DETAILED DESCRIPTION
[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.
[0016] like Figure 1 As shown in FIG10 , the present invention provides a single-beam electric four-point unhooking sling, comprising a main beam 1 and end beams 2 on both sides, wherein a fixed lifting point 6 is fixedly arranged at both ends of the lower end faces of the end beams 2 on both sides, and a detachable sling 7 is arranged on each fixed lifting point 6, and the same releasing mechanism is arranged inside the main beam 1 and the end beams 2 on both sides, and the releasing mechanism comprises two releasing rods 4, which are rotatably arranged inside the end beams 2 on both sides, and the two releasing rods 4 are connected by a connecting rod 8; a hanging rod 5 is fixedly arranged at both ends of the front and rear ends of each release rod 4, and the hanging rod 5 is hooked with one end of the sling 7 away from the fixed lifting point 6.
[0017] The main beam 1 is a square box structure arranged horizontally on the left and right sides, and the end beam 2 is a square box structure arranged horizontally on the front and back sides. The left and right ends of the main beam 1 are respectively fixedly connected to the middle of the end faces of the two end beams 2 that are close to each other. Two left-right symmetrical hanging points are fixedly arranged on the upper end face of the main beam 1, and a hook 3 is respectively arranged on the two hanging points, and the hoisting device is hoisted as a whole by the two hooks 3.
[0018] The release rod 4 is horizontally arranged along the front-to-back direction, and the front and rear ends of the release rod 4 extend outwardly from the front and rear end surfaces of the end beam 2. The hanging rod 5 is kept vertical to the release rod 4. When the hanging rod 5 is kept horizontal in the front-to-back direction, the end of the sling 7 away from the fixed hanging point 6 is hooked with the hanging rod 5; when the hanging rod 5 is rotated to a downward vertical state, the end of the sling 7 away from the fixed hanging point 6 is separated from the hanging rod 5, and the sling 7 is in a released state.
[0019] The connecting rod 8 is horizontally arranged at the front end surface of the main beam 1 along the left-right direction, and the left and right ends of the connecting rod 8 extend to the inside of the two end beams 2. A fixing rod 10 is fixedly arranged in the middle of the two release rods 4, respectively. The two fixing rods 10 remain parallel, and the ends of the two fixing rods 10 away from the release rod 4 are respectively hinged to the left and right ends of the connecting rod 8. Two left-right symmetrical limiting rods 11 are hinged in the middle of the connecting rod 8, the two limiting rods 11 are located below the connecting rod 8, and the two limiting rods 11 are parallel to the two release rods 4. Two groups of left-right symmetrical limiting seats 12 are fixedly arranged on the front end surface of the main beam 1, and the two groups of limiting seats 12 correspond to the two limiting rods 11 respectively; each group includes two left-right symmetrical limiting seats 12, and the two limiting seats 12 are respectively located on the left and right sides of the corresponding limiting rod 11, and the left and right rotation angles of the limiting rod 11 are limited by the two limiting seats 12.
[0020] An electric unhooking device 13 is arranged inside the left end beam 2. An action rod 14 is fixedly arranged on the left limit rod 11. The action rod 14 and the left limit rod 11 are located on the same straight line and the action rod 14 is located on the upper side of the connecting rod 8. A control rod 15 is arranged between the action rod 14 and the electric unhooking device 13. One end of the control rod 15 is hooked with the electric unhooking device 13, and the other end of the control rod 15 is hinged with the upper end of the action rod 14. The control rod 15 is parallel to the connecting rod 8.
[0021] A rotatable screw rod 16 and a driving motor 17 are respectively arranged inside the two end beams 2. The screw rod 16 is arranged horizontally along the front-back direction. The output shaft of the driving motor 17 is connected to the screw rod 16 in a transmission manner, and the screw rod 16 is driven by the driving motor 17 to rotate. A slide groove is respectively arranged on the end surface of the front and rear sides of each end beam 2. A latch 18 is respectively arranged inside each slide groove to slide along the front-back direction. The two latches 18 are respectively screwed to the front and rear ends of the screw rod 16 on the same side. When the two latches 18 extend to the outside of the slide groove, the hanging rods 5 at the front and rear ends of the release rod 4 are respectively overlapped on the front and rear latches 18, so that the two hanging rods 5 remain in a horizontal state; when the two latches 18 extend to the inside of the slide groove, the hanging rods 5 at the front and rear ends of the release rod 4 lose the support of the front and rear latches 18, and at this time, the hanging rods 5 at the front and rear ends of the release rod 4 can be rotated downward to a vertical state.
[0022] The working principle of the present invention is: Before lifting, the four lifting straps 7 are fixed to the four fixed lifting points 6 through the lifting rings respectively. At this time, the two pins 18 on the end beam 2 extend into the slide groove, and the hanging rods 5 at the front and rear ends of the release rod 4 lose the support of the two front and rear pins 18, and the ends of the four lifting straps 7 away from the fixed lifting point 6 are sleeved on the outside of the four hanging rods 5.
[0023] Then, the two driving motors 17 are controlled to start rotating, and the two driving motors 17 drive the two screw rods 16 to rotate. Since the screw rods 16 are threadedly connected to the front and rear pins 18, the front and rear pins 18 are driven to slide toward the outside of the slide slot until the hanging rods 5 at the front and rear ends of the release rod 4 are respectively overlapped on the front and rear pins 18. The front and rear pins 18 support the hanging rods 5 at the front and rear ends of the release rod 4 to ensure that the hanging rods 5 will not rotate or encounter other unexpected situations during the lifting process.
[0024] The lifting equipment lifts the whole sling through the hook 3, and the sling lifts the materials through the four slings 7 until it moves to the release location. When arriving at the release location, the two driving motors 17 are controlled to rotate in the opposite direction, so that the latch 18 is retracted into the inside of the slide slot, and the hanging rods 5 at the front and rear ends of the release rod 4 lose the support of the two front and rear latches 18. At this time, the hanging rods 5 at the front and rear ends of the release rod 4 can be rotated downward to a vertical state. Then the electric unhooking device 13 is controlled to start unhooking. After the control rod 15 loses the pulling force of the electric unhooking device 13, the hanging rod 5 starts to rotate downward under the action of the sling 7 and the gravity of the materials, so that the end of the sling 7 away from the fixed lifting point 6 is separated from the hanging rod 5, and then the materials are separated from the sling 7. When the materials are separated from the four slings 7, the overall release of the materials is completed.
[0025] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
