DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0024] like Figures 1 to 5As shown, a frame 2 is fixedly provided below the conveyor body 1. The conveyor body 1 can be a conventional conveyor such as a belt conveyor, a roller conveyor, a chain conveyor, etc. In this embodiment, a roller conveyor is taken as an example for explanation. The frame 2 is a rectangular frame surrounded by aluminum profiles, and is tightly connected to the lower surface of the conveyor body 1. A support leg 4 connected by a bracket 3 is provided below the frame 2. The leg 4 is used to support the frame 2 and the conveyor body 1. The frame 2 and the support leg 4 are hingedly connected. Specifically, a first bearing seat 5 is provided below the frame 2, and a second bearing seat 6 is provided above the leg 4, wherein the axes of the first bearing seat 5 and the second bearing seat 6 are coaxially arranged, and a connecting shaft 7 passes through the first bearing seat 5 and the second bearing seat 6, thereby hingedly connecting the frame 2 and the bracket 3, and the frame 2 can rotate around the connecting shaft 7 relative to the leg 4 at a certain angle.

[0025] The fixed end of the cylinder 8 is fixedly connected to the bracket 3, and the free end of the cylinder 8 is hingedly connected to the first side of the frame 2. The first side is one of the two sides of the conveying direction of the conveyor line body 1, specifically, the side where the operator is located, so that the conveyor line body 1 is tilted toward the side close to the operator, which is convenient for the operator to operate. When the free end of the cylinder 8 is in the pushed-out state, the conveying surface of the conveyor line body 1 is a horizontal plane parallel to the ground, that is, the conveyor line body 1 is in a state such as Figure 4 In the conventional conveying state shown in FIG. 1 , when the free end of the cylinder 8 is in a contracted state, the free end of the cylinder 8 drives the frame 2 and the first side of the conveying line body 1 to rotate around the connecting shaft 7 toward the ground, and the conveying line body 1 is in a state as shown in FIG. Figure 5 In the tilted operating state shown, the cylinder 8 selected in this embodiment is a cylinder 8 that can clamp the piston rod at any position, which is convenient for accurate positioning of the free end of the cylinder 8 and has the ability to withstand a certain force.

[0026] In some embodiments, a tilt limit seat 9 is provided on the first side of the support leg 4, and the upward side of the tilt limit seat 9 is a slope, and its inclination angle is the same as the inclination angle of the conveyor line body 1 in the tilted operating state. When the conveyor line body 1 is in the operating state driven by the cylinder 8, the lower surface of the frame 2 below the conveyor line body 1 contacts the slope of the tilt limit seat 9, thereby limiting the tilt angle of the conveyor line body 1 to prevent the possibility of over-rotation. A horizontal limit seat 10 is provided on the second side of the support leg 4, and the horizontal surface of the upward side of the horizontal limit seat 10 is horizontal. When the conveyor line body 1 is in the normal conveying state driven by the cylinder 8, the lower surface of the frame 2 below the conveyor line body 1 contacts the horizontal surface of the horizontal limit seat 10 to prevent the possibility of over-rotation during the resetting process. At the same time, the horizontal limit seat 10 plays a certain horizontal supporting role on the frame 2.

[0027] In some embodiments, the free end of the cylinder 8 is hingedly connected to the first side of the frame 2 via a floating joint 11, one end of the floating joint 11 is hingedly connected to the bottom surface of the first side of the frame 2 via a connecting piece 12, and the other end of the floating joint 11 is floatingly connected to the free end of the cylinder 8. The floating connection protects the free end of the cylinder 8.

[0028] In some embodiments, two nitrogen springs 13 are used to connect the bracket 3 and the frame 2. The fixed end of the nitrogen spring 13 is hingedly connected to the bracket 3, and the free end of the nitrogen spring 13 is hingedly connected to the lower part of the first side of the frame 2. The nitrogen spring 13 is used to provide damping to ensure that the free end of the cylinder 8 is extended and retracted to drive the conveyor line body 1 to rotate stably.

[0029] In some embodiments, the connecting shaft 7 is a reducing shaft, including a first end 701, a second end 702 and a third end 703 connected in sequence, wherein the radius of the first end 701 is greater than that of the second end 702, the radius of the second end 702 is greater than that of the third end 703, the radius of the first end 701 is greater than the radius of the first bearing seat 5, the radius of the second end 702 matches the first bearing seat 5, the radius of the third end 703 matches the second bearing seat 6, the third end 703 of the connecting shaft 7 is inserted from the direction of the first bearing seat 5, and passes through the second bearing seat to complete the connection, so that the first end 701 is limited to the outside of the first bearing seat 5, the second end 702 is placed in the first bearing seat 5, and the third end 703 is placed in the second bearing seat 6.

