Description

Technical Field

[0001] This invention relates to the field of tower crane protection technology, and in particular to a horizontal protection device for socket-type tower cranes. Background Technology

[0002] In modern construction, tower cranes, as core vertical and horizontal transportation equipment, are of paramount importance for operational safety. To ensure the safety of the tower crane foundation and the operating area at its base, and to prevent falling objects or ground debris from entering the foundation and affecting equipment operation, construction specifications require horizontal protection at the base of the tower crane. Therefore, a safe, reliable, and economical tower crane horizontal protection device is of great significance for ensuring construction safety and improving project efficiency.

[0003] Currently, in conventional construction projects, the horizontal protection of tower cranes commonly employs traditional woodworking formwork techniques. Specifically, construction workers use wooden planks as the main protective material in the open area where the embedded parts of the tower crane base contact the ground, and then use wooden beams for horizontal support at the bottom, forming an isolation layer to prevent debris from entering. Simultaneously, to secure and connect the protective panels, simple metal edging or angle irons are usually installed along the edges of the planks, and temporary fixation is achieved using bolts or welding, thus constructing a horizontal protective platform surrounding the standard section of the tower crane.

[0004] However, the most prominent problem with traditional tower crane horizontal protection is that its overall structure cannot be reused multiple times. Because wooden planks and timber are easily damaged during dismantling, and are accelerated to decay and deformation by factors such as rain and sun exposure in the site environment, most of the protective materials cannot be reused in new tower crane foundations after each construction section or project is completed. This not only results in significant material waste and increased transportation costs, but also requires construction workers to frequently re-cut, re-install, and re-materials, severely impacting construction efficiency and economic benefits. Therefore, this application proposes a socket-type tower crane horizontal protection device. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art that the overall structure cannot be reused multiple times, and to propose a horizontal protection device for socket tower cranes.

[0006] The technical solution of the present invention: A horizontal protection device for a socket-type tower crane, comprising multiple PC endurance boards, and further comprising: Multiple connecting frames are respectively installed on the outer wall of multiple PC endurance boards; A connection adjustment mechanism is provided between multiple connection frames. The connection adjustment mechanism includes a connection sleeve that is slidably disposed on the edge of the connection frame, and a positioning shaft that is rotatably disposed inside the connection sleeve. A positioning block that is slidably disposed inside the connection frame is installed on one side of the outer wall of the positioning shaft. A fixing block is slidably disposed inside the positioning block. A threaded lifting rod is threadedly connected to the top of the positioning shaft. A converter shaft is installed at the bottom of the threaded lifting rod. A sliding column is rotatably disposed on the outer wall of the converter shaft. The sliding column and the fixing block are connected by a pull rope.

[0007] Optionally, a limiting plate is installed on one side of the outer wall of the fixing block, and the limiting plate is slidably disposed inside the positioning block, while the other side of the outer wall of the fixing block is slidably disposed inside the connecting frame.

[0008] Optionally, a spring sheet is installed on one side of the outer wall of the limiting plate, and one side of the outer wall of the spring sheet is in contact with the inner wall of the positioning block.

[0009] Optionally, the pull rope and the sliding column are slidably disposed inside the positioning shaft and the connecting shaft sleeve, respectively.

[0010] Optionally, a handle is mounted on the top of the threaded lifting rod.

[0011] Optionally, the protective device may also include positioning and mounting mechanisms disposed on the upper and lower surfaces of the PC endurance board; The positioning and installation mechanism includes a limiting base plate installed at the bottom of the connecting frame and a positioning top plate installed at the top of the connecting frame. The bottom of the limiting base plate is equipped with a positioning block, and the positioning top plate has a limiting slot inside.

[0012] Optionally, the positioning block is slidably disposed inside the limiting slot, and both the positioning block and the positioning top plate have mounting holes.

[0013] Optionally, a fixing pin is provided inside the mounting hole, and the fixing pin passes through the positioning top plate and the positioning block.

[0014] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention achieves modular splicing of the protective structure by using PC endurance board in conjunction with the connecting adjustment mechanism and the positioning installation mechanism. This eliminates the need for complex wood board cutting and timber support operations on site, significantly reducing the labor and time costs of transportation, unloading, and installation.

[0015] Furthermore, the connection adjustment mechanism enables rapid locking and unlocking. Meanwhile, the upper and lower layers are locked by the insertion and cooperation of positioning blocks and limit slots and the locking pins, so that the entire protective device can be completely disassembled and reused multiple times after the project is completed, which significantly improves the material reuse rate.

[0016] The PC endurance board used in the endeavor has high transparency, which makes it easy for construction personnel to observe the operating status of the tower crane foundation at any time. At the same time, it has B1-level flame retardant properties and impact resistance far exceeding that of ordinary glass. In the event of accidental impact or fire hazard, it can effectively ensure the integrity of the protective structure and improve the overall safety level of the construction site.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other. Example

