Description

Technical Field

[0001] The utility model relates to the technical field of transport tooling, in particular to a glass storage and transportation trolley. Background Art

[0002] Glass is usually packed in wooden boxes for short-distance transportation. The packaging operation steps are complicated and consume a lot of wood. Due to the variety of glass specifications, multiple specifications of glass need to be transported in the same batch at the same time. The existing glass racks cannot accommodate multiple specifications of glass for separate placement and synchronous transportation. The main reason is that the existing glass racks can only transport glass slightly smaller than their size. Glass that is too small or too large cannot be properly supported and clamped. Therefore, glass transport racks of different specifications are required for separate transportation, which further increases the investment cost and storage space of transport tooling, reduces the utilization rate of each transport tooling, and requires more manpower or more transfer time during transportation, resulting in low operating efficiency. Therefore, the utility model is committed to solving the problem of transporting multiple specifications of glass in different areas at the same time. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A glass storage and transportation trolley comprises a chassis frame, a traction handrail and a storage and transportation frame. The traction handrail is a frame-shaped structure, and its bottom is connected to one end of the chassis frame. Universal wheels are arranged at the four corners of the bottom of the chassis frame. The storage and transportation frame is built on the chassis frame, and one end of the storage and transportation frame is connected to the traction handrail through a support beam. The storage and transportation frame divides the space on the chassis frame into two symmetrical inner storage and transportation areas and two symmetrical outer storage and transportation areas. The inner storage and transportation area is located between the two outer storage and transportation areas, and the two are arranged in parallel. One end of the two is blocked by a support beam, and the other end is an open structure; wherein,

[0006] The storage and transportation rack includes two outer brackets, several outer movable beams and several outer stops. The two outer brackets are arranged in parallel and are in an L-shaped structure. One end is connected to the support beam and the other end is connected to the bottom longitudinal beam of the chassis frame. The outer movable beam is arranged obliquely, and its upper end is connected to the outer bracket and can be slid and adjusted, and its lower end is connected to the bottom cross beam and can be slid and adjusted. The outer stop is arranged perpendicular to the outer movable beam, and is connected to the bottom cross beam and can be slid and adjusted. Several outer movable beams and several outer stops adjust the support position according to the length of the glass to be evenly distributed according to the glass surface area. The two together form an outer storage and transportation area of ​​an L-shaped structure on the outside of the outer bracket;

[0007] The storage and transportation rack also includes two inner brackets, several inner movable beams and several inner stops. The two inner brackets are arranged in parallel at intervals between the two outer brackets. The inner bracket is higher than the outer bracket and parallel to the outer bracket. The inner bracket is in an L-shaped structure, one end of which is connected to the support beam, and the other end is connected to the bottom longitudinal beam of the chassis frame.

Several inner movable beams and several inner stops are evenly distributed according to the glass area, and the support position is adjusted according to the length of the glass. The two together construct an inner storage and transportation area of ​​an L-shaped structure formed between the inner bracket and the adjacent outer bracket.

[0008] Furthermore, it also includes an internal caliper device arranged on the top of the inner bracket, and each inner storage and transportation area is equipped with at least two internal caliper devices. The internal caliper device includes an electric push rod, a lifting arm and a caliper disc. A support adjustment plate is horizontally arranged directly below the inner bracket. The electric push rod is detachably adjusted and arranged on the support adjustment plate, and is upright between the two inner brackets. The lifting arm is L-shaped and extends to the top of the inner storage and transportation area. One end of the lifting arm is connected to the output end of the electric push rod, and the other end is connected to the caliper disc through a universal joint.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only the best embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] This embodiment provides a glass storage and transportation trolley that integrates transportation and storage. Figure 1-Figure 2 As shown, it includes a chassis frame 3, a traction handrail 1 and a storage and transportation frame. The traction handrail 1 is vertically arranged at one end of the chassis frame 3, which is a frame-type structure. In order to reduce the overall weight of the storage and transportation trolley, the chassis frame 3 is formed by assembling and welding a number of bottom longitudinal beams and bottom cross beams 31. Universal wheels 2 are arranged at the four corners of the bottom, and the storage and transportation frame is built on the chassis frame 3;

