Description

Technical Field

[0001] The invention relates to the technical field of lifting and hoisting equipment, and in particular to an independent hook and a hooking method. Background Art

[0002] During the construction process, it is often necessary to transport some objects by hanging. There are two main existing ways to hook objects. The first method is to make the hook part protrude / recessed, and to hook through the tenon / groove. The tenon needs to be inserted into one side of the object or the groove needs to wrap one side of the object, and then the object can be hooked along the hooking channel. However, when the bottom of the object is completely touched and the hooking surface is flat and smooth, the object cannot be hooked. The second method is that the end face of the hook forms a certain angle / opening (generally an acute angle or a right angle) to hook through the angle, but when there is not enough space at the outer end of the object or there is no groove of sufficient depth on the outer wall, the object cannot be hooked. It can be seen that the above two hooks are not suitable for narrow and long spaces.

[0003] In summary, developing an independent hook that can quickly and stably hook objects of various shapes in a narrow and long space is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] The purpose of the present invention is to provide an independent hook and a hooking method, which solves the technical problem that when the existing hook is used, both the object and the hooking environment must meet specific conditions, resulting in a small scope of application.

The support rod includes a plurality of connecting rods hinged to each other. The connecting rods are all hinged to the end surface of the adjacent connecting rods facing away from the first elastic member. The support rod can only bend toward the side close to the first elastic member.

[0012] Preferably, two ends of the first elastic member are rotatably connected to the fixed arm and the telescopic rod respectively.

[0013] Preferably, a handle is sleeved on one end of the fixed arm away from the first carrying plate, and the end of the handle is wrapped with a pipe sleeve.

[0014] Preferably, a pressure sensor is provided on one side of the first supporting plate close to the first elastic member. When the object is fully pushed onto the first supporting plate, the object abuts against the pressure sensor, and the pressure sensor prompts the operator to complete the hooking through a warning light.

[0015] Accordingly, the present application also provides a hooking method applicable to the above-mentioned independent hook, comprising:

[0016] Control the telescopic component to swing to the side away from the fixed arm, so that the first carrying plate is separated from the second carrying plate, and control the first carrying plate and the second carrying plate to extend into the narrow space, so that the ends of the first carrying plate and the second carrying plate abut against the side wall of the object;

[0017] The handle is swung toward the side close to the telescopic component, so that the second carrying plate slides along the side wall of the object to the bottom of the object, and the first elastic member pulls the telescopic rod, so that part of the object slides onto the second carrying plate;

[0018] The handle is dragged laterally toward the side close to the fixed arm, so that the first carrying plate moves toward the bottom of the object, and the second elastic member applies an upward elastic force to the second carrying plate, so that the second carrying plate lifts the object and moves the object onto the first carrying plate;

The ends of the first carrier plate and the second carrier plate are in contact with the side wall of the object, and the fixed arm is tilted toward the side close to the telescopic component, and the second carrier plate is slid to the bottom of the object along the side wall of the object. At this time, the fixed arm is dragged toward the side close to the original position of the fixed arm to move the end of the first carrier plate to the bottom of the object. Since the second carrier plate is supported between the bottom surface of the narrow space and the bottom of the object, this swing causes the telescopic component to stretch, and the rebound tendency of the telescopic component causes the second carrier plate to apply an oblique upward thrust to the object. At the same time, the first elastic member pulls the fixed arm and the telescopic component, and the second carrier plate pushes the object against the first carrier plate, fixes the object to the independent hook, and can perform hooking operations in a narrow space.

[0030] 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.

