Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a hydraulic positioning tool for the base structure of a cup. Background Technology

[0002] The cup-shaped foundation structure plays a crucial role in building engineering, especially in steel structure buildings. It not only needs to bear the weight of the superstructure, but also must provide sufficient stability and precise positioning capabilities to ensure the structural integrity and extend its service life.

[0003] Each cup-shaped foundation requires a precise design and implementation process. The rapid and accurate positioning and adjustment of the steel structure are crucial for ensuring project quality, shortening the construction period, and reducing costs. Technical requirements: Each cup-shaped foundation must ensure consistency in dimensional accuracy and load-bearing capacity during construction to guarantee the long-term stability and safety of the building structure. Steel structure components need to be precisely aligned with the pre-designed cup-shaped foundation structure to ensure the stability and safety of the entire building. However, due to unavoidable errors during transportation and hoisting, as well as the complex and variable site environment, the cup-shaped foundation structure often cannot meet the needs for rapid adjustment, leading to construction delays and increased costs. In this invention, the traditional through-hole cup-shaped foundation is changed to a countersunk hole design.

[0004] During the adjustment process, a hydraulic component similar to a jack is used to position and adjust the steel structure within the cup opening. Existing construction equipment typically uses hydraulic components with a hydraulic power source, i.e., a hydraulic pump, and is generally driven by an internal combustion engine, making the entire device relatively large. Furthermore, common household hydraulic jacks, with their oil reservoir located outside the piston cylinder, generally cannot be used horizontally, while the steel structure and cup opening position adjustment is for horizontal adjustment. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a hydraulic positioning fixture for the base structure of a cup, comprising a base. Multi-stage hydraulic cylinders are horizontally fixedly connected to both sides of the base. A valve module, a small hydraulic cylinder, and an oil tank are disposed between two of the multi-stage hydraulic cylinders. The valve module is equipped with a first check valve, a second check valve, a third check valve, and a fourth check valve. By connecting two multi-stage hydraulic cylinders in parallel, a greater supporting force can be provided. Furthermore, the multi-stage hydraulic cylinder configuration increases the supporting length.

[0006] Two multi-stage hydraulic cylinders are connected in parallel and to a smaller hydraulic cylinder. A first check valve is installed on the connecting pipeline, directing hydraulic oil to the multi-stage hydraulic cylinder. The smaller hydraulic cylinder is connected to an oil tank, and a third check valve is installed on the connecting pipeline, directing hydraulic oil to the smaller hydraulic cylinder. When the smaller hydraulic cylinder operates, it draws hydraulic oil from the oil tank and forces it into the multi-stage hydraulic cylinder.

[0007] Preferably, the multi-stage hydraulic cylinder is connected to the oil tank, and a second check valve is installed on the connecting pipeline to the multi-stage hydraulic cylinder. During operation, the output end of the multi-stage hydraulic cylinder can be pulled out to a suitable length. During the pulling process, a negative pressure is generated inside the multi-stage hydraulic cylinder. At this time, the second check valve opens under the action of the negative pressure, and the hydraulic oil in the oil tank enters the multi-stage hydraulic cylinder.

[0008] Preferably, the multi-stage hydraulic cylinder is connected to the oil tank, and a valve is installed on the connecting pipeline. When the valve is opened, the multi-stage hydraulic cylinder and the oil tank are connected. By pressing down on the end of the multi-stage hydraulic cylinder, the hydraulic oil in the multi-stage hydraulic cylinder is forced back into the oil tank, at which point the output end of the multi-stage hydraulic cylinder retracts.

[0009] Preferably, the output ends of both multi-stage hydraulic cylinders are fixedly connected to support members. The support members ensure that the two multi-stage hydraulic cylinders maintain the same extension length and that the output ends of the two multi-stage hydraulic cylinders are subjected to consistent forces.

[0010] Preferably, a support frame is fixedly connected to the side wall of the multi-stage hydraulic cylinder. When the tooling is placed horizontally, the support frame rests on a horizontal support surface.

[0011] Preferably, the first, second, and third check valves have identical structures, each with a pre-set channel within the valve module, including a ball. A spring is positioned below the ball, and a limit ring is located at the lower end of the spring. The side wall of the limit ring is threaded into the inner wall of the channel. Under the action of the spring, the ball always blocks the channel, thus ensuring normal operation regardless of its working posture.

[0012] The beneficial effects of this utility model are as follows: 1. Meets the needs of construction at the cup rim, can be used independently, and makes construction more convenient; 2. To overcome the shortcomings of traditional jacks that cannot be used horizontally, a spring is installed to hold the ball in place, ensuring the closure of the one-way valve in any position while simultaneously meeting normal oil supply requirements; 3. Equipped with a second check valve, the extension length of the multi-stage hydraulic cylinder can be pre-adjusted to match the working space and improve work efficiency; 4. Dual-cylinder configuration to meet the needs of high support force and improve applicable scenarios. Attached Figure Description

