[0026] An electric sliding door for use in the construction industry according to an embodiment of the present specification will be described in detail below with reference to the accompanying drawings. Figure 1 The structural schematic diagram of an electric sliding door for the construction industry according to an embodiment of the present specification is shown. The present specification provides an electric sliding door for the construction industry, comprising: a first door column 1, a second door column 2, a sliding door 3 installed between the first door column 1 and the second door column 2, a moving mechanism, and a limiting mechanism 5. The sliding door 3 is composed of a three-dimensional door frame 31 and a door panel 32, and the three-dimensional door frame 31 is arranged on the back of the door panel 32. The moving mechanism includes a plurality of moving parts 41 arranged at the bottom of the outer frame 311 and the inner frame 312, and two guide parts respectively arranged below the bottom of the outer frame 311 and the inner frame 312; the limiting mechanism 5 includes two limiting parts respectively arranged on the first door column 1 and the second door column 2, and each of the limiting parts includes two limiting rollers 51; when the moving part 41 moves along the guide part, it drives the sliding door 3 to move, and when moving, the outer frame 311 and the door panel 32 are limited between the two limiting rollers 51.

[0027] The three-dimensional door frame 31 includes the outer frame 311, the inner frame 312, and a plurality of connecting beams 313; the outer frame 311 is arranged on the back of the door panel 32, for example, the three-dimensional door frame 31 is welded on the back of the door panel 32, and the door panel 32 is made of a 2.0 mm thick steel plate. The outer frame 311 and the inner frame 312 are arranged at intervals and the two are kept parallel, and the outer frame 311 is connected to the inner frame 312 through a plurality of connecting beams 313, for example, a plurality of connecting beams 313 are welded between the outer frame 311 and the inner frame 312.

[0028] The outer frame 311 is set according to the size of the door panel 32. The inner frame 312 can be set at the same height as the outer frame 311, or at a different height. When the height of the outer frame 311 is higher than the height of the inner frame 312, the three-dimensional door frame 31 also includes a plurality of connecting oblique beams 314. One end of the connecting oblique beam 314 is connected to the upper part of the outer frame 311, and the other end is connected to the top of the inner frame 312 or the connecting cross beam 313 connected to the top of the inner frame 312. The connection method of the connecting oblique beams 314 forms a stable triangular structure. In windy weather, the triangular structure formed by the connecting oblique beams 314 supports the outer frame 311 from being damaged by external factors.

[0029] The above-mentioned several connecting cross beams 313 and several connecting diagonal beams 314 are square tubes of the same specification but different lengths, and the square tubes are 50mm*50mm square tubes. The outer frame 311 is composed of several cross beams 3111 and several long vertical beams 3112 connected vertically and equidistantly, and the inner frame 312 is composed of several cross beams 3111 and several short vertical beams 3121 connected vertically and equidistantly. The several cross beams 3111, the several long vertical beams 3112, and the several short vertical beams 3121 are all square tubes of the same specification but different lengths. The outer frame 311 is formed by welding several cross beams 3111 and several long vertical beams 3112 vertically and equidistantly, and the inner frame 312 is formed by welding several cross beams 3111 and several short vertical beams 3121 vertically and equidistantly.

[0030] The number of the cross beams 3111 and the long vertical beams 3112 required for the outer frame 311 is set according to the width and height of the door panel 32. The cross beams 3111 are arranged at equal intervals in sequence according to the width of the door panel 32, and the long vertical beams 3112 are arranged at equal intervals in sequence according to the height of the door panel 32. The number of the cross beams 3111 and the short vertical beams 3121 required for the inner frame 312 is set according to the width and height of the outer frame 311. The distance between two adjacent short vertical beams 3121 is twice the distance between two adjacent long vertical beams 3112. The number of the cross beams 3111 of the inner frame 312 may be the same as or different from the number of the cross beams 3111 of the outer frame 311. When the outer frame 311 and the inner frame 312 are connected by the connecting cross beam 313, the bottom of the outer frame 311 and the inner frame 312 must have a height for the driving device 7 to pass when the sliding door 3 moves.

[0031] When the three-dimensional door frame 31 adopts an inclined beam, the width of the outer frame 311 is the same as that of the inner frame 312, and the height of the inner frame 312 is two-thirds of that of the outer frame 311. Along the length direction of the three-dimensional door frame 31, counterweights 6 are symmetrically installed on a plurality of the connecting beams 313. Considering that the height of the outer frame 311 is higher than that of the inner frame 312, a door panel 32 is welded to the outer side of the outer frame 311, the weight of the outer frame 311 side is greater than the weight of the inner frame 312 side, and the sliding door 3 is a relatively light three-dimensional frame structure. In order to balance the outer frame 311 side and the inner frame 312 side, the counterweights 6 are provided on the connecting beams 313 close to the inner frame 312 side. The counterweights 6 are symmetrically arranged about the center line of the inner frame 312. The number of the counterweights 6 is not limited, preferably 2, and the mass of the counterweights 6 is not limited, preferably 25 kg. The plurality of moving parts 41 are symmetrically arranged at the bottom of the outer frame 311 and the inner frame 312 along the center lines of the outer frame 311 and the inner frame 312. The bottom of the plurality of moving parts 41 is also provided with two guide parts for directional movement of the moving parts 41, and the two guide parts are parallel to the crossbeam 3111 at the bottom of the outer frame 311 and the inner frame 312. During the process of opening or closing the sliding door 3, the plurality of moving parts 41 move on the two guide parts respectively arranged at the bottom of the outer frame 311 and the inner frame 312. The two guide parts can be arranged in the same length from the first door column 1 (or the second door column 2) to the second door column 2 (or the first door column 1), and the length is twice the width of the sliding door 3, or can be greater than twice the width of the sliding door 3.

