Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a ladder-type tray that is easy to assemble. Background Art

[0002] Cable trays are divided into trough-type, tray-type, ladder-type, grid-type and other structures, which are used to support and protect cables. The ladder-type tray adopts a trapezoidal structure design, and a firm support structure is formed between the cross arms and the side beams. It has a high load-bearing capacity, can support multiple cables and keep the overall structure stable, and is widely used in construction projects.

[0003] In traditional ladder-type trays, the cross arms and the side beams are connected by welding, bolt connection or rivet structure. Among them, for the tray connected by welding, it not only takes time and effort, but also is prone to rapid spread along the cracks if cracks appear, resulting in fracture when the structure is subjected to load; when using bolt connection, the control of the tightening force needs to be considered. If the control is improper, loosening is likely to occur; when using rivet connection, in order to reinforce the stability of the connection, several rivets need to be used in cooperation. The operation steps are cumbersome, and when the rivets do not fit tightly with the metal surface, local cracking is also likely to occur at the connection.

[0004] Therefore, the existing technology needs to be further developed. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies, and provide a ladder-type tray that is easy to assemble, so as to solve the technical problems of low installation efficiency and poor load-bearing capacity in the assembly process of the ladder-type tray components in the related technology.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions: A ladder-type tray that is easy to assemble is provided, which includes two parallel and spaced side beams and cross arms arranged between the two side beams. Each side beam is provided with a connection port and a first connection part located at the connection port. The two ends of the cross arms are respectively provided with second connection parts, and the second connection parts can be inserted into and adapted to the connection ports; when the second connection parts are inserted into the connection ports, the second connection parts are bent and deformed under the action of an external force and are stuck at the connection ports, so as to be connected to the side beams; the first connection parts are bent and deformed under the action of an external force until they abut against the inner walls of the cross arms.

[0007] Further, when the second connection parts are bent and deformed in the connection ports, the second connection parts are closely attached to the outer walls of the side beams.

[0008] Further, the first connecting portion includes two side beam connecting pieces which are oppositely arranged at the connection opening; the second connecting portion includes two cross arm connecting pieces which are oppositely arranged at the end of the cross arm; each side beam connecting piece and each cross arm connecting piece alternately surround the connection opening, and the two side beam connecting pieces and the two cross arm connecting pieces are bent in opposite directions, thereby fixing the cross arm on the side beam.

[0009] Further, the cross arm includes a first cross plate, a second cross plate and a third cross plate which are connected in sequence. The first cross plate and the third cross plate are both perpendicular to the second cross plate, so that the cross arm has an opening, and the two cross arm connecting pieces are respectively arranged at the ends of the first cross plate and the third cross plate.

[0010] Further, there are multiple connection openings, and each connection opening extends along the length direction of the two side beams respectively. There are multiple cross arms, and each cross arm is arranged corresponding to each connection opening one by one.

[0011] Further, in the easily assembled ladder-type bridge frame, the second cross plates of two adjacent cross arms are alternately connected to each connection opening of the side beam. The second cross plate of one cross arm is connected to the bottom of a certain connection opening, while the second cross plate of the adjacent other cross arm is connected to the top of the corresponding connection opening, so that the two adjacent openings form an alternating layout with one facing up and the other facing down.

[0012] Further, a first abutting piece is arranged at one end of the first cross plate away from the second cross plate, and a second abutting piece is arranged at one end of the third cross plate away from the second cross plate. The first abutting piece and the second abutting piece are both parallel to the second cross plate; when the first connecting portion is bent and deformed under an external force, one of the side beam connecting pieces abuts against both the first abutting piece and the second abutting piece; the other side beam connecting piece abuts against the second cross plate.

[0013] Further, the side beam includes a side plate and a support member. The connection opening is arranged on the side plate. The support member includes a first support plate. The end of the side plate is connected to the first support plate, and the first support plate is perpendicular to the side plate. When the cross arm is connected to the side beam, the bottom of the cross arm abuts against the support member, and the support member is used to support the cross arm.

[0014] Further, the support member further includes a second support plate which is connected to one end of the first support plate away from the side plate, and the second support plate is perpendicular to the first support plate.

[0015] Further, the support member further includes a third support plate which is connected to one end of the second support plate away from the first support plate, and the third support plate is perpendicular to the second support plate. When the cross arm is connected to the side beam, the cross arm abuts against the third support plate.

[0016] Beneficial effects:

[0017] 1. For the easily assembled ladder-type bridge frame of the present utility model, the second connecting portion of the cross arm is directly inserted into the connecting port of the side beam and undergoes bending deformation under the action of an external force, so as to be tightly connected to the first connecting portion of the side beam. This design greatly simplifies the assembly process, eliminating the need for additional connecting components such as welding, bolts or rivets, and improving the installation efficiency.

