Description
Technical Field
The invention relates to the field of material product conveying and transporting, in particular to an adjustable positioning supporting mechanism of a chain machine and the chain machine comprising the mechanism.
Background
The chain conveyor is conveying equipment which carries unit cargoes and runs horizontally continuously, has the advantages of strong flexibility in conveying cargoes, light weight, low price and the like, and is one of the most used equipment in the current automatic logistics equipment. However, in the practical use process, due to different use environments, the characteristics of the carried and transported products are different, and the chain conveyor not only needs to consider the problems of stable carrying and conveying and transferring efficiency of cargoes, but also needs to consider the problems of impact, vibration and deformation possibly generated on different connection positions and different structural parts in the long-time working process. If the design of a solution to such problems is neglected, the problem often results in that the conveying production line cannot be rapidly solved when abnormal conditions occur, and the conveying production line is stopped for a long time, so that great economic losses are caused for enterprises.
The double-row middle-drive chain machine with the unpowered roller way disclosed in the Chinese patent application publication No. CN202022755660.4 comprises a drive mounting bracket, a front end mounting bracket, two conveying parts, a driving mechanism arranged on the drive mounting bracket and used for driving the two conveying parts, a protection plate arranged on the conveying parts and close to one end of the front end mounting bracket, and the unpowered roller way arranged between the two conveying parts.
Another example is a novel chain machine transition steering wheel device disclosed in the chinese patent application document with the application number CN202122752978.1, which comprises a first chain machine and a second chain machine, wherein two chains of the second chain machine are vertically connected with one chain of the first chain machine, two vertical joints form two confluence corners, the two confluence corners are respectively positioned at two sides of the second chain machine, a first chain machine rail and a second chain machine rail at the confluence corners comprise first rails, each first rail comprises a first flat plate and two parallel second flat plates, the first flat plate and the two second flat plates form a groove, and the opening of the groove faces the corresponding chain machine; and a mounting shaft is arranged between the two second plates, steering wheels are sleeved outside the mounting shafts, the steering wheels of the adjacent mounting shafts are not at the same height, and the steering wheels of the two mounting shafts of which the middle is spaced by the mounting shaft are at the same height.
By analyzing and comparing the technical schemes given in the two patent application documents, it can be found that, for different chain machines, a plurality of supporting feet are often required to be fixedly installed at the bottom of a mounting bracket for arranging a conveying belt, and the supporting feet are used for lifting the conveying belt to a certain height position as required so as to meet different actual conveying work demands. In the practical application process, the inlet and outlet positions of the materials of the conveyed materials are changed along with the characteristics of different production lines and different materials, so that vibration impact generated when the materials enter the conveying line can be born at different positions of the mounting bracket on a strip-shaped integral conveying line, and more supporting legs or reinforcing supporting devices are required to be arranged at the positions. Most chain machines generally directly adopt a structure in which the supporting legs are fastened and fixed on the mounting bracket by bolts at positions where positioning mounting holes are provided in advance, and the positions of the supporting legs cannot be adaptively adjusted according to actual conveying scenes or changes of conveyed products, which cannot cope with the above situations. Although a small number of chain machines also consider the need to change the position of the supporting leg during practical application, the supporting leg still adopts a form of forming a plurality of mounting holes on the mounting bracket, so that the supporting leg needs to be detached from the mounting bracket for reinstallation when the supporting leg is adjusted. In such an adjustment mode, the relative position of the supporting leg is inevitably required to be checked again in the installation process, so that the whole process becomes more complicated, and in addition, in the use environment where embedded chain machines or external device components exist for shielding, the supporting leg is inconvenient or even impossible to detach or install.

Detailed Description
The following specific examples are intended to be illustrative of the invention and are not intended to be limiting, as modifications of the invention will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.
The scheme is realized by the following technical means:
examples: in this embodiment, a novel chain machine apparatus is provided, which can control and adjust the position of the supporting leg 3 between the connection mounting frame 2 and the ground rapidly and efficiently according to the change of the practical application environment or the difference of the characteristics of the transported materials while ensuring the reliability of the supporting and the stability of the transportation.
