Description
Technical Field
The utility model belongs to hoist device especially belongs to fluid pressure type guardrail prefabricated section lifting device.
Background
In the production process of new jersey guardrail prefabricated section, generally look for a comparatively level place on the factory and concentrate the preparation, after intensity reaches the design requirement demolish the mould, lift by crane to the finished product and stack the district, carry the prefabricated section by equipment such as crane on the transport vechicle or the practical application, the weight of single piece new jersey guardrail prefabricated section is 4.5t usually, length 4m, because its surfacing, pass the rope by its below usually and hoist, will use the crow bar to assist, cause the prefabricated section lower limb damaged easily. In order to change the rope hoisting mode, the applicant manufactures a hoisting device for the precast block of the new jersey guardrail, applies a patent with the patent number of 2018215108046, and in the using process, as the clamping force is related to the gravity of a hoisted heavy object, when the precast block of the new jersey guardrail is put down, once the new jersey guardrail is unbalanced, a single side is firstly landed, the clamping force of the hoisting device is possibly failed, and the other end is knocked down, so that the precast block of the new jersey guardrail is damaged.
Disclosure of Invention
The utility model aims to overcome the defect that current new jersey guardrail prefabricated section lifts by crane the ware and exists, provide an easy operation, can improve and lift by crane efficiency, prevent to damage the finished product, the fluid pressure type prefabricated section that factor of safety is high lifts by crane the ware.
The utility model discloses the technical scheme who adopts is a fluid pressure type guardrail prefabricated section lifts by crane ware, and its main points lie in: the scissors comprise a hydraulic device, a left scissor arm, a right scissor arm and a rubber pad, wherein a central hinge shaft penetrates through the middle parts of the left scissor arm and the right scissor arm to hinge the left scissor arm and the right scissor arm, the upper ends of the left scissor arm and the right scissor arm are connected with a hydraulic cylinder of the hydraulic device, and the lower end of the scissor arm is wrapped with the rubber pad.
The utility model discloses the use of scissors arm is guaranteeing that the lifting hook is when hanging the heavy object off the ground, and under the effect of gravity, the clamp force is big more. Utilize the clamp force of hydraulic pressure control lifting hook, through manual control hydraulic pressure operating parts, the lifting hook just can relax, like this when putting down the heavy object, even unilateral touchdown, also can not lose the clamp force because of gravity weakens, guarantees the heavy object security.
The upper ends of the left and right scissor arms are connected with a hydraulic cylinder of the hydraulic device, namely the upper ends of the left and right scissor arms are hinged with one end of a connecting arm, and the other end of the connecting arm is connected with the hydraulic cylinder. Because new jersey guardrail prefabricated section thickness is great, and the scissors arm opening degree is big, if the pneumatic cylinder directly meets with the scissors arm, then will use the big pneumatic cylinder of stroke, cause overall structure big, increase a section articulated linking arm, be favorable to reducing the stroke of pneumatic cylinder, reduce whole volume.
The lower end of the scissor arm is an arc which is bent inwards. Ensuring that the scissor arms have an inward clamping force.
The hydraulic device is fixed on the forklift hoisting installation connector. Because the crane is bulky, the prefabrication building site is comparatively crowded, and it is inconvenient to remove, and special fork truck that specially designs and this device matched with lifts by crane installation connector.
The forklift lifting installation connector is composed of a bottom plate, force receiving arms and supporting arms, the bottom plate is a rectangular plane composed of four transverse rods and two vertical rods, the supporting arms and the force receiving arms are fixed on the two transverse rods, which are fixed on the bottom plate and the fork, respectively, the supporting arms are fixedly connected with one end of the bottom plate at right angles, one end of the force receiving arms is fixed with the other end of the bottom plate, the middle part of the force receiving arms is fixed with the other end of the supporting arms to form a triangular support, hanging rods are fixed at the top ends of the two force receiving arms, and a hydraulic device is fixed on the hanging rods.
The bottom plate is directly fixed on a fork of the forklift, and the flexibility of the forklift is utilized to meet the requirement of hoisting.
The utility model is simple in operation, it is quick, lift by crane efficiently. The scissor arm is used for ensuring that the clamping force is larger under the action of gravity when the lifting hook lifts a heavy object off the ground. Utilize the clamp force of hydraulic pressure control lifting hook, through manual control hydraulic pressure operating parts, the lifting hook just can relax, like this when putting down the heavy object, even unilateral touchdown, also can not lose the clamp force because of gravity weakens, has avoided the damaged defect of new jersey guardrail. The utility model discloses also can be used to hoist other heavy objects, like the reinforcing bar etc.
