Detailed Description
In order that the above objects, features and advantages of the invention will be more clearly understood, a further description of the invention will be made. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the invention.
As shown in fig. 1 and 2, the present invention provides a moving device (hereinafter referred to as moving device) of a cable crane, which includes a beam 1, a power device, a plurality of movable connection devices 25, and a plurality of traveling devices. The movable connecting device 25 is arranged on the beam body 1, and the movable connecting device 25 is used for being movably connected with the cable 23. The walking device is arranged on the beam body 1 and is used for moving on the cable 23; the walking device is arranged in a telescopic structure so as to adjust the distance between the beam body 1 and the cable 23; a power device is connected to the beam body 1, and the power device is used for driving the beam body 1 to move along the extending direction of the cable 23.
The power device can provide power for the beam body 1, so that the beam body 1 can move along the cable 23 through the running gear. When running gear and articulating mechanism 25 are advanced across the locking clamp 24, all running gear are extended toward cable 23 so that articulating mechanism 25 is raised with beam 1, the first running gear is retracted toward beam 1 (in the direction of advance of beam 1) so that the first running gear is above the locking clamp 24 and can ride across the locking clamp 24, and the power mechanism drives beam 1 to move the first running gear across the locking clamp 24, and then the first running gear is moved toward cable 23 until it contacts cable 23. The following running gear may then follow this process sequentially across the locking clip 24. When all running gear and articulating mechanism 25 are straddled the locking clips 24, the power mechanism can continue to drive the beam 1 to move to the target position. When the beam 1 is moved to the target position, all running gear is retracted so that the articulating mechanism 25 is lowered with the beam 1, and then the articulating mechanism 25 is fixedly attached to the cable 23 so that the beam 1 is secured to the cable 23. So through the cooperation of running gear and power device, roof beam body 1 and swing joint device 25 can easily stride across lock clamp 24, have improved mobile device's work efficiency.
In the present invention, a plurality means two or more. The beam 1, the power unit, the movable connection unit 25 and the running gear may be all common devices in the art, and the present invention is not limited thereto.
Further, the running gear includes pneumatic cylinder 2 and walking wheel 3, and the cylinder and the roof beam body 1 of pneumatic cylinder 2 are connected, and walking wheel 3 is connected with the flexible end of pneumatic cylinder 2, and walking wheel 3 is used for removing on cable 23.
The hydraulic cylinder 2 includes a cylinder body and a retraction rod 22, and the retraction rod 22 can be extended from the cylinder body or retracted into the cylinder body. The free end of the retraction lever 22 (i.e., the end of the retraction lever remote from the cylinder) is the retraction end. Preferably, the hydraulic cylinder 2 is provided in the beam 1. The traveling wheel 3 comprises a traveling wheel frame and a traveling wheel body, and the traveling wheel body is connected with the traveling wheel frame through a shaft. The telescopic end of the hydraulic cylinder 2 is connected with a travelling wheel frame. The hydraulic cylinder 2 and the road wheel 3 are common devices in the art, and the present invention will not be described in further detail.
In this embodiment, when the telescopic end of the hydraulic cylinder 2 is extended, the traveling wheel 3 is pushed down by the hydraulic cylinder 2, but the traveling wheel 3 is blocked by the cable 23, the telescopic end of the hydraulic cylinder 2 cannot be extended downward, and the cylinder body of the hydraulic cylinder 2 is raised, so that the beam body 1 connected to the cylinder body is raised, and the interval between the beam body 1 and the cable 23 is increased. Meanwhile, the height of the movable connecting device 25 is increased along with the beam body 1, so that a space can be generated between the movable connecting device 25 and the locking clamp 24. The telescopic end of the first hydraulic cylinder 2 (i.e. the hydraulic cylinder 2 closest to the locking clamp 24) is then retracted and the road wheel 3 on the first hydraulic cylinder 2 is moved towards the beam 1 until the road wheel 3 is above the locking clamp 24 and can cross the locking clamp 24. Then the power device drives the beam body 1 to move, when the travelling wheel 3 on the first hydraulic cylinder 2 crosses the locking clamp 24, the power device stops driving, and the telescopic end of the first hydraulic cylinder 2 stretches, so that the travelling wheel 3 on the first hydraulic cylinder 2 is attached to the cable 23 again. The road wheel 3 on the second hydraulic cylinder 2 is then moved towards the beam 1 until the road wheel 3 is above the locking clamp 24 and can cross the locking clamp 24, the power means driving the beam 1 to move. The remaining hydraulic cylinders 2 perform the above-described actions in sequence. When all the travelling wheels 3 and all the movable connecting devices 25 cross the locking clamps 24, the telescopic ends of all the hydraulic cylinders 2 retract, the cylinders of the hydraulic cylinders 2 descend, the beam body 1 descends, and the distance between the beam body 1 and the cable 23 is reduced. At the same time, the height of the movable connecting device 25 is reduced along with the beam body 1, and the movable connecting device 25 can be connected on the cable 23 again.
