Description

Technical Field

[0001] The present invention relates to the technical field of ship loaders, and particularly to a telescopic chute type ship loader. Background Art

[0002] A ship loader is a large bulk material handling machine used for loading ships at bulk material terminals. Large port bulk material loading equipment plays an important role in the high-speed, stable and rolling development of industries such as energy, power, metallurgy, ports, etc., especially in some bulk material distribution centers.

[0003] In the patent document with the authorization announcement number CN218707439U, an inland river slewing telescopic ship loader is disclosed. The ship loader includes a support frame, a dock belt conveyor, a slewing mechanism, a first belt conveyor and a second belt conveyor. The discharge end of the dock belt conveyor is arranged on the support frame, and a head hopper is provided at the discharge end. The slewing mechanism is arranged on the support frame and is located below the head hopper. The first belt conveyor is installed on the slewing mechanism, and the first belt conveyor realizes horizontal slewing under the action of the slewing mechanism. One end of the first belt conveyor away from the slewing mechanism is provided with a first discharge cylinder; the second belt conveyor is telescopically arranged on the first belt conveyor, the second belt conveyor is located below the first discharge cylinder, and the discharge end of the second belt conveyor is provided with a second discharge cylinder. By providing a slewing mechanism on the support frame, the slewing mechanism can drive the first belt conveyor to realize the slewing function, so that the coverage range of the materials conveyed on the first belt conveyor is wider. And a telescopic second belt conveyor is arranged on the first belt conveyor. The combination of the first belt conveyor and the second belt conveyor can adjust the length of the material conveying of the belt conveyor, adapt to the material conveying of ships in different situations, and under the telescopic action of the slewing mechanism and the second belt conveyor, the second discharge cylinder on the ship loader can fully cover the cabin in the loading operation area, and the materials can be evenly conveyed into the cabin, avoiding the ship shifting operation during the ship loading operation and also avoiding the problem of ship capsizing caused by untimely ship shifting.

[0004] However, there are still the following problems in this solution. Although the length of the material conveying can be adjusted by the combination of the first belt conveyor and the second belt conveyor, the structure of the belt conveyor is often relatively complex. When the two groups of belt conveyors are used in combination, the occupied space area is relatively large, resulting in a relatively large overall weight of the equipment. And the ship loading process is often suspended conveying, which requires a more complex installation structure to maintain the stability of the belt conveyor during suspended conveying, and the maintenance and use cost of the equipment is relatively high. Summary of the Invention

[0005] The present invention provides a telescopic chute type ship loader, aiming to solve the problems of relatively large occupied space area, relatively large overall weight of the equipment, and relatively high maintenance and use cost in the related art.

[0006] The telescopic inclined chute ship loader of the present invention includes a support beam, on which a support frame is provided. Inside the support frame, a telescopic inclined chute is arranged for transporting materials for ship loading. A tail inclined chute for feeding and a telescopic chute for discharging are arranged on the telescopic inclined chute. A limiting guide rod is fixedly installed inside the support frame, and a stop rod fixed to the support frame is arranged on one side of the limiting guide rod;

[0007] The telescopic inclined chute includes an outer chute pipe and an inner chute pipe. Both the outer chute pipe and the inner chute pipe are inclined. The outer chute pipe is slidably assembled inside the support frame along the length direction of the support frame. The telescopic chute is arranged at one end of the outer chute pipe away from the support frame. A pushing mechanism is arranged on the outer side of the outer chute pipe to push the outer chute pipe to slide inside the support frame. The inner chute pipe is slidably assembled inside the outer chute pipe, and the top end of the inner chute pipe extends outside the outer chute pipe;

[0008] A sliding sleeve is fixedly installed on the outer wall of the outer chute pipe, and the sliding sleeve is slidably assembled on the limiting guide rod. A side plate adapted to the stop rod is fixedly installed on the outer wall of the inner chute pipe, and the side plate is slidably assembled on the limiting guide rod.

[0009] Preferably, the telescopic chute includes a vertical chute, a chute pipe and a cylinder. The vertical chute is inserted into one end of the outer chute pipe away from the support frame. The chute pipe is slidably assembled outside the vertical chute. The cylinder is fixedly installed on the vertical chute, and the telescopic end of the cylinder is fixedly connected to the chute pipe. The effect is that the cylinder can adjust the lifting of the chute pipe outside the vertical chute to adjust the discharging height, so as to better adapt to the change of the material height during ship loading.

