Description

Technical Field

[0001] This utility model relates to the field of crossarm installation technology, specifically a crossarm installation bracket. Background Technology

[0002] Crossarms are a crucial component of power poles, used to install insulators and fittings, support conductors and lightning protection wires, and maintain them at designated safe distances. Since crossarms are installed at the top of the pole, workers must climb the pole for installation. Maintaining safety and balance while climbing makes operating crossarms inconvenient, and multiple workers cannot easily cooperate at the top of the pole for installation. Therefore, it is essential to provide a crossarm installation device that can be operated by a single person, is simple and quick to install, and is safe. Utility Model Content

[0003] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a crossarm mounting bracket that can overcome the problems of inconvenient and inefficient crossarm installation and potential safety hazards.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A crossarm mounting bracket includes a pole locking part and at least one crossarm fixing part connected to the pole locking part. The pole locking part is detachably clamped onto the pole, and the crossarm fixing part presses the crossarm supported on the mounting bracket onto the pole. The pole locking part includes at least one mounting frame and at least one adjusting component. The mounting frame and the adjusting component are connected to form a closed-loop structure, which can clamp the pole. The adjusting component adjusts the circumference of the closed-loop structure by changing its own length within the closed-loop structure.

[0006] As a further improvement to the above technical solution:

[0007] The adjustment component includes a constraint member and a locking component, both of which are connected to the mounting frame. The constraint member is elongated and can be detached or locked from the locking component. The locking component changes the length of the adjustment component in the closed-loop structure by locking the constraint member at different positions.

[0008] The constraint component is a chain.

[0009] It is provided with two adjustment components and two mounting frames. The mounting frames are arc-shaped rigid components. The two adjustment components and two mounting frames are arranged alternately. Each mounting frame is connected to two adjustment components at both ends, and each adjustment component is connected to two mounting frames at both ends.

[0010] The two adjustment components may be the same or different.

[0011] The locking assembly includes a screw, an adjusting handwheel, and a limiting member. One end of the limiting member is connected to the mounting frame, and the other end is connected to the screw. The limiting member is fixedly installed on the mounting frame, and the screw can pass through the limiting member and be screwed and locked to the adjusting handwheel.

[0012] The locking component is a latch, which is installed on the mounting frame. The locking component and the constraint are fastened together to achieve locking.

[0013] The crossarm fixing part includes a mounting bracket and an elastic component. The mounting bracket is mounted on the mounting frame. When the mounting bracket is mounted on the pole, there is a gap between the mounting bracket and the pole. This gap is used to insert the crossarm. The elastic component is preset to a compressed state. The elastic component applies pressure to the mounting bracket to press the crossarm between the mounting bracket and the pole.

[0014] The mounting bracket includes a horizontal plate and a vertical plate connected to each other in an L-shape. One end of the vertical plate is connected to the mounting frame, and the other end faces upward and is connected to one end of the horizontal plate. The other end of the horizontal plate extends outward away from the center of the closed-loop structure. The elastic component includes a spring and a pin. The spring is installed below the horizontal plate in a compressed state, and the pin is fixed below the horizontal plate and passes through the spring.

[0015] The crossarm fixing part also includes a crossarm fixing assembly, which includes a fixing device and a fixing device locking member. The fixing device is located above the horizontal plate, and the fixing device locking member can press the fixing device onto the horizontal plate. The crossarm includes a vertical part and a horizontal part, which are connected to form an L-shape. After installation, the vertical part is located between the vertical plate and the pole, and the horizontal part is located above the horizontal plate. The fixing device presses the horizontal part between the fixing device and the horizontal plate.

[0016] The beneficial effects of this utility model are:

[0017] (1) It can be operated by a single person, is easy and efficient to install, simple to operate, saves time and effort, and greatly reduces safety risks by reducing installation time: the mounting bracket can be firmly fixed on the pole by fastening the restraint and the lock and rotating the adjustment handwheel, while pressing the crossarm on the pole.

