Embodiment
The lifting support that can slide is installed in the total design of the utility model for vertical ladder, both can the employment whole height of word trapeziodal modulation, vertically adjust height by vertical ladder again. Four kinds of embodiments are introduced below in conjunction with accompanying drawing.
The first embodiment: Fig. 1 Fig. 2 describes a kind of insulated lift ladder, its main body is made up of a secondary people word ladder 1 and a vertical ladder 5. Fig. 4 is visible for composition graphs 3, and the installation mode of vertical ladder 5 is: installing a lifting support between oblique terraced 2 upper ends of two of people's word ladder 1, lifting support is provided with slideway 9, and slideway 9 is slidably matched with two side frames of vertical ladder 5. Vertical ladder 5 can slideway 9 in up and down lifting and adjust highly. Here lifting support 3 and slideway 9 can have various structures form, only illustrate one in figure. Fig. 6 Fig. 7 is visible for composition graphs 5, lifting support 3 has two pieces to cut with scissors even and the back up pad 10 being mounted opposite with tiltedly terraced 2 upper ends, two clamping wheel shafts 11 are respectively had to be connected between two pieces of back up pads 10 up and down, a clamping wheel 10 is equipped with at the two ends often propping up clamping wheel shaft 11, the periphery of clamping wheel 10 is the concave surface of indent, and eight clamping wheels 10 form the slideway 9 that described and vertical terraced 5 side frames 13 are slidably matched. Two side frames 13 of vertical ladder 5 can slide up and down in slideway 9. In lifting support 3 or side, tiltedly the upper end of ladder 2 is provided with lifting pulley 4. On lifting pulley 4, rope one end of coiling connects the lower end of vertical ladder 5, and the other end is led by people and draws, and can control the lifting of vertical ladder.
Fig. 1 Fig. 2 Fig. 3 Fig. 4 is also shown in: the lower end of the oblique ladder 2 of two of people's word ladder 1 is provided with the lower margin 7 of strip. It is provided with bracing wire 8 between lower margin 7 and oblique ladder 2, thus strengthens the lateral stability of whole insulated lift ladder.
As seen from Figure 8, the two ends of two side frames of vertical ladder 5 are respectively equipped with jack 15 and joint 14, and joint 14 coordinates with jack 15 grafting, it is possible to two sections of vertical ladders or the vertical ladder of multistage are plugged in together.
During use, as shown in Figure 9, tiltedly terraced 2 separately form tripod two of people's word ladder 1, and fix with pull bar 6, more upwards insert in the middle of slideway 9 vertical terraced 5, pull rope namely to promote vertical terraced 5 by lifting pulley 4. When extreme higher position mentioned by a vertical ladder of joint, it is also possible to patch the vertical ladder of another joint below, until reaching required height, and a bottom vertical ladder of joint is supported on ground. In order to strengthen resistance to overturning, it is also possible to as shown in Figure 9, leading on the vertical top of terraced 5 and draw four lateral conductors 16, the other end of lateral conductor 16 is connected on ground or other fixtures. Experiment shows, the operation height of this kind of insulated lift ladder, more than 15 meters, compared with existing people's word ladder, when equal floor space, is heightened amplitude and stability and security and significantly improved, it is possible to adapt to the hot line work of multiple circuit.
The structural principle of the insulated lift ladder that the 2nd kind of embodiment: Figure 10 introduces is substantially identical with the first embodiment, and its improvement is: be provided with transverse axis 17 on lifting support 3, and transverse axis 17 is equipped with the safe suspension hook 18 that can hang vertical ladder 5. Visible in conjunction with Figure 11: described transverse axis 17 can have two, the both sides being located at slideway 9 respectively, above each hang a safe suspension hook 18, when vertical terraced 5 are raised to specified location, two safe suspension hooks 18 from both sides to, the horizontal pan being buckled in vertical ladder, the position of vertical ladder being fixed. There is this kind of safe suspension hook 18, it is possible to omit the vertical ladder of the joint of below.
Structural principle and the first embodiment of the insulated lift ladder that the third embodiment: Figure 12 introduces are substantially identical, its improvement is: the transverse axis 17 of lifting support 3 has two, it is located at the both sides of slideway 9 respectively, wherein it is hinged with insurance above a transverse axis and turns over plate 19, the width that plate 19 is turned in insurance is less than the spacing founding ladder two side frames 13, insurance is turned over, and during 19 horizontal, another transverse axis is crossed in front end.
The effect that plate 19 is turned in this kind of insurance is: when vertical terraced 5 rise and are, the front end that plate 19 is turned in insurance is found terraced horizontal pan and lifted, and does not affect the stroke of vertical ladder. When vertical terraced 5 fall, insurance turns over plate 19 by the downward rotation of gravity, and front end is inserted between two the side frames founding ladder and dropped on another kind of transverse axis 17, can stop the continuation whereabouts of vertical ladder, so that it is guaranteed that safety. Certainly, it is also possible to utilize insurance to turn over plate 19 and realize the vertical altitude location of terraced 5.
4th kind of embodiment: as shown in figure 13, this kind of insulated lift ladder combines the feature of first two embodiment, has both installed safe suspension hook 18, has installed again insurance and has turned over plate 19, it is possible to has been combined as required so that it is processing property and safety performance are optimized more.
