Description

Technical Field

[0001] This invention belongs to the field of tire frame technology, specifically relating to a tire frame rapid lifting device. Background Technology

[0002] A jig is a type of tooling primarily used to support the weight of structural components. It is a specialized piece of equipment designed to facilitate the welding and assembly of large mechanical equipment, and is widely used in steel structure installation, bridge engineering, and formwork engineering. Different equipment employs different processes, and therefore, the corresponding jig types also vary.

[0003] When installing components at heights (such as bridge structural parts), it is necessary to assemble a jig of the corresponding height for support. In existing technology, jig assembly usually uses a crane to connect the jig standard parts to the ground jig in stages at high altitude, and workers then install and fix the jig standard parts at the connection points. Because it is difficult to connect the jig standard parts lifted by the crane to the ground jig, and workers need to perform installation and fixing operations on platforms at different heights one by one, there is a lack of operational safety, resulting in high difficulty and low efficiency in jig lifting and assembly operations.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a rapid lifting device for the tire frame.

[0037] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0038] like Figures 1-10 As shown, in one embodiment of the present invention, a rapid lifting device for a jig frame is provided. The jig frame is composed of several jig frame standard parts 10, wherein the jig frame standard parts 10 are generally assembled by welding uprights, crossbeams and diagonal beams.

[0039] The rapid lifting equipment includes an auxiliary frame 20, a crane 30, and a platform 40. A lifting winch 31 is installed on the crane 30, and a top plate is fixedly installed on the uppermost first set of jig standard components 10. The lifting winch 31 is connected to the top plate on the uppermost first set of jig standard components 10 via a steel wire rope. The lifting winch 31 can lift all jig standard components 10 assembled with the uppermost first set of jig standard components 10 via the steel wire rope.

[0040] The platform 40 is located inside the auxiliary frame 20 and is used to support the jig standard parts 10 to be assembled. The platform 40 is equipped with a four-corner positioning assembly, which includes four sets of grooves (not shown in the figure) formed on the upper surface of the platform 40. Flanges are installed at both ends of the four uprights of the jig standard parts 10 for assembling and fixing adjacent jig standard parts 10. The four sets of grooves correspond to the flanges on the four sets of uprights.

[0041] Specifically, when placing the standard component 10 of the jig on the platform 40, the standard component 10 of the jig can be accurately positioned on the platform 40 by inserting the flanges at the bottom of the four columns into the four sets of grooves respectively.

[0042] like Figures 1-2 As shown, a pair of base plates 50 are fixedly installed at the bottom of the auxiliary frame 20. A travel rail 51 is provided on the base plate 50. An electric travel wheel 41 is installed below the platform 40. The electric travel wheel 41 is driven by a motor and can move automatically. The electric travel wheel 41 is tactilely connected to the inside of the travel rail 51. By rolling the electric travel wheel 41 inside the travel rail 51, the platform 40 can move on the base plate 50.

[0043] The auxiliary frame 20 has a C-shaped cross-section, and one end of the base plate 50 extends to the outside of the auxiliary frame 20. The length of the base plate 50 extending to the outside of the auxiliary frame 20 is greater than the length of the platform 40. In other words, the platform 40 can be completely removed from the inside of the auxiliary frame 20 on the base plate 50, making it convenient to place the jig standard part 10 to be assembled on the platform 40.

[0044] Specifically, the platform 40 is automatically moved out of the auxiliary frame 20 on the base plate 50, allowing the standard component 10 of the jig to be assembled to be received in a place with sufficient space outside the auxiliary frame 20. Then, the platform 40 is moved to transfer the standard component 10 of the jig to be assembled to the inside of the auxiliary frame 20 for subsequent assembly work, making construction more convenient.

[0045] A pair of lifting mechanisms are installed on the auxiliary frame 20. The pair of lifting mechanisms are used to lift the standard component 10 of the jig on the platform 40 to achieve docking with the standard component 10 of the jig above. At the same time, it can help lift the assembled jig as a whole, making the jig lifting more stable and efficient.

