Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, the rapid towing device for foam hook tubes on a ladder truck includes a mounting plate 101 installed on the ladder truck. The mounting plate 101 is connected to a clamping frame 102 via a suspension structure. The clamping frame 102 is provided with a bearing block 103 for supporting the force-bearing column 105 on the foam hook tube 104. The clamping frame 102 is also provided with a self-clamping structure.

[0024] In this embodiment, the suspension structure connects the clamping frame 102 to the mounting plate 101. When the foam hook tube 104 is hung on the clamping frame 102, the suspension structure drives the self-clamping structure to fix the foam hook tube 104 on the clamping frame 102, which facilitates the placement of the foam hook tube 104 by the ladder truck. After placement, the mounting plate 101 is lowered, and the clamping frame 102 automatically disengages from the foam hook tube 104 to complete the placement of the foam hook tube 104. This method is highly safe and labor-saving and convenient to use.

[0025] In one embodiment, such as Figures 1-2As shown, the suspension structure includes a first fixed seat 201 connected to a mounting plate 101. A first rotating shaft 202 is rotatably connected through the first fixed seat 201. Two parallel first connecting plates 203 are symmetrically connected to the first rotating shaft 202. A second rotating shaft 205 is rotatably connected through one end of the first connecting plate 203 away from the first rotating shaft 202. The second rotating shaft 205 is slidably mounted on a clamping frame 102. A quick-release assembly is provided between the second rotating shaft 205 and the clamping frame 102. A second fixed seat 301 is provided on the mounting plate 101. A third rotating shaft 302 is rotatably connected through the second fixed seat 301. Two parallel second connecting plates 303 are symmetrically connected to the third rotating shaft 302. A fourth rotating shaft 304 is slidably connected through one end of the second connecting plate 303 away from the third rotating shaft 302. The fourth rotating shaft 304 is rotatably mounted through the clamping frame 101. 2. A reset assembly is provided between the clamping frame 102 and the mounting plate 101. The reset assembly includes a first connecting post 401 and a second connecting post 402. The first connecting post 401 is rotatably connected to the clamping frame 102, and the second connecting post 402 is rotatably connected to the second connecting plate 303. A reset spring 403 is connected between the first connecting post 401 and the second connecting post 402. A limiting module is provided on the second fixed base 301. The limiting module includes an L-shaped pin 404 that slides through the second fixed base 301. A third Y-shaped locking pin 405 passes through the L-shaped pin 404. The L-shaped pin 404 contacts the second connecting post 402. In the initial state, the reset spring 403 pulls the first connecting post 401 and the second connecting post 402 to bring them closer to each other. The second connecting plate 303 rotates upward to press the L-shaped pin 404, thus fixing the position of the clamping frame 102.

[0026] In one embodiment, such as Figures 1-3 As shown, a stop block 311 is provided at one end of the fourth rotating shaft 304, and a second Y-shaped pin 312 is provided through the other end of the fourth rotating shaft 304. The quick-release assembly includes a first bushing 204 connected to the clamping frame 102. The first bushing 204 is sleeved on the outside of the second rotating shaft 205. A first Y-shaped locking pin 206 is provided through the first bushing 204 and passes through the second rotating shaft 205. In order to facilitate lubrication and maintenance of the rotating parts, the fourth rotating shaft 304 can be pulled out by pulling out the second Y-shaped pin 312, and the second rotating shaft 205 can be pulled out by pulling out the first Y-shaped locking pin 206, thereby temporarily removing the clamping frame 102 from the mounting plate 101 for easy maintenance.

[0027] In one embodiment, such as Figures 1-3As shown, the self-clamping structure includes a second bushing 305 slidably sleeved on the fourth rotating shaft 304. A first gear 306 is coaxially connected to the outer side of the second bushing 305. A second gear 307 is rotatably connected to the clamping frame 102, and the second gear 307 meshes with the first gear 306. A fifth rotating shaft 308 is rotatably connected through the clamping frame 102. A third gear 309 is coaxially connected to the fifth rotating shaft 308, and the third gear 309 meshes with the second gear 307. A clamping block 310 is connected to the fifth rotating shaft 308 to clamp the force-bearing column 105 on the foam hook tube 104. The support block 103 placed on the clamping frame 102 moves downward under the gravity of the foam hook tube 104. The second connecting plate 303 and the fourth rotating shaft 304 do not rotate, but the fourth rotating shaft 304 rotates relative to the clamping frame 102. That is, the second bushing 305 and the first gear 306 rotate relative to the clamping frame 102. The first gear 306 drives the third gear 309 to rotate through the second gear 307. The third gear 309 drives the pressing block 310 to rotate through the fifth rotating shaft 308, pressing down the force column 105 and achieving stable clamping.

[0028] In one embodiment, such as Figure 2 As shown, the clamping block 310 has anti-slip teeth on the side near the bearing block 103 to improve the clamping firmness of the clamping block 310 on the force-bearing column 105.

[0029] In one embodiment, such as Figure 1 As shown, a support wheel 406 is rotatably connected to the side of the clamping frame 102 away from the mounting plate 101. When the foam hook tube 104 contacts the clamping frame 102, it first contacts the support wheel 406, which reduces the friction that may be generated between the foam hook tube 104 and the clamping frame 102, reduces the interference of the friction between the foam hook tube 104 and the clamping frame 102 on the clamping stability, and improves the stability of the clamping frame 102 in clamping the foam hook tube 104.

[0030] The above embodiments disclose a foam hook tube quick-towing device for a ladder truck. In the initial state, the return spring 403 pulls the first connecting column 401 and the second connecting column 402 closer together. The second connecting plate 303 rotates upward to press the L-shaped pin 404, fixing the position of the clamping frame 102. The force-bearing column 105 on the foam hook tube 104 is placed on the bearing block 103 on the clamping frame 102. Under the action of the gravity of the foam hook tube 104, the clamping frame 102 moves downward. The second connecting plate 303 and the fourth rotating shaft 304 do not rotate. The fourth rotating shaft 304 rotates relative to the clamping frame 102. Rotation occurs when the second bushing 305, together with the first gear 306, rotates relative to the clamping frame 102. The first gear 306 drives the third gear 309 to rotate via the second gear 307. The third gear 309 drives the clamping block 310 to rotate via the fifth rotating shaft 308, pressing down on the force-bearing column 105 to achieve stable clamping. After the foam hook tube 104 is installed in place, the mounting plate 101 is moved downward. Under the action of the return spring 403, the suspension structure is reset, releasing the clamping block 310 from the force-bearing column 105, thereby achieving the separation of the foam hook tube 104 from the clamping frame 102, making it convenient and safe to use.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
