Description

Technical Field

[0001] This application relates to the technical field of slag chute tests, and particularly to a slag chute test platform. Background Art

[0002] The shaft is an indispensable part of various underground projects and plays a crucial role in coal development, metal mines, water conservancy and hydropower, and civil air defense projects. It is an important passage for humans to march deep into the earth. Therefore, the construction methods and related technologies of shaft tunneling have been widely explored. To enable the staff to "drill the well without going down the well" during the shaft tunneling construction process, reduce the safety hazards brought by the traditional shaft tunneling construction method, and ensure the safety of the construction personnel during the operation, the construction technology of the full-face shaft tunneling machine has been widely applied. However, there is a problem of anti-gravity slag discharge during the slag discharge process of the full-face shaft tunneling machine, and the rock slag is easily accumulated at the bottom of the excavation surface, resulting in secondary crushing, which seriously affects the construction efficiency and damages the cutter head structure.

[0003] To solve this engineering problem, industry insiders conduct tests to study the migration law of rock slag on the excavation surface with different engineering parameters during shaft tunneling in order to formulate corresponding countermeasures. However, the traditional test method cannot restore the engineering situation on the shaft site, and it is also difficult to process the data results of a large amount of rock slag generated at the tunneling site. There are problems such as inconvenient statistics of rock slag migration indicators, difficult control of influencing factors, time-consuming and laborious, etc., which greatly affect the correctness of the test conclusion.

Detailed implementation manners

[0019] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0021] Since the current slag chute test method cannot restore the engineering situation of the shaft site, and it is also difficult to process the data results of a large amount of rock slag generated at the tunneling site, there are problems such as inconvenient statistics of rock slag migration indicators, difficult control of influencing factors, time - consuming and laborious, etc., which greatly affect the correctness of the test conclusion. To solve the above problems, as Figure 1As shown in the figure, an embodiment of the present application provides a slag-sliding test platform 100, which may include a feeding device 10, a slag-sliding device 20, and a recovery device 30.

[0022] The feeding device 10 is used to supply rock slag. The rock slag as a test sample can be stored in the feeding device 10 to provide rock slag for the slag-sliding test according to the test needs. The rock slag can obtain corresponding rock slag samples according to the actual on-site geological conditions of coal development, metal mines, water conservancy and hydropower, civil air defense projects, etc., so that the test results are more in line with the actual construction conditions.

[0023] The slag-sliding device 20 receives the rock slag from the feeding device 10, and the slag-sliding device 20 is provided with a slag-sliding platform 21 for the rock slag to move. The inclination angle of the slag-sliding platform 21 relative to the horizontal plane can be adjusted within the range of 20° to 60°; the rock slag of the feeding device 10 can be transported to the slag-sliding device 20 by means of dropping or power transmission.

[0024] The inclination angle of the slag-sliding platform 21 configured by the slag-sliding device 20 relative to the horizontal plane can be adjusted. For example, the inclination angle of the slag-sliding platform 21 relative to the horizontal plane can be adjusted within the range of 0° to 90°, or according to the actual use requirements of the construction site working conditions, the inclination angle of the slag-sliding platform 21 relative to the horizontal plane can be adjusted within the range of 20° to 60°. During the process of the rock slag moving on the slag-sliding platform 21, the test personnel can observe and record the displacement, speed, retention situation, etc. of the rock slag. By obtaining the rock slag movement results at multiple different inclination angles in the test, the variable control in the test process can be made more clear and accurate, providing a data basis for analyzing the movement law of the rock slag, thereby facilitating improving the accuracy and reliability of the test conclusion.

[0025] The recovery device 30 is used to recover the rock slag transported by the slag-sliding platform 21. The rock slag recovered by the recovery device 30 can be weighed and measured, and compared with the weight of the rock slag before it moves on the slag-sliding platform 21 to analyze the retention situation of the rock slag during the movement on the slag-sliding platform 21. In addition, the rock slag recovered by the recovery device 30 can be reused for the slag-sliding test.

[0026] The slag-sliding test platform 100 provided by the embodiment of the present application includes a feeding device 10, a slag-sliding device 20, and a recovery device 30; the feeding device 10 is used to supply rock slag; the slag-sliding device 20 receives the rock slag from the feeding device 10, and the slag-sliding device 20 is provided with a slag-sliding platform 21 for the rock slag to move, and the inclination angle of the slag-sliding platform 21 relative to the horizontal plane can be adjusted within the range of 20° to 60°; the recovery device 30 is used to recover the rock slag transported by the slag-sliding platform 21. This slag-sliding test platform 100 can make the variable control in the test process more clear, the data statistics more convenient, and the test conclusion more accurate.

