Description

Technical Field

[0001] The utility model belongs to the technical field of cotton bale transportation, in particular to a cotton bale lifting and transportation vehicle. Background Art

[0002] Cotton bale transporters are suitable for transporting individual cotton bales at cotton processing and spinning companies, which form a supply chain relationship between upstream and downstream enterprises. Type I cotton bales, a common product at Chinese cotton processing companies, have basic dimensions of 1400mm × 530mm × 700mm. The two surfaces at the 700mm mark are compressed and arc-shaped, while the other four surfaces are regular. They weigh 227±10kg. Imported cotton bales also have this basic size and weight.

[0003] Currently, cotton bale transportation at cotton processing companies is divided into two areas: the workshop and the freight yard. Cotton bales are compressed and formed by hydraulic cotton baling presses in the workshop. When they leave the box, the bales undergo a 90-degree flip, with the two surfaces 530 mm apart forming upper and lower planes. After being transported out of the workshop on a belt conveyor, forklifts equipped with horizontal telescopic cylinder bale clamps act on the curved or side surfaces of the bales, stacking them four layers high. Two stacks, totaling eight bales, are arranged side by side to form a group. A forklift then clamps the bales and transports them to the freight yard. A few cotton processing companies were established earlier, and the cramped space outside their workshops, made inconvenient for forklifts, forced them to use wire rope electric hoists with articulated clamps to move individual bales to a more accessible location for forklifts, adding a bale transfer step (process). Articulated clamps are generally homemade, and their working principle is similar to the grab bucket of a port crane for grabbing bulk cargo. Workers assist in lowering the articulated clamps to the outside of the two curved surfaces or side planes of the cotton bale. When the wire rope electric hoist lifts the bale, the articulated clamps shrink horizontally to clamp the cotton bale. Then workers operate the wire rope electric hoist to lift, transfer and unload the cotton bale. There is a risk of the cotton bale slipping from the articulated clamps during transportation.

[0004] After a forklift transports a group of eight cotton bales to the cotton processing company's freight yard, it unloads the bales onto a pier-like foundation laid on the ground. After a period of storage, the bales are loaded onto a flatbed truck using a forklift. The forklift picks up a maximum of eight bales and places them onto the truck. Each truck loads a batch of 186 bales, weighing approximately 42,000 kg. Once loaded, the flatbed truck departs the cotton processing company for transport to a railway freight yard, cotton storage warehouse, or cotton spinning company warehouse, where it is again unloaded using a forklift.

[0005] Therefore, it is necessary to provide a cotton bale transporter that is suitable for transporting single cotton bales in cotton processing enterprises or cotton spinning enterprises, and for transporting cotton bales when the space is narrow and the operating range of the forklift is insufficient. It is especially suitable for crossing areas where other equipment or personnel cannot pass. Summary of the Invention

[0006] The purpose of the utility model is to provide a cotton bale lifting transport vehicle to address the deficiencies of the above-mentioned prior art, so as to realize the aerial transportation of cotton bales stably and avoid slipping.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A cotton bale lifting vehicle comprises a track frame, a driving device arranged on the track frame, and a vehicle hoisted below the driving device, wherein the vehicle reciprocates along the track on the track frame under the action of the driving device;

[0009] Two lifting plate shafts are symmetrically provided on the lower frame of the transport vehicle, and lifting plates are installed at both ends of each lifting plate shaft, and the lifting plates are in an arc-shaped structure. The lifting plates on the two lifting plate shafts are symmetrically arranged, and the arc-shaped surface structures are arched inward to form a cotton bale transport cavity on the inside;

[0010] Auxiliary turning devices are provided on the two lifting plate shafts to control their forward and reverse turning.

