Description

Technical Field

[0001] The utility model relates to the technical field of stacking equipment, in particular to a stacker with a wide cargo platform. Background Art

[0002] A stacker is a type of equipment used in warehouses, primarily for moving goods to target locations and stacking them together to improve warehouse space utilization. A stacker generally consists of a column, a horizontal travel mechanism, a lifting mechanism, a cargo platform, a fork, and an electrical control system. The lifting mechanism is used to drive the cargo platform up and down along the column. Stacking large goods usually requires a large cargo platform (i.e., a wide cargo platform). However, as the size of the cargo platform increases, the load requirements for the lifting mechanism also increase accordingly. Therefore, it is necessary to research a stacker that is suitable for wide cargo platforms. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a stacker with a wide cargo platform, which can effectively enhance the lifting stability of the wide cargo platform by improving the lifting mechanism.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a stacker with a wide width cargo platform, comprising

[0005] A frame comprising an upper beam, a lower beam, and a support frame located between the upper beam and the lower beam;

[0006] Two upright posts are arranged opposite to each other, and the upper and lower ends of each upright post are connected to the upper beam and the lower beam respectively;

[0007] A cargo platform is located between the two columns, and includes a tray. Both ends of the tray are provided with sliding seats arranged in a one-to-one correspondence with the columns, and the sliding seats are slidably arranged on the corresponding columns;

[0008] The lifting mechanism is arranged in a one-to-one correspondence with the sliding seat, so as to drive the corresponding sliding seat to slide along the column; the lifting mechanism includes a driving member, a winding drum, a fixed pulley, a first movable pulley, a second movable pulley, a first traction rope, and a second traction rope; the winding drum is arranged on the support frame and can rotate under the action of the driving member; the fixed pulley is located on the upper beam, and the first movable pulley and the second movable pulley are arranged side by side on the sliding seat, one end of the first traction rope is fixedly connected to the upper beam after passing through the first movable pulley, and the other end is wound around the fixed pulley after passing through the winding drum; one end of the second traction rope is fixedly connected to the upper beam after passing through the second movable pulley, and the other end is wound around the winding drum after passing through the fixed pulley.

[0009] The beneficial effects of the stacker with a wide cargo platform of the utility model are:

[0010] First, two columns are set on both sides of the cargo platform, and the cooperation of two sliding seats and the columns is used to improve the stability of the cargo platform's up and down movement; then, two lifting mechanisms are used to jointly drive the movement of the cargo platform, which can reduce the load requirement of a single lifting mechanism to ensure the stability of driving a large-sized cargo platform; in the lifting mechanism, when the driving member drives the winding drum to rotate, the first traction rope and the second traction rope can be wound onto the winding drum, so that the first movable pulley and the second movable pulley can drive the cargo platform to move up. The setting of two movable pulleys (first movable pulley, second movable pulley) and two traction ropes (first traction rope, second traction rope) can share the traction force of the lifting mechanism on the cargo platform, thereby reducing the risk of traction rope breakage. At the same time, the setting of two traction ropes can also prevent the cargo platform from falling when a single traction rope breaks.

[0011] Specifically, the pallet includes a pallet base and a cargo frame. The cargo frame is located above the pallet base and is movable along the width of the pallet base. The sliding seats are fixedly connected to both ends of the pallet base along its length. The cargo frame is used to carry cargo to be transported. The cargo frame is configured to be movable along the width of the pallet base to facilitate horizontal transport of cargo.

[0012] Specifically, the pallet base is provided with a plurality of pallet rails along its length, and the cargo frame is provided with a plurality of slide bars corresponding to the pallet rails. The plurality of slide bars are capable of synchronous movement along the corresponding pallet rails under the action of a synchronous transmission mechanism. The coordination of the plurality of pallet rails and the plurality of slide bars enhances the stability of the cargo frame as it moves on the pallet base.

[0013] Furthermore, a supporting plate for supporting the cargo frame is provided at the upper end of the pallet bottom plate near the sliding seat to enhance the supporting stability of the cargo frame plate.

[0014] Specifically, the sliding seat includes a first vertical plate and a second vertical plate that are arranged opposite to each other, a pulley mounting seat for mounting the first movable pulley and the second movable pulley is provided between the first vertical plate and the second vertical plate, and a space for the column to pass through is provided between the first vertical plate and the second vertical plate.

