Detailed Description

In order to clearly illustrate the technical features of the present solution, the present invention is explained in detail below by means of specific embodiments and with reference to the attached drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-3, for the general improvement of the existing cable pulley of the trash cleaning machine to avoid the jumping and falling in the hanging rail 1, a hook bolt 4 is mainly arranged between two auxiliary pulleys 3 of the auxiliary pulley blocks at two sides of the pulley 2, when the pulley is likely to jump and fall due to a series of problems such as misoperation or tilting of a hoisted object, the pulley can be limited to a certain extent, but the hook bolt cannot be locked and is easy to rotate, the pulley 2 cannot be effectively prevented from jumping and falling, and the stress influences the pressure at the bending part of the flat cable in the process, so that the breakage rate at the position of the flat cable is increased.

As shown in fig. 4-5, the anti-jumping device for a cable pulley of a trash remover comprises a hanging rail 1 and a pulley 2 arranged along the hanging rail in a sliding manner, pulleys traveling along the hanging rail are arranged on base plates on two sides of the pulley, auxiliary pulley blocks arranged in a matching manner with the hanging rail are oppositely arranged on two sides of the bottom surface of the pulley, and each auxiliary pulley block comprises two auxiliary pulleys 3 arranged at intervals along the sliding direction of the pulley; a cable hanger 5 is connected below the pulley, and a flat cable 6 is wound on the cable hanger; and a support plate is also connected between the pulley and the cable hanger, and the top end of the support plate is fixedly connected with the bottom surface of the pulley in a welding manner. The support plate is for link up the support frid that sets up along coaster slip direction, specifically is U type frid 7, the body of rod is worn to establish and is fixed in on two vertical lateral walls of U type frid. The U-shaped groove plate is arranged on the bottom surface of the pulley between the two auxiliary pulley blocks; the outer end of the rod body penetrates through the space between the two auxiliary pulleys of each auxiliary pulley block and extends outwards. The body of rod is full silk screw rod 8, and full silk screw rod links to each other with U type frid detachable, specifically is two vertical lateral walls of U type frid are worn out and are fixed with U type frid through fastening bolt to the both ends of full silk screw rod.

A certain gap is reserved between the top surface of the full-thread screw 8 and the bottom surface of the hanger rail, so that the normal running of the pulley sliding along the hanger rail can be ensured, and the full-thread screw is prevented from being limited by the bottom surface of the hanger rail to generate resistance when the pulley has a tendency of jumping.

The bottom end of the U-shaped groove plate 7 is fixedly connected with the cable hanger 5 through a threaded fastener. The cable hanger is a cylindrical cable hanger, and the inner diameter of the cylindrical cable hanger is not less than 40 mm. The hanging rods 9 are arranged on two sides of the bottom wall of the U-shaped groove plate, hanging holes are correspondingly arranged on two sides of the cable hanging bracket, and the hanging rods penetrate through the hanging holes and are locked through threaded fasteners to be fixedly connected with the U-shaped groove plate.

And (3) installation and use: on former coaster 2 and cable hanger 5 are connected the basis, add a U type frid 7, the top fixed welding of U type frid mixes between the wheelset in the supplementary of coaster bottom, sets up the screw hole on two vertical lateral walls of U type frid, wears to establish and connects full silk screw rod 8 to screw up fastening bolt in order to fix full silk screw rod inside and outside the vertical lateral wall of U type frid. The hanger rods on two sides of the bottom wall of the U-shaped groove plate are connected with the hanging holes on two sides of the cable hanger 5 and are locked and fixedly connected through threaded fasteners. The inner diameter of the cable hanger is increased to 40mm and the flat cable 6 is arranged by bypassing between the cable hanger and the bottom wall of the U-shaped channel plate. The device is in the coaster operation in-process, in case the tendency of jumping to fall appears, receives the resistance of the full-thread screw rod on the U type frid, can be better avoid jumping out the hanger rail, and the at utmost has avoided the coaster to jump the driving card of falling constitution and pause or other troubles, and overall structure design is ingenious, simple, when not influencing the normal work of coaster, is showing and has improved the jump that present trash cleaning machine original-mounted cable coaster often appears in daily operation and has fallen the situation.

The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.

The parts of the present invention not described in detail are the known techniques of those skilled in the art.
