DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention.

[0021] like Figure 1 to Figure 5 As shown, the winch-type gate opener with a dust removal device includes a mounting plate 100, a square groove 101 is provided on the front side of the mounting plate 100, the square groove 101 provides space for lowering the wire rope, a power mechanism 102 is fixedly installed on the rear side of the mounting plate 100, the power mechanism 102 provides a power source for the gate opener, and also has the function of decelerating and increasing torque, two symmetrical support frames 103 are fixedly installed on the front side of the power mechanism 102, the two support frames 103 are located on both sides of the square groove 101, a drum 104 is rotatably installed between the two support frames 103, the drum 104 is used to store the wire rope, a protective cover 105 is rotatably installed on the drum 104, the protective cover 105 can protect the drum 104, and can also effectively prevent dust from adhering to the wire rope, the protective cover 105 is provided with a through groove, and is provided with a cleaning mechanism, the cleaning mechanism can remove dust adhering to the surface when storing the wire rope.

[0022] The cleaning mechanism includes two movable plates 106, which are symmetrically arranged on both sides of the through groove. The two movable plates 106 are hingedly installed on the protective cover 105. The hinged installation can ensure that the movable plates 106 move together with the wire rope to prevent the wire rope from bending and reduce unnecessary force on the wire rope. A guide groove 107 is provided on the movable plate 106, and a slag cleaning sleeve 108 is provided below the guide groove 107. A scraper 109 is hinged on the upper end of the inner wall of the slag cleaning sleeve 108. The scraper 109 can scrape off dust on the wire rope. The lower end surface of the scraper 109 is fixedly connected to a telescopic rod 110, and the other end of the telescopic rod 110 is fixedly connected to the inner wall of the slag cleaning sleeve 108. When the telescopic rod 110 is used to recycle the wire rope, the scraper 109 can fit the surface of the wire rope better.

[0023] The guide groove 107 is provided with a plurality of connecting components, which include a slider 200. The inward side of the slider 200 is universally hinged with a connecting rod 201. The slag cleaning sleeve 108 is universally hinged between the connecting rods 201 in two opposite connecting components. The slider 200 can ensure that the slag cleaning sleeve 108 moves with the wire rope, and the universal hinge can realize the slag cleaning sleeve 108 to move at multiple angles with the wire rope.

[0024] The telescopic rod 110 includes a sleeve 1101, in which a spring 1102 is arranged. One end of the spring 1102 is fixedly mounted on the inner wall of the sleeve 1101, and the other end of the spring is fixedly connected to a movable rod 1103. The spring 1102 provides thrust for the movable rod 1103, so that the scraper 109 can better fit the wire rope.

[0025] A limit block 1104 is fixedly installed on one end of the movable rod 1103 connected to the spring, and a baffle 1105 is fixedly installed on the end of the sleeve 1101 away from the inner wall of the sleeve 1101. The setting of the limit block 1104 and the baffle 1105 can prevent the movable rod 1103 from falling off from the sleeve 1101 when the wire rope is retracted.

[0026] The width of the square groove 101 is greater than the length of the drum 104, and its purpose is to provide enough space for lowering the wire rope.

[0027] Working principle: when the wire rope is lowered, the slag cleaning sleeve 108 moves with the wire rope under the action of the connecting assembly, and the movable rod 1103 is compressed and shrinks to a size that fits the wire rope; when the wire rope is stored, the stored wire rope enters the drum 104 through the slag cleaning sleeve 108. When the wire rope passes through the slag cleaning sleeve 108, due to the friction between the wire rope and the scraper 109, the bottom of the scraper 109 is subjected to an upward force, so that the scraper 109 fits the wire rope, so that the scraper 109 can remove the dust attached to the wire rope, thereby solving the problem of long-term accumulation of dust, which will cause resistance to the wire rope when in use.

[0028] In this embodiment, by setting up the cleaning mechanism and the connecting assembly, the problem of long-term accumulation of dust causing resistance of the wire rope during use is solved, thereby making the operation and lifting of the wire rope more convenient and ensuring the normal operation of the winch hoist.

[0029] The embodiments described above are only some of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
