[0022] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4 The aluminum mold transmission device shown includes a base 1, a bidirectional motor 2 and a first wire-taking roller 3 arranged on the main shaft of the bidirectional motor 2. A movable frame 4 is fixedly connected to the base 1, and an extension bracket 5 is inserted into the movable frame 4. The first wire-taking roller 3 is fixedly connected to an extension rod 7 at the end away from the bidirectional motor 2. The extension rod 7 penetrates the movable frame 4, and a second wire-taking roller 8 is inserted into the outward extension through a pin shaft. The extension bracket 5 is located above the second wire-taking roller 8 and is provided with a terminal block 9. The movable frame 4 is close to the inner side of one side of the bidirectional motor 2 and is rotatably connected to a fixed pulley 10 near the top edge. A wire rope 20 is provided on the second wire-taking roller 8, and the wire rope 20 is connected to the terminal block 9 through the fixed pulley 10.

[0024] The specific working process is: the bidirectional motor 2 drives the second take-up roller 8 fixed on the extension rod to rotate, and the wire rope 20 is retracted into the second take-up roller 8 along the fixed pulley 10. Combined with the tension of the wire rope 20, the extension bracket 5 moves upward with the end of the wire rope 20 until it is adjusted to a suitable height.

[0025] like Figure 1 As shown, a retaining slot 15 is longitudinally provided in a linear array on the inner side of the movable frame 4 , and a retaining handle 16 for plugging into the retaining slot 15 is rotatably connected to the inner wall of one side of the extended bracket 5 .

[0026] The purpose of this design is that after the extended bracket 5 is adjusted to a suitable height, the rotating end of the fixing handle 16 rotates downward under the action of gravity and engages with the fixing slot 15 corresponding to the current height of the inner wall of the movable frame 4, thereby fixing the adjusted height of the extended bracket 5.

[0027] like Figure 3 As shown: the extended bracket 5 is located inside the movable frame 4 and is rotatably connected to a guide wheel 6, and the guide wheel 6 is slidably connected to the inside of the movable frame 4.

[0028] The purpose of this design is to complete the raising of the extended bracket 5 by rolling the guide wheel 6 on the inner wall of the movable frame 4, avoid direct contact between the movable frame 4 and the extended bracket 5, reduce friction, and speed up the height adjustment process of the extended bracket 5.

[0029] like Figure 1 As shown: a pulley frame 11 is fixedly connected to the extended bracket 5 near the upper end surface, a fixed pulley block 12 is arranged on the pulley frame 11 in an inverted triangle shape, a transport rope 13 is arranged on the fixed pulley block 12, one end of the transport rope 13 is connected to the first take-up roller 3, and a return spring 21 is connected between the other end and the base 1, and an aluminum mold transport bin 14 is arranged on the transport rope 13.

[0030] Specifically: the bidirectional motor drives the first take-up roller 3 to rotate, the transport rope 13 is retracted into the first take-up roller 3 and pulls the upper aluminum mold transport bin 14 through the fixed pulley group 12 to complete the position movement. Combined with the position setting of the aluminum mold transport bin 14 at the top and bottom of the transport rope 13 in this scheme, the aluminum mold transport bin 14 is transported to a suitable height, and the positions of the two aluminum mold transport bins 14 remain relatively unchanged, so as to achieve the effect of loading the lower aluminum mold transport bin 14 while unloading the upper aluminum mold transport bin 14.

[0031] like Figure 4 As shown: the upper surface of the aluminum mold transport bin 14 is fixedly connected with a hollow fork bolt 19 sleeved on the transport rope 13, and the hollow fork bolt 19 is threadedly connected with a notch nut 18.

[0032] The purpose of the design of this scheme is: by screwing the notch nut 18 on the hollow fork bolt 19, the inner surface of the hollow fork bolt 19 can be tightly fitted with the transport rope 13, thereby completing the fixation of the aluminum mold transport bin 14 on the transport rope 13, and when the height of the device is adjusted, the notch nut 18 can be loosened to complete the separation of the aluminum mold transport bin 14 from the transport rope 13, thereby ensuring the height adjustment process of the device.

[0033] like Figure 1 As shown: the movable frame 4 is rotated away from the bidirectional motor 2 and is connected to a weighted balancing tray 17.

[0034] The purpose of this design is to pile up waste sand or cement on the weighted balance tray 17 before transportation begins to reinforce part of the weight of the base 1 and avoid the device losing balance and being damaged due to excessive weight of the aluminum mold loaded in the aluminum mold transport bin 14.

[0035] like Figure 2 As shown: the fixed pulley 10 is located above the terminal block 9 in the vertical direction.

[0036] Further explanation of this solution: the fixed pulley 10 is arranged above the terminal block 9 to ensure that the wire rope 20 can drive the extended bracket 5 to move upward when it is retracted to the second take-up roller 8 to complete the height adjustment.

[0037] Working principle: the bidirectional motor 2 drives the second take-up roller 8 to rotate, and the wire rope 20 is recovered to the inside of the second take-up roller 8 through the fixed pulley 10 and drives the extended bracket 5 to slide upward until it reaches a suitable height. At the same time, the rotating end of the fixing handle 16 on the extended bracket 5 rotates downward due to the influence of gravity, and engages with the fixing slot 15 on the movable frame 4 corresponding to the height at this time, thereby completing the adjustment of the transportation height of the device.

[0038] The wiring diagram of the bidirectional motor 2 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the bidirectional motor 2 will not be explained in detail.

[0039] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
