Description

Technical Field

[0001] The utility model relates to the technical field of electric loader power transmission, in particular to a cable-type electric loader cable automatic retracting and releasing device. Background Art

[0002] An electric loader is a loader that uses electricity as its power source. Therefore, when an electric loader is working, it must first ensure that the power supply is sufficient. There are two conventional power supply methods, one is to connect to the mains through a cable, and the other is to supply power through a battery.

[0003] At present, the power supply method of connecting to the mains through cables requires a sufficiently long cable, and the length of the cable must be sufficient to allow the loader to move freely in the working area. Due to the long cable, the electric loader using this power supply method needs to wrap the cable around a cable winch so that the cable can be flexibly retracted and released as the loader moves.

[0004] In the prior art, the cable is generally retracted and released by an electric cable winch, but the working motor of the cable winch is not synchronized with the travel direction and speed of the loader, resulting in untimely and asynchronous cable retraction and release, which causes inconvenience to the normal operation of the loader. Utility Model Content

[0005] In order to overcome the technical defects in the prior art and effectively solve the technical problems in the background technology, the utility model provides the following technical solutions:

[0006] A cable-type electric loader cable automatic retracting and releasing device comprises a base, a fixing frame is fixedly mounted on the upper surface of the base, a rotating seat is rotatably connected to the upper surface of the fixing frame, brackets are symmetrically fixedly mounted on both ends of the upper surface of the rotating seat, a rotating shaft is rotatably connected between the two brackets, a cable retracting and releasing reel is fixedly mounted on the middle part of the outer side of the rotating shaft, a cable is correspondingly wound around the cable retracting and releasing reel, a wire rope retracting and releasing reel is fixedly mounted on one end of the outer side of the shaft, a wire rope is correspondingly wound around the wire rope retracting and releasing reel, and a weight is fixedly mounted on one end of the wire rope extending below the rotating seat.

[0007] As a preferred technical solution of the utility model, a turntable is rotatably connected to the center of the upper surface of the fixed frame via a bearing, and the upper surface of the turntable is fixedly connected to the center of the bottom of the rotating seat.

[0008] As a preferred technical solution of the utility model, a fixed block is fixedly installed on one side of the bottom of the rotating seat, a pulley is fixedly installed on the upper surface of the weight, one end of the wire rope is fixedly installed on the bottom of the fixed block, and the other end of the wire rope passes through the pulley and is wound on the wire rope reel.

[0009] As a preferred technical solution of the utility model, a through groove is provided on the upper surface of the rotating seat directly below the wire rope reel, and the wire rope between the wire rope reel and the pulley passes through the through groove accordingly.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the automatic cable retracting and releasing device of the cable-type electric loader has a reasonable and practical structure, is easy to operate, and can realize synchronous retracting and releasing of the cable retracting and releasing reel that matches the traveling direction and speed of the loader. The cable retracting and releasing reel is timely and synchronous, which provides convenience for the normal operation of the loader; specifically, the loader pulls the cable to drive the rotation of the cable retracting and releasing reel to perform the reeling operation, and at the same time drives the rotation and reeling of the wire rope retracting and releasing reel, driving the rise of the weight. When the loader moves and needs to be reeled, the weight automatically descends under the action of gravity, pulling the wire rope to drive the wire rope retracting and releasing reel to rotate and reel, and at the same time drives the cable retracting and releasing reel to rotate to perform the reeling operation.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: an automatic cable retracting and releasing device for a cable-type electric loader, comprising a base 1, a fixing frame 2 is fixedly installed on the upper surface of the base 1, a rotating seat 5 is rotatably connected to the upper surface of the fixing frame 2, brackets 6 are symmetrically fixedly installed on both ends of the upper surface of the rotating seat 5, a rotating shaft 7 is rotatably connected between the two brackets 6, a cable retracting and releasing reel 8 is fixedly installed in the middle of the outer side of the rotating shaft 7, a cable 9 is correspondingly wound on the cable retracting and releasing reel 8, a wire rope retracting and releasing reel 10 is fixedly installed at one end of the outer side of the shaft 7, a wire rope 11 is correspondingly wound on the wire rope retracting and releasing reel 10, and a weight 12 is fixedly installed on one end of the wire rope 11 extending below the rotating seat 5.

[0018] Further, such as Figure 2 As shown, the center of the upper surface of the fixed frame 2 is rotatably connected to a turntable 4 through a bearing 3, and the upper surface of the turntable 4 is fixedly connected to the center of the bottom of the rotating seat 5. The turntable 4 can drive the rotating seat 5 to rotate horizontally, which is more convenient for the loader to move the reel at different angles.

[0019] Further, such as Figure 4 As shown, a fixed block 13 is fixedly installed on one side of the bottom of the rotating seat 5, a pulley 14 is fixedly installed on the upper surface of the weight 12, one end of the wire rope 11 is fixedly installed on the bottom of the fixed block 13, and the other end of the wire rope 11 passes through the pulley 14 and is wound on the wire rope reel 10. The pulley 14 assists the wire rope 11 to drive the weight 12 to move up and down.

[0020] Further, such as Figure 3 As shown, a through slot 15 is provided on the upper surface of the rotating seat 5 just below the wire rope reel 10, and the wire rope 11 between the wire rope reel 10 and the pulley 14 passes through the through slot 15 accordingly, which facilitates the limiting and up and down reeling of the wire rope 11.

[0021] When using:

[0022] First, the end of the cable 9 away from the cable reel 8 is fixedly connected to the corresponding loader and electrically connected, and the other end of the cable 9 is electrically connected to the external power supply. The principle is an existing mature technology and will not be described in detail here.

[0023] Then, the loader pulls the cable 9, driving the cable reel 5 to rotate, and the unwinding operation can be performed, and at the same time, it drives the wire rope reel 10 to rotate and rewind, driving the weight 12 to rise. When the loader moves and needs to rewind, the cable 9 loses tension. At this time, the weight 12 automatically descends under the action of gravity, pulling the wire rope 11 to drive the wire rope reel 10 to rotate and unwind, and at the same time drives the cable reel 5 to rotate, and the rewinding operation can be performed. In summary, the cable reel 5 can be synchronized with the loader's traveling direction and speed. The cable reel is timely and synchronous, which provides convenience for the normal operation of the loader.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
