Description
Technical Field
[0001] This utility model relates to the technical field of vehicle-mounted hoisting equipment, and in particular to a telescopic hoisting structure and a vehicle-mounted cargo compartment for use in a vehicle-mounted cargo compartment. Background Technology
[0002] Vehicle-mounted containers and van bodies typically have large storage spaces, especially military vehicle-mounted containers, which often carry a lot of high-value equipment. Depending on actual usage, there is a significant demand for loading and unloading this equipment. The equipment inside military vehicle-mounted containers is usually characterized by high value, large size, heavy weight, and a large number of electronic components. Therefore, a mechanism is needed to reliably, safely, conveniently, and quickly perform loading and unloading operations within the vehicle-mounted container.
[0003] Currently, the most common lifting mechanisms on the market are electric or manual hoists. These utilize a triangular cantilever folding mechanism to suspend the hoist outside the container / cargo box for lifting equipment / goods. Simultaneously, the rotation axis between the triangular cantilever and the container / cargo box frame allows for suspended movement of the equipment / goods. However, this method presents challenges such as difficulty in lifting heavy loads, difficulty in achieving large suspended displacements of equipment / goods, and significant swaying of the suspended equipment / goods. Mechanisms that add hydraulic tailgates to the rear of the container / cargo box suffer from drawbacks such as complex mechanisms, difficult maintenance, high cost, poor environmental adaptability, and significant space occupation, sacrificing usable space inside the container / cargo box. Furthermore, in practical applications, the rear cannot often be opened. Utility Model Content

[0021] The above-mentioned technical solution of this utility model has the following advantages:
[0022] This utility model provides a telescopic hoisting structure for use in a vehicle-mounted cargo hold, comprising two first slide rails, a hoisting adjustment unit, and an electric hoist. The two first slide rails are arranged parallel and spaced apart on the top of the cargo hold. Each first slide rail includes a first track and a first slider. The first track is fixedly installed on the cargo hold, and the first slider can slide along the first track. The hoisting adjustment unit includes two second slide rails arranged in the same direction as the two first slide rails. Each second slide rail includes a second track and a second slider.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0060] Example 1
[0061] like Figures 1-5 As shown, the telescopic hoisting structure 1 for use in a vehicle cargo compartment provided in this embodiment of the present invention includes two first slide rails 11, a hoisting adjustment part and an electric hoist 14.
[0062] In use, the two first slide rails 11 are arranged in parallel at intervals on the top of the cargo compartment (see...). Figures 11-14 The first slide rail 11 includes a first track 111 and a first slider 112. The first track 111 is fixedly installed on the chamber body 2, and the first slider 112 can slide along the first track 111.
[0063] See Figure 1 , Figure 2 and Figure 8 As shown, the hoisting adjustment unit includes two second slide rails 12, which are arranged in the same direction as the two first slide rails 11. Each second slide rail 12 includes a second track 121 and a second slider 122. The second tracks 121 of the two second slide rails 12 are respectively installed on the inner side of the two first sliders 112, so that the two second tracks 121 are arranged relatively spaced apart and can slide along the first track 111 with the first sliders 112.
[0064] The electric hoist 14 is positioned between two second slide rails 12 and connected to two second sliders 122, and can slide along the second track 121 with the second sliders 122.
[0065] In use, the first slider 112 slides relative to the first rail 111, driving the electric hoist 14 to the lifting position. After the goods are lifted, it moves in the opposite direction to load the goods into the warehouse. The use of two parallel and spaced first rails 11 enables stable lifting, and the electric hoist 14 occupies little space. In addition, the electric hoist 14 is connected to the first rail 11 through a lifting adjustment part, allowing the electric hoist 14 to move with the first slider 112. Under the action of the lifting adjustment part, when the first rail 11 does not slide, the electric hoist can slide independently with the second rail 12. On the one hand, it can increase the stroke of the electric hoist 14 to a certain extent when needed (see...). Figure 4 When no increase in stroke is required, the electric hoist 14 can remain in a more suitable lifting position (see...). Figure 2 and Figure 3 This design balances the requirements for travel distance and lifting stability, while also allowing the electric hoist 14 to be retracted into the compartment a certain distance when retracted (see [reference]). Figure 1 This allows the cargo door to close properly and prevents it from being struck during transit, while also preventing accidental injury to personnel opening the door.
[0066] To further refine the position adjustment of the electric hoist 14 and better meet lifting requirements, in one example, see... Figure 1 , Figure 3 and Figure 7 As shown, the second track 121 is slidably mounted on the first slider 112 via an adapter 15. The adapter 15 includes an adapter seat 151 and a third slider 152. The adapter seat 151 is fixedly mounted on the first slider 112, and the third slider 152 is fixedly mounted on the adapter seat 151. One side of the second track 121 is slidably connected to the third slider 152, and the other side is slidably connected to the second slider 122. That is, the second track 121 is a shared track for the second slider 122 and the third slider 152. This simplifies the structure and, by setting the adapter 15, reduces the structural requirements of the first slide rail 11. For example, a commercially available linear guide rail can be purchased directly as the first slide rail, and the second slide rail 12 can be mounted on the purchased linear guide rail via the adapter 15.
