Description

Technical Field

[0001] This utility model relates to the field of communication box maintenance technology, specifically a communication box maintenance ladder. Background Technology

[0002] Communication engineering mainly studies the generation, transmission, exchange, and processing of signals, as well as the theoretical and engineering applications in computer communication, digital communication, satellite communication, fiber optic communication, cellular communication, personal communication, stratospheric communication, multimedia technology, information superhighway, and digital program-controlled switching. With the increasingly widespread application of communication technology, communication boxes have long been ubiquitous in various communities. In practical applications, existing communication boxes are typically installed on external circular poles such as utility poles or uprights. Wall-mounted boxes are convenient for climbing using ladders for support. However, for maintenance applications of communication boxes installed on external circular poles, the following shortcomings exist: Since external poles are cylindrical, they cannot provide stable support for the ladder, lacking a mechanism for securing the ladder. This poses a risk of the ladder slipping, separating, and tipping over during maintenance, resulting in poor safety. Therefore, this application proposes a communication box maintenance ladder to address these problems. Utility Model Content

This facilitates safe climbing and maintenance work and improves safety. 2. Through the combination of the rotating support and locking components and the U-shaped frame, the U-shaped frame can be folded when not in use and turned out and locked when in use, reducing the space occupied when not in use; 3. The folding clamping support anti-detachment mechanism can be disassembled and assembled by using the set clamp sleeve and the first knob-type bolt.

[0012] This utility model incorporates a series of structures that facilitate the fixing of the upper part of the ladder body to the circular rod carrier by clamping it. This allows for stable and secure fixation of the upper part of the ladder body to the circular rod carrier, preventing the ladder body from easily slipping off and tipping over on the outside of the circular rod carrier, thus improving safety. The U-shaped frame can be easily folded when not in use and unscrewed and locked when in use, reducing space occupation when not in use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, the communication box maintenance ladder proposed in this embodiment includes a ladder body, which includes two side supports 1 and a plurality of climbing steps 101 fixedly connected between the two side supports 1. The same folding clamping support anti-detachment mechanism is installed on the top of the outer side of the two side supports 1. The foldable clamping support anti-detachment mechanism includes: The ferrule 2 consists of two sets, which are movable and fitted on the top of the outer side of the corresponding side bracket 1. The top of the two opposing sides of the side bracket 1 is provided with threaded grooves, and the first knob bolt 201 is threadedly screwed into the threaded grooves. The ferrule 2 is threadedly fitted onto the corresponding knob bolt 201. The rotary locking assembly consists of two sets, which are respectively fixedly connected to the right side of the corresponding ferrule 2; The U-shaped frame 4 is fixedly connected between two rotary support and locking components. A rectangular groove 401 is provided on its rear inner wall. The rotary support and locking components are used to rotate and lock the U-shaped frame 4. The U-shaped frame 4 is adjustable, which makes it convenient to rotate and fold it downward to the right side of the side support 1 after use, and also allows it to be rotated to be used horizontally when in use. The threaded horizontal guide drive assembly is installed in the rectangular slot 401, and a V-shaped clamping block 402 located inside the U-shaped frame 4 is fixedly connected to its front side. The threaded horizontal guide drive assembly is used to drive the V-shaped clamping block 402 to move left and right. When the communication box is installed on an external round pole carrier such as a utility pole or upright, the U-shaped frame 4 is clamped forward on the outside of the round pole carrier, and the V-shaped clamping block 402 is moved to the left to clamp the round pole carrier, thereby fixing the U-shaped frame 4 and fixing the upper part of the ladder body. This avoids the phenomenon that the conventional ladder body is difficult to stably lean against the outside of the round pole carrier. In this embodiment, an anti-slip rubber block is bonded and fixed on the inner left side of the U-shaped frame 4, and a V-shaped anti-slip rubber pad is bonded and fixed on the left side of the V-shaped clamp 402. The V-shaped anti-slip rubber pad improves the anti-slip performance when clamped. A first threaded hole is opened on the opposing side of the two clamping sleeves 2, and the first threaded hole is threadedly connected to the corresponding first knob bolt 201.

