Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project material transportation, and specifically to a material transportation mechanism for water conservancy project construction. Background Art

[0002] Water conservancy project construction refers to the process of transforming the plan of a water conservancy project into an engineering entity by using various processes and technical means according to the design plan. Through construction preparation, technical implementation and management, the construction of water conservancy facilities such as dams, sluices, and pumping stations is completed to meet the requirements of flood control, irrigation, power generation, etc. During the construction of water conservancy projects, waterproof materials, bagged sand and gravel, and precast structural components need to be transported from the unloading point to the construction point. Due to the large quantity, heavy weight and construction requirements of such construction materials, trolleys and transfer vehicles are usually used for transportation and transfer.

[0003] The utility model with the publication number of CN214113883U discloses a raw material transportation device for water conservancy construction. By setting guide rollers, a motor, a connecting plate, a fixing ring and a sheave, an effect of applying a downward inclined force to lighter materials during transportation to make them move forward quickly is achieved, and the problem that in the prior art, in the transportation of raw materials for water conservancy construction, the materials may slip, and the slipping materials will affect the subsequent transportation and the construction progress is solved.

[0004] The invention with the publication number of CN118458229A discloses a feeding device for water conservancy and hydropower construction projects. By setting the cooperation of a movable plate, an arc-shaped frame, an adjusting plate and a transmission frame, while the device starts the L-shaped support rod to drive the conveyor belt assembly to rotate to carry bulk materials, pipes can also be placed on the arc-shaped frame on the movable plate, and driven by the second gear on the L-shaped support rod, the transmission frame on the adjusting plate is driven to carry the pipes at the same time, realizing the transportation of bulk materials and pipes at the same time.

[0005] However, the above-disclosed material transportation mechanism for water conservancy project construction still has the following problems in actual use: Although the annular conveying track is used to transport materials, due to the different types of water conservancy project materials, there are differences in their volume and loading methods. Therefore, some materials are prone to offset above the track and even fall due to the center of gravity problem during transportation. At the same time, the conveying track that is in contact with the materials for a long time continuously rubs during operation and cannot be cleaned in time after the transportation operation, thereby affecting the operation efficiency and service life of the transportation mechanism.

[0006] Therefore, we propose a material transportation mechanism for water conservancy project construction to solve the problems raised above. Summary of the Invention

[0007] The object of the present invention is to provide a conveying mechanism for construction materials in water conservancy projects, aiming to solve the problems that in the existing technology, a ring-shaped conveying track is used to convey materials. However, due to the different types of water conservancy project materials, there are differences in their volumes and loading methods. Therefore, some materials are prone to shift above the track due to the center of gravity problem during the conveying process, and even fall. At the same time, the conveying track that is in long-term contact with the materials continuously rubs during operation and cannot be cleaned in time after the conveying operation, thereby affecting the operation efficiency and service life of the conveying mechanism.

The inner end of the elastic slide rod is slidably arranged in the middle of the lifting guard plate. The inner end of the resisting guard plate is in fitting sliding connection with the inner side of the bearing support.

[0015] Preferably, the bottom end of the lifting guard plate included in the external protection mechanism is connected to the bottom surface of the pressure plate by a main traction steel cable, and the upper outer side of the lifting guard plate is connected to the outer end of the resistance guard plate by an auxiliary traction steel cable, and the middle part of the auxiliary traction steel cable is wound around the top surface of the outer end of the supporting bracket, and the descent of the pressure plate is used to relax the lifting guard plate and then raise it, and the rise of the lifting guard plate is used to slide the resistance guard plate inward.

[0016] Preferably, the dust removal mechanism includes a driving gear, and the driving gear is fixedly mounted on the bottom end of the rotating shaft of the follower dial wheel under the conveying bracket, and the outer side of the driving gear is meshingly connected with a driving rack, and the driving rack is slidably arranged on the outer side of the conveying bracket, and the inner end of the follower dial wheel is in contact with the moving lifting guard plate to realize reciprocating rotation, and the bottom ends of the symmetrically arranged follower dial wheels are connected to each other through a pulley assembly.

[0017] Preferably, the dust removal mechanism includes an air supply and delivery box, and the air supply and delivery box is fixedly installed at the lower right side of the conveying bracket, and a one-way air intake valve is installed through the front and rear ends of the right side of the air supply and delivery box, and a sealing piston plate is slidably installed inside the left side of the air supply and delivery box, and a dust removal spray strip is installed through the top of the air supply and delivery box, and the dust removal spray strip is used to perform jet cleaning on the external defense mechanism moved under the conveying track.

