Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of large plate test block cutting, in particular to a fixed platform used for large plate test block cutting. Background Art
[0002] At present, shotcrete is an important construction method in tunnel support projects and other protective reinforcement projects. When testing the strength of shotcrete, it is necessary to first use the same construction process to make a large plate test block of shotcrete. The size of the large plate test block is 450mm*350mm*120mm. When testing the strength of shotcrete in tunnel projects, the large plate test block must be cut into a standard size of 100mm*100mm*100mm. The allowable deviation of the size of the large plate test block after cutting is ≤±1mm for the side length, and the vertical angle deviation is less than 2 degrees.
[0003] The traditional molding method is not firmly fixed, and the large plate test block is prone to deviation, so that the molded large plate test block does not meet the standard size requirements and cannot be used. In addition, when cutting large plate test blocks of shotcrete large plates, personnel are required to assist in fixing, so as to improve the accuracy of cutting and molding of large plate test blocks and reduce the scrap rate of large plate test blocks. Due to the large size of large plate test blocks, the edges are easily cracked when cutting due to the influence of gravity and vibration during the cutting process, making the molded large plate test blocks prone to chipping and damage.

[0014] In the embodiment of the present application, since the pressing member needs to move up and down to fix the large plate test block, the bolt can move in the threaded hole, and after moving to a suitable distance, it can also fix the top of the large plate test block.
[0015] In combination with the first aspect, in one implementation, the plane where the two first limiting columns are located is perpendicular to the side baffle.
[0016] In the embodiment of the present application, since the cutting surface of the large plate test block needs to be perpendicular to the side baffle, the two side surfaces of the large plate test block are flush with the inner surfaces of the two first limit columns, which is beneficial to ensure that the cutting surface of the large plate test block is flush when cutting the large plate test block.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0035] The embodiment of the present application provides a fixed platform for cutting large plate test blocks, which can solve the problem in the prior art that large plate test blocks are prone to cracking when being cut and separated, making the formed large plate test blocks prone to chipping and damage.
[0036] like Figure 1 As shown, the present application provides an embodiment of a fixed platform for cutting large plate test blocks, the fixed platform comprising: a platform 1 and a first fixing device 2, the platform 1 is used to place the large plate test block, and the first fixing device 2 is used to limit the large plate test block. The bottom of the platform 1 is provided with a support member to support itself, and the support member is used to ensure the stability of the platform 1. The first fixing device 2 is installed on the upper surface of the platform 1, and the first fixing device 2 is a semi-enclosed structure, which includes two oppositely arranged side baffles 21 and a front baffle 30, and the two ends of the front baffle 30 are respectively close to the inner surfaces of the two side baffles 21. For the convenience of description, in this embodiment, the position of the front baffle 30 is defined as the front end, and the other end of the side baffle 21 is defined as the end. A connecting frame 22 is provided across the ends of the two side baffles 21, and a first limiting column 28 is provided on the inner surface of each side baffle 21 near the front baffle 30. When in use, the large plate test block is located in the first fixing device 2, and the first limiting column 28 and the front baffle 30 abut against the side of the large plate test block. The connecting frame 22 is equipped with a lifting and lowering pressing member facing the large plate test block.
[0037] During cutting in the present application, the front end of the large plate test block is abutted against the inner wall of the front baffle 30, and the two sides of the large plate test block near the front end are respectively abutted against the inner sides of the two first limit columns 28, and the pressing parts installed on the adjusting connecting frame 22 are pressed against the part near the end of the large plate test block to prevent the large plate test block from shifting during cutting, thus avoiding the occurrence of many chipping corners and flying stones, and minimizing the influence of gravity and vibration on the cutting and forming accuracy of the large plate test block, thereby improving the qualified rate of the forming of the large plate test block.
[0038] like Figure 1 As shown, in some embodiments, the connecting frame 22 is two first door frames 221 arranged side by side, each first door frame 221 includes a column 2211 installed on the outer surface of the side baffle 21 and a beam 2212 connecting the top ends of the two columns, and the two beams are connected by a plurality of fixing blocks 23, and the fixing blocks 23 are provided with threaded holes 24, and a liftable pressure piece is installed in the threaded hole 24, and the top of the large plate test block is pressed by moving the pressure piece in the threaded hole 24 to prevent the large plate test block from shifting during cutting.
[0039] In other embodiments, the connecting frame 22 is a second door frame (not shown in the figure), which includes a vertical plate installed on the outer surface of the side baffle 21 and a horizontal plate connecting the top ends of the two vertical plates. The horizontal plate is provided with a plurality of threaded holes at intervals, and liftable pressure members are installed in the threaded holes. By moving the pressure members in the threaded holes, the top of the large plate test block is fixed to prevent the large plate test block from shifting during cutting.
[0040] like Figure 1As shown, further, the liftable pressure member is a bolt 25. Since the pressure member needs to move up and down to fix the large plate test block, the bolt 25 can move in the threaded hole and can fix the top of the large plate test block after moving to a suitable distance.
[0041] In some embodiments, the plane where the two first limit columns 28 are located is perpendicular to the side baffle 21. Since the cutting surface of the large plate test block needs to be perpendicular to the side baffle 21, the two side surfaces of the large plate test block are flush with the inner surfaces of the two first limit columns 28, which is beneficial to ensure that the cutting surface of the large plate test block is flush when cutting the large plate test block.
[0042] like Figure 1 As shown, in some embodiments, a second limiting column 29 is provided at the connection between the inner surface of the side baffle 21 and the front baffle 30, and the second limiting column 29 is located on the side of the front baffle 30 away from the first limiting column 28.

