Description

Technical Field

[0001] The present application relates to the technical field of foam lightweight soil compressive strength detection, and specifically to a foam lightweight soil compressive strength detection device. Background Art

[0002] Foam lightweight soil is a new type of lightweight material containing a large number of closed pores, which is formed by mechanically foaming the foaming agent through the foaming system of a bubble machine, evenly mixing the foam with cement slurry, and then passing through the pumping system of the foaming machine for cast-in-place construction or mold forming. It is naturally cured and has been widely used in civil engineering fields such as railways, highways, underground, mountain slopes, and municipal engineering.

[0003] However, since the compressive strength required for foam lightweight soil in different application environments is different, it needs to be subjected to a compressive test after solidification. The compressive strength measuring device in the prior art does not have a fixing device for fixing the foam lightweight soil. During the pressing process of the pressure platform, the foam lightweight soil easily tilts to one side, resulting in poor stability of the foam lightweight soil during the test, increasing the inaccuracy of the detection device. A Chinese patent (Announcement No.: CN 211263019U) discloses a foam lightweight soil compressive strength testing device, which is convenient for fixing the foam lightweight soil sample to be tested to ensure stability during the test.

[0004] However, the above patent is not convenient for adjusting the weight of the pressure platform. When the pressure platform tests the sample, the compressive strength test is performed by its own weight and the impact force when it falls. In the above patent, the pressure platform only tests the sample at different heights, which makes the test results have certain limitations. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a foam lightweight soil compressive strength testing device, which has the advantages of easy adjustment and solves the problem of inconvenient adjustment.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a foam lightweight soil compressive strength testing device, comprising a base and a pressure platform, wherein a bracket is fixed to the top of the base, two hydraulic cylinders are fixed inside the bracket, and a horizontal plate is fixed to the lower ends of the two hydraulic cylinders, an adjustment component for adjusting the weight of the pressure platform is provided at the top of the pressure platform, and a clamping component is provided inside the base;

[0007] The adjustment assembly includes two connecting columns, two slots, a placement tube fixedly installed on the top of the two connecting columns, and a clamping structure fixedly installed inside the two placement tubes. Multiple counterweights are placed inside the placement tube, and the slot is opened at the front end of the placement tube.

[0008] By adopting the above technical solution, the weight of the pressure platform itself can be adjusted so that the pressure platform can perform compression tests of different strengths on foam lightweight soil samples under different weights and different heights of gravity, and the test result data of the compressive strength of the foam lightweight soil samples can be enhanced.

[0009] Furthermore, the two connecting columns are fixed to the top of the pressure platform, and the top of the horizontal plate is provided with two connecting holes, and the connecting columns are fixed inside the connecting holes.

[0010] By adopting the above technical solution, the horizontal plate can be connected to the pressure platform through two connecting columns.

[0011] Furthermore, the clamping structure includes two clamping blocks, two sets of springs, two screws and two T-shaped rods fixedly installed on the top of the clamping blocks. The springs are sleeved on the outside of the T-shaped rods, and the screws are rotatably connected to the top of the clamping blocks through bearings.

[0012] By adopting the above technical solution, the counterweight block can be stably positioned inside the placement tube.

[0013] Furthermore, a circular hole is provided at the top end of the placement cylinder for allowing the screw and the T-shaped rod to move in or out of the interior thereof.

[0014] The above technical solution is adopted to reserve sufficient space for the screw rod and the T-shaped rod to move up and down.

[0015] Furthermore, the clamping assembly includes two clamping blocks, two screw rods, a connecting plate fixedly installed on the opposite sides of the two clamping blocks, an electric telescopic rod fixedly installed on the lower end of the connecting plate, an L-shaped plate fixedly installed on the lower end of the electric telescopic rod and a dual-axis motor fixedly installed on the opposite ends of the two screw rods.

[0016] By adopting the above technical solution, the foam lightweight soil sample to be tested can be fixed, thereby ensuring its stability during the testing process.

[0017] Furthermore, through holes for the L-shaped plate to move in or out are provided at both the front and rear ends of the base.

[0018] The above technical solution facilitates the L-shaped plate to move the connecting plate by driving the electric telescopic rod.

[0019] Furthermore, the threads on the outer surfaces of the two screw rods are turned in opposite directions, and the dual-axis motor is fixed to the bottom of the inner cavity of the base.

[0020] By adopting the above technical solution, the screw rod can be rotated in the base.

[0021] Furthermore, threaded holes for threaded connection of the screw rod thereto are provided on opposite sides of the two L-shaped plates.

[0022] The above technical solution is adopted so that the screw rod can drive the L-shaped plate to move.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The foam lightweight soil compressive strength testing device is provided with an adjustment component, which can adjust the weight of the pressure platform itself so that the pressure platform can perform compression tests of different strengths on foam lightweight soil samples under gravity of different weights and different heights, thereby enhancing the test result data of the compressive strength of the foam lightweight soil samples. In addition, the clamping component is provided to clamp and fix the foam lightweight soil sample to be tested. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] See also Figures 1 to 2 In this embodiment, a foam lightweight soil compressive strength testing device includes a base 1 and a pressure platform 5. A bracket 2 is fixed to the top of the base 1, and two hydraulic cylinders 3 are fixed inside the bracket 2. Two fixing holes are provided at the top of the bracket 2 so that the hydraulic cylinders 3 can be fixed inside the bracket 2. A horizontal plate 4 is fixed to the lower ends of the two hydraulic cylinders 3. An adjustment component for adjusting the weight of the pressure platform 5 is provided at the top, and a clamping component is provided inside the base 1.