Further, the outer edge of the travelling wheel 3 is configured to conform to the curved shape of the cable 23.
Specifically, the outer edge of the travelling wheel 3 is curved, so that the outer edge of the travelling wheel 3 can be attached to the surface of the cable 23. On one hand, the contact area between the travelling wheel 3 and the cable 23 can be increased, and on the other hand, the stability of the travelling wheel 3 during movement can be improved, so that the travelling wheel 3 is safer during movement.
Further, the articulating mechanism 25 is arranged to be movable along the beam 1.
The position of the movable connecting device 25 on the beam body 1 can be adjusted according to different working conditions. For example, when the power means stops driving the movement of the beam 1, or at a target position of the beam 1, the articulating means 25 may just correspond to the mounting position of the locking clip 24. The articulating mechanism 25 can only be attached to the locking clip 24 at this time, which can make it difficult to secure the beam 1 to the cable 23. The articulating mechanism 25 may be moved a distance along the beam 1 such that the articulating mechanism 25 may avoid the location of the locking clip 24 and connect with the cable 23 to help secure the beam 1 to the cable 23. Of course, if the articulating mechanism 25 does not require adjustment of position, the articulating mechanism 25 may still remain in place.
The movable connection means 25 can be moved along the beam 1 in various configurations. For example, the bottom side of the beam body 1 is provided with a connecting plate extending along the length direction of the beam body 1, a plurality of threaded holes distributed along the length direction of the beam body 1 are penetrated on the connecting plate, the movable connecting device 25 is connected with part of the threaded holes through bolts, and when the position of the movable connecting device 25 needs to be adjusted, the movable connecting device 25 is replaced in installation position and connected with the corresponding threaded holes. Of course, the present invention is not limited to the above-described embodiments.
Further, as shown in fig. 3, the beam body 1 includes a beam body 4 and a beam bottom plate 5, the beam bottom plate 5 is attached to the bottom side of the beam body 4, and the beam bottom plate 5 extends along the length direction of the beam body 4. Two clamping blocks 6 are fixedly connected to the top side of the movable connecting device 25, and the beam body 4 is located between the two clamping blocks 6. One side of the clamping block 6 facing the beam body 4 is provided with a sliding groove 7, and two sides of the beam bottom plate 5 are respectively inserted into the two sliding grooves 7 correspondingly. The clamping block 6 is internally provided with a limit bolt 8 which can be used for limiting the movable connecting device 25 to move along the beam body 1.
Both sides of the beam bottom plate 5 protrude from the beam body 4, i.e., the width of the beam bottom plate 5 is greater than the width of the beam body 4, so that the cross section of the lower portion of the beam body 1 is substantially inverted T-shaped. Two sides of the beam bottom plate 5 are respectively inserted into the two clamping blocks 6, so the beam bottom plate 5 can be used as a sliding rail of the running gear. The clamping block 6 is provided with a threaded hole communicated with the sliding groove 7, the limit bolt 8 is installed in the threaded hole, the top end of the limit bolt 8 extends out of the threaded hole (the limit bolt 8 is convenient to rotate), and the bottom end of the limit bolt 8 extends out of the threaded hole and can be in contact with the beam bottom plate 5. The threaded holes may be vertically extending, horizontally extending, or obliquely extending, and the present invention is not limited thereto. Of course, a plurality of limit bolts 8 may be disposed in the clip 6, and all of the limit bolts 8 are preferably distributed at intervals along the length direction of the beam bottom plate 5.
