Description

Technical Field

[0001] The invention relates to the technical field of building exterior wall spraying, and in particular to a building exterior wall spraying robot. Background Art

[0002] With the development of social economy and the increase of population, there are more and more high-rise buildings in modern cities. The appearance of building surface spraying has become one of the focuses of people's attention on the appearance of the city. In recent years, with the acceleration of urbanization and the development of the construction industry, in the fields of urban infrastructure construction, real estate development and old house renovation, exterior wall coatings are one of the indispensable building materials, and the demand for building exterior wall spraying operations continues to grow.

[0003] Traditional high-rise building exterior wall spraying work is done manually by climbing the exterior wall scaffolding or riding in a high-altitude hanging basket. However, when performing high-altitude exterior wall spraying work manually, the strong airflow in the air makes it difficult for people to maintain balance with the hanging basket equipment, and casualties occur frequently. In the prior art, there is also a method of setting multiple adjustable support rods to contact the exterior wall. When the wind blows the hanging basket, at least one support rod of the shaking hanging basket contacts the wall. The assistance between the support rod and the wall can reduce the shaking amplitude and shaking frequency of the hanging basket. However, the spacing between each building exterior wall and the hanging basket is not equal. Therefore, workers need to adjust the position of the support rod so that the support rod is close to or far away from the wall, and finally achieves contact. Moreover, if one support rod contacts the wall, it will still cause the hanging basket to shake frequently. If multiple support rods can contact the wall, the shaking of the hanging basket can be greatly reduced. However, due to the different distances between the building's exterior wall and the hanging basket, it is also necessary to adjust the distance between the nozzle of the spraying mechanism and the building so that the nozzle can be in a preset optimal position to avoid the sprayed material from being difficult to adhere firmly to the wall due to the long distance. However, the above adjustment process takes a lot of time and requires manual operation, resulting in the workers still being in the hanging basket, which is too dangerous.

[0004] Therefore, it is necessary to design a building exterior wall spraying robot that can quickly adjust the position of the support rods and the spraying mechanism, and the entire adjustment process does not require manual operation. After the adjustment is completed, when the hanging basket shakes, multiple support rods can be brought into contact with the wall. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment: The present invention provides a building exterior wall spraying robot, such as Figure 1-3As shown, it includes a hanging basket 1, a mobile spraying mechanism 2, a mounting frame 3, a plurality of contact terminals 5, an elastic pushing mechanism 6, a locking mechanism 7 and a lifting motor 8. The mounting frame 3 is installed on the hanging basket 1 so as to be movable along the width direction of the hanging basket 1. The mobile spraying mechanism 2 is fixedly installed on the top of the mounting frame 3. The mobile spraying mechanism 2 is used to spray toward the outer wall of the building. A plurality of contact terminals 5 are fixedly installed on the mounting frame 3 through a plurality of elastic pressing mechanisms 9. The elastic pressing mechanisms 9 are used to apply an elastic force close to the outer wall of the building to the contact terminals 5. The elastic pushing mechanism 6 is fixedly installed on the hanging basket 1. The elastic pushing mechanism 6 is used to apply an elastic force close to the outer wall of the building to the mounting frame 3. The locking mechanism 7 is fixedly installed on the mounting frame 3. The locking mechanism 7 is used to connect the contact terminals 5 to the mounting frame 3 or to fix the mounting frame 3 to the hanging basket 1. When the hanging basket 1 is placed on the outer side of the building, the locking mechanism 7 locks the mounting frame 3 and the hanging basket 1, and at the same time, the locking mechanism 7 fixes the contact terminal 5 and the mounting frame 3, so that the hanging basket 1, the mounting frame 3 and the contact terminal 5 form a whole.

[0030] Then, it is necessary to adjust the position of the mobile spraying mechanism 2 and the contact terminal 5 so that the contact terminal 5 contacts the outer wall of the building. The mobile spraying mechanism 2 moves to a position where the outer wall of the building can be sprayed. At this time, the locking mechanism 7 switches the unlocking between the mounting frame 3 and the hanging basket 1, and the locking between the contact terminal 5 and the mounting frame 3 is ensured, so that the elastic pushing mechanism 6 can horizontally push the mounting frame 3 so that the contact terminal 5 contacts the outer wall of the building. That is, the whole process does not require an electric push rod to push, but uses elastic push. The advantage of elastic push is that it can only automatically push the contact terminal 5 to contact the wall, and after contact, due to the large overall weight of the hanging basket, the elasticity will not push the hanging basket to tilt. Compared with the use of an electric push rod to push, due to the inconvenience of observing on the roof due to the distance, it will cause the hanging basket to push and tilt, and this will cause the spray gun of the mobile spraying mechanism 2 to be in a tilted state, which will cause leakage during spraying. If workers are used to make adjustments, the positions of the mobile spraying mechanism 2 and the contact end 5 can be adjusted to just the right situation, but this goes back to the original problem, the workers need to be on the hanging basket, and the whole process is too dangerous.