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0016] like Figures 1 to 4 As shown, a hydraulic positioning fixture for the base structure of a cup includes a base 1, which is a shell with a recessed side. The base 1 contains connecting pipes and auxiliary support blocks. Multi-stage hydraulic cylinders 4 are horizontally fixed to both sides of the base 1. A valve module 2, a small hydraulic cylinder 3, and an oil tank 5 are located between two multi-stage hydraulic cylinders 4. The valve module 2 is connected to the oil tank 5. The valve module 2 is equipped with a first check valve 8, a second check valve 9, a valve 10, and a third check valve 11. According to... P=F / S, pressure P , force F Area of ​​action S The greater the ratio of the working area between the multi-stage hydraulic cylinder 4 and the small hydraulic cylinder 3, the greater the force exerted by the multi-stage hydraulic cylinder 4. In this case, using two multi-stage hydraulic cylinders 4 undoubtedly increases the ratio of the working area between the multi-stage hydraulic cylinder 4 and the small hydraulic cylinder 3, thereby improving the working support strength.

[0017] Furthermore, the structure of the multi-stage hydraulic cylinder 4 increases the length of the support.

[0018] Two multi-stage hydraulic cylinders 4 are connected in parallel and connected to a small hydraulic cylinder 3. A first check valve 8 is installed on the connecting pipeline to flow to the multi-stage hydraulic cylinder 4, meaning that hydraulic oil can only flow into the multi-stage hydraulic cylinder 4 from the small hydraulic cylinder 3. The small hydraulic cylinder 3 is connected to an oil tank 5, and a third check valve 11 is installed on the connecting pipeline to flow to the small hydraulic cylinder 3, meaning that hydraulic oil in the oil tank 5 can only enter the small hydraulic cylinder 3.

[0019] The specific working principle is as follows: When the output end of the small hydraulic cylinder 3 is pulled out, the inside of the small hydraulic cylinder 3 is under negative pressure, the first one-way valve 8 is closed, the third one-way valve 11 is opened, and the hydraulic oil in the oil tank 5 is drawn into the small hydraulic cylinder 3. When the output end of the small hydraulic cylinder 3 is pushed back into the interior, the inside of the small hydraulic cylinder 3 is under positive pressure, the first one-way valve 8 is opened, the third one-way valve 11 is closed, and the hydraulic oil is pushed into the multi-stage hydraulic cylinder 4, thereby pushing out the output end of the multi-stage hydraulic cylinder 4.

[0020] The multi-stage hydraulic cylinder 4 is connected to the oil tank 5, and a second check valve 9 is installed on the connected pipeline to direct the flow to the multi-stage hydraulic cylinder 4. When this fixture is in use, the output end of the multi-stage hydraulic cylinder 4 can be pulled out to a suitable length in advance. During this process, the second check valve 9 is in the open state. The purpose of this setting is to match the length of the working space, thereby reducing the length of the multi-stage hydraulic cylinder 4 output end that is pushed out by the small hydraulic cylinder 3, thus improving the efficiency of the operation.

[0021] The multi-stage hydraulic cylinder 4 is connected to the oil tank 5, and a valve 10 is installed on the connected pipeline. After the operation is completed, the valve 10 is opened and the end of the multi-stage hydraulic cylinder 4 is pressed to send the hydraulic oil inside the multi-stage hydraulic cylinder 4 into the oil tank 5.

[0022] The output ends of both multi-stage hydraulic cylinders 4 are fixedly connected to support members 7. The support members 7 make the output ends of the two multi-stage hydraulic cylinders 4 a single unit, thereby ensuring that the force on the two multi-stage hydraulic cylinders 4 is consistent. In addition, the support members 7 can also be used as handles when picking up the device. It should be noted that a fastener is provided between the support members 7 and the oil tank 5 to prevent the output ends of the multi-stage hydraulic cylinders 4 from protruding during the lifting process.

[0023] The side wall of the multi-stage hydraulic cylinder 4 is fixedly connected to a support frame 6. The support frame 6 is pre-supported on the water surface support surface when the tooling is used.

[0024] The first check valve 8, the second check valve 9, and the third check valve 11 have identical structures, all featuring a pre-set channel within the valve module 2. Each valve includes a ball 14, with a spring 13 positioned below it. A limit ring 12 is located at the lower end of the spring 13, and a through hole in the center of the limit ring 12 allows hydraulic oil to pass through. This through hole has a regular hexagonal cross-section, facilitating adjustment of the spring 13's preload by rotating the limit ring 12 with a wrench. The limit ring 12's sidewall is threaded into the inner wall of the channel. This spring 13 structure ensures that the ball 14 always blocks the channel, guaranteeing the tooling's usability even in various orientations.

[0025] It should be noted that the oil inlet and outlet of the oil tank 5 are located in a sheltered position and close to the valve module 2, so that the fixture can be used normally whether it is horizontal or vertical.

[0026] When using, such as Figure 4 If so, the cup opening is a rectangular countersunk hole with a steel structural column inserted in the middle. This is where the relative position between the steel structural column and the cup opening is adjusted. At this time, the tooling is set on the upper part of the cup opening, with one end abutting against the inner wall of the cup opening and the other end abutting against the side wall of the column. After the position is adjusted, a wedge can be inserted between the structural column and the cup opening. If necessary, the wedge can be welded to the steel structural column.
