Abstract
The utility model discloses a guardrail locking device of an equipment lifting opening safety guardrail device. The equipment lifting opening safety guardrail device comprises two guardrails which are respectively hinged at the front and the rear ends of a lifting opening, wherein the area of each guardrail is half of the area of the equipment lifting opening; the equipment lifting opening is just covered when the two guardrails are closed; the two guardrails under a closed state are locked through a guardrail locking device; the guardrail locking device comprises a jack base, a bolt base and a bolt which can slide in the bolt base; the jack base and the bolt base are opposite in position; the bolt base is integrally fixed on one of the guardrails, and the jack base is fixed on the other guardrail; the jack base is provided with a jack; an operation handle is fixed on the bolt; and the bolt can slide relative to the bolt base, so that the head of the bolt enters into or removes out of the jack.
Description
Technical field
The utility model relates to equipment hoisting mouth safety barrier device, is specifically related to the guardrail blocking device of equipment hoisting mouth safety barrier device.
Background technology
In tier building, the lifting of equipment for convenience, each floor plate has equipment to move into or take out of opening or the hole of usefulness, as the lifting mouth in the tier buildings such as the boiler of power plant, steam turbine building.In order to guarantee to lift the safety of mouth, traditional method is: under the normality, the lifting mouth covers with big block plate or flase floor, during lifting, by overhead traveling crane overburdens such as big block plate or flase floor is removed, and lifts then, after lifting is finished, overburden is resetted again.This shows that the back work operation of lifting operation is trouble very, and is extremely uneconomical, waste great amount of manpower and man-hour.
Prior art discloses a kind of at the lifting mouthful cover plate that arranges and the integrated apparatus of safety barrier, and under the normality, this device can be lived the lifting flap, and during lifting, the formation safety barrier opens it.Because equipment hoisting mouth guard rail position is following in off position, the effect that not only will bear extraneous gravity also will be born vibration force and the impact that comes from the outside simultaneously.And existing equipment lifting mouthful guardrail adopts the counterweight balance technology, and guardrail only depends on the weight effect to remain closed, and does not have the blocking function after closing, and is being subjected under the bigger vibration force effect, and guardrail may be opened automatically, has serious potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of guardrail blocking device of equipment hoisting mouth safety barrier device.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of guardrail blocking device of equipment hoisting mouth safety barrier device, equipment hoisting mouth safety barrier device comprises two guardrails that are articulated in lifting mouthful rear and front end respectively, the area of each guardrail in these two guardrails is half of equipment hoisting open area, two guardrails cut out just in time overlay device lifting mouth, two guardrails that are under the closed condition lock by the guardrail blocking device, the guardrail blocking device comprises jack base, plug housing and the latch in plug housing slidably, jack base is relative with the plug housing position, the plug housing overall fixed is on a guardrail, jack base is fixed on another guardrail, has jack on the jack base, operating grip is fixedly arranged on the latch, and the relative plug housing of latch slides so that the latch head enters or deviates from jack.
The guardrail blocking device of the said equipment lifting mouthful safety barrier device, described plug housing comprises limiting plate, guide hole plate I and guide hole plate II, along the latch length direction, limiting plate, guide hole plate I and guide hole plate II are arranged in turn, the guide hole plate II is near jack base, guide hole plate I and guide hole plate II all have the pilot hole that passes for latch, has the breach that passes for latch on the limiting plate, be provided with fairlead between guide hole plate I and the guide hole plate II, latch passes the fairlead inner chamber, slide block on the latch and fairlead internal chamber wall are slidingly connected, be with stage clip on the latch between slide block and the guide hole plate I, when fork portion was positioned at jack respectively or deviates from two stations of jack, accordingly, operating grip was resisted against respectively on two sides of limiting plate.
The utility model arranges jack base and plug housing respectively on guardrail, operating grip realizes being in the locking of two guardrails under the closed condition by the movement of latch, and it is safe and reliable to have guaranteed that guardrail cuts out, and has eliminated potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is structural representation of the present utility model, and blocking device is in the lock state.
Fig. 2 is structural representation of the present utility model, and blocking device is in released state.
Fig. 3 is the structural representation of plug housing and jack base.
Among the figure: 1 plug housing, 2 jack bases, 3 operating grips, 4 guide hole plate I, 5 fairleads, 6 guide hole plate II, 7 jacks, 8 latches, 9 slide blocks, 10 stage clips, 11 limiting plates, 12 breach, 13 pilot holes.
The specific embodiment
As Figure 1-3, a kind of guardrail blocking device of equipment hoisting mouth safety barrier device, equipment hoisting mouth safety barrier device comprises two guardrails that are articulated in lifting mouthful rear and front end respectively, the area of each guardrail in these two guardrails is half of equipment hoisting open area, and two guardrails cut out just in time overlay device lifting mouth.Be in two guardrails under the closed condition by guardrail blocking device locking, the guardrail blocking device comprises jack base 2, plug housing 1 and the latch in plug housing 8 slidably.Jack base is relative with the plug housing position, and the plug housing overall fixed is on a guardrail, and jack base is fixed on another guardrail.Have jack 7 on the jack base, operating grip 3 is fixedly arranged on the latch, the relative plug housing of latch slides so that the latch head enters or deviates from jack.
In order to realize the reliable and stable of blocking device lock-out state and released state, introduce the concrete structure of plug housing below, described plug housing comprises limiting plate 11, guide hole plate I 4 and guide hole plate II 6, along the latch length direction, limiting plate, guide hole plate I and guide hole plate II are arranged in turn, and the guide hole plate II is near jack base.Guide hole plate I and guide hole plate II all have the pilot hole 13 that passes for latch, have the breach 12 that passes for latch on the limiting plate.Be provided with fairlead 5 between guide hole plate I and the guide hole plate II, latch passes the fairlead inner chamber, slide block 9 and fairlead internal chamber wall on the latch are slidingly connected, be with stage clip 10 on the latch between slide block and the guide hole plate I, when fork portion is positioned at jack respectively or deviates from two stations of jack, accordingly, operating grip is resisted against respectively on two sides of limiting plate, as depicted in figs. 1 and 2, under the effect of stage clip, limiting plate and operating grip, no matter at lock-out state or released state, blocking device is all reliable and stable.
