Description

Technical Field

[0001] The invention relates to the technical field of steel cage guide frames, in particular to a rock-embedded inclined pile steel cage guide frame and a construction method. Background Art

[0002] Rock-embedded inclined piles are a special type of deep foundation, embedded obliquely into the rock. The pile tip is embedded in moderately weathered or fresh bedrock, and the pile body is arranged at a certain slope, primarily to resist horizontal loads while also providing vertical bearing capacity.

[0003] The guide frame for the reinforcement cage of rock-embedded inclined piles is a support structure used to accurately place the reinforcement cage of rock-embedded inclined piles into the pile hole of the inclined pile. For example, the Chinese utility model patent with the announcement number CN205776225U discloses a guide frame device for lowering the reinforcement cage of an inclined hole rock-embedded pile, which includes a guide frame base, a reinforcement cage support and a hydraulic device. The lower end of the reinforcement cage support is hinged to the guide frame base, the middle part of the reinforcement cage support is hinged to one end of the hydraulic device, and the other end of the hydraulic device is fixed to the guide frame base. A pulley block is provided at the upper end of the reinforcement cage support, and the pulley block is connected to a winch provided on the guide frame base by a wire rope.

[0004] However, in actual use, the above technical solution still has the following shortcomings:

[0005] During the entire process of steel cage placement, the gravity of the guide frame and the steel cage will be directly transmitted to the hydraulic device, and the vibration generated during the steel cage placement process will also be transmitted to the hydraulic device. Under this stress state, not only will the sealing structure of the hydraulic device be severely worn, but the piston rod may even bend. Once the hydraulic device is damaged and leaks oil, the entire guide frame will directly fall over, causing a serious safety accident. Summary of the Invention

[0031] A construction method for a rock-embedded inclined pile reinforcement cage guide frame, based on the above-mentioned rock-embedded inclined pile reinforcement cage guide frame, comprises the following steps:

[0032] S1. Fix the chassis to the construction platform;

[0034] S3, start the second hydraulic cylinder, adjust the two guide shafts to the middle to the limit position, make the guide shaft and the intermediate shaft coaxial, and then close the second hydraulic cylinder;

[0035] S4, start the first hydraulic cylinder, adjust the inclination angle of the steel cage to a predetermined value, and then close the first hydraulic cylinder;

[0037] S6. Place the steel cage on the steel cage frame. At this time, the steel cage is coaxial with the pile hole. Then slowly place the steel cage into the pile hole.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

At this time, the guide shaft and the intermediate shaft are coaxial, that is, the intermediate shaft and the guide shaft are fixedly connected together. At this time, the telescopic movement of the first hydraulic cylinder will be converted into the rotational movement of the steel cage, thereby realizing the adjustment of the angle of the steel cage; on the other hand, when the push-pull component pushes the two guide shafts to the extreme position on both sides, the positioning cone is partially inserted into the inside of the tapered hole, and the space between the two ends of the intermediate shaft and the two guide shafts is In the state of active connection, the steel cage is supported by the side frame and maintained at a predetermined inclination angle. In this state, the vibration generated by the steel cage during the guidance of the steel cage will not be transmitted to the first hydraulic cylinder, thereby achieving effective protection for the first hydraulic cylinder and avoiding the occurrence of safety accidents. In addition, due to the conical structural design of the positioning cone, and when the push-pull component pushes the two guide shafts to the extreme positions on both sides, the positioning cone is still partially inserted into the inside of the conical hole, so it is only necessary to use the push-pull component to pull the two guide shafts to the middle to the extreme position to achieve the coaxial fixed connection between the guide shaft and the intermediate shaft.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0050] A rock-embedded inclined pile reinforcement cage guide frame includes a base frame 1, a reinforcement cage frame 2 and a first hydraulic cylinder 4. The bottom end of the reinforcement cage frame 2 is hinged to one end of the base frame 1 via a pivot 204. The end of the first hydraulic cylinder 4 away from the piston rod 401 is hinged to the base frame 1. The free end of the piston rod 401 is hinged to the reinforcement cage frame 2. The first hydraulic cylinder 4 is used to adjust the angle between the base frame 1 and the reinforcement cage frame 2.

[0051] The above are all prior art and will not be elaborated here.