[0010] Preferably, a pipe head is fixedly installed at the bottom end of the chute pipe. An inverted conical hopper is fixedly installed inside the pipe head. A closing hopper is rotatably assembled above the conical hopper. Material holes are formed in both the conical hopper and the closing hopper. A second motor is arranged at the bottom of the conical hopper, and the output end of the second motor is fixed to the closing hopper. The effect is that the second motor can drive the closing hopper to rotate, so that the material holes on the closing hopper and the conical hopper are misaligned, so as to adjust the discharging speed of the pipe head and pause the discharging.

[0011] Preferably, the pushing mechanism includes a lead screw, a threaded sleeve and a first motor. The lead screw is rotatably assembled inside the support frame. The threaded sleeve is threadedly connected to the outside of the lead screw, and the threaded sleeve is fixed to the outer chute pipe. The first motor is fixedly assembled on the support frame, and the output end of the first motor is connected to the lead screw through a transmission belt. The effect is that the first motor can drive the lead screw to rotate to push the threaded sleeve to drive the outer chute pipe to move, so as to realize the telescoping of the telescopic inclined chute inside the support frame.

[0012] Preferably, a front support seat and a rear support seat are arranged at the bottom of the support beam. A gantry is arranged at the top of the support beam, and a pull rod is arranged between the gantry and the support beam. A hinge seat is also arranged at the top of the support beam, and the bottom side of the top end of the support frame is hinged inside the hinge seat.

[0013] Preferably, a pitching system and a dust removal system are further provided on the support beam for adjusting the pitching angle of the telescopic chute and removing the material dust raised inside the tail chute.

[0014] Preferably, the pitching system includes a connecting arm, a connecting buckle and a winch. The top end of the connecting arm is rotatably assembled on the gantry, the top end of the connecting buckle is rotatably connected to the bottom end of the connecting arm, the bottom end of the connecting buckle is rotatably assembled on the support frame, and the winch is installed on the support beam. The end of the steel rope in the winch bypasses the gantry and is fixed to the support frame. The effect is that the support frame is suspended on the gantry by the connecting arm and the connecting buckle, and the winch can drive the support frame to rotate on the hinge seat during the winding and unwinding of the steel rope to adjust the pitching angle of the outer chute pipe.

[0015] Preferably, the dust removal system includes a dust suction box and a dust suction pipe. The dust suction box is fixedly installed on the support beam and is located directly above the tail chute. The top end of the dust suction pipe is communicated with the air inlet of the dust suction box. The effect is that the dust suction box can absorb the material dust raised in the tail chute.

[0016] Preferably, the tail chute is inclined, and the bottom end of the tail chute is communicated with the support frame. A hopper located at the port of the tail chute is provided at the top of the inner chute pipe.

[0017] Beneficial effects:

[0018] When the present invention is in use, through the combined use of the sliding sleeve, the side plate and the stop rod, the synchronous telescoping of the inner chute pipe and the outer chute pipe in the support frame and the independent telescoping of the outer chute pipe can better adjust the discharging position during material discharging, improve the ship loading coverage and operation efficiency. While ensuring an increase in the conveying distance, the volume of the equipment is effectively reduced, the weight of the equipment is reduced, and the stability of the equipment during use can be maintained more conveniently, thereby reducing the use cost.

[0027] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0028] As Figures 1 to 6 shown, the telescopic chute type ship loader of the present invention includes a support beam 10. Above the support beam 10, there are a tail chute 20 and a telescopic chute 30 for conveying materials. There is a telescopic chute tube 40 on the telescopic chute 30 to guide the discharge position of the materials. A pitching system 50 and a dust removal system 60 are also provided on the support beam 10. The pitching angle of the telescopic chute 30 can be adjusted by the pitching system 50 to change the discharge position of the telescopic chute tube 40, and the material dust raised inside the tail chute 20 can be removed by the dust removal system 60.

[0029] Refer to Figure 1 and Figure 2 , a front support base 11 and a rear support base 12 are provided at the bottom of the support beam 10, a gantry 13 is provided at the top of the support beam 10, and a tie rod 14 is provided between the gantry 13 and the support beam 10.

[0030] Refer to Figure 2 and Figure 3, a support frame 15 and a hinge seat 16 are provided at the top of the support beam 10. A telescopic inclined chute 30 is arranged inside the support frame 15. The support frame 15 is inclined, and the bottom side of the top end of the support frame 15 is hinged inside the hinge seat 16. A pitching system 50 is arranged between the gantry 13 and the support frame 15, so that the support frame 15 can rotate above the support beam 10 to adjust the pitching of the telescopic inclined chute 30. A limiting guide rod 151 is fixedly installed inside the support frame 15, and a stop rod 152 fixed to the support frame 15 is arranged on one side of the limiting guide rod 151.

