Description

Technical Field

[0001] The present invention belongs to the technical field of test and detection, and more particularly, relates to a test device. Background Art

[0002] The demand for intelligent integrated anchor support products is increasing continuously, and automated systems are used to replace manual operations. Therefore, while developing intelligent anchor support system products, building a test bench for intelligent anchor support systems can effectively detect the anchoring performance. However, in related technologies, the devices for anchoring performance tests often cannot simulate real working scenarios and cannot reach real stress states, thus affecting the accuracy of experiments. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a test device, which includes: a bracket; a first test seat disposed on the bracket and used for setting a first test piece to be measured; a second test seat disposed on the bracket and used for setting a second test piece to be measured; and a drilling device for drilling holes in the first test piece to be measured and the second test piece to be measured.

[0005] The test device provided by the present invention includes a bracket, on which a first test seat and a second test seat are disposed. A first test piece to be measured is disposed in the first test seat, and the drilling device can perform drilling operations on the first test piece to be measured in the first test seat. A second test piece to be measured is disposed in the second test seat, and the drilling device can perform drilling operations on the second test piece to be measured in the second test seat.

[0006] In actual anchoring work, it is necessary to drill holes in the top and side walls of a roadway and insert anchor bolts into the holes to improve the stability of the roadway. The test device in this application can be used for simulation tests of roadway anchoring. By performing drilling operations on the first test piece to be measured and the second test piece to be measured, a real roadway structure can be simulated. Specifically, the first test seat can be disposed at the upper part, and the second test seat can be disposed at the side part. The first test piece to be measured can simulate the top anchor test, and the second test piece to be measured can simulate the side anchor test to achieve simulating the real stress state of roadway anchoring.

[0007] In addition, according to the test device provided by the above technical solution of the present invention, the following additional technical features are further provided:

[0008] In a possible design, the drilling device can drill holes in the first test piece along a first direction; the drilling device can also drill holes in the second test piece along a second direction; the first direction is different from the second direction.

[0009] In this design, the punching device can perform a punching operation on the first test piece along the first direction. Specifically, the first direction can be the vertically upward direction. That is to say, through the punching device, the first test piece is punched from bottom to top, so as to simulate the roof bolt test in the actual working condition.

[0010] The punching device can also perform a punching operation on the second test piece along the second direction. Specifically, the second direction is the horizontal direction or a direction with a certain inclination angle to the horizontal. Through the punching device, the second test piece is punched from right to left, so as to simulate the side bolt test in the actual working condition. When the second direction is a direction with a certain angle to the horizontal direction, the value range of the angle is within the range of 1° to 10°. For example, the angle can be selected as 5°, or 8°, or 10°. Specifically, when the angle value is 8°, better punching and anchoring effects can be achieved. The actual inclination angle can be adaptively adjusted according to the size of the second test piece and the actual simulated working condition.

[0011] In a possible design, the first test seat is provided with a first partition board, and the first partition board is arranged in a cross shape.

[0012] In this design, a first partition board is arranged at the bottom of the first test seat, and the first partition board is arranged in a cross shape. Specifically, through the cross-shaped first partition board, the bearing capacity of the first test seat can be improved. The first partition board can be made of steel plate, and the cross arrangement of the steel plates can make the bottom of the first test seat have better bearing capacity.

[0013] In a possible design, the punching device can perform a punching operation along the first direction into the cross space of the first partition board.

[0014] In this design, there is a cross-shaped first partition board at the bottom of the first test seat. It can be understood that to simulate the real roof bolt test, a punching operation needs to be performed on the first test piece. Since the first partition board is cross-arranged at the bottom of the first test seat, to avoid the punching device punching on the first partition board and affecting the test effect, the punching operation is avoided on the first partition board and is performed in the cross space of the cross-shaped first partition board, so as to ensure the test effect of the roof bolt test on the first test piece.

