Description

Technical Field

[0001] This utility model relates to the field of explosion-proof soft starter housings, specifically an onboard device for explosion-proof soft starter housings. Background Technology

[0002] Explosion-proof soft starters are key equipment in the industrial field used to smoothly start high-power motors and prevent current surges. Because their core electronic components (such as thyristors and control boards) generate a lot of heat during operation and require frequent maintenance, repair or replacement, they are usually installed in a special housing that combines heat dissipation and explosion protection. Installing heavy and structurally precise explosion-proof soft starters into the housing is a difficult and risky task.

[0003] Traditional operation methods often rely on manual handling or the use of simple slide rails. During the process of pushing the device into the housing, it is difficult to accurately control the final position, and there is no effective locking mechanism after the device is in place. During the transportation or use of the equipment, vibration may cause it to move inside the housing, affecting the reliability of electrical connections and even causing safety accidents. Therefore, a device for loading an explosion-proof soft start housing is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] An explosion-proof soft starter housing mounting device, such as Figures 1-5 As shown, the device includes a rectangular outer shell 1 with an open end and a hollow interior. Inside the outer shell 1, a trolley 5 for installing an explosion-proof soft starter is installed. The trolley 5 has wheels at the bottom for easy movement. The trolley 5 can be detached from the bracket 3 or slide onto the bracket 3 into the outer shell 1. A locking plate 8 is fixed to one end of the trolley 5, and a slot is provided in the locking plate 8. A cabinet door 2 is installed on one side of the open end of the outer shell 1 via a hinge for closing or opening the outer shell 1. A rotating handle 9 is rotatably installed on the outer wall of the outer shell 1 via a bearing. A handle 10 is fixed to the side wall of the rotating handle 9. A locking assembly is provided on the inner wall of the outer shell 1. The handle 10 drives the rotating handle 9 to rotate, and the rotating shaft of the rotating handle 9 extends into the outer shell 1 to drive the locking assembly to operate, so that the output end of the locking assembly enters the slot of the locking plate 8, pulling the trolley 5 to a designated position. When the rotating handle 9 and the handle 10 are locked, the locking assembly locks the position of the trolley 5.

[0024] The locking assembly includes a rotating seat 12 and a rotating seat 2 14. Both rotating seats 12 and 2 14 are rotatably mounted on the inner wall of the outer casing 1 via a rotating shaft. The rotating shaft of the handle 9, which extends into the outer casing 1, is fixedly connected to the rotating shaft of the rotating seat 12. Fixed handle 13 and fixed handle 2 15 are fixedly connected to one side of both rotating seats 12 and 2 14. A connecting rod 16 is rotatably mounted between the fixed handle 13 and fixed handle 2 15 via a rotating shaft. When the handle 9 drives the rotating seat 12 to rotate, the fixed handle 13 pulls or pushes the fixed handle 2 15 via the connecting rod 16, causing the rotating seat 2 14 to rotate synchronously.

[0025] A rotating rod 17 is fixedly connected to the center of the rotating base 14. A rear drive handle 18 is fixedly connected to the side wall of the rotating rod 17. The end of the rear drive handle 18 engages with the clamping plate 8. The end of the rear drive handle 18 pulls the trolley 5 to the designated position. When the trolley 5 is pushed into the outer shell 1, the end of the rear drive handle 18 prevents the trolley 5 from continuing to enter the outer shell 1. When the rotating base 14 drives the rotating rod 17 to rotate, the end of the rear drive handle 18 rises upward and enters the clamping groove of the clamping plate 8. As the rear drive handle 18 continues to rotate, it pulls the trolley 5 to the designated position.

[0026] A front drive handle 19 is fixedly connected to the center of the rotating seat 12. The end of the front drive handle 19 is used to press the end of the trolley 5 away from the card plate 8. Before the trolley 5 enters the outer shell 1, the end of the front drive handle 19 contacts the bottom wall of the outer shell 1. The trolley 5 enters the outer shell 1 from the upper end of the front drive handle 19. When the rotating handle 9 drives the rotating seat 12 to rotate, the rear drive handle 18 and the front drive handle 19 move at the same time. The front drive handle 19 pushes the trolley 5 and the rear drive handle 18 pulls the trolley 5. The front and rear work together to move the trolley 5 to the designated position.

[0027] Both the outer shell 1 and the cabinet door 2 (which has a certain thickness) have interlocking holes 7 (which fit the size of the locking rod 11). The locking rod 11 is threaded onto the outer wall of the outer shell 1. One end of the locking rod 11 is inserted into the hole 7, and the other end is engaged with the slot 21 on the side wall of the handle 9. A slot 20 is inserted and slidably inserted into the side wall of the outer shell 1. The slot 20 is engaged with the slot 21. When the trolley 5 enters the outer shell 1, the storage bracket 3 is retracted, the cabinet door 2 is closed, and the locking rod 11 is rotated so that one end of the locking rod 11 is inserted into the hole 7, locking the cabinet door 2, and the other end is disengaged from the handle 9. The slot 20 is pulled outward so that the smaller diameter position of the slot 20 corresponds to the slot 21, and the handle 9 can rotate. Similarly, when the slot 20 is pressed, the larger diameter position of the slot 20 corresponds to the slot 21, and the slot 20 is engaged with the slot 21, preventing the handle 9 from rotating.

[0028] One end of the bracket 3 is rotatably mounted to the lower end of the inner wall of the outer shell 1, and support plates 4 are rotatably mounted on both sides of the bracket 3.

[0029] When not in use, the bracket 3 can be flipped upwards and retracted into the housing 1. When in use, it is flipped downwards and lowered. The support plates 4 (rectangular) on both sides are rotated so that the bottom of the support plates 4 is supported on the ground. The trolley 5 moves on the bracket 3 into the housing 1.

[0030] The working principle of the explosion-proof soft starter housing mounting device provided by this utility model is as follows:

[0031] When using this loading device, install the explosion-proof soft starter on the trolley 5, open the cabinet door 2, flip the bracket 3 downwards and lower it, and let the support plate 4 support the ground. Push the trolley 5 with the explosion-proof soft starter installed onto the bracket 3, and push it along the bracket 3 into the outer shell 1 until the front plate 8 of the trolley 5 slightly abuts against the rear drive handle 18 inside the outer shell 1. At this time, the trolley 5 is inside the outer shell 1. Flip the bracket 3 upwards and retract it into the outer shell 1. Close the cabinet door 2, turn the handle 10 and the rotating handle 9. The rotating handle 9 drives the rotating seat 12 to rotate, which is connected to the connecting rod 16. The drive rotating base 14 rotates synchronously, the rear drive handle 18 pulls the trolley 5, and the front drive handle 19 pushes the trolley 5. The trolley 5 is moved smoothly and accurately to the designated working position inside the outer shell 1. The locking seat 20 is pressed, and the larger diameter position of the locking seat 20 corresponds to the locking slot 21. The locking seat 20 and the locking slot 21 are engaged, preventing the rotating handle 9 from rotating, so that the locking component is locked and the position of the trolley 5 is fixed. This eliminates the problem of inaccurate positioning when manually loading the vehicle, improves the installation accuracy and efficiency, and the positioning of the rotating handle 9 effectively prevents the trolley 5 from accidentally sliding out due to vibration during equipment operation or transportation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
