Description

Technical Field

[0001] The invention relates to the technical field of steel casting conveying, in particular to a steel casting oblique conveying device with an anti-slip protection structure. Background Art

[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron. They are prone to defects such as porosity and inaccurate angle positioning during the casting process. Steel castings have different shapes, among which plate and tubular castings are the most commonly used. Since steel castings are made of metal, they are usually transported to a high operating table for fine processing using contact clamps or conveyor belts during processing.

[0003] According to a device for obliquely conveying aluminum strip waste from low to high with publication number CN203754075U, a boosting mechanism with a paddle is added above the belt conveyor mechanism to give a boosting force to the conveyed items on the belt conveyor mechanism, so that the conveyed items can be conveyed from low to high in an oblique manner;

[0004] However, the above patent content uses a conveyor belt to transport materials at an angle upward. In actual operation, this conveying method is prone to cause the conveyed items to gradually tilt and shift. It is also easy to cause the items to slide in the opposite direction and slip off because the conveyor belt has no special limiting structure, which greatly affects the efficiency of the oblique upward transmission of materials.

[0005] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to feed multiple groups of superimposed steel casting plates layer by layer and obliquely upward, which not only reduces complicated processes such as lifting and transportation, but also facilitates the control of the feeding interval of a single group of steel casting plates, reduces collision damage between steel casting plates, and improves the oblique feeding efficiency of steel castings. At the same time, when the steel casting plates are fed obliquely upward, the reverse limitation of the steel casting plates is strengthened to prevent the steel casting plates from slipping in the reverse direction when being fed obliquely upward, thereby further improving the transmission efficiency of the steel casting plates.

[0014] Furthermore, a concave card seat is fixedly installed at an equal distance on the top surface of the transmission long plate, and an L-shaped abutment frame is hingedly connected to the inclined structure at the top notch inside the concave card seat, and the top surface of the L-shaped abutment frame is flush with the bottom surface of the half-card frame.

[0015] Furthermore, a second motor is provided on the top frame of the conveying bottom frame and between the front and rear two groups of horizontal sliding frames, and a double-angle turntable is provided at the top output end of the second motor, and the front and rear ends of the double-angle turntable are respectively hinged to the corresponding horizontal sliding frames through hinge rods.

[0016] Furthermore, several groups of anti-slip components are arranged on the top surfaces of the two groups of conveying bottom frames, and the several groups of anti-slip components are respectively arranged on the top surfaces of the front and rear groups of inclined sliding frames.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention cooperates with the transverse sliding frame, the oblique sliding frame and the guiding mechanism, and several groups of L-shaped abutment frames are driven with the transmission long plate. The L-shaped abutment frame at the rear end of the transmission long plate first moves toward the steel cast plate superimposed on the bottom layer, and the top frame body of this group of L-shaped abutment frames is abutted and deflected into a V-shaped structure until the L-shaped abutment frame passes over the bottom steel cast plate, and the L-shaped abutment frame flips back to its original position until the teeth on the outside of the toothed disc pass over the tooth groove group, and the transmission long plate loses the transmission force and resets, and the transmission long plate pulls several groups of L-shaped abutment frames to move obliquely upward, and the L-shaped abutment frame located on the side of the bottom steel cast plate uses the side frame edge to push the bottom steel cast plate to move, at this time, the bottom steel cast plate is separated from the superimposed steel cast plate group and moves obliquely upward, and the steel cast plate transferred by a single group moves to the adjacent L-shaped abutment frame, and then the above-mentioned transmission and pushing steps are repeated, and the adjacent L-shaped abutment frames are used to realize the layer-by-layer transfer of the steel cast plates, so as to realize high-place loading;

[0020] This structure ensures that each group of steel casting plates are fed in order through intermittent progressive upward transmission, achieving continuous material feeding. It not only reduces complex processes such as lifting and transportation, but also facilitates the control of the feeding interval of a single group of steel casting plates, reduces collision damage between steel casting plates, and improves the efficiency of oblique upward feeding of steel castings.

