Description

Technical Field

[0001] This utility model belongs to the field of assembly tools for large reciprocating compressors, and specifically relates to a reciprocating compressor side cover mounting device. Background Technology

[0002] In industrial applications, large reciprocating compressors, such as the 4M80 model, are key power equipment widely used in industries such as petrochemicals and natural gas processing. These compressors have complex structures and large sizes, especially their side covers (750mm long, 650mm wide), which are numerous (approximately 16). Maintenance and repair require disassembling and reassembling these side covers one by one to inspect or replace internal components. Traditional disassembly and reassembly processes rely on large overhead cranes to move heavy objects, but this process presents many inconveniences.

[0003] On-site management difficulties: Due to the large number and weight of the side covers, after disassembling them one by one using a large overhead crane, the side covers are easily scattered and placed in a messy manner, which brings great challenges to the subsequent cleanup work.

[0004] Lack of standardization: The inability to achieve effective standardized and unified management on-site affects maintenance efficiency and quality control.

[0005] Safety hazards: If an accident occurs during the operation of a large overhead crane, it may pose a threat to the safety of the staff.

[0006] Increased time costs: Traditional methods are time-consuming, increasing overall downtime and maintenance costs.

[0007] Based on this, the present invention proposes a side cover mounting device for a reciprocating compressor. Utility Model Content

[0008] In order to solve the above-mentioned problems in the prior art, namely the difficulties in site management, lack of standardization, safety hazards and increased time costs in the installation of reciprocating compressor side covers, the present invention provides a reciprocating compressor side cover installation device, including a base plate and a storage rod;

[0009] At least one row of storage rods is installed on the base plate, and multiple storage rods in each row are arranged along the length of the base plate;

[0010] A reciprocating compressor side cover is placed between two adjacent storage rods.

[0011] Furthermore, the base plate is fixed to the main frame, and the main frame is fixed to the lifting lugs.

[0012] Furthermore, the main frame includes a first crossbeam, a first longitudinal beam, a second crossbeam, a second longitudinal beam, and connecting rods;

[0013] One end of the first crossbeam is fixed to one end of the first longitudinal beam, the other end of the first longitudinal beam is fixed to one end of the second crossbeam, and the other end of the second crossbeam is fixed to one end of the second longitudinal beam.

[0014] Both ends of the first and second crossbeams are fixed to one end of the connecting rod, and the other end of the connecting rod is fixed to the base plate.

[0015] Furthermore, both ends of the first and second crossbeams are fixed to lifting lugs, which are used to connect to external handling devices.

[0016] Furthermore, at least one row of storage rods is installed on the base plate, with the following specific structure:

[0017] Each of the storage rods is mounted on a locking device located inside a slider, which is positioned within and moves along a guide groove on a base plate. The locking device is used to lock the slider in its position within the guide groove.

[0018] Furthermore, the slider and the guide groove are in the shape of a dovetail, I-shaped, or T-shaped structure that fits each other.

[0019] Furthermore, multiple casters are mounted on the base plate.

[0020] Furthermore, the caster wheel is equipped with a braking device.

[0021] Furthermore, a lifting ring is fixed on the side cover of the reciprocating compressor, and the lifting ring is connected to the overhead crane via a mother-daughter chain.

[0022] The beneficial effects of this utility model are:

[0023] Improve on-site management efficiency: The device, through the design of the base plate and the placement rod, places the side covers in an orderly manner in designated positions, reducing on-site clutter and improving on-site management efficiency.

[0024] Achieving standardized management: The fixed structure of the device ensures that the side cover is installed in the same way every time it is maintained, which helps to standardize the maintenance process and improve the level of maintenance quality control.

[0025] Enhanced safety: It reduces the number of times the side cover is directly moved by the large overhead crane, reduces the risk of accidents that may occur during operation, and ensures the safety of the staff.

[0026] Reduced time costs: The simplified side cover disassembly and assembly process reduces downtime and maintenance cycles, thereby lowering overall maintenance costs.

[0027] Flexibility and adaptability: The storage rod is mounted on a locking device, which is located inside the slider. The slider can move within the guide groove. This design allows the storage device to adjust the distance between the side covers according to actual needs, adapting to side covers of different sizes, thus increasing the flexibility and applicability of the device.

