[0039] Example 1

[0040] like Figures 1 to 3 As shown, this utility model provides an auxiliary fixing device for a straight ladder, including a connecting frame 100, a fixing member, and a positioning mechanism;

[0041] The connecting frame 100 is sleeved on the outside of the straight ladder 200. The fixing member is detachably provided on the side plate of the connecting frame 100. The connecting frame 100 and the straight ladder 200 are fixed by the fixing member. The positioning mechanism is connected to the connecting frame 100 and is used to fix the positioning mechanism to the abutment of the straight ladder 200.

[0042] In this embodiment, the auxiliary fixing device for the straight ladder includes a connecting frame 100, a fixing member, and a positioning mechanism. The connecting frame 100 is sleeved on the outside of the straight ladder 200. The fixing member is detachably provided on the side plate of the connecting frame 100. The fixing member can fix the connecting frame 100 and the straight ladder 200 to each other. When it is necessary to move the position of the connecting frame 100, it is only necessary to remove the fixing member to move the connecting frame 100. The positioning mechanism is connected to the connecting frame 100. In use, the positioning mechanism is fixed to the abutment of the straight ladder 200 to ensure the stability and reliability of the straight ladder 200, reduce the safety risks when people climb, ensure personnel safety, and improve construction efficiency.

[0043] Preferably, the connecting frame 100 has a structure that is open at the top and bottom and hollow inside, that is, the connecting frame 100 is assembled from four metal side plates and does not have a top plate and a bottom plate, so that it can be fitted onto the outside of the straight ladder 200.

[0044] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the positioning mechanism includes a hook assembly 300 and a clamp assembly 301;

[0045] The hook assembly 300 is provided on the side plates of the connecting frame 100 along its own length direction, and the clamp assembly 301 is provided on the side plate of the connecting frame 100 along its own width direction.

[0046] Both the hook assembly 300 and the clamp assembly 301 are detachably connected to the connecting frame 100. The hook assembly 300 and the clamp assembly 301 are used to fix the straight ladder 200 at the abutment point.

[0047] In this embodiment, hook assemblies 300 are detachably installed on the side plates of the connecting frame 100 along its length, and clamping assemblies 301 are detachably installed on the side plate of the connecting frame 100 along its width. When using the straight ladder 200, if the abutment is a grating plate or a similar structure, the hook assemblies 300 are installed on the side plates of the connecting frame 100 for fixation, eliminating the need for clamping assemblies 301. If the abutment is a cylindrical device or a similar structure, clamping assemblies 301 are installed on the side plates of the connecting frame 100 for fixation, eliminating the need for hook assemblies 300. The hook assemblies 300 and clamping assemblies 301 are fixed independently to suit different usage scenarios without interfering with or affecting their fixing effect, thereby increasing the stability when climbing the straight ladder 200 and reducing construction safety risks.

[0048] Of course, if the application scenario of the straight ladder 200 requires both the hook assembly 300 and the clamp assembly 301, the hook assembly 300 and the clamp assembly 301 can be installed on the side wall of the connecting frame 100, and the abutment point can be fixed simultaneously by the hook assembly 300 and the clamp assembly 301.

[0049] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the hook assembly 300 includes a first connecting plate 302 and a hook 303;

[0050] One end of the hook 303 is connected to the first connecting plate 302, and the first connecting plate 302 is detachably connected to the side plates on both sides of the connecting frame 100 along its own length.

[0051] In this embodiment, preferably, both the hook 303 and the first connecting plate 302 are made of metal. When the hook 303 and the first connecting plate 302 are manufactured independently, the first connecting plate 302 is fixed to the hook 303 by welding. Alternatively, the hook 303 and the first connecting plate 302 can be pre-formed as a single unit. Two sets of the first connecting plate 302 and the hook 303 are provided respectively, and can be detachably installed on the side plates on both sides of the connecting frame 100 along its own length direction. When needed, they can be installed symmetrically for use.

