Description

Technical Field

[0001] The invention relates to the technical field of steel sheet pile placing equipment, and in particular to a steel sheet pile driving machine. Background Art

[0002] Steel sheet piles are a commonly used temporary or permanent support structure used in civil engineering, water conservancy engineering, construction and other fields. Steel sheet pile driving refers to the process of driving steel sheet piles into the foundation to form a continuous wall for retaining, waterproofing or supporting structures. Related technologies usually require manual support of steel sheet piles in pile driving operations to locate the position of the steel sheet piles. This method has certain safety hazards and will also affect the efficiency of steel sheet pile driving.

[0003] The patent document with the authorization announcement number CN118390518B discloses a steel sheet pile driving device, including a steel sheet pile body, a plurality of the steel sheet pile bodies are buckled with each other, and the side walls of the steel sheet pile body are tightly attached to guide rods, the side walls of the guide rods are provided with supporting mechanisms, and the two ends of the guide rods are provided with fixing mechanisms, and the fixing mechanisms are installed on the fixing mechanisms. A limiting mechanism is movably provided on the moving mechanism; the two ends of the two guide rods are covered with the fixing mechanisms, and the steel sheet pile body is inserted into the clamping space between the two guide rods, and the guide rods are fixed and merged by the fixing mechanisms so that the two guide rods clamp the steel sheet pile body to guide the driving of the steel sheet pile body, and the moving mechanism is used to adjust the position of the limiting mechanism to adapt to the width of the steel sheet pile body, and the limiting mechanism limits the position of the steel sheet pile body at the two ends to avoid positional displacement of the steel sheet pile body at the two ends.

[0004] Steel sheet piles generally have a large weight and height. During construction operations, lifting equipment is required to lift the steel sheet piles and move them to the predetermined piling position. The lifting equipment is fixed to the upper end of the steel sheet piles. During the lifting and moving process of the steel sheet piles, the lower end of the steel sheet piles will swing to a certain extent due to the weight and height of the steel sheet piles. The steel sheet pile driving machine provided by the above patent document can position the steel sheet piles during the steel sheet pile driving process, but in the operation of lifting and unloading the steel sheet piles, it is still necessary to manually support the bottom of the steel sheet piles to locate the unloading position of the steel sheet piles. In addition, the steel sheet piles are mainly used for retaining soil during the piling operation. In order to prevent the soil from sliding or collapsing, the steel sheet piles need to be inserted to a sufficient depth to resist the pressure of the soil. As the insertion depth of the steel sheet piles increases, the resistance to the insertion of the steel sheet piles will increase, and there are certain differences in geological conditions in different construction environments. When encountering hard soil layers or stone blocks during the steel sheet pile driving process, the steel sheet pile driving machine provided by the above patent document cannot adjust the driving strength of the steel sheet piles. Summary of the invention

[0005] The present invention provides a steel sheet pile driving machine, aiming to solve the problem that the steel sheet pile driving machine in the related art cannot position the steel sheet pile when it is lowered to a preset piling position, and it is inconvenient to flexibly adjust the driving strength according to the change of soil properties during the steel sheet pile driving process.

[0015] Preferably, a positioning portion is provided at one end of the two movable members away from the positioning member, and the positioning portion is plate-shaped and is used to fit with the side wall of the steel sheet pile.

[0023] (1) It is convenient to position the steel sheet pile in the process of lowering the steel sheet pile to the preset piling position, and the driving strength can be flexibly adjusted according to the change of soil properties during the steel sheet pile driving process. The steel sheet pile moves down from between the two positioning parts, and the adjustment component drives the two connecting parts to move relative to each other, and drives the two positioning parts to approach relatively. In the process of the positioning parts approaching the steel sheet pile, the two movable parts move away and abut against the two side walls of the steel sheet pile to achieve the positioning of the steel sheet pile. If the steel sheet pile encounters a hard soil layer or a stone obstruction, the pressure of the connecting parts and the positioning parts increases, and the positioning parts and the connecting parts are in a state of relative squeezing and approaching. When the insertion of the steel sheet pile is blocked, the striking component starts to work, and the striking parts strike the positioning parts at intervals to increase the force when the steel sheet pile is inserted into the soil layer, so that the steel sheet pile can break through the resistance during insertion and be smoothly inserted into the soil layer.