In this embodiment, there are two second limiting columns 29, which are respectively located at the contact between the inner surfaces of the two side baffles 21 and the front baffle 30, and are provided on the side surface of the front baffle 30 away from the first limiting column 28.

When cutting the large plate test block, the large plate test block is easily offset due to the influence of the cutting force, and the second fixing device is provided to prevent the large plate test block from offsetting during cutting.
[0044] like Figure 1 As shown, in some embodiments, the fixed platform further includes a reinforcing plate 31 for reinforcing the side baffle 21, and the reinforcing plate 31 is connected to the outer surface of the side baffle 21 and is adjacent to the end of the side baffle 21. When cutting a large plate test block, the side baffle 21 is easily shaken by the cutting force, and the reinforcement plate 31 is provided to reduce the effect of the cutting force on the side baffle 21. In this embodiment, there are two reinforcing plates 31, which are respectively connected to the outer surface of the side baffle 21 and adjacent to the end of the side baffle 21.
[0045] like Figure 1As shown, in some embodiments, a scale ruler 27 for measuring the large plate test block is provided along the length direction on the inner surface of the side baffle plate 21. The large plate test block is placed in the first fixing device 2, and the first limit column 28 and the front baffle plate 30 abut against the side of the large plate test block.

[0046] like Figure 1 As shown, in some embodiments, the support member includes a platform leg 11 and four first connecting members 12, the platform legs 11 are located at the four corners of the platform 1, and two adjacent platform legs 11 are connected by a first connecting member 12. Since the platform 1 is used to place a large plate test block, the platform 1 needs to meet a certain stability. By arranging the platform legs 11 at the four corners of the platform 1 and the first connecting members 12 between two adjacent platform legs 11, it can be ensured that the large plate test block is not easy to fall off the platform 1. In this embodiment, the first connecting member 12 is a connecting rod.
[0047] In other embodiments, the platform 1 and the platform legs 11 are made of solid iron bars or steel bars, thick steel plates and other materials to increase the basic weight of the entire platform to reduce the impact of vibration on cutting accuracy during cutting and prevent the platform from moving at will.
[0048] In the second aspect, the present application provides an embodiment of a fixed platform for cutting a large plate test block. When in use, the large plate test block is placed on the platform 1, and the large plate test block is moved along the length direction of the platform 1, and the two side surfaces of the large plate test block are placed between the two first limit columns 28, and the front end of the large plate test block abuts the front baffle 30, and then the pressing piece on the connecting frame 22 is moved to press the pressing piece against the top surface of the large plate test block, and the large plate test block is cut in a direction perpendicular to the side baffle 21.
[0049] In summary, the present application arranges the first fixing device 2 on the platform 1, and the first fixing device 2 is combined into a semi-enclosed structure through two side baffles 21, a front baffle 30 and a connecting frame 22. Two first limiting columns 28 are provided on the inner surface of the side baffle 21 near the front baffle 30. When cutting, the front end of the large plate test block is abutted against the inner wall of the front baffle 30, and the two sides of the large plate test block near the front end are respectively abutted against the inner sides of the two first limiting columns 28. By adjusting the pressing piece installed on the connecting frame 22, the part near the end of the large plate test block is pressed to prevent the large plate test block from shifting during cutting, avoid the occurrence of many chipping and flying stones, minimize the influence of gravity and vibration on the cutting and forming accuracy of the large plate test block, and improve the qualified rate of the forming of the large plate test block.
