[0031] As Figures 2-9 shown, the photocatalytic formaldehyde removal coating preparation method is used to prepare the first embodiment of the coating:

[0032] A forklift frame welding tool, comprising a main frame 201, a horizontal rod frame 203 is fixedly arranged on the main frame 201 in a transverse direction, two side plates 301 are symmetrically arranged on the horizontal rod frame 203, a baffle 303 is fixedly arranged on the front end of the lower end of each of the two side plates 301, a bearing shaft I 302 is perpendicularly arranged on the outer side of each of the two baffles 303, an extension side plate 304 is connected to the rear end of the lower end of each of the two side plates 301, a bearing shaft II 305 is perpendicularly arranged on the rear end of each of the two extension side plates 304, a vertical rod frame 204 is arranged on the front end of the upper end of the main frame 201, a lifting seat 401 is slidingly arranged on the vertical rod frame 204, and a pressure shaft 402 is perpendicularly arranged on the front end of each of the two ends of the lifting seat 401.

[0033] When welding, the two load-bearing arms are placed on the left and right sides of the main frame 201 and are placed on the two groups of bearing shafts I 302 and bearing shafts II 305, at this time the two load-bearing arms are in contact with the two side plates 301, then the cross beam is pushed backward so that the cross beam abuts against the two baffles 303, at this time the cross beam and the two load-bearing arms can only move forward in the horizontal direction, forming a certain limit, then the front stop frame is placed on the cross beam, the lifting seat 401 is controlled to drive the two pressure shafts 402 to descend, and the two pressure shafts 402 are simultaneously pressed against the inclined surfaces on the left and right sides of the front stop frame, respectively, since the two pressure shafts 402 are symmetrically arranged about the center, when the two pressure shafts 402 are simultaneously pressed against the inclined surfaces on the left and right sides of the front stop frame, it indicates that the front stop frame is in a centered state, the front stop frame is pressed downward by the pressure shaft 402, thereby forming a limiting and fixing of the front stop frame, the cross beam and the two load-bearing arms, at this time the front stop frame is welded and fixed; the whole limiting process is convenient and fast, greatly improves the welding efficiency, and at the same time ensures the quality of the forklift frame.

[0034] It should be noted that the bearing shaft I 302 and the bearing shaft II 305 are rotatably connected, which facilitates the forward and backward pushing and pulling of the load-bearing arm, and the two pressure shafts 402 are rotatably connected, which facilitates the rolling of the two pressure shafts 402 on the inclined surface, so that the front stop frame is centered.

[0035] Further:

[0036] The vertical screw rod 403 is rotatably arranged on the vertical rod frame 204 and is threadedly connected with the lifting seat 401.

[0037] By rotating the vertical screw rod 403, the lifting seat 401 is threadedly driven to lift and slide, thereby driving the two compression shafts 402 to lift, so that the two compression shafts 402 are centrally pressed against the front support frame.

[0038] Further,

[0039] The bidirectional screw rod 205 is transversely rotatably arranged in the middle of the cross rod frame 203, and the two side plates 301 are threadedly connected with the two ends of the bidirectional screw rod 205.

[0040] By rotating the bidirectional screw rod 205, the two side plates 301 are simultaneously threadedly driven to move closer to or away from each other on the cross rod frame 203, thereby adjusting the width of the two side plates 301 to adapt to different specifications of the forklift frame formed by different widths between the two load-bearing arms.

[0041] Further,

[0042] The horizontal shaft 306 is transversely rotatably arranged at the lower end of the main frame 201, and the two extension side plates 304 are key slidably connected with the two ends of the horizontal shaft 306.

[0043] It should be noted that, in order to ensure the load-bearing capacity of the load-bearing arm, the edge of the load-bearing arm is downwardly turned over, and the lower end of the turned-over portion of a part of the load-bearing arm is not at the same height, so that the height of the load-bearing shaft II 305 needs to be adjusted when the turned-over portion is supported by the load-bearing shaft I 302 and the load-bearing shaft II 305, so as to ensure that the upper end surface of the load-bearing arm is in a horizontal state.

[0044] Therefore, the extension side plate 304 is connected with the side plate 301 by means of the shaft sleeve fixed on the extension side plate 304 and rotatably penetrating the side plate 301, so that the extension side plate 304 is rotatable on the side plate 301 through the shaft sleeve, thereby adjusting the horizontal height of the load-bearing shaft II 305, and then the horizontal shaft 306 is arranged to synchronously drive the two shaft sleeves to rotate through the key, thereby synchronously adjusting the horizontal height of the two load-bearing shafts II 305.

[0045] Further,

[0046] The worm gear I 307 is fixed in the middle of the horizontal shaft 306, and the worm I 308 is rotatably arranged on the main frame 201 and is in meshing transmission connection with the worm gear I 307.

[0047] By means of the self-locking function between the worm I 308 and the worm gear I 307, the rotation of the horizontal shaft 306 is locked, thereby locking the horizontal height position of the two load-bearing shafts II 305.

[0048] Further,

[0049] The middle part of the main frame 201 is slidably provided with a slide rod frame 502, and the front end of the slide rod frame 502 is fixedly provided with a front top plate 501. The rear end of the slide rod frame 502 is rotatably provided with a horizontal screw rod 503, which is threadedly connected with the main frame 201.

[0050] The horizontal screw rod 503 is rotated, the axial movement of the horizontal screw rod 503 is realized through the thread between the horizontal screw rod 503 and the main frame 201, the front and back movement of the slide rod frame 502 is driven in turn, so that the position of the front top plate 501 can be adjusted forward and backward, the front top plate 501 is then tightly pressed against the front stop frame, the front and back position of the front stop frame relative to the cross beam is limited and controlled, and further, the quality of the forklift frame is ensured.

[0051] Further:

[0052] A rubber layer is arranged on the front side of the front top plate 501, so as to avoid damaging the surface of the front top plate 501.

[0053] Further:

[0054] The lower end of the main frame 201 is rotatably provided with a support shaft 102, which is fixedly arranged at the upper end of the base frame 101. The middle part of the support shaft 102 is fixedly provided with a worm gear II 103. The main frame 201 is rotatably provided with a worm shaft II 202, which is in meshing transmission connection with the worm gear II 103.

[0055] The worm shaft II 202 is rotated, the worm shaft II 202 is in meshing transmission connection with the worm gear II 103, the main frame 201 is driven by the worm shaft II 202 to rotate around the support shaft 102, so as to adjust the state of the main frame 201, and the upper end of the main frame 201 is slightly inclined backward, so as to form the downward inclination of the two load-bearing arms, so that the load-bearing arms are more stable when being supported by the load-bearing shaft I 302 and the load-bearing shaft II 305 at the initial time.

[0056] Moreover, since the main frame 201 is inclined backward as a whole, the left and right inclined surfaces of the front stop frame pressed by the two pressing shafts 402 and the position limitation of the front stop frame by the front top plate 501 are not affected.

[0057] Further:

[0058] The outer surfaces of the load-bearing shaft I 302 and the load-bearing shaft II 305 are covered with rubber layers.

[0059] The outer surface of the pressing shaft 402 is covered with a rubber layer.

[0060] The rubber layer on the outer surface of the bearing shaft 302, the bearing shaft 305 and the pressing shaft 402 can form protection for the forklift frame, and the rubber layer on the pressing shaft 402 can also increase the friction between the pressing shaft 402 and the front bumper, thereby avoiding the front bumper moving back and forth.
