Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, specifically a brick transportation device for construction. Background Technology

[0002] In the construction industry, bricks are a core building material, and their transportation efficiency and safety directly affect construction progress, material waste costs, and on-site operational safety. To meet the short-distance brick transportation needs at construction sites, box-type brick transport devices with front doors are widely used in the industry. These devices typically include a transport box body, an internal structure for carrying bricks, and a front door for closing the transport box opening. Loading and unloading bricks are achieved through the opening and closing of the front door, and the transfer is completed with the help of a set of moving wheels. It is an indispensable auxiliary equipment on construction sites. A Chinese utility model patent (publication number: CN220842574U) discloses a brick-carrying and conveying device for building construction. Through the cooperation of the front door, closing baffle, and limiting mechanism, workers can easily place bricks into or remove them from the device, saving them effort when carrying bricks.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, when there are many bricks in the transport box, the front door is subjected to a large outward pushing force from the bricks. The structure of "rotating baffle fitting with L-shaped limiting plate" alone is not enough to withstand the large pushing force for a long time. The rotating baffle is prone to rotate unexpectedly, which may cause the front door to open suddenly and bricks to fall, posing a safety hazard. Therefore, a brick transport device for construction is proposed to address the above. Utility Model Content

[0004] The purpose of this utility model is to provide a brick transportation device for construction. Through the design of structures such as rotating rod, positioning groove, L-shaped fixing block, connecting rod and wedge block, it ensures that the side baffle remains in a stable closed state during the movement of the transportation device, avoiding safety accidents such as bumps and injuries to construction site personnel caused by falling bricks. It effectively ensures the safety and continuity of the construction process and solves the safety hazard of accidental rotation of the rotating baffle, which can lead to the sudden opening of the front door and the falling of bricks.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a brick transportation device for construction, including a transportation box with an inner cavity.

[0007] Both sides of the transport box have unloading ports that connect to the inner cavity of the transport box. Each unloading port is rotatably connected to a side baffle. Both ends of the outer wall of the side baffle are rotatably connected to a rotating rod. The side wall of the rotating rod is provided with a positioning groove.

[0008] Both sides of the transport box are fixed with L-shaped fixing blocks. The L-shaped fixing blocks have rectangular grooves. One side of the L-shaped fixing blocks has a round hole that connects to the rectangular groove. A positioning element is installed in the rectangular groove. One end of the positioning element protrudes from the round hole. When the rotating rod is rotated to fit with the L-shaped fixing block, one end of the positioning element is engaged in the positioning groove.

[0009] Furthermore, the positioning component includes a connecting rod that fits with the round hole with a clearance, one end of which passes through a rectangular groove. A limit ring is fixed to one end of the connecting rod that passes through the round hole. A wedge block is fixed to the end of the connecting rod away from the limit ring. A spring is sleeved on the outer wall of the limit ring, and the two ends of the spring abut against the side wall of the wedge block and the inner wall of the rectangular groove, respectively.

[0010] Furthermore, the inclined surface of the wedge block faces upward, and the two sides and bottom surface of the wedge block slide in contact with the rectangular groove.

[0011] Furthermore, a handle is fixed to the outer wall of the side panel, and the handle has a rubber pad.

[0012] Furthermore, the bottom of the transport box is fixed with four casters, arranged in a rectangular pattern on the bottom surface of the transport box.

[0013] Furthermore, a push handle is fixed to one side of the transport box.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through the design of a rotating rod, positioning groove, L-shaped fixing block, connecting rod, and wedge block, allows for further positioning and locking after the rotating rod and L-shaped fixing block are engaged. This solves the problem in the prior art where the rotating baffle rotates unexpectedly or the front door opens uncontrollably due to the outward pushing force of bricks, vibration during transportation, or slight collisions during loading and unloading operations. It ensures that the side baffle remains stably closed during the movement of the transportation device, avoiding safety accidents such as bumps and injuries to construction site personnel caused by falling bricks, and effectively ensuring the safety and continuity of the construction process.

[0016] This utility model features side baffles on both sides of the transport box, employing a double-door side baffle structure. In actual use, the appropriate side baffle can be flexibly opened according to the spatial conditions of the construction site for loading and unloading bricks, eliminating the need for workers to push the entire transport device to turn around. This greatly reduces site restrictions on loading and unloading operations. At the same time, the double doors support simultaneous or separate brick loading and unloading operations from multiple directions. Compared with the traditional single-door structure, this significantly improves the efficiency of brick loading and unloading, reduces the physical exertion and time wasted by workers due to adjusting the device direction and operating from a single opening, and further accelerates the construction progress.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a brick transportation device for construction, including a transportation box 1. The transportation box 1 has an inner cavity, wherein the bottom of the inner cavity of the transportation box 1 is covered with a rubber anti-slip pad (with diamond-shaped anti-slip patterns pressed on the surface), which can reduce the sliding displacement of the bricks caused by bumps during transportation and avoid the bricks from colliding and breaking.

