The utility model is suitable for a stone material of different specifications, convenient to use can shorten stone material hoist and mount time greatly.

Description

Stone clamp

Technical Field

The utility model belongs to the technical field of the construction machinery, especially, relate to a stone material anchor clamps.

Background

In the construction process of buildings, roads, bridges, gardens and the like, stone materials are often needed. These stones have been generally processed into regular geometric bodies, and have difficulties in volume, weight and difficulty in handling. Most stones in the prior art need to be hoisted by adopting an auxiliary hoisting tool, and the auxiliary hoisting tool is difficult to fix and needs a long time.

The applicant finds in practice that the stone has a plurality of regular surfaces, at least two opposite planes can be found, and therefore the hoisting included angle can be designed by utilizing the characteristic. Based on this, provide the technical scheme of the utility model.

Disclosure of Invention

The utility model aims at providing a stone material anchor clamps can hoist and mount stone material convenient and fast ground.

Therefore, the utility model adopts the technical proposal that: a stone material anchor clamps which characterized in that: the clamping device comprises two L-shaped clamping edges, wherein the long edges of the two L-shaped clamping edges are pivoted through a pivot, and the tail ends of the short edges of the two L-shaped clamping edges are provided with inward clamping surfaces; the long-edge tail ends of the two L-shaped clamping edges are connected through a hard and flexible connecting piece.

The hard flexible connecting piece has no elasticity and is not extensible; flexible means that it has a variable shape of appearance. The preferred embodiment is an iron chain.

Furthermore, a plurality of through holes are formed in the long edge of at least one L-shaped clamping edge, and the pivot shaft penetrates through the through holes.

The clamping surface is provided with an elastic friction pad.

When the utility model is used, firstly, the stone surface to be clamped is determined, and the pivot is penetrated through by selecting a proper through hole according to the specification and the size of the stone, thereby adjusting the end distance of the short edges of the two L-shaped clamping edges and ensuring that the opening size of the clamp is more than or equal to the size of the part to be clamped of the stone; and then buckling the iron chain into a lifting hook of a crane, carrying out trial lifting, and carrying out subsequent lifting operation after the stone is firmly fixed.

The utility model clamps the stone material by two clamping surfaces through the scissor-shaped opening and closing of the two clamping edges; the elastic friction pad increases the friction force between the clamping surface and the stone surface, so that the clamping is more stable; after the hoisting is in place, the clamp can be loosened by hoisting, and the use is convenient; a plurality of through-holes on the clamping edge then make the utility model discloses the opening size is adjustable, is applicable to the stone material of different specifications.

It is visible, the utility model discloses convenient to use can shorten stone material hoist and mount time greatly.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

See the drawings. The stone clamp of the embodiment comprises two L- shaped clamping edges 1, 2, only one of which will be described hereinafter, since the two clamping edges are identical. The clamping edge 1 consists of a long edge 11 and a short edge 12 to form an L shape; five through holes 14 are formed in the middle of the long side 11, the tail end of the short side 12 is provided with an inward clamping surface 13, and the clamping surface 13 is provided with a rubber friction pad 5; the pivot 4 passes through one of the through holes of the long sides to pivot the clamping edges 1 and 2 together, and the clamping edges 1 and 2 can rotate around the pivot 4. It should be noted that the clamping edges 1 and 2 are provided with five through holes, so that various arrangements can be provided for the pivot to pass through.

The iron chains 3 are connected to the ends of the two long sides 11, respectively. When the stone clamping device works, the middle part of the iron chain is hung on the lifting hook, the iron chain is stressed to be collapsed, the clamping edges 1 and 2 are driven to rotate around the pivot 4, and the two friction pads 5 are enabled to oppositely clamp or release the stone.
