Description

Technical Field

[0001] This utility model relates to the field of drill rod carburizing technology, and in particular to a drill rod carburizing device. Background Technology

[0002] Rock drill rods are essential tools in rock drilling and blasting. During the drilling process, they are subjected to huge impact loads and wear. The quality of heat treatment and carburizing of rock drill rods plays a crucial role in their service life.

[0003] In the carburizing process of drill rods, traditional carburizing devices typically use horizontal stacking or simple suspension to place the drill rods. This method has the following problems:

[0004] 1. Currently, most drill rods are suspended using ceramic fiber ropes, which makes the drill rods very prone to swinging inside the carburizing furnace. In severe cases, the drill rods may even fall off due to collision.

[0005] 2. Existing suspension rods are cumbersome to operate, manual fixing is inefficient, and it is difficult to ensure the verticality of the rods, which can easily lead to deformation.

[0006] 3. When the drill rod is placed horizontally, the contact area between the drill rod and the material rack increases, which seriously affects the carburizing effect of the drill rod;

[0007] Therefore, there is an urgent need for a drill rod carburizing device that can overcome the above-mentioned shortcomings. Utility Model Content

[0008] To overcome the shortcomings of the prior art, this utility model discloses a drill rod carburizing device. This utility model not only enables convenient and efficient vertical lifting of the drill rod, but also significantly reduces the contact area of ​​the drill rod when it is placed horizontally, greatly improving the carburizing efficiency and quality.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A carburizing device for a drill rod includes a top plate and a bottom plate arranged parallel to each other. Several support rods for fixing and supporting the top plate are evenly distributed on the outer edge of the upper surface of the bottom plate. Several openings penetrating the top plate and arranged in an orderly manner along the same axis are also provided on the upper surface of the top plate. A clamping mechanism for vertically clamping the drill rod is provided in the opening. The clamping mechanism includes a fixed clamping plate fixedly installed on the inner wall of one side of the opening and a movable clamping plate that can slide and adjust towards the fixed clamping plate. A cover plate for sealing the opening and which is on the same plane as the upper surface of the top plate is detachably installed on the upper part of the opening. Several protruding ribs with triangular cross-sections and arranged in parallel and equidistantly are provided on the upper surfaces of the top plate, the cover plate, and the bottom plate.

[0011] Furthermore, one side of the convex ridge is provided with several vent holes that penetrate the convex ridge along its axial direction.

[0012] Furthermore, a drive rod is provided on one side of the top plate, which sequentially moves through several openings containing fixed clamping plates and movable clamping plates. Each drive rod in the opening has a thread for driving the movable clamping plate to move along the drive rod axis. One end of the drive rod extends to the outside of the top plate and has a handle at its end.

[0013] Furthermore, a guide rod is provided on one side of the top plate, which is parallel to and corresponds to the drive rod and moves through several openings containing movable clamping plates and fixed clamping plates in sequence.

[0014] Furthermore, both the fixed clamping plate and the movable clamping plate have an arc-shaped notch in the middle of their opposite surfaces, and the drive rod and guide rod are located on both sides of the arc-shaped notch.

[0015] Furthermore, a ceramic gasket or a graphite gasket is provided on the inner surface of the arc-shaped notch.

[0016] Furthermore, the upper side of the inner cavity of the passage is provided with an enlarged opening that is compatible with the cover plate.

[0017] Furthermore, a partition with the same structure as the top plate is provided between the top plate and the bottom plate.

[0018] Furthermore, the top plate, partition plate and bottom plate are all provided with limiting blocks, and the lower end face of the limiting blocks is provided with toothed grooves that are adapted to the protruding ridges.

[0019] Furthermore, lifting lugs are provided at the top corners of the upper surface of the top plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By setting up openings and cover plates, the drill rod can be placed horizontally or suspended vertically according to the actual situation, providing strong support for the efficient carburization of the drill rod;

[0022] By setting up a clamping mechanism, the drill rod can be lifted vertically in a convenient and efficient manner, which not only provides support for the subsequent uniform carburizing operation of the drill rod, but also effectively avoids the deformation of the drill rod.

[0023] By setting up drive rods and guide rods, synchronous drive adjustment of multiple clamping mechanisms can be achieved, which greatly facilitates the batch suspension operation of the same type of drill rod;

[0024] By setting ridges and ventilation holes, the contact area of ​​the drill rod can be greatly reduced during horizontal placement, and the smooth flow of carburizing gas can be ensured, which provides strong support for uniform carburizing of the drill rod.

