Description

Technical Field

[0001] The invention relates to the field of material transportation, and in particular to a pallet material transportation device for railway construction. Background Art

[0002] Railway construction pallets are a commonly used tool in the process of material transportation. In order to save space and facilitate use, pallets need to be stacked after use. Traditional stacking methods generally use manual stacking or forklift stacking. Manual or forklift stacking has problems such as incomplete stacking, easy skewness, inconvenient access, and safety hazards. In addition, palletizing in the above way is not convenient for taking the pallets, especially when using hydraulic forklifts to take the pallets, it is necessary to take the pallets down by other means before using them, which affects production efficiency. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a railway construction pallet material conveying device which can automatically stack pallets neatly, facilitate pallet retrieval and has no safety risks.

[0004] The purpose of the present invention is to be achieved through the following technical solutions: A railway construction pallet material conveying equipment comprises a frame, two wedges are slidably connected to the two sides of the frame, a No. 1 lead screw is connected to the two wedges, the No. 1 lead screw is rotatably connected to the frame, a group of positioning devices are respectively connected to the left and right sides of the frame, each positioning device is rotatably connected to the frame, two releasing devices are respectively slidably connected to the left and right sides of the frame, each releasing device is connected to a No. 2 lead screw, the No. 2 lead screw is connected to the frame, and when the pallet is taken, the releasing devices are sequentially connected to a group of positioning devices on the same side; two symmetrical wedges are arranged on both sides of the frame, the wedges are structures with inclined surfaces inside, two bottom slide grooves on the left and right sides of the frame are respectively slidably connected to the two wedge slide rods on the outside of the wedges, and the wedge screw holes on the rear sides of the two wedges are respectively threadedly connected to the screws on both sides of the No. 1 lead screw The threads on both sides of the No. 1 lead screw have opposite rotation directions, the No. 1 lead screw is rotatably connected to the bearing seat in the middle of the rear side of the frame, one side of the No. 1 lead screw is connected to the output shaft of the No. 1 motor, and the No. 1 motor is fixed on the frame; the positioning device includes a No. 1 shaft, and two positioning seats are fixedly connected to the No. 1 shaft, and the positioning seat hole at the lower part of each positioning seat is fixedly connected to the No. 1 shaft, and a positioning seat groove is provided in the middle of the positioning seat, a partition is provided in the middle of the positioning seat groove, and a partition hole is provided in the middle of the partition, and a support block is provided on the inner side of each positioning seat, and the support block is slidably connected to the inner side of the positioning seat groove, and the support block rod on the outer side of the support block is slidably connected to the partition hole, and two springs are provided between the positioning seat and the support block, and the two springs are sleeved on the outer side of the support block rod, and the two sides of the two springs respectively press against the two sides of the partition and the two sides of the support block rod on both sides.

[0005] Two symmetrical columns are provided on both sides of the frame, a group of column inner holes are provided on the inner sides of the two columns on the left and right sides, and a column outer hole is provided on the upper side of the outer side of each column inner hole. A group of No. 2 shafts are connected to the two columns on the left and right sides respectively, and each No. 2 shaft is fixed in the corresponding column outer holes on the two columns on the same side. A group of positioning devices are connected to the two columns on the left and right sides respectively, and the No. 1 shaft in the middle of each positioning device is rotatably connected to the corresponding column inner holes on the two columns on the same side, and the upper right side of each No. 1 shaft contacts the corresponding lower part of the No. 2 shaft.

[0006] The release device includes a release seat and a release block. The fertilizing seat shaft outside the release seat is rotatably connected to the release block. The release block is a triangular wedge structure. The release block inclined surface outside the release block faces the outside of the upper frame. The stop plate at the bottom of the fertilizing seat shaft corresponds to a right-angled side of the release block.

[0007] Beneficial effect: The use of this device is divided into stacking mode and retrieval mode. In the stacking mode, the forklift delivers the pallet to the middle of the rack, the wedges fall onto the wedge bottom plates of the wedges on both sides, the No. 1 motor is started, and the No. 1 motor rotates to drive the wedges on both sides to move synchronously to the middle, and the pallet moves upward under the action of the inclined surface inside the wedges, and the wedges on both sides position the pallet between the two wedges and lift the pallet at the same time to prevent the pallet from shifting and ensure that both sides of the pallet can be held up by the positioning device. After the pallet is raised to a certain distance, the two sides of the pallet will push up the two positioning devices on each side, and the pallet will push up the positioning device and pass After passing the positioning device, motor No. 1 rotates in the opposite direction and the wedge blocks on both sides are reset. After the wedge blocks on both sides are reset, the pallet falls down with the wedge blocks. After the pallet falls down, it will be supported by the inner side of each support block. At this time, the outer side of the positioning device is blocked by the corresponding No. 2 axis. Each positioning device remains horizontal. At this time, the pallet is positioned on the upper part of the positioning devices on both sides. When there is another pallet next time, the above process is repeated. When the lowermost pallet is lifted, the upper pallet will be lifted together. Each pallet will pass the corresponding positioning device. When the pallet descends, each support block will also support the corresponding pallet, thus achieving the purpose of pallet stacking.