[0067] See Figure 7 and Figure 8 As shown, in one example, the cross-section of the second track 121 is I-shaped, with a groove on one side engaging with the second slider 122 and a groove on the other side engaging with the third slider 152.
[0068] See Figure 7 , Figure 8 and Figure 10 As shown, in one example, the adapter 151 includes a first mounting plate and a second mounting plate, which are vertically connected and have an L-shaped cross-section. The first mounting plate is fitted onto the surface of the first slider 112, and the second mounting plate is located inside the first slide rail 11 for mounting the third slider 152, thereby realizing the connection and installation of the second track 121.
[0069] To facilitate the assembly and disassembly of the electric hoist 14 and reduce structural modifications to the second slide rail 12, in one example, see [reference needed]. Figure 1 , Figure 2 and Figure 9 As shown, the electric hoist 14 is fixedly connected to two second sliders 122 via a mounting base 13, and the electric hoist 14 is detachably mounted on the mounting base 13. Preferably, the cross-section of the mounting base 13 is U-shaped, and the electric hoist 14 is installed inside the U-shape, further reducing the space occupied. When disassembling, assembling, or replacing for maintenance, the mounting base 13 can be removed or replaced.
[0070] In order to minimize weight and facilitate the fixing of the electric hoist 14, in one example, the mounting base 13 is provided with a cutout.
[0071] Similarly, in order to minimize weight and facilitate the fixing of the third slider 152 and its fixed connection with the first slider 112, in one example, see... Figure 10 As shown, the adapter 151 has a cutout.
[0072] In this embodiment, see Figure 2 and Figure 6 As shown, the first slider 112 slides relative to the first track 111 via the ball screw pair 113. The first track 11 also includes a motor 114 for providing power to the ball screw pair 113.
[0073] Preferably, in this embodiment, limiting devices are provided between the first slide rail 11, the second slide rail 12, and the third slider 152 and the second track 121 to improve safety. The limiting devices can be electrical limiting devices, mechanical limiting devices, or a combination of both, and are not limited here. The specific structure can use existing technology, and will not be described in detail here.
[0074] Furthermore, existing technologies can be used to control and brake the slide rail. For example, the electric hoist can be slid by pulling the brake cable on the controller to release the locked state of the slide rail, and the slide rail will be automatically locked when the brake cable is released. This will not be elaborated further here.
[0075] Example 2
[0076] like Figure 11 and Figure 12As shown, the vehicle-mounted cargo hold provided in this embodiment two includes a cargo hold body 2 and any of the telescopic lifting structures 1 in embodiment one. This vehicle-mounted cargo hold can stably lift goods, and the telescopic lifting structure 1 can be completely retracted into the cargo hold, which is conducive to its widespread use.
[0077] The telescopic hoisting structure 1 only requires the first rail 111 to be fixed to the top of the silo body 2 to achieve hoisting. Preferably, the top outer side of the silo body 2 is provided with an installation groove 21, and the bottom of the installation groove 21 is provided with a sliding channel 211 arranged along the sliding direction of the first slide rail 11. The two first rails 111 are installed at the bottom of the installation groove 21 and are located on both sides of the sliding channel 211. The hook of the electric hoist 14 extends into the silo body 2 through the sliding channel 211 to meet the hoisting and movement requirements of the electric hoist 14, and can realize the hoisting of goods from the loading and unloading port 23 into the silo body 2.
[0078] See Figure 13 As shown, the groove opening of the mounting slot 21 is provided with a removable cover plate 22, which can cover and protect the telescopic hoisting structure 1.
[0079] See Figure 14 As shown, a vehicle-mounted cargo compartment with the loading and unloading port 23 located on the side is provided. Due to the telescopic hoisting structure 1 of this utility model, the electric hoist can be completely retracted into the compartment. Therefore, the telescopic hoisting structure 1 can be applied to situations where the loading and unloading port 23 is on any side of the compartment.
[0080] It should be noted that the warehouse body can be a vehicle-mounted modular cabin, the body of a van, or a container, etc.
[0081] Any aspects not described in detail in this embodiment are common knowledge or existing technology in the field.
[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution. In the absence of any conflict between the solutions, the various technical features mentioned in each embodiment can be combined in any way to form other implementation methods that can be understood by those skilled in the art.
[0083] Furthermore, without departing from the scope of this utility model, modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, shall not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
