Sometimes the contaminated areas are high and cover a large area, making it difficult to clean and thus affecting the overall quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide a roller-surface dust-proof lifting auxiliary device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a roller-type dust-proof lifting auxiliary device, comprising: a lifting frame; a hook ring connected to an external crane; two connecting rings symmetrically fixed on the lifting frame; two chains fixed between the hook ring and the two connecting rings by a plurality of butterfly buckles; an adjustment assembly disposed within the lifting frame; two slings connected to the adjustment assembly by the two butterfly buckles; dust-blocking plates disposed at the lower ends of the two slings; two support frames symmetrically fitted onto the bottom of the dust-blocking plates and respectively fixedly connected to the two slings; a plurality of connecting ropes, one end of which is fixedly connected to the two slings and the other end of which is fixedly connected to both ends of the two support frames; two adjusting components disposed on the dust-blocking plates and the two slings; and a dust-blowing assembly installed on the dust-blocking plates.

[0006] The adjusting assembly is adapted to control the upper ends of the two slings to move closer or further apart from each other;

[0007] The two adjusting members are adapted to be positioned after the two support frames are moved closer or further apart;

[0008] The dust blowing assembly is adapted to blow away dust placed at the edge of the dust baffle.

[0009] Furthermore, the adjusting component includes an adjusting groove formed on the dust baffle plate, a positioning seat slidably disposed in the adjusting groove and fixedly connected to the upper surface of one of the support frames, and a positioning screw threadedly connected to one of the support frames;

[0010] The positioning seat is fixedly connected to one of the slings;

[0011] The head end of the positioning screw abuts against the lower surface of the dust baffle plate.

[0012] Furthermore, the adjusting component also includes a connecting frame fixed on the positioning seat, two positioning plates fixed on the dust baffle plate, and two accordion covers with one end fixedly connected to both sides of the connecting frame and the other end fixedly connected to the two positioning plates.

[0013] Furthermore, the adjustment assembly includes two control slots symmetrically opened in the lifting frame, a double-acting screw rotatably installed in the two lifting frames via several bearings, two adjusting blocks threadedly installed at both ends of the double-acting screw and slidably installed in the two control slots, two pull rings fixed to the bottom of the two adjusting blocks, two movable slots symmetrically opened at the bottom of the lifting frame and allowing the two pull rings to move, and a rotating handle fixed to one end of the double-acting screw;

[0014] The two slings are respectively connected to the two pull rings via butterfly buckles.

[0015] Furthermore, the soot blowing assembly includes an air blowing ring pipe fixedly connected to the upper surface of the soot baffle plate, a plurality of air blowing holes equally spaced on the air blowing ring pipe, a plurality of air guide pipes connected at one end to the air blowing ring pipe, an air inlet pipe connected to the other end of the plurality of air guide pipes, a bracket fixed to the soot baffle plate, and an air pump mounted on the bracket.

[0017] Furthermore, the lower surface of the dust baffle plate is symmetrically provided with two sets of scale grooves, and the two positioning screws correspond to the two scale grooves respectively.

[0018] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0019] This roller-face dust-proof lifting auxiliary device, through its dust-blocking plate and dust-blowing component, can effectively shield and protect the top of the roller-faced workpiece during the lifting process. It also provides a certain dust-proof effect around the dust-blocking plate. Thus, during the lifting of the roller-faced workpiece, it can effectively prevent dust, paint peeling, and other contaminants from the external crane beam, motor, hook, sling, or rope from falling onto the roller-faced workpiece. It provides good protection for the top of the roller-faced workpiece and prevents the painted roller-faced workpiece from being affected by dust and debris.

