Through above-mentioned technical scheme, general oil pipe all is circularly, and oil pipe protective sheath hole is circularly, can carry out better restraint to oil pipe, reduces oil pipe's swing range, the striking that produces when reducing oil pipe and oil pipe protective sheath striking.
Preferably, the reamer part is circular.
Through above-mentioned technical scheme, the reaming part is circular can with oil pipe protective sheath phase-match, and the round hole processing is comparatively convenient simultaneously. Meanwhile, the influence on the strength of the whole structure of the large cover plate is small, points with concentrated stress are not easy to generate on the large cover plate, and the whole strength is reduced.
Preferably, both ends of the mounting hole are arc-shaped.
Through above-mentioned technical scheme, the mounting hole sets up like this and makes can laminate inseparabler between oil pipe installation cover and the mounting hole to reduce the activity space of oil pipe protective sheath, increase lifting surface area, reduce the wearing and tearing between oil pipe protective sheath self and the big apron.
Preferably, the middle part of the limiting part is provided with an arc-shaped groove attached to the flanging.
Through above-mentioned technical scheme, the setting up of arc wall makes the oil pipe protective sheath can conflict with the locating part better to the installation more firm.
Preferably, the joint of the reaming part and the mounting hole is provided with a fillet.
Through above-mentioned technical scheme, the setting up of fillet makes the oil pipe protective sheath can enter into the mounting hole both ends comparatively easily when the installation, is difficult for taking place jamming, fish tail, passes through the fillet simultaneously, is difficult for producing stress concentration.
Preferably, the limiting member is fixed on the outer side of the large cover plate through a screw.
Through the technical scheme, the limiting part is fixed through the screw, and the installation and the disassembly are convenient.
Compared with the prior art, the utility model has the beneficial effects that: through improving the structure of mounting hole for in the oil pipe protective sheath need not to take place great deformation and just can install the mounting hole when the installation, easy to assemble, the change of being convenient for.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
As shown in figures 1-5, the breaking hammer for reducing the abrasion of an oil pipe comprises a shell 1 formed by welding steel plates. The shell 1 comprises a large cover plate 2, a mounting hole 3 is formed in the large cover plate 2, and the mounting hole 3 penetrates through the large cover plate 2. Two oil pipe protective sleeves 4 are installed in the installation hole 3, and the oil pipe is arranged in the oil pipe protective sleeves 4 in a penetrating mode. The inner hole of the oil pipe protective sleeve 4 is circular, two ends of the oil pipe protective sleeve 4 are provided with circular flanges 5, and a groove 6 is formed between the two flanges 5. The oil pipe protective sleeve 4 is clamped in the mounting hole 3 through the groove 6.
The mounting hole 3 is rectangular form, and two oil pipe protective sheaths 4 are installed respectively in the one end of mounting hole 3. The middle of the mounting hole 3 is provided with a hole expanding part 7 which is convenient for the flanging 5 to pass through the mounting hole 3, the hole expanding part 7 is circular, the cross section of the hole expanding part 7 is larger than or equal to the cross section of the flanging 5 on the oil pipe mounting hole 3, so that the oil pipe protective sleeve 4 does not need to deform when one end of the oil pipe protective sleeve 4 passes through the large cover plate 2. The round angle 10 is arranged at the joint of the hole expanding part 7 and the mounting hole 3, so that the oil pipe mounting sleeve can conveniently slide from the hole expanding part 7 to the end part of the mounting hole 3, and clamping stagnation is reduced. Meanwhile, the transition is carried out at the position through the round angle 10, the overall structural strength of the large cover plate 2 can be increased, stress concentration at the position is avoided, and the overall structural strength and the practical service life of the large cover plate 2 are greatly influenced.
