Description
Technical Field
[0001] The utility model relates to a logistics loading appliance, in particular to a logistics loading appliance for a four-way electric power-assisted steering column assembly, belonging to the technical field of automotive parts manufacturing. Background Art
[0002] According to the applicant's understanding, the original packing method: the completed and off-line four-way electric power-assisted steering column assembly in the parts manufacturing factory is placed in a carton package composed of a paper inner lining and a paper outer periphery, and is transported to the main engine factory.
[0003] The deficiencies of this packing form are as follows:
[0004] 1. The strength of the carton package is not as good as that of an iron appliance, and it is easy to be damaged during transportation and loading and unloading, resulting in appearance complaints and even affecting the internal product quality, causing greater losses. (The price of one assembly is 3 times that of a carton, and there are 24 assemblies per box on average)
[0005] 2. After the carton package is packed, it is not easy to carry out the selection work. In the quality management of the main engine factory, there will be a quality control operation of rummaging through the boxes for selection. The carton is not convenient to observe from the outside, and it needs to be taken out of the box one by one. As a result, the disposable paper inner lining is easy to be damaged and cannot be reused. At the same time, it wastes the labor of taking and putting one by one.
[0006] 3. In large-scale supply, the carton cannot be recycled. When the supply volume exceeds the critical point, the cost sharing of choosing the carton package is higher than that of the recyclable logistics loading appliance. Content of the Utility Model

Detailed implementation manners
[0029] A rack for a four-way electric power-assisted steering column assembly provided in this embodiment has a structure as shown in the figure, and includes a column frame, a support mechanism, a towing and moving mechanism, a fixed protection device, an angle adjustment device, a towing connection device, and a universal roller device.
[0030] Among them, the column frame is a rectangular frame, including a plurality of columns 4, horizontal support square pipes 1, and vertical support square pipes 6 that are perpendicularly connected to each other. The columns are symmetrically arranged on both sides in the height direction of the rectangular frame, while the horizontal support square pipes and the vertical support square pipes are respectively arranged in the length direction and the width direction of the rectangular frame, and are welded to the columns to form a whole.
[0031] At the same time, the top of the column is sealed by a top cover 5, and a bottom support is installed at the bottom for double-layer stacking. Four groups of universal wheels 14 are installed at the bottom, which can conveniently move the rack.
[0032] The support mechanism has four layers and is installed in the column frame at equal intervals. At the same time, below the support mechanism of the bottom layer, that is, at one-third of the column frame from bottom to top, a rectangular frame for support is also provided.
[0033] The support mechanism is composed of vertical square pipes, horizontal square pipes, and support square pipes. Among them, the vertical square pipes are symmetrically arranged in the width direction of the column frame, and the horizontal square pipes and the square columns are fixed between the two vertical square pipes. From front to back, they are the fourth square pipe, the third square pipe, the second square pipe, the vertical support square pipe, the first square pipe, and the horizontal support square pipe. The support square pipes are installed behind the second square pipe and the first square pipe, and play a role in fixing and supporting the support frame.
[0034] The fixed protection device is composed of two parts, namely a fixing mechanism for placing the electric power-assisted steering column assembly and a protection mechanism for preventing the electric power-assisted steering column assembly from being knocked.
[0035] The fixing mechanism consists of an intermediate shaft limiting block installed on the fourth square tube, a housing fixing limiting block installed on the third square tube, and an upper shaft fixing limiting block installed on the second square tube. The structural dimensions of the fixing limiting liner are the same as those of the part of the pipe string assembly, and both are composed of a base groove. In this embodiment, the number of grooves is five, which is used to fix and prevent displacement when placing the electric power steering column assembly.
[0036] The protection mechanism consists of a front protection pad, a rear protection pad, and a side protection pad. The front protection pad is installed on the third square tube, the rear protection pad is installed on the fourth square tube, and the side protection pad is installed on the inner side of the square tube. Through the setting of these protection pads, the buffering effect can be improved, the electric power steering column assembly can be protected, and damage caused by collision can be prevented.
[0037] The angle adjustment device consists of a cylinder, a direction bolt, a rotating sleeve, and a tension rod. The cylinder is arranged along the length direction of one side square tube, and the cylinders on each layer of the support mechanism are cross-distributed on the left and right sides of the square tube. Such an arrangement can better maintain the balance of the overall structure. The top end of the cylinder is fixed to the column through a direction bolt and a nut, and the output end is connected to the tension rod. The end of the tension rod is fixed to the middle position between the first square tube and the second square tube of the support mechanism square tube through a direction bolt and a nut. Rotation holes are provided at both ends of the square column, and rotation holes are also provided at the corresponding positions of the column. The rotating sleeve is installed in the rotation holes to connect the support mechanism and the column frame, enabling the square column to rotate relative to the rotation holes.
[0038] The towing and moving mechanism consists of a towing connection device and a universal roller device.
[0039] The towing connection device consists of a tow hook and a hook, which is used to enable the overall column frame to transmit traction under power traction so as to achieve towing, and can realize the movement of multiple racks arranged as a whole.
[0040] The universal roller device consists of a universal wheel, a support foot, and a spring bolt, which is used to enable the overall column frame to achieve displacement in various directions under power traction and directional towing.
[0041] The working process of this embodiment is as follows:
[0042] Step 1, as Figure 1 shown, open the support part inside the column frame. Starting from the top first layer of the support mechanism, first grasp the fourth square tube and make a fan-shaped movement upward, and sequentially open the first, second, third, and fourth layer support mechanisms. The fifth layer support mechanism remains stationary.
[0043] Step 2: Pick up the four-way electric power steering column assembly and place it into the fifth-layer support mechanism from left to right in sequence. Place the housing in the middle of the four-way electric power steering column assembly into the groove of the fixed housing limit lining, place the steering shaft at the head into the corresponding groove of the fixed upper shaft limit lining, and place the intermediate shaft at the tail into the groove of the fixed intermediate shaft limit lining.
[0044] Step 3: After completing Step 2, hold the fourth square tube of the fourth-layer support mechanism and move it downward in a fan shape until the bottom of the support tube touches the fifth-layer support mechanism, and fill the four-way electric power steering column assembly according to the placement method of the fifth-layer support mechanism.
[0045] Step 4: Arrange them in sequence according to the foregoing steps until all four layers are placed completely, and clip the corresponding paper label onto the paper clip on the baffle. Connect it to other racks or trailers through the tow hook and the hook.
[0046] In addition to the above embodiments, the present utility model may also have other embodiments. All technical solutions using equivalent replacements or equivalent transformation forms fall within the protection scope required by the present utility model.
