Description

Technical Field

[0001] The present application relates to the field of air compressors, and in particular, to an engine mounting structure for an air compressor. Background Art

[0002] An air compressor is a device used to compress gas and can provide air kinetic energy for pneumatic equipment. An air compressor compresses air and needs to use an engine to provide it with kinetic energy, thereby continuously compressing the air into compressed gas. The engine is large in size and weight, and it will vibrate when it is operating, so a specific mounting bracket is required to stably install it inside the air compressor to ensure the smooth operation of the equipment.

[0003] In the prior art, bolts and nuts are usually used to fix the engine's legs on the mounting bracket. However, since the engine generates vibrations when it is running, long-term vibrations can easily cause the screws and nuts to loosen. The air compressor contains high-temperature and high-pressure gas, and a loose engine may cause a safety hazard.

[0004] Therefore, it is necessary to design an engine mounting structure for an air compressor with a tighter connection, which can avoid the problem of bolt loosening caused by long-term vibration of the engine. Utility Model Content

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide an engine mounting structure for an air compressor, including:

[0007] A support plate, the top surface of which forms two oppositely disposed support surfaces;

[0008] There are two mounting plates, which are fixedly mounted on two supporting surfaces respectively, and two mounting holes are formed on the mounting plates;

[0009] Two reinforcement plates are provided, and the two reinforcement plates are respectively fixedly arranged on the bottom surfaces of the two mounting plates;

[0010] A fastening bolt is inserted into the mounting hole;

[0011] Clamping assembly, the clamping assembly comprises:

[0012] A fastening seat, with two ends respectively fixedly mounted on the support plate and the reinforcement plate;

[0013] Two clamping blocks are provided, and the two clamping blocks are arranged opposite to each other along the extension direction of the fastening seat and can move relative to the fastening seat;

[0014] A driving member is arranged on the fastening seat to drive the two clamping blocks to move;

[0015] A clamping groove is formed on the fastening bolt, and the two clamping blocks are respectively engaged with the clamping grooves on the two fastening bolts after moving.

[0016] During the installation process, the engine support foot is placed on the mounting plate, and the fastening bolt is inserted from the threaded hole of the engine support foot into the mounting hole on the mounting plate; since a clamping assembly is provided, the clamping assembly can limit the fastening bolt in the insertion direction, and the two clamping blocks are driven by the driving member to move relative to each other. After the clamping blocks move, they engage with the clamping grooves on the fastening bolt to prevent the vibration generated during the operation of the engine from causing the connection between the engine support foot and the mounting plate to become loose.

[0017] Furthermore, the driving member is a double-ended screw rotatably arranged on the fastening seat, and the threads at both ends of the double-ended screw are in opposite directions;

[0018] The two clamping blocks are threadedly connected with the double-headed lead screw.

[0019] Furthermore, the surface portion of the fastening seat is concave to form a moving groove, a fixing block is fixedly arranged in the middle of the moving groove, and the double-headed screw is rotatably arranged on the fixing block;

[0020] The two clamping blocks are respectively arranged on both sides of the fixed block, and the side walls of the clamping blocks are fitted with the inner walls of the movable groove.

[0021] Furthermore, a rotating block is provided on one side of the reinforcing plate, and one end of the double-headed screw rod close to the reinforcing plate is inserted through the reinforcing plate and fixedly connected to the rotating block.

[0022] Further, the top surface of the bottom plate of the air compressor is set as the reference plane L;

[0023] After being extended, the top surface of the mounting plate forms an angle α with the reference plane L, and the value range of α is 120°-170°.

[0024] Furthermore, an internal thread is formed in the mounting hole, and an external thread corresponding to the internal thread of the mounting hole is formed on the fastening bolt.

[0025] Furthermore, a stabilizing plate is fixedly arranged in the middle of the supporting plate.

[0026] The beneficial effects of this application are:

[0027] 1. After the clamping block moves, it can engage with the clamping groove on the fastening bolt, limiting the fastening bolt in the insertion direction, so that the connection between the engine support foot and the mounting plate is tighter;

[0028] 2. The top surface of the mounting plate is extended to form an angle with the reference plane L. When the engine vibrates, the mounting plate can reduce the force of the engine on the fastening bolt and slow down the loss of the fastening bolt;

[0029] 3. An internal thread is formed in the mounting hole, and an external thread is formed on the fastening bolt. The fastening bolt can be screwed into the mounting hole by means of a threaded connection, thereby further strengthening the connection between the engine support foot and the mounting plate.

