The purpose of the utility model is to prevent the rollers from moving and increase the positioning function. At the same time, it provides a multifunctional all-round 360° lifting anti-falling bridge. It has a simple structure and can be used for the lifting and anti-falling functions of various complex internal parts of pressure vessels.

[0034] The utility model focuses on solving the problem of falling prevention and reliable and efficient operation when lifting and assembling complex internal parts inside the pressure vessel. The utility model realizes the 360° lifting and assembly positioning function of the internal parts from the outside of the equipment to the inside of the equipment through the cooperation of the monorail trolley and the hand hoist, and effectively protects the product quality to avoid bumps and scratches. The utility model adds the roller anti-stringing and positioning function, solves the safety accidents such as low manual operation efficiency and falling of internal parts during lifting, improves the efficiency of internal parts lifting and prevents the possibility of falling.

[0035] The utility model discloses a fall-proof bridge for hoisting the internal parts of a pressure vessel, which is a multifunctional and all-round hoisting device, comprising a supporting rib 1, a main roller positioning plate I2, a main roller positioning plate II3, a supporting ring 4, a roller sliding track 5, a main roller 6, a clamping plate 7, a nut I8, a connecting vertical plate I9, a connecting plate I10, an I-beam 11, a connecting plate II12, a positioning clamping plate 13, a bolt I14, a nut II15, a supporting tube 16, a secondary roller 17, a connecting vertical plate II18, a positioning plate 19, a screw I20, a connecting plate III21, a bolt II22, a nut III23, a washer I24, a washer II25, a screw II26, an angle steel 27, a baffle 28, a supporting support plate 29, a secondary roller positioning plate 30, and the like.

[0036] like Figure 1As shown, the support ring 4 and support cylinder 16 form the fixed support structure of the entire lifting device. The support cylinder 16 has a support plate 29 for the auxiliary rollers 17 at its bottom. The support ring 4 has 40 support ribs 1 at its lower portion and a roller sliding track 5 at its upper portion. The support ring 4 is connected to the support ribs 1, the main rollers 6, and the roller sliding track 5, providing support for the entire lifting device. The support cylinder 16 is mated with the end of the I-beam 11 and connected to the auxiliary rollers 17 and support plate 29 on the other side, assisting the main rollers 6 in sliding. Main roller positioning plates I2 and II3 are located above the support ring 4. The main roller 6 is placed between these two plates to prevent movement and provide a position limit to prevent the rollers from derailing and causing internal components to fall. Main roller positioning plates I2 and II3 are located on either side of the roller sliding track 5. The main roller positioning plate is connected to the support ring 4, and the main roller 6 is placed on the roller sliding track 5 and positioned by the main roller positioning plate to prevent the main roller 6 from moving in series and causing the internal parts to fall.

[0037] In the implementation method, a support rib 1 is provided at the lower part of the support ring 4, and 40 support ribs 1 are evenly distributed along the circumferential direction of the cylinder. The 40 support ribs 1 need to be welded at a fixed angle position. An oblong bolt hole is opened on the support rib 1, and the connection is achieved by bolt cooperation with the positioning clamp 13.

[0038] In this embodiment, a connecting plate II 12 is provided at the bottom of the I-beam 11. Bolt holes are provided on both the connecting plate II 12 and the positioning plate 13. Bolts are used to connect the positioning plate 13 to the I-beam 11. The bottom of the positioning plate 13 is fixedly connected to the supporting rib 1 by bolts I 14 and nuts II 15.

[0039] like Figure 1 、 Figure 2 As shown, there are two main rollers 6, connected to the I-beam 11 via connecting plate I9 and connecting plate I10. The main rollers 6 are mounted on connecting plate I9 via nuts I8, with a clamping plate 7 positioned between the nuts I8 and connecting plate I9. Connecting plate I10 is welded to the center of connecting plate I9. Below the main rollers 6 is a roller track 5, secured to the support ring 4 and connected to the main rollers 6, enabling 360° rotation along the track (along the cylinder). There is one auxiliary roller 17, connected to the I-beam 11 via a positioning plate 19 and connecting plate III 21. Below the auxiliary roller 17 is a support plate 29, allowing 360° rotation along the axis of the support plate 29. During operation, the main rollers 6 and auxiliary rollers 17 are positioned and prevented from moving in unison using main roller positioning plates I2, II3, and 30.

