Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting device for a distribution box. Background Technology

[0002] As a key component of the power system, the installation and maintenance of distribution boxes are common operations in electrical engineering. During installation, especially at heights or in complex spaces, hoisting equipment is usually required to lift the heavy distribution boxes to their designated positions.

[0003] However, existing general-purpose hoisting tools, such as simple hooks or slings, often only provide vertical lifting capabilities, which are insufficient for the stable fixation and precise alignment of distribution boxes. Specifically, due to the diverse sizes and specifications of distribution boxes, general-purpose clamps are difficult to effectively and stably hold different models of distribution boxes, and swaying or tilting is prone to occur during operation, affecting installation accuracy and creating safety hazards. Furthermore, even if the distribution box is lifted to the approximate height, its final installation still requires millimeter-level precision alignment with the pre-drilled holes on the wall or bracket. Traditional hoisting methods often require manual secondary handling and laborious fine-tuning after lifting, a process that is not only labor-intensive but also inefficient and makes it difficult to guarantee installation quality. Therefore, existing technologies generally lack a dedicated hoisting device that integrates adaptive clamping and multi-dimensional positional fine-tuning functions, and cannot comprehensively solve the problems of stable fixation and precise alignment of distribution boxes of different sizes after hoisting.

[0004] Therefore, this utility model proposes a hoisting device for distribution boxes to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of distribution box hoisting devices that are incompatible with distribution boxes of different sizes and are difficult to precisely adjust after hoisting, resulting in limited functionality and inconvenient assembly, this utility model aims to provide a distribution box hoisting device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a hoisting device for a distribution box, including: a keel frame and a hoisting frame suspended below the keel frame; a fixing mechanism disposed on the hoisting frame and an adjusting mechanism connected between the keel frame and the hoisting frame.

[0007] The fixing mechanism includes a fixed side plate that can move synchronously towards or away from each other, and a driving component for driving the fixed side plate to move.

[0008] Furthermore, the adjustment mechanism is combined by driving the hoisting frame to perform horizontal reciprocating motion and vertical lifting motion relative to the keel frame.

[0009] Preferably, the adjustment mechanism includes a fixed block slidably connected to the keel frame, a rack horizontally fixed to the keel frame, and a gear rotatably mounted on the fixed block and meshing with the rack. The fixed block is also provided with a motor b that drives the gear to rotate via a rotating shaft b.

[0010] Preferably, the adjustment mechanism further includes a cylinder, which is connected between the fixed block and the lifting frame, and has a telescopic shaft that can extend and retract vertically to drive the lifting frame to rise and fall.

[0011] Preferably, the drive assembly includes a motor a, a transmission plate connected to the output shaft of motor a, and a sliding rod. One end of the sliding rod is hinged to the transmission plate, and the other end is connected to a fixed side plate, for converting the rotation of the transmission plate into the translation of the fixed side plate.

[0012] Preferably, the drive assembly further includes a rotating shaft a, which is connected between the motor a and the transmission plate.

[0013] Preferably, the fixing mechanism further includes a protective housing, in which the drive assembly and the sliding rod are housed, and the sliding rod is restricted to sliding within the protective housing.

[0014] Preferably, the fixing mechanism further includes a limiting post fixed to the hoisting frame and a rotating baffle rotatably disposed on the hoisting frame, the rotating baffle having a groove for engaging with the limiting post.

[0015] Preferably, the bottom of the hoisting frame is also provided with a plate for supporting the bottom of the distribution box.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem that existing hoisting devices cannot be compatible with distribution boxes of different sizes by setting a fixed side plate driven by a motor that can move synchronously in opposite directions or out of direction, and achieves the technical effect of being able to flexibly clamp distribution boxes of different specifications with strong applicability.

[0018] 2. This utility model solves the problem of difficulty in accurately aligning the distribution box after hoisting by setting up a gear and rack driven by a motor to achieve horizontal movement, and setting up an adjustment mechanism that drives a telescopic shaft with a cylinder to achieve vertical lifting. It achieves the technical effect of enabling precise micro-adjustment of the distribution box in multiple directions, significantly improving installation efficiency and docking accuracy.

