Description

Technical Field

[0001] The present invention relates to the technical field of hoisting, and in particular to an integral cast-in-situ tooling lifting and hoisting device and method. Background Art

[0002] Currently, the deck protection walls and vertical walls of my country's high-speed railway bridges utilize cast-in-place reinforced concrete structures. The shields are prefabricated reinforced concrete structures, connected to the beams using cast-in-place concrete to form an integral structure. Research on the construction and operational status of high-speed railway bridges reveals that traditional bridge deck systems prefabricate and install shields, with the three walls constructed separately. The vertical walls and protection walls have a significant amount of pre-embedded steel reinforcement in the flanges, which conflicts with the longitudinal and transverse reinforcement in the beam flanges. Furthermore, the exposed portions are exposed to the elements for extended periods, making them susceptible to collisions and corrosion from mechanical equipment. This leads to complex processes, tight construction deadlines, difficulty transporting concrete, difficulty controlling construction quality, and high safety risks.

[0003] If the bridge shield, cable trough vertical wall and crash barrier are constructed as one process, the integral molds of the shield, cable trough vertical wall and crash barrier are prefabricated in sections in advance, and then the multiple sections are connected to the bridge and relatively spliced ​​before casting. This can simplify the process and improve construction efficiency. However, since there was no such integral casting mold before, there is no equipment for lifting the integral mold. The overall volume of the integral mold is relatively large. The traditional lifting method is prone to shaking when placing the hoisted casting tooling, which is not convenient for placing it in the correct position for splicing. During splicing, since part of the casting tooling is located outside the beam body, it is currently necessary to use a construction trolley to move the construction personnel to the outside of the bridge to fix the casting tooling and the bridge, which is not convenient to use. Therefore, an integral cast-in-place tooling lifting and hoisting equipment and method are proposed to solve the above problems. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-Figure 2 and Figure 4As shown, an embodiment of the present invention provides an integral cast-in-situ tool lifting and hoisting device, including an electric trolley 1, one end of the electric trolley 1 is connected to the head of the vehicle (not shown in the figure) and can be manually started, a high-strength bracket 2 is fixed on the top of the electric trolley 1, a cross frame 3 is provided on the top of the high-strength bracket 2, and a height-adjustable lifting basket 12 is provided at one end of the cross frame 3. The lifting basket 12 specifically includes a basket body 1201, and ladders 1202 are respectively provided on both sides of the basket body 1201. A guide chute 1203 is connected to one end of the cross frame 3, and the ladder 1202 is in the guide chute. 1203 slides internally, and a hoist 1204 is provided on the surface of one end of the horizontal frame 3. The lifting chain of the hoist 1204 is connected to the connecting plate 1205 fixed on the surface of the ladder 1202. When the hoist 1204 is retracted or extended, it can drive the hanging basket body 1201 to rise or fall as a whole. The operator can enter the interior of the hanging basket body 1201. The lifting hanging basket 12 is moved to the outside of the bridge and suspended in the air, which is convenient for fastening the outer side of the integral cast-in-place tooling 13 to the bridge after the integral cast-in-place tooling 13 is hoisted, thereby facilitating the subsequent integrated casting.

[0028] An electric movable platform 4 is provided on the top of the cross frame 3, and a hoisting and winding mechanism 5 is installed on the upper surface of the electric movable platform 4. A wire rope 6 is provided on the surface of the hoisting and winding mechanism 5, which can be used to hoist the integral cast-in-place tooling 13. After the hoisting is completed, the tooling can be directly connected and fastened to the bridge in conjunction with the lifting basket 12, without the need for an additional construction trolley.

[0029] Specifically, a rack rod 301 is fixed in the middle position of the cross frame 3, a slide groove 302 is provided on the surface of the cross frame 3, and the electric movable platform 4 includes a table top 401 arranged on the surface of the cross frame 3, and a pulley extending to the inside of the slide groove 302 is provided at the bottom of the table top 401. A driving motor 402 is fixed to the top of the table top 401, and a driving gear 403 is fixed to the driving end of the driving motor 402. The driving gear 403 is engaged with the rack rod 301. During specific use, the driving motor 402 is started, and the driving motor 402 can drive the driving gear 403 to rotate, and the driving gear 403 moves on the surface of the rack rod 301, thereby realizing the overall movement of the electric movable platform 4, so that the integral cast-in-place tooling 13 can be hoisted to the edge of the bridge.

