Description

Technical Field

[0001] This utility model relates to the field of mechanical vehicle technology, specifically a mechanical vehicle with a rapid movement function. Background Technology

[0002] Mechanical carts are widely used as an important transportation and operation tool in laboratory material transportation. In laboratory warehouses, mechanical carts are used for sorting and storing goods, and quickly and efficiently complete the transfer of goods.

[0003] Existing mechanical vehicles are insufficient to meet the demands for rapid response in practical applications. Current common mechanical vehicle braking systems rely on manual operation of complex mechanical structures to gradually release braking force and separate the brake pads from the brake drum. This is not only cumbersome, but also results in slow brake pad disengagement from the brake drum due to friction and transmission delays between mechanical components. Consequently, the wheels cannot immediately resume rotation, preventing the vehicle from quickly entering a moving state. Therefore, a mechanical vehicle with rapid movement capability is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical vehicle with a fast-moving function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical trolley with a rapid movement function, comprising a trolley body, a fixed frame fixed to the rear bottom of the trolley body, a rotating shaft rotatably connected to the fixed frame via a bearing, and a wheel fixed to one end of the rotating shaft;

[0006] A brake assembly is provided on one side of the wheel, and a placement assembly is provided on the top of the brake assembly;

[0007] The placement assembly includes two connecting frames, a connecting rod is fixed to the inner wall of the connecting frame, a limiting frame is provided on the inner side of the connecting frame, an oblong hole is opened on one side of the limiting frame, and a horizontal plate is fixed to the top of the limiting frame.

[0008] The brake assembly includes a support rod, a slide post is inserted into one side of the support rod, a slide plate is fixed to the bottom of the slide post, a push rod is fixed to the bottom of the slide plate, and a brake pad is fixed to the bottom of the push rod.

[0009] Preferably, the connecting rod is inserted into the inner side of the waist-shaped hole, and when the limiting frame is in a horizontal state, the top of the horizontal plate is used to place items.

[0010] Preferably, as described above, two support frames are fixed to the rear side of the top of the vehicle body, and omnidirectional wheels are fixed to the front side of the bottom of the vehicle body.

[0011] Preferably, the connecting frame is fixed to one side of the support frame, and a first guardrail is fixed to the top of the cross plate.

[0012] Preferably, as described above, a brake drum is fixedly sleeved on the outer side of the rotating shaft. When the brake pads are in contact with the outer side of the brake drum, the vehicle body is in a stopped state. When the brake pads are away from the outer side of the brake drum, the vehicle body is in a moving state.

[0013] Preferably, as described above, the top of the sliding column is connected to a pressure plate by bolts, and a spring is sleeved on the outside of the sliding column, with the two ends of the spring connected to one side of the pressure plate and the support rod, respectively.

[0014] Preferably, the slide plate is slidably connected to the inner wall of the support frame, and the support rod is fixed to the top of the support frame.

[0015] Preferably, the bottom of the vehicle body is bolted with a protective cover located outside the brake pads and brake drum, and the top of the vehicle body is fixed with a second guardrail.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0017] 1. When small items are not needed, the limiting frame, horizontal plate, and first guardrail can be adjusted to a vertical position, effectively saving space. When the limiting frame is in a horizontal position, items can be placed on the top of the horizontal plate. By simply pulling the horizontal plate upward, the connecting rod can slide in the waist-shaped hole and the limiting frame can be rotated to change the placement state. It can be flexibly adjusted according to the placement needs of different items, enhancing the practicality of the device.

[0018] Second, when the brake is released, the pressure plate drives the relevant components to move, which can quickly disengage the brake pads from the brake drum, allowing the wheels to rotate immediately and the vehicle to move quickly. When the vehicle stops, the spring's return force quickly pushes the slide and other components back into place, allowing the brake pads to quickly re-adhere to the surface of the brake drum, stopping the wheels from rotating in time. The fast response speed ensures the timeliness of vehicle movement and stopping, greatly improving the convenience and efficiency of operation, and meeting the actual needs of rapid vehicle movement and stopping.