[0018] Preferably, the dust removal mechanism comprises a dust removal spray bar fixedly connected to the right end of the driving rack below the conveying bracket, and the left center position of the dust removal spray bar is fixedly connected to the right end of the pushing slide, and the left end of the pushing slide is slidably connected to the interior of the conveying bracket, and a pushing slider is fixedly installed on the top surface of the left end of the pushing slide.

[0019] Preferably, the dust removal mechanism includes a vibration slide bar slidably installed in the middle part of the bottom surface of the conveying bracket through a return spring, and the bottom end of the vibration slide bar is closely connected to the top surface of the pushing slider, and the top surface of the pushing slider is arranged in an inclined structure with the left side higher and the right side lower, and the reciprocating movement of the pushing slider is used to make the vibration slide bar contact to achieve lifting and lowering, so that the top end of the vibration slide bar collides with the conveying crawler between the left and right dust removal mechanisms to achieve dust and chip removal.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: in the hydraulic engineering construction material conveying mechanism, the hydraulic engineering material is limited and highly protected by the external protection mechanism to avoid rolling due to the center of gravity offset during movement, and at the same time, the reverse external protection mechanism drives the follower dial to rotate intermittently, so as to clean the external protection mechanism and the conveying crawler by jetting and vibration, thereby improving the smoothness of the conveying mechanism operation. The specific contents are as follows:

[0021] 1. The driving motor drives the conveying rotating shaft to rotate, so that the engaged conveying track drives the outer protection mechanisms arranged at equal intervals on the outer wall to move. The material is placed on the pressure plate above the bearing bracket, and then the descending pressure plate relaxes the main traction steel cable during the descending process. When the main traction steel cable no longer limits the lifting guard plate, it drives the contact guard plate on the upper inner side to move upward, so as to rise to an appropriate protection height according to the weight of the material and prevent the material from slipping from the side during movement.

[0022] The rising lifting guard plate drives the contact guard plate to move synchronously, and then the lifting guard plate tensions the auxiliary traction steel cable on the outside, so that the outer end of the auxiliary traction steel cable drives the fixedly connected contact guard plate to slide inward, and then the contact guard plate resists and limits the moving material, thereby improving the stability of the material.

[0023] During the process of the conveying track driving the bearing bracket to move, the conveying track between adjacent bearing brackets can form a limiting area for the material to prevent the material from rolling due to movement. At the same time, the bearing bracket is slidably installed inside the guide chute through the guide slider at the outer end, improving the stability during material conveying and ensuring the smoothness of material conveying.

[0024] 2. The outer protection mechanism that moves under the conveying bracket touches the follower idler wheel through the lifting guard plate. Then, after the follower idler wheel drives the driving gear at the bottom to rotate and engages with the driving rack to move, the driving rack drives the sealing piston plate to slide to the right inside the air supply and conveying box, so as to squeeze the air in the air supply and conveying box to spray upward through the dust removal spray bar at the top, and then jet and dust-remove and clean the corresponding outer protection mechanism.

[0025] 3. The moving sealing piston plate drives the pushing slide plate and the pushing slider to move synchronously. The inclined surface structure at the top of the pushing slider contacts the bottom end of the vibrating slide bar and squeezes the vibrating slide bar to slide upward. Then, the top end of the vibrating slide bar knocks and cleans the conveying track to prevent the residual material from affecting the smooth operation of the conveying mechanism.

[0026] Furthermore, the pushing slide plate drives the pushing slider to move in the reverse direction, so that the pushing slider with the inclined surface structure no longer resists and squeezes the vibrating slide bar. The vibrating slide bar slides downward through the contraction of the return spring, thereby avoiding the moving outer protection mechanism and preventing collision.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1-13 , the present invention provides the following technical solutions:

[0043] Embodiment 1: To solve the problems existing in the transportation of construction materials for existing water conservancy projects, therefore, through the following technical solutions in this embodiment, a conveying mechanism for construction materials of a water conservancy project includes a conveying support 1 and conveying rollers 2 rotatably arranged at the front and rear ends inside the conveying support 1. Moreover, a conveying track 3 is meshed on the outer wall of the conveying rollers 2; the outer protection mechanism includes a bearing support 7, and the bearing supports 7 are fixedly installed on the outer surface of the conveying track 3 at equal intervals. And a pressure plate 8 is elastically slidably installed on the top surface of the bearing support 7. And lifting slide rods 9 are fixedly installed on the front and rear sides of the outer end of the bearing support 7. Moreover, the lifting slide rods 9 slidably penetrate and are connected to the middle of the lifting guard plate 4; the outer protection mechanisms are arranged at equal intervals outside the conveying track 3, and the outer protection mechanism includes a lifting guard plate 4, and a resisting guard plate 5 is slidably arranged above the inside of the lifting guard plate 4.

