Description

Technical Field

[0001] The present invention relates to the field of mining equipment, and in particular to a mining grouting filling dehydration device and method. Background Art

[0002] In the construction of mining construction projects, grouting to fill cracks in geotechnical foundations is one of the important construction processes. It uses appropriate methods to inject certain solidifying slurries into the cracks or gaps in the geotechnical foundation, and improves the physical and mechanical properties of the geotechnical foundation cracks through replacement, filling and extrusion.

[0003] Since the upper layer of the slurry after filling is a water layer, a phenomenon of loose connection will occur, so the accumulated water in the water layer needs to be discharged outward. In order to speed up the drainage efficiency and improve the filling effect, the existing invention patent application with application number 201810081595.6 discloses a mining grouting filling dehydration device and method, which uses a grouting pressing plate to press the filling slurry to accelerate the separation of water and material and improve the filling effect. However, it is inevitable that the bottom of the pressing plate will also adhere to the upper part of the filling material, and as the filling compaction continues to increase, the amount of material adhered to the bottom of the pressing plate will increase. Therefore, it is necessary to clean the bottom of the pressing plate after use in time. The existing technology is manual cleaning, and the degree of automation is low. Therefore, a mining grouting filling dehydration device and method are proposed to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a mining grouting filling dehydration device and method in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A mining grouting filling and dewatering device includes a shell, a partition is provided in the middle of the shell, hydraulic rods are symmetrically provided at the four corners of the lower end of the partition, the end of the hydraulic rod away from the partition is fixedly connected to a sliding assembly, the sliding assembly and the guide assembly are slidably matched, the guide assembly is fixedly arranged at the end of the dewatering assembly, the dewatering assembly includes a first splicing plate and a second splicing plate, the first splicing plate and the second splicing plate are both composed of a vertical plate and a plurality of horizontal plates, the gap distance between two adjacent horizontal plates is the same as the width of a horizontal plate, the first splicing plate and the second splicing plate are spliced ​​together, and the middle ends of the first splicing plate and the second splicing plate are both provided with a waist-shaped slide groove, the waist-shaped slide groove is slidably connected with a support assembly, and the end of the support assembly away from the dewatering assembly is fixedly arranged at the lower end of the partition.

[0007] Preferably, the sliding assembly includes a sleeve, a connecting rod and a rolling column. The connecting rod is rotatably connected in the rotating hole of the sleeve, and rolling columns are rotatably provided at both ends of the connecting rod.

[0008] The rotation arrangement between the rolling column and the connecting rod can prevent the rolling column from being locally subjected to stress and wear, thereby extending the service life of the rolling column.

[0009] Preferably, at least two protrusions are arranged on the outer peripheral surface of each rolling cylinder at unequal intervals.

[0010] Such an arrangement can cause the rolling column to vibrate during the rolling process along the guide groove, thereby further promoting the separation of the adhesion blocks attached to the surfaces of the first splicing plate and the second splicing plate.

[0011] Preferably, the guide assembly includes a guide block and a guide slot, and the guide slot is provided through the side surface of the guide block.

[0012] With such an arrangement, the first splicing plate and the second splicing plate can be caused to rotate relative to each other through the guiding effect of the guide slot.

[0013] Preferably, the guide groove is an cambered groove, and the width of the guide groove is slightly larger than the diameter of the rolling column.

[0014] Such an arrangement can ensure that there is sufficient movable clearance when the rolling column rolls in the guide slot, so that under the action of the protrusion, vibration is generated between the protrusion and the guide slot.

[0015] Preferably, the support assembly includes two end seats, two telescopic rods and a pull rod, both ends of the pull rod are provided with end seats, and the upper end of each end seat is fixedly provided with a telescopic rod.

[0016] Such a configuration is used to support the middle portions of the first and second splicing plates, so that when the telescopic rod is retracted to the minimum length, the first and second splicing plates can rotate relative to each other around the pull rod under the action of the lever fulcrum of the pull rod.

[0017] Preferably, the lower portion of the shell has a lower port, and the outer dimensions of the lower port are adapted to the outer dimensions of the dehydration assembly.

[0018] Preferably, a water pump is provided at the upper end of the partition, the water inlet pipe of the water pump is fixedly connected to a water suction component, and the water suction port of the water suction component is located above the dehydration component.

[0019] Such an arrangement is used to timely discharge the squeezed upper layer water during the dehydration and compaction process of the material at the crack by the dehydration component.

[0020] Preferably, a top cover is fixedly provided above the shell, and a hook ring is provided at the center of the upper end of the top cover.

[0021] With such arrangement, the device can be freely hung to any desired filling position by means of the hook, making it easy to move the device.

