Description

Technical Field

[0001] The present invention relates to the technical field of cable trench cover production, and more specifically, to a continuous loading and unloading device based on the manufacture of magnetic cable trench cover. Background Art

[0002] With the progress and development of modern society, people's living standards are constantly improving, thanks to the construction and development of continuously improved infrastructure. Among them, the importance of tunnel construction is unquestionable. The installation of cable trench covers is an important process in tunnel construction. Excavation and masonry are carried out according to design requirements. The side walls of the trench are welded with load-bearing angle steel frames and grounded as required. The underground trench covered with a cover is the cable trench. It is a special underground channel for laying cables. Loading and unloading devices are required during the production of cable trench covers.

[0003] For example, utility model patent CN222081775U discloses a loading and unloading device for cable trench cover production, which realizes the automatic loading function by means of a slide groove, a slider, a push block, a spring, a fixing plate, a threaded rod and a forward and reverse motor. The forward and reverse motor is started to drive the threaded rod to rotate, thereby driving the slider to slide inside the slide groove, and then driving the push block to push the bottom cover, thereby realizing the function of continuous automatic loading, without the need for workers to continuously discharge materials onto the surface of the conveyor belt; However, the above-mentioned patent document only has the function of placing the trench cover plate. In actual use, since the trench cover plate needs to undergo processing operations such as welding, the prior art lacks a structure that can transport the trench cover plate individually to the processing table and send it out individually after the processing is completed. Therefore, the two operations of loading and unloading the trench cover plate cannot be continuous, resulting in manual loading and unloading of the trench cover plate during manufacturing. At the same time, there is also a lack of a structure to stabilize the trench cover plate during the transportation process.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0025] Embodiment 1: In view of the lack of a structure in the prior art that can transport the trench cover plate to the processing table separately and send it out separately after the processing is completed, it is impossible to achieve the effect of continuous loading and unloading of the trench cover plate, resulting in the need for manual loading and unloading during the manufacturing of the trench cover plate. In order to solve this problem, the following technical solution is proposed: Refer to the instruction manual Figure 1-Figure 7 , based on the continuous loading and unloading device manufactured by magnetic cable trench cover, such as Figure 1 and Figure 2 As shown, it comprises a conveying platform 1, a conveying belt 2 is arranged on the top of the conveying platform 1, a positioning frame 3 is fixedly installed on the top of the conveying platform 1, a processing platform 4 is arranged on the top of the positioning frame 3, and a material lifting mechanism 5 and a material pushing mechanism 6 are arranged on the top of the conveying platform 1; like Figure 3 and Figure 4 As shown, the material lifting mechanism 5 includes a transfer platform 51 arranged on one side of the conveyor belt 2, the transfer platform 51 is fixedly mounted on the top of the conveyor platform 1, an electric telescopic cylinder 52 is arranged at the bottom of the transfer platform 51, the electric telescopic cylinder 52 is fixedly mounted inside the conveyor platform 1, a lifting and pushing plate 53 is fixedly mounted on the top of the electric telescopic cylinder 52, the lifting and pushing plate 53 is located at the top of the transfer platform 51, a limiting plate 54 is sleeved on one side of the lifting and pushing plate 53, the limiting plate 54 is fixedly mounted on the top of the transfer platform 51, and the limiting plate 54 is arranged in a vertical state; When the conveyor belt 2 delivers the trench cover to the top of the lift plate 53 on the transfer table 51, the limit plate 54 is used to block the trench cover so that the trench cover stops moving forward and is on the lift plate 53. At this time, the electric telescopic cylinder 52 is started to drive the lift plate 53 to lift the trench cover upward under the state of being limited by the limit plate 54 and send it to the processing table 4 for processing.

[0026] like Figure 3 and Figure 4 As shown, a fixed limiting plate 55 is fixedly installed on one side of the lifting and pushing plate 53. The fixed limiting plate 55 is arranged in a vertical state, and the top of the fixed limiting plate 55 is arranged tilted downward. The fixed limiting plate 55 and the top of the conveyor belt 2 are arranged perpendicular to each other. The lifting and pushing plate 53 moves upward and drives the fixed limiting plate 55 to move upward synchronously. At this time, the fixed limiting plate 55 blocks and pushes out the next trench cover through its inclined surface and vertical surface, so as to prevent the next trench cover from being lifted synchronously.