[0031] Reference Figure 2 And Figure 3 , the tail inclined chute 20 is inclined, and the bottom end of the tail inclined chute 20 is communicated with the support frame 15, so that materials can enter the telescopic inclined chute 30 inside the support frame 15 along the tail inclined chute 20. A feeding box 21 is arranged at the top end of the tail inclined chute 20 for receiving materials delivered by an external feeding system.

[0032] Reference Figure 2 And Figure 3 , the telescopic inclined chute 30 includes an outer chute pipe 31 and an inner chute pipe 32. Both the outer chute pipe 31 and the inner chute pipe 32 are inclined, and the outer chute pipe 31 is slidably assembled inside the support frame 15 along the length direction of the support frame 15. The inner chute pipe 32 is slidably assembled inside the outer chute pipe 31, and the top end of the inner chute pipe 32 extends outside the outer chute pipe 31.

[0033] Reference Figure 2 、 Figure 3 And Figure 6 , a sliding sleeve 311 is fixedly installed on the outer wall of the outer chute pipe 31, and the sliding sleeve 311 is slidably assembled on the limiting guide rod 151. A side plate 321 adapted to the stop rod 152 is fixedly installed on the outer wall of the inner chute pipe 32, and the side plate 321 is slidably assembled on the limiting guide rod 151. When the outer chute pipe 31 slides into the inside of the support frame 15, the side plate 321 can be pushed by the sliding sleeve 311 to slide along the limiting guide rod 151, so that the inner chute pipe 32 moves synchronously with the outer chute pipe 31 and is retracted into the support frame 15. When the outer chute pipe 31 slides out of the support frame 15, the sliding sleeve 311 retreats relative to the side plate 321. Due to the inclination of the inner chute pipe 32, the inner chute pipe 32 will gradually extend out of the support frame 15 under the action of its own gravity, and the side plate 321 will slide along the limiting guide rod 151. When the side plate 321 is blocked by the stop rod 152 and cannot continue to slide, the inner chute pipe 32 is restricted from extending out of the support frame 15.

[0034] Reference Figure 2 And Figure 3 , a hopper 322 located at the port of the tail inclined chute 20 is arranged at the top of the inner chute pipe 32, so that materials can enter the hopper 322 from the tail inclined chute 20 for ship loading and conveying of the materials.

[0035] ReferenceFigures 2 to 4 On the outside of the outer groove pipe 31, a pushing mechanism 70 is provided for pushing the outer groove pipe 31 to slide within the support frame 15. The pushing mechanism 70 includes a lead screw 71, a threaded sleeve 72, and a first motor 73. The lead screw 71 is rotatably assembled within the support frame 15. The threaded sleeve 72 is threadedly connected to the outside of the lead screw 71 and is fixed to the outer groove pipe 31. The first motor 73 is fixedly assembled on the support frame 15. The output end of the first motor 73 is connected to the lead screw 71 through a transmission belt, and thus can drive the lead screw 71 to rotate, so as to push the threaded sleeve 72 to drive the outer groove pipe 31 to move within the support frame 15, causing the telescopic inclined groove 30 to extend out of the support frame 15.

[0036] Reference Figure 2 And Figure 5 The telescopic chute 40 includes a vertical cylinder 41, a chute pipe 42, and a cylinder 43. The vertical cylinder 41 is inserted into one end of the outer groove pipe 31 away from the support frame 15. The chute pipe 42 is slidably assembled outside the vertical cylinder 41. The cylinder 43 is fixedly installed on the vertical cylinder 41. The telescopic end of the cylinder 43 is fixedly connected to the chute pipe 42. After the material enters the vertical cylinder 41 from the outer groove pipe 31, the chute pipe 42 guides the falling position of the material for ship loading. By driving the chute pipe 42 to lift and lower outside the vertical cylinder 41 through the telescoping of the cylinder 43 and adjusting the height of the chute pipe 42, the discharging height can be better adjusted.

[0037] Reference Figure 5 At the bottom end of the chute pipe 42, a pipe head 421 is fixedly installed. Inside the pipe head 421, an inverted conical hopper 422 is fixedly installed. Above the conical hopper 422, a closing hopper 423 is rotatably assembled. And material holes 424 are formed in both the conical hopper 422 and the closing hopper 423. When the material holes 424 on the conical hopper 422 and the closing hopper 423 are aligned and communicated, the material can be discharged from the pipe head 421, and the material discharge rate increases as the alignment area of the material holes 424 increases. When the material holes 424 on the conical hopper 422 and the closing hopper 423 are completely misaligned, the discharge of the material is paused. A second motor 425 is provided at the bottom of the conical hopper 422, and the output end of the second motor 425 is fixed to the closing hopper 423, so that the second motor 425 can drive the closing hopper 423 to rotate on the conical hopper 422, causing the material holes 424 on the conical hopper 422 and the closing hopper 423 to be aligned or misaligned.

