An adjustable load-bearing transfer vehicle

Abstract

This application discloses an adjustable load-bearing transfer cart, which includes a planar rectangular transfer frame with rollers at its bottom corners. The transfer frame is composed of tubular bodies connected at both the transverse and longitudinal ends, and is divided into a fixed section and an adjustable section. The transverse tubular end of the adjustable section has an adjusting tube that can pass through the transverse tubular body of the fixed section. This load-bearing transfer cart is made of square tubing, which, compared to the currently used flat-panel structure, effectively improves the load-bearing capacity of the cart body, thus avoiding the problem of the cart body denting during long-term transfer, leading to unstable product placement. The fixed and adjustable sections allow for adjustment of the cart's load-bearing area, adapting to the transfer and placement of products of different sizes, solving the problem of commonly used small carts having a fixed load-bearing area, which cannot stably place excessively large products and is prone to tipping over during transfer.

Description

Technical Field

[0001] This application relates to the field of product transfer technology, and in particular to an adjustable load-bearing transfer vehicle. Background Technology

[0002] Cargo handling trolleys are indispensable equipment in logistics, warehousing, and manufacturing industries. They are primarily used to improve cargo handling efficiency, reduce labor intensity, and ensure cargo safety. Common types of trolleys include manual / hydraulic pallet trolleys, electric pallet trolleys, electric stackers, magnetic strip-guided AGVs, and rail-mounted trolleys. They are suitable for material transport on production lines, such as in the automotive manufacturing and electronics assembly industries.

[0003] Currently, common and easy-to-use transport carts such as Figure 1 The structure shown is widely used in product transportation in enterprises due to its simple structure and low purchase cost. It mainly consists of a flatbed and wheels at its bottom. However, during long-term transport of heavy objects, the flatbed, which typically only has four wheels at the bottom, leaves the portion without wheels suspended in the air. Due to the continuous force of the product's weight, the flatbed (which is usually relatively thin)... Figure 1 (As indicated by the dimensions marked by the middle arrow) The surface will exhibit varying degrees of concavity. Figure 2 As shown in the diagram, the surface of the plate is uneven, which can cause instability and tipping during subsequent product transfer. In addition, the plane area of ​​the transfer trolley is fixed, and when transferring larger products, the products may extend beyond the outside of the plate, which can also cause them to fall during the transfer process. Utility Model Content

[0004] To address the aforementioned problems, this application aims to provide an adjustable load-bearing transfer cart, which can effectively improve the load-bearing capacity of the cart body, thereby avoiding the problem of the product being unstable and unable to be placed during long-term transfer due to the cart body sinking; at the same time, by adjusting, it solves the problem that the commonly used carts have a fixed load-bearing area, which cannot stably place excessively large products and are prone to tipping over during transfer.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an adjustable load-bearing transfer vehicle, the transfer vehicle including a transfer frame with a planar rectangular structure, with rollers provided at the bottom corners, the transfer frame being composed of a tube body with the transverse and longitudinal ends connected, the transfer frame being divided into a fixed section and an adjustable section, the transverse tube end of the adjustable section being provided with an adjusting tube that can be inserted into the transverse tube body of the fixed section.

[0006] Preferably, the pipe body of the fixed section is also provided with a locking bolt that can abut against the side wall of the adjusting pipe; and a drive handle is also hinged to the inner side of the fixed section near the longitudinal pipe body.

[0007] Preferably, a transfer plate that can be tilted and supported on the ground is hinged to the longitudinal tube at the front of the adjustment section, and the transfer plate can be flipped to be flush with the surface of the adjustment section.

[0008] Preferably, the sidewalls of the adjusting tubes located on both longitudinal sides are configured as inclined structures that contact the locking bolts in the opposite transverse direction.

[0009] The beneficial effects of this application are: the load-bearing transport vehicle is made of square tubing, which can effectively improve the load-bearing capacity of the vehicle body compared with the currently used flat structure, thereby avoiding the problem of the product being unable to be placed and transferred stably due to the vehicle body sinking during long-term transport.

[0010] The transfer vehicle is equipped with fixed and adjustable sections, which can adjust the load-bearing area of ​​the vehicle body to adapt to the transfer and placement of products of different sizes. This solves the problem that the commonly used small vehicles have a fixed load-bearing area and cannot stably place excessively large products, making them prone to tipping over during transfer.

[0011] The set-up transfer plate can quickly transfer products onto the vehicle body, which saves effort compared to lifting the products directly, improves product transfer efficiency, and reduces physical burden.

[0012] The inclined structure of the adjusting tubes on both sides can effectively overcome the relative slippage of the locking bolts, ensure the stability of product transfer, and avoid wear on the bottom surface of the product caused by the movement of the adjusting section.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] See attached document Figures 3-14 The adjustable load-bearing transfer vehicle shown includes a planar rectangular transfer frame 1, with rollers 2 (preferably lockable casters) at each of its bottom corners. The transfer frame 1 is composed of tubular bodies 3 (which can be square or round tubes; this application uses square tubes with a certain wall thickness) connected at their transverse and longitudinal ends. The casters typically have mounting top plates 21, which are simultaneously welded and fixed to the transverse and longitudinal tubular bodies (e.g., ...). Figure 4 As shown, this design enhances the stability of the welded transverse and longitudinal tubes. The load-bearing transport vehicle of this application is made of square tubing, which, compared to the currently used flat-panel structure, effectively improves the load-bearing capacity of the vehicle body, thereby avoiding the problem of product instability during long-term transport due to dents in the vehicle body.