[0027] like Figure 4 and Figure 5 As shown, the pushing mechanism 6 includes a tilting plate 61 rotatably mounted on the top of the lifting and pushing plate 53. The tilting plate 61 is arranged in a horizontal state. The length of the tilting plate 61 is greater than the length of the lifting and pushing plate 53. The tilting plate 61 is located in the middle of the lifting and pushing plate 53. The lifting and pushing plate 53 moves upward, driving the tilting plate 61 located at the bottom of the trench cover plate to move upward synchronously.

[0028] like Figure 4 and Figure 5 As shown, a supporting plate 62 is provided on the top of the tilting plate 61, and the supporting plate 62 and the tilting plate 61 are arranged parallel to each other, and the horizontal height of the top of the supporting plate 62 is higher than the horizontal height of the top of the limiting plate 54, and a positioning frame 63 is rotatably installed on one side of the supporting plate 62, and the positioning frame 63 is fixedly installed on the top of the conveying platform 1, and a limited resistance block 64 is fixedly installed on one side of the positioning frame 63, and the limited resistance block 64 and the bottom of the tilting plate 61 are fitted with each other, and a limiting spring 65 is fixedly installed on the top of the tilting plate 61, and the limiting spring 65 is fixedly installed on the outer wall of the positioning frame 63, and then the tilting plate 61 moves up and approaches the supporting plate 62 and lifts the supporting plate 62 to rotate and compress the limiting spring 65, and when the lifting and pushing plate 53 drives the processed trench cover plate to move downward, the tilting plate 61 is lifted up due to the squeezing of the supporting plate 62 limited by the limiting resistance block 64, and then the tilting plate 61 is tilted by force to push the trench cover plate out.

[0029] like Figure 4 and Figure 5As shown, a slide plate 66 is provided on one side of the limit plate 54, and the slide plate 66 is fixedly installed on the top of the conveyor platform 1. The slide plate 66 is arranged downward in an arc shape, and a feeding belt 67 is provided at the bottom of the slide plate 66. A motor for rotating the feeding belt 67 is arranged on one side of the feeding belt 67. The feeding belt 67 is arranged on the top of the conveyor platform 1. The groove cover plate sliding out from the top of the inclined tilting plate 61 on the lifting and pushing plate 53 passes over the top of the limit plate 54 and falls onto the slide plate 66, and is sent to the feeding belt 67 by the slide plate 66, and the groove cover plate is brought out by the feeding belt 67 to complete the unloading work.

[0030] In specific implementation, when the conveyor belt 2 delivers the trench cover to the top of the lifting and pushing plate 53 on the transfer table 51, the trench cover is stopped by the limit plate 54 so that the trench cover stops moving forward and is on the lifting and pushing plate 53. At this time, the electric telescopic cylinder 52 is started to drive the lifting and pushing plate 53 to lift the trench cover upward under the limit of the limit plate 54 and send it to the processing table 4 for processing. The lifting and pushing plate 53 moves upward to drive the fixed limit plate 55 to move upward synchronously. At this time, the fixed limit plate 55 blocks and pushes out the next trench cover through its inclined surface and vertical surface to prevent the next trench cover from being lifted synchronously. The upward movement of the lifting and pushing plate 53 drives the tilting plate 61 located at the bottom of the trench cover plate to move upward synchronously. When the tilting plate 61 moves upward, it approaches the supporting plate 62 and lifts up the supporting plate 62 to rotate and compress the limit spring 65. When the lifting and pushing plate 53 drives the processed trench cover plate to move downward, the tilting plate 61 is lifted up due to the squeezing of the supporting plate 62 restricted by the limit block 64, and then the tilting plate 61 is tilted by force to push the trench cover plate out. The trench cover plate that slides out from the top of the tilted tilting plate 61 on the lifting and pushing plate 53 passes over the top of the limit plate 54 and falls onto the slide plate 66, and is sent to the feeding belt 67 by the slide plate 66, and the trench cover plate is brought out by the feeding belt 67 to complete the unloading work.

