Problems solved by technology

[0004] The purpose of the present invention is to solve the deficiencies in the prior art, and to invent a locomotive counterweight and a method for adjusting the weight and center of gravity of locomotives with different axle load conversions, so as to adapt to the situation that the installation weight of the equipment is not completely symmetrical about the center of the locomotive According to the user's personalized equipment installation requirements, without changing the locomotive body, it can quickly and conveniently meet the locomotive curb weight requirements, locomotive axle load and wheel weight balance, and can save the installation space in the machine room

Embodiment 1

[0028] Such as figure 1 As shown, a locomotive counterweight includes a fixed counterweight 10, the lower part of the fixed counterweight 10 is connected with the machine room equipment mounting seat of the car body 14 through a connecting structure, and the upper part of the fixed counterweight 10 is provided with 2 An adjustable counterweight 11 with the same weight, a cover plate 12 is installed on the top of the adjustable counterweight 11, and the adjustable counterweight 11 and the cover plate 12 are installed on the fixed counterweight 10 with fasteners 13 through the same mounting holes. superior.

[0029] The weight of the fixed counterweight 10 accounts for 90% of the weight of the locomotive counterweight, and the weight of each adjusting counterweight 11 accounts for 5% of the weight of each counterweight of the locomotive.

[0030] The fastener 13 is a bolt, which is installed on the fixed counterweight 10 to adjust the counterweight 11 and the cover plate 12 . ...

Embodiment 2

[0032] A method for adjusting the weight and center of gravity of locomotives with different axle load conversions. A certain 2 (B0-B0) axle locomotive needs to realize the conversion of 30-ton axle load and 27-ton axle load. When the axle load is 30 tons, the curb weight is (The curb weight of each locomotive ), curb weight at 27 tons axle load (The curb weight of each locomotive ). According to the state of axle load of 27 tons during design, the curb weight of each locomotive is 107.5 tons, and the total weight of counterweight is 12 tons, which becomes the state of axle load of 30 tons (the curb weight of each locomotive is 119.5 tons). The locomotive counterweight is divided into 6 pieces, adopting the locomotive counterweight in Embodiment 1, and the reference weight of each locomotive counterweight is 2 tons, wherein each counterweight is a fixed counterweight 10, The adjustment counterweight 11 that two single weights are 0.1 ton is formed.

Abstract

The invention relates to a locomotive counterweight and a weight and center-of-gravity adjusting method for changing different axial loads of a locomotive through the locomotive counterweight. The locomotive counterweight comprises a fixed counterweight; the lower portion of the fixed counterweight is connected with a machine room equipment mount of a locomotive body through a connection structure; adjustable counterweights connected in a detachable manner are arranged on the upper portion of the fixed counterweight. According to the weight and center-of-gravity adjusting method, locomotive service weight, axle load and wheel load are detected, and the locomotive counterweight is adjusted in various ways according to detection results. The self-weight and center-of-gravity of the locomotive counterweight which is convenient to mount are convenient to adjust, so that the requirement for locomotive weight and the requirement for axle load and wheel load balance are accurately met; during installation of user-customized devices, the requirement for the locomotive service weight and the requirement for axle load and wheel load balance can be accurately met without making changes to the locomotive body, and modular design and manufacture of locomotives and engineering trucks are more convenient.

Description

technical field [0001] The invention relates to locomotive axle load conversion, curb weight and balance counterweight adjustment, in particular to a locomotive counterweight and a method for adjusting the weight and center of gravity of the locomotive by using the locomotive counterweight for switching between different axle loads. Background technique [0002] The conversion between locomotives of the same type of railway with different axle loads (such as locomotives with an axle load of 23 tons and axle loads of 25 tons, locomotives with an axle load of 27 tons and locomotives with an axle load of 30 tons) is realized by counterweights, and each counterweight The weight is fixed and cannot be adjusted. However, the weight of the locomotive must meet the requirements of the curb weight of the locomotive. The deviation of the curb weight generally cannot exceed ±2% of the theoretical weight. The difference between the actual axle load of the root axle and the actual avera...
