Description

Technical Field

[0001] The utility model belongs to the field of building construction equipment, and in particular relates to an auxiliary unloading platform. Background Art

[0002] During the construction process, due to the need for turnover materials to enter and exit, a protruding unloading platform is usually set up outside the building floor to carry materials and perform other construction operations during construction. The unloading platform is a temporary operating platform set up at the construction site, which can be mobile, floor-standing, cantilevered, telescopic, etc. Due to the limited load of the unloading platform, horizontal transportation machinery such as forklifts cannot be used. The transfer of materials needs to be sorted and transported from the work site to the vicinity of the unloading platform by manpower, and then transferred one by one to the unloading platform for unloading, or a tower crane is used to transport the materials to the high unloading platform, and then the materials are transferred to the work site by manpower. Due to the temporary nature of the unloading platform, it is very dangerous for operators to work at high altitudes on the unloading platform for a long time. When transporting heavy and high-center-of-gravity materials, there is a risk that the auxiliary unloading platform will detach from the slide rail and the materials will roll over, posing a great safety hazard to the operators. At the same time, due to the complexity of the construction environment, the assembly of the auxiliary unloading platform cannot be achieved in a one-time and refined installation. Therefore, an auxiliary equipment must be designed to help operators safely and efficiently transfer materials from the unloading platform to the interior of the floor.

[0003] A Chinese patent with authorization announcement number "CN217557740U" discloses a material transportation platform, which includes a support frame, a track and a conveyor vehicle; the support frame is arranged along a first direction, one end of the support frame is connected to a unloading platform, and the other end is connected to a construction area; the upper end of the support frame has a plurality of cross bars at a uniform height; the track is mounted on each cross bar and arranged along the first direction and the two ends extend to the unloading platform and the construction area respectively; the bottom of the conveyor vehicle is provided with rollers matching the track so that the conveyor vehicle can translate along the track, and the upper end platform of the conveyor vehicle is a flat loading surface.

Operators still need to work on the unloading platform for a long time. The transfer efficiency is low, labor-intensive and time-consuming, and the risk is relatively high.

[0005] In view of the above technical problems, this application proposes a solution. Utility Model Content

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection" and the like should be understood in a broad sense, and those of ordinary skill in the art can understand the specific meanings of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1 As shown, the auxiliary unloading platform described in the utility model includes a steel pipe frame 3, and the two ends of the steel pipe frame 3 are respectively mounted on the unloading platform 1 and the working platform 1, and the height of one end of the steel pipe frame 5 on the working platform 1 is higher than that of the other end on the unloading platform 1. The steel pipe frame 3 is composed of a transverse tube 22, a longitudinal tube 23 and a vertical tube 24, and they are fixedly connected to each other by a cross buckle 25. A full-length anti-tilt guide rail 5 is installed above the steel pipe frame 3. The anti-tilt guide rail 5 is an H-shaped steel, and the bottom of the anti-tilt guide rail 5 is fixedly connected to the steel pipe frame 3 by a U-shaped clamp 21. Full-length slide rails 4 are installed on both sides of the anti-tilt guide rail 5. The slide rails 4 are arranged parallel to the anti-tilt guide rails 5, and the bottom of the slide rails 4 is fixedly connected to the steel pipe frame 5 by a slide rail fixing device 20. The transverse tube 22, the longitudinal tube 23, the vertical tube 24 and the slide rail 4 are all made of steel pipe materials of steel pipe support frames commonly used on construction sites. The materials are easy to obtain, which facilitates the rapid installation of the overall structure of the auxiliary unloading platform. Figure 7 As shown, the slide rail fixing device 20 includes a fixed block 20-1 and a clamping block 20-2 which are rotatably connected. The cross tube 22 of the steel pipe rack 3 passes through the center of the fixed block 20-1 and the clamping block 20-2. An arc groove three 20-6 is provided on the top of the fixed block 20-1. The arc groove three 20-6 corresponds to the lower part of the steel pipe of the slide rail 4. A T-bolt 20-3 is passed through the side of the fixed block 20-1. A limit plate 20-4 is provided on the side of the clamping block 20-2. The T-bolt passes through the limit plate 20-4 and is tightened and fixed by a nut 20-5, so as to realize accurate and stable positioning and matching between the slide rail 4 and the cross tube 22 of the steel pipe rack 3.

