DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Embodiment 1

[0031] As Figures 1-3 shown, a safety mother rope fixing device comprises a fixing assembly and a safety mother rope 2. In the embodiment, the fixing assembly is provided as a group, and the fixing assembly comprises two brackets 3 which are arranged at intervals on the same I-shaped steel beam 1. The safety mother rope 2 is arranged between the two brackets. Among them, the bracket 3 comprises an installation base 9 and a lifting rod 4 arranged on the installation base 9.

[0032] The mounting base 9 includes a base plate 10, two L-shaped clamping plates 11, an adjusting screw 12, a pressure plate 14, and at least two clamping bolts 15. The base plate 10 is horizontally positioned, and the two L-shaped clamping plates 11 are slidably mounted on the left and right sides of the bottom surface of the base plate 10, respectively, and are positioned opposite each other. Specifically, the base plate 10 has a sliding groove, and the top of the L-shaped clamping plates 11 is slidably connected to the sliding groove via a slider. The corners of the L-shaped clamping plates 11 are movably connected to the bottom surface of the I-beam 1, and the two L-shaped clamping plates 11 clamp the entire I-beam 1, effectively improving its torsional resistance.

[0033] The adjusting screw 12 is horizontally inserted through the upper part of the two L-shaped clamping plates 11 and is threaded to the two L-shaped clamping plates 11 through two sets of opposite threads. Both ends of the adjusting screw 12 are connected to the base plate 10 through bearing seats, and one end is connected to a rotating handle 13. The rotating handle 13 is used to drive the adjusting screw 12 to rotate, thereby causing the two L-shaped clamping plates 11 to move closer or further apart.

[0034] The pressure plate 14 is located between the I-beam 1 and the adjusting screw 12, and is horizontally positioned. All clamping bolts 15 are spaced apart, with their tails rotatably connected to the top surface of the pressure plate 14, their middle sections threadedly connected to the base plate 10, and their heads positioned above the base plate 10. In this embodiment, there are four clamping bolts 15, distributed at the four corners of the pressure plate 14, with the adjusting screw 12 positioned between the four clamping bolts 15. A handle can be provided on the top of each clamping bolt 15 for easy rotation. By rotating the clamping bolts 15, the pressure plate 14 can be driven to move up and down, cooperating with the two L-shaped clamps 11 to clamp and release the I-beam 1.

[0035] When the mounting base 9 of this utility model is connected to the I-beam 1, the two L-shaped clamps 11 are adjusted to move closer to each other by rotating the adjusting screw 12, which can clamp the left and right sides of the I-beam 1. Then, the pressure plate 14 is driven to move downward by rotating the pressing bolt 15, which, together with the lower part of the two L-shaped clamps 11, clamps the upper and lower sides of the I-beam 1, thereby fixing the mounting base 9.

[0036] This utility model adopts the method of simultaneously adjusting and fixing the L-shaped clamping plates 11 on the left and right sides. Compared with the prior art, which uses multiple bolts to lock the clamping plates on both sides respectively, this utility model reduces the operation process to a certain extent and has a better clamping effect.

[0037] The lifting rod 4 is vertically installed in the middle of the top surface of the base plate 10, and the upper portion of the lifting rod 4 is connected with a rope connecting structure for connecting the safety mother rope 2.

[0038] In the embodiment, the thickness of the fixed section 5 and the movable section 6 is 1 cm, the cross section of the fixed section 5 is 10 cm*10 cm, the distance between the adjacent two adjusting screw holes 7 on the fixed section 5 is 20 cm, and the movable section 6 can freely adjust the height of 1 m.

[0039] Therefore, the lifting rod 4 is arranged on the top surface of the mounting base 9, and the rope connecting structure for connecting the safety mother rope 2 is arranged on the upper portion of the lifting rod 4, so that the height of the safety mother rope 2 can be adjusted according to the actual situation.

[0040] The rope connecting structure comprises a connecting ring 16 arranged on the top of the movable section 6 and a connecting groove 17 arranged on the upper end of the movable section 6, and the connecting groove 17 surrounds the outer surface of the movable section 6.

