Description
Technical Field
[0001] This invention relates to the field of power construction equipment technology, specifically a cable fixing bracket for substations. Background Technology
[0002] During the construction of ultra-high voltage substation projects, it is often necessary to fix the power cables and make cable heads on the construction site.
[0003] Many construction tools and equipment within substations require construction power. Cables, as the connection between the power supply and the equipment, should be laid underground or overhead, and must not be laid openly on the ground. Currently, the conventional cable trays used on construction sites are prone to detaching from the cable trays and falling to the ground under external force because there is no fixed connection between the cable and the cable tray, resulting in unsafe operations.
[0004] Cable heads refer to cable terminations and intermediate joints. When making cable heads, they need to be fixed to people or temporary supports. However, since people and temporary supports are often unstable, it will affect the accuracy of on-site workers' operations and reduce the quality of cable head making. In addition, cable heads weigh hundreds of kilograms, which not only makes operation difficult, but also, if the support is unstable, a side-tipping accident may occur, which can easily cause harm to construction workers.

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.
[0023] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.
[0024] like Figure 1 and Figure 4 As shown, a cable fixing bracket for a substation includes a main frame, a fixed component 2, and a movable component.
[0025] like Figure 1 , Figure 4 and Figure 18As shown, the main frame includes a base frame 11, on which two vertical beams 12 extend upward perpendicularly to the base frame 11, and a reinforcing beam is provided between the vertical beams 12 and the base frame 11.
[0026] In one specific embodiment, the base frame 11 in this embodiment includes a square frame formed by four side beams connected end to end. Several first connecting beams extending laterally and second connecting beams extending longitudinally are arranged within the square frame. Two vertical beams 12 are respectively located on the left and right sides of a vertically symmetrical plane extending in the front-back direction of the base frame 11. A first reinforcing beam 13 is provided between the outer side of the vertical beam 12 (with the side opposite to the two vertical beams 12 as the inner side) and the base frame 11. Second reinforcing beams 14 are respectively provided between the front and rear sides of the vertical beam 12 and the base frame 11.
[0027] like Figure 1 and Figure 4 As shown, the fixing component 2 is located between the two vertical beams 12.
[0028] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the fixing assembly 2 includes two vertical rods 21, and the two vertical rods 21 are respectively fixedly connected to the two vertical beams 12. Preferably, the two vertical rods 21 are respectively fixedly connected to the two vertical beams 12 in a detachable manner.
[0029] As one specific implementation method, such as Figure 2 , Figure 5 and Figure 7 As shown, in this embodiment, the vertical rod 21 is provided with a mounting groove 211 that extends vertically through the vertical rod 21. The mounting groove 211 is used to accommodate the vertical beam 12, and the opening of the mounting groove 211 faces outward (with the side of the two vertical rods 21 facing each other as the inner side). A positioning post 285 is provided between the vertical rod 21 and the vertical beam 12, and the positioning post 285 restricts the degree of freedom of the vertical rod 21 to slide up and down along the vertical beam 12.
[0030] A first horizontal bar 22 and a second horizontal bar 23 are arranged sequentially from bottom to top between the two vertical bars 21.
[0031] The two ends of the first horizontal bar 22 are respectively fixedly connected to the vertical bar 21.
[0032] In one specific implementation, the two ends of the first horizontal bar 22 are fixedly connected to the inner side of the vertical bar 21 (with the opposite side of the two vertical beams 12 as the inner side) by welding. Preferably, the lower end face of the vertical bar 21 is flush with the lower side face of the first horizontal bar 22.
[0033] One end of the second horizontal bar 23 is rotatably connected to the vertical bar 21 on one side via a first hinge shaft 24, and the axis of the first hinge shaft 24 is along the vertical direction; the other end of the second horizontal bar 23 is connected to the vertical bar 21 on the other side via a locking mechanism.
[0034] In one specific embodiment, two first ear plates 212 are provided on the inner side of one side of the vertical rod 21 (with the side opposite to the two vertical rods 21 as the inner side). One end of the second horizontal rod 23 is inserted between the two first ear plates 212 and is rotatably connected to the first ear plates 212 through the first hinge shaft 24.
