The first guide roller 102a and the second guide roller 102b are respectively arranged on the top and bottom side walls of the opposite surfaces of the two side plates 101b, and the first guide roller 102a and the second guide roller 102b are provided with a plurality of groups of guide wheels S. The connecting rope 102c cooperates and rolls on the corresponding guide wheels S on the first guide roller 102a and the second guide roller 102b.

[0040] The pallet assembly 103 includes a first pallet component 103a and a second pallet component 103b, which have the same structure and are arranged at different heights on both sides of the side plate 101b; the first pallet component 103a and the second pallet component 103b are movable between the two limit plates 101c-3 at the upper and lower ends.

[0041] The first support plate member 103a includes a support plate 103a-1, a fixed tube 103a-2 and a sliding tube 103a-3 arranged on the side wall of the support plate 103a-1, and a support block 103a-4 arranged below the connecting end of the support plate 103a-1; the fixed tube 103a-2 can be fixedly connected to the connecting rope 102c; the sliding tube 103a-3 can be slidably mounted on the limiting rod 101c-2.

[0042] Compared with the first embodiment, the bracket 101 further comprises a rectangular bottom plate 101a, which has a groove cavity on the plate surface, the two sides of the plate surface are higher than the middle part, and the side wall of the bottom plate surface is provided with universal wheels for easy movement; the side plates 101b are perpendicular to the plate surface of the bottom plate 101a, symmetrically distributed on the two sides of the bottom plate 101a, and the height of the side plates 101b is relatively high, so as to be suitable for unloading the plates from the transport vehicle full of plates, and the tops of the two side plates 101b can be connected as a whole. The two side plates 101b are connected and reinforced by the limiter 101c.

[0043] Specifically, the limiting member 101c includes a fixing plate 101c-1 and a limiting rod 101c-2, wherein the fixing plate 101c-1 has a group of two, which are parallel to each other, and the two ends of the fixing plate 101c-1 are respectively fixed on the side walls of the side plates 101b on both sides, and the two fixing plates 101c-1 are respectively located at the upper and lower ends of the side plates 101b, and between the two fixing plates 101c-1, multiple groups of limiting rods 101c-2 are fixed in two rows in parallel perpendicular to the plate surface.

[0044] The limiting member 101c also has a limiting plate 101c-3, which has two groups of four plates, each group is distributed on one side of the fixed plate 101c-1, and two are symmetrically distributed on both sides of the opposite surfaces of the two fixed plates 101c-1. The spacing between them is smaller than the spacing between the two fixed plates 101c-1, and is used to limit the range of movement of the pallet assembly 103.

[0045] Furthermore, the guide assembly 102 has two identical guide rollers, namely, a first guide roller 102a and a second guide roller 102b. The structure of the first guide roller 102a is used as an example for explanation. A plurality of guide wheels S are distributed on the roller body of the first guide roller 102a. The circumferential side walls of the guide wheels S have grooves, which can be used to limit the connection rope 102c to slide therein. The two guide rollers are distributed on the side walls of the two side plates 101b on the opposite sides and are located at the upper and lower ends of the side plates 101b, which can straighten the connection rope 102c. This structure can keep the two sides of the guide roller in an up-and-down reciprocating motion.

[0046] The pallet assembly 103 is composed of two pallet parts with the same structure, namely a first pallet part 103a and a second pallet part 103b. The structure of the first pallet part 103a is used as a specific description, wherein it includes a pallet 103a-1 main body, which is a rectangular plate-shaped structure with a connecting end. The side wall of the connecting end is provided with a fixed tube 103a-2 and a sliding tube 103a-3, wherein the fixed tube 103a-2 is fixed to the connecting rope 102c as a whole, and the sliding tube 103a-3 is sleeved and slid on the limit rod 102c-2. It should be noted that the fixed tube 103a-2 and the sliding tube 103a-3 are each provided with multiple groups, and the number of each is equal to the number of the connecting rope 102c and the limit rod 102c-2, and corresponds one to one.

[0047] A support block 103a-4 is provided at the bottom of the plate body at the connection end of the support plate 103a-1. The support block 103a-4 is tilted and connected to the sliding tube 103a-3 to improve the support strength of the support plate 103a-1.

[0048] The remaining structures are the same as those of Example 1.

[0049] Example 3

[0050] Reference Figure 1 , Figure 4 and Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the buffer assembly 201 includes a first buffer box 201a and a second buffer box 201b symmetrically distributed on both sides of the side plate 101b, and a connecting pipe 201c connecting the two. The first buffer box 201a and the second buffer box 201b have the same structure; the number of the connecting pipes 201c is not less than two, and a one-way valve D is provided in the connecting pipe 201c.