[0008] When the present invention is in the taking mode, when the No. 2 motor rotates, it drives the corresponding No. 2 screw and the synchronous wheel to rotate. The rotation of the synchronous wheel drives the synchronous belt to rotate around the four No. 2 screws. The synchronous wheel and the synchronous belt make the four No. 2 screws keep in a synchronous rotation state. When the four No. 2 screws rotate, they drive the corresponding releasing devices to slide along the slide groove. When the releasing device moves upward, the inclined surface of the releasing block will slide over the inclined surface of the square frame on the outside of each square frame from bottom to top in sequence. When the inclined surface of the releasing block slides over the inclined surface of the square frame, the inclined surface of the releasing block pushes the supporting block to the outside of the frame. When the supporting block is pushed to the outside, the supporting block will be pulled out from the lower part of the corresponding pallet, and the pallet that has lost its support will fall. During the process of the releasing device rising from the bottom, each pallet will fall down, and the lowest pallet will fall onto the bottom plate of the wedge block at the bottom, and the upper pallet will fall onto the positioning device at the bottom in sequence. At this time, the forklift can take out the lowest pallet.

[0009] The wedge block of the present invention has a structure with an inclined surface on the inner side. The inclined surface on the inner side of the wedge block not only has the function of positioning the pallet, but also has the function of lifting the pallet, ensuring that the pallet is in the center of the frame and ensuring that the positioning devices on both sides can hold up the pallet, thereby achieving the purpose of stacking. The skewness of the pallet can easily cause the problem that the positioning device cannot hold up the pallet and causes a group of pallets to skew, thereby causing safety problems. A group of pallets is in the middle of the frame, and the pallets will not topple over due to external touch, further improving safety. The four releasing devices are synchronously lifted under the drive of a group of No. 2 lead screws, so that a group of pallets fall one by one from bottom to top, which not only achieves the purpose of taking the pallets one by one, but also prevents damage to the pallets caused by the simultaneous falling of the pallets.

[0023] refer to Figure 5 , 6Two symmetrical wedge blocks 120 are provided on both sides of the frame 110. The wedge blocks 120 are structures with inclined surfaces inside. The two bottom slide grooves 118 on the left and right sides of the frame 110 are respectively slidably connected to the two wedge block slide rods 122 on the outside of the wedge blocks 120. The wedge block screw holes 124 on the rear sides of the two wedge blocks 120 are respectively threadedly connected to the threads on both sides of the No. 1 lead screw 130. The rotation directions of the threads on both sides of the No. 1 lead screw 130 are opposite. The No. 1 lead screw 130 is rotatably connected to the bearing seat 119 in the middle of the rear side of the frame 110. One side of the No. 1 lead screw 130 is connected to the output shaft of the No. 1 motor 140, and the No. 1 motor 140 is fixed on the frame 110. When the pallet 210 is sent into the middle groove 111 in the middle of the frame 110, the wedge block 120 falls onto the wedge block bottom plate 121 inside the wedge blocks 120 on both sides, and the No. 1 motor 140 is started. The No. 1 motor 140 rotates to drive the wedge blocks 120 on both sides to move synchronously to the middle. The pallet 210 is positioned in the middle of the middle groove 111 and moves upward under the action of the inclined surface inside the wedge block 120. The wedge block 120 plays a dual role of positioning the pallet 210 and lifting the pallet 210. The synchronously moving wedge block 120 positions the pallet 210 in the middle of the middle groove 111, ensuring that both sides of the pallet 210 can be lifted by the positioning device 300, and the inclined surface of the wedge block 120 lifts the pallet 210 at the same time, ensuring that the pallet 210 can be positioned on each positioning device 300 in sequence.

[0024] refer to Figures 7 to 9 The positioning device 300 includes a No. 1 shaft 340, on which two positioning seats 310 are fixedly connected, a positioning seat hole 314 at the lower part of each positioning seat 310 is fixedly connected to the No. 1 shaft 340, a positioning seat groove 311 is provided in the middle of the positioning seat 310, a partition 312 is provided in the middle of the positioning seat groove 311, and a partition hole 313 is provided in the middle of the partition 312, and a support block 320 is provided on the inner side of each positioning seat 310, the support block 320 is slidably connected to the inner side of the positioning seat groove 311, and a support block rod 322 on the outer side of the support block 320 is slidably connected to the partition hole 313, two springs 330 are provided between the positioning seat 310 and the support block 320, the two springs 330 are sleeved on the outer side of the support block rod 322, and the two sides of the two springs 330 respectively press against the two sides of the partition 312 and the two sides of the support block rod 322 on both sides.

