Description

Technical Field

[0001] The present invention relates to the technical field of transportation vehicle structures, and particularly to a transporting vehicle for raw bamboo and its transporting method. Background Art

[0002] Chinese Patent with publication number CN102152754A discloses a semi-trailer type log transporting vehicle. In its structure, by arranging a telescopic towing pipe between the front and rear vehicle frames, the distance between the front and rear vehicle frames can be adjusted, so as to be applicable to the loading and transportation of logs with different lengths.

[0003] However, the telescopic towing pipe structure makes the front and rear vehicle frames rigidly connected. When used for transporting raw bamboo, since the length of the raw bamboo is significantly longer than that of the log, the connection method of connecting the front and rear vehicle frames through the telescopic towing pipe limits the extension length between the front and rear vehicle frames, and the connection structure of the telescopic towing pipe makes the distance between the front and rear vehicle frames unable to be fully shortened when the transporting vehicle is unloaded, affecting the traveling efficiency of the transporting vehicle in the unloaded state. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a transporting vehicle for raw bamboo and its transporting method, which can keep the front and rear vehicle frames at a very close distance when unloaded, fully reducing the vehicle length, and when in the transporting state, the front and rear vehicle frames can be fully adjusted to a bearing distance suitable for the length of the raw bamboo.

After the steel wire rope wound around the first winch is wound around two rope winding wheels in sequence, it is led crosswise and wound around the second winch. In the second state, the hanging buckle is separated from the hanging cylinder, and the front and rear vehicle frames move away from each other, increasing the distance between the front vehicle frame body and the rear vehicle frame body. The first winch and the second winch release the steel wire rope simultaneously.

[0006] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, the side of the support rod is an arc surface with a smooth material layer, and the intersection point of the steel wire ropes is located behind the support rod.

[0007] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, the support rod is a telescopic cylinder.

[0008] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, the telescopic cylinder is an air cylinder, an electric cylinder or a hydraulic cylinder.

[0009] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, the tail wheel assembly includes: A first bearing seat, which is connected to the support frame; A first wheel shaft, which is rotatably connected to the first bearing seat; A second wheel shaft, and the two second wheel shafts are respectively connected to the first wheel shaft through universal couplings; A tail wheel body, which is connected to the second wheel shaft; A second bearing seat, which is rotatably connected to the second wheel shaft; A swing rod, one end of which is connected to the upper part of the second bearing seat; A connecting rod, and both ends of the connecting rod are pivotally connected to the other ends of the two swing rods respectively.

[0010] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, a first connection hole is provided in the middle of the connecting rod, a second connection hole is provided on the support frame, and a U-shaped connecting piece is further included. The two ends of the U-shaped connecting piece are respectively detachably inserted into the first connection hole and the second connection hole.

[0011] Furthermore, in the above-mentioned structure of the moso bamboo raw bamboo transport vehicle, a plurality of limiting convex blocks are arranged on the bearing plate in a lateral one-word array. The shape of the limiting convex block is a triangular prism, and one of the side edges of the triangular prism faces upward.

[0012] Furthermore, in the above-mentioned raw bamboo transport vehicle structure, the hook and clasp includes a fixed portion and a movable clasping portion, the front end of the fixed portion is provided with a first arc-shaped groove, the side of the first arc-shaped groove is provided with a first connecting plate, the first connecting plate is provided with a third connecting hole, the movable clasping portion is provided with a second arc-shaped groove opposite to the first arc-shaped groove, one side of the movable clasping portion is pivotally connected to one side of the fixed portion, the other side of the movable portion is provided with a second connecting plate, and the second connecting plate is provided with a fourth connecting hole; In the hanging state, the first arc groove and the second arc groove of the hanging buckle are connected to the connecting column of the front frame and are locked by bolts passing through the third connecting hole and the fourth connecting hole.

[0013] The present invention also relates to a transportation method of a raw bamboo transport vehicle. Based on the above raw bamboo transport vehicle, the transportation method comprises the following steps: When the transport vehicle is empty, the rear frame body is connected to the hooking cylinder of the front frame body through the hooking buckle; When it is necessary to load raw bamboo, the hooking buckle of the rear frame body is separated from the hooking cylinder of the front frame body; the first winch and the second winch release the wire rope at the same time, and the front frame body moves forward under the drive of the power locomotive, so that the distance between the front frame body and the rear frame body is increased to a length close to that of the raw bamboo; the two ends of the raw bamboo are respectively placed on the U-shaped bracket and the load-bearing plate.

[0014] The beneficial effects of the present invention are as follows: the front frame body and the rear frame body adopt a connection structure of two winches and two rope winding wheels. In the second state, i.e., when loaded with raw bamboo, the distance between the front frame body and the rear frame body can be flexibly and infinitely adjusted by unwinding the first winch and the second winch; the wire rope is wound in a cross-type manner between the front and rear frames, effectively increasing the wrap angle between the wire rope and the rope winding wheels and improving the stability of the rope winding. In the first state, i.e., the unloaded state, the rear frame body can be connected to the hanging cylinder of the front frame body through the hanging buckle, and the wire rope can be wound by the first winch and the second winch. In this way, the length of the transport vehicle is greatly shortened when unloaded, thereby improving travel efficiency.

