Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:
High-altitude working safety protection cage as shown in Figure 1, comprise cage body 100, this cage body 100 comprises a underframe 1 and is all fixed in side frames 2, side arm 3 and an after-frame 4 at underframe 1 top, side frame 2, side arm 3 and after-frame 4 enclose affixed and form open-topped protective zone 5 with underframe 1, after-frame 4 has connecting element 6, this connecting element 6 Fixing shrink ring has the U-shaped lock 7 for the outside forklift door frame of snap close and prong, the bottom of underframe 1 is fixed with two prong cover 8, two prongs inserted for outside forklift tine and overlaps the two bottom sides that 8 symmetries are divided into underframe 1.
Fork truck two prongs accurately stretch in prong cover 8, prevent cage body 100 from swinging, symmetrically arranged prong cover 8 improves the performance of anti-shake, anti-skidding, antihunting further, the U-shaped of the right and left ring set above safety precaution cage lock 7 is connected and fixed with forklift door frame and prong, possesses good impact resistance.Wherein, protective zone 5 supplies operating personnel for the protection of with carrying; side frame 2 can prevent personnel's health from leaning out protective zone 5; and provide protection to operating personnel; promote safety performance, U-shaped lock 7 can, according to the thickness of forklift door frame, prong, safety precaution cage binding post, adopt the solid round steel of suitable length to make U-shaped steel structure; U-shaped steel structure snap close is welded into, for fixing fork truck and cage body 100 with screw cap.Side arm 3, after-frame 4, underframe 1 and side frames 2 all can adopt rod member or pipe fitting welding, splicing builds, and this example preferably adopts galvanized pipe to carry out welding as element and builds.
For convenience of operating personnel's turnover, side arm 3 has import and export 31, and the side of these import and export 31 is hinged with the safety door 32 be provided with for operating personnel's turnover.Correspondence can set up safety lock, for pinning safety door 32.
Be connected with fork truck more securely for making cage body 100, connecting element 6 is for being divided into two stationary pipes 61 of after-frame 4 both sides, the equal ring set in top and bottom of each stationary pipes 61 has described U-shaped to lock 7, the U-shaped lock 7 being positioned at stationary pipes 61 upper end connects outside forklift door frame for ring set, and the U-shaped lock 7 being positioned at stationary pipes 61 lower end connects outside forklift tine end for ring set.Each U-shaped lock 7, by cage body 100 and fastening being fixed together of fork truck, preferably adopting single solid steel structure design, runs into impulsive force not easy fracture.
For strengthening underframe 1 intensity, promote load-carrying capacity, the bracket 12 that underframe 1 comprises mainboard frame 11 and stretched out by the bottom of mainboard frame 11 downwards, prong cover 8 is between bracing frame and bracket 12.Particularly, mainboard frame 11 comprises outside frame 111 and interior shelf 112, and interior shelf 112 to be fixed in outside frame 111 and outside frame 111 is separated to form multiple inner frame 113, and each inner frame 113 is fixed with waffle slab 114.Waffle slab 114 had both provided stable bearing capacity, possessed again higher visibility, and truck driver can see the state of personnel in safety precaution cage clearly, plays stronger safety protection function simultaneously, avoids personnel to drop from space.
As a preferred structure of prong cover 8, the prong cover 8 of this example is channel-section steel, and the notch of channel-section steel, and is located between side arm 3 and after-frame 4 upward, and mainboard frame 11 is covered in the notch of channel-section steel.
Injury accident is caused for avoiding being subject to shelf, the extruding of depot establishment thing or collision; fixed connecting end between side frame 2 and side arm 3 and the fixed connecting end between side frame 2 and after-frame 4 are connected to handrail 9; hold up surely for operating personnel; reduce dangerous; avoid aloft work personnel to hold safety protection cage top because of mistake to cause hand to exceed safety protection cage protection domain and to collide with shelf, building and injured; handrail can be painted conspicuous color; as red, yellow, be convenient to aloft work personnel accurate assurance.
While improving visibility further, promote safety performance further, the bottom envelope of side arm 3, after-frame 4 and side frame 2 is provided with close-network 10.
According to shift-forward type electri forklift turn radius, under normal circumstances, the passage width scope of design of warehouse Put-in Shelf is between 310cm to 340cm, the passage width scope of design of cross beam type shelf is between 300cm to 330cm, and the clearance breadth between Put-in Shelf storage space two heel post is 140cm.According to the inner normal shelf structural design criteria of above-mentioned industry, for ensureing the alerting ability of high-altitude working safety protection cage movement, the cage body 100 of this example is in rectangular-shaped, and the width of this cage body 100 is 91cm, and length is 112cm, is highly 120cm.
Method of the present invention is used to be, participate in after the personnel of aloft work obtain aloft work approval, must correctly to wear on request hard hat required at all times, safety shoes, fasten seat belts, and the snap close of safety strap is crossed over make an inventory cage top structure and the correct upper left corner latching in fork truck baffle plate respectively or the upper right corner (if two people stand in operation in safety precaution cage simultaneously, the snap close of the safety strap respectively carried should latch in the upper left corner and the upper right corner of fork truck baffle plate respectively by above-mentioned requirements), participate in after the personnel of aloft work enter safety precaution cage, the safety door 32 of protection cage should be locked and perform aloft work in warehouse with truck driver according to " warehouse high-altitude working safety operating instruction ".
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
