Description

Technical Field

[0001] The present application relates to the technical field of power installation, and in particular to a drive installation device for a chain tensioner. Background Art

[0002] The wire tensioner, also known as the ratchet tensioner, is used to tighten the wire during the construction of overhead line installation. When using it, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the wire with the wire clamp, and then turn the special wrench. Due to the anti-reversal effect of the ratchet, gradually wind the wire rope or galvanized iron wire around the ratchet drum to tighten the wire. Fix the tightened wire on the insulator. Then loosen the ratchet first to loosen the wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the wire rope or galvanized iron wire around the ratchet drum.

[0003] At present, it is relatively cumbersome to install a tensioner powered by a motor. The corresponding bolts need to be inserted into the motor housing first and then aligned with the fixing holes on the tensioner. Finally, the motor position is fixed by turning the nuts, which is time-consuming and labor-intensive. When disassembling the motor, after unscrewing the nuts from the bolts, the bolts need to be pulled out of the motor housing and kept. The bolts kept separately are easy to lose, while the parts used for installation are not easy to lose. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] like Figure 1 As shown, in one embodiment of the present application, it is applied to a chain tensioner, and the chain tensioner includes a tensioner body 11, an adjusting member 14 and a chain 15.

[0022] The adjusting member 14 is rotatably disposed on the tensioner body 11 .

[0023] One end of the ring chain 15 is fixedly connected to the tensioner body 11. The ring chain 15 is arranged on the adjusting member 14.

[0024] The driving installation device for the chain tensioner includes a power motor 12 and a positioning assembly 13 .

[0025] The power motor 12 is disposed on one side of the adjusting member 14. A power output end of the power motor 12 is fixedly connected to the adjusting member 14.

[0026] The positioning assembly 13 is detachably arranged on the tensioner body 11 . The power motor 12 is fixedly arranged on the positioning assembly 13 .

[0027] Specifically, an adjusting member 14 for driving the chain 15 to adjust its position is provided on the tensioner body 11, and the power motor 12 is used to provide power for the adjusting member 14 on the tensioner body 11. The power motor 12 can be a motor that is easy to control. The positioning assembly 13 is fixedly connected to the power motor 12, and the positioning assembly 13 is detachably connected to the tensioner body 11.

[0028] In this embodiment, the power motor 12 is first fixedly connected to the positioning assembly 13, and then the power output end of the power motor 12 is connected to the adjusting member 14, and then the positioning assembly 13 is installed on the tensioner body 11, the positioning assembly 13 and the power motor 12 are connected to form a whole, and then the relative position of the positioning assembly 13 relative to the tensioner body 11 is fixed to fix the relative position of the fixing assembly relative to the adjusting member 14, so as to maintain the stability of the position of the positioning assembly 13 relative to the adjusting member 14, thereby providing convenience for the installation of the power motor 12 and preventing the installation parts from being lost easily.

[0029] like Figure 2 As shown, in one embodiment of the present application, it is characterized in that the positioning assembly 13 includes: a housing 131 , a plurality of bolts 132 , a plurality of nuts 133 and a plurality of limit bolts 134 .

[0030] The power motor 12 is disposed inside the housing 131 . The power motor 12 is fixedly connected to the inner wall of the housing 131 .

[0031] Each bolt 132 is disposed opposite to a nut 133. The nut 133 is disposed on the tensioner body 11. Each bolt 132 first passes through the housing 131, and then passes through the tensioner body 11, and finally the bolt 132 is threadedly connected to a nut 133 disposed on the tensioner body 11.

[0032] Each of the limit bolts 134 is disposed near one of the bolts 132. The limit bolts 134 are threadedly connected to the housing 131. One end of the limit bolt 134 penetrates the housing 131 and is inserted into the middle of the bolt 132 to limit the movement of the bolt 132 on the housing 131.

[0033] Specifically, the power motor 12 is fixedly installed inside the shell 131, and the shell 131 is arranged on a side close to the adjusting member 14, and multiple bolts 132 slide through the shell 131 and the tensioner body 11 respectively, and multiple nuts 133 are arranged on the side of the tensioner body 11 away from the driving assembly. A nut 133 is threadedly connected to each bolt 132, and each nut 133 abuts against the tensioner body 11. Multiple limit bolts 134 are arranged on the shell 131, and each limit bolt 134 is threadedly connected to the shell 131, and a limit bolt 134 is arranged on the outside of a bolt 132, and the limit bolt 134 is at least partially inserted into the bolt 132.

[0034] In this embodiment, the drive assembly is fixedly connected to the inside of the shell 131, and the shell 131 is fixedly connected to the tensioner body 11 by the cooperation of multiple bolts 132 and multiple nuts 133, and the power output end of the power motor 12 is connected to the adjusting member 14, and the multiple limit bolts 134 threaded on the shell 131 are used to limit the sliding position of the bolt 132 in the shell 131. When the shell 131 is removed from the tensioner body 11 or the shell 131 is installed on the tensioner body 11, the bolt 132 will not be detached from the shell 131, further improving the efficiency of installation and disassembly of the shell 131, and there is no need to remove the bolt 132 from the shell 131 or manually insert it into the shell 131.

[0035] like Figure 2 to Figure 3 As shown, in one embodiment of the present application, the bolt 132 includes: a bolt 132 body and a groove 132b.

[0036] The groove 132 b is formed on the outer circumferential surface of the bolt 132 . The groove 132 b is at least partially disposed in the housing 131 .

[0037] In this embodiment, a groove 132b is opened on the side wall of the bolt 132, and the limit bolt 134 is at least partially inserted into the groove 132b, so that the movable position of the bolt 132 on the shell 131 is limited by the groove 132b, so that the bolts 132 do not need to be reinserted into the shell 131 one by one when in use, saving time. The groove 132b can be annular or strip-shaped.

[0038] like Figure 3 As shown, in one embodiment of the present application, each of the limiting bolts 134 is at least partially inserted into a groove 132 b corresponding to the limiting bolt 134 .

[0039] In this embodiment, when the shell 131 is fixed on the tensioner body 11, the groove 132b is at least partially located in the shell 131 so that the limit bolt 134 is at least partially inserted into the groove 132b corresponding to the limit bolt 134, so as to limit the movement range of the bolt 132 on the shell 131 and prevent the bolt 132 from falling off the shell 131.

[0040] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
