Description

Technical Field

[0001] This utility model relates to the field of pavement concrete construction technology; specifically, this utility model relates to a set of cement concrete pavement reinforcing steel mesh transportation and placement device. Background Technology

[0002] In pavement concrete construction, reinforcing mesh is installed within the concrete as a protective measure to prevent uneven settlement and slab breakage. The quality of the finished product and the accuracy of its placement are particularly important. Pre-fabricated reinforcing mesh is typically processed on-site and then stacked in a designated area. When construction reaches the concrete slab where the mesh needs to be placed, it is manually lifted and transported. The heavy weight of the pre-fabricated mesh makes it highly susceptible to bending, twisting, and impacts during transport due to uneven force applied manually, leading to damage to welds or binding points and compromising the mesh's integrity. Furthermore, manual lifting and installation of the reinforcing mesh results in significant deviations, easily causing the concrete blocks to slip, requiring repeated adjustments, which is difficult, time-consuming, and labor-intensive.

[0040] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0041] like Figures 1 to 6 As shown in Embodiment 1, a set of cement concrete pavement reinforcement steel mesh transportation and placement device includes:

[0042] The transport frame 1 is capable of moving on the ground, and the top of the transport frame 1 is provided with a cavity that can hold the steel mesh.

[0043] The placement frame 2 is able to walk on the ground and can be attached to the outside of the transport frame 1. The interior of the placement frame 2 is equipped with hooks 2-6, which are used to lift the steel mesh and place the steel mesh.

[0044] Specifically, the transport frame 1 consists of inner uprights, outer uprights, upper crossbars, bottom crossbars, and casters. The casters are installed at the bottom of the bottom crossbar. The side uprights, outer uprights, upper crossbars, and bottom crossbars are assembled into a cavity that can hold the steel mesh. The placement frame 2 consists of inner uprights, outer uprights, upper crossbars, bottom crossbars, and casters. The casters are installed at the bottom of the bottom crossbar. The two ends of the placement frame 2 are designed to be open, making it easy to fit onto the outside of the transport frame 1.

[0045] In use, the steel mesh is first placed in the cavity, and the mounting frame 2 is attached to the outside of the transport frame 1. The transport frame 1 and the mounting frame 2 are moved as a whole to transport the steel mesh. When the steel mesh is transported to the appropriate position, the hook 2-6 is connected to the uppermost steel mesh, and the mounting frame 2 is moved so that the hoisted steel mesh is transported to the place where it needs to be installed.

[0046] The mounting rack 2 includes:

[0047] The cross brace 2-1 is arranged at an angle and crosswise, serving as the top structure of the mounting frame 2;

[0048] Manual lifting wheels 2-2 are provided at each of the four corners corresponding to the cross brace 2-1;

[0049] Fixed pulleys 2-3 are provided at each of the four corners of the cross brace 2-1, and fixed pulleys 2-3 are rotatably installed at the bottom of the cross brace 2-1;

[0050] A movable pulley 2-4 is provided for each fixed pulley 2-3. The movable pulley 2-4 is located below the fixed pulley 2-3. The movable pulley 2-4 is connected to the hook 2-6 and is used to lift the steel mesh.

[0051] The steel wire rope 2-5 is suspended at the bottom of the fixed pulley 2-3, and its top end passes over the bottom of the movable pulley 2-4 and the top of the fixed pulley 2-3 from bottom to top, and is fixedly connected to the manual lifting wheel 2-2.

[0052] After connecting the hook 2-6 to the uppermost steel mesh, rotate the manual lifting wheel 2-2 to wind up the wire rope 2-5. At this time, the wire rope 2-5 drives the fixed pulley 2-3 and the movable pulley 2-4 to rotate. The movable pulley 2-4 rises, causing the hook 2-6 to rise and lift the steel mesh to a height that can be separated from the transport frame 1. Then move the placement frame 2 to move the steel mesh. When the steel mesh is moved to the designated location, rotate the manual lifting wheel 2-2 in the opposite direction to lower the steel mesh, completing the installation of the steel mesh.

[0053] like Figures 7 to 10 As shown, in Embodiment 2, the mounting frame 2 further includes:

[0054] The lifting rod 3 is slidably mounted on the outer surface of the mounting frame 2;

[0055] The connecting part 4 includes a buckle plate 4-2, which is L-shaped and is rotatably installed at the bottom of the lifting rod 3. The buckle plate 4-2 can fasten the bottom of the transport frame 1 and is used to connect the transport frame 1 and the placement frame 2.

[0056] When the lifting plate 3 moves, it can drive the buckle plate 4-2 to move. When the lifting rod 3 descends, the buckle plate 4-2 is blocked by the bottom of the mounting frame 2, causing the end of the buckle plate 4-2 to deflect upward and move away from the bottom of the transport frame 1. When the buckle plate 4-2 swings to the vertical position, the mounting frame 2 and the transport frame 1 separate. At this time, the mounting frame 2 can be moved alone to transport the steel mesh to the designated position.