[0017] Furthermore, such as Figure 1 , 2As shown in Figures 3 and 4, the rotary locking assembly includes a support 3, a rotating shaft 301, a rotating seat 302, and a second knob bolt 303. The two supports 3 are welded and fixed to the right side of the corresponding sleeve 2, respectively. The front left side and the rear left side of the U-shaped frame 4 are welded and fixed to the corresponding rotating shaft 301, respectively. The support 3 is rotatably sleeved on the corresponding rotating shaft 301. The opposing ends of the two rotating shafts 301 are welded and fixed to the corresponding rotating seat 302, respectively. Threaded grooves 304 are provided on the bottom of the opposing side and the right side of the opposing side of the two supports 3. The two second knob bolts 303 are threaded into the corresponding right-side threaded grooves 304, respectively. The rear side of the rotating seat 302 is provided with a threaded through hole that is threadedly connected to the corresponding second knob bolt 303. In this embodiment, a first circular hole is provided on the front side of the support 3, and two first bearings are fixedly sleeved in the first circular hole. The inner ring of the first bearing is fixedly sleeved with the outer side of the corresponding rotating shaft 301, so as to achieve the effect of rotating the rotating shaft 301. In this embodiment, the support 3, rotating shaft 301, rotating seat 302, and second knob bolt 303 cooperate to rotate the corresponding rotating shaft 301, thereby achieving the rotational installation of the U-shaped frame 4 using the rotating shaft 301. The second knob bolt 303 locks the rotating seat 302, further securing the U-shaped frame 4 through the rotating shaft 301. Rotating the second knob bolt 303 in the opposite direction separates it from the corresponding right-side threaded groove 304, releasing the lock on the rotating seat 302. The U-shaped frame 4 can then be rotated downwards to fold to the right of the two side supports 1, reducing its unused position. The right side occupies space. The U-shaped frame 4 drives the two second knob bolts 303 to rotate downwards via two pivots 301 and two rotating seats 302, aligning them with the threaded grooves 304 below. The second knob bolts 303 can then be rotated clockwise to screw into the corresponding threaded grooves 304 below for locking. When it needs to be rotated to the right to be horizontal for subsequent use, it is unlocked again. The U-shaped frame 4 is then rotated to the right to be horizontal, and the second knob bolts 303 are used to lock it. This achieves the effect of conveniently folding the U-shaped frame 4 when not in use and rotating it out and locking it when in use.

[0018] Furthermore, such as Figure 3 and 4As shown, the threaded transverse guide drive assembly includes a fixed base 403, four transverse guide rods 404, a screw 405, a movable base 406, and a drive motor 407. The fixed base 403 is welded and fixed to the rear inner wall of the rectangular groove 401. The four transverse guide rods 404 are rectangularly fixedly connected between the right side of the fixed base 403 and the right inner wall of the rectangular groove 401. The movable base 406 is slidably sleeved on the four transverse guide rods 404. The front side of the movable base 406 is welded and fixed to the right side of the V-shaped clamp 402. The screw 405 is rotatably embedded between the right side of the fixed base 403 and the right inner wall of the rectangular groove 401. The movable base 406 is threadedly sleeved on the screw 405. The drive motor 407 is fixedly installed on the left inner wall of the rectangular groove 401. The output shaft of the drive motor 407 is fixedly connected to the left end of the screw 405. In this embodiment, the right side of the movable seat 406 is provided with a second threaded hole that is threadedly connected to the screw 405. The threaded connection between the screw 405 and the second threaded hole facilitates the lateral displacement of the movable seat 406 when the screw 405 rotates. The right inner wall of the rectangular groove 401 is provided with an insert groove, and the right side of the fixed seat 403 is provided with a second circular hole. A second bearing is fixedly connected to both the second circular hole and the insert groove. The inner ring of the second bearing is fixedly connected to the outer side of the screw 405, which facilitates the rotational installation of the screw 405. The right side of the movable seat 406 is provided with four transverse guide holes that slide and fit with the outer side of the corresponding transverse guide rod 404, which serve as lateral sliding guides for the movable seat 406. In this implementation scheme, the fixed base 403, four horizontal guide rods 404, screw 405, movable base 406, and drive motor 407 work together. The drive motor 407 drives the screw 405 to rotate, and the rotation of the screw 405 drives the movable base 406 to slide to the left or move back to the right on the four horizontal guide rods 404. The movable base 406 drives the V-shaped clamp 402 to move to the left or move back to the right. When the communication box is installed on an external round pole or upright, the U-shaped frame 4 is clamped forward onto the outside of the round pole, and the V-shaped clamp 402 is moved to the left to clamp the round pole, thus fixing the U-shaped frame 4 and fixing the upper part of the ladder body. This avoids the phenomenon that the main body of a conventional ladder is difficult to stably lean against the outside of the round pole, and also avoids the phenomenon that the main body of the ladder is prone to lateral slippage, separation, and tipping on the outside of the round pole, thus improving the safety of climbing on the outside of the round pole.

