Description

Technical Field

[0001] The invention relates to a quick switching mechanism for an end actuator of curtain wall cleaning equipment and a use method thereof. Background Art

[0002] As modern buildings develop towards high-rises and curtain walls, glass curtain walls, metal curtain walls and composite exterior wall materials are widely used, and high-altitude curtain wall cleaning has become an important part of building operation and maintenance. Traditional manual cleaning relies on Spider-Man's hanging operation, 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 operations, and their core functional module - the ability to quickly switch tools of the end effector has become a key technical bottleneck that determines the equipment's operating efficiency and scene adaptability.

[0003] At present, the end-effector tool switching technology of high-altitude curtain wall cleaning equipment mainly relies on the following solutions: The first is to fix the cleaning tool manually or with a simple mechanical structure (such as a latch or bolt). Although this solution is simple in structure, it requires manual intervention after the machine is shut down, is difficult to operate in a high-altitude environment, and takes a long time to switch tools, making it difficult to meet the needs of continuous operation.

[0004] The second method is to use an electromagnet to attract the tool interface. Although this structure can achieve automatic switching, the electromagnetic device is prone to connection failure due to power outages or signal interference in high-altitude strong winds and vibration environments, and there is a risk of the tool falling off.

[0005] The third type uses a linear cylinder to drive the clamp or ejector to lock the tool, but its locking force is concentrated on a single point or linear direction, which can easily cause tool displacement due to uneven force, and lacks self-alignment function, requiring reliance on a high-precision positioning system.

[0006] The fourth method is to provide locking force through a hydraulic cylinder. Although it can achieve high-strength connection, the hydraulic system is bulky, difficult to maintain, and has the risk of leakage. It is difficult to adapt to the lightweight and high reliability requirements of high-altitude cleaning equipment. Summary of the invention

[0007] The present invention is to solve the problems existing in the above-mentioned prior art and provide a quick switching mechanism and method for the end effector of curtain wall cleaning equipment. The present invention solves the problems of low efficiency, poor safety and insufficient reliability of traditional tool switching technology in the field of high-altitude cleaning, and provides an efficient, safe and reliable solution for quick switching of end effectors for curtain wall cleaning equipment, which is particularly suitable for high-altitude cleaning scenes with extremely high requirements for operating efficiency and safety.

[0008] The technical solutions adopted in the present invention are: A quick switching mechanism for an end effector of a curtain wall cleaning device comprises a connecting head arranged on the curtain wall cleaning device, and a connecting seat connected to the connecting head and serving as a mounting carrier for the end effector, wherein the connecting head is provided with a plurality of locking rods with locking grooves distributed in a spoke shape, and all the locking rods can simultaneously rotate along their axial directions, and can simultaneously move towards each other or away from each other; a plurality of locking holes are circumferentially arranged on the connecting seat, and buckles are elastically supported in the locking holes; the connecting seat and the connecting head are plugged into each other, and all the locking rods simultaneously move away from each other and are inserted into corresponding locking holes, and the locking rods inserted into the locking holes simultaneously rotate along their axial directions, so that the buckles are snapped into the locking grooves.

[0009] Furthermore, a driving disk, a linkage pin and a mounting seat are provided in the connecting head, the mounting seat is fixed in the connecting head, all the locking rods are slidably connected to the mounting seat, the driving disk is rotatably connected to the mounting seat, and is driven to rotate by a motor or a rotary cylinder. A plurality of arc grooves spread out in a spoke shape are provided in the circumference of the driving disk, each linkage pin passes through the corresponding arc groove and is fixed to a locking rod, the driving disk rotates and drives all the locking rods to approach or move away from each other at the same time.

[0010] Furthermore, a plurality of sliding grooves spread out in a spoke shape are arranged on the mounting seat, and a locking rod is slidably connected in each sliding groove.

[0011] Furthermore, the locking rod includes a sliding rod portion and a rotating rod portion, the sliding rod portion is slidably connected to the sliding groove, and the rotating rod portion is rotatably connected to the sliding rod portion.

[0012] Furthermore, a spur bevel gear and a gear are provided in the connecting head. The spur 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 locking rods move away from each other and drive the gear to move in the direction of the tooth groove of the spur bevel gear, and the gear is meshed with the spur bevel gear. The spur bevel gear rotates and drives all locking rods to rotate simultaneously.

[0013] Furthermore, 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.

[0014] Furthermore, the mounting hole is a stepped hole, in which a T-shaped guide rod and a second spring are arranged, the T-shaped guide rod is threadedly connected to 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.

[0015] Furthermore, the connecting seat includes an upper seat body and a lower seat body fixed to each other, a locking hole and a mounting hole are arranged on the upper seat body, and a plurality of blind holes are arranged on the lower seat body, the blind holes are connected with the mounting holes, and the T heads of the T-shaped guide rods are placed in the blind holes.

