Abstract

The utility model discloses a fastening device for a steel cable for a sugar refinery to lift and stack sugarcanes. The fastening device for the steel cable is characterized in that one side surface of a machine frame is provided with a movable side plate connecting mechanism and a couple of eccentric mechanisms playing the function of automatically and manually locking a steel cable. When the steel cable enters into or be pulled out of a pulley, the steel cable can enter into or be pulled out of the side plate of the pulley by an operating handle making the movable side plate 'opened' or 'closed'; when the steel cable enter inside the pulley, the movable side plate can be 'closed' by the operating handle; a fixed whole body thereby. When the locking steel cable bundles sugarcanes, a self-locking mechanism enables an eccentric wheel automatically to rotate beyond a position, and under the eccentric action, the automatic locking action is played. By the manual locking mechanism enabling the eccentric wheel to manually rotate beyond a position, and under the eccentric action, the manual locking action is played.

Description

Fastening device for steel cable

The utility model relates on the lifting sugarcane, the novel pulley gear when particularly stacking sugarcane in the sugarcane field.

The sugarcane wire rope pulley that hangs that uses at present all is to be made of a rotation liquid wheel and a ring seal framework, in use has following defective:

1. because pulley structure is closed, when steel rope is gone into roller, be to enter in the mode of wearing, cause operator's operating difficulties degree bigger like this, particularly after the steel rope distortion, the operating difficulties degree is just bigger.

2. because steel rope is to enter pulley in the mode of wearing, the pulley mechanism size just must be done greatlyyer, cause sugarcane in lifting, steel rope tends to partially on roller one end or the other end, make pulley mechanism be subjected to force unbalance, and produce the stuck rotation roller of distortion, cause the steel rope hard grind and damage.

3. owing to assist pinch roller, in the lifting sugarcane, steel rope very easily skids off roller groove, and is stuck between framework, causes steel rope abrasion, breaks.

4. owing to do not have binding device, sugarcane to carry out the sugarcane field when stacking, the sugarcane bundle tends to get loose voluntarily, causes that sugarcane is a large amount of loosely to fall down the sugarcane field, and has increased the weight of sugarcane field work capacity.

Some sugar refinery adopts the above-mentioned defective of pulley of energy self-locking to make moderate progress, but because this pulley is confined to use chain, can not use steel rope, causes in application to be restricted.

The purpose of this utility model is exactly that a kind of novel wire rope pulley latching device that can overcome above-mentioned defective will be provided.

The purpose of this utility model is achieved in that in pulley frame one side and is set to " to open " and the movable other plate connection mode mechanism of " pass ", controls it by handle and " open " or " pass ".Can make steel rope enter or deviate from, and reach the effect of lightening one's labor from pulley flanks.Respectively be fixed with an eccentric wheel at the two ends of roller shaft, in the time will binding sugarcane, make eccentric wheel turn over a position by the automatic or manual catch gear, under its accentric effect, the drive roller between eccentric pinch roller, promptly works the sugarcane effect that binds to Steel wire rope lock.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the section-drawing of the utility model device, is drilled with two holes in this device roller (1), and lock pin (4), spring (3) are housed in the hole.Ratchet (6) one end faces are taken turns (1) for often to engage by lock pin (4), spring (3) with liquid, one end face fuses by lock pin and the eccentric wheel (7) that is contained in the inside, frame (8) hole, and eccentric change (7) are welded into one by electric welding and axle (12), eccentric wheel (11), handle (A).Eccentric pinch roller (9) fuses by screw and the eccentric wheel (10), (14) that are contained in the inside, frame (8) hole, and eccentric wheel (10), handle (B) are welded into one by electric welding and axle (13) again.Eccentric wheel (11) is equipped with in movable other plate (2) one stomidiums the inside, the other end is processed with an open recess and a boss, controlling it by handle (B) " opens " or " pass ", roller (1) surface working has the friction line, and eccentric pinch roller (9) driving surface also is processed with a bigger friction rill.

Figure 2 shows that the starting position, steel rope (15) enters pulley from other plate (2) one sides of sliding.

After steel rope enters pulley, as shown in Figure 3, pull handle (A) and rotate counterclockwise, one side drives eccentric wheel (7) and (11) rotated counterclockwise a position, under its accentric effect, roller (1) is moved to left by axle (12); Handle (A) contacts by going up the wire nail that protrudes with movable other plate (2) on the other hand, the other plate of drive activity (2) upwards rotated counterclockwise a position, breach above making movable other plate (2) and axle (13) are to timing, and roller (1) also moves left to the initial position.

