Description

Novel protection cat ladder

Technical Field

The utility model relates to a technical field of cat ladder, more specifically say so and relate to the technical field of cat ladder for transformer substation.

Background

In the construction process of transformer substation, often need face the high altitude operation of ascending a height, when ascending a height the operation, need use the cat ladder as the climbing instrument usually, at present, conventional cat ladder mainly has vertical ladder, double ladder, extension ladder, dual-purpose ladder, unilateral ladder, two-sided ladder, multi-functional ladder and goods shelves ladder etc. nevertheless because the height of these cat ladders is generally higher, and protective properties is relatively poor, consequently can cause the operation personnel to take place to fall down the ladder accident, has great potential safety hazard. Meanwhile, the length of the conventional ladder is mostly fixed, when the field environment changes, the ladder needs to be replaced to continue the operation, the time is wasted, and the labor cost is increased. In addition, the manufacturing cost of conventional ladder is higher, and occupation space is great, is not convenient for accomodate to it is not very convenient to use, wastes time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a have fine protecting effect for solving above-mentioned not enough, can effectively protect operation personnel's personal safety, and low in manufacturing cost, occupation space is little, is convenient for accomodate, the convenient novel protection cat ladder of altitude mixture control.

The utility model discloses a solve above-mentioned technical problem and the technical solution who adopts as follows:

the utility model provides a novel protection cat ladder, it is including frame mechanism, frame mechanism is including mated support and connecting rod, mated support comprises horizontal pole and mated vertical branch respectively, the horizontal pole is row fixed mounting between mated vertical branch, rotationally movable mounting is respectively on mated vertical branch at the both ends of connecting rod, and this connecting rod is located mated support's both sides portion respectively to be row and arrange, be provided with respectively on mated support's vertical branch with the corresponding stopper of connecting rod, stopper on mated support vertical branch is located the top and the below of connecting rod respectively.

The frame mechanism comprises locking bolts and locking nuts, the number of the frame mechanisms is 2-5, the vertical supporting rods are square tubes, inserting connectors corresponding to the vertical supporting rods are arranged at the lower end parts of the vertical supporting rods of the frame mechanisms except the frame mechanism located at the bottom, the frame mechanism located above is clamped in the upper part of the vertical supporting rod of the frame mechanism located below through the inserting connectors, corresponding first through holes and second through holes are formed in the inserting connectors and the vertical supporting rods respectively, the locking bolts penetrate through the first through holes and the second through holes, and the locking nuts are screwed on the locking bolts.

The number of the frame mechanisms is 1 group.

The vertical support rod and the connecting rod are respectively provided with a third through hole and a fourth through hole which correspond to each other, the limiting screw penetrates through the third through hole and the fourth through hole, and the limiting nut is screwed on the limiting screw and is welded and fixed with the limiting screw.

The utility model adopts the beneficial effect that above-mentioned technical solution can reach is:

1. adopt frame rack construction, not only the structure is very firm, does benefit to the climbing, and when the climbing, the climbing personnel are located and enclose the frame that closes and form by vertical branch, connecting rod and horizontal pole, consequently very safety has fine safeguard effect, all-round protection operation personnel's personal safety, open moreover and accomodate very convenient and fast, labour saving and time saving, simple structure simultaneously, low in manufacturing cost.

2. The quantity of frame mechanism is a plurality of, and the quantity of the high increase and decrease frame mechanism that can scramble as required to can adjust the height of cat ladder according to site environment, greatly improve the efficiency of work.

Detailed Description

Shown by figure 1, figure 2 and figure 3, a novel protection cat ladder, it is including frame mechanism, stop screw 10 and stop nut 11, frame mechanism is including mated support and connecting rod 1, mated support comprises horizontal pole 2 and mated vertical support rod 3 respectively, horizontal pole 2 is row fixed mounting between mated vertical support rod 3, rotationally movable mounting is on the vertical support rod 3 of mated support respectively at connecting rod 1's both ends, and this connecting rod 1 is located the both sides portion of mated support respectively to be row and arrange, connecting rod 1 and vertical support rod 3's relation of being connected as follows: as shown in fig. 6 and 7, the vertical support rod 3 and the connecting rod 1 are respectively provided with a third through hole 12 and a fourth through hole 13 which correspond to each other, the limit screw 10 penetrates through the third through hole 12 and the fourth through hole 13, the limit nut 11 is screwed on the limit screw 10 and is welded and fixed with the limit screw 10, and a welding spot of the limit screw 10 and the limit nut 11 is indicated by a reference numeral 14 in fig. 6. Limiting blocks 4 corresponding to the connecting rods 1 are respectively arranged on the vertical supporting rods 3 of the paired supports, and the limiting blocks 4 on the vertical supporting rods 3 of the paired supports are respectively positioned above and below the connecting rods 1 as shown in fig. 4. The number of frame structure can be 1 group also can be 2~5 groups, and when frame structure's quantity was 2~5 groups, this novel protection cat ladder was still including locking bolt 8 and lock nut 9, vertical branch 3 was the side pipe, was provided with respectively with the corresponding bayonet joint 5 of vertical branch 3 at the lower tip of vertical branch 3 except that being located the frame structure of below, and the frame structure that is located the top passes through bayonet joint 5 card and puts in the upper portion of the vertical branch 3 of frame structure that is located the below, is shown by figure 5, has seted up corresponding first through-hole and 6 second through-hole 7 on bayonet joint 5 and vertical branch 3 respectively, locking bolt 8 wears to put in first through-hole 6 and second through-hole 7, lock nut 9 is put on locking bolt 8 soon.

This novel protection cat ladder is when using, by putting it by building or power equipment that need carry out the climbing, and the operation personnel enter into and close the frame that forms by vertical branch 3, connecting rod 1 and horizontal pole 2, and the operation personnel trample and carry out the climbing on horizontal pole 2. When the novel protection ladder stand needs to be stored, the novel protection ladder stand can be folded into a state shown in fig. 8 as shown in fig. 8 and 9.
