Abstract

The utility model relates to a large-tonnage straight elevator with an intersecting beam. The large-tonnage straight elevator comprises a hoistway and a lift car, wherein lift car side guide rails are respectively arranged on the two sides of the hoistway; the lift car is formed by a crosshead sheave, an upper beam, side beams, a car platform, a lower beam and diagonal members; supporting platforms are respectively arranged on the two side surfaces of the well wall of each floor; intersecting working holes are formed in the side surface of the lower beam below the car platform; the intersecting beam is arranged in the intersecting working holes of the lower beam and hinged with the lower beam; a retraction device is arranged on one side or two sides in the lower beam; the retraction ends on the two sides of the retraction device are respectively connected with the intersecting beam. According to the technical scheme, the retraction device retracts, so that the four ends of the intersecting beam extend outwards to be clamped on the supporting platforms, the weight of the whole lift car is concentrated on the intersecting beam and the supporting platforms so as to protect the lifting part of the straight elevator, and the service life of the large-tonnage straight elevator is greatly prolonged.

Description

The large-tonnage craspedodrome cage lifter of cross coupling is housed

Technical field

The utility model relates to a kind of craspedodrome cage lifter, particularly relates to a kind of large-tonnage craspedodrome cage lifter that cross coupling is housed.

Background technology

In the prior art, as Fig. 1, Fig. 2 and shown in Figure 3, counterweight 1 on the craspedodrome cage lifter and the both sides of car 2 are provided with counterweight side rails 3 and cage side guide rail 4, because the load carrying ability of large-tonnage baggage elevator is bigger, sole mass is also very big, cage side guide rail 4 adopts two or more rows mostly, counterweight 1 slides between two guide pass of counterweight side rails 3, car 2 slides up and down on 4 on cage side guide rail, counterweight 1 is distributed in the rear portion of car 2, and elevator door apparatus 5 is installed in the front end of car 2, and counterweight 1 and car 2 be relative moving up and down respectively, the complementary interference under the guiding of guide rail separately, elevator door apparatus 19 is just understood opening and closing when car 2 rests in stop; Because the main force structure formula of the car 2 of elevator is the sedan-chair shelf structure, crosshead sheave 6 is connected with upper beam 7, put the beams in place and 7 to be connected with curb girder 8, curb girder 8 is connected with

underbeam

9,10 are connected with underbeam 9 at the bottom of the sedan-chair, 10 are connected at the bottom of digonal link 11 two ends and curb girder 8 and the sedan-chair, have formed stretching structure, can place personnel and goods on 10 at the bottom of the sedan-chair.

In the prior art, as shown in Figure 4 and Figure 5, leading boots 12 and safety tongs 13 is connected at the bottom of the sedan-chair on 10, safety tongs 13 is used for braking car 2, be not allow to touch cage side guide rail 4 at safety tongs 13 at ordinary times, otherwise can cause the braking misoperation, therefore lead boots 12 than safety tongs 13 from cage side guide rail 4 surfaces more close to.

As Fig. 6, Fig. 7, Fig. 8 and shown in Figure 9, when large-tonnage craspedodrome cage lifter needs direct carrier vehicle, vehicle has just entered car 2, car 2 can carry a bigger gravity near an end on doorway moment, 10 unexpected unbalance stress at the bottom of the sedan-chair, can topple over to one side unavoidably, rail brackets 14 is connected at the bottom of the sedan-chair on 10, press guide plate 16 usefulness to press guide plate bolt 18 to be connected on the rail brackets 14, the first half card of pressure guide plate 16 is embraced the base of cage side guide rail 4, cage side guide rail 4 can be fixed on the well enclosure 17, the bottom of leading boots 12 is connected at the bottom of the sedan-chair on 10 sides, leading the U-shaped opening inboard of boots 12 slides along cage side guide rail 4 surfaces, when occurring toppling over situation, lead boots 12 with 10 mobile at the bottom of the sedan-chair, touch cage side guide rail 4 surfaces soon, because cage side guide rail 4 is connected and fixed motionless with well

enclosure

17,10 topple over and be suppressed at the bottom of the sedan-chair, right that, As time goes on, lead boots 12 and cage side guide rail 4 often bears bigger impact, very easily cause boots 12 distortion, 4 distortion of cage side guide rail are loosening, the U-shaped mouth of leading boots 12 enlarges gradually, can not well guide car 2 to travel up and down, can not prevent that safety tongs 13 from not touching cage side guide rail 4 surfaces in the ordinary course of things, under this state, deformation displacement appears in cage side guide rail 4, lead the effect of guiding car 2 operations that boots 12 can not bring into normal play, under the motoring condition, braking maneuver just might be taken place by improper touching in safety tongs 13, hold cage side guide rail 4 tightly, elevator can not normally travel.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of large-tonnage craspedodrome cage lifter that cross coupling is housed, pass through the technical program, can actv. stop and lead the bigger impact that boots and guide rail bear, stop the damage of impacting the craspedodrome jacking equipment, the large tonnage transportation burden of load-bearing.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of large-tonnage craspedodrome cage lifter that cross coupling is housed, include hoistway and car, described hoistway both sides are provided with the cage side guide rail, described car is by crosshead sheave, put the beams in place, curb girder, at the bottom of the sedan-chair, underbeam and digonal link constitute, crosshead sheave is connected with upper beam, curb girder is fixed on the upper beam both sides, the lower end of curb girder links to each other with underbeam, be arranged on the top of underbeam at the bottom of the described sedan-chair, be connected to form stretching structure at the bottom of digonal link two ends and curb girder and the sedan-chair, the cage side guide rail is provided with leads boots and safety tongs, describedly lead boots and safety tongs is fixed on the sedan-chair bottom side, also include the right-angled crossing beam, be respectively arranged with brace table on the side, borehole wall both sides of each floor position, the side of the underbeam of side is provided with the forked working hole under the sedan-chair, described right-angled crossing beam is arranged in a crossed manner in the forked working hole of underbeam, and be hinged on the underbeam, one or both sides are respectively arranged with retractor device in underbeam, and the flexible end of described retractor device both sides is connected with the right-angled crossing beam respectively.

Described retractor device is made of the double end hydraulic ram.

Beneficial effect after the employing technique scheme is: a kind of large-tonnage craspedodrome cage lifter that cross coupling is housed; when the large-tonnage weight is loaded and unloaded; damage guide rail for preventing greater impact, lead boots and safety tongs; pass through the technical program; retractor device shrinks; make protruding being installed on the brace table of four ends of right-angled crossing beam; the load-bearing of whole carriage is all concentrated on right-angled crossing beam and the brace table; lifting position in the craspedodrome elevator is protected, improved the service life of large-tonnage craspedodrome cage lifter greatly.