[0035] The locking mechanism includes a limiting frame and a second ear plate 213 disposed on the inner side of the other vertical beam 12. The limiting frame includes a first guide rod 251 slidably disposed on the second crossbar 23. The first guide rod 251 is capable of sliding up and down relative to the second crossbar 23, and its lower end extends below the second crossbar 23. A cross plate 252 is disposed on the first guide rod 251 above the second crossbar 23. A limiting post 253 extending downward perpendicularly to the cross plate 252 is disposed on the cross plate 252. A first limiting hole 231 coaxially aligned with the limiting post 253 is disposed on the second crossbar 23. A second limiting hole 2131 is disposed on the second ear plate 213. When the first limiting hole 231 is aligned with the second limiting hole 2131, and the limiting post 253 is inserted into the first limiting hole 231 and the second limiting hole 2131, the second crossbar 23 is in a locked state; when the limiting post 253 is pulled out from the first limiting hole 231 and the second limiting hole 2131, the second crossbar 23 is no longer restricted by the limiting post 253 and can rotate around the first hinge axis 24.
[0036] Preferably, two second ear plates 213 are provided on the inner side of the other vertical beam 12, and when the second crossbar 23 is in the locked state, the end of the second crossbar 23 is located between the two second ear plates 213.
[0037] To ensure that the limiting frame only has the freedom to move up and down relative to the second crossbar 23, but cannot rotate relative to the second crossbar 23, two methods can be adopted: First, at least two first guide rods 251 are provided; second, the cross-section of the first guide rod 251 is a non-circular structure, such as a regular polygon, an ellipse, or other irregular closed-loop shape.
[0038] As one specific implementation method, this embodiment adopts the first approach. For example, the limiting frame includes two first guide rods 251.
[0039] A first clamping block 261, a second clamping block 262, and a driving member 263 are provided between the first crossbar 22 and the second crossbar 23.
[0040] The first clamping block 261 is disposed on the first crossbar 22. The fixed side of the driving member 263 is connected to the second crossbar 23, and the moving side of the driving member 263 is connected to the second clamping block 262. The second clamping block 262 can move up and down relative to the first clamping block 261 under the drive of the driving member 263, thereby realizing the clamping and releasing of the cable 4.
[0041] The drive component 263 can be a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. In this embodiment, the drive component 263 is an electric actuator.
[0042] A push plate 2621 is fixedly disposed on the second clamping block 262 below the first guide rod 251. When the second clamping block 262 and the push plate 2621 move upward under the drive of the driving member 263, the push plate 2621 can push the entire limiting frame upward. Figure 16 and Figure 17 As shown, when the second clamping block 262 is in the upper limit position, the limiting post 253 disengages from the first limiting hole 231 and the second limiting hole 2131, and the second crossbar 23 can rotate freely around the first hinge axis 24. When the second clamping block 262 and the push plate 2621 move downward under the drive of the driving member 263, the limiting frame can move downward under its own gravity, thereby re-inserting into the aligned first limiting hole 231 and second limiting hole 2131, thus locking the second crossbar 23.
[0043] Furthermore, a detachable baffle 2511 is fixedly provided at the lower end of the first guide rod 251, and a first spring 2512 is sleeved on the first guide rod 251 between the baffle 2511 and the second crossbar 23. For example, the baffle 2511 is fixedly connected to the lower end face of the first guide rod 251 by screws.
[0044] By setting the first spring 2512 and the baffle 2511, a driving force can be provided for the downward movement of the limit frame, which can ensure the reliability of the slide's downward movement compared to the method of moving downward by its own gravity.
[0045] Furthermore, the driving component 263 is rotatably connected to the second crossbar 23, and the first clamping block 261 is rotatably connected to the first crossbar 22. When the first clamping block 261 and the second clamping block 262 are in the clamping state, the first clamping block 261 and the second clamping block 262 can rotate as a whole.
[0046] like Figure 10 and Figure 12 As shown, a first rotating shaft 2611 is provided on the lower side of the first clamping block 261. The first rotating shaft 2611 is inserted into the first mounting hole of the first crossbar 22 and is rotatably connected to the first crossbar 22 through a first bearing assembly.
[0047] In one specific embodiment, the first bearing assembly described in this embodiment uses a first thrust ball bearing 264. A first seat hole is provided on the upper side of the first crossbar 22, and the race of the first thrust ball bearing 264 is located within the first seat hole and is fixedly connected to the first crossbar 22 by an interference fit. The first rotating shaft 2611 includes a first shaft segment and a second shaft segment whose diameter decreases sequentially from top to bottom. The race of the first thrust ball bearing 264 is sleeved on the first shaft segment and fixedly connected to the first rotating shaft 2611 by an interference fit. The race of the first thrust ball bearing 264 abuts against the lower side of the first clamping block 261.
