Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
Fig. 1 and a kind of telescopic lateral protective device for derrick crane shown in Fig. 2, including it is tower for installing
Main frame 1, the bolt of crane are fixedly mounted on the operating platform 2 of 1 inside of main frame and bolt is fixedly mounted in main frame 1
Longitudinal ladder stand 3 on side, is located on operating platform 2 to offer right above longitudinal ladder stand 3 and facilitates construction personnel or more
Mouth 4 is climbed, climbs and is welded with built-in fixed ring 5 on 4 medial surface of mouth, built-in 5 outer arcuate face of fixed ring, which passes through, is located at behaviour
The bottom support beam 6 and 1 medial surface of main frame for making 2 lower surface of platform are welded and fixed, and 1 upper end of main frame is located at longitudinal ladder stand
3 arranged on left and right sides offer arc telescopic mouth 7, are plugged with lateral protective frame 8 inside arc telescopic mouth 7, and 7 liang of arc telescopic mouth
End offers the flexible through-hole 9 that cross section is circular configuration, and lateral 8 periphery of protective frame is located at flexible 9 upper end opening position of through-hole
It sets and is cased with for controlling the lateral extruding spring 10 that lifting resets upwards of protective frame 8, lateral protective frame 8 is closely climbed on 4 side of mouth
Lateral accommodating groove 11 is offered, lateral accommodating groove 11 is internally provided with the overturning cover board 12 for being closed climbing mouth 4, overturns cover board
The 12 assembly blind hole inside being inserted on lateral 11 medial surface of accommodating groove by the connection shaft of two sides of the bottom and lateral protective frame 8 are lived
Dynamic connection.
Further, in order to cooperate climbing, lateral protective frame 8 includes outer side frame body 13 and framework 13 on the outside is welded and fixed
Internal support rail 14, further, in order to promote safety top, outer 13 top of side frame body has and prevents outer side frame body 13
The integral structure upper limit plate 15 being detached from inside arc telescopic mouth 7, outer 13 bottom of side frame body have curved to longitudinal ladder stand 3
Bent bottom support plate 16, further, in order to promote assembly firmness, the overall diameter size of outer side frame body 13 and flexible through-hole
9 internal orifice dimension sizes are identical, and further, in order to promote stretch stability, 14 width of support rail and 7 inside of arc telescopic mouth are wide
Degree size is identical, and further, in order to promote the stability of climbing mechanism, built-in 5 lower surface of fixed ring is located at arc telescopic mouth 7
Downwardly convex guide support plate 17 is all had with flexible 9 lower ending opening position of through-hole, one kind of the invention is used for tower lifting
The telescopic lateral protective device of machine is by being fixed with the built-in fixation that built-in liftable adjusts lateral protective frame 8 in climbing mouth 4
Ring 5, the overturning of overturning cover board 12 that can climb 4 position of mouth with linkage control by pulling downward on lateral protective frame 8 are stored, while
Longitudinal 3 side of ladder stand forms an auxiliary ladder, facilitates construction personnel upper and lower in climbing mouth 4, promotes the climbing surface on surface
Product, when greatly promoting climbing and usually safety.
Operating principle: under daily state, lateral protective frame 8 is because squeeze the effect of spring 10, and protrusion is in operating platform 2
Top, when people climb from the longitudinal ladder stand 3 of lower end, it is only necessary to pull lateral 8 bottom of protective frame downwards with hand, then
Lateral protective frame 8 will be declined by arc telescopic mouth 7, then pass through the support rail 14 of lateral protective frame 8 and bottom support
Plate 16 climb because longitudinal ladder stand 3 mostly be all mounted on 1 medial surface of main frame directly climb up can from climbing mouth 4
1 marginal position of nearly main frame climb out of, it is very close from outside, lead to danger close, and because lateral protective frame 8 is turned over toward decline
Hub cap plate 12 rotates into inside lateral accommodating groove 11 because being pressed against to turn over by 7 medial surface of arc telescopic mouth, and climbing mouth 4 is simultaneously
It can open, the position of the lateral protective frame 8 of script protrusion on operating platform 2 can also become relatively flat, and facilitate people to climb, when
After the completion of people's climbing, reset can be risen for lateral 8 elasticity of protective frame by squeezing spring 10, while overturn cover board 12 as weight
Power is acted on to be overturn to climbing mouth 4, and closure climbing 4 upper end opening of mouth promotes the safety for usually climbing 4 position of mouth.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
