Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for pile foundation construction, in particular to an auxiliary positioning device for pile foundation construction. Background Art

[0002] The pile foundation consists of piles and pile caps. The pile construction method is divided into two categories: prefabricated piles and cast-in-place piles. In addition to the engineering geological conditions, the selection of the pile driving method must also consider the type, section, length, site environment and design requirements of the pile. With the development of the construction industry, the pile length and diameter are getting larger and larger, and the pile foundation construction has developed from stone ramming wooden piles to drop hammer construction. In order to meet the needs of large-scale pile foundation projects, the pile foundation construction technology must not only increase the hammer weight and improve the lifting and hoisting operation process, but also reduce vibration noise and environmental pollution.

[0003] For example, a construction engineering building foundation pile construction equipment with patent announcement number CN217758794U can make the metal slag suction pipe move and retract arbitrarily at the bottom of the pile hole through an electric cross slide and an electric push rod, and the slag blocks can be dispersed by a high-pressure nozzle to facilitate the cleaning of the slag suction head. The slag blocks and sewage can be contained in the bucket through a containing bucket and treated uniformly at the end of cleaning. The slag blocks at the bottom of the pile hole can be cleaned away by the metal slag suction pipe and the slag suction head, so as to avoid the angle and height of the foundation pile being affected by the scattered slag blocks in the pile hole, thereby avoiding a great impact on the construction of the building engineering.

[0004] Although the above equipment can clean up the slag blocks at the bottom of the pile hole through the metal slag suction pipe and slag suction head, avoiding the angle and height of the foundation pile being affected by the scattered slag blocks in the pile hole, and avoiding a great impact on the construction of the building project, the positioning of the prefabricated piles in the pile foundation construction mainly relies on manual labor and experience, with low positioning accuracy and prone to tilting problems, which affects the construction quality and efficiency. To this end, we propose an auxiliary positioning device for pile foundation construction. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary positioning device for pile foundation construction to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary positioning device for pile foundation construction, comprising:

[0007] The auxiliary positioning device for pile foundation construction is composed of a bottom plate, an adjustment mechanism, and a positioning mechanism;

[0008] The adjusting mechanism is arranged at the top of the four sides of the bottom plate and is used to adjust the height and distance of the positioning mechanism;

[0009] The positioning mechanism is arranged at one end of the adjusting mechanism and is used for auxiliary positioning during the pile foundation construction process.

[0010] As a specific solution in the technical solution of this application, the adjustment mechanism includes:

[0011] The screw rod is installed around the top of the bottom plate, and support plates are installed on the left and right sides of the screw rod. The inner sides of the top of the support plates are connected through fixed blocks, and a rotating wheel is installed on the outer wall of the top of the screw rod.

[0012] As a specific solution in the technical solution of this application, the top end of the screw rod passes through the fixed block and extends to the outside. The rotating wheel is located at the top end of the fixed block. A moving part is installed on the outer wall of the screw rod, and an electric push rod is installed at one end of the moving part.

[0013] As a specific solution in the technical solution of the present application, a fixed cone rod is installed on the inner side of the base plate, the bottom end of the fixed cone rod passes through the outer wall of the base plate, and a rotating wheel is installed on the outer wall of the top end of the fixed cone rod; a cross fixing plate is installed on one side of the fixed block, the cross fixing plate is provided with a circular hole, and the base plate is provided with a square hole, and the center of the circular hole is directly opposite to the center of the square hole.

[0014] As a specific solution in the technical solution of this application, the positioning mechanism includes:

[0015] A fixed square cylinder is installed at the output end of the electric push rod, and a compression rod is fixedly installed at the bottom inner end of the fixed square cylinder. A limit plate is fixedly installed at the other end of the compression rod on the front and rear adjustment mechanisms, and an arc plate is fixedly installed at the other end of the compression rod on the left and right adjustment mechanisms. A movable sleeve is installed on the same side of the compression rod on the arc plate and the limit plate.

[0016] As a specific solution in the technical solution of the present application, one end of the movable sleeve is located on the inner side of the fixed square tube, and a square groove is arranged around the inner surface of the fixed square tube. A sliding rod is installed around one end of the outer surface of the movable sleeve, and the sliding rod is located on the inner side of the square groove. A connecting spring is installed on the outer wall of the compression rod, and the connecting spring is located on the inner side of the fixed square tube and the movable sleeve.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The auxiliary positioning device for pile foundation construction can fix the device by setting a fixed cone rod, which is convenient for implementing the cross-cross method bolting. By adjusting each fixed cone rod, it can adapt to different working surfaces. By rotating the rotating wheel to adjust the moving part to different heights, the entire drill bit assembly can be adjusted to calibrate with the center position of the drill hole, the deviation can be controlled, and the utilization rate of the device is improved.

[0019] At the same time, the precast pile can be positioned by driving the arc plate or the limit plate to translate through the electric push rod. When the bottom end of the movable sleeve coincides with the inner bottom end of the fixed square tube, part of the thrust provided by the electric push rod is removed. At this time, the elastic force of the spring will still prompt the arc plate to position the precast pile, but the precast pile is not in a locked state and can be lifted and lowered, and can adapt to precast piles of different diameters, thereby improving the efficiency and accuracy of the device construction.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] During the pile foundation construction process, a positioning device is required. The positioning device provided by the utility model is specifically used for auxiliary positioning operations during the pile foundation construction process. During the use of this device for positioning operations, it is necessary to ensure in advance that the auxiliary positioning device has been correctly installed near the pile foundation that needs to be measured or positioned. Before actual use, the auxiliary positioning device needs to be calibrated. According to specific measurement requirements, the measurement parameters of the auxiliary positioning device are set. According to the specific location and environmental conditions of the pile foundation, a suitable positioning method is selected to ensure a clear field of view, no obstructions or interferences, and no extreme weather or environmental conditions that affect the measurement accuracy. Before performing any measurement operation, ensure the safety of the working area, so that the auxiliary positioning device can be effectively used to position the pile foundation to ensure the accuracy and reliability of construction and engineering measurements.