[0018] (2) Rotating the adjustment handwheel can gradually tighten the pole locking part and gradually press the crossarm onto the pole. In this way, the adjustment handwheel can be rotated until the crossarm is not clamped tightly enough so that the crossarm will not fall off. At the same time, the horizontal position of the crossarm can be adjusted.

[0019] (3) The mounting bracket has a simple structure and is applicable to a wide range of scenarios. Attached Figure Description

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0024] A type of crossarm mounting bracket, such as Figure 1 and Figure 2 As shown, the device includes a pole locking part and at least one crossarm fixing part 2 connected to the pole locking part. The pole locking part is detachably secured to the pole, and the crossarm fixing part 2 presses the crossarm supported on the mounting bracket onto the pole.

[0025] The pole locking part includes at least one mounting frame 11 and at least one adjusting component 12. The mounting frame 11 is an arc-shaped rigid component, and the adjusting components 12 may be the same or different. The mounting frame 11 and the adjusting component 12 are connected to form a closed-loop structure, which can grip the pole. The adjusting component 12 adjusts the circumference of the closed-loop structure by changing its own length in the closed-loop structure, thereby enabling the pole locking part to grip or release the pole.

[0026] In this embodiment, two adjusting components 12, two mounting frames 11, and two crossarm fixing parts 2 are provided. The two adjusting components 12 and the two mounting frames 11 are arranged alternately. Each mounting frame 11 has two adjusting components 12 connected to its two ends, and each adjusting component 12 has two mounting frames 11 connected to its two ends. The two crossarm fixing parts 2 are respectively installed on the two mounting frames 11, and the two crossarm fixing parts 2 are arranged symmetrically. Each crossarm fixing part 2 can install one crossarm.

[0027] In this embodiment, the mounting frame 11 is made of high-strength aluminum alloy.

[0028] The adjusting component 12 includes a constraint member 121 and a locking component 122, both of which are connected to the mounting frame 11. The constraint member 121 is elongated, and the constraint member 121 and the locking component 122 can be detached or locked together. The locking component 122 changes the length of the adjusting component 12 in the closed-loop structure by locking the constraint member 121 at different positions. Preferably, the constraint member 121 is a chain.

[0029] In this embodiment, the two adjustment components 12 are different.

[0030] In this embodiment, the locking component 122 of the first adjusting component 12 includes a screw 1221, an adjusting handwheel 1222, and a limiting member 1223. One end of the limiting member 121 is connected to one end of a mounting frame 11, and the other end of the limiting member 121 is connected to the screw 1221. The limiting member 1223 is a tubular structure and is fixedly installed at one end of another mounting frame 11. The screw 1221 can pass through the limiting member 1223 and then through the adjusting handwheel 1222 with internal threads, so that the screw 1221 and the adjusting handwheel 1222 are screwed and locked. One end of the adjusting handwheel 1222 is inserted into the limiting member 1223, and the outer diameter of the other end is larger than that of the limiting member 1223, so that the adjusting handwheel 1222 is blocked by the limiting member 1223 and will not be dragged away by the screw 1221. The adjusting handwheel 1222 can also be mounted on the limiting member 1223 in a rotatable manner relative to the limiting member 1223. Thus, the adjusting handwheel 1222 and the screw 1221 effectively form a lead screw mechanism. When the adjusting handwheel 1222 is rotated, the screw 1221 moves along the length direction of the limiting member 1223, causing the constraint member 121 to move synchronously, thereby changing the length of the constraint member 121 in the closed-loop structure. After stopping the operation of the adjusting handwheel 1222, the adjusting handwheel 1222 and the screw 1221 can self-lock in their current positions. Preferably, the corresponding constraint member 121 is a plate chain.

[0031] In this embodiment, the locking component 122 of the second adjusting component 12 is a buckle. The buckle is installed at one end of a mounting frame 11, and one end of a constraint member 121 is connected to one end of another mounting frame 11. The constraint member 121 can be fastened to the buckle at different positions along its length to achieve locking. The chain is fastened to the buckle using existing technology. For example, the buckle is a bolt, and a loop of the chain (constraint member 121) is fitted onto the bolt from top to bottom, and then a nut is installed.

