Detailed Description
The excavator guard rail according to the present invention will be described in detail below with reference to the accompanying drawings.
First embodiment
An excavator guard rail 10 according to a first embodiment of the present invention will be described with reference to fig. 1 to 6.
Fig. 1 is a perspective view showing a cab of an excavator to which an excavator guard rail according to a first embodiment of the present invention is applied, fig. 2 is a perspective view showing the excavator guard rail according to the first embodiment of the present invention, fig. 3 is an exploded perspective view in which a foot pedal cover is separated from fig. 2, fig. 4 is a cut perspective view of a foot pedal in fig. 2, fig. 5 is an enlarged perspective view showing a portion a of fig. 2, and fig. 6 is a perspective view showing a state in which a fire extinguisher is installed in fig. 5.
As shown in fig. 1, the excavator guard rail 10 of the present embodiment is fixedly provided in the cab 20 in front of the driver.
As shown in fig. 2, the excavator guard rail 10 of the present embodiment includes a pipe portion 100, a foot pedal 200, and a fire extinguisher mounting portion 300.
The tube portion 100 includes a first tube 110, a second tube 120, a bent portion 130, and a third tube 140.
In this case, the first pipe 110, the second pipe 120, and the bent portion 130 do not mean that they are different members. That is, the terms of the first tube 110, the second tube 120, the bent portion 130, and the like are only used as terms according to the position and shape of each portion for convenience of description, and do not mean that these are separable and independent components. For example, the first tube 110, the second tube 120, and the bent portion 130 may be manufactured by bending a single tube member.
The first pipe 110 is located on the upper side of the pipe portion 100 in a direction parallel to the floor of the cab. The bent portions 130 are formed at both side end portions of the first pipe 110, and the bent portions 130 are perpendicularly bent and extended toward the second pipe 120.
The second pipe 120 is positioned at both sides, one on each side, and coupled to the cab floor through a mounting plate 150. The mounting plate 150 is coupled to the cab floor while being welded to the second pipe 120.
The second pipe 120 is joined to the cab floor, and a damper plate 160 is provided between the second pipes 120. The damping plate 160 serves to damp vibration and prevent vibration generated from the excavator from being directly transmitted to the pipe part 100, thereby firmly fixing the excavator guard 10.
The third pipe 140 is parallel to the cab floor. That is, the third pipe 140 is parallel to the first pipe 110. The third pipe 140 is positioned between the two second pipes 120, and both side ends of the third pipe 140 are coupled to the second pipes 120. The third pipe 140 and the second pipe 120 may be joined by welding.
The third pipe 140 is provided with a foot pedal 200. The foot pedals 200 are provided in a pair to correspond to both feet of the driver, and the foot pedals 200 are spaced apart from each other. The third pipe 140 functions as a kind of cross rib between the second pipes 120, so that the overall rigidity of the pipe portion 100 can be improved.
Considering that the foot pedal 200 is provided, the height of the third pipe 140 is determined to be a height comfortable for the driver to put his foot thereon.
The foot pedal 200 is inclined so that a driver can comfortably put his foot thereon. The foot pedal 200 is similar to an operation pedal (brake, accelerator, etc.) widely used for traveling operation of a construction machine or a vehicle. However, unlike the operating pedal, the foot pedal 200 is firmly fixed to prevent the foot pedal from being pressed, thereby stably supporting the body of the driver.
The pedal 200 includes a pedal bracket 210 and a pedal cover 220. The pedal bracket 210 is a part fixed to the third pipe 140. Referring to fig. 4, the footrest bracket 210 includes a first portion 212 and a second portion 214. The second portion 214 has a flat plate shape, and the first portion 212 is coupled to upper and lower sides of the second portion 214.
The footboard cover 220 is coupled to the footboard bracket 210 in an interference fit manner. The pedal cover 220 is made of a highly elastic rubber material, so that the driver's foot does not easily slip when contacting the pedal cover 220. In order to increase the frictional force, the surface of the pedal cover 220 may be formed with irregularities.
The second pipe 120 is provided with a fire extinguisher mounting part 300. The fire extinguisher mounting part 300 is formed with a fastening hole 302 for coupling with a fire extinguisher bracket 410. As shown in fig. 6, the fire extinguisher bracket 410 is used to fix the fire extinguisher 400, and is coupled and fixedly provided to the fastening hole 302 by a screw.
The operation and effect of the excavator guard rail 10 of the present embodiment will be described below.
According to the present embodiment, the step 200 is provided in the pipe portion 100, so that the driver can perform work in a stable posture on an inclined surface. Therefore, driving convenience is improved.
In a conventional excavator without a footrest, a driver can maintain balance by placing his or her feet on the guard rail pipe portion, but since the surface of the pipe portion is curved, the area of contact with the feet is small and the pipe portion is easy to slide, and sufficient frictional force cannot be secured. Therefore, the driver can only perform work in a very unstable posture. However, in the present embodiment, the foot pedal 200 is provided so that the driver can put his or her feet thereon to support his or her body, thereby solving such a problem.
