Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a working platform for installing and dismantling the inner sliding beam hanger of a continuous beam. Background Technology

[0002] The sliding beam is used to support the weight of the inner and outer molds and the top plate. The sliding beam is divided into an outer sliding beam outside the web, an inner sliding beam inside the box girder cavity, and a guide beam located outside the web. A working platform is arranged on the inner sliding beam for the installation and disassembly of the inner sliding beam and for construction of internal components of the box girder. However, the existing working platform is fitted onto the inner sliding beam by welding multiple steel plates to form a rectangular frame (or by using bolts to detachably connect multiple steel plates). The position of the working platform can be changed by sliding the rectangular frame on the inner sliding beam. However, the inner sliding beam is suspended from the top plate of the continuous beam by a hanger anchored to the top plate. The hanger will prevent the rectangular frame from moving further and limit its sliding position. Therefore, a working platform needs to be arranged on both sides of the hanger. This further compresses the internal space of the continuous beam, making the space available for other work smaller and inconvenient for the placement of other equipment and the construction of workers. At the same time, regardless of whether the working platform has a detachable rectangular frame or a welded rectangular frame, the rectangular frame needs to be cut or bolted off during disassembly, which is quite cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a working platform for installing and dismantling the sliding beam hanger in a continuous beam, so as to solve the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a working platform for installing and dismantling the inner sliding beam suspension rod of a continuous beam, comprising an inner sliding beam, a movable platform provided on one side of the inner sliding beam, the movable platform being suspended on the inner sliding beam by a rectangular frame assembly, the rectangular frame assembly comprising a first U-shaped frame and a second U-shaped frame, a second sliding groove being provided in one end of the first U-shaped frame, a slider being slidably disposed in the second sliding groove, two elastic grippers being fixedly connected to the top of the slider, a rotatably disposed swing rod being connected to the slider by a torsion spring, a guide locking assembly being fixedly connected to the inner side wall of the second sliding groove, the end of the first U-shaped frame being inserted between the two elastic grippers and pushing the slider, causing the swing rod to engage in the guide locking assembly to achieve a locking connection between the first U-shaped frame and the second U-shaped frame.

[0005] Furthermore, a wedge block is fixedly connected to the side of the second U-shaped frame near the first U-shaped frame. The wedge block is inserted between the two elastic grippers and pushes the slider.

[0006] Furthermore, the guide locking assembly includes an upper limit block and a lower limit block. The bottom of the upper limit block has a snap-fit ​​groove, and the top of the lower limit block has a guide groove. The distance between the upper limit block and the lower limit block forms a sliding groove for the vertical rod at the end of the swing arm to pass through.

[0007] Furthermore, the slider is connected to the bottom of the second groove by a spring.

[0008] Furthermore, an enlarged groove is provided at the outlet position of the second chute.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0018] Please see Figures 1-7 A working platform for installing and dismantling the inner sliding beam suspension rod of a continuous beam includes an inner sliding beam 1. A movable platform 2 is provided on one side of the inner sliding beam 1. The movable platform 2 is suspended on the inner sliding beam 1 by a rectangular frame assembly. The rectangular frame assembly includes a first U-shaped frame 31 and a second U-shaped frame 32. A second sliding groove 312 is opened in one end of the first U-shaped frame 31. A slider 7 is slidably arranged in the second sliding groove 312. Two elastic grippers 5 are fixedly connected to the top of the slider 7. A swing rod 8 is rotatably connected to the slider 7 by a torsion spring. A guide locking assembly 9 is fixedly connected to the inner side wall of the second sliding groove 312. By inserting the end of the first U-shaped frame 31 between the two elastic grippers 5 and pushing the slider 7, the swing rod 8 is locked into the guide locking assembly 9 to achieve a locking connection between the first U-shaped frame 31 and the second U-shaped frame 32.

[0019] Specifically, the assembly of the rectangular frame assembly is completed by locking the first U-shaped frame 31 and the second U-shaped frame 32, and the mobile platform 2 is hoisted on the inner sliding beam 1. The bottom of the platform 2 is covered with a partition plate 21. The top of the inner sliding beam 1 is hoisted by the hanger 4 anchored to the top plate of the continuous beam.

[0020] This invention replaces the rectangular frame with a rectangular frame assembly, and uses the quick disassembly of the rectangular frame assembly to replace the traditional disassembly method of cutting steel plates or removing bolts, which greatly improves the installation and disassembly efficiency of the mobile platform 2. It reduces the number of mobile platforms that should appear in the continuous beam to one or two, which can further expand the movable space in the cavity of the continuous beam and facilitate construction by workers.

[0021] Furthermore, a wedge block 6 is fixedly connected to the side of the second U-shaped frame 32 near the first U-shaped frame 31. The wedge block 6 is inserted between the two elastic grippers 5 and pushes the slider 7. The elastic grippers 5 are made of elastic metal and are fixedly connected to the top of the slider 7. When the wedge block 6 is inserted between the two elastic grippers 5, it squeezes the slider 7, causing the slider 7 to overcome the elastic force of the spring 10 and slide into the second slide groove 312. This causes the two elastic grippers 5 to deform and move closer to each other due to the restriction of the inner wall of the second slide groove 312, thereby wrapping around the wedge block 6 and achieving the limiting between the wedge block 6 and the groove on the inner side of the elastic gripper 5, thus locking the wedge block 6.

