[0025] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0026] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0027] like Figure 1 The tool-type self-lifting construction site gate shown includes a door crossbeam 300 and door posts 100 supporting both ends of the door crossbeam 300, and the door crossbeam 300 and the door posts 100 are respectively connected by multiple sections of standard sections. The mating surfaces between the standard sections are provided with bolt holes and are fixed by bolt connection. The lower end of the door post 100 is connected to the cast-in-place concrete foundation 1, and the cast-in-place concrete foundation 1 is pre-set with anchor bolts 2 for installing the door post 100. The door crossbeam 300 is inserted into the door post 100, so that the door crossbeam 300 is guided by the door post 100 to move the door crossbeam 300 along the length direction of the door post 100, thereby adjusting the height of the door crossbeam 300. The connection between the door crossbeam 300 and the door post 100 is achieved in this way, refer to Figure 2 The standard section for connecting the door cross beam 300 and the door post 100 is the door cross beam end standard section 400; the door cross beam end standard section 400 is provided with an installation opening 401 on the upper and lower sides. When pre-installing the construction site gate, firstly, the lower end of the door post 100 is threadedly connected to the cast-in-place concrete foundation 1, and then the installation opening 401 of the door cross beam end standard section 400 is installed, and two door cross beam end standard sections 400 are connected to form a complete door cross beam 300 by using multiple door cross beam standard sections, and the door cross beam 300 is lifted by a lifting device, and fixed after it is raised to the position. The installation opening 401 of the door cross beam end standard section 400 is provided with installation holes on the opposite sides, and corresponding round steel 19 is arranged in the installation holes. The round steel 19 passes through the two installation holes arranged oppositely on the installation opening along the length direction of the door cross beam end standard section 400, and is used to fix the door cross beam 300 and the door post 100, and the round steel 19 is in the same direction as the door cross beam 300. The material used for the door post 100 and the door cross beam 300 is angle steel.

[0028] Reference Figure 3The standard section connecting the door post 100 and the door cross beam 300 is the door post top standard section 200. The upper part of the door post top standard section 200 of the two door posts is provided with an electric hoist 12, and the electric hoist 12 is fixedly connected to the upper part of the door post top standard section 200 through two channel steels 11, and the electric hoist 12 is arranged on the opposite side of the two door posts 100. The size of the installation opening 401 is larger than the combined size of the door post top standard section 200 and the electric hoist 12, so that the door cross beam 300 can move along the length direction of the door post 100 through its installation opening 401. In order to strengthen the connection between the door post 100 and the door cross beam 300, a connection hole 131 corresponding to the installation hole position of the installation opening 401 of the door cross beam end standard section 400 is arranged at the upper end of the door post top standard section 200. After the door cross beam 300 is lifted into place along the door post 100 by the electric hoist 12, the round steel 19 is passed through the mounting hole and the connecting hole 131 to fix the position of the door cross beam 300 and the door post 100. Lifting rings are set on both sides of the width direction of the standard section 400 at the end of the door cross beam, and the two ends of the lifting rope 600 are connected to the two lifting rings 24, and then the lifting rope 600 is hooked with the hook of the electric hoist 12. When lifting the door cross beam 300, the electric hoist 12 can quickly slide to the middle of the lifting rope 600. During the lifting process, the door cross beam 300 swings left and right, and it is easy to collide with the bolt head on the door post 100, which makes lifting inconvenient.

[0029] To solve this problem, the current choice is to increase the size of the installation opening 401, but this will increase the manufacturing cost of the door beam 300. To this end, an anti-collision guide device is designed, referring to Figure 4The anti-collision guide device includes an angle plate 3, a spring 4, and a clip mechanism. The angle plate 3 is welded into an angle by two flat plates, and its angle is 120-160°. The joint of the two flat plates is a circular arc transition surface. The clip mechanism is an η-shaped structure, which includes a fixed plate 5, a movable plate 51, and a locking bolt 6. The upper end of the fixed plate 5 is a hook 52. The upper end of the movable plate 51 is plugged into the end of the hook 52 of the fixed plate 5, and the upper part of the movable plate 51 and the fixed plate 5 are provided with positioning holes 510 corresponding to each other. The locking bolt 6 is inserted into the two positioning holes 510 and screwed with nuts to fix. There are two springs 4, one end of the two springs 4 is respectively fixed to the lower end of the fixed plate 5 and the lower end of the movable plate 51; the other ends of the two springs 4 are respectively fixed to the two flat plates of the angle plate 3. In this way, when in use, first separate the movable plate 51 and the fixed plate 5, and then hang the entire anti-collision guide device on the angle steel 23 (cross bar of the standard section at the end of the door beam) at the bottom of the standard section 400 at the end of the door beam, and clamp the vertical surface of the angle steel 23 between the fixed plate 5 and the movable plate 51, and the horizontal surface of the angle steel 23 is located between the two springs 4; insert the movable plate 51 into the hook 52 end of the fixed plate 5, tighten the nut on the locking bolt 6, and the anti-collision guide device can be clamped on the angle steel 23; at this time, the arc transition surface of the angle plate 3 points to the door post 100. An anti-collision guide device is provided on each side of the door post 100, and the door post 100 is located between the two anti-collision guide devices; in the process of lifting the door cross beam 300, when the door post 100 collides with the door cross beam 300, the angle plate 3 first hits the door post 100, and can pass smoothly by utilizing the elastic deformation of the spring 4 and the arc transition surface of the angle plate 3, without causing the door cross beam 300 to stop instantly. By providing an anti-collision guide device, the size of the door cross beam 300 can be further reduced, saving steel. In a preferred embodiment, a horizontal connecting shaft 7 is provided at the end of the hook portion 52 of the fixed plate 5, and a radial limiting surface is provided at the end of the connecting shaft; the upper end of the movable plate 51 is a hook portion, and is hooked on the connecting shaft 7, thereby strengthening the connection between the movable plate 51 and the fixed plate 5.
