Description

Technical Field

[0001] The utility model relates to the field of track shoe manufacturing, in particular to the technical field of track shoe quenching, and specifically refers to a surge device for track shoe quenching. Background Art

[0002] Track shoes are one of the chassis components of construction machinery and are a consumable part of the machinery used. They are commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Common track shoes are categorized by their contact surface configuration: single-ribbed, triple-ribbed, and flat-bottomed. Some also feature triangular track shoes. Single-ribbed track shoes are primarily used on bulldozers and tractors, as these machines require high traction. However, they are rarely used on excavators, being used only when equipped with a drill rig or requiring high horizontal thrust. Because high traction is required when turning, taller ribs (spurs) can displace soil (or ground) between the ribs, affecting the excavator's maneuverability.

[0003] Track shoes need to be quenched during the manufacturing process. In the current process, the quenching liquid is stationary. When the high-temperature workpiece is placed in the quenching tank, the temperature of the quenching medium around the workpiece will rise sharply. The heat of the quenching medium around the workpiece cannot be dissipated quickly, and the cooling rate is reduced. This leads to uneven cooling of the track shoe and poor hardenability, thus affecting the quality of the track shoe. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a surge device for quenching track shoes, which uses quenching liquid to drive the quenching liquid in the quenching pool to surge. The quenching liquid surges back and forth to form stirring, thereby accelerating the cooling zone rate, facilitating uniform cooling, and at the same time improving the hardenability of the track shoe to ensure the quality of the track shoe.

[0005] The utility model is realized by the following technical solution: a surge device for quenching a track shoe, comprising a pipe rack located in a quenching pool, the pipe rack comprising a plurality of spray branches arranged along the circumferential direction, and a spray main pipe for supplying liquid to the spray branches, wherein the spray branches are provided with a spray port for driving the surge of quenching liquid.

[0006] When the utility model is in use, the quenching liquid is introduced into the liquid spray branch pipe through the liquid spray main pipe and sprayed out from the liquid spray port, so that the quenching liquid drives the quenching liquid to surge in the quenching tank. The quenching liquid is blocked by the inner wall of the quenching tank, so that the quenching liquid surges back and forth to form a stirring, thereby accelerating the cooling zone rate, facilitating uniform cooling, and at the same time improving the hardenability of the crawler shoe and ensuring the quality of the crawler shoe. When the present solution is in use, the crawler shoe is placed inside the circular or square formed by the plurality of liquid spray branch pipes, so that the quenching liquid drives the quenching liquid to surge in the crawler shoe immediately.

[0007] Preferably, the plurality of liquid spray main pipes are interconnected, valves are provided on both openings of the liquid spray branch pipes, and at least one liquid spray main pipe is connected to a liquid inlet pipe.

[0008] In this preferred solution, by interconnecting the liquid spraying main pipes, one liquid inlet pipe is provided to meet the supply of quenching liquid. At the same time, the flow path of the quenching liquid is easily controlled by the arrangement of valves.

[0009] Preferably, the pipe rack includes a plurality of auxiliary units, each of which includes two liquid spraying main pipes arranged in the height direction and a plurality of liquid spraying branch pipes connecting the two liquid spraying main pipes, and the liquid spraying main pipes corresponding to two adjacent auxiliary units are connected via a joint.

[0010] When this preferred solution is in use, the auxiliary units are provided to modularize the pipe rack, thereby facilitating the assembly and processing of the pipe rack.

[0011] Preferably, two liquid inlet pipes are provided, one liquid inlet pipe is connected to a liquid spray main pipe located at the upper end of the liquid spray branch pipe, and the other liquid inlet pipe is connected to a liquid spray main pipe located at the lower end of the liquid spray branch pipe.

[0012] This preferred solution ensures that there is sufficient quenching liquid in the liquid spray branch pipe by providing two liquid inlet pipes.

[0013] Preferably, a plurality of the liquid spraying main pipes located at the same height form a square.

[0014] This preferred solution increases the placement space of the crawler plate by enclosing the square arrangement, and the square arrangement also facilitates splicing and forming through pipes and joints.

[0015] Preferably, the liquid spraying branch pipe is provided with a liquid spraying port for spraying liquid toward the track shoe. This preferred solution facilitates the quenching liquid to blow the quenching liquid in the pipe rack through the location of the liquid spraying port, so that the quenching liquid at the track shoe surges immediately.

[0016] Preferably, a plurality of liquid spray ports form a first liquid spray surface, a second liquid spray surface, a third liquid spray surface and a fourth liquid spray surface which are arranged in sequence along the circumference of the track shoe. The first liquid spray surface and the third liquid spray surface are arranged opposite to each other and are arranged in the transverse direction, the second liquid spray surface and the fourth liquid spray surface are arranged opposite to each other and are arranged in the longitudinal direction, the liquid spray holes on the first liquid spray surface and the third liquid spray surface extend in the transverse direction, and the liquid spray holes on the second liquid spray surface and the fourth liquid spray surface extend in the longitudinal direction.

[0017] This preferred solution has multiple usage methods when in use. Through valve control, the quenching liquid can be sprayed out from at least one spray surface. There are also multiple ways to arrange and combine the four spray surfaces, so there are also multiple options for the flow direction and method of the quenching liquid.

