[0003] The current mine machinery push cylinder cannot flexibly adjust the pre-tightening force of the spring to adapt to different mine operation environments, which leads to the inability to adjust the buffering force of the mine machinery push cylinder according to the specific application scene, so that the application scene of the mine machinery push cylinder is limited, and therefore a push cylinder for mine machinery is needed to solve the above problems. UTILITY MODEL CONTENTS

[0006] By setting the above structure, when the mine mechanical push cylinder can adapt to different application scenarios and effectively provide the required buffer force, the deformation parameters of the buffer spring and the damper can be adjusted by adjusting the sliding ring, and the buffer force provided by the buffer spring and the damper for the mine mechanical push cylinder will change in the process of changing the deformation parameters of the buffer spring and the damper. Through such adjustment, the mine mechanical push cylinder can provide appropriate buffer force for different work tasks, whether large or small, to ensure efficient and safe operation, and also improve the flexibility and practicality of the mine mechanical push cylinder. In addition, the cooperation of the buffer spring and the damper can effectively absorb and disperse impact force during the pushing process, reduce mechanical vibration, and thus protect the push cylinder barrel and connected parts from damage as much as possible.

[0007] As a preferred scheme, the top of the mounting base is provided with a push cylinder barrel, and the surface of the push cylinder barrel is provided with an oil delivery pipe.

[0008] As a preferred scheme, the top of the push cylinder barrel is provided with a piston rod, and the top of the piston rod is provided with a connecting end.

[0009] As a preferred scheme, the bottoms of the three limiting protection barrels are fixedly connected with the top of the mounting base, and the inner walls of the limiting links are fixedly connected with the surface of the piston rod.

[0010] As a preferred scheme, the top of the adjusting sliding ring is fixedly connected with the bottoms of the three buffer springs, and the top of the adjusting sliding ring is fixedly connected with the bottoms of the three dampers.

[0013] By setting the limiting sliding rod and the limiting sliding groove, the two work cooperatively with the guide positioning rod, the adjusting sliding ring and other components to form a precise guide and limiting structure, thereby ensuring the trajectory accuracy of the mine mechanical push cylinder during movement and preventing work failure caused by deviation or shaking as much as possible, so as to improve the accuracy and safety of the whole operation. Meanwhile, the close cooperation of the limiting sliding rod and the limiting sliding groove reduces the friction and wear during the pushing process of the mine mechanical push cylinder, thereby prolonging the service life of the mine mechanical push cylinder as much as possible.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] This invention, by setting up an adjusting slip ring, a buffer spring, and a damper, ensures that the mining machinery push cylinder can adapt to different application scenarios and effectively provide the required buffering force. The adjusting slip ring allows for adjustment of the deformation parameters of the buffer spring and damper. As the deformation parameters of the buffer spring and damper change, the buffering force provided by the buffer spring and damper to the mining machinery push cylinder also changes. Through this adjustment, the mining machinery push cylinder can provide appropriate buffering force for different tasks, whether large or small, thereby ensuring efficient and safe operation. This also improves the flexibility and practicality of the mining machinery push cylinder. Furthermore, the combined use of the buffer spring and damper can effectively absorb and disperse impact force during pushing, reducing mechanical vibration and thus protecting the push cylinder barrel and connected components from damage as much as possible.

[0016] This invention, by setting a limiting slide rod and a limiting slide groove, works in conjunction with components such as the guide positioning rod and the adjusting slip ring to form a precise guiding and limiting structure. This ensures the accuracy of the trajectory of the mining machinery push cylinder during movement and minimizes operational errors caused by deviation or shaking, thereby improving the overall accuracy and safety of the operation. At the same time, the tight fit between the limiting slide rod and the limiting slide groove reduces friction and wear during the pushing process of the mining machinery push cylinder, thus extending the service life of the mining machinery push cylinder as much as possible.