[0022] Furthermore, the guide locking assembly 9 includes an upper limit block 91 and a lower limit block 92. The bottom of the upper limit block 91 is provided with a snap-fit ​​groove 911, and the top of the lower limit block 92 is provided with a guide groove 921. The distance between the upper limit block 91 and the lower limit block 92 forms a sliding groove for the vertical rod at the end of the swing arm 8 to pass through. The slider 7 is connected to the bottom of the second sliding groove 312 by a spring 10. The outlet position of the second sliding groove 312 is provided with an enlarged hole groove.

[0023] Specifically, the rocker arm 8 has vertical rods on both sides. One vertical rod is rotatably mounted on the slider 7, and a torsion spring is sleeved on the vertical rod. One end of the torsion spring is inserted into the rocker arm 8, and the other end is inserted into the slider 7. When the rocker arm 8 rotates, it will be subjected to the torque force of the torsion spring. Then, when the wedge block 6 presses the slider 7, causing the slider 7 to slide into the second slide groove 312, the rocker arm 8 abuts against the top surface of the upper limit block 91, and then rotates after overcoming the torque force of the torsion spring. The bottom of the rocker arm 8 slides along the top surface of the upper limit block 91. After the rocker arm 8 is separated from the top surface of the upper limit block 91, under the action of the torque force of the torsion spring, the rocker arm 8 swings, causing the vertical rod on the rocker arm 8 to engage in the locking groove 911, thus locking the slider 7 and the first U-shaped frame 31. At the same time, under the limiting action of the expansion groove on the front side of the second slide groove 312, the two elastic grippers 5 move closer to each other, causing the two elastic grippers to engage in the locking groove 911. 5. The wedge block 6 is completely clamped and limited. Here, the upper limit block 91 and the lower limit block 92 are both fixedly connected to the inner wall of the second slide groove 312. When unlocking is required, the wedge block 6 is pushed to continue to squeeze the slider 7, so that the slider 7 continues to slide into the second slide groove 312 against the elastic force of the spring 10. The slider 7 then abuts against the bottom of the inner wall of the second slide groove 312, so that the vertical rod of the swing arm 8 is disengaged from the locking groove 911. Then, the force of pressing the second U-shaped frame 32 is released. The torque force of the torsion spring, combined with the elastic force of the spring 10, makes the vertical rod of the swing arm 8 slide along the slide groove formed by the locking groove 911 and the guide groove 921, and finally disengage from the guide locking assembly 9, thereby releasing the locking relationship between the vertical rod of the swing arm 8 and the guide locking assembly 9. At the same time, the elastic claw 5 slides out of the enlarged slot, so that the two elastic claws 5 no longer clamp the wedge block 6 and contact the locking relationship between the first U-shaped frame 31 and the second U-shaped frame 32.

[0024] Furthermore, a first sliding groove 311 is provided on the other end of the first U-shaped frame 31, and an insert 61 is fixedly connected to the other end of the second U-shaped frame 32. The insert 61 can be inserted into the first sliding groove 311.

[0025] Specifically, when the wedge block 6 and the elastic gripper 5 lock together, the insert block 61 is also inserted into the first slide groove 311 to enhance the locking stability of the first U-shaped frame 31 and the second U-shaped frame 32.

[0026] Furthermore, L-shaped frames 321 are fixedly connected to the inner sides of both ends of the second U-shaped frame 32.

[0027] Specifically, when the first U-shaped frame 31 and the second U-shaped frame 32 are locked, the vertical section of the L-shaped frame 321 fits against the side of the inner sliding beam 1, and the L-shaped frame 321 is fixedly connected to the second U-shaped frame 32 by screws.

[0028] In this utility model, reference Figures 1 to 4First, the mobile platform 2, with the first U-shaped frame 31 welded on it, is mounted on the inner slide beam 1. Then, the insert block 61 is aligned with the first slide groove 311, and the wedge block 6 is aligned between the two elastic grippers 5. The second U-shaped frame 32 is pressed, causing the insert block 61 to slide into the first slide groove 311. The wedge block 6 presses the slider 7, causing the slider 7 to overcome the elastic force of the spring 10 and engage the vertical rod at the bottom of the swing arm 8 into the guide locking assembly 9, thus locking the slider 7 with the first U-shaped frame 31. At the same time, the two elastic grippers 5 clamp the wedge block 6, thus locking the second U-shaped frame 32 with the first U-shaped frame 31, completing the installation of the mobile platform 2. When disassembly is required, the second U-shaped frame 32 is briefly pressed, and the wedge block 6 will pop out of the second slide groove 312, releasing the lock between the first U-shaped frame 31 and the second U-shaped frame 32.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
