Description

The utility model relates to the field of safety of work at heights in communications, energy, utilities and construction, namely, to a nozzle device for the upper part of the staircase to prevent the upper part of the staircase from shifting during operation, which can mainly be used for lifting on: wooden, metal and reinforced concrete supports of overhead communication lines and power lines; tree-shaped and irregularly shaped; buildings and structures with a flat surface.
Known nozzle for supporting the pole / mast KRAUSE, made of a rectangular metal profile, the edges of which have adjustable clamps for attaching the nozzle to the ladder. Two grips under the support are fixed on a rectangular profile, which can be adjusted horizontally depending on the diameter (size) of the support. (see the KRAUSE online store of ladders in the section "Accessories, ferrules for supports and spare parts" at http://krause-shop.ru/product/nasadka-dlja-opory-na-stolbmachtu-krause-122452). The KRAUSE pole / mast nozzle is designed to securely attach stairs with rungs to columns with a diameter of 100–250 mm, and can be used on stairs with an internal width of 300–400 mm.
The closest technical solution is the nozzle on the stairs (see patent RU 184480 U1, E06C 7/46 publ. 10/29/2018 Bull. No. 31), including a base made of a metal rectangular profile, at the edges of which there are adjustable clamps for attaching the nozzle for a ladder on a rectangular profile motionless (by welding, gluing, etc.) fixed U - shaped metal plate with bends along the edges on the inside of which there are spikes against slipping. U - shaped metal plate has a radius of more than 50 cm. And thus it can be applied to any support in size and diameter. Bends along the edges are parallel to the base and are involved when installing the nozzle to flat surfaces. Thus, the design of the nozzle allows you to put the ladder to any surface.
Wooden supports of overhead communication lines and high-voltage signal lines have a diameter at the apex (upper cut) of 12 to 25 cm. Reinforced concrete supports have a trapezoidal shape. Metal supports can be either round (of various diameters) or bent profiles. Trees can have an oval and irregular section shape.
U - shaped metal plate in the nozzle on the stairs (patent RU 184480U1) has a specific, provided by the nozzle design. U - shaped plate is in direct contact with the support or other working surface. The closer the radii of the U-shaped metal plate and the radius of the support are, the larger the adhesion area, the better the stability. Accordingly, the less the radius of the U - shaped metal plate and the radius of the support coincide, the smaller the adhesion area, and the worse the stability. Accordingly, the safety of work using this nozzle is changed.
The KRAUSE pole / mast nozzle is adjustable for the diameter of the supports. But this nozzle works properly if the support / pillar is regular round or trapezoidal. If the wooden support during operation is bent or deformed, if the reinforced concrete pillar in the upper part began to crumble, if the nozzle is attached to the sides of the trapezoid, as well as if we need to put the ladder on an oval and irregular tree or it will be more than 250 mm, then this nozzle will not be able to perform its function at all or will not perform it properly (the upper part of the ladder will be unstable). This nozzle is not intended for use on flat surfaces. And the working surfaces of the nozzle have a certain radius. Accordingly, here, the closer the radii of the working surfaces of the KRAUSE nozzle and the radius of the support, the larger the adhesion area, the smaller the radii of the working surfaces of the KRAUSE nozzle and the radius of the support, the smaller the adhesion area, and therefore the stability is worse.
The technical result of the proposed utility model is to create a universal nozzle for the upper part of the anti-slip ladder for any types and sizes of supports, poles, trees and flat surfaces, in which, by adjusting, it is possible to increase the adhesion area against slipping. This reduces the risk of slipping the nozzle with the ladder during operation and increases the safety of work.
The proposed nozzle on the stairs has in common with the closest analogue: the same mount for the stairs and the structure of the U - shaped profile.
The difference is as follows: the U-shaped profile of the proposed utility model is cut in the middle, two identical arcs form, connected through the plates with an adjustable screw, with which it is possible to adjust the angle of inclination of the arcs relative to each other; the arcs are connected to the frame through loops.
The essence of the utility model lies in the fact that the nozzle on the staircase includes a base made of a rectangular metal profile, the edges of which have adjustable clamps for attaching the nozzle to the staircase, the brackets to which are fixed on hinges of the arc with bends at the edges are fixedly fixed on the rectangular profile on the inside of the arches with bends there are spikes against slipping, when the arcs are closed, they make up a U-shaped profile that has a radius of more than 50 cm, in the lower part of the arc they are connected with adjustable screw, the plates are fixed to the arcs using loops.
The essence of the utility model is illustrated in the drawing, which shows a General view of the nozzle.
The nozzle on the ladder consists of a metal rectangular profile 1, along the edges of which there are adjustable clamps for attaching the nozzle to the ladder, consisting of an arm 2 with a slot for adjusting the clamp 3, an L-shaped screw 4 and a wing nut 5. On the rectangular profile 1, it is fixed (by welding, gluing, etc.), brackets 6 are fixed to which are attached to the hinges 7 of the arc 8 with bends 9 along the edges. On the inner part of the arcs 8 with bends 9 there are spikes 10 against slippage. When closed, arcs 8 make up a U-shaped profile that has a radius of more than 50 cm. At the bottom of the arc 8 they are connected through plates 11 with the help of an adjustable screw 12. In the plates 11, a thread is cut along which the screw 12. The plates 11 are fixed to the arcs 8 by means of loops 13. During rotation, screw 12 can open or close arcs 8. When rotating screw 12, arcs 8 change their position relative to loops 7, the angle of inclination between arcs 8 changes. Accordingly, depending on the diameter of the support, it is possible to adjust the fit of the working nozzle surfaces (arcs) from a support surface, increasing the adhesion area nozzles working surfaces with the support is reduced slippage. Bends along the edges are parallel to the base and are involved when installing the nozzle to flat surfaces. When you attach the nozzle to the flat surfaces of the arc 8 are in the closed position.
The device operates as follows. Before using the stairs, the nozzle is installed on the upper edge of the stairs. Using the L-shaped screws 4 and the wing nuts 5, the nozzle is attached to the sides of the stairs. Estimated location of the stairs. If the surface is even, then the adjustable screw 12 of the arc 8 closes and the bends 9 engage. If it is a support or pole, then the area of contact of the working surfaces of the nozzle is visually estimated, if necessary, adjust the arcs 8 using screw 12 to increase the area fit to the pillar or post. The ladder is attached in the required place, the nozzle abuts. Under the influence of the applied load, the spikes 10 on the inside of the structure engage with the surface and prevent the nozzles from sliding off with the ladder. Thus, the design of the nozzle allows you to increase the area of adhesion of the nozzle to the support and attach the ladder with this nozzle to any surface, does not allow the ladder to slide off the necessary surface, thereby ensuring safety when climbing and working on the ladder.