Limiting rods 603 are slidably connected to the inner walls of the three limiting grooves 602. Buffer springs 604 and dampers 605 are fixedly connected to the bottom of each of the three limiting rods 603. Each of the three limiting protective cylinders 601 has an adjusting groove 606 on its surface. A limiting ring 607 is fixedly connected to the top of each of the three limiting sliding rods 603. A reinforcing connecting pipe 608 is fixedly connected to the surface of the limiting ring 607. Adjusting rings 609 are slidably connected to the inner walls of the three adjusting grooves 606. Three guide positioning rods 610 are slidably connected to the inner walls of the adjusting rings 609. Multiple positioning holes 611 are respectively opened inside the three guide positioning rods 610. The inner walls of the positioning holes 611 are used for... The system is equipped with a positioning rod 612. By adjusting the slip ring 609, buffer spring 604, and damper 605, the mining machinery push cylinder can adapt to different application scenarios and effectively provide the required buffering force. The deformation parameters of the buffer spring 604 and damper 605 can be adjusted by adjusting the slip ring 609. As the deformation parameters of the buffer spring 604 and damper 605 change, the buffering force provided by the buffer spring 604 and damper 605 to the mining machinery push cylinder will change. Through this adjustment, the mining machinery push cylinder can provide appropriate buffering force for different tasks, whether large or small, thereby ensuring efficient and safe operation and improving the flexibility and practicality of the mining machinery push cylinder. In addition, the combined use of the buffer spring 604 and damper 605 can effectively absorb and disperse impact force during the pushing process, reduce mechanical vibration, and thus protect the push cylinder 2 and connected components from damage as much as possible.

[0024] The top of the mounting base 1 is provided with a push cylinder 2, and the surface of the push cylinder 2 is provided with an oil supply pipe 3.

[0025] The top of the push cylinder 2 is provided with a piston rod 4, and the top of the piston rod 4 is provided with a connecting end 5.

[0026] The bottoms of the three limit protection cylinders 601 are fixedly connected to the top of the mounting base 1, and the inner wall of the limit linkage 607 is fixedly connected to the surface of the piston rod 4.

[0027] The top of the adjusting slip ring 609 is fixedly connected to the bottom of the three buffer springs 604 respectively, and the top of the adjusting slip ring 609 is fixedly connected to the bottom of the three dampers 605 respectively.

[0028] The bottom of the three guide positioning rods 610 is fixedly connected to the top of the mounting base 1.

[0029] The positioning rod 612 is inserted and connected inside the adjusting slip ring 609 and the guide positioning rod 610. By setting the limiting slide rod 603 and the limiting slide groove 602, the two work together with the guide positioning rod 610, the adjusting slip ring 609 and other components to form a precise guiding and limiting structure. This ensures the accuracy of the trajectory of the mining machinery push cylinder during movement and can prevent operational errors caused by deviation or shaking as much as possible, thereby improving the accuracy and safety of the overall operation. At the same time, the tight cooperation between the limiting slide rod 603 and the limiting slide groove 602 also reduces friction and wear during the pushing process of the mining machinery push cylinder, thereby extending the service life of the mining machinery push cylinder as much as possible.

[0030] The working principle and usage process of this utility model are as follows: To ensure the mining machinery pusher cylinder can adapt to various application scenarios and effectively provide the required buffering force, firstly, the positioning rod 612 is pulled out from inside the adjusting slip ring 609 and the guide positioning rod 610. The operator can push the adjusting slip ring 609 upwards or downwards. When the adjusting slip ring 609 slides and rises on the inner wall of the adjusting groove 606, it will cause the buffer spring 604 and damper 605 to deform accordingly. During the deformation of the buffer spring 604 and damper 605, the operator needs to adjust the pressure according to the actual application. The scenario is carefully adjusted. For example, in large-scale operation scenarios that require increased cushioning force, the operator will push the buffer spring 604 and damper 605 to a position that can provide greater cushioning force to reduce the impact of the machinery during operation. In small-scale operation scenarios that require reduced cushioning force, the operator will adjust the buffer spring 604 and damper 605 to a position that can reduce the cushioning force to improve operational stability. Afterward, the operator will re-insert the positioning rod 612 into the adjusting slip ring 609 and the guide positioning rod 610 to achieve fixation.
