[0019] like Figure 1-5 As shown, a 3-ton load accumulation and delivery conveying equipment includes a traction track 1 and a load-bearing track 2 arranged from top to bottom, wherein two load-bearing tracks 2 are provided and arranged in a herringbone shape for the traction track 1. The traction track 1 is made of GB / T706-1988-10# I-steel, and the track material is 16Mn, and the load-bearing track 2 is made of GB / T706-1988-14# I-steel, and the track material is 16Mn.

[0020] A chain 3 is provided between the traction track 1 and the load-bearing track 2. The chain 3 rolls along the traction track 1 through a traction wheel 10 installed on the traction track 1. The traction chain adopts the internationally universal X-678 die-forged detachable chain, with a chain pitch of 153.2 mm (6”), a chain ultimate tensile strength of 386 KN, an allowable tensile load of 27 KN, a safety factor greater than 14 times, and a load capacity of 3 tons. The chain 3 is driven by a driving device, which includes a motor and a reducer. A push rod 4 is installed on the chain 3.

[0021] The load-bearing track 2 is provided with a plurality of moving vehicle groups, each of which includes two trolleys 5, and the trolleys are divided into a front trolley and a rear trolley. A suspension assembly 6 is connected between the two trolleys 5, and the suspension assembly is located below the trolley 5. A sling 11 for lifting a workpiece is hung on the suspension assembly 6. The sling 11 includes a hook 12 and a cross frame 13, and the cross frame 13 is fixed on the suspension assembly 6. The cross frame 13 is provided with a plurality of evenly distributed hooks, and the top end of the hook 12 is hung on the hook.

[0022] A lifting claw 7 is vertically inserted in the middle of the front and rear wheels of the trolley. The lifting claw is an integral precision casting made of ZG40Mn2 steel, and its working surface is heat-treated to ensure its strength and impact resistance.

[0023] The vertical section of the lifting claw 7 is inserted into the slot inside the trolley, and the vertical section of the lifting claw 7 can move up and down in the slot. A clamping slot 8 for clamping the push rod 4 is provided at the top of the lifting claw 7. The bottom of one end of the horizontal section of the lifting claw 7 is buckled on the rotating shaft of the rear wheel of the trolley, and the bottom of the other end of the horizontal section of the lifting claw 7 is movably connected to one end of the front shovel 9. The middle section of the front shovel 9 is movably sleeved on the rotating shaft of the front wheel of the trolley. The weight of the end of the front shovel 9 away from the lifting claw 7 is much greater than the weight of the end close to the lifting claw 7.

[0024] A lifting block 14 is provided on the side of the trolley 5 away from the front shovel 9, and the upper surface of the lifting block 14 is an inclined surface. When the front end of the front shovel 9 touches the lifting block 14, the front end of the front shovel 9 will be lifted by the lifting block 14, and the end of the front shovel 9 connected to the lifting claw 7 will be lowered accordingly, causing the lifting claw 7 to be lowered, so that the push rod 4 can no longer be stuck in the slot 8, prompting the trolley to stop running.

[0025] An anti-flip plate is provided under the front car of each group of trolleys 5, and a corresponding baffle is provided under the rear car. When the front end of the shovel 9 before the jacking block is jacked up, the anti-flip plate will be inserted under the baffle to prevent the trolley from overturning.

[0026] The action process of the present invention is as follows:

[0027] First, hang the workpiece under the suspension assembly 6 through the hook 12, start the equipment, and make the driving device drive the chain 3 to drive the push rod 4 to move continuously. When the push rod 4 touches the slot 8 on the lifting claw 7 above the trolley 5, it is stuck in the slot 8, thereby driving the trolley 5 to move. When the front car of the trolley touches the jacking block 14 of the rear car of the previous group of cars, the front end of the front shovel 9 will be lifted by the jacking block 14, and the end of the front shovel 9 connected to the lifting claw 7 will be lowered accordingly, causing the lifting claw 7 to lower, so that the push rod 4 can no longer be stuck in the slot 8, prompting the trolley to stop running.

[0028] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
