[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0064] Embodiments of the utility model will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the utility model, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used in all drawings to represent the same or similar parts. In addition, although the terms used in the utility model are selected from well-known and commonly used terms, some of the terms mentioned in the utility model specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description herein. In addition, it is required to understand the utility model not only by the actual terms used, but also by the meaning implied by each term.

[0065] like Figure 2a to Figure 2d and Figure 4 As shown, the utility model provides a semi-circular arc beam transfer device, the semi-circular arc beam transfer device comprises a transfer tool 100, the transfer tool 100 comprises a base plate 110, a transfer support base 120, an anti-overturning support 130 and a fixing lug 140,

[0066] The transfer support base 120 is connected to the base plate 110 and is disposed in the middle of the base plate 110 to bear the weight of the semicircular arc beam 300;

[0067] The anti-overturning support 130 is connected to the base plate 110 and is arranged on both sides of the transfer support base 120;

[0068] The fixing lug 140 is mounted on the semicircular arc beam 300 , and the fixing lug 140 is flexibly connected to the anti-overturning support 130 .

[0069] The transfer support base 120 is mainly used to bear the weight of the semi-circular arc beam structure.

[0070] The anti-overturning support 130 is mainly used to ensure the stability of the beam during transportation, thereby further improving the safety of transportation.

[0071] The semicircular arc beam 300 is flexibly connected to the anti-overturning support 130 through the fixed lifting lug 140. The flexible connection method can use a steel wire rope 141, a nylon rope and other components to connect the fixed lifting lug 140 and the anti-overturning support 130. After each transfer, the transfer tooling 100 can be hung at the bottom of the beam. When the beam is transferred to the sandblasting and painting workshop, a certain distance is left between the tooling and the beam to meet the sandblasting and painting of the entire beam, avoiding the subsequent paint repair problem caused by the tooling area being blocked.

[0072] The base plate 110 is arranged at the bottom of the transfer tooling 100, and is preferably a whole steel plate. The base plate 110 can directly contact the flatbed truck 400. The transfer tooling 100 can be designed at multiple positions according to the length of the semi-circular arc beam 300 to ensure the safety of the semi-circular arc beam 300 during transportation.

[0073] After the semi-circular arc beam 300 is manufactured in the workshop, it is hoisted onto the transfer flatbed truck together with the transfer tooling 100 by the workshop crane. After being placed stably, the semi-circular arc beam 300 is transferred to the required work station by the flatbed truck 400.

[0074] The semicircular arc beam transfer device of the utility model is simple, light, convenient and practical.

[0075] like Figure 3a to Figure 3c , Figure 5 and Figure 6 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the semi-circular arc beam transfer device also includes a tire frame placing tool 200, and the tire frame placing tool 200 includes a tire frame 210 and a placing base 220, and the placing base 220 is installed on the tire frame 210.

[0076] After the semi-circular arc beam 300 is transferred to the work station, the tire frame 210 is arranged at the bottom of the semi-circular arc beam 300, and the placement base 220 is arranged on the tire frame 210, and the beam is stably placed on the tire frame placement tool 200 through the flatbed truck 400.

[0077] like Figure 2a to Figure 2d and Figure 4 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the transfer support base 120 includes a first support portion 121 and a second support portion 122 symmetrically arranged, and the first support portion 121 and the second support portion 122 support the semi-circular arc beam 300 by contacting the arc surface of the semi-circular arc beam 300.

[0078] Since there is no partition in the middle area of ​​the bottom of the semi-circular arc beam 300, the transfer support base 120 is designed with a hollow structure in the middle, and the force-bearing positions are the first support part 121 and the second support part 122 on both sides, so as to ensure that the force is smoothly transferred to the beam partition to avoid deformation of the semi-circular arc beam structure. Figure 2d As shown, there is a gap D between the middle position of the transfer support base 120 and the semi-circular arc beam 300.

[0079] like Figure 4 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, a reinforcing structure 123 is provided between the first supporting portion 121 and the second supporting portion 122 .

[0080] like Figure 4 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the anti-overturning support 130 includes a first support 131 and a second support 132 which are symmetrically arranged, and the first support 131 and the second support 132 are arranged on both sides of the transfer support base 120.

