Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more particularly to a transfer belt conveyor. Background Technology

[0002] According to the process route of the open-pit mine working face, the open-pit mine transfer belt conveyor needs to be moved multiple times. The existing transfer belt conveyor has two transfer methods: transfer machine and bulldozer. When the bulldozer is used, the bulldozer directly pushes each unit body horizontally laterally.

[0003] When using a bulldozer, the bulldozer directly pushes each unit body horizontally. However, because the bulldozer's pushing step distance is unstable, and the entire unit body moves when it encounters the ground or obstacles during the movement, it hinders the horizontal movement of the device and reduces the accuracy of horizontal movement. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the entire unit moves when it encounters the ground or obstacles during movement, thus hindering the horizontal movement of the device, and to propose a transfer belt conveyor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a shifting belt conveyor, including a unit body side frame, on which a lower idler roller group is installed, and both ends of the unit body side frame are connected to a side shifting mechanism, and a locking mechanism is installed at the upper end of each side shifting mechanism; The locking mechanism includes a fixed bracket, which is fixedly connected to a lateral shifting mechanism. A second support is fixedly connected to the upper end of the fixed bracket, and a second lifting cylinder is connected to the bottom end of the second support via a fourth connecting pin. The telescopic end of the second lifting cylinder is connected to a second anchor rod via a fifth connecting pin. The second anchor rod passes through the fixed bracket and is inserted into the ground to prevent the lateral shifting mechanism from hitting the ground or obstacles and causing the entire unit body to move when it extends outward.

[0006] Preferably, the lower support roller assembly includes two symmetrically arranged locking plates with top screws. Each locking plate with top screws is connected to the side frame of the unit body by a top screw bolt. Each locking plate with top screws is connected to a circular chain. One end of each circular chain is rotatably connected to a lower support roller. The opposite sides of the two lower support rollers are connected by a first hinge joint.

[0007] Preferably, the two lower rollers are arranged in a V-shape.

[0008] Preferably, the lateral shifting mechanism includes a pushing bracket, which is slidably sleeved onto the side frame of the unit body. A pushing cylinder is installed inside the side frame of the unit body. The telescopic end of the pushing cylinder is connected to the pushing bracket via a third connecting pin. A first support is installed at the upper end of the pushing bracket. A first lifting cylinder is connected to the bottom end of the first support via a first connecting pin. The telescopic end of the first lifting cylinder is connected to a first anchor rod body via a second connecting pin. The first anchor rod body passes through the pushing bracket. One end of the pushing bracket is connected to a fixed bracket.

[0009] Preferably, the first support and the pushing bracket are an integral structure.

[0010] The advantages of the shifting belt conveyor proposed in this invention are as follows: When moving via the transfer belt conveyor, the operator starts the hydraulic station by controlling the electrical control box, causing the second lifting cylinder to extend downwards. This, in turn, pushes the second anchor rod into the ground through the fifth connecting pin, preventing the side-shifting mechanism from hitting the ground or obstacles and causing the entire unit body to move. This ensures that the horizontal movement of the device is not hindered and improves the accuracy of horizontal movement. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] Example 1: Refer to Figure 1-4 The shifting belt conveyor includes a unit body side frame 1, with longitudinal beams 3 installed on both sides of the upper end of the unit body side frame 1. Several upper idler roller groups 4 are evenly spaced between the two longitudinal beams 3 along the length direction. Lower idler roller groups 2 are installed on the unit body side frame 1. Connecting beams 5 for improving strength are fixedly connected to the unit body side frame 1. Side shifting mechanisms 8 are connected to both ends of the unit body side frame 1. A locking mechanism 9 is installed at the upper end of each side shifting mechanism 8. An electrical control box 6 is provided on one side of the unit body side frame 1, and a hydraulic station 7 is provided on the other side of the unit body side frame 1. Reference Figure 3 The lateral shifting mechanism 8 includes a pushing bracket 86, which is slidably sleeved onto the side frame 1 of the unit body. A pushing cylinder 88 is installed inside the side frame 1 of the unit body. The telescopic end of the pushing cylinder 88 is connected to the pushing bracket 86 through a third connecting pin 87. A first support 81 is installed at the upper end of the pushing bracket 86. The first support 81 and the pushing bracket 86 are an integral structure. The bottom end of the first support 81 is connected to a first lifting cylinder 83 through a first connecting pin 82. The telescopic end of the first lifting cylinder 83 is connected to a first anchor rod body 85 through a second connecting pin 84. The first anchor rod body 85 passes through the pushing bracket 86. One end of the pushing bracket 86 is connected to a locking mechanism 9. Reference Figure 4The locking mechanism 9 includes a fixed bracket 96, which is fixedly connected to a push bracket 86. A second support 91 is fixedly connected to the upper end of the fixed bracket 96. The second support 91 and the fixed bracket 96 are an integral structure. A second lifting cylinder 93 is connected to the bottom end of the second support 91 through a fourth connecting pin 92. A second anchor rod body 95 is connected to the telescopic end of the second lifting cylinder 93 through a fifth connecting pin 94. The second anchor rod body 95 passes through the fixed bracket 96.

