9. In use, the swing direction of the sleeve 10 is opposite to the inside corner direction of the right-angle clamp 8. It is used to act on the corner of the cable well away from the cable threading point.

[0032] The sleeve 10 is a straight-extending square tube, and its end away from the hinge seat 9 is provided with a telescopic tube 11 that is telescopically coordinated with it. Both the telescopic tube 11 and the sleeve 10 can be made by cutting and combining square tubes, and can be simply connected by snap-fit.

[0033] The telescopic tube 11 is provided with a support plate 12 that is welded and fixed perpendicularly to the end of the sleeve 10. The support plate 12 is a plate with a right-angle bend. When the telescopic tube 11 is horizontal, the support plate 12 is vertical.

[0034] The center of the inside corner of the support plate 12 is welded and fixed to the outer end of the telescopic tube 11.

[0035] By adjusting the length of the telescopic tube 11 and the sleeve 10, the support plate 12 is tightly fitted at one corner of the cable well (away from the two inlets and outlets where the cable is run). Utilizing the right-angle shape and height extension of the support plate 12, the support stability at the corner of the cable well is increased, thus achieving the effect of auxiliary fixation of the device along the diagonal line inside the well using the "support rod" principle. The support plate 12 provides secondary support, while the retractable right-angle clamping plate 8 primarily secures the device at the inlet and outlet height, providing a stable support for the subsequent guide cable. Not limited to this example, an arc-shaped support plate 12 can also be used in conjunction with a prototype cable well.

[0036] The sleeve 10 has multiple through holes 13, which are equidistantly distributed in a row along the length of the sleeve 10.

[0037] A sliding sleeve 14 is movably fitted onto the sleeve 10. The sliding sleeve 14 is made by cutting and drilling a square tube larger than the sleeve 10. The sliding sleeve 14 is fitted onto the outside of the sleeve 10 and slides along its length. The sliding sleeve 14 is provided with two second threaded sleeves 15 that penetrate its sidewalls. In this example, two second threaded sleeves 15 are respectively set at both ends of the sliding sleeve 14. This example is not limited to this one; one or other numbers of second threaded sleeves 15 can be used. A second bolt 16 is threaded into the second threaded sleeve 15. The second bolt 16 is a wing bolt. The second bolt 16 is inserted downward by rotating with the second threaded sleeve 15, penetrating through the through hole 13 and pressing against the surface of the telescopic tube 11. The second bolt 16 locks the relative position of the sliding sleeve 14 and the sleeve 10, as well as the sleeve 10 and the telescopic tube 11, in one step. This simplifies the operation steps and allows for quick adjustment and fixing.

[0038] The advantage of using two second threaded sleeves 15 respectively at both ends in this example is that either second threaded sleeve 15 can be flexibly selected. When the position of the sliding sleeve 14 spans the sleeve 10 and the telescopic tube 11, the second bolt 16 can be tightened using the second threaded sleeve 15 near the seat 1 to ensure that it can pass through the through hole 13 on the sliding sleeve 14 and abut against the telescopic tube 11. When the position of the sliding sleeve 14 is entirely on the sleeve 10, either two or any one second threaded sleeve 15 can be used to tighten the second bolt 16.

[0039] A lifting sleeve 17 is fixed to one side of the sliding sleeve 14 and is vertically fixed to the sliding sleeve 14. When the sliding sleeve 14 is in a horizontal state, the lifting sleeve 17 extends vertically. A lifting tube 18 is slidably fitted inside the sliding sleeve 14. A positioning hole 25 is provided on the side wall of the lifting tube 18. A third threaded sleeve 19 passes through the lifting sleeve 17. A butterfly-shaped third bolt 20 is threaded inside the third threaded sleeve 19. The third bolt 20 is pinned to the positioning hole 25 to limit the height of the lifting tube 18. The top of the lifting pipe 18 is eccentrically provided with a swing seat 21 near the sliding sleeve 14. The swing seat 21 is provided with a connecting shaft, and a wheel frame 22 is rotatably connected to the connecting shaft. The axis of the connecting shaft is coplanar with the center of the sleeve 10, ensuring that the wheel frame 22 is located in the center of the two inlets and outlets (diagonal position of the cable well). The wheel frame 22 is a Y-shaped wheel frame 22. Two guide wheels 23 are symmetrically rotatably installed on the wheel frame 22 relative to the connecting shaft. The center of the guide wheel 23 is provided with a wheel groove. The wheel groove is used to bypass the cable, guide and pull the cable lead, and prevent the cable from running smoothly in the inlet and outlet. The bottom of the wheel groove is provided with an outwardly protruding circular tray 24. Through the expanded diameter tray 24 structure, the cable is assisted in supporting the cable and preventing it from leaving the cable groove when it is pulled loose, ensuring that the cable is effectively guided in the cable groove.

[0040] Based on the above structure, this guiding device can guide the cable routing between the two openings of the cable well. The retractable strip plate 7 positions the cable between the two openings and helps limit the installation height, ensuring the cable position is within the height range of the entrance and exit, achieving same-level guidance and avoiding pulling the cable upwards or downwards. By tensioning the support rod, the support plate 12 can be supported at one corner of the cable well, facilitating the installation of the entire device. Operation is simple, and the device is reliably fixed after installation, overcoming the problem of difficulty in coordinating auxiliary facilities within the cable well. The guide wheel 23 allows for adjustment of the cable's guiding height and position, and is located in the center of the two entrances and exits, facilitating adjustment to correspond to the expected optimal guiding position. The guidance is stable and does not wobble, improving the quality and efficiency of cable routing operations in the cable well and reducing operational difficulty.
