Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically relating to an I-beam transfer device for arch frame operations. Background Technology

[0002] I-beams, as primary load-bearing components, are widely used to transfer and distribute various loads borne by the arch frame, ensuring the stability and safety of the arch structure. The cross-sectional shape of I-beams gives them excellent bending and torsional resistance, effectively increasing the stability of the arch structure and preventing excessive deformation or instability under load. Furthermore, I-beams are easy to cut, weld, and assemble, making the installation and processing in arch construction relatively simple and quick, improving construction efficiency, and reducing construction difficulty and costs. Patent CN213202151U discloses a hoisting device for H-beams in construction engineering, comprising a base, vertical shaft, horizontal arm, cylinder, lifting hydraulic cylinder, and rail-type strips. In use, the extension of the piston rod of the lifting hydraulic cylinder moves the rail-type strips and slide downwards, bringing them into contact with the upper surface of the H-beam. The optimal lifting point is calculated based on the length of the H-beam, and a traveling device moves the slide along the rail-type strips. When the slide reaches the designated point, a control switch shortens the piston rod of the hydraulic cylinder. This shortens the piston rod, pulling a push block towards the hydraulic cylinder. The movable rod causes two L-shaped clamping plates to move closer together, and the sliding column moves into the inner end of the circular sliding hole until the two L-shaped clamping plates and the lower surface of the rail-type strip clamp the upper end of the H-beam. Then, the piston rod of the lifting hydraulic cylinder shortens, thus lifting the H-beam. The L-shaped clamps and rail-type strips provided by the above technical solution can only provide preliminary clamping for lifting of the I-beams. In actual use, after transporting the I-beams to the designated location, the construction personnel still need to remove the I-beams from the lifting device for subsequent splicing, which is inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an I-beam transfer device for arch frame operations.

[0004] The technical approach adopted in this utility model is as follows: This utility model provides an I-beam transfer device for arch frame operation. The I-beam transfer device includes a transfer device body and a clamp connected to the transfer device body. The clamp includes a telescopic platform and a primary gripper and a secondary gripper set on the telescopic platform. The primary gripper and the secondary gripper are both connected to the telescopic platform through hydraulic rods. During use, the upper flange of the I-beam can be lifted and fixed upwards using the primary gripper, and the lower flange can be pressed and fixed downwards using the secondary gripper, thus achieving overall fixation of the I-beam. Then, the I-beam can be directly spliced ​​by moving it to the splicing position using the transfer device body. The I-beam remains stable throughout the splicing process, eliminating the need for construction personnel to unload the I-beam from the transfer device body before splicing, simplifying the construction steps and making it convenient to use.

[0005] Based on the above technical concept, the technical solution adopted by this utility model is as follows: A transfer device for I-beams used in arch frame construction includes a transfer device body, on which a clamp for fixing the I-beams is provided; the clamp includes: The telescopic platform is connected to the main body of the transfer device; The primary gripper is located above the telescopic platform and is connected to the telescopic platform via the first hydraulic rod. The secondary gripper is located between the primary gripper and the telescopic platform, and is connected to the telescopic platform via a second hydraulic rod.

[0006] Further specifying the above technical solution, preferably, both the primary gripper and the secondary gripper are three-segment structures.

[0007] In order to achieve both close contact with the upper flange of the curved I-beam and fit snugly against the tunnel wall for precise I-beam splicing, the above technical solution is further defined as follows: the upper surface of the primary gripper is curved, and the lower surface is flat.

[0008] Similarly, in order to ensure close contact between the lower flange plate of the curved I-beam, the above technical solution is further defined by making the upper surface of the secondary gripper flat and the lower surface curved.

[0009] To further define the above technical solution for securing I-beams of different specifications, the telescopic platform includes: First Activities Department; The second movable part is connected to the first movable part via a transverse hydraulic rod; The rotating shaft is connected to the lugs located on the sides of the first and second movable parts, and is also connected to the main body of the transfer device.

[0010] To ensure the proper use of the clamp, the above technical solution is further refined by connecting the rotating shaft to the lug via a telescopic rod. Beneficial effects

[0011] I. This utility model, through the combined design of a telescopic platform, a primary gripper, and a secondary gripper, can firmly fix the two flanges of the I-beam, so that the main body of the transfer device can directly move the I-beam to the splicing position for splicing, without having to remove the I-beam, simplifying the construction steps and making it convenient to use.

[0012] Second, both the primary gripper and the secondary gripper provided by this utility model have a three-section structure, resulting in low manufacturing costs.

[0013] Third, the upper surface of the primary gripper provided by this utility model is curved, so that the upper surface of the primary gripper can better fit with the surface of the upper flange plate of the curved I-beam, thereby making the curved I-beam fit with the tunnel wall; similarly, the lower surface of the secondary gripper is curved, so that the secondary gripper can better fit with the surface of the lower steel flange plate of the curved I-beam; in this way, both the upper and lower surfaces of the curved I-beam can be fixed, so as to facilitate the precise splicing of the subsequent steel beams.

[0014] Fourth, in addition to splicing I-beams, the clamp provided by this utility model can also be used for disassembling or replacing I-beams. The first-level gripper with an arched structure can fit more closely to the connection point of the deformed arch frame section, so as to accurately splice the I-beams. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] The inventors discovered that currently, after transporting I-beams, users need to unload them from the transport device before splicing them together, which is very inconvenient.