[0018] 2. The connection between the cross arm and the side beam in the easily assembled ladder-type bridge frame of the present utility model realizes tight fitting through bending deformation. This connection method is not only stable but also can effectively disperse the load, improving the load-bearing capacity of the overall structure. At the same time, the design of the support component further enhances the support effect of the side beam on the cross arm, making the entire bridge frame structure more stable.

[0019] 3. For the easily assembled ladder-type bridge frame of the present utility model, the second cross plates of adjacent cross arms are alternately connected to each connecting port of the side beam, so that the support points of each cross arm are not limited to a single linear position (i.e., the bottom or top of the connecting port), but extend to the entire planar area where the connecting port is located, forming a more compact grid-like support system in the transverse direction of the entire bridge frame structure. This planar grid support system can better resist horizontal displacement and torsion. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0029] According to an embodiment of the present invention, a ladder-type bridge frame that is easy to assemble is provided. Please refer to Figures 1 to 6 , which includes two side beams 1 arranged in parallel and at intervals and a cross arm 2 arranged between the two side beams 1. Each side beam 1 is provided with a connection port 11 and a first connection part 12 located at the connection port 11. The two ends of the cross arm 2 are respectively provided with a second connection part 21, and the second connection part 21 can be inserted into and adapted to the connection port 11; when the second connection part 21 is inserted into the connection port 11, the second connection part 21 is bent and deformed under the action of an external force and is stuck at the connection port 11, thereby connecting with the side beam 1; the first connection part 12 is bent and deformed under the action of an external force until it abuts against the inner wall of the cross arm 2. After the second connection part 21 is inserted into the connection port 11, it is bent and deformed to connect with the side beam 1, forming a firm mechanical connection. At the same time, the first connection part 12 is also bent and deformed under the action of an external force and abuts against the inner wall of the cross arm 2, further enhancing the strength and stability of the connection. Since the second connection part 21 of the cross arm 2 can be directly inserted into the connection port 11 of the side beam 1 and is bent and deformed under the action of an external force to be fixed at the connection port 11, this design greatly simplifies the assembly process, without additional connecting parts such as welding, bolts or rivets and complex operation steps, and greatly improves the installation efficiency. The ladder-type bridge frame that is easy to assemble in this embodiment solves the technical problems of low installation efficiency and poor load-bearing capacity in the assembly process of the ladder-type bridge frame components in the related art.

[0030] Refer to Figure 1 , Figure 2 and Figure 3, for the easily assembled ladder-type bridge in this embodiment, when the second connecting portion 21 is bent and deformed within the connection opening 11, the second connecting portion 21 is in close contact with the outer wall of the side beam 1. The close contact connection method helps to disperse and resist the influence of external loads on the bridge structure. When the bridge bears the weight of equipment such as cables or is subjected to other external forces, the close contact connection can reduce vibration and displacement, and improve the stability of the entire structure.

[0031] Refer to Figure 2 and Figure 3 , for the easily assembled ladder-type bridge in this embodiment, the first connecting portion 12 includes two side beam connecting pieces 121, and the two side beam connecting pieces 121 are oppositely arranged on the connection opening 11; the second connecting portion 21 includes two cross arm connecting pieces 211, and the two cross arm connecting pieces 211 are oppositely arranged at the end of the cross arm 2; each side beam connecting piece 121 and each cross arm connecting piece 211 alternately surround the connection opening 11, and the two side beam connecting pieces 121 and the two cross arm connecting pieces 211 are bent in opposite directions, so as to fix the cross arm 2 on the side beam 1. Through the alternate surrounding and reverse bending of the side beam connecting pieces 121 and the cross arm connecting pieces 211, a multi-level connection structure is formed. This structure not only increases the number of connection points, but also makes the connection tighter and more stable. Even when subjected to large external forces, it can effectively resist deformation and loosening, ensuring the stable connection between the cross arm 2 and the side beam 1. Due to the use of the connecting piece design that is easy to bend and deform, the assembly process remains simple and fast. The operator only needs to insert the second connecting portion 21 of the cross arm 2 into the connection opening 11 of the side beam 1 and apply an appropriate external force to bend and deform the connecting piece to complete the assembly, without additional connecting pieces or complex operation steps. The design of the alternately surrounding and reverse bending connecting pieces makes the connection part of the bridge more neat and beautiful, not only improving the practical performance of the bridge, but also meeting the requirements of modern architecture for aesthetics.

