Description

Technical Field

[0001] The utility model relates to the field of stone handling devices, and particularly to a convenient step stone handling device. Background Art

[0002] As a high-grade building decoration material, stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facility construction. The common stones on the market are mainly divided into natural stones and artificial stones. Stones are often used for decoration because of their beautiful appearance, and are also used for the laying of road curbstones or outdoor steps.

[0003] During the construction of on-site roads and outdoor steps, large and integral stones are often used in design to improve the overall decorative beauty effect, such as large curbstones, step stones, etc. However, due to their large mass, these large stones often require multiple people to cooperate during handling and installation. Therefore, not only does it lead to low construction efficiency, but there are also certain safety risks. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a convenient step stone handling device that can conveniently transport heavy large curbstones and step stones in view of the current situation of the prior art.

[0005] The utility model is realized by the following technical solutions: The utility model provides a convenient step stone handling device, which includes a carrier frame, a roller assembly, a carrier rod assembly and a clamping assembly. The carrier frame is composed of a base and a rotating support rotatably connected to the upper end of the base. The roller assembly is located at the lower end of the carrier frame. The carrier rod assembly is rotatably connected in the rotating support. The clamping assembly is fixedly installed on one side of the lower end of the carrier rod assembly.

[0006] By adopting the above technical solutions, the carrier frame can provide a support basis for the carrier rod assembly. The roller assembly can make the handling device move flexibly. The clamping assembly can clamp large step stones, facilitating transportation.

[0007] Further, the roller assembly is composed of side rollers rotatably connected to both sides of the base, a front wheel frame fixedly installed on the front side wall of the base, a front roller hinged to the front end of the front wheel frame, and a rear wheel frame fixedly installed on the rear side wall of the base. A universal wheel is rotatably connected to the lower end of the rear wheel frame.

[0008] By adopting the above technical solutions, the side rollers can improve the lateral stability of the handling device during operation. The front roller and the universal wheel can ensure the basic load stability of the handling device during operation.

[0009] Furthermore, the connection between the rear wheel frame and the universal wheel is a telescopic structure. A travel cavity is formed inside the rear wheel frame. A sliding rod is slidably connected inside the travel cavity. A spring member is fixedly installed on the top wall inside the travel cavity. The lower end of the spring member is fixedly connected to the sliding rod. The universal wheel is fixedly installed at the lower end of the sliding rod.

[0010] By adopting the above technical solution, the sliding rod can perform telescopic sliding along the travel cavity under the action of the spring member. When the handling device is loaded with heavy objects, the universal wheel is pressed, thereby driving the sliding rod to compress the spring member and simultaneously contract into the travel cavity, so that the side rollers contact the ground and jointly bear the gravity of the load. After the handling device unloads the heavy objects, the spring member will release the pressure, causing the sliding rod and the universal wheel to slide out of the rear wheel frame, making the side rollers suspended. The universal wheel and the front rollers cooperate to provide the moving function for the handling device, and the universal wheel can increase the flexibility of its steering.

[0011] Furthermore, the load rod assembly is composed of a load-bearing rod and an adjusting rotating rod. Through holes are formed in the side wall of the load-bearing rod. Connecting shaft holes are formed at the corresponding positions of the rotating support and the through holes. The through holes and the connecting shaft holes are of the same size. There are multiple through holes. The adjusting rotating rod is inserted into the through holes and the connecting shaft holes and is rotatably connected.

[0012] By adopting the above technical solution, the adjusting rotating rod can ensure the stable rotational connection between the load-bearing rod and the rotating support, and can perform corresponding displacement adjustment according to different usage requirements.

[0013] Furthermore, one end of the load-bearing rod is formed with a hand-held end, and the other end of the load-bearing rod is formed with a hanging end.

[0014] By adopting the above technical solution, it is convenient for the staff to control and manage the handling device.

[0015] Furthermore, the clamping component is composed of a suspension seat, a front suspension clamp seat hinged to one end of the suspension seat, and a rear suspension clamp seat hinged to the other end of the suspension seat. The suspension seat is a rotatable carrying rod. A rotating shaft is connected through the junction of the front suspension clamp seat and the rear suspension clamp seat. Both the front suspension clamp seat and the rear suspension clamp seat can perform rotational movements based on the suspension seat and the rotating shaft.

