Description

Technical Field

[0001] This application relates to the technical field of window cleaning machines, and in particular to a single-arm head with a left-right switching glass hanging point configuration. Background Technology

[0002] When cleaning or replacing the glass on the exterior of a curtain wall, it is usually necessary to use a glass hoist or a gondola to lift the glass for cleaning. However, due to the increasingly complex decoration of modern curtain walls, such as the current space limitations of protruding and recessed sections, the boom head used for hoisting on the telescopic arm connected to the window cleaning machine cannot be rotated into position. This makes it difficult to move the glass or gondola lifted by the boom head to the location where the glass needs to be replaced or cleaned, and makes it difficult for the boom head to work under the complex working conditions of the curtain wall.

[0003] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0004] In order to enable the boom head to lift glass and other materials to the required position as needed, this application provides a single boom head with a left-right switching glass lifting point.

[0005] This application provides a single-arm head with a left-right switching glass suspension point configuration, employing the following technical solution:

[0006] A single-arm head with a left-right switching glass lifting point includes an arm head for connecting to a telescopic arm of a window cleaning machine, and a glass hanger connected to the arm head for lifting. The glass hanger includes a mounting frame fixed to the arm head, a plurality of guide wheels rotatably connected to the mounting frame, an adjusting frame detachably connected to the mounting frame, and lifting wheels rotatably connected to the adjusting frame. The mounting frame is arranged perpendicular to the length direction of the arm head, the adjusting frame is detachably installed at both ends of the mounting frame, the rotation axis of the lifting wheels is parallel to the length direction of the arm head, and the rotation axis of the guide wheels is vertically arranged.

[0007] By adopting the above technical solution, when the location to be hoisted changes and the boom head is difficult to rotate into place, the position of the adjusting frame can be moved to the other side of the boom head, so that the hoisted object can be moved to the required position.

[0008] Optionally: the mounting frame is hollow with openings at both ends, part of the guide wheel is embedded in the mounting frame, the adjusting frame is open at the lower end, the adjusting frame is connected to the inner cavity of the mounting frame, and the lifting wheel is located in the inner cavity of the adjusting frame.

[0009] By adopting the above technical solution, the wire rope used for hoisting can be wound around the guide wheel from inside the mounting frame. The wire rope can also be moved from the connection between the mounting frame and the adjusting frame to the adjusting frame and wound around the hoisting wheel, so that the wire rope is not directly exposed outside the mounting frame and the adjusting frame, making it less likely for the wire rope to get tangled in debris when moving, and making the movement of the wire rope less affected.

[0010] Optionally: The mounting bracket has mounting edges around its opening at both ends, and the adjusting bracket has an adjusting edge around its opening near the end face of the mounting bracket. The mounting edges can be aligned with the adjusting edges. Fastening bolts are threaded through the mounting edges and the adjusting edges, and fastening nuts are threaded onto the fastening bolts.

[0011] By adopting the above technical solution, the connection area between the mounting frame and the adjusting frame is increased by utilizing the cooperation between the mounting edge and the adjusting edge. At the same time, the connection between the mounting frame and the adjusting frame is realized by the cooperation of the fastening bolts and fastening nuts, which makes it more convenient to disassemble and install the adjusting frame on the mounting frame, and also enhances the connection strength between the mounting frame and the connecting frame.

[0012] Optionally: the mounting is provided with a plurality of mounting reinforcing ribs along the mounting frame, and the adjustment is provided with a plurality of adjustment reinforcing ribs along the adjustment frame.

[0013] By adopting the above technical solution, the connection strength between the mounting frame and the mounting edge is enhanced by using installation reinforcing ribs, and the connection strength between the adjusting frame and the adjusting ribs is enhanced by using adjustment reinforcing ribs. As a result, when the mounting frame and the adjusting frame are connected, the mounting edge and the adjusting edge are not prone to deformation, and the mounting frame and the adjusting frame can be stably connected.

[0014] Optionally: A guide rope pulley is provided on the arm head near the telescopic arm of the window cleaning machine, and the wire rope wound on the guide rope pulley and the guide wheel is parallel to the arm head.

[0015] By adopting the above technical solution, the guide rope pulley is used to guide the movement direction of the wire rope, so that the wire rope will not directly rub against the boom head when moving, thus enabling the wire rope to move stably and making it less prone to wear during movement.

