Description

Technical Field

[0001] This utility model relates to the field of rotating lifting equipment technology, and in particular to a wireless remote-controlled rotating lifting equipment. Background Technology

[0002] Lifting slings are widely used lifting devices in lifting operations. Many heavy workpieces need to be connected horizontally in the air. The storage position before assembly is inconsistent with the position during assembly, so rotation and alignment are required before connection and assembly. Existing rotating lifting slings are generally powered by external power lines, which makes wiring control cumbersome and electrical safety unsafe. Utility Model Content

[0003] The purpose of this invention is to provide a wireless remote-controlled rotating lifting device. The device can rotate and its angle can be freely adjusted. It also increases the load capacity of the rotating motor and expands the applicability of the rotating lifting device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A wireless remote-controlled rotating hoist includes a main frame, a battery, a slewing lower support, a hook seat, and a hook. A power distribution box is fixedly mounted on the main frame. A battery compartment is fixedly mounted on each of the left and right sides of the main frame. A slide rail is provided inside each battery compartment along the front-to-back direction. A bracket is slidably connected to the slide rail and supports the battery. Two batteries are connected in series to power the power distribution box. The power distribution box is equipped with a remote control receiver and a motor speed controller. A rotary motor is fixedly mounted on each of the front and rear sides of the main frame. The rotary motor is controlled by the motor speed controller and drives the slewing lower support to rotate. The upper end of the hook seat is hinged to the lower end of the slewing lower support via a pin, and the upper end of the hook is hinged to the lower end of the hook seat via a pin.

[0006] Furthermore, the distribution box is equipped with a DC voltage converter, and the battery is a 48V lithium battery. The DC voltage converter converts the DC 48V of the battery into DC 24V to power the distribution box.

[0007] Furthermore, the wireless remote-controlled rotating hoist includes a remote-controlled transmitter, which is connected to the remote-controlled receiver via a wireless signal. The remote-controlled transmitter is equipped with a start / stop button, a hook forward rotation button, and a hook reverse rotation button. The start / stop button controls the start and stop of the rotating motor, and the hook forward rotation button and hook reverse rotation button control the forward and reverse rotation of the rotating motor.

[0008] Furthermore, the remote transmitter is equipped with an emergency stop button, which controls the remote receiver to cut off the power supply to the distribution box.

[0009] Furthermore, two slide rails are provided on the left and right sides inside the battery compartment, and the left and right sides of the bracket are slidably connected to the two slide rails respectively.

[0010] Furthermore, a slewing bearing is provided between the rotary motor and the lower slewing support. The inner ring of the slewing bearing is fixedly connected to the main frame, the outer ring of the slewing bearing meshes with the output pinion of the rotary motor, and the upper end of the lower slewing support is fixedly connected to the outer ring of the slewing bearing.

[0011] Furthermore, two locking clips are provided on the left and right sides of the front end of the bracket, and the locking clips limit the front end of the battery.

[0012] Furthermore, the bracket is provided with several fixing clips, which limit the left and right ends and the top end of the battery.

[0013] Furthermore, the fixing clip is n-shaped, and the left and right sides of the bracket are provided with insertion holes. The left and right ends of the fixing clip pass through the insertion holes and are fixedly connected to the lower end of the bracket by bolts.

[0014] Furthermore, two balancing frames are provided on the left and right sides of the upper end of the main frame.

[0015] In this utility model of a rotating lifting device, a rotating motor drives a slewing lower support to rotate, and the rotation of the slewing lower support drives the hook seat and the hook to rotate, enabling the hook to rotate. The slewing lower support increases the weight that the output shaft of the rotating motor can bear, giving the hook higher stability when rotating.

[0016] In this utility model of a rotary lifting device, the hook is hinged to the hook seat, and the hook seat is hinged to the slewing lower support, so that the hook can be freely adjusted in angle, enabling the lifting device to lift workpieces under various working conditions and angles, thus expanding the application range of the rotary lifting device;

[0036] like Figure 2 As shown, the distribution box 10 is equipped with a DC voltage converter 20, and the battery 11 is a 48V lithium battery. The DC voltage converter 20 converts the DC 48V of the battery 11 into DC 24V to power the distribution box 10. The distribution box is equipped with 2PC100A and 2PC50A air switches. When the current exceeds the rated current, the air switches will automatically disconnect the power supply circuit of the distribution box 10.

[0037] like Figure 3 As shown, two batteries 11 are connected in series with a power line and a data line to supply power to the distribution box 10. The two batteries 11 share a charging interface, and the positive and negative discharge terminals of the two batteries 11 are connected to the discharge interface.

[0038] like Figure 2 As shown, the distribution box 10 is equipped with a remote control receiver 18, and a rotary motor 8 is fixed on the front and rear sides of the main frame 2 respectively.

[0039] The wireless remote-controlled rotating hoist in this embodiment also includes a remote control transmitter 21, which is connected to the remote control receiver 18 via a wireless signal, such as...

The distribution box is also equipped with a motor speed controller 19, and the rotating motor 8 is controlled by the motor speed controller 19 to control the rotation direction and speed.

[0041] like Figure 1 and Figure 5 As shown, the inner ring of the slewing bearing 4 is fixedly connected to the main frame 2, the outer ring of the slewing bearing 4 meshes with the pinion at the output end of the rotary motor, the upper end of the lower slewing support 5 is fixedly connected to the outer ring of the slewing bearing 4, the upper end of the hook seat 6 is hinged to the lower end of the lower slewing support 5 through a pin, and the upper end of the hook 7 is hinged to the lower end of the hook seat 6 through a pin, thereby realizing the rotation of the hook 7.

[0042] like Figure 6As shown, the mounting structure of the bracket 13 includes two locking clips 14 and two fixing clips 15. The two locking clips 14 are located on the left and right sides of the front end of the bracket 13, and the two locking clips 14 respectively limit the front end of the left and right sides of the battery 11. The two fixing clips 15 are located in the middle of the bracket 13. The fixing clips 15 have an n-shaped structure and limit the left and right ends and the top end of the battery 11.

[0043] like Figure 6 As shown, the fixing clip 15 includes a ratchet tensioner 151 and a cloth belt 152. When the battery 11 is installed, the cloth belt 151 is wrapped around the left and right sides and the top of the battery 11 in an n-shape. The ratchet tensioner 151 tightens the cloth belt 152 to position the battery 11.

[0044] The bracket 13 has two insertion holes on its left and right sides. The left and right ends of the fixing clip 15 pass through the two insertion holes and are bent horizontally at the lower end of the bracket 13. The horizontally bent part at the lower end of the fixing clip 15 is then fixedly connected to the lower end of the bracket 13 by bolts.

[0045] like Figure 6 As shown, two sliders 16 are fixed on the left and right sides of the rear of the bracket 13. The sliders 16 extend backward and protrude from the rear end of the bracket 13 for easy guidance. The slide rail 12 is an n-shaped track with the opening facing outward.
