Description

Technical Field

[0001] This utility model relates to the technical field of batching scale calibration equipment, and in particular to an automatic calibration device for batching scale weights. Background technology:

[0003] The raw materials for calcium carbide production are semi-coke or coke and quicklime. To ensure the production quality of calcium carbide, the addition of semi-coke and quicklime requires precise batching. During batching, quicklime balls are added quantitatively to the silo, which is equipped with an electronic scale to precisely control the proportion of quicklime balls. In actual use, each shift of operators needs to use weights to calibrate the scale before batching to ensure the accuracy of the batching. The weights weigh 0.5 tons. Currently, the scale calibration requires overhead crane to hoist and place them, which is labor-intensive, inefficient, and poses safety hazards such as falls from heights and injuries from falling weights during handling. This needs to be improved urgently. Utility Model Content

[0006] Furthermore, the connecting column assembly includes a vertically arranged connecting column, the top of which is connected to the wire rope, a limiting plate is connected to the bottom of the connecting column, and an inverted conical guide cone is installed at the bottom of the limiting plate.

[0007] Furthermore, the positioning seat assembly includes a guide seat, with a tapered through hole at the center of the guide seat that matches the guide cone, and several support legs mounted vertically downwards on the guide seat.

[0008] Furthermore, the guide plate is mounted on the connecting column, and sliding grooves are provided on both sides of the connecting column, the sliding grooves being slidably connected to the guide rail.

[0009] Furthermore, a limit cylinder is horizontally installed on the outer wall of the guide rail, and a through hole is horizontally opened on the guide rail. The piston rod of the limit cylinder is slidably connected to the through hole.

Detailed Implementation

[0015] like Figure 1 As shown, an automatic calibration device for weights on a batching scale includes a horizontally arranged frame 1. Two guide rails 3 are vertically connected downwards on the frame 1. A connecting column assembly is vertically arranged between the two guide rails 3. The top of the connecting column assembly is connected to the wire rope 4 of a winch 2. The winch 2 is fixedly installed on the frame 1. Several guide plates 7 are horizontally installed on the connecting column assembly. The guide plates 7 are slidably connected to the guide rails 3. Several weights 6 are placed on the connecting column assembly. A positioning seat assembly matching the connecting column assembly is arranged directly below the connecting column assembly.

[0016] like Figure 2 As shown, the connecting column assembly includes a vertically arranged connecting column 5, the top of which is connected to the wire rope 4, a limiting plate 8 is connected to the bottom of the connecting column 5, and an inverted conical guide cone 9 is installed at the bottom of the limiting plate 8; the positioning seat assembly includes a guide seat 10, a conical through hole 11 matching the guide cone 9 is opened at the center of the guide seat 10, and several support legs 14 are vertically installed on the guide seat 10.

[0017] like Figure 1As shown, the guide plate 7 is installed on the connecting column 5, and a sliding groove 13 is provided on both sides of the connecting column 5. The sliding groove 13 is slidably connected to the guide rail 3. In order to prevent the weight 6 from falling, a limiting cylinder 12 is horizontally installed on the outer wall of the guide rail 3. A through hole is horizontally provided on the guide rail 3, and the piston rod of the limiting cylinder 12 is slidably connected to the through hole.

[0018] like Figures 1 to 3 As shown, the frame 1 is fixedly installed on the platform. During calibration, the guide seat 10 is placed on the batching scale tray. The forward-rotating winch 2 causes the connecting column 5 to drive the weight 6 down until the guide cone 9 is fully inserted into the conical through hole 11. After calibration, the reverse-rotating winch 2 lifts the weight 6. The limit cylinder 12 can be activated so that the piston rod of the limit cylinder 12 passes through the through hole, thereby braking the guide plate 7 and preventing the weight 6 from falling.
