Description

Technical Field

[0001] This utility model relates to the field of strip-type backfilling mining and sealing devices, specifically, it relates to a strip-type backfilling mining and sealing device. Background Technology

[0002] Strip backfilling is an important technology and method for realizing underground coal mining. The equipment used in strip backfilling mainly includes surface slurry / gangue preparation stations, branch roadway mining / transportation equipment, and branch roadway sealing equipment. Among them, the surface slurry / gangue preparation station usually includes crushing, sorting, metering, mixing, and conveying systems. Compared with traditional mining, it not only requires more equipment, but also has a longer backfilling time and a longer material solidification time. Branch roadway backfilling is usually done in batches and stages, with a single roadway typically requiring 3 to 4 backfilling stages. It is estimated that filling a roadway takes 1 to 2 days, and the backfill material usually takes 5 to 7 days to solidify after backfilling.

[0003] Moreover, the strip filling mining process requires the sealing of the branch tunnel entrances: before sealing, the sealing templates and individual supports need to be transported to the entrance, and the arch is manually built or the templates are supported for sealing. The process is inefficient and costly, requiring a lot of labor and material costs.

[0004] To address the issues of investment and efficiency in sealing operations during strip backfilling mining, Chinese invention patent CN202420813019.7 discloses a tracked sealing vehicle for strip backfilling roadways in coal mines. This patent integrates the sealing template and the sealing vehicle into a single design. During the backfilling process and the solidification of the backfill material, the sealing vehicle needs to provide support and fixation and cannot move. This requires a large number of sealing vehicles, increasing the overall equipment investment cost. Moreover, the sealing vehicle occupies too much roadway passage space while it is fixed in the roadway.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

The docking mechanism is used to connect a sealing vehicle to transport and support the sealing template. The upper and lower support columns are equipped with support column hydraulic cylinders, which are hinged to the retaining wall body.

[0008] This application utilizes a retaining wall body, telescopic wall panels, telescopic hydraulic cylinders, upper and lower anti-slip columns, and a sealing template to create a retaining wall for blocking the entrance of a branch roadway.

[0014] The hook mechanism, clamping shaft, and clamping groove enable the sealing vehicle to quickly and stably transport, erect, and dismantle the sealing template.

[0015] Based on the above, the conveying head also includes a conveying telescopic arm and a snap-fit ​​telescopic arm. The conveying telescopic arm is perpendicular to the snap-fit ​​telescopic arm. The snap-fit ​​telescopic arm is located at the telescopic end of the conveying telescopic arm, and the telescopic snap-fit ​​head is located at the telescopic end of the snap-fit ​​telescopic arm.

[0016] By moving the telescopic arm, the distance between the sealing vehicle and the sealing template is extended, avoiding interference between the sealing vehicle and the upper and lower support columns of the sealing template.

[0019] Based on the above, the retaining wall bodies are hinged together and equipped with adjusting cylinders to adjust the angle between the retaining wall bodies.

Detailed Implementation

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1 like Figures 1-7 As shown, the strip filling mining sealing device of this embodiment includes a sealing template 10 and a sealing vehicle 20. The sealing template 10 can seal the entrance of the branch roadway in the strip filling mining process, which facilitates the filling operation of the branch roadway. The sealing vehicle 20 can transport and support the sealing template 10 to assist the sealing template 10 in sealing, so as to realize rapid formwork sealing, rapid formwork removal and transportation, without the need for manual formwork support and removal.

[0031] Specifically, the sealing template 10 includes a retaining wall body 11, with a telescopic wall plate 12 at the top of the retaining wall body 11. The telescopic wall plate 12 is used to provide vertical support for the retaining wall body 11. The top of the retaining wall body 11 can be configured as a box-type drawer structure, and the telescopic wall plate 12 is telescopically installed inside the top of the retaining wall body 11. A telescopic hydraulic cylinder 13 is provided between the telescopic wall plate 12 and the retaining wall body 11. The telescopic hydraulic cylinder 13 realizes the extension and retraction of the telescopic wall plate 12 and supports the telescopic wall plate 12, so that the sealing template 10 can be firmly and vertically supported as a whole at the entrance of the branch roadway, so as to effectively seal the entrance of the branch roadway.

