Detailed Description

The following detailed description is to be read in connection with the specific embodiments and the drawings:

this embodiment specifically provides a housing construction engineering's construction platform, including base 1, operation panel 2, universal wheel 6 and guardrail 5, universal wheel 6 installs in base 1 bottom, and operation panel 2 installs above base 1. In the concrete implementation process, as shown in fig. 1-2, in order to better improve the safety and reliability of the construction platform,still be equipped with limit structure in the bottom of aforementioned base 1, limit structure can restrict the wheel of universal wheel 6 is not wrench movement wantonly, makes universal wheel 6 not roll wantonly promptly, provides further limited function for the universal wheel 6 that itself has locking function, prevents that this construction platform from when reacing operating position, the accidental removal. For this position limiting design, the skilled person can do this in a number of ways, and this embodiment recommends a very simple and effective design: limiting grooves 9 with the same number as the universal wheels 6 are arranged at the position, right opposite to the universal wheels 6, of the bottom of the base 1, and as shown in figures 4-5, the cross sections of the limiting grooves 9 are oval and gradually reduced from bottom to top. The universal wheel 6 comprises a mandrel 8 and a wheel

The support of type, dabber 8 can install with reciprocating in base 1 and can fix the setting when moving a certain position last, and install with rotating dabber 8 bottom in the top surface of support to make the support can wind dabber 8 free rotation, the wheel is installed to the support internal rotation, when moving to given position on the dabber 8, the left and right sides of wheel slides just to the V type side angle 21 inside jamming of the left and right sides of spacing groove 9, V type side angle 21 is oval enough flat such inner wall corner of the similar V type that forms in fact. For the design, the essential principle is that the arc characteristic of the tire tread of the wheel is in sliding fit with the arc surface inside the limiting groove 9, so that when the mandrel 8 moves upwards, the wheel is gradually contacted with the inner surface of the limiting groove 9, but because the support is in rotating fit with the mandrel 8, the whole formed by the wheel and the support can self-adaptively rotate, and finally, under the oval structure of the cross section of the limiting groove 9, the wheel can self-adaptively slide to two ends of the long axis of the oval, namely, the V-shaped side corners 21 on the left side and the right side of the limiting groove 9, at the moment, the position is unchanged because the mandrel 8 is fixed again, the wheel is limited in the V-shaped side corners 21, the whole structure formed by the wheel and the support cannot easily rotate, and the whole construction platform cannot easily move and deviate after being in place. In order to make the wheel more restrained, the aforementioned V-shaped side corner 21 may be an inclined groove 1 opened directly at both sides of the stopper groove 90。
