Abstract
The invention discloses a speed-limiting falling prevention inspection ladder. The speed-limiting falling prevention inspection ladder comprises a first vertical ladder rod, a second vertical ladder rod and a plurality of pedal cross rods, wherein the first vertical ladder rod and the second vertical ladder rod are mutually parallel; the pedal cross rods are connected and arranged between the first vertical ladder rod and the second vertical ladder rod; a saw-toothed track chute is axially arranged on the front side of the first vertical ladder rod; a plurality of speed-limiting tensioning wheels are arranged in the saw-toothed track chute; a wire cable is connected to the axle of each speed-limiting tensioning wheel; and a buckle is connected to the tail end of each wire cable. By adopting the above structure, once a climbing person slips, the wire cables quickly slide down and pull the speed-limiting tensioning wheels, and owing to accelerated pulling of the wire cables, the speed-limiting tensioning wheels are triggered to automatically brake and get fixed in the saw-toothed track chute, so that the climbing person is prevented from continually slipping, and accordingly, the security of the climbing person is improved.
Description
Technical field
The present invention relates to bridge pier building inspection ladder field, particularly relate to a kind of inspection ladder of speed limit fall arrest.
Background technology
In order to check Railway Bridges And Piers, part Railway Bridges And Piers is installed the inspection ladder for testing staff's climbing.Check that ladder adopts angle steel welding to make usually, several grades of cross bars are set for personnel's climbing, because part Railway Bridges And Piers is higher, check that the height of ladder is corresponding also higher, bring certain danger to the climbing of testing staff.
In order to promote the safety in utilization checking ladder, part checks that the upper parcel of ladder is provided with protection bent plate, personnel are avoided to fall from the side, but check the cross bar limited width of ladder, and the environment in field is wet and slippery unavoidably, testing staff still easily slips in the process of climbing, and protect bent plate can not fall in the too many help of personnel.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of inspection ladder of speed limit fall arrest, improves the safety of climbing personnel, and the personnel that particularly climb slip when falling and protect.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the inspection ladder providing a kind of speed limit fall arrest, comprise: the first vertical terraced bar, second vertical terraced bar and several foot-operated cross bar, described first vertical terraced bar and the second vertical terraced bar parallel, described several foot-operated cross bar connects respectively and is arranged between the first vertical terraced bar and the second vertical terraced bar, the front of described first vertical terraced bar is axially provided with a saw-toothed rail chute, several speed limit regulating wheel is provided with in described saw-toothed rail chute, the wheel shaft of described speed limit regulating wheel is connected with steel cable respectively, the end of described wire rope is connected with a buckle.
In a preferred embodiment of the present invention, be parallel to each other between described several foot-operated cross bar, be welded on successively between the first vertical terraced bar and the second vertical terraced bar.
In a preferred embodiment of the present invention, the inspection ladder of described speed limit fall arrest also comprises several spaced arc protection bent plate passed through for human body.
In a preferred embodiment of the present invention, be parallel to each other between described several arc protection bent plate, the two ends of described arc protection bent plate are welded on the lateral surface of the first vertical terraced bar and the second vertical terraced bar respectively.
In a preferred embodiment of the present invention, the outside of described first vertical terraced bar and the second vertical terraced bar is respectively arranged with mounting bar, and described mounting bar is respectively arranged with installing hole.
The invention has the beneficial effects as follows: the inspection ladder of a kind of speed limit fall arrest that the present invention points out, climbing personnel are connected buckle before climbing with the buffer zone of self, then upwards climb, move up and down in saw-toothed rail chute with the traction of wire rope during speed limit regulating wheel low speed, once climbing personnel slip, wire rope glides rapidly and tears speed limit regulating wheel, speed limit regulating wheel involves and triggers self-actuating brake due to the acceleration of wire rope, be fixed in saw-toothed rail chute, avoid the continuation of personnel to glide, improve the safety of climbing personnel.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of inspection ladder one preferred embodiment of a kind of speed limit fall arrest of the present invention.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of inspection ladder of speed limit fall arrest, comprise: the first vertical terraced bar 1, second vertical terraced bar 2 and several foot-operated cross bar 3, described first vertical terraced bar 1 and the second vertical terraced bar 2 parallel, described several foot-operated cross bar 3 connects respectively and is arranged between the first vertical terraced bar 1 and the second vertical terraced bar 2, be parallel to each other between described several foot-operated cross bar 3, be welded on successively between the first vertical terraced bar 1 and the second vertical terraced bar 2.The first vertical terraced bar 2 of vertical terraced bar 1, second and several foot-operated cross bar 3 adopt angle steel to make, with low cost, easy construction, and angle steel is conducive to the surface area of foot-operated cross bar 3, are conducive to climbing.
The front of described first vertical terraced bar 1 is axially provided with a saw-toothed rail chute 11, several speed limit regulating wheel 5 is provided with in described saw-toothed rail chute 11, gear in speed limit regulating wheel 5 rotates along the tooth bar in saw-toothed rail chute 11, speed limit regulating wheel 5 self-actuating brake when acceleration or speed exceed limit value suddenly, gear stops the rotation.
The wheel shaft of described speed limit regulating wheel 5 is connected with steel cable 7 respectively, and the end of described wire rope 7 is connected with a buckle 6.Climbing personnel are connected buckle 6 before climbing with the buffer zone of self, then upwards climb.