[0032] Refer to Figure 1 and Figure 4, for the easily assembled ladder-type bridge frame of this embodiment, the cross arm 2 includes a first cross plate 22, a second cross plate 23 and a third cross plate 24. The first cross plate 22, the second cross plate 23 and the third cross plate 24 are connected in sequence. Both the first cross plate 22 and the third cross plate 24 are perpendicular to the second cross plate 23, so that the cross arm 2 has an opening 25. Two cross arm connecting pieces 211 are respectively arranged at the ends of the first cross plate 22 and the third cross plate 24. The cross arm 2 is formed by connecting the first cross plate 22, the second cross plate 23 and the third cross plate 24 in sequence, and both the first cross plate 22 and the third cross plate 24 are perpendicular to the second cross plate 23. This design makes the cross arm 2 have a U-shaped structure, so that the second cross plate 23 contacts the side beam 1 with the largest area. The cross arm connecting pieces 211 are respectively arranged at the ends of the first cross plate 22 and the third cross plate 24, and are arranged in one-to-one correspondence with the connection ports 11 on the side beam 1. This design enables the cross arm 2 to be quickly inserted and fixed on the side beam 1 without complex installation steps and additional connecting pieces, greatly improving the assembly efficiency.

[0033] Refer to Figure 1 and Figure 6 , for the easily assembled ladder-type bridge frame of this embodiment, there are multiple connection ports 11. Each connection port 11 extends along the length direction of the two side beams 1 respectively. There are multiple cross arms 2. Each cross arm 2 is arranged in one-to-one correspondence with each connection port 11. Such a design enables the cross arms 2 to be flexibly arranged at any position of the bridge frame as needed.

[0034] Refer to Figure 1 and Figure 6 , for the easily assembled ladder-type bridge frame of this embodiment, in the easily assembled ladder-type bridge frame, the second cross plates 23 of two adjacent cross arms 2 are alternately connected to each connection port 11 of the side beam 1. The second cross plate 23 of one cross arm 2 is connected to the bottom of a certain connection port 11, while the second cross plate 23 of the adjacent other cross arm 2 is connected to the top of the corresponding connection port 11, so that the two adjacent openings 25 form an alternating layout with one facing up and the other facing down. The second cross plates 23 of adjacent cross arms 2 are alternately connected to each connection port 11 of the side beam 1, so that the support points of each cross arm 2 are not limited to a straight line position (i.e., the bottom or top of the connection port), but extend to the entire plane area where the connection port 11 is located, making the entire bridge frame structure form a more compact grid-like support system in the transverse direction. This plane grid support system can better resist horizontal displacement and torsion.

[0035] Refer to Figure 4, for the easily assembled ladder-type bridge in this embodiment, a first abutting piece 26 is provided at one end of the first cross plate 22 away from the second cross plate 23, and a second abutting piece 27 is provided at one end of the third cross plate 24 away from the second cross plate 23. Both the first abutting piece 26 and the second abutting piece 27 are parallel to the second cross plate 23; when the first connecting portion 12 is bent and deformed under an external force, one of the side beam connecting pieces 121 abuts against both the first abutting piece 26 and the second abutting piece 27; the other side beam connecting piece 121 abuts against the second cross plate 23. The abutment of the side beam connecting piece 121 with the abutting piece increases the contact area of the connecting part, thereby improving the strength and stability of the connection.

[0036] Refer to Figure 5 and Figure 6 , for the easily assembled ladder-type bridge in this embodiment, the side beam 1 includes a side plate 13 and a support member 14. The connection port 11 is provided on the side plate 13. The support member 14 includes a first support plate 141. The end of the side plate 13 is connected to the first support plate 141. The first support plate 141 is perpendicular to the side plate 13. When the cross arm 2 is connected to the side beam 1, the bottom of the cross arm 2 abuts against the support member 14, and the support member 14 is used to support the cross arm 2. The provision of the connection port 11 enables the cross arm 2 to be quickly positioned and connected to the side beam 1 during installation, reducing the installation difficulty and complexity. Since the support member 14 directly supports the cross arm 2, the adjustment work required due to inaccurate position during the installation process is reduced, improving the installation efficiency.

[0037] Refer to Figure 5 and Figure 6 , for the easily assembled ladder-type bridge in this embodiment, the support member 14 further includes a second support plate 142. The second support plate 142 is connected to the end of the first support plate 141 away from the side plate 13, and the second support plate 142 is perpendicular to the first support plate 141. The addition of the second support plate 142 further enhances the stiffness of the bridge, enabling the bridge to maintain a small deformation amount when subjected to an external force, and improving the overall structural stability and load-bearing capacity.

[0038] Refer to Figure 5 and Figure 6 , for the easily assembled ladder-type bridge in this embodiment, the support member 14 further includes a third support plate 143. The third support plate 143 is connected to the end of the second support plate 142 away from the first support plate 141, and the third support plate 143 is perpendicular to the second support plate 142. When the cross arm 2 is connected to the side beam 1, the cross arm 2 abuts against the third support plate 143. The use of multiple stacked support plates further improves the stiffness of the bridge. When subjected to an external force, the bridge can maintain a small deformation amount, ensuring the stable operation of equipment such as cables.
