Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to an electric power construction guide frame. Background Art

[0002] The power construction process often involves the laying of cables. Before being transported to the construction site, the cables are wound on the outside of the cable drum. After being transported to the power construction site, the cable drum needs to be erected through the power construction guide frame, and then the cables are pulled out and released from the cable drum for laying;

[0003] The patent document with the publication number of "CN220086816U" discloses "a kind of electric power construction guide frame. In view of the existing guiding problems, the following scheme is proposed, which includes a guide frame, a guide hole is opened on one side of the guide frame, a fixed block is fixedly installed on the bottom inner wall of the guide hole, and a guide wheel is rotatably installed in the guide hole. A guide wheel is arranged in the guide frame, which can effectively avoid the friction between the cable and the guide frame, causing damage to the cable". Although "it effectively avoids the friction between the cable and the guide frame, causing damage to the cable", in the actual electric power construction process, when the ambient temperature is low, the cable will become brittle and hard. At this time, the flexibility of the cable is insufficient, so it is easy to be damaged during the laying process. When the cable is laid in the underground tunnel, the cable is first vertically downward and then bent 90° before it can enter the tunnel for laying. The above-mentioned corresponding guidance cannot be performed. Therefore, when the cable is bent, it is easy to rub against the inside of the tunnel, causing the outside of the cable to be damaged due to wear. Summary of the invention

[0052] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0053] like Figure 1-Figure 12 As shown, a guide frame for electric power construction, please refer to Figure 1 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 , comprising a carrying mechanism 1, a mounting frame 2 for mounting a cable drum is arranged at the rear of the top of the carrying mechanism 1, a plurality of balls 8 are rollingly connected to the top of the mounting frame 2, a heating mechanism 3 for heating the cable is arranged in the center of the top of the carrying mechanism 1, an extension mechanism 4 is arranged at the front end of the carrying mechanism 1, a direction adjustment mechanism 5 for adjusting the direction of the cable is arranged at the upper end of the front end of the extension mechanism 4, and a guide mechanism 6 for changing the direction of the cable is arranged at the lower end of the front end of the extension mechanism 4;

[0054] The heating mechanism 3 includes a carrying frame 301, a plurality of fans 302 are fixedly installed on the top of the carrying frame 301, a plurality of electric heating rods 308 are installed between the two side frames of the carrying frame 301 and below the fans 302, the guiding mechanism 6 includes a roller frame 601, a plurality of guide rollers 602 are movably installed between the upper and lower end frames of the roller frame 601, an adjusting groove 607 is opened in the rear end frame of the roller frame 601, an adjusting plate 608 is slidably connected inside the adjusting groove 607, and a connecting shaft 604 is fixedly installed on the other side of the adjusting plate 608;

[0055] Specifically, during power construction, the cable drum is erected on the top of the erection frame 2, and the cable is pulled out and passed through the mounting frame 301. The friction between the cable drum and the erection frame 2 is reduced by the ball bearing 8, so that the cable drum can roll and release the cable. After the fan 302 and the electric heating rod 308 are started, hot air is blown to the cable to heat it. When the ambient temperature is low, the cable is heated to maintain a certain flexibility, so as to avoid the cable skin being brittle and hard in the low temperature environment, which may cause damage to the cable during the construction process. After the cable is pulled out from the mounting frame 301, it is erected on the adjustment mechanism 5. The direction of the cable is adjusted to facilitate the cable to adapt to the laying surface in different positions. At the same time, when the cable is laid underground, the connecting shaft 604 is rotated to drive the adjustment plate 608 to rotate. The adjustment plate 608 rotates and drives the roller frame 601 to rotate synchronously, so that the roller frame 601 rotates from a horizontal state to a vertical state. After rotating to the vertical state, the roller frame 601 goes deep into the ground, and then the cable passes through the guide roller 602. The guide roller 602 is used to change the direction of the cable, which is convenient for laying the cable underground and avoids contact with the inner wall of the underground tunnel during the laying process, causing wear during the movement of the cable.

[0056] Please refer to Figure 1 , Fig.11 and Fig.12 The heating mechanism 3 also includes a second limiting slide groove 306 that passes through the frame bodies on both sides of the carrying frame 301, a bottom carrying frame 304 located between the frame bodies on both sides of the carrying frame 301 and slidably connected to the second limiting slide groove 306, and lower anti-friction rollers 305 are movably installed at the top and front and rear ends of the top of the bottom carrying frame 304, and upper anti-friction rollers 303 are movably installed at the top and front and rear ends between the frame bodies on both sides of the carrying frame 301, and springs 307 are fixedly installed at the top of the bottom carrying frame 304 on both sides and inside the second limiting slide groove 306.

