Abstract
The utility model discloses a roll-over ladder structure suitable for being assembled on the vehicle, relating to a ladder. The utility model comprises a n-shaped support frame which is vertically fixed with the foot platform of the vehicle and a ladder bed which is matched with the dimension of the transverse frame of the n-shaped support frame and connected with the n-shaped support frame. The essential structure of the utility model is that the ladder bed forms a similar triangle socket frame which comprises the oblique rods arranged on the both sides and the vertical bearing rods which are connected with each oblique rod. The transverse frame of each oblique rod is vertically provided with a plurality of foot boards at an equal interval. The lower ends of the both sides of the n-shaped support frame are provided with pin shafts which are hinged with the end of each vertical bearing rod to make the ladder bed rotate. The upper ends of the both sides of the n-shaped support frame are provided with latching sleeves which are matched with the positioning pins provided on each vertical bearing rod and the bottom bearing rod. The bottom bearing rod is provided with a spacer pin matched with the rubber pad which is arranged on the n-shaped support frame for the functions of supporting and spacing for positioning. Compared with the prior art, the utility model has the advantages of little extra space occupying, safety, reliability, convenience for the personnel to climb up and down.
Description
Technical field
The utility model relates to a kind of ladder, particularly is suitable for being installed in the upset ladder structure on the vehicle.
Background technology
Climbing car carrying platform or fixed platform often need be set up ladder for convenience.Now the ladder of Shi Yonging has portable and two kinds of fixed types, and portable ladder is moved inconvenience and can not be mobile with vehicular platform; And if the mode of fixed ladder vertical ground then is unfavorable for about the personnel,, when being used for vehicular platform, be easy to produce dangerous in the process of travelling if ladder with a slope has taken the space again.
Summary of the invention
At above-mentioned deficiency of the prior art, the purpose of this utility model provides a kind of upset ladder structure that is suitable for being installed on the vehicle.It can be fixed on vehicular platform or the fixed platform, the ladder that formation can be overturn.Have and do not take redundant space, safe and reliable, advantage that the staff is easy for going up and down, and can move with vehicular platform.
In order to realize above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
Be suitable for being installed in the upset ladder structure on the vehicle, it comprise can with the vertically fixing type bracing frame of vehicle operation platform and with the horizontal frame size match of type bracing frame and can connected ladder.Its constructional feature is, described ladder is formed by the brace of both sides with the perpendicular pole of each brace bonded assembly, end pole and formed seemingly interior triangle frame, a plurality of stretchers of the vertical equidistant placement of the horizontal frame of each brace.It is hinged and ladder is rotated that the lower end of described type bracing frame both sides is provided with the end of bearing pin and each end pole.The upper end of type bracing frame both sides is equipped with the lock sleeve of going up set locating dowel pin coupling with each perpendicular pole and end pole, and end pole is provided with that locating dowel pin and type bracing frame be provided with rises and support and the rubber pad of position-limiting action cooperates and locatees.
According to above-mentioned technical scheme, the connection handrail of can living on each brace of described ladder.
The utility model is owing to adopted above-mentioned structure, and ladder is connected on vehicular platform or the fixed platform by fixed mount, has avoided moving and loading and unloading the trouble of mobile ladder, and can move with vehicular platform.Ladder after the closure does not take the flat-bed space outerpace, can not cause potential safety hazard in the driving process of vehicle.Ladder after the expansion and ground form the gradient, made things convenient for the staff about.Compare with prior art, the utlity model has and do not take redundant space, safe and reliable, advantage that personnel are easy for going up and down.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
Description of drawings
Structural representation when Fig. 1 is the utility model closure state;
Fig. 2 is the right elevation of Fig. 1;
Structural representation when Fig. 3 is the utility model deployed condition;
Fig. 4 is application state figure of the present utility model.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the utility model comprise can with the vertically fixing type bracing frame 1 of vehicle operation platform and with type bracing frame 1 horizontal frame size match and can connected ladder 6.Ladder 6 is formed by the brace 9 of both sides with the perpendicular pole 4 of each brace 9 bonded assembly, end pole 8 and is formed seemingly interior triangle frame, a plurality of stretchers 10 of each vertical equidistant placement of brace 9 horizontal frames.It is hinged and ladder 6 is rotated around bearing pin 5 with the end of each end pole 8 that the lower end of type bracing frame 1 both sides is provided with bearing pin 5.The upper end of type bracing frame 1 both sides is equipped with lock sleeve 2, regains and expanded position with the closure that all set locating dowel pin 11 on each perpendicular pole 4 and the end pole 8 limits ladder 6.End pole 8 be provided with locating dowel pin 7 make upset after putting in place ladder 6 and rising of being provided with of type bracing frame 1 supported and the rubber pad 3 of position-limiting action cooperates and locatees.
When the utility model was closed, ladder 6 was recovered in the framed structure of type bracing frame 1, and with locating dowel pin 11 lockings on lock sleeve 2 and the perpendicular pole 4, ladder 6 can not routed up automatically, as shown in Figure 1.During expansion the locating dowel pin in the lock sleeve 2 11 is extracted, and ladder 6 is coincide around the rubber pad 3 of bearing pin 5 cws upset on locating dowel pin on the end pole 87 and type bracing frame 1, as shown in Figure 3.At this moment, ladder 6 exposes outside the vehicle platform, and stretcher 10 is parallel to the ground.To keep the stable of ladder 6 in the 11 insertion lock sleeves 2 of locating dowel pin on the end pole 8.Detouchable handrail 12 is installed on the brace 9 of ladder 6, ladder 6 just can use again.After finishing using, pull down handrail 12, the locating dowel pin in the lock sleeve 2 11 is extracted, closed ladder 6 is set locating dowel pin 11 and lock sleeve 2 cooperations on perpendicular pole 4, locking ladder 6.
The running condition of the utility model on vehicular platform cooked up rational installation site according to the vehicle usage space as shown in Figure 4.
Be pointed out that the utility model in addition except that the workplatform that is installed in vehicle, also can be fixed on other workplatform, as long as can realize that in the upset mode ladder structure closed and that launch all belongs to protection domain of the present utility model.