[0051] The first buffer box 201a has a hydraulic buffer bag 201a-1 in it, and the hydraulic buffer bag 201a-1 is connected with the connecting pipe 201c; an extrusion groove 201a-2 is also opened on the top side wall of the first buffer box 201a.

[0052] The shock-absorbing member 202 includes a contact plate 202a that slides in the extrusion groove 201a-2, a connecting rod 202b arranged below the contact plate 202a, a shock-absorbing spring 202c mounted on the connecting rod 202b, and an extrusion plate 202d that passes through the extrusion groove 201a-2 and is in extrusion contact with the hydraulic buffer bag 201a-1.

[0053] Compared with Example 2, the buffer assembly 201 is further divided into two buffer boxes, namely the first buffer box 201a and the second buffer box 201b, which have the same structure, are installed on the top plate surface of the bottom plate 101a, and are symmetrically distributed on both sides of the two side plates 101b, and the sides facing each other are connected through the connecting pipe 201c. Now only the structure of the first buffer box 201a is specifically described.

[0054] Specifically, the first buffer box 201a has an extrusion groove 201a-2 on its surface, and the box is hollow and contains a hydraulic buffer pack 201a-1. The hydraulic buffer pack 201a-1 can be understood as a flexible packaging bag containing a hydraulic solution, and the hydraulic solution can be hydraulic oil or an aqueous solution. The hydraulic buffer pack 201a-1 in the first buffer box 201a is connected to the hydraulic buffer pack in the second buffer box 201b through a connecting pipe 201c. However, it should be noted that the number of connecting pipes 201c between the first buffer box 201a and the second buffer box 201b is no less than two, and a one-way valve D is also installed in the pipe, that is, the first buffer box 201a is connected to the second buffer box 201b in one direction, and the second buffer box 201b is connected to the first buffer box 201a in one direction. When the hydraulic buffer pack 201a-1 in any buffer box is squeezed, the hydraulic solution inside it will be pushed to flow to the hydraulic buffer pack 201a-1 in the other buffer box in one direction.

[0055] The shock absorbing member 202 is in an I-shaped structure, such as Figure 6 As shown in the figure, the top is a contact plate 202a, which is convenient for contacting with the bottom of the support plate 103a-1, the middle is a connecting rod 202b, and the bottom is an extrusion plate 202d. A shock-absorbing spring 202c is sleeved on the connecting rod 202b, and the lower end of the shock-absorbing spring 202c is connected to the bottom of the groove cavity of the extrusion groove 201a-2, and the extrusion plate 202d passes through the bottom of the extrusion groove 201a-2 and contacts with the hydraulic buffer bag 201a-1, which is used to extrude the hydraulic buffer bag 201a-1 and release pressure.

[0056] The remaining structure is the same as that of Example 2.

[0057] Combined with the attached drawings Figure 1 to Figure 7 As shown in, during the use of the loading and unloading conveying device, the device is moved to the target area of ​​the plates to be loaded and unloaded through the universal wheels at the bottom, and the pallet 103a-1 of the first pallet member 103a is moved to the highest point. Correspondingly, the pallet in the second pallet member 103b is in the lowest position under the action of the connecting rope 102c; the plates to be loaded and unloaded are placed on the plate surface of the pallet 103a-1 of the first pallet member 103a. At this time, the pallet 103a-1 of the first pallet member 103a is accelerated downward from static under the action of the gravity of the plates, and the connecting rope 102c is pulled, so that the pallet in the second pallet member 103b is accelerated upward from static, consuming part of the gravitational potential energy of the plates.

[0058] When the bottom of the support plate 103a-1 of the first support plate member 103a gradually contacts with the contact plate 202a, the contact plate 202a is squeezed to move downward. At this time, the shock-absorbing spring 202c will be squeezed first, and the pressure keeping the support plate 103a-1 in contact with the contact plate 202a will gradually increase; then the squeezing plate 202d will gradually squeeze the hydraulic buffer bag 201a-1, so that the hydraulic pressure in the bag can gradually flow into the hydraulic buffer bag 201a-1 on the other side through the connecting pipe 201c, and the kinetic energy of the plate and the support plate 103a-1 is converted to open the one-way valve D, promoting the flow of the hydraulic solution, and finally making the plate and the support plate 103a-1 gradually slow down and be at the lowest point; at the same time, the hydraulic buffer bag 201a-1 on the other side expands due to the increase of the hydraulic solution, propping up the shock-absorbing member 202, and the support plate in the second support plate member 103b is at the highest point.

[0059] At this time, the plate to be loaded and unloaded is placed on the pallet in the second pallet member 103b, and the above-mentioned action process is repeated to continuously load and unload the plate.

[0060] The device has a simple structure, significant loading and unloading effect, high practicability, and can greatly improve the efficiency of plate loading and unloading.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
