The net hanging device 100 according to the embodiment of the present invention will be described with reference to the drawings attached to the specification.

A net hanging device 100 according to an embodiment of the present invention, as shown in fig. 2, includes a frame 1, rollers 2a, a blade 3, and an angle adjusting device 4.

Wherein, as shown in fig. 2 and 3, rollers 2a are installed at both ends of the frame 1. Here, the net hanging device 100 includes at least two rollers 2a, and at least one roller 2a is provided at both ends of the frame 1.

The scraper 3 is connected to the frame 1 in an angle-adjustable manner, the scraper 3 has an upward pressing state and a downward pressing state, and when the scraper 3 is in the upward pressing state, an included angle formed by the scraper 3 inclining upwards relative to the wall surface 200 is positive; when the scraper 3 is in a pressing state, the inclined angle of the scraper 3 relative to the wall surface 200 is negative. That is, the direction of inclination of the squeegee 3 with respect to the wall surface 200 differs between the pressed-up state and the pressed-down state.

The angle adjusting device 4 rotates and adjusts the angle of the squeegee 3 with respect to the frame 1 to switch the squeegee 3 between the pressed-up state and the pressed-down state. That is, the angle adjusting device 4 is connected between the blade 3 and the frame 1, and the angle adjusting device 4 can rotate the blade 3 relative to the frame 1 to switch the blade 3 between the pressed-up state and the pressed-down state.

As can be seen from the above structure, in the screen hanging device 100 according to the embodiment of the present invention, the rollers 2a are installed at the two ends of the frame 1, so that the two ends of the frame 1 can both contact the wall surface 200 through the rollers 2a, thereby ensuring that the distance between each part of the frame 1 and the wall surface 200 is consistent, and ensuring that the inclination angle of each area of the scraper 3 installed on the frame 1 and the wall surface 200 is consistent.

The roller 2a rotates to drive the frame 1 to move smoothly, so that the net hanging device 100 can hang nets on wall surfaces 200 of different heights, and the practicability of the net hanging device 100 is improved. The rollers 2a can roll on the wall surface 200 to be hung with the net, the wall surface 200 simultaneously provides support for the net hanging device 100, and workers can hang the net by using the net hanging device 100 more conveniently.

The angle adjusting device 4 can drive the scraper 3 to rotate relative to the frame 1 and adjust the angle, so that the scraper 3 can be switched between an upper pressing state and a lower pressing state.

When scraper blade 3 was in the state of pushing up, scraper blade 3 had first inclination for wall 200, and first inclination can upwards for wall 200 slope, made the contained angle that forms between scraper blade 2 and the wall 200 positive, and first inclination can guarantee that the one end butt of scraper blade 3 is on wall 200, and when hanging net device 100 removed, the butt power of scraper blade 3 one end just satisfied and impressed netted thin layer in the wall 200 that has the mortar layer on the surface.

When scraper blade 3 is in the state of pushing down, scraper blade 3 has the second inclination for wall 200, and the second inclination can be downward for wall 200 slope, makes the contained angle that forms between scraper blade 3 and the wall 200 be the burden, and the other end butt of scraper blade 3 can be guaranteed to the second inclination on wall 200, and when hanging net device 100 removed, the butt power of the scraper blade 3 other end just satisfied and is impressed netted thin layer in the wall 200 that has the mortar layer on the surface. Further, the scraper 3 is switched between the upward pressing state and the downward pressing state, so that the net hanging device 100 can be in contact with the wall surface 200 when moving net hanging in different directions, and certain pressure is applied to the net-shaped thin layer, so that the net-shaped thin layer is completely pressed into the wall surface 200 with the mortar layer on the surface, the net hanging quality is improved, and the wall surface 200 after net hanging is kept flat.

Alternatively, the net hanging device 100 moves the roller 2a up and down along the wall surface 200 during the net hanging process.

Alternatively, the netting device 100 of the present application is mainly to press a net-like thin layer, which is generally a glass fiber net and has good toughness and strength, into the wall surface 200 with a mortar layer on the surface.

Optionally, the included angle formed by the scraper 3 and the wall surface 200 in the pressed state is opposite to the included angle formed by the scraper 3 and the wall surface 200 in the pressed state. The direction of inclination of the scraper 3 relative to the wall surface 200 is ensured to be opposite when the scraper is pressed up and when the scraper is pressed down.

Optionally, when the scraper 3 is in a pressed state, an included angle formed between the scraper 3 and the wall surface 200 is 5 degrees to 30 degrees. It can be understood that when the included angle formed between the scraper 3 and the wall surface 200 in the pressed state is less than 5 degrees, the contact surface between the scraper 3 and the wall surface 200 is large, so that the acting force of the scraper 3 on the wall surface 200 is not concentrated, and the whole surface of the mesh thin layer cannot be effectively pressed into the wall surface 200 with the mortar layer on the surface; when the scraper blade 3 is greater than 30 degrees with the contained angle that wall 200 formed in the state of pushing down, can lead to the area of contact between scraper blade 3 and the wall 200 not enough, make the effort that scraper blade 3 applyed to netted thin layer not enough, influence the speed of hanging net, and then lead to scraper blade 3 can not be fast, evenly impress netted thin layer in the wall 200 that the surface has the mortar layer, reduce the quality of hanging net, consequently, the inclined angle size that scraper blade 3 slope upwards formed with wall 200 is in 5 degrees-30 degrees within ranges, the area of contact of scraper blade 3 and wall 200 is moderate when can guaranteeing to press net, the effort of scraper blade 3 is moderate, improve the quality of hanging net. The angle adjustment device 4 can adjust the blade 3 to certain specific inclination angles, such as: 5 degrees, 10 degrees, 15 degrees, 20 degrees, 30 degrees, etc.

Optionally, when the scraper 3 is in the upward pressing state, an included angle formed between the scraper 3 and the wall surface 200 is 5 degrees to 30 degrees. The beneficial effect produced is consistent with the included angle formed by the scraper 3 and the wall surface 200 when the scraper 3 is in the downward pressing state being 5-30 degrees, which is not described herein.
