Description

Cement mortar plain bumper

Technical field

The utility model is related to a kind of plain bumper, more specifically, it relates to a kind of cement mortar plain bumper.

Background technology

Cement mortar plain bumper is strength of cement mortar test equipment, and cam rotation is driven by synchronous motor during its work, Make vibrating mass ascending motion, fallen after being raised to definite value height, so as to produce vibration, make cement mortar in the work of multiple vibration force Use lower jolt ramming.

Existing Publication No. CN205483721U Chinese patent provides a kind of cement mortar jolt ramming stand, including preceding The lower end of pedestal and rear pedestal, preceding pedestal and rear pedestal is used for the concrete work platform that cement mortar plain bumper is fixed on to setting On, the upper end of preceding pedestal is hinged with rocking arm, and the other end of rocking arm is provided with table top, the distance between table top and preceding pedestal, backstage Seat is identical with the distance between preceding pedestal, after ensureing that rocking arm is rotated, and table top can bump against with rear pedestal to be hit.

In a pre-installation when pedestal and rear pedestal, the distance between preceding pedestal, rear pedestal must assure that with preceding pedestal, table top it Between distance it is consistent, still, when workbench is when being shorter in length than the distance between preceding pedestal and table top, cement mortar plain bumper is but It can not install, the shorter cement mortar plain bumper of rocking arm can only be customized.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of applicable different length workbench Cement mortar plain bumper.

To achieve the above object, the utility model provides following technical scheme：

A kind of cement mortar plain bumper, including preceding pedestal and rear pedestal, the upper end of the preceding pedestal are rotatably connected to rocking arm, The one end of the rocking arm away from preceding pedestal is connected with regulating arm along the sliding of rocking arm length direction, and the regulating arm is away from preceding pedestal One end is provided with to be provided with plain bumper, the rocking arm and can offseted when regulating arm slides onto setting position with regulating arm lateral wall With the fixed part of secured adjusted arm.

By using above-mentioned technical proposal, when the length of workbench is longer or shorter, first by preceding pedestal and rear pedestal Position default on the table is fixed, then regulating arm slides on rocking arm along rocking arm length direction, so that plain bumper, foreground The distance between seat is identical with the distance between preceding pedestal, rear pedestal, and then regulating arm is fixed on rocking arm by fixed part, The regulation of distance between plain bumper and rear pedestal is realized, the effect for the workbench for making cement mortar plain bumper be applicable different length is reached Really；On the other hand, in transport, regulating arm can be skidded off from rocking arm, consequently facilitating by plain bumper, preceding pedestal and rear pedestal It is separated, in order to transport.

Further, the cylindrical structure of the rocking arm, the regulating arm is plugged in rocking arm pipe and in the shaft-like knot of cylinder Structure.

By using above-mentioned technical proposal, pipe or the shaft-like structure of cylinder do not have corner angle, reduce the phenomenon of stress concentration, And then the fracture that fine crack extension is caused on reduction rocking arm, regulating arm.

Further, the fixed part includes being co-axially located at rocking arm madial wall and with rocking arm towards plain bumper direction end wall The annular groove that communicates, the rubber ring being arranged in annular groove, with annular groove madial wall it is threadedly coupled to squeeze along rocking arm length direction Press the extrusion ring of rubber ring.

By using above-mentioned technical proposal, regulating arm outer surface can be prevented effectively from and worn and torn by fixed part；On the other hand, by The frictional force for the rubber ring that rubber is made is larger, is easy to the fixation of regulating arm.

Further, the madial wall that the rubber ring is fitted with regulating arm is provided with coarse for increasing rubber ring madial wall The anti-skidding burr of degree.

By using above-mentioned technical proposal, after secured adjusted arm, further prevent regulating arm in rocking arm along its length Direction is slided, with more preferable secured adjusted arm.

Further, the extrusion ring and lateral wall of one end is circumferentially provided with several and is easy to turn outside the annular groove The rotation groove of dynamic extrusion ring.

By using above-mentioned technical proposal, the setting of groove is rotated, operating personnel can be easy to apply extrusion ring and rotated Power, so that rubber ring is fully extruded, it is more serious that rubber ring is extruded, then rubber ring is bigger to the conflict power of regulating arm, enters one Regulating arm is fixed step.

Further, the madial wall of the extrusion ring, which is rolled, is equipped with several while the rolling offseted with regulating arm lateral wall Pearl.

By using above-mentioned technical proposal, several balls can reduce extrusion ring rocking on regulating arm, in order to Extrusion ring docks annular groove upper screwed hole.

Further, the extrusion ring away from the end wall of rocking arm be coaxially arranged with madial wall and regulating arm lateral wall offset with Clean the cleaning circle of regulating arm lateral wall.

By using above-mentioned technical proposal, when regulating arm is slided into rocking arm pipe, cleaning circle can be by the outside of regulating arm Glue sand cleaning on wall, is entered in rocking arm pipe with reducing glue sand.

Further, the fixed part is included through the fixing hole being arranged on rocking arm tube wall and fixing hole madial wall spiral shell The check lock lever of line connection.

By using above-mentioned technical proposal, when needing secured adjusted arm, by turn check lock lever to push against outside regulating arm Side wall, so as to realize the regulation of regulating arm.

Further, the check lock lever sets flexible direction and check lock lever length direction towards the end wall in regulating arm direction Consistent elastic component.

By using above-mentioned technical proposal, after check lock lever is screwed, elastic component is compressed, and elastic component has to check lock lever all the time Have along its axial abutting power, released on the fixing hole madial wall to prevent check lock lever.

Further, the preceding pedestal it is horizontally disposed have be provided with one end and rib on rib type pipe, the rear pedestal Wall slip is connected so that the rib type post that preceding pedestal is generally aligned in the same plane with the lower end wall of rear pedestal on the inside of type pipe.

By using above-mentioned technical proposal, when the upper surface out-of-flatness of workbench, the lower end wall of preceding pedestal and rear pedestal Remain to keep at grade, so that the upper surface of the lower surface of shake table and rear pedestal is completely attached to, to reduce to vibration The damage of the lower surface of platform.

In summary, the utility model has the advantages that：It is flexible in rocking arm by regulating arm and fixed The fixation in portion, so as to realize the effect for the workbench for being applicable different length；In the process for sliding regulating arm to the tube wall of rocking arm In, cleaning circle carries out automated cleaning to regulating arm lateral wall.
