DETAILED DESCRIPTION
[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0058] Embodiment 1
[0059] The main purpose of the coarse-grained soil surface vibration test is to determine the maximum dry density of the coarse-grained soil in order to optimize the design and construction in engineering applications.
[0060] The test method is the vibration table method, that is, the test is carried out using a surface vibration compactor. Specifically, the soil sample is vibrated by a coarse-grained soil surface vibration compactor to make the soil sample reach the maximum density state, thereby determining the maximum dry density.
[0061] However, the coarse-grained soil surface vibration compactor in the prior art can only perform a maximum dry density test on the coarse-grained soil, and its function is relatively single.
[0062] For example: The main purpose of the concrete compaction table is to effectively expel the bubbles inside the precast concrete components through high-frequency vibration and fill them to increase the density of the concrete, making the precast concrete components more compact and durable.
[0063] This compaction process can increase the density of concrete, significantly improve the strength and durability of concrete, and compact the concrete blocks into shape.
[0064] In the prior art, the maximum dry density test of coarse-grained soil and the vibration compaction test of concrete specimens are often performed separately, with one test being performed first and the other being performed later.
[0065] Therefore, the coarse-grained soil surface vibration compactor in the prior art cannot be effectively combined with the concrete vibration compaction table so that the above two tests can be carried out simultaneously.
[0066] More specifically, since the coarse-grained soil surface vibration compactor in the prior art and the concrete vibration compactor have different working principles, the coarse-grained soil surface vibration compactor in the prior art cannot enable the test personnel to conduct the maximum dry density test on the coarse-grained soil while effectively discharging the bubbles inside the precast concrete components and filling them to improve the density of the concrete and vibrate the concrete test blocks into shape.
[0067] Based on this, in order to solve the above technical problems, the coarse-grained soil surface vibration compactor is effectively combined with the concrete vibration table, so that when the test personnel conduct the maximum dry density test on the coarse-grained soil, the bubbles inside the prefabricated concrete components can be effectively discharged and filled at the same time to improve the density of the concrete, so as to vibrate and compact the concrete test block. The following technical solutions are now adopted, as follows:
[0068] like Figure 1-2 As shown, the utility model provides a technical solution:
[0069] A coarse-grained soil surface vibration instrument, comprising:
[0070] Material vibration mechanism 10;
[0071] An annular clamping mechanism 20, the annular clamping mechanism 20 is mounted on the material vibrating mechanism 10;
[0072] A concrete test cylinder 30, which is installed in the annular clamping mechanism 20 and can be clamped and fixed by the annular clamping mechanism 20 after installation;
[0073] Wherein, the inner diameter of the annular clamping mechanism 20 is larger than the outer diameter of the concrete test cylinder 30;
[0074] The concrete test cylinder 30 is used to fill the concrete raw materials to be compacted;
[0075] A coarse-grained soil test cylinder 40, which is detachably mounted on the concrete test cylinder 30;
[0076] The coarse-grained soil test cylinder 40 is used to fill the coarse-grained soil raw material to be compacted;
[0077] A gantry 50, which is mounted on the material vibrating mechanism 10;
[0078] A traction mechanism 70, the traction mechanism 70 having a fixed portion, a traction end and a suspension end, the fixed portion of the traction mechanism 70 is arranged on one side of the material vibration mechanism 10, the suspension end of the traction mechanism 70 is installed on the gantry 50, and the traction end of the traction mechanism 70 passes downward from the suspension end; and
[0079] A tamping hammer 80, the tamping hammer 80 is connected to the traction end of the traction mechanism 70;
[0080] The fixed part of the traction mechanism 70 can retract or release the traction end. When the fixed part of the traction mechanism 70 releases the traction end, the traction end of the traction mechanism 70 can cooperate with the suspension end and make the tamping hammer 80 move downward. During the continuous downward movement of the tamping hammer 80, the tamping hammer 80 can fall into the coarse-grained soil test cylinder 40 and press the coarse-grained soil in the coarse-grained soil test cylinder 40. At this time, the material vibration mechanism 10 is operated. The material vibration mechanism 10 can continuously vibrate when working. When the material vibration mechanism 10 vibrates, the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the tamping hammer 80 can be vibrated synchronously. and the tamping hammer 80 vibrate synchronously. Therefore, under the action of vibration, the concrete raw materials in the concrete test cylinder 30 can discharge the bubbles inside it to the outside and fill it, thereby improving the density of the concrete, thereby compacting the concrete block. The coarse-grained soil raw materials in the coarse-grained soil test cylinder 40 are pressed by the tamping hammer 80. Under the vibration action of the coarse-grained soil test cylinder 40 and the tamping hammer 80, the coarse-grained soil sample in the coarse-grained soil test cylinder 40 can be vibrated, and the tamping hammer 80 can continuously press the soil sample under the action of vibration, so that the soil sample reaches the maximum dense state under the dual action of vibration and compaction, thereby facilitating the test personnel to determine the maximum dry density of the soil sample, and then complete the relative density test of the soil sample.
