Description

Technical Field

[0001] This application relates to the technical field of construction machinery, and particularly to a pedestrian passage module. This application also relates to an extra-high mining height hydraulic support having the pedestrian passage module. Background Art

[0002] Currently, in some domestic mining areas, the general coal seam thickness is about 10 meters. The caving mining technology and the slicing mining production method are mainly used for mining, with a long mining cycle, serious coal retention and waste. In order to meet the requirements of energy conservation, green, high-efficiency, high-yield and sustainable mining, more and more domestic mining areas have begun to adopt the extra-high mining height fully-mechanized mining of thick coal seams.

[0003] In the prior art, extra-high mining height hydraulic supports have been widely used, and the support height is generally between 7 meters and 10 meters. Currently, a pedestrian passage is provided in the extra-high mining height hydraulic support. The height of the pedestrian passage is 1.3 meters. Coupled with the height of the operator of 1.75 meters, the effective height space that can be observed by people is 3.05 meters. However, when the mining height of the working face reaches more than 6 meters, the staff cannot effectively observe and operate the situation of the working face, so that the normal operation and high-efficiency production of the extra-high mining height working face cannot be guaranteed. At the same time, in the large mining height working state, the upper part of the support cannot be effectively overhauled. Therefore, it is necessary for those skilled in the art to timely provide an extra-high mining height hydraulic support and its pedestrian passage module that are beneficial to observing the working face and overhauling the shearer on the upper part of the support.

[0015] In some embodiments, a rotary drive assembly is further included. One end of the rotary drive assembly is hinged to the fixed connection beam, and the other end is hinged to the second pedestrian passage layer.

[0016] In some embodiments, the second pedestrian passage layer is provided with a first hinge seat and a group of second hinge seats, the fixed connection beam is provided with a third hinge seat and a group of fourth hinge seats. The first hinge seat is used for connecting the movable end of the rotary drive assembly, the third hinge seat is connected to the fixed end of the rotary drive assembly, and a group of second hinge seats are respectively connected to a group of fourth hinge seats.

[0017] In some embodiments, a group of fixed connecting rods are further included. The group of fixed connecting rods are detachably connected between the second pedestrian passage layer and a group of columns, and the group of fixed connecting rods are used to support the second pedestrian passage layer.

[0018] In some embodiments, the second pedestrian passage layer includes a flip guard plate. The flip guard plate is provided with a group of first supports, and a group of columns are provided with a group of second supports. The group of fixed connecting rods are connected to the group of first supports and the group of second supports.

[0019] In some embodiments, the second pedestrian passage layer further includes:

[0020] A liftable pedal, which is arranged on the flip guard plate;

[0021] A lift drive assembly, which is arranged between the flip guard plate and the liftable pedal, and is used to drive the liftable pedal to lift.

[0022] In some embodiments, a guardrail is provided on the liftable pedal.

[0023] This application also provides an extra-high mining height hydraulic support, which includes the pedestrian passage module according to any one of the above.

[0024] Compared with the above background art, the pedestrian passage module provided by the embodiments of the present application includes a base, a group of columns, a first pedestrian passage layer, a second pedestrian passage layer, and a walking and climbing assembly. Among them, the group of columns is arranged on the base, the first pedestrian passage layer is arranged on the base, and the first pedestrian passage layer is used for staff to stand and walk. The second pedestrian passage layer is rotatably connected to the group of columns, the second pedestrian passage layer is arranged above the first pedestrian passage layer, and the second pedestrian passage layer is used to rotate relative to the group of columns to form a platform for staff to stand and walk. The walking and climbing assembly is arranged between the group of columns and is used for the staff on the first pedestrian passage layer to transfer to the second pedestrian passage layer. The above pedestrian passage module is mainly applied to ultra-high mining height hydraulic supports to solve the problem that due to the large mining height of the supports (the mining height of ultra-high mining height supports is generally 8 meters to 10 meters), workers cannot see the working states of the front coal shearer and scraper conveyor at the first pedestrian passage layer, so they cannot effectively control the equipment.

