Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The application provides a climbing frame, wherein the climbing frame 10 comprises a plurality of climbing frame joints, at least one of the climbing frame joints is a falling prevention joint 11, a hook 111 is fixedly arranged on the falling prevention joint 11, and an opening of the hook 111 faces downwards to hook a hook hanging piece below the hook 111.
When the climbing frame 10 is dropped due to an unstable connection, the anti-drop joint 11 can be engaged with a hook member on a mounting base to which the climbing frame is connected to provide a safe connection for standby, preventing the climbing frame 10 from further dropping.
Wherein, the opening of the hook 111 faces downwards, when the climbing frame falls, the hook can be jointed with the hook hanging piece below, thereby establishing a new mechanical connection between the climbing frame 10 and the mounting base 20, preventing the climbing frame 10 from continuously falling, and improving the operation safety.
Preferably, as shown in fig. 1, the hook 111 is disposed toward the inside of the climbing frame 10, so as to fully utilize the existing arrangement of the climbing frame 10 and the mounting seat 20, and avoid occupying additional space.
A hook 111 can be provided at a suitable location on the fall arrest joint 11, for example, the fall arrest joint 11 includes a connection lug 112, and the hook 111 can be provided at the connection lug 112. To simplify the structure and facilitate the manufacturing, a hook portion may be formed on a side portion of the engaging lug plate 112 to form the hook 111.
According to another aspect of the present application, there is provided a jacking device, wherein the jacking device 200 comprises a main body 210 and a plurality of mounting seats 20 circumferentially arranged at the bottom of the main body, at least one of the mounting seats 20 is a falling-prevention mounting seat 21, the jacking device 200 comprises a hook 22 corresponding to the falling-prevention mounting seat 21, the falling-prevention mounting seat 21 is provided with a sliding hole 211, the hook 22 can slide along the sliding hole 211, and the hook 22 is arranged to be able to be kept on a vertical moving path of a corresponding climbing frame joint of a climbing frame 10 in a natural state.
When the climbing frame 10 is installed, the climbing frame 10 moves vertically upwards relative to the installation seat 20, and since the hook 22 is naturally kept on the vertical moving path of the climbing frame joint, the climbing frame joint pushes the hook 22 to move along the sliding hole 211 (as shown by a in fig. 3) in the process of moving upwards to allow the hook 22 to be opened (as shown by b in fig. 3), so that the climbing frame 10 continues to move upwards to a proper position and then completes installation, and the hook 22 returns to the natural state to be positioned below the climbing frame joint (as shown by c in fig. 3) after being opened. When the climbing frame 10 is dropped, the corresponding portion of the climbing frame joint (e.g., the hook 111) will move downward toward the hook member 22 and eventually engage the hook member 22, thereby establishing a new mechanical connection between the climbing frame 10 and the mount 20, preventing the climbing frame 10 from continuing to drop.
Wherein the hooking member 22 can be maintained in a natural state (i.e. without external force) in a suitable manner on the vertical movement path of the climbing frame joint. For example, the hook member 22 may be spring biased to lie in the vertical path of travel of the climbing frame joint. For simplicity of design, the sliding hole 211 is a straight hole inclined downward in a direction toward the outside of the climbing frame 10. Therefore, the corresponding part (such as the hook 111) of the climbing frame joint can push away the hook 22 only by overcoming the gravity of the hook 22, and the hook 22 slides to the lowest point (i.e. natural state) along the sliding hole 211 under the action of self-weight after passing through the hook 111.
In the present application, the hooking member 22 may be in various suitable forms as long as it is easy to be hooked by the hooking hook 111. Specifically, the hooking member 22 may be a pin.
The sliding hole 211 can be arranged according to the specific structure of the anti-falling mounting seat 21. In the embodiment shown in fig. 6 to 8, the fall preventing mounting seat 21 includes a pair of mounting lugs 212, the sliding holes 211 are provided on the mounting lugs 212, the hook member 22 is disposed through the sliding holes 211 on the pair of mounting lugs 212, and the sliding holes 211 are provided on the mounting lugs 212. In order to mount the climbing frame 10 after the climbing frame 10 is moved to the proper position, the mounting ear plate 212 is provided with a mounting hole 213 for mounting the anti-falling joint 11, and the mounting hole 213 is located outside the sliding hole 211, that is, the mounting hole 213 is located closer to the outside of the climbing frame 10 with the climbing frame 10 as a reference. Correspondingly, the climbing frame 10 is also provided with a mounting hole 113 corresponding to the mounting hole 213, and the hook 111 is located inside the mounting hole 113.