[0048] Furthermore, a top plate 265 is provided on the lower side of the first crossbar 22, and the top plate 265 is detachably fixedly connected to the lower end face of the first rotating shaft 2611. For example, the top plate 265 is fixedly connected to the lower end face of the first rotating shaft 2611 by screws. A plurality of universal balls 2651 are evenly distributed around the first rotating shaft 2611 in a circumferential direction between the first crossbar 22 and the top plate 265. For example, eight universal balls 2651 are evenly distributed around the first rotating shaft 2611 in a circumferential direction between the first crossbar 22 and the top plate 265.
[0049] like Figure 10 , Figure 11 and Figure 14 As shown, the second crossbar 23 has a second mounting hole extending vertically through it. A second rotating shaft 266 is disposed within the second mounting hole, and the second rotating shaft 266 is rotatably connected to the second crossbar 23 via a second bearing assembly. The fixed side of the drive component 263 is fixedly connected to the lower end of the second rotating shaft 266 via a connecting bracket 267.
[0050] In one specific embodiment, the second rotating shaft 266 in this example includes a third shaft segment, a fourth shaft segment, a fifth shaft segment, and a sixth shaft segment whose diameter decreases sequentially from top to bottom. The second bearing assembly includes a second thrust ball bearing 2681 and a roller bearing 2682. The roller bearing 2682 can be a deep groove ball bearing, a cylindrical roller bearing 2682, or a tapered roller bearing 2682, etc. A second seat hole is provided on the upper side of the second crossbar 23, and the seat ring of the second thrust ball bearing 2681 is located in the second seat hole and is fixedly connected to the second crossbar 23 by an interference fit. The shaft ring of the second thrust ball bearing 2681 is sleeved on the fourth shaft segment and fixedly connected to the second rotating shaft 266 by an interference fit, with the shaft ring of the second thrust ball bearing 2681 abutting against the stepped surface between the third and fourth shaft segments. The roller bearing 2682 is sleeved on the sixth shaft segment. The upper end face of the inner ring of the roller bearing 2682 abuts against the stepped surface between the fifth and sixth shaft segments, and the upper end face of the outer ring of the roller bearing 2682 abuts against the stepped surface of the second mounting hole. A retaining ring for the hole is provided on the side wall of the second mounting hole, located below the outer ring of the roller bearing 2682. The connecting frame 267 includes a connecting plate 2671, and the fixed side of the driving member 263 is fixedly connected to the connecting plate 2671 by screws. A top cylinder 2672 is provided on the upper side of the connecting plate 2671, and the lower end of the second rotating shaft 266 is inserted into the top cylinder 2672 and fixedly connected to the connecting plate 2671 by screws. The upper end of the top cylinder 2672 abuts against the lower end face of the inner ring of the roller bearing 2682.
[0051] Furthermore, a second guide rod 269 is provided between the second clamping block 262 and the connecting frame 267. The lower end of the second guide rod 269 is fixedly connected to the second clamping block 262 in a detachable manner, and the upper end of the second guide rod 269 is slidably connected to the connecting frame 267.
[0052] As one specific implementation method, such as Figure 7 , Figure 13 and Figure 14As shown, in this embodiment, connecting ear plates 2622 are respectively provided on both sides of the second clamping block 262, and the lower end of the second guide rod 269 is connected and fixed to the connecting ear plates 2622 by a flange connection. Vertical plates 2673 extending downwards perpendicular to the connecting plate 2671 are respectively provided on both sides of the connecting plate 2671. A guide ear plate 2674 extending outwards perpendicular to the vertical plate 2673 (with the opposite side of the two vertical plates 2673 as the inner side) is provided at the lower end of the vertical plate 2673. A guide member cooperating with the second guide rod 269 is provided on the guide ear plate 2674. For example, the guide member is a linear bearing 2675.
[0053] Preferably, the axis of the clamping groove of the second clamping block 262 for receiving the cable 4 is located in the vertical plane defined by the axes of the two second guide rods 269.
[0054] Preferably, when the first clamping block 261 and the second clamping block 262 are in a clamping state, the upper side of the second guide rod 269 is located below the second crossbar 23.
