Embodiment 1

[0020] Such as figure 1 As shown, this embodiment includes a supporting frame and a hanging board 1, the bottom of the hanging board 1 is connected with the supporting frame, a plurality of U-shaped notches 2 are symmetrically arranged around the surrounding of the hanging board 1, and a The lifting mechanism 6 also includes a switch door arranged on the hanging plate 1 . The hanging plate 1 is welded with the bottom of the supporting frame to form a whole, and a plurality of U-shaped notches 2 are symmetrically arranged around the hanging plate 1 for engaging and fixing the main bearing, so as to provide a stable suspension for the main bearing. The frame structure and the three-dimensional suspension reduce the occupation of the ground area by multiple main bearings; the lifting mechanism 6 installed at the bottom of the support frame can freely adjust the height of the hanging plate 1 from the ground when the main bearing is placed manually, which is convenient for the main...

Embodiment 2

[0022] Such as figure 1 As shown, in this embodiment, on the basis of Embodiment 1, the support frame includes a leg A3 and a leg B4, and the lifting mechanism 6 is installed on the bottom of the leg A3 and the leg B4, and the tripod 5 is passed between the leg A3 and the leg B4. connect. According to the stability of the triangle, a triangle fixing frame 5 is installed between the supporting feet A3 and the supporting feet B4, which improves the stability of the supporting frame; the separately arranged supporting feet A3 and B4 can share the bearing capacity on the hanging board 1; the supporting feet A3 Lifting mechanisms 6 are respectively provided at the bottom of the legs B4, and when the main bearing needs to be stored or taken, the two lifting mechanisms 6 can be adjusted at the same time to adjust the height of the hanging plate 1, which is fast and labor-saving.

Embodiment 3

[0024] Such as figure 1 As shown, in this embodiment, on the basis of Embodiment 1, the distance between the U-shaped notches 2 is 10-15 cm. In order to avoid the mutual extrusion between the main bearings when placed, a certain distance is set between the U-shaped notches 2; when the distance is less than 10cm, the main bearings suspended side by side will be mutually extruded, resulting in the failure of access. Inconvenient; when the spacing is greater than 15cm, the number of main bearings that can be suspended simultaneously on the hanging plate 1 is reduced, resulting in a reduction in the practicability of the hanging plate 1.

Abstract

The invention discloses a bearing setting mechanism. The bearing setting mechanism comprises a support rack and a hanging plate. The bottom of the hanging plate is connected with the support rack, the periphery of the hanging plate is symmetrically provided with a plurality of U-shaped notches, and the bottom of the support rack is provided with a lifting mechanism. The bearing setting mechanism also comprises a switch door. When being set or taken off, a main bearing on the support rack can easily slide out of the U-shaped notches along with the shake of the support, the switch door can limit and lock the main bearing inside the U-shaped notches, so that the stability of the main bearing and the safety and reliability of manually setting and taking off the main bearing can be guaranteed.

Description

technical field [0001] The invention relates to the field of natural gas compressor manufacturing, in particular to a bearing placement mechanism. Background technique [0002] There are many types of piston compressors with complex structures, but the basic structure is roughly the same, mainly composed of fuselage, crankshaft, connecting rod, piston, cylinder and suction, exhaust valve, crosshead, slideway, piston rod and stuffing box, etc. When the compressor is running, the motor drives the crankshaft to rotate, and the piston reciprocates through the connecting rod. [0003] In the production process of natural gas compressors, the main bearings of the crankshaft and connecting rod mechanism of the compressor are stacked randomly. Assembly place, which reduces the space occupation of the assembly workshop; but the labor intensity of workers will be greatly enhanced during the handling process, and there is a certain distance between the placement place and the asse...