[0081] The coarse-grained soil surface vibrator realizes the functional integration of different equipment and has the characteristics of dual use in one machine. It can not only complete the relative density test of soil samples, but also be used for the compaction of concrete test blocks.
[0082] Since the concrete test cylinder 30 and the coarse-grained soil test cylinder 40 are installed in an upper and lower state, they are divided into two upper and lower barrels, and the installation and loading and unloading between the concrete test cylinder 30 and the coarse-grained soil test cylinder 40 are convenient. During the test, the relative density test of the soil sample and the vibration compaction test of the concrete test block can be carried out at the same time, thereby reducing the test time and improving the test efficiency.
[0083] Furthermore, during the test, the annular clamping mechanism 20 can effectively clamp and fix the concrete test cylinder 30 . Meanwhile, the annular clamping mechanism 20 can also adapt to concrete test cylinders 30 of various sizes.
[0084] Embodiment 2

[0087] Two groups of vibration components are symmetrically mounted on the workbench 103 .
[0088] In this embodiment, when the two groups of vibration components are working, they can make the workbench 103 vibrate synchronously. Since multiple groups of elastic components are installed between the workbench 103 and the base frame 101, the vibration of the workbench 103 can be intensified under the action of the elastic force of the multiple groups of elastic components, thereby improving the test effects of the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the gantry 50.
[0089] Further, the multiple sets of elastic components each include a lower sleeve 102 fixedly mounted on the four corners of the top of the base frame 101, an upper sleeve 104 fixedly mounted on the four corners of the bottom of the workbench 103, and springs 105 arranged at the four corners between the base frame 101 and the workbench 103;

[0093] In this embodiment, the above is a specific preferred structure of the vibration component, which can make the worktable 103 vibrate synchronously when the two vibration motors 107 work synchronously.
[0094] Embodiment 3
[0095] like Figure 1 as well as Figure 3 As shown, based on the second embodiment, the following improvements are made:
[0096] Further, the annular clamping mechanism 20 includes a fixing ring 201, and the fixing ring 201 is fixedly mounted at the top center of the workbench 103;
[0097] A plurality of nuts 202 are fixedly mounted on the side wall of the fixing ring 201. The plurality of nuts 202 are circumferentially distributed on the side wall of the fixing ring 201, and the inner cavity of each nut 202 is connected to the inner cavity of the fixing ring 201.
[0098] A clamping bolt 203 is threadedly installed in each nut 202 .
[0099] In this embodiment, the above is a specific preferred structure of the annular clamping mechanism 20. Each clamping bolt 203 can be tightened or loosened on the corresponding nut 202. When tightened, the concrete test cylinder 30 installed in the fixing ring 201 can be clamped and fixed. When loosened, the concrete test cylinder 30 can be easily disassembled.
[0100] Furthermore, the nut of each clamping bolt 203 is provided with anti-slip teeth, so that the test personnel can easily rotate it.
[0101] Embodiment 4
[0102] like Figure 1 as well as Figure 4 As shown, based on the third embodiment, the following improvements are made:
[0103] Furthermore, the concrete test cylinder 30 can be inserted and installed in the fixing ring 201 , and after insertion, the bottom of the fixing ring 201 abuts against the top of the workbench 103 .
[0104] When each clamping bolt 203 is tightened inwardly, the end of the screw of each clamping bolt 203 can abut against the lower part of the side wall of the concrete test cylinder 30 and generate a clamping force;
[0105] An inner slot 301 is provided at the upper part of the inner cavity of the concrete test cylinder 30, and the coarse-grained soil test cylinder 40 can be inserted and installed in the inner slot 301;
[0106] The size of the coarse-grained soil test cylinder 40 is smaller than that of the concrete test cylinder 30 , and the outer diameter of the coarse-grained soil test cylinder 40 matches the inner diameter of the inner groove 301 .
[0107] In this embodiment, after the concrete test cylinder 30 is installed in the fixing ring 201, it can be clamped and fixed by multiple clamping bolts 203. In addition, since the coarse-grained soil test cylinder 40 can be plugged and installed in the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the concrete test cylinder 30 can be easily installed and disassembled.
