[0002] An explosion-proof screw compressor is a screw-type air compressor or other screw-type fluid conveying equipment with explosion-proof function. In places where flammable and explosive dust or gases exist, such as flour mills, oil depots, paint factories, and coal mines, explosion-proof screw compressors can play an important role in providing safe and reliable compressed air or other fluid conveyance for production equipment.

[0003] Since the base of the screw compressor is mostly an integral structure with the screw compressor itself and is fixed by bolts, the internal mechanical movement, airflow pulsation and equipment load changes during operation will generate vibration. Prolonged vibration will cause the bolts to loosen, which will affect the service life and operational stability of the equipment, and may also cause safety hazards in explosion-proof environments.

[0004] Therefore, it is necessary to provide a new explosion-proof screw compressor to solve the above-mentioned technical problems. Utility Model Content

[0016] Compared with related technologies, the explosion-proof screw compressor provided by this utility model has the following advantages:

[0017] 1. By setting shock absorbers and shock-absorbing springs in the support assembly, this utility model can buffer and dampen the vibration generated when the explosion-proof screw compressor is working, thereby reducing the noise generated by the vibration transmitted to the base plate.

[0018] 2. By setting adjustment rods a and b in the support assembly, this utility model allows for stepless horizontal adjustment of the explosion-proof screw compressor's outlet to an external pipeline after the base plate is fixed to the ground during installation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 5 The present invention provides an explosion-proof screw compressor, which includes an explosion-proof screw compressor 1.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 5 The explosion-proof screw compressor 1 is equipped with a cylinder 11, and a mounting plate 12 is located at the bottom of the cylinder 11. A support assembly 2 is located at the bottom of the mounting plate 12, and the support assembly 2 includes a base plate 21. A support plate 22 is movably connected to the top of the base plate 21, and a top plate 23 is movably connected to the top of the support plate 22. Multiple evenly distributed shock absorbers 24 are located on the top of the top plate 23. The top of the shock absorbers 24 is connected to the bottom of the mounting plate 12, and shock-absorbing springs 241 are provided on the outside of the shock absorbers 24. An adjusting rod a is mounted on the top of the base plate 21. 212, The adjusting rod a212 is provided with a threaded adapter plate a213, the top of the adapter plate a213 is fixedly connected to the bottom of the support plate 22, and the base plate 21 is provided with a self-locking motor that drives the adjusting rod a212; The top of the support plate 22 is provided with an adjusting rod b222, the adjusting rod b222 is provided with a threaded adapter plate b223, the top of the adapter plate b223 is fixedly connected to the bottom of the top plate 23, and the top of the support plate 22 is provided with a self-locking motor that drives the adjusting rod b222.

[0030] It should be noted that during installation, after the base plate 21 is fixed to the ground, when connecting the outlet of the explosion-proof screw compressor 1 to the external pipeline, the adjusting rods a212 and b222 can be operated by controlling the self-locking motor. The operating adjusting rods a212 and b222 will drive the top support plate 22 and top plate 23 to move through the corresponding adapter plates a213 and b223, thereby enabling stepless horizontal adjustment of the explosion-proof screw compressor 1. At the same time, the cylinder 11 can be controlled to operate for vertical adjustment, thus making the position adjustment of this device more flexible and accurate.

[0031] The shock absorber 24 and the shock-absorbing spring 241 in the support assembly 2 can buffer and dampen the vibration generated when the explosion-proof screw compressor 1 is working, thereby reducing the noise generated by the vibration transmitted to the base plate 21 and further improving the quietness effect.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 5The top of the base plate 21 is provided with multiple sets of fixing components 3. The fixing components 3 include fixing bolts 31, which are installed on the base plate 21 by a threaded structure. A support cylinder 4 is fixedly connected to the outside of the fixing bolts 31 on the top of the base plate 21. The top of the fixing bolts 31 is provided with a mounting groove 311, and the side wall of the fixing bolts 31 is provided with symmetrically distributed grooves 312. The inside of the grooves 312 is provided with guide holes 313. A slidingly connected limiting bracket 321 is inserted into the guide holes 313. The two ends of the limiting bracket 321 are respectively located in the fixed mounting grooves 311. Within the groove 312, and on one side of the limiting frame 321 located inside the groove 312, there is a fixedly connected driving plate 32, and the side wall specification of the driving plate 32 is smaller than the inner wall specification of the groove 312. One end of the limiting frame 321 located inside the mounting groove 311 is provided with a compression spring 33, and the end of the compression spring 33 is provided with a fixedly connected mounting plate 331, and the mounting plate 331 is fixedly connected to the inner wall of the mounting groove 311. A limiting hole 41 is opened inside the support cylinder 4, and the inner wall of the limiting hole 41 abuts against and slides with the outer wall of the limiting frame 321 located on one side of the groove 312.

