Large reciprocating compressors play a very extensive and important role in the pillar industries of the national economy, such as the coal industry, petroleum industry, energy industry, chemical industry and other industries. They are one of the indispensable key equipment in various process industries.

[0003] Reciprocating compressor dynamic equipment needs to disassemble the cross pin for inspection during daily inspection and maintenance as well as emergency repairs. Due to the large size of the crankcase of the equipment and the weight of the cross head of nearly three or four hundred pounds, and the narrow working environment, the usual disassembly and inspection is done by multiple people using a guide rod less than 1.2 meters in length and a crane. The steps are as follows: after the guide rod is connected to the cross pin, it is lifted at the middle end of the guide rod by the crane, and the other end is adjusted to the hole by multiple people pressing the guide rod. In this process, the cross pin often falls off or the operator's hand is injured due to fatigue. Utility Model Content

[0006] Preferably, the lifting mechanism includes a servo motor, a lifting screw and a screw nut. The servo motor is installed inside the mounting groove, the lifting screw is installed at the driving end of the upper end of the servo motor, and the outer end of the lifting screw is connected to the screw nut.

[0007] Preferably, a controller is installed on the outer end of the support column, and the controller is electrically connected to the servo motor.

[0008] Preferably, a slide groove is provided at the right end of the loading platform, and a slider is connected to the interior of the slide groove.

[0009] Preferably, a cleaning brush is installed on the left end of the sliding block, and the cleaning brush is located below the sliding wheel.

[0010] Preferably, a mounting frame is installed at the lower end of the device base, a universal wheel is installed at the lower end of the mounting frame, and a foot brake pad is installed above the universal wheel.

[0011] Preferably, the number of the sliding wheels is five, and the intervals between the sliding wheels are the same.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This disassembly and inspection tool for disassembling and assembling the cross pin of a large reciprocating compressor uses a servo motor, a lifting screw and a screw nut provided by a lifting mechanism. When in use, the servo motor is first started, and the lifting screw is driven by the servo motor to rotate, so that the screw nut drives the loading platform to rise, which is convenient for lifting the loading platform to a height suitable for installation. The cross pin is then hoisted onto the loading platform by a crane, and finally the worker pushes the cross pin. The setting of multiple sliding wheels makes it easy to push the cross pin to the installation location for installation. This device greatly shortens the operation time cycle, liberates the labor intensity of the operator, ensures personal safety, and improves the practicality of the disassembly and inspection tool for disassembling and assembling the cross pin of a large reciprocating compressor.

[0014] 2. The disassembly and inspection tool for disassembling and assembling the cross pin of a large reciprocating compressor is provided with a slide groove, a slider and a cleaning brush. When dust and impurities fall under the sliding wheel during use, the slider can be manually pushed to drive the cleaning brush to move, so that the dust and impurities are pushed out from the loading platform and cleaned up by the cleaning brush. There is no need to remove the sliding wheel for cleaning, which can effectively prevent excessive dust and impurities from affecting the rolling of the sliding wheel, thereby improving the use effect of the disassembly and inspection tool for disassembling and assembling the cross pin of a large reciprocating compressor.
