Description

Technical Field

[0001] This utility model relates to the technical field of high-rise building exterior wall cleaning devices, and in particular to a high-rise building curtain wall cleaning device that can overcome obstacles. Background Technology

[0002] A high-rise curtain wall is a non-load-bearing exterior wall cladding for buildings, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. In practical applications, high-rise curtain walls are exposed to the outdoor environment for extended periods and require regular cleaning to maintain a clean and tidy surface.

[0003] Traditional methods of cleaning high-rise building curtain walls primarily involve manual labor. The process involves attaching a guide rope fixed to the roof of the building to the worker, who is then suspended in mid-air to manually clean the curtain wall surface. This method is not only inefficient but also extremely dangerous, greatly increasing the risk of worker falls and injuries.

[0004] To address the aforementioned technical challenges, some manufacturers have developed high-rise building curtain wall cleaning devices. For example, there is a Chinese invention patent with patent number CN106943091B, titled "Automatic Cleaning Robot for High-Rise Glass Curtain Walls." In this patent, a suspended guide rope pulls a cleaning vehicle along the high-rise curtain wall, enabling it to autonomously complete the cleaning work. However, high-rise curtain walls are often equipped with various types of obstacles at fixed intervals. Relying solely on the wheels for movement means that when the wheels encounter larger obstacles, they cannot pass, resulting in uncleaned areas of the curtain wall.

[0005] Therefore, how to design a high-rise building curtain wall cleaning device with high cleaning efficiency, good cleaning effect and strong obstacle crossing ability is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This invention provides a high-rise building curtain wall cleaning device capable of overcoming obstacles, solving the technical problem of weak obstacle-crossing ability of existing high-rise building curtain wall cleaning devices.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a high-rise building curtain wall cleaning device capable of overcoming obstacles, comprising: a lifting mechanism, a telescopic mechanism, a hoisting mechanism, and a wiping mechanism.

[0008] The lifting mechanism includes a lifting frame, a guide rope, multiple sets of rotating wheels, and a lifting motor. The top end of the guide rope is fixed to the roof of the high-rise building. The multiple sets of rotating wheels rotate at intervals on the lifting frame and each set includes two or more oppositely arranged rotating wheels. Each set of oppositely arranged rotating wheels rotates tightly against the guide rope. The lifting motor is fixed on the lifting frame and drives the multiple sets of rotating wheels to rotate along the guide rope to drive the lifting frame to lift. The fixed part of the telescopic mechanism is fixed on the lifting frame, and its telescopic part reciprocates in the horizontal direction. A suction cup A is fixed on its telescopic part.

[0009] The lifting mechanism includes a folding frame and a lifting push rod. The bottom end of the folding frame is hinged to the telescopic part. The fixed end of the lifting push rod is fixed to the telescopic part, and its lifting end is hinged to the upper end of the folding frame to unfold the folding frame upward or fold the folding frame downward. The wiping mechanism includes a shifting motor and a wiping component. The shifting motor is fixed to the top of the folding frame, and its output shaft is arranged along the height direction. The wiping component is fixed to the output shaft of the shifting motor, and a wiping plate and a suction cup B are fixed on its two sides respectively, so that the positions of the wiping plate and the suction cup B can be changed with the rotation of the output shaft of the shifting motor, so that the suction cup A and the suction cup B can be alternately attached to the curtain wall of the high-rise building to cross the obstacles on the curtain wall.

[0010] The beneficial effects of this utility model are: it optimizes the structure of traditional curtain wall cleaning devices. First, the wiping component is fixed on the output shaft of the shifting motor, and the positions of the suction cup B and the wiping plate are switched. Then, multiple rotating wheels tightly abutting against the guide rope drive the lifting frame to rise and fall. Since the telescopic mechanism is fixed on the lifting frame and the other end of it is fixed with the suction cup A, when the curtain wall cleaning device encounters a large obstacle on the curtain wall of a high-rise building, the suction cup B can be first attached to the curtain wall. After the telescopic mechanism extends and retracts, the suction cup A is detached from the curtain wall, and the rotating wheels are driven to lift the lifting frame, allowing the telescopic mechanism and suction cup A to pass over the obstacle. Then, the suction cup A is attached to the curtain wall, the shifting motor is started, and the positions of the suction cup B and the wiping plate are switched, allowing the wiping plate to clean the curtain wall. Thus, without hindering the wiping plate from cleaning the curtain wall, the curtain wall cleaning device can move over obstacles and thoroughly clean the curtain wall surface.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the lifting frame includes a fixed rod, a first fixed plate, and a second fixed plate. The fixed rod is arranged along the height direction. The first fixed plate is fixed parallel to the middle part of the fixed rod. The second fixed plate is fixed parallel to the lower part of the fixed rod. Multiple sets of rotating wheels rotate at intervals on the first fixed plate. The lifting motor is fixed on the first fixed plate. The fixed part of the telescopic mechanism is fixed on the second fixed plate.

