[0002] With the continuous acceleration of urbanization, more and more land is being developed into residential areas, shopping malls, hospitals, factories, etc. Although new high-rise buildings are constantly being built in cities, old buildings, especially old residential buildings, are still difficult to disappear in a short period of time. This is mainly because it is more difficult to develop old buildings. On the one hand, developers can earn less profit. On the other hand, the demolition of old buildings requires comprehensive consideration of the environment around the building, and the demolition is technically more complicated. Therefore, in the future, old buildings such as early residential buildings will still exist widely. Therefore, it is becoming more and more common to renovate old buildings. During construction, workers need to use scaffolding to climb up to renovate old buildings.

[0047] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] 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 specified and limited, the terms "set" and "connect" 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 connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0049] Reference Figure 1-5The present embodiment provides a material conveying device for old building reconstruction, which includes a mobile frame 1, a lifting assembly 2, a transverse movement assembly 3 and a material box 4. The mobile frame 1 includes at least a vehicle bottom plate 1.1, moving wheels 1.2 and a vehicle push handle 1.3. The moving wheels 1.2 are arranged at the bottom of the vehicle bottom plate 1.1, and the vehicle push handle 1.3, the lifting assembly 2 and the transverse movement assembly 3 are all arranged at the top of the vehicle bottom plate 1.1. The lifting assembly 2 and the transverse movement assembly 3 are connected through a loading platform 6. The vehicle push handle 1.3 is provided with an electric control key 5 for controlling the lifting assembly 2 and the transverse movement assembly 3; the material box 4 is movably arranged on the loading platform 6, and is lifted and lowered by the lifting assembly 2, or is transversely moved along the loading platform 6 by the translation assembly.

[0050] The above technical solution can solve the problems of low efficiency and poor construction safety caused by frequent up and down scaffolding 13 to take materials in current construction. By arranging the lifting assembly 2 and the lateral movement assembly 3 on the mobile frame 1, the tools or materials (hereinafter collectively referred to as materials) required by the workers can be transported to the specified height and the specified position, thereby improving the construction efficiency and ensuring the safety of the personnel.

[0051] Reference Figure 3 The lifting assembly 2 is mainly composed of a side guide rail 2.1, a vertical lead screw 2.2, a lifting servo motor 2.3 and a lifting block 2.4; the side guide rail 2.1 is installed on the outside of the loading platform 6, and its side opening faces the loading platform 6; the vertical lead screw 2.2 is rotatably installed in the side guide rail 2.1, and one end is connected to the lifting servo motor 2.3; the lifting block 2.4 is slidably installed in the side guide rail 2.1, and is sleeved on the outside of the vertical lead screw 2.2 and threadedly connected to it; in addition, the side end of the lifting block 2.4 passes through the side opening of the side guide rail 2.1 and is connected to the loading platform 6. It is known to those skilled in the art that the lifting block 2.4 is in sliding contact with the inner wall of the side guide rail 2.1 at least in one plane, so that when the vertical screw 2.2 is driven to rotate by the lifting servo motor 2.3, the lifting block 2.4 is limited by the inner wall of the side guide rail 2.1 and can only move along the axial direction of the vertical screw 2.2, and cannot rotate around the vertical screw 2.2, thereby smoothly realizing the lifting and lowering of the loading platform 6 and the material box 4.

[0052] The threaded connection between the vertical screw 2.2 and the lifting block 2.4 enables the lifting block 2.4 to move up and down along the vertical screw 2.2. The lifting servo motor 2.3 provides power. By controlling the rotation direction and speed of the motor, the lifting position of the loading platform 6 can be accurately controlled. The setting of the side guide rail 2.1 ensures that the lifting block 2.4 remains stable during the lifting process and will not deviate or get stuck. The advantage of this design is that the vertical screw 2.2 is driven by the motor to rotate, so that the stable lifting of the loading platform 6 is achieved, the unstable factors in the traditional lifting method are avoided, and the work efficiency and safety are improved. At the same time, the opening design of the side guide rail 2.1 enables the lifting block 2.4 to be connected to the loading platform 6, which simplifies the structural design and facilitates maintenance.

[0053] Reference Figure 4 The transverse movement assembly 3 includes a transverse guide rail 3.1, a transverse lead screw 3.2, a transverse movement servo motor 3.3 and a transverse movement block 4.4. The transverse guide rail 3.1 is arranged on the loading platform 6, and the top surface of the transverse guide rail 3.1 is open; the transverse lead screw 3.2 is rotatably installed in the transverse guide rail 3.1, and one end is connected to the transverse movement servo motor 3.3; the transverse movement block 4.4 is slidably installed in the transverse guide rail 3.1, and is sleeved on the outside of the transverse lead screw 3.2 and is threadedly connected to the transverse guide rail 3.1; in addition, the top end of the transverse movement block 4.4 passes through the top surface opening of the transverse guide rail 3.1 and is connected to the material box 4. It is known to those skilled in the art that the transverse movement block 4.4 is in sliding contact with the inner wall of the transverse guide rail 3.1 in at least one plane, so that when the transverse screw 3.2 is driven to rotate by the transverse movement servo motor 3.3, the transverse movement block 4.4 can only move along the axial direction of the transverse screw 3.2 due to the limitation of the inner wall of the transverse guide rail 3.1, and cannot rotate around the transverse screw 3.2, thereby smoothly realizing the transverse movement of the material box 4.

