Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and specifically relates to a cable laying device. Background Art

[0002] Electric wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electrical and magnetic energy. In a broad sense, electric wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as a collective body composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, general protective layers, and outer protective layers. A cable can also have additional non-insulated conductors.

[0003] When laying cables at high altitudes, a lifting device is required to lift the cables to the installation rack. However, in some special sections, such as sections with limited space, the lifting device cannot enter this section to lift the cables. At this time, it is usually necessary for workers to hold telescopic rods manually for lifting. During the lifting process, multiple people need to cooperate, which is relatively cumbersome. Or the operators on the installation rack lift the cables to the appropriate position through ropes, but during the lifting process, accidents are likely to occur. Summary of the Invention

Detailed implementation manners

[0044] To more clearly illustrate the overall concept of the present invention, the following will be further described in detail by way of examples in conjunction with the accompanying drawings of the specification. Embodiment

[0045] Please refer to Figures 1 to 15 , the present invention provides a technical solution: a cable laying device, including:

[0046] A moving trolley 1, on which a fixed plate 2 is installed, and a moving plate 3 is slidably installed on the fixed plate 2;

[0047] A telescopic assembly, installed on the moving plate 3, and the telescopic assembly includes a first sleeve 4;

[0048] A transmission assembly, installed at a position of the moving plate 3 corresponding to the first sleeve 4, and the transmission assembly includes a motor 7;

[0049] The telescopic assembly lifts the cable inside the fixed ring 5 to an appropriate height, and at the same time, the transmission assembly adjusts the position of the moving plate 3 relative to the fixed plate 2 to finely adjust the cable inside the fixed ring 5, so as to automatically lift the cable to an appropriate height. Embodiment

[0050] As Figures 4 - 9 shown, the cable laying device disclosed in the second embodiment of the present invention has basically the same structure as that in the first embodiment, and the difference lies in:

[0051] The telescopic assembly includes a first threaded rod 8, which is composed of a smooth rod at the lower end and a threaded rod at the upper end, and the smooth rod part of the first threaded rod 8 is rotatably connected to the moving plate 3. A first sleeve 4 is sleeved outside the first threaded rod 8, and the bottom of the first sleeve 4 is fixedly connected to the moving plate 3;

[0052] A plurality of second sleeves 13 are arranged between the first threaded rod 8 and the first sleeve 4. The plurality of second sleeves 13 are hollow cylindrical and sleeved together in sequence, and are concentric with the first sleeve 4 and the first threaded rod 8;

[0053] A fixing ring 5 is fixedly arranged on the upper end surface of the innermost second sleeve 13;

[0054] The bottom of each second sleeve 13 is in fit with the thread provided on the threaded rod part of the first threaded rod 8 in sequence;

[0055] A guiding assembly is arranged between the plurality of second sleeves 13 for guiding each second sleeve 13 to lift successively;

[0056] The guiding assembly includes a second guiding groove 17 which is opened on the inner walls of the first sleeve 4 and the plurality of second sleeves 13 between the first sleeve 4 and the innermost second sleeve 13;

[0057] At the position of the second sleeve 13 corresponding to the second guiding groove 17, a first guiding block 23 is arranged. The first guiding block 23 is slidably arranged inside the second guiding groove 17, and first receiving grooves 18 are opened at the top ends of the inner walls of the plurality of second guiding grooves 17. A clamping block 19 is inserted inside the first receiving groove 18. The outer lower end surface of the clamping block 19 is in an inclined plane shape, and a first elastic member 20 is arranged between the first receiving groove 18 and the clamping block 19. The clamping block 19 is elastically inserted inside the first receiving groove 18 through the first elastic member 20. The distance between the top of the second guiding groove 17 and the top of the first receiving groove 18 matches the size of the first guiding block 23;

[0058] It further includes a releasing member for releasing the limit of the clamping block 19 on the first guiding block 23;

[0059] The releasing member includes a third receiving groove 28 which is opened on the lower end surface of the end of the second sleeve 13 perpendicular to the first threaded rod 8. A second abutting block 27 is inserted inside the third receiving groove 28. A third elastic member 29 is arranged between the second abutting block 27 and the third receiving groove 28. The second abutting block 27 is elastically inserted inside the third receiving groove 28 through the third elastic member 29;

