Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in attached figures 1 and 2, the attached figure 1 is a schematic view of the overall structure of the cement clamp in a horizontal hanging state, and two groups of clamps are symmetrically arranged below a cross beam to transversely hoist a cement plate; figure 2 is the utility model discloses an erect overall structure sketch map under the state of hanging, at least only need use a clamp centre gripping can accomplish on cement panel and lift by crane. The clamp comprises a fixed clamp seat 2, a movable tongue plate 7 and a hanging ring 5, wherein the fixed clamp seat 2 is of a U-shaped plate structure, the fixed clamp seat 2 comprises a first clamp arm 3, a second clamp arm 4 and a connecting arm 9 for connecting the first clamp arm 3 and the second clamp arm 4, the middle section of the movable tongue plate 7 is hinged to the free end of the first clamp arm 3 through a hinge shaft 6, the rotation axis direction of the movable tongue plate 7 is perpendicular to the U-shaped section direction of the fixed clamp seat, one end of the movable tongue plate 7 faces the second clamp arm 4 and forms a clamping end, a contact point 10 of the movable tongue plate 7 and a plate 8 is positioned in a U-shaped area between the connecting arm 9 and the hinge shaft 6, the other end of the movable tongue plate 7 is far away from the first clamp arm 3 and is connected with a sling 2, the hanging ring 5 is rotatably arranged at one end of the first clamp arm 3 far away from the hinge shaft 6, the rotation axis of the hanging ring 5 is in the same direction as the rotation axis of, the sling 1 penetrates through the inner ring of the hanging ring 5, the sling 1 penetrates through the hanging ring and then is connected with the movable tongue plate 7, the movable tongue plate 7 is driven to rotate, the sling 1 conducts guiding and limiting through the hanging ring 5, the sling 1 always conducts the pulling force direction of the movable tongue plate 7 along the direction of the first clamping arm 3, and therefore the clamp can be suitable for two states of horizontal hanging and vertical hanging, the replacement of the clamp can be reduced in construction, and the construction efficiency is improved.

The first clamping arm 3 is provided with a U-shaped mounting groove 11 from the free end to the beginning along the length direction, and the movable tongue plate 7 is hinged in the mounting groove 11. The movable tongue plate 7 is of a crescent or V-shaped bent structure and the like, the concave side of the movable tongue plate 7 is arranged towards the connecting arm 9 and is also arranged towards the connecting arm 9, so that the clamping end of the movable tongue plate 7 is inclined to the second clamping arm 4, and the movable tongue plate rotates towards one side far away from the connecting arm 9 and clamps the plate 8 in a sling lifting state.

The surfaces of the two clamping arms 4, which are in contact with the plate 8, and the surfaces of the movable tongue plates 7, which are in contact with the plate 8, are in a zigzag structure, so that the clamping force between the clamping surfaces of the clamps and the plate is increased, and the clamping stability is ensured.

In the actual hoisting process, the sling swings in the air with a certain amplitude and vibrates and shakes to a certain extent, so that the phenomenon that a clamping point between the clamp and a plate has play and relatively slightly slides can be caused, particularly, the plate is easy to break away and fall under the vertical hoisting state, therefore, the structure shown in the attached drawings 3 and 4 is adopted, the anti-skid component is further included, a guide groove 12 is concavely arranged in one side surface of the second clamping arm 4 opposite to the first clamping arm 3, the anti-skid component is arranged in the guide groove 12, and the anti-skid component contacts the plate 8 under the clamped state;

anti-skidding subassembly includes slider 14, guide bar 13 and spring release 15, slider 14 is in the panel contact, guide bar 13 sets up along the length direction of second arm lock 4, just guide bar 13 is close to the one end of linking arm 9 and is greater than the distance that the linking arm 9 was kept away from to guide bar 13 apart from the one end of second arm lock clamping surface 16 apart from the distance of second arm

lock clamping surface

16, 14 covers of slider are established and are slided on guide bar 13, spring release 15 covers is established on guide bar 13, just spring release's both ends are connected respectively on slider 14 and keep away from on the terminal surface of linking arm 9 in guide groove 12. When the spring return piece 15 is in a free state (i.e. in a state of not clamping the plate 8), the slider 14 abuts against one end surface close to the connecting arm in the guide groove 12, the end surface is a limiting surface 17, and at this time, one side surface of the slider 14 facing the plate 8 is not lower than the clamping surface 16 of the second clamping arm; under the state of clamping plate 8, the slider is in close contact with the plate, when the sling vibrates in the air, the movable tongue plate 7 is loosened instantly, the gap between the clamping end of the movable tongue plate 7 and the clamping surface 16 of the second clamping arm is increased, the plate slightly slides in the instant time, and at the moment, the slider is in close contact with the plate, the plate moves downwards and simultaneously drives the slider 14 to move along the guide rod 13, so that the gap generated by loosening of the movable tongue plate 7 is compensated, the stable clamping of the movable tongue plate 7 and the second clamping arm is ensured, and the lifting stability is greatly improved.

A plurality of convex cones 20 in a taper shape are convexly arranged on one surface of the sliding block 4 facing the plate 8; in the clamped state, the male cone 2 is embedded in the sheet material 8, further ensuring the close contact of the slide 14 with the sheet material.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
