Description

A wall-mounted operating mechanism and window cleaning machine Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to a wall-mounted operating mechanism and a window cleaning machine. Background Technology

[0002] With the development of the domestic economy, more and more buildings are installing window cleaning machines. However, when it is necessary to install window cleaning machines in some low-rise buildings or old buildings, wall-mounted window cleaning machines are more convenient. They only need to be installed along the wall and can be fixed with anchor bolts. The waterproofing of the roof will not be affected. Moreover, the equipment itself does not require much space for passage. Therefore, when renovating old buildings, these projects will use wall-mounted window cleaning machines to meet the cleaning and maintenance of the exterior walls.

[0003] However, traditional wall-mounted window cleaning walking devices all use a four-wheel downward pressing guide rail design (when the guide rail is vertically installed, only two wheels can work normally with force). Therefore, in these designs, in order to have enough friction to drive the equipment, the active running gear is placed at the bottom and the passive running gear is placed at the top, ensuring that the two active running gears can fully bear the force. However, since the running motor of the window cleaning machine has a brake, there will be inertial swaying when starting or stopping. The active running gear is on the lower rail, and its swaying lever arm is the longest (from the lower rail to the highest point of the window cleaning machine), so it will sway more, and the force requirements on the lower rail are higher.

[0004] In summary, there is an urgent need for a reliable wall-mounted operating mechanism.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this utility model is to provide a wall-mounted operating mechanism that effectively reduces the shaking during the start and stop of the window cleaning machine, making the track more reasonably stressed.

[0007] This utility model provides a wall-mounted operating mechanism, including a support assembly, an active operating assembly, a passive operating assembly, and a connecting assembly. The support assembly includes an H-beam upper rail, a C-channel steel lower rail, intermediate support rods, and wall-mounted connecting rods. The H-beam upper rail and the C-channel steel lower rail are arranged parallel and spaced apart. Multiple intermediate support rods are connected between the H-beam upper rail and the C-channel steel lower rail, and wall-mounted connecting rods are vertically connected to both ends of each intermediate support rod. The active operating assembly includes a reducer and a guide wheel, with the output end of the reducer connected to the guide wheel. The passive operating assembly includes a guide wheel with an axle. The connecting assembly includes a connecting rod, an upper transverse rod, a lower transverse rod, an upper extension rod, and a lower extension rod. The upper end of the rod is vertically connected to the upper transverse rod, and both ends of the upper transverse rod are vertically connected to the upper extension rod. The reducer is connected to the other end of the upper extension rod. The lower end extension rod is vertically connected to the lower end of the connecting rod, and the lower extension rod is parallel to the upper extension rod. The lower transverse rod is vertically connected to the other end of the lower extension rod, and the lower transverse rod is parallel to the upper transverse rod. The shafted guide wheel is vertically connected to both ends of the lower transverse rod. The support assembly is disposed between the active running assembly and the passive running assembly. The guide wheel is engaged in the upper opening groove of the upper rail of the H-beam, and the shafted guide wheel is rotatably connected in the lower opening groove of the lower rail of the C-beam.

[0008] Using the above technical solution, the wall-mounted operating mechanism is fixed to the wall by a wall connecting rod. The upper end of the connecting rod is connected to the bracket of the window cleaning machine. When the reducer rotates, it will drive the guide wheel to move in the upper opening groove of the H-beam upper rail, which will drive the connecting component to move, and then drive the bracket and the basket of the window cleaning machine to move.

[0009] Furthermore, the passive running component also includes a guide body with a T-shaped cross-section. The lower end of the guide body is vertically connected to the end of the lower horizontal rod, and both ends of the guide body are connected to the shafted guide wheel.

[0010] Furthermore, the passive running component also includes a horizontal auxiliary wheel and a connecting plate. The connecting plate is connected to the middle of the guide body, and the horizontal auxiliary wheel is rotatably connected to the connecting plate.

[0011] By adopting the above technical solution, when the shafted guide wheel is rotatably connected in the lower opening groove of the C-shaped channel steel lower rail, the horizontal auxiliary wheel rotatably contacts the bottom of the lower opening groove of the C-shaped channel steel lower rail, which improves the stability during operation.

