Description

Technical Field

[0001] This utility model relates to the field of crane lifting equipment technology, and in particular to a crane lifting equipment with a self-locking component. Background Technology

[0002] Crane spreaders are key components used for lifting and moving heavy objects. Their design and selection directly affect the safety and efficiency of operations. Depending on different application scenarios and needs, crane spreaders can be divided into various types, each with its specific functions and applicable scope.

[0003] The existing announcement number CN212403163U, entitled "A Crane Lifting Tool," includes a mounting hole, a connecting ring, and a nut. A mounting base is provided at one end of the mounting hole, and a connecting hole is connected to one side of the mounting base. An iron chain is connected to one side of the connecting hole, and a fixing ring is fixedly connected to one side of the iron chain. A support rod is provided on one side of the fixing ring, and a spring is fixedly installed at one end of the support rod. A retractable rod is connected to one side of the spring, and a groove is fixedly installed on one side of the retractable rod. A fixing rod is provided on one side of the groove, and a lifting plate is fixedly installed on one side of the connecting ring. A telescopic rod is fixedly connected inside the lifting plate, and a telescopic rod is fixedly connected inside the telescopic rod. This crane lifting tool allows the iron chain to be replaced according to the size of the object by setting bolts on the iron chain. The fixing ring on the iron chain prevents the iron chain from tangling during up-and-down movement. A connecting rod and a connecting block are provided inside the lifting plate to adjust the length of the lifting plate.

[0004] However, the aforementioned crane lifting device uses a manually adjustable retractable rod to control the distance between the two lifting plates to meet the needs of cargo lifting. The crane lifting device does not have a self-locking component during lifting, and manual adjustment is required, which increases the lifting steps and reduces the ease of lifting. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a crane lifting device with a self-locking component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a crane lifting device with a self-locking component, comprising a lifting device body and a lifting component. The lifting device body includes a lifting frame and a locking component. The lifting frame is a vertically arranged U-shaped structure, and a bracket is horizontally fixed at the bottom of the vertical end face of the lifting frame. Locking components are provided on both sides of the horizontal end face of the lifting frame, and a lifting slide frame is vertically fixed in the middle of the horizontal end face of the lifting frame. The lifting component includes a lifting plate, which is vertically slidably inserted into the lifting slide frame. A lifting hole for a hook is horizontally opened through the top surface of the lifting plate. The locking component includes a guide frame and a compression clamping frame. The guide frame is horizontally slidably assembled on the horizontal end face of the lifting frame, and a compression clamping frame is vertically fixed on the bottom surface of the guide frame. A lifting bar is hinged to the top surface of the guide frame, and the other end of the lifting bar is hinged to the lifting plate.

[0007] As a preferred embodiment, a hole seat is vertically fixed on the top surface of the guide frame, and the hole seat is hinged to one end of the lifting strip.

[0008] As a preferred embodiment, a perforated block is vertically fixed on the outer wall of the lifting plate, and the perforated block is hinged to the other end of the lifting strip.

[0009] As a preferred option, a sliding block is fixed to the bottom of the lifting plate, and the sliding block is vertically slidably assembled in the lifting frame.

[0010] As a preferred option, triangular hole brackets are horizontally provided on both symmetrical vertical end faces of the lifting plate, and the triangular hole brackets are fixed to the outer wall of the lifting plate.

[0011] As a preferred embodiment, vertical rods are fixed on both sides of the horizontal end face of the hanging frame, and the vertical rods are slidably inserted into the triangular hole frame.

