Abstract
Description
Technical Field
[0001] This utility model relates to the field of frame steel technology, specifically to a frame steel structure for an automobile production line. Background Technology
[0002] Steel frame structures for automobile production lines are widely used in modern manufacturing. They have advantages such as high structural strength, good rigidity, and convenient processing and installation. Commonly used steel frame structures consist of vertical steel structures and horizontal steel structures, which are fixed together by bolts or rivets.
[0003] Conveying mechanisms are commonly used on automobile production lines to transport automotive parts and complete vehicles. These mechanisms are usually installed on a frame steel structure. Consequently, the bolts or rivets at the connection points between the vertical and horizontal steel structures are subjected to significant shear forces. Bolts or rivets subjected to shear forces for a long time are prone to cracking or even breaking, affecting the stability and safety of the production line.
[0004] Therefore, a frame steel structure for automobile production lines is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a frame steel structure for automobile production lines in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A frame steel structure for an automobile production line includes an I-shaped vertical steel structure and a C-shaped horizontal steel structure. A support plate is fixedly installed on the inner wall of the I-shaped vertical steel structure. A wedge plate is fixedly installed on the bottom surface and at the end of the C-shaped horizontal steel structure by a first bolt. When the C-shaped horizontal steel structure and the I-shaped vertical steel structure are installed, their wedge plates are inserted into the I-shaped vertical steel structure and the support plate. A limit component is fixedly connected to the top of the I-shaped vertical steel structure, and a rubber pad is fixedly installed at the end of the limit component.
[0008] Furthermore, a car-mounted conveyor mechanism is fixedly installed on the top surface of the C-shaped transverse steel structure for conveying the car body structure during car production.
[0009] Furthermore, one side wall of the support plate has an inclined structure, and when the wedge plate is inserted, the wedge surface of the wedge plate is in close contact with the inclined surface of the side wall of the support plate.
[0010] Furthermore, the limiting component includes a horizontal plate inserted into the top of the I-shaped vertical steel structure, and a second bolt is threaded into the horizontal plate and the top of the I-shaped vertical steel structure to fix the horizontal plate to the top of the I-shaped vertical steel structure. A threaded rod is threaded into the horizontal plate, and a knob is fixedly installed at the top of the threaded rod. A limiting plate is rotatably installed at the bottom of the threaded rod, and a rubber pad is fixedly installed on the bottom surface of the limiting plate.
[0011] Furthermore, the ends of the C-shaped horizontal steel structure are convex, and the convex structures at the ends of the C-shaped horizontal steel structure are movably connected to the I-shaped vertical steel structure.
[0012] Furthermore, the front and rear ends of the limiting plate are fitted to the inner wall of the I-shaped vertical steel structure, and the rubber pad on the bottom surface of the limiting plate is made of elastic rubber material. When the C-shaped horizontal steel structure and the I-shaped vertical steel structure are installed, the rubber pad is fitted to the top surface of the C-shaped horizontal steel structure.
[0013] The beneficial effects of this utility model are as follows:
[0014] The wedge plate is fixed to the surface of the C-shaped horizontal steel structure by the first bolt. The wedge plate is located inside the I-shaped vertical steel structure by the interlocking installation of the C-shaped horizontal steel structure and the I-shaped vertical steel structure. The vertical interlocking of the C-shaped horizontal steel structure allows the wedge plate to make contact with the support plate inside the I-shaped vertical steel structure. Through the contact between the inclined surface of the support plate and the wedge surface of the wedge plate, when the car body is transported by the car crane conveyor, the C-shaped horizontal steel structure is subjected to gravity, and the gap between the wedge plate and the support plate gradually decreases, so that the wedge plate can make increasingly tight contact with the support plate, achieving wedge locking. This ensures a stable connection between the I-shaped vertical steel structure and the C-shaped horizontal steel structure and avoids the breakage of bolts or rivets caused by long-term shear force.

[0025] like Figures 1 to 5As shown, a frame steel structure for an automobile production line includes an I-shaped vertical steel structure 1 and a C-shaped horizontal steel structure 2. A support plate 3 is fixedly installed on the inner wall of the I-shaped vertical steel structure 1. A wedge plate 4 is fixedly installed on the bottom surface of the C-shaped horizontal steel structure 2 and at its end via a first bolt 21. When the C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are installed, the wedge plate 4 is inserted into the I-shaped vertical steel structure 1 and the support plate 3. A limit component 5 is fixedly connected to the top of the I-shaped vertical steel structure 1, and a rubber pad 6 is fixedly installed at the end of the limit component 5. More specifically, the wedge plate 4 is fixedly installed on the surface of the C-shaped horizontal steel structure 2 by means of the first bolt 21. The C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are interlocked, so that the wedge plate 4 is located inside the I-shaped vertical steel structure 1. The C-shaped horizontal steel structure 2 is vertically interlocked so that the wedge plate 4 is in interlocking contact with the support plate 3 inside the I-shaped vertical steel structure 1. The contact between the inclined surface of the support plate 3 and the wedge surface of the wedge plate 4 allows the C-shaped horizontal steel structure 4 to move when the car body is transported by the car-mounted conveyor mechanism 7. Under the influence of gravity, the gap between the wedge plate 4 and the support plate 3 of the C-shaped horizontal steel structure 2 gradually decreases, allowing the wedge plate 4 to contact the support plate 3 more and more tightly, thus achieving wedge locking and ensuring a stable connection between the I-shaped vertical steel structure 1 and the C-shaped horizontal steel structure 2. After the C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are connected, the rubber pad 6 is driven to move vertically and contact the top surface of the C-shaped horizontal steel structure 2 through the limiting component 5, thereby vertically limiting the C-shaped horizontal steel structure 2.
