Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant floor construction, in particular to a diamond sand spreading device for wear-resistant floor. Background Art

[0002] Emery flooring has been widely used in many places such as industrial plants, warehouses, parking lots, etc. due to its advantages of high strength, wear resistance and corrosion resistance. Emery spreading is a key link in the construction process of emery flooring, and its spreading effect directly affects the quality and performance of the floor.

[0003] Traditional corundum spreading equipment mainly puts corundum materials into the hopper and controls the hopper to discharge materials through a mobile vehicle to achieve the spreading effect. This traditional spreading method has many limitations. First, the discharge volume of the discharge port of traditional equipment is usually fixed. In actual construction, different floor areas often have different requirements for the thickness of corundum. For example, in industrial plants, areas where heavy equipment is placed require a thicker corundum layer to withstand greater pressure and wear, while areas such as personnel passages only require a relatively thin corundum layer. Since traditional equipment cannot flexibly adjust the discharge volume according to different thickness requirements, it is easy to cause excessive discharge of corundum and waste of materials when laying thin corundum layers; and when laying thick corundum layers, the design thickness requirements may not be met due to insufficient discharge, which in turn affects the overall quality and service life of the floor.

[0004] Secondly, it is difficult for traditional spreading equipment to ensure the flatness and uniformity of the diamond sand. Due to the fixed output, the distribution of diamond sand cannot be accurately controlled according to the actual situation during the spreading process, which easily leads to diamond sand accumulation or vacancies, making the floor surface uneven, which not only affects the aesthetics of the floor, but also causes local wear and uneven force in the subsequent use process, reducing the reliability and durability of the floor.

[0015] Compared with the related art, the diamond sand spreading equipment for wear-resistant floor provided by the present invention has the following beneficial effects: The present invention provides a corundum spreading device for wear-resistant floor. In the present invention, the spreading thickness of corundum and the falling amount of corundum are both adjustable, and the adjustment process of the spreading thickness of corundum is synchronously performed with the adjustment of the falling amount of corundum, that is, the falling amount of corundum increases with the increase of the corundum thickness, thereby avoiding the waste of corundum material.

[0016] The present invention provides a diamond abrasive spreading device for wear-resistant floor. When the present invention performs a spreading operation, a driving roller rotates together with a driving wheel group, and the driving roller rotates synchronously with a driving shaft. The rotation of the driving roller drives an extrusion channel on its surface to rotate and squeeze an extrusion rod, so that the extrusion rod is subjected to an extrusion force from an inner wall of the extrusion channel. Since the position of the driving rod is locked by a rectangular rod, the direction of the extrusion force can be understood as being parallel to the direction of the driving roller axis, that is, the extrusion rod performs a reciprocating motion in the direction of the driving roller axis while sliding along the extrusion channel. When the extrusion rod reciprocates, the driving rod, the round rod and the placing frame are synchronously driven to reciprocate. The placing frame drives a plurality of anti-blocking rods to reciprocate the diamond abrasive in a spreading hole, so that the diamond abrasive in this area is subjected to an axial thrust, thereby avoiding the situation that the diamond abrasive is blocked during the spreading process, and the spreading process is smoother.

