Description

Technical Field

[0001] The present invention relates to the technical field related to hoisting equipment, and in particular to hoisting equipment for steel structure construction. Background Art

[0002] Hoisting is a general term for the installation and positioning of equipment by cranes or lifting mechanisms; during the inspection or maintenance process, various lifting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position. We often encounter equipment loading, transportation, and installation work, which are often carried out by lifting with a lever or mechanical lifting. The use of lifting equipment is also indispensable in the construction of steel structures.

[0003] A Chinese patent with authorization announcement number CN115676628A discloses a hoisting device for steel structure construction. The steel structure is placed on top of an adjusting pallet and pressed on an adjusting wheel. A weighing mechanism then detects the weight difference between the two ends of the adjusting pallet. The operation of the adjusting wheel is controlled by the detection result. The adjusting wheel drives the steel structure to move so that the center of gravity of the steel structure coincides with the center of the adjusting pallet. After coincidence, there is no weight difference between the two ends of the adjusting pallet, and the hoisting center can be automatically found, thereby achieving high hoisting efficiency.

[0004] However, in the process of hoisting the steel structure, the existing steel structure hoisting equipment usually uses chains to tie the steel structure and uses the hooks in the hoisting equipment to hook and lift it. However, the process of manually arranging the chains to bind the steel structure is complicated, and the chains may get entangled, affecting the lifting efficiency of the steel structure. In addition, the process of tying the chains to bind the steel structure is prone to shaking when the steel structure is lifted, resulting in unstable lifting of the steel structure, which poses certain safety hazards.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1 to 9 , the present invention provides a technical solution: A hoisting device for steel structure construction includes a support plate 1, a connecting plate 2 is rotatably provided at the upper end of the support plate 1, a hanger 3 connected to a hook of a crane is provided above the connecting plate 2, a protective device 4 for fixing the hanger 3 is provided inside the connecting plate 2, a group of limit plates 7 are slidably installed at the bottom of the support plate 1, a binding device 5 for fixing a steel plate is provided at the bottom of the limit plate 7, and an anti-falling device 6 is provided on the side wall of the limit plate 7.

[0019] Specifically, Figure 1-2 As shown, the binding device 5 includes a motor 51, a power output shaft of the motor 51 is fixedly mounted with a winding drum 57, an outer wall of the winding drum 57 is wrapped with an iron chain 52, one end of the iron chain 52 is fixedly mounted with a buckle plate 53, and one end of the limiting plate 7 is fixedly mounted with a suspension hook 54 matching the buckle plate 53.

[0020] By adopting the above technical solution, the support plate 1 is used to support the connecting plate 2, and the hanger 3 can be conveniently connected to the hook at the output end of the crane, so as to realize the lifting of the steel structure; the motor 51 is a servo motor in the prior art, which can make the output end of the motor 51 rotate at a certain frequency in different directions; by setting a set of slidable limit plates 7 at the bottom of the support plate 1, the motor 51 is used to drive the winding drum 57 to rotate, so that the winding drum 57 controls the contraction and release of the iron chain 52, and then the buckle plate 53 is connected to the hanging hook 54, so as to realize the binding process of the steel structure, change the traditional way of manually arranging the chain, so that the chains will not be entangled and disordered, and improve the lifting efficiency of the steel structure. Among them, the anti-falling device 6 can realize the fixation of the iron chain 52, so that the iron chain 52 and the steel structure are firmly fixed. The protective device 4 can make the output end of the crane and the hanger 3 firmly fixed, and it is not easy to be unhooked.

[0021] Specifically, Figure 1-2 As shown, a groove 55 is formed on the upper surface of one end of the limit plate 7, and the motor 51 is fixedly installed in the groove 55. A protective shell 56 is fixedly installed on the upper surface of the limit plate 7 above the winding drum 57. One end of the iron chain 52 is fixedly installed on the outer wall of the winding drum 57, and the end of the iron chain 52 away from the winding drum 57 passes through the limit plate 7 and extends to the bottom of the limit plate 7.

