Description

Technical Field

[0001] This utility model relates to the field of coking technology, specifically to a tamping machine for coking experiments. Background Technology

[0002] In the coking process, coal compaction is a crucial step. The quality of coal compaction directly affects the quality and properties of coke, such as its strength and abrasion resistance. Currently, existing coking compaction machines used in experimental coking applications have some shortcomings in practical applications.

[0003] During tamping operations, the reverse impact force generated when the tamping hammer comes into contact with the coal directly acts on the relevant components of the equipment. Long-term use can easily cause damage to these components, such as deformation of the protective shell and loosening of connecting parts. Moreover, the lack of an effective buffering mechanism makes it difficult for the tamping hammer to maintain a stable posture when subjected to impact, affecting the uniformity and accuracy of tamping and further reducing the tamping effect. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a tamping machine for coking experiments, which solves the problem that the reverse impact force generated when the tamping hammer comes into contact with the coal material can cause damage to these components.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tamping machine for coking experiments, comprising a fixed cylinder, a telescopic cylinder fixedly connected to the top of the fixed cylinder, a lever fixedly connected to the bottom of the telescopic cylinder, a sliding rod slidably connected to the inner wall of the fixed cylinder, a sliding block fixedly connected to the outer side of the sliding rod, and a compression spring fixedly connected to the top of the sliding block; further comprising: a striking assembly, the top of which is fixedly connected to the bottom of the sliding rod, the striking assembly including a protective shell, a tamping hammer fixedly connected to the bottom of the protective shell, a limit rod fixedly connected to the inner side of the protective shell, and a buffer block slidably connected to the outer wall of the limit rod. During tamping operations, the tamping hammer will withstand a large impact force. When the tamping hammer contacts the coal, the reverse impact force of the coal on the tamping hammer will be transmitted to the inner side of the protective shell.

[0008] Preferably, a limiting sleeve is fixedly connected to the outer side of the sliding block, and a wedge-shaped stop is slidably connected to the inner side of the limiting sleeve. A return spring is fixedly connected to the outer side of the wedge-shaped stop, and the outer side of the return spring is fixedly connected to the inner wall of the sliding block. When the lever disengages from the wedge-shaped stop, the return spring drives the wedge-shaped stop to return to its original position. Subsequently, the telescopic cylinder retracts, causing the lever to move upward. At this time, the upward-moving lever can drive the sliding block to move together through the wedge-shaped stop and the limiting sleeve.

[0009] Preferably, the outer side of the lever is slidably connected to the inner side of the fixed cylinder, the outer side of the sliding block is slidably connected to the inner side of the fixed cylinder, and the inner side of the fixed cylinder is fixedly connected to the top of the compression spring. When the spring force of the compression spring is released, the tapping assembly can be driven to tap downwards quickly through the sliding block and the sliding rod.

[0010] Preferably, a rod is fixedly connected to the top of the inner wall of the fixed cylinder. The bottom of the rod is inserted into the inner wall of the limiting sleeve through a hole, and the hole is opened in the wall of the limiting sleeve. The bottom of the rod is slidably connected to the inner wall of the wedge-shaped block through a slot, and the slot is opened in the wall of the wedge-shaped block. When the limiting sleeve moves to the upper stop point, the bottom of the rod will be inserted into the hole and then into the slot. At this time, under the mutual pressing action of the rod and the inclined surface of the slot, the wedge-shaped block retracts back into the limiting sleeve, so that the bottom of the wedge-shaped block is separated from the top of the lever.

[0011] Preferably, the top of the protective shell is fixedly connected to the bottom of the sliding rod, the limiting rod is arranged in a ring along the central axis of the protective shell, and the buffer block is arranged linearly along the central axis of the limiting rod. The reverse impact force of the coal material on the tamping hammer will be transmitted to the inner side of the protective shell, thereby causing the buffer block to slide upward along the limiting rod, consuming and dispersing part of the impact force.

[0012] (III) Beneficial Effects

[0013] This utility model provides a tamping machine for coking experiments. It has the following beneficial effects:

[0014] (i) The tamping machine is equipped with a wedge-shaped stop. When the limiting sleeve reaches the upper stop, the wedge-shaped stop retracts into the limiting sleeve under the mutual squeezing action of the insert rod and the inclined surface of the slot. This causes the bottom of the wedge-shaped stop to separate from the top of the push block. At this time, the elastic force of the compression spring is released, and the tamping component is driven to strike downwards quickly through the sliding block and sliding rod. This provides a strong instantaneous impact force to the tamping hammer, enhances the tamping effect, helps to make the coal more compact, increases the bulk density of the coal, and thus affects the quality and performance of the final coke.