[0031] After the contact terminal 5 contacts the outer wall of the building, the locking mechanism 7 switches the locking between the mounting frame 3 and the hanging basket 1, and the contact terminal 5 and the mounting frame 3 are unlocked. At this time, the contact terminal 5 can be pushed by the elastic pressing mechanism 9 and is in a free state, and the mounting frame 3 and the hanging basket 1 form a whole. After the mounting frame 3 is connected to the hanging basket 1, the elastic pushing mechanism 6 will not push the mounting frame 3 forward, and the contact terminal 5 will push the mounting frame 3 in the opposite direction through the elastic pressing mechanism 9, because this will cause the mounting frame 3 to move again. When the hanging basket 1 shakes, due to the pushing effect of the elastic pressing mechanism 9, when one side of the hanging basket 1 moves away from the outer wall of the building, the elastic pressing mechanism 9 immediately pushes the contact terminal 5 to move toward the outer wall of the building, compensates for this distance, and ensures that multiple contact terminals 5 are always in contact with the outer wall of the building. Through the contact of the contact terminal 5, when the hanging basket 1 swings toward the outside, the elastic pressing mechanism 9 extends, and when the hanging basket 1 swings inward, the elastic pressing mechanism 9 shrinks. The elastic pressing mechanism 9 is extended to ensure that the contact end 5 is in contact with the wall, so that friction is generated between the two to reduce the lateral swing, and the elastic pressing mechanism 9 is contracted so that the compressed elastic force can slow down the vibration and reduce the swing amplitude of the hanging basket 1. That is, the swing of the hanging basket 1 is reduced and the safety is increased.

[0032] Among them, in order to enable the locking mechanism 7 to meet the above-mentioned complex switching and the switching process is accurate, the locking mechanism 7 includes a rotating and swinging mechanism 7a, an extrusion plate 7b, a second card plate 7c and an elastic seat 7d. The rotating and swinging mechanism 7a is fixedly installed on the mounting frame 3, and the second card plate 7c and the elastic seat 7d can be installed on the mounting frame 3 for horizontal sliding. The rotating and swinging mechanism 7a is transmission-connected with the second card plate 7c and the elastic seat 7d. The rotating and swinging mechanism 7a is used to drive the elastic seat 7d and the second card plate 7c to switch in the wrong direction. The extrusion plate 7b is fixedly installed on the displacement end of the elastic seat 7d. The elastic pressing mechanism 9 is provided with a card plate 9a that can slide horizontally. The end of the second card plate 7c is provided with a card groove that is engaged with the card plate 9a. Figure 4 and Figure 5 As shown, when the extrusion plate 7b contacts the hanging basket 1, one side of the clamping plate 9a is located in the middle of the clamping groove, and at this time, the locking mechanism 7 locks the mounting frame 3 and the hanging basket 1 through the contact between the extrusion plate 7b and the hanging basket 1, and at the same time, the locking mechanism 7 fixes the contact terminal 5 and the mounting frame 3 through the clamping connection between the clamping plate 2 7c and the clamping plate 9a.

[0033] When the extrusion plate 7b is separated from the hanging basket 1, one side of the card plate 9a will be inserted deeper into the card slot, that is, the locking mechanism 7 switches the mounting frame 3 and the hanging basket 1 to unlock, and the contact end 5 and the mounting frame 3 are locked.

[0034] When the extrusion plate 7b continues to squeeze after contacting the hanging basket 1, the elastic seat 7d will be compressed, and the second clamping plate 7c will be separated from the first clamping plate 9a, that is, the locking mechanism 7 switches the locking between the mounting frame 3 and the hanging basket 1, and unlocks the contact end 5 and the mounting frame 3.

[0035] That is, the above-mentioned complex switching can be satisfied by the rotation switching of the rotating swing mechanism 7a. At the same time, only the mounting frame 3 and the hanging basket 1 are locked, and the contact end 5 and the mounting frame 3 are unlocked. The whole switching process is accurate, and the situation of simultaneous loosening will not occur, that is, it is avoided that a malfunction causes the worker to need to climb onto the hanging basket 1 for adjustment.

[0036] After the spraying of the building exterior wall is completed, the hanging basket 1 will be lowered to the ground, and the workers can dismantle the hanging basket 1. Therefore, there is no need to consider the problem of retracting the contact end 5 and the mounting frame 3, because there is no need to retract them.

