Abstract
A pedal turning type portable ladder is a special ladder applied to the upper and lower operation platforms of special vehicles for oil and gas exploration and development. The device is provided with two parallel and opposite tracks, and fixed wheels are arranged at the outer end parts of the two tracks; the upper part of each fixed wheel is provided with a rectangular connecting plate, and the lower part of the connecting plate is provided with a sliding wheel; the upper parts of the two rectangular connecting plates are welded with fixed pedals; the outer end part of the connecting plate is connected with two parallel ladder outer frames through a pin shaft; the outer frame of the ladder is provided with pedals, pedal pins and pedal limiting blocks. The effect is as follows: the movable ladder can be used for temporarily and repeatedly using the movable facilities and the fixed facilities limited by space for many times, can be quickly installed before being used, and can be quickly folded after being used, so that the purpose of repeatedly using the ladder for many times is achieved.
Description
Technical field
The utility model relates to the oil-gas exploration and development special vehicle, particularly a kind of in the special vehicle operation process the special-purpose ladder of operating desk up and down, be the convertible handy ladder of a kind of pedal.
Background technology
Along with the lifting of oil field development technology, various job that requires special skills vehicles are more and more.At present up and down the simple and easy ladder of vehicle operating desk is too in simply, and personnel are dangerous during ladder up and down, drops easily to cause injury to personnel.
The utility model content
The purpose of the utility model is: provide a kind of pedal convertible handy ladder; Be mainly used in MOVING STRUCTURE and space-constrained fixation means repeatedly uses temporarily repeatedly; And the back is realized the Fast Installation of ladder and is packed up before use, reaches the purpose of repeatedly using ladder repeatedly.
The technical scheme that the utility model adopts is: the convertible handy ladder of pedal; Mainly form by track, fast pulley, movable pulley, junction plate, fixed pedestal, bearing pin, ladder housing, pedal pin, pedal and padal stop; It is characterized in that: two parallel and relative tracks are arranged; Track is a channel-section steel, and two minor face inboards of channel-section steel are respectively to get on the right track and lower railway; Lower railway outer end at two parallel tracks is connected with a fast pulley respectively through holder, and fast pulley is on the top of holder; A rectangular junction plate is arranged on the top of two fast pulleys, be connected with a movable pulley in the inner bottom of junction plate through holder, movable pulley is in the bottom of holder, and movable pulley contacts with the lower railway of track; Upper level at the square junction plate of two block lengths is welded with a fixed pedestal; Face bonding is connected to top shoe on the inner of fixed pedestal, and the last plane of top shoe contacts with getting on the right track of track; Outer end at junction plate is connected with two parallel ladder housings through a bearing pin, and the ladder housing is rectangular steel plate; On two parallel ladder housings, equidistant pedal is arranged; One end of pedal is connected between two parallel ladder housings through pedal pin; Pedal can overturn along pedal pin; The equidistant respectively padal stop that is welded with in the inboard of two parallel ladder housings, when pedal be turned to blocked by padal stop after, pedal is horizontal.When not using ladder, lift the ladder housing and in two tracks, push away the ladder housing, junction plate drives fixed pedestal and inwardly slides along track; Pedal is inwardly overturn, and two ladder housings can orbital injection inside.
Be welded with an internal stop respectively in lower railway the inner of two parallel orbits; In the lower railway outer end of two parallel orbits, and be welded with an outer baffle block respectively in the inboard of fast pulley.Play position-limiting action, and guarantee that ladder ladder when transportation is moved can not move forward and backward.
The beneficial effect of the utility model: the convertible handy ladder of the utility model pedal; Can be used for MOVING STRUCTURE and space-constrained fixation means repeatedly uses temporarily repeatedly; And can realize the Fast Installation of ladder before use; Can draw in fast after the use, reach the purpose of repeatedly using ladder repeatedly.
Description of drawings
Fig. 1 is the convertible handy ladder structural profile of a utility model pedal sketch map, is lateral view.
Among the figure, 1-internal stop, 2-track, 3-outer baffle block, 4-fast pulley, 5-movable pulley, 6-top shoe, 7-junction plate, 8-fixed pedestal, 9-bearing pin, 10-ladder housing, 11-pedal pin, 12-pedal, 13-padal stop.
The specific embodiment
Embodiment 1: with a convertible handy ladder of pedal is example, and the utility model is done further explain.
Consult Fig. 1.The convertible handy ladder of the utility model pedal is made up of internal stop 1, track 2, outer baffle block 3, fast pulley 4, movable pulley 5, junction plate 7, fixed pedestal 8, bearing pin 9, ladder housing 10, pedal pin 11, pedal 12 and padal stop 13.
Two parallel and relative tracks 2 are arranged, and track 2 is a channel-section steel, and two tracks 2 must be straight, and error is in ± 1mm scope.Two minor face inboards of channel-section steel are respectively to get on the right track and lower railway.Lower railway outer end at two parallel tracks 2 is connected with a fast pulley 4 respectively through holder, and fast pulley 4 is on the top of holder.Be welded with an internal stop 1 respectively in lower railway the inner of two parallel orbits 2; In the lower railway outer end of two parallel orbits 2, and be welded with an outer baffle block 3 respectively in the inboard of fast pulley 4.
About top and the track 2 of two fast pulleys 4 parallel with a rectangular junction plate 7 is arranged; Inner bottom at junction plate 7 is connected with a movable pulley 5 through holder; Movable pulley 5 is in the bottom of holder, and two movable pulleies 5 contact with the lower railway of track 2 respectively.Upper level at the square junction plate 7 of two block lengths is welded with a fixed pedestal 8; Face bonding is connected to top shoe 6 on the inner of fixed pedestal 8, and the last plane of top shoe 6 contacts (gap that 1mm is arranged) with getting on the right track of track 2.Outer end at junction plate 7 is connected with two parallel ladder housings 10 through a bearing pin 9, and ladder housing 10 is rectangular steel plate.Equidistant six pedals 12 are arranged on two parallel ladder housings 10, and an end of pedal 12 is connected between two parallel ladder housings 10 through pedal pin 11, and pedal 12 can be along pedal pin 11 upsets.Equidistantly respectively in the inboard of two parallel ladder housings 10 be welded with six padal stops 13, when pedal 12 be turned to blocked by padal stop 13 after, pedal 12 is horizontal.
