Description

Technical Field

[0001] The utility model relates to the technical field of Bailey frame assembly, in particular to a Bailey frame auxiliary assembly structure. Background Art

[0002] Bailey frames are steel frames that form certain units and can be used to assemble into many components and equipment. Generally, when constructing a building, Bailey frames are used to assemble into Bailey beams, and construction is carried out on the Bailey beams.

[0003] Since the Bailey frames are mainly connected by bolts during splicing, the Bailey frames need to be hoisted during the splicing process, and then aligned with the already fixed Bailey frames and then spliced ​​and fixed by bolts. However, the Bailey frames are docked and fixed in mid-air, so it is inconvenient to align them in mid-air. Therefore, an assembly structure that is convenient for splicing Bailey frames is needed. Utility Model Content

[0004] In order to overcome the problem in the prior art that it is inconvenient to align the Bailey frame when it is suspended and connected, the embodiment of the utility model provides a Bailey frame auxiliary assembly structure. The technical solution is as follows:

[0005] Furthermore, a Bailey frame auxiliary assembly structure includes four brackets and four support plates connected to the brackets, the brackets are "L"-shaped, and slots are provided on both end surfaces of the brackets, connecting rods are fixedly connected to both sides of the support plates, the connecting rods are slidably connected to the slots, a plurality of circular holes are provided on the connecting rods, and the plurality of circular holes are connected, a limit rod is rotatably provided on the bracket, the other end of the limit rod is inserted into the circular hole, the cross-section of the limit rod is rectangular, the two side surfaces of the limit rod in the length direction are in contact with the inner wall of the circular hole, the thickness of the limit rod is less than the width of the connecting channel between two adjacent circular holes, and a driving mechanism for driving the limit rod to rotate is provided on the bracket.

[0006] Furthermore, two inner chambers are symmetrically provided on the bracket, and the driving structure includes a rotating rod and a first bevel gear which are horizontally rotatably arranged on the inner wall of the inner chamber, and the rotating rod is fixedly connected to the second bevel gear, the first bevel gear is meshed with the second bevel gear, a worm is fixedly connected to the rotating rod, a worm wheel is rotatably connected to the inner wall of the inner chamber, the worm and the worm wheel are meshed, and the worm wheel is fixedly connected to the limiting rod, and the driving mechanism also includes a knob arranged on the bracket, one end of the knob passes through the wall of the inner chamber and is fixedly connected to the first bevel gear.

[0007] Furthermore, both ends of the support plate are provided with inclined surfaces, all the support plates and the brackets are distributed in a circular array, and the inclined surfaces face inwards, and the inclined surfaces facilitate the insertion of the Bailey frames on both sides when the Bailey frames are docked.

[0008] Furthermore, two grooves are arranged on the inner side of the bracket, and rollers are rotatably arranged inside the grooves, and the rollers slightly protrude from the inner side surface of the bracket.

[0009] Furthermore, the rollers are symmetrically arranged on the inner side of the bracket.

[0010] Furthermore, a limit clamp is provided on the knob (the limit clamp belongs to the prior art and will not be described again here), and an identification arrow is provided on the upper end face of the knob. When the knob is rotated to the bottom, the length direction of the limit rod can be made parallel to the channel connecting the circular holes. Turning the knob to the bottom can make the limit rod rotate 90°, so that the length direction of the limit rod is perpendicular to the channel connecting the circular holes. At this time, the limit rod is stuck in the circular hole, so that the connecting rod cannot move.

[0011] Furthermore, ball head plungers are provided on both side walls at the corresponding positions of the slot and the limit rod, and circular grooves are provided on both outer side walls at the corresponding positions of the connecting rod and the circular hole. When the bracket slides until the ball head plunger is aligned with the limit rod, the ball head plunger pops out and is inserted into the circular groove and makes a sound, reminding the operator that the limit rod has reached the next circular hole position.

[0012] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device has a simple structure and is easy to use, effectively improving the installation efficiency of the Bailey frame when it is suspended and connected, and the device can also adjust the appropriate size according to the size of the Bailey frame, so the utilization rate is high;

[0013] By setting the brackets and support plates, the assembly structure can be put on the already installed Bailey frame, so that the Bailey frame is stuck inside the assembly structure, that is, the Bailey frame is surrounded by four brackets and four support plates, and then another Bailey frame to be spliced ​​with it is inserted into the four brackets and support plates from the other end of the assembly structure. The two Bailey frames to be spliced ​​are located in the four brackets and four support plates at the same time. The sizes of the brackets and the support plates just fit the Bailey frames, so the two Bailey frames will be exactly aligned. At this time, the two aligned Bailey frames can be fixed and connected by bolts. Since rollers are provided on the inner sides of the four brackets and the rollers are symmetrically distributed, it is convenient for the Bailey frame to move in the assembly structure by driving the rollers to rotate, and the assembly structure can also move on the Bailey frame that has been fixed.

[0014] By setting the circular holes and the limiting rods, the positions of the four brackets can be appropriately adjusted according to the size of the Bailey frame, that is, each limiting rod is rotated in the circular hole. When the limiting rod is rotated to be parallel to the direction of the bracket, the limiting rod can shuttle in multiple circular holes. Therefore, at this time, the connecting rod moves in the slot, so that the four brackets, four connecting rods and four support plates are separated from each other, thereby expanding the internal area of ​​the assembly structure, so that a larger or smaller Bailey frame can be inserted into the assembly structure. When the limiting rod needs to be rotated, the knob can be turned, and the rotation of the knob will drive the first gear to rotate, and the first gear will drive the second gear and the rotating rod to rotate. The rotation of the rotating rod drives the worm to rotate, and the worm drives the worm wheel to rotate. The rotation of the worm wheel can drive the limit rod connected to it to rotate, so that the limit rod rotates to a position where it can shuttle in multiple round holes. Conversely, when the limit rod needs to be fixed, just rotate the limit rod to other angles so that the limit rod is stuck in a round hole and cannot move to other round holes. At this time, the bracket and the support plate are in a fixed state, and the entire assembly structure is in a fixed state. Since the worm and the worm wheel have a self-locking effect, the limit rod can be rotated when and only when the knob is turned, so that the position of the bracket and the support plate can be adjusted.
