Technical Field
[0001] The utility model relates to a rope pressing device structure for preventing steel wire ropes from skipping on a dynamic compactor, specifically to a scheme for preventing steel wire ropes from skipping by means of a rope pressing device structure. The rope pressing device is realized by a roller and a spring to prevent the steel wire rope from skipping. Background Art
[0002] A dynamic compactor is a machine for compacting loose soil. It hoists a rammer to a certain height by a steel wire rope through a winch, and then allows it to fall freely for ramming. With the popularization of the single-drawing method, it is a non-hammer-detaching construction method. However, when the hammer with the steel wire rope falls to the ground instantaneously, the brake is stepped on at this time and the winch does not move. However, at this time, the steel wire rope will extend a little more. Due to the inertial rebound of the steel wire rope, the steel wire rope will jump up and down on the winch. During this jumping process, the steel wire rope may get out of the rope groove of the winch drum and rub against the convex edge between the rope grooves, which will cause wear of the steel wire rope and is not conducive to the service life of the steel wire rope.
[0003] The market needs to provide a structure that can greatly reduce the jumping of the steel wire rope, keep it in the rope groove of the winch, and protect the steel wire rope. Therefore, how to design such a structure has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model
[0004] The purpose of the present utility model is precisely to provide a rope pressing device structure for preventing steel wire ropes from skipping, which can meet the requirement that the steel wire ropes do not come off the ropes during single-drawing construction of a dynamic compactor. The present utility model organically combines the roller, spring, and limit structure of the rope pressing device, and realizes the prevention of steel wire rope skipping through the roller and spring of the rope pressing device, restricts the steel wire rope within a certain area, and prevents the steel wire rope from jumping out of the rope groove during single-drawing, thereby damaging the steel wire rope.
[0005] The purpose of the present utility model can be achieved by the following technical measures:
[0006] The structure of the rope pressing device for the anti-wire rope skipping rope of the present utility model includes a connecting vertical plate structure composed of a bracket and left and right side plates fixedly connected to both ends of the bracket, a roller structure installed at the front ends of the left and right side plates, the ends of the left and right side plates are respectively combined with the mounting base in a hinged manner, and the mounting base is fixedly installed on the hoisting frame through a connecting piece; limit structures are respectively installed on the outer sides of the lower parts of the left and right side plates to keep the roller and the wire rope in a state of being seemingly in contact but not actually in contact, so as to prevent the roller from applying pressure to the wire rope; adjusting rod structures are respectively arranged on the left and right side plates at the rear of the roller structure; the roller structure includes a roller shaft installed in the shaft holes processed at the front ends of the left and right side plates in a static fit manner, short rollers are respectively installed on the left and right extension sections of the roller shaft extending outside the left and right side plates through bearings, and a long roller is installed on the roller shaft section between the left and right side plates through a bearing, and the functions of the long roller and the short roller are to limit the jumping range of the wire rope; the adjusting rod structure includes a connecting fork and a spring for damping the jumping of the wire rope, the connecting fork is installed on the corresponding side plate through a connecting shaft and a nut Ⅰ for adjusting the up and down position of the connecting fork, one end of the spring is combined with the lower end of the connecting fork, and the other end is combined with the hoisting frame; the nut Ⅰ is used to adjust the up and down position of the connecting fork, thereby adjusting the length of the spring and playing a role in adjusting the damping magnitude up and down.
[0007] In the present utility model, the limit structure is composed of a limit plate, a bolt and a nut; the bolt is installed on the connecting plate through the nut, and the connecting plate is fixedly combined with the outer vertical surface of the corresponding side plate of the connecting vertical plate structure; the limit plate is fixed on the main hoisting frame through the base threaded hole on the main hoisting frame; the bottom of the bolt abuts against the limit plate, and the distance between the vertical plate structure and the limit plate is adjusted through the nut (i.e., adjusting the front inclination angle of the connecting vertical plate structure), so that the roller of the rope pressing device and the wire rope are always in a state of being seemingly in contact but not actually in contact, so as to prevent the roller from applying pressure to the wire rope.
[0008] Furthermore, the spring in the present utility model plays a damping role, the roller structure plays a device for limiting the jumping of the wire rope, and the limit structure plays a role in limiting the contact distance between the roller and the wire rope, ensuring that the roller and the wire rope are in a state of being seemingly in contact but not actually in contact, so as to prevent the roller from applying pressure to the wire rope.
[0009] The present utility model transfers the energy of the wire rope jumping to the spring through the roller, the left and right side plates and the adjusting rod structure. The spring has a damping effect on the jumping of the wire rope. The spring absorbs the energy of the wire rope jumping and controls the jumping of the wire rope within a smaller range, avoiding the wire rope from jumping into other rope grooves due to large jumping and cutting the rope grooves, thereby affecting the service life of the wire rope.
[0010] When the dynamic compactor is operating under the dynamic compaction condition normally, the number of layers of the wire rope is greater than 1 layer at this time. In this condition, the rope pressing device is not required to participate, and the spring needs to be disengaged from the winch frame.
[0011] The beneficial effects of the present utility model are as follows:
[0012] The present utility model can select whether the rope pressing device participates in the work according to the needs of different working conditions of the dynamic compactor. In the single-drawing working condition, the spring is connected to the winch frame with a pin shaft, and the limit structure is adjusted to prevent the drum from pressing the wire rope. In this state, the wire rope is prevented from jumping out of the rope groove. Description of the Drawings
