Description
Technical field
The present invention relates to cementing concrete plunger pump maintenance tool technical fields, are a kind of cementing concrete plungers pump plunger dismounting
Tool.
Background technique
Plunger is easy to wear when cementing truck works, packing damage, therefore need to often carry out the dismounting work of cementing truck plunger pump.It tears open
It need to start cementing truck when unloading plunger repeatedly；When installing plunger pump, process is tedious, and needs to tap plunger with hammer, not only takes
When it is laborious, security risk is big, be also easy to damage plunger.
Summary of the invention
The present invention provides a kind of cementing concrete plungers pump plunger dismantling devices, overcome the defects of the prior art,
It can effectively solve the problem of plungers pump plunger dismounts plunger time-consuming and laborious and easy to damage.
The technical scheme is that realized by following measures: a kind of cementing concrete plungers pump plunger dismounting work
Tool, including lifting rod and fixed end cap, lifting rod upper outside and lower outside is equipped with screw thread and the two is oppositely oriented mention
Pull rod top is sleeved in fixed end cap and the two is linked together by screw-driven, and fixed end cap lower outside is equipped with spiral shell
Line.
Here is the further optimization and/or improvements to invention technology described above scheme:
Above-mentioned lifting rod top is equipped with radial through-hole, removable in radial through-hole to be equipped with operating stick.
Anti-slip layer is equipped on the outside of aforesaid operations bar.
The above-mentioned fixing end portion of covering is equipped with boss, and boss section is in quadrangle or hexagon.
Above-mentioned lifting rod top screw thread is trapezoidal coarse thread.
Structure of the invention is reasonable and compact, easy to use, and plunger, which is carried out dismounting, by screw-driven can make plunger stress
Uniformly, it avoids plunger and damages deformation in disassembly process, operation is time saving and energy saving.Screw thread is set simultaneously in fixed end cap lower outside
And link together with plunger case, for lifting rod spiral and lift plunger and provide effective support and fix；Lifting rod
Upper outside and lower outside be equipped with the oppositely oriented of screw thread and the two, the lower part of lifting rod and plunger upper part screw thread connect
It is connected together, since the thread rotary orientation of lifting rod upper and lower part is opposite, it is therefore prevented that mentioned when upward spiral lifts plunger
Pull rod falls off with plunger；Fixed end cap lower part links together with the internal screw thread at plunger case installation gland position, makes full use of
Existing screw thread realizes that the fixation with plunger case keeps structure of the invention more compact on plunger case；In addition, lifting rod and fixation
End cap is to be threadedly coupled, and can be dismantled after use, easy to use, easy to carry.
Detailed description of the invention
Attached drawing 1 is the main view half section schematic of preferred embodiment.
Coding in attached drawing is respectively as follows: 1 for lifting rod, and 2 be fixed end cap, and 3 be plunger case, and 4 be plunger, and 5 be operating stick,
6 be boss.
Specific embodiment
The present invention is not limited by the following examples, can determine according to the technique and scheme of the present invention with actual conditions specific
Embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to Figure of description 1
Butut mode be described, such as: front, rear, top, and bottom, left and right positional relationship be the Butut according to Figure of description
Direction determines.
Below with reference to examples and drawings, the invention will be further described:
As shown in Fig. 1, which includes lifting rod 1 and fixed end cap 2, on lifting rod 1
On the outside of portion and lower outside is equipped with screw thread and the two is oppositely oriented, and 1 top of lifting rod is sleeved in fixed end cap 2 and two
Person is linked together by screw-driven, and fixed 2 lower outside of end cap is equipped with screw thread.
When operation, 1 lower part of lifting rod is connected to by screw thread and 4 top of plunger after the dismounting of cementing truck pressing cover of plunger piston pump
Together, then the internal screw thread that fixed 2 lower part of end cap is installed at gland position with plunger case 3 is linked together, turn lifting rod
1, plunger 4 is lifted out upwards from plunger case 3, completes plunger 4 by spiral under the action of fixed end cap 2 of lifting rod 1
Disassembly, similarly, opposite direction turn lifting rod 1 when plunger 4 is installed.The present invention is dismounted plunger 4 by screw-driven
It can make 4 uniform force of plunger, avoid plunger 4 and damage deformation in disassembly process, operation is time saving and energy saving.Under fixed end cap 2
Setting screw thread and link together with plunger case 3 on the outside of portion, for lifting rod 1 spiral and lift plunger 4 and provided
The support of effect is fixed；The upper outside and lower outside of lifting rod 1 are equipped with oppositely oriented, the lifting rod 1 of screw thread and the two
Lower part be threaded togather with 4 top of plunger, since the thread rotary orientation of 1 upper and lower part of lifting rod is opposite, it is therefore prevented that
There is lifting rod 1 when upward spiral lifting plunger 4 to fall off with plunger 4；Fixed 2 lower part of end cap and plunger case 3 install gland position
The internal screw thread at place links together, and the fixation for making full use of existing screw thread on plunger case 3 to realize with plunger case 3 makes of the invention
Structure is more compact；It in addition, lifting rod 1 is to be threadedly coupled with fixed end cap 2, can be dismantled, be used after use
It is convenient, easy to carry.
Above-mentioned cementing concrete plungers pump plunger dismantling device can be made further optimization and/or improvements according to actual needs:
As shown in Fig. 1,1 top of lifting rod is equipped with radial through-hole, removable in radial through-hole to be equipped with operating stick 5.Thus
It is more labor-saving when dismounting plunger 4, reduce labor intensity.In addition, operating stick 5 is removable, it is easy to use, easy to carry.
As shown in Fig. 1, anti-slip layer is equipped on the outside of operating stick 5.As needed, anti-slip layer can be rubber sleeve or embossing, prevent
It only acts on and being slided in personnel's operating process, or even cause safety accident.
As shown in Fig. 1, fixed 2 top of end cap is equipped with boss 6, and 6 section of boss is in quadrangle or hexagon.In use,
6 outside of boss can be stuck in spanner and rotate to fixed end cap 2 is threaded togather it with plunger case 3, easy to use.
According to actual needs, it directly can also directly be accommodated with large-scale spanner in fixed 2 lower part of end cap for the installation of fixed end cap 2
Turn fixed end cap 2 in outside realizes its installation.
As shown in Fig. 1,1 top screw thread of lifting rod is trapezoidal coarse thread.Lifting rod 1 is by trapezoidal coarse thread and admittedly
Fixed end lid 2 is sequentially connected together, effectively increases the mechanical strength of lifting rod 1, prevents spiral shell occur in lifting plunger 4 upwards
The case where line damages.
The above technical characteristic constitutes highly preferred embodiment of the present invention, with stronger adaptability and best implementation effect
Fruit can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
