Description

Technical Field

[0001] The utility model relates to the field of port equipment, in particular to the field of tooling used for quenching track running wheels. Background Art

[0002] The bottom layer of the port equipment walking mechanism is equipped with a track running wheel component, which bears the entire weight of the port equipment. The inside of the running wheel component needs to have good toughness, and the external tread needs to have good rigidity, hardness and wear resistance to meet the operational requirements of the port terminal. In order to achieve the above goals, the tread part of the running wheel component needs to be heat treated.

[0003] During the heat treatment process, the traveling wheel is first placed in a heating furnace and heated to above the critical temperature. After being kept warm for a period of time, the traveling wheel tread is quickly heat-treated and quenched. The quenching process requires that only the material structure of the traveling wheel tread can be quickly cooled, so the traditional operation method is cumbersome and inconvenient. Therefore, it is necessary to provide a tooling to efficiently complete the heat treatment process while ensuring that when the traveling wheel is immersed in the quenching pool, the quenching liquid only contacts the material structure of the traveling wheel tread and the inside of the traveling wheel does not participate in the heat treatment quenching operation. Utility Model Content

[0004] One purpose of the utility model is to provide a tool for quenching the tread of a track running wheel, so as to conveniently and efficiently realize the tread quenching operation of the running wheel.

[0006] In one or more embodiments, an open groove is formed at the upper end of the support hanger, and the clamping block is located in the open groove and is rotatably connected to the support hanger via a pin shaft.

[0007] In one or more embodiments, the tool further comprises a shackle disposed at the second end.

[0008] In one or more embodiments, the lifting portion includes a sling, and the sling is detachably connected to the pressing block via the shackle.

[0009] In one or more embodiments, the chassis includes a supporting portion and a protruding portion, wherein the supporting portion is used to carry the track running wheel, and the protruding portion is used to install the supporting boom.

[0025] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0026] It should be noted that these and other subsequent drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual scope of protection required by the present utility model.

[0027] Reference Figures 1 to 3 As shown, the tooling for quenching the track running wheel includes a chassis 11, a support hanger 12, a sealing plate 13, a clamping block 14 and a hoisting part 15. The chassis 11 is used to support the bottom of the track running wheel 5, the support hanger is arranged on the chassis, the sealing plate is used to cover the upper part of the track running wheel, the clamping block 14 is rotatably arranged on the upper end of the support hanger, including a first end and a second end, the first end is used to clamp the sealing plate, and the hoisting part 15 is arranged at the second end of the clamping block, so that the clamping block 14 can use the lever action to make the first end clamp the sealing plate 13 on the track running wheel 5 during hoisting, so as to ensure the sealing between the sealing plate 13, the running wheel 5 and the chassis 11.

[0028] Specifically, the chassis 11 includes a supporting portion 111 and a protruding portion 112. The supporting portion 111 is used to carry the track running wheel, and the protruding portion 112 is used to install the support hanger 12. The supporting portion 111 also includes a first arc-shaped groove 113, which forms a step plane, which is used to abut against the lower peripheral flange 52 and the lower plane of the track running wheel 5. A liquid leakage port 114 is also provided on the chassis component to ensure that when the entire quenching tool is lifted out of the quenching liquid pool, liquid accumulation is prevented at the gap step, and excess quenching liquid can be drained out. The chassis is equipped with a plurality of clamping shaft plates 116, which are fastened to the chassis 11 by bolts and gaskets, and cooperate with the clamping plate grooves 129 on the support hanger 12, such as Figure 4A and Figure 5A As shown, the support boom 12 is prevented from falling downward.

[0029] The upper end of the support rod 12 is provided with an open slot 120, and the pressing block 14 is located in the open slot 120 and is rotatably connected to the support rod via a connecting shaft. Figure 5A-5BAs shown, a pin hole 121 and an open slot 120 are respectively provided at the upper end of the support boom 12, which cooperate with the pin 17 and the clamping block 14 respectively. The clamping block 14 is fixed in the open slot 120, and the clamping block 14 is rotated around the center of the pin during lifting. A step is provided at one end of the pin 17, and a small pin hole is provided at the other end, which cooperates with the open pin 170 to prevent the pin from moving. The first end 147 of the clamping block 14 is designed as an "eagle hook" shaped claw to maximize the clamping range. The second end 148 of the clamping block 14 is provided with a shackle 19 and a shackle bolt 190, which are detachably connected to the sling 151, so as to facilitate the connection with the shackle of the lifting part. A protruding step 124 is also provided at the bottom of the support boom 12, which engages with the recessed step 115 on the chassis, as shown in FIG. Figure 3 As shown, the two can move together during the lifting process.

