Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof motors, in particular to an explosion-proof motor with connection reinforcement and anti-shake. Background Art

[0002] An explosion-proof motor is a motor that can be used in flammable and explosive places. It does not generate sparks during operation. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery. For example, the patent document with application number CN201811411378.5 discloses an adjustable shock-absorbing motor. After the motor generates vibration, it is transmitted to the hydraulic oil vibration. The hydraulic oil is transmitted to the shock-absorbing rod through the piston. The shock-absorbing rod transmits the vibration to the lower surface of the base, so that the position of the motor can be adjusted.

[0003] However, in similar solutions mentioned above, during long-term operation of the motor, the connecting bolts and the front cover become loose due to vibration, resulting in a loose connection after long-term use. In addition, when the motor is running, the output end of the motor vibrates, causing looseness between the motor and the output device after long-term use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an explosion-proof motor with connection reinforcement and anti-vibration is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an explosion-proof motor with a reinforced connection to prevent shaking, which solves the similar scheme proposed in the above background technology. The connection of the explosion-proof motor is a rigid connection. Since the temperature of the motor increases during operation, the bolts are deformed and the threaded holes are enlarged. After long-term use, the connection is not firm. In addition, when the motor is running, the output end of the motor shakes, causing the connection between the motor and the device to loosen after long-term use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof motor with connection reinforcement and anti-shake, comprising a shell, a connecting assembly and an anti-shake assembly, a front end cover is arranged on the right side of the shell, and the connecting assembly is located on the inner side of the shell, and the connecting assembly comprises a connecting ring, a long bolt, a short bolt, a fixing plate and a butterfly spring, the inner side of the front end cover is fitted with the connecting ring, and the outer side of the connecting ring is penetrated by the long bolt, and the right side of the long bolt is penetrated by the short bolt, the fixing plate is arranged on the inner side of the connecting ring, and the outer sides of the long bolt and the short bolt are both clamped with the butterfly spring, the anti-shake assembly is located below the shell, and the anti-shake assembly comprises a supporting spring, a connecting rod, a sliding rod and a lateral shock absorber, and two groups of the supporting springs are arranged on the inner side of the shell, the inner side of the supporting spring is hinged with the connecting rod, and the lower end of the connecting rod is hinged with the lateral shock absorber, and the inner side of the lateral shock absorber is slidably connected with the sliding rod.

[0007] Furthermore, the long bolt passes through the connecting ring and the fixing plate, and a rubber pad is provided between the connecting ring and the front end cover.

[0008] Furthermore, the long bolts and the short bolts are provided in a plurality of groups, and the cross section of the connecting ring is L-shaped.

[0009] Furthermore, a body is arranged inside the shell, an output shaft is connected to the right side of the body, and a support base is fixed below the shell.

[0010] Furthermore, the sliding rod and the lateral shock absorber are both located below the supporting base, and the connecting rod is hinged with the lateral shock absorber and the output shaft to form a rotating structure.

[0011] Furthermore, the support springs and the connecting rods are symmetrically arranged in two groups about the vertical center line of the lateral shock absorber.

[0012] The utility model provides an explosion-proof motor with a connection reinforcement and anti-shake, which has the following beneficial effects:

[0013] It can prevent the connection bolts and the front cover from loosening due to vibration after the motor has been running for a long time, and prevent the connection from being loose after long-term use. In addition, when the motor is running, it can prevent the output end of the motor from shaking, and prevent the connection between the motor and the device from loosening after long-term use. The specific contents are as follows:

