Abstract
Description
Technical Field
[0001] This utility model relates to the field of space frame construction technology, specifically a mobile safety net device for high-altitude bulk construction of space frames. Background Technology
[0002] "Space frame" generally refers to "spatial grid structure" or "spatial space frame", which is a three-dimensional structural system composed of points and rods. It is often used for the roof structure of large buildings such as industrial plants, stadiums, exhibition centers, and airport terminals.
[0003] The high-altitude construction of the space frame usually involves hoisting equipment and construction workers assembling and installing the space frame that has been hoisted to a suitable position. During this process, construction workers usually only use safety ropes for safety protection, which not only has poor protection effect, but also results in slow movement of personnel on the high space frame, leading to low construction efficiency. In addition, the risk of construction workers falling is relatively high. Utility Model Content
[0004] The purpose of this utility model is to provide a mobile safety net device for high-altitude bulk construction of space frames. By setting up a main steel cable, a sliding track, a net bag steel cable, and a safety net bag, it solves the problem that in the high-altitude construction of space frames, which is usually done by hoisting equipment and construction personnel to splice and install the space frame that has been hoisted to a suitable position, construction personnel usually only use safety ropes for safety protection. This not only has poor protection effect, but also results in slow movement of personnel on the high-altitude space frame, leading to low construction efficiency and a high risk of fall for construction personnel.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mobile safety net device for high-altitude bulk construction of space frames, comprising two main steel cables, a sliding rail sleeved on the surface of the two main steel cables, a plurality of steel cable hooks fixedly connected to one side of the sliding rails, a net steel cable inserted inside the plurality of steel cable hooks, a lifting ring sleeved on the surface of the net steel cable, and a safety net connected to the net steel cable through the lifting ring.
[0006] Preferably, the inner wall of the sliding track is provided with a mounting hole, and a pulley is rotatably connected inside the mounting hole.
[0007] Preferably, one end of the sliding track has a socket, and a bolt for fixing the extension rod is inserted into the socket.
[0008] Preferably, a threaded seat is fixedly connected to the top end of the extension rod, and a screw is threadedly connected to the inside of the threaded seat.
[0009] Preferably, an arc-shaped brake pad is rotatably connected to the bottom end of the screw, and a knob is fixedly connected to the top end of the screw.
[0010] Preferably, a traction seat is fixedly connected to one side of the extension rod.
[0011] This utility model provides a mobile safety net device for high-altitude bulk construction of space frames, which has the following beneficial effects:
[0012] In use, two high-altitude cableways are formed by connecting the two ends of the steel cable main cable to the net frame. The equipment slides on the steel cable main cable, and the safety net installed inside the steel cable net bag supports the construction personnel, which facilitates the rapid movement and construction work of personnel at high altitudes. In addition, the equipment can be flexibly arranged and moved according to the assembly work surface, ensuring the safety of the operation and reducing the risk of personnel falling.

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment proposes a mobile safety net device for high-altitude bulk construction of space frames, including two main steel cables 1. A sliding rail 2 is sleeved on the surface of the two main steel cables 1. Multiple steel cable hooks 3 are fixedly connected to one side of the sliding rail 2. A net steel cable 4 is inserted into the inside of the multiple steel cable hooks 3. A lifting ring 5 is sleeved on the surface of the net steel cable 4. A safety net 6 is connected to the net steel cable 4 through the lifting ring 5.
[0022] The width of the main steel cable 1 can be flexibly adjusted according to the bulk working surface of the grid structure, so that it can be installed with grid structures of different spacing, ensuring the sustainability of construction. The net bag steel cable 4 and the safety net bag 6 can be adjusted and replaced to adapt to the main steel cable 1 with different spacing.
[0023] The inner wall of the sliding track 2 has a mounting hole, and a pulley 7 is rotatably connected inside the mounting hole.
[0024] The pulley 7 abuts against the main steel cable 1, thus ensuring that the sliding track 2 will not fall off after the equipment is installed and arranged. At the same time, the pulley 7 makes the equipment slide more flexibly on the main steel cable 1.
[0025] One end of the sliding track 2 has an insertion hole, and a bolt 9 for fixing the extension rod 8 is inserted into the insertion hole.
[0026] The top end of the extension rod 8 is fixedly connected to a threaded seat 10, and the threaded seat 10 is internally threaded to a screw rod 11.
[0027] The bottom end of the screw 11 is rotatably connected to an arc-shaped brake pad 12, and the top end of the screw 11 is fixedly connected to a knob 13.
[0028] When the equipment is moved to a suitable position for operation, the arc-shaped brake pad 12 can be pressed against the main steel cable 1 by rotating the knob 13, thereby fixing the position of the safety net 6 and preventing the equipment from sliding due to personnel tilting to the side during operation, thus improving the stability during construction.
[0029] A traction seat 14 is fixedly connected to one side of the extension rod 8.
[0030] With the installation of the traction seat 14, a traction rope can be tied inside it. In an emergency, with the help of outside personnel, the equipment can be moved to the end of the main steel cable 1, thereby preventing personnel from being trapped in the net and unable to evacuate.
[0031] Specifically, the mobile safety net device used for high-altitude bulk construction of space frames operates as follows: When in use, the space frames at both ends are connected by the main steel cable 1 to form two high-altitude cableways. The device slides on the main steel cable 1, and the safety net 6 installed inside the net steel cable 4 supports the construction personnel, thus facilitating rapid movement and construction work at high altitudes. Furthermore, the device is flexible in its layout and can be moved according to the assembly work surface, ensuring operational safety and reducing the risk of personnel falling.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
