Description

Technical Field

[0001] The utility model relates to the field of ship loaders, in particular to a linear moving ship loader. Background Art

[0002] Ship loaders are large bulk material machines used for loading at bulk material terminals. Generally, ship loaders are composed of arm belt conveyors, transition belt conveyors, telescopic chutes, tail cars, traveling devices, gantry, towers, pitch devices, slewing devices, etc. Large-scale port bulk material loading equipment plays an important role in the high-speed, stable, efficient and rolling development of some large bulk material distribution centers in the energy, power, metallurgy, ports and other industries. Ship loaders usually load continuously. Therefore, there must be supporting equipment to provide continuous material flow so that the ship loader can load continuously. Such as feeding grain silos at grain terminals and continuous feeding of bucket wheel reclaimers in the material yard of coal terminals.

[0003] However, the existing linear mobile ship loader generally adopts a longer bridge frame to realize material transportation. For example, Chinese patent CN202220112131.9 adopts a longer main beam quay bridge to realize longer material transportation. However, this type is mainly used for the transportation of containers and is not suitable for the transportation of powder or granular products.

[0004] Of course, there is also the use of Chinese patent CN202220112131.9, which realizes material transportation over a longer distance through the cooperation of the first rotating frame and the second rotating frame. However, this structure is larger in size after being folded, and the turning radius of the first rotating frame and the second rotating frame is limited (to ensure stable operation). Utility Model Content

[0005] The main purpose of the utility model is to propose a linear moving ship loader, aiming to improve the structure of the ship loader, thereby realizing the linear movement of the ship loader, and the volume after folding is small, has good resistance to abnormal climate, and effectively ensures the stability of use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a linear mobile ship loader, comprising:

[0007] A walking device, wherein a rotating device is provided on the upper wall of the walking device;

[0008] A tower base, the tower base is mounted on a rotating device, the rotating device can drive the tower base to rotate a predetermined angle, and a tower frame extends upward from the tower base;

[0009] A linearly movable arm, the linearly movable arm comprising a main arm and a telescopic arm slidably mounted on the main arm, the main arm being pivotally mounted on a tower base, the tower base being provided with a first driving device for driving the main arm to switch between a horizontally placed position and an upwardly swung position;

[0010] A sliding groove is provided in the middle of the main arm, the telescopic arm is installed in the sliding groove, and a second driving device for driving the telescopic arm to move linearly is provided at the rear end of the main arm;

[0011] A telescopic chute is detachably mounted at the rear end of the telescopic arm.

[0012] In the actual design, the walking device is set on a predetermined track to achieve horizontal movement. The slewing device can drive the telescopic chute to swing to a predetermined position, thereby improving the applicability of material transportation.

[0013] By setting a sliding groove in the middle of the main arm, the telescopic arm is more stable in use, so that the telescopic chute can transport materials within a predetermined range, and the walking device reduces a large range of moving stroke (requiring multiple mechanisms for adjustment). At the same time, when folding is required, the telescopic chute is first restored to the retracted state, and then the telescopic arm is extended into the sliding groove. Finally, the first drive device swings the linear movable arm upward as a whole, thereby realizing the overall equipment storage of the ship loader, facilitating the transportation of the overall equipment, and also reducing equipment damage caused by abnormal climate.

[0026] A walking device 1, wherein a rotating device 11 is provided on the upper wall of the walking device 1;

[0027] A tower base 2, wherein the tower base 2 is mounted on a rotating device 11, and the rotating device 11 can drive the tower base 2 to rotate a predetermined angle, and a tower frame 21 is extended upward from the tower base 2;

[0028] A linear movable arm 3, the linear movable arm 3 comprising a main arm 31 and a telescopic arm 32 slidably mounted on the main arm 31, the main arm 31 being pivotally mounted on the tower base 2, the tower base 2 being provided with a first driving device 41 for driving the main arm 31 to switch between a horizontally placed position and an upwardly swung position;

[0029] A sliding groove 33 is provided in the middle of the main arm 31, and the telescopic arm 32 is installed in the sliding groove 33. A second driving device 42 for driving the telescopic arm 32 to move linearly is provided at the rear end of the main arm 31;

[0030] The telescopic chute 5 is detachably mounted at the rear end of the telescopic arm 32 .

[0031] In the actual design, the walking device 1 is arranged on a predetermined track to realize horizontal movement, and the telescopic chute 5 can be driven to swing to a predetermined position through the slewing device 11, thereby improving the applicability of material transportation;

[0032] By setting a sliding groove 33 in the middle of the main arm 31, the telescopic arm 32 is more stable in use, so that the telescopic chute 5 can transport materials within a predetermined range, and the walking device 1 reduces a large range of moving stroke (requiring multiple mechanisms for adjustment). At the same time, when folding is required, the telescopic chute 5 is first restored to the retracted state, and then the telescopic arm 32 is extended into the sliding groove 33. Finally, the first drive device 41 swings the linear movable arm 3 upward as a whole, thereby realizing the overall equipment storage of the ship loader, facilitating the transportation of the overall equipment, and also reducing equipment damage caused by abnormal climate.

[0033] Specifically, the main arm 31 is a frame structure with a sliding groove 33 in the middle.

[0034] In the embodiment of the utility model, the sliding groove 33 is provided with a guide rail 61 distributed along its length direction, and the telescopic arm 32 is provided with a driving wheel 62 matched with the guide rail 61, wherein the second driving device 42 is a second steel rope pulley driving mechanism (this mechanism is a prior art and is not described here in detail), which can slide the telescopic arm 32 to a predetermined position, thereby realizing the movement of the telescopic arm 32, that is, utilizing the cooperation of the steel rope and the winding mechanism to realize the position adjustment of the moving part.

[0035] Furthermore, the second driving device 42 is a second steel rope pulley driving mechanism.

[0036] In the embodiment of the utility model, the first driving device 41 is arranged at the upper end of the tower 21, and the first driving device 41 is a first steel rope pulley driving mechanism. Through a longer arm distance, the swing fulcrum of the first driving device 41 is more stable when driving the main arm 31, thereby avoiding the workload of the first driving device 41. The principle is the structure of the lever principle.

[0037] Specifically, a telescopic rod 7 is installed between the middle part of the main arm 31 and the middle part of the tower 21, and both ends of the telescopic rod 7 are pivotally connected to the middle part of the main arm 31 and the middle part of the tower 21 respectively, and its length can be adjusted according to the distance between the main arm 31 and the tower 21.

[0040] Specifically, a support platform 8 is extended from the middle of the tower 21 in a direction away from the main arm 31, and the first driving device 41 is arranged on the support platform. The lever distance is further increased, thereby ensuring the swing stability of the main arm 31, so that even if the telescopic arm 32 exceeds the predetermined value, the weight of the telescopic arm 32 is less than the main arm 31, and the multi-support structure effectively ensures the working stability of the main arm 31.

[0041] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
