Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a fixed-distance moving device for a piling platform, a piling platform, a system, and an integrated pile and beam machine. Background Technology

[0002] In bridge erection operations using a pile-beam integrated machine, the piling platform near the front end of the main beam is responsible for piling operations. During piling of pipe piles at different locations, the piling platform also needs to move the pile hammer to the designated position for piling. Specifically, the piling platform includes a transverse platform and a longitudinal platform. The transverse platform moves along the width of the main beam, and the longitudinal platform moves along the length of the main beam. During the movement of the longitudinal platform, a jacking device is usually required to provide driving force. The winch assembly at the rear of the piling platform is connected to the pile hammer via a wire rope. Furthermore, the driving process of the pile hammer is controlled. The steel wire rope applies a backward tension to the longitudinal moving platform, causing the platform to tend to move backward. During the movement of the longitudinal moving platform, the jacking force applied by the jacking device can overcome the tension of the steel wire rope to push the longitudinal moving platform to move. However, after the jacking force is released, how to position the longitudinal moving platform to avoid being pulled backward by the steel wire rope has become an urgent technical problem to be solved. The existing limiting device is difficult to meet the requirement that the longitudinal moving platform releases the limit to move when subjected to the jacking force, and at the same time, it needs to be limited after the jacking force is released to avoid being pulled backward. Utility Model Content

[0003] The purpose of this utility model is to overcome the technical problem that existing piling platforms are difficult to position when subjected to the backward tension of the wire rope of the winch assembly during movement, and to provide a fixed-distance moving device for a piling platform, a piling platform, a system, and an integrated pile and beam machine.

[0004] In a first aspect, the present invention provides a fixed-distance moving device for a piling platform, comprising a driving mechanism and a positioning mechanism installed on the piling platform. The driving mechanism includes a driving cylinder, one end of which is connected to the piling platform, and the other end of which can be connected to a main beam below the piling platform. The positioning mechanism and rollers are provided between the piling platform and the main beam.

[0005] This utility model's piling platform employs a step-by-step fixed-distance movement device. A drive cylinder is installed on one side of the piling platform, pushing it forward to move the platform. A positioning mechanism and rollers are installed between the piling platform and the main beam. The positioning mechanism locks the piling platform onto the main beam after the drive cylinder extends to its maximum stroke, thus fixing the platform relative to the main beam. This ensures stability even when the driving cylinder's pushing force is released and the winch assembly's wire rope tension is applied, preventing it from being pulled backward. After the piling platform is locked by the positioning mechanism, the end of the drive cylinder connected to the main beam is moved, causing the drive cylinder to retract. The drive cylinder is then fixed to the main beam, and the positioning mechanism is released. The drive cylinder is then extended again to push the piling platform forward, achieving step-by-step movement. When the drive cylinder applies a pushing force to the piling platform, the positioning mechanism can be released, allowing relative movement between the piling platform and the main beam. Under this pushing force, the piling platform can move to the designated position on the main beam via the rollers. The positioning mechanism can switch between locked and unlocked states to fix and move the piling platform, thereby overcoming the back tension of the winch assembly wire rope.

[0006] Preferably, the other end of the drive cylinder is connected to the main beam via a locking mechanism, the locking mechanism including a locking cylinder and a connecting frame, the locking cylinder being installed inside the connecting frame.

[0007] Preferably, the positioning mechanism includes a plurality of lifting cylinders disposed at the bottom of the piling platform.

[0008] Preferably, the positioning mechanism includes a lead screw disposed on one side of the main beam and an ear plate disposed at the bottom of the piling platform. The ear plate is sleeved on the lead screw, and positioning nuts are sleeved on both sides of the lead screw located on the ear plate.

[0009] Preferably, the two ends of the lead screw are fixedly connected to the main beam via connecting rods.

[0010] Preferably, the rollers include a main roller located at the top of the main beam and side rollers located on both sides of the main beam.

[0011] In a second aspect, the present invention provides a piling platform, including a transverse platform, a longitudinal platform, and a fixed-distance moving device for the piling platform as described above; the transverse platform is disposed above the longitudinal platform, and the fixed-distance moving device is disposed on the longitudinal platform.

