Description

Technical Field

[0001] This utility model relates to the technical field of drill rod movement structure of drilling rig, and in particular to a sliding plate floating structure. Background Technology

[0002] In integrated open-pit down-the-hole drilling rigs, a floating joint is typically installed between the rotary head and the drill rod during the connection and disconnection of drill rods to protect the drill rod threads. However, because the axial dimensions of the floating joint are relatively large, it is impossible to install it when the structural length is limited. Furthermore, in reverse circulation drilling rigs, a double-layer drill rod is used, and the floating joint structure is difficult to apply to the double-layer drill rod of reverse circulation drilling rigs. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a sliding plate floating structure, which can improve the convenience of drill rod installation and disassembly and extend the service life of drill rod.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A floating structure for a skateboard includes a skateboard, a chain mounting strip, and sliding components. Multiple sliding components are fixed to the bottom of the skateboard, allowing the skateboard to slide and engage with a guide rail. The chain mounting strip has a protrusion on its upper part, and the skateboard has an elongated through hole. The protrusion is embedded in the elongated through hole, and the length of the protrusion is less than the length of the elongated through hole. A retaining plate is also fixed to the upper end face of the protrusion, and the two sides of the retaining plate abut against the skateboard.

[0006] As a preferred embodiment, the length of the elongated through hole is 25-35 mm longer than the length of the protrusion.

[0007] As a preferred embodiment, the upper end face of the elongated through hole and the upper end face of the slide plate form an annular stepped surface, and the card plate rests against the stepped surface.

[0008] As a preferred embodiment, the two ends of the chain mounting bar are respectively provided with connecting hole A and connecting hole B. Connecting hole A is fixed to the driving roller chain at the end of the drive sprocket, and connecting hole B is fixed to the driving roller chain at the end of the driven sprocket.

[0009] As a preferred embodiment, the sliding assembly includes an upper friction reducing plate, a gasket, a lower friction reducing plate, and a pressure plate that are fixed in sequence by bolts. An elongated through groove is formed between the upper and lower friction reducing plates, and the through groove is engaged on the guide rail.

[0010] As a preferred embodiment, a rotary device is fixed to one end of the skateboard, and a hose fixing seat is fixed to the other end.

[0011] As a preferred embodiment, a rotary positioning plate is fixed on the slide plate, the rotary positioning plate is provided with a groove, and a rotary positioning sleeve is fixed to the bottom of the rotary, the rotary positioning sleeve is embedded in the groove and fixed by bolts.

[0012] As a preferred embodiment, a long strip-shaped rubber tube guard plate is also fixed to one side of the skateboard.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a long, narrow through-hole on the slide plate and a protrusion on the chain mounting bar. The protrusion can slide back and forth within the long, narrow through-hole, allowing the slide plate some room to move even when the chain mounting bar is stationary.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 3 As shown, a floating structure for a skateboard includes a skateboard 1, a chain mounting bar 2, and a sliding assembly. The chain mounting bar 2 has a protrusion 21 on its upper part, and the skateboard 1 has an elongated through hole 11. The protrusion 21 is embedded in the elongated through hole 11, and the length of the protrusion 21 is less than the length of the elongated through hole 11. The length of the elongated through hole 11 is 25-35mm longer than the length of the protrusion 21. This floating space can provide movement space for the skateboard when attaching and detaching the rod.

[0028] The upper surface of the protrusion 21 is also fixed with a retaining plate 3, the two sides of which abut against the slide plate 1. Preferably, the upper surface of the elongated through hole 11 forms a ring-shaped stepped surface with the upper surface of the slide plate 1, and the retaining plate 3 rests against this stepped surface. This structure makes the upper surface of the slide plate flatter, facilitating the installation of other structures.

[0029] The chain mounting bar 2 has a connecting hole A22 and a connecting hole B23 at both ends. The connecting hole A22 is fixed to the driving roller chain at the end of the drive sprocket, and the connecting hole B23 is fixed to the driving roller chain at the end of the driven sprocket.

[0030] Multiple sliding components are fixed to the bottom of the slide plate 1, allowing the slide plate 1 to slide and engage with the guide rail. Each sliding component includes an upper friction-reducing plate 41, a gasket 5, a lower friction-reducing plate 42, and a pressure plate 6, which are sequentially fixed by bolts. An elongated through-slot is formed between the upper and lower friction-reducing plates 41 and 42, and this through-slot engages with the guide rail. The upper and lower friction-reducing plates 41 and 42 are in direct contact with the upper and lower end faces of the guide rail, ensuring smooth and stable operation of the slide plate while minimizing mechanical wear and extending its service life.

[0031] A rotary actuator 8 is fixed to one end of the slide plate 1, and a hose fixing seat 7 is fixed to the other end. A rotary actuator positioning plate 12 is fixed to the slide plate 1. The rotary actuator positioning plate 12 has a groove. A rotary actuator positioning sleeve 81 is fixed to the bottom of the rotary actuator 8. The rotary actuator positioning sleeve 81 is embedded in the groove and fixed with bolts. A long strip-shaped hose guard plate 9 is also fixed to one side of the slide plate 1.

[0032] The working process of this utility model is as follows: During drilling, the rotary motor rotates forward, pushing the slide plate forward through the drive sprocket, the push roller chain, and one end of the chain mounting bar to contact the slide plate until a drill rod is driven to the bottom. When the rod is unloaded, the rotary motor reverses and lifts slightly, so that the other end of the chain mounting bar contacts the slide plate. At this time, there is a floating space of 25-35mm between one end of the chain mounting bar and the elongated through hole. Due to the existence of the floating space, the clamping cylinder tightens the drill rod by clamping the clamping block when the rod is clamped and the torsion bar is operated, so that the slide plate can move accordingly when the drill rod thread is loosened, without causing hard friction on the drill rod thread; the same applies to connecting the rod.

[0033] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
