And a shifting fork m0 capable of driving the suspension chain h1 to move is mounted on a driving chain of the driving mechanism m. The driving mechanism m is a motor driving a driving chain to circularly run between the upper part and the lower part, and is mainly characterized in that a shifting fork m0 is designed, and a shifting fork m0 is positioned on the peripheral edge of a driving chain circulating path and extends outwards, so that the shifting fork m0 can contact with a suspension chain h1, a link shaft on a chain link of the suspension chain h1 can be hung, and the suspension chain can be driven to move forwards. And the hanging chain h1 can be a double guide wheel chain which can be well pushed by the shift fork m 0. Of course, since fork m0 is required to drive suspension chain h1, the top of the rail segment in the portion of the rail segment in the drive mechanism is open, so that suspension chain h1 in the rail segment can contact fork m 0.

In addition, the guide rail assembly h comprises a plurality of guide rail sections 1, and the guide rail sections 1 are provided with a conveying channel 10 for the suspension chain h1 to pass through and have a cross-shaped section.

The guide rail tensioning mechanism mentioned above, which will be described in further detail below, is used in the system of the present application, and has a better effect for tensioning a suspension chain, in the present embodiment, the tensioning mechanism to be described is implemented by means of a part of segments in a guide rail assembly, so that the guide rail in the present embodiment is not only used for guiding the suspension chain, but also can be used for tensioning the suspension chain by means of a new structural design on the corresponding guide rail segments, and the guide rail assembly is assembled by a plurality of guide rail segments 1, the guide rail segments 1 are shaped as straight segments and arc segments, and have horizontal segments, climbing/descending segments in the direction, the guide rail assembly is a complete conveyor line formed by connecting a plurality of guide rail segments 1 in a butt joint manner, and the guide rail tensioning mechanism of the present application can be arranged on one or a plurality of segments, the specific scheme is as follows:

the device comprises at least one group of first guide rail section a and second guide rail section b which are arranged adjacently on a guide rail assembly conveying path and are internally provided with conveying channels 10 for a suspension chain to pass through, and a guide rail section distance adjusting device which can prolong the spacing distance between the conveying channel butt joints 101 of the first guide rail section a and the second guide rail section b which are adjacent to each other on the guide rail assembly conveying path and prolong the guide rail assembly conveying path.

In the above solution, the first guide rail section a and the second guide rail section b are two continuous sections of the guide rail assembly, and the conveying channel 10 is actually a guide groove for guiding the suspension chain, the mechanism of the present application needs to be realized only by the guide rail mechanism of the conveying channel 10, because the wall surface of the conveying channel 10 is used to apply force to tension the suspension chain, and the conveying channel 10 needs to penetrate through the whole guide rail section 1, the conveying channel 10 on one guide rail section 1 has two conveying channel interfaces 101 at the head and the tail, and is respectively paired with the conveying channel interfaces 101 of the other guide rail section 1 for the suspension chain to pass through in sequence, in addition, it needs to be noted here that the length of the conveying path of the guide rail assembly is not only the sum of the lengths of the conveying channels 10 on the respective guide rail sections 1, most of the adjacent guide rail sections 1 are spliced, and the adjacent conveying channel interfaces 101 between the two are also tightly attached, the spacing distance is basically kept at 0, but there are also some parts with spacing distance between adjacent guide rail sections 1 larger than 0, even more than tens of centimeters, because the whole guide rail assembly is spaced apart a little according to the needs of the field, if not necessary, the guide rail sections 1 should be spliced closely as much as possible, so that not all guide rail sections 1 are spliced closely, some are spaced apart by a certain distance, and the spacing place is used for the suspension chain to pass through and is in a suspended state, the place can be called as a suspended section, the suspended section is also required to be recorded in the length of the conveying path of the guide rail assembly, because the suspension chain passes through, the conveying path of the guide rail assembly is a section including the guide rail sections 1 and the suspended section for the suspension chain to pass through, and the total length of the conveying path is required to be counted, in the existing equipment, the original guide rail conveying path is basically maintained unchanged under the condition that the original guide rail conveying path is not changed, so the equipment is used for a long time, when the suspension chain is loosened, the length of the suspension chain cannot be well matched with the guide rail conveying path, the problems of unsmooth operation, blocking, chain dropping and the like can be caused because the suspension chain is lengthened and the guide rail conveying path is unchanged, of course, a plurality of special tensioning mechanisms are also arranged in the prior art, but the scheme of the application is realized by a mode of prolonging the guide rail conveying path, so the guide rail is used for tensioning the suspension chain, and the guide rail section distance adjusting device can be arranged to prolong the spacing distance between the conveying channel butt-joint ports 101 which are adjacent to each other and are arranged between the first guide rail section a and the second guide rail section b, namely, a suspended section can be generated between the first guide rail section a and the second guide rail section b, and this unsettled section has the ability of extension, then, among this application straining device, first guide rail section an and second guide rail section b and between the two these three sections route sums of this unsettled section are can prolonging, have this basis, this application straining device just can make the guide rail assembly also can have the potentiality of prolonging whole transfer route, the extension of guide rail assembly transfer route, just can carry out better tensioning to the suspension chain that becomes loose. Since the guide rail section distance adjusting device in this embodiment needs to be disposed in the area between and around the first guide rail section a and the second guide rail section b, initially, the first guide rail section a and the second guide rail section b need to ensure a sufficient distance therebetween, that is, a suspended section needs to be reserved first for installation of the guide rail section distance adjusting device, which will be described in detail later.