[0057] Specifically, when the cable passes through the carrying frame 301, it passes between the upper anti-friction roller 303 and the lower anti-friction roller 305, and the bottom carrying frame 304 is pushed by the spring 2 307. The upper anti-friction roller 303 cooperates with the lower anti-friction roller 305 to limit the cable, which is convenient for limiting cables of different diameters. At the same time, the upper anti-friction roller 303 and the lower anti-friction roller 305 prevent the cable from being subjected to large friction during movement, which may cause wear on the cable sheath.

[0058] Please refer to Figure 1 , Fig. 9 and Fig.10 The guide mechanism 6 also includes a stepper motor 606, and a coupling 605 is installed on the outer ring of the output shaft of the stepper motor 606. The connecting shaft 604 is fixedly connected to the output shaft of the stepper motor 606 through the coupling 605, and a knob bolt 603 is threadedly connected to the top of the roller frame 601 and located at the top of the adjustment plate 608.

[0059] Specifically, when the roller frame 601 is in a horizontal state, the knob bolt 603 is tightened to fix the steering plate 608 to facilitate limiting the position of the roller frame 601. After loosening the knob bolt 603, the stepper motor 606 starts to drive the coupling 605 to rotate, and then drives the connecting shaft 604 to rotate. The steering plate 608 is driven to rotate by the rotating connecting shaft 604. When the steering plate 608 rotates and drives the roller frame 601 to rotate to a vertical state, the roller frame 601 slides into the laying pit dug underground, so that the guide roller 2 602 and the underground laying tunnel are in the same horizontal plane. The guide roller 2 602 changes the direction of the cable and limits the cable to avoid contact between the cable and the inner wall of the tunnel, which causes the cable to wear during movement.

[0060] Please refer to Figure 1 and Figure 2 The transport mechanism 1 includes a transport base 101, driving wheels 102 are installed on both sides of the transport base 101 near the front and rear ends, two extension grooves 103 are opened in the center of the top of the transport base 101, cylinder grooves 104 are opened on both sides of the front end of the transport base 101, and the bottoms of the carrying frame 301 and the erection frame 2 are fixedly connected to the top of the transport base 101.

[0061] Specifically, the driving wheel 102 drives the carrier base 101 to move, so as to facilitate driving the electric power construction guide frame to move, and facilitate moving the electric power construction guide frame to the construction site.

[0062] Please refer to Figure 1 and Figure 3 The extension mechanism 4 includes a carrying box 401, a shaft groove 404 is opened on the front side of the carrying box 401 near the top, a mounting groove 405 is opened on the top surface of the carrying box 401, two extension slide rails 402 are fixedly installed on the back side of the carrying box 401 near the bottom and in the center, a cylinder 403 is installed on the back side of the carrying box 401 near the bottom and on both sides, the piston of the cylinder 403 is fixedly connected to the carrying box 401, anti-friction rollers 406 are installed on the top of the carrying box 401 near the front and rear ends, and a stepper motor 606 runs through the front end of the carrying box 401 and is fixedly connected to the carrying box 401.

[0063] Specifically, after the cylinder 403 is started, it drives the carrying box 401 to move forward. When the cable needs to be laid in the underground tunnel, the forward-moving carrying box 401 can be used to move the adjustment mechanism 5 and the guide mechanism 6 to the top of the tunnel to facilitate the lowering of the cable. At the same time, when the cable is installed to the top of the carrying box 401, the friction force on the cable is reduced by the anti-friction roller 406 to avoid wear during the movement of the cable.

[0064] Please refer to Figure 1 and Figure 3 The cylinder 403 is located inside the cylinder groove 104 , and the cylinder body of the cylinder 403 is fixedly connected to the carrier base 101 , the extension slide rail 402 is located inside the extension groove 103 , and the extension slide rail 402 is slidably connected to the carrier base 101 through the extension groove 103 .

[0065] Specifically, when the cylinder 403 is started and drives the carrying box 401 to move forward, the extension rail 402 slides forward along the direction of the extension groove 103, and the extension rail 402 shares the pressure on the piston of the cylinder 403, thereby preventing the piston of the cylinder 403 from being damaged due to excessive pressure.

[0066] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The direction adjustment mechanism 5 includes a mounting assembly 51 and a limiting assembly 52. ​​The mounting assembly 51 includes a mounting frame 5101. A mounting shaft 5102 is fixedly installed in the center of the back of the mounting frame 5101. The mounting shaft 5102 is located inside the shaft groove 404, and the mounting shaft 5102 is movably connected to the carrying box 401 through a bearing. A chuck 5103 is arranged on the inner wall of the frame on both sides of the mounting frame 5101. A disk shaft 5105 is fixedly installed in the center of one side of the chuck 5103, and the disk shaft 5105 is movably connected to the mounting frame 5101 through a bearing. A plurality of guide rollers 5104 are movably installed between the two chucks 5103. The plurality of guide rollers 5104 are arranged in a ring shape, and a mounting groove 2 5106 is opened at the top of the frame on both sides of the mounting frame 5101.