[0011] The auxiliary turning device includes a driving motor provided in the middle of the transport vehicle, a driving shaft and a first driven shaft connected thereto, wherein one end of the driving shaft is driven to the first driven shaft via a chain, and the other end of the driving shaft is driven to the second driven shaft via gear meshing;

[0012] The first driven shaft and the lifting plate shaft on the same side are driven by a chain, and the second driven shaft and the other lifting plate shaft on the same side are driven by a chain.

[0013] When the driving motor rotates forward, the gear meshing transmission and chain transmission drive the lifting plates on both sides to turn inward synchronously to lift the cotton bales;

[0014] When the driving motor rotates in reverse, the lifting plate flips outward synchronously to loosen and unload the cotton bale.

[0015] The upper part of the transport vehicle is provided with symmetrically arranged rail wheels, which are respectively installed at both ends of the vehicle body drive shaft and the vehicle body driven shaft, and the driving device transmits power to the vehicle body drive shaft through chain transmission to drive the transport vehicle forward and backward.

[0016] The lifting plate is provided with a threaded hole and is fixedly connected to a clamp surrounding the lifting plate axis by means of screws.

[0017] A reinforcing rib plate is also fixedly provided on the inner side of the lifting plate.

[0018] Four columns are provided at the lower end of the track frame, and base plates of the columns are fixed to the ground by anchor bolts or welded to embedded parts under the ground.

[0019] The beneficial effects of the utility model are:

[0020] (1) The cotton bale lifting transport vehicle is constructed by symmetrically arranging two lifting plate shafts on the lower frame of the transport vehicle, and lifting plates are installed at both ends of each lifting plate shaft, and the lifting plates are in an arc-shaped structure. The lifting plates on the two lifting plate shafts are symmetrically arranged, and the arc-shaped structures are all arched inward, forming a cotton bale transport cavity on the inner side; and auxiliary turning devices are provided on the two lifting plate shafts to control their forward and reverse turning. The lifting plates are in an outward-bulging arc-shaped surface, which forms a pure rolling with the arc-shaped surface of the cotton bale, which can ensure that they are tightly fitted with the cotton bale and do not slip, and can also reduce the friction damage to the outer packaging material of the cotton bale during movement. The cotton bale can be grabbed and clamped by the lifting cotton bale transport vehicle installed on the elevated track, and the cotton bale can be smoothly transported in the air and unloaded after arriving at the destination.

[0021] (2) Aerial transportation is achieved by using a transport vehicle installed on an elevated track, which reduces the labor intensity of workers and automatically completes operations that originally required the assistance of workers. It is also suitable for the front and rear connection needs between two types of cotton bale transportation equipment. The wedge effect formed between the curved surface of the lifting plate and the curved surface of the cotton bale is used to steadily hold the cotton bale to ensure that the cotton bale will not slip.

[0026] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0027] The utility model provides a cotton bale lifting and transporting vehicle. Figures 1 to 4 shown.

[0028] A cotton bale lifting transport vehicle comprises a track frame, a driving device arranged on the track frame and a transport vehicle 2 hoisted below the driving device, and the transport vehicle 2 reciprocates along the track 9 on the track frame under the action of the driving device; two lifting plate shafts 5 are symmetrically provided on the lower frame of the transport vehicle 2, and each lifting plate shaft 5 is installed with a lifting plate 6 at both ends, and the lifting plate 6 has an arc-shaped surface structure, and the lifting plates 6 on the two lifting plate shafts 5 are symmetrically arranged, and the arc-shaped surface structures are all arched inward and form a cotton bale transport cavity on the inner side; and the two lifting plate shafts 5 are provided with auxiliary flipping devices to control their forward and reverse flipping.

