Description

Technical Field

[0001] This utility model relates to the field of tower crane standard section connection technology, specifically, to a self-locking tower crane standard section connection structure. Background Technology

[0002] Tower crane standard sections are an important component of tower cranes. They provide a stable support structure, enabling the tower crane to remain stable at different heights and ensuring construction safety. Simultaneously, the standard sections transfer the weight, lifting load, and various loads of the tower crane to the foundation and the ground, ensuring the normal operation of the tower crane. During tower crane installation, installers need to splice multiple standard sections together. Traditionally, standard sections are connected using bolts. While this method ensures a strong and reliable connection between standard sections and can withstand large loads and external forces, it requires installing multiple bolts between two standard sections. This manual operation is time-consuming and labor-intensive, and in harsh weather conditions, the bolts are prone to corrosion, which reduces their strength and increases the risk of breakage. Furthermore, bolts are susceptible to breakage during subsequent disassembly. Therefore, we propose a self-locking tower crane standard section connection structure. Utility Model Content

[0003] The purpose of this utility model is to provide a self-locking tower crane standard section connection structure to solve the problems mentioned in the background art above:

[0004] 1. Traditional bolt connection operations are complex, time-consuming, and labor-intensive;

[0005] 2. Bolts are prone to corrosion and breakage when exposed to severe weather.

[0006] To achieve the above objectives, this utility model provides a self-locking tower crane standard section connection structure, including a lower pad plate, an upper pad plate on the upper side of the lower pad plate, a fixing component between the lower pad plate and the upper pad plate, the fixing component including a fixing block, the fixing block being fixedly disposed on the upper side of the lower pad plate, a wedge block being disposed inside the fixing block, a plurality of grooves for limiting the wedge block being formed on the inner wall of the fixing block, a first compression spring being symmetrically fixedly disposed between the top of the wedge block and the top of the fixing block, a groove matching the wedge block being formed on the top of the lower pad plate, and two first compression springs being disposed inside the groove.

[0007] As a further improvement to this technical solution, a connecting block is provided on the upper side of the fixing block, and a slot matching the wedge block is opened in the middle of the connecting block. The connecting block is fixedly installed on the lower side of the upper pad, and an inlet matching the connecting block is opened on one side of the fixing block.

[0008] As a further improvement to this technical solution, a stop block is provided on the lower side of the wedge block, and a slot for limiting the stop block is opened on the inner wall of the fixed block. One end of the stop block is rotatably disposed inside the slot. The stop block is disposed on the side of the wedge block near the entrance of the fixed block, and a second compression spring is fixedly disposed on the side of the stop block away from the entrance of the fixed block. The end of the second compression spring away from the stop block is fixedly connected to the inner wall of the fixed block.

[0009] As the connecting block slides into the interior of the fixed block, it gradually approaches the stop block and presses the stop block into the slot on one side to release the restriction on the wedge block. After part of the connecting block completely passes through the wedge block, the two No. 1 compression springs press the wedge block into the slot in the middle of the connecting block to fix the connecting block.

[0010] As a further improvement to this technical solution, a sliding groove is provided on the side of the lower pad near the entrance of the fixed block, and sliding rails are provided on both sides of the sliding groove that are far apart from each other. The two sliding rails are fixedly installed on the upper side of the lower pad, and slots matching the sliding rails are opened on both sides of the connecting block that are far apart from each other.

[0011] One end of the connecting block is limited by the slide groove and two slide rails. After the connecting block enters the slide groove, it quickly slides into the interior of the fixed block along the two slide rails.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this self-locking tower crane standard section connection structure, the user inserts the connecting block into the interior of the fixed block through the inlet at one end of the fixed block. As the connecting block slides into the fixed block, it gradually approaches the wedge block and passes through the underside of the wedge block. After the front half of the connecting block has completely passed through the underside of the wedge block, two No. 1 compression springs press the wedge block downward into the slot on the upper side of the connecting block. This device connects two standard sections through a self-locking structure. The operation is simple and quick, which speeds up the installation of tower crane standard sections. At the same time, it avoids the corrosion that is prone to occur in traditional bolt connections and improves the safety after the standard section is installed. Attached Figure Description

