DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the utility model, the portable and detachable contact measurement suspension wire bracket device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1~Figure 4 As shown, a portable and detachable contact measurement suspension wire bracket device includes a support sleeve 1 and a horizontal sleeve 2. A flange is fixed at the bottom end of the support sleeve 1. A vertical rod 13 is slidably connected in the support sleeve 1. The vertical rod 13 can also rotate axially in the support sleeve 1. The upper end of the vertical rod 13 is connected to a right-angle elbow provided at the end of the horizontal sleeve 2. The other end of the horizontal sleeve 2 is slidably connected to a cross bar 21. The vertical rod 13 can be fixed in the support sleeve 1, and the cross bar 21 can be fixed in the horizontal sleeve 2. A fixed shaft is arranged on the sleeve 1, and a steel wire drum 3 is rotatably connected on the fixed shaft. A rocker is arranged on the outer side of the steel wire drum 3 at a position away from the axis. A braking mechanism is arranged on the steel wire drum 3 to limit the rotation of the steel wire drum 3. A first fixed pulley 32 is installed on the right-angle elbow. A second fixed pulley 33 is installed on the end of the cross bar 21 away from the horizontal sleeve 2. A steel wire 31 is wound on the steel wire drum 3, and the end of the steel wire 31 is successively wound around the first fixed pulley 32 and the second fixed pulley 33 and then detachably connected to a hammer ball 35.

[0027] In this embodiment, the support sleeve 1 is made of a 1000mm long Φ73 seamless steel pipe with a wall thickness of 5.18mm, which is welded to the flange by resistance welding. Four 3mm thick triangular steel plates are used as ribs around the flange for reinforcement. A Φ22 hole is opened 100mm below the upper end of the support sleeve 1, and an M20 nut is welded at the hole mouth. A Φ20 locking bolt 12 is installed to fasten the support sleeve 1 and the vertical rod 13. A 100mm long steel bar is vertically welded to the head of the locking bolt 12 to facilitate loosening and tightening the bolt. A 70mm long Φ20 steel bar is welded to the upper end of the support sleeve 1 as a fixed axis, and a through hole is punched at one end of the steel bar for installing and fixing the wire reel 3 through a stainless steel single bead pull ring pin 4. Figure 7 and Figure 8 As shown, the support sleeve 1 is welded with a steel bar of 80 mm in length above the fixed axis and parallel to the fixed axis as a fixed rod 37 , and a brake plate 38 is rotatably connected to the fixed rod 37 .

[0028] The horizontal sleeve 2 is made of a 1200mm long Φ73 seamless steel pipe with a wall thickness of 5.18mm. The steel pipe is cut into two sections by marking along the steel pipe axis at 45 degrees at 200mm from one end. One section is rotated 180° radially, and then the two cut surfaces are aligned and welded to form a 90° elbow joint. A 5mm triangular steel plate is used as a rib plate for reinforcement at the joint. A Φ12 through hole is punched at 100mm from each end of the manufactured horizontal sleeve 2. The vertical rod 13 and the horizontal rod 21 are both made of a 1.1m long Φ60 seamless steel pipe with a wall thickness of 4.22mm. A total of ten holes with an interval of 100mmΦ12 are opened in the through holes of the steel pipe, which are the first pair of through holes 14 and the second pair of through holes 22.

[0029] like Figure 7 As shown, a gear 36 is welded on the inner side of the homemade steel wire drum 3 coaxially with the steel wire drum 3, and the steel wire drum 3 can be replaced by a manual winch on the market. The connecting ring 34 can use a key ring, which is tied to one end of the steel wire 31 for convenient hanging of the hammer ball 35, which is a 500-gram small hammer ball, used to prevent the steel wire 31 from tangling during the lowering process.

[0030] Two fixed pulleys, two Φ10 stainless steel single bead pull ring pins 4 with a length of 150 mm, two Φ10 stainless steel single bead pull ring pins 4 with a length of 100 mm, one Φ4 stainless steel single bead pull ring pin 4 with a length of 40 mm and four expansion screws 11 are used in conjunction. Figure 3 and Figure 4 As shown, the support sleeve 1 is fixed to the retaining wall of the shaft or station for communication measurement with expansion screws 11, the vertical rod 13 is inserted into the support sleeve 1, and a Φ10 stainless steel single bead pull ring pin 4 with a length of 100 mm is inserted into the first pair of through holes 14 and abuts against the upper end of the support sleeve 1. Figure 5As shown, the horizontal sleeve 2 is installed above the vertical rod 13, and the vertical rod 13 and the horizontal sleeve 2 are inserted and fixed by a Φ10 stainless steel single-bead pulley pin 4 with a length of 150 mm and a first fixed pulley 32. Figure 6 As shown, a Φ10 stainless steel single-bead pull ring pin 4 with a length of 150 mm and a second fixed pulley 33 is passed through the opening at one end of the cross bar 21, and the other end of the cross bar 21 is inserted into the horizontal sleeve 2 and fixed with a Φ10 stainless steel single-bead pull ring pin 4 with a length of 100 mm.

[0031] After the bracket is assembled, Figure 7 and Figure 8 As shown, the wire reel 3 with the wire 31 is mounted on the fixed shaft above the support sleeve 1 and fixed with a Φ4 stainless steel single bead pull ring pin 4 with a length of 40 mm. The wire 31 with the connecting ring 34 is passed around the two fixed pulleys on the bracket, and a 500g small hammer ball is hung on the connecting ring 34.

[0032] When in use, loosen the brake plate 38, rotate the wire drum 3, lower one end of the wire 31 with a 500-gram small hammer ball to the bottom of the shaft, replace the small hammer ball, hang a special hammer ball for contact measurement (usually 10 kg), adjust the lowering height and position of the wire 31, immerse the special hammer ball in the damping fluid, and finally tighten the locking bolt 12 to clamp the brake plate 38 on the gear 36 to prevent the wire 31 from swinging and sliding down.

[0033] The hanging steel wire bracket device of this embodiment can adjust the height range of the bracket to 1.22m~2.02m and the horizontal length range to 1.2m~1.9m by adjusting the position of the stainless steel single bead pull ring pin 4 of Φ10 length 100mm inserted in the vertical rod 13 and the horizontal rod 21. By loosening the locking bolt 12 at the upper end of the support sleeve 1, rotating the vertical rod 13, and the horizontal sleeve 2 swinging accordingly, the direction of the hanging steel wire 31 can be adjusted, and the rotation range is 0°~360°. The steel wire 31 is pre-wound onto the steel wire drum 3, and the steel wire drum 3 is installed on the support sleeve 1 of the bracket when in use, which is convenient for the vertical placement of the steel wire 31, and solves the technical problem that the steel wire cannot be absolutely vertical when the steel wire is rolled up and tied in a knot during the hanging process of the connection measurement, and the steel wire 31 can be reused. It is simple to make, convenient to obtain materials, compact and light, simple to install, and highly efficient, and has extremely wide promotion value.