[0027] Optionally, in an embodiment of the present application, the feeding device 10 includes a slag storage bin 11, a pre-treatment bin 12, and a waiting test bin 13.

[0028] As Figure 2 shown, the slag storage bin 11 is of a box structure. The top of the slag storage bin 11 is provided with a top plate 110 that can be opened and closed, and the bottom of the slag storage bin 11 is provided with a bottom plate that can be opened and closed. The top plate 110 is rotatably connected to the top of the slag storage bin 11 to facilitate putting the rock slag for the test into the cavity of the slag storage bin 11. A pin shaft can be arranged at the top of the slag storage bin 11 to fix or open the top plate 110. The bottom plate is rotatably connected to the bottom of the slag storage bin 11 to facilitate the rock slag to flow out from the cavity of the slag storage bin 11 and supply it to the slag chute device 20. Similarly, a locking device such as a pin shaft can also be arranged to fix or open the bottom plate.

[0029] The pre-treatment bin 12 is located below the slag storage bin 11. As Figure 3 shown, the pre-treatment bin 12 includes a plurality of pre-screening units 120 arranged vertically. As Figure 4 shown, the pre-screening unit 120 includes a pre-screening support frame 121, a pre-screening plate 122, a pre-screening vibration device 123, and a movement control device 124. There is a passing space above the pre-screening support frame 121 that can allow the pre-screening plate 122 to extend in from one side and out from the other side. The pre-screening plate 122 is detachably connected to the pre-screening support frame 121, and the pre-screening plate 122 has sieve holes with a preset shape and size. The pre-screening vibration device 123 is located below the pre-screening support frame 121 to drive the pre-screening support frame 121 to drive the pre-screening plate 122 to vibrate. The movement control device 124 is detachably connected to the pre-screening plate 122 and is movably connected to the pre-screening support frame 121 to be able to drive the pre-screening plate 122 to extend out from the pre-screening support frame 121 and be able to tilt relative to the pre-screening support frame 121.

[0030] The pre-treatment bin 12 can be fixed to the ground through columns, and each pre-screening unit 120 can be connected and fixed through three rows of rear struts (not shown in the figure). The overall structure of the pre-treatment bin 12 can be a hollow cuboid structure, and the hollow part forms a falling and screening channel for rock slag. Specifically, the pre-treatment bin 12 can include a plurality of pre-screening units 120 arranged vertically, and a passing space can be reserved at the upper part of each pre-screening unit 120 to provide a moving channel for the pre-screening plate 122. The pre-screening support frame 121 can be a rectangular frame structure surrounded by a frame. A chute can be provided on one side of the pre-screening support frame 121, and a notch can be provided on the opposite side. The movement control device 124 is movably connected to the pre-screening support frame 121 so as to be able to slide along the chute. In this way, the movement control device 124 can drive the pre-screening plate 122 to be inserted from one side of the pre-screening unit 120, and then the pre-screening plate 122 can be fixed to the pre-screening support frame 121; the movement control device 124 can also drive the pre-screening plate 122 to be pushed out from the other side of the pre-screening unit 120, and then the movement control device 124 can be lifted upward so that the rock slag on the pre-screening plate 122 falls into the waiting test bin 13; in addition, a rod body can be passed through between the movement control device 124 and the pre-screening plate 122 or a detachable connection can be achieved by using bolts or the like, and this embodiment does not limit this.

[0031] Each pre-screening unit 120 can include a plurality of pre-screening vibration devices 123, such as 4, which are respectively located below the pre-screening support frame 121. As Figure 5 shown, the pre-screening vibration device 123 can be connected to the bottom surface of the pre-screening support frame through bolts. The pre-screening vibration device 123 can adopt a telescopic structure with a piston 1230. The pre-screening vibration device 123 can be connected to the vibration air pump 128. Before the test state, the piston 1230 of the pre-screening vibration device 123 does not contact the lower surface of the pre-screening support frame 121. During the test process, through the regular intermittent burst air supply of the vibration air pump 128, the air pressure in the piston 1230 of the pre-screening support frame 121 periodically increases and decreases greatly. Under this action, the piston 1230 will continuously move up and down greatly, and then continuously impact the lower surface of the pre-screening support frame 121 to drive the pre-screening support frame 121 to drive the pre-screening plate 122 to vibrate, so as to screen the rock slag.

