Description

Technical Field

[0001] The invention relates to the technical field of slurry lifting buckets, and in particular to a slurry lifting bucket suitable for cable holes and ventilation shafts. Background Art

[0002] During the construction of cable holes and ventilation shafts, a drilling rig is required to carry out large-diameter drilling construction. During the construction process, sediment and drill cuttings will be produced at the bottom of the hole. In order to ensure the cleanliness of the bottom of the hole, thereby ensuring the quality of the drilling and the effect of subsequent concrete pouring, grouting work is often required.

[0003] At present, traditional pumping methods often leave a lot of slurry at the bottom of the hole and in the pump pipe, which poses a great safety hazard to the subsequent underground pipeline connection. The remaining slurry may cause the slurry inlet hole to be connected with the water inrush point, causing a water inrush accident. The remaining slurry may also cause slurry cross-linking between the slurry inlet holes, affecting the grouting effect and the safety of the mine.

[0004] Therefore, in view of the above-mentioned existing pumping methods, a large amount of slurry often remains at the bottom of the hole and in the pump pipe, causing water inrush accidents or slurry mixing between the slurry inlet holes, and it is necessary to design a new type of slurry lifting bucket. Summary of the invention

[0005] The purpose of the present invention is to provide a slurry lifting bucket suitable for cable holes and ventilation wells, which has a simple structure, is easy to operate and has high slurry lifting efficiency. By adding counterweights in the bucket, the slurry inlet hole is opened and closed by opening a valve steel plate in conjunction with gravity, thereby transferring the slurry from the hole, reducing the residual slurry in the hole, and reducing safety hazards.

[0006] In order to solve the above technical problems, the present invention provides a slurry lifting bucket suitable for cable holes and ventilation shafts, comprising:

[0007] The present invention provides a slurry lifting bucket suitable for cable holes and ventilation shafts, comprising:

[0008] A pulp lifting barrel body, wherein a pulp inlet is provided at the bottom of the pulp lifting barrel body, and a support plate is provided at a position close to the inner bottom of the pulp lifting barrel body, and a pulp inlet hole is provided on the support plate;

[0009] A switch assembly, comprising a counterweight pressure valve; the counterweight pressure valve is located in the pulp lifting barrel body and directly above the support plate, a support rod is provided at the bottom of the counterweight pressure valve, the support rod passes through the support plate and the pulp inlet and extends to the outside of the pulp lifting barrel body, an opening valve assembly is provided at the bottom of the support rod, and the projection of the counterweight pressure valve in the vertical direction covers the pulp inlet hole;

[0010] When the main body of the slurry lifting bucket is placed at the bottom of the hole, the split valve assembly at the bottom of the hole generates thrust, and the support rod moves upward in the hole groove, driving the counterweight pressure valve to move upward, exposing the grouting hole, allowing the slurry in the hole to enter the main body of the slurry lifting bucket. When the main body of the slurry lifting bucket is moved upward, the counterweight pressure valve falls due to the influence of gravity and presses down the slurry inlet hole to prevent the slurry from seeping out, thereby realizing the transfer of the residual slurry inside and reducing safety hazards.

[0011] Preferably, a movable hole is provided at the center of the support plate;

[0012] The support rod passes through the movable hole.

[0013] Preferably, the support rod is provided with an external thread;

[0014] The movable hole is provided with an internal thread;

[0015] The support rod is threadedly engaged with the movable hole;

[0016] The height of the counterweight pressure valve and the valve opening assembly can be changed by moving the support rod up and down in the movable hole.

[0017] Preferably, the number of the pulp inlet holes is four;

[0018] The four pulp inlet holes are arranged in a ring shape.

[0019] Preferably, the four pulp inlet holes are evenly arranged around the center of the support plate;

[0020] The valve opening assembly is located between the four slurry inlet holes;

[0021] Under natural conditions, the valve opening assembly is located at the bottom of the slurry lifting barrel due to gravity. When the slurry lifting barrel moves to the bottom of the hole, the bottom of the hole will squeeze the valve opening assembly. Since the valve opening assembly is movable, it will move upward to push the counterweight pressure valve open, making it convenient for the slurry in the hole to enter the top of the support plate along the slurry inlet hole.

