Description

Technical Field

[0001] The utility model relates to a storage rack structure, in particular to a scissor-type self-balancing storage rack structure. Background Art

[0002] In recent years, agricultural transport machinery has gradually become popular. However, due to the large number of mountainous areas in my country, there are still many places that cannot be reached by tractors. The transportation efficiency of mountain crops, including fruits and vegetables, is still low, and large-scale planting cannot be formed.

[0003] Therefore, rail conveyors have appeared on the market. They lay tracks on mountainous areas, which can enable the conveyor to start and stop at any time in the mountains to load and transport agricultural products. Such rail conveyors usually include tractors, trailers and tracks. The tractors and trailers are mounted on the tracks and move along the tracks. When in use, the tractor serves as the power output and runs on the tracks with the trailer, while the agricultural products are stored on the trailer. Since the operating environment of rail conveyors is mostly mountainous, its tracks are steeply inclined and curved, which may cause the agricultural products stored in the trailer to roll down, causing damage to the agricultural products and seriously affecting the economic income of farmers.

[0004] Therefore, the applicant previously applied for a self-balancing storage rack structure for a track machine, which is intended to prevent agricultural products from rolling off the trailer during operation. It has indeed received a good response in the market. However, while receiving positive feedback from customers, some objective defects have also been reported: 1. The storage rack is set on the trailer frame and adopts a hanging rope structure. It uses its own gravity as the force to achieve a natural vertical state. The overall structural size is large and the manufacturing cost is also high; 2. The hanging rope structure has a high overall center of gravity, poor stability, and is easy to shake; 3. The design of a single-piece arc guide rail and a single guide wheel adopts a single-piece arc guide rail. When the storage rack rotates under its own gravity, it is easy to get stuck during long-term use; 4. The combination of the single-piece arc guide rail and the one-way wheel has an unreasonable structural design. The weight of the entire storage rack is all pressed on the one-way wheel under the arc guide rail, and there is no limit above the arc guide rail. This causes the storage rack to easily jump when it is bumped by the trailer frame. Summary of the Invention

[0005] The utility model aims to solve the existing technical problem and provide a scissor-type self-balancing storage rack structure, which optimizes the previous design scheme and makes up for various defects.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] The yoke is connected to the trailer frame by a scissor-type self-balancing storage rack structure, wherein the scissor-type structure comprises a first swing arm and a second swing arm, wherein the lower ends of the first swing arm and the second swing arm are hingedly connected together, and the upper end of the first swing arm is hingedly connected to the trailer frame, and the upper end of the second swing arm is hingedly connected to the storage rack, so that when the storage rack rotates relative to the trailer frame to a vertical state under the action of its own gravity, the storage rack is in an open state relative to the second swing arm, the second swing arm is in an open state relative to the first swing arm, and the first swing arm is in an open state relative to the trailer frame; a symmetrical guide mechanism is further provided between the storage rack and the trailer frame, wherein the guide mechanism comprises an arc guide rail, at least two lower guide wheels and at least one upper guide wheel, the upper guide wheel matches the upper surface of the arc guide rail, the lower guide wheel matches the lower surface of the arc guide rail, and the lower guide wheel has a shock-absorbing and buffering effect on the arc guide rail.

[0008] Half of the circumference of the arc guide rail is greater than half of the circumference of a circle formed by the maximum rotation radius of the storage rack with the hinge point of the swing arm on the trailer frame as the center.

[0009] Compared with the prior art, when the trailer frame is tilted, the storage rack of the utility model rotates around multiple hinge points through the swing arm 1 and the swing arm 2, thereby completing the change from the tilted state to the vertical state; the design of the swing arm 1 and the swing arm 2 has better stability and directionality than the design of the suspension rope of the previous generation product, which greatly reduces the shaking of the storage rack. In addition, in order to keep the storage rack stable, we have added a guide mechanism, which has at least one upper guide wheel and only two lower guide wheels, which greatly improves the stability of the storage rack in a stable posture and further makes the storage rack maintain a vertical state with directionality. , avoiding the phenomenon of shaking around, and getting rid of the problem of bumps, moreover, the lower guide wheel has a shock-absorbing and buffering effect on the arc guide rail. When the storage rack is full of agricultural products, the storage rack has a buffering capacity, and the friction between the arc guide rail and the upper guide wheel and the lower guide wheel is always maintained in a more appropriate state, avoiding the situation where the arc guide rail cannot move relative to the upper guide wheel and the lower guide wheel; moreover, the relationship between the circumference of the arc guide rail and the rotation radius of the swing arm one and the swing arm two can prevent the arc guide rail from separating from the lower guide wheel during the rotation and swinging process. Compared with the previous generation of products, the limit block is cancelled, thereby reducing the manufacturing cost.

[0010] Preferably, the first swing arm and the second swing arm are arranged in parallel, and the length of the first swing arm is equal to the length of the second swing arm.

[0011] The lower guide wheel is mounted on a wheel seat, which has a guide plate. The guide plate is embedded in the guide hole of the mounting seat. A spring is provided between the guide plate and the mounting seat, and the spring has a buffering effect on the downward force from the lower guide wheel.

[0012] The lower guide wheel, wheel seat and mounting seat can be installed on the trailer frame as a module, thereby greatly optimizing the installation efficiency and forming product standardization.

[0013] Preferably, there are two lower guide wheels and one upper guide wheel, the two lower guide wheels are arranged symmetrically with respect to the center line of the arc guide rail, and one upper guide wheel and two lower guide wheels form an isosceles triangle layout.