[0016] Optionally: Two fixing blocks are fixed on the arm head. The fixing blocks are located on both sides of the mounting frame and fixed to the mounting frame. Extension blocks are provided at both ends of the fixing blocks. The extension blocks are fixed to the two side walls of the arm head respectively.

[0017] By adopting the above technical solution, the contact area between the arm head and the mounting frame is further enhanced by the extension block, thereby strengthening the connection between the extension block and the arm head, making it less likely for the mounting frame to deform relative to the arm head under stress.

[0018] Optionally: The mounting bracket has a clearance groove that communicates with its inner cavity on the side wall away from the guide rope pulley, and the clearance groove passes through both ends of the mounting bracket and the fixing block.

[0019] By adopting the above technical solution, when the adjustment frame is moved from one end of the mounting frame to the other end of the mounting frame, the wire rope can be moved along the relief groove and transferred to the opening at the other end of the mounting frame. This eliminates the need to re-thread the wire rope when the adjustment frame is moved, making the adjustment of the position of the adjustment frame more convenient.

[0020] Optionally: A positioning tube is provided on the end face of the adjustment frame near the mounting frame, the positioning tube passes through the mounting frame, and the outer wall of the positioning tube is in contact with the inner wall of the mounting frame.

[0021] By adopting the above technical solution, the positioning tube is inserted into the mounting groove, making it easier to align the adjustment bracket and the mounting bracket during installation. Furthermore, when tightening the upper and lower end faces of the mounting bracket, the positioning tube can be used to limit the position of the upper and lower end faces of the mounting bracket, making the positioning of the mounting bracket more accurate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the location to be hoisted changes and the boom head is difficult to rotate into place, the position of the adjustment frame can be moved to the other side of the boom head, so that the hoisted object can be moved to the required position.

[0024] 2. When moving the adjustment frame from one end of the mounting frame to the other end, the wire rope can be moved along the relief groove and transferred to the opening at the other end of the mounting frame, so that the wire rope does not need to be re-threaded when the adjustment frame is moved, making the adjustment of the position of the adjustment frame more convenient.

Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a configuration of a left-right switching glass suspension point type single-arm head, such as... Figure 1 and Figure 2 As shown, the system includes an arm head 1 for connection to the telescopic arm of a window cleaning machine, and a glass hanger 4 connected to the arm head 1 for hoisting. The arm head 1 is connected to the telescopic arm via a rotating assembly 3. The rotating assembly 3 includes an inner ring 31 fixed to the telescopic arm, an outer ring 32 fixed to the arm head 1, a motor 33 fixed to the telescopic arm, and a gear 34 disposed on the output shaft of the motor 33. The inner ring 31 and the outer ring 32 are coaxially arranged, and the outer ring 32 is sleeved outside the inner ring 31 and rotates. An external gear ring is coaxially arranged on the outer wall of the outer ring 32, and the external gear ring meshes with the gear 34, thereby enabling the motor 33 to drive the arm head 1 to rotate.

[0031] like Figure 1 As shown, the glass hanger 4 includes a mounting frame 41 fixed to the upper end face of the arm head 1, two guide wheels 42 rotatably connected to the mounting frame 41, an adjusting frame 43 detachably connected to the end of the mounting frame 41, and lifting wheels 44 rotatably connected to the adjusting frame 43. The mounting frame 41 is a hollow rectangle with openings at both ends, and is perpendicular to the arm head 1. The mounting frame 41 has a connecting groove 411 with an opening on the side wall near the telescopic arm, communicating with its inner cavity. Two mounting plates 412 are also provided on the side wall of the mounting frame 41 with the connecting groove 411. The two mounting plates 412 are respectively provided on the upper and lower sides of the connecting groove 411, and the side walls of the mounting plates 412 that are close to each other are flush with the upper and lower inner walls of the connecting groove 411. Two guide wheels 42 are rotatably connected between two mounting plates 412. The rotation axes of the two guide wheels 42 are vertically arranged, and the two guide wheels 42 are arranged along the length of the mounting frame 41. Parts of the two guide wheels 42 are embedded in the mounting frame 41.

