In addition, the three-dimensional spatial dimensions including length, width and depth should be included in actual production.

[0026] Referring to Figs. 1-3 For one embodiment of the present application, a petroleum chemical pipeline maintenance workbench is provided, comprising a main unit 100, an adjusting unit 200 and a positioning unit 300.

[0027] Among them, the main unit 100 includes a workbench main body 101 and a support leg 102 matched and installed with the workbench main body 101, the support leg 102 is located at the bottom of the four corners of the workbench main body 101, and the support leg 102 is used to ensure the stability of the workbench main body 101;

[0028] The positioning unit 300 comprises mounting frames 301 symmetrically mounted at the top end of the workbench body 101, V-shaped plates 302 symmetrically mounted at the bottom end of the inner cavities of the two groups of mounting frames 301, V-shaped seats 303 slidingly connected to the top end of the two groups of mounting frames 301 and located between the two groups of V-shaped plates 302, mounting plates 307 mounted at the two sides of the two groups of mounting frames 301, movable grooves 308 formed in the side of the mounting plates 307 close to the mounting frames 301 and rotatingly connected with screw rods 309 in the inner cavities of the movable grooves 308, movable blocks 310 threadedly connected to the outer surfaces of the screw rods 309, the movable blocks 310 slidingly connected with the movable grooves 308 and fixedly connected with the side walls of the V-shaped seats 303 at one side, and transmission structures arranged at the top end of the mounting frames 301. The two ends of the pipeline to be repaired are placed in the V-shaped grooves of the V-shaped plates 302, then the transmission mechanism is utilized to rotate the screw rods 309. Since the screw rods 309 and the movable blocks 310 are threadedly connected and the movable grooves 308 play a key limiting role in the movement of the movable blocks 310, the movable blocks 310 can be guided to move downward, and with the movement of the movable blocks 310, the V-shaped seats 303 are further driven to move downward, so that the pipeline is stably clamped and positioned. This not only significantly reduces the labor cost, but also effectively improves the efficiency of the repair work.

[0029] The transmission structure comprises first sprockets 304 rotatingly connected to the top end of the two groups of mounting frames 301, second sprockets 305 fixedly mounted at the top end of the four groups of screw rods 309 and provided with transmission chains 306 on the outer surfaces of the first sprockets 304 and the second sprockets 305. When the first sprockets 304 are rotated, they drive the transmission chains 306 to rotate, and the transmission chains 306 in turn drive the second sprockets 305 to rotate at the same direction and speed, and then the rotation of the second sprockets 305 further drives the screw rods 309 to rotate.

[0030] The top end of the two groups of first sprockets 304 is provided with a turntable 311, and the outer surface of the turntable 311 is provided with a non-slip sleeve. The turntable 311 drives the first sprockets 304 to rotate.

[0031] The adjusting unit 200 comprises a sliding groove 202 formed in the top end of the workbench body 101, the inner cavity of the sliding groove 202 is rotationally connected with a bidirectional screw rod 203, the two ends of the bidirectional screw rod 203 are threadedly connected with sliding blocks 204, and the top ends of the two groups of sliding blocks 204 are fixedly connected with the bottom ends of the two groups of mounting frames 301, one side of the workbench body 101 is fixedly installed with a motor 201, and the output end of the motor 201 is fixedly connected with one end of the bidirectional screw rod 203, after the motor 201 is started, the motor 201 drives the bidirectional screw rod 203 to start rotating, since the two ends of the bidirectional screw rod 203 are designed with opposite threads, therefore, when the bidirectional screw rod 203 rotates, the sliding blocks 204 located at the left and right ends thereof will move synchronously towards or away from each other under the limiting guidance of the sliding groove 202, so that the mounting frames 301 can be driven to adjust the position, thereby conveniently clamping the pipeline to be maintained with different lengths.

[0032] The top end of the workbench body 101 is symmetrically formed with limiting grooves 205, the two sides of the two groups of limiting grooves 205 are slidably connected with limiting blocks, and the top end of the limiting block is fixedly connected with the bottom end of the mounting plate 307, when the mounting frame 301 moves, the mounting plate 307 is driven to move, and then the limiting block is driven to slide in the limiting groove 205, so as to ensure the stability of the mounting frame 301 during movement.

[0033] The opposite surfaces of the V-shaped plate 302 and the V-shaped seat 303 are provided with anti-skid pads, and the V-shaped grooves of the V-shaped plate 302 and the V-shaped seat 303 are opposite, so as to prevent the pipeline from sliding or falling off during clamping, and ensure the stability of clamping.

[0034] During use, after the motor 201 is started, the motor 201 drives the bidirectional screw rod 203 to start rotating, since the two ends of the bidirectional screw rod 203 are designed with opposite threads, therefore, when the bidirectional screw rod 203 rotates, the sliding blocks 204 located at the left and right ends thereof will move synchronously towards or away from each other under the limiting guidance of the sliding groove 202, so that the mounting frames 301 can be driven to adjust the position, thereby conveniently clamping the pipeline to be maintained with different lengths, the two ends of the pipeline to be maintained are placed in the V-shaped grooves of the V-shaped plate 302, then the threaded rod 309 is driven to start rotating by using the transmission mechanism, since the threaded rod 309 and the movable block 310 are connected in a threaded manner, and the movable groove 308 plays a key limiting role during the movement of the movable block 310, which enables the movable block 310 to move downward under the guidance of the movable groove 308, with the movement of the movable block 310, it further drives the V-shaped seat 303 to move downward, so as to realize stable clamping and positioning of the pipeline, which not only significantly reduces the labor cost, but also effectively improves the efficiency of maintenance work.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
