Description

Technical Field

[0001] The invention relates to the technical field of loading and unloading tools, in particular to a belt installation tool for a self-unloading device which is convenient for loading and unloading. Background Art

[0002] The marine conveyor belt is over 600 meters long and 22mm thick. It is supplied in rolls, making it difficult to pull manually. Using a sling is also difficult due to its rigid connection, and this process takes a long time and is inefficient.

[0003] Therefore, the traditional marine conveyor belt installation has the following defects:

[0004] 1. Since marine conveyor belts are relatively heavy, they are not easy to load, unload, transport and install, and manual loading and unloading and installation are very labor-intensive.

[0005] 2. During transportation with existing slings, the conveyor belt cannot rotate flexibly due to the rigid connection, making it inconvenient to install the conveyor belt;

[0006] 3. The installation period of the conveyor belt is long and the working efficiency is low. Summary of the Invention

[0007] The purpose of the present invention is to solve the above technical problems and provide a tool that is convenient for loading, unloading and transporting conveyor belts. It can provide a belt installation tool for a self-unloading device that has automatic loading and unloading, can be flexibly moved, and can transport belts.

[0008] To achieve the above-mentioned object, the present invention adopts the following technical solution: a belt installation tool for a dump device, comprising a flatbed truck, a turntable provided on the flatbed truck, a first drive motor provided at the bottom of the flatbed truck, and an output shaft of the first drive motor connected to the turntable;

[0009] The turntable is provided with a supporting plate, the supporting plate is provided with a pair of vertical frames, each of the vertical frames is provided with a vertically movable slide, and each of the vertical frames is provided with a driving device on the outer side to drive the slide to move vertically;

[0010] Each of the slides is provided with a guide rail, the two guide rails are arranged in parallel, a walking beam is provided across the two guide rails, a second drive motor is provided on the outer side of the walking beam, the second drive motor drives the walking beam to move along the guide rail, a pair of forks parallel to the guide rails are provided on one side of the walking beam, and each fork is provided with a first groove;

[0011] A pair of support frames are provided on the support plate between the pair of forks, and each of the support frames is provided with a second groove. For the same object, the support surface of the second groove is higher than the support surface of the first groove.

[0012] This invention can realize walking and rotation through the flatbed truck and the turntable, and can drive the guide rail and the walking beam to be lifted through the driving device. The walking beam can walk on the guide rail, drive the fork to load and unload the conveyor belt, and then place the conveyor belt on the support frame through the lowering of the driving device, thereby realizing the loading and unloading transportation of the conveyor belt.

[0013] In order to make the conveyor belt easy to rotate, a further preferred technical solution is that a pair of symmetrically arranged support wheels are provided in each of the second grooves.

[0014] In order to facilitate the installation of the conveyor belt, a further preferred technical solution is that a pair of guide wheels are provided on the other side of the walking beam, and a pair of drive rollers are also provided on the walking beam between the guide wheels and the fork. A third drive motor is provided on the outside of the walking beam, and the third drive motor drives one of the drive rollers to rotate. The belt is driven by the drive roller, and there is no need for manual pulling of the belt for installation.

[0015] In order to adapt to the changes in the installation angle during the belt installation process, a further preferred technical solution is that a pair of guide wheels are symmetrically arranged on a plane between a pair of driving rollers, each guide wheel is installed on a wheel frame, and the wheel frame has a rotating shaft, and the rotating shaft is installed in the bearing seat through a bearing, and the bearing seat is slidably installed in the guide hole of the mounting seat, and the mounting seat is fixed on the walking beam, and a bearing cover is threadedly connected to one end of the guide hole close to the guide wheel, and a pressure sensor is installed at the other end of the guide hole, and a spring is provided in the guide hole between the pressure sensor and the bearing seat. When the installation angle changes, the guide wheel is subjected to a change in force, and the information feedback from the pressure sensors on both sides is compared in the controller, and then the first drive motor is controlled to drive the turntable to rotate to adapt to the change in the installation angle. When the forces at both ends of the guide wheel are balanced, the first drive motor automatically stops working.

[0016] In order to make the driving device simple in structure and easy to use, a further preferred technical solution is that the driving device includes a jack, the jack is connected to an electric pump installed on the stand, and the electric pump drives the piston rod of the jack to rise and fall.

[0017] In order to ensure smooth contact between the guide wheel and both sides of the belt and facilitate guiding, a further preferred technical solution is that the guide wheel has an arc-shaped groove on its outer circumference.

[0018] In order to provide a stable support, a further preferred technical solution is that both the first groove and the second groove are V-shaped grooves.