[0029] The auxiliary turning device includes a driving motor provided in the middle of the transport vehicle 2 and a driving shaft 15 and a first driven shaft 12 connected to the driving motor. In this embodiment, the driving motor adopts a worm gear reducer 11; one end of the driving shaft 15 is transmitted to the first driven shaft 12 through a chain, and the other end of the driving shaft 15 is transmitted to the second driven shaft 16 through gear meshing; the first driven shaft 12 and a lifting plate shaft are powered by a chain drive, and the second driven shaft 16 and another lifting plate shaft are powered by a chain drive; when the driving motor rotates forward, the lifting plates 6 on both sides are synchronously turned inward through gear meshing transmission and chain transmission to lift the cotton bale 1; when the driving motor rotates reversely, the lifting plates 6 are synchronously turned outward to loosen and remove the cotton bale 1.

[0030] The upper part of the transport vehicle 2 is provided with symmetrically arranged rail wheels 14 and respectively installed at both ends of the vehicle body drive shaft 17 and the vehicle body driven shaft 10, and the driving device transmits power to the vehicle body drive shaft 17 through a chain drive to drive the transport vehicle 2 forward and backward.

[0031] The lifting plate 6 is provided with a threaded hole and is fixedly connected with a hoop 7 around the lifting plate shaft 5 by arranging screws. In order to improve the lifting plate 6 intensity, a reinforcing rib plate is also fixedly provided on the lifting plate 6 inner side.

[0032] Four columns 8 are provided at the lower end of the track frame, and base plates of the columns 8 are fixed to the ground by anchor bolts or welded to embedded parts under the ground.

[0033] More specifically, a cotton bale 1 is an item to be transported from location A to location B. Cotton bale 1 is typically wrapped with eight straps and is approximately rectangular in shape. Due to compression molding on the cotton processing line, four of its surfaces are flat, while the other two surfaces are curved due to the elastic force of the compressed cotton. The cotton bale transport vehicle utilizes four lifting plates 6 acting on the two curved surfaces of the cotton bale 1, creating a wedge effect that steadily holds the cotton bale 1. The transport vehicle 2 runs along the track 9 on the track frame to location B and unloads the cotton bale 1.

[0034] In this embodiment, there are two rails 9, each supported by two columns 8. The base plates of the columns 8 are fixed to the ground by anchor bolts or welded to embedded parts under the ground to form a stable rail frame.

[0035] There are four rail wheels 14 on the upper part of the transport vehicle 2, which are located on the track 9 and installed at both ends of the vehicle body drive shaft 17 and the vehicle body driven shaft 10. The reducer 18 of the driving device transmits the power to the sprocket 21 at the end of the vehicle body drive shaft 17 through the sprocket 19 and the roller chain 20, and implements the forward and backward movement of the transport vehicle 2 to complete the process of transporting the cotton bale 1 from A to B.

[0036] The drive motor, or worm gear reducer 11, in the center of the transporter 2 transmits power to the first driven shaft 12 via the sprocket 4 and roller chain 13 at the end of the drive shaft 15. This power is then transmitted to the second driven shaft 16 through the meshing gear 22 at the other end of the drive shaft 15. The first and second driven shafts 12 and 16 transmit power to the lifting plate shafts 5 at the bottom of the transporter 2 via the sprockets 4 and roller chains 3 at their respective other ends. Lifting plates 6 are secured to the lifting plate shafts 5 at the bottom of the transporter 2 via the clamps 7 on the lifting plate shafts 5 via screws. Two lifting plates 6 are mounted on each of the two lifting plate shafts 5. The four lifting plates 6 are distributed below the two curved surfaces of the cotton bale 1. These lifting plates 6 also have an outwardly bulging curved surface, forming a pure rolling motion with the curved surface of the cotton bale 1. This ensures a tight fit with the cotton bale 1 and prevents slippage, while also reducing frictional damage to the outer packaging material of the cotton bale 1 during movement. When the worm gear reducer 11 rotates, the four lifting plates 6 are synchronously flipped inward through gear meshing transmission and chain transmission, thereby lifting the cotton bale 1; after the transport vehicle 2 moves from point A to point B, the worm gear reducer 11 is reversed, and the four lifting plates 6 are synchronously flipped outward, thereby loosening and unloading the cotton bale 1.
