Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a positioning type construction device for a steel-concrete composite beam bridge deck. Background Art

[0002] Reinforced concrete prefabricated bridge panels are widely used in China. During the construction of prefabricated bridge panels, the prefabricated bridge panels are transported along the track system to the bottom of the lifting device of the lifting frame by a pallet truck. The bridge panels are hoisted by the hoist on the lifting mechanism, and then the pallet truck moves back to transport the bridge panels. The lifting mechanism lowers the hoist and the bridge panels so that the bridge panels are laid in the preset position. The hoisting of the bridge panels usually requires pre-embedded lifting rings on the bridge panels, and the bridge panels are lifted or lowered by hanging the hooks on the hoist. However, the construction cost of this lifting method is relatively high.

[0003] In this regard, the invention patent with publication number CN119195000A in the prior art provides a construction device for prefabricated bridge decks made of steel-concrete composite beams and an application method thereof. The lifting device and the bridge deck are lifted by aligning the lifting rod and extending it into the lifting hole, and multiple lifting blocks are engaged with the annular limit holes reserved on the inner wall of the lifting hole of the bridge deck. There is no need to pre-embed multiple lifting rings on the bridge deck for lifting the bridge deck, and the lifting device can be reused, which reduces construction costs.

[0004] In the existing technology, during the construction process, the hanger needs to be completely aligned with the lifting hole to achieve the connection and lifting of the hanger to the bridge deck. If the hanger deviates slightly from the lifting hole, the connection effect between the hanger and the bridge deck cannot be achieved. The position of the hanger needs to be repeatedly corrected to achieve the docking of the hanger and the bridge deck. The repeated positioning steps make the bridge deck transportation process inefficient. Summary of the Invention

[0021] The distance from one end of the arc-shaped slot to the center of the disc is greater than the distance from the other end to the center of the disc;

[0022] The arc groove is driven to move relative to the slide buckle by rotating the disc, so that the slide buckle moves along the arc groove to the end farther from the center of the disc, thereby driving the movable bolt and the positioning cylinder to move outward along the movable groove and abut against the inner wall of the movable cavity.

[0023] Furthermore, a plurality of connecting slots are connected in the mounting sleeve, the connecting slots are away from the movable slot, and the disc is rotatably arranged in the connecting slots;

[0033] The driving motor drives the threaded column to spirally rise in the internal threaded section through the second clamping rod and the first clamping rod, and pulls the lifting block to rise through the limiting column and the pull rope. The rising action of the lifting block drives the clamping block to be clamped in the clamping slot, and at the same time drives the disc to rotate and drives the positioning cylinder to move outward through the limiting cylinder. When the threaded column spirally rises and disengages from the internal threaded section, the threaded column stops rising and continues to rotate to drive the limiting cylinder to maintain a rotating state and drive the positioning cylinder to continue to move outward and abut against the inner wall of the movable cavity.

After the positioning is completed, the relative position between the movable clamping column and the hanging column is fixed by the positioning structure. The positioning of the clamping block and the clamping slot body can be achieved without the need for the hanging column to be completely aligned with the hanging hole, which simplifies the connection process between the bridge panel and the hanging column and optimizes the efficiency of the bridge panel transportation process.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the present invention provides a positioning construction equipment for steel-concrete composite beam bridge deck, including a lifting frame 2 installed on a lifting frame 1, a hanging column 3 is installed on each lifting frame 2, a movable clamping column 4 is movably installed on the bottom of the hanging column 3, and a plurality of clamping blocks 5 are arranged in a circular array on the bottom of the movable clamping column 4. The lifting frame 1 generally refers to a lifting equipment, and the lifting frame 2 is usually arranged in two groups. A plurality of hanging columns 3 are also arranged on each lifting frame 2, and the specific number is determined according to the number of lifting holes on the bridge deck.

[0052] The hanging column 3 can be extended into the hanging hole reserved in the bridge deck, and the clamping block 5 is engaged with the clamping groove in the hanging hole.

