Description

Technical Field

[0001] This utility model relates to the field of coal support technology, specifically a coal support with auxiliary coal transportation function. Background Technology

[0002] Coal mining hydraulic supports are structures used to control mine pressure at coal faces. A hydraulic support consists of hydraulic cylinders (columns, jacks), load-bearing structural components (top beams, shield beams, and bases, etc.), a pushing device, a control system, and other auxiliary devices. Its operating principle is as follows:

[0003] The supports are supplied with emulsion pumps installed in the roadway or chamber. When the pressurized emulsion enters the column through the control system, the support rises to initially support the roof. As the roof sinks, the support resistance to the roof increases. The pressure of the liquid locked in the column is limited by a safety valve to achieve constant resistance support. When moving the support, the column is first lowered to unload the support and detach it from the roof. Then, the jacks are moved to move the support using the conveyor (or adjacent supports, etc.) as a fulcrum. The support is then moved again using the supported support as a fulcrum. The support can also perform various auxiliary actions such as side protection, balancing, and adjustment using various jacks, thereby cooperating with the coal mining machine and scraper conveyor to achieve comprehensive mechanization of coal cutting, support, and transportation at the working face. The hydraulic supports are arranged at certain intervals at the working face, mostly moving sequentially, but a few also use segmented or alternating movement.

[0004] In the actual use of coal hydraulic supports, during mining and tunneling, there are large pieces of coal. These large pieces of coal are prone to rolling off the conveyor belt due to inertia and are likely to collide with the hydraulic cylinder area of ​​the coal hydraulic support, affecting the safety and lifespan of the coal hydraulic support. Based on this, a coal support with auxiliary coal transportation is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a coal support with auxiliary coal transportation in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coal support with auxiliary coal transportation, comprising a support assembly consisting of a base, connecting rod, movable side guard plate, hydraulic column, top beam, front side guard device, and pushing device. A storage groove is provided in the middle of the top of the base, and a baffle assembly extending to the top and front of the base is provided on the inner side of the storage groove. The unfolded baffle assembly is used to protect the front of the support assembly.

[0007] The material blocking assembly includes a tilting arm, a material blocking plate, and a driving hydraulic cylinder;

[0008] The tilting arm is rotatably connected to the inner front end of the receiving trough, and the tilting arm extends and protrudes to the front end of the base. The baffle plate is fixed to the front end of the tilting arm. The tail end of the driving hydraulic cylinder is rotatably connected to the inner rear end of the receiving trough. The front end of the output end of the driving hydraulic cylinder is rotatably connected to the rear end face of the baffle plate, which is used to provide support for the vertical state of the baffle plate. The vertical baffle plate is used to intercept large pieces of coal rolling off the conveyor belt.

[0009] As a further embodiment of this utility model: the movable side guard plate is rotatably connected to the rear end of the base via a connecting rod, the top beam is rotatably connected to the front end of the movable side guard plate, the bottom of the hydraulic column is rotatably connected to the base, and the top of the output end of the hydraulic column is rotatably connected to the lower surface of the top beam.

[0010] The front-end support device is movably installed at the front end of the top beam, and the pushing device is installed on the inner side of the middle of the bottom of the base.

[0011] As a further improvement of this utility model: multiple hydraulic columns are provided, and the multiple hydraulic columns are symmetrically divided into two groups with the receiving groove as the center. The width of the baffle plate is smaller than the distribution distance between the two groups of hydraulic columns.

[0012] As a further improvement of this utility model: when the flipping arm is in a horizontal state, the lower surface of the flipping arm is in contact with the bottom of the inner wall of the storage groove.

[0013] As a further improvement of this utility model: when the flipping arm is in a horizontal state, the baffle plate is in an inclined vertical state, and the upward tilting direction is towards the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a baffle assembly, when a large piece of coal rolls onto the conveyor belt and continues to roll outwards due to excessive inertia, the vertical baffle plate can intercept the large piece of coal. This not only prevents the large piece of coal from rolling off the conveyor belt, but also prevents it from impacting or damaging the hydraulic column. Attached Figure Description

[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 Figures 1-3 In this embodiment of the utility model, a coal support with auxiliary coal transportation includes a support assembly 1 consisting of a base 101, a connecting rod 102, a movable side guard plate 103, a hydraulic column 104, a top beam 105, a front side protection device 106, and a pushing device 107. The movable side guard plate 103 is rotatably connected to the rear end of the base 101 via the connecting rod 102. The top beam 105 is rotatably connected to the front end of the movable side guard plate 103. The bottom of the hydraulic column 104 is rotatably connected to the base 101. The top end of the output end of the hydraulic column 104 is rotatably connected to the lower surface of the top beam 105. The front side protection device 106 is movably installed at the front end of the top beam 105. The pushing device 107 is installed on the inner side of the middle of the bottom of the base 101.

