Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm compressors, in particular to a supporting device for a cylinder head of a diaphragm compressor. Background Art

[0002] The diaphragm compressor is a special type of positive displacement compressor. It mainly uses a motor to drive the crank-connecting rod mechanism to convert the rotational motion of the crankshaft into the reciprocating linear motion of the connecting rod, pushing the piston at the end of the connecting rod to also do reciprocating linear motion, thereby pushing the hydraulic oil in the cylinder head to compress the gas on the diaphragm side.

[0003] The entire compressor body is viewed from the outside, as shown in the attached Figure 2 As shown, the diaphragm compressor is divided into three parts: a cylinder head 21, a middle body 22, and a housing 23. The cylinder head is connected to the housing through the middle body to form a cantilever beam structure. The crank-connecting rod piston mechanism is located in the middle body and the housing. Due to its metal material and large size, the cylinder head is generally heavy. During long-term operation of the equipment, under the action of gravity and periodic vibration, the cylinder head will generate a large torque on the middle body and the middle body connection, thereby damaging the middle body and its connecting parts. Therefore, it is necessary to increase support for the cylinder head to balance the torque generated by the cylinder head's gravity and reduce vibration. To this end, a support device for a diaphragm compressor cylinder head is proposed. Utility Model Content

[0007] The support mechanism includes a welding pad, a stud, a sleeve and a nut. The welding pad is welded on the skid-mounted chassis. The sleeve and the welding pad are connected by four bolts. The sleeve is connected to the lower end of the stud by a thread. The top of the stud is connected to the nut by a thread.

[0008] Preferably, the top of the stud is connected to an upper nut through a thread, and the top surface of the upper nut fits with the bottom surface of the nut; the bottom position of the stud is connected to a lower nut through a thread, and the bottom surface of the lower nut fits with the sleeve.

[0009] Preferably, the upper nut and the lower nut are both hexagonal nuts.

[0011] Preferably, a through hole is arranged at the center of the welding pad, and the diameter of the through hole is larger than the diameter of the stud.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1、The utility model discloses support convenient to use, only need to use the torque wrench to rotate the lower nut, because the lower nut is unable to move downward with the sleeve, then the stud moves upward along the vertical direction under the action of reaction force, makes the upper surface of the nut and the outer circle of the cylinder head completely close, realizes the support effect.

[0014] 2、The utility model discloses support mechanism's each spare part are simple structure spare, and simple processing, and the spare part damage is convenient to replace, and support mechanism overall size is smaller, and use does not occupy space, passes through the threaded connection with the pry loading chassis fixed, and the fixed and dismounting operation is simple, and four bolts are loosened and can complete dismounting.
