[0033] As Figure 1As shown, a boiler dust cloth replacement device includes a bottom plate 10, two supports 11, two lifting members 13, a support plate 12, a hook assembly and two limiting assemblies; the bottom plate 10 is horizontally placed, and a light hole 101 for the dust cloth to pass through is formed in the middle part thereof; the two hollow supports 11 are vertically arranged on the sides of the light hole 101; the two lifting members 13 are respectively slidably arranged in the interiors of the corresponding supports 11, and the output ends of the two lifting members 13 can be close to or away from the bottom plate 10; the support plate 12 is arranged on the output ends of the two lifting members 13, and the plate surface of the support plate 12 is parallel to the plate surface of the bottom plate 10; the hook assembly is arranged on the side plate surface of the support plate 12 close to the bottom plate 10, and is used for lifting the dust cloth; the two limiting assemblies are respectively arranged on the peripheral parts of the corresponding supports 11, and the working ends of the two limiting assemblies can be close to or away from the hole core of the light hole 101, and can constrain the lowering or lifting path of the dust cloth, and the constraint area formed thereby is adapted to the volume of the dust cloth.

[0034] In the above scheme, when the dust cloth needs to be replaced, first, the lifting member 13 is started to make the support plate 12 and the hook assembly descend to the appropriate position. The hook assembly is operated to lift the dust cloth to be replaced. Then, the support plate 12, the hook assembly and the dust cloth are lifted to a certain height by the lifting member 13 to ensure that the dust cloth can be smoothly pulled out of the boiler dust removal system. At the same time, the working end of the limiting assembly is adjusted to be close to the hole core of the light hole 101 to form a constraint area adapted to the volume of the dust cloth, so as to prevent the dust cloth from swinging or scratching during the lifting process. When the dust cloth is completely pulled out, it is taken off from the hook assembly, and then a new dust cloth is installed. Finally, the new dust cloth is lowered to the appropriate position by the lifting member 13, and the limiting assembly is adjusted to release the constraint area, and the replacement process is completed. In practice, the lifting member 13 in the present application can directly use telescopic air cylinders, and the output ends thereof are fixedly connected with the bottom of the support plate 12, and the two telescopic air cylinders together drive the support plate 12 to rise or descend.

[0035] The present application realizes the quick and convenient replacement of the dust cloth by the cooperation of the lifting member 13 and the hook assembly, and improves the replacement efficiency of the dust cloth. The setting of the limiting assembly effectively prevents the dust cloth from swinging and scratching during the replacement process, and protects the integrity of the cloth bag. By adjusting the working end of the limiting assembly, a constraint area adapted to dust cloths of different volumes can be formed, which enhances the adaptability and flexibility of the device and is suitable for boiler dust removal systems of different models and specifications.

[0036] The hook assembly comprises two fixing plates 20, a wire reel 21, a rope 22, a hook 23 and a driving member 24. The two fixing plates 20 are arranged at intervals on the side surface of the support plate 12 close to the bottom plate 10, and the midpoint between the two fixing plates 20 is coaxially arranged with the hole core of the light hole 101. The wire reel 21 is rotationally arranged between the two fixing plates 20. One end of the rope 22 is wound around the middle part of the wire reel 21, and the other end thereof is freely extended downward. The hook 23 is fixedly arranged at the end of the rope 22 away from the middle part of the wire reel 21, and can move up and down within the constraint area of the two limiting assemblies. The driving member 24 is arranged beside the wire reel 21, and the output end thereof is fixedly connected with the wire reel 21.

[0037] In the above scheme, when it is necessary to lift or lower the hook 23 and the objects hung thereon, the driving member 24 is started. The output end of the driving member 24 rotates to drive the wire reel 21 to rotate, and the rotation of the wire reel 21 causes the rope 22 wound thereon to tighten or loosen, thereby driving the hook 23 to rise or fall, realizing the rapid up-and-down movement of the hook 23 and improving the work efficiency. The up-and-down movement of the hook 23 can be adjusted by controlling the rotation direction and speed of the driving member 24, thereby meeting different work requirements. When the hook 23 reaches the required height or position, the driving member 24 is stopped. The wire reel 21 stops rotating, the rope 22 remains in the current state, and the hook 23 and the hung objects are stable at the current position. The hook assembly in the present application can be widely applied to various scenes requiring lifting or lowering of objects, such as warehouses, factories, logistics centers, etc., and the material, size, etc. of the hook 23 and the rope 22 can be adjusted to meet the weight, volume, etc. requirements of different objects.

