Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric power equipment, in particular to an installer for an anti-vibration hammer on a transmission line. Background Art
[0002] On high-voltage overhead lines, a small hammer is often hung on the conductors near the insulators on both sides. This hammer is called an anti-vibration hammer, which is designed to reduce the vibration of the conductors caused by wind. The poles of high-voltage overhead lines are high and the span is large. When the conductors are affected by wind, they will vibrate. When the conductors vibrate, the working conditions at the place where the conductors are suspended are the most unfavorable. Due to multiple vibrations, the conductors will suffer fatigue damage due to periodic bending.
[0003] There are two ways to fix the anti-vibration hammer to the conductor: bolt type and pre-twisted type. Among them, the pre-twisted type is more basic and commonly used. Figure 1 As shown, the pre-twisted anti-vibration hammer includes two hammer heads, one large and one small, which are connected by a connecting rod. A hammer hook is provided in the middle of the connecting rod to hook the wire. A plurality of pre-twisted wire spaced protrusions are provided on the outer side of the hammer hook. The anti-vibration hammer is connected to the wire through the pre-twisted wire, which is a prefabricated spiral metal rod with a certain elasticity. The installation process is to first hook the guide wire with the hammer hook, then place the pre-twisted wire between the pre-twisted wire spaced protrusions, and then wrap the two ends of the pre-twisted wire around the outer side of the wire. Multiple pre-twisted wires can effectively connect the anti-vibration hammer with the wire.
[0004] In the early stage of line erection, the conductor is not energized, and the operator can manually install the anti-vibration hammer. During the use of the line, the anti-vibration hammer may be damaged or slipped away from its installation position due to factors such as vibration, and the anti-vibration hammer needs to be installed again. However, at this time, the conductor is energized, and the cost of disconnecting the conductor is high. In many cases, live installation is required. Live installation requires the operator to use non-conductive devices such as insulating rods to install the anti-vibration hammer on the ground or on the transmission tower without touching the conductor.
[0005] In some prior arts, in order to facilitate the installation of the anti-vibration hammer, the structure of the hammer hook is changed, and a pre-twisted wire fixing device is established on the hammer hook to pre-fix the pre-twisted wire on the hammer hook of the anti-vibration hammer. For example, a plurality of through holes passing through both sides of the hammer hook are arranged at intervals on the hammer hook, and the pre-twisted wire is inserted into the through holes, and then the two are sent to a high altitude together. After the hammer hook hooks the wire, the hammer hook is tightened downward with an insulating rod to temporarily fix the anti-vibration hammer on the hammer hook, and then the pre-twisted wire is wound onto the wire through the insulating rod with an "r"-shaped hook at the end.
[0006] The anti-vibration hammer is a commonly used tool in power supply lines and is used in large quantities. Changing the structure of the anti-vibration hammer will increase its structural complexity, which will in turn increase material costs, processing costs, etc. Summary of the invention
[0007] The purpose of the present invention is to provide an eccentric anti-vibration hammer installer, which can realize the installation of a pre-twisted anti-vibration hammer under power, and has the characteristics of simple structure, safe operation and high installation efficiency.
[0008] The technical solution of the present invention is:
[0009] The utility model relates to an eccentric anti-vibration hammer installer, which is used for installing the anti-vibration hammer on a conductor when the conductor is not powered off.
[0010] The anti-vibration hammer includes two hammer heads, which are connected by a connecting rod. A hammer hook is provided in the middle of the connecting rod. The hammer hook includes a handle and a hook. A connecting rod sleeve is provided at the end of the handle. The connecting rod sleeve is sleeved on the connecting rod. The hook is hooked on the conductor. Pre-twisted wire spacing protrusions are provided at intervals on the back of the hook. The pre-twisted wire is arranged between the pre-twisted wire spacing protrusions. After installation, both ends of the pre-twisted wire are wrapped around the conductor.
[0011] The eccentric anti-vibration hammer installer comprises a base, a pressure hook and a rotating shaft. The base comprises a base plate and a hook-shaped seat arranged on the base plate. The upper end of the hook-shaped seat is provided with a base shaft sleeve.
[0012] The hook seat is an arc groove on the base plate, the arc groove is the hook part of the hook seat, a groove wall of the arc groove extends upward to form the handle of the hook seat, and the base sleeve is arranged at the upper end of the handle of the hook seat. The arc groove matches with the connecting rod sleeve of the anti-vibration hammer, and the outer diameter of the connecting rod sleeve matches with the inner diameter of the arc groove.
[0013] The pressing hook is a hook-shaped plate-like structure, and a pressing hook sleeve is provided at the lower end of the pressing hook. The pressing hook is composed of an arc-shaped hook portion and a straight plate handle portion, and the ends of the multiple pre-twisted wires are spaced apart to form an arc-shaped contour, and the contour of the pressing hook portion matches the arc-shaped contour formed by the ends of the pre-twisted wires. The pressing hook sleeve is provided at the end of the pressing hook handle portion.
[0014] Specifically, a notch is provided in the middle of the base sleeve, the width of the pressure hook sleeve matches the width of the notch, the pressure hook sleeve can be inserted into the notch of the base sleeve, and the axis of the base sleeve and the axis of the pressure hook sleeve are parallel to each other.