For the chain machine equipment provided by the scheme, an adjustable positioning supporting mechanism of the chain machine is formed on two sides of the chain machine equipment, and the chain machine equipment is similar to a common chain machine, and comprises a connecting installation frame 2, and a conveying belt 1 and supporting legs 3 are respectively arranged on the upper side and the lower side of the connecting installation frame 2. The whole connecting mounting frame 2 is in a slender and straight rod state, and the connecting mounting frame 2 is hollow and has openings at two ends. The roller mechanisms are respectively arranged at the two ends of the upper part of the connecting mounting frame 2, and the annular conveying belt 1 is simultaneously arranged on the rollers of the roller mechanisms at the two ends in a surrounding mode, so that the conveying belt 1 drives a material part placed on the upper surface of the conveying belt 1 or a plate for bearing the material part to move horizontally from one end of the chain machine to the other end of the chain machine. Of course, the conveyor belt 1 here may be a belt made of an elastic rubber material, or a metal chain belt formed by hinging a plurality of metal links to each other. The conveyor belt 1 is arranged on the connecting mounting frame 2 in the adjustable positioning supporting mechanisms at the two sides in the mode, a driving device 4 is fixedly arranged between the adjustable positioning supporting mechanisms at the two sides, and the conveyor belt 1 can be driven to continuously perform rotary motion by using a driving motor through a series of gear tooth transmission mechanisms in a transmission fit connection mode.
In the scheme, the chain transportation transmission structure part is not an important point of optimization and improvement, so that the structure part is simply described on the working principle and is not unfolded.
In contrast, the technical solution presented as an optimization and improvement in this embodiment is focused on the connection structure between the connection mounting frame 2 and the supporting leg 3. The chain machine adjustable positioning supporting mechanism comprises a supporting unit A for realizing the supporting effect of the supporting legs 3 on the connecting mounting frame 2 in the vertical direction and a positioning locking unit B for realizing the locking fixation of the supporting legs 3 at different positions along the extending direction of the connecting mounting frame 2; in terms of position, the support bearing unit a and the positioning locking unit B are arranged between the support foot 3 and the connection mounting frame 2.
The supporting unit a includes a supporting bottom formed on the lower side of the connection mount 2 and a supporting top formed on the upper side of the supporting leg 3, and the supporting leg 3 has a supporting effect on the connection mount 2 in the vertical direction by the abutting action of the supporting top and the supporting bottom. And in the location locking unit B, the location locking unit B includes a limit matching portion formed on the connection mounting frame 2 and a limit clamping portion formed on the supporting leg 3, and by the mutual abutting action between the limit clamping portion and the limit matching portion, the locking and fixing effect of the supporting leg 3 relative to the connection mounting frame 2 along the extending direction of the connection mounting frame 2 on a plane is achieved.
Specifically, for the supporting bearing unit a, a guiding installation groove 2a with the same trend as the whole extending direction of the connecting installation frame 2 is formed at the bottom of the connecting installation frame 2 which is in the shape of a slender hollow tube and has two through ends, at this time, the cross section of the connecting installation frame 2 is in a shape of an inverted U with a downward opening, and meanwhile, the hollow area inside the connecting installation frame 2 is also communicated to form a part of the guiding installation groove 2 a. When the connection mount 2 is placed on the support leg 3 placed upright in this state, the bottom surface of the connection mount 2 serving as the support bottom and the top surface of the support leg 3 serving as the support top are abutted against each other, thereby achieving the supporting effect on the upper member. For an elongated connection mount 2, the number of support feet 3 arranged on its underside and the actual installation position can be selected as a function of its actual length.
And for the positioning locking unit B, the friction effect generated after the limit matching part on the connecting mounting frame 2 and the limit clamping part arranged on the supporting leg 3 are mutually abutted is utilized, so that the supporting leg 3 is fixed at a specific required position relative to the connecting mounting frame 2 and does not move any more. The limit engaging portion is not integrally connected and fixed to the main body portion of the support leg 3, but is provided on a movable member located above the support leg 3, because it is necessary to control the support leg 3 to switch between the two states of movement and locking with respect to the connection mount 2.
Structurally, the positioning and locking unit B comprises at least a first limiting connection assembly 7 mounted on the supporting leg 3 and a part of the connection mounting frame 2. The first limiting component comprises a limiting connecting piece 7a which is arranged at the upper part of the supporting leg 3 in an adjustable and movable mode, and an adjusting connecting piece 7b which is used for changing the position state of the adjusting limiting connecting piece 7 a.