[0037] In order to enable the rotation of the rotating swing mechanism 7a to drive the second clamping plate 7c and the elastic seat 7d to move in the wrong direction under the condition of satisfying the horizontal sliding, as shown in FIG. Figure 4 and Figure 6 As shown, the rotating and swinging mechanism 7a includes a rotating rod 7a1, a rotating seat 7a2, a hinged rod 7a3, an electric push rod 7a4, a sliding column 1 7a5 and a sliding column 2 7a6. The rotating seat 7a2 is fixedly mounted on the mounting frame 3, the rotating rod 7a1 is rotatably mounted on the rotating seat 7a2, the sliding column 1 7a5 is fixedly connected to the clamping plate 2 7c, the rotating rod 7a1 is provided with a waist-shaped hole 1 for sliding column 1 7a5, the sliding column 2 7a6 is fixedly connected to the elastic seat 7d, the rotating rod 7a1 is provided with a waist-shaped hole 2 for sliding column 2 7a6, one end of the hinged rod 7a3 is hinged to the rotating rod 7a1, and the other end of the hinged rod 7a3 is hinged to the output end of the electric push rod 7a4, and the electric push rod 7a4 is fixedly mounted on the mounting frame 3. When the electric push rod 7a4 is pulled, the electric push rod 7a4 will pull the hinge rod 7a3 to move, that is, pull the rotating rod 7a1 to rotate and swing along the rotating seat 7a2. The rotating rod 7a1 will drive the sliding column 1 7a5 and the sliding column 2 7a6 respectively, that is, the elastic seat 7d and the second clamping plate 7c will move in the wrong direction, and during the movement, the sliding column 1 7a5 and the sliding column 2 7a6 will slide along the waist-shaped hole.

[0038] like Figure 7As shown, the elastic seat 7d includes a guide post 1 7d1, a guide plate 7d2, a guide post 2 7d3 and a spring 1 7d4, the guide post 1 7d1 is fixedly mounted on the mounting frame 3, the guide plate 7d2 can be slidably mounted on the guide post 1 7d1, the guide plate 7d2 is fixedly connected to the slide post 2 7a6 through a connecting plate, the guide post 2 7d3 is slidably connected to the guide plate 7d2, the extrusion plate 7b is fixedly mounted on one end of the guide post 2 7d3, and a limiting plate is arranged at the other end of the guide post 2 7d3, and the spring 1 7d4 is used to apply an elastic force to the extrusion plate 7b away from the guide plate 7d2. The movement of the extrusion plate 7b is guided and limited by the guide post 1 7d1, and after the extrusion plate 7b contacts the hanging basket 1, as the slide post 2 7a6 continues to move toward the hanging basket 1, the spring 1 7d4 is compressed to play a buffering role.

[0039] like Figure 7 As shown, a friction plate 1a is fixedly arranged on the hanging basket 1, and the side of the extrusion plate 7b close to the friction plate 1a is rough. When the extrusion plate 7b contacts the friction plate 1a on the hanging basket 1, the friction between the two is used to lock, and with the movement of the sliding column 2 7a6, the locking will be tighter.

[0040] like Figure 5 As shown, a square hole is provided on the mounting frame 3 for the second clamping plate 7c to slide horizontally, that is, the second clamping plate 7c can slide horizontally through the square hole.

[0041] like Figure 5 As shown, the elastic pressing mechanism 9 includes a guide column 3 9b and a spring 2 9c, the guide column 3 9b is slidably connected to the mounting frame 3, the contact terminal 5 is fixedly mounted on one end of the guide column 3 9b, the clamping plate 1 9a is fixedly mounted on the other end of the guide column 3 9b, and the spring 2 9c is used to apply an elastic force to the contact terminal 5 away from the mounting frame 3. When the clamping plate 2 7c is separated from the clamping plate 1 9a, the elastic force of the spring 2 9c will push the contact terminal 5 to move toward the outer wall of the building.

[0042] like Figure 6 and Figure 8 As shown, the elastic pushing mechanism 6 includes an elastic telescopic rod 6a, a pressure sensor 6b and a connecting seat 6c. The elastic telescopic rod 6a is fixedly installed on the hanging basket 1, and the pressure sensor 6b is fixedly installed on the output end of the elastic telescopic rod 6a. The elastic force of the elastic telescopic rod 6a is used to push the mobile spraying mechanism 2 to move horizontally. When the contact end 5 collides with the outer wall of the building, the contact end 5 will transmit the impact force to the pressure sensor 6b through the elastic pressing mechanism 9 and the mounting frame 3. The pressure sensor 6b will detect the pressure signal, and the pressure sensor 6b will transmit the signal to the controller. The controller will control the rotating and swinging mechanism 7a in the locking mechanism 7 to work, so that the locking mechanism 7 switches the locking between the mounting frame 3 and the hanging basket 1, and unlocks the contact end 5 and the mounting frame 3.