[0060] A first through hole 22 is opened between each first receiving groove 18 and each corresponding third receiving groove 28. A first pulling rope 21 is arranged inside the first through hole 22. The two ends of the first pulling rope 21 are respectively connected to the second abutting block 27 and the clamping block 19, and the elastic force of the first elastic member 20 is greater than the elastic force of the third elastic member 29;

[0061] A second receiving groove 24 is formed at a position corresponding to the innermost second sleeve 13 on the first threaded rod 8. A first abutting block 26 is inserted into the second receiving groove 24. A second elastic member 25 is disposed between the second receiving groove 24 and the first abutting block 26. The first abutting block 26 is elastically inserted into the second receiving groove 24 through the second elastic member 25, and the elastic force of the second elastic member 25 is greater than the elastic force of the first elastic member 20, so as to limit the first guiding block 23 to abut against the lower end surface of the clamping block 19 and lift the corresponding second sleeve 13.

[0062] Install the cable into the fixing ring 5, and then drive the first threaded rod 8 to rotate. When the first threaded rod 8 rotates, due to the limiting cooperation of the first sleeve 4 and the first guiding block 23 and the second guiding groove 17 provided between the first sleeve 4 and the second sleeve 13, the innermost second sleeve 13 will rise along the first threaded rod 8, and the corresponding first guiding block 23 will slide along the second guiding groove 17 formed on the inner side of the adjacent second sleeve 13. When the innermost second sleeve 13 rises to a certain height, it will squeeze the elastically arranged clamping block 19, and then drive the adjacent second sleeve 13 to rise along the first threaded rod 8 through the cooperation of the first guiding block 23 and the second guiding groove 17. During the rising process, the elastically arranged second abutting block 27 is gradually no longer abutted. When the second abutting block 27 is ejected by the third elastic member 29, the first pulling rope 21 gradually becomes loose, and the elastically arranged clamping block 19 gradually extends out of the first receiving groove 18, so as to limit the first guiding block 23. After rising to a certain distance, the bottom of the lifted second sleeve 13 will be screwed to the outer surface of the first threaded rod 8, so that the lifted second sleeve 13 continues to rise along the first threaded rod 8, and the inner second sleeve 13 is connected to the lifted second sleeve 13, realizing the extension of multiple groups of second sleeves 13. Under the continuous rotation state of the first threaded rod 8, multiple groups of second sleeves 13 gradually extend and increase in height, thereby lifting the cable. Embodiment

[0063] As Figures 2 - 3 and Figures 10 - 15 shown, the cable laying device disclosed in Embodiment 3 of the present invention has basically the same structure as that in Embodiment 2, and the difference lies in that:

[0064] A clamping groove 6 is formed on the fixing plate 2, and the moving plate 3 is slidably disposed on the clamping groove 6.

[0065] Two groups of first racks 12 are installed on the clamping groove 6. The two groups of first racks 12 are symmetrically distributed, and each group of first racks 12 includes two. The two first racks 12 are respectively installed on the clamping groove 6 and the surface of the moving plate 3 corresponding to the clamping groove 6. A first gear 43 is arranged between the two first racks 12. One end of the first gear 43 is rotatably connected to a second rack 44. A first guiding groove 9 is opened at the position of the clamping groove 6 corresponding to the second rack 44. The second rack 44 is limited to move in the clamping groove 6 through the first guiding groove 9, and a second gear 45 is rotatably arranged at the position of the clamping groove 6 corresponding to the second rack 44;

[0066] The output end of the motor 7 penetrates through the moving plate 3 and is connected to a third gear 46, and the bottom of the first threaded rod 8 penetrates through the moving plate 3 and is connected to a fourth gear 47. The distance between the third gear 46 and the fourth gear 47 is matched with the distance between the third gear 46 and the second gear 45;

[0067] A third guiding groove 30 is opened at the position of the moving plate 3 corresponding to the motor 7. The third guiding groove 30 is in a "C" - shaped structure and penetrates through the moving plate 3 and is opened on the clamping groove 6. A second support rod 32 is inserted into the inside of the third guiding groove 30. The end of the second support rod 32 penetrates through the moving plate 3 and is connected to a fifth gear 55. The fifth gear 55 can enable the third gear 46 to drive the second gear 45 or the fourth gear 47 to rotate synchronously;

