Problems solved by technology

[0003] At present, most of the vibrating screens used in oilfield drilling and workover use hook-side screens. The hook-side screens are usually fixed with 4 screws on both sides of the vibrating screen, and then the vibrating screen is tightened by the pressure plate. The tensioning of the screen, however, takes about 30 minutes to fix a screen with bolts, which undoubtedly increases the labor intensity of the workers, wastes labor, seriously reduces the production efficiency of the vibrating screen, and is difficult to meet the vibration A market with high demand for sieve mesh
In addition, this method of tensioning the vibrating screen makes the deformation of the pressing plate and the hook edge of the vibrating screen large and the force on the vibrating screen is uneven, thereby reducing the service life of the vibrating screen

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0016] Such as figure 1 , figure 2 , Figure 4 As shown, a quick tensioning device for a vibrating screen includes a tensioning bolt 1, an end face cam 2, a stress sleeve 3, a rotating head 4, a steel wire retaining ring 16, a flat washer 15, an adjusting nut 12 and a lock nut 13. The front end of the tensioning bolt 1 passes through the end cam 2, the bearing sleeve 3 and the flat washer 15 in turn. The end cam 2 has a hexagonal guide hole 6 in the center, and one end of the bearing sleeve 3 is an outer hexagonal column 10. The outer hexagonal column 10 is placed in the guide hole 6, the force sleeve 3 is set on the tension bolt 1 and the other end of the force sleeve 3 is assembled in the inner hole of the rotation head 4, and the end of the force sleeve 3 Ring-shaped ribs 17 are provided, and ...

Abstract

The invention discloses a rapid tensioning device of screen cloth of a vibrating screen. The rapid tensioning device comprises a tensioning bolt (1), an end face cam (2), a stress sleeve (3), a rotary head (4), a flat washer (15), an adjusting nut (12) and a locking nut (13). The rotary head (4) is rotated to adjust the axial position of the tensioning bolt (1), so that the screen cloth (20) is tensioned and released. The rapid tensioning device has the advantages of being compact in structure and high in tensioning efficiency of the screen cloth of the vibrating screen, and reducing labor amount of workers.

Description

technical field [0001] The invention relates to the technical field of tensioning screens of vibrating screens for oil drilling, in particular to a quick tensioning device for screens of vibrating screens. Background technique [0002] At present, the scope of application of the vibrating screen is very wide. The vibrating screen is mainly used in petroleum, coal, smelting, building materials, refractory materials, chemical industry and other industries, especially in the oil drilling industry. The vibrating screen is mainly used to remove cuttings and other harmful solid particles in the drilling fluid. On the one hand, the vibrating screen is required to have a large processing capacity and can remove as many solid particles in the drilling fluid as possible; On the other hand, the continuous update and development of the vibrating screen mesh is required. A large number of experiments have proved that the vibrating sieve screen has better performance in dealing with cutt...
