Abstract
The utility model relates to the technical field of a forklift slant oil cylinder mechanism, in particular to a shock absorption block for the forklift slant oil cylinder mechanism. The shock absorption block for the forklift slant oil cylinder mechanism comprises a body. A through hole is formed in the center of the body, wherein a piston rod penetrates the through hole. An inclined plane is arranged at one side of the body. The inclined plane is connected with a cylinder tube of a slant oil cylinder. In the process of moving of a forklift, the shock absorption block fills up a gap between the piston rod and the cylinder tube of the slant oil cylinder, and thereby a fixed support is arranged at the lower side of the piston rod which is connected with a goods shelf, and shock of the piston rod and the goods shelf is reduced and falling of goods on the goods shelf is not prone to dropping. In addition, a lock nut of the piston rod is not prone to being loose after shock is absorbed, radial rotation of the piston rod is avoided, effective work portion of the piston rod is not prolonged, the slant oil cylinders at two sides of the forklift are always synchronous when the slant oil cylinders work and stress is even, and thereby service life of the forklift is prolonged.
Description
Technical field:
The utility model relates to a kind of tilting oil cylinder of fork mechanism technology field, relates in particular to a kind of snubber block for tilting oil cylinder of fork mechanism.
Background technology:
Fork truck is when work, in order to pitch rapidly and easily the picking thing, door frame need to turn forward, goods falls in order to prevent from transporting goods, need door frame to recede, these two actions are finished by the dump ram mechanism of fork truck, the cylinder tube of dump ram mechanism is articulated on the vehicle frame, one end of the piston rod of oil cylinder utilizes earrings to be connected with the lifting shelf, and bad because of self damping, condition of road surface is bad in addition, in the fork truck driving process, the vibration of lifting shelf can cause that the goods on the shelf drops on the one hand, can cause that on the other hand the jam nut on the piston rod occurs loosening, cause the radial rotating of piston rod, the effective working portion of piston rod is elongated, and is asynchronous when the dump ram of fork truck both sides is worked, and causes unbalance stress, cause the larger piston rod head fracture of bearing capacity, and then caused shutdown maintenance, and delayed production, increased service expenditure and the productive costs of fork truck.
The utility model content:
The technical problems to be solved in the utility model is the snubber block that is used for tilting oil cylinder of fork mechanism that the damping of a kind of energy is provided and can increases the service life.
For solving the problems of the technologies described above, the utility model has adopted a kind of like this snubber block for tilting oil cylinder of fork mechanism: it comprises body, described body center is provided with the through hole that passes for piston rod, and described body one side also is provided with the inclined-plane, and described inclined-plane is connected with the cylinder barrel of dump ram.
Also be provided with first step and second step on the described body, described first step is arranged at body one side and is connected with through hole one end, and described second step is arranged at the body opposite side and is connected with the through hole other end.
The diameter of described first step is greater than the diameter of second step.
After adopting above structure, the utility model compared with prior art, have the following advantages: it comprises body, described body center is provided with the through hole that passes for piston rod, described body one side also is provided with the inclined-plane, described inclined-plane is connected with the cylinder barrel of dump ram, and also be provided with first step and second step on the described body, described first step is arranged at body one side and is connected with through hole one end, described second step is arranged at the body opposite side and is connected with the through hole other end, in the fork truck driving process, snubber block is filled up the space between piston rod and cylinder tube, so that be connected with the piston rod downside of shelf fixed pivot is arranged, to alleviate the vibrations of piston rod and shelf, can not cause that the goods on the shelf drops, can not cause after the damping that on the other hand the jam nut on the piston rod occurs loosening yet, can not cause the radial rotating of piston rod, the effective working portion of piston rod just can be not elongated, it is synchronous all the time when the dump ram of fork truck both sides is worked, cause stressed even, and then, prolonged service life of fork truck.
As preferably, the diameter of described first step is convenient to be used with cylinder tube and piston rod greater than the diameter of second step.
Description of drawings:
Fig. 1 is the structural representation of a kind of snubber block for tilting oil cylinder of fork mechanism of the utility model.
As shown in the figure: 1, body, 2, through hole, 3, the inclined-plane, 4, first step, 5, second step.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of snubber block for tilting oil cylinder of fork mechanism of the present utility model, it comprises body 1, described body 1 center is provided with the through hole 2 that passes for piston rod, described body 1 one sides also are provided with inclined-plane 3, described inclined-plane 3 is connected with the cylinder barrel of dump ram, be specially, be supported on the surface of cylinder barrel, in addition, also be provided with first step 4 and second step 5 on the described body 1, described first step 4 is arranged at body 1 one sides and is connected with through hole 2 one ends, and described second step 5 is arranged at body 1 opposite side and is connected with through hole 2 other ends, piston rod socket described snubber block and tilting oil cylinder of fork, an end that is provided with second step 5 contacts with cylinder tube, and inclined-plane 3 is supported in the cylinder barrel surface, and an end that is provided with first step 4 is connected with the earrings junction with the piston rod of regaining in the fork truck driving process, plays a supportive role, because structural relation, the diameter of described first step 4 is greater than the diameter of second step 5.
Below only just the preferred plan of the utility model embodiment is described, can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure has allowed multiple variation, such as the shape of described body 1, as long as the variation in these claims is all within protection domain of the present utility model.