[0052] By installing the first connecting plate 302 and hook 303 on the side plates on both sides of the connecting frame 100 along its own length, when the abutment of the straight ladder 200 is a grid plate or a similar structure, the hook 303 can stabilize the straight ladder 200, thereby reducing the risk of climbing.

[0053] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the side plates of the connecting frame 100 along its length are provided with first screw holes, the first connecting plate 302 is provided with first mounting holes, and the first bolt 304 passes through the first mounting holes and the first screw holes in sequence to fix the first connecting plate 302 and the connecting frame 100.

[0054] In this embodiment, to facilitate the installation and disassembly of the first connecting plate 302, first screw holes are respectively provided on the side plates of the connecting frame 100 along its own length direction. At the same time, a first mounting hole is provided on the first connecting plate 302 at the position corresponding to the first screw hole. The first connecting plate 302 and the connecting frame 100 are fixed by passing the first bolt 304 through the first mounting hole and the first screw hole in sequence. On the side of the side plate facing the straight ladder 200, a first nut that can cooperate with the first bolt 304 is used to limit the position, thereby achieving the effect of fixing the first connecting plate 302 and the connecting frame 100 to each other.

[0055] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the clamp assembly 301 includes a second connecting plate 305 and a clamp 306;

[0056] The clamp 306 is connected to the second connecting plate 305, and the second connecting plate 305 is detachably connected to the side plate of the connecting frame 100 along its own width direction.

[0057] In this embodiment, the second connecting plate 305 can be detachably installed on the side plate of either side of the connecting frame 100 along its width direction. When the clamp 306 is required, the second connecting plate 305 can be installed on the corresponding side plate of the connecting frame 100.

[0058] Preferably, the clamp 306 and the second connecting plate 305 are also made of metal so as to have sufficient strength to stabilize the straight ladder 200.

[0059] By installing a second connecting plate 305 and a clamp 306 on the side plate of either side of the connecting frame 100 along its width direction, the clamp 306 can stabilize the straight ladder 200 when the abutment of the straight ladder 200 is a cylindrical device or a similar structure, thereby reducing the risk of climbing.

[0060] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the side plate of the connecting frame 100 along its width direction has a second screw hole, and the second connecting plate 305 has a second mounting hole. The second bolt 307 passes through the second mounting hole and the second screw hole in sequence to fix the second connecting plate 305 and the connecting frame 100.

[0061] In this embodiment, to facilitate the installation and disassembly of the second connecting plate 305, a second screw hole is provided on either side of the connecting frame 100 along its own frame direction. At the same time, a second mounting hole is provided on the second connecting plate 305 at the position corresponding to the second screw hole. The second connecting plate 305 and the connecting frame 100 are fixed by passing the second bolt 307 through the second mounting hole and the second screw hole in sequence. On the side of the side plate facing the straight ladder 200, a second nut that can cooperate with the second bolt 307 is used to limit the position, thereby achieving the effect of fixing the second connecting plate 305 and the connecting frame 100 to each other.

[0062] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, the clamp 306 includes a first clamp plate 308 and a second clamp plate 309. The first clamp plate 308 is connected to the connecting plate, and the two ends of the first clamp plate 308 are detachably connected to the two ends of the second clamp plate 309.

[0063] In this embodiment, to facilitate the clamping of the clamp 306 onto the cylindrical device, the clamp 306 is configured as two independent clamping plates, namely a first clamping plate 308 and a second clamping plate 309. The two ends of the first clamping plate 308 are detachably connected to the two ends of the second clamping plate 309. That is, threaded holes are correspondingly provided at the connecting sections of the first clamping plate 308 and the second clamping plate 309. The opening and closing of the first clamping plate 308 and the second clamping plate 309 are controlled by using matching bolts and nuts. Simultaneously, to facilitate the fixing of the clamp 306 to the connecting frame 100, the first clamping plate 308 is connected to the connecting plate.

