[0038] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the internal parts of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0040] Reference Attachment Figure 1-3 The present embodiment provides a material transport device for urban overpass construction, which includes: a frame 1, a material box 2 and a lifting mechanism. The lifting mechanism is arranged on the frame 1, and includes a lifting drive assembly 3 for lifting the material box 2 and a lifting guide assembly 4 for guiding the lifting process of the material box 2; the material box 2 includes an inner box 2.1 and an outer box 2.2, the outer box 2.2 has an open side wall 2.3, the inner box 2.1 and the outer box 2.2 are connected by a transverse driving assembly 5 and a transverse guiding assembly 6, the transverse driving assembly 5 is used to drive the inner box 2.1 to move transversely into and out of the outer box 2.2 at the open side wall 2.3 of the outer box 2.2, and the transverse guiding assembly 6 is used to guide the transverse movement process of the inner box 2.1.

[0041] By adopting the above technical solution, the lifting efficiency of the material box 2 is improved by the lifting drive component 3, and the stability of the material box 2 during the lifting process is improved by the lifting guide component 4, which can reduce the safety risks of the operation. When the material box 2 reaches the specified height, the inner box 2.1 is moved horizontally out of the outer box 2.2 by the transverse drive component 5, so that part of the weight of the inner box 2.1 falls on structures such as scaffolding. During the unloading process of workers, the material box 2 is prevented from falling outside, further reducing the safety risks of the operation; in addition, the transverse guide component 6 can improve the transverse smoothness of the inner box 2.1, making the use and operation of the material box 2 smoother and more convenient.

[0042] Reference Attachment Figure 2 The frame 1 of this embodiment includes a top plate 1.1 and four columns 1.2. The top plate 1.1 is located at the top of the columns 1.2 and is used to install the lifting drive assembly 3. The four columns 1.2 are distributed in a ring shape on the outer periphery of the material box 2 and are used to install the lifting guide assembly 4. The outer wall of the column 1.2 is provided with scale markings distributed along its own height, which are used to mark the lifting height of the material box 2, so that workers can check and judge the lifting height of the material box 2.

[0043] The lifting drive assembly 3 includes a winch 3.1, a first lifting rope 3.2, and a second lifting rope 3.3. Four sets of second lifting ropes 3.3 are distributed around the outer box 2.2 and connected to the outer box 2.2 via a lifting ring 2.4 located on the outer box 2.2. The top ends of the four sets of second lifting ropes 3.3 are connected by a connector 3.4 at the bottom end of the first lifting rope 3.2, which then connects to the winch 3.1 via the first lifting rope 3.2. The connector 3.4 can be configured in any suitable shape, such as a block-like structure with lifting points on both the top and bottom surfaces, the top lifting point being used to connect to the first lifting rope 3.2 and the bottom lifting point being used to connect to the second lifting rope 3.3. When materials need to be transported, the winch 3.1 is activated to reel in or lower the first lifting rope 3.2, which then drives the material box 2 up and down via the second lifting rope 3.3.

[0044] The lifting guide assembly 4 includes four guide columns 4.1 and four guide sleeves 4.2. The guide columns 4.1 extend in the height direction of the frame 1, that is, extend in the same direction as the columns 1.2 of the frame 1. The four guide columns 4.1 are distributed in a ring shape on the outer periphery of the material box 2 and are fixedly connected to the columns 1.2 of the frame 1; the guide sleeves 4.2 are mounted on the guide columns 4.1, and the outer walls are fixedly connected to the outer box 2.2.

[0045] When the winch 3.1 is started, the material box 2 will be moved in the height direction of the column 1.2 by the action of the second lifting rope 3.3 of the first lifting rope 3.2, and the outer box 2.2 of the material box 2 is connected to the guide sleeve 4.2. Since the guide sleeve 4.2 is restricted by the guide column 1.2 and can only slide along the extension direction of the guide column 1.2, the outer box 2.2 of the material box 2 can be guided or limited by the guide sleeve 4.2 and the guide column 1.2 at many places, which can ensure the stability of its lifting process and avoid skewing and causing materials to fall, causing safety accidents, etc.

[0046] Reference Attachment Figure 3 The transverse driving assembly 5 includes a slide 5.1, a transmission screw 5.2 and a driving motor 5.3. The inner box 2.1 is slidably connected to the outer box 2.2 through the slide 5.1; the transmission screw 5.2 is perpendicular to the open side wall 2.3 of the outer box 2.2, passes through and is threadedly connected to the slide 5.1; the driving motor 5.3 is provided on the outer box 2.2 and is used to drive the transmission screw 5.2 to rotate.

[0047] Since the transmission screw 5.2 is perpendicular to the opening side wall 2.3 of the outer box 2.2, when it is driven by the driving motor 5.3 to rotate, the slide 5.1 can move along its axial direction, thereby driving the inner box 2.1 to enter and exit the outer box 2.2 through the opening side wall 2.3.