[0015] Furthermore, an upper guide wheel assembly and a lower guide wheel assembly are respectively mounted on opposite sides of the first and second risers, and both the upper guide wheel assembly and the lower guide wheel assembly can abut against the column. The arrangement of the upper guide wheel assembly and the lower guide wheel assembly can guide the movement of the sliding seat on the column.

[0016] Furthermore, the upper and lower guide wheel assemblies each include a mounting plate, on which are mounted a first guide wheel, a second guide wheel, and a third guide wheel, respectively. The first and second guide wheels are arranged opposite each other and can abut on opposite sides of the column. The third guide wheel is arranged perpendicular to the first guide wheel and can abut on two perpendicular side surfaces of the column. The first, second, and third guide wheels can abut on three side surfaces of the column, thereby enhancing the stability of the sliding seat on the column.

[0017] Furthermore, the lower beam is equipped with a detection assembly for detecting whether the cargo platform is tilted. This detection assembly includes two distance sensors, located near each end of the cargo platform, to measure the distance between the bottom of the cargo platform and the lower beam. This detection assembly facilitates timely adjustment of the driving force of the two lifting mechanisms, reducing the probability of the cargo platform tilting during lifting and ensuring smooth movement of the cargo platform.

[0018] Furthermore, a maintenance platform is installed on the support frame near the upper beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0031] Example

[0032] See attached Figure 1-2 As shown, the utility model is a stacker with a wide cargo platform, comprising a frame 1, columns 2, a cargo platform 3, and a lifting mechanism 4. The frame 1 comprises an upper beam 11, a lower beam 12, and a support frame 13 located between the upper beam 11 and the lower beam 12. Two columns 2 are arranged opposite to each other, and the upper and lower ends of each column 2 are respectively connected to the upper beam 11 and the lower beam 12. The cargo platform 3 is located between the two columns 2, and includes a tray 31. Both ends of the tray 31 are respectively provided with sliding seats 32 arranged in a one-to-one correspondence with the columns 2, and the sliding seats 32 are slidably arranged on the corresponding columns 2. The lifting mechanism 4 is arranged in a one-to-one correspondence with the sliding seats 32 to drive the corresponding sliding seats 32 to slide along the columns 2.

[0033] For details, see the attached Figure 2-5 As shown, the lifting mechanism 4 includes a driving member 41, a winding drum, a fixed pulley 42, a first movable pulley 43, a second movable pulley 44, a first traction rope, and a second traction rope. The winding drum is mounted on the support frame 13 and can rotate under the action of the driving member 41. The fixed pulley 42 is located on the upper beam 11, and the first movable pulley 43 and the second movable pulley 44 are arranged side by side on the sliding seat 32. One end of the first traction rope passes around the first movable pulley 43 and is fixed to the upper beam 11, and the other end passes around the fixed pulley 42 and is wound around the winding drum. One end of the second traction rope passes around the second movable pulley 44 and is fixed to the upper beam 11, and the other end passes around the fixed pulley 42 and is wound around the winding drum. By way of example, the driving member 41 can be a motor.

[0034] During operation, the two lifting mechanisms 4 are activated simultaneously. The winding drum then rotates under the action of the driving member 41, driving the first and second traction ropes to be wound onto the winding drum. The first and second movable pulleys 43 and 44 then drive the sliding seat 32 to move upward along the column 2, thereby achieving the upward movement of the cargo platform 3. First, two columns 2 are set on both sides of the cargo platform 3, and the two sliding seats 32 cooperate with the columns 2 to improve the stability of the up and down movement of the cargo platform 3. Then, the two lifting mechanisms 4 are used to jointly drive the movement of the cargo platform 3, which can reduce the load requirement of a single lifting mechanism 4 and ensure the stability of driving a large-sized cargo platform. In the lifting mechanism 4, the two movable pulleys (the first movable pulley 43 and the second movable pulley 44) and the two traction ropes (the first traction rope and the second traction rope) can distribute the traction force of the lifting mechanism 4 on the cargo platform 3, thereby reducing the risk of traction rope breakage. At the same time, the provision of two traction ropes can also prevent the cargo platform 3 from falling if a single traction rope breaks.

