At this time, the horizontal connecting plate in the middle of the H- or Z-shaped steel sheet pile is on the inner side of the two clamping block guide housings 4117, and the two sides are on the outer sides of the left and right sets of clamping block guide housings 4117. At this time, the two electric push rods 4124 provided on the two control frame bodies 411 pull the two expansion rods 4125 to move toward the side close to each other. During the movement of the two expansion rods 4125, the two push-pull rods 4128 are driven to slide in the push-pull rod guide grooves 4122 provided on the two push-pull rod guide plates 4121. The two push-pull rods 4 128 drives the two triangular push blocks 4129 to move toward each other, and the outer walls of the two triangular push blocks 4129 respectively push the oblique sections opened on the inner sides of the front and rear sets of moving plates 4143. Since the inclinations of the oblique sections opened on the inner sides of the front and rear sets of moving plates 4143 are opposite, the two triangular push blocks 4129 will respectively push the front and rear sets of moving plates 4143 to move away from each other during the movement process, and the front and rear sets of moving plates 4143 respectively drive the front and rear sets of moving plate connecting rods 4142 to move, and the front and rear sets of moving plate connecting rods 4142 respectively drive the middle parts of the left and right sets of arc-shaped rotating rods 4141 to rotate with the hinge block 4114 as the center of the circle, and the left and right sets of arc-shaped rotating rods 414 1 respectively pushes the front and rear groups of clamp block connecting blocks 4144 to move toward each other, and the front and rear groups of clamp block connecting blocks 4144 respectively drive the two clamp blocks 4145 to move inward on the inner sides of the two clamp block guide housings 4117 until the two clamp blocks 4145 tightly clamp the horizontal connecting plate in the middle of the H or Z-shaped steel sheet pile. At the same time, the two electric push rods 4124 pull the two expansion rods 4125 to move toward each other, and the two expansion rods 4125 drive the two side clamp plate connecting rods 4126 and the two L-shaped welding point clamp rods 423 to engage in the L-shaped welding point clamp rod sliding grooves 422 provided on the inner walls of the two electric push rod base plates 4123 and the two L-shaped welding point clamp rod guide plates 421. Sliding toward the side closer to each other, the two side clamping plate connecting rods 4126 drive the two side clamping plates 4127 to move toward the side closer to each other until the two side clamping plates 4127 and the two L-shaped welding point clamping rods 423 tightly clamp the two sides of the H or Z-shaped steel sheet pile, thereby completing the wrapping clamping work of the non-U-shaped steel sheet pile. At this time, the L-shaped welding point clamping rods 423 and the side clamping plates 4127 on both sides of the steel sheet pile present an inverted T-shaped clamping state, the L-shaped welding point clamping rods 423 fix the welding points between the horizontal connecting plate and the side plates on both sides, and the side clamping plates 4127 fix the non-welding points between the horizontal connecting plate and the side plates on both sides, ensuring that the steel sheet pile will not be displaced or deformed during the clamping process, thereby improving the stability and reliability of the clamping.

[0021] The working principle of the present invention is as follows: when it is necessary to clamp non-U-shaped steel sheet piles, such as H-shaped or Z-shaped steel sheet piles, the pile controller 2 controls the pile gripper housing 3 and the limit mechanism 4 to be sleeved on the outer wall of the steel sheet pile. At this time, the horizontal connecting plate in the middle of the H- or Z-shaped steel sheet pile is on the inner side of the two clamping block guide housings 4117, and the two sides are on the outer sides of the left and right sets of clamping block guide housings 4117. At this time, the two electric push rods 4124 provided on the two control frame bodies 411 pull the two expansion and retraction rods 4125 to move toward each other. In the process of movement, the two expansion and retraction rods 4125 drive the two push rods 4124 to move closer to each other. The pull rod 4128 slides in the push-pull rod guide groove 4122 opened in the two push-pull rod guide plates 4121, and the two push-pull rods 4128 drive the two triangular push blocks 4129 to move toward each other. The outer walls of the two triangular push blocks 4129 respectively push the oblique cut surfaces opened on the inner sides of the front and rear sets of moving plates 4143. Since the inclinations of the oblique cut surfaces opened on the inner sides of the front and rear sets of moving plates 4143 are opposite, the two triangular push blocks 4129 will respectively push the front and rear sets of moving plates 4143 to move away from each other during the movement process. The front and rear sets of moving plates 4143 respectively drive the front The rear two groups of moving plate connecting rods 4142 move, and the front and rear groups of moving plate connecting rods 4142 respectively drive the middle parts of the left and right groups of arc-shaped rotating rods 4141 to rotate with the hinge block 4114 as the center of the circle. The outer sides of the left and right groups of arc-shaped rotating rods 4141 respectively push the front and rear groups of clamping block connecting blocks 4144 to move toward each other. The front and rear groups of clamping block connecting blocks 4144 respectively drive the two clamping blocks 4145 to move inward on the inner sides of the two clamping block guide shells 4117 until the two clamping blocks 4145 tightly clamp the horizontal connecting plate in the middle of the H or Z-shaped steel sheet pile. At the same time, the two electric push rods 412 While pulling the two expansion and retraction vertical rods 4125 toward each other, the two expansion and retraction vertical rods 4125 drive the two side clamping plate connecting rods 4126 and the two L-shaped welding point clamping rods 423 to slide toward each other along the L-shaped welding point clamping rod sliding grooves 422 provided on the inner walls of the two electric push rod base plates 4123 and the two L-shaped welding point clamping rod guide plates 421. The two side clamping plate connecting rods 4126 drive the two side clamping plates 4127 toward each other until the two side clamping plates 4127 and the two L-shaped welding point clamping rods 423 tightly clamp the two sides of the H- or Z-shaped steel sheet pile.