[0048] It is worth noting that in order to prevent the slide 5.1 from rotating and affecting the smooth lateral movement of the inner box 2.1, the slide 5.1 and the outer box 2.2 should only have sliding freedom but not rotational freedom. For example, a slide groove 2.5 with a rectangular cross-section is dug on the inner side of the outer box 2.2, and the outer contour of the slide 5.1 is set to a rectangular cross-section structure, so that when the slide 5.1 is subjected to the force from the transmission screw 5.2, it can only move along its axial direction but cannot rotate around it.

[0049] During implementation, the transmission screw 5.2 can be rotatably arranged at the long end of the slide groove 2.5 through a bearing, and the drive motor 5.3 and the transmission screw 5.2 can be connected through a coupling.

[0050] The transverse guide assembly 6 includes two sets of guide rods 6.1 perpendicular to the open side wall 2.3 of the outer box 2.2. The outer box 2.2 is provided with a guide groove 6.2 extending in the same direction as the outer box 2.2. One end of the guide rod 6.1 slides through the guide groove 6.2, and the other end is connected to the inner box 2.1 through a connecting block 6.3.

[0051] The guide rod 6.1 is connected to the connecting block 6.3 to form a T-shaped structure, that is, the outer wall of the guide rod 6.1 is spaced apart from the outer wall of the inner box 2.1 to avoid affecting the sliding of the guide rod 6.1 in the guide groove 6.2.

[0052] The long ends of the aforementioned chute 2.5 and guide groove 6.2 both extend to the sidewall 2.3 of the opening. To prevent the inner box 2.1 from slipping off the outer box 2.2, this embodiment further provides a stopper groove 7 on the outer box 2.2, extending in the same direction as the guide groove 6.2. The long end of the stopper groove 7 is spaced from the sidewall 2.3 of the opening. The inner box 2.1 is connected to a stopper block 8 that slides within the stopper groove 7. During the lateral movement of the material box 2, the stopper block 8 can also slide within the stopper groove 7. However, because the long end of the stopper groove 7 does not extend to the sidewall 2.3 of the opening, the inner box 2.1 is prevented from slipping off the outer box 2.2.

[0053] To facilitate loading and unloading, the inner box 2.1 is opened on its side and provided with hinged door panels 2.6, adjacent hinged door panels 2.6 being connected by buckles. When loading and unloading is required, the hinged door panels 2.6 can be opened, making it convenient for workers to load and unload from the side.

[0054] In addition, the bottom of the frame 1 of this embodiment is dispersedly provided with moving wheels 9 and fixed legs 10, and the fixed legs 10 include a mounting plate 10.1, a leg screw 10.2 and a leg bottom plate 10.3. The leg screw 10.2 extends along the height of the frame 1, passes through and is threadedly connected to the mounting plate 10.1; the leg bottom plate 10.3 is provided at the bottom of the leg screw 10.2. The configuration of the moving wheels 9 enables the device to be moved to a specified position as needed, and when the device is moved to the specified position, the leg bottom plate can be lowered by screwing the leg screw 10.2. 10.3, the support foot plate 10.3 is used to increase the contact area with the ground and improve the support stability. The verticality of the guide column 4.1 in the present device can be corrected by adjusting the lowering height of different support foot plates 10.3 (determined by observing the levelness of the surface perpendicular to the guide column 4.1, for example, if the mounting plate 10.1 is welded and fixed perpendicular to the guide column 4.1, the levelness of the mounting plate 10.1 can be observed by a level bubble, etc. to determine the verticality of the guide column 4.1), thereby ensuring the smoothness and stability of the lifting of the material box 2 and avoiding skew.

[0055] In order to facilitate the screwing of the support leg screw 10.2, a screwing handle 10.4, a screwing disk and other components can be configured at the top end of the support leg screw 10.2.

[0056] When using this device to transport materials:

[0057] Push the frame 1 to the designated position, screw the support screw 10.2 and lower the support base 10.3 to ensure that the frame 1 is firmly supported and does not deviate during the material transportation process;

[0058] Load the material into the material box 2, start the winch 3.1 to reel in the first lifting rope 3.2, and move the material box 2 to the specified height using the first lifting rope 3.2 and the second lifting rope 3.3;

[0059] Start the drive motor 5.3 to move the inner box 2.1 out from the open side wall 2.3 of the outer box 2.2 and partially fall onto the scaffolding;

[0060] The worker opens the hinged door panel 2.6 to unload the material.

[0061] During implementation, a programmable controller (existing technology, no further description) can be constructed on the top plate 1.1, and the drive motor 5.3 and the winch 3.1 can be controlled by wireless remote control, making the operation more convenient.

[0062] Compared with the prior art, the present invention has at least the following beneficial effects: the lifting efficiency of the material box 2 is improved by the lifting drive component 3, and the stability of the material box 2 during the lifting process is improved by the lifting guide component 4, which can reduce the safety risks of the operation. When the material box 2 reaches the specified height, the inner box 2.1 is moved horizontally out of the outer box 2.2 by the transverse drive component 5, so that part of the weight of the inner box 2.1 falls on structures such as scaffolding. During the unloading process of workers, the material box 2 is prevented from falling outside, further reducing the safety risks of the operation; in addition, the transverse guide component 6 can improve the transverse smoothness of the inner box 2.1, making the use and operation of the material box 2 smoother and more convenient.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
