Abstract
Description
Technical Field
[0001] The utility model relates to a bracket structure which is convenient for moving a shoulder strap rope and belongs to the technical field of bridge construction equipment. Background Art
[0002] During the construction of bridges, it is often necessary to work at high altitudes. For example, when constructing the cap beam and the middle tie beam, it is necessary to set up an aerial work platform on the pier, and then construct the cap beam and the middle tie beam on the aerial work platform. In order to ensure the safety of the workers during the construction process, each worker needs to wear a shoulder rope, and the other end of the shoulder rope is fixed to the transverse rod of the protective frame at the edge of the aerial work platform. Since the protective frame at the edge of the aerial work platform is formed by a number of vertical rods and transverse rods connected to each other, when the shoulder rope moves on the buckled transverse rod to the intersection of the transverse rod and the vertical rod, it is blocked by the vertical rod and cannot move further. In order to facilitate construction in other areas, the shoulder rope can only be removed and then hung on other transverse rods. Frequent replacement of the attachments of the shoulder rope not only affects the operation of the high-altitude workers, but also greatly affects the production efficiency. Utility Model Content

[0005] In the aforementioned support structure for facilitating the movement of the shoulder strap rope, the bottom edge of the vertical rod is welded and fixed to the upper anchor plate via a plurality of rib plates.
[0006] In the aforementioned support structure that facilitates the movement of the shoulder strap rope, the vertical rod includes a mother rod with a bottom, a child rod is movably inserted into the mother rod, and multiple groups of screw holes corresponding to the positions are arranged on the mother rod and the child rod. The telescopic control screw passes through the screw holes of the mother rod and the child rod to fix the two together.
[0007] In the aforementioned support structure for facilitating the movement of the shoulder strap rope, the upper anchor plate and the lower anchor plate are provided with sliding grooves corresponding to four positions, and the tension bolts are passed through the sliding grooves to lock and fix the upper anchor plate and the lower anchor plate.
[0008] In the aforementioned support structure for facilitating the movement of the shoulder strap rope, the inner wall spacing between the front and rear groups of slide grooves is greater than the width of the platform main beam.
[0009] The beneficial effects of the utility model: compared with the prior art, the utility model adopts upper and lower anchor plates, vertical rods and circular rings to form the support structure of the utility model, and a pull rope is connected between the circular rings of the two support structures. The two support structures of the same group are arranged at the left and right ends of the aerial work platform. One pull rope can cross the left and right sides of the aerial work platform. When workers work on the platform, there is no need to frequently replace the attachments of the shoulder strap rope, which significantly improves their production efficiency.

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0015] Embodiment of the utility model: a support structure for facilitating the movement of a strap rope, such as Figure 1-3 The described structure comprises an upper anchor plate 2 and a lower anchor plate 3 arranged on the top and bottom surfaces of the platform main beam 1, the upper anchor plate 2 and the lower anchor plate 3 are locked and fixed by multiple tension bolts 4, a vertical rod 5 is vertically fixed to the center of the top surface of the upper anchor plate 2, and a circular ring 6 is arranged on the top of the vertical rod 5; the described support structure is set as a group of two, and a total of two groups are arranged, and the two support structures of each group are respectively arranged on the left and right sides of the aerial work platform 7, and the two groups of support structures are respectively arranged on the front and rear sides of the aerial work platform 7.
[0016] During the installation process, the upper anchor plate 2 and the lower anchor plate 3 are first locked and fixed together with the platform main beam 1 of the aerial work platform 7 by the tension bolts 4. After the aerial work platform 7 is erected, the vertical rod 5 is welded on the upper anchor plate 2. Finally, a pull rope is connected between the circular rings 6 of the two bracket structures at the left and right ends. When the workers are working at high altitudes, they can move back and forth along the pull rope by hooking the strap rope to the pull rope, and there is no need to frequently replace the fixings of the strap rope. When the construction on the front side is completed and needs to be moved to the back side for construction, the strap rope can be hooked to the pull rope on the back side.
[0017] The bottom edge of the vertical rod 5 is welded and fixed to the upper anchor plate 2 via a plurality of rib plates 8 to improve the stability of the vertical rod 5 .
[0018] The vertical rod 5 includes a mother rod 9 at the bottom, and a sub-rod 10 is movably inserted into the mother rod 9. The mother rod 9 and the sub-rod 10 are provided with multiple groups of screw holes corresponding to the positions. The telescopic control screw 11 passes through the screw holes of the mother rod 9 and the sub-rod 10 to fix the two together. According to the progress of construction, the telescopic length of the sub-rod 10 can be reasonably adjusted by the telescopic control screw 11. Through this structure, the vertical rod 5 can be adjusted to a suitable height.
[0019] The upper anchor plate 2 and the lower anchor plate 3 are provided with four corresponding slide grooves 12. After the tension bolts 4 pass through the slide grooves 12, the upper anchor plate 2 and the lower anchor plate 3 are locked and fixed. The slide grooves 12 are provided to allow the tension bolts 4 of various sizes to pass through, which is convenient for local material installation.
[0020] The inner wall spacing between the front and rear sets of slide grooves 12 is greater than the width of the platform main beam 1. The advantage of this arrangement is that when the tension bolts 4 are extended downward, they will not contact the platform main beam 1. The tension bolts 4 are respectively arranged on both sides of the platform main beam 1 to clamp it, and there is no need to open penetration holes for the tension bolts 4 on the platform main beam 1.
