[0002] Twist-type workpieces are mostly used in coastal engineering, which can effectively buffer the impact of waves and provide certain protection for buildings on the shore. In addition to coastal engineering, twist-type workpieces are also suitable for construction projects such as docks and bridges, as well as industrial sites and municipal construction, providing high-quality building materials for these sites. Twist-type workpieces are usually large in size and weight. At present, during construction, it is usually necessary to manually tie the twist-type workpiece with a sling, and then use a crane to lift the twisted workpiece.

In addition, the personnel are close to the twist-type workpiece, which poses certain safety hazards. Therefore, a twist-type workpiece grabbing device that is easy to carry and highly safe is needed. Utility Model Content

[0015] In order to make the present invention clearer and more understandable, the technical solution of the present invention is further described in detail below in combination with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one of the implementation methods and does not represent all embodiments.

[0016] In this article, terms such as "up, down, vertical, horizontal, front, and back" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection.

[0017] Combined with Figure 1 and attached Figure 2 A torsion body grasping device includes a connecting seat 4, a rotary solenoid valve 6 is fixed at the bottom end of the connecting seat 4, the output end of the rotary solenoid valve 6 is connected to a mounting seat 1, a first clamping jaw 3 is fixed at one end of the mounting seat 1, and a second clamping jaw 2 is hinged at the other end of the mounting seat 1, and an electromagnetic push rod 5 is installed on the mounting seat 1, and the output end of the electromagnetic push rod 5 moves in a direction away from the first clamping jaw 3, and the output end of the electromagnetic push rod 5 is hinged to the second clamping jaw 2, and the hinge point between the electromagnetic push rod 5 and the second clamping jaw 2 is located above the hinge point between the mounting seat 1 and the second clamping jaw 2. The side of the connecting seat 4 away from the rotary solenoid valve 6 is connected to a lifting equipment such as a crane or an excavator, and a bolt hole can be set on the side of the connecting seat 4 away from the rotary solenoid valve 6, and the connection with the lifting equipment is fixed by bolts. The way of connecting the lifting equipment with equipment such as buckets and grippers is conventional technology, and the specific connection form between the connecting seat 4 and the lifting equipment can be designed according to the type of lifting equipment, which will not be elaborated here. The rotary solenoid valve 6 is used to rotate the first clamping jaw 3 and the second clamping jaw 2. When the output end of the electromagnetic push rod 5 is extended, the second clamping jaw 2 is closed, and when the output end of the electromagnetic push rod 5 is retracted, the second clamping jaw 2 is opened.

[0018] Specifically, the mounting base 1 is in an inverted U shape, that is, the mounting base 1 includes a top plate and two side plates respectively fixed on the front and rear sides of the top plate, the first clamping jaw 3, the second clamping jaw 2, and the electromagnetic push rod 5 are all located between the two side plates, and the end of the electromagnetic push rod 5 away from its output end is hinged to the mounting base 1.

[0019] Specifically, the upper part of the first clamping jaw 3 close to the second clamping jaw 2 is a first arc surface, and the lower part of the first clamping jaw 3 close to the second clamping jaw 2 is a first vertical surface. The first arc surface is in the shape of a quarter arc, and the top end of the first arc surface is tangent to the horizontal direction, and the bottom end of the first arc surface is tangent to the first vertical surface.

[0020] When the second clamp 2 is fully opened, the upper part of the second clamp 2 near the first clamp 3 is a second arc surface, and the lower part of the second clamp 2 near the first clamp 3 is a second vertical surface. The second arc surface is in the shape of a quarter circle, the top of the second arc surface is tangent to the horizontal direction, the bottom of the second arc surface is tangent to the second vertical surface, and the second vertical surface is parallel to the first vertical surface. The design of the vertical surface makes it easier to place the two clamps on both sides of the torsion body 7. As the second clamp 2 is closed, the second clamp 2 pushes the torsion body 7 toward the direction close to the first clamp 3 and lifts the torsion body 7. Since the first clamp 3 is fixed, the torsion body 7 cannot continue to move horizontally after approaching the first clamp 3. The second clamp 2 lifts the torsion body 7 to the position of the arc surface. After the second clamp 2 is closed, the two arc surfaces form a shuttle-shaped clamping space, that is, the clamping space is narrow at both ends and wide in the middle. The torsion body 7 is located in the middle part of the clamping space and cannot move toward both ends, so the clamping effect is better.

[0021] Specifically, the center distance X2 from the hinge point of the electromagnetic push rod 5 and the second clamping jaw 2 to the hinge point of the mounting base 1 and the second clamping jaw 2 is 104mm, the radius R2 of the first arcuate surface is 130mm, the radius R1 of the first arcuate surface is 184mm, the length H2 of the first vertical surface is 150.5mm, the length H1 of the second vertical surface is 141.5mm, and when the second clamping jaw 2 is fully opened, the horizontal spacing between the first vertical surface and the second vertical surface is 1140mm.

[0022] Specifically, a flexible gasket is provided on one side of the first clamping jaw 3 close to the second clamping jaw 2, and a flexible gasket is provided on one side of the second clamping jaw 2 close to the first clamping jaw 3. The flexible gasket can be made of rubber. The flexible gasket can protect the twisting body 7 and avoid damaging the twisting body 7 during the grasping process.

[0023] Specifically, the connecting seat 4, the mounting seat 1, the first clamping jaw 3 and the second clamping jaw 2 are all made of Q235 steel, which has good rust resistance, high strength and long service life.

[0024] Specifically, it also includes an electric control handle, which includes a forward button, a reverse button, a clamp closing button, a clamp opening button, and a control unit, and the control unit is respectively connected to the forward button, the reverse button, the clamp closing button, the clamp opening button, the rotary solenoid valve 6, and the electromagnetic push rod 5; when the forward button or the reverse button is pressed, the control unit receives a rotation control instruction, and transmits a control signal to the rotary solenoid valve 6 to control the output end of the rotary solenoid valve 6 to rotate forward or reverse; when the clamp closing button or the clamp opening button is pressed, the control unit receives a grasping / releasing control instruction, and transmits a control signal to the electromagnetic push rod 5 to control the output end of the rotary electromagnetic push rod 5 to retract or extend. Remotely controlling the actions of the electromagnetic valve and the electromagnetic push rod 5 by buttons is a conventional technology and will not be described in detail here.

[0025] Usage process: connect the connecting seat 4 to a lifting equipment such as a crane or an excavator, and the lifting equipment moves the grasping device to the position of the torsion body 7 to be transported. When grasping the torsion body 7, the electromagnetic push rod 5 contracts, and the second clamp 2 opens. Use the lifting equipment to move the grasping device so that the torsion body 7 is located between the first clamp 3 and the second clamp 2. Then the electromagnetic push rod 5 extends, and the second clamp 2 closes. The second clamp 2 and the first clamp 3 clamp the torsion body 7, and then the lifting equipment is used to transport the torsion body 7 to the target position.
