Description

Technical Field

[0001] This utility model relates to the field of soot blowers, specifically to a drag chain traveling frame for a variable-track soot blower. Background Technology

[0002] Currently, when the sootblower travel is greater than 17 meters, in order to make the sootblower nozzle's forward trajectory in the boiler approximately a straight line, the trolley's running trajectory is a complex broken line. However, the cable chain groove inside the sootblower is a straight line, which causes the trolley and cable chain to not move in parallel. There is a lack of a sootblower cable chain traveling frame that can change track. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a drag chain traveling frame for a variable track soot blower.

[0004] This utility model includes a walking frame, a push-pull rod, a tension spring, and a sports car connecting frame. A set of drag chain rollers is installed on the traveling frame. One end of the push-pull rod is movably installed on the traveling frame, and the other end of the push-pull rod is movably installed on the carriage connecting frame. A spring mounting plate is installed on the push-pull rod. One end of the tension spring is installed on the spring mounting plate, and the other end of the tension spring is installed on the top of the carriage connecting frame.

[0005] The traveling frame has a set of shaft holes, and the roller shaft of the drag chain roller is installed in the shaft holes. The end of the roller shaft has a through pin hole, and a cotter pin is inserted into the through pin hole.

[0006] The upper part of the spring mounting plate and the sports car connecting bracket are respectively provided with hanging holes. Hooks are provided at both ends of the tension spring. One end of the tension spring is hung in the hanging hole of the spring mounting plate through the hook, and the other end of the tension spring is hung in the hanging hole of the sports car connecting bracket through the hook.

[0007] The sports car connecting bracket is an L-shaped connecting bracket. A pair of connecting plates are provided on the top of the sports car connecting bracket. The connecting plates have pin holes. The push-pull rod is movably installed between the pair of connecting plates through the pin shaft.

[0008] The end of the walking frame is connected to the soot blower cable chain.

[0009] The walking frame, push-pull rod, and trolley connecting frame are all made of stainless steel.

[0010] The advantage of this invention is that it ensures that the cable chain always runs parallel within the cable chain groove when the soot blower trolley changes track. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] As shown in the attached diagram, this utility model includes a walking frame 1, a push-pull rod 2, a tension spring 3, and a trolley connecting frame 4. A set of drag chain rollers 5 are provided on the walking frame 1. One end of the push-pull rod 2 is movably installed on the walking frame 1, and the other end of the push-pull rod 2 is movably installed on the carriage connecting frame 4. A spring mounting plate 6 is provided on the push-pull rod 2. One end of the tension spring 3 is installed on the spring mounting plate 6, and the other end of the tension spring 3 is installed on the top of the carriage connecting frame 4.

[0020] The traveling frame 1 has a set of shaft holes, and the roller shaft of the drag chain roller 5 is installed in the shaft holes. The end of the roller shaft has a through pin hole, and a cotter pin is inserted into the through pin hole. The cotter pin limits the roller shaft and prevents it from falling off.

[0021] The upper parts of the spring mounting plate 6 and the sports car connecting bracket 4 are respectively provided with hanging holes. Hooks are provided at both ends of the tension spring 3. One end of the tension spring 3 is hung in the hanging hole of the spring mounting plate 6 via a hook, and the other end of the tension spring 3 is hung in the hanging hole of the sports car connecting bracket 4 via a hook. The tension spring 3 uses a hook connection method, making disassembly and installation convenient.

[0022] The sports car connecting bracket 4 is an L-shaped connecting bracket. A pair of connecting plates 7 are provided on the top of the sports car connecting bracket 4. The connecting plates 7 have pin holes. The push-pull rod 2 is movably installed between the pair of connecting plates 7 through the pin shaft.

[0023] The end of the walking frame 1 is connected to the soot blower cable chain 100.

[0024] The walking frame 1, push-pull rod 2, and trolley connecting frame 4 are all made of stainless steel.

[0025] Example 1: The trolley connecting frame 4 is installed on the sootblower trolley, and the end of the traveling frame 1 is connected to the sootblower cable chain 100. One end of the cable inside the sootblower cable chain 100 is connected to the trolley motor, and the other end is connected to the control box of the sootblower. The cable chain groove inside the sootblower is installed horizontally.

[0026] As attached Figure 3 As shown, when the sootblower trolley moves forward and changes track, it descends. Under the elastic force of the tension spring 3, it pulls up the push-pull rod 2, which in turn pulls the traveling frame 1 upward, causing a set of drag chain rollers 5 to roll against the upper part of the sootblower beam, ensuring that the sootblower drag chain 100 always moves within the drag chain groove. When the sootblower trolley moves backward and changes track, it rises, and the push-pull rod 2 returns to its original position.
