[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] like Figures 3 to 5 As shown, the embodiment of the present invention is a fixing device for installing equipment in a thermal power plant with a limit clamping mechanism, comprising a chuck 1; a clamping block 2 is provided at the bottom of the chuck 1; an internal spring 3 is fixedly connected to the inside of the chuck 1, and a plurality of the internal springs 3 are distributed in a circular array; the end of the internal spring 3 is fixedly connected to a limit rod 4; the top of the chuck 1 is fixedly connected to a connecting pipe 8; the top of the clamping block 2 is fixedly connected to a fixing rod 7; the top of the fixing rod 7 is fixedly connected to a limit block 5; the top of the fixing rod 7 is slidably connected to a disengagement block 6; during work, the staff can align the chuck 1 with the limit block 5 at the top of the clamping block 2 and insert the limit block 5 into the inside of the chuck 1. As the limit block 5 is inserted, the four internal springs 3 are squeezed by the limit block 5 and begin to contract, driving the four limit rods 4 to contract. Whenever the limit block 5 completely enters the inside of the chuck 1, the four internal springs 3 lose pressure and expand again, driving the four limit rods 4 to extend. After the chuck 1 is lifted up, the chuck 1 is lifted up and the chuck 1 is released.

[0026] like Figure 1 and Figure 3As shown, a hydraulic rod 10 is provided on the top of the connecting pipe 8; a movable block 11 is fixedly connected to the top of the hydraulic rod 10; the internal rotation of the movable block 11 is connected to the first pulley 12, and the two first pulleys 12 are symmetrically arranged; a support rod 13 is provided at the bottom of the first pulley 12, and multiple support rods 13 are arranged in parallel; support blocks 14 are fixedly connected to both ends of the support rod 13; when working, the staff can control the positions of multiple chucks 1 through the movable block 11, so that the chuck 1 moves on the support rod 13, thereby sending the block 2 at the bottom of the chuck 1 to the predetermined location, and the staff can control the rise and fall of the chuck 1 through the hydraulic rod 10. This then assists in the transportation of the card block 2, and realizes the fixation and separation of the chuck 1 and the card block 2. During the movement of the movable block 11 on the support rod 13, the symmetrically arranged first pulley 12 slides on the top of the support rod 13 and provides sufficient supporting force for the chuck 1 and the card block 2. With the help of the support blocks 14 at both ends of the support rod 13, the parallelism of multiple support rods 13 can be maintained, so that the movement of the support rod 13 is stable; this step realizes the movement of the chuck 1 and the card block 2 by setting the movable block 11, meets the equipment parts moving needs during the equipment installation process, improves the flexibility of the fixing device, and the equipment parts fixed to the bottom of the card block 2 can move freely, thereby making the equipment installation work more efficient.

[0027] like Figure 1 and Figure 2 As shown, the bottom of the support block 14 is rotatably connected to the second pulley 15, and the two second pulleys 15 are symmetrically arranged, and the multiple support blocks 14 are slidably connected to the connecting rod 23; the bottom of the two second pulleys 15 is provided with a support frame 16, and the two support frames 16 are arranged in parallel; the side wall of the support frame 16 is provided with a movable groove 22 corresponding to the position of the support rod 13; when working, the multiple support rods 13 move within the range of the movable groove 22 opened on the side walls of the two support frames 16, and whenever the support block 14 moves on the top of the support frame 16 When the second pulley 15 is symmetrically arranged, it rotates on the top of the support frame 16, reducing the friction between the structures. The two ends of the connecting rod 23 are fixed to the support frame 16, and the support block 14 is constrained by the two connecting rods 23 on the two support frames 16, further keeping the multiple support rods 13 parallel. This step makes the movement of the support block 14 more efficient by setting the second pulley 15, reduces the friction between the structures, helps to reduce the jamming between the structures, enhances the operating stability of the device, and is conducive to the efficient installation of the equipment.

[0028] like Figure 1 and Figure 2As shown, the bottom of the support frame 16 is fixed with a support column 17; a crossbeam 18 is fixed between the two support frames 16; the bottom of the support column 17 is rotatably connected to a third pulley 19, and the two third pulleys 19 are symmetrically arranged; during work, after the staff fixes the block 2 inside the chuck 1, the position of the block 2 can be changed by moving the position of the support rod 13, or the position of the block 2 can be moved by directly moving the entire device. With the help of the third pulley 19 at the bottom of multiple support columns 17 and the structure of the device, the staff can move the block 2 and the parts fixed to the bottom of the block 2 to the installation point; this step connects the two support frames 16 by setting the crossbeam 18, and realizes the overall movement of the device by setting the third pulley 19, which solves the problem of limited operating range of the fixing device and improves the flexibility and practicality of the device.

