Technical Field

[0001] The utility model relates to the technical field of cargo handling equipment, in particular to an automatic swing device for a conveyor belt of a loading and unloading vehicle machine. Background Art

[0002] In the field of warehousing logistics, the loading and unloading of goods stacks by forklifts driven by workers is common. With the increase in labor costs and the growing demand for logistics automation, it is becoming more and more urgent to automate the loading and unloading of goods stacks. During the process of loading and unloading goods with existing equipment ( Figure 1 as shown), a hinge rotational connection is formed between the transmission line and the fixed point of the swing arm. When the lifting power (electric cylinder or oil cylinder) extends or retracts, the assembly line forms an upward or downward swing angle movement.

[0003] The deficiencies of the above operations are as follows:

[0004] 1. A large driving force is required when the power is started, and the strength requirement for the structure is high.

[0005] 2. A large power of the motor is required to complete the drive.

[0006] 3. The frame is an integral frame, and there will also be an angle at the end transmission during the swing angle.

[0007] Based on this, an automatic swing device for a conveyor belt of a loading and unloading vehicle machine is now provided, which can eliminate the drawbacks of existing devices. Summary of the Utility Model

[0008] The purpose of the utility model is to provide an automatic swing device for a conveyor belt of a loading and unloading vehicle machine, which solves the problem of insufficient transmission in the prior art.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

A quadrilateral frame body is arranged between the two installation crossbeams. A conveyor belt group for transporting goods is arranged on the quadrilateral frame body. The conveyor belt group includes at least one first transmission line and a second transmission line. A lifting bracket is arranged at one end of the installation crossbeam. A lifting assembly for generating upward power at one end of the quadrilateral frame body is arranged on the lifting bracket. The other end of the quadrilateral frame body is rotatably connected to a hinge seat, and the hinge seat is fixedly arranged on the installation crossbeam.

[0011] On the basis of the above technical solutions, the utility model also provides the following optional technical solutions:

[0012] In an optional solution: the first transmission line and the second transmission line respectively include two conveyor belts and transmission rollers matching the conveyor belts, and the transmission rollers are connected to transmission motors for driving them to rotate.

[0013] In an alternative embodiment: The lifting assembly includes a lifting chute provided on the side of the lifting bracket. A lifting screw is vertically provided in the lifting chute. A lifting slider is slidably provided in the lifting chute. The lifting slider is in threaded engagement with the lifting screw. A lifting wheel is rotatably provided at the lower end of the lifting slider. A transmission member matching the lifting wheel is provided outside the quadrilateral frame body. The upper end of the lifting screw is connected to a drive belt group for driving its rotation.

[0014] In an alternative embodiment: A wear-resistant layer is provided outside the lifting wheel.

[0015] In an alternative embodiment: The drive belt group is a belt assembly. The belt assembly includes a driven pulley provided at the upper end of the lifting chute. The driven pulley is in transmission connection with the drive pulley.

[0016] In an alternative embodiment: The transmission member includes a lifting side plate provided outside the quadrilateral frame body. The lifting side plate is a rectangular block. A lifting groove is formed on the surface of the rectangular block. The lifting groove is arranged along the length direction of the quadrilateral frame body.

[0017] In an alternative embodiment: An anti-off ring matching the lifting wheel is provided outside the lifting groove.

[0018] In an alternative embodiment: The quadrilateral frame body includes an upper shelf plate and a lower shelf plate. The upper shelf plate is parallel to the upper side of the lower shelf plate. The rotating ends of the upper shelf plate and the lower shelf plate are rotatably connected to the hinge seat through a rotating shaft. The lifting ends of the upper shelf plate and the lower shelf plate are rotatably connected to the head of the swing arm through a rotating shaft. The upper shelf plate, the lower shelf plate, the head of the swing arm, and the hinge seat form a parallelogram.

[0019] In an alternative embodiment: The transmission speed of the first transmission line is lower than that of the second transmission line, which helps to separate the goods from each other.

[0020] In an alternative embodiment: The drive source of the drive belt group is a synchronous motor.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. By arranging the driving power close to the end of the swing arm, the present utility model has a lower requirement for the power of the driving force, reduces the driving cost, makes the equipment easier to promote, and also reduces the requirement for the structural strength and the processing difficulty.

[0023] 2. In the present utility model, the conveyor belt can be powered and divided into two sections for transmission and material separation. The transmission speed of the first transmission line is lower than that of the second transmission line, which helps to separate the goods from each other and improve the transmission efficiency.

[0024] 3. The lifting frame body in the present utility model is a quadrilateral frame body, and the quadrilateral frame body is a parallelogram mechanism. When lifting goods, the swing arm can ensure the front end is horizontal during the swinging process, avoiding tilting and ensuring the stability of handling.