The positioning part pulls the steel sheet pile out of the soil layer for a short distance. This operation can temporarily release the constraint on the steel sheet pile in the soil layer, giving the steel sheet pile some space for adjustment. At the same time, this operation can temporarily reduce the pressing force on the steel sheet pile, thereby reducing the resistance of the soil to the steel sheet pile, and also facilitate the insertion operation of the steel sheet pile when it encounters resistance.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1 and Figure 2 As shown, the steel sheet pile driving machine of the present invention comprises a frame 2 and a moving mechanism 1, wherein the moving mechanism 1 drives the frame 2 to move at the construction site according to the preset piling position of the steel sheet pile 5, wherein the moving mechanism 1 includes but is not limited to a crawler-type walking mechanism, a tire-type walking mechanism or an auxiliary walking device, and the moving mechanism 1 is responsible for moving the frame 2 at the construction site to ensure that different working positions can be flexibly reached, and the structural design of the moving mechanism 1 can be based on the conditions of the construction site (such as ground type, terrain, etc.) to ensure the stability and maneuverability of the frame 2, and in actual operation, the construction personnel select a suitable moving mechanism 1 according to the construction conditions, and the structure and selection method of the moving mechanism 1 belong to the prior art and will not be described in detail here.

[0033] like Figure 2 and Figure 3As shown, the frame 2 is provided with two groups of positioning members 4 and two groups of striking components, and the two groups of striking components are respectively on the upper sides of the two groups of positioning members 4. The striking components include a connecting member 3, a striking member 31 and a driving structure. The connecting member 3 cooperates with the frame 2 in lifting and lowering. Specifically, a lifting part 21 is provided on the frame 2, and the lifting part 21 cooperates with the frame 2 in longitudinal sliding. The lifting part 21 can be directly connected to the frame 2 through a lifting cylinder 22, and the lifting cylinder 22 drives the lifting part 21 to rise and fall relative to the frame 2. The connecting member 3 is slidably connected to the lifting part 21 in the horizontal direction through an adjusting component, and the adjusting component drives the two connecting members 3 to be relatively close to or away from each other. The adjusting component includes two adjusting cylinders, and the protruding ends of the two adjusting cylinders are respectively connected to the two connecting members 3. The two adjusting cylinders drive the two connecting members 3 to be relatively far away from or close to each other. The connecting member 3 is elastically connected to the positioning member 4, and the two connecting members 3 drive the two positioning members 4 to be relatively far away from or close to each other. The striking member 31 cooperates with the connecting member 3 in longitudinal sliding through the elastic member, and the driving structure pushes the striking member 31 upward at intervals and causes the elastic member to accumulate force.

[0034] The driving structure includes a driving member, a driving shaft 32 and a push plate 33. The driving member is installed on the connecting member 3. The driving member can be a motor. The driving member can be directly connected to the driving shaft 32, or can be connected to the driving shaft 32 through a transmission belt or a transmission chain. The driving member drives the driving shaft 32 to rotate. The push plate 33 is fixed on the driving shaft 32. A pressing part is fixed on the striking member 31. When the driving shaft 32 rotates, the push plate 33 contacts the pressing part at intervals and pushes the pressing part to drive the striking member 31 to move upward. When the striking member 31 moves upward relative to the connecting member 3, the elastic member is squeezed to store force in the elastic member. The elastic member can be a spring. After the push plate 33 is separated from the pressing part, the striking member 31 hits the positioning member 4 under the elastic force of the elastic member.