In particular, for example, a flat snap plate member can be selected as the limit connection member 7a, which is located in a hollow area inside the guide mounting groove 2a of the connection mounting, while the interval between the center connection points of the different positions on the outer peripheral surface of the snap plate member with respect to the through hole is varied. The adjusting connecting piece 7b is in a shape of a rod which is vertically arranged, the lower end part of the adjusting connecting piece is connected with a driving section with larger radial dimension, and a threaded structure or a concave-convex part is formed on the driving section so as to drive the adjusting connecting piece 7b and a clamping plate piece fixed on the adjusting connecting piece 7b to rotate together as a whole. The adjusting connector 7b is welded or adhered to the central connecting point of the clamping plate after passing through the main body of the supporting leg 3 from bottom to top. During connection and installation, the clamping plate serving as the limiting connecting piece 7a can be placed into the guide installation groove 2a in a state of small size in the horizontal left-right direction, at the moment, the clamping plate can be rotated to a state of large size in the horizontal plane left-right direction by rotating the lower driving section of the rod-shaped adjusting connecting piece 7b until the outer peripheral surface of the clamping plate is tightly abutted and fixed with the inner wall surface of the guide installation groove 2a, and at the moment, locking and fixing of the supporting leg 3 relative to the extending direction of the guide installation groove 2a are realized through friction force generated at the abutted part. When the position of the supporting leg 3 needs to be changed, the supporting leg 3 can be changed into a relaxed adjustable state by only reversely rotating the adjusting connecting piece 7b, so that the supporting leg 3 can be conveniently and quickly moved and adjusted.
In view of the above-mentioned stability of the supporting leg 3 in the supporting roof supporting unit a relative to the connection mounting frame 2, and in order to prevent the connection mounting frame 2 from being deformed by the excessive supporting roof force generated by the limiting engagement portion on the limiting connection piece 7a on the connection mounting frame 2 in the process of rotating the adjusting connection piece 7B to fix the supporting leg 3 in a locking manner, another more preferable structural form may be adopted for the positioning locking unit B.
Specifically, similar to the aforementioned connection mounting frame 2, a guiding mounting groove 2a is formed at the lower portion of the connection mounting frame 2 having a shape of a long and thin hollow rod, but further, two sides of the lower end portion of the guiding mounting groove 2a extend inwards to form an adduction connection section 201. The adduction connecting section 201 is connected with the end part of the connecting installation frame 2 which extends downwards, so that a supporting bottom with larger area is formed, and the bearing stability between the supporting feet 3 and the connecting installation frame 2 is improved. Further, a plate-like engaging plate member is selected to be placed in the guide mounting groove 2a, and when the engaging plate member is rotated to an arbitrary angular position, the width dimension thereof in the horizontal left-right direction is larger than the width of the opening portion of the guide mounting groove 2a, and a through hole extending in the vertical direction is formed in the center portion of the engaging plate member. And for the adjustment connecting member 7b, a pair of bolts and nuts corresponding to each other is selected. When the nut is installed, the nut is firstly required to be fixed on the upper surface of the clamping plate through the clamping groove matching structure so as to prevent the nut from rotating relative to the clamping plate. Of course, under the condition of allowable process conditions and cost, the screw thread can be directly arranged in the through hole of the clamping plate or the nut part can be integrally formed on the upper part of the clamping plate, so that the function of the nut structure and the clamping plate can be directly integrated.
After the matching and positioning of the nut and the clamping plate are completed, the bolts sequentially pass through the upper parts of the supporting legs 3 and the through holes of the clamping plate from bottom to top in an inverted state, and then are preliminarily screwed, connected and fixed with the nut. In this state, a gap area exists between the lower surface of the engaging plate member and the upper surface of the main body of the support leg 3, and when the height of the gap area is larger than the thickness of the aforementioned adduction connecting section 201, the engaging plate member as the limit connecting member 7a, the bolt and nut as the adjusting connecting member 7b, and the main body portion of the support leg 3 can slide inward from the one end opening portion of the connection mount 2 into any position of the connection mount 2. In this state, the adduction connecting section 201 is located exactly in the gap region between the lower surface of the click plate member and the upper surface of the main body of the support foot 3.
