Referring to fig. 1, a spreader mechanism 100 disclosed in at least one embodiment of the present application includes a spreader body 110, a plurality of lifting members 120, and a plurality of first driving members 130 for lifting a concrete molding module.

In some embodiments, the spreader body 110 may be comprised of two longitudinal beams and a plurality of cross beams spanning between the two longitudinal beams. The longitudinal beams and the transverse beams are fixed by welding and used for installing the hoisting piece 120 and the first driving piece 130.

All the hoisting pieces 120 are arranged opposite to each other in pairs. Specifically, all the hoists 120 are disposed opposite to each other two by two in the longitudinal direction of the hanger body 110. More specifically, all the hoists 120 are disposed opposite to each other at equal intervals in the longitudinal direction of the hanger body 110.

Further, every two opposite hoisting pieces 120 are arranged at intervals to form hoisting spaces. Each lifting piece 120 is movably arranged on the lifting tool body 110, one end of each lifting piece extends out of the lifting tool body 110 and is constructed to form a lifting end 121, and all the lifting ends 121 are constructed to be capable of cooperatively lifting the concrete forming module 500.

Specifically, in some embodiments, as shown in fig. 1, each of the lifting members 120 includes a suspension arm, the lifting end 121 can be a hook coupled to an end of the suspension arm away from the hanger body 110, and the suspension arm and the hook can be welded, assembled, or integrally formed.

During concrete to the actual application, when hoist and mount concrete forming module 500, the diapire bearing of concrete forming module 500 is on whole lifting hooks, and the lateral wall can contact with the davit, also can contactless. In a preferred embodiment, the sidewalls of the concrete forming module 500 and the boom arm contact each other to improve the stability of the spreader mechanism 100 in lifting the concrete forming module 500.

It should be noted that each size of the concrete forming module 500 is changed according to the design requirement of the product, so when the concrete forming modules 500 with different sizes are hoisted, multiple different types of the hoisting device mechanisms 100 need to be designed in a matching manner. Therefore, the lifting appliance mechanism 100 needs to be frequently replaced, the preparation time of finished products is prolonged, and the lifting cost is also increased.

To solve the above problem, in some embodiments, the spreader mechanism 100 further includes a plurality of first driving members 130 mounted on the spreader body 110, and a first driving member 130 is drivingly connected between each two oppositely disposed sling members 120. Each first driving member 130 is capable of driving the two sling members 120 connected thereto towards or away from each other.

Referring to fig. 1, in some embodiments, each first driving member 130 can drive the two hoisting members 120 connected thereto to move toward or away from each other along the transverse direction of the spreader body 110. It is to be understood that the above description is intended to be illustrative only and is not intended to be limiting.

In practical application, before the lifting tool mechanism 100 lifts the concrete forming module 500, each first driving member 130 can drive the two lifting members 120 connected with the first driving member to move away from each other until the distance between the two lifting members 120 is greater than the width of the concrete forming module 500, and all lifting ends 121 are moved to a height lower than the bottom height of the concrete forming module 500, so as to complete preassembly; when the lifting tool mechanism 100 lifts the concrete forming module 500, each first driving member 130 can drive the two lifting members 120 connected with the first driving member to approach each other, so that the lifting ends 121 of all the lifting members 120 clamp the bottom of the concrete forming module 500 to finish lifting; when the lifting tool mechanism 100 unloads the concrete forming module 500, each first driving member 130 can drive the two lifting members 120 connected with the first driving member to be away from each other, so that the lifting ends 121 of all the lifting members 120 are loosened from the concrete forming module 500, and unloading is completed. So, at concrete forming module 500 handling in-process, replace the mode of pre-buried furred ceiling through hoisting accessory 120, reduced the harm to concrete forming module 500. In addition, manual hanging nails are not needed, local structure reinforcement of a hanging point is not considered, potential safety hazards are avoided, damage of the lifting to the concrete forming module 500 is reduced, and lifting automation is convenient to achieve.

Each first driving member 130 includes a hoisting driving portion 131 and two telescopic portions 132 in transmission connection with the hoisting driving portion 131. Further, the end of each sling 120 connected to the sling body 110 is defined as a connection end 122. The connecting ends 122 of each two opposite lifting pieces 120 are respectively connected to the two telescopic parts 132. Furthermore, the hoisting driving part 131 is controlled to drive the two telescopic parts 132 to drive the hoisting member 120 connected with the two telescopic parts to perform telescopic motion relative to the hanger main body 110.

Referring to fig. 3, in some embodiments, the hoisting driving portion 131 may be a swing cylinder, the two telescopic portions 132 are respectively connected to two opposite ends of the swing cylinder in a driving manner, and the telescopic portion 132 may be a telescopic rod connected to the swing cylinder in a driving manner. The telescopic rod comprises a first rod and a second rod, the first rod is connected to the wall of the swing oil cylinder shell in a matching mode, the second rod is movably connected to the first rod, and one end of the second rod is connected with the connecting end 122 of the hoisting piece 120. Alternatively, the second rod may be pinned to the connecting end 122. The second rod can extend forwards or retract backwards relative to the first rod along the longitudinal direction of the first rod under the oil pressure driving of the swing oil cylinder so as to drive the two oppositely arranged hoisting pieces 120 to approach to or depart from each other. Thus, the lifting pieces 120 which are oppositely arranged in pairs can be close to or far away from each other, so that the concrete forming module 500 is supported or released.

It should be noted that, because the concrete forming module 500 is mainly made of building materials with large unit weight, such as concrete, etc., when the hoisting member 120 of the hoisting mechanism 100 hoists the concrete forming module 500, the dangerous situation that the hoisting member 120 hoists the concrete forming module 500 is not firm or even falls off inevitably occurs.

Therefore, in some embodiments, the spreader mechanism 100 further comprises a plurality of positioning members 140, and the plurality of positioning members 140 are disposed on the spreader body 110 at intervals along the moving path of the connecting end 122 of the sling 120.

Specifically, in some embodiments, referring to fig. 3 again, the positioning members 140 are disposed beside the telescopic portion 132 of the first driving member 130 and are disposed on the hanger body 110 at intervals along the moving path of the connecting end 122 of the hanger 120. In a preferred embodiment, a plurality of positioning members 140 are provided on the hanger body 110 at equal intervals along the moving path of the connecting end 122 of the sling 120.

Further, the hoisting driving part 131 can drive the connecting end 122 of the hoisting member 120 to be clamped to one positioning member 140. Specifically, the hoisting driving portion 131 drives the telescopic portion 132 to perform telescopic motion, and simultaneously drives the connecting end 122 of the hoisting member 120 coupled to the telescopic portion 132 to perform reciprocating motion. After the hoisting end 121 of the hoisting member 120 hoists the concrete forming module 500, the position of the connecting end 122 of the hoisting member 120 is adjusted until the distance between the connecting end 122 of the hoisting member 120 opposite to the position is equal to the width of the concrete forming module 500, and then the connecting end 122 of the hoisting member 120 is driven to be clamped into a positioning member 140 nearby. So, realize that the distance between the link 122 of relative hoist and mount piece 120 is stable, avoid taking place hoist and mount concrete forming module 500 insecure at the hoist and mount in-process, the danger that drops even.

Alternatively, the positioning members 140 may be positioning slots provided on the hanger body 110 at intervals along the moving path of the connecting end 122 of the hanger 120.
