Description

Technical Field

[0001] The utility model belongs to the technical field of climbing frames, in particular to a bottom closing device of a climbing frame. Background Art

[0002] Climbing frames, also known as lifting frames, can be divided into several main categories according to their power sources, including hydraulic, electric, and manual types. They are mainly used in high-rise shear wall buildings. They can climb up or down along the building and are not restricted by the height of the building, which greatly saves manpower and materials.

[0003] Climbing frames generally use protective flaps to fill and seal the gap between the climbing frame and the building to prevent people and objects from falling. Since the protective flap needs to be removed or folded up during the climbing process of the climbing frame, if the protective flap is removed, the protective flap needs to be fixed in place in the climbing frame to facilitate the next installation. Therefore, the existing technology often adopts a folding method, such as connecting the protective flap to the fixed pedal through a hinge; and the hinge connection position is set at the upper part of the protective flap and the fixed pedal, so that the protective flap can be folded around the hinge to the top of the fixed pedal for storage. However, when an object falls on the flap, the impact force on the flap causes the flap to tend to fold down to the bottom of the fixed pedal. Therefore, the force will act on the hinge, causing the hinge to loosen or damage. The protective flap is only connected to the fixed pedal through a hinge, so there is a risk of the protective flap falling. Utility Model Content

[0004] In view of this, the purpose of the present invention is to overcome the deficiencies in the prior art and provide a bottom closure device for a climbing frame. The present application provides the following technical solutions:

[0005] It includes a fixed pedal and a flap. The bottom of the flap close to the fixed pedal is hinged to the fixed pedal through a hinge. The flap can be folded toward the bottom of the fixed pedal. The top of the flap close to the fixed pedal is spliced ​​and locked with the fixed pedal through a locking structure.

[0006] The flap includes a panel, a baffle is provided at the bottom of one end of the panel close to the fixed pedal, a folding edge is provided at the bottom of the baffle, one end of the hinge is connected to the folding edge, and the other end is connected to the fixed pedal.

[0007] A rib is also provided at the bottom of the panel, and one end of the rib is connected to the baffle to form a stable structure.

[0008] The locking structure includes a protrusion provided on the flap and a groove provided on the fixed pedal. The protrusion fits in with the groove and their positions correspond. The protrusion can be spliced ​​with the groove.

[0009] Through holes are provided on the protrusion and in the groove. When the protrusion is assembled with the groove, fixing bolts are passed through the through holes to fix the protrusion.

[0010] A latch is sleeved on the protrusion, a limiting protrusion is provided at the bottom of the latch, a locking hole is provided in the groove, and the limiting protrusion can pass through the locking hole and then be engaged with the locking hole.

[0011] The locking structure includes a buckle and a hook respectively provided on the fixed pedal and the flap, and the buckle can be engaged with the hook to fix the fixed pedal and the flap.

[0012] A hydraulic telescopic rod is provided below the fixed pedal, and one end of the hydraulic telescopic rod is hinged to the flap.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] The hinge between the flap and the fixed pedal is set at the bottom, and the top is connected with a special locking structure. After the connection of the locking structure is cancelled, the flap can be folded toward the bottom of the fixed pedal for storage. When the flap is subjected to force, most of the force acts on the locking structure. The hinge is subjected to little force and is not easily damaged. The top is connected by a locking structure. The locking structure is specifically used for detachable connection between the flap and the fixed pedal. It does not need to serve as not only a connecting part but also a rotating axis like the hinge in the prior art. Therefore, more designs can be adopted, and it can be set to a structure with higher connection strength. Moreover, the flap is folded downward relative to the fixed pedal. Even if an accident occurs, the locking structure is disconnected under force, and the flap will also fold toward the bottom of the fixed pedal to unload the force, and the flap will not fall and cause secondary injury.

[0015] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0025] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0026] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0027] Please refer to Figure 1-6As shown, a climbing frame bottom closing device provided by the utility model includes a fixed pedal 1 and a flap 2. The bottom of the flap 2 close to the fixed pedal 1 is hinged to the fixed pedal 1 through a hinge 4. The flap 2 can be folded toward the bottom of the fixed pedal 1. The top of the flap 2 close to the fixed pedal 1 is spliced ​​and locked with the fixed pedal 1 through a locking structure 3.

