Description

Technical Field

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

[0002] Power engineering refers to the engineering related to the production, transmission, and distribution of electric energy. In a broad sense, it also includes the engineering of applying electricity as power and energy in multiple fields. Cables are a general term for optical cables, electric cables, etc. Cables are important items for controlling installations, connecting devices, and transmitting electric power, and are indispensable items in power engineering. Cable connection in power engineering is a basic process in electrical work and is also a very important process, which refers to the process of sequentially connecting cables section by section to form a continuous cable line, mainly including the connection of cable cores and the connection of sheaths.

[0003] When staff connect cables, they need to perform a series of connection operations such as removing the protective sleeve of the cable, connecting two cables together, putting on a new rubber sleeve, and heat shrinking. The operation is complex and time-consuming. Throughout the process, it is always necessary to hold and fix with one hand, and operate with one hand. Moreover, the above operation process needs to be carried out at high altitude. During the connection process at high altitude, weather factors such as strong winds can easily cause the cables to shake (among them, when the temperature rises in summer, the cables will become longer, resulting in too large a sag, and the shaking will be greater under the excitation of wind force), affecting the connection efficiency.

[0004] Therefore, we have developed a new cable connection device for power engineering. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0029] As Figure 1 - Figure 4 shown, the embodiment of the present invention provides a cable connection device for a power engineering cable, including a fixed pole 1 and a mounting member 2 sleeved and fixedly connected to the outer surface of the fixed pole 1. One end of the mounting member 2 is fixedly connected to a mounting plate 3. A U-shaped plate 6 is slidably connected to the top of the mounting plate 3. Among them, a chute 4 matching the U-shaped plate 6 is provided on the upper surface of the mounting plate 3. A regulating mechanism is installed on the top of the U-shaped plate 6, and a lower clamping plate 13 is fixedly connected to the top of the regulating mechanism. Two extension plates 14 are symmetrically and fixedly connected to both sides of the outer surface of the lower clamping plate 13, and a clamping mechanism is jointly installed on the tops of the two extension plates 14.

[0030] As Figure 2 shown, the regulating mechanism includes a bidirectional lead screw 8 rotatably connected through the inside of the U-shaped plate 6. One end of the bidirectional lead screw 8 penetrates and extends to the outside of the U-shaped plate 6 and is fixedly connected to a knob 7. Threaded sleeves are symmetrically sleeved on the outer surface of the bidirectional lead screw 8 and are threadedly connected to sliders 9. The lower surfaces of the two sliders 9 are both slidably connected to the inside of the U-shaped plate 6, and the tops of the two sliders 9 are both fixedly connected to fixed seats 10. Connecting rods 11 are hinged to the tops of the two fixed seats 10. One ends of the two connecting rods 11 are jointly hinged to a mounting seat 12, and the top of the mounting seat 12 is fixedly connected to the lower surface of the lower clamping plate 13;

[0031] By rotating the knob 7, the rotation of the bidirectional lead screw 8 is driven. When the bidirectional lead screw 8 rotates, the two sliders 9 on its surface will slide along the inside of the U-shaped plate 6, approaching or moving away from each other. The change in the distance between the two sliders 9 will drive the change in the included angle between the two connecting rods 11 connected above them, and change the vertical height of the mounting seat 12, so that the height of the upper clamping mechanism changes;

[0032] Among them, one fixed seat 10 is fixedly connected to the front side of the upper surface of the corresponding slider 9, and the other fixed seat 10 is fixedly connected to the rear side of the upper surface of the corresponding slider 9. The end parts of the two connecting rods 11 respectively connected to the two fixed seats 10 are hinged to the front side of the outer surface and the rear side of the outer surface of the mounting seat 12, so that the front and rear of the mounting seat 12 can be in a balanced state, thereby ensuring the stability of the upper clamping mechanism.

[0033] As Figure 3 shown, the clamping mechanism includes screws 17 respectively passing through and rotatably connected to the side walls of two extension plates 14. A connecting plate 16 is sleeved on the tops of the two screws 17. Sleeve pieces 19 are fixedly connected to the rear sides of the outer surfaces of the connecting plate 16 and the lower clamping plate 13. The two sleeve pieces 19 are arranged oppositely, that is, the two sleeve pieces 19 clamp the upper and lower surfaces of the cable respectively. Since the distance between the two sleeve pieces 19 is not fixed, by placing the connecting plate 16 above the cable and pressing it down while aligning with the screw 17, the sleeve pieces 19 are arranged above and below the cable to clamp it, and cables of different thickness specifications can be clamped, improving the scope of application;

[0034] External threads 25 are provided on the tops of the outer surfaces of the two screws 17, and nuts 18 are sleeved and threadedly connected to the tops of the two screws 17. The lower surfaces of the two nuts 18 are in contact with the upper surface of the connecting plate 16. By turning the nuts 18, the nuts 18 will squeeze the connecting plate 16 downward, thereby changing the position of the connecting plate 16 and the sleeve piece 19 above it connected thereto. The two sleeve pieces 19 approach each other, and the clamping of the cable can be achieved.

