Obviously, the embodiments described 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.

[0026] Reference Figures 1 to 5 , an embodiment provided by the utility model:

[0027] A construction positioning device for a steel sheet pile 1 comprises a plurality of steel sheet piles 1 spliced ​​in sequence, a fixed frame 2 arranged parallel to the front and rear sides of the steel sheet pile 1, and a movable frame 3 slidably connected to the fixed frame 2 left and right: the movable frame 3 is provided with two symmetrically arranged clamping seats 4, and a clamping drive device for driving the two clamping seats 4 to approach and move away from each other, the clamping seats 4 correspond to the positions of the fixed frame 2, and are transmission-connected to the clamping drive device; the clamping seat 4 is provided with a plurality of equidistantly arranged adjustment blocks, a retractable and foldable connecting rod group, and an adjustment drive device for driving the adjustment block to move in the direction of the clamping seat 4, the adjustment block is slidingly connected to the clamping seat 4 and transmission-connected to the adjustment drive device, the connecting rod group is rotatably connected to each adjustment block, and one end is fixedly connected to the clamping seat 4; the adjustment block is provided with a clamping block abutting against the side wall of the steel sheet pile 1, and a clamping drive device for driving the clamping block to move toward the steel sheet pile 1, and the clamping block is transmission-connected to the clamping drive device.

[0028] The steel sheet pile 1 is installed vertically, and its cross-section is a convex structure, including side walls in the middle and flanges on both sides. Adjacent steel sheet piles 1 are spaced apart from each other and overlapped with each other through flanges. During the construction process, the first steel sheet pile 1 is usually driven vertically into the ground as a positioning reference, and the remaining steel sheet piles 1 are spliced ​​in sequence. The two fixed frames 2 are respectively located on the front and rear sides of the steel sheet pile 1 and are arranged in the left and right directions. The mobile frame 3 is slidably connected to the fixed frame 2 and moves in the direction of the fixed frame 2. The two clamping seats 4 are respectively located on the front and rear sides of the mobile frame 3 and are symmetrically arranged. The clamping seats 4 are arranged in the left and right directions and correspond to the positions of the fixed frame 2. The clamping drive device is located in the middle of the mobile frame 3 and is connected to the clamping seat 4. It can be driven by a motor to drive the two clamping seats 4 to move closer to and away from each other.

[0029] Several adjustment blocks are located inside the clamping seat 4, are arranged at equal distances, and are slidably connected to the clamping seat 4, sliding in the left and right directions. The connecting rod group is located above the adjustment block and is a retractable and foldable structure. It is composed of a plurality of connecting rods 6 hinged to each other, one end of which is rotatably connected to each adjustment block, and the other end is fixedly connected to the clamping seat 4. The adjustment drive device is located at one end of the clamping seat 4 and is connected to the adjustment block in a transmission manner. It can be driven by a motor to drive the adjustment block to move in the direction of the clamping seat 4. The clamping block is located on the inner side of the movable frame 3 and is arranged toward the side of the steel sheet pile 1. The clamping drive device is located inside the adjustment block and is connected to the clamping block in a transmission manner. It can be driven by a cylinder to drive the clamping block to move toward the steel sheet pile 1 until it abuts against the side wall of the steel sheet pile 1.

[0030] Since the same type of steel sheet piles 1 are used in the construction of the steel sheet piles 1, the spacing between the steel sheet piles 1 is equal. By setting a connecting rod group, the adjustment blocks set at equal intervals are linked, so that the adjustment blocks can synchronously adjust the spacing between each adjustment block during the movement. When the spacing between the adjustment blocks is equal to the spacing between the steel sheet piles 1, the adjustment blocks and the steel sheet piles 1 correspond one to one, ensuring that each adjustment block can abut against the side wall of the steel sheet pile 1, and the positioning operation is completed in sequence.

[0031] The utility model can synchronize and link multiple adjustment blocks by setting a retractable and foldable connecting rod group, reduce the position adjustment work of the abutment block, make the operation more convenient, and improve the construction efficiency. First, according to the installation position of the steel sheet pile 1, the fixing frame 2 is installed and fixed, the first steel sheet pile 1 is inserted into the inner side of the fixing frame 2, and is vertically driven into the ground as a positioning reference; then, under the drive of the adjustment drive device, the adjustment block moves along the direction of the clamping seat 4, and the connecting rod group drives each adjustment block to be distributed at equal intervals, and consistent with the installation interval of the steel sheet pile 1, ensuring that the adjustment block and the steel sheet pile 1 correspond one to one; then, under the drive of the clamping drive device, the clamping block abuts against the side wall of the first steel sheet pile 1, the next steel sheet pile 1 is driven into the ground, and spliced ​​with the previous steel sheet pile 1; finally, repeat the above process, the clamping block abuts against the side wall of each steel sheet pile 1 in turn, and the clamping positioning of the steel sheet pile 1 is achieved. In addition, under the drive of the clamping drive device, the distance between the two clamping seats 4 can be controlled to pressurize or release the clamping of the steel sheet piles 1, and the movable frame 3 can move along the direction of the fixed frame 2 to facilitate the construction of the next group of steel sheet piles 1.

