Description

Technical Field

[0001] This utility model relates to the field of bridge engineering, and in particular to a formwork lifting tool. Background Technology

[0002] Portal piers are rigidly connected by double columns and a top beam, forming a portal frame structure with a large span between columns. They are often used in situations where it is impossible to install intermediate piers, commonly seen in new lines crossing existing railways or highways, and also suitable for areas with heavy traffic and dense pipelines underneath. This structure allows for a pier-free, open space underneath, minimizing traffic interference, and features strong spanning capacity, high overall rigidity, and minimal land occupation.

[0003] The construction of portal piers spanning existing railway lines involves building portal frame piers above normally operating railway or highway lines, typically using a cast-in-place scaffolding method. However, due to the presence of existing railway lines below, there are limitations in working space and the inability to erect full-span scaffolding for formwork assembly. In particular, the bottom formwork presents challenges in terms of lifting stability and ease of installation. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem of the difficulty in installing cast-in-place formwork for portal piers in the existing technology, and to provide a formwork lifting tool.

[0005] In a first aspect, this utility model provides a formwork lifting device, comprising: a lifting beam, a connecting vertical beam, a load-bearing beam, a snap-fit ​​structure, and a stopper, wherein:

[0006] The upper end of the connecting vertical beam is connected to the hoisting beam, and the lower end of the connecting vertical beam is connected to the load-bearing beam to form a C-shaped structure; The snap-fit ​​structure is slidably mounted on the bearing beam, and the snap-fit ​​structure has a snap-fit ​​part for passing through the snap-fit ​​hole of the template; The stop and the snap-fit ​​structure are spaced apart along the length of the load-bearing beam. The stop has a through hole, which corresponds to the snap-fit ​​hole. The snap-fit ​​part is detachably inserted through the through hole, and the stop is located on the side of the snap-fit ​​hole facing away from the snap-fit ​​part.

[0007] Optionally, the snap-fit ​​structure further includes a slide rod, which is movably inserted through the stop member, and the snap-fit ​​part is fixedly connected to the slide rod to drive the snap-fit ​​part to insert into or disengage from the through hole.

[0008] Optionally, the load-bearing beam includes a first load-bearing beam and a second load-bearing beam, the first load-bearing beam and the second load-bearing beam are spaced apart along the width direction of the load-bearing beam, and the slide bar is disposed between the first load-bearing beam and the second load-bearing beam; The snap-fit ​​structure also includes a limiting plate, which is connected to the slide rod. The two ends of the limiting plate are slidably connected to the sides of the first bearing beam and the second bearing beam near the slide rod, respectively.

[0009] Optionally, there are two slide rods, which are spaced apart along the width direction of the bearing beam. The snap-fit ​​part is disposed between the two slide rods and connected to each of the two slide rods respectively. The limiting plate is fixedly connected to each of the two slide rods respectively.

[0010] Optionally, the connecting vertical beam includes a first connecting vertical beam and a second connecting vertical beam, and the formwork lifting device also includes a connecting seat. The first connecting vertical beam and the load-bearing beam are both connected to the connecting seat, and the two ends of the second connecting vertical beam are detachably connected to the first connecting vertical beam and the lifting beam, respectively.

[0011] Optionally, a plurality of first connecting holes are formed at one end of the second connecting beam near the first connecting beam, and the plurality of first connecting holes are spaced apart along the length direction of the second connecting beam. A second connecting hole corresponding to the first connecting hole is formed at one end of the first connecting beam near the second connecting beam. The connecting vertical beam also includes a connector, which passes through the first connecting hole and the second connecting hole in sequence to connect the first connecting vertical beam and the second connecting vertical beam.

[0012] Optionally, the connecting vertical beam further includes a third connecting vertical beam, with both ends of the second connecting vertical beam connected to the first connecting vertical beam and the third connecting vertical beam respectively, and the other end of the third connecting vertical beam connected to the hoisting beam; The second connecting vertical beam has a plurality of third connecting holes at one end near the third connecting vertical beam. The plurality of third connecting holes are spaced apart along the length of the second connecting vertical beam. The third connecting vertical beam has a fourth connecting hole at one end near the second connecting vertical beam, which is corresponding to the third connecting holes.

