Description

TECHNICAL FIELD

[0002] The cable guiding structure for a ship loader is an important mechanical device, which is mainly used for guiding and protecting the cable used by the ship loader during operation. The existing cable guiding structure for a ship loader is composed of an existing magnetic hysteresis cable reel and a drag chain. The magnetic hysteresis cable reel is responsible for automatically winding and unwinding the cable, and the drag chain is responsible for dynamically guiding the cable. However, when the cantilever changes the angle through the luffing device, the cantilever luffing makes an arc motion around the fixed fulcrum. The length of the cable does not match the path length after the cantilever luffing, which causes friction between the cable connected to the cantilever and the cantilever. This will cause the cable to wear out and reduce its service life.

[0003] For example, the "ship loader and cable guiding structure" disclosed in Chinese invention patent (application number: 202110621594.8) has the following disclosure in the specification: the ship loader is a large-scale bulk material mechanical device used for loading bulk material at the bulk material wharf. Generally, the ship loader is composed of a cantilever, a traveling device, a portal, a tower, a luffing device, a slewing device, etc. When the cantilever changes the angle through the luffing device, the cable connected to the cantilever will produce friction with the cantilever, which will cause the outer layer of the cable to wear out and affect the safe operation of the ship loader.

[0036] The cable guiding structure for ship loader provided by the present application solves the problem in the prior art that when the ship loader cantilever changes the angle through the luffing device, the cable on the cantilever will generate friction with the cantilever, which will cause the cable to wear and reduce the service life of the cable, by setting the synchronous adjusting mechanism 2, the synchronous adjusting mechanism 2 is used to adaptively retract and extend the cable, to prevent the situation that the length of the cable does not match the path length after the luffing of the cantilever, thereby improving the service life of the cable.

[0040] It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0041] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0042] Embodiment 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The cable guiding structure for the ship loader is shown, the triangular block 207 and the wedge-shaped block 205 are matched, and the worm wheel 208 and the worm 210 are matched with each other;

[0043] In use, when the machine body 1 is lifted, the cable wound on the winding drum 102 is stretched and drives the winding drum 102 to rotate, as shown in Figure 2 The winding drum 102 rotates clockwise and drives the triangular block 207 to rotate synchronously, the triangular block 207 rotates clockwise and presses the wedge-shaped block 205, because the worm 210 has a self-locking function on the worm wheel 208, so the connecting shaft 201, the sliding seat 202, the transmission block 203 and the wedge-shaped block 205 cannot rotate, and then the wedge-shaped block 205 is pressed by the triangular block 207 and slides in the cavity 204, when the triangular block 207 passes the wedge-shaped block 205, the wedge-shaped block 205 is reset by the elasticity of the spring 206, so that when the machine body 1 is lifted, the winding drum 102 can timely release the cable, when the machine body 1 is lowered, the cable is lowered, and the motor 209 is started, the motor 209 drives the worm 210 to rotate, as shown in Figure 2As shown, the worm 210 drives the worm gear 208 to rotate counterclockwise, the worm gear 208 drives the connecting shaft 201, the sliding seat 202, the transmission block 203 and the wedge block 205 to rotate counterclockwise synchronously, the top of the wedge block 205 drives the triangular block 207 to rotate synchronously with the drum 102, when the cable on the drum 102 is wound and tightened, the wedge block 205 is pressed against the triangular block 207, the wedge block 205 is pressed and slides along the cavity 204, at this time the drum 102 does not rotate, the wedge block 205 idles along the inner wall of the drum 102, in this way, the winding of the cable is realized and the tightness of the cable is adaptively controlled, so that the cable always maintains appropriate tightness during movement, avoiding collision or friction between the cable and other parts of the machine body 1, through adaptive winding and unwinding of the cable, the situation that the length of the cable does not match the path length after the cantilever pitches is prevented, and the service life of the cable is improved;

[0044] Further, the wedge block 205 is provided with a driving shaft 211 rotating thereon, and the driving shaft 211 is provided with a roller 212 which is matched with the drum 102;

[0045] The roller 212 rolls along the inner wall of the drum 102, and through the contact between the roller 212 and the triangular block 207, the friction between the triangular block 207 and the wedge block 205 is reduced, when the triangular block 207 drives the wedge block 205 to slide along the cavity 204, the wedge block 205 is driven by the elasticity of the spring 206 to slide back and hit the inner wall of the drum 102, so that vibration is generated in the drum 102, when the cable is released, the possibility of winding and knotting of the cable is reduced through the vibration, thereby improving the efficiency of the cable release;

[0046] Further, the connecting shaft 201 is provided with a sliding groove 213, and the sliding groove 213 is provided with a bearing 214;

[0047] One end of the cable is connected with the external equipment of the cantilever, and the other end of the cable passes through the bearing 214 and the sliding groove 213 and is connected with the junction box of the machine body 1, in this way, the one end of the cable is not affected when winding and unwinding;

[0048] Through the adaptive winding and unwinding of the cable by the synchronous adjusting mechanism 2, the situation that the length of the cable does not match the path length after the cantilever pitches is prevented, and the service life of the cable is improved, when the cable is released, the possibility of winding and knotting of the cable is reduced through the vibration, thereby improving the efficiency of the cable release.

