Abstract

This invention discloses an adjustable cable hoisting frame for stable clamping, comprising a frame and a limiting rod. The frame is connected to the outer wall of an upright plate, and a lifting and moving mechanism is provided at the bottom of the frame. Driven by a motor, the rotating drum drives the first lead screw to rotate via a belt drive structure, causing the slider on the first lead screw to move inward in the same direction. During the slider's movement, it pushes the moving rod along the sleeve inward via an extension plate, thereby pushing the limiting seat to move relative to the inside of cable reels of different sizes. Simultaneously, the insert plate on one side of the limiting seat, during its inward movement, penetrates and inserts into the inside of another set of opposing limiting seats, squeezing the sliding seat and causing the limiting rod to move and contact the side wall of the cable reel. This fixes cable reels of different sizes on the outside of the limiting seat. Furthermore, because the limiting seat and the moving rod are rotatably connected, the cable reel meets the requirements for rotating and unloading while preventing it from shifting.

[0015] Preferably, the lifting and moving mechanism includes a lifting plate, a column, universal self-locking wheels, a through hole, support feet, a hydraulic cylinder, and a base.

The column is inserted through the through hole, which is located on the base.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the adjustable cable hoisting frame facilitates stable clamping,

[0017] (1) The present invention effectively solves the problem that most existing cable hoisting frames do not have a limiting structure in order to ensure the normal rotation of the cable reel, which easily leads to the cable reel moving and deviating when releasing the cable, thus affecting the normal progress of cable laying. Under the drive of the motor, the rotating drum will drive the fixed block, i.e. the first lead screw and the second lead screw, to rotate synchronously through the belt transmission structure, so that the slider on the first lead screw moves inward in the same direction. During the movement of the slider, the moving rod will be pushed along the sleeve inward through the extension plate, thereby pushing the limiting seat to move relatively through the interior of cable reels of different sizes. At the same time, the limiting seat on one side During the inward movement of the insert plate, it will penetrate and insert into the internal squeezing sliding seat of another set of opposing limiting seats, causing it to drive the limiting rod to move and contact the side wall of the cable reel. This allows cable reels of different sizes to be fixed on the outside of the limiting seat. At the same time, since the limiting seat and the moving rod are rotatably connected, the cable reel meets the requirements for rotating cable laying and will not deviate. In addition, as the slider on the first lead screw moves inward in the same direction, the slider on the second lead screw will move outward synchronously, allowing the empty cable reel clamped on its inner side to be removed for replacement. Similarly, the motor can be reversed to replace the cable reel that has been used up on the inner side of the first lead screw, thereby improving the continuity of the laying work and increasing the laying efficiency.

[0018] (2) The present invention can effectively solve the problem that cable reels are prone to falling off and injuring people due to equipment failure during the use of existing cable hoisting frames by using the combination of rotating rod, warning mechanism and warning light. When the motor drives the rotating drum to rotate and moves and clamps the cable reels on the first screw and the second screw, the rotating rod will rotate to wind up the corresponding rope. During the winding process, the rope will drive the installation plate to move and squeeze the control switch. When the control switch is squeezed, it will control the warning light to light up. Conversely, when the device fails, the warning light is off. That is, when the workers are laying power, they can check the working status of the warning light to judge whether the device is clamping normally, thereby improving the safety of the device, avoiding accidental injury from falling cable reels due to device failure, and thus optimizing the device structure.

[0019] (3) The present invention can effectively solve the problem that most existing cable hoisting frames are structurally fixed and are not convenient to move and adjust according to the actual construction situation by lifting and moving. The universal self-locking wheel can facilitate the workers to move the position of the device when the device is not in use, thereby improving the portability of the device. When the device is working, the workers can control the hydraulic cylinder to push the lifting plate to move up. During the process of the lifting plate moving up, the universal self-locking wheel will move synchronously through the column to move it away from the ground, that is, the support foot is used to support the device, thereby avoiding the device from moving accidentally during operation and improving the stability of the device. At the same time, it avoids the universal self-locking wheel from being damaged due to long-term pressure. During the process of the lifting plate moving up, the clamping height of the device will be adjusted, thereby improving the flexibility of the device structure, enabling the device to meet different fixing requirements, and thereby expanding the application range of the device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 This invention provides a technical solution: an adjustable cable hoisting frame that facilitates stable clamping. Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the frame 1 is connected to the outer wall of the upright plate 2, and the bottom of the frame 1 is provided with the upright plate 2 symmetrically arranged on the support plate 3. At the same time, the bottom of the frame 1 is provided with a lifting and moving mechanism 22. The inner side of the upright plate 2 is symmetrically provided with a first lead screw 4, and a second lead screw 6 is provided on one side of the first lead screw 4. The first lead screws 4 are connected by a fixing block 5, and the fixing block 5 is connected to the rotating drum 16 through a belt drive structure. One end of the rotating drum 16 is connected to the output end of the motor 17, and the other end of the rotating drum 16 is connected to the motor 17 through the rotating drum 16. The alarm mechanism 18 is connected, and the alarm mechanism 18 is provided with two sets. The first lead screw 4 and the second lead screw 6 are both provided with sliders 7, and the sliders 7 are connected to the moving rod 9 through the extension plate 8. The moving rod 9 is located inside the sleeve 10. One end of the moving rod 9 is connected to the limit seat 11, and the limit seat 11 is provided with a sliding seat 14. The outer side of the sliding seat 14 is provided with a plate 15. The limit rod 13 is connected to the sliding seat 14, and the two sides of the limit rod 13 are symmetrically provided with return springs 12.

