Description
Technical Field
The application relates to the technical field of concrete slump measurement, in particular to a concrete slump measurement device.
Background
The conventional test method for slump of plastic concrete is as follows: filling concrete mixture into a horn-shaped slump barrel with the upper opening diameter of 100mm, the lower opening diameter of 200mm and the height of 300mm for three times, uniformly tamping the concrete mixture from outside to inside along the periphery of the barrel wall by using a tamping rod after each filling, and trowelling the upper opening after tamping. After the slump barrel is pulled up, the slump phenomenon is generated by concrete due to self gravity, and the height difference of the highest point of the concrete mixture after slump is subtracted by the height of the slump barrel (300 mm), which is called slump.
The manual tamping method has a great influence on the slump measurement, because when the concrete is insufficiently tamped, the problems of bubbles, caking, uneven mixing and the like exist in the concrete. For this purpose, a solution is proposed in combination with vibrating mechanical equipment for improving the problems that exist in concrete slump measurement.

The rest of the structure is the same as that of embodiment 1.
Example 3
Referring to fig. 3 to 5, a third embodiment of the present application is different from the second embodiment in that: the driving clamping assembly 301 comprises a limit sliding block 301a, a driving shaft 301b with one end rotatably arranged at the top of the limit sliding block 301a, a driving sleeve 301c sleeved on the driving shaft 301b, and driving rods 301d symmetrically hinged to two sides of the driving sleeve 301 c; the limit sliding block 301a is matched and slides in the limit sliding groove 203b-2; the end of the drive rod 301d remote from the drive sleeve 301c is hinged to the side wall of the sliding clamp plate 302.

The sliding clamp 302 is symmetrically provided with grooves 302a at both ends, which slide on the top side wall of the platen 203b through the grooves 302 a.
The driven clamping assembly 303 comprises a limiting clamping block 303a, a diamond-shaped movable frame 303b connected with the limiting clamping block 303a, and driven rods 303c symmetrically arranged on two sides of the diamond-shaped movable frame 303 b; one end of the diamond-shaped movable frame 303b, which is far away from the limiting clamp block 303a, is connected to the limiting column 203b-4; one end of the follower rod 303c remote from the diamond-shaped movable frame 303b is hinged to the side wall of the slide clamp 302.
The limiting slide block 301a, the sliding clamping plate 302 and the limiting clamping block 303a can slide above the notch of the placing groove 203a to limit the positioning ring 101.
Further, compared to embodiment 2, the driving clamping assembly 301 is also used to limit the positioning ring 101 on the driving force input side of the clamping unit 300, specifically, the limit slider 301a and the limit clamping block 303a slide in the limit sliding groove 203b-2 through the flanges on both sides, and when sliding out from the limit sliding groove 203b-2, the driving clamping assembly can be located above the notch of the placing groove 203a, so as to limit the positioning ring 101 placed in the placing groove 203 a.
One end of the driving shaft 301b is connected to the top of the limit sliding block 301a through a bearing, the driving shaft 301b can push the limit sliding block 301a to move, the driving shaft 301b is connected through threads and penetrates through the connecting seat 203b-3, and when the driving shaft 301b and the connecting seat 203b-3 rotate in a threaded mode, the driving shaft 301b can generate axial displacement. The driving sleeve 301c is screwed on the driving shaft 301b, and since the two sides of the driving sleeve 301c are connected with the sliding clamping plate 302 through the driving rod 301d, when the driving shaft 301b rotates, the driving sleeve 301c can generate axial displacement on the driving shaft 301 b. Deflection of the drive rod 301d drives the two sliding jaws 302 to mirror.
The sliding clamp 302 slides on the plate surface of the platen 203b through the groove 302a at the end, so that the sliding clamp 302 can slide parallel to each other, and the slump barrel 100 can be effectively limited without being separated from the plate surface of the platen 203 b.
The driven clamping assembly 300 is driven by the sliding clamping plate 302, so that the limiting clamping block 303a and the limiting sliding block 301a have opposite movement tracks and the same clamping effect. Specifically, the driven rod 303c and the driving rod 301d are symmetrically disposed on both sides of the sliding clamping plate 302, and when the driving rod 301d deflects, the driven rod 303c also deflects along with the movement of the sliding clamping plate 302, and has a symmetrical deflection action with the driving rod 301 d. Further, one end of the diamond-shaped movable frame 303b is connected to the top of the connection table 203b-1 through a limiting post 203b-4, one end corresponding to the limiting post 203b-4 is connected to the side wall of the sliding clamping block 303a, and two sides of the diamond-shaped movable frame 303b are respectively connected to one end of the driven rod 303c in a rotating manner. It changes its own shape by deflection of the follower 303c, and thus serves to push the limit clamp block 303a to move, keeping the limit clamp block 303a to have a movement locus mirror-symmetrical to the limit slider 301 a.
The rest of the structure is the same as that of embodiment 2.
Referring to fig. 1-5, before slump barrel 100 is placed on top of platen 203b, it is necessary to keep stop slide 301a, slide clamp plate 302 and stop clamp block 303a of clamp unit 300 not above the notch of holding groove 201a, i.e. stop slide 301a and stop clamp block 303a are received in stop slide groove 203b-2, slide clamp plate 302 is far from holding groove 201a, so that slump barrel 100 can be placed in holding groove 201a smoothly. When the slump barrel 100 is placed, the rotating handle 301b-1 is shifted to rotate the driving shaft 301b, and due to the connecting seat 203b-3, the driving shaft 301b pushes the limit slider 301a to slide out of the limit chute 203b-2, the driving sleeve 301c gradually approaches the connecting seat 203b-3, so that the deflection angle of the driving rod 301d becomes smaller, and the two sliding clamping plates 302 are pulled to approach each other. In synchronization, when the sliding clamping plate 302 gradually approaches, the diamond-shaped movable clamp 303b gradually deforms from square to sharp-angled diamond, the limiting clamping block 303a is pushed to slide in the limiting sliding groove 203b-2, and when the limiting sliding block 301a, the sliding clamping plate 302 and the limiting clamping block 303a are all positioned above the notch of the placing groove 201a, the limiting sliding block 301a, the sliding clamping plate 302 and the limiting clamping block 303a can be limited in four directions of the positioning ring 101, so that stable limiting of the slump barrel 100 is ensured. The whole structure is simple to operate, and the clamping and fixing effects are remarkable.
It should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered in the scope of the claims of the present application.
