Description

Technical Field

[0001] The utility model relates to the field of cold chain warehousing, and in particular to a loading and unloading device for cold chain warehousing. Background Art

[0002] Cold chain warehousing refers to a system that ensures that perishable products are kept within a safe temperature range during transportation, storage and distribution through strict temperature control and monitoring throughout the supply chain, mainly for the storage of food and medicine. This warehousing system usually involves specially designed facilities and equipment, including cold storage, freezer, cold chain transportation vehicles, etc., to ensure the quality, freshness and safety of the products.

[0003] Cold chain warehousing involves temperature-controlled products. Existing goods are usually loaded and unloaded by operators onto carts. The labor-intensive process of moving goods back and forth is relatively complicated, and the loading and unloading efficiency is low, which increases temperature loss. Utility Model Content

[0004] The purpose of the present utility model is to provide a loading and unloading device for cold chain warehousing in order to solve the above-mentioned problems, as described below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a loading and unloading device for cold chain warehousing, comprising a base bar, a bottom surface of the base bar being provided with a bottom wheel, a plurality of slide grooves penetrating the base bar, the slide grooves being inclined, and a plurality of the slide grooves being distributed along the length direction of the base bar, a sliding block being slidably connected in the slide groove, the outer end of the sliding block passing through the base bar and being connected to a support seat, and a thrust component for pushing all the sliding blocks to slide synchronously in the slide grooves being installed on the base bar.

[0007] It is further explained that there are two basic bars, and the two basic bars are connected by a connecting rod.

[0008] It is further described that the connecting rod is close to one end of the base bar, and a pull rod is provided on the outside of the connecting rod.

[0009] It is further described that the thrust assembly includes a base plate, a push plate corresponding to the slide groove is provided on the surface of the base plate, and an electric push rod is provided on the base bar for pushing the base plate or the push plate to move along the length direction of the base bar.

[0010] It is further described that the cross section of the support seat is rectangular.

[0011] It is further described that the push plates are provided on both sides of the base strip.

[0012] It is further described that a horizontally extending guide groove is provided on the outer side of the base strip, and the push plate faces the side wall of the base strip and is in clearance fit with the guide groove.

[0013] It is further described that a spring is provided in the slide groove to push the slide block to slide toward the push plate.

[0014] The beneficial effects are:

[0015] All the sliding blocks are pushed to move by the thrust assembly. After the sliding blocks move toward the high end of the chute, the cargo is lifted up by multiple support seats, which is convenient for carrying the cargo. After the sliding blocks move toward the low end of the chute, the support seats are away from the cargo, realizing the unloading of the cargo. The use is simpler and more flexible, improving the cargo loading and unloading efficiency and reducing the temperature loss.

[0016] In a preferred embodiment, the telescopic energy of the electric push rod is used to push the push plate or the bottom plate to move, thereby pushing all the support seats to move synchronously, which has a good supporting effect on the cargo box, and is more flexible to use by cooperating with the spring to assist the sliding block in resetting.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] First embodiment:

[0025] See also Figure 1-Figure 3 As shown, the utility model provides a loading and unloading device for cold chain storage, including a base bar 1, a bottom wheel 102 is provided on the bottom surface of the base bar 1 to assist the base bar 1 in moving, a plurality of slide grooves 105 are penetrated on the base bar 1, the slide grooves 105 penetrate the width side walls of the base bar 1, the slide grooves 105 are inclined, and the plurality of slide grooves 105 are distributed along the length direction of the base bar 1, a sliding block 2 is slidably connected in the slide groove 105, the outer end of the sliding block 2 passes through the base bar 1, and is connected to a support seat 201, and a device for pushing all the sliding blocks 2 to slide is installed on the base bar 1 The thrust assembly 3 slides synchronously in the groove 105. During the use of the device, all the sliding blocks 2 are pushed to move by the thrust assembly 3. When the sliding block 2 moves toward the high end of the slide groove 105, the support seat 201 rises accordingly. The support seat 201 can lift the goods, and the bottom wheel 102 is used to assist the movement of the base bar 1, thereby assisting the loading and unloading operations of the goods. The operation is simpler and more convenient, the use is very flexible, and the use effect is good. After the sliding block 2 moves toward the low end of the slide groove 105, the support seat 201 is away from the goods, so that the placement and unloading of the goods are realized.

[0026] The second embodiment is different from the first embodiment in that:

The connecting rod 101 is close to one end of the basic bar 1, and a pulling rod 103 is provided on the outside of the connecting rod 101. The connecting rod 101 can be pulled by the pulling rod 103, thereby pulling the two basic bars 1 to move, so that the basic bars 1 can move smoothly.

[0028] The third embodiment is different from the first embodiment in that:

[0029] In the structure of the thrust assembly 3, the thrust assembly 3 includes a bottom plate 301, a push plate 302 corresponding to the slide groove 105 is provided on the surface of the bottom plate 301, and an electric push rod 303 is provided on the base bar 1 for pushing the bottom plate 301 or the push plate 302 to move along the length direction of the base bar 1.

[0030] The support seat 201 has a rectangular cross section, and its vertical side wall is in contact with the push plate 302. When the push plate 302 moves horizontally, the push plate 302 can push the support seat 201, so that the sliding block 2 slides inside the slide groove 105, and guides the support seat 201 so that the support seat 201 can slide horizontally upward, and can lift the freezer or refrigerator in the cold chain warehouse through the top surface of the support seat 201, and move with the bottom wheel 102 auxiliary device;

[0031] Push plates 302 are provided on both sides of the base bar 1, which can enable the push plates 302 to slide smoothly, thereby pushing the support seats 201 on both sides of the sliding block 2 to slide smoothly. Furthermore, a horizontally extending guide groove 104 is provided on the outer side of the base bar 1. The push plate 302 faces the side wall of the base bar 1 and is gap-matched with the guide groove 104.
