Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to an unloading frame with a telescopic head. Background Art

[0002] Belt conveyor is a continuous transport machine that uses conveyor belt as traction and load-bearing component. The conveyor belt is wound around the head drive roller and each redirection roller to form a closed loop. The upper and lower conveyor belts are supported by rollers to limit the deflection and sag of the conveyor belt between two adjacent roller groups. The tensioning device provides the required tension for the normal operation of the belt conveyor. When the belt conveyor is working normally, the drive device drives the drive roller through the rigid and flexible coupling, and the conveyor belt is operated through the friction between the drive roller and the conveyor belt. The materials on the conveyor belt move synchronously with the conveyor belt.

[0003] Belt conveyors are usually unloaded at the end, with fixed unloading points and no freedom to move forward. They can only be used by overlapping one conveyor. Traditional belt conveyors face severe challenges in shipping, especially when encountering complex geological conditions and multi-system shipping. When another conveyor is needed, the overlapping conveyor needs to be dismantled as a whole and reinstalled before it can continue to work, which is time-consuming and labor-intensive.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0031] like Figure 1 As shown in FIG. 6 , the utility model provides an unloading rack with a telescopic head, comprising a telescopic head 2, a supporting frame 1, and a cylinder 3. The telescopic head 2 is slidably arranged at the front end opening of the supporting frame 1. The telescopic head 2 and the supporting frame 1 are connected by two cylinders 3. The extension and retraction of the telescopic mechanism on the supporting frame 1 are controlled by the extension and retraction of the cylinder 3.

[0032] The support frame 1 includes a base frame 101, a left support column 102, a right support column 103, a left longitudinal beam 104, a right longitudinal beam 105, and a connecting cross beam 106. The base frame 101 is kept horizontally arranged, the left support column 102 and the right support column 103 are kept vertically, and the left support column 102 and the right support column 103 are arranged at the left edge and the right edge of the base frame 101 respectively; the left longitudinal beam 104 is fixedly arranged at the upper end of a row of left support columns 102, and the right longitudinal beam 105 is fixedly arranged at the upper end of a row of right support columns 103, and the left longitudinal beam 104 and the right longitudinal beam 105 are both arranged horizontally along the front-back direction, and the left longitudinal beam 104 and the right longitudinal beam 105 are kept left-right symmetrical. A connecting cross beam 106 is fixedly arranged between the upper end of the left support column 102 on the rear side and the upper end of the right support column 103 on the rear side, and the connecting cross beam 106 is arranged horizontally along the left-right direction.

[0033] A slide groove 107 is respectively provided at the front end of the side surface where the left longitudinal beam 104 and the right longitudinal beam 105 are close to each other, and the slide groove 107 extends along the front and rear horizontal direction; a top plate 108 and a bottom plate 109 are respectively fixedly provided on the top and bottom surfaces inside the slide groove 107, and the top plate 108 and the bottom plate 109 are kept horizontal.

[0034] A vertical baffle 110 is fixedly disposed on the front ends of the upper end faces of the left longitudinal beam 104 and the right longitudinal beam 105 , respectively. The baffle 110 is horizontally extended along the front-rear direction.

[0035] The telescopic head 2 includes a left fixed beam 201 , a right fixed beam 202 , a connecting beam 203 , an unloading roller 204 , a belt-supporting roller 206 , a roller support frame 205 , a walking wheel 207 , and a guide wheel 208 .

[0036] The left fixed beam 201 and the right fixed beam 202 are symmetrical and both are arranged horizontally along the front-back direction. The left fixed beam 201 and the right fixed beam 202 are fixedly connected by a connecting beam 203, and the connecting beam 203 is arranged horizontally along the left-right direction.

[0037] Two left-right symmetrical oil cylinders 3 are arranged between the connecting beam 203 of the telescopic mechanism and the connecting cross beam 106 of the supporting frame 1. The piston rods of the oil cylinders 3 face horizontally to the front, one end of the cylinder bottom of the oil cylinder 3 is hinged to the connecting cross beam 106, and one end of the piston cylinder of the oil cylinder 3 is hinged to the connecting beam 203.

[0038] An unloading roller 204 is rotatably disposed between the front ends of the left fixed beam 201 and the right fixed beam 202. A row of roller racks 205 are fixedly disposed between the upper end surfaces of the left fixed beam 201 and the right fixed beam 202, and rollers are rotatably disposed on the roller racks 205. A belt-carrying roller 206 is rotatably disposed between the lower end surfaces of the left fixed beam 201 and the right fixed beam 202.

[0039] A row of running wheels 207 are rotatably arranged on the end faces of the left fixed beam 201 and the right fixed beam 202 away from each other. The running wheels 207 are arranged along the front-to-back horizontal direction, and the rotation axis of the running wheels 207 is horizontally arranged along the left-to-right direction.

[0040] A row of guide wheels 208 are rotatably disposed on the upper end surfaces of the left fixed beam 201 and the right fixed beam 202 . The guide wheels 208 are arranged along the front-to-back direction, and the rotation axes of the guide wheels 208 are disposed along the vertical direction.

[0041] The left and right rows of running wheels 207 are respectively located inside the slide groove 107 of the left longitudinal beam 104 and the right longitudinal beam 105. The running wheels 207 are in rolling contact with the bottom plate 109 inside the slide groove 107. The outer diameter of the running wheels 207 is smaller than the distance between the top plate 108 and the bottom plate 109 of the slide groove 107.

[0042] The left and right rows of guide wheels 208 are in rolling contact with the baffles 110 on the left and right sides respectively.

[0043] The working principle of the utility model is:

[0044] When the piston rod of the oil cylinder 3 extends, the telescopic head 2 is driven to extend outward from the front opening of the support frame 1; when the piston rod of the oil cylinder 3 is retracted, the telescopic mechanism is driven to be retracted from the outside of the front opening of the support frame 1. The telescopic head 2 is moved forward or backward by the extension and retraction of the oil cylinder 3, thereby changing the actual unloading point.

[0045] The top plate 108 and the bottom plate 109 inside the slide groove 107 are used to suppress the up and down swing of the telescopic head 2 during the movement.

[0046] When the telescopic head 2 is extended forward, the front running wheel 207 is in rolling contact with the top plate 108 inside the slide groove 107, thereby suppressing the front side of the telescopic head 2 from tilting upward. When the telescopic head 2 continues to be extended forward, the running wheel 207 is always in rolling contact with the top plate 108 inside the slide groove 107, reducing the friction resistance of the telescopic head 2 during the forward extension process, so that the telescopic head 2 remains smooth during the forward extension process.

[0047] When the telescopic head 2 is retracted backward, the front running wheel 207 is in rolling contact with the bottom plate 109 inside the slide groove 107, thereby suppressing the front side of the telescopic head 2 from tilting downward. When the telescopic head 2 continues to be retracted backward, the running wheel 207 is always in rolling contact with the bottom plate 109 inside the slide groove 107, reducing the friction resistance of the telescopic head 2 during the process of being retracted backward, so that the telescopic head 2 remains smooth during the process of being retracted backward.

[0048] When the telescopic head 2 is extended forward or retracted backward, the guide wheels 208 on both sides always maintain rolling contact with the baffles 110 on both sides, thereby limiting the left and right movement of the telescopic head 2 and further suppressing the left and right swing of the telescopic head 2.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
