The utility model provides the security of high workman when the well head is operated.
Description
Technical field
The utility model belongs to the technical field of well head safe operation tool, relates to a kind of well head safe folder.
Background technology
Oil pumper is a kind of heavy duty main equipment, do not have suitable operation tool when oil pumping machine well head operation is climbed and held up, and just formulates severe to forbid that hand grabs the systems such as polished rod.And maintenance personal is when well head carries out maintenance operation, often because a variety of causes can not be noted, there are some personal injury accidents, particularly the accident of polished rod tong, pinch occurs repeatedly, once there is accident, great misery will be caused to party, therefore, for solving the problem that oil pumping machine well head operation is inconvenient, security is low, it is necessary for proposing a kind of well head safe folder.
Summary of the invention
The technical problems to be solved in the utility model proposes a kind of well head safe folder, when effectively can solve well head operation, hand does not have place to climb to hold up, there is the problem of light rod-broken phenomenon hand clamping, pin, also can solve well head simultaneously and change the problems such as quick-clamping in the operating process such as packing is fixing.
The utility model solves the technical scheme that its technical problem adopts: a kind of well head safe folder, comprise movable teeth, fixing tooth, activity clamp handle, fixing clamp handle, support bar and adjusting screw(rod), described movable teeth is connected with the head of described activity clamp handle, and be hinged by bearing pin and described fixing clamp handle, described fixing tooth is connected with the head of fixing clamp handle, one end and the activity clamp handle of described support bar are hinged, in the chute that the other end of support bar stretches into fixing clamp handle and along slide, the afterbody bolt of described adjusting screw(rod) and fixing clamp handle, and abut against with the other end of support bar, it is characterized in that: the inner side of described movable teeth and fixing tooth is equipped with bearing tube, the corresponding setting of open side of described bearing tube.
By technique scheme, described bearing tube is semicolumn sleeve.
By technique scheme, the afterbody of described adjusting screw(rod) and fixing clamp handle is provided with inner thread sleeve bolt.
The beneficial effects of the utility model are: propose a kind of well head safe folder, by bearing tube and multi-grade lever are combined, effectively can solve well head operator and not have place to climb to hold up, occur the problem of light rod-broken phenomenon hand clamping, pin, also can realize quick-clamping simultaneously, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model.
Wherein: movable teeth 1, fixing tooth 2, activity clamp handle 3, fixing clamp handle 4, support bar 5, adjusting screw(rod) 6, chute 7, bearing tube 8, inner thread sleeve 9.
Detailed description of the invention
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of well head safe folder, comprise movable teeth 1, fixing tooth 2, activity clamp handle 3, fixing clamp handle 4, support bar 5 and adjusting screw(rod) 6, movable teeth is connected with the head of activity clamp handle, and be hinged by bearing pin and fixing clamp handle, fixing tooth is connected with the head of fixing clamp handle, one end and the activity clamp handle of support bar are hinged, in the chute 7 that the other end stretches into fixing clamp handle and along slide, the afterbody bolt of adjusting screw(rod) and fixing clamp handle, and abut against with the other end of support bar, the inner side of movable teeth and fixing tooth is equipped with bearing tube, the corresponding setting of open side of bearing tube, when applying the power near fixing clamp handle to activity clamp handle, the connecting portion of support bar and activity clamp handle will become a fulcrum, activity clamp handle just becomes a lever, the head of activity clamp handle can form an outside power, will drive movable teeth by with the interface point of fixing clamp handle centered by rotate, form second lever, movable teeth is made to obtain a larger strength and fixing tooth closes.
Bearing tube is semicolumn sleeve, and two bearing tubes are welded in fixing tooth and movable teeth respectively, and bearing tube internal diameter matches with the polished rod of oil pumper, under the multi-grade lever effect of safety clamp, can produce larger power, be engaged polished rod.The afterbody of adjusting screw(rod) and fixing clamp handle is provided with inner thread sleeve bolt, the position abutted against of support bar and adjusting screw(rod) can be changed by rotating adjusting screw(rod), and then the opening degree of adjustment movable teeth and fixing tooth, realize the change of biting force and adapt to the polished rod of different-diameter.
Claims (3)
1. a well head safe folder, comprise movable teeth, fixing tooth, activity clamp handle, fixing clamp handle, support bar and adjusting screw(rod), described movable teeth is connected with the head of described activity clamp handle, and be hinged by bearing pin and described fixing clamp handle, described fixing tooth is connected with the head of fixing clamp handle, one end and the activity clamp handle of described support bar are hinged, in the chute that the other end of support bar stretches into fixing clamp handle and along slide, the afterbody bolt of described adjusting screw(rod) and fixing clamp handle, and abut against with the other end of support bar, it is characterized in that: the inner side of described movable teeth and fixing tooth is equipped with bearing tube, the corresponding setting of open side of described bearing tube.
2. a kind of well head safe folder according to claim 1, it is characterized in that, described bearing tube is semicolumn sleeve.