[0035] Because the present application employs two lifting mechanisms 4 to drive two sliding seats 32, respectively, during the lifting process of the cargo platform 3, to prevent the cargo platform 3 from tilting due to inconsistent movement of the two sliding seats 32, in some embodiments, the lower beam 12 is further provided with a detection assembly for detecting whether the cargo platform 3 is tilted. The detection assembly includes two distance measuring sensors, one located near each end of the cargo platform 3, to measure the distance between the bottom of the cargo platform 3 and the lower beam 12. The provision of the detection assembly facilitates timely adjustment of the driving force of the two lifting mechanisms 4, thereby reducing the probability of tilting of the cargo platform 3 during the lifting process and ensuring the smooth movement of the cargo platform 3. For example, when the detection assembly detects that the height of one end of the cargo platform 3 is too low, the lifting mechanism 4 at that end of the cargo platform 3 continues to operate, while the lifting mechanism 4 at the other end of the cargo platform 3 pauses to adjust the height of the cargo platform 3. When the heights of the two ends of the cargo platform 3 are adjusted to the same, the two lifting mechanisms 4 are synchronized again.

[0036] In some embodiments, see Appendix Figure 4 As shown, the pallet 31 includes a pallet base 311 and a cargo frame 312. The cargo frame 312 is located at the upper end of the pallet base 311 and is movable along the width of the pallet base 311. Sliding seats 32 are fixedly connected to both ends of the pallet base 311 along its length. The cargo frame 312 is used to carry the cargo to be transported. The cargo frame 312 is configured to be movable along the width of the pallet base 311 to facilitate horizontal transport of the cargo.

[0037] Furthermore, the pallet base 311 is provided with a plurality of pallet guide rails 3111 along its length, and the cargo frame 312 is provided with a plurality of slide bars 3121 corresponding to the pallet guide rails 3111. The plurality of slide bars 3121 can be moved synchronously along the corresponding pallet guide rails 3111 under the action of the synchronous transmission mechanism 33. The coordination of the plurality of pallet guide rails 3111 and the plurality of slide bars 3121 improves the stability of the movement of the cargo frame 312 on the pallet base 311, and the provision of the synchronous transmission mechanism 33 further enhances the synchronization of the movement of the plurality of slide bars 3121. It should be noted that the synchronous transmission mechanism 33 is conventional technology and will not be described in detail in this embodiment.

[0038] Furthermore, a supporting plate 3112 for supporting the cargo frame plate 312 is provided at the upper end of the tray bottom plate 311 near the sliding seat 32 to enhance the supporting stability of the cargo frame plate 312 .

[0039] In some embodiments, see Appendix Figure 5 As shown, the sliding seat 32 includes a first vertical plate 321 and a second vertical plate 322 arranged opposite each other. A pulley mounting seat 323 for mounting the first movable pulley 43 and the second movable pulley 44 is located between the first and second vertical plates 321, 322. A space is provided between the first and second vertical plates 321, 322 for the column 2 to pass through. Furthermore, an upper guide wheel assembly and a lower guide wheel assembly are mounted on opposing sides of the first and second vertical plates 321, 322, respectively. Both the upper guide wheel assembly and the lower guide wheel assembly can abut against the column 2. The arrangement of the upper and lower guide wheel assemblies guides the movement of the sliding seat 32 on the column 2.

[0040] In some embodiments, both the upper and lower guide wheel assemblies include a mounting plate 324, on which are respectively provided a first guide wheel 325, a second guide wheel 326, and a third guide wheel 327. The first guide wheel 325 and the second guide wheel 326 are arranged opposite each other and can abut on opposite sides of the column 2. The third guide wheel 327 is arranged perpendicular to the first guide wheel 325 and can abut on two perpendicular side surfaces of the column 2. The first guide wheel 325, the second guide wheel 326, and the third guide wheel 327 can abut on three side surfaces of the column 2, thereby enhancing the movement stability of the sliding seat 32 on the column 2.

[0041] In some embodiments, see Appendix Figure 1-2 As shown, a maintenance platform 5 is installed on the support frame 13 near the upper beam 11 to facilitate the maintenance of the upper end of the stacker.

[0042] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
