Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is further described:

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the present utility model discloses a revolvable operation platform suitable for elevator counterweight installation, supporting upright column 1, bottom support 2, horizontal pick rod 3 , top support 4, end pick rod 5, diagonal tie rod 6, vertical railing 7, end railing 8, horizontal railing 9, fixed crossbar behind the wall 10, rotary fastener 11, right angle fastener 12, pick rod bolt 13 , expansion bolts 14, steel collars 15, limit bolts 16, expanded metal mesh 17, semicircular claws 18, wire rope knot ring 19, reinforcing ribs 20.

A horizontal frame is formed by the support column 1 , the horizontal pick rod 3 , the end pick rod 5 , the vertical railing 7 , the end railing 8 and the horizontal railing 9 through the combination of steel pipe fasteners. Specifically, the support column 1 and the vertical railing 7 are both vertically arranged and parallel to each other; the horizontal pick-up rod 3 and the horizontal railing 9 are arranged in parallel up and down, and the axis of the horizontal pick-up rod 3 is perpendicular to the combination of the support column 1 and the vertical railing 7 to form The end pick rod 5 and the end rail 8 are arranged in parallel up and down, and the axis of the end pick rod 5 is perpendicular to the plane formed by the combination of the horizontal pick rod 3 and the horizontal rail 9. Through the above arrangement, the design of the horizontal frame is completed, thereby making the horizontal frame a whole.

When in use, push the horizontal frame into the elevator shaft through the door opening of the elevator as shown in Figures 1 and 2. The upper end of the top support 4 is U-shaped, and the lower end of the top support 4 is provided with vertical screw holes. An external thread is provided on the upper end of the supporting column 1 , and the supporting column 1 is threadedly connected to the vertical threaded hole at the lower end of the top support 4 . The upper end of the top support 4 clamps and fixes the upper cavity of the door opening, so that the upper end of the support column 1 is fixed by the top support 4 .

The lower end of the support column 1 is fixed by the bottom support 2 . Expansion bolts 14 are connected and arranged on the bottom support 2 , and then the bottom support 2 is fixed on the lower floor of the door opening through the expansion bolts 14 . The lower end of the support column 1 is fixed to the fixed base by means of plugging, welding or bolting. In this way, the vertical fixing of the supporting column 1 is completed by the fixing base and the top support 4 . In turn, the supporting column 1 is urged to complete the horizontal suspension fixation to the horizontal frame. The expanded metal mesh 17 is fixed to the horizontal pick-up rod 3 of the horizontal frame through the semicircular claws 18, and the overall installation of the horizontal frame is completed.

When the above-mentioned horizontal frame is in use, the horizontal railing 9 plays a protective role for the operator, and is also one of the important fixing parts forming the horizontal frame. Therefore, in actual operation, the vertical distance between the horizontal railing 9 and the horizontal pick rod 3 can be set to be greater than 1.2 meters. net as a safety measure for the horizontal frame. The operator can complete the counterweight installation of the elevator through the horizontal frame.

The installation of the fixed cross bar 10 and the diagonal stay bar 6 behind the wall is to strengthen the fixed connection of the horizontal frame. Specifically, after the fixed crossbar 10 behind the wall is fixedly connected to the support column 1 through the right-angle fastener 12, both ends of the fixed crossbar 10 behind the wall extend beyond both sides of the horizontal frame. As shown in FIG. 2 , the two ends of the fixed crossbar 10 behind the wall are abutted on the inner wall of the door opening facing away from the horizontal frame. In this way, the fixing of the support column 1 is structurally enhanced by the fixing crossbar 10 behind the wall, so as to realize the overall structural enhancement of the horizontal frame, and the connection of the horizontal frame is more stable.

Similarly, the two ends of the oblique stay rod 6 are fixedly connected to the fixed crossbar 10 behind the wall and the end pick rod 5 through the steel collar 15 respectively. In this way, the end pick rods 5 can be further fixed by the inclined tie rods 6, thereby enhancing the structural stability of the cantilevered section of the horizontal frame away from the door opening, and further stabilizing the connection of the horizontal frame.

In this case, the horizontal pick rod 3 can also be fixedly connected to the base by the pick rod bolts 13, which does not affect the layout of the horizontal frame in this case. For example, limit bolts 16 are arranged at the connection between the end pick rod 5 and the vertical railing 7; in order to facilitate the lifting of the horizontal frame, a wire rope knot ring 19 is fixedly arranged at the upper end of the vertical railing 7; 2 and the top support 4 are structurally reinforced to increase the welding reinforcement rib 20; for example, when the top support 4 and the support column 1 are connected by sliding up and down, a positioning bolt 21 is added on the top support 4, and the positioning bolt 21 penetrates the top support 4. And the support column 1 to realize the axial positioning and fixed connection between the top support 4 and the support column 1 . Designs such as these are designed to diversify the installation methods of the horizontal frame and make it more powerful.

Except for the non-removable expansion bolts of the operating platform, the rest can be recycled and reused, and it has a good economical type. At the same time, the expanded metal mesh can be fixedly connected with the horizontal frame through the semicircular jaws, which makes the installation more convenient. It should be noted that both the rotary fastener and the right-angle fastener belong to the steel pipe fastener, which is a common connector for connecting steel pipes in the industry.

The above are only preferred embodiments of the present invention, and are not limited to the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the within the protection scope of the present invention.
