And the chassis of a car is generally low, so the gradient of the climbing ladder must be small, otherwise the chassis will be scratched. Therefore, the car carrier in the prior art has a problem that the labor intensity of the operator is high and the climbing ladder on the car is too heavy. Moreover, it is not easy to carry while driving, and it is accompanied by certain dangers. The short climbing ladder makes it difficult to reach the climbing angle of the car.
[0003] In the prior art, a hydraulic ladder has appeared to solve this problem, but the hydraulic ladder also has problems such as complex equipment, increased operating costs, and space occupation.

Embodiment 1
[0027] combine Figure 1-Figure 7 , this embodiment provides a bearing shaft to pull the car ladder, from figure 1 As can be seen in the figure, it includes an outer slideway 1, a middle drawer ladder 2, and an inner drawer ladder, and the inner drawer ladder is provided with an inner drawer front ladder 4 and an inner drawer rear ladder 5.
[0028] The inner drawer ladder, the middle drawer ladder 2 and the outer slideway 1 are sequentially socketed. The flat plates of the inner draw ladder, the middle draw ladder 2 and the outer slideway 1 are made of steel plates with oblong holes. image 3 can be seen in.
[0029] From image 3 It can be seen from the figure that the two sides of the outer slideway 1 are provided with grooved slideway 11, the outer side of the lower end of the outer slideway 1 is provided with outer slideway rollers 8, and the side wall of the outer slideway 1 is provided with a limiter. Position hole, the end connected after being drawn out near the m...
Embodiment 2
[0036] This embodiment is an application embodiment, such as Figure 5-7 As shown, when you need to get on the car, first pull out the middle drawer ladder 2 and the inner drawer ladder from the outer slideway 1 at the same time (such as Figure 5 As shown), pull down the limit hole, lock the spring pin 9, and position the middle drawer ladder 2; then pull out the inner drawer ladder to the limit position, the pin shaft is limited to prevent serial movement, and the inner drawer ladder and the rear ladder 5 open (eg Figure 6 and Figure 7 Shown), fall on the ground, placed stably;
[0037] When it is necessary to retract the ladder, first fold the rear ladder 5 of the inner drawer onto the front ladder 4 of the inner drawer, and lift the front ladder 4 of the inner drawer and the rear ladder 5 of the inner drawer at the same time after overlapping, and draw the ladder inward 2. Push inward, and the pin shaft returns to the original position. Since the inner drawer roller 7...
Embodiment 3
[0039] The present invention also provides a transport vehicle, such as Figure 8 As shown, the bearing shaft in Example 1 is placed on the transport vehicle to pull it up the vehicle ladder, and the method in Example 2 is used to realize pulling. After the above-mentioned bearing shaft is installed and pulled onto the car ladder, it is convenient and reliable when the loaded commodity car is loaded. The climbing ladder for getting on the car is easy to operate, reduces labor intensity, increases the utilization space, and can be used without refitting the existing vehicle, while the climbing ladder in the prior art needs to refit the original vehicle to realize expansion and contraction.
[0040]The bearing shaft pulls the boarding ladder into three parts: the outer slideway of the boarding ladder 1, the middle extraction ladder of the boarding ladder 2, and the inner extraction ladder of the boarding ladder. The inner drawer of the boarding ladder is divided into the front ...

Abstract
The invention discloses a bearing pull-push boarding ladder and a transporting vehicle. The bearing pull-push boarding ladder comprises an external slide rail, a middle drawing ladder and an internaldrawing ladder; an internal drawing ladder front ladder and an internal drawing ladder rear ladder are arranged on the internal drawing ladder, wherein the internal drawing ladder, the middle drawingladder and the external slide rail are sleeved together in sequence; grooved slide rails are arranged on the two sides of the external slide rail; an external slide rail roller is arranged on the external side of the bottom of the lower end of the external slide rail; a limiting hole is formed in the side wall of the external slide rail; grooved slide rails are arranged on the two sides of the internal drawing ladder; a middle drawing ladder front roller and a middle drawing ladder rear roller are correspondingly arranged at the two ends of the middle drawing ladder; a spring pin matched withthe limiting hole is arranged on the side wall of the upper end of the middle drawing ladder; an internal drawing ladder roller is arranged at the upper end of the internal drawing ladder; an internaldrawing ladder limiting pin shaft is arranged on the internal side of the upper end of the internal drawing ladder; the internal drawing ladder front ladder and the internal drawing ladder rear ladder are hinged with each other; and a bracket is arranged in the connecting position of the internal drawing ladder front ladder and the internal drawing ladder rear ladder. The bearing pull-push boarding ladder has the advantages that the bearing pull-push boarding ladder facilitates loading operation of a commercial vehicle, the bearing pull-push boarding ladder is convenient and reliable, the operation is convenient, the labor intensity is reduced and the utilization space is enlarged.
Description
technical field [0001] The invention relates to a transport vehicle and parts thereof, in particular to a bearing shaft of a car transport vehicle and a ladder and a transport vehicle. Background technique [0002] With the increasingly fierce competition in the transportation industry market, the types of trailers are also increasingly subdivided. One of the important categories is the flatbed trailer for professional transport of cars. In order to facilitate transportation, a ladder is provided at the rear of the chassis. The manual operation of the workers is limited to the integrated structure of the ladder, so that the length of the ladder cannot be increased too much. And the chassis of a car is generally low, so the gradient of the climbing ladder must be small, otherwise it will scratch the chassis. Therefore, the car carrier in the prior art has a problem that the labor intensity of the operator is high during use, and the climbing ladder is too cumbersome. And it ...