In fact, the function of the guide rail section distance adjusting device is a force application process of pushing the first guide rail section a and the second guide rail section b away, so in the actual operation process, the guide rail assembly is required to be matched with the guide rail assembly to achieve the extension of the conveying path of the guide rail assembly, because in the tensioning mechanism of the present application, the first guide rail section a and the second guide rail section b need to exert force with other guide rail sections 1 of the guide rail assembly to convert the extension of the conveying path of the tensioning mechanism into the extension of the conveying path of the guide rail assembly, because if two ends of the whole tensioning mechanism cannot exert force to push the guide rail section 1 butted with the two ends even in the extension process of the conveying path of the whole tensioning mechanism, the conveying path of the tensioning mechanism cannot be converted into the extension of the conveying path of the guide rail assembly, and thus the tensioning effect cannot be achieved, and the two deviated ends of the first guide rail section a and the second guide rail section b respectively need to be matched with the conveying path of the guide rail assembly when the installation is finished Two sections in the diameter are butted and abutted with the guide rail section 1 as tightly as possible; or at least the conveying path of the tensioning mechanism is extended when the tensioning mechanism tensions the suspension chain, the two deviated ends of the first guide rail section a and the second guide rail section b can also exert force to push the butted guide rail sections 1 which respectively correspond to the other parts of the conveying path of the guide rail assembly. It can thus be ascertained that the guide track section 1 of the guide track assembly transport path, which is not part of the tensioning means, of the guide track sections 1 abutting against the ends of the first guide track section a and the second guide track section b, which are offset from each other, at least one side of the guide track section 1 is required to have a displacement capability, and the first guide track section a or the second guide track section b abutting against this side is also required to have a displacement capability, wherein the displacement capability means that during adjustment of the tensioning means the guide track sections can be pushed apart by a distance after applying a pushing-apart force to the adjacent ends of the first guide track section a and the second guide track section b during adjustment of the guide track section spacing adjustment means, so that a movement is required which can be pushed apart and displaced by a certain distance during adjustment of the guide track section spacing adjustment means, rather than being in a fixed state, without any means being able to effect a displacement of the tensioning means between the abutment 101 of the transport path between the first guide track section a and the second guide track section b The spacing distance is extended and translated to the entire track assembly transport path, as will be described in more detail below. Of course, all the above mentioned sections of the track assembly should be in a static state where the position is kept unchanged in the normal transportation state, and the movement is also realized by applying force through the track section distance adjusting device in the tensioning process.

The guide rail section distance adjusting device can adopt the existing telescopic connection structure such as a screw rod, an air cylinder and the like and is clamped in the area between the first guide rail section a and the second guide rail section b. The embodiment provides a scheme with excellent effects in all aspects:

