An assembled flexible connection device suitable for suspended track beams

Abstract

This invention discloses an assembled flexible connection device suitable for suspended track beams. It employs a height adjustment component and a horizontal adjustment component to detachably connect the Bailey bridge and the track beam, allowing both to be disassembled for reuse and avoiding waste. Simultaneously, when height and horizontal deviations occur during the lifting process, the height and horizontal positions of the track beam can be adjusted using the height adjustment component and the horizontal adjustment component, respectively, to ensure the structural stability of the track beam. Furthermore, a deformation buffer component is provided between the height adjustment component and the horizontal adjustment component to achieve a flexible connection between the track beam and the Bailey bridge. When deformation occurs during the lifting process of the Bailey bridge, the deformation buffer component undergoes elastic deformation to absorb the impact and vibration energy generated by the deformation of the Bailey bridge, thereby protecting the track beam from the deformation of the Bailey bridge and ensuring the track spacing and track shape, thus making the connection between the track beam and the Bailey bridge safe and reliable.

Description

Technical Field

[0001] This invention relates to the field of building engineering equipment technology, specifically to a connection device between a suspended track beam and a Bailey bridge. Background Technology

[0002] A building construction machine is a formwork integrated platform for high-rise concrete construction. The top platform of most building construction machines currently uses Bailey bridges as the main structural components. The track beam of the construction robot is usually hung below the Bailey bridge as the walking track of the suspended construction robot.

[0003] Currently, the track beams and Bailey bridges of suspended construction robots are connected by welding. This connection method results in the track beams and Bailey bridges being unusable, leading to waste. Furthermore, the track beams cannot be adjusted after welding, and any deviations in the track beams significantly impact later corrections. In addition, during the lifting process of the building construction robot, all hydraulic cylinders cannot be guaranteed to be completely synchronized, resulting in height or horizontal deviations at different positions of the Bailey bridge. Deformation of the Bailey bridge is transmitted to the track beams, affecting the spacing between track beams and their own shape, causing significant difficulties for the operation of the suspended robot.

[0004] To improve the reliability of the connection between the track beam and the Bailey bridge, Chinese Patent No. CN 206607685 U discloses a connector between the track beam and the Bailey bridge, including a fixed base, a screw, a positioning steel plate, and a steel pad. The screw is fixedly connected to the upper end of the fixed base, and the lower end of the fixed base is connected to the track beam. The positioning steel plate is fitted onto the screw and located above the fixed base. The steel pad is fitted onto the screw and placed on the channel steel of the lower chord of the Bailey bridge. A nut is fitted onto the screw to lock the steel pad onto the channel steel of the Bailey bridge. The steel pad is a perforated round steel plate.

[0005] However, although the connectors provided by the above solution increase the contact area between the connectors and the Bailey bridge, thereby improving the reliability of the connection between the track beam and the Bailey bridge, they cannot avoid the height and horizontal deviations of the track beam caused during the lifting process of the building machine, which affect the track spacing and track shape of the track beam.

[0006] Therefore, how to effectively adjust the height and horizontal deviations of the track beams while ensuring the reliability of the connection between the track beams and the Bailey bridge, and how to ensure the track spacing and track shape during the jacking process, has become an urgent problem to be solved in this field. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide a prefabricated flexible connection device suitable for suspended track beams that provides reliable connection, can adjust the deformation value generated during the lifting of the track beam, and ensures the track spacing and track shape.

[0008] To achieve the above objectives, the present invention provides an assembled flexible connection device suitable for suspended track beams, used in conjunction with a Bailey bridge, comprising:

[0009] A height adjustment assembly, detachably connected to the Bailey bridge frame and configured to be height-adjustable,

[0010] A deformation buffer assembly is disposed at the bottom of the height difference adjustment assembly and configured to undergo elastic deformation under stress.

[0011] A horizontal adjustment assembly is disposed at the bottom of the deformation buffer assembly and is detachably connected to the track beam, which can move horizontally and be fixed within the horizontal adjustment assembly.

[0012] Furthermore, the height adjustment assembly consists of a height adjustment bolt, a support stirrup, and a height adjustment base. The support stirrup is mounted on the lower chord of the Bailey bridge, and the height adjustment base is connected to the support stirrup via the height adjustment bolt.