[0015] Working principle: When the shifting belt conveyor moves to the left, the operator starts the hydraulic station 7 by controlling the electrical control box 6, so that the second lifting cylinder 93 extends downward, thereby pushing the second anchor body 95 into the ground through the fifth connecting pin 94. This prevents the side shifting mechanism 8 from hitting the ground or obstacles when it extends outward, thus preventing the entire unit body from moving. This will not hinder the horizontal movement of the device and improve the horizontal movement accuracy. The control box 6 starts the push cylinder 88 to extend outward. When it extends to the designated position, the second lifting cylinder 93 is activated to drive the second anchor body 95 to retract. At the same time, the first lifting cylinder 83 is activated. The first lifting cylinder 83 drives the first anchor body 85 to insert into the ground through the second connecting pin 84. The push cylinder 88 is activated to retract. After the push cylinder 88 retracts, it drags the unit body to move horizontally to the left. The first lifting cylinder 83 drives the first anchor body 85 back to its position. One horizontal movement to the left is completed. When the shifting belt conveyor moves to the right, the first lifting cylinder 83 is activated. The first lifting cylinder 83 pushes the first anchor bolt 85 into the ground through the second connecting pin 84. Then, the pushing cylinder 88 extends, pushing the unit body to move horizontally to the right. After the lateral movement is completed, the first lifting cylinder 83 retracts, and at the same time, the second lifting cylinder 93 extends downward, thereby pushing the second anchor bolt 95 into the ground. The next step is to retract the pushing cylinder 88, and finally, the second lifting cylinder 93 drives the anchor bolt 95 back to its original position. One horizontal lateral movement to the right is completed, realizing the quantification of the horizontal lateral movement of the shifting belt conveyor, improving the accuracy of the horizontal lateral movement, and enhancing its safety performance.

[0016] Example 2: When the lower tape shifts, it is inconvenient to correct the deviation. Refer to... Figure 1As another preferred embodiment of the present invention, the difference from embodiment 1 is that the lower idler roller group 2 includes two symmetrically arranged locking plates 24 with top screws. Each locking plate 24 with top screws is connected to the side frame 1 of the unit body by a top screw bolt 25. Each locking plate 24 with top screws is connected to a circular chain 23. One end of each circular chain 23 is rotatably connected to a lower idler roller 21. The opposite sides of the two lower idler rollers 21 are connected by a first hinge joint 22. The two lower idler rollers 21 are distributed in a V-shape. When it is necessary to correct the lower conveyor belt, the top screw bolt 25 is adjusted to move the locking plate 24 with top screws. The locking plate 24 with top screws drives the circular chain 23 to move. At this time, one side of the lower idler roller group 2 can be moved to achieve the purpose of correction.

[0017] Example 3: The idler roller has a low service life due to friction, refer to Figure 5 As another preferred embodiment of the present invention, the difference from embodiment 1 is that the upper idler roller group 4 includes two symmetrically arranged meshing insert hooks 41. Each meshing insert hook 41 is connected to the longitudinal beam 3. Each meshing insert hook 41 is attached to a connecting ring 42. One end of each connecting ring 42 is connected to a long idler roller 44 through a second hinge joint 43. Several short idler rollers 46 are provided between the two long idler rollers 44. Both the long idler rollers 44 and the short idler rollers 46 are steel idler rollers. The several short idler rollers 46 are connected to each other through a fourth hinge joint 47. The short idler rollers 46 are connected to the long idler rollers 44 through a third hinge joint 45. During the material conveying process, the material is basically piled up in the middle position. The middle idler roller is subjected to the greatest force. The use of several short idler rollers 46 in the middle reduces the force on a single idler roller and improves the service life of the idler roller. In addition, the long idler rollers 44 on both sides are conducive to the smooth operation of the conveyor belt and prevents the problem of the edge of the conveyor belt getting caught in the gap of the idler roller group when the conveyor belt runs off-center.

[0018] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