[0013] Optionally, the connecting vertical beam further includes a connecting cylinder, with one end of the first connecting vertical beam and the third connecting vertical beam respectively passing through both ends of the connecting cylinder.

[0015] Optionally, the template lifting device further includes a driving mechanism, which is connected to the snap-fit ​​structure to drive the snap-fit ​​part to insert into or disengage from the snap-fit ​​hole.

[0016] Since the bottom formwork is typically installed after the side formwork, the above technical solution uses a C-shaped structure formed by the hoisting beam, connecting vertical beam, and load-bearing beam. Placing the formwork on the load-bearing beam allows the bottom formwork to be hoisted below the side formwork while avoiding obstruction, thus completing the bottom formwork installation. Simultaneously, the snap-fit ​​structure secures the formwork to the load-bearing beam, preventing it from detaching during hoisting and protecting the overhead lines. Positioning the stop on the side of the snap-fit ​​hole facing away from the snap-fit ​​part allows for clamping from both sides, improving clamping stability. Furthermore, the snap-fit ​​structure is adjustable, allowing it to secure formwork of different sizes to the load-bearing beam. Attached Figure Description

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0022] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0024] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0025] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0026] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0027] Example 1 like Figures 1 to 4 As shown, a formwork lifting device 100 includes a lifting beam 1, a connecting vertical beam 2, and a supporting beam 3. Both ends of the connecting vertical beam 2 are connected to the lifting beam 1 and the supporting beam 3 respectively, forming a C-shaped structure. The formwork lifting device 100 also includes a snap-fit ​​structure 4, which is slidably mounted on the supporting beam 3. The snap-fit ​​structure 4 has a snap-fit ​​portion 41 for passing through snap-fit ​​holes in the formwork. The formwork lifting device 100 also includes a stop member 5, which is spaced apart from the snap-fit ​​structure 4 along the length of the supporting beam 3. The stop member 5 has a through hole 51, which corresponds to the snap-fit ​​hole. The snap-fit ​​portion 41 is detachably inserted through the through hole 51, and the stop member 5 is located on the side of the snap-fit ​​hole facing away from the snap-fit ​​portion 41.

[0028] When hoisting formwork using the aforementioned formwork lifting device 100, the formwork can first be placed on the supporting beam 3 of the formwork lifting device 100, and the formwork should be abutted against the stop member 5, so that the snap-fit ​​hole on the formwork aligns with the through hole 51 on the stop member 5. Then, the snap-fit ​​part 41 passes through both the through hole 51 and the snap-fit ​​hole simultaneously, thereby clamping the formwork on both sides. After the formwork is installed, the crane hook can be connected to the lifting beam 1 to lift the formwork.

[0029] Meanwhile, since the snap-fit ​​structure 4 is slidably set on the bearing beam 3, it can move along the length of the bearing beam 3. When fixing the template, the snap-fit ​​structure 4 can move toward the stop 5, so that the snap-fit ​​part 41 passes through the snap-fit ​​hole and the through hole 51. After the template is installed, the snap-fit ​​structure 4 can move in the opposite direction and exit the snap-fit ​​hole and the through hole 51.

[0030] Since the bottom formwork is usually installed after the side formwork, the above technical solution uses a C-shaped structure formed by the hoisting beam 1, connecting vertical beam 2, and bearing beam 3. The formwork is placed on the bearing beam 3, allowing the bottom formwork to be hoisted below the side formwork while avoiding obstruction, thus completing the bottom formwork installation. Simultaneously, the snap-fit ​​structure 4 secures the formwork to the bearing beam 3, ensuring it doesn't detach during hoisting and protecting the safety of the overhead lines. The stop 5 is positioned on the side of the snap-fit ​​hole facing away from the snap-fit ​​part 41, allowing the snap-fit ​​part 41 and the stop 5 to be clamped from both sides, improving clamping stability. Furthermore, since the position of the snap-fit ​​structure 4 is adjustable, it can fix formwork of different sizes to the bearing beam 3.

