Description

Technical Field

[0001] This utility model relates to the field of mining electrical equipment, and in particular to a removable mounting base for a mining high-voltage soft starter. Background Technology

[0002] Mining soft starters are key control units for underground mining equipment, enabling smooth starting, current limiting control, and protection functions for three-phase asynchronous motors. They are suitable for hazardous environments such as high-gas and coal dust environments. Mining soft starters are typically installed inside explosion-proof enclosures, which often have a front-opening design. Installing the soft starter within these enclosures requires a mounting bracket, which serves as the connection between the soft starter and the enclosure. Existing mounting brackets are generally fixed, requiring operators to penetrate deep into the enclosure for installation, which is inconvenient. Therefore, developing a removable, easy-to-install mounting base for mining high-voltage soft starters is essential. Summary of the Invention

[0003] The purpose of this utility model is to provide a removable mounting base for a high-voltage soft starter used in mining, which has the advantages of being easy for workers to install and improving convenience.

[0004] The technical solution adopted is as follows:

[0005] A removable mounting base for a high-voltage soft starter used in mining is installed inside an explosion-proof housing. It includes a vertical plate, with horizontally arranged support rods on both sides of the lower end of the vertical plate. A mounting plate is slidably arranged between the two support rods. The end of the mounting plate is provided with a limiting mechanism corresponding to the support rod. A turntable is rotatably arranged at the upper end of the mounting plate. A support shaft is vertically arranged on the turntable and rotatably connected to the mounting plate. A positioning mechanism corresponding to the support shaft is provided at the lower end of the mounting plate.

[0006] Preferably, the limiting mechanism includes a horizontally extending double-headed telescopic rod, which is perpendicular to the support rod, and the inner side of the end of the support rod is provided with a limiting hole corresponding to the double-headed telescopic rod.

[0007] Preferably, the positioning mechanism includes a spring telescopic rod and an external gear ring. The external gear ring is coaxially fixed on the outside of the support shaft. The spring telescopic rod extends radially along the external gear ring. The spring telescopic rod includes an outer tube, in which a spring is installed. An inner shaft is inserted into the inner side of the spring. Both ends of the inner shaft extend to the outside of the outer tube. Both ends of the spring are fixedly connected to the outer tube and the inner shaft, respectively. A limit plate is provided on the side of the inner shaft near the external gear ring.

[0008] Preferably, the spring telescopic rod extends to the front end of the mounting plate and is parallel to the support rod.

[0009] Preferably, a protective cover is provided on the outer side of the external gear ring, and the protective cover has a notch corresponding to the spring telescopic rod.

[0010] Preferably, the vertical plate is horizontally provided with two damping rods parallel to the support rod, and the free ends of the damping rods are fixedly connected to the mounting plate.

[0011] Compared to existing technologies, the advantages are:

[0012] In this invention, when installing a high-voltage soft starter, the operating limit mechanism releases the limit between the mounting plate and the support rod, allowing the mounting plate to be pulled out, facilitating the installation of the high-voltage soft starter on the upper end of the turntable. During cable connection, to facilitate the connection of cables located at the rear end of the high-voltage soft starter, the positioning mechanism's restriction on the support shaft is released, and the turntable is rotated to move the rear side of the high-voltage soft starter to the front or side, facilitating cable connection. Compared to existing fixed mounting brackets, this invention is more convenient for installation and maintenance. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:

[0019] Example 1: A removable mining high-voltage soft starter mounting base is installed inside an explosion-proof housing 1. It includes a vertical plate 2, which is fixedly connected to the explosion-proof housing 1 by bolts. Support rods 3 are horizontally arranged on both sides of the lower end of the vertical plate 2. The support rods 3 are perpendicular to the plane of the vertical plate 2. A mounting plate 4 is slidably arranged between the two support rods 3. The mounting plate 4 has two through holes and slides in the front-back direction.

[0020] The end of the mounting plate 4 is provided with a limiting mechanism corresponding to the support rod 3. The limiting mechanism restricts the position of the mounting plate 4 to prevent the mounting plate 4 from sliding on the support rod 3 under the action of external force, so as to stabilize the installation position of the mining soft starter 6. The upper end of the mounting plate 4 is provided with a turntable 9, and the turntable 9 is vertically provided with a support shaft 14 that is rotatably connected to the mounting plate 4. The mining soft starter 6 is installed on the turntable 9. The lower end of the mounting plate 4 is provided with a positioning mechanism corresponding to the support shaft 14. The positioning mechanism fixes the position of the support shaft 14 and restricts the rotation of the support shaft 14. When connecting the cable to the mining soft starter 6, in order to facilitate the connection of the cable located at the rear end of the high-voltage soft starter, the restriction of the positioning mechanism on the support shaft 14 is released, and the turntable 9 is rotated so that the rear side of the high-voltage soft starter is rotated to the front or side, which facilitates the connection of the cable.