[0014] The upper guide wheel and two lower guide wheels arranged in an isosceles triangle make the guiding effect on the arc guide rail more uniform and stable, and also limit the arc guide rail to prevent it from derailing.

[0015] The upper guide wheel and the lower guide wheel both include a wheel body and baffles arranged at both ends of the wheel body with an outer diameter larger than the outer diameter of the wheel body. The width of the arc guide rail is less than or equal to the length of the wheel body.

[0016] The upper guide wheel and the lower guide wheel with baffles can firmly limit the arc guide rail on the wheel body, thereby improving safety.

[0017] The beneficial effects of the utility model are:

[0018] Compared with the existing technology, the scissor-type self-balancing storage rack structure of the utility model realizes the rotational swinging movement of the storage rack relative to the trailer frame through the swinging function of the swing arm one and the swing arm two, thereby greatly lowering the working center of gravity of the storage rack and reducing the manufacturing cost. By lowering the center of gravity of the storage rack, the stability is improved in disguise and the crops in the storage rack are protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] See also Figures 1 to 5 The utility model provides a scissor-type self-balancing storage rack structure, which is arranged on a trailer frame 1 and includes a storage rack 2. The storage rack 2 is hingedly connected to the trailer frame 1 through a scissor-type structure. The scissor-type structure includes a swing arm 1 3 and a swing arm 2 4 which are parallel in the spatial plane. The lower ends of the swing arm 1 3 and the swing arm 2 4 are hingedly connected together, and the upper end of the swing arm 1 3 is hinged to the trailer frame 1, and the upper end of the swing arm 2 4 is hinged to the storage rack 2, so that the storage rack 2 on the trailer frame 1 can be hinged relative to the trailer frame under the action of its own gravity. When the frame 1 rotates to a vertical state, the storage rack 2 is in an open state relative to the swing arm 2 4, the swing arm 2 4 is relative to the swing arm 1 3, and the swing arm 1 3 is relative to the trailer frame 1; a symmetrical guide mechanism is also provided between the storage rack 2 and the trailer frame 1, and the guide mechanism includes an arc guide rail 5, at least two lower guide wheels 6 and at least one upper guide wheel 7, the upper guide wheel 7 is matched with the upper surface of the arc guide rail 5, the lower guide wheel 6 is matched with the lower surface of the arc guide rail 5, and the lower guide wheel 6 has a shock-absorbing and buffering effect on the arc guide rail 5.

[0026] Since the storage rack 2 is supported by the guide mechanism, when the trailer frame 1 is in a horizontal state, the angle between the swing arm 1 3 and the swing arm 2 4 is 0 degrees, and when the trailer frame 1 is in a non-horizontal state, the angle between the swing arm 1 3 and the swing arm 2 4 is greater than 0 degrees, so that the storage rack 2 is always in a vertical state.

[0027] Half of the circumference of the arc guide rail 5 is greater than half of the circumference of the circle formed by the maximum rotation radius of the storage rack 2 with the hinge point of the swing arm 3 on the trailer frame 1 as the center. This design can prevent the arc guide rail 5 from separating from the lower guide wheel 6 during the rotation and swinging process. Compared with the previous generation of products, the limit block is eliminated, thereby reducing manufacturing costs.

[0028] In order to buffer the bumpy force of the storage rack 2, we have improved the shock-absorbing and buffering capacity of the lower guide wheel 6. Specifically: the lower guide wheel 6 is mounted on the wheel seat 8, and the wheel seat 8 has a guide plate 9. The guide plate 9 is embedded in the guide hole 11 of the mounting seat 10. A spring 12 is provided between the guide plate 9 and the mounting seat 10. The spring 12 has a buffering effect on the downward force from the lower guide wheel 6.

[0029] The lower guide wheel 6 , the wheel seat 8 and the mounting seat 10 can be installed on the trailer frame 1 as a module, thereby greatly optimizing the installation efficiency and forming product standardization.

[0030] Preferably, there are two lower guide wheels 6 and one upper guide wheel 7, the two lower guide wheels 6 are arranged symmetrically with respect to the center line of the arc guide rail 5, and one upper guide wheel 7 and two lower guide wheels 6 form an isosceles triangle layout.

[0031] The upper guide wheel 7 and the two lower guide wheels 6 arranged in an isosceles triangle make the guiding effect on the arc guide rail 5 more uniform and stable, and also play a limiting role on the arc guide rail 5 to prevent it from derailing.

[0032] The upper guide wheel 7 and the lower guide wheel 6 each include a wheel body 13 and baffles 14 arranged at both ends of the wheel body 13 with an outer diameter larger than that of the wheel body 13 . The width of the arc guide rail 5 is less than or equal to the length of the wheel body 13 .

[0033] The upper guide wheel 7 and the lower guide wheel 6 with the baffle 14 can stably restrict the arc guide rail 5 on the wheel body 13, thereby improving safety.

[0034] In summary, the scissor-type self-balancing storage rack structure of the present invention, the design of the swing arm 1 3 and the swing arm 2 4 reduces the shaking of the storage rack 2; the guide mechanism further improves the stability of the storage rack 2 in a stable posture, and further enables the storage rack 2 to maintain a vertical state with directionality, avoiding the phenomenon of shaking around, and getting rid of the problem of bumps, and the lower guide wheel 6 has a shock-absorbing and buffering effect on the circular guide rail 5. When the storage rack 2 is full of agricultural products, the storage rack 2 has a buffering capacity, and also makes the friction between the circular guide rail 5 and the upper guide wheel 7 and the lower guide wheel always maintain a relatively appropriate state, avoiding the situation where the circular guide rail 5 cannot move relative to the upper guide wheel 7 and the lower guide wheel.
