Description

Technical Field

[0001] This application relates to the field of winch technology, and in particular to sand suction winches. Background Technology

[0002] A sand suction winch, as the name suggests, is used for winding and unwinding the hose of a sand suction pump. It is extremely large and heavy. A typical sand suction winch includes a frame, a drum, and a drive unit. The drive unit rotates the drum on the frame to store and unwind the hose. Regarding the aforementioned related technologies, the inventor believes that in current sand suction winches, when the hose is wound on the drum, the unwound hose piles up disorderly, causing friction between the hoses. This leads to wear and tear on the hose during winding, ultimately damaging it. Utility Model Content

[0003] The purpose of this application is to provide a sand suction winch to improve the current sand suction winch problem where, when the hose is wound on the drum, the unused hose piles up disorderly on the drum, causing friction between the hoses, which leads to wear and damage to the hoses during winding.

[0004] The sand suction winch provided in this application adopts the following technical solution:

[0005] A sand suction winch includes a winch support, a drum rotatably mounted on the winch support for winding a sand suction hose, a drive component for driving the drum to rotate, a mounting base at the end of the winch support away from the drum, a movable frame for supporting the sand suction hose that is reciprocating on the mounting base, and a clamping frame for receiving the sand suction hose on the movable frame.

[0006] By adopting the above technical solution, a drive component is installed on the winch support. The drive component drives the drum to rotate and wind up the sand suction hose. A reciprocating moving frame is set on the mounting base. The clamping frame on the moving frame supports the sand suction hose and prevents the hose from being dragged on the ground and causing wear. The reciprocating movement of the moving frame ensures that the sand suction hose is evenly distributed on the drum when the drum rotates, reducing the possibility of wear caused by disorderly accumulation and compression between the sand suction hoses and damage to the sand suction hose.

[0007] Optionally, the mounting base is rotatably provided with a reciprocating screw adapted to the movable frame, the mounting base is provided with a guide groove along the length direction of the reciprocating screw, the movable frame is slidably connected to the inner side wall of the guide groove, and the mounting base is provided with a second driving component for driving the reciprocating screw to rotate and causing the movable frame to move back and forth.

[0008] By adopting the above technical solution, the reciprocating screw is driven to rotate by the second drive component on the mounting base, so that the clamping frame on the moving frame moves back and forth with the sand suction hose, so that the hose is evenly distributed on the drum. A guide groove is opened on the mounting base in the opposite direction along the length of the reciprocating screw, and the moving frame is slidably connected to the inner wall of the guide groove, so that the moving frame can move smoothly and prevent the moving frame from deflecting when it moves with the rotation of the reciprocating screw.

[0009] Optionally, the clamping frame is located above the movable frame and is rotatably connected to the movable frame, and the clamping frame is rotatably equipped with rollers that fit against the side wall of the sand suction hose.

[0010] By adopting the above technical solution, the rollers on the clamping frame rotate with the movement of the suction hose when it is being wound up, reducing the friction on the hose. At the same time, the clamping frame can rotate at a certain angle on the moving frame when the suction hose is being wound up by the drum, reducing the friction between the hose and the clamping frame and reducing the possibility of damage to the hose.

[0011] Optionally, the clamping frame has grooves at both ends of the roller, and a fixing block is slidably connected in the groove. The fixing block is rotatably connected to the roller, and an elastic element is provided between the fixing block and the inner wall of the groove.

[0012] By adopting the above technical solution, grooves are opened at both ends of the clamping frame and fixed blocks are slidably installed in the grooves. The rollers are rotatably connected to the fixed blocks. An elastic element is installed between the fixed blocks and the inner wall of the groove. The elastic element pushes the fixed blocks and rollers on both sides of the suction hose closer to each other to clamp and fix the hose, preventing the hose from being squeezed between the hose and the roller due to the excessive winding speed of the drum, which would damage the hose.

[0013] Optionally, the two ends of the drum are provided with baffles extending in the radial direction of the drum. The baffles abut against the side wall of the suction hose being wound by the drum. The baffles are hollowed out and have an arc surface near the edge of the drum.

