Description

Technical Field

[0001] This invention relates to the field of crane technology, and more specifically to a crane assembly device. Background Technology

[0002] Gantry cranes are widely used in the lifting of various large components and slender structures. In the construction of large factories, bridges, or steel structures, large machinery production workshops generally need to set up gantry cranes to assist in the mobilization and movement of heavy machinery. The cranes usually use traveling wheels at both ends to move the heavy objects horizontally during the lifting process. However, due to the large size and weight of cranes, in order to facilitate relocation and on-site storage, current cranes are usually detachable structures. When assembling the crane, it is necessary to ensure that the traveling wheels at both ends are aligned. If the accuracy is insufficient, there will be a lot of noise during the crane's movement. The current method of assembling the traveling wheels at both ends of the crane is usually to use a measuring tape and manual alignment, which results in low assembly efficiency and difficulty in controlling accuracy. Summary of the Invention

[0024] The crane assembly equipment of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] Reference Figures 1 to 5 As shown, the mobile main beam 40 assembly equipment provided in this embodiment of the invention is used to assemble a crane. The crane includes a main beam 40 and crossbeam frames 41 located at both ends of the main beam. Each crossbeam frame 41 is equipped with a traveling wheel 42. The assembly equipment includes a support rail 10, a fixed component 20, and a moving component 30. The moving component 30 can be controlled to move by an electronic control system to achieve overall digital automatic control. The fixed component 20 is located at the end of the support rail 10 and has a first mounting seat 21 for positioning and installing one set of traveling wheels 42. The moving component 30 is located on the support rail 10 and can move along the length direction of the support rail 10 to approach or move away from the fixed component 20. The moving component 30 has a second mounting seat 31 for positioning and installing another set of traveling wheels 42. The first mounting seat 21 and the second mounting seat 31 are parallel to each other along the length direction. The two sets of traveling wheels 42 can be installed on the same axis to ensure higher installation positioning accuracy.

[0026] Reference Figures 3 to 5 As shown, the first mounting base 21 includes a first fixing part 211 and a first mounting part 212, with the first mounting part 212 protruding from the first fixing part 211. The second mounting base 31 includes a second fixing part 311 and a second mounting part 312, with the second mounting part 312 protruding from the second fixing part 311. The traveling wheel 42 has protruding rims 421 on both sides, which can engage with the sides of the first mounting part 212 and the second mounting part 312, making the traveling wheel 42 more stably installed on the first mounting base 21 and the second mounting base 31. By engaging the rims 421 with the first mounting part 212 and the second mounting part 312, the traveling wheel 42 will not shift position on the first mounting base 21 and the second mounting base 31, resulting in higher installation accuracy. Furthermore, when adjusting the crossbeams 41 on both sides of the main beam 40, the position of the traveling wheel 42 on the first mounting base 21 and the second mounting base 31 can be adjusted to ensure that the two crossbeams 41 are parallel, while also ensuring higher accuracy after the traveling wheel 42 is assembled.

[0027] Reference Figure 2 As shown, the support track 10 includes: a support frame 11, a guide rail 12, and a transmission rack 13. The support frame 11 has two support rods 111 that are parallel to each other along the length direction and a plurality of connecting rods 112 connected between the two support rods 111. The guide rails 12 are respectively disposed on the two support rods 111 and extend along the length direction of the support rods 111. The transmission rack 13 is disposed on at least one support rod 111 and is connected to the moving component 30 in a transmission manner.

[0028] In this embodiment, the fixed component 20 is fixed to one end of the support frame 11, and the movable component 30 is slidably disposed on the guide rail 12. The movable component 30 is connected to the transmission rack 13, thereby controlling the movement of the movable component 30 on the guide rail 12 to control the distance between the movable component 30 and the fixed component 20. Thus, the spacing can be adjusted according to the length of the main beam 40 to ensure higher accuracy during the assembly process of the main beam 40.

[0029] Reference Figure 3 As shown, the fixing assembly 20 includes: a fixing frame 22, a first fixing plate 23, and a first hydraulic cylinder 24. The fixing frame 22 is fixed to the end of the support rail 10. The first fixing plate 23 is disposed on the fixing frame 22 and extends along the width direction of the support rail 10. The first mounting seat 21 is detachably disposed on the first fixing plate 23. The first hydraulic cylinder 24 is disposed on the first fixing plate 23 and is located on the side of the first mounting seat 21. A first pressure block 25 is connected to the first hydraulic cylinder 24. A first screw 26 passes through the first pressure block 25 and can move relative to the first pressure block 25. The first screw 26 is threadedly connected to the first fixing plate 23.

