Abstract
A belt end self-tightening device is formed by a belt 1, a shell 2, a taper seat 3, conical 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 inner space with a wide upper portion and a narrow lower portion. The conical pressing plates 4 are arranged on the two sides of the belt 1, and a solid body with a narrow upper portion and a wide lower portion is formed in a manner that the belt 1 is attached to the conical pressing plates 4. A through hole is drilled in the lower portion of the shell 2, the cylindrical pin 5 is used for connecting the shell 2 and the upper portion of the connecting rod 6, and the lower portion of the connecting rod 6 is connected with the beam hanger. According to the shell 2, a groove is firstly machined in a shell steel plate, a machined steel plate with certain conicity is placed in the groove, and welding is carried out on the upper end face and the lower end face of the machined steel plate, so that the machined steel plate and the shell can be made into a whole. Each conical pressing plate is machined into a shape with a thick end and a thin end, a plurality of parallel sawteeth are machined on the surface, making contact with the belt, of each conical pressing plate, and the surface, making contact with the taper seat of the shell, of each conical pressing plate is machined into a smooth surface. The belt extends into the shell from the top of the shell and is pulled out from the lower side of the shell, the conical pressing plates are clamped on the two sides of the belt, then the belt and the conical pressing plates are stuffed into the shell, and finally the belt is pulled tightly.
Description
Technical field
The present invention relates to petroleum equipment, relate 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 is also 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 oil-field oil pumper market, its belt termination hold down gag structure is as Fig. 1, this kind of structure compresses belt principle and utilizes some screw in compression belts, by reality, use and principle analysis, obviously design owes rationally, easily belt to be caused to damage, has a strong impact on load carrying capacity and the working life of belt.Meanwhile, belt is compressed to the pretightening force that relies on screw completely, poor reliability, labor intensity is large, inefficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of simple in structure, the belt termination Self tightening device of reliable performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of belt termination Self tightening device is by belt 1, housing 2, conical seat 3, conical pressure plate 4, straight pin 5, connecting rod 6, rope hanger 7 forms, 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 three fits together and forms up-narrow and down-wide entity.In the bottom of housing 2, bore through hole, 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 invention has the beneficial effects as follows: adopt belt termination Self tightening device, its working principle is to utilize inclined plane principle, when belt and both sides conical pressure plate can draw tighter and tighter under load effect, belt itself is neither holed, without screw top, compress and roll again, be unlikely the structural damage that causes belt surface damage and belt, therefore, this apparatus structure is simple, principle is advanced, easy to operate, compress reliably, greatly extend the life-span of belt.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, but protection scope of the present invention is not limited to following embodiment.
Belt provided by the invention termination Self tightening device, comprises belt 1, housing 2, and conical seat 3, conical pressure plate 4, straight pin 5, connecting rod 6, rope hanger 7 forms.Described housing 2 is that Bao or milling first process groove in hull plate, the pre-processed steel plate with tapering is put into groove, and in upper and lower end face welding, itself and housing 2 are become one; Described conical pressure plate 4 is the thin conical pressure plates in method processing thick one end, one end that utilize Bao or milling, and some sawtooth parallel to each other of the one side contacting with belt processing, to increase the pressure of pressing plate and belt.The one side contacting with housing conical seat is processed into light face, during installation, belt 1 is put in from the top of housing 2 and from pulling out below, on belt both sides, each presss from both sides tapering pressing plate 4 again, notice that tapering pressing plate 4 is up-narrow and down-wide, then they are filled in to housing 2 together, tightening belt 1, just draw tighter and tighter, finally between housing 2 and rope hanger 7, load onto connecting rod 6 and straight pin 5.
