Description

Technical Field

[0001] This utility model belongs to the field of coal mine collapse rescue technology, and in particular relates to a coal mine collapse area clearing and support device. Background Technology

[0002] Because coal mining operations are conducted underground, in order to ensure the safety of mining personnel and equipment, support structures, mostly hydraulic support structures, are often installed on the top and sides of the working roadways.

[0003] However, in actual operations, tunnel collapses are common. Once a tunnel collapses, the accumulated soil and rocks must be cleared immediately to clear the obstacles and facilitate rescue personnel's access to the burial site.

[0004] However, during the process of clearing obstacles created by the landslide, the tunnels in the landslide area are prone to further landslides, which pose a serious threat to the lives of the clearing workers.

[0005] Therefore, in actual construction, operators support the collapsed area with support structures, such as support plates and support rods, on the top surface of the tunnel. However, the stability of this support method is not high. This is because, firstly, the area of ​​accumulated gravel and soil in the collapsed area is not convenient for installing support devices, and secondly, the support surface is small, while tunnel collapses often involve a large area of ​​collapse at the top of the tunnel. Therefore, the stability of the support is not high due to the small support surface.

[0006] The drawback of the above method is that it cannot simultaneously support the tunnel wall. Once a large amount of soil collapses from the tunnel wall, it not only reforms the landslide obstacle, but also poses a serious threat to the life safety of the clearing personnel.

[0007] Therefore, by using a method that can support the collapsed area (collapsed obstacle), not only can the safety of the clearing work be ensured, but secondary collapses and the creation of secondary obstacles can also be effectively avoided. This is of great significance for improving the clearing of obstacles in the roadway during the rescue process, and at the same time, it provides a foundation for more efficient rescue of trapped personnel. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a device for clearing obstacles and providing support in coal mine rescue collapse areas.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A coal mine rescue landslide area clearing and support device includes a cover support mechanism that covers the construction area.

[0011] The cover support mechanism includes a lane support structure supported on the lane wall, and the lane support structure includes a pair of lane support plates spaced apart; the lane support plates are supported by a first hydraulic cylinder structure.

[0012] It also includes a road top support structure installed on the top of the road top support plate, the road top support structure including the road top support plate, and a second hydraulic cylinder structure for pushing the road top support plate up and down and for flipping support.

[0013] Preferably, the first hydraulic cylinder structure includes a first hydraulic cylinder, and top rods for assembling and connecting the first hydraulic cylinder are detachably installed on the side walls of the two side alley support plates facing each other.

[0014] The push rod is connected to the piston rod and cylinder of the first hydraulic cylinder via flanges.

[0015] Preferably, the first hydraulic cylinder structure further includes a plurality of guide rail structures that cooperate with the first hydraulic cylinder;

[0016] The guide rail structure includes telescopic guide rails that can be detachably installed on the side alley support plates.

[0017] The telescopic guide rails are connected by mounting rods via flanges.

[0018] Preferably, end protection brackets are detachably installed on the side walls on both sides of the alley support plate;

[0019] A channel is formed between the end protective brackets.

[0020] Preferably, a number of rollers are installed at the bottom of the alleyway support plate and the bottom of the end protection bracket.

[0021] Preferably, the transverse cross-sectional shape of the end protection bracket is L-shaped;

[0022] Mounting bosses are welded to the upper and lower ends of the end protection bracket, and mounting seats that mate with the mounting bosses are welded to the side wall of the alley support plate. The mounting bosses and mounting seats are fastened together with bolts.

[0023] Preferably, the roof guard plate is hingedly mounted with a support plate;

[0024] A lifting bracket is fixedly connected to the bottom of the bracket plate;

[0025] A connecting beam is fixedly connected between the support plate and the lifting support.

[0026] Preferably, the second hydraulic cylinder structure includes a second hydraulic cylinder hinged to the connecting beam;

[0028] Preferably, the second hydraulic cylinder structure further includes a lifting hydraulic cylinder for lifting the connecting beam;

[0029] The top of the alley support plate is fixedly connected to a cylinder base for fixing and installing a lifting hydraulic cylinder.

[0030] The piston rod of the lifting hydraulic cylinder is fixedly installed at the bottom of the connecting beam.

[0031] This utility model has the following beneficial effects:

[0032] 1. The obstacle clearing and support device disclosed in this utility model provides support for the top of the roadway in the work area. Therefore, with the cooperation of a pair of roadway top protection plates and a pair of roadway side support plates, the roadway top and side, which are prone to secondary collapse, are supported.

[0046] Example 1

[0047] like Figure 1-6 As shown, a coal mine rescue landslide area clearing and support device includes a cover support mechanism that covers the construction area. The cover method creates a safe working environment for localized operations in the landslide debris (rubble and soil) accumulation area.

[0048] Specifically, the cover support mechanism includes a lane support structure supported on the lane wall, and the lane support structure includes a pair of lane support plates 1 (symmetrically arranged on the left and right sides) spaced apart; the lane support plates 1 are supported by a first hydraulic cylinder structure.