[0032] In this embodiment, the constraint 121 of the second adjustment component 12 is made of manganese steel.

[0033] The crossarm fixing part 2 includes a mounting bracket 21, an elastic component 22, and a crossarm fixing component 23.

[0034] Mounting bracket 21 includes a horizontal plate 211 and a vertical plate 212 connected to each other. The horizontal plate 211 and the vertical plate 212 are connected in an L-shape. One end of the vertical plate 212 is connected to the mounting frame 11, and the other end is upward and connected to one end of the horizontal plate 211. The other end of the horizontal plate 211 extends outward in a direction away from the center of the closed loop structure.

[0035] In this embodiment, the mounting bracket 21 is made of aluminum alloy.

[0036] The elastic component 22 includes a spring 221 and a pin 222. The spring 221 is installed in a compressed state below the horizontal plate 211, and the pin 222 is located below the horizontal plate 211, passing through the spring 221. Specifically, two limiting plates can be fixed to the bottom surface of the horizontal plate 211 by welding or other means. The spring 221 is located between these two limiting plates and is pressed by them. After passing through the spring 221 and the two limiting plates, the pin 222 can be locked with a nut or directly fixed to the vertical plate 212 by welding or other means. Preferably, the length direction of the pin 222 is perpendicular to the vertical plate 212. Furthermore, the limiting plate near the end of the vertical plate 212 contacts the vertical plate 212 to facilitate the transmission of the elastic force of the spring 221.

[0037] The crossarm fixing assembly 23 includes a retainer 231 and a retainer locking member 232. The retainer 231 is located above the cross plate 211, and the retainer locking member 232 can press the retainer 231 onto the cross plate 211. In this embodiment, the retainer locking member 232 is a bolt, to which a nut is screwed. The bolt is then passed from top to bottom through the retainer 231 and the cross plate 211, and then the nut is screwed on. In this way, both the retainer 231 and the retainer locking member 232 can be removed from the cross plate 211, and the retainer 231 can be pressed onto the cross plate 211 by rotating the nut above the cross plate 211.

[0038] In this embodiment, the fixture 231 is made of polyphenolic resin.

[0039] The crossarm includes a vertical part and a horizontal part, which are connected in an L-shape. After installation, the vertical part is located between the vertical plate 212 and the pole, and the horizontal part is located above the horizontal plate 211. One end of the horizontal part can be inserted between one end of the fixing device 231 and the horizontal plate 211, and the fixing device 231 presses the horizontal part tightly between the fixing device 231 and the horizontal plate 211.

[0040] Based on the above structure, the working principle and process of this utility model are as follows: The latch (locking component 122) and constraint member 121 of the second adjusting component 12 are released, causing them to detach. The worker carries the mounting bracket up to the top of the pole and locks the pole locking part approximately 150 mm below the position of the crossarm to be installed. Specifically, after the two mounting frames 11 encircle the pole, the constraint member 121 of the second adjusting component 12 is fastened onto the latch (locking component 122), selecting a position where the constraint member 121 is engaged to prevent the mounting bracket from falling down. Then, the crossarm is placed between the vertical plate 212 and the pole, and its horizontal position is adjusted. Next, the adjusting handwheel 1222 is rotated to reduce the circumference of the closed-loop structure, which is equivalent to tightening the constraint member 121 of the first adjusting component 12, causing the pole locking part to stably and firmly grip the pole. Simultaneously, the vertical plate 212 presses the crossarm against the spring 221. Rotate the nut on the locking part 232 of the fixing device to press one end of the fixing device 231 against the crossarm plate. In this way, the crossarm is stably installed on the pole. If the crossarm needs to be removed, rotate the adjusting handwheel 1222 to loosen the pole locking part, release the pressure on the crossarm, and then the crossarm can be removed.

[0041] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
