[0018] A metal guardrail processing device comprises a belt conveyor and a positioning mechanism;

[0019] Among them, Figure 1 and 2 As shown, the belt conveyor includes a frame 11, two rollers 12 rotatably connected to the left and right sides of the frame 11, a conveyor belt 13 mounted on the two rollers 12, and a motor 14 installed at the lower front part of the frame 11. Figure 2 The middle reference numeral 14 specifically points to the output shaft of the motor 14. The output shaft of the motor 14 drives the roller 12 located on the right side to rotate through the first pulley belt assembly. The rotation of the roller 12 is used to drive the conveyor belt 13 to transport the metal guardrail. The front side of the upper end of the frame 11 is fixedly connected to a stop portion 15 straddling the front side of the upper end of the conveyor belt 13.

[0020] The positioning mechanism includes two horizontal baffles 31 arranged on the right front side above the conveyor belt 13, and an adjustment mechanism. The adjustment mechanism uses a spiral transmission method to adjust the distance between the two horizontal baffles 31.

[0021] For ease of description and understanding, Figure 8 The metal guardrail structure is shown, which has a horizontally extending railing, referred to as a horizontal railing, with an opening for connecting up and down on the horizontal railing, and a vertically extending railing arranged in a linear array in the left and right directions, referred to as a vertical railing, the opening for the vertical railing to pass through, and columns at both ends;

[0022] The metal guardrail without vertical railings is vertically placed on the conveyor belt 13 and between the two horizontal bars 31 to prevent the metal guardrail from falling. Then all the vertical railings are inserted into the horizontally extending railings in the left and right directions. At this time, all the vertical railings are against the upper end of the conveyor belt 13, and the preparation work is completed. The vertical railings are fixed together with the horizontal railings by welding or fasteners. Before fixing, the vertical railings can be slightly lifted as needed to make the vertical railings higher. When lifting, pads can be used to pad the lower ends of all the vertical railings. If there is no special need, the vertical railings can be against the conveyor belt 13. Because the metal guardrails are close to the front side of the belt conveyor, the operator can process them at the front side of the belt conveyor.

[0023] The belt conveyor includes a conveyor belt 13, and the two horizontal baffles 31 are arranged near the right front side of the conveyor belt 13, and the extension direction of the horizontal baffles 31 is the conveying direction of the conveyor belt 13;

[0024] For the convenience of description, the inner side is between the two horizontal baffle bars 31, and a pad block protruding inward is detachably fixedly connected to the left side of the inner end surface of the horizontal baffle bar 31, and the pad block extends with the horizontal baffle bar 31, and then the horizontal baffle bar 31 is used to support the column of the metal guardrail, and the pad block is used to pad the middle railing to increase the contact area and make the positioning more stable. Perforations can be set in the front and rear directions of the horizontal baffle bar 31, and the pad block is inserted into the perforation by friction. In this way, pads of different thicknesses can be selected according to the spacing between the column and the railing.

[0025] Furthermore, a vertical bar 32 is fixedly connected to the upper end of the horizontal bar 31, and the inner end surface of the horizontal bar 31 coincides with the inner end surface of the vertical bar 32. A pad is also fixedly connected to the inner end of the vertical bar 32 to abut against the uppermost horizontal railing. At this time, the lowermost horizontal railing is not blocked, and the lower horizontal railing and vertical railing are fixedly connected first.

[0026] Further, the adjustment mechanism includes a frame 22, and two double-ended lead screws 23 threadedly connected to the frame 22, the double-ended lead screws 23 extend forward and backward, the front and rear sides of the double-ended lead screws 23 have opposite thread rotation directions, and the rear sides of the two double-ended lead screws 23 are synchronously driven by a pulley belt assembly, and also includes a motor I24 for driving one of the double-ended lead screws 23 to rotate, the motor I24 is installed at the front end of the frame 22, a connecting arm 25 with a spiral transmission on the front sides of the two double-ended lead screws 23, and a connector with a spiral transmission on the rear sides of the two double-ended lead screws 23, and two horizontal baffles 31 are respectively fixed to the left end of the connecting arm 25 and the connector;

[0027] When the double-headed screw 23 rotates, the distance between the connecting arm 25 and the connector changes, thereby changing the distance between the two horizontal baffles 31. The double-screw solution has high adjustment accuracy and stability, and is suitable for positioning the longer horizontal baffles 31 in the vertically arranged metal guardrails with heavy clamping weight. If other solutions such as scissors-type or electric telescopic rods are used, they occupy a large space and are not as stable as the double-screw structure.