[0015] In a possible design, the first test seat further includes a sandwich layer, and the partition board is arranged in the sandwich layer; the sandwich layer is used to carry the first test piece.

[0016] In this design, the first test seat is also provided with a mezzanine, wherein the first partition is arranged inside the mezzanine, that is, the mezzanine wraps the first partition. It can be understood that after installing the cross-arranged first partition, the interlayer can be set up by pouring concrete, and the first test piece can be placed on the interlayer, so that the bearing capacity of the first test seat can be improved through the interlayer, and a reliable and flat placement platform is provided for the first test seat, so that the first test piece can be stably placed in the first test seat, thereby ensuring the subsequent punching effect.

[0017] In a possible design, the test device further includes a first limiter, which is disposed on the bracket and is disposed away from the first test seat along the first direction; the first limiter is used to limit the displacement of the first test piece along the first direction.

[0018] In this design, the test device is also provided with a first limit member, which is arranged on the bracket and at one end away from the first test seat, wherein one end of the first limit member is connected to the bracket, and the other end is against the first test piece. In the process of the punching device punching the first test piece, the force direction of the first test piece is from bottom to top, so that the first test piece will produce an upward displacement. By arranging the first limit member on the bracket, the upward displacement of the first test piece is limited, which is conducive to better punching operation on the first test piece, thereby better simulating the top anchor test in actual working conditions.

[0019] Specifically, the first limiter is made of a hard material with a certain strength, such as a steel material or an iron material. The first limiter can be made of ordinary steel material, which can produce a limiting function for the first test piece and save the cost of the test device.

[0020] In a possible design, the second test seat is provided with a second partition plate, and the second partition plates are cross-arranged; the second test seat is also provided with a support plate, and the support plate is arranged on the second partition plate.

[0021] In this design, the second test seat is provided with a second partition, and specifically the second partition is arranged at the bottom of the second test seat. Specifically, the second test piece is arranged in the second test seat. In order to improve the carrying capacity of the second test seat, a cross-arranged partition is arranged at the bottom of the second test seat, and a support plate is arranged on the partition, and the second test piece is arranged on the support plate.

[0022] Specifically, the support plate can be made of an ordinary steel plate, which can provide a stable installation platform for the second test piece.

[0023] In a possible design, the test device further includes a second limiting member disposed on the bracket, and the second limiting member is arranged away from the punching device along the second direction; the second limiting member is used to limit the displacement of the second measuring member along the second direction.

[0024] In this design, the test device further includes a second limiting member, and the second limiting member is arranged away from the second test seat along the second direction. Specifically, during the punching operation of the second test piece by the punching device, the force direction of the second test piece is set from right to left, so that the second test piece will generate a leftward displacement. By arranging the second limiting member on the bracket on the left side of the second test piece, the leftward displacement generated by the second test piece is restricted, which is beneficial to better perform the punching operation on the second test piece, and thus better perform the simulation of the roof bolt test in the actual working condition.

[0025] In a possible design, the test device further includes a support seat for supporting the bracket.

[0026] In this design, the test device further includes a support seat. Specifically, a support seat is provided at the lower part of the bracket, and the support seat provides a supporting force for the bracket, thereby ensuring the stability of the bracket. When performing the punching operation on the first test piece and the second test piece, a real test effect can be simulated.

[0027] In a possible design, the bracket includes a connected support column and a support beam; the support column and the support beam are connected by welding.

[0028] In this design, the bracket includes a connected support column and a support beam, and the support column and the support beam are connected by welding. Specifically, the bracket may include a vertically arranged support column and a horizontally arranged support beam, and the support column and the support beam are welded together to ensure the stability of the bracket.

[0029] Specifically, the support column and the support beam can be made of hot-rolled H-beams, hot-rolled channel steels, and equal-leg angle steels.

Detailed implementation manners

[0043] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0044] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0045] The following refers to Figures 1 to 9 Describe a test device according to some embodiments of the present invention.