[0020] The storage and transportation rack is used for carrying and storing glass. It divides the space on the chassis frame 3 into four parallel areas along the width direction, namely two symmetrical inner storage and transportation areas 5 and two symmetrical outer storage and transportation areas 4, so as to form four partitions for placing glass of various specifications. As for the specifications of glass, the article describes the four specifications of glass that can be stored by the storage and transportation rack, namely small specifications, medium specifications, large specifications and relatively large specifications; in order to facilitate the placement of glass longer than the storage and transportation trolley, the other end of the inner storage and transportation area 5 and the outer storage and transportation area 4, that is, the other end away from the traction handrail 1, are both open structures, and one end of both is connected to the traction handrail 1 through a support beam 11, forming a barrier at that end; the inner storage and transportation area 5 is located between the two outer storage and transportation areas 4, and the two are arranged in parallel. In order to better adapt to glasses of different specifications, the upper end of the inner storage and transportation area 5 is higher than the outer storage and transportation area 4;

[0021] Specifically, in order to form two symmetrical outer storage and transportation areas 4, the storage and transportation rack includes two outer brackets 41, several outer movable beams 43 and several outer stops 42. The two outer brackets 41 are arranged in parallel and have an L-shaped structure as a support for the outer storage and transportation area 4. The end of the upper horizontal tube is connected to the support beam 11, and the end of the vertical tube is connected to the bottom longitudinal beam of the chassis frame 3. The outer movable beams 43 are inclined to form an inclined outer storage and transportation area 4 on the outer side of the outer bracket 41. The glass panel is supported and positioned by the outer movable beams 43. In order to facilitate the reasonable adjustment of the support position according to the length of the glass, the several outer movable beams 43 can evenly and reasonably support the glass, especially small-sized glass and larger-sized glass whose size is larger than the outer storage and transportation area 4. The small-sized glass should be guaranteed to obtain uniform support from at least two outer movable beams 43, and the larger-sized glass extends out of the outer storage and transportation area 4 from the open structure at the other end. At this time, the outer movable beams 43 should be adjusted so that the glass surface area located in the outer storage and transportation area 4 is evenly supported, and combined with the caliper system 6 to form a stable placement Therefore, locking clips with a clamp-like structure are fixed at both ends of the outer movable beam 43, and the locking clips at the upper end can be clamped to the upper cross tube of the outer bracket 41, and the position of the upper end of the outer movable beam 43 is locked and fixed after sliding adjustment. Similarly, the position of the lower end of the outer movable beam 43 is synchronously adjusted and locked along the bottom cross beam 31 to complete the limit fixation of the outer movable beam 43; in addition, the outer stopper 42, which supports the bottom end surface of the glass, is perpendicular to the outer movable beam 43 in order to increase the supporting area. Similarly, the outer The stopper 42 is connected to the bottom cross beam 31 and can be slidably adjusted. Since the supports of the outer stopper 42 and the outer movable beam 43 need to be evenly distributed, in order to speed up the adjustment efficiency and improve the structural strength, the outer stopper 42, the outer movable beam 43 and the locking clip are an integrated structure. The outer stopper 42 can be welded on the outer movable beam 43. Of course, the two can also be split structures. Similarly, a locking clip is set on the end of the outer stopper 42 to achieve lockable adjustment. The outer stopper 42 and the outer movable beam 43 of the split structure should be staggered.

[0022] In order to form two inner storage and transportation areas 5 symmetrical with respect to the center of the trolley, the storage and transportation rack also includes two inner brackets 51, several inner movable beams 54 and several inner stoppers 53. The two inner brackets 51 are arranged in parallel between the two outer brackets 41 at intervals. The inner brackets 51 are higher than the outer brackets 41, which can realize the storage and transportation of medium and large-sized glasses. The inner brackets 51 serve as supports for the inner storage and transportation area 5. They are parallel to the outer brackets 41 and have an L-shaped structure. One end of the inner brackets 51 is connected to the support beam 11, and the other end is connected to the bottom longitudinal beam of the chassis frame 3. The beam 54 is tilted and parallel to the outer movable beam 43. Its upper end can be adjusted and locked to the upper cross tube of the inner bracket 51 through a locking clip, and its lower end can be adjusted and locked to the bottom cross beam 31 through a locking clip; the inner stopper 53 is connected to the bottom cross beam 31 and can be slidably adjusted. The inner stopper 53, the inner movable beam 54 and the locking clip can be an integrated structure, and the inner stopper 53 and the inner movable beam 54 can also be a split structure; the inner storage and transportation area 5 has the same structural design as the outer storage and transportation area 4, and the adjustment ideas are the same, which will not be repeated here;

