Description

Technical Field

[0001] The utility model relates to the field of deep and large vertical shaft drilling method construction, in particular to a slurry discharge trough for a vertical shaft drilling machine. Background Art

[0002] In the current underground engineering, mining and other deep well operations, deep and large vertical shaft drilling rigs have been widely used for their efficient and stable drilling performance. Among them, the gas lift reverse circulation slag removal technology is an efficient slag removal method. It uses the rising force of the gas to bring the drill cuttings from the bottom of the borehole to the surface, ensuring the continuity and smoothness of the drilling process. During the gas lift reverse circulation slag removal process, the mud circulates through the drill pipe and the power head, and flows back to the mud pool through the pipeline, realizing the recycling of the mud.

[0003] During the construction of the shaft drilling rig, the main drive needs to be frequently raised and lowered to meet the drilling requirements of different depths. As a key component of mud circulation, the slurry discharge pipe is usually connected to the upper part of the drive unit through a flange to ensure its structural stability and easy disassembly and maintenance. The slurry discharge pipe adopts a steel pipe structure and is equipped with a swivel joint to enable it to rotate to meet the movement requirements of the drilling rig.

[0004] The lower part of the slurry discharge pipe reciprocates in the slurry discharge trough as the driving part rises and falls. The slurry discharge trough not only supports the slurry discharge pipe, but also guides the flow of mud to ensure that the mud can be discharged smoothly. In some deep well operations, due to the limitations of the topography and the working environment, slurry discharge troughs of different lengths and slopes are required. At the same time, due to the large amount of engineering and drilling operations, the amount of slurry discharge also increases. The slurry discharge troughs in the prior art are not strong enough and are prone to structural deformation, especially under long-term and high-load working conditions. Its stability is difficult to guarantee. Therefore, how to improve the adaptability of the slurry discharge trough in different working environments and improve its slurry discharge capacity and service life is a problem that needs to be urgently solved by technicians in this field. Utility Model Content

[0005] The utility model aims to provide a slurry discharge trough for a shaft drilling rig, which is composed of a plurality of trough bodies which are gradually elevated and present an inclined structural type, the trough bodies are butt-jointed by angle steels, and the bottom legs are connected to pre-buried anchor bolts by flange plates, thereby achieving the technical problem of improving the strength and stability of the slurry discharge trough.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design a slurry discharge trough for a vertical shaft drilling rig, comprising a trough body, a bracket, a support leg and a rail. The trough body is erected above the bracket, and the support leg is fixed under the bracket to support the bracket. The support leg is gradually raised so that the trough body has an inclined structure. The trough body is composed of multiple sections spliced ​​together, with the high side closed and the low side open. The rail is fixed at the bottom of the trough body, and a guide wheel is installed on the mud pipe to support the reciprocating motion of the mud pipe on the rail.

[0007] Furthermore, the multiple sections of the trough body are butt-jointed by angle steels, and the angle steels are connected by bolts to ensure sufficient strength and rigidity.

[0008] Furthermore, the edge of the trough body is reinforced by turning outwards with angle steel.

[0009] Furthermore, the rail is fixed to the bottom of the trough body through an upper pressing plate and a lower pressing plate.

[0010] Furthermore, the upper pressing plate and the lower pressing plate are connected by bolts.

[0011] Furthermore, the support leg is connected to the bracket by bolts, and a flange plate is provided at the lower part of the support leg, which is connected to the pre-buried anchor bolts to ensure that the slurry discharge trough will not shift.

[0012] Furthermore, the upper and lower connecting parts of the legs are both provided with reinforcing rib plates.

[0013] Furthermore, the legs at the lower part of the trough body on the lower side are single-leg structures, and the legs at the lower part of the other trough bodies are double-leg structures.

[0014] Furthermore, the legs are connected by angle steels.

