The surface of the outer wall of the building is generally equipped with ladders for easy maintenance and maintenance of pipelines and lines. However, in order to prevent non-professionals or children from climbing at will, causing safety accidents, the ladders are generally more than 2.5 meters above the ground, so maintenance personnel want to To climb up the ladder, we also need to use the common ladder in our life to connect with the ladder. Through the ladder, the staff climbs to the fixed ladder outside the building for work; when climbing the ladder alone, because the ladder and the ladder are only connected. Together, after a person climbs up, due to the effect of gravity, it is easy to make the ladder slip or tilt, which poses a threat to the life safety of the staff; therefore, it is necessary to have a special person to support the ladder so that another person can safely To reach the ladder, at least two people are required to cooperate, which causes a waste of human resources.

Similarly, such problems also exist in the electric power maintenance industry. The outer wall of the substation is also fixed with a ladder that is more than 2.5 meters above the ground. When performing maintenance operations, it is also necessary to use the ladder to connect with the ladder, and the staff climbs alone. It is more dangerous, and setting up escalators for special personnel is a waste of human resources, and the labor cost increases.

Therefore, how to develop a safe and reliable ladder that can be reliably connected to the climbing ladder by one maintenance personnel is a technical problem urgently needed to be solved by those skilled in the art.

Preferably, the support beam is hinged to the upright so that the support beam can be folded and stowed.

Preferably, the supporting beam is an angle steel, one side of the angle steel has a gap, and the protruding part of the other side is hinged with the side of the vertical pole, so that the angle steel can be vertically fixed to the vertical pole around the hinge, and can be fastened to the outside of the vertical pole surface.

As a preference, the supporting beam is a channel steel, the transverse connecting plate of the channel steel is provided with a notch, and is clamped with the vertical rod, and the vertical plates on both sides of the channel steel are hinged with the vertical rod, so that the channel steel can go around the hinge and the vertical rod. The pole is fixed vertically and can be snap-fitted to the outer surface of the pole.

Preferably, multiple sets of support beams are provided along the axis of the vertical rod.

The beneficial effect of adopting the above-mentioned technical scheme is that in the prior art, the staff uses a general ladder to connect with the climbing ladder outside the building, and climbs from the ground to the working position for operation. When climbing the ladder alone, because the ladder It is only connected with the climbing ladder. After people climb up, due to the effect of gravity, it is easy to make the ladder slip or tilt, which poses a threat to the life safety of the staff; therefore, it is necessary to have a special person to support the ladder. One person can safely reach the ladder, and at least two people are required to cooperate, which causes a waste of human resources. In this scheme, a hook that can be hung on the beam of the ladder is set at the upper end of the ladder body, and a support beam is set at the bottom that can be supported on the wall to make the ladder form a certain inclination angle. It is connected, and realizes the independent ladder climbing operation of the maintenance personnel. The connection is stable and reliable, which ensures the safety of the operators, liberates the labor force, reduces the labor cost, and brings benefits to the enterprise.

Detailed ways

Below in conjunction with accompanying drawing and an embodiment the utility model is described in further detail.

As shown in Figure 1, the utility model comprises a ladder body 1, and the ladder body 1 includes a vertical bar 101 for hand-holding and a cross bar 102 for climbing, the top of the ladder body 1 is provided with a hook 2, and the bottom A support beam 3 is provided.

During use, as shown in Figure 2, the staff hangs the hook 2 on the upper end of the ladder body 1 on the wall climbing ladder 6, opens the support beam 3 at the bottom of the ladder body 1 and is vertical to the vertical bar 101 of the ladder body 1, and the support beam 3 The end of the ladder is supported on the wall 4, so that the ladder body 1 and the wall 4 form a certain inclination angle, which is convenient for the staff to climb the ladder, so that the ladder body 1 can be firmly and reliably connected with the wall climbing ladder 6, and the staff can safely climb the ladder 6 alone. Climb to the wall climbing ladder 6 from the ladder body 1 to carry out maintenance work.

Adopt above-mentioned ladder, realize the reliable connection of ladder body 1 and the wall climbing ladder 6 provided outside the building, and realize the independent ladder operation of the maintenance personnel, the connection is stable and reliable, guarantee the safety of the operators, liberate the labor force, Reduced labor costs and brought benefits to the enterprise.

Further, as shown in FIG. 1 , two hooks 2 are respectively fixed on the tops of the two uprights 101 of the ladder body 1 ; According to the structure of the ladder body 1 generally used by the staff, it includes two vertical rods 101, therefore, hooks 2 are installed on the tops of the two vertical rods, so that the force is balanced and the connection is more firm and reliable; Support beams are respectively arranged at the bottom of the rod 101, which can also maintain the balance of the force, and it is more stable for people to stand on the ladder.

Further, as shown in FIG. 1 , the support beam 3 is hinged to the vertical pole 101 so that the support beam 3 can be folded and stowed. After the staff completes the work, they need to take off the ladder and place it in the warehouse, and the latter is in other positions.
