Description

Technical Field

[0001] This application relates to the field of gas compressor technology, and more particularly to a gas compressor that is easy to maintain. Background Technology

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is commonly used to provide gas power for pneumatic tools and is also frequently used in industries such as petrochemicals, drilling, and metallurgy to pressurize and transport media such as oxygen, hydrogen, ammonia, natural gas, coke oven gas, and inert gases.

[0003] Existing gas compressors typically use bolts to weld the twin-screw compressor cylinder and drive motor to the pressure tank, or use mounting plates and bolts to fix the twin-screw compressor cylinder and drive motor. Welding methods require overall maintenance during repairs, making it inconvenient to install and disassemble the various components. Bolted methods, on the other hand, are prone to rust and corrosion due to the exposed bolts during long-term use, leading to bolt damage and making disassembly difficult. Therefore, they are inconvenient for users. Utility Model Content

[0004] This application provides a gas compressor that is easy to maintain, in order to solve the problems of existing gas compressors that generally fix the twin-screw compressor cylinder and drive motor to the pressure tank by bolts or by mounting plates and bolts. Welding methods require overall maintenance during the maintenance process, which is not convenient for installing and disassembling the various components. On the other hand, bolt-fixed methods are prone to rust and corrosion due to the bolts being exposed to the outside environment during long-term use, which can cause bolt damage and make disassembly inconvenient.

[0005] This application provides a gas compressor that is easy to maintain, including a mounting plate body. Two sets of limiting brackets are mounted on the top of the mounting plate body. Each of the two sets of limiting brackets has a fixing groove on one side. A positioning bolt is threaded into the fixing groove. A mounting slide plate is slidably connected between the two sets of limiting brackets. A twin-screw compressor cylinder is mounted on the top of the mounting slide plate. A drive motor is mounted on one end of the twin-screw compressor cylinder. Movable sliders are mounted on both ends of the mounting slide plate. A limiting groove is formed on the top of the limiting bracket. A positioning rod is mounted on the top of the movable slider. A shrink sleeve is sleeved on the outer wall of the positioning rod. A return spring is installed inside the shrink sleeve. A positioning slot is formed inside the limiting groove.

[0006] Preferably, a set of casters is installed at the bottom of the mounting plate body, and a handle is installed on one side of the mounting plate body.

[0007] Preferably, a pressure tank is provided at the top of the mounting plate body, an air inlet is provided at one end of the pressure tank, and a valve is provided at the top of the air inlet.

[0008] Preferably, a pressure gauge is installed at the end of the pressure tank away from the air inlet.

[0009] Preferably, an exhaust pipe is installed at the end of the pressure tank near the pressure gauge.

[0010] Preferably, a fixing plate is installed at the bottom end of the return spring.

[0011] Preferably, the limiting slide groove is further provided with a movable groove inside.

[0012] Beneficial effects:

[0013] Considering that existing gas compressors generally fix the twin-screw compressor cylinder and drive motor to the pressure tank by bolts or by mounting plates and bolts, the welding method requires overall maintenance during the maintenance process, which is not convenient for installing and disassembling the various components. On the other hand, the bolt fixing method is prone to rust and corrosion due to the bolts being exposed to the outside during long-term use, which causes bolt damage and makes disassembly inconvenient.

[0014] By placing the pressure tank at the top of the mounting plate, two sets of limiting brackets are installed at the top of the mounting plate using positioning bolts. These two sets of limiting brackets limit and protect the pressure tank. When maintenance is required, the pressure tank can be accessed simply by removing the two sets of limiting brackets. The twin-screw compressor and drive motor are slidably connected between the two sets of limiting brackets via a mounting slide plate. When maintenance is needed on the twin-screw compressor and drive motor, the positioning rod can be pulled upwards to disengage its bottom from the positioning slot. Then, the mounting slide plate can be pulled laterally to allow the movable slider to slide in the limiting groove, facilitating the removal of the mounting slide plate from the two sets of limiting brackets. This allows for easy disassembly and maintenance of the twin-screw compressor and drive motor. During installation, simply insert the movable slider into the limiting groove, then push the mounting slide plate until the positioning rod is inserted into the positioning slot under the action of the return spring.