[0016] Furthermore, a positioning boss is provided on the bottom surface of the connector, and a positioning hole matched with the positioning boss is provided on the connector seat.

[0017] The present invention also discloses a method for using the switching mechanism. After the connecting seat is sleeved on the connecting head, the driving disk is driven to rotate, and all the locking rods are moved away from each other and inserted into the locking holes on the connecting seat. During the process of inserting the locking rods into the locking holes, the buckles are pressed into the mounting holes. After the locking rods are extended to the required positions, the spur bevel gears are driven to rotate and drive all the locking rods to rotate at the same time. After the locking grooves on the locking rods are aligned with the buckles, the buckles pop out and snap into the locking grooves, completing the assembly of the connecting seat and the connecting head. When replacing or removing the connecting seat, the spur bevel gear is driven to rotate in the opposite direction to disengage the locking groove from the buckle, and then the driving disc is driven to reverse and all the locking rods are brought close to each other and disengaged from the locking hole, and then the connecting seat is removed.

[0018] The present invention has the following beneficial effects: 1) The present invention realizes the rapid assembly and disassembly of the end effector through the synchronous back-to-back or opposite movement of the locking rod, greatly shortening the tool switching time. It is driven by a motor or a rotary cylinder and does not require manual intervention. It is particularly suitable for high-altitude operation scenarios and improves work efficiency. When assembling the connector and the connector seat, they are assembled first and then locked. When disassembling, they are unlocked first and then separated to prevent the tool from accidentally falling off during the switching process and ensure the safety of high-altitude operations. The cooperation between the buckle and the locking groove provides reliable mechanical locking to prevent the tool from loosening due to vibration or external force.

[0019] 2) The locking rods are distributed in a spoke shape to evenly apply locking force to avoid tool deviation or uneven force. The positioning boss and the positioning hole cooperate to ensure quick alignment of the connector and the connector, simplifying the operation process. It does not rely on electromagnets or hydraulic systems, and avoids connection failure caused by signal interference or leakage.

[0020] 3) The connecting seat can be used as an installation carrier for the end effector, supporting the rapid adaptation of various cleaning tools (such as cleaning brushes, cleaning scrapers, etc.), expanding the application scenarios, and the overall design is simple, which is suitable for the lightweight requirements of high-altitude cleaning equipment.

[0021] 4) The connection seat adopts an upper and lower split design, which is convenient for the installation and maintenance of components such as buckles and springs. The locking rod is rotated through mechanical transmission (such as spur bevel gears and gear linkage) to avoid the maintenance difficulties of complex electronic components.

[0022] 5) The cooperation between the steel ball and the tooth groove prevents the locking rod from rotating due to vibration before being inserted into the lock hole, ensuring the precise alignment of the locking groove and the buckle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] like Figures 1 to 3 The present invention discloses a quick switching mechanism for an end effector of a curtain wall cleaning device, comprising a connector 1 and a connector seat 2. The connector 1 is arranged on the curtain wall cleaning device, and the connector seat 2 is a replaceable structure, which is a mounting carrier for the end effector (the end effector is a cleaning scraper, a cleaning brush, etc.). The connector 1 and the connector seat 2 are assembled in a "first assemble and then lock" mode, and correspondingly, the "first unlock and then separate" mode is adopted during disassembly, thereby avoiding the risk of accidental falling off of the tool (i.e., the end effector). The assembly structure of the connector 1 and the connector seat 2 is described in detail below.

[0038] A plurality of locking rods 11 are arranged on the connector 1 in a spoke-like arrangement (i.e., arranged along the circumference of the connector 1), and a locking groove 110 is arranged at the end of each locking rod 11. All locking rods 11 can simultaneously rotate along their axial directions, and can simultaneously move toward or away from each other.

[0039] Combination Figure 4 A plurality of locking holes 21 are provided in the circumferential direction of the outer wall of the connecting seat 2 . The locking holes 21 are through holes, and the axes thereof are perpendicular to the axis of the connecting seat 2 . A buckle 22 is elastically supported in the locking holes 21 .

[0040] The connecting seat 2 and the connecting head 1 are plugged into each other, and all the locking rods 11 move backwards at the same time and are inserted into the corresponding locking holes 21 (assemble first). The locking rods 11 inserted into the locking holes 21 are rotated along their axial direction at the same time, so that the buckle 22 is locked into the locking groove 110 (later locked).

[0041] like Figures 5 to 9 A driving disk 31, a linkage pin 32 and a mounting seat 33 are provided in the connector 1. The mounting seat 33 is fixed in the connector 1. All 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 the driving disk 31 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 rotary cylinder drive is used as an example).

