Description

Technical Field

[0001] The utility model relates to the technical field of logistics conveying equipment, and particularly relates to a loading platform of a heavy hoist. Background Art

[0002] With the increasing development of warehousing logistics, in an automated three-dimensional warehouse, more and more manufacturers adopt the method of intensive layered storage of goods. A hoist is a device used for lifting and conveying materials, and is widely used in places such as warehouses, logistics centers, and production lines. It can effectively improve the transportation efficiency of materials, reduce labor costs and labor intensity.

[0003] The existing heavy hoists are mainly in the form of a four-column structure. The loading platform uses the four columns as guide rails respectively for vertical lifting. This working condition has high requirements for the parallelism of the metal structure, the vertical height of the columns, and the overall installation accuracy of the car hoist. When lifting and running, the guide wheel sets of the car platform are prone to uneven stress, extremely easy to wear, and cannot guarantee the working plane accuracy of the car platform, affecting the horizontal docking of the loading platform and the shelf track.

[0004] For example: The Chinese utility model patent with the publication number of CN216918495U discloses a loading platform with double servo motors. The loading platform includes a loading unit, two fence units, two transmission units, and several limiting units; wherein, the two fence units are arranged at both ends of the loading unit; the two transmission units are arranged at both ends of the loading unit, and their shaft elements pass through the corresponding fence units and are located outside the loading unit; this loading platform eliminates the limitation that the frequency conversion motor occupies the bottom space or the top space, greatly shortening the occupied space of the loading platform for the bottom or the top, but the structural strength of the fence unit of this loading platform is relatively low, and it is easy to cause the deformation of the loading platform due to uneven force distribution when transporting heavy goods. Content of the Utility Model

[0005] The purpose of the utility model is to provide a loading platform of a heavy hoist to improve the overall structural strength of the loading platform and be suitable for the transportation of heavy goods.

The lifting frame includes two frame-type side frames on the left and right, two upper cross beams connected to the upper ends of the two side frames, and two lower cross beams connected to the lower ends of the two side frames. The conveying component is fixed on the two lower cross beams. At least two groups of the conveying components are distributed at intervals left and right, and the two groups of the conveying components are synchronously driven by a driving mechanism; guide wheel components are respectively arranged at the upper and lower ends of the side frame, the guide wheel components are located at the central positions of the front and rear ends of the side frame, and a braking caliper is arranged between the upper and lower two groups of the guide wheel components.

[0007] Preferably, the side frame includes two vertical columns arranged front and back, a side cross beam connected between the two columns, and a support column connected between adjacent side cross beams. The support column is located at the center of the front and back ends of the side frame.

[0008] Preferably, the cross section of the column is in a U-shaped structure. The U-shaped grooves of the two columns are arranged oppositely. A fixing plate is arranged at the notch of the U-shaped groove, and a jack is arranged on the fixing plate. The end of the side cross beam passes through the jack and then inserts into the U-shaped groove.

[0009] Preferably, a supporting plate is arranged on the upper end surface of the lower cross beam, and the front and back ends of the conveying component are respectively fixed on the supporting plates at the corresponding ends.

[0010] Preferably, the driving mechanism includes a driving frame connected to the bottoms of two groups of the conveying components, a transmission shaft rotatably installed on the driving frame, transmission wheels arranged at both ends of the transmission shaft, and a driving motor for driving the transmission shaft to rotate. The transmission wheels are connected to the conveying components.

[0011] Preferably, the guide wheel assembly includes a guide wheel seat, two first guide wheels arranged on the front and back sides of the guide wheel seat, and a second guide wheel arranged on the inner side of the guide wheel seat. The first guide wheel and the second guide wheel are distributed in a triangular shape.

[0026] The conveying assembly 2 is fixed on the two lower cross beams 103. The number of the conveying assemblies 2 is at least two to three groups, and they are distributed at intervals left and right. In this embodiment, the number of the conveying assemblies 2 is two groups, and the two groups of conveying assemblies 2 are synchronously driven by a driving mechanism 3.

[0027] A support plate 7 is provided on the upper end surface of the lower cross beam 103, and the front and rear ends of the conveying assembly 2 are respectively fixed on the support plates 7 at the corresponding ends. The width of the support plate 7 is greater than the width of the conveying assembly 2 and the width of the upper end surface of the lower cross beam 103, which improves the supporting capacity of the lower cross beam 103 for the conveying assembly 2.

[0028] The driving mechanism 3 includes a driving frame 301 connected to the bottoms of two groups of conveying assemblies 2, a transmission shaft 302 rotatably installed on the driving frame 301, transmission wheels 304 provided at both ends of the transmission shaft 302, and a driving motor 303 for driving the transmission shaft 302 to rotate. The transmission wheels 304 are connected to the conveying assembly 2. When the conveying assembly 2 is a chain conveyor, the transmission wheels 304 are sprockets, and the chain of the chain conveyor is wound around the transmission wheels 304.

[0029] As Figure 3 shown, the side frame 101 includes two vertical columns 1011 arranged front and rear, a plurality of side cross beams 1012 connected between the two columns 1011, and struts 1013 connected between adjacent side cross beams 1012.

A fixing plate 1014 is provided at the notch of the U-shaped groove 1015, and jacks are provided on the fixing plate 1014. The end of the side cross beam 1012 passes through the jacks and then is inserted into the U-shaped groove 1015. In this embodiment, the fixing plate 1014 is welded to the column 1011, so that the fixing plate 1014 can play a role in limiting and supporting the side cross beam 1012 and improve the overall structural strength of the side frame 101.

[0031] Travel limit switches 6 are respectively provided at the upper and lower ends of the side frame 101, and the two groups of travel limit switches 6 are arranged at the diagonal positions of the side frame 101.

The guide wheel assemblies 4 are located at the central positions of the front and rear ends of the side frame 101, and a brake caliper 5 is provided between the upper and lower two groups of guide wheel assemblies 4. In this embodiment, the distance between the upper and lower two groups of guide wheel assemblies 4 is greater than the width of the lifting frame 1 in the front and rear directions.

[0033] The guide wheel assembly 4 includes a guide wheel seat 401, two first guide wheels 402 provided on the front and rear sides of the guide wheel seat 401, and a second guide wheel 403 provided on the inner side of the guide wheel seat 401. The first guide wheels 402 and the second guide wheel 403 are distributed in a triangular shape, and the track of the hoist is installed between the first guide wheels 402 and the second guide wheel 403 during installation.

[0034] The guide wheel seat 401 is provided with a guide groove 404. The first guide wheel 402 and the second guide wheel 403 are distributed outside the guide groove 404, so that the gap among the two first guide wheels 402 and one second guide wheel 403 corresponds to the guide groove 404 up and down.

[0035] One end of the guide wheel seat 401 away from the side frame 101 is provided with a guard plate 405. The first guide wheel 402 and the second guide wheel 403 are located between the side frame 101 and the guard plate 405. In Figure 4 this case, the guide wheel assembly 4 is installed at the lower end of the side frame 101, and the guard plate 405 is located below the first guide wheel 402 and the second guide wheel 403.
