DETAILED DESCRIPTION

[0028] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Embodiment 1 of the present utility model:

[0030] See also Figure 1-Figure 3 and Figure 5 A capacity cylinder for cement concrete volume density test, comprising a cylinder 1 and a protective cover 2, wherein the protective cover 2 is detachably mounted on the upper end of the cylinder 1, and the protective cover 2 is arranged along the circumferential direction of the cylinder 1; the protective cover 2 can prevent the cement concrete from falling outside the cylinder 1 when the cement concrete is loaded into the cylinder 1, so that the cement concrete can be loaded into the cylinder 1 more easily; in addition, when the capacity cylinder filled with cement concrete is placed on a vibration table, the presence of the protective cover 2 can effectively prevent the cement concrete in the cylinder from overflowing from the cylinder during the vibration process, and prevent the periphery of the cylinder 1 from being contaminated. This avoids the need for test personnel to wipe the outer wall of the capacity cylinder with a towel after the vibration ends due to the overflow of cement concrete during the vibration process, thereby reducing the labor intensity of test personnel, reducing the time required for the test, and improving the efficiency of the test.

[0031] Specifically, the protective cover 2 includes an overlap portion 201, a receiving portion 202 and a protective portion 203, wherein the overlap portion 201 overlaps the upper edge of the cylinder 1, the receiving portion 202 is located between the overlap portion 201 and the protective portion 203, and the protective portion 203 is arranged to be inclined upward in a direction away from the cylinder 1. The protective cover 2 can be made of an integral molding, and the material of the protective cover 2 can be stainless steel, iron, hard plastic, etc.

[0032] In order to better fix the protective cover 2 on the cylinder 1 and prevent it from falling off the cylinder 1 during vibration, and to facilitate the disassembly of the protective cover 2, two locking assemblies are fixedly installed on the cylinder 1, and the two locking assemblies are evenly arranged along the circumferential direction of the cylinder 1; the protective cover 2 is provided with a connecting piece that cooperates with the locking assembly.

[0033] Embodiment 2 of the present utility model:

[0034] See also Figure 1-Figure 6 This embodiment is a further improvement on the basis of the first embodiment. The same parts as the first embodiment are not repeated here. Only the improved points are described. The locking assembly includes a connecting block 3 and a limiting rod 4. The connecting block 3 is fixedly mounted on the cylinder 1 by welding. A mounting hole 301 is opened on the connecting block 3. The mounting hole 301 is arranged along the length direction of the cylinder 1. One end of the limit rod 4 passes through the connection block 3 and extends into the mounting hole 301. The limit rod 4 is arranged in a direction perpendicular to the cylinder 1. A compression spring 5 is sleeved on the limit rod 4. One end of the compression spring 5 is fixedly installed on the limit rod 4 by welding, and the other end of the compression spring 5 is fixedly installed on the side of the connection block 3 away from the cylinder 1 by welding. The function of the compression spring 5 is to provide a force for the limit rod 4 to approach the cylinder 1. When there is no external force, one end of the limit rod 4 is always located in the mounting hole 301 under the action of the compression spring 5, and the position remains unchanged. When subjected to an outward pulling force, that is, a force away from the cylinder 1, the compression spring 5 first returns to a natural state as the pulling force increases, and then is stretched, so that the limit rod 4 can move in a direction away from the cylinder 1, thereby facilitating the insertion of the connector into the mounting hole 301. When the external force is removed, the compression spring 5 will be reset to its original position, thereby driving the limit rod 4 to reset. The locking assembly designed in this way can meet the requirements of rapid installation and fixation of the protective cover 2, thereby improving the efficiency of the test.

[0035] The connecting member is a connecting rod 6 , which is fixedly mounted on the bottom of the protective cover 2 by welding or gluing. The connecting rod 6 is matched with the mounting hole 301 , and a limiting hole 601 matched with the limiting rod 4 is formed on the connecting rod 6 .

[0036] Specifically, when installing the protective cover 2, first pull the limiting rod 4 outward and then insert the connecting rod 6 into the corresponding mounting hole 301 on the connecting block 3. When the overlapping portion 201 of the protective cover 2 is overlapped on the upper edge of the cylinder 1, the limiting hole 601 on the connecting rod 6 is exactly opposite to the limiting rod 4. When the limiting rod 4 is released, the limiting rod 4 passes through the limiting hole 601 and resets under the action of the compression spring 5. With the cooperation of the limiting rod 4 and the limiting hole 601, the protective cover 2 can be firmly fixed on the cylinder 1 to prevent it from falling off.

[0037] In order to prevent cement concrete from entering between the overlap portion 201 and the upper edge of the cylinder 1, we adopted a method in which the lower surface of the overlap portion 201 is completely in contact with the upper edge of the cylinder 1 when the protective cover 2 is fixed on the cylinder 1. Here, the upper edge of the cylinder 1 refers to the end face of the open end of the cylinder, and the end face is a plane.

[0038] In order to facilitate pulling the limiting rod 4 , a handle 7 is provided at one end of the limiting rod 4 away from the cylinder 1 .

[0039] Embodiment 3 of the present utility model:

[0040] This embodiment is a further improvement on the basis of the second embodiment, and the same parts are not repeated here, and only the improved points are described.

[0041] See also Figure 7-Figure 9 After the capacity cylinder is vibrated on the vibration table, the surface of the cylinder needs to be smoothed. In order to avoid the influence of the protective cover 2 on the smoothing, a limiting groove 101 is opened along the circumferential direction of the cylinder 1 at the edge of the cylinder mouth of the cylinder 1, and the overlapping part 201 is adapted to the limiting groove 101, and the upper surface of the overlapping part 201 is flush with the upper end of the cylinder 1.

[0042] In order to ensure that the overlapping portion 201 can better cooperate with the limiting groove 101 when the protective cover 2 is installed, the cross section of the limiting groove 101 is designed to be L-shaped.

[0043] In order to facilitate the movement of the protective cover 2, a handle 8 is provided on the protective cover 2. The handles 8 are two and are symmetrically arranged.

[0044] In order to facilitate the movement of the volume cylinder, two handles 9 are fixedly provided on the outer circumference of the cylinder body 1 , and the two handles 9 are symmetrically arranged with respect to the cylinder body 1 .

[0045] In the present application, the locking assembly may also choose to use a spring buckle or other mechanism that can achieve quick installation and disassembly.

[0046] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
