DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figure 1 and Figure 4 The present invention provides a technical solution: a multi-vehicle off-line conveying device for an assembly production line, comprising a right-angle tripod 141, a guide plate 14 which is arranged obliquely with the left side higher than the right side lower installed on the inclined surface of the right-angle tripod 141, and the guide plate 14 is lifted and installed by using the right-angle tripod 141, so that the assembled vehicle off the line can be guided out through the guide plate 14, and the right-angle tripod 141 is installed on the right end of the bottom plate 2 located on the right side, and then two placement plates 1 are respectively arranged on the upper sides of the two bottom plates 2 arranged on the left and right, and the placement plate 1 located on the right side is attached to the left end of the guide plate 14, and two horizontally arranged rectangular rods 4 are symmetrically installed between the two bottom plates 2, and the two rectangular rods 4 are used in combination to connect the two bottom plates 2, and a limiting block 11 which is an isosceles triangle with a cross section arranged in the form of a narrow upper part and a wide lower part and is arranged in the form of a longitudinal arrangement is installed on the placement plate 1 located on the left side. On the left side of the end, the wheels of the assembly vehicle placed on the placement plate 1 can be limited, and the upper end surface of the placement plate 1 is recessed downward to form a plurality of longitudinally arranged anti-skid grooves, so as to increase the friction coefficient of the placement plate 1 and provide good stability. When in use, the aerial hoist on the assembly line moves the suspended assembly vehicle to the top of the two placement plates 1, and then uses the aerial hoist to carry out offline operation of the assembly vehicle, so that the front and rear wheels of the assembly vehicle are respectively placed on the upper ends of the two placement plates 1. At this time, the two placement plates 1 can lift the assembly vehicle, and then disassemble the aerial hoist from the assembly vehicle, and then make the assembly vehicle drive to the right and enter the guide plate 14. Then, under the action of the guide plate 14, the assembly vehicle is driven to the ground to realize the offline transportation operation of the assembly vehicle. The assembly production line generally adopts a plate chain conveyor line. The structure and principle of the plate chain conveyor line are existing public technologies and will not be repeated here.

A first magnetic block 15 is installed on the bottom end of the inner part of the concave hole, and the vertical parts of a plurality of T-shaped columns 12 are evenly installed on the lower end of the placement plate 1, and then a second magnetic block 16 is set on the lower end of the vertical part of the T-shaped column 12, and then the transverse part of the T-shaped column 12 is inserted into the concave hole, so that the second magnetic block 16, which is arranged to repel each other with the first magnetic block 15, is located just above the first magnetic block 15, and the second magnetic block 16 located at the T-shaped column 12 is placed on the upper side of the first magnetic block 15. The limiting pieces on the outer side of the vertical part and the upper side of the horizontal part of the T-shaped column 12 are assembled to the card slot, so that the installation between the T-shaped column 12 and the rectangular column 13 is limited, and the purpose of convenient disassembly and assembly of the placement plate 1 is achieved, which is convenient for use. In addition, when the wheels of the assembly vehicle are placed on the upper end of the placement plate 1, the wheels of the assembly vehicle will impact the placement plate 1 and move the placement plate 1 downward, so that the T-shaped column 12 moves downward along the concave hole, and then the second magnetic block 16 moves downward. Because the second magnetic block 16 and the first magnetic block 15 are arranged to repel each other, the downward movement of the second magnetic block 16 will cause the first magnetic block 15 and the second magnetic block 16 to move downward. The repulsive force gradually increases between them, and the repulsive force will buffer the impact force generated by the wheels of the assembled vehicle to the placement plate 1, thereby realizing shock absorption and effectively reducing the probability of noise generation. The vertical part of the T-shaped plug 18 located at the outer end of the vertical part of the T-shaped column 12 can be inserted into the concave hole, and the T-shaped plug 18 can be attached to the upper end of the limiter, and the transverse part of the T-shaped plug 18 can be attached to the upper end of the rectangular column 13. The opening of the concave hole is blocked by the T-shaped plug 18, and the nickel part of the concave hole can be protected. The upper end surface of the first protective member is depressed downward to form a circular hole that penetrates the first protective member, and the first magnetic block 16 located at the lower side of the second magnetic block 16 is inserted into the concave hole. The protective member is arranged on the upper end of the first magnetic block 15, and the first protective member is used to prevent the first magnetic block 15 and the second magnetic block 16 from directly colliding with each other, so the safety is good. The design of the round hole, on the one hand, reduces the production amount of the first protective member, and on the other hand, does not affect the repulsive force generated between the first magnetic block 15 and the second magnetic block 16. The second protective member located on the lower side of the limiting member is arranged on the upper edge position of the transverse part of the T-shaped column 12, and the second protective member is used to prevent the transverse part of the T-shaped column 12 from directly colliding with the limiting member. The limiting member can adopt a retaining spring 17, the first protective member can adopt a rubber pad, and the second protective member can adopt a rubber round pad.