[0025] refer to Figure 3 , 5Two symmetrical columns 112 are respectively provided on both sides of the frame 110, a group of column inner holes 113 are provided on the inner sides of the two columns 112 on the left and right sides, and a column outer hole 114 is provided on the upper side of the outer side of each column inner hole 113. A group of No. 2 shafts 190 are respectively connected to the two columns 112 on the left and right sides, and each No. 2 shaft 190 is fixed in the corresponding column outer hole 114 on the two columns 112 on the same side. A group of positioning devices 300 are respectively connected to the two columns 112 on the left and right sides, and the No. 1 shaft 340 in the middle of each positioning device 300 is rotatably connected to the corresponding column inner hole 113 on the two columns 112 on the same side, and the upper right part of each No. 1 shaft 340 contacts the lower part of the corresponding No. 2 shaft 190. After the pallet 210 is lifted, when the pallet 210 rises to a certain distance, the two sides of the pallet 210 will push up the two positioning devices 300 on each side. After the pallet 210 pushes up the positioning devices 300 and passes over the positioning devices 300, the first motor 140 rotates in the opposite direction, and the wedge blocks 120 on both sides are reset. After the wedge blocks 120 on both sides are reset, the pallet 210 falls down with the wedge blocks 120. After the pallet 210 falls, it will be supported by the inner side of each support block 320. At this time, the outer side of the positioning device 300 is supported by the corresponding The No. 2 axis 190 is blocked, and each positioning device 300 remains in a horizontal state. At this time, the pallet 210 is positioned on the upper part of the positioning devices 300 on both sides. When there is another pallet 210 next time, the above process is repeated. When the lowermost pallet 210 is lifted, the upper pallet 210 will be lifted together. Each pallet 210 will pass over the corresponding positioning device 300. When the pallet 210 descends, each support block 320 will also support the corresponding pallet 210, thereby achieving the purpose of stacking the pallets 210.

[0026] refer to Fig.10 , 11 The release device 400 includes a release seat 410 and a release block 420. The fertilizer seat shaft 411 outside the release seat 410 is rotatably connected to the release block 420. The release block 420 is a triangular wedge structure. The release block inclined surface 421 outside the release block 420 faces the outside of the upper frame 110. The stop plate 412 at the bottom of the fertilizer seat shaft 411 corresponds to a right-angled side of the release block 420.

[0027] refer to Figure 3 Two front-to-back symmetrical slides 115 are respectively provided on the left and right sides of the middle groove 111 in the middle of the frame 110, and a slide groove 116 is provided on the inner side of each slide 115. The upper and lower parts of each slide 115 are provided with a slide hole 117 that penetrates the frame 110. A No. 2 lead screw 150 is rotatably connected in the middle of each slide hole 117, and a synchronous wheel 160 is fixedly connected to the upper part of each No. 2 lead screw 150. The outer sides of the four synchronous wheels 160 are rotatably connected to the synchronous belt 170, and the upper part of one of the No. 2 lead screws 150 is fixedly connected to the No. 2 motor 180, and the No. 2 motor 180 is fixed to the upper part of the corresponding slide 115.

[0028] refer to Figure 1 , 3 5. A release device 400 is provided in the slide groove 116 on the inner side of each slide seat 115. The block 413 on the inner side of each release seat 410 is slidably connected to the corresponding slide groove 116. The block screw hole 414 in the middle of each block 413 is threadedly connected to the corresponding No. 2 screw 150.

[0029] refer to Figure 1 , 3 5. The square frame 323 outside the supporting block 320 passes through the corresponding sliding seat 115. When the releasing device 400 moves upward, the releasing block inclined surface 421 of the releasing block 420 will slide over the square frame inclined surface 324 outside each square frame 323 in turn. When the No. 2 motor 180 rotates, it drives the corresponding No. 2 lead screw 150 and synchronous wheel 160 to rotate. The rotation of the synchronous wheel 160 drives the synchronous belt 170 to rotate around the four No. 2 lead screws 150. The synchronous wheel 160 and the synchronous belt 170 keep the four No. 2 lead screws 150 in a synchronous rotation state. When the four No. 2 lead screws 150 rotate, they drive the corresponding release device 400 to slide along the slide groove 116. When the release device 400 moves upward, the release block slope 421 will slide over the square frame slope 324 on the outside of each square frame 323 from bottom to top. When the release block slope 421 slides over the square frame slope 324, the release block slope 421 pushes the support block 320 to the outside of the frame 110. When the support block 320 is pushed outward, the support block 320 will slide from the corresponding pallet 2 10 is pulled out from the bottom, and the pallet 210 that loses its support will fall down. After the release block slope 421 slides over the square frame slope 324, the spring 330 resets the support block 320. During the process of the release device 400 rising from the bottom, each pallet 210 falls down one by one, and the lowest pallet 210 falls on the lower wedge block bottom plate 121, and the upper pallets 210 will fall on the lower positioning device 300 in turn. At this time, the forklift can take out the lowest pallet 210, and the release block 420 can only rotate counterclockwise. When the release block 420 rotates clockwise, it is stopped by the stop plate 412 group, so that the release device 400 can allow the pallets 210 to fall down one by one when it moves upward. When the release device 400 is reset, the release block 420 rotates without affecting the pallet 210.

