Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-2, the utility model discloses a vibrating table, it is fixed on by concrete prefabricated member mould (not shown), this type of mould is mainly applied to the preparation of wet concrete prefabricated member. The vibration table comprises a support member 1, a vibration assembly 2, a base 3 and an elastic member 4.

The supporting piece 1 is used for supporting a prefabricated part mould and consists of two parts, namely a supporting plate 11 and a polygonal frame 12 formed by welding or connecting sectional materials through bolts from top to bottom, so that the prefabricated part mould is convenient to manufacture, and the supporting plate and the polygonal frame are connected into a whole through welding or bolts.

The vibration assembly 2 generally includes a motor and a vibration element, which are detachably coupled to the bottom or side of the frame 12 to generate a vibration source and are transmitted to the support plate 11 through the frame 12, so that the wet concrete in the mold is uniformly distributed by discharging air after being vibrated, and the vibration assembly 2 is bolted by punching holes at the side or bottom of the frame 12, is conveniently mounted and dismounted, is suitable for field assembly, and can be adjusted in mounting position and number of the vibration assembly 2 by empirical calculation according to the area of the support plate 11.

Base 3 can be concrete base, makes things convenient for the on-the-spot direct pouring to form, need not the outside transportation, and base 3 be massive and be a plurality of, and interval distribution raises frame 12 in the bottom of frame 12 apart from ground height, keeps somewhere out the space that supplies vibration subassembly 2 to install, the bottom of being convenient for is dismantled the installation.

Elastic component 4 sets up between base 3 and frame 12, when frame 12 takes place the vibration because of vibration subassembly 2, plays the cushioning effect, avoids taking place horizontal migration with base 3 hard contact, seriously, slippage play base 3 to reduce base 3 because of the vibration with the vertical direction ground to support piece 1 ground reaction force, influence the distribution of concrete. In the preferred embodiment, the elastic member 4 is a rubber pad, and is clamped and fixed with the base 3 by the gravity of the frame 12, the structure is simple, the assembly is convenient, the rubber pad needs to cover all the contact areas of the frame 12 and the base 3, the vibration conduction between the frame 12 and the base 3 is weakened, and the frame 12 is effectively prevented from being separated from the base 3 due to the fact that the rubber pad has good friction. Compared with a traditional spring buffer structure, the spring buffer structure needs to be fixedly connected through bolts and is arranged at four corners, so that the spring buffer structure is not suitable for a large-scale vibrating table.

The rubber pad's thickness undersize, the buffering effect is not good, and thickness is too big, is unfavorable for the installation, and extravagant material. In the preferred embodiment, the thickness of the rubber pad is t, which satisfies that t is more than 5mm and less than 10mm, so that the rubber pad has a better buffering effect and saves materials.

In one embodiment, the frame 12 is assembled by an outer frame 121 and an inner frame 122 for conducting vibration, the inner frame 122 includes at least one longitudinal beam 123 connecting the outer frame 121 and a plurality of transverse beams 124 disposed between the outer frame 121 and the longitudinal beam 123, the longitudinal beam 123 and the transverse beam 124 are welded and fixed to each other, and after cross-connection, the vibration assembly 2 can be effectively transmitted to the whole support plate 11 through the inner frame 122 no matter where it is installed.

The specific distribution of the oscillating assemblies 2 is described with reference to the following two embodiments.

The first embodiment is as follows: the vibrating assemblies 2 are arranged at the bottom of the frame 12, and are arranged at the intersections of the longitudinal beams 123 and the cross beams 124, and can be arranged at intervals, and one vibrating assembly 2 can also be arranged at each intersection.

Example two: the vibrating component 2 is arranged on the side face of the outer frame 121 and is arranged near one end of the cross beam 124, and due to the incomplete rod piece of the cross beam 124, the vibrating effect is not good in transmission, so that the vibrating component 2 is arranged at the intersection of each cross beam 124 and the outer frame 121, the vibration of the whole supporting plate 11 is uniform, the efficiency is higher, and the vibrating component can be distributed at intervals.

Preferably, in the two embodiments, the arrangement of the vibration assemblies 2 may also be symmetrically arranged, so that the vibration effect is uniform, and the occurrence of vibration frequency difference, which results in uneven distribution of concrete, is avoided.

In one embodiment, the vibration frequency of the vibration component 2 is adjustable, the adjustment range is 3600-7200 Hz, and the efficiency is higher through frequency conversion adjustment and high-frequency vibration.

In one embodiment, the thickness of the supporting plate 11 is larger than 12mm, so that the strong structural strength is improved, and a plurality of prefabricated part molds can be conveniently arranged above the supporting plate for vibration island.

In one embodiment, the frame 12 is made of H-section steel, which is a standard piece that is convenient to manufacture on site.

The application provides a pair of shaking table presss from both sides tight fixed elastic component 4 through frame 12 and base 3, and vibrates subassembly 2 and be detachably connected, more current spring buffer structure, makes things convenient for on-the-spot dismantlement and installation to elastic component 4 is the rubber pad, can tailor according to base 3's structure, and the wide range of coverage is fit for large-scale shaking table.

It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