[0016] By adopting the above technical solution, when the clamping component is pulled upward, it can undergo a morphological change similar to the pressing of scissors, enabling the front suspension clamp seat and the rear suspension clamp seat to clamp the stepped stone materials.

[0017] Furthermore, clamping plates are fixedly installed on the corresponding end faces of the front suspension clamp seat and the rear suspension clamp seat, and anti-slip patterns are provided on the corresponding side walls of the clamping plates.

[0018] By adopting the above technical solution, the clamping stability of the clamping plate is ensured, and it is avoided that the stepped stone easily falls off.

[0019] The utility model has the following beneficial effects compared with the prior art:

[0020] By providing a stepped stone handling device composed of a carrier frame, a roller assembly, a carrier rod assembly and a clamping assembly, the utility model can conveniently and quickly handle large stones during on-site road construction operations or outdoor step construction operations, without the need for multiple people to cooperate. It can not only reduce the operation cost, but also improve the construction efficiency. In addition, certain safety risks can be avoided. Description of the Drawings

Detailed Embodiments

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] As Figures 1-3 shown, a convenient step stone handling device in this embodiment includes a carrier frame 1, a roller assembly 2, a carrier rod assembly 3 and a gripping assembly 4. The carrier frame 1 is composed of a base 101 and a rotating support 102 rotatably connected to the upper end of the base 101. The roller assembly 2 is located at the lower end of the carrier frame 1. The carrier rod assembly 3 is rotatably connected inside the rotating support 102. The gripping assembly 4 is fixedly installed on one side of the lower end of the carrier rod assembly 3. Among them, the carrier frame 1 can move based on the roller assembly 2. The carrier rod assembly 3 can adjust its rotation and inclination based on the rotating support 102. When the gripping assembly 4 is lifted upward, its lower end can close inwards under the action of its own gravity, thereby realizing the gripping operation.

[0030] As Figure 2 、 Figure 4 and Figure 5 shown, the roller assembly 2 is composed of side rollers 201 rotatably connected to both sides of the base 101, a front wheel frame 202 fixedly installed on the front side wall of the base 101, a front roller 203 hinged to the front end of the front wheel frame 202, and a rear wheel frame 204 fixedly installed on the rear side wall of the base 101. A universal wheel 206 is rotatably connected to the lower end of the rear wheel frame 204. The roller assembly 2 can provide a sufficiently stable moving effect for the handling operation of the handling device.

[0031] As Figures 3-5 shown, the connection between the rear wheel frame 204 and the universal wheel 206 is a telescopic structure. A stroke cavity 207 is formed inside the rear wheel frame 204. A slide rod 205 is slidably connected inside the stroke cavity 207. A spring member 208 is also fixedly installed on the top wall inside the stroke cavity 207. The lower end of the spring member 208 is fixedly connected to the slide rod 205. The universal wheel 206 is fixedly installed at the lower end of the slide rod 205. When the handling device is loaded with heavy objects, the universal wheel 206 is stressed, which will drive the slide rod 205 to compress the spring member 208 and at the same time contract into the stroke cavity 207, so that the side rollers 201 contact the ground to jointly bear the gravity of the load, thereby increasing the overall stability of the handling device and preventing tipping. When the handling device unloads the heavy objects, the universal wheel 206 and the slide rod 205 will be ejected under the action of the spring member 208, so that the side rollers 201 are suspended, and the universal wheel 206 and the front roller 203 cooperate to provide the moving function for the handling device. The universal wheel 206 can increase the flexibility of its steering.