[0031] To facilitate the movement of the snap-fit ​​structure 4, optionally, such as Figure 4 As shown, the snap-fit ​​structure 4 also includes a slide rod 42, which is movably inserted through the stop member 5. The snap-fit ​​part 41 is fixedly connected to the slide rod 42 so as to drive the snap-fit ​​part 41 to insert into or disengage from the through hole 51. The stop member 5 may have a connecting through hole 51. One end of the slide rod 42 may be connected to the drive mechanism 7, and the other end of the slide rod 42 may be inserted through the connecting through hole 51.

[0032] Because the slide rod 42 can achieve long-stroke linear motion and has the characteristics of simple structure and convenient disassembly and maintenance, using the slide rod 42 to drive the locking part 41 to move can improve the operational stability of the locking structure 4. At the same time, because the slide rod 42 has low manufacturing cost, it can also reduce the cost of the formwork lifting device 100.

[0033] Optionally, the template lifting device 100 also includes a drive mechanism 7, which is connected to the snap-fit ​​structure 4 to drive the snap-fit ​​part 41 to insert or disengage from the snap-fit ​​hole.

[0034] This utility model does not limit the specific embodiments of the drive mechanism 7. In one possible implementation, the drive mechanism 7 can be a cylinder, with the cylinder body fixed on the supporting beam 3. One end of the piston cylinder passes through the cylinder body, and the other end is connected to the slide rod 42. In other embodiments, the drive mechanism 7 can also be a hydraulic cylinder, an electric push rod, a lead screw and nut pair, etc.

[0035] To further improve the stability of the sliding bar 42's movement, optionally, such as Figure 1 and Figure 2As shown, the supporting beam 3 includes a first supporting beam 31 and a second supporting beam 32, which are spaced apart along the width direction of the supporting beam 3. A sliding rod 42 is positioned between the first supporting beam 31 and the second supporting beam 32. The locking structure 4 also includes a limiting plate 43, which is connected to the sliding rod 42. Both ends of the limiting plate 43 are slidably connected to the sides of the first supporting beam 31 and the second supporting beam 32 near the sliding rod 42, respectively. When the sliding rod 42 moves between the first supporting beam 31 and the second supporting beam 32, it drives the limiting plate 43 to move synchronously. Since the limiting plate 43 is simultaneously slidably connected to the sides of the first supporting beam 31 and the second supporting beam 32, the first supporting beam 31 and the second supporting beam 32 can restrict the range of motion of the limiting plate 43 to between the two supporting beams 3, thereby further ensuring that the sliding rod 42 will not deviate during movement and further improving the stability of the locking structure 4.

[0036] At the same time, the structure of the two load-bearing beams 3 can also improve the rigidity and stability of the load-bearing structure of the formwork hoist 100, and further enhance the load-bearing capacity of the formwork hoist 100.

[0037] This utility model does not limit the specific type of the load-bearing beam 3, which can be an I-beam, an H-beam, or a box beam, etc. In this utility model, the load-bearing beam 3 can be an I-beam, and the two ends of the limiting plate 43 can be slidably connected to the grooves on both sides of the I-beam to further enhance the limiting effect of the limiting plate 43.

[0038] Optionally, such as Figure 4 As shown, there are two sliding rods 42, spaced apart along the width of the supporting beam 3. A locking part 41 is positioned between the two sliding rods 42 and connected to each of them. A limiting plate 43 is fixedly connected to each of the two sliding rods 42. The arrangement of two sliding rods 42 and their fixed connection to the limiting plate 43 improves the overall rigidity of the locking structure 4, reduces swaying during movement, and lowers the probability of deformation under stress. Simultaneously, both sliding rods 42 pass through the stop member 5, providing mutual restraint and further preventing deviation during sliding.

