In addition, the terms "first" and "second" are only used to distinguish in description, and have no special meaning.

[0054] As shown in the present embodiment, the installation feasibility evaluation method of the car coupler additional equipment includes the following steps: Figure 1

[0055] S10: Adjust the installation scheme of the additional equipment on the coupler.

[0056] First, the additional equipment is pre-installed at any position of the coupler hook head, or according to the experience of the staff, the additional equipment is installed at the specified position on the coupler hook head, and then the position of the additional equipment is adjusted according to the following evaluation method.

[0057] S20: Check the installation scheme of the additional equipment under the static working condition of the coupler.

[0058] Specifically, S20 includes steps S201-S202.

[0059] S201: Whether the additional equipment interferes with the movable parts of the coupler.

[0060] S202: Whether the additional equipment interferes with the car end parts.

[0061] If the additional equipment does not interfere with the movable parts of the coupler, and the additional equipment does not interfere with the car end parts, the installation scheme of the additional equipment under the static working condition of the coupler is ended, that is, the checking and evaluation of the installation scheme is continued; if the additional equipment interferes with the movable parts of the coupler, or the additional equipment interferes with the car end parts, return to S10 to move and fine-tune the installation position of the additional equipment on the coupler hook head, and repeat the above step S20 until the additional equipment does not interfere with the movable parts of the coupler, and the additional equipment does not interfere with the car end parts, then step S30 is executed.

[0062] S30: Meet the maintenance requirements of the coupler.

[0063] ​The additional equipment can be temporarily removed as needed after installation, leaving only a non-removable mounting pad after removal, which is used to mount the additional equipment on the carrier of the coupler. The mounting pad cannot block the flaw detection inspection area of the coupler, and does not affect the work of the handheld flaw detection equipment, so as to meet the coupler maintenance requirements. If the coupler maintenance requirements are not met, return to S10, move and fine-tune the installation position of the additional equipment on the coupler hook head, and repeat the above steps S20-S30 until the additional equipment does not interfere with the movable parts of the coupler and the additional equipment does not interfere with the car end parts, and meets the coupler maintenance requirements, then execute S40.

[0064] S40: Evaluation of the installation scheme of the additional equipment under static working conditions after the coupler is coupled, specifically including:

[0065] Whether the coupler coupling requirements under the highest horizontal height difference standard are met.

[0066] Specifically, the standard requirement for the highest horizontal height difference of the coupler is 75mm. If the coupler coupling requirements under the highest horizontal height difference standard are met, and the mounting pad support height of the additional equipment is greater than 95mm, it is determined that there is no influence on the multiple states of the coupler and its transformation, and the next step S50 is continued. If the coupler coupling requirements under the highest horizontal height difference standard are not met, and the mounting pad support height of the additional equipment is less than 95mm, return to S10.

[0067] S50: No influence on the multiple states of the coupler and its transformation.

[0068] The multiple states of the coupler include three states of full opening, unlocking and locking, and the additional equipment has no influence on the three states of the coupler and its transformation, which meets the requirements, and then executes S60. If the additional equipment has influence on the three states of the coupler and its transformation, return to S10.

[0069] S60: Evaluation of the installation scheme of the additional equipment under dynamic working conditions after the coupler is coupled, and the additional equipment has no interference with the car end parts and no influence on the multiple states of the coupler and its transformation.

[0070] Among them, the dynamic working conditions after the coupler is coupled include: train traction or braking, coupler travel change working condition; train passing curve, horizontal rotation of coupler and relative rotation between adjacent couplers; train uphill and downhill, vertical rotation of coupler under non-horizontal motion posture.

[0071] Under the stroke change of the coupler during train traction or braking, the additional equipment has no interference with the car end part and has no influence on the various states of the coupler and the conversion thereof; or under the maximum angle condition of the horizontal rotation of the coupler and the relative rotation between adjacent couplers when the train passes through a curve, the additional equipment has no interference with the car end part and has no influence on the various states of the coupler and the conversion thereof; or under the vertical movement posture of the coupler when the train goes uphill or downhill, the additional equipment has no interference with the car end part and has no influence on the various states of the coupler and the conversion thereof, if the additional equipment is installed for a single coupler, S80 is executed, and if the additional equipment is installed for both front and rear couplers, S70 is executed.

[0072] S70: checking the installation scheme of the additional equipment under the condition that the additional equipment is installed for both adjacent couplers.

[0073] The condition that the additional equipment is installed for both adjacent couplers includes: the static condition of the additional equipment; the relative rotation condition of the coupler and the adjacent coupler when the train passes through a curve; and the vertical rotation condition of the coupler under the non-horizontal movement posture when the train goes uphill or downhill.

[0074] If there is no interference between the additional equipment of the adjacent couplers, and there is no interference under the highest horizontal height difference standard, the requirement is met, and S80 is executed.

[0075] If there is interference between the additional equipment of the adjacent couplers, or there is interference under the highest horizontal height difference standard, S10 is returned.

[0076] S80: determining the installation scheme of the additional equipment on the coupler.

[0077] Through the execution of the steps of the installation feasibility evaluation method of the coupler additional equipment, the installation scheme of the additional equipment on the coupler hook head is finally determined, the installation conditions of the additional equipment are met, and the additional equipment that meets the evaluation requirements can meet the requirements of the complex working conditions and various states of the coupler.

[0078] The installation feasibility evaluation method of the coupler additional equipment provided in the embodiment adjusts the installation scheme of the additional equipment on the coupler hook head, checks the installation scheme of the additional equipment under the static condition of the coupler, meets the maintenance requirements of the coupler, evaluates the installation scheme of the additional equipment under the static condition after the coupler is coupled, has no influence on the various states of the coupler and the conversion thereof, evaluates the installation scheme of the additional equipment under the dynamic condition after the coupler is coupled, the additional equipment has no interference with the car end part and has no influence on the various states of the coupler and the conversion thereof, and determines the installation scheme of the additional equipment on the coupler hook head. The additional equipment meets the installation conditions, and the additional equipment that meets the evaluation requirements can meet the requirements of the complex working conditions and various states of the coupler.