[0054] By adopting the above technical solution, the lifting and lifting and transverse movement of the material box 4 can be realized through the coordinated work of the lifting component 2 and the transverse movement component 3, so that the material in the material box 4 can be efficiently transferred from the ground to the scaffolding 13 where the workers are located, avoiding the trouble of frequently going up and down the scaffolding 13 in traditional construction, improving construction efficiency, reducing labor intensity, and ensuring personnel safety.

[0055] More preferably, the transverse guide rail 3.1 has a first long end and a second long end relative to each other. When the transverse block 4.4 is located at the first long end of the transverse guide rail 3.1, the material box 4 is at least partially located inside the loading platform 6; when the transverse block 4.4 is located at the second long end of the transverse guide rail 3.1, the material box 4 is at least partially located outside the loading platform 6. When the mobile frame 1 is moved to the side of the scaffolding 13, the material box 4 extending out of the loading platform 6 is just located on the scaffolding 13, making it convenient for workers to take materials.

[0056] In order to improve the smooth transfer of the material box 4, in this embodiment, side guide rails 2.1 and vertical screws 2.2 are respectively arranged outside a group of opposite sides of the loading platform 6, and at least two groups of lifting blocks 2.4 are used to enhance the support force of the loading platform 6 and improve the stability and smoothness of the loading platform 6 during the lifting process. In this case, the extension direction of the horizontal guide rail 3.1 should be considered to prevent the material box 4 from being blocked by the vertical guide rail and unable to move horizontally. Figure 3 Taking the square loading platform 6 as an example, side guide rails 2.1 and vertical screws 2.2 are respectively arranged outside a group of opposite side surfaces of the loading platform 6, and the first long end portion and the second long end portion of the transverse guide rail 3.1 are respectively arranged at another group of opposite side ends of the loading platform 6, so as to avoid obstruction of the lateral movement of the material box 4.

[0057] The transverse guide rail 3.1 can be externally arranged on the top of the loading platform 6, or it can be dug in the top surface of the loading platform 6. Similarly, multiple sets of transverse guide rails 3.1 and transverse screws 3.2 and other components can be arranged in parallel at the bottom of the material box 4. At least two sets of transverse blocks 4.4 can be used to enhance the supporting force of the material box 4, and improve the smoothness and stability of the material box 4 during the transverse movement. In particular, when part of the material box 4 extends out of the loading platform 6, multiple sets of transverse blocks 4.4 can be used to enhance the bearing capacity of the material box 4 and prevent it from falling.

[0058] Furthermore, a pump 8 and an air source tank 9 are also arranged on the mobile frame 1, and a buffer air bag 10 is arranged below the loading platform 6. The two ends of the pump 8 are respectively connected to the buffer air bag 10 and the air source tank 9, and the air source can be transmitted between the two. Of course, according to actual needs, an opening and closing valve 11 can be installed on the air pipe between the pump 8 and the buffer air bag 10. When the material box 4 is lifted, the pump 8 starts and sends the air source in the air source tank 9 to the buffer air bag 10. The buffer air bag 10 swells to support the material box 4, the loading platform 6, etc. in the event of an unexpected mechanical failure or the material box 4 and the loading platform 6 falling, thereby reducing the impact and structural damage. When the material box 4 is lowered to the vicinity of the buffer air bag 10, the pump 8 starts and sends the air source in the buffer air bag 10 to the air source tank 9. The buffer air bag 10 becomes deflated, so that the material box 4 can be lowered to the lowest point. The arrangement of the pump 8 and the air source tank 9 enables the buffer airbag 10 to be flexibly inflated and deflated, thereby improving the durability of the conveying device.

[0059] In addition, a buffer protection box 12 may be constructed under the loading platform 6. The top of the buffer protection box 12 is open, and the buffer airbag 10 is constructed in the buffer protection box 12. The buffer protection box 12 protects the buffer airbag 10 to prevent it from being pierced by foreign objects and leaking.

[0060] In addition, the material box 4 and the loading platform 6 can be connected in a detachable manner. For example, a limit basket 7 is constructed on the loading platform 6. The limit basket 7 can be made of a high-strength material. The limit basket 7 is connected to the transverse block 4.4, and the material box 4 is clamped in the limit basket 7. When the material box 4 is damaged, only the material box 4 can be replaced without disassembling the transverse block 4.4 and other structures, thereby improving maintenance efficiency.

