Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A concrete press machine, as shown in figure 1, comprises a frame 1, a pressing device 2, an upper jacking device 3 and a cleaning device 4. The pressing device 2 is arranged on the upper part of the frame 1 and comprises a screw rod in threaded connection with the frame 1, a hand wheel is connected to the upper end of the screw rod, and a pressing plate is connected to the lower end of the screw rod. The upper supporting device 3 is installed at the lower part of the frame 1, and includes a lift cylinder 31 and a supporting base 32 connected to the upper side of the lift cylinder 31. The concrete test block is placed on the support platform 32, the hand wheel is turned, the pressing plate is tightly attached to the upper side face of the concrete test block, then the lifting oil cylinder 31 drives the support platform 32 to ascend, the concrete test block is subjected to extrusion force, pressurization is stopped when the concrete test block breaks, and the current pressure is recorded.

As shown in fig. 1 and 2, the cleaning device 4 is disposed at the support table 32 and includes a cleaning strip 41 and a collection box 42. The opposite sides above the supporting platform 32 are fixedly connected with guide strips 33, and the cleaning strips 41 are positioned between the two guide strips 33 and are perpendicular to each other. The two ends of the cleaning strip 41 are fixedly connected with guide blocks 411, and the guide strip 33 is provided with a guide groove 331 for the guide blocks 411 to be clamped in and move along the guide strip 33. The cleaning strip 41 is made of metal material, and a film 412 is glued on the side facing the support platform 32, and the film 412 is made of PVC and has a thickness of 0.5 mm. The film 412 is in close contact with the support base 32, so that the debris on the support base 32 can be scraped off during the sliding of the cleaning bar 41 along the guide bar 33. The film 412 prevents the cleaning strips 41 from wearing the support platform 32, so that the surface of the support platform 32 is not smooth enough, and the detection effect of the concrete test block is ensured.

As shown in fig. 1 and 2, a collection box 42 for containing the crushed stones is connected to one side of the support platform 32, the cleaning strip 41 is firstly arranged on one side of the support platform 32 far away from the collection box 42, the cleaning strip 41 slides towards the collection box 42 after the test is finished, the crushed stones can be scraped into the collection box 42, and the trouble that the crushed stones are scattered on the ground and need to be cleaned is avoided. The guide groove 331 is communicated with a moving-out groove 332 for moving out the guide block 411 at the upper side of one end, far away from the collecting box 42, of the guide groove 331, the cleaning strip 41 is slid to one side, far away from the collecting box 42, of the supporting platform 32, then the cleaning strip 41 is lifted up, the guide block 411 moves out along the moving-out groove 332, the cleaning strip 41 can be taken out, and the aged film 412 can be torn down to be attached to a new film 412 again.

As shown in fig. 2 and 3, the baffle 44 is fixedly connected to one side of the upper end of the collecting box 42, which is away from the supporting platform 32, and is obliquely arranged, so that when the operator applies too much force to cause the sliding speed of the cleaning strip 41 to be fast, the broken stones fall on the baffle 44 when flying out of the supporting platform 32 under the driving of the cleaning strip 41, and then fall into the collecting box 42, and the collecting box 42 cannot fly through the collecting box 42 due to inertia, thereby ensuring the collecting effect.

As shown in fig. 2 and 3, the support platform 32 is provided with a recess 322 for a sidewall of the collection box 42 to engage with, so that the crushed stone can smoothly fall into the collection box 42 without being caught at the tight contact position between the collection box 42 and the support platform 32. An inserting plate 43 is fixedly connected to one side of the upper end of the collecting box 42 facing the supporting platform 32, and a slot 321 for inserting the inserting plate 43 is formed in the bottom wall of the receding groove 322. The inner wall is provided with fixed slot 323 on the slot 321, is provided with fixed column 34 in the fixed slot 323, and fixedly connected with fixed spring 35 between fixed column 34 and the fixed slot 323 diapire. The end of the fixing post 34 away from the fixing spring 35 is hemispherical, and the insertion plate 43 is provided with a fixing hole 431 for the fixing post 34 to be inserted into.

When the inserting plate 43 is not inserted into the inserting slot 321, the fixing post 34 is tightly attached to the lower inner wall of the inserting slot 321 under the action of the fixing spring 35. When the collecting box 42 is installed, the inserting plate 43 is inserted into the inserting slot 321, the fixing post 34 is pressed by the inserting plate 43 and retreats into the fixing slot 323 until the inserting plate 43 is completely inserted into the inserting slot 321, the fixing hole 431 is opposite to the fixing slot 323, and the fixing post 34 is clamped into the fixing hole 431 under the action of the fixing spring 35. Therefore, the inserting plate 43 is limited by the fixing column 34 and is not easy to pull out, a certain force is needed, and the trouble that the collecting box 42 is accidentally separated from the supporting platform 32 due to the impact force caused by falling of the broken stones is avoided. The collection box 42 can be detached by pulling away from the support platform 32, so that the broken stones in the collection box 42 can be poured conveniently, and the detachment and the installation are quick and convenient.

The working process is as follows:

after the concrete test block is tested, the concrete test block is taken down, the cleaning strips 41 are pushed towards the collecting box 42 until the guide block 411 moves to be attached to the inner wall of one end of the guide groove 331, the cleaning strips 41 are located at the boundary of the supporting table 32, broken stones are completely scraped into the collecting box 42, and finally the cleaning strips 41 are reset. When the collection box 42 is filled with crushed stones, it is detached and dumped, and then it is returned.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