[0053] A mounting sleeve 6 is provided at the bottom of the hanging column 3, and a movable cavity 7 is formed in the top of the movable clamping column 4. The mounting sleeve 6 is movably assembled in the movable cavity 7, so that the movable clamping column 4 can move in a direction perpendicular to the length of the hanging column 3. When the movable clamping column 4 is calibrated relative to the clamping slot and the hanging hole, the mounting sleeve 6 and the movable cavity 7 also undergo relative movement.

[0054] An integrated driving member 8 is provided in the hanging column 3. The integrated driving member 8 can synchronously push the clamping blocks 5 to move outward along the radial direction of the movable clamping column 4. When at least one of the clamping blocks 5 moves outward to contact the inner wall of the clamping slot, the inner wall of the clamping slot exerts a reaction force and causes the movable clamping column 4 to adjust its position relative to the clamping slot until all the clamping blocks 5 contact and are positioned on the inner wall of the clamping slot.

[0055] Among them, a positioning structure 9 is provided in the mounting sleeve 6, and the positioning structure 9 can be pressed against the movable cavity 7 under the drive of the integrated driving component 8 to position the mounting sleeve 6 and the movable cavity 7, so that the relative position between the movable clamping column 4 and the hanging column 3 is fixed after the clamping block 5 completes the cooperation with the clamping slot.

[0056] In the present invention, the hanging column 3 is roughly aligned with the position of the hanging hole. During the outward movement of the clamping block 5, when at least one of the clamping blocks 5 first contacts the inner wall of the clamping slot, the inner wall of the clamping slot applies a reaction force to adjust the position of the movable clamping column 4 relative to the clamping slot until all the clamping blocks 5 are positioned on the inner wall of the clamping slot. After the positioning is completed, the relative position between the movable clamping column 4 and the hanging column 3 is fixed by the positioning structure 9. The positioning of the clamping block 5 and the clamping slot can be achieved without the hanging column 3 being completely aligned with the hanging hole, which simplifies the connection process between the bridge panel and the hanging column 3 and optimizes the efficiency of the bridge panel transportation process.

[0057] In the present invention, the radius of the hanging column 3 is smaller than the radius of the hanging hole. Therefore, in the process of aligning the hanging column 3 with the hanging hole, it is sufficient to align it in a rough position so that the hanging column 3 can enter the hanging hole. It does not need to be completely aligned. In order to ensure the positioning effect of the clamping block 5 and the clamping slot, the radius of the clamping slot is larger than the radius of the hanging hole. After the clamping block 5 is clamped into the clamping slot, it can no longer slide out of the hanging hole.

[0058] In the present invention, the block 5 can move outward along the radial direction of the movable clamping column 4. The block 5 is generally provided in a plurality of pieces. In order to realize the synchronous outward movement of the block 5, the present invention makes the following design, such as Figure 6 and Figure 8 As shown, a mounting cavity 10 is formed in the movable clamping column 4, and a sliding hole 11 is provided on the side wall of the movable clamping column 4, and the clamping block 5 is slidably arranged in the sliding hole 11;

[0059] A lifting block 12 is provided at the center position of the installation cavity 10, and an inclined groove 13 is provided on the lifting block 12. A wedge block 14 is provided at the end of the clamping block 5. The width of the opening of the inclined groove 13 is smaller than the width of its bottom. The design of the inclined groove 13 ensures that the wedge block 14 is always in the inclined groove 13 within a certain sliding stroke and will not leave the inclined groove 13.

[0060] The wedge block 14 cooperates with the inclined groove 13 and slides in the inclined groove 13, and the end of the clamping block 5 passes through the opening of the inclined groove 13;

[0061] The lifting block 12 is pulled to move the wedge block 14 along the inclined groove 13 , so that the clamping block 5 moves outward along the sliding hole 11 .

[0062] In the above embodiment, the lifting block 12 needs to be driven to rise in order to realize the synchronous outward movement of the card block 5. Specifically, the lifting block 12 is driven to rise by the integrated driving component 8, and the inclined groove 13 will rise together with the lifting block 12. During the rising process, the movement of the inclined groove 13 will prompt the wedge block 14 to move outward, thereby driving the card block 5 to move outward, and the outward movement distance of each card block 5 is consistent.

