Description

Technical Field

[0001] This utility model relates to the field of special equipment for tamping coke oven machinery and equipment, specifically to a special lifting tool for tamping hammers. Background Technology

[0002] The tamping hammer is one of the key components of a tamping machine, mainly composed of friction plates, a hammer rod, and a hammer head. The hammer rod and hammer head are welded structures, and this welded assembly is referred to in the industry as the "tamping hammer rod." The friction plates are bonded to the tamping hammer rod using adhesive and a curing agent. The tamping hammer is required in all side-loading tamping coke ovens. The length and other dimensions of the tamping hammer vary depending on the coal cake size set for different types of metallurgical coke ovens. Generally, in currently operating tamping coke ovens, the length of a single tamping hammer typically ranges from 8.5 to 11.5 meters, and its weight ranges from 400 to 500 kg.

[0003] Tamping hammers are slender workpieces requiring high overall straightness, typically designed to be + / - 2mm. During the welding of the tamping hammer rod, bonding of the friction plates, transportation, and installation, a crane is required to lift it and transport it to the designated working position. However, due to its length, some existing lifting tools or fixtures are prone to uneven stress along the length of the tamping hammer rod during lifting, leading to instability or bending deformation of the hammer rod. When the bending deformation exceeds 2mm, the tamping hammer can be rendered unusable. After-sales data feedback indicates that significant bending deformation can also cause the friction plates to detach, resulting in tamping hammer failure.

[0004] To effectively solve this problem, it is necessary to design and provide a special lifting tool for tamping hammers, hence this application is submitted. Utility Model Content

[0005] To solve the above problems, this utility model provides a special lifting tool for tamping hammers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A special lifting tool for a tamping hammer includes a lifting chain, a tamping hammer, and a lifting device. The lifting device includes a boom, and at least two sets of clamping assemblies are provided at the bottom of the boom. Each clamping assembly includes a fixed structure and two sets of rotating structures. The fixed structure includes a mounting plate, and ear plate assemblies are welded to the bottom of both sides of the mounting plate. Each ear plate assembly includes two downward-facing and parallel ear plate pieces. The upper part of the mounting plate is welded to the bottom of the boom. The ear plate pieces are provided with hinge holes and locking holes. The rotating structures include a rotating plate and a clamping base plate, and the rotating plate is provided with hinge holes and locking holes.

[0008] Preferably, the boom is distributed horizontally, and two symmetrical lifting lugs are welded to the boom, with the lifting lugs connected to the lifting chain.

[0020] To make the objectives and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1-5 As shown in the figure, the present invention provides a special lifting tool for a tamping hammer, including a lifting chain 3, a tamping hammer 2, and a lifting device 1. The lifting device 1 includes a boom 11, and at least two sets of clamping components are provided at the bottom of the boom 11. The clamping components include a fixing structure 12 and two sets of rotating structures 13. The fixing structure 12 includes a mounting plate 121, and ear plate assemblies 122 are welded to the bottom of both sides of the mounting plate 121. The ear plate assembly 122 includes two downward and parallel ear plate pieces 1221. The upper part of the mounting plate 121 is welded to the bottom of the boom 11. The ear plate pieces 1221 are provided with hinge holes 123 and locking holes 124. The rotating structure 13 includes a rotating plate 131 and a clamping base plate 135. The rotating plate 131 is provided with hinge holes 123 and locking holes 124.

[0022] In the above structure, at least two sets of clamping components are provided at the bottom of the boom 11. Preferably, three sets of clamping components are provided. The distance between adjacent clamping components is the same, which can effectively prevent the tamping hammer 2 from being subjected to uneven force during the hoisting process, thus preventing hoisting instability or bending deformation.

[0023] Furthermore, the boom 11 is distributed horizontally, and two symmetrical lifting lugs 111 are welded to the boom 11. The lifting lugs 111 are connected to the lifting chain 3.

[0024] Furthermore, the rotating plate 131 is inserted upward into the middle position of the two parallel ear plates 1221, and the hinge holes 123 and locking holes 24 on the rotating plate 131 and the two ear plates 1221 all fit together.

[0025] In the above structure, the hinge hole 123 and the locking hole 24 are both machined and formed. After they fit together, the hinge hole 123 is connected by inserting the hinge shaft, and the locking hole 24 is connected by inserting the locking pin. Without installing the locking pin, rotation can be achieved to facilitate hoisting and demolding.

[0026] Furthermore, one side of the rotating plate 131 is provided with an anti-slip side plate 134, and the clamping base plate 135 is provided with an anti-slip base plate 136.

[0027] Furthermore, the height dimension X of the anti-slip side plate 134 is greater than or equal to the height of the tamping hammer 2.

[0028] Furthermore, the distance X between the two anti-slip side plates 134 is equal to the width of the tamping hammer 2 plus 3mm.

[0029] Working principle:

[0030] The tamping hammer 2 is placed horizontally on at least two sets of clamping components. After determining the distance, a locking pin is inserted into the shaft locking hole 124 to lock it in place. This locks the rotating structure 13 as a whole during hoisting, preventing the tamping hammer 2 from shaking and falling during hoisting. One side of the rotating plate 131 is provided with an anti-slip side plate 134, and the clamping base plate 135 is provided with an anti-slip base plate 136. Both the anti-slip side plate 134 and the anti-slip base plate 136 are made of high-polymer anti-slip material. The anti-slip side plate 134 contacts the side of the tamping hammer 2, and the anti-slip base plate 136 contacts the bottom surface of the tamping hammer 2, preventing the tamping hammer 2 from slipping or being damaged during hoisting.

[0031] In summary, this utility model effectively prevents uneven force on the tamping hammer 2 during hoisting, thus avoiding instability or bending deformation. By setting up the fixed structure 12 and two sets of rotating structures 13, it can be applied to the hoisting of tamping hammers 2 of different specifications and sizes. By setting up the anti-slip side plate 134 and anti-slip bottom plate 136, it effectively avoids slipping or damage to the tamping hammer 2 during hoisting, ensuring operational safety and product integrity.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