[0015] The rotating shaft includes a main section and an eccentric section. The diameter of the eccentric section is larger than the diameter of the main section. The axis of the eccentric section is parallel to the axis of the main section. On a plane perpendicular to the axis of the main section, the projection circle of the main section contains or is inscribed in the projection circle of the eccentric section. The axis of the main section does not coincide with the axis of the eccentric section. The main section is rotatably connected to the base sleeve, and the eccentric section is rotatably connected to the pressure hook sleeve.
[0016] The hook-shaped seat and the pressure hook are connected by a rotating shaft, the main section of the rotating shaft is connected to the base sleeve in rotation, and the eccentric section of the rotating shaft is connected to the pressure hook sleeve in rotation. When in use, the connecting rod sleeve of the anti-vibration hammer is placed in the arc groove of the hook-shaped seat, and the handle of the hammer hook fits the handle of the hook-shaped seat. In the length direction of the anti-vibration hammer hook handle, the length from the lower end of the hook-shaped seat to the axis of the base sleeve is L1; when the handle of the pressure hook is parallel to the anti-vibration hammer hook handle, in the length direction of the anti-vibration hammer hook handle, the length from the upper end of the pressure hook to the axis of the pressure hook sleeve is L2; the distance between the axis of the main section of the rotating shaft and the axis of the eccentric section is D. By rotating the rotating shaft, the distance between the lower end of the hook-shaped seat and the upper end of the pressure hook can be changed between L1+L2-D and L1+L2+D. The spacing of L1+L2+D allows the anti-vibration hammer to enter between the pressure hook and the hook-shaped seat in the opening direction of the C-shaped structure formed by the pressure hook and the hook-shaped seat. When the spacing between the lower end of the hook-shaped seat and the upper end of the pressure hook is between L1+L2-D and L1+L2, the anti-vibration hammer is clamped by the pressure hook and the hook-shaped seat and cannot escape.
[0017] When installing the anti-vibration hammer, first rotate the shaft so that the distance between the lower end of the hook seat and the upper end of the pressure hook reaches L1+L2+D. Place the connecting rod sleeve of the anti-vibration hammer in the arc groove, fit the handle of the hammer hook of the anti-vibration hammer to the handle of the hook seat, place the pre-twisted wire between the pre-twisted wire spacing columns on the pressure hook, and then snap the pressure hook onto the hook of the anti-vibration hammer hook, rotate the shaft to reduce the distance between the lower end of the hook seat and the upper end of the pressure hook, thereby tightening the anti-vibration hammer. At the same time, tighten the pre-twisted wire between the pressure hook and the hook of the anti-vibration hammer hook. Lift the eccentric anti-vibration hammer installer and the anti-vibration hammer together to the conductor with an insulating rod, and hook the hammer hook of the anti-vibration hammer on the conductor. Use an insulating rod with an "r"-shaped hook at the end to wind the pre-twisted wires at both ends of the eccentric anti-vibration hammer installer onto the conductor.
[0018] The end of the main body section is provided with a shifting rod which is perpendicular to the main body section, and the side of the base plate away from the hook-shaped seat is provided with an insulating rod.
[0019] After the pre-twisted wire is wound onto the conductor, use an insulating rod to push the lever to expand the distance between the lower end of the hook seat and the upper end of the pressure hook to L1+L2+D, and remove the anti-vibration hammer from the eccentric anti-vibration hammer installer. The anti-vibration hammer is then fixed to the conductor by the pre-twisted wire. At this point, the anti-vibration hammer is installed.
[0020] The function of the insulating rod on the side of the base away from the hook seat includes lifting the eccentric anti-vibration hammer installer onto the conductor, and pulling down the insulating rod when winding the pre-twisted wire and toggling the lever to maintain the relative position relationship between the eccentric anti-vibration hammer installer and the conductor.
[0021] Specifically, the pressing hook and the hook-shaped seat form a C-shaped structure, the rotating shaft is arranged in the middle of the C-shaped structure, and a tension spring is arranged between the pressing hook and the base plate to open the C-shaped structure formed by the pressing hook and the hook-shaped seat.
[0022] Specifically, the pressing hook rotates around the rotating shaft to open the C-shaped structure.
[0023] The tension spring can promote the opening of the C-shaped structure, thereby facilitating the removal of the anti-vibration hammer from the eccentric anti-vibration hammer mounter.
[0024] The insulating rod comprises a connecting column and a rod body, wherein the connecting column and the rod body are threadedly connected. The insulating rod is detachable and easy to carry.
[0025] The axis of the connecting column forms an angle of 30° with the base plate.
[0026] In a solution where a tension spring is not provided, the inclined connecting column can cause the pressing hook to move obliquely upward when the connecting column is lifted vertically upward, thereby facilitating the escape of the anti-vibration hammer.
[0027] The advantages and positive effects of the present invention are as follows: due to the adoption of the technical solution, the installation of the anti-vibration hammer can be completed when the conductor is energized, the structure of the anti-vibration hammer does not change, the operation is safe, and the structure is simple.
