as shown in connection with fig. 1 to 3, the present invention provides a double boom hanger. The beam 1 is a square hollow cylinder with two open ends, and the upper and lower opposite surfaces of the beam 1 are provided with sliding grooves 11. The two carriages 2 are symmetrically arranged on both sides of the cross beam 1. A boom 10 is hinged to the outer end of each carriage 2.
And in combination with the figure 4, the sliding frame 2 is of a T-shaped hollow structure, and the inner end close to the cross beam 1 is of an open structure. The inner end of the carriage 2 is slidably inserted into the cross beam 1, the outer end of the carriage 2 extends out of the cross beam 1. An outer limiting block 21 is fixed on the upper side surface and the lower side surface of the outer end of the sliding frame 2. The outer stopper 21 is engaged with an end face of the cross member 1 for restricting the length of insertion of the carriage 2 into the cross member 1. An inner limiting block 22 is fixed on the upper side and the lower side of the inner end of the sliding frame 2. An inner stopper 22 is limited in the chute 11 for limiting the length of the carriage 2 extending out of the cross beam 1. The carriage 2 can slide along the cross beam 1 within a certain range by providing the outer stopper 21 and the inner stopper 22.
Referring again to fig. 5, a pulley assembly 3 is mounted between each carriage 2 and the cross beam 1, the pulley assembly 3 comprising an outer pulley set 31 and an inner pulley set 32:
The outer pulley group 31 comprises a vertical row of outer pulleys 311 arranged in the carriage 2 near the outer end, and the rotating shafts of the outer pulleys 311 are fixed on the two side walls of the carriage 2. An outer rope baffle 312 is provided at both sides of the outer pulley 311. The outer rope baffle 312 is arranged on the rotating shaft of the outer pulley 311 in a penetrating way and is used for preventing the pull rope 7 from falling off;
the inner wheel set 32 comprises a pair of inner rope baffle plates 322, and the upper ends and the lower ends of the two inner rope baffle plates 322 are fixedly connected through U-shaped ribs 324. A vertical row of inner pulleys 321 is arranged between the two inner rope baffle plates 322, and the number of the inner pulleys 321 is one less than that of the outer pulleys 311. The two ends of the inner rope baffle 322 are respectively fixed with a sliding block 323, and the sliding blocks 323 are in sliding connection with the sliding grooves 11 on the corresponding sides, so that the inner wheel set 32 can slide along the sliding grooves 11.
As shown in fig. 4 and 5, the two inner wheel sets 32 are connected by an elastic assembly 4, and the elastic assembly 4 provides a pulling force for the two inner wheel sets 32 to approach each other. The elastic assembly 4 comprises a vertical row of elastic pull rods 41 parallel to each other, and flange plates 42 are fixed at two ends of the elastic pull rods 41, and the flange plates 42 are fixedly connected to the inner rope baffle plates 322 of the inner wheel group 32 at the corresponding side through bolts.
As shown in fig. 2 to 4, a rope passing hole 12 through which the pull rope 7 passes is formed at the lower side of the outer end of the cross beam 1, and the rope passing hole 12 is vertically opposite to the outer wheel group 31 in the cross beam 1. The upper side of the cross beam 1 is connected with a hollow bolt 8 through threads. One end of the pull rope 7 is fixed with the lifting hook 6, and the other end of the pull rope 7 repeatedly bypasses the outer wheel group 31 and the inner wheel group 32 on the corresponding sides and then penetrates into the hollow bolt 8. The stay cord 7 and the hollow bolt 8 can be fixed in a knotting mode. When the device is used, under the action of the pulley assembly 3 and the elastic assembly 4, the hooks 6 on two sides can be directly pulled to the suspension points of the frame, and the elastic assembly 4 can always ensure that the pull rope 7 is in a generally tight state.