[0061] Reference Figure 1 and 5The mobile frame 1 also includes a telescopic support leg 1.4, which is arranged on the vehicle bottom plate 1.1, and the telescopic support leg 1.4 can move along the thickness direction of the vehicle bottom plate 1.1; more specifically, the telescopic support leg 1.4 includes a support leg screw 1.41, a support leg screw sleeve 1.42, a support leg guide rod 1.43 and a pressure plate 1.44, the support leg screw sleeve 1.42 and the pressure plate 1.44 are respectively arranged on both sides of the vehicle bottom plate 1.1, and the support screw sleeve 1.42 is fixedly connected to the vehicle bottom plate 1.1; the support leg screw 1.41 passes through the vehicle bottom plate 1.1, one end is threadedly connected to the support leg screw sleeve 1.42, and the other end is rotatably connected (for example, connected by a shaft sleeve) to the pressure plate 1.44; the support leg guide rod 1.43 is fixedly arranged on the top of the pressure plate 1.44, and its top end passes through the vehicle bottom plate 1.1 and the support leg screw sleeve 1.42 in sequence.

[0062] When the mobile frame 1 is moved to the side of the scaffolding 13, the support screw 1.41 can be rotated to lower the pressure plate 1.44. Due to the limitation of the support guide rod 1.43, the pressure plate 1.44 can only move in the vertical direction. When the pressure plate 1.44 is pressed against the ground, the material box 4 can be transported. The design of the telescopic support leg 1.4 provides additional stability. When the device needs to be fixed in a certain position for operation, the telescopic support leg 1.4 can be extended to increase the support area to prevent the device from tilting or moving during operation.

[0063] For easy adjustment, an adjustment dial 1.45 is arranged at the top of the support screw 1.41, and the adjustment dial 1.45 is used to drive the support screw 1.41 to rotate. The setting of the adjustment dial 1.45 simplifies the operation process. The staff only needs to rotate the adjustment dial 1.45 to complete the height adjustment, without the need for additional tools, and the operation is convenient.

[0064] The method of using the device comprises the following steps:

[0065] S1. When workers use the scaffold 13 to climb up and carry out renovation work on old buildings, when they need to pass tools or materials to workers at the top of the scaffold 13, they push the mobile frame 1 to one side of the scaffold 13, and then the operator rotates the adjustment dial 1.45 to rotate the support foot screw 1.41, thereby driving the pressure plate 1.44 and the support foot guide rod 1.43 to move downward, so that the pressure plate 1.44 contacts the ground;

[0066] S2, put the tools and materials into the material box 4, and then use the lifting servo motor 2.3 to drive the vertical screw 2.2 to rotate, so that the vertical screw 2.2 drives the lifting block 2.4 to rise, thereby driving the loading platform 6 and the material box 4 to rise; then use the transverse servo motor 3.3 to drive the horizontal screw 3.2 to rotate, so that the horizontal screw 3.2 drives the transverse block 4.4 to move horizontally in the direction close to the scaffolding 13, thereby moving the material box 4 to the top of the scaffolding 13;

[0067] S3, the pump 8 is started to suck the gas in the gas source tank 9, and the gas is discharged from the other end into the buffer air bag 10 through the switch valve to protect the loading platform 6 and other components; the staff located above the scaffolding 13 can take out the tools and materials needed from the material box 4;

[0068] S4, the lateral servo motor 3.3 drives the lateral screw 3.2 to reset and rotate, so that the lateral block 4.4 is reset and the material box 4 returns to the top of the loading platform 6; the lifting servo motor 2.3 drives the vertical screw 2.2 to reset and rotate, so that the lifting block 2.4, the loading platform 6, and the material box 4 are synchronously lowered;

[0069] At the same time, the pump 8 is started to extract the gas in the buffer airbag 10, and discharge the gas into the gas source tank 9 from the other end, so that the buffer airbag 10 is stored in the buffer protection box 12;

[0070] S5. The operator resets and rotates the adjusting dial 1.45, so that the support foot screw 1.41 resets and rotates, thereby driving the pressure plate 1.44 and the support foot guide rod 1.43 to move upward, so that the pressure plate 1.44 is separated from the ground, so as to push the movable frame 1.

[0071] Compared with the prior art, the beneficial effects of the present invention are: providing a material conveying device for the renovation of old buildings, so that workers do not need to frequently go up and down the scaffolding 13 to take materials, thereby improving construction efficiency and reducing the safety risks and labor intensity of construction workers; through the coordinated action of the lifting component 2 and the transverse movement component 3, the material box 4 can be conveyed to a specified position at a specified height on the scaffolding 13; through the provision of a cushioning airbag 10, a pump 8, etc., the mechanical damage caused by the falling of the material box 4 and the loading platform 6 in the event of an unexpected failure can be reduced.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