[0035] Spring 15 is fixedly connected to the upper surfaces of the two extension plates 14. The two springs 15 are respectively sleeved outside the corresponding screws 17, and the tops of the two springs 15 are in contact with the lower surface of the connecting plate 16. The presence of the spring 15 prevents the connecting plate 16 from directly moving downward when installed on the top of the screw 17 and thus engaging with the extension plate 14. Moreover, due to the elastic limit of the spring 15 itself, it limits the minimum distance between the connecting plate 16 and the extension plate 14 to not be less than the minimum length when the spring 15 is compressed.

[0036] A sliding plate 5 is fixedly connected to the bottom of the front side of the outer surface of the U-shaped plate 6. A locking pin 20 is threadedly connected through the bottom side wall of the sliding plate 5. A contact block 21 is fixedly connected to the end of the locking pin 20, and the upper surface of the contact block 21 is in contact with the lower surface of the mounting plate 3. Among them, a rubber pad is fixedly connected to the upper surface of the contact block 21, which can increase the friction between the contact block 21 and the mounting plate 3. When the locking pin 20 is turned so that the contact block 21 at its end is in close contact with the lower surface of the mounting plate 3, the presence of the rubber pad makes it more difficult for the two to slip.

[0037] The working principle of the operation process of this embodiment is as follows: The connecting plate 16 is not initially sleeved on the top of the screw. First, the mounting member 2 (the mounting member 2 can be in the form of a hoop, which is convenient to be sleeved and assembled on the outer surface of the fixed wire rod for fixation) is fixed on the outer surface of the fixed wire rod 1. Subsequently, the staff can first move the position of the U-shaped plate 6 and tighten the locking pin 20 when it is directly below the cable, and preliminarily determine the positions of the adjusting mechanism and the clamping mechanism corresponding to the cable;

[0038] Subsequently, turn the knob to adjust the height of the mounting base 12 so that the lower clamping plate 13 is close to the lower side of the cable. Then, place the connecting plate 16 above the cable and press it down while aligning it with the screw 17, so that the sleeve pieces 19 are arranged above and below the cable to clamp it. Moreover, the sleeve pieces 19 have a certain length. In windy weather outdoors, etc., they can limit the cable within a larger range, ensure the stability of the operation section of the staff, reduce shaking. At the same time, the staff does not need to always hold and fix it with one hand, and both hands can perform operations such as removing the protective sleeve and cable wiring mixing, thereby improving the mating efficiency. Specific Embodiment 2

[0040] Please refer to Figure 5 , on the basis of Specific Embodiment 1, specifically, the clamping mechanism includes screws 17 respectively penetrating and rotatably connected to the side walls of the two extension plates 14. A first support plate 22 is sleeved on the top of a single screw 17, and a second support plate 23 is sleeved on the top of the other screw 17. One end of the second support plate 23 is hinged to the first support plate 22, and a relief groove 24 matching the screw 17 is formed in the side wall of the second support plate 23. Sleeve pieces 19 are fixedly connected to the outer surfaces of the rear sides of the second support plate 23 and the lower clamping plate 13. The two sleeve pieces 19 are arranged oppositely, and the upper and lower surfaces of the cable are clamped by the two sleeve pieces 19 respectively. Moreover, since the distance between the two sleeve pieces 19 is not fixed, cables of different thickness specifications can be clamped, improving the applicable range;

[0041] External threads 25 are formed on the outer surfaces of the tops of the two screws 17, and nuts 18 are sleeved and threadedly connected to the tops of the two screws 17. The lower surfaces of the two nuts 18 are abutted against the upper surface inside the connecting plate 16. By screwing the nuts 18 to squeeze the first support plate 22 and the second support plate 23 downward, the position of the sleeve piece 19 above can be changed. When the two sleeve pieces 19 approach each other, clamping of the cable can be achieved.

[0042] The working principle of the operation process of this embodiment is as follows: When clamping and fixing the cable, there is no need for another component to press down above the cable (such as the up-and-down alignment combination method in Embodiment 1), but through the up-and-down hinged combination method, the whole clamping mechanism is more integrated, which is convenient for the staff to operate at high altitude and prevents parts from falling and getting lost. In its initial state, the second support plate 23 is turned outwards, so that the cable can be placed above the lower clamping plate 13. Then, rotate the second support plate 23 around the hinge point with the first support plate 22, so that the top of the screw 17 passes through the relief groove 24 of the second support plate 23, and the initial fixation of the cable by the sleeve pieces 19 from above and below can be realized. Then, by screwing the nuts 18, the cable can be clamped by the sleeve pieces 19.

[0043] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
