Description

Concrete sampler

Technical Field

The utility model relates to a sampler technical field especially relates to a concrete sampler.

Background

As one of the most important civil engineering materials of this generation, the concrete generally needs to pass through processes such as production, transportation, pouring, vibration, maintenance, in order to guarantee construction quality, ensures engineering safety, needs to carry out sample detection to the concrete, and current concrete sampling technique is to put into jar with the container that can sink into the concrete jar, then salvages the container through the rope connection, because the container can't sink into the concrete lower floor, consequently can't take a sample to the concrete lower floor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a concrete sampler.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a concrete sampler, includes the storage pipe, the spiro union has the spiral cover on the one end outer wall of storage pipe, and the central point of spiral cover puts the department and has seted up the through-hole, and sliding connection has the pull rod on the inner wall of through-hole, be fixed with the piston piece on the pull rod, it has the clamping piece that the equidistance distributes to articulate on the storage pipe other end outer wall, the retainer plate has been cup jointed to the bottom of pull rod, it has the link mechanism that the equidistance distributes to articulate on the outer wall of retainer plate, link mechanism includes the bracing piece, and the one end that the retainer plate was kept away from to the bracing piece articulates there are head rod and second connecting rod, head rod and second connecting rod.

Preferably, the middle part of the pull rod is connected with two fastening nuts positioned on the outer side of the piston sheet through external threads.

Preferably, the number of the clamping pieces is 3-4, and the 3-4 clamping pieces form a conical structure.

Preferably, the support rod, the first connecting rod and the second connecting rod form a Y-shaped structure.

Preferably, sealing strips are bonded at the joints of the clamping pieces and the storage tube and the joints of the two adjacent clamping pieces.

The utility model has the advantages that:

insert the concrete lower floor with the storage pipe, promote the pull rod downwards, can make the bracing piece promote head rod and second connecting rod to make the clamping piece rotate to the storage outside of tubes, the clamping piece opens, can stimulate the piston piece through the pull rod and can extract the concrete thick liquid, and can make bracing piece pulling head rod and second connecting rod, thereby make the clamping piece rotate to the storage intraductal side, the clamping piece folds, and it is inboard to include the clamping piece with the stone in the concrete.

Drawings

Fig. 1 is a schematic structural diagram of a concrete sampler provided by the present invention;

fig. 2 is the utility model provides a clamping piece structural schematic of concrete sampler.

In the figure: the device comprises a storage tube 1, a spiral cover 2, a through hole 3, a pull rod 4, a blocking piece 5, a piston piece 6, an external thread 7, a fastening nut 8, a clamping piece 9, a fixing ring 10, a support rod 11, a first connecting rod 12 and a second connecting rod 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a concrete sampler comprises a storage tube 1, a screw cap 2 is screwed on the outer wall of one end of the storage tube 1, a through hole 3 is arranged at the central position of the screw cap 2, a pull rod 4 is connected on the inner wall of the through hole 3 in a sliding manner, a piston sheet 6 is fixed on the pull rod 4, two fastening nuts 8 positioned on the outer side of the piston sheet 6 are connected at the middle part of the pull rod 4 through external threads 7, clamping sheets 9 are hinged on the outer wall of the other end of the storage tube 1 and distributed equidistantly, the number of the clamping sheets 9 is 3-4, the 3-4 clamping sheets 9 form a conical structure, a fixing ring 10 is sleeved at the bottom of the pull rod 4, a connecting rod mechanism is hinged on the outer wall of the fixing ring 10 and distributed equidistantly, the connecting rod mechanism comprises a support rod 11, and a first connecting rod 12 and a second connecting rod 13 are hinged on one end of the, bracing piece 11, head rod 12 and second connecting rod 13 constitute "Y" shape structure, head rod 12 and second connecting rod 13 are articulated with clamping piece 9 both sides limit middle part respectively, and clamping piece 9 all bonds with the junction of storage pipe 1, the junction of two adjacent clamping pieces 9 and has the sealing strip.

The working principle is as follows: insert the concrete lower floor with storage pipe 1, promote pull rod 4 downwards, can make bracing piece 11 promote head rod 12 and second connecting rod 13, thereby make clamping piece 9 rotate to storage pipe 1 outside, the clamping piece opens, can stimulate piston piece 6 through pull rod 4 and can extract the concrete thick liquid, and can make bracing piece 11 stimulate head rod 12 and second connecting rod 13, thereby make clamping piece 9 rotate to storage pipe 1 inboard, clamping piece 9 folds, it is inboard to include the stone in the concrete clamping piece 9.
