As shown in fig. 4, the double-trolley double-beam bridge type hook crane 1 is arranged above the stacking bin 4, and the double-trolley double-beam bridge type hook crane 1 includes a bridge structure 1.1, a hoisting mechanism 1.2 and a running mechanism 1.3.

The double-trolley double-beam bridge type hook crane 1 can move back and forth along the length direction of the stacking bin 4 through the running mechanism 1.3; two sets or multiunit hoisting mechanism 1.2 (wire rope winding system) are still equipped with in addition on two dolly two roof beam bridge type lifting hook hoist 1, and hoisting mechanism 1.2 can accomplish the lift lifting to hanging portable harrow sword machine 2.

The double trolley double beam bridge hook crane 1 here is designed:

the static rigidity of the hoisting mechanism 1.2 is: the vertical static deflection caused by the closest distance between two trolleys in the main beam span by the rated lifting load and the self weight of the trolley meets the following requirements: the A1-A3 grade is not more than S/700, the A4-A6 grade is not more than S/800, and the A7 grade is not more than S/1000.

The dynamic rigidity of the hoisting mechanism is as follows: when the trolley is positioned in the midspan, the full-load natural vibration frequency of the main beam is not less than 2 HZ.

The model that two dolly double beam bridge type lifting hook hoist 1 chose for use does: QD15+ 15T-22.5M.

As shown in fig. 2 and 5, a suspended mobile rake 2 is arranged in the middle of the double-trolley double-beam bridge type hook crane 1, and the suspended mobile rake 2 can realize ascending or descending movement under the combined action of the lifting device 2.7 and the rake freedom device 2.3, and can also realize back and forth reciprocating movement with the double-trolley double-beam bridge type hook crane 1 along the length direction of the warehouse and keep stable in the operation process.

In particular, the lifting device 2.7 here comprises two sets of pulley assemblies 7, one set near each of the head and tail wheel assemblies 2.2, 2.6. The steel wire rope 8 is tightly sleeved on the pulley component 7, the other end of the steel wire rope is connected with the hoisting mechanism 1.2 in the double-trolley double-beam bridge type hook crane 1, the steel wire rope winding system in the hoisting mechanism 1.2 is matched to act, the synchronous ascending or descending of the suspended movable type harrow cutter machine 2 can be realized through the PLC intelligent control system, and the descending height can be adjusted by controlling the driving time of the hoisting mechanism 1.2.

As shown in fig. 6, specifically, the rake cutter machine freedom device 2.3 includes a guide column frame 2.3.2, a fixed disk 2.3.1 is welded at the top end of the guide column frame 2.3.2, and the rake cutter machine freedom device 2.3 is hinged on the double-trolley double-beam bridge-type hook crane 1 through the fixed disk 2.3.1. An upper and lower guiding and anti-rotation device 2.3.3 is arranged in the middle of the guiding upright post frame 2.3.2, the front end of the upper and lower guiding and anti-rotation device 2.3.3 is sleeved on the guiding upright post frame 2.3.2 and can slide up and down along the guiding upright post frame 2.3.2, and the tail end of the upper and lower guiding and anti-rotation device 2.3.3 is fixedly connected with the suspended movable harrow cutter machine 2. The bottom end of the guide upright post frame 2.3.2 is welded with a front and back guide and anti-swing device 2.3.4, and the front and back guide and anti-swing device 2.3.4 moves back and forth along a steel rail 23 on the ground, so that the suspended movable scraper knife machine 2 is ensured to move back and forth in parallel in the warehouse along with the crane 1.

The upper and lower guiding and anti-rotation device 2.3.3 mainly comprises a pair of guiding rollers 18 (the structure of the roller is similar to a spherical dumbbell, the radian of the spherical surface is matched with the radius of a steel pipe of a column frame), two ends of the roller are arranged on a connecting plate 19 through self-aligning roller bearings, and one side of the connecting plate 19 is connected with the suspended movable harrow cutter machine 2.

The functions of the upper and lower guiding and anti-rotation device 2.3.3 are: 1) the guide roller 18 moves up and down along the upright post frame 2.3.2, and plays a role in guiding the up-and-down lifting process of the suspended movable harrow cutter machine 2. Because the steel wire ropes of the traction members are flexibly connected, when a pair of steel wire ropes on the left side and the right side are asynchronous in the up-and-down lifting process of the suspended movable harrow cutter machine 2, the suspended movable harrow cutter machine 2 slightly rotates around the Y axis; when the front and rear pair of wire ropes are out of sync, there will be a slight rotation of the suspended mobile raker 2 about the X axis. When any of the above occurs, the upper and lower guiding and anti-rotation devices 2.3.3 can not only prevent the rotation of the suspended movable type harrow blade machine 2, but also compensate the displacement caused by the slight rotation due to the adjustment amount of the self-aligning roller bearing.

Description of the drawings: if the adjustment compensation of the self-aligning roller bearing is not available, the fixed disc 2.3.1 can be easily twisted off by hanging the movable scraper knife machine 2 by adopting rigid connection, and the bridge frame of the crane is damaged by twisting in severe cases.

The front and back guide and anti-swing device 2.3.4 mainly comprises two pairs of walking rollers 20, the walking rollers 20 are arranged on a support plate 21, and the support plate 21 is fixedly connected with the upright post frame 2.3.2.