[0044] The lifting guard plate 4 included in the outer protection mechanism is slidably installed on the front and rear sides of the outer end of the bearing support 7, and the bearing support 7 and the lifting guard plate 4 are connected to each other through a resisting spring 10. And the resisting spring 10 is installed on the outer wall of the lifting slide rod 9. Moreover, the front and rear sides of the outer end of the bearing support 7 are hingedly connected to the upper ends of the guiding sliders 11.

[0045] The outer protection mechanism includes guiding side plates 12, and the guiding side plates 12 are fixedly installed on the front and rear sides inside the conveying support 1. And the guiding side plates 12 are rotatably connected to the conveying rollers 2 through bearings. And a guiding chute 13 is formed inside the guiding side plates 12. At the same time, the guiding chute 13 is slidably connected to one end of the guiding slider 11 away from the bearing support 7. The bottom end of the lifting guard plate 4 included in the outer protection mechanism is connected to the bottom surface of the pressure plate 8 through a main traction steel cable 15. The descent of the pressure plate 8 is used to relax the lifting guard plate 4 and then rise.

[0046] Such as Figures 7-8As shown in the figure, the bearing is installed on the conveying roller 2 inside the guiding side plate 12 and rotates driven by the driving motor on the right side. The conveying track 3 meshed with the conveying roller 2 drives the outer protection mechanism arranged at equal intervals on the top to move. During the conveying process, the material is placed on the top surface of the pressure plate 8 above the bearing bracket 7. Then, the pressure plate 8 is extruded and slides downward, so as to relax the main traction steel cable 15 connected to the outer end, so that the main traction steel cable 15 no longer limits the lifting guard plate 4 fixedly connected to the outer end. After the contact spring 10 sleeved on the outer wall of the lifting slide rod 9 extends, it drives the lifting guard plate 4 to move upward along the outer end of the bearing bracket 7, so as to protect the side of the conveyed material. Moreover, the greater the weight of the material, the higher the relative protection height of the lifting guard plate 4, so as to improve the stability of conveying.

[0047] The outer end of the contact guard plate 5 included in the outer protection mechanism slides through the upper part inside the lifting guard plate 4, and the outer end of the elastic slide rod 14 is slidably penetrated through the outer end of the contact guard plate 5. Moreover, the inner end of the elastic slide rod 14 is slidably arranged in the middle of the lifting guard plate 4, and the inner end of the contact guard plate 5 is in sliding contact connection with the inner side of the bearing bracket 7; and the outer side above the lifting guard plate 4 and the outer end of the contact guard plate 5 are connected to each other by the secondary traction steel cable 16, and the middle part of the secondary traction steel cable 16 is wound around the top surface of the outer end of the bearing bracket 7. At the same time, the upward movement of the lifting guard plate 4 is used to slide the contact guard plate 5 inward.

[0048] As Figures 4-6 As shown in the figure, the upward movement of the lifting guard plate 4 drives the secondary traction steel cable 16 connected to the outside to be tensioned. After the outer end of the secondary traction steel cable 16 is tensioned, it drives the fixedly connected contact guard plate 5 to slide inward along the direction of the elastic slide rod 14, so as to contact the material during the conveying process through the contact guard plate 5, and assist the stability of the material during the conveying process. At the same time, the bearing bracket 7 is slidably arranged in the guiding chute 13 inside the guiding side plate 12 through the guiding slider 11 at the outer end, so as to avoid detachment due to force during movement. Moreover, the bearing brackets 7 arranged at equal intervals can cooperate with the conveying track 3 to form a blocking area, so as to avoid the material from rolling during the conveying process.

