As shown in fig. 1, one embodiment of the present invention provides a height-adjustable conveyor, which may include: a bracket 1, a conveying rack 2 and a first number of movable support legs 3;
wherein the first number is a positive integer, and the vertical heights of different movable supporting legs 3 are different;
one end of the conveying frame 2 is provided with a first connecting piece 4, and the other end is respectively provided with a second connecting piece 5 and a first number of third connecting pieces 6;
the bracket 1 comprises a first supporting leg 7 and a second supporting leg 8, and the vertical height of the second supporting leg 8 is not smaller than the vertical height of the first supporting leg 7;
wherein the first number of movable legs 3 and the first number of third connecting pieces 6 are in one-to-one correspondence;

the second connecting piece 5 is used for being connected with the second supporting leg 8 so that the conveying height of the conveyor is dependent on the vertical height of the second supporting leg 8;
each movable supporting leg 3 is used for connecting the lower end with the second supporting leg 8, and the upper end is connected with the conveying frame 2 through a corresponding third connecting piece 6, so that the conveying height of the conveyor depends on the vertical height of the second supporting leg 8 and the vertical height of the conveyor;
the conveying height of the conveyor meets the formula I;
the first formula includes: h is a max ≤x
Wherein h is max The conveying height of the conveyor is determined by the vertical height of the second supporting leg 8 and the vertical height of the target movable leg, wherein the vertical height of the target movable leg is greater than the vertical height of any other movable leg, and x is the horizontal distance between the first supporting leg 7 and the second supporting leg 8.
The embodiment of the invention provides a conveyor with adjustable height, which comprises a bracket, a conveying frame and a plurality of movable supporting feet with different vertical heights; one end of the conveying frame is provided with a first connecting piece, and the other end of the conveying frame is provided with a second connecting piece and a plurality of third connecting pieces which are in one-to-one correspondence with a plurality of movable supporting legs; the bracket comprises a first supporting leg and a second supporting leg, and the vertical height of the second supporting leg is not smaller than that of the first supporting leg; the first supporting leg is connected with the conveying frame through a first connecting piece; the second connecting piece is used for connecting the second supporting leg so that the conveying height is dependent on the vertical height of the second supporting leg; the lower ends of the movable supporting legs are connected with the second supporting legs, and the upper ends of the movable supporting legs are connected with the conveying frame through corresponding connecting pieces, so that the conveying height is dependent on the vertical heights of the movable supporting legs and the second supporting legs; the maximum conveying height is not greater than the horizontal distance between the two supporting feet. As the conveying device can be adjusted to different conveying heights according to the requirement, the conveying requirements of different conveying heights can be met at the same time.
Referring to fig. 1, since the conveyor is a three-dimensional product, the movable legs should be present in pairs and located on both sides of the conveyor frame, respectively. Similarly, the above-mentioned respective connectors, supporting legs, etc. are also present in pairs. In the embodiments of the present invention, for convenience of description, the respective components on one side of the carrier will be generally described.
In the embodiment of the invention, the conveying frame can be directly connected with the second supporting leg or indirectly connected with the second supporting leg through any movable supporting leg. Because the vertical heights of different movable supporting legs are different, when the connection modes are different or the connected movable supporting legs are different, the conveying height of the conveyor is correspondingly changed. Thus, the number of the conveying heights of the conveyor is the sum of the first number and 1.
Referring to fig. 1, the number of the movable legs is 2, i.e. the first number is 2. Therefore, the number of the values of the conveying height of the conveyor shown in fig. 1 is 3, and the current conveying height of the conveyor shown in fig. 1 depends on the vertical height of the second supporting leg and the vertical height of the short movable leg, while the long movable leg is currently in a standby state.
Of course, the individual movable legs in the standby state can also be stored separately from the conveyor and used when required. For example, referring to the conveyor shown in fig. 2, the conveyor includes only one movable leg, and the movable leg can be stored independently when not in use.
Referring to fig. 1, when each supporting leg and each movable leg are connected to the conveying frame, the supporting legs are connected through corresponding connecting pieces arranged on the conveying frame. In order to realize different conveying heights of the conveyor, the two supporting legs are respectively positioned at two ends of the conveying frame, and the movable legs are sequentially positioned at the same end of the conveyor.
As can be seen from fig. 1, in order to cope with the possible case of horizontal conveyance, the vertical heights of the first support leg and the second support leg may be made the same, so that when the second support leg is connected to the second connecting member, the conveyance height of the conveyor is relatively 0, so that horizontal conveyance can be supported.
