Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal construction, in particular to a municipal cast-in-place pile construction device. Background Art
[0002] A cast-in-place pile is a pile made by first drilling a hole in the ground and then pouring concrete or reinforced concrete into the hole. It has the advantages of no vibration, no soil squeezing and little noise during construction. Therefore, cast-in-place piles are suitable for use in areas with densely populated urban buildings. After the drilling is completed, the inner wall needs to be protected.
[0003] Bentonite has great adhesion when mixed with water, and it is cheap, so it is widely used in the architectural coating industry. The montmorillonite in bentonite can cross-link with the organic matter in the coating to form a three-dimensional network structure, which increases the consistency of the coating and improves its suspension and anti-settling properties. Therefore, it can be used as an inorganic thickener and suspension anti-settling agent; because bentonite has good adhesion and hiding power, it can replace part of the film-forming material in the preparation of the coating as an auxiliary binder; once the bentonite-organic complex is generated, it becomes a hydrophobic substance after dehydration, so it can improve the water resistance and washability of the coating, and at the same time improve the brushability and leveling properties. The application of bentonite in architectural coatings has achieved good results in reducing costs and improving performance, and has improved economic benefits.
[0004] However, during the production of bentonite, the viscosity of the bentonite itself makes the mixing efficiency of the traditional stirring device insufficient, which in turn affects the effect of the finished product. Therefore, there are certain limitations.
[0005] For this reason, we urgently need to provide a kind of municipal cast-in-place pile construction device. Utility Model Content
[0006] The utility model aims to provide a municipal bored pile construction device to solve the problem in the above background technology that during production, the viscosity of bentonite itself makes the mixing efficiency of the traditional stirring device insufficient, thus affecting the effect of the finished product.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal bored pile construction device, comprising a mixing tank and support columns, wherein four support columns are respectively fixedly connected to the four corners of the lower surface of the mixing tank, and a mixing device is arranged inside the mixing tank.
[0008] The stirring device comprises a driving unit, a stirring unit, a stirring unit and a discharging unit.
[0009] The driving unit comprises a driving motor, a transmission member and a stirring shaft. The driving motor is installed on the left side of the upper surface of the stirring tank. The transmission member is connected to the output end of the driving motor. The stirring shaft is fixedly connected to the bottom of the transmission member.
[0010] A further improvement is that a sealed bearing is installed in the center of the upper surface of the mixing tank, the mixing shaft is rotatably connected to the inside of the sealed bearing, and its bottom extends into the inside of the mixing tank, and the two bevel gears in the transmission part are driven by the driving motor to engage and rotate, thereby driving the mixing shaft to rotate inside the sealed bearing, thereby driving the mixing unit to mix and process the bentonite.
[0011] A further improvement is that the stirring unit includes stirring rods and a stirring auger. Two groups of stirring rods, each with three in a group, are fixedly connected to the upper and lower sides of the outer surface of the stirring shaft in a ring shape. The stirring auger is fixedly connected to the middle part of the stirring shaft. The stirring shaft drives the stirring rods and the stirring auger to rotate to stir the bentonite. The setting of the stirring auger flips the bentonite slurry from the bottom to the top, so that it is stirred more evenly.
[0012] A further improvement is that the stirring unit includes a sliding sleeve, a stirring plate, and a limiting scraper. The sliding sleeve is sleeved on the outer surface of the stirring rod. The six stirring plates are fixedly connected to the outer surface of the sliding sleeve in a ring shape. The limiting scraper is fixedly connected to the outer end of the stirring rod. When the stirring shaft rotates, the centrifugal force generated by it pushes the sliding sleeve to move outward. At the same time, the stirring plate hits the bentonite slurry, thereby further stirring the bentonite slurry and improving the stirring and mixing effect. The limiting scraper is set to scrape the bentonite slurry on the inner wall of the stirring tank for repeated stirring.
[0013] A further improvement is that the entire sleeve and the back of the limiting scraper are made of magnetic material, and the limiting scraper is tightly attached to the inner wall of the mixing tank. The outer surface of the stirring plate is equidistantly provided with spoiler holes. The setting of the spoiler holes performs spoiler cutting on the bentonite slurry to improve the mixing and stirring effect. When the sleeve slides to the back of the limiting scraper, a repulsive force is generated between the two, pushing the sleeve to reset, thereby realizing the repeated cyclic stirring of the bentonite slurry and further improving the mixing and stirring effect.
[0014] A further improvement is that the discharge unit includes a feed pipe, a discharge pipe, and an electric valve. The feed pipe is fixedly connected to the top right side of the mixing tank, and the discharge pipe is fixedly connected to the bottom center of the mixing tank. The two electric valves are respectively installed on the outer surfaces of the feed pipe and the discharge pipe. Bentonite and water are poured into the interior of the mixing tank through the feed pipe, and the finished product is discharged through the discharge pipe. The setting of the electric valve realizes the sealing of the mixing tank to avoid liquid seepage or dust overflow during mixing.
[0015] A further improvement is that a controller is installed above the front of the stirring tank, and the stirring device is electrically connected to the controller, and the operation of the device is controlled by the controller.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The municipal bored pile construction device drives the stirring rod and the stirring auger to rotate through the stirring shaft to stir the bentonite. The setting of the stirring auger flips the bentonite slurry from the bottom to the top, making it more evenly stirred.
[0018] 2. The municipal bored pile construction device, when the stirring shaft rotates, the centrifugal force it generates pushes the sliding sleeve to move outward, and at the same time, the stirring plate hits the bentonite slurry, thereby further stirring the bentonite slurry and improving the stirring and mixing effect. The setting of the limit scraper scrapes the bentonite slurry on the inner wall of the stirring tank and stirs it repeatedly.
[0019] 3. In the municipal bored pile construction device, when the sleeve slides to the back of the limit scraper, a repulsive force is generated between the two, pushing the sleeve to reset. The sleeve is then moved outward by the centrifugal force, thereby realizing the repeated stirring of the bentonite slurry and further improving the stirring and mixing effect.
