Description

Technical Field

[0001] The utility model belongs to the technical field of installation auxiliary machinery, and in particular relates to a contact-suspended hanging string installation assistant. Background Art

[0002] The contact suspension includes a contact wire, a load-bearing cable and a suspension string. The contact wire and the load-bearing cable need to be fixed by the suspension string. The suspension points of the contact wire and the load-bearing cable are increased by fixing the suspension string between the contact wire and the load-bearing cable. When the suspension string is disassembled and replaced, a contact suspension suspension suspension string installation aid is required.

[0003] However, the existing contact suspension string installation auxiliary device has some problems when in use. When installing and removing the string, the fixing of the installation auxiliary device between the contact wire and the load-bearing cable is easy to loosen, thereby affecting the operation of the string.

[0004] Therefore, those skilled in the art have proposed a contact-suspended string installation assistant to solve the above-mentioned problems. Utility Model Content

[0010] A second double-headed butterfly bolt, wherein two through holes are formed on the surface of the second double-headed butterfly bolt, and the second double-headed butterfly bolt is horizontally sleeved on a position near the top of the steel wire rope;

[0011] A fastening mechanism, wherein the fastening mechanism is fixedly mounted on the top outer wall of the hook, and the top end of the fastening mechanism is connected to the bottom end of the wire rope;

[0012] A tension lock buckle is sleeved on the top end of the steel wire rope.

[0013] Preferably, the top end of the steel wire rope passes through a through hole of the second stud butterfly bolt, passes through the interior of the tension lock buckle, and then passes back through another through hole.

[0014] Preferably, the bottom end of the steel wire rope passes through one mounting hole of the double-headed butterfly bolt, passes through the top end of the fastening mechanism, and then passes back through another mounting hole.

[0015] Preferably, the fastening mechanism includes screw 1 and screw 2, screw 1 is fixedly mounted on the top outer wall of the hook, screw 2 is located directly above screw 1, a ring is fixedly mounted on the top of screw 2, screw sleeve 1 is screwed on the outer wall of screw 1, screw sleeve 2 is screwed on the circumferential outer wall of screw 2, connecting rods are fixedly mounted on the outer walls of both sides of screw sleeve 1, the other ends of the two connecting rods are respectively fixedly mounted on the two ends of screw sleeve 2, and the same level is mounted on the outer wall of one side of the two connecting rods near the middle.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model is provided with a fastening mechanism. When the fixed suspension string is to be disassembled, a tension lock buckle is hung on the upper load-bearing cable on one side of the suspension string. The length of the steel wire rope between the tension lock buckle and the hook is adjusted according to the distance between the load-bearing cable and the contact line. Then, the contact line below is hooked by the hook. After hooking, the fastening mechanism is rotated so that the screw sleeve 1 and the screw sleeve 2 rotate on the surface of the screw rod 1 and the screw rod 2. The steel wire rope is tightened by the rotation. Then, the screws at the upper and lower ends of the suspension string are loosened, and the suspension string can be removed and replaced with a new one after removal. When hanging the string, first tighten the screws that fix the bottom end of the string to the contact line, then adjust the stress state of the string to make the string taut, then tighten the upper string screws to fix it, and then you can remove the device. After loosening the fastening mechanism, take out the hook, and then take out the tension lock. After the fastening mechanism rotates one circle, the overall adjustment height of the device is two millimeters, which is convenient for precise control of the adjustment distance. The spirit level keeps the device in a horizontal state during operation. The double-headed butterfly bolt one and the double-headed butterfly bolt two can be operated by hand, making the device more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 As shown, a contact suspension string installation assistant comprises:

[0026] A hook 1 and a steel wire rope 3, wherein the steel wire rope 3 is located above the hook 1;

[0027] A double-headed butterfly bolt 6, the surface of which has two mounting holes, and the double-headed butterfly bolt 6 is horizontally sleeved on a position near the bottom end of the wire rope 3;

[0028] A double-headed butterfly bolt 2 4, the surface of which has two through holes, and the double-headed butterfly bolt 2 4 is horizontally sleeved on a position near the top of the wire rope 3;

[0029] A fastening mechanism 2, the fastening mechanism 2 is fixedly mounted on the top outer wall of the hook 1, and the top end of the fastening mechanism 2 is connected to the bottom end of the steel wire rope 3;

[0030] The tension lock buckle 5 is sleeved on the top end of the steel wire rope 3 .

[0031] As can be seen from the above, when the suspension string needs to be removed, the tension lock buckle 5 is hung on the top load-bearing cable on one side of the suspension string, and then the distance of the wire rope 3 is adjusted by the double-headed butterfly bolt 1 6 and the double-headed butterfly bolt 2 4, and then the hook 1 is hung on the contact line at the bottom, and then the fastening mechanism 2 is rotated to tighten the wire rope 3, and then the suspension string can be removed for replacement. After the new suspension string is fixed, the device can be removed.

[0032] Specifically, the top end of the steel wire rope 3 passes through a through hole of the stud butterfly bolt 2 4 , passes through the interior of the tension lock buckle 5 , and then passes back through another through hole.

[0033] As can be seen from the above, the length of the steel wire rope 3 between the hook 1 and the tension lock buckle 5 can be easily adjusted by the double-headed butterfly bolt 2 4 .

[0034] Specifically, the bottom end of the wire rope 3 passes through one mounting hole of the stud butterfly bolt 6, passes through the top end of the fastening mechanism 2, and then passes back through another mounting hole.

[0035] As can be seen from the above, one end of the steel wire rope 3 protrudes a large section of the double-headed butterfly bolt 6, and the double-headed butterfly bolt 6 is used to facilitate the adjustment of the length of the steel wire rope 3 between the hook 1 and the tension lock buckle 5.

[0036] Specifically, the fastening mechanism 2 includes a screw rod 201 and a screw rod 202. The screw rod 201 is fixedly mounted on the top outer wall of the hook 1.
