Description

Technical Field

[0001] The utility model relates to the field of metal smelting, in particular to a compact floor-standing transversely movable cover-lifting machine for moving a blast furnace taphole trench cover. Background Art

[0002] At present, the smoke and harmful gases emitted by the blast furnace of the steel company during the iron-making period are one of the main pollution sources of blast furnace production, among which the smoke near the iron-making hole of the blast furnace accounts for a considerable proportion, so the effective collection of smoke at the iron-making hole is directly related to the dust removal effect of the iron-making yard. There are generally top suction and side suction to collect smoke near the iron-making hole of the blast furnace, but since there is an open area near the iron-making hole, the smoke will run everywhere, so a trench cover needs to be placed on the iron trench near the iron-making hole to prevent the smoke from scattering and gather the smoke at the iron-making hole, so that the smoke can be better collected.

[0003] However, this trench cover will conflict with the movement trajectory of related equipment when opening and blocking the iron mouth. Therefore, when opening and blocking the iron mouth, this trench cover needs to be moved to a position where it does not affect the operation of related equipment. After the iron mouth is opened, the trench cover is moved above the iron trench. The equipment that moves this trench cover is a cover-lifting machine, and the existing cover-lifting machine has the following main defects: 1. The lifting device is located in the front of the walking trolley. Due to limited space, the lifting height is relatively low; 2. The lifting cylinder is at the front of the equipment, close to the molten iron, and is in a high temperature and high heat radiation position, which affects the service life of the cylinder; 3. The lifting cylinder follows the trolley to move long distances, so a longer hydraulic pipeline needs to be configured, which increases the requirements for replacement and maintenance; 4. The lifting arm is relatively short and is not suitable for trench covers with larger widths. Utility Model Content

[0026] The implementation scheme of the utility model will be described in detail below with reference to examples, but those skilled in the art will understand that the following examples are only used to illustrate the utility model and should not be regarded as limiting the scope of the utility model.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] The following description sets forth specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] refer to Figures 2 to 4 The present embodiment proposes a compact floor-standing transversely movable cover opening machine, comprising a basic base 1, a frame 2 is arranged at the upper end of the basic base 1, a transversely movable device 3 is arranged inside the frame 2, the front end of the transversely movable device 3 is fixedly connected to a hook, a lifting device 4 is arranged inside the basic base 1, the end of the frame 2 is rotatably connected to the end of the basic base 1, the upper end of the lifting device 4 is rotatably connected to the lower end of the frame 2, and the lower end is connected to the basic base 1.

[0030] In this embodiment, the lifting device 4 is arranged in the basic base 1, and the lifting device 4 cooperates with the transverse movement device 3, which can not only keep the lifting device 4 away from the iron hook, avoid high temperature and heat radiation, and improve the service life of the oil cylinder, but also increase the lifting height of the hook, and can also reduce the height of the entire cover opening machine, which is convenient for inspection and maintenance. At the same time, since the lifting device 4 is rearwardly arranged and the force arm of the transverse movement device 3 is lengthened, it can be suitable for a trench cover 7 with a larger width and a heavier weight. When the trench cover 7 is to be delivered to the iron trench 6, the transverse movement device 3 extends forward, and the hook passes through the trench cover 7 lifting lug to reach the specified position. The lifting device 4 is raised to lift the front end of the frame, thereby driving the hook to lift the trench cover 7 to a specified height, and the transverse movement device 3 continues to extend forward to deliver the trench cover 7 to the specified position above the iron trench 6. The lifting device 4 descends to cover the trench cover 7 on the iron trench 6. After the transverse movement device 3 is disengaged from the trench cover 7 lifting lug, it retracts to the specified position. The lifting device 4 continues to descend, driving the transverse movement device 3 back to the standby position, and the cover delivery process is completed. The cover removal process is opposite to the cover delivery process, which will not be repeated here.

[0031] refer to Figure 3 and Figure 4 Specifically, the transverse movement device 3 includes a transverse movement cylinder 301 and a retractable walking rail beam 302. The end of the walking rail beam 302 is fixedly connected to the end of the frame 2, and the front end passes through the frame 2 and is fixedly connected to the hook. The transverse movement cylinder 301 is arranged at the lower end of the walking rail beam 302, the front end is connected to the walking rail beam 302 through an ear shaft, and the end is connected to the frame 2 through an ear shaft. The lifting device 4 is preferably a lifting cylinder, the upper end of the lifting cylinder is connected to the lower end of the frame 2 through an ear shaft, and the lower end is fixedly connected to the base 1.

[0032] In this embodiment, when delivering the cover, the rodless cavity of the transverse oil cylinder 301 is filled with oil, pushing the walking rail beam 302 to extend forward, and the hook passes through the lifting ear of the ditch cover 7 to reach the specified position, and the rodless cavity of the lifting oil cylinder is filled with oil, pushing the front end of the frame 2 to rise, thereby driving the hook to lift the ditch cover 7 to the specified height, and the rodless cavity of the transverse oil cylinder 301 is filled with oil, continuing to push the walking rail beam 302 to extend forward, and delivering the ditch cover 7 to the specified position above the iron ditch 6, and the rod cavity of the lifting oil cylinder is filled with oil, and the lifting oil cylinder descends, driving the hook to cover the ditch cover 7 on the iron ditch 6, and the rod cavity of the transverse oil cylinder 301 is filled with oil, driving the walking rail beam 302 to retract backward to the specified position, and the rod cavity of the lifting oil cylinder is filled with oil, and the walking rail beam 302 descends to the standby position.

[0033] refer to Figure 2 and Figure 3 Specifically, the walking rail beam 302 and the four inner walls of the frame 2 are preferably slidably matched through the wheels 5, which can ensure that the walking rail beam 302 is stable and reliable during the extension and retraction process without shaking.

[0034] Specifically, a gap is opened in the middle of the bottom wall of the frame 2 along the movement direction of the walking rail beam 302, and the gap is located in the middle of the two train wheels 5 on the bottom wall. The transverse cylinder 301 is exposed from the gap and is located at the intersection of the frame 1 and the basic base 1, and the end is connected to the two sides of the gap on the bottom wall of the frame 2 through the ear shaft.

[0035] In this embodiment, when the transverse cylinder 301 is thicker, the internal space of the frame 2 is small, and the transverse cylinder 301 can be placed downward and set at the intersection of the frame 2 and the base 1, which can effectively reduce the height of the entire cover opening machine.

[0036] Furthermore, the transverse cylinder 301 and the lifting cylinder are both equipped with a balancing valve to avoid accidental cylinder failure during the operation. The outlets of the transverse cylinder 301 and the lifting cylinder are connected to the hard pipe through a short hose. Since the two cylinders have a certain rotation movement, there will be a shorter hose connection at the cylinder outlet, and the rest of the parts are connected by hard pipes. The equipment pipeline is located in the internal box of the basic base 1, with a simple layout, which is convenient for inspection and maintenance.

[0037] Although the utility model has been described in detail in this specification with general descriptions and specific implementation schemes, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model based on the utility model. Therefore, these modifications or improvements made without departing from the utility model are within the scope of protection claimed by the utility model.
