Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a truck with a pipe protection frame for mounting an engine.

[0002]

[Premise structure]

 The trolley with a pipe protection frame for mounting an engine of the present invention is assumed to have the following premise structure as shown in FIG. 5, for example. That is, the pipe 1 is framed into a box to form a box-shaped pipe protection frame 2. A horizontal frame 4 for supporting equipment is mounted between the lower left and right frames 3a and 3b located on the left and right sides of the lower part of the pipe protection frame 2. Then, a pair of left and right wheels 5a and 5b are arranged near the left and right ends of the horizontal frame 4, respectively.

[0003]

[Prior Art]

 In the above-mentioned premise structure, as a structure in which the wheels 5a and 5b are detachably attached to the pipe protection frame 2, there are conventional structures shown in FIGS. 5 and 6. That is, the axle 16 runs parallel to the lower side of the horizontal frame 4 via the bearing plate 15 and is fixed by the shaft retainer 17, the bolt 18 and the nut 19. The wheel pivot shaft portions 6a and 6b at both the left and right ends of the axle 16 are made to project laterally outward through the lower side of the lower left and right frames 3a and 3b. The vehicle wheels 5a and 5b are rotatably supported by the wheel pivot shaft portions 6a and 6b on the lateral outer sides of the lower left and right frames 3a and 3b, and are prevented from coming off by a retaining ring 20.

[0004]

[Problems to be solved by the device]

 The above conventional technique has the following problems. (A) Since the horizontal frame 4 is located higher than the axle 16, the ground height of the engine 10 supported on the horizontal frame 4 becomes high, and the horizontal vibration of the vehicle due to the horizontal vibration component of the engine 10 is large. .. (B) Since the lower left and right frames 3a and 3b are located higher than the axle 16, the height of the bogie becomes high. Moreover, since the axle 16 projects laterally outward, the lateral width of the truck becomes wider. (C) In order to pivotally support each wheel 5a, 5b, the structure is complicated and heavy because the axle 16, bearing plate 15 and shaft retainer 17 are required. An object of the present invention is to reduce the rolling of the bogie due to engine vibration, downsize the bogie, and simplify the structure for pivotally supporting the wheels.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention adds the following improved structure to the above-mentioned premise structure, as shown in, for example, FIG. 1 to FIG. 3 or FIG. That is, inside the left and right lower left and right frames 3a and 3b, the wheel pivot shaft portions 6a and 6b are formed at the left and right frame ends 4a and 4b of the horizontal frame 4, respectively. Each of the pair of left and right wheels 5a and 5b is formed by fixing a pair of semicircular wheel halves 7a and 7b in a circular shape and fixing them by fixing means 8. The pair of left and right wheels 5a and 5b composed of the pair of wheel halves 7a and 7b are attached to the wheel pivot shaft portions 6a and 6b of the left and right frame end portions 4a and 4b of the horizontal frame 4, respectively. It is rotatably supported.

[0006]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. (A) Since the horizontal frame 4 can be lowered to almost the same height as the wheel pivot shafts 6a and 6b, the ground height of the engine 10 supported on the horizontal frame 4 becomes low, and the engine 10 Rolling of the bogie due to the horizontal vibration component is reduced. (B) Since the horizontal frame 4 and the lower left and right frames 3a and 3b can be lowered to almost the same height as the wheel pivot shaft portions 6a and 6b, the height of the carriage is reduced. Moreover, since the wheel pivot shaft portions 6a and 6b and the wheels 5a and 5b enter inside the lower left and right frames 3a and 3b, the lateral width of the truck is reduced. This makes the cart smaller. (C) As a structure for pivotally supporting the wheels 5a and 5b, since the wheel pivot shaft portions 6a and 6b are formed at the left and right frame end portions 4a and 4b of the horizontal frame 4, respectively, The axle 16, bearing plate 15 and shaft retainer 17 can be omitted. As a result, the wheel pivot structure can be simplified and the weight can be reduced.
