Description

Technical Field

[0001] The present invention relates to a quick tool changing mechanism for the end effector of a curtain wall cleaning device and a method of using the same. Background Art

[0002] With the development of modern architecture towards high-rise and curtain wall structures, glass curtain walls, metal curtain walls, and composite exterior wall materials are widely used. High-altitude curtain wall cleaning has become an important part of building operation and maintenance. Traditional manual cleaning relies on the hanging operation of "spidermen", which has extremely high safety risks, low efficiency, and high costs. In recent years, high-altitude cleaning robots and automated equipment have gradually replaced manual work, and the quick tool changing ability of the core functional module - the end effector has become a key technical bottleneck determining the operation efficiency and scene adaptability of the equipment.

[0003] Currently, the tool changing technology for the end effector of high-altitude curtain wall cleaning equipment mainly relies on the following solutions:

[0004] The first is to fix the cleaning tool through manual or simple mechanical structures (such as pins, bolts). Although such a solution has a simple structure, it requires manual intervention after the machine stops, is difficult to operate in high-altitude environments, and the tool changing takes a long time, making it difficult to meet the requirements of continuous operation.

[0005] The second is to use an electromagnet to attract the tool interface. Although such a structure can achieve automatic switching, the electromagnetic device is prone to connection failure due to power failure or signal interference in high-altitude strong wind and vibration environments, and there is a risk of tool detachment.

[0006] The third is to use a linear cylinder to drive a jaw or a thimble to lock the tool. However, its locking force is concentrated on a single point or a linear direction, which is prone to tool deviation due to uneven force, and lacks a self-aligning function, relying on a high-precision positioning system.

[0007] The fourth is to provide a locking force through a hydraulic cylinder. Although it can achieve a high-strength connection, the hydraulic system is large in volume, difficult to maintain, and there is a risk of liquid leakage, making it difficult to meet the requirements of lightweight and high reliability of high-altitude cleaning equipment. Summary of the Invention

[0008] The present invention provides a quick tool changing mechanism for the end effector of a curtain wall cleaning device and a method of using the same to solve the problems existing in the above-mentioned prior art. The present invention solves the problems of low efficiency, poor safety, and insufficient reliability of traditional tool changing technologies in the field of high-altitude cleaning, and provides an efficient, safe, and reliable quick tool changing solution for the end effector of curtain wall cleaning equipment, which is particularly suitable for high-altitude cleaning scenarios with extremely high requirements for operation efficiency and safety.

[0009] The technical solutions adopted by the present invention are as follows:

[0010] A quick-switching mechanism for the end effector of a curtain wall cleaning device, comprising a connector provided on the curtain wall cleaning device and a connecting seat connected to the connector and serving as a mounting carrier for the end effector. The connector is provided with a plurality of locking rods distributed in a spoke-like manner and having locking grooves. All the locking rods can rotate simultaneously in the axial direction thereof and can move simultaneously towards or away from each other; a plurality of lock holes are provided circumferentially on the connecting seat, and a buckle is elastically supported in the lock holes; the connecting seat and the connector are inserted into each other, all the locking rods move away from each other simultaneously and are inserted into the corresponding lock holes, and the locking rods inserted into the lock holes rotate along their axial directions simultaneously, so that the buckle is snapped into the locking groove.

[0011] Further, a driving disc, a linkage pin and a mounting seat are provided inside the connector. The mounting seat is fixed inside the connector, all the locking rods are slidably connected to the mounting seat, the driving disc is rotatably connected to the mounting seat and is driven to rotate by a motor or a rotary cylinder. A plurality of arc grooves distributed in a spoke-like manner are provided circumferentially on the driving disc, each linkage pin passes through the corresponding arc groove and is fixed to a locking rod, and the driving disc rotates to drive all the locking rods to approach or move away from each other simultaneously.

[0012] Further, a plurality of chutes distributed in a spoke-like manner are provided on the mounting seat, and each chute is slidably connected with a locking rod.

[0013] Further, the locking rod comprises a sliding rod portion and a rotating rod portion. The sliding rod portion is slidably connected with the chute, and the rotating rod portion is rotatably connected to the sliding rod portion.

[0014] Further, a straight bevel gear and a gear are provided inside the connector. The straight bevel gear is rotatably connected to the mounting seat and is driven to rotate by a motor or a rotary cylinder. A gear is fixed on the rotating rod portion of each locking rod. All the locking rods move away from each other and drive the gears to move towards the tooth grooves of the straight bevel gear, and the gears are meshed with the straight bevel gear. The straight bevel gear rotates to drive all the locking rods to rotate simultaneously.