[0019] 3. This utility model, by adding a locking structure of a rotating baffle and a limiting post to the existing fixed side plate clamping distribution box, solves the problem of potential loosening risk and insufficient safety of a single clamping method, and achieves the purpose of double limiting and fixing. This makes the distribution box more stable and reliable during hoisting and moving, and improves the overall operational safety. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a hoisting device for distribution boxes, which aims to solve the problems of existing distribution box hoisting devices being incompatible with distribution boxes of different sizes and lacking precise position adjustment functions after hoisting. Figure 1As shown, the hoisting device for the distribution box includes a frame 1 and a hoisting frame 2 suspended below the frame 1. The frame 1 serves as the support and guiding foundation for the entire device. The hoisting frame 2 is the core functional component that supports the distribution box. A fixing mechanism 4 for clamping the distribution box is installed on it. An adjustment mechanism 5 for driving the hoisting frame 2 to adjust its position is connected between the frame 1 and the hoisting frame 2. The bottom of the hoisting frame 2 is also provided with a plate 3 for supporting the bottom of the distribution box. Through the coordinated work of the fixing mechanism 4 and the adjustment mechanism 5, adaptive fixing and multi-directional precise adjustment of distribution boxes of different sizes can be achieved.

[0029] The core technical solution of the hoisting device for the distribution box lies in the fact that the adjusting mechanism 5 is connected between the keel frame 1 and the hoisting frame 2, forming a specific structural fit and connection relationship. Please refer to the following for details. Figure 1 , Figure 2 and Figure 4 The core structure is described in detail below. The adjustment mechanism 5 includes a fixed block 55 slidably connected to the keel frame 1. A rack 51 is horizontally fixed on the keel frame 1. A gear 54 that meshes with the rack 51 is rotatably mounted on the fixed block 55. A motor b52 is also fixedly connected to the fixed block 55. The motor b52 is connected to and drives the gear 54 to rotate through a rotating shaft b53. This meshing transmission structure of the gear 54 and the rack 51 converts the rotational motion output by the motor b52 into the horizontal reciprocating motion of the fixed block 55 along the keel frame 1. At the same time, the adjustment mechanism 5 also includes a cylinder 56 connected between the fixed block 55 and the hoisting frame 2. The cylinder 56 has a telescopic shaft 57 that can extend and retract vertically. The extension or retraction of the telescopic shaft 57 drives the hoisting frame 2 to rise and fall relative to the fixed block 55. Through the combination of horizontal and vertical motion, the multi-degree-of-freedom position adjustment of the hoisting frame 2 is realized.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions, which are provided as preferred embodiments. Figure 1 , Figure 2 and Figure 3The driving component 42 of the fixing mechanism 4 includes a motor a421, which is fixedly connected to the hoisting frame 2. The output end of the motor a421 is connected to and drives the rotating shaft a422 to rotate. The rotating shaft a422 is connected to the transmission plate 423. One end of the sliding rod 43 is hinged to the transmission plate 423, and the other end of the sliding rod 43 is connected to the fixed side plate 44, which can move synchronously towards or away from each other. As another preferred embodiment, the fixing mechanism 4 also includes a protective shell 41. The driving component 42 and the sliding rod 43 are housed inside the protective shell 41, and the sliding rod 43 is restricted to sliding within the protective shell 41. As yet another preferred embodiment, the fixing mechanism 4 also includes a limiting post 46 fixed to the hoisting frame 2. A rotating baffle 45 is rotatably provided on the hoisting frame 2, and the rotating baffle 45 is provided with a groove for engaging with the limiting post 46.

[0031] The working principle is as follows: When it is necessary to hoist the distribution box, firstly, the hoisting frame 2 is pushed towards the distribution box by moving the keel frame 1, so that the insertion plate 3 at the bottom of the hoisting frame 2 slides to the bottom of the distribution box and lifts it up. Then, the motor a421 in the fixing mechanism 4 is started. The motor a421 drives the transmission plate 423 to rotate via the rotating shaft a422. Since the transmission plate 423 is hinged to the sliding rod 43, and the sliding rod 43 is restricted to linear reciprocating motion inside the protective shell 41, the rotational motion of the transmission plate 423 is converted into the translational motion of the sliding rod 43, which in turn drives the fixed side plate 44 to move towards each other to clamp the distribution box. After clamping, the rotating baffle 45 is rotated so that the groove on it engages with the limiting post 46, realizing the secondary limiting and locking of the distribution box. When adjusting the position of the distribution box, the motor b52 in the adjustment mechanism 5 is started. The motor b52 drives the gear 54 to rotate via the rotating shaft b53. Since the gear 54 meshes with the rack 51 fixed on the keel frame 1, the fixed block 55 with the gear 54 installed moves horizontally along the keel frame 1, thereby driving the entire hoisting frame 2 to achieve precise left and right position adjustment. At the same time, the cylinder 56 connected between the fixed block 55 and the hoisting frame 2 is started, driving its telescopic shaft 57 to extend or retract, thereby realizing the up and down lifting of the hoisting frame 2 relative to the fixed block 55. Through the coordinated action of the fixing mechanism 4 and the adjustment mechanism 5, this utility model solves the problem that the hoisting device in the prior art cannot be compatible with distribution boxes of different sizes and lacks precise position fine adjustment function.