Of course, when horizontal conveying is not required to be considered, the vertical height of the second supporting leg is larger than that of the first supporting leg. Furthermore, the minimum value of the conveying height to be used is known, and the conveying height of the second support leg can be determined as required based on the minimum value. For example, the conveying height of the second support leg when connected to the second connecting member may be equal to the minimum value or less than the minimum value. However, in order to be able to achieve as much transport height as possible, the vertical height of the second support leg is preferably not too great.
Considering that the conveying elevation angle is overlarge when the conveying height is overlarge, the articles are easy to fall down based on self gravity in the process of conveying the articles and are unfavorable for moving along the conveying direction, and the maximum conveying height can be limited to be not more than the horizontal distance between two supporting feet. The maximum conveying height is determined by the movable support leg with the maximum vertical height and the second support leg.
In summary, the conveyor provided by the embodiment of the invention can adjust the conveying height as required, so that the conveyor is suitable for application scenes with different conveying height requirements, and has strong applicability.
In one embodiment of the present invention, referring to fig. 1, the carriage 2 includes: a conveyor belt 9, a drive assembly 10 and a mounting 11 provided with said first link 4, said second link 5 and each of said third links 6;
wherein the conveyor belt 9 and the drive assembly 10 are both mounted on the mounting frame 11;
the driving assembly 10 is used for driving the conveying belt 9 to move.
In detail, the conveyer belt is installed on the mounting bracket, and the mounting bracket can be connected with the support through connecting pieces and the like, and the fixing bracket for supporting the conveyer belt to move is formed by the mounting bracket and the connecting pieces. The driving assembly can drive the conveying belt to move relative to the fixed support, so that conveyed objects on the conveying belt are driven to move, and the purpose of conveying the objects is achieved.
In one embodiment of the present invention, referring to fig. 1, the driving assembly 10 includes: a motor 12, a driving shaft 13 and a driven shaft 14;
the driving rotating shaft 13 and the driven rotating shaft 14 are respectively installed at two ends of the installation frame 11, and the distance between the driving rotating shaft 13 and the first connecting piece 4 is greater than the distance between the driven rotating shaft 14 and the first connecting piece 4;
the conveying belt 9 is sleeved on the driving rotating shaft 13 and the driven rotating shaft 14;
the output shaft of the motor 12 is connected with the driving rotating shaft 13;
the motor 12 is configured to drive the driving shaft 13 to rotate, so that the driving shaft 13 that rotates drives the conveyor belt 9 to move, and drives the driven shaft 14 to rotate.
In detail, the driving rotating shaft and the driven rotating shaft are respectively arranged at two ends of the mounting frame, and the motor is arranged at the position close to the driving rotating shaft so as to directly drive the driving rotating shaft to rotate. Because the conveyer belt is similar to the annular cover of establishing with fastening on initiative pivot and driven pivot, so when the initiative pivot rotated, based on the frictional force between initiative pivot and conveyer belt, can drive the conveyer belt and remove based on initiative pivot direction of rotation, and then based on the frictional force between driven pivot and conveyer belt, the conveyer belt of removal can drive driven pivot and rotate based on conveyer belt direction of movement, so the effect realizes the rotation of conveyer belt around two pivots.
Because the conveyor belt rotates continuously around the two rotating shafts, articles placed on the conveyor belt can be conveyed from one end of the conveyor to the other end of the conveyor belt. Further, the article is simultaneously conveyed from a low place to a high place based on the conveying height of the conveyor.
In one embodiment of the present invention, referring to fig. 1, the mounting frame 11 includes: a first mounting plate 15 and a second mounting plate 16 arranged symmetrically;
wherein, at least one opening 17 is arranged on the first mounting plate 15, and an opening 17 corresponding to each opening 17 is arranged on the second mounting plate 16;
the center line of any two corresponding openings 17 is perpendicular to the first mounting plate 15 and the second mounting plate 16.
In detail, on the basis of guaranteeing the mounting bracket fastness, can set up a plurality of trompils on the two symmetrical mounting panels of mounting bracket, can lighten the weight of mounting bracket on the one hand to make things convenient for the transport to remove the conveyer and practice thrift the product consumptive material, on the other hand can also play pleasing to the eye effect.
Through set up the trompil of same quantity and one-to-one symmetry on two symmetrical mounting panels, can guarantee that the atress of two mounting panels is even unanimous.
In one embodiment of the present invention, referring to fig. 1 and 2, the conveyor belt 9 includes: a net chain;
any of the openings 17 includes: the first side edge, the second side edge and two arc edges respectively connected with the first side edge and the second side edge;
for a first plane including the first side and a second plane including the second side, the first plane and the second plane are both perpendicular to the first mounting plate 15, and either surface of the net chain is located between the first plane and the second plane.
