DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. If not specifically indicated, the technical means used in the embodiments are conventional means familiar to those skilled in the art.
[0029] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
[0030] The embodiment of the present application provides a sliding mode hydraulic lifting device, which comprises a support rod 2 and a lifting assembly 3. The support rod 2 is used for being inserted between the forms of a lifting frame 1, the support rod 2 comprises an inner rod 14 and an outer rod 13 sleeved on the inner rod 14, and a plurality of positioning holes 4 are arranged at intervals in the circumferential wall of the outer rod 13 in the axial direction of the outer rod 13.
[0031] The lifting assembly 3 comprises a first ring body 5, a second ring body 6 and a hydraulic component 9, the first ring body 5 and the second ring body 6 are sleeved on the support rod 2, the first ring body 5 is arranged above the second ring body 6 when the support rod 2 extends vertically in the axial direction, the first ring body 5 is provided with a first inserting part 7, the second ring body 6 is provided with a second inserting part 8, the first inserting part 7 and the second inserting part 8 are selectively inserted into the positioning holes 4 respectively, the first inserting part 7 is configured to be inserted into the corresponding positioning hole 4 when the first ring body 5 moves from top to bottom, and the hydraulic component 9 is arranged on the second ring body 6, the hydraulic component 9 comprises a movable end 12, and the movable end 12 is connected to the first ring body 5.
[0032] The support rod 2 is used for supporting the whole sliding formwork system, and when the construction is carried out, the support rod 2 is inserted into the concrete structure.
[0033] The support rod 2 comprises the inner rod 14 and the outer rod 13, on the one hand, the risk that the structural strength of the support rod 2 is reduced due to the fact that the positioning holes 4 are arranged on the outer rod 13 is reduced, and on the other hand, the inner and outer sleeving structure makes the inner rod 14 easy to be disassembled after the construction is completed.
[0034] Since the support rod 2 is provided with two rods in an inner and outer sleeving mode, the overall structural strength of the support rod 2 is increased, so in the embodiment of the present application, a plurality of lifting frames 1 can be supported by one support rod 2, so that the cost does not increase due to the increase in the number of constituent rods of the support rod 2, but the construction cost can be reduced. For example, two lifting frames 1 can be supported by one support rod 2.
[0035] In the embodiment of the present application, the lifting frame 1 can be connected to the second ring body 6.
[0036] The hydraulic component 9 can be a hydraulic cylinder, and the movable end 12, i.e., the telescopic end of the hydraulic cylinder, is a mature prior art, and those skilled in the art can select a suitable type according to needs when implementing the present solution.
[0037] The first inserting part 7 and the second inserting part 8 are respectively used for axially limiting the first ring body 5 and the second ring body 6, so that the first ring body 5 and the second ring body 6 can be fixed in the axial position of the support rod 2. The first ring body 5 and the second ring body 6 form an integral whole under the connection of the hydraulic component 9, thereby increasing the fixing reliability of the lifting assembly 3 to the lifting frame 1.
[0038] When the first inserting part 7 is withdrawn from the corresponding positioning hole 4, the first ring body 5 can move along the support rod 2. When the second inserting part 8 is withdrawn from the corresponding positioning hole 4, the second ring body 6 can move along the support rod 2.
[0039] When the lifting assembly 3 climbs along the support rod 2, the first inserting part 7 is first withdrawn from the positioning hole 4, then the first ring body 5 is jacked up by the hydraulic component 9, after the first ring body 5 is moved into position, the first inserting part 7 is reinserted into the positioning hole 4, then the second inserting part 8 is withdrawn from the positioning hole 4, and then the second ring body 6 is jacked up by the hydraulic component 9, so that the lifting assembly 3 can carry the lifting frame 1 to move along the support rod 2.