[0045] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0046] An engine mounting structure for an air compressor comprises: a support plate 1, a mounting plate 2, a reinforcement plate 3, and a fastening bolt 4;

[0047] Specifically, the support plate 1 is fixedly mounted on the bottom plate 5 of the air compressor, and the top surface of the support plate 1 forms two support surfaces 8 which are arranged opposite to each other along the length direction of the support plate 1, and the two mounting plates 2 are respectively fixedly mounted on the two support surfaces 8, and the two reinforcing plates 3 are respectively fixedly mounted on the bottom surfaces of the two mounting plates 2 to further support the mounting plate 2; a stabilizing plate 9 is fixedly mounted in the middle of the support plate 1 to increase the stability of the support plate 1; the support foot 7 of the engine 6 is provided with two threaded holes for mounting, and the mounting plate 2 is provided with mounting holes 10 corresponding to the threaded holes on the support foot 7 of the engine 6, and an internal thread is formed in the mounting hole 10, and an external thread corresponding to the internal thread of the mounting hole 10 is formed on the fastening bolt 4, and the support foot 7 of the engine 6 and the mounting plate 2 can be connected by screwing the fastening bolt 4 from the threaded hole of the support foot 7 of the engine 6 into the mounting hole 10;

[0048] The top surface of the base plate 5 of the air compressor is set as the reference plane L11, and the top surface of the mounting plate 2 is extended to form an angle α12 with the reference plane L11, and the value of α12 is 145°; the inclination angle of the mounting plate 2 corresponds to the inclination angle of the support foot 7 of the engine 6. The inclined setting of the mounting plate 2 can reduce the force acting on the fastening bolt 4 when the engine 6 vibrates, thereby reducing the loss of the fastening bolt 4.

[0049] The engine mounting structure for the air compressor further includes a clamping assembly 13, which can limit the position of the fastening bolt 4 along the insertion direction of the fastening bolt 4, so as to prevent the vibration generated when the engine 6 is in operation from causing the fastening bolt 4 and the connection between the support leg 7 of the engine 6 and the mounting plate 2 to be separated, resulting in an unstable installation of the engine 6. Since the air compressor contains high-temperature and high-pressure gas, the engine 6 may cause a safety accident after becoming unstable.

[0050] Specifically, the clamping assembly 13 includes a fastening seat 14, a clamping block 15, and a driving member 16; more specifically, connecting plates 17 are fixedly arranged at both ends of the fastening seat 14, and the two connecting plates 17 are respectively fixedly installed on the reinforcing plate 3 and the supporting plate 1 by bolts; the surface portion of the fastening seat 14 is concave to form a movable groove 18, and the extending direction of the movable groove 18 is the same as the direction of the center connecting line of the two mounting holes 10 on the same mounting plate 2, and a fixed block 19 is fixedly arranged in the middle of the movable groove 18, and the driving member 16 is a double-headed screw 20, and the middle part of the double-headed screw 20 is rotatably arranged on the fixed block 19, and the two clamping blocks 15 are relatively arranged on the double-headed screw 20 and are located on both sides of the fixed block 19, and the side walls of the clamping blocks 15 are in contact with the inner wall of the movable groove 18, and the clamping blocks 15 are threadedly connected to the double-headed screw 20, and the thread directions of the threads on both sides of the double-headed screw 20 are opposite;

[0051] A rotating block 21 is provided on one side of the reinforcing plate 3. One end of the double-headed screw 20 close to the reinforcing plate 3 is inserted through the reinforcing plate 3 and fixedly connected to the rotating block 21. The double-headed screw 20 can be driven to rotate by twisting the rotating block 21. When the double-headed screw 20 rotates, the side wall of the clamping block 15 fits with the inner wall of the moving groove 18, and the clamping block 15 is limited in the rotation direction, and the clamping block 15 moves relatively along the double-headed screw 20.

[0052] A clamping groove 22 is formed on the fastening bolt 4. After the two clamping blocks 15 are moved, they can be respectively clamped into the clamping grooves 22 on the two fastening bolts 4, so as to limit the fastening bolt 4 and avoid the problem of loose installation of the engine 6 caused by the fastening bolt 4 being disconnected from the support leg 7 and the mounting plate 2 of the engine 6 due to the vibration of the engine 6;

[0053] The specific working principle is as follows: place the support foot 7 of the engine 6 on the mounting plate 2, screw the fastening bolt 4 into the threaded hole of the support foot 7 of the engine 6 and the mounting hole 10 of the mounting plate 2 to preliminarily install the engine 6; rotate the rotating block 21 to drive the double-headed screw 20 to rotate, and the two clamping blocks 15 move relative to each other and are respectively clamped into the clamping grooves 22 on the two fastening bolts 4, so that the connection between the engine support foot 7 and the mounting plate 2 is tighter.

[0054] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