[0029] like Figure 3 As shown, a connecting piece 9 is fixed to the top of the connecting pipe 8; the top of the connecting piece 9 is fixed to the output end of the hydraulic rod 10; during operation, when inserting the block 2 into the chuck 1, the staff can use the connecting piece 9 to change the angle of the chuck 1, thereby making the connection between the chuck 1 and the block 2 more convenient; this step improves the structural flexibility of the device by setting the connecting piece 9, which is conducive to solving the problem of difficult connection between the chuck 1 and the block 2, making the device practical and convenient.

[0030] like Figure 2 As shown, the top of the support frame 16 is fixedly connected to a limit bar 21, and the two limit bars 21 are arranged corresponding to the second pulley 15; during operation, when the support block 14 moves at the top of the support frame 16, in addition to the inner side wall of the support frame 16 restricting the two ends of the support block 14, the limit bar 21 located at the bottom of the support block 14 also restricts the support block 14; this step improves the movement stability of the support block 14 by setting the limit bar 21 at the top of the support frame 16 to restrict the support block 14, which is beneficial to the smooth movement of the support rod 13.

[0031] like Figure 1 and Figure 2 As shown, a reinforcing plate 20 is fixed between the support columns 17, and the two reinforcing plates 20 are arranged in parallel; when working, the two reinforcing plates 20 connect the support columns 17 to make the force on the support columns 17 equal; this step balances the force on the support columns 17 by setting the reinforcing plates 20, which is conducive to solving the problem of uneven force during the movement of the device, enhancing the structural strength of the device, and helping to extend the service life of the device.

[0032] During operation, the staff can align the chuck 1 with the limit block 5 at the top of the block 2 and insert the limit block 5 into the inside of the chuck 1. As the limit block 5 is inserted, the four built-in springs 3 are squeezed by the limit block 5 and begin to shrink, driving the four limit rods 4 to shrink. Whenever the limit block 5 completely enters the inside of the chuck 1, the four built-in springs 3 lose pressure and expand again, driving the four limit rods 4 to extend. After the four limit rods 4 are extended, the bottom of the limit block 5 is restricted by the four limit rods 4, thereby achieving the fixation of the limit block 5. The staff can move the block 2 at the bottom of the chuck 1 by moving the chuck 1. When the block 2 reaches the predetermined position, the block 2 can be placed on the ground and the chuck 1 continues to move downward. During the process, the limit block 5 on the top of the fixing rod 7 enters the connecting rod. Inside the pipe 8, when the four limit rods 4 pass through the disengagement block 6, the chuck 1 is immediately moved upward. Since the top of the disengagement block 6 lacks support, the disengagement block 6 will move with the limit rod 4 until the disengagement block 6 reaches the bottom of the limit block 5. The four fours finally pass through the disengagement block 6 and the limit block 5 to achieve the separation of the chuck 1 and the block 2. The staff can control the positions of multiple chucks 1 through the movable block 11 to make the chuck 1 move on the support rod 13, so as to send the block 2 at the bottom of the chuck 1 to the predetermined location. The staff can control the rise and fall of the chuck 1 through the hydraulic rod 10, thereby assisting the transportation of the block 2 to achieve the fixation and separation of the chuck 1 and the block 2. During the movement of the movable block 11 on the support rod 13, the symmetrically arranged first pulley 12 moves on the support rod 1 3 top slides and provides sufficient supporting force for the chuck 1 and the block 2. With the help of the support blocks 14 at both ends of the support rod 13, the parallelism of the multiple support rods 13 can be maintained, so that the movement of the support rods 13 is stable. The multiple support rods 13 move within the range of the movable grooves 22 opened on the side walls of the two support frames 16. Whenever the support block 14 moves on the top of the support frame 16, the symmetrically arranged second pulley 15 rotates on the top of the support frame 16, reducing the friction between the structures. Among them, the two ends of the connecting rod 23 are fixed to the support frame 16, and the support block 14 is constrained by the two connecting rods 23 on the two support frames 16, further keeping the multiple support rods 13 parallel. After the staff fixes the block 2 inside the chuck 1, they can move the support rods 13 to change the position of the block 2, or by directly moving the entire device to move the position of the block 2, with the help of the third pulley 19 at the bottom of multiple support columns 17 and the structure of the device, the staff can move the block 2 and the parts fixed to the bottom of the block 2 to the installation point. In the process of inserting the block 2 into the chuck 1, the staff can use the connecting piece 9 to change the angle of the chuck 1, thereby making the connection between the chuck 1 and the block 2 more convenient. In the process of the support block 14 moving at the top of the support frame 16, in addition to the inner side wall of the support frame 16 restricting the two ends of the support block 14, the limit bar 21 at the bottom of the support block 14 also restricts the support block 14, and the two reinforcing plates 20 connect the support columns 17 to make the force on the support columns 17 equal.
