Abstract
Description
Technical Field
[0001] This utility model relates to a maintenance cart, and more particularly to a biomass burner maintenance cart. Background Technology
[0002] A biomass burner is a device that uses biomass pellets as fuel to provide energy through combustion.
[0003] During use, biomass burners generally require routine maintenance, including the burner's feed hopper and shell. Maintenance requires disassembly and transportation using a trolley. Currently, the trolleys used for burner maintenance typically include a liftable support platform. However, since the burner's feed hopper and shell are irregularly shaped, and at least half of the shell extends beyond the support platform and is suspended in the air, existing trolleys do not have adequate stabilizing limits, which can easily cause shaking or even falling during transport.
[0004] It should be noted that the above content falls within the scope of the technical knowledge of the utility model owner and does not necessarily constitute prior art. Utility Model Content
[0005] To solve the above problems, the purpose of this utility model is to provide a biomass burner maintenance trolley, including a base frame, universal wheels fixedly provided at the four corners of the bottom of the base frame, a push handle fixedly provided on one side of the top of the base frame, and a support frame provided on the top of the base frame;
[0006] A scissor lift is movably installed between the base frame and the support frame, and the scissor lift is driven by a screw and a handwheel.
[0007] A limiting frame is fixedly provided on one side of the support frame, a fixing rod is fixedly provided on one side of the top of the limiting frame, a threaded rod is threadedly connected to one side of the fixing rod, a pressure plate is fixedly provided at the bottom of the threaded rod, an adjusting wheel is fixedly provided at the top of the threaded rod, two support plates are fixedly provided on one side of the support frame through a connecting rod, and limiting baffles are fixedly provided on both sides of the top of the support frame.
[0008] In one example, a balance frame is fixedly provided on one side of the base frame, a sliding groove is provided on the top of the balance frame, and a sliding rod is provided between the two support plates, with the sliding rod slidably connected to the sliding groove.
[0009] In one example, the lead screw is inserted into the base frame, and the movable rod at the bottom of the scissor lift is sleeved on the outside of the lead screw.
[0010] In one example, one end of the lead screw passes through a connecting box provided on the inner wall of one side of the base frame and is fixedly connected to a handwheel.
[0011] In one example, the lead screw portion inside the connecting box has a fixing screw hole, and a fixing bolt is inserted through the top of the connecting box, and the lead screw is fixed by the fixing bolt.
[0012] The biomass burner maintenance cart proposed in this utility model can bring the following beneficial effects:
[0013] This utility model uses a threaded rod and pressure plate on one side of the support frame to stably press the shell onto one side of the burner housing. At the same time, a support plate is set on a part of the support frame, which is supported by a balance frame to stably support the suspended part of the maintenance shell that exceeds the support area. Then, a limiting baffle limits both sides of the maintenance shell, thereby achieving a stable limiting effect on the shell and preventing shaking or even falling during the pushing process.

[0020] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0021] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] like Figures 1-4 As shown, an embodiment of this utility model proposes a biomass burner maintenance trolley, including a base frame 1, universal wheels 1 fixedly installed at the four corners of the bottom of the base frame 1, a push handle 3 fixedly installed on one side of the top of the base frame 1, a support frame 4 installed above the base frame 1, and a scissor lift frame 5 movably installed between the base frame 1 and the support frame 4. The scissor lift frame 5 is driven by a screw 6 and a handwheel 7.
[0023] A limiting frame 9 is fixedly provided on one side of the support frame 4. A fixing rod 10 is fixedly provided on one side of the top of the limiting frame 9. A threaded rod 11 is threadedly connected to one side of the fixing rod 10. A pressure plate 13 is fixedly provided at the bottom of the threaded rod 11. An adjusting wheel 12 is fixedly provided at the top of the threaded rod 11. Two support plates 16 are fixedly provided on one side of the support frame 4 through a connecting rod 15. Limiting baffles 14 are fixedly provided on both sides of the top of the support frame 4.
[0024] A balance frame 17 is fixedly installed on one side of the base frame 1. A sliding groove is provided on the top of the balance frame 17. A sliding rod is provided between the two support plates 16, and the sliding rod is slidably connected to the sliding groove.
[0025] The lead screw 6 is inserted into the base frame 1, and the moving rod at the bottom of the scissor lift frame 5 is sleeved on the outside of the lead screw 6. One end of the lead screw 6 passes through the connecting box 8 provided on the inner wall of one side of the base frame 1 and is fixedly connected to a handwheel 7. The lead screw 6 part placed inside the connecting box 8 has a fixing screw hole, and a fixing bolt 18 is inserted through the top of the connecting box 8. The lead screw 6 is fixed by the fixing bolt 18.
[0026] Working principle: When in use, place the disassembled burner shell (hopper, etc.) on the support frame 4. After being limited by the limit baffles 14 on both sides, rotate the adjusting wheel 12. The threaded rod 11 and the pressure plate 13 descend, so that the pressure plate 13 is stably pressed on one side of the burner shell. At this time, the support plate 16 provides stable support for the suspended part of the shell that exceeds the bearing area. The balance frame 17 is set on one side of the base frame to support the support plate 16, prevent the center of gravity from shifting, and facilitate pushing and transporting. After the support is stable, unscrew the fixing bolt 18, rotate the handwheel 7 and the lead screw 6. The lead screw 6 converts the rotary motion into linear motion, which drives the moving rod of the scissor lift frame 5 to move, so that the support frame 4 rises. After rising to the specified height, tighten the fixing bolt 18 to fix the lead screw 6.