[0029] Example

[0030] Please see Figure 1-6This utility model provides a technical solution: a mechanical trolley with a rapid movement function, including a trolley body 1. When transporting items inside a laboratory, the trolley body 1 can be moved quickly by simply placing the items on top of the trolley body 1 and pressing the pressure plate 55. This embodiment is suitable for light-load transportation in the laboratory. A fixed frame 10 is fixed to the rear bottom of the trolley body 1. The fixed frame 10 is rotatably connected to a rotating shaft 9 via a bearing. A wheel 7 is fixed to one end of the rotating shaft 9. A brake assembly 5 is provided on one side of the wheel 7. A placement assembly 2 is provided on the top of the brake assembly 5. Two support frames 6 are fixed to the rear top of the trolley body 1. The inner wall of the support frames 6 is coated with lubricating oil. A universal wheel 8 is fixed to the front bottom of the trolley body 1.

[0031] The placement component 2 includes two connecting frames 24. A connecting rod 26 is fixed to the inner wall of the connecting frame 24. A limiting frame 22 is provided on the inner side of the connecting frame 24. The limiting frame 22 and the connecting frame 24 are made of metal. A waist-shaped hole 25 is opened on one side of the limiting frame 22. A horizontal plate 21 is fixed to the top of the limiting frame 22. The width of the horizontal plate 21 is smaller than the width of the second guardrail 3. When the limiting frame 22 is horizontal, the horizontal plate 21 at its top and the first guardrail 23 form a placement platform. Pulling the horizontal plate 21 upwards causes the connecting rod 26 to slide along the waist-shaped hole 25 to the other end. Then, the limiting frame 22 is rotated to a vertical position to reduce the space occupied.

[0032] The connecting rod 26 is inserted into the inner side of the oblong hole 25. When the limiting frame 22 is in a horizontal state, the top of the horizontal plate 21 is used to place items. At this time, the connecting rod 26 is located on the top side of the inner wall of the oblong hole (e.g., Figure 6 Meanwhile, the bottom side of the limiting frame 22 abuts against the side of the support frame 6, and the height of the connecting rod 26 is higher than the contact position between the limiting frame 22 and the support frame 6, so that the limiting frame 22 is in a stable state, and there is a certain gap between the limiting frame 22 and the support frame 6. When the limiting frame 22 is pulled upward and rotated, interference between the limiting frame 22 and the support frame 6 is prevented.

[0033] When small items are not needed, simply pull the horizontal plate 21 upwards to allow the connecting rod 26 to slide from one side of the inner wall of the waist-shaped hole 25 to the other side. Then rotate the limiting frame 22 so that the limiting frame 22, the horizontal plate 21 and the first guardrail 23 are in a vertical state. The connecting frame 24 is fixed to one side of the support frame 6, and the first guardrail 23 is fixed to the top of the horizontal plate 21.

[0034] The brake assembly 5 includes a support rod 57, with a slide column 53 inserted into one side of the support rod 57. A slide plate 56 is fixed to the bottom of the slide column 53, and a push rod 54 is fixed to the bottom of the slide plate 56. A brake pad 51 is fixed to the bottom of the push rod 54. The elastic force of the spring 58 pushes the pressure plate 55 upward, causing the slide column 53 to drive the slide plate 56, push rod 54, and brake pad 51 to press tightly against the brake drum 52, locking the wheel 7 and keeping the vehicle body 1 stationary. The brake drum 52 is fixedly sleeved on the outside of the rotating shaft 9. When the brake pad 51 is in contact with the outside of the brake drum 52, the vehicle body 1 is in a stopped state. When the brake pad 51 leaves the outside of the brake drum 52, the vehicle body 1 is in a moving state. When rapid movement is not required, the elastic force of the spring 58 causes the brake pad 51 to adhere to the surface of the brake drum 52, preventing the vehicle body 1 from moving arbitrarily. Pressing the pressure plate 55 compresses the spring 58, causing the slide plate 56 to drive the push rod 54 and brake pad 51 downward, causing the brake pad 51 to leave the surface of the brake drum 52, thus allowing the vehicle body 1 to move quickly.

