Description

Technical Field

[0001] This utility model relates to the field of cable construction technology, specifically a cable lifting device. Background Technology

[0002] Cable lifting devices are indispensable key equipment in the power, telecommunications, and construction industries for cable laying, installation, or maintenance. Their function is to achieve safe and efficient lifting and movement of cables through mechanical structures. Cable lifting devices are specialized machines or equipment used during cable laying, installation, maintenance, or replacement to achieve the safe lifting, handling, positioning, or fixing of cables. Their core function is to use mechanical force (manual, electric, or hydraulic) to lift cables from the ground, cable reels, or transport vehicles and precisely move them to the target location, avoiding the safety hazards and efficiency problems associated with direct manual handling.

[0003] In existing technology, such as the lifting device for power plant cables disclosed in publication number CN213231177U, a fixed block is included. A lifting lug is fixedly connected to the top surface of the fixed block. The fixed block has several limiting grooves through which wires can pass. A through groove communicating with the limiting groove is formed on the fixed block. A pressure plate is installed within the through groove. A bracket is provided at the front of the fixed block, and a clamping bolt that moves toward the through groove is threaded onto the bracket. The inner end of the clamping bolt is rotatably connected to the pressure plate. A downward-opening groove is formed at the lower end of the fixed block, and a winding roller that can be stopped from rotating is rotatably connected within the groove. Steel wire is wound on the winding roller. The two winding rollers are parallel, and the wire exit ends are respectively provided with mutually cooperating locking rods and slots. This device satisfies two needs with one unit, thus saving the time and effort required to change equipment when lifting cables or cable reels, while improving work efficiency.

[0004] Existing lifting devices can save time and effort spent on changing equipment when lifting cables or cable reels, and improve work efficiency. However, most lifting devices are inconvenient to move during use, and it is inconvenient to move the cable to the target location after lifting it, which makes them less practical. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that most of the existing lifting devices are inconvenient to move during use, and that it is inconvenient to move the cable to the target location after lifting it, they are not very practical.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cable lifting device includes a mounting frame with support frames fixed at both ends. The lower surface of the support frame is provided with a limiting mechanism for limiting the device, the outer surface of the mounting frame is provided with an adjustment mechanism for adjustment, and the interior of the mounting frame is provided with a driving mechanism for driving.

[0009] The limiting mechanism includes two fixing plates, which are respectively fixed to the lower surfaces of two support frames. Each of the two fixing plates is threaded with two adjusting screws. The lower surfaces of the two adjusting screws are fixed with support seats, and the upper surfaces of the two adjusting screws are fixed with hand-tightening parts.

[0010] As a further embodiment of this utility model: the adjustment mechanism includes a movable component, which is slidably mounted on the outer surface of the mounting frame, and a mounting plate is fixed on the lower surface of the movable component.

[0011] As a further embodiment of this utility model: a protective shell is fixed to the lower surface of the mounting plate, and a steel rope roller is installed inside the protective shell.

[0012] As a further embodiment of this utility model: a steel rope body is externally connected to the steel rope roller, and a fixed hook is fixed to the lower end of the steel rope body.

[0013] As a further improvement of this utility model: both ends of the steel rope roller are fitted with fixed bearings, and the outer surface of the fixed bearings is fixed with a limiting plate that is fixedly connected to the protective shell.

[0014] As a further improvement of this utility model: the drive mechanism includes a walking motor, which is fixed to the inner wall of the mounting frame by bolts.

[0015] As a further improvement of this utility model: the power output shaft of the walking motor is fixed with a drive gear, and a fixed rack meshes with one side of the drive gear.

[0016] As a further improvement of this utility model: two guide strips are symmetrically fixed to the outer wall of the mounting bracket, and the outer sides of the two guide strips are slidably connected to a limiting groove opened in the movable part.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model allows the device to be easily moved to a suitable position. By turning the adjustment screw on the fixed plate and turning the hand screw, the support base can be driven to move vertically, so that the support base contacts the ground, thereby supporting and limiting the device and effectively reducing the possibility of accidental movement of the device.

[0019] 2. This utility model uses a mounting bracket on a support frame. The walking motor inside the movable part can drive the drive gear to rotate, so that the drive gear meshes with the fixed rack. The walking motor itself will drive the movable part to move horizontally on the mounting bracket, thereby facilitating the adjustment of the device.

[0020] 3. The present invention, through the setting of guide strips, can play a guiding and limiting role with the cooperation of limiting grooves, so as to ensure the stability of the moving parts during movement.

[0021] 4. This utility model uses a protective shell on the mounting plate, and an external motor drives the steel rope reel to run, thereby causing the steel rope to retract or extend. By connecting the fixed hook to the cable to be lifted, the cable can be lifted. Attached Figure Description

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Please see Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a cable lifting device, including a mounting frame 1. Both ends of the mounting frame 1 are fixed with support frames 2. The lower surface of the support frame 2 is provided with a limiting mechanism for limiting the device. The outer surface of the mounting frame 1 is provided with an adjustment mechanism for adjustment. The interior of the mounting frame 1 is provided with a driving mechanism for driving.