[0032] The moving part 41 may be a roller. The guiding part may be a guide rail or a groove provided on the ground. Figure 2), the two guide components include a first track 421 and a second track 422. The roller fixed to the bottom of the outer frame 311 rolls along the first track 421, and the roller fixed to the bottom of the inner frame 312 rolls along the second track 422. The first track 421 and the second track 422 share the weight of the sliding door 3, making the movement of the sliding door 3 on the double tracks more stable. The number of the rollers fixed to the bottom of the outer frame 311 is twice that of the rollers fixed to the bottom of the inner frame 312, and the rollers at the bottom of the outer frame 311 are arranged adjacent to each other. Since the driving device 7 is installed on the side of the outer frame 311, the main object driven by the driving device 7 is the roller fixed at the bottom of the outer frame 311, and the roller at the bottom of the inner frame 312 serves as an auxiliary object. The main object and the auxiliary object cooperate with each other, so that the sliding door 3 moves. The roller at the bottom of the outer frame 311 undertakes the main task of moving the sliding door 3. In order to prevent the roller at the bottom of the outer frame 311 from excessive wear. Therefore, the number of the rollers at the bottom of the outer frame 311 is set to twice the number of the rollers fixed at the bottom of the inner frame 312. The number of the rollers at the bottom of the outer frame 311 is not limited, preferably 4. Correspondingly, the number of the rollers at the bottom of the inner frame 312 is not limited, preferably 2.

[0033] The outer ring of the roller has a groove 411, and the middle of the track 42 has a protrusion 423. The groove 411 of the roller meshes with the protrusion 423 in the middle of the track 42. The outer wall of the track 42 is U-shaped, and the two side walls of the track 42 limit the two sides of the roller to prevent the roller from deviating sideways. The groove 411 of the outer ring of the roller meshes with the protrusion 423 in the middle of the track 42. In the process of the movement of the sliding door 3, in order to further avoid the possibility of the sliding door 3 deviating from the track 42, a track 42 with a U-shaped outer wall is used, and the two sides of the roller are limited in the two side walls of the track 42, thereby further preventing the roller from deviating sideways when the sliding door 3 moves.

[0034] The driving device 7 for driving the sliding door 3 is installed at the lower left of the outer frame 311. A moisture-proof base 71 is installed at the bottom of the driving device 7, and the moisture-proof base 71 is fixed to the ground by expansion screws. The sliding door 3 is opened or closed by the driving device 7. The driving device is a motor. The power of the motor is not limited, preferably 3KW. The driving device 7 is remotely controlled by a wireless remote control. A rack 3113 is provided on the inner wall of the beam 3111 at the bottom of the outer frame 311, and the rack 3113 is meshed with the rotating gear 72 of the driving device 7. The length of the rack 3113 is equal to the length of the outer frame 311. Figure 3As shown, the rack 3113 meshes with the rotating gear 72 of the driving device 7. When the driving device 7 is turned on, the rack 3113 rolls and moves following the rotating gear 72 to realize the opening or closing of the sliding door 3. The two ends of the rack 3113 are respectively equipped with stoppers 3114, and the stoppers 3114 stop the sliding door 3 when it is fully opened or closed. The limiting mechanism 5 is respectively arranged on the upper side of the first door column 1 and the second door column 2 close to the sliding door 3. The two limiting components are respectively fixed by two triangular steel brackets, and the triangular steel brackets are fastened to the first door column 1 and the second door column 2 by bolts. These triangular steel brackets are made of 5# angle iron. Two limiting rollers 51 are installed at both ends of the bottom edge of the triangular steel bracket, and the distance between the two limiting rollers 51 is precisely set to be equal to the thickness of the outer frame 311 and the door panel 32. When the sliding door 3 moves, the limiting rollers 51 will rotate at a fixed point with the movement of the outer frame 311 and the door panel 32. This design can ensure the stability and smoothness of the sliding door 3 during movement, and the rotation of the limiting rollers 51 can also play a buffering role, further enhancing the comfort and safety of the sliding door 3 during use.

[0035] The sliding door 3 is opened or closed by the cooperation of a plurality of movable parts 41 at the bottom of the outer frame 311 and the inner frame 312, and two guide parts respectively arranged below the bottom of the outer frame 311 and the inner frame 312, and the limiting mechanism 5 prevents the sliding door 3 from shifting.

[0036] The following is a further explanation of its usage.

[0037] Step S1: Use a remote controller to turn on the driving device 7, and the driving device 7 drives the rotating gear 72 to roll to drive the rack 3113 to control the movement of the sliding door 3;

[0038] Step S2: When the sliding door 3 is fully opened or closed, the sliding door 3 is braked to a stop by the stoppers 3114 installed at both ends of the rack 3113, and the driving device 7 is turned off using a remote controller.