[0026] A car-mounted conveyor mechanism 7 is fixedly installed on the top surface of the C-shaped transverse steel structure 2 for conveying the car body structure during automobile production. More specifically, the car-mounted conveyor mechanism 7 on the C-shaped transverse steel structure 2 enables the conveying of the car body structure.
[0027] One side wall of the support plate 3 has an inclined structure. When the wedge plate 4 is inserted, the wedge surface of the wedge plate 4 fits tightly against the inclined surface of the side wall of the support plate 3. More specifically, the tight fit between the wedge surface of the wedge plate 4 and the inclined surface of the side wall of the support plate 3 increases the vertical shear resistance at the connection between the I-shaped vertical steel structure 1 and the C-shaped horizontal steel structure 2.
[0028] The limiting component 5 includes a horizontal plate 501 inserted into the top of the I-shaped vertical steel structure 1, and a second bolt 502 is threaded into the horizontal plate 501 and the top of the I-shaped vertical steel structure 1 to fix the horizontal plate 501 to the top of the I-shaped vertical steel structure 1. A threaded rod 503 is threaded into the horizontal plate 501, and a knob 504 is fixedly installed at the top of the threaded rod 503. A limiting plate 505 is rotatably installed at the bottom of the threaded rod 503, and a rubber pad 6 is fixedly installed on the bottom surface of the limiting plate 505. More specifically, after the C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are connected, the second bolt 502 is rotated by rotating the knob 504. The second bolt 502 is threaded into the horizontal plate 501, thereby causing the limiting plate 505 and the rubber pad 6 to move vertically within the I-shaped vertical steel structure 1. This allows the limiting plate 505 and the rubber pad 6 to move vertically, so that the rubber pad 6 contacts the top surface of the C-shaped horizontal steel structure 2, thus vertically limiting the C-shaped horizontal steel structure 2.
[0029] The ends of the C-shaped horizontal steel structure 2 are convex, and these convex ends are movably inserted into the I-shaped vertical steel structure 1. More specifically, by inserting the convex ends of the C-shaped horizontal steel structure 2 into the interior of the I-shaped vertical steel structure 1, the other end of the C-shaped horizontal steel structure 2 comes into contact with the end face of the I-shaped vertical steel structure 1, thereby improving its shear resistance.
[0030] The front and rear ends of the limiting plate 505 are fitted against the inner wall of the I-shaped vertical steel structure 1, and the rubber pad 6 on the bottom surface of the limiting plate 505 is made of elastic rubber material. Furthermore, when the C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are installed, the rubber pad 6 is fitted against the top surface of the C-shaped horizontal steel structure 2. More specifically, by fitting the front and rear ends of the limiting plate 505 against the inner wall of the I-shaped vertical steel structure 1, the vertical movement of the limiting plate 505 is limited.
[0031] In summary: The wedge plate 4 is fixedly installed on the surface of the C-shaped horizontal steel structure 2 by the first bolt 21. The C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are interlocked, so that the wedge plate 4 is located inside the I-shaped vertical steel structure 1. The C-shaped horizontal steel structure 2 is vertically interlocked, so that the wedge plate 4 is in contact with the support plate 3 inside the I-shaped vertical steel structure 1. The contact between the inclined surface of the support plate 3 and the wedge surface of the wedge plate 4 allows the C-shaped horizontal steel structure 4 to be in contact with the support plate 3 inside the I-shaped vertical steel structure 1 when the car-mounted conveyor 7 is transporting the car body. Under the influence of gravity, the gap between the wedge plate 4 and the support plate 3 gradually decreases, allowing the wedge plate 4 to contact the support plate 3 more and more tightly, thus achieving wedge locking and ensuring a stable connection between the I-shaped vertical steel structure 1 and the C-shaped horizontal steel structure 2. After the C-shaped horizontal steel structure 2 and the I-shaped vertical steel structure 1 are connected, the rubber pad 6 is moved vertically by the limiting component 5 to contact the top surface of the C-shaped horizontal steel structure 2, thereby vertically limiting the C-shaped horizontal steel structure 2.