Referring to fig. 2, there is shown in fig. 2 a mounting plate on one side, the mounting plate on the other side being hidden by the mounting plate, and since the two mounting plates are symmetrically arranged and the openings therein are symmetrically arranged one by one, the corresponding two openings remain substantially overlapping from the perspective of fig. 2.
In the embodiment of the invention, the space region where the holes are formed and the space region where the net chain is formed are crossed, so that the holes can be formed when the net chain is required to be installed, replaced, maintained and cleaned.
On the one hand, in order to facilitate the processing of the net chain as required by the opening, the shape of the opening can be designed to be semicircular at both ends and rectangular in the middle.
On the basis of this, on the other hand, in order to facilitate the handling of the wire links as desired by means of openings, the intersection area of the two can be increased as much as possible. For example, in the embodiment of the present invention, for any opening shown in fig. 2, an upper straight edge and a lower straight edge of the opening are the first side edge and the second side edge, respectively, and the first plane may be a plane including the upper straight edge and perpendicular to the paper surface, and the second plane may be a plane including the lower straight edge and perpendicular to the paper surface. Based on this, it can be defined that either surface of the net chain lies between the two planes. Preferably, for ease of handling, either surface of the net chain is parallel to both planes.
In one embodiment of the present invention, referring to fig. 1 and 2, the conveyor further includes: a material frame 18 mounted on the carriage 2;
wherein the distance from the material frame 18 to the first connecting piece 4 is smaller than the distance from the material frame 18 to the second connecting piece 5.
In detail, the material frame is utilized to hold material when transporting smaller volumes of bulk material. Of course, the material frame should be located at the relatively lowest position of the conveyor belt.
In one embodiment of the present invention, referring to fig. 1, two bolt holes are disposed at the lower end of each movable leg 3, and the two bolt holes are sequentially disposed along the length direction of the movable leg 3;
the upper end of the second supporting leg 8 is provided with two bolt holes corresponding to the two bolt holes.
In detail, the movable leg and the second supporting leg can be connected by means of a bolt and nut group. Meanwhile, considering that the fastening effect of one bolt and nut group is slightly poor, connection can be achieved through two bolt and nut groups. Thus, the upper end of the second supporting leg is provided with two bolt holes in an up-and-down distribution mode, and correspondingly, the lower end of the movable supporting leg is provided with two bolt holes in an up-and-down distribution mode.
Of course, in other embodiments of the present invention, the connection between the two may be implemented in other manners, for example, the connection may be implemented by a snap-fit manner.
In one embodiment of the present invention, please refer to fig. 1, the transportable length of the carriage 2 satisfies the formula two;
the formula II comprises:
wherein L is the conveyable length, and h is the conveying height of the conveyor determined by the vertical height of the second supporting leg 8 and the vertical height of any one of the movable legs 3.
Referring to fig. 1, the transportable length of the carriage should be long enough to support the transport of the transported articles from one low level to another high level. For example, articles from a low-level pipeline are transported to a high-level pipeline, and the horizontal distance and the vertical distance between the two ends are different. The uppermost end of the conveyor belt may be positioned above or horizontally adjacent to the high-level pipeline such that after the articles are conveyed to the uppermost end, the respective articles may fall onto or be conveyed horizontally onto the high-level pipeline.
In an embodiment of the present invention, referring to fig. 1 and 2, the bracket 1 further includes: a horizontal chassis 19 with one end connected to the first support leg 7 and the other end connected to the second support leg 8.
In detail, referring to fig. 1, the horizontal underframe is respectively connected with two supporting feet, so that the stability of the support can be further enhanced, and the stable operation of the conveying operation of the conveyor is ensured.
Because conveyors typically have a certain conveying height, they occupy a large number of spatial positions. Therefore, when the conveyor is not used for a long time, the conveyor can be folded to a certain extent to reduce the space occupation under the condition that the use frequency of the conveyor is relatively low. In this way, the conveyor described above can be designed as a collapsible conveyor. In the embodiment of the present invention, considering that the movable leg and the second supporting leg are the main influencing factors influencing the space occupation of the conveyor, the portion can be processed to fold the conveyor, and preferably, at least two folding modes can exist:
mode 1: the horizontal underframe and the second supporting leg are detachably connected and are connected or separated by controlling the connection and separation of the horizontal underframe and the second supporting leg so as to fold the conveyor as required;
mode 2: the horizontal underframe and the second supporting leg are rotatably connected, and the conveyor is folded according to the need by controlling the rotation angle between the horizontal underframe and the second supporting leg.
