Abstract
The invention discloses a rubber ram for a cable festoon. The rubber ram comprises a rubber column, wherein the rubber column is provided with a sliding cavity, and the sliding cavity is internally provided with a piston rod; the piston rod is provided with a copper ball, and the piston rod is sleeved with an elastic rubber sleeve positioned between the rubber column and the copper ball. The rubber ram provided by the invention has the advantages that the structure is simple, the manufacture is easy, a buffering effect is good, and the service life is long.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, relate in particular a kind of rubber for cable trailing and ram.
Background technology
The patent openly number of announcement is CN 102718142A, open day: the Chinese invention patent of 2012-10-10 discloses a kind of cable trailing, comprise the supporting plate for load-bearing cable, the described supporting plate support that is connected, each side of described support is all connected with two baffle plates, the described baffle plate that is positioned at support both sides is parallel to each other, on described every baffle plate, be all connected with road wheel, the described road wheel positioned opposite that is positioned at support both sides, on described baffle plate, be also connected with trailing arm, described trailing arm is provided with track adjusting wheel, the described track adjusting wheel that is positioned at support both sides is arranged in pairs, two pairs of described track adjusting wheels lay respectively at the two ends of two pairs of road wheels.This invention for prevent whole drag order clashed into, be provided with elastic buffer piece, cushion, but, the elastic buffer piece of its setting is suitable for than relatively large cable trailing, and for smaller cable trailing, now just adopts common rubber column as buffering, its buffering effect is poor, and service life is limited.
Summary of the invention
The object of this invention is to provide for the deficiencies in the prior art part, provide a kind of rubber for cable trailing to ram, can overcome the deficiencies in the prior art part, it is simple in structure, easy to manufacture, good buffer effect, and the life-span is long.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: the rubber for cable trailing is ramed, comprise rubber column, described rubber column is provided with sliding cavity, in described sliding cavity, be provided with piston rod, described piston rod is provided with copper ball head, and described upper cover of piston rod is equipped with elastic caoutchouc cover between described rubber column and described copper ball head.
As preferably, the diameter of described piston rod is the 1/4-1/3 of described rubber column diameter.
As preferably, the elasticity arc plate of a plurality of mutual stacks of described sliding cavity.
As preferably, described elasticity circular arc plate thickness is 0.5-1mm.
As preferably, described copper ball cephalic par is provided with copper ball head, and described copper ball head is provided with a plurality of pits.
As preferably, described pit cross-sectional plane is circular arc.
As preferably, described elasticity arc plate quantity is 3-10.
As preferably, described elastic caoutchouc cover length is 3-5mm.
Beneficial effect of the present invention is:
Simple in structure, easy to manufacture, good buffer effect, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.
Embodiment, see accompanying drawing 1, 2, rubber for cable trailing is ramed, comprise rubber column 1, rubber column is cylindrical, by hard rubber, made, on described rubber column 1, be provided with sliding cavity 2, an end face of sliding cavity 2 and rubber column communicates, in described sliding cavity 2, be provided with piston rod 3, the diameter of piston rod 3 is 1/4-1/3 of rubber column 1 diameter, piston rod is rod iron or copper rod, can not ether thick, wherein take rod iron as good, described piston rod 3 is provided with copper ball head 4, described copper ball head 4 ends are provided with copper ball head, described copper ball head is provided with a plurality of pits 6, described pit 6 cross-sectional planes are circular arc, because copper is relatively soft, after multiple impact, the part of distortion can enter in pit, make the whole maintenance of copper ball head there is no large variation, guarantee buffering effect.
Simultaneously, on described piston rod 3, be set with elastic caoutchouc cover 5 between described rubber column 1 and described copper ball head 4, elastic caoutchouc cover can play the effect of buffering, when copper ball head is subject to impacting, power can be by elastic caoutchouc cover buffering, and it is 3-5mm that elastic caoutchouc overlaps 5 length.
Further, in order to increase buffering effect, more than 2 elasticity arc plates 7 that mutually superpose of described sliding cavity, described elasticity arc plate 7 thickness are 0.5-1mm, quantity is 3-10, by spring plate, is made, and wherein take 8 as good, the circular arc top of described elasticity arc plate 7 is with piston rod to contacting, and a plurality of described elasticity arc plates 7 further impact cushion.
More than explanation is only explanation of the invention, make those of ordinary skills' can completely implement this programme, but be not limitation of the present invention, those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this specification sheets, and these are all not creative modifications.But as long as within the scope of claim of the present invention, be all subject to the protection of patent law.
