Description

Technical Field

[0001] The utility model relates to the field of material unloading mechanisms, in particular to a platform door opening device which is convenient for unloading materials with a long rod. Background Art

[0002] Some long rods and round rods need to be drilled during processing. A Chinese utility model patent with the announcement number CNC217701472U discloses a feeding mechanism of a round rod drilling machine, which is combined with an inclined storage box and a material dropping mechanism. The baffle swings to make the round rod drop under the action of gravity. The round rod on the material dropping chute enters the drilling machine under the push of the baffle to perform drilling operation.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the baffle is deflected under the action of the push rod motor, so that the round rod is between the two baffles, so as to block and discharge the round rod. Since the baffle is deflected upward to discharge the round rod below, the multiple round rods on the left side of the baffle will also roll downward under the action of gravity. When the baffle is used to cover another round rod for discharge, the round rod on its left side needs to be moved upward by a certain distance as a whole. When there are many round rods, the overall weight is large, and a great force is required to move it to the left, and even the back will get stuck. For this reason, we designed a platform door opening device that is convenient for long rod discharge. Utility Model Content

[0004] In order to solve the technical problem of troublesome unloading of long poles, the utility model provides a platform door opening device which is convenient for unloading of long poles.

[0005] The utility model is implemented by the following technical scheme: a platform door opening device which is convenient for unloading long rods, comprising a storage frame, a unloading port being integrally formed at the left end of the storage frame, a plurality of movable holes in a strip-shaped structure being opened above the unloading port, two fixed plates symmetrically arranged front and back being welded above the storage frame, a lifting cylinder 2 being fixed on the two fixed plates, a lifting plate 2 being installed on the push rod of the lifting cylinder 2, a plurality of partition door strips distributed at equal intervals being arranged at the lower end of the lifting plate 2, a lifting cylinder 1 being respectively provided on the two fixed plates for sliding left and right, a lifting plate 1 being installed on the push rod of the lifting cylinder 1, a plurality of partition door strips distributed at equal intervals being arranged at the lower end of the lifting plate 1, the partition door strips and the partition door strips both slide up and down through the movable holes and are placed inside the unloading port.

[0006] As a further improvement of the above solution, the feed opening is welded at an angle below the left end of the storage frame, and the feed opening is designed to be inclined toward the lower left, so that the long rod inside the storage frame can slide out to the left along the feed opening under its own gravity.

[0007] As a further improvement of the above scheme, a movable sliding hole with a strip-shaped structure is opened above the fixed plate, and a mounting slide plate is arranged above the fixed plate for sliding left and right. The lifting cylinder 1 is installed on the mounting slide plate, and the push rod of the lifting cylinder 1 passes through the movable sliding hole and is placed under the fixed plate. The positions of the lifting cylinder 1 and the lifting plate 1 can be adjusted as needed, so that it is suitable for long rods with different outer diameters.

[0008] As a further improvement of the above scheme, a strip hole is opened on the inner side of the upper part of the fixing plate, and a screw is welded under the mounting slide plate. The screw passes through the strip hole and is placed under the fixing plate, and a nut is threadedly connected to the screw. The lifting cylinder 1 can slide left and right under the action of the mounting slide plate and is fixed by the nut, so that the lifting cylinder 1 can be quickly adjusted and fixed.

[0009] As a further improvement of the above scheme, the width of the blocking door strip and the dividing door strip is smaller than the width of the movable hole, and the cross-section of the bottom end of the blocking door strip and the dividing door strip is a semicircular structure. When the bottom end of the blocking door strip and the dividing door strip contacts the outer ring surface of the long rod, it will not cause scratches on its surface.