[0022] By adopting the above technical solution, the groove 55 is used to store the motor 51, and also provides a space for the winding drum 57 to retract the iron chain 52; the protective shell 56 can protect the winding drum 57, and the protective shell 56 is fixedly connected to the limit plate 7 by screws, which can facilitate the later maintenance of the winding drum 57. When the steel plate needs to be lifted, it is only necessary to start the motor 51, so that the motor 51 drives the winding drum 57 to rotate, control the tightness of the iron chain 52, and then pull one end of the iron chain 52 to make the buckling plate 53 buckle with the hanging hook 54, and then use the motor 51 to rotate the winding drum 57 to tighten the iron chain 52, so that the buckling plate 53 and the hanging hook 54 are firmly fixed, so that the iron chain 52 can be firmly fixed to the steel structure. When it is necessary to detach the buckling plate 53 from the hanging hook 54, it is only necessary to rotate the motor 51, so that the motor 51 drives the winding drum 57 to rotate, so as to facilitate the detachment of the buckling plate 53 from the hanging hook 54, and realize the detachment of the iron chain 52, so as to facilitate the removal of the steel plate.

[0023] Specifically, Figure 1-6 As shown, the anti-falling device 6 includes a slide groove 63, which is opened on one end surface of the limiting plate 7. A slider 61 is slidably installed inside the slide groove 63. The slider 61 is L-shaped, and the end of the slider 61 away from the slide groove 63 extends to the bottom of the limiting plate 7.

[0024] By adopting the above technical solution, the slide groove 63 provides a sliding space for the slider 61. The L-shaped slider 61 can extend the main part of the slider 61 to the bottom of the limiting plate 7. The slider 61 is located at one end of the slide groove 63 and is T-shaped, so that the slider 61 will not fall off when sliding inside the slide groove 63.

[0025] Specifically, Figure 1-6 As shown, a threaded rod 64 is rotatably installed inside the slide groove 63, and a spiral transmission is performed between the threaded rod 64 and the slider 61. One end of the threaded rod 64 extends to the outside of the limit plate 7, and a group of limit rods 65 are fixedly installed on the outer wall of the slider 61. The two limit rods 65 are symmetrical about the transverse center axis of the slider 61, and the limit rods 65 are T-shaped.

[0026] By adopting the above technical scheme, the T-shaped threaded rod 64 can be convenient for holding, and the T-shaped limiting rod 65 can limit the iron chain 52. When the threaded rod 64 rotates, due to the spiral transmission between the threaded rod 64 and the slider 61, the threaded rod 64 will cause the slider 61 to produce axial movement and a large axial thrust. Therefore, the threaded rod 64 can make the slider 61 slide inside the slide groove 63, so that the slider 61 can be displaced. In addition, the outer wall of the limiting plate 7 located at the bottom of the winding drum 57 is fixedly installed with a baffle 62, and the end of the limiting rod 65 away from the slider 61 passes through the baffle 62, and the baffle 62 is parallel to the slider 61. When the iron chain 52 needs to be fixed, it is only necessary to rotate the threaded rod 64 so that the threaded rod 64 drives the slider 61 to slide inside the slide groove 63, so that the distance between the slider 61 and the baffle 62 is shortened, thereby squeezing the iron chain 52 so that the iron chain 52 will not fall off, and the chain can be fixed during work, changing the traditional way of manually tying and binding the chain, so that the steel structure can remain stable during the lifting process and avoid the occurrence of safety hazards.

[0027] Specifically, Figure 1-6 As shown, a connecting groove is provided at the bottom of the support plate 1, and a double-headed screw 8 is rotatably installed inside the connecting groove. One end of the double-headed screw 8 extends to the outside of the support plate 1, and the outer wall of the double-headed screw 8 is threadedly connected with a group of connecting blocks 9. The connecting blocks 9 are T-shaped, and the bottom of the connecting blocks 9 is fixedly connected to the upper surface of the limit plate 7.

[0028] By adopting the above technical solution, the connecting groove provides a sliding space for the connecting block 9, and the T-shaped connecting block 9 can prevent it from detaching when sliding inside the connecting groove. When the double-headed screw 8 is rotated, the double-headed screw 8 will drive the connecting block 9 to slide inside the connecting groove, and the distance between the two limit plates 7 can be adjusted.

