DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] See also Figure 1 to Figure 2 , which is a schematic diagram of a hydraulic conveyor that can be fixed on the ground provided by the utility model. The hydraulic conveyor that can be fixed on the ground includes a base 10 and a bracket 20 connected to the upper end of the base 10; a brake assembly 30 arranged at the bottom of the base 10, and a supporting assembly arranged between the base 10 and the bracket 20. It can be imagined that the hydraulic conveyor that can be fixed on the ground also includes other functional components and specific structures, such as electrical connection components, mounting structures, etc., which are all technologies well known to those skilled in the art, so they are not described one by one here.

[0023] The base 10 is a central block structure. Four chair legs 11 extending radially outward and distributed in a circumferential manner are arranged on the circumferential outer wall of the base 10. The chair legs 11 are evenly stressed. In this embodiment, it is an integrated structure with high structural strength. A universal roller 12 is connected to the bottom of the end of each chair leg 11 away from the base 10. The universal roller 12 contacts the bottom surface to achieve the transfer of the conveyor. At the same time, the height of the base 10 is set by the universal roller 12, so that the overall center of gravity of the conveyor is close to the lower end. In addition, a roller brake is movably arranged on the universal roller 12. The roller brake is rotated or slid to abut against the outer wall of the universal roller 12 to achieve the braking of the universal roller 12. The universal roller 12 and the roller brake are both existing technologies in the field, so they will not be described here.

[0024] Specifically, the brake assembly 30 includes a brake cylinder 31 disposed at the bottom of the base 10, a drivable push rod 32 is disposed at the bottom of the brake cylinder 31, and a chassis 33 is rotatably connected to one end of the push rod 32 away from the brake cylinder 31. The brake cylinder 31 controls the extension and retraction of the push rod 32 of the brake cylinder 31 through an external switch, and drives the chassis 33 to rise and fall at the lower end of the base 10. When the conveyor needs to be fixed in position, when the chassis 33 is driven by the brake cylinder 31 to descend and contact the ground, the chassis 33 fits the ground and is not easy to tip over, while increasing the contact area between the bottom of the conveyor and the ground, thereby increasing the retention stability of the conveyor.

[0025] A spherical embedding groove 34 is provided at the bottom of the chassis 33. In this embodiment, the spherical embedding groove 34 is a hemispherical structure embedding structure. One end of the push rod 32 passes through the chassis 33 and is connected to a spherical portion 35 correspondingly embedded in the spherical embedding groove 34. The spherical portion 35 is an independent structure with an internal thread provided therethrough. One end of the push rod 32 is threadedly connected to the spherical portion 35. Under this structural design, the chassis 33 and the push rod 32 can be movably rotated. When the bottom surface of the fixed position is slightly tilted, the chassis 33 contacts the ground in advance, and the spherical portion 35 is in a fixed state in actual use. The chassis 33 can still adaptively and stably fit the bottom surface by relying on its own mobility to ensure the retention stability of the conveyor.

[0026] An outer wall of the push rod 32 is provided with an angle limiting step 36 located at the upper end of the chassis 33. An end of the angle limiting step 36 close to the spherical portion 35 is provided with an angle slope 37. The angle limiting step 36 limits the chassis 33 from moving upward under force. At the same time, the angle slope 37 is used to limit the upper limit of the rotation angle of the chassis 33 to prevent the chassis 33 from detaching or rotating too much.

[0027] An annular cushion 38 is provided on the circumferential outer wall of the chassis 33 and the cross section of the annular cushion 38 is U-shaped. The annular cushion 38 can increase the fit of the chassis 33 and also act as a buffer when the base 10 moves, thereby avoiding safety issues such as pinching of hands.

[0028] The outer diameter of the chassis 33 is greater than the outer diameter of the base 10 , which increases the area of ​​the base 10 and tends to move the overall center of gravity downward.

[0029] The bottom of the chair leg 11 is provided with a height limiting step 13 that can be connected to the upper end of the chassis 33. The chair leg 11 is tilted and has an angle with the base 10. A clearance gap 39 is provided between the base 10 and the chassis 33. Under normal conditions, the chassis 33 abuts against the lower end of the height limiting step 13, which increases the stability of the structure of the chassis 33 when it is not in operation and avoids collision and other problems. The clearance gap 39 between the base 10 and the chassis 33 further avoids the large-area adhesion between the base 10 and the chassis 33, which may cause safety problems such as pinching the hands after the base 10 rises.

[0030] The upper end of the base 10 is provided with a hydraulic pusher 40 connected to the bracket 20. The hydraulic pusher 40 controls the lifting and lowering of the bracket 20 and can maintain pressure to play a supporting role. In this embodiment, the upper end of the bracket 20 is provided with a concave clamping groove 21, which is used to support the load so that the load is more stably held on the bracket 20. The load can be transferred by a single or multiple hydraulic conveyors.

[0031] The outer wall of the hydraulic pusher 40 is provided with a gripping handle 41 , which provides a gripping point on the outer wall of the hydraulic pusher 40 to avoid directly gripping the rod structure of the hydraulic pusher 40 to generate safety risks.

[0032] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
