The utility model can conveniently realize the cleaning operation of the drill rod and avoid the occurrence of potential safety hazards.
Description
Technical Field
The utility model belongs to the technical field of building construction, and particularly relates to a drill rod dirt cleaning structure for construction of a long spiral filling pile.
Background
When the construction of the long spiral filling pile is carried out, a long spiral drilling machine is adopted to drill holes in advance to a preset depth; when the spiral drill rod is lifted out of the soil, a large amount of soil is clamped in the gaps of the spiral blades, the soil is not easy to separate when the screw rod is lifted, cleaning is realized by subsequent hammering or shoveling and cutting by staff, cleaning is time-consuming and labor-consuming, and the soil blocks which are separated individually often occur at high positions and easily damage ground staff.
Disclosure of Invention
The utility model aims to provide a drill rod dirt-removing structure for construction of a long spiral filling pile; the spiral drill rod is used for solving the problem that soil is not easy to clean when the spiral drill rod is carried.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a long spiral bored concrete pile construction is with drilling rod structure of decontaminating, includes the fender ring of establishing on long spiral drilling machine, its characterized in that still includes detachable baffle that sets up on the fender ring outer circumference, establishes the mud scraping device on the baffle.
Further, the mud scraping device comprises a scraping rod penetrating through the guide plate and hinged to the guide plate through a support, and a balancing weight arranged at the lower end of the scraping rod; the top end of the scraping rod is processed into a bent hook shape.
Further, two sleeves are arranged on the outer circumference of the baffle ring at intervals, inserting rods corresponding to the sleeves are arranged on the lower side of the guide plate, and the inserting rods are matched with the sleeves to realize detachable connection of the guide plate and the baffle ring.
Further, the deflector is semi-annular in top view, and is inclined obliquely downwards relative to the baffle ring.
The beneficial effects of the utility model are as follows:
the scraping rod acts on the space between the blades of the spiral drill rod, and the screw rod reversely rotates when being lifted, so that the scraping rod is promoted to destroy the inherent stability of soil, the soil is further quickly dropped off and scattered to the periphery of the spiral drill rod through the guide plate, the follow-up manual cleaning is not needed, and the safety risk caused by the drop of the soil at high positions is avoided; the detachable connection structure of the guide plate and the baffle ring increases the convenience of application.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic diagram of another embodiment of the present utility model;
fig. 3 is a schematic top view of the deflector and the scraper bar according to the present utility model.
Wherein, 1-baffle ring; 2-a deflector; 3-scraping rod; 4-balancing weight; 5-sleeve; and 6-inserting the rod.
Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, a drill rod dirt cleaning structure for construction of a long spiral bored pile; the dirt cleaning structure comprises a baffle ring 1 arranged on a long spiral drilling machine, wherein the baffle ring 1 is sleeved on the outer side of a spiral drill rod which is vertically arranged. The dirt cleaning structure further comprises a guide plate 2 detachably arranged on the outer circumference of the baffle ring 1 and a mud scraping device arranged on the guide plate 2.
The deflector 2 is used for realizing the dispersion of earth, and the condition of backfilling appears in the earth accumulation in drilling position too near. The deflector 2 is semi-annular in plan view, and the deflector 2 is inclined obliquely downwards relative to the baffle ring 1, so that soil blocks can be promoted to slide down.
The mud scraping device comprises a scraping rod 3 and a balancing weight 4. The top end of the scraping rod 3 is processed into a hook shape, so that the scraping rod is beneficial to being inserted into a soil layer, the soil blocks are disturbed, and the soil blocks are promoted to fall off rapidly; the scraping rod 3 is in a bending shape; the scraping rod 3 penetrates through the guide plate 2, a support is arranged on the guide plate 2, a pin shaft is inserted in the middle of the scraping rod 3, the scraping rod 3 is hinged to the support through cooperation of the pin shaft and the support, and the balancing weight 4 is connected to the bottom of the scraping rod 3. The scraper bar 3 has a moving swing space when acting on the soil blocks, which can further promote the disturbance of the soil blocks.
The baffle ring 1 is provided with two sleeves 5 at intervals on the outer circumference, the lower side of the guide plate 2 is provided with a inserted link 6 corresponding to the sleeves 5, the inserted link 6 is inserted into the sleeves 5 to realize the connection and fixation of the guide plate 2 and the baffle ring 1, and the structure also has the characteristics of detachability and convenient maintenance.
The application method and the working principle of the utility model are as follows:
when the spiral drill rod on the long spiral drilling machine is lifted, the spiral drill rod is lifted in a rotating state; the scraping rod 3 and the end part of the bent hook shape are inserted into the soil layer clamped by the blades in the lifting process, and the soil layer is scraped or pulled, so that the soil layer is disturbed to change the inherent consolidation state, and then automatically falls off and slides down through the guide plate 2. In the soil scraping process, due to the hinged connection of the scraping rod 3 and the matching action of the balancing weight 4, the end part of the scraping rod 3 is enabled to have a certain swinging function when scraping soil, the actual action position of the scraping rod 3 can be changed, and the soil falling is further promoted. The spiral drill rod cleaning device is simple in overall structural design, convenient to process and manufacture and capable of achieving an automatic cleaning function of the spiral drill rod.
