Description

Technical Field

[0001] The utility model relates to a channel structure and belongs to the technical field of engineering machinery excavators. Background Art

[0002] Generally, large excavators on the market are relatively high, and when climbing onto the excavator, you need to climb up and down through the passage in front of the slewing platform. However, when the excavator is operating, when the slewing platform and the chassis are not in the same position, that is, at an angle, it is inconvenient to climb the excavator through the passage, and the passage is single.

[0003] In the existing technical solution, the passage is at the tool box. When going up and down the passage, you need to use the chassis crawler as a platform, which is very inconvenient. First, you need to step on the pedal at the chassis, and then use the crawler plate and the pedal at the tool box to pass through the passage. During the whole process, passing through the passage requires not only leg strength, but also the pulling force of the hands to go up, which is very inconvenient. Summary of the invention

[0029] like Figure 1 As shown, a passage structure includes a base plate 1, a pair of foldable components opposite to each other and at least one pedal 12; the base plate 1 is connected to the counterweight on the frame; a pair of foldable components opposite to each other are respectively connected to the two sides of the base plate 1; at least one pedal 12 is installed between the two foldable components in an upper and lower interval and staggered manner, on the one hand, it can be folded together with the foldable components for storage, and on the other hand, it can be unfolded together with the foldable components, and the bottom height position of the counterweight can be reached through the pedal 12, and then the escalator on the counterweight can be used for passage.

[0030] A preferred embodiment of the above embodiment regarding the foldable component is given below:

[0031] Continue to refer to Figure 1 As shown, the foldable assembly is mainly composed of a plurality of hinged side panels 4, 7, 8, 11 and connectors. The number of side panels is 2n, where n is a positive integer. Two adjacent side panels are hinged together through a pin 3, wherein the other end of the first side panel 4 is hinged to the support 3 on the bottom panel 1 through a pin 3; a pedal 12 has a connector and two side panels on each side, thereby forming a set of step structures. When the connector is fully extended, the two side panels on both sides of the pedal 12 form a 90-degree angle, and the pedal 12 is located between the two side panels in a horizontal state; when the connector is removed, the pedal 12 and the two side panels in a horizontal state can be flipped upward 90 degrees together and folded together with the two vertical side panels. Finally, multiple step structures can be folded together.

[0032] It should be noted that two sets of step structures are provided in this embodiment. Of course, in actual use, it is not limited to two sets of step structures, and the number of steps can be increased according to the actual counterweight height.

[0033] A further solution is that an anti-rotation component is installed between the side panels 7 of one set of step structures in a horizontal state and the side panels 8 of the other set of step structures in a vertical state, to prevent the two sets of step structures from shaking.

[0034] Preferred solution: The anti-rotation component is composed of a pin shaft 13 and a cotter pin. The pin shaft 13 is inserted into the non-hinge point position of the two side plates 7 and 8, and is axially limited by the cotter pin.

[0035] Continue to refer to Figure 1 As shown, the connecting piece is composed of two connecting rods 5, 6, 9, 10 hinged together, and a pin is fixed to the inner side surfaces of both ends of the two connecting rods hinged together. A socket I is provided on the side plate. When the two side plates are at an angle of 90 degrees, the pins at both ends of the connecting piece can be respectively inserted into the corresponding socket I and axially fixed by a cotter pin, and the two side plates are maintained at a 90-degree angle by the connecting rod.

[0036] A further solution is that each of the side panels 4, 7, 8, 11 is provided with a socket II. When all of the side panels 4, 7, 8, 11 are folded together, the pin 13 is inserted into all of the sockets II and axially limited by a cotter pin.

[0037] A preferred solution is that the pedal 12 is composed of a plurality of coplanar and evenly spaced flat plates.

[0038] Continue to refer to Figure 1As shown, the channel structure is bilaterally symmetrical. The bottom plate 1 can be welded under the counterweight as part of the counterweight, or the four holes of the bottom plate 1 can be connected to the bottom of the counterweight. The support 2 is welded and fixed to the bottom plate 1. When working, the side plates 4, 7, 8, and 11 are unfolded in sequence and connected by the pin 3, and the side connecting rods 5, 6, 9, and 10 of the side plates are also connected to the side by the pin. A set of pedals 12 are connected in the middle of the side plates on both sides of the channel, and the pedals 12 are welded to the side plates on both sides.

[0039] When the channel is unfolded, when a person stands on the pedal 12, the gravity of the person is pulled by the side connecting rods 5, 6, 9, and 10 to reach a balanced state. At this time, the person can step on the channel to reach the bottom height of the counterweight, and then use the escalator designed on the counterweight to pass (the counterweight escalator needs to be designed at the same time). In order to avoid shaking between the side panels 7 and 8, they can be connected by a pin shaft 13. At this time, the stress state of the entire channel is no different from that of a fixed channel.

[0040] When the channel is not in use, the pin 13 and the side connecting rods 5, 6, 9, 10 can be taken out, and then the entire channel can be folded up, and the pin 13 can be inserted into the middle mounting hole of the side plates 4, 7, 8, 11 to be fixed.

[0041] The utility model also discloses an excavator, comprising a counterweight, on which the channel structure is installed.

[0042] In the description provided herein, a large number of specific details are described. However, it is understood that embodiments of the present invention can be practiced without these specific details.