[0012] Furthermore, the active operating component also includes a bearing flange seat and a connecting plate. The bearing flange seat is connected to the end of the reducer away from the guide wheel, and the connecting plate is fixedly connected to the end of the upper extension rod. The bearing flange seat and the connecting plate are connected by bolts and nuts.

[0013] This utility model also provides a window cleaning machine, which includes the above-mentioned wall-mounted operating mechanism.

[0014] Furthermore, the window cleaning machine includes a bracket, the lower end of which is fixedly connected to the upper end of the connecting rod.

[0015] This utility model's wall-mounted operating mechanism is fixed to the wall via a wall-mounted connecting rod, with the upper end of the connecting rod connected to the window cleaning machine's bracket. When the reducer rotates, it drives the guide wheel to move in the upper slot of the H-beam upper rail, thereby moving the connecting assembly, and subsequently the window cleaning machine's bracket and basket. This utility model places the active operating component on top via the H-beam upper rail, while the passive operating component hooks onto the C-beam lower rail, effectively reducing the amount of shaking during the window cleaning machine's start and stop, resulting in more reasonable track stress. This solves the technical problems of difficult on-site construction of the wall-mounted window cleaning machine's guide rail and numerous interference points during on-site operation due to track issues after equipment installation. This utility model simplifies the stress calculation of the equipment (traditional stress calculations always use four-wheel force, which cannot be achieved in actual working conditions; now, active operation equals wheel pressure and vertical pressure, while passive operation's force is the equipment's anti-overturning force), ensuring the stress is consistent with the actual working state and making the equipment safer.

[0034] Example 1

[0035] Figure 1 is a side view of the wall-mounted operating mechanism provided in the embodiment of this utility model, and Figure 2 is a front view of the wall-mounted operating mechanism in Figure 1. Referring to Figures 1 and 2, the wall-mounted operating mechanism provided in this embodiment of the utility model includes a support component 1, an active operating component 2, a passive operating component 3, and a connecting component 4. The support component 1 includes an H-beam upper rail 11, a C-shaped channel steel lower rail 12, intermediate support rods 13, and wall connecting rods 14. The H-beam upper rail 11 and the C-shaped channel steel lower rail 12 are arranged parallel and spaced apart. Multiple intermediate support rods 13 are connected between the H-beam upper rail 11 and the C-shaped channel steel lower rail 12, and the wall connecting rods 14 are vertically connected to both ends of the intermediate support rods 13. The active operating component 2 includes a reducer 21 and a guide wheel 22. The output end of the reducer 21 is connected to the guide wheel 22. The passive operating component 3 includes a guide wheel 31 with a shaft. The connecting component 4 includes a connecting rod 41, an upper transverse rod 42, a lower transverse rod 43, an upper extension rod 44, and a lower extension rod 45. The connecting rod 41 has an upper transverse rod 42 vertically connected to its upper end, and an upper extension rod 44 vertically connected to both ends of the upper transverse rod 42. A reducer 21 is connected to the other end of the upper extension rod 44. A lower extension rod 45 is vertically connected to the lower end of the connecting rod 41, and the lower extension rod 45 is parallel to the upper extension rod 44. A lower transverse rod 43 is vertically connected to the other end of the lower extension rod 45, and the lower transverse rod 43 is parallel to the upper transverse rod 42. A shafted guide wheel 31 is vertically connected to both ends of the lower transverse rod 43. The support assembly 1 is positioned between the active running assembly 2 and the passive running assembly 3. The guide wheel 22 engages in the upper opening slot of the upper H-beam rail 11, and the shafted guide wheel 31 is rotatably connected in the lower opening slot of the lower C-beam rail 12.

[0036] It should be noted that the upper rail is a horizontally placed H-shaped steel upper rail 11, the lower rail is an inverted C-shaped channel steel lower rail 12, and the embedded support (intermediate support rod 13) is a square tube welded combination support that acts directly between the upper and lower rails. The number of supporting square tubes can be increased between the two rails to improve the stress condition of the upper rail.

[0037] Figure 3 is a side view of the window cleaning machine provided in this embodiment of the present invention, and Figure 4 is a front view of the window cleaning machine provided in this embodiment of the present invention. Referring to Figures 3 and 4, when the wall-mounted operating mechanism of the present invention is in use, it is fixed to the wall by the wall connecting rod 14. The upper end of the connecting rod 41 is connected to the bracket 5 of the window cleaning machine. When the reducer 21 rotates, it will drive the guide wheel 22 to move in the upper opening groove of the H-shaped steel upper rail 11, thereby driving the connecting component 4 to move, and then driving the bracket 5 and the basket 6 of the window cleaning machine to move.