[0025] Setting a double pedestrian passage layer in the ultra-high mining height support can view the equipment status and coal cutting situation during the coal mining process. The beneficial effects of the pedestrian passage module set in this way mainly include:

[0026] First, due to the large mining height of the ultra-high mining height hydraulic support, rock burst is likely to occur. By setting a double pedestrian passage layer, workers can work on the second pedestrian passage layer, which can avoid the harm caused by rock burst to the staff, thereby improving the safety of the operation environment and ensuring the normal and efficient production of the high mining height working face.

[0027] Second, it can solve the problem that due to the large mining height of the support (the mining height of ultra-high mining height supports is generally 8 meters to 10 meters), workers cannot see the working states of the front coal shearer and scraper conveyor at the first pedestrian passage layer, so they cannot effectively control the equipment. By setting a double pedestrian passage layer, the equipment status and coal cutting situation can be viewed during the coal mining process, so as to facilitate controlling the equipment according to the actual situation, which is beneficial to ensuring the normal and efficient production of the high mining height working face.

[0028] Third, by adding a double pedestrian passage layer, it is more conducive to the maintenance of the upper structural parts, cylinders and hydraulic systems of the support. At the same time, a connecting plate can be used on the second pedestrian passage layer to directly reach the coal shearer, which is more conducive to the maintenance of the coal shearer and improves the safety of maintenance.

[0054] The pedestrian passage module 10 provided by the embodiment of the present application includes a base 100, a group of columns 101, a first pedestrian passage layer 102, a second pedestrian passage layer 105 and a walking and climbing assembly 103. Among them, a group of columns 101 are arranged on the base 100, the first pedestrian passage layer 102 is arranged on the base 100, the first pedestrian passage layer 102 is used for staff to stand and walk, the second pedestrian passage layer 105 is rotatably connected to a group of columns 101, the second pedestrian passage layer 105 is arranged above the first pedestrian passage layer 102, and the second pedestrian passage layer 105 is used to rotate relative to a group of columns 101 to form a platform for staff to stand and walk; the walking and climbing assembly 103 is arranged between a group of columns 101, and the walking and climbing assembly 103 is used for the staff on the first pedestrian passage layer 102 to transfer to the second pedestrian passage layer 105. The above-mentioned pedestrian passage module 10 is mainly applied to the ultra-high mining height hydraulic support 1 to solve the problem that due to the large mining height of the support (the mining height of the ultra-high mining height support is generally 8 meters to 10 meters), the workers at the first-floor pedestrian passage cannot clearly see the working states of the front shearer and scraper conveyor, so that the equipment cannot be effectively controlled.

[0055] It should be noted that the extra-high mining height hydraulic support 1 is a hydraulic support with an inherent name in the prior art. In the traditional extra-high mining height hydraulic support 1, only one layer of pedestrian passage is provided, and the height of the pedestrian passage is 1.3 meters. Adding the height of the operator, which is 1.75 meters, the effective height space that can be observed by people is 3.05 meters. When the mining height of the working face reaches more than 6 meters, people cannot effectively observe and operate the working face conditions, and it is impossible to ensure the normal and efficient production of the extra-high mining height working face. At the same time, in the large mining height working state, it is impossible to effectively repair the upper part of the support.

[0056] The following specifically introduces the equipment layout of the large mining height working face: As Figure 1 shown, the working face uses a coal mining process for coal mining. A scraper conveyor 2 is arranged on the working face. The scraper conveyor 2 is arranged along the length of the working face, and a shearer 4 is arranged on the scraper conveyor 2. At the same time, an extra-high mining height hydraulic support 1 is arranged at the rear of the scraper conveyor. The extra-high mining height hydraulic support 1 and the scraper conveyor 2 are connected through connection points. The shearer 4 moves back and forth on the scraper conveyor 2 to cut coal. The cut coal falls on the scraper conveyor and is transported out through the scraper conveyor. After the coal is cut, the extra-high mining height hydraulic support 1 moves forward by one step distance, and then the scraper conveyor is pushed forward by one step distance, and then coal cutting is carried out to complete a cycle. Among them, in addition to providing forward power and supporting the roof, the extra-high mining height hydraulic support 1 also supports a safe operation space. The operator enters and exits the working face through the pedestrian passage 3 in the hydraulic support and performs the coal mining operation of the working face equipment.

