Description

Technical Field

[0001] The invention belongs to the technical field of cotton bale transport, and in particular relates to a cotton bale lifting and transporting vehicle. Background Art

[0002] Cotton bale transporter is suitable for occasions where cotton processing enterprises and cotton spinning enterprises need to transport single cotton bales. Cotton processing enterprises and cotton spinning enterprises are upstream and downstream of the supply chain. The basic dimensions of the Type I cotton bales commonly used by cotton processing enterprises in my country are 1400mm×530mm×700mm. The two surfaces in the 700mm direction are compressed surfaces in an arc shape, and the other four planes are regular planes. The weight is 227±10kg. Imported cotton bales also have this basic size and weight.

[0003] At present, cotton bales in cotton processing enterprises are transported in two areas: workshop and freight yard. Cotton bales are produced by compression molding of hydraulic cotton balers in the workshop. When the cotton bales are taken out of the bale box, they are turned 90 degrees. The two surfaces in the 530mm direction become the upper and lower planes. After being transported out of the workshop by belt conveyor, they are stacked up to 4 layers high by forklifts equipped with horizontal telescopic cylinder clamps, and two stacks of 8 cotton bales are arranged in parallel to form a combination. The forklifts clamp the cotton bales and transport them to the freight yard. A few cotton processing enterprises were established earlier, and there are other buildings outside the workshop, which makes the space narrow and inconvenient for forklift operation. They have to use wire rope electric hoists to hang articulated clamps to move single cotton bales to places convenient for forklift operation, which adds a cotton bale transfer link (process). The articulated clamp is usually homemade, and its working principle is the same as the grab bucket of a port crane for grabbing bulk cargo. Workers assist in lowering the articulated clamp to the outside of the two curved surfaces or side planes of the cotton bale. When the wire rope electric hoist lifts, the articulated clamp shrinks the clamp opening spacing horizontally to clamp the cotton bale. Then the 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 clamp during transportation.

[0004] After a forklift transports a cotton bale combination (8 bales) to the freight yard of the cotton processing enterprise, it unloads the bales onto the pier base laid on the ground. After the cotton bales are stored for a period of time, they will be loaded onto a flatbed truck by a forklift. The forklift will pick up at most 8 bales and put them on the flatbed truck. Each truck will load a batch of 186 bales, about 42,000 kg. After the flatbed truck is loaded with cotton bales, it will leave the cotton processing enterprise and be transported to the railway freight yard, cotton reserve warehouse or cotton spinning enterprise warehouse, where it will be unloaded by a forklift again.

[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 is suitable for transporting cotton bales when the space is narrow and the forklift operation range is insufficient, especially for areas where other equipment or personnel cannot pass. Summary of the invention

[0006] The object of the present invention is to provide a cotton bale lifting transport vehicle to address the above-mentioned deficiencies in the prior art, so as to stably transport the cotton bales in the air and avoid them from slipping.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: 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 a track on the track frame under the action of the driving device; Two lifting plate shafts are symmetrically arranged 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 surface structure, and the lifting plates on the two lifting plate shafts are symmetrically arranged, and the arc-shaped surface structures are arched inwards to form a cotton bale transport cavity on the inside; Auxiliary turning devices are arranged on the two lifting plate shafts to control the forward and reverse turning thereof.

[0008] The auxiliary turning device comprises a driving motor arranged in the middle of the transport vehicle, a driving shaft and a first driven shaft connected to the driving motor, one end of the driving shaft is driven to the first driven shaft through a chain, and the other end of the driving shaft is driven to the second driven shaft through gear meshing; 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. When the driving motor rotates forward, the lifting plates on both sides are driven to turn inward synchronously through gear meshing transmission and chain transmission to lift the cotton bale; When the driving motor rotates in reverse, the lifting plate flips outward synchronously to loosen and remove the cotton bale.

[0009] 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 driving shaft and the vehicle body driven shaft, and the driving device transmits power to the vehicle body driving shaft through chain transmission to drive the transport vehicle forward and backward.

[0010] 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.

[0011] A reinforcing rib plate is also fixedly provided on the inner side of the lifting plate.

[0012] Four columns are arranged 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.

