The rail double-door interlocking device of the building hoist comprises an interlocking upper mechanism and an interlocking lower mechanism; the interlocking upper mechanism comprises an upper support pipe; an upper pressing plate and a lock sleeve are sequentially welded on the upper plane of the upper support pipe; two guide rods are welded on the lower end of the upper support pipe; the interlocking lower mechanism comprises a lower pressing plate and a connecting base plate which are welded integrally; two guide sleeves are welded on the lower pressing plate; the two guided rods are respectively installed in the two guide sleeves in a sliding mode; and springs are sleeved on the guide rods. The rail double-door interlocking device of the building hoist provided by the invention is simple, compact and reasonable in structure, and guarantees that the double-door is clamped firmly after a hoisting cage is hoisted, a rail door can not be opened manually, and the safety greatly is improved, and the use is convenient.
Description
Technical field
The present invention relates to a kind of building hoist fence double door inter locking gear, specifically for pinning the fence double door of the vertical transport equipment building hoist to high-building construction, belonging to building operation implement technical field.
Background technology
Along with the fast development of Process of Urbanization Construction and modern industry, land resources is more and more in short supply, causes modern City Building to develop to high-altitude.Therefore increasing executive information systems stands from city.In the process that Process of Urbanization Construction develops rapidly, modern transportation device also progressively comes out, not only of a great variety, and function also from strength to strength, and building hoist is exactly a kind of building operation vertical transport equipment wherein.
Building hoist is the most safe, practical, the efficient vertical transport specialized equipment of high-building construction.According to Aesthetic and the diversified customer requirement of mankind nowadays, much new requirement be it is also proposed to building hoist.In order to meet the specific demand of client, the design of building hoist fence double door is applied.Double door has specious, make simple, the advantage such as easy to use, but the common building hoist double door of a lot of manufacturer production adopts conventional door lock or latch to realize locking a door at present, when building hoist work, at any time by anyone manual unlocking, very large potential safety hazard can be there is in fence gate.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of building hoist fence double door inter locking gear is provided, ensure that cage is after rising, double door is blocked firmly, and cannot open fence gate under the effect of manpower, structure is simple, safe and reliable, easy to use.
According to technical scheme provided by the invention, building hoist fence double door inter locking gear comprises chain upper mechanism and chain lower mechanism, it is characterized in that: chain upper mechanism comprises support tube, and on upper support tube, plane welds top board and lock tube successively, two pilot bars are welded in upper support tube lower end.Chain lower mechanism comprises integrally welded lower platen and connection substrate, and lower platen welds two orienting sleeves.Described two pilot bars are slidably mounted in two orienting sleeves respectively, and on pilot bar, cover has spring, the upper support tube of spring upper end contact, lower end in contact lower platen.
Further, two brace panels are welded between lower platen and connection substrate.
Further, lock tube upper end is provided with U-lag.
Further, connection substrate is provided with multiple bolt hole.
Further, lower platen and connection substrate orthogonal.
Further, two orienting sleeves are parallel to each other.
Further, two pilot bars are parallel to each other.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, and ensure that cage is after rising, double door is blocked firmly, cannot open fence gate, substantially increase safety under the effect of manpower, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is chain upper mechanism structure schematic diagram.
Fig. 3 is chain lower mechanism structure schematic diagram.
Fig. 4 is scheme of installation of the present invention.
The chain upper mechanism of description of reference numerals: 1-, the chain lower mechanism of 2-, 3-spring, 4-lock tube, 5-top board, the upper support tube of 6-, 7-pilot bar, 8-lower platen, 9-orienting sleeve, 10-brace panel, 11-connection substrate, 12-bolt hole, 13-cage, 14-fence.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 3, the present invention mainly comprises chain upper mechanism 1 and chain lower mechanism 2, and chain upper mechanism 1 comprises support tube 6, and on upper support tube 6, plane welds top board 5 and lock tube 4 successively, it is parallel to each other that two pilot bars, 7, two pilot bars 7 are welded in upper support tube 6 lower end.During use, cage is pressed on top board 5, poor by top board 5 balance height, increases area of thrust surface simultaneously, ensures that cage has enough area of thrust surface after declining.
Chain lower mechanism 2 comprises integrally welded lower platen 8 and connection substrate 11, lower platen 8 and connection substrate 11 orthogonal.Weld two brace panels 10 between described lower platen 8 and connection substrate 11, strengthen the Joint strenght between lower platen 8 and connection substrate 11 by brace panel 10.Lower platen 8 welds two orienting sleeves, 9, two orienting sleeves 9 parallel to each other.Lower platen 8, connection substrate 11 and brace panel 10 define stable support, and stability is strong, not fragile, long service life.
Described two pilot bars 7 are slidably mounted in two orienting sleeves 9 respectively.On described pilot bar 7, cover has spring 3, support tube 6 on spring 3 upper-end contact, lower end in contact lower platen 8.The cooperation of pilot bar 7 and orienting sleeve 9 serves directional tagging, and ensure that whole mechanism moves up and down in fixing track, such guarantee double door is blocked by lock tube 4.
Described lock tube 4 upper end is provided with U-lag, is mainly used in locking fence double door.During locking, double door is stuck in U-lag, ensures that double door can not be opened after cage rises.
Described connection substrate 11 is provided with multiple bolt hole 12, is connected on fence, easy disassembly by bolt by connection substrate 11.
Principle of work of the present invention is: as shown in Figure 4, and when cage leaves top board 5, the present invention enters mode of operation.Chain upper mechanism 1 can automatically upspring under the elastic force effect of spring 3, and the double door of fence can be pinned by lock tube 4 simultaneously, cannot manual unlocking.Only have when cage drop to bottom press down top board 5 time, chain upper mechanism 1 overcomes spring 3 elastic force and is depressed into and touches chain lower mechanism 2, and fence double door departs from lock tube 4, can be opened.Under the present invention can ensure that cage in working order, fence double door can not be opened by artificial external force, substantially increases safety, easy to use.