[0039] Meanwhile, the locking part 41 is located between the two slide rods 42. With the support of the two slide rods 42, the wobbling of the locking part 41 during movement can be reduced, which is conducive to the precise matching of the locking part 41 with the locking hole and the through hole 51.

[0040] To increase the versatility of the formwork lifting device 100, optionally, such as Figure 3As shown, the connecting vertical beam 2 includes a first connecting vertical beam 21 and a second connecting vertical beam 22. The formwork lifting device 100 also includes a connecting seat 6. Both the first connecting vertical beam 21 and the supporting beam 3 are connected to the connecting seat 6. The two ends of the second connecting vertical beam 22 are detachably connected to the first connecting vertical beam 21 and the lifting beam 1, respectively. In this utility model, the formwork lifting device 100 is installed by spanning across one side of the side formwork to lift the bottom formwork to the bottom of the side formwork. By setting the second connecting vertical beam 22 to be detachably connected to the first connecting vertical beam 21 and the lifting beam 1, the length of the second connecting vertical beam 22 can be changed or adjusted for side formwork of different heights, thereby allowing the formwork lifting device 100 to be spanning across different side formworks, increasing the versatility of the formwork lifting device 100.

[0041] Optionally, such as Figure 2 As shown, the connecting seat 6 may include a first connecting plate 61, a second connecting plate 62 and a plurality of reinforcing plates 63. The first connecting plate 61 and the second connecting plate 62 are spaced apart. One end of the first connecting vertical beam 21 is located between the first connecting plate 61 and the second connecting plate 62 and is connected to the first connecting plate 61 and the second connecting plate 62 respectively. One end of the bearing beam 3 passes through the first connecting plate 61 and the second connecting plate 62 respectively and is connected to the first connecting plate 61 and the second connecting plate 62.

[0042] Multiple reinforcing plates 63 are provided at the gap between the first connecting plate 61 and the second connecting plate 62, and both ends of the multiple reinforcing plates 63 are respectively connected to the first connecting plate 61 and the second connecting plate 62.

[0043] The connecting seat 6 is the connection point between the load-bearing beam 3 and the connecting vertical beam 2, and it is also the stress point when the formwork hoisting tool 100 hoists the formwork. The first connecting plate 61, the second connecting plate 62, and multiple reinforcing plates 63 are set here to strengthen the structural strength of the connection and ensure safety during construction operations.

[0044] This utility model does not limit the specific structure of the second connecting vertical beam 22. In one possible implementation, such as Figure 3 As shown, the second connecting vertical beam 22 has a plurality of first connecting holes 221 formed at one end near the first connecting vertical beam 21. The plurality of first connecting holes 221 are spaced apart along the length direction of the second connecting vertical beam 22. The first connecting vertical beam 21 has a second connecting hole 211 formed at one end near the second connecting vertical beam 22, which corresponds to the first connecting holes 221. The connecting vertical beam 22 also includes a connector, which passes through the first connecting holes 221 and the second connecting holes 211 in sequence to connect the first connecting vertical beam 21 and the second connecting vertical beam 22.

[0045] Since the first connecting holes 221 are spaced apart along the length of the second connecting vertical beam 22, when installing and connecting the first connecting vertical beam 21 and the second connecting vertical beam 22, the required length of the connecting vertical beam 2 can be calculated according to the actual situation, so that the second connecting hole 211 corresponds to different first connecting holes 221, and then the connecting vertical beam 2 can be adjusted to a suitable length by connecting it in sequence through the connectors to meet the needs of on-site construction.

[0046] Optionally, the second connecting vertical beam 22 may also include multiple beams of different lengths, so that different beams can be replaced according to the site conditions.

