[0032] like Figures 1-2 As shown, a novel end beam fixing structure for a crane includes symmetrically arranged end beams 1 and a connecting frame 2 disposed between the two end beams 1. Fixing components 3 for fixing the connecting frame 2 to the end beams 1 are symmetrically arranged within the connecting frame 2.

[0033] like Figures 1-2 As shown, the two end beams 1 have first boring holes on their corresponding end sides that are adapted to the fixing component 3. The lower surface of the end beam 1 is fixedly mounted with a fixing plate 11 by bolts. The fixing plate 11 is used to enhance the support performance of the end beam 1.

[0034] like Figures 3-4 As shown, in this embodiment, the connecting frame 2 is U-shaped, which facilitates installation onto the end of the end beam 1. Two sets of second boring holes are symmetrically opened on both sides of the connecting frame 2. The second boring holes of the connecting frame 2 correspond to the positions of the first boring holes of the end beam 1, which facilitates connection with the fixing component 3.

[0035] As Figures 3-4 shown in the embodiment, annular grooves 22 are opened at the positions of the second bore holes in the inner walls on both sides of the connecting frame 2, and rubber gaskets 32 are installed in the annular grooves 22, which can improve the connecting effect of the connecting frame 2 and the end beam 1.

[0036] As Figures 3-4 shown in the embodiment, welding interfaces 21 are symmetrically opened in the upper end faces of the connecting frame 2, and pull plates 4 are welded and fixed in the welding interfaces 21. After the pull plates 4 are welded in the welding interfaces 21, gaps are left between the lower surfaces on the outer sides of the pull plates 4 and the upper end faces of the end beam 1, which facilitates the separation of the connecting frame 2 and the end beam 1 by pulling the pull plates 4.

[0037] As Figures 4-8 shown in the embodiment, the fixing assembly 3 includes stepped connecting shafts 31, a sealing cover 33, and two symmetrically arranged arc-shaped metal clamping plates 5 that can be butt-jointed together. The connecting shafts 31 are adapted to the first bore holes and the second bore holes, and the end faces of one end of the connecting shafts 31 are provided with stop covers, and the surfaces of the other end are provided with annular clamping grooves 311 that are adapted to the clamping plates 5.

[0038] Specifically, after the connecting frame 2 is installed between the two end beams 1, the positions of the first bore holes and the second bore holes correspond to each other at this time, then the two connecting shafts 31 are penetrated through the first bore holes and the second bore holes to connect the connecting frame 2 and the end beam 1 together, until the stop cover at one end of the connecting shaft 31 is in close contact with the side face of one side of the connecting frame 2, and at this time, the clamping groove 311 on the surface of the other end of the connecting shaft 31 corresponds to the position of the side face of the other side of the connecting frame 2, at this time, the two arc-shaped clamping plates 5 can be installed in the clamping groove 311.

[0039] As Figures 4-8 shown in the embodiment, four bolt grooves 23 are opened in the outer side face of one side of the connecting frame 2, the bolt grooves 23 do not penetrate through the connecting frame 2, and the bolt grooves 23 are circumferentially arranged around the second bore hole and correspond to the positions of the clamping plates 5.

[0040] As Figures 4-8 shown in the embodiment, the surfaces of the clamping plates 5 are provided with counterbores 51 corresponding to the bolt grooves 23, the counterbores 51 are provided with counterbores 51, the upper end faces of the lower clamping plates 5 are symmetrically and fixedly provided with clamping blocks 52, the lower end faces of the upper clamping plates 5 are symmetrically provided with butt-joint grooves 53, and the positions of the clamping blocks 52 and the butt-joint grooves 53 correspond to each other to enable the butt joint of the two clamping plates 5.

[0041] Specifically, after the two clamping plates 5 are installed in the clamping groove 311, the counterbores 34 are threadedly matched with the bolt grooves 23 to fixedly connect the clamping plates 5 and the connecting frame 2 together, and after the fixing is completed, the clamping plates 5 will limit the positions of the connecting shafts 31 so that they will not self-rotate.

[0042] As Figure 5 shown in the embodiment, the circumferential surface of the clamping plate 5 is provided with a notch 54 and an arc-shaped groove 55, the arc-shaped groove 55 is communicated with the notch 54, and a metal protrusion 56 is symmetrically and fixedly arranged at the position of the arc-shaped groove 55 close to the inner wall.

[0043] As Figure 6 shown, the sealing cover 33 is made of plastic as a whole, and a top block 331 is symmetrically and fixedly arranged at the inner wall of the sealing cover 33, the top block 331 is matched with the notch 54 and the arc-shaped groove 55.

[0044] Specifically, after the clamping plate 5 is fixed with the connecting shaft 31 and the connecting frame 2, the sealing cover 33 is sleeved on the connecting shaft 31, at this time the top block 331 enters the notch 54, then the sealing cover 33 is rotated to make the top block 331 enter the arc-shaped groove 55, until the top block 331 contacts with the protrusion 56, then the metal protrusion 56 extrudes the plastic top block 331, until the top block 331 enters the position on the other side of the protrusion 56, at this time the protrusion 56 limits the top block 331, that is, the assembly of the sealing cover 33 is completed.

[0045] Further, the sealing cover 33 can effectively block dust and water stains, and protect the clamping plate 5 and the countersunk bolt 34, so as to avoid the inconvenience of subsequent disassembly due to long time.
