Description

Technical Field

[0001] The utility model relates to the technical field of ore and rock mining, in particular to a hydraulic fracturing sealer conveying device. Background Art

[0002] Hydraulic fracturing is a common method used in traditional rock mining. It creates fractures by injecting high-pressure fluid into rock, thereby breaking it up and increasing resource recovery. Delivering the drill pipe and sealer to the desired depth is a critical step in hydraulic fracturing operations.

[0003] Traditional hydraulic fracturing drill pipe delivery systems typically use hydraulic or electric drive systems to deliver and retrieve the drill pipe. However, these traditional systems have some significant disadvantages:

[0004] The first is power dependence. Traditional conveying devices rely on external power supplies or hydraulic systems for power, which limits their use in remote mining areas where there is no power or hydraulic source.

[0005] The second is high maintenance costs. Hydraulic and electric systems usually require regular maintenance and are susceptible to harsh environments, resulting in increased failure rates and higher maintenance costs.

[0006] Furthermore, in special environments such as high humidity and highly corrosive gases, the electronic and hydraulic components of traditional systems are easily damaged. Operating in mining areas requires operators to possess certain technical knowledge to control and maintain these complex systems, increasing training costs and operational difficulty. This can hinder the efficient and effective delivery and retrieval of drill rods, impacting operational efficiency and safety. Utility Model Content

[0007] The technical problem to be solved by the utility model is how to provide a hydraulic fracturing sealer conveying device which is easy to operate and maintain.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] A hydraulic fracturing sealer conveying device comprises a frame, a fixed shaft is transversely fixed to the top of the frame, a rotating shaft is transversely provided on one side below the fixed shaft, and both ends of the rotating shaft are movably connected to the frame;

[0010] A steel wire rope is wound around the rotating shaft, and the other end of the steel wire rope is passed around a second bearing arranged in the middle of the fixed shaft and connected to a sleeve. A rocker is installed on the rotating shaft, and a limiting component for fixing the rocker is also provided on the frame.

[0011] This application arranges a steel wire rope to bypass a fixed shaft connecting sleeve, and drives the steel wire rope to be wound by rotating a manual rocker, so that the sleeve drives the sealer to be transported. The device relies on the bearing to transmit torque in the middle, and does not need to rely on an external power supply or hydraulic system, which greatly reduces the dependence on external conditions and maintenance costs. In addition, the device is simple to operate, convenient for emergency response, and has strong environmental adaptability. It can work stably under various harsh conditions, thereby improving the efficiency and safety of mineral mining.

[0012] As a further solution of the present invention: the rotating shaft is located at an obliquely rear position of the fixed shaft.

[0013] As a further solution of the present invention: a wire rope clamp for fixing the wire rope is installed on the rotating shaft.

[0014] As a further solution of the present invention: the limiting assembly includes a latch, wherein the latch is in a "T"-shaped structure, and one end of the latch can be detachably mounted on the frame.

[0015] As a further solution of the present invention: a plurality of circular fixing holes are installed on the frame, wherein support legs are installed on the circular fixing holes, and the bottoms of the support legs are supported to the ground.

[0016] As a further solution of the present invention: the fixed shaft is arranged parallel to the rotating shaft.

[0017] As a further solution of the present invention: both ends of the rotating shaft are connected to a first bearing, wherein the first bearing is fixed to the frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] First, the present application arranges a steel wire rope to pass around a fixed shaft to connect the sleeve, and drives the steel wire rope to be wound by rotating the manual rocker, so that the sleeve drives the hole sealer to be transported. The device relies on the bearing to transmit torque in the middle, and does not need to rely on an external power supply or hydraulic system, which greatly reduces the dependence on external conditions and maintenance costs. In addition, the device is simple to operate, convenient for emergency response, and has strong environmental adaptability. It can work stably under various harsh conditions, thereby improving the efficiency and safety of rock mining.

[0020] Secondly, this application sets a pin, which is installed in a "T" shape on the frame. It can limit the rocker. When the sleeve drives the hollow steel pipe to the desired position, the pin can be used to limit the rocker to fix the position of the hollow steel pipe. No manual assistance is required, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] Reference Figure 1 A hydraulic fracturing sealer conveying device includes a frame 1, a rocker 2, a rotating shaft 3, a wire rope clamp 4, a latch 5, a circular fixing hole 6, a supporting leg 7, a fixed shaft 8, a wire rope 9, a sleeve 10, a first bearing 11 and a second bearing 12;

[0033] The frame 1 is used to support the entire sealer conveying device, which includes two rectangular vertical frames, which are fixedly connected by a connecting rod at the rear end between the two vertical frames. From a top view, it can be seen that the frame 1 is in a "U" shape as a whole. A fixed shaft 8 is horizontally installed at the middle position of the top of the two vertical frames, and a rotating shaft 3 is horizontally installed at the lower position of the two vertical frames. The fixed shaft 8 is arranged parallel to the rotating shaft 3, and the rotating shaft 3 is located obliquely behind the fixed shaft 8. The two are not on the same vertical line.