[0028] Easy to move: The base plate is equipped with casters, and the casters are equipped with brakes, which makes the entire device easy to move to the required position and can be stably fixed, further improving the ease of use.

[0029] Integrated lifting ring design: Lifting rings are fixed on the side cover and connected to the overhead crane via a mother-daughter chain, which not only simplifies the lifting process but also ensures the safety and accuracy of the lifting process. Attached Figure Description

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] like Figures 1-7 As shown, see details. Figure 1 , Figure 2 and Figure 4 This utility model provides a reciprocating compressor side cover mounting device, including a base plate 1 and a mounting rod 2;

[0041] At least one row of storage rods 2 is installed on the base plate 1, and multiple storage rods 2 in each row are arranged along the length direction of the base plate 1;

[0042] A reciprocating compressor side cover 3 is placed between two adjacent storage rods 2.

[0043] In this invention, the base plate 1 is made of high-strength steel to ensure that it can withstand the weight of multiple reciprocating compressor side covers 3.

[0044] Regarding the number of columns of the storage rod 2, in this embodiment, two columns are specifically set. Specifically, one column of storage rod 2 can be set on each of the two sides of the base plate 1, and several columns can be added in the middle according to actual needs.

[0045] The distance between two adjacent storage rods 2 should be slightly greater than the widest part of the reciprocating compressor side cover 3 to ensure that the side cover 3 can be placed smoothly and remain stable.

[0046] This invention arranges the reciprocating compressor side covers 3 sequentially between two adjacent storage rods 2, from one side to the other. This helps maintenance personnel quickly locate each side cover and helps maintain a neat and orderly overall layout.

[0047] For further explanation of this utility model, see [link to relevant documentation]. Figure 3 The base plate 1 is fixed to the main frame 4, and the main frame 4 is fixed to the lifting lug 5.

[0048] The main frame 4 includes a first crossbeam 41, a first longitudinal beam 42, a second crossbeam 43, a second longitudinal beam 44, and a connecting rod 45;

[0049] One end of the first crossbeam 41 is fixed to one end of the first longitudinal beam 42, the other end of the first longitudinal beam 42 is fixed to one end of the second crossbeam 43, and the other end of the second crossbeam 43 is fixed to one end of the second longitudinal beam 44.

[0050] Both ends of the first crossbeam 41 and the second crossbeam 43 are fixed to one end of the connecting rod 45, and the other end of the connecting rod 45 is fixed to the base plate 1.

[0051] This invention enhances the overall rigidity and deformation resistance of the mounting device by incorporating a main frame 4. This not only helps prevent the side cover from shifting or tipping over due to external forces during transport, but also ensures the stability and safety of the device during use.

[0052] The main frame, constructed with robust materials, can withstand repeated loading and unloading operations over a long period without easily being damaged, extending the service life of the installation device. At the same time, excellent design and manufacturing processes reduce maintenance needs and lower operating costs.

[0053] The main frame can be adjusted in size and shape according to specific application scenarios to adapt to different space constraints or special requirements. For example, a more compact frame can be designed for confined spaces; for situations requiring frequent handling, the frame structure can be optimized to reduce weight without sacrificing strength.

[0054] Both ends of the first crossbeam 41 and the second crossbeam 43 are fixed to the lifting lugs 5, which are used to connect to an external handling device.

[0055] In this embodiment, the design of the lifting lug 5 should take into account the connection requirements of the external handling device, and a circular or D-shaped hole design is usually adopted for easy hooking. In this embodiment, a circular lifting lug is selected, and the material of the lifting lug 5 should be high-tensile strength steel to ensure that it will not deform or break during the lifting process.

[0056] Fixed Position: The lifting lugs 5 are fixed at both ends of the first crossbeam 41 and the second crossbeam 43, with one lifting lug 5 at each end of each crossbeam. This allows for a more even distribution of force when using external handling devices such as cranes or overhead cranes for lifting operations, reducing the risk of excessive localized stress.