[0081] like Figure 2a to Figure 2d and Figure 4 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, sleepers 133 or wooden boards are arranged on the first support 131 and the second support 132 .

[0082] The first support 131 and the second support 132 on both sides of the transfer tooling 100 are mainly used to ensure the stability of the semi-circular arc beam 300 during transfer, thereby further improving the safety of transfer. During design, a gap is reserved with the web 320 of the semi-circular arc beam 300 to ensure that the semi-circular arc beam 300 is completely placed on the transfer support base 120. Then, sleepers 133 or wooden boards can be added between the anti-overturning support 130 and the web 320 according to the actual gap. In this way, the applicability of the transfer tooling 100 in various sections can be guaranteed, thereby avoiding the situation where the transfer tooling 100 cannot be used due to deviation in cross-sectional dimensions.

[0083] like Figure 2a to Figure 2d As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the fixed lifting lug 140 is flexibly connected to the anti-overturning support 130 through a steel wire rope 141.

[0084] In order to improve production efficiency and avoid repeated disassembly and installation of the tooling, during the design, lifting ears are arranged on the web 320 of the semi-circular arc beam 300 and the transfer tooling 100, that is, the anti-overturning support 130 of the transfer tooling 100 is also preferably provided with a lifting ear structure, and the transfer tooling 100 and the semi-circular arc beam 300 are flexibly connected by a steel wire rope 141 and a shackle. The length of the connecting steel wire rope 141 is theoretically lengthened by about 200 mm. After each transfer, the transfer tooling 100 is directly suspended at the bottom of the semi-circular arc beam 300. When the semi-circular arc beam 300 is transferred to the sandblasting and painting workshop for operation, a distance of about 200 mm is left between the transfer tooling 100 and the semi-circular arc beam 300, which can meet the overall sandblasting and painting of the semi-circular arc beam 300 and avoid the subsequent paint repair problem caused by the obstruction of the transfer tooling 100 area.

[0085] like Figure 5 and Figure 6 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the tire frame 210 includes a tire frame body 211 and a tire frame support leg 213. The tire frame body 211 is a cylinder. The top of the tire frame body 211 has a resting plane 212, and the resting base 220 is installed on the resting plane 212; the tire frame support leg 213 is connected to the bottom of the tire frame body 211, and supports the tire frame body 211 from the bottom.

[0086] Preferably, the resting base 220 is consistent in form with the transfer support base 120 in the middle of the transfer tooling 100 .

[0087] like Figure 3a to Figure 3c , Figure 5 and Figure 6 As shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, the placing base 220 includes a third support portion 221 and a fourth support portion 222 which are symmetrically arranged. The third support portion 221 and the fourth support portion 222 support the semi-circular arc beam 300 by contacting the arc surface of the semi-circular arc beam 300.

[0088] Since there is no partition in the middle area of ​​the bottom of the semi-circular arc beam 300, the shelf base 220 is designed with a hollow structure in the middle, and the force-bearing positions are the third support part 221 and the fourth support part 222 on both sides to ensure that the force is smoothly transmitted to the partition of the semi-circular arc beam 300 to avoid deformation of the semi-circular arc beam structure. Figure 3c As shown, there is a gap D between the middle of the placement base 220 and the semi-circular arc beam 300 .

[0089] like Figure 3a to Figure 3cAs shown, as a preferred embodiment of the semi-circular arc beam transfer device of the utility model, jacks 223 are also arranged on both sides of the placement base 220, and a jacking support 224 is installed on the semi-circular arc beam 300, and the jacks 223 cooperate with the jacking support 224 to lift the semi-circular arc beam 300.

[0090] Preferably, a jacking support 224 is provided on the web 320 of the semi-circular arc beam 300 at the tire frame placement position. After the semi-circular arc beam 300 is transferred to the position, the tire frame 210 is arranged in line with the partition position, and a placement tool is arranged on the tire frame 210 to ensure that the semi-circular arc beam 300 is placed stably. At the same time, the jacks 223 on both sides support the jacking support 224 on the web 320 of the semi-circular arc beam 300 to prevent overturning.