[0042] A plurality of spoke-shaped arc grooves 310 are provided in the circumference of the driving disk 31. Each linkage pin 32 passes through a corresponding arc groove 310 and is fixed to a locking rod 11. The rotary cylinder drives the driving disk 31 to rotate. With the cooperation of the arc grooves 310 and the linkage pins 32, all the locking rods 11 approach or move away from each other at the same time.

[0043] In order to make the locking rod 11 slidably connected to the mounting seat 33 , a plurality of connecting arms spread out in a spoke shape are provided on the mounting seat 33 , each connecting arm is provided with a sliding groove 331 , and a locking rod 11 is slidably connected in each sliding groove.

[0044] Since the locking rod 11 needs to rotate in its own axial direction, and the locking rod 11 is slidably connected in the slide groove 331, in order to simultaneously satisfy the linear sliding of the locking rod 11 and its own rotation, the present invention specially designs the structure of the locking rod 11 to achieve "compound" movement. The structure mainly makes the locking rod 11 into two parts, namely, a sliding rod part 111 and a rotating rod part 112, wherein the sliding rod part 111 is slidably connected to the slide groove 331, and the rotating rod part 112 is rotatably connected to the sliding rod part 111 through a bearing.

[0045] Combination Fig.10 , and because the rotating rod portion 112 needs to rotate only when "locking" and "unlocking", and the rotating rod portion 112 is rotatably connected to the sliding rod portion 111 through a bearing, before being inserted into the lock hole 21, the rotating rod portion 112 may "rotate" due to vibration, causing the locking grooves 110 on each rotating rod portion 112 to be at different angles, thereby affecting the subsequent "locking" process. In order to avoid the occurrence of this phenomenon, that is, there is no need for the rotating rod part 112 to rotate, a tooth groove is provided in the circumferential direction of the outer wall of the sliding rod part 111, and a through hole is provided in the radial direction of the rotating rod part 112. A first spring 113, a steel ball 114 and a top screw 115 are provided in the through hole. The top screw 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 tooth groove on the sliding rod part 111. One end of the first spring 113 abuts against the top screw 115, and the other end abuts against the steel ball 114. Adjusting the top screw 115 can adjust the compression amount of the first spring 113.

[0046] Since the steel ball 114 abuts against the tooth groove on the slide rod 111, the rotating rod 112 can be effectively prevented from "self-rotating" due to external vibrations. The rotating rod 112 will rotate only when an axial active force is applied to the rotating rod 112 (a clicking sound will be emitted during the rotation process).

[0047] The driving structure for applying the axial active force is further described below.

[0048] 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.

[0049] like Fig.11The 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.

[0050] 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.

[0051] 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.

[0052] like Fig.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.

[0053] The following further describes the method of using the present invention.

[0054] After the connection base 2 is sleeved on the connection head 1, each locking rod 11 is coaxial with each locking hole. Two buttons are provided on the connection head 1 or the curtain wall cleaning device to control two rotating cylinders. By controlling the driving disk 31 to rotate, all the locking rods 11 are moved away from each other, and the rotating rod portion 112 is inserted into the locking hole 21 on the connection base 2. During the insertion of the rotating rod portion 112 into the locking hole 21, the buckle 22 is pressed into the mounting hole 211. After the rotating rod portion 112 is extended to the desired position, the spur bevel gear 41 is driven to rotate. Through the linkage between the spur bevel gear 41 and the gear 42, all the rotating rod portions 112 are driven to rotate at the same time. After the locking groove 110 on the rotating rod portion 112 is aligned with the buckle 22, the buckle 22 pops out and snaps into the locking groove 110, completing the assembly of the connection base 2 and the connection head 1.

[0055] When replacing or removing the connecting seat 2, drive the spur bevel gear 41 to rotate in the opposite direction to disengage the locking groove 110 from the buckle 22, then drive the driving disk 31 to reverse, and make all the locking rods 11 approach each other and disengage from the locking hole 21, and then remove the connecting seat 2.

[0056] The present invention can quickly switch the end effector to match the tool, achieving efficient, safe switching and reliable connection of cleaning tools in high-altitude work scenarios. Its unique design of the locking rods that move toward or away from each other synchronously has good linkage. When the connecting seat and the connecting head are assembled, the locking rods move backwards at the same time and are inserted into the corresponding lock hole 21 (assemble first), and the locking rods inserted into the lock hole are rotated along their axial direction at the same time, so that the buckle is snapped into the locking groove (later locked). It not only avoids the risk of accidental falling of the tool, but also simplifies the operation process. The connecting seat can be designed in a modular way, so that the device can be adapted to a variety of cleaning tools, expanding the adaptability of application scenarios, and is particularly suitable for the high-altitude curtain wall cleaning field for the stringent requirements of rapid replacement and operation safety.

[0057] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