[0015] (ii) By setting up a striking component, the tamping machine will withstand a large impact force during the tamping operation. When the tamping hammer comes into contact with the coal, the reverse impact force of the coal on the tamping hammer will be transmitted to the inside of the protective shell, which will cause the buffer block to slide upward along the limit rod, consuming and dispersing part of the impact force and extending the service life of the key components of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-4This utility model provides a technical solution: a tamping machine for coking tests, including a fixed cylinder 1, a telescopic cylinder 2 fixedly connected to the top of the fixed cylinder 1, a lever 5 fixedly connected to the bottom of the telescopic cylinder 2, a sliding rod 3 slidably connected to the inner wall of the fixed cylinder 1, a sliding block 6 fixedly connected to the outer side of the sliding rod 3, and a compression spring 7 fixedly connected to the top of the sliding block 6. It also includes: a limiting sleeve 8 fixedly connected to the outer side of the sliding block 6, a wedge-shaped stop 9 slidably connected to the inner side of the limiting sleeve 8, a return spring 10 fixedly connected to the outer side of the wedge-shaped stop 9, and the outer side of the return spring 10 fixedly connected to the inner wall of the sliding block 6. The outer side of block 5 is slidably connected to the inner side of fixed cylinder 1, the outer side of sliding block 6 is slidably connected to the inner side of fixed cylinder 1, the inner side of fixed cylinder 1 is fixedly connected to the top of compression spring 7, and a rod 13 is fixedly connected to the top of the inner wall of fixed cylinder 1. The bottom of rod 13 is inserted into the inner wall of limiting sleeve 8 through insertion hole 12, and insertion hole 12 is opened in the wall of limiting sleeve 8. The bottom of rod 13 is slidably connected to the inner wall of wedge-shaped stop 9 through slot 11, and slot 11 is opened in the wall of wedge-shaped stop 9. The device is installed on the top of coal silo. When tamping operation is required, telescopic cylinder 2 is activated first. The lever 5 slides downward inside the fixed cylinder 1. When the lever 5 contacts the inclined surface of the wedge-shaped stop 9 during its downward movement, the wedge-shaped stop 9 is squeezed into the limiting sleeve 8. At this time, the return spring 10 is compressed. When the lever 5 disengages from the wedge-shaped stop 9, the return spring 10 drives the wedge-shaped stop 9 to return to its original position. Then, the telescopic cylinder 2 retracts, causing the lever 5 to move upward. At this time, the upward-moving lever 5 can drive the sliding block 6 to move together through the wedge-shaped stop 9 and the limiting sleeve 8. At this time, the sliding block 6 drives the striking component 4 to move upward synchronously through the sliding rod 3, and the compression spring 7 stores force. When the limiting sleeve 8 reaches the upper stop... At this point, the bottom of the insert rod 13 will be inserted into the insertion hole 12, and then into the slot 11. Under the mutual squeezing action of the insert rod 13 and the inclined surface of the slot 11, the wedge-shaped stop 9 will retract back into the limiting sleeve 8, so that the bottom of the wedge-shaped stop 9 will disengage from the top of the push block 5. At this time, the elastic force of the compression spring 7 will be released, and the tack assembly 4 will be driven to strike downwards quickly through the sliding block 6 and the sliding rod 3. This energy storage and release mechanism provides a strong instantaneous impact force for the tamping hammer 42, enhances the tamping effect, helps to make the coal more compact, increases the bulk density of the coal, and thus affects the quality and performance of the final coke.

[0023] The tamping assembly 4 is fixedly connected at its top to the bottom of the sliding rod 3. The tamping assembly 4 includes a protective shell 41, with a tamping hammer 42 fixedly connected to the bottom of the protective shell 41. A limit rod 43 is fixedly connected to the inner side of the protective shell 41, and a buffer block 44 is slidably connected to the outer wall of the limit rod 43. The top of the protective shell 41 is fixedly connected to the bottom of the sliding rod 3. The limit rod 43 is arranged in a ring along the central axis of the protective shell 41, and the buffer block 44 is arranged linearly along the central axis of the limit rod 43. During tamping operations, the tamping hammer 42 will withstand a large impact force. When the tamping hammer 42 comes into contact with the coal, the reverse impact force from the coal is transmitted to the inner side of the protective shell 41, causing the buffer block 44 to slide upwards along the limit rod 43, consuming and dispersing some of the impact force and extending the service life of key components of the equipment.

[0024] When in use, the device is installed on the top of the coal silo. When tamping is required, the telescopic cylinder 2 is activated first. The telescopic cylinder 2 drives the paddle block 5 to slide downward inside the fixed cylinder 1. When the paddle block 5 contacts the inclined surface of the wedge-shaped stop 9 during its downward movement, the wedge-shaped stop 9 is squeezed into the limiting sleeve 8. At this time, the return spring 10 is compressed. When the paddle block 5 separates from the wedge-shaped stop 9, the return spring 10 drives the wedge-shaped stop 9 to reset. Then the telescopic cylinder 2 retracts and drives the paddle block 5 to move upward. At this time, the upward-moving paddle block 5 can drive the sliding block 6 to move together through the wedge-shaped stop 9 and the limiting sleeve 8. At this time, the sliding block 6 drives the striking component 4 to move upward synchronously through the sliding rod 3, and the compression spring 7 stores force.

[0025] When the limiting sleeve 8 reaches its upper stop, the bottom of the insert rod 13 will insert into the insertion hole 12 and then into the slot 11. At this time, under the mutual squeezing action of the insert rod 13 and the inclined surface of the slot 11, the wedge block 9 retracts back into the limiting sleeve 8, causing the bottom of the wedge block 9 to separate from the top of the push block 5. At this time, the elastic force of the compression spring 7 is released, and the tack assembly 4 is driven to strike downwards quickly through the sliding block 6 and the sliding rod 3. This energy storage and release mechanism provides a strong instantaneous impact force for the tamping hammer 42, enhances the tamping effect, helps to make the coal more compact, increases the bulk density of the coal, and thus affects the quality and performance of the final coke.

[0026] During tamping operations, the tamping hammer 42 will be subjected to a large impact force. When the tamping hammer 42 comes into contact with the coal, the reverse impact force of the coal on the tamping hammer 42 will be transmitted to the inside of the protective shell 41, which will cause the buffer block 44 to slide upward along the limit rod 43, consuming and dispersing part of the impact force and extending the service life of key components of the equipment.
