The tooling includes a first frame and a second frame. The first frame and the second frame have the same structure. A plurality of pedals 1 are arranged between the first frame and the second frame. The pedals 1 serve as a stepping platform for maintenance personnel during maintenance. An upper card plate 2 and a lower card plate 3 are arranged at the bottom of the first frame and the second frame. A card slot is formed between the upper card plate 2 and the lower card plate 3. A platform 15 on one side of the high-speed train can extend into the card slot. A locking member is arranged on the upper card plate. The locking member can lock and fix the upper card plate 2, the lower card plate 3 and the platform 15, thereby achieving the fixation of the entire tooling to the platform 15 on one side of the train. The first frame and the second frame are also provided with a telescopic component. The end of the telescopic part of the telescopic component is universally connected with a suction cup 4. The telescopic part of the telescopic component can be extended so that the suction cup 4 is adsorbed and fixed to the surface of the train head, thereby achieving the firm fixation of the entire tooling.

[0028] The structures of the first frame and the second frame are the same, and the first frame is used as an example for explanation:

[0029] The first frame includes a vertical rod 5. In this embodiment, the vertical rod 5 is made of round steel or square steel. The first frame also includes a diagonal support rod 6. The diagonal support rod 6 is made of round steel or square steel. The bottom end of the diagonal support rod 6 is welded and fixed to one side of the vertical rod. The diagonal support rod 6 and the vertical rod 5 are set at a set acute angle. The degree of the set acute angle can be set according to actual needs and will not be described in detail here.

[0030] An upper clamping plate 2 and a lower clamping plate 3 are disposed on the other side of the bottom end of the vertical rod 5 , and the upper clamping plate 2 and the lower clamping plate 3 are vertically welded and fixed to the vertical rod 5 .

[0031] The distance between the upper pallet 2 and the lower pallet 3 is greater than the thickness of the platform on one side of the train, so that the upper pallet 2 and the lower pallet 3 can be placed above and below the side of the platform respectively.

[0032] The upper clamping plate 2 is provided with a locking member, which is used to lock and fix the upper clamping plate 2, the lower clamping plate 3 and the platform.

[0033] In this embodiment, the locking member adopts a locking bolt 7. For the convenience of operation, the upper clamping plate 2 is threadedly connected with the locking bolt 7. The locking bolt 7 is vertically arranged to the upper clamping plate 2. By rotating the locking bolt 7, the locking bolt 7 can move along its own axial direction. The locking bolt 6 and the lower clamping plate 3 jointly clamp and fix the platform 15, thereby realizing the locking and fixation of the upper clamping plate 2, the lower clamping plate 3 and the platform.

[0034] Furthermore, a handle is provided on the top of the locking bolt 7 to facilitate the staff to rotate the locking bolt.

[0035] A plurality of pedals 1 are provided between the two diagonal braces of the first frame and the second frame. The pedals are welded and fixed to the diagonal braces 6. The plurality of pedals 1 are distributed along the axis direction of the diagonal braces 6. The pedals 1 are arranged horizontally and serve as a stepping platform for maintenance personnel during maintenance work. The angle between the diagonal braces 6 and the vertical rods 5 and the spacing between adjacent pedals 1 conform to the ergonomic design, which is convenient for operators to climb. The design of the angle and spacing can be based on the existing technology and will not be described in detail here.

[0036] Furthermore, the upper surface of the pedal 1 is provided with anti-skid grooves to prevent the staff from slipping when stepping on it, thereby ensuring the safety of the staff.

[0037] The top ends of the vertical rods 5 and the diagonal braces 6 are provided with handrails 8, and a telescopic component is provided between the bottom end of the handrail 8 and the top ends of the vertical rods 5 and the diagonal braces 6. The fixed part of the telescopic component is fixedly connected to the top ends of the vertical rods 5 and the diagonal braces 6 and the bottom end of the handrail 8.

[0038] Furthermore, the handrail 8 adopts a U-shaped rod, including a horizontal portion and vertical portions located on both sides of the horizontal portion, the bottom ends of the two vertical portions correspond to the tops of the vertical rod 5 and the diagonal support rod 6 respectively, and the bottom ends of the vertical portions are fixedly connected to the fixed portion of the telescopic component.

[0039] Furthermore, the handrail 8, the vertical rod 5, and the diagonal brace 6 are all made of aluminum alloy, have sufficient bearing capacity and light weight, and are easy to move and install.

[0040] In one embodiment, the telescopic component adopts a mechanical telescopic rod, which includes a fixed part and a telescopic part telescopically connected to the fixed part, the end of the telescopic part is universally connected with a suction cup, the end of the fixed part is coaxially threaded with a driving rod, the end of the driving rod extending into the fixed part is rotatably connected to one end of the telescopic part through a bearing, the telescopic part is slidably connected to the fixed part, and the driving rod is rotated. The driving rod can move along its own axial direction, thereby driving the telescopic part to perform telescopic movement. Furthermore, a hand wheel is provided at the end of the driving rod to facilitate the staff to rotate the driving rod.