[0040] The first inserting part 7 is configured to be inserted into the corresponding positioning hole 4 when the first ring body 5 moves from top to bottom, which means that when the first ring body 5 is jacked up by the hydraulic component 9, the first inserting part 7 will not be inserted into the positioning hole 4 during the rising process of the first ring body 5, when the hydraulic component 9 returns oil and the movable end 12 moves into the cylinder body of the hydraulic cylinder, the movable end 12 drives the first ring body 5 to move downward, when the first ring body 5 moves to the position of the nearest positioning hole 4, the first inserting part 7 is inserted into the positioning hole 4. The advantages of this arrangement are as follows. On the one hand, the control accuracy requirement of the hydraulic component 9 is reduced, for example, the distance between the positioning holes 4 is 10 cm, and the lifting is required to be 20 cm, then the first ring body 5 can be controlled to rise to an arbitrary position between 20 cm and 30 cm, and then the first ring body 5 is lowered and the first inserting part 7 is inserted into the positioning hole 4. On the other hand, the lifting accuracy is ensured, i.e., through the cooperation of the first inserting part 7, the second inserting part 8, and the positioning hole 4, the lifting assembly 3 can carry the lifting frame 1 to climb a set distance. On the other hand, the lifting frame 1 is connected to the second ring body 6, and when the position of the first ring body 5 is adjusted to ensure the positioning accuracy, the movement of the first ring body 5 will not drive the lifting frame 1 to move, thereby reducing the burden of the hydraulic component 9, and reducing the number of times the lifting frame 1 needs to move during adjustment, and improving the construction safety.
[0041] In some embodiments, the first ring body 5 is provided with a first sliding hole 16, the first sliding hole 16 extends radially along the first ring body 5, the first insertion part 7 is inserted into the first sliding hole 16, and a first elastic member 15 is provided between the first insertion part 7 and the first sliding hole 16. The first elastic member 15 is used to provide an elastic force for inserting the first insertion part 7 into the corresponding positioning hole 4.
[0042] Under the action of the first sliding hole 16, the first insertion part 7 can move relative to the first ring body 5.
[0043] The first elastic element 15 can be a spring.
[0044] In some embodiments, the first ring body 5 is provided with a second sliding hole 17, the second sliding hole 17 communicates with the peripheral wall of the first sliding hole 16, the second sliding hole 17 extends along the axial direction of the first ring body 5, the second sliding hole 17 is provided on the side of the first ring body 5 near the second ring body 6, the movable end 12 abuts against the first insertion part 7 via the second sliding hole 17, the contact surface between the movable end 12 and the first insertion part 7 is an inclined surface, the peripheral wall of the movable end 12 is provided with a limiting ring 18, the inner wall of the second sliding hole 17 is provided with a protruding ring 19, and the limiting ring 18 is provided on the side of the protruding ring 19 away from the second ring body 6.
[0045] Under the action of the second sliding hole 17, the movable end 12 can be inserted into the first sliding hole 16 and contact the first insertion part 7.
[0046] The contact surface between the first insertion part 7 and the movable end 12 is an inclined surface, so that when the movable end 12 lifts the first ring body 5, the movable end 12 can push the first insertion part 7 to move away from the axis of the first ring body 5.
[0047] Furthermore, the second sliding hole 17 can limit the movement of the movable end 12, thereby improving the structural strength of the hydraulic component 9.
[0048] The limiting ring 18 and the protruding ring 19 cooperate to limit the movable end 12, preventing it from detaching from the first ring body 5. When the movable end 12 moves downward, it no longer contacts the first insertion part 7. At this time, under the action of the first elastic member 15, the first insertion part 7 abuts against the outer wall of the support rod 2. Under the action of friction, the first ring body 5 can remain stationary. As the movable end 12 continues to move downward, when the first insertion part 7 aligns with the positioning hole 4, it inserts into the positioning hole 4, and the position of the first ring body 5 is fixed. When the first ring body 5 remains stationary, it is convenient to measure its position. For example, the second ring body 6 can be equipped with a measuring component to measure the distance between the first ring body 5 and the second ring body 6. The first ring body 5 remains stationary before the limiting ring 18 and the protruding ring 19 contact. At this time, the measuring component can accurately measure the distance between the first ring body 5 and the second ring body 6. If the first ring body 5 has not moved into place, it can be adjusted in time.
[0049] Furthermore, if the movable end 12 is rigidly connected directly to the first ring body 5, the movement of the movable end 12 will be fed back to the first ring body 5 in real time, causing the first ring body 5 to move frequently and increasing the wear of the first ring body 5. Under the action of the limiting ring 18 and the protruding ring 19, the frequency of movement of the first ring body 5 is reduced, thereby reducing the wear of the first ring body 5.
[0050] In some embodiments, the second ring body 6 is provided with a third sliding hole, the third sliding hole extends radially along the second ring body 6, the second insertion part 8 is inserted into the third sliding hole, and a second elastic member is provided between the second insertion part 8 and the third sliding hole. The second elastic member is used to provide an elastic force to make the second insertion part 8 exit the corresponding positioning hole 4.