Pull another handle (B) again and rotate counterclockwise, as shown in Figure 4, driving eccentric pinch roller (9) turns over a position as conter clockwise on the one hand, under its accentric effect, steel rope is controlled in roller (1) groove; Drive eccentric wheel (10) and (14) on the other hand and also turn over a position, under its accentric effect, axle (13) is moved to right and be embedded in the groove of movable other plate (2), when rotation made eccentric pinch roller (9) reach the maximum eccentric position, axle (13) also was shifted to the right in the groove that is embedded into movable other plate (2) fully.Handle this moment (B) collude mouth also just in time embedding live the boss that movable other plate (2) protrudes, make it fixing movable other plate (2) on the one hand, eccentric pinch roller (9) is fixed on the position of this moment.Operate the pulley working process before promptly finishing the sugarcane lifting.

Sugarcane is in the lifting process, shown in Figure 5, roller (1) rotates around axle (13), ratchet (6) under the friction force effect that steel rope (15) rises, after steel rope (15) binds sugarcane, relative slippage stops between steel rope (15) and the roller (1), and roller (1) stops operating and continues lifting under the situation that sugarcane bound by steel rope.

Automatic encircling process, as shown in Figure 6, when sugarcane is put down the sugarcane field when stacking, steel rope (15) is under the effect of the tensile force of sugarcane self gravitation and sugarcane bundle, be close to roller (1) slippage that faces down, and the generation friction force, under the effect of friction force, roller (1) is turned moving, and the spring (3) by the inside, lock pin (4) rotates ratchet (6) thereupon together, because ratchet (6) connects together with eccentric wheel (7) again, eccentric (7) and eccentric wheel (11) fuse with axle (12) again.So eccentric wheel (7) and (11) are also rotated by band.After turning over a position, under its accentric effect, forcing axle (12) to drive roller (1) moves right together, and steel rope (15) automatic lock is stayed between roller (1) and the eccentric pinch roller (9), and exempted to get loose when sugarcane is bundled in the stacking of sugarcane field, play binding the sugarcane effect automatically.

The manual locking working process, as shown in Figure 7, pull handle (A) drive eccentric wheel (11) and (7) and turn over a position as cw, under its accentric effect, making axle (12) drive roller (1) moves right, and steel rope (15) is locked between roller (1) and the eccentric pinch roller (9), do not cause the sugarcane bundle to get loose, promptly finish the manual locking process.

The pine pulley takes off the sugarcane working process, as shown in Figure 8, pull handle (B) and clockwise rotate, drive eccentric pinch roller (9) by clockwise rotating on the one hand, under its accentric effect, eccentric pinch roller (9) is broken away from compress steel rope (15) position; Drive eccentric wheel (10) and (14) on the other hand and also turn over a position, under its accentric effect, axle (13) is moved to left by cw.When handle (B) has just rotated 180 when spending, axle (13) just fully left side be moved out to the groove gap position of movable other plate (2), movable other plate (2) takes off.Eccentric pinch roller (9) also by the wire nail that protrudes contact with frame (8) (Fig. 8 does not draw) fix on this position, get back to position when beginning, promptly finish loose pulley and take off the sugarcane working process.

The utility model is compared with traditional pulley, has following advantages:

1. the pulley mechanism size is little, and is in light weight, operates light reliable.

2. because the pulley mechanism form is a movable other plate mechanism, go into the pulley mode, make mode, change into to put and make mode, improved the operating difficulties degree from pulley flanks by wearing originally thereby changed traditional steel rope.

3. because pulley is provided with eccentric pinch roller, in the sugarcane lifting, can be controlled at steel rope in the roller groove effectively by eccentric pinch roller, prevent that steel rope from skidding off roller groove and stuck by frame, this defective is broken in wearing and tearing.

4. because pulley is provided with automatically, manual cinching mechanism, when sugarcane is stacked, automatic cinching mechanism, the tensile force that can utilize the self gravitation of sugarcane and sugarcane bundle is as power, automatically steel rope is locked between roller and eccentric pinch roller, thereby prevent that the sugarcane bundle from getting loose.Manually cinching mechanism is to turn over the 0-180 degree by pulling handle, just can be steel rope locking between roller and off-centre.Thereby owing to avoided the loose sugarcane field of falling down of sugarcane by this cinching mechanism.