[0022] Based on the above findings, this application proposes an I-beam transfer device for arch frame operations, comprising: a telescopic platform 1, a primary gripper 2, a secondary gripper 3, and a transfer device body 4. This application achieves better overall device performance and higher construction efficiency through the following design: 1. The combined design of telescopic platform 1, primary gripper 2 and secondary gripper 3 is used to firmly fix the I-beam 7 as a whole. In this way, the main body of the transfer device 4 can directly move the I-beam 7 to the splicing position for splicing without having to remove the I-beam 7, which simplifies the construction steps and makes it convenient to use. 2. The primary and secondary grippers provided in this application are both three-section structures, resulting in low manufacturing costs; 3. The upper surface of the primary gripper provided in this application is curved, and the lower surface is flat. In this way, the upper surface of the primary gripper can better fit against the tunnel wall, and the lower surface is flat so as to fit tightly against the flange plate of the I-beam 7, fixing the I-beam 7 so as to facilitate the precise splicing of the I-beam 7 in the future. In addition, the clamping device provided in this application can also be used to replace deformed I-beam 7. The arched structure of the primary gripper can fit more closely against the deformed arch frame connection point so as to facilitate the precise splicing of the I-beam 7.

[0023] It should be noted that the I-beam transfer device provided in this embodiment of the present invention is suitable for arch frame operations, and is especially suitable for splicing I-beams with arc-shaped structures in tunnel arch frame operations.

[0024] Example 1 like Figures 1 to 5 As shown, the present invention provides an I-beam 7 transfer device for arch frame operation, including a telescopic platform 1, a primary gripper 2, a secondary gripper 3, a transfer device body 4, a first hydraulic rod 5, and a second hydraulic rod 6.

[0025] like Figure 1 and Figure 4 As shown, the telescopic platform 1 includes a first movable part 11, a second movable part 12, a rotating shaft 13, a hanging lug 14, a transverse hydraulic rod 15, and a telescopic rod 16.

[0026] The first movable part 11 and the second movable part 12 have the same structure, both being plate-shaped structures. Specifically, the first movable part 11 is fixedly connected to the second movable part 12 via a transverse hydraulic rod 15. Each of the first movable part 11 and the second movable part 12 is provided with a hanging ear 14 on its outer side, and each hanging ear 14 is fixedly connected to the side of the rotating shaft 13 via a telescopic rod 16.

[0027] In practical use, the rotating shaft 13 is connected to the output end of the transfer device body 4. It should be noted that the transfer device body 4 provided in this embodiment is prior art, and this embodiment does not improve upon it. For example, the transfer device body 4 is specifically a robotic arm.

[0028] The primary gripper 2 and the secondary gripper 3 are three-section structures, each including three clamping units. Each clamping unit includes two clamping blocks, which are symmetrically arranged on the first movable part 11 and the second movable part 12, respectively. Specifically, the upper surface of the clamping block of each of the three clamping units of the primary gripper 2 is curved and the lower surface is flat. The upper surface of the three clamping units of the primary gripper 2 is a continuous curved surface. In this way, the upper surface of the clamping unit of the primary gripper 2 can better fit with the flange of the I-beam 7, thereby making the I-beam 7 fit with the tunnel wall. Each clamping block of the three clamping units of the primary gripper 2 is fixedly connected to the telescopic platform 1 through the first hydraulic rod 5.

[0029] The upper surface of the clamping block of each of the three clamping units of the secondary gripper 3 is a flat surface and the lower surface is an arc surface. The lower surface of the three clamping units of the secondary gripper 3 is a continuous arc surface. In this way, the lower surface of the secondary gripper 3 can better fit with the bottom surface of the I-beam 7 so as to fix the I-beam 7.

[0030] It should be noted that the transverse hydraulic rod 15, the first hydraulic rod 5, the second hydraulic rod 6 and the telescopic rod 16 provided in this embodiment of the present invention are all prior art, and this embodiment of the present invention does not make any improvements to them.

[0031] Implementation Cases Step 1: Connect the rotating shaft 13 to the output end of the transfer device body 4; Step 2: Place the I-beam 7 at the center of the telescopic platform 1; Step 3: Activate the transverse hydraulic rod 15 to make the sides of the primary gripper 2 and the secondary gripper 3 in close contact with the web of the I-beam 7; Step 4: Increase the height of the first hydraulic rod 5 and the second hydraulic rod 6 so that the first-stage gripper 2 is in close contact with the bottom surface of the upper flange plate of the I-beam 7, and the second-stage gripper 3 is in close contact with the upper surface of the lower flange plate of the I-beam 7, thereby achieving the clamping and fixing of the I-beam 7. In this step, the telescopic rod 16 extends or retracts as the lug 14 moves; Step 5: Start the transfer device body 4. After rotating the device body 4, the clamping device moves to the splicing position. Then, the telescopic platform 1 is rotated through the rotating shaft 13 to adjust the angle of the I-beam 7 so that the I-beam 7 can be accurately spliced ​​in the future. Step 6: Splice the I-beams into 7 sections.

[0032] After the splicing is completed, the first-level gripper 2 and the second-level gripper 3 are separated from the I-beam 7 by the horizontal hydraulic rod 15, the first hydraulic rod 5 and the second hydraulic rod 6, and then the clamping device is taken out from under the I-beam 7 so that the next I-beam 7 can be spliced.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