[0057] In order to view the equipment status and coal cutting situation during the coal mining process. By setting a double pedestrian passage layer in the extra-high mining height support, the beneficial effects mainly include:

[0058] First, because the mining height of the extra-high mining height hydraulic support 1 is large, spalling is likely to occur. By setting a double pedestrian passage layer, the worker can work on the second pedestrian passage layer 105, which can avoid the harm caused by spalling to the staff, thereby improving the safety of the operation environment and ensuring the normal and efficient production of the large mining height working face.

[0059] Second, it can solve the problem that due to the large mining height of the support (the mining height of the extra-high mining height support is generally 8 meters to 10 meters), the worker cannot clearly see the working status of the front shearer and scraper conveyor at the first pedestrian passage layer 102, so that the equipment cannot be effectively controlled. By setting a double pedestrian passage layer, the equipment status and coal cutting situation can be viewed during the coal mining process, so as to facilitate the control of the equipment according to the actual situation, which is beneficial to ensuring the normal and efficient production of the large mining height working face.

[0060] Thirdly, by adding a double-layer pedestrian passage layer, it is more conducive to the maintenance of the upper structural components of the support, the oil cylinders and the hydraulic system. At the same time, on the second pedestrian passage layer 105, a connecting plate can be used to directly reach the shearer, which is more conducive to the maintenance of the shearer and improves the safety of maintenance.

[0061] In some embodiments, in order to facilitate the transfer of the staff on the first pedestrian passage layer 102 to the second pedestrian passage layer 105, the walking and climbing assembly 103 includes walking steps 1031 and a ladder 1032. Among them, the walking steps 1031 are arranged on the base 100, and the walking steps 1031 are fixedly connected between a group of columns 101. The walking steps 1031 are used for the staff on the first pedestrian passage layer 102 to reach a preset height; the ladder 1032 is arranged between a group of columns 101, and the ladder 1032 is used for the staff who reach the preset height to enter the second pedestrian passage layer 105.

[0062] It should be noted that the above-mentioned group of columns 101 specifically includes two columns 101, and the two columns 101 are arranged side by side on the base 100. Among them, the walking steps 1031 are arranged at the front of the first pedestrian passage layer 102, and the bottom of the walking steps 1031 is fixed to the base 100. The two sides of the walking steps 1031 are respectively fixedly connected to the inner walls of the two columns 101, and the ladder 1032 is also fixedly connected between the two columns 101, and the ladder 1032 is located above the walking steps 1031.

[0063] In some embodiments, in order to facilitate the fixation of the ladder 1032, the walking and climbing assembly 103 further includes a fixed connection beam 1033. The fixed connection beam 1033 is fixedly connected between the two columns 101. The width of the fixed connection beam 1033 is set to 600 mm, and the ladder 1032 is arranged on the fixed connection beam 1033.

[0064] In some embodiments, in order to facilitate the rotation of the second pedestrian passage layer 105, the pedestrian passage module 10 further includes a rotation drive assembly 104. One end of the rotation drive assembly 104 is hinged to the fixed connection beam 1033, and the other end is hinged to the second pedestrian passage layer 105.

[0065] Specifically, the rotation drive assembly 104 is specifically a rotary oil cylinder assembly. The fixed end of the rotary oil cylinder assembly is hinged to the fixed connection beam 1033, and the movable end of the rotary oil cylinder assembly is hinged to the bottom of the second pedestrian passage layer 105. At the same time, the second pedestrian passage layer 105 is hinged to the fixed connection beam 1033.

[0066] It should be noted that the hinge in this embodiment is a rotational connection through a pin shaft.