[0025] By setting ceramic or graphite gaskets, uneven carburization caused by direct contact between the clamping mechanism and the drill rod can be effectively avoided;

[0026] This invention not only enables convenient and efficient vertical lifting of the drill rod, but also greatly reduces the contact area of ​​the drill rod when it is placed horizontally, providing strong support for efficient and uniform carburizing of the drill rod and significantly improving the carburizing efficiency and quality of the drill rod.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0033] Please refer to the instruction manual appendix. Figure 1-4 This utility model provides a technical solution:

[0034] Example 1: A carburizing device for a drill rod includes a top plate 2 and a bottom plate 10 arranged parallel to each other. Several support rods 4 for fixing and supporting the top plate 2 are evenly distributed along the outer edge of the upper surface of the bottom plate 10. The top corner of the upper surface of the top plate 2 is provided with lifting lugs 1 for easy hoisting. The upper surface of the top plate 2 also has several through-holes 3 that penetrate the top plate 2 and are arranged in a coaxial, orderly spaced manner. A clamping mechanism 8 for vertically clamping the drill rod is provided within each through-hole 3. The clamping mechanism 8 includes a fixed clamping plate 14 fixedly installed on the inner wall of one side of the through-hole 3, and a movable clamping plate 13 that can slide and adjust towards the fixed clamping plate 14. An arc-shaped recess 15 is provided in the middle of the opposite surface of both the fixed clamping plate 14 and the movable clamping plate 13. A ceramic gasket or graphite is provided on the inner surface of the arc-shaped recess 15. Specifically, in order to achieve synchronous drive adjustment of the clamping mechanism 8 in multiple through-holes 3 and meet the batch clamping and carburizing operation of the same model of drill rod, a drive rod 16 is provided on one side of the top plate 2, which sequentially moves through the fixed clamping plate 14 and the movable clamping plate 13 in several through-holes 3. Each drive rod 16 in each through-hole 3 is provided with a thread for driving the movable clamping plate 13 to move along the axial direction of the drive rod 16. One end of the drive rod 16 extends to the outside of the top plate 2 and has a handle 17 at its end. A guide rod 18 is also provided on one side of the top plate 2, which is parallel to the drive rod 16 and sequentially moves through the movable clamping plate 13 and the fixed clamping plate 14 in several through-holes 3. The drive rod 16 and the guide rod 18 are located on both sides of the arc-shaped recess 15.

[0035] If the length of the drill rod is greater than 1.5m, in order to avoid the drill rod from being deformed by heat during the carburizing process, the staff removes the cover plate 6, places the drill rod vertically in the through opening 3, first places the end of the drill rod against the arc-shaped recess 15 of the fixed clamping plate 14, and after the drill rod is clamped by the sliding adjustment movable clamping plate 13, the vertical suspension of the drill rod can be completed.

[0036] In Example 2, if the length of the drill rod is less than 1.5m, the probability of carburizing deformation is relatively small. Therefore, in order to reduce the workload of the workers and increase the amount of carburizing of the drill rod, most drill rods less than 1.5m are placed horizontally. For this purpose, an enlarged diameter port 12 is provided on the upper side of the inner cavity of the through port 3. The enlarged diameter port 12 is provided with a cover plate 6 for sealing the through port 3 and is on the same plane as the upper surface of the top plate 2. The cover plate 6 can ensure that the top plate 2 is a complete plane, which facilitates the subsequent horizontal placement of the drill rod.

[0037] When the drill rod is placed horizontally, the contact area of ​​the drill rod is large, which affects the uniformity of its carburizing. To address this, the upper surfaces of the top plate 2 and the cover plate 6, as well as the upper surface of the bottom plate 10, are provided with several protruding ribs 5 with triangular cross sections and arranged in parallel at equal intervals. The horizontal support of the drill rod by the protruding ribs 5 can greatly reduce the contact area of ​​the drill rod. In order to enable the drill rod to fully contact the carburizing gas, several ventilation holes 11 are provided on one side of the protruding ribs 5, which penetrate the protruding ribs 5 along the axial direction of the protruding ribs 5.

[0038] In Example 3, to prevent the drill rod from rolling and colliding during horizontal placement, both the top plate 2 and the bottom plate 10 are provided with limiting blocks 9. The lower end face of the limiting block 9 is provided with a toothed groove 19 that matches the protruding ridge 5. The limiting block 9 can be used to limit and fix the drill rod, preventing it from rolling and colliding during hoisting or carburizing.

[0039] In Example 4, to improve the carburizing efficiency of the drill rod, a partition 7 with the same structure as the top plate 2 is provided between the top plate 2 and the bottom plate 10. The openings 3 on the partition 7 correspond one-to-one with the openings 3 on the top plate 2. This not only greatly increases the number of drill rods that can be placed and hoisted, but also ensures the stability of the drill rod and prevents it from shaking and falling when vertically clamping a long drill rod.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
