Description

Technical Field

[0001] This application relates to the field of curtain wall maintenance equipment, and in particular to a curtain wall adsorption device based on a parallelogram structure. Background Technology

[0002] Glass curtain walls occupy an important position in the facades of modern buildings, significantly enhancing their aesthetics and playing a vital role in energy conservation and sound insulation. However, as glass curtain walls age, their waterproofing and structural strength decrease, necessitating regular inspection and maintenance.

[0003] Existing glass curtain wall maintenance can be carried out using curtain wall adsorption equipment. The curtain wall adsorption equipment includes a main body, multiple electric push rods, and multiple adsorption mechanisms. The main body includes two base plates that are rotatably connected. A motor is installed between the base plates. One end of the electric push rod is connected to the main body, and the other end is connected to the adsorption mechanism. The adsorption mechanism is used to adsorb onto the curtain wall. An electric slide rail is installed between the electric push rod and the main body. The electric slide rail is used to drive the electric push rod and the adsorption mechanism to move in a straight line relative to the main body. By having the adsorption mechanism alternately adsorb onto the curtain wall, the curtain wall adsorption equipment can move and turn in a straight line on the curtain wall.

[0004] The aforementioned technical solutions have the following drawbacks: the movement of the curtain wall adsorption equipment requires the coordinated action of multiple driving components, necessitates the installation of numerous power components, and results in significant energy consumption. Utility Model Content

[0005] In order to reduce the number of driving components in the curtain wall adsorption device, this application provides a curtain wall adsorption device based on a parallelogram structure.

[0006] The curtain wall adsorption device based on a parallelogram structure provided in this application adopts the following technical solution:

[0007] A curtain wall adsorption device based on a parallelogram structure includes a parallelogram frame, electric push rods, a drive mechanism, a drive rod, and an adsorption mechanism. The parallelogram frame includes four connecting rods, with the ends of the connecting rods rotatably connected to the ends of other connecting rods. The four connecting rods are assembled to form a parallelogram frame structure. Four electric push rods are provided, each located at a vertex of the parallelogram frame. Each electric push rod has an adsorption mechanism at its end, which is used to adsorb onto the curtain wall. The two ends of the drive rod are rotatably connected to two opposite connecting rods, and the drive mechanism is used to control the rotation of the drive rod on the connecting rod.

[0008] By adopting the above technical solution, a parallelogram frame is assembled using connecting rods. A drive rod is set in the middle of the parallelogram frame, causing the drive mechanism to rotate relative to the connecting rod on which the drive rod is located. This causes the drive rod to deform the parallelogram frame, changing the position of the electric push rod and the adsorption mechanism at the vertices of the parallelogram. When the curtain wall adsorption device is installed on the curtain wall, by having two adjacent adsorption mechanisms adhere to the curtain wall while the other two adsorption mechanisms are disconnected from the curtain wall, the parallelogram frame deforms, changing the position of the two adsorption mechanisms disconnected from the curtain wall. By having multiple adsorption mechanisms alternately adsorb onto the curtain wall, the curtain wall adsorption device can move and turn on the curtain wall. The drive mechanism, by controlling the rotation of the drive components, can drive the curtain wall adsorption device to move and turn in a straight line, making it more convenient to control the turning of the curtain wall adsorption device.

[0009] Optionally, the multiple links may have the same length.

[0010] By adopting the above technical solution and setting the connecting rods to be rods of the same length, the calculation of the moving path of the adsorption mechanism at the four vertices when the parallelogram frame deforms is made simpler. When the driving rod drives the parallelogram frame to deform, the force on the driving rod is smaller, and the power required for the deformation of the parallelogram frame is smaller.

[0011] Optionally, the length of the drive rod is the same as the length of the connecting rod.

[0012] By adopting the above technical solution, and by setting the length of the drive rod to be the same as that of the connecting rod, the drive rod is parallel to the connecting rods on both sides. When the drive rod rotates, the stress at both ends is similar, the stress concentration on the drive rod is small, and the service life is improved.

[0013] Optionally, the drive rod is connected at the center of the connecting rod.

[0014] By adopting the above technical solution, and by connecting the drive rod to the center of the connecting rod, when the drive rod rotates, the drive rod applies a pulling force to the center of the connecting rod, so that the stress on the connecting rod is uniform and the parallelogram frame structure has better strength.

[0015] Optionally, the electric actuator is perpendicular to the parallelogram frame.

[0016] By adopting the above technical solution, and by setting the electric push rod to be perpendicular to the parallelogram frame, when the adsorption mechanism on the electric push rod is adsorbed onto the curtain wall, the parallelogram frame is parallel to the curtain wall, and the sensor on the parallelogram frame collects data with high positional accuracy.