[0064] Of course, when using the first clamp 308 and the second clamp 309 to fix the cylindrical equipment, a rubber gasket is provided between the first clamp 308 and the second clamp 309 and the contact surface of the equipment, so as to prevent the metal clamp 306 from damaging the outer wall of the equipment.

[0065] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, the clamp assembly 301 also includes a connecting rod 310, one end of which is connected to the side of the second connecting plate 305 facing the clamp 306, and the other end of which is connected to the side wall of the first clamp plate 308.

[0066] In this embodiment, in order to further strengthen the connection between the first hoop 308 and the second connecting plate 305, a connecting rod 310 is provided. That is, the two ends of the connecting rod 310 are respectively connected to the side of the second connecting plate 305 facing the clamp 306 and the side wall of the first hoop 308 facing the second connecting plate 305, thereby ensuring the structural strength between the clamp 306 and the second connecting plate 305.

[0067] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the fasteners include a first fastener 400 and a second fastener 401;

[0068] The side plates on both sides of the connecting frame 100 along its own length direction are also provided with first positioning holes. One end of the first fixing member 400 passes through the first positioning hole and abuts against the side wall of the straight ladder 200 to fix the connecting frame 100 and the straight ladder 200.

[0069] The side plate of the connecting frame 100 away from the clamp assembly 301 along its own width direction has a second positioning hole. One end of the second fixing member 401 passes through the second positioning hole and abuts against the ladder beam 201 of the straight ladder 200 to cooperate with the first fixing member 400 to fix the connecting frame 100 and the straight ladder 200.

[0070] In this embodiment, the side plates of the connecting frame 100 along its length are provided with first positioning holes, and the side plate of the connecting frame 100 away from the clamp assembly 301 along its width is provided with second positioning holes. By using the first fixing member 400 to pass through a positioning hole and abut against the side wall of the straight ladder 200, the connecting frame 100 and the straight ladder 200 are initially fixed. Then, one end of the second fixing member 401 passes through the second positioning hole and abuts against the ladder beam 201 of the straight ladder 200, and the relative fixation between the connecting frame 100 and the straight ladder 200 is completed in conjunction with the first fixing member 400.

[0071] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, both the first fixing member 400 and the second fixing member 401 are set screws.

[0072] In this embodiment, the set screw can effectively provide axial clamping force to position the connecting frame 100 and the straight ladder 200 and prevent rotation between them. The set screw is simple and convenient to install and remove, which makes it easy for users to install and remove the connecting frame 100. In order to cooperate with the use of the set screw, both the first positioning hole and the second positioning hole are threaded holes so that the set screw can be threadedly engaged with the threaded hole to provide clamping force.

[0073] Of course, the first fixing member 400 and the second fixing member 401 can also be flat-end fastening screws. The ends of such screws are flat and will not damage the straight ladder 200 when they come into contact with it, and can effectively fix the connecting frame 100 and the straight ladder 200.

[0074] In summary, the specific process of using the auxiliary fixing device for a straight ladder provided in this embodiment is as follows: First, the connecting frame 100 is sleeved on the outside of the straight ladder 200, and the connecting frame 100 is adjusted to be flush with the ladder beam 201 of the straight ladder 200. The first fixing member 400 and the second fixing member 401 provided on the side wall of the connecting frame 100 are screwed in to fix the position of the connecting frame 100. Then, the type of positioning mechanism is selected according to the application scenario. When the abutment of the straight ladder 200 is a grid plate or a similar structure, the hook assembly 30 is used. When the abutment of the straight ladder 200 is a cylindrical device or a similar structure, the clamp assembly 301 is used. After selecting the positioning mechanism, the corresponding clamp 306 or hook 303 is engaged with the abutment to complete the fixation of the straight ladder 200. The whole process is simple to operate, and the contact area between the straight ladder 200 and the operating position is increased as much as possible, thereby increasing the stability of the straight ladder 200 and reducing the safety risks of construction. At the same time, all components are detachable, making disassembly and assembly convenient and preventing damage to the equipment, thus ensuring construction efficiency.

[0075] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