[0063] By designing the inclination of the inclined groove 13, the smaller the inclination of the inclined groove 13, the larger its span in the horizontal direction, and the greater the outward displacement of the blocking block 5 during its upward movement. Therefore, the inclination of the inclined groove 13 is designed accordingly according to the specific size of the blocking slot body.

[0064] The lifting block 12 can move up under the drive of the integrated driving member 8, and can also move down automatically to ensure that the lifting block 12 and the card block 5 can automatically reset without the action of external force. Specifically, Figure 6 As shown, an annular plate 15 is provided in the installation cavity 10, a sleeve 16 is provided at the bottom of the annular plate 15, a telescopic column 17 is movably provided in the sleeve 16, and the end of the telescopic column 17 is connected to the lifting block 12; a first spring is provided between the telescopic column 17 and the sleeve 16.

[0065] The lifting block 12 can move upward under the drive of the integrated driving member 8. After moving upward, in the absence of other external forces, the elastic force of the first spring can push the telescopic column 17 to reset, thereby prompting the lifting block 12 to reset.

[0066] In the present invention, the positioning structure 9 can be driven by the integrated driving member 8 to abut against the movable cavity 7 to position the mounting sleeve 6 and the movable cavity 7, so that the relative position between the movable clamping column 4 and the hanging column 3 is fixed after the clamping block 5 completes the engagement with the clamping slot. Specifically, Figure 6 and Figure 7As shown, the mounting sleeve 6 is annular, and the positioning structure 9 includes a disc 91 disposed in the mounting sleeve 6 and a sliding buckle 92 movably disposed on the disc 91;

[0067] The disc 91 is provided with an arcuate groove 93, in which a sliding buckle 92 slides. A movable bolt 94 is connected to the sliding buckle 92. A positioning cylinder 95 is sleeved on the end of the movable bolt 94. A second spring is provided between the positioning cylinder 95 and the movable bolt 94. A movable groove 96 for the positioning cylinder 95 to pass through is provided on the mounting sleeve 6. The positioning cylinder 95 is directly opposite to the movable cavity 7.

[0068] The distance between one end of the arc-shaped slot 93 and the center of the disk 91 is greater than the distance between the other end and the center of the disk 91;

[0069] Among them, by rotating the disc 91, the arc groove 93 is driven to move relative to the slide buckle 92, so that the slide buckle 92 moves along the arc groove 93 to the end farther away from the center of the disc 91, thereby driving the movable bolt 94 and the positioning cylinder 95 to move outward along the movable groove 96 and abut against the inner wall of the movable cavity 7.

[0070] When the disc 91 is driven to rotate, the arc groove 93 will be driven to rotate, so that the slider 92 moves relatively in the arc groove 93. The end of the arc groove 93 farther from the center of the disc 91 gradually rotates to approach the slider 92. During this process, the slider 92 moves outward along the arc groove 93, that is, it moves outward along the radius of the disc 91, thereby driving the movable bolt 94 and the positioning cylinder 95 to move outward along the direction of the movable groove 96. The above process is mainly the process of driving the positioning cylinder 95 outward by driving the disc 91 to rotate and gradually resting against the inner wall of the movable cavity 7.

[0071] Since the movable clamping column 4 may deviate from the central axis of the suspension column 3 during the calibration process, in this case, the outer end of the positioning cylinder 95 will definitely not contact the inner wall of the movable cavity 7 at the same time during the outward movement. The main purpose of the positioning cylinder 95 is to increase the movable resistance between the movable cavity 7 and the mounting sleeve 6, so that the movable clamping column 4 no longer moves relative to the suspension column 3 after the calibration is completed. Therefore, the design of the second spring between the positioning cylinder 95 and the movable bolt 94 can ensure that all the positioning cylinders 95 can contact the inner wall of the movable cavity 7, thereby ensuring the positioning effect between the positioning cylinder 95 and the movable cavity 7.

