DETAILED DESCRIPTION

[0016] The utility model will be further described below in combination with the drawings and examples, but it is not as the basis for limiting the utility model.

[0017] Example: an anti-jumping groove protection device for steel wire ropes and cables, the steel wire rope and the cable are wound on a roller, and the roller is reversely rotated to realize the winding and sending of the steel wire rope and the cable, as shown in the drawingsFigure 1 As shown, the anti-jumping protection device comprises a bottom plate 1, symmetrically arranged mounting seats 2 are welded on the bottom plate 1, the mounting seats are C-shaped in cross section, and the openings of the two mounting seats are oppositely arranged, the non-closed profile facilitates the maintenance of the components, detection rods 3 are movably connected on the mounting seats 2 through the openings, connecting seats 4 are assembled on the outer ends of the detection rods 3, contact rollers 5 for contacting the steel wire rope and the cable are rotatably connected on the two side connecting seats 4 through bearings; a limit controller 6 corresponding to the inner ends of the detection rods 3 is assembled on the mounting seat 2, the limit controller 6 is electrically connected with the working circuit of the roller, the limit controller is an electromechanical positioner, the end thereof has a push rod, the push rod is in contact with the inner end of the detection rod and moves, the moved push rod hits the internal micro switch, and then sends a signal to the working circuit of the roller, which is a technical means familiar and mastered by those skilled in the art, and will not be described here, the roller working circuit receiving the signal only reverses (i.e. sends out the steel wire rope and the cable), until the limit controller signal disappears; the detection rod 3 is integrally formed with a protrusion 7, a spring 8 connected with the mounting seat 2 is fixed on the protrusion 7, the spring adopts a low stiffness coefficient to avoid excessive extrusion; as shown in the accompanying drawings, Figure 2 As shown, the end of the detection rod 3 is welded with a connecting piece 9, an installation groove 10 is opened at the end of the connecting piece 9, and a guide block 11 is integrally formed in the installation groove 10; a guide piece 12 is integrally formed on the connecting seat 4, a guide groove 13 adapted to the guide block 11 is opened on the guide piece 12, the guide block can slide in the guide groove, and then the relative movement of the connecting piece and the guide piece is realized, when the jumping of the roller occurs on one side, the contact roller can be inclined without moving as a whole, and then the accurate sensing of the detection rod and the limit controller on the corresponding side is realized, the maintenance personnel can quickly judge the fault side of the roller by distinguishing the signals sent by the two side limit controllers, and the practicability is improved; the guide block 11 is a cylindrical block, which improves the smoothness of the movement in the guide groove; the groove surface of the installation groove 10 is attached to the upper and lower surfaces of the guide piece 12, which limits the guide piece and avoids the jumping of the contact roller, and improves the stability of the structure; the limit plate 14 is arranged on the side of the corresponding guide piece 12 on the mounting seat 2, the movement range of the contact roller is limited by the contact of the two side limit plates and the guide pieces, which ensures that it can be accurately reset and improves the reliability of the work; the corners of the connecting piece 9 and the guide piece 12 are all rounded; the two detection rods 3 are parallel, which is used to ensure the consistency of the movement distances of the two; the support column 15 is welded on the bottom plate 1, the support sleeve 16 movably connected with the middle part of the detection rod 3 is integrally formed on the support column 15, which supports the middle part of the detection rod, avoids deformation, and ensures the reliability of the movement.

[0018] Working principle: when in use, the contact roller 5 is in close contact with the steel wire rope and cable on the drum under the elastic action of the spring 8, and rotates with the drum, ensuring that it does not hinder the normal winding and unwinding of the steel wire rope and cable; when the steel wire rope and cable jump, the jumping rope and cable will push the contact roller 5, and since the contact roller 5 is connected with the detection rod 3 through the connecting seat 4, the movement of the contact roller 5 further drives the detection rod 3 to move on the mounting seat 2.

[0019] When the detection rod 3 moves, the protrusion 7 thereon will compress or stretch the spring 8, and the spring 8 plays a buffering and resetting role; at the same time, the inner end of the detection rod 3 gradually approaches the limit controller 6, and when the inner end of the detection rod 3 reaches the preset limit position of the limit controller 6, the limit controller 6 triggers an action, and then sends a signal to the working circuit of the drum, and the working circuit of the drum receiving the signal will perform a preset operation, such as only reversing (i.e. sending out the steel wire rope and cable), until the limit controller 6 signal disappears, so as to avoid further jumping or damage of the steel wire rope and cable.

[0020] In addition, the structure design of the connecting piece 9 at the end of the detection rod 3 and the guide 12 on the connecting seat 4 makes the contact roller 5 tilt without moving as a whole when unilateral jumping occurs on the drum, and then accurately senses the detection rod 3 and the limit controller 6 on the corresponding side, so that the maintenance personnel can quickly judge the fault side of the drum by distinguishing the signals sent by the two limit controllers 6, thereby improving the troubleshooting efficiency.

[0021] The limit plates 14 on the mounting seat 2 limit the guide 12, and the contact range of the contact roller 5 is limited by the contact between the limit plates 14 on both sides and the guide 12, so that the contact roller 5 can be accurately reset after the steel wire rope and cable return to the normal position, thereby improving the reliability of the work; the support column 15 and the support sleeve 16 on the bottom plate 1 support the middle part of the detection rod 3, so as to avoid deformation of the detection rod 3 due to stress, and ensure the stability and reliability of the movement of the detection rod 3, thereby ensuring the stable operation of the whole anti-jumping protection device.