[0038] The wall-mounted operating mechanism of this utility model places the active operating component 2 on the upper part via the H-shaped steel upper rail 11, and the passive operating component 3 hooks onto the channel steel of the C-shaped channel steel lower rail 12. This effectively reduces the amount of shaking when the window cleaning machine starts and stops, making the track stress more reasonable. It solves the technical problems of high on-site construction difficulty of the wall-mounted window cleaning machine guide rail and many interference points in on-site operation due to track issues after equipment installation.

[0039] The wall-mounted running mechanism of this utility model simplifies the force calculation of the equipment. Traditional force calculation has always been based on the force exerted by all four wheels, but the actual working conditions cannot achieve this theoretical calculation. Now, the active running force is equal to the vertical pressure of the wheels, and the passive running force is the anti-overturning force of the equipment. The force is consistent with the actual working conditions, making the equipment safer.

Figure 6 is a cross-sectional structural diagram of the passive running component of the wall-mounted running mechanism in Figure 1. Referring to Figures 5 and 6, the passive running component 3 of this utility model also includes a guide body 32. The guide body 32 has a T-shaped cross-section. The lower end of the guide body 32 is vertically connected to the end of the lower transverse rod 43. Both ends of the guide body 32 are connected to the shafted guide wheel 31. Further, the passive running component 3 also includes a horizontal auxiliary wheel 33 and a connecting plate 34. The connecting plate 34 is connected to the middle of the guide body 32, and the horizontal auxiliary wheel 33 is rotatably connected to the connecting plate 34.

[0041] It should be noted that when the shafted guide wheel 31 is rotatably connected in the lower opening groove of the C-shaped channel steel lower rail 12, the horizontal auxiliary wheel 33 rotatably contacts the bottom of the lower opening groove of the C-shaped channel steel lower rail 12, which improves the stability during operation.

[0042] Figure 1 is a side view of the wall-mounted operating mechanism provided in this embodiment of the present invention, and Figure 7 is a plan view of the active operating component of the wall-mounted operating mechanism in Figure 1. Referring to Figures 1 and 7, the active operating component 2 of the present invention further includes a bearing flange seat 23 and a connecting plate 24. The bearing flange seat 23 is connected to the end of the reducer 21 away from the guide wheel 22, and the connecting plate 24 is fixedly connected to the end of the upper extension rod 44. The bearing flange seat 23 and the connecting plate 24 are connected by bolts and nuts.

[0043] Referring further to Figures 3 and 4, this utility model also provides a window cleaning machine, which includes the aforementioned wall-mounted operating mechanism.

[0044] Furthermore, the window cleaning machine includes a bracket 5, the lower end of which is fixedly connected to the upper end of the connecting rod 41.

[0045] As can be seen from the above description, the advantages of this utility model are:

[0046] 1. The wall-mounted operating mechanism of this utility model is fixed to the wall surface by a wall connecting rod 14 during use. The upper end of the connecting rod 41 is connected to the bracket 5 of the window cleaning machine. When the reducer 21 rotates, it will drive the guide wheel 22 to move in the upper opening groove of the H-shaped steel upper rail 11, thereby driving the connecting component 4 to move, and then driving the bracket 5 and the basket 6 of the window cleaning machine to move. The active operating component 2 is placed on the upper part through the H-shaped steel upper rail 11, and the passive operating component 3 hooks the channel steel of the C-shaped channel steel lower rail 12, which effectively reduces the amount of shaking when the window cleaning machine starts and stops, making the track stress more reasonable. This solves the technical problem of the difficulty of on-site construction of the wall-mounted window cleaning machine guide rail and the many interference points on-site due to track problems after equipment installation.

[0047] 2. The wall-mounted running mechanism of this utility model simplifies the force calculation of the equipment. Traditional force calculation has always been based on the force of the four wheels, but the actual working conditions cannot achieve this calculation theory. Now, the active running is equal to the vertical pressure of the wheels, and the force of the passive running is the anti-overturning force of the equipment. The force is consistent with the actual working state, and the equipment is safer.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
