Description

Technical Field

[0001] This application relates to the technical field of crane beam systems, and in particular to a cantilever crane beam support structure. Background Technology

[0002] Currently, industrial plants generally use steel structure crane beam systems to bear the load of lifting equipment. Traditional support methods mostly use direct column support or cantilevered corbel structures. However, with the increase in plant span (over 30 meters) and crane tonnage (over 50 tons), the situation is changing.

[0003] The crane beam in the relevant technical center is supported on the columns by abutment blocks. The beam adopts a segmented design, and the length of the beam at one end is the distance between the two columns. It is now required that the outermost column be removed to ensure that there is a certain space for movement under the outermost end of the beam. However, after removing the outermost column, there is no support under the outermost end of the beam, which leads to a low safety factor and poor structural stability of the beam. Therefore, it is necessary to propose a cantilever crane beam support structure to solve the above problems. Utility Model Content

[0004] To address the problem that existing technologies leave the beam's outermost end unsupported after the outermost column is removed, resulting in a low safety factor and poor structural stability, this application provides a cantilever crane beam support structure.

[0005] This application provides a cantilever crane beam support structure, which adopts the following technical solution: A cantilever crane beam support structure includes a crane beam, a first column fixedly installed at the bottom of the crane beam, the right end of the crane beam extending to the right side of the first column, a second column fixedly connected to the bottom of the crane beam on the left side of the first column, and several connecting rods, which are angle irons, fixedly installed on the inner side of the crane beam; a reinforcing component is provided on the top of the crane beam for reinforcing the crane beam.

[0006] By adopting the above technical solution, the right end of the crane beam is extended to the right side of the first column. The outermost crane beam is no longer designed in segments, but in one piece. This allows part of the crane beam to be suspended in the air. Furthermore, by setting several connecting rods that form a triangular shape, triangular stability is achieved. Several cross connecting rods are used to connect and reinforce the crane beam, thereby improving the safety factor and structural stability of the crane beam.

[0007] A further improvement of the technical solution of this application is that: the reinforcing component includes a pair of reinforcing side plates, which are respectively arranged on the front and rear sides of the crane beam. Several T-shaped blocks are fixedly installed on both the front and rear sides of the crane beam, and the T-shaped blocks are interlocked with the interior of the reinforcing side plates.

[0008] By adopting the above technical solution, the reinforcement components work together to provide targeted reinforcement to the stress concentration points on the front and rear sides of the crane beam at the top of the first column by setting up reinforcement side plates. The T-blocks allow for easy installation and removal of the reinforcement side plates on the front and rear sides of the crane beam. The detachable design of the reinforcement side plates allows for individual inspection, repair, or replacement without affecting the main beam structure, resulting in extremely low maintenance costs. Furthermore, reinforcement side plates of different thicknesses or higher strengths can be easily replaced according to future crane upgrades or load changes, giving the structure good scalability.

[0009] A further improvement of the technical solution of this application is that: the front and rear outer surfaces of the reinforced side plate are provided with inclined surfaces that slope towards the right front and rear inner sides.

[0010] By adopting the above technical solution, the maximum support is provided at the root where the material is most needed, and the material is reduced at the end where less material is needed, thus maximizing structural efficiency and minimizing weight. Furthermore, by setting the continuously changing slope, the force flow can be smoothly and continuously transmitted, avoiding abrupt changes in the cross-section, thereby improving the fatigue resistance of the structure and extending the service life of the reinforced side plate.

[0011] A further improvement of the technical solution of this application is that: connecting plates are symmetrically installed at the bottom of the crane beams on the left and right sides of the first column; fixing plates are fixedly connected to the left and right sides of the first column; a supporting inclined plate is inserted between the connecting plate and the fixing plate; a first guide plate is fixedly installed on the top of the supporting inclined plate; the first guide plate is fitted into the interior of the connecting plate; and a second guide plate is fixedly installed on the left and right inner sides of the supporting inclined plate; the second guide plate is fitted into the interior of the fixing plate.

[0012] By adopting the above technical solution, in this solution, by inserting the first guide plate into the interior of the connecting plate and the second guide plate into the interior of the fixing plate, the supporting inclined plate can be set between the first column and the crane beam, thereby supporting and reinforcing the extended end of the crane beam, and thus further improving the structural strength of the crane beam.