[0030] In this embodiment, there are at least two first hydraulic cylinders 24, each of which abuts against a first pressure block 25. When the crossbeam frame 41 is installed on the first mounting base 21, since the traveling wheels 42 are slidably mounted on the first mounting base 21, the crossbeam frame 41 can be adjusted in position on the first mounting base 21 with the traveling wheels 42. After the position of the crossbeam frame 41 is adjusted during the assembly process, the first hydraulic cylinders 24 can drive the first pressure blocks 25 to press down on the crossbeam frame 41 to keep the position of the crossbeam frame 41 stationary and prevent the crossbeam frame 41 from shifting position as the traveling wheels 42 move. Meanwhile, when the first pressure block 25 presses the crossbeam frame 41, it can be threadedly connected to the first screw 26 through the nut to fix the first pressure block 25 and the first screw 26, ensuring that the first pressure block 25 is pressed more firmly. After the crossbeam frame 41 is installed and fixed, the main beam 40 can be assembled and fixed with the crossbeam frame 41 to ensure simpler and more reliable installation. Optionally, the first fixing plate 23 is provided with a number of first fixing holes 231. The first mounting seat 21 is detachably connected to the first fixing holes 231. By adjusting the position of the first mounting seat 21, the first mounting seat 21 and the second mounting seat 31 can be kept parallel.

[0031] Reference Figure 4 As shown, the movable component 30 includes: a movable frame 32, a second fixed plate 33, a drive motor 34, and a second hydraulic cylinder 35. The movable frame 32 is slidably mounted on the support rail 10; the second fixed plate 33 is mounted on the movable frame 32; the drive motor 34 is mounted on the movable frame 32 and forms a transmission connection with the transmission gear on the support rail 10 through a gear, for driving the movable frame 32 to move along the length direction of the support rail 10; the second hydraulic cylinder 35 is mounted on the second fixed plate 33 and is located on the side of the second mounting base 31. A second pressure block 36 is connected to the second hydraulic cylinder 35. A second screw 37 is provided on the second pressure block 36 and is movable relative to the second pressure block 36. The second screw 37 is threadedly connected to the second fixed plate 33.

[0032] In this embodiment, when determining the length of the main beam 40, the moving frame 32 can be driven by the drive motor 34 to slide on the guide rail 12. After adjusting the distance between the moving frame 32 and the fixed frame 22, and after one of the crossbeam frames 41 is installed on the first mounting base 21, the other crossbeam frame 41 can be installed on the second mounting base 31. When installing the crossbeam frame 41 on the second mounting base 31, since the traveling wheel 42 is slidably mounted on the second mounting base 31, the crossbeam frame 41 can be adjusted in position on the second mounting base 31 with the traveling wheel 42. After the position of the crossbeam frame 41 is adjusted during the assembly process, it can be moved by the second oil... The cylinder 35 drives the second pressure block 36 to press down on the crossbeam frame 41, so as to keep the crossbeam frame 41 in the position of the second mounting seat 31 and prevent the crossbeam frame 41 from shifting position as the traveling wheel 42 moves. At the same time, when the second pressure block 36 presses the crossbeam frame 41, it can be threadedly connected to the second screw 37 through the nut to fix the second pressure block 36 and the second screw 37, so as to ensure that the second pressure block 36 is pressed more firmly. After the crossbeam frame 41 is installed and fixed, the two ends of the main beam 40 can be assembled and fixed with the crossbeam frame 41 on the first mounting seat 21 and the crossbeam frame 41 on the second mounting seat 31, respectively, to ensure simpler and more reliable installation and higher installation accuracy.

[0033] Optionally, the second fixing plate 33 is provided with a plurality of second fixing holes 331, and the second mounting base 31 is detachably connected to the second fixing holes 331, so that the first mounting base 21 and the second mounting base 31 can be kept parallel by adjusting the position of the second mounting base 31, thereby ensuring higher assembly accuracy.

[0034] The mobile main beam 40 assembly equipment provided by this invention is mainly used to assemble the main beam 40. During assembly, the moving component 30 can be driven away from the fixed component 20 according to the length of the main beam 40, so that the distance between the moving component 30 and the fixed component 20 can be adjusted according to the length of the main beam 40. After the adjustment is completed, the traveling wheels 42 on the two crossbeam frames 41 can be respectively installed on the first mounting seat 21 and the second mounting seat 31. The traveling wheels 42 are positioned by the first mounting seat 21 and the second mounting seat 31, which are parallel to each other along the length direction, so that the accuracy of the traveling wheels 42 is more accurate, avoiding manual alignment, making the assembly efficiency higher and improving the assembly accuracy.
