DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0028] The following describes the railway construction gravel paving and leveling equipment according to an embodiment of the present application in conjunction with the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the railway construction gravel paving and leveling equipment of the embodiment of the present application may include a loading box 1, multiple first discharge pipes 2, two second discharge pipes 3, two leveling mechanisms 4, two transmission assemblies 5, two drive mechanisms 6 and two cleaning assemblies 7.

[0030] Among them, the two side walls and the bottom of the loading box 1 are respectively provided with multiple first discharge ports and multiple second discharge ports, and the multiple first discharge pipes 2 are respectively obliquely arranged on both sides of the loading box 1, and one end of the first discharge pipe 2 is in contact with the inner wall of the first discharge port, and the two second discharge pipes 3 are sequentially arranged below the loading box 1 along the length direction of the loading box 1, and one end of the second discharge pipe 3 is in contact with the inner wall of the second discharge port.

[0031] It should be noted that the first discharge pipe 2 and the second discharge pipe 3 described in this embodiment are both provided with gravel hopper solenoid valves to control the discharge speed, wherein the first discharge pipe 2 is arranged on the outside of the rail to lay gravel on both sides of the rail, and the second discharge pipe 3 is arranged between the two rails to lay gravel in the area between the two rails.

[0032] Furthermore, rollers are provided at the bottom of the loading box 1 , and the rollers run on rails. When laying gravel, the loading box 1 can be towed by a traction mechanism.

[0033] The second discharge pipe 3 is an inverted "Y"-shaped structure, and a plurality of third discharge ports 30 are distributed on the second discharge pipe 3. The plurality of third discharge ports 30 can achieve dispersed discharge and avoid accumulation of gravel, which is beneficial to the subsequent leveling process.

[0034] The side wall of the second discharge pipe 3 is provided with a slide rail 8, and a slide plate 9 is slidably connected to the slide rail 8. Two leveling mechanisms 4 are respectively arranged on the corresponding slide plates 9. The leveling mechanism 4 is used to disperse and level the gravel between the two rails. The two transmission components 5 are respectively connected to the corresponding leveling mechanisms 4. The driving mechanism 6 is arranged at the bottom of the loading box 1, and the two driving mechanisms 6 are respectively connected to the corresponding transmission components 5. The driving mechanism 6 is used to drive the leveling mechanism 4 to move back and forth.

[0035] It should be noted that the slide rail 8 described in this embodiment is arranged along the width direction of the loading box 1. Through the cooperation of the slide rail 8 and the slide plate 9, the moving direction of the leveling mechanism 4 can be restricted to ensure that the leveling mechanism 4 moves more stably.

[0036] Furthermore, the leveling mechanism 4 is located behind the second discharge pipe 3 (see Figure 4, the direction of the arrow is the travel direction of the loading box 1, and the travel direction is assumed to be forward), the transmission assembly 5 is connected to the leveling mechanism 4 and the driving mechanism 6 respectively, and the cooperation of the driving mechanism 6 and the transmission assembly 5 can drive the leveling mechanism 4 to move back and forth along the length direction of the slide rail 8 (perpendicular to the travel direction) to disperse the gravel between the two rails and level the gravel.

[0037] Two cleaning assemblies 7 are symmetrically arranged on the lower surface of the loading box 1, and the cleaning assembly 7 is arranged at the tail of the loading box 1. The cleaning assembly 7 is used to clean the gravel on both sides of the rail.

[0038] It should be noted that, in this embodiment, the end of the loading box 1 connected to the traction mechanism is the head, and the end of the loading box 1 away from the traction mechanism is the tail. After the gravel is laid, the cleaning component 7 can be used to clean the gravel around both sides of the rails to avoid laying too much gravel on both sides of the rails and affecting the use of the rails.

[0039] In order to further clarify the above embodiment, in one embodiment of the present application, Figure 4 As shown, the leveling mechanism 4 may include a plate sleeve 40, a plurality of springs 41, a first connecting plate 42, a plurality of spreading rods 43 and a plurality of leveling rods 44, wherein the plate sleeve 40 is arranged on the slide plate 9, a plurality of springs 41 are evenly distributed in the plate sleeve 40, the first connecting plate 42 is slidably connected to the plate sleeve 40, and the first connecting plate 42 is arranged at the bottom end of the spring 41, a plurality of spreading rods 43 are evenly distributed on the lower surface of the first connecting plate 42, and the spreading rods 43 are bent rods, and a plurality of leveling rods 44 are respectively connected to the corresponding spreading rods 43.

[0040] It should be noted that the bending direction of the paving rod 43 described in this embodiment is the traveling direction of the loading box 1, and the leveling rod 44 is in an "L"-shaped structure, and one end of the cross bar of the leveling rod 44 is connected to the paving rod 43, see Figure 4 , the leveling rod 44 is arranged on the left side of the paving rod 43 (the loading box 1 moves to the right).

[0041] Furthermore, through the cooperation of the spring 41 and the first connecting plate 42, the paving rod 43 can be protected. When large pieces of gravel hinder the movement of the paving rod 43, the paving rod 43 can squeeze the spring 41 upward to avoid damage to the paving rod 43.

[0042] In one embodiment of the present application, Figure 4As shown, the transmission assembly 5 may include a tooth plate 50, a gear 51, a sleeve 52 and a connecting shaft 53, wherein the tooth plate 50 is arranged on the side wall of the plate sleeve 40, a seat body 10 is provided on the lower surface of the loading box 1, the sleeve 52 is rotatably connected to the seat body 10, and a threaded groove 520 is provided on the inner wall of the sleeve 52, the gear 51 is arranged on the sleeve 52, and the gear 51 is meshingly connected to the tooth plate 50, the connecting shaft 53 is slidably connected to the seat body 10, and a slider 11 is provided on the outer wall of the connecting shaft 53, and the slider 11 is slidably connected to the threaded groove 520.

