The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The utility model has adopted like design plan shown in the drawings in order to solve the existing heavier problem of hydaulic lift platform safety guard.
Referring to Fig. 1; A kind of Wood-based Panel Production shown in the figure is with the safety guard of hydaulic lift platform; Comprise hydaulic lift platform 100; Be fixed with a safety gear support 210 that roughly becomes L shaped shape at 100 1 angles of hydaulic lift platform, its excess-three angle be fixed with respectively one roughly one-tenth fall the safety rope transition supporting bracket 220 of L shaped shape.
Captive joint with hydaulic lift platform 100 in the upper end of safety rope transition supporting bracket 220, the lower end offers one and holds the safety rope that safety rope passes and pass hole 221.Safety rope passes hole 221 has a segment distance apart from the bottom surface of hydaulic lift platform 100
Micro-switch 230 in the safety guard is fixed on safety gear support 210 medium positions, and crank 240 is hinged on the safety gear support 210 through rotating shaft 250, and its shaft 250 is positioned at the below of micro-switch 230.
Crank 240 is that the boundary is divided into upper and lower pivoted arm 241,242 with the point of connection with rotating shaft 250, and following pivoted arm 242 is a straight-arm, and last pivoted arm 241 is made up of oblique arm and one section straight-arm, and the straight-arm of last pivoted arm 241 contacts with the button of micro-switch 230,230 actions of touching micro-switch.These crank 240 dependence one are arranged on the last pivoted arm 241 of crank 240 and the crank Bringing-back mechanism between the safety gear frame 210 resets.
This crank Bringing-back mechanism comprises retracing spring 260 and upper and lower spring perch 270,280; Upper and lower spring perch 270,280 is separately fixed on the lower end of straight-arm and safety gear support 210 of pivoted arm 241, and retracing spring 260 is arranged on upper and lower spring perch 270, between 280.
One safety rope stretching device is installed in the lower end of safety gear support 210 in addition; This safety rope stretching device comprises the tensioning bolt 290 that passes safety gear support 210 and is spun on a pair of fastening screw nut 291,292 on the tensioning bolt 290 that a pair of fastening screw nut 291,292 is positioned at the both sides of safety gear support 210.
Safety rope is a steel rope 300 in this safety guard; One end of steel rope 300 ties up on the tensioning bolt 290, and the other end passes and ties up on the following pivoted arm 242 of crank 240 after safety rope on the safety rope transition supporting bracket 220 on hydaulic lift platform 100 its excess-three angle passes hole 221.Steel rope 300 will be positioned at hydaulic lift platform 100 belows and around hydaulic lift platform one week of 100 lower surfaces like this.
When hydaulic lift platform 100 descends; When any point touches obstacle or human body on the steel rope 300; Its produces the other end that flexural deformation causes steel rope 300 and produces the following pivoted arm 242 of displacement through crank 240 and drive crank 240 and 250 rotate around the shaft; The last pivoted arm 241 of crank 240 triggers micro-switch 230 with backward rotation, thereby the decline of hydaulic lift platform 100 is promptly stopped and reaching the purpose of protection personal security.After obstacle on the steel rope 300 disappeared, the tension force of retracing spring 260 drove crank 240 through upper spring seat 270 and automatically resets the exceptionally straight again tensioning of steel rope 300.Simultaneously, the existence of upper spring seat 270 contact that also can cause the last pivoted arm 241 of crank 240 to impact micro-switchs 230 through the violent disturbance of avoiding happening suddenly with the collision of safety gear support 210 causes switch to damage.
More than show and described groundwork of the utility model and the advantage of principal character and the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
