Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0025] The following embodiments can be understood as illustrating a part of the structure or method of the present invention individually, or as combining the embodiments to explain the broader structure or method of the present invention.

[0026] Example 1

[0027] An electric early warning self-climbing unloading platform, such as Figure 1-4 As shown, the system includes a control mechanism, a discharge box 1, a composite guide rail mechanism 7, a pull rod 4, a roller mechanism, a drive mechanism, and an overload warning mechanism. The composite guide rail mechanism 7 is fixedly connected to the surface of the building structure. The drive mechanism and the pull rod 4 are respectively installed on the left and right side walls of the discharge box 1. The pull rod has a roller mechanism installed at its end. The drive mechanism is engaged with the composite guide rail mechanism 7, and the roller mechanism is slidably connected to the composite guide rail mechanism 7. The overload warning mechanism includes a weighing sensor 8 and an alarm 9 for weighing the load of the discharge box 1. The weighing sensor 8 is installed at the bottom of the discharge box 1 or on the pull rod 4, and the alarm 9 is installed on the outer surface of the discharge box 1. The control mechanism is electrically connected to a power source via a cable and is electrically connected to the weighing sensor 8, the alarm 9, and the drive mechanism via wires.

[0028] In this embodiment, by fixing a composite guide rail mechanism to the surface of the building structure, the unloading box can move up and down under the drive of the drive mechanism, thereby realizing the unloading function. The composite guide rail mechanism is connected to both the drive mechanism and the roller mechanism. The drive mechanism drives the unloading box up and down, while the roller mechanism guides the unloading box and limits the drive gear of the drive mechanism, ensuring the meshing connection between the drive gear and the rack structure. The weighing sensor can be located at the bottom of the unloading box, with its top supporting the transported material through the box body, directly weighing the material. Alternatively, the weighing sensor can be mounted on a pull rod, indirectly determining the load of the unloading box by detecting the tension on the pull rod. When the load exceeds a preset warning value, an alarm is triggered to ensure the safety of the unloading process.

[0029] Example 2

[0030] Based on Example 1, this example discloses:

[0031] like Figure 1As shown, the unloading box 1 is a cubic shell with an open top or an open top and front end. When the front end is open, the unloading box is tilted backward after being connected to the composite guide rail mechanism. The shell includes a cubic frame welded from I-beams 5 and steel plates (not marked in the figure) welded inside the frame. The I-beams 5 at the bottom of the left and right side walls of the unloading box 1 extend forward and form motor mounting bases (not marked in the figure).

[0032] like Figure 1 As shown, the drive mechanism includes a drive motor 2 fixedly mounted on a motor mounting base, and the output shaft of the drive motor 2 extends forward and is fixedly connected to a drive gear 3.

[0033] Example 3

[0034] Based on Example 2, this example discloses:

[0035] like Figure 1 As shown, the pull rod 4 includes a first pull rod (not marked in the figure) and a second pull rod (not marked in the figure) arranged coaxially. The weighing sensor 8 is a circular load weighing device. The circular load weighing device is connected to the control mechanism via wired or wireless means. The circular load weighing device is coaxially fixedly connected between the first pull rod and the second pull rod. The other end of the first pull rod is rotatably connected to the rear end of the bottom side wall of the unloading box 1. The other end of the second pull rod is connected to a roller mechanism. The control mechanism is fixedly installed on the outer surface of the unloading box 1.

[0036] like Figure 1 , 4 As shown, the roller mechanism includes a bearing housing (not marked in the figure) integrally formed at the end of the second tie rod, a ball bearing (not marked in the figure) disposed in the bearing housing, and a rotating shaft (not marked in the figure) passing through the ball bearing and having an interference fit with the inner ring of the ball bearing. Rollers 42 are fixedly connected to both ends of the rotating shaft.

[0037] Example 4

[0038] Based on Example 3, this example discloses:

[0039] like Figure 2As shown, the composite guide rail mechanism 7 includes a convex guide rail. The inner sidewall of the convex guide rail is provided with a rack structure 71. The drive gear 3 is confined inside the convex guide rail and meshes with the rack structure 71. The output shaft of the drive motor 2 passes through the opening at the top of the convex guide rail (i.e., the output shaft and the drive gear form a convex structure that matches the inner cavity structure of the convex guide rail). The two shoulders of the convex guide rail are each integrally formed with a C-shaped guide rail 72. The two C-shaped guide rails 72 are respectively used to slide with the two rollers 42 of the roller mechanism, and the drive gear 3 and the rack structure 71 are always meshed by limiting the rollers 42. The second pull rod passes through the open end of the C-shaped guide rail 72. The two side walls of the convex guide rail extend outward and form a baffle 75 flush with the top of the convex guide rail.

[0040] like Figure 2 As shown, the back of the convex guide rail is integrally formed with a C-shaped groove 74, and the top wall of the C-shaped groove 74 is provided with a first bolt hole (not shown in the figure); the baffle 75 and the top side wall of the convex guide rail are provided with several sets of one-to-one opposing first limiting holes 73, such as Figure 4 As shown, the front end of the second pull rod is provided with a connecting plate. The connecting plate has a second limiting hole 41 that mates with the first limiting hole 73. Limiting plates (not shown in the figure) are configured around the first limiting hole 73 and the second limiting hole 41. When the limiting plates are inserted into the first limiting hole 73 and the second limiting hole 41, the roller mechanism and the composite guide rail mechanism are relatively fixed. That is, when the unloading box moves to a designated height, it can be locked by inserting the limiting plates, thus facilitating unloading or loading at this position.

[0041] Example 5

[0042] Based on Example 4, this example discloses:

[0043] like Figure 2 , 3As shown, the composite guide rail mechanism 7 is fixedly connected to the building structure surface via a connecting seat 10. The connecting seat 10 includes a U-shaped fixing seat, the bottom of which is provided with a second bolt hole 11. The second bolt hole 11 is used to connect with the free end of a U-shaped bolt (not shown in the figure) pre-embedded in the building structure. That is, the main body of the U-shaped bolt is pre-embedded in the building structure, and the two free ends of the U-shaped bolt protrude a certain length from the building structure surface. By pre-embedding several U-shaped bolts on the building structure surface, several connecting seats can be fixed, and the several connecting seats can connect the composite guide rail mechanism 7 to the building structure surface. The rail mechanism is fixed, and a drive gear and roller are inserted into the composite guide rail mechanism to connect the unloading box with the composite guide rail mechanism; the top of the U-shaped bolt is locked with a nut to achieve a fixed connection between the connecting seat and the building structure surface. The two side walls of the U-shaped fixing seat are integrally formed with outwardly folded clamping plates (left clamping plate 13, right clamping plate 12). The two clamping plates are engaged with the C-shaped clamping groove 74. A third bolt hole (not shown in the figure) is provided on the clamping plate. The clamping plate and the top wall of the C-shaped clamping groove are connected by bolts passing through the first bolt hole and the third bolt hole, and locked with a nut.

[0044] Example 6

[0045] Based on Example 5, this example discloses:

[0046] like Figure 1 As shown, the control mechanism is also equipped with a wireless signal transceiver module (not shown in the figure), and the control mechanism is connected to the staff's mobile phone control terminal (not shown in the figure) through the wireless signal transceiver module.

[0047] In this embodiment, with the above settings, workers can control the unloading box to move up and down and start and stop at a set position via a mobile phone control terminal. After starting and stopping, the unloading box is positioned by a limit plate to realize unloading or loading. All components of this invention can be prefabricated in the factory and assembled on-site during construction. After assembly, unloading can be achieved. After use, it can be disassembled and reused repeatedly.
