Surface crawling system for guiding a tool assembly on a construction surface.

The field of creation

The present invention relates to a system for guiding a tool device configured to perform work on a building.

The background of the creation

Work on building structures is associated with a process that involves the construction, alteration, repair, remodeling, improvement or demolition of a structure. For example, by strengthening and remodeling a building construction or a surface construction, where the purpose is to change or repair a building or the surface of a building. Redevelopment work includes alterations, improvements and/or repairs to a building site. Even the act of surface treatment aims to improve, change or protect a building surface. A structure can include building components, such as ships, floors, pavements or roads, etc. A treatment process of a building structure can be carried out via the surface of the building.

The treatment process of a construction can concern, for example, surface treatment, which can increase the ability to adapt to the surrounding conditions. Surface treatment can be a task in a renovation process. Different types of tools may be available to treat, for example, horizontal surfaces, such as roofs, ceilings and pavements, and vertical surfaces, such as wall constructions made of different building materials such as brick, stone, concrete, bitumen coating and slate, etc. the purposes can vary such as aesthetics improvements, repairs, protection, increasing wear resistance on different surfaces.

For example, a task could involve the treatment of a brick wall, where the construction's surface treatment includes the removal of old and damaged mortar. When mortar begins to crack, retreat and fall out of the joints, the old mortar must be chiseled out and puttyed with new mortar, which is a process called "repointing" in English.

Other tasks may relate to the strengthening and retrofitting of a construction, where the process is carried out via the construction surface. For example, installation of insulation in an existing building wall can take place from the outside or through the wall surface using

DK 202300052 U3 2 tool for blowing in insulation, which involves drilling holes in the outer wall and blowing the material in via a long, flexible hose. After the insulation process is completed, the hole is sealed.

When treating, repairing, strengthening and retrofitting a construction, manual work is often used, for example when using electric angle grinders to remove mortar in joints, drills to drill holes or painting machines to paint construction surfaces. These limitations pose a challenge for craftsmen.

Prolonged exposure to such mechanical vibrations can lead to disturbances in the vascular and neurological systems of the upper limbs, which poses a health risk for craftsmen.

In addition, the renovation process, for example of a building construction, may require scaffolding to ensure the safety of the craftsmen. Renovation processes take time and require craftsmen to closely monitor problems such as the edges of bricks when removing mortar from joints, or gaps when inserting masonry ties. During the renovation process, it is crucial that only the mortar is removed and the bricks are left undamaged. Treatment, repair, reinforcement or reconstruction via a construction through or on a construction surface can be a very expensive and time-consuming process. The costs for treating the construction surface, such as re-walling of joints, vary depending on the size of the area of the construction surface to be re-grouted.

The purpose of the creation

The object of the invention is to overcome these problems and to provide a system which is capable of carrying out construction work on or through a construction surface without posing a health risk to workers.

It is also an object of the invention to provide an agile system which can perform construction work on a larger area of construction on or through the construction surface without interaction or limited interaction from a craftsman, thereby reducing costs and time consumption related to the construction process.

Description of the production

The present invention addresses this by providing a

DK 202300052 U3 3 surface crawling system for carrying a tool device along a construction surface, where the surface crawling system comprises: - the crawling frame with a frame side, where the frame side in use is able to face the construction surface, where the crawling frame defines a working area in which the crawler frame carries at least one tool device, where the tool device in use is configured to perform construction work, where the tool device is configured to change position within the work area, and processes the construction surface according to a given processing sequence, - a rope system, where the rope system includes: - a first rope assembly having a first suspension member configured to be attached to a first fixation point relative to the construction surface, wherein the first rope assembly is attached to a first frame point such that in use the first rope assembly is capable of moving the crawler frame in a first direction towards or away from the first fixation point on the construction surface, and - a second rope device with a second suspension element configured to be attached to a second fixation point relative to the construction surface, the second rope device being attached to a second frame point, so that in use is the second rope device capable of moving the crawler frame in a different direction toward or away from the second fixation point on the construction surface, the second direction being different from the first direction, such that the surface crawling system is capable of moving the crawler frame in a crawling direction along the construction surface defined by the first direction and the second direction.

The surface crawling system can handle all treatment processes using tooling devices for treating structural surfaces or strengthening and rebuilding a structure. The surface crawling system is configured to move a crawler frame along a construction surface. The crawler frame includes at least one tooling device configured to process a construction surface. Alternatively, the crawler frame may include at least one tool device configured to penetrate a structural surface. The tool device can be an automated tool robot or the like. By using an automated tool robot, the treatment will be carried out with no or minimal interaction from a craftsman.