[0028] Among them, in addition to the solutions described in the following embodiments, the locking structure 3 has many optional designs, whose main function is to connect and fix the flap 2 to the fixed pedal 1, and the connection can be canceled and disconnected; therefore, any connection structure that can play this role in the prior art may be used as the locking structure 3 in this solution. Of course, when actually used, it should comply with construction specifications and the connection strength should meet the standards.

[0029] The flap 2 includes a panel 21 , a baffle 22 is provided at the bottom of one end of the panel 21 close to the fixed pedal 1 , a folded edge 23 is provided at the bottom of the baffle 22 , one end of the hinge 4 is connected to the folded edge 23 , and the other end is connected to the fixed pedal 1 .

[0030] A rib 24 is further provided at the bottom of the panel 21 , and one end of the rib 24 is connected to the baffle 22 to form a stable structure.

[0031] In an optional solution, the locking structure 3 includes a protrusion 31 provided on the flap 2 and a groove 32 provided on the fixed pedal 1 . The protrusion 31 and the groove 32 fit together and have corresponding positions. The protrusion 31 can be assembled with the groove 32 .

[0032] Through holes are provided on the protrusion 31 and in the groove 32 . When the protrusion 31 and the groove 32 are assembled, fixing bolts 33 are passed through the through holes to fix them.

[0033] During specific implementation, the protrusion 31 is assembled into the groove 32 and then fixed by the fixing bolt 33. When the climbing frame goes up and the flap 2 needs to be folded up, the fixing bolt 33 is unscrewed to fold the flap 2 around the hinge 4 to the bottom of the fixed pedal 1, and the protrusion 31 and the groove 32 are no longer assembled.

[0034] Alternatively, a latch 34 is sleeved on the protrusion 31, a limiting protrusion 341 is provided at the bottom of the protrusion 34, a locking hole 35 is provided in the groove 32, and the limiting protrusion 341 can pass through the locking hole 35 and engage with the locking hole 35, such as Figure 5 shown.

[0035] The locking pin 34 is rotated so that the wider portion of the limiting protrusion 341 is engaged with the narrower portion of the locking hole 35. At this time, the upper portion of the locking pin 34 limits the protrusion 31, and the limiting protrusion 341 limits the bottom of the groove 32, so that the protrusion 31 and the groove 32 are spliced ​​and fixed. When the climbing frame goes up and the flap 2 needs to be folded, the locking pin 34 is rotated so that the limiting protrusion 341 corresponds to the wider portion and the narrower portion of the locking hole 35. The limit can be cancelled, and the protrusion 31 and the groove 32 can move relative to each other, so that the flap 2 can be folded around the hinge 4 to the bottom of the fixed pedal 1.

[0036] like Figure 6 As shown, in another optional solution, the locking structure 3 includes a buckle and a hook respectively arranged on the fixed pedal 1 and the flap 2, and the buckle can be engaged with the hook to fix the fixed pedal 1 and the flap 2; wherein the buckle is preferably a safety buckle, which will not be opened at will during use.

[0037] Furthermore, in order to reduce the amount of operation for construction workers, a hydraulic telescopic rod 5 is provided under the fixed pedal 1. One end of the hydraulic telescopic rod 5 is hinged to the flap 2, and the other end is hinged to the climbing frame. The hydraulic telescopic rod 5 automatically extends and retracts to push the flap 2 to rotate around the hinge 4, thereby realizing automatic expansion and contraction. At the same time, since the hydraulic telescopic rod 5 is provided, it can be used as a support member, so a locking structure 3 may not be provided between the flap 2 and the fixed pedal 1; it is worth noting that there is a design in the prior art that sets a hydraulic telescopic rod 5 to drive the flap 2 to fold, but since the flap 2 is folded toward the top of the fixed pedal 1, the hydraulic telescopic rod 5 must be provided above the fixed pedal 1, which will affect the construction workers. In this solution, the flap 2 is folded toward the bottom of the fixed pedal 1, so the hydraulic telescopic rod 5 is provided below the fixed pedal 1, which will not cause any impact when the construction workers are constructing on the fixed pedal 1.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