[0051] Under the action of the third sliding hole, the second insertion part 8 can move relative to the second ring body 6.
[0052] The second elastic element can be a spring. The second elastic element is used to provide an elastic force to disengage the second insertion part 8 from the corresponding positioning hole 4, so that when the hydraulic component 9 lifts the second ring body 6, the friction between the second insertion part 8 and the positioning hole 4 is reduced, allowing the second insertion part 8 to disengage from the positioning hole 4 under the action of the second elastic element.
[0053] In some embodiments, the third sliding hole penetrates the second ring body 6 radially. The lifting assembly 3 further includes a striking component 10, which includes a striking wheel 23, a positioning part 22, and a firing unit. The striking wheel 23 is rotatably connected to the second ring body 6, and the rotation axis of the striking wheel 23 is perpendicular to the axial direction of the second ring body 6. The striking wheel 23 is used to strike the side of the second insertion part 8 away from the axis of the second ring body 6. A locking groove 25 is provided on the peripheral wall of the striking wheel 23. A third elastic element is provided between the striking wheel 23 and the second ring body 6. The positioning part 22 is rotatably connected to the second ring body 6, and the rotation axis of the positioning part 22 is parallel to that of the striking wheel 23. A fourth elastic element is provided between the positioning part 22 and the second ring body 6. The positioning part 22 is configured to insert into the locking groove 25 when the striking wheel 23 rotates clockwise to a set position, so as to prevent the striking wheel 23 from rotating counterclockwise. The firing unit is movably connected to the second ring body 6 along the axial direction of the second ring body 6. The firing unit is configured such that when the second ring body 6 moves toward the first ring body 5, the firing unit pushes the positioning part 22 to rotate, so that the positioning part 22 rotates out of the locking groove 25.
[0054] The striking wheel 23 may be provided with a striking block. When the striking wheel 23 rotates, the striking block strikes the second insertion part 8, so that the striking wheel 23 can push the second insertion part 8 to move toward the axis of the second ring body 6.
[0055] The third and fourth elastic elements can be springs or torsion springs.
[0056] The third elastic element allows the striking wheel 23 to rotate and strike the second insertion part 8 when it is released.
[0057] The clockwise rotation of the striking wheel 23 means, according to Figure 5 and Figure 7 As shown, the striking wheel 23 rotates clockwise, and similarly, the positioning part 22 also rotates clockwise. Figure 5 and Figure 7 The state shown can be rotated clockwise or counterclockwise.
[0058] The position of the positioning part 22 relative to the striking wheel 23, and the position of the locking groove 25 of the striking wheel 23, can be set as needed during specific implementation, as long as it ensures that when the striking wheel 23 rotates clockwise to a certain position, the positioning part 22 abuts against the outer peripheral wall of the striking wheel 23. The fourth elastic member provides the elastic force that makes the positioning part 22 abut against the outer peripheral wall of the striking wheel 23. Afterwards, the striking wheel 23 rotates counterclockwise, and the positioning part 22 engages with the locking groove 25, so that the positioning part 22 can limit the striking wheel 23.
[0059] When the second ring 6 moves toward the first ring 5, the firing unit pushes the positioning part 22 to rotate, causing the positioning part 22 to rotate out of the locking groove 25. At this time, the striking wheel 23 strikes the second insertion part 8 under the third elastic member. The reaction force provided by the second elastic member can buffer the second insertion part 8, reducing the risk of the second insertion part 8 rebounding after hitting the inner rod 14 after being inserted into the positioning hole 4. Finally, under the action of the striking wheel 23, the second insertion part 8 remains inserted in the positioning hole 4.
[0060] The advantage of using the striking wheel 23 to move the second insertion part 8 is that when the second ring 6 moves towards the first ring 5 to the set position, the striking wheel 23 can promptly push the second insertion part 8 into the positioning hole 4, improving construction safety. On the other hand, this increases the length of the second insertion part 8 inserted into the positioning hole 4, thereby improving the reliability of the second ring 6's support for the lifting frame 1. Specifically, if the second insertion part 8 gradually moves towards the axis of the second ring 6 as it moves towards the first ring 5, then when the second ring 6 is in place, the length of the second insertion part 8 inserted into the positioning hole 4 is relatively small. However, the striking wheel 23 can quickly push the second insertion part 8 into the positioning hole 4, increasing the length of the second insertion part 8 that can be inserted into the positioning hole 4.
