Description

Technical Field

[0001] This utility model relates to the field of micro power equipment installation technology, and more specifically, to a micro power equipment hoisting device. Background Technology

[0002] Miniature electrical equipment generally refers to electrical equipment and systems that are small in size and have low power, mainly including miniature motors and miniature circuit breakers. Miniature circuit breakers (MCBs) are also known as small circuit breakers and are suitable for overload and short-circuit protection of AC 50 / 60Hz lines with rated voltage of 230 / 400V and rated current up to 63A. They can also be used for infrequent switching of lines under normal conditions. Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings, and are the most widely used terminal protection electrical appliances in building electrical terminal distribution devices.

[0003] A power equipment box often contains multiple miniature power devices. When the power equipment box is installed on top of a utility pole, workers need to hoist the miniature power devices to a location within easy reach. Since the number of miniature power devices that workers can carry at one time is limited, workers often need to climb up and down multiple times to retrieve them during installation, which is very troublesome. If large cranes or other hoisting equipment are used for hoisting, it will waste resources and increase installation costs, which is not convenient enough. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a miniature power equipment hoisting device, which has the advantages of safe and convenient use, thereby solving the problems mentioned in the background technology.

[0006] To achieve the aforementioned advantages of safe and convenient use, the specific technical solution adopted by this utility model is as follows:

[0007] A lifting device for miniature power equipment includes a fixed ring and a cantilever frame. One end of the fixed ring is hinged, and the other end of the fixed ring is provided with an ear plate. The ear plates are fixed together by a handle bolt. A cantilever frame is welded to one side of the fixed ring, and a guide wheel is rotatably connected to the inner side of the other end of the cantilever frame. A winding roller is provided between the cantilever frames. The winding roller is rotatably connected to the cantilever frame via a roller shaft. A handwheel is fixedly connected to one end of the roller shaft, and a ratchet is fixedly connected to the other end of the roller shaft. A side plate is fixedly installed on one side of the ratchet on the side wall of the cantilever frame, and a stop rod is slidably connected through the surface of the side plate. One end of the stop rod has an oblique opening, and the other end of the stop rod is fixedly connected to an end plate. A spring is sleeved between the end plate and the connecting plate outside the stop rod. A pull rope is wound on the surface of the winding roller, and the pull rope passes around the guide wheel and rolls against the guide wheel. The other end of the pull rope is connected to a basket.

[0008] Furthermore, the roller shaft passes through the cantilever frame and is rotatably connected to the cantilever frame via a bearing, and the roller shaft is fixedly connected to the take-up roller, and the roller shaft and the take-up roller are arranged coaxially.

[0009] Furthermore, the handle bolt is fitted with a nut.

[0010] Furthermore, the guide wheel is rotatably connected to the cantilever frame via an axle, and the axle passes through the cantilever frame and is rotatably connected to the cantilever frame via a bearing.

[0011] Furthermore, the cantilever frame has a groove-shaped structure, and both the cantilever frame and the fixing ring are made of aluminum alloy.

[0012] Furthermore, the two ends of the spring are fixedly connected to the end plate and the side plate, respectively.

[0013] Furthermore, a wristband is fixedly installed at the other end of the end plate, and the inner diameter of the wristband is greater than 5cm.

[0014] Furthermore, the pull rope is made of steel wire rope, and one end of the pull rope is fixedly connected to the surface of the take-up roller.

[0015] Compared with the prior art, the present invention provides a miniature power equipment hoisting device, which has the following beneficial effects:

[0016] (1) This utility model adopts a fixing ring and a winding roller. When hoisting micro power equipment, the staff can carry this device to a high position on the utility pole. Then, the fixing ring is opened and passed over the outer surface of the top of the utility pole. It is fixed by the handle bolt. Since the utility pole is thinner at the top and thicker at the bottom, and the diameter gradually decreases from bottom to top, the inner diameter of the fixing ring is 1-2mm larger than the outer diameter of the top of the utility pole. After moving down by gravity, it can reach the position where the diameter of the utility pole is equal to the inner diameter of the fixing ring. The fixing ring can then stop moving down and complete the fixing. After fixing, the staff can turn the handwheel to wind up the rope and drive the basket to rise. This allows for multiple hoisting of micro power equipment, saving the trouble of frequent up and down handling. At the same time, it avoids the problems caused by using large hoisting equipment, improves the convenience of use and work efficiency. In addition, this device is small in size and very convenient to carry and use.

