Abstract

The invention discloses a push-and-pull device of a ferry vehicle. The push-and-pull device comprises a rack. The two sides of the bottom face of the rack are supported on a walking track through side wheels. A push-and-pull rod which is capable of moving in the rack in a reciprocating mode is arranged in the rack. The push-and-pull device further comprises push-and-pull blocks which are arranged in a spaced mode. The push-and-pull blocks are hinged to protruding blocks on the top face of the rack. Every two adjacent push-and-pull blocks are arranged in a mirror symmetry mode. The top face of the push-and-pull rod is evenly provided with a plurality of sets of tooth-shaped grooves. The two push-and-pull blocks arranged adjacently make contact with each other at the highest ends of the adjacent tooth-shaped grooves. The push-and-pull device of the ferry vehicle is simple in structure, convenient to manufacture, capable of easily completing conversion between pushing and pulling, low in manufacturing cost and applicable to wide popularization and application.

Description

A kind of push-pull device at fixed of ferry bus

Technical field

The present invention relates to a kind of push-pull device at fixed, be specifically related to a kind of push-pull device at fixed of ferry bus.

Background technology

At the scene of some automated production operations, in order to save production site, conventionally have many manufacturing line arrangement in parallels.Between adjacent manufacturing line, need sometimes to use a transloading equipment, the action of this transloading equipment is all periodically back and forth carried out conventionally, is similar to the intercoastal ship of rivers and back and forth ferries, so be commonly referred to ferry bus.

Push-pull device at fixed is a kind of device being used on ferry bus, traditional push-pull device at fixed has two kinds: the first can only realize that single promotion is done or the single work that pulls, in reality is produced, be not well positioned to meet need of production, the time standby propelling unit that can only push away, when drawing mainly by artificial; Although the second push-pull device at fixed can meet the demands, both can push away also and can draw, but the conversion of his push pull maneuver realizes by oil cylinder and hydraulic oil unit, the locus that hydraulic oil unit takies is larger, price is higher comparatively speaking, has greatly increased production cost.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, with low cost, push-and-pull to be applied in easily the push-pull device at fixed on ferry bus.

A push-pull device at fixed on ferry bus, comprises frame, and both sides, described frame bottom surface are bearing on walking track by side wheel, are provided with the pull bar that can move back and forth in described frame within it; Push-pull device at fixed on described ferry bus comprises the push-and-pull piece that is gap arrangement, described push-and-pull piece is hinged on the projection of frame end face, two push-and-pull pieces of adjacent setting are mirror image and are symmetrical arranged, described pull bar end face evenly offers multiple sets of teeth shape groove, and two push-and-pull pieces of described adjacent setting touch the most significant end at adjacent serrate slot.

Described pull bar drives by being connected to the electric pushrod of its one end, realizes moving back and forth in frame.

The present invention is simple in structure, easy to make, can realize easily the conversion of push-and-pull work, and cheap for manufacturing cost, is applicable to applying on a large scale.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

Embodiment 1

Referring to Fig. 1, push-pull device at fixed on a kind of ferry bus provided by the invention, comprise frame 1, described frame 1 both sides, bottom surface are bearing on walking track by side wheel 2, and ferry bus (figure does not mark) hauls this push-pull device at fixed by chain transmission system and moves back and forth on walking track.

In described frame 1, be provided with pull bar 3, this pull bar 3 drives by being connected to the electric pushrod 4 of its one end, realizes the reciprocal operation in frame 1; Push-pull device at fixed on described ferry bus comprises the push-and-pull piece 5 that is gap arrangement, described push-and-pull piece 5 is hinged on the projection 6 of frame 1 end face, two push-and-pull pieces 5 of adjacent setting are mirror image and are symmetrical arranged, described pull bar 3 end faces evenly offer multiple sets of teeth shape groove 7, and two push-and-pull pieces 5 of described adjacent setting touch the most significant end at adjacent serrate slot 7.

Referring to Fig. 1, when electric pushrod 4 keeps virgin state, first and third, five push-and-pull piece 5 perks from left to right, second, four, six push-and-pull piece 5 maintenance levels, now can be used for pushing away moulding box;

When electric pushrod 4 is released, first and third, five push-and-pull pieces 5 are level gradually, and second, four, six push-and-pull piece 5 perks now can be used for drawing-die case.

Claims

1. the push-pull device at fixed on a ferry bus, comprise frame, both sides, described frame bottom surface are bearing on walking track by side wheel, in described frame, be provided with the pull bar that can move back and forth within it, it is characterized in that: the push-pull device at fixed on described ferry bus comprises the push-and-pull piece that is gap arrangement, described push-and-pull piece is hinged on the projection of frame end face, two push-and-pull pieces of adjacent setting are mirror image and are symmetrical arranged, described pull bar end face evenly offers multiple sets of teeth shape groove, and two push-and-pull pieces of described adjacent setting touch the most significant end at adjacent serrate slot.

2. the push-pull device at fixed on a kind of ferry bus according to claim 1, is characterized in that: described pull bar drives by being connected to the electric pushrod of its one end, realizes moving back and forth in frame.