[0032] like Figure 1 and Figure 3As shown in the figure, mounting edges 413 are provided around the openings on both end faces of the mounting bracket 41. A number of mounting reinforcing ribs 414 are provided between the mounting edges 413 and the mounting bracket 41 to enhance the connection strength between the mounting edges 413 and the mounting bracket 41. The adjusting bracket 43 is provided in a rectangular hollow shape. The end face of the adjusting bracket 43 close to the mounting bracket 41 and its lower end face are both provided with openings. An adjusting edge 431 is provided along the opening on the end face of the adjusting bracket 43 close to the mounting bracket 41. The adjusting edge 431 has the same size as the mounting edge 413, and the adjusting edge 431 can be abutted against the mounting edge 413. A number of adjusting reinforcing ribs 432 are also provided between the adjusting edge 431 and the adjusting bracket 43 to enhance the connection strength between the adjusting edge 431 and the adjusting bracket 43, so that deformation is not likely to occur between the adjusting bracket 43 and the adjusting edge 431. A number of fastening bolts 45 are commonly penetrated between the mounting edge 413 and the adjusting edge 431. Threaded fastening nuts 46 are provided on the fastening bolts 45. The mounting bracket 41 and the adjusting bracket 43 can be stably connected through the cooperation of the fastening bolts 45 and the fastening nuts 46. A positioning tube 433 is also fixed on the end face of the adjusting bracket 43 close to the mounting bracket 41. The positioning tube 433 penetrates through the mounting bracket 41, and the outer wall of the positioning tube 433 can be fitted with the inner wall of the mounting bracket 41, thereby further enhancing the connection strength between the mounting bracket 41 and the adjusting bracket 43.

[0033] The hoisting wheel 44 is rotatably connected inside the adjusting bracket 43. The lower end of the hoisting wheel 44 is located below the lower end face of the adjusting bracket 43. The rotation axis of the hoisting wheel 44 is arranged parallel to the length direction of the arm head 1. At the same time, the steel wire rope wound around the hoisting wheel 44 and the guide wheel 42 can be arranged horizontally. An anti-collision bracket 47 is also provided at one end of the adjusting bracket 43 far from the mounting bracket 41. The anti-collision bracket 47 is arranged in an inclined shape like the Chinese character 'Ri'. The upper end of the anti-collision bracket 47 is fixed to the adjusting bracket 43. The lower end of the anti-collision bracket 47 is arranged directly below the steel wire rope passing around the hoisting wheel 44, so that the steel wire rope can pass through the lower end of the anti-collision bracket 47, achieving the effect of preventing the hoisted object from directly hitting the hoisting wheel 44.

[0034] ​

[0035] To ensure the mounting bracket 41 is stably fixed to the arm head 1, two fixing blocks 11 are welded and fixed to the arm head 1. The two fixing blocks 11 are arranged along the length of the arm head 1, and each of the two fixing blocks 11 has an integrally formed extension block 111 at both ends. The two extension blocks 111 are also welded and fixed to the side wall of the arm head 1. The mounting bracket 41 is positioned between the two fixing blocks 11 and is fixed to the fixing blocks 11 by bolts. The fixing blocks 11 increase the contact area between the mounting bracket 41 and the arm head 1, thereby enhancing the connection strength between the mounting bracket 41 and the arm head 1.

[0036] like Figure 1 As shown, in order to ensure that the wire rope can stably enter between the two guide wheels 42, a guide rope pulley 12 is rotatably connected at the upper end of the boom head 1 near the telescopic boom. At the same time, the wire rope wound above the guide rope pulley 12 and on the guide wheel 42 is parallel to the boom head 1, so that the wire rope can be stably connected to the guide wheel 42 and the guide rope pulley 12.

[0037] Two gondola pulleys 13 are rotatably connected to the lower end of the boom head 1. The two gondola pulleys 13 are respectively set close to both ends of the boom head 1, so that the gondola wire can pass around the gondola pulleys 13 and connect to the gondola for hoisting the gondola.

[0038] The implementation principle of this embodiment is as follows: When it is necessary to hoist the glass, the wire rope passes around the guide wheel 42 and the hoisting wheel 44 to drive the glass to move. When it is necessary to change the position of the adjusting frame 43, the fastening bolt 45 is removed and the reinforcing bolt 48 is removed from the mounting frame 41. The adjusting frame 43 is transferred to the other end of the mounting frame 41, and the wire rope is transferred from the relief groove 415 to the other end of the mounting frame 41. After the adjusting frame is installed on the other end of the mounting frame 41, the reinforcing bolt is locked to complete the adjustment of the position of the adjusting frame 43.

[0039] The embodiments described in this specific implementation are 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.
