Description

Technical Field

[0001] This utility model relates to the field of brick handling, specifically to a brick loading and unloading device. Background Technology

[0002] Sintered common bricks and blocks are indispensable materials in building construction. While the loading and unloading of common bricks and blocks is mostly mechanized, manual handling is still unavoidable in some situations at brick factories and construction sites. The standard size of sintered common bricks is 240mm × 115mm × 53mm; typically, one hand can only grasp one or two bricks, making manual handling very inefficient. Furthermore, frequent contact with the rough brick surface can cause hand injuries, and bricks may slip from the hand, leading to accidents and harming workers' health. Therefore, it is necessary to develop a brick loading and unloading tool to replace manual handling. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a brick loading and unloading device, which can solve the problems of low efficiency and adverse effects on workers' health caused by the existing method of manually moving bricks.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a brick loading and unloading device, including a first gripping arm and a second gripping arm. The first gripping arm includes a first rotating rod, a first locking rod and a connecting rod, which are connected in a U-shape. The first rotating rod and the first locking rod are arranged opposite to each other. The second gripping arm includes a second locking rod and a second rotating rod, which are connected in an L-shape. The second rotating rod is arranged crosswise with the first rotating rod and is rotatably connected. The end of the second rotating rod away from the second locking rod is spaced apart from the first locking rod.

[0005] As a further improvement to the above technical solution, the end of the first rotating rod away from the connecting rod is connected to a connecting member. The connecting member includes a connecting block and two gaskets. The connecting block and the two gaskets are connected in a U-shape, and the two gaskets are arranged opposite to each other. The second rotating rod is connected between the two gaskets through a rotating member.

[0006] As a further improvement to the above technical solution, each of the two gaskets is provided with a first through hole, and the second rotating rod is provided with a second through hole. The second through hole and the two first through holes are coaxially arranged. The rotating component includes a screw and a nut. The screw passes through the second through hole and the two first through holes. The nut of the screw and the nut are respectively connected to the two outer sides of the two gaskets. The second rotating rod is rotatably connected to the rod body of the screw.

[0007] As a further improvement to the above technical solution, the second rotating rod is provided with a plurality of second through holes, and each second through hole is arranged along the length direction of the second rotating rod.

[0008] As a further improvement to the above technical solution, the first rotating rod is welded to the connecting block.

[0009] As a further improvement to the above technical solution, the length of the second clamp is greater than the length of the first clamp, and when the first rotating rod and the second rotating rod are perpendicular to each other, the end of the first clamp away from the first rotating rod is flush with the end of the second clamp away from the second rotating rod.

[0010] As a further improvement to the above technical solution, the outer side of the end of the second clamp rod away from the connecting rod and the outer side of the end of the first clamp rod away from the first rotating rod are both provided with chamfers.

[0011] As a further improvement to the above technical solution, the inner sides of both the first and second locking rods are planar.

[0012] As a further improvement to the above technical solution, the first rotating rod, the first locking rod, and the connecting rod are integrally formed; the second rotating rod and the second locking rod are integrally formed.

[0013] As a further improvement to the above technical solution, both the first grip arm and the second grip arm are made of plain round steel bars.

[0014] The beneficial effects of this invention are as follows: In use, the brick is placed between the first and second clamping rods. The connecting rod and the second rotating rod are simultaneously gripped with one hand. Because the second rotating rod is intersecting and rotatably connected to the first rotating rod, with a gap between the end of the second rotating rod away from the second clamping rod and the first clamping rod, as the hand grips tightly, the second rotating rod rotates towards the connecting rod, narrowing the gap between the first and second clamping rods. Under the action of friction, the first and second clamping rods can clamp the brick. Once the brick reaches the designated placement location, the hand is released, and the brick is placed down. This device can transport multiple bricks at once and can be operated with one hand. If both hands are used to transport bricks simultaneously, the number of bricks transported at one time is several times that of manual transport, greatly improving efficiency. Furthermore, the worker's hands do not directly contact the rough bricks, avoiding hand injuries and benefiting the worker's health. Attached Figure Description