[0091] like Figure 1a to Figure 1c The figure shows the structure of the semi-circular arc beam of the shore container crane, wherein the upper wing plate 310 is a plane, the trolley tracks are arranged on both sides of the upper wing plate 310, the web 320 is an arc surface, and the semi-circular arc beam 300 also includes structures such as partitions 330 and reinforcing ribs 340.

[0092] The semi-circular arc beam transfer device of the utility model is a special device designed for the semi-circular arc beam transfer scheme, and the design and use method are as follows:

[0093] According to the size of the arc surface of the semi-circular arc beam 300, a special transfer tool 100 and a tire frame placement tool 200 are made. The transfer tool 100 has fixed ears 140 at both ends to facilitate the fixed connection with the beam.

[0094] After the semi-circular arc beam 300 is manufactured in the workshop, the fixing lug 140 is installed on the beam web 320 where the transfer tooling 100 needs to be installed, and the transfer tooling 100 is fixedly connected to the bottom of the semi-circular arc beam 300 through a thin steel wire rope 141. Each semi-circular arc beam 300 is installed with 2 to 4 transfer tools 100 according to the actual length. The transfer tooling 100 needs to be aligned with the partition 330 position of the semi-circular arc beam 300 (such as Figure 2a to Figure 2d shown);

[0095] After the semi-circular arc beam 300 is manufactured in the workshop, it is hoisted onto the transfer flatbed truck together with the transfer tooling 100 by the workshop crane. After being placed stably, the semi-circular arc beam 300 is transferred to the required work station by the flatbed truck 400.

[0096] After being transferred to the workstation, a tire frame 210 is arranged at the bottom of the semi-circular arc beam 300, and a pre-made shelf base 220 is arranged on the tire frame 210. The beam is stably placed on the tire frame shelf tooling 200 by a flatbed truck 400 (such as Figure 3a to Figure 3c shown);

[0097] The flatbed truck 400 is lowered until it is completely separated from the transfer tooling 100 of the semi-circular arc beam 300, and after there are no abnormal conditions, the flatbed truck 400 drives away.

[0098] The steps of using a preferred embodiment of the semicircular arc beam transfer device of the utility model are as follows:

[0099] Step 1: After the semi-circular front and rear beams are formed and before the structure leaves the workshop, a fixed lifting lug 140 for transportation is installed on the semi-circular beam 300.

[0100] Step 2: When the semi-circular front and rear beam structures are transported out of the workshop, the transfer tooling 100 is installed to the bottom of the beam and connected and fixed. The steel wire rope 141 connecting the semi-circular beam 300 and the transfer tooling 100 needs to be about 200mm larger than the actual theoretical distance between the two ear holes, so that there is a gap between the transfer tooling 100 and the semi-circular beam 300 to facilitate the subsequent sandblasting and painting of the structure.

[0101] Step 3: hoist the semi-circular arc beam 300 as a whole onto the flatbed truck 400 to ensure that the transfer tooling 100 and the partition 330 of the beam structure are aligned.

[0102] Step 4: When the semi-circular arc beam 300 is transported, the flatbed truck 400 directly lifts up the transport tooling 100 to contact and bear force with the semi-circular arc beam 300. After the semi-circular arc beam 300 is transported to the assembly site, the transport tooling 100 is not removed to facilitate the subsequent transport of components.

[0103] Step 5: After the semi-circular arc beam 300 is transported to the required site, it is stably placed on the tire frame placing tool 200.

[0104] In summary, the semi-circular arc beam transfer device of the utility model has the following advantages:

[0105] The semi-circular arc beam transfer device of the utility model is designed for the bottom arc structure of the semi-circular arc beam, which can ensure that the overall structure of the beam is stable during the transfer process and is not prone to shaking, thereby improving the stability of the transfer, which is crucial for protecting the beam from damage and improving the transfer efficiency. The transfer device is provided with an anti-overturning support to ensure that the beam is stabilized during the transfer of the beam, further improving the safety of the transfer. The fixed lifting lug is flexibly connected to the anti-overturning support, which improves the production efficiency and avoids repeated disassembly and installation of the tooling.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principle and essence of the present invention, but these changes and modifications fall within the protection scope of the present invention.
