Abstract
The invention discloses a hoisting device with a ratchet device. A rope winding wheel (3) is installed on a floorstand (1) through a rotating shaft (2), a hoisting rope (4) is wound on the rope winding wheel (3), a ratchet (5) is fixed to the rope winding wheel (3), a supporting rod (7) is installed on the floorstand (1), one end of a connecting rod (6) is movably connected with the supporting rod (7), the other end of the connecting rod (6) is provided with a pawl (6-1), an air cylinder (8) is installed on the floorstand (1), and one end of a piston rod of the air cylinder (8) is connected with the connecting rod (6) in a transmission mode. The hoisting device with the ratchet device has the advantages of being simple in structure, low in manufacturing cost and convenient to use.
Description
?
Technical field
The present invention relates to chain sling field, be specifically related to a kind of novel chain sling.
Background technology
In building coating work progress; Often coating need to be winched to high level and carry out coating application.The complex structure that existing chain sling has, manufacturing cost is high, and some uses are convenient not.
Summary of the invention
Object of the present invention is exactly for the above-mentioned deficiency of existing chain sling, and provides
a kind of chain sling with escapement.
The present invention is comprised of stand, rotating shaft, bull wheel, load rope, pole, cylinder and escapement, escapement is comprised of ratchet and connecting rod, bull wheel is arranged in stand by rotating shaft, load rope is on bull wheel, and ratchet is fixed on bull wheel, and pole is arranged in stand, connecting rod one end and pole are movably connected, the other end of connecting rod is provided with ratchet, and cylinder is arranged in stand, and piston rod one end of cylinder is connected with link transmission.
Advantage of the present invention is: it is simple in structure, and low cost of manufacture is easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is comprised of stand 1, rotating shaft 2, bull wheel 3, load rope 4, pole 7, cylinder 8 and escapement, escapement is comprised of ratchet 5 and connecting rod 6, and bull wheel 3 is arranged in stand 1 by rotating shaft 2, and load rope 4 is on bull wheel 3, ratchet 5 is fixed on bull wheel 3, pole 7 is arranged in stand 1, and connecting rod 6 one end and pole 7 are movably connected, and the other end of connecting rod 6 is provided with ratchet 6-1, cylinder 8 is arranged in stand 1, and piston rod one end of cylinder 8 is connected with connecting rod 6 transmissions.
Mode of operation: be fixed in the roof portion of hugging during use, rotation bull wheel 3 is crossed load rope 4 can lift by crane article, now, ratchet 6-1 is meshed with the tooth on ratchet 5, bull wheel 3 can only unidirectional rotation, can not reverse, and the article that therefore lifting by crane can only rise, can not decline midway, can guarantee to lift by crane safety of goods.
When the article of lifting are while hanging the position of needs, take off article, start cylinder 8, the piston rod of cylinder 8 stretches out, and makes the tooth disengaging on ratchet 6-1 and ratchet 5, and now bull wheel 3 is can be positive and negative two-way freely rotates, and load rope 4 is transferred to ground.When cylinder 8 return, drive ratchet 6-1 to reset, ratchet 6-1 is meshed with the tooth on ratchet 5, and bull wheel 3 can only unidirectional rotation, can not reverse.Can be again for lifting by crane article.
