Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a cleaning device for belt conveyors. Background Art

[0002] Belt conveyor is a continuous transport machine driven by friction, which is used to transport materials from the feeding point to the unloading point. Because its design structure can be flexible and changeable according to the on-site conditions to adapt to different working environments and transportation requirements, and it has the advantages of good stability and low cost, it has been widely used in thermal power plants and coal mines. However, due to factors such as coal washing and the use of spray dust reduction devices in coal washing plants, the coal contains a large amount of water, so that some of the coal adheres to the surface of the conveyor belt during long-distance transportation with the conveyor belt. At present, the conveyor belt is usually cleaned by scraping off the coal attached to the surface of the conveyor belt by setting a scraper at the bottom of the conveyor belt. However, it is difficult to control the force of the contact between the scraper and the surface of the conveyor belt. When the scraper is too tight against the surface of the conveyor belt, it is easy to damage the conveyor belt and cause the conveyor belt to deform; when the scraper is too loose against the surface of the conveyor belt, it is difficult to scrape off the coal attached to the surface of the conveyor belt, and the cleaning effect of the conveyor belt is poor.

The transmission structure includes a mounting seat, a movable block and a plurality of lifting rods arranged at intervals along the longitudinal direction. The mounting seat is arranged on the base, and the movable block can be movably arranged on the mounting seat along the longitudinal direction. The upper end of each of the lifting rods is hinged to the bottom of the lifting seat, the lower end of at least one of the lifting rods is hinged to the movable block, and the lower ends of the remaining lifting rods are hinged to the mounting seat.

[0028] The utility model provides a cleaning device 100 for a belt conveyor.

[0029] See also Figures 1 to 3 In one embodiment of the utility model, the conveyor belt of the belt conveyor is arranged above the cleaning device 100, and the cleaning device 100 includes a base 10, a cleaning mechanism 20 and a lifting seat 30; wherein the cleaning mechanism 20 includes a cleaning assembly 21, and the cleaning assembly 21 includes a supporting structure 22, a cleaning rod 23, a scraper 24 and an elastic telescopic member 25, and the two ends of the cleaning rod 23 along its extension direction are respectively a cleaning end 231 and a connecting end 232, and the scraper 24 is installed at the cleaning end 231, and a hinge position 23 is formed on the cleaning rod 23 between the cleaning end 231 and the connecting end 232. 3. The hinged position 233 is hinged to the support structure 22, so that the cleaning rod 23 rotates relative to the support structure 22 to make the cleaning end 231 rise and fall. The support structure 22 is provided with an angle sensor for detecting the rotation angle of the cleaning rod 23; the two ends of the elastic telescopic member 25 are respectively connected to the support structure 22 and the connection end 232; the support structure 22 is installed on the lifting seat 30, and the lifting seat 30 is arranged on the base 10 and can drive the lifting seat 30 to rise or fall relative to the base 10 through the lifting mechanism 40, and drive the cleaning mechanism 20 to rise or fall, so as to correspondingly make the scraper 24 close to or loosen the conveyor belt.

[0030] Horizontal Figure 1 The left and right directions in the vertical direction are Figure 1 The front-to-back direction in the Figure 1The up and down directions in .

[0031] The technical solution of the utility model is to set the cleaning device 100 of the belt conveyor of the utility model under the conveyor belt of the belt conveyor. The cleaning device 100 of the belt conveyor of the utility model includes a base 10, a cleaning mechanism 20 and a lifting seat 30. The lifting seat 30 can be driven to rise and fall by the lifting mechanism 40, thereby driving the cleaning assembly 21 on the lifting seat 30 to rise and fall, so that the scraper 24 on the cleaning assembly 21 can rise to abut against the bottom of the conveyor belt. When the conveyor belt is transported, the coal material on the surface of the conveyor belt can be scraped off by the scraper 24 to achieve cleaning of the conveyor belt. The scraper 24 is installed on the cleaning end 231 of the cleaning rod 23, and the hinge position 233 of the cleaning rod 23 is hinged to the support structure 22 on the lifting seat 30, and the connection end 232 of the cleaning rod 23 is connected with an elastic telescopic member 25, and the elastic telescopic member 25 can adopt a spring in the prior art.

