Description

Technical Field

[0001] This utility model relates to the field of wire rope equipment technology, specifically to an automatic rope release device for a wire rope tray. Background Technology

[0002] Steel wire ropes are generally made of carbon steel wire with a circular cross-section and a diameter of 0.1 to 6.0 mm. The variety of steel wire ropes is also increasing, and their structure is becoming more and more complex. In addition to various coated steel wires, stainless steel wire and bimetallic steel wire are also used. Therefore, the weight of steel wire ropes varies depending on the materials used. A single spool of steel wire rope can weigh anywhere from a few tons to tens of tons. As a result, when steel wire ropes are lifted by a crane, due to gravity, it can be difficult to pull out the desired length by rotating the steel wire rope tray.

[0003] Currently, the common method for retrieving wire rope pallets when they are being lifted is manual rotation. When releasing a large number of meters, manual rotation consumes a lot of physical strength, resulting in high work intensity and decreased efficiency as physical strength decreases. In addition, when manually rotating wire rope pallets, the status of the hook above must be constantly monitored to prevent it from falling off. Furthermore, due to the excessive weight of a single spool of wire rope, the rotation speed needs to be manually controlled. Otherwise, there is a risk of the wire rope twisting during spool release, potentially catching personnel's hands. Moreover, rapid rotation can exacerbate pallet breakage, leading to the wire rope pallet shattering and falling, causing injury or death. Utility Model Content

[0022] The technical solution adopted by this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, this utility model provides an automatic rope unloading device for a wire rope tray, wherein the wire rope tray is an existing structure, such as... Figure 2 As shown, it includes: a central shaft 1 and trays 2 fixedly installed at both ends of the central shaft 1, with steel wire ropes wound on the central shaft 1;

[0024] The automatic rope feeding device is provided with a support platform 3 for supporting the pallet 2. The support platform 3 has a turntable 4 inside, so that the entire wire rope pallet can rotate on the turntable 4 relative to the support platform 3. A drive device is provided below the support platform 3 for driving the entire wire rope pallet to rotate around the central axis 1 on the support platform 3.

[0025] Specifically, in this embodiment, the support platform 3 can be a box with an inner cavity formed by welding steel plates, and the top plate of the box can serve as the support platform 3; or the support platform 3 can be configured as a platform and multiple support legs fixedly set on the end face of the platform, so that the platform can be supported on the ground by multiple support legs. The space enclosed between the multiple support legs can be used to set the drive device, so as to facilitate the movement of the entire automatic rope releasing device and the installation and maintenance of the drive device.

[0026] Turntable 4 can be a plane bearing;

[0027] The drive device for driving the entire wire rope tray to rotate includes: a positioning rod 6 set at the center of the turntable 4, the axis of the positioning rod 6 being perpendicular to the turntable 4, the bottom end of the positioning rod 6 being fixedly connected to the output shaft of the motor 5 through a reducer, and the motor 5 being fixedly set below the support platform 3, such as by connecting the flange and bolts to fix the motor 5 below the support platform 3.

[0028] The top of the positioning rod 6 is detachably equipped with a locking device for fixing the wire rope tray. The positioning rod 6 can be fixed to the wire rope tray by the locking device.

[0029] like Figure 3 As shown, during installation and use, this utility model can use lifting equipment to lift the wire rope tray and insert the central shaft 1 of the wire rope tray into the positioning rod 6, so that the tray 2 on one side of the wire rope tray sits on the turntable 4. Then, the locking device at the top of the positioning rod 6 is installed, and the positioning rod 6 is fixed to the wire rope tray by the locking device. By starting the motor 5, the positioning rod 6 can be driven to rotate the wire rope tray on the turntable 4 in the support platform 3. The operator only needs to coil the wire rope that has been turned out on the rotating wire rope tray. After reaching the desired number of meters, the motor 5 can be controlled to stop rotating, and the coiled wire rope can be cut off to complete the entire rope laying operation.

[0030] Furthermore, a holding brake can be installed on the output shaft of motor 5. By controlling the opening and closing of the holding brake, the output shaft of motor 5 can be automatically locked when motor 5 is de-energized, preventing the wire rope tray from rotating too much due to inertia.

[0031] In this embodiment, the locking device is provided with a positioning block 7 that can be sleeved on the positioning rod 6. The end face of the positioning block 7 is provided with a positioning bolt 8 that is threadedly connected to it. The positioning rod 6 is provided with a positioning groove 9 that matches the end of the positioning bolt 8. The positioning bolt 8 provided on the end face of the positioning block 7 can be screwed in so that the end of the positioning bolt 8 is inserted into the positioning groove 9, thereby realizing the installation of the locking device and the positioning rod 6. At the same time, the wire rope tray can be fixed from the axial direction of the positioning rod 6, and can be removed otherwise.

[0032] Preferred, such as Figure 4 As shown, the positioning groove 9 can be extended along the axial direction of the positioning rod 6 to form a positioning slide to accommodate the fixing of wire rope trays of different sizes.

[0033] Meanwhile, the positioning block 7 is also provided with multiple fixing arms 10 perpendicular to the axis of the positioning rod 6. The interior of the fixing arm 10 is provided with a slide rail perpendicular to the axis of the positioning rod 6. A fixing plate 11 is slidably provided in the slide rail. The end face of the fixing arm 10 away from the positioning block 7 is provided with a fixing bolt 12 that is threaded to it. The end of the fixing bolt 12 inserted into the fixing arm 10 is fixedly connected to the fixing plate 11. The position of the fixing plate 11 in the slide rail inside the fixing arm 10 can be adjusted by turning the fixing bolt 12 at the end of the fixing arm 10. The bottom end of the fixing plate 11 is provided with a protrusion. When the fixing plate 11 moves along the fixing arm 10, the protrusion at the bottom end of the fixing plate 11 can abut against the outer wall of the support plate 2 to fix the support plate 2 of the wire rope pallet.

[0034] Furthermore, the shape of the protrusion is preferably matched with the shape of the outer wall of the tray 2. For example, when the tray 2 is circular, the shape of the protrusion is a minor arc so that the two can make a more firm contact when they are pressed together.

[0035] In addition, the multiple fixed arms 10 are preferably arranged symmetrically relative to the positioning block 7 or evenly distributed around the positioning block 7 to further improve the reliable connection to the outer wall of the pallet 2.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