[0067] Specifically, during the construction process, when the cable passes over the anti-friction roller 406 and is installed on the guide roller 5104, when the installation frame 5101 rotates around the frame axis 5102, it drives the chuck 5103 and the guide roller 5104 to rotate to different positions, and at the same time cooperates with a number of guide rollers 5104 to guide the cable, so that the cable can extend in different directions and adapt to laying surfaces at different angles.

[0068] Please refer to Figure 1 , Figure 4 and Figure 6The limiting assembly 52 includes a limiting frame 5201 fixedly installed on the top of the chuck 5103, spring boxes 5202 are fixedly installed on both sides of the top of the limiting frame 5201, a spring 5207 is fixedly installed inside the spring box 5202, a pull bolt 5203 is movably installed in the center of the top frame body passing through the limiting frame 5201, a roller frame 5204 is fixedly installed at the bottom of the pull bolt 5203, a limiting roller 5205 is movably installed between the two side frames of the roller frame 5204, a limiting slide groove 5206 is provided on the two side frames passing through the limiting frame 5201, the roller frame 5204 is slidably connected to the limiting frame 5201 through the limiting slide groove 5206, and the bottom end of the spring 5207 is fixedly connected to the top of the roller frame 5204.

[0069] Specifically, pulling the pull bolt 5203 upward drives the roller frame 5204 and the limiting roller 5205 to rise synchronously, and then the cable is passed through between the limiting roller 5205 and the guide roller 5104, and the roller frame 5204 is pressed down by the spring 5207, driving the limiting roller 5205 to press the cable to the outside of the guide roller 5104, so as to clamp the cables of different directions and prevent the cable from escaping from the guide roller 5104 during the movement.

[0070] Please refer to Figure 5 , Figure 7 and Figure 8 The brake shaft mechanism 7 is installed inside the mounting groove 1 405 and the mounting groove 2 5106 .

[0071] Please refer to Figure 7 The brake shaft mechanism 7 includes a brake shaft block 701, and limit blocks 702 are fixedly installed on both sides of the brake shaft block 701. An electric telescopic rod 703 is installed at the rear end of the brake shaft block 701, and the piston rod of the electric telescopic rod 703 is fixedly connected to the brake shaft block 701.

[0072] Specifically, after the electric telescopic rod 703 is started, it drives the brake shaft block 701 to move. When the brake shaft block 701 presses against the frame shaft 5102 and the disk shaft 5105 during the movement, the frame shaft 5102 and the disk shaft 5105 can be limited to prevent the frame shaft 5102 and the disk shaft 5105 from rotating.

[0073] How it works

[0074] When carrying out power construction, the cable drum is erected to the top of the erection frame 2, and the cable is pulled out and passed through the carrying frame 301. The friction between the cable drum and the erection frame 2 is reduced by the ball 8, so that the cable drum can roll and release the cable. The upper anti-friction roller 303 and the lower anti-friction roller 305 cooperate with the spring 2 307 to limit the cable. After the fan 302 and the electric heating rod 308 are started, hot air is blown to the cable to heat it. When the ambient temperature is low, the cable is heated to maintain a certain flexibility of the cable to avoid the brittleness of the cable skin in the low temperature environment, which may cause damage to the cable during the construction process. After the cable is pulled out from the carrying frame 301, it is erected on the guide roller 1 5104, and then the cable is passed between the limiting roller 5205 and the guide roller 1 5104, and the cable is limited by the spring 1 5207, so as to clamp cables of different directions and prevent the cable from escaping from the guide roller 1 5101 during movement. 04, and then the angle of the guide roller 1 5104 is adjusted by rotating the erection frame 5101, so that the cable can extend in different directions and adapt to the laying surfaces at different angles. After the adjustment is completed, the frame shaft 5102 is limited by the brake shaft mechanism 7, so that the erection component 51 is fixed at the specified angle. At the same time, when the cable is laid underground, the stepper motor 606 is started to cooperate with the coupling 605 to drive the connecting shaft 604 to rotate, and the direction adjustment plate 608 is driven to rotate through the connecting shaft 604. When the direction adjustment plate 608 rotates, the roller frame 601 is driven to rotate synchronously, so that the roller frame 601 rotates from a horizontal state to a vertical state. After rotating to a vertical state, the roller frame 601 goes deep into the ground, and then the cable passes through the guide roller 2 602, and the guide roller 2 602 is used to change the direction of the cable, so as to facilitate the laying of the cable underground and avoid contact with the inner wall of the underground tunnel during the laying process, which causes wear during the movement of the cable.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