[0030] Specifically, the hoisting and winding mechanism 5 includes a winding motor 501, the driving end of the winding motor 501 is connected to a winding roller 502, the outer surface of the winding roller 502 is connected to two winding disks 503, and the surfaces of the two winding disks 503 are both wound with steel wire ropes 6, thereby realizing the winding and lifting of the steel wire ropes 6.

[0031] Example 2

[0032] like Figure 1-Figure 7As shown, since the integral cast-in-place tooling 13 is relatively large in size, it needs to be spliced ​​together as a whole after each section is hoisted. However, during hoisting and docking, the rope shakes and it is difficult to accurately dock the hoisted integral cast-in-place tooling 13 with other integral cast-in-place tooling 13, so further design is carried out.

[0033] The bottom end of the steel wire rope 6 on the surface of the hoisting and winding mechanism 5 is connected with a fine-adjustable hoisting bracket 7, which is used to achieve fine-tuning of the position of the integral cast-in-place tooling 13. The surface of the lifting basket 12 is installed with a positioning component 8, and the surface of the fine-adjustable hoisting bracket 7 is provided with a clamping component 9 that matches the positioning component 8. When the fine-adjustable hoisting bracket 7 moves to the side close to the lifting basket 12, the clamping component 9 is connected with the positioning component 8 to ensure the stability of the hoisting and lifting, and cooperates with the fine-adjustable hoisting bracket 7 to fine-tune the integral cast-in-place tooling 13 when the steel wire rope 6 is stable, so that the integral cast-in-place tooling 13 can be accurately docked with each other to complete the quick splicing operation.

[0034] Specifically, the fine-adjustable lifting bracket 7 includes a top frame 701, the interior of the top frame 701 is slidably connected to a transverse plate 702, a transverse cylinder 703 is connected between the top frame 701 and the transverse plate 702, the bottom of the transverse plate 702 is slidably connected to a longitudinal plate 704, a longitudinal cylinder 705 is installed on the lower surface of the transverse plate 702, the telescopic end of the longitudinal cylinder 705 is connected to the longitudinal plate 704, and a group of hooks 706 are respectively provided at both ends of the longitudinal plate 704, each group of hooks 706 has two, and the hooks 706 are arranged in an L shape, which can evenly hook the integral cast-in-place tooling 13 with force for lifting.

[0035] The locating slot 902 of the card plate 901 is provided with an arc edge, and the two symmetrical side walls of the locating slot 902 are provided with a telescopic card block 903, which matches the positioning slot of the locating assembly 8. The telescopic card block 903 includes a spring and a card block. One end of the card block near the vertical rod is provided with an arc surface. When in use, the fine-adjustable lifting bracket 7 is first moved to the edge of the bridge with the card connecting assembly 9. At this time, due to the high lifting height and the short wire rope 6, the movement is relatively stable. In addition, due to the setting of the arc edge at the positioning slot 902 of the card plate 901, the card plate 901 can be stuck on the surface of the vertical rod of the positioning assembly 8 during the movement, that is, Figure 7As shown, since the weight of the integral cast-in-place tooling 13 is sufficient, when the vertical rod is inserted into the interior of the positioning port 902, the telescopic block 903 can be directly inserted into the interior of the positioning slot under the action of pressure, thereby achieving positioning, so that the hoisted integral cast-in-place tooling 13 can stably lower the vertical rod, and at the same time facilitate fine-tuning of the position of the integral cast-in-place tooling 13. The entire equipment is made of high-strength steel, which can avoid deformation with the integral cast-in-place tooling 13.

[0036] Example 3

[0037] like Figures 1-9 As shown, in order to facilitate the operator to perform the tightening operation of the integral cast-in-place tooling 13 outside the bridge, the device itself is provided with a lifting basket 12 with a certain weight. When the integral cast-in-place tooling 13 is hoisted to the edge of the bridge, the weight of the end is further increased when it is close to the side of the lifting basket 12. In order to ensure stability during hoisting, the equipment is further designed.