Wherein the mounting hole 213 may be located above the sliding hole 211, i.e. the mounting hole 213 is located above the highest position of the hook member 22, so that upon a fall of the climbing frame 10 a backup connection is established by the hook member 22 after a short fall, so as to perceptively indicate to the operator on the climbing frame 10 that the fall has occurred.
In addition, as shown in fig. 6, it is preferable that the mounting ear plate 212 is provided with a prompting hole 214, the hook member 22 is configured to be able to be drawn out from the sliding hole 211 and inserted into the prompting hole 214, and the prompting hole 214 is configured to enable the hook member 22 to be kept on a vertical moving path of the climbing frame joint when being inserted. Specifically, the hooking member 22 is disposed in the sliding aperture 211 during installation of the climbing frame 10 to provide a backup connection for the climbing frame 10. When the climbing frame 10 is detached, the hook member 22 can be drawn out and inserted into the prompting hole 214, so that when the climbing frame 10 is installed again, an operator is reminded to draw out the hook member 22 from the prompting hole 214 and insert the hook member into the sliding hole 211 to prevent the climbing frame 10 from dropping. Specifically, if the hook member 22 is still inserted into the prompting hole 214 when the climbing frame 10 is installed, the hook member 22 will obstruct the movement of the climbing frame joint when the climbing frame 10 moves upwards, thereby prompting the operator that the hook member 22 has not been inserted into the sliding hole 211 and the continued installation has a safety risk.
In the case where the hook member 22 is inserted into the sliding hole 211, the hook member 22 may be prevented from being separated from the sliding hole 211 by stopping from both ends of the hook member 22 by a detachable auxiliary member (for example, both ends of the hook member 22 are provided with threads and a nut is used as an auxiliary member). When the hook member 22 needs to be pulled out, the nut is firstly detached.
In order to enable the hook member 22 to be positioned on the vertical moving path of the climbing frame joint when being inserted into the prompting hole 214, the prompting hole 214 is arranged above or below the sliding hole 211, for example, the prompting hole 214 can be positioned right above or right below the lower middle position of the sliding hole 211.
Wherein, the jacking body 210 may be a transition section or an upper support according to the type of the tower crane, and fig. 4 and 9 show embodiments in which the jacking device includes the transition section and the upper support, respectively. Specifically, for a flat-head tower crane, the climbing frame 10 is installed on a transition section, the jacking main body 210 is the transition section, and as shown in fig. 4, the installation seat 20 is arranged on the transition section; for a hammer tower crane, the climbing frame 10 is mounted on a lower support, the jacking body 210 is the lower support, and as shown in fig. 9, the mounting seat 20 is arranged on the lower support.
According to another aspect of the application, a mounting structure of a climbing frame is provided, wherein the mounting structure comprises the climbing frame 10 of the application and a jacking device of the application, the mounting seat 20 comprises a falling prevention mounting seat 21 corresponding to the falling prevention joint 11 and a hook piece 22, the falling prevention mounting seat 21 is provided with a sliding hole 211, and the hook piece 22 can slide along the sliding hole 211 and is arranged to be capable of being kept on a vertical moving path of the hook 111 in a natural state.
Thus, when the climbing frame 10 is installed, the climbing frame 10 moves vertically upward relative to the mounting seat 20, and since the hook 22 is naturally kept on the vertical moving path of the hook 111, the hook 111 of the anti-falling joint 11 pushes the hook 22 to move along the sliding hole 211 (as shown by a in fig. 3) during the upward movement to allow the hook 22 to let open (as shown by b in fig. 3), so that the anti-falling joint 11 continues to move upward to the position and then the installation is completed, and the hook 22 returns to the natural state to be positioned below the hook 111 (as shown by c in fig. 3) after letting through the anti-falling joint 11. When the climbing frame 10 is dropped, the hook 111 will move downward toward the hook member 22 and eventually engage the hook member 22, thereby establishing a new mechanical connection between the climbing frame 10 and the mount 20, preventing the climbing frame 10 from continuing to drop.
In addition, as shown in fig. 6 to 8, the mounting base 20 may include a bottom plate 215, a cover plate 216, a vertical plate 217 and a cover plate 218, wherein the mounting ear plate 212 is fixed (e.g., welded) to the lower side of the bottom plate 215 perpendicular to the bottom plate 215, the cover plate 216 and the vertical plate 217 are respectively fixed to the upper side of the bottom plate 215, and the cover plate 216 may be fixed to extend to the transition section or the main body portion of the upper support.
