Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable delivery device. Background Technology

[0002] Cable laying is a crucial step in the construction of power transmission and transformation projects. The quality and efficiency of cable laying directly affect the progress and safety of the entire project. In order to assist in the orderly release of cables, installation frames are usually used on the construction site to support cable reels. The cable reels are rotated and set on the installation frames. With the support of the installation frames, the cables on the cable reels can be stably led out.

[0003] However, power transmission and transformation projects require construction work on uneven sites. Existing mounting frames lack effective gripping or anchoring structures, making them difficult to fix stably. Under the tension of cables, they are prone to swaying, displacement, or even tipping over, which not only affects the continuity of construction but also brings serious safety hazards. In addition, during cable laying, it is usually necessary to continuously adjust the cable outgoing direction according to the predetermined route. However, the existing mounting frames are fixed in place. When the orientation needs to be adjusted, the entire mounting frame, along with the cable reel it carries, must be moved and turned manually or mechanically. The whole process is time-consuming, labor-intensive, cumbersome, and inefficient. Utility Model Content

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1 to 5 As shown, this utility model provides a cable delivery device, including a base support 1, an adjustment base 2, and a locking element 3. The base support 1 includes a base support block 11 and multiple support legs 12 connected to the base support block 11. The multiple support legs 12 are configured to support the placement surface. The adjustment seat 2 is rotatably connected to the base support block 11 and can rotate relative to the base support block 11 about a vertical adjustment axis. The top of the adjustment seat 2 is provided with a bearing part and a guide ring 201. The bearing part is configured to carry a cable reel 100, and the guide ring 201 is configured to guide the cable leading out from the cable reel 100. One of the base support block 11 and the adjustment seat 2 is provided with a locking member 3, and the other is provided with multiple locking ports 10. The locking member 3 can be adjusted between a locked position and an unlocked position. The multiple locking ports 10 are evenly distributed about the adjustment axis. When the locking member 3 is in the locked position, the locking head of the locking member 3 extends into a locking port 10 to lock the adjustment seat 2 to the base support block 11. When the locking member 3 is in the unlocked position, the locking head exits the locking port 10.

[0040] In this invention, by setting a base support 1, the cable guide device can be stably placed on the placement surface by the multiple support legs 12 of the base support 1. The multiple support legs 12 cooperate with each other to adapt to various placement surfaces under different working conditions. An adjustment seat 2 is rotatably set on the base support 1, and the adjustment seat 2 supports the cable reel 100, so that the cable reel 100 is stably supported during laying and the direction can be easily adjusted. The bearing part on the adjustment seat 2 can support the cable reel 100, and the guide ring 201 on the adjustment seat 2 can pass through to guide the cable leading out from the cable reel 100, avoiding the problem of cable twisting or tangling during laying, so that the cable... The cable can be released smoothly and orderly, effectively protecting the cable from damage and ensuring the technical effect of construction quality. On this basis, a locking element 3 is set between the bottom support block 11 of the bottom support seat 1 and the adjusting seat 2. When the locking element 3 is in the locked position, the locking head of the locking element 3 extends into a locking port 10, locking the adjusting seat 2 to the bottom support block 11, so that the adjusting seat 2 can be reliably maintained in the set position. Based on the bottom support seat 1, the adjusting seat 2 and the locking element 3 cooperate with each other, so that the cable laying direction can be quickly and accurately adjusted without adjusting the entire cable delivery device, which effectively improves construction efficiency and reduces labor intensity.

[0041] Specifically, the support leg 12 includes a strut 121 and a positioning block 122. One end of the strut 121 is fixed to the bottom support block 11, and the other end is fixed to the positioning block 122. The positioning block 122 is configured to support the placement surface. By setting the positioning block 122, the contact area between the support leg 12 and the placement surface is effectively increased, thereby improving the stability of the support leg 12.

[0042] More specifically, the positioning block 122 is provided with an anti-slip part 123 and / or a connecting part 124. The anti-slip part 123 is configured to support the placement surface, and the connecting part 124 is configured to be connected to the placement surface by fasteners. The above configuration further ensures the stability of the support leg 12.

