Description
Technical Field
The utility model relates to a rope ladder head device, especially a multi-functional rope ladder head device.
Background
At present, the rope ladder head is mainly applied to the operation of leading out a wire of a power transmission line, and two modes of leading in the wire are mainly adopted.
The first is that the operator takes the rope ladder head and moves from the insulator to the maintenance operation point to perform the operation. The operation mode has the defects that the rope ladder head anti-falling piece abrades the wire due to uneven stress in the moving process of an operator, burrs of the wire are increased, the loss of electric quantity is aggravated, and the health of equipment is influenced.
The second operation mode is as follows: ground operating personnel are connected with the rope ladder through the rope ladder head, lift the rope ladder to a wire operating point from the ground, and high-altitude operating personnel climb to the wire operating point from the ground and sit on the rope ladder head for maintenance. The existing rope ladder head is not provided with an anti-falling device, a rope can only penetrate through the rope ladder head, one end of the rope ladder head is tied to a safety belt of an overhead worker, and the other end of the rope ladder head is pulled by a ground worker. Because there is no reliable anti-falling device, there is a great potential safety hazard.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a multi-functional rope ladder head device can protect the wire and also can improve factor of safety. The technical scheme of the utility model is specifically as follows:
a multifunctional rope ladder head device comprises a support, wherein pulley blocks are arranged on two sides of the top of the support, each pulley block on each side comprises an upper pulley and a lower pulley, a wire penetrates through the space between the upper pulley and the lower pulley, a holding rod is arranged on the support below the pulley blocks, a bearing rod is arranged on the support below the holding rod, and a first cross rod and a second cross rod are sequentially arranged on the support below the bearing rod.
Furthermore, the holding rod and the bearing rod are arc-shaped, the holding rod and the support are positioned on the same plane, the bearing rod is perpendicular to the plane where the support is positioned, and the holding rod is provided with a falling prevention device.
Furthermore, the pulley block is fixed with the fixed rod through the top of the bracket, and the anti-falling piece is arranged on the bracket below the pulley block.
Furthermore, the anti-falling device is a human body speed difference type anti-falling device for high-altitude operation.
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) the utility model discloses on the basis of original a pulley, add a pulley again and form the assembly pulley for the wire passes through from between the assembly pulley, and the pulley of below has certain bearing effect to the wire, reduces the atress of a direction, and the wire parcel is between two pulleys during the operation, and the wire can not wear and tear, prolongs its life.
(2) The utility model discloses increased anti-falling device, protected high altitude construction personnel at whole rope ladder's in-process, improved factor of safety.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a side view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, the multifunctional rope ladder head device of the present embodiment includes a support 4, pulley blocks are disposed on two sides of the top of the support 4, each pulley block includes an upper pulley 2 and a lower pulley 3, a wire 10 passes through between the upper pulley 2 and the lower pulley 3, a holding rod 5 is disposed on the support below the pulley block, a support bar 6 is disposed on the support below the holding rod 5, and a first cross bar 7 and a second cross bar 8 are sequentially disposed on the support below the support bar 6.
As shown in fig. 1 and 2, the holding rod 5 and the carrying rod 6 are arc-shaped, the holding rod 5 and the bracket 4 are positioned on the same plane, the carrying rod 6 is perpendicular to the plane of the bracket 4, and the holding rod 5 is provided with a falling prevention device 11. The assembly pulley passes through 4 tops of support and is fixed with the dead lever, and the dead lever is parallel with the support top, and 1 both ends of connecting horizontal pole are located respectively to dead lever one end and support top, and upper pulley 2 and lower pulley 3 locate between 4 tops of support and dead lever through the pivot, and anticreep piece 9 is located on the assembly pulley below support. The falling-prevention device 11 of the embodiment is a human body speed difference type falling protector for high-altitude operation.
When the pulley block is used, the wire 10 is arranged between the upper pulley 2 and the lower pulley 3, so that the pulley block wraps the wire, and the wire cannot be abraded in the whole moving process. The rope ladder head is connected with the rope ladder, the rope ladder is erected, and the aerial worker can climb the rope ladder to carry out operation after taking anti-falling measures.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