[0032] Multiple telescopic hydraulic cylinders 13 can be installed inside the retaining wall body 11 to simultaneously apply force to the telescopic wall panels 12, such as... Figure 2 As shown, four telescopic hydraulic cylinders 13 can be installed to simultaneously apply force to the telescopic wall panel 12 so that the sealing template 10 can be firmly sealed.

[0033] The front wall of the retaining wall body 11 and the telescopic wall panel 12 can be made of corrosion-resistant polymer material. Compared with conventional materials such as wooden templates, the sealing template 10 can prevent corrosion when in long-term contact with sealing materials such as cement concrete, avoid corrosion damage, facilitate multiple cycles of use, and is lighter and stronger.

[0034] Specifically, the rear wall surface of the retaining wall body 11 is provided with an upper support column 14 and a lower support column 15. The upper support column 14 and the lower support column 15 are equipped with support column hydraulic cylinders, which are hinged to the retaining wall body 11.

[0035] The telescopic cylinder 13 and the thrust cylinder can use emulsion as power. Different sizes of ear plates can be installed at different positions on the retaining wall body 11 to hinge different types of hydraulic cylinders.

[0036] The upper support column 14 is used to provide inclined support from the rear wall of the retaining wall body 11 on the top plate of the roadway, and the lower support column 15 is used to provide inclined support from the rear wall of the retaining wall body 11 on the bottom plate of the roadway. The upper support column 14 and the lower support column 15 adopt a triangular truss support structure, which is stable when supported and enables the sealing template 10 to resist the pressure of the sealing material and effectively seal the entrance of the branch roadway.

[0037] The design of the hydraulic cylinders of the upper and lower retaining walls 14 and 15, which are hinged to the main body of the retaining wall 11, allows the angle and length of the upper and lower retaining walls to be adjusted to adapt to the roof and floor of the roadway under different working conditions, and can also be folded up during transportation.

[0038] The retaining wall body 11, telescopic wall panel 12, telescopic hydraulic cylinder 13, upper support column 14 and lower support column 15 of the sealing template 10 cooperate with each other to enable the sealing template 10 to be independently and firmly supported at the entrance of the branch roadway to complete the sealing operation. The whole can be reused. Moreover, the process of setting up and dismantling the template is simple and quick, avoiding the increase in equipment investment costs due to reliance on the sealing vehicle 20, and also avoiding the occupation of too much roadway space due to reliance on the sealing vehicle 20.

[0039] Specifically, the rear wall of the retaining wall body 11 is provided with a docking mechanism. The docking mechanism is used to connect the sealing vehicle 20, so that the sealing vehicle 20 can connect to the sealing template 10 through the docking mechanism to transport the sealing template 10 and provide support for the sealing template 10 when it is erected and dismantled.

[0040] The blocking template 10 and the blocking vehicle 20 are designed as separate units. One blocking vehicle 20 can transport, support and dismantle multiple different blocking templates 10 at different times, avoiding excessive capital investment due to the use of too many blocking vehicles 20.

[0041] In this application, the retaining wall body 11, telescopic wall panel 12, telescopic hydraulic cylinder 13, upper support column 14, and lower support column 15 of the sealing template 10 make the sealing template 10 a retaining wall for sealing the entrance of the branch roadway. The process of setting up and dismantling the template is simple and quick. It can independently seal the entrance of the branch roadway without relying on the sealing vehicle 20, thus avoiding occupying too much roadway space. The sealing vehicle 20 is connected to the sealing template 10 through the docking mechanism, which can mechanize the transportation and support of the sealing template 10, saving labor costs. Moreover, one sealing vehicle 20 can correspond to multiple sets of sealing templates 10, and the sealing template 10 can be recycled and reused, saving equipment costs.

[0042] Example 2 Based on Embodiment 1, in this embodiment, the sealing template 10 is composed of at least two retaining wall bodies 11 spliced ​​together from left to right, and is used to set the overall width in a modular splicing manner.

[0043] For example Figure 2 , Figure 3 , Figure 5 As shown, by splicing and combining the three sealing templates 10 to adapt to the width of the branch tunnel entrance, all three sealing templates 10 can be firmly supported at the branch tunnel entrance, which helps to improve the applicability and strength of the sealing templates 10.

[0044] Example 3 Based on Embodiment 1 or Embodiment 2, the docking mechanism includes two horizontally arranged card seats 16, and the sealing vehicle 20 includes a transport head, which includes two telescopic card heads 21. When the two telescopic card heads 21 extend between the two card seats 16, they can be engaged with the two card seats 16 respectively, so that the sealing vehicle 20 can connect to the sealing template 10.