[0049] Specifically, the first hydraulic cylinder structure includes a first hydraulic cylinder 32, and push rods 31 that are detachably installed on the side walls of the left and right sidewall support plates 1 facing each other (specifically, a mounting connection seat is welded and fixed on the push rod 31, and the mounting connection seat is fastened to the sidewall support plate 1 by bolts).

[0050] Meanwhile, the push rod 31 is connected to the plunger rod and cylinder of the first hydraulic cylinder 32 via flanges (the plunger rod and cylinder are respectively fixedly connected to mating flanges, which are fastened to the flanges on the push rod 31 by bolts).

[0051] During the work, the clearing personnel first carried out preliminary clearing around the collapsed area, and then pushed the side support plates 1 along the sides of the collapsed material accumulation area to isolate the collapsed material from the side support. Then, the first hydraulic cylinder 32 was installed in the above manner.

[0052] In actual operation, according to the actual spacing of the side roadway support plates 1, the top rods 31 of the corresponding length are installed on the side roadway support plates 1.

[0053] Subsequently, the first hydraulic cylinder 32 is installed and opened. Under the push of the first hydraulic cylinder 32, the two side roadway support plates 1 are pushed toward the roadway until they completely contact the roadway. In this way, the roadway on both sides of the clearing area is in a supported state, ensuring the safety of the workers and preventing the roadway from collapsing and causing further rockfall obstacles.

[0054] During the pushing process, in order to reduce pushing resistance, several rollers 11 (preferably casters) are installed at the bottom of the aforementioned alleyway support plate 1 and the bottom of the following end protection bracket 2. The advantages of using casters are:

[0055] Once the obstacles have been cleared, the operator can easily push the entire device to the next location that needs clearing (i.e., push it in a non-disassembled state to avoid secondary assembly, thereby increasing the efficiency of clearing roadway collapse obstacles, because it is necessary to deal with collapses in multiple locations within the roadway).

[0056] During the hydraulic structure propulsion process, the two side lane support plates 1 are pushed and supported on the lane in a rolling manner. During this process, the piston rod and cylinder of the first hydraulic cylinder 32 push the two side lane support plates 1 to move away from each other.

[0057] In order to further increase the movement stability of the lane support plate 1 during the pushing process, the above-mentioned first hydraulic cylinder 32 structure also includes a pair of guide rail structures that are symmetrically arranged front and rear and cooperate with the first hydraulic cylinder 32.

[0058] Specifically, the guide rail structure includes telescopic guide rails 52 that are detachably mounted on the two side support plates 1. (The telescopic guide rails 52 are conventional telescopic sliding guide rail sleeve structures disclosed in the prior art, specifically including a guide rail sleeve and a slide rail rod slidably connected inside the guide rail sleeve.) Mounting seats are fixedly connected to the guide rail sleeves, and the mounting seats are fastened to the support plates 1 by bolts.

[0059] Meanwhile, the telescopic guide rails 52 are connected by flanges with mounting rods 51. That is, during the assembly of the alley support plate 1, the telescopic guide rails 52 are pre-installed on the corresponding alley support plate 1, and then the mounting rods 51 are connected to form an integrated structure of the alley support plates 1 on both sides. During the pushing process of the alley support plate 1, it is pushed by the telescopic movement of the telescopic guide rails 52 installed on each side.

[0060] Example 2

[0061] like Figure 1-6 As shown, this embodiment is based on the structure of embodiment 1. The working area is supported by the above method. In order to avoid the collapse of the non-supported area of ​​the lane and the large amount of collapsed obstacles from the front and rear ends of the lane support plate 1 during the actual work process, so as to increase the amount of obstacle removal, end protection brackets 2 are detachably installed on the side walls of the front and rear sides of the lane support plate 1 respectively (the detachable method is: the upper and lower ends of the end protection bracket 2 are respectively welded with mounting protrusions, and the side walls of the lane support plate 1 are welded with assembly seats that cooperate with the mounting protrusions. The mounting protrusions and the assembly seats are fastened together by bolts).

[0062] A passage is formed between the end-end protective supports 2 (the transverse cross-sectional shape of the end-end protective supports 2 is provided for easy access by operators). Under the protection of the end-end protective supports 2, the entry of large amounts of collapsed debris from non-supported roadways is prevented. Furthermore, the passage is designed as a clearance route for removing obstacles.

[0063] Example 3

[0064] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 2, includes a road top support structure installed at the top of the roadway support plate 1 to prevent secondary collapse of the roadway top during the obstacle clearing process. The road top support structure includes a road top protection plate 45 and a second hydraulic cylinder structure for pushing the road top protection plate 45 up and down and flipping for support.