DK 202300052 U3 4

The tool device may be a device for removing old and damaged mortar, or the tool device may be a painting device. The tool device can also be another type of tool for other types of surface treatments. Alternatively, the tool device may be a device designed to penetrate the construction surface of the building, so that another tool device is able to perform a task behind the construction surface, such as re-insulating a building to improve the thermal properties of the building. Subsequently, other tool devices can be used to improve or repair the construction surface of the building. The surface-crawling system extends the working area of the tool device on the construction surface without interaction or limited interaction from a craftsman.

The construction surface can be a surface arranged horizontally, such as a street or a floor. Alternatively, the construction surface may be arranged as a vertical construction surface, such as a wall of a building structure. A building structure can have different types of construction that the crawler frame can be configured to crawl on. Alternatively, the construction surface can be arranged in an inclined position, where the construction surface can be an inclined surface, such as a roof. The construction surface can be approximately flat. Alternatively, the construction surface can be curved. Constructions can have many different surface shapes. The frame side of the crawler frame that faces the construction surface can be shaped according to the purpose of the task to be performed on the construction surface.

The crawler frame has a frame side which faces the construction surface during treatment of the construction surface. The frame side provides a work area in which the tool assembly can process the construction surface. The tool device can change location within the work area while it processes the construction surface in accordance with a predefined processing sequence. The construction surface within the work area is defined by the size and/or shape of the frame side.

When the processing of the construction surface is completed, the surface crawling system moves the position of the crawler frame to another work area on the construction surface, where the tool device processes another work area. The surface crawling system is configured to move the crawler frame within a crawl zone. The crawl zone includes a plurality of work areas where the tool device is able to process the construction surface. The crawler frame can be repositioned from one work area to another

DK 202300052 U3 work area, so that the tool device or devices are able to process the construction surface in each of the work areas separately.

The surface crawling system can be configured to move, push, pull, slide the crawler frame along the construction surface from one work area to another work area within the crawl zone of the surface crawling system.

The surface crawling system may include a rope system. The term rope bald is understood to mean that the term rope covers, for example, cables, wires, straps, toggles, chains, etc. The rope system can e.g. be a steel wire system. The rope system may comprise a first rope device and a second rope device. The first rope device is fixed to a first frame point on the crawler frame. The second rope device is attached to another frame point on the crawler frame. The second frame point is at a predefined distance from the first frame point.

The surface crawling system's crawl zone is defined by fixation points on or related to the construction surface. The surface crawling system defines the working position within the crawl zone using at least a first direction and a second direction relative to the first fixation point and second fixation point.

The first rope device has a first suspension element arranged at an opposite end of the first frame point on the crawler frame. The first suspension is attached to a first fixation point on or relative to the construction surface. The first fixation point is preferably arranged outside the crawling zone. During use, a distance is provided between the first fixation point and the first frame point, which defines the distance in the first direction.

The second rope device has a second suspension element arranged at an opposite end of the second frame point on the crawler frame. The second suspension element is attached to another fixation point on the construction surface. The second fixing point is preferably arranged outside the crawl zone. The second fixation point is at a predetermined distance from the first fixation point. A distance is provided between the second fixation point and the second frame point which defines the distance in the other direction.

The distances can be varied during use, to move the crawler frame with the tool device. The first fixation point and the second fixation point can approximately form a square creep zone. The crawler frame is configured to displace the tool assembly within the crawl zone.

DK 202300052 U3 6

The first rope device is configured to move the crawler frame along the construction surface in a first direction relative to the first fixation point on the construction surface. The first rope device moves the crawler frame along the construction surface in a first direction towards or away from the first fixation point on the construction surface.

The second rope device is configured to move the crawler frame along the construction surface in a different direction relative to the second fixation point. The second rope device moves the crawler frame along the construction surface in a different direction towards or away from the second fixation point. The second direction is different from the first direction.

The crawling frame can then be raised, lowered and shifted laterally in a crawling zone between the first and second fixation points when the distance between the fixation points and the crawling frame is varied. In this way, the crawling frame can then be raised, lowered and shifted laterally in the crawling zone defined by the first and second fixing points.