[0015] Further, a mounting hole is provided on the hole wall of the lock hole, the buckle is elastically supported in the mounting hole, and a spherical surface is provided on the buckle, and the spherical surface extends into the lock hole.

[0016] Further, the mounting hole is a stepped hole, a T-shaped guide rod and a second spring are arranged in the mounting hole. The T-shaped guide rod is threadedly connected with the buckle, the second spring is sleeved on the T-shaped guide rod, and the upper end of the second spring abuts against the buckle, and the lower end abuts against the stepped surface of the mounting hole.

[0017] Further, the connecting seat comprises an upper seat body and a lower seat body which are fixedly connected to each other. The lock holes and the mounting holes are arranged on the upper seat body, a plurality of blind holes are provided on the lower seat body, the blind holes are communicated with the mounting holes, and the T head of the T-shaped guide rod is placed in the blind holes.

[0018] Furthermore, a positioning boss is provided on the bottom surface of the connector head, and a positioning hole adapted to the positioning boss is provided on the connector seat.

[0019] The present invention also discloses a method for using the above switching mechanism.

[0020] After the connector seat is sleeved on the connector head, the driving disk is rotated, and all the locking rods are moved away from each other and inserted into the lock holes on the connector seat. During the process of the locking rods being inserted into the lock holes, the buckle is pressed into the mounting hole. After the locking rods extend to the required position, the straight bevel gear is rotated to drive all the locking rods to rotate simultaneously. After the locking grooves on the locking rods are aligned with the buckle, the buckle pops out and is snapped into the locking groove to complete the assembly of the connector seat and the connector head.

[0021] When replacing or disassembling the connector seat, the straight bevel gear is rotated in the reverse direction to disengage the locking groove from the buckle, then the driving disk is rotated in the reverse direction, and all the locking rods are moved closer to each other and disengaged from the lock holes, and then the connector seat is removed.

[0022] The present invention has the following beneficial effects:

[0023] 1) Through the synchronous backward or forward movement of the locking rods, the present invention realizes the rapid assembly and disassembly of the end effector, greatly shortening the tool switching time. Driven by a motor or a rotary cylinder, no manual intervention is required, especially suitable for high-altitude operation scenarios, and improving the operation efficiency. When assembling the connector head and the connector seat, they are assembled first and then locked. When disassembling, they are unlocked first and then separated, avoiding accidental detachment of the tool during the switching process and ensuring the safety of high-altitude operations. Through the cooperation of the buckle and the locking groove, reliable mechanical locking is provided to prevent the tool from loosening due to vibration or external force.

[0024] 2) The locking rods are distributed in a spoke shape, evenly applying the locking force, avoiding tool offset or uneven force. Through the cooperation of the positioning boss and the positioning hole, the rapid alignment of the connector seat and the connector head is ensured, simplifying the operation process, not relying on an electromagnet or a hydraulic system, and avoiding connection failure caused by signal interference or liquid leakage.

[0025] 3) The connector seat can be used as an installation carrier for the end effector, supporting the rapid adaptation of a variety of cleaning tools (such as cleaning brushes, cleaning scrapers, etc.), expanding the application scenarios, and the overall design is simple, meeting the lightweight requirements of high-altitude cleaning equipment.

[0026] 4) The connector seat adopts an upper and lower split design, facilitating the installation and maintenance of components such as buckles and springs. The rotation of the locking rods is realized through mechanical transmission (such as the linkage of a straight bevel gear and a gear), avoiding the maintenance problems of complex electronic components.

[0027] 5) Through the cooperation of the steel balls and the tooth grooves, the rotation of the locking rods due to vibration before being inserted into the lock holes is prevented, ensuring the precise alignment of the locking grooves and the buckles. Description of the Drawings

[0051] The present invention will be further described below with reference to the accompanying drawings.

[0052] As Figures 1 to 3 , a quick-switching mechanism for the end effector of a curtain wall cleaning device of the present invention includes a connecting head 1 and a connecting seat 2. The connecting head 1 is arranged on the curtain wall cleaning device. The connecting seat 2 is a replaceable structure and is a mounting carrier for the end effector (the end effector is: a cleaning scraper, a cleaning brush, etc.). When the connecting head 1 and the connecting seat 2 are assembled, the mode of "assemble first and then lock" is adopted. Correspondingly, when disassembling, the mode of "unlock first and then separate" is adopted, thus avoiding the risk of accidental detachment of the tool (i.e., the end effector). The assembly structure of the connecting head 1 and the connecting seat 2 will be described in detail below.

