DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A shock-resistant large excavator left and right platforms, including a main platform 1, with a left platform 2 and a right platform 3 respectively attached to the two sides of the main platform 1, the left platform 2 and the right platform 3 are both fixed to the side of the main platform 1 through a connecting mechanism, the connecting mechanism includes a bottom reinforcing rib 4, an angle steel 5 and a receiving groove 6, two bottom reinforcing ribs 4 are welded to the bottom of the main platform 1, the receiving grooves 6 are respectively arranged at the bottom of the left platform 2 and the right platform 3, one end of the bottom reinforcing rib 4 extends to the inside of the receiving groove 6 and is fixed in the receiving groove 6 through a locking assembly, the angle steel 5 is anti-shock The striking bolts are fixed at the connection between the main platform 1 and the left platform 2, and the main platform 1 and the right platform 3. A support plate 19 is vertically welded between the two bottom reinforcement ribs 4. The support plate 19 is attached to the bottom of the left platform 2 and the right platform 3. The locking assembly includes a drive plate 7, a connecting plate 8, a clamping block 9 and a locking hole 10. The drive plate 7 is movably arranged on the side of the bottom reinforcement rib 4 through a traction mechanism, the connecting plate 8 is fixed on the drive plate 7, the clamping block 9 is fixed on the connecting plate 8, the locking hole 10 is arranged on the inner wall of the accommodating groove 6, and the clamping block 9 extends into the locking hole 10.

[0029] See also Figure 1 , 2 And 3, when one end of the block 9 moves to the inside of the locking hole 10, the vertical direction of the block 9 is limited, so that the vertical limitation between the bottom reinforcement rib 4 and the left platform 2 or the right platform 3 can be achieved. The bottom reinforcement rib 4 serves as a skeleton connecting the left platform 2 and the right platform 3, which increases the contact area between the left platform 2 and the right platform 3 and the main platform 1, while improving the overall connection strength.

[0030] The traction mechanism includes a connecting arm 11, a traction seat 12, a driving rod 13 and a slide groove 14. The slide groove 14 is arranged on the surface of the bottom reinforcement rib 4. The traction seat 12 is slidably arranged inside the bottom reinforcement rib 4. One side of the traction seat 12 is slidably arranged in the slide groove 14. The two ends of the connecting arm 11 are respectively hinged to the side surface of the traction seat 12 and one end of the driving plate 7. The driving rod 13 is rotatably arranged inside the bottom reinforcement rib 4. A two-way thread is arranged on the driving rod 13. The traction seat 12 is connected to the driving rod 13 through the two-way thread. One end of the driving rod 13 is provided with a hexagonal groove 17. Two connecting seats 18 are fixed to one end of the driving plate 7 and the side surface of the traction seat 12. One end of the connecting arm 11 is rotatably arranged between the two connecting seats 18 through a pin shaft.

[0031] See also Figure 5 and 6The driving rod 13 can be directly rotated by a hexagonal wrench. When the driving rod 13 rotates, the two traction seats 12 can be driven to move closer to or away from each other through the bidirectional thread on its surface. When the two traction seats 12 are close to each other, the traction seat 12 can drive one end of the connecting arm 11 to move synchronously through the connecting seat 18, and the other end of the connecting arm 11 will squeeze the driving plate 7 to move in a direction away from the bottom reinforcing rib 4. When the two traction seats 12 are away from each other, the other end of the connecting arm 11 will stretch the driving plate 7 to move in a direction close to the bottom reinforcing rib 4 to drive the connecting plate 8. When the connecting plate 8 moves, it can drive the block 9 to move synchronously inside the locking hole 10 to achieve the connection and separation between the block 9 and the locking hole 10.

[0032] It should be noted that the hexagonal groove 17 can also be set as a groove matching the crank, and the driving rod 13 can be driven by the crank and similar tools. For the movement process of the driving plate 7, the driving plate 7 Figure 3 In order to separate the block 9 from the locking hole 10, the driving plate 7 needs to move the same distance as the depth of the locking hole 10, and the traction seat 12 needs to move in a certain proportion under the transmission of the connecting arm 11. Figure 3 The illustrations are only for reference of working principle and are not true to scale.

[0033] Embodiment 2:

[0034] In the above scheme, the driving plate 7 can be driven to move horizontally through the traction mechanism, so as to realize the locking between the connecting plate 8 and the accommodating groove 6. However, for the driving plate 7, its movement process cannot be offset. Therefore, in this embodiment, a guide assembly is arranged between the driving plate 7 and the bottom reinforcement rib 4. The guide assembly includes a fixed seat 15 and a movable seat 16. The fixed seat 15 is installed on the side of the bottom reinforcement rib 4, and the movable seat 16 is installed on the side of the driving plate 7, and one end of the movable seat 16 is elastically movably arranged inside the fixed seat 15.

[0035] See also Figure 3 When the driving plate 7 moves, it can drive the movable seat 16 to move synchronously inside the fixed seat 15. Since the fixed seat 15 can limit the movement process of the movable seat 16, the fixed seat 15 can also limit the movement process of the driving plate 7, so that the driving plate 7 will not be offset during the translation process, so as to ensure the precise alignment between the block 9 and the locking hole 10.

[0036] Working principle: first, the left platform 2 and the right platform 3 are hoisted on both sides of the main platform 1. The bottom reinforcement rib 4 extends to the inside of the accommodating groove 6 at this time. Then, the driving rod 13 is directly rotated by a hexagonal wrench. When the driving rod 13 rotates, the two traction seats 12 can be driven to approach each other through the bidirectional thread on its surface. At this time, the traction seat 12 can drive one end of the connecting arm 11 to move synchronously through the connecting seat 18, and the other end of the connecting arm 11 will squeeze the driving plate 7 to move in a direction away from the bottom reinforcement rib 4. When the driving plate 7 moves, it can drive the block 9 to move synchronously through the connecting plate 8. When one end of the block 9 moves to the inside of the locking hole 10, the vertical direction of the block 9 is limited.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