[0028] Furthermore, it also includes a telescopic cylinder Ⅰ21 for driving the holding frame 22 to rise and fall, the movable end of the telescopic cylinder Ⅰ21 is arranged upward, and the movable end of the telescopic cylinder Ⅰ21 is fixedly connected to the holding frame 22.

[0029] The telescopic cylinder I 21 is used to drive the horizontal barrier bar 31 to descend to the lower horizontal railing and the vertical railing, thereby exposing the upper horizontal railing and the vertical railing, so as to fix the upper horizontal railing and the vertical railing.

[0030] The connector includes a vertical seat 26 threadedly connected to two double-headed screws 23, a horizontal seat 27 fixedly connected to the lower end of the vertical seat 26, a motor II 28 installed on the horizontal seat 27, and a connecting block 29 fixedly connected to the upper end of the output shaft of the motor II 28, and the output shaft of the motor II 28 is set upward; the horizontal baffle 31 located on the rear side is fixedly connected to the left end of the connecting block 29.

[0031] Further, such as Figure 6 As shown, it also includes a placement mechanism, which includes: a telescopic cylinder II 41 with an upwardly disposed movable end, and a base 42 fixedly connected to the upper end of the movable end of the telescopic cylinder II 41, a telescopic cylinder III 43 with a rearwardly disposed movable end is installed on the base 42, a straddle 44 is fixedly connected to the rear end of the movable end of the telescopic cylinder III 43, a bending frame 51 is fixedly connected to the rear end of the straddle 44, a telescopic cylinder IV 52 with a leftwardly disposed movable end is installed at the front end of the bending frame 51, the movable part of the telescopic cylinder IV 52 passes through the straddle 44, a connecting piece 53 extending backward is fixedly connected to the left end of the movable end of the telescopic cylinder IV 52, a rod 54 extending rightward is rotatably connected to the rear side of the connecting piece 53, the rod 54 is located at the rear side of the bending frame 51, and the right side of the bending frame 51 is rotated A lead screw 55 is connected, a round steel 56 is fixedly connected to the right side of the bending frame 51, a motor III 57 is installed on the bending frame 51, the output shaft of the motor III 57 is fixedly connected to the lead screw 55, a first limit seat 58 is fixedly connected to the left side of the rear end of the bending frame 51, a second limit seat 58 is spirally driven on the lead screw 55, the second limit seat 58 is slidably connected to the round steel 56, the two limit seats 58 are arranged in a linear array in the left and right directions, the limit seats 58 are preferably concave in shape, that is, the upper and lower lanes are connected and the rear end is open, and the left and right ends of the limit seats 58 are provided with through holes for the rod 54 to pass through; the placement mechanism is generally located on the left side of the horizontal baffle 31 and on the front side of the belt conveyor; preferably, a rubber layer is provided on the outer surface of the rod 54.

[0032] After the metal guardrail is installed, start the telescopic cylinder III 43 to drive the limit seat 58 to move backward, start the motor III 57 to drive the lead screw 55 to rotate, adjust the distance between the two limit seats 58 so that the two vertical railings can be located in the two limit seats 58 respectively, then start the telescopic cylinder IV 52 to drive the rod 54 to move rightward and insert it into the two limit seats 58 in turn to surround the vertical railings. When the limit seats 58 continue to move backward, the metal guardrail leans back as a whole, then start the telescopic cylinder II 41 to make the two limit seats 58 drop to cooperate with the metal guardrail to fall down, after falling down, move the rod 54 to the left to pull out of the two limit seats 58, and finally raise the limit seat 58 to reset. After falling down, it is convenient to use the conveyor belt 13 to transport the metal guardrail to the next assembly line. During the falling down action, Figure 1 As shown, the abutment 15 is used to prevent the metal guardrail from sliding forward off the limit seat 58. This is because the rod 54 can rotate on its own. The rotation of the rod 54 can prevent the paint surface of the metal guardrail from being scratched.
