Abstract
A stay cable single cable suspension platform is characterized by comprising a walking structure and a suspension platform structure. By means of a suspension platform body which is of an aluminum alloy structure, a stay cable serves as a guide rail, a hoister serves as a driving force, and a main steel wire serves as a hoisting medium, so that the stay cable single cable suspension platform walks on two parallel stay cables in a rolling mode. Four nylon pulley blocks, the hoister, a BSO type overspeed safety lock and an upper limiter are combined to form the walking mechanism, and the four nylon pulley blocks vertically clamp the stay cable and walk on the stay cable in a rolling mode with the hoisting of the hoister; the upper limiter is installed at the highest position of the suspension platform body; and the suspension platform body is fixed on a specially-made suspension tool by a safe steel wire and connected with steel structures of the walking mechanism on two sides of the stay cable by rotation stay bolts. The stay cable single cable suspension platform is high in automation, wide in coverage area, stable in operation and low in cost, and the BSO type overspeed safety lock is used for overspeed safety protection so that double safety precautions are achieved.
Description
Technical field
The utility model relates to a kind of cape, particularly a kind of suspension cable list rope cape.
Background technology
Cable stayed bridge is a kind of new of modern bridge.In recent years; A lot of large span stayed-cable bridges have been built in the whole nation in succession, and now the suspension cable of more than half part bridge can't detect in maintenance, and it is individual that suspension cable is that steel wire mixes; The easy fracture of wire of steel wire of suspension cable even disconnected thigh under long-time load or corrosion; So the unit of detection must detect with it with special-purpose detection each skew cables at set intervals, and the suspension cable external surface is the rubber protective sleeve easy ageing of exposing to the sun and rain for a long time, and every also the needs at a distance from several years changed.
It all is to adopt the mode of engineering hanging basket mostly that existing bridge detects the maintenance means.Yet for the bridge of suspension cable formula, hanging basket can't arrive most facade at all; And the mode of this engineering hanging basket receives the limitation of wire sling, also exists maintenance apart from problem such as weak point, danger coefficient be big.
The utility model content
To existing technical problem in the above prior art of mentioning, the purpose of the utility model provides that a kind of automaticity is strong, wide coverage, security performance are high, operate steadily, the suspension cable list rope cape of the cheap and suitable market demand to be to solve the difficult problem of cable stayed bridge suspension cable maintenance.
The utility model solves the technical scheme that its technical problem adopted:
A kind of suspension cable list rope cape; It is characterized in that, form, utilize the suspension cape of an aluminium alloy structure by walking structure and suspension cape structure two parts; Do guide rail with 1 skew cables; As driving force, main rope walks on two parallel suspension cables as promoting media, rolling with elevator; Said walking structure is by 4 nylon pulley groups, elevator, and BSO type hypervelocity safety lock combines with upper limit, and said 4 nylon pulley groups are clamped single suspension cable up and down, along with the lifting rolling of elevator walks on the suspension cable; Said upper limit is installed in suspension cape highest point; Said suspension cape is fixed on the special suspender by a safe wire rope, and utilize the revolution carrying bolt be connected suspension cable both sides walking structure steel work on.
The anti-shake counterweight of a 30kg of steel work center suspention of said walking structure is to slow down cape rocking when single cable is walked.
Said suspension cape bottom also is equipped with 4 castors, makes it easy to carrying.
One end of said main rope is suspended on the special suspender through the pre-buried conduit of bridge tower, and suspender forms embedded part combination with bolted-on on the bridge tower buried plate, and the other end carries out pretension with Lever Blocks.
Also be provided with a upper limit baffle plate on the said main rope.
Said safe wire rope is through the hypervelocity of the BSO type safety on main structure safety lock; Up and down two ends the same with said main rope be separately fixed at bridge tower special fall just and the bridge floor Lever Blocks on; And wire rope is tightened through pretension; It couples together walking structure and suspension cape structure, plays the effect of security protection.
Said Lever Blocks and bridge floor built-in fitting are used bolted-on.
Said nylon pulley group can prevent to damage when guide wheel from rolling the protective material of suspension cable external surface.
Suspension cable list rope cape also is provided with a control cabinet, can control cape and steadily go up and down.
The beneficial effect of the utility model is: adopt and the utlity model has that automaticity is strong, wide coverage, operate steadily, cheap and utilize BSO type hypervelocity safety lock as the hypervelocity safeguard protection, thereby reach duplex safety measures.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1: the principle of the utility model is: utilize elevator (5) to do guide rail with suspension cable (14) and make cape upwards creep under the lifting of elevator (5) drives along suspension cable (14).Utilize BSO type hypervelocity safety lock (7) as the hypervelocity safeguard protection, thereby reach duplex safety measures.
In conjunction with Fig. 1, its structure and functional characteristics are following:
Suspension cable list rope cape is made up of walking structure and suspension cape structure two parts; Walking structure (4) is by 4 nylon pulley groups; Elevator (5); BSO type hypervelocity safety lock (7) combines with upper limit (13), and 4 nylon pulley groups are clamped single suspension cable up and down and walked on the suspension cable (14) along with the lifting rolling of elevator (5), when cape rises to electronic limit on the highest point (13) and runs into the upper limit baffle plate of pre-installing on main rope (8) (10); Cape stops to rise automatically, can only step-down operation.Because it is the protective material that damages suspension cable (14) external surface when preventing that guide wheel from rolling that suspension cable (14) external surface, uses nylon guide wheel by special material protection.
The suspension cable both sides each utilize the revolution carrying bolt to connect an aluminium alloys operating platform (16) and (3) on walking mechanism (4) steel work, and the bottom is equipped with 4 castors (17) and is convenient to the cape carrying.2 operating platforms utilize manual deceleration slew gear (15) and (6) and make 2 operating platforms remain the vertical operating personnel of the being convenient to construction of standing along with the angle difference of each skew cables.Walking mechanism (a 4) steel work center 30kg anti-shake counterweight of suspention (18) is rocked when single cable is walked to slow down cape.
Whole suspension cable list rope cape is through control cabinet (19) control; Upwards creep through elevator (5) by main rope (8); Main rope (8) is connected special suspender (12) upward as suspension centre through the steel pipe (11) that is embedded in the bridge tower with bolt; All there is such welding suspender (12) top of every skew cables, and the other end carries out pretension with Lever Blocks (1), and Lever Blocks (1) is used bolted-on with bridge floor built-in fitting (2).Also have one to be that safe wire rope (9) is through the hypervelocity of the BSO type on main structure safety lock (7); Above an end is the same with main rope (8) with a following end is separately fixed on special suspender (12) and the bridge floor Lever Blocks (1); Need carry out pretension equally, make wire rope tight.The effect of BSO type hypervelocity safety lock (7) is to be broken off or the misfunctioning of brake that promotes motor causes that the rapidly suitable suspension rod (9) of two parallel suspension rod capes is when sliding downwards by wire rope (8) when main;, speed pins safe wire rope (9) before reaching 2 times of normal speeds rapidly; Make whole cape live, be unlikely to cause the hypervelocity downhill race by safety wire rope (9) suspension.