[0055] Furthermore, such as Figure 11 and Figure 12 As shown, a first tension spring 271 is provided between the first clamping block 261 and the first crossbar 22. When the axis of the clamping groove of the first clamping block 261 is perpendicular to the first crossbar 22, the axis of the first tension spring 271 intersects the rotation axis of the first clamping block 261, and the axis of the first tension spring 271 is perpendicular to the axis of the clamping groove of the first clamping block 261. A second tension spring 272 is provided between the connecting frame 267 and the second crossbar 23. When the axis of the clamping groove of the second clamping block 262 is perpendicular to the second crossbar 23, the axis of the second tension spring 272 intersects the rotation axis of the second clamping block 262, and the axis of the second tension spring 272 is perpendicular to the axis of the clamping groove of the second clamping block 262.
[0056] By setting the first tension spring 271, the first clamping block 261 can be positioned perpendicular to the first crossbar 22 in a free state. By setting the second tension spring 272, the second clamping block 262 can be positioned perpendicular to the second crossbar 23 in a free state. In this way, when installing the cable 4, simply rotating the second crossbar 23 to a position parallel to the first crossbar 22 can ensure that the first clamping block 261 and the second clamping block 262 are aligned, eliminating the need for manual adjustment and simplifying the operation.
[0057] Furthermore, such as Figure 16As shown, two guide rods 2623 are respectively provided on the lower side of the second clamping block 262 on both sides of the clamping groove of the second clamping block 262. Guide holes 2612 corresponding to the guide rods 2623 are respectively provided on both sides of the clamping groove of the first clamping block 261. Thus, when the first clamping block 261 and the second clamping block 262 clamp the cable 4, the first clamping block 261 and the second clamping block 262 can be connected into a rigid whole through the guide rods 2623. This prevents the first clamping block 261 and the second clamping block 262 from rotating relative to each other under the force of the cable 4, and also prevents the cable 4 from disengaging from the clamping space between the first clamping block 261 and the second clamping block 262, ensuring the reliability of the clamping.
[0058] Furthermore, such as Figure 1 , Figure 4 and Figure 18 As shown, the vertical beam 12 has multiple positioning holes 121 evenly distributed along the vertical direction to accommodate the positioning posts 285. This allows for convenient height adjustment of the entire fixing assembly 2, thereby meeting the environmental requirements of different construction sites.
[0059] Furthermore, in order to facilitate the adjustment of the height of the fixed component 2, such as... Figure 5 and Figure 15 As shown, each of the vertical rods 21 is provided with a gripping mechanism, and the two gripping mechanisms are located on the same side of the fixing assembly 2.
[0060] The gripping mechanism includes a gripping rod 281, which comprises a gripping portion and connecting portions located at its upper and lower ends. One end of the connecting portion is fixedly connected to the gripping portion, and the other end is fixedly connected to the vertical rod 21. In one specific embodiment, the connecting portion and the gripping portion are an integral structure, and the other end of the connecting portion is fixedly connected to the vertical rod 21 by welding. Two third guide rods 282 are provided between the gripping portion of the gripping rod 281 and the vertical rod 21. One end of the third guide rod 282 is fixedly connected to the gripping portion of the gripping rod 281, and the other end is fixedly connected to the vertical rod 21. A sliding rod 283 is provided between the gripping portion of the gripping rod 281 and the vertical rod 21. The sliding rod 283 has a guide hole that mates with the third guide rod 282, and a second spring 284 is sleeved on the third guide rod 282 between the gripping portion and the sliding rod 283. The positioning post 285 is located on the side of the sliding rod 283 facing the vertical rod 21, and one end of the positioning post 285 facing the sliding rod 283 is fixedly connected to the sliding rod 283 by welding. Preferably, the sliding rod 283 is provided with a plurality of positioning posts 285. As a specific embodiment, in this embodiment, the sliding rod 283 is provided with two positioning posts 285.
[0061] Furthermore, the sliding rod 283 has a recessed portion 2831 located between the two third guide rods 282, recessed towards the gripping side. Thus, even when the sliding rod 283 is pressed against the vertical rod 21 under the action of the second spring 284, there is still a certain distance between the recessed portion 2831 and the vertical rod 21, allowing the operator to easily insert their fingers to pull the sliding rod 283.
[0062] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 18 As shown, the movable assembly includes two movable parts with identical structures and symmetrical arrangement.