[0041] In another embodiment, the telescopic component includes an active telescopic rod 9 and a driven telescopic rod 10 which are arranged in parallel side by side up and down, the fixed parts of the active telescopic rod 9 and the driven telescopic rod 10 are fixedly connected, the telescopic parts of the active telescopic rod 9 and the driven telescopic rod 10 are connected by a connecting plate 11, and the end of the telescopic part of the driven telescopic rod 10 is universally connected with a suction cup 4.

[0042] In this embodiment, the active telescopic rod 9 is an electric telescopic rod or a hydraulic cylinder, preferably an electric telescopic rod, and the driven telescopic rod 10 is a mechanical telescopic rod including a fixed portion and a telescopic portion telescopically connected to the fixed portion.

[0043] With this arrangement, the telescopic portion of the active telescopic rod 9 can drive the telescopic portion of the driven telescopic rod 10 to perform telescopic movement through the connecting plate 11 , and the driven telescopic rod 10 can enhance the stability and reliability of the structure of the active telescopic rod 9 .

[0044] The suction cup 4 is made of rubber material, has high adsorption force and good wear resistance, and the suction cup 4 is universally connected to the telescopic part of the telescopic component. Specifically, the end of the telescopic part of the telescopic component is connected to one end of a connecting rod, and the other end of the connecting rod is provided with a ball head 12. A spherical groove matching the ball head 12 is provided in the middle of the suction cup 4, and the ball head 12 is embedded in the spherical groove so that the suction cup 4 is universally connected to the telescopic part of the telescopic component.

[0045] The suction cup 4 can be adjusted by the ball head 12 to meet the adsorption and fixation requirements of the suction cup and the surface of the vehicle head under the irregular shape of the vehicle head.

[0046] In this embodiment, the suction cup 4 is squeezed to discharge the air in the suction cup 4, so that the suction cup is adsorbed and fixed to the surface of the train head under the action of atmospheric pressure. In one embodiment, a pressure sensor can be installed in the suction cup 4 to detect the gas pressure in the suction cup. When the gas pressure is greater than the set value, it indicates that the vacuum degree in the suction cup is insufficient, which further indicates that the adsorption force of the suction cup is insufficient.

[0047] The pressure sensor is connected to the control system, and the control system is connected to the alarm device. When the adsorption force is insufficient, the control system controls the alarm device to sound an alarm.

[0048] In this embodiment, the control system and the alarm device are installed in the control box 13, and the control box 13 is fixed on the outer side of the diagonal support rod 6 on one side. The control system is connected to the active telescopic rod 9 and the pressure sensor. The pressure sensor can transmit the collected information to the control system, and the control system can control the operation of the active telescopic rod.

[0049] The alarm device can be an existing buzzer alarm or alarm light 14, and those skilled in the art can select one according to actual needs.

[0050] The auxiliary tooling also includes a suspension sling, which adopts an existing safety anti-slip sling made of synthetic fiber material and has excellent tensile strength. One end of the suspension sling is used to be tied and fixed to the top of the handrail 8 of the first frame or the second frame, and the other end is provided with a hook, which can be connected to the guardrail of the platform 15 on one side of the train through the hook.

[0051] By setting up a hanging sling, when the work equipment tends to fall off accidentally, it can bear the weight and prevent it from injuring the ground workers.

[0052] Example 2

[0053] This embodiment provides a working method of the high-speed train head climbing auxiliary tooling described in Embodiment 1: Figure 2 As shown, the entire tool is moved to the position to be inspected on the head 16 of the high-speed train, such as one side of the wiper, and the tool is moved. The upper clamping plate 2 is moved above the platform 15 on one side of the train, and the lower clamping plate 3 is moved below the platform 15. The locking bolt 7 is rotated so that the locking bolt 7 and the lower clamping plate 3 jointly clamp the fixed platform 15, completing the fixation of the entire tool. The telescopic parts of the two telescopic components are extended, so that the suction cup 4 contacts the outer surface of the head 14 of the high-speed train and is adsorbed and fixed.

[0054] The tooling personnel use the pedal to climb up and use the pedal 1 as a working platform for the wiper inspection to inspect the wiper. During the operation, the suspension strap is always connected to the handrail 8 at one end and the guardrail on the platform at the other end to play a safety protection role. After the inspection is completed, the telescopic part is retracted to release the suction cup, and then the locking bolt is removed and the tooling is removed for storage.

[0055] By adopting the tooling of this embodiment, maintenance personnel do not need to climb the front of the train, and the operation is more convenient and safer. Moreover, the tooling is arranged on the side of the front of the train, which meets the needs of maintenance work at any position of the front of a high-speed train and is suitable for maintenance operations on the head of a high-speed train. Moreover, it is fixed to the platform on one side of the train through the first clamping plate, the second clamping plate and the locking member, and is fixed to the surface of the high-speed train through the telescopic component and the suction cup, thereby realizing double-sided multi-point fixation, ensuring the stability of the tooling during work, and further ensuring the safety of the maintenance personnel. Moreover, the suction cup is universally connected to the telescopic part of the telescopic component, and the suction cup can adapt to the surface of the head of the high-speed train to ensure the firmness of the adsorption.

[0056] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