[0012] Preferably, a transverse slide rail is provided between the transverse platform and the longitudinal platform.

[0013] In a third aspect, the present invention provides a piling system, including a pile frame, a pile hammer, and a piling platform as described above, wherein the pile frame is vertically arranged on the piling platform, and the pile hammer is mounted on the pile frame.

[0014] In a fourth aspect, this utility model provides a pile-beam integrated machine, including a main beam and a pile driving system as described above, wherein the pile driving system is installed on the main beam.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a fixed-distance moving device for a piling platform, a piling platform, a system, and an integrated pile-beam machine. It employs a step-type fixed-distance moving device, where a drive cylinder is installed on one side of the piling platform. The drive cylinder pushes the piling platform to move it. Simultaneously, a positioning mechanism and rollers are installed between the piling platform and the main beam. The positioning mechanism locks the piling platform onto the main beam after the drive cylinder extends to its maximum stroke, thus fixing the piling platform relative to the main beam. This ensures that the platform remains fixed even when the pushing force of the drive cylinder is released and the winch assembly wire rope is under tension. To avoid being pulled backward, the piling platform is locked by a positioning mechanism. Then, the end of the drive cylinder connected to the main beam is moved, causing the drive cylinder to retract. Afterward, the drive cylinder is fixed to the main beam, and the positioning mechanism is unlocked. The drive cylinder is then extended to push the piling platform further, achieving step-by-step movement. When the drive cylinder applies a jacking force to the piling platform, the positioning mechanism can be unlocked, allowing relative movement between the piling platform and the main beam. This allows the piling platform to move to the designated position on the main beam via rollers under jacking force. The positioning mechanism can switch between locked and unlocked states to achieve both fixing and movement of the piling platform, thus overcoming the backward pull of the winch assembly's wire rope.

[0030] Example 1 This embodiment provides a fixed-distance moving device for a piling platform.

[0031] like Figures 1 to 7 As shown, the fixed-distance moving device of the piling platform in this embodiment includes a driving mechanism and a positioning mechanism installed on the piling platform. The driving mechanism includes a driving cylinder 1, one end of which is connected to the piling platform, and the other end of which can be connected to the main beam 12 below the piling platform. A positioning mechanism and rollers are provided between the piling platform and the main beam 12.

[0032] This utility model's piling platform employs a step-by-step fixed-distance moving device. A drive cylinder 1 is installed on one side of the piling platform, pushing it forward to achieve movement. Simultaneously, a positioning mechanism and rollers are installed between the piling platform and the main beam 12. The positioning mechanism locks the piling platform onto the main beam 12 after the drive cylinder 1 extends to its maximum stroke, thus fixing the piling platform relative to the main beam 12. This ensures that even when the pushing force of the drive cylinder 1 is released and the platform is subjected to the tension of the winch assembly's wire rope, it remains fixed, preventing it from being pulled backward. After locking via the positioning mechanism, the end of the drive cylinder 1 connected to the main beam 12 is moved, causing the drive cylinder 1 to retract. Then, the drive cylinder 1 is fixed to the main beam 12. After unlocking the positioning mechanism, the drive cylinder 1 is extended to push the piling platform further, thus achieving step-by-step movement of the piling platform. When the drive cylinder 1 applies a jacking force to the piling platform, the positioning mechanism can be unlocked, allowing relative movement between the piling platform and the main beam 12. This allows the piling platform to move to a designated position on the main beam 12 via rollers under jacking force. The positioning mechanism can switch between locked and unlocked states to achieve both fixing and movement of the piling platform, thereby overcoming the pull of the winch assembly wire rope.