[0061] In some embodiments, the firing unit includes a moving part 21, a pushing part 20, a first actuating part 27, a limiting part 28, and a second actuating part 26. The moving part 21 is movably connected to the second ring body 6 along the axial direction of the second ring body 6. The pushing part 20 is connected to the first ring body 5 and is used to push the moving part 21 to move. The first actuating part 27 is rotatably disposed on the moving part 21 and is used to actuate the striking wheel 23 clockwise. The limiting part 28 is disposed on the moving part 21 and is used to limit the clockwise rotation of the first actuating part 27. The second actuating part 26 is disposed on the moving part 21 and is used to actuate the positioning part 22.
[0062] When the first ring 5 moves away from the second ring 6, the second actuating part 26 first flips over the positioning part 22. A clearance part can be provided on the outer peripheral wall of the striking wheel 23, allowing the second actuating part 26 to rotate the positioning part 22 clockwise. (Ref) Figure 5 and Figure 7 )
[0063] The rotation direction of the first actuating part 27 can be perpendicular to the axial direction of the second ring body 6.
[0064] Subsequently, the first actuating part 27 actuates the striking wheel 23 to rotate clockwise, so that the positioning part 22 can be engaged into the locking groove 25.
[0065] When the second ring 6 moves toward the first ring 5, the pushing part 20 pushes the moving part 21 to move toward the second ring 6, and then the second actuating part 26 pushes the positioning part 22 to rotate, so that the positioning part 22 exits from the locking slot 25, the striking wheel 23 is released, and the second insertion part 8 is pushed to move.
[0066] The limiting part 28 is disposed on the side of the first actuating part 27 away from the first ring body 5. This arrangement allows the first actuating part 27 to rotate counterclockwise when it contacts the striking wheel 23, without causing the striking wheel 23 to rotate, while the first actuating part 27 can rotate counterclockwise when it moves away from the first ring body 5 due to the limiting effect of the limiting part 28. This allows the first actuating part 27 to cause the striking wheel 23 to rotate.
[0067] In some embodiments, the movable part 21 is provided with an elastic notch 24 at one end near the first ring body 5, the opening of the elastic notch 24 faces the first ring body 5, and the pushing part 20 is engaged in the elastic notch 24.
[0068] The moving part 21 is located near the end of the first ring body 5, or the moving part 21 as a whole can be made of a material that can produce elastic deformation, such as spring steel.
[0069] Under the action of elastic deformation, the two side arms of the elastic notch 24 can separate a distance and then return to their original position.
[0070] When the first ring 5 moves away from the second ring 6, the pushing part 20 first drives the moving part 21 to move, so that the second actuating part 26 is positioned on the side of the positioning part 22 closer to the first ring 5. The positioning part 22 is engaged in the engaging groove 25. As the first ring 5 moves further, the pushing part can disengage from the elastic notch 24, at which point the pushing part 20 and the moving part 21 are disconnected. When the second ring 6 moves towards the first ring 5, the pushing part 20 can engage in the elastic notch 24 again, pushing the moving part 21 towards the second ring 6.
[0071] The advantages of this design are twofold: firstly, it ensures that the stroke of the moving part 21 does not restrict the stroke of the first ring body 5; secondly, during the movement of the first ring body 5, the pushing part 20 and the moving part 21 are disconnected, reducing the risk of accidental contact; and thirdly, it reduces the resistance to the movement of the first ring body 5. Furthermore, when the second ring body 6 moves towards the first ring body 5 and the pushing part 20 contacts the moving part 21, the two side arms of the elastic notch 24 can absorb the impact load. Moreover, before the pushing part 20 is fully engaged in the elastic notch 24, a certain positional deviation between the pushing part 20 and the moving part 21 is permissible; after the pushing part 20 is fully engaged in the elastic notch 24, the pushing part 20 and the moving part 21 can form a rigid connection, ensuring the precise control accuracy of the pushing part 20 over the moving part 21.
[0072] In this embodiment, the interior of the elastic notch 24 can be circular, the opening size of the elastic notch 24 is smaller than the diameter of the interior of the elastic notch 24, and the cross-section of the pushing part 20 is circular. When the pushing part 20 is fully inserted into the elastic notch 24, the pushing part 20 enters the circular inner wall area of the elastic notch 24.
