Description

Technical Field

[0001] This utility model relates to a tool for quickly changing belt rollers in a blast furnace, belonging to the technical field of ironmaking equipment. Background Technology

[0002] During the replacement of belt idlers in a blast furnace, the presence of raw material on the drive belt increases its weight, making it impossible to manually pry it up with a pry bar and replace the rollers underneath. In this situation, replacing the rollers requires manually removing material from the drive belt to reduce its weight, which not only increases the time and effort required but also hinders the roller replacement progress. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a tool for quickly changing belt rollers in blast furnaces, which is easy to operate, can quickly change rollers, saves time and effort, and improves the efficiency of roller replacement.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a tool for quickly replacing belt rollers in a blast furnace. The tool is located below the transmission belt at the roller to be replaced. The tool includes two spaced-apart lifting devices. Vertical support rods are respectively provided on the two lifting devices. A tray is provided on the top of each support rod. A horizontally arranged top rod is provided between the two trays. The lifting devices synchronously drive the corresponding support rods to rise, thereby driving the trays and top rods to rise, so that the top rod lifts the transmission belt.

[0005] The tray has holes, and the two ends of the top rod are inserted into the corresponding holes.

[0006] The length of the push rod exceeds the width of the drive belt.

[0007] The lifting device is a hydraulic jack.

[0008] Compared with the prior art, the advantages of this utility model are: a tool for quickly changing belt rollers in a blast furnace is easy to operate. It uses a hydraulic jack to drive the top rod to lift the transmission belt with raw materials, which can quickly change the rollers, saving time and effort and improving the efficiency of roller replacement. Attached Figure Description

[0009] Figure 1 This is a schematic diagram illustrating the replacement of a quick belt roller replacement tool for a blast furnace according to an embodiment of the present invention;

[0010] Figure 2 This is a schematic diagram of a tool for quickly changing belt rollers in a blast furnace, according to an embodiment of the present invention.

[0011] In the diagram, 1 is a hydraulic jack, 2 is a support rod, 3 is a tray, 4 is a top rod, and 5 is a conveyor belt. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , 2 As shown in this embodiment, a tool for quickly replacing belt rollers in a blast furnace includes two spaced-apart hydraulic jacks 1. Each hydraulic jack 1 has a vertically arranged support rod 2. A tray 3 is mounted on the top of each support rod 2, and insertion holes are formed on the tray 3. A horizontally arranged push rod 4 is inserted between the two insertion holes to facilitate the installation and removal of the push rod. When the hydraulic jacks are pushed to the location of the roller to be replaced, they simultaneously drive the corresponding support rods to rise, causing the trays and push rods to rise as well. This allows the push rods to lift the transmission belt, completely detaching it from the roller, allowing the replacement roller to be removed. Then, a new roller is installed. Simultaneously, the hydraulic jacks simultaneously drive the corresponding support rods to descend, causing the push plate and push rods to descend, completely detaching the push rods from the transmission belt. After the replacement is completed, the tool is removed.

[0014] The length of the aforementioned push rod exceeds the width of the drive belt.

[0015] This application is easy to operate. It uses a hydraulic jack to drive the jack rod to lift the transmission belt containing the raw material, which enables quick replacement of rollers, saving time and effort and improving the efficiency of roller replacement.

[0016] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