[0025] A push handle (made of Φ30~35mm seamless steel pipe bent into shape, 1000~1200mm high, suitable for adults to push while standing) is welded to one side of the outer wall of the transport box 1. The outer wall of the push handle is covered with an 8~10mm thick EVA anti-slip sleeve (with anti-slip protrusions pressed on the surface) to improve grip comfort and prevent hand slippage.

[0026] Both sides of the transport box 1 are provided with unloading ports 10 that connect to the inner cavity of the transport box 1. Both unloading ports 10 are rotatably connected to side baffles 2 via rotating shafts. Handles 21 are fixed on the outer wall of the side baffles 2. The handles 21 have rubber pads. Rotating rods 20 are rotatably connected to both ends of the outer wall of the side baffles 2. Positioning grooves 200 are provided on the side wall of the rotating rods 20.

[0027] Both sides of the transport box 1 are fixed with L-shaped fixing blocks 3. The L-shaped fixing blocks 3 have rectangular grooves 30. One side of the L-shaped fixing blocks 3 has a circular hole 31 that connects to the rectangular groove 30. A positioning element is provided in the rectangular groove 30. One end of the positioning element passes through the circular hole 31. When the rotating rod 20 rotates to fit with the L-shaped fixing block 3, one end of the positioning element is engaged in the positioning groove 200.

[0028] Furthermore, the positioning component includes a connecting rod 4 that fits with the round hole 31 with a clearance and one end of which passes through the rectangular groove 30. A limit ring 40 is fixed to one end of the connecting rod 4 that passes through the round hole 31. A wedge block 41 is fixed to the end of the connecting rod 4 that is away from the limit ring 40. A spring 42 is sleeved on the outer wall of the limit ring 40. The two ends of the spring 42 abut against the side wall of the wedge block 41 and the inner wall of the rectangular groove 30, respectively.

[0029] The connecting rod 4 is a No. 45 steel optical shaft, which is clearance-fitted with the round hole 31 (fit clearance 0.5~1mm) to ensure that the connecting rod 4 can move flexibly axially.

[0030] The limiting ring 40 is a 304 stainless steel ring with a diameter larger than that of the connecting rod 4. It is fixed to one end of the connecting rod 4 by welding and is used to limit the displacement of the spring 42 and facilitate the worker's pressing operation.

[0031] The wedge block 41 is forged from 45 steel and then precision ground. The angle between its inclined surface and the horizontal plane is 30°-45° (this angle can balance the smoothness of the rotating rod compression and the stability of locking. If the angle is too small, it is easy to jam, and if the angle is too large, it is easy to disengage). The two sides and the bottom surface of the wedge block 41 are in sliding fit with the rectangular groove 30 (fit clearance 0.1-0.3mm), ensuring that the wedge block 41 can only move along the axial direction of the rectangular groove 30.

[0032] Spring 42 is a cylindrical helical compression spring. In its natural state, it can push one end of the wedge block 41 out of the rectangular groove 30 to ensure that the positioning groove 200 can be quickly inserted after alignment.

[0033] The inclined surface of the wedge block 41 faces upward, and the two sides and bottom surface of the wedge block 41 slide in contact with the rectangular groove 30.

[0034] The bottom of transport box 1 is fixed with four casters, which are arranged in a rectangle on the bottom surface of transport box 1.

[0035] The casters at the bottom of transport box 1 are made of polyurethane and are fixed to the four corners of the bottom of transport box 1 by bolts (M8-M10 flange bolts) (in a rectangular distribution with the spacing adapted to the length and width of transport box 1).

[0036] Each caster wheel is equipped with a foot-operated brake mechanism (the brake pads are made of wear-resistant cast iron, and the brake travel is 5-8mm). Pressing the brake pedal will lock the wheel and prevent the device from slipping when loading and unloading bricks.

[0037] The caster wheels use deep groove ball bearings (model 6204) to reduce wheel rotation resistance and ensure that the device can move flexibly on rough construction surfaces such as gravel and cement.

[0038] When using the above device:

[0039] After the bricks are loaded, the worker holds handle 21 and rotates the side baffle 2 towards the transport box 1. When it is parallel to the side wall of the transport box 1, the worker rotates the rotating rod 20 towards the L-shaped fixing block 3. During the rotation, the rotating rod 20 contacts the inclined surface of the wedge block 41. With the pressure applied by the worker, the rotating rod 20 squeezes the wedge block 41 and compresses the spring 42 until the rotating rod 20 is completely in contact with the surface of the L-shaped fixing block 3. At this time, the positioning groove 200 on the rotating rod 20 is aligned with the position of the wedge block 41, the elastic force of the spring 42 is released, and the wedge block 41 is pushed to reset along the rectangular groove 30. One end of the wedge block 41 is inserted into the positioning groove 200, realizing the axial locking of the rotating rod 20.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
