Description

Technical Field

[0001] The utility model relates to the field of installation of tamping machines for coke ovens, and particularly relates to an auxiliary lifting tool for hoisting tamping hammers in tamping machines for coke ovens. Background Art

[0002] The tamping machine is placed on the fixed track in the operation room on the side of the coke oven coal tower. When the coal charging car enters the coal tower to take coal, the loose coal material falling into the coal chute is tamped into a coal cake with a certain strength, which is convenient for the coal charging car to send the coal cake into the carbonization chamber from the coke oven machine side. The tamping machine consists of the following parts: a frame, a safety stop device, a guide plate device, a main drive device, a hammer stop device, a tamping hammer, a wheel device, a tamping drive system, a centralized lubrication system, an electrical system, and a tamping hydraulic system. Among them, the tamping hammer is an important part of the tamping machine. Taking the 6.73-meter 38-hammer fixed tamping machine as an example, the single hammer weighs 480 kg and the hammer length is 10,850 mm. When hoisting, the tamping hammer needs to penetrate the frame and the guide plate device. The frame adopts a two-rail T-beam structure, which is divided into upper and lower parts and is connected by bolts. Each load-bearing beam has an I-shaped cross-section. The hammer stop device is fastened to the upper frame, while the main drive device, the wheel device, and the safety stop device are fastened to the lower frame. When each hammer rod moves up and down, it is guided by 6 rows of guide plate devices fastened to the frame. The upper 6 groups of guide plates on the same hammer rod need to be installed in combination with the cam suspension line to ensure that the 6 groups of guide plates are in the same vertical direction. The distance from the guide plate to the tamping hammer is initially adjusted to be no more than 3 mm, and the hoisting accuracy is high. The traditional lifting rings and lugs used for hoisting the tamping hammer are too large in volume to pass through the frame and the guide plate device. Therefore, it is necessary to design an auxiliary lifting tool for hoisting the tamping hammer in the tamping machine for coke ovens. Summary of the Utility Model

[0003] In view of the above-mentioned technical problems, an auxiliary lifting tool for hoisting the tamping hammer in the tamping machine for coke ovens is provided. The technical means adopted by the utility model are as follows:

[0004] An auxiliary lifting tool for hoisting the tamping hammer in the tamping machine for coke ovens includes a main body part. On one side in the length direction of the main body part, an installation hole is horizontally opened. On the other side in the length direction of the main body part, a wire rope through hole for installing a wire rope is vertically opened. Along the length direction of the main body part, an installation groove for installing the tamping hammer is vertically opened. One end of the installation groove penetrates the end of the main body part on the side of the installation hole, and there is a preset distance between the other end of the installation groove and the wire rope through hole.

[0005] Further, the main body of the main body part is of a cuboid structure, and its edges are provided with a preset radian, and its corners are provided with a preset rounded corner.

[0006] Further, the length of the main body part is 280 ± 10 mm, the width is 26 ± 5 mm, and an M12-7H threaded hole with a diameter of 24 mm is opened at a position 40 ± 5 mm away from one end.

[0007] Further, a 2-mm fillet is provided at the threaded hole.

[0008] Further, 8-mm fillets are made at both ends of the main body part.

[0009] Further, the overall inner diameters of the mounting holes are the same. On the side close to the tamping hammer to be installed, the mounting holes have a stepped chamfer with a gradually increasing diameter.

[0010] The utility model has the following advantages:

[0011] 1. The structure is reasonable, the cost is low, and the applicability is strong. Only one hoisting device is needed to meet the hoisting requirements of the tamping hammer, avoiding a large amount of production costs.

[0012] 2. It has strong operability and can quickly and stably complete the hoisting operation of the tamping hammer, effectively avoiding the problem that the gap between the frame and the guide plate is small and ordinary lifting tools cannot pass through. BRIEF DESCRIPTION OF THE DRAWINGS