[0021] 2. The present invention is assisted by the anti-slip assembly and the guide mechanism. During the transmission and feeding process of a single set of steel plates, the front and rear ends of the steel cast plate slide respectively between the two sets of oblique sliding frames, and the front and rear end plates of the steel cast plate respectively press the two sets of corresponding front and rear blocking frames, forcing the front and rear blocking frames to rotate in the opposite directions, and the clamping ring at the bottom of the push rod slides relatively along the inside of the slide groove, and the damping spring shock absorber 2 is compressed until the steel cast plate passes over the two sets of blocking frames. The two sets of blocking frames lose the pressure and the hinge force and the rebound force of the damping spring shock absorber 2 reset, and the two sets of blocking frames reset, and jointly support the side of the steel cast plate that has passed, so as to prevent the steel cast plate from sliding obliquely downward and affecting the transmission efficiency;

[0022] The structure strengthens the reverse limitation of the steel cast plate when the steel cast plate is obliquely fed upward, so as to prevent the steel cast plate from sliding in the reverse direction when the steel cast plate is obliquely fed upward, thereby further improving the transmission efficiency of the steel cast plate.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 7 As shown, the steel casting oblique conveying device with an anti-slip protection structure comprises a conveying bottom frame 1, two groups of concave lateral slide frames 2 and two groups of oblique slide frames 3, the two groups of lateral slide frames 2 are respectively slidably connected to the front and rear ends of the frame on one side of the top surface of the conveying bottom frame 1, the two groups of oblique slide frames 3 are respectively fixedly installed on the side surfaces of the two groups of lateral slide frames 2, and the lower end of the oblique slide frame 3 is embedded and slidably connected to the long groove provided on the inner wall of the bottom of the conveying bottom frame 1 and located on the opening side;

[0034] The bottom of the two groups of inclined sliding frames 3 are both embedded with anti-skid rubber pads on the inner wall, and the top surfaces of the two groups of inclined sliding frames 3 and the lower end frame bodies are fixedly installed with concave structure semi-card frames 4 with an opposite inclination angle to the inclined sliding frames 3. The two groups of semi-card frames 4 are mirror-symmetrical with respect to the central axis of the conveying bottom frame 1, and the inside of the conveying bottom frame 1 is located at the bottom surface of the two groups of inclined sliding frames 3.

[0035] The guide mechanism 5 includes a bottom plate 1 51 and a bottom plate 2 52. The bottom plate 1 51 and the bottom plate 2 52 are both at the same inclination angle as the oblique sliding frame 3. The bottom plate 1 51 and the bottom plate 2 52 are respectively fixedly installed inside the conveying bottom frame 1 and located at the head and tail ends of the bottom surface of the oblique sliding frame 3, and the bottom surface of the oblique sliding frame 3 is located at the head and tail end frame bodies and is respectively sleeved on the outside of the bottom plate 1 51 and the bottom plate 2 52. The top surfaces of the bottom plate 1 51 and the bottom plate 2 52 are slidably connected with a transmission long plate 53, and a tooth groove group is provided at the front and rear end surfaces of the transmission long plate 53 at the higher end;

[0036] The top surface of the bottom plate 1 51 is located at the front and rear ends of the transmission long plate 53 and is rotatably provided with half toothed discs 54. A rotating rod at the bottom of one group of half toothed discs 54 extends to the bottom surface of the bottom plate 1 51 and is provided with a motor 1 55. A slot 56 is provided at the lower end of the top surface of the transmission long plate 53. A round shaft 57 is fixedly installed at the center of the top surface of the bottom plate 2 52, and the round shaft 57 is slidably connected to one end inside the slot 56.

[0037] A damping spring shock absorber 58 is provided inside the slot 56 between the circular shaft 57 and the inner wall on the other side of the slot 56. A concave card seat 59 is fixedly installed at an equal distance on the top surface of the transmission long plate 53. An L-shaped support frame 510 is hingedly connected to the top notch of the concave card seat 59 and has an inclined structure. The top surface of the L-shaped support frame 510 is flush with the bottom surface of the half card frame 4.

[0038] A plurality of sets of steel casting plates are stacked together inside the front and rear sets of half-card frames 4, and the steel casting plates stacked on the bottom are located at the bottom of the half-card frames 4 and supported by the bottom inner walls of the front and rear sets of inclined sliding frames 3. The starter motor 55 drives one set of half-toothed discs 54 to rotate using the rotating shaft, and the half-toothed discs 54 are meshed with the transmission long plate 53 for transmission, forcing the transmission long plate 53 to transmit obliquely downward;

[0039] The relative movement of the slot 56 and the circular shaft 57 causes the damping spring shock absorber 58 to be compressed, and a plurality of groups of L-shaped abutment frames 510 are driven along with the transmission long plate 53. The L-shaped abutment frame 510 located at the tail end of the transmission long plate 53 first moves toward the steel casting plate superimposed on the bottom layer. The top frame body of this group of L-shaped abutment frames 510 is abutted, causing the L-shaped abutment frame 510 to deflect into a V-shaped structure until the L-shaped abutment frame 510 passes over the bottom steel casting plate and is located on the other side of the plate body. The L-shaped abutment frame loses the abutment pressure and flips back to its original position under the action of the hinge force.