[0020] This roller surface dust-proof lifting auxiliary device, through its adjustable components and two positioning parts, can effectively control the distance between the upper and lower ends of the two slings, thus facilitating the lifting of roller surface workpieces of different sizes. It is highly practical. When lifting different roller surface workpieces, both slings can remain taut, reducing the lateral force on the two support frames. This ensures that the dust-blocking plate can stably perform its dust-blocking function when lifting roller surface workpieces of different sizes. During use, the distance between the two slings is slightly smaller than the workpiece being lifted, allowing the lower ends of the slings to be close to both ends of the roller surface workpiece, facilitating connection between the lower ends of the slings and the ends of the workpiece and improving lifting efficiency.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] like Figure 1-5 As shown, a roller-type dust-proof lifting auxiliary device includes: a lifting frame 1; a hook 2 connected to an external crane; two connecting rings 3 symmetrically fixed on the lifting frame 1; two chains 4 fixed between the hook 2 and the two connecting rings 3 by several butterfly buckles; an adjustment assembly 5 disposed within the lifting frame 1; two slings 6 connected to the adjustment assembly 5 by the two butterfly buckles; dust-blocking plates 7 disposed at the lower ends of the two slings 6; two support frames 8 symmetrically fitted onto the bottom of the dust-blocking plates 7 and fixedly connected to the two slings 6 respectively; several connecting ropes 9, one end of which is fixedly connected to the two slings 6 respectively, and the other end of which is fixedly connected to both ends of the two support frames 8 respectively; two adjusting components 10 disposed on the dust-blocking plates 7 and the two slings 6; and a dust-blowing assembly 11 installed on the dust-blocking plates 7.

[0031] The adjustment component 5 is adapted to control the upper ends of the two slings 6 to move closer or further apart from each other;

[0032] The two adjusting members 10 are adapted to be positioned after the two support frames 8 are moved closer or further apart;

[0033] The dust blowing assembly 11 is adapted to blow away dust placed at the edge of the dust baffle 7. In use, the hook 2 is pre-connected to the hook of the external crane. The two chains 4 ensure that the lifting frame 1 is in a horizontal state. The adjusting assembly 5 controls the upper ends of the two slings 6 to move closer or further apart, so that the distance between the upper ends of the two slings 6 is slightly less than the length of the workpiece to be lifted. Then, the two adjusting components 10 are released from their limiting position on the two support frames 8. At this time, the lower ends of the two slings 6 can be connected to the lifting roller. The two ends of the workpiece are connected, so that the two slings 6 are taut, allowing the two support frames 8 to move to the appropriate position of the dust baffle 7. The two adjusted support frames 8 can be positioned by the two adjusting parts 10. When the workpiece is being lifted, the dust baffle 7, together with the several bellows covers 17 in the two adjusting parts 10, can effectively shield the top of the workpiece, effectively preventing dust, peeling paint, and other debris from the external crane beam, motor, hook, or slings 6 or ropes from falling onto the surface of the workpiece. To avoid contaminating the surface of the painted roller workpiece and ensure its processing quality; and when hoisting roller workpieces of a single specification, the taut two lifting locks are less likely to exert lateral force on the two support frames 8, thus preventing excessive lateral force on the two support frames 8 during workpiece hoisting, which would affect the positioning effect of the two adjusting parts 10 on the two support frames 8, ensuring that the dust baffle 7 will not be skewed or shifted, thus affecting its shielding effect on the roller workpiece; and during subsequent continuous hoisting of roller workpieces, the lower ends of the two lifting cables 6 are respectively close to the roller. The two ends of the workpiece facilitate the connection between the two slings 6 and the workpiece, optimizing the lifting process. During use, under the control of the adjusting component 5 and the two adjusting components 10, the distance between the upper and lower ends of the two slings 6 can be adjusted to accommodate workpieces of different lengths, thus facilitating the lifting of workpieces of different specifications. During lifting, the dust blowing component 11 can effectively increase the dust blocking area of ​​the dust baffle 7, further improving the dust baffle 7's shielding effect on the top of the workpiece and preventing the painted workpiece from being contaminated.

[0034] Optionally, the adjusting component 10 includes an adjusting groove 12 formed on the dust baffle plate 7, a positioning seat 13 slidably disposed in the adjusting groove 12 and fixedly connected to the upper surface of one of the support frames 8, and a positioning screw 14 threadedly connected to one of the support frames 8.

[0035] The positioning seat 13 is fixedly connected to one of the slings 6;

[0036] The head end of the positioning screw 14 abuts against the lower surface of the dust baffle 7. After adjusting the distance between the upper ends of the two slings 6 to be slightly less than the length of the roller surface part material to be lifted by adjusting the component 5, the restriction on the position of the two support frames 8 is released by rotating the two positioning screws 14 in the two adjusting components 10. At this time, the lower ends of the two slings 6 can be connected to the two ends of the roller surface part material respectively, so that the two support frames 8 drive the two positioning seats 13 to move in the two adjusting grooves 12, so that the two slings 6 are kept taut and the position of the two support frames 8 is determined. Then, the two positioning screws 14 are rotated to approach and abut against the dust baffle. Plate 7 positions the two support frames 8, effectively reducing the lateral force on the two support frames 8 when hoisting materials of a single specification of roller surface parts, preventing the two positioning screws 14 from loosening under stress and affecting the shielding effect of the dust baffle plate 7. When hoisting materials of different specifications of roller surface parts, the distance between the two support frames 8 can be adjusted so that the distance between the lower ends of the two slings 6 is similar to the length of the roller surface parts to be hoisted, thus facilitating the alignment of the lower ends of the two slings 6 with the two ends of the roller surface parts to be hoisted and simplifying the connection process between the lower ends of the two slings 6 and the roller surface parts to be hoisted.

