Abstract
Description
Technical Field
[0001] This utility model relates to the field of stone handling, and in particular to a stone laying auxiliary device with angle adjustment. Background Technology
[0002] During the construction of ground stone paving, the stones to be laid are heavy and cover a large area, requiring manual handling to move them to the designated construction location. After a trial paving, the stones are lifted again for mortar placement. The stones are heavy, and during the handling and laying process, the hands come into direct contact with the stones, making it easy to bump or crush the hands during the process.
[0003] Existing stone paving and handling devices have certain drawbacks. First, most existing handling devices have complex structures and are inconvenient to manufacture. They also require material handling and unloading before the handling work can be completed, resulting in low construction efficiency. To address this, we propose a stone paving auxiliary device with angle adjustment. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a stone paving auxiliary device with adjustable angle. By setting up a transport device body and a lower bending part, the main structure of the device forms a Z-shape with the transport device body and the lower bending part. The middle height of the transport device body is determined according to the height of the construction workers. This design makes the device more convenient for transporting. Each user holds two of the devices, requiring two people to work together. The lower bending part hooks into the bottom of the stone, and both people hold the upper handle bending part, simultaneously lifting the stone and moving it to the stone installation location. Space is reserved for removing the transport device. If there is stone nearby, the transport device can be turned and withdrawn. In the empty area, the transport device can be directly withdrawn, allowing for convenient transport and transfer of the stone. This device has a simple structure, is easy to manufacture for ground stone transport, shortens material transport time, significantly improves construction efficiency, and has good practical effects.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A stone paving auxiliary device with angle adjustment includes a main body mechanism, wherein the outer end of the main body mechanism is hinged to a limiting structure.
[0007] The main body mechanism includes a conveying device body, and a lower bending part is installed at the lower end of the conveying device body.
[0008] By installing the main body of the handling device and the lower bending part, the ground stone handling device is simple to manufacture, shortens the material handling time, greatly improves construction efficiency, and has good practical effect.
[0009] Furthermore, a handle bend is installed at the upper end of the main body of the conveying device, and a protective sleeve is fitted over the outer end of the handle bend.
[0010] By installing a hand-bending section, the protective effect of this stone paving auxiliary device structure is improved, avoiding hand wear during construction.
[0011] Furthermore, a reinforcing layer is provided on the outer end of the protective sleeve.
[0012] By installing a reinforcement layer, the stability of the connections between the structures of the device was improved.
[0013] Furthermore, a reinforcing rib is fixedly connected to the inner end of the main body of the conveying device.
[0014] By installing reinforcing ribs, the service life of the handling device body is further improved.
[0015] Furthermore, a hinge seat is installed at the outer end of the main body of the conveying device.
[0016] Installing a hinge mount makes the connection between the lifting lever and the transport device body more stable.
[0017] Furthermore, the inner end of the hinge seat is hinged to a lifting rod, the bottom end of the lifting rod is fitted with a connecting seat, and the lower end of the lifting rod is fixedly connected to an anti-detachment pad.
[0018] The handling efficiency of this stone paving auxiliary device has been further improved by installing lifting rods and anti-detachment pads.
[0019] Furthermore, the inner end of the connecting seat is hinged to an automatic telescopic rod.
[0020] Installing a connector makes the connection of the automatic telescopic pole more stable.
[0021] Furthermore, the other end of the automatic telescopic rod away from the connecting seat is hinged to a reinforcing seat, which is located at the outer end of the transport device body.
[0022] The installation of reinforcement brackets further improved the connection effect of the device structure.
[0023] In summary, this utility model has the following beneficial effects:
[0024] 1. By setting the main body of the transport device and the lower bending part, the main structure of the device is set up with the main body of the transport device and the lower bending part to form a Z-shaped structure. The middle height of the transport device body is determined according to the height of the construction personnel. This design makes it more convenient for the device to be transported. When using it, each user holds two of the devices. During construction, two people are required to work together. The lower bending part hooks into the bottom of the stone, and the two people hold the upper handle bending part and lift the stone at the same time to move it to the stone installation position. Space is reserved for the removal of the transport device. If there is stone next to it, the stone transport device can be turned and withdrawn. The empty area next to it can be directly removed from the transport device, which can facilitate the transportation and transfer of the stone. The device has a simple structure, is easy to make on the ground, shortens the material transportation time, can greatly improve construction efficiency, and has good practical effect.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0035] Reference Figure 1-5 As shown, this is a preferred embodiment of the present invention of a stone paving auxiliary device with angle adjustment, including a main body mechanism 1, and a limit structure 2 connected to the outer end of the main body mechanism 1 by a hinge.
