Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
As shown in fig. 1-4, the front cross beam of the step of the escalator of the present invention comprises an elongated plate body 1, wherein the plate body 1 is a metal plate, and the thickness thereof is preferably 1.5mm-3 mm. The upper end of the plate body 1 is bent towards one side to form an upper bent part 2. The upper bending part 2 is a bearing surface and is connected with the pedal assembly of the step. The lower end of the plate body 1 is bent towards one side to form a lower bent part 3. The upper bending part 2 and the lower bending part 4 are arranged at the same side. The upper bent portion 2 is bent in a direction close to the lower bent portion 2 to form a first bent portion 4. The primary bent portion 4 is bent in a direction close to the plate body to form a secondary bent portion 5. A certain distance is formed between the secondary bending part 5 and the upper bending part 2. The above-mentioned folding angle is preferably 90 degrees. After the bending molding, the lower bending part 3 and the secondary bending part 5 are parallel to each other. The plate body 1, the upper bending part 2, the lower bending part 3, the primary bending part 4 and the secondary bending part 5 are all formed through a bending process, and the whole plane unfolding form is formed through laser cutting. And a reinforcing plate 6 is arranged between the secondary bending part 5 and the lower bending part 3. The reinforcing plate 6 is a plate structure, and the thickness thereof may be slightly larger than that of the plate body 1. The reinforcing plates 6 are distributed in the middle of the plate 1 and the upper bending part 2. Reinforcing plate 6 and plate body 1 fixed connection, the upper end of reinforcing plate 6 and the lower terminal surface butt of the secondary portion of bending 5, its lower extreme and 3 butts of the portion of bending down, and then reinforcing plate 6 supports about the portion of bending 3 and the secondary portion of bending 5 down. An upper hooking part 9 is installed on one side of the upper end of the reinforcing plate 6, and a lower hooking part 8 is installed on one side of the lower end. The upper hooking part 9 is hooked with the edge of the secondary bending part 5, and the lower hooking part 8 is hooked with the lower bending part 3. By the above-described structural design, the reinforcing plate 6 is fixed between the secondary bent portion 5 and the lower bent portion 3. On the one hand, the strength of the upper bending part 3 is improved by the arrangement of the primary bending part 4 and the secondary bending part 5. On the other hand, the reinforcing plate 6 effectively supports the secondary bent portion 3, and effectively improves the support strength of the middle portion of the upper bent portion 2.
As shown in fig. 7 and 8, mounting through holes 21 are formed in the upper bent portion 2 along the longitudinal direction of the upper bent portion 2. The secondary bent portion 5 is provided with an escape through hole 51 corresponding to the mounting through hole 21. The pedal assembly is locked with the upper bending part 2 through the long screw, and the long screw can be blocked by the secondary bending part 5 after passing through the installation through hole 21, so that the long screw cannot be locked by the nut. By processing the escape through hole 51, the secondary bent portion 5 can be avoided from being blocked.
The reinforcing plate 6 is fixedly connected to the plate body 1 in a specific manner in that threaded holes 61 are distributed in the reinforcing plate 6 on the side surface close to the plate body 1. The screw holes 61 are arranged at intervals in the up-down direction. The threaded hole 61 may be formed by a nut welded to the reinforcing plate 6. The plate body 1 is provided with a through hole 11 corresponding to the threaded hole 61. A bolt 7 is inserted into the through hole 11, and the bolt 7 is screwed with the threaded hole 61. The reinforcing plate 6 is fixedly connected with the plate body 1, the upper bending part 2, the lower bending part 3, the primary bending part 4, the secondary bending part 5 and the like without adopting a welding mode, and the welding deformation of the whole structure can be effectively avoided.
As shown in fig. 9 and 10, the upper hooking portion 9 has an L-shaped structure, and includes a first vertical portion 92 and a first horizontal portion 91 that are vertically connected to each other. The first vertical portion 92 is fixed to the upper end side of the reinforcing plate 6. The first horizontal portion 91 is mounted between the upper bent portion 2 and the secondary bent portion 5, and a lower end surface of the first horizontal portion 91 abuts against the secondary bent portion 5. In order to enable the reinforcing plate 6 to synchronously support the secondary bending part 5 and the upper bending part 2 and further improve the deformation resistance of the whole structure, when the lower end surface of the first horizontal part 91 abuts against the secondary bending part 5, the upper end surface of the first horizontal part 91 also abuts against the upper bending part 2. The first vertical portion 92 and the first horizontal portion 91 are both rigid members, and are integrally formed with the reinforcing plate 6.
The lower hooking portion 8 is also L-shaped and includes a second vertical portion 82 and a second horizontal portion 81 that are vertically connected to each other, the second vertical portion 82 is fixed to the lower end side of the reinforcing plate 6, and the second horizontal portion 82 is installed below the lower bent portion 3 and abuts against the lower bent portion 3. The second vertical portion 82 and the second horizontal portion 81 are each a rigid member, and are integrally formed with the reinforcing plate 6. The reinforcing plate 6 is firmly fixed between the lower bent portion 3 and the secondary bent portion 5 by the interaction of the first horizontal portion 92 and the second horizontal portion 82.
In order to reduce the weight of the whole structure, the lengths of the upper bending part 2 and the lower bending part 3 are both smaller than the length of the plate body 1 and are positioned in the middle of the whole structure.
During installation, the reinforcing plate 6 is pushed into the space between the secondary bending part 5 and the lower bending part 3 from one side of the plate body 1 in the length direction, the upper hooking part 5 is synchronously hooked to the edge of the secondary bending part 5, and the lower hooking part 3 is synchronously hooked to the edge of the lower bending part 3. The reinforcing plate 6 is further positioned so that the screw hole 61 corresponds to one of the through holes 11 of the plate body 1, and finally, the bolt 7 is inserted into the through hole 11 from the outside and screwed into the screw hole 61, thereby fixing the reinforcing plate 6. The above operation is repeated, and a certain number of reinforcing plates 6 are fixed in sequence.
In the present embodiment, the deformation resistance of the upper bent portion 3 is improved by the arrangement of the first bent portion 4 and the second bent portion 5. In addition, a plurality of reinforcing plate 6 is installed at the middle part of anterior crossbeam, and reinforcing plate 6 effectively supports the secondary 5 and the last 2 of bending, can effectively improve the support intensity of the mid portion of anterior crossbeam, and structural strength is high, and anti deformability is strong. Reinforcing plate 6 adopts threaded connection's mode and plate body fixed connection to carry on spacingly through last hook joint portion 9 and lower hook joint portion 8, ensure that reinforcing plate 6 firmly installs on preceding crossbeam. The reinforcing plate 6 is simple and rapid to assemble, firm and reliable.
