Description

TECHNICAL FIELD

[0001] The utility model relates to a hook device technical field, concretely relates to a novel anti-unhooking device of hook. BACKGROUND

[0002] The anti-unhooking device of hook used in the water flushing slag area is composed of spring and lock sheet. Because of the large steam on site, the spring and lock sheet are corroded very seriously, the lock sheet is thinned and deformed, and the spring loses elasticity. During hoisting operation, there is a very big security risk. Moreover, the spring of the new anti-unhooking device has very big elasticity, and it is very laborious and inconvenient to operate during use. CONTENT OF THE UTILITY MODEL

[0003] The utility model discloses a novel anti-unhooking device of hook, which is convenient to operate and saves time and effort.

[0004] In order to solve the problems in the background art, the utility model adopts the following technical scheme: including special-shaped support plate, the special-shaped support plate has two, the two special-shaped support plates are connected with support block through fixed bolt in the middle, the support block one end is fixedly connected with hook, the hook is equipped with support rod, the support rod top is equipped with anti-unhooking device, the anti-unhooking device includes cross bar, rotating ring, L type clamp and counterweight, the cross bar is vertically equipped on the support rod, the cross bar both ends are slidably connected with rotating ring respectively, two rotating rings are respectively welded with the inner angle of L type clamp, the L type clamp one end is connected with hook, and the L type clamp other end is installed counterweight.

[0005] The both ends of the cross bar are respectively equipped with recess, and the recess is respectively equipped with rotating ring, and the rotating ring is limited in the recess.

[0006] The L type clamp is rotated on the cross bar through the rotating ring and is rotated 0-360 degrees.

[0007] The number of counterweights is several, and the grammage is the same or different, and the counterweights are suspended or welded from top to bottom.

[0008] The utility model has the advantages of convenient operation, time and effort saving, steam corrosion resistance, convenient production and low cost. DRAWINGS

[0009] Figure 1 It is the structure schematic diagram of the utility model. CONCRETE IMPLEMENTING METHOD

[0010] Referring to each Figure 1The utility model discloses a specific adoption follows implementation mode: including the special-shaped support board 1, the special-shaped support board 1 has two, and the two special-shaped support boards 1 are connected support block 3 through fixed bolt 2 in the middle, and support block 3 one end fixed connection lifting hook 6 is equipped with support rod on lifting hook 6, and support rod top is equipped with anti -unhooking device, and anti -unhooking device includes crosspiece 4, rotating ring 8, L type clamp piece 5 and counterweight 7, crosspiece 4 is vertically equipped on support rod, and crosspiece 4 both ends are slidably connected rotating ring 8 respectively, and two rotating ring 8 are respectively welded with the interior angle of L type clamp piece 5, and L type clamp piece 5 one end is connected with lifting hook 6, and L type clamp piece 5 other end installs counterweight 7. The both ends of crosspiece 4 are equipped with recess respectively, and rotating ring 8 is arranged in recess respectively, and rotating ring 8 is limited in recess. L type clamp piece 5 is rotated on crosspiece 4 through rotating ring 8 and is 0~360 degrees. The number of counterweight 7 is several, and the grammage is same or different, and is hung or welded from top to bottom in turn.

[0011] The anti-unhooking device of the hook used in the water slagging area is composed of a spring and a locking plate. Because of the steam on site, the spring and the locking plate are severely corroded, the locking plate is thinned and deformed, and the spring loses elasticity. During hoisting operation, there is a very big safety hazard. Moreover, the spring force of the existing anti-unhooking device is very large, and it is very laborious and inconvenient to operate during use.

[0012] The new anti-unhooking device of the hook is a self-made anti-unhooking device, and the end of the locking plate is replaced by a counterweight. One or several counterweight blocks 7 are installed. The grammage of the counterweight blocks 7 can be the same or different, and the weight of the counterweight blocks 7 can be added according to actual needs.

[0013] By rotating the L-shaped clamp piece 5, the L-shaped clamp piece 5 is rotated on the crosspiece 4, so that one end of the L-shaped clamp piece 5 is connected with the inner side of the lifting hook 5, and the counterweight block 7 at the other end of the L-shaped clamp piece 5 plays a role of pulling down, that is, generates a downward pulling force, which will not cause the end connected with the lifting hook 6 to rebound.

[0014] In summary, the new anti-unhooking device of the hook is convenient to operate, saves time and effort, resistant to steam corrosion, easy to manufacture and low in cost.
