Description

Technical Field

[0001] The utility model particularly relates to a cement mortar vibrating table. Background Art

[0002] The cement mortar vibrating table is mainly used to vibrate the material and reduce the air and gaps in the material. Before the density test of the cement test block, the cement mortar is often vibrated into a cement test block by the cement mortar vibrating table, which is conducive to testing the cement mortar, and then improving the quality of the cement used in construction, which is conducive to achieving the purpose of exquisite construction and green building construction. During the test, the test mold is first placed on the table, and then the mold sleeve is rotated to press the test mold, and then the mold sleeve is fixed with a locking part. The existing locking method is generally to provide a threaded barrel on the table, and a connecting rod on the mold sleeve. The connecting rod cooperates with the thread of the threaded barrel to lock the mold sleeve. During the vibration of the cement sample, the connecting rod and the threaded barrel are also in a vibrating state. The threaded connection is subjected to long-term vibration, resulting in wear and loosening of the contact surface. Then the mold sleeve may be unable to press the test mold, thereby affecting the vibration effect of the cement test block. Utility Model Content

[0028] Further, the clamp 8 is provided with a pull rod 15.

[0029] The working principle of the utility model is:

[0030] In use, the test mold is placed on the table 3, the mold cover 5 is rotated to press one side of the mold cover 5 on the test mold, then the clamp 8 and the mounting seat 7 are connected and locked by the locking member, as an embodiment 1, the locking member can be selected as the bolt 1-1 to be realized, then the driving device 4 (the driving device 4 can be selected as the driving cylinder or the telescopic motor to be realized) is started, the driving device 4 drives the table 3 to move up and down to drive the transmission rod 2, so that the test mold is in a state of shaking, thereby reducing the air and gap in the cement and enhancing the compactness of the cement. Considering the threaded connection between the locking member, the clamp 8 and the mounting seat 7, after multiple vibration experiments, the contact surface of the threaded connection is prone to wear and looseness; therefore, the clamp 8 is provided with a pressing assembly, and the working principle of the pressing assembly will be described in detail below:

[0031] When the threaded connection between the locking piece, the hoop 8 and the mounting seat 7 is in a normal state, the inner cavity formed by the hoop 8 and the mounting seat 7 can hold the connecting rod 6, that is, the pressure block 93 is in a state of being retracted in the mounting groove 91, and the lower end of the pressure block 93 is just abutted against the outer periphery of the connecting rod 6; when the threaded connection strength between the locking piece, the hoop 8 and the mounting seat 7 decreases, the longitudinal sectional area of the inner cavity formed by the hoop 8 and the mounting seat 7 increases, at this time the connecting rod 6 is easy to be displaced in the inner cavity, and at this time the pressure block 93 will extend out of the opening 94 of the hoop 8 under the action of the first elastic member 92, and finally the pressure block 93 is abutted against the connecting rod 6; considering that the connecting rod 6 is continuously in a vibrating state in the cement compaction experiment, the application further provides a swing arm 13 on each side of the pressure block 93, and a fixed rod 14 is arranged in the mounting groove 91 on each side of the fixed plate 10, a linkage block 12 is slidably arranged on each fixed rod 14, and a second elastic member 140 is further sleeved on each fixed rod 14 away from the fixed plate 10; when the pressure block 93 is abutted against the end of the connecting rod 6, the connecting rod 6 first has an upward force on the pressure block 93, and the pressure block 93 is partially moved upward, because the swing arms 13 are connected to the two sides of the pressure block 93 respectively, the swing arms 13 drive the linkage blocks 12 to move on the fixed rods 14, and the linkage blocks 12 press the second elastic members 140; because the force is mutual, the swing arms 13 also have a downward force on the pressure block 93, and the first elastic member 92 also drives the telescopic rod 11 to have a downward force on the pressure block 93, so that the design can increase the pressure of the pressure block 93 on the connecting rod 6, thereby enhancing the pressing effect on the connecting rod 6; that is, even if the threaded connection between the hoop 8 and the mounting seat 7 is loose, the pressure block 93 of the pressing assembly will press the connecting rod 6 under the action of the first elastic member 92 and the second elastic member 140, that is, the problem of loosening of the connecting rod 6 can be prevented, so as to improve the compaction effect of the cement. The first elastic member 92 and the second elastic member 140 mentioned in the above embodiment can be realized by a spring.

[0032] In the above technology, a pull rod 15 is arranged at the upper end of the hoop 8 for the convenience of the operator.

[0033] The application is provided to prevent the connecting rod 6 from loosening, and the pressing assembly is arranged on the hoop 8, so that even if the threaded connection strength between the hoop 8 and the mounting seat 7 decreases, the lower end of the pressing assembly can press the connecting rod 6, effectively avoiding the influence of the loosening of the connecting rod 6 on the compaction effect of the cement.

[0034] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
