Description

Anti-falling device for skip hoist

Technical Field

The utility model relates to a skip car is anticreep car device for skip car lifting machine belongs to skip car lifting machine safety protection technical field.

Background

The skip car hoister is a device which can lift materials to a certain height and then dump the materials into a bin of a device needing to be fed so as to complete feeding work, is mainly suitable for continuously and vertically lifting powdery, granular and small materials, and can be widely applied to lifting small bulk materials of food factories, feed factories, flour factories, rice factories, oil factories, starch factories, grain depots, port wharfs and the like in various scales.

Most no anticreep car device of traditional skip lifting machine, when the skip along with U-shaped fork motion to final upset position, because inertia, the skip has the potential safety hazard of following the U-shaped fork landing, and for this reason, part skip lifting machine is furnished with the anticreep car device, nevertheless, current anticreep car device is mostly spring resilient means, and the structure is complicated, easily enters into foreign matter such as dust, the sanitary work of being not convenient for, cause food potential safety hazard, and the cost of manufacture is high, and the fault rate is higher.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the utility model provides a simple structure, cost of manufacture are low, the low anticreep car device for skip car lifting machine of fault rate.

Skip is anticreep car device for hoist, including the outer sleeve, sliding connection has the inner skleeve in the outer sleeve, the inner skleeve embeds there is can be at its inside gravity piece that freely slides, the top that stretches out the outer sleeve on the inner skleeve is fixed with the overhead gage, the bottom that stretches out the outer sleeve of the lower extreme of inner skleeve is fixed with down the baffle, the diameter of baffle and overhead gage all is greater than the internal diameter of outer sleeve down.

The transverse sections of the outer sleeve and the inner sleeve are circular, the gravity blocks are spherical, the gravity blocks can be steel balls, and the two gravity blocks can be arranged as required, so that the overall operation stability of the structure is better.

Elastic pads corresponding to the outer sleeves are fixed at the bottom of the upper baffle and the top of the lower baffle, and the elastic pads can be silica gel pads, so that rigid collision between the upper baffle and the outer sleeves and between the lower baffle and the outer sleeves can be effectively buffered, and a protection effect is achieved.

Compared with the prior art, the utility model beneficial effect who has is:

skip hoist for anticreep car device, simple structure, low price, simple to operate, non-maintaining can effectually avoid the skip slippage, improved the security performance of skip hoist.

FIG. 3 is a schematic diagram of a motion trajectory in application of the present invention;

fig. 4 is a schematic diagram of a state in which the present invention is applied.

In the figure: 1. a lower baffle plate; 2. an elastic pad; 3. an inner sleeve; 4. an outer sleeve; 5. an upper baffle plate; 6. a gravity block; 7. a U-shaped fork; 8. skip car lifting machine.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in fig. 1 and 2, skip hoist is with anticreep car device, including outer sleeve 4, sliding connection has inner skleeve 3 in the outer sleeve 4, the inner skleeve 3 embeds there is can be at its inside free gliding gravity piece 6, the top that the outer sleeve 4 was stretched out to the upper end of inner skleeve 3 is fixed with upper baffle 5, the lower extreme of inner skleeve 3 stretches out the bottom of outer sleeve 4 and is fixed with baffle 1 down, baffle 1 all is greater than the internal diameter of outer sleeve 4 with the diameter of upper baffle 5 down.

When in use, the outer sleeve 4 of the utility model is fixed on the fork opening lower wall of the U-shaped fork 7 of the skip car hoister 8, as shown in figure 3, at this time, the U-shaped fork 7 is at the initial position a, the inner sleeve 3 is at the lowest end under the action of gravity of the gravity block 6, the skip car is not obstructed from entering the U-shaped fork 7, after the skip car is smoothly pushed into the U-shaped fork 7, the skip car hoister 8 moves to drive the U-shaped fork 7 to move upwards, when the U-shaped fork 7 moves to the position b, the U-shaped fork 7 starts to drive the skip car to turn over, when turning over to the position of figure 4, the lower baffle 1 is level with the upper baffle 5, at this time, the U-shaped fork 7 continues to drive the skip car to turn over, so that the lower baffle 1 is higher than the upper baffle 5, therefore, the gravity block 6 slides to the upper baffle 5 under the action of self gravity to drive the inner sleeve 3 to move to seal the fork opening of the U-shaped fork 7, therefore, when the skip car moves to the final turning position c, the skip slippage phenomenon can not occur.

In a preferred embodiment: the transverse sections of the outer sleeve 4 and the inner sleeve 3 are both circular, the gravity block 6 is spherical, the gravity block 6 can be made of steel balls, and two gravity blocks can be arranged as required, so that the integral operation stability of the structure is better; the elastic pads 2 corresponding to the outer sleeves 4 are fixed at the bottom of the upper baffle 5 and the top of the lower baffle 1, and silica gel pads can be adopted as the elastic pads, so that rigid collision between the upper baffle 5 and the outer sleeves 4 and between the lower baffle 1 and the outer sleeves 4 can be effectively buffered, and a protection effect is achieved.