[0035] The top of the sliding column 53 is connected to the pressure plate 55 by bolts. The spring 58 can be replaced by removing the bolts connecting the pressure plate 55 and the sliding column 53. The spring 58 is sleeved on the outside of the sliding column 53. The two ends of the spring 58 are respectively connected to the pressure plate 55 and one side of the support rod 57. The sliding plate 56 is slidably connected to the inner wall of the support frame 6. The support rod 57 is fixed to the top of the support frame 6.

[0036] The bottom of the vehicle body 1 is fixed with a protective cover 4 located outside the brake pads 51 and brake drum 52 by bolts. The top of the vehicle body 1 is fixed with a second guardrail 3. The protective cover 4 protects the brake pads 51 and brake drum 52 and prevents them from being interfered with or damaged by external factors. The brake pads 51 and brake drum 52 can be maintained by removing the protective cover 4. The second guardrail 3 prevents items placed on the vehicle body 1 from falling.

[0037] Working principle: A rotating shaft 9 is rotatably connected to the rear bottom of the vehicle body 1 via a fixed frame 10 and a bearing. A wheel 7 is fixed to one end of the rotating shaft 9, and a caster wheel 8 is fixed to the front bottom of the vehicle body 1. The vehicle body 1 moves by the cooperation of the wheel 7 and the caster wheel 8. When transporting items inside the laboratory, place the items on top of the vehicle body 1 and press the pressure plate 55 with your hand to quickly move the vehicle body 1.

[0038] When the limiting frame 22 is in a horizontal state, the top of the horizontal plate 21 is used to place items. When small items are not needed, simply pull the horizontal plate 21 upwards so that the connecting rod 26 slides from one side of the inner wall of the waist-shaped hole 25 to the other side of the inner wall. Then rotate the limiting frame 22 so that the limiting frame 22, the horizontal plate 21 and the first guardrail 23 are in a vertical state to save space or adapt to different item placement needs.

[0039] When it is necessary to move the vehicle body 1, press down on the pressure plate 55 of the brake assembly 5 with your hand, and hold the support rod 57. The pressure plate 55 compresses the spring 58 through the sliding column 53, causing the sliding plate 56 to slide down along the inner wall of the support frame 6. The sliding plate 56 pushes the push rod 54 to disengage the brake pads 51 from the brake drum 52, releasing the braking state. After the brake is released, the wheels 7 rotate, enabling the vehicle body 1 to move quickly. At this time, the spring 58 is in a compressed and energy-storing state, and the brake pads 51 remain separated from the brake drum 52.

[0040] When it is necessary to stop, the pressure plate 55 is released, and the return force of the spring 58 pushes the slide column 53 to move upward, which drives the slide plate 56 and push rod 54 back to their original positions. The brake pad 51 re-adheres to the surface of the brake drum 52, and the wheel 7 stops rotating through friction.

[0041] In summary, when small items are not needed, the limiting frame 22, the horizontal plate 21, and the first guardrail 23 can be adjusted to a vertical position, effectively saving space. When the limiting frame 22 is in a horizontal position, items can be placed on the top of the horizontal plate 21. By simply pulling the horizontal plate 21 upwards, the connecting rod 26 can slide within the oblong hole 25 and the limiting frame 22 can be rotated, thus changing the placement state. This allows for flexible adjustment according to the placement needs of different items, enhancing the practicality of the device.

[0042] When the brake is released, the pressure plate 55 drives the relevant components to move, which can quickly disengage the brake pads 51 from the brake drum 52, allowing the wheels 7 to rotate immediately and the vehicle body 1 to move quickly. When the vehicle stops, the return force of the spring 58 quickly pushes the slide column 53 and other components back into place, allowing the brake pads 51 to quickly re-adhere to the surface of the brake drum 52, so that the wheels 7 can stop rotating in time. The fast response speed ensures the timeliness of the movement and stopping of the vehicle body 1, greatly improving the convenience and efficiency of operation, and meeting the actual needs of quickly moving and stopping the vehicle body 1.