[0031] See also Figure 2The adjustment component in this embodiment includes two connecting columns 51, two slots 53, a placement tube 52 fixedly installed on the top of the two connecting columns 51, and a clamping structure fixedly installed inside the two placement tubes 52. A plurality of counterweight blocks 54 are placed inside the placement tube 52, and the slot 53 is opened at the front end of the placement tube 52.

[0032] Among them, two connecting columns 51 are fixed to the top of the pressure platform 5, and two connecting holes are opened at the top of the cross plate 4. The connecting columns 51 are fixed inside the connecting holes, so that the two connecting columns 51 can be fixed in the cross plate 4 so that the pressure platform 5 can be connected to the cross plate 4.

[0033] Moreover, two reserved holes are provided at the top of the bracket 2. When the hydraulic cylinder 3 drives the pressure platform 5 to move upward through the cross plate 4, the placement tube 52 can be moved into or out of the bracket 2 through the reserved holes, so as to reserve sufficient moving space for the placement tube 52.

[0034] See also Figure 2 The clamping structure in this embodiment includes two clamping blocks 55, two sets of springs 58, two screws 57 and two T-shaped rods 56 fixedly installed on the top of the clamping block 55. The spring 58 is sleeved on the outside of the T-shaped rod 56, and the screw 57 is rotatably connected to the top of the clamping block 55 through a bearing.

[0035] At the same time, a circular hole is provided at the top of the placement cylinder 52 for the screw 57 and the T-shaped rod 56 to move in or out of the interior. The screw 57 is threadedly connected to the middle circular hole, and the two T-shaped rods 56 on the same side are slidably connected to the inside of the circular hole so as to drive the clamping block 55 to move up and down in the placement cylinder 52.

[0036] See also Figure 1 and Figure 3 The clamping assembly in this embodiment includes two clamping blocks 61, two screw rods 65, a connecting plate 62 fixedly mounted on the opposite sides of the two clamping blocks 61, an electric telescopic rod 63 fixedly mounted on the lower end of the connecting plate 62, an L-shaped plate 64 fixedly mounted on the lower end of the electric telescopic rod 63, and a dual-axis motor 66 fixedly mounted on the opposite ends of the two screw rods 65.

[0037] Secondly, through holes are provided at both the front and rear ends of the base 1 for allowing the L-shaped plate 64 to move in or out, so that the L-shaped plate 64 is connected to the electric telescopic rod 63.

[0038] In addition, the threads on the outer surfaces of the two screw rods 65 rotate in opposite directions. When the dual-axis motor 66 drives the two screw rods 65 to rotate, the two screw rods 65 rotate in opposite directions. The dual-axis motor 66 is fixed to the bottom of the inner cavity of the base 1.

[0039] Furthermore, threaded holes for the screw rod 65 to be threadedly connected thereto are provided on opposite sides of the two L-shaped plates 64 so that the screw rod 65 can drive the two L-shaped plates 64 to move.

[0040] It should be noted that the electronic components appearing in the text are all commonly known to the public in the prior art, and the electrical components appearing in the text are all connected to the controller and the power supply. The control method of this embodiment is controlled by the controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also well known in the art, so this utility model will no longer explain the control method and circuit connection in detail.

[0041] The working principle of the above embodiment is:

[0042] When in use, when the weight of the pressure platform 5 needs to be adjusted, the screw 57 is rotated to drive the pressing block 55 to move upward, and the pressing block 55 squeezes the spring 58 at the same time, so that the pressing block 55 no longer presses and fixes the counterweight 54 at the top, and the counterweight 54 can be added or removed from the placement tube 52. When the weight placed in the two placement tubes 52 reaches the required weight, the screw 57 is rotated to drive the pressing block 55 to move downward, and the pressing block 55 can press and fix the counterweight 54 at the top, thereby ensuring that the counterweight 54 placed in the placement tube 52 can be firmly located therein, and the weight of the pressure platform 5 can be adjusted, so that the pressure platform 5 can perform compression tests of different strengths on foam lightweight soil samples under different weights and different heights of gravity, and the data of the test results can be enhanced;

[0043] After the weight of the pressure platform 5 is adjusted, the sample is placed on the top of the base 1, so that the output end of the dual-axis motor 66 drives the two screw rods 65 to rotate, so that the two screw rods 65 drive the two L-shaped plates 64 to move relative to each other, and the L-shaped plates 64 can drive the two connecting plates 62 to move relative to each other through the electric telescopic rod 63, so that the two connecting plates 62 can drive the two clamping blocks 61 to move relative to each other at the top of the base 1, thereby fixing the sample; and the clamping block 61 can adjust its position height through the electric telescopic rod 63.