[0035] like Figure 4 As shown, a positioning assembly is also provided on the positioning member 4, and the positioning assembly includes two movable members 43, and the two movable members 43 slide and cooperate with the positioning assembly in the horizontal direction. The two movable members 43 are respectively used to movably abut against the two side edges of the steel sheet pile 5, and a positioning portion 44 is provided at one end of the two movable members 43 away from the positioning member 4. The positioning portion 44 is plate-shaped, and the positioning portion 44 is used to fit with the side wall of the steel sheet pile 5. A connecting cavity 41 is provided in the positioning member 4, and the two movable members 43 slide and cooperate with the connecting cavity 41 respectively. The connecting cavity 41 is also connected with a trigger member 42, with the side facing the steel sheet pile 5 as the front side, and the trigger member 42 is provided on the front side of the positioning member 4. When the trigger member 42 and the two movable members 43 slide relative to the connecting cavity 41, the space in the connecting cavity 41 is changed, and the connecting cavity 41 is isolated from the external space. A receiving groove 45 is provided at the front end of the positioning member 4. When the front end of the positioning member 4 fits with the steel sheet pile 5, the trigger member 42 is squeezed into the receiving groove 45.

[0036] When the steel sheet pile 5 is driven, the steel sheet pile 5 to be inserted is first hoisted to the preset driving position by the hoisting equipment, and the hoisting equipment gradually lowers the steel sheet pile 5, and the steel sheet pile 5 moves down from between the two positioning members 4. The adjustment component drives the two connecting members 3 to move relative to each other, and drives the two positioning members 4 to move relatively close to each other, until the trigger member 42 on the positioning member 4 contacts the steel sheet pile 5. As the positioning member 4 gradually approaches the steel sheet pile 5, the trigger member 42 is squeezed to slide relative to the connecting cavity 41, and squeezes the space in the connecting cavity 41, and the interior of the connecting cavity 41 presents a relatively In the closed cavity, when the internal space of the connecting cavity 41 is squeezed, the two movable parts 43 move relatively away from each other under the influence of the pressure change in the connecting cavity 41, until the positioning part 44 at the end of the movable part 43 fits with the side wall of the steel sheet pile 5. The positioning component is used to automatically position the lower end of the steel sheet pile 5 when the steel sheet pile 5 is lowered, thereby reducing the intervention of manual operation and improving the accuracy of the lowering position of the steel sheet pile 5. After the two positioning parts 4 are fully fitted with the two end surfaces of the steel sheet pile 5, the lifting cylinder 22 drives the lifting part 21 to move downward as a whole, further pushing the steel sheet pile 5 into the soil layer.

[0037] The connecting member 3 is elastically connected to the positioning member 4, and the connecting member 3 and the positioning member 4 can be connected by a spring or an elastic telescopic rod. Since there are certain differences in the properties of the soil layers in different construction environments, during the process of inserting the steel sheet pile 5 into the soil layer, if the steel sheet pile 5 encounters a hard soil layer or a stone obstruction, the pressure of the connecting member 3 and the positioning member 4 increases, and the spring or elastic telescopic rod connecting the positioning member 4 is fully squeezed. A position sensor or a pressure sensor can be set on the positioning machine to timely obtain the obstruction of the insertion of the steel sheet pile 5. When the insertion of the steel sheet pile 5 is obstructed, the striking assembly starts working, and the striking member 31 strikes the positioning member 4 at intervals to increase the force of the steel sheet pile 5 when it is inserted into the soil layer, so as to facilitate the steel sheet pile 5 to break through the resistance during the insertion operation and smoothly insert into the soil layer.