[0068] A collar 34 is slidably sleeved on the top of the second support rod 32. A fourth elastic member 35 is arranged between the collar 34 and the top of the second support rod 32. Two fixing rods 33 are installed at one end of the collar 34 away from the fourth elastic member 35. Matching fixing holes 31 are opened at the positions of the moving plate 3 corresponding to the two fixing rods 33. Three groups of fixing holes 31 are opened at intervals at the position of the moving plate 3 corresponding to the third guiding groove 30;

[0069] The telescopic assembly is installed on the moving plate 3, and the moving plate 3 is slidably arranged on the fixed plate 2. When the position of the telescopic assembly needs to be adjusted, the limit of the second rod 32 is released, and then the second rod 32 is moved, so that the second rod 32 moves along the third guiding groove 30. The second rod 32 will drive the fifth gear 55 to move. When the fifth gear 55 moves between the second gear 45 and the third gear 46, the third gear 46 will drive the second gear 45 to rotate through the fifth gear 55. When the second gear 45 rotates, it drives the second rack 44 to move. During the movement of the second rack 44, it drives the first gear 43 to move. When the first gear 43 is displaced, it drives the first rack 12 to extend, thereby driving the moving plate 3 to move, so that the telescopic assembly arranged on the moving plate 3 drives the cable to move;

[0070] When the fifth gear 55 moves between the third gear 46 and the fourth gear 47, the third gear 46 can drive the first threaded rod 8 to rotate.

[0071] The specific solution of this scheme is as follows: Move the mobile trolley 1 to the designated position, and then clamp the cable inside the fixed ring 5. After the movement is completed, start the motor 7. The motor 7 drives the fourth gear 47 to rotate through the cooperation of the third gear 46 and the fifth gear 55, and then drives the first threaded rod 8 to rotate. When the first threaded rod 8 rotates, due to the limiting cooperation of the first sleeve 4 and the first guiding block 23 and the second guiding groove 17 arranged between the first sleeve 4 and the second sleeve 13, the innermost second sleeve 13 will rise along the first threaded rod 8, and the corresponding first guiding block 23 will slide along the second guiding groove 17 opened on the inner side of the adjacent second sleeve 13. When the innermost second sleeve 13 rises to a certain height, it will squeeze the elastically arranged clamping block 19, and then drive the adjacent second sleeve 13 to rise along the first threaded rod 8 through the cooperation of the first guiding block 23 and the second guiding groove 17. During the rising process, the elastically arranged second abutting block 27 is gradually no longer abutted. When the second abutting block 27 is ejected by the third elastic member 29, the first pulling rope 21 gradually becomes loose, and the elastically arranged clamping block 19 gradually extends out of the first receiving groove 18, thereby limiting the first guiding block 23. And after rising to a certain distance, the bottom of the lifted second sleeve 13 will be screwed to the outer surface of the first threaded rod 8, so that the lifted second sleeve 13 continues to rise along the first threaded rod 8, and the inner second sleeve 13 is connected to the lifted second sleeve 13, realizing the extension of multiple groups of second sleeves 13. Under the continuous rotation state of the first threaded rod 8, multiple groups of second sleeves 13 gradually extend and increase in height, thereby lifting the cable;

[0072] When fine adjustment of the cable position is required, release the limit of the second support rod 32, and then move the second support rod 32 so that the second support rod 32 moves along the third guiding groove 30. The second support rod 32 will drive the fifth gear 55 to move. When the fifth gear 55 moves between the second gear 45 and the third gear 46, the third gear 46 will drive the second gear 45 to rotate through the fifth gear 55. When the second gear 45 rotates, it drives the second rack 44 to move. During the movement of the second rack 44, it drives the first gear 43 to move. When the first gear 43 is displaced, it drives the first rack 12 to extend, thereby driving the moving plate 3 to move, and enabling the telescopic assembly provided on the moving plate 3 to drive the cable to move.

[0073] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this invention shall be included within the protection scope of this invention.