[0023] Since the storage rack uses the gravity of the glass for support, in order to prevent the glass from being separated from the support due to vibration during transportation, the storage rack is equipped with a caliper system 6 to provide an adaptive clamping force to press the glass against the support surface; the caliper system 6 includes an inner caliper device 61, an outer caliper device 62 and a caliper control module. In order to store glasses of various specifications, the inner caliper device 61 and the outer caliper device 62 adopt different limit structures. Figure 1-Figure 2 Each inner storage and transportation area 5 is equipped with at least two inner clamp devices 61, and each outer storage and transportation area 4 is equipped with at least two outer clamp devices 62, and both can be adapted to the size of the glass to adjust the clamping position;

[0024] The inner clamp device 61 includes an electric push rod 612, a lifting arm 611 and a clamp plate 623. A support adjustment plate 52 is horizontally arranged directly below the inner bracket 51. The support adjustment plate 52 is fixed to the vertical tube of the inner bracket 51 and the support beam 11. The electric push rod 612 is detachably mounted on the support adjustment plate 52 by screws. A plurality of mounting holes are evenly distributed on the support adjustment plate 52. The position of the electric push rod 612 is adjusted according to the different clamping positions of the glass of different lengths, and the appropriate mounting holes are selected for fixing. The electric push rod 612 is arranged vertically, and its driving rod is composed of two The lifting arm 611 extends between the inner brackets 51, and the end is connected to the lifting arm 611 of L-shaped structure. The lifting arm 611 extends to the top of the middle of the inner storage and transportation area 5. The lifting stroke is designed according to the minimum size of the medium-sized glass in the inner storage and transportation area 5. The bottom of the end of the lifting arm 611 is connected to the clamp plate 623 through a universal joint. The clamp plate 623 faces downward. As the electric push rod 612 rises and falls, it can press the glass surface of different specifications in the inner storage and transportation area 5, or the glass surface of larger specifications beyond the inner storage and transportation area 5. The clamp plate 623 also adapts to the inclination of the glass surface to press;

[0025] The outer clamp device 62 includes a driving motor 622 and a rotating arm 621. Similarly, the rotating arm 621 is in an L-shaped structure. The length of the rotating arm 621 is designed according to the minimum height of the small-sized glass to be stored. A clamp plate 623 is arranged at the end of the rotating arm 621 through a universal joint. The clamp plate 623 faces downward. The driving motor 622 is clamped on the upper transverse tube of the outer bracket 41 through a plurality of clamp structures. The driving motor 622 can be slidably adjusted and locked in position to adapt to the glass of different lengths in the outer storage and transportation area 4. Under the drive of the driving motor 622, the rotating arm 621 rotates forward and backward in the outer storage and transportation area 4, and the clamp plate 623 adaptively presses the glass surface.

[0026] Next, in combination with the storage and transportation rack structure, it is briefly described how to use the inner caliper device 61 and the outer caliper device 62 of different structures to reasonably realize the storage of four specifications of glass classified by height; the glass with a height less than the outer storage and transportation area 4 is defined as the small-size glass in the text, which can be stored in the two outer storage and transportation areas 4, and at the same time, it is compressed by the outer caliper device 62 that rotates to achieve compression; the glass with a height greater than the outer storage and transportation area 4 and smaller than the inner storage and transportation area 5 is defined as the medium-size glass, which can be stored in the two inner storage and transportation areas 5, and compressed by the inner caliper device 61 that lifts and lowers to achieve compression; the glass with a height greater than the inner storage and transportation area 5 is defined as the medium-size glass. Glass is defined as large-format glass and can be stored in the inner storage and transportation area 5, and can be compacted by the internal caliper device 61 that is lifted and lowered to achieve compaction; glass that is higher than the large-format glass is defined as large-format glass and can be stored in the outer storage and transportation area 4. Due to the interference of the internal caliper device 61, the inner storage and transportation area 5 cannot be used to store large-format glass. The large-format glass is placed in the outer storage and transportation area 4, and is compacted by the internal caliper device 61 that is lifted and lowered. Since the compaction force is located outside the support surface of the outer movable beam 43, the compaction force of the clamp plate 623 should not be too large to prevent the glass from tilting and detaching from the support of the outer stopper 42 at the bottom.

[0027] In order to realize closed-loop automatic control of the clamping force and prevent excessive clamping force from damaging the glass, firstly, the clamping disc surface of the clamping disc 623 is made of rubber veneer, and a pressure sensor is embedded in it to collect the clamping force data of the clamping disc 623 in real time and feed it back to the caliper control module to close the loop and adjust the output of the electric push rod 612 and the drive motor 622.

[0028] In addition, all surfaces of the outer bracket 41 , the inner bracket 51 , the outer stopper 42 , the inner stopper 53 , the inner caliper device 61 , and the outer caliper device 62 that are in contact with the glass or may touch the glass are covered with cushioning cotton.
