Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifting trolleys, and particularly relates to a trolley with a lifting function. Background Art
[0002] In the fields of logistics, warehousing, and manufacturing, trolleys, as an important transportation tool, are widely used in the handling, storage, and distribution of goods. However, traditional trolleys often have many limitations in design and function, making it difficult to meet the modern, efficient, and diverse transportation needs.
[0003] Firstly, traditional trolleys usually rely on manual handling when loading and unloading goods, which is not only inefficient but also increases labor costs. Especially when dealing with a large amount of heavy goods, manual loading and unloading is not only time-consuming and laborious but also poses certain safety risks.
[0004] Secondly, traditional trolleys also have deficiencies in cargo separation and protection. Due to the fixed internal space of the carriage and the lack of effective separation measures, different types of goods can only be placed mixed, which not only increases the difficulty of cargo management but also may cause mutual collision and damage between goods. At the same time, for relatively fragile goods, traditional trolleys often cannot provide sufficient protection, increasing the risk of damage during transportation.
[0005] In addition, traditional trolleys also have certain limitations in height adjustment. Since the height of the carriage is fixed and cannot be adjusted according to actual needs, when facing goods of different heights or different storage environments, additional handling or adjustment work is often required, increasing the complexity and cost of transportation.
[0006] Therefore, it is very necessary to invent a trolley with a lifting function. Content of the Utility Model
[0007] The purpose of the utility model is to provide a trolley with a lifting function to solve the problems mentioned in the background art.
[0008] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0009] The utility model relates to a trolley with a lifting function, which comprises a base, universal wheels, a push handle, a cylinder, a carriage, a power supply, a sleeve, a guiding pipe and a limiting frame. A plurality of the universal wheels are fixed to the lower side surface of the base by bolts, and a push handle is fixed to the upper side surface of one end of the base by bolts. A switch group is fixed to the outer side surface of the push handle by bolts. A plurality of the cylinders are fixed to the upper side surface of the base by bolts, and the output ends of the cylinders are fixed to the outer side surface of the upper end of the carriage. The base is in a "U" shape, and the size of the inner groove of the base is the same as that of the lower end of the carriage. A plurality of the sleeves are fixed to the outer side surface of the carriage by welding, and guiding pipes are slidably installed inside the sleeves. The lower ends of the guiding pipes are fixed to the upper side surface of the base by welding. A limiting frame is fixed inside the carriage.
[0010] Furthermore, the carriage comprises a tray, a guardrail, a blocking plate, a rotating column and a conveyor belt. A guardrail is fixed to the upper side surface of the tray by bolts. The guardrail is in a "U" shape, and a blocking plate is slidably installed at the notch position of the guardrail. The upper end of the guardrail is fixed to the output end of the cylinder by bolts, and a plurality of the sleeves are fixed to the outer side surface of the guardrail by welding. A plurality of the rotating columns are rotatably installed on the upper side surface of the tray through support bearings. One end of the outermost rotating column is fixed to the output end of a motor, and the motor is fixed to the outer side surface of the tray by bolts. The outer side surface of the rotating column is wrapped with a conveyor belt. Such a setting facilitates the unloading process and can adjust the height of the goods under the action of the cylinder.
[0011] Furthermore, the limiting frame comprises clamping plates, sponge pads, sliders, guiding columns and stud bolts. The clamping plates are slidably installed inside the guardrail, and sponge pads are fixed to both side surfaces of the clamping plates by bolts. Sliders are fixed to both upper side surfaces of the clamping plates by bolts, and the sliders are respectively slidably installed on the outer side surfaces of the guiding columns. Stud bolts are fixed to the inside of the sliders through thread engagement. The lower ends of the stud bolts are in contact with the guiding columns. Such a setting can form two spaces inside the carriage, so as to facilitate the separated placement of different types of goods. In addition, when transporting relatively fragile goods, the displacement of the goods can be avoided.
[0012] Furthermore, the cylinder and the motor are respectively electrically connected to the switch group through data lines, and the switch group is electrically connected to the power supply through a power cord. During use, the start and stop of the cylinder and the motor can be controlled through the switch group.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. When the carriage of the present utility model is in use, the goods to be transported can be placed on the conveyor belt, and the goods are carried by the supporting forces of the conveyor belt and the rotating column. When unloading is required, the blocking plate can be removed from the guardrail, and then the carriage is driven down by the cylinder so that the pallet contacts the ground. Then, through the cooperation of the motor, the rotating column and the conveyor belt, the goods are moved out at the notch position of the guardrail. In addition, the carriage can be driven up by the cylinder to adjust the height of the goods.
[0015] 2. When the limiting frame of the present utility model is in use, the clamping plate can form two spaces inside the carriage, so as to facilitate the separate placement of different types of goods. When transporting large goods, the stud can be loosened, and then the clamping plate is moved to one end of the carriage to avoid the influence of the clamping plate on the storage of the goods. In addition, when transporting relatively fragile goods, the slider can be slid so that the sponge pad on the clamping plate contacts the goods inside the goods carriage, and then the stud is rotated so that the stud squeezes the guiding column to prevent the goods from moving inside the carriage.

[0026] As Figure 2As shown in the figure, the carriage 5 includes a pallet 51, a guardrail 52, a baffle 53, a rotating column 54 and a conveyor belt 55. The upper side of the pallet 51 is fixed with a guardrail 52 by bolts. The guardrail 52 is in the shape of a "U", and a baffle 53 is slidably installed at the notch position of the guardrail 52. The upper end of the guardrail 52 is fixed to the output end of the cylinder 4 by bolts, and several sleeves 7 are fixed to the outer side of the guardrail 52 by welding.
