Description

Technical Field

[0001] This utility model belongs to the field of conveyor vehicle manufacturing technology, and in particular relates to a raw material barrel conveyor vehicle that prevents tipping. Background Technology

[0002] In industrial production, the transportation of raw material barrels within the plant is generally accomplished using hand-pushed conveyor carts. Traditional conveyor carts often employ a simple frame structure secured with straps, resulting in significant stability defects.

[0003] In existing technologies, fixing devices mostly rely on single-point locking methods such as top pressure plates or side buckles, which leads to significant stress concentration and makes the locking mechanism prone to loosening under transportation vibration conditions. Especially when the loading height of the raw material drums exceeds 1.2 meters, the lateral moment generated by the inertia of the drums when the vehicle passes over the factory slopes or uneven road surfaces can easily exceed the bearing limit of the single fixing point, causing the drums to tip over.

[0004] Some improvement solutions attempt to use multi-point strap reinforcement, but this has revealed problems such as low adjustment efficiency and poor adaptability to different barrel diameters. Furthermore, the creep characteristics of the strap material cause the locking force to decrease over time. In addition, existing conveyor vehicles lack a three-dimensional constraint mechanism and cannot form an effective three-dimensional confinement space. When transporting irregularly shaped barrels or half-full liquid raw material barrels, the dynamic load generated by liquid sloshing will exacerbate the risk of barrel instability.

[0005] Therefore, there is an urgent need to develop an anti-tipping conveyor device with adaptive locking capability and three-dimensional mechanical constraint to solve the technical bottlenecks of traditional equipment, such as stress concentration, dynamic instability and insufficient adaptability to multiple specifications. Utility Model Content

[0006] The purpose of this invention is to provide a material barrel conveyor that prevents tipping over, in order to solve the problems of stress concentration, dynamic instability and insufficient adaptability to multiple specifications of traditional conveyor vehicles.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a frame, a truck bed, a wheel set, and a handlebar. A central upright is erected in the middle of the truck bed, and a square grid frame is provided on the outside of the central upright. A locking mechanism is provided at the top of the square grid frame. The locking mechanism includes a mounting disc that is penetrated through the center of the central upright, a threaded rod, and a lock provided on the inner side of the mounting disc. The mounting disc includes two semi-circular mounting sub-discs.

[0008] Furthermore, the lock includes a pair of internal threaded rings and support plates on both sides of the internal threaded rings, with a connecting rod between the internal threaded rings and the support plates.

[0009] Furthermore, U-shaped connectors are fixedly provided on both sides of the outer surface of the internal threaded ring, the cross-section of the support plate is C-shaped, the connecting rod is connected to the U-shaped connectors and the two side walls of the C-shaped support plate through a rotating shaft, and several anti-slip convex strips are fixedly provided on the outer surface of the support plate.

[0010] Furthermore, a pair of internally threaded rings are sleeved on the outside of the threaded rod. The top of the internally threaded rings is provided with a sliding groove, and a sliding rail is provided in the sliding groove. The two ends of the sliding rail are respectively connected to the two mounting sub-plates by screws.

[0011] Furthermore, one end of the threaded rod is inserted into one of the mounting sub-discs and connected to it via a rotating shaft, and the other end of the threaded rod passes through another mounting sub-disc and is connected to it via a rotating shaft. A connecting block is fixedly provided at the end of the threaded rod, and an insertion hole is provided in the connecting block.

[0012] Furthermore, vertical grooves are vertically formed on both sides of the central upright, and the threaded rod slides within the vertical grooves.

[0013] Furthermore, the central upright is connected to the truck bed by screws, the grid frame is connected to the mounting disc by screws, and the two mounting sub-discs are connected by screws.

[0014] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0015] 1. In this utility model, the bidirectional synchronous telescopic control of the support plate is achieved through the cooperative design of the positive and negative threads of the threaded rod and the internal threaded ring. When the threaded rod rotates, the two reverse threads drive the internal threaded ring to move precisely along the slide rail, thereby driving the C-shaped support plate to complete the radial expansion action. This linkage mechanism makes the locking force evenly distributed on the inner wall of the central upright, effectively avoiding the stress concentration problem caused by traditional single-point locking. Combined with the friction enhancement design of the anti-slip convex strip, the radial constraint stability of the lock is significantly improved, preventing locking failure caused by vibration during transportation.