[0033] In this embodiment, the other end of the drive cylinder 1 is connected to the main beam 12 via a locking mechanism 2. The locking mechanism 2 includes a locking cylinder 21 and a connecting frame 22. The locking cylinder 21 is installed inside the connecting frame 22. Here, the other end of the drive cylinder 1 is one end of the cylinder sleeve of the drive cylinder 1 shown in the figure, and the cylinder sleeve of the drive cylinder 1 is connected to the connecting frame 22. A slot 23 is formed at the lower part of the connecting frame 22, and the top plate of the main beam 12 can be engaged in the slot 23 to prevent the connecting frame 22 from detaching from the main beam 12 vertically. The locking cylinder 21 is vertically installed inside the connecting frame 22, locking... The cylinder liner of the locking cylinder 21 is fixedly connected to the connecting bracket 22. The piston of the locking cylinder 21 can extend downwards out of the cylinder liner so that its lower end abuts against the top of the main beam 12, thereby locking the locking mechanism 2 and keeping one end of the cylinder liner of the drive cylinder 1 relatively fixed to the main beam 12, preventing one end of the cylinder liner of the drive cylinder 1 from moving on the main beam 12. Similarly, the piston of the locking cylinder 21 can retract upwards into the cylinder liner so that the lower end of the piston leaves the upper surface of the main beam 12, thereby unlocking the locking mechanism 2, which allows one end of the cylinder liner of the drive cylinder 1 to move on the main beam 12.

[0034] Both ends of the drive cylinder 1 can be connected to the longitudinal platform 11 and the locking mechanism 2 by means of hinge. Specifically, both ends of the drive cylinder 1, namely the ends of the piston and the cylinder liner, can be provided with connecting seats. Corresponding connecting seats can also be provided at the corresponding positions of the longitudinal platform 11 and the locking mechanism 2. By opening pin holes on the connecting seats and driving pins into the pin holes, the drive cylinder 1, the longitudinal platform 11 and the locking mechanism 2 can be hinged.

[0035] Optionally, such as Figures 1 to 3 The first structure shown includes a positioning mechanism comprising multiple lifting cylinders 3 disposed at the bottom of the piling platform; for example... Figure 1 The bottom of the longitudinal moving platform 11 shown is provided with two lifting cylinders 3. The two lifting cylinders 3 are respectively installed on the front and rear sides of the longitudinal moving platform 11 along its moving direction. The cylinder sleeve of the lifting cylinder 3 is embedded in the bottom of the longitudinal moving platform 11 and is fixedly connected to the longitudinal moving platform 11. The piston of the lifting cylinder 3 can extend downward from the cylinder sleeve and abut against the top of the main beam 12.

[0036] Specifically, when the longitudinal platform 11 needs to move forward (i.e., Figure 1 When the longitudinal platform 11 moves to the left, the locking mechanism 2 needs to be locked first, that is, the piston of the locking cylinder 21 extends downward and abuts against the main beam 12, and the positioning mechanism is unlocked, that is, the piston of the lifting cylinder 3 retracts upward into the cylinder sleeve of the lifting cylinder 3. At this time, the longitudinal platform 11 can move downward a certain distance, so that the main wheel 8 at the bottom of the longitudinal platform 11 sits on the main beam 12. At the same time, the piston of the lifting cylinder 3 leaves the upper surface of the main beam 12. At this time, the drive cylinder 1 can be controlled to extend, that is, to extend the piston of the drive cylinder 1 from the cylinder sleeve, so that a pushing force is applied to the longitudinal platform 11, pushing the longitudinal platform 11 forward (that is, to the left in the figure) on the main beam 12 through the rollers. When the piston of the drive cylinder 1 extends to the maximum stroke and the longitudinal platform 11 has not yet moved into place, the positioning mechanism needs to be locked. The piston of the lifting cylinder 3 extends downward and presses against the main beam 12, pushing the longitudinal platform 11 upward and causing the main wheel 8 to leave the upper surface of the main beam 12. At the same time, the locking mechanism 2 is unlocked, that is, the piston of the locking cylinder 21 retracts upward into the cylinder sleeve of the locking cylinder 21 and leaves the upper surface of the main beam 12. Then, the drive cylinder 1 is controlled to retract, so that the piston of the drive cylinder 1 retracts into the cylinder sleeve of the drive cylinder 1, which can drive the cylinder sleeve of the drive cylinder 1 and the locking mechanism 2 to move. After the piston of the drive cylinder 1 is completely retracted into the cylinder sleeve of the drive cylinder 1, the above steps are repeated, that is, first the positioning mechanism is unlocked and the locking mechanism 2 is locked, then the drive cylinder 1 is extended to push the longitudinal platform 11 to move until the longitudinal platform 11 is moved to the designated position. Finally, the positioning mechanism is locked to fix the longitudinal platform 11 to the main beam 12.

