Abstract
The utility model relates to a gate type elevating machine whit rope breakage protecting device. Frames on both sides of lifting basket of the elevating machine are provided with a rope breakage protecting device made up of a support base and a lever type protection bracket. The protection bracket is rotatably connected with the support base through connecting pin. When rotates toward plane of the lifting basket, tail of the protection bracket can extend into a horizontal tube rod comprising standard sections of gate frame. The utility model overcomes the problem that current rope breakage protecting device has weak security, easy bend and distortion of lifting basket and the overhead bar of the gate frame caused by stress concentration. The rope breakage protecting device adopting lever principle is characterized in simple structure, strong bearing strength, safe and reliable use. When rope breaks, the rope breakage protecting device rotates quickly under gravity and stretches the tail towards the horizontal tube on the standard section of the gate frame so as to achieve rope breakage protection.
Description
Technical field
The utility model relates to a kind of building operation vertical transport facility, particularly with the gantry hoist of rope broken protector.A divider gate and bumper/spoiler thereof are housed between the door frame of its arch type lifter, also are connected with a hanging basket that carries cargo between door frame.
Background technology
In order to forfend the contingency of the disconnected rope of arch type lifter hand basket generation in service, all on hand basket, be provided with an anti-fall disconnected fender guard on the arch type lifter usually.A kind of known anti-fall disconnected fender guard is arranged; its anti-fall disconnected lifting rope is connected in the sky beam of door frame and the middle part of hanging basket, in case lifting steel cable lift-off, the hanging basket free-falling body is descending; anti-fall disconnected lifting rope will bear the pulling force of hanging basket tenesmus, and door frame sky beam will bear downward impulsive force of hanging basket tenesmus.Because of its impulsive force and pulling force away from both sides door frame fulcrum, day beam and hanging basket very easily produce flexural deformation under the impact moment effect.Therefore its anti-fall disconnected reliability and safety all can not reach requirement, and stability is also bad.
Summary of the invention
The utility model is at the deficiencies in the prior art part, and the gantry hoist of a kind of near from fulcrum, simple in structure, safe and reliable band rope broken protector is provided.
Its solution is: a kind of gantry hoist with rope broken protector; have between the door frame one can lifting in vertical plane surface hanging basket; the hanging basket both sides are equipped with along the indigo plant of hanging of the inboard guide pillar slip of door frame and are led boots; its special character is: be positioned at and hang blue both sides and lead on the blue basket frame of hanging of boots tops the rope broken protector of being made up of bearing and lever fender bracket that is connected winch steel cable and door frame sky beam assembly pulley is housed; have the fender bracket that connects lifting steel cable rope sheave on it and be rotatably connected on the bearing by connecting pivot pin, the tail end of fender bracket can stretch on the door frame standard knot cross-arm pipe bar when blue plane rotates towards hanging.
The tail end of the fender bracket in the utility model technical solution can be shaped on the U type open slot that can snap in the inboard guide pillar of gantry hoist.
The utility model compared with prior art has following beneficial effect.
Rope broken protector is installed in the both sides of lifting hand basket, and the stress point of door frame sky beam and Lifting basket is near from fulcrum, and side supports will be hung blue gravity and be decomposed, and make it have good stable, has also avoided that elevator structure is simple and direct, bearing capacity is strong simultaneously, and is safe and reliable.In case disconnected rope takes place, lifting steel cable pulling force discharges, and fender bracket will rely on the self gravitation effect; rotate rapidly towards the Lifting basket plane; its tail end will stretch to the cross-arm pipe bar on the door frame standard knot rapidly, and Lifting basket safety is docked on the door frame, realize the breaking rope protecting to Lifting basket.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1: the front view of arch type lifter, this arch type lifter have a Lifting basket between door frame, in the both sides of Lifting basket a rope broken protector are housed respectively, and they are contained in the top that boots are led in the Lifting basket both sides separately.
Fig. 2: the monolateral matching relationship master of rope broken protector looks scheme drawing.
Fig. 3 is the birds-eye view of Fig. 2
Embodiment
Fig. 1 has described gantry hoist, and it has by holding-down bolt and the both sides door frame 12 that is fixed in the grade beam 6 on the foundation ditch of ground and is connected to form by standard knot.Door frame 12 comprises that sky beam 2, height limitator 13, weight limiting device 14, lifting rope 11, hanging basket 10, hanging basket rope sheave 9, the hanging basket on it lead boots 8, divider gate 7, coxopodite rope sheave 4, safety lever slide cartridge 3, day beam pulley set 1 assembly in known manner such as grade.The both sides of hanging basket 10 are equipped with hanging basket and are led boots 8.This hanging basket is led boots 8 and is connected in slidably on the guide pillar 15 of 12 liang of inboards of door frame, and the front and back displacement of restriction Lifting basket makes Lifting basket do oscilaltion along guide pillar 15.Rope broken protector is installed in the both sides that have the stand hanging basket, and is contained in hanging basket and leads boots tops, is fixed on the framework of hanging basket 10.
In Fig. 2, Fig. 3, the bearing 16 of rope broken protector, the seat end by bolt on the framework angle steel of hanging basket 10.The bearing end has the axis hole of a connection fender bracket 17.Fender bracket 17 can rotate in its U type groove in bearing 16 by connecting pivot pin 18.Rope sheave 19 is equipped with in fender bracket 17 terminations, and fender bracket tail end head is shaped on U type groove, and its notch can snap in guide pillar 15 cylinders of door frame 12 inboards.
In another embodiment; can be connected an extension spring between fender bracket 17 and the Lifting basket; can make lifting rope 11 tensionings like this or under disconnected rope form attitude, spur fender bracket rapidly; in the practical application; this mode and impracticable, to rely on the fender bracket deadweight to finish task of the present utility model reliable not as previous embodiment.
Above-mentionedly only listed specific embodiments more of the present utility model, to one skilled in the art, the modification of under the situation that does not exceed claim institute restricted portion, the utility model being made or revise should be at the row of protection of the present utility model.
Claims (2)
1. gantry hoist with rope broken protector; have between the door frame one can lifting in vertical plane surface hanging basket; the hanging basket both sides are equipped with along the indigo plant of hanging of the inboard guide pillar slip of door frame and are led boots; it is characterized in that: be positioned at and hang indigo plant (10) both sides and lead on the blue basket frame of hanging of boots (8) tops the rope broken protector of being made up of bearing (16) and lever fender bracket (17) is housed; described fender bracket is rotatably connected on the bearing (16) by connecting pivot pin (18), and its tail end can stretch on door frame (12) the standard knot cross-arm pipe bar when indigo plant (10) plane rotates towards hanging.
