Description

Technical Field

[0001] This utility model relates to the field of vertical shaft wellbore casting technology, and more specifically, to a positioning casting device for vertical shaft wellbore. Background Technology

[0002] The shaft wall is the enclosure structure of the shaft, located inside the shaft, used to support and maintain the stability of the shaft, and also undertakes functions such as waterproofing and anti-collapse. For composite shaft walls, in order to ensure the quality of the shaft wall and to integrate the inner and outer walls into one, thereby improving the overall strength and waterproof performance of the shaft wall, grouting is required between the shaft walls after the inner wall is installed.

[0003] The existing method of grouting between well walls involves drilling holes in the inner well wall to install grouting pipes. The grouting pipes should pass through the inner well wall and enter the outer well wall. Therefore, during grouting, the grouting equipment needs to be positioned and connected with the grouting pipes. However, when performing grouting operations inside the well, a hoisting platform is usually used to suspend the equipment inside the well. The grouting equipment is placed on the hoisting platform, and the operator adjusts the position of the hoisting platform to control the positioning and connection of the grouting equipment with the grouting pipes on the well wall. This makes the operation extremely inconvenient. Furthermore, due to the gap between the hoisting platform and the well wall, the grouting pipeline may not be able to withstand the grout pressure during the grouting process, causing the grouting pipe opening to detach from the well wall grouting pipe, thus affecting the grouting efficiency.

[0004] Based on this, a positioning and casting device for vertical shaft well walls is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a positioning and casting device for vertical shaft well walls to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a positioning and grouting device for the wall of a vertical shaft, including a grouting machine. Support frames are fixedly installed on both sides of the middle of the front end of the outer surface of the grouting machine. Limiting grooves are opened through the middle of the adjacent sides of the outer surfaces of the support frames. A first adjusting screw is inserted and installed between the inner top surface and the inner bottom surface of the support frame through a bearing. A movable frame is movably installed on the adjacent sides of the outer surfaces of the support frame. Both ends of the movable frame are spirally sleeved on the outer surface of the first adjusting screw through the limiting grooves. A second adjusting screw is inserted and installed through the middle of the upper surface of the movable frame.

[0007] The movable frame is movably mounted with a scissor-type telescopic frame at its front end, and a fixed frame is movably mounted with the front end of the scissor-type telescopic frame. A connecting rod is fixedly mounted at the middle of the front end of the outer surface of the fixed frame.

[0008] A turntable is rotatably installed at the center of the front end of the grouting machine. A traction steel rope is wound around the outer surface of the turntable.

The other end of the traction steel rope passes through the inner and outer surfaces of the connecting rod and the sealing sleeve, which are interlaced and connected.

[0009] As a further improvement of this utility model, a door is installed at the middle of the rear end of the outer surface of the grouting machine via a hinge. A connecting shaft is fixedly installed at the middle of the front end of the outer surface of the grouting machine. A slurry storage frame is fixedly installed at the middle of the inner surface of the grouting machine. A mud conveying pump assembly is fixedly installed on the inner bottom surface of the grouting machine. The mud conveying pump assembly includes a hopper. A conveying motor is fixedly installed at the rear end of the outer surface of the hopper. A discharge pipe is fixedly installed at the front end of the outer surface of the hopper. A conveying screw is movably installed inside the discharge pipe. The output end of the conveying motor is fixedly connected to one end of the conveying screw. The hopper is connected to the middle of the inner bottom surface of the slurry storage frame. The other end of the discharge pipe extends outward through the grouting machine.

[0010] As a further improvement of this utility model, a mixer is fixedly installed through the middle of the upper surface of the grouting machine, and a feed port is opened through the middle of the rear end of the outer surface of the mixer. A stirring blade is rotatably installed in the middle of the inner top surface of the mixer.

[0024] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0025] Please see Figures 1-4 As shown, a positioning and grouting device for a vertical shaft well wall includes a grouting machine 1. A door 101 is hinged to the middle of the rear end of the outer surface of the grouting machine 1. A connecting shaft 102 is fixedly protruding from the middle of the front end of the outer surface of the grouting machine 1. A slurry storage frame 103 is fixedly installed in the middle of the inner surface of the grouting machine 1. A mud conveying pump assembly 104 is fixedly installed on the inner bottom surface of the grouting machine 1. The mud conveying pump assembly 104 includes a hopper. A conveying motor is fixedly installed at the rear end of the outer surface of the hopper. A discharge pipe is fixedly installed at the front end of the outer surface of the hopper. A conveying screw is movably installed inside the discharge pipe. The output end of the conveying motor is fixedly connected to one end of the conveying screw. The hopper is connected to the middle of the inner bottom surface of the slurry storage frame 103. The other end of the discharge pipe extends outward through the grouting machine 1.

[0026] A mixer 2 is fixedly installed through the middle of the upper surface of the grouting machine 1. A feed inlet 201 is opened through the middle of the rear end of the outer surface of the mixer 2. A stirring blade 202 is rotatably installed in the middle of the inner top surface of the mixer 2. A motor 203 is fixedly installed on the upper surface of the mixer 2. The output end of the motor 203 is fixedly connected to the upper surface of the stirring blade 202. A discharge port 204 is opened through the middle of the lower surface of the mixer 2. An insertion port is opened at the rear end of the outer surface of the discharge port 204. A sealing plate 205 is movably installed in the discharge port 204 through the inner surface of the insertion port.

[0027] It should be noted that the grouting material is added through the feed inlet 201. After the addition is completed, the stirring blade 202 is controlled by the motor 203 to stir and mix the grouting material in the mixer 2. After the mixing is completed, the sealing plate 205 is pulled to open the discharge port 204 to discharge the grout into the grout storage frame 103. At this time, the mud conveying pump assembly 104 is started to discharge the grout into the telescopic pipe 6 for grouting operation.