namely, the guide rail distance adjusting device comprises a first suspension plate c and a second suspension plate d which are respectively sleeved on the peripheries of the first guide rail section a and the second guide rail section b and are respectively used for suspending the first guide rail section a and the second guide rail section b, and a screw rod 2 which is arranged on the first suspension plate c and the second suspension plate d in a penetrating way and extends along the conveying path direction between the conveying channel butt joints 101 of the first guide rail section a and the second guide rail section b, wherein the screw rod 2 is respectively provided with an adjusting nut 3 at the front side and the rear side of the first suspension plate c and at the front side and the rear side of the second suspension plate d, the guide rail distance adjusting device further comprises a tension spring 4, two ends of which are respectively at least partially abutted against the end surface of the conveying channel butt joint 101 of the first guide rail section a and at least partially abutted against the end surface of the conveying channel butt joint 101 of the second guide rail section b, and two ends of the tension spring 4 are respectively at least partially abutted against the first suspension plate c and at least partially abutted against the end surface of the first suspension plate c Respectively against said second suspension plate d. In a suspension chain system, each guide rail section 1 needs to be hung by a suspension plate 11, so that a guide rail assembly is in a suspension state, the upper part of the suspension plate 11 is usually connected by the installation of the existing top support mechanisms such as a suspension chain or a suspension, and the suspension plate 11 can be hung, and the guide rail section 1 passes through the suspension plate 11 and is hung on the suspension plate 11.

In particular, in this embodiment, it is recommended that the first guide rail section a and the second guide rail section b are both straight guide rail sections, and it is preferable that the combination of the first guide rail section a and the second guide rail section b is a work which is provided at a position of the guide rail section 1a which turns 180 degrees in the guide rail assembly and can be tensioned at the position, the first guide rail section a may be provided as a section which directly or indirectly abuts on one end of the guide rail section 1a, and the second guide rail section b may be provided as a section which abuts on the guide rail section 1 in the drive mechanism area;

preferably, one of the first guide rail section a and the second guide rail section b is a fixed section, and the other is a movable section, and the first guide rail section a can be selected as a movable section, and the second guide rail section b can be selected as a fixed section, which is advantageous in that there are fewer sections near the guide rail section 1a that are engaged with the first guide rail section a, and there are fewer structures involved in the movement, which is convenient for control and design The direct butt joint means that the two are directly spliced, the indirect butt joint means that a plurality of linear guide rail sections 1 of different sections can be clamped between the two, when the guide rail section 1a and the guide rail section 1a are tensioned, the first guide rail section a and the guide rail section 1a or the guide rail section 1 between the two are required to be movably expanded outwards together to tension a chain, the second guide rail section b is used as a fixed section, the part of the second guide rail section b, which is butted against the far end of the first guide rail section a, is also the guide rail section 1 which cannot be moved, so that the second guide rail section b cannot be pushed away, the plurality of guide rail sections 1 which are partially butted against each other can be fixed on a driving mechanism or a beam column in a workshop and the like, the suspension plates 11 on the guide rail sections 1 of the part can not be installed and connected through a top supporting mechanism, but the suspension plates 11 are arranged as far as possible, since such a suspension chain system will normally be equipped with a conveyor device below the guide rail mounted on the suspension plate 11. The first suspension plate c and the second suspension plate d mentioned in the present application are certainly two of all the suspension plates 11, but there is a requirement for the positions of the two plates, and they are actually respectively arranged at the end face positions of the adjacent ends of the first guide rail section a and the second guide rail section b, so that one of the two ends of the tension spring 4 can simultaneously abut against the end face of the first guide rail section a and the plate face of the first suspension plate c, and the other end can simultaneously abut against the end face of the second guide rail section b and the plate face of the second suspension plate d, so that the tension operation can be well performed, and because the first suspension plate c and the second suspension plate d are provided with the screw 2 and the adjusting nut 3, the distance between the first suspension plate c and the second suspension plate d is locked by the adjustment of the adjusting nut 3, even though there is the tension spring 4, the first suspension plate c and the second suspension plate d are not pushed away by the tensioning spring 4, so that the tensioning operation can be controlled, that is, the adjusting nuts 3 are unscrewed outwards in a direction away from the first suspension plate c or away from the second suspension plate d, so that a degree of freedom can be provided, the tensioning spring 4 is enabled to prop open the first suspension plate c and the second suspension plate d and the first guide rail section a and the second guide rail section b, and the tensioning spring 4 pushes open the first suspension plate c and the first guide rail section a and drives the guide rail section 1a to expand outwards due to the fixed part of the second suspension plate d and the second guide rail section b, so that the interval between the first guide rail section a and the second guide rail section b is prolonged, the first suspension plate c and the second suspension plate d can be well converted to the conveying path of the guide rail assembly, the conveying path of the guide rail assembly is prolonged, and the whole integrated suspension chain can be tensioned on the guide rail, the tensioning degree is determined by the adjusting travel of the adjusting nut 3 towards the direction away from the first suspension plate c and the second suspension plate d, and of course, after tensioning, due to the existence of the adjusting nut 3, the tensioning degree can be limited to the position of the adjusting nut 3, and can not be infinitely tensioned, and if tensioning is needed subsequently, the position of the adjusting nut 3 is adjusted. Then, based on the fact that the guide rail section 1a is a U-shaped structural section, it is preferable to arrange a set of first guide rail section a and second guide rail section b at two ends of the guide rail section 1a to extend the conveying path of the guide rail assembly, that is, in this embodiment, two sets of first guide rail section a and second guide rail section b are preferably symmetrically arranged, two sets of two guide rail section spacing adjusting devices are provided, and by adjusting the two guide rail section spacing adjusting devices, the two tensioning springs 4 at two positions applying force to two ends of the guide rail section 1a can respectively push the first guide rail section a in the two sets and extend outwards against the guide rail section 1a, the force applied to two ends can make the tensioning process more stable, the force effect is better, and the adjustment is preferably performed at two positions simultaneously, a better tensioning effect can be achieved.