[0065] Specifically, the roof guard plate 45 is hinged to a support plate 43 (a pair of hinge slots are opened on the support plate 43, and a pair of hinge tongues are welded to the roof guard plate 45 and respectively hinged to the hinge slots).

[0066] Meanwhile, a lifting bracket 41 is fixedly connected to the bottom of the support plate 43; a connecting beam 47 is fixedly connected between the center of the support plate 43 and the lifting bracket 41. Additionally, support rods 42 are fixedly installed between the ends of the support plate 43 and the lifting bracket 41.

[0067] The second hydraulic cylinder structure includes a second hydraulic cylinder 46 hingedly mounted on the connecting beam 47. Specifically, a hinge groove is provided at the lower end of the connecting beam 47, and a hinge tongue is fixedly welded to the cylinder barrel of the second hydraulic cylinder 46. The hinge tongue is hinged in the hinge groove by a pin. At the same time, the plunger rod of the second hydraulic cylinder 46 is hinged to the bottom outer side of the tunnel roof guard plate 45 (the method is as follows: a hinge seat is welded to the bottom outer side of the tunnel roof guard plate 45, a hinge collar is welded to the plunger rod, a hinge shaft is fixedly connected to the hinge seat, and the hinge collar is hinged to the hinge shaft).

[0068] Meanwhile, the second hydraulic cylinder 46 structure also includes a lifting hydraulic cylinder 44 for lifting the connecting beam 47; specifically, the cylinder base of the lifting hydraulic cylinder 44 is fixedly installed on the front and rear sides of the top of the alley support plate 1; the lifting hydraulic cylinder 44 is installed on the top of the cylinder base, and the plunger rod of the lifting hydraulic cylinder 44 is fixedly installed on the bottom of the connecting beam 47.

[0069] During the support process, the operator uses the lifting hydraulic cylinder 44 to raise the support plate 43 and the roadway roof guard plate 45 to a position close to the roadway roof. Then, the second hydraulic cylinder 46 pushes to open the roadway roof guard plate 45. Under the push of the hinged second hydraulic cylinder 46, the roadway roof guard plate 45 gradually flips to a horizontal position and supports the top of the roadway. Then, the lifting hydraulic cylinder 44 is used again to lift it up to increase the support force.

[0070] This method achieves roof support for the work area roadway. Therefore, with the cooperation of a pair of roof support plates 45 and a pair of side support plates 1, the roof and side of the roadway, which are prone to secondary collapse, are supported. Furthermore, the cooperation of the roof support plates 45 and the side support plates 1 forms a U-shaped support cover, thereby ensuring the safety of operators during the clearing and rescue process.

[0071] Example 4

[0072] like Figure 1-6As shown, this embodiment, based on the structure of embodiment 3, is identical to the existing hydraulic circuit system for controlling hydraulic cylinders. The lifting hydraulic cylinder 44, the second hydraulic cylinder 46, and the first hydraulic cylinder 32 all operate using a hydraulic circuit system disclosed in the prior art. Specifically, the hydraulic circuit system includes a hydraulic oil tank, an oil pump for pumping hydraulic oil, a hydraulic oil pipeline system for conveying hydraulic oil, and a control valve structure for controlling the pumping of hydraulic oil into the lifting hydraulic cylinder 44, the second hydraulic cylinder 46, and the first hydraulic cylinder 32. During operation, as in the existing method, the lifting hydraulic cylinder 44 operates synchronously up and down, while the lifting hydraulic cylinder 44, the second hydraulic cylinder 46, and the first hydraulic cylinder 32 operate independently. The second hydraulic cylinder 46 and the first hydraulic cylinder 32 also operate independently.

[0073] Specifically, the hydraulic cylinder works by pumping hydraulic oil into and out of the cylinder (oil-push plunger rod). Therefore, the synchronous or independent operation of the lifting hydraulic cylinder 44, the second hydraulic cylinder 46, and the first hydraulic cylinder 32 is achieved using valve control techniques disclosed in the prior art. For example, the inlet and outlet pipes of the four lifting hydraulic cylinders 44 can be connected in series to a single oil pipeline. The valves on this oil pipeline can then control the inlet and outlet of the four lifting hydraulic cylinders 44 synchronously, achieving synchronized operation. Similarly, the independently operating second hydraulic cylinder 46 and first hydraulic cylinder 32 are controlled by valves on their independent inlet and outlet oil pipelines.

[0074] Those skilled in the art can easily understand, by consulting technical manuals and dictionaries, how the aforementioned hydraulic cylinder is controlled by the hydraulic circuit system disclosed in the prior art.

[0075] The driving force (model) of the aforementioned lifting hydraulic cylinder 44, the second hydraulic cylinder 46, and the first hydraulic cylinder 32 is selected according to the specific dimensions of the roadway roof support plate 45 and the roadway side support. For example, in order to increase the support surface (to cope with severe collapse), a larger size roadway roof support plate 45 and roadway side support are used, so a hydraulic cylinder with a larger driving force is selected.

[0076] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
