DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] During the laying of electrical cables in a thermal power plant, a wiring support and protection device is required to support and protect the cables and their joints. The wiring support and protection device provided by the utility model facilitates the rapid replacement of worn clamping blocks 5.

[0022] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a thermal power plant electrical wiring support and protection device, including a mounting shell 1, a lifting mechanism 2 is arranged inside the mounting shell 1, a mounting frame 3 is arranged at the top of the lifting mechanism 2, two moving rods 4 are slidably connected to the inner walls of both sides of the mounting frame 3, a clamping block 5 is fixed on the side where the two moving rods 4 in each inner wall are close to each other, a connecting rod 6 is fixed on one side of the clamping block 5, slots 7 are provided on both sides of the connecting rod 6, a connecting groove is provided on one side of the moving rod 4, the connecting rod 6 is plugged into the connecting groove, and fixing mechanisms 8 are provided at both ends of the connecting rod 6, and the fixing mechanism 8 includes a through-insertion A connecting plate 806 is fixed to the outer wall of the fixed shell 802 on both sides of the inner wall of the connecting rod 6, and bolts are fixed between the connecting plate 806 and the outer wall of the movable rod 4. A slide plate 805 is slidably connected to the inner wall of the fixed shell 802. A limit block 804 is fixed to the ends of the two slide plates 805 that are close to each other. The limit block 804 is inserted into the slot 7. A pull rod 801 is fixed to the ends of the two slide plates 805 that are away from each other. The pull rod 801 penetrates and is slidably connected in the fixed shell 802. A spring 803 is fixed to the ends of the two slide plates 805 that are away from each other. The spring 803 is fixed to the inner wall of the fixed shell 802.

[0023] It should be noted that by moving the connecting rod 6 downward and inserting it into the connecting groove, the limit block 804 contacts the outer wall of the connecting rod 6 during the insertion process and squeezes the limit block 804, so that the spring 803 is compressed. When the connecting rod 6 moves to the bottom of the connecting groove, the spring 803 drives the limit block 804 to move forward, so that the limit block 804 is inserted into the slot 7 to fix the clamp 5.

[0024] like Figure 1 and Figure 4 As shown, connecting members 14 are fixed to the inner walls of both sides of the mounting frame 3, and sliders 13 are slidably connected to the outer walls of both ends of the connecting members 14, and a connecting rod 12 is rotatably connected to one side of the slider 13, and two fixing members 15 are fixed between the top inner wall and the bottom inner wall of the mounting frame 3, and sliding blocks 11 are slidably connected to the two fixing members 15 on the sides away from each other, and the connecting rod 12 is rotatably connected to the sliding block 11, and a fixing rod 10 is fixed between the two sliding blocks 11. A telescopic rod 9 is fixed to the inner wall of the bottom end of the mounting frame 3, and the telescopic end of the telescopic rod 9 is fixed to the fixing rod 10. The lifting mechanism 2 includes a screw rod 204 rotatably connected between the top inner wall and the bottom inner wall of the installation shell 1, a sliding rod 201 is screwed to the outer wall of the screw rod 204, a limit rod 203 is fixed between the top inner wall and the bottom inner wall of the installation shell 1, the sliding rod 201 penetrates and slides through the outer wall of the limit rod 203, a support rod 202 is fixed to the top of the sliding rod 201, and the support rod 202 penetrates the installation shell 1 and is fixed to the bottom end of the installation frame 3. A motor is fixed to the bottom end of the installation shell 1, and the output end of the motor penetrates the installation shell 1 and is fixed to the bottom end of the screw rod 204. The motor has a self-locking function, and a support frame is installed at the bottom end of the installation shell 1. A controller is installed on one side of the installation shell 1, and the controller is electrically connected to the motor and the telescopic rod 9.

[0025] It should be noted that the telescopic rod 9 drives the fixed rod 10 to move upward, the fixed rod 10 drives the sliding block 11 to move upward, and the sliding block 11 drives the connecting rod 12 to move, so that the two sliders 13 move in a direction close to each other, thereby clamping the cable. In addition, when the telescopic rod 9 drives the fixed rod 10 to move downward, the sliding block 11 moves downward, and the sliding block 11 drives the connecting rod 12 to move, so that the two sliders 13 move in a direction away from each other and no longer clamp the cable.

[0026] Working principle: When the clamping block 5 needs to be replaced, the pull rod 801 is pulled outward to compress the spring 803, which can drive the slide plate 805 and the limit block 804 to move, so that the limit block 804 moves out of the slot 7 and no longer fixes the clamping block 5. Then, the connecting rod 6 on one side of the replaced clamping block 5 moves downward and is inserted into the connecting groove. During the insertion process, the limit block 804 contacts the outer wall of the connecting rod 6 and squeezes the limit block 804, so that the spring 803 is compressed. When the connecting rod 6 moves to the bottom of the connecting groove, the spring 803 drives the limit block 804 to move forward, so that the limit block 804 is inserted into the slot 7 to fix the clamping block 5.