[0022] A method for using a mining grouting filling and dehydration device comprises the following steps:

[0023] a. When using the mining grouting and dehydration device, the user first lifts the device to the location of the crack to be dehydrated using a hook ring, and places the shell flat on the ground. In the initial state, the four hydraulic rods are in a retracted state. At this time, the first splicing plate and the second splicing plate are arranged in a cross-shaped and inclined manner;

[0024] b. When in use, the four hydraulic rods move downward simultaneously, thereby driving the sliding assembly downward, and the rolling column moves downward along the guide chute. Under the guiding drive of the guide chute, the first splicing plate and the second splicing plate gradually approach each other while rotating around the waist-shaped chute, and finally move until the upper end surfaces of the first splicing plate and the second splicing plate are on the same horizontal plane;

[0025] c. At this time, the first splicing plate and the second splicing plate are spliced ​​together to form a whole without a gap. At this time, as the hydraulic rod continues to move downward, the first splicing plate and the second splicing plate cannot move further due to mutual limitation, and the rolling column moves to the lowest position of the guide chute and abuts against the bottom of the guide chute, so that the dehydration assembly formed by the first splicing plate and the second splicing plate moves horizontally downward to dehydrate the material filled in the crack;

[0026] d. After dehydration is completed, the hydraulic rod drives the dehydration assembly to move upward. When the first splicing plate and the second splicing plate move upward to the maximum contraction distance position of the telescopic rod, the first splicing plate and the second splicing plate rotate with the pull rod as the lever fulcrum, so that the first splicing plate and the second splicing plate rotate from the whole to the cross state. At this time, due to the cross rotation of the first splicing plate and the second splicing plate, the adhesion blocks attached to the lower surfaces of the first splicing plate and the second splicing plate are forced to break away. In addition, the cross rotation of the first splicing plate and the second splicing plate can also avoid the formation of large adhesion blocks under the first splicing plate and the second splicing plate.

[0027] e. Even if there are still small pieces of adhesion at the horizontal plate position of the first splicing plate and the second splicing plate, it is only necessary to use an iron rod or other instrument to simply knock the first splicing plate and the second splicing plate to cause the adhesion blocks underneath to separate. Compared with the existing technology, less manual operation is required, and it has an appropriate degree of automation, which can automatically clean the adhesion blocks under the dehydration component, saving time and effort.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] After dehydration is completed, when the first splicing plate and the second splicing plate move upward to the maximum contraction distance position of the telescopic rod, the first splicing plate and the second splicing plate rotate with the pull rod as the lever fulcrum, so that the first splicing plate and the second splicing plate rotate from a whole to a cross state. At this time, due to the cross rotation of the first splicing plate and the second splicing plate, the adhesion blocks attached to the lower surfaces of the first splicing plate and the second splicing plate are forced to separate. In addition, the cross rotation of the first splicing plate and the second splicing plate can also avoid the formation of large adhesion blocks under the first splicing plate and the second splicing plate. Compared with the existing technology, less manual operation is required, it has an appropriate degree of automation, and can automatically clean the adhesion blocks under the dehydration component, saving time and effort.

[0052] A method for using a mining grouting filling and dehydration device comprises the following steps:

[0053] a. When using the mining grouting and dehydration device, the user first lifts the device to the location of the crack to be dehydrated using the hook ring 21, and places the shell 1 flat on the ground. In the initial state, the four hydraulic rods 3 are in a retracted state. At this time, the first splicing plate 61 and the second splicing plate 62 are arranged in a cross shape and tilted;

[0054] b. When in use, the four hydraulic rods 3 move downward simultaneously, thereby driving the sliding assembly 4 downward, and the rolling column 43 moves downward along the guide slot 52. Under the guiding drive of the guide slot 52, the first splicing plate 61 and the second splicing plate 62 gradually approach each other while rotating around the waist-shaped slot 63, and finally move until the upper end surfaces of the first splicing plate 61 and the second splicing plate 62 are in the same horizontal plane;

[0055] c. At this time, the first splicing plate 61 and the second splicing plate 62 are spliced ​​together to form a whole without a gap. At this time, as the hydraulic rod 3 continues to move downward, the first splicing plate 61 and the second splicing plate 62 cannot move further due to mutual limitation, and the rolling column 43 moves to the lowest position of the guide chute 52 and abuts against the bottom of the guide chute 52.

[0056] d. After the dehydration is completed, the hydraulic rod 3 drives the dehydration assembly 6 to move upward. When the first splicing plate 61 and the second splicing plate 62 move upward to the maximum contraction distance position of the telescopic rod 72, the first splicing plate 61 and the second splicing plate 62 rotate with the pull rod 73 as the lever fulcrum, so that the first splicing plate 61 and the second splicing plate 62 rotate from the whole to the cross state. At this time, due to the cross rotation of the first splicing plate 61 and the second splicing plate 62, the adhesion blocks attached to the lower surfaces of the first splicing plate 61 and the second splicing plate 62 are forced to separate. In addition, the cross rotation of the first splicing plate 61 and the second splicing plate 62 can also avoid the formation of a large adhesion block under the first splicing plate 61 and the second splicing plate 62;

[0057] e. Even if there are still small pieces of adhesion at the horizontal plate position of the first splicing plate 61 and the second splicing plate 62, it is only necessary to use an iron rod or other instrument to simply knock the first splicing plate 61 and the second splicing plate 62 to cause the adhesion blocks thereunder to separate.