[0013] The beneficial effects of the present invention are: (1) The cotton bale lifting and transporting vehicle comprises two lifting plate shafts symmetrically arranged on the lower frame of the transporting 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 inwardly, and a cotton bale transporting cavity is formed on the inner side; and auxiliary turning devices are provided on the two lifting plate shafts to control the forward and reverse turning of the lifting plates. The lifting plates have an outward-bulging arc-shaped surface, which forms a pure rolling with the arc-shaped surface of the cotton bale, which can not only ensure that the lifting plates are tightly fitted with the cotton bale to prevent slipping, but 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 and transporting vehicle installed on the elevated track, and the cotton bale can be smoothly transported in the air, and the cotton bale can be unloaded after arriving at the destination.

[0014] (2) Aerial transportation is achieved by installing a transport vehicle 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.

[0018] The present invention provides a cotton bale lifting vehicle, such as Figures 1 to 4 shown.

[0019] 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 arranged on the lower frame of the transport vehicle 2, and lifting plates 6 are installed at both ends of each lifting plate shaft 5, and the lifting plates 6 are in 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 inwardly to form a cotton bale transport cavity on the inner side; and auxiliary flipping devices are provided on the two lifting plate shafts 5 to control their forward and reverse flipping.

[0020] The auxiliary turning device includes a driving motor arranged 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 driven to the first driven shaft 12 through a chain transmission, and the other end of the driving shaft 15 is driven to the second driven shaft 16 through gear meshing; the first driven shaft 12 and a lifting plate shaft are driven by a chain transmission, and the second driven shaft 16 and another lifting plate shaft are driven by a chain transmission; when the driving motor rotates forward, the lifting plates 6 on both sides are driven to turn inward synchronously through gear meshing transmission and chain transmission to lift the cotton bale 1; when the driving motor is reversed, the lifting plates 6 are synchronously turned outward to loosen and remove the cotton bale 1.

[0021] The upper part of the transport vehicle 2 is provided with symmetrically arranged rail wheels 14 which are 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 chain transmission to drive the transport vehicle 2 forward and backward.

[0022] 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 strength of the lifting plate 6, a reinforcing rib plate is also fixedly arranged on the inner side of the lifting plate 6.

[0023] 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.

[0024] More specifically, the cotton bale 1 is a transported item that needs to be transported from location A to location B. The cotton bale 1 is generally covered with eight strapping bands and is approximately rectangular in shape. Due to compression molding on the production line of a cotton processing enterprise, four of its faces are regular planes, and the other two faces are curved faces with an outward drum shape due to the resilience of the cotton after compression. The cotton bale lifting vehicle uses four lifting plates 6 to act on the two curved faces of the cotton bale 1 to form a wedge effect, stably holding the cotton bale 1. The vehicle 2 runs along the track 9 on the track frame to reach location B and unloads the cotton bale 1.

[0025] In this embodiment, there are two rails 9, each of which is 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.

[0026] There are four track 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 the transport vehicle 2 is moved forward and backward to complete the process of transporting the cotton bale 1 from A to B.

[0027] The driving motor in the middle of the transport vehicle 2, i.e., the worm gear reducer 11, transmits power to the first driven shaft 12 through the sprocket 4 and roller chain 13 at the end of the driving shaft 15, and at the same time, transmits power to the second driven shaft 16 through the gear 22 at the other end of the driving shaft 15. The first driven shaft 12 and the second driven shaft 16 transmit power to the lifting plate shaft 5 at the lower part of the transport vehicle 2 through the sprocket 4 and roller chain 3 at the other end respectively. The lifting plates 6 are fixed by screws around the hoop 7 on the lifting plate shaft 5. Two lifting plates 6 are installed on each of the two lifting plate shafts 5. The four lifting plates 6 are distributed at the lower part of the two arc-shaped surfaces of the cotton bale 1, and the lifting plates 6 also have an outer drum-shaped arc surface, which forms a pure rolling with the arc surface of the cotton bale 1, which can not only ensure a close fit with the cotton bale 1 without slipping, but also reduce the friction 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 turned inward through gear meshing transmission and chain transmission to lift the cotton bale 1; after the transport vehicle 2 moves from A to B, the worm gear reducer 11 is reversed, and the four lifting plates 6 are synchronously turned outward to loosen and unload the cotton bale 1.