[0049] Embodiment 2: To solve the problems existing in the transportation of construction materials for existing water conservancy projects, the following technical solutions are adopted in this embodiment. A dust removal mechanism is provided below the conveying support 1, and the dust removal mechanism includes follower pulleys 6 rotatably arranged on the front and rear sides below the conveying support 1 through torsion springs, and the follower pulleys 6 are rotated by contacting the outer protection mechanism; the dust removal mechanism includes a driving gear 17, and the driving gear 17 is fixedly installed at the bottom end of the rotating shaft of the follower pulley 6 below the conveying support 1, and a driving rack 18 is meshed and connected to the outside of the driving gear 17, and the driving rack 18 is slidably arranged on the outside of the conveying support 1, and the inner end of the follower pulley 6 rotates reciprocally after fitting and moving on the lifting guard plate 4, and at the same time, the bottom ends of the symmetrically arranged follower pulleys 6 are connected to each other through a pulley assembly 27.

[0050] The dust removal mechanism includes a gas supply and conveying box 19, and the gas supply and conveying box 19 is fixedly installed below the right side of the conveying support 1, and one-way intake valves 20 are installed through the front and rear ends on the right side of the gas supply and conveying box 19, and a sealing piston plate 21 is slidably installed inside the left side of the gas supply and conveying box 19, and at the same time, a dust removal spray bar 22 is provided through the top of the gas supply and conveying box 19, and the outer protection mechanism moving below the conveying track 3 is jet-cleaned through the dust removal spray bar 22; the dust removal spray bar 22 included in the dust removal mechanism is fixedly connected to the right end of the driving rack 18 below the conveying support 1.

[0051] As Figures 9-11 shown, when the conveying track 3 drives the outer protection mechanism and the material to move to the end, the material is separated from the outer protection mechanism by its own weight, and then the outer protection mechanism follows the conveying track 3 to move below the conveying support 1. At the same time, the outer protection mechanism contacts the follower pulleys 6 on the front and rear sides through the lifting guard plate 4, and drives the follower pulleys 6 and the driving gear 17 at the bottom end to rotate. Then, the engaged driving rack 18 drives the fixedly connected sealing piston plate 21 to slide to the right, so as to squeeze the air inside the gas supply and conveying box 19 through the sealing piston plate 21, so that the gas supply and conveying box 19 sprays the internal air upward through the dust removal spray bar 22 at the top, so as to perform jet dust removal cleaning on the outer protection mechanism in an inverted state.

[0052] Furthermore, the moving sealing piston plate 21 drives the pushing slide plate 23 and the pushing slider 24 to move synchronously. The pushing slider 24 with an inclined surface structure rises after squeezing the vibration slide bar 26 through the bottom surface, so that the vibration slide bar 26 collides with the bottom surface of the conveying track 3 through the top end, assisting in cleaning the material residue adhered to the outer wall of the conveying track 3, improving the smoothness of the operation of the conveying mechanism and reducing energy consumption.

[0053] The left center position of the dust removal spray bar 22 is fixedly connected to the right end of the pushing slide plate 23, and the left end of the pushing slide plate 23 is slidably connected to the inside of the conveying support 1. Moreover, a pushing slider 24 is fixedly installed on the top surface of the left end of the pushing slide plate 23. The dust removal mechanism includes a vibrating slide rod 26 slidably installed in the middle of the bottom surface of the conveying support 1 through a return spring 25. The bottom end of the vibrating slide rod 26 is in contact with the top surface of the pushing slider 24. The top surface of the pushing slider 24 is arranged in an inclined plane structure that is higher on the left and lower on the right. The reciprocating movement of the pushing slider 24 is used to push against the vibrating slide rod 26 to achieve lifting and lowering, so that the top end of the vibrating slide rod 26 collides with the conveying track 3 between the left and right dust removal mechanisms to remove dust and chips.

[0054] As Figures 11-13 shown, the lifting guard plate 4 and the follower pulley 6 in the misaligned state are disengaged from each other. Then, the follower pulley 6 connected by the torsion spring drives the driving gear 17 to rotate in the reverse direction for resetting. The engaged driving rack 18 drives the sealing piston plate 21 to slide to the left. After the sealing piston plate 21 drives the pushing slide plate 23 and the pushing slider 24 to move to the left, it no longer pushes against the bottom end of the vibrating slide rod 26. So that the vibrating slide rod 26 descends by the compression of the return spring 25 to avoid collision with the outer protection mechanism, and then the outer protection mechanism and the conveying track 3 are cleaned and dusted.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