[0038] The limiting assembly comprises a connecting rod 30, a limiting plate 31 and a hand wheel 32. The connecting rod 30 is horizontally arranged in the corresponding support 11 and located beside the lifting member 13. The limiting plate 31 is arranged at one end of the connecting rod 30 close to the light hole 101, and the side surface of the limiting plate 31 close to the light hole 101 abuts against the peripheral surface of the dust removal bag. The middle part of the hand wheel 32 penetrates through the peripheral part of the connecting rod 30 and is rotationally connected with the peripheral part of the corresponding support 11, and can drive the connecting rod 30 to approach or move away from the hole core of the light hole 101.

[0039] In the above scheme, when it is necessary to adjust the position of the dust removal cloth bag or limit its moving range, the hand wheel 32 is rotated, the rotation of the hand wheel 32 drives the connecting rod 30 to move along the horizontal direction, and the two limiting plates 31 on the sides are close to or away from the hole core of the light hole 101. When the limiting plate 31 is close to the dust removal cloth bag, the plate surface abuts against the peripheral surface of the dust removal cloth bag, thereby limiting the movement of the dust removal cloth bag. Conversely, when the limiting plate 31 is away from the dust removal cloth bag, the moving range of the dust removal cloth bag is increased. After the adjustment is completed, the hand wheel 32 is kept at the required position, and the connecting rod 30 and the limiting plate 31 are also kept stable and immobile. The limiting plate 31 continues to limit the dust removal cloth bag, preventing the dust removal cloth bag from shaking or shifting during operation. Moreover, a threaded hole is formed in the middle of the hand wheel 32 in the present application, and a thread is formed on the peripheral surface of the connecting rod 30, and the two are in gear transmission.

[0040] The end of the limiting plate 31 away from the bottom plate 10 is vertically arranged, and the end of the limiting plate 31 close to the bottom plate 10 is circularly arranged and sequentially arranged with the hole of the light hole 101.

[0041] In the above scheme, during operation, the position of the connecting rod 30 and the limiting plate 31 is adjusted by rotating the hand wheel 32, so that the limiting plate 31 is close to or away from the dust removal cloth bag. When the limiting plate 31 is close to the dust removal cloth bag, the vertical section can be in close contact with the side surface of the dust removal cloth bag, preventing it from moving excessively in the horizontal direction. The end of the limiting plate 31 close to the bottom plate 10 is designed in a circular shape and sequentially arranged with the hole of the light hole 101, which is to adapt to the shape and moving path of the dust removal cloth bag, so as to more smoothly guide the dust removal cloth bag to enter or leave the light hole 101, and reduce the friction and resistance caused by the shape mismatch.

[0042] The plate surface of the end of the limiting plate 31 away from the bottom plate 10 close to the light hole 101 is provided with a limiting groove 311 for restricting the lowering or winding path of the rope 22, and the groove opening of the limiting groove 311 is towards the hole core side of the light hole 101.

[0043] In the above scheme, during operation, one end of the rope 22 is connected with the hook 23, and the other end is wound on the wire wheel 21. When it is necessary to lift or lower the hook 23, the driving part 24 is started to drive the wire wheel 21 to rotate, thereby tightening or loosening the rope 22. During the tightening or loosening process of the rope 22, it will be restricted by the limiting groove 311 and move along the set path. The limiting groove 311 not only ensures the stable movement of the rope 22, but also ensures that the rope 22 will not deviate from the predetermined path during movement due to accidental circumstances, thereby enhancing the safety of the whole system.

[0044] In order to realize that the operator can quickly move the whole structure without using other carrying tools or equipment, in order to realize the purpose of saving time and effort. The bottom of the bottom plate 10 is fixedly provided with universal wheels 14, which are provided with four, so that the whole structure can be easily moved and turned on the ground, improving the flexibility of operation.

[0045] It can be implemented that the circumferential surface of the four universal wheels 14 is sleeved with a shock absorbing ring, and the width of the shock absorbing ring is consistent with the width of the corresponding universal wheel 14.

[0046] When the whole structure encounters uneven ground or obstacles during movement, the universal wheels 14 will be impacted and vibrated. The shock absorbing ring can absorb and disperse these impact forces, reducing the influence of vibration on the structure itself and the surrounding environment. At the same time, since the width of the shock absorbing ring is consistent with the width of the universal wheel 14, it can ensure that the contact area of the universal wheel 14 with the ground remains stable during movement, thereby improving the stability and safety of movement.

[0047] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly explains the difference from other embodiments.

[0048] The above examples are only used to illustrate the technical solutions of the present application, and are not limited to the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