[0037] Similarly, if it is necessary to make the longitudinal platform 11 face backward (i.e. Figure 1When the right side of the longitudinal moving platform 11 moves, if the initial state of the drive cylinder 1 is the extended state, as described above, the locking mechanism 2 needs to be locked first, and the positioning mechanism needs to be unlocked at the same time. Then, the drive cylinder 1 is controlled to retract, which can pull the longitudinal moving platform 11 to move to the right. If the longitudinal moving platform 11 still does not move to the position after the drive cylinder 1 is fully retracted, the positioning mechanism needs to be locked and the locking mechanism 2 needs to be unlocked. Then, the drive cylinder 1 is controlled to extend, which can push the locking mechanism 2 to move to the right. After the drive cylinder 1 extends to its maximum stroke, the above steps are repeated, that is, locking the locking mechanism 2, unlocking the positioning mechanism, and then retracting the drive cylinder 1 to pull the longitudinal moving platform 11 to continue to move to the right until the longitudinal moving platform 11 is moved to the designated position. Finally, the positioning mechanism is locked to fix the longitudinal moving platform 11 to the main beam 12.

[0038] Optionally, such as Figures 4 to 5 The second structure shown includes a positioning mechanism comprising a lead screw 4 mounted on one side of the main beam 12 and an ear plate 5 mounted on the bottom of the piling platform. The ear plate 5 is fitted onto the lead screw 4, and positioning nuts 6 are fitted onto both sides of the ear plate 5 on the lead screw 4. Here, the structure in which the lead screw 4, ear plate 5, and positioning nuts 6 are connected can serve as an alternative to the aforementioned lifting cylinder 3. That is, when the positioning mechanism includes the lead screw 4, ear plate 5, and positioning nuts 6, the lifting cylinder 3 need not be installed at the bottom of the longitudinal moving platform 11. Similarly, when the lifting cylinder 3 is installed at the bottom of the longitudinal moving platform 11, the lead screw 4 and ear plate 5 need not be installed in the device. Plate 5 and positioning nuts 6; specifically, when the positioning mechanism is locked, the positioning nuts 6 on both sides of the ear plate 5 need to be tightened onto the ear plate 5, that is, the positioning nuts 6 on both sides of the ear plate 5 are turned so that the positioning nuts 6 are pressed against both sides of the ear plate 5, so that the longitudinal moving platform 11 is fixed on the main beam 12; when the positioning mechanism is unlocked, the positioning nuts 6 on both sides of the ear plate 5 need to be loosened, and for the positioning nut 6 facing the moving direction of the longitudinal moving platform 11, it needs to be turned away from the ear plate 5, and the distance between the positioning nut 6 and the ear plate 5 should not be less than the single moving distance of the longitudinal moving platform 11. When using the lead screw 4, ear plate 5 and positioning nuts 6 as the positioning mechanism, the moving method of the longitudinal moving platform 11 can refer to the moving process of using the lifting cylinder 3 as the positioning mechanism described above. The switching of the locking and unlocking states of the positioning mechanism and the locking mechanism 2 is the same as the above process, and will not be described in detail here.

[0039] In this embodiment, the two ends of the lead screw 4 are fixedly connected to the main beam 12 via connecting rods 7. Here, the lead screw 4 is installed along the length of the main beam 12 on one side of the main beam 12 and is parallel to the main beam 12. The lead screw 4 needs to be spaced a distance from the main beam 12 to ensure that the ear plate 5 and the positioning nut 6 can be fitted onto the lead screw 4. Therefore, the lead screw 4 can be connected to the main beam 12 by setting connecting rods 7 at both ends of the lead screw 4, while maintaining a distance between the lead screw 4 and the main beam 12. The connecting rods 7 can be perpendicular to the side of the main beam 12. The connecting rods 7 can be fixedly connected to the main beam 12 and the lead screw 4 by welding or other means.

