Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting, in particular to a hoisting clamp for producing electric poles. Background Art

[0002] Utility poles are poles used to carry electric wires and are an important part of the infrastructure for power supply and communications. Their presence can be traced back to early Chinese rural areas and fields. With the development of technology, wooden poles have gradually been replaced by steel and reinforced concrete because these materials are more durable and adapt to the needs of modern power engineering. However, due to their hollow structure, they are often clamped at both ends during hoisting and installation, which makes them prone to breakage. This paper proposes a structure that prevents utility poles from breaking during hoisting. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a hoisting fixture for producing electric poles, which solves the above problems.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a lifting fixture for electric pole production, including a frame, and also including: a positioning assembly, used to prevent the electric pole from breaking during lifting; the positioning assembly includes a connecting rod, a sleeve and a slide, the connecting rod is slidably connected to the frame, the sleeve is fixedly connected to the connecting rod, the slide is slidably connected in the sleeve, and a damping rubber strip is provided at the connection between the slide and the sleeve.

[0005] Beneficial effects

[0006] The utility model provides a lifting fixture for electric pole production, which has the following beneficial effects compared with the prior art:

[0007] The user moves the device so that the hollow electric pole is close to the lining plate, and then starts the motor, so that the screw rod fixedly connected to the motor output shaft starts to rotate, and the slide A threadedly connected to the screw rod starts to slide along the connection between it and the frame. At this time, the connecting rod fixedly connected to the slide A starts to slide synchronously, so that the connecting rod pushes the sleeve fixedly connected to it to enter the inside of the electric pole, and pushes the slide to start contacting the top rod. At this time, with the cooperation of the top rod, the positioning hole starts to slide into the sleeve. At the same time, due to the damping rubber strip at the connection, the slide can slide into the sleeve at a uniform speed. At this time, the slide starts to drive the top rod A hinged on it to slide synchronously, so that the top rod A starts to push the arc plate hinged to it, so that the other side of the arc plate The slider of the sliding connection begins to slide along the connection between it and the arc plate. At this time, the arc plate begins to move linearly at a uniform speed under the action of the top rod A and the top rod B, so that multiple arc plates begin to move synchronously and fit tightly against the inner wall of the pole. When the slide contacts the bottom of the sleeve groove, multiple arc plates begin to fit tightly against the inner wall of the groove synchronously, so that the pole is fixed by cooperating with multiple arc plates to prevent shaking during hoisting and avoid breaking of the pole due to the use of two-end fixing method. At the same time, when the top rod enters the positioning hole, the high-damping rubber ring provided on the positioning hole can increase the damping of its sliding. Therefore, when the sleeve slides in the opposite direction after the hoisting is completed, the slide can be limited by the top rod, thereby assisting the slide to slide out and reset in the sleeve.

DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0015] See also Figures 1 to 4 , provided in one embodiment of the present utility model, is a hoisting fixture for producing electric poles, comprising a frame 101, and further comprising:

[0016] Positioning assembly 2, used to prevent the pole from breaking during hoisting;

[0017] The positioning assembly 2 includes a connecting rod 201, a sleeve 202 and a slide 203. The connecting rod 201 is slidably connected to the frame 101, the sleeve 202 is fixedly connected to the connecting rod 201, and the slide 203 is slidably connected in the sleeve 202. A damping rubber strip is provided at the connection between the slide 203 and the sleeve 202.

[0018] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific connecting rod 201 described in the above embodiments. For example, the connecting rod 201 is made of high-hardness material. The purpose of this setting is to prevent it from breaking under stress through this setting.

[0019] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific frame 101 described in the above embodiments. For example, rings for connecting slings are symmetrically connected at both ends of the frame 101. The purpose of this arrangement is to facilitate the quick connection of the device with the sling rope through this arrangement.

[0020] Specifically, a lining plate 204 is fixedly connected to the other end of the frame 101 , and a push rod 205 is fixedly connected to the axis of the lining plate 204 .

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific liner 204 described in the above embodiments. For example, the liner 204 can be detachably fixed to the frame 101 by bolts. The purpose of this setting is to facilitate the adjustment of the connection position of the liner 204 and the frame 101 through this setting.

[0022] Specifically, a slide A206 is fixedly connected to the connecting rod 201 , and the slide A206 is threadedly connected to the screw rod 207 , and the screw rod 207 is rotatably connected to the frame 101 .

