Description

Technical Field

[0001] The utility model belongs to the field of material box equipment, and particularly relates to a bottom-dumping material box for a single-track crane. Background Technique

[0002] At present, single-track cranes are mostly used for material transportation in environments such as roadways or underground. The single-track crane locomotive cooperates with the material box for material transportation. This transportation method mostly requires manual unloading, resulting in a large labor intensity. Or after the material box is hoisted to a designated position, the baffle of the box body is opened to achieve material unloading. However, this method has the following problems:

[0003] 1. When manually opening the bottom baffle of the material box, the bottom baffle is locked under the action of the self-weight of the material, and it is difficult to open manually.

[0004] 2. When using methods such as cylinders and motors to open the baffle of the material box, however, using external power for unloading affects the stability during unloading, and it is inconvenient in underground or roadway environments.

[0005] In view of the above problems, the utility model patent with the patent publication number CN216944529U discloses a self-unloading material box. The material box is composed of two boxes with inclined hoppers installed at the bottom on the left and right. T-shaped sliding seats are arranged in the middle of the two side boxes. The top of the T-shaped sliding seat is symmetrically and rotatably connected with rotating shafts, and the rotating shafts are respectively installed outside the two side boxes. A discharge plate is arranged at the rear of the T-shaped sliding seat. The single-track crane realizes the displacement of the discharge plate on the T-shaped sliding seat by hoisting the lifting lugs at different positions, and opens the two side boxes at a certain angle to achieve automatic unloading. However, due to its complex structure, in the actual application process, the transported materials contain a lot of minerals and sand particles, which easily cause jamming of the chute and the sliding sleeve, resulting in a greatly reduced use effect. And during transportation and unloading, it is necessary to manually change the position of the single-track crane hook, resulting in a greatly reduced transportation efficiency. Summary of the Invention

[0006] The utility model provides a bottom-dumping material box for a single-track crane to solve the problems that the existing self-unloading material box has a complex structure, the transported materials are likely to cause jamming of the chute and the sliding sleeve, etc., affecting the transportation efficiency, and it is difficult for manual operation to open the material box during loading and unloading. The first insertion rod and the second insertion rod are not only simple, convenient and labor-saving to disassemble and assemble, but also effectively avoid the jamming caused by the transported materials falling on the sliding sleeve position. The structure is simple and the operation is convenient.

[0007] In order to achieve the above object, the technical solution of the utility model is:

[0008] A bottom-dumping material box for a single-rail crane, comprising a box body and a bottom plate. The box body includes two first side plates, two second side plates and two inclined plates. The lower ends of the second side plates are fixedly provided with inclined plates. The two ends of the inclined plates are respectively fixedly connected to the two first side plates. The two inclined plates are inclined and their lower ends are close to each other. There is a gap between the lower ends of the two inclined plates to form a discharging opening. When discharging, the materials in the box body fall from the discharging opening.

[0009] The bottom plate is matched with the discharging opening to block the discharging opening. Both ends of the bottom plate are fixedly provided with sliding rods. The sliding rods are located outside the box body. Sliding sleeves are arranged at the front and rear ends of the box body. The sliding rods penetrate up and down and are sleeved in the corresponding sliding sleeves. A locking mechanism is arranged on the sliding sleeves to fix the sliding rods. The effective blocking of the discharging opening by the bottom plate is realized by fixing the sliding rods.

[0010] Preferably, a plurality of legs are fixedly arranged on the outer sides of the upper ends of the inclined plates, and a plurality of lifting lugs are fixedly arranged on the upper end of the box body. The legs ensure that the material box lands on the receiving box body to be loaded, and the lifting lugs are used to cooperate with the single-rail crane.

[0011] Preferably, the bottom plate is in the shape of a triangular prism and is located between the lower ends of the two inclined plates. Openings are arranged at the lower ends of the first side plates. The openings are matched with the bottom plate. When the box body is lifted and separated from the bottom plate for discharging, the bottom plate can realize the function of guiding materials.

[0012] Preferably, the locking mechanism includes a jack and a first insertion rod. Jacks are correspondingly arranged on the sliding sleeve and the sliding rod. The first insertion rod is inserted into the jack. A limiting mechanism is arranged on the sliding sleeve to limit the first insertion rod. The fixing of the sliding rod is realized by the first insertion rod.

