Description

Technical Field

[0001] The invention relates to the field of inspection well construction, in particular to a tool for transporting and aligning a workpiece with a reserved hole. Background Art

[0002] Reinforced concrete inspection wells are widely used in modern urban infrastructure and renovation projects. In particular, modern environmental protection requirements are becoming increasingly stringent. Rainwater and sewage diversion projects require a large number of drainage pipes, and an inspection well needs to be set up at each distance between drainage pipes for silt removal or connecting branch pipes. Currently, they are made by on-site formwork and cast-in-place, which has defects such as inaccurate dimensions, difficult to ensure quality, complex construction and long cycles. It is no longer possible to guarantee and meet the actual production speed or quality required.

[0003] In the existing inspection well production process, the reserved hole workpiece is manually transported. When the reserved hole workpiece is large in size, it is heavy, difficult to transport, inaccurate in positioning, and time-consuming and labor-intensive to install. Summary of the Invention

The three supporting legs 20 are evenly distributed on the periphery of the center seat 18 and connected to the center seat 18. Casters are connected under each supporting leg 20, two of which are fixed casters 2 and the other is a universal caster 3. A pull rod 4 is connected to the supporting leg 20 connected to the universal caster 3.

[0022] The electromagnet fixing frame 10 is sleeved on the upper end of the column 19 , and an upper fixing lock 7 is provided on the electromagnet fixing frame 10 . The electromagnet fixing frame 10 is installed on the column 19 through the upper fixing lock 7 , and the electromagnet 6 is connected to the electromagnet fixing frame 10 .

[0023] A roller frame 11 is also sleeved on the column 19. The roller frame 11 is arranged below the electromagnet fixing frame 10. A lower fixing lock 8 is provided on the roller frame 11. The roller frame 11 is installed on the column 19 through the lower fixing lock 8. Slide grooves 22 are provided on both sides of the roller frame 11. Two sets of rollers 9 are provided on the roller frame 11. The rollers 9 include a roller seat 17, a roller shaft 16 and a roller bearing 15. An adjusting bolt 23 passes through the slide groove 22 to connect the roller frame 11 with the roller seat 17. A limiting boss 24 is integrally provided at one end of the roller shaft 16. The roller shaft 16 passes through the roller seat 17. The roller bearing 15 is connected to the other end of the roller shaft 16.

[0024] The reserved hole workpiece 5 is magnetically attracted to the electromagnet 6 , and the reserved hole workpiece 5 is supported on two supporting roller bearings 15 .

[0025] The upper fixed lock 7 and the lower fixed lock 8 have the same structure. Take the upper fixed lock 7 as an example. Figures 5 to 9As shown, the upper fixed lock 7 includes an outer sleeve 12, a screw sleeve 25, a compression spring 13 and a locking rod 14, the screw sleeve 25 being threadedly connected to the outer sleeve 12, two locking grooves 26 and two movable grooves 29 being provided on one end side wall of the screw sleeve 25, and a spring seat 28 being integrally provided in the screw sleeve 25. The end diameter of the locking rod 14 is thickened to form a step, the locking rod 14 at the step being provided in the screw sleeve 25, the other end of the locking rod 14 extending from the spring seat 28, one end of the compression spring 13 being provided on the step of the locking rod 14, and the other end being provided on the spring seat 28, two locking blocks 27 being integrally provided on the locking rod 14, the locking blocks 27 being detachably provided in the locking groove 26, and the locking blocks 27 being detachably provided in the movable groove 29.

[0026] The outer sleeve 12 of the upper fixed lock 7 is connected to the electromagnet fixing frame 10. When locked, the locking block 27 is set in the locking groove 26, and the locking rod 14 of the upper fixed lock 7 extends from the outer sleeve 12 and the electromagnet fixing frame 10 and is inserted into the adjustment hole 21 of the column 19.

[0027] The outer sleeve 12 of the lower fixed lock 8 is connected to the roller frame 11. When locked, the locking block 27 is set in the locking groove 26, and the locking rod 14 of the lower fixed lock 8 extends from the outer sleeve 12 and the roller frame 11 and is inserted into the adjustment hole 21 of the column 19.

[0028] The working process of the present invention is as follows: when working, the handheld pull rod 4 is moved to the use position of the present invention, the reserved hole workpiece 5 is hoisted to the position of the electromagnet 6, the position of the supporting wheel frame 11 is adjusted according to the size of the reserved hole workpiece 5, and locked with the lower fixed lock 8.

[0029] When the upper fixed lock 7 and the lower fixed lock 8 are in use, the locking rod 14 is pulled out and rotated 90°, the locking block 27 is set in the movable groove 29, and the electromagnet fixing frame 10 and the supporting roller frame 11 are moved to appropriate positions respectively. The locking rod 14 is rotated 90° again, the locking block 27 is set in the locking groove 26, and the locking rod 14 is extended at the same time and inserted into the adjustment hole 21 of the column 19 to fix the electromagnet fixing frame 10 and the supporting roller frame 11 respectively.

[0030] The position of the supporting wheel 9 of the reserved hole workpiece 5 is adjusted by the slide groove 22 on the supporting wheel frame 11, so that the supporting wheel bearing 15 fits with the reserved hole workpiece 5. The function of the supporting wheel bearing 15 is to reduce the resistance when the reserved hole workpiece 5 is adjusted.

[0031] After the position is adjusted, the electromagnet 6 is energized to attract the workpiece 5 with the reserved hole, and the lifting fixture is removed. The assembled inspection well outer mold is lifted to this tooling position, inserted from the tooling to the actual position where the reserved hole needs to be fixed on the outer mold, and the reserved hole is fixed to the outer mold with bolts. The electromagnet 6 is de-energized, the workpiece is released, and the outer mold is moved away. The entire operation is completed.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