[0032] Furthermore, after the lifting seat 30 drives the scraper 24 to rise to abut against the bottom of the conveyor belt, when the lifting seat 30 continues to be driven to rise, the scraper 24 cannot continue to rise because it has abutted against the bottom of the conveyor belt, and because the scraper 24 is installed on the hinged end 2221, the hinged end 2221 can be raised and lowered relative to the support structure 22. Therefore, the cleaning end 231 and the scraper 24 are lowered relative to the support structure 22 and the lifting seat 30, and the connecting end 232 of the cleaning rod 23 is driven to move in the opposite direction and rise relative to the support structure 22 and the lifting seat 30, thereby stretching the elastic telescopic member 25, and the restoring force of the elastic telescopic member 25 acts on the connecting end 232 and is transmitted to the cleaning end 231, so that the scraper 24 can be pressed against the bottom of the conveyor belt. By driving the lifting seat 30 to rise and fall, the bottom of the conveyor belt can be abutted or loosened, and an angle sensor is arranged on the support structure 22. The rotation angle of the cleaning rod 23 is obtained by the angle sensor to obtain the height of the connection end 232, thereby obtaining the stretching length of the elastic telescopic member 25, and finally the force of the scraper 24 abutting against the bottom of the conveyor belt can be obtained by calculation. Before the conveyor belt needs to be cleaned, the angle threshold of the rotation angle of the cleaning rod 23 is set. When the lifting seat 30 is driven to rise and fall, the degree of the angle sensor is read, and the lifting seat 30 is driven to rise and fall according to the degree of the angle sensor. When the degree of the angle sensor is within the angle threshold, the force of the scraper 24 abutting against the bottom of the conveyor belt can be adaptively made to be in a suitable range, avoiding the scraper 24 from abutting too tightly against the surface of the conveyor belt to damage the conveyor belt, and reducing the degree of deformation of the conveyor belt; at the same time, it is also avoided that the scraper 24 is too loosely abutted against the surface of the conveyor belt to scrape off the coal attached to the surface of the conveyor belt, and the cleaning effect of the conveyor belt is better.

[0033] It can be understood that the controller can obtain the rotation angle of the cleaning rod 23 detected by the angle sensor, and the controller analyzes and determines whether the rotation angle of the cleaning rod 23 is within the angle threshold. If the rotation angle is within the angle threshold, the controller does not need to control the lifting mechanism 40 to drive the lifting seat 30 to rise or fall relative to the base 10; if the rotation angle is not within the angle threshold, the controller controls the lifting mechanism 40 to drive the lifting seat 30 to rise or fall relative to the base 10, so as to adaptively adjust the force of the scraper 24 abutting against the bottom of the conveyor belt, which is more intelligent.

[0034] In one embodiment of the utility model, the support structure 22 includes a support seat 221 and a movable plate 222.

[0035] Specifically, Figure 1 and Figure 3 As shown, the first hinge shaft 223 and the second hinge seat are both extended in the left-right direction, the cleaning rod 23 can be rotatably hinged to the support seat 221 around the first hinge shaft 223, the movable plate 222 can be rotatably hinged to the support seat 221 around the second hinge shaft 224, and the two ends of the elastic telescopic member 25 are respectively connected to the movable plate 222 and the connecting end 232. A pushing member is provided on the support seat 221, and the pushing member can push the movable plate 222 in the up-down direction. By pushing the movable plate 222, the elastic telescopic member 25 can be stretched or shortened, thereby further adjusting the contact force between the scraper 24 and the bottom of the conveyor belt, and the adjustability is higher.

[0036] In one embodiment of the utility model, the push member is a bolt 225 , a screw hole 226 is opened on the support seat 221 , the bolt 225 is vertically penetrated into the screw hole 226 and threadedly engaged with the screw hole 226 , and the bottom end of the bolt 225 abuts against the top of the movable plate 222 .