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Please refer to the instruction manual Figure 1The present application provides an independent hook, which includes a fixed arm 1 and a telescopic component. The end of the telescopic component is hinged on the side wall of the fixed arm 1, and the rotation axis of the telescopic component is perpendicular to the fixed arm 1, that is, the end of the telescopic component can swing to the side close to the end of the fixed arm 1. A first elastic member 6 is connected between the fixed arm 1 and the telescopic component. The first elastic member 6 enables the fixed arm 1 and the telescopic component to move toward each other. A second bearing plate 5 and a first bearing plate 2 are respectively provided at the end on the same side of the telescopic component and the fixed arm 1, and the first bearing plate 2 and the second bearing plate 5 extend in opposite directions. Under the action of the first elastic member 6, the first bearing plate 2 and the second bearing plate 5 can clamp an object disposed therebetween. When the independent hook of the present application is used to hook an object in a narrow space, the fixed arm 1 and the telescopic component are rotated to the side away from each other. It should be noted that the lengths of the first bearing plate 2 and the second bearing plate 5 are adjustable. The first bearing plate 2 and the second bearing plate 5 are extended into the narrow space so as to abut against the side wall of the object and clamp the object under the action of the first elastic member 6. The fixed arm 1 is swung toward the side close to the telescopic component, and the telescopic component moves accordingly. The connection between the telescopic component and the fixed arm 1 is offset toward the side close to the narrow space, so that the second carrier plate 5 moves in the narrow space toward the side close to the bottom of the object until the end of the second carrier plate 5 contacts the bottom surface of the object. The end of the second carrier plate 5 is inserted between the bottom surface of the object and the bottom surface of the narrow space under the pull of the first elastic member 6. Then, the fixed arm 1 is swung to the original position, so that the first carrier plate 2 also moves toward the side close to the bottom surface of the object, so that the end of the first carrier plate 2 corresponds to the bottom surface of the object. Since the second carrier plate 5 is fixed between the object and the narrow space The telescopic component is stretched during the swinging process of the fixed arm 1, and the restoring elastic force generated by the telescopic component is applied to the bottom surface of the object through the second supporting plate 5, lifting the object upward. In addition, the two ends of the first elastic member 6 pull the fixed arm 1 and the telescopic component, and the first supporting plate 2 and the second supporting plate 5 move toward each other. The second supporting plate 5 pushes the object to the upper end surface of the first supporting plate 2. Subsequently, the fixed arm 1 is swung again toward the end close to the telescopic component, so that both sides of the object are located on the first supporting plate 2 and the second supporting plate 5. Finally, the fixed arm 1 is restored to its original position, completing the fixation of the object and the independent hook, which is convenient for subsequent hooking operations.

[0033] Preferably, the first elastic member 6 is rotatably connected to the fixed arm 1 and the telescopic rod 4 through a hinge pin. During the swinging of the fixed arm 1 and the telescopic rod 4, the first elastic member 6 can swing accordingly to prevent the first elastic member 6 from bending during the stretching process, changing the force direction of the fixed arm 1 and the telescopic rod 4, and affecting the hooking effect of the independent hook.

[0034] Preferably, the telescopic component includes a swing rod 3 and a telescopic rod 4, the swing rod 3 is connected to the fixed arm 1 through a swing shaft, a sliding cavity 31 is provided at the end of the swing rod 3 away from the swing shaft, the sliding cavity 31 extends along the axis of the swing rod 3 to the side close to the swing shaft, and the telescopic rod 4 is slidably arranged inside the sliding cavity 31. It should be noted that the inner cavity diameter of the sliding cavity 31 is larger than the port diameter of the sliding cavity 31, and a baffle 41 is provided at the end of the telescopic rod 4 close to the swing shaft. The cross section of the baffle 41 is the same as the cross section of the sliding cavity 31, and the diameter of the baffle 41 is larger than the port diameter of the sliding cavity 31 and It is slightly smaller than the inner cavity diameter of the sliding cavity 31, that is, the baffle 41 cannot be moved out of the sliding cavity 31, preventing the telescopic rod 4 from separating from the swing rod 3. In addition, a second elastic member 7 is provided between the baffle 41 and the port of the sliding cavity 31. The diameter of the second elastic member 7 is larger than the port diameter of the sliding cavity 31. The two ends of the second elastic member 7 are respectively abutted against the side wall of the baffle 41 and the port of the sliding cavity 31. When the telescopic rod 4 extends out of the sliding cavity 31, it drives the baffle 41 to compress the second elastic member 7. The reaction force of the second elastic member 7 causes the telescopic rod 4 to pull the second supporting plate 5, and the second supporting plate 5 can lift the object.

[0035] It should be noted that the first carrier plate 2 is vertically arranged with the fixed arm 1, and the angle between the second carrier plate 5 and the telescopic rod 4 is an acute angle. When no object is clamped between the first carrier plate 2 and the second carrier plate 5, the first carrier plate 2 is in contact with the ground, and the ends of the first carrier plate 2 and the second carrier plate 5 are butted. At this time, the first carrier plate 2 and the second carrier plate 5 are parallel and coplanar. Preferably, grooves 9 are provided on the end faces of the first carrier plate 2 and the second carrier plate 5 close to the swing axis. The grooves 9 of the first carrier plate 2 and the second carrier plate 5 have the same size. When the independent hook does not clamp an object, the ends of each groove 9 are aligned. A accommodating cavity is formed, and a support rod 8 is provided on one side end face of the first supporting plate 2 where a groove 9 is provided. The support rod 8 is hinged to the fixed arm 1, and the support rod 8 extends into the accommodating cavity. The size of the support rod 8 matches the accommodating cavity, that is, the two ends of the support rod 8 respectively abut against the side walls opposite to the groove 9 of the first supporting plate 2 and the second supporting plate 5, thereby determining the positional relationship between the first supporting plate 2 and the second supporting plate 5, and preventing the first elastic member 6 from excessively pulling the fixed arm 1 and the telescopic rod 4, so that the first supporting plate 2 and the second supporting plate 5 are staggered and stacked, affecting the normal use of the independent hook.