[0014] By adopting the above technical solution, the baffle restricts the suction hose on the drum, preventing the hose from loosening and falling from both ends of the drum, thus affecting the winding operation. The baffle is hollowed out to reduce the weight of the overall device. The baffle is provided with an arc surface near the edge of the drum to reduce the possibility of the hose being directly in contact with the edge of the baffle during winding, which could cause the hose to bend.

[0015] Optionally, the arcuate sidewall of the drum is provided with a baffle, which is spirally distributed around the outer sidewall of the drum.

[0016] By adopting the above technical solution, the arc-shaped sidewall of the drum is provided with spirally distributed baffles, so that when the drum is winding up the suction hose, the hose on the drum can be wound along the spiral baffles, reducing the possibility of the hoses getting tangled and squeezed together, and causing damage to some of the hoses.

[0017] Optionally, the drum has grooves between the spirally distributed baffles that fit into the suction hose, and the grooves are spirally arranged on the side wall of the drum along the direction of the baffles.

[0018] By adopting the above technical solution, a groove is provided between the spirally distributed baffles on the drum. The groove is spirally arranged on the side wall of the drum along the direction of the baffles, so that the side wall of the hose fits against the inner side wall of the groove, and the position of the hose is determined. When the drum winds up the hose, the hose can be wound up on the drum more quickly along the groove between the baffles, further reducing the damage to the hose caused by mutual friction between the hoses.

[0019] Optionally, the side of the baffle away from the drum is provided with an arc-shaped protrusion corresponding to the side wall of the suction hose.

[0020] By adopting the above technical solution, an arc-shaped raised surface is provided on the side of the spirally distributed baffle away from the drum, allowing the hose to slide down along the arc-shaped raised surface when it is pressed above the baffle, thus reducing the possibility of damage to the hose.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Install drive component one on the winch support. Drive component one drives the drum to rotate and wind up the sand suction hose. A reciprocating moving frame is set on the mounting base. The clamping frame on the moving frame supports the sand suction hose to prevent wear caused by dragging the hose on the ground. The reciprocating movement of the moving frame ensures that the sand suction hose is evenly distributed on the drum when the drum rotates, reducing the possibility of wear caused by disorderly accumulation and compression between the sand suction hoses and damage to the sand suction hose.

[0023] 2. Slide grooves are opened at both ends of the clamping frame and fixed blocks are slidably installed in the slide grooves. The rollers are rotatably connected to the fixed blocks. Elastic elements are installed between the fixed blocks and the inner sidewalls of the slide grooves. The elastic elements push the fixed blocks and rollers on both sides of the suction hose closer to each other to clamp and fix the hose, preventing the hose from being squeezed between the hose and the rollers due to the excessive winding speed of the drum, which would damage the hose.

[0024] 3. A groove is provided between the spirally distributed baffles on the drum. The groove is spirally arranged on the side wall of the drum along the direction of the baffles, so that the side wall of the hose fits against the inner side wall of the groove. This determines the position of the hose, so that when the drum winds up the hose, the hose can be wound up on the drum more quickly along the groove between the baffles, further reducing the damage to the hose caused by mutual friction between the hoses.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0029] Sand suction winch, see reference Figure 1 The system includes a winch support 1, which is rotatably connected to a drum 2 via bearings and a shaft on the car support. A drive component 3 is installed on the winch support 1. The drive component 3 is a drive motor connected to a power source. The output end of the drive motor drives the drum 2 to rotate via a reducer, thereby causing the drum 2 to wind up and unwind the sand suction hose. Metal baffles 21 extending radially to both ends of the drum 2 are welded to the drum 2. The metal baffles 21 are fixed to the shaft. When the drum 2 winds up the sand suction hose, the baffles 21 restrict the sand suction hose on the drum 2 to prevent the hose from loosening and falling from both ends of the drum 2, thus affecting the winding operation of the drum 2.

