    • Provided is an angular beam connecting apparatus. Angular beams are various types of angular beams with at least one groove that includes inner walls formed on both sides of the groove. The connecting apparatus assembled in the at least one groove of the respective angular beams includes: an upper member having at least one first pressing hole formed therein and at least one first inclined surface formed therein; a lower member a second pressing hole formed therein in correspondence to the first pressing hole and a second inclined surface formed therein while facing the first inclined surface; pressure units that are screwed through the first and second pressing holes of the upper and lower members; at least one pressure rod located in the space “a” formed between the first and second inclined surfaces by placing the first and second inclined surfaces of the upper and lower members to face each other, wherein the pressure units of the connecting member penetrate the first and second pressing holes to have the upper and lower members closely contact each other, and the at least one pressure rod located in the space “a” between the first and second inclined surfaces is pushed outward to fix two angular beams and to extend the length of the structure formed by the two angular beams.

    • The present invention discloses a petroleum instrument salvaging connector, which is set on a salvage end of a petroleum instrument, for being in hooking fit with a salvaging head of a petroleum instrument salvaging device. The petroleum instrument salvaging connector comprises a salvaging connector body (11); the salvaging connector body (11) has a stair-shaped salvaging hole; the stair-shaped salvaging hole is a blind hole and comprises a large-caliber section (111) and a small-caliber section (112); the large-caliber section (111) is located at the bottom of the stair-shaped salvaging hole, and a hooking face (113) facing the bottom of the large-caliber section (111) is formed at the jointing part between the large-caliber section (111) and the small-caliber section (112); and a sand outlet (116) is set at the bottom of the sidewall of the large-caliber section (111). The invention further discloses a petroleum instrument. By employing the above solutions, the problem in the current drilling process may be solved that the salvaging head cannot be in hooking fit with the petroleum instrument salvaging connector due to the deposition of solid particles in the slurry in the stair-shaped salvaging hole of the petroleum instrument salvaging connector.
    • 本发明公开了一种石油仪器回收连接器,其设置在石油仪器的回收端上,用于与石油仪器回收装置的回收头钩住配合。 石油仪器回收连接器包括回收连接器主体(11); 救助连接器主体(11)具有台阶形的救助孔; 台阶形的打捞孔是盲孔,包括大口径部分(111)和小口径部分(112); 大口径部分111位于阶梯式救助孔的底部,并且在大口径部分111的接合部分形成面向大口径部分111的底部的钩面113。 口径部分(111)和小口径部分(112); 并且砂出口(116)设置在大口径部分(111)的侧壁的底部。 本发明还公开了一种石油仪器。 通过采用上述解决方案,可以解决当前钻孔过程中的问题,即由于固体颗粒沉积在石英仪器回收连接器的楼梯形回收孔中的浆料中,回收头不能与石油仪器回收连接器配合 石油仪器救生连接器。