[0013] A further improvement of the technical solution of this application is that: a reinforcing frame is fixedly installed on the left and right sides of the first column at the top of the fixed plate, and the top of the reinforcing frame is fixedly connected to the crane beam; a third guide plate is fixedly installed on the left and right inner sides of the supporting inclined plate at the top of the second guide plate, and the third guide plate is fitted into the interior of the reinforcing frame.

[0014] By adopting the above technical solution, the supporting inclined plate can be connected to the supporting inclined plate through the cooperation between the reinforcing frame and the third guide plate, thereby improving the structural strength of the supporting inclined plate and further improving the structural strength of the crane beam.

[0015] A further improvement to the technical solution of this application is that a baffle is rotatably installed on the front side of the reinforcing frame, and the baffle is located on the front side of the third guide plate.

[0016] In the above technical solution, the third guide plate can be limited from the front by installing a baffle, thereby preventing the support inclined plate from moving forward and ensuring normal use of the support inclined plate.

[0017] A further improvement of the technical solution of this application is that: the front side of the connecting plate has an opening larger than the size of the rear cross section of the first guide plate, the front side of the fixing plate has an opening larger than the size of the rear cross section of the second guide plate, and the front side of the reinforcing frame has an opening larger than the size of the rear cross section of the third guide plate.

[0018] By adopting the above technical solution, by providing openings on the front side of the connecting plate, fixing plate, and reinforcing frame, the first guide plate, second guide plate, and third guide plate can be easily inserted into the interior of the connecting plate, fixing plate, and reinforcing frame, thereby facilitating the installation of the support inclined plate and improving installation efficiency.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a cantilever crane beam support structure. By extending the right end of the crane beam to the right side of the first column, the outermost crane beam is no longer designed in segments but in one piece, so that part of the crane beam is suspended in the air. Furthermore, by setting several cross connecting rods, the crane beam can be connected and reinforced, thereby improving the safety factor and structural stability of the crane beam.

[0020] 2. This application provides a cantilever crane beam support structure. By setting reinforcement components, the "critical parts" where stress is concentrated on the front and rear sides of the crane beam at the top of the first column can be specifically reinforced. Furthermore, by designing the reinforcement side plates to be detachable, the reinforcement side plates can be inspected, repaired, or replaced individually without affecting the main beam structure, resulting in extremely low maintenance costs. At the same time, reinforcement side plates of different thicknesses or higher strengths can be easily replaced according to the needs of future crane upgrades or load changes, giving the structure good scalability.

[0021] 3. This application provides a cantilever crane beam support structure. By setting up support inclined plates and other structures, the extended ends of the crane beam can be supported and reinforced, thereby further improving the structural strength of the crane beam. Furthermore, by designing the support inclined plates to be detachable, the support inclined plates can be inspected, repaired, or replaced individually without affecting the main beam structure, resulting in extremely low maintenance costs. At the same time, according to the needs of future crane upgrades or load changes, support inclined plates of different thicknesses or higher strengths can be easily replaced, giving the structure good scalability.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] Example 1 See Figure 1 and Figure 2 This application provides a cantilever crane beam support structure, including a crane beam 1, a first column 2 fixedly installed at the bottom of the crane beam 1, the right end of the crane beam 1 extending to the right side of the first column 2, a second column 3 fixedly connected to the bottom of the crane beam 1 on the left side of the first column 2, and a plurality of connecting rods 4 fixedly installed on the inner side of the crane beam 1, the plurality of connecting rods 4 being angle irons; a reinforcing component is provided on the upper part of the crane beam 1, the reinforcing component being used to reinforce the crane beam 1.

[0026] In this embodiment, by extending the right end of the crane beam 1 to the right side of the first column 2, the outermost crane beam 1 is no longer designed in segments, but in one piece, so that part of the crane beam 1 is suspended in the air. Furthermore, by setting several connecting rods 4 that form a triangular shape, triangular stability is formed, and several cross connecting rods 4 connect and reinforce the crane beam 1, thereby improving the safety factor and structural stability of the crane beam 1.

[0027] Example 2 See Figure 1 and Figure 2 Based on Embodiment 1, this application provides a technical solution: preferably, the reinforcing component includes a pair of reinforcing side plates 5, the reinforcing side plates 5 are respectively disposed on the front and rear sides of the crane beam 1, and a plurality of T-shaped blocks 7 are fixedly installed on both the front and rear sides of the crane beam 1, the T-shaped blocks 7 are engaged with the interior of the reinforcing side plates 5; the front and rear outer surfaces of the reinforcing side plates 5 are provided with inclined surfaces that are inclined to the right and the front and rear inner sides.

