Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a grouting device for the treatment of geological disasters in mines. Background Technology

[0002] Mineral resource extraction is the largest organized human activity to date that has altered the Earth's surface landscape and destroyed its ecosystems. After mining, large amounts of waste tailings and exposed rocks are left behind, making it difficult for plants to survive. If timely ecological restoration is not achieved, it may trigger a series of ecological and environmental problems, and in more serious cases, it may cause geological disasters, endangering the safety of nearby residents or construction workers. Geological disaster management is generally carried out through grouting, and this device is needed in such cases.

[0003] Currently, existing grouting devices are used to mix mud and sand in the field and inject it in real time. However, the uneven ground in the field causes the mud and sand to tilt to one side during mixing, resulting in uneven mixing.

[0004] A search revealed a Chinese patent (publication number: CN218150938U) that discloses a grouting device for mine geological disaster control. When unevenness is detected, the device utilizes the combined action of a threaded rod and a hand crank. Manually rotating the hand crank causes the threaded rod to rotate, moving it up and down within the connecting block to adjust its height. After adjusting the four corners and confirming levelness with reference to the connecting column and balancer, a limiting rod is inserted into the second limiting hole. The combined action of the first and second limiting holes and the limiting rod secures the circular block or plate, preventing the threaded rod's rotation from affecting balance. After securing, the block is inserted into the ground for further fixation. Finally, the feed inlet is opened to pour mud and sand into the mixing tank. The rotating motor is started, driving the shaft and the mixing rod to stir the mud and sand. After thorough mixing, the valve is opened, and the stirred mud and sand are discharged through the outlet pipe into the designated location.

[0005] Because there is a lot of gravel on the mine surface and the soil below is hard, when the hand crank drives the block to rotate and move it underground, the block can only enter the gravel on the surface. When the above-mentioned device drives the stirring rod to stir the mud and sand in the mixing box through the motor, it will generate a pushing force along the axis of the mixing box, causing the device to move. This results in poor fixation and thus the stability needs to be improved, which is not conducive to stirring mud and sand. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a grouting device for the management of geological disasters in mines, which solves the problems mentioned in the background section.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 The present invention relates to a grouting device for the treatment of geological disasters in mines, comprising a base plate 1, and a grouting and mixing device 2 installed on the top of the base plate 1.

[0022] The grouting and mixing equipment 2 includes a mixing drum, which is installed on the base plate 1. The mixing drum is hollow inside and has a feed hopper installed on the top for injecting mud and sand materials into the mixing drum. A second motor is installed on the top of the mixing drum, and a rotating rod placed in the mixing drum is installed on the rotating end of the second motor. Multiple mixing rods are installed on the rotating rod. After mud, sand materials and water are injected into the mixing drum along the feed hopper, the second motor drives the mixing rods to mix the materials in the mixing drum.

[0023] A conveying cylinder is fixedly connected to the bottom wall of the mixing drum. The top wall of the conveying cylinder, which is located inside the mixing drum, has a feed inlet and is connected to the inside of the mixing drum. An auger is installed in the conveying cylinder. A first motor connected to the auger is installed at one end of the conveying cylinder, and a grouting pipe is installed at the other end. A grouting head is installed at the end of the grouting pipe. The first motor drives the auger to convey the sand and gravel material in the mixing drum into the grouting pipe, and personnel hold the grouting head to grout the mine.

[0024] Multiple evenly distributed internally threaded tubes 3 are fixedly connected to the top edge of the base plate 1, and the internally threaded tubes 3 are connected to the bottom of the base plate 1. In this application, the number of internally threaded tubes 3 is one. A plug assembly 4 is installed on the internally threaded tube 3. The plug assembly 4 includes a threaded rod 7. The threaded rod 7 extends into the internally threaded tube 3 and is threadedly connected. A connecting plate 9 is installed at the top of the threaded rod 7, and a conical head 8 is fixedly connected to the bottom. A crank 10 is connected to the top of the connecting plate 9.

[0025] Turn the crank handle 10 to make the threaded rod 7 rotate on the internal threaded tube 3, and adjust the length of the conical head 8 extending below the base plate 1.

[0026] Multiple sliding rods 5 are fixedly connected to the top of the base plate 1. In this application, there are two sliding rods 5, which are inverted T-shaped. A ramming block 6 is fitted on the upper sliding rod 5 and is slidably connected. A connecting plate 12 is connected between the two ramming blocks 6, and a handle 11 is installed on the ramming block 6.

[0027] Hold the handle 11 and lift the ramming block 6 upward along the slide bar 5. Then release the handle 11. Under its own weight, the ramming block 6 strikes the slide bar 5 and pushes the insertion rod assembly 4 into the ground, thus fixing the base plate 1.

[0028] The upper side wall of the base plate 1 has multiple bubble level gauges 13. In this application, two bubble level gauges are provided, and the two bubble level gauges 13 are respectively installed on the adjacent side wall of the base plate 1 to determine the horizontal state of the base plate 1 after it is fixed.

[0029] In summary, when using this grouting device for mine geological disaster control, move the device to the location in the mine where grouting is needed, hold the crank handle 10 and rotate the threaded rod 7 on the internal threaded pipe 3 to create a distance between the conical head 8 and the base plate 1, thus providing support for the base plate 1 on the ground. Then observe the bubble level 13 to determine whether the base plate 1 is level. If the base plate 1 is not level, continue to rotate the crank handle 10 until the base plate 1 is level.

[0030] Once the base plate 1 is level, two people hold handles 11 and lift the ramming block 6 upwards along the slide bar 5. Then they release their hands, and the ramming block 6, under its own weight, strikes the slide bar 5 and exerts a downward impact force on the conical head 8 through the base plate 1, causing the conical head 8 and the threaded rod 7 to insert into the ground. After repeated operations, the ramming block 6 makes the base plate 1 contact the ground.

[0031] Then observe the bubble level 13 to determine if the base plate 1 is level. If the base plate 1 is not level, turn the crank 10 at the bottom of the base plate 1 to make the threaded rod 7 rotate in the internal thread tube 3, so that the threaded rod 7 pushes the base plate 1 back to level the base plate 1.

[0032] The device uses the ramming block 6 to strike the sliding rod 5, causing the conical head 8 and threaded rod 7 to extend into the ground, which can stably fix the device and prevent the grouting mixing equipment 2 from shifting when mixing mud and sand.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
