Description

Technical Field

[0001] The present application relates to the technical field of concrete testing, and in particular to a concrete pressure testing device. Background Art

[0002] Concrete is a composite material. In addition to the common sand, stone, water, and cementitious materials, various additives and admixtures are added. Therefore, the properties of concrete are very complex and it is difficult to directly test its properties. The compressive strength test of concrete can be carried out by observing and measuring the deformation of concrete under a certain pressure, thereby obtaining the compressive strength of concrete. It is an important means to ensure the quality and safety of concrete.

[0003] General concrete pressure testing requires testing multiple pieces of concrete. Because the compressive strength of concrete is an important indicator for evaluating concrete quality and is also a basic condition for the safe use of buildings. By testing multiple pieces of concrete, the compressive strength of concrete can be evaluated more accurately, thereby ensuring the quality and safety of concrete.

[0004] After the concrete is pressed, most existing concrete pressure detection devices use manual cleaning to deal with the crushed debris. This method requires operators to manually clean the debris inside the equipment, which is not only labor-intensive and inefficient, but also may pose safety hazards. Utility Model Content

[0005] The purpose of the present application is to solve the problem of low efficiency in handling crushed debris by manual cleaning, and the present application provides a concrete pressure testing device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] The cam is provided with a toothed structure which is adapted to move the drive shaft to a desired position, and a guide wheel is provided at one end of the toothed structure to move the drive shaft to a desired position.

[0008] By adopting the above technical scheme, by setting up the coordinated use of the driving assembly and the guiding assembly, it is convenient to drive the extrusion hammer to cooperate with the support plate to extrude the concrete block for detection, and then after the concrete block is broken, the electric push rod is used to push the two transmission rods to deflect away from each other around the hinge axis, and at the same time push the two support plates to move away from each other and retract into the interior of the storage bin, so that the crushed concrete blocks fall into the interior of the receiving box for collection under the action of gravity, thereby facilitating the automatic collection and discharge of crushed concrete debris, and effectively improving the detection efficiency and safety.

[0009] Furthermore, the driving assembly includes a driven wheel fixedly connected to one end of the driving shaft, one end of the driven wheel is sleeved with a synchronous belt, the top of the bracket is fixedly connected to a driving motor, the output end of the driving motor is fixedly connected to a driving wheel, and one end of the synchronous belt is sleeved on the periphery of the driving wheel.

[0010] By adopting the above technical solution, by setting the driven wheel to cooperate with the synchronous belt and the driving wheel, the starting drive motor can drive the driven wheel to drive the driving shaft to rotate, and drive the driving shaft to form a threaded connection with the screw, thereby facilitating the driving screw to push the extrusion hammer to move up and down.

[0011] Furthermore, the guide assembly includes a guide plate fixedly connected to one end of the extrusion hammer, one end of the bracket is fixedly connected to four guide slide bars, the four guide slide bars are arranged in a rectangular shape, and the four corners of the guide plate are slidably connected to the four guide slide bars respectively.

[0012] By adopting the above technical solution, by setting the guide plate and the guide slide rod for use together, it is convenient to guide and fix the axial direction of the extrusion hammer and the screw when the extrusion hammer is driven to move along the length direction of the screw, thereby effectively improving the practicality of the device.

[0013] Furthermore, a protective cover is provided on a sliding sleeve at one end of the extrusion hammer, and four corners of the protective cover are slidably connected to four guide sliding rods respectively.

[0014] By adopting the above technical solution, by setting up the protective cover and the extrusion hammer for use together, it is convenient to form a wrapping cover for the outer periphery of the concrete block when the extrusion hammer extrude the concrete block, thereby effectively reducing the problem of concrete fragments splashing outward and improving the safety of the device.

[0015] Furthermore, a buffer spring is sleeved on one end of the extrusion hammer, and the buffer spring is installed between the guide plate and the protective cover.

[0016] By adopting the above technical solution and arranging the buffer spring and the protective cover for use together, when the driving extrusion hammer drives the protective cover to form a conflict with the base, the protective cover squeezes the buffer spring upward along the length direction of the screw to produce a contraction deformation, thereby effectively reducing the extrusion strength of the protective cover and improving the practicability of the device.

[0017] Furthermore, a supporting slide groove is provided on the inner side of the storage bin, and a supporting sliding block adapted to the supporting slide groove is fixedly connected to one end of the supporting plate.

[0018] By adopting the above technical solution, the supporting strength and stability of the supporting plate are effectively improved by arranging the supporting sliding groove and the supporting sliding block for use in coordination.

[0019] Furthermore, a cyclone separator is fixedly connected to one end of the base, an exhaust pump is fixedly connected to the top of the cyclone separator, an input end of the exhaust pump is connected to the inner top of the cyclone separator, an exhaust port is provided at one end of the protective cover, and an air guide hose connected to the exhaust port is fixedly connected to one end of the cyclone separator.

[0020] By adopting the above technical scheme, by arranging the coordinated use of the exhaust pump and the cyclone separator, it is convenient to start the exhaust pump to draw the debris generated by the concrete blocks within the covering range of the protective cover together with the air into the interior of the cyclone separator for separation of solid and gas, so that dust and other gases fall into the interior of the cyclone separator for collection, thereby effectively reducing the dust generated by concrete debris and improving the practicability of the device.

[0021] Furthermore, a filter screen is fixedly connected to the interior of the air outlet.

[0022] By adopting the above technical solution, a filter net is provided to facilitate filtering and intercepting large-sized concrete debris introduced into the air guide hose and the inside of the cyclone separator, thereby further improving the practicality of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By setting up the coordinated use of the driving assembly and the guiding assembly, it is convenient to drive the extrusion hammer to cooperate with the support plate to extrude the concrete block for detection. Then, after the concrete block is broken, the electric push rod is used to push the two transmission rods to deflect away from each other around the hinge shaft, and at the same time, the two support plates are pushed to move away from each other and retract into the storage bin, so that the crushed concrete blocks fall into the receiving box under the action of gravity for collection, thereby facilitating the automatic collection and discharge of crushed concrete debris, and effectively improving the detection efficiency and safety.

[0025] 2. By setting up the coordinated use of the exhaust pump and the cyclone separator, it is convenient to start the exhaust pump to draw the debris generated by the concrete blocks within the covering range of the protective cover together with the air into the interior of the cyclone separator for separation of solids and gases, so that dust and other gases fall into the interior of the cyclone separator for collection, thereby effectively reducing the dust generated by concrete debris and improving the practicability of the device.
