Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an anti-skid tower crane ladder. Background Art

[0002] Tower cranes are mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. They are mainly composed of ladder columns and beams. The cockpit of the tower crane is located at the top of the tower crane, and the operator often needs a ladder to climb into the cockpit to work.

[0003] At present, the existing crane ladders are mostly used in outdoor operations during use, and in order to ensure the anti-skid effect, the existing ladders are mostly equipped with wider ladder crossbeams. Therefore, in rainy and snowy weather, rain and snow will remain on the ladder bars, causing the ladder to slip easily. In addition, the existing ladders have poor anti-skid effects, which affects the practicality of tower crane ladders. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing crane ladder in the prior art is that most of the existing crane ladders are used in the open air, and the existing ladders are mostly provided with wider ladder crossbeams to ensure the anti-skid effect. Therefore, in rainy and snowy weather, rain and snow will remain on the ladder rods, causing the ladder to slip easily. In addition, the anti-skid effect of the existing ladder is poor, which affects the practicality of the tower crane ladder. A non-skid tower crane ladder is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A non-slip tower crane ladder comprises two ladder columns, a plurality of ladder beams are fixedly connected between the two ladder columns, a V-shaped groove is provided on the top of the ladder beam, a hand grip and a vertical plate are fixedly connected to the inner wall of the bottom of the V-shaped groove of the ladder beam, an anti-slip pad is sleeved on the outer wall of the hand grip, and two water seepage holes are provided at the bottom of the V-shaped groove.

[0007] Furthermore, a plurality of reinforcing ribs are fixedly connected between the ladder columns and the ladder beams.

[0008] Furthermore, the anti-slip pad is a silicone sleeve.

[0009] Furthermore, the outer wall of the anti-slip pad is provided with a protective groove.

[0010] Furthermore, a guardrail is fixedly connected to one side between the two ladder posts.

[0011] The beneficial effects of the utility model are:

[0012] 1. By providing a V-shaped groove on the ladder beam, rain and snow fall on the V-shaped groove of the ladder beam, thereby preventing rain and snow from falling on the ladder beam, thereby preventing slipping when climbing the ladder.

[0013] 2. Through the arrangement of the ladder beam and the vertical plate, when climbing the ladder, the feet are stepped on the ladder beam and the vertical plate, and the feet are stuck between the hand grip and the ladder beam, thereby preventing the feet from falling off the ladder beam.

[0014] 3. Through the setting of the seepage holes, rainwater and snow water are discharged from the seepage holes, thereby preventing rainwater and snow water from accumulating in the V-shaped groove of the ladder beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A skid-proof tower crane ladder comprises two ladder columns 1, a plurality of ladder beams 2 are welded between the two ladder columns 1, a V-shaped groove is arranged on the top of the ladder beam 2, rain and snow fall on the V-shaped groove of the ladder beam 2, thereby preventing rain and snow from falling on the ladder beam 2, and further preventing slipping when climbing the ladder, a hand grip 4 and a vertical plate 7 are welded on the inner wall of the bottom of the V-shaped groove of the ladder beam 2, an anti-skid pad 5 is sleeved on the outer wall of the hand grip 4, two seepage holes 8 are arranged at the bottom of the V-shaped groove, rainwater and snow water are discharged from the seepage holes 8, thereby preventing rainwater and snow water from accumulating in the V-shaped groove of the ladder beam 2.

[0021] A plurality of reinforcing ribs 3 are welded between the ladder columns 1 and the ladder beams 2 to enhance the firmness of the connection between the ladder columns 1 and the ladder beams 2. The anti-slip pad 5 is a silicone sleeve, and a protective groove 6 is provided on the outer wall of the anti-slip pad 5. A guardrail 9 is welded on one side between the two ladder columns 1, and the guardrail 9 is designed to provide protection when climbing the ladder.

[0022] The working principle of this embodiment is as follows: when in use, in rainy and snowy weather, rain and snow fall on the V-shaped groove of the ladder beam 2, thereby preventing rain and snow from falling on the ladder beam 2, and further preventing slipping when climbing the ladder; then, rainwater and snow water are discharged from the seepage holes 8, thereby preventing rainwater and snow water from accumulating in the V-shaped groove of the ladder beam 2; when climbing the ladder, the feet are stepped on the ladder beam 2 and the vertical plate 7, and the feet are stuck between the hand grip 4 and the ladder beam 2, thereby preventing the feet from falling off the ladder beam 2; the guardrail 9 is used for protection when climbing the ladder.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
