DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, what is described is only a part of the present invention, not all of it.

[0025] Reference Figure 1-6 , a beam elastic pin quick installation device, Figure 1 This is the general assembly drawing of the longitudinal beam elastic pin quick installation equipment. Figure 1 It can be seen that the longitudinal beam elastic pin quick installation equipment is mainly composed of a feeding rack 1, a roller 2, a pressing device 3, a high-pressure oil pipe 4, a material receiving rack 5, an electric hydraulic pump 6, and a pedal switch 7.

[0026] In order to improve production efficiency, multiple pipe longitudinal beams are placed on the feeding rack 1, and the design is as follows Figure 2 The feeding rack shown in the figure. Multiple pipe longitudinal beams can be placed on the inclined beam 9, and with the elastic feeding block 8, each time one pipe is pressed, the material is fed once. The rollers 2 are installed on the angle steel beams 10 and 24 to achieve rolling feeding of the device, reduce friction resistance, and improve transportation efficiency. Because the press-fitted longitudinal beam is a round tube, it is prevented from falling from the feeding rack 1 and the receiving rack 5 during transportation, and a special pipe blocking tube 11 is designed.

[0027] like Figure 3 The elastic feeding block 8 shown is made of a simple elastic feeding block 8 using a semicircular head bolt 14, a spring 15, a fixed square tube 16 and a nut 17. It is easy to make. When feeding is needed, it is only necessary to gently move the pipe longitudinal beam, and gravity compresses the spring so that the pipe longitudinal beam rolls over the upper part of the semicircular head bolt to the feeding roller. When the pipe longitudinal beam is manually moved, the elastic feeding block 8 can play a blocking role.

[0028] The press-fitting head 20 is designed with a limiting hole, so that when the elastic pin is installed, the exposed portion of the elastic pin can be the same depth as the limiting hole, ensuring that the exposed portion of all elastic pins is of the same length after installation, thereby improving product quality.

[0029] During the press-fitting operation, firstly, the elastic pin is set on the press-fitting positioning rod 19, and after the longitudinal beam hole of the pipe is aligned with the press-fitting positioning rod 19, the guide rod 18 is passed through the guide plate 13, penetrated from the longitudinal beam hole, and matched with the press-fitting positioning rod 19. When the foot switch 7 is stepped on, the electric hydraulic pump 6 is activated, and the high-pressure oil is sent to the oil cylinder 23. The piston rod of the oil cylinder 23 extends, driving the press-fitting head 20, the press-fitting positioning rod 19, and the guide rod 18 to push toward the longitudinal beam direction, so as to install the elastic pin.

[0030] When the pressing operation is completed, the guide tube 18 is pulled out, and the foot switch 7 is stepped on, the oil cylinder 23 is contracted, and the entire pressing part is contracted. In order to prevent the longitudinal beam from adhering to the pressing part, a limit plate 12 is designed on the feeding frame 1 to achieve the separation effect.

[0031] like Figure 4 As shown in the structural diagram of the press-fitting device, the press-fitting head 20, the flange sleeve 21, the flange seat 22, etc. are all connected by bolts to facilitate the replacement of the press-fitting parts.

[0032] like Figure 5 , Figure 6 As shown in the structural diagram of the material receiving frame, after the elastic pin of the longitudinal beam is installed, it is transported to the material receiving frame, pushing the longitudinal beam to roll along the inclined beam 25 to the support frame body 26. When the number of longitudinal beams reaches the packaging number, the longitudinal beams are supported by the support frame body 26, which is convenient for packaging and forklift transportation, thereby improving production efficiency.