[0029] In a further embodiment, the threads on the first lead screw 4 and the second lead screw 6 are opposite, and the second lead screw 6 are connected by a fixing block 5.

[0030] In a further embodiment, the sliders 7 are symmetrically arranged on the first lead screw 4 and the second lead screw 6, and the sliders 7 move relative to each other in pairs, while the sliders 7 are slidably connected to the inner side of the support plate 3.

[0031] In a further embodiment, the extension plate 8 and the moving rod 9 are both slidably connected inside the sleeve 10, and the moving rod 9 is rotatably connected to the limiting seat 11.

[0032] In a further embodiment, the side of the sliding seat 14 adjacent to the insert plate 15 is inclined, and the sliding seat 14 is slidably connected inside the limiting seat 11, while the insert plate 15 is slidably connected to the limiting seat 11.

[0033] In a further embodiment, the rotating drum 16 is rotatably connected to the fixed frame 21, and both the fixed frame 21 and the motor 17 are mounted on the rear wall of the support plate 3.

[0034] In a further embodiment, the lifting and moving mechanism 22 includes a lifting plate 2201, a column 2202, a universal self-locking wheel 2203, a through hole 2204, a support foot 2205, a hydraulic cylinder 2206, and a base 2207. The lifting plate 2201 is connected to the top of the base 2207 via the hydraulic cylinder 2206. The lifting plate 2201 is connected to the universal self-locking wheel 2203 via the column 2202. The universal self-locking wheel 2203 is symmetrically arranged inside the support foot 2205, and the support foot 2205 is symmetrically arranged at the bottom of the base 2207. The column 2202 is inserted through the through hole 2204, and the through hole 2204 is formed on the base 2207.

[0035] Specifically, in the actual working process, the device is first moved to the designated position using the universal self-locking wheel 2203. Then, the power supply is connected to start the device, and the hydraulic cylinder 2206 is controlled to push the lifting plate 2201 through the column 2202 to pull the universal self-locking wheel 2203 up away from the ground, so that the support foot 2205 supports the device. At the same time, the operator can adjust the cable reel laying height by controlling the extension length of the hydraulic cylinder 2206.

[0036] Next, motor 17 drives drum 16 to rotate. During the rotation of drum 16, the belt drive structure drives two sets of fixed blocks 5 to rotate synchronously. The fixed blocks 5 drive the corresponding first lead screw 4 and second lead screw 6 to rotate, thereby causing the slider 7 on the first lead screw 4 to move inward in the same direction. During the movement of slider 7, it pushes the moving rod 9 along the sleeve 10 inward through the extension plate 8, thereby pushing the limiting seat 11 to move relative to each other and penetrate the inside of the cable reel. At the same time, the insert plate 15 on one side of the limiting seat 11 will penetrate and insert into the inside of the other set of opposite limiting seats 11 during the inward movement, squeezing the sliding seat 14 and its inner return spring 12, causing it to push the corresponding limiting rod 1. 3. The relative movement limits the side wall of the cable reel, thereby fixing cable reels of different sizes to the outside of the limiting seat 11 to prevent them from shifting. At the same time, the slider 7 on the second lead screw 6 will move outward synchronously, causing the insert plate 15 to be pulled out from the inside of the limiting seat 11. At this time, the return spring 12 will stop being compressed and will pull the limiting rod 13 inward through the sliding seat 14 to retract into the inside of the sleeve 10. Thus, the empty cable reel fixed to the outside of the limiting seat 11 can be removed and replaced with a new one. On the other hand, during the rotation of the rotating drum 16, it will drive the rotating rod 19 to rotate and trigger the warning mechanism 18 on one side, causing it to control the warning light 23 corresponding to the first lead screw 4 to light up, indicating that the device is working normally. Example

[0037] This embodiment is a further description of the above embodiments. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0038] like Figure 1 and Figure 3 As shown, in a further embodiment, the warning mechanism 18 includes a rope 1801, a telescopic spring 1802, a mounting plate 1803, and a control switch 1804. One end of the rope 1801 is connected to the mounting plate 1803, and the mounting plate 1803 is connected to the fixing plate 20 through the telescopic spring 1802. The control switch 1804 is mounted on the fixing plate 20, and the fixing plate 20 is connected to the fixing frame 21.

[0039] In a further embodiment, the other end of the rope 1801 is wound onto the rotating rod 19, and the rotating rod 19 is connected to the rotating drum 16.

[0040] In a further embodiment, the control switch 1804 is electrically connected to the warning light 23, and the warning light 23 is mounted on the outer wall of the sleeve 10.

[0041] Specifically, the rope 1801 on one side will be wound onto the rotating rod 19 as the rod rotates. During the winding process, the rotating rod 19 will pull the corresponding mounting plate 1803 to press and trigger the control switch 1804, causing the corresponding warning light 23 to light up. The rope 1801 wound onto the rotating rod 19 on the other side will be released simultaneously. Then, the telescopic spring 1802 will push the mounting plate 1803 to reset and end the pressing on the control switch 1804, causing the corresponding warning light 23 to turn off. At this time, the cable reel on the corresponding second lead screw 6 is in the replacement state.

[0042] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