[0108] Embodiment 5
[0109] like Figure 1 As shown, based on the second embodiment, the following improvements are made:
[0110] Furthermore, C-shaped clamps 108 are fixedly mounted on the middle portions of the two opposite sides of the base frame 101;
[0111] A clamping block 501 is integrally formed at the middle of the inner side wall of the two side legs of the gantry 50;
[0112] When the gantry 50 and the material vibrating mechanism 10 are installed, the two clamping blocks 501 can be inserted and installed into the corresponding C-shaped clamping heads 108 .
[0113] In this embodiment, the gantry 50 can be locked and fixed with the material vibration mechanism 10 through the plug-in cooperation of the clamping block 501 and the corresponding C-type clamping head 108, so that the gantry 50 will not deviate outward due to vibration when the coarse-grained soil surface vibrator is in use. Since the gantry 50 and the material vibration mechanism 10 can be locked and fixed through the plug-in cooperation of the clamping block 501 and the C-type clamping head 108, the positions of the gantry 50 and the material vibration mechanism 10 can be kept fixed without deviation, making the whole more stable, and the gantry 50 can also be easily disassembled from the material vibration mechanism 10.
[0114] Embodiment 6
[0115] like Figure 1 , Figure 2 as well as Figure 5 As shown, based on the first embodiment, the following improvements are made:
[0116] Furthermore, the two side legs of the gantry 50 are fixedly mounted with a bottom plate 60 at the corresponding traction mechanism 70;
[0117] The fixed part of the traction mechanism 70 is a winch 701, the traction end of the traction mechanism 70 is a steel wire rope 702, and the suspension end of the traction mechanism 70 includes a wheel frame 703 and a rope wheel 704;
[0118] Wherein, the hoist 701 is fixedly installed on the top of the bottom plate 60;
[0119] The wheel frame 703 is fixedly mounted at the center of the top of the inner wall of the gantry 50, and the rope wheel 704 is rotatably mounted on the wheel frame 703;
[0120] One end of the wire rope 702 is wound on the winding shaft of the winch 701, and the other end passes downward through the wheel groove of the rope wheel 704;
[0121] The wire rope 702 is connected to the tamping hammer 80 at one end away from the winch 701 .
[0122] In this embodiment, the above is a specific preferred structure of the traction mechanism 70. The winch 701 can retract or release the wire rope 702 through its reel. During the process of retracting or releasing the wire rope 702, the wire rope 702 can cooperate with the rope wheel 704 to make the tamping hammer 80 move upward or downward. When the tamping hammer 80 moves upward, the traction mechanism 70 can retract the tamping hammer 80 to the top of the gantry 50. When the tamping hammer 80 moves downward, it can fall into the coarse-grained soil test cylinder 40 to compact the coarse-grained soil sample in the coarse-grained soil test cylinder 40.
[0123] Furthermore, a steel rope lock buckle 801 is fixedly installed at the center of the top circle of the tamping hammer 80 , and the steel rope lock buckle 801 is locked and fixed to the steel wire rope 702 at one end away from the winch 701 .
[0124] In this embodiment, the wire rope 702 is fixed to the wire rope lock 801 at the end away from the winch 701, so that the connection between the two can be more secure.
[0125] Among them, the tamping hammer 80 is cylindrical, the outer diameter of the tamping hammer 80 matches the inner diameter of the coarse-grained soil test cylinder 40, and the position of the tamping hammer 80 corresponds to the position of the coarse-grained soil test cylinder 40, and the central axis of the tamping hammer 80 coincides with the central axis of the coarse-grained soil test cylinder 40.
[0126] In this embodiment, the shape of the tamping hammer 80 can match the inner cavity of the coarse-grained soil test cylinder 40 , so the tamping hammer 80 can fall into the inner cavity of the coarse-grained soil test cylinder 40 during the downward movement.
[0127] In summary, the workflow of the utility model is:
[0128] like Figure 1-5 As shown, the fixed part of the traction mechanism 70 can retract or release the traction end. When the fixed part of the traction mechanism 70 releases the traction end, the traction end of the traction mechanism 70 can cooperate with the suspension end and make the tamping hammer 80 move downward. During the continuous downward movement of the tamping hammer 80, the tamping hammer 80 can fall into the coarse-grained soil test cylinder 40 and press the coarse-grained soil in the coarse-grained soil test cylinder 40. At this time, the material vibration mechanism 10 is operated. The material vibration mechanism 10 can continuously vibrate when working. When the material vibration mechanism 10 vibrates, the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the tamping hammer 80 can be vibrated synchronously. And the tamping hammer 80 vibrates synchronously, therefore, under the action of vibration, the bubbles inside the concrete raw material in the concrete test cylinder 30 can be discharged outward and filled, thereby improving the density of the concrete, so that the concrete test block is vibrated and compacted, and the coarse-grained soil raw material in the coarse-grained soil test cylinder 40 is pressed by the tamping hammer 80, and under the vibration action of the coarse-grained soil test cylinder 40 and the tamping hammer 80, the coarse-grained soil sample in the coarse-grained soil test cylinder 40 can be vibrated, and the tamping hammer 80 can continuously press the soil sample under the action of vibration, so that the soil sample reaches the maximum dense state under the dual action of vibration and compaction, thereby facilitating the test personnel to determine the maximum dry density of the soil sample, and then complete the relative density test of the soil sample.