[0072] In the above embodiment, the disc 91 rotates relative to the mounting sleeve 6. Therefore, a plurality of connecting slots 97 are connected in the mounting sleeve 6. The connecting slots 97 are away from the movable slots 96, and the disc 91 is rotatably arranged in the connecting slots 97. The top of the connecting slot 97 is connected to the bottom of the suspension column 3 through the connecting block 98, ensuring that the connecting slot 97 and the mounting sleeve 6 are both in a state of being installed and connected with the suspension column 3.

[0073] Among them, the mounting sleeve 6 is movably assembled in the movable cavity 7, and the positioning cylinder 95 is also in contact with and positioned on the inner wall of the movable cavity 7. In order to avoid the positioning cylinder 95 directly contacting the inner wall of the movable cavity 7 at the beginning of its movement, which causes the movable clamping column 4 to be directly fixed, the present invention divides the movable cavity 7 into zones. Specifically, Figure 7 As shown, the movable cavity 7 includes an inner ring cavity 71 and an outer ring cavity 72 , the mounting sleeve 6 moves in the inner ring cavity 71 , and the positioning cylinder 95 is opposite to the outer ring cavity 72 ;

[0074] The height of the outer ring cavity 72 is consistent with the thickness of the mounting sleeve 6 , and the height of the inner ring cavity 71 is consistent with the diameter of the positioning cylinder 95 .

[0075] No matter how much the movable clamping column 4 deviates from the central axis of the suspension column 3, the mounting sleeve 6 is located in the inner ring cavity 71, and it is necessary to ensure that the mounting sleeve 6 does not separate from the inner ring cavity 71. To this end, the inner diameter of the inner ring cavity 71 needs to be smaller than the outer diameter of the mounting sleeve 6.

[0076] In the present invention, the integrated driving component 8 can synchronously push the blocking block 5 to move outward along the radial direction of the movable blocking column 4. When at least one of the blocking blocks 5 moves outward to contact the inner wall of the blocking groove body, the inner wall of the blocking groove body applies a reaction force and adjusts the position of the movable blocking column 4 relative to the blocking groove body until all the blocking blocks 5 are in contact with and positioned on the inner wall of the blocking groove body. Specifically, the integrated driving component 8 includes a pull rope 81 connected to the lifting block 12, and the pull rope 81 passes through the annular plate 15.

[0077] By pulling the pull rope 81 , the lifting block 12 can be driven to move upward.

[0078] In the present invention, not only can the purpose of pulling the pull rope 81 upward be achieved, but also the purpose of driving the disc 91 to rotate can be achieved. To this end, the integrated driving member 8 also includes the following structure: a limiting cylinder 82 is provided on the disc 91. The limiting cylinder 82 is in the shape of a rectangular parallelepiped. A limiting post 83 is movably provided in the limiting cylinder 82. The limiting post 83 fits inside the limiting cylinder 82, passes through the disc 91, and is connected to the end of the pull rope 81.

[0079] The end of the limiting column 83 is connected to a threaded column 84, and the end of the threaded column 84 is provided with a first clamping rod 85. A driving motor is provided in the hanging column 3, and the driving end of the driving motor is connected to a second clamping rod 86. The first clamping rod 85 is arc-shaped and cooperates with each other in the circumferential direction and is slidably connected;

[0080] A mounting tube 87 is connected to the inside of the hanging column 3 , and an internal thread section 88 is formed at the bottom of the threaded column 84 , and the threaded column 84 is threadedly matched with the internal thread section 88 .

[0081] Driven by the driving motor, the threaded column 84 can be driven to rotate through the second clamping rod 86 and the first clamping rod 85. When the threaded column 84 rotates, the threaded column 84 spirally rises in the internal thread section 88, and the lifting block 12 is pulled up by the limiting column 83 and the pull rope 81. The rising action of the lifting block 12 drives the clamping block 5 to be clamped in the clamping slot. In the process of spiral rising, the above threaded column 84 can also drive the first clamping rod 85 to rise, and the first clamping rod 85 slides upward along the direction of the second clamping rod 86. The first clamping rod 85 and the second clamping rod 86 always maintain a coordinated state during the relative movement. In this coordinated state, the rotation of the second clamping rod 86 can drive the first clamping rod 85 to rotate.

