[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1-2 As shown, the present invention provides a construction machinery safety protection device, comprising: a movable support base 1 and at least three guide members. The top of the support base 1 is provided with a rotatable roller 4. The roller 4 is provided with a protective net 3 that passes through multiple guide members in sequence, and one of the guide members is close to the roller 4. The inner side of the protective net 3 is closed to form an operating area for protection.

[0023] Combination Figure 2-3 As shown, the top of the support base 1 is provided with an integrally formed top plate 7 and a rotating shaft 11 from top to bottom. The bottom end of the rotating shaft 11 is detachably installed on the support base 1, and the roller 4 is rotatably sleeved on the rotating shaft 11.

[0024] The above-mentioned structure consists of a support base 1, at least three guide members, and a protective net 3 provided by this utility model. The support base 1 is moved to a predetermined position by universal wheels. At least three guide members are respectively set in different directions of the operating area. The figure shows four guide members. The protective net 3 is pulled outward. At this time, the roller 4 rotates, thereby releasing the protective net 3. At this time, one end of the upper protective net 3 passes through multiple guide members in sequence, forming an isolation belt around the roller 4. The isolation belt can safely isolate the operating area.

[0025] Furthermore, to facilitate length limiting of the protective net 3 on roller 4, refer to Figure 2-4 As shown, the top plate 7 is also equipped with a limiting component for rotating and limiting the roller 4. The limiting component includes a mounting base 6 and a pin 5 installed on the outer wall of one end of the mounting base 6. A mounting groove 13 is opened at the top edge of the top plate 7. The end of the mounting base 6 facing away from the pin 5 is rotatably installed in the mounting groove 13. One end of the roller 4 has multiple limiting holes 12 arranged in a circular array. The roller 4 rotates so that the multiple limiting holes 12 pass through the pin 5 in sequence, and one end of the pin 5 can be inserted into the passing limiting holes 12. When the length of the protective net 3 is sufficient, the mounting base 6 is flipped outward in the mounting groove 13, so that the pin 5 on the mounting base 6 is inserted into the lower limiting hole 12. At this time, the roller 4 can no longer rotate on the support base 1, so the protective net 3 cannot be released, thus limiting the length of the protective net 3. By reversing the above steps, the protective net 3 can be stored or unfolded.

[0026] Furthermore, to facilitate the detachable mounting of the rotating shaft 11 onto the support base 1, refer to... Figure 3 As shown, the top of the support base 1 is provided with a threaded hole 15, and the bottom end of the rotating shaft 11 is provided with a screw 10 inserted into the threaded hole 15. The rotating shaft 11 is detachably mounted on the support base 1 through the threaded hole 15 and the screw 10. After the rotating shaft 11 is removed, the roller 4 can be inspected.

[0027] In this utility model, combined with Figure 1-3 As shown, each guide in this embodiment includes a support leg 8 and two rollers 2 symmetrically rotated on top of the support leg 8, with a limiting area formed between the two rollers 2 for the passage of the protective net 3.

[0028] Combination Figure 1 and Figure 3 As shown, the top of the support base 1 is also provided with multiple fixing holes 14, and one end of each roller 2 is fixedly inserted into the corresponding fixing hole 14.

[0029] As described above, when using the guide provided by this utility model, the support leg 8 in the guide provides a support position for the two rollers 2, and the rollers 2 can rotate on the support leg 8, so that the protective net 3 can pass through the limiting area. When the guide is not in use, the guide is inverted and inserted into the corresponding fixing hole 14, so that the guide is stored on the support base 1, which is convenient for later storage and transportation.

[0030] Furthermore, to prevent the protective net 3 from detaching from the guide, refer to Figure 1-2 As shown, the end of the protective net 3 facing away from the roller 4 is also provided with a limiting rod 9, the thickness of which is greater than the thickness of the limiting area. The end of the protective net 3 is secured in the limiting area on the guide by the limiting rod 9, preventing the end of the protective net 3 from leaving the limiting area.

[0031] 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.
