Abstract
The utility model relates to a device for preventing the hook head of a crane from rotating. A circular hole is formed in the center of the device; a retaining plate of a key slot is arranged on the circular hole; the circular hole is in mutual fit of sleeve joint with the hook head; and the retaining plate is linear-type in the width direction, and is in contact fit with a hook head pulling plate of the crane. The device has the advantages that the structure is simple, and the device can be mounted on the crane when the hook head of the crane is required to be fixed according to the requirements for production, and dismounted when the hook bill of the crane is required to rotate, thereby ensuring convenient use and effectively improving the working efficiency.
Description
Technical field
The utility model relates to a kind of crane gib head anti-rotation device.
Background technology
Suspension hook is one of most important parts of crane, is a kind of load-engaging device of widespread use on the crane.In lifting operation, suspension hook and pulley combination together, suspension hook can rotate relative to pulley, but in production reality, some crane is being undertaken the dual role of Product transport and overhaul of the equipments.In daily production reality, use the horizontal roll anchor clamps that ground-surface roll bending is transported, clamp is fixed with volume hole direction relatively, and the crane hook-bill is fixed, to finish handling coil of strip task.But hook-bill needs rotation again in maintenance several times in every month, so that the lifted weight thing is placed on assigned address on request.The crane hook-bill has a bolt of rear end plate when dispatching from the factory, and in the practical application, when especially needing for a long time fixedly, poor practicability can not well satisfy the surface production needs, does not have good result.
Summary of the invention
The utility model has overcome deficiency of the prior art, provide a kind of simple in structure, the crane gib head anti-rotation device of easy installation and removal, this device can be according to the requirement of producing at needs crane gib head fixedly the time, effectively control crane gib head rotation, the needs of satisfied production and maintenance.
In order to address the above problem, the utility model by the following technical solutions:
A kind of crane gib head anti-rotation device, this device are that a center is provided with the adapter plate that circular hole and circular hole are provided with keyway, and described circular hole socket-connects with hook bolt and cooperates.
Described adapter plate is a linear pattern at Width, and cooperation contacts with crane gib head arm-tie.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, the fixing or rotation of suspension hook is controlled in easy installation and removal effectively, has improved production efficiency.
Description of drawings

Fig. 2 is a mounting structure scheme drawing of the present utility model
Among the figure: 1-adapter plate 2-crane gib head arm-tie 3-keyway 4-circular hole 5-hook bolt
The specific embodiment
See Fig. 1, Fig. 2, a kind of crane gib head anti-rotation device, this device are that a center is provided with the adapter plate 1 that the certain thickness steel plate of employing that circular hole 4 and circular hole 4 be provided with keyway 3 is made, and circular hole 4 socket-connects with hook bolt 5 and cooperates.
When crane gib head fixedly the time, at first on crane hook bolt 5, weld key, circular hole 4 structures of this device are socketed in the outside of hook bolt 5, the key of welding matches fixing with the keyway 3 of adapter plate 1 on the hook bolt 5.Because the linear pattern at adapter plate 1 two ends contacts with gib head arm-tie 2, can prevent mutual play.
Claims (2)
1, a kind of crane gib head anti-rotation device is characterized in that, this device is that a center is provided with circular hole (4) and circular hole (be provided with the adapter plate (1) of keyway (3), described circular hole (4) socket-connects with hook bolt (5) and cooperates.
2, crane gib head anti-rotation device according to claim 1 is characterized in that, described adapter plate (1) is a linear pattern in the degree direction, and cooperation contacts with crane gib head arm-tie (2).