[0038] like Figure 2 and Figure 3As shown, when the steel sheet pile 5 is blocked when inserted into the soil layer, it is easy to tilt. The steel sheet inserted into the soil layer tilted cannot effectively resist the soil pressure, which affects the supporting effect of the steel sheet pile 5 on the soil layer. Extra time and resources are needed for adjustment in the later stage, and the construction difficulty and complexity are increased. In order to ensure the insertion accuracy of the steel sheet pile 5 and reduce the deviation of the position of the steel sheet pile 5, a moving part 23 is also provided on the frame 2. The moving part 23 cooperates with the frame 2 in lifting and lowering. The moving part 23 can be pushed up by the cylinder, and can also be driven longitudinally by the screw. The moving part 23 is located at the lower side of the positioning part 4, and the positioning part 4 is movably abutted against the moving part 23. When the insertion of the steel sheet pile 5 is blocked, the moving part 23 can be driven to move upward to push the positioning part 4 upward. The positioning part 4 pulls the steel sheet pile 5 out of the soil layer for a short distance, temporarily reducing the pressing force on the steel sheet pile 5, thereby reducing the soil's resistance to the steel sheet pile 5. This operation can temporarily release the constraints on the steel sheet pile 5 in the soil layer, giving the steel sheet pile 5 an adjustment space, so that the steel sheet pile 5 can be corrected in time when the steel sheet pile 5 is offset. In addition, by temporarily pulling the steel sheet pile 5 out of the soil for a certain distance, the contact between the soil layer and the steel sheet pile 5 can be improved when the steel sheet pile 5 is reinserted into the soil layer, thereby facilitating the smooth insertion of the steel sheet pile 5 into the soil layer.

[0039] The frame 2 is also provided with two guide members 24, which are respectively movably abutted against two side surfaces of the steel sheet pile 5. The end surfaces of the guide members 24 that are used to contact the steel sheet pile 5 are provided with rollers. The guide members 24 are in rolling contact with the steel sheet pile 5 and are used to guide the position of the steel sheet pile 5 when the steel sheet pile 5 is inserted. In order to further detect the displacement of the steel sheet pile 5 during the insertion process and to facilitate timely correction of the steel sheet pile 5, pressure sensors are provided on the two guide members 24. The difference in pressure generated by the steel sheet pile 5 on the guide members 24 on both sides can be detected by the two pressure sensors. The pressure difference monitored by the two pressure sensors can be used to determine the inclination of the steel sheet pile 5. When the two pressure sensors detect an obvious force difference, it can be determined that the steel sheet pile 5 has tilted, and the moving member 23 can be started to correct the steel sheet pile 5.

[0040] The adjacent steel sheet piles 5 are interlocked by locks. During the insertion process of the steel sheet piles 5, the impact force of the inserted steel sheet piles 5 may affect the adjacent steel sheet piles 5 that have been inserted, causing the inserted steel sheet piles 5 to continue to move downward. In order to reduce the impact on the adjacent steel sheet piles 5, a limit assembly is also provided on the frame 2. The limit assembly includes two telescopic cylinders and two limit members 25. The protruding ends of the telescopic cylinders are respectively connected to the two limit members 25. The opposite ends of the two limit members 25 are provided with limit parts. The limit parts and the limit members 25 are telescopically matched. The limit parts are used to movably abut against the adjacent steel sheet piles 5 adjacent to the steel sheet piles 5 in the insertion operation. The limit parts can be connected to the limit members 25 through the cylinder. When the steel sheet piles 5 are inserted and driven, they are first abutted against the adjacent steel sheet piles 5 through the two limit parts to limit the positions of the adjacent steel sheet piles 5 and reduce the impact of the insertion and driving operation on them.

[0041] The steel sheet pile driving machine provided by the present invention is convenient for positioning the steel sheet piles during the lowering process of the steel sheet piles, and at the same time, the driving method of the steel sheet piles can be flexibly adjusted according to the properties of the soil layer during the driving process, so as to facilitate the smooth insertion of the steel sheet piles into the soil layer and improve the insertion accuracy of the steel sheet piles, thereby reducing the dependence on manual operation and effectively improving the quality of the steel sheet pile driving construction.
