The specific embodiment
The utility model will be further described below in conjunction with Figure of description and embodiment:
Shown in Figure of description.A kind of safety cage, comprise main table top 2, the lifting mechanism that is installed in main table top 2 tops, Hydraulic Station 5 and an electric control system of moving up and down along a pair of vertically arranged track body frame 1, described track body frame 1 is made of montant that is vertically set on both sides and the cross bar that is installed in parallel between two montants, and the two ends of cross bar are protruded and are provided with the rectangle projection in the outside of montant and in the end; The monosymmetric card road 12 that is provided with of track body frame 1, described card road 12 is strip, and card is evenly distributed with rectangular through-hole on the road 12, and described rectangular through-hole matches with described rectangle projection; There is spring hydraulic cylinder 11 position in corresponding card road 12, the below of main table top 2 horizontal arrangement respectively, and the piston rod end of spring hydraulic cylinder 11 is provided with the wedge 13 that matches with described rectangular through-hole, and spring hydraulic cylinder 11 is connected with described electric control system; Be provided with breaking rope protecting mechanism between described lifting mechanism and the track body frame 1.
As Fig. 1, described lifting mechanism comprises lower block 4, upper pulley 3, lifting hydraulic cylinder 6, lifting pulley 9 and lifting wire rope 7; Described lower block 4 is positioned at the top of described main table top 2 and captives joint with described main table top 2, and described upper pulley 3 is positioned at the top of lower block 4; The cylinder barrel of described lifting hydraulic cylinder 6 connects the bottom of described track body frame 1, and piston rod is connected with upper pulley 3 middle parts; Described lifting pulley 9 symmetries are fixed on the both sides of upper pulley 3 upper surfaces, and lifting wire rope 7 one ends are fixed on the described track body frame 1, and the other end is walked around lifting pulley 9 and is connected on the lower block 4.
As Fig. 2; described breaking rope protecting mechanism comprises protection pulley 10 and protection steel rope 8; described protection pulley 10 symmetries are fixed on described upper pulley 3 upper surfaces and are positioned at the inboard of described lifting pulley 9; protection steel rope 8 one ends are fixed on the described track body frame 1, and the other end is walked around protection pulley 10 and is connected on the described lower block 4.
As Fig. 3, described spring hydraulic cylinder 11 comprises adapter plate 17, cylinder barrel 14 and cylinder cap, piston 15 and piston rod and retracing spring 16, described cylinder barrel 14 is positioned on the adapter plate 17, piston rod in cylinder barrel 14 an end and the end face of cylinder barrel between be provided with retracing spring 16; Adapter plate 17 is fixedly mounted on the bottom surface of described main table top 2.Retracing spring 16 not only plays the effect that resets, and also plays the effect of buffering, effectively guarantees the service life of spring hydraulic cylinder 11.
Principle of work of the present utility model is: during rising, and Hydraulic Station 5 electric motor startings, the piston rod of lifting hydraulic cylinder 6 stretches out, and the piston rod of lifting hydraulic cylinder 6 withstands upper pulley 3 and makes its rising, and upper pulley 3 drives lifting wire rope 7 and protection steel rope 8 moves up.Because be that piston rod vertically acts on movable pulley drive rope hoisting mechanism, lifting wire rope 7 and protection steel rope 8 moving velocitys are 2 times of piston traveling speed, lifting wire rope 7 and protection steel rope 8 spur lower blocks 4 and main table top 2 rises.Meanwhile, the spring hydraulic cylinder 11 of main table top 2 belows rises along card road 12 simultaneously, and stretch out with blocking under the control of electric control system, atresia is returned by 12 chance holes, road for wedge 13.
During decline, Hydraulic Station 5 electric motor startings, hydraulic oil refluxes, pressure signal is to lifting hydraulic cylinder 6, after sensing pressure signal, opens hydraulic control one-way valve in the lifting hydraulic cylinder 6, the piston rod of lifting hydraulic cylinder 6 descends by deadweight, thereby makes upper pulley 3 and lower block 4 descend, and realizes the decline of main table top 2.
Lifting wire rope 7 improves greatly compared with traditional elevating chain weight capacity and safety, if unexpected fracture appears in lifting wire rope 7 in the elevator working process, protection steel rope 8 still can hang main table top 2, prevents main table top 2 phenomenon out of control.In addition; when spring hydraulic cylinder 11 rose along card road 12, stretched out with blocking, atresia is returned by 12 chance holes, road for wedge 13, shields at any time; wedge 13 can be stuck in the rectangular through-hole in card road 12 when unexpected fracture appearred in lifting wire rope 7, avoided main table top 2 out of control.The protection mechanism duplicate protection that has wire rope breaking protection mechanism and wedge 13 and card road 12 to cooperatively interact like this, safety is high.
Except that the described technical characterictic of specification sheets, all the other technical characterictics are those skilled in the art's known technology.
The above, principles more of the present utility model just explain through diagrams, this specification sheets be not be the utility model to be confined to shown in described concrete structure and the Applicable scope, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