[0017] The present invention provides a diamond abrasive spreading device for wear-resistant floor. The present invention is combined into a spreading chamber through multiple components. The outer sides of two baffles of the spreading chamber are cooperated with fixed pulleys. The horizontal height of the lowest point of the positioning wheel is less than the horizontal height of the lower end surface of the baffle. In this state, the positioning wheel adaptively contacts with the construction ground and adapts to different construction grounds. At the same time, the spreading chamber can suppress the dust generated during spreading inside it, effectively preventing the dust from directly drifting into the surrounding environment.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0021] See also Figure 1-Figure 8 The present invention discloses a diamond abrasive spreading device for wear-resistant floor, comprising a mobile frame 1 and a spreading hopper 2. The mobile frame 1 is made of steel structure and is equipped with a driving wheel set. The mobile frame 1 is equipped with a handle frame 12, and the mobile frame 1 can be driven to move by the handle frame 12. The driving wheel set is generally a common type with a turning system on the market. In this embodiment, manual pushing is used as an example for explanation. In actual use, the driving wheel set can also be mechanically driven or electrically driven. The material spreading hopper 2 is located in the center of the mobile frame 1, and the material spreading hopper 2 is connected to the mobile frame 1 through a fixed frame 11, and the material spreading hopper 2 is used to load corundum; The material plates 21 are symmetrically mounted at the front and rear ends of the outer wall of the spreading hopper 2. The material plates 21 can be used to place unopened bagged corundum so as to quickly complete the addition of corundum. A reinforcing rib is installed between the lower end surface of the material plate 21 and the outer wall of the material hopper 2. The reinforcing rib can effectively support the bottom of the material plate 21, increase the bearing capacity of the material plate 21, and is not easy to deform; The lower position of the spreading hopper 2 is symmetrically installed with an inclined support plate 3, and a slide rail 31 is symmetrically welded to any inclined support plate 3 flush with its side wall. A slider 32 is inserted into the slide rail 31, and a baffle 4 is fixedly installed on the side wall of the slider 32. The baffle 4 is used to seal the opening of the inclined support plate 3 to prevent overflow when spreading corundum; During the construction process, the slider 32 and the baffle 4 can be understood as an integrated part. The two slide down along the slide rail 31 under their own gravity, and the lower end surface of the baffle 4 is adaptively placed on the surface of the construction ground. When the moving frame 1 is moved, the lower end of the baffle 4 will slide on the construction ground; The outer surface of the inclined support plate 3 is symmetrically welded with a positioning plate 33, and a T-shaped rod 34 is fixedly installed on the side wall of the positioning plate 33. The outer wall of the T-shaped rod 34 is sleeved with a displacement plate 36. The outer wall of the T-shaped rod 34 and the displacement plate 36 are provided with an extrusion spring 35. The bottom of the displacement plate 36 is fixedly installed with a scraper 5. The scraper 5, the inclined support plate 3 and the baffle 4 are combined to form a spreading chamber. In this embodiment, the spreading chamber is approximately in the shape of an isosceles trapezoid. In this case, when diamond sand is spread, the generated dust can be suppressed in the spreading chamber as much as possible, effectively preventing it from directly drifting into the surrounding environment. The lower end surface of the scraper 5 contacts but is not connected to the upper end surface of the inclined support plate 3. In the initial state, the elastic force of the extrusion spring 35 pushes the displacement plate 36 to contact the end of the T-shaped rod 34. At this time, the scraper 5 is located at its lowermost position relative to the inclined support plate 3. In this position state, the lower end surface of the scraper 5 is flush with the lower end surface of the baffle 4, and the spreading chamber can be approximately understood as a sealed chamber. The outer surface of the inclined support plate 3 is symmetrically provided with an axis frame 37, and an axis rod 38 is transversely installed in the axis frame 37. A winding roller 381 is fixedly installed at the center of the outer ring of the axis rod 38. A traction rope 382 is wound around the outer wall of the winding roller 381. The traction rope 382 is a non-elastic member. The free end of the traction rope 382 is embedded in the head of the scraper 5. A driving wheel 39 is welded to one end face of the axis rod 38. Figure 4 As shown, the winding directions of the traction rope 382 on the two winding rollers 381 are opposite; The shaft 38 can rotate in the shaft frame 37. After the shaft 38 rotates, it can drive the winding roller 381 to rotate together. The rotating winding roller 381 winds the traction rope 382 around its outer wall. The end of the traction rope 382 applies a pulling force to the top of the scraper 5. The scraper 5 slides up along the inclined support plate 3. The displacement