[0036] The main body mechanism 1 includes a conveying device body 101, and a lower bending part 102 is installed at the lower end of the conveying device body 101.
[0037] Reference Figure 1-3 As shown, a handle bending part 103 is installed at the upper end of the main body 101 of the conveying device, and a protective sleeve 104 is fitted on the outer end of the handle bending part 103.
[0038] Reference Figure 1 As shown, the outer end of the protective sleeve 104 is further provided with a reinforcing layer 105.
[0039] The main structure of the device, consisting of a transport device body 101 and a lower bending section 102, forms a Z-shaped structure. The transport device body 101 is made of C12 steel reinforcement, and the lower bending section 102 is 40mm in diameter for transporting stone. The height of the transport device body 101 is determined based on the height of the construction workers. This design facilitates the transport of the device. Each user holds two handles, requiring two people to work together. The lower bending section 102 hooks into the bottom of the stone, and both users hold the upper handle bending section 103, simultaneously lifting the stone and moving it to the installation location. A provision is made for the removal of the transport device. With space available and stone materials nearby, the stone handling device can be turned and withdrawn, leaving empty space for easy removal and transfer of the stone. This simplifies the device's structure. The handle bend 103 is 90mm long, and a protective sleeve 104 is installed at the outer end of the handle bend 103. The protective sleeve 104 is made of protective material combined with wrapped fabric material and then secured with tape. The reinforcing layer 105 is a protective material with anti-loosening texture on the outside. The reinforcing layer 105 connects the protective sleeve 104 to the outer end of the handle bend 103, increasing the protective effect of the protective sleeve 104 and improving the stability of the connections between the device's structures.
[0040] Reference Figure 1 and Figure 3As shown, a reinforcing rib 106 is further fixedly connected to the inner end of the conveying device body 101.
[0041] By installing reinforcing ribs 106, a reinforcing structure can be formed inside the conveying device body 101, making the overall structure of the conveying device body 101 more robust, preventing the conveying device body 101 from breaking during use, and further improving the service life of the conveying device body 101.
[0042] Reference Figure 1-4 As shown, a hinge seat 201 is further installed on the outer end of the conveying device body 101.
[0043] Reference Figure 4 and Figure 5 As shown, the inner end of the hinge seat 201 is hinged to a lifting rod 202, the bottom end of the lifting rod 202 is fitted with a connecting seat 203, and the lower end of the lifting rod 202 is fixedly connected to an anti-detachment pad 206.
[0044] Reference Figure 4 As shown, the inner end of the connecting seat 203 is further hinged to an automatic telescopic rod 204.
[0045] Reference Figure 4-5 As shown, further, the other end of the automatic telescopic rod 204 away from the connecting seat 203 is hinged to a reinforcing seat 205, which is located at the outer end of the conveying device body 101.
[0046] By installing the hinge seat 201, a connecting structure can be formed at one end of the lifting rod 202, making the connection between the lifting rod 202 and the transport device body 101 more stable. After the device lifts the stone, the automatic telescopic rod 204 can be activated according to the transfer distance to move the normally vertical lifting rod 202 downward. With the angle adjustment, the lifting rod 202, together with the bottom anti-detachment pad 206, forms a limiting structure on the outside of the stone, which can help the device to have a certain limiting structure on the outside when lifting and transporting the stone. The connecting seat 203 can form a connecting structure at one end of the automatic telescopic rod 204, and the reinforcing seat 205 can stably connect the automatic telescopic rod 204 to the outer end of the transport device body 101, further improving the connection effect of the device structure.
[0047] Specific implementation process: When using this device for transportation, each person uses a pair of transportation device bodies 101. The lower bending part 102 hooks into the bottom of the stone. The transportation device body 101 is made of C12 steel bars. The lower bending part 102 is 40mm in diameter for transporting the stone, and the middle height is 700mm, which is determined according to the height of the construction personnel. This design makes it easier for the device to be used for transportation. The reinforcing rib 106 can form a reinforcing structure inside the transportation device body 101, making the overall structure of the transportation device body 101 more robust and preventing the transportation device body 101 from breaking during use. This increases the stability of the device structure during transportation and prevents the stone from falling off the ground. At this time, the two people hold the upper handle and lift the stone with force, move it to the stone installation position, leave space for the transportation device to be removed, and then turn the transportation device body 101 to withdraw. The transportation device can be directly withdrawn from the empty area next to it, thus completing the transportation work conveniently.
