Gaps may also appear in the connection between the bracket and the mounting foundation, leading to a significant decrease in overall stability.

Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, and in particular relates to a cylinder head support fixture for a reciprocating compressor. Background Technology

[0002] During the operation of a reciprocating compressor, the cylinder head, as a core component, must withstand multiple loads such as periodic gas pressure impact, piston side thrust, and vibration. Its installation stability directly affects the compressor's sealing performance, operating accuracy, and service life. Traditional cylinder head support fixtures have many limitations in practical applications, becoming a pain point that restricts the efficient and stable operation of the equipment.

[0003] However, existing support fixtures often use single bolt fastening or simple bracket support during use, resulting in few and unevenly distributed support points and limited contact surface with the installation foundation. This makes it difficult to form a stable multi-point support structure. When the compressor generates periodic vibrations during operation, stress concentration is likely to occur. Over time, the bolts are prone to loosening due to continuous vibration, and gaps may also appear in the connection between the bracket and the installation foundation, leading to a significant decrease in overall stability. Utility Model Content

[0004] The purpose of this utility model is to provide a cylinder head support fixture for a reciprocating compressor. By setting up a support part, it solves the problems of existing support fixtures, which mostly use a single bolt fastening or simple bracket support during use. These support points are few and unevenly distributed, and the contact surface with the installation foundation is limited, making it difficult to form a stable multi-point support structure. When the compressor generates periodic vibrations during operation, stress concentration is likely to occur. Over time, the bolts are prone to loosening due to continuous vibration, and gaps may also appear in the connection between the bracket and the installation foundation, resulting in a significant decrease in overall stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a cylinder head support fixture for a reciprocating compressor, comprising a mounting plate and a fixing ring disposed above the mounting plate. A reciprocating compressor is fixedly connected to the inner wall of the fixing ring. The fixture also includes: a support portion mounted on the mounting plate; several locking portions disposed on the mounting plate; a connecting assembly mounted on the mounting plate; and several moving components disposed on the connecting assembly. The connecting assembly includes a fixing plate disposed on the top of the mounting plate. Several mounting slots are formed on the fixing plate and the mounting plate, each containing a threaded rod that passes through one of the mounting slots. Adjusting elements are provided on each threaded rod. The fixing plate and the fixing ring are fixedly connected, the threaded rods and mounting slots are arranged in an array, and the fixing plate is in contact with the mounting plate. Each adjusting element includes a limiting block threaded to the outer wall of the threaded rod, which is in contact with the fixing ring. The limiting block is hexagonal in shape.

[0006] Furthermore, the locking part includes a limiting component mounted on the connecting component; and a limiting component disposed on the connecting component; wherein both the limiting component and the limiting component are located above the mounting plate.

[0007] Furthermore, the motion component includes a fixing ring 1 sleeved on the outer wall of the threaded rod. A plurality of hinge blocks 1 are fixedly connected to the outer wall of the fixing ring 1. Each of the hinge blocks 1 has a hinge rod hinged to its opposite side. Each of the hinge rods has a hinge block 2 hinged to its opposite side. A spreading member is provided on the threaded rod. The hinge blocks 1, hinge rods, and hinge blocks 2 are arranged in a circumferential array. The spreading member includes a fixing ring 2 fixedly connected to the outer wall of the threaded rod. A plurality of hinge blocks 3 are fixedly connected to the outer wall of the fixing ring 2. Each of the hinge blocks 3 has a support rod hinged to its opposite side. Each of the hinge blocks 2 is fixedly connected to a support rod. The hinge blocks 3 and support rods are arranged in a circumferential array.

[0008] Furthermore, the limiting component includes several limiting grooves formed on the threaded rod, a pressure ring is provided on the outer wall of the threaded rod, and a hexagonal block is threadedly connected to the outer wall of the threaded rod; wherein the hexagonal block is hexagonal in shape, and the limiting grooves are distributed in a linear array.

[0009] Furthermore, the limiting component includes a plurality of locking grooves formed on the hexagonal block, with a limiting rod passing through the locking groove and the limiting rod passing through the limiting groove; wherein the locking groove and the limiting rod are slidably connected.

[0010] This utility model has the following beneficial effects: 1. By setting up a support part, when the threaded rod is inserted into the mounting slot, the support rod is squeezed inward by the inner wall and retracts. The attitude adjustment is completed by the cooperation of the hinge block and the hinge rod to ensure that the threaded rod is inserted smoothly. After insertion, the support rod unfolds outward under its own elasticity or structural reset characteristics until the fixing ring contacts the limit block to form a rigid limit, avoiding over-extension. Finally, the threaded rod is pulled upward to make the unfolded support rod fit tightly against the bottom of the mounting plate. After the support rod unfolds, the contact surface with the mounting plate forms multi-point support. With the rigid constraint of the limit block, it can effectively resist the vibration and displacement of the compressor during operation and prevent loosening. 2. By setting up the system, the pressure ring is fitted onto the outer wall of the threaded rod and slides down to contact the limiting block. Initial axial positioning is formed through the contact and limiting, providing a stable reference for subsequent tightening. Then, the hexagonal block is tightened along the thread of the threaded rod and contacts the pressure ring. The self-locking characteristic of the thread generates continuous pressure, tightly fitting the pressure ring and the limiting block, further strengthening the axial constraint and preventing the threaded rod from axially moving due to vibration. Finally, the limiting rod is inserted into the corresponding limiting groove and locking groove and the end is bent. The mechanical clamping principle forms a double limit in the radial and circumferential directions, blocking the rotational loosening path of the threaded rod and fundamentally preventing threaded connection failure. The multi-stage locking structure forms a closed-loop constraint from multiple dimensions of axial, radial, and circumferential. Even in the high-frequency vibration environment of the compressor, it can effectively resist external impact and prevent the threaded rod from loosening or falling off.

Several hinge blocks 226 are fixedly connected to the outer wall. Support rods 227 are hinged to the sides of the hinge blocks 226 that are far apart from each other. Several hinge blocks 224 are fixedly connected to the support rods 227 respectively. The hinge blocks 226 and support rods 227 are arranged in a circumferential array.

[0018] A specific application of this embodiment is as follows: In use, first place the fixing plate 211, the fixing ring 112 on it, and the reciprocating compressor 113 on the mounting plate 111.