[0017] (2) This utility model uses a ratchet and a stop rod. When the operator turns the handwheel counterclockwise to rewind the rope, the ratchet pushes one end of the stop rod outward, and the spring is compressed. The stop rod does not affect the counterclockwise rotation of the ratchet and does not affect the normal winding. After the operator stops turning the handwheel, one end of the stop rod is inserted into the ratchet tooth of the ratchet to prevent the ratchet from rotating in the opposite direction. The basket can then be suspended, which makes it convenient to pick up goods and prevents the basket from falling after the handwheel is released. This improves the convenience and safety of use.

This device addresses the issues arising from hoisting equipment, improving ease of use and work efficiency. Its compact size makes it easy to carry and use. When the operator turns the handwheel 8 counter-clockwise to rewind the rope 13, the ratchet 9 pushes one end of the stop lever 10 outwards, compressing the spring 17. The stop lever 10 does not affect the counter-clockwise rotation of the ratchet 9 or normal rewinding. After stopping the handwheel 8, one end of the stop lever 10 inserts into the ratchet teeth of the ratchet 9, preventing the ratchet 9 from rotating in the opposite direction. The basket 15 can then be suspended, facilitating the retrieval of goods while preventing the basket 15 from falling if the handwheel 8 is released, thus improving both ease of use and safety.

[0028] In one embodiment, the roller shaft 7 passes through the cantilever frame 5 and is rotatably connected to the cantilever frame 5 via a bearing. The roller shaft 7 is fixedly connected to the take-up roller 6, and the roller shaft 7 and the take-up roller 6 are arranged coaxially to improve the rotational stability of the take-up roller 6.

[0029] In one embodiment, the guide wheel 14 is rotatably connected to the cantilever frame 5 via an axle, and the axle passes through the cantilever frame 5 and is rotatably connected to the cantilever frame 5 via a bearing, thereby improving the stability of the rotation of the guide wheel 14.

[0030] In one embodiment, the cantilever 5 has a groove-shaped structure, and both the cantilever 5 and the fixing ring 1 are made of aluminum alloy, which is lightweight, structurally stable, high-strength, and easy to carry.

[0031] In one embodiment, the two ends of the spring 17 are fixedly connected to the end plate 16 and the side plate 11 respectively to prevent the stop rod 10 from falling off and to play the role of elastic connection.

[0032] In one embodiment, a wristband 12 is fixedly installed on the other end of the end plate 16, and the inner diameter of the wristband 12 is greater than 5cm, so that it is convenient for the staff to pull. When the staff pulls the wristband 12 and the end plate 16 outward, the stop rod 10 releases the limit on the ratchet 9, and the basket 15 can be lowered.

[0033] In one embodiment, the pull rope 13 is made of steel wire rope, and one end of the pull rope 13 is fixedly connected to the surface of the take-up roller 6 to prevent the pull rope 13 from detaching from the take-up roller 6.

[0034] Working principle:

[0035] When hoisting miniature power equipment, workers can carry this device to a high point on a utility pole. Then, they can open the fixing ring 1, pass it around the top outer surface of the pole, and secure it using the handle bolt 2. Because the pole is thinner at the top and thicker at the bottom, with its diameter decreasing from bottom to top, the inner diameter of the fixing ring 1 is 1-2mm larger than the outer diameter of the top of the pole. Under gravity, the device will descend until it reaches a position where the pole's diameter equals the inner diameter of the fixing ring 1, at which point the fixing ring 1 will stop descending, completing the fixation. After securing, workers can rotate the handwheel 8 to rewind the pull rope 13, raising the basket 15. This allows for multiple hoistings of the miniature power equipment, eliminating the hassle of frequent lifting and lowering. This design avoids the problems associated with using large hoisting equipment, improves ease of use and work efficiency. Furthermore, the device is compact and easy to carry and use. When the operator turns the handwheel 8 counterclockwise to rewind the rope 13, the ratchet 9 pushes one end of the stop lever 10 outwards, compressing the spring 17. The stop lever 10 does not affect the counterclockwise rotation of the ratchet 9 or the normal rewinding. After the operator stops turning the handwheel 8, one end of the stop lever 10 inserts into the ratchet teeth of the ratchet 9, preventing the ratchet 9 from rotating in the opposite direction. The basket 15 can then be suspended, facilitating the retrieval of goods while preventing the basket 15 from falling if the handwheel 8 is released, thus improving both ease of use and safety.