[0016] 2. In this utility model, a three-dimensional constraint structure combining a central upright and a grid frame is adopted. Through the synergistic effect of the top grid coverage and the central vertical support, a three-dimensional confinement space is formed. The grid frame can be adjusted along the central upright according to the height of the raw material barrels. Its grid structure can adapt to different barrel diameters and can also achieve parallel fixing of multiple barrels. Combined with the rigid support system formed by the locking devices, it effectively disperses the inertial load during transportation, reduces the risk of barrel tipping over, and is particularly suitable for material transportation in factory environments with varying elevations.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Combination Figures 1 to 3 The illustrated material barrel conveyor includes a frame, a truck bed 1, a wheel set, and a handlebar. A central upright 2 is erected in the middle of the truck bed 1, and a grid frame 3 is provided on the outer side of the central upright 2. A locking mechanism 4 is provided on the top of the grid frame 3. The locking mechanism 4 includes a mounting disc 41 that is penetrated through the central part of the central upright 2, a threaded rod 42, and a lock 43 located inside the mounting disc 41. The mounting disc 41 includes two semi-circular mounting sub-discs 411. The interior of the central upright 2 is hollow. The lock 43 is located in the interior space of the central upright 2, and the mounting disc 41 slides on the outer wall of the central upright 2. The surface of the threaded rod 42 is provided with two sections of threads in opposite directions. The two semi-circular mounting sub-discs 411 are spliced ​​together and connected by screws.

[0025] The lock 43 includes a pair of internal threaded rings 431 and support plates 432 on both sides of the internal threaded rings 431. A connecting rod 433 is provided between the internal threaded rings 431 and the support plates 432. The threads on the inner side of the two internal threaded rings 431 are in the same direction as the threads at the corresponding positions on the threaded rod 42. When the threaded rod 42 rotates, the two internal threaded rings 431 move towards the center or away from the sides in sync.

[0026] Both sides of the outer surface of the internal threaded ring 431 are fixed with U-shaped connectors 434. The cross-section of the support plate 432 is C-shaped. The connecting rod 433 is connected to the U-shaped connectors 434 and the two side walls of the C-shaped support plate 432 through a rotating shaft. Several anti-slip convex strips 435 are fixed on the outer surface of the support plate 432. When the two internal threaded rings 431 move towards the middle, they are linked with the connecting rod 433 to push the support plates 432 on both sides outward until they fit against the inner side wall of the central upright 2 and are squeezed outward to form a locking effect.

[0027] A pair of internal threaded rings 431 are fitted on the outside of the threaded rod 42. The top of the internal threaded rings 431 is provided with a sliding groove 436. A slide rail 437 is provided in the sliding groove 436. The two ends of the slide rail 437 are respectively connected to two mounting sub-plates 411 by screws. The slide rail 437 restricts the movement direction of the two internal threaded rings 431 to prevent axial overturning.

[0028] One end of the threaded rod 42 is inserted into one of the mounting sub-discs 411 and connected to it via a rotating shaft. The other end of the threaded rod 42 passes through another mounting sub-disc 411 and is connected to it via a rotating shaft. A connecting block 421 is fixedly provided at the end of the threaded rod 42. An insertion hole 422 is provided in the connecting block 421. The insertion hole 422 is used to insert the output end of the ratchet wrench.

[0029] Vertical grooves 21 are vertically opened on both sides of the central upright 2, and the threaded rod 42 slides in the vertical grooves 21.

[0030] The central upright 2 is connected to the truck bed 1 by screws, the square frame 3 is connected to the mounting disc 41 by screws, and the two mounting sub-discs 411 are connected by screws.

[0031] Working principle: In use, the raw material barrel is placed in the truck bed 1, and the position of the grid frame 3 is adjusted according to the height of the barrel along the slide groove 436 of the central upright 2. A tool is inserted into the insertion hole 422 of the connecting block 421 at the end of the threaded rod 42, and the threaded rod 42 is rotated. Since the two ends of the threaded rod 42 are connected to two mounting sub-plates 411 through rotating shafts respectively, and the rod body has positive and negative threaded sections, the rotation drives the two internal threaded rings 431 sleeved on it to slide in opposite directions along the slide rail 437. The movement of the internal threaded rings 431 is transmitted to the C-shaped support plate 432 through the U-shaped connector 434 and the connecting rod 433, so that the support plate 432 unfolds outward around the rotation axis. The anti-slip ridges 435 on the outer surface of the support plate 432 are in close contact with the inner wall of the raw material barrel, which enhances the locking effect through friction and forms a uniform radial constraint force to avoid stress concentration at a single point. The grid of the square frame 3 covers the top of the barrel, the central upright 2 provides vertical support, and the support plate 432 of the lock 43 applies radial clamping force. The three work together to form a three-dimensional limiting space. During transportation, the inertial load is distributed to the vehicle frame through the square frame 3 and the central upright 2, which significantly reduces the risk of the barrel tipping over.