[0015] Furthermore, the bracket and the channel body are correspondingly a multi-section structure, and the connecting end of the bracket is a channel steel, and the channel steel is provided with a through hole and connected by bolts.

[0016] Furthermore, the width of the bracket is wider than the width of the trough body, and operators can stand on the brackets on both sides of the trough body to clean slag.

[0017] Preferably, the trough body is a 4-section structure, and the bracket is a 4-section structure.

[0018] The advantages and beneficial effects of the utility model are:

[0019] 1. The utility model proposes a slurry discharge trough for a shaft drilling rig, which is provided with a trough body which is gradually elevated by multiple sections and presents an inclined structure, so as to achieve the adaptation of the length of the slurry discharge trough under different construction environments and requirements. The large slope design makes it difficult for mud and slag to be retained in the slurry discharge trough. The segmented design also makes hoisting more convenient and reduces construction costs. The width of the bracket is slightly wider than the trough body, which is convenient for personnel to carry out slag cleaning operations on the slurry discharge trough, thereby improving the work efficiency of personnel.

[0020] 2. Angle steel and reinforcing ribs are used to reinforce the connection between the various parts of the slurry discharge trough. The slurry discharge trough has high strength and is not prone to structural deformation. The support legs are highly stable, and the flanges at the bottom of the support legs can be directly connected to the anchor bolts. During use, the slurry discharge trough will not shift, thereby improving the stability and safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a slurry discharge trough for a shaft drilling rig includes a trough body 1, a bracket 2, a leg 3 and a rail 4. The trough body 1 is erected above the bracket 2, and a plurality of legs 3 are arranged below the bracket 2 to support the bracket 2. The legs 3 are gradually raised from front to back, so that the trough body 1 has an inclined structure, which is convenient for slag sliding and slurry discharge, and slag and stone retention is not likely to occur in the trough body 1. The rail 4 is arranged inside the trough body 1, and the guide wheel is installed on the mud pipe to meet the reciprocating motion of the mud pipe on the rail 4.

[0028] The trough body 1 is composed of four sections, with the high side closed and the low side open. The edges of the trough body 1 are reinforced by turning outward with angle steel. The trough body and the trough body sections are butt-jointed with angle steel and bolted to ensure the structural strength and rigidity of the entire trough body 1. The rail 4 is fixed to the bottom of the trough body 1 through the upper pressing plate 6 and the lower pressing plate 7, and the upper pressing plate 6 and the lower pressing plate 7 are bolted together.

[0029] The legs 3 are connected to the bracket 2 by bolts, and a flange plate 8 is provided at the bottom of the legs 3, which is connected to the pre-buried anchor bolts to ensure that the slurry discharge trough will not shift. The legs 3 at the front of the tank body 1 are single-leg structures, and the remaining legs 3 are double-leg structures, and gradually rise with the tank body 1. The legs 3 in the double-leg structure are connected to each other with angle steel, and the upper and lower flanges of the legs 3 are both provided with reinforcing ribs.

[0030] The bracket 2 follows the tank body 1 and is also a 4-section structure. The connecting ends of the brackets 2 and 2 are channel steels, which are provided with through holes and connected by bolts. The overall width of the bracket 2 is greater than the tank body 1. After installation, the operator can stand on the brackets 2 on both sides of the tank body to clean the slag.

[0031] Workflow: The operator selects a trough 1 of appropriate length according to the terrain of the working environment, hoists and installs the bracket 2 and the trough 1 respectively by a crane, and fixes the entire slurry discharge trough by connecting the flange plate under the leg 3 with the anchor bolts. Then, the rail 4 is fixed in the trough 1 by installing the upper pressing plate 6 and the lower pressing plate 7, and the guide wheel on the slurry discharge pipe is placed on the rail 4 to support the slurry discharge pipe and reciprocate in the slurry discharge trough. After the operation is completed, the operator can stand on the brackets 2 on both sides of the trough 1 to clean the residual mud in the trough 1.
