Technical Field

[0001] The utility model relates to the technical field of anti-retreat devices, in particular to an anti-retreat device. Background Art

[0002] The accumulation conveyor is a three-dimensional space closed-loop continuous conveying system, which is suitable for the automatic conveying of finished goods inside and between workshops. In modern industrial production, it has been widely used in industries such as machinery, automobiles, steel rolling, aluminum smelting, light industry, household appliances, chemical industry, and building materials. In the accumulation conveyor, the goods are conveyed by the carrying trolley moving on the guide rail. During the conveying process, the carrying trolley needs to stop at a designated position, and after stopping, it is necessary to prevent the carrying trolley from reversing backward to ensure the safe and stable operation of the conveying system. Based on this, the inventor proposed an anti-retreat device to realize the anti-retreat blocking of the carrying trolley and ensure the safe and stable operation of the conveying system.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The purpose of the present utility model is to provide an anti-retreat device to solve the problems existing in the prior art, and it can realize the anti-retreat block of the carrier trolley to ensure the safe and stable operation of the conveying system.

[0025] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] As Figures 1-6 shown, the present utility model provides an anti-retreat device, including a mounting frame 1, a fixing plate 2, an anti-retreat plate 3 and a limit block 4. The mounting frame 1 is used for fixedly installing on the guide rail 5. The fixing plate 2 is installed on the mounting frame 1. The anti-retreat plate 3 is rotatably connected to the fixing plate 2 through a rotating shaft 6. One end of the anti-retreat plate 3 below the rotating shaft 6 is the anti-retreat end 7, and the anti-retreat end 7 is provided with anti-retreat teeth 8 for cooperating with the limit plate 10 on the carrier trolley 9 to perform anti-retreat. One end of the anti-retreat plate 3 above the rotating shaft 6 is the limit end 11. The limit block 4 is arranged on the upper side of the limit end 11 and fixed to the fixing plate 2. The limit block 4 is used for blocking the limit end 11 to prevent the limit end 11 from swinging upward. Under the action of the self-weight of the anti-retreat plate 3, the anti-retreat end 7 has a tendency to swing downward.

[0027] During use, when the anti-reverse plate 3 is not in contact with the limit plate 10 of the carrying trolley 9, under the limiting action of the limit block 4, it can prevent the limiting end 11 of the anti-reverse plate 3 from swinging upward, making the anti-reverse plate 3 stable and immobile. When the carrying trolley 9 moves along the traveling direction until it contacts the anti-reverse plate 3, the carrying trolley 9 continues to move and pushes the anti-reverse end 7 of the anti-reverse plate 3 to swing upward. When the carrying trolley 9 reaches the limit end point, the anti-reverse end 7 descends, and the limit plate 10 of the carrying trolley 9 is clamped with the anti-reverse teeth 8 to form a limit on the carrying trolley 9, realizing the anti-reverse block of the carrying trolley 9 and ensuring the safe and stable operation of the conveying system.

[0028] In this embodiment, the mounting frame 1 includes a slide rail 101, a connecting plate 102, a slider 103 and a fastening bolt 104. Both ends of the slide rail 101 are respectively fixedly connected with a connecting plate 102, and the two connecting plates 102 are used to be fixed on the guide rail 5. The slider 103 is slidably arranged in the slideway 105 inside the slide rail 101. An opening long groove 106 communicating with the slideway 105 is arranged on one side of the slide rail 101 along its length direction. At least two through holes 201 are arranged on the fixing plate 2, and each through hole 201 is respectively penetrated by a fastening bolt 104. Each fastening bolt 104 passes through the through hole 201 and the opening long groove 106 and is respectively threadedly connected with a slider 103. By sliding the slider 103 in the slideway 105, the position of the fixing plate 2 can be adjusted, thereby adjusting the anti-reverse position of the anti-reverse plate 3, and the adjustment is convenient and fast.

[0029] In this embodiment, one end of the rotating shaft 6 is threadedly connected to the fixing plate 2, which is convenient for disassembly and assembly.

[0030] In this embodiment, a bearing is arranged between the rotating shaft 6 and the anti-reverse plate 3 to reduce the friction of the anti-reverse plate 3 during rotation and reduce wear.

[0031] In this embodiment, the anti-reverse teeth 8 are serrated anti-reverse teeth. By clamping the limit plate 10 of the carrying trolley 9 with different tooth grooves, the anti-reverse of the carrying trolley 9 at multiple different positions at the anti-reverse teeth 8 can be realized.

[0032] In this embodiment, when the limiting end 11 abuts against the limit block 4, the horizontal distance h between two adjacent tooth tips in the anti-reverse teeth 8 is 15 mm.

[0033] In this embodiment, the slide rail 101 is a square slide rail, the slideway 105 is a square slideway, and the slider 103 is a square slider.

[0034] In this embodiment, an inclined slope 12 is provided on the upstream side of the backstop plate 3. The inclined slope 12 is inclined downward from its upstream end to its downstream end. The backstop teeth 8 are located on the downstream side of the inclined slope 12. The upstream and downstream mentioned above are in terms of the traveling direction of the carrying trolley 9. When the carrying trolley 9 travels, it first contacts the inclined slope 12, and then pushes the backstop end 7 of the backstop plate 3 to swing upward until it reaches the position of the backstop teeth 8. The limit plate 10 of the carrying trolley 9 is clamped with the tooth grooves of the backstop teeth 8 to achieve the backstop block of the carrying trolley 9. The setting of the inclined slope 12 enables the limit plate 10 of the carrying trolley 9 to smoothly pass through the backstop plate 3, so as to facilitate the backstop function when the next carrying trolley 9 arrives.

[0035] In the present utility model, specific examples are used to illustrate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
