Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to material transfer vehicles for building construction. Background Technology

[0002] Material handling is a frequent and crucial task during construction. Material carts, as a common material handling tool, are widely used on various construction sites due to their ease of operation and high flexibility. However, when using material carts to transfer non-solid materials, such as highly fluid concrete or water, the uneven and potholed terrain often causes severe bumps and shaking. For non-solid materials, this shaking can easily lead to spillage from the cart.

[0003] Meanwhile, existing material carts are frequently subjected to impacts and friction from materials during long-term use. Especially when transferring materials with hardness and sharp edges, such as sand and gravel, the side panels are easily scratched and bumped, resulting in dents and uneven surfaces. To address the issue of material spillage, some construction workers have tried using covers to shield the carts. However, common covers either lack a secure seal or have complex fixing methods, making them inconvenient to use.

[0004] Chinese patent application number 2020206482390 proposes a material transfer vehicle for construction, belonging to the field of construction technology. It includes a vehicle body with a slot on the vehicle body and a fixing plate welded and fixed on the top of the vehicle body. A vibration damping pad is engaged and connected inside the slot. A telescopic rod is fixedly connected to one side of the fixing plate by a screw. A clamping plate is welded and fixed to one side of the telescopic rod. A sliding groove is provided on the clamping plate, and a threaded hole is provided on the inner surface wall of the sliding groove.

[0005] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the aforementioned patents do not provide a sealing effect during the transfer of non-solid materials. Utility Model Content

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a material transfer vehicle for construction. For example... Figure 1 and 2As shown, the vehicle includes a body for holding materials, comprising a front panel, a rear panel, and two side panels 1. A storage box 2 is screwed onto the rear panel near the handlebars. The storage box 2 has a hollow rectangular box structure and contains a shield that extends to the front panel to cover the vehicle body. A take-up roller 3 for storing the shield is located inside the storage box 2. The take-up roller 3 is prior art. A slot 8 for rotatably connecting the take-up roller 3 is provided on the inner wall of the storage box 2. A coil spring, also prior art, is provided at the end of the take-up roller 3 to reset it after rotation. An opening for removing the shield is provided on the storage box 2. Multiple guide rollers 5, also prior art, are provided on the inner wall of the storage box 2 to guide the movement of the shield. The baffle includes two long plates 4 hinged together end to end. Each long plate 4 has connecting ears 6 on both sides of one end, forming an integral structure with the long plate 4. Two grooves are provided on the end of the long plate 4 furthest from the connecting ears 6, symmetrically arranged about the long plate 4. A connecting rod 7 is located at the groove position on the long plate 4. Connecting holes for cooperation with adjacent connecting rods 7 are provided on the connecting rods 7. A torsion spring, which is existing technology, is fitted onto the connecting rod 7. Each long plate 4 has a movable clamping plate at both ends, which can be moved to a side plate 1 to fix the baffle to the side plate 1. A fixing plate 18 is screwed onto the long plate 4 at one end of the baffle, and a magnet is glued to the fixing plate 18, forming a structure where the baffle covers the vehicle body and, under the action of the clamping plate and the magnet, prevents excessive material from moving out of the vehicle body.

[0023] In one embodiment, according to the appendix Figure 3 and 4As shown, the long plate 4 is provided with a slot 8 for placing the card plate. The card plate includes a base plate 9 and an extension plate 10. The base plate 9 is hinged to the long plate 4. The slot 8 has a rectangular structure and is used to limit the base plate 9 to be rotated 90 degrees and positioned by the edge of the slot 8. A counterweight 11 is screwed to one end of the base plate 9. The counterweight 11 has a long strip structure and forms a structure in which the shielding plate is placed vertically by gravity after it is removed from the placement box 2. A placement groove 12 for placing the extension plate 10 is provided inside the base plate 9. The placement groove 12 has a rectangular structure. One end of the extension plate 10 is hinged to the base plate 9, and the other end of the extension plate 10 is provided with a first spring 12 connected to the inner wall of the placement groove 12. Each extension plate 10 is provided with a through hole, which communicates with the placement groove 12. A rope 15 passes through each through hole from the take-up roller 3 and extends to one end of the shielding plate. The rope 15 is equipped with push blocks 14 for moving each extension plate 10. The push blocks 14 are isosceles right trapezoidal structures. The base plate 9 is equipped with a rectangular groove 16 that communicates with the slot 8 and is used to place the push blocks 14. This forms a structure where pulling the rope 15 pushes the extension plates 10 to move, and the card plate presses against the side plate 1 and fixes the shield plate by relying on the slot 8. A second spring 17 is sleeved on the outside of the rope 15 located between the base plate 9 and the push blocks 14. A fixing post is provided on the front plate to fix the rope 15. After the shield plate covers the vehicle body, pulling the rope 15 compresses the second spring 17, and the push blocks 14 press against the base plate 9 and the extension plates 10, and fix the rope 15 by the fixing post. A tray is fixed to the storage box 2 with screws, forming a structure where when the card plate moves to the storage box position, the card plate rotates by relying on the tray and enters the slot 8.

[0024] The implementation principle of the construction material transfer vehicle in this application embodiment is as follows: Pulling the shield, the shield gradually unfolds under the guidance of the guide roller 5 until it extends to the front plate position; the clamping plate hangs down naturally and is placed vertically under the action of the counterweight 11; pulling the rope 15, the rope 15 drives the push block 14 to move forward. Since the push block 14 has an isosceles right trapezoidal structure, the push block 14 pushes the extension plate 10 to rotate around its hinge point with the base plate 9 during the movement. The extension plate 10 gradually extends out of the placement groove 12 of the base plate 9 and squeezes the side plate 1, thereby firmly fixing the shield to both sides of the vehicle body. The magnet on the fixing plate 18 is attracted to the front plate, further enhancing the fixing effect of the shield.

[0025] When the material is transferred to its destination and needs to be unloaded, first loosen the rope 15. Under the action of the first spring 12, the extension plate 10 automatically retracts into the placement slot 12 of the base plate 9, and the card plate separates from the side plate 1. Push the shielding plate towards the placement box 2. Under the action of the coil spring, the winding roller 3 automatically retracts the shielding plate into the placement box 2. During the process of shielding plate retraction, when the card plate moves to the position of the placement box 2, the card plate, supported and guided by the support plate, rotates and enters the slot 8 on the long plate 4, completing the storage of the shielding plate.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