[0029] Specifically, Figure 1-9 As shown, the protection device 4 includes a fixing rod 46, the connecting plate 2 is in a U shape, the fixing rod 46 has two fixing rods 46 and is symmetrically mounted on the inner wall of the U-shaped opening end of the connecting plate 2, and the hanging member 3 is fixedly mounted at the center of the U-shaped opening end of the connecting plate 2. A transmission plate 44 is rotatably mounted on the outer side wall of the fixing rod 46, and one end of the transmission plate 44 close to each other is rotatably connected to the two ends of the hanging member 3, and the transmission plate 44 is in an arc shape, and a buckle plate 41 is rotatably mounted on one end of one of the transmission plates 44, and a buckle plate 43 is rotatably mounted on one end of the other transmission plate 44.

[0030] By adopting the above technical scheme, the fixing rod 46 acts as a fulcrum to facilitate the rotation of the transmission plate 44. A torsion spring is fixed to the outer wall of the fixing rod 46. The end of the torsion spring away from the fixing rod 46 is fixedly connected to the outer wall of the transmission plate 44. The elastic force provided by the torsion spring can keep the transmission plate 44 in the tendency to reset. The snap plate 41 is U-shaped, and the inner wall of the U-shaped opening end of the snap plate 41 is fixedly installed with a sliding block 48. The upper surface of one end of the snap plate 41 is fixedly installed with a first extrusion plate 42. The outer wall of the buckle plate 43 is provided with a group of symmetrical buckle grooves 47. The sliding block 48 matches the buckle groove 47. The buckle groove 47 provides a sliding space for the sliding block 48, so that the snap plate 41 will not be detached when the outer wall of the buckle plate 43 slides.

[0031] Specifically, Figure 1-9 As shown, a second extrusion plate 45 is fixedly mounted on the upper surface of one end of the buckle plate 43 , and the first extrusion plate 42 is parallel to the second extrusion plate 45 .

[0032] By adopting the above technical solution, since the first extrusion plate 42 is parallel to the second extrusion plate 45, when the hook at the output end of the crane is connected to the hanger 3, the hanger 3 will drive the two transmission plates 44 to rotate around the fixed rod 46, and the two transmission plates 44 will drive the snap plate 41 to slide around the outer wall of the buckle plate 43, so that the two first extrusion plates 42 and the second extrusion plates 45 are close to each other to squeeze the rope at the output end of the crane, thereby squeezing and fixing the rope at the output end of the crane, and limiting the hook of the crane, thereby preventing the crane from being unhooked during the process of lifting and lowering the steel structure, avoiding the occurrence of safety hazards.

[0033] Working principle: When the steel plate needs to be lifted, it is only necessary to start the motor 51, so that the motor 51 drives the winding drum 57 to rotate, control the tightness of the iron chain 52, and then pull one end of the iron chain 52 to make the buckle plate 53 buckle with the hanging hook 54, and then use the motor 51 to rotate the winding drum 57 to tighten the iron chain 52, so that the buckle plate 53 and the hanging hook 54 are firmly fixed, so that the iron chain 52 can be firmly fixed to the steel structure. When it is necessary to release the buckle plate 53 from the hanging hook 54, it is only necessary to rotate the motor 51 so that the motor 51 drives the winding drum 57 to rotate, so as to facilitate The buckling plate 53 is disengaged from the hanging hook 54 to achieve the disengagement of the iron chain 52, thereby facilitating the removal of the steel plate. When the iron chain 52 needs to be fixed, it is only necessary to rotate the threaded rod 64 so that the threaded rod 64 drives the slider 61 to slide inside the slide groove 63, so that the distance between the slider 61 and the baffle 62 is shortened, thereby squeezing the iron chain 52 so that the iron chain 52 will not be disengaged, and the chain can be fixed during work, changing the traditional way of manually tying and binding the chain, so that the steel structure can remain stable during the lifting process and avoid the occurrence of safety hazards. Finally, when the hook at the output end of the crane is connected to the hanger 3, the hanger 3 will drive the two transmission plates 44 to rotate around the fixed rod 46, and the two transmission plates 44 will drive the snap plate 41 to slide around the outer wall of the buckle plate 43, so that the two first extrusion plates 42 and the second extrusion plates 45 will approach to squeeze the rope at the output end of the crane, thereby squeezing and fixing the rope at the output end of the crane, and limiting the hook of the crane, thereby preventing the crane from being unhooked during the process of lifting and lowering the steel structure, avoiding the occurrence of safety hazards.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
