DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 5 In an embodiment of the present invention, a rotatable window cleaning machine platform auxiliary hook device comprises: a main hanging arm 1, a connecting seat 11, a segmented arm 12, a conducting wheel 13, an upper hanger 2 and a rotatable window cleaning machine 3, wherein one end of the main hanging arm 1 is arranged on the roof of a building through a base (not shown in the figure), a guide rail is set on the roof of the building, and the main hanging arm 1 is slidably connected to the guide rail through the base; the other end of the main hanging arm 1 is provided with a connecting seat 11, and the connecting seat 11 is symmetrically inclined and extended to connect the segmented arm 12 on both sides, and the segmented arm 12 The sectional arms 12 are rotatably connected to the connecting seat 11, and a hydraulic rod 14 is connected to one end of the hydraulic rod 14, and one end of the hydraulic rod 14 is connected to the connecting seat 11; the sectional arms 12 are rotatably connected to transmission wheels 13, and two main slings 15 are transmitted and wound on each transmission wheel 13, and the ends of the main slings 15 are connected to hooks, and the upper hanger 2 is connected to the main slings 15 through the hooks on each main sling 15; it should be noted that the retracted and extended lengths of each main sling 15 must be kept consistent, so as to ensure the horizontal stability of the upper hanger;

[0029] The rotary window cleaning machine 3 is located below the upper hanger 2. The four corners of the lower end surface of the upper hanger 2 are connected to the auxiliary slings 21 through the overload monitoring mechanism 4. The lower end of the auxiliary sling 21 is connected to the rotary window cleaning machine 3. The overload monitoring mechanism 4 can monitor the real-time stress condition of each auxiliary sling 21 to ensure that it does not exceed its rated load capacity, thereby preventing a breakage accident caused by overload.

[0030] A rope adjusting unit 5 is provided in the middle of the upper hanger 2. The rope adjusting unit 5 provides a rope pulling action for the main sling 15 every time the main sling 15 shakes and becomes unstable, thereby reducing the shaking amplitude of the main sling 15.

[0031] A center of gravity adjustment component is also provided below the upper hanger 2;

[0032] The rope adjusting unit 5 comprises a central seat 51, inside which is provided a support arm 52 corresponding to the main sling 15, the lower end of the support arm 52 is rotatably connected to the upper hanger 2, the upper end of the support arm 52 is hinged with a support pipe frame 53, on which a wire tube 54 is vertically fixed; the wire tube 54 is sleeved on the main sling 15; an adjusting rod 55 is hinged on the central seat 51, and one end of the adjusting rod 55 is connected to the support arm 52;

[0033] Each of the adjusting rods 55 is synchronously or independently telescopically adjustable, wherein the adjusting rod 55 in the rope adjusting unit 5 offsets or reduces the shaking of the upper hanger 2 by toggling the main sling 15, thereby reducing the shaking amplitude of the rotary window cleaning machine 3; its specific working principle is: when the upper hanger 2 and the main sling 15 are slightly swung by the environmental wind force, the adjusting rod 55 in the opposite direction of the swing is independently controlled to be telescopic, so that the wire tube 54 on the support arm 52 produces a side pull on the main sling 15, and the upper hanger 2 produces a corresponding reverse tilt (opposite to the swing direction), so that one side On the one hand, the center of gravity of the upper hanger 2 is restored, and on the other hand, the rotary window cleaning machine 3 below can be restored horizontally at the same time, so as to achieve a correction effect; and when the upper hanger 2 and the main suspension rope 15 swing greatly due to the influence of environmental wind force, the multiple adjustment rods 55 can make the upper hanger 2 slide up and down under the synchronous and continuous telescopic adjustment. At this time, the upper hanger 2 can quickly regain the vertical balance state, effectively suppress the swing amplitude, and maintain the stability of the working platform (it should be noted that its sliding frequency avoids the swing frequency to prevent larger shaking caused by resonance).

[0034] In this embodiment, the rotation adjustment angle range of the support arm 52 is between -5° and 55°.