[0043] More specifically, the bottom of the positioning block 122 is provided with an anti-slip part 123, which includes an anti-slip pad. The bottom side of the anti-slip pad is provided with multiple protruding structures. The anti-slip pad contacts the placement surface through the multiple protruding structures, thereby increasing the friction.

[0044] More specifically, a connecting part 124 is fixedly connected to one side of the positioning block 122. The connecting part 124 includes a connecting bracket, which is provided with a through hole. Fasteners such as bolts can be inserted into the through hole and anchored to the placement surface.

[0045] In this embodiment, the bottom support block 11 is cylindrical, and the axis of the bottom support block 11 is the adjustment axis. Three support legs 12 are provided at the bottom of the bottom support block 11. The three support legs 12 are evenly distributed around the axis of the bottom support block 11. Each support leg 12 is provided with a positioning block 122, and two connecting brackets are provided on opposite sides of each positioning block 122 in the lateral direction.

[0046] In other embodiments, the bottom of the base block 11 may also be provided with three or more support legs 12.

[0047] Specifically, the adjusting seat 2 includes an operating platform 21, a fixed shaft 22, and a support platform 23. The top of the bottom support block 11 is provided with a receiving groove, and the inner wall of the receiving groove is surrounded by a sliding groove 111. The operating platform 21 is rotatably disposed in the sliding groove 111. The support platform 23 is located on top of the operating platform 21 and is connected to the operating platform 21 via the fixed shaft 22. The support portion and the guide ring 201 are both disposed on the support platform 23. This configuration effectively increases the support area of ​​the bottom support block 11 on the adjusting seat 2, allowing the adjusting seat 2 to rotate more stably relative to the bottom support block 11.

[0048] More specifically, the support platform 23 includes a support plate 231 and a support plate 232. The support plate 231 is fixedly connected to the top of the fixed shaft 22, and the support plate 232 is detachably connected to the top side of the support plate 231. The support portion is disposed on the top surface of the support plate 232, and the guide ring 201 is fixedly mounted on the support plate 232. This configuration allows for convenient replacement of the support plate 232, thus adapting to the needs of cable reels 100 of different specifications and sizes, and enabling timely replacement when the support plate 232 wears out.

[0049] More specifically, the support plate 232 is elongated, and two rows of guide rings 201 are arranged. The two rows of guide rings 201 are parallel to each other and spaced apart along the width direction of the support plate 232. The cable outlets of the two rows of guide rings 201 are arranged opposite to each other. Multiple guide rings 201 in each row are arranged sequentially and spaced apart along the length direction of the support plate 232. The above arrangement allows the cable to be adjusted in a timely and convenient manner to exit through the guide rings 201 that meet the requirements, according to actual needs.

[0050] More specifically, the bearing part includes a crossbar 202, the cable reel 100 is rotatably mounted on the top surface of the bearing plate 232 via the crossbar 202, the guide ring 201 is annular and fixed on the top surface of the bearing plate 232, the axes of the multiple guide rings 201 are all parallel to the first horizontal direction, one side port of the guide ring 201 is the cable inlet and the other side port is the cable outlet.

[0051] In this embodiment, the support part includes two triangular support plates 203 disposed on the top surface of the support plate 232. The two triangular support plates 203 are spaced apart along the length direction of the support plate 232, and the top of each is provided with a support groove. The crossbar 202 passing through the cable reel 100 can be mounted in the two support grooves. When the cable in the cable reel 100 is led out from the guide ring 201, it drives the cable reel 100 to rotate relative to the crossbar 202.

[0052] Specifically, the adjusting seat 2 also includes an operating block 24. The bottom of the receiving groove is provided with a through hole, and the bottom of the fixed shaft 22 passes through the through hole to the bottom support block 11 and is connected to the operating block 24. By providing the operating block 24, it is easy to drive manually or by an external mechanism, so that the adjusting seat 2 can rotate safely.

[0053] More specifically, the operating block 24 is located on the bottom side of the bottom support block 11 and is positioned between multiple support legs 12, making it safer and more reliable and less susceptible to interference from external objects.

[0054] In this embodiment, the adjusting seat 2 also includes a motor and a gearbox that cooperate with each other. The motor is installed on the bottom side of the bottom support block 11, the motor shaft of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the operating block 24. The motor drives the operating block 24 to rotate stably through the gearbox.