[0052] Different from the prior art, the base frame 1 includes two I-beams 101 arranged in parallel and several connecting plates 102 fixedly connected between the two I-beams 101; the bottom surface of the connecting plate 102 is flush with the bottom surface of the I-beam 101, and the end of the first hydraulic cylinder 4 away from the piston rod 401 is hinged to one of the connecting plates 102. In actual construction, the base frame 1 is installed on the construction platform. Therefore, the end of the first hydraulic cylinder 4 away from the piston rod 401 is equivalent to being hinged to the construction platform.

[0053] The steel cage guide frame also includes side frames 3 fixedly arranged on both sides of the base frame 1; as can be seen from the figure, the side frames 3 are generally in the shape of a quarter circular plate, and the two side frames 3 are respectively arranged on both sides of the steel cage frame 2, sandwiching the steel cage frame 2 in the middle; the fixed connection method between the side frames 3 and the base frame 1 is not described here, for example, they can be fixed by welding.

[0054] The steel cage 2 includes a frame body and side support plates 203 arranged on both sides of the frame body, and mounting holes 2031 are opened on the side support plates 203; the shape of the side support plates 203 can be a triangular plate as shown in the figure, which can ensure that the steel cage 2 can adjust the angle within a larger range.

[0055] The frame includes several semicircles 201 and several long rods 202 fixedly connected to the inner side of the semicircle 201, and the side support plates 203 are fixedly connected to the semicircle 201; by arranging the long rods 202 on the inner side of the semicircle 201, the circular steel ring on the outer periphery of the steel cage can directly contact the long rods 202, avoiding the circular steel ring on the outer periphery of the steel cage from contacting the semicircle 201, thereby reducing the vibration during the placement of the steel cage.

[0056] The free end of the piston rod 401 is rotatably connected to the intermediate shaft 7 through the shaft sleeve 402. The intermediate shaft 7 can only rotate around its own axis and cannot move along its own axis. Positioning cones 8 are coaxially fixed at both axial ends of the intermediate shaft 7. As the direction gradually moves away from the intermediate shaft 7, the cross-sectional area of ​​the positioning cone 8 gradually decreases.

[0057] A guide sleeve 6 is fixedly installed inside the mounting hole 2031 , and a guide shaft 5 slides through the inside of the guide sleeve 6 . A tapered hole 501 is formed at one end of the guide shaft 5 close to the intermediate shaft 7 . The tapered hole 501 here is matched with the positioning cone 8 .

[0058] A push-pull component 9 is fixedly arranged between the two side support plates 203, and the push-pull component 9 is used to drive the guide shaft 5 to move along its own axis; specifically, when the push-pull component 9 pulls the two guide shafts 5 toward the middle to the extreme position, the outer conical surface of the positioning cone 8 fits with the inner conical surface of the conical hole 501, so that the guide shaft 5 and the intermediate shaft 7 are coaxially arranged; when the push-pull component 9 pushes the two guide shafts 5 to move to the extreme positions on both sides, the positioning cone 8 is partially inserted into the inside of the conical hole 501, and the end of the guide shaft 5 away from the intermediate shaft 7 is locked on the side frame 3.

[0059] In the above scheme, the positions of the two guide shafts 5 are adjusted by setting a push-pull component 9. On the one hand, when the push-pull component 9 pulls the two guide shafts 5 toward the middle to the extreme position, the outer conical surface of the positioning cone 8 fits with the inner conical surface of the tapered hole 501. At this time, the guide shaft 5 is coaxial with the intermediate shaft 7, that is, the intermediate shaft 7 and the guide shaft 5 are fixedly connected together. At this time, the telescopic movement of the first hydraulic cylinder 4 will be converted into the rotational movement of the steel cage 2, thereby realizing the adjustment of the angle of the steel cage 2; on the other hand, when the push-pull component 9 pushes the two guide shafts 5 to move to the extreme position on both sides, the positioning cone 8 is partially inserted into the inside of the tapered hole 501, and the two ends of the intermediate shaft 7 are now aligned with the two guide shafts. 5 is in a state of active connection, and the steel cage frame 2 is supported by the side frame 3 and maintained at a predetermined tilt angle. In this state, the vibration generated by the steel cage frame 2 in the process of guiding the steel cage will not be transmitted to the first hydraulic cylinder 4, thereby achieving effective protection for the first hydraulic cylinder 4 and avoiding the occurrence of safety accidents; in addition, due to the conical structure design of the positioning cone 8, and when the push-pull component 9 pushes the two guide shafts 5 to move to the extreme position on both sides, the positioning cone 8 is still partially inserted into the inside of the conical hole 501, it is only necessary to use the push-pull component 9 to pull the two guide shafts 5 toward the middle to the extreme position to achieve the coaxial fixed connection between the guide shaft 5 and the intermediate shaft 7.