[0020] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the present invention proposes a horizontal protection device for a socket tower crane, comprising multiple PC endurance boards 1, multiple connecting frames 7, and a connection adjustment mechanism disposed between the multiple connecting frames 7; the connection adjustment mechanism includes a connecting bushing 9 slidably disposed on the edge of the connecting frame 7, and a positioning shaft 8 rotatably disposed inside the connecting bushing 9, a positioning block 10 slidably disposed inside the connecting frame 7 installed on one side of the outer wall of the positioning shaft 8, a fixing block 11 slidably disposed inside the positioning block 10, and a threaded lifting rod 17 threadedly connected to the top of the positioning shaft 8, a transition shaft 16 installed at the bottom of the threaded lifting rod 17, a sliding column 15 rotatably disposed on the outer wall of the transition shaft 16, and the sliding column 15 and the fixing block 11 are connected by a pull rope 14; Multiple connecting frames 7 are respectively installed on the outer walls of multiple PC endurance boards 1; a limiting plate 12 is installed on one side of the outer wall of the fixing block 11, and the limiting plate 12 is slidably disposed inside the positioning block 10, and the other side of the outer wall of the fixing block 11 is slidably disposed inside the connecting frame 7; a spring plate 13 is installed on one side of the outer wall of the limiting plate 12, and one side of the outer wall of the spring plate 13 is in contact with the inner wall of the positioning block 10; the pull rope 14 and the sliding column 15 are respectively slidably disposed inside the positioning shaft 8 and the connecting bushing 9; a handle 18 is installed on the top of the threaded lifting rod 17. The following is a detailed description of the connecting adjustment mechanism: In this embodiment, when construction workers need to build horizontal protection around the tower crane foundation, they first preliminarily enclose multiple PC endurance boards 1 using connecting frame 7 installed on their outer walls. Each connecting frame 7 has a connecting bushing 9 slidably mounted on its edge, and a positioning shaft 8 is rotatably mounted inside the connecting bushing 9. In the initial unlocked state, the positioning block 10 is slidably mounted inside the connecting frame 7, while the fixing block 11 is held in a retracted position inside the positioning block 10 by the limiting plate 12 under the elastic force of the spring plate 13. At this time, the end of the fixing block 11 has not yet extended into the slot of the connecting frame 7, thus allowing the connecting frames 7 of two adjacent PC endurance boards 1 to freely slide relative to each other and adjust their positions, so that construction workers can splice the PC endurance boards 1 into the required closed shape according to the size and shape of the tower crane standard section.

[0021] After the positions of the two adjacent PC endurance boards 1 are adjusted into place, the construction personnel operate the handle 18 to rotate the threaded lifting rod 17. Since the threaded lifting rod 17 is threadedly connected to the top of the positioning shaft 8, it will move axially relative to the positioning shaft 8 as it rotates. The axial movement of the threaded lifting rod 17 drives the adapter shaft 16 at its bottom to move synchronously, and the adapter shaft 16 in turn drives the sliding column 15, which is rotatably connected to it, to slide axially inside the positioning shaft 8 and the connecting bushing 9. The sliding of the sliding column 15 will tension or release the pull rope 14 connected to the fixed block 11. When the threaded lifting rod 17 moves closer to the fixed block 11, the pull rope 14 loosens, and the fixed block 11, under the return force of the spring plate 13, slides outward from the retracted position through the guide of the limiting plate 12, and finally inserts into the preset slot of the adjacent connecting frame 7, thereby realizing the mechanical interlock between the two connecting frames 7. During this process, since the positioning shaft 8 can rotate within the connecting sleeve 9, and the positioning block 10 is also slidably positioned inside the connecting frame 7, the locking action can adapt to splicing requirements at different angles and positions. Conversely, if disassembly or position adjustment is required, the threaded lifting rod 17 is rotated in the opposite direction, causing the pull rope 14 to tighten and overcome the elastic force of the spring plate 13, pulling the fixing block 11 back to the retracted state and releasing the lock. This achieves a fast, reliable, and reversible splicing connection between multiple PC endurance boards 1. Example

[0022] like Figures 1-3 As shown, based on Embodiment 1, the tower crane horizontal protection device also includes a positioning and installation mechanism set on the upper and lower surfaces of the PC endurance board 1; the positioning and installation mechanism includes a limiting base plate 2 installed at the bottom of the connecting frame 7 and a positioning top plate 3 installed at the top of the connecting frame 7, a positioning block 4 is installed at the bottom of the limiting base plate 2, and a limiting slot 5 is opened inside the positioning top plate 3. The positioning block 4 is slidably disposed inside the limiting slot 5, and both the positioning block 4 and the positioning top plate 3 have mounting holes; a fixing pin 6 is provided inside the mounting hole, and the fixing pin 6 passes through the positioning top plate 3 and the positioning block 4. The positioning installation mechanism is described in detail below: In this embodiment, when it is necessary to increase the protective height or connect the upper and lower layers of the spliced ​​PC endurance board 1, the construction personnel will use the positioning and installation mechanism set on the upper and lower surfaces of the PC endurance board 1. A limiting base plate 2 is fixedly installed at the bottom of each connecting frame 7, and a positioning block 4 is further installed on the lower surface of the limiting base plate 2; at the same time, a positioning top plate 3 is fixedly installed at the top of each connecting frame 7, and a limiting slot 5 is opened inside the positioning top plate 3.

[0023] When the upper and lower protective units need to be stacked vertically, the construction personnel place the bottom limiting plate 2 of the upper unit on top of the positioning plate 3 of the lower unit. At this time, the positioning block 4 of the upper unit aligns and begins to be inserted into the limiting slot 5 of the lower unit. Since the size of the limiting slot 5 is slightly larger than the positioning block 4, the positioning block 4 can slide horizontally within a small range inside the limiting slot 5 during insertion. This allows the construction personnel to fine-tune the position of the upper unit before final locking, ensuring that it is completely aligned with the lower unit and guaranteeing the integrity and verticality of the entire protective structure. After the positions of the upper and lower units are adjusted, the mounting holes on the positioning block 4 and the positioning plate 3 will align with each other. At this time, the construction personnel only need to insert the fixing pin 6 through the mounting holes on both the positioning plate 3 and the positioning block 4 to securely lock them together and prevent relative displacement. This allows the PC endurance board 1 to be modularly stacked and fixed in the vertical direction, which not only improves the adjustability of the protective height but also makes the installation of the entire protective structure more stable and convenient.

[0024] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
