Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a positioning device suitable for built-in concrete piles and maintenance equipment thereof. Background Art

[0002] Prestressed pipe piles are widely welcomed by the construction market for their factory-produced pile bodies, stable and reliable quality, convenient and fast construction, high bearing capacity and low cost. Since their development, they have developed rapidly and have been widely used. However, with the development of social economy, the continuous renewal of building heights, the continuous deepening of underground space, the needs of urban development and the improvement of people's environmental awareness, the application space of traditional hammering or static pressure prestressed pipe pile construction is gradually shrinking. In order to fully continue the advantages of prefabricated pipe piles, a "drilling pile planting" construction method has been derived in the industry, namely the "drilling-pouring concrete-pile planting-pile sinking-pile formation" construction process.

[0003] For example, a new type of superimposed cast-in-place pile suitable for karst landforms and its construction method disclosed in Chinese patent CN111719551A includes an external steel casing, a drill bottom is fixedly installed at the bottom end of the external steel casing, and a plurality of grouting holes are opened on the outer surface of the drill bottom, and the plurality of grouting holes are arranged in a ring. The present invention sets a drill bottom, a drill rod, an external steel casing and an internal pile body. When installing the cast-in-place pile, it is necessary to drill holes through the drill bottom at the bottom end. During the rotation process, the drill rod at the bottom end of the drill bottom will crush the stones. The drill rod is made of conical stainless steel material, which can more conveniently crush the obstructing stones and facilitate the installation of the cast-in-place pile. The outer surface of the internal pile body is sleeved with an external steel casing, and the external steel casing is fixed to the internal pile body through a steel casing reinforcement ring, so that the internal pile body can be better protected to avoid damage during use, thereby increasing the service life of the cast-in-place pile.

[0004] However, in actual application, it has the following defects:

[0005] First, during the application of the bored pile construction method, it is difficult to accurately control the wall protection, pile center positioning and pile body verticality after drilling;

[0006] Secondly, there are often problems such as the collapse of the borehole wall, large displacement of the pile center, non-centering, poor verticality of the pile body, insufficient compaction of the poured concrete, and the presence of cavities;

[0007] Third, in water-rich environments with complex foundation soil, additional water-stopping and wall protection and collapse prevention measures need to be implemented after drilling, which increases costs and extends the construction period. After pouring concrete, the pipe pile compaction effect is poor and the pile formation efficiency is low, which will lead to delays in subsequent construction. Utility Model Content

[0146] Working principle and usage:

[0147] Production, use and maintenance process of positioning device:

[0148] Processing and manufacturing of double sleeve auxiliary pile planting device (i.e. internal pile positioning device) → construction preparation → precast pile bottom sealing → positioning and setting out → pre-drilling → driving in external sleeve 601 and calibration → rotary drilling to form a hole → pouring fine stone concrete → installing internal sleeve 602 → implanting precast piles → dismantling of double sleeve auxiliary device (pulling out internal sleeve 602 and external sleeve 601 in sequence) → sealing of precast pile ends → maintenance and turnover of double sleeve auxiliary pile planting device → single pile inspection → acceptance.

[0149] The maintenance process is as follows:

[0150] The first step is loading:

[0151] Place the tube body (internal sleeve 602, external sleeve 601) above the "U"-shaped positioning plate 210, press the fixed switch, and the PLC controller outputs a signal to the screw lift 209.

[0152] The screw lift 209 drives the "U"-shaped positioning plate 210 to move upward, and the "U"-shaped positioning plate 210 drives the tube body to move upward in an orderly manner (by pressing a fixed switch number of times).

[0153] Press the positioning switch 1 and the positioning switch 2, and the PLC controller outputs a signal to the push rod motor 1 202. The push rod motor 1 202 drives the chuck 203 and the auxiliary fixing structure to approach each other in an orderly manner, and the staff performs fine adjustment through the adjustable fixing structure.

[0154] After that, long press the positioning switch 1 and the positioning switch 2, the distance sensor module 1 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the chuck 203, the electric lifting device 1, and the push rod motor 3 208. The chuck 203 and the electric lifting device 1 are started first, and then the push rod motor 3 208 is started, so as to realize the rapid fixation of the pipe body.

[0159] The pump and the solenoid valve are started intermittently, and the cleaning roller shaft 1 302 and the cleaning roller shaft 2 304 are cleaned regularly.

[0160] The electric telescopic rod three 303 drives the cleaning roller shaft two 304 to move downward, and the servo motor one 204 rotates in an orderly manner to achieve cleaning of the middle part of the tube body.

[0161] The electric telescopic rod four delays and drives the cleaning roller shaft three 306 to move downward, and the servo motor two 307 drives the cleaning roller shaft three 306 to rotate in an orderly manner; the screw stepper motor one 305 drives the cleaning roller shaft three 306 to move forward and backward to clean both ends of the tube body.

[0162] The electric telescopic rod 2 301 drives the cleaning roller 1 302 to enter the inner wall of the pipe in an orderly manner, and the servo motor 1 204 rotates in an orderly manner to clean the inner wall of the pipe. The staff can adjust the position of the nut seat of the linear motor 201 according to the diameter of the pipe to improve the cleaning effect.

[0163] After the cleaning is completed, the linear motor 201 delays and drives the tube body to move below the electric telescopic rod five 401, and the distance sensor module three outputs a signal to the PLC controller, and the PLC controller outputs a signal to the electric telescopic rod five 401, the electric valve, the electric telescopic rod six 404, and the electric telescopic rod seven.

[0164] The electric valve is started, oil outlet head 1, oil outlet head 2 and oil outlet head 3 are opened, maintenance oil is added to oiling roller shaft 1 402 and oiling roller shaft 2 405, electric telescopic rod 6 404 drives the flexible roller shaft ring to approach the pipe body; servo motor 1 204 rotates in an orderly manner to realize oiling of the middle part of the pipe body.

[0165] Afterwards, the electric telescopic rod seven delays and drives the oiling roller shaft three 407 to move downward; the screw stepper motor two 406 drives the oiling roller shaft three 407 to move forward and backward, and the servo motor one 204 rotates in an orderly manner to achieve oiling of both ends of the pipe body.