[0060] An arcuate surface is provided on the side frame 3, and the center of the arcuate surface is located on the axis of the hinge shaft of the steel cage frame 2, that is, the center of the arcuate surface is located on the axis of the pivot 204; specifically, the side frame 3 includes a side splint 301 and an outer arc plate 302, and the two ends of the outer arc plate 302 are fixedly connected to the side splint 301, and an arc-shaped through hole 303 is formed between the side splint 301 and the outer arc plate 302; the arcuate surface is the inner arc surface of the arcuate through hole 303; a plurality of first teeth 304 are fixedly arranged at equal intervals on the arcuate surface; the second teeth 505 are provided at the end of the guide shaft 5 away from the intermediate shaft 7; when the push-pull component 9 pushes the two guide shafts 5 to move to the extreme position on both sides, the first teeth 304 and the second teeth 505 are engaged and locked.

[0061] The push-pull component 9 includes a mounting frame 901, a second hydraulic cylinder 902 and a hinged plate 905; wherein, the mounting frame 901 includes a horizontal plate 9011 and a vertical plate 9012 arranged perpendicularly to each other, the second hydraulic cylinder 902 is fixedly mounted on the horizontal plate 9011, the vertical plate 9012 is fixedly mounted on the side support plate 203, and two ribs 9013 are fixed between the horizontal plate 9011 and the vertical plate 9012, and the ribs 9013 are right-angled triangles.

[0062] The second hydraulic cylinder 902 is fixedly mounted on the side support plate 203 via a mounting bracket 901. The free end of the piston rod of the second hydraulic cylinder 902 is hinged to one end of the hinge plate 905 via a first hinge seat 903, and the guide shaft 5 is hinged to the other end of the hinge plate 905 via a second hinge seat 904. Thus, when the piston rod of the second hydraulic cylinder 902 extends outward, it pushes the two guide shafts 5 away from each other. When the piston rod of the second hydraulic cylinder 902 retracts inward, it pulls the two guide shafts 5 toward each other.

[0063] The guide shaft 5 includes a shaft body 502 and a tapered sleeve 503 coaxially fixed with the shaft body 502, and the tapered hole 501 is arranged inside the tapered sleeve 503; a locking block 504 is fixed at one end of the shaft body 502 away from the tapered sleeve 503, and the second tooth 505 is arranged on the locking block 504; and when the push-pull component 9 pushes the two guide shafts 5 to move to the extreme position on both sides, the locking block 504 contacts the outer arc plate 302; thereby, the outer arc plate 302 can be used to further limit the position of the guide shaft 5, thereby improving the stability of the guide shaft 5.

[0064] A guide plate 205 is hingedly installed on the side support plate 203 through a torsion spring hinge. The torsion spring hinge pushes the guide plate 205 away from one end of the side support plate 203 and presses it against the side frame 3. In this way, the two side frames 3 can achieve rough positioning of the steel cage, and then cooperate with the guide plate 205 to allow the steel cage to be quickly and accurately placed on the steel cage frame 2.

[0065] A construction method for a rock-embedded inclined pile reinforcement cage guide frame, based on the above-mentioned rock-embedded inclined pile reinforcement cage guide frame, comprises the following steps:

[0066] S1. Fix the chassis 1 to the construction platform;

[0067] S2, install the steel cage 2 and the first hydraulic cylinder 4 on the base frame 1;

[0068] S3. Start the second hydraulic cylinder 902, adjust the two guide shafts 5 to move closer to the middle to the limit position, so that the guide shafts 5 and the intermediate shaft 7 are coaxial and fixedly connected, and then close the second hydraulic cylinder 902;

[0069] S4, start the first hydraulic cylinder 4, adjust the inclination angle of the steel cage 2 to a predetermined value, and then close the first hydraulic cylinder 4;

[0070] S5. Start the second hydraulic cylinder 902 again, adjust the two guide shafts 5 to move to the extreme positions on both sides, so that the positioning cone 8 is only partially inserted into the tapered hole 501, and the first teeth 304 and the second teeth 505 are engaged and locked, and then close the second hydraulic cylinder 902; at this time, the steel cage 2 is fully supported by the two side frames 3;

[0071] S6. Place the steel cage on the steel cage frame 2. At this time, the steel cage is coaxial with the pile hole. Then, slowly place the steel cage into the pile hole.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