In this embodiment, when the position of the movable connecting device 25 needs to be adjusted, the limit bolt 8 is rotated, so that the bottom end of the limit bolt 8 is far away from the beam bottom plate 5, and the beam bottom plate 5 is movably connected with the clamping block 6, so that the movable connecting device 25 can be pushed to move along the beam bottom plate 5. When the movable connecting device 25 moves to a proper position, the limit bolt 8 is rotated, so that the bottom end of the limit bolt 8 is pressed on the beam bottom plate 5, and no relative movement is generated between the beam bottom plate 5 and the clamping block 6, so that the movable connecting device 25 and the beam bottom plate 5 are fixed.
Further, as shown in fig. 4, a pad 9 is disposed in the chute 7, the pad 9 is located above the beam bottom plate 5, and a groove is disposed at the top of the pad 9. The limit bolt 8 is mounted at the top of the clamping block 6, the bottom end of the limit bolt 8 can be circumferentially and rotatably mounted in the groove, the base plate 9 is further provided with a limit piece 10, and the limit piece 10 is used for limiting the bottom end of the limit bolt 8 in the groove.
The screw hole sets up at the top of fixture block 6, and limit bolt 8 installs at the top of fixture block 6 promptly. The top end of the limit bolt 8 extends out of the threaded hole, and the bottom end of the limit bolt 8 extends out of the threaded hole and is accommodated in a groove at the top of the backing plate 9. The diameter of the bottom end of the limit bolt 8 is larger than the diameter of the middle section of the limit bolt 8, and the bottom end of the limit bolt 8 is always positioned in the groove under the limit of the limit piece 10. For example, the limiting member 10 is a limiting plate provided with a through hole, the limiting plate is mounted on the top side of the backing plate 9 and covers the groove, the diameter of the bottom end of the limiting bolt 8 is larger than that of the through hole, the middle section of the limiting bolt 8 passes through the through hole, and the bottom end of the limiting bolt 8 is limited in the groove by the limiting plate. And the bottom end of the limit bolt 8 and the backing plate 9 are not fixedly connected, and the backing plate 9 only moves upwards or downwards but does not rotate circumferentially during circumferential rotation of unscrewing or screwing of the limit bolt 8.
In this embodiment, when the position of the movable connection device 25 needs to be adjusted, the limit bolt 8 is unscrewed, so that the limit bolt 8 leaves the top surface of the beam bottom plate 5, and the beam bottom plate 5 is movably connected with the clamping block 6, so that the movable connection device 25 can be pushed to move along the beam bottom plate 5. When the movable connecting device 25 moves to a proper position, the limit bolts 8 are screwed, so that the base plate 9 is pressed on the beam bottom plate 5, and no relative movement is generated between the beam bottom plate 5 and the clamping blocks 6, so that the movable connecting device 25 and the beam bottom plate 5 are fixed.
In addition, the stopper 10 may have other structures, and the present invention is not limited thereto. For example, the stopper 10 is a plate member, and the side portion of the stopper 10 is provided with a groove recessed from the edge toward the center, and the stopper bolt 8 may be inserted in the groove. For another example, the stopper 10 is a U-shaped rod or a rectangular frame.
Further, as shown in fig. 3, the beam body 1 includes a beam body 4 and a beam bottom plate 5, the beam bottom plate 5 is connected to the bottom side of the beam body 4, and the beam bottom plate 5 extends along the length direction of the beam body 4. Two rollers are arranged above the movable connecting device 25, and the beam body 4 is positioned between the two rollers. The gyro wheel includes gyro wheel body 11 and gyro wheel link 12, and gyro wheel link 12 installs the topside at swing joint 25, and gyro wheel body 11 and gyro wheel link 12 hub connection, and gyro wheel body 11 can follow beam bottom plate 5's topside and remove.
