Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a concrete impact resistance testing device. Background Technology

[0002] Concrete is an engineering composite material that binds aggregates together with cementing materials. Generally, when we talk about concrete, we mean cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material with aggregates such as sand and stone, and water (and possibly admixtures and additives) in a certain proportion. This material is widely used in construction, roads, bridges, and other engineering projects due to its high strength and durability.

[0003] Concrete is commonly used in building structures and is required to have a certain level of impact resistance. Therefore, concrete needs to undergo impact resistance testing before use. Although existing testing devices can perform impact resistance tests on concrete, they still have some problems. First, the current testing devices cannot fix the concrete, which leads to the risk of instability during the test. Second, the current testing devices cannot control the magnitude of the impact force by height. Therefore, a concrete impact resistance testing device is needed to solve the above problems.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figure 1 This utility model provides a concrete impact resistance testing device, which includes:

[0017] The test chamber 1 and support legs 2 are fixedly installed at the lower end of the test chamber 1. Support plates 3 are fixedly installed on the inner walls of both sides of the test chamber 1. A fixing mechanism 4 is installed on the support plates 3 and rotatably connected to the test chamber 1. Concrete can be placed on the fixing mechanism 4, which is used to press and fix the concrete. There are two side plates 5, one end of which is fixedly connected to the test chamber 1. The side plates 5 have a sliding groove. The other end of the side plates 5 is fixedly connected to the top plate 7. An impact mechanism 6 is installed on the side plates 5, which is used to impact the concrete on the fixing mechanism 4.

[0018] When using this concrete impact testing device, first place the concrete to be tested on the lower support plate 3, then rotate the control end of the fixing mechanism 4, which will press the concrete on the support plate 3 tightly. Then adjust the power output end of the impact mechanism 6 to a suitable height and turn on the impact mechanism 6. The power output end of the impact mechanism 6 will move downward under the action of gravity, and the impact mechanism 6 will impact the concrete. If the concrete can withstand the impact, the concrete meets the standard; otherwise, the concrete does not meet the standard.

[0019] like Figure 1As shown in the preferred embodiment of this utility model, the fixing mechanism 4 includes: a rotating rod 41, both ends of which are rotatably connected to the inner wall of the test chamber 1, a rotating handle 42 fixedly connected to the rotating rod 41, and a first bevel gear 43 fixedly mounted on the rotating rod 41; a threaded column 44, both ends of which are rotatably connected to the support plate 3, a rotating column 45 fixedly connected to the threaded column 44, and a second bevel gear 46 fixedly mounted on the rotating column 45 and connected to the first bevel gear 43; a guide column 47, both ends of which are fixedly connected to the inner wall of the support plate 3, a lifting plate 48 threadedly connected to the threaded column 44 and mounted on the guide column 47, a pressure plate 49 fixedly mounted on the lifting plate 48, and the lower support plate 3 used to cooperate with the pressure plate 49 to press the concrete.

[0020] When fixing the concrete, turn the handle 42, which drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the first bevel gear 43 to rotate. The first bevel gear 43 drives the second bevel gear 46, the rotating column 45, and the threaded column 44 to rotate. The rotation of the threaded column 44 causes the lifting plate 48 to drive the pressure plate 49 to move downward along the guide column 47. The downward movement of the pressure plate 49 can press the concrete on the lower support plate 3 to ensure the stability of the concrete when it is subjected to impact.

[0021] like Figure 1 and Figure 2 As shown, in a preferred embodiment of this utility model, the impact mechanism 6 includes: a power component 61, which is fixedly installed on one side plate 5, and the output shaft of the power component 61 is fixedly connected to a first gear 62; a shaft 63, whose two ends are rotatably connected to the two side plates 5, a second gear 64 that meshes with the first gear 62 is fixedly provided on one side of the shaft 63, a winding drum 65 is fixedly provided on the shaft 63, a chuck 66 is fixedly provided on one side of the winding drum 65, and the chuck 66 has a locking hole; a clamping assembly 67, which is installed on the other side plate 5, the shaft 63 passes through the clamping assembly 67, and the power output end of the clamping assembly 67 can be locked into the locking hole to restrict the rotation of the chuck 66 and the winding drum 65; a wire rope 68, one end of which is fixedly connected to the winding drum 65, the winding drum 65 can wind or release the wire rope 68, and the wire rope 68 is fixedly connected to a downward punch assembly 69 that is slidably provided in the sliding groove opened in the side plate 5.

[0022] Before conducting the impact test, power component 61, specifically a motor, is activated. The output shaft of power component 61 drives the first gear 62 to rotate, which in turn drives the second gear 64 and shaft 63 to rotate. Shaft 63 drives the winding drum 65 and chuck 66 to rotate. The rotation of winding drum 65 winds up the wire rope 68, thereby pulling the lower impact assembly 69 upward. After adjusting the lower impact assembly 69 to a suitable height, clamping assembly 67 is activated. Clamping assembly 67 can then engage with the clamping hole in chuck 66. At this point, power component 61 can be deactivated. During the test, clamping assembly 67 is activated in reverse. After clamping assembly 67 disengages from the clamping hole in chuck 66, the lower impact assembly 69 accelerates downward under the force of gravity, thus impacting the concrete. If the concrete can withstand the impact, it meets the standard; otherwise, it does not.

[0023] like Figure 1 and Figure 2 As shown, in a preferred embodiment of this utility model, the clamping assembly 67 includes: an electric push rod 671, which is fixedly installed on the inner wall of the other side plate 5, and a sleeve plate 672 is fixedly connected to the power output end of the electric push rod 671, and the sleeve plate 672 is sleeved on the shaft 63; a guide rod 673, which is fixedly connected to the other side plate 5, and a guide sleeve 674 fixedly connected to the sleeve plate 672 is sleeved on the guide rod 673; and a clamping rod 675, which is fixedly connected to the sleeve plate 672, and the clamping rod 675 can be clamped into the clamping hole opened in the chuck 66 to restrict the rotation of the winding drum 65.

[0024] When restricting the rotation of the take-up drum 65, the electric push rod 671 is activated. The electric push rod 671 drives the sleeve plate 672 and the guide sleeve 674 to slide along the guide rod 673. The sleeve plate 672 can then drive the clamping rod 675 into the clamping hole, thereby restricting the rotation of the take-up drum 65 and the chuck 66.

[0025] like Figure 1 As shown, in a preferred embodiment of the present invention, the downward punch assembly 69 includes: a weight 691, which is fixedly connected to a steel wire rope 68, a wheel rod 692 fixedly installed on the weight 691, and a pulley 693 slidably disposed in a groove opened in the side plate 5 installed on the wheel rod 692.

[0026] During the impact test, after the clamping component 67 disengages from the chuck hole opened by the chuck 66, the weight 691 can drive the wheel rod 692 and the pulley 693 to move steadily downward along the slide under the action of gravity. The weight 691 accelerates downward to impact the concrete, thereby completing the impact resistance test of the concrete.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
