Description

Technical Field

[0001] The utility model belongs to the technical field of belt-type transfer machines, and particularly relates to a belt picking device at the tail of a machine. Background Art

[0002] When the self-moving tail of the belt transfer machine and the main transport belt conveyor are used in conjunction with each other, as the anchor driller continues to advance, the belt transfer machine and the anchor driller move forward synchronously. When the belt transfer machine completes a lap stroke, the self-moving tail of the belt transfer machine steps forward one stroke. At this time, a gap is formed between the self-moving tail of the belt transfer machine and the main transport belt conveyor. The staff will place the corresponding intermediate frame under the main transport belt. When placing the intermediate frame, it is not easy to place the intermediate frame under the belt because the belt is in a loose state.

[0003] Specifically, during the movement of the self-moving tail of the belt transfer machine, the loose transmission belt, under the action of gravity, will bend downward and fill the empty position. Therefore, if the middle frame is placed in the empty position, the belt needs to be raised to expose the placement position.

[0004] In the actual construction process, due to the long length of the belt and the large gaps in the empty positions, it is difficult to fully lift the belt out of the empty positions during the lifting process. Therefore, in the actual work process, tools such as lifting rods are often needed. In the lifting process, due to certain requirements for the height of the lifting, it is not easy to fully lift the belt using the traditional manual operation tools. As a result, during the placement of the intermediate frame, the operating space is limited, making the operation more difficult.

[0005] At the same time, during the lifting process, the belt is easily misplaced. Specifically, after being raised, the belt is dropped onto the frame, and it is difficult to maintain the initial position of the belt. Once the belt is misplaced, the subsequent machine startup will cause serious misalignment, which makes subsequent correction more cumbersome and difficult. Utility Model Content

[0038] Example 1

[0039] like Figure 1-4 As shown, a tail belt lifting device includes a tail belt lifting frame 1. The specific structure of the tail belt lifting frame 1 is as follows: the tail belt lifting frame 1 includes a transverse frame part arranged at the front and rear sides, and a connecting frame part is welded to the left end of the transverse frame part.

[0040] The tail frame 1 of the belt lifting machine is equipped with an anti-deflection belt lifting roller mechanism 4; during the lifting process, the transmission belt is supported on the anti-deflection belt lifting roller mechanism 4, and the belt is prevented from being deflected during the lifting process by the anti-deflection belt lifting roller mechanism 4. In this way, the belt is protected from excessive deflection during the lifting process, which makes it more complicated to correct the position later.

[0041] Specifically, the belt-lifting prevention roller mechanism 4 includes a roller frame 3 fixedly mounted between the horizontal frame parts, and an upper roller member is mounted and connected to the roller frame 3. Specifically, the upper roller member includes two first upper buffer rollers 41 and a second upper buffer roller 42 arranged in a V shape; the upper roller member also includes a third upper buffer roller 43 corresponding to the first upper buffer roller and the second upper buffer roller 42; the first upper buffer roller 41, the second upper buffer roller 41, and the third upper buffer roller 43 are arranged in a triangular structure.

[0042] At the same time, roller seats corresponding to the first upper buffer roller 41, the second upper buffer roller 41, and the third upper buffer roller 43 are fixedly connected to the roller frame 3; the two ends of the first upper buffer roller 41, the second upper buffer roller 41, and the third upper buffer roller 43 are rotatably connected to the roller seats.

[0043] The first upper buffer roller 41, the second upper buffer roller 41, and the third upper buffer roller 43 arranged in the above structural layout form a triangular position structure, so as to fully support and limit the belt from the bottom and both sides, that is, the belt can be effectively supported and the two sides of the belt can be limited to avoid serious deviation of the belt during the lifting process. Through the above layout, the belt can still be located at the initial position after being lifted and dropped.

