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

[0030] This application discloses a cylindrical V-shaped structure arm head device, such as... Figure 1 As shown, the system includes a column 1 mounted on the boom, two connecting arms 2 mounted on the column 1, a boom head pulley 21 located at the end of the connecting arm 2 furthest from the column 1, and an auxiliary lifting pulley 11 mounted on the column 1. The column 1 is a vertical hollow cylindrical tube, with a cover plate 12 at its upper end to close its opening. The connecting arms 2 are horizontal hollow cylindrical tube piles, both mounted on the column 1 near the cover plate 12, perpendicular to the column 1, and at an angle less than 90 degrees. The auxiliary lifting pulley 11 is located between the two connecting arms 2, with its upper surface lower than the lower surface of each connecting arm 2, and the angles between the auxiliary lifting pulley 11 and the connecting arms 2 are equal. The cable core wire used for lifting the gondola passes through the column 1 and the connecting arm 2, and passes over the arm head pulley 21 to connect with the gondola. The movement of the cable core wire drives the gondola to move. The outer wall of the column 1 also has a clearance hole 13 communicating with its inner cavity. An auxiliary lifting wire for suspending debris passes through the column 1 and the clearance hole 13, and passes over the auxiliary lifting pulley 11, thus enabling the suspension of debris. Without changing the position of the gondola, items are lifted onto the gondola using the auxiliary lifting wire on the auxiliary lifting pulley 11. During lifting, the gondola is less susceptible to external forces, maintaining stability and making its use safer. Furthermore, the cylindrical column 1 enhances the overall stability of the arm head structure.

[0031] When the cable core steel wire passes through the column 1 and the connecting arm 2 and is wound on the arm head pulley 21, the cable core steel wire will abut against the joint between the column 1 and the connecting arm 2, thereby affecting the normal use of the cable core steel wire. Therefore, two deflection pulleys 14 are further arranged on the column 1, and a fixed plate 15 is arranged between the column 1 and the connecting arm 2, and the two deflection pulleys 14 are arranged between the column 1 and the connecting arm 2 and are rotatably connected to the fixed plate 15, and part of the deflection pulley 14 is embedded in the column 1 and the connecting arm 2, and the rotation axis of the deflection pulley 14 is in the same horizontal plane as the rotation axis of the arm head pulley 21. Before the cable core steel wire needs to pass through the arm head pulley 21, it will abut against the deflection pulley 14, so that the cable core steel wire will not directly abut against the joint between the column 1 and the connecting arm 2, and the normal use of the cable core steel wire will not be easily affected.

[0032] In order to prevent the auxiliary hoisting steel wire from being too close to the outer wall when hoisting the object, the column 1 is further rotatably connected with an auxiliary hoisting guide wheel 16, and the auxiliary hoisting guide wheel 16 is arranged on the side of the auxiliary hoisting pulley 11 close to the column 1, so that the auxiliary hoisting pulley 11 can be arranged away from the column 1. Part of the auxiliary hoisting guide wheel 16 is embedded in the column 1, and the upper end of the auxiliary hoisting guide wheel 16 is lower than the auxiliary hoisting pulley 11, and the auxiliary hoisting steel wire passes through the auxiliary hoisting guide wheel 16 and the auxiliary hoisting pulley 11 in sequence. By arranging the auxiliary hoisting pulley 11 away from the column 1, the auxiliary hoisting steel wire wound on the auxiliary hoisting pulley 11 can be away from the outer wall, so that the object hoisted by the auxiliary hoisting steel wire can also be away from the outer wall, reducing the occurrence of collision.

[0033] Two mounting plates 17 parallel to the axis of the column 1 are further arranged on the outer wall of the column 1, and the two mounting plates 17 are arranged on the two sides of the auxiliary hoisting pulley 11, and the auxiliary hoisting pulley 11 and the auxiliary hoisting guide wheel 16 are rotatably connected to the two mounting plates 17. The ends of the two mounting plates 17 away from the column 1 are fixedly connected with a limiting plate 171, and the upper end of the limiting plate 171 is flush with the upper end surface of the mounting plate 17, and the lower end of the limiting plate 171 is flush with the lower end surface of the mounting plate 17, so as to limit the position of the auxiliary hoisting steel wire wound on the auxiliary hoisting pulley 11 by the limiting plate 171, so that the auxiliary hoisting steel wire is not easy to move away from the column 1, and the auxiliary hoisting steel wire can stably hoist the object.

[0034] In order to prevent sundries from falling into the auxiliary hoisting pulley 11, the upper ends of the two mounting plates 17 are further provided with a protective plate 172, which closes the upper end openings of the two mounting plates 17, and the protective plate 172 is fixedly connected with the fixed plate 15, so as to enhance the mounting plate 17, so that the mounting plate 17 is not easy to deform under stress, and the mounting plate 17 can also block the sundries from falling on the auxiliary hoisting pulley 11 from above, so that the sundries are not easy to affect the rotation of the auxiliary hoisting pulley 11.

[0035] In order to prevent sundries from entering the auxiliary hoisting pulley 11 when the auxiliary hoisting wire is being wound, the lower end of the limiting plate 171 is further provided with a scraper 173, which is horizontally arranged. The scraper 173 is provided with a cleaning hole 174, through which the auxiliary hoisting wire can slide, so that the scraper 173 can prevent the sundries from directly contacting the auxiliary hoisting pulley 11, and the normal rotation of the auxiliary hoisting pulley 11 is not easily affected.

[0036] As shown in Figure 2 The lower end of the column 1 is provided with a flange, and the swing support includes an inner ring 311 coaxially arranged below the flange and an outer ring 312 arranged on the hoisting arm of the window cleaning machine. The inner ring 311 and the outer ring 312 are connected through a bearing, and the auxiliary hoisting wire and the cable core wire can be arranged in the inner ring 311. The outer wall of the outer ring 312 is coaxially provided with an outer gear ring, and the gear 33 can be engaged with the outer gear ring. The driving member 32 is selected as an electric motor in this embodiment. The motor is provided with a speed reducer, which is arranged at the upper end of the flange. The output shaft of the motor is connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is connected with the gear 33, so as to drive the gear 33 to rotate.

[0037] The implementation principle of the embodiment is that when the crane is working, the auxiliary hoisting wire can be vertically moved under the driving of the winch, so as to vertically move the hoisted object, and realize hoisting the object to the working crane.

[0038] The embodiments of the specific embodiment are the preferred embodiments of the present application, but do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