[0063] The movable component includes a longitudinal beam 311 extending longitudinally, located between two vertical beams 12. A fourth guide rod 312 is provided at each end of the longitudinal beam 311. The fourth guide rod 312 is slidably connected to a guide seat 313 mounted on the base frame 11, and the sliding direction of the fourth guide rod 312 is perpendicular to the longitudinal beam 311, i.e., along the left-right direction. One end of the fourth guide rod 312 is fixedly connected to the longitudinal beam 311, and the other end of the fourth guide rod 312 is connected to a support rod 315 via a pull rod 314. The middle part of the support rod 315 is hinged to the third ear plate 111 set on the base frame 11 through the second hinge shaft 316. The lower end of the support rod 315 is provided with a traveling wheel 3151. One end of the pull rod 314 is hinged to the upper end of the support rod 315 through the third hinge shaft 317. The other end of the pull rod 314 is hinged to one end of the opposite longitudinal beam 311 of the fourth guide rod 312 through the fourth hinge shaft 318.
[0064] In one specific implementation, one end of the fourth guide rod 312 in this embodiment is fixedly connected to the longitudinal connector via a flange connection.
[0065] A lead screw 32 is provided between the two moving parts. The lead screw 32 passes through the two vertical beams 12 in a transverse direction, and both ends of the lead screw 32 are rotatably connected to the vertical beams 12 via third bearing assemblies 33. Nuts 319 that cooperate with the lead screw 32 are respectively provided on the two longitudinal beams 311. When the lead screw 32 is rotated, the two longitudinal beams 311 can move towards each other or away from each other under the drive of the nut 319.
[0066] A handwheel 34 is provided at one end of the lead screw 32. In one specific embodiment, the handwheel 34 is located at the left end of the lead screw 32.
[0067] The work process is as follows: First, move the cable fixing bracket to the working position as a whole, and then turn the handwheel 34. This drives the two longitudinal beams 311 to move towards each other via the lead screw 32 and lead nut 319. At this time, the upper end of the support rod 315 swings inward under the drive of the fourth guide rod 312 and pull rod 314, and the traveling wheel 3151 at the lower end of the support rod 315 swings outward and tilts upward. Simultaneously, the base frame 11 moves downward until it contacts the ground, i.e., as shown in the image. Figure 18 The state shown.
[0068] Second, spread your hands apart so that your palms are on the outside of the grip. Insert the four fingers (excluding the thumb) into the gap between the recess 2831 of the sliding rod 283 and the vertical rod 21. Then, pull the sliding rod 283 towards the grip with your four fingers until the positioning post 285 is completely disengaged from the vertical beam 12. Figure 15 The state shown is as follows. At this time, the fixing part 2 can move up and down along the vertical beam 12. Then, after moving the fixing part 2 up and down to a suitable position and aligning the fixed position with the corresponding positioning hole 121, the four fingers are released, and the sliding rod 283 moves to one side of the vertical beam 12 under the action of the second spring 284 until the positioning post 285 is inserted into the corresponding positioning hole 121, and the fixing part 2 is re-fixed to the vertical beam 12.
[0069] Third, activate the drive unit 263, causing the second clamping block 262 to move upward under the drive of the drive unit 263, and under the pushing action of the push plate 2621, until the limiting post 253 of the limiting frame is completely pulled out from the first limiting hole 231 and the second limiting hole 2131, that is, as Figure 16 The state shown.
[0070] Fourth, rotate the second crossbar 23 to open the fixing part 2, i.e. Figure 17 The state shown.
[0071] Fifth, place the cable 4 inside the fixing part 2 (i.e., inside the U-shaped structure with the opening facing upward formed by the first horizontal bar 22 and the vertical bar 21), and then rotate the second horizontal bar 23 to align the first limiting hole 231 with the second limiting hole 2131.
[0072] Sixth, place the cable 4 in the clamping groove of the first clamping block 261, and then activate the drive component 263 to move the second clamping block 262 downward under the drive of the drive component 263 until the cable 4 is clamped between the first clamping block 261 and the second clamping block 262. During this process, the limiting post 253 of the limiting frame will also be re-inserted into the aligned first limiting hole 231 and second limiting hole 2131 under the elastic action of the first spring 2512, thereby locking and fixing the second crossbar 23.
[0073] If it is necessary to move the cable fixing bracket after construction is completed or during construction, the following operations shall be performed: First, turn the handwheel 34 to make the two longitudinal beams 311 move in opposite directions. At this time, the upper end of the support rod 315 will swing outward under the pushing action of the pull rod 314 and the fourth guide rod 312, and the traveling wheel 3151 at the lower end of the support rod 315 will swing inward, thereby supporting the entire device and detaching the base frame 11 from the ground. Then, the entire device can be moved.
