Referring to fig. 2 and 3, the utility model provides an automatic opening and closing rolling type pulley, which comprises a frame 1, pulleys 2 arranged on two sides of the frame 1 and used for sliding connection with a vertical rail E, two connecting pieces 3 symmetrically arranged on the top of the frame 1 and used for connecting with a sling G, and at least one hook 4;

the hook 4 comprises a swing rod 4.1 with the upper end pivotally connected with the frame 1 and a hook head 4.2 arranged at the lower end of the swing rod 4.1.

During operation, the hook head 4.2 is located below the hook head 90.1 of the girder 90, then the pulley is lifted by the suspension cable G, so that the girder 90 is lifted, and finally the pulley moves horizontally along with the vertical rail E to transfer the girder 90. The pulley has the following advantages:

2. the pulley moves along the vertical guide rail, cannot swing in the hoisting process and has good stability.

Further, as shown in fig. 2, the frame 1 includes a frame 1.1, a horizontal sliding chute 1.2 disposed at the upper portion of the frame, a horizontal guide rail 1.3 disposed at the lower portion of the frame, and two sliding seats 1.4 slidably connected to the horizontal sliding chute 1.2 and the horizontal guide rail 1.3; the three hooks 4 are arranged, one of the three hooks is arranged in the middle of the frame 1 and is connected with the frame 1.1 (namely, the swing rod 4.1 of the hook is connected with the frame 1.1 through a pivot), and the other two hooks are symmetrically arranged on two sides of the middle hook and are respectively connected with the two sliding seats 1.4 (namely, the swing rod 4.1 of the hook is connected with the sliding seats 1.4 through a pivot); the frame 1 is also provided with a driving mechanism 5 for driving the two sliding seats 1.4 to synchronously move in opposite directions.

Three hangers 4 are arranged to hoist three girders 90 simultaneously, so that the production efficiency is improved, the driving mechanism 5 is arranged to drive the two sliding seats 1.4 to move synchronously and reversely, and the intervals between the three hangers 4 can be adjusted to adapt to the size of the intervals between the girders. The upper end of the sliding seat 1.4 is provided with a plurality of rollers, the rollers extend into the horizontal sliding groove 1.2, part of the rollers are abutted against one side of the horizontal sliding groove 1.2, and part of the rollers are abutted against the other side of the horizontal sliding groove 1.2, so that front and back limiting is realized; the lower end of the sliding seat 1.4 is provided with a plurality of rollers, and the rollers comprise rollers which are respectively propped against three side surfaces of the horizontal guide rail 1.3 so as to realize front and back limiting and upper and lower limiting.

In some embodiments, see fig. 2, the driving mechanism 5 includes two coaxially disposed horizontal screws 5.1, a coupling 5.2 connecting the two horizontal screws, and a motor 5.3 for driving the horizontal screws 5.1 to rotate; the threads of the two horizontal lead screws 5.1 are reversed; the two sliding seats 1.4 are respectively in threaded transmission connection with two horizontal lead screws 5.1.

When the motor 5.3 rotates, one of the horizontal screw rods 5.1 is driven to rotate, and under the action of the coupler 5.2, the other horizontal screw rod 5.1 synchronously rotates, so that the two sliding seats 1.4 synchronously move towards or away from each other, and the hooks 4 are always at equal intervals. Wherein, a screw nut 1.4a is arranged on the sliding seat 1.4, and a horizontal screw 5.1 penetrates through the screw nut 1.4a, thereby realizing the thread transmission connection, as shown in fig. 3. However, the form of the screw drive connection is not limited to this, and for example, a threaded hole adapted to the horizontal lead screw 5.1 may be directly formed in the slide 1.4, and the horizontal lead screw 5.1 may be inserted through the threaded hole.

In the present embodiment, the motor 5.3 drives the horizontal lead screw 5.1 to rotate through the chain 5.4, as shown in fig. 2. Wherein, a chain wheel is arranged on one horizontal screw rod 5.1, and a chain 5.4 is meshed with the chain wheel.

In some preferred embodiments, see fig. 2, the lower end of each rocker 4.1 is provided with a plurality of hooks 4.2, the plurality of hooks 4.2 being evenly distributed along a straight line in the horizontal direction. The end part of each girder 90 is hooked by a plurality of hook heads 4.2 for hoisting, and the hoisting process is more stable.

In some preferred embodiments, see fig. 3, the hook head 4.2 is plate-shaped, and a V-shaped opening 4.2a is opened at the upper side of one end of the hook head, which is far away from the swing link 4.1, and one side of the V-shaped opening, which is far away from the swing link 4.1, extends to a position intersecting with the end surface of the hook head 4.2 so as to form a pointed hook part 4.2b together with the end surface of the hook head. Because the force of the girder 90 on the hook head 4.2 is vertically downward and is positioned in the vertical plane where the plate-shaped hook head is positioned in the hoisting process, the plate-shaped hook head has stronger bearing capacity compared with a common sharp hook.

In some embodiments, see fig. 3, two sets of pulleys 2 are respectively arranged on two sides of the frame 1, and the two sets of pulleys are distributed up and down; each group comprises two pulleys 2 arranged at intervals along the horizontal direction, and a vertical track E passes through between the two pulleys 2. Namely, the two sides of the vertical track E are clamped by the two pulleys 2 on one side, so that the front and back limiting is realized, and the frame 1 can be prevented from being separated from the vertical track E.

Further, as shown in fig. 2 and 3, guide wheels 6 are further arranged on two sides of the frame 1, the guide wheels 6 are slidably connected with the vertical rail E, and the axial direction of the guide wheels 6 is perpendicular to the axial direction of the pulley 2. The guide wheels 6 on the two sides are respectively abutted against the two vertical tracks E, so that the left and right direction limitation is realized, and the frame 1 can be prevented from swinging and separating from the vertical tracks E.

Referring to fig. 1, the present invention further provides a crane, which includes two symmetrically disposed lifting devices (the portion shown in fig. 1); each lifting device comprises a horizontal track A, a traveling trolley B arranged on the horizontal track, a winding shaft C and a corresponding winding motor D which are arranged on the traveling trolley, two vertical tracks E which are fixedly connected with the traveling trolley B and extend downwards, and a pulley F which is arranged on the two vertical tracks E in a sliding manner; the pulley F is the automatic opening and closing rolling pulley; the winding shaft C is connected with the connecting piece 3 of the pulley F through a sling G.

When the trolley works, the two ends of the girder 90 are hooked by the pulleys F respectively, then the pulleys F are lifted under the action of the winding shaft C and the winding motor D, and finally the horizontal movement of the girder 90 is realized under the drive of the travelling trolley B. When the inclined water dripping is needed, the lifting heights of the two pulleys F on the two sides of the crane to the two ends of the girder 90 are different, and the swing rods 4.1 of the hooks 4 can automatically swing relative to the frame 1, so that the girder 90 can be inclined without unhooking, and the inclined water dripping can be conveniently realized.

In some preferred embodiments, one end of the take-up reel C, see fig. 1, is provided with a rotary encoder H. And the rotating angle of the winding shaft C is measured in real time through the rotary encoder H, so that the upper position and the lower position of the pulley F are monitored.

From the above, the automatic opening and closing rolling type tackle and the crane have the following advantages:

In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