[0013] Furthermore, there are two sets of rotating wheels, two lifting motors, and two guide ropes. The two lifting motors, the two guide ropes, and the two sets of rotating wheels are symmetrically distributed on both sides of the fixed rod and arranged opposite each other.

[0014] The further beneficial effect of adopting the above is that by using two guide ropes symmetrically distributed on both sides of the fixed rod to pass around two sets of multiple rotating wheels, the stability of the lifting frame can be improved.

[0015] Furthermore, the lifting frame also includes a support rod, a guide plate, and guide wheels. The support rod is vertically fixed to the upper part of the fixed rod. There are two guide plates, which are fixed parallel to both ends of the support rod. There are multiple guide wheels, which are divided into two groups. The multiple guide wheels in the two groups rotate at intervals on the two guide plates. Two guide ropes pass over the multiple guide wheels in the two groups respectively.

[0016] Furthermore, the lifting frame also includes multiple slip rings, which are divided into two groups. The multiple slip rings in the two groups are distributed on both sides of the fixed rod and fixed to the second fixed plate at intervals. The two guide ropes slide through the multiple slip rings in the two groups respectively.

[0017] Furthermore, the lifting mechanism also includes a gyroscope, and the gyroscope is fixed between the two sets of rotating wheel groups on the first fixed plate.

[0018] The further beneficial effect of adopting the above is that by using a gyroscope to monitor whether the first fixed plate is horizontal, two lifting motors can be controlled separately, thereby improving the stability of the lifting frame.

[0019] Furthermore, the telescopic mechanism includes a fixed base, a telescopic push rod, multiple telescopic rods, and multiple connecting rods. The multiple telescopic rods are the fixed parts of the telescopic mechanism, and each of the multiple telescopic rods reciprocates horizontally with one end fixed to the lifting frame at intervals. The multiple connecting rods are respectively vertically fixed to adjacent telescopic rods. The fixed base is the fixed part of the telescopic mechanism and is fixed to the other end of the multiple telescopic rods. One end of the telescopic push rod is hinged to the lifting frame, and the other end is hinged to the telescopic rod to push the multiple telescopic rods to reciprocate horizontally. There are multiple suction cups A, which are fixed to the fixed base at intervals. The bottom end of the folding frame is hinged to the fixed base. The fixed end of the lifting push rod is fixed to the fixed base.

[0020] The further beneficial effect of adopting the above is that by using multiple connecting rods that are vertically fixed to multiple telescopic rods, the synchronous extension and retraction of multiple telescopic rods can be achieved by using a telescopic push rod to hinge with a telescopic rod.

[0021] Furthermore, the folding frame includes a first folding arm and a second folding arm, the bottom end of the first folding arm being hinged to the telescopic part; the bottom end of the second folding arm being hinged to the top end of the first folding arm; the lifting push rod includes a first lifting push rod and a second lifting push rod, the fixed end of the first lifting push rod being fixed to the telescopic part and its lifting end being hinged to the first folding arm; the fixed end of the second lifting push rod being fixed to the first folding arm and its lifting end being hinged to the second folding arm; the shifting motor is fixed to the top end of the second folding arm.

[0022] The further beneficial effect of adopting the above is that by hinged the bottom end of the first folding arm to the telescopic mechanism, interference between the first and second folding arms and the obstacle can be prevented when the telescopic mechanism crosses the obstacle.

[0023] Furthermore, the wiping component is a wiping motor, the bottom end of the wiping motor housing is fixed to the top end of the folding frame and its output shaft is arranged in a horizontal direction; the wiping plate is fixed on the output shaft of the wiping motor to rotate the wiping plate to wipe the high-rise building curtain wall; the suction cup B is fixed to the side end of the wiping motor housing.

[0024] The further beneficial effect of adopting the above is that by fixing the wiping plate on the output shaft of the wiping motor arranged in the horizontal direction, the wiping plate can be driven to rotate around the horizontal axis, thereby improving the wiping efficiency and wiping effect of the high-rise building curtain wall.
