Abstract
The utility model discloses a safety tamping-proof clip on polished rod which contains a work sleeve fitted over the polished rod, suspension rings are arranged on the outside wall of the work sleeve symmetrically, the inner wall of the work sleeve is downward cone surface, two symmetric tooth blocks are arranged along the polished rod in the work sleeve, the external wall of the tooth blocks match with the inner wall, non-skid threads are arranged on the inner wall of the tooth blocks, ring horizontal grooves in which spring rings are installed are arranged on the external wall of the tooth block, a gland with a central hole is installed on the top surface of the work sleeve through a bolt, the size of the central hole matched with the external diameter of the polished rod, a pressure spring is fitted over the polished rod between the bottom of the gland and the top of both tooth blocks. The utility model not only has a simple structure preventing sand, dust, rain and snow from entering into the clip of the polished rod, but also has convenient operation on pump meeting to prevent personal injury and fatal accidents, such as fingers being smashed by the clip of the polished rod, and ensure safe and reliable operation.
Description
Technical field
The utility model belongs to the improvement of the polish rod clamp minor structure that is installed on the oil-extractor polish-rod, particularly the anti-polished rod clamp of pounding of safety.
Background technology
The oil-extractor polish-rod clamp not only plays a part fixedly connected polished rod and polished rod eye in the rod-pumped well ordinary production, and influenced by sand, wax etc. and when causing fault such as pump leakage at the oil well deep well pump, bump the pump operation for operating personnel and recover the deep well pump operate as normal and also play an important role.But used oil-extractor polish-rod clamp bumps pump operated difficulty at present, clamp often takes place in the operating process injure human casualty accidents such as finger by a crashing object.
Summary of the invention
The purpose of this utility model is to provide a kind of safety the anti-polished rod clamp of pounding, not only simple in structure, can prevent that sand, dust, sleet etc. from entering in the polished rod clamp, and bump pump operated convenience, can prevent the polished rod clamp effectively and injure human casualty accidents such as finger by a crashing object, safe and reliable.
The purpose of this utility model is achieved in that the anti-polished rod clamp of pounding of a kind of safety, comprise the work sleeve that is sleeved on the polished rod, be symmetrical arranged suspension ring on the periphery wall of work sleeve, the internal perisporium of work sleeve is the back taper face, in the work sleeve, two block teeth that are centrosymmetric along polished rod are being set, the periphery wall shape of block teeth is complementary with the internal perisporium shape of work sleeve, anti-skidding line is being set on the internal perisporium of block teeth, annular horizontal groove all is being set on the periphery wall of two block teeth, suit turn in the annular horizontal groove, on the end face of work sleeve, the gland with central through hole is installed by bolt, the size of this central through hole and the external diameter of polished rod are complementary, and suit compression spring on the polished rod between gland bottom surface and the two block teeth end faces.
After gland of the present utility model installed, just can compress block teeth downwards, and under the effect of turn, hold polished rod then tightly by the compression spring that is sleeved on the polished rod.In addition, owing to by bolt the gland with central through hole is installed on the end face of work sleeve, the size of this central through hole and the external diameter of polished rod are complementary, and can prevent that like this sand, dust, sleet etc. from entering in the polished rod clamp; Be symmetrical arranged suspension ring on the periphery wall of work sleeve, operating personnel can hold on to a strap with hand and bump pump operatedly then, bump pump operated convenience, can prevent the polished rod clamp effectively and injure human casualty accidents such as finger by a crashing object, and are safe and reliable.The utility model is simple in structure, is easy to make, and be the ideal substitute of the used polished rod clamp of present oil pumper.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks cross-sectional view for master of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of looking up of the present utility model.
In the accompanying drawing: the 1-suspension ring; The 2-sleeve of working; The 4-compression spring; The 5-polished rod; The 6-gland; The 7-block teeth; The 8-turn.
The specific embodiment
A kind of safety is anti-pounds the polished rod clamp, as Fig. 1, Fig. 2, shown in Figure 3, comprises the work sleeve 2 that is sleeved on the polished rod 5, and the bottom of work sleeve 2 has an annular lip.Be symmetrical arranged suspension ring 1 on the periphery wall of work sleeve 2, the internal perisporium of work sleeve 2 is the back taper face, in work sleeve 2, two block teeth 7 that are centrosymmetric along polished rod 5 are being set, the periphery wall shape of block teeth 7 is complementary with the internal perisporium shape of work sleeve 2, anti-skidding line is being set on the internal perisporium of block teeth 7, is helping to hold tightly polished rod 5.Annular horizontal groove all is being set on the periphery wall of two block teeth 7, and suit turn 8 in the annular horizontal groove, can prevent that under the effect of turn 8 the 7 upper and lower actions of two block teeth are asynchronous, helps block teeth 7 to hold polished rod 5 tightly simultaneously.By bolt the gland 6 with central through hole is installed on the end face of work sleeve 2, the external diameter of the size of this central through hole and polished rod 5 is complementary, and can prevent that like this sand, dust, sleet etc. from entering in the polished rod clamp.Suit compression spring 4 on the polished rod 5 between gland 6 bottom surfaces and two block teeth, 7 end faces, can compress block teeth 7 downwards.The cross section of two block teeth 7 is a watt shape.Gland 6 is two halves, and the contact two ends of side of two halves gland 6 have lug respectively and are hinged together, can make things convenient for the dismounting of gland.