[0046] AsFigure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown in Figure 8 , an embodiment of the present invention provides a test device, including a bracket 110, a first test seat 120 disposed on the bracket 110, and the first test seat 120 is used for setting a first test piece 122; a second test seat 130 disposed on the bracket 110, and the second test seat 130 is used for setting a second test piece 132; a punching device for punching the first test piece 122 and the second test piece 132.

[0047] The test device provided by the present invention includes a bracket 110, on which a first test seat 120 and a second test seat 130 are provided. A first test piece 122 is disposed in the first test seat 120, and the punching device can perform a punching operation on the first test piece 122 in the first test seat 120. A second test piece 132 is disposed in the second test seat 130, and the punching device can perform a punching operation on the second test piece 132 in the second test seat 130.

[0048] In a specific embodiment, the test device can simulate the anchoring effect of bolt support on the top and side walls of a roadway. In actual anchoring work, it is necessary to punch holes in the top and side walls of the roadway and insert bolts into the holes to improve the stability of the roadway. In this embodiment, the test device can be used for the simulation test of roadway anchoring. By performing punching operations on the first test piece 122 and the second test piece 132, the real roadway structure can be simulated. Specifically, the first test seat 120 can be set at the upper part, and the second test seat 130 can be set at the side part. The first test piece 122 can simulate the top anchor test, and the second test piece 132 can simulate the side anchor test to realize the simulation of the real stress state of roadway anchoring.

[0049] Specifically, the punching device is disposed at the bottom of the first test seat 120 and on the right side of the second test seat 130, so as to better perform punching operations on the first test piece 122 and the second test piece 132. The punching position can be adjusted adaptively according to the actual punching method and the number of punches.

[0050] In a specific embodiment, the support 110 is made of steel structure, and the first test piece 122 and the second test piece 132 are concrete test blocks. The concrete test blocks with a certain hardness are used to simulate the hardness of rocks or coal in the roadway under actual working conditions. The concrete specification is C60, the Proctor hardness is f = 5 - 6, and the compressive strength of the hardness-simulated rock is 60 MPa, simulating the hardness of ore or coal to the greatest extent. By conducting drilling tests on the concrete test blocks with a certain hardness, the top bolt support operation, side bolt operation, and wire mesh hanging operation of the intelligent anchor support system can fully simulate the working scenarios in a real roadway.

[0051] Specifically, the first test piece 122 and the second test piece 132 made by concrete casting can be made into independent small test blocks without steel bars, and can be hoisted and stacked into the first test seat 120 and the second test seat 130. The concrete test blocks are modular and can be independently replaced.

[0052] In a specific embodiment, the first test piece 122 is used for top anchor tests to simulate the top anchor support operation in an actual roadway. Specifically, the first test piece 122 can be placed in the first test seat 120 in a three-layer stacking manner. The three-layer stacked first test pieces 122 can be 18 pieces, with the size of: 1300*850*720 mm. This method of stacking test blocks allows for quick replacement in case of damage to the concrete test blocks, with a high reuse rate of the support 110 and saving the development cycle.

[0053] Of course, the shape and structure of the first test piece 122 can be replaced by other shapes and structures. For example, the first test piece 122 can be designed as an independent modular concrete test block that can be integrally cast, or can be replaced by rocks with the same hardness. The specific shape and structure of the first test piece 122 are not unique, and the actual shape and structure of the first test piece 122 can be adaptively adjusted according to the actual working conditions and the size of the first test seat.

[0054] In a specific embodiment, the second test piece 132 is used for side anchor tests to simulate the side anchor support operation in an actual roadway. Specifically, the second test piece 132 can be placed in the second test seat 130 in a two-layer stacking manner. The two-layer stacked second test pieces 132 can be 16 pieces, and the 16 second test pieces 132 can be divided into two specifications. The first specification is 12 pieces, with the size of: 1000*550*700 mm, and the second specification is 4 pieces, with the size of: 1000*550*900 mm. This method of stacking test blocks allows for quick replacement in case of damage to the concrete test blocks, with a high reuse rate of the support 110 and saving the development cycle.

