Description

Technical Field

[0001] This utility model belongs to the field of lifting devices, and in particular relates to a lifting device that facilitates the disassembly of the conveying screw of a powder pulse bag dust collector. Background Technology

[0002] The powder pulse bag dust collector is equipped with a conveying screw structure at the bottom. The pulse bag dust collector and the conveying screw are connected by bolts. The number of bolts varies from dozens to hundreds depending on the size and length of the pulse bag dust collector.

[0003] Currently, when disassembling the conveyor screw, the method is to use two or three hand chain hoists to fix the conveyor screw. After all the bolts are removed, the hand chain hoists are used to slowly lower it. The whole operation process consumes a lot of manpower, about 8 man-days, and a lot of time, about 6 man-hours, and the safety factor is low.

[0004] Based on this, a lifting device for the conveying screw structure under the powder pulse bag dust collector has been developed. The lifting device supports and fixes the conveying screw, thereby facilitating the disassembly of the bolts on the conveying screw and making the conveying screw of the powder pulse bag dust collector easy to disassemble.

[0006] Technical solution: The present invention provides a lifting device for facilitating the disassembly of the conveying screw of a powder pulse bag dust collector, comprising a hydraulic lifting platform and a sliding support device disposed on the hydraulic lifting platform; the sliding support device includes a left support block and a right support block, both of which are provided with inclined surfaces, and the inclined surfaces of the left support block and the right support block are arranged facing each other, and a spring with one end respectively disposed on the left support block and the right support block to support and position the sliding of the two, and the other end of the spring is connected to a fixed plate on the lifting platform.

[0007] Furthermore, the lifting device also includes a connecting plate on the hydraulic lifting platform, which is provided with a sliding guide rail. The bottom ends of the left support block and the right support block are respectively provided with sliders that cooperate with the sliding guide rail.

[0008] Furthermore, the lifting device has two sets of moving guide rails, located on both sides of the connecting plate, and sliders are matched on both sides of the bottom end of the left and right support blocks.

[0009] Furthermore, the lifting device has two sets of springs, located on either side of the left or right support block.

[0010] Furthermore, the fixing plate of the lifting device is located at both ends of the connecting plate.

[0011] Furthermore, the bottom of the hydraulic lifting platform of the lifting device is equipped with movable wheels.

[0012] Beneficial effects: Compared with the prior art, the advantages of this utility model are that the lifting device is used for disassembling the conveying screw of the powder pulse bag dust collector. By setting sliding left and right support blocks with inclined surfaces, it can support the conveying screw of powder pulse bag dust collectors of different specifications, and improve the stability of the support, thereby increasing its applicability and flexibility. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the lifting device of this utility model. Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] The lifting device of this utility model is used to support the conveying screw of a powder pulse bag dust collector, facilitating the removal of bolts on the conveying screw and enabling easy disassembly of the conveying screw of the powder pulse bag dust collector. Specifically, as shown... Figure 1 As shown, the lifting device includes a hydraulic lifting platform 1 and a sliding support device mounted on the hydraulic lifting platform 1. The bottom end of the hydraulic lifting platform 1 is equipped with movable wheels 9, which facilitates its position movement. The height of the sliding support device can be adjusted by the hydraulic lifting platform 1 to suit different working conditions.

[0016] The sliding support device includes a connecting plate 6 mounted on the platform of the hydraulic lifting platform 1. The connecting plate 6 has a slidable support block assembly, and fixed plates 5 are located at both ends of the connecting plate 6. The sliding support block assembly includes a left support block 2 and a right support block 3, both of which have inclined surfaces facing each other. These inclined surfaces support the conveying screw to be supported. Springs 4 are located on the sides of the left and right support blocks 2 and 3 away from the inclined surfaces, respectively, to support the movement of the left and right support blocks 2 and 3 and to position them for reset. Specifically, one end of the spring 4 is located on the support block, and the other end is located on the fixed plates 5 at both ends of the connecting plate 6.

[0017] The upper surface of the connecting plate 6 is provided with a sliding guide rail 7. Correspondingly, the left support block 2 and the right support block 3 are provided with sliders 8 that cooperate with it. That is, under the action of the sliders 8, the sliding guide rail 7 and the spring 4, when the conveying screw acts on the inclined surface of the left support block 2 and the right support block 3, the left support block 2 and the right support block 3 can move in opposite directions until the conveying screw is supported and stabilized. After the disassembly of the conveying screw is completed, it can be returned to its original position under the reaction action of the spring 4.

[0018] The sliding guide rail 7 of this invention is preferably provided in two sets, located on both sides of the connecting plate 6. Correspondingly, sliders 8 are provided on both sides of the bottom end of the left support block 2 and the right support block 3. The spring 4 is also preferably provided in two sets, located on both sides of the left support block 2 or the right support block 3.