[0045] The telescopic clamp 21 of the conveyor head of the blocking vehicle 20 is horizontally inserted into the two clamp seats 16 from the middle to both sides, which can realize the quick connection between the blocking vehicle 20 and the blocking template. Moreover, when inserted, the blocking vehicle 20 can lift the blocking template 10 upward and support it forward, so that the blocking vehicle 20 can carry and support the blocking template 10.

[0046] When the telescopic clamp head 21 does not need to be connected to the sealing template 10, it can be retracted inward to reduce the volume of the conveying head of the sealing vehicle 20.

[0047] In this embodiment, the sealing vehicle 20 and the sealing template 10 can be quickly connected through the card holder 16 and the telescopic card head 21, and the retraction of the telescopic card head 21 can reduce the volume of the conveying head of the sealing vehicle 20.

[0048] Example 4 Based on embodiment 3, in this embodiment, as Figure 1 , Figure 2 As shown, the card holder 16 adopts a shaft seat, which includes a vertical card shaft. The telescopic card head 21 is provided with a card slot that can be embedded in the card shaft. The card shaft can be embedded into the card slot of the telescopic card head 21 to realize the quick connection between the sealing vehicle 20 and the sealing template 10.

[0049] Due to the cooperation between the clip shaft and the clip slot, when the telescopic clip head 21 is engaged with the clip seat 16, the telescopic clip head 21 can move up and down within the clip seat 16, that is, move along the axial direction of the clip shaft until it contacts the ear plate of the shaft seat.

[0050] Furthermore, the conveying head also includes a hook mechanism 22, which is used to lift the sealing template 10 upward. When the hook mechanism 22 lifts the sealing template 10 upward, the telescopic clamp 21 and the clamp seat 16 move relative to each other. The hook of the hook mechanism 22 is located in front of the telescopic clamp 21 and is used to connect the sealing template to hook and lift the sealing template 10.

[0051] Thus, when the sealing vehicle 20 needs to transport the sealing template 10, the sealing template 10 can be lifted by the cooperation of the hook mechanism 22 and the telescopic clamp 21; when the sealing template 10 needs to be supported, the hook mechanism 22 can be lowered and separated from the sealing template 10 first, so that the bottom of the sealing template 10 is grounded, and then the transport head of the sealing vehicle 20 is used to support the sealing template 10. After the support is completed, the telescopic clamp 21 is retracted and separated from the sealing template 10; when the sealing template 10 needs to be disassembled, the telescopic clamp 21 is first connected to the clamp seat 16, then the telescopic wall panel 12 of the sealing template 10 is lowered, and the upper and lower support columns 14 and 15 are retracted. Finally, the hook mechanism 22 is used to lift the sealing template 10, which facilitates the transport of the sealing template 10.

[0052] In other embodiments, a slot adapted to the shape of the telescopic card head 21 can be provided in the card holder 16 so that the telescopic card head 21 can be embedded in the slot of the card holder 16.

[0053] The hook mechanism 22, the clamping shaft and the clamping groove enable the sealing vehicle 20 to quickly and stably transport, support and dismantle the sealing template 10.

[0054] Example 5 Based on Embodiment 2, Embodiment 3, or Embodiment 4, the retaining wall bodies 11 are further hinged together and equipped with an adjusting cylinder 17 for adjusting the angle between the retaining wall bodies 11.

[0055] The two ends of the adjusting cylinder 17 are respectively hinged to the first adjusting ear and the second adjusting ear. The first adjusting ear and the second adjusting ear are respectively set on the two retaining wall bodies 11. There is a front-to-back gap between the first adjusting ear and the second adjusting ear so that the angle between the two sealing templates 10 can be adjusted when the adjusting cylinder 17 extends and retracts. For example, the first adjusting ear can be set on the card seat 16 and the second adjusting ear can be set on the rear wall surface of the retaining wall body 11.

[0056] The angle between the retaining wall bodies 11 can be adjusted by the adjusting cylinder 17 between the retaining wall bodies 11, and by adjusting the angle between the retaining wall bodies 11, the multiple sealing templates 10 can be formed to adapt to the shape of the branch roadway entrance, which is beneficial to improving the applicability of the sealing templates 10.

