Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt processing, in particular to a loading and unloading device for an anchor bolt thread rolling machine. Background Art

[0002] Anchor bolts play a vital role in construction projects, mechanical equipment installation, and the securing of structures such as bridges, power poles, communication towers, and highway signs. The surface of anchor bolts is typically thread-rolled to facilitate connection to the structure. When thread rolling the anchor bolt rods on a thread rolling machine, workers move the rods to the machine's processing position. After processing, they are removed and placed in a collection location, where the next rod is moved for processing. This reciprocating process is repeated to complete the thread rolling of several anchor bolt rods. However, typical anchor bolt rods are typically large in diameter, long, and heavy. This repeated handling can easily lead to fatigue among workers, putting them at risk of crushing fingers or injuring their feet. Furthermore, the excessive length of the anchor bolts makes them difficult to move, making loading the thread rolling machine difficult and laborious. Utility Model Content

A first bracket 8 is provided on one side of the slow material rack 1, and the end of the first bracket 8 corresponds to the rolling station of the thread rolling machine. A plurality of support assemblies 3 and a first lifting pulley 7 are provided on the first bracket 8. Preferably, two groups of support assemblies 3 are provided, and three groups of first lifting pulleys 7 are provided. The first lifting pulleys 7 and the support assemblies 3 are cross-arranged along the length direction of the first bracket 8; the support assembly 3 is not higher than the turntable 6 and the gap between the support assembly 3 and the turntable 6 is not greater than the diameter of the anchor bolt; a second bracket 10 is provided on the side of the first bracket 8 away from the thread rolling machine, and the second bracket 10 is arranged longitudinally with the first bracket 8, and a plurality of second lifting pulleys 11 and a discharge guide plate 20 are provided on the second bracket 10, and a collecting rack 17 is provided on one side of the second bracket 10, and the upper surface of the discharge guide plate 20 is an inclined surface inclined toward the side of the collecting rack.

[0024] The anchor bolts are temporarily placed on the buffer rack 1, the material picking rack 2 is lowered to be flush with the upper surface of the buffer rack 1, and after the anchor bolts roll to the upper surface of the material picking rack 2, the material picking rack 2 is raised to be flush with the turntable 6 and the anchor bolts roll onto the turntable 6, and then roll onto the support assembly 3, and the support assembly 3 supports the anchor bolts for thread rolling on the thread rolling machine. After the thread rolling is completed, the first lifting pulley 7 rises above the support assembly 3 to support the anchor bolts on the first lifting pulley 7, and the anchor bolts slide along the arrangement direction of the first lifting pulley 7 to the second lifting pulley 11 and reach the side of the collecting rack 17, and then the second lifting pulley 11 is lowered to below the unloading guide plate 20. At this time, the anchor bolts are located on the unloading guide plate 20 and roll along the inclined upper surface of the unloading guide plate 20 to the collecting rack 17, completing the unloading and collection of the anchor bolts.