[0028] Support frames 3 are fixedly installed on both sides of the middle of the front end of the outer surface of the grouting machine 1. Limiting grooves are opened through the middle of the side of the outer surface of the support frame 3 that are close to each other. The inner top surface and inner bottom surface of the support frame 3 are connected by bearings and a first adjusting screw 301 is inserted and installed. The side of the outer surface of the support frame 3 that are close to each other is movably installed with a movable frame 302. Both ends of the movable frame 302 are spirally sleeved on the outer surface of the first adjusting screw 301 through the limiting groove. The upper surface of the movable frame 302 is limited and inserted through the middle of the middle.

[0029] The front end of the movable frame 302 is movably mounted with a scissor-type telescopic frame 4. Both ends of the scissor-type telescopic frame 4 are movably hinged with connecting ears 401. The connecting ears 401 at the rear end are respectively spirally movably sleeved on both ends of the outer surface of the second adjusting screw 303. The front end of the scissor-type telescopic frame 4 is movably mounted with a fixed frame 402. A fixed rod is fixedly installed between the middle of the inner top surface and the inner bottom surface of the fixed frame 402. The connecting ears 401 at the front end are respectively movably sleeved on both ends of the outer surface of the fixed rod. A connecting rod 403 is fixedly installed at the middle of the front end of the outer surface of the fixed frame 402.

[0030] It should be noted that by controlling the clockwise and counterclockwise rotation of the first adjusting screw 301, the movable frame 302 can be controlled to move longitudinally up and down along the limiting groove. Since the second adjusting screw 303 is a bidirectional screw structure, by controlling the clockwise and counterclockwise rotation of the second adjusting screw 303, the connecting ears 401 can be controlled to move together and apart. Thus, the opening and closing of the connecting ears 401 can be used to control the opening and closing of the scissor telescopic frame 4. The opening and closing of the scissor telescopic frame 4 can control the lateral forward and backward movement of the fixed frame 402. The longitudinal lifting and lowering movement of the movable frame 302 combined with the lateral forward and backward movement of the fixed frame 402 achieves the effect of multi-directional adjustment of the control link 403.

[0031] A turntable 5 is rotatably installed at the middle of the front end of the grouting machine 1. The turntable 5 is rotatably sleeved on the outer surface of the connecting shaft 102. A traction steel rope 501 is wound around the outer surface of the turntable 5. A telescopic pipe 6 is fixedly installed at the lower front end of the grouting machine 1. The rear end of the telescopic pipe 6 is connected to the end of the discharge pipe that extends outward through the grouting machine 1. An adapter 601 is fixedly installed at the front end of the outer surface of the telescopic pipe 6. The other end of the connecting rod 403 is movably sleeved on the outer surface of the adapter 601. A sealing sleeve 602 is fixedly installed at the front end of the outer surface of the adapter 601. The other end of the traction steel rope 501 passes through the inner and outer surfaces of the connecting rod 403 and the sealing sleeve 602 and is interlaced with each other. A limit buckle 502 is fixedly installed at the other end of the traction steel rope 501. The limit buckle 502 is movably sleeved on the outer surface of the traction steel rope 501.

[0032] It should be noted that the multi-directional adjustment of the connecting rod 403 can control the expansion of the telescopic pipe 6, thereby controlling the adapter 601 at the end of the telescopic pipe 6 to connect with the grouting pipe on the well wall. The connecting rod 403 can also support the telescopic pipe 6, preventing it from detaching from the grouting pipe due to insufficient grout pressure. Since the diameter of the adapter 601 is larger than that of the grouting pipe, the adapter 601 can wrap around the grouting pipe. After the adapter 601 is connected with the grouting pipe, the turntable 5 can be rotated clockwise to control the winding and retraction of the traction steel rope 501. Since the traction steel rope 501 passes through the connecting rod 403, the point where the connecting rod 403 passes through can be used as a support point. At this time, the retraction of the traction steel rope 501 can control the sealing sleeve 602 to close and fit with the grouting pipe to achieve a sealing effect, ensuring that the grout transported by the telescopic pipe 6 can stably enter the grouting pipe to complete the grouting operation.

[0033] In use, the position of the grouting machine 1 on the hanging platform can be adjusted so that the grouting machine 1 is parallel to the grouting pipe set on the well wall. At this time, according to the position difference between the grouting pipe and the telescopic pipe 6, the first adjusting screw 301 is controlled to rotate clockwise and counterclockwise, thereby controlling the movable frame 302 to move longitudinally up and down along the limiting groove until the port of the telescopic pipe 6 is parallel to the grouting pipe. At this time, the second adjusting screw 303 can be controlled to rotate clockwise and counterclockwise to control the connecting ears 401 to move together and open. The opening and closing of the connecting ears 401 controls the opening and closing of the scissor telescopic frame 4. The opening and closing of the scissor telescopic frame 4 controls the fixed frame 402 to move laterally back and forth. The lateral back and forth movement of the fixed frame 402, with the help of the connecting rod 403, controls the port of the telescopic pipe 6 to connect with the grouting pipe.

[0034] After the adapter 601 is connected to the grouting pipe, the turntable 5 can be rotated clockwise to control the traction steel rope 501 to wind and shrink. The shrinkage of the traction steel rope 501 can stretch the sealing sleeve 602, control the sealing sleeve 602 to close and fit with the grouting pipe to achieve a sealing effect. At this time, the slurry can be generated by the mixer 2, and the mixed slurry can be transported to the telescopic pipe 6 through the mud conveying pump assembly 104 to be introduced into the grouting pipe to complete the grouting operation.

[0035] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