[0022] Preferably, a rubber foot pad is provided at the bottom of the counterweight pressure valve; the bottom end of the rubber foot pad is tightly attached to the top of the supporting steel plate; the rubber foot pad has good sealing performance, and when it blocks the slurry inlet hole, it can enable the supporting plate and the slurry lifting barrel body to form a closed container for filling slurry for transfer.

[0023] Preferably, two columns are stacked on the left and right sides of the top of the pulp lifting barrel body;

[0024] The column is connected with a universal shaft lifting ring assembly;

[0025] The lifting ring of the universal shaft can be rotated. When in use, it can be rotated to be perpendicular to the main body of the pulp lifting barrel to facilitate the up and down movement of the device therein. When not in use, it can be rotated to a horizontal position to reduce the height and the transportation space.

[0026] Preferably, the universal shaft lifting ring assembly comprises a lifting ring body and two rotating shafts;

[0027] The two rotating shafts are fixedly connected to the outer sides of the two columns respectively;

[0028] The two ends of the lifting ring body are respectively hinged to two rotating shafts;

[0029] The universal shaft lifting ring is equipped with a steel wire rope connected to the lifting device. The lifting bucket tool is fixed to the device through the steel wire rope and the lifting ring body, and the lifting bucket is driven up and down in the hole by the lifting device. The rotating shaft is fixed to the column and cannot rotate, while the lifting ring body can rotate around the rotating shaft to change the angle of the lifting ring body.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By designing a slurry lifting bucket suitable for cable holes and ventilation wells, when the main body of the slurry lifting bucket is placed at the bottom of the hole, the valve assembly at the bottom of the hole generates thrust, and the support rod moves upward in the movable hole, driving the counterweight pressure valve to move upward, exposing the grouting hole, so that the slurry in the hole enters the casing. When the main body of the slurry lifting bucket is moved upward, the counterweight pressure valve falls due to the influence of gravity, and the rubber foot pad presses the slurry inlet hole to prevent the slurry from seeping out, thereby realizing the transfer of the residual slurry inside and reducing safety hazards;

[0032] 2. The slurry lifting bucket has a simple process, is easy to manufacture and maintain, can be applied in many scenarios, and is easy to operate without complex training. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The two rotating shafts 10 are fixedly connected to the outer sides of the two columns 8 respectively;

[0063] The two ends of the lifting ring body 9 are respectively hinged to two rotating shafts 10 .

[0064] In order to better illustrate the technical effect of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0065] Embodiment 1: A slurry lifting bucket suitable for cable holes and ventilation shafts, such as Figure 1 As shown, it includes a pulp lifting barrel body 1, a support plate 2, a pulp inlet hole 3, a counterweight pressure valve 4, a support rod 5 and a valve opening assembly 6;

[0066] The main body 1 of the slurry lifting bucket is a casing, and a support plate 2 is fixedly connected inside the main body 1 of the slurry lifting bucket. A slurry inlet hole 3 penetrating the support plate 2 is provided on the support plate 2. A counterweight pressure valve 4 is provided on the support plate 2. A support rod 5 penetrating the support plate 2 is connected to the bottom of the counterweight pressure valve 4. A valve opening assembly 6 is fixedly connected to the bottom of the support rod 5. When the main body 1 of the slurry lifting bucket is placed at the bottom of the hole, the bottom of the hole generates thrust to the valve opening assembly 6, and the support rod 5 moves upward in the hole groove, driving the counterweight pressure valve 4 to move upward, exposing the grouting hole, so that the slurry in the hole enters the main body 1 of the slurry lifting bucket. When the main body 1 of the slurry lifting bucket is moved upward, the counterweight pressure valve falls due to the influence of gravity, and the rubber foot pad 7 presses the slurry inlet hole 3 to prevent the slurry from leaking out, thereby realizing the transfer of the residual slurry inside and reducing safety hazards.