[0038] A linkage assembly 10 is provided on both sides of the cross frame 3, and a counterweight assembly 11 is installed at the bottom of the linkage assembly 10. When the electric movable platform 4 hoists the integral cast-in-place tooling 13 and moves to the side close to the lifting basket 12, the linkage assembly 10 drives the counterweight assembly 11 to move to the end away from the integral cast-in-place tooling 13. The linkage assembly 10 includes a bracket 1001 fixed on the outer wall of the cross frame 3, and a sliding rod 1002 is installed on the inner wall of the bracket 1001. The outer surface of the sliding rod 1002 is slidably connected with a slide plate 1003. The top of the slide plate 1003 is provided with a first bar tooth 1004, and the side wall of the cross frame 3 is provided with a linkage gear 1005. The lower surfaces of both ends of the table 401 are provided with a second bar tooth 1006. The linkage gear 1005, the first bar tooth 1004 and the second bar tooth 1006 are meshed. Therefore, when the table 401 moves, the first bar tooth 1004 will be driven to move in a linkage manner, thereby Drive the counterweight assembly 11 to move. When the counterweight assembly 11 moves to a section of the cross frame 3 away from the lifting basket 12, the second bar tooth 1006 disengages from the linkage gear 1005, and the table top 401 will continue to move until the edge of the bridge. This is because the counterweight assembly 11 moves to the other end, so it will produce a corresponding balance with the hoisted integral cast-in-place tooling 13, ensuring the overall stability of the device. When the electric moving platform 4 is reset as a whole, it will drive the counterweight assembly 11 back to the middle position of the high-strength bracket 2. Since the electric trolley 1 has an overall increase in the counterweight assembly 11, the weight of its lifting basket 12 will not cause the overall overturning of the device when it is not hoisted. The required counterweight weight is calculated according to the weight of the hoisted object × the distance from the hoisted object to the fulcrum + other load torque = counterweight × the distance from the counterweight to the fulcrum. In this way, there is no need to add excessive counterweight on the top of the electric trolley to meet the stability during hoisting.

[0039] Example 4

[0040] like Figures 1-9 As shown, the currently designed integral cast-in-place tooling 13 includes the following specific structures:

[0041] It includes a combined steel formwork and a door frame 1309. The combined steel formwork includes a side wall curved panel 1301, a side wall side panel 1302, two vertical wall side panels 1303, a protective wall inclined panel 1304 and a protective wall vertical panel 1305. The combined steel formwork and the door frame 1309 are connected by turnbuckle screws 1306 and precision-rolled threaded steel 1307. The bottom of the door frame 1309 is also provided with an adjustable square tube 1308 for support.

[0042] A side wall casting area is formed between the side wall curved panel 1301 and the side wall side panel 1302, a vertical wall casting area is formed between the two vertical wall side panels 1303, a protective wall casting area is formed between the protective wall inclined plate 1304 and the protective wall vertical panel 1305, and cable troughs are formed on both sides of the vertical wall casting area. The bottom end of the side wall curved panel 1301 adopts a U-shaped design to facilitate the connection of the bottom end of the side wall curved panel 1301 with the flange plate of the bridge.

[0043] Among them, the hoisting method of the integral cast-in-place tooling includes the following specific operating steps:

[0044] S1. Move the equipment to the edge of the bridge, hook the two ends of the portal frame 1309 of the integral cast-in-place tooling 13 with the hook 706, and then start the hoisting and winding mechanism 5 to lift the integral cast-in-place tooling 13;

[0045] S2, the electric moving platform 4 moves the integral cast-in-place tooling 13 to the edge of the bridge. During the movement, the counterweight assembly 11 is driven to move to the side away from the lifting basket 12;

[0046] S3. After the integral cast-in-place tooling 13 is hoisted to the edge of the bridge, the clamping assembly 9 is connected to the positioning assembly 8, so that the integral cast-in-place tooling 13 can be lowered in stability. After it is lowered to a specific position, the position of the integral cast-in-place tooling 13 is finely adjusted by the fine-adjustable hoisting bracket 7, so that the integral cast-in-place tooling 13 can be docked with other integral cast-in-place tooling 13, and at the same time, the bottom end of the curved side wall panel 1301 of the integral cast-in-place tooling 13 is brought into contact with the flange plate of the bridge;

[0047] S4. After the hoisting is completed, the fine-adjustable hoisting bracket 7 is moved upward so that the clamping assembly 9 is moved out from the top of the positioning assembly 8 and separated from the positioning assembly 8. Then, the electric moving platform 4 can be reset.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
