This utility model relates to the technical field of fully mechanized mining equipment. It provides a hydraulic support height limiting mechanism and a hydraulic support. The height limiting mechanism includes a limiting body and a connecting structure. The limiting body is disposed on the hydraulic support base and is used to abut against the hydraulic support connecting rod to limit the descent height of the hydraulic support top beam. The connecting structure is used to detachably connect the limiting body to the hydraulic support base. This design meets the minimum size requirements for lowering or transporting the hydraulic support underground, and the limiting body will not shift under force, resulting in higher reliability. Furthermore, the minimum support height of the hydraulic support top beam can be adjusted simply by disassembling and replacing a specific model of limiting body, making it more versatile.

[0004] While the hydraulic supports described in the aforementioned documents can effectively complete various operational tasks, the replacement and disassembly process of their telescopic column cylinders is relatively complex and difficult. This often leads to extended maintenance time and reduced production efficiency. Therefore, a quick installation structure for the telescopic column cylinders of hydraulic supports has emerged.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0026] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a quick-installation structure for a retractable column cylinder of a hydraulic support, comprising:

[0027] The support mechanism 100 includes a connecting shell 101, an auxiliary rod 102 connected to the side wall of the connecting shell 101 via a bearing, a connector 103 fixedly installed on the side wall of the connecting shell 101, and a support assembly 104 disposed in the inner cavity of the connecting shell 101.

[0028] The adjustment mechanism 200 includes a connecting seat 201 hinged to the side wall of the connecting shell 101, a support shell 202 fixedly installed on the side wall of the connecting seat 201, a connecting component 203 disposed in the inner cavity of the support shell 202, and an auxiliary component 204 disposed in the inner wall of the connecting shell 101 to cooperate with the connecting component 203.

[0029] Specifically, the support assembly 104 includes a base plate 104a hinged to the side wall of the connector 103, a mounting base 104b fixedly installed on the inner wall of the base plate 104a, and a limiting plate 104c fixedly installed on the side wall of the mounting base 104b. The support assembly 104 also includes a mounting groove 104d formed in the inner wall of the base plate 104a, a baffle 104e fixedly installed in the inner cavity of the base plate 104a, and a reserved groove 104f formed in the side wall of the mounting base 104b.

[0030] Furthermore, the reserved groove 104f in the mounting base 104b engages with the bottom of the telescopic column cylinder, facilitating the installation of the cylinder and ensuring the stable operation of the device after the cylinder is installed.

[0031] Preferably, the connecting assembly 203 includes a fixing plate 203a fixedly installed on the inner wall of the support shell 202, and a card seat 203b fixedly installed on the side wall of the fixing plate 203a. The connecting assembly 203 also includes a movable plate 203c hinged to the inner wall of the support shell 202, and an abutment 203d fixedly installed on the inner wall of the support shell 202. The connecting assembly 203 also includes a retainer 203e fixedly installed on the side wall of the abutment 203d, and a slot 203f provided on the side wall of the abutment 203d.

[0032] The slot 203f engages with the top of the cylinder, while the fixture 203e facilitates the use of bolts to fix the end of the cylinder, ensuring that the cylinder can drive the support to move during extension and retraction, thus ensuring the convenience of using the device.

[0033] The auxiliary component 204 includes a connector 204a connected to the side wall of the card holder 203b via a bearing, a cylinder 204b fixedly installed on the side wall of the connector 204a, and a fixing seat 204c fixedly installed on the end of the cylinder 204b.

[0034] It should be noted that the fixed seat 204c is installed in the inner cavity of the connecting shell 101. When the oil cylinder 204b retracts, it can pull open the support shell 202 to ensure smooth installation and disassembly of the cylinder body. The base plate 104a, the connecting shell 101 and the support shell 202 are connected to form a complete hydraulic support.

[0035] In use, when the hydraulic cylinder 204b retracts in the auxiliary component 204, the fixed seat 204c cooperates with the support shell 202 to pull the card seat 203b, causing the support shell 202 to move upward. Then, the bottom of the telescopic cylinder is placed into the reserved slot 104f. The limiting plate 104c and the baffle 104e work together to ensure accurate positioning of the cylinder. Next, the hydraulic cylinder 204b continues to retract, and the connector 204a pushes the support shell 202, causing it to move downward and adjusting the position of the cylinder so that the end of the cylinder is aligned with the slot 203f. After the slot 203f engages with the cylinder, bolts are used to connect the cylinder to the fixing device 203e, finally completing the installation of the cylinder.

[0036] In summary, firstly, the cooperation between the fixed base 204c and the support shell 202 ensures that the support shell 202 can move smoothly upward when the cylinder 204b retracts. This design not only reduces friction and wear but also improves the smoothness of operation. Secondly, the pulling action of the retaining seat 203b effectively drives the movement of the support shell 202, allowing the bottom of the telescopic cylinder to be accurately placed into the reserved slot 104f. The synergistic effect of the limiting plate 104c and the baffle 104e further ensures the precise positioning of the cylinder, avoiding misalignment during installation. Next, As the hydraulic cylinder 204b continues to retract, the connector 204a pushes the support shell 202 downward. This step cleverly adjusts the position of the cylinder body, allowing the end of the cylinder body to be precisely aligned with the slot 203f, greatly improving the installation accuracy. Finally, after the slot 203f engages with the cylinder body, bolts are used to connect the cylinder body to the retainer 203e. This not only enhances the stability of the connection but also provides long-term reliability. Overall, this design improves installation efficiency, reduces maintenance costs, and enhances the performance and lifespan of the entire auxiliary component 204.