[0013] Preferably, the limiting mechanism includes an insertion ring and a second insertion rod. The insertion ring is fixedly arranged on the sliding sleeve. A limiting hole corresponding to the insertion ring up and down is arranged at the end of the first insertion rod.

[0014] Preferably, protective covers are fixedly arranged at both ends of the box body. The protective covers are located above the sliding sleeves and cover the outer sides of the upper ends of the sliding rods. The protective covers prevent materials from falling between the sliding rods and the sliding sleeves.

[0015] Preferably, a cross bar is fixedly arranged at the upper end of the sliding rod to limit the sliding rod.

[0016] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0017] 1. By arranging the split box body and the bottom plate, when discharging the material box, first disconnect the fixation between the box body and the bottom plate, and then lift the box body. The materials fall from the discharging opening to realize discharging.

[0018] 2. When the material box of the present utility model discharges materials, the bottom plate stays above the lower receiving box body, diverting the falling materials, making the material falling more uniform.

[0019] 3. The present utility model realizes the guiding, fixing or releasing of the bottom plate through the cooperation of the sliding sleeves and the first inserting rods arranged at both ends of the box body. Moreover, the fixing and releasing of the bottom plate are both carried out when the bottom plate and the box body are both on the ground or on the receiving box body, effectively avoiding the influence of the self-weight of the materials on the opening and closing of the bottom plate, reducing the difficulty of manually opening the self-unloading box body, and improving work efficiency.

[0020] 4. The present utility model avoids the separation of the bottom plate from the box body by setting a cross bar. Then, after the discharging is completed, the box body can be lowered to fix the bottom plate and the box body, avoiding the dislocation of the two and affecting the loading and unloading.

[0021] 5. The present utility model limits the first inserting rod through the second inserting rod to avoid the first inserting rod slipping along the horizontal direction, resulting in the opening of the material discharging port during the transportation of the box body, ensuring the smooth progress and safety of the material transportation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0029] As Figures 1 to 5As shown in the figure, this embodiment provides a bottom-dumping material box for a single-rail crane, which includes a box body 1 and a bottom plate 2. The box body 1 includes two first side plates, two second side plates, and two inclined plates 3. The two first side plates are arranged oppositely, and the two second side plates are arranged oppositely. The lower ends of the second side plates are fixedly provided with inclined plates 3. The two ends of the inclined plates 3 are respectively fixedly connected to the two first side plates. The two inclined plates 3 are inclined and their lower ends are close to each other. There is a gap between the lower ends of the two inclined plates 3 to form a discharge port 4. That is, the lower end of the box body 1 cooperates with the inclined plates 3 to form a funnel-shaped structure. The bottom plate 2 is matched with the discharge port 4 to block the discharge port 4, so as to realize the accommodation of materials in the material box 1. A plurality of lifting lugs 8 are fixedly arranged at the upper end of the box body 1. The materials are loaded in the box body 1, and the lifting is realized by the cooperation of the single-rail crane and the lifting lugs 8. A plurality of supporting legs 7 are fixedly arranged on the outer side of the upper end of the inclined plate 3 for supporting the box body 1.