[0010] As a further improvement of the above scheme, two symmetrically arranged adjustment sliding holes are provided on the left side surface of the storage frame, and a guide plate is provided on the left side of the storage frame for sliding up and down. A locking screw is provided on the guide plate, which passes through the guide plate and is placed outside the guide plate and is threadedly connected with a locking nut. The guide plate can move up and down, so that there is a certain distance between the top of the lowest long rod and the bottom of the guide plate, so that multiple long rods will not accumulate in the discharge port, thereby avoiding blockage.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a blocking door strip and a separating door strip at the left end of the storage frame, and they can move up and down under the action of the lifting cylinder 1 and the lifting cylinder 2, so as to block a plurality of long rods and separate the long rod at the far left end from the other long rods, so as to facilitate the separate unloading of the long rods, and the operation is simple and will not cause blockage;

[0024] The feed opening 11 is welded obliquely at the lower left end of the storage frame 1 , and is designed to be inclined toward the lower left, so that the long rod inside the storage frame 1 can slide out toward the left along the feed opening 11 under its own gravity.

[0025] A movable sliding hole 31 with a strip-shaped structure is provided above the fixed plate 3, and a mounting slide plate 41 is provided above the fixed plate 3 for sliding left and right. The lifting cylinder 4 is installed on the mounting slide plate 41, and the push rod of the lifting cylinder 4 passes through the movable sliding hole 31 and is placed under the fixed plate 3. The positions of the lifting cylinder 4 and the lifting plate 2 can be adjusted as needed, so that it is suitable for long rods with various outer diameters.

[0026] A strip hole is opened on the inner side above the fixing plate 3, and a screw is welded under the mounting slide 41. The screw passes through the strip hole and is placed under the fixing plate 3, and a nut is threadedly connected to the screw. The lifting cylinder 4 can slide left and right under the action of the mounting slide 41 and is fixed by the nut, so that the lifting cylinder 4 can be quickly adjusted and fixed.

[0027] The width of the partition door strip 21 and the partition door strip 61 are both smaller than the width of the moving hole 111, and the cross-section of the bottom end of the partition door strip 21 and the partition door strip 61 is a semicircular structure. When the bottom end of the partition door strip 21 and the partition door strip 61 contacts the outer ring surface of the long rod, it will not cause scratches on its surface.

[0028] Two symmetrically arranged adjustment slide holes are provided on the left side surface of the storage frame 1. A guide plate 7 is provided on the left side of the storage frame 1 for sliding up and down. A locking screw is provided on the guide plate 7.

The guide plate 7 can move up and down, so that there is a certain distance between the top of the lowest long rod and the bottom of the guide plate 7, so that multiple long rods will not accumulate in the discharge port 11, thereby avoiding blockage.

[0029] The implementation principle of a platform door opening device for facilitating long rod unloading in the embodiment of the present application is as follows: in actual use, firstly, the distance between the partition door strip 21 and the partition door strip 61 is adjusted according to the size of the long rod. Specifically, the lifting cylinder 1 4 is turned on to make the partition door strip 21 descend, and then the two long rods are placed in the storage frame 1. The long rods will slide downward under the action of their own gravity and contact the partition door strip 21. The nuts are loosened, and the two lifting cylinders 1 4 are moved to the right at the same time. The long rod moves together with it until the long rod on the right is on the right side of the partition door strip 61. At this time, the lifting cylinder 2 5 is turned on again. And make the partition door strip 61 go down, make the bottom end of the partition door strip 61 contact with the upper left surface of the outer ring of the long rod on the right side, and then tighten the nut. When it is necessary to unload materials, the push rod of the lifting cylinder 1 4 makes the partition door strip 21 move up, and a long rod on its left side can fall down, and then the push rod of the lifting cylinder 1 4 moves down to make the partition door strip 21 return to its original position, the push rod of the lifting cylinder 2 5 moves up, and another long rod contacts the partition door strip 61, and the push rod of the lifting cylinder 2 5 makes the partition door strip 61 move down to return to its original position, and the second to last long rod is limited again, and the above operation is repeated to carry out the unloading operation continuously;

[0030] By arranging a blocking door strip 21 and a partition door strip 61 at the left end of the storage frame 1, and they can move up and down under the action of the lifting cylinder 1 4 and the lifting cylinder 2 5, a plurality of long rods can be blocked, and the long rod at the far left end can be separated from the other long rods, so that the long rods can be unloaded separately, the operation is simple, and no blockage will be caused;

[0031] By sliding the lifting cylinder 4 left and right on the fixed plate 3, the distance between the partition door strip 21 and the partition door strip 61 can be adjusted, which is suitable for long rods of various sizes and improves practicality.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
