Detailed Description
The method for detecting the safety state of the construction hoist is based on the traditional construction hoist, the construction hoist has the same structure as the traditional construction hoist, and comprises a lift car 01, a dragging mechanism 02, a standard joint 03, a wall attaching device, a foundation, a fence and an electrical system, and a conventional construction hoist structure is shown in figure 2.
In the first embodiment, the structural improvement according to the present invention relates to the car 01, the standard knot 03, and the high-strength bolt assembly for connecting the same, and the rest is not described. The modification process and method of the present embodiment are described in detail below.
Referring to fig. 1, a structure of a standard knot 03 is shown, wherein the standard knot is a frame structure composed of vertical columns, transverse beams and diagonal braces, and the height of one standard knot is about 1.5 m. The standard knot 03 is provided with a rack, an inserting structure for positioning the upper end and the lower end of the standard knot, and a bolt hole structure for connecting bolts.
The car is improved, for convenience of description, a side wall of the car close to the standard knot is marked as a rear side wall, a front side wall is opposite to the rear side wall, the remaining two surfaces are a left side wall and a right side wall, and an entrance and an exit are usually arranged at the positions of the left side wall or the right side wall, namely, an entrance and an exit for getting on and getting off goods. And a guide mechanism and a driving device which are matched with the standard knot are arranged on the rear side wall, so that the lift car is vertically lifted along the standard knot.
As in the prior art, the pulling mechanism is usually driven by a gear, a rack and a variable frequency motor. The guide mechanism adopts guide wheels and guide rails on the standard knots for guiding. The rear sidewall is typically a metal material.
In the transformation of this embodiment, refer to fig. 3, carry out the secondary opening on car 01's rear side wall, the secondary opening is rectangular shape's window 11 to set up and fixed a transparent plate at this secondary opening part, this transparent plate can be transparent organic plastic board, also can choose for use as required and cost for inorganic material's toughened glass board. Meanwhile, the setting size of the window requires that the height is not less than 33 cm, the width is not less than 60 cm, and the high-strength bolt assembly for connecting standard knots can be completely covered in the width direction, so that personnel in the car can see the full view of the high-strength bolt assembly 31 through the window. In order to facilitate the observation of the people inside the car, the design height of the window is preferably 140 cm from the car floor. Of course, the specific dimensions may be adjusted on their own, depending on the actual circumstances of the elevator installation, in due course on a comfortable and pleasant basis.
In this embodiment, referring to fig. 3, for a specific mode of fixing the transparent plate, the transparent plate is fixed by a pressing bar which is also shaped like a Chinese character 'kou', and is pressed on the rear side wall to form an observation window. The viewing window is wide enough for visual observation, i.e., sufficient for a person in the car to easily view the bolt assembly at the standard node connection point.
Preferably, the high-strength bolt assembly 31 in this embodiment passes through the bolt hole on the standard knot from bottom to top, and is fastened, and when the nut on the high-strength bolt is loosened, the loosening and falling-off conditions can be timely and conveniently observed.
Example two
In the first embodiment, a fixed transparent plate is provided, that is, the position of the transparent plate in the first embodiment is fixed, so as to form a fixed window pattern. The second embodiment is an improvement on the above basis, and specifically, an openable structure is disposed at the position of the window 31 where the transparent plate is located, specifically, an openable window frame is installed at the window, and the transparent plate is fixed in the window frame. This window frame has two kinds of states, and the window frame passes through the tool to lock after by the locking, sees through the transparent plate and can play the same function with embodiment, takes place not hard up the back when discovering high strength bolt assembly, can open the window frame here, fastens the high strength bolt assembly on the standard festival, that is to say, this window can also play the effect of maintenance window.
The above two embodiments are structural improvements made to the car.
The two embodiments can be implemented independently, and the problems in the existing elevator can be basically solved after the two embodiments are implemented.
The inventor believes that, by performing a secondary technical improvement on the high-strength bolt assembly in combination with the techniques in the following embodiments, it is more convenient to find the loosening and falling-off of the screw.
EXAMPLE III
Color marking is performed on the high-strength bolt assembly 31, specifically, the high-strength bolt and the nut are respectively coated with films and identified by using different colors, and the colors of the high-strength bolt and the nut are inconsistent with the colors of the standard knots and have larger contrast. For example, when the standard knot is yellow, the high-strength bolt is sprayed red, and the nut is sprayed green, so that a large color contrast exists among the standard knot, the high-strength bolt and the nut, and therefore when an observer is in a moving car and observes the bolt through a window, the looseness or the falling-off condition of the high-strength bolt assembly can be timely found.
In fact, the car is basically in a constant speed state during ascending or descending, and by reasonably setting the running speed of the car, when the car ascends or descends (for example, 60 meters/min), an inner person is in a motion state, and a high-strength bolt assembly used for connecting a standard knot is easier to observe due to obvious color contrast. That is, the present embodiment can more easily observe the loosening or falling-off of the bolt assembly by improving the color of the bolt, which is the object to be observed.
For example, in the embodiment, the bolt assembly 31 is installed in a top-down manner, when the nut falls off, only the bolt lacks the nut, and the condition observed by an observer is only red and lacks green, so that the safety hazard is easier to be found by comparing with the previous image according to the principle of persistence of vision.
In fact, in the installation and the use of standard festival, the greasy dirt of connecting bolt subassembly is more serious, and bright-colored color is more easily found, therefore this embodiment is effectual has improved the probability that the defective junction was found.
Example four
The present embodiment is further improved on the basis of the third embodiment, in the present embodiment, the color of the standard knot is red, the colors of the bolt and the nut are blue and yellow, and the transparent plate is designed as blue transparent glass. The method has better identification, that is, the transparent glass is subjected to color setting, and the method has more obvious color identification than the third embodiment, so that the discrimination efficiency is improved.
EXAMPLE five
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the present invention may be made by those skilled in the art without departing from the spirit of the present invention, which is defined by the claims.
