Description

Technical Field

[0001] The utility model relates to the field of normalizing pickling units for non-oriented silicon steel production lines, and more specifically, to a quick removal tool for the pin shaft of a loop wheel. Background Art

[0002] When replacing the wheels of the loop carriage of the normalizing pickling unit, the normalizing pickling unit is mainly used for surface cleaning and removal of the oxide layer of hot-rolled steel coils to improve the surface quality and corrosion resistance of the steel. The key process equipment of the normalizing pickling unit includes welding machines, normalizing furnaces, pickling sections, etc. The selection of these equipment has a direct impact on the performance and production efficiency of the entire unit. Among them, the wheels of the loop carriage need to be replaced frequently. Currently, when replacing the vehicle, the pin shaft is first removed to facilitate wheel replacement. The existing method for removing the pin shaft is that the operator first climbs to a ladder as high as 3m to perform the operation. This is because of the design of the carriage, and personnel cannot enter the inner side to strike the pin shaft, resulting in the inability to remove it. When working at a height, there is first a risk of falling from a height, and then multiple people are required for the operation. For example, at least 2 people are needed to hold the ladder, resulting in an operation time of at least 40 minutes, increasing the working intensity of the operator. Content of the Utility Model

[0003] To solve the above problems, the utility model adopts the following technical solutions.

[0004] The utility model discloses a quick removal tool for the pin shaft of a loop wheel, including a stop block, a conduit, a counterweight, and a connecting device. The counterweight is sleeved on the conduit, the stop block is installed at one end of the conduit, and one end of the connecting device is connected to the other end of the conduit, and the connecting device is connected to one end of the pin shaft of the loop wheel.

[0005] Further, the connecting device is a screw rod. The screw rod is provided with an external thread, and the pin shaft is provided with an internal thread. One end of the screw rod is threadedly connected to the pin shaft.

[0006] Further, the conduit is a steel pipe. The diameter of the screw rod is smaller than the diameter of the conduit. The front end of the conduit is provided with a frustum portion, and the conduit is welded to the screw rod through the frustum portion.

[0007] Further, the stop block is a square iron block, and one end of the conduit is welded to the center of the square iron block.

[0008] Further, the counterweight is a cylinder.

[0009] Further, the length of the conduit is 50 cm, the nominal diameter is 40 mm, the screw rod model is M22, and the side length of the stop block is 10 cm.

[0010] Advantageous Effects

[0011] Compared with the prior art, the advantages of the utility model are as follows:

[0012] The operator only needs to stand on the platform to easily take out the pin shaft. During the operation, the inertial principle of the sliding counterweight is fully utilized, thus significantly saving time and labor costs, effectively avoiding the risks of edge fall and object strike, and also significantly improving work efficiency, achieving the purpose of reducing risks and improving efficiency. Brief Description of the Drawings

[0015] Figure 3 It is a schematic diagram of a conduit of an embodiment of the present invention. Detailed Embodiment

[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] As shown in the figure, the present invention discloses a quick removal tool for the pin shaft of a loose pulley wheel, which includes a stop block 1, a conduit 2, a counterweight block 3 and a connecting device 4. The counterweight block 3 is sleeved on the conduit 2, the stop block 1 is installed at one end of the conduit 2, one end of the connecting device 4 is connected to the other end of the conduit 2, and the connecting device 4 is connected to one end of the loose pulley wheel pin shaft 5. When in use, the connecting device 4 is connected to the pin shaft 5, and then the counterweight block 3 is used. The counterweight block 3 slides on the conduit 2 and impacts the stop block 1. The stop block 1 transmits the force to the connecting device 4, and then transmits the force to the pin shaft 5. By using the counterweight block 3 to impact the stop block 1 multiple times, the pin shaft 5 is finally taken out.

[0018] In an embodiment of the present invention, the connecting device 4 is a screw. The screw is provided with an external thread, and the pin shaft 5 is provided with an internal thread, or a nut is welded to the front end of the pin shaft 5. One end of the screw is threadedly connected to the pin shaft 5. The setting of the screw makes it convenient for the screw to be connected to the pin shaft 5.

[0019] In an embodiment of the present invention, the conduit 2 is a steel pipe. The diameter of the screw is smaller than the diameter of the conduit 2. The front end of the conduit 2 is provided with a frustum portion 21. The conduit 2 is welded to the screw through the frustum portion 21. During manufacturing, the end of the cylindrical steel pipe can be first cut into a serrated shape and then knocked to form the frustum portion 21. Cutting into a serrated shape is to leave space for the front end to deform.

[0020] In an embodiment of the present invention, the stop block 1 is a square iron block. One end of the conduit 2 is welded to the center of the square iron block. The stop block 1 serves to block the counterweight block 3 and transmit the force to the pin shaft 5.

[0021] In one embodiment of the present invention, the counterweight 3 is a cylinder.

[0022] In an embodiment of the present invention, the length of the conduit 2 is 50 cm, the nominal diameter is 40 mm, the screw model is M22, and the side length of the stopper is 10 cm.

[0023] The utility model successfully realizes the connection between the pin and the external object by using the threaded hole or welding nut of the pin, thereby realizing the disguised extension of the pin. This measure greatly improves the convenience of operation, so that the personnel using this tool can easily take out the pin by just standing on the platform. During the operation, the inertia principle of the sliding counterweight is fully utilized, thereby significantly saving time and labor costs.

[0024] Compared with the traditional method of using ladders, hand hammers and steel pipes to remove the pins, the utility model has significant advantages. The traditional method not only requires the operator to be at the edge, but also requires a special person to hold the ladder, which is not only time-consuming and labor-intensive, but also poses a great safety risk. At least three people are needed to complete this operation. The utility model only takes 3-5 minutes to complete the removal of the pin, and only one person is required to operate it. This improvement not only effectively avoids the risk of falling from the edge and the risk of being hit by objects, but also significantly improves work efficiency, achieving the purpose of reducing risks and improving efficiency.

[0025] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
