Detailed Description

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 given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention.

In a specific embodiment provided by the invention, the belt conveyor frame connecting structure mainly comprises a connecting underframe 1, a longitudinal beam 2, a sleeve 3 and a joint 4.

The connecting underframe 1 is positioned between the longitudinal beams 2 to be connected at two ends, the sleeve 3 is arranged on the connecting underframe 1, the joint 4 is arranged on the end part, right opposite to the longitudinal beams 2 at two ends, of the connecting underframe and right opposite to the sleeve 3, and the connecting underframe is mainly used for being connected with the sleeve 3 in a matching mode.

Importantly, seted up joint hole 31 on the lateral wall of sleeve pipe 3, be provided with joint post 41 on the lateral wall that connects 4, and this joint post 41 can carry out concertina movement on the lateral wall that connects 4 to when the outer end of joint post 41 stretches out to the lateral wall that connects 4 outside, form the joint cooperation with joint hole 31 on the sleeve pipe 3 lateral wall.

So, the belt feeder frame connection structure that this embodiment provided, when needs connect both ends longeron 2, only need all insert joint 4 on the longeron 2 of both ends and establish the sleeve pipe 3 on connecting chassis 1 for joint post 41 on the 4 lateral walls that connect stretches out to form the joint locking with the joint hole 31 on the 3 lateral walls of sleeve pipe, can form the butt joint through connecting chassis 1 with both ends longeron 2. Compared with the connection of fasteners such as bolts in the prior art, the connection matching mode of the connector 4 and the sleeve 3 and the clamping locking mode of the clamping column 41 and the clamping hole 31 are simpler and easier, so that the splicing of the belt conveyor frame can be simply and conveniently realized, and the connection stability is improved.

In a preferred embodiment with respect to the sleeve 3 and the joint 4, in order to improve the stability of the connection of the sleeve 3 to the connecting underframe 1 and the stability of the connection of the joint 4 to the longitudinal beam 2, the outer wall of the sleeve 3 is welded in particular to the top of the connecting underframe 1, and likewise the inner end of the joint 4 is welded in particular to the end of the longitudinal beam 2. Of course, the connection between the sleeve 3 and the connecting underframe 1 and the connection between the joint 4 and the longitudinal beam 2 can be pre-installed before the butt joint, so that the installation at the operation site does not cause safety risks. Furthermore, the connection between the sleeve 3 and the connecting underframe 1 and the connection between the joint 4 and the longitudinal beam 2 are not limited to welding, but other connections, such as connection by connecting elements, connection by fasteners, connection by connecting structures, etc., may be used as well.

In order to facilitate the smooth insertion of the joints 4 on the longitudinal beams 2 at the two ends into the sleeves 3 to form the clamping locking, in this embodiment, the specific distribution positions of the sleeves 3 on the connecting underframe 1 are coaxially distributed with the specific distribution positions of the joints 4 on the longitudinal beams 2. So set up, when carrying out the butt joint, only need with both ends longeron 2 along the axial syntropy inwards linear motion can. Typically, the outer diameter of the nipple 4 is slightly smaller than the inner diameter of the casing 3.

In addition, considering that the end faces of the longitudinal beams 2 at the two ends are provided with the connectors 4, and the connection positions of the partial longitudinal beams 2 have specific requirements, for this purpose, the embodiment is provided with a circle of guiding chamfers 42 at the outer end edges of the respective connectors 4 along the circumferential direction, so as to indicate the correct plugging direction corresponding to the current connector 4 through the guiding chamfers 42, and prevent the connection positions of the longitudinal beams 2 at the two ends from being mixed.

In order to facilitate the telescopic movement of the clamping column 41 on the side wall of the joint 4, the through hole 43 is formed on the side wall of the joint 4 in the embodiment, and meanwhile, the clamping column 41 is specifically telescopically arranged in the through hole 43. So set up, when joint post 41 stretches out outside the via hole 43, can form the joint locking with the joint hole 31 of seting up on the sleeve pipe 3 lateral wall, and when joint post 41 withdrawed to in the via hole 43, can break away from the joint locking with joint hole 31.

Further, in order to facilitate the telescopic movement of the snap-in post 41 in the through hole 43, a slide hole 44 is provided in the joint 4 in the present embodiment. Specifically, the opening position of the slide hole 44 is located inside the joint 4, the through hole 43 is located on the side wall of the joint 4, the slide hole 44 communicates with the through hole 43, and the cross-sectional area of the slide hole 44 is larger than that of the through hole 43.