[0031] An auxiliary unloading platform 6 is provided above the steel pipe rack 3. The auxiliary unloading platform 6 is composed of a horizontal tube 22 and a vertical tube 23, and they are also fixedly connected to each other by a cross buckle 25. The auxiliary unloading platform 6 is provided with a platform panel 6-1 on the top of the horizontal tube 22 and the vertical tube 23, which is used to carry materials and assist in the transportation of materials. Figure 2 The adjusting pulley 7 shown can slide on the slide rail 4, so that the auxiliary unloading platform 6 can move on the steel pipe rack 3 along the slide rail 4. The setting of the slide rail fixing device 20 allows the auxiliary unloading platform 6 to slide smoothly on the slide rail 4 without interfering with the cross pipe 22 of the steel pipe rack 3, and provides sufficient support to the slide rail 4, so that it will not be bent or deformed by the auxiliary unloading platform 6.

[0032] like Figure 2 , Figure 4 The adjusting pulley 7 shown includes a pulley fixing seat 9, the top of the pulley fixing seat 9 is provided with an arc groove 9-1 that cooperates with the horizontal tube 22 and the vertical tube 23 at the bottom of the auxiliary unloading platform 6, the bottom of the pulley fixing seat 9 is inlaid with a plane bearing 11, and a connecting shaft 11 is installed at the center position of the plane bearing 11. The top of the connecting shaft 11 is fixedly installed on the bottom of the pulley fixing seat 9, and its bottom is fixedly connected to the limit locking block 12.

[0033] The rotation connection on the connecting shaft 10 is as follows Figure 5 The rotating seat 13 shown includes a rotating seat body 13-1 in a cylindrical shape, a rotating shaft hole 13-3 is opened on the top of the rotating seat body 13-1, and the rotating shaft hole 13-3 corresponds to the connecting shaft 10. A stepped hole is opened at the bottom center of the rotating seat body 13-1, and an extrusion slope 13-4 is set in the middle of the stepped hole.

[0034] The rotating posts 13-2 are symmetrically connected to the outer side of the rotating seat body 13-1. There are two rotating posts 13-2, and a rectangular guide hole 13-5 is opened on the side of the rotating seat body 13-1 directly below each rotating post 13-2.

[0035] A pressure rod 14 is rotatably connected to the rotating column 13-2. The pressure rod 14 includes two symmetrically arranged cam portions 14-1, and a pressure rod portion 14-3 is connected between the two cam portions 14-1. A through hole 14-2 is opened on each cam portion 14-1, and the through holes 14-2 are rotatably matched with the corresponding rotating column 13-2.

[0036] like Figure 4 , Figure 5 As shown, a truncated cone-shaped adjusting seat 15 is provided inside the rotating seat 13, a screw hole is provided at the center of the adjusting seat 15, a threaded shaft 17 is installed in the screw hole, a clamping part 15-1 is provided at the truncated cone inclined surface position on the upper part of the adjusting seat 15, and the clamping part 15-1 is correspondingly matched with the extrusion inclined surface 13-4, and the clamping part 15-1 is used to clamp the threaded shaft 17. A U-shaped pulley seat 16 is fixedly connected to the bottom of the threaded shaft 17, a U-shaped guide wheel 18 is installed inside the U-shaped structure of the U-shaped pulley seat 16, and the U-shaped arc surface of the U-shaped guide rail 18 is correspondingly matched with the steel pipe shape of the slide rail 4.

[0037] The truncated cone-shaped adjustment seat 15 is symmetrically provided with guide posts 15-2 on the side of its cylindrical section, and the number of guide posts 15-2 is two, and the two symmetrical vertical side surfaces of the guide posts 15-1 correspond to the two vertical side surfaces of the guide hole 13-5, so that the adjustment seat 15 can slide up and down along the center of the rotating seat 13 inside the rotating seat 13 under the guidance and limitation of the guide hole 13-5. The top surface of the guide post 15-1 is an arc surface that contacts and cooperates with the cam portion 14-1.

