Description

A kind of scaffold support eccentric Anti-Pressure strength test adjustable base

Technical field

The utility model relates to the technical field of scaffold detection device, in particular to a kind of scaffold support eccentric Anti-Pressure Strength test adjustable base.

Background technique

Scaffold (scaffold) refers to that construction site is worker operation and solves vertically and horizontally to transport and set up various Bracket.The generic term of architecture field refers to and is used in exterior wall, interior decoration or the higher ground that can not directly construct of layer height on construction site Side.It is plainly exactly to build a framework mainly for construction personnel works or perimeter security net is gone along with sb. to guard him and high-altitude installation component etc. up and down, Scaffold making material usually has: bamboo and wood, steel pipe or synthetic material etc..Some engineerings are also with scaffold when template use, furthermore It is also used extensively in departments such as advertising, municipal administration, traffic road bridge, mines.

Scaffold needs are used together with scaffold support, and production needs the compression strength to scaffold support after finishing Relevant detection is carried out, enable to enter sale and has better performance using the scaffold of channel, guarantees the foot hand in use Frame is all qualified products, reduces the generation of safety accident in use process, and scaffold support generally only does axial compressive strength examination It tests, but there are many case where support is by eccentric compression power in practical engineering applications, so the eccentric Anti-Pressure intensity to support carries out Detection.

In the detection process, it needs for scaffold support to be placed on bracket, then pressurization detection is carried out to scaffold support, However it is a in existing detection process, the bracket for detection is directly placed at work top, is carrying out high-intensitive pressurization When, the phenomenon that underproof scaffold support can occur bending and deformation, at this moment bracket can run-off the straight even directly collapse, It will have a direct impact on the detection accuracy of scaffold support in this way, while also bringing puzzlement to detection process.

Utility model content

The utility model is to provide a kind of scaffold support eccentric Anti-Pressure strength test adjustable base, by by bracket Limit is on work top, while bracket is slidably connected with workbench, so that the position of bracket is had controllability, in this way in foot hand When frame support compressive deformation, bracket will not improve the accuracy and safety of test there is a phenomenon where tumbling.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of scaffold support eccentric Anti-Pressure strength test adjustable base, including workbench offer on the workbench First sliding groove slidably connects bracket on the workbench, and the bracket is slidably matched with first sliding groove.

By using above-mentioned technical proposal, the side wall of steel ball and first sliding groove is inconsistent, when mobile bracket, steel ball Also it is being rotated, is further decreasing the frictional force between rack side wall and chute wall, keeping the movement of bracket more laborsaving.

Further setting: the part that the bracket is located at workbench upper end offers screw hole, the screw hole internal screw thread grafting There is bolt.

By using above-mentioned technical proposal, when bracket is moved to suitable position, bolt can be screwed, make bolt Lower end and workbench upper end it is inconsistent, bracket can be fixed, prevent bracket from position occurring when being under pressure It moves, to avoid influencing the accuracy of detection process.

Further setting: cavity is also provided in the workbench, the cavity is provided with slipping mechanism, the sliding plane Structure include the motor for being fixedly connected on cavity inner wall, the shaft being fixedly connected with motor output shaft, be fixedly connected with shaft it is convex Take turns, the second sliding slot that is provided with first sliding groove bottom end, the gag lever post being fixedly connected with second sliding slot, with hinged flexible of gag lever post Frame, the reset spring being fixedly connected with pedestal lower end side wall, the sliding block being fixedly connected with pedestal lower end, the cam and expansion bracket Inconsistent, the one end of the expansion bracket far from motor and slider side wall are hinged, and the sliding block is slidably matched with first sliding groove, described One end of reset spring is fixedly connected with bracket, and the other end is fixedly connected with chute wall.

By using above-mentioned technical proposal, start motor, motor drives shaft band moving cam to rotate, and cam supports dynamic expansion bracket It is slid back and forth in second sliding slot, expansion bracket can turn on or off during sliding, one end and branch due to expansion bracket The sliding block of frame lower end is connected, so expansion bracket can support dynamic bracket and slide back and forth, realizes the automatic sliding of bracket, need to only carry out letter Single operation is all right.

Further setting: the expansion bracket includes two groups of quarter butts and two groups of stocks, stock setting two groups of quarter butts it Between, and two groups of stocks are arranged in a crossed manner, and the hinged place of the stock passes through link block and is mutually connected, and the link block is with second Sliding slot is slidably matched.

By using above-mentioned technical proposal, the moving distance of expansion bracket can be extended, enable the rack to be slid onto farther Position keeps the range of detection more extensive.

Further setting: the side wall of the cavity is opened up there are two third sliding slot, and the two sides of the expansion bracket are and third Sliding slot is slidably matched.

By using above-mentioned technical proposal, expansion bracket can match when sliding back and forth with third sliding slot, stretch Frame can be more stable when opening and contraction, makes the movement of bracket also more steady.

Further setting: the pedestal upper end side wall is fixedly connected with mounting table.

By using above-mentioned technical proposal, it is more stable that the setting of mounting table can be such that scaffold support is positioned to, and makes foot Hand cradle support can more steadily be stablized when stress, detection process will not be kept more safe there is a phenomenon where tumbling Testing result is also more accurate simultaneously.

Further setting: magnet is fixedly connected on the mounting table.

By using above-mentioned technical proposal, magnet can generate magnetic force to scaffold support, enable scaffold support more It is stably placed on mounting table.

In conclusion the utility model has the following beneficial effects:

1, bracket can be made to be slid on the table by two different settings, while also by bracket relative limit On the table, make that bracket can be stable in the case where stress it is vertical on the table, will not there is a phenomenon where tumble；

2, the combination of stock and quarter butt can extend the moving distance of expansion bracket, make the moving distance of bracket is also opposite to prolong It is long；

3, it is more stable that the mounting table and magnet being arranged on bracket can be such that scaffold support places, in scaffold branch It will not misplace with bracket when seat stress and even tumble.