[0067] More specifically, the second pedestrian passage layer 105 is provided with a first hinge seat 10511 and a set of second hinge seats 10512. The fixed connection beam 1033 is provided with a third hinge seat 10331 and a set of fourth hinge seats 10332. The first hinge seat 10511 is used for connecting the movable end of the rotary drive assembly 104. The third hinge seat 10331 is connected to the fixed end of the rotary drive assembly 104. A set of second hinge seats 10512 are respectively connected to a set of fourth hinge seats 10332. In this way, when the rotary drive assembly 104 extends, the second pedestrian passage layer 105 can be rotated relative to the fixed connection beam 1033. When the second pedestrian passage layer 105 tends to be horizontal, a working platform structure can be formed.

[0068] In some embodiments, in order to ensure the stability of the second pedestrian passage layer 105 after deployment, the pedestrian passage module 10 further includes a set of fixed connecting rods 106. The set of fixed connecting rods 106 are detachably connected between the second pedestrian passage layer 105 and a set of columns 101. The set of fixed connecting rods 106 are used to support the second pedestrian passage layer 105.

[0069] It can be understood that the above set of fixed connecting rods 106 includes two fixed connecting rods 106. The two ends of any one fixed connecting rod 106 are respectively connected to the column 101 and the second pedestrian passage layer 105.

[0070] In some embodiments, the second pedestrian passage layer 105 includes a flip guard plate 1051 at the bottom. The flip guard plate 1051 is provided with a set of first supports 10513. A set of columns 101 are provided with a set of second supports 1011. The set of first supports 10513 includes two first supports 10513. The set of second supports 1011 includes two second supports 1011. In this way, the two ends of one of the fixed connecting rods 106 are respectively connected to one of the first supports 10513 and one of the second supports 1011, and the two ends of the other fixed connecting rod 106 are respectively connected to the other first support 10513 and the other second support 1011.

[0071] When the flip guard plate 1051 is adjusted to a proper position, the fixed connecting rod 106 is connected to the flip guard plate 1051 and the column 101, so as to ensure the stability of the walking platform.

[0072] In some embodiments, the second pedestrian passage layer 105 further includes a lifting pedal 1053 and a lifting drive assembly 1052. Among them, the lifting pedal 1053 is arranged on the flip guard plate 1051, and the lifting drive assembly 1052 is arranged between the flip guard plate 1051 and the lifting pedal 1053. The lifting drive assembly 1052 is used to drive the lifting pedal 1053 to lift. Of course, the lifting drive assembly 1052 is specifically a lifting oil cylinder assembly.

[0073] In this way, a lifting pedal 1053 connected by a lifting oil cylinder assembly is provided on the flipping guard plate 1051. The lifting pedal 1053 can be lifted within the range of 300 mm to 800 mm. At the same time, a guardrail 10531 is provided on the lifting pedal 1053 to protect personnel during walking and operation.

[0074] The above-mentioned movable second pedestrian passage layer 105 can be arranged 2.3 meters above the first pedestrian passage layer 102. Since the second pedestrian passage layer 105 can be rotated and retracted, and the second pedestrian passage layer 105 is lower than the outer cylinder seat of the column 101, it does not affect the bracket being received in the lowest position, facilitating the transportation and installation of the ultra-high mining height support. When the ultra-high mining height support is installed in place, the second pedestrian passage layer 105 can be opened.

[0075] When the mining height of the support reaches more than 7 meters, the operator walks to the front of the fixed connection beam 1033 through the walking steps 1031, and then climbs onto the second pedestrian passage layer 105 through the ladder 1032 to carry out corresponding coal mining work on the second pedestrian passage layer 105.

[0076] An ultra-high mining height hydraulic support 1 provided by the present application includes the pedestrian passage module 10 described in the above specific embodiments; the number of bases 100, the number of groups of columns 101, the number of the second pedestrian passage layers 105 and their related connecting parts in the pedestrian passage module 10 can be set as required. In this embodiment, 150 are preferably set. 150 second pedestrian passage layers 105 can open the corresponding number as required, and can be opened synchronously or successively when opened. Other parts of the ultra-high mining height hydraulic support 1 can refer to the prior art and will not be elaborated herein.

[0077] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0078] The above has introduced in detail the ultra-high mining height hydraulic support and its pedestrian passage module provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the solution and its core idea of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