Second embodiment
An excavator guard rail 10' according to a second embodiment of the present invention will be described with reference to fig. 7 to 9.
Fig. 7 is a perspective view showing a cab of an excavator to which an excavator guard rail according to a second embodiment of the present invention is applied, fig. 8 is a perspective view showing the excavator guard rail according to the second embodiment of the present invention, and fig. 9 is a perspective view of a portion B of fig. 8 viewed from another angle.
A detailed description of the common parts with the foregoing first embodiment will be omitted below.
In the second embodiment, the first tube 110 ' is formed shorter than the third tube 140 ', and the third tube 140 ' includes the interference avoiding zone B. The reason for having such a structure is to prevent the swing motion of the boom from being interfered by the excavator guard rail 10' during the front operation of the excavator. Due to the small size of the whole body and the small space of the cab, the guardrail of the super-small excavator may overlap with the rotary motion path of the movable arm. Therefore, as shown in the present embodiment, when the first pipe 110' is formed in a small length and is located only at one side, the other side may form a space for allowing the swing motion of the boom without interference.
However, in the present embodiment, unlike the first pipe 110 ', the length of the third pipe 140' having the footrest 200 is difficult to be greatly reduced. Since the foot pedal 200 should be spaced apart with a gap between both feet according to the physical condition of the driver, the foot pedal 200 is directly coupled to the third pipe 140'. In this case, the swing motion of the boom may still be disturbed by the third pipe 140' in the subminiature excavator. To solve such a problem, the third tube 140' of the present embodiment is formed with an interference avoiding section B.
As shown in fig. 9, the interference avoiding section B is formed with a pressing portion 142 that reduces the volume by pressing the third pipe 140' flatly. The pressing part 142 is formed in a swing movement section of the boom with a thickness thinner than other portions of the third pipe 140 'so as to minimize interference of the third pipe 140' with the boom.
Third embodiment
An excavator guard rail according to a third embodiment of the present invention will be described with reference to fig. 10 to 12.
Fig. 10 is a perspective view showing a footrest and its periphery according to a third embodiment of the present invention, fig. 11 is a perspective view showing a state where a footrest cover is removed in fig. 10, and fig. 12 is an exploded perspective view showing a footrest bracket separated in fig. 11.
A detailed description of the common parts with the foregoing first embodiment will be omitted below.
In the third embodiment, the foot pedal 200 ″ can be provided to move left and right. Since the drivers of the excavator have different physical conditions and the intervals most comfortable when the feet are placed on the footrests 200 ″ are different, the drivers need to set the intervals suitable for themselves. For this reason, in the present embodiment, the position where the foot board 200 ″ is provided is adjusted left and right, so that the driver can select an interval suitable for the excavator driver.
To achieve such an object, the pedal 200 ″ of the third embodiment includes a pedal mounting portion 202, a pedal bracket 210, and a pedal cover 220.
The pedal plate mounting portion 202 has a plurality of screw holes 202a formed therein. The screw holes 202a are spaced at predetermined intervals. On the other hand, in the present embodiment, the number of the screw holes 202a is 4, but the number and the interval may be different from this.
As shown in fig. 12, a plurality of fastening holes 212a are formed in the first portion 212 of the pedal bracket 210. The fastening holes 212a are formed at the same interval as the screw holes 202 a. The pedal bracket 210 is coupled to the pedal mounting portion 202 by a bolt that penetrates the fastening hole 212a and the screw hole 202a together. For stable bolt coupling, the fastening holes 212a are preferably formed in 2. At this time, the footboard 200 ″ can be horizontally moved only if the number of the screw holes 202a is greater than the number of the fastening holes 212 a. The movable placement of the foot pedal 200 "will be described later.
The second portion 214 of the footrest bracket 210 has a plurality of holes 214a formed therein. The hole 214a is formed at a position corresponding to the fastening hole 212a, but has a larger diameter than the fastening hole 212 a. The hole 214a provides a space for inserting a fastening tool such as a screwdriver for bolt coupling.
The following describes a process of movably disposing the foot pedal 200 ". First, in order to dispose the pedal 200 ″ on the left side, the 2 fastening holes 212a are located at positions corresponding to the 2 screw holes 202a formed on the left side, and then the pedal bracket 210 is fixed to the pedal mounting portion 202 by bolt coupling. On the contrary, in order to set the footboard 200 "on the right side, the 2 fastening holes 212a are positioned on the 2 screw holes 202a formed on the right side, and the footboard bracket 210 is fixed to the footboard mounting part 202 by bolt coupling. Through the above process, the driver can easily adjust the interval of the foot pedals 200 ″.