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1-3This utility model provides a preferred embodiment of a brick loading and unloading device, including a first gripping arm 1 and a second gripping arm 2. The first gripping arm 1 includes a first rotating rod 11, a first locking rod 12, and a connecting rod 13, which are connected in a U-shape. The first rotating rod 11 and the first locking rod 12 are arranged opposite to each other. The second gripping arm 2 includes a second locking rod 21 and a second rotating rod 22, which are connected in an L-shape. The second rotating rod 22 is crossed and rotatably connected to the first rotating rod 11, and the end of the second rotating rod 22 away from the second locking rod 21 is spaced apart from the first locking rod 12. In use, a brick is placed between the first locking rod 12 and the second locking rod 21, and the connecting rod 13 and the second rotating rod 22 are gripped simultaneously with one hand. Because the second rotating rod 22 is crossed and rotatably connected to the first rotating rod 11, and the end of the second rotating rod 22 away from the second locking rod 21 is spaced apart from the first locking rod 12, while gripping tightly, please refer to [further details omitted]. Figure 2 The second rotating rod 22 rotates towards the connecting rod 13, narrowing the gap between the first clamping rod 12 and the second clamping rod 21. Under the action of friction, the first clamping rod 12 and the second clamping rod 21 can clamp the brick. After reaching the designated placement location, release the handle. Please refer to [link / reference]. Figure 3 The second rotating rod 22 rotates away from the connecting rod 13, widening the gap between the first locking rod 12 and the second locking rod 21, allowing the brick to be lowered. This device can handle multiple bricks at once and can be operated with one hand. If both hands are used to handle bricks, the number of bricks that can be handled at once is several times that of handling them by hand, greatly improving efficiency. Furthermore, the worker's hands do not come into direct contact with the rough bricks, avoiding hand injuries and benefiting the worker's health.

[0025] The first rotating rod 11 is connected to a connector 3 at the end away from the connecting rod 13. The connector 3 includes a connecting block 31 and two washers 32. The connecting block 31 and the two washers 32 are connected in a U-shape, and the two washers 32 are arranged opposite to each other. The second rotating rod 22 is connected between the two washers 32 through a rotating member 4, so that the first gripping arm 1 and the second gripping arm 2 can be located on the same plane. When the first rotating rod 11 and the second rotating rod 22 are perpendicular to each other, the first clamping rod 12 and the second clamping rod 21 are arranged opposite to each other, so that the force can be applied to the brick better when clamping the brick.

[0026] Please see Figure 4Each of the two washers 32 has a first through hole 321, and the second rotating rod 22 has a second through hole 221. The second through hole 221 and the two first through holes 321 are coaxially arranged. The rotating component 4 includes a screw 41 and a nut 42. The screw 41 passes through the second through hole 221 and the two first through holes 321. The nut 42 and the screw 41 are respectively connected to the two outer sides of the two washers 32. The second rotating rod 22 is rotatably connected to the rod body of the screw 41. By disassembling the screw 41 and the nut 42, the device can be disassembled into several parts, reducing its footprint and making it easier to carry.

[0027] The second rotating rod 22 is provided with several second through holes 221. Each second through hole 221 is arranged along the length of the second rotating rod 22. By connecting the screw 41 to the second through holes 221 at different positions, the gap between the first clamping rod 12 and the second clamping rod 21 can be controlled, thereby controlling the number of bricks that can be picked up and put down at one time, which is convenient for use.

[0028] The first rotating rod 11 is welded to the connecting block 31 at point 33, which ensures a firm connection between the first rotating rod 11 and the connecting block 3, preventing the entire device from becoming unusable due to loosening.

[0029] Please see Figure 1 The length of the second clamping rod 21 is greater than the length of the first clamping rod 12, and when the first rotating rod 11 and the second rotating rod 22 are perpendicular to each other, the end of the first clamping rod 12 away from the first rotating rod 11 is flush with the end of the second clamping rod 21 away from the second rotating rod 22. When clamping a brick, the force points of the first clamping rod 12 and the second clamping rod 21 on the brick are at the same height, which further facilitates use.

[0030] The outer side of the end of the second clamping rod 21 away from the connecting rod 13 and the outer side of the end of the first clamping rod 12 away from the first rotating rod 11 are both provided with chamfers 23, which facilitates the clamping of bricks and further facilitates use.

[0031] The inner sides of the first clamp 12 and the second clamp 21 are both flat, which increases the contact area between the first clamp 12 and the second clamp 21 and the brick, which helps to increase the friction with the brick and prevent the brick from falling out.

[0032] The first rotating rod 11, the first locking rod 12, and the connecting rod 13 are integrally formed; the second rotating rod 22 and the second locking rod 21 are also integrally formed, and all components are firmly connected. Specifically, the first rotating rod 11, the first locking rod 12, and the connecting rod 13 are formed by bending the same steel bar; the second rotating rod 22 and the second locking rod 21 are also formed by bending the same steel bar. The U-shaped first gripping arm 1 and the L-shaped second gripping arm 2 are easy to manufacture, and the connection at the bend is firm, resulting in a longer service life for the device.

[0033] Both the first grip arm 1 and the second grip arm 2 are made of smooth round steel bars, with a smooth surface, comfortable grip, and no discomfort to the hand, making them even easier to use.

[0034] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