[0031] Embodiment 2: In view of the fact that the prior art lacks a structure for stabilizing the trench cover during its transportation, that is, the trench cover is difficult to maintain a flat and identical state during production and transportation, which greatly affects the continuity and stability of the trench cover during production. To solve this problem, the following technical solution is proposed: like Figure 6 and Figure 7 As shown, a pushing and clamping mechanism 7 is provided on the top of the conveyor belt 2. The pushing and clamping mechanism 7 includes rotating rods 71 ​​fixedly installed on both sides of the conveyor belt 2. The two rotating rods 71 ​​are rotatably installed on the inner wall of the conveying platform 1. The outer walls of the two rotating rods 71 ​​are fixedly installed with first bevel gears 72. The tops of the two first bevel gears 72 are respectively meshed with second bevel gears 73. The two second bevel gears 73 are rotatably installed on the top of the conveying platform 1. When the conveyor belt 2 rotates, the rotating rods 71 ​​on both sides are driven to make the first bevel gears 72 on both sides rotate synchronously, that is, the first bevel gears 72 drive the second bevel gears 73 on both sides to rotate synchronously.

[0032] like Figure 6 and Figure 7As shown, a first pulley 74 is fixedly installed on the top of the two second bevel gears 73, and a synchronous belt 75 is rotatably installed on the outer wall of the two first pulleys 74. A second pulley 76 is rotatably installed on one side of the two synchronous belts 75, and a roller clamping wheel 77 is fixedly installed on the bottom of the two second pulleys 76. The two roller clamping wheels 77 are symmetrically arranged. The two roller clamping wheels 77 are respectively located on both sides of the lifting and pushing plate 53. The second bevel gears 73 on both sides drive the first pulley 74 through the synchronous belt 75 to make the second pulleys 76 on both sides rotate synchronously, that is, the second pulleys 76 on both sides drive the roller clamping wheels 77 on both sides to rotate synchronously, so that the roller clamping wheels 77 on both sides rotate to contact the two sides of the groove cover plate that is close to the fitting, and the two sides of the groove cover plate are pushed by rotation to make it parallel to the limit plate 54, so as to facilitate the alignment of the limit plate 54 with the limit plate 54.

[0033] like Figure 6 and Figure 7 As shown, a sliding push rod 78 is rotatably installed on the top of the two second pulleys 76, and the two sliding push rods 78 are slidably installed on the inner wall of the positioning frame 3. The two sliding push rods 78 are arranged in an arc shape, and the two sliding push rods 78 and the synchronous belt 75 are arranged corresponding to each other. The outer walls of the two sliding push rods 78 are hinged with a tension spring 79, and the two tension springs 79 are rotatably installed on the outer wall of the positioning frame 3. The sliding push rods 78 on both sides are squeezed by the tension springs 79, and the two second pulleys 76 are driven to clamp and squeeze in the middle by the sliding push rods 78 on both sides, so that the second pulleys 76 on both sides drive the roller clamping wheel 77 to clamp the two sides of the limit plate 54, so as to stabilize the limit plate 54.

[0034] In specific implementation, when the conveyor belt 2 rotates, it drives the rotating rods 71 ​​on both sides to make the first bevel gears 72 on both sides rotate synchronously, that is, the first bevel gears 72 drive the second bevel gears 73 on both sides to rotate synchronously, and the second bevel gears 73 on both sides drive the first pulley 74 through the synchronous belt 75 to make the second pulleys 76 on both sides rotate synchronously, that is, the second pulleys 76 on both sides drive the roller clamping wheels 77 on both sides to rotate synchronously, so that the roller clamping wheels 77 on both sides rotate to contact the two sides of the trench cover plate close to the fitting, and the two sides of the trench cover plate are pushed by rotation to make it parallel to the limit plate 54, so that the limit plate 54 is aligned with the limit plate 54; At the same time, the push rods 78 on both sides are squeezed by the tension springs 79, and the push rods 78 on both sides push the two second pulleys 76 to clamp and squeeze them in the middle, so that the second pulleys 76 on both sides drive the roller clamping wheels 77 to clamp the two sides of the limit plate 54, so as to stabilize the limit plate 54.
