Description

Lifting guide rod type continuous chain bucket ship unloader model structure
Technical Field
The invention relates to the technical field of continuous ship unloader, in particular to a lifting guide rod type continuous chain bucket ship unloader model structure.
Background
The continuous ship unloader is a model which meets the development requirements of environmental protection and environmental protection of wharfs. The chain bucket is adopted to excavate and lift the materials, so that the unloading method is a ship unloading method which can take most of bulk cargo types into consideration, and particularly the problem of unloading bulk cargo materials with large volume and poor fluidity can be solved.
The L-shaped chain bucket ship unloader (figure 20) is the most mature and widely used type of continuous chain bucket ship unloader at present. The device is characterized in that a chain bucket lifting system is used for excavating and lifting materials in a cabin, an arm support is used for pitching and adjusting the operation height of a material taking head, the arm support is used for rotating and adjusting the horizontal operation position of the material taking head in cooperation with a cart running (shown in figure 22), and the chain bucket lifting system is used for driving the material taking head to rotate, excavate and take materials (shown in figure 21).
The bulk cargo wharf in Yangtze river basin is mainly characterized in that ships are small and medium in size, the ship size is small, the hatch is small, the wharf mainly adopts a vertical high-pile wharf, the water level drop is very large, and the maximum water level change can reach 30-40m. The continuous bucket chain ship unloading equipment has the main difficulties that the shape of a material taking head for operation in a cabin and the space required by operation cannot be too large so as to facilitate the operation in and out of a hatch and in the cabin, and the operation height of the bucket chain material taking head can be greatly adjusted to adapt to the change of the water level of a wharf.
The L-shaped chain bucket ship unloader has the operating characteristic that the L-shaped chain bucket ship unloader cannot be applied to ship unloading operation of bulk cargo wharfs in Yangtze river basin. The reason is that:
(1) As shown in fig. 20, the working height of the material taking head of the L-shaped chain bucket ship unloader cannot be adjusted greatly due to the limited pitching angle of the arm frame, so that the working requirement of the vertical high pile wharf with a great water level difference cannot be met.
(2) As shown in fig. 21, the material taking head of the l-shaped chain bucket ship unloader adopts a rotary material taking mode, and the rotary movement direction of the material taking head is perpendicular to the movement direction of the chain bucket under the traction of the chain. Therefore, the material enters the chain bucket from the side angle of the chain bucket, and the speed of entering the chain bucket is slower. To ensure the ship unloading productivity, the bucket is narrow and deep, and the length L 2 of the material taking head is large, so that the material can enter in enough time and can fill the bucket. The chain bucket with a deep shape is easy to accumulate materials and difficult to empty. The large-length material taking head rotates to take materials, so that the working radius is large, and when the small and medium bulk cargo ship with smaller ship width is taken in and taken out, the operation is very inconvenient, and even the bulk cargo ship cannot be accommodated in a cabin.
(3) As shown in fig. 20 and 22, the L-shaped chain bucket ship unloader adopts the boom pitching and turning to adjust the operation point of the material taking head in cooperation with the traveling of the large truck, mainly uses fixed-point rotary motion, has low motion speed and mutual influence between motions, is difficult to realize automatic operation, and is easy to interfere and limit mutually when a plurality of devices jointly receive and unload a ship, so that the improvement of the ship unloading efficiency of the whole ship is influenced.

Compared with the prior art, the invention has the following technical advantages:
(1) The special operation requirement of large water head can be met through the secondary relay lifting operation of the chain bucket material taking arm and the telescopic bucket elevator. All ship unloading links are closed, no dust is leaked, and the environmental protection performance in the operation process can be ensured.
(2) The trolley with the chain bucket material taking arm walks on the L-shaped arm support to cover the operation width of the cabin, the arm support lifting steel wire rope lifts the L-shaped arm support, the material taking head operation height can be adjusted, the trolley walks along the quay shoreline, and the ship unloading operation position can be adjusted.