[0014] During installation, the connecting ring and the fixing plate are installed on the inner side of the outer shell and fixed with long bolts. Since a butterfly spring is arranged on the outer side of the long bolt, the butterfly spring can elastically extend to compensate for the bolt to avoid loose connection after vibration. When the output shaft shakes up and down, it drives the supporting spring to move downward and drives the connecting rod to rotate inward, thereby compressing and stretching the lateral shock absorber, thereby avoiding excessive shaking of the output shaft.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, an explosion-proof motor with connection reinforcement and anti-shake includes a shell 1, a connection component 3 and an anti-shake component 7. A front cover 2 is arranged on the right side of the shell 1, and the connection component 3 is located on the inner side of the shell 1, and the connection component 3 includes a connection ring 301, a long bolt 302, a short bolt 303, a fixing plate 304 and a butterfly spring 305. The inner side of the front cover 2 is fitted with a connection ring 301, which has a simple structure and is easy to install. The outer side of the connection ring 301 is penetrated by a long bolt 302, and the right side of the long bolt 302 is penetrated by a short bolt 303. Because the long bolt 302 and the short bolt 303 are both provided in several groups, and the cross-section of the connection ring 301 is L-shaped, it is convenient to connect and install the front cover 2. The front end cover 2 can be fixed by installing bolts on the outer side of the connecting ring 301. The long bolt 302 penetrates the connecting ring 301 and the fixing plate 304. A rubber pad 311 is provided between the connecting ring 301 and the front end cover 2 to reduce the friction between the connecting parts when the motor is running. A fixing plate 304 is provided on the inner side of the connecting ring 301 to improve the stability of the connection. The outer sides of the long bolt 302 and the short bolt 303 are both engaged with butterfly springs 305 to buffer and absorb vibration, thereby preventing the connection bolts and the front end cover 2 from loosening due to vibration after the motor has been running for a long time, preventing the connection from being loose after long-term use, improving the stability of the connection, and improving the support of the connection.

[0022] An organic body 4 is arranged on the inner side of the shell 1, and an output shaft 5 and a motor top removal device are connected to the right side of the organic body 4, and a support base 6 is fixed at the bottom of the shell 1 for supporting the motor and improving the stability of the motor. An anti-shake component 7 is located at the bottom of the shell 1, and the anti-shake component 7 includes a support spring 701, a connecting rod 702, a sliding rod 703 and a lateral shock absorber 704, and two groups of support springs 701 are arranged on the inner side of the shell 1 to support the output shaft 5, a connecting rod 702 is hinged on the inner side of the support spring 701, and a lateral shock absorber 704 is hinged on the lower end of the connecting rod 702 to absorb the jitter of the output end 5 during operation to avoid the motor and the input device from being jittered after long-term use. The connection between the two ends of the motor 701 and the connecting rod 702 is loose, and two groups of support springs 701 and connecting rods 702 are symmetrically arranged about the vertical center line of the lateral shock absorber 704, so as to improve the stability of the output shaft 5, and the inner side of the lateral shock absorber 704 is slidably connected with a sliding rod 703, and the sliding rod 703 and the lateral shock absorber 704 are both located below the support base 6, so as to reduce the occupied space inside the motor, and the connecting rod 702 is hinged with the lateral shock absorber 704 and the output shaft 5 to form a rotating structure. When the output shaft 5 shakes up and down, the support springs 701 and the lateral shock absorber 704 can support the output shaft through the connecting rod 702, thereby improving the stability of the rotation of the output shaft 5 and improving the stability of the motor during operation.

[0023] In summary, when this type of explosion-proof motor with connection reinforcement and anti-shake is used, first, during installation, the connecting ring 301 is installed on the inner side of the shell 1, and the long bolt 302 is inserted into the through hole on the connecting ring 301, the butterfly spring 304 is installed on the outer side of the long bolt 302, and the through hole on the fixing plate 304 is aligned with the through hole on the connecting ring 301 and installed, and then the front end cover 2 is buckled on the right side of the shell 1, and the butterfly spring 305 and the short bolt 303 are fixed to the outer side of the front end cover 2. The butterfly spring 305 can be used for buffering and vibration absorption, and the fixing plate 304 can further strengthen the firmness of the connection. Start the motor, the motor drives the output shaft 5 to rotate, and the output shaft 5 shakes up and down when rotating, thereby driving the support spring 701 to compress and extend, and driving the two sets of connecting rods 702 to rotate along the hinge, and compressing and stretching the lateral shock absorber 704 inward, thereby reducing the shaking amplitude of the output shaft 5.