[0030] Reference Figure 1 and Figure 2 A spirally distributed metal baffle 22 is welded to the arc-shaped sidewall of the drum 2. When the drum 2 winds up the suction hose, the hose on the drum 2 can be wound along the spiral baffle 22, reducing the possibility of the hose tangling and being squeezed together, thus preventing damage to some parts of the hose. A groove 23 is provided between the spirally distributed baffles 22 on the drum 2. The groove 23 is spirally arranged on the sidewall of the drum 2 along the direction of the baffle 22, so that the sidewall of the hose fits against the inner sidewall of the groove 23, determining the position of the hose. When the drum 2 winds up the hose, the hose can be wound up on the drum 2 more quickly along the groove 23 between the baffles 22, further reducing the damage to the hose caused by friction between the hoses.

[0031] Reference Figure 1 and Figure 2A mounting base 4 is bolted to one end of the winch bracket 1. A movable frame 5 is mounted on the mounting base 4. The mounting base 4 is rotatably connected to the reciprocating screw 41 via bearings. The reciprocating screw 41 and the movable frame 5 cooperate with each other. A second driving component 43 is mounted on the mounting base 4. The second driving component 43 is a drive motor connected to the power supply. The second driving component 43 drives the reciprocating screw 41 to rotate, thereby moving the movable frame 5 back and forth on the reciprocating screw 41. This ensures that the movable frame 5, carrying the hose, is evenly arranged on the drum 2, reducing the possibility of disorderly accumulation and compression of the empty hoses. A guide is provided on the mounting base 4 in the opposite direction along the length of the reciprocating screw 41. A slider adapted to the guide groove 42 is bolted to the bottom of the movable frame 5, so that the movable frame 5 can move smoothly and prevent the movable frame 5 from deflecting when it moves with the reciprocating screw 41. The movable frame 5 is rotatably connected to the clamping frame 6 through a rotating shaft. The clamping frame 6 is equipped with rollers 61 to support and fix the sand suction hose, so that the clamping frame 6 can deflect at a certain angle, so that the hose is reduced from friction between the hose and the clamping frame 6 when the hose is wound by the drum 2. The contact surface between the roller 61 and the hose is concave, which increases the contact area between the hose and the roller 61 and reduces the possibility of the hose falling off the roller 61.

[0032] Reference Figure 1 and Figure 2 The clamping frame 6 has grooves 62 at both ends of the roller 61. Fixing blocks 63 are slidably installed in the grooves 62. The roller 61 and the fixing blocks 63 are rotatably connected by bearings. A spring 64, which acts as an elastic element, is installed between the fixing blocks 63 and the inner wall of the grooves 62. The spring pushes the fixing blocks 63 and the roller 61 on both sides of the hose to move closer to each other, clamping and fixing the hose. This prevents the hose from being squeezed between the hose and the roller 61 due to the excessive winding speed of the drum 2, which would damage the hose. The baffle 21 is hollowed out to reduce the weight of the overall device. The baffle 21 has an arc surface near the edge of the drum 2 to reduce the possibility of the hose being directly pressed against the edge of the baffle 21 during winding, which could cause the hose to bend. The spirally distributed baffle 22 has an arc protrusion 221 on the side away from the drum 2, so that when the hose is pressed above the baffle 22, it can slide down along the arc protrusion 221, reducing the possibility of the hose being damaged.

[0033] The implementation principle of this application embodiment is as follows:

[0034] In actual operation, the drive component 3 of the winch support 1 drives the drum 2 to rotate through the reducer, so that the drum 2 winds up the sand suction hose. When the drum 2 winds up the sand suction hose, the drive component 43 on the mounting base 4 drives the reciprocating screw 41 to rotate, so that the clamping frame 6 on the moving frame 5 moves back and forth with the sand suction hose. The roller 61 on the clamping frame 6 rotates with the movement of the hose when the sand suction hose is wound up, reducing the friction on the hose. At the same time, the clamping frame 6 rotates at a certain angle on the moving frame 5, reducing the possibility of friction between the hose and the clamping frame 6. The sand suction hose is arranged on the drum 2 along the spirally distributed baffles 22 and the grooves 23 between the baffles 22. The baffles 22 separate the sand suction hose, reducing the possibility of the hose being damaged by disorderly accumulation and compression of the empty hose during the winding process. The reciprocating movement of the moving frame 5 makes the sand suction hose evenly distributed on the drum 2, reducing the possibility of wear and damage to the sand suction hose caused by disorderly accumulation and compression between the sand suction hoses. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