When a plurality of ship unloader jointly unload the ship operation, do not interfere each other, can improve whole ship and unload ship operating efficiency.
(3) The material taking head can continuously take materials in a reciprocating manner under the cooperation of trolley running. The chain bucket is always used for digging and taking materials right in front of the moving direction of the trolley. The front face of the bucket blade opening of the chain bucket is used for cutting materials, the operation efficiency is high, the length L 1 of the material taking head does not participate in the material digging operation, the appearance is compact, the operation radius is small, and the operation can be performed in a cabin with a narrower ship width, so that the problem of continuous ship unloading of small and medium bulk carriers is solved.
(4) The L-shaped arm support can be lifted by the arm support lifting steel wire rope and the pulley system. The guide rod moves along with the L-shaped arm support through the hinge shaft. The roller on the guide frame ensures the accuracy and convenience of the vertical movement of the guide rod. The novel structural form solves the problem of large-scale adjustment of the height position of the L-shaped arm frame. The movement direction of the movable counterweight is opposite to that of the L-shaped arm support, the movable counterweight is used for balancing the weight of the L-shaped arm support assembly, the trolley and the chain bucket material taking arm, and energy consumption in the process of adjusting the operation height of the material taking head in the operation process is reduced, so that energy conservation is realized.

The length of the lifting steel wire rope of the bucket elevator is adjusted along with the lifting of the L-shaped arm support, so that the total number of chain hoppers of the telescopic bucket elevator is unchanged. The telescopic chain bucket cover can be sealed and folded, and dust is prevented from leaking. The novel telescopic bucket elevator is a key point that the chain bucket ship unloader can realize secondary lifting.
(6) An upper rail and a lower rail are laid on the L-shaped arm support. During operation, the trolley wheels walk on the upper rail, and the trolley counter-rollers reversely support the lower rail to roll.

(7) The trolley frame is provided with a bracket, and the chain bucket material taking arm is arranged on the movable frame. The steel wire rope of the material taking arm works, and the movable frame is lifted and lowered along the support through the guide wheel. Under the operation state, the movable frame is at the lowest position, so that the unloading continuity can be ensured. When the ship is not in operation, such as the limitation of the water level and the ship shape, the material taking head can not be taken out of the bin, and the L-shaped arm support and the chain bucket material taking arm can be lifted to the highest position at the same time, so that the problems of switching the ship unloading operation point and ship leaving and berthing are solved.
(8) The whole machine has reasonable structure, the running range of the trolley can be ensured to cover the width of the operation cabin by the aid of the front sea arm support and the L-shaped arm support, and the length of the guide rod and the guide frame enables the L-shaped arm support to have enough lifting distance so as to ensure the height adjustment range of the working point of the material taking head of the chain bucket. The fixed counterweight and the machine room on the land side balance arm support can balance the weight of all sea side parts, so that the synthetic gravity center of the rotary part is close to the center of the rotary large bearing, the power of the rotary mechanism is reduced, the wheel pressure of the large wheel is balanced, and the load on the code head is reduced.
(9) In the non-operation state, the rotary mechanism drives the rotary platform to drive the central upright post and all the components attached to the central upright post to rotate around the center of the rotary large bearing. The L-shaped arm support and the fixing structure can be rotated to be parallel to a quay line, so that a ship can conveniently leave the quay, and the chain bucket material taking arm and the telescopic chain bucket lifting machine can be conveniently maintained. The problem that the continuous ship unloader has more parts and high maintenance requirements can be solved.

As shown in fig. 14, the material taking head excavates the material right in front of the traveling direction of the trolley, and the material taking line is formed in cooperation with the traveling of the trolley. The section of the length L 1 of the material taking head does not participate in the material digging operation, and the chain bucket realizes steering after stably digging the material, and the cleaning stage contacts the bilge to assist in cleaning. The length L 1 of the take-off head is therefore comparatively small. The compact and small material taking head can be used for operation in a cabin with a narrower ship width, and is particularly suitable for small and medium bulk carriers in Yangtze river basin.