[0030] In some embodiments, a thrust ball bearing 14 is provided between the first bearing seat 5 and the second bearing seat 6. The thrust ball bearing 14 is used to bear the circumferential load. The thrust ball bearing 14 is coaxially arranged between the first bearing seat 5 and the second bearing seat 6. The connecting shaft 7 passes through the first bearing seat 5, the thrust ball bearing 14 and the second bearing seat 6 in sequence. The thrust ball bearing 14 plays a role in reducing friction between the first bearing seat 5 and the second bearing seat 6. To ensure that the two sides of the thrust ball bearing 14 are respectively in contact with the first bearing seat 5 and the second bearing seat 6 In the connected state, a thrust limiting mechanism is additionally provided, specifically, a downward connecting block 15 is provided under the frame 2, and a limiting screw 16 is sleeved on the connecting block 15, and one end of the limiting screw 16 abuts against the end face of the first end 701 of the connecting shaft 7. By adjusting the position of the limiting screw 16 relative to the position of the connecting block 15, the limiting screw 16 provides pressure on the end face of the first end 701 of the connecting shaft 7, so that the first bearing seat 5 is pressed relative to the second bearing seat 6, ensuring that the thrust ball bearing 14 is in an abutting state with the first bearing seat 5 and the second bearing seat 6.

[0031] In some embodiments, a blocking bracket 17 is provided on the first side of the frame 2. The blocking bracket 17 is an L-shaped plate, one end of which is fixedly connected to the frame 2, and the length direction of the other end is perpendicular to the conveying surface direction of the conveying line body 1 and higher than the conveying surface of the conveying line body 1. The two blocking brackets 17 are arranged at intervals and fixedly connected by a connecting rod 18. The blocking bracket 17 is provided with a tray support wheel 19 at the height of the tray. The height of the tray support wheel 19 relative to the conveying surface of the conveying line body 1 is the same as the height of the side edge of the tray on the conveying line body 1. The tray support wheel 19 is used to support the tray in an inclined state to prevent the tray from falling or sliding out of the conveying line body 1. The blocking bracket 17 is used to support the load above the tray in an inclined state to prevent the load from falling or sliding out of the conveying line body 1. It should be noted that the height and shape of the blocking bracket 17 and the tray support wheel 19 can be adjusted according to the actual working conditions. The function is to block the tray and the load, which is not limited here.

[0032] In some embodiments, a horizontal position detection sensor 20 and an inclined position detection sensor 21 are respectively provided at one end of the frame 2. The horizontal position detection sensor 20 is used to detect whether the conveying surface of the conveying line body 1 is in a horizontal state, and generate a corresponding detection signal. The inclined position detection sensor 21 is used to detect whether the conveying line body 1 is in a preset inclination angle, that is, in an operating state, and generate a detection signal. The telescopic state of the free end of the cylinder 8 is controlled according to the detection signal, thereby completing the switching of the horizontal state and the operating state of the conveying line body 1.

[0033] In some embodiments, a stopper 22 and a backstop 23 are provided at the preset stop operation position of the pallet on the conveying line 1, respectively, wherein the stopper 22 blocks one end of the pallet along the conveying direction to stop the pallet at the preset stop operation position, and the backstop 23 contacts the other end of the pallet along the conveying direction to prevent rebound from causing the position of the pallet to change, thereby limiting the pallet to the preset stop operation position, which is convenient for subsequent tilting of the conveying line 1 and operations on the load on the pallet.

[0034] The working principle of this application is explained below.

[0035] The free end of the cylinder 8 is in an extended state, and the conveyor line body 1 is in a normal state with the conveying surface horizontal. The pallet carrying the load is placed on the conveyor line body 1 and transported along the conveying direction. After reaching the preset stop operation position, it is limited and stopped by the stopper 22 and the check valve 23. At this time, the free end of the cylinder 8 contracts, driving the conveyor line body 1 to tilt toward the side where the operator is located. The pallet and the load are tilted to a preset angle along with the conveyor line body 1 and are blocked by the blocking bracket 17. At this time, the load is in an inclined position facing the operator, which makes it easier for the operator to perform processing operations on the load. When the operator completes the action, the free end of the cylinder 8 extends out, and the load is reset to a horizontal position along with the pallet and the conveyor line body 1. The stopper 22 is in a release state, and the load continues to be transported along the conveyor line body 1 along with the pallet. A set of actions is completed as described above.