[0032] The pre-screening plate 122 has sieve holes with a preset shape and size, and can be specifically divided into such as Figure 6 、 Figure 7The shown shape parameter sieve plate 122A and slag block size sieve plate 122B. The shape parameter sieve plate 122A can screen the slag test samples in terms of shape parameters. In the pretreatment bin 12, various shape parameter sieve plates 122A can be inserted to screen different slag shapes and conduct migration tests on slag with different shapes. The aperture size parameters of the sieve holes on each shape parameter sieve plate 122A are the same, so that the sieved slag is consistent in particle size, thus ensuring the consistency of the particle size distribution of the slag samples in the migration tests related to the shape parameters of the slag. The slag block size sieve plate 122B can screen the slag test samples in terms of slag block size. In the pretreatment bin 12, various slag block size sieve plates 122B can be inserted to screen different slag block sizes and conduct migration tests on slag with different block sizes. The aperture shape parameters on one block size sieve plate are the same, so that the sieved slag is consistent in shape, thus ensuring the consistency of the particle size and shape distribution of the slag samples in the migration tests related to the slag block size.

[0033] During the test, the slag falling from the slag storage bin 11 into the pretreatment bin 12 is vibrated and screened by the pre-screening unit 120 of the pretreatment bin 12. The slag with different particle sizes and shapes is respectively screened on the corresponding pre-sieve plates 122. Then, the slag with the corresponding particle size and shape screened by a certain pre-sieve plate 122 can be sent to the waiting test bin 13 for a slag flow test, or the slag with various particle sizes and shapes screened by several pre-sieve plates 122 can be sent to the waiting test bin 13 for a slag flow test, thereby improving the flexibility and convenience of the test.

[0034] The waiting test bin 13 is arranged adjacent to the pretreatment bin 12. As Figure 8 shown, the waiting test bin 13 and the pretreatment bin 12 can be detachably connected by a connecting piece or connected and fixed by welding. The waiting test bin 13 includes a plurality of annular frames 130 arranged vertically. Above the annular frame 130, there is a passage space on the side close to the pretreatment bin 12 that can allow the pre-sieve plate 122 to extend in. Among them, a discharge plate 131 that can be opened and closed is provided at the bottom of the waiting test bin 13.

[0035] The annular frame 130 can also be a rectangular frame structure surrounded by a border. Each annular frame 130 corresponds to a pre-screening support frame 121, so that the pre-screening plate 122 of each pre-screening support frame 121 extends into the upper part of the corresponding annular frame 130. After the movement control device 124 is lifted upward, the slag on the pre-screening plate 122 falls into the waiting test bin 13 from the corresponding annular frame 130. For example, the pre-treatment bin 12 may include 10 pre-screening units 120 and corresponding 10 pre-screening support frames 121, and the waiting test bin 13 may include 10 annular frames 130. In addition, pre-screening support frames 121 can be added at the bottom or top of the pre-treatment bin 12, and annular frames 130 can be added at the bottom or top of the waiting test bin 13 to facilitate the arrangement of related components and improve the overall strength of the structure.

[0036] Optionally, in an embodiment of the present application, as Figure 4 shown, the movement control device 124 includes a plate member 1241 and a rod member 1242. The plate member 1241 is detachably connected to the pre-screening plate 122 and movably connected to the pre-screening support frame 121; the rod member 1242 is connected to the plate member 1241; the pre-treatment bin 12 is further provided with a linkage rod 125, and one end of the rod member 1242 is detachably connected to the linkage rod 125. The plate member 1241 is detachably connected to the pre-screening plate 122 to drive the pre-screening plate 122 to move to the corresponding position and disengage from the pre-screening plate 122 when the pre-screening plate 122 needs to vibrate and screen the slag; the plate member 1241 is movably connected to the pre-screening support frame 121 to drive the pre-screening plate 122 to insert or pull out and be able to be lifted upward. The rod member 1242 is connected to the plate member 1241 and is detachably connected to the linkage rod 125. In this way, each pre-screening unit 120 can drive the plate member 1241 through the rod member 1242 to push the corresponding pre-screening plate 122 into the waiting test bin 13 for blanking, or the rod members 1242 of several pre-screening units 120 can be connected through the linkage rod 125 to push the pre-screening plates 122 of these several pre-screening units 120 into the waiting test bin 13 for blanking, thereby improving the convenience and flexibility of the test.

