Description

Technical Field

[0001] The utility model relates to auxiliary equipment for processing plastic extruded pipes, more specifically, to a movable bracket device for plastic extruded pipes. Background Art

[0002] When producing plastic extrusion pipes, a bracket is needed to suspend the extruded pipe to a high position at the same center as the extrusion equipment. This is to ensure that the extruded pipe is straight. Pipes of different specifications have different outer diameters, so the bracket should be able to adjust the height so that the extruded pipe can be at the same center height as the extrusion equipment. The bracket is generally Y-shaped, with rollers on both sides to reduce friction resistance during the movement of the pipe and reduce traction during the production process.

[0003] The existing bracket adopts screw-type lifting, and the height is raised and lowered by rotating the nut. Although this method is simple, it is not stable to operate, the lifting speed is slow, it is laborious, and the operating space is large. At the same time, the conventional bracket rollers are simple and do not use bearings or use ordinary bearings, which cannot withstand the deadweight load and the axial load of traction, and have a short service life. During production, the rollers are prone to get stuck, causing the bracket to tip over, affecting production and product quality. Utility Model Content

[0034] It should be noted that the fixing plate 206 is connected to the outer square tube sleeve 205 by welding.

[0035] like Figure 4 and Figure 5 As shown, the lifting assembly 3 includes a hand crank component 301 and a lifting component 302 , and the hand crank component 301 includes a hand crank handle 30101 , a ratchet 30105 , a pawl 30106 and a hand crank driving wheel 30110 .

[0036] like Figures 6 to 9 As shown, the lifting assembly 302 includes a lifting gear 30201, a transmission wheel 30202 and a rack 30203. A rack hole 302031 is defined at the bottom of the rack 30203.

[0037] The hand-cranked driving wheel 30110 is meshed with the transmission wheel 30202 , the transmission wheel 30202 is meshed with the lifting gear 30201 , and the lifting gear 30201 is meshed with the rack 30203 .

[0038] Specifically, the lifting gear 30201 has two cylindrical ends, with two gears positioned in the middle. The left pinion meshes with the rack 30203, while the right large gear meshes with the small gear of the transmission wheel 30202. The transmission wheel 30202 also has two cylindrical ends, with two gears positioned in the middle. The left large gear meshes with the gear of the hand-cranked driving wheel 30110, while the right small gear meshes with the right large gear of the lifting gear 30201.

[0041] The method for using the mobile support device for plastic extrusion pipes is as follows, comprising the following steps:

[0042] Step S1, installing the roller assembly 1;

[0043] Step S2, installing the hand crank assembly 301;

[0044] Step S3, installing the lifting assembly 302;

[0045] Step S4: Assemble the hand crank assembly 301 onto the lifting assembly 302 and fix them with bolts to form the lifting assembly 3;
