Detailed Description
The utility model discloses a sample holder cache track, which can save space as much as possible under the condition of additionally arranging a track and save cost as much as possible,
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, the terms "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The utility model discloses a tensioning device for a conveying track, which comprises a tensioning frame 2 and a tensioning adjusting wheel 1. The tensioning frame 2 is arranged below the conveyor belt and is fixedly connected to the bottom of the frame body. The conveyor belt is wound around a tension adjusting wheel 1. The tensioning adjusting wheel 1 is movably connected with the tensioning frame 2.
In the case that there is not enough installation space at the end of the conveyor belt, the present invention breaks the limitation of the installation space, arranges the tension frame 2 below the conveyor belt, and fixedly attaches the tension frame 2 to the bottom of the frame body. Tensioning regulating wheel 1 is movably connected on tensioning frame 2, and tensioning regulating wheel 1 provides the tensile force for the conveyer belt.
In the present invention, the tension adjusting wheel 1 is tightened on the conveyor belt by the elastic member, and the preset tension force of the elastic member is equal to the preset tension force of the tension adjusting wheel 1. If the tension adjusting wheel 1 moves upward, the tension of the belt becomes small, and the reaction force of the tension is the pushing force of the belt to the tension adjusting wheel 1. The tension of the spring assembly increases due to the upward movement of the tensioning adjustment wheel 1. Because the pulling force is greater than the pushing force, the tensioning adjusting wheel 1 moves downwards under the action of the pulling force until the pushing force is equal to the pulling force. When the pushing force is equal to the pulling force, the tensioning adjusting wheel 1 is just positioned at the preset position, and the elastic component is just in the preset stretching state. The elastic assembly is arranged to enable the tensioning adjusting wheel 1 to be always at a preset position, and the tensioning force of the tensioning adjusting wheel 1 is always a preset tensioning force. Therefore, the stability of the tensioning operation of the tensioning adjusting wheel 1 is improved.
The elastic assembly comprises in particular a spring 3 and a swing arm 4. The bottom of swing arm 4 articulates on tensioning frame 2, and the wheel hub connection of tensioning regulating wheel 1 is in the middle part of swing arm 4, and the upper end of spring 3 is connected on the upper portion of swing arm 4, and the lower extreme is connected on tensioning frame 2. If the tensioning adjustment wheel 1 is moved upwards, the swing arm 4 will rotate in the direction of the tension spring 3. As long as the swing arm 4 is rotated, the spring 3 is elongated and the tension increases. After the tensioning adjusting wheel 1 moves upwards, the pushing force of the conveyor belt to the tensioning adjusting wheel 1 is reduced. Because the tension adjusting wheel 1 is subjected to a downward pulling force which is larger than an upward pushing force, the tension adjusting wheel 1 moves downwards along with the rotation of the swing arm 4.
The tension frame 2 is connected with a sliding plate 9, and the lower part of the spring 3 is connected with the sliding plate 9. The slide 9 can be slid upwards relative to the tensioning frame 2 and can be locked on the tensioning frame 2 by means of locking elements. When the spring 3 is attached, the upper end of the spring 3 is connected to the swing arm 4, and the lower end of the spring 3 is connected to the slide plate 9. The slide plate 9 is initially in the uppermost position to keep the spring 3 in a natural state. After the spring 3 is installed, the hand-held sliding plate 9 gradually moves downwards until the spring 3 is in a preset tension state. The slide 9 is then locked to the tensioning frame 2 by means of the locking element. Compared with the mode of directly stretching the spring 3 to the preset tension state and then connecting the spring 3, the connecting of the spring 3 is completed in advance, and then the spring 3 is stretched through the sliding plate 9, so that the difficulty in mounting the spring 3 can be obviously reduced.
The principle of up-and-down adjustment of the slide plate 9 is as follows: the slide plate 9 is provided with an adjustment hole 7, and the adjustment hole 7 is a long hole extending in the vertical direction. The fixing screw 8 is fitted into the adjusting hole 7 and then locked to the tension frame 2. The range of the slide plate 9 sliding up and down is the length of the adjusting hole 7, that is, the slide plate 9 can slide up and down within the range of the length of the adjusting hole 7. In order to improve the firmness of the connection of the sliding plate 9 and the tensioning frame 2, the number of the adjusting holes 7 is limited to two, and the two adjusting holes 7 are arranged side by side.
In order to ensure stable up-and-down movement of the slide 9, the present invention provides a guide groove on the tension frame 2, which extends in the up-and-down direction. The slide plate 9 fits in the guide groove. The width dimension of the guide groove is slightly larger than that of the slide plate 9, so that the guide groove can limit the slide plate 9 in the width direction to ensure stable up and down movement of the slide plate 9.
Regarding the specific connection manner of the spring 3: the upper part of the swing arm 4 is provided with a swing arm connecting post 5, and the sliding plate 9 is provided with a sliding plate connecting post 6. The swing arm connecting column 5 and the sliding plate connecting column 6 are both provided with a reducing part, and the upper end and the lower end of the spring 3 are respectively hooked on the reducing part of the swing arm connecting column 5 and the reducing part of the sliding plate connecting column 6.
In order to improve the tensioning effect of the tensioning adjusting wheel 1, the tensioning driven wheel 10 is further arranged. The tensioning driven wheels 10 are rotatably arranged on the tensioning frame 2, the number of the tensioning driven wheels 10 is two, the two tensioning driven wheels 10 are respectively arranged on two sides of the tensioning adjusting wheel 1, and the two tensioning driven wheels 10 are positioned above the tensioning adjusting wheel 1.
Regarding the fixing manner of the tension frame 2: the utility model is provided with a lug at the side of the upper part of the tension frame 2, and the lug is provided with a bolt hole for connecting with a positive side beam or a reverse side beam. I.e., the tension frame 2 is fastened to the bottom of the forward side member or the reverse side member.