[0018] The beneficial effects of the present invention are as follows: the quenching liquid is introduced into the liquid spray branch pipe through the liquid spray main pipe and sprayed out from the liquid spray port, so that the quenching liquid pushes the quenching liquid to surge in the quenching pool. The quenching liquid is blocked by the inner wall of the quenching pool, so that the quenching liquid surges back and forth to form stirring, thereby accelerating the cooling zone rate, improving the hardenability of the track shoe, and ensuring the quality of the track shoe. When the present solution is in use, the track shoe is placed inside the circle or square formed by the plurality of liquid spray branch pipes, so that the quenching liquid drives the quenching liquid to surge at the track shoe at the first time; by setting the liquid spray main pipes to be connected to each other, a liquid inlet pipe can be provided to meet the supply of quenching liquid, and at the same time, the valve setting facilitates the control of the flow path of the quenching liquid; by setting the position of the liquid spray port, it is convenient for the quenching liquid to blow the quenching liquid in the pipe rack, so that the quenching liquid at the track shoe surges at the first time.

[0026] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0027] Refer to the attached Figure 1-5 The utility model provides a surge device for quenching a track shoe, comprising a pipe rack located in a quenching pool, the pipe rack comprising four side frames connected end to end in a circumferential direction, the four side frames forming a regular hexahedron space, the side frame comprising two auxiliary units, the auxiliary units comprising two liquid spraying main pipes 1 arranged in a height direction and extending horizontally, and a plurality of two liquid spraying branch pipes 2 connecting the two liquid spraying main pipes 1, the liquid spraying branch pipes 2 being located between the two liquid spraying main pipes 1, and the two liquid spraying main pipes 1 at the same height of two adjacent auxiliary units being connected via a joint 3.

[0028] The two liquid spraying main pipes 1 at corresponding positions on two adjacent side frames are also connected by a joint 3. In a top view, the eight liquid spraying main pipes 1 at the same height form a square.

[0029] The liquid spraying main pipes 1 located at the same height are connected to each other, and valves are provided on the two openings of the liquid spraying branch pipe 2. The quenching liquid is connected with two liquid inlet pipes 4, one liquid inlet pipe 4 is connected to a liquid spraying main pipe 1 located at the upper end of the liquid spraying branch pipe 2, and the other liquid inlet pipe 4 is connected to a liquid spraying main pipe 1 located at the lower end of the liquid spraying branch pipe 2. A liquid inlet pump is provided on both liquid inlet pipes, and the liquid inlet of the liquid inlet pump is connected to the quenching tank. The liquid inlet pump pumps the quenching liquid into the liquid inlet pipe.

[0030] The liquid spraying branch pipe 2 is provided with liquid spraying ports for spraying liquid toward the track shoe. That is, relative to the regular hexahedron space, all the liquid spraying ports spray liquid toward the inside of the hexahedron. The liquid spraying pipe extends in the height direction, and several liquid spraying ports are arranged in the height direction.

[0031] The four side frames correspond to four liquid spraying surfaces, which are respectively a first liquid spraying surface, a second liquid spraying surface, a third liquid spraying surface, and a fourth liquid spraying surface. The first liquid spraying surface and the third liquid spraying surface are arranged opposite to each other and are arranged in the horizontal direction, and the second liquid spraying surface and the fourth liquid spraying surface are arranged opposite to each other and are arranged in the vertical direction. The liquid spraying holes located on the first liquid spraying surface and the third liquid spraying surface extend in the horizontal direction, and the liquid spraying holes located on the second liquid spraying surface and the fourth liquid spraying surface extend in the vertical direction.

[0032] When the utility model is in use, the quenching liquid is introduced into the liquid spray branch pipe 2 through the liquid spray main pipe 1 and sprayed out from the liquid spray port, so that the quenching liquid pushes the quenching liquid to surge in the quenching pool. The quenching liquid is blocked by the inner wall of the quenching pool, so that the quenching liquid surges back and forth to form stirring, thereby accelerating the cooling zone rate, improving the hardenability of the track shoe, and ensuring the quality of the track shoe. When the present solution is in use, the track shoe is placed on the inner side of the circle or square formed by the plurality of liquid spray branch pipes 2, so that the quenching liquid drives the quenching liquid to surge at the track shoe at the first time; by setting the liquid spray main pipes 1 to be interconnected, providing a liquid inlet pipe 4 can meet the supply of quenching liquid, and by setting the valve, it is convenient to control the flow path of the quenching liquid; by setting the position of the liquid spray port, it is convenient to make the quenching liquid blow the quenching liquid in the pipe rack, so that the quenching liquid at the track shoe surges at the first time.

[0033] The four spray surfaces can be selected to spray liquid according to actual conditions. For example, the four spray surfaces can be made to spray liquid separately, or the first spray surface and the second spray surface can be made to spray liquid in coordination, the first spray surface and the third spray surface can be made to spray liquid in coordination, the first spray surface, the second spray surface and the third spray surface can be made to spray liquid in coordination, the fourth spray surface and the second spray surface can be made to spray liquid in coordination, the fourth spray surface and the third spray surface can be made to spray liquid in coordination, and the fourth spray surface, the second spray surface and the third spray surface can be made to spray liquid in coordination.

[0034] Regardless of the above-mentioned liquid spraying method, after the quenching liquid flows, it is blocked when it hits the inner wall of the quenching pool, so that the quenching liquid surges back and forth in the quenching pool, thereby achieving stirring of the quenching liquid in the quenching pool, thereby accelerating the cooling zone rate and improving the hardenability of the track shoe.