For example, the first and second fixation points may be located on a vertical surface, such as on a wall of a building structure. The first rope assembly can be attached to the first frame point on the first side of the top part of the crawler frame. The second rope device can be attached to another frame point on another side of the upper part of the crawler frame. The perimeter of the surface crawling system's crawling zone is defined by the fixation points on the construction surface. The crawling frame can then be raised, lowered and shifted laterally in a crawling zone between the first and second fixing points. The tool assembly can be configured to work within the crawl zone and treat the construction surface covered by the frame side.

Use of the surface crawling system reduces the cost of renovation. The surface crawling system is an agile system that is easy to handle, easy to install and easy to control. The surface crawling system is an agile system that handles a large surface area, where the surface crawling system is able to move the tool device from one working position to another working position without interaction or limited interaction from a craftsman. This reduces man hours and the workload on the craftsmen. Using the surface crawler

DK 202300052 U3 7 system also increases safety for craftsmen due to less manual work.

In a preferred embodiment, the rope system further comprises: - at least one supplementary rope device with a supplementary suspension element configured to be attached to a supplementary fixation point in relation to said surface, where said supplementary rope device is attached to a supplementary frame point, where said supplementary rope device is configured to move the crawler frame in a supplementary direction towards or away from the supplementary fixation point on the construction surface, where the supplementary direction is different from the first and second directions, so that the surface crawling system is able to move the crawler frame in a crawling direction along the surface defined by the first direction and the second direction and supplementary direction or directions.

The rope system can be provided as a first supplementary rope device and a second supplementary rope device. The first supplementary rope device may be attached to a first side point of the crawler frame. The first side point may be at a predefined distance from the first and second frame points.

The first supplementary rope device may comprise a first supplementary suspension element. The first supplementary suspension element can be attached to a first supplementary fixation point on or in relation to the construction surface. The first supplementary fixation point can be arranged outside the crawl zone. The first supplementary fixation point can be arranged such that the first supplementary fixation point is capable of expanding the crawling zone. The first additional fixation point may be arranged at a predetermined distance from the first and second fixation points.

The second supplementary rope device can be attached to another side point of the crawler frame. The second side point may be at a predefined distance from the first and second frame points and the first side point. The second supplementary rope device may comprise another supplementary suspension element. The second supplementary suspension element can be attached to another supplementary fixation point on the construction surface. The second supplementary fixation point can be placed outside the crawling zone. The second supplementary fixing point can be arranged so that the second supplementary fixing point is capable of expanding the crawling zone. The second additional fixation point may be arranged at a predetermined distance from the first and the second

DK 202300052 U3 8 fixation point and the first supplementary fixation point.

The first supplementary rope device may be configured to move the crawler frame along the construction surface in a first supplementary direction relative to the first supplementary fixation point. The first supplementary direction can be different from the first and second directions. The second supplementary rope device may be configured to move the crawler frame along the construction surface in another supplementary direction in relation to the second supplementary fixation point on or in relation to the construction surface. The second auxiliary direction may be different from the first and second directions and the first supplementary direction. The first supplementary direction and the second supplementary direction may be in different directions away from the crawler frame. The first supplementary rope device and the second rope device are capable of moving the crawler frame in different directions relative to the crawl zone.

The surface crawling system's crawling zone is defined by the fixation points on or related to the construction surface. The first fixation point, the second fixation point, the first supplementary fixation point and the second supplementary fixation point on the construction surface can form a polygonal shaped crawling zone defined by the position of the first supplementary fixation point and second supplementary fixation point in relation to the first fixation point and second fixation point. When the surface crawling system moves the crawler frame along the construction surface from one work area to another work area within the crawl zone, the surface crawler system moves the crawler frame by shortening or lengthening the ropes relative to each other. The surface crawling system is thereby able to move the crawler frame in a crawling direction along the construction surface in relation to the first and second directions and the first and second supplementary directions. The crawler frame can then be raised, lowered and shifted laterally in a crawl zone between the first fixation point, the second fixation point, the first and the second supplementary fixation point.

The rope system may comprise a third supplementary rope device which is different from the first and the second supplementary rope device. The third supplementary rope device can be used with or without the use of the first and second supplementary rope devices. The third supplementary rope device can be attached to a third frame point on the crawler frame. The third frame point may be at a predefined distance from the first and second frame points. The third supplementary rope device

DK 202300052 U3 9 can have a third supplementary suspension element. A third supplementary suspension element may be configured to be attached to a third supplementary fixation point. The third supplementary fixation point may be arranged at a predetermined distance from the first and second supplementary fixation points. The third supplementary rope device can be attached to a third frame point, so that the third rope device is able to move the crawler frame in a third supplementary direction towards or away from the third supplementary fixation point. The third supplementary direction is different from the first direction and the second direction. The third supplementary direction may also be different from the first supplementary direction and the second supplementary direction.

