Description

Technical Field

[0001] This utility model belongs to the technical field of excavator accessories, specifically relating to a reinforced foot pedal for excavators. Background Technology

[0002] Currently, excavators are widely used in mining operations in major mines across China. These excavators need to travel on gravel surfaces and are frequently subjected to impacts from rocks. According to standard requirements for the distance between two foot pedals, the foot pedal structure needs to be placed close to the ground, inevitably subjecting the pedals to impacts. Existing foot pedal technology uses bolts to fix them to the lower frame. These bolts are unable to withstand shear impacts, and it is common for the fixing bolts to break after impacts, affecting the safety of the operator when getting in and out of the machine and the overall user experience.

[0003] The existing foot pedal design is prone to failure when subjected to impacts from the front or rear of the machine, causing the fixing bolts to break off. Utility Model Content

[0004] To address the problems of existing technologies, a reinforced foot pedal for excavators is proposed to prevent the fixing bolts from being subjected to large shear forces and to solve the problem of bolts being easily cut off. This utility model provides the following technical solution:

[0005] A reinforced foot pedal for an excavator includes a foot panel for providing foot support and a fixing screw seat for connecting to the frame; connecting plates are connected to the left and right sides of the foot panel, forming an installation space between the foot panel and the connecting plates on both sides; fixing plates are connected to the connecting plates on both sides within the installation space; the fixing plates are provided with transversely extending elongated holes; the fixing screw seat is provided with mounting holes; the fixing plates are threaded into the mounting holes by bolts passing through the elongated holes, thereby achieving connection with the fixing screw seat.

[0006] Preferably, a first load-bearing plate for improving impact resistance is fixedly connected to the left fixing plate, and a second load-bearing plate for improving impact resistance is fixedly connected to the right fixing plate, with two fixing screw seats located between the first load-bearing plate and the second load-bearing plate.

[0007] Preferably, the lateral distance between the first force-bearing plate and the second force-bearing plate is greater than the external lateral dimension of the two fixing screw seats.

[0008] Preferably, the first force-bearing plate abuts against the left-side fixing screw seat, and the second force-bearing plate is clearance-fitted with the right-side fixing screw seat.

[0009] Preferably, the gap between the second force-bearing plate and the fixing screw seat on the right side is 0.5-2mm.

[0010] Preferably, a reinforcing rib plate is fixedly connected to the foot pedal panel, and the reinforcing rib plate is connected to the connecting plates on both sides of the foot pedal panel.

[0011] Preferably, the footrest panel has a positioning hole in the middle for placing a foot.

[0012] Preferably, the bottom of the positioning hole is provided with a first tooth groove, and the upper end of the foot pedal panel is provided with a second tooth groove.

[0013] Preferably, each fixing plate is provided with three elongated holes, and each fixing screw seat is provided with three mounting holes.

[0014] Preferably, the elongated holes on each fixing plate are arranged at equal intervals vertically, and the mounting holes on each fixing screw seat are arranged at equal intervals vertically.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By using the design of the elongated hole and the bolt to fit together, the shear force is converted into a lateral displacement buffer, which significantly reduces the risk of bolt breakage due to shear and improves the reliability of the connection;

[0017] 2. By adding load-bearing plates and reinforcing ribs, the overall impact resistance and strength are improved, ensuring the stable operation of the excavator in complex environments;

[0018] 3. The bolts are located within the installation space and are protected by the foot panel and connecting plate during daily use, thereby increasing their service life and reducing the frequency of maintenance required. Attached Figure Description

Detailed Implementation

[0025] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0026] like Figure 1-5 As shown, a reinforced foot pedal for an excavator includes a foot panel 1 for providing foot support and a fixing screw seat 4 for connecting to the frame 10. In this embodiment, the direction facing the foot panel 1 is used as the viewing reference, and the direction the front of the machine faces is the left side of the foot panel 1. The most common impact is an impact from the forward direction during the movement of the whole machine, that is, an impact from the left and right direction in this embodiment. The foot panel 1 is connected to the left and right sides with connecting plates 2, forming an installation space between the foot panel 1 and the connecting plates 2 on both sides. The connecting plates 2 on both sides are connected to fixing plates 3 within the installation space. The fixing plates 3 are provided with transversely extending elongated holes 31, and the fixing screw seat 4 is provided with installation holes. The fixing plates 3 are threaded to the installation holes by bolts 5 passing through the elongated holes 31. When impacted, the shear force from the fixing plates 3 on the bolts 5 is greatly reduced, preventing the bolts 5 from being cut off, achieving a reliable connection with the fixing screw seat 4. Moreover, the bolts 5 are located within the installation space and can be protected by the foot panel 1 and connecting plates 2 during daily use, thereby improving service life and reducing the required maintenance frequency.

[0027] Specifically, the connecting plate 2 and the footrest panel 1 are integrally formed. The footrest panel 1 has a positioning hole 11 in the middle for placing a foot, a first toothed groove 12 at the bottom of the positioning hole 11, and a second toothed groove 13 at the top. Each fixing plate 3 has three elongated holes 31, and each fixing screw seat 4 has three mounting holes. The elongated holes 31 on each fixing plate 3 are evenly spaced vertically, and the mounting holes on each fixing screw seat 4 are also evenly spaced vertically. To improve the connection strength, a washer 51 is provided on the fixing plate 3 to cooperate with the bolt 5.

[0028] Furthermore, a first force-bearing plate 61 for improving impact resistance is fixedly connected to the left fixing plate 3, and a second force-bearing plate 62 for improving impact resistance is fixedly connected to the right fixing plate 3. Two fixing screw seats 4 are located between the first force-bearing plate 61 and the second force-bearing plate 62. The lateral distance between the first force-bearing plate 61 and the second force-bearing plate 62 is greater than the external lateral dimension of the two fixing screw seats 4. The first force-bearing plate 61 abuts against the left fixing screw seat 4, and the second force-bearing plate 62 is clearance-fitted with the right fixing screw seat 4. Specifically, the gap between the second force-bearing plate 62 and the right fixing screw seat 4, i.e., the distance L8, is 0.5-2mm, while the force-bearing plate and the fixing screw seat 4 have zero gap. Thus, in most cases, the impact force is directly transmitted to the side of the fixing screw seat 4, reducing the degree of impact.

[0029] Furthermore, a reinforcing rib plate 7 is fixedly connected to the foot pedal panel 1. The reinforcing rib plate 7 is horizontally arranged and connected to the connecting plates 2 on both sides of the foot pedal panel 1 to ensure the strength of the lower area that is prone to impact and prevent deformation due to impact.

[0030] Specifically, a rectangular groove 41 is cut on the fixing screw seat 4 to avoid the weld seams on both sides of the first force plate 61 and the second force plate 62, so as to arrange the weld points 9 and improve the feasibility of the scheme.