[0037] Optionally, the adjusting component 10 further includes a connecting frame 15 fixed on the positioning seat 13, two positioning plates 16 fixed on the dust baffle 7, and two bellows covers 17, one end of which is fixedly connected to both sides of the connecting frame 15 and the other end of which is fixedly connected to the two positioning plates 16. In use, the bellows covers 17 can cover the two adjusting slots 12 in the two adjusting components 10, thereby preventing dust from falling through the two adjusting slots 12 to the bottom of the dust baffle 7 during use, and ensuring the dust protection effect when the roller surface parts are hoisted.

[0038] Optionally, the adjustment assembly 5 includes two control slots 18 symmetrically opened in the lifting frame 1, a double-acting screw 19 rotatably installed in the two lifting frames 1 via several bearings, two adjusting blocks 20 threadedly installed at both ends of the double-acting screw 19 and slidably installed in the two control slots 18, two pull rings 21 fixed to the bottom of the two adjusting blocks 20, two movable slots 22 symmetrically opened at the bottom of the lifting frame 1 and allowing the two pull rings 21 to move, and a rotating handle 23 fixed to one end of the double-acting screw 19;

[0039] The two slings 6 are connected to the two pull rings 21 via butterfly buckles. In use, the operator can rotate the double-acting screw 19 by turning the handle 23, thereby controlling the two adjusting blocks 20 to move within the two control slots 18. This controls the two adjusting blocks 20 to move closer or further apart from each other, and with the cooperation of the two pull rings 21, the distance between the upper ends of the two slings 6 is controlled. After adjusting the distance between the lower ends of the two slings 6 with the two adjusting parts 10, the distance between the two slings 6 is slightly shorter than the length of the roller surface material while ensuring that the two slings 6 are in a relatively vertical state. This facilitates the connection between the lower ends of the two slings 6 and the roller surface material, thereby facilitating the lifting of roller surface material of different sizes.

[0040] Optionally, the soot blowing assembly 11 includes an air blowing ring pipe 24 fixedly connected to the upper surface of the soot baffle plate 7, a plurality of air blowing holes 25 equally spaced on the air blowing ring pipe 24, a plurality of air guide pipes 26 connected at one end to the air blowing ring pipe 24, an air inlet pipe 27 connected to the other end of the plurality of air guide pipes 26, a bracket 28 fixed on the soot baffle plate 7, and an air pump 29 mounted on the bracket 28.

[0041] The air outlet of the air pump 29 is connected to the other end of the air inlet pipe 27. Specifically, depending on the convenience of actual processing and usage requirements, the cross-sectional shape of the several air blowing holes 25 can be square, rectangular, circular, elliptical, etc. When the roller surface part material is hoisted and transported, the air pump 29 works to deliver air into the air inlet pipe 27. With the cooperation of several air guide pipes 26, the airflow is evenly delivered to different positions of the air blowing ring pipe 24 and then blown out through several air blowing holes 25, so that the dust falling into the edge of the dust baffle 7 will be blown away from the dust baffle 7, effectively increasing the range of dust blocking by the dust baffle 7.

[0042] Optionally, the lower surface of the dust baffle 7 is symmetrically provided with two sets of scale grooves 30, and the two positioning screws 14 correspond to the two scale grooves 30 respectively. By using the two scale grooves 30, when adjusting and positioning the two support frames 8 through the two adjustment components 10, the consistency and accuracy of the position adjustment of the two support frames 8 on the dust baffle 7 can be ensured, avoiding the dust baffle 7 from tilting during use, which would affect the dust-proofing effect on the lifting roller surface parts of the two slings 6. At the same time, when the two adjustment components 10 are used, the heads of the two positioning screws 14 can increase the friction with the dust baffle 7 through the two scale grooves 30 respectively, thereby effectively improving the stability of the support frame 8 after adjustment.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
