Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and particularly relates to a mosquito-repellent incense coil hanger. Background Art

[0002] A hanger refers to a device for lifting heavy objects in a hoisting machine. The most commonly used hangers for lifting finished items are hooks and slings. Others include eyebolts, lifting suction cups, tongs, and forklift tines, etc. They are widely used in the hoisting and lifting industry.

[0003] Since the mosquito-repellent incense coil made of copper pipe is relatively heavy, equipment such as a hanger is needed to carry it. However, generally, the surface of the coiled mosquito-repellent incense coil is wound with copper pipes. When hoisting it, it needs to be hoisted through a material placing plate to avoid hoisting by tying with straps, which is likely to damage the copper pipes on the side. Therefore, a new type of hanger is developed. Content of the Utility Model

[0009] Preferably, a cross hinge plate is arranged below the bottom shaft sleeve. The cross hinge plate and the bottom shaft sleeve are connected to each other by screws. A base is arranged below the cross hinge plate. The side of the base is inserted into a plurality of second limiting rods. A guiding shaft is inserted upward at the central position of the base. The guiding shaft is slidably inserted into the cross hinge plate. Third connecting arms are rotatably connected to the four ends of the cross hinge plate. A fourth connecting arm is arranged at the bottom of each third connecting arm.

At the same time, it can also play a role in limiting the mosquito coil trays on the material placing tray to prevent them from falling. By opening through holes at the connection between the material placing tray and the main shaft, and a clamping groove is opened below the through holes. When the locking device below the main shaft is inserted into the through holes, the mini cylinder of the locking device drives the punching rod to drive the bottom shaft sleeve and the cross hinge plate below to lift synchronously, thereby driving the third connecting arm to press down. Since the middle section of the fourth connecting arm at the bottom of the third connecting arm is hinged to the hinge seat on the base, when the top is lifted upwards, its bottom unfolds outwards along the cross groove of the base, making the buckle on the outer side of the second connecting arm engage with the clamping groove on the material placing tray. When the entire device is hoisted, the locking device can lock the material placing tray, making the overall handling more stable and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Principle of the present utility model: After the mosquito-repellent incense tray 4 is placed at the four corners on the top of the material placing tray 1, the hoist 21 at the top is hoisted by the hoist chain 24 and a hoist or a traveling crane at this time. After moving above the material placing tray 1, the entire hoist 21 descends at this time. With the cooperation of workers below, the locking device at the bottom is aligned and inserted into the through hole at the center of the material placing tray 1. The side of the base 313 at the bottom is stuck on the top of the material placing tray 1. The protruding part at the bottom of the base 313 extends along the through hole to one side of the card slot 11. At the same time, the hoist 21 above the main shaft 3 continues to descend, so that the top hoist 21 drives the main shaft 3 and the top shaft sleeve 31 below the main shaft 3 to descend. The proximity switches 316 in the installation grooves 315 on both sides of the bottom shaft sleeve 32 descend synchronously, so as to move away from the contact piece 34 above. At this time, the proximity switch 316 transmits a signal to the controller, and then the controller controls the mini cylinder 38 and the telescopic mechanism 27 to be turned on respectively;

[0026] The telescopic mechanism 27 drives one end of the second connecting arm 26 at the output end to move downward, so that the pressing tray 23 and the sleeve 22 rotatably connected to the bottom of the second connecting arm 26 move downward along the main shaft 3, and can continuously press down on a plurality of mosquito-repellent incense trays 4 above the material placing tray 1, so as to have better stability during transportation.

[0027] When the mini cylinder 38 below is turned on, it drives the punching rod 39 at the output end to pass through the bottom shaft sleeve 32 to above the cross hinge plate 310, and at the same time pulls up the bottom shaft sleeve 32. Since the cross hinge plate 310 and the bottom shaft sleeve 32 are fixedly connected by bolts, the cross hinge plate 310 is driven to move upward. At this time, a plurality of third connecting arms 311 rotatably connected to the side of the cross hinge plate 310 move upward. One end of the fourth connecting arm 312 below the third connecting arm 311 retracts inward. The middle section near the top of the fourth connecting arm 312 is rotatably connected to the hinge seat 3131 on the base 313. Therefore, when the top of the fourth connecting arm 312 moves inward, due to the hinge of the hinge seat 3131 near the upper middle section, the lower part of the fourth connecting arm 312 turns outwards, so that the buckle 3121 at the bottom of the fourth connecting arm 312 is engaged with the card slot 11 on the material placing tray 1 to complete the clawing of the material placing tray 1. At this time, the equipment of the hoist 21 for overhead lifting above drives the entire hoist 21 to move upward, so that the entire equipment can grab the entire material placing tray 1 and rise, facilitating the overall transportation.

[0028] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model should be considered to fall within the protection scope of the present utility model.
