Detailed Embodiments

[0016] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings in the specification and specific embodiments.

[0017] Referring to Figure 1As shown in the figure, an embodiment of the present application discloses a portable support device, which includes: a main body 1 and a threaded rod 11. The threaded rod 11 is arranged in the main body 1 through threaded connection; a sleeve 2, which is rotatably installed with the threaded rod 11; a mounting plate 21, which is arranged on the sleeve 2 and is detachably connected to a mobile climbing ladder; a first spherical block 31, which is fixedly arranged on the main body 1; a base 4; a spherical cavity, which is arranged on the base 4, and the first spherical block 31 is installed in the spherical cavity. The outer wall surface of the first spherical block 31 is in sliding contact with the inner wall surface of the spherical cavity; a cover plate 41, which is used to cover the spherical cavity.

[0018] During specific use, install this support device on the mobile climbing ladder, and the sleeve 2 is fixedly connected to the mobile climbing ladder; by a staff member turning the threaded rod 11, the threaded rod 11 can be driven to rotate around its own central axis. The rotation of the threaded rod 11 can push the main body 1 towards the ground along the axial direction, make the base 4 contact the ground, and lift the entire mobile climbing ladder a certain height off the ground.

[0019] In the present utility model, by arranging the first spherical block 31 on the main body 1, the base 4 and the main body 1 are connected through the first spherical block 31. The base 4 can rotate in multiple directions around the first spherical block 31, so as to adapt to ground with different inclinations, and can effectively increase the contact area between the support device and the ground, achieving the purpose of stably supporting the mobile climbing ladder.

[0020] Furthermore, the device further includes: a bearing 51, which is used to connect the sleeve 2 and the threaded rod 11; specifically, the outer ring of the bearing 51 and the sleeve 2 are installed through interference fit, and the inner ring of the bearing 51 and the threaded rod 11 are installed through interference fit.

[0021] The device further includes a through groove 52, which is opened on the main body 1 along the axial direction of the threaded rod 11; a through hole 53, which is opened on the sleeve 2 and is below the threaded rod 11; a bolt assembly, which can pass through the through hole 53 and the through groove 52 and is used to support the threaded rod 11.

[0022] It can be understood that the bolt assembly at least includes a screw rod and a nut. The screw rod passes through the through hole 53 and the through groove 52 and supports the threaded rod 11, preventing the thread between the threaded rod 11 and the main body 1 from failing due to the large weight when a staff member works on the mobile climbing ladder, and further ensuring the safety of the staff member.

[0023] It can be understood that on both sides of the sleeve 2, the axial movement of the screw rod along the through hole 53 is restricted by nuts respectively.

[0024] Specifically, two mounting plates 21 are arranged on the sleeve 2. Pass the mobile climbing ladder through the mounting plates 21 and lock it with a bolt assembly; it can be flexibly disassembled and assembled on the mobile climbing ladder, facilitating the replacement and maintenance of the support device.

[0025] Referring to Figure 2 as shown, the device further includes: a mounting plate 65, disposed on the main body 1 and parallel to the base 4; a plurality of mounting holes, arranged in a circumferential array on the mounting plate 65 with the main body 1 as the center; a plug pin 61, slidably disposed in the mounting hole; a second spherical block 32, disposed at one end of the plug pin 61 for contacting the base 4; a spring 62, disposed between the second spherical block 32 and the mounting plate 65 for providing a movement tendency for the second spherical block 32 to approach the base 4.

[0026] In this embodiment, by providing a plurality of plug pins 61 and springs 62, when the base 4 is not in contact with the ground, the spring 62 can support the base 4 to be in a horizontal state; after the base 4 contacts the ground and tilts, the base 4 can squeeze the spring 62 to push the plug pin 61 to slide in the mounting hole and adjust according to the actual angle of the ground.

[0027] By providing the second spherical block 32, disposed at one end of the plug pin 61 for contacting the base 4, it can effectively reduce the contact area between the plug pin 61 and the base 4, reduce friction, and reduce wear.

[0028] Further, the device further includes: a first limiting plate 63 and a second limiting plate 64, both disposed on the plug pin 61; wherein, the first limiting plate 63 is between the spring 62 and the second spherical block 32, and the second limiting plate 64 is on the side of the mounting plate 65 away from the second spherical block 32.

[0029] Further, the device further includes: a turntable 71 and a handle 72, the turntable 71 is disposed at one end of the threaded rod 11, and the handle 72 is disposed on the turntable 71 parallel to the threaded rod 11; the staff can drive the threaded rod 11 to rotate by holding the handle 72 to rotate the turntable 71 to complete the support operation; of course, along the radial direction of the turntable 71, the handle 72 and the threaded rod 11 are installed at a certain distance from each other to increase the force arm.