[0043] It should be noted that the tooth plate 50 is parallel to the plate sleeve 40. When the driving connecting shaft 53 moves horizontally, the mutual cooperation between the slider 11 and the threaded groove 520 can drive the sleeve 52 to rotate, and the sleeve 52 drives the gear 51 to rotate, thereby driving the tooth plate 50 to move back and forth.

[0044] In one embodiment of the present application, Figure 4 As shown, the driving mechanism 6 may include a motor 60, a driving shaft 61, a rotating rod 62 and a connecting rod 63, wherein the motor 60 is installed on the lower surface of the loading box 1, the driving shaft 61 is connected to the output end of the motor 60, one end of the rotating rod 62 is arranged on the driving shaft 61, the other end of the rotating rod 62 is hinged to the connecting rod 63, and the end of the connecting rod 63 facing away from the rotating rod 62 is hinged to the end of the connecting shaft 53.

[0045] In an embodiment of the present application, the motor 60 can drive the driving shaft 61 to rotate, and the rotating rod 62 and the connecting rod 63 cooperate to drive the connecting shaft 53 to reciprocate along the travel direction of the loading box 1, and then with the cooperation of the transmission assembly 5, the leveling mechanism 4 is driven to reciprocate, and finally the gravel is evenly dispersed.

[0046] In one embodiment of the present application, Figure 2 As shown, a guide block 12 with a high middle and low ends is provided between the first discharge port and the second discharge port. The guide block 12 can guide the crushed stones to prevent the crushed stones from accumulating at the bottom of the loading box 1 so as to completely empty the crushed stones.

[0047] In one embodiment of the present application, Figure 7 As shown, the cleaning assembly 7 may include a shovel plate 70, a second connecting plate 71, a support plate 72, two center shafts 73 and two plow plates 74, wherein the second connecting plate 71 is arranged on the lower surface of the loading box 1, the shovel plate 70 is connected to the second connecting plate 71, and the shovel plate 70 is wrapped around the rail, the support plate 72 is connected to the second connecting plate 71, the two center shafts 73 are symmetrically arranged on the lower surface of the support plate 72, and the two plow plates 74 are rotatably connected to the corresponding center shafts 73 respectively.

[0048] It should be noted that the angle between the plowboard 74 and the shovelboard 70 described in this embodiment can be adjusted according to actual needs, and the shovelboard 70 does not contact the rails. The shovelboard 70 can be used to clear the gravel on both sides of the rails, and the plowboard 74 can be used to prevent the gravel from being thrown a long distance.

[0049] Furthermore, the shovel plate 70 is a "U"-shaped plate with an opening facing downward, and the two side plates of the shovel plate 70 expand outward. In order to improve the stability of the shovel plate 70 when moving, a plurality of rollers may be provided inside the shovel plate 70, and the rollers roll on the rails to support the shovel plate 70.

[0050] Furthermore, if Figure 7 and Figure 8 As shown, a positioning groove 740 is provided on the upper surface of the plowboard 74 , and a plurality of positioning holes 720 are penetrated through the support plate 72 . Locking rods 13 are provided in the positioning grooves 740 and the positioning holes 720 .

[0051] It should be noted that the locking rod 13 described in this embodiment passes through the positioning hole 720, and one end of the locking rod 13 is inserted into the positioning groove 740. The position of the plowboard 74 can be locked by the locking rod 13, and adjustment is convenient.

[0052] Furthermore, in order to facilitate the rotation of the moldboard 74 , a handle may be provided on the upper surface of the moldboard 74 .

[0053] Specifically, when laying gravel, the loading box 1 is filled with gravel and towed by a traction mechanism. When the loading box 1 reaches the road section where gravel needs to be laid, relevant personnel can control the gravel hopper solenoid valve to open and control the motor 60 to start.

[0054] The crushed stones pass through the first discharge pipe 2 and the second discharge pipe 3 and fall on both sides of the rail and between the two rails respectively. At the same time, since the second discharge pipe 3 is provided with a plurality of third discharge ports 30, the crushed stones can be discharged from the third discharge ports 30, thereby avoiding the accumulation of the crushed stones when they are discharged from the third discharge ports 30 alone, which is not conducive to the subsequent paving and leveling work.

[0055] When the motor 60 is started, it can drive the driving shaft 61 to rotate, and through the cooperation of the rotating rod 62 and the connecting rod 63, drive the connecting shaft 53 to move back and forth. With the cooperation of the threaded groove 520 and the slider 11, it can drive the sleeve 52 and the gear 51 to rotate forward and reverse, and through the cooperation of the toothed plate 50, drive the leveling mechanism 4 to move back and forth. At the same time, because the leveling mechanism 4 also moves with the loading box 1, the spreading rod 43 can be used to preliminarily spread the gravel between the two rails, and the reciprocating leveling rod 44 can be used to level the gravel.

[0056] At the same time, during the movement of the shovel board 70, the gravel around both sides of the rails can be cleaned, and the plow board 74 can be used to guide and transport the gravel to avoid excessive gravel around the rails, thereby ensuring the safety of railway transportation.

[0057] In summary, the railway construction gravel laying and leveling equipment of the embodiment of the present application performs gravel leveling operations simultaneously during the gravel laying process, which is not only easy to operate, but also effectively reduces the subsequent work steps, and significantly improves the overall efficiency of gravel laying. At the same time, it can also clean up the gravel on both sides of the rails in real time, further ensuring the safety and reliability of rail operation.