[0025] Example 1

[0026] Please see Figures 1-5As shown, this embodiment provides a self-locking tower crane standard section connection structure, including a lower pad plate 1, an upper pad plate 2 on the upper side of the lower pad plate 1, and multiple mounting holes at both ends of the lower pad plate 1 and the upper pad plate 2. When using this device, the user first installs the lower pad plate 1 and the upper pad plate 2 at corresponding positions on two tower crane standard sections. A fixing component 3 is provided between the lower pad plate 1 and the upper pad plate 2. The fixing component 3 includes a fixing block 31, which is fixedly installed on the upper side of the lower pad plate 1. A first positioning pin 6 is symmetrically fixedly installed on one end of the upper pad plate 2, and two first positioning pins 6 are installed on the lower side of the upper pad plate 2. A second positioning pin 7, matching the two first positioning pins 6, is symmetrically fixedly installed on one end of the fixing block 31. During connection... When using two standard sections, the user first inserts the two No. 1 positioning pins 6 into the two corresponding No. 2 positioning pins 7. A connecting block 34 is provided on the upper side of the fixing block 31. The connecting block 34 is fixedly set on the lower side of the upper pad 2. An entrance matching the connecting block 34 is opened on one side of the fixing block 31. A sliding groove is provided on the side of the lower pad 1 near the entrance of the fixing block 31. Slide rails 4 are provided on both sides of the sliding groove that are far apart from each other. The two slide rails 4 are fixedly set on the upper side of the lower pad 1. The slots matching the slide rails 4 are opened on both sides of the connecting block 34 that are far apart from each other. After inserting the two No. 1 positioning pins 6 into the two No. 2 positioning pins 7, one end of the connecting block 34 slides into the sliding groove at one end of the fixing block 31. Then the connecting block 34 slides along the two slide rails 4 into the interior of the fixing block 31.

[0027] Please see Figures 1-3As shown, a wedge-shaped block 32 is provided inside the fixing block 31, and a stop block 35 is provided on the lower side of the wedge-shaped block 32. A slot for limiting the stop block 35 is opened on the inner wall of the fixing block 31. One end of the stop block 35 is rotatably disposed inside the slot. The stop block 35 is disposed on the side of the wedge-shaped block 32 near the entrance of the fixing block 31. A second compression spring 36 is fixedly disposed on the side of the stop block 35 away from the entrance of the fixing block 31. The end of the second compression spring 36 away from the stop block 35 is fixedly connected to the inner wall of the fixing block 31. The stop block 35 is used to prevent the wedge-shaped block 32 from sliding downward. When the connecting block 34 slides into the fixing block 31, one end of the connecting block 34 gradually contacts the stop block 35 and presses the stop block 35 into the slot on one side. Then the connecting block 34 slides to the wedge-shaped block. The connecting block 34 passes under the wedge block 32 and gradually passes through it. The inner wall of the fixing block 31 has multiple grooves for limiting the wedge block 32. Two compression springs 33 are symmetrically fixed between the tops of the wedge block 32 and the fixing block 31. The top of the lower pad 1 has a slot matching the wedge block 32, and both compression springs 33 are located inside the slot. As the connecting block 34 passes under the wedge block 32, it gradually presses the wedge block 32 upwards into the slot on its upper side. A matching groove is formed in the middle of the connecting block 34. When one end of the connecting block 34 completely passes through it, the two compression springs 33 press the wedge block 32 into the groove in the middle of the connecting block 34, thus fixing the connecting block 34. (See also...) Figures 2-5 As shown, a detection component 5 is provided at the end of the fixed block 31 away from the slide rail 4. The detection component 5 includes a switch 51, which is fixedly installed at one end of the fixed block 31. A protrusion 52 corresponding to the position of the switch 51 is provided on the lower side of the upper pad 2. One end of the protrusion 52 is slidably installed inside the upper pad 2. A spring is fixedly installed between the protrusion 52 and the inner wall of the upper pad 2. The side of the protrusion 52 near the first positioning pin 6 is inclined. When the connecting block 34 slides into the fixed block 31, the protrusion 52 is pressed into the interior of the upper pad 2 by the fixed block 31. After the connecting block 34 is fixed, the protrusion 52 passes through the fixed block 31. On the upper side of the fixed block 31, the spring on the upper side of the protrusion 52 presses it downward. A sound alarm 53 and a laser alarm 54 are provided on the side of the switch 51 away from the fixed block 31. The sound alarm 53 and the laser alarm 54 are both fixedly installed on the upper side of the lower pad 1. The switch 51 is used to control the sound alarm 53 and the laser alarm 54 to work. When the connecting block 34 becomes loose, the connecting block 34 slides to the outside of the fixed block 31 and drives the protrusion 52 to slide closer to the switch 51. When the protrusion 52 contacts the switch 51, the sound alarm 53 and the laser alarm 54 immediately run and sound an alarm.

[0028] In practical use, the user first installs the lower pad 1 and upper pad 2 at the corresponding positions of the standard section. When connecting two standard sections, the user inserts the connecting block 34 into the interior of the fixing block 31 through the inlet at one end of the fixing block 31. As the connecting block 34 slides into the fixing block 31, it gradually approaches the wedge block 32 and passes through the underside of the wedge block 32. After the front half of the connecting block 34 has completely passed through the underside of the wedge block 32, the two compression springs 33 hold the wedge block 32 in place. 2. Press down into the slot on the upper side of the connecting block 34. When the device becomes loose, the connecting block 34 slides outward toward the fixing block 31 and drives the protrusion 52 to slide toward the side closer to the switch 51. When the protrusion 52 contacts the switch 51, the sound alarm 53 and the laser alarm 54 immediately sound an alarm. The device connects the two standard sections through a self-locking structure. The operation is simple and fast, which speeds up the installation of the tower crane standard sections. At the same time, it avoids the corrosion that is easy to occur in traditional bolt connections and improves the safety after the standard section is installed.