[0022] A storage slot 108 is provided in the middle of the top of the base 101. A baffle assembly 2 extending to the top and front of the base 101 is provided on the inner side of the storage slot 108. The unfolded baffle assembly 2 is used to protect the front of the bracket assembly 1.

[0023] The material blocking assembly 2 includes a tilting arm 201, a material blocking plate 202, and a drive hydraulic cylinder 203;

[0024] The tilting arm 201 is rotatably connected to the inner front end of the receiving trough 108, and the tilting arm 201 extends and protrudes to the front end of the base 101. The baffle plate 202 is fixed to the front end of the tilting arm 201. The tail end of the driving hydraulic cylinder 203 is rotatably connected to the inner rear end of the receiving trough 108. The front end of the output end of the driving hydraulic cylinder 203 is rotatably connected to the rear end face of the baffle plate 202, which is used to provide support for the vertical state of the baffle plate 202. The vertical baffle plate 202 is used to intercept large pieces of coal rolling off the conveyor belt.

[0025] In this embodiment, it should be noted that the support assembly 1 is based on the ZZ4000 / 12 / 24 type coal mine hydraulic support and its working principle is the same as that of the ZZ4000 / 12 / 24 type coal mine hydraulic support. The front-end support device 106 and the pushing device 107 are also conventional structures of existing coal mine hydraulic supports. Therefore, the structural details and working principle of the front-end support device 106 and the pushing device 107 will not be elaborated here.

[0026] When this support assembly 1 is in use, by activating the drive hydraulic cylinder 203, the baffle plate 202 and the tilting arm 201 are tilted towards the front of the base 101 with the rotating connection between the tilting arm 201 and the receiving trough 108 as the center, so that the baffle plate 202 is in an upright state (it should be noted that: the front end of the support assembly 1 is covered with a conveyor belt for transporting the mined coal). The upright baffle plate 202 is close to the side plate of the conveyor belt. In this way, during the mining process, when a large piece of coal rolls onto the conveyor belt and has too much inertia, it continues to roll outward of the conveyor belt (i.e. towards the support assembly 1). The upright baffle plate 202 can intercept this large piece of coal, which not only prevents the large piece of coal from rolling out of the conveyor belt, but also prevents the large piece of coal from impacting and damaging the hydraulic column 104.

[0027] Please refer to this carefully. Figures 1-3 Multiple hydraulic columns 104 are provided, and the multiple hydraulic columns 104 are symmetrically divided into two groups with the receiving groove 108 as the center. The width of the baffle plate 202 is smaller than the distribution spacing between the two groups of hydraulic columns 104.

[0028] In this embodiment: this structure ensures that the flipping operation of the baffle plate 202 will not interfere with the hydraulic column 104;

[0029] It should also be noted that before the baffle plate 202 unfolds from the retracted state to the upright state, the hydraulic column 104 first operates to lift the top beam 105, so as not to affect the flipping of the baffle plate 202, and before the top beam 105 moves down to be retracted, the baffle plate 202 is flipped to the retracted state.

[0030] Please refer to this carefully. Figures 1-3 When the flip arm 201 is in a horizontal state, the lower surface of the flip arm 201 is in contact with the bottom of the inner wall of the storage groove 108.

[0031] When the tilting arm 201 is in a horizontal state, the baffle plate 202 is tilted vertically and tilted upward toward the base 101.

[0032] In this embodiment: the horizontally positioned flipping arm 201 is attached to the bottom of the inner wall of the receiving trough 108 to determine the flipping angle of the baffle plate 202. Through the inclined distribution of the baffle plate 202, the inclined surface of the baffle plate 202 allows large pieces of coal to roll upward a short distance along the inclined outer wall under inertia before falling back onto the conveyor belt, thereby reducing the hard impact between the rolling large pieces of coal and the baffle plate 202.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