[0082] Since the outward positioning effect of the positioning cylinder 95 in the present invention is produced after the clamping block 5 is positioned, it is necessary to drive the disc 91 to continue to rotate a certain angle after the lifting block 12 is raised. In this regard, the present invention is further designed to form a smooth section 89 in the threaded column 84, and the smooth section 89 is connected to the internal threaded section 88;

[0083] The driving motor drives the threaded column 84 to spirally rise in the internal thread section 88 through the second clamping rod 86 and the first clamping rod 85, and pulls the lifting block 12 to rise through the limiting column 83 and the pull rope 81. The rising action of the lifting block 12 drives the clamping block 5 to be clamped in the clamping groove body, and at the same time drives the disc 91 to rotate and drives the positioning cylinder 95 to move outward through the limiting cylinder 82. When the threaded column 84 spirally rises and disengages from the internal thread section 88, the threaded column 84 stops rising and continues to rotate to drive the limiting cylinder 82 to maintain a rotating state and drive the positioning cylinder 95 to continue to move outward and rest against the inner wall of the movable cavity 7.

[0084] The continuous rotation of the threaded column 84 can drive the limiting cylinder 82 to maintain the rotating state and drive the positioning cylinder 95 to continue to move outward and abut against the inner wall of the movable cavity 7, thereby realizing the positioning between the positioning cylinder 95 and the movable cavity 7.

[0085] In summary, the main implementation process of the present invention is:

[0086] Transport the bridge deck to the bottom of the crane 1 by a transport vehicle, and align the suspending posts 3 roughly with the lifting holes;

[0087] The lifting equipment on the lifting frame 1 drives the lifting frame 2 to descend, and the davit 3 extends into the lifting hole;

[0088] The drive motor is started, and the drive motor can drive the threaded column 84 to rotate through the second clamping rod 86 and the first clamping rod 85. When the threaded column 84 rotates, the threaded column 84 spirally rises in the internal thread section 88, and the lifting block 12 is pulled up through the limiting column 83 and the pull rope 81. The rising action of the lifting block 12 drives the clamping blocks 5 to gradually move outward. When at least one of the clamping blocks 5 moves outward to contact the inner wall of the clamping slot, the inner wall of the clamping slot exerts a reaction force and causes the movable clamping column 4 to adjust its position relative to the clamping slot until all the clamping blocks 5 contact and are positioned on the inner wall of the clamping slot, and the clamping blocks 5 are completely locked.

[0089] At the same time, the rotation of the limiting column 83 also drives the limiting cylinder 82 to rotate, and the limiting cylinder 82 drives the disc 91 to rotate and drives the positioning cylinder 95 to move outward. When the threaded column 84 spirally rises to disengage from the internal threaded section 88, the threaded column 84 stops rising, and the clamping block 5 completes the clamping position. The threaded column 84 disengages from the internal threaded section 88 and enters the smooth section 89. The threaded column 84 can continue to rotate, but no longer rises. The continuous rotation of the threaded column 84 can drive the limiting cylinder 82 to maintain the rotating state and drive the positioning cylinder 95 to continue to move outward and abut against the inner wall of the movable cavity 7, thereby realizing the positioning between the positioning cylinder 95 and the movable cavity 7, and the relative position between the movable clamping column 4 and the suspension column 3 is fixed;

[0090] At this time, the clamping block 5 has been assembled with the clamping slot in the lifting hole, and the relative position between the movable clamping column 4 and the hanging column 3 is fixed. Start the lifting frame 1 to drive the bridge deck at the bottom of the lifting frame 2 to the installation position, and lower the bridge deck to the installation position through the lifting frame 2. Start the driving motor in reverse to release the limit between the movable clamping column 4 and the hanging column 3 and drive the clamping block 5 back to the movable clamping column 4, so that the hanging column 3 is separated from the lifting hole and the movable clamping column 4 is separated from the clamping slot.