[0055] Of course, the second test piece 132 can be designed to be replaced by an integrally cast concrete test block that is independently modular, or it can be replaced by a rock of the same hardness. The specific shape and structure of the second test piece 132 are not unique, and the actual shape and structure of the second test piece 132 can be adaptively adjusted according to the actual working conditions and the size of the second test seat.

[0056] It should be noted that the first test seat 120 and the second test seat 130 are respectively used to place the first test piece 122 and the second test piece 132. Therefore, the first test seat 120 and the second test seat 130 have a certain load-bearing capacity. Specifically, the first test seat 120 and the second test seat 130 can withstand a vertical test load of 30 KN and a dynamic load of 2 kN / m, so as to better carry the first test piece 122 and the second test piece 132 and simulate the actual roadway conditions for the roof bolt test and the rib bolt test.

[0057] In a specific embodiment, by arranging the first test seat 120 and the second test seat 130 on the support 110, a three-dimensional roadway structure is truly built. By using a punching device to punch holes in the first test piece 122 and the second test piece 132, it can be used for products such as intelligent bolt support systems and roadheader-anchor support machines to conduct tests on the anchoring effects such as bolt support and mesh hanging on the roof and rib of the roadway. It can quickly and effectively verify the various functions of the intelligent bolt support system products in the laboratory.

[0058] In a specific embodiment, the net width of the support 110 is 3800 mm, the net height is 5700 mm, and the depth is 3250 mm, which can meet the requirements for conducting bolt support tests on the widest existing mainframe.

[0059] Among them Figure 2 is the plan layout diagram of the test device on the plane with an elevation of 2.38 m. Figure 3 is the plan layout diagram of the test device on the plane with an elevation of 4.19 m, where L1, L2, L3, A, B, and C represent the axes of the plan schematic diagram of the test device.

[0060] In the above embodiment, further, the punching device can punch holes in the first test piece along the first direction; the punching control device can also punch holes in the second test piece along the second direction; the first direction is different from the second direction.

[0061] In this embodiment, the punching device can perform a punching operation on the first test piece 122 along the first direction. Specifically, the first direction can be a vertically upward direction. That is to say, through the punching device, the first test piece 122 is punched from bottom to top, so as to simulate the roof bolt test under actual working conditions.

[0062] The punching device can also perform a punching operation on the second test piece 132 along the second direction. Specifically, the second direction is a horizontal direction or a direction inclined at a certain angle to the horizontal. Through the punching device, a punching operation is performed on the second test piece 132 from right to left, so as to simulate the rib anchor test in the actual working condition. When the second direction is a direction inclined at a certain angle to the horizontal direction, the value range of the angle is within the range of 1° to 10°. For example, the angle can be selected as 5°, or can be selected as 8°, or can also be selected as 10°. Specifically, when the angle value is 8°, better punching and anchoring effects can be achieved. The actual inclination angle can be adaptively adjusted according to the size of the second test piece 132 and the actual simulated working condition.

[0063] As Figure 5 and Figure 6 shown, the first test seat 120 is provided with a first partition 124, and the first partition 124 is arranged in a cross shape.

[0064] In this embodiment, a first partition 124 is provided at the bottom of the first test seat 120, and the first partition 124 is arranged in a cross shape. Specifically, through the cross-shaped first partition 124, the bearing capacity of the first test seat 120 can be improved. The first partition 124 can be made of a steel plate, and the cross arrangement of the steel plates can enable the bottom of the first test seat 120 to have better bearing capacity.

[0065] In a specific embodiment, the first partition 124 can be made of an I-beam. The I-beam is convenient for installation, can effectively improve the bearing capacity, and is convenient for procurement. While ensuring the bearing capacity, it also saves the production cost.

[0066] On the basis of the above embodiment, further, the punching device can perform a punching operation along the first direction into the cross space of the first partition 124.