[0043] like Figure 1 and Figure 3 As shown, the mobile spraying mechanism 2 comprises a transverse moving mechanism 2a, a monitoring device 2b and a spraying mechanism 2c, wherein the transverse moving mechanism 2a is fixedly mounted on a mounting frame 3, and the spraying mechanism 2c and the monitoring device 2b are both fixedly mounted on the displacement seat of the transverse moving mechanism 2a, and the transverse moving mechanism 2a is used to drive the spraying mechanism 2c to move horizontally, and the monitoring device 2b is used to monitor the outer wall of the building. The scene captured is transmitted to the controller by the monitoring device 2b, and the controller controls the transverse moving mechanism 2a and the spraying mechanism 2c to carry out mobile spraying, and automatically avoids the places where spraying is not required, such as windows, according to the scene. Lifting motors 8 are provided on both sides of the hanging basket 1, and the lifting motors 8 are connected to the slings on the roof. Working by the lifting motors 8 enables the hanging basket 1 to carry out lifting motion.

[0044] like Figure 2 and Figure 3 As shown, the mounting frame 3 includes a collection box 3a, and the contact end 5 is not fixedly connected to the collection box 3a. The collection box 3a can collect the oil splashed on the outer wall of the building by the mobile spraying mechanism 2 to prevent it from falling down and polluting the bottom building. And the position of the collection box 3a can be adjusted accordingly, so that the collection box 3a can be located closer to the outer wall of the building. The electric push rod 7a4 is fixedly installed on the collection box 3a, and the connecting seat 6c is fixedly connected to the collection box 3a. Through the function of the collection box 3a, multiple elastic pushing mechanisms 6 can be installed, and at the same time, a position for the electric push rod 7a4 to be installed is provided.

[0045] During use, when the hanging basket 1 is placed on the outer side of the building, the locking mechanism 7 locks the mounting frame 3 and the hanging basket 1, and at the same time, the locking mechanism 7 fixes the contact terminal 5 and the mounting frame 3, so that the hanging basket 1, the mounting frame 3 and the contact terminal 5 form a whole.

[0046] Subsequently, it is necessary to adjust the position of the mobile spraying mechanism 2 and the contact terminal 5 so that the contact terminal 5 contacts the outer wall of the building. The mobile spraying mechanism 2 moves to a position where it can spray the outer wall of the building. At this time, the locking mechanism 7 switches the mounting frame 3 and the hanging basket 1 to unlock, and the contact terminal 5 and the mounting frame 3 are locked, so that the elastic pushing mechanism 6 can push the mounting frame 3 horizontally, so that the contact terminal 5 contacts the outer wall of the building.

[0047] After the contact end 5 contacts the building outer wall, the locking mechanism 7 switches the mounting frame 3 to be locked with the hanging basket 1, and the contact end 5 to be unlocked with the mounting frame 3. At this time, the contact end 5 can be pushed by the elastic pressing mechanism 9 and is in a free state, and the mounting frame 3 and the hanging basket 1 form a whole. At this time, the painting work can be started.

[0048] The building exterior wall spraying robot is automatically pushed by the elastic pushing mechanism 6, that is, it can quickly adjust the position of the support rod and the spraying mechanism, and the entire adjustment process does not require manual operation. After the adjustment is completed, it is switched through the locking mechanism 7, and the locking mechanism 7 switches the locking between the mounting frame 3 and the hanging basket 1, and the unlocking between the contact terminal 5 and the mounting frame 3. At this time, the contact terminal 5 can be pushed by the elastic pressing mechanism 9 and is in a free state, and the mounting frame 3 and the hanging basket 1 form a whole. When the hanging basket shakes, the elastic pressing mechanism 9 extends to ensure that the contact terminal 5 contacts the wall, so that friction is generated between the two, reducing the side swing, and the elastic pressing mechanism 9 contracts, so that the compressed elastic force can slow down the vibration and reduce the shaking amplitude of the hanging basket 1. That is, the shaking of the hanging basket 1 is reduced and safety is increased.

[0049] The rotation switching of the rotating and swinging mechanism 7a can meet the above-mentioned complex switching. At the same time, it is only locked between the mounting frame 3 and the hanging basket 1, and unlocked between the contact end 5 and the mounting frame 3. The whole switching process is precise and will not be released at the same time, thus avoiding failures that cause workers to need to climb onto the hanging basket 1 for adjustment.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