[0046] like Figures 2-4 As shown, the lifting mechanism includes a pair of lifting slots 21 on opposite sides of the auxiliary frame 20. The lifting frame 22 is slidably connected inside the pair of lifting slots 21. A pair of lifting winches 23 are also fixedly installed on the auxiliary frame 20. The lifting winches 23 are connected to the lifting frame 22 by steel wire ropes. The lifting winches 23 can lift the lifting frame 22 by steel wire ropes, so as to realize the sliding lifting of the lifting frame 22 inside the lifting slots 21.

[0047] Among them, such as Figure 4 and Figure 7 As shown, multiple sets of rollers 221 are rotatably connected to both sides of the lifting frame 22. An inner rail 211 matching the rollers 221 is provided on the lifting groove 21. When the lifting frame 22 slides and rises inside the lifting groove 21, the rollers 221 will roll inside the inner rail 211, thereby effectively reducing the frictional resistance of the lifting frame 22 inside the lifting groove 21, making the lifting of the auxiliary frame 20 more effortless and preventing jamming.

[0048] The lifting frame 22 is L-shaped. After the platform 40 moves into the auxiliary frame 20, one end of each pair of L-shaped lifting frames 22 is located below the platform 40. By lifting the lifting frame 22, the platform 40 can be lifted upward, allowing the jig standard component 10 on the platform 40 to rise and dock with the jig standard component 10 above.

[0049] like Figure 1 As shown, the base plate 50 has a break, and one end of the lifting frame 22 is located inside the break. That is, one end of the lifting frame 22 can be hidden inside the break in the base plate 50, becoming part of the base plate 50. The lifting frame 22 has a through groove 222 that matches the traveling rail 51. When the electric traveling wheel 41 at the bottom of the platform 40 travels inside the traveling rail 51, it will pass through the inside of the through groove 222, ensuring that the platform 40 can smoothly enter the interior of the auxiliary frame 20.

[0050] Specifically, when the platform 40 containing the jig standard component 10 moves into the auxiliary frame 20, the lifting frame 22 is positioned directly below the middle of the platform 40. At this time, the lifting winch 23 lifts the lifting frame 22, which in turn lifts the platform 40 from the bottom upwards, causing the platform 40 to rise until the jig standard component 10 on the platform 40 is aligned with the jig standard component 10 above it. That is, the flanges on the uprights of the two sets of jig standard components 10 are aligned together. Finally, the flanges are locked and secured with bolts and nuts in sequence, thus completing the assembly of the jig standard component 10 from below.

[0051] In this way, by lifting the already assembled jig frame step by step with the hoist 31, and then assembling the jig frame standard parts 10 step by step from the bottom, compared with lifting the jig frame standard parts 10 step by step with the hoist 31, the jig frame standard parts 10 can be connected in one go during the connection process, without the need to adjust the position of the jig frame standard parts 10 at high altitude, which greatly reduces the assembly difficulty.

[0052] Secondly, the installation and fixing work can be completed by the staff on the ground after docking, which not only avoids working at height and improves the safety of workers, but also eliminates the need to frequently change the work position according to the assembly height, effectively reducing the construction difficulty and shortening the construction time.

[0053] This rapid lifting equipment can effectively shorten the assembly time of the jig, greatly improve work efficiency, reduce the assembly difficulty of the jig, and thus enable the jig of the required height to be assembled quickly and safely, shortening the project cycle.

[0054] like Figure 2 , Figure 5 and Figure 6 As shown, a pair of clearance support structures are installed inside the auxiliary frame 20. The pair of clearance support structures includes a pair of fixed seats 60. The pair of fixed seats 60 are fixed on opposite sides inside the auxiliary frame 20. Each pair of fixed seats 60 is slidably connected to a support block 61 that can be elastically extended and retracted. The pair of support blocks 61 are used to support the jig frame that is lifted by the hoisting winch 31.

[0055] Specifically, if the pre-assembled jig is suspended solely by the lifting winch 31, it is highly prone to swaying and exhibits significant instability. In this case, the jig can be supported by two sets of support blocks 61. The support blocks 61, combined with the lifting action of the lifting winch 31, ensure that the jig does not sway or tilt. This not only facilitates stable assembly of the jig but also reduces the possibility of accidents and protects the safety of workers.