[0023] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific screw rod 207 described in the above embodiments. For example, the screw rod 207 can be a reciprocating screw rod. The purpose of this setting is that when the slider threaded on the reciprocating screw rod moves to one end, the movement direction of the slider can be quickly changed by continuing to control the reciprocating screw rod to rotate in the same direction.

[0024] Specifically, one end of the screw rod 207 is fixedly connected to the output shaft of the motor 208 , and the motor 208 is fixedly connected to the frame 101 .

[0025] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific motor 208 described in the above embodiments. For example, the motor 208 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the speed at which the sleeve 202 and the slide 203 are inserted into the utility pole through this setting.

[0026] Specifically, a push rod A209 is hinged on the slide 203, and the other end of the push rod A209 is hinged on the arc plate 303. The push rod A209 is rotatably connected to the push rod B301 through the short shaft on it.

[0027] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific top rod A209 and top rod B301 described in the above embodiments. For example, the top rod A209 and top rod B301 should be made of one-piece molded components with high hardness. The purpose of this setting is to prevent them from breaking under stress through this setting, and the hinges at both ends should be further hardened and clamped.

[0028] Specifically, one end of the push rod B301 is hinged to a slider 302 , the slider 302 is slidably connected to the arc plate 303 , and the other end of the push rod B301 is hinged to the sleeve 202 .

[0029] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific arc plate 303 described in the above embodiments. For example, a soft gasket is provided on the arc plate 303. The purpose of this setting is to facilitate providing a buffer when the arc plate 303 contacts the inner wall of the utility pole through this setting.

[0030] Specifically, a plurality of bottom rods 304 are symmetrically fixedly connected to the frame 101 , and a positioning hole 305 is provided on the slide 203 , and the positioning hole 305 is directly opposite to the top rod 205 .

[0031] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific bottom rod 304 described in the above embodiments. For example, a pulley with a self-locking effect is provided at the bottom of the bottom rod 304. The purpose of this setting is to facilitate the adjustment of the position of the device through this setting.

[0032] In the embodiment of the present invention, the user moves the device so that the hollow electric pole is close to the lining plate 204, and the motor 208 is started at this time, so that the screw rod 207 fixedly connected to the output shaft of the motor 208 starts to rotate, and the slide A206 threadedly connected to the screw rod 207 starts to slide along the connection between it and the frame 101. At this time, the connecting rod 201 fixedly connected to the slide A206 starts to slide synchronously, so that the connecting rod 201 pushes the sleeve 202 fixedly connected to it to start entering the interior of the electric pole, and pushes the slide 203 to start contacting the top rod 205. At this time, with the cooperation of the top rod 205, the positioning hole 305 starts to slide into the sleeve 202. At the same time, due to the damping rubber strip provided at the connection, the slide 203 can slide into the sleeve 202 at a uniform speed. At this time, the slide 203 starts to drive the top rod A209 hinged thereon to slide synchronously, so that the top rod A209 starts to push the arc plate 30 hinged thereto. When the sliding block 303 is in contact with the bottom of the groove of the sleeve 202, the multiple arc plates 303 begin to be in close contact with the inner wall of the groove, thereby fixing the pole with the multiple arc plates 303 to prevent shaking during hoisting and avoiding the pole from being broken by the two-end fixing method. At the same time, when the top rod 205 enters the positioning hole 305, the high-damping rubber ring provided on the positioning hole 305 can increase the damping of its sliding, so that when the sleeve 202 slides in the opposite direction after the hoisting is completed, the slide cylinder 203 can be limited by the top rod 205, thereby assisting the slide cylinder 203 to slide out and reset in the sleeve 202.

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. It can be categorized into two types: detachable connection and non-detachable connection.

[0035] (1) Removable connection: Components are fastened together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0036] (2) Non-detachable connections: These mainly refer to welding, riveting, and tenoning. Since parts must be forged, sawed, or oxygen-cut for disassembly during repair or replacement, they are generally not reusable. Furthermore, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration and polishing) during connection.

[0037] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinged connection referred to in this application means that the component can rotate along an axial constraint.

[0038] In some cases, the sliding connections and hinges referred to in this application may also be damped so that the components have the ability to maintain a desired position.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
