Description
Technical Field
The utility model relates to a hoist equipment field especially relates to a hoist for cylinder head.
Background
A lifting appliance refers to a device for lifting a heavy object in a lifting machine. The most common lifting devices for lifting finished articles are lifting hooks, lifting straps, lifting rings, lifting suction cups, clamps, forks and the like. Is widely applied to the hoisting industry. Traditional hoist adopts the clamp formula of getting or inserts the formula of getting to connect more, and when traditional hoist was used for the product of hoist and mount cylinder head, neither be convenient for connect, again because with product outward appearance direct contact, cause wearing and tearing easily to the product surface, influence product quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a hoist for cylinder head.
The utility model discloses a realize through following technical scheme:
a spreader for a cylinder head, comprising: a connecting plate, a clamping jaw and a limiting mechanism,
two guide long holes are symmetrically arranged on the connecting plate, the guide long holes are divided into a vertical part and an inclined part below the vertical part, guide rods are inserted into the guide long holes, two clamping jaws are arranged, the upper ends of the clamping jaws are fixedly connected with the guide rods in a one-to-one correspondence manner, the lower ends of the clamping jaws are fixedly connected with a supporting table,
the limiting mechanism comprises an inner sleeve fixedly connected to the lower end of the connecting plate, an outer sleeve sleeved on the inner sleeve and sliding along the inner sleeve, a limiting rod fixedly connected in the inner sleeve and a positioning sleeve fixedly connected with the lower end of the outer sleeve and provided with an opening at the lower part, connecting fins are symmetrically and fixedly connected to two sides of the outer sleeve, and the connecting fins are hinged to the middle parts of the clamping jaws on the same side.
Preferably, the lower end of the supporting table is provided with a guide inclined plane, and when the lifting appliance descends, the lower end of the supporting table contacts the surface of a product, so that the clamping jaws are pushed away towards two sides.
Preferably, the lower end of the limiting rod is fixedly connected with a positioning end, and the upper end of the positioning sleeve is fixedly connected with a positioning groove corresponding to the positioning end.
The utility model has the advantages that:
the utility model provides a hoist need not artifical manually operation when the product that has the cylinder head is hoisted, can realize opening, pressing from both sides tightly of jack catch through the action of gravity is automatic, simple structure, reasonable in design, and convenient to use has improved work efficiency and stability greatly.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a left side view structure diagram of the present invention.
In the figure: 1. the device comprises a connecting plate, 2 jaws, 3 guide long holes, 4 guide rods, 5 support tables, 6 inner sleeves, 7 outer sleeves, 8 limiting rods, 9 positioning sleeves, 10 connecting fins, 11 guide inclined planes, 12 positioning end heads and 13 positioning grooves.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a: a connecting plate 1, a clamping jaw 2 and a limiting mechanism,
two guide long holes 3 are symmetrically arranged on the connecting plate, the guide long holes are divided into a vertical part and an inclined part below the vertical part, guide rods 4 are inserted into the guide long holes, two clamping jaws are arranged, the upper ends of the clamping jaws are fixedly connected with the guide rods in a one-to-one correspondence manner, the lower ends of the clamping jaws are fixedly connected with a supporting table 5,
the limiting mechanism comprises an inner sleeve 6 fixedly connected to the lower end of the connecting plate, an outer sleeve 7 sleeved on the inner sleeve and sliding along the inner sleeve, a limiting rod 8 fixedly connected in the inner sleeve and a positioning sleeve 9 fixedly connected with the lower end of the outer sleeve and provided with an opening at the lower part, connecting fins 10 are symmetrically and fixedly connected to two sides of the outer sleeve and hinged to the middle parts of the clamping jaws at the same side, when the guide rod is positioned at a turning point between the vertical part of the guide long hole and the inclined part, the distance between the two supporting platforms is not smaller than the outer diameter of the positioning sleeve, when the lifting appliance in the embodiment is used, the lifting appliance is driven by lifting equipment to descend, the lower end of the supporting platform is erected at the upper end of a product, the lifting appliance continues to descend, the supporting platform drives the clamping jaws to move upwards to enable the guide rod to move upwards, until the distance between two brace tables is greater than the external diameter of product upper end, the product upper end gets into in the position sleeve, the outer tube upwards slides along interior sleeve pipe, final position sleeve upper end offsets with the gag lever post lower extreme, the hoist no longer descends, accomplish opening and the location of jack catch, later upwards stimulate the hoist through the lifting means, the jack catch is under self action of gravity, drive the guide bar along direction slot hole downstream, two brace tables are close to each other, the brace table inserts terminal surface under the cylinder head of product, continue upwards to stimulate the hoist, because the action of gravity of product, the product can stimulate the brace table downwards, make the jack catch be in vertical state all the time, the jack catch presss from both sides tightly the cylinder head of product with the cooperation of brace table.
Preferably, the lower end of the supporting table is provided with a guide inclined plane 11, and when the lifting appliance descends, the lower end of the supporting table contacts the surface of a product, so that the clamping jaws are pushed away towards two sides, and the running stability is improved.
Preferably, the lower extreme rigid coupling of gag lever post has location end 12, the constant head tank 13 that the upper end rigid coupling of position sleeve has and fixes a position the end and correspond prevents to rock and take place the skew when making the hoist press from both sides tight product, leads to lifting by crane the process unstability.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