[0013] Furthermore, the height adjustment base has a threaded groove that matches the height adjustment bolt, and the height adjustment bolt can rotate in the threaded groove to drive the height adjustment base to move vertically.

[0014] Furthermore, the level adjustment assembly includes a level adjustment box, in which a slider is housed, the slider being capable of moving horizontally within the level adjustment box.

[0015] Furthermore, the horizontal adjustment box is provided with horizontal adjustment bolts at both ends, the horizontal adjustment bolts are connected to the threaded holes at both ends of the horizontal adjustment box, and are connected to the slider through the threaded holes.

[0016] Furthermore, the horizontal adjustment box is provided with an observation hole for observing the slider.

[0017] Furthermore, the horizontal adjustment assembly also includes an adjustable connection device, which consists of a fixed slot and a movable slot. The fixed slot is connected to the slider, and the movable slot can move horizontally within the fixed slot and is detachably connected to the fixed slot.

[0018] Furthermore, the fixed slot and the movable slot are connected and fitted together to form a connecting groove that can accommodate the flange of the track beam.

[0019] The present invention provides an assembled flexible connection device for suspended track beams. It employs a height adjustment component and a horizontal adjustment component to detachably connect the Bailey bridge and the track beam, allowing both to be disassembled for reuse and avoiding waste. Simultaneously, when height and horizontal deviations occur during the lifting process, the height and horizontal positions of the track beam can be adjusted by the height adjustment component and the horizontal adjustment component respectively, ensuring the structural stability of the track beam. Furthermore, a deformation buffer component is provided between the height adjustment component and the horizontal adjustment component to achieve a flexible connection between the track beam and the Bailey bridge. When deformation occurs during the lifting process of the Bailey bridge, the deformation buffer component undergoes elastic deformation to absorb the impact and vibration energy generated by the deformation of the Bailey bridge, thereby protecting the track beam from the deformation of the Bailey bridge and ensuring the track spacing and track shape, thus making the connection between the track beam and the Bailey bridge safe and reliable.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0031] See Figure 1 The illustration shows an example of an assembled flexible connection device for suspended track beams provided by the present invention.

[0032] As shown in the figure, the prefabricated flexible connection device for suspended track beams in this example is used to cooperate with Bailey bridge 4 and mainly includes height adjustment component 1, deformation buffer component 2 and horizontal adjustment component 3.

[0033] The height adjustment component 1 is detachably connected to the Bailey bridge 4 and is configured to be height-adjustable. The deformation buffer component 2 is located at the bottom of the height adjustment component 1 and is configured to undergo elastic deformation under force. The horizontal adjustment component 3 is located at the bottom of the deformation buffer component 2 and is detachably connected to the track beam 5. The track beam 5 can move horizontally and be fixed in the horizontal adjustment component 3, so that the Bailey bridge 4 and the track beam 5 can be disassembled from the height adjustment component 1 and the horizontal adjustment component 3 respectively for reuse. Adjusting the height of the height adjustment component 1 and the horizontal movement of the track beam 5 in the horizontal adjustment component 3 can adjust the height and horizontal deviations generated during the lifting of the track beam. At the same time, the buffer deformation component 2 makes the track beam 5 and the Bailey bridge 4 flexibly connected. The elastic deformation of the buffer deformation component 2 can buffer and absorb the lifting deformation of the Bailey bridge 4, so that the track beam 5 is not affected by the deformation of the Bailey bridge. This ensures the stable connection between the track beam 5 and the Bailey bridge 4, while also ensuring the track spacing and track shape of the track beam 5.

[0034] Specifically, in combination Figure 2 and Figure 3 The height adjustment component 1 is mainly composed of a height adjustment bolt 11, a support stirrup 12 and a height adjustment base 13 connected together. The height adjustment bolt 11 can cooperate with the height adjustment base 13 to adjust the connection height between the height adjustment base 13 and the support stirrup 12, thereby adjusting the height of the height adjustment component 1 itself.