[0053] On the connecting head 1, there are a number of locking rods 11 distributed in a spoke shape (i.e., distributed along the circumferential direction of the connecting head 1). At the end of each locking rod 11, there is a locking groove 110. All the locking rods 11 can rotate simultaneously along their axial directions and can also move simultaneously towards or away from each other.

[0054] Combined with Figure 4 , on the circumferential direction of the outer wall of the connecting seat 2, there are a number of lock holes 21. The lock holes 21 are through holes, and the axes are perpendicular to the axis of the connecting seat 2. Inside the lock holes 21, there is an elastic support for a buckle 22.

[0055] The connecting seat 2 and the connecting head 1 are inserted into each other. All the locking rods 11 move away from each other simultaneously and are inserted into the corresponding lock holes 21 (assemble first). The locking rods 11 inserted into the lock holes 21 rotate along their axial directions simultaneously, so that the buckle 22 is snapped into the locking groove 110 (lock later).

[0056] As Figures 5 to 9 , inside the connecting head 1, there are a driving disk 31, a linking pin 32 and a mounting seat 33. The mounting seat 33 is fixed inside the connecting head 1. All the locking rods 11 are evenly distributed along the circumference of the mounting seat 33, and each locking rod 11 is slidably connected to the mounting seat 33. The driving disk 31 is arranged above the mounting seat 33 and is rotatably connected to the mounting seat 33. The driving disk 31 is driven to rotate by a motor or a rotary cylinder (in this embodiment, the driving by a rotary cylinder is taken as an example).

[0057] A number of arc grooves 310 that are radially dispersed in a spoke shape are provided in the circumferential direction of the drive disk 31. Each linkage pin 32 correspondingly passes through an arc groove 310 and is fixed to a locking rod 11. The rotary cylinder drives the drive disk 31 to rotate. With the cooperation of the arc groove 310 and the linkage pin 32, all the locking rods 11 approach or move away from each other simultaneously.

[0058] To enable the locking rod 11 to be slidably connected to the mounting seat 33, a number of connecting arms that are radially dispersed in a spoke shape are provided on the mounting seat 33. A chute 331 is provided on each connecting arm, and a locking rod 11 is slidably connected in each chute.

[0059] Since the locking rod 11 needs to rotate in its own axial direction and the locking rod 11 is slidably connected in the chute 331, in order to simultaneously meet the linear sliding and self-rotation of the locking rod 11, the present invention specially designs the structure of the locking rod 11 to achieve a "compound" motion. This structure mainly makes the locking rod 11 into two components, that is, including a sliding rod portion 111 and a rotating rod portion 112. The sliding rod portion 111 is slidably connected to the chute 331, and the rotating rod portion 112 is rotatably connected to the sliding rod portion 111 through a bearing.

[0060] Combined Figure 10 , and because the rotating rod portion 112 only needs to rotate when "locking" and "unlocking", and the rotating rod portion 112 is rotatably connected to the sliding rod portion 111 through a bearing, before inserting into the lock hole 21, the rotating rod portion 112 may "rotate on its own" due to vibration, resulting in the locking grooves 110 on each rotating rod portion 112 not being at the same angle, thus affecting the subsequent "locking" process. To avoid this phenomenon, that is, the rotating rod portion 112 does not need to rotate on its own, a toothed groove is provided on the outer circumferential direction of the outer wall of the sliding rod portion 111. A through hole is provided in the radial direction of the rotating rod portion 112. A first spring 113, a steel ball 114, and a setscrew 115 are provided in the through hole. The setscrew 115 is threadedly connected to the through hole and one end is placed outside the through hole. One end of the steel ball 114 extends out of the through hole and abuts against the toothed groove on the sliding rod portion 111. One end of the first spring 113 abuts against the setscrew 115, and the other end abuts against the steel ball 114. Adjusting the setscrew 115 can adjust the compression amount of the first spring 113.

[0061] Since the steel ball 114 abuts against the toothed groove on the sliding rod portion 111, the "self-rotation" phenomenon of the rotating rod portion 112 due to external vibrations and other factors can be effectively avoided. Only when an axial driving force is applied to the rotating rod portion 112, the rotating rod portion 112 will rotate (a clicking sound will be emitted during the rotation process).

[0062] The driving structure for applying an axial driving force is further described below.

[0063] A spur bevel gear 41 and a gear 42 are provided in the connector 1. The spur bevel gear 41 is provided below the mounting seat 33. The spur bevel gear 41 is rotatably connected to the mounting seat 33 and is driven to rotate by a motor or a rotary cylinder (in this embodiment, the rotary cylinder is used as an example). A gear 42 is fixed to the rotating rod portion 112 of each locking rod 11. All locking rods 11 move away from each other and drive the gear 42 to move toward the tooth groove direction of the spur bevel gear 41, and the gear 42 is meshed with the spur bevel gear 41. The rotary cylinder drives the spur bevel gear 41 to rotate and drives all locking rods 11 to rotate at the same time.