[0034] For ease of understanding and description, Figure 1 The front and rear marks in the figure are the front and rear directions of the present application. It should be understood that this direction setting is only for the convenience of description and understanding and cannot be understood as a limitation of the present invention.

[0035] Reference Figure 1 and Figure 2 , both ends of the rotating shaft 3 are connected to the first bearing 11, and the two first bearings 11 are respectively fixed to the two vertical frames. One end of the rotating shaft 3 is fixedly connected to the rocker 2 by a bolt or a pin. By rotating the rocker 2, the rotating shaft 3 can be driven to rotate between the two first bearings 11;

[0036] Further, refer to Figure 3 A steel wire rope 9 is wound around the rotating shaft 3. The steel wire rope has good flexibility, high strength and corrosion resistance, and can adapt well to the environment in the mine. One end of the steel wire rope 9 is fixed to the rotating shaft 3 through a steel wire rope clamp 4. The steel wire rope clamp 4 adopts a galvanized steel wire rope clamp. The galvanized steel wire rope clamp, also known as a steel wire rope clip, is mainly used for temporary connection of various steel wire ropes, including galvanized steel wire rope, phosphate-coated steel wire rope, stainless steel wire rope and smooth steel wire rope, and for fixing the rear hand rope.

[0037] The wire rope chuck 4 includes a chuck with a "U"-shaped structure, in which a clamping block is threadedly connected to the "U"-shaped chuck, and one end of the wire rope 9 is fixed to the rotating shaft 3 through the clamping block, thereby limiting the end of the wire rope 9; when the rocker 2 drives the rotating shaft 3 to rotate, it can also drive the wire rope 9 to wind along the rotating shaft 3, and then pull the sleeve 10 to move through the wire rope 9.

[0038] Reference Figure 1 and Figure 6 , a group of latches 5 are provided, which are installed at one end of the rocker 2. The latches 5 can be fixed to the frame 1 by means of bolt pins, etc. The latches 5 are used to limit the rotation of the handle rocker 2. When the rocker 2 is shaken until the hollow steel tube 15 is lifted to the desired height, the latch is inserted to release the rocker 2. The rocker 2 rotates a short distance, and then stops rotating due to the limit of the latch 5, and the rope 9 does not move, and the entire device is stationary (refer to Figure 6 ).

[0039] Reference Figure 1 The support legs 7 (there are four in this device) are shaped like a crutch, and the short end thereof is inserted into the circular hole 6 opened on the frame 1. The circular hole 6 is provided in several groups, and the connection is connected with bolts and nuts. The support legs 7 can be used to resist the reaction force of the hollow steel pipe 15 connected to the sleeve 10 to release high-pressure water, thereby preventing the entire device from tilting and collapsing.

[0040] Reference Figure 1 The fixed shaft 8 is fixed to the top of the frame 1 horizontally and can be fixed by welding to ensure stability. The fixed shaft 8 is installed in the middle position of the top of the frame 1 as much as possible. A second bearing 12 is installed in the middle position of the fixed shaft 8. The circumferential direction of the second bearing 12 is concave to facilitate the winding of the wire rope 9 (refer to Figure 4 The end of the steel wire rope 9 is wrapped around the sleeve 10 and the middle is passed around the second bearing 12. The sleeve 10 is used to place the hollow steel pipe 15. There is a buckle on the side of the sleeve 10. The steel wire rope can be tied to the sleeve 10 by wrapping around the buckle (refer to Figure 5 ).

[0041] The specific operating principles of this application are as follows:

[0042] The connector 13 of the present application is annular, one end of which is connected to the anchor rod by a thread, and the anchor rod is fixed to the tunnel roof. The ring on the connector 13 can be connected to the ring of the positioning clamp 14 through a soft connection such as a chain or a steel rope. The positioning clamp 14 is an integral cylindrical structure with a vertical groove and a threaded hole on the top for positioning the hollow steel pipe 15.

[0043] It should be noted that the hollow steel pipe 15 is a special hydraulic fracturing hollow steel pipe, which is different from the traditional drill pipe. It is hollow inside, about 1.5m long, 25mm in diameter, with a male end and a female end. The diameter of the connection between the two ends is about 36mm, and it weighs about 2.5kg. Two hollow steel pipes 15 can be connected end to end.

[0044] By using the connector 13, the positioning fixture 14 can be suspended below the tunnel roof. The positioning fixture 14 can provide a support point for the hollow steel pipe 15, so that the hollow steel pipe 15 and the tunnel top drill hole, the positioning fixture 14 and the sleeve 10 have three support points; the positioning fixture 14 can be screwed with a screw through the reserved threaded port to fix the hollow steel pipe 15 passing through the positioning fixture 14. By tightening the screw to fix the hollow steel pipe 15, the hollow steel pipe 15 can be prevented from slipping when connecting the next section of the hollow steel pipe 15; after the next section of the hollow steel pipe 15 to be transported is threadedly connected to the tail end of the hollow steel pipe 15 fixed by the screw on the positioning fixture 14, the screw is loosened to transport the hollow steel pipe 15. By the above reciprocating transportation of the hollow steel pipe 15, the sealer is transported to the fracturing position.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
