Description

Technical Field

[0001] The utility model relates to the technical field of concrete pumps, in particular to a concrete pump with supporting feet. Background Art

[0002] A concrete pump is a machine that uses pressure to continuously transport concrete along a pipeline.

[0003] Most of the existing concrete pump support leg installation methods are vertical. The concrete pump is supported by a jack manually, and then the height of the support legs is adjusted to make the concrete pump suspended in the air. Another method is to use a hydraulic telescopic rod to adjust the height to achieve the stability of the concrete pump. However, after the hydraulic telescopic rod is extended and retracted, the height from the ground is limited. When passing through uneven roads, the hydraulic telescopic rod may be damaged by collision, thereby affecting the use effect of the concrete pump. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art in that the concrete hydraulic contraction height is fixed and the hydraulic contraction rod is protected, and proposes a concrete pump with supporting feet.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A concrete pump with a support leg comprises a concrete pump body and a mounting plate for mounting the concrete pump body, a plurality of first fixing blocks and a plurality of second fixing blocks provided with waist holes being fixedly connected on both sides of the mounting plate, two adjacent first fixing blocks being rotatably connected to each other via a rotating shaft, the other ends of the two support rods being commonly fixedly connected to a connecting block, the bottom end of the connecting block being fixedly connected to a support plate, one side of the second fixing block being rotatably connected to an electric hydraulic rod, one end of the electric hydraulic rod being rotatably connected to a rotating block, and the other end of the rotating block being rotatably connected to the connecting block.

[0007] Furthermore, one end of the concrete pump body is fixedly connected to a material storage trough.

[0008] Furthermore, a feed port is provided on the top of the storage tank.

[0009] Furthermore, a discharge port is provided on one side of the storage trough.

[0010] Furthermore, rollers are rotatably connected to both sides of the mounting plate.

[0011] Furthermore, one end of the outer wall of the electric hydraulic rod is fixedly connected to a bellows, and the other end of the bellows is fixedly connected to the rotating block.

[0012] Furthermore, a control panel is provided on one side of the concrete pump body.

[0013] The beneficial effects of the utility model are:

[0014] 1. By arranging the electric hydraulic rods on both sides of the mounting plate, the height of the electric hydraulic rods from the ground can be raised, thereby avoiding collision between the electric hydraulic rods and the ground and improving the use effect of the concrete pump.

[0015] 2. By driving the rotating block to move under the tension of the electric hydraulic rod, the support rod is rotated downward, so that the support plate contacts the ground. The electric hydraulic rod continues to stretch so that the support rod continues to rotate downward, thereby lifting the mounting plate and the concrete pump body upward, thereby adjusting the height of the concrete pump body.

[0016] 3. The electric hydraulic rod is protected by a corrugated cover to prevent concrete from falling on the telescopic rod of the electric hydraulic rod, so as not to affect the telescopic operation of the electric hydraulic rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4A concrete pump with a support leg includes a concrete pump body 2 and a mounting plate 1 for mounting the concrete pump body 2. A plurality of first fixing blocks 6 and a plurality of second fixing blocks 601 are welded on both sides of the mounting plate 1. A waist hole is provided between the first fixing block 6 and the plurality of second fixing blocks 601. Two adjacent first fixing blocks 6 are rotatably connected to each other by a rotating shaft. The support rods 11 can move within a small range on the first fixing block 6. The other ends of the two support rods 11 are welded together with a connecting block 10. The bottom end of the connecting block 10 is fixed with a support plate 12 by bolts.

[0024] One side of the second fixed block 601 is rotatably connected to the mounting end of the electric hydraulic rod 7 through a pin shaft. The mounting end of the electric hydraulic rod 7 can move within a small range on the second fixed block 601. One end of the electric hydraulic rod 7 is rotatably connected to the rotating block 9 through a joint bearing. The other end of the rotating block 9 is rotatably connected to the connecting block 10 through a pin shaft. There is a suitable rotation gap between the rotating block 9 and the connecting block 10 to avoid stroke problems. Under the tension of the electric hydraulic rod 7, the rotating block 9 is driven to move, thereby causing the support rod 11 to rotate downward, thereby causing the support plate 12 to contact the ground, increasing friction, and making parking more stable.

[0025] When stowed, the electric hydraulic rod 7 contracts, the rotating block 9 moves upward, and the support plate 12 is out of contact with the ground, allowing the device to move; it should be noted that the waist holes on the first fixed block 6 and the plurality of second fixed blocks 601 and the rotation gap between the rotating block 9 and the connecting block 10 can cooperate with the rotating block 9 to rotate in an arc trajectory, avoiding stroke problems, so that the support plate 12 can rotate freely in a space at a certain height above the ground;

[0026] One end of the concrete pump body 2 is fixed with a storage trough 3 by bolts. The top of the storage trough 3 is provided with a feed port 4, and one side of the storage trough 3 is provided with a discharge port 13. The material is put into the storage trough 3 from the feed port 4 and then discharged from the discharge port 13. Rollers 5 are rotatably connected to both sides of the mounting plate 1 to facilitate the movement of the concrete pump body 2. A bellows 8 is fixed to one end of the outer wall of the electric hydraulic rod 7 by bolts, and the other end of the bellows 8 is fixedly connected to the rotating block 9. The electric hydraulic rod 7 is protected by the bellows 8 to prevent concrete from falling on the telescopic rod of the electric hydraulic rod 7, so as not to affect the extension and retraction of the electric hydraulic rod 7. A control panel 14 is provided on one side of the concrete pump body 2.

[0027] The working principle of this embodiment is as follows: when in use, the rotating block 9 is driven to move under the tension of the electric hydraulic rod 7, so that the support rod 11 is rotated downward, and the support plate 12 is in contact with the ground. The electric hydraulic rod 7 continues to stretch so that the support rod 11 continues to rotate downward, so that the mounting plate 1 and the concrete pump body 2 are lifted upward, thereby adjusting the height of the concrete pump body 2. When not in use, the rotating block 9 is retracted under the drive of the contraction of the electric hydraulic rod 7, so that the support rod 11 is rotated upward, thereby retracting the support plate 12.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