[0032] This utility model provides, for example Figure 1-7 The gas compressor shown is easy to maintain and includes a mounting plate body 1. Two sets of limiting brackets 11 are mounted on the top of the mounting plate body 1. Each of the two sets of limiting brackets 11 has a fixing groove 12 on one side. The fixing groove 12 is threaded with a positioning bolt 13. A mounting slide plate 14 is slidably connected between the two sets of limiting brackets 11. A twin-screw compression cylinder 9 is mounted on the top of the mounting slide plate 14. A drive motor 10 is mounted on one end of the twin-screw compression cylinder 9. Movable sliders 15 are mounted on both ends of the mounting slide plate 14. A limiting groove 16 is opened on the top of the limiting bracket 11. A positioning rod 17 is mounted on the top of the movable slider 15. A shrink sleeve 18 is sleeved on the outer wall of the positioning rod 17. A return spring 19 is installed inside the shrink sleeve 18. A positioning slot 21 is opened inside the limiting groove 16.

[0033] In this system, the pressure tank 4 is placed at the top of the mounting plate body 1, and two sets of limiting brackets 11 are installed at the top of the mounting plate body 1 using positioning bolts 13. The two sets of limiting brackets 11 limit and protect the pressure tank 4. When maintenance is required, the pressure tank 4 can be accessed simply by removing the two sets of limiting brackets 11. Simultaneously, the twin-screw compressor 9 and the drive motor 10 are slidably connected between the two sets of limiting brackets 11 via a mounting slide plate 14. When maintenance is required on the twin-screw compressor 9 and the drive motor 10, [the following steps can be taken]. By pulling the positioning rod 17 upward, the bottom end of the positioning rod 17 is disengaged from the positioning slot 21. At this time, the installation slide plate 14 can be pulled horizontally, so that the movable slider 15 will slide in the limiting slide groove 16. This makes it easy to pull the installation slide plate 14 out from the two sets of limiting frames 11, which is convenient for users to disassemble and repair the twin screw compressor cylinder 9 and the drive motor 10. During installation, simply insert the movable slider 15 into the limiting slide groove 16, and then push the installation slide plate 14 until the positioning rod 17 is inserted into the positioning slot 21 under the action of the return spring 19 to complete the installation.

[0034] The bottom of the mounting plate body 1 is equipped with a set of casters 2, and a handle 3 is installed on one side of the mounting plate body 1.

[0035] The device is equipped with four sets of casters 2 at the bottom of the mounting plate body 1. Users can push the device by holding the handle 3. With the help of the casters 2, users can easily move the device to a suitable location.

[0036] A pressure tank 4 is provided at the top of the mounting plate body 1. An air inlet 5 is installed at one end of the pressure tank 4, and a valve 6 is provided at the top of the air inlet 5.

[0037] Gas can be introduced into the pressure tank 4 through the air inlet 5, and the gas input can be controlled by the valve 6.

[0038] A pressure gauge 7 is installed at the end of the pressure tank 4 away from the air inlet 5.

[0039] When gas is being introduced into pressure tank 4, pressure gauge 7 can be observed to stop the gas supply to pressure tank 4 at any time.

[0040] An exhaust pipe 8 is installed at the end of the pressure tank 4 near the pressure gauge 7.

[0041] The gas inside the pressure tank 4 can be discharged through the exhaust pipe 8.

[0042] A fixing plate 20 is installed at the bottom end of the return spring 19.

[0043] The elasticity of the return spring 19 allows the positioning rod 17 to automatically spring into the positioning slot 21 when it passes through the positioning slot 21.

[0044] The limiting slide 16 also has an active groove 22 inside.

[0045] The movable groove 22 is provided inside the limiting groove 16, allowing the shrink sleeve 18 to slide inside.

[0046] Working principle: This easy-to-maintain gas compressor is used by placing the pressure tank 4 on the top of the mounting plate body 1, and installing two sets of limit brackets 11 on the top of the mounting plate body 1 using positioning bolts 13. The two sets of limit brackets 11 limit and protect the pressure tank 4. When maintenance is required, the pressure tank 4 can be maintained simply by removing the two sets of limit brackets 11.

[0047] Meanwhile, the twin-screw compressor 9 and the drive motor 10 are slidably connected between two sets of limit frames 11 via the mounting plate 14. When maintenance is required on the twin-screw compressor 9 and the drive motor 10, the positioning rod 17 can be pulled upwards to disengage the bottom end of the positioning rod 17 from the positioning slot 21. At this time, the mounting plate 14 can be pulled horizontally to allow the movable slider 15 to slide in the limit groove 16, thus facilitating the removal of the mounting plate 14 from the two sets of limit frames 11. This makes it convenient for users to disassemble and maintain the twin-screw compressor 9 and the drive motor 10. During installation, simply insert the movable slider 15 into the limit groove 16, and then push the mounting plate 14 until the positioning rod 17 is inserted into the positioning slot 21 under the action of the return spring 19 to complete the installation.

[0048] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
