Description

Technical Field

[0001] The utility model relates to the technical field of overhead conveyor lines, in particular to a conveyor line end blocker. Background Art

[0002] In an overhead conveyor line, when a train set and a spreader enter or are about to enter a movable conveyor track, it is necessary to block the train set on the broken rail and the movable rail to ensure that the train set is in a safe state. Traditional blockers are driven by horizontally distributed drive devices, which can drive the blocker to move to the conveying path of the trolley to block the trolley. However, this method occupies a large horizontal space, especially in an overhead conveyor line. The installation of these drive devices is difficult and expensive.

[0003] At the same time, most blockers will not block the trolley when subjected to natural force. When a power outage occurs, the trolley will not be blocked, posing a safety hazard.

[0004] To this end, we propose a conveyor line end blocker. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a conveyor line end blocker, which uses a push frame that moves up and down to control the swing of the block, and can convert the horizontal driving force into a vertical driving force to control the blocking or release of the mobile cart.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] Conveyor line end stopper, including:

[0008] a connecting block, in which a rotating shaft is provided;

[0009] The stopper is fixedly mounted on one end of the rotating shaft and comprises two L-shaped swing arms. Under the action of gravity alone, one of the swing arms limits the movement of the trolley.

[0010] a rotating arm fixedly disposed at the other end of the rotating shaft;

[0011] A driving rod is connected to the rotating arm, and the other end of the driving rod is connected to a bearing;

[0012] The push frame has a "C"-shaped structure and its outer wall fits the bearing. The push frame is driven by a driving device to achieve vertical lifting and lowering, and drives the driving rod to achieve horizontal swing, and then actively controls the swing of the block to achieve blocking or release of the traveling trolley.

[0013] It is further characterized by:

[0014] The connecting block is fixed on the mounting frame.

[0015] The stopper and the rotating arm are both fixedly connected to the rotating shaft via positioning pins.

[0016] A buffer block is connected to the swing arm used to contact the walking trolley, and the length of the swing arm on the other side is slightly longer, so that the two swing arms are symmetrically distributed along the vertical line under the action of gravity.

[0017] The driving rods are distributed along the direction of the conveying track.

[0018] The push frame includes three sections, the middle section is vertically distributed, and the upper and lower sections are respectively inclined. When the stop block is in an unstressed state, the bearing is located at the uppermost / lowermost end of the push frame.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model has a compact and reasonable structure and is easy to operate. A push frame that moves up and down controls the swing of the block, which can convert the horizontal driving force into a vertical driving force, and controls the blocking or release of the mobile trolley. It can block the traveling trolley in an unstressed state, and can also block the traveling trolley in a power-off state, avoiding hidden dangers caused by untimely blocking. Moreover, by arranging three sections on the push frame, it is more convenient to judge the position of the block.

[0021] In addition, the utility model adopts a vertical drive mode, which is better arranged when targeting aerial conveyor lines, greatly reducing space occupancy, improving space utilization, and the overall structure is more stable. The mounting bracket can be installed on the side wall of the conveying track, avoiding the need to install a horizontal bracket during horizontal drive. Therefore, this embodiment can improve space utilization and the overall structure is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown - Figure 5 As shown, this embodiment discloses a conveyor line end blocker for blocking the traveling trolley 6 on the conveying track 11, including a connecting block 2, a block 4, a rotating arm 3, a driving rod 8 and a push frame 1. When the block 4 is not subjected to force, it is in a state of blocking the traveling trolley 6, wherein the push frame 1 is driven by a driving device to move up and down. As the push frame 1 moves up and down, it can drive the driving rod 8 to swing horizontally, thereby driving the block 4 to swing through the rotating arm 3 to block or release the traveling trolley 6.

[0031] Among them are specific;

[0032] The connecting block 2 is fixed on the mounting frame 10, and a rotating shaft is provided in the connecting block 2;

[0033] The two ends of the rotating shaft are fixedly connected with a stopper 4 and a rotating arm 3 respectively;

[0034] The block 4 includes two L-shaped swing arms. Under the action of gravity alone, one of the swing arms limits the movement of the walking trolley 6. The swing arm used to contact the walking trolley 6 is connected to a buffer block 5 to cushion the impact force of the walking trolley 6. The length of the swing arm on the other side that is not connected to the buffer block 5 is slightly longer, so that the two swing arms are symmetrically distributed along the vertical line under the action of gravity, which can just block the travel path of the walking trolley 6 to achieve a blocking effect.

[0035] The rotating arm 3 is coaxially connected to the stopper 4 and is used to drive the stopper 4 to rotate;

[0036] The lower end of the rotating arm 3 is connected to a driving rod 8, and the other end of the driving rod 8 is connected to a bearing 7, and the bearing 7 is rotatably fitted on the push frame 1;

[0037] The push frame 1 is a "C" shaped structure, specifically divided into three sections, the middle section is vertically distributed, the upper and lower sections are inclined, and when the stopper 4 is in the unstressed state, the bearing 7 is located at the upper / lower end of the push frame 1; by moving the push frame 1 up and down, the bearing 7 can fit on the middle section or the upper and lower sections, such as Figure 3-Figure 5 As shown, Figure 4 and Figure 5The bearings 7 are in contact with the upper and lower oblique edges of the push frame 1. At this time, the bearings 7 are not subjected to the pushing force of the push frame 1, and the block 4 blocks the traveling trolley 6 under natural gravity.

[0038] In this embodiment, a push frame 1 that moves up and down is used to control the swing of the block 4, which can convert the horizontal driving force into a vertical driving force. It is better arranged when targeting an aerial conveyor line and greatly reduces the space occupancy. Since it is an aerial conveyor line, if a planar driving device is used, it will be difficult to install and the cost will be high. The present invention adopts a vertical driving method, and the mounting bracket can be installed on the side wall of the conveying track 11, avoiding the need to install a horizontal bracket during horizontal driving. Therefore, this embodiment can improve space utilization, and the overall structure is more stable. It can block the walking trolley 6 when it is not under stress, and it can also block the walking trolley 6 when the power is off, avoiding the hidden dangers caused by untimely blocking, and by setting three sections on the push frame 1, it is more convenient to judge the position of the block 4.

[0039] like Figure 3 As shown, when the push frame 1 moves up and down, the bearing 7 is located on the vertical section of the push frame 1. At this time, the push frame 1 can block the bearing 7 to one side, thereby achieving a small swing of the block 4, and then the block 4 is freed from the obstruction of the walking trolley 6.

[0040] The outer wall fits with the bearing 7, and the push frame 1 is driven by the driving device to achieve vertical lifting and lowering, and drives the driving rod 8 to achieve horizontal swing, and then actively controls the swing of the block 4 to achieve blocking or release of the walking trolley 6.

[0041] The stopper 4 and the rotating arm 3 are both fixedly connected to the rotating shaft via a positioning pin 9, thereby improving the fixing effect.

[0042] The driving rods 8 are distributed along the direction of the conveying track 11, which can further optimize the spatial layout.

[0043] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