[0032] In this embodiment, preferably, the connecting rod group includes several groups of staggered folding connecting rods, the ends of adjacent folding connecting rods are hinged to each other, and each group of folding connecting rods includes two connecting rods 6 that are rotatably connected in the middle by a pin 5, and the pin 5 is plugged into the adjustment block.

[0033] Several folding links are staggered in a V-shaped configuration, with the ends of adjacent folding links hinged to each other and connected end to end. Each set of folding links includes two connecting rods 6 and a latch 5. The middle portions of the two connecting rods 6 are hinged to each other, and the latch 5 is installed at the hinged position. The latch 5 is plugged into the adjustment block, and the connecting rods 6 are rotatably connected to the adjustment block via the latch 5. Through the connection between the connecting rod group and each adjustment block, when one adjustment block moves, the folding link drives the adjacent adjustment block to move synchronously. Because one end of the connecting rod group is fixedly connected to the clamping seat 4, the connecting rods 6 rotate relative to each other during the movement of the adjustment block, and the angle between the two connecting rods 6 changes, realizing the telescopic folding function.

[0034] In this embodiment, as a preference, the adjustment block includes an active block 7 that is transmission-connected to the adjustment drive device, and a plurality of driven blocks 8 that are slidingly connected to the clamping seat 4. The active block 7 and the driven block 8 are arranged at equal intervals from left to right.

[0035] The active block 7 and the passive block 8 are arranged from left to right and spaced apart. The distances between the active block 7 and the passive block 8, and between adjacent passive blocks 8, are equal. The active block 7 is in transmission connection with the adjustment drive device, serving as the active component in the adjustment block. The passive block 8 is in sliding connection with the clamping seat 4, serving as the passive component in the adjustment block. The left end of the connecting rod group is rotationally connected to the active block 7, the right end of the connecting rod group is fixedly connected to the clamping seat 4, and the middle part of the connecting rod group is rotationally connected to each passive block 8. Driven by the adjustment drive device, the active block 7 moves to the left along the clamping seat 4, driving the connecting rod group to stretch to the left, driving multiple passive blocks 8 to move synchronously to the left, thereby achieving the effect of synchronous movement and equidistant adjustment.

[0036] In this embodiment, preferably, a travel block 9 fixedly connected to the connecting rod assembly is provided at the right end of the clamping seat 4 , and the travel block 9 is movably mounted on the clamping seat 4 and is tightly connected to the clamping seat 4 .

The travel block 9 is movably mounted on the clamping seat 4, and can be slidably connected to the interior of the clamping seat 4 and fastened to the clamping seat 4 via fasteners. Since the first steel sheet pile 1 serves as the positioning reference, after the spacing between the adjustment blocks is equal to the spacing between the steel sheet piles 1, it is necessary to align the active block 7 with the side wall of the first steel sheet pile 1 to ensure that the position of the driven block 8 corresponds to the remaining steel sheet piles 1. By adjusting the position of the travel block 9 within the clamping seat 4, the starting position of the right end of the connecting rod assembly can be adjusted, thus overcoming the above-mentioned problem.

The active block 7 is sleeved on the outside of the adjusting screw 10 and is transmission-connected to the adjusting screw 10. The middle portion of the driven block 8 is provided with an escape hole for the adjusting screw 10 to pass through. The guide rod 11 is located inside the clamping seat 4, arranged parallel to the adjusting screw 10, and spaced apart.

The mounting plate 13 is located inside the movable frame 3, with one end of the mounting plate 13 facing the steel sheet pile 1 and the other end of the mounting plate 13 being telescopically connected to the clamping drive device. The balancing screw 14 is located inside the mounting plate 13, arranged in the left-right direction, and is rotatably connected to the mounting plate 13. The balancing screw 14 has a bidirectional screw structure, with the threads at both ends of the balancing screw 14 in opposite directions. The two pressure heads 12 are respectively connected to the ends of the balancing screw 14 in a transmission connection. The dial wheel 15 is located in the middle of the balancing screw 14 and is sleeved on the outside of the balancing screw 14. By manually rotating the dial wheel 15, the balancing screw 14 rotates, which drives the pressure heads 12 to move in the opposite direction, bringing the two pressure heads 12 closer or farther away from each other. The width distance between the two pressure heads 12 can be adjusted to accommodate steel sheet piles 1 of different models and sizes, improving the clamping balance.

[0042] In this embodiment, preferably, the clamping drive device includes a clamping cylinder 16 arranged on the adjusting block along the front-to-back direction, and an avoidance groove 17 arranged on the side wall of the clamping seat 4.

[0043] The clamping cylinder 16 is located within the adjustment block, extending in the front-to-back direction, with its telescopic end facing toward the steel sheet pile 1. A clearance groove 17 is located on the sidewall of the clamping base 4, extending along the clamping base 4 and communicating with the interior of the clamping base 4. The clearance groove 17 corresponds to the telescopic end of the clamping cylinder 16, providing clearance for it.