[0067] like Figure 2-Figure 3 As shown, in this embodiment, a rubber foot pad 7 is fixedly connected to the bottom end of the counterweight pressure valve 4, and the bottom end of the rubber foot pad 7 is tightly attached to the top end of the support plate 2. A movable hole 21 is provided in the middle of the support plate 2, and the support rod 5 is screwed into the movable hole 21. The four pulp inlet holes 3 provided on the support plate 2 are arranged in a ring shape, and the valve opening assembly 6 located below the support plate 2 is arranged at the bottom end of the pulp lifting barrel body 1. The valve opening assembly 6 is located between the four pulp inlet holes 3. The rubber foot pad 7 has good sealing performance. When it blocks the pulp inlet hole 3, it can make The support plate 2 and the sleeve form a closed container for filling slurry for transfer. The height of the counterweight pressure valve and the valve opening assembly 6 is changed by the support rod 5 spirally moving up and down in the movable hole 21. In a natural state, the valve opening assembly 6 is located at the bottom of the slurry lifting barrel body 1 due to gravity. When the slurry lifting barrel body 1 moves to the bottom of the hole, the bottom of the hole will squeeze the valve opening assembly 6. Since the valve opening assembly 6 is movable, it will move upward to push open the counterweight pressure valve 4, making it convenient for the slurry in the hole to enter the support plate 2 along the slurry inlet hole 3.

[0068] like Figure 4-Figure 6As shown, in this embodiment, the top of the pulp lifting bucket body 1 is fixedly connected with left and right opposite columns 8, and the top of the pulp lifting bucket body 1 is provided with a universal shaft lifting ring movably connected to the column 8. The universal shaft lifting ring is composed of a lifting ring body 9 and a rotating shaft 10. A wire rope connected to the lifting device is installed on the universal shaft lifting ring. The opposite side of the column 8 is fixedly connected with the rotating shaft 10, and the lifting ring body 9 is movably sleeved on the outside of the rotating shaft 10. It can be rotated through the universal shaft lifting ring. When in use, it is rotated to be vertical to the pulp lifting bucket body 1, which is convenient for the device therein to move up and down. When it is not in use, it can be rotated to a horizontal level, reducing the height and reducing the transportation space. The pulp lifting bucket tool is fixed to the device therein through the wire rope and the lifting ring body 9, and the pulp lifting bucket is driven to move up and down in the hole by the lifting device. A shaft sleeve matching the rotating shaft 10 is provided on the lifting ring body 9. The rotating shaft 10 is fixedly connected to the column 8 and cannot rotate, while the lifting ring body 9 can rotate around the rotating shaft 10, thereby changing the angle of the lifting ring body 9.

[0069] When working, first select a suitable slurry lifting bucket body 1 according to the hole diameter to make the slurry lifting bucket. Before use, pull out the construction drilling rig wire rope, replace the wire rope with the same length as the installation hole depth, and the wire rope diameter is calculated according to the drilling hole depth and the net weight of the slurry lifting bucket. Rotate the lifting ring body 9 to make it rotate along the rotating shaft 10 to a state perpendicular to the slurry lifting bucket body 1, and then install the front end of the wire rope on the lifting ring;

[0070] The slurry lifting bucket is lowered to the bottom of the hole. The support at the bottom of the hole will exert force on the movable connection development steel plate to move the valve opening assembly 6 upward, driving the support rod 5 to move upward to lift the counterweight pressure valve 4, allowing the slurry in the hole to flow from the slurry inlet hole 3 to the slurry lifting bucket. Then the slurry lifting bucket is lifted up. Under the influence of gravity, the counterweight pressure valve 4 will press the rubber foot pad 7 against the slurry inlet hole 3 to prevent the slurry in the slurry lifting bucket from seeping out. After lifting the slurry lifting bucket out of the wellhead, place it in the mud tank. The valve opening assembly 6 is forced to open the rubber foot pad 7 and the counterweight pressure valve 4, allowing the slurry to flow out of the slurry lifting bucket smoothly. The reciprocating cycle is repeated until the remaining slurry in the hole is extracted as much as possible to reduce safety hazards.

[0071] Through the above steps, when the slurry lifting bucket body 1 is placed at the bottom of the hole, the split valve assembly 6 at the bottom of the hole generates thrust, and the support rod 5 moves upward in the movable hole 21, driving the counterweight pressure valve 4 to move upward, exposing the grouting hole, so that the slurry in the hole enters the slurry lifting bucket body 1. When the slurry lifting bucket body 1 is moved upward, the counterweight pressure valve 4 falls due to the influence of gravity, and the rubber foot pad 7 presses the slurry inlet hole 3 to prevent the slurry from seeping out, thereby realizing the transfer of the residual slurry inside and reducing safety hazards, so as to solve the problem that the existing pumping method often leaves a lot of slurry at the bottom of the hole and in the pump pipe, which poses a great safety hazard to the later downhole pipeline connection.

[0072] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
