Description

Technical Field

[0001] This utility model relates to the field of jacks, and in particular to a multi-axis parallel jack structure for foundation pit servo support. Background Technology

[0002] A jack is a simple mechanical device used to lift heavy objects. It is widely used in automotive repair, construction, and other applications requiring temporary support or lifting of heavy loads. They are primarily operated manually or hydraulically and come in various types and designs to suit different needs.

[0003] Traditional jacks are usually single-axis type. During use, it is necessary to ensure that the jack is located in the exact center of the component, otherwise it is easy to cause eccentric load problems. At the same time, in deep foundation pit projects in soft soil layers, near sensitive buildings, densely populated urban areas, and under dynamic load environments, traditional single-axis jacks will tilt, affecting the lifting of the component, which needs to be improved. Utility Model Content

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting up multi-axis jacks and cooperating with ball joint connected brackets, the overall direction control of the composite jacks is achieved by independently adjusting the force of each axis, forming a composite action axis with dynamically adjustable direction, thereby maintaining the stability of the horizontal direction of the force. The four-axis parallel structure realizes the vector synthesis of force.

[0019] 2. By setting up pressure sensors, displacement sensors, and tilt sensors, multi-data fusion is achieved to form a multi-dimensional feedback system, which is conducive to realizing four-axis coordinated control, achieving dynamic self-balancing adjustment, and solving the off-center load problem;

[0020] 3. By setting a self-locking mechanism, the position can be manually locked in the event of a power outage or malfunction, ensuring the stability and safety of the entire jack structure during use. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, a multi-axis parallel jack structure for servo support in a foundation pit includes a base 1, multiple hydraulic jacks 2, end caps 3, and support 4.

[0027] like Figure 1 , Figure 2 As shown, the base 1 is arranged in a horizontal plate shape, and multiple hydraulic jacks 2 are orthogonally symmetrical and vertically arranged on the base 1 with a spatial angle of 90°±0.5°, thereby ensuring that the resultant force vector can cover the target adjustment range.

[0028] like Figure 1 , Figure 2 As shown, the hydraulic jack 2 includes a pump body 21 and a piston rod 22. A groove 11 is provided on the base 1, and the lower end of the pump body 21 is threaded into the groove 11 to realize the quick installation and fixation of the hydraulic jack 2.

[0029] like Figure 1 , Figure 2 As shown, the piston rod 22 is vertically slidably connected to the pump body 21, the end 3 is vertically set at the upper end of the piston rod 22, and the support 4 is ball-jointed on the end 3 and is used to support the component. The rotation range of the support 4 is ±15°.

[0030] Therefore, by setting up a multi-axis jack and cooperating with the ball joint connected support 4, the overall direction control of the composite jack is achieved by independently adjusting the force of each axis, forming a composite action axis with dynamically adjustable direction, thereby maintaining the stability of the horizontal direction of the force. The four-axis parallel structure realizes the vector synthesis of force, and through dynamic compensation, it realizes the dynamic self-balancing adjustment of the resultant force direction in three-dimensional space, solves the off-center load problem, and breaks through the single-axis direction constraint.

[0031] like Figure 1 , Figure 2As shown, a pressure sensor 23 is installed inside the pump body 21, a displacement sensor 24 is installed on the upper outer wall of the piston rod 22, and an angle sensor 41 is installed on the outer wall of the support 4.

[0032] In practical applications, a central controller (PLC / embedded system) is configured to connect to each axis drive unit via CAN bus / PROFINET. Multi-sensor synchronous sampling (cycle ≤10ms) is triggered by the controller's built-in clock to eliminate timing errors.

[0033] Therefore, by setting pressure sensor 23, displacement sensor 24 and tilt sensor 41, multi-data fusion is achieved to form a multi-dimensional feedback system, which is conducive to realizing four-axis collaborative control, achieving dynamic self-balancing adjustment, and solving the off-center load problem.

[0034] like Figure 2 , Figure 3 As shown, the pump body 21 is provided with a self-locking mechanism 5 for fixing the piston rod 22. The self-locking mechanism 5 includes a locking plate 51, a locking rod 52, a mounting plate 53, and a locking pin 54.

[0035] like Figure 2 , Figure 3 As shown, the locking plate 51 is horizontally disposed on the upper outer wall of the piston rod 22, and the locking rod 52 is vertically disposed on the lower end face of the locking plate 51 and distributed on both sides of the piston rod 22. The mounting plate 53 is horizontally disposed on the outer wall of the pump body 21 and allows the locking rod 52 to slide vertically.

[0036] like Figure 2 , Figure 3 As shown, the locking pin 54 is rotatably connected to the mounting plate 53. The outer wall of the locking pin 54 is provided with multiple layers of locking plates 55 at equal intervals. The outer wall of the locking rod 52 is provided with multiple locking grooves 56 for the locking plates 55 to be inserted after rotation. The locking grooves 56 are provided with a 30° thread shape, and the locking plates 55 fit into the locking grooves 56.

[0037] like Figure 2 , Figure 3 As shown, a guide ball 57 is provided on the locking pin 54, and an arc-shaped guide groove 58 is provided on the mounting plate 53. The guide groove 58 is inclined outward and allows the guide ball 57 to slide.

[0038] like Figure 2 , Figure 3 As shown, a handle 59 is provided at the upper end of the locking pin 54, and an electric cylinder 6 is rotatably connected to the mounting plate 53. The electric cylinder 6 and the handle 59 are rotatably connected by a plug-in shaft 61.

[0039] When any of the hydraulic jacks 2 loses power or malfunctions, the handle 59 can be rotated using the electric cylinder 6. When the electric cylinder 6 malfunctions, the shaft 61 can be pulled out, and the handle 59 can be rotated manually. This causes the handle 59 to rotate the locking pin 54 and the locking plate 55 to be embedded in the locking groove 56. The locking plate 55 and the locking groove 56 are threaded at 30° to reduce the lead angle and enhance self-locking.

[0040] At the same time, when the locking pin 54 rotates, it will drive the guide ball 57 to slide in the guide groove 58. Since the guide groove 58 is inclined, when the locking pin 54 is rotated, the guide ball 57 presses closer and closer to the inner wall of the guide groove 58, achieving double locking, thereby fixing the locking rod 52 and the locking plate 51, and fixing the piston rod 22 in a certain position, ensuring the stability and safety of the entire jack structure during use, and avoiding the risk of overall paralysis of the traditional single-axis system.

[0041] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
