DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0024] refer to Figure 1 As shown, a pull-out unloading platform has a length, width and height of 6000×2000×1200mm (cantilever end length 4.2m), including a platform bottom rail 1, a platform side rail 2, a platform guardrail 3, a material port springboard 4 and a pull-out side rail 5.

[0025] The platform bottom railing 1 is used to form the platform working surface at the bottom and to install and fix other railings. The platform bottom railing 1 is provided with platform side railings 2 at the feeding end and both sides, and the platform side railings 2 are used to protect the feeding end and both sides. The platform bottom railing 1 is provided with outward-facing platform guardrails 3 at the feeding end and both sides, and the platform guardrails 3 are outside relative to the platform side railings 2. The platform guardrails 3 are used to provide additional protection for the feeding end and both sides to prevent materials from falling outside the side rails.

[0026] The discharge end of the platform bottom rail 1 is hinged with a flip-over material port springboard 4, which is stored in the platform bottom rail 1 before and during hoisting. After the hoisting is completed, the material port springboard 4 is flipped and unfolded to be laid in the gap between the discharge end of the platform and the building to achieve walking transition. The discharge ends of the platform side rails 2 on both sides are provided with telescopic pull-out side rails 5, which are stored in the platform side rails 2 before and during hoisting. After the hoisting is completed, the pull-out side rails 5 are pulled out relative to the platform side rails 2 to extend the protection length of the platform side rails 2 and compensate for the protection of the discharge end.

[0027] The platform bottom rail 1 includes a bottom rail main beam 101, a bottom rail secondary beam 102 and a bottom rail panel 103. The bottom rail main beam 101 and the bottom rail secondary beam 102 are both cantilevered I-beams, the main beam is 16#, the secondary beam is 14#, and the thickness of the I-beam web is 6mm. There are two bottom rail main beams 101 arranged longitudinally, and the bottom rail secondary beams 102 are welded between the cantilevered ends of the bottom rail main beams 101. There are four bottom rail secondary beams 102 arranged transversely. The bottom rail panel 103 is welded to the bottom rail main beam 101 and the bottom rail secondary beam 102. The main beam and the secondary beam serve as a support frame to support the bottom rail panel to form a working surface.

[0028] The platform side rail 2 includes a side rail main keel 201, a side rail secondary keel 202 and a side rail panel 203. The side rail main keel 201 is arranged horizontally in the transverse or longitudinal direction and is made of 40*40*2.5mm square steel. The side rail secondary keels 202 are welded and connected between the side rail main keels 201. The side rail secondary keels 202 are arranged vertically and are made of 40*40*2.5mm square steel. A 1mm thick side rail panel 203 is welded and connected to the side rail main keel 201 and the side rail secondary keel 202. The main keel and the secondary keel serve as a supporting frame to support the side rail panel to form a protective surface.

[0029] The platform side rail 2 at the feeding end is provided with a feeding port 204, which is preferably in the shape of an inverted isosceles trapezoid (the main keel 201 of the side rail here needs to be arranged partially tilted), and the feeding port 204 facilitates the hoisted materials to enter the unloading platform. The platform side rail 2 at the feeding end is provided with a protective chain 205 located at the feeding port 204, and the protective chain 205 has two upper and lower sections. The protective chain 205 is used to form soft protection when not feeding, and the protective chain 205 can be removed when feeding.

[0030] The platform guardrail 3 includes a guardrail side beam 301, a protective net 302 and a tie rod 303. The guardrail side beam 301 is arranged in an inclined manner with a high outside and a low inside to form a structure that is easy to collect. The guardrail side beam 301 is a 40*40*2.5mm square steel. The bottom of the guardrail side beam 301 is hingedly connected to the platform bottom rail 1 through a hinge. A tie rod 303 is connected between the top of the guardrail side beam 301 and the platform side rail 2. The tie rod 303 is a Φ14 round steel. The platform bottom rail 1 is used for bottom support, and the tie rod 303 is used for top pulling to achieve the fixing of the guardrail side beam 301. The guardrail 3 can also be retracted by hinges later.

[0031] A protective net 302 is welded between the guardrail side beams 301. The protective net 302 is a 30*60mm diamond net. The guardrail side beams 301 are high outside and low inside at an angle of 15°. The protective net 302 on the guardrail side beams 301 forms a pocket shape that is easy to collect and prevents materials from falling at the edge.

[0032] The platform bottom rail 1 is hinged with the material port springboard 4 through a hinge, and the material port springboard 4 is turned over by the hinge. The material port springboard 4 rotates along the horizontal axis to be retracted inward or extended outward. The material port springboard 4 is a 4mm thick steel plate to achieve stable support. The springboard is turned over and stored in the platform as a whole, and turned outward to be used on the I-beam.

[0033] The pull-out side rail 5 includes a side rail cross bar 501, a fixed vertical bar 502, a socket vertical bar 503, a side rail net 504 and a pull-out sleeve 505. The pull-out side rail has a size of 2400×1200mm, and the side rail cross bar 501, the fixed vertical bar 502 and the socket vertical bar 503 are made of 50×50×2mm square tubes. Four pull-out sleeves 505 (two each on the upper and lower sides) are welded on the platform side rail 2, which are rectangular sleeves with a length, width, height and thickness of 100×60×60×3mm. The sleeve is hollowed out, with an aperture size of 50×50mm and a horizontal length of 100mm.

[0034] The side rail cross bar 501 is telescopically sleeved in the pull-out sleeve 505 to achieve the overall pull-out movement. The side rail cross bar 501 is welded with a fixed vertical pole 502 between the protective ends, and the side rail net 504 is welded between the side rail cross bar 501 and the fixed vertical pole 502. The side rail cross bar 501 and the fixed vertical pole 502 serve as a support frame to support the side rail net 504 to form a protection surface.

[0035] The end of the side rail crossbar 501 has a vertical opening with an aperture size of 40×40mm and a height of 50mm, which realizes the vertical sleeve function. A socket vertical rod 503 is inserted into the opening of the pull-out end of the side rail crossbar 501. The socket vertical rod 503 has a size of 40×40×1500mm (wall thickness 2mm), and a 60×60×3mm column cap is provided at the end to prevent it from falling off. When the socket vertical rod 503 is inserted into the side rail crossbar 501, the socket vertical rod 503 can form a clamping and limiting effect with the pull-out sleeve 505 to achieve the fixation of the side rail crossbar 501. The socket vertical rod 503 is clamped with the inner pull-out sleeve 505 (the second vertical rod position), so as to achieve inward retraction. The socket vertical rod 503 is clamped with the outer pull-out sleeve 505 (the first vertical rod position), so as to achieve outward release.

[0036] The side rail crossbar 501 includes an upper bar, a waist bar and a lower bar. The waist bar and the lower bar are telescopically sleeved in the pull-out sleeve 505, so that the upper bar is not restricted by the position of the pull-out sleeve and can be slightly higher than the height of the side rail, thereby improving the protective effect. The center point of the upper bar is 200mm away from the center point of the waist bar, with a hollow design. The waist bar is 1000mm away from the lower bar. The waist bar and the lower bar are filled with a 2mm wire mesh (40×40mm) and spot welded to the frame.

[0037] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.