The third supplementary rope device may be configured to move the crawler frame along the construction surface in a third supplementary direction relative to the third supplementary fixation point. The third supplementary direction may be different from the first and second directions. The third supplementary direction can be placed between the first and second directions. The third supplementary direction may be different from the first and second supplementary directions of the first and second directions.

The third supplementary rope device can be used in operation together with the first and second supplementary rope devices. The third supplementary rope device can be placed between the first and the second rope device on the crawler frame. The third additional fixation point may be arranged in a position between the first and second fixation points. Alternatively, the third supplementary fixation point may be arranged in a position between the first and second supplementary fixation points.

The surface crawling system's crawling zone is defined by all fixation points. The additional fixing points and the additional rope devices provide a more agile and stable movement of the crawler frame. The use of the supplementary rope devices also reduces the mechanical vibrations in the crawler frame during use. The supplementary fixation points and the supplementary rope devices also ensure a robust and stable arrangement of the crawler frame during treatment of the construction surface.

When the surface crawling system moves the crawler frame along the surface from one work area to another work area, the surface crawler system moves the crawler frame by extending or reducing the distances between

DK 202300052 U3 10 the fixation points and the frame points. The surface crawling system is thereby able to move the crawling frame in the crawling direction along the surface in relation to the fixing points. For example, the surface of the structure to be treated may be a vertically arranged surface, where the first and second fixation points are located on the vertical surface of a wall or a building structure. The third supplementary fixation point can be located between the first and the second fixation point. The third supplementary fixation point can be placed in a higher position than the first and second fixation points. The first rope device can be attached to the first frame point on the first side of the top or front part of the crawler frame. The second rope device can be attached to another frame point on the other side of the top or front part of the crawler frame. The third supplementary rope device can be attached to the third supplementary frame point in the third supplementary rope device of the upper part or front part of the crawler frame. The third supplementary rope device can be configured to raise the crawler frame so that the upper part of the crawler frame is aligned with the first and second fixation points. The surface crawling system's crawling zone is defined by the fixation points on the construction surface. The crawler frame can then be raised, lowered and shifted laterally in the crawl zone defined by the first main, second main and third auxiliary fixation points. This arrangement gives an approximately square crawling zone.

Alternatively, the surface crawling system may include all five rope devices. The crawling frame can then be raised, lowered and shifted laterally in a crawling zone defined by the first and second fixation points, as well as the first, second and third supplementary fixation points which are arranged relative to the construction surface. This provides a surface crawling system that has a crawling frame with flexible mobility. The surface crawling system provides a movable crawling frame that can be moved easily and quickly on the construction surface. The surface crawling system provides a stable and mobile work station for a tool assembly.

In yet another preferred embodiment, each of the rope devices comprises a rope and a rope winch and a motor for driving the rope winch, in which the rope is attached to the rope winch at one end and the suspension element is attached to an opposite end of the rope so that the suspension element is capable of being attached to the fixation point or the supplementary fixation point.

DK 202300052 U3 11

Each of the rope devices, the first and second rope devices, and the additional rope device(s) may comprise a rope and a winch and a motor for driving the winch. Each rope is attached to the winch at one end. A suspension element is attached to the other end of each rope opposite the winch. The suspension element is configured to be attached to a fixation point on the construction surface related to the respective rope device. The rope can be wire rope, chain rope or other types of rope. the rope pulleys are capable of moving the crawler frame in a crawling direction by pulling or releasing the ropes from the respective rope devices. As the surface crawling system moves the crawler frame along the surface from one work area to another work area, the surface crawler system moves the crawler frame by winding the ropes in and out relative to each other. The distance between the frame point and the fixation point can be varied by winding and unwinding the respective rope. The surface crawling system mediates the forces related to magnitude and direction between fixation points and the crawler frame. The surface crawling system is thereby able to move the crawler frame in a crawling direction along the surface in relation to the first direction and the second direction.

In a further preferred embodiment, at least one intermediate element is fixed in relation to said frame side of said crawling frame, so that said intermediate element rests against said surface when the frame side faces the surface.

The intermediate element is fixed in relation to the frame side of the crawler frame and faces the construction surface. The intermediate elements rest against said surface and ensure a stable working position for the crawler frame when a work task is carried out. When the intermediate elements rest against said surface, the crawling frame is supported by the construction surface. The intermediate element can be provided with an anti-slip material on the surface of the intermediate element facing the structural surface to be treated, to ensure a firm grip on the surface to be treated.