[0012] As a preferred embodiment, both ends of the lifting strip are fixed with rotating frames, and the rotating frames are rotatably connected to the hole seat and the hole block, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the object to be lifted is placed on the bracket below the lifting frame of the lifting device body, and then the lifting hole and hook at the top of the lifting plate are installed. During lifting, the lifting bar slides vertically in the lifting slide frame on the top surface of the lifting frame, and the sliding lifting plate moves vertically in the lifting slide frame. The hinge pulls the lifting bar to slide laterally on the horizontal plane of the lifting frame, and pulls the guide frame to slide laterally on the horizontal plane of the lifting frame, which drives the squeezing clamp frame to squeeze and hold the two sides of the object to be lifted, thereby lifting, locking and holding the object to be lifted, and ensuring the stability during lifting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, a crane lifting device with a self-locking component includes a lifting device body 1 and a lifting component 2. The lifting device body 1 includes a lifting frame 11 and a locking component 13. The lifting frame 11 is a vertically arranged U-shaped structure, and a bracket 12 is horizontally fixed to the bottom of the vertical end face of the lifting frame 11. Locking components 13 are provided on both sides of the horizontal end face of the lifting frame 11, and a lifting slide frame 14 is vertically fixed to the middle of the horizontal end face of the lifting frame 11. The lifting component 2 includes a lifting plate 21, which is vertically slidably inserted into the lifting slide frame 14. A lifting hole 23 for a hook is horizontally opened through the top surface of the lifting plate 21. The locking component 13 includes a guide frame 131 and a compression clamping frame 132. The guide frame 131 is horizontally slidably assembled on the horizontal end face of the lifting frame 11, and the compression clamping frame 132 is vertically fixed to the bottom surface of the guide frame 131. A lifting bar 25 is hinged to the top surface of the guide frame 131, and the other end of the lifting bar 25 is hinged to the lifting plate 21. A slide block 22 is fixed to the bottom end of the lifting plate 21, and the slide block 22 is vertically slidably assembled in the lifting slide frame 14. In use, the object to be lifted is placed on the bracket 12 below the lifting frame 11 of the lifting device body 1, and then the lifting hole 23 at the top of the lifting plate 21 is hoisted with the hook. During hoisting, the lifting bar 25 slides vertically in the lifting slide frame 14 on the top surface of the lifting frame 11, and the sliding lifting plate 21 moves vertically in the lifting slide frame 14. The hinge pulls the lifting bar 25 to slide laterally on the horizontal plane of the lifting frame 11, and pulls the guide frame 131 to slide laterally on the horizontal plane of the lifting frame 11, which drives the squeezing clamp frame 132 to squeeze and clamp the two sides of the object to be lifted, thereby locking and clamping the object to be lifted, ensuring the stability during hoisting.

[0027] In one embodiment, such as Figure 4 and Figure 5 As shown, a hole seat 133 is vertically fixed on the top surface of the guide frame 131, and the hole seat 133 is hinged to one end of the lifting strip 25. A hole block 26 is vertically fixed on the outer wall of the lifting plate 21, and the hole block 26 is hinged to the other end of the lifting strip 25. A rotating frame 251 is fixed at both ends of the lifting strip 25, and the rotating frame 251 is rotatably connected to the hole seat 133 and the hole block 26 respectively. During hoisting, the lifting strip 25 slides vertically in the lifting slide frame 14 on the top surface of the lifting frame 11, and the sliding lifting plate 21 moves vertically in the lifting slide frame 14. The hinged pull causes the rotating frames at both ends of the lifting strip 25 to rotate on the hole seat 133 and the hole block 26 respectively, and pulls the horizontal plane of the lifting frame 11 to slide and clamp the hoisted object.

[0028] In one embodiment, such as Figure 4 and Figure 5As shown, triangular hole frames 24 are horizontally provided on both sides of the symmetrical vertical end face of the lifting plate 21, and the triangular hole frames 24 are fixed on the outer wall of the lifting plate 21. Vertical rods 15 are vertically fixed on both sides of the horizontal end face of the lifting frame 11, and the vertical rods 15 are slidably inserted into the triangular hole frames 24. In order to ensure the vertical sliding displacement distance of the lifting plate 21 during use, the lifting plate 21 slides vertically on the vertical rods 15, which vertically drives the lifting plate 21 to slide vertically on the vertical rods 15.

[0029] In this embodiment, the object to be lifted is placed on the bracket 12 below the lifting frame 11 of the lifting device body 1. Then, the lifting hole 23 at the top of the lifting plate 21 is connected to the hook for lifting. During lifting, the lifting bar 25 slides vertically in the lifting slide frame 14 on the top surface of the lifting frame 11. The sliding lifting plate 21 moves vertically in the lifting slide frame 14. The hinge pulls the lifting bar 25 to slide laterally on the horizontal plane of the lifting frame 11, and pulls the guide frame 131 to slide laterally on the horizontal plane of the lifting frame 11, which drives the squeezing clamp frame 132 to squeeze and clamp the two sides of the object to be lifted.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