[0027] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an auxiliary positioning device for pile foundation construction, comprising:

[0028] The auxiliary positioning device for pile foundation construction is composed of a base plate 4, an adjustment mechanism 5, and a positioning mechanism 6;

[0029] The adjusting mechanism 5 is arranged at the top of the four sides of the bottom plate 4 and is used to adjust the height and distance of the positioning mechanism 6;

[0030] The positioning mechanism 6 is arranged at one end of the adjusting mechanism 5 and is used for auxiliary positioning during the pile foundation construction process.

[0031] The regulating mechanism 5 comprises:

[0032] The screw rod 501 is installed around the top of the bottom plate 4, and support plates 502 are installed on the left and right sides of the screw rod 501. The inner sides of the tops of the support plates 502 are connected through fixed blocks 505, and the outer wall of the top of the screw rod 501 is installed with a rotating wheel 2.

[0033] The top of the screw rod 501 passes through the fixed block 505 and extends to the outside. The rotating wheel 2 is located at the top of the fixed block 505. A moving part 503 is installed on the outer wall of the screw rod 501. An electric push rod 504 is installed at one end of the moving part 503.

[0034] like Figure 3 As shown, it should be noted that: by rotating the rotating wheel 2, the screw 501 can be driven to rotate, and the screw 501 can drive the moving part 503 to rise and fall during rotation. The device is provided with a total of four groups of adjustment mechanisms 5, and each group of adjustment mechanisms 5 can act independently. Therefore, after the installation of the base plate 4 is completed, if the device is tilted, the rotating wheel 2 on each group of adjustment mechanisms 5 can be adjusted. By rotating different parameters of the rotating wheel 2, the positioning mechanism 6 at one end of the electric push rod 504 can be adjusted to different heights, thereby ensuring that no error will occur during the entire process of pile foundation construction.

[0035] A fixed cone rod 1 is installed on the inner side around the bottom plate 4, the bottom end of the fixed cone rod 1 passes through the outer wall of the bottom plate 4, and a rotating wheel 2 is installed on the outer wall of the top end of the fixed cone rod 1; a cross fixing plate 7 is installed on one side of the fixed block 505, the cross fixing plate 7 is provided with a circular hole, and the bottom plate 4 is provided with a square hole, and the center of the circular hole is right at the center of the square hole.

[0036] like Figure 1 As shown, it should be noted that: by using a hammer to hit the fixed cone rod 1, the fixed cone rod 1 can be immersed in the ground required for installation. When the installation environment is uneven, the depth of each fixed cone rod 1 inserted into the ground can be adjusted to adjust the horizontality of the base plate 4. The fixed cone rod 1 is not completely immersed in the ground, and a section needs to be exposed. The exposed part is tied with a cross-shaped stake by a rope to determine the drilling position. When drilling is to be performed, the positioning mechanism 6 is used to clamp the drill bit assembly, and the positioning mechanism 6 is used to adjust the drill bit assembly and align it with the drilling center position determined by the cross-shaped method to control the deviation within 2 cm.

[0037] The positioning mechanism 6 comprises:

[0038] A fixed square cylinder 607 is installed at the output end of the electric push rod 504, and a compression rod 603 is fixedly installed at the bottom inner end of the fixed square cylinder 607. The other end of the compression rod 603 on the front and rear adjustment mechanisms 5 is fixedly installed with a limit plate 601, and the other end of the compression rod 603 on the left and right adjustment mechanisms 5 is fixedly installed with an arc plate 602. A movable sleeve 604 is installed on the same side of the compression rod 603 on the arc plate 602 and the limit plate 601.

[0039] One end of the movable sleeve 604 is located on the inner side of the fixed square cylinder 607, and square grooves 605 are arranged around the inner surface of the fixed square cylinder 607. A sliding rod 608 is installed around one end of the outer surface of the movable sleeve 604, and the sliding rod 608 is located on the inner side of the square groove 605. A connecting spring 606 is installed on the outer wall of the compression rod 603, and the connecting spring 606 is located on the inner side of the fixed square cylinder 607 and the movable sleeve 604.

[0040] like Figure 4As shown, it should be noted that: the electric push rod 504 drives the limit plate 601 to translate. When the limit plate 601 moves to the precast pile, it continues to translate forward. The limit plate 601 will move in the square groove 605 through the sliding rod 608 on the outer surface of the movable sleeve 604, thereby driving the compression rod 603 to contract. During the contraction of the compression rod 603, the connecting spring 606 is simultaneously compressed. When the bottom end of the movable sleeve 604 abuts against the inner bottom end of the fixed square tube 607, Stop the electric push rod 504 from working. At this time, the limit plate 601 will fix the precast pile, and the arc plate 602 will perform the above-mentioned synchronous operation. The arc plate 602 will clamp the precast pile. The limit plate 601 and the arc plate 602 will operate independently without affecting each other. Therefore, the corresponding drilling position of the precast pile can be adjusted by adjusting the extension lengths of the limit plate 601 and the arc plate 602. After alignment, the electric push rod 504 is slightly loosened to facilitate the movement of the precast pile inside the positioning mechanism 6.

[0041] In summary, the auxiliary positioning device for pile foundation construction can adapt to different working environments through the coordination setting between the adjustment mechanism 5 and the positioning mechanism 6, and adjust the orientation of the precast piles, limit the precast piles during their installation, thereby improving the positioning accuracy of the pile foundation and improving the construction quality and efficiency.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