[0038] like Figure 5 As shown, a threaded hole 13-6 is provided on the upper side of the rotating seat body 13-1, and the limit locking block 12 is arranged inside the rotating seat body 13-1 and corresponds to the position of the threaded hole 13-6. The horizontal cross section of the limit locking block 12 is a regular polygon, and the limit locking block 12 is concentric with the connecting shaft 10. A top screw 19 is installed inside the threaded hole 13-6, and the side of the top screw 19 close to the limit locking block 12 cooperates with the side of the limit locking block 12, so that the top screw 19 can limit the rotation of the limit locking block 12, thereby locking the rotation of the rotating seat 13.

[0039] In normal state, under the pressure of auxiliary unloading platform 6, pulley fixed seat 9 presses rotating seat 13 downward through plane bearing 11, and at the same time, extrusion slope 13-4 in the stepped hole of rotating seat 13 cooperates with the truncated cone slope of clamping part 15-1 of adjusting seat 15, extruding clamping part 15-1, so that clamping part 15-1 shrinks toward the center of adjusting seat 15, thereby clamping threaded shaft 17 installed in the center of adjusting seat 15, and reaching locking state, at this time, guide column 15-2 reaches the highest position in guide hole 13-5. Tighten top screw 19 deep into threaded hole 13-6 until top screw 19 contacts the side of limit locking block 12, at this time, limit locking block 12 is locked and cannot rotate, and rotating seat 13, adjusting seat 15, U-shaped pulley seat 16, threaded shaft 17, U-shaped guide wheel 18 are all locked due to the interrelated structures.

[0040] When it is necessary to adjust the height of the adjusting pulley 7, first loosen the top screw 19 in the direction away from the limit locking block 12, and then press the pressure rod portion 14-3 of the pressure rod 14 downward, causing the cam portion 14-1 to rotate around the rotating column 13-2. At this time, the contact position between the cam portion 14-1 and the arc-shaped top surface of the guide column 15-2 begins to transition from the proximal end to the distal end, so that the guide hole 13-5 begins to move upward under the guidance of the guide column 15-2, driving the rotating seat 15 to move upward, the clamping portion 15-1 disengages from the extrusion of the extrusion slope 13-4, and releases the threaded shaft 17. At this time, the threaded shaft 17 can rotate in the adjusting seat 15. Push the pressure rod 14-3 to rotate in the horizontal direction. Due to the limit of the rotating column 13-2, the rotating pressure rod 14 drives the rotating seat 13 to rotate, and under the limit of the guide column 15-2, drives the adjusting seat 15 to rotate. Since the central screw hole of the adjusting seat 15 cooperates with the threaded shaft 17, the rotation of the adjusting seat 15 will change the height of the adjusting seat 15 on the threaded shaft 17, thereby changing the distance between the rotating seat 13 and the U-shaped pulley seat 16, and finally adjusting the height between the auxiliary unloading platform 6 and the slide rail 4. After adjusting the distance, lift the pressure rod 14-3 in the opposite direction, the rotating seat 13-2 moves downward, the extrusion slope 13-4 re-extrudes the clamping part 15-1, and locks the rotation of the threaded shaft 17, and tightens the top screw 19 again, that is, the height adjustment of the auxiliary unloading platform 6 is completed.

[0041] During this process, since a plane bearing 11 is provided at the bottom of the pulley fixing seat 9, even if materials are placed on the auxiliary unloading platform 6, the top surface of the rotating seat 13 can easily realize the rotation of the rotating seat 13 around the connecting shaft 10 under the action of the plane bearing 11, thereby achieving the purpose of adjusting the height between the auxiliary unloading platform 6 and the slide rail 4.

[0042] like Figure 1 As shown, anti-tilt devices 8 are installed at both ends of the front and rear ends of the bottom center line of the auxiliary unloading platform 6. Figure 6As shown, the anti-tilt device 8 includes a fixed seat 8-1, the top of which is provided with an arc-shaped groove 8-6 that matches the horizontal tube 22 and the vertical tube 23 at the bottom of the auxiliary unloading platform 6, and the two ends of the bottom of the fixed seat 8-1 are fixedly connected with screw rods 8-2, which pass through the limiting wheel seat 8-3 and slide with the limiting wheel seat 8-3. The upper and lower ends of the sliding wheel seat 8-3 are both equipped with locking nuts 8-4 at positions corresponding to the two screw rods 8-2, and the locking nuts 8-4 are correspondingly matched with the screw rods 8-2.

