Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
The bottom plate assembly 1 comprises a detachable assembling beam, the assembling beam comprises two identical frame beams 11 shaped like a Chinese character 'hui', the two frame beams 11 shaped like the Chinese character 'hui' are symmetrically connected through two connecting beams 12, and an oil supporting disc 13 is movably clamped between the connecting beams 12. When the bottom plate assembly 1 is manufactured, only two parts, namely the square frame beam 11 and the connecting beam 12, need to be manufactured, and the design is convenient to manufacture and maintain. When one part of the bottom plate assembly 1 is damaged, the corresponding part can be detached from other standby detaching platforms for replacement. The left end and the right end of the bottom plate are designed into symmetrical structures, the two ends of the bottom plate can be connected with the bottom plate of the supporting upright post 2, when the frame beam 11 with the shape of Chinese character 'hui' at one end is damaged, the frame beam 11 with the shape of Chinese character 'hui' at the other end can be used for installing the supporting upright post 2, and the service life of the bottom plate can be prolonged by the design.
The support upright post 2 comprises a lower upright post 21 fixedly connected with the frame beam 11 shaped like a Chinese character 'hui', and a bottom plate of the lower upright post 11 is detachably connected on the frame beam 11 shaped like a Chinese character 'hui' through a bolt group. An upper upright post 22 is arranged in a splicing and matching way with the lower upright post 21, and a lifting mechanism 4 for supporting the upper upright post 22 to lift is arranged in the lower upright post 21.
The lifting mechanism 4 comprises a screw rod 41 rotatably arranged in the lower upright post 21, and the upper end of the screw rod 41 is adjustably connected with the bottom plate of the upper upright post 22 through a single-line trapezoidal thread. The screw transmission is realized by a screw pair consisting of a screw rod and a nut, and is mainly used for converting rotary motion into linear motion and simultaneously transmitting motion and power. According to the relative motion relationship between the screw and the nut, the general motion forms of the screw transmission are mainly two types: firstly, the screw rotates, the nut moves, and the nut is mostly used in a feeding mechanism of a machine tool; and secondly, the nut is fixed, the screw rod rotates and moves, and the screw jack is mainly used for a screw jack.
The lifting mechanism 4 of the embodiment is mainly used for lifting the upper upright post 22, and the axial force born by the lifting mechanism is large, but the required thread transmission precision is not high. If the lifted upper upright post 22 cannot be self-locked, the upper upright post 22 will have a tendency to fall under the gravity of the engine, which will affect the normal work of the operators and even cause safety accidents. Therefore, the lifting mechanism 4 has extremely high requirements on self-locking performance, the thread transmission of the single trapezoidal thread has very ideal self-locking performance, and the self-locking performance requirements of the lifting mechanism are met.
The lower end of the screw rod 41 is fixedly provided with a straight bevel gear 42 through a key, and the straight bevel gear 42 is arranged at the bottom end of the lower upright post 21 in a transmission way. A driving bevel gear 43 is arranged in a meshed manner with the straight bevel gear 42, and a lifting hand wheel 44 fixedly connected with the driving bevel gear 43 is arranged on the outer side of the lower upright post 21. The lifting hand wheel 44 can be rotated manually to drive the driving bevel gear 43 to rotate, the driving bevel gear 43 rotates to drive the straight bevel gear 42 to rotate, the straight bevel gear 42 drives the screw rod 41 to rotate, and the screw rod 41 rotates to drive the upper upright post 22 to ascend or descend.
The straight bevel gear 42 is selected in the present embodiment for two reasons: firstly, the straight bevel gear 42 is compact and is convenient to install in the lower upright post 21. The lifting mechanism 4 of the embodiment is arranged in the lower upright post 21, has limited space and can only use gear transmission; secondly, the bevel gear transmission can change the transmission direction, so that the lifting hand wheel 44 can be reasonably arranged. In addition, the ninety-degree crossed-axis bevel gear transmission effectively reduces the transverse size of the mechanism, so that the mechanism is more compact in structure.
The screw 41 and the lifting hand wheel 44 are driven by gears, mainly used for transmitting the torque for rotating the screw 41, and the straight bevel gear 42 with simpler design and manufacture is selected because the torque transmitted by the gears is not large, the load is smaller, and the transmission direction is required to be changed according to the requirements of the working environment. Because the torque transmitted by the spur bevel gear 42 is not large, a closed drive is used, and therefore various failure modes of gear teeth and tooth surfaces do not need to be considered. The straight bevel gear 42 is adopted for transmission, and the requirements on strength, precision and speed are not high. The gear is made of forged steel, so that the gear is convenient to cut and the cutter is not easy to wear rapidly, and the gear is provided with a soft tooth surface. And (3) cutting the gear blank into teeth after normalizing or quenching and tempering, wherein the precision is only required to be 8 grades during cutting.
The turnover mechanism is arranged at the top end of the upper upright post 22, the turnover mechanism 3 comprises a worm gear shaft 31 which is horizontally and rotatably arranged in the upper upright post 22, the outer end part of the worm gear shaft 31, which is positioned in the upper upright post 22, is connected with a turnover arm, a worm gear 32 is arranged at the position of the worm gear shaft 31, which is positioned in the upper upright post 22, a worm 33 is arranged in transmission fit with the worm gear 32, the helix lead angle of the worm 33 is smaller than the equivalent friction angle of the meshing surface of the worm gear 32, and the end part of the worm 33, which. The manual turning hand wheel 34 can drive the worm 33 to rotate, the worm 33 rotates to drive the worm wheel 32 to rotate, the worm wheel 32 drives the worm wheel shaft 31 to rotate, and the worm wheel shaft 31 drives the turning arm to turn the engine.
The turning of the turning arm is realized by selecting a worm gear and a worm gear, and the three reasons are as follows: the worm transmission can realize a large transmission ratio, realize speed reduction and labor saving, and has a compact structure; secondly, the worm transmission can realize self-locking under the condition of meeting a certain meshing condition, namely the helix lead angle of the worm 33 is smaller than the equivalent friction angle of the meshing surface of the worm wheel 32, so that the engine can be fixed at any angle by the turnover arm, and the work of operators is greatly facilitated; thirdly, the worm gear is used in the turnover mechanism to effectively overcome the defects. Because the turnover mechanism has very low rotating speed in the using process and is in closed transmission, the working environment is better, and the excessive abrasion and the heating of parts are avoided. Although the worm transmission has a greatly low transmission efficiency under the condition of self-locking, the turnover mechanism 3 is not turned over frequently in operation, and the torque required for turning over is not large.
The overturning arm comprises an overturning plate 35 connected with the outer end of the worm gear shaft 31, a connecting cylinder 36 is arranged on one side of the overturning plate 35 close to the worm gear shaft 31, a fastening screw 37 pressing the worm gear shaft 31 is arranged on the side wall of the connecting cylinder 36, and four strip-shaped through grooves 38 which are crossed to form 90 degrees and used for locking engine bolts are formed in the overturning plate 35.
