Abstract
The utility model discloses an anti-rope-breaking device for a portal frame, belonging to the technical field of safety protective devices of gantries. A steel wire rope passes through the space between a spring and two compression blocks after being wound through a pulley; an insertion block is arranged between the spring and the compression blocks, and is used for fixing a compressed spring; a pulley support frame is used for fixing the pulley on a frame box, and is connected with a pressure sensing box; one end of the insertion block is connected with the pressure sensing box through a thin steel wire rope; the other end of the insertion block is connected with one end of a three-arm lever after being wound through two wire guide wheels; the three-arm lever can rotate around a lever shaft; the other end of the three-arm lever is connected with a clamping block; the clamping block is arranged between a fixed friction block and a movable friction block; and the movable friction block is connected with a strong spring, and can move along a slide rail between the movable friction block and the fixed friction block. The anti-rope-breaking device has a relatively simple structure, and reacts sensitively; and due to the adoption of dual anti-rope-breaking protective device, the protection effects on operating personnel and equipment is enhanced.
Description
Technical field
The utility model relates to portal frame and uses the anti-break rope device, belongs to the safety device technical field of lifting portal frame.
Background technology
In present building field; In order to prevent that the portal frame steel rope from rupturing suddenly; Cause hanging the hurdle and fall and grave accident takes place, usually the anti-break rope safety guard will be installed on the portal frame, existing fender guard exist install inconvenient; Safety factor is little or react shortcoming such as insensitive, makes operating personnel's personal safety face hidden danger.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model provide a kind of easy for installation, be quick on the draw, the portal frame of duplicate protection uses the anti-break rope device.
For realizing above-mentioned purpose, the utility model solves through following technical scheme: portal frame is used the anti-break rope device, comprises steel rope, pulley; The pulley support frame is characterized in that also comprising pressure sensitive case, spring, inserted block; Two compact heaps, guide roller, three arm bars, lever shaft; Slide rail, the fixed friction piece, fixture block moves friction shoe; Brute spring and frame case constitute, and steel rope is walked around and passed behind the pulley between spring and two compact heaps, and inserted block is used for fixing compressed spring between spring and compact heap, and the pulley support frame is fixed on pulley on the frame case; Connect the pressure sensitive case, a section of inserted block connects the pressure sensitive case with seizing wire, and the other end is walked around two guide rollers and is connected with an end of three arm bars, and three arm bars can rotate around lever shaft; The other end of three arm bars connects fixture block, and fixture block moves friction shoe and is connected with brute spring between fixed friction piece and mobile friction shoe, can the edge and the fixed friction piece between slide rail move.
The utility model is characterised in that when wire cable rupture; Pressure on the pulley reduces suddenly, is reflected on the pressure inductor, then spurs seizing wire; Inserted block is detached between spring and the compact heap; Originally compressed spring is squeezed in steel rope between two compact heaps because elastic force pushes two compact heaps then, has prevented to hang falling of hurdle; Simultaneously; Seizing wire spurs three arm bars and rotates; Fixture block is released between fixed friction piece and the mobile friction shoe; Slide rail moves to the fixed friction piece in the elastic force effect lower edge of brute spring to move friction shoe, and then the fixed friction piece contacts with the portal frame track with mobile friction shoe and rubs, and has effectively prevented and has hung falling of hurdle.
The structure of the utility model is simple relatively, and is quick on the draw, and dual anti-break rope fender guard has increased the protective effect to operating personnel and equipment.
Description of drawings
Fig. 1 for portal frame with anti-break rope apparatus structure sketch.
Among the figure: 1, steel rope, 2, pulley, 3, the pulley support frame, 4, the pressure sensitive case; 5, spring, 6, inserted block, 7, compact heap, 8, guide roller; 9, three arm bars, 10, lever shaft, 11, slide rail, 12, the fixed friction piece; 13, fixture block, 14, move friction shoe, 15, brute spring, 16, the frame case.
The specific embodiment
Portal frame shown in Figure 1 is used the anti-break rope device; Comprise steel rope 1, pulley 2, pulley support frame 3, be characterised in that and also comprise pressure sensitive case 4, spring 5, inserted block 6, two compact heaps 7, guide roller 8, three arm bars 9, lever shaft 10, slide rail 11, fixed friction piece 12, fixture block 13, move friction shoe 14, brute spring 15, frame case 16; Steel rope 1 is walked around and is passed behind the pulley 2 between spring 5 and two compact heaps 7, and inserted block 6 is used for fixing compressed spring 5 between spring 5 and compact heap 7, and pulley support frame 3 is fixed on pulley 2 on the frame case 16; Connect pressure sensitive case 4; One end of inserted block 6 connects pressure sensitive case 4 with seizing wire, and the other end is walked around two guide rollers 8 and is connected with an end of three arm bars 9, and three arm bars 9 can be around lever shaft 10 rotations; The other end of three arm bars 9 connects fixture block 13; Fixture block 13 moves friction shoe 14 and is connected with brute spring 15 between fixed friction piece 12 and mobile friction shoe 14, can the edge and fixed friction piece 12 between slide rail 11 move.
The utility model is characterised in that when steel rope 1 fracture; Pressure on the pulley 2 reduces suddenly, is reflected on the pressure inductor 4, then spurs seizing wire; Inserted block 6 is detached between spring 5 and the compact heap 7; Originally compressed spring 5 has prevented to hang falling of hurdle because elastic force with 7 extruding of two compact heaps, is squeezed in steel rope 1 between two compact heaps 7 then; Simultaneously; Seizing wire spurs three arm bars 9 and rotates; Fixture block 13 is released between fixed friction piece 12 and the mobile friction shoe 14; Slide rail 11 moves to fixed friction piece 12 in the elastic force effect lower edge of brute spring 15 to move friction shoe 14, and then fixed friction piece 12 contacts with the portal frame track with mobile friction shoe 14 and rubs, and has effectively prevented and has hung falling of hurdle.