[0043] Two relatively arranged limiting wheels 8-5 are rotatably connected below the limiting wheel seat 8-3, and the two limiting wheels 8-5 are installed on both sides of the H-shaped steel web of the anti-tilt guide rail 5. The circumferential wheel surface of each limiting wheel 8-5 contacts and cooperates with the lower surface of the H-shaped steel top wing plate of the anti-tilt guide rail 5, finally realizing the sliding cooperation between the anti-tilt device 8 and the anti-tilt guide rail 5.

[0044] The limiting wheel 8-5 is set between the upper and lower wing plates of the H-shaped steel, and due to the limiting of the H-shaped steel wing plate, the anti-tilt device 8 will not separate from the anti-tilt guide rail 5, and as the height between the adjusting pulley 7 and the slide rail 4 changes, the distance between the anti-tilt device 8 and the anti-tilt guide rail 5 also needs to be adjusted. At this time, it is only necessary to adjust the relative position of the locking nuts 8-4 above and below the limiting wheel seat 8-3 on the screw 8-2 and lock them, thereby realizing the matching adjustment of the distance between the anti-tilt device 8 and the anti-tilt guide rail 5, and making the circumferential wheel surface of the limiting wheel 8-3 always maintain contact with the lower surface of the H-shaped steel upper wing plate of the anti-tilt guide rail 5, thereby ensuring the relative position between the auxiliary unloading platform 6 and the slide rail 4, and making the U-shaped guide wheel 18 always contact with the slide rail 4 and will not separate from the slide rail 4, thereby achieving the purpose of preventing the auxiliary unloading platform 6 from overturning, improving the overall safety of the device, and ensuring the quality of the material.

[0045] like Figure 1 As shown, a winch base 26 is installed at the bottom of the steel pipe rack 3 near one end of the working platform 2, a winch 27 is installed above the winch base 26, a pulley bracket 28 connected to the anti-tilt guide rail 5 is installed on the winch base 26, a pulley 29 is installed on the pulley bracket, and the steel wire rope of the winch 27 is passed around the pulley 29 and fixedly connected to the anti-tilt device 8. The winch 27 is a prior art. When it is necessary to feed and lift the auxiliary unloading platform 6, the winch 27 is started to drive the steel wire rope to be wound on the winch 27, and through the pulley 29, the auxiliary unloading platform 6 is pulled. When discharging, the winch 27 rotates in the opposite direction. Due to the friction inside the motor of the winch 27, the auxiliary unloading platform 6 can be slowly released, thereby smoothly transporting materials and preventing the auxiliary unloading platform 6 from rushing out of the unloading platform 1 due to excessive speed.

[0046] The materials used in the utility model are mostly common materials on the construction site. When the utility model is needed, it can be quickly installed with very little manpower. When the utility model is no longer needed, it can also be quickly dismantled and reassembled. The disassembly and assembly are convenient and efficient, and it has strong adaptability to the construction environment. The steel pipe rack 3 is designed to be inclined. When discharging materials, the auxiliary unloading platform 6 and the material's own gravity can be used to transfer materials. When feeding materials, the winch 27 is used to rotate and drive the steel wire to wind, thereby raising the height of the auxiliary unloading platform 6. The operation is simple and convenient. Personnel do not need to stand on the unloading platform 1 for a long time to work. The safety is high, and manpower and resources are greatly saved. The utility model adopts an adjustable pulley design with an adjustable height, so that personnel can use it when assembling the auxiliary unloading platform as a whole. The rough-size assembly method is adopted without the need for refined installation. When the auxiliary unloading platform 6 has an inclination angle on the slide rail 4, which causes unstable material placement, the material placement can be stabilized by adjusting the adjusting pulleys 7 under the four corners of the auxiliary unloading platform 6. There is no need to disassemble and assemble the steel pipe rack for repeated adjustment, which improves the construction efficiency and further improves the overall adaptability of the auxiliary unloading platform to the construction environment. The utility model sets an anti-tilt device 8 and an anti-tilt slide rail 5 to cooperate with the auxiliary unloading platform 6 when transporting heavy and high-center-of-gravity materials. It ensures that the auxiliary unloading platform 6 is always on the slide rail 4, and will not accidentally overturn, causing the material to slip off the auxiliary unloading platform 6 and injure the operators, thereby improving the safety of the auxiliary unloading platform 6 and ensuring the quality of transported materials.

[0047] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
