Description
Technical field
The utility model relates to a kind of safety device of construction trade, particularly a kind of falling proof device of material elevator support body mounting or dismounting.
Background technology
Material elevator is to use the most general a kind of vertical transportation machinery in the present building operation, the installation of material elevator support body (derrick) is with manually the steel member being assembled into standard knot one by one, and support body begins to raise and set up the forming apparatus support body by saving up assembly unit from underframe.Generally from assembly unit the 3rd joint standard knot, highly just reach more than three meters, assembler must be laid the operation pedal on the standard knot top, upwards set up again, up to design height, the installation of each new standard joint, all want earlier the operation pedal to be placed into earlier on the standard knot top of just having set up, the workman climbs on this highest pedal then, and the steel member above ground is transported to, is begun to set up a new joint.So, in the common operating technique, it is to be in operation on the pedal that does not have member on four sides that the dismounting personnel must have many times, along with support body raises, when assembler will have bigger danger when the eminence of support body upper end is faced idle job or industry is moved in travelling backwards on the operation pedal, though the aloft work personnel can wear safety and bring the certain safety of assurance, but when building support body, the top of support body does not generally all have suitable hook place, even there is the hook place also can limit operating personnel's mobile alerting ability greatly, the operating personnel have to often take the hook and more adjourn finish building of derrick, the so both dangerous construction speed that also influences.
In the prior art; if any the patent No. is the fall arrest protector that the Chinese utility model " material elevator fall arrest protector " of ZL00242437.1 has related to a kind of material elevator; this patent is for overcoming existing fall arrest protector Installation and Debugging trouble; do not stop the shortcoming of safety protection function and design; the CN02212442.X derrick material elevator of safety guard " band " and for example; CN02293118.X patents such as " derrick material elevator safety guards " also only relates to the fender guard that material elevator falls and hurts sb.'s feelings in operation process, do not consider in gig support body build process the effective protection to the engineering staff.
In addition; present most of installation unit is not all taked rational fall arrest safety measure when setting up the support body of material elevator (derrick); also almost become a kind of ornaments even the operating personnel is with belt; high-rise working carries out under the condition without any protection, can not guarantee not take place owing to pedal fracture, slippage, step on the high-altitude falling accident that factor such as sky causes.In order to change the mode of operation of above-mentioned this danger, effectively prevent falling of in support body is set up operating personnel, also need to design a kind of fender guard to guarantee that the engineering staff is in the support body dismounting of material elevator or the safety in the build process.
Summary of the invention
Technical problem to be solved in the utility model is the falling proof device that provides a kind of material elevator support body simple in structure, that installing/dismounting is more convenient and security protection is high to install and remove at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the falling proof device of these material elevator support body mounting or dismounting, the standard knot that the support body of this material elevator is spliced from bottom to top by more piece is set up and is formed, each described standard knot includes four column and four support bodys that are separately positioned between the adjacent described column top that vertically are provided with and supports, and, the top that is positioned at the described standard knot of going up joint most is equipped with the operation pedal, this operation running-board bracket is located at by corresponding described support body and supports on the rectangular frame that surrounds, and it is characterized in that: described falling proof device includes
Grille guard is arranged on described operation pedal below; And
Protective fence is arranged on described being positioned at around the standard knot top topmost;
Wherein, described grille guard is connected with a lanyard respectively for four jiaos, and the end of this lanyard has the safety button that can link to each other with the column of described standard knot; Described protective fence includes and removably vertically is arranged on the vertical rod that each described support body supports two ends, draws respectively between the adjacent described vertical rod to be provided with protective rope.
Consider the cage steel rope is passed through in the middle of grille guard, be convenient to the dismounting of grille guard again, described grille guard comprises two wire sides that can splice mutually, and described wire side rolls by rope at seam and buckles.
When grille guard when not supporting, unsettled hanging up is difficult to launch during construction, for grille guard can fully be launched, as preferably, described wire side is separately positioned in the U-shaped carriage, this carriage is made with light-duty hard pipe, and a rectangular frame is established and be spliced into to two described U-shaped carriage openings relatively, and described lanyard is separately fixed on the corner of described carriage.
For the ease of the dismounting of carriage, described carriage includes stock and cross bar, and two described carriages link to each other by sleeve pipe in splicing place, pass through bolted connection between the stock of each described carriage and the cross bar.
In order to realize the quick of protective fence, convenient displacement, guarantee that again protective fence has certain load intensity, it is that a cross-sectional plane is the angle steel of being inverted the L type that described support body supports, the bottom of described vertical rod have can with the suitable pinch of the cross-sectional plane that described support body supports, this pinch includes one and the top that supports of described support body offsets and a horizontal sides and a hypotenuse that is provided with along the inclined-plane that described support body supports, this pinch also has one and the base that be arranged in parallel of described horizontal sides in the bottom of described hypotenuse, and, offer a through hole on described horizontal sides and the base respectively, described support body support and described pinch between link to each other by a bolt of passing described through hole respectively.So this pinch can support close-coupled with support body dexterously, make that the stationary nodes of vertical rod and support body is comparatively firm, and mounting or dismounting are very convenient.
In order further to improve the force intensity that is subjected to of vertical rod, also be provided with cross section brace panel triangular in shape in the described vertical rod, a square edge of this brace panel and the vertical edge of described vertical rod offset, and another square edge of this reinforcement version and the horizontal sides of described pinch offset.
Compared with prior art, advantage of the present utility model is: set up at the material elevator support body and set up the fall arrest facility in the process, this falling proof device is combined into a duplicate protection system by the protective fence of grille guard in the support body and the outer Lin Bianchu of support body, the assembling of this falling proof device is simple, displacement makes things convenient for characteristics, support body set up finish after, grille guard that disassembles and protective fence can conveniently fold, carry and store, and realize repeated usage; Therefore, falling proof device of the present utility model can prevent that the workmen from vertically falling from support body, can prevent that again workmen's joint on building from outwards routing up from the edge of operation pedal during standard knot, greatly reduce aloft work personnel's falling risk, effectively ensure operating personnel's life security, have tangible economic results in society.
