Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example

[0031] The utility model will be further described below in conjunction with the accompanying drawings.

[0032] like Figure 1 , 2 As shown, this embodiment provides a steel box basket arch steel arch rib segment positioning device, comprising:

[0033] A sliding seat 1, a guide trolley 2 and a mechanical arm 3, wherein the sliding seat 1 is arranged as a horizontal guide rail structure, a plurality of guide trolleys 2 are slidably arranged in the sliding seat 1, the mechanical arm 3 is connected to the top of the guide trolley 2 and can be retracted and deflected, and an electric clamp for clamping a steel arch rib segment is arranged at the top of the mechanical arm 3;

[0034] The extension plate 4 is connected to both sides of the sliding seat 1 and is installed on the ground through anchor rods.

[0035] The working principle and beneficial effects of the utility model are as follows:

[0036] The present embodiment provides a steel box basket arch steel arch rib segment positioning device, which adopts a horizontal sliding seat 1. When in use, the sliding seat 1 is moved to a ready-to-use position, and the extension plate 4 is installed on the ground through anchor rods to prevent the sliding seat 1 from tilting; a plurality of guide carts 2 are arranged in the sliding seat 1, and a mechanical arm 3 is arranged on the guiding cart 2. The electric clamps of at least two mechanical arms 4 are used to clamp a steel arch rib segment, and the two steel arch rib segments are clamped synchronously, and the guiding cart 2 is moved to drive the two steel arch rib segments to be close for positioning and splicing; the structure of the mechanical arm 3 adopts the existing technology design, such as the utility model patent with application number CN202322164510.X, which provides a design of a splicing device in an assembly and positioning device for bridge steel arch ribs.

[0037] The present embodiment provides a steel box basket arch steel arch rib segment positioning device, which adopts a combined design of a guide trolley 2 and a mechanical arm 3, thereby realizing the synchronous clamping and positioning of two groups of steel arch rib segments, and facilitating the splicing of the steel arch rib segments. By arranging an extension plate 4 structure on both sides of the sliding seat 1, the problem of the sliding seat 1 being prone to tilting due to its small width is solved, the influence of external environment such as wind load on the use of the device during assembly is reduced, the positioning accuracy of the steel arch rib segments is guaranteed, and the stability and safety of the device during use are improved.

[0038] In one embodiment, the width of the extension plate 4 is greater than that of the sliding seat 1 , and the extension is performed on the structure of the sliding seat 1 itself to prevent the sliding seat 1 from tilting due to factors such as wind force during the splicing process due to its small width.

[0039] In one embodiment, oblique support ribs are arranged between the extension plate 4 and the side wall of the sliding seat 1. The oblique support ribs are used to strengthen the extension plate 4 and the sliding seat 1, thereby improving the structural rigidity and achieving a better anti-rolling effect.

[0040] In one embodiment, the extension plate 4 can be set as an integrally formed plate structure or as a plurality of extended plates arranged at intervals. The integrally formed plate structure has better integrity, and the extended plates arranged at intervals can reduce the structural weight and production cost.

[0041] In one embodiment, a guide slot 5 is provided in the sliding seat 1, and a through slot 6 is provided at the top of the sliding seat 1, and the width of the through slot 6 is smaller than the width of the guide slot 5. The guide trolley 2 is installed in the guide slot 5 from the end of the sliding seat 1, and the top of the sliding seat 1 is closed to prevent the guide trolley 2 from escaping, thereby ensuring the accurate movement route of the guide trolley 2 and improving the positioning accuracy of the steel arch rib segment.