[0015] When the transport vehicle turns, since the U-shaped bracket is rotatably connected to the front frame, the power locomotive will drive the front frame body to rotate, and the U-shaped bracket will maintain its original angle under the positioning of the bamboo itself, and the rear frame body will also maintain its original angle, which will cause an angle of deviation between the rear frame body and the front frame body. At this time, the two winches do not need to retract or release the wire rope, and the wire rope at the outer corner of the turn will be stretched to a certain extent. The wire rope will be displaced to a certain extent between the two rope winding wheels at the rear to adapt to the wire rope displacement in this turning state, thereby keeping the connection between the front and rear frames stable.

[0017] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0018] Referring to Figures 1 to 4 , a specific embodiment of the present invention relates to a moso bamboo raw bamboo transport vehicle, including: Power head 1; Front frame body 2, the front frame body 2 is hung on the power head 1; U-shaped bracket 21, the U-shaped bracket 21 is rotatably connected to the front frame body 2; Hanging cylinder 22, both ends of the hanging cylinder 22 are connected to the rear part of the front frame body 2 through connecting ear plates; First winch 23, the first winch 23 is connected to the rear part of the front frame body 2; Second winch 24, the second winch 24 is connected to the rear part of the front frame body 2, and the first winch 23 and the second winch 24 are symmetrically distributed left and right; The rear frame body 3 includes a support frame 31, a carrying plate 32, a tail wheel assembly 33, a hanging link 34, a hanging buckle 35, a rope winding wheel 36, a support rod 37, a support wheel 38 and a limit rod 39; the tail wheel assembly 33 is connected to the support frame 31, the carrying plate 32 is connected to the upper part of the support frame 31, and the two rope winding wheels 36 are connected to the support frame 31 in a left-right symmetrical distribution; the hanging link 34 is connected to the front part of the support frame 31, the hanging buckle 35 is connected to the front end of the support frame 31, one end of the support rod 37 is connected to the lower part of the hanging link 34, the lower end of the support rod 37 is connected to the support wheel 38, and the two limit rods 39 are respectively connected to both sides of the upper part of the carrying plate 32; In the first state, the hooking buckle 35 is hooked to the hooking cylinder 22, and the wire rope 310 attached to the first hoist 23 is sequentially wound around the two rope winding wheels 36, and then cross-directed to and wound around the second hoist 24; In the second state, the hooking buckle 35 is separated from the hooking cylinder 22, and the front and rear frames move back to back, so that the distance between the front frame body 2 and the rear frame body 3 is increased, and the first winch 23 and the second winch 24 simultaneously unwind the wire rope 310.

[0019] The present invention also relates to a transportation method of a raw bamboo transport vehicle. Based on the above raw bamboo transport vehicle, the transportation method comprises the following steps: When the transport vehicle is empty, the rear frame body 3 is connected to the hanging cylinder 22 of the front frame body 2 through the hanging buckle 35; When it is necessary to load raw bamboo, the hooking buckle 35 of the rear frame body 3 is separated from the hooking cylinder 22 of the front frame body 2; the first winch 23 and the second winch 24 simultaneously release the wire rope 310, and at the same time, the front frame body 2 moves forward under the drive of the power head 1, so that the distance between the front frame body 2 and the rear frame body 3 is increased to a length close to that of the raw bamboo; the two ends of the raw bamboo are respectively placed on the U-shaped bracket 21 and the load-bearing plate 32.

[0020] In the above embodiment, the front frame body 2 and the rear frame body 3 utilize a connection structure consisting of two winches and two rope winding wheels 36. In the second state, i.e., when loaded with raw bamboo, the spacing between the front frame body 2 and the rear frame body 3 can be flexibly and infinitely adjusted by unwinding the first winch 23 and the second winch 24. The wire rope 310 is wound crosswise between the front and rear frames, effectively increasing the wrap angle between the wire rope 310 and the rope winding wheels 36 and improving the stability of the winding. In the first state, i.e., when unloaded, the rear frame body 3 can be connected to the attachment cylinder 22 of the front frame body 2 via the attachment buckle 35, and the wire rope 310 can be reeled in by the first winch 23 and the second winch 24. This significantly shortens the length of the transport vehicle when unloaded, thereby improving travel efficiency.

[0021] In the second state, i.e., the loading state, since the front frame body 2 and the rear frame body 3 are connected by a steel wire rope 310, and both ends of the raw bamboo are respectively placed on the bearing plate 32 and the U-shaped bracket 21. When the transport vehicle turns, since the U-shaped bracket 21 is rotatably connected to the front frame, the power head 1 will drive the front frame body 2 to rotate. Under the positioning of the raw bamboo itself, the U-shaped bracket 21 will maintain its original angle, and the rear frame body 3 will also maintain its original angle. This results in a deflection angle between the rear frame body 3 and the front frame body 2. At this time, the two winches do not need to retract or release the steel wire rope 310, and the steel wire rope 310 at the outer corner of the turn will be stretched to a certain extent, and the steel wire rope 310 will displace between the two rear rope winding wheels 36 to adapt to the displacement of the steel wire rope 310 in this turning state, so as to keep the connection between the front and rear frames stable.