[0073] In some embodiments, a limiting component 11 is further included, the limiting component 11 comprising a first rod 29, a second rod 30, and a plurality of spiral cables 31. The first rod 29 is connected to the first ring 5, and the second rod 30 is connected to the second ring 6, the first rod 29 and the second rod 30 being movably connected. The two ends of the plurality of spiral cables 31 are respectively connected to the first ring 5 and the second ring 6, and the spiral cables 31 are spiral in shape.
[0074] A limiting structure can be provided between the first rod 29 and the second rod 30 to prevent the first rod 29 from detaching from the second rod 30. The limiting structure can be selected from existing technologies and will not be described in detail here. This arrangement allows the first rod 29 and the second rod 30 to cooperate, which can improve the positional accuracy of the relative movement of the first ring 5 and the second ring 6, and reduce the risk of the first ring 5 and the second ring 6 breaking apart.
[0075] As the overall structure formed by the first rod 29 and the second rod 30 increases, the spiral cable 31 is taut, and the bolt cable can be tightly wrapped around the outer peripheral walls of the first rod 29 and the second rod 30. At this time, the resistance to the relative movement of the first rod 29 and the second rod 30 increases.
[0076] The maximum length of the overall structure formed by the first rod 29 and the second rod 30 can be greater than the maximum stroke of the hydraulic component 9 driving the first ring 5 to move.
[0077] The spiral cable 31 improves the overall safety of the device. Even in extreme cases where the hydraulic component 9 cannot connect the first ring 5 and the second ring 6, and the first rod 29 and the second rod 30 are disconnected, the spiral groove can still connect the first ring 5 and the second ring 6. On the other hand, the spiral cable 31 can adjust the friction between the first rod 29 and the second rod 30, acting as a buffer. Specifically, during the climbing process, there is a moment when the second insertion part 8 of the second ring 6 exits the positioning hole 4, and the lifting frame 1 is fixed to the support rod 2 via the first ring 5. If the hydraulic component 9 malfunctions at this time, since the lifting frame 1 is connected to the second ring 6, the second ring 6 will fall rapidly. When it reaches the maximum length of the overall structure formed by the first rod 29 and the second rod 30, the first rod 29 and the second rod 30 may disconnect under the impact force. At the same time, the first ring 5 will be subjected to the impact force, which may damage the first insertion part 7. Under the action of the spiral cable 31, when the second ring 6 falls rapidly, the spiral cable 31 can increase the connection strength between the first rod 29 and the second rod 30 to prevent them from breaking. On the other hand, the spiral cable 31 tightens the first rod 29 and the second rod 30, which increases the friction between the first rod 29 and the second rod 30, buffering the impact force generated by the rapid descent of the second ring 6. This reduces the risk of damage to the first insertion part 7 and breakage of the first rod 29 and the second rod 30, and improves construction safety.
[0078] Furthermore, under normal operating conditions, since the spiral cable 31 is not taut, it will not increase the friction between the first rod 29 and the second rod 30, and thus will not create resistance to the movement of the first ring 5.
[0079] Another advantage of using the spiral cable 31 is that it makes the overall structure of the limiting component 11 very small, making it suitable for use in slipform construction in confined spaces.
[0080] In some embodiments, the limiting component 11 further includes a rotating disk 32, which is rotatably connected to the second ring body 6, and the spiral cable 31 is connected to the second ring body 6.
[0081] The second ring 6 can be equipped with a locking structure to unlock or lock the rotating disk 32. When unlocked, the rotating disk 32 can be selected; conversely, when locked, the rotating disk 32 is fixed. Many mature locking structures exist in the prior art; simply choose an appropriate type.
[0082] By rotating the rotary disk 32, the number of spiral turns of the spiral cable 31 can be adjusted. After the adjustment is completed, the rotary disk 32 is locked. At this time, the resistance formed by the spiral cable 31 on the first rod 29 and the second rod 30 can be adjusted. Furthermore, when the first rod 29 and the second rod 30 are separated, the length of the overall structure formed by the first rod 29 and the second rod 30 can also be adjusted.
[0083] In some embodiments, multiple limiting components 11 are provided around the circumference of the support rod 2.
[0084] By setting multiple limit components 11, the safety protection effect of the limit components 11 on the enhanced component 3 is increased.
[0085] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