[0042] like Figure 3-6 As shown, in one embodiment, stop assemblies are symmetrically arranged on both sides of the top of the sliding seat 1, and the stop assemblies include:

[0043] The stop groove 7, the stop plate 8 and the rubber plate 9, the stop groove 7 is opened at the top of the sliding seat 1 and is set at the preset parking position of the guide trolley 2; the stop plate 8 is set in the stop groove 7 and slides horizontally along the stop groove 7; the rubber plate 9 is connected to the inner side of the stop plate 8;

[0044] A first guide rod 10 and a spring 11, wherein the first guide rod 10 is arranged horizontally, one end of the first guide rod 10 is connected to the stop plate 8, and the other end slides relatively with the outer side wall of the stop groove 7; the spring 11 is sleeved on the first guide rod 10, and the two ends of the spring 11 are respectively connected to the stop plate 8 and the side wall of the stop groove 7;

[0045] A second guide rod 12 and a stop guide block 13, wherein the second guide rod 12 is arranged horizontally, one end of the second guide rod 12 is connected to the stop plate 8, and the other end slides relative to the side wall of the stop groove 7; the stop guide block 13 is connected to the second guide rod 12, and a slide groove 15 with an opening facing upward is arranged at the center of the stop guide block 13;

[0046] The stop rod 14, the upper part of the stop rod 14 is set as a gripping part 141, the lower part of the stop rod 14 is set with a first connecting part 142 and a second connecting part 143, the bottom end of the gripping part 141, the top end of the first connecting part 142 and the top end of the second connecting part 143 are connected; the bottom end of the first connecting part 142 is hinged to the support of the side wall of the hinged stop groove 7, and the bottom end of the second connecting part 143 is connected to the transmission column 16, and the transmission column 16 is slidably connected in the sliding groove 15 of the stop guide block 13.

[0047] When the guide trolley 2 moves, the transmission column 16 is located at the upper part of the slide groove 15, and the rubber plate 9 is flush with the side wall of the through groove 6 or recessed in the side wall of the through groove 6.

[0048] A flexible protective cover is arranged above the retaining groove 7 .

[0049] The working principle and beneficial effects of the above technical solution are:

[0050] After the guide trolley 2 drives the mechanical arm 3 to move to the preset position, the guide trolley 2 and the mechanical arm 3 are easily displaced due to environmental factors such as wind load and the structural interaction force during the splicing process, which affects the splicing of the steel arch rib segments. Therefore, a stop assembly is provided at the preset parking position of the guide trolley 2 on the sliding seat 1. When the guide trolley 2 has not reached the preset position, the rubber plate 9 in the stop assembly is received in the stop groove 7 under the action of the spring 11, and the rubber plate 9 is flush with the side wall of the through groove 6 or recessed in the side wall of the through groove 6, so that it does not hinder the movement of the guide trolley 2. At this time, the gripping portion 141 of the stop rod 14 deflects toward the outside of the sliding seat 1 and is in an unlocked state, and the transmission column 16 is located at the upper part of the slide groove 15; when the guide trolley 2 moves to the preset position, the gripping portion 141 of the brake rod 14 is rotated inward, and the transmission column 16 is driven to slide downward in the slide groove 15 through the second connecting portion 143, thereby The stop guide block 13 is driven to move toward the guide trolley 2 until the holding portion 141 reaches a vertical state. At this time, the stop rod 14 is in a locked state, and the rubber plate 9 on the stop plate 8 moves to be close to the side of the guide trolley 2, clamping the guide trolley 2 and preventing it from moving again; when the holding portion 141 is in a vertical state, the bottom ends of the first connecting portion 142 and the second connecting portion 143 are flush, and when the guide trolley 2 shakes, the brake rod 14 is not easy to rotate and has a self-locking function; the rubber plate 9 can increase the friction of the guide trolley 2 and reduce the clamping damage to the side of the guide trolley 2.

[0051] Through the above-mentioned structural design, there is no obstruction when the guide trolley 2 moves, and it is clamped and fixed when the guide trolley 2 moves into place. The stop assembly is used to realize the stop limit of the guide trolley 2, so as to avoid the situation where the steel arch rib segment is subjected to force to cause the guide trolley 2 to shift under the influence of environmental factors such as wind load and structural interaction force during the splicing process, thereby ensuring the stability of the structure during the splicing process and improving the splicing quality of the steel arch rib segment.
