Description

Technical Field

[0001] The utility model belongs to the technical field of pump pipe equipment, in particular to a reinforcement device for a bent section of a concrete pump pipe. Background Art

[0002] Pump pipe, short for concrete pump pipe, is a new type of construction engineering accessory, available in both truck-mounted and ground-mounted versions. Because pump pipes transport concrete, each bend in the pipe is subject to significant impact force. Therefore, existing equipment incorporates support structures at these bends to improve pumping efficiency and service life. However, existing reinforcements for these bends are fixed and cannot be adjusted to meet actual usage, making them impractical.

[0003] After searching, for example (authorization announcement number CN209469875U), a support device for the bend of a concrete pump pipe is found, which includes a pump pipe support base, a vertical pump pipe fixing member, and a horizontal pump pipe fixing member. A vertical pump pipe fixing member and a horizontal pump pipe fixing member are respectively provided on the top of the pump pipe support base, and the bottom of the horizontal pump pipe fixing member is fixedly connected to the pump pipe support base; the bottom of the vertical pump pipe fixing member is fixedly connected to the pump pipe support base via a support frame, and the pump pipe support base is connected to the ground via high-strength bolts. This device solves the problem that existing equipment cannot provide support and reinforcement for the bend section of the pump pipe when in use. However, because the support structure of this device is fixed, the device cannot be changed according to the actual construction environment and construction requirements, and its applicability is low, which reduces the practicality of the device.

[0030] like Figures 1 to 5 As shown,

[0031] This embodiment includes:

[0032] The bottom of the base plate 1 is provided with a brake caster for easy steering and fixing. Through the setting of the brake caster, the device can be moved and fixed at any time, which is convenient for use. The bottom of the base plate 1 is screwed with a drive motor 12 that provides power.

A connecting rod for mobile support is welded to the bottom of the circular plate 8. The other end of the connecting rod slides with the inner wall of the annular slide 11. The slide 11 is set at the top of the base plate 1. By controlling the rotation of the output shaft of the drive motor 12, the connecting rod welded at the bottom of the circular plate 8 is driven to rotate in the slide 11. The setting of the connecting rod can make the circular plate 8 more stable when rotating, thereby improving the structural stability of the device.

[0033] A fixed block 18 is welded to the top of the circular plate 8, and the top of the fixed block 18 is movably connected to the movable block 7. A slot for facilitating movement is provided at the end of the fixed block 18, an insert block is provided at the bottom of the movable block 7, and a through-type connecting hole is provided on the side wall of the insert block. The side wall of the fixed block 18 is provided with a fastening bolt for facilitating connection, and the fastening bolt passes through the connecting hole to complete the position adjustment of the connection between the insert block and the slot. A movable groove is provided at the connection between the movable block 7 and the fixed block 18, that is, a semicircular movable groove is provided at the connection between the fixed block 18 and the movable block 7, and the connection between the two completes the splicing of the movable groove. The inner wall of the movable groove is connected to a pressing plate 19 for connecting the concrete pump pipe.

Then, according to the actual usage, the movement of the moving part of the linear motor 5 installed inside the fixed frame 6 is controlled to drive the connecting plate 4 to rise and fall inside the fixed frame 6 until the moving part of the linear motor 5 stops running at the appropriate position, and cooperates with the electric push rod inside the connecting plate 4 to drive the arc plate 14 to move, thereby completing the fixation of the pump pipe.

[0039] Then, according to the bending section of the concrete pump pipe, the movable plate 9 is adjusted to move on the slide rail 2, and the movable plate 9 is fixed to the top of the base plate 1 through the set fasteners 15, and the bolts are adjusted to control the relative height of the movable column 17 and the fixed column 16 to complete the adjustment of the support block 10. Finally, the drive motor 12 is controlled to rotate, driving the circular plate 8 connected to its output shaft to rotate under the action of the connecting rod and the slide 11 to complete the position of the fixed block 18 welded on the top of the circular plate 8, and the connection between the bottom plug of the movable block 7 and the slot set in the fixed block 18 is completed through the movable block 7 and the fastening bolts, so that the pressure plate 19 is in contact with the pump pipe to complete the adjustment and fixation.
