Description

Technical Field

[0001] The present invention relates to the technical field of unloading platforms, and more particularly to a slide rail type material transport and unloading safety protection conveying platform device and a method for using the same. Background Art

[0002] Unloading platforms are temporary operating platforms and stands often erected on construction sites, typically used for material turnover. They come in various types: mobile, floor-standing, and cantilevered. To provide greater support strength, steel wire ropes are used to diagonally support the ends of the I-beams, creating a suspended load-bearing system. These platforms are fixed to the outer edge of the protruding structure on the lower floor. However, the wire ropes are connected to pre-recorded holes or embedded rebar rings in the upper structure, making their installation very inconvenient. Furthermore, cantilevered unloading platforms are immovable, requiring manual transport of construction materials from the upper floor to the platform. From there, vertical transport machinery like tower cranes are used to transfer these materials to the floor where construction is to be completed. These cantilevered unloading platforms rely on manual labor to collect and transport materials from the lower floor to the unloading platform. This is time-consuming and labor-intensive, resulting in low efficiency. Furthermore, these platforms pose safety risks such as falling objects and falls from height during elevated work. Summary of the Invention

[0003] 1. Technical problem to be solved by the invention

[0004] In response to the defects and shortcomings of the prior art, the present invention provides a slide-rail material transportation and unloading safety protection conveying platform device and a method for using the same. The present invention utilizes the movement of the bottom bracket to enable the transmission mechanism to drive the rotating shaft of the wire take-up box to rotate, so that the steel rope can be released and retracted, thereby ensuring that the steel rope always provides oblique support to the bottom bracket. With the installation coordination of the support frame and the I-beam frame, the steel rope can be fixedly connected to the support frame indoors, solving the problem of inconvenient installation of the steel wire rope and the superstructure, and there is no need to reserve holes or embed steel bar pull rings on the superstructure.

[0035] A transmission mechanism is provided between the take-up box 7 and the I-beam frame 2, and the transmission mechanism includes a toothed bar 10 and a bevel gear 11. The top of the toothed bar 10 is fixedly connected to the I-beam frame 2, the cross-section of the toothed bar 10 is trapezoidal, and a number of teeth are provided on the slope of the toothed bar 10. The tooth surface of the toothed bar 10 is meshed with the bevel gear 11, and the bevel gear 11 is meshed with the toothed bar 10. One end of the bevel gear 11 is fixedly connected to a worm 12, which is rotatably plugged into the inside of the plug-in slot 6. The bottom of the worm 12 is meshed with a worm wheel 13, and one end of the worm wheel 13 is fixedly connected to the middle shaft of the take-up box 7. The transmission ratio between the worm 12 and the worm wheel 13 is 4:1, and the center line of the worm wheel 13 is the same straight line as the center line of the middle shaft of the take-up box 7.

[0036] A limiting frame 14 is provided on the top of the connecting slot 6, and a steering wheel 21 is provided on the top of the limiting frame 14. The steel rope 8 is in contact with the surface of the steering wheel 21. The limiting frame 14 is movably connected to the surface of the steel rope 8. A limiting block 15 is provided at the connection point of the steel rope 8. Pull rods 16 are connected on both sides of the limiting frame 14. One end of the two pull rods 16 is movably connected to the surface of the steel rope 8, and the other end of the pull rod 16 passes through the limiting frame 14 and extends to the outside, and a spring 17 is provided on the rod body of the pull rod 16; the two ends of the spring 17 are respectively fixedly connected to one side end of the pull rod 16 and the outer wall of the limiting frame 14.

[0037] There are two groups of pull rods 16 which are staggered up and down. The springs 17 on the rods of the two groups of pull rods 16 are in a compressed deformation state.

[0038] A method for using a slide rail type material transport and unloading safety protection conveying platform device, the steps of which are as follows:

[0039] Step 1: When using the unloading platform, first fix one end of the I-beam frame 2 to the ground, then install and fix the steel support top 4 on the top of the I-beam frame 2, use the adjustment mechanism at the bottom of the steel support top 4 to make its top fit tightly against the top of the wall, then install and fix the support frame 3 and ensure that the protrusion at the bottom of the support frame 3 is inserted into the groove of the I-beam frame 2, so that the support frame 3 is connected to the I-beam frame 2 as a whole;

[0040] Step 2: After one end of the steel rope 2 is connected to the end of the connecting block 9, the load can be placed on the bottom plate 20, and then the external connection mechanism between the bottom bracket 1 and the I-beam frame 2 can be disconnected to push the unloading platform;

[0041] Step 3: When the bottom bracket 1 moves inward, the bevel gear 11 moves on the surface of the rack bar 10 and is pushed to rotate by it. The worm 12 rotates accordingly and drives the worm wheel 13 to rotate. The worm wheel 13 rotates the rotating shaft of the wire recovery box 7 to retract the steel rope 8 into the wire recovery box 7. Utilizing the characteristics of the worm 12 and the worm wheel 13, the rotating shaft of the wire recovery box 7 can only be rotated by rotating the bevel gear 11. When the steel rope 8 is perpendicular to the bottom bracket 1, the bottom bracket 1 will not continue to move.

[0042] When the bottom bracket 1 moves inward, the steel rope 8 will be retracted by the transmission mechanism into the wire take-up box 7, but the retraction speed of the steel rope 8 is lower than the release speed of the steel rope 8, which causes the steel rope 8 to be out of tension and unable to provide support. When the steel rope 8 is retracted, the compressed spring 17 will partially stretch the pull rod 16, and the pull rod 16 in the steel rope 8 in the limiting frame 14 will be pulled in two directions, so that the steel rope 8 will always remain in a taut state. When the angle between the steel rope 8 and the support frame 3 is less than 20 degrees, more than half of the bottom bracket 1 is already on the ground, and there is no need to require the steel rope 8 to provide a large tension. The limit block 15 provides support for the steel rope 8 when it passes by, and the steering wheel 21 redirects the tension of the steel rope 8 to avoid excessive friction of the tension on the top of the limit block 15.

[0043] The present invention utilizes the elastic force of the spring 17 to stretch the steel rope 8 in two directions, thereby preventing the steel rope 8 from being unable to be fully contracted and becoming loose when the bottom bracket 1 moves, thereby ensuring that the steel rope 8 is in a taut state to provide oblique support for the bottom bracket 1.

[0044] The present invention utilizes the movement of the bottom bracket 1 to enable the transmission mechanism to drive the rotating shaft of the wire take-up box 7 to rotate, so that the steel rope 8 can be released and retracted, thereby ensuring that the steel rope 8 always provides oblique support to the bottom bracket 1. With the installation cooperation of the support frame 3 and the I-beam frame 2, the steel rope 8 can be fixedly connected to the support frame 3 indoors, solving the problem of inconvenient installation of the steel wire rope and the superstructure, and there is no need to reserve holes or embed steel bar pull rings on the superstructure. The present invention is simple and efficient to use, does not require manual handling, and the unloading platform moves back and forth, which is safer.

[0045] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