[0129] The coarse-grained soil surface vibrator realizes the functional integration of different equipment and has the characteristics of dual use in one machine. It can not only complete the relative density test of soil samples, but also be used for the compaction of concrete test blocks.
[0130] Since the concrete test cylinder 30 and the coarse-grained soil test cylinder 40 are installed in an upper and lower state, they are divided into two upper and lower barrels, and the installation and loading and unloading between the concrete test cylinder 30 and the coarse-grained soil test cylinder 40 are convenient. During the test, the relative density test of the soil sample and the vibration compaction test of the concrete test block can be carried out at the same time, thereby reducing the test time and improving the test efficiency.
[0131] Furthermore, during the test, the annular clamping mechanism 20 can effectively clamp and fix the concrete test cylinder 30 . Meanwhile, the annular clamping mechanism 20 can also adapt to concrete test cylinders 30 of various sizes.
[0132] Specifically, when the two sets of vibration components are working, the workbench 103 can be vibrated synchronously. Since multiple sets of elastic components are installed between the workbench 103 and the base frame 101, the vibration of the workbench 103 can be intensified under the elastic force of the multiple sets of elastic components, thereby improving the test effect of the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the gantry 50.
[0133] When the two vibration motors 107 work synchronously, the worktable 103 can be vibrated synchronously;
[0134] Each clamping bolt 203 can be tightened or loosened on the corresponding nut 202. When tightened, the concrete test cylinder 30 installed in the fixing ring 201 can be clamped and fixed. When loosened, the concrete test cylinder 30 can be easily disassembled.
[0135] Each clamping bolt 203 has a nut with anti-slip teeth, so it is convenient for the tester to rotate it;
[0136] When the concrete test cylinder 30 is installed in the fixing ring 201, it can be clamped and fixed by a plurality of clamping bolts 203. In addition, since the coarse-grained soil test cylinder 40 can be plugged and installed in the concrete test cylinder 30, the coarse-grained soil test cylinder 40 and the concrete test cylinder 30 can be conveniently installed and disassembled.
[0137] The gantry 50 can be locked and fixed with the material vibration mechanism 10 by plugging and matching the clamping block 501 with the corresponding C-type clamping head 108, so that when the coarse-grained soil surface vibrator is in use, the gantry 50 will not deviate outward due to vibration. Since the gantry 50 and the material vibration mechanism 10 can be locked and fixed by plugging and matching the clamping block 501 with the C-type clamping head 108, the positions of the gantry 50 and the material vibration mechanism 10 can be kept fixed without deviation, making the whole more stable, and the gantry 50 can also be easily disassembled from the material vibration mechanism 10;
[0138] The hoist 701 can retract or release the wire rope 702 through its reel. During the process of retracting or releasing the wire rope 702, the wire rope 702 can cooperate with the rope wheel 704 to make the tamping hammer 80 move upward or downward. When the tamping hammer 80 moves upward, the traction mechanism 70 can retract the tamping hammer 80 to the top of the gantry 50. When the tamping hammer 80 moves downward, it can fall into the coarse-grained soil test cylinder 40 to compact the coarse-grained soil sample in the coarse-grained soil test cylinder 40.
[0139] The wire rope 702 is fixed to the wire rope lock 801 at one end away from the winch 701, so that the connection between the two can be more secure;
[0140] The tamping hammer 80 is cylindrical, and the outer diameter of the tamping hammer 80 matches the inner diameter of the coarse-grained soil test cylinder 40. Moreover, the position of the tamping hammer 80 corresponds to the position of the coarse-grained soil test cylinder 40, and the central axis of the tamping hammer 80 coincides with the central axis of the coarse-grained soil test cylinder 40.
[0141] The shape of the tamping hammer 80 can match the inner cavity of the coarse-grained soil test cylinder 40 , so the tamping hammer 80 can fall into the inner cavity of the coarse-grained soil test cylinder 40 during the downward movement.
[0142] The above different embodiments can be combined, replaced and used in conjunction with each other.