[0057] Example 6 Based on embodiment 3, the conveying head also includes a conveying telescopic arm 23 and a snap-fit ​​telescopic arm 24. The conveying telescopic arm 23 is perpendicular to the snap-fit ​​telescopic arm 24. The snap-fit ​​telescopic arm 24 is located at the telescopic end of the conveying telescopic arm 23, and the telescopic snap-fit ​​head 21 is located at the telescopic end of the snap-fit ​​telescopic arm 24.

[0058] By extending and retracting the telescopic arm 23, the distance between the blocking vehicle 20 and the blocking template 10 can be increased or decreased, preventing the blocking vehicle 20 from interfering with the upper and lower support columns 14 and 15 of the blocking template 10. The telescopic clamp head 21 can be extended and retracted by snapping the telescopic arm 24.

[0059] Example 7 Based on embodiment 6, the conveying head also includes a rotating base 25, with a rotating shaft seat at the bottom of the rotating base 25. The rotating shaft seat can be powered by a hydraulic motor. The conveying telescopic arm 23 is hinged to the top of the rotating base 25, and a swing jack 26 is provided between the rotating base 25 and the conveying telescopic arm 23 to make the conveying telescopic arm 23 swing up and down.

[0060] The sealing template 10 is lifted by swinging the telescopic boom 23 up and down using the swing jack 26. This method can replace the method of lifting the sealing template 10 using the hook mechanism 22, or both methods can be implemented at the same time.

[0061] By swinging the jack 26, the telescopic arm 23 can be moved up and down, allowing the blocking vehicle 20 to lift the blocking template 10 further upward by swinging up and down, thus enhancing the passability of the blocking vehicle 20 when moving the blocking template 10; by rotating the base 25, the telescopic arm 23 can be rotated, allowing the blocking vehicle 20 to adjust the position of the blocking template 10 on the blocking vehicle 20 by rotating, thus enhancing the passability of the blocking vehicle 20 when moving the blocking template 10.

[0062] Example 8 Based on Embodiment 1 or Embodiment 2, the thrust cylinder is connected to a retraction mechanism 18, which is used to adjust the angle between the thrust cylinder and the retaining wall body 11.

[0063] The angle of the thrust cylinder can be adjusted mechanically by the retraction mechanism 18, avoiding manual intervention.

[0064] Example 9 Based on embodiment 8, the retracting mechanism 18 adopts a retracting hydraulic cylinder, and a retracting connecting plate 19 is provided between the hydraulic cylinders of the mast column. The two ends of the retracting hydraulic cylinder are respectively hinged to the retracting connecting plate 19 and the rear wall.

[0065] The retraction and extension cylinder can be connected to the downhole hydraulic system to quickly adjust the angle of the thrust cylinder. The retraction and extension cylinder and the thrust cylinder are connected through the retraction and extension connecting plate 19, and the retraction and extension cylinder can control the adjustment angle of multiple thrust cylinders at the same time.

[0066] Example 10 Based on Embodiment 1, the blocking vehicle 20 adopts a tracked chassis, the tracked walking mechanism is the walking execution mechanism of the blocking vehicle 20, and the rotating base 25 is installed on the tracked chassis.

[0067] The tracked chassis is equipped with a pusher at the front, which can be raised, lowered, and pushed to clear obstacles and debris from the road, ensuring smooth and flat road surfaces.

[0068] The tracked chassis is equipped with retractable support legs at the bottom to ensure the stability and reliability of the sealing vehicle 20 when the transport head lifts the sealing template 10.

[0069] The blocking vehicle 20 can be equipped with a dual fluid supply system of emulsion / hydraulic oil, and has an emulsion pump and a hydraulic oil pump. The emulsion fluid supply system provides power to the telescopic cylinder 13, the thrust cylinder, the adjustment cylinder 17 and the retraction cylinder of the blocking template 10; the hydraulic oil supply system provides power to the hook mechanism 22, the transport telescopic arm 23, the snap-fit ​​telescopic arm 24, the rotating base 25, the swing jack 26, the tracked chassis, the pusher and the support legs.

[0071] By setting up a tracked chassis, pusher, and support legs, the sealing vehicle 20 is better adapted to the underground environment, which is beneficial for the sealing vehicle 20 to transport and support the sealing template 10.