[0025] Specifically: The head of the swing arm, the upper mounting plate, the lower mounting plate, and the hinge seat are the four sides of a parallelogram. Since the hinge seat is always in a vertical state, and both the upper mounting plate and the lower mounting plate have independent acting points on the side. When the lifting force acts on the lifting groove, one end of the upper mounting plate and the lower mounting plate rotates around the hinge seat, and the head of the swing arm connected to the other end of the upper mounting plate and the lower mounting plate will remain parallel to the hinge seat. In this way, when lifting, the problem of tilting of the head of the swing arm is avoided, ensuring the stability of the goods. Brief Description of the Drawings

[0034] 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 of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] AsFigures 2 - 5 As shown in the figure, the embodiment of the utility model provides an automatic swing device for a conveyor belt of a loading and unloading vehicle, which includes two mounting crossbeams 205. A quadrilateral frame body 100 is arranged between the two mounting crossbeams 205. A conveyor belt group for transmitting goods is arranged on the quadrilateral frame body 100. The conveyor belt group includes at least one first transmission line 101 and a second transmission line 102. One end of the mounting crossbeam 205 is provided with a lifting bracket 200. A lifting component for generating an upward power at one end of the quadrilateral frame body 100 is arranged on the lifting bracket 200. The other end of the quadrilateral frame body 100 is rotatably connected to a hinge seat 206. The hinge seat 206 is fixedly arranged on the mounting crossbeam 205. By generating power for one end of the quadrilateral frame body 100 through the lifting component, the quadrilateral frame body 100 rotates along the mounting crossbeam 205 to complete the swinging operation;

[0036] The first transmission line 101 and the second transmission line 102 each include two conveyor belts and transmission rollers matching the conveyor belts. The transmission rollers are connected to transmission motors for driving their rotation;

[0037] The lifting component includes a lifting chute 202 arranged on the side of the lifting bracket 200. A lifting screw 201 is vertically arranged in the lifting chute 202. A lifting slide 203 is slidably arranged in the lifting chute 202. The lifting slide 203 is in threaded cooperation with the lifting screw 201. A lifting wheel 204 is rotatably arranged at the lower end of the lifting slide 203. A wear-resistant layer is arranged on the outer side of the lifting wheel 204. A transmission part matching the lifting wheel 204 is arranged on the outer side of the quadrilateral frame body 100. The upper end of the lifting screw 201 is connected to a driving belt group 207 for driving its rotation. By driving the driving belt group 207 to drive the relative rotation of the lifting slide 203 and the lifting screw 201, under the action of the thread, the lifting slide 203 will move up and down in the lifting chute 202 to obtain the lifting power;

[0038] Here, the power is driven in a way that the power is close to the end of the swing arm, and the power requirement for the driving force is lower. The conveyor belt is divided into two sections of power for transmission and feeding;

[0039] The driving belt group 207 here is a belt assembly. The belt assembly includes a driven belt pulley arranged at the upper end of the lifting chute 202. The driven belt pulley is in transmission connection with the driving belt pulley. The driving belt pulley is connected to a driving motor for driving its rotation. This transmission method is a conventional drive, so it will not be elaborated here;

[0040] The transmission member includes a lifting side plate 104 arranged on the outside of the quadrilateral frame body 100. The lifting side plate 104 is a rectangular block. A lifting groove 103 is provided on the surface of the rectangular block. The lifting groove 103 is arranged along the length direction of the quadrilateral frame body 100. An anti-slip ring matching the lifting wheel 204 is provided on the outside of the lifting groove 103. During actual installation, the lifting wheel 204 is inserted into the lifting groove 103. When the lifting slide 203 drives the lifting wheel 204 to move upward, the lifting wheel 204 will slide along the inside of the lifting groove 103, and the problem of surface interference occurs:

[0041] The quadrilateral frame body 100 includes an upper frame plate 105 and a lower frame plate 106, the upper frame plate 105 is parallel to the upper side of the lower frame plate 106, the rotating ends of the upper frame plate 105 and the lower frame plate 106 are rotatably connected to the hinge seat 206 through a rotating shaft, and the lifting ends of the upper frame plate 105 and the lower frame plate 106 are rotatably connected to the swing arm head 300 through a rotating shaft. The upper frame plate 105, the lower frame plate 106, the swing arm head 300 and the hinge seat 206 form a parallelogram, so that the quadrilateral frame body 100 maintains the swing arm head 300 in a vertical state during the rotation process, thereby eliminating the problem of angle deflection caused by swinging;

[0042] Figure 5 As shown, the swing arm head 300, the upper shelf plate 105, the lower shelf plate 106 and the hinge seat 206 are the four sides of a parallelogram. Since the hinge seat 206 is always in a vertical state, and the upper shelf plate 105 and the lower shelf plate 106 have independent action points on their sides, when the lifting force acts on the lifting groove 103, the upper shelf plate 105 and the lower shelf plate 106 rotate around the hinge seat 206 at one end, and the swing arm head 300 connected to the other end of the upper shelf plate 105 and the lower shelf plate 106 will remain parallel to the hinge seat 206, so as to avoid the problem of the swing arm head 300 tilting during lifting, and ensure the stability of the goods. As shown in Figure 5, the free end will always maintain a parallel state with the fixed end;

[0043] Working principle: In actual use, the driving belt group 207 drives the lifting slide 203 and the lifting screw 201 to rotate relative to each other. Under the action of the thread, the lifting slide 203 will move up and down along the lifting slide 202, so as to obtain the lifting power; the lifting force here drives the power close to the end of the swing arm, and the power requirement for the driving force is lower. The upper shelf plate 105, the lower shelf plate 106, the swing arm head 300 and the articulated seat 206 constitute a parallelogram. The quadrilateral frame body is a parallelogram mechanism, which can ensure that the front end is level when the arm is swung, avoiding the problem of tilting when adjusting the height of the goods.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