[0017] Optionally, the drive mechanism is configured as a motor.

[0018] By adopting the above technical solution, and by setting the drive mechanism as a motor, the motor can drive the drive rod to rotate forward and backward on the connecting rod. The user can control the rotation amplitude of the drive rod through the motor, and the movement amplitude of the curtain wall adsorption device is controlled with high precision.

[0019] Optionally, the adsorption mechanism includes a support leg and a vacuum suction cup. The vacuum suction cup is made of an elastic material and is fixed to the end of the electric push rod. The support leg includes a connecting ring, a cover ring, and multiple connectors. The connecting ring is sleeved on the electric push rod, the cover ring is sleeved outside the vacuum suction cup, and the multiple connectors are equidistantly spaced along the circumference of the connecting ring. One end of the connector is fixed to the connecting ring, and the other end is fixed to the connector.

[0020] By adopting the above technical solution, a vacuum suction cup is set at the end of the electric push rod, which allows the vacuum suction cup to abut against the curtain wall. The vacuum suction cup can deform and adhere to the curtain wall, allowing the curtain wall adsorption device to adhere to the curtain wall. By setting support legs outside the vacuum suction cup, the support legs cover the vacuum suction cup, which protects the vacuum suction cup and reduces the probability of debris hitting or adsorbing onto the surface of the vacuum suction cup.

[0021] Optionally, the support leg is made of an elastic material.

[0022] By adopting the above technical solution, the support legs are made of elastic materials, allowing them to be completely fitted over the vacuum suction cup. When the electric push rod controls the suction mechanism to abut against the curtain wall, the support legs first abut against the curtain wall. As the electric push rod continues to extend, the support legs deform and the vacuum suction cup extends out from the support legs, allowing the vacuum suction cup to adhere to the curtain wall, further enhancing the protective effect of the support legs on the vacuum suction cup.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By using connecting rods to form a parallelogram frame, and setting a drive rod in the middle of the parallelogram frame, the drive mechanism drives the drive rod to rotate relative to the connecting rod on which the drive rod is located. This causes the drive rod to deform the parallelogram frame, changing the position of the electric push rod and the adsorption mechanism at the vertices of the parallelogram. When the curtain wall adsorption device is installed on the curtain wall, by having two adjacent adsorption mechanisms adhere to the curtain wall and the other two adsorption mechanisms disengage from the curtain wall, the parallelogram frame deforms, changing the position of the two adsorption mechanisms that are disengaged from the curtain wall. By having multiple adsorption mechanisms alternately adsorb onto the curtain wall, the curtain wall adsorption device can move and turn on the curtain wall. The drive mechanism, by controlling the rotation of the drive components, can drive the curtain wall adsorption device to move and turn in a straight line, making it more convenient to control the turning of the curtain wall adsorption device.

[0025] 2. By connecting the drive rod to the center of the connecting rod, when the drive rod rotates, the drive rod applies a tensile force to the center of the connecting rod, making the stress on the connecting rod uniform and the parallelogram frame structure has better strength.