[0019] In order to keep the device stable and prevent tilting during loading and unloading, a further preferred technical solution is that the flatbed truck and the supporting flat plate have an identical opening on one side of the corresponding fork, and the opening can accommodate the conveyor belt, so that the fork can avoid excessive center deviation during loading and unloading, thereby keeping the device balanced.

[0020] In order to prevent the device from tipping over, a further preferred technical solution is that a counterweight block for balancing is provided on the supporting plate.

[0022] 2. The guide rail and the walking beam are driven by the driving device to lift. The walking beam can travel on the guide rail to drive the fork to load and unload the conveyor belt. Then, the conveyor belt is placed on the support frame by lowering the driving device to realize the loading and unloading transportation of the conveyor belt.

[0023] 3. The belt is driven by a driving roller, eliminating the need for manual belt pulling and installation.

[0024] 4. Through the cooperation of the guide wheel and the pressure sensor, the belt can automatically rotate during installation to adapt to changes in the installation angle. Moreover, the elastically assembled guide wheel has a rotating and elastically deformable structure, and the guiding effect is more significant. BRIEF DESCRIPTION OF THE DRAWINGS

A first drive motor 2 is provided at the bottom of the flatbed truck 1, and the output shaft of the first drive motor 2 is connected to the input end of the reducer. The output end of the reducer is connected to the turntable 20 through a through hole in the bottom of the flatbed truck. The output end can be connected to the turntable 20 through a key and a key sleeve, or a spline sleeve can be provided under the turntable 20, and the output end is directly connected to the spline shaft;

[0035] The turntable 20 is provided with a supporting plate 3, and a pair of vertical frames 5 are provided on the supporting plate 3. The vertical frames 5 are provided with a U-shaped guide groove, and a vertically movable slide 19 is provided in the guide groove of each of the vertical frames 5. A driving device 4 is provided on the outer side of each of the vertical frames 5 to drive the slide 19 to move vertically;

[0036] In order to simplify the structure of the driving device 4 and facilitate its use, the driving device 4 further includes a jack, which is connected to an electric pump mounted on a stand. The electric pump drives the piston rod of the jack to move up and down, and the piston rod is fixedly connected to the slide 19 via a connecting plate. The corresponding side of the stand 5 has a through slot for the connecting plate to pass through and be fixedly connected to the slide 19.

[0037] Alternatively, the driving device 4 may be composed of a hydraulic cylinder and a hydraulic system installed at the bottom of the flatbed vehicle 1;

[0038] like Figure 3 and Figure 4As shown, each of the slides 19 is provided with a guide rail 6, and the two guide rails 6 are arranged in parallel. An inverted T-shaped through-slot 6a is provided on the guide rails 6 along the length thereof, and a cross-walking beam 7 is provided on the two guide rails 6. A pair of rollers 21 are provided on the walking beam 7 corresponding to the bottom of each guide rail 6. The rollers 21 are restricted in the T-shaped through-slot 6a and can rotate and reciprocate along the guide rails 6. A second drive motor 17 is provided on the outer side of the walking beam 7, and the second drive motor 17 is connected to the roller 21 on the adjacent side through a transmission chain. The second drive motor 17 drives the walking beam 7 to move along the guide rails 6. A pair of forks 8 parallel to the guide rails are provided on one side of the walking beam 7, and each fork 8 is provided with a first groove 8a. The fork 8 can be fixed on the walking beam 7 or can be sleeved on the walking beam 7 to adjust the distance between the two forks 8;

[0039] A pair of support frames 9 are provided on the support plate 3 between the pair of forks 8, each of the support frames 9 is provided with a second groove 9a, and for the same object, the support surface of the second groove 9a is higher than the support surface of the first groove 8a;

[0040] In this embodiment, the flatbed truck 1 and the turntable 20 can be used to move and rotate, and the guide rail 6 and the walking beam 7 can be driven to rise by the driving device 4. The walking beam 7 can move on the guide rail 6 to drive the fork 8 to load and unload the conveyor belt, and then the conveyor belt can be placed on the support frame 9 by lowering the driving device 4 to realize the loading and unloading transportation of the conveyor belt.

[0041] Furthermore, in order to make the conveyor belt easy to rotate, each second groove 9a is provided with a pair of symmetrically arranged support wheels 10, and a vertical open groove is provided in the second groove 9a. The support wheel 10 is installed in the open groove through a wheel axle and a bearing, and the contact surface of the support wheel 10 with the object is higher than the contact surface of the second groove 9a with the object.

