Description
Technical field
This utility model belongs to the realm of building construction, relates to one and utilizes rolling above cave mouth safety protection equipment preventing and treating footrill
Stone drops and the upset of footrill slag-tapping device is dropped and workmen is with the device of slag-tapping device high falling.
Background technology
In the power station early stage prospective design stage, often relate to utilize prospecting adit to carry out the technological means reconnoitred, and water
The many construction in power station are at high-mountain gorge areas, and prospecting adit is arranged in the high steep position of Dam Site two sides bank slope more, and trailing edge is many
For basement rock cliff, leading edge faces sky, high steep more, and workmen needs often to come and go out at operation cave mouth during footrill excavation construction
, there is following potential safety hazard: 1. footrill top Rolling Stone fall injury cave mouth is constructed and contact personnel in slags etc.；2. vehicle of slagging tap is crossed
Blindage is inverted into river and then drive workmen goes out footrill together and rolls into river, forms the security incident of high falling.These
Security incident has been common security incident in water power prospecting adit is constructed, has a strong impact on safety in production.
For safety, in footrill excavation construction, construction party can do in advance some preventative safeguard procedures to block on
Portion's Rolling Stone and the generation of reduction falling from high altitude accident.The generally practice is: be 1. provided above protection network at footrill, intercepts top rolling
Stone, prevent Rolling Stone drop injury below construction and holdee；2. place cover plate at cave mouth to block, stop top Rolling Stone；3. adopt
Interim Simple protecting railing is set up, for some key project, it is considered to more safety and work with working steel pipe scaffold etc.
Journey image, take special facture some more fastness provisional safety guide rail to strengthen cave mouth security protection work.
But there is following potential safety hazard in above-mentioned security protection: 1. protection network is generally positioned at cliff position above footrill, during early stage prospecting
Construction investment is typically small, will not build special maintenance road or climbing device, current check and reparation difficulty relatively greatly, protection
Net once breaks an ancient egg-shaped, holed wind instrument, and maintenance and inspection personnel fail to find in time, or there is fluke mind after discovery, and maintenance and inspection not in time, will
There is the accident potential that Rolling Stone is hurted sb.'s feelings；2. placing cover plate at cave mouth to block, cover plate is not the most fixed, and protection tightness is inadequate,
The most slightly carelessness is it is possible to occur cover plate to come off, the accident that Rolling Stone is hurted sb.'s feelings；3. steel pipe scaffold etc. is used to set up interim simple
Guard rail, exists that to set up mounting process complex, and it is relatively big to install fixing difficulty, and is easily artificially moved and cause safety the most hidden
Suffer from.
Therefore, in water power prospecting adit is constructed, find one can solve top Rolling Stone simultaneously and hurt sb.'s feelings and prevent construction
The cave mouth security protection way of personnel's high falling is extremely important.During the early stage prospecting footrill construction of existing power station, there is footrill
Top Rolling Stone drops and the upset of footrill slag-tapping device is dropped and workmen is with the potential safety hazard of slag-tapping device high falling, and shows
The safety such as and general prevention and treatment the strongest, relatively costly with the presence of safety prevention measure inspection reparation difficulty, securely property is not enough
Hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of water power to visit cave cave mouth safety device, with solve existing such
The technical problems such as difficulty is repaired in the inspection that device exists, securely property is the strongest, relatively costly and general prevention and treatment is not enough.
This utility model is achieved in that
A kind of water power visits cave cave mouth safety device, and it is to arrange shielded frame beam column on the cave mouth top of footrill, and
Shielded frame beam column arranges end face protective cover plate, end face protective cover plate together with being provided with between massif preventing rubber every
Pad；In footrill, both sides arrange vertical supporting beam column and side shield dividing plate, at the vertical supporting of these preventer leading edge both sides
It is provided with at least twice between beam column laterally to block beam column.
Further, during shielded frame beam column anchors into trailing edge massif.
Further, during vertical supporting beam column anchors into bottom massif.
Further, end face protective cover plate both sides, direction on the cave mouth of footrill are that inclined-plane is arranged.
Further, shielded frame beam column draws in vertical supporting beam column, stablizes vertical supporting beam column, vertical supporting beam column
Upper protective framework beam column is supported.
This utility model is by arranging upper protective framework beam column and protective cover plate, and leading edge arranges support and erosion control beam column,
Both sides arrange the preventers such as side shield dividing plate, the comprehensive prospecting adit cave mouth safety device that is provided with, effectively
Prevent and treat Rolling Stone above footrill to drop and the upset of footrill slag-tapping device is dropped and workmen is with the peace of slag-tapping device high falling
Full hidden danger, it is ensured that construction human life and the safety of property.
The utility model has the advantage of:
1. upper protective framework beam column anchors into trailing edge massif, and leading edge supports beam column and anchors into bottom massif, make whole device with
Massif combines together, enhances fastness；
2. arranging preventing rubber dottle pin, close because massif is irregular and the hollow joint of device contact site, preventing and treating Rolling Stone passes through
Hollow joint injures lower section personnel；
3. top cover plate is arranged with inclined-plane, is guided beyond cave mouth scope by domatic Rolling Stone, it is to avoid constructor below injury
Member, alleviates the destruction to preventer simultaneously；
4. upper frame beam column securing cover plate preventing and treating top Rolling Stone, draws in leading edge being supported beam column simultaneously, stablizes support beam
Bar, support beam pole pair upper frame beam column is supported, and fixing beam column of blocking, prevents workmen and equipment from going out footrill simultaneously
Roll into river.Whole device divides multiple position to be provided separately, but is integrated mutually, and easy installation and removal is flexible, can repeatedly weigh
Multiple use, reduces engineering input cost；
5. device is integrally located at cave mouth platform, and the broken an ancient egg-shaped, holed wind instrument of equipment is easily found, and easy to maintenance, integrated control is strong.