[0032] The limiting mechanism includes a fixed plate 3, and there are two fixed plates 3. The two fixed plates 3 are respectively fixed to the lower surface of the two support frames 2. The interior of each fixed plate 3 is threaded with two adjusting screws 31. The lower end of each adjusting screw 31 is fixed with a support seat 32, and the upper end of each adjusting screw 31 is fixed with a hand-tightening part 33.

[0033] Specifically, the adjustment mechanism includes a movable part 4, which is slidably mounted on the outer surface of the mounting bracket 1, and a mounting plate 41 is fixed on the lower surface of the movable part 4.

[0034] Furthermore, the movable part 4 facilitates the adjustment of the device, thereby making it easier to lift cables at different positions.

[0035] Specifically, a protective shell 42 is fixed to the lower surface of the mounting plate 41, and a steel rope roller 43 is installed inside the protective shell 42.

[0036] Furthermore, the protective shell 42 can protect the steel rope winding roller 43, thereby improving safety.

[0037] In use, the device can be moved to a suitable position by means of the casters on the fixed plate 3. By manually turning the adjustment screw 31 on the fixed plate 3 and turning the hand screw 33, the support base 32 can be driven to move vertically, so that the support base 32 contacts the ground, thereby supporting and limiting the device, effectively reducing the possibility of accidental movement of the device and improving stability.

[0038] In summary, when using this cable lifting device, the device can be easily moved to a suitable position. Tightening the hand-tightening part 33 can drive the support base 32 to move vertically, and the support base 32 contacts the ground, thereby supporting and limiting the device.

[0039] Example 2

[0040] Please see Figures 1-4 This is the second embodiment of the present utility model.

[0041] Specifically,

[0042] The steel rope roller 43 is externally connected to a steel rope body 44. A fixed hook 45 is fixed at the lower end of the steel rope body 44. Fixed bearings 46 are fitted at both ends of the steel rope roller 43. A limiting plate 47, which is fixedly connected to the protective shell 42, is fixed on the outer surface of the fixed bearing 46.

[0043] Furthermore, the steel rope reel 43 is driven by a motor to run, thereby causing the steel rope body 44 to retract or extend. By connecting the fixed hook 45 to the cable to be lifted, the cable can be lifted.

[0044] Specifically, the drive mechanism includes a walking motor 5, which is fixed to the inner wall of the mounting bracket 1 by bolts. The power output shaft of the walking motor 5 is fixed with a drive gear 51, and a fixed rack 52 meshes with one side of the drive gear 51.

[0045] Furthermore, the walking motor 5 can drive the drive gear 51 to rotate, so that the drive gear 51 meshes with the fixed rack 52. Since the fixed rack 52 is fixedly connected to the mounting bracket 1, it is convenient to adjust the device.

[0046] Specifically, two guide bars 53 are symmetrically fixed on the outer wall of the mounting bracket 1, and the outer sides of the two guide bars 53 are slidably connected to the limiting grooves 54 opened in the movable part 4.

[0047] Furthermore, the guide bar 53, in conjunction with the limiting groove 54, can play a guiding and limiting role, ensuring the stability of the moving part 4 during movement.

[0048] In use, the drive motor 5 inside the movable part 4 can drive the drive gear 51 to rotate through the mounting frame 1 on the support frame 2, so that the drive gear 51 meshes with the fixed rack 52. Since the fixed rack 52 is fixedly connected to the mounting frame 1, when the drive gear 51 meshes with the fixed rack 52, the drive motor 5 itself will drive the movable part 4 to move horizontally on the mounting frame 1, which facilitates the adjustment of the device. In addition, the guide bar 53, with the cooperation of the limiting groove 54, can play a guiding and limiting role, ensuring the stability of the movable part 4 during movement. Through the protective shell 42 on the mounting plate 41, the steel rope roller 43 is driven by an external motor to run, thereby driving the steel rope body 44 to retract or release. By connecting the fixed hook 45 to the cable to be lifted, the cable can be lifted. In addition, through the fixed bearing 46 on the steel rope roller 43, with the cooperation of the limiting plate 47, the stability of the steel rope roller 43 can be enhanced, thereby ensuring the stability when lifting the cable.

[0049] In summary, when using this cable lifting device, the device can be easily moved to a suitable position. Tightening the hand-tightening part 33 can drive the support base 32 to move vertically, and the support base 32 contacts the ground, thereby supporting and limiting the device. In addition, the device can easily lift the cable, making it convenient to use. The traveling motor 5 itself will drive the movable part 4 to move horizontally on the mounting frame 1, thereby facilitating the adjustment of the device.