[0033] It should be noted that, through the setting of compression spring 33 and limit bracket 321, after the installation of fixing bolt 31 is completed and the external socket wrench is removed, compression spring 33 will drive limit bracket 321 through its own force, so that limit bracket 321 can be inserted into the limit hole 41 inside the external support cylinder 4. Thus, the fixing bolt 31 can be limited, thereby avoiding the noise caused by vibration during use, which would result in the fixing bolt 31 loosening and the base plate 21 hitting the ground. This can help improve the stability and quietness of the device during use.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 5 The bottom plate 21 is provided with a guide frame a211 at the top, and a sliding piece a224 is inserted inside the guide frame a211. The top of the sliding piece a224 is fixedly connected to the bottom of the support plate 22. The support plate 22 is provided with a guide frame b221 at the top, and a sliding piece b231 is inserted inside the guide frame b221. The top of the sliding piece b231 is fixedly connected to the bottom of the top plate 23. The adjusting rods a212 and b222 are staggered.

[0035] It should be noted that: through the setting of guide frame a211, sliding plate a224, guide frame b221 and sliding plate b231, when the self-locking motor outside the corresponding adjusting rod a212 and adjusting rod b222 works and the position of explosion-proof screw compressor 1 is adjusted, sliding plate a224 and sliding plate b231 will slide inside the corresponding guide frame a211 and guide frame b221, thereby guiding the movement of support plate 22 and top plate 23 during adjustment.

[0036] The working principle of the explosion-proof screw compressor provided by this utility model is as follows:

[0037] When installing this device, first move the device to the desired position, then hold the drive plate 32 in the fixing component 3 and move the drive plate 32 into the groove 312 on the side wall of the fixing bolt 31. During this process, the moving drive plate 32 will drive the limiting frame 321 to move synchronously, so that the limiting frame 321 can be moved out of the limiting hole 41 in the external support cylinder 4. Then, the socket wrench can be placed on the fixing bolt 31 to tighten the fixing bolt 31, so that the base plate 21 can be fixedly connected to the ground.

[0038] After the base plate 21 is fixed, the adjusting rods a212 and b222 can be rotated. The rotating adjusting rod a212 will drive the adapter plate a213 and its top support plate 22 to move synchronously through the threaded structure. The rotating adjusting rod b222 will drive the adapter plate b223 and its top plate 23 to move synchronously through the threaded structure. This will drive the explosion-proof screw compressor 1 at the top to make stepless horizontal adjustment, thereby achieving precise adjustment of the outlet position of the explosion-proof screw compressor 1, so that the outlet of the explosion-proof screw compressor 1 can be more accurately aligned and connected with the external pipeline.

[0039] After the installation of the device is completed, when the explosion-proof screw compressor 1 is operating, the shock absorber 24 and shock-absorbing spring 241 on the top of the support assembly 2 can buffer and dampen the vibration generated by the explosion-proof screw compressor 1 during operation, thereby reducing the noise generated by the vibration transmitted to the base plate 21. At the same time, through the setting of the compression spring 33 in the fixing assembly 3, after the fixing bolt 31 is installed and the external socket wrench is removed, the compression spring 33 will drive the limit frame 321 through its own force, so that the limit frame 321 can be inserted into the limit hole 41 inside the external support cylinder 4. Thus, the fixing bolt 31 can be limited, thereby avoiding the noise generated by the base plate 21 hitting the ground due to vibration during use. This can help improve the stability and quietness of the device during use.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
