Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, and in particular to a load-bearing beam structure with climbing claws. Background Technology

[0002] As a core piece of equipment for the vertical transportation of materials and personnel in high-rise building construction, the installation efficiency of traction construction hoists directly affects project progress and construction costs. The load-bearing beam is the core structural component supporting the traction machine, counterweight, and cage; its fixing must ensure structural strength and stability. Common fixing methods include: pre-embedded steel plate welding, direct embedding in concrete beams, high-strength bolt anchoring, and bolt-welded combination of steel structure shafts.

[0003] Load-bearing beams are mostly installed at the top of the shaft (reaching heights of over 100 meters), requiring workers to operate in confined spaces, posing risks of falls and being struck by falling objects. Furthermore, traditional scaffolding is costly to erect, necessitating the use of mobile lifting platforms or suspended safety baskets. Additionally, heavy load-bearing beams (each weighing 2-5 tons) require tower cranes or truck cranes for hoisting, but the narrow space at the top of the shaft and the frequent conflicts between hoisting paths and building structures necessitate the use of hoisting tools, which carries significant safety risks. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a load-bearing beam structure with climbing claws, which can be used in conjunction with an automatically lifting climbing frame. The climbing claws enable switching between support and movement on the shaft wall, reducing installation difficulty.

[0005] Therefore, the technical solution of this utility model is: a load-bearing beam structure with climbing claws, including a load-bearing beam body, with climbing claws rotatably installed at both ends of the load-bearing beam body; the climbing claws are provided with a first working end and a second working end, the first working end is placed inside the load-bearing beam body, and a counterweight is installed on the first working end; the second working end extends out of the load-bearing beam and inserts into a hole in the shaft wall; when the load-bearing beam moves upward, the climbing claws rotate downward until the second working end leaves the hole.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the second working end of the climbing claw is in contact with the bottom surface of the hole, and the load-bearing beam body is in a supported state; when the climbing claw moves upward, the second working end abuts against the top surface of the hole, the second working end deflects downward to disengage from the hole, and the load-bearing beam body is in a moving state.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the counterweight block drives the bottom edge of the climbing claw to fit against the bottom surface of the load-bearing beam body, and the climbing claw is horizontal and extends out to the second working end.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the climbing claw has a triangular structure, with the apex rotatably mounted on the end of the load-bearing beam body via a cylindrical pin, and the two bottom corners being the first working end and the second working end, respectively.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the end of the load-bearing beam body is provided with multiple pin holes, and the climbing claw is rotatably installed in any pin hole through a cylindrical pin.

[0010] This utility model is used in conjunction with a climbing frame with an automatic lifting function. The climbing frame climbs within the shaft based on the climbing formwork principle. The load-bearing beam is mounted on the climbing frame and is moved upward by the climbing frame. Before construction, multiple holes are evenly opened on the shaft wall to facilitate the sequential insertion of the climbing claws at both ends of the load-bearing beam into the holes during the climbing process, thereby achieving a supported and fixed state. After the load-bearing beam moves to the target height, it can be directly fixed using the climbing claws, which is simple and convenient.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The flip-up climbing claw enables the switching between the supporting and moving states of the load-bearing beam. When the climbing claw is not under force, the presence of the counterweight keeps it horizontal, and the second working end of the climbing claw extends into the hole in the shaft wall to achieve the supporting function. When the load-bearing beam moves upward, the second working end of the climbing claw is pressed down by the hole in the shaft wall, while the first working end and the counterweight tilt upward synchronously, and the second working end leaves the hole, achieving the moving function of the load-bearing beam. When the climbing claw moves to the next hole, it resets under the action of the counterweight, causing the second working end to re-insert into the hole in the shaft wall. This alternating process allows the load-bearing beam to automatically rise under the drive of the climbing frame, improving the installation efficiency of the construction hoist.

[0020] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and 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, and 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. They should not be construed as limiting the specific protection scope of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0022] See the attached drawings. The load-bearing beam structure with climbing claws described in this embodiment includes a load-bearing beam body 1, with climbing claws 2 rotatably mounted at both ends of the load-bearing beam body 1; the ends of the load-bearing beam body 1 are provided with multiple pin holes 11, and the climbing claws 2 are rotatably mounted in any of the pin holes 11 through cylindrical pins 3. By selecting different pin holes 11, the length of the climbing claws 2 can be adjusted, which can be used in wells with dimensional deviations.

[0023] The climbing claw 2 has a triangular structure, with its apex rotatably mounted on the end of the load-bearing beam body 1 via a cylindrical pin 3. The two base corners are the first working end 21 and the second working end 22, respectively. The first working end 21 is located inside the load-bearing beam body 1, and a counterweight 23 is mounted on it. The counterweight 23 drives the bottom edge of the climbing claw 2 to fit against the bottom surface of the load-bearing beam body 1, thereby limiting the rotation angle of the climbing claw. The climbing claw 2 is horizontal and extends beyond the second working end 22 to increase the contact area for force application.

[0024] The second working end 22 can be inserted into the hole 41 in the shaft wall 4; the bottom surface of the hole 41 in the shaft wall 4 is a horizontal plane, and the top surface of the hole is an inclined surface 42; the second working end 22 of the climbing claw 2 is in contact with the bottom surface of the hole 41, and the load-bearing beam body 1 is in a supported state; when the load-bearing beam body 1 moves upward, the climbing claw 2 rotates downward due to the pressure of the shaft wall as it moves upward away from the hole, so that the second working end 22 abuts against the inclined surface 42 of the hole, and the second working end 22 deflects downward until it moves away from the hole 41, so that the load-bearing beam body 1 can move upward. When it moves to the next hole position, the pressure of the shaft wall on the second working end disappears, and it resets under the action of the counterweight of the first working end, and is re-inserted into the next hole.

[0025] This embodiment is used in conjunction with a climbing frame 5 that has an automatic jacking function. The climbing frame 5 climbs within the shaft based on the climbing formwork principle. Specifically, the climbing frame 5 is equipped with a hydraulic jacking component 6. Several pre-embedded climbing cones 71 and guide shoes 72 are provided within the shaft. Climbing guide rails 8 are hung on the guide shoes, and evenly distributed step plates are provided on the climbing guide rails 8. The hydraulic jacking component 6 includes a hydraulic cylinder 61 and reversing boxes 62 installed at both ends of the hydraulic cylinder 61. A pawl 63 is rotatably installed inside the reversing box 62. A reversing plate fixedly connected to the pawl 63 is provided on the outside of the reversing box 62, and a return spring 64 is provided on the reversing plate. The hydraulic cylinder 61 drives the two reversing boxes 62 to move upward alternately. The pawls 63 in the two reversing boxes 62 alternately pass over the step plates and, under the action of the return spring, abut against the upper surface of the step plates, thereby realizing the automatic jacking function.

[0026] The load-bearing beam body 1 is mounted on the climbing frame 5 and is moved upward by the climbing frame 5. Before construction, multiple holes 41 are evenly opened on the shaft wall 4 so that the climbing claws 2 at both ends of the load-bearing beam body 1 can be inserted into the holes 41 in sequence during the climbing process to achieve a support and fixation state. After the load-bearing beam body 1 moves to the target height, it can be directly fixed by using the climbing claws 2, which is simple and convenient.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
