Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a mobile explosion-proof dust collector. Background Technology

[0002] Explosion-proof dust collectors are specialized industrial equipment used to treat flammable and explosive dust. To facilitate movement, rollers are typically installed at the bottom of the dust collector. However, in practice, thresholds are commonly found at workshop entrances and equipment partitions. Because explosion-proof dust collectors require explosion-proof motors and pressure relief devices to ensure their explosion-proof performance, the entire device is quite heavy, making it difficult to move the dust collector over these thresholds using only rollers. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that in order to ensure the explosion-proof performance of the explosion-proof dust collector, it is necessary to use explosion-proof motors, pressure relief devices, etc., which makes the entire device heavy and difficult to cross the threshold by relying solely on rollers, thus making it difficult for the explosion-proof dust collector to move. Therefore, a mobile explosion-proof dust collector is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mobile explosion-proof dust collector is designed, including a mounting plate on which the explosion-proof dust collector is mounted. Support legs are fixedly connected to all four sides of the lower end of the mounting plate, and each of the four support legs is equipped with a second support wheel. Fixing blocks are fixedly connected to all four sides of the lower surface of the mounting plate. Rotating shafts are rotatably connected to two opposing fixing blocks via bearings. Rotating legs are fixedly connected to both ends of the two rotating shafts. The two rotating shafts rotate via a rotating mechanism, and a first support wheel is rolled at the lower end of each rotating leg.

[0006] Preferably, a pushing part is fixedly connected to one end of the mounting plate.

[0007] Preferably, the rotating mechanism includes gears, and gears are fixedly connected to the middle positions of the two rotating shafts. Each of the two gears is meshed with a rack, and the two racks are moved by a moving mechanism.

[0008] Preferably, the rack and gear are made of medium carbon alloy steel.

[0009] Preferably, the moving mechanism includes a bidirectional telescopic rod, which is fixedly connected to the lower surface of the mounting plate, and both ends of the bidirectional telescopic rod are fixedly connected to a rack.

[0010] Preferably, the bidirectional telescopic rod is a bidirectional hydraulic telescopic rod.

[0011] Preferably, a protective shell is fixedly connected to the lower surface of the mounting plate, the rack and gear are located inside the protective shell, and the protective shell is rotatably connected to the rotating shaft through a bearing.

[0012] Preferably, the bearing is a sealed bearing.

[0013] The mobile explosion-proof dust collector proposed in this utility model has the following advantages: the rotating mechanism drives the rotating shaft to rotate, which in turn causes the rotating leg to rotate, allowing the device to be supported by the first support wheel. This pushes the device so that the second support wheel can pass through the threshold. Then, the rotating leg rotates, causing the first support wheel to rotate, and the device is supported by the second support wheel. By switching between the first and second support wheels to support the device, the first and second support wheels can pass through the threshold separately, thus facilitating the device's passage through the threshold without the need for manual handling.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-4A mobile explosion-proof dust collector includes a mounting plate 2 on which an explosion-proof dust collector 1 is mounted. Support legs 4 are fixedly connected to the lower end of the mounting plate 2 around its perimeter. Each of the four support legs 4 is equipped with a second support wheel 13. During normal use, the second support wheels 13 support the device, preventing damage to the rotating mechanism caused by long-term support from the first support wheels 5. Both the first support wheels 5 and the second support wheels 13 are made of polyurethane material, which has good load-bearing capacity and wear resistance, preventing damage to the support wheels and extending their service life.