[0021] When installing the mining soft starter 6, the operating limit mechanism releases the limit between the mounting plate 4 and the support rod 3, pulls out the mounting plate 4, and installs the high-voltage soft starter on the upper end of the turntable 9. When connecting the cable, in order to facilitate the connection of the cable located at the rear end of the high-voltage soft starter, the positioning mechanism restricts the support shaft 14, and the turntable 9 is rotated so that the rear side of the high-voltage soft starter is rotated to the front or side, which facilitates the connection of the cable. After the installation is completed, the turntable 9 is rotated back and the positioning mechanism is used to fix the support shaft 14. The mounting plate 4 is pushed back and the position of the mounting plate 4 is fixed by the limit mechanism.

[0022] Example 2: A removable mounting base for a mining high-voltage soft starter is installed inside an explosion-proof housing 1. It includes a vertical plate 2, which is bolted to the explosion-proof housing 1. Support rods 3 are horizontally arranged on both sides of the lower end of the vertical plate 2, and are perpendicular to the plane of the vertical plate 2. A mounting plate 4 is slidably arranged between the two support rods 3. The mounting plate 4 has two through holes and slides in the front-back direction. Two damping rods 5 are horizontally arranged on the vertical plate 2, parallel to the support rods 3. The free ends of the damping rods 5 are fixedly connected to the mounting plate 4. The damping rods 5 are existing technology and will not be described further here. The damping rods 5 prevent the mounting plate 4 from sliding rapidly, reducing the impact vibration on the mining soft starter 6 caused by the rapid sliding of the mounting plate 4.

[0023] The end of the mounting plate 4 is provided with a limiting mechanism corresponding to the support rod 3. The limiting mechanism includes a horizontally extending double-headed telescopic rod 7, which is perpendicular to the support rod 3. The inner side of the end of the support rod 3 is provided with a limiting hole 8 corresponding to the double-headed telescopic rod 7. The double-headed telescopic rod 7 is existing technology and will not be described in detail here. When both ends of the double-headed telescopic rod 7 correspond to the limiting hole 8 on the same side, when the double-headed telescopic rod 7 extends and inserts into the corresponding limiting hole 8, the limiting mechanism restricts the position of the mounting plate 4 to prevent the mounting plate 4 from sliding on the support rod 3 under the action of external force, so as to stabilize the installation position of the mine soft starter 6.

[0024] A turntable 9 is rotatably mounted on the upper end of the mounting plate 4. A support shaft 14, which is rotatably connected to the mounting plate 4, is vertically mounted on the turntable 9. A mining soft starter 6 is mounted on the turntable 9. A positioning mechanism corresponding to the support shaft 14 is provided at the lower end of the mounting plate 4. The positioning mechanism includes a spring telescopic rod 10 and an external gear ring 11. The external gear ring 11 is coaxially fixed on the outside of the support shaft 14. The spring telescopic rod 10 extends radially along the external gear ring 11 and extends to the front end of the mounting plate 4 and is parallel to the support rod 3. A protective cover 12 is provided on the outside of the external gear ring 11. The protective cover 12 has a notch 13 corresponding to the spring telescopic rod 10. The protective cover 12 serves to protect the external gear ring 11.

[0025] The spring telescopic rod 10 includes an outer tube 101, a spring is installed inside the outer tube 101, and an inner shaft 102 is inserted inside the spring. Both ends of the inner shaft 102 extend to the outside of the outer tube 101. The two ends of the spring are fixedly connected to the outer tube 101 and the inner shaft 102, respectively. A limit plate 103 is provided on the side of the inner shaft 102 near the outer gear ring 11. When the inner shaft 102 is inserted between two teeth of the outer gear ring 11, it restricts the rotation of the outer gear ring 11, thereby fixing the position of the support shaft 14 by the positioning mechanism and restricting the rotation of the support shaft 14.

[0026] When connecting cables to the mining soft starter 6, in order to facilitate the connection of cables located at the rear end of the high-voltage soft starter, the positioning mechanism restricts the support shaft 14, and the turntable 9 is rotated so that the rear side of the high-voltage soft starter is rotated to the front or side, which facilitates the connection of cables.

[0027] The specific working process is as follows: When installing the mine soft starter 6, the operating limit mechanism releases the limit between the mounting plate 4 and the support rod 3, pulls out the mounting plate 4, and installs the high-voltage soft starter on the upper end of the turntable 9. When connecting the cable, in order to facilitate the connection of the cable located at the rear end of the high-voltage soft starter, the positioning mechanism restricts the support shaft 14, and the turntable 9 is rotated so that the rear side of the high-voltage soft starter is rotated to the front or side, which facilitates the connection of the cable. After the installation is completed, the turntable 9 is rotated back and the positioning mechanism is used to fix the support shaft 14. The mounting plate 4 is pushed back and the position of the mounting plate 4 is fixed by the limit mechanism, which facilitates the installation of the mine soft starter 6 and the connection of the cable, making it convenient to use.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
