Description

Technical Field

[0001] This utility model relates to a proximity switch installation structure for a steel loading machine in a heating furnace, belonging to the technical field of steel smelting equipment. Background Technology

[0002] The function of the charging and unloading machine in a heating furnace is to load steel plates from the charging rollers into the furnace and then lift them out onto the unloading rollers. The stroke of the charging and unloading machine is calculated by an incremental encoder on the motor. Signals from a zero-position proximity switch are used to zero-point the machine for each operating cycle, eliminating errors. Signals from limit position proximity switches control the safety position protection during movement. The proximity switch used for position detection of the charging arm is a widely used detection element in the steel industry and is crucial for controlling the machine's operation.

[0003] Currently, the installation of proximity switches for the steel unloading machine in the heating furnace has the following disadvantages:

[0004] 1) During the horizontal movement of the steel loading arm of the heating furnace, there is a gap and sway in the direction perpendicular to the steel loading arm, which causes the proximity switch to be damaged.

[0005] 2) The proximity switch is easily damaged during the process of adjusting the zero position proximity switch and replacing the proximity switch during the test run.

[0006] All of the above lead to increased equipment failure and maintenance costs. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a proximity switch installation structure for a steel loading machine in a heating furnace, which avoids damage to the proximity switch, improves service life, and reduces maintenance costs.

[0008] The technical solution adopted by this utility model to solve the above problems is as follows: a proximity switch installation structure for a steel charging machine in a heating furnace, including a baffle assembly and an adjustable bracket assembly. The baffle assembly is disposed on the side of the steel charging arm in the heating furnace, and an adjustable bracket assembly is disposed below the baffle assembly. Two proximity switches are disposed on the adjustable bracket assembly, and the baffle assembly blocks the proximity switches. The adjustable bracket assembly is used to adjust the position of the two proximity switches.

[0009] The baffle assembly includes a fixed baffle, one side of which is fixed to the side of the steel arm that is being loaded from the heating furnace. A movable baffle is provided below the fixed baffle. Two vertically penetrating fourth adjustment slots are symmetrically opened on the fixed baffle. When the movable baffle is moved into position, connecting bolts are respectively inserted into the fourth adjustment slots and pass through the movable baffle. Connecting bolts are screwed into the bottom of the connecting bolts, so that the movable baffle is connected to the fixed baffle.

[0010] The adjustable bracket assembly includes a fixed bracket and a movable bracket below the fixed bracket. The fixed bracket has two symmetrically arranged first adjustment slots, and the movable bracket has two symmetrically arranged third adjustment slots. The first adjustment slots correspond to the third adjustment slots. The movable bracket moves horizontally and longitudinally along the bottom surface of the fixed bracket. Fixing bolts are respectively inserted into the first adjustment slots and pass through the third adjustment slots. Fixing nuts are screwed into the bottom of the fixing bolts to connect the movable bracket to the fixed bracket. The movable bracket has a horizontally arranged second adjustment slot, and the two proximity switches are disposed in the second adjustment slot.

[0011] The movable baffle is made of thin sheet metal.

[0012] Compared with the prior art, the advantages of this utility model are: a proximity switch installation structure for a heating furnace steel loading machine is easy to install; the baffle assembly blocks the proximity switch, preventing damage to the proximity switch, improving the service life of components, thereby reducing spare parts costs, reducing equipment failures, and thus improving equipment and personnel safety.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 3As shown in this embodiment, a proximity switch mounting structure for a heating furnace charging machine includes a baffle assembly and an adjustable bracket assembly. The baffle assembly is located on the side of the charging arm 12 of the heating furnace, and the adjustable bracket assembly is located below the baffle assembly. The adjustable bracket assembly has two proximity switches 6: a zero-position proximity switch and an extreme proximity switch. The baffle assembly shields the two proximity switches 6, providing protection. The zero-position and extreme proximity switches can move within the adjustable bracket assembly, thereby adjusting their positions and better calibrating the zero and extreme positions.

[0019] like Figure 2 As shown, the baffle assembly includes a fixed baffle 8, one side of which is fixed to the side of the steel arm that is being loaded onto the heating furnace. A movable baffle 9 is located below the fixed baffle 8, and the movable baffle 9 can move horizontally across the bottom surface of the fixed baffle 8. Two vertically penetrating fourth adjustment slots 11 are symmetrically formed on the fixed baffle 8. After the movable baffle moves horizontally into position, connecting bolts 10 are respectively inserted into the fourth adjustment slots 11 and pass through the movable baffle 9. Connecting nuts are screwed onto the bottom of the connecting bolts, so that the movable baffle is fixed to the fixed baffle. When the position of the proximity switch changes, the horizontal position of the movable baffle is adjusted.

[0020] like Figure 1 As shown, the adjustable support assembly includes a fixed support 1, one side of which is fixed to the side of the steel arm being loaded from the heating furnace. A movable support 4 is located below the fixed support 1. Two symmetrically arranged first adjustment slots 2 are provided on the fixed support 1, and two symmetrically arranged third adjustment slots 7 are provided on the movable support 4, with the first adjustment slots 2 corresponding to the third adjustment slots 7. The movable support 4 can move horizontally longitudinally along the bottom surface of the fixed support 1, i.e., along the steel plate loading direction. After horizontal longitudinal movement to its designated position, fixing bolts 3 are inserted into the first adjustment slots 2, passing through the third adjustment slots, and fixing nuts are screwed into the bottom of the fixing bolts 3, thus fixing the fixed support 1 and the movable support 4. A horizontally arranged second adjustment slot 5 is provided on the movable support 4, and two proximity switches 6 are located within the second adjustment slot. The proximity switches can move within the second adjustment slot, realizing the adjustment of the proximity switches in the horizontal and vertical positions of the steel arm being loaded.

[0021] The aforementioned movable baffle is made of thin sheet metal. The sheet metal is less hard than the proximity switch, allowing it to deform and thus protect the proximity switch. It is malleable and can be quickly restored, or can be quickly disassembled and replaced.

[0022] This application is easy to install. The baffle assembly shields the proximity switch, preventing damage to the proximity switch, increasing the service life of components, reducing spare parts costs, reducing equipment failures, and thus improving equipment and personnel safety.

[0023] 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.