[0036] Preferably, the support rod 8 is composed of several hinged connecting rods. In one embodiment of the present application, the support rod 8 is composed of two hinged connecting rods, wherein the connecting rod close to the fixed arm 1 is recorded as the first connecting rod, and the connecting rod away from the fixed arm 1 is recorded as the second connecting rod. The first connecting rod is hinged to the fixed arm 1, and the size of the second connecting rod is slightly smaller than the size of the first connecting rod. A hinge groove is provided on the end face of the first connecting rod on the side away from the first elastic member 6, and the hinge groove is located at the end of the first connecting rod away from the fixed arm 1, and the end of the second connecting rod is arranged in the hinge groove, so that the second connecting rod can only swing to the side facing the end of the hinge groove, that is, the second connecting rod can only swing downward relative to the first connecting rod. When the first supporting plate 2 and the second supporting plate 5 clamp objects, the support rod 8 is placed on the top of the object. When the object is pushed onto the first supporting plate 2, the support rod 8 is bent to prevent the support rod 8 and the first supporting plate 2 from squeezing the object and hindering the object from extending into the first supporting plate 2.

[0037] An inclined surface 11 is provided on the opposite ends of the first supporting plate 2 and the second supporting plate 5. The inclined surface 11 is used to guide the objects to move to the end surfaces of the first supporting plate 2 and the second supporting plate 5. Preferably, the inclined surface 11 is inclined to the side away from the first elastic member 6, and the ends of the first supporting plate 2 and the second supporting plate 5 have sharp plug-in portions to facilitate each inclined surface 11 to extend into the bottom of the object.

[0038] A pressure sensor (not shown in the figure) is provided on the end face of the first supporting plate 2 close to the first elastic member 6. The pressure sensor is provided on the side of the first supporting plate 2 close to the fixed arm 1. When the object is fully set on the first supporting plate 2, it abuts against the pressure sensor. The pressure sensor informs the operator through a warning light that the hooking of the object is completed. In addition, a handle 10 is provided on the end of the fixed arm 1 away from the first supporting plate 2. The end of the handle 10 is wrapped with a tube sleeve to facilitate the operator to hold the fixed arm 1.

[0039] Accordingly, the present invention also provides a hooking method, which is applicable to the above-mentioned independent hook. Figure 2 To Attachment Figure 6, swing the telescopic component to the side away from the fixed arm 1, so that there is a sufficient distance between the ends of the first supporting plate 2 and the second supporting plate 5 to accommodate the object, and respectively abut the ends of the first supporting plate 2 and the second supporting plate 5 on the two side walls of the object, and operate the handle 10 to swing it to the side close to the telescopic component. At this time, the baffle 41 of the telescopic rod 4 is located at the bottom of the sliding cavity 31, and the telescopic component cannot be compressed. The fixed arm 1 pushes the telescopic component to move the side wall of the second supporting plate 5 that is attached to the object to the side close to the bottom of the object, and the plug-in portion at the end of the second supporting plate 5 extends between the bottom surface of the object and the bottom surface of the narrow space. At this time, the position of the second supporting plate 5 is locked. Then, the handle 10 is swung toward the side close to the fixed arm 1, so that the end of the first supporting plate 2 is attached to the side wall of the object and slides to the bottom of the object. Since the second supporting plate 5 is locked, that is, the telescopic rod 4 is locked in position, when the handle 10 is swung toward the side close to the fixed arm 1, the fixed arm 1 drives the swing rod 3 to move together, the baffle 41 is locked in position, and the port of the sliding cavity 31 moves toward the side close to the fixed arm 1. The second elastic member 7 located between the baffle 41 and the port of the sliding cavity 31 is compressed. When the first supporting plate 2 reaches the bottom of the object, the second elastic member 7 applies a thrust to the object through the telescopic rod 4 and the second supporting plate 5. The thrust direction is along the extending direction of the telescopic component. The thrust pushes the object through the inclined surface 11 of the first supporting plate 2. Under the guidance of the first carrier plate 2, the object slides to the top surface of the first carrier plate 2 and slides toward the side close to the fixed arm 1. Similarly, the handle 10 swings toward the side close to the telescopic component again, and the second carrier plate 5 lifts the object through the elastic force of the second elastic member 7, so that the object is simultaneously carried on the end surfaces of the first carrier plate 2 and the second carrier plate 5. In addition, the first elastic member 6 pulls the fixed arm 1 and the telescopic rod 4 on both sides, and the second carrier plate 5 continues to push the object. When the object is stably set on the first carrier plate 2, the object abuts the pressure sensor, and the pressure sensor prompts the operator to complete the fixation of the object and the independent hook through the warning light. Finally, the fixed arm 1 is restored to the vertical state through the handle 10, and subsequent hooking work can be carried out.

[0040] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0041] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