[0057] As a further explanation of this utility model, Figure 2 and Figure 3 The base plate 1 is equipped with at least one row of storage rods 2, and the specific structure is as follows:

[0058] Each of the storage rods 2 is mounted on a locking device 6, which is located inside a slider 7. The slider 7 is located in and moves along a guide groove 8, which is formed on a base plate 1. The locking device 6 is used to lock the position of the slider 7 in the guide groove 8.

[0059] The slider 7 and the guide groove 8 are in the shape of a dovetail, I-shaped, or T-shaped structure that fits each other.

[0060] This invention enables flexible arrangement of the storage rod 2 on the base plate 1 and ensures its stability and safety during use.

[0061] By flexibly adjusting the position of the storage rod 2, an optimal layout can be achieved for the reciprocating compressor side covers 3 of different sizes and shapes, maximizing the use of the space on the base plate 1. This not only helps to accommodate more side covers 3, but also reduces unnecessary gaps and improves overall storage efficiency.

[0062] Different maintenance or storage scenarios may require different side cover arrangements. The flexible arrangement of the storage rod 2 can quickly respond to these changes, easily handling both the temporary addition of new side covers and the repositioning of existing side covers, thus improving the versatility and flexibility of the device.

[0063] Since the spacing of the storage rod 2 can be precisely adjusted according to actual needs, it can effectively avoid mutual squeezing or collision between the side covers 3 due to being too tight, thus reducing the possibility of physical damage.

[0064] See Figures 3-7 In this embodiment, the locking device 6 includes a first bevel gear 61, a second bevel gear 62, a third bevel gear 63, a first lead screw 64, a second lead screw 65, a first locking head 66, a second locking head 67, and a guide hole 68;

[0065] The slider 7 is hollow inside, and part of the storage rod 2 is disposed inside the slider 7 and connected to the slider 7 bearing. The slider 7 is coaxially fixed with the first bevel gear 61. The first bevel gear 61 meshes with the second bevel gear 62 and the third bevel gear 63. The second bevel gear 62 and the third bevel gear 63 are both installed inside the slider 7 through bearings.

[0066] The second bevel gear 62 is threadedly connected to the first lead screw 64, the first lead screw 64 is fixed to the first locking head 66, the first locking head 66 is disposed in the guide hole 68 and can move along it, the guide hole 68 is opened through both sides of the slider 7;

[0067] The third bevel gear 63 is threadedly connected to the second lead screw 65, the second lead screw 65 is fixed to the second locking head 67, and the second locking head 67 is disposed in the guide hole 68 and can move along it;

[0068] The first locking head 66, the second locking head 67, and the guide hole 68 are rectangular shapes that fit together.

[0069] The non-utility model rotates the storage rod 2, causing the first bevel gear 61 to drive the second bevel gear 62 and the third bevel gear 63 to rotate in opposite directions. Since the second bevel gear 62 and the third bevel gear 63 are bearings inside the slider 7, they can be understood as nuts. Because the first locking head 66 and the second locking head 67 are set in the rectangular guide hole 68, the first locking head 66 and the second locking head 67 do not rotate, thereby driving the first lead screw 64 and the second lead screw 65 to move left and right, which can tightly press against the inner wall of the guide groove 8 to achieve locking. Because the second bevel gear 62 is threadedly connected to the first lead screw 64 and the third bevel gear 63 is threadedly connected to the second lead screw 65, they are self-locking. Therefore, they will not automatically unlock unless the storage rod 2 is rotated in the opposite direction.

[0070] Before adjusting the position of the storage rod 2, the locking device 6 is first released. This can be done by slightly rotating the storage rod 2 in the opposite direction, causing the first locking head 66 and the second locking head 67 to retract from the inner wall of the guide rail 8 into the slider 7.

[0071] In order to make the first lead screw 64 and the second lead screw 65 move in opposite directions, this can be achieved by setting their rotation direction. Setting the rotation direction of the first lead screw 64 and the second lead screw 65 to be opposite will enable them to move in opposite directions.

[0072] After adjustment, rotate the storage rod 2 clockwise again until you hear or feel the locking head contacting the inner wall of the guide rail 8 and locking securely.

[0073] Through the specific implementation steps described above, the position of the storage rod 2 can be flexibly adjusted and stably locked. This design not only simplifies the operation process and improves work efficiency, but also ensures that it will not be accidentally unlocked due to external vibration or other factors during use, thereby enhancing the safety and reliability of the entire device.