[0030] Continue to refer to Figure 3 As shown, the purpose of the sealing plate 13 is to cover the upper plane of the running wheel 5, so that the chassis 11, the running wheel 5 and the cover plate 13 form a closed space G. A threaded hole is provided at the center of the upper plane of the sealing plate 13, which matches the eye screw 131 to facilitate the lifting of the sealing plate 13. The sealing plate 13 is provided with a second arc-shaped groove 133, forming a stepped plane, which fits with the upper plane of the running wheel and the upper peripheral flange to form a closed space together.

[0031] The main function of the hoisting part 15 is to connect the hoisting running wheel quenching tooling to achieve overall hoisting, which specifically includes a shackle, a butterfly buckle, a sling 151 and a hanging plate 152. The hanging plate 152 is symmetrically arranged with two pin holes that match the shackle of the sling 151 to ensure a smooth lifting process. The hoisting part 15 is connected to the second end of the clamping block 14 through the sling 151, and an upward hoisting force is applied to the second end.

[0032] In this way, the clamping block 14 cooperates with the lifting part with the help of the lever to form a deadweight clamping structure, so that the tooling can use its own weight and the weight of the supported running wheel to provide a force to press down the sealing plate 13. The greater the deadweight, the greater the downward force, and then clamp the sealing plate 13 and the chassis 11 to fully fit the upper and lower surfaces of the running wheel 5. Under the pressure of the clamping block 14, the upper and lower contact surfaces of the sealing plate 13 and the chassis 11 and the running wheel 5 are sealed, so that the upper and lower fitting surfaces A and fitting surface B are formed between the quenching tooling and the running wheel, and a closed space is formed in the middle to meet the operation requirements of the running wheel immersion quenching.

[0033] The track wheel tread quenching tool can perform tread quenching operations on the track wheels within a certain thickness and diameter range. The following is a detailed introduction to the use of the tool.

[0034] When the heat treatment workshop needs to quench the track wheel tread, the wheel 5 is first hoisted into the heating furnace for heating for several hours. The tooling is hoisted to the designated position between the quenching pool and the heating furnace.

[0035] Lift the cover plate 13 on the running wheel and put it aside for use. Push out the shackle screw of the lifting part and rotate the clamping block 14 of the deadweight clamping part to make the first end 147 tilt upward in the direction P to allow the running wheel 5 to be placed in the chassis 11. Clean the flat steps on the chassis components to make sure there is no debris on the fitting surface, such as Fig. 8A shown.

[0036] When the running wheel 5 is heated to the specified time and temperature, the running wheel 5 is hoisted onto the chassis 11 of the tread quenching tooling by a hoisting device, so that the lower plane of the running wheel 5 is in contact with the supporting plane of the chassis component, as shown in FIG. Figure 8B shown.

[0037] The cover plate 13 is then lifted to the top of the running wheel 5 by a lifting device. The pressing block 14 is rotated in the direction P′ so that the first end 147 is pressed on the sealing plate 13.

[0038] Quickly hang the lifting part on the lifting hook to connect the lifting part, the sling and the clamping block 14. When the lifting equipment hook is lifted upward, one end of the clamping block 14 is pulled upward, and the other end presses down the sealing plate 13 with the help of a lever, so that the two sets of contacting planes of the sealing plate 13, the running wheel 5 and the chassis 11 fit tightly together to form a closed space. Figure 8C-8D At this point, the tread of the travel wheel is exposed on the outside, and the quenching part does not need to be completely sealed on the inside.

[0039] Finally, operate the lifting equipment to immerse the rail running wheel tread quenching tooling and the running wheel into the quenching liquid pool as a whole to complete the heat treatment quenching process.

[0040] The above-mentioned tooling utilizes the quenching tooling and the weight of the traveling wheel to set up a deadweight clamping mechanism, so as to achieve the purpose of close fit between the planes on both sides of the traveling wheel and the contact planes between the chassis components and the cover components, thereby ensuring the internal sealing. At the same time, the device can conveniently, quickly, safely and reliably perform heat treatment quenching operations on the treads of the traveling wheels, solving the thorny problem of immersion quenching of the track traveling wheels. The tooling makes the heat treatment process of the traveling wheels convenient, fast, safe and reliable.