[0021] The lower surface of the mounting plate 2 is fixedly connected to four fixing blocks 8. Two opposing fixing blocks 8 are rotatably connected to rotating shafts 7 via bearings. Rotating legs 9 are fixedly connected to both ends of the two rotating shafts 7. The two rotating shafts 7 rotate via a rotating mechanism. A first support wheel 5 is rolled at the lower end of each rotating leg 9. When the device needs to move over a threshold-like structure, the rotating mechanism drives the rotating shafts 7 to rotate, causing the rotating legs 9 to rotate. This allows the device to be supported by the first support wheel 5, pushing the device to allow the second support wheel 13 to pass over the threshold. Then, the rotating legs 9 rotate again, causing the first support wheel 5 to rotate, supporting the device through the second support wheel 13. By switching between using the first support wheel 5 and the second support wheel 13 to support the device, the first support wheel 5 and the second support wheel 13 can each pass over the threshold, facilitating the device's passage over thresholds without manual handling.

[0022] One end of the mounting plate 2 is fixedly connected to a pushing part 3. The design of the pushing part 3 is to allow for the movement of the pushing device.

[0023] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the rotating mechanism includes gears 12. Gears 12 are fixedly connected to the middle positions of the two rotating shafts 7. Racks 11 mesh on the two gears 12. The two racks 11 move through a moving mechanism. The moving mechanism drives the racks 11 to move towards each other or away from each other, thereby driving the two gears 12 to rotate, changing the tilt angle of the rotating leg 9, and changing the support state of the device.

[0024] The rack 11 and gear 12 are made of medium carbon alloy steel, which has the characteristics of high strength and good toughness, so as to bear load and extend the service life of the device.

[0025] The moving mechanism includes a bidirectional telescopic rod 10, which is fixedly connected to the lower surface of the mounting plate 2. Both ends of the bidirectional telescopic rod 10 are fixedly connected to the rack 11. The bidirectional telescopic rod 10 extends and retracts, causing the rack 11 to move, thereby causing the rack 11 to drive the gear 12 to rotate.

[0026] The bidirectional telescopic rod 10 is a bidirectional hydraulic telescopic rod, capable of providing a large pushing force to easily push the two racks 11, allowing the first support wheel 5 to support the device. After the bidirectional hydraulic telescopic rod moves to the designated position, the control system closes the oil circuits to both ends of the cylinder, sealing the hydraulic oil inside the cylinder. Since the oil cannot be compressed, it acts like a solid pillar, effectively preventing the piston rod from moving. As long as the hydraulic system is well-sealed and the oil circuits are not reopened, the piston rod will be firmly locked in the current position. This gives the bidirectional telescopic rod 10 a self-locking function, providing a stable limit to the racks 11 after movement stops.

[0027] Example 3: Reference Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, a protective shell 6 is fixedly connected to the lower surface of the mounting plate 2. The rack 11 and gear 12 are located inside the protective shell 6. The protective shell 6 is rotatably connected to the rotating shaft 7 via a bearing, which is a sealed bearing. By using the protective shell 6, the rack 11 and gear 12 are protected, preventing them from being exposed, avoiding the entry of dust, and preventing jamming during transmission between the rack 11 and gear 12.

[0028] When the device passes the threshold, the bidirectional telescopic rod 10 extends, causing the two racks 11 to move in opposite directions. The racks 11 drive the gears 12 to rotate, thereby driving the two gears 12 to rotate. The rotation of the two gears 12 drives the two rotating shafts 7, making the rotating leg 9 vertical. The first support wheel 5 supports the device, increasing the height of the device as follows. Figure 1-2 As shown, the pusher 3 moves the device, causing the front second support wheel 13 to pass over the threshold. Then, the bidirectional telescopic rod 10 extends and retracts, causing the two racks 11 to move in opposite directions. This causes the racks 11 to drive the gears 12 to rotate, which in turn drives the two gears 12 to rotate. The rotation of the two gears 12 drives the two rotating shafts 7, causing the rotating leg 9 to tilt and retract. The device is then supported again by the second support wheel 13. The device is then pushed to move, causing the first support wheel 5 to partially pass over the threshold. Finally, the first support wheel 5 is used to support the device again, causing the rear second support wheel 13 to also pass over the threshold, thus moving the entire device over the threshold.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
