The right end of the first threaded rod 7 is fixedly connected to the second threaded rod 8. The first threaded rod 7 and the second threaded rod 8 are connected to each other. The outer surface of each of the driving blocks 9 is connected with a driving block 9 through a threaded sleeve, and a second cylinder 11 is arranged inside the other end of the driving block 9. The second cylinder 11 has the function of driving the clamping block 13 to move up and down to adjust the height. A second cylinder rod 12 is arranged on the upper end of the second cylinder 11, and a clamping block 13 is fixedly connected to the upper end of the second cylinder rod 12. Through the arrangement of four clamping blocks 13, the four corners of the electric hoist 14 are clamped to fix the electric hoist 14, so that when the electric hoist 14 lifts a heavy object with one side heavier and the other side lighter, the electric hoist 14 will not tilt or lift up. There are four clamping blocks 13, and the electric hoist 14 is clamped and fixed between the four clamping blocks 13. The electric hoist 14 has the function of lifting heavy objects.

[0026] See also Figure 2 and Figure 3There are two first cylinders 3, support frames 5, motors 6, first threaded rods 7, second threaded rods 8, etc., and four second cylinders 11 and clamping blocks 13. Through the arrangement of the two first cylinders 3, motors 6, etc. and the arrangement of the four second cylinders 11, etc., the four clamping blocks 13 can be driven to move left and right, front and back, up and down to adjust their positions, thereby clamping and fixing electric hoists 14 of different sizes. The threads of the first threaded rod 7 and the second threaded rod 8 are arranged oppositely, and the thread of the first threaded rod 7 is arranged as a positive thread, and the thread of the second threaded rod 8 is arranged as a reverse thread. Through the arrangement of the first threaded rod 7 and the second threaded rod 8 with opposite threads, the driving block 9 and the clamping block 13 can be driven to move toward or oppositely at the same time.

[0027] See also Figure 2 and Figure 5 The second threaded rod 8 is rotatably connected to the inner right end of the support frame 5. The support frame 5 has the function of supporting and balancing the right end of the second threaded rod 8, and in the process of supporting and balancing, it does not hinder the rotation of the second threaded rod 8. A ball 10 is arranged inside one end of the driving block 9, and the ball 10 is slidably connected to the support frame 5. The ball 10 has the function of reducing the contact area and friction between the driving block 9 and the support frame 5, thereby increasing the smoothness of the movement of the driving block 9 in the support frame 5.

[0028] When the electric hoist installation structure of the electric hoist bridge crane is in use, the electric hoist 14 is placed in the middle part of the installation driving plate 2, and then the lifting hook and chain of the electric hoist 14 are respectively passed through the circular groove provided on the installation driving plate 2. At this time, the first cylinder 3 at the front and rear ends is opened first, and the first cylinder 3 drives the clamping block 13 to approach the position of the electric hoist 14 through the first cylinder rod 4 and the support frame 5. After the lateral position of the clamping block 13 is aligned with the position of the four corners of the electric hoist 14, the clockwise switch of the motor 6 is turned on, and the motor 6 drives the first threaded rod 7 and the second threaded rod 8 to rotate clockwise. Due to the setting of the first threaded rod 7 and the second threaded rod 8 with opposite threads, and the threaded connection of the driving block 9, the motor 6 can drive the driving block 9 and the clamping block 13 to move toward each other through the first threaded rod 7 and the second threaded rod 8. At this time, the vertical position of the clamping block 13 is aligned with the vertical position of the clamping block 13. The four corners of the electric hoist 14 are aligned, and then the second cylinder 11 is turned on. The second cylinder 11 drives the clamping block 13 to move downward through the second cylinder rod 12, so that the clamping block 13 moves to be close to the upper surface of the electric hoist 14. At this time, the clamping block 13 can clamp and fix the four corners of the electric hoist 14 and the main body of the electric hoist 14. The operation is simple and the fixation is relatively stable. When the electric hoist 14 is lifting heavy objects, the electric hoist 14 will not tilt or move. It has the function of ensuring that the electric hoist 14 is firmly fixed on the mounting driving plate 2 to work. Since the front and rear positions, up and down positions, and left and right positions of the clamping block 13 can be adjusted, different models of electric hoists 14 can be fixed and used, and the scope of application is wide. Because the fixing method is simple, it is also convenient to disassemble the damaged electric hoist 14 for repair, which is conducive to use.