[0037] Specifically, Figure 3 As shown, the height of the bottom end of the bolt 225 can be adjusted by the threaded fit of the bolt 225 and the screw hole 226, thereby achieving the stretching or shortening of the elastic telescopic member 25, which is simple and convenient. At the same time, the bolt 225 and the nut also have a self-locking function, which can effectively prevent the bottom end height of the bolt 225 from changing when the bottom end height of the bolt 225 is not adjusted, and the reliability is higher.

[0038] In one embodiment of the utility model, the two ends of the movable plate 222 along its extension direction are respectively a hinged end 2221 and a free end 2222, the hinged end 2221 is hinged to the bottom of the support seat 221 through a second hinge shaft 224, the pushing member is arranged close to the free end 2222, and the two ends of the elastic telescopic member 25 are respectively connected to the hinged end 2221 and the connecting end 232.

The free end 2222 is far away from the hinged end 2221, and the pushing member is arranged near the free end 2222. When the pushing member pushes the movable plate 222, the force arm of the pushing force exerted by the pushing member on the movable plate 222 is large, and the pushing of the movable plate 222 is easier.

[0040] In an embodiment of the utility model, the scraper 24 is detachably mounted with a counterweight 26 ; and / or a damper 27 is connected between the scraper 24 and the cleaning rod 23 .

[0041] Specifically, Figure 3 As shown, a counterweight 26 is detachably mounted on the scraper 24, so that when the blade head does not abut the bottom of the conveyor belt, the cleaning rod 23 can be prevented from rising too high due to the restoring force of the spring, and the structure is more reasonable. A damper 27 is arranged between the scraper 24 and the cleaning rod 23, and the damper 27 can effectively absorb the vibration and impact of the conveyor belt on the scraper 24 during transportation. The scraper 24 can be effectively protected from damage caused by excessive vibration, and the scraper 24 can be prevented from damaging the conveyor belt, and the durability is good.

[0042] In an embodiment of the present invention, the cleaning mechanism 20 includes a plurality of cleaning components 21 , and the plurality of cleaning components 21 are disposed on the lifting base 30 at intervals along the lateral direction.

[0045] Specifically, Figure 1 and Figure 2 As shown, the movable block 4122 is driven to move in the front-to-back direction by the driving structure 411, and the movable block 4122 drives the lower end of the lifting rod 4123 hinged thereto to move in the front-to-back direction, so as to drive the lower end of the lifting rod 4123 to rotate relatively around the upper end of the lifting rod 4123, thereby driving the upper end of the lifting rod 4123 and the lifting seat 30 connected to the upper end of the lifting rod 4123 to rise and fall, which is simple and convenient. The upper and lower ends of the remaining lifting rods 4123 are respectively connected to the lifting seat 30 and the mounting seat 4121 at intervals along the front-to-back direction. When the lifting seat 30 is raised or lowered, the upper ends of the remaining lifting rods 4123 are passively raised or lowered with the lifting seat 30, and passively rotated around the lower end of the corresponding lifting rod 4123. By using a plurality of lifting rods 4123 arranged at intervals along the front-to-back direction, the lifting seat 30 can be more stably installed on the base 10 and raised or lowered, and the structural reliability is higher.

A screw rod 4111 nut seat is provided outside the screw rod 4111, and the screw rod 4111 nut seat is matched with the screw rod 4111 thread. When the screw rod 4111 is driven to rotate by the rotating driving member 4112, the screw rod 4111 nut seat moves in the front-to-back direction relative to the screw rod 4111, thereby driving the movable block 4122 to move in the front-to-back direction.

At the same time, since the lower end of the lifting rod 4123 is driven to rotate relatively around the upper end of the lifting rod 4123, the upper end of the lifting rod 4123 and the lifting seat 30 connected to the upper end of the lifting rod 4123 are driven to move in the front-to-back direction during the lifting and lowering process. Therefore, the guide rod 11 is arranged on the base 10 so as to be movable in the front-to-back direction, so that the guide rod 11 and the lifting seat 30 do not conflict with each other, and the structure is reasonable.
