Abstract
The utility model relates to a tool capable of preventing a pressing cap of a packing box from slipping off, mainly solves the problem existing in the prior art that a person is prone to injury caused by slipping-off of pressing cap of the packing box, and is characterized in that a pipe body (1) is a small-end-down integral whole by fixedly connecting two circular cylinders and a U-shaped opening is arranged in one side wall through an axial center hole. The width of the U-shaped opening is equal to the diameter of the center hole, and a screw hole is arranged vertically in a side wall of the U-shaped opening. The screw hole is internally connected with a screw rod (3), one end of the screw rod (3) is connected with a handle (4), and an anti-slipping sleeve (5) is sleeved on the handle (4). A spacer (2) is arranged on the top surface of the pipe body (1). The tool capable of preventing the pressing cap of the packing box from slipping off enables the pressing cap of the packing box to be free from slipping off, prevents the pressing cap of the packing box from injuring operating personnel by slipping off and guarantees the safety production.
Description
Technical field
The utility model relates to the special tool of a kind of fixedly packing box pressing cap in the oil extraction in oil field technical field, particularly a kind of packing box pressing cap landing instrument that prevents.
Background technology
In the oil extraction in oil field technical field, add on the pumpingh well that to change packing operation be one of the modal work in the normal work on work day of recovering the oil.Because the restriction of thick oil horizontal well and straight well space and condition in adding the packing operating process very easily causes and squeezes the generation of hindering hand and injuring the well head operation injury accidents such as hand by a crashing object.Add at present and change the packing operation iron wires that adopt more and lash packing box pressing cap, when unexpected disconnected the taking off of iron wire, cause the packing box pressing cap landing, injure easily operating personnel's health, dangerous, cause production accident.
Summary of the invention
Technical problem to be solved in the utility model be overcome adding of existing in the background technology when changing the packing operation packing box pressing cap fall to hurt sb.'s feelings easily and cause the problem of security incident, and provide a kind of packing box pressing cap landing instrument that prevents, this prevents packing box pressing cap landing instrument, packing box pressing cap can not be fallen, prevent that packing box pressing cap from injuring operating personnel by a crashing object, guarantee safety in production.
The invention for solving the technical problem can reach by following technical solution: this prevents that packing box pressing cap landing instrument from comprising body, described body is that two up big and down small cylinders are connected to one, have the U-shaped gap by axial center hole to a sidewall, the width of U-shaped gap equals center-hole diameter, vertically have screw on one sidewall of U-shaped gap, connect leading screw in the screw, a termination of leading screw has handle, and cover has Anti-slip cover on the handle; The body end face is equipped with pad.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this prevents packing box pressing cap landing instrument owing to adopt said structure, can be at the fixing packing box pressing cap of oil-extractor polish-rod, packing box pressing cap can not be fallen, prevent that packing box pressing cap from injuring operating personnel's hand by a crashing object.Reduce employee's working strength, increase work efficiency, guarantee safety in production, and easy to operate, time saving and energy saving.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is top views of accompanying drawing 1.
Among the figure: 1-body, 2-pad, 3-leading screw, 4-handle, 5-Anti-slip cover.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this prevents that packing box pressing cap landing instrument from comprising body 1, described body 1 is connected to one for two up big and down small cylinders, have the U-shaped gap by axial center hole to a sidewall, the width of U-shaped gap equals center-hole diameter, vertically has screw on the sidewall of U-shaped gap, connects leading screw 3 in the screw, one termination of leading screw 3 has handle 4, and cover has Anti-slip cover 5 on the handle 4; Body 1 end face is equipped with pad 2, protection body end face, the pressure of buffering packing box pressing cap.
When this prevented that packing box pressing cap landing instrument from using, in polished rod entered the centre bore of body, by rotating handles, the inner of screw mandrel compressed the polished rod outer wall, and body is securely fixed on the polished rod.Body upper support packing box pressing cap.Packing box pressing cap can not landing, prevents that packing box pressing cap from injuring service worker by a crashing object, guarantees safety in production.Two cylinders of body are up big and down small, can make body support better packing box pressing cap.