[0037] Optionally, in an embodiment of the present application, as Figure 9 shown, a pre-screening plate connecting member 1210 is provided on the pre-screening support frame 121. The pre-screening plate connecting member 1210 includes a first rotating member 1211, a second rotating member 1212, an insertion shaft 1213, and a locking member 1214. The first rotating member 1211 is rotatably connected to the pre-screening support frame 121; the second rotating member 1212 is rotatably connected to the first rotating member 1211; the insertion shaft 1213 passes through the second rotating member 1212 and can pass through the pre-screening support frame 121 and the pre-screening plate 122. The two ends of the insertion shaft 1213 are respectively provided with the locking members 1214 that can be threadedly connected to detachably connect the pre-screening plate 122 to the pre-screening support frame 121.

[0038] In this embodiment, the front sieve plate connecting member 1210 is used to achieve the detachable connection between the front sieve plate 122 and the front screening support frame 121. The first rotating member 1211 of the front sieve plate connecting member 1210 is rotatably connected to the front screening support frame 121, so that it can rotate around the first direction axis. The second rotating member 1212 is rotatably connected to the first rotating member 1211, so that it can rotate around the second direction axis, improving the degree of freedom of movement and the convenience of use of the front sieve plate connecting member 1210. Align the connection holes opened on the front sieve plate 122 and the connection holes opened on the front screening support frame 121 respectively, and then the first rotating member 1211 and the second rotating member 1212 can be rotated to appropriate positions so that the insertion shaft 1213 can pass through the connection holes of the front screening support frame 121 and the connection holes of the front sieve plate 122. Furthermore, the locking members 1214 at both ends of the insertion shaft 1213, such as wing nuts, etc., can be locked, so that the front sieve plate 122 is fixed to the front screening support frame 121 for vibrating and screening the rock slag conveniently.

[0039] Optionally, in an embodiment of the present application, a plurality of dyeing devices 126 are further provided on one side of the front treatment bin 12 close to the waiting test bin 13. Each dyeing device 126 corresponds to each front screening unit 120 respectively to spray paint and dye the rock slag after screening by the front screening unit 120. Among them, the front treatment bin 12 is provided with a dyeing air pump 127. The dyeing device 126 has an accommodation cavity and is provided with a plurality of spray ports 1260. The accommodation cavity is configured with paint of a preset color. The dyeing air pump 127 is connected to the air inlet of the accommodation cavity to pressurize the accommodation cavity by using the dyeing air pump 127 so that the paint is sprayed out from the spray ports 1260. As Figure 10 shown, each dyeing device 126 can be provided with a plurality of spray holes, and different colors of paint are contained in the accommodation cavity of each dyeing device 126. It can be understood that the rock slag screened out by each front screening unit 120 is dyed different colors respectively, which is convenient to observe the migration situation of the rock slag with corresponding particle sizes and shapes during the process of discharging the slag, thus improving the convenience of the test.

[0040] Optionally, in an embodiment of the present application, as Figure 11 、 Figure 12As shown in the figure, the slag chute device 20 further includes a front support frame 22 and a rear support frame 23. The first end of the slag chute table 21 is located below the feeding device 10 and is rotatably connected to the front support frame 22. A winding wheel 231 is provided at the lower part of the rear support frame 23, and a fixed pulley 232 is provided at the upper part of the rear support frame 23. A lifting rope 233 is wound around the winding wheel 231, and one end of the lifting rope 233 is connected to the second end of the slag chute table 21 after passing around the fixed pulley 232. A moving wheel 234 is further provided at the bottom of the rear support frame 23 so that the relative distance between the rear support frame 23 and the front support frame 22 can be adjusted. The moving wheel 234 can be attached with a braking function, for example, using a caster with a braking device, so that the rear support frame 23 can be stabilized on the ground after the distance adjustment is completed. The front support frame 22 is used to support the first end of the slag chute table 21 and is rotatably connected to the first end of the slag chute table 21. In this way, by rotating the winding wheel 231 on the rear support frame 23, under the action of the fixed pulley 232, the second end of the slag chute table 21 can be raised or lowered, so that the inclination angle of the slag chute table 21 can be adjusted. In this way, during the test process, according to the test requirements, by adjusting the relative height of the second end of the low slag chute table 21, the parametric adjustment ability of the inclination angle of the slag chute table 21 relative to the horizontal plane can be realized. During the process of adjusting the inclination angle of the slag chute table 21, the horizontal distance between the second end of the slag chute table 21 and the rear support frame 23 will change. Therefore, in this embodiment, a moving wheel 234 is further provided at the bottom of the rear support frame 23 so that the relative distance between the rear support frame 23 and the front support frame 22 can be adjusted, that is, the horizontal distance between the rear support frame 23 and the second end of the slag chute table 21 can be adjusted.

