Description

Technical Field

[0001] The invention relates to the technical field of civil construction equipment, in particular to a concrete pouring device for steel tube concrete piles. Background Art

[0002] In conventional engineering reverse construction, some of the columns used are often designed as an integral whole with the basement structural columns, and some of the columns are used as permanent structural columns of the basement in the later stage. Such columns used as permanent structural columns are mostly made of cast steel tube concrete. Since they are used as permanent structural columns, the load conditions of the concrete in the upper and lower parts of the columns are usually inconsistent. The strength grade of the concrete in the steel tube column is often higher than that of the concrete in the lower part of the pile hole. Due to the difference in concrete strength grades, it causes certain difficulties in construction, especially when casting steel tube concrete piles, there is a lack of stable casting equipment to realize the continuous construction and use of steel tube concrete piles.

[0003] Publication No. CN111172987A discloses a concrete pouring device for steel tube concrete piles. It facilitates pumping concrete from a mixing tank into a grouting conduit and then into a pile hole to form steel tube concrete piles and concrete columns. The pouring process reduces construction difficulty and provides good stability during concrete pouring. This not only meets the requirements of high-efficiency construction, saves construction costs, reduces project costs, and can effectively perform grouting operations, but is also suitable for continuous construction of steel tube concrete piles. However, this patent still has the following problems in actual use: Although the concrete pouring device for steel tube concrete piles uses a concrete pump to pump the concrete in the mixing tank into the grouting conduit and then into the pile hole to form the steel tube concrete pile, it is not possible to vibrate the concrete when pouring the concrete pile. In the prior art, the concrete is vibrated by a vibrating rod, but it is inconvenient to put the vibrating rod into the steel pipe when vibrating manually. Pulling the vibrating rod back and forth is not only laborious but also easy to cause the vibrating rod to contact the steel pipe wall, thereby affecting the vibration effect. Since the steel pipe has a small diameter, it is not convenient to move the vibrating rod, thereby affecting the uniform vibration of the steel tube concrete pile.

[0004] Therefore, a concrete pouring device for steel tube concrete piles is proposed to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the concrete pouring device for steel tube concrete piles can achieve all-round vibration of the steel tube concrete piles by adjusting the horizontal rotation direction of the spiral vibrating rod, thereby improving the vibration effect; the multi-angle and multi-spacing vibration mode can not only avoid the spiral vibrating rod from contacting the steel tube wall, thereby affecting the vibration effect, but also, with the characteristics of the spiral at the bottom of the spiral vibrating rod, the spiral vibrating rod can be quickly inserted and slowly withdrawn, which can quickly eliminate bubbles in the concrete and improve the concrete pouring effect; the conveying auger is driven to rotate by the conveying motor, and the structural characteristics of the conveying auger are utilized to achieve continuous conveying of concrete raw materials, thereby avoiding interruptions during concrete pouring, thereby avoiding the phenomenon of broken piles. The specific contents are as follows: The camming mechanism is characterized in that the first rotating motor drives the rotating gear to rotate, and the meshing connection between the rotating gear and the rotating gear ring is utilized to make the rotating gear ring drive the adjusting bracket and the spiral vibrating rod to rotate. By adjusting the horizontal rotation direction of the spiral vibrating rod, the all-round vibration of the steel tube concrete pile can be achieved, thereby improving the vibration effect. When the spacing between the spiral vibrating rods needs to be adjusted, the locking pin is driven to move by pushing the sliding ring upward. When the locking pin is separated from the meshing paddle, the rotating bearing is rotated. Under the action of the meshing paddle and the adjusting gear, the adjusting gear drives the adjusting threaded rod to rotate, so that the limiting threaded sleeve drives the vibrating motor, the connecting block and the spiral vibrating rod to move, thereby achieving the adjustment of the spacing between the spiral vibrating rods. The spiral characteristic of the bottom of the spiral vibrating rod can be utilized to quickly insert the spiral vibrating rod into the concrete, thereby facilitating the vibration of the concrete.