[0044] At the same time, in order to further prevent the belt from being deflected after being lifted, the anti-deflection belt roller mechanism 4 also includes a lower roller 44 assembled and connected between the ends of the transverse frame part. Specifically, roller seat plates corresponding to the lower roller 44 are respectively welded to the bottom of the transverse frame part, and both ends of the lower roller 44 are rotatably connected to the roller seat plates. After the belt is supported and inserted from the top of the lower roller 44, it is supported from the first upper buffer roller 41, the second upper buffer roller 41, and the third upper buffer roller 43.

[0045] Example 2

[0046] like Figure 1-4As shown, based on the structure of embodiment 1, the anti-deviation belt lifting roller mechanism 4 of this embodiment further includes an anti-deviation roller 2 assembled and connected to the transverse frame part at the front side, and the anti-deviation roller 2 abuts against the side edge of the transmission belt (according to the existing method, the bottom of the transverse frame part is fixed with a bottom bracket rotatably connected to the anti-deviation roller); the anti-deviation roller 2 is located at the rear side of the first upper buffer roller 41 and the third upper buffer roller 43. Under the abutment limit of the anti-deviation roller 2, the belt is further prevented from being deviated during the lifting process.

[0047] Example 3

[0048] like Figure 1-4 As shown, this embodiment is based on the structure of the first embodiment, and the structure of the first embodiment is used to keep the belt from being deviated during the lifting process. The lifting is achieved through this embodiment.

[0049] Specifically, the tail belt lifting device also includes a hydraulic lifting mechanism, which includes a plurality of hydraulic cylinders 5 hinged on the tail frame 1 of the belt lifting machine, and the hydraulic cylinders 5 and the tail frame 1 of the belt lifting machine are both hingedly mounted on the tail frame of the machine; during the belt lifting process, the hydraulic cylinder 5 pulls and swings the tail frame 1 of the belt lifting machine to a raised state, and the transmission belt supported on the anti-bias belt lifting roller mechanism 4 is lifted, and the belt remains in a tensioned state after being lifted.

[0050] Specifically, the top of the transverse frame part is respectively hinged to the upper hydraulic cylinder 5. The hinge method is: a pair of hinged ear plates 8 are welded on the transverse frame part, and the plunger rod of the hydraulic cylinder 5 is hinged between the hinged ear plates 8 through a fixed pin. At the same time, the cylinder barrel of the hydraulic cylinder 5 is respectively hinged to the upper fixed plate 6 (the cylinder barrel of the hydraulic cylinder 5 is welded with a hinge tongue, and the upper fixed plate 6 is welded with a pair of ear plates, and the hinge tongue is hinged between the ear plates through a pin shaft). At the same time, according to the existing method, the upper fixed plate is fixedly installed at the upper end position of the tail frame.

[0051] Correspondingly, the right end of the transverse frame part is hinged with a lower fixed plate 7, and the lower fixed plate 7 is fixedly installed at the lower end position of the tail frame (specifically, a pair of hinged plates are welded at the right end of the transverse frame part, and a hinged tongue plate is welded on the lower fixed plate, and the two are hinged by a pin shaft).

[0052] At the same time, the bottom of the horizontal frame part is fixedly assembled and connected to the supporting column.

[0053] Under normal conditions, the supporting columns are supported on the work surface and keep the entire device in a horizontal state. When it is necessary to raise the device, in order to protect the vacant position and place the intermediate frame in the installation recessed vacant position, the operator turns on the hydraulic cylinders 5 on both sides. Under the synchronous pulling of the hydraulic cylinders 5, the tail frame 1 of the belt lifting machine is raised. During the raising process, the belt supported on the frame is raised accordingly. As the belt is raised accordingly, the vacant position is exposed, thereby facilitating the installation of the intermediate frame.

[0054] In actual working process, the above structure is adopted. Since the lifting track is fixed, it is not easy to shake or deviate during the lifting process, and the belt also maintains sufficient stability, that is, the belt is lifted steadily along with the frame, and after lifting, it is lowered steadily and the belt returns to the initial position. This further reduces the defect of belt deviation.

[0055] At the same time, the above method can achieve the lifting in a very labor-saving way during the work process, and this method is easy to operate and the lifting height can meet the construction needs, thus greatly improving the working efficiency of the equipment.

[0056] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