[0019] Furthermore, a wireless remote control switch is fixed and electrically connected to the front of the drive motor 407. An external remote control is matched with the wireless remote control. A lithium battery is fixedly connected to the U-shaped frame 4. The lithium battery is electrically connected to the drive motor 407 and the wireless remote control switch through wires.

[0020] It should be noted that the ladder body can be any type of ladder available on the market, such as telescopic ladders or assembled ladders, as long as the upper part of the ladder side bracket protrudes and is compatible with the card sleeve 2; the wireless remote control switch preferably uses the CE31-BxxR series remote control switch, which has the advantage of high remote control sensitivity within a certain distance, meeting the requirements for non-long-distance remote control; the lithium battery preferably uses the Lunqu Technology P760S model lithium battery with integrated charge and discharge protection function, which can provide safe power to the drive motor 407; in addition, the technical solution of using the lithium battery to provide power through wires and to cooperate with the wireless remote control switch to complete the opening and closing control is a well-known and mature technology in this field, and its specific working principle and conventional wire connection method will not be described in detail here; It should be further noted that the ferrule 2, knob bolt 201, U-shaped bracket 4, V-shaped clamp 402, support 3, rotating shaft 301, rotating seat 302, second knob bolt 303, fixed seat 403, horizontal guide rod 404, screw 405 and moving seat 406 are all preferably made of stainless steel. The screw 405 has a high wear-resistant load-bearing specification with a thread gap of 1-2mm on the outer side. The stainless steel material has the advantages of high hardness, high wear resistance, high corrosion resistance and good maintenance-free effect, which ensures the stability of long-term connection and drive support.

[0021] The usage method of this embodiment is as follows: When using the communication box maintenance ladder, for maintenance of communication boxes on external round pole carriers such as utility poles and uprights, move the main body of the ladder so that it drives the U-shaped frame 4 to fit over the outside of the round pole carrier from back to front, so that the round pole carrier contacts the anti-slip rubber block on the left. Then, the personnel use the external remote control to operate the wireless remote control switch to control the drive motor 407 to start forward, so that it drives the screw 405 to rotate. The rotation of the screw 405 drives the moving seat 406 to slide to the left on the four horizontal guide rods 404. The movable seat 406 drives the V-shaped clamp 402 to move to the left, and the V-shaped clamp 402 drives the V-shaped anti-slip pad to clamp the circular rod carrier to the left, thereby fixing the U-shaped frame 4 and fixing the upper part of the ladder body. This makes it easy to stably fix the upper part of the ladder body against the circular rod carrier, avoiding the phenomenon that the ladder body is easy to slip off and fall over on the outside of the circular rod carrier. This improves the safety of climbing on the outside of the circular rod carrier, facilitates safe climbing and maintenance work, and improves the safety of use. After use, reverse start drive motor 407 moves in the opposite direction to forward start drive motor 407. At this time, moving seat 406 moves back to the right, driving V-shaped clamp 402 to move to the right, releasing the clamping state, and the ladder body can be removed. Reverse turn the two second knob bolts 303 to separate them from the corresponding right-side threaded grooves 304, releasing the lock on rotating seat 302. Then, rotate U-shaped frame 4 downward to fold it to the right side of the two side supports 1, reducing the space occupied on the right side when not in use. U-shaped frame 4 drives the two second knob bolts 303 to rotate downward through two rotating shafts 301 and two rotating seats 302, aligning them with the lower threaded grooves 304. Then, the second knob bolts can be rotated forward. The knob bolt 303 is screwed into the corresponding threaded groove 304 below for locking. When it needs to be turned to the right to be horizontal for subsequent use, it is unlocked again. Then the U-shaped frame 4 is turned to the right to be horizontal, and then locked with the second knob bolt 303. This achieves the effect of folding the U-shaped frame 4 when not in use and turning it out and locking it when in use, reducing the space occupied when not in use. In addition, when the first knob bolt 201 is turned in the opposite direction to separate it from the corresponding threaded groove, the locking of the sleeve 2 is released, and the sleeve 2 can also be separated from the side bracket 1 upwards. This achieves the effect of convenient disassembly and assembly of the folding clamping support anti-detachment mechanism. Through its disassembly and assembly method, it can be reused when the main body of the ladder is damaged in the future, improving its practicality.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