As shown in connection with fig. 5 and 6, the locking assembly 5 is used to lock the position of the two inner wheel sets 32. The locking assembly 5 comprises a first rack 51 and a second rack 52 parallel to each other, the teeth of the first rack 51 and the teeth of the second rack 52 being arranged in pairs with a gap between each other. One end of the first rack 51 is fixed to the U-shaped rib 324 of the first inner wheel set 32, and the other end slides on the surface of the U-shaped rib 324 of the second inner wheel set 32. One end of the second rack 52 is fixed to the U-shaped rib 324 of the second inner wheel set 32, and the other end slides against the surface of the U-shaped rib 324 of the first inner wheel set 32. By inserting the lock piece 53 between the teeth of the first rack 51 and the teeth of the second rack 52, the first rack 51 and the second rack 52 can be restrained from moving relative to each other.
Referring again to fig. 7, in this embodiment, the locking piece 53 includes a strut 531, and vertical spindle bars 532 are fixed on two sides of the strut 531, and the spindle bars 532 may be inserted between the teeth of the first rack 51 and the teeth of the second rack 52. Two pairs of positioning blocks 54 are fixed on the upper side of the cross beam 1, two ends of a supporting rod 531 are respectively placed between each pair of positioning blocks 54, and the position of the supporting rod 531 is limited through the positioning blocks 54, so that the position limitation of the two inner wheel groups 32 relative to the cross beam 1 is realized. An elastic band 55 is connected between each pair of positioning blocks 54, and the elastic band 55 is pressed on the end of the supporting rod 531 to prevent the supporting rod 531 from being separated. In addition, when the inner wheel set 32 is unlocked, the pressure of the elastic belt 55 can be overcome, the support rod 531 is pulled out upwards and rotated 180 degrees, the support rod 531 can still be limited between the positioning blocks 54 while the inner wheel set 32 is unlocked, the use is convenient, and the loss of the support rod 531 can be prevented.
Embodiment two:
As shown in fig. 8, the present invention further provides a frame conveying line based on the first embodiment. The conveying line comprises a circularly moving transmission chain 9, and the upper ends of suspenders 10 at the two ends of the hanger are hinged on the transmission chain 9. In the idle state, the distance between the upper ends of the two suspenders 10 is slightly larger than the distance between the lower ends of the two suspenders 10, so that the carriage 2 is guaranteed to be in a retractable and extendable state of the cross beam 1, and the pull rope 7 can be pulled out more easily.
When in use, the frame is arranged on the feeding table, and the hanger moves to the upper part of the feeding table along with the transmission chain 9; firstly, the left lifting hook 6 is pulled to a frame suspension point and is connected with the frame, and at the moment, the right lifting hook 6 correspondingly ascends under the action of the pull rope 7 and the two groups of pulley assemblies 3; then, the lifting hook 6 on the right side is dragged to another suspension point of the frame, under the dragging action, the pulling force of the elastic component 4 is overcome, the outer wheel group 31 and the inner wheel group 32 in the two pulley components 3 are correspondingly close, and the lifting hook 6 on the right side can be smoothly pulled out; after the lifting hook 6 on the right side is connected with the frame, the locking block 53 is inserted between the teeth of the first rack 51 and the teeth of the second rack 52, and the two groups of pulley assemblies 3 are locked to ensure that the position of the lifting hook 6 is approximately unchanged; finally, as the drive chain 9 is progressively lifted, the hanger and carriage are transported to a predetermined working station.
The invention utilizes two groups of pulley assemblies to allow the lifting hooks and the pull ropes on two sides to flexibly extend, thereby being capable of accurately adjusting the lifting hooks to the ideal suspension position of the frame according to actual needs, greatly facilitating the lifting operation of the frame and being suitable for frames with different specifications and placement states. The elastic component integrated in the middle can automatically adjust the tension of the pull ropes at two sides, and the pulley component is stabilized through the locking component, so that the height of the frame in the lifting process is ensured, and various processing operations can be smoothly carried out.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