After the position adjustment of the supporting leg 3 in the extending direction relative to the connection mount 2 is completed, only the bolt serving as the adjustment connector 7b needs to be continuously rotated, so that the nut can be moved to the lower large end of the bolt, and the clamping and fixing effects on the clamping plate between the nut and the end of the bolt, the adduction connecting section 201 and the top of the supporting leg 3 main body are realized. In this structure, the lower surface of the engaging plate member and the upper surface of the supporting leg 3 simultaneously become a limiting engaging portion, and the upper and lower surfaces of the adduction connecting section 201 simultaneously become corresponding limiting engaging portions, so that the supporting leg 3 is fixedly connected to the connecting mounting frame 2 at a desired position in a manner of clamping the upper and lower sides of the adduction connecting section 201. Because the bottom surface of the clamping plate member and the top surface of the supporting leg 3 clamp the adduction connecting section 201 which is completely solid and is bent inwards, the connecting mounting frame 2 is not deformed and damaged even when a great clamping force is applied. In addition, when the supporting leg 3 is fixed relative to the connecting mounting frame 2 by adopting the structure, the surface processing is carried out on the upper side surface and the lower side surface of the connecting section 201 when the connecting section 201 on the connecting mounting frame 2 is formed by bending, so that a concave-convex area or a frosted surface layer is formed, and a larger friction force is provided in the clamping process, so that the locking and fixing of the supporting leg 3 are more stable and reliable.
It is noted that the adduction connecting section 201 here extends from one end of the connecting mount 2 to the other end, so that the support foot 3 can be fixed in any position relative to the connecting mount 2; when the position of the supporting leg 3 needs to be adjusted, only a small-amplitude reverse rotation of the bolt is required, so that the clamping plate and the supporting leg 3 main body can be converted into a loose state relative to the adduction connecting section 201, and the translation adjustment action can be conveniently performed. In adjusting the position of the support leg 3, since the lateral dimension of the engagement plate member in the flat state is larger than the width of the opening of the guide mounting groove 2a, the support leg 3 is mounted on the connection mount 2 in an upright state even during adjustment, and therefore the structure is advantageous in that the support leg 3 is not separated from the connection mount 2 during adjustment, and thus, the support leg 3 does not need to be supported again in an auxiliary shape or aligned in position for fastening mounting again.
In order to increase the contact area between the supporting leg 3 and the connection mounting frame 2, further improving the bearing stability, a flat bearing connection plate 3a may be fixed on the upper portion of the supporting leg 3, the front and rear ends of the bearing connection plate 3a respectively extend outwards along the whole trend of the connection mounting frame 2, and the bearing connection plate 3a is connected with the limit connection member 7a at the part extending outwards. Therefore, a plurality of clamping plate members serving as limiting connecting pieces 7a can be connected and installed on one supporting leg 3 at the same time, even if one clamping plate member fails in connection, the position of the supporting leg 3 can be continuously maintained without loosening, and correction and fastening of the failure part of the supporting leg can be conveniently carried out again in overhauling and maintenance.
For the whole chain machine, the chain machine at least comprises a pair of adjustable positioning supporting mechanisms of the chain machine, which are arranged on two sides of the chain machine in a row, and the extending directions of the adjustable positioning supporting mechanisms of the chain machine are parallel and symmetrical to each other. In the adjustable positioning supporting mechanism of the chain machine at two sides, the upper part of each connecting installation frame 2 is provided with a conveying belt 1, meanwhile, a driving device 4 is fixedly installed between the connecting installation frames 2 which are respectively arranged at two sides, and the driving device 4 drives the conveying belts 1 at two sides to operate through a transmission assembly.
Due to the existence of the corresponding structure of the first limit connecting assembly 7, a second limit connecting assembly 8 similar to the first limit connecting assembly 7 can be formed on the driving device 4 by utilizing a part of the connecting mounting frame 2, so that the connection fixing and position adjusting functions between the driving device 4 and the connecting mounting frame 2 are realized. Specifically, the driving device 4 includes a mounting frame 4a that spans and connects between two adjustable positioning supporting mechanisms of the chain machine, and the mounting frame 4a is connected with the connection mounting frame 2 through the second limiting connection component 8. The second limiting connecting component 8 comprises extending connecting sections which are located at two sides of the mounting frame 4a and extend outwards and are respectively arranged below the connecting mounting frame 2, and is similar to the first limiting connecting component 7, a plurality of clamping plates provided with through holes are arranged in the guide mounting groove 2a in a flat state, and meanwhile, the clamping plates are locked and fixed by using a threaded structure after penetrating through the extending connecting sections and the clamping plates from bottom to top in sequence by using bolts, so that the lower surfaces of the clamping plates and the upper surfaces of the extending connecting sections are tightly clamped and fixed at the upper side and the lower side of the adduction connecting section 201. The conversion of the driving device 4 between the locked state and the released state relative to the connecting mounting frame 2 can be realized by rotating the adjusting connecting piece 7b in the second limit connecting assembly 8 in the forward direction or the reverse direction in a similar manner to the position of the adjusting supporting leg 3, and the whole driving device 4 can be conveniently and quickly adjusted in the state of not disengaging.