[0049] In embodiment 2, the cable guiding structure for ship loader provided in embodiment 1 is further optimized, specifically, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, a guide groove 215 is provided on the connecting shaft 201, the sliding seat 202 is slidably disposed on the guide groove 215, and a drive block 216 is provided on the drum 102, the drive block 216 and the wedge block 205 are adapted to each other.

[0050] like Figure 6 As shown, one end of the drive block 216 that contacts the wedge block 205 is wedge-shaped. When the transmission block 203 rotates, the drive block 216 blocks the transmission block 203. When the sliding seat 202 is driven to slide along the guide groove 215, causing the wedge block 205 to disengage from the triangular block 207 and contact the drive block 216, in the case of cable winding, as... Figure 3 As shown, when the sliding seat 202, transmission block 203 and wedge block 205 are driven to rotate counterclockwise, the transmission block 203 pushes the drive block 216, and the drive block 216 drives the drum 102 to rotate synchronously, thereby realizing the winding of the cable. This method is suitable for situations where the cable gets stuck during the winding process.

[0051] Furthermore, a push block 217 is slidably disposed inside the cavity 204, and a threaded rod 218 is rotatably disposed on the sliding seat 202 and the transmission block 203. The push block 217 and the threaded rod 218 are connected by threads, and the two ends of the spring 206 are respectively disposed on the corresponding surfaces of the push block 217 and the cavity 204.

[0052] When the threaded rod 218 is rotated, the threaded rod 218 rotates and drives the jacking block 217 to slide along the cavity 204. The jacking block 217 slides and squeezes the spring 206, which increases the elastic potential energy of the spring 206. For cables of different sizes, by changing the elastic potential energy of the spring 206, the adaptive winding and unwinding of cables of different sizes can be achieved.

[0053] Furthermore, a drive gear 219 is provided on the threaded rod 218, and a gear disk 220 is rotatably provided on the sliding seat 202. The gear disk 220 and the drive gear 219 are matched, and a drive ring 221 is provided on the gear disk 220.

[0054] When the drive ring 221 is rotated, the drive ring 221 drives the gear disk 220 to rotate synchronously, the gear disk 220 drives the drive gear 219 to rotate synchronously, and the drive gear 219 drives the threaded rod 218 to rotate synchronously. Figure 5 As shown

[0055] Furthermore, a rubber pad 222 is provided on the sliding groove 213. The sliding seat 202 and the rubber pad 222 are adapted to each other. The rubber pad 222 increases the friction between the sliding seat 202 and the sliding groove 213, preventing the sliding seat 202 from sliding on the sliding groove 213 when the roller 212 hits the inner wall of the drum 102.

[0056] When the cable of different sizes is reeled and unreeled, the elastic potential energy of the spring 206 is adjusted to realize the self-adaptive reeling and unreeeling of the cable of different sizes, and the versatility of the equipment is improved.

[0057] The use process of the cable guiding structure for the ship loader provided by the application is as follows:

[0058] When the machine body 1 is lifted, the cable wound on the reel 102 is stretched and drives the reel 102 to rotate, the reel 102 rotates clockwise and synchronously drives the triangular block 207 to rotate, at this time, the reel 102 rotates clockwise and releases the cable, the triangular block 207 rotates clockwise and presses the wedge-shaped block 205, the wedge-shaped block 205 is pressed by the triangular block 207 and slides in the cavity 204, at this time, the roller 212 rolls along the inner wall of the reel 102, when the triangular block 207 passes the wedge-shaped block 205, the wedge-shaped block 205 and the roller 212 are synchronously reset and hit the inner wall of the reel 102 by the elasticity of the spring 206, so that vibration is generated in the reel 102, which reduces the possibility of cable winding and knotting, so that the reel 102 can timely release the cable when the machine body 1 is lifted, when the machine body 1 is lowered, the cable is lowered, the motor 209 is started, the motor 209 drives the worm 210 to rotate, the worm 210 drives the worm wheel 208 to rotate counterclockwise, the worm wheel 208 drives the connecting shaft 201, the sliding seat 202, the transmission block 203 and the wedge-shaped block 205 to synchronously rotate counterclockwise, the triangular block 207 is driven by the wedge-shaped block 205, so that the triangular block 207 and the reel 102 synchronously rotate, when the cable on the reel 102 is wound and tight, at this time, the wedge-shaped block 205 presses the triangular block 207, the wedge-shaped block 205 is pressed and slides along the cavity 204, at this time, the reel 102 does not rotate, the wedge-shaped block 205 idles along the inner wall of the reel 102, in this way, the winding of the cable is realized and the tightness of the cable is adaptively controlled, so that the cable always maintains appropriate tightness during movement, by rotating the driving ring 221, the driving ring 221 drives the toothed disc 220 to synchronously rotate, the toothed disc 220 drives the driving gear 219 to synchronously rotate, the driving gear 219 drives the threaded rod 218 to synchronously rotate, the threaded rod 218 rotates and drives the jacking block 217 to slide along the cavity 204, the jacking block 217 slides and presses the spring 206, so that the elastic potential energy of the spring 206 is increased, for the cable of different sizes, the elastic potential energy of the spring 206 is changed to realize the self-adaptive reeling and unreeeling of the cable of different sizes.
