Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to a hydraulic height-adjustable self-moving scraper conveyor head and scraper conveyor. Background Technology

[0002] A scraper conveyor is a conveyor that uses a scraper chain to pull bulk materials through a trough.

[0003] Currently, the head and tail height adjustment and pushing of scraper conveyors mainly adopt the following structural forms: mechanical pad vertical height adjustment, hydraulic vertical height adjustment, wedge auxiliary device height adjustment, single manual pushing, hydraulic support pushing, etc.

[0004] The height adjustment and moving methods listed above each have their own drawbacks. For example, the vertical height adjustment of the mechanical pad is limited by the height of the pre-formed pad, and cannot be steplessly adjusted or finely adjusted when the roadway is uneven to make the machine head reach the appropriate height. Although the hydraulic vertical height adjustment can meet the stepless adjustment in the height direction, it cannot make angle adjustment and still requires external force to complete the movement of the unit. The wedge auxiliary device can produce angle adjustment, but the adjustment range in the height direction is limited, and it still requires external force to complete the movement.

[0005] For example, Chinese Patent Publication No. CN202121633435.1 discloses a hydraulic height-adjustable scraper conveyor pushing device (such as...).

[0036] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] Please see Figures 2 to 4 As shown, this utility model provides a hydraulically adjustable self-moving scraper conveyor head, comprising: a power unit 11, with a transfer machine tail section 21 arranged side-by-side on one side of the power unit 11; a head tail frame 61, vertically mounted on the transfer machine tail section 21 and connected to the power unit 11, the head tail frame 61 being equipped with a hydraulic system 71; an articulated self-moving height adjustment unit 41, located on one side of the head tail frame 61 and on the same straight line as the power unit 11, the articulated self-moving height adjustment unit 41 being used to adjust the height and angle of the head tail frame 61 and to drive the head tail frame 61 to move along the extension direction of the power unit 11; and a box-type pushing height adjustment unit 81, located on the other side of the head tail frame 61, the box-type pushing height adjustment unit 81 being used to adjust the height of the head tail frame 61.

[0038] The power unit 11 and the tail section 21 of the transfer machine are arranged side by side, which facilitates the vertical mounting of the head and tail frame 61 on the tail section 21. The articulated self-adjusting height unit 41 is then mounted on the head and tail frame 61. This articulated self-adjusting height unit 41 can adjust the height and angle of the head and tail frame 61, as well as move it forward and backward. At the same time, the box-type pushing height unit 81 is located on the other side of the head and tail frame 61, symmetrically arranged with the articulated self-adjusting height unit 41. This box-type pushing height unit 81 can also raise and lower the head and tail frame 61. In actual use, the articulated self-adjusting height unit 41 and the box-type pushing height unit 81 can be used alone or in combination.

[0039] Among them, the power unit 11 is connected to the head and tail frame 61 through the reducer stop, fixing pin 4102, and bolts;

[0040] The head and tail frame 61 is equipped with a left baffle 31, a right baffle 51, and a coal hopper. The left baffle 31 and the right baffle 51 are used to smoothly transport coal blocks into the coal hopper. The tail section 21 of the transfer machine is located below the head and tail frame 61 to collect the incoming material from the head and tail frame 61, and does not connect with other components.

[0041] In some optional embodiments, the articulated self-adjusting height unit 41 includes: an angle adjusting member, one end of which is connected to the head and tail frame 61, and the other end is provided with a bottom support platform 4104; a first height adjusting cylinder 4105, which is disposed in the bottom support platform 4104; a slide 4108, on which a slide seat 4107 is provided, the slide seat 4107 being hinged to the first height adjusting cylinder 4105, and a horizontal cylinder 4106 being disposed in the slide seat 4107, both the horizontal cylinder 4106 and the first height adjusting cylinder 4105 being connected to the hydraulic system 71.

[0042] The angle adjustment mechanism enables the conveyor head to be adjusted. A first height-adjusting cylinder 4105 is connected to a hydraulic system 71. The hydraulic system 71 controls the cylinder 4105 to lower, thus lowering the cylinder body and supporting the slide block 4107 and slide frame 4108 connected to the cylinder body. When the slide frame 4108 is supported on the ground, further hydraulic control extends the cylinder rod of the first height-adjusting cylinder 4105, raising the bottom support platform 4104 and adjusting its height.

[0043] During horizontal movement, the first height adjustment cylinder 4105 extends, allowing the slide 4108 to support the ground. After the slide 4108 supports the ground, the horizontal cylinder 4106 controls the forward and backward movement of the horizontal cylinder 4106, thereby driving the bottom support platform 4104 and the head and tail frames 61 connected to the bottom support platform 4104 to move back and forth. After the bottom support platform 4104 has moved, the slide 4108 supported on the ground is retracted, and the horizontal cylinder 4106 is controlled to drive the slide 4108 to move back and forth, thus entering the next movement cycle.

[0044] In some optional embodiments, the angle adjustment component includes: an upper hinge support 4101 connected to the head and tailstock 61; and a lower hinge support 4103 located below the upper hinge support 4101 and connected to the upper hinge support 4101 via a fixing pin 4102. The bottom of the lower hinge support 4103 is provided with a first box structure 4109, which is inserted into the bottom support platform 4104.