[0022] As a preferred embodiment, the side of the support rod 37 is an arc surface with a smooth material layer, and the intersection point of the steel wire ropes 310 is located behind the support rod 37.

[0023] Refer to Figure 4 , in the above embodiments, the intersection point of the steel wire ropes 310 is arranged behind the support rod 37. The advantage of this design is that no matter how much the distance between the front frame body 2 and the rear frame body 3 is stretched, the wrap angle between the steel wire ropes 310 and the two rope winding wheels 36 is always kept stable, thus further ensuring the connection stability between the rope winding wheels 36 and the steel wire ropes 310. Suppose the intersection point of the wound ropes is arranged in front of the support rod 37, then as the distance between the front frame body 2 and the rear frame body 3 increases, the position of the intersection point will move forward continuously, resulting in a decrease in the wrap angle between the rope winding wheels 36 and the steel wire ropes 310, reducing the stability of the rope winding, and there is a risk that the steel wire ropes 310 will break away from the rope winding wheels 36.

[0024] As a preferred embodiment, the support rod 37 is a telescopic cylinder.

[0025]

[0026] In the above embodiments, the support rod 37 not only plays a role in supporting the rear frame body 3 after it disengages from the front frame body 2, but also plays a role in limiting and guiding the steel wire ropes 310, and also plays a role in adjusting the angle of the bearing plate 32 of the rear frame body 3. When the raw bamboo is erected on the front and rear frames, due to the density difference of different bamboos, the middle part of the bamboo will sink to a certain extent without support, resulting in a certain bending of the bamboo placed on the bearing plate 32 of the rear frame body 3. By adjusting the bearing plate 32 to an appropriate inclination angle to make it completely fit the inclination angle of the raw bamboo, the rear end part of the raw bamboo can be carried more stably.

[0027] As a preferred embodiment, the trailing wheel assembly 33 includes: A first bearing block 331, which is connected to the support frame 31; A first wheel shaft 332, which is rotatably connected to the first bearing block 331; A second wheel shaft 334, and the two second wheel shafts 334 are respectively connected to the first wheel shaft 332 through universal couplings 333; A trailing wheel body 335, which is connected to the second wheel shaft 334; A second bearing block 336, which is rotatably connected to the second wheel shaft 334; A swing rod 337, one end of which is connected to the upper part of the second bearing block 336; A connecting rod 338, and both ends of the connecting rod 338 are pivotally connected to the other ends of the two swing rods 337 respectively.

[0028] In the above embodiments, in the later stage of the transport vehicle turning, the rear frame body 3 also needs to turn. By setting the structure of the above trailing wheel assembly 33, a certain deflection angle can be generated between the trailing wheel body 335 and the first wheel shaft 332 when the rear frame body 3 turns, which is convenient for the vehicle to turn.

[0029] As a preferred embodiment, a first connection hole is provided in the middle of the connecting rod 338, a second connection hole is provided on the support frame 31, and a U-shaped connecting piece 339 is further included. The two ends of the U-shaped connecting piece 339 are respectively detachably inserted into the first connection hole and the second connection hole.

[0030] In some straight road conditions or when it is out of use, the two ends of the U-shaped connecting piece 339 can be respectively inserted into the first connection hole and the second connection hole to fix the connecting rod 338 relative to the support frame 31, so that the trailing wheel body 335 is controlled to be in a state coaxial with the first rotating shaft, restricting the axial deflection of the trailing wheel body 335.

[0031] As a preferred embodiment, a plurality of limiting bumps 321 are provided on the bearing plate 32 and are distributed in a lateral one-word array. The limiting bumps 321 are in the shape of a triangular prism, and one of the side edges of the triangular prism faces upward.

[0032] In the above embodiments, the triangular prism provides auxiliary limitation for the original bamboo of the moso bamboo, avoiding the lateral rolling of the moso bamboo during the transportation process.

[0033] As a preferred embodiment, the hanging buckle 35 includes a fixing part and a movable clamping part. The front end of the fixing part is provided with a first arc-shaped groove 351. A first connecting plate 353 is arranged on the side of the first arc-shaped groove 351. The first connecting plate 353 is provided with a third connecting hole. The movable clamping part is provided with a second arc-shaped groove 352 opposite to the first arc-shaped groove 351. One side of the movable clamping part is pivotally connected to one side of the fixing part. The other side of the movable part is provided with a second connecting plate 354. The second connecting plate 354 is provided with a fourth connecting hole; In the hanging state, the first arc-shaped groove 351 and the second arc-shaped groove 352 of the hanging buckle 35 are clamped on the connecting column of the front frame, and are locked by bolts passing through the third connecting hole and the fourth connecting hole.

[0034] The above structure can realize the detachable connection between the hanging buckle 35 of the rear frame body 3 and the clamping cylinder of the front frame body 2.

[0035] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