[0030] Both ends of the bottom plate 2 are fixedly provided with sliding rods 5. The sliding rods 5 are located outside the box body 1. Sliding sleeves 6 are arranged at the front and rear ends of the box body 1. The sliding rods 5 penetrate up and down and are sleeved in the corresponding sliding sleeves 6. During unloading, the box body 1 and the bottom plate 2 are jointly lifted to the upper part of the receiving box body at the designated position. The supporting legs 7 fall on the outer eaves of the upper end of the lower receiving box body. The bottom plate 2 is supported at the middle parts of both ends of the lower receiving box body. A locking mechanism is arranged on the sliding sleeve 6 to fix the sliding rod 5, ensuring that during the process of lifting the box body 1, the bottom plate 2 is fixed under the box body 1. The bottom plate 2 is in the shape of a triangular prism and is located between the lower ends of the two inclined plates 3. Openings are provided at the lower ends of the first side plates, and the openings are matched with the bottom plate 2. After the box body 1 is placed, the locking mechanism is opened, so that the sliding rod 6 and the sliding sleeve 5 can perform up and down sliding movements. Then the box body 1 is lifted, and the box body 1 is separated from the bottom plate 2. The up and down correspondence between the box body 1 and the bottom plate 2 is ensured through the sliding sleeve 6. A cross bar 15 is fixedly arranged at the upper end of the sliding rod 5. The cross bar 15 is used to prevent the box body 1 from being completely separated from the bottom plate 2, which is convenient for the reset of the relative positions of the box body 1 and the bottom plate 2 after unloading. As the box body 1 continues to be lifted, the discharge port 4 is opened, and the materials fall from the discharge port 4, are separated to both sides through the bottom plate 2 and fall into the lower receiving box body to complete the unloading. After the unloading is completed, the single-rail crane lowers the box body 1, the bottom plate 2 comes into contact with and cooperates with the box body 1 again, and the relative fixation of the bottom plate 2 and the box body 1 is completed through the locking mechanism, and then the next material transportation can be carried out.

[0031] The locking mechanism includes a jack 9 and a first plug rod 10. Jacks 9 are correspondingly opened on the sliding sleeve 6 and the sliding rod 5. That is, when the two ends of the bottom plate 2 are tightly attached to the openings at the lower ends of the first side plates in a corresponding manner, the two jacks 9 correspond to each other. The first plug rod 10 is inserted into the jack 9 to realize the relative fixation of the bottom plate 2 and the box body 1, and thus realize the smooth transportation of materials.

[0032] Since the first insertion rod 10 is horizontally inserted into the corresponding insertion hole 9, in order to prevent the first insertion rod 10 from slipping off during the transportation of materials, a limiting mechanism is provided on the sliding sleeve 6 to limit the first insertion rod 10. The limiting mechanism includes an insertion ring 11 and a second insertion rod 12. An insertion ring 11 is fixedly arranged on the sliding sleeve 6. A limiting hole 13 corresponding to the insertion ring 11 is arranged at the end of the first insertion rod 10. The second insertion rod 12 is inserted into the limiting holes 13 and the insertion ring 11 corresponding up and down. The second insertion rod 12 is used to limit and fix the first insertion rod 10. The second insertion rod 12 can be connected to the sliding sleeve 6 or the box body 1 through ropes, chains, etc.

[0033] Protective covers 14 are fixedly arranged at both ends of the box body 1. The protective covers 14 are located above the sliding sleeve 6 and cover the outer sides of the upper ends of the sliding rods 5. Through the arrangement of the protective covers 14, when loading materials into the box body 1, it is avoided that the materials splash and fall on the positions of the sliding rods 5 and the sliding sleeve, resulting in jamming problems and affecting the work progress.

[0034] During use, first, the relative positions of the box body 1 and the bottom plate 2 are fixed through the locking mechanism and the limiting mechanism. Then, materials are loaded into the box body 1. Then, the box body 1 is lifted by a monorail crane by hanging the lifting lug 7, and the box body 1 is hoisted above the upper outer eaves of the receiving box body at the designated position. Then, it is lowered so that the supporting legs 7 fall on the upper outer eaves of the lower receiving box body. The bottom plate 2 is supported at the middle parts of both ends of the lower receiving box body. After the box body 1 is placed, the second insertion rod 12 and the first insertion rod 10 are pulled out in sequence to release the fixation of the bottom plate 2, so that the sliding rod 6 and the sliding sleeve 5 can slide relatively up and down. Then, the box body 1 is lifted. The box body 1 and the bottom plate 2 are separated. The cross bar 15 is used to prevent the two from completely separating. As the box body 1 is continuously lifted, the feeding port 4 is opened, and the materials fall from the feeding port 4, are separated to both sides through the bottom plate 2 and fall into the lower receiving box body to complete the discharging. After the discharging is completed, the monorail crane lowers the box body 1. The bottom plate 2 and the box body 1 come into contact and cooperate again. The first insertion rod 10 and the second insertion rod 12 are inserted into the corresponding positions to reset in sequence. Then, the box body 1 can be hoisted to the loading position for the next material transportation process.

[0035] The above embodiments are only the preferred embodiments of the present invention, and do not limit the implementation scope of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
