[0027] The utility model will be further described below in combination with the embodiments and drawings: Embodiment one
[0028] As Figure 1 A long ladder for installing a windbreak board on a field windbreak wall frame, as shown in Fig. 3, comprises a ladder body 1, further comprises a sliding hanging device 2 fixed on the top of the ladder body 1, the sliding hanging device 2 comprises a hanging rack 21 and a pulley 22, the hanging rack 21 has a downwardly open sliding groove 211, the pulley 22 is arranged on the top of the sliding groove 211, a supporting guide rod 7 is arranged on the top of the wall frame 6, the hanging rack 21 in working condition straddles on the supporting guide rod 7 through the sliding groove 211, and the pulley 22 is pressed on the supporting guide rod 7 and can walk on the supporting guide rod 7. During construction, the lower end of the ladder body 1 is supported on the ground, and the upper end is limited on the supporting guide rod 7 by the sliding hanging device 2. When the long ladder needs to be moved, the worker only needs to go down to the ground, pull the lower end of the ladder body 1 horizontally forward (slightly upward) away from the ground, so that the sliding hanging device 2 is still clamped on the supporting guide rod 7 through the pulley 22, without the need to completely lift the long ladder, and then a pushing force is applied to the lower part of the long ladder in the moving direction, so that the upper end of the long ladder can be moved through the pulley 22. Through such a setting, the movement of the long ladder on the wall frame 6 is very easy and simple, and generally, one worker can complete the movement operation of the long ladder.
[0029] The supporting guide rod 7 is added to the traditional wall frame 6 to adapt to the device of the utility model, which is a cylindrical shape, the upper side and the front and back sides are smooth without any setting, and the bottom side is welded and fixed on the column 61 of the wall frame 6 through a supporting block 8, the front and back dimensions of the supporting block 8 are smaller than the diameter of the supporting guide rod 7, so as to avoid interference with the groove wall of the sliding groove 211 and affect the smooth sliding of the sliding hanging device.
[0030] The ladder body 35 is a traditional stair, and aluminum alloy material is preferably used to reduce the weight.
[0031] The ladder body 1 is fixed at an angle with the hanging rack 21, and when applied, the inclination of the ladder body 1 meets the standing requirements of personnel, and the axis of the pulley 22 is always in a horizontal state, that is, the pulley 22 is pressed on the upper side surface of the supporting guide rod 7.
[0032] The outer periphery of the pulley 22 has a tread groove 221, and the groove bottom and groove wall of the tread groove 221 are pressed on the upper side surface of the supporting guide rod 7. In this way, friction between the supporting guide rod 7 and the groove wall of the sliding groove 211 during sliding is avoided.
[0033] The pulley 22 has two, which are respectively installed at both ends of the sliding groove 211, so that the hanging rack 21 is balanced and pressed on the supporting guide rod 7, and the stability of the long ladder is enhanced.
[0034] The slide-hanging device 2 further comprises a lock pin 31 arranged at the lower part of the wall plate on one side of the slide groove 211, which extends into the slide groove 211 and is located below the support guide rod 7 with a gap. In this way, the slide-hanging device 2 can be limited on the support guide rod 7 to avoid the pulley from derailing. When the extension ladder needs to be moved, the lock pin 31 is retracted to avoid being blocked by the support block 8 below the support guide rod 7.
[0035] A micro cylinder 3 powered by a battery is arranged at the lower part of the wall plate on one side of the slide groove 211, and the lock pin 31 is the telescopic rod of the micro cylinder 3. Here, the battery is preferably a commercially available dry battery. The micro cylinder 3 is controlled by a remote controller, so that the worker can unlock through remote control after getting off the ground. Embodiment Two
[0036] As shown in Fig. Figure 4 6, which is different from the first embodiment in that the extension ladder further comprises a side support frame 4 arranged at the lower area of the middle part of the rear side of the ladder body 1, the front end of the side support frame 4 is fixed to the ladder body 1, and the rear end is clamped on one of the horizontal rods 62 on the windward side of the wall frame 6. In this way, the support strength of the middle part of the ladder body 1 can be enhanced, and the lower end of the extension ladder can be applied without touching the ground, which can avoid the difficulty of erecting the ladder caused by uneven ground.
[0037] An arc-shaped clamping groove 41 opening backward is arranged at the rear end of the side support frame 4 to enhance the adaptability and reliability of the clamping of the rear end of the side support frame 4 on the horizontal rod 62. Embodiment Three
[0038] As shown in Fig. Figure 7 , a fixed pulley 5 for lifting the wind shield by a cable is arranged at the upper part of the ladder body 1.
[0039] The above embodiments are only used to more clearly describe the utility model, and cannot be regarded as limiting the protection scope covered by the utility model. Any equivalent modification shall be regarded as falling within the protection scope covered by the utility model.