[0057] When the lifting rod 3 rises, the side of the buckle plate 4-2 loses the restraining effect of the outer side of the bottom of the mounting frame 2. Under the action of its own weight, the end of the buckle plate 4-2 deflects downward. At this time, the buckle plate 4-2 can hold the bottom of the transport frame 1 and the mounting frame 2 together, connecting the bottom of the transport frame 1 and the mounting frame 2 together, preventing the transport frame 1 and the mounting frame 2 from moving as a whole and separating.

[0058] The mounting rack 2 also includes:

[0059] The locking part 5 includes a locking rod 5-2, which is rotatably mounted at the top of the lifting rod 3. When the locking rod 5-2 is deflected upward, it can lock the wire rope 2-5 at the bottom of the cross brace 2-1.

[0060] Specifically, the bottom of the cross brace 2-1 is provided with a groove, and the locking rod 5-2 can be inserted into the groove;

[0061] When the lifting plate 3 moves, it can drive the locking rod 5-2 to move. When the lifting rod 3 descends, the locking rod 5-2 cooperates with the mounting frame 2, and its end will deflect upward. When the locking rod 5-2 deflects upward, it contacts the bottom of the wire rope 2-5 and drives the wire rope 2-5 to bend upward. When the locking rod 5-2 drives the wire rope 2-5 to bend upward, and the locking rod 5-2 is inserted into the groove, it can lock the wire rope 2-5 in the groove and lock the wire rope 2-5.

[0062] When the lifting rod 3 rises, the locking rod 5-2 is blocked by the cross brace 2-1 and its own weight. The end of the locking rod 5-2 deflects downward and disengages from the groove, unlocking the wire rope 2-5.

[0063] Locking part 5 also includes:

[0064] The trigger rod 5-3 is fixedly installed on the locking rod 5-2. The trigger rod 5-3 can contact the top of the mounting bracket 2 to drive the locking rod 5-2 to rotate.

[0065] When the lifting plate 3 moves, it can drive the trigger rod 5-3 to move. When the lifting rod 3 descends, the end of the trigger rod 5-3 contacts the top of the mounting frame 2. As the lifting rod 3 continues to descend, the trigger rod 5-3 is blocked by the mounting frame 2, causing its end to deflect upward and drive the locking rod 5-2 to deflect upward, locking the wire rope 2-5.

[0066] When the lifting rod 3 rises, the trigger rod 5-3 is subjected to its own gravity and the gravity of the locking rod 5-2, causing the trigger rod 5-3 to deflect downwards so that it can still contact the mounting bracket 2 and deflect upwards when used next time.

[0067] Locking part 5 also includes:

[0068] Limiting rod 5-4 is fixedly installed on locking rod 5-2;

[0069] Limit block 5-5 is set between limit rod 5-4 and trigger rod 5-3.

[0070] When the lifting rod 3 rises, the trigger rod 5-3 deflects downward and drives the limit rod 5-4 to deflect. When the limit rod 5-4 deflects to contact the limit block 5-5, the limit rod 5-4 is blocked by the limit block 5-5, so that when the limit rod 5-4 deflects downward to the maximum distance, the angle between the trigger rod 5-3 and the top of the mounting bracket 2 is less than 90 degrees, so that the trigger rod 5-3 can still drive the locking rod 5-2 to deflect upward when used next time.

[0071] The mounting rack 2 also includes:

[0072] The movable plate 4-1 is rotatably connected to the bottom end of the lifting rod 3, and the movable plate 4-1 is in contact with the outer surface of the mounting frame 2;

[0073] The limiting frame 5-1 is rotatably connected to the top of the lifting rod 3, and the limiting frame 5-1 is sleeved on the top of the mounting frame 2;

[0074] The sliding sleeve 6 is fixedly installed on the outer surface of the mounting frame 2 and slides with the lifting rod 3. A Z-shaped groove 6-1 is provided on the sliding sleeve 6.

[0075] The handle 3-1 is fixedly installed on the lifting rod 3 and can slide within the Z-shaped groove 6-1.

[0076] Specifically, the locking rod 5-2 is rotatably connected to the side of the limiting frame 5-1 away from the lifting rod 3, and the buckle plate 4-2 is rotatably connected to the side of the moving plate 4-1;

[0077] Handle 3-1 controls the lifting rod 3 to rise and fall. When handle 3-1 moves in the longitudinal groove of Z-shaped groove 6-1, it can drive the lifting rod 3 to rise and fall. When handle 3-1 moves to the transverse groove of Z-shaped groove 6-1, handle 3-1 can be locked in sliding sleeve 6, so that the lifting rod 3 can be kept in the highest or lowest position.

[0078] When the handle 3-1 moves into the horizontal groove of the Z-shaped groove 6-1, the lifting rod 3 will rotate. At this time, the limiting frame 5-1 is sleeved on the top of the mounting frame 2, which can prevent the limiting frame 5-1 from rotating and keep the direction of the locking rod 5-1 unchanged, so that the locking rod 5-2 can be inserted into the groove each time it is used to lock the wire rope 2-5.

[0079] When the lifting rod 3 rotates, the moving plate 4-1 fits against the outer surface of the mounting frame 2, maintaining its orientation and keeping the position of the buckle plate 4-2 unchanged. This ensures that the buckle plate 4-2 can be fastened to the bottom of the transport frame 1 and the mounting frame 2 each time it is used, connecting the transport frame 1 and the mounting frame 2 into a whole.

[0080] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