plate 36 slides along the outer wall of the T-bar 34 and compresses the extrusion spring 35. The extrusion spring 35 has a rebound force after being compressed. The end face of the bottom discharge port of the spreading hopper 2 is in an arc shape, and a spreading roller 6 is arranged at the position of the arc-shaped discharge port. A supporting shaft 61 is fixedly installed at the concentric position of both end faces of the spreading roller 6, and the supporting shaft 61 passes through the spreading hopper 2 and is rotatably connected thereto. A spreading hole 62 is opened at the center position of the spreading roller 6. The cross section of the spreading hole 62 is Y-shaped. In the initial state, Figure 4 The material spreading hole 62 is tilted relative to the material outlet, and the two do not overlap each other, so the diamond sand in the material spreading hopper 2 cannot fall out of the material spreading hole 62; A synchronous wheel 63 is concentrically mounted on the end surface of one of the supporting shafts 61. The synchronous wheel 63 is connected to the two driving wheels 39 through a synchronous belt 64. A lever 65 is fixedly mounted on the outer wall of the supporting shaft 61 on one side of the synchronous wheel 63. When the hopper 2 is filled with corundum, the construction worker manually holds the lever 65 and moves it along the Figure 1 As shown in the L direction deflection, the lever 65 drives the supporting shaft 61 to rotate together after the deflection. On the one hand, the rotation of the supporting shaft 61 drives the supporting shaft 61 and the spreading roller 6 to rotate, and the spreading hole 62 opened inside the spreading roller 6 gradually overlaps with the discharge port, and the two are connected to each other. The corundum inside the spreading hopper 2 falls to the construction ground along the discharge port and the spreading hole 62 to achieve the spreading effect. The overlapping area is determined by the deflection angle of the lever 65, and the size of the overlapping area determines the amount of corundum falling per unit time. The two are positively correlated within the normal range; On the other hand, after the support shaft 61 rotates, it drives the synchronous wheel 63 to rotate together. After the synchronous wheel 63 rotates, it drives the two driving wheels 39 to rotate through the synchronous belt 64, thereby realizing the rotation of the shaft rod 38 in the shaft frame 37, and the scraper 5 is lifted to a higher level. The spreading chamber is changed from the initial approximately sealed chamber to an open chamber. The open chamber refers to the gap between the bottom of the two scrapers 5 and the construction ground after sliding up along the inclined support plate 3. The gap value is the spreading thickness of the corundum, which is adjustable. At this time, when the mobile frame 1 is pushed to move, the scraper 5 on one side scrapes the corundum falling on the construction ground to keep its thickness consistent. In this embodiment, the adjustment process of the corundum spreading thickness is synchronously performed with the adjustment of the corundum falling amount, that is, the corundum thickness increases and the corundum falling amount increases synchronously, so as to avoid the waste of corundum material. In addition, the distribution of corundum can be accurately controlled according to the actual situation during the spreading process to avoid the accumulation or vacancy of corundum, and the construction of the floor surface is more neat. A limit track 66 is sleeved on the outer side of the top area of ​​the lever 65. When the lever 65 moves, its outer wall slides along the inner side of the limit track 66. The inner side wall of the limit track 66 locks the lateral position of the lever 65 to prevent the lever 65 from lateral deformation. A threaded hole 651 is provided inside the lever 65 at the upper position, and a threaded locking rod 652 is installed in the threaded hole 651. An arc plate 67 is fixedly installed on the outer side wall of the lever 65 on one side of the hopper 2. An arc-shaped silicone pad 68 is embedded in the outer end surface of the arc plate 67, and the arc-shaped silicone pad 68 is coaxial with the supporting shaft 61. When working, after the lever 65 is moved to the specified position, the threaded locking rod 652 can be rotated to screw into the threaded hole 651, and the end of the threaded locking rod 652 is pressed on the surface of the arc-shaped silicone pad 68, so that the arc-shaped silicone pad 68 is deformed and concave, and the position of the lever 65 is locked. When resetting, it is only necessary to reversely rotate the threaded locking rod 652 to separate its end from the arc-shaped silicone pad 68, and then reversely wave the lever 65. Among them, a steel ball is embedded in the connection between the slide rail 31 and the slider 32. At this time, the lifting and lowering between the two is changed from sliding friction to rolling friction, which increases the smoothness of the relative movement between the two. At the same time, an anti-fall rope is installed at the tail of the threaded locking rod 652, and the end of the anti-fall rope is embedded in the outer wall of the lever 65. If the threaded locking rod 652 is separated from the threaded hole 651, the anti-fall rope can lock the position of the threaded locking rod 652, that is, the threaded locking rod 652 will not fall to the ground.