[0041] In addition, the movable section 6 is provided with an anti-falling structure on one side of the connecting groove 17. The anti-falling structure comprises an L-shaped fixed block 18, a movable clamping block 19 and a pressing screw 20. One end of the L-shaped fixed block 18 is a horizontal end, and the other end is a vertical end. The horizontal end is fixedly connected with the movable section 6 and is slidably connected with the movable clamping block 19, and the vertical end is threadedly connected with the pressing screw 20. The pressing screw 20 is rotatably connected with the movable clamping block 19, and the pressing screw 20 drives the movable clamping block 19 to move close to or away from the connecting groove 17 by rotating.

[0042] The rope connecting structure of the utility model comprises the connecting ring 16 of conventional design, and further comprises a connecting groove, so that the safety mother rope 2 can be fixed by selecting a suitable mode according to the actual situation of the safety mother rope 2. If the end portion of the safety mother rope 2 is provided with a basket bolt or a connecting hook, the end portion can be directly hooked on the connecting ring 16, and if the end portion of the safety mother rope 2 is a connecting sleeve formed by reversing and tightly fixing a steel wire rope (such as Figure 1When (as shown), the connecting sleeve can be directly inserted into the connecting groove and clamped in place by the anti-detachment structure to prevent the connecting sleeve from coming off the lifting rod 4. When the anti-detachment structure is in operation, rotating the clamping screw 20 drives the movable clamping block 19 to clamp the connecting sleeve, fixing it in the connecting groove, which acts as a limiting mechanism. Using turnbuckles or reverse-folded steel wire ropes to connect the connecting sleeve to the bracket are common methods in construction.

[0043] Example 2

[0044] like Figure 4 As shown, based on Embodiment 1, in this embodiment, the rope connection structure further includes two fixed sleeves 21 spaced vertically at the upper end of the movable section 6. The fixed sleeves 21 are horizontally positioned and perpendicular to the adjusting screw 12. Each fixed sleeve 21 has a rope channel through which the safety main rope 2 passes, and is equipped with a locking screw 22 for securing the safety main rope 2. The locking screw 22 is vertically inserted into the rope channel and threadedly connected to the fixed sleeve 21. The number of fixed sleeves 21 can be determined according to actual conditions, but shall not be less than two.

[0045] When the end of the safety rope 2 is not connected to any other structure, it can pass directly through at least two fixing sleeves 21 and be locked by locking screws 22. Compared with the prior art, the present invention provides more ways to fix the safety rope 2, which can meet different needs and avoid the connection mismatch problem caused by the single fixing method of the safety rope 2 in the prior art.

[0046] Example 3

[0047] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 lies in the number of fixing components and the rope connection structure. In this embodiment, the safety main rope fixing device includes two sets of fixing components arranged symmetrically on the left and right. A crossbar 23 is detachably connected between two adjacent lifting rods 4, and the detachable connection can be a bolt connection. A sliding sleeve 24 is slidably connected to the crossbar 23, and the sliding sleeve 24 is provided with a hand-tightening screw 25 for fixing it to the crossbar 23. The sliding sleeve 24 is also connected to a rope connecting buckle 26, and is connected to the safety main rope 2 through the rope connecting buckle 26. The crossbar 23, the sliding sleeve 24, and the rope connecting buckle 26 constitute the rope connection structure. With this arrangement, the two sets of fixing components can share a single rope connection structure.

[0048] The cap beam platform generally has two I-beams 1, and the distance between the two I-beams 1 is about two meters. A set of fixing assemblies are installed on each I-beam 1. When construction is needed above one of the I-beams 1, the two sliding sleeves 24 are fixed at one end of the two horizontal rods 23 and above the two ends of the I-beam 1, so that the two ends of the safety mother rope 2 are fixed, facilitating the construction personnel to conduct construction above the I-beam 1. When construction is needed above the other I-beam 1, the two sliding sleeves 24 are unlocked and moved to the other end of the two horizontal rods 23 for fixing, so that the safety mother rope 2 is moved to above the other I-beam 1, facilitating the construction personnel to conduct construction above the other I-beam 1.

[0049] The above description is a detailed description of the preferred and feasible embodiments of the present application, but the embodiments are not used to limit the patent application range of the present application. Any equivalent changes or modified changes completed under the technical spirit of the present application should belong to the patent range covered by the present application.
