Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete slump test device. Background Art
[0002] The slump test mainly refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The slump test uses a quantitative indicator to measure the degree of its degree, which is used to determine whether the construction can proceed normally.
[0003] Traditional concrete slump test methods are mostly performed manually by construction workers. However, when lifting the slump test cylinder, it is not easy to lift it vertically upward, which may affect the slump of concrete and may affect the accuracy of the results.
[0004] Therefore, it is urgent to set up a concrete slump test device that ensures the vertical upward movement of the slump test tube. Utility Model Content
[0005] In order to overcome the disadvantage that it is difficult to lift the slump test tube vertically upward, which may affect the slump of concrete and further affect the accuracy of the result, the utility model provides a concrete slump test device which ensures the vertical upward movement of the slump test tube.
[0006] The technical solution is: a concrete slump test device, including a measuring table, a slump bucket, a motor, a rack and a transmission gear. A motor is installed above one side of the measuring table, and the output shaft of the motor is connected to the transmission gear through a coupling. A first slide groove is opened in one side of the measuring table, and a rack is slidably arranged in the first slide groove, and the rack is meshed with the transmission gear. A slump bucket is placed above the measuring table, and the slump bucket is fixed to the end of the rack away from the tooth marks.
[0007] Furthermore, it also includes a limit rod, a support arm and a sliding block. Four support arms are fixed on the upper side of one side of the measuring table. Two support arms on one side have inherent limit rods. A second sliding groove is opened on the inner side of the limit rod. A sliding block is slidably arranged between the second sliding grooves, and a collapse bucket is fixed in the middle of the sliding block.
[0008] Furthermore, it also includes a concrete recovery bucket, a valve and a discharge port. The discharge port is opened on the measuring table, and a valve is rotatably arranged on the measuring table. The valve covers the discharge port, and a concrete recovery bucket is placed directly below the discharge port.
[0009] Furthermore, a tool box is included, and the tool box is fixed on the measuring table.
[0010] Furthermore, a measuring ruler is included, and the measuring ruler is hung on the limiting rod.
[0011] Beneficial effects of the utility model:
[0012] 1. By starting the motor, the output shaft of the motor drives the transmission gear to rotate, and the transmission gear meshes with the rack, thereby driving the rack to move vertically upward. The vertical upward movement of the rack drives the slump bucket upward, so that the slump bucket is separated from the internal concrete, so that there is no need to manually separate the slump bucket and the vertical upward movement cannot be controlled, resulting in errors in the experiment.
[0013] 2. By setting a vertically downward limit rod, the moving direction of the collapse bucket is limited to ensure that the collapse bucket moves vertically upward, avoiding external interference that causes slight swinging of the collapse bucket when it moves vertically.
[0014] 3. By turning the valve so that it no longer blocks the discharge port, the concrete falls into the concrete recovery bucket through the discharge port, and the concrete after the experiment is collected and processed to facilitate cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is described in detail below in conjunction with the accompanying drawings. Example 1
[0021] A concrete slump test device, such as Figure 1 and Figure 2As shown, it includes a measuring table 1, a tool box 2, a slump bucket 6, a motor 9, a rack 10, a measuring ruler 11 and a transmission gear 13. The tool box 2 is fixed on the measuring table 1. The tool box 2 is used to store tools to avoid being discarded anywhere. The motor 9 is installed on the upper left side of the measuring table 1 by screws. The output shaft of the motor 9 is connected to the transmission gear 13 through a coupling. A first slide groove 1001 is opened in the left side of the measuring table 1. A rack 10 is slidably arranged in the first slide groove 1001. The rack 10 and the transmission gear 13 is engaged, a slump bucket 6 is placed above the measuring table 1, and the slump bucket 6 is welded and fixed to the end of the rack 10 away from the tooth mark, and the transmission gear 13 is driven to rotate by the output shaft of the motor 9. The transmission gear 13 is engaged with the rack 10, thereby driving the rack 10 to move vertically upward. The vertical upward movement of the rack 10 drives the slump bucket 6 to move upward, thereby separating the slump bucket 6 from the internal concrete, and a measuring ruler 11 is hung on the measuring table 1. The measuring ruler 11 measures the collapsed concrete to obtain the slump degree.
[0022] When the device is needed to test the slump of concrete, first pour the evenly mixed concrete into the slump bucket 6, then take out the tools from the tool box 2, and tamp the concrete inside the slump bucket 6 to ensure the accuracy of the experiment. After the slump bucket 6 is filled with concrete, the tools are cleaned and put back into the tool box 2 to avoid being discarded anywhere. The motor 9 is started, and the output shaft of the motor 9 drives the transmission gear 13 to rotate. The transmission gear 13 engages with the rack 10, thereby driving the rack 10 to move vertically upward. The vertical upward movement of the rack 10 drives the slump bucket 6 to move upward, thereby separating the slump bucket 6 from the internal concrete, so that there is no need to manually separate the slump bucket 6 and the vertical upward movement cannot be controlled, resulting in errors in the experiment. Then, the collapsed concrete is measured using a measuring ruler 11 to obtain the slump. Example 2
[0023] On the basis of Example 1, Figure 3 As shown, it also includes a limit rod 7, a support arm 8 and a sliding block 801. Four support arms 8 are fixed on the upper right side of the measuring table 1 by screws. Two support arms 8 on one side are welded with inherent limit rods 7. A second sliding groove 12 is opened on the inner side of the limit rod 7. A sliding block 801 is slidably arranged between the second sliding grooves 12. A collapse bucket 6 is fixed in the middle of the sliding block 801. When the rack 10 moves vertically upward to drive the collapse bucket 6 to move upward, the collapse bucket 6 pushes the sliding block 801 to slide in the second sliding groove 12 in the vertically downward limit rod 7, thereby limiting the movement of the collapse bucket 6.
[0024] In order to avoid external interference and ensure that the collapse bucket 6 moves vertically upward, a limit is imposed when the collapse bucket 6 moves vertically upward. That is, when the rack 10 moves vertically upward to drive the collapse bucket 6 to move upward, the collapse bucket 6 pushes the sliding block 801 to slide in the second slide groove 12 in the vertically downward limiting rod 7, thereby limiting the movement of the collapse bucket 6.
[0025] like Figure 4 As shown, it also includes a concrete recovery bucket 3, a valve 4 and a discharge port 5. The discharge port 5 is opened on the measuring table 1. The valve 4 is rotatably arranged on the measuring table 1. The valve 4 covers the discharge port 5. The concrete recovery bucket 3 is placed directly below the discharge port 5.
[0026] In order to facilitate the cleaning of the concrete after the experiment, the valve 4 is turned so that the valve 4 no longer blocks the discharge port 5, and the concrete falls into the concrete recovery bucket 3 through the discharge port 5, and the concrete after the experiment is collected and processed.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