When it is necessary to adjust the pouring height and the vibration depth, the first lifting motor is started to drive the meshing gear to rotate. Under the action of the first bevel gear transmission assembly, the four meshing gears can be rotated synchronously. The meshing connection between the meshing gear and the meshing rack is utilized to realize the height adjustment of the pouring pipe. At the same time, the second lifting motor is started to drive the lifting rotating rod and the second bevel gear transmission assembly to rotate, so that the second bevel gear transmission assembly drives the lifting threaded rod to rotate. At the same time, the lifting threaded sleeve drives the first lifting bracket to move up and down, so as to adjust the height of the spiral vibrating rod and perform all-round vibration of concrete. The rotating worm is driven by the second rotating motor to rotate. The meshing connection between the rotating worm and the rotating worm wheel is utilized, so that the rotating worm wheel drives the second locking disk to rotate. At the same time, the limit card is used to drive the locking sliding sleeve and the locking plug to move by utilizing the sliding connection between the limit card and the spiral bracket.

By utilizing the structural characteristics of the mixing auger, the concrete raw materials can be turned up and down. At the same time, the mixing bracket can be used to drive the first cleaning spiral blade and the second cleaning threaded blade to rotate, which can not only clean the inner walls of the mixing box and the discharge hopper, but also stir the concrete raw materials horizontally, thereby achieving uniform mixing of the concrete raw materials and avoiding uneven mixing of the concrete. By starting the second mixing motor to drive the mixing turbine to rotate, the concrete inside the discharge hopper can be stirred to avoid uneven mixing. When the concrete begins to settle, the concrete is pumped into the pouring connecting pipe and the pouring pipe through the pouring pump for concrete pouring. The conveying auger is driven to rotate by the conveying motor. The structural characteristics of the conveying auger can realize continuous conveying of concrete raw materials, avoiding interruption during concrete pouring, which may lead to broken piles. The valve piston is engaged and connected with the mixing box through the elastic force of the valve telescopic rod and the valve spring. When conveying concrete, the end of the conveying pipe is opened to facilitate the conveying of concrete. When the conveying of concrete is stopped, the conveying pipe can be closed to avoid concrete overflow during concrete mixing, which may affect the pouring efficiency of concrete.

By adjusting the horizontal rotation direction of the spiral vibrating rod 118, the omnidirectional vibration of the steel tube concrete pile can be achieved, thereby improving the vibration effect. When it is necessary to adjust the spacing between the spiral vibrating rods 118, the locking pin 111 is driven to move by pushing the sliding ring 109 upward. When the locking pin 111 is separated from the meshing paddle 106, the rotating bearing 105 is rotated, and the meshing paddle 106 is used to engage the adjusting gear. Under the action of the meshing connection of 114, the adjusting gear 114 drives the adjusting threaded rod 113 to rotate, and the limiting threaded sleeve 115 drives the vibrating motor 116, the connecting block 117 and the spiral vibrating rod 118 to move, thereby realizing the adjustment of the spacing between the spiral vibrating rods 118. The spiral characteristics of the bottom of the spiral vibrating rod 118 can be utilized to quickly insert the spiral vibrating rod 118 into the concrete, which is convenient for vibrating the concrete. Through the multi-angle and multi-spacing vibration method, not only can the spiral vibrating rod 118 be prevented from contacting the steel pipe wall, thereby affecting the vibration effect, but also the bubbles in the concrete can be quickly eliminated, thereby improving the concrete pouring effect.

[0026] Finally, when it is necessary to adjust the height of the pouring and the depth of the vibration, the first lifting motor 122 is started to drive the meshing gear 121 to rotate. Under the action of the first bevel gear transmission assembly 123, the four meshing gears 121 can be rotated synchronously. By utilizing the characteristics of the meshing connection between the meshing gear 121 and the meshing rack 120, the height adjustment of the pouring pipe 119 can be achieved. At the same time, the second lifting motor 137 is started to drive the lifting rotation rod 138 and the second bevel gear transmission assembly 139 to rotate, so that the second bevel gear transmission assembly 139 drives the lifting threaded rod 140 to rotate, and at the same time the lifting threaded sleeve 141 drives the first lifting bracket 101 The lifting and lowering movement makes it easy to adjust the height of the spiral vibrating rod 118 and perform all-round vibration of the concrete. The second rotating motor 127 drives the rotating worm 128 to rotate. The rotating worm 128 and the rotating worm wheel 129 are engaged with each other, so that the rotating worm wheel 129 drives the second locking disk 130 to rotate. At the same time, the limit card 133 is slidably connected with the spiral bracket 125, so that the limit card 133 drives the locking sliding sleeve 132 and the locking plug block 134 to move. The locking plug block 134 is engaged with the meshing rack 120, so that the pouring pipe 119 can be fixed and the pouring stability of the pouring pipe 119 can be improved.
