Detailed Implementation

[0032] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 5 As shown, the handcart of this utility model is designed for the bearing housing of a slurry pump. The bearing housing connects the motor and the driven component, and is used for transmission. The bearing housing contains bearings to ensure that the protruding shafts at both ends can rotate smoothly. It is mainly responsible for bearing loads from the axial and radial directions, ensuring the stability and reliability of the machinery during operation.

[0034] like Figures 1 to 5 As shown, a trolley for transporting bearing housings of a slurry pump is disclosed. The bearing housing includes a cylindrical body 1 and a raised mounting block 2. Connecting shafts 3 are respectively connected to both ends of the cylindrical body 1 along its length. The raised mounting block 2 is fixedly installed on the circumference of the cylindrical body 1. The trolley includes a frame 4 and casters 5. The casters 5 are installed on the bottom surface of the frame 4. A brake pedal is provided on the caster 5. Stepping on the brake pedal can activate the braking function, and stepping on the brake pedal again can release the brake. In this embodiment, the number of casters 5 is preferably four, and the four casters 5 are distributed at the four corners of the frame 4. A base plate 6 is provided on the top surface of the frame 4. A bracket 7 and two bearing seats 8 are provided on the base plate 6. The two bearing seats 8 are arranged along the length of the cylindrical body 1. The two bearing seats 8 with a gap can support the horizontally placed cylindrical body 1. The bearing seats 8 can stably support the horizontally placed cylindrical body 1. The bracket 7 is located outside between the two bearing seats 8. The bracket 7 can be engaged with the raised mounting block 2, which further enhances the stability and reliability of the bearing and avoids the equipment from sliding or tipping over during transportation.

[0035] The mounting bracket 7 includes two mounting plates 9, which are fixedly mounted on the base plate 6. A protruding mounting block 2 can be engaged between the two mounting plates 9. By restricting the protruding mounting block 2 between the two mounting plates 9, the bearing housing is prevented from moving in the longitudinal direction, thus preventing it from moving back and forth and ensuring that the bearing housing is not easily slipped or tipped over on the handcart.

[0036] The upper side of the clamping plate 9 has a through hole. The clamping seat 7 also includes a clamping bolt 10 and a clamping nut 11. The clamping bolt 10 can pass through both through holes simultaneously and be threadedly connected to the clamping nut 11. The outer end of the protruding mounting block 2 is clamped below the clamping bolt 10. The clamping nut 11 is located on the outside of the clamping plate 9. The clamping bolt 10 restricts the protruding mounting block 2 between the two clamping plates 9 so that the bearing housing as a whole will not rotate upward, thereby stabilizing the bearing housing on the handcart.

[0037] The support base 8 includes a semi-circular bracket 12 and two first fixed ears 13. The semi-circular bracket 12 with its opening facing upward is fixedly connected to the base plate 6. A reinforcing rib 21 is also connected between the semi-circular bracket 12 and the base plate 6. The two first fixed ears 13 are fixedly connected to both ends of the semi-circular bracket 12. The handcart also includes a fastening base 14, a fastening bolt 15, and a fastening nut 16. The fastening base 14 includes a semi-circular fastening frame 17 and two second fixed ears 18. The two first fixed ears 13 are fixedly connected to both ends of the semi-circular fastening frame 17. The semi-circular fastening frame 17 with its opening facing downward can abut against the corresponding semi-circular bracket 12. The fastening bolt 15 passes through both the first fixed ears 13 and the second fixed ears 18. The end of the fastening bolt 15 is threadedly connected to the fastening nut 16. The fastening nut 16 is below the first fixed ears 13. The cylindrical body 1 of the bearing housing is securely positioned between the semi-circular bracket 12 and the semi-circular fastening frame 17 to ensure that the cylindrical body 1 does not jump up and down, reduce vertical vibration, ensure stability during transportation, and protect the bearing housing and its internal precision components from damage.

[0038] The handcart also includes a shock-absorbing device 19, which is disposed between the base plate 6 and the frame 4. The shock-absorbing device 19 includes multiple shock-absorbing springs 20 and multiple telescopic components. The telescopic components are fixedly connected between the base plate 6 and the frame 4, and the shock-absorbing springs 20 are fixedly connected between the base plate 6 and the frame 4. One shock-absorbing spring 20 is sleeved on the outer periphery of one telescopic component. The telescopic component includes a round tube 22 and a round rod 23. The round rod 23 is inserted into the round tube 22 and slidably connected to the round tube 22. The round rod 23 does not detach from the round tube 22. The bottom surface of the round tube 22 is fixedly connected to the top surface of the frame 4, and the top surface of the round rod 23 is fixedly connected to the bottom surface of the base plate 6. The number of shock-absorbing springs 20 and telescopic components in this embodiment is not limited. The specific number is configured so that the shock-absorbing springs 20 can support the weight of all components on the base plate 6. Because the shock-absorbing device 19 includes multiple shock-absorbing springs 20 and telescopic components, it effectively absorbs vibrations when the handcart is carrying heavy objects or traversing uneven surfaces, reducing the risk of damage to the bearing housing and improving the overall stability of the handcart. The design of the shock-absorbing device 19, through its structural features (such as the sliding connection between the round tube 22 and the round rod 23), effectively buffers vibrations, protecting the bearing housing and its internal precision components from damage, thus improving the safety and service life of the bearing housing.

[0039] A rubber plate 24 is provided on the front side of the frame 4. Multiple buffer springs 25 are provided between the rubber plate 24 and the frame 4. They can play a buffering role in the event of an emergency. The rubber plate 24 and the buffer springs 25 prevent direct collision with other objects and protect the bearing box and its internal precision components from damage.

[0040] A handrail bracket 26 is fixedly connected to the upper rear of the frame 4, and a warning light 27 is installed on the handrail bracket 26. The warning light 27 can provide a clear visual cues during operation, reminding people around to pay attention and avoid the area, thus improving the safety of the operation. At the same time, it can also illuminate the way ahead for the operator pushing the cart at night.

[0041] The handcart has a simple design and is easy to operate. It can be put into use quickly without complicated preparation, which greatly shortens the transfer time and improves work efficiency.

[0042] When in use, the handcart will not move arbitrarily when the brake on the caster 5 is stepped on. The operator lifts the bearing box onto the semi-circular bracket 12, inserts the protruding mounting block 2 between the two clamping plates 9, and the clamping bolt 10 can pass through the two through holes at the same time. The end of the clamping bolt 10 is threadedly connected to the clamping nut 11. The semi-circular fastening bracket 17 is put on top of the cylindrical body 1, and then the fastening bolt 15 is passed from top to bottom through the second fixing ear 18 and the first fixing ear 13. The fastening nut 16 is screwed into the lower part of the fastening bolt 15 from bottom to top. The warning light 27 is turned on. The loading is complete. The brake on the caster 5 can be released to push the cart.

[0043] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
