If manual grinding and spraying are used, on the one hand, working at height is dangerous and labor-intensive, and on the other hand, manual work is inefficient. Therefore, there is an urgent need to provide a new solution. Summary of the Invention

[0031] Figure 3 This is a flowchart of the construction method of the large-scale surface grinding and spraying robot of the present invention. Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] See Figure 1 This invention provides a large-scale surface grinding and spraying robot and its construction method, which is used to automatically grind and spray large-scale surfaces, aiming to improve the construction efficiency of grinding and spraying. The large-scale surface grinding and spraying robot and its construction method are described below with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0035] See Figure 1 This diagram shows the structural schematic of the large-scale surface grinding and painting robot of the present invention during grinding operations. (See attached diagram.) Figure 2 This diagram illustrates the structure of the large-scale surface grinding and spraying robot of the present invention during spraying operations. The following is a related illustration. Figure 1 and Figure 2 The present invention describes a large-scale surface grinding and spraying robot.

[0036] like Figure 1 and Figure 2As shown, the high-rise surface grinding and painting robot of the present invention includes a climbing chain 21, climbing modules 22, a connecting frame 23, a grinding mechanism, and a painting mechanism. A pair of climbing chains 21 are provided, located on the outer side of the high-rise surface, which refers to a large-space concrete or steel structure surface, etc., and is the surface to be ground and painted. The number of climbing modules 22 is the same as the number of climbing chains 21, and the climbing modules 22 can move along the climbing chains. 21 moves up and down; the connecting frame 23 is connected to two climbing modules 22; the grinding mechanism is detachably connected to the connecting frame 23, the grinding mechanism includes a rotatable grinding disc 241, which can grind the surface of large and tall surfaces; the spraying mechanism is detachably connected to the connecting frame 23, the spraying mechanism includes multiple nozzles 251, and by selectively installing the grinding mechanism and the spraying mechanism on the connecting frame 23, grinding and spraying operations on large and tall surfaces can be realized.

[0037] In use, a grinding mechanism is first installed on the connecting frame 23, and the grinding disc 241 on the grinding mechanism is used to grind the large surface. After grinding, a spraying mechanism is installed on the connecting frame 23, and the nozzle is used to spray the large surface, thus realizing automatic grinding and automatic spraying, and improving the efficiency of grinding and spraying.

[0038] Furthermore, a rotatable sprocket is provided on the climbing module 22, which meshes with the corresponding climbing chain 21. The sprocket is then driven to rotate by a motor, thereby driving the climbing module 22 to move up and down along the climbing chain 21. Preferably, a control module and a power supply box are provided on the bearing surface (such as the ground or floor slab). The control module and the power supply box are respectively connected to the motor. The power supply box is used to provide power for the operation of the motor, and the control module is used to control the start, stop, and speed of the motor.

[0039] Furthermore, each of the two climbing modules 22 can be equipped with a motor mounted on the connecting frame 23. The motor is then connected to the corresponding sprocket via a synchronous belt and a synchronous pulley to drive the two sprockets to rotate synchronously, thereby enabling the two climbing modules 22 to move synchronously.

[0040] Preferably, a pair of climbing chains 21 are fixedly mounted on the top of the corresponding bearing surface and the tall surface. The bearing surface can be the ground. For example, one end of the climbing chain 21 can be fixed to the ground by anchor bolts or other connectors, and the other end of the climbing chain 21 can be fixedly connected to the top of the tall surface by a bracket or other structure. The tall surface can be a concrete wall or a steel wall. When fixing the climbing chain 21, the climbing chain 21 can be tensioned so that the climbing chain 21 reaches a certain tension, which can ensure the stability of the climbing module 22 moving up and down.

[0041] In one specific embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the height of one of the two climbing modules 22 is higher than that of the other climbing module. This causes the connecting frame 23 connecting the two climbing modules to be set at an angle.

[0042] Furthermore, the grinding mechanism has two grinding discs 241, and the two grinding discs 241 are set at different heights. The grinding discs arranged at an angle can meet the grinding requirements without dead angles.