In yet another preferred embodiment, the at least one intermediate element comprises a movable part.

The intermediate element may comprise one or more moving parts. The moving parts can be rotatable. The moving parts can provide a smooth and easy movement of the crawling frame when it is moved along the surface. The moving parts

DK 202300052 U3 12 may include steering wheels or roller wheels or the like.

In a further preferred embodiment, the surface crawling system comprises a control unit configured to drive each of the motors related to the respective rope devices such that the rope system moves the crawling frame in a predetermined crawling direction.

The control unit controls each of said motors to drive the respective winches.

The control unit controls the rope system by winding the ropes in and out, so that the control unit moves the crawling frame in a predetermined crawling direction within the crawling zone. The control unit controls the movement of the crawler frame by changing the length of the ropes relative to each other as each of the motors drives each respective rope winch. The control unit can be remotely controlled by a cable or wireless connection.

In yet another preferred embodiment, a tooling system is configured to control the tooling device attached to the crawler frame such that the tooling device is capable of performing construction work.

The tool system is configured to control the tool assembly attached to the crawler frame such that the tool assembly is capable of processing one work area at a time. The tooling system is configured to remotely control the tooling device while processing the construction surface. The tool system can control other devices related to the treatment of the construction surface, such as camera devices and/or sensors etc. The tool system can be in data communication with the surface crawling system.

In yet another advantageous embodiment, the crawler frame comprises a container with a volume in which the tool device is placed in or partially inside.

The container can protect the tool device, which is placed inside or partially inside the crawler frame, from the surrounding environment. The container can also provide a shield to protect the workers during construction work. The container material may include steel, aluminum, or any type of polymeric material. The container can be arranged so that the tool device is able to perform construction work on a structure.

A surface crawling system can be used by attaching a first rope device to a first fixation point and a second rope device to a second rope device relative to a surface so that a crawl zone is provided on

DK 202300052 U3 13 the construction surface. The crawler frame can be arranged relative to a predefined first working position covering a first working area in the crawling zone. The crawler frame can be moved from a first working position to a second working position on the surface, providing a different working area in the crawl zone by varying the distance between the crawler frame and the first and second main fixation points.

A crawler frame is moved along a surface to be treated using the surface crawling system step by step. A first rope device is attached to a first main fixation point and a second rope device to a second main fixation point relative to the structural surface to be treated. Thereby, a crawling zone is defined in relation to the construction surface. The crawler frame is placed in a predefined first working position that covers a first working area in the crawling zone. The working area depends on the size of the frame side facing the construction surface. A workspace for the tool device is related to the area where the tool device is configured to process in the workspace. The crawl zone includes a plurality of work areas. The crawler frame can be placed in a position in relation to the predefined work area. The crawler frame is moved from a first working position at a first working area to a second working position at another working area. The crawler frame is moved from the first working position to the second working position by controlling the rope pulleys and varying the length of the ropes in relation to each other. The control unit controls the movement by lifting, lowering, pushing, pulling and laterally displacing the crawling frame in the crawling zone between the fixation points. The surface-crawling system can be easily and quickly attached to or in relation to a building surface. The rope system is attached to or released from predefined fixation points.

A surface crawling system may move a tool device along a surface using attaching a first auxiliary rope device to a first auxiliary fixation point and a second auxiliary rope device to a second auxiliary fixation point and/or attaching at least a third additional rope device to a third auxiliary fixation point in relation to said construction surface.

A first auxiliary rope device may be attached to the first auxiliary fixation point in relation to or on the construction surface. Another auxiliary rope device may be attached to another auxiliary fixation point in relation to or on the construction surface. This will improve movement in directions other than that of the crawler frame

DK 202300052 U3 14 main directions. Furthermore, at least one third auxiliary rope device can be attached to a third auxiliary fixation point in relation to the construction surface. The third auxiliary fixing point can be placed in a position between the first and the second fixing point in relation to or on the construction surface. Each of the additional rope devices stabilizes the movement and vibration of the crawler frame during displacement and treatment of the surface. The crawler frame can be easily moved from a first working position to another position on the construction surface, and the construction surface in the second work area can then be ready for processing. The crawler frame can be shifted to a third working area by changing the length of the ropes in the rope pulleys in relation to each other.

Treatment of the construction surface may be to remove mortar around each brick using a tool device.