[0022] In another embodiment, see Figure 3 The outer wall of the baffle 4 is symmetrically equipped with positioning wheels 41, and the lowest point of the positioning wheels 41 is lower than the lower end surface of the baffle 4. In this state, the positioning wheels 41 are in direct contact with the construction ground, and the bottom of the baffle 4 no longer slides on the construction ground, which reduces the wear on the bottom of the baffle 4. The height difference between the two is less than 2mm, which allows foreign impurity particles with a particle size of less than 2mm to pass through the bottom of the baffle 4; Furthermore, bending plates 42 are symmetrically installed on the side walls at both ends of the baffle 4, and the lower end surface of the bending plate 42 is flush with the lower end surface of the baffle 4. The bending plate 42 can increase the contact angle between the baffle 4 and the construction ground. When the construction ground is convex in the vertical direction, the high contact angle of the bending plate 42 can pass smoothly (the horizontal height of the baffle 4 is raised during the passing process) without affecting the continuity of the spreading operation.

[0023] In another embodiment, see Figure 1-Figure 8 A through hole 71 is provided at the center of the support shaft 61 at one end away from the lever 65, and the through hole 71 is connected to the material spreading hole 62. A round rod 72 is inserted transversely into the through hole 71, and a placement frame 73 is fixedly installed at a concentric position at one end of the round rod 72. The placement frame 73 is located in the material spreading hole 62, and anti-blocking rods 74 are arranged at equal intervals on the outer side of the placement frame 73 along the path direction thereof. The width of the anti-blocking rods 74 is controlled between 5-1 cm, and the anti-blocking rods 74 have edges and corners on both sides along the path direction of the material spreading hole 62, so as to reduce the contact area between the anti-blocking rods 74 and the corundum; The other end of the round rod 72 is rotatably connected to a driving rod 75 through a coupling. A rectangular groove 751 is provided on the end surface of the driving rod 75. An extrusion rod 752 is welded at the center of the bottom of the driving rod 75. A support plate 76 is installed on the fixed frame 11. A rectangular rod 761 is fixedly installed at the upper position of the inner wall of the support plate 76, and the rectangular rod 761 is inserted into the rectangular groove 751. When the falling amount of the diamond sand is adjusted in the above, the round rod 72 and the supporting shaft 61 rotate relative to each other. When the relative rotation occurs, the round rod 72 and the driving rod 75 rotate relative to each other. Since the position of the rectangular rod 761 remains unchanged and the rectangular rod 761 is inserted into the rectangular groove 751, the position of the driving rod 75 is the same as the initial state (the material spreading hole 62 is inclined relative to the discharge port); A support frame 77 is fixedly installed at the lower position of the inner wall of the support plate 76, and a driving shaft 78 is rotatably installed in the support frame 77. A driving roller 783 is concentrically installed at the end position of the driving shaft 78. An extrusion channel 784 is opened on the outer circular surface of the driving roller 783. The extrusion channel 784 is composed of two chamfered V-shaped grooves connected and combined. The extrusion rod 752 is located in the extrusion channel 784. A first sprocket 781 is fixedly installed on the outer wall of the driving shaft 78. A second sprocket 13 is installed on the driving wheel group. The first sprocket 781 and the second sprocket 13 are connected by a chain 782. During specific operation, when the mobile frame 1 is pushed to perform a spreading operation, the driving wheel group travels and rotates to drive the second sprocket 13 to rotate, and the second sprocket 13 drives the first sprocket 781 to rotate together through the chain 782, thereby driving the driving shaft 78 through the first sprocket 781. The support frame 77 rotates internally, and the driving roller 783 rotates synchronously with the driving shaft 78. The rotation of the driving roller 783 drives the extrusion channel 784 on its surface to rotate together and squeeze the extrusion rod 752, so that the extrusion rod 752 is subjected to the extrusion force of the inner wall of the extrusion channel 784. Since the position of the driving rod 75 is locked by the rectangular rod 761, the direction of the extrusion force can be understood as being parallel to the axial direction of the driving roller 783, that is, the extrusion rod 752 slides along the extrusion channel 784 while performing reciprocating motion in the axial direction of the driving roller 783. When the extrusion rod 752 reciprocates, it simultaneously drives the driving rod 75, the round rod 72 and the placement frame 73 to reciprocate. The placement frame 73 drives several anti-blocking rods 74 to reciprocate the corundum in the spreading hole 62, so that the corundum in this area is subjected to axial thrust, thereby avoiding the situation of corundum blockage during the spreading process, and the spreading process is smoother.

[0024] Further, such as Figure 1 and Figure 2As shown, a square hole 51 is provided at the center of the top of the scraper 5, a scale 52 is provided on the upper end surface of the inclined support plate 3 and in the area of ​​the square hole 51, and a pointer 53 is installed on the upper end surface of the scraper 5 near the square hole 51. In the initial state, the pointer 53 is aligned with the zero scale line of the scale 52. The marking unit on the scale 52 is millimeter, and the scale 52 scale indicates the ground clearance of the edge of the end surface of the scraper 5, which is the spreading thickness of the corundum. Under this condition, when the lever 65 is moved, the spreading thickness can be quickly known by visually observing the scale 52 without real-time measurement.