The front and back guide and anti-swing device 2.3.4 has the following functions: because the steel wire rope of the traction component is in flexible connection, the suspended movable harrow cutter machine 2 can swing left and right very possibly. Because the top end of the upright post frame 2.3.2 is hinged, the upright post frame can swing along with the top end of the upright post frame. The two pairs of running rollers 20 closely attached to the rails 23 clamp the rails 23 from left to right, thereby preventing the occurrence of the swing phenomenon.

Through being connected the direction column frame 2.3.2 upper end and the articulated of two dolly two roof beam bridge type lifting hook hoist 1, the lower extreme moves along the rail, has ensured like this that hang portable harrow sword machine 2 and along with two dolly two roof beam bridge type lifting hook hoist 1 parallel translation in the warehouse together. Meanwhile, the swinging phenomenon caused by micro-shaking of the suspended movable harrow cutter machine 2 in the moving process is avoided.

By sleeving the suspended movable harrow cutter machine 2 with the guide upright post frame 2.3.2, the suspended movable harrow cutter machine 2 can only move up or down along the guide upright post frame 2.3.2 and can not rotate around the guide upright post frame 2.3-2. But the upper and lower guiding and anti-rotation means 2.3.3 have a compensating function when the lifting means 2.7 are slightly out of synchronism.

The suspended mobile rake 2 is mainly used to spread out the bagasse during the stacking stage and to discharge the bagasse out of the silo during the discharge.

As shown in fig. 6-7, the suspended mobile raker 2 includes a raker housing 2.5, a head pulley assembly 2.2 and a tail pulley assembly 2.6 are disposed in the raker housing 2.5, a double-row scraper chain 2.4 is mounted on the head pulley assembly 2.2 and the tail pulley assembly 2.6, and the scraper chain 2.4 is driven by a driving unit 2.1.

Specifically, the driving unit 2.1 is composed of a motor and a speed reducer. The PLC intelligent control system changes the speed of the suspended movable type harrow cutter machine 2 by modifying the frequency value of the frequency converter in the driving unit, thereby realizing automatic adjustment of the conveying capacity of the suspended movable type harrow cutter machine 2.

When the motor is overloaded and the oil temperature of the speed reducer exceeds the standard and other faults occur, the audible and visual alarm acts, and the PLC control system can control the motor to automatically stop after time delay; when the audible and visual alarm is deactivated, the PLC intelligent control system can control the motor to be automatically started.

The head pulley assembly 2.2 comprises head pulleys which are used in pairs and are arranged on both sides of the drive shaft. The drive shaft is mounted on the raker blade housing 2.5 by means of a bearing assembly. The drive shaft is connected to the drive unit 2.1 via a chain drive. The bearing in the bearing assembly is a tapered roller bearing, and the tapered roller bearing has an automatic aligning function and can bear large bending moment and torque.

In order to reduce the running noise of the rake conveyor, the linear speed of the head wheel is not more than 0.5 m/s. When the running noise of the harrow cutter machine exceeds 85 db, the PLC intelligent control system can automatically reduce the speed of the harrow cutter machine; when the noise of the scraper blade machine in operation is less than 75 db, the PLC intelligent control system can automatically increase the speed of the scraper blade machine.

The noise is measured by a multifunctional noise analyzer with model number HS6288E

Due to the adoption of the roller chain, the sliding friction generated by the traditional chain transmission is converted into rolling friction in the running process, so that the dragging power of the scraper chain 2.4 is reduced, and the design width of the device can be indirectly improved. The width of the traditional buried scraper conveyor is limited by the chain dragging power, and can not exceed 1.25 meters at most, while the width of the buried scraper conveyor can reach 2 meters.

As shown in fig. 11-12, the rake blade 2.4.2 includes a rake blade fixing beam 11, cleaning rake blades 12 are disposed at the left and right ends of the rake blade fixing beam 11, scraping rake blades 13 are uniformly disposed between the two cleaning rake blades 12 at equal intervals, and the cleaning rake blades 12 and the scraping rake blades 13 are fixed on the rake blade fixing beam 11 by welding.

The sweeping harrow blades 12 and the scraping harrow blades 13 are all right-angled trapezoids, and the two sweeping harrow blades 12 are outwards opened to form an outwards splayed shape. Here the rake blades have directionality: in the bearing section, the blade tips (forward) of the sweeping rake blade 12 and the scraping rake blade 13 point to the bagasse conveying direction; the blade tips (downwards) of the sweeping rake blade 12 and the scraping rake blade 13 point to the height direction of the bagasse pile. The principle of cutting the vegetables is the same as that of a kitchen knife, and the bagasse conveying device can be quickly inserted into bagasse to convey the bagasse.

As shown in fig. 13-15, the raker housing 2.5 comprises a head housing 2.5.1, a middle housing 2.5.2 and a tail housing 2.5.3, wherein the head housing 2.5.1 is assembled with a driving unit 2.1, a head wheel assembly 2.2 and the tail housing 2.5.3 is assembled with a tail wheel assembly 2.6. The middle housing 2.5 is fitted with a scraper chain 2.4.

The upper and lower parts of the middle shell 2.5.2 are respectively provided with an upper track 14, a lower track 15, and the no-load section and the bearing section of the double rows of scraper chains 2.4 are respectively arranged on the upper track 14 and the lower track 15. Here the lower end of the truss structure is an open structure and the drag blade 2.4.2 part of the drag chain 2.4 extends out of the lower end of the truss structure. The material (bagasse) thus conveyed does not enter the interior of the intermediate housing, the conveyor chain 2.4.1 is completely free from contact with the bagasse, and since the conveyor chain 2.4.1 is a roller chain, the rolling friction of the conveyor chain 2.4.1 is rolling friction.