[0040] In this embodiment, the rollers include a main wheel 8 located at the top of the main beam 12 and side wheels 9 located on both sides of the main beam 12. The main wheel 8 is installed at the bottom of the longitudinal moving platform 11 and can contact the upper surface of the main beam 12. When the lifting cylinder 3 retracts, the main wheel 8 can bear the weight of the longitudinal moving platform 11 and roll on the main beam 12 as the longitudinal moving platform 11 moves. The side wheels 9 are installed on the wheel frame at the bottom of the longitudinal moving platform 11 and can contact the side of the main beam 12. Two side wheels 9 can be provided on each of the two sides of the main beam 12. That is, the two side wheels 9 on both sides of the main beam 12 can clamp the main beam 12 in the middle. The side wheels 9 can laterally limit the longitudinal moving platform 11 and prevent the movement trajectory of the main wheel 8 from deviating from the main beam 12, causing the longitudinal moving platform 11 to fall off the main beam 12.

[0041] Example 2 This embodiment provides a piling platform.

[0042] The piling platform of this embodiment includes a transverse platform 10, a longitudinal platform 11, and a fixed-distance moving device as in embodiment 1; the transverse platform 10 is disposed above the longitudinal platform 11, and the fixed-distance moving device is disposed on the longitudinal platform 11.

[0043] In this embodiment, a transverse slide rail 13 is provided between the transverse platform 10 and the longitudinal platform 11; the transverse slide rail 13 and the longitudinal platform 11 are perpendicular to each other in their movement direction, and the transverse platform 10 can slide laterally on the longitudinal platform 11 along the transverse slide rail 13.

[0044] Example 3 This embodiment provides a piling system.

[0045] The piling system of this embodiment includes a pile frame, a pile hammer (not shown in the figure), and a piling platform as in Embodiment 2. The pile frame is vertically set on the piling platform, and the pile hammer is installed on the pile frame. The pile hammer is used to hammer the top of the pipe pile to carry out the piling operation.

[0046] Example 4 This embodiment provides a pile-beam integrated machine.

[0047] The integrated pile-beam machine of this embodiment includes a main beam 12 and a pile driving system as shown in Embodiment 3, wherein the pile driving system is installed on the main beam 12. Specifically, the pile driving system is installed on the main beam 12 near the end of the main beam 12 facing the direction of advancement of the integrated pile-beam machine through the bridge span.

[0048] In summary, this utility model provides a fixed-distance moving device for a piling platform, a piling platform, a system, and an integrated pile-beam machine. By employing a step-type fixed-distance moving device, a drive cylinder is installed on one side of the piling platform. The drive cylinder pushes the piling platform to move. Simultaneously, a positioning mechanism and rollers are installed between the piling platform and the main beam. The positioning mechanism can lock the piling platform onto the main beam after the drive cylinder extends to its maximum stroke, thus fixing the piling platform relative to the main beam. This ensures that even when the pushing force of the drive cylinder is released and the system is subjected to the tension of the winch assembly's wire rope, the piling platform remains stationary. To prevent the piling platform from being pulled backward, the positioning mechanism locks the piling platform in place. Then, the end of the drive cylinder connected to the main beam is moved, causing the drive cylinder to retract. Afterward, the drive cylinder is fixed to the main beam, and the positioning mechanism is unlocked. The drive cylinder then extends to push the piling platform further, achieving step-by-step movement. When the drive cylinder applies a jacking force to the piling platform, the positioning mechanism can be unlocked, allowing relative movement between the piling platform and the main beam. This allows the piling platform to move to the designated position on the main beam via rollers under jacking force. The positioning mechanism can switch between locked and unlocked states to achieve both fixing and movement of the piling platform, thus overcoming the backward pull of the winch assembly's wire rope.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
