DETAILED DESCRIPTION
[0025] In order to make the purpose and the advantage of the utility model more clearly, the following is combined with embodiment to the utility model specific description.It should be understood, the following text only to describe the utility model one or several specific implementation ways, and does not strictly limit the protection scope of the utility model specific request.
[0026] As Figures 1-5 Shown, a kind of construction engineering safety protection net, including two symmetrical fixed pile 1 and intercept net 2, the fixed pile 1 is provided with elastic fixing assembly 5, the one side of intercept net 2 is arranged on elastic fixing assembly 5, the bottom surface of fixed pile 1 is fixedly installed with bottom plate 3, the side surface of bottom plate 3 and fixed pile 1 is welded with reinforcing plate 4;
[0027] The upper side of the fixed pile 1 is covered with an upper cover ring 7a, and a fixed ring is fixedly installed on the inner top surface of the upper cover ring 7a, which is used to stabilize the elastic fixing assembly 5. The elastic fixing assembly 5 comprises a stabilizing shaft 51, two torsion springs 52 and a plug-in rod 54. The stabilizing shaft 51 is arranged inside the fixed pile 1. A lower cover ring 1b and a lower block 1c are fixedly installed on the inner bottom surface of the fixed pile 1. The lower side of the stabilizing shaft 51 is in plug-in cooperation with the lower cover ring 1b. The upper side of the stabilizing shaft 51 is in plug-in cooperation with the upper cover ring 7a. Two rotating plates 53 are fixedly installed on the stabilizing shaft 51. The plug-in rod 54 is sleeved in the hole formed on the two rotating plates 53. A fixed nut 54a is arranged on the upper side of the rotating plate 53. The upper side of the stabilizing shaft 51 is in threaded cooperation with the fixed nut 54a through the arranged thread. One side of the intercepting net 2 passes around the stabilizing shaft 51 and is fixedly installed on the plug-in rod 54 between the two rotating plates 53.
[0028] The two torsion springs 52 are respectively sleeved on the upper and lower sides of the stabilizing shaft 51. The torsion springs 52 are located on the opposite sides of the two rotating plates 53. One side of the torsion spring 52 is clamped on the side surface of the rotating plate 53. The upper side of the fixed pile 1 is fixedly installed with an upper block 8. The other side of the upper torsion spring 52 is clamped on the side surface of the upper block 8. The other side of the lower torsion spring 52 is clamped on the side surface of the lower block 1c.
[0029] As an optional implementation, a blunt hole is formed on the side surface of the fixed pile 1, which is used to install the intercepting net 2 into the fixed pile 1. The other side of the fixed pile 1 is provided with an opening and a movable back plate 6. The opening side of the other side of the fixed pile 1 is provided with a sliding groove 1a. The movable back plate 6 is in sliding cooperation with the sliding groove 1a. This arrangement can make the cap 7 separate from the fixed pile 1, and then the movable back plate 6 is taken out of the sliding groove 1a, so as to facilitate the installation of the elastic fixing assembly 5, and also facilitate the subsequent replacement of the intercepting net 2, thereby improving the actual application effect.
[0030] Referring to the accompanying drawings Figure 3 and the accompanying drawings Figure 5 , the upper cover ring 7a and the lower cover ring 1b are located near the hole in the fixed pile 1. The upper cover ring 7a and the lower cover ring 1b are arranged at two-thirds of the distance between the two sides of the fixed pile 1. This arrangement can make the intercepting net 2 pass through the hole and connect the stabilizing shaft 51 and the plug-in rod 54, so as to provide rotating support and space for the rotating plate 53 on the stabilizing shaft 51 by using the positions of the upper cover ring 7a and the lower cover ring 1b.
[0031] Further, the length of the rotating plate 53 is set to be three-fourths of the distance between the lower cover ring 1b and the farther side inside the fixed pile 1. This arrangement can make the rotating plate 53 have enough rotating space in the fixed pile 1, so as to facilitate the rotating adjustment of the rotating plate 53 with the stabilizing shaft 51 as the center.
[0032] Further, the distance between the movable back plate 6 and the lower cover ring 1b is set to be 1.2 times the length of the rotating plate 53, so that the rotating range of the rotating plate 53 is increased when the rotating plate 53 rotates under the driving of the intercepting net 2, so as to sufficiently twist the torsion spring 52, and the instantaneous pulling of the intercepting net 2 is buffered by the elastic torsion of the torsion spring 52.
[0033] With the above structure, when the intercepting net 2 is pulled or impacted, the intercepting net 2 drives the inserting rod 54 to move, drives the rotating plate 53 and the stable shaft 51 to rotate, and the rotating plate 53 rotates to pull the torsion spring 52, so that the rotating plate 53 is slowed down by the elastic torsion of the torsion spring 52, thereby slowing down the instantaneous pulling force of the intercepting net 2. When the intercepting net 2 is continuously pulled, the rotating plate 53 is driven to rotate against the inner side of the fixed pile 1, so that the rotating plate 53 is in a braking state, thereby slowing down and supporting the intercepting net 2, maintaining the protection effect of the intercepting net 2. In this way, when the intercepting net 2 is pulled or impacted, the instantaneous impact of the intercepting net 2 on the fixed pile 1 is reduced by the elastic fixing assembly 5, thereby improving the protection of the fixed pile 1 and prolonging the service life of the fixed pile 1.
[0034] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
