Description

Technical Field

[0001] This utility model relates to the field of tamping tool technology, and in particular to a convenient-to-use carbide tamping tool. Background Technology

[0002] The tamping pick is a commonly used tool in railway maintenance and other work. It is mainly used to tamp the ballast in the track bed, so that the sleepers fit tightly with the track bed and ensure the stability of the railway track.

[0003] Replacing the head of a traditional tamping pick is cumbersome, usually requiring multiple tools such as wrenches and hammers, and going through several complicated steps. This not only wastes time but also increases maintenance costs and labor intensity. Therefore, we propose a convenient carbide tamping pick head to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a convenient carbide tamping tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A convenient carbide tamping pick includes: a tamping pick body, a ring-shaped handle on the outer side of the tamping pick body, a tamping rod fixedly installed at the output end of the tamping pick body, a connecting seat fixedly installed at the bottom of the tamping rod, an installation rod movably inserted into the bottom of the connecting seat, a pick head at the bottom of the installation rod, a carbide plate on the outer side of the bottom of the pick head, two sets of movable plates slidably installed inside the connecting seat, a locking block fixedly installed on one side of each of the two sets of movable plates, a first return spring fixedly installed on one side of each of the two sets of movable plates, movable blocks slidably installed inside each of the two sets of movable plates, an insert block fixedly installed at the bottom of each of the two sets of movable blocks, a second return spring fixedly installed at the top of each of the two sets of movable blocks, a pull rod fixedly installed on one side of each of the two sets of movable blocks, a connecting plate fixedly installed at one end of each of the two sets of pull rods, and a pull ring fixedly installed on one side of each of the two sets of connecting plates.

[0007] Preferably, the two sets of locking blocks are slidably installed inside the movable plate and movably inserted into the outside of the mounting rod; the two sets of insert blocks are slidably installed on one side of the corresponding movable plate and movably inserted into the inside of the connecting seat; and the two sets of pull rods are slidably installed on one side of the corresponding movable plate and one side of the connecting seat.

[0008] Preferably, the outer side of the annular grip is provided with anti-slip texture, and the outer side of the connecting rod is provided with two sets of slots, with the two sets of slots being movably inserted into the corresponding slots.

[0009] Preferably, the connecting seat has two sets of sliding grooves inside, the two sets of movable plates are slidably installed in the corresponding sliding grooves, and one end of each of the two sets of return springs is fixedly installed on one side of the corresponding sliding groove.

[0010] Preferably, both sets of movable plates are provided with limit grooves inside, the two sets of movable blocks are slidably installed in the corresponding limit grooves, and one end of each set of reset springs is fixedly installed on one side of the corresponding limit groove.

[0011] Preferably, the connector has two sets of slots inside, and the two sets of plugs are movably inserted into the corresponding slots.

[0012] In this utility model, a convenient carbide tamping pick is provided. The user holds the tamping pick body with a ring handle. The anti-slip texture on the outside of the ring handle increases the friction and prevents the tamping pick from slipping during use, providing stability for operation and effectively reducing the risk of the tamping pick slipping, thus providing more reliable safety for the operator.

[0013] This utility model features a reasonable structural design. A pull ring moves the connecting plate, pull rod, and moving block upwards under the constraint of the connecting seat and the moving plate. This causes the two sets of insert blocks to disengage from the slots, releasing the restriction on the moving plate. The return spring retracts, which in turn pulls the pull ring, causing the connecting plate, pull rod, moving block, and moving plate to move relative to each other within the slide groove. This allows the moving plate to disengage the locking block from the mounting rod, releasing the locking between the mounting rod and the pick. This allows for quick disassembly and replacement of the pick. To replace it, simply insert the mounting rod into the connecting seat, align the mounting rod's slot with the locking block, and then release. The handle, under the elastic force of return spring one and return spring two, allows the locking block to be inserted into the slot without external force, the moving plate to reset, and the insert block to be inserted into the slot to lock the moving plate, thus achieving dual locking of the mounting rod, pick head, and carbide plate. This enables quick installation of the mounting rod and pick head with the tamping rod, greatly reducing the time and effort spent on pick head replacement, effectively improving the maintenance efficiency of tamping picks, reducing equipment downtime, and ensuring the smooth operation of railway maintenance and other tasks. It is easy to apply to different models and specifications of pick heads, making it convenient for users to choose and use. Attached Figure Description

[0020] In this embodiment, two sets of locking blocks 9 are slidably installed inside the movable plate 8 and movably inserted into the outside of the mounting rod 5. Two sets of insert blocks 12 are slidably installed on one side of the corresponding movable plate 8 and movably inserted into the inside of the connecting seat 4. Two sets of pull rods 14 are slidably installed on one side of the corresponding movable plate 8 and one side of the connecting seat 4, which greatly saves installation time, reduces equipment downtime, and significantly improves work efficiency.

[0021] In this embodiment, the outer side of the ring handle 2 is provided with anti-slip texture, and the outer side of the connecting rod is provided with two sets of slots. The two sets of locking blocks 9 are movably inserted into the corresponding slots, reducing the risk of safety accidents caused by tool loss of control and ensuring the safety of operators.

[0022] In this embodiment, the connecting seat 4 has two sets of sliding grooves 17 inside, and two sets of moving plates 8 are slidably installed in the corresponding sliding grooves 17. One end of each of the two sets of return springs 10 is fixedly installed on one side of the corresponding sliding groove 17, ensuring smooth installation and improving the accuracy of tamping pick assembly.