Both sides of the beam bottom plate 5 protrude from the beam body 4, i.e., the width of the beam bottom plate 5 is greater than the width of the beam body 4, so that the cross section of the lower portion of the beam body 1 is substantially inverted T-shaped. The roller wheel frame can be a common wheel frame in the field, and a person skilled in the art can flexibly set the roller wheel frame according to the needs, so that the invention is not limited. Preferably, the roller frame comprises a top plate and a pair of support plates which are distributed oppositely and extend vertically, the bottom ends of the two support plates are arranged on the top side of the movable connecting device 25, and the top ends of the two support plates are connected through the top plate. The lower side of the top plate is also provided with a pair of shaft connecting plates at intervals, and the idler wheel body 11 is positioned between the two shaft connecting plates and is in shaft connection with the two shaft connecting plates. The roller frame can support the roller body 11 to a certain height, so that the roller body 11 and the top side of the movable connecting device 25 have a certain distance, and the distance is not smaller than the thickness of the beam bottom plate 5, so that the beam bottom plate 5 can be arranged between the roller body 11 and the movable connecting device 25.
In this embodiment, when the movable connecting device 25 moves along the beam body 1, the roller body 11 can move against the top side of the beam bottom plate 5, so that the friction between the movable connecting device 25 and the beam body 1 is reduced, and the movable connecting device 25 can move more conveniently.
Preferably, two pairs of rollers are provided above the articulating mechanism 25, the four rollers being distributed at the four corners of the top side of the articulating mechanism 25. And two rollers are distributed on both sides of each clamping block 21 in the length direction of the beam body 4 so that the movable connecting device 25 can stably move. Support tables can be further arranged at four corners of the top of the movable connecting device 25, and each support table is provided with a roller, so that the length of the clamping block 6 is as long as possible, and the connection stability between the movable connecting device 25 and the beam body 1 is ensured.

Specifically, the support bracket 13 includes a support portion and an installation portion, both of which are hollow rectangular parallelepiped housings. Preferably, the support portion and the mounting portion are integrally formed. The support part is installed at the top side of the roller link frame 12, and the installation part is installed at the top side of the roller link frame 12.

A motor 15 is mounted on the top side of the mounting portion, and the motor 15 is connected with the gear 14. The motor 15 can rotate along the rack 16 through the driving gear 14, so that the movable connecting device 25 can move along the length direction of the beam body 1 to adjust the position of the movable connecting device. In addition, in order to reduce the weight of the support frame 13, an opening may be provided on both the side of the support portion facing the beam body 1 and the side facing the roller connecting frame 12, and an opening may be provided on the side of the mounting portion facing away from the beam body 1.
Of course, the support 13 may be a common component in the art, and those skilled in the art may need to select a suitable structure, for example, may be configured in a "Chinese" shape, an L-shape, an F-shape, or the like, and the present invention is not limited thereto.

When the beam 1 reaches the target position, i.e. the beam 1 reaches the position closest to the fixed sheave 18, the fixed sheave 18 can be reinstalled to a higher position in order to pull the beam 1 higher. Of course, the winch 17 may also pay out the wire 19 stepwise to move the beam 1 downwards away from the fixed sheave 18, i.e. the beam 1.
In this embodiment, the steel wire rope 19 is a flexible component, and along with the change of the distance between the beam body 1 and the fixed pulley 18, the posture (such as the inclination angle or the distance between the steel wire rope 19 and the cable 23) of the steel wire rope 19 can be adaptively and dynamically adjusted, so that the stable movement of the beam body 1 is ensured.
In addition, the driving device may be a type of device. For example, the driving means is an electric telescopic rod, one end of the electric telescopic rod 22 is hinged to the front end of the beam body 1, the other end of the electric telescopic rod 22 is hinged to the cable 23, and when the electric telescopic rod 22 is contracted, the beam body 1 is pulled forward.
Further, as shown in fig. 3, the movable connection device 25 includes a base 20 and two clamping blocks 21, the base 20 is connected with the beam body 1, the clamping blocks 21 are hinged with the base 20, and the base 20 and the two clamping blocks 21 can clamp the cable 23 between the three. A telescopic rod is arranged between the clamping block 21 and the base 20, and the telescopic rod can drive the clamping block 21 to clamp or loosen the cable 23.