[0038] Reference Figure 2, the pitching system 50 includes a connecting arm 51, a connecting buckle 52, and a winch 53. The top end of the connecting arm 51 is rotatably assembled on the gantry 13. The top end of the connecting buckle 52 is rotatably connected to the bottom end of the connecting arm 51. The bottom end of the connecting buckle 52 is rotatably assembled on the support frame 15. The winch 53 is installed on the support beam 10. The end of the steel rope in the winch 53 bypasses the gantry 13 and is fixed to the support frame 15. By retracting and releasing the steel rope of the winch 53, the connecting arm 51 rotates on the gantry 13, and the outer chute pipe 31 is driven by the connecting buckle 52 to lift and lower. The support frame 15 rotates on the hinge seat 16 to adjust the pitching angle of the outer chute pipe 31.

[0039] Reference Figure 1 And Figure 2 , the dust removal system 60 includes a dust suction box 61 and a dust suction pipe 62. The dust suction box 61 is fixedly installed on the support beam 10 and is located directly above the tail chute 20. The top end of the dust suction pipe 62 is communicated with the air inlet of the dust suction box 61. The bottom end of the dust suction pipe 62 is communicated with the inside of the tail chute 20, so that the dust suction box 61 can absorb the dust shaken up in the tail chute 20 by the dust suction pipe 62 to avoid environmental pollution.

[0040] Working principle: Materials are put into the tail chute 20 from the feeding box 21 and slide down, enter the inner chute pipe 32 through the hopper 322, and then the materials enter the outer chute pipe 31 along the inner chute pipe 32 and are finally discharged and loaded onto the ship by the telescopic chute 40. The dust suction box 61 absorbs the dust shaken up in the tail chute 20 by the dust suction pipe 62;

[0041] By driving the lead screw 71 to rotate through the first motor 73, the threaded sleeve 72 is pushed to gradually slide and extend the outer chute pipe 31 out of the support frame 15. During the extension, the sliding sleeve 311 is driven to slide along the limit guide rod 151 and retreat relative to the side plate 321. As the sliding sleeve 311 retreats, the side plate 321 slides along the limit guide rod 151, causing the inner chute pipe 32 to extend out of the support frame 15 together with the outer chute pipe 31, and the first stage of elongation of the telescopic chute 30 is carried out;

[0042] As the inner chute pipe 32 extends to a certain length, the stop rod 152 will block the side plate 321 sliding along the limit guide rod 151, thereby restricting the inner chute pipe 32 from continuing to extend. Then the first stage of elongation of the telescopic chute 30 is completed. The threaded sleeve 72 continues to move, causing the outer chute pipe 31 to continue to extend, and the second stage of elongation of the telescopic chute 30 is carried out, so that the telescopic chute 40 extends to a farther position for material discharge;

[0043] During material discharge, the steel rope is retracted and released by the winch 53. The connecting arm 51 rotates on the gantry 13, and the outer chute pipe 31 is driven by the connecting buckle 52 to lift and lower, causing the support frame 15 to rotate on the hinge seat 16 to adjust the pitching angle of the outer chute pipe 31.

[0044] In the present invention, through the coordinated use of the sliding sleeve 311, the side plate 321, and the stop rod 152, the synchronous telescoping of the inner trough pipe 32 and the outer trough pipe 31 within the support frame 15 and the independent telescoping of the outer trough pipe 31 can better adjust the discharging position during material discharging, improve the ship loading coverage and operation efficiency. While ensuring an increased conveying distance, it effectively reduces the equipment volume and weight, can more conveniently maintain the stability of equipment use, and then reduces the use cost; through the rotation of the support frame 15 on the support beam 10, the pitching angle of the telescopic chute 30 is adjusted, and in cooperation with the sliding lift of the chute pipe 42 outside the vertical cylinder 41, the discharging height can be adjusted, and then better adapt to the changes in different water levels and the height of the materials on the ship to be loaded, enhancing the universality of the equipment; through the mutual cooperation of the conical hopper 422 and the closed hopper 423, the communication area of the material hole 424 is adjusted to control the discharging speed and better control the ship loading rate.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