[0040] At this time, the motor 1 55 continues to drive the half gear plate 54 to rotate until the teeth on the outside of the half gear plate 54 pass over the tooth groove group, the transmission long plate 53 loses the transmission force and resets under the rebound force of the damping spring shock absorber 1 58, and the transmission long plate 53 pulls the plurality of groups of L-shaped abutment frames 510 to move obliquely upward. At this time, the L-shaped abutment frames 510 located on the side of the bottom steel casting plate use the side frame edge to press and push the bottom steel casting plate to move;

[0041] The bottom steel cast plate is separated from the stacked steel cast plate group and moves obliquely upward, and the steel cast plate of a single group is moved to the adjacent L-shaped abutment frame 510, and the above-mentioned transmission and pushing steps are repeated, and the adjacent L-shaped abutment frame 510 is used to realize the layer-by-layer transmission of the steel cast plate until it is transmitted to the horizontal sliding frame 2, so as to realize high-place loading;

[0042] Through intermittent progressive upward transmission, it is ensured that each group of steel casting plates are fed in an orderly manner, and the continuity of material feeding is achieved. It not only reduces complex processes such as lifting and transportation, but also facilitates the control of the feeding interval of a single group of steel casting plates, reduces collision damage between steel casting plates, and improves the oblique upward feeding efficiency of steel castings.

[0043] Example 2: Please refer to Figure 2 , Figure 3 As shown, the bottom surface of the half-card frame 4 is 10 cm away from the bottom inner wall of the inclined sliding frame 3, and right-angled abutting blocks 301 are provided on the bottom inner walls of the two groups of inclined sliding frames 3 and on one side of the two groups of half-card frames 4. The two groups of right-angled abutting blocks 301 are used to press and block the steel cast plate superimposed on the bottom layer to prevent the steel cast plate from sliding in the opposite direction along the inner wall of the inclined sliding frame 3 and affecting the departure from the upward transmission track;

[0044] A motor 2 6 is arranged on the top frame of the conveying bottom frame 1 and between the front and rear sets of the horizontal sliding frames 2, and a double-angle turntable 7 is arranged at the top output end of the motor 2 6, and the front and rear ends of the double-angle turntable 7 are respectively hinged to the corresponding horizontal sliding frames 2 through hinge rods 8;

[0045] When the steel cast plates are piled up and before transmission, the motor 2 6 is started to drive the double-angle turntable 7 to rotate, and the two groups of hinge rods 8 are used to pull the front and rear groups of horizontal slide frames 2 closer to each other. At the same time, the two groups of oblique slide frames 3 are also closer to each other as the horizontal slide frames 2 approach, until the spacing between the front and rear groups of oblique slide frames 3 and the spacing between the front and rear groups of half-clamp frames 4 can adapt to the specification length of the steel cast plates to be transmitted, so as to assist in limiting the positioning and clamping of the plate body during the transmission process to prevent the plate body from deviating and leaving the transmission track.

[0046] Embodiment 3: Since the surface of the steel cast plate is smooth, the steel cast plate is prone to reverse slipping during the oblique progressive feeding process, which greatly affects the transfer efficiency of the steel cast plate. The anti-slip component 9 is provided to reduce the reverse slipping of the steel cast plate;

[0047] See also Figure 5 and Figure 7 As shown, the top surfaces of the two groups of conveying bottom frames 1 are provided with several groups of anti-slip components 9, which are respectively arranged on the top surfaces of the front and rear two groups of oblique sliding frames 3, and the front and rear corresponding groups of anti-slip components 9 form a pair, and the front and rear corresponding groups of anti-slip components 9 are mirror-symmetrical with respect to the central axis of the conveying bottom frame 1;