[0047] To further enhance the flexibility of adjusting the length of the connecting vertical beam 2, optionally, such as Figure 3 As shown, the connecting vertical beam 2 also includes a third connecting vertical beam 23. The two ends of the second connecting vertical beam 22 are connected to the first connecting vertical beam 21 and the third connecting vertical beam 23, respectively. The other end of the third connecting vertical beam 23 is connected to the hoisting beam 1. The second connecting vertical beam 22 has a plurality of third connecting holes 222 near the end of the third connecting vertical beam 23. These third connecting holes 222 are spaced apart along the length of the second connecting vertical beam 22. The third connecting vertical beam 23 has a fourth connecting hole 231 near the end of the second connecting vertical beam 22, corresponding to the third connecting holes 222.

[0048] By setting a third connecting vertical beam 23 between the second connecting vertical beam 22 and the hoisting beam 1, and setting a third connecting hole 222 on the second connecting vertical beam 22 and a fourth connecting hole 231 on the third connecting vertical beam 23, the length of the connecting vertical beam 2 can be adjusted according to the site conditions, so that the fourth connecting hole 231 connects with different third connecting holes 222. This configuration allows both ends of the second connecting vertical beam 22 to be adjusted to connect with the first connecting vertical beam 21 and the third connecting vertical beam 23 as needed, further improving the flexibility of adjustment to adapt to more situations.

[0049] To increase connection strength, optionally, such as Figure 3 As shown, multiple first connecting holes 221 and multiple third connecting holes 222 are spaced apart along the width direction of the second connecting vertical beam 22. Multiple second connecting holes 211 are spaced apart along the width direction of the first connecting vertical beam 21 and correspond one-to-one with the multiple first connecting holes 221. Multiple fourth connecting holes 231 are spaced apart along the width direction of the third connecting vertical beam 23 and correspond one-to-one with the multiple third connecting holes 222. Providing multiple connecting holes in the width direction and connecting them one-to-one with connectors increases the connection strength at the joints, thereby ensuring the strength of the adjusted connecting vertical beam 2.

[0050] Optionally, such as Figure 3As shown, the connecting vertical beam 2 may further include a connecting cylinder 24. One end of the first connecting vertical beam 21 and the third connecting vertical beam 23 are respectively inserted through both ends of the connecting cylinder 24. Each end of the connecting cylinder 24 has a fifth connecting hole 241, which corresponds to the third connecting hole 222 and the first connecting hole 221, respectively. Installing the connecting cylinder 24 at the second connecting vertical beam 22 can, on the one hand, strengthen the second connecting vertical beam 22 at the connection point, ensuring the overall strength of the connecting vertical beam 2; on the other hand, it can also protect the second connecting vertical beam 22 from damage during operation, extending its service life.

[0051] The connecting cylinder 24 can be a one-piece structure or an assembled structure. In one possible implementation, such as... Figure 3 As shown, the connecting cylinder 24 may include at least two connecting shells 242 that can be assembled with each other, and the corresponding positions of the two connecting shells 242 are respectively formed with fifth connecting holes 241. The connecting shells 242 can be assembled after being connected to the first connecting vertical beam 21 and the third connecting vertical beam 23 at both ends of the second connecting vertical beam 22, and then connected to the second connecting vertical beam 22 through the fifth connecting holes 241. Using the assembled connecting shells 242 can further reduce the difficulty of installation and improve the efficiency of construction.

[0052] Optionally, such as Figure 1 and Figure 2 As shown, the upper part of the hoisting beam 1 is provided with multiple hoisting holes 11, which are spaced apart along the length of the hoisting beam 1. Since there is an existing railway line in normal operation below the portal pier, the hoisting operation of the formwork can only be carried out on both sides of the railway line. The stress relationship of the formwork hoisting tool 100 will be different when the bottom formwork is installed at different positions. By setting multiple hoisting holes 11 along the length of the hoisting beam 1, different hoisting holes 11 can be used for hoisting according to the weight of the formwork and the different installation positions of the formwork, and the shape of the formwork hoisting tool 100 in the air can be adjusted to ensure the overall balance during hoisting.

[0053] 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.