[0042] Furthermore, in order to facilitate the installation of the conveyor belt, a pair of guide wheels 16 are provided on the other side of the walking beam 7. A pair of drive rollers 11 are also provided on the walking beam 7 between the guide wheel 16 and the fork 8. The pair of drive rollers 11 are arranged in parallel on the walking beam 7. Both ends of the drive rollers 11 are installed on the walking beam 7 through bearings. A third drive motor 18 is provided on the outside of the walking beam 7. The third drive motor 18 drives one of the drive rollers 11 to rotate, and the belt is driven by the drive roller 11, eliminating the need for manual belt pulling installation.

[0043] like Figure 5As shown, further, in order to adapt to the change of the installation angle during the belt installation process, a pair of guide wheels 16 are symmetrically arranged on the plane between the pair of driving rollers 11, and each guide wheel 16 is installed on the wheel frame 15. The wheel frame 15 has a rotating shaft 15a, and the rotating shaft 15a is fixedly installed in the bearing seat 23 through a bearing. The bearing seat 23 is slidably installed in the guide hole 12a of the mounting seat 12, and the mounting seat 12 is fixed on the walking beam 7. The bearing cover 14 is threadedly connected to one end of the guide hole 12a near the guide wheel 16, and the pressure sensor 13 is threadedly installed on the other end of the guide hole 12a. The pressure sensor 13 is connected to the A spring 22 is provided in the guide hole 12a between the bearing seats 23, so that the guide wheel 16 can rotate around the rotating shaft 15a. Because the bearing seat 23 is in sliding fit with the guide hole 12a, it can be elastically compressed. When the installation angle changes, the force on the guide wheel 16 changes. The signals fed back by the pressure sensors 13 on both sides are compared in the controller, and then the first drive motor 2 is controlled to drive the turntable 20 to rotate to adapt to the change in the installation angle. When the forces at both ends of the guide wheel 16 are balanced, the first drive motor 2 automatically stops working. At the same time, the guide wheel 16 can freely rotate around the rotating shaft 15a of the wheel frame 15 to adapt to the guidance.

[0044] Furthermore, in order to ensure smooth contact between the guide wheel 16 and both sides of the belt and facilitate guidance, the guide wheel 16 has an arc-shaped groove 16a on its outer circumference;

[0045] Furthermore, in order to provide a stable support, both the first groove 8a and the second groove 9a are V-shaped grooves;

[0046] like Figure 6 As shown, further, the flatbed truck 1 and the supporting plate 3 have a same opening on one side corresponding to the fork 8, and the opening can accommodate the conveyor belt, so that the fork 8 can avoid excessive center deviation during loading and unloading, thereby maintaining the balance of the device;

[0047] Furthermore, in order to prevent the device from tipping over, a counterweight block for balancing is provided on the supporting plate 3 .

[0048] The working principle of this device is as follows: the flatbed car 1 moves to the conveyor belt placement position. If possible, the conveyor belt should be placed in the opening, and the guide rail 6 and the walking beam 7 are lifted by the driving device 4. The walking beam 7 moves. When the walking beam 7 crosses the support frame 9, in order to prevent interference, the upper end of the support frame 9 is narrowed, and the driving device 4 falls back. The entire roll of conveyor belt is inserted into the core shaft, and the fork 8 is moved to the bottom of the core shaft. The driving device 4 is lifted again to lift the conveyor belt, and the walking beam 7 returns to cross the support frame 9 again. When the fork 8 moves to the top of the support frame 9, the driving device 4 then falls back again to place the conveyor belt on the support frame 9, move the conveyor belt to the installation position, and introduce the conveyor belt end into a pair of the driving devices. The guide rollers 11 are inserted between the guide rollers 11, and then introduced between a pair of guide wheels 16. Before or after the conveyor belt end is introduced, the walking beam 7 can be driven by the second drive motor 17 to adjust the position of the drive roller 11 on the guide rail 6. After adjusting the position, the third drive motor 18 is started to transport the conveyor belt. At this time, the worker can install the belt to the specified position. When the angle changes during the installation process, the force on the guide wheel 16 changes, and the information fed back by the pressure sensors 13 on both sides is compared in the controller. Then the first drive motor 2 is controlled to drive the turntable 20 to rotate to adapt to the change in the installation angle. When the forces at both ends of the guide wheel 16 are balanced, the first drive motor 2 automatically stops working. At the same time, the guide wheel 16 can rotate freely around the rotating shaft 15a of the wheel frame 15 to adapt to the guidance.