[0030] An operating method of a railway construction pallet material conveying equipment comprises the following steps: the use of the device is divided into a stacking mode and a retrieval mode. In the stacking mode, a forklift is used to deliver a pallet 210 to the middle of a frame 110, and wedge blocks 120 fall onto wedge block bottom plates 121 of the wedge blocks 120 on both sides. Motor No. 140 is started, and the rotation of motor No. 140 drives the wedge blocks 120 on both sides to move synchronously toward the middle. The pallet 210 moves upward under the action of the inclined surfaces on the inner sides of the wedge blocks 120. The wedge blocks 120 on both sides position the pallet 210 between the two wedge blocks 120 and lift the pallet 210 at the same time to prevent the pallet 210 from shifting and ensure that the two sides of the pallet 210 can be lifted by the positioning devices 300. After the pallet 210 is raised to a certain distance, the two sides of the pallet 210 will push up the two positioning devices 300 on each side, and the pallet 210 will After the positioning device 300 is lifted up and passes over the positioning device 300, the No. 1 motor 140 rotates in the opposite direction, and the wedge blocks 120 on both sides are reset. After the wedge blocks 120 on both sides are reset, the pallet 210 falls down with the wedge blocks 120. After the pallet 210 falls, it will be supported by the inner side of each support block 320. At this time, the outer side of the positioning device 300 is blocked by the corresponding No. 2 shaft 190, and each positioning device 300 remains in a horizontal state. At this time, the pallet 210 is positioned on the upper part of the positioning devices 300 on both sides. When there is another pallet 210 next time, the above process is repeated. When the lowermost pallet 210 is lifted, it will drive the upper pallet 210 to be lifted together. Each pallet 210 will pass the corresponding positioning device 300, and when the pallet 210 descends, each support block 320 will also support the corresponding pallet 210, thereby achieving the purpose of stacking the pallets 210.

[0031] In the access mode, when the No. 2 motor 180 rotates, it drives the corresponding No. 2 lead screw 150 and the synchronous wheel 160 to rotate. The rotation of the synchronous wheel 160 drives the synchronous belt 170 to rotate around the four No. 2 lead screws 150. The synchronous wheel 160 and the synchronous belt 170 keep the four No. 2 lead screws 150 in a synchronous rotation state. When the four No. 2 lead screws 150 rotate, they drive the corresponding release device 400 to slide along the slide groove 116. When the release device 400 moves upward, the release block inclined surface 421 will slide over the outer side of each box 323 from bottom to top in turn, and the release block When the inclined surface 421 slides over the square frame inclined surface 324, the release block inclined surface 421 pushes the support block 320 to the outside of the frame 110. When the support block 320 is pushed to the outside, the support block 320 will be pulled out from the bottom of the corresponding pallet 210, and the pallet 210 that has lost its support will fall down. During the process of the release device 400 rising from the bottom, each pallet 210 will fall down, and the lowest pallet 210 will fall onto the lower wedge block bottom plate 121, and the upper pallets 210 will fall onto the lower positioning device 300 in turn. At this time, the forklift can take out the lowest pallet 210.

[0032] The wedge block 120 is a structure with an inclined surface on the inner side. The inclined surface on the inner side of the wedge block 120 not only has the function of positioning the pallet 210, but also has the function of lifting the pallet 210, ensuring that the pallet 210 is in the center of the frame 110, ensuring that the positioning devices 300 on both sides can hold up the pallet 210 to achieve the purpose of stacking. The skewness of the pallet 210 can easily cause the positioning device 300 to be unable to hold up the pallet 210 and cause a group of pallets 210 to skew, thereby causing safety problems. A group of pallets 210 is in the middle of the frame 110, and the pallets 210 will not fall over due to external touch, further improving safety. The four release devices 400 are synchronously lifted under the drive of a group of No. 2 screws 150, so that a group of pallets 210 falls one by one from bottom to top, which not only achieves the purpose of taking the pallets 210 one by one, but also prevents the damage to the pallets 210 caused by the simultaneous falling of the pallets 210.
