Description

Technical Field

[0001] The utility model relates to the technical field of bellows storage, in particular to a bellows stacking rack. Background Art

[0002] PE bellows, namely a plastic protection sleeve extruded from polyethylene material, is also called bellows because of its annular corrugated shape inside and outside, which plays a role in protecting cables from damage and also has characteristics such as good wear resistance and corrosion resistance.

[0003] The utility model patent with the publication number of CN 211443729 U and the publication date of September 8, 2020 discloses a PE bellows pipe stacking rack, which includes a main frame, a lifting plate and a suspension arm. A positive and negative motor is fixedly connected to the top of the partition board. A wire winding roller is rotatably connected to the outside of the positive and negative motor. A steel cable is rotatably connected to the surface of the wire winding roller. One end of the steel cable far away from the wire winding roller is fixedly connected to the lifting plate. A driving motor is fixedly connected to the inside of the lifting plate. A transmission shaft is rotatably connected to the top of the driving motor. A rotating table is fixedly connected to the top of the transmission shaft. A limiting block is fixedly connected to the other end of the suspension arm far away from the column;

[0004] The utility model facilitates the staff to store and take PE bellows placed at high positions and deep inside the stacking rack by setting the lifting plate and the rotating table, greatly improving the utilization rate of the internal space of the storage box and ensuring that the bellows are not knocked and injured when being accessed, providing great convenience for storing bellows;

[0005] However, the utility model has the following problems in the specific implementation process: 1. The entire stacking rack realizes lifting by driving the lifting plate with a positive and negative motor during use, which makes the stacking rack highly dependent on external power sources. According to the actual production site, it is found that when bellows are stacked, it is mostly carried out in the open space outside the workshop. In this case, it is very cumbersome to connect power to the positive and negative motor additionally. Therefore, the applicability of the entire stacking rack is not high;

[0006] 2. The entire stacking rack occupies too much area during use. Specifically, the suspension arms are installed circumferentially on the column 13. After inserting the bellows onto two opposite suspension arms, the length of the entire stacking rack at this time is equal to the sum of the lengths of the two bellows, which increases the space occupied by the entire stacking rack and is very inconvenient to move.

[0007] Therefore, there is an urgent need for a bellows stacking rack to improve the applicability of the stacking rack and reduce the space occupation. Utility Model Content

[0008] In view of the above technical problems, the present utility model provides a corrugated pipe stacking rack, which is used to solve the problems that the existing stacking racks rely too much on external power sources during use, resulting in low applicability and large space occupation.

[0009] The above technical object of the present utility model is achieved through the following technical solutions:

[0010] A corrugated pipe stacking rack includes a chassis. A plurality of upright columns are arranged in parallel on the chassis. A cross beam is connected between the ends of the plurality of upright columns away from the chassis. A guiding beam is arranged on the upright column along the length direction. A sliding groove is opened along the length direction on the guiding beam. A first support arm, a second support arm and a third support arm are sequentially slidably arranged in the sliding groove from top to bottom;

[0011] One ends of the first support arm, the second support arm and the third support arm located in the sliding groove are all provided with sliders. A braking hole is respectively penetrated through both ends of the slider perpendicular to the axis direction of the upright column. A plurality of adjusting holes are penetrated through the guiding beam perpendicular to the length direction. A detachable braking member is arranged between the braking hole and the adjusting hole;

[0012] A first retaining arm is arranged at the end of the first support arm, the second support arm and the third support arm;

[0013] The first support arm, the second support arm and the third support arm are symmetrically arranged on both sides of the upright column, and the first support arm, the second support arm and the third support arm form an isosceles triangle structure through the upright column.

[0014] Further, at least one overlapping arc opening is opened on the first support arm, the second support arm and the third support arm.

[0015] Further, a plurality of second retaining arms are vertically arranged between the first retaining arm and the upright column on the first support arm, the second support arm and the third support arm.

[0016] Further, the braking member includes two parallel first pins. A connecting member is arranged between one ends of the two first pins. The distance between the two first pins is equal to the distance between the two braking holes.

[0017] Further, a support column is hinged to the end of the third support arm away from the upright column. A clamping member is arranged on the chassis at the position where the support column is in a vertical state. A second pin is arranged between the clamping member and the support column.

[0018] Further, the lengths of the first support arm, the second support arm and the third support arm increase in sequence.

[0019] Further, the distance between two adjacent adjusting holes is equal to half of the distance between the two braking holes.

[0020] Further, a plurality of self-locking universal wheels are provided at the bottom of the chassis.

[0021] Further, both the slider and the sliding groove are of T-shaped structure.

[0022] In summary, the beneficial technical effects of the present utility model are as follows:

[0023] (1) By using the braking member in cooperation with the adjusting hole, the first support arm, the second support arm and the third support arm can be lifted and lowered along the column, and the distance between the three can be flexibly changed according to the diameter of the corrugated pipe, thereby replacing the original purpose of lifting by relying on an external power source, enabling the entire stacking rack to be used under any working conditions, thus improving the applicability of the stacking rack. In addition, by changing the stacking method of the corrugated pipe through the first support arm, the second support arm and the third support arm, the corrugated pipe can be stacked side by side, reducing the length of the entire stacking rack when stacking the same number, greatly reducing the space occupied by the entire stacking rack, and also increasing the stacking quantity of the corrugated pipe.

[0024] (2) By using the isosceles triangle structure formed by the first support arm, the second support arm, the third support arm and the column, when placing the corrugated pipe, the quantity of the corrugated pipe stacked at the bottom of the stacking rack is large and the weight is heavy, thereby shifting the center of gravity of the entire stacking rack downward, making the stacking more stable.

