[0001] The utility model relates to a top end hanging and sliding device of long ladder for installing wind shield plate on wind shield wall frame belongs to ladder climbing equipment technical field. BACKGROUND
[0002] One kind is not permanent field base, and wind shield wall needs to be set up around, the wall height of this kind is generally about 20-30 meters, is composed of wall frame and wind shield plate fixed on the windward side of wall frame. There are multiple vertical columns set at equal intervals on the windward side of wall frame, and wall plate mounting columns are also arranged between adjacent vertical columns. There are also multiple horizontal railings on the windward side from top to bottom. When installing the wind shield plate, two long ladders are needed, and the installation of one wind shield plate is carried out by workers standing on the two long ladders.
[0003] The conventional long ladder is placed on the railings at the top of the wall frame. After the installation of one wind shield plate is completed, the workers need to move to the ground to move the long ladder. Since the height of the ladder is too high, it is very difficult to move the top of the ladder on the wall frame. Therefore, two people are often needed to hold up the long ladder, stabilize it and move it in the direction of movement. Sometimes, a third person is also needed to connect the top of the long ladder with a cable to pull it in the direction of movement, which is very laborious and time-consuming.
[0004] To solve the above problems, the company has invented a new long ladder, which relates to how the top of the long ladder is hung on and slides on the support guide rod arranged at the top of the wall frame. CONTENT OF THE UTILITY MODEL
[0005] The technical problem to be solved by the utility model is how to stably hang the top of the long ladder on the support guide rod and walk on it.
[0006] In view of the above problems, the technical solution provided by the utility model is as follows:
[0007] A top end hanging and sliding device of long ladder for installing wind shield plate on wind shield wall frame, comprising a hanging frame and a pulley, the hanging frame has a sliding groove with an opening downward, and the pulley is arranged at the top of the sliding groove. In working condition, the hanging frame is straddled on the support guide rod arranged at the top of the wall frame through the sliding groove, and the pulley is pressed on the support guide rod and can walk on it.
[0008] The outer periphery of the pulley has a tread groove, and the groove bottom and groove wall of the tread groove are pressed against the upper side of the support guide rod.
[0009] The pulley has two, which are respectively installed at both ends of the sliding groove.
[0010] The hanging and sliding device further comprises a locking pin, which is arranged at the lower part of the wall plate on one side of the sliding groove. After the locking pin extends into the sliding groove, it is located below the support guide rod and has a gap with the support guide rod.
[0011] The micro electric cylinder is powered by a battery.
[0012] A rectangular gap is formed in the lower part of the wall plate on the front side of the slide groove of the hanger, and a mounting seat is detachably mounted on the rectangular gap.
[0013] The micro electric cylinder is controlled by a remote controller. Advantages
[0014] 1. The top end of the long ladder can slide on the support rod, and one person can easily complete the moving operation of the long ladder.
[0015] 2. Safe and reliable, easy to operate. BRIEF DESCRIPTION OF DRAWINGS

[0021] The present utility model will be further described below in combination with the embodiments and the drawings: Embodiment One
[0022] As Figure 1 , 2As shown, a top hanging and sliding device for long ladder on windbreak wall frame to install windbreak board, including hanging frame 1 and pulley 2, the hanging frame 1 has downward opening slide groove 101, the pulley 2 is arranged at the top of the slide groove 101, in working condition, the hanging frame 1 is arranged on the support guide rod 501 at the top of the wall frame 5 through the slide groove 101, and is pressed on the support guide rod 501 by the pulley 2 and can walk on the support guide rod 501. In this way, by adding the hanging and sliding device to the long ladder 6, the worker only needs to pull the lower end of the long ladder 6 horizontally forward on the ground to separate the long ladder 6 from the ground, so that the hanging and sliding device is still pressed on the support guide rod 501 by the pulley 2, without the need to completely lift the long ladder 6, and then applying a pushing force to the lower part of the long ladder 6 in the moving direction can make the upper end of the long ladder 6 move through the pulley 2, so that the movement of the long ladder 6 on the wall frame 5 is very easy and simple.
[0023] The outer periphery of the pulley 2 has a tread groove 201, and the groove bottom and groove wall of the tread groove 201 are pressed against the upper side of the support guide rod 501. In this way, friction between the support guide rod 501 and the groove wall of the slide groove 101 during sliding is avoided.
[0024] The pulley 2 has two, which are respectively installed at both ends of the slide groove 101, so that the hanging frame 1 is balanced and pressed on the support guide rod 501, and the stability of the long ladder 6 is enhanced.
[0025] The hanging and sliding device further includes a locking pin 301, which is arranged at the lower part of the wall plate on one side of the slide groove 101, and extends into the slide groove 101 and is located below the support guide rod 501 with a gap. In this way, the hanging and sliding device can be limited on the support guide rod 501, and the pulley is prevented from derailing, and when the long ladder 6 needs to be moved, the locking pin 301 is retracted to avoid being blocked by the support block below the support guide rod 501.
[0026] A miniature electric cylinder 3 is arranged at the lower part of the wall plate on one side of the slide groove 101 of the hanging frame 1 and is powered by a battery, and the locking pin 301 is the telescopic rod of the miniature electric cylinder 3.
[0027] As shown in Figure 3 As shown in Fig. 4, a rectangular notch 102 is formed in the lower part of the wall plate on the front side of the slide groove 101 of the hanging frame 1, and a mounting seat 4 is detachably arranged on the rectangular notch 102, the mounting seat 4 is provided with a recessed position 401 opening forward, a through hole is formed in the bottom of the recessed position 401 for the locking pin 301 to pass through, and the miniature electric cylinder 3 is arranged in the recessed position 401 and its telescopic rod as the locking pin 301 passes through the through hole. In this way, during assembly, the miniature electric cylinder 3 can be fixed on the mounting seat 4 first, and then the mounting seat 4 is arranged on the rectangular notch 102 of the front wall plate, so that the assembly is more convenient.
[0028] The miniature electric cylinder 3 is controlled by a remote controller, so that the worker can control it arbitrarily after going down to the ground.
[0029] The above embodiments are only used for more clearly describing the utility model, and cannot be regarded as limiting the protection scope of the utility model, and any equivalent modification should be regarded as falling into the protection scope of the utility model.
