It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1 - 5As shown in the figure, the utility model provides a roller brush replacement device for a loader-type sweeper, which includes: a bottom plate 1, a support frame 2 is fixedly connected to the top of the bottom plate 1, a cross beam 3 is fixedly connected to the top of the support frame 2, a first U-shaped frame 4 is fixedly connected to the top of the cross beam 3, a first motor 7 is fixedly connected to the outer surface of the first U-shaped frame 4, the output end of the first motor 7 rotates through the outer surface of the first U-shaped frame 4, the output end of the first motor 7 is fixedly connected to a roller 5, the roller 5 is rotatably connected to the first U-shaped frame 4, a steel cable 6 is arranged on the outer surface of the roller 5, and a clamping assembly 8 is arranged at the end face of the steel cable 6; the clamping assembly 8, the clamping assembly 8 includes a mounting frame 801, clamping blocks 804 are symmetrically arranged inside the mounting frame 801, fixed blocks 806 are symmetrically and fixedly connected to the front surface of the mounting frame 801, a second motor 802 is fixedly connected to the outer surface of one of the fixed blocks 806, the output end of the second motor 802 rotates through the outer surface of the fixed block 806, the output end of the second motor 802 is fixedly connected to a bidirectional threaded rod 807, the bidirectional threaded rod 807 is rotatably connected to the other fixed block 806, an internally threaded block 805 is fixedly connected to the front surface of the clamping block 804, the inner surface of the internally threaded block 805 is in threaded rotation connection with the outer surface of the bidirectional threaded rod 807, guide rods 803 are symmetrically fixedly connected to the outer surface of the clamping block 804, and the outer surfaces of the two guide rods 803 all slide through the outer surface of the mounting frame 801. A second U-shaped frame 9 is fixedly connected to the top of the cross beam 3 at a position far from the first U-shaped frame 4, a pulley 10 is rotatably connected to the inner surface of the second U-shaped frame 9, and the pulley 10 is arranged in a matching manner with the steel cable 6.

[0025] The effect achieved by the entire Embodiment 1 is that when replacing the rolling brush of the loader-type sweeper, first, the operator uses tools to remove the brush roller of the loader-type sweeper and place it on the ground. Then, start the first motor 7. The output end of the first motor 7 rotates in the reverse direction, driving the roller 5 to rotate synchronously inside the first U-shaped frame 4, so that the steel cable 6 wound on its surface is released outward. One end of the steel cable 6 is fixedly connected to the surface of the roller 5, and the other end of the steel cable 6 is fixedly connected to the mounting frame 801. After the steel cable 6 is released for a certain distance, the mounting frame 801 connected to the steel cable 6 descends, facilitating the operator to guide the mounting frame 801 to dock with the removed sweeper brush roller, so that one end of the brush roller is located between the two clamping blocks 804. Start the second motor 802. When the output end drives the bidirectional threaded rod 807 to rotate forward inside the inner wall of the fixed block 806, the two internal threaded blocks 805 rotate threadedly with the bidirectional threaded rod 807, driving the two clamping blocks 804 to move towards each other.

Start the first motor 7. The output end of the first motor 7 rotates forward, driving the roller 5 to wind up the steel cable 6. Under the winding and traction of the roller 5, the steel cable 6 slides synchronously on the surface of the pulley 10, and the pulley 10 rotates synchronously between the inner walls of the second U-shaped frame 9, avoiding the friction between the steel cable 6 and the cross beam 3, playing a role in reducing the winding resistance of the roller 5. When the mounting frame 801 drives the clamped and fixed brush roller to rise and hang above the ground, it is convenient for the operator to take out and replace the rolling brush arranged on its surface from bottom to top, solving the problem in the background technology that when replacing the rolling brush of the sweeper, a special person is required to drive and operate a mobile machine and cooperate with the replacement personnel to lift the brush roller, resulting in a large number of personnel for cooperative replacement and maintenance, and an increase in labor and mechanical costs.

[0026] Embodiment 2: As Figures 1 - 5 shown, trapezoidal blocks 12 are symmetrically and fixedly connected to the outer surfaces on both sides of the support frame 2 respectively. The bottoms of the multiple trapezoidal blocks 12 are fixedly connected to the top of the bottom plate 1. Reinforcement blocks 11 are fixedly connected to the outer surfaces on both sides of the cross beam 3 respectively. The opposite surfaces of the two reinforcement blocks 11 are fixedly connected to the outer surfaces on both sides of the support frame 2 respectively.

[0027] The effect achieved by the entire Embodiment 2 is that during use, by fixedly connecting multiple trapezoidal blocks 12 between the outer surfaces on both sides of the support frame 2 and the top of the bottom plate 1, it plays a role in strengthening the strength of the support frame 2. By fixedly connecting the reinforcement blocks 11 to the outer surfaces on both sides of the cross beam 3 and the support frame 2 respectively, it plays a role in increasing the support for the cross beam 3, improving the stability of the overall device during operation.

[0028] Working principle: When replacing the roller brush of a loader-type sweeper, first, the operator uses tools to remove the brush roller of the loader-type sweeper and place it on the ground. Then, start the first motor 7. The output end of the first motor 7 rotates in the reverse direction, driving the roller 5 to rotate synchronously inside the first U-shaped frame 4, so that the steel cable 6 wound on its surface is released outward. One end of the steel cable 6 is fixedly connected to the surface of the roller 5, and the other end of the steel cable 6 is fixedly connected to the mounting frame 801. After the steel cable 6 is released for a certain distance, the mounting frame 801 connected to the steel cable 6 descends, facilitating the operator to guide the mounting frame 801 to dock with the removed sweeper brush roller, so that one end of the brush roller is located between the two clamping blocks 804. Start the second motor 802. When the output end drives the bidirectional threaded rod 807 to rotate forward inside the inner wall of the fixed block 806, the two internal threaded blocks 805 rotate in threaded connection with the bidirectional threaded rod 807, driving the two clamping blocks 804 to move towards each other. At the same time, multiple guide rods 803 slide synchronously inside the inner wall of the mounting frame 801 until the arc surfaces of the two clamping blocks 804 are in close contact with the surface of the brush roller, playing a role in clamping and fixing the surface of the brush roller. Start the first motor 7. The output end of the first motor 7 rotates forward, driving the roller 5 to wind up the steel cable 6. Under the winding and traction of the roller 5, the steel cable 6 slides synchronously on the surface of the pulley 10, and the pulley 10 rotates synchronously between the inner walls of the second U-shaped frame 9, avoiding the friction between the steel cable 6 and the cross beam 3, playing a role in reducing the winding resistance of the roller 5. When the mounting frame 801 drives the clamped and fixed brush roller to rise and hang above the ground, it is convenient for the operator to take out and replace the roller brush arranged on its surface from bottom to top. By fixedly connecting multiple trapezoidal blocks 12 between the outer surfaces of both sides of the support frame 2 and the top of the bottom plate 1, it plays a role in strengthening the strength of the support frame 2. By respectively fixedly connecting reinforcing blocks 11 between the cross beam 3 and the outer surfaces of both sides of the support frame 2, it plays a role in increasing the support for the cross beam 3, improving the overall stability of the device during operation.
