Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Examples
Referring to fig. 1 and fig. 2, for the drawing type foldable ladder stand structure of a mixer truck provided by the embodiment of the present invention, as shown in fig. 1 and fig. 2, the structure may include:
the ladder stand fixing seat comprises a ladder stand fixing seat 1, wherein one end of the ladder stand fixing seat 1 is connected with a side plate 2, and the side plate 2 is used for being fixedly connected with one side of a vehicle body A of the mixer truck and enabling the ladder stand fixing seat 1 to be in a horizontal state;
the crawling ladder movable seat 3 is in matched connection with the two first sliding ways 11 on the crawling ladder fixing seat 1 through a first pulley assembly 4, so that the crawling ladder movable seat 3 can linearly reciprocate in the horizontal direction along the crawling ladder fixing seat 1 and can limit the crawling ladder movable seat 3 to move in the vertical direction;
the first ladder stand 5 is connected with the two second slide ways 31 on the ladder stand movable seat 3 in a matching way through a second pulley assembly 6, so that the first ladder stand 5 can do linear reciprocating motion in the horizontal direction along the ladder stand movable seat 3 and can be turned downwards in the vertical direction to form a vertical state.
The cat ladder structure curb plate that this application embodiment provided can adopt the welded mode to link to each other with the cat ladder fixing base, and after the body coupling of curb plate and trucd mixer, can be so that the cat ladder fixing base forms the horizontality, the cat ladder sliding seat can locate the pull with the cat ladder fixing base mutually and make the structure, and when this cat ladder structure did not use, the cat ladder sliding seat can be accomodate into in the cat ladder fixing base, saves the space that occupies. When the ladder stand is needed to be used, the movable seat of the ladder stand is drawn out from the inner part of the fixed seat of the ladder stand to form a horizontal standing platform, so that a user can conveniently stand on the movable seat of the ladder stand to carry out related operation, and the personal safety of the user is ensured. This first cat ladder also adopts pull formula connected mode with the cat ladder sliding seat, when need not using, can be accomodate the inside to the cat ladder sliding seat by first cat ladder, when needs use, at first takes first cat ladder out along the horizontal direction in by the cat ladder sliding seat, then the upset downwards can form vertical state, supplies the user to scramble.
Because the height of the body of different mixer trucks is different, the required length of the ladder stand is different, and for this purpose, the embodiment of the application can provide at least one second ladder stand 7, and one end of the at least one second ladder stand 7 is connected with one end of the first ladder stand 5 far away from the second pulley assembly 6 through two hinges 8 on two sides of each ladder stand; the first ladder stand 5 and the second ladder stand 7 can be accommodated in the ladder stand movable seat when being folded through the two hinges. It can be understood that the second ladder stand and the first ladder stand can form a folding structure so as to be smoothly accommodated in the ladder stand movable seat. Specifically, the hinge is a spring hinge. Adopt the spring hinge can guarantee that first cat ladder and second cat ladder can extend smoothly. In order to meet the requirements of various ladder stand lengths, the second ladder stands comprise a plurality of second ladder stands, and two adjacent second ladder stands are connected through two hinges on two side surfaces of each second ladder stand to form foldable connection. In order to improve the safety of the user during treading and prevent slipping, the first ladder stand and the second ladder stand both comprise treading beams with square cross sections. The friction force between the sole and the cross beam of a user can be increased by adopting the square treading cross beam, and the shoe sole has excellent anti-skid performance compared with the traditional round cross beam.