When the power device drives the beam body 1 to move, the base 20 and the clamping blocks 21 can be properly opened, so that excessive friction force between the movable connecting device 25 and the cable 23 is avoided. When the beam body 1 reaches the target position, the base 20 and the clamp block 21 clamp the cable 23 so that the articulating mechanism 25 is firmly secured to the cable 23. The lifting lever 22 may be a hydraulic lifting lever 22, an electric lifting lever 22, or a manual lifting lever 22, and the present invention is not limited thereto. The base 20 and the clamp block 21 may be plate members or bar members, and the present invention is not limited thereto. The base 20 and the clamp block 21 are preferably C-shaped or arc-shaped plates so that the base 20 and the clamp block 21 can be closely fitted to the cable 23.
Further, as shown in fig. 3, a mounting hole for the cable 23 to pass through is provided between the base 20 and the two clamping blocks 21, and the wall of the mounting hole can be attached to the surface of the cable 23. The telescopic rod is located outside the mounting hole.
The cable 23 can be arranged in the mounting hole in a penetrating way, and the contact area between the cable 23 and the movable connecting device 25 is large, so that the movable connecting device 25 can be firmly fixed on the cable 23. And the lifting and contracting rod 22 is positioned outside the mounting hole, so that interference between the lifting and contracting rod 22 and the cable 23 can be avoided.
The operation of the mobile device will be described with reference to fig. 1 and 2.
Step one, the mobile device is mounted on the cable 23.
At this point, the clamp blocks 21 are fully open, and either clamp block 21 is moved away from the cable 23 to avoid the articulating mechanism 25 from getting stuck at the lock clamp 24. And all running gear are elongated to cable 23, and articulating mechanism 25 is moved away from cable 23 with beam 1. The distance between the beam 1 and the cable 23 is large and the articulating means 25 is higher than the height of the locking clamp 24 and can span the locking clamp 24. The power device drives the beam body 1 to move, and the beam body 1 moves along the cable 23 through the travelling device. Of course, the running gear may be extended again when the running gear approaches the lock clamp 24.
Step two, the articulating mechanism 25 spans the locking clip 24.
When the beam 1 is moved to a position close to the locking clamp 24, the first running gear (in the advancing direction) is retracted toward the beam 1 until the first running gear is higher than the locking clamp 24 and can cross the locking clamp 24, and the power device drives the beam 1 to move until the first running gear crosses the locking clamp 24. The first running gear is then extended toward the cable 23 until the first running gear contacts the cable 23.
The second running gear is then retracted towards the beam 1 until the second running gear is higher than the height of the locking clamp 24 and can ride over the locking clamp 24, and the power unit drives the beam 1 to move until the second running gear rides over the locking clamp 24. The second running gear is then extended toward the cable 23 until the second running gear contacts the cable 23. The following running gear also repeatedly executes the above-mentioned process, and will not be described again. And as each running gear rides over the locking clip 24, the articulating mechanism 25 also rides over the locking clip 24.
When the last running gear and the last articulating mechanism 25 span the locking clamp 24, the last running gear extends toward the cable 23 until it contacts the cable 23. The power plant can then continue to drive the beam 1 towards the target position.
It should be noted that, during the extending or retracting process of each running gear, the power device may be in an operating or stopped state.
Step three, the movable connecting device 25 is fixed with the cable 23.
When the beam 1 is moved to the target position, all running gear is retracted towards the beam 1 so that the distance between the beam 1 and the cable 23 is reduced and the articulating mechanism 25 is close to the cable 23. The articulating mechanism 25 is then fixedly attached to the cable 23 to secure the beam 1 to the cable 23. For example, three clamp blocks 21 are clamped around the cable 23.
However, if the lock clip 24 is present at the target position, there is interference between the articulating mechanism 25 and the lock clip 24, and the position of the articulating mechanism 25 needs to be adjusted. Specifically, after the last running gear and the last movable connecting device 25 cross the locking clamp 24, the position of the movable connecting device 25 is adjusted, so that the movable connecting device 25 moves on the beam body 1 for a certain distance, the movable connecting device is staggered with the locking clamp 24, and then the movable connecting device 25 is fixedly connected with the beam body 1 again. All running gear are then retracted towards the beam body 1, and the articulating mechanism 25 is fixedly connected to the cable 23. At the moment, the cable crane enters a working state, and various devices can be hoisted.