[0067] In this embodiment, there is a first partition 124 arranged in a cross shape at the bottom of the first test seat 120. It can be understood that to simulate a real roof anchor test, a punching operation needs to be performed on the first test piece 122. Since the first partition 124 is arranged in a cross shape at the bottom of the first test seat 120, to avoid the punching device punching on the first partition 124 and affecting the test effect, the punching operation is avoided on the first partition 124, and the punching operation is performed in the cross space of the cross-shaped first partition 124, so as to ensure the test effect of the roof anchor test on the first test piece 122.

[0068] It is understandable that in actual tunnel conditions, most of the objects to be anchored are rocks or coal, which have a certain hardness but are essentially different from the material of the partition. The first test piece 122 is made of concrete material in order to simulate the actual hardness of real rocks or coal. Therefore, the drilling operation should be carried out avoiding the first partition 124 to simulate the actual tunnel structure.

[0069] like Figure 5 and Figure 6 As shown, the first test seat 120 further includes an interlayer 126 , and a partition is disposed in the interlayer 126 ; the interlayer 126 is used to carry the first DUT 122 .

[0070] In this embodiment, the first test seat 120 is further provided with an interlayer 126, wherein the first partition 124 is arranged inside the interlayer 126, that is, the interlayer 126 is wrapped around the first partition 124. It can be understood that after installing the cross-arranged first partitions 124, the interlayer 126 can be arranged by pouring concrete, and the first test piece 122 can be placed on the interlayer 126, so that the bearing capacity of the first test seat 120 can be improved through the interlayer 126, and a reliable and flat placement platform is provided for the first test seat 120, so that the first test piece 122 can be stably placed in the first test seat 120, thereby ensuring the subsequent punching effect.

[0071] In a specific embodiment, the interlayer 126 is cast with concrete. After the first partition 124 is installed, concrete is cast at the bottom of the first test seat 120, wherein the hardness of the concrete is the same as that of the first test piece 122, so as to avoid the different hardnesses affecting the experimental effect and ensure the flatness of the upper and lower parts of the interlayer 126. A hole is punched at the lower part of the interlayer 126, and the upper part of the interlayer 126 is used to carry the first test piece 122. During the punching process, the position of the first partition 124 is avoided, and holes are punched at the intersection space of the first partition 124, and the interlayer 126 is penetrated to directly act on the first test piece 122 placed on the upper part. When there are multiple first test pieces 122, they are placed on the interlayer 126 in a three-layer stacking manner.

[0072] like Figure 5 and Figure 6 As shown, the test device further includes a first limiter 140 , which is disposed on the bracket 110 and away from the first test seat 120 along the first direction; the first limiter 140 is used to limit the displacement of the first test piece 122 along the first direction.

[0073] In this embodiment, the test device is further provided with a first limiting member 140, which is arranged at one end away from the first test seat 120. Among them, the first limiting member 140 is arranged on the bracket 110. One end of the first limiting member 140 is connected to the bracket 110, and the other end abuts against the first test piece 122. During the process of the punching device punching the first test piece 122, the force direction of the first test piece 122 is from bottom to top, so that the first test piece 122 will generate an upward displacement. By arranging the first limiting member 140 on the bracket 110, the upward displacement generated by the first test piece 122 is limited, which is beneficial to better punching operation of the first test piece 122, and thus better conduct the roof bolt test in the actual working condition simulation.

[0074] In a specific embodiment, a first limiting member 140 is arranged on the bracket 110 at the uppermost part of the first test piece 122 for limiting, so as to offset the acting force of the support force on the first test piece 122 during the roof bolt support operation, and at the same time avoid the upward displacement of the first limiting member 140 under the action of the punching device.

[0075] Specifically, the first limiting member 140 is made of a hard material with a certain strength, such as steel material or iron material. The first limiting member 140 can be made of ordinary steel material, as long as it can limit the first test piece 122, and at the same time can save the cost of the test device. The first limiting member 140 can be in the form of a limiting strip. Specifically, the steel material or iron material and the size can be selected according to the actual situation.