[0035] Furthermore, the supporting stirrup 12 includes a supporting top plate 121, a first vertical plate 122, and a second vertical plate 123. The first vertical plate 122 and the second vertical plate 123 are perpendicularly connected to the supporting top plate 121 at a distance, so that the supporting stirrup 12 is configured in a fork shape and is erected on the lower chord double channel steel 41 of the Bailey bridge 4. Specifically, the length of the supporting top plate 121 is configured to be greater than the distance between the lower chord double channel steel 41. The distance between the first vertical plate 122 and the second vertical plate 123 is preferably configured to match the distance between the lower chord double channel steel 41, so that when the two ends of the supporting top plate 121 are respectively erected on the lower chord double channel steel 41, the first vertical plate 122 and the second vertical plate 123 are located between the lower chord double channel steel 41 and respectively abut against the inner wall of the lower chord double channel steel 41, thereby fastening the supporting stirrup 12 to the Bailey bridge 4.

[0036] Meanwhile, since the supporting stirrups 12 are erected between the double channel steels 41 of the lower chord, the Bailey bridge 4 can be removed from the height adjustment assembly 1 by removing the supporting stirrups 12 from the double channel steels 41 of the lower chord, which is convenient for secondary use.

[0037] Correspondingly, the height adjustment base 13 is set at the bottom of the support stirrup 12, and is fixedly connected to the support stirrup 12 by the height adjustment bolt 11 to adjust the connection height.

[0038] Furthermore, the support top plate 121 of the support stirrup 12 is provided with a smooth round hole 1211 that matches the height adjustment bolt 11, and the height difference adjustment base 13 is formed with a threaded groove 131 that matches the height adjustment bolt 11, so that the height adjustment bolt 11 can pass through the smooth round hole 1211 on the support top plate 121 and be inserted into the threaded groove 131 of the height difference adjustment base 13, and be engaged with the threaded groove 131 through a threaded connection, thereby fixing the support stirrup 12 and the height difference adjustment base 13 together.

[0039] Meanwhile, since the height adjusting bolt 11 is threadedly engaged with the threaded groove 131, the rotation of the height adjusting bolt 11 in the threaded groove 131 can drive the height difference adjusting base 13 to move vertically, thereby adjusting the connection height between the height difference adjusting base 13 and the height adjusting bolt 11, and thus adjusting the height of the height difference adjusting component 1 itself, so that when a height deviation occurs during the lifting process of the track beam 5, the height of the track beam 5 can be adjusted through the height difference adjusting component 1.

[0040] In order to adjust the horizontal position of the track beam 5 when horizontal deviation occurs during the lifting process, the bottom of the height difference adjustment component 1 is provided with a horizontal adjustment component 3. The horizontal adjustment component 3 mainly includes a horizontal adjustment box 31 and an adjustable connecting device 32. The adjustable connecting device 32 is detachably connected to the track beam 5 and can move horizontally in the horizontal adjustment box 31 to adjust the horizontal position of the track beam 5.

[0041] Specifically, a sliding groove 311 is formed in the horizontal adjustment box 31, and a slider 312 is placed in the sliding groove 311. At the same time, horizontal adjustment bolts 313 are provided at both ends of the horizontal adjustment box 31. The horizontal adjustment bolts 313 are threadedly connected to the threaded holes 314 at both ends of the horizontal adjustment box 31, and are connected to the slider 312 through the threaded holes 314, so that the rotation of the horizontal adjustment bolts 313 in the threaded holes 314 can drive the slider 312 to move horizontally in the sliding groove 311.

[0042] Meanwhile, the horizontal adjustment box 31 is also provided with an observation hole 315 to view the horizontal movement status of the slider 312, thereby accurately adjusting the horizontal movement distance of the slider 312.

[0043] Furthermore, the bottom of the horizontal adjustment box 31 is provided with a slot 316 that communicates with the sliding groove 311, so that the adjustable connecting device 32 can be connected to the slider 312 through the slot 316. The slider 312 can move horizontally in the sliding groove 311, which can drive the adjustable connecting device 32 to move horizontally, thereby driving the track beam 5 to move horizontally and adjust the horizontal position.