[0045] The upper hinge support 4101 connects the articulated self-adjusting height unit 41 to the head and tailstock 61. A lower hinge support 4103 is provided below the upper hinge support 4101. A fixing pin 4102 passes through the upper hinge support 4101 and the lower hinge support 4103, connecting them and enabling relative rotation. This allows for angle adjustment of the articulated self-adjusting height unit 41 relative to the head and tailstock 61.

[0046] In some optional embodiments, the first box structure 4109 has a first groove 4110 on its side wall and a first limiting pin 4111 in the first groove 4110, the first limiting pin 4111 passing through the first fixing block 4112 of the bottom support platform 4104.

[0047] By providing a first sliding groove 4110 on the side wall of the first box structure 4109, the first limiting pin 411 in the first sliding groove 4110 can be connected to the first fixing block 4112 on the bottom support platform 4104, thereby realizing the guiding function of the first box structure 4109 when it is raised and lowered.

[0048] The horizontal hydraulic cylinder 4106 has a bidirectional telescopic cylinder rod, which is hinged to the slide block 4107. This configuration allows for the forward and backward movement of the hinged self-adjusting height adjustment unit 41 and the head and tail frames 61.

[0049] In this embodiment, the slide 4108 is provided with a slide rail 4113, and the slide block 4107 moves within the slide rail 4113. The slide rail 4113 facilitates the movement of the slide block 4107 by the horizontal cylinder 4106, thus providing a guiding function for the movement of the slide block 4107.

[0050] In some optional embodiments, the box-type push-adjustment unit 81 includes: a sliding support 8102, which is connected to the head and tail frame 61, and a second box-type structure 4109 is provided at the bottom of the sliding support 8102; a bottom support 8105, which is located below the sliding support 8102, a second adjustment cylinder 8104 is located inside the bottom support 8105, and the second box-type structure 8106 is inserted into the bottom support 8105.

[0051] The box-type push-and-adjust unit 81 is connected to the head and tail frame 61 via a sliding support seat 8102, and is connected to the bottom support seat 8105 via a second box-type structure 8106. When height adjustment is required, the bottom support seat 8105 provides bottom support for the box-type push-and-adjust unit 81, and the hydraulic system 71 supplies fluid to the second height adjustment cylinder 8104. The cylinder rod of the second height adjustment cylinder 8104 extends to lift the sliding support seat 8102 and adjust it to a suitable height.

[0052] In some optional embodiments, the second box structure 8106 has a second sliding groove 8107 on its side wall, and a second limiting pin 8103 is provided in the second sliding groove 8107, the second limiting pin 8103 passing through the second fixing block 8018 of the bottom support 8105.

[0053] The second box-type structure 8106, the second sliding groove 8107, and the second limiting pin 8103 at the lower part of the sliding support 8102 ensure stability when the sliding support 8102 is adjusted up or down. The bottom support 8105 provides an external customized interface for connecting and moving hydraulic supports, single columns, etc.

[0054] Meanwhile, the box-type push-adjustment unit 81 also includes an upper connecting plate 8101, which is located between the sliding support seat 8102 and the head and tail frame 61, thereby realizing the connection between the upper connecting plate 8101 and the head and tail frame 61.

[0055] The first height adjustment cylinder 4105 and the second height adjustment cylinder 8104 have a self-locking function. After the height is adjusted, the self-locking function can be activated. Alternatively, the space created by the first height adjustment cylinder 4105 and the second height adjustment cylinder 8104 can be filled with a pad to prevent the first height adjustment cylinder 4105 and the second height adjustment cylinder 8104 from descending.

[0056] The specific working principle of the hydraulic height-adjustable self-moving scraper conveyor head:

[0057] When the articulated self-adjusting height unit 41 needs to be adjusted in height, the hydraulic system 71 controls the first height-adjusting cylinder 4105 to be filled with fluid, causing the cylinder body of the first height-adjusting cylinder 4105 to descend, thereby grounding and supporting the slide 4107 and the slide frame 4108 connected to the cylinder body. When the slide frame 4108 is supported on the ground, further fluid is added to control the extension of the cylinder rod of the first height-adjusting cylinder 4105, causing the cylinder rod to support the bottom support platform 4104 to be raised, thereby adjusting the height of the bottom support platform 4104.

[0058] During horizontal movement, the first height adjustment cylinder 4105 extends, allowing the slide 4108 to support the ground. After the slide 4108 supports the ground, the horizontal cylinder 4106 controls the forward and backward movement of the horizontal cylinder 4106, thereby driving the bottom support platform 4104 and the head and tail frames 61 connected to the bottom support platform 4104 to move back and forth. After the bottom support platform 4104 has moved, the slide 4108 supported on the ground is retracted, and the horizontal cylinder 4106 is controlled to drive the slide 4108 to move back and forth, thus entering the next movement cycle.

[0059] When the box-type sliding height adjustment unit 81 needs to be raised, the bottom support 8105 provides bottom support, and the hydraulic system 71 controls the second height adjustment cylinder 8104 to inject fluid. The cylinder rod of the second height adjustment cylinder 8104 extends, raising the sliding support 8102 to a suitable height. The second box-type structure 8016, the second slide groove 8107, and the second limit pin 8103 at the bottom of the sliding support 8102 ensure the stability of the bottom support 8105 during height adjustment. The bottom support 8105 provides an external customized interface for connection and movement of hydraulic supports, single columns, etc.

[0060] This utility model also provides a hydraulically adjustable self-moving scraper conveyor, including the aforementioned hydraulically adjustable self-moving scraper conveyor head.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
