Description

Technical Field

[0001] This utility model relates to an offset clamp, belonging to the technical field of smelting equipment. Background Technology

[0002] During the unloading operation of industrial silicon submerged arc furnaces, robots need to perform processes such as opening holes, slag removal, plugging holes, and cleaning furnace tongues. Natural wooden sticks are usually used on-site for slag removal. However, existing clamping tools have high requirements for the specifications and dimensions of the wooden sticks and cannot adapt well to irregular changes in the diameter and straightness of the wooden sticks. This causes the wooden sticks to move axially or even fall off during slag removal with the rod attached, thus affecting work efficiency. In addition, in order to adapt to existing clamping tools, the wooden sticks usually need to be shortened before use, which requires frequent replacement of wooden sticks during slag removal operations, reducing work efficiency. Utility Model Content

[0003] To address the problems of poor adaptability and low efficiency of existing slag discharge clamping tools during furnace tapping operations, this utility model proposes an offset clamping device. It includes a tapered mounting joint with a clamping mechanism on its side. The horizontal centerline of the mounting joint is parallel to the horizontal centerline of the clamping mechanism. The clamping mechanism includes a bottom cover and a top cover, both semi-circular in shape and hinged at one end. The other end of the bottom cover has at least one set of locking rings, and the other end of the top cover has a locking hook that cooperates with the locking rings. The top cover has at least one set of threaded sleeves, with toothed pressure blocks inside. The upper part of the threaded sleeves is connected to a clamping screw, and the lower end of the clamping screw is connected to the upper end of the toothed pressure blocks. The bottom cover has a clamping rack inside.

[0004] The clamping mechanism is mounted on a horizontal adjustment device, which is used to adjust the clamping mechanism forward and backward. The horizontal adjustment device can be driven by a power source or manually.

[0005] The horizontal adjustment device is a guide rail drive mechanism, which includes a guide rail base connected to a mounting joint via a connecting bracket. The guide rail base has symmetrically arranged horizontally arranged guide rails on its left and right sides. A moving trolley is located at the lower end of the clamping mechanism. A sprocket mechanism is located on the front and rear sides of the guide rail base, driven by a chain. The head and tail of the chain are connected to the front and rear ends of the moving trolley, respectively. A ratchet and a handwheel are sequentially arranged on the coaxial axis of at least one of the sprocket mechanisms. The ratchet is locked by a pawl, which is hinged to the guide rail base. A tension spring is mounted on the pawl, with the other end of the spring installed on the guide rail base. Rotating the handwheel allows the clamping mechanism to roll forward along the guide rail.

[0006] The guide rail seat is also provided with a pawl limiting hole, and the pawl is provided with a pin hole. When the pin hole and the pawl limiting hole are concentric, the pin is inserted to disengage the pawl from the ratchet.

[0007] The horizontal adjustment device is a telescopic arm drive mechanism, which includes a primary fixed arm connected to a mounting joint via a connecting bracket. The front of the primary fixed arm has a fixed arm pin hole. A secondary telescopic arm is located inside the primary fixed arm, and a tertiary telescopic arm is located inside the secondary telescopic arm. At least two sets of limit pin holes are equidistantly provided on the tertiary telescopic arm. At least three sets of limit pin holes are provided on the secondary telescopic arm and are equidistant from the limit pin holes on the tertiary telescopic arm. When the secondary and tertiary telescopic arms retract, one set of limit pin holes in the secondary and tertiary telescopic arms is concentric with the fixed arm pin hole for inserting a limit pin. Limit pins can be inserted between the secondary and tertiary telescopic arms individually. A mounting support is provided at the upper front end of the tertiary telescopic arm, and a clamping mechanism is installed on the mounting support.

[0008] The beneficial effects of this utility model are: A. The clamping mechanism located on the side of the installation joint increases the clamping space for the wooden sticks, ensuring their utilization rate, reducing replacement cycles, and improving the efficiency of slag removal operations. The hinged locking method of the bottom and top covers better adapts to the curvature and irregular diameter variations of the natural wooden sticks. The downward movement of the toothed pressure block caused by the rotation of the clamping screw presses the toothed part into the wooden stick, and the toothed part of the clamping rack sinks into the wooden stick, preventing axial movement of the wooden stick during operation.

[0009] B. The horizontal adjustment device is used to move the clamping mechanism back and forth to cooperate with the wooden rod in the slag discharge operation, which extends the working space of the wooden rod, further improves the utilization rate of the wooden rod, and improves the overall work efficiency.

[0010] C. By utilizing the ratchet and pawl on the coaxial part of the handwheel, the clamping mechanism moves the wooden stick to the appropriate position. During slag discharge, the position of the wooden stick can be locked to prevent it from moving backward and affecting the operation, thus improving the reliability of the equipment.