[0076] As Figure 5 and Figure 6 shown, the second test seat 130 is provided with a second partition 134, and the second partition 134 is arranged in a cross shape; the second test seat 130 is further provided with a support plate 136, and the support plate 136 is arranged on the second partition 134.

[0077] In this embodiment, the second test seat 130 is provided with a second partition 134. Specifically, the second partition 134 is arranged at the bottom of the second test seat 130. Specifically, the second test piece 132 is arranged in the second test seat 130. In order to improve the bearing capacity of the second test seat 130, a cross-shaped partition is arranged at the bottom of the second test seat 130, and a support plate 136 is arranged on the partition, and the second test piece 132 is arranged on the support plate 136.

[0078] Specifically, the support plate 136 can be made of ordinary steel plate, which can provide a stable installation platform for the second test piece 132.

[0079] As Figure 5 and Figure 6As shown, the test device also includes a second limiter 150, which is disposed on the bracket 110 and is disposed away from the punching device along the second direction; the second limiter 150 is used to limit the displacement of the second test piece along the second direction.

[0080] In this embodiment, the test device also includes a second limit member 150, and the second limit member 150 is arranged along the second direction away from the punching device. When the punching device performs a punching operation on the second test piece 132, the force direction of the second test piece 132 is set from right to left, so that the second test piece 132 will be displaced to the left. By setting the second limit member 150 on the bracket 110 on the left side of the second test piece 132, the leftward displacement of the second test piece 132 is limited, which is conducive to better punching the second test piece 132, thereby better simulating the anchor test in actual working conditions.

[0081] In a specific embodiment, specifically, the second piece to be tested 132 is stacked on the support plate 136 in two layers. Specifically, the second piece to be tested 132 is punched from right to left, and the second limiting member 150 is set on the left side of the second piece to be tested 132. One end of the second limiting member 150 is connected to the bracket 110, and the other end is against the second piece to be tested 132. While the second limiting member 150 plays a limiting function, it can also offset the force of the supporting force on the second piece to be tested 132.

[0082] like Figure 1 , Figure 5 As shown, the test device further includes a support base 160 , and the support base 160 is used to support the bracket 110 .

[0083] In this embodiment, the test device also includes a support seat 160. Specifically, the support seat 160 is arranged at the lower part of the bracket 110. The support seat 160 provides support force for the bracket 110, thereby ensuring the stability of the bracket 110. When the first test piece 122 and the second test piece 132 are punched, the real test effect can be simulated.

[0084] like Figure 4 , Figure 6 , Figure 9 As shown, the bracket 110 includes a supporting column 112 and a supporting beam 114 connected to each other; the supporting column 112 and the supporting beam 114 are welded together.

[0085] In this embodiment, the bracket 110 includes a connected support column 112 and a support beam 114, and the support column 112 and the support beam 114 are connected by welding. Specifically, the bracket 110 may include a vertically arranged support column 112 and a horizontally arranged support beam 114, and the support column 112 and the support beam 114 are welded together to ensure the stability of the bracket 110. Among them, Figure 4 It is the layout plan of the experimental device on the plane with an elevation of 6.35m.

[0086] Specifically, the support column 112 and the support beam 114 can be made of hot-rolled H-beams, hot-rolled channel steels, and equal-angle steels.

[0087] In a specific embodiment, when the support column 112 is welded to the support beam 114, full penetration with a groove is required at the splicing joint, and butt welds are used for splicing, and it is ensured that the splicing joint is of equal strength. The distance between the flange splicing joint and the web splicing joint should not be less than 200mm. When the support column 112 and the support beam 114 are rigidly connected, within the range of 500mm above and below the beam flange of the column, the connecting welds between the column flange and the column web or between the wall plates of the box-shaped column should be full penetration groove welds.
