Description

Technical Field

[0001] This utility model belongs to the field of auxiliary technology for road shoulder stone paving, and in particular relates to an auxiliary tooling for road shoulder stone paving. Background Technology

[0002] Road shoulder stone paving refers to the process of placing and fixing pre-made road shoulder stones along the edges of both sides of the road according to certain design requirements and construction techniques. Road shoulder stones are also often called curb stones or curb stones. They are usually long and strip-shaped and come in a variety of materials.

[0003] Since road shoulder stones are mostly made of concrete and are generally large in size, they are difficult to lift manually. Therefore, auxiliary equipment is often used to move them. For example, patent number CN202423105644.5 discloses a technical solution for the auxiliary movement and laying of road shoulder stones. However, this technical solution still has some problems in use. The solution involves two people holding handles and pushing clamps to hold the stone. At the same time, the two people lift the handles upwards to move the stone to a suitable position. However, in actual use, because the stone is relatively heavy and the pace and force applied by the two people may not be consistent, the stone may fall when the equipment moves it. This is not only time-consuming and laborious, but also inconvenient to use, thus affecting the effectiveness of the equipment. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an auxiliary tool for laying road shoulder stones, which solves the problem that the existing equipment is not convenient to use and is prone to stone falling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for paving road shoulders, comprising two clamping plates for clamping the stone, a pressing plate slidably disposed on the clamping plates, and an air cavity between the clamping plates and the pressing plate, and mounting frames respectively disposed on both sides of the two clamping plates, and further comprising: a lifting assembly disposed on the mounting frames, which drives the stone to be lifted when the two clamping plates approach each other, comprising a fixing pipe fixedly disposed on the mounting frames, a piston rod slidably disposed within the fixing pipe, and an auxiliary wheel disposed at the end of the piston rod for moving the equipment.

[0006] Preferably, the number of auxiliary wheels is at least two sets, and each set contains at least two wheels.

[0007] Preferably, the lifting assembly further includes a control box that passes through the end of the fixed tube, and the control box and the air chamber in the clamp are interconnected through an air pipe. A reset spring for resetting the piston rod is also sleeved between the fixed tube and the piston rod.

[0008] Preferably, each of the two clamping plates has a handle on its upper side, and a rotating rod is provided between the two handles. The mounting bracket is fixedly mounted on the rotating rod, and the two handles are limited by the installed limiting components.

[0009] Preferably, the limiting component includes an L-shaped rotating frame rotatably mounted on one of the handles, a locking rod slidably mounted on the rotating frame, and a limiting spring for limiting the locking rod is sleeved on the locking rod. The other handle has an insertion slot for the limiting spring to be inserted.

[0010] The beneficial effects of this utility model are as follows: the extrusion plate in the device compresses the gas in the air chamber, and the gas is used as power to drive the piston rod to slide in the fixed tube. In combination with the clamping force of the two clamping plates, the stone can be effectively lifted. At the same time, the auxiliary wheel at the bottom of the piston rod allows only one person to move the stone during use, thereby further improving the ease of movement of the device and avoiding the inconsistency in pace and force caused by two people moving at the same time, which would affect the transportation of the stone. The device has a simple and compact structure, which further improves the practicality and ease of use of the device. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. 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.

[0018] according to Figures 1 to 4 As shown, an auxiliary tooling for paving shoulder stones includes two clamping plates 1 for holding stone 2, an extrusion plate 3 slidably disposed on the clamping plates 1, and an air cavity 4 formed between the clamping plates 1 and the extrusion plate 3. Mounting brackets 5 are respectively provided on both sides of the two clamping plates 1. The tooling also includes:

[0019] The lifting assembly is mounted on the mounting frame 5. When the two clamping plates 1 approach each other, it drives the stone 2 to lift. It includes a fixed tube 6 fixedly mounted on the mounting frame 5 and a piston rod 7 slidably mounted in the fixed tube 6.

[0020] An auxiliary wheel 8 is located at the end of the piston rod 7 for moving the equipment.

[0021] As a preferred embodiment of this utility model, the number of auxiliary wheels 8 is at least two sets, with at least two in each set. This can effectively ensure the stability of the stone material 2 during transportation and prevent it from shaking and slipping during transportation. At the same time, the use of auxiliary wheels 8 can effectively save manpower and make the equipment more compact and convenient to use.

