Description
Technical field
The utility model relates to elevator technology field, is specifically related to the flexible guardrail of a kind of elevator car top.
Background technology
Sedan-chair top guard rail is mounted in a kind of protector of top, sedan-chair top, is mainly in order to prevent repair and maintenance personnelIn the time of the work of sedan-chair top, crash into because of carelessness hoistway. Most guard rail height is generally not less than 1100mm,And fixing cannot adjustment, this just requires elevator hoistways overhead larger, and most high buildingOverhead is lower, and existing guard rail can not satisfy the demands.
Utility model content
Technical problem to be solved in the utility model is to provide the flexible guardrail of a kind of elevator car top, and it can be adjustedHighly, satisfy the demands.
For achieving the above object, the technical scheme that the utility model is taked is:
The flexible guardrail of a kind of elevator car top, comprises two groups of upper and lower telescoping mechanisms of guardrail that are arranged in parallel, described in protectThe upper and lower telescoping mechanism in hurdle comprises from bottom to top spaced the first transverse slat, the second transverse slat and the 3rd horizontal stroke successivelyPlate, is fixedly connected with starting stave between the first transverse slat and the second transverse slat, and starting stave lateral surface is along firstRiser length direction offers the chute that cross section is C type, offers screw, screw on the base plate of chuteBolt is inside installed, second riser that can slide up and down along chute is installed, edge on the second riser in chuteThe second riser length direction offers elongated hole, described bolt through after elongated hole with wing nut by secondRiser is fastening, and described the 3rd transverse slat is fixed on the second riser upper end, and the second transverse slat is provided with safety switch,The 3rd transverse slat is provided with the switch coordinating with safety switch and re-packs, same one end and two of described two first transverse slatsSame one end of the second transverse slat, same one end of two the 3rd transverse slats are all connected with rear railing and make guardrail overall structureBe U-shaped.
Described the first transverse slat is L-type, and the first transverse slat is provided with for being arranged on the connecting hole on lift crosshead.
On described the second riser lateral surface, offer cross section along the second riser length direction and be U-shaped groove,Described elongated hole is opened on the base plate of groove.
Spaced apartly on the base plate of described chute be provided with two screws.
Starting stave lateral surface of the present utility model offers cross section along starting stave length direction and is C typeChute, on the second riser, offer elongated hole along the second riser length direction, the second riser passes through boltSlidably be arranged in the chute of starting stave with wing nut, thereby can adjust the height of the 3rd transverse slatDegree, reaches the object of saving hoistway overhead, and is provided with safety switch and switch re-packs, and can indirectly controlElevator processed, to ensure maintainer's safety.
Brief description of the drawings

Fig. 2 is the structural representation of retracted mode of the present utility model.
Fig. 3 is structure for amplifying schematic diagram in a-quadrant in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of elevator car top guardrail that stretches, comprises that two groups of guardrails that are arranged in parallel are upper and lowerTelescoping mechanism, the upper and lower telescoping mechanism of described guardrail comprise from bottom to top successively spaced the first transverse slat 1,Between the second transverse slat 2 and the 3rd transverse slat 3, the first transverse slats 1 and the second transverse slat 2, be fixedly connected with starting stave4, starting stave 4 lateral surfaces offer along starting stave length direction the chute 5 that cross section is C type, slidingOn the base plate of groove 5, offer screw, bolt 6 is installed in screw, in chute 5, being provided with can be along on chuteOn the second riser 7, the second risers 7 of lower slider, offer elongated hole 8 along the second riser length direction, instituteState bolt 6 through after elongated hole with wing nut 9 by fastening the second riser 7, because of the guardrail that stretches need throughThe operation of often stretching, adopts wing nut to be particularly suitable for manual operations herein, convenient and swift. The 3rd horizontal strokePlate 3 is fixed on the second riser 7 upper ends, and the second transverse slat 3 is provided with on safety switch 10, the three transverse slats 3Be provided with the switch coordinating with safety switch and re-pack 11. Same one end of two first transverse slats and two second transverse slats sameSame one end of one end, two the 3rd transverse slats is all connected with rear railing 12 and makes guardrail overall structure be U-shaped.
The first transverse slat 1 is L-type, and the first transverse slat 1 is provided with for being arranged on the connecting hole 13 on lift crosshead.
On the second riser 7 lateral surfaces, offer cross section along the second riser length direction and be U-shaped groove 14,Described elongated hole 8 is opened on the base plate of groove.
Spaced apartly on the base plate of chute 5 be provided with two screws, the second riser 7 is installed firmly.
The utility model is installed on elevator cage top bit by the connecting hole 13 on the first transverse slat 1 and boltPut, in the time that elevator normally moves, wing nut is in locking state, and guardrail is in retracted mode, switchRe-pack ramp in safety switch below; In the time that elevator need to overhaul, need maintainer to unclamp butterfly spiral shellMother, guardrail is stretched to extended state, in stretching guardrail process, switch re-pack ramp meeting and safety switchGetting an electric shock and touch in top, causes safe action, and elevator is out of service, protection maintainer safety. This practicalityNovel employing Collapsible structure, in actual installation is used, not only can ensure in the time of actual motion not shadowRing to elevator hoistways overhead, save hoistway space, and it is anti-in the time that needs overhaul, also to play safetyThe effect of protecting, meets GB requirement, moreover can move stretching out safety switch in guardrail process, controls systemThe state that all mistakes detect safety switch judges the residing state of guardrail, indirectly controls elevator, to ensureMaintainer's safety, single unit system is simple in structure, is easy to make and fitting operation, cost-saving.