[0044] In order to enable the adjustable connecting device 32 to be detachably connected to the track beam 5 and facilitate the secondary use of the track beam 5, the adjustable connecting device 32 is mainly composed of a fixed slot 321 and a movable slot 322 connected and cooperated.

[0045] Specifically, the fixed slot 321 includes a first fixed plate 3211 and a second fixed plate 3212 arranged at intervals. The ends of the first fixed plate 3211 and the second fixed plate 3212 are connected to the ends of the horizontal adjustment box 31 and gradually extend to the bottom of the horizontal adjustment box 31, and are connected to the slider 312, so that the fixed slot 321 is set at the bottom of the horizontal adjustment box 31 and fixedly connected to the slider 312. The horizontal movement of the slider 312 can drive the fixed slot 321 to move horizontally.

[0046] In conjunction with this, the movable slot 322 is preferably configured to match the spacing between the first fixed plate 3211 and the second fixed plate 3212, so that the movable slot 322 can be set between the first fixed plate 3211 and the second fixed plate 3212, abut against the first fixed plate 3211 and the second fixed plate 3212, and be fixedly connected by the fixing bolt 323.

[0047] Furthermore, the fixed slot 321 and the movable slot 322 are configured in a U-shaped structure to connect and cooperate to form a connecting groove 324 that can accommodate the flange 51 of the track beam 5, so that the track beam 5 can be inserted into the connecting groove 324 through the flange 51 and connected to the adjustable connecting device 32.

[0048] To ensure a secure connection between the track beam 5 and the adjustable connecting device 32, and to facilitate assembly and disassembly, the movable slot 322 is provided with an elongated hole 3221, and the first fixed plate 3211 is provided with a fixed hole 3213 corresponding to the elongated hole 3221. When the movable slot 322 is positioned between the first fixed plate 3211 and the second fixed plate 3212, the movable slot 322 can move horizontally between the first fixed plate 3211 and the second fixed plate 3212, thereby adjusting the length of the connecting groove 324 to match the flange 51 of the track beam 5. At this time, the fixed hole 3213 can correspond to any position in the elongated hole 3221, so that after the flange 51 is inserted into the connecting groove 324, the fixed slot 321 and the movable slot 322 are securely connected by the fixing bolt 323 passing through the fixed hole 3213 on the first fixed plate 3211 and the elongated hole 3221 on the movable slot 322, thereby fixing the track beam 5.

[0049] Furthermore, during disassembly, the track beam 5 can be separated from the adjustable connecting device 32 simply by removing the fixing bolts 323, making it easy to reuse.

[0050] Meanwhile, by rotating the horizontal adjusting bolts 313 at both ends of the horizontal adjustment box 31, the slider 312 can be driven to move horizontally in the sliding groove 311, thereby driving the fixed slot 321 to move horizontally, and driving the track beam 5 to move horizontally, so as to adjust the horizontal deviation generated during the lifting process of the track beam 5.

[0051] Therefore, the Bailey bridge 4 and the track beam 5 are detachably connected by the height difference adjustment component 1 and the horizontal difference adjustment component 3, respectively. The height deviation and horizontal deviation of the track beam 5 can be adjusted by the height difference adjustment component 1 and the horizontal difference adjustment component 3, respectively.

[0052] To prevent the deformation generated during the lifting of the Bailey bridge 4 from being transmitted to the track beam 5 and to ensure that the track spacing and track shape of the track beam 5 remain stable, a buffer deformation component 2 is provided between the height difference adjustment component 1 and the horizontal difference adjustment component 3 to achieve a flexible connection between the Bailey bridge 4 and the track beam 5.

[0053] Specifically, the buffer deformation component 2 is preferably composed of a high-strength spring, with one end connected to the height difference adjustment component 1 and the other end connected to the horizontal adjustment component 3. When the pressure generated by the deformation movement during the lifting of the Bailey bridge 4 is transmitted from the height difference adjustment component 1 to the buffer deformation component 2, the buffer deformation component 2 undergoes elastic deformation under force to absorb the energy such as impact and vibration generated by the deformation movement of the Bailey bridge 4, thereby buffering the deformation of the Bailey bridge 4 and isolating the deformation pressure from being transmitted to the track beam 5 by the horizontal adjustment component 3. This protects the track beam 5 from the deformation of the Bailey bridge 4 and ensures the track spacing and track shape.

