An electric adjustment module two for controlling the lifting of the mounting frame 106 is further provided between the base 101 and the sliding frame 103.

[0022] As Figure 2 , 3 , as shown in Figures 4, the electric adjustment module one includes two symmetrically distributed front and rear slide rails 301 provided inside the upper end of the sliding frame 103. A sliding seat 302 is slidably provided between the two slide rails 301. Two symmetrically distributed front and rear adjustment rods 303 are rotatably provided at the upper end of the sliding seat 302. The ends of the two adjustment rods 303 away from the sliding seat 302 are rotatably connected to the mounting frame 106 respectively. An electric drive unit for driving the sliding seat 302 to move is further provided on the sliding frame 103. The electric drive unit includes an adjustment screw rod two 304 rotatably provided inside the upper end of the sliding frame 103. The adjustment screw rod two 304 is threadedly connected to the sliding seat 302. A drive motor 305 is provided on the left side of the sliding frame 103. The output shaft of the drive motor 305 is fixedly connected to the adjustment screw rod two 304 through a coupling.

[0023] As Figure 2 , 3As shown in FIGS. 3 and 4, the second electric adjustment module includes two guide rails 201 symmetrically distributed front and back at the lower end inside the base 101. Two adjustment seats 202 symmetrically distributed left and right are slidably arranged between the two guide rails 201. Four uniformly distributed support seats 203 are welded and fixed to the upper side inside the sliding frame 103. Guide rails 204 are arranged between two adjacent support seats 203 on the left and right. Two adjustment seats 205 symmetrically distributed left and right are slidably arranged between the two guide rails 204. Two connecting rods 206 symmetrically distributed front and back are rotatably arranged at the upper end of the left adjustment seat 202. Two connecting rods 207 symmetrically distributed front and back are rotatably arranged at the upper end of the right adjustment seat 202. The ends of the connecting rods 206 and 207 far from the adjustment seat 202 are respectively rotatably connected to the adjacent adjustment seats 205. The middle parts of the connecting rods 206 and 207 are rotatably connected. An electric control unit for driving the movement of the adjustment seat 202 is further arranged inside the base 101; the electric control unit includes two support seats 208 symmetrically distributed left and right welded and fixed to the lower end inside the base 101. One end of each adjustment screw rod 209 far from the vertical center of the base 101 is rotatably arranged between the support seat 208 and the inner wall of the base 101. The adjustment screw rods 209 are respectively threadedly connected to the adjacent adjustment seats 202. A double-shaft motor 210 is arranged in the middle of the lower end inside the base 101. The output shafts of the double-shaft motor 210 are respectively fixed to the adjacent adjustment screw rods 209 through couplings.

[0024] As shown in Figure 1 and 2 FIGS. 3 and 4, a control switch 401 is arranged on the front side of the sliding frame 103. The double-shaft motor 210 and the drive motor 305 are both electrically connected to the control switch 401.

[0025] During the use process, the catwalk machine is installed and fixed between two mounting plates 107 on the mounting frame 106 by screwing bolts passing through the mounting holes 108 with external tools.

[0026] When it is necessary to adjust the height of the catwalk machine, the dual-axis motor 210 is controlled to operate through the control switch 401, so that the dual-axis motor 210 drives the adjusting lead screw 209 connected to it to rotate respectively. Driven by the threaded relationship between the adjusting lead screw 209 and the first adjusting seat 202, the left and right first adjusting seats 202 slide between the two first guide rails 201. During the movement of the two first adjusting seats 202, rotation occurs between the left first adjusting seat 202 and the first connecting rod 206, rotation occurs between the right first adjusting seat 202 and the second connecting rod 207, and rotation occurs between the second connecting rod 207 and the first connecting rod 206, driving rotation between both the first connecting rod 206 and the second connecting rod 207 and the second adjusting seat 205, so that the two first adjusting seats 202 drive the two second adjusting seats 205 to slide between the two second guide rails 204 through the first connecting rod 206 and the second connecting rod 207. Since the lengths of the first connecting rod 206 and the second connecting rod 207 are fixed, the two second adjusting seats 205 drive the sliding frame 103 to slide relative to the base 101, causing the sliding frame 103 to drive the catwalk machine to rise or fall, and enabling the height of the catwalk machine to be adjusted quickly and stably.

[0027] When it is necessary to adjust the installation angle of the catwalk machine, the driving motor 305 is controlled to operate through the control switch 401, so that the output shaft of the driving motor 305 drives the adjusting lead screw 304 connected to it to rotate. Then, driven by the threaded relationship between the adjusting lead screw 304 and the sliding seat 302, the sliding seat 302 slides between the two slide rails 301. During the movement of the sliding seat 302, rotation occurs between the sliding seat 302 and the adjusting rod 303, and rotation occurs between the adjusting rod 303 and the mounting bracket 106, so that the sliding seat 302 drives the mounting bracket 106 to rotate relative to the right U-shaped seat 104 through the adjusting rod 303, enabling the mounting bracket 106 to drive the angle of the catwalk machine to be adjusted quickly.

[0028] According to another embodiment of the present invention, as Figure 1 , 2 , as shown in Figure 4, four evenly distributed spring telescopic columns 109 are provided at the lower end inside the base 101, and the telescopic ends of the spring telescopic columns 109 are fixedly connected to the sliding frame 103 through bolts. During the daily support or adjustment of the catwalk machine, the sliding frame 103 can be effectively buffered by the four evenly distributed spring telescopic columns 109, which can effectively assist in the adjustment and support of the catwalk machine.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, shall be covered within the scope of the claims of the present invention.