[0028] In this embodiment, through the cooperation between the reinforcing components, the reinforcing side plate 5 can be used to specifically reinforce the "critical parts" where stress is concentrated on the front and rear sides of the crane beam 1 at the top of the first column 2. The T-block 7 allows for easy installation and removal of the reinforcing side plate 5 on the front and rear sides of the crane beam 1. The detachable design of the reinforcing side plate 5 allows for individual inspection, repair, or replacement without affecting the main beam structure, resulting in extremely low maintenance costs. Furthermore, the reinforcing side plate 5 can be easily replaced with one of different thicknesses or higher strengths to meet future crane upgrades or load changes, giving the structure good scalability. By setting the surface of the reinforcing side plate 5 at an angle, maximum support is provided at the root where material is most needed, while less material is needed at the end, maximizing structural efficiency and minimizing weight. The continuously changing slope ensures smooth and continuous force transmission, avoiding abrupt changes in cross-section, thereby improving the fatigue resistance of the structure and extending the service life of the reinforcing side plate 5.

[0029] Example 3 See Figure 1 , Figure 3 and Figure 4 Based on Embodiment 2, this application provides a technical solution: Preferably, connecting plates 8 are symmetrically installed at the bottom of the crane beams 1 on both sides of the first column 2; fixing plates 9 are fixedly connected to both sides of the first column 2; a supporting inclined plate 6 is inserted between the connecting plate 8 and the fixing plate 9; a first guide plate 12 is fixedly installed on the top of the supporting inclined plate 6, and the first guide plate 12 is fitted into the interior of the connecting plate 8; a second guide plate 13 is fixedly installed on the left and right inner sides of the supporting inclined plate 6, and the second guide plate 13 is fitted into the interior of the fixing plate 9; and reinforcing plates are fixedly installed on both sides of the first column 2 at the top of the fixing plate 9. The top of the frame 10 is fixedly connected to the crane beam 1. The third guide plate 14 is fixedly installed on the left and right inner sides of the supporting inclined plate 6 on the top of the second guide plate 13. The third guide plate 14 fits into the interior of the reinforcement frame 10. A baffle 11 is rotatably installed on the front side of the reinforcement frame 10. The baffle 11 is located in front of the third guide plate 14. The front side of the connecting plate 8 has an opening larger than the size of the rear cross section of the first guide plate 12. The front side of the fixing plate 9 has an opening larger than the size of the rear cross section of the second guide plate 13. The front side of the reinforcement frame 10 has an opening larger than the size of the rear cross section of the third guide plate 14.

[0030] In this embodiment, by inserting the first guide plate 12 into the interior of the connecting plate 8 and the second guide plate 13 into the interior of the fixing plate 9, the supporting inclined plate 6 can be placed between the first column 2 and the crane beam 1, thereby supporting and reinforcing the extended end of the crane beam 1, and further improving the structural strength of the crane beam 1. Through the cooperation between the reinforcing frame 10 and the third guide plate 14, the supporting inclined plate 6 can be connected to the reinforcing frame 10, thereby improving the structural strength of the supporting inclined plate 6, and further improving the structural strength of the crane beam 1. By installing the baffle 11, the third guide plate 14 can be limited from the front, thereby preventing the supporting inclined plate 6 from moving forward and ensuring normal use of the supporting inclined plate 6. By providing openings on the front of the connecting plate 8, the fixing plate 9, and the reinforcing frame 10, the first guide plate 12, the second guide plate 13, and the third guide plate 14 can be easily inserted into the interior of the connecting plate 8, the fixing plate 9, and the reinforcing frame 10, respectively, thereby facilitating the installation of the supporting inclined plate 6 and improving installation efficiency.

[0031] The working principle of this cantilever crane beam support structure is explained in detail below.

[0032] like Figures 1-4 As shown, the operator inserts the reinforcing side plate 5 into the outer surface of the T-shaped block 7 to improve the structural strength of the front and rear sides of the crane beam 1. Then, the baffle 11 is rotated upward to insert the first guide plate 12, the second guide plate 13 and the third guide plate 14 into the interior of the connecting plate 8, the fixing plate 9 and the reinforcing frame 10, respectively. This allows the supporting inclined plate 6 to be installed between the first column 2 and the crane beam 1, supporting the bottom of the crane beam 1 and thus improving the structural strength of the crane beam 1.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
