Technical Field
The invention relates to a rooting and hooking component for a safe sliding rope.
Background
The safety sliding rope is often required to be used for high-altitude operation, and the safety belt hook is hung on the safety sliding rope by an operator to operate or walk, so that the safety protection effect is achieved. The safety sliding rope needs to be rooted and fixed every few meters due to the requirements of safety and installation, the rooting and fixing are usually realized by welding or directly fixing the safety sliding rope on an external structure through bolts, and a safety belt hook hung on the safety sliding rope cannot directly pass through the rooting and fixing points and must be unhooked first and then crossed the rooting and fixing points. If the safety belt walks along the safety sliding rope with the length of tens of meters or even hundreds of meters, the hook needs to be unhooked and hooked once when the safety belt walks for several meters, and the hook needs to be unhooked and hooked twice for the double-hook safety belt. The other situation is that two operators use the safety belt hook to move along the safety slide rope in opposite directions, and when the safety belt hook crosses over, the safety belt hook must be taken off and then hooked. So, on the one hand greatly reduced the efficiency that the operation personnel acted along safe swift current rope, on the other hand operation personnel can not hang safety hook because of afraid of the trouble, have serious potential safety hazard, increased the risk that the high altitude falls.

The fixing clamp of the assembly is clamped on the safe sliding rope and is connected with an external structure through a rooting plate to form a rooting fixing point of the safe sliding rope; the hook is sleeved with the safety slide rope through the C-shaped hook body, and the safety belt hook of the operating personnel is hooked into the hook at the bottom of the C-shaped hook body to form a high-altitude anti-falling safety structure.
As shown in fig. 4, when the hook 1 moves to one side of the rooting fixed point along the safety sliding rope 3, the rooting plate is embedded into the open end of the C-shaped hook body 11 and presses the blocking piece 13 to move downwards against the acting force of the torsion spring, so that the open end of the C-shaped hook body 11 forms a half-open state, and at the moment, the C-shaped hook body 11 can move to the other side of the rooting fixed point through the rooting plate 23. As shown in fig. 5, when the two hooks 1 move relatively on the safety slide rope 3, the two hooks form an angle of 180 degrees, the top parts of the C-shaped hook bodies 11 of the two hooks respectively pass through the open ends of the C-shaped hook bodies 11 of the other hook and press the blocking pieces 13 to move downwards, so that the two hooks 1 cross on the safety slide rope 3.
The blocking piece in the assembly hook is arranged at the opening end of the C-shaped hook body and used for blocking a steel wire rope from sliding out of the C-shaped hook body, the blocking piece shell is used for installing the blocking piece, so that the blocking piece can freely move up and down in the blocking piece shell, the end parts of the folded edges at two sides of the blocking piece shell are provided with steps, and the steps are clamped at two sides of the C-shaped hook body to prevent the blocking piece shell from rotating after a second positioning bolt is released; the torsion spring plays a role of bouncing the baffle plate, and is sleeved on the first positioning bolt; the first positioning bolt and the second positioning bolt have the positioning function of the separation blade and are used for assembling the separation blade, the separation blade shell, the C-shaped hook body and the torsion spring together. The movable clamping plate and the fixed clamping plate of the fixing clamp can tightly clamp the safe sliding rope together through the fixing bolt, the outer side of the fixed clamping plate is provided with a rooting plate, and the rooting plate can be connected with an external structure in a bolt or welding mode to form a rooting fixing point of the safe sliding rope.
The blocking piece in the hook has three position states under the matching of the torsional spring, the first positioning bolt and the second positioning bolt, the first position state is that the blocking piece enables the opening end of the C-shaped hook body to be in a completely closed state, and the upper edge of the blocking piece is propped against the upper wall of the opening end of the C-shaped hook body at the moment; the second position state is that the blocking piece moves downwards to enable the opening end of the C-shaped hook body to be in a half-open state, and at the moment, second positioning bolts penetrating through rectangular grooves in two sides of the blocking piece play a role in limiting and prevent the blocking piece from continuously sliding downwards; the third position state is that the blocking piece moves downwards completely to enable the opening end of the C-shaped hook body to be in a full-open state, and in the state, the second positioning bolt needs to be released firstly, so that the blocking piece can move downwards continuously until the arc-shaped groove at the lower edge of the blocking piece is pushed to the first positioning bolt. The first position state is a normal use state that the C-shaped hook body is hooked on the safety slide rope, and safety guarantee is provided for the high-altitude operation personnel; the second position state is the state when the hook passes through the fixing clamp, and the opening formed by the blocking piece is about half of the diameter of the safe slide rope in the state, so the safe slide rope cannot slide out of the opening end of the C-shaped hook body; the third position state is the state that the C-shaped hook body is hung in or taken out of the safe slide rope, namely the state when the hook is installed or disassembled. This subassembly passes through the design of separation blade, makes the couple during operation safety swift current rope can't deviate from the open end of C shape couple body, and when the couple was through mounting fixture, the rooting plate that the open end of C shape couple body can conveniently pass through mounting fixture to improve the efficiency that the operation personnel removed, the operation personnel can lead to the accessible current of length within range at safety swift current rope.
The problem that the couple on the safe swift current rope can't directly be crossed through the unable directness of fixed point of taking root and two couples on the safe swift current rope is effectively solved to this subassembly, and the couple need not to unhook, couple on the safe swift current rope can whole accessible current, improves the efficiency that the operation personnel acted along the safe swift current rope, makes things convenient for operation personnel's high altitude construction, stops the potential safety hazard.