[0026] 3. By setting a vacuum suction cup at the end of the electric push rod, the vacuum suction cup can be pressed against the curtain wall by the electric push rod. The vacuum suction cup can deform and fit against the curtain wall, so that the curtain wall adsorption device can be adsorbed on the curtain wall. By setting a support leg outside the vacuum suction cup, the support leg covers the vacuum suction cup, which can protect the vacuum suction cup and reduce the probability of debris hitting or adsorbing onto the surface of the vacuum suction cup.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a curtain wall adsorption device based on a parallelogram structure, referring to... Figure 1 , Figure 2 and Figure 3The system includes a parallelogram frame 1, multiple electric push rods 2, a drive mechanism 3, a drive rod 4, and multiple adsorption mechanisms 5. The parallelogram frame 1 includes four connecting rods 11 of equal length, with the ends of the connecting rods 11 rotatably connected to the ends of other connecting rods 11. The four connecting rods 11 form a parallelogram frame structure. Four electric push rods 2 are respectively located at the vertices of the parallelogram frame 1. The main body of each electric push rod 2 is fixed to one connecting rod 11, and the push rod of each electric push rod 2 passes through two connecting rods 11 and is rotatably connected to them. Each push rod 2 has an adsorption mechanism 5 connected to its end. Multiple adsorption mechanisms 5 are located on one side of the parallelogram frame 1 and are used for adsorption. On the curtain wall surface, the two ends of the drive rod 4 are rotatably connected to two opposite connecting rods 11. The drive mechanism 3 is used to drive the drive rod 4 to rotate relative to the connecting rods 11. When the drive rod 4 rotates relative to the connecting rods 11, the shape of the parallelogram frame 1 changes, thereby changing the position of the adsorption mechanism 5 at the end of the parallelogram. When the curtain wall adsorption device needs to move on the curtain wall, two adjacent adsorption mechanisms 5 on the curtain wall adsorption device are connected to the curtain wall, and the other two adsorption mechanisms 5 are disconnected from the curtain wall. At this time, the shape of the parallelogram frame 1 changes, which can drive the position of the two adsorption mechanisms 5 that are disconnected from the curtain wall. By controlling the adsorption mechanisms 5 to alternately connect and disconnect from the curtain wall, the curtain wall adsorption device can move in different directions on the curtain wall.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The electric push rod 2 is perpendicular to the parallelogram frame 1 in its length direction. The electric push rod 2 can drive the adsorption mechanism 5 to move closer to or away from the parallelogram frame 1, thereby enabling the adsorption mechanism 5 to abut against and adsorb onto the curtain wall. When there are stepped obstacles on the curtain wall, by controlling the distance between the multiple adsorption mechanisms 5 and the parallelogram frame 1, the curtain wall adsorption device can move on the irregular surface of the curtain wall.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The drive mechanism 3 is a motor, the motor housing of which is fixed to the connecting rod 11. The output shaft of the motor passes through the connecting rod 11 and is coaxially connected to the end of the drive rod 4. The motor drives the drive rod 4 to rotate on the connecting rod 11. The length direction of the drive rod 4 is parallel to the connecting rods 11 on both sides of the drive rod 4. The motor controls the shape of the parallelogram frame 1 by adjusting the angle between the drive rod 4 and the connecting rod 11 connected to the drive rod 4. The drive rod 4 is rotatably connected to the center of the connecting rod 11. When the motor drives the drive rod 4 to rotate in both directions, the parallelogram frame 1 experiences the same force, thus enabling the motor to drive the parallelogram frame 1 to deform with a smaller torque.

[0036] Reference Figure 4 The adsorption mechanism 5 includes a support leg 51 and a vacuum suction cup 52. The support leg 51 is connected to the electric push rod 2, and the vacuum suction cup 52 is connected to the end of the electric push rod 2. The vacuum suction cup 52 is made of elastic rubber material. When the electric push rod 2 presses the vacuum suction cup 52 against the curtain wall, the vacuum suction cup 52 deforms and adsorbs onto the curtain wall.

[0037] Reference Figure 4 The support leg 51 includes a connecting ring 511, a cover ring 512, and multiple connectors 513. The connecting ring 511 is sleeved on the electric push rod 2, and the cover ring 512 is coaxially sleeved on the outside of the vacuum suction cup 52. The multiple connectors 513 are equidistantly arranged along the circumference of the connecting ring 511, with one end of each connector 513 fixed to the connecting ring 511 and the other end fixed to the cover ring 512. The support leg 51 protects the vacuum suction cup 52, reducing the probability of debris impacting or adhering to the vacuum suction cup 52, thereby enabling the adsorption mechanism 5 to be stably attached to the curtain wall. In other embodiments, the support leg 51 is made of an elastic material and can be fitted over the vacuum suction cup 52. When the electric push rod 2 extends and abuts the suction mechanism 5 against the curtain wall, the support leg 51 first contacts the curtain wall. As the electric push rod 2 continues to extend, the support leg 51 deforms and the vacuum suction cup 52 abuts against the curtain wall. The support leg 51 is fitted over the vacuum suction cup 52, which further reduces the chance of debris adhering to the surface of the vacuum suction cup 52 and causing the suction capacity of the vacuum suction cup 52 to decrease.

[0038] The implementation principle of this application embodiment is as follows: by setting four electric push rods 2 at the vertices of the parallelogram frame 1, each electric push rod 2 can drive an adsorption mechanism 5 to move. By making the adsorption mechanism 5 abut against the curtain wall, the curtain wall adsorption device can be fixed on the curtain wall. When the curtain wall adsorption device moves, two adjacent adsorption mechanisms 5 are disengaged from the curtain wall. The driving mechanism 3 drives the driving rod 4 to rotate, thereby changing the shape of the parallelogram frame 1. At this time, the positions of the two adsorption mechanisms 5 that are disengaged from the curtain wall move. By making multiple adsorption mechanisms 5 move alternately, the curtain wall adsorption device can move in different directions.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
