Description

Technical Field

[0001] This utility model relates to the field of steel arch frame production technology, and in particular to a conveying device suitable for steel arch frame production lines. Background Technology

[0002] Steel arch frames utilize L-shaped, U-shaped, and I-shaped steel, as well as steel rails and pipes, processed into the required shapes. They are used as integral installations or as component assemblies to reinforce underground engineering support measures. They can be combined with anchor bolts, shotcrete, and steel mesh to form composite support systems.

[0003] The patent specification with announcement number CN202320681415.4 discloses a splicing assembly line conveyor device, "including a first vertical plate; a second vertical plate is installed on one side of the first vertical plate, and a conveyor belt is connected between the first vertical plate and the second vertical plate. The upper end surfaces of the first vertical plate and the second vertical plate are higher than the upper end surface of the conveyor belt. Grooves are opened on the upper end surfaces of adjacent sides of the first vertical plate and the second vertical plate. Multiple rolling devices are equidistantly arrayed and rotatably connected in the grooves. Through the provided first vertical plate, second vertical plate, conveyor belt, grooves, bearings, rolling devices, cylinders and circular grooves, the conveyor belt installed between the first vertical plate and the second vertical plate extends through the grooves opened in a section of the upper end surface of the conveyor belt. The rolling devices rotatably connected on the bearings in the grooves can reduce the friction of the items and facilitate the transportation of the items."

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned conveying device: the traditional conveying device has poor protection effect during the conveying process, and mostly uses a single protective plate for shielding. However, due to the variety of steel arch frame specifications, the diameter and curvature of the conveyed steel arch frames are different. When they are transported by conveyor belt, they are very easy to tip over and cause the conveyed steel arch frames to stack together. After the conveying is completed, they need to be moved and sorted manually, which reduces the conveying efficiency of the production line. In view of this, a conveying device suitable for steel arch frame production line is provided to overcome the above defects. Utility Model Content

[0023] Reference Figure 1-5 This utility model provides a conveying device suitable for a steel arch frame production line: it includes a bin body 1, inside which two conveying rollers 2 are rotatably connected by bearings, and a conveyor belt 3 is driven between the two conveying rollers 2. Tensioning wheels 4 are slidably connected to both sides of the bin body 1. Tensioning components 5 are provided at the bottom of the bin body 1. Guide plates 6 are fixedly provided on both sides of the top of the bin body 1. Two cams 7 are provided at the top of each of the two guide plates 6. A rotating shaft 8 is rotatably connected between each pair of opposite cams 7 by bearings. Protective components 9 are provided on the surface of each of the two rotating shafts 8. A first motor 21 is fixedly provided on one side of the front of the bin body 1. The drive shaft of the first motor 21 is fixedly connected to one of the conveying rollers 2. A second motor 22 is fixedly provided on one side of each of the two cams 7. The drive shafts of the two second motors 22 are respectively fixedly connected to the two rotating shafts 8.

[0024] As a further implementation of the above technical solution: the tensioning assembly 5 includes an electric push rod 51, a bracket 52, and two auxiliary shafts 53. The electric push rod 51 is fixedly installed in the middle of the bottom of the inner chamber 1. The push rod of the electric push rod 51 is fixedly connected to the bracket 52. The middle of both sides of the bracket 52 is rotatably connected to the auxiliary shafts 53 through bearings. One end of the two auxiliary shafts 53 is fixedly connected to two tensioning wheels 4 respectively. The push rod of the electric push rod 51 drives the bracket 52 to move down, and at the same time, the two tensioning wheels 4 follow the two auxiliary shafts 53 to move down, thereby tensioning the bottom of the conveyor belt 3, which can effectively prevent the conveyor belt 3 from becoming loose during the conveying process.

[0025] As a further implementation of the above technical solution: each of the two protective components 9 includes a protective frame 91, two screws 92, a top plate 93, several bases 94, several locking holes 95, several locking rods 96, and several mounting seats 97. The two protective frames 91 are respectively fixedly installed on the surfaces of the two rotating shafts 8. The top ends of both sides of the two protective frames 91 are threaded with screws 92. The top ends of the two protective frames 91 are respectively fixedly connected to the top plate 93 through two screws 92. Several bases 94 are fixedly installed at the bottom inside the protective frame 91. The inner walls of the several bases 94 are provided with locking holes 95. The inner walls of the several locking holes 95 are engaged with locking rods 96. Several mounting seats 97 are fixedly installed at the bottom ends of the two top plates 93.

