Description

Technical Field

[0001] This utility model relates to the field of trolleys, and in particular to a multi-purpose trolley for pressing high-pressure hoses. Background Technology

[0002] In mining operations such as coal mines, the hydraulic system is one of the core systems that ensures the normal operation of mining face equipment. In order to ensure the normal operation of hydraulic hoses, the hydraulic hoses need to be pressed during assembly to ensure a tight connection between the hoses and the joints. However, the hydraulic hoses themselves can also cause some inconvenience during subsequent maintenance.

[0003] In existing technologies, hydraulic hoses are typically packaged and stored in rolls of approximately 50 meters each. This design facilitates both transportation and management. However, in actual maintenance operations, whenever hydraulic hoses need to be replaced or adjusted, the heavy hose rolls must be moved from the warehouse to the work site. This process often requires multiple people working together, as the weight and volume of a single hose roll are considerable. Slight carelessness during handling can lead to personal injury or hose damage. Furthermore, when unwinding the coiled hose, it must be carefully unwound to avoid excessive stretching or twisting, which could affect its service life. Therefore, the labor intensity for workers is extremely high in both handling and unwinding the coils, often requiring close cooperation between two to three workers to complete smoothly. In narrow alleys or confined work areas, such operations are not only inefficient but also increase the risk of workplace accidents. Therefore, there is a need to develop a multi-purpose trolley for pressing high-pressure hoses to solve these problems. Utility Model Content

[0004] In order to overcome the problem that traditional manual operation methods greatly increase the labor intensity of workers and are inefficient when carrying out maintenance work.

[0005] The technical solution of this utility model is as follows: a multi-purpose trolley for pressing high-pressure rubber hoses, including a movable base and a first sliding block. The first sliding block is slidably connected to the movable base. A coiling rotating shaft for coiling is rotatably connected to the first sliding block. A first connecting steel bar is fixedly connected to the coiling rotating shaft. A coiling turntable frame for supporting the coiled rubber hose is fixedly connected to the first connecting steel bar. A coiling handwheel for controlling the rotation of the coiling rotating shaft is fixedly connected to the coiling base. A second sliding block is slidably connected to the movable base. An unfolding turntable shaft for unwinding is rotatably connected to the second sliding block. A second connecting steel bar is fixedly connected to the unfolding turntable shaft. An unfolding turntable frame for supporting the rubber hose is fixedly connected to the second connecting steel bar. An unfolding coiling frame is fixedly connected between the unfolding turntable frame and the unfolding turntable shaft.

[0006] Preferably, the movable base is provided with a sliding groove, and the first sliding block and the rotating shaft of the reel are both slidably connected to the sliding groove.

[0007] Preferably, the first sliding block has a limiting groove at the relative position of the rotating shaft of the coil, and the rotating shaft of the coil is rotatably connected inside the groove.

[0008] Preferably, the second sliding block has a groove at the relative position of the unfolding turntable shaft, and the unfolding turntable shaft is rotatably connected to the groove.

[0009] Preferably, a first motor is fixedly connected to the movable base, and a bidirectional threaded rod for adjusting the distance between the second sliding block and the first sliding block is fixedly connected to the output end of the first motor. The first sliding block and the second sliding block are threadedly connected to the bidirectional threaded rod. A second motor is fixedly connected to the movable base, and a fixed seat is fixedly connected to the movable base. A first rotating shaft is fixedly connected to the output end of the second motor, and a first transmission wheel is fixedly connected to the first rotating shaft. A transmission belt is driven through the first transmission wheel. A first bevel gear is fixedly connected to the first rotating shaft, and a second bevel gear meshes with the first bevel gear. The second bevel gear is rotatably connected to the fixed seat, and a first threaded rod is fixedly connected to the second bevel gear. A limit block is fixedly connected to one end of the first threaded rod, and a sliding bracket is threadedly connected to the first threaded rod. The sliding bracket is slidably connected to the fixed seat, and a support rod is fixedly connected to the sliding bracket. A support base for support is movably connected to one end of the support rod.