[0025] (3) By using the connecting member to connect the two first pins into a whole, the operation process and time are reduced when sliding the first support arm, the second support arm and the third support arm.

[0026] (4) By using the support column, the support strength of the third support arm is increased, avoiding the problem of sagging when the stacking quantity on the third support arm is large.

[0027] (5) By using the first retaining arm, the corrugated pipe can be restricted to prevent it from falling. At the same time, by using the second retaining arm, two corrugated pipes can be separated to prevent multiple corrugated pipes from being squeezed together, which is inconvenient for taking and placing.

Specific embodiments

[0035] The present utility model will be clearly and completely described below in conjunction with the embodiments.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0037] In the description of the embodiments, unless otherwise clearly defined and limited, terms such as "arranged", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or connected through an intermediate medium, or the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] See the appendix Figures 1-6, shown is a corrugated pipe stacking rack, including a chassis 1. At the bottom of the chassis 1, there are multiple self-locking universal wheels 2 for flexibly moving the entire stacking rack. On the other side of the chassis 1, three upright columns 3 are installed in parallel and on the same plane through bolts. On the front and back sides of the upright columns 3, a guiding beam 5 is symmetrically fixed respectively. The guiding beam 5 is provided with a T-shaped structure chute 6 along the length direction. In the chute 6, a first support arm 7, a second support arm 8, and a third support arm 9 are sequentially slidably arranged. One end of the first support arm 7, the second support arm 8, and the third support arm 9 close to the chute 6 is connected with a slider 10. The slider 10 is slidably matched with the chute 6. At the same time, the lengths of the first support arm 7, the second support arm 8, and the third support arm 9 increase sequentially according to a tolerance of 200 mm. In this way, the entire stacking rack forms an isosceles triangle structure. When in use, the corrugated pipes are horizontally placed on the first support arm 7, the second support arm 8, and the third support arm 9. Compared with the comparative document in the background art, on the premise of stacking the same number of corrugated pipes, the length of the space occupied by the present utility model is half of the length of the stacking rack in the comparative document. In this way, the space occupation is greatly reduced;

[0039] In addition, through the first support arm 7, the second support arm 8, and the third support arm 9 with sequentially increasing lengths, when stacking the corrugated pipes, the entire stacking rack can present an effect of being lighter at the upper part and heavier at the lower part in terms of weight. In this way, the center of gravity of the entire stacking rack is lowered, thereby improving the stability during stacking;

[0040] The upright column 3 is provided with a plurality of adjustment holes 12 penetrating in a direction perpendicular to the axis of the upright column 3 at the positions of the first support arm 7, the second support arm 8, and the third support arm 9. At the same time, the two ends of the slider 10 are also provided with braking holes 11 with the same diameter as the adjustment holes 12, and the distance between adjacent two adjustment holes 12 is equal to half of the distance between the two braking holes 11. A braking member 13 is inserted between the braking hole 11 and the adjustment hole 12. Through the braking member 13, the height and the mutual distance of the first support arm 7, the second support arm 8, and the third support arm 9 on the upright column 3 are adjusted. Compared with the comparative document, when realizing the height adjustment, it gets rid of the dependence on external power supply, and thus can be applicable to any stacking working condition, improving the applicability;

[0041] Meanwhile, a plurality of lapping arc openings 14 are formed in the first support arm 7, the second support arm 8 and the third support arm 9. When placing the corrugated pipe, it can be placed in the lapping arc openings 14, thereby increasing the contact area between the two, making the placement more stable. In addition, a first retaining arm 15 is provided at one end of the first support arm 7, the second support arm 8 and the third support arm 9 away from the column 3. The first retaining arm 15 can limit the corrugated pipe and prevent it from falling. At the same time, a second retaining arm 16 is provided between the first support arm 7, the second support arm 8 and the third support arm 9 at positions between two adjacent lapping arc openings 14. The second retaining arm 16 can separate and place two adjacent corrugated pipes, avoiding mutual extrusion deformation and facilitating picking and placing.

[0042] Meanwhile, in order to facilitate the operation of the braking member 13 by the staff and reduce the operation steps, the braking member 13 includes two first pins 17 arranged in parallel. The distance between the two first pins 17 is equal to the distance between the two braking holes 11. At the same time, a connecting member 18 is provided between the two first pins 17. The two first pins 17 are connected into a whole through the connecting member 18. During operation, it only needs to be inserted once when the braking hole 11 and the adjusting hole 12 are concentric.

[0043] Meanwhile, since the length of the third support arm 9 is the largest, the number and weight of the corrugated pipes placed on it are the largest. In order to prevent the third support arm 9 from sagging under the action of the weight, a support column 19 is hinged at the end of the third support arm 9. At the same time, a clamping member 20 is provided on the chassis 1 at the position where the support column 19 is in a vertical state. A second pin 21 is provided between the clamping member 20 and the support column 19.

[0044] During use, first, according to the diameter size of the corrugated pipe, the first support arm 7, the second support arm 8 and the third support arm 9 are slid along the sliding groove 6 in sequence to adjust the distance between the three, and the braking member 13 is used to fix the positions of the first support arm 7, the second support arm 8 and the third support arm 9. Then, in accordance with the weight and diameter sequence of the corrugated pipes, the corrugated pipes with smaller weights are placed on the first support arm 7 and the second support arm 8, and the corrugated pipes are placed in the lapping arc openings 14. The corrugated pipes with larger weights are placed on the third support arm 9. In this way, the purpose of stacking multiple corrugated pipes side by side can be achieved, avoiding additional occupation of space. At the same time, the dependence on power is eliminated during height adjustment, improving the applicability and being more suitable for the actual needs of the factory.

[0045] The above is only the preferred specific embodiment of the present invention, and does not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