[0056] Among them, such as Figure 8 As shown, a positioning groove 611 is provided on the support block 61. The positioning groove 611 matches the crossbeam on the standard part 10 of the tire frame. By placing the crossbeam on the standard part 10 of the tire frame inside the positioning groove 611, the crossbeam can be effectively limited. This can effectively prevent the tire frame from sliding relative to the pair of support blocks 61, and improve the stability of the pair of support blocks 61 supporting the tire frame.

[0057] It is worth noting that, in order to ensure that the tire frame does not slide relative to the pair of support blocks 61, a set of fixed seats 60 and support blocks 61 with the same structure can be added to the rear end inside the auxiliary frame 20. In this way, the three sets of support blocks 61 form a multi-directional support and limiting effect on the tire frame, which can effectively prevent the tire frame from sliding relative to the other and achieve higher stability.

[0058] The fixed base 60 has a sliding groove, and a spring 62 is fixedly connected inside the sliding groove. One end of the support block 61 is inserted into the sliding groove and fixedly connected to the spring 62. The spring 62 allows the support block 61 to slide and extend within the sliding groove on the fixed base 60.

[0059] The lower end face of the support block 61 adopts a sloping back structure. During the lifting process of the jig frame, when any part of it comes into contact with the lower end face of the support block 61 during the upward process, the sloping back structure can push the support block 61 into the sliding groove on the fixed seat 60.

[0060] Specifically, such as Figure 9 and Figure 10 As shown, after the standard parts 10 of the jig frame are connected and fixed from the bottom, the lifting winch 31 lifts the jig frame upward while the lifting winch 23 continues to lift the lifting frame 22 upward, so that the lifting frame 22 lifts the jig frame upward. Thus, the jig frame is lifted by a combination of lifting and supporting, which is more stable and efficient.

[0061] When the tire frame is rising, any part of it will contact the lower end face of the support block 61 and push the support block 61 to retract into the sliding groove, so that the support block 61 will automatically retract and avoid obstructing the lifting of the tire frame, thus ensuring that the tire frame can be lifted smoothly at any time.

[0062] In use, after the platform 40 is moved out of the auxiliary frame 20 on the base plate 50, the standard component 10 of the jig to be assembled is placed on the platform 40. Then, the platform 40 returns to the auxiliary frame 20, and the positioning of the standard component 10 of the jig to be assembled on the platform 40 is checked to ensure accuracy. Next, the lifting frame 22 is lifted by the lifting winch 23. The lifting frame 22 lifts the platform 40 from the bottom upwards, causing the platform 40 to rise until the standard component 10 of the jig on the platform 40 is aligned with the standard component 10 of the jig above it. That is, the flanges on the columns of the two sets of standard components 10 are aligned together. Finally, the flanges are locked and fixed with bolts and nuts in sequence, and the assembly of the standard component 10 of the jig is completed from below.

[0063] After assembling a set of standard jig components 10 from the bottom, the lifting winch 31 is activated to pull the jig upwards, while the lifting winch 23 continues to pull the lifting frame 22 upwards, causing the lifting frame 22 to lift the jig upwards. This combination of lifting and supporting raises the jig until the upper crossbeam on the lowest jig crosses the support block 61. Then, the lifting winch 31 and the lifting winch 23 simultaneously reverse slightly, causing the jig to descend slightly and be placed on the support block 61. The lifting frame 22 can then be reset to allow for the assembly of the next set of standard jig components 10, until the jig of the required height is assembled.

[0064] The rapid lifting device for the jig frame of the present invention changes the original jig frame docking method, changing the original high-altitude lifting docking of the jig frame standard parts 10 to docking the jig frame standard parts 10 step by step from the ground, which effectively reduces the docking difficulty of the jig frame standard parts 10, improves the assembly efficiency of the jig frame, and allows workers to perform the installation and fixing work of the jig frame standard parts 10 after docking on the ground, ensuring work safety.

[0065] The lifting mechanism can lift the standard component 10 of the jig from the ground for docking, saving time and effort. Furthermore, by combining lifting and hoisting, the jig that has been assembled above can be lifted quickly and smoothly, enabling the jig to be assembled safely and efficiently.

[0066] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