[0030] In order to make appropriate adjustments according to the size of the product, such as Figure 3-6 As shown, the transfer frame 1 is divided into a fixed section 11 and an adjustable section 12, specifically, as follows: Figure 5-6As shown in the structure, the end of the transverse tube 3 of the adjusting section 12 is provided with an adjusting pipe 31 that can pass through the transverse tube 3 of the fixed section 11. That is, the adjusting pipe 31 that can pass through the transverse tube 3 of the fixed section 11 is welded to the end of the transverse tube of the adjusting section 12. By adjusting the insertion depth of the adjusting pipe 31 in the transverse tube of the fixed section 11, the distance between the fixed section 11 and the adjusting section 12 can be adjusted, thereby adjusting the carrying area of ​​the transfer vehicle body to adapt to the transfer and placement of products of different sizes. This solves the problem that the carrying area of ​​commonly used trolleys is fixed and cannot stably place excessively large products, and they are prone to tipping over during transfer.

[0031] To lock the position after adjusting the fixed section 11 and the adjusting section 12 as described above, such as... Figure 3-4 As shown, a locking bolt 4 is also provided on the tube body 3 of the fixed section 11, which can abut against the side wall of the adjusting tube 31. By rotating the locking bolt 4 and tightening it against the outer wall of the adjusting tube 31, the adjusted state can be quickly locked, avoiding the instability caused by the relative displacement between the adjusting section 12 and the fixed section 11 during the transfer process.

[0032] To facilitate driving the vehicle body, such as Figure 3 As shown, a drive handle 5 is also hinged to the inner side of the fixed section 11 near the longitudinal direction of the tube body 3. The hinge of the drive handle 5 is preferably made by a hinge bolt, and the drive handle 5 rotates to... Figure 5 The device can be locked after reaching the indicated state, facilitating pushing or pulling after the product is loaded. When not in use, as shown... Figure 7 As shown, the drive handle 5 can be rotated to a horizontal position, flush with the fixed section 11, and placed on the top plate of the caster wheel that extends into the fixed section 11, thereby reducing the overall height of the vehicle body for easier transport. The drive handle 5 is preferably connected to the adjusting section 12 and the fixed section 11 via an adjusting tube 31, which can accommodate operators of different heights.

[0033] like Figure 8 As shown, since the adjusting section 12 is lifted off the ground by rollers 2, products placed on the ground need to be lifted before they can be transferred to the adjusting section 12 and the fixed section 11. When the product is heavy, lifting is difficult. Therefore, for ease of operation, as... Figure 9-10 As shown, a transfer plate 6 (preferably made of high-strength steel plate) is hinged to the longitudinal tube 3 at the front of the adjusting section 12, allowing it to be tilted and supported on the ground. This transfer plate 6 can be flipped to lie flat against the surface of the adjusting section 12. In use, the transfer plate 6 is flipped so that its bottom end contacts the ground, forming an inclined plate structure, thereby... Figure 10-11As shown, the product can be quickly transferred onto the vehicle body along the inclined surface of the transfer plate 6. Compared to directly lifting the product, this method saves effort, improves product transfer efficiency, and reduces physical burden. When not in use, the transfer plate 6 can be flipped onto the adjustment section 11 for mounting. The hinge joint of the transfer plate 6 is typically preferably a hinge bolt. When transferring the product, the transfer plate 6 can be rotated to lock off the ground, preventing the bottom of the transfer plate 6 from continuously contacting the ground and causing obstruction during forward pushing.

[0034] During multiple product transfers, the forward or backward pushing or pulling of the vehicle body, as well as the inertia during the stopping process, cause the product's movement on the adjusting section 12, resulting in the adjusting tube 31 moving relative to the fixed section 11, overcoming the tightening effect of the locking bolt 4. Prolonged forward and backward movement reduces the locking effect of the locking bolt 4 on the adjusting tube 31. Therefore, to solve this problem, such as... Figure 13-14 As shown, the sidewalls of the adjusting tubes 31 located on both longitudinal sides are configured as inclined structures that contact the locking bolts 4 in the opposite transverse direction. Figure 13 As shown, during the process of pushing the vehicle body to the left, the inclined structure of the side wall of the adjusting tube 31 will restrict the forward movement of the locking bolt 4; while as Figure 14 As shown, the side wall of the other adjustment tube 31 is inclined in the opposite direction. When the vehicle body is pulled to the right, the backward movement of the locking bolt 4 is restricted. Thus, when the vehicle body is pushed forward or pulled backward, the opposite inclined structure of the side walls of the two adjustment tubes 31 can stably restrict the movement of the adjustment section 12 relative to the fixed section 11 under the action of product inertia, ensuring the stability of product transfer and avoiding wear on the bottom surface of the product caused by the movement of the adjustment section 12.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