[0064] like Figure 11 The buckle 22 mounting structure of the present invention is as follows: a mounting hole 211 is provided on the hole wall of the lock hole 21, the buckle 22 is elastically supported in the mounting hole 211, and a spherical surface is provided on the buckle 22, and the spherical surface extends into the lock hole 21. When the rotating rod 112 is inserted into the lock hole 21, the buckle 22 is pressed into the mounting hole 211, and the spherical structure of the buckle 22 makes it easier for the rotating rod 112 to act on the buckle 22.

[0065] In order to elastically support the buckle 22 in the lock hole 21, a T-shaped guide rod 25 and a second spring 26 are provided in the mounting hole 211. The T-shaped guide rod 25 is threadedly connected to the buckle 22. The second spring 26 is sleeved on the T-shaped guide rod 25, and the upper end of the second spring 26 abuts against the buckle 22, and the lower end abuts against the step surface of the mounting hole 211. The buckle 22 is axially limited in the mounting hole 211 by the T-shaped guide rod 25.

[0066] In order to facilitate the installation of the buckle 22, the connecting seat 2 adopts a split structure, which includes an upper seat body 23 and a lower seat body 24 fixed to each other, the lock hole 21 and the mounting hole 211 are both provided on the upper seat body 23, and a plurality of blind holes 241 are provided on the lower seat body 24, each blind hole 241 corresponding to a mounting hole 211 is passed through, after the T-shaped guide rod 25, the second spring 26 and the buckle 22 are assembled in the mounting hole 211, the upper seat body 23 and the lower seat body 24 are fixed, and at this time, the T head of the T-shaped guide rod 25 is just placed in the blind hole 241. Through the limitation of the T head, the buckle 22 will not be separated from the lock hole 21 and can be pressed.

[0067] like Figure 12 When the connector 1 is assembled with the connector base 2, since each locking rod 11 must be coaxial with each locking hole, in order to quickly ensure that the connector base 2 is in an accurate assembly position, three positioning bosses 12 are provided on the bottom surface of the connector 1, and three positioning holes 27 adapted to the positioning bosses 12 are provided on the connector base 2. Through the positioning of the positioning bosses 12 and the positioning holes 27, the connector base 2 and the connector 1 are quickly positioned.

[0068] The following further describes the method of using the present invention.

[0069] After the connecting seat 2 is sleeved on the connecting head 1, at this time, each locking rod 11 is coaxial with each lock hole. There are two buttons provided on the connecting head 1 or the curtain wall cleaning device, corresponding to controlling two rotary cylinders. By controlling the rotation of the driving disc 31, all the locking rods 11 are moved away from each other, and the rotating rod portion 112 is inserted into the lock hole 21 on the connecting seat 2. During the process of the rotating rod portion 112 being inserted into the lock hole 21, the buckle 22 is pressed into the mounting hole 211. After the rotating rod portion 112 extends to the required position, the driving straight bevel gear 41 is rotated. Through the linkage of the straight bevel gear 41 and the gear 42, all the rotating rod portions 112 are driven to rotate simultaneously. After the locking groove 110 on the rotating rod portion 112 is aligned with the buckle 22, the buckle 22 pops out and is snapped into the locking groove 110, completing the assembly of the connecting seat 2 and the connecting head 1.

[0070] When replacing or disassembling the connecting seat 2, the driving straight bevel gear 41 rotates in the reverse direction to disengage the locking groove 110 from the buckle 22, then the driving disc 31 is driven to reverse, and all the locking rods 11 are moved closer to each other and disengaged from the lock hole 21, and then the connecting seat 2 can be removed.

[0071] The present invention can quickly switch the end effector and the tool adaptor, realizing the efficient, safe switching and reliable connection of the cleaning tool in the high-altitude operation scenario. Its uniquely designed locking rods that move synchronously towards or away from each other have good linkage. When assembling the connecting seat and the connecting head, the locking rods move away from each other simultaneously and are inserted into the corresponding lock holes 21 (first assembly). The locking rods inserted into the lock holes rotate along their axial directions simultaneously, causing the buckle to be snapped into the locking groove (then locked). This not only avoids the risk of accidental detachment of the tool but also simplifies the operation process. The connecting seat can be modularly designed, enabling the device to be adapted to a variety of cleaning tools, expanding the adaptability of the application scenario, and is especially suitable for the strict requirements of rapid tool change and operation safety in the field of high-altitude curtain wall cleaning.

[0072] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