[0032] As Figure 2 and Figure 3As shown in the figure, the load-carrying rod assembly 3 is composed of a load-carrying rod 301 and an adjusting rotating rod 303. A through hole 302 is provided on the side wall of the load-carrying rod 301. A connecting shaft hole 103 is provided at the corresponding position of the rotating support 102 and the through hole 302. The through hole 302 and the connecting shaft hole 103 are of the same size. The adjusting rotating rod 303 is inserted into the through hole 302 and the connecting shaft hole 103 and is rotationally connected; the adjusting rotating rod 303 can tilt and adjust the load-carrying rod 301 based on the rotating support 102, and the rotating support 102 can be rotationally adjusted based on the base 101. There are multiple through holes 302, enabling the staff to select different connection positions according to different requirements, improving the flexibility of use of the handling device.

[0033] As Figures 2-4 shown, one end of the load-carrying rod 301 is formed with a hand-held end 304, and the other end of the load-carrying rod 301 is formed with a hanging end 305. The staff can tilt and rotate the load-carrying rod 301 through the hand-held end 304, enabling the handling device to complete the gripping operation in different directions;

[0034] As Figures 1-3 shown, the gripping assembly 4 is composed of a suspension seat 401, a front suspension gripping seat 402 hinged to one end of the suspension seat 401, and a rear suspension gripping seat 403 hinged to the other end of the suspension seat 401. The suspension seat 401 is a rotatable carrying rod. A rotating shaft 405 runs through the joint of the front suspension gripping seat 402 and the rear suspension gripping seat 403. Both the front suspension gripping seat 402 and the rear suspension gripping seat 403 can rotate based on the suspension seat 401 and the rotating shaft 405. When the hand-held end 304 of the load-carrying rod 301 is pressed down, the hanging end 305 of the load-carrying rod 301 will tilt up. At the same time, the suspension seat 402 will move upward, and under the action of the gravity of the front suspension gripping seat 402 and the rear suspension gripping seat 403, it will contract and deform towards the middle, driving the upper connecting ends of the front suspension gripping seat 402 and the rear suspension gripping seat 403 to also gather towards the middle synchronously, so that the lower parts of the front suspension gripping seat 402 and the rear suspension gripping seat 403 can gather towards the middle synchronously in the form of scissors pressing based on the rotating shaft 405 to complete the gripping operation.

[0035] As Figures 1-3 shown, clamping plates 404 are fixedly installed on the corresponding end faces of the front suspension gripping seat 402 and the rear suspension gripping seat 403. The corresponding side walls of the clamping plates 404 have anti-slip patterns; ensuring the stable gripping effect of the front suspension gripping seat 402 and the rear suspension gripping seat 403 on the stepped stone materials.

[0036] The specific implementation process of this embodiment is as follows: During use, the staff can control the displacement of the handling device through the hand-held end 304. When it is necessary to grasp and clamp, the grasping and clamping assembly 4 can be moved to the stepped stone, and the stepped stone is positioned between the front suspension clamp seat 402 and the rear suspension clamp seat 403. Then, the hand-held part 304 is pressed down, causing the hanging end 305 of the load-bearing rod 301 to tilt upwards, simultaneously driving the suspension seat 402 to move upwards, and under the gravitational action of the front suspension clamp seat 402 and the rear suspension clamp seat 403, it undergoes a contraction deformation towards the middle, driving the upper connecting ends of the front suspension clamp seat 402 and the rear suspension clamp seat 403 to also converge towards the middle synchronously. As a result, the lower parts of the front suspension clamp seat 402 and the rear suspension clamp seat 403 can converge towards the middle synchronously in a scissor-like pressing and closing form based on the rotating shaft 405, completing the grasping and clamping operation. At the same time, continue to press down the hand-held part 304 so that the grasping and clamping assembly 4 can grasp the stepped stone, and then it can be transported to a suitable position for placement and use. When the handling device is loaded with heavy objects, the universal wheel 206 is stressed, driving the sliding rod 205 to compress the spring member 208 and simultaneously contract into the stroke cavity 207, causing the side rollers 201 to contact the ground to jointly bear the gravity of the load, thereby increasing the overall stability of the handling device and preventing tipping. When the handling device unloads the heavy object, the universal wheel 206 and the sliding rod 205 will be ejected under the action of the spring member 208, causing the side rollers 201 to be suspended, and the universal wheel 206 and the front roller 203 cooperate to provide the moving function for the handling device. The universal wheel 206 can increase its steering flexibility.