[0026] Each of the mounting bases 97 has a sliding hole 10 on its inner wall. Each of the sliding holes 10 has a sliding plate 11 slidably connected to its inner wall. Each of the two sliding plates 11 has a protrusion 12 fixed on one side. Each of the two top sides of the locking rods 96 has a concave hole 13 that matches the protrusion 12. Each of the sliding holes 10 has a return spring 14 fixed on one side of its inner wall. One end of each return spring 14 is fixedly connected to each of the sliding plates 11. Each of the sliding plates 11 has a pull rod 15 fixed on the other side.

[0027] Each of the several clamping rods 96 has a protective plate 23 fixedly mounted on its surface. Each of the protective plates 23 has an arc-shaped groove on one side. During the conveying process, the device is started by two second motors 22 to drive two rotating shafts 8 to rotate, thereby tilting the two protective frames 91 and the several protective plates 23 at an appropriate angle, so that the arc-shaped grooves on the surface of the several protective plates 23 are matched with the arc of the steel arch frame to be conveyed, thus providing protection according to the specifications of the steel arch frame. By rotating several screws 92, the two protective frames 91 can be separated from the two top plates 93 respectively. Then, by pulling several pull rods 15 in sequence, several sliding plates 11 can slide along the inner wall of several sliding holes 10 respectively. After the several return springs 14 are contracted, several protrusions 12 are separated from several concave holes 13, thereby allowing several clamping rods 96 to be pulled out from several mounting seats 97, thus facilitating the disassembly and maintenance of several protective plates 23.

[0028] As a further implementation of the above technical solution: the inner walls of the two guide plates 6 are provided with grooves 16, the inner walls of the two grooves 16 are slidably connected with slide plates 17, the inner walls of the two slide plates 17 are rotatably connected with a number of guide shafts 18 through bearings, the surfaces of the number of guide shafts 18 are fixedly provided with guide wheels 19, and a number of shock absorbers 20 are fixedly provided on one side of the inner wall of the two grooves 16. One end of the number of shock absorbers 20 is fixedly connected to the two slide plates 17 respectively. The elasticity of the number of shock absorbers 20 causes the two slide plates 17 to slide out of the two grooves 16 respectively. After the number of guide wheels 19 rub against the steel arch frame, they rotate on the surfaces of the number of guide shafts 18 respectively, thereby facilitating the stable conveying of steel arch frames of different diameters and lengths.

[0029] As a further implementation of the above technical solution: a switch panel 24 is fixedly provided on one side of the compartment 1. The surface of the switch panel 24 is provided with a first motor switch, a second motor switch and an electric push rod switch. The first motor 21, the two second motors 22 and the electric push rod 51 are electrically connected to the power supply through the first motor switch, the second motor switch and the electric push rod switch respectively.

[0030] Working Principle: When using this invention, firstly, two second motors 22 are started to drive two rotating shafts 8 to rotate, thereby tilting two protective frames 91 and several protective plates 23 at appropriate angles. This allows the arc-shaped grooves on the surfaces of the protective plates 23 to match the curvature of the steel arch frame to be conveyed. Next, the steel arch frame is placed at one end of the conveyor belt 3. At this time, the first motor 21 is started to drive the conveyor belt 3 between two conveyor rollers 2, thus conveying the steel arch frame placed on the surface of the device. During the conveying process, the elasticity of several shock absorbers 20 causes two sliding plates 17 to slide out of two sliding grooves 16 respectively. Several guide wheels 19 rub against the steel arch frame and rotate on the surfaces of several guide shafts 18, thereby facilitating the stable conveying of steel arch frames of different diameters and lengths. When the conveyor belt 3 becomes loose after long-term use, the push rod of the electric push rod 51 drives the bracket 52 to move down. At the same time, the two tensioning wheels 4 follow the two auxiliary shafts 53 to move down, thereby tensioning the bottom of the conveyor belt 3. This effectively prevents the conveyor belt 3 from becoming loose during the conveying process. By rotating several screws 92, the two protective frames 91 can be separated from the two top plates 93. Then, by pulling several pull rods 15 in sequence, several sliding discs 11 can slide along the inner wall of several sliding holes 10. After the several return springs 14 contract, several protrusions 12 can be separated from several concave holes 13. This allows several locking rods 96 to be pulled out from several mounting seats 97, which facilitates the disassembly and maintenance of several guard plates 23.