[0054] The following examples illustrate the working process of this invention in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0055] Combination Figures 1 to 3 Taking the connection device provided by the present invention to connect the Bailey bridge 4 and the track beam 5 as an example.

[0056] First, the support stirrup 12 of the height difference adjustment assembly 1 is placed on the double channel steel 41 of the lower chord of the Bailey bridge 4. The height adjustment bolt 11 passes through the smooth round hole 1211 on the support stirrup 12 and is inserted into the threaded groove 131 of the height difference adjustment base 13, thus fixing the support stirrup 12 to the height difference adjustment base 13.

[0057] Therefore, this connecting device connects to the Bailey bridge 4. Next, the fixed slot 321 and the movable slot 322 of the horizontal adjustment component 3 are first separated. The flange 51 of the track beam 5 is inserted into the corresponding connecting slot 324 of the fixed slot 321. After abutting against the fixed slot 321, the movable slot 322 is set between the first fixed plate 3211 and the second fixed plate 3212 and moves horizontally between the first fixed plate 3211 and the second fixed plate 3212 to adjust the length of the connecting slot 324 to match the flange 51 of the track beam 5, so that the track beam 5 abuts against the fixed slot 321 and the movable slot 322 respectively.

[0058] Finally, the fixing bolt 323 is passed through the fixing hole 3213 on the first fixing plate 3211 and the elongated hole 3221 on the movable slot 322 to securely connect the fixing slot 321 and the movable slot 322, thereby fixing the track beam 5.

[0059] Furthermore, as the Bailey bridge 4 begins to lift, the track beam 5 is lifted via this connecting device. When the track beam 5 experiences a height deviation, the height adjusting bolt 11 is rotated to drive the height difference adjusting base 13 to move vertically, thereby adjusting the connection height between the height difference adjusting base 13 and the height adjusting bolt 11, adjusting the height of the height difference adjusting component 1 itself, and thus adjusting the height of the track beam 5.

[0060] Correspondingly, when the track beam 4 has a horizontal deviation, the horizontal adjustment bolts 313 at both ends of the rotating horizontal adjustment box 31 drive the slider 312 to move horizontally in the sliding groove 311, drive the fixed slot 321 to move horizontally, thereby driving the track beam 5 to move horizontally, so as to adjust the horizontal position of the track beam 5.

[0061] Meanwhile, when the Bailey bridge 4 deforms, the pressure generated by the deformation of the Bailey bridge 4 is transmitted from the height difference adjustment component 1 to the buffer deformation component 2. The buffer deformation component 2 undergoes elastic deformation under force to absorb the energy of impact and vibration generated by the deformation of the Bailey bridge 4, thereby buffering the deformation of the Bailey bridge 4. The pressure is then transmitted to the track beam 5 by the horizontal adjustment component 3, thus protecting the track beam 5 from the deformation of the Bailey bridge 4 and ensuring the track spacing and track shape.

[0062] After the Bailey bridge 4 and track beam 5 are no longer in use, the Bailey bridge 4 can be removed from the height adjustment assembly 1 by removing the support stirrup 12 from the lower chord double channel steel 41. The track beam 5 can be separated from the adjustable connection device 32 by removing the fixing bolt 323 from the fixing slot 321 and the movable slot 322. This facilitates the reuse of the Bailey bridge 4 and track beam 5 and avoids waste.

[0063] The present invention provides an assembled flexible connection device suitable for suspended track beams. It uses a height difference adjustment component 1 and a horizontal difference adjustment component 3 to connect with the Bailey bridge 4 and the track beam 5, which facilitates disassembly and avoids waste. At the same time, a deformation buffer component 2 is used in conjunction with the height difference adjustment component 1 and the horizontal difference adjustment component 3 to achieve a flexible connection between the Bailey bridge 4 and the track beam 5. This facilitates the adjustment of the height and horizontal deviation of the track beam 5, while buffering and absorbing the deformation of the Bailey bridge 4 to ensure the track spacing and track shape of the track beam 5.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
