CN2923613Y - Anti-collision buffer for ship unloading machine - Google Patents

Abstract

The utility model discloses an anticollision buffer of the unloading ship machine, including a fixed base, a fixed cover, an expansion cover and buffering fillers, a plurality of multistage expansion segments are embedded with each other to form the expansion cover which is sleeved in the fixed cover and the fixed cover is fixed on the fixed base; the buffering fillers is filled in the cavity formed by the fixed cover and the expansion cover. The anticollision buffer of the unloading ship machine is used a multistage expansion segment structure and can decrease the transverse dimension of the buffer, increase longitudinal dimension of the buffer, enhance the anticollision flexibility, increase the buffering time and decrease the buffering force correspondingly through absorbing the collision energy by the buffering fillers thus to better protect the buffered articles. In some application case, the utility model can fully replace the hydraulic buffer and is economic and practical, reliable and secure.

Description

The ship unloaders crash cushions

Technical field

The utility model relates to the ship unloaders safety apparatus, more specifically refers to a kind of ship unloaders crash cushions, and this energy disperser is used to absorb unloads a ship machinery owing to clash into the energy that produces, and protects the safety of the machinery of unloading a ship.

Background technology

The energy disperser of being made as the buffering filler by polyurethane material generally is used for ship unloaders cart, dolly, harbour car bumper, and absorption is owing to clash into the energy that produces, the safety that it is mechanical that protection is unloaded a ship.But because polyurethane material, the scantling of structure of energy disperser is manufacturings in about 1: 1 according to asperratio generally, if longitudinal size is bigger, lateral dimension is less, be easy to when being subjected to force compresses fracture or roll inclined to one side, thereby lose or reduce buffer capacity.Yet, wish generally that as energy disperser cushion stroke is long, the object speed that is cushioned is reduced gradually, stop lentamente.Because the polyurethane material self character, the ratio of longitudinal size and lateral dimension can not be very big, results buffer flexible not enough.For requiring the long application scenario of cushion stroke, generally adopt water bumper.But water bumper price height, also leak easily, safeguard and also compare difficultly that quality is the domestic also dependence on import almost of failure-free water bumper very.

Summary of the invention

Design goal of the present utility model is to solve restricted, the unfavorable problem of buffering effect of aspect ratio that the conventional urethane energy disperser exists; a kind of ship unloaders crash cushions is provided; lateral dimension is reduced; longitudinal size increases; shock proof flexible the enhancing; surge time increases, and cushion effect reduces relatively, is cushioned object with strong protection.

For achieving the above object, the utility model has adopted following technical scheme:

This ship unloaders crash cushions comprises permanent seat, fixedly case, flexible case, buffering filler;

Described flexible case comprises by several slip joints and is embedded in one mutually, and the telescopic cover valve jacket is connected to fixedly in the case, and fixedly case is fixed on the permanent seat;

Described buffering filler fills in fixing case and the cavity that the telescopic cover hull shape becomes.

Similar and the stack vertically jointly of several slip joint shapes of described flexible case.

Described several slip joints are to change from small to big to root from the head.

The quantity of the slip joint of described flexible case is at least more than two.

In technique scheme of the present utility model, this ship unloaders crash cushions comprises permanent seat, fixedly case, flexible case, buffering filler, the case that will stretch comprises by several slip joints and is embedded in one mutually, and the telescopic cover valve jacket is connected to fixedly in the case, and fixedly case is fixed on the permanent seat; The buffering filler fills in fixing case and the cavity that the telescopic cover hull shape becomes.This ship unloaders crash cushions adopts multi-stage expansion joint structure, and utilizes the buffering filler to absorb the energy of bump, and the energy disperser lateral dimension is reduced; longitudinal size increases, shock proof flexible the enhancing, and surge time increases; cushion effect reduces relatively, has protected preferably to be cushioned object.In some application scenario, can replace water bumper fully, economical and practical, reliable and secure.

Description of drawings

Fig. 2 is a ship unloaders crash cushions sectional structure scheme drawing of the present utility model.

Fig. 3 is a sectional structure scheme drawing after ship unloaders crash cushions of the present utility model is impacted.

The specific embodiment

In order to understand technique scheme of the present utility model better, describe in detail further below in conjunction with drawings and Examples.

See also Fig. 1, shown in Figure 2, ship unloaders crash cushions of the present utility model comprises permanent seat 1, fixedly case 2, flexible case 3, buffering filler 4.

Described flexible case 3 comprises by several slip joints and is embedded in one mutually, and flexible case 3 is socketed on fixedly in the case 2, and fixedly case 2 is fixed on the permanent seat 1, offers mounting hole 5 on the permanent seat 1.

Described buffering filler 4 fills in the cavity that fixing case 1 and flexible case 2 form, and buffering filler 4 has adopted polyurethane material, and polyurethane material can absorbed the energy of external force after by the bump compression.

Similar and the stack vertically jointly of several slip joint shapes of described flexible case 2.

Described several slip joints are to change from small to big to root from the head, and the slip joint diameter of root forms a reducing Rotary-table that step is arranged greater than the diameter of the head that is impacted at first.

The quantity of the slip joint of described flexible case 3 is at least more than two, visual actual conditions and select how little, come adjusting shaft to length.

Fixedly case 2 and flexible case 3 are all selected the shell steel plate for use, and they play the framework effect of stable buffering filler 4.

See also shown in Figure 3, when energy disperser was subjected to impact along the F directive effect, the slip joint of flexible case 3 was pressed into fixedly in the case 2 successively, and each grade is not always the case, polyurethane buffering filler 4 in the case is compressed the energy that clashes into to absorb, thereby plays buffer action.Because this buffer buffers stroke is long, shock proof surge time is long, and impulsive force is little, is equivalent to a plurality of springs are connected in series, and has and the cooresponding effect of water bumper, and the lateral dimension of whole energy disperser is less.It is to be noted especially, each level of energy disperser is not long, otherwise in the compression process, 4 distortion of polyurethane buffering filler are inhomogeneous, will cause flexible case 3 in moving process, can not accurately be pressed into fixedly in the case 2 so that the stuck or phenomenon that rises brokenly occurs, this also is the major cause that adopts multilevel hierarchy.

Owing to adopt multilevel hierarchy, polyurethane is reduced as the energy disperser lateral dimension, longitudinal size increases, shock proof flexible the enhancing, surge time increases, and cushion effect reduces relatively, has protected effectively to be cushioned object.In some application scenarios, energy disperser of the present utility model can replace water bumper fully, and is inexpensive, economical and practical, reliable and secure.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