For better tensioning, the first suspension plate c and the second suspension plate d may be further provided with a directional rod 5 extending along the direction of the conveying path between the conveying channel butt-joint ports 101 of the first guide rail section a and the second guide rail section b, the directional rod 5 is preferably of a linear type, so as to ensure linear tensioning push-away expansion between the first guide rail section a and the second guide rail section b, and better transmit to the butt-joint end of the steering guide rail section 1a, because the tangential directions of the two ends of the steering guide rail section 1a are two parallel linear extending directions, and the two sets of the first guide rail section a and the second guide rail section b perform linear push-away operation right at the two ends of the steering guide rail section 1a during tensioning, so that the first guide rail section a is outwards expanded together with the steering guide rail section 1a to extend the conveying path of the guide rail assembly in a linear manner And effectively tensions the chain.

In a further design, the cross section of the conveying channel 10 is in a cross shape, wherein the cross section refers to the shape of the cross section of the conveying channel 10 in the advancing direction of the chain, and the shape of the matched suspension chain can adopt a double-guide-wheel chain;

each set of the first guide rail section a and the second guide rail section b may be provided with at least one guide rod 5 for passing through the tension spring 4, four guide rods 5 may be selected and respectively disposed in four corner regions of the crossing position of the conveying paths 10 of the first guide rail section a and the second guide rail section b, and the guide rail section pitch adjusting device may be provided with two tension springs 4 respectively disposed in the regions of the lower left corner and the lower right corner of the first guide rail section a, and the two tension springs 4 are just provided for one guide rod 5 to pass through.

Above-mentioned design can lead to the tensioning operation better to make the tensioning process more reliable and more stable.

Such suspension chain conveyor systems are generally equipped with a conveyor car which travels with the chain in the area below the guide rail, so that the tensioning mechanism of the present application is further optimized as follows: a first guide rod section e and a second guide rod section f which are consistent with respective conveying paths are respectively arranged at positions right below the first guide rail section a and the second guide rail section b, a lower tensioning spring 44 is arranged between the first guide rod section e and the second guide rod section f in an abutting mode, the first guide rod section e is installed on a first suspension plate c through a first cantilever arm 81, and the second guide rod section f is installed on a second suspension plate d through a second cantilever arm 82. The guide rod assembly is used for the conveying vehicle to travel, the first guide rod section e and the second guide rod section f are respectively the subsections of the guide rod assembly, the guide rod assembly is also composed of all the guide rod sections, the general structural form is consistent with that of the guide rail assembly, only the guide rod assembly is used for the conveying vehicle to travel and is combined by the sections which are all round rod-shaped, the structure is such that, during the process of adjusting and tensioning the upper first guide rod section e and the second guide rod section f through the adjusting nut 3, the lower tensioning spring 44 also pushes the first guide rod section e and the second guide rod section f apart due to its own spring force, the active state of the section of the guide rod assembly is consistent with the active state of the guide rail assembly, and the conveying path of the guide rod assembly is consistent with the conveying path of the guide rail assembly, so that the stable state of the conveying vehicle along with the suspension chain can be ensured.

In addition, the first guide rod section e and the second guide rod section f can both adopt hollow tubes, a guide embedded rod g is arranged between the first guide rod section e and the second guide rod section f, and two ends of the guide embedded rod g are respectively sleeved in the first guide rod section e and the second guide rod section f, and the lower tensioning spring 4 is sleeved on the guide embedded rod g, so that the lower tensioning spring 4 can effectively generate driving force to the first guide rod section e and the second guide rod section f in a linear mode;