[0048] The anti-slip assembly 9 includes a blocking frame 91, which is hinged at the middle section of the inner wall of the rear end of the oblique sliding frame 3, and a slide groove 92 is provided inside the blocking frame 91, and the anti-slip assembly 9 also includes a push rod 93, which is hinged at the top surface of the oblique sliding frame 3 and is located adjacent to the blocking frame 91, and a snap ring 94 is fixedly installed on the bottom surface of the push rod 93 and at one end away from the oblique sliding frame 3, and the snap ring 94 is slidably connected to the bottom position inside the slide groove 92, and a damping spring shock absorber 2 95 is commonly provided between the snap ring 94 and the inner wall on the other side of the slide groove 92;

[0049] During the feeding process of a single set of steel plates, the front and rear ends of the steel plates slide along the two sets of oblique sliding frames 3 respectively, and the front and rear end plates of the steel plates respectively press the two sets of corresponding blocking frames 91, forcing the front and rear blocking frames 91 to rotate in the opposite directions, and the clamping ring 94 at the bottom of the push rod 93 slides relatively along the inside of the slide groove 92, and the damping spring shock absorber 2 95 is compressed until the steel plates pass over the two sets of blocking frames 91. The two sets of blocking frames 91 lose the pressure and the hinge force and the rebound force of the damping spring shock absorber 2 95 reset. At this time, the two sets of blocking frames 91 reset and jointly support the side of the steel plates that have passed, so as to prevent the steel plates from sliding obliquely downward and affecting the transmission efficiency.

[0050] The structure strengthens the reverse limitation of the steel cast plate when the steel cast plate is obliquely fed upward, so as to prevent the steel cast plate from sliding in the reverse direction when the steel cast plate is obliquely fed upward, thereby further improving the transmission efficiency of the steel cast plate.

[0051] When the present invention is used, a plurality of groups of steel cast plates are stacked together inside the front and rear groups of half-card frames 4, and the steel cast plates stacked on the bottom are located at the bottom of the half-card frames 4 and supported by the bottom inner walls of the front and rear groups of inclined sliding frames 3, and then the motor 55 is started to drive one group of half-toothed discs 54 to rotate, and the half-toothed discs 54 are meshed with the transmission long plate 53 for transmission, forcing the transmission long plate 53 to transmit obliquely downward;

[0052] The relative movement of the slot 56 and the circular shaft 57 causes the damping spring shock absorber 58 to be compressed, and a plurality of groups of L-shaped abutment frames 510 are driven along with the transmission long plate 53. The L-shaped abutment frame 510 located at the tail end of the transmission long plate 53 first moves toward the steel casting plate superimposed on the bottom layer. The top frame body of this group of L-shaped abutment frames 510 is abutted, causing the L-shaped abutment frame 510 to deflect into a V-shaped structure until the L-shaped abutment frame 510 passes over the bottom steel casting plate and is located on the other side of the plate body. The L-shaped abutment frame loses the abutment pressure and flips back to its original position under the action of the hinge force.

[0053] At this time, the motor 1 55 continuously drives the half toothed disc 54 to rotate until the teeth on the outside of the half toothed disc 54 pass over the tooth groove group, the transmission long plate 53 loses the transmission force and resets under the rebound force of the damping spring shock absorber 1 58, and the transmission long plate 53 pulls a plurality of groups of L-shaped abutment frames 510 to move obliquely upward. At this time, the L-shaped abutment frames 510 located on the side of the bottom steel cast plate use the side frame edge to push the bottom steel cast plate to move, and the bottom steel cast plate is separated from the stacked steel cast plate group and moves obliquely upward. The single group of transferred steel cast plates moves to the adjacent L-shaped abutment frames 510, and the above-mentioned transmission and pushing steps are repeated, and the adjacent L-shaped abutment frames 510 are used to realize the layer-by-layer transfer of the steel cast plates;

[0054] During this process, the front and rear ends of the steel cast plate slide between the two groups of inclined sliding frames 3 respectively, and the front and rear end plates of the steel cast plate respectively press against the two corresponding groups of blocking frames 91, forcing the front and rear blocking frames 91 to rotate in opposite directions, and the retaining ring 94 at the bottom of the support rod 93 slides relatively along the inside of the slide groove 92, and the damping spring shock absorber 2 95 is compressed until the steel cast plate passes over the two groups of blocking frames 91. The two groups of blocking frames 91 lose the pressure and are reset by the hinge force and the rebound force of the damping spring shock absorber 2 95. At this time, the two groups of blocking frames 91 are reset and jointly support the side of the steel cast plate that has passed until it is transmitted to the horizontal sliding frame 2 for high-altitude loading.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