[0035] As a preferred embodiment, when the support arm 52 is erected at a maximum tilt angle, the main sling 15 passes through the wire tube 54 in a straight line;

[0036] When the support arm 52 is erected at a minimum tilt angle, the main sling 15 is supported by the wire tube 54 and is distributed in a broken line.

[0037] In this embodiment, the adjusting rod 55 adopts a pneumatic telescopic structure, and a pulse air pipe is also connected to the outside of the adjusting rod 55, so that the adjusting rod 55 can provide a rope-pulling action to the main sling 15 through the wire tube 54 at a high-frequency telescopic frequency. It is particularly suitable for the upper hanger 2 and the main sling 15 to swing greatly due to the influence of environmental wind force. By providing vertical center of gravity adjustment for the upper hanger 2, its left and right swing is reduced.

[0038] In this embodiment, the overload monitoring mechanism 4 includes a bracket body 41, which is transversely fixed on the upper hanger 2, and an outer wheel 42 is rotatably connected to the lower end of one end of the bracket body 41. A hoisting device 44 is also installed on the bracket body 41, and the auxiliary sling 21 is wound around the hoisting device 44 and bypasses the outer wheel 42; a support rod 45 is vertically fixed to the lower end surface of the bracket body 41, and a positioning plate 46 is fixed to the lower end of the support rod 45, and two sliding rods 47 are vertically slidably connected to the positioning plate 46, and a pressure plate is horizontally fixed to the upper end of the sliding rod 47, and an inner wheel 43 is rotatably connected to the lower end thereof;

[0039] The auxiliary sling 21 is wound on the inner wheel 43, a compression spring is connected between the pressure plate and the positioning plate 46, and a resistive pressure sensor is also arranged between the pressure plate and the positioning plate 46, so that the real-time stress condition of each auxiliary sling can be monitored through each resistive pressure sensor.

[0040] In this embodiment, each of the hoisting devices 44 hoists the rotary window cleaning machine 3 through the auxiliary sling 21 when working independently, and the hoisting device 44 cooperates with the rope pulling action of the rope adjusting unit 5 when the rotary window cleaning machine 3 is shaking and unstable by winding and releasing the auxiliary sling 21, thereby maintaining the stability of the main body of the rotary window cleaning machine 3. That is, when the upper hanger 2 produces a vertical center of gravity adjustment (that is, vertical sliding) due to the operation of the rope adjusting unit 5, in order to avoid the synchronous movement of the rotary window cleaning machine 3 below, the multiple hoisting devices 44 can adaptively and synchronously retract and release the auxiliary sling 21, thereby avoiding the rotary window cleaning machine 3 being affected by the pulling of the main sling 15.

[0041] As a preferred embodiment, the center of gravity adjustment assembly includes a plurality of fixed brackets 61, which are symmetrically distributed. The fixed brackets 61 are all distributed along the diagonal lines of the upper hanger 2. The fixed brackets 61 are each provided with a sealing tube 62. The fixed brackets 61 are parallelly connected to the two sides of the sealing tube 62, and a counterweight 64 is slidably mounted on the side rods 63.

[0042] A pneumatic plug 65 is slidably connected inside the sealing tube 62, and a magnetic component is provided at one end of the pneumatic plug 65; and a plurality of electromagnetic adsorption parts are distributed circumferentially on the counterweight block 64, and the electromagnetic adsorption parts are magnetically attracted to the magnetic component when powered on; a pneumatic seat 6 is provided in the middle of the upper hanger 2, and the pneumatic seat 6 is connected to the sealing tube 62 through a plurality of branch pipes 66.

[0043] In the present embodiment, the center of gravity adjustment component controls the sliding adjustment of the counterweight block 64 in the opposite direction when the rotary window cleaning machine 3 is rotated and adjusted and the center of gravity shift occurs, and adaptively fine-tunes the remaining counterweight blocks 64 to enhance the accuracy of the center of gravity callback. The center of gravity adjustment component is mainly arranged on the upper hanger. On the one hand, it will not increase the weight of the auxiliary sling 21. On the other hand, the center of gravity balance of the upper hanger 2 on the main sling 15 can be adjusted through the center of gravity adjustment component, which can improve the reliability and safety of the entire upper hanger system.