[0055] Specifically, the adjusting base 2 is provided with an insertion port 20, and the locking element 3 includes an insertion rod 31. The insertion rod 31 is inserted into the insertion port 20 and can slide along the depth direction of the insertion port 20. The insertion port 20 interferes with the rotation of the insertion rod 31. When the insertion rod 31 slides along the depth direction of the insertion port 20, its position can be adjusted between the locked position and the unlocked position. The locking element 3 is inserted into the adjusting base 2, so that the locking element 3 can be used as an operating handle for manual operation by the user.

[0056] More specifically, the locking component 3 also includes a connecting rod 32 and a locking rod 33. The insert rod 31 and the locking rod 33 are located on the same side of the connecting rod 32. One end of the insert rod 31 is inserted into the insertion port 20, and the other end is connected to one end of the connecting rod 32. The other end of the connecting rod 32 is connected to one end of the locking rod 33, and the other end of the locking rod 33 is a locking head. This arrangement allows the locking component 3 to be precisely inserted into the insertion port 20 and the locking port 10.

[0057] Specifically, the locking port 10 is located on the outer peripheral wall of the base support block 11, and the opening of the insertion port 20 faces upward. The axis of the insertion port 20 and the axis of the locking port 10 are set at an angle. When the insertion rod 31 is inserted into the insertion port 20 to the locked position, the locking head is inserted into the locking port 10. When the insertion rod 31 is withdrawn from the insertion port 20 to the unlocked position, the locking head moves away from the insertion rod 31 under the support of the outer peripheral wall of the base support block 11, and the locking member 3 elastically deforms. The above arrangement makes the locking member 3 better clamping and locking the base support block 11 in the locked position. At this time, when the adjusting seat 2 is subjected to excessive force and rotates, the locking member 3 can be withdrawn from the locking port 10 through elastic deformation, avoiding damage to the locking member 3 due to force.

[0058] More specifically, the locking port 10 is located on the outer wall of the bottom support block 11 and is connected to the sliding groove 111 inside the bottom support block 11. Lubricating oil can be injected into the sliding groove 111 through the locking port 10, so that the operating table 21 can rotate more smoothly relative to the bottom support block 11. The insertion port 20 is located on the top surface of the operating table 21 to avoid interfering with the cable reel 100 on the support platform 23.

[0059] In this embodiment, the cross-section of the insertion port 20 and the cross-section of the insertion rod 31 are matched, both being non-circular structures such as elliptical or rectangular shapes, so that when the insertion port 20 is in place, the insertion rod 31 cannot rotate around its own axis.

[0060] In other embodiments, the opening directions of the locking port 10 and the insertion port 20 may be the same. For example, the openings of the locking port 10 and the insertion port 20 may both face upwards, so that when the insertion rod 31 is inserted into the insertion port 20, the locking rod 33 is simultaneously inserted into the locking port 10.

[0061] In other embodiments, the locking member 3 may also include only the insert rod 31, one end of which is connected to the adjusting seat 2 by a spring to form a plunger structure. In this case, the free end of the insert rod 31 is the locking head. During the rotation of the adjusting seat 2, the insert rod 31 is aligned with multiple locking ports 10 in sequence. When the insert rod 31 is aligned with a locking port 10, the locking head extends into the locking port 10 under the drive of the spring.

[0062] In practical use, the cable delivery device of this embodiment first supports multiple support legs 12 on the placement surface, so that the anti-slip part 123 fits against the placement surface. The connecting part 124 is connected to the placement surface by fasteners. The locking member 3 is in the locked position, and the locking head of the locking member 3 extends into a locking port 10. Then, the cable reel 100 is rotated on the support part of the support plate 232 via the crossbar 202. After that, the cable in the cable reel 100 is led out from the guide ring 201 for laying. When it is necessary to adjust the laying direction, first pull the locking member 3 upward so that the locking head of the locking member 3 exits from the locking port 10. Then rotate the adjusting seat 2 so that the cable lead-out direction is adjusted to the set direction. Then press the locking member 3 downward so that the locking head of the locking member 3 extends into the locking port 10. Then guide the cable out in this direction.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