A transverse driving motor is arranged in the middle of the mounting frame 4a in the driving device 4, and an output shaft which spans two sides and is connected with the mounting frame 2 is also arranged below the driving motor; the output end of the driving motor drives the output shaft to rotate through a gear meshing structure, and the two ends of the output shaft drive the conveyer belts 1 on the two sides to operate through gear tooth transmission mechanisms respectively or drive the conveyer belts 1 to operate through direct laminating friction.
At the bottom of the connection mount 2 on each side, several support feet 3 are mounted along the direction in which they extend to ensure the overall support effect for the chain machine. It is considered that in practice the ground or the supporting surface of the platform on which the chain is placed is not necessarily perfectly flat, and the presence of errors in the manufacture of the components and the installation of the connection results in the spacing between the connection mounting 2 with respect to the ground or the supporting surface of the bottom not being exactly the same in every position. At this time, the height of each supporting leg 3 needs to be adjusted adaptively so as to avoid over-positioning during supporting or uneven stress of the whole chain machine.
In view of the above, the supporting leg 3 may be configured to include a first bearing section 301 located at an upper side for connection with the connection mount 2 and a second bearing section 302 located at a lower side for connection with the ground, a telescopic adjustment mechanism 303 for changing the height of the supporting leg 3 in a vertical direction is formed between the first bearing section 301 and the second bearing section 302, and the second bearing section 302 may pass upward through the guide mounting groove 2a and enter a hollow portion inside the connection mount 2 when the height of the supporting leg 3 is changed by the telescopic adjustment mechanism 303. Specifically, the telescopic adjusting mechanism 303 includes an adjusting stud disposed on the upper portion of the second bearing section 302 and extending upwards to form a protrusion, a frame portion disposed on the lower portion of the first bearing section 301 and provided with a through hole along a vertical direction, and an adjusting nut screwed on the adjusting stud, where the frame portion is sleeved on the adjusting stud through the through hole, and the adjusting nut and the frame portion mutually abut to realize a supporting function on the connecting mounting frame 2. When the adjusting nut is rotated in one direction, the adjusting nut moves upwards, and the first bearing section 301 of the supporting leg 3 moves upwards relative to the second bearing section 302 by propping up the frame part, so that the supporting leg 3 is integrally elongated; correspondingly, the adjusting nut can be reversely rotated, so that the whole supporting leg 3 is shortened.
Further, in order to avoid the separation of the first bearing section 301 and the second bearing section 302 of the supporting leg 3 fixed on the connection mounting frame 2 during the whole supporting and moving process of the chain machine, the lower portion of the frame portion for cooperation may be configured as a horizontal flat plate, and a pair of adjusting nuts screwed on the adjusting studs are simultaneously installed on the upper side and the lower side of the flat plate, so that the reliability of the supporting leg 3 as a whole structure in the vertical direction is ensured while the telescopic adjusting function of the supporting leg 3 is ensured. It should be noted that, in order to provide a certain height space for the lifting adjustment of the support leg 3, a certain clearance space should be ensured between the bottom of the mounting bracket 4a and the ground when designing and manufacturing the mounting bracket 4a structure.
Because the connecting installation frames 2 positioned at the two sides are in a slender and straight state, deformation and damage are easy to occur when the chain machine is extruded by external force collision, and the whole operation of the chain machine is not smooth. Therefore, a plurality of mounting hole grooves 2b arranged along the extending direction of the connecting mounting frame 2 are formed in the connecting mounting frame 2, and the mounting hole grooves 2b penetrate through the left and right side surfaces of the connecting mounting frame 2 at the same time. The two sides of the connecting installation frame 2 are fixedly provided with the supporting pull rods 5 which are used for strengthening the structure between the opposite holes and grooves, and the pair of connecting installation frames 2 can be ensured to be in a state of extending in parallel with each other by installing the supporting pull rods 5 at a certain distance between the two connecting installation frames 2. Furthermore, by using the mounting hole slots 2b, the protection plates 6 facing the outer sides of the two connecting mounting frames 2 can be fixed respectively, so as to play a role in shielding and protecting the conveyor belt 1.
While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