[0022] As a preferred embodiment of this utility model, the lifting assembly further includes a control box 10 that passes through the end of the fixed pipe 6, and the control box 10 and the air chamber 4 in the clamping plate 1 are interconnected by an air pipe 11. A reset spring 9 for resetting the piston rod 7 is also sleeved between the fixed pipe 6 and the piston rod 7. When the two clamping plates 1 approach each other to clamp the stone 2, the gas generated in the air chamber 4 pushes the piston rod 7 down, thereby lifting the stone 2. At the same time, the gas between the piston rod 7 and the fixed pipe 6 can act as a buffer to effectively cushion the transported stone 2.

[0023] As a preferred embodiment of this utility model, each of the two clamping plates 1 is provided with a handle on its upper side, and a rotating rod is provided between the two handles. The mounting bracket 5 is fixedly mounted on the rotating rod. The two handles are limited by the installed limiting components, which makes it easier to drive the two clamping plates 1 to move closer to each other. By utilizing the lever principle, it is more convenient and less strenuous for the two clamping plates 1 to move closer to each other.

[0024] As a preferred embodiment of this utility model, the limiting component includes an L-shaped rotating frame 12 rotatably mounted on one of the handles, a locking rod 13 slidably mounted on the rotating frame 12, and a limiting spring 14 for limiting the locking rod 13 is sleeved on the locking rod 13. The other handle has an insertion slot for the limiting spring 14 to be inserted, which facilitates limiting the two handles, keeping the two handles close together when the equipment moves, and further ensuring that the clamping of the two clamping plates 1 is more stable.

[0025] The working principle of this utility model:

[0026] refer to Figure 2 and Figure 3 In the initial state of the equipment, an air chamber 4 is formed between the extrusion plate 3 and the clamping plate 1, and the two clamping plates 1 are far apart. The piston rod 7 is located inside the fixed tube 6, and the return spring 9 is compressed. When the equipment needs to transport the stone 2, the clamping plates 1 are placed on both sides of the stone 2, and the two auxiliary wheels 8 are located on the other two sides of the stone 2. At this time, the two clamping plates 1 and the two auxiliary wheels 8 form a quadrilateral. Then, the two handles are pulled closer together. (Refer to...) Figure 1 When the two handles are brought close together, Figure 3 When the extrusion plate 3 is compressed, it moves towards the inner wall of the air chamber 4. At this time, the extrusion plate 3 compresses the air in the air chamber 4, causing the gas to be discharged through the air pipes 11 on both sides. Simultaneously, the gas in the air pipes 11 enters the control box 10, and is then pushed by the control box 10 to... Figure 4 Inside the fixed tube 6, when the upper side of the fixed tube 6 is pushed by gas, the gas pressure will push the piston rod 7 down, causing the piston rod 7 to extend based on the fixed tube 6. As the piston rod 7 extends, the auxiliary wheel 8 at the bottom of the piston rod 7 contacts the ground, and the extension length of the piston rod 7 can effectively lift the stone 2, keeping the stone 2 away from the ground, which facilitates the subsequent transportation of the stone 2. At the same time, the equipment only requires one person to operate, without the need for two people to operate at the same time, making the equipment more compact and convenient to use.

[0027] When stone 2 is lifted, refer to Figure 1 To ensure stability between the two handles, the rotating frame 12 can be rotated so that the locking rod 13 on the rotating frame 12 rotates to the upper side of the other handle. Then, the locking rod 13 is pulled to compress the limiting spring 14 sleeved on the locking rod 13. When the locking rod 13 is above the insertion slot on the handle, the locking rod 13 is released. The pushing force of the limiting spring 14 is used to insert the locking rod 13 into the insertion slot. The shape of the rotating frame 12 limits the relative stability between the two handles, further ensuring the clamping stability of the two clamping plates 1. Then, the equipment can be moved to a suitable position.

[0028] This invention uses the extrusion plate 3 to compress the gas in the air chamber 4, which in turn drives the piston rod 7 to slide within the fixed tube 6. This, combined with the clamping force of the two clamping plates 1, effectively lifts the stone 2. Furthermore, the auxiliary wheel 8 at the bottom of the piston rod 7 allows for easy movement of the stone 2 by a single person, further improving the device's mobility and preventing inconsistent movement and force caused by two people moving simultaneously, which could affect the transport of the stone 2. The device's simple and compact structure further enhances its practicality and ease of use.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
