Abstract
A belt tip connecting device comprises a belt 1, a shell 2, a taper seat 3, taper pressing plates 4, a cylindrical pin 5, a connecting rod 6 and a beam hanger 7. The taper seat 3 is welded in the shell 2 to form an internal space with a wide top and a narrow bottom, and the taper pressing plates 4 are arranged on two sides of the belt 1 and are fitted together with the belt to form a solid body with a narrow top and a wide bottom. A through hole is drilled on the lower portion of the shell 2, the shell 2 is connected with the upper portion of the connecting rod 6 through the cylindrical pin 5, and the lower portion of the connecting rod 6 is connected with the beam hanger. A groove is firstly machined on a steel plate of the shell 2, a machined tapered steel plate is placed into the groove, and the upper end face and the lower end face of the tapered steel plate are welded, so that the tapered steel plate is integrated with the shell. Each taper pressing plate is provided with a thick end and a thin end, a plurality of mutually equal saw teeth are machined on one surface of each taper pressing plate contacting with the belt, the other surface of each taper pressing plate contacting with the taper seat of the shell is machined into a polished surface, the belt extends into the shell from the top of the shell and is pulled out from the bottom of the shell, two sides of the belt are clamped by the taper pressing plates respectively, and the belt and the taper pressing plates are plugged into the shell together and can be tensioned.
Description
Technical field
The utility model relates to petroleum equipment, relates in particular to a kind of tower-type belt oil pumping machine.
Background technique
In recent years, fast development along with modern science and technology, the technological innovation of petroleum equipment also is with rapid changepl. never-ending changes and improvements, particularly account for the pumping unit of petroleum equipment cost 40%, new product emerges in an endless stream especially, wherein there is a composite permanent magnetism synchronous machine pumping unit also to appear on the oil-field oil pumper market, its belt end connecting device structure such as Fig. 1, this kind structure compresses the belt principle and utilizes some screw in compression belts, use and principle analysis by reality, obviously design owes rationally easily to the belt injury, to have a strong impact on load carrying capacity and the working life of belt.Simultaneously, to the compression of belt fully be with manual with spanner to bolt tightening, labor intensity is large, inefficiency, poor reliability, belt is slippage sometimes.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of simple in structure, the belt end connecting device of reliable performance.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of belt end connecting device is by belt 1, housing 2, conical seat 3, conical pressure plate 4, straight pin 5, connecting rod 6, rope hanger 7 consists of, the conical seat 3 of burn-oning in housing 2 forms up-narrow and down-wide inner space, and the both sides of belt 1 are conical pressure plates 4, and the three fits together and forms up-narrow and down-wide entity.Bore through hole in the bottom of housing 2, with straight pin 5 housing 2, connecting rod 6 tops are connected, the bottom of connecting rod 6 is connected with rope hanger 7.
The beneficial effects of the utility model are: adopt the belt lacings connection set, its working principle is to utilize inclined plane principle, when belt and both sides conical pressure plate can draw tighter and tighter under the load effect, belt itself is neither holed, compress without the screw top again and roll, be unlikely the structural damage that causes the damage of belt surface and belt, therefore, this apparatus structure is simple, principle is advanced, easy to operate, compress reliably, greatly prolong the life-span of belt.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but protection domain of the present utility model is not limited to following embodiment.
The belt end connecting device that the utility model provides comprises belt 1, housing 2, and conical seat 3, conical pressure plate 4, straight pin 5, connecting rod 6, rope hanger 7 consists of.Described housing 2 is Bao or mill and process first groove on hull plate, the pre-processed steel plate with tapering is put into groove, and in the upper and lower end face welding, itself and housing 2 are become one; Described conical pressure plate 4 is to utilize Bao or the method for milling is processed the thin conical pressure plate of the thick end of an end, some the sawtooth parallel to each other of one side processing that contact with belt, the one side that contacts with the housing conical seat is processed into the light face, during installation, the top of belt 1 from housing 2 put in and pull out from bottom, each presss from both sides tapering pressing plate 4 on the belt both sides again, notice that tapering pressing plate 4 is up-narrow and down-wide, then they are filled in housing 2 together, tightening belt 1, just draw tighter and tighter, between housing 2 and rope hanger 7, load onto at last connecting rod 6 and straight pin 5.
