Description
Technical Field
[0001] The present application relates to the technical field of concrete compression test molds, and in particular to a concrete compression test mold device. Background Art
[0002] The concrete test mold is a special instrument used to form standard specimens of cement, mortar and concrete. The specimens formed can be used to test the compressive strength, flexural strength and other physical properties of cement, mortar and concrete. The traditional test mold box is a box with an open top.
[0003] In the traditional process of solidifying concrete blocks, concrete is first poured evenly into the test mold box. When the concrete solidifies into concrete blocks, the concrete blocks need to be demolded manually. The staff first opens the test mold downward and shakes out the test mold. There is a certain friction between the concrete block and the inner wall of the test mold box. During the demolding process, the concrete test block is easy to get stuck, which makes demolding inconvenient. Utility Model Content
[0004] In order to solve the problem of inconvenience in demoulding concrete blocks, the present application provides a concrete compression test mold device.
[0005] The present application provides a concrete compression test mold device, which adopts the following technical solution:
[0006] A concrete compression test mold device comprises a test mold box and a machine platform, wherein the test mold boxes are arranged in plurality, the bottom walls of the plurality of test mold boxes are provided with through holes, the plurality of test mold boxes are arranged on a machine platform, the machine platform is provided with a docking port, the docking port and the through hole are in the same axial direction, the outer bottom walls of the plurality of test mold boxes are provided with a push rod, the push rod is slidably inserted into the through hole, and the machine platform is provided with a driving component for driving the push rod to move along the height direction of the test mold box.
[0007] By adopting the above technical solution, when demolding, the driving component is used to drive the push rod to move along the height direction of the test mold box, and the push rod pushes the concrete block to move along the height direction of the test mold box. When the push rod pushes the concrete block to the opening of the test mold box, demolding is completed, and workers do not need to manually demold, which makes demolding convenient.
[0008] Furthermore, a push plate is slidably arranged in the trial mold box along the height direction of the trial mold box, the push plate abuts against the inner wall of the trial mold box, and the push rod passes through the through hole and is fixedly connected to the push plate.
[0009] By adopting the above technical solution, during demoulding, the push rod pushes the push plate to move along the height direction of the test mold box, and the push plate expands the contact area with the concrete block, which to a certain extent prevents the concrete block from being damaged due to the small contact area when overcoming the friction force to push the concrete block. When the concrete solidifies into a concrete block, in order to control the shape of the concrete block, the push plate must abut against the inner wall of the test mold box. During the tamping process of the concrete block, the push plate has a certain protective effect on the inner bottom wall of the test mold box.
[0010] Furthermore, the push rod is threadedly connected to the push plate, the push rod is slidably inserted into the docking port, and one end of the push rod is located inside the machine.
[0011] By adopting the above technical solution, when it is found that the push plate is damaged and has a certain impact on the setting of the concrete block, because the push rod and the push plate are threadedly connected, after the push rod is rotated, the push plate is no longer fixed. At this time, the push plate is replaced, which ensures the quality of concrete block forming and the normal use of the device to a certain extent.
[0012] The clamping assembly fixes the test mold box, a through hole is provided in the test mold box, and the push rod moves through the through hole. During the rising process of the push rod, the push rod drives the push plate to push the concrete block to prevent the synchronous movement of the test mold box.
[0013] Furthermore, a plug plate is fixedly provided on the bottom wall of the trial mold box, a slot for inserting the plug plate is provided on the top wall of the machine platform, and the machine platform is provided with a clamping assembly for preventing the trial mold box and the push plate from synchronously displacing.
[0014] Furthermore, the clamping assembly includes two clamping rods and two clamping plates, the clamping rods are fixedly arranged on the machine platform, the clamping plates are arranged on the clamping rods, and the clamping plates abut against the top wall of the trial mold box.
[0015] By adopting the above technical solution, when demoulding, when the push plate drives the concrete block to move along the direction of the test mold box, due to the friction between the concrete block and the test mold box, in order to prevent the concrete block from driving the test mold box to move synchronously, the clamping block abuts against the top wall of the test mold box to block the displacement of the test mold box, and the plug block and the slot block block the displacement of the test mold box on the machine table, thereby fixing the test mold box. When the test mold box needs to be replaced, the test mold box and the plug plate can be pulled out for replacement.
[0016] Furthermore, a sliding sleeve is slidably provided on the clamping rod, the clamping plate is fixedly provided on the sliding sleeve, and a fixing piece for fixing the sliding sleeve is provided on the sliding sleeve.
[0017] Furthermore, the fixing member is configured as a bolt, the bolt is passed through the side wall of the sliding sleeve, the side wall of the sliding sleeve is provided with a threaded hole, the bolt is threadedly connected to the sliding sleeve through the threaded hole, and a friction portion is provided between the bolt and the clamping rod for preventing the relative sliding of the sliding sleeve and the clamping rod.
[0018] By adopting the above technical solution, during demoulding, the sliding sleeve adjusts the position of the clamping plate up and down to adapt to the test mold boxes of different heights. When the bottom side of the clamping plate abuts against the top wall of the test mold box, the clamping plate is fixed by bolts to prevent the test mold box from being unfixed during the demoulding process, causing the test mold box to move and affect normal demoulding.
[0019] Furthermore, the driving assembly includes a connecting plate and a hydraulic cylinder. The driving assembly is located inside the machine. The side of the connecting plate close to the trial mold box is fixedly connected to one end of the push rod, and the piston rod of the hydraulic cylinder is fixedly connected to the bottom wall of the connecting plate.
[0020] By adopting the above technical solution, during demoulding, the hydraulic cylinder drives the connection plate to move, and the connection plate drives the displacement of multiple push rods, and the demoulding of multiple trial mold boxes is achieved by the synchronous displacement of multiple push rods.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The present application sets a push rod, which pushes the concrete block to move along the height direction of the test mold box. When the push rod pushes the concrete block to the opening of the test mold box, demoulding is completed without the need for workers to manually demould, and demoulding is convenient.
[0023] 2. The present application realizes the detachability of the push plate by setting a threaded opening and a threaded connection with the push rod. When the push plate is damaged, it can be replaced.
[0024] 3. The present application sets a clamping assembly to limit the trial mold box, so as to prevent the demoulding box from being displaced synchronously with the concrete block during demoulding due to the unfixed demoulding box. BRIEF DESCRIPTION OF THE DRAWINGS