[0041] Optionally, in an embodiment of the present application, as Figure 11As shown in the figure, a slag chute belt 210 capable of adhering to muck is provided on the slag chute platform 21. A first winding shaft 211 is provided at the first end of the slag chute platform 21, and second winding shafts 212 are respectively provided at the second end of the slag chute platform 21. Both ends of the slag chute belt 210 are respectively wound around the first winding shaft 211 and the second winding shaft 212. Among them, a plurality of telescopic devices 213 are further provided below the slag chute belt 210 on the slag chute platform 21 so that the slag chute belt 210 can form a undulating state. Specifically, the slag chute belt 210 can be made of a polymer organic material. The width of the slag chute belt 210 can be smaller than that of the slag chute platform 21, and the length can be greater than that of the slag chute platform 21. The excess length is respectively wound into the first winding shaft 211 at the first end of the slag chute platform 21 and the second winding shaft 212 at the second end of the slag chute platform 21. Rocking rods can be respectively arranged on the first winding shaft 211 and the second winding shaft 212 to drive the slag chute belt 210 to roll, so as to release an appropriate length of the slag chute belt 210 or retract an appropriate length of the slag chute belt 210. The slag chute belt 210 can adhere to muck with the mechanical parameters of the excavation face material to study the influence of the muck with the mechanical parameters of the excavation face material on the rock slag transportation. In this embodiment, the slag chute belt 210 is 2.5 m long, 1.5 m wide, and 30 cm thick. A number of telescopic devices 213 are distributed under the slag chute belt 210. The slag chute platform 21 can be configured with a support frame with a suitable shape to install the slag chute belt 210 and the telescopic devices 213. The telescopic devices 213 can adopt a plurality of cylinders with different preset telescopic lengths, or cylinders with adjustable telescopic lengths. In some embodiments, the telescopic devices 213 can also adopt components with higher adjustment accuracy such as linear motors or lead screws. By the up and down telescoping of these telescopic devices 213 to form a preset height, the slag chute belt 210 undergoes different degrees of undulation, and a corresponding uneven rock slag transportation surface can be formed. In this way, by adjusting the telescopic lengths of the plurality of telescopic devices 213, the unevenness of the slag chute belt 210 can be adjusted, thereby improving the control and simulation ability of variables during the test and making the test conclusion more accurate.

[0042] The first winding shaft 211 and the second winding shaft 212 are respectively rotatably connected to the first end and the second end of the slag chute 21. For example, bearing seats can be respectively arranged on both sides of the first end of the slag chute 21. The bearing seats can be connected to the slag chute 21 by bolts. Bearings are arranged inside the bearing seats. Both ends of the first winding shaft 211 are respectively inserted into the bearings. Under the action of the bearings, the first winding shaft 211 can rotate relative to the first end of the slag chute 21. A rocker can be arranged at one end of the first winding shaft 211 for easy rotation operation. A locking device such as a brake or a locking nut can be arranged at the other end of the first winding shaft 211. For example, when the first winding shaft 211 drives the slag chute belt 210 to rotate to a preset length, the locking nut can be tightened to abut against the end face of the bearing seat. The locking nut and the end face of the bearing seat respectively have friction surfaces at the abutting parts. In this way, a pre-tightening force can be generated between the other end of the first winding shaft 211 and the bearing seat. And under the action of this pre-tightening force, the other end of the first winding shaft 211 and the bearing seat are locked due to the frictional torque, so as to prevent the first winding shaft 211 and the slag chute belt 210 from slipping. Similarly, the second winding shaft 212 and the second end of the slag chute 21 can also adopt the above device to realize the rotational connection and prevent slipping.

The longitudinal displacement scale 24, the transverse displacement scale 25, and the vertical displacement scale 26 in this embodiment can respectively emit lasers, which is convenient for observing the displacement of the rock slag in the corresponding direction and will not cause any influence on the movement of the rock slag. For example, scales can be marked every 5 cm on the longitudinal displacement scale 24, the transverse displacement scale 25, and the vertical displacement scale 26 respectively, and laser emitting elements are arranged at these scales. It can be understood that the arrangement of the displacement scales and the laser emitting elements further improves the convenience of test observation and recording, and is beneficial to obtaining more accurate observation results of the rock slag migration.