[0010] Preferably, there are two fixed seats, two first rotating shafts, and two first transmission wheels. The two fixed seats are symmetrically fixedly connected to the movable base, the two first rotating shafts are rotatably connected to the two fixed seats respectively, and the two first transmission wheels are fixedly connected to one end of the two first rotating shafts respectively, and the transmission belt is connected between the two first transmission wheels.

[0011] Preferably, the fixed base has a groove at the relative position of the sliding bracket, and the sliding bracket is slidably connected to the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. During maintenance, the rotation of the unfolding turntable shaft and the coiling rotating shaft allows workers to wind and unwind the hose. The movable base replaces manual handling. To unwind, simply drag the hose head gently in the desired direction to rotate the unfolding turntable shaft and unfold the hose coil. To wind, clamp the hose onto the coiling turntable frame and turn the coiling handwheel to wind it. Compared to the traditional manual winding method, this greatly reduces the workload of the two winding and unwinding processes, thus effectively improving work efficiency.

[0014] 2. When the mobile base moves to the required position to carry out unwinding and rewinding, the second motor works to drive the sliding bracket to slide and support the mobile base through the support rod and the rotating shaft of the coil, so that the moving wheels of the mobile base are away from the ground, providing a stable environment for unwinding and rewinding, and preventing the mobile base from moving during unwinding and rewinding, which would affect the workers' unwinding and rewinding work.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 3This utility model provides an embodiment: a multi-purpose trolley for pressing high-pressure rubber hoses, including a movable base 1 and a first sliding block 21. The first sliding block 21 is slidably connected to the movable base 1. A coiling rotating shaft 22 for coiling is rotatably connected to the first sliding block 21. A first connecting steel bar 23 is fixedly connected to the coiling rotating shaft 22. A coiling turntable frame 24 for supporting the coiled rubber hose is fixedly connected to the first connecting steel bar 23. A coiling handwheel 25 for controlling the rotation of the coiling rotating shaft 22 is fixedly connected to the coiling rotating shaft 22. A second sliding block 26 is slidably connected to the movable base 1. An unfolding turntable shaft 27 for unwinding is rotatably connected to the second sliding block 26. A second connecting steel bar 28 is fixedly connected to the unfolding turntable shaft 27. A second connecting steel bar 28 is fixedly connected to the second connecting steel bar 28. A turntable 29 for supporting the hose is connected. A turntable 210 is fixedly connected between the turntable 29 and the turntable shaft 27. During maintenance, the hose roll is placed on the turntable 29, and the hose roll is moved to the required position by the movable base 1 so that the staff can carry out maintenance work. After the movable base 1 is moved to the required position, the roll packaging bag is opened, and the tube end is gently dragged in the required direction. When rotating, the turntable shaft 27 is rotated to unwind the hose. When it is necessary to rewind, one end of the hose to be rewound is clamped on the rewinding turntable 24, and the rewinding handwheel 25 is turned to rewind the hose. After rewinding, the rewound hose is moved to the required position again by the movable base 1 so that the staff can complete the maintenance work.