Accordingly, the clip column 41 specifically includes a cover 411 and an extension rod 412. Wherein the cover 411 is disposed in the slide hole 44 and is slidable in the slide hole 44 in the axial direction thereof. An extension rod 412 is connected to the outer end surface of the cover plate 411, and is mainly used for sliding in cooperation with the via hole 43. With such an arrangement, since the sliding sectional area is larger than the sectional area of the through hole 43, when the cover plate 411 slides to the end face of the sliding hole 44, it stops, and the extension rod 412 extends out of the through hole 43; when the cover 411 slides to the middle area of the slide hole 44, the extension rod 412 is pulled inward and retracted into the through hole 43.

In general, 2 or more snap-in posts 41 may be provided on the side wall of the joint 4 at the same time in the circumferential direction. Taking the example that the number of the clamping columns 41 is 2, the two clamping columns 41 can be arranged on the side wall of the joint 4 in a radial direction and oppositely distributed, the expansion direction of the clamping columns is generally perpendicular to the axial direction of the joint 4, the slide holes 44 and the through holes 43 are distributed in a corresponding radial direction, and the cover plates 411 of the two clamping columns 41 can share the same slide hole 44.

Further, in order to realize the automatic extension and retraction of the clamping column 41 on the side wall of the joint 4, a spring 45 is additionally arranged in the embodiment. Specifically, the springs 45 are disposed in the slide hole 44 and distributed along the length direction of the slide hole 44, and the inner end surface of the cover 411 is connected to the end of the spring 45. Before the spring 45 is installed in the slide hole 44, the spring 45 has a certain pre-compression amount, so that after the spring 45 is installed in the slide hole 44, the cover plates 411 at both ends are respectively abutted to the end surfaces of the slide hole 44 by the elastic force of the spring 45, and the outer ends of the extension rods 412 are kept extending out of the through holes 43.

Furthermore, considering that when the connector 4 is inserted into the casing 3, the outer end of the extension rod 412 already extends out of the through hole 43, and therefore interference can be generated during insertion, at this time, the extension rod 412 generally needs to be manually pressed to be pressed into the through hole 43. Specifically, the wedge face 413 faces the plug-in direction and can be first brought into contact with the outer wall of the sleeve 3 during plug-in, so that the extension rod 412 is pressed into the through hole 43 by utilizing the oblique component force of the axial contact acting force on the wedge face 413, thereby realizing automatic pressing and avoiding interference.

Further, considering that the wedge surface 413 on the extension rod 412 needs to keep facing the plugging direction, so as to form an abutting acting force with the outer wall of the sleeve 3 when being installed, in order to avoid the deviation of the facing direction of the wedge surface 413 on the extension rod 412, the extension rod 412 needs to limit the circumferential rotation freedom degree in the through hole 43, and meanwhile, the axial movement freedom degree is ensured. In this regard, in the present embodiment, the cross-sectional shapes of the extension rod 412 and the via hole 43 are both non-circular, for example, the cross-sectional shapes of the extension rod 412 and the via hole 43 are both rectangular, trapezoidal, and key-shaped. With this arrangement, the extension rod 412 cannot rotate in the through hole 43, so as to ensure that the orientation of the wedge surface 413 is always unchanged. Of course, the cross-sectional shapes of the cover 411 and the slide hole 44 may be non-circular or circular.

In addition, in order to facilitate the operations of taking, placing, and dismounting the snap-in post 41 and the spring 45 in the sliding hole 44, a dismounting groove 46 is further formed on the side wall of the joint 4 in the embodiment. Specifically, the mounting/dismounting groove 46 is formed in a region of the side wall of the joint 4 corresponding to the slide hole 44, and the slide hole 44 can be directly exposed after the mounting/dismounting groove 46 is formed, so that the snap-in post 41 and the spring 45 can be mounted in the slide hole 44 from the mounting/dismounting groove 46. Generally, since the spring 45 has a pre-compression amount, it can be extended after being placed in the sliding hole 44, so that the length of the spring 45 is greater than that of the mounting slot 46, thereby preventing the spring 45 from falling out of the mounting slot 46. Of course, a flip cover or the like may be added to the notch of the detachable groove 46 for closing.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