[0043] The grinding mechanism also includes a power module that is driven and connected to the grinding disc 241, which drives the grinding disc 241 to rotate. This power module can be a motor driven and connected to the grinding disc 241, or it can be a motor driven and connected to the grinding disc 241 via a transmission mechanism (such as synchronous belt drive or gear drive). The two grinding discs 241 can share a single motor drive, or each grinding disc 241 can have its own dedicated motor drive.

[0044] The two grinding discs 241 are set at different heights, and the sides of the two grinding discs 241 partially overlap in the vertical direction, so that large and large surfaces can be ground comprehensively.

[0045] Furthermore, the two grinding discs 241 and the power module can be mounted on a grinding frame, which is installed on the connecting frame 23 via a pushing mechanism. This pushing mechanism applies force to the grinding frame to ensure that the two grinding discs 241 are tightly pressed against the large surface, thereby improving the grinding effect. The pushing mechanism is preferably an electric cylinder. The power supply box provides power to the pushing mechanism and the power module.

[0046] In one specific embodiment of the present invention, such as Figure 2 As shown, the spraying mechanism also includes a pressure pump and a material tank connected to the nozzle 251 via a feeding pipe. The pressure pump can pump the spraying material in the material tank to the nozzle 251, and spray it onto the surface of the large surface.

[0047] The spraying mechanism also includes a spraying bracket 252, which is detachably connected to the connecting frame 23. The spraying bracket 252 is provided with a plurality of nozzles 251 spaced apart, which can perform spraying operations on a certain range of surfaces. The nozzles 251 are oriented towards the large surfaces.

[0048] Furthermore, during the spraying operation, a top wall support 26 can be installed on the climbing module 22. This top wall support 26 is equipped with rotatable casters that contact the tall, large surface. In this way, the climbing module 22, on the one hand, abuts against the tall, large surface through the casters, and on the other hand, engages with the climbing chain 21 through the sprockets. This improves the stability of the climbing module 22 during movement, thereby providing stable support for the spraying operation of the nozzle 251 and ensuring the spraying effect.

[0049] The following describes the usage process of the large-scale surface grinding and spraying robot of the present invention.

[0050] When grinding and spraying concrete walls in large spaces, multiple robots can be selected to work simultaneously, depending on the area of ​​the concrete wall. For example, three robots can be selected to work at the same time, which can improve the efficiency of grinding and spraying. Multiple pairs of climbing chains can also be set up and fixed at construction intervals. After the three robots have completed the grinding of their respective areas, the first robot can be left behind and replaced with the spraying mechanism for spraying, while the other two robots are installed in the next construction position for grinding. This achieves a continuous operation of grinding and spraying. Alternatively, multiple robots can be used to grind simultaneously, and after the wall is ground, the spraying mechanism can be used for simultaneous spraying.

[0051] The present invention also provides a construction method for a large-scale surface grinding and spraying robot, which is described below.

[0052] like Figure 3 As shown, the construction method of the present invention includes the following steps:

[0053] Perform step S11, fix a pair of climbing chains to the outside of the tall surface in a parallel manner, and tension the climbing chains; then perform step S12;

[0054] Execute step S12 to engage the climbing module with the corresponding climbing chain; then execute step S13.

[0055] Execute step S13 to fix the connecting frame to the two climbing modules; then execute step S14.

[0056] Execute step S14: When grinding large surfaces, connect the grinding mechanism to the connecting frame, rotate the grinding disc, and simultaneously allow the climbing module to climb upwards along the climbing chain to complete the grinding operation on the large surfaces; then execute step S15.

[0057] In step S15, when spraying the large surface, the spraying mechanism is connected to the connecting frame, and the large surface is sprayed through the nozzle. At the same time, the climbing module is allowed to climb up along the climbing chain to complete the spraying operation on the large surface.

[0058] Furthermore, it also includes configuring a power module for the grinding disc, which drives the grinding disc to rotate. This power module is preferably an electric motor, which drives the grinding disc to rotate.

[0059] Furthermore, it also includes equipping the nozzle with a pressure pump and a material tank, using the pressure pump to pump the paint in the material tank to the nozzle.

[0060] Furthermore, it also includes: setting up a top wall support for the climbing module, allowing the top wall support to be slidably supported on a tall surface via casters.