[0023] Please see Figure 1 - Figure 5In this embodiment, a sliding groove is provided on the movable base 1. The first sliding block 21 and the coil rotating shaft 22 are both slidably connected to the sliding groove. The sliding groove guides the sliding of the first sliding block 21 and the coil rotating shaft 22, preventing them from shifting and affecting the subsequent unwinding and rewinding of the hose. The first sliding block 21 has a limiting groove at the relative position of the coil rotating shaft 22. The coil rotating shaft 22 is rotatably connected inside the groove, which restricts the rotation of the coil rotating shaft 22 and prevents it from disengaging from the first sliding block 21 when rotating. When the hose needs to be rewound, the hose is clamped on the coil turntable frame 24 and the turntable is rotated. The rotating shaft 22 replaces manual labor in winding the hose, reducing the workload of workers. The second sliding block 26 has a groove at a position opposite to the unfolding turntable shaft 27. The unfolding turntable shaft 27 is rotatably connected to the groove, which restricts its rotation and prevents it from disengaging from the second sliding block 26 during rotation. After the moving base 1 moves the entire roll of hose to the desired area, the packaging is opened, and the hose head is gently dragged in the desired direction to rotate the unfolding turntable shaft 27, allowing workers to unwind the hose roll. A first motor 211 is fixedly connected to the moving base 1, and a bidirectional threaded rod 212 is fixedly connected to the output end of the first motor 211 to adjust the distance between the second sliding block 26 and the first sliding block 21. The first sliding block 21 and the second sliding block 26 are threadedly connected to the bidirectional threaded rod 212. A second motor 213 is fixedly connected to the movable base 1, and a fixed seat 214 is fixedly connected to the movable base 1. A first rotating shaft 215 is fixedly connected to the output end of the second motor 213. A first transmission wheel 223 is fixedly connected to the first rotating shaft 215, and a transmission belt 224 is driven through the first transmission wheel 223. A first bevel gear 216 is fixedly connected to the first rotating shaft 215, and a second bevel gear 217 meshes with the first bevel gear 216. The second bevel gear 217 is rotatably connected to the fixed seat 214, and a first threaded rod 218 is fixedly connected to the second bevel gear 217. A limit block is fixedly connected to one end of the first threaded rod 218. 219. A sliding bracket 220 is threadedly connected to the first threaded rod 218. The sliding bracket 220 is slidably connected to the fixed seat 214. A support rod 221 is fixedly connected to the sliding bracket 220. One end of the support rod 221 is movably connected to a support base 222 for support. By rotating the bidirectional threaded rod 212, the first sliding block 21 and the coil rotating shaft 22 slide synchronously to adjust the distance between the first sliding block 21 and the coil rotating shaft 22, so that the operator can rewind and unwind the hose. Two fixed seats 214, two first rotating shafts 215, and two first transmission wheels 223 are provided. The two fixed seats 214 are symmetrically fixedly connected to the movable base 1, and the two first rotating shafts 215 are rotatably connected to the two fixed seats 214 respectively.Two first transmission wheels 223 are respectively fixedly connected to one end of two first rotating shafts 215, and a transmission belt 224 is driven between the two first transmission wheels 223. Through the cooperation of the two first transmission wheels 223 and the transmission belt 224, the first rotating shafts 215 on both sides rotate synchronously, thereby causing the sliding bracket 220 connected to its fixed seat 214 to slide synchronously. This causes the support rod 221 and the support base 222 to support the movable base 1, preventing the movable base 1 from moving during winding and unwinding, thus affecting the operator's work. The fixed seat 214 has a groove at the relative position of the sliding bracket 220, and the sliding bracket 220 is slidably connected to the groove. The groove restricts the sliding of the sliding bracket 220, preventing it from tilting during sliding and affecting the support provided by the support rod 221 and the support base 222.

[0024] During maintenance, the first motor 211 operates, driving the bidirectional threaded rod 212 to rotate. The rotation of the bidirectional threaded rod 212 adjusts the distance between the second sliding block 26 and the first sliding block 21. After the hose coil is placed on the unfolding turntable 29, the movable base 1 moves the hose coil to the desired position. The second motor 213 operates, driving the first rotating shaft 215 to rotate. The rotation of the first rotating shaft 215 drives the first bevel gear 216 to rotate. The rotation of the first bevel gear 216, in conjunction with the second bevel gear 217, drives the first threaded rod 218 to rotate. The rotation of the first threaded rod 218 causes the sliding bracket 220 to slide. When the bracket 220 slides, it drives the support rod 221 and the support base 222 to move, and supports the movable base 1 through the support rod 221 and the support base 222 to facilitate maintenance work. After the movable base 1 is moved to the required position, the coil packaging bag is opened, and the tube head is gently dragged in the required direction. When rotating, it drives the unfolding turntable shaft 27 to rotate, thereby unwinding the hose. When it is necessary to rewind, one end of the hose to be rewound is clamped on the rewinding turntable frame 24, and the rewinding handwheel 25 is turned to drive the hose to rewind. After rewinding, the rewound hose is moved to the required position again through the movable base 1 so that the maintenance work can be completed.

[0025] Through the above steps, during maintenance, the rotation of the turntable shaft 27 and the coil rotating shaft 22 is unfolded so that the staff can rewind and unwind the hose. The hose is moved by its movable base 1 to replace manual handling, thus solving the problem that the traditional manual operation method greatly increases the labor intensity of workers and is inefficient when carrying out maintenance work.