[0040] like Figure 6 、 Figure 7 Shown are details of the main and auxiliary rollers.

[0041] In the main and auxiliary roller implementation, the roller sliding track 5 at the bottom of the main roller 6 is set with an R70 arc, so that the main roller 6 can slide smoothly, and the supporting plate 29 at the bottom of the auxiliary roller 17 is machined to control the surface finish for smooth sliding.

[0042] like Figure 1 、 Figure 8 As shown, one end of the positioning plate 13 is bolted to the supporting rib 1 and the other end is bolted to the connecting plate I 10. The positioning plate 13 is connected to the I-beam 11 and the supporting rib 1, and is slid to the specified required position by the main roller 6 and the auxiliary roller 17 for positioning.

[0043] like Figure 1 、 Figure 2 As shown, the main roller 6 and the auxiliary roller 17 can rotate and slide 360° in the circumferential direction. When sliding to the required position, the main roller 6 is fixed by tightening the bolts through the positioning clamp 13 and the supporting rib 1, and the auxiliary roller 17 is fixed by tightening the screws I 20 so that the gap between the supporting plate 29 and the auxiliary roller 17 is gradually reduced, thereby increasing the friction force.

[0044] Specifically, when the main roller 6 implements a 360° circular sliding mode, it is connected to the I-beam 11 by connecting the vertical plate Ⅰ9 and the connecting plate Ⅰ10, and the auxiliary roller 17 assists. When sliding to the required position, the positioning clamp plate 13 and the support rib plate 1 bolt hole are used to fix it with bolts to prevent the main and auxiliary rollers from continuing to slide along the sliding track again.

[0045] In the mode where the auxiliary roller 17 assists the main roller 6 in sliding 360° around its circumference, the auxiliary roller 17 achieves its sliding and connection to the I-beam 11 through the cooperation of the connecting plate Ⅱ 18, the positioning plate 19, the connecting plate Ⅲ 21, screws, etc., and the auxiliary roller 17 is fixed and positioned by tightening the screws Ⅰ 20 to assist the main roller 6 in being fixed. Specifically, the connecting plate Ⅲ 21 is connected to the upper side of the other side of the I-beam 11 by bolts Ⅱ 22, nuts Ⅲ 23, washers Ⅰ 24, and washers Ⅱ 25. The connecting plate Ⅲ 21 is connected to the connecting plate Ⅱ 18, and the auxiliary roller 17 is installed on the connecting plate Ⅱ 18. The positioning plate 19 is connected to the connecting plate Ⅱ 18. When rotated into place, the positioning plate 19 is connected to the support plate 29 by screws Ⅰ 20. The auxiliary roller positioning plate 30 is set on the support plate 29 and is located between the auxiliary roller 17 and the connecting plate Ⅱ 18.

[0046] like Figure 1 、 Figure 2 As shown, a monorail trolley and a hand chain hoist are provided on the I-beam 11 to move the hoisted internal parts in the transverse direction of the inner diameter of the cylinder. The monorail trolley slides on the I-beam 11 in the direction of the cylinder diameter to achieve transverse movement of the hoisting device.

[0047] like Figure 3 As shown, a baffle 28 is installed on the other side of the I-beam 11, and the baffle 28 is located inside the support tube 16; an angle steel 27 is installed on the lower side of the other side of the I-beam 11 through screws II 26.

[0048] According to the structural diagram of the present utility model, after the internal parts of the pressure vessel enter the equipment, the lateral movement is achieved by the monorail trolley sliding on the I-beam 11, and the 360° circumferential movement is achieved by the main roller 6 and the auxiliary roller 17 on the roller sliding track 5 and the support plate 29 respectively. Through the lateral and circumferential movement, the multifunctional and all-round functions of the lifting device are realized as a whole. During operation, the main roller 6 and the auxiliary roller 17 realize roller positioning, anti-stringing and avoidance of roller derailment and falling of the internal parts through the main roller positioning plate Ⅰ2, the main roller positioning plate Ⅱ3 and the auxiliary roller positioning plate 30.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