In detail, for the above embodiment 1:
in one embodiment of the invention, the horizontal chassis 19 is detachably connected to the second support leg 8.
For example, a secure connection between the horizontal chassis and the second support foot may be achieved by means of bolts. Correspondingly, when the bolt is removed, the horizontal underframe and the second supporting leg can be separated. The second supporting leg separated from the horizontal underframe can be stored independently, can also be connected with the second connecting piece to be suspended on the conveyor, and can also be connected with any movable supporting leg connected with the corresponding third connecting piece to be suspended on the conveyor.
Because the horizontal underframe and the second supporting feet are not connected and cannot provide a certain conveying height, the occupied space of the conveyor is relatively minimum.
In detail, for the above embodiment 2:
in an embodiment of the present invention, referring to fig. 1 and 2, the bracket 1 further includes: hinge 20 connecting the horizontal chassis 19 and the second supporting leg 8 respectively;
when the hinge 20 is in an open state, two blades of the hinge 20 are perpendicular to each other;
when the hinge 20 is in a closed state, two blades of the hinge 20 are parallel.
In detail, referring to fig. 1 and 2, the horizontal chassis and the second supporting leg may be connected by a hinge. As shown in figure 1, when the hinge is completely opened, the horizontal underframe is vertical to the second supporting leg, and the included angle between the horizontal underframe and the second supporting leg is 90 degrees, at this time, the conveying height can be adjusted by different movable supporting legs or unsuitable movable supporting legs according to the requirement.
As shown in fig. 2, when the hinge is closed, the horizontal chassis and the second supporting leg are parallel, the included angle between the two is 0 °, and the second supporting leg or the second supporting leg connected with a movable supporting leg can be located between the mounting frame and the horizontal chassis, at this time, the occupied space of the conveyor is relatively minimum.
Referring to fig. 2, when the hinge is closed, the conveyor frame and the support frame are kept connected by the first connecting piece. When the screw between the first connecting piece and the first supporting leg is not locked, the relative position between the conveying frame and the supporting leg is easy to change, so that inconvenience is caused to conveying of the conveyor. Therefore, when the conveying frame is in a folding state, the fixing connection between the conveying frame and the support can be realized through the locking part, so that the conveying machine can be conveniently carried.
Based on this, in one embodiment of the present invention, referring to fig. 3, the bracket 1 further includes a locking member 21;
wherein the locking member 21 comprises: a spring 22 connected to the horizontal chassis 19, an L-shaped handle 23 connected to the spring 22, a locking shaft 24 connected to the L-shaped handle 23, and a locking ball 25 connected to the locking shaft 24;
wherein, the carriage 2 is provided with a locking hole 26, and the locking hole 26 comprises: a first circular hole 27, a second circular hole 28, and a channel 29 connected to the first circular hole 27 and the second circular hole 28, respectively;
wherein the diameter of the locking ball 25 is larger than the diameter of the locking shaft 24, the height of the channel 29 and the diameter of the second circular hole 28, and smaller than the diameter of the first circular hole 27, respectively;
the diameter of the locking shaft 24 is smaller than the height of the channel 29 and the diameter of the second circular hole 28, respectively;
the diameter of the second circular hole 28 is larger than the height of the channel 29;
when the locking shaft 24 penetrates through the second round hole 28, the spring 22 is in a stretched state, and the vertical distance between the second round hole 28 and the horizontal chassis 19 is smaller than the vertical distance between the first round hole 27 and the horizontal chassis 19.
Referring to fig. 3 and 4, the L-shaped handle of the locking member is connected to the horizontal chassis through a spring, so that a user can apply a certain force to control the movement of the L-shaped handle after holding the L-shaped handle, and further drive the locking shaft and the locking ball on the L-shaped handle to move synchronously.
For example, a user may control the L-shaped handle as desired to cause the locking shaft to drop into the second circular aperture after passing through the first circular aperture and the channel in sequence. Because the diameter of the second round hole is smaller than that of the locking ball, the locking ball can be clamped when the locking shaft penetrates through the second round hole, and therefore the fixed connection between the conveying frame and the support is achieved.
As shown in fig. 3 and 4, when no external force is applied to the locking member, the spring is in a normal state at present, and when the locking shaft penetrates through the second circular hole, the spring is in a stretched state.
Therefore, in the embodiment of the invention, through the cooperation of the locking piece and the locking hole, the further connection between the conveying frame and the support frame can be realized, so that the conveying machine is convenient to carry.