[0074] The locking device 6 can also use a miniature linear motor or the like. Those skilled in the art can use any device capable of locking according to actual needs.

[0075] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 Multiple casters 9 are mounted on the base plate 1, and each caster 9 is equipped with a braking device.

[0076] Selection and Arrangement of 9 Universal Wheels

[0077] Material selection: Wear-resistant, pressure-resistant, and high-load-bearing polyurethane or rubber is selected as the wheel surface material for the caster wheel 9. The axle is made of high-strength steel to ensure stability and reliability under long-term use.

[0078] Quantity Determination: Based on the size of the base plate 1 and the expected load, the number of casters 9 is reasonably configured. In this embodiment, one caster 9 is installed at each of the four corners of the base plate 1. If the base plate 1 is large or is expected to bear a heavy load, additional casters 9 can be added in the middle position to distribute the weight and ensure smooth movement.

[0079] Installation of 9 omnidirectional wheels

[0080] Fixing method: The casters 9 are directly fixed to the pre-drilled holes at the bottom of the base plate 1 using bolts. For easy disassembly and maintenance, it is recommended to use bolts with locking nuts. Furthermore, ensure all casters 9 are at the same height to keep the entire assembly level.

[0081] Positioning: The casters 9 should be evenly distributed around the bottom perimeter and center of the base plate 1 to ensure the stability of the device's center of gravity when moving, and to avoid the risk of tilting or tipping over.

[0082] Braking device design

[0083] Type Selection: Each caster wheel 9 is equipped with an independent mechanical foot brake. This brake is simple and intuitive to operate; simply press the pedal for instant braking and release the pedal to release the lock. For applications requiring frequent movement, an electric braking system can also be considered, but the cost is relatively higher.

[0084] Installation location: The brake pedal should be designed in an easily accessible location, such as near the edge of the base plate 1, so that the operator can easily control it with their foot. At the same time, the brake device itself must have good protective measures to prevent foreign objects from entering and affecting normal operation.

[0085] Functional verification: Each braking device must undergo rigorous testing to ensure effective braking under various ground conditions and to prevent accidental unlocking due to vibration or other factors. Regularly inspect the brake system for wear and replace damaged parts promptly to ensure safety performance.

[0086] Through the specific implementation steps described above, the effective configuration of the casters 9 and their braking devices on the base plate 1 was achieved. This design not only improves the mobility and flexibility of the device, but also enhances its stability and safety in different working environments, greatly facilitating the user's daily operation and maintenance management.

[0087] See Figure 4 A lifting ring 10 is fixed on the side cover 3 of the reciprocating compressor, and the lifting ring 10 is connected to the overhead crane through a mother-daughter chain 11.

[0088] The lifting ring 10 should be made of high-strength, corrosion-resistant alloy steel or stainless steel to ensure that it can withstand heavy loads for a long time and is not easily damaged by rust. For applications in special environments, chrome plating or other surface treatments can be considered to enhance corrosion resistance.

[0089] Referring to Figure 4, the lifting ring 10 is welded or bolted to a suitable location on each reciprocating compressor side cover 3. In this embodiment, the lifting ring 10 is located in the middle of the side cover 3 to ensure uniform force distribution during lifting and avoid excessive local stress that could cause deformation or damage.

[0090] The mother-daughter chain 11 consists of two parts—a daughter chain and a mother chain—which are quickly connected and separated by special connectors. One end of the daughter chain is fixed to the lifting ring 10, and the other end is equipped with a standard hook; the mother chain is directly connected to the crane hook.

[0091] Each sub-chain can be equipped with one side cover. Four to eight side covers can be installed at the same time, which greatly improves work efficiency, reduces the time the crane is used repeatedly, and lowers the probability of crane failure.

[0092] Using this method for installing and reinstalling the side cover of a reciprocating compressor is labor-saving and accurate. This special tool is designed based on actual repair work and is reasonable, simple and quick to use. It is applied to the installation of side covers for large reciprocating compressors, which greatly improves work efficiency, reducing the number of people required from 6 to 2 and shortening the time from 4 hours to 0.5 hours.